It would appear in the ACM "SICMICRO" Newsletter, and we would, of course, credit the source. I have no idea where this particular gem originated, but I remember seeing it at RCA in 1961 or 1962. J. R. DOUGLAS General Electric Co. 13430 N. Black Canyon Highway Phoenix, Ariz. 85029 Ed. Note - Your comments are appreciated, and you are welcome to reprint the "The Empty Column" with our standard reprint clause. My copy of the parable about a "New Notation" which appeared in your January issue was attributed to an article titled "Simplified Chemical Coding" by William J. Wiswesser, copyright 1951, Willson Products, Inc., Reading, Pa. LAWRENCE J. PRINCE, Chairman Dept. 0/ Systems Analysis School 0/ Applied Science Miami University Oxford, Ohio 45056 I was extremely gratified when I discovered that you had reprinted "The Empty Column: A Parable About a 'New Notation' of Long Ago" in your January issue. I wrote that parable twenty years ago, and never in my wildest dreams would I have believed that it could have reached such deeply rewarding honorable mention. WILLIAM J. WISWESSER The Chemical Notation Association 3103 River Rd. Reading, Pa. 19605 Applause for APL I was pleased to see the article "APL: A Perspicuous Language" in your November issue [page 24]. Garth Foster did an excellent job of describing the features of APL which make it such a powerful programming tool. Please note, however, that the IBM 1500 is not a computer, but a lowcost terminal system which may be attached to either an IBM 1130 or 1800 computer. The APL/1500 system operates with either CPU and supports up to 32 terminals. As an APL "old-timer", I am glad to see that the language is starting to get 4 its just due, and hope to see more APL articles in the future. THOMAS D.

Of course, for a long time computer people have had problems of how to "talk" to a computer. As a result, probably over 500 special languages have been developed for giving orders to the "idiot genius", the computer, of which COBOL, FORTRAN, LISP, APL, and others promise to be memorable languages. But computer programming languages are only a small part of the problem of the relation of language to reality. There is a more important part of the problem: what constructs should we designate, among the vast array of multiple stimuli from the real world? For a simple ex. ample, in French there are three words fOJ a device that keeps time, "montre, pendule, horloge", but in English only two, "clock" and "watch": the real world of devices for keeping time is divided up differently in French and English. Alan Watts in "The Way of Zen" (published by Pantheon Press, New York, 1957) remarks that: . . . We have no difficulty in understanding that the word "tree" is a matter of convention. What is much less obvious is that convention also governs the delineation of the thing to which the word is assigned . . . the way in which our culture has tacitly agreed to divide things from each other, to mark out the boundaries of our daily experience. Thus scientific convention decides whether an eel will be a fish or a snake, and grammatical convention determines what experiences shall be called objects and what shall be called events or actions. How arbitrary such conventions may be can be seen from the question, "What happens to my fist (noun-object) when I open my hand?" The object miraculously vanishes because an action was disguised by a part of speech usually assigned to a thing! In English the differences between things and actions are clearly, if not always logically, distinguished; but a great number of Chinese words do duty for both nouns and verbs so that one who thinks in Chinese has little difficulty in seeing that objects are also events and that our world is a collection of processes rather than entities. There is a game I like to play which emphasizes almost with a shock, how much of what we observe and remember is influenced and conditioned by the conventionally prepared patterns in our minds, by means of which we observe. Here is the game (presently called Macdonald's Game): 1. Preparation. Assemble two collections of 20 small objects each in two small boxes; also obtain a tray and a cover. The first collection consists of 20 small, common, household articles such as a tack, a pin, a key, a penny, etc. The second collection consists of 20 small very strange objects such as diverse metal stampings and fasteners. 2. Play. Out of sight of the players, the first collection (of common objects) is spread on the tray and covered. The tray is then uncovered in front of the players, and the 20 objects are displayed for 60 seconds. Then the tray is covered again, and the players write down from memory what they saw. Usually people can remember and list 6 only 15 to 17 of the objects. Then in the same way the second collection is displayed for just one minute. But this time people usually can name, describe, or draw pictures of, only 3 to 5 objects. I know of no better, quick demonstration that what people can look at and perceive is enormously influenced by the prepared patterns in their minds. As more and more applications of computers to real problems occur, there should result as a byproduct useful insights on how to delineate parts of reality, and make useful symbols. But in a more basic sense, we human beings deeply need more adaptable, less conventional patterns in our minds, so as to think better - and to escape limitations from culture, history, language, propaganda, etc. Consider George Orwell's remark in "1984" (published by Harcourt Brace, New York, many editions): The purpose of Newspeak was not only to provide a medium of expression for the world-view and mental habits proper to the devotees of Ingsoc, but to make all other modes of thoughts impossible . When a computer professional or information engineer enlists himself in the service of society and humanity, one of the questions he is faced with is: How do I increase my understanding of the world? How do I escape from the provincial world-view, mental habits, cultural conventions, biases, "Newspeak", etc., of my own country, community, and associations? There are some reasonable steps. One is to cut down on reading, listening, or watching information of little value propaganda, comic strips, entertainment, advertisements, commercials, columnists, news on trivial subjects, etc. Another is to read newspapers, magazines, articles, books, with focused purposes chiefly to look for answers to important, preselected questions. For example: Why did the secession,ist region of Nigeria, Biafra, receive such great publicity support in the United States press, before finally its leader Ojukwu fled in an airplane taking his Mercedes car with him? I have put together a list of some dozen books that, I think, are useful to help liberate one's mind from the overwhelming propaganda and Newspeak of today. We will be glad to send a copy of this list to any reader who circles No.2 on the Readers Service Card. The book I have most recently added to this list is "Teaching as a Subversive Activity",. by Neil Postman and Charles Weingartner (Delacorte Press, New York, 1969). About three quarters of this book seems to me very illuminating, although the remaining portion is expressed in such sweeping generalities that they "turn me off" (but perhaps I am 01 d-fash i oned !). We invite discussion in the pages of Computers and Automation of the problems here alluded to, in the interrelations of: language reality thought computers propaganda - communication. ~c.~ Editor } COMPUTERS AND AUTOMATION for March, 1970 ctoputer& When you go Octoputer, a 3 billion dollar communications company backs you up all the way.

HAS FORMED A NEW EDUCATIONAL ORGANIZATION, Control Data Education Institutes (CDEI) to provide multi-level computer training to customers, management, employees and the general public. An outgrowth of Control Data's price unbundling, CDEI will support five instructional areas: computer technology (entry level), advanced technology, management education, international education, and a franchising service. L. G. Kinney will be responsible for the five new divisions that make up CDEI. Following this announcement of plans for expansion of its commercial computer education operations, Control Data also revealed plans to reduce its number of personnel at its Minneapolis headquarters, and to cut other costs. A reduction in contracts for "large" computers from aerospace companies was cited by company officials as a major reason for the cutback. Control Data employs 15,000 people in Minnesota. SIGNIFICANT PROGRESS TOWARD REACHING INTERNATIONAL AGREEMENT IN KEYBOARD STANDARDIZATION was reported as the outcome of a recent meeting of the TC95/SC14, a Committee of the International Organization for Standardization. The first step taken by the Committee was to agree on a basic core comprising an alphabet of 26 letters, the numerals, fullstop and comma. The second step was to define a suitable layout for the alphanumeric part of the keyboard. Two standardized keyboards were then proposed by the Committee, one version in which national letters could be implemented, and a second version in which further graphic symbols could be used. Additional information about the work of the Committee may be obtained from D. Hekimi, the Secretary General of The European Computer Manufacturers Association, Rue du Rhone 114, 1204 Geneva, Switzerland.

LOCKHEED-CALIFORNIA COMPANY A DIVISION OF LOCKHEED AIRCRAFT CORPORATION Designate No. 19 on Reader Service Card MULTI-ACCESS FORUM liTHE INVASION OF PRIVACY AND A NATIONAL INFORMATION UTILITY FOR INDIVIDUALSI I - COMMENT L. A. Welke, Pres. International Computer Programs 2511 E. 46th St. Indianapolis, Ind. 46205 I noted with great interest the article on "The Invasion of Privacy and a National Information Utility for Individuals" appearing in your January 1970 issue [page 48]. And I must take issue with the conclusion of the author [Richard E. Sprague]. There should be no doubt in anyone's mind as to the happenings in and around a credit bureau file. The fact that information in these files is abused and misused should be common knowledge at this point. Obviously this information situation has developed in a legal. vacuum, to the detriment of the pUblic. New legislation will correct much of this merely by allowing the citizen to have access to any record, and to give him the right to know who is inquiring into his file would be sufficient to generate a self-policing system. It does not follow in any respect that any of the individual files currently in existence must, per se, be replaced by a master file run by a central authority such as the Federal Government, or anyone else. There is no reason to assume that a single national system would be any better or worse than the multiple local interest ones that would result from the legislation. In addition, there is no logical cause for a national data bank to be brought into existence and if there were, it could be done by private capital rather than public spending. The author of your article, Mr. Sprague, rightfully points out the amount of vested interest involved in the current setup. Any file is going to have vested interest surrounding it. For that matter any new legislation will not necessarily mean the removal of the vested interest - indeed, it might even cause a black market on individual information, which would then have to be allowed for in the new legislation. But after all, this is what human beings, society, and the business community is all about. This has been true for the age of man and will undoubtedly continue to be ture until a superior being emerges to replace us. These superior beings may not have manifested themselves as the leadership of the business community as yet, and this is unfortunate. By the same token, I have yet to see a trace of them in the group of public officials that supposedly serve people. 0 liTHE STATUS OF WOMEN IN THE FIELD OF COMPUTING I I Mary R. Standard 232 W. 16th St., Apt. 5R New York, N.Y. 10011 In regard to the article by Gerald H. F. Gardner (liThe Status of Women in the Field of Computing", January 1970, page 57), I should like to point out that the discriminatory practice of some newspapers in segregati'ng the "Help Wanted" ads by sex is not only unjust and shortsighted, but also illegal under Title 7 of the Civil Rights Act of 1964. The National Organization for Women (NOW) obtained a ruling from the Equal Employment Opportunity Commission (EEOC) which applies Title 7's specific ban against discriminatory help wanted advertising to sex discrimination as well as discrimination on the basis of race, color 10 - COMMENT or religion. While some newspapers have obtained an injunction to delay enforcement of this ban, other newspapers, including the New York Times have ceased to list jobs separately under "Help Wanted - Male" and "Help Wanted Female" categories, unless sex is a bona fide occupational qualification for the job. The enforcement of the ruling appears at the moment to still be somewhat cloudy, and I thank Mr. Gardner for his supportive sentiments. As a· female who was early discouraged from showing an interest in mathematics and other intellectual matters ("Boys don't like girls to be too smart," as my dear mother would have put it) and who later in life for economic among other reasons fought her way up from clerk-typist to programmer/analyst, l can only regret that observations such as Mr. Gardner's are still necessary. 0 COMPUTERS AND AUTOMATION for March, 1970 COMPUTER TURNS STUDENT ON I.

II. Letter to Call-A-Computer from Warren E. Brant, 2099 LaCrosse Ave., St. Paul, Minn. 55119 A year agO' last fall yaur campany made camputer service available to' St. Paul Schaals. One terminal was installed in Harding Sr. High Schaal and made available to' 12th grade students. My san, Jerry, happened to' be ane af the very fartunate students whO' was given an appartunity to' be expased to' the field af camputer sciences at this level. He had pretty well decided by this time that he wauld gO' an to' St. Paul Vacatianal fallawing graduatian, as his interests and best marks were in metal shap and mechanical drawing. That camputer turned him an. His math shat up to' straight A's! He was advised to' enter the University and try far engineering. We learned that Wiscansin State River Falls had an excellent math pragram and camputer center. He has just campleted his first quarter there halding his high scares in math and warking especially hard an his English. We cannat tell at this paint, af caurse, whether he will gO' an to' majar in math, physics, camputer sciences ar samething else but ane thing is far sure ... yaur camputer at Harding had a prafaund effect an his life, interest and destiny. We want yau to' knaw that. 0 IICOMPUTER PROGRAMMER TRAINEES CAN'T FIND JOBSII - COMMENT Dorothy Vezetinski, Supervisor Data Processing Placement C.T.C. Education Systems, Inc. 19728 Scriber Lake Rd. Lynnwood, Wash. 98036 This letter is in respanse to' the article "Camputer Pragrammer Trainees Can't Find Jabs" by Helen Salem, which was published in the August 1969 issue af Computers and Automation. I quate fram the article: "There is nO' demand far camputer pragrammer trainees." This may be true in Hillsbara, Oregan, but jab apenings are fairly gO' ad here. On December 12, far example, we graduated 17 persans fram aur Data Pracessing Caurse, Of these 17 peaple: 7 were placed in the surraunding area 1 went to' New Yark in respanse to' a review af his resume 1 persans' references were requested by Washingtan State Univ. 2 are being cansidered by a lacal insurance campany 2 went an to' cal lege 4 are still actively seeking jabs. Cansidering the jab temperature in this area, which is law at the mament, we feel this is a pasitive result. The average minimum starting salary available far aur graduates during December was $485. This disputes Mrs. Salem's camment that "Yaung peaple whO' have had nO' previaus data pracessing experience find staunch emplayer resistance to' hiring trainees whether ar nat they have taken special caurses which suppasedly allaw them to' be called 'trainee'." Where wauld we be if there were nO' inexperienced peaple to' be malded intO' the experienced Systems 0 Analysts af the future?

MARTIN LUTHER KING MEMORIAL PRIZE CONTEST - SECOND YEAR (Please post this notice) Computers and Automation has received an anonymous gift and announces the annual Martin Luther King Memorial Prize, of $300, to be awarded each year for the best article on an important subject in the general field of: The application of information sciences and engineering to the problems of improvement in human society. The judges in 1970 will be: Dr. Franz L. Alt of the American.1 nstitute of Physics; Prof. John W. Carr III of the Univ. of Pennsylvania; Dr. William H. Churchill of Howard Univ.; and Edmund C. Berkeley, Editor of Computers and Automation. The closing date for the receipt of manuscripts this year is April 30, 1970, in the office of Computers and Automation, 815 Washington St., Newtonville, Mass. 02160. The winning article, if any, will be published in the July issue of Computers and Automation. The decision of the judges will be conclusive. The prize will not be awarded if, in the opinion of the judges, no sufficiently good article is received. Following are the details: The article should be approximately 2500 to 3500 words in length. The article should be factual, useful, and understandable. The subject chosen should be treated practically and realistically with examples and evidence - but also with imagination, and broad vision of possible future developments, not necessarily restricted to one nation or culture. The writings of Martin Luther King should be included among the references used by the author, but it is not necessary that any quotations be included in the article. Articles should be typed with double line spacing and should meet reasonable standards for publication. Four copies should be submitted. All entries will 14 become the property of Computers and Automation. The article should bear a title and a date, but not the name of the author. The author's name and address and four or five sentences of biographical information about him, should be included in an accompanying letter - which also specifies the title of the article and the date. "Many people fear nothing more terribly than to take a position which stands out sharply and clearly from the prevailing opinion. The tendency of most is to adopt a view that is so ambiguous that it will include everything and so popular that it will include everybody ... , Not a few men who cherish noble ideals hide them under a bushel for fear of being called different." "Wherever unjust laws exist, people on the basis of conscience have a right to disobey those laws." "There is nothing that expressed massive civil disobedience any more than the Boston Tea Party, and yet we give this to our young people and our students as a part of the great tradition of our nation. So I think we are in good company when we break unjust laws, and I think that those who are willing to do it and accept the penalty are those who are a part of the saving of the nation." - From "/ Have a Dream" - The Quotations of Martin Luther King, Jr., compiled and edited by Lotte Haskins, Grosset and Dunlap, New York, 1968. Reverend Martin Luther King, Jr., was awarded the Nobel Peace Prize in 1964, when he was age 35. He was in jail in the United States more than 60 ti meso He was assassinated in Memphis, Tennessee, April 4, 1968. COMPUTERS AND AUTOMATION fo-r March, 1970 CAN A MACHINE BE CONSCIOUS? Dr. Kenneth M. Sayre Associate Professor of Philosophy University of Notre Dame Notre Dame, Ind. 46556 The Institute for the Study of Artificial Intelligence at the University of Notre Dame is using a computer to consider the ultimate philosophical question: What does it mean to be a conscious human being? A workable definition for consciousness is being sought by examining such related questions as, "Can a machine be conscious? If so, what would it be like?" The Institute believes its studies can offer two advantages to scholarship first, to create more flexible programs that increase the usefulness of the computer, and second, to use these programs to gain a clearer, more practical understanding of how human beings perform various tasks. Until the advent of the computer, philosophers had no laboratory in which to test their theories, while scholars in the sciences have long had the advantage of trying their ideas out in controlled experiments. Although the computer is limited as a tool for determining the worth of philosophical theories, it does provide some basis for accepting or rejecting ideas on how human beings perform basic intellectual tasks. In programming the computer to recognize lines of handwritten material, for example, it was found the machine had difficulty recognizing badly formed letters. Humans have an advantage in that they do not rely purely on form, but can reserve judgment on which letter is meant until the context of the word or sentence is clear. So the computer was then programmed to employ this flexible approach in identifying letters by telling the machine which letter combinations are statistically likely, and which are not. If confused by a badly formed letter, the computer could then consult these lists of likely combinations before making a choice. Such flexibility could be called a form of consciousness, though not on a level with that of a man, or even a cat. Actually we do not expect that the future will produce machines capable of consciousness as complete as man's - a machine which is aware of its actions, feels affection and pain, and exercises will or volition. The reason such a machine will probably never exist is not because it would be impossible from a technical point of view. There simply is no practical reason to commit the resources it would take to create one. 0 TOTAL SIZE OF EXHIBITIONS AT FUTURE JOINT COMPUTER CONFERENCES WILL BE LIMITED Dr. Richard I. Tanaka, Pres. American Federation of Information Processing Societies 210 Summit Ave. Montvale, N.J. 07645 The American Federation of Information Processing Societies (AFIPS) will limit the total size of future exhibitions held in conjunction with its Joint Computer Conferences. Future exhibitions will be held to a maximum of 1000 booths, in order to maintain the high quality of the exhibit program, and to assure that the exhibition does not escalate to a prohibitive size. We strongly feel that any increase in size beyond the present level would diminish the usefulness of the exhibits for those attending the conferences, and would tend to detract from the overall focus of the conference and the technical program. There are several additional changes that are being made relative to the Joint Computer Conferences. One is that the option of registering only for the exhibits is being eliminated, in order to assure that those attending the conference itself will have an appropriate opportunity to view the new developments in hardware and software being shown. There will also be changes in the conference registration fees. Fees for individuals who are not members of AFI PS' constituent societies wi II be increased to $40 from the previous level of $30. Of this amount, $10 is applicable towards membership in anyone of the AFIPS constituent societies. The registration fee for both members and nonmembers includes one copy of the Conference Proceedings, which may also be purchased separately. The registration fee for full time students will be increased to $5.00; the fee for members of AFIPS' constituent societies will remain at $20. 0 1970 FALL JOINT COMPUTER CONFERENCE - CALL FOR PAPERS L.

Metaxides, Chairman CODASYL Data Base Task Group Bell Telephone Laboratories 2F-104 2 Jackson Drive Cranford, N.J. 07016 A report on data management has been completed by the Data Base Task Group of the Conference on Data Systems Languages (CODASYL). The report is the result of several years of voluntary effort by special ists in data management from many companies who manufacture computers as well as major computer users. The report contains proposals and detailed specifications for a Data Description Language and a Data Manipulation Language. The Data Description Language is used to describe a data base. The Data Manipulation Language, when associated with the facilities of a host language such as COBOL, PL/l, ALGOL, JOVIAL, FORTRAN, etc., allows manipulation of data bases described by the Data Description Language. The major objectives of the Data Base Task Group in developing its proposals were to: • achieve flexibility without data redundancy; i.e., to allow data to be structured in the manner most suitable to each application, regardless of the fact that some or a II of that data may be used by other applications. • allow more than one run-unit to concurrently retrieve or update the data in the data base. • provide and permit the use of a variety of access methods against an entire data base or portions of a data base. • provide protection of the data base against unauthorized access of data and from untoward interaction of programs. • allow the user to plan and implement his system as if he had a virtual memory at his disposal. • provide the Data Base Manager with the capability to control the physical placement of data. • allow the declaration of a variety of data structUres ranging from those in which no connection exists between data elements to network structures. • allow the user to interact with the data while being relieved of all of the mechanics of maintaining the structural associations which have been declared. • allow programs to be as independent of the data as current techniques will permit. In developing its proposals the Data Base Task Group paid special attention to keeping its proposals in line with what can be currently implemented and was careful to avoid concepts and proposals which it considered to be unattainable within the present state of technological development. Its proposals are thus of immediate interest to all computer users, and the Data Base Task Group hopes that its report will be widely studied and commented upon. Copies of the report (approximately 200 pages) are available at $4.00 per copy, prepaid, from the Association for Computing Machinery, 1133 Avenue of the Americas, New York, New York, 10036.

Bryan, Director Psychological Sciences Division Office of Naval Research, Code 450 Washington, D.C. 20360 ((Informal peer discussions leading to learning ought to be among the prime benefits to be derived from student terminal-sharing at the time of contact with the material to be learned." Modern educational technology has recognized the potential of computer time-sharing as a means for providing truly individualized instruction. It is important that these evolving systems be designed to permit and encourage person-to-person interactions which are generally recognized to be desirable, but which as yet have received little systematic attention from the system designers. Exponents of Computer-Assisted I nstruction (CAl) frequently depict the ideal CAl system as one where each student has his own private carrel. There he pursues his studies without interruption or distraction. Typically, the computer with which the student is to interact has modern time-sharing capabilities. Consequently, he cannot even tell whether or not anyone else is using the system at the same time he is using it (let alone interact with the other person in a common pursuit of knowledge). The CAl enthusiasts are correct in their desire for systems which can provide the kind of splendid isolation that current systems provide. Undoubtedly, there are some times, some topics, and some students who would benefit from such isolation. However, it is not always desirable and it is not a necessary consequence of time-sharing. Systems can be devised which permit and even stimulate desirable student-to-student interactions. It is hoped that the considerations presented in this article will so influence the design of future CAl systems. From a research standpoint, very little has been done in the area of student-to-student interaction in timeshared CAl systems. To all intents and purposes, there are no hard data. But, several exploratory efforts have been made and they indicate that such approaches have real promise. It is interesting to examine a few of these efforts and to speculate regarding other possible arrangements for promoti ng student-to-student interactions. Isolated Student A series of simpl ified diagrams is used throughout this article to focus the discussion. The diagrams in the series This article is based on a talk given at the Symposium on Education and Information Science, Ohio State University, Columbus, Ohio, June 24, 1969. 18 are cumulative in the sense that each embellishes its predecessor. New features are identified as they are introduced. Figure 1 depicts a single terminal system capable of conversational interaction between a central processing unit (CPU) and a student (S) by means of a terminal (T). Figure 1. Simplified schematic of a single terminal system serving a single student. As it stands, such a system has no time-sharing capability (in the sense in which the term is used here) and, of course, there can be no student interactions where just one student is involved. Most current CAl programs seem to have been designed with such a system in mind. Although they serve more than a single student, they do so to share costs and to share resources not to promote student-to-student interactions. Terminal Sharing However, such interactions become possible when a second student is added as shown in Figure 2. This figure shows two students sitting in front of a single terminal. Experiments with such a "terminal-sharing" arrangement have demonstrated that each student learned as well under these circumstances as he might have been expected to learn if he had had the terminal all to himself (Grubb, 1965). This is an important finding from an economic standpoint since it suggests that it may not be essential to provide a separate terminal to each and every student in a CAl system. Although the experiment described by Grubb did not try to exploit the potential advantages of having a second student present during the COMPUTERS AND A UTOMATION for March, 1970 of thinking about the subject they are studying and ways of talking about it that prove useful when they extend their discussions beyond the carrel. A Two-Student Program Figure 2. An example of a "Terminal Sharing" serving two students at the same terminal. learning sessions, it is interesting to speculate how the student-to-student situation might have been exploited to promote learning by means of social facilitation, modeling, and observation. Discussion of these factors is beyond the scope of this paper, but the interested reader will find excellent treatments of them in Chapter 3 of Principles of Behavioral Modification (Bandura, 1969). One can think of two rather different schemes for dealing with the two-students-at-a-terminal case (i.e., terminal sharing). In the first of these, the computer program which would be used would be identical to the program which would be used if the terminal were occupied by just one student. The second scheme would employ a program tailored explicitly with the terminal-sharing situation. A One-Student Program As in example of the first scheme, assume that a program originally written for a single student is used. Assume, further that the program goes through the following loop. It asks a question, accepts a reply, evaluates the reply, provides "feedback" based upon the analysis of the reply, selects another question and performs the loop again until it runs out of questions or is instructed to stop. Student-to-student interactions under these circumstances can be governed by "responding rules" which are either informally agreed upon by the two students themselves, or enforced by some agent in control of the learning situation (e.g., a human monitor). Many examples of such responding rules leap to mind. One is to take "turn about." Another example is "if you are sure that you know the answer, give the other student a chance to answer first." Or, it might be desirable to allow "whoever knows the answer to supply it as quickly as possible." Or, the students could be required to talk it over until they both agreed upon an answer before it was entered into the system. Obviously, the use of different "responding rules" permits considerable flexibility. The rules are limited primarily by the ingenuity of the people who make them up. As an aside, it is interesting to note that some of these interactions in the terminal-sharing environment could be quite noisy. But, such noisy interactions are far more appropriate in the CAl environment than they would be in the conventional classroom learning situation. Compare, if you will, this CAl situation with two students sharing a terminal in a carrel with that of the same two students sitting beside each other in a conventional classroom where any attempt to communicate with one another disrupts the class and distracts the instructor. Carrels can easily be designed so students can engage in protracted, even heated, discussions without "holding up the class." As a matter of fact, informal peer discussions leading to learning ought to be among the prime benefits to be derived from student-to-student interaction at the time of contact with the material to be learned (not after class). Systems like this permit communication between students in their own language. They create a condition where students, through their common experiences, develop ways COMPUTERS AND AUTOMATION for March, 1970 The second genera I scheme for hand ling student-tostudent interactions in a terminal-sharing environment is to design the computer program to take the dual occupancy of the terminal into account in an explicit manner. Again, there are numerous ways that this can be done. For example, each question can be addressed to each student by name. In this manner the program keeps track of the progress of each student and enforces the response rule in effect at any given time. The program could even deal with the students differentially on the basis of their personal response histories. The following fictitious example might result from such an arrangement. Assume that John and Mary are terminal-sharing. PROGRAM: John, who discovered America? JOHN: PROGRAM: Columbus. Mary, when did Columbus discover America? In 1066. MARY: PROGRAM: JOHN: PROGRAM: MARY: PROGRAM: Do you agree with that Johnny? No, it was in 1492. Is that right Mary? I don't know. I don't think dates are important. The study of history is certainly a lot more than memorizing a lot of dates. But, there are some dates that are commonly used to sort of punctuate history. The date that Columbus discovered America is such a date in this country. John, tell Mary how you manage to remember 1492 as the year when Columbus discovered America. Etc. Fictitious examples are easy to write. Whether or not it would be possible to write a program to handle two students at the same time in this way is, at present, an empirical question. But, in principle, such a program could be written. It is used here simply to suggest how a program might interact with each terminal-sharing student as an individual and, at the same time, encourage them to interact with each other. Simple Linking But, let us move on from the simple terminal-sharing case to true time-sharing cases where each student has his own terminal in his own carrel. Figure 3 shows the Figure 3. An example of a interaction. "student·to·student" computer·mediated basic system configuration with multiple terminals. Although only two terminals are shown in the figure, comments regarding the relationships between these two may be extended to any specified number of terminals in a larger, multi-terminal complex. 19 Since, in the ardinary time-sharing system, terminals are functianally isalated, the first step in providing student-ta-student interactian in such a system is to' write additianal programs to' cantrol the intercannectian af specified terminals withaut "clabbering" the entire system. There are many degrees af intercannectian. The simplest is to' allaw ane terminal to' "eavesdrap" an anather. Anather simple type af intercannectian permits ane terminal to' "call" anather terminal via the camputer. These twa capabilities are cambined in the CONNECT pragram at Praject PLATO (Bitzer, Hicks, Jahnsan and Lyman, 1967) sa that the authar af a CAl pragram can manitar the pragress af a student warking an a pragram. If the student's behaviar indicates that he is having trouble, the authar can type aut a message which appears an the student"s terminal. The message identifies the authar, expresses his willingness to' help, and inquires as to' the nature af the student's difficulties. This arrangement was devised as an aid to' an authar whO' wished to' revise a CAl pragram, and it cantained ather features nat described here. Hawever, the same type af program might permit twa students to' work tagether an an exercise by allawing each to' loak aver the ather's shaulder, sa to' speak, and to' cammunicate freely with each ather via the intercannected terminals. Under thase circumstances, it might even be useful to' permit them to' talk directly to' each ather by telephane as well. Nate that the CONNECT pragram simply arranges far the intercannectian af the terminals and does nat prescribe the nature af the communicatian between the terminals. In ather wards, the cammunicatian is bath unguided and unlimited. where ane af the terminals is accupied by a student and the ather is accupied by a piece af electronic equipment which receives autputs from a terminal and pravides inputs to' it. A diagramatic representatian af this situatian is given in Figure 4. The daub Ie-headed arrow indicates a r- - --, I I Prog. L ____ I I ...J I G~-B-8o Figure 4. Arrangement where an item of electronic equipment serves as a "student" in a student·to·student computer.mediated interaction. "hard-wire" cannectian between the equipment and Terminal-2. Signals passing to' the right in the diagram and entering the equipment change its state. Signals passing from the equipment to' the left pravide detailed indicatians af the status af the equipment. In this manner, the student-experimenter sitting at Terminal-1 makes entries at his keybaard which signal the equipment to' change its status. The results af thase changes are returned to' the camputer where they can be processed and returned to' the student-experi menter. Prescribed Interactions Interactive Laboratory Experimentation The TALK program, which was develaped by Bitzer and Praf. Harold Guetzkaw (then af Northwestern University) and their assaciates, went a step further (Hicks, 1966). It explared the passibilities af intercannected terminals with respect to' a program af man/ camputer simulatian. In the TALK program, cantingency specificatian stared in the camputer cantrolled the intercannectian af terminals and limited the nature af the interactians amang them. This pragram control af the nature of the interactians is a significant feature and we shall return to' it later. But, far the present, just sa the idea wan't be taO' vague and mysteriaus, assume a situatian where twa campetitars in a camputerized business game are situated at different terminals. Assume, alsO', that the program allaws them to' cammunicate and negatiate with each ather via the computer in matters pertaining to' (say) municipal bonds, but daes nat allaw them to' cammunicate an any ather matters. This type af program cantrol aver the nature and cantent af the terminal-ta-terminal interactian is the feature af the TALK program which is af interest. One can easily see haw programs cauld be written to' require student-tastudent interactians at same paint af the teaching pragram and in regard to same tapics while restricting this type of interactian at ather paints in the sequence. My first appartunity to' abserve this type af arrangement was at the University af IIlinais where ane terminal af the PLATO system was accupied by an elabarate labaratary setup far advanced experiments in surface physics. Once set up, the experimental apparatus cauld be aperated fram ane af the ather terminals. There were several advantages to' this. Far instance, it reduced persannel hazard. It alsO' protected the equipment fram the bumbling ar inept experimenter in twa ways: mechanically, he cauldn't knock it aver ar physically misalign it, and since the camputer cauld be pragrammed to' interpret the cammands emanating fram a student-experimenter's terminal, it cauld "refuse" to' pass alang cammands that might be harmful to' the equipment if executed. (Actually, the experiment in paint was carried aut by seniar faculty members and I am nat certain that the pragram cantained such safeguards. But, abviausly, it cauld.) Far mare impartant, thaugh, was the fact that the data being 'generated by the experimental apparatus cauld be analyzed an-line, in real time under the cantral af the experimenter. Thus, pawerful mathematical and analytical techniques cauld be applied to' the data to' explare a wide range af variables and to' test aut variaus hypatheses withaut an extensive cammitment ardinarily required far a farmal labaratary investigatian. Such a situatian is especially suitable far early phases af investigatian since it encaurages the experimenter to' "play around with" thE:! variables sa as to' come to' knaw their interrelatianships better while planning mare farmal experiments.

Undaubtedly, it represents a "wave af the future" and may very well prave to' be a useful means far cammunicating knawledge to' students as well as a gaad way to' praduce it in the first place. But, aur purpase in discussing it here Terminal-to-Terminal Processing A program feature which builds upan the cancepts af prescribed interactians and adds to' them the vast capabilities af the camputer to' aperate upan the autput af one terminal (i.e., an the input to' the camputer supplied by ane terminal) as requested by the student lacated at the ather terminal. Althaugh I knaw af no case where such techniques are utilized where the terminals are bath occupied by students, there are same interesting cases 20 COMPUTERS AND AUTOMATION for March, 1970 is to show that terminals have been interconnected in a manner that applies the processing power of the computer to the information routed from one terminal to another. The next section will indicate how this capability is employed explicitly for teaching purposes. Stored Interaction Models A network with the processing capabilities just described is easily modified to incorporate a stored model of the interactions to be expected in the network. This model of the interactions that could occur then monitors the interactions that do actually occur and automatically causes the computer program to intervene under certain specified circumstances. The only real-life examples of this sort of interaction employ a piece of electronic equipment at one of the student terminals while the student-trainee sits at the other. Again the example is drawn from the work of Bitzer and his associates at Illinois; this time working in collaboration with Rigney and his colleagues from the University of Southern California. The dotted line added to Figure 5 permitted several modes of instruction. It could lead a neophyte through the procedures telling what to do and checking to be certain that he had followed directions. Or, it could pose a problem situation and intercede when the trainee's performance indicated that he was deviating from the model (which was not a simple step-by-step procedure). Or, it could allow him complete flexibility to do whatever he wanted to try to do, only interceding when he sought to do something that would damage the equipment or the trainee himself. Under those circumstances the computer simply refused to relay the commands of the trainee to the equipment. It could do this since all access to the inner workings of the transceiver was via the com-. puter. Even the front panel controls produced a signal which was interpreted by the program, evaluated in terms of the stored interaction model, and then, if appropriate, was relayed to the URC-32 for action. With such a program it is a simple task to incorporate comments which can be made to the student by the program to indicate what he had done wrong and what he should do next, if the program writer wishes to do so.

I ..J "hands·on" student/equipment indicates that the terminals were located in such a manner that the trainee had direct visual and manual access to the equipment at Terminal-2. This is to say, that he could see the equipment and could operate all of its front panel controls. The computer was connected to the equipment under study (a URC-32 which is a standard Navy radio transceiver) in such a manner that the computer could detect the exact positions of all front panel controls and indicators. As a consequence, whenever the student did anything to the front panel of the transceiver, the computer "knew what he had done." The objective of this arrangement was to instruct the trainee in the tuning, operation, and maintenance of this type of transceiver. The key to the program's success was the fact that the entire range of possible interactions between the trainee and the transceiver could be described in terms of a goal-oriented model of the interactions which could be represented in the computer program. Rigney and Towne describe the rationale for this type of computer program as being able "to manipUlate symbolic representations of task structures, recognizing actiongoal hierarchies, task constraints and antigoals wherever they are supplied separately from the task goal structure." (Rigney and Towne, 1969, page 117). This arrangement COMPUTERS AND AUTOMATION for March, 1970 With a little ingenuity an arrangement of this type can be extended to accommodate a two-person zero-sum game for instructional purposes. In addition to the basic functions of storing the rules of the game, seeing that they are followed, and scoring the game, the computer would be able to evaluate the play of each player against a model of the game which it had in storage. In this way, the program could keep track of each student-player's playing history, stage of learning and skill level. It could then adjust the parameters of the game accordingly. In a configuration such as that shown previously in Figure 2, a computer program could sit between two players who were playing against each other. It could control and oversee the manipUlation of symbols by each player and could intervene selectively to privately call each player's attention to aspects of his own play and that of his opponent. To make this more concrete, imagine that each terminal is equipped with a checkerboard display on which he can manipUlate checkers in the interest of becoming a better checker player. The game starts by one player making the first move (after having been selected by some random means of course). Then the other player moves. The program alters the displays to indicate the new locations of the pieces after each move. It enforces the rules of checkers and performs other "housekeeping functions." In addition, its stored model would enable it to evaluate moves. So if a player indicated that he wanted to make a foolish move, instead of executing it, the program could urge him to reconsider. Or, it could indicate the likely consequences of such a move. Similarly, if one player made a move that constituted a grave threat to the other the program could call the threatened player's attention to his plight. Of course, the checker playing illustration is introduced for the sake of simplicity. It is easy to think of other two-person zero-sum games that have greater social importance. The point is that the existence of stored models of the interactions "open up" the instructional situation in ways that can make student-to-student interaction both exciting and productive. The checker-playing example depends upon competition between players. However, if the program designer does not wish to foster such competitiveness, it doesn't take a great deal of imagination to devise situations which put a premium on co-operation among players. In such cases, the program simply pays off according to the extent to which 21 Figure 6. A fictitious competitive/co-operative team learning arrangement. each player demonstrates his ability to co-operate, to assist, to collaborate, or to participate as a member of a learning group. The above-mentioned concept suggests a combination of both competitive,ness .and co-operation, as in the following example, in which teams of students cooperate with their own teammates while competing against the other student teams. A Rich Competitive! Co-operative Learning Situation Figure 6 portrays five different teams, each of which is served by a terminal connected to a central processing unit. Each team has five student members. It is our objective to develop, to the maximum extent possible, three characteristics of each student. These characteristics are: the sUbstantive skills and knowledges associated with successful individual participation in the domain of interest, the team skills that enable each student to participate as an effective member of a team which must function as a cooperative group in competition with the other teams, and person learning and teaching skills required to upgrade the student's own competence as well as assisting other members of his team to upgrade theirs. For the purpose of the illustration, let us suppose that. each team is the governing board of a mutual fund. It is the responsibility of each team to invest its resources responsibly and profitably. Throughout the game transactions are handled by the computer. The program keeps continuous track of the relative success of each team. This results in a subscore for each member of each team which we shall call his Team Score (TS). Periodically during the extended period of the game, play is interrupted and each member of each team is independently tested to determine how well he understands the stock market and the factors which influence its fluctuations. Each player's Personal Score (PS) is a subscore based upon the cumulative average of his scores earned on these personal tests. A third subscore is derived by averaging the Personal Scores of all of the other members of a particular team. Let us call this subscore the Other 22 Member's Score (OMS). These three subscores are combined for each student to produce a Composite Score (CS), which is the ultimate basis for comparisons among students. For the sake of this illustration, let us assume that the pay-off schedule is such that students will work very hard to improve their composite scores. The Effect of Scores Now, as you can see, there are three ways that this can be done: by increasing each one's knowledge of the market, by improving the interactive skills of all the members of one's team, and by improving the team's investment decisions. A few extreme cases may clarify how this scoring arrangement directs each man to concentrate on areas of his own weakness and how social factors produce student-to-student interactions which are likely to influence learning under these circumstances. Consider, the case where S1 has a very high TS, a high PS, and avery low OMS and, therefore, a CS which could stand improvement. In such a case it looks like S1 is highly knowledgeable with regard to the market and is making all of the decisions on behalf of his team. The other members of his team, S2, S3, S4, and S5, have low personal scores which are dragging down S1'S composite score. The scoring scheme ought to put pressure on the other members to "hit the books" and study the charts so as to raise their personal scores. They should feel some responsibility toward S1 to do this since he is "carrying them on his back" in the inter-team competition. By the same token S1 should feel some pressure to work with the other members of the team to assist them to grasp the subtle dynamics of the market so as to increase their personal competence, raise their personal scores and thus raise the composite score of every other member of their own team. Let us take a second case where one member of the team has an abnormally low score, the team has a moderate score, and all of the other members of the team have moderate scores. Under these circumstances, the low score member should feel the social pressure to improve his COMPUTERS AND AUTOMATION for March, 1970 Now from Datapro 70.

They may attempt to instruct him or to get him to discipline himself. It is not unlikely that the other members of the team might take a dim view of the idea of the low-scoring member "goofing off" at night as long as his score remained so low. Also, imagine a third case where all team members have high PS and therefore high OMS but the team has a low score. This situation would develop if the team had not learned how to operate as a team. Perhaps all members are vying for leadership. Perhaps they need to learn how to plan, to organize, or to allocate their individual efforts to various aspects of the problem. I n any case, they need to do something to improve their team score. It would behoove them to get together and talk about ways that they might do that. Possibly the computer-based system itself could be made available for some after-hours drill on the development of team skills. The important thing to notice in all of these examples is that the scoring system seeks to motivate the students to interact with other members of the team, and that through such interaction the students get useful practice. They learn to learn. They learn to teach. They learn to cooperate. They learn to persuade. They learn a lot about the investment business. In short, the team learning situation is quite complex. There is good experimental evidence (Glaser & Klaus, 1966, 1969) to indicate that very careful contingency management is called for if all of the benefits of training are to be gained and if the situation is to be avoided where some members of the team don't pick up bad habits. And one can see how the capabilities of the computer lend themselves to this type of student-to-student interaction. COMPUTERS AND AUTOMATION for March, 1970 Conclusion Present trends in computer-assisted instruction have not emphasized interaction between students. In this article I have attempted to build a case for what I believe to be an important direction for future instruction - and to show that isolation among students in a computerized system is not necessary and may not even be desirable. The interaction examples, both real and fictitious, ought to be considered carefully. It is hoped that they will serve as a useful basis for those who would like to conduct further investigation into the stimulation of learning by means of student-to-student interactions in CAl systems. 0 References Bandura, A., Principles of Behavior Modification.

Kent Morton Kiewit Computation Center Dartmouth College Hanover, New Hampshire 03755 Quite possibly the question most frequently asked of those concerned with educational technology is: "How can your justify the use of computers in education?" In its various forms, this question seeks justification in terms of cost per student, how effectively the standard material can be presented, results obtained, and even the possibility of teacher obsolescence. It's a fair question. However, it would also have been fair to ask: "How can the use of audio-visual materials in education be justified?" in the days when record players, records, projectors, language labs, and closed circuit television comprised the whole scope of educational technology. That was as recently as ten years ago. Yet there was nowhere near the degree of controversy over the advantages and disadvantages of audiovisual equipment as there is today over the pros and cons of the far more versatile computer. I would say there are two major reasons why this contrast in controversy exists. Familiarity with Audio-Visual Devices Th,e ,first is that record players, recorders, projectors, and teleVISion - the standard inventory of audio-visual equip~ent were all household items long before they arrived on the educational scene. Almost everyone had operated at least one of the items; most had seen all of them in use more than once; and many owned more than one of them. Consequently, they were acquainted with the specific function and capabilities of each, knew their value, and their limitations. In short, there was no mystique surrounding these machines at the time when they began to be used in education. , I have been speaking primarily of adult society, in partlcu.la.r those ad~lts who are responsible for making the decIsions regarding the acquisition and deployment of A. Kent Morton received his B.A. from Amherst College in 1966. While studying for his Master's degree in Slavic languages and Literatures at Harvard University, he became interested in educational technology, and particularly the role of computers in education. After receiving his degree in 1969, he ioined the staff at the Kiewit Computation Center at Dartmouth College as the Coordinator of the Regional College Consortium Proiect. 24 such equipment. The same may be said, however, for most students: only a very small percentage of students were introduced to these machines for the first time in school. Lack of Familiarity with Computers Unfortunately, the same cannot be said of computers, nor will it be said for some years to come. Although steadily diminishing, there persists a pervasive mystique about computers. Whereas they are every bit as stupid as a record player or a projector, their capabilities are not so restricted or well-defined. One record player may perform with greater fidelity than another, but its never-changing task is soley to play records. I suppose there is some security in the knowledge of the constantcy of its function compared with the ever-changing, ever-elusive role of computers. Cost The second reason is more simply stated: computers cost more than record players, projectors, and television. Therefore, a school or college can purchase a great deal more A-V equipment per tax dollar than it can computing equipment. That is the current argument, at any rate, vastly oversimplified. Whether or not one receives comparable educational value is a subject of hot debate. With these comments in mind, I'd like to return to the original question of justification and try to answer it in the light of my encounters with time-sharing at Dartmouth. First, it seems to me that teacher obsolescence is an unfounded concern. Virtually no one in educational technology today seriously entertains the possibility that computers in any form will replace teachers. Instead, more will be expected of teachers who are colleagues of computers; they must become better, not fewer. The reasons for this will become clearer later in this discussion. Cost per student will not be treated here either, for two reasons. First, I wish primarily to illustrate the educational value of computing. If we were not forced to consider educational computing from a financial point of view, we would concern ourselves entirely with its educational value, which is fitting. Secondly, cost figures have little me~ning unless their origin is very precisely defined, which space does not allow here. Costs vary greatly according to the hardware and software used, communications equipment and distances,·· type(s) of interface, whether the service is supplied by a commercial source or an educational institution, and, very importantly, the type of instruction attempted by the system. COMPUTERS AND AUTOMATION for March, 1970 ((The necessity for approaching every problem clearly and logically is probably the most valuable learning experience associated with computing in education." Educational Strategy I would like to turn now to the topic of educational strategy as it concerns computers, the kinds of uses to which computers have been put, and their impact on "learning" and "education". Second, he learns that computers don't know everything. In fact, he soon realizes, to his great delight, that he knows more than the computer, and that the computer doesn't understand anything that he hasn't told it. This realization greatly helps in destroying the mystique, and will eventually place computers in the comfortable category now occupied by A-V equipment. Computer-Controlled Instruction Educational strategy evolves from a decision as to the proper relationship between the student and the computer: basically, which is to be master? The most publicized approach, Computer-Assisted I nstruction, casts the computer in the role of master. In this mode it makes sense to speak of "presenting the standard material" to the student. The customary ingredients of a classroom education are presented to each student via cathode ray tube or remote terminal, and each student is put through his paces until he masters as much of the material as he can. This can be a very effective technique in certain areas and for certain categories of students. The students learns but is he being educated? Is he learning to use his own mind to extrapolate from what he sees before him, or is he merely learning what he sees? Educational value aside, I am convinced that one of the chief disadvantages of the CAl strategy is its perpetuation and reinforcement of the mystique surrounding computers. A student who is spoon-fed by an all-wise, nevererring machine is going to end up believing a computer is an unconfoundable genius that can do anything, and of course nothing could be further from the truth! Learner-Controlled Instruction The second strategy has no widely recongized name as yet, which seems to make it psychologically more difficult to accept. It advocates the importance of the student learning to program the computer. This strategy has proved tremendously successful at Dartmouth College and the forty colleges and secondary schools which have access to the Dartmouth Time Sharing System (DTSS). While these schools appreciate the value of the computer as a ready source for stored facts, they feel it is far more useful as a problem-solving tool which the student can learn to program. The student, therefore, is master and teacher. Advantages This strategy has three major advantages. First, it removes the restrictions of a programmed curriculum, enabling the student to use the computer to solve the problems he needs to solve, not just the problems someone else presents to him. COMPUTERS AND AUTOMATION for March, 1970 Thorough Understanding Third, and most important in my estimation, is the fact that the student must thoroughly understand every problem he submits to the computer for solution. If he doesn't, he can't program the computer for it, and it won't be solved. This necessity to approach every problem clearly and logically is probably the most valuable learning experience associated with computing in education. Those are the sorts of results which justify the use of computers in education. Examples There are concrete examples to support the preceding argument. Two years ago two time-shared terminals came to Vermont Technical College as part of a project sponsored by the National Science Foundation to investigate the feasibility of using computers in education. Today, Vermont Tech requires a programming course, which is given concurrently with introductory calculus and emphasizes the use of the computer as a problem-solving tool. Seven problems are required; they differ from year to year, but they include calculating mortage rates, working with doubly-subscripted arrays, and using Newton's method for approximating the roots of various functions, including logarithmic and trigonometric functions as well as polynomials of varying degree. This situation is now common at many of the schools. One student who failed calculus twice has become so inspired by computing that he passed the course with flying colors the third time, and is now, in conjunction with another student, writing a program for the admissions office at his school. Agricultural students use the computer to determine the proper mix of several types of feed for livestock, a proportion which depends upon the type of animal, its age, activity, sex, and nutritional requirements in general. Social science instructors are using programs which manipulate the extensive data files developed by Project IMPRESS at Dartmouth. The main point of these programs is multi-variable analysis. In all the colleges which have access to DTSS, the computer is used in virtually all courses which deal 25 repeatedly with large amounts of quantitative data. Reduction of data taken in laboratories and plotting lines of best fit by computer are extremely common practice. Not so common, however, are the programs of one Civi I Engineering Department, which check surveying data taken in the field for accuracy, or determine vertical curvature, stopping distances, drainage rates, and other factors for different types, conditions, and sections of highway. A mechanics department uses the computer to determine optimum gear and pulley ratios. Several language departments use the computer for drill in vocabulary and grammar. The Department of Radiology at one medical school is adapting a program which analyzes the contour of the patient's body and determines where, and at what angle of entry, to administer the proper amount of radiation to treat a cancerous growth without endangering vital organs. Virtually all the colleges in the Dartmouth Regional Consortium use the computer in differential equations courses, to demonstrate the concept of limit in calculus, and as an analytical tool for determining properties of equations, curves, and series. Programming Means Understanding Students and faculty alike at these schools report an increased understanding of concepts presented. Simply stated, it boils down to "If you can program it, you understand it thoroughly." For their part, programs that demonstrate through their output a concept such as convergence help a student to see what the concept really implies, and to get a feel for it as well. Course Grading Programs As far as administrative usages are concerned, most schools are now adopting their own versions of grading programs which generate each student's courses, credit hours, grade, quality points, semester and cumulative index. One college runs a program which shows how many grades of what type are given in each department. The admissions program referred to before is designed to compute the number of students who have applied to each program at a particular time; additional information is given regarding sex, geographical origin, SAT scores, previous education, and whether or not the application fee has been paid! A good indication of the success of the project at Dartmouth lies in the number of colleges which have purchased, or have plans to purchase, their own computers so that they will have more computing power available at their schools. Two or three terminals are woefully inadequate servants for an entire student body. Summary In summary, the strategy in which the student programs the computer is a most important' component in contemporary education. It contributes to the development of a disciplined mind that copes clearly and logically with the problems it encounters, rather than relying on memorized facts. And it produces a population of people who are not alarmed at the prospect of being colleagues of a computer, because they understand what computers are just as clearly as they understand what record players are.

Ferguson Learning Research and Development Center Univ. of Pittsburgh Pittsburgh, Pa. 15213 ({If learning specialists and psychologists can determine the variables which represent the best input for making wise decisions) then a computer can be programmed to perform the task which a single teacher would no doubt find impossible to manage." It seems widely agreed that if an educator provides for the uniqueness of each learner (whether this uniqueness is due to ability to learn, or rate of learning, or interest, or goals, or other factors), then the probability of learning increases. If this premise is valid, then any educational plan should adapt its instruction to individuals. Now, if differential treatment for individuals is desired, then the educational system must insure that such treatment can and does occur. This article gives a summary ·of the key features of a system for individualized education, and describes some potential uses of the computer in a school environment so that it will attend to the different needs of individuals. Variables in Education Individually Prescribed Instruction (IPl)l, a system developed by the Learning Research and Development Center at the University of Pittsburgh, represents the adaptation of a variety of instructional strategies to providing for individual requirements. Cooley and Glaser!! list three component variables in the system: (1) educational goals, (2) individual capabilities, and (3) instructional means. The educational goals for a particular individual are determined in a variety of ways. Society requires that an individual be capable of reading and writing; the individual with the aid of teachers and parents may elect a specific program of study; the student may choose or not choose to study a particular unit of instruction; and with the teacher's assistance short term goals are set for him dai Iy. Such decisions may in part be made on the basis of the individual's capabilities, the proficiencies which represent the repertoire of skills he has acquired in the course of formal and informal learning experiences. The content and processes he learns and the manner in which they are learned represent instructional means. Although a II three components are subject to change over extended periods of time, it is assumed that each can be well defined for a particular act of instruction. In light of the preceding perceptions regarding the educational process, the following sequence of operations can be used to define a general model of instruction. 3 Richard L. Ferguson is a Research Associate at the University of Pittsburgh's learning Research and Development Center. He received his Ph.D. from the University in 1969, and received a post-doctoral appointment to work with the development of computer management instruction and testing for the Center's Individually Prescribed Instruction (lPI) Project. COMPUTERS AND AUTOMATION for March, 1~70 (1) The goals of learning are specified in terms of observable student behavior and the conditions under which this behavior is to be manifested. (2) When the learner begins a particular course of instruction, his initial capabilities, those relevant to the forthcoming instruction, are assessed. (3) Educational alternatives suited to the student's initial capabilities are presented to him. The student selects or is assigned to one of these alternatives. (4) The student's performance is monitored and continuously assessed as he learns. (5) Instruction proceeds as a· function of the relationship between measures of student performance, available instructional alternatives, and criteria of competences. (6) As instruction proceeds, data are generated for monitoring and improving the instructional system. A simple analysis of these operations reveals that each could be successfully implemented without benefit of computer assistance. However, it seems entirely reasonable to hypothesize that the computer could provide substantial support for the professional staff in such a system. Further, it could be utilized in such a way as to take maximum advantage of its unique capabilities for computer-assisted instruction (CAl) and computer-assisted testing (CAT). The Computer Attempts at individualization in conventional classroom environments by the most imaginative of teachers are likely to lead to at best modest success and at worst nervous frustration. The major difficulty in such an undertaking, that which is most I ikely to overshadow its successful implementation, is the management of instruction for large numbers of students with widely varying competencies and needs. The initiation of a system like IPI, although solving the immediate problem of providing instructional sequences for students with diverse needs, does not obviate the management problem. Rather, it shifts the emphasis of management from providing a lesson for a student to providing the optimum instructional strategy for him given the maximum amount of information which would be useful in making such a choice and the restrictions imposed by available instructional resources. An even more crucial element of individualization may be the management of the student's schedule. Given the rapid growth of his proficiencies in a particular curriculum and 27 more labored progress 'in another, global goals might best be accomplished by re-allotting time assigned for instruction in the former curriculum for study in the latter. Management Many of the professional staff associated with the development of I PI have stated that management of the educational process ranks extremely high among their con,cerns. It is in the management domain that computers, in concert with their roles in testing and instruction, promise applications in education which will yield a perceptible improvement in the planning and implementation of individualized instruction. The remarks which follow represent a general description of how the computer might be applied in an IPI school. Not all of the applications described are suited for every curriculum in the instructional program. That is, the manner in which the computer is used will require adaptation to the unique features of each curriculum. The specific services which the computer will be called upon to provide are: (1) collection and storage of data, (2) information retrieval, (3) testing, (4) instructional planning, and (5) instruction. It is stressed that each of these functions can be performed without benefit of the computer but would require large expenditures of the time and energies of the school staff. None of these functions are independent of all others and thus each will be examined in terms of its role in the total educational environment. Instructional Planning The determination of immediate and long range instruc. tional plans for an individual may well prove to be one of the keystones for success in a program of individualized instruction. Setting reasonable, attainable goals for a student, or better yet, having him participate in defining those goals may well influence the rate and quality of his progress in achieving them. Thus, the first step in the educational process is the establishment of a plan tailored for instruction of the individual. The elementary school does not afford the opportunity for setting grossly different long range goals for each student. To a large extent, elementary school educators have translated the demands of society into a well-defined program of studies which provide no real opportunities for substantive deviations. That is, decisions regarding what track to enter or what courses to take reflect long range planning which is apt to be non-existent in the elementary school. However, the computer can prove to be extremely valuable in planning for more immediate action. By monitoring a student's progress in each of many curricula, the computer can, provided decision rules by the professional staff, suggest adjustment of the student's instructional timetable to concentrate upon some area in which he is particularly weak. Planning can be further served by the computer in the day to day instructional decisions which are required. At Oakleaf, an experimental IPI elementary school, the curriculum has been planned so as to provide for realizing goals in a variety of ways. For example, in mathematics the teacher and/or student may select elements from among a set of instructional materials to achieve proficiency in a given skill. In science, a student's short term goal may be to learn all he can about some subject of immediate interest to him. From a large collection of books he may choose to read one of interest to him and in so doing progress toward the terminal goals of the reading curriculum. 28 To cite a specific example of the computer's potential for assisting in the planning of educational activities, consider IPI science. With fewer content-oriented demands placed upon it, the goals of elementary science can be achieved and still permit the individual 'to pursue interests not shared by all other students. With some effort expanded on identifying the structure of available lessons, the computer could be programmed to allow a student to specify a lesson in the curriculum he wished to study and then supply him with a tailored list of prerequisite lessons. Such a list would be compiled as the intersection of the skills required and the skills he has already acquired and would serve as a plan for his instructional activities. Computer Testing and Instruction Primary to the progress of students toward achievement of their goals is the continuous assessment of their competencies. In IPI, unit placement tests are given to ascertain the student's proficiency on each of the objectives which comprise a unit. A placement test for a unit with eight objectives would consist essentially of eight subtests, each measuring competency, in one of the skills. Outcomes from the test would then be used to determine instructional activities directed at removing the deficiencies which had been detected. Once instructional activities have been successfully completed, a posttest measuring the objectives of the unit would be administered. Thus, tests represent a large investment of time for both the students and the aides who score them. In the interest of easing the problems just described and with the explicit goal of tailoring testing as well as instruction to individuals, a measurement procedure has been developed which takes advantage of the known prerequisite relationships which exist among the objectives of a unit. 4 The notion of prerequisite relationships can be represented by the structure pictured in Figure 1. In this structure, objective 8 is the terminal objective and all other objectives are prerequisite to it. Thus, it is assumed that if 8 is mastered, all prerequisite objectives must also have been mastered. By a similar analogy, if the student is not proficient in objective 5 then it can be inferred without testing that he is not proficient in either objective 7 or 8. The essential features of the testing technique include the computer generation of test items from item forms stored in the computer, the application of Wald's sequential probability ratio test for decisions regarding proficiency of an objective according to arbitrarily set criteria, and branching as a function of the hierarchy of objectives being tested, thus not requiring the testing of each skill but only those for which no inferences based on the hierarchical structure can be made. Such a test relieves the problem of scoring and provides for immediate storage and retrieval of data. In addition, experience with such testing has shown that it can substantially reduce the investment in time required by testing with the added bonus that more reliable test information could be obtained from the computer-assisted test than from the conventional fixed length test because the errors resulting from decisions made about a student's proficiency in an objective could be controlled as a function of the item-sampling technique employed. Diagnostic Tests Success with the technique of testing just described has encouraged interest in the development of diagnostic tests tailored to detect the types of errors made on a single objective. By using the computer to analyze error types, COMPUTERS AND AUTOMATION for March, 1970 o extract them from the data, then a computer can be programmed to perform the task which a single teacher would no doubt find impossible to manage. 8 Data Requirements 7 I 4 ll' GJ I 5 " 2 3 l' I 1 Figure 1 Testing Hierarchy for an Eight-Obiective Unit in IPI Mathematics Each of the computer applications which has been described either generates or requires the retrieval of data. Computer-assisted testing generates large quantities of data, all of which must be available for the computer to suggest prescriptions for instruction. If instructional decisions are to reflect due consideration of all relevant information about an individual, provision must be made for storing such data. The problem of what to store is a matter for the concern of instructional technologists and psychologists. That is, they must determine which data; intelligence measures, aptitude tests, and general background information can be combined with a daily expanding base of instructional and test data to provide the substance for decisions related to planning future goals or specifying immediate instructional strategies. The requirements related to the structure for the data files is not at all independent of what is to be stored. Whatever the data requirements, a flexible and efficient system for data management is required. It seems likely that instructional technology will be more backward in identifying the necessary components for optimizing decision making than will be computer technology in providing for its convenient use. Apart from the use already implied for the data generated in the IPI system, it is also used for systematic evaluation and improvement of the system. By examining data obtained through its operation, system procedures and instructional materials undergo constant scrutiny and occasional alteration. In addition, as new knowledge about learning and instruction accrues, often by experimentation within the system, it is integrated into IPI. The computer facilitates both the storage and retrieval of pertinent research data and in addition provides the computational power for its analysis. The Small Computer prescriptions directed at eliminating the observed deficiencies could be generated at the conclusion of a testing session at a computer terminal. These prescriptions would be determined as a function of available resources and if it exists, information regarding the individual's style of learning. The latter might include information such as whether he requires intensive detailed lessons or less formalized instruction. A particular prescription may include a lesson administered by the computer at a teletype terminal or a cathode ray tube (CRT). The qualifier "may" is invoked since CAl lessons are not likely to be available for all objectives, nor is there any reason to believe that such lessons if available, would be suitable for all students in all situations. Apart from the fact that prescriptions for instruction could be conveniently generated concurrent with testing, there is additional reason for suggesting this role for the computer. The teacher, in making decisions affecting a child's instruction, is apt to use only that information which is readily available to her. Whether or not all pertinent data is accessed and properly processed in determining an instructional decision, a decision will be made. The computer by permitting instant identification of available instructional materials and access to data relevant to making a decision as to their best use for the given individual, can serve as a valuable tool to the student or teacher in making short term instructional plans. Further, if learning specialists and psychologists can determine the variables which represent the best input for making wise decisions and how systematically to COMPUTERS AND AUTOMATION for March, 1970 Experiences which have been the product of the initial implementation of a computer management system for IPI, supplemented by studies with CAT and CAl, have resulted in the evaluation of the hypothesis that a small computer could support educational management, computer testing, and some CAl lessons. To test this hypothesis, a Learning Research and Development Center project is being supported by funds from the National Science Foundation. Plans for the school initially include a small local computer with a terminal configuration consisting of a mixture of CRT's and teletypes. The scopes wi II be used for testing in mathematics, for generating tentative prescriptions as a function of test outcomes, and the teletypes for producing hard copies of output when required. Teacherpupil planning sessions will be centered around the CRT's, thus permitting the quiet and efficient retrieval of data required by the teacher. They will also be used for CAl and for inputting data not directly entered via CAT and CAL 0 References 1C. M. Lindvall and J. O. Boivin, in Programed Instruction, P. Lange, Editor.

Schwetman Computation Center The Univ. of Texas at Austin Austin, Tex. 78712 ((During the past three years) over 100)000 jobs submitted through remote consoles have been processed." A large modern university has diverse needs for computing facilities. At The University of Texas at Austin, these needs are being satisfied by a large central computer system with several methods of user access. One of these methods is a remote console system called RESPOND. RESPOND has been in service at the University for almost three years; during this time, over one hundred thousand remotely submitted jobs have been processed. The users of RESPOND have found it to be a convenient and versatile way of accessing the powerful central computing system. The System Herbert D. Schwetman received a B.S. in Mathematics from Baylor University in 1961 and a Sc.M. in Mathematics from Brown University in 1965. He worked for IBM for three years as a Medical Applications Programmer. Currently, he is pursuing a Ph.D. in Computer Sciences at The University of Texas at Austin. He is also employed by the Computation Center there as a systems programmer and has maintenance responsibility for the RESPOND system. 30 The Computation Center at The University of Texas at Austin provides most of the computing service for a large university community of some thirty thousand students. The central computing system consists of a Control Data Corporation (CDC) 6600 computer and a locally modified descendant of the SCOPE 2.0 operating system. This large, fast system presently satisfies the computing needs of the university by processing about fifty thousand jobs per month. The characteristics and configuration of the system are described in Appendix A. Access to the 6600 system is provided in three distinct ways: 1. "Over-the-counter", using one of the central card readers, 2. Through any of five satellite computers, or 3. Through RESPOND, a remote console system. 1 RESPOND is a multi-access, remote batch entry system with limited file editing capabilities. While not possessing some features norma Ily associated with a comprehensive time sharing system,2,3 RESPOND does allow remote users to conveniently use the 6600 as a tool in their problem solving. While providing this remote service, RESPOND is still economical in the sense that it requires only a part of the system resources available,4 in other words, normal job COMPUTERS AND AUTOMATION for March, 1970 THE UNIVERSITY OF TEXAS THE COMPUTATION CENTER AUSTIN, TEXAS DISPLAYS RATES READERS 1200c/m PRINTERS 1000 11m PUNCH 250 c/m TAPES 120000 ch/sec 200 USERS TERMINAL f 1 1 CDC 8231 SYSTEM CDC 1700 SYSTEM PDP 7 SYSTEM PEARCE HAlL ROOM 105 ENGINEERING SCIENCE 18 - BIT WORDS TAYlOR HAll ROOM 113 1000 11m 8M CH 12- BIT WORDS 1200 ACCElERATOR CONTROL ROOM 18- BIT WORDS c/m MAGNETIC TAPE DRIVE SDS 930 SYSTEM MAGNETIC TAPE DRIVES 20K ch/sec.

This article demonstrates that the somewhat limited capabilities provided by a system like RESPOND are still sufficient to allow remotely located users to accomplish a wide variety of significant computing tasks. RESPOND A remote console user communicates with RESPOND through a teletypewriter and a telephone line. He can enter commands and manipulate files consisting of programs and data from his keyboard. Furthermore, he can have RESPOND diagnostics and the contents of his files displayed on his teletypewriter printer. His files are automatically saved for his use at a later time. The classes of RESPOND commands are as follows: 1. Commands to create arid edit files, 2. Commands to submit jobs to the 6600 input queue, and 3. Commands of a housekeeping or utility nature. An important type of file which a remote console user can create is one consisting of system control cards. By creating such a file and submitting it to the 6600 input queue, the remote user has access to all facilities which are ava i la bl e to over-the-counter users of the computer, and these control cards are identical to those employed by users with other means of access to the 6600 system. System resources such as the Fortran compi ler, system utility routines, and magnetic tape and disk files, are the same for users of all three methods of computer access. However, since jobs. submitted by RESPOND receive a boosted input priority, they are limited to a running-time limit of 127 central processor seconds, and must fit within a block of 32,000 words of central memory. The original version of RESPOND was provided by CDC to the Computation Center in March, 1967. Since that time, extensive modifications have been made locally to that original version. These modifications include those which correct mistakes (bugs), those which extend a user's capabilities, and those which make operation of the system more practical. Modifications Some of, the user-oriented modifications include a new command, PLOT, which allows the contents of a RESPOND file to be diverted to a CALCOMP 565 remote plotter which can be attached tp a teletypewriter. Another added feature is the CONVERSE command which permits interaction between a remote console and a program running in the system. In the current configuration, access to RESPOND is through a dial-up systetn Which consists of twenty-five telephones, thus limiting the number of simultaneous users of RESPOND to twenty-five. RESPOND can service up to sixty telephones. One hundred and eighty-five users hold RESPOND passwords and maintain over fourteen hundred files within the system. Since installation of RESPOND in 1967, over one hundred thousand jobs have been submitted through RESPOND. These jobs represent about twelve per cent of the jobs processed by the 6600 during that period.

The total amount of RESPOND user connect-time on that day was 130.2 hours. These figures are fairly typical of daily use of the system. Monthly user connect-time for a period of ten months is shown in Figure 1. In September, 1969, the maximum number of passwords was raised from 250 to 500.

One user, in the School of Architecture, has found RESPOND to be a valuable tool in the study of form and verbal representations of form. By using the PLOT command in RESPOND, he is able to graph his program output on a remote plotter in his office. In a graphics-oriented field like architecture, the ability to have a graphic representation of an object of interest often conveys much more information than other representations. Using the remote plotter and RESPOND, graphic files can be quickly generated and viewed. The rapid turnaround of RESPOND-submitted jobs is extremely valuable because a user is able to go quickly from an idea to the graphic representation of that idea. The physical presence of the teletypewriter and plotter in the School of Architecture has been a great help in generating interest in the use of the computer by members of that School. Chemistry A researcher in the Chemistry Department gathers data from X-ray diffraction patterns of crystals and mathematically reduces this data to a set of X, Y, Z coordinates of the atoms which make up the molecules of the crystals. This mathematical reduction is done by a series of Fortran programs, each of which feeds its results forward to the next program in the series. Frequent checking of intermediate results enables the user to alter, if necessary, subsequent processing of the data. Such a reduction usually takes about one week using the over-the-counter Table 2 TWENTY GROUPS WITH MOST CONNECT TIME SEPTEMBER 1968 THROUGH JUNE 1969 Group Hours 1.

Using RESPOND, the same amount of work, can be finished in a single afternoon. The job submission feature, which permits complicated sequences of job steps, is particularly useful. The convenience of having the remote console in the laboratory contributes to the savings in time. Curriculum Enrichment Still another application of RESPOND is being undertaken. This application involves giving access to RESPOND and the 6600 system to neighboring colleges and universities. These institutions will use teletypewriters and RESPOND as a means of giving computer access to their students and researchers. Eight schools, ranging in size from 770 to 8500 students, are to participate in this project. These schools are located as far away as 250 mi les from the computer in Austin. Funds for this project are being provided by the National Science Foundation, The University of Texas, and each of the participating colleges and universities. The overall aim of the project is to enrich the curriculum of all the participating schools by supplying both computational facilties and educational interchange. This enrichment of curriculum is intended to affect several academic areas. Zoology In the Zoology Department, researchers have used the computer in several projects including the statistical analysis of data, the simulation of population and genetic evolution, mathematical modeling of plant growth, and ecological studies of population distributions. The use of the computer in this department was stimulated by a graduate student who developed a package of statistical subroutines which are tai lored for use from a remote console. He feels that many researchers now do a better job of data analysis because of the convenient access to the computer provided by RESPOND. Art The Art Department is using RESPOND as a vehicle for handling a large data base made up of information about projection slides. The slide library consists of approximately ninety thousand slides, a number which makes thorough use of the library difficult. Information about the contents of the library is being prepared in a form suitable for machine retrieval. This slide library data base should enable art instructors to easily locate slides which are pertinent to upcoming lectures. The convenience of being able to use a remote console is an important factor in the acceptance of such a system. User Opinions The people who have used RESPOND for the past three years have expressed many opinions about the system. Some of the early users of RESPOND were often dissatisfied with the system, since it often lost their files and was generally undependable. Others discovered that if adequate back-up procedures were employed, they could make effective use of the system. RESPOND has been improved; today, files are rarely lost, and RESPOND is as dependable as other components of the computer system. Many prefer to use RESPOND because job turnaround is much faster than with other methods of computer access. Also, users find that the location of a remote console in a place which is convenient for them, rather than convenient for the computer, is a great advantage. 34 Summary A remote console system, such as RESPOND, offers a reasonable compromise to computer centers that want to provide both an efficient "over-the-counter" or batch service and a remote console service. The remote service 'does require some system resources, but the encroachment on the resources required by the batch service seems to be at an acceptable level. The remote system can efficiently handle many consoles and can satisfy most user commands quickly. The commands which cannot be satisfied can be submitted to the batch input queue for service by that system and the results quickly retrieved. At the same time, the batch system can also process jobs in a rapid and efficient manner. The wide diversity of projects described above illustrate that such a remote console system can be a powerful and flexible method of using a computer. o Appendix A CDC 6600 System-at the Computation Center Characteristics and Configuration Computer Central Processor Central ~1emory Peripheral Processors (10) 3 million instructions per second (approx.) 131,072 60-bit words 1.0 usec. cycle time 4096 12-bit words Data channels (12) Input/Output Equipment Disk Cabinets (4) Tape Dri yes (6) Card Readers (2) Line Printers (4) Card Punch (1) TTY Multiplexer Satellite Computer Multiplexers (2) 80 million characters per cabinet 800,000 characters per second, transfer rate 120,000 characters per second, transfer rate 1000 cards per minute 750 1 ines per minute (approx. ) 250 cards per minute 64 telephone lines (max. ) 4 high speed lines (40.8 KHz) per multiplexer Graphic Display System Microfilm Recorder Operating System Cent ra 1 ~lemory Res i dent Peripheral Processors Disk Storage RESPOND Central ~~emory Disk Storage (User File~ Central Processor Time Peripheral Processors 13,824 words Monitor - 1 System Display Dri ve r - 1 Pool Processors - 8 6 million characters 22,100 words (avg.) 14.5 million characters (avg. ) 4.7 per cent (avg.) 1.5 of 8 available in pool (avg.)

COMPUTERS AND AUTOMATION for March, 1970 WORLDWIDE REPORT FROM GREAT BRITAIN / Attack on the European Bureau Market Three important happenings are putting ICl, Britain's computer "white hope", on the Europe~n map: In reverse chronological order they are: a strong alliance with an American software consultancy group to attack the European bureau market, an agreement with Britain's biggest bank to reinforce and expand ICl's bureau operatio~s at hom~, and participation in an inter-European consortium to bid for space research business. . . Key to the bureau venture is the European subsidiary of Computer Data Systems, a Washington-~ased pr!vate company which was set up in 1968 by ex-Univac senl.or staf!ers including Joseph H. Easley who started the major Univac software project known as "Exec 8". Computer Data Systems Internationr.ll Limited is the new European subsidiary, CDSll for short, and Easley is its president. It has signed an agreement with ICl which will promote both parties' plans to penetrate Europe. CDSll was formed to sell time-sharing services in Britain and other European countries. Its senior staff have been looking at available equipment for many months and finally picked on ICl's 1904A, a machine able to run at least 35 terminals for time-sharing and/or batch and remote batch work. Cost for cost, it has a significantly better performance than the IBM 360/50 and is more suitable for this type of work, Easley told me. However, he said ICl had done all the software except time-sharing and this is what CDSll would provide. Financing The terms of the financial agreement on the venture include a 25 per cent participation in the equity of CDSll by ICl through the purchase at an agreed price of 250,000 shares of common stock. In addition, CDSll gets a contract to develop a time-sharing and communications package for the bureau operation. Both partners are reticent about the amount of money involved but a close look at the equipment it is proposed to instal shows that it is likely to be over the $20m mark in the initial drive. Seven 1904A centres are to be set up, the first in Geneva next May at the headquarters of Cyberna, a 100% CDSll subsidiary, which is already running a small European service on a 1904. Paris and Stuttgart will follow-they are already linked over MDS equipment with Geneva-with Stockholm scheduled for later this year. In 1971, Milan and Amsterdam, as well as london would be added, but there is nothing rigid in this timetable which depends how much business can be won in the various cities involved. Becau~e so few bureau operations have been launched in Europe, in contrast to the U.S. and British scenes, there is every chance of success. The london end of th is operation wi II be closely associated with a new company set up between ICl and Barclays bank, not yet named, and aimed at winning an even larger slice of the booming British bureau business. ICl is putting in all the assets of ICSl, its bureau subsidiary, which now has a turnover of about $15m as well as 1,000 staff and 16 machines. This represents 60 per cent COMPUTERS AND AUTOMATION for March, 1970 of the equity. Barclays-which claims to be the UK's largest bank-is contributing its Customer Services Division and a payment of £ 1112m or $3.6m. .. . The Barclay contribution could be underestimated If It were not for the fact that it has 3,300 branches; one in practically every city, town or major village in Britain. This does not mean that small companies out in the sticks will suddenly flock to the merged ICSl-Barclay bureau. But ICSl's offices and the Barclay branches will be kept in touch with each other by liaison officers and extra business must result. When it is remembered that Barclays uses IBM machines for its london operations and Burroughs in the on-line system it is aiming to bring into operation early next year, the development is significant. ICl so far has had a bare toehold in the banks and that only in the clearing centre for the big joint stock banks, set up in london under the name of Bank Giro. Eurodata Another major piece in this jig-saw is ICl's participation with Olivetti of Italy, AEG-Telefunken of Germany and CII of France in a consortium called Eurodata to bid for contracts to provide computing and communications facilitie.s at three centres of the European Space Research Organization where IBM is strongly entrenched. The're is a European precedent for such electronic collaboration. The big MADAP air traffic control system and the Bretigny air traffic simulator system, both belonging to Eurocontrol, were set up by a consortium of Plessey (U.K.), AEG-Telefunken (Germany) and CSF (France). Even though Eurodata's equipment would come from many sources rather than a single manufacturer, there is pressure for a European "technological renascence" which might easily overcome this difficulty-it would provide a big fillip to standardisation! Contracts may be awarded very soon. More than any other recent bid, this will have stirred IBM's opponents in Europe to action. Meantime, ESRO has a go-it-alone lobby that wants to build its own synchronous satellites and the means to put them into a high orbit. Europe's rockets may be rudimentary, but its computers are not. Success with Eurodata as with CDSll, plus the bureau base and a continued favorable business-the first postmerger year was better than expected-could put ICl firmly on the map of Europe as a major contender to IBM and GE-Bull. There is only one proviso and that is for the next government to leave the company undisturbed for at least five years. Any attempt by a future Tory Governmentwhich we are very likely to get in about 12 months-to withdraw the £ 18m of government money invested in ICl would be catastrophic.

((A II of the developments in the (information sciences' of the last 25 years have had the same kind of interdisciplinary implications ... yet the elements of this synthesis are far too little recognized or understood (even by high-level professionals)) and not a trace of it has yet reached the level of general undergraduate education." There has been much talk, in recent years, of the "information explosion" - the supposedly exponential growth of knowledge at a rate which is forcing us all to specialize ever-more narrowly. However, as Bellman of the RAND Corporation has emphasized, the real problem is not the sheer volume of knowledge, but the lack of new theoretical frameworks into which it can be meaningfully integrated. The problem is especially acute for college students, who are faced with a large number of distinct and seif-contained disciplines, with no attempt whatsoever made to integrate and synthesize them. Yet, as Poincare pointed out in 1900, it is precisely through the integration of disparate concepts that progress takes place. In his words, " ... new connections are constantly being discovered between objects which seemed destined for perpetual separation, scattered facts cease to be irrelevant to one another, and tend to order themselves into an impressive synthesis."l At present there is nothing so important for the intellectual world in general and the college curriculum in particular - as the development of new conceptual frameworks in which this kind of synthesis can take place. Developing New Theoretical Frameworks The publ ication of Norbert Wiener's Cybernetics 2 was quite possibly the most important event of this century, as far as the development of new theoretical frameworks is concerned. Wiener showed that the concept of negative feedback is not limited to man-made control systems, but is also applicable to biological, psychological, and social processes. All of the developments in the "information sciences" of the last 25 years have had the same kind of interdisciplinary implications information theory, general systems theory, modelling and simulation, work on abstract languages, the multilevel system concept, etc. We are at the dawn of what may turn out to be one of the most significant periods of synthesis in the history of thought - yet the elements of this synthesis are far too little recognized or understood (even by high-level pro- 36 fessionals), and not a trace of it has yet reached the level of general undergraduate education. The average student probably thinks "cybernetics" is some kind of Russian plot, if he has ever heard the word at all. (I recently encountered a group of 8 college graduates, all "A" students, all planning to go to graduate school, none of whom had the vaguest idea what the word meant.) Yet it is certainly apparent that advanced thinking in psychology, the social sciences, and even philosophy will be more and more influenced by the ideas of the computer and information sciences, just as in previous years it was so greatly influenced by Newtonian and later Einsteinian physics. (See McLuhan 3 for a fascinating and quite controversial discussion of the nature of this influence.) New World Views in the Curriculum I am arguing, then, that the concepts of the computer and information sciences are sufficiently rich and general to be of interest not only to scientists and engineers, but also linguists, artists, philosophers, and historians. What we are dealing with here is not only a technology, but a Weltanschauung a conceptual system which carries with it, as do all major conceptual systems, a new way of looking at the world. And new world-views are sufficiently rare and important events to deserve a significant place in a college liberal-arts curriculum. A non-specialists' course in computer science, taught with an emphasis on integrative concepts, could be a source of considerable intellectual stimulation to the student. The outlines of such a course are still vague and hazy, because the outlines of our conceptual framework are still vague and hazy. However, in the remainder of this article I would like to jump in and make a specific proposal. A Proposed Course Suppose that we develop a course based around the idea of modelling and simUlation. This course will be de- COMPUTERS AND AUTOMATION for March, 1970 signed for students who may have no previous experience with computers, mathematics, or science. It wi II be designed to give the student an integrated understanding of computers, modelling, and the nature of complex systems. A possible outline for such a course is presented below: 1) The idea of modelling. Drawings, ordinary language, and equations as models. Problems of comparing models with reality. 2) Algorithmic models. Experiments with hand-simulation for simple discrete-time models, such as a simple queueing system. 3) Algorithmic languages. Student is introduced to a high-level computer language (possibly BASIC) and uses it for simple modelling problems. Time-sharing or fast batch turnaround is essential here for quick learning. 4) Models of simple physical systems. Such systems as falling objects, oscillating springs, etc. can be dealt with using simple numerical integration techniques. Of course, no attempt at a formal development of calculus would be made. 5) More complex models, both continuous and discrete-time. Problems of calibration and verification. 6) Modelling in psychology, sociology, etc. Problems of free-will, self-consciousness, reductionism. Special problems of calibration occurring in these fields. (See Winch,4 Wiener,5 and an earlier paper by Robinson and myself6 for a discussion of these problems.) The old question of whether there are general laws of human nature and of history reconsidered in the light of the modelling concept. 7) Models that build models survey of artificial intelligence research. NUMBLES NUMBER PUZZLES FOR NIMBLE MINDS -AND COMPUTERS Neil Macdonald Assistant Editor Computers and Automation A "numble" is an arithmetical problem in which: digits have been replaced by capital letters; and there are two messages, one which can be read right away and a second one in the digit cipher. The problem is to solve for the digits. Each capital letter in the arithmetical problem stands for just one digit 0 to 9. A digit may be represented by more than one letter. The second message, which is expressed in numerical digits, is to be translated (using the same key) into letters so that it may be read; but the spell ing uses puns or is otherwise irregular, to discourage cryptanalytic methods of deciphering. We invite our readers to send us solutions, together with human programs or computer programs which will produce the solutions. NUMBLE 703 HE x THINKS + WHO T H L H MK T MI I 0 Need for Intuitive Presentation • It may seem difficult to believe that this wide a set of concepts could be covered in a reasonable time by students with no relevant background. However, I believe that if the presentation is made intuitive rather than mathematically formal, and if the material covered is tied together by a single unifying concept in this case, modelling surprising progress may be made. I recollect vaguely that some company has experimented with teaching Junior High school students an integrated mixture of calculus, physics, and programming. The programming was used to make numerical solutions to problems feasible, thus avoiding the need to choose between complicated analytical solutions and "cookbook" formula memorization. This project was successful, and illustrates the power of an integrated approach. I think that equal success might be obtainable with the still broader integration proposed in this article. At any rate, it should be most interesting to see what kind of student reaction and comprehension is obtained from a course of the kind outlined here. 0 References IGeneral Systems, Yearbook of the Society for General Systems Re· search (1968), p. 11. ::!Norbert Wiener, Cybernetics, or Control and Communication in the Animal and the Machine (1948). 3Marshall McLuhan, Understanding Media: the Extensions of Man (1964). -1peter F.

Bower Graduate School of Business Administration Harvard University Boston, Mass. 02138 ({The problem of order in society) which was originally conceived as the task of God) and later the task of kings and prime ministers) has now been reconceived) at least partly) as the field of endeavor for a new kind of engineer." YSTEMS ANALYSIS far sacial decisians is a very apprapriate title far the last half af the twentieth century. It captures perfectly what Michel Crazier(l) has described as "aggressive confidence in human reason and in the capacity of America to solve all problems by its use." While Crozier's analysis of the American theme may be somewhat optimistic in its evaluation af the accomplishment of the new methodology, he has captured the goals and philosophy of the current approach in a way that the participating technocrat does not. S dividual and his family living in a city has much to do with whether that city is safe, whether it has high welfare costs, and whether it will continue to survive as a viable and healthy social organization. Two Principal Kinds What my title implies is a fundamental and very modern belief that the tools of quantitative analysis applied to societal problems in their full technological, economic, psychalagical, and political camplexity can resolve what were traditionally viewed first as religious and then as political issues. In effect, the problem of order in society, which was originally conceived as the task of God, and later the task af kings and prime ministers, has now been reconceived, at least partly, as the field of endeavor for a new kind of engineer. The purpose af this paper is to examine the nature and promise of this revolutionary approach to social problems. To do so it is first necessary to examine what is meant by social decisions, and how these decisions are usually made. It is then possible to examine systems analysis as a new approach, consider its worth, and determine what prerequisites must be met before it is useful. It is worth noting that there are two principal categories of social decisions, each of which tends to pose different kinds of problems. There are, first of all, social decisions that must be made by society in one organized form ar another. An example of such a decision is the construction of a giant hydroelectric dam, the provision of electric power, or the development of a transp,ortatian system. So. cieties have always regarded these as tasks which must be undertaken by one kind of organized group or another. In contrast, education, housing, and even public safety have at some points in history been considered as services that individuals can obtain for themselves. The great importance of this distinction derives from the fact that the decision to regard any ane of these latter areas as an arena for social planning implies a political choice to arganize for that purpose. What is then true is that the choice of organizational form may be as important to society as the act of the chosen organization. In short, technology has always forced us to accept some tasks as inherently the object of group effort. Others, because they are technologically capable of being performed by individuals for themselves pose a prior question of organization for society. Social Decisions Ways Society Has Chosen to Organize Tasks A sacial decision in its most commonly understood form is a decision made by society for itself. Examples of such decisions are the choice of a leader in a popular election, and the distribution of rewards and status in a social group. However, this paper uses a wider interpretation af the phrase 'social decisions' - it is used to' describe the decisions taken by individuals or groups that have material effects on individuals other than those involved in making the decision. In the economist's terms, we are talking about decisions with external effects. In modern industrial societies more and more decisions have become social decisions as technology has increasingly strengthened the web of interconnection that binds one individual to another. Examples of this phenomenon are numerous and certainly for this audience it is not necessary to state them at length. The problem of rationalizing and humanizing the urban environment is one such issue. How to provide the cleanest air, comfortable housing, convenient transportation, and good education for millions af people gathered together in cities is a problem we have not yet resolved. I n a way, each part of the urban problem, environmental pollution, housing, transportation, and education, represents a problem of external effects. Viewed in its most threatening aspect, the life available to each in- The implication of this distinction is that many of what we regard as culturally derived social institutions in fact represent choices concerning the mode by which, and the direction in which, social resources will be allocated. Public schools, cemeteries, narrow winding roads and superhighways, airports, and universities are all examples of this proposition. These institutions represent ways in which society has chosen to organize for its tasks. Implicit in the notion of calling these arganizations the results of social decisions is the idea that there are or were alternatives to the particular choices that were made. The existence of alternatives is important because it raises sharply a new distinction, that between means and ends. Many political and social institutions that often regard themselves as social goals in and of themselves were created as means to achieve separable end objectives. The Problem of Order in Society 38 Education As an example, let us look at an area that has been handled most traditionally to see what kind of alternatives are available education. To begin with, the education of children could be left to the process of experience, although parents have almost never been willing to allow COMPUTERS AND AUTOMATION for March, 1970 their children to grow up without any of the benefits of their own experience. Even animals seem to insist upon family education. An alternative to the family is the private tutor. Beyond the tutor are various forms of private schools, and various arrangements of educational curricula. For example, most children can be given a basic education and then turned out early to society to work for an elite who progress to graduate education. Or as seems to be the case in America today, a majority of the population can go on to university education. Curricula can be either general or specialized. Training can be academic or vocational. The technology of education can be varied substantially. Today the various available pedagogic devices range from the face-to-face discussion of tutor and student to the lecturer addressing an audience of 1,000, to the pupil before his programmed teaching machine, to the student working in a laboratory with little guidance, to discussion groups, and finally to correspondence courses. All of these devices represent alternative ways of educating men to lead individually and socially useful lives. Scarce Resources The very thought of choosing among these alternatives raises a second important aspect of social decisions. Almost always the resources that have been allocated in one way or another are scarce; that is, it is not possible most of the time to resolve a decision as to how some end of society shall be achieved by pursuing more than a limited number of alternatives. Apparent in this observation is another implication of the concept of social decisions. As soon as one thinks of some aspect of society as a social choice to allocate scarce resources in a given fashion in order to meet a given objective, it is immediately obvious that these resources might be used to achieve other objectives as well as achieving the same objectives in different ways. So that one not only has to think of how given educational objectives will be achieved but also of the possible relations of housing or transportation to education. The Traditional Approach to Decisions One question that is of immediate interest is the somewhat skeptical inquiry, "It's all very well to say that the notion of taking social decisions explicitly is revolutionary, but we have been making social choices for a long time. How does the implicit process work and what is wrong with it?" In the normal course of events, the issues we have raised are shaped by a variety of policies. The principal difference between the decision process when viewed systematically as a social decision and traditional methods is that traditionally policy is an outcome. Policy is something decision makers use to explain a sequence of events after the events have happened. In every nation there is a variety of institutions that have evolved historically to carry out some set of specified tasks. The military is charged with the defense of the nation, the postal service with delivering mail, the medical profession with the health of the citizenry, and the police with public safety. Over time, as new tasks arise, they are assigned to newly created organizations or added on to existing ones. For example, in the United States the turbulent thirties saw the creation of a host of new government organizations. But, in some cases, they were set in very surprising contexts. For example, electric power in the United States was principally the responsibility of the Department of the Interior. But because President Roosevelt did not trust his Secretary of the Interior to carry out his rural electrification program with sympathy, it was placed under the Department of Agriculture. COMPUTERS AND AUTOMATION fOT March, 1970 Self-Preservation of Organizations Added to the often haphazard evolution of the agencies and institutions that serve the needs of society is the phenomenon best studied by Professor Parkinson, the insitutionalization, and then bureaucratization, of organization. Units created to serve even temporary needs have a way of finding new tasks for themselves, in effect, making themselves permanent. It does seem clear that the true end of any organization is its own self-preservation. Budget Changes The problem is even worse, however. One of the most unvarying findings of the emerging research on organizations is that, except in time of revolution, no organization permits a decrease in its budget save by some small increment. Existing organizations are always fighting for their share of the pie. Even in time of stress when their own need is of somewhat lower priority, they wi II resist cuts in their budget. In times of abundant resources they will also resist increases in other's shares of the budget much beyond their own. Implicit in this characterization is the argument that in normal process of using resources consists of giving each agency of government and society roughly the same portion that they had in previous periods with only minor adjustments. And such is the fact. However, over long periods of time, radical shifts do take place some sectors rise and some decline. But the trend is slow and primari Iy responsive to the power of the organizations in question. It is common to see institutions of society resist recommended change coming from seemingly all-powerful sources. Policy the Result of Bargaining Let us see what this means in summary. The assignment of a particular task to a particular institution in society is historically often a matter of accident. Over time, institutions created for one purpose acquire others. Finally, institutions once created seldom die and seldom give up their share of society's resources over any short period of time. Hence, at any point in time when an issue arises, the way in which the decision is made determines what policy will be. The decision that is made is almost always a resultant of bargaining among the agencies and departments that feel they have an organizational stake in the issue at hand. Public Health This is particularly true when we talk of the broad, sweeping social problems of interest in our nation today. Let us take as an example the problem of public health in its institutional setting in the United States. Of critical importance to any medical problem is the community of medical practitioners - the doctors. These men acting individually and through their organization, the American Medical Association, take supposedly objective expert stands on all issues affecting organization for the provision of health care in the United States. As revolutionary a bi II as the Heart, Stroke, and Cancer amendment (which asserts the right to adequate health care for every citizen in the United States) has in its preamble a phrase to the effect that the sweeping programs contemplated under the act wi II be carried out subject to the caveat that "the traditional doctor-patient relation will not be changed." In other words, the doctors have a great deal to say about how society organizes to provide health care. But also involved in any health problem is the US Public Health Service and its constituent agencies, the National 39 o Institutes of Health, the National Institute of Mental Health, the Bureau of Health Services, and the Bureau of Health Manpower. In addition, involved with the provision of health service is the Social and Rehabilitation Service Agency, including the Children's Bureau, as well as the Social Security Administration. But we are not through, for the Department of Defense and its four branches spend over $1 billion for health related activities, the Veteran's Ad· ministration spends over $1 billion, and five other agencies of the government spend more than $50 million each on medical and health related programs. When we remember that medical research is conducted principally in the universities and the drug and chemical companies of the country, the complexity of the field is obvious. The point is that any set of activities in the health arena in the United States represents less a policy designed to cope with a set of perceived issues and much more the combined momentum of the assorted agencies active in the health field. Historical Accidents One could go on with examples, if one liked taking one's cases from the problems of other nations. But there is no need for that. We can agree that usually it is purest accident for the particular institutions that have developed historically as responsible for a set of tasks to address themselves to the full consequences of a major new problem facing society. They are simply not organized to do so because it was not their job at the time that they were created. If a railroad was established to supply passenger transportation between two points, it is unlikely that a century later the organization designed to run that railroad will be adequate to the task of planning urban transportation. Nor will the combined efforts of motor car companies, highway commissions, railroad managements, and air transportation boards acting separately provide any more coherent a policy. Nor will a joint committee of this group. Only a single vast entrenched institution, with no competition, that believes that it fully understands the new problems is worse than the usual fragmentation. For instance, take the situation in the field of education in most countries, where an enthroned establishment constitutes an insuperable obstacle to systematic social choice. Systems Analysis: Planning-Costs-BenefitsAlternatives What, then, is the alternative to the existing process? It is the basic process of planning as it has come to be understood in military and industrial organizations. This process consists of specifying long-term objectives and values, evaluating in terms of costs and benefits the alternate routes to the achievement of these objectives, and choosing among the available alternatives the course of action that will best exploit present and potentially available resources. Systems analysis, despite its aura of sophistication, is really no more. It is true that systems studies often involve models, and almost always emphasize quantitative analysis. But a model is merely a very specific way of expressing a system of relations for the purposes of analysis. Models are useful for clarifying the cause-and-effect or input-output interactions that characterize the elements of a problem. And the use of quantitative analysis is less a reflection of the measurability of the operative variables in a social system and more a testimony to the usefulness in analysis and communication of the commonly understood assumptions underlying the language and logic of arithmetic. 40 Specifying Goals Despite the simplicity of the planning format, it is possible to draw strong prescriptions for the social decisionmaking process. To begin with, the process of specifying goals implies that each major decision to commit resources requires a reassessment of objectives. Rather than regarding any action as an occasion for the extrapolation of some institutional founding father's intent, objectives must be tested for completeness, consistency, and relevance. Administration of Welfare It is not unusual for an organization to find its conception of purpose lacking on all three counts. For example, standards of fairness, efficiency, and accountability often conflict directly with the achievement of purpose. The administration of welfare in the US is a classic example of a program that defeats its own ends through its pursuit of short-run equity in the redistribution of income. In order to avoid using taxpayers' money to subsidize fully families already earning a partial income, the welfare administration designs and policies actively a system that encourages husbands to remain 'unemployed and to desert their families. During the 1930's the clientele of the administration was such that the rules might have achieved a kind of equity, but in the 1960's the system exacerbates the problem it is designed to cure. Bureau for Fair Wage Standards Another instructive example is available in the bureau responsible for enforcing fair wage standards. It was found when they were asked to examine their objectives that they were oriented through their internal performance measurement system so as to consider organizational success to be a high number of complaints received and resolved in favor of the complaining worker. They had lost almost all interest in any steps to achieve or measure over-all compliance with the fair wage law. Evaluation of Goals In short, institutions making social decisions will often find that society has changed, leaving them less relevant and less useful than before. Evaluation of objectives in planning will protect the organization from obsolescence. It will also protect it from the penalties of incompleteness. Moreover, an understanding of the multiplicity of objectives that an organization may serve will keep it from ignoring distributional and process effects. In social matters, one man's benefits are often another man's costs. Care must be taken in establishing goals to see that aggregate goals are not achieved through unintended individual costs. This kind of examination of prior goals - both long-run objectives and standards of process - is absolutely critical, for it leads to the discovery of the integral relation of the ends of society, and the means of achieving these ends. The fact is that, except for a very religious or otherworldly minority, most of us are interested in the state of affairs along the road to a better world, as well as the attributes of that better world when we get there. Frequently the choice of ends must be determined by the availability of acceptable means. Relation to the Environment Having determined the basic goals that will structure analysis, attention must be given to the nature of the COMPUTERS AND AUTOMATION for March, 1970 organization and its relation with its environment. It is particularly important to understand where the boundaries of the unit are, how the subparts of the unit operate, and how this system interacts with the environment. An example is available in the plight of a Boston businessman who tried to provide better jobs for negroes by hiring them in his company. He found that they could not get to his place of work in the suburbs because they lacked the proper transportation because they could not afford automobiles; they could not afford automobiles because their jobs were poor; their jobs were poor because their education was poor; their education was poor because they lived in the ghetto; and so on. For his purposes, the whole city was the relevant system. On the other hand, for some purposes - perhaps public health - he might have found that he could operate on only one part of the city with satisfactory results. The point is that the definition of the relevant system varies with the problem under consideration and the goals of action. It is important in looking at the environment to determine what opportunities it offers for progress toward basic goals, what threats are posed by hostile forces, and what risks are associated with various lines of action. For example, there are those in the United States who for years have argued that a stable monetary policy implied higher rates of unemployment than would be necessary if a slow degree of inflation were tolerated. They argued that the concentration of unemployment among certain obvious minority groups was so debilitating to society that the cost of inflation was worth bearing in order to reduce unemployment. A good many policy makers who objected to this argument may have reevaluated their position in the flickering light of burning cities. Limited Resources At least as important to the planning process and a systemic view of an organization in its environment is a consideration of opportunities in terms of organizational resources. Useful planning begins with the recognition that all goals cannot be achieved at once. Beyond the fact that some may be inconsistent, it is also true that agreed upon benefits generally entail costs and they cannot be borne without limits. In order to permit a careful consideration of alternative uses of resources, the pursuit of each of the several goals must be specified in a series of alternate programs. By a program we mean a timed sequence of moves that commit resources in a purposeful fashion. When this stage in planning is completed, it is possible to contemplate an array of alternate programs that, to a greater or lesser degree, contribute to fulfilling a list of objectives. It is then possible to assess these alternate programs in terms of their relative costs and benefits. While measures of cost! effectiveness do not constitute a pol icy, they permit a much more informed choice of program. At this point in the analysis it is also important to recognize that an instrumental view of organization is implied. That is, it is assumed that the choice of goals and programs to achieve those goals will provide criteria for the structuring of institutional arrangements, the design of information systems, and the design and management of systems of motivation and reward. Where these structural phenomena are not available as instruments to the problem solver but, rather, are constitutionally given, then they must enter into the analysis as important constraints on action. In either event, alternative programs must be judged in terms of their organizational consequences as well as their economic costs. COMPUTERS AND AUTOMATION for March, 1970 Administrative Feasibility What emerges from this pattern of analysis is a concept of administrative feasibility. Some programs, attractive to technically oriented specialists, must be discarded because the administrative problems they raise are such as to make the programs too costly or infeasible. The goals involved must be achieved by some other route. Alternatively, a pet program of the administrative type may have dramatically excessive economic costs. At this phase of the planning and decision making process, what is properly called systems analysis is complete. The pursuit of objectives has been clarified by considering the alternative approaches to applying resources in the context of the entire relevant set of institutional, technological, and environmental relations. Political Issues Again, it is important to realize that no choice is implied by this analysis. Rather the analysis informs the judgment of decision makers by illuminating the question of how resources may best be used to attain a set of objectives. This 'how to' decision is substantially different from the decision 'should we.' Some of the most dramatic political conflicts associated with the application of systems analysis in the United States arose not because of the 'how to' analysis, but because the 'how to' analysis was used to serve a particular set of political interests involved in the decision 'should we.' Instrument of Social Change It might be well to state here at an early stage in the evolution of the use of systems analysis that the 'should we' question is almost always a political one. I disclaim a belief that systems analysis will resolve the basic social questions of society; but there is some evidence that systematic analysis of social questions can help decision makers make better choices for society. It cannat be denied that by this mechanism systems analysis may be an instrument of social change. Certainly by providing an alternate to the mechanism of institutional bargaining described above, systems analysis is a threat to those who have a purely structural stake in existing modes of decision making. Moreover, where there is an agency or department with a fundamentally valid capability to operate in a particular sphere, systems analysis may provide precisely the lever that can free capable experts from the shackles of bureaucratic tradition. Example: Education in Philadelphia Two examples of the application of systems analysis may be instructive. The first is the project of a local government in the field of education, the second a study performed for a state government in the field of information storage and retrieval. Education was chosen for one example because it is a field in which the entire population is involved, experts disagree on all major issues, all sorts of types regard themselves as experts, and measurement is very difficult. On the other hand, in principle, information storage and retrieval is a nearly technical subject, involving few political problems. The site of the systems study in education is Philadelphia (my account is based on references 2 and 3). It originated in substantial dissatisfaction with the local public school system on the part of a small group of businessmen. They provided the impetus and continued political support for a new Superintendent of Schools. He took over a system with no plan beyond one year, with no priorities among goals, with a budget arranged to 41 control items such as pencils and salaries, with none but political measures of performance, and a structure that left virtually complete control over school programs and curricula in the hands of a School Board of teachers and laymen but no professional administrators. The first steps taken involved establishing a planning office reporting to the Superintendent and introducing a planning, programming, and budgeting system. Broad fiveyear goals for the school system were provided by a newly constituted Board of Education. The means by which each school district carried out the goals of the Board were called programs and activities (subprograms). In 1967 there were twelve programs such as "Early Childhood Education," "Senior and Technical Higher Education," and "Community Education." They were formulated so as to facilitate relating program planning to financial budgeting. The budget, in turn, was a program budget: a listing of proposed expenditures by program-goal categories rather than objects of expense. In a program budget system, financial budget elements are arranged primarily in terms of the benefits expected from expenditures, and only secondarily in terms of input. For example, an 'output' of an elementary program would be boosting student skills in reading or arithmetic, an 'input' would be a specified number of teacher aids at a specified cost. In 1968-1969, the Philadelphia effort also began to introduce ways of measuring the benefits of programs as a method for altering the allocation of resources among programs. Moreover, an attempt is being made to convert to a system of managerial accounting using an accrual concept, rather than the traditional cash-expenditure method. As a result of the systems study by the planning office, it was recommended that these planning and program goals be served by a second major step, a decentralization of decision making in the system. Finally, an educational information center has been proposed to provide control for the Superintendent over the activities of his system and its relations with its public. The skeptic will say, "These are all promises for the future, and besides what contribution has be"en made by systems analysis." The latter objection has already been considered indirectly systems analysis is merely a convenient phrase for systematic purposive planning. The contribution of planning in Philadelphia is clear: it has indicated how limited funds can be used to improve the quality of the city's public system of education. (The cynic will say "Have you changed the teachers?" The answer is that the system they work in is being changed for the better without strikes or riots.) As for the prospective aspect of these gains, the existence of a five-year plan has permitted the creation of a capital budget. Proposed for the period 1969-1974 is a $489 million construction program involving 67 new schools and 38 other projects. The plan takes into account new demographic physical planning standards, revised curricula, new concepts of architectural design, and goals for racial integration and community development. An advisory committee of businessmen has aided in planning the program to finance this renewal of the city's schools. To put this program in perspective, of 245 schools in 1968, 54 were built prior to 1906, and another 67 were more than 40 years old; 54 per cent of the elementary schools, 84 per cent of the junior high schools, and 78 per cent of the senior high schools were considered overcrowded. A high percentage were racially imbalanced. If all systems analysis did was serve as catalyst for the response to the situation, it would have proved itself. If it turns out to have guided the use of resources wisely, it will have made a truly remarkable contribution. 42 Example: a State-Wide Information System When we turn to the study of a state-wide information system, the story is both briefer and more ambiguous. The Lockheed Missiles and Space Corporation, at the invitation of Governor Brown, conducted an over-all study of the information requirements of the state and local governments of California. On the basis of both present uses and future projections, some conclusions were reached about the nature of information flow in California; for example, extensive flow exists among state-level organizations, but local governments are the largest collectors of information, with a heavy flow of data moving upward from local to state agencies; electronic data processing is growing widely and rapidly at state and local levels, with a large potential for duplication of efforts. "The study team demonstrated the feasibility and desirability of a state-wide information system and recommended the evolution of a federation of information processors and users. Geographic centralization of organizational files was not recommended, nor was the rigid restructuring of existent files.(4)" The recommended system would allow various State and local agencies to remain autonomous and independent; they would be required only to maintain standards of compatibility so that information exchange would be possible. The recommended system was estimated to cost $68 million over 10 years to develop, and $13 million annually (after 10 years) to run. Savings through mechanization and elimination of duplication were estimated at $116 million annually. In all fairness it should be added to this report that one expert commentator described the study team as "information technicians [who] mistook their own ignorance for objectivity, and never knew when they were retreading worn ruts . . . Many recommendations turned out to be commonplace or common sense . . ." But, the same commentator noted "first and foremost, the systems approach ... enables the government planner to examine questions implicit in many of the problems [he faces] but never openly addressed in a political and bureaucratic contest." (;")) Prerequisites for Systems Analysis What can we conclude from these two examples? Beyond what we have already said, we learn primarily that there are political, technical, and organizational prerequisites for successful application of systems analysis. By a political prerequisite we mean that, in each of the two instances cited, and wherever success is expected, it is necessary for the political leadership to support the analytical innovation. For a systems study to be successful, it must serve, in an objective fashion, the legitimate leaders of the organization in question. Moreover, those performing the study must understand the political content of the problem they are analyzing. In the arena of social problems, much that the systems analyst desires to change is part of the constitutionally given political structure. While it is possible that elements of the structure can be changed so that, for example, authority resting in one political unit can be transferred to another, the analyst must be aware of these issues as he proceeds to study the problems of a system from a functional point of view. Moreover, the results of systems analysis tend to be long-range programs. Usually political tenure does not coincide with the duration of such efforts, and thus planning and funding cannot be guaranteed. In some instances, because the time horizon of the planner and administrator diverge, the best solutions to be derived from systems analysis may in the short run be politically unproductive. COMPUTERS AND AUTOMATION for March, 1970 PROBLEM CORNER Walter Penney, CDP Problem Editor Computers and Automation PROBLEM 703: TOURNAMENT TURMOIL "Are those the pairings for the big Kriegspiel tournament you're working on?", Joe asked, seeing Pete bent over a sheet full of 3x3 squares. "Yes, and I think I'll have to write a program to work it out," Pete said. "Every time I try to do it by hand I end up with someone playing the same opponent twice, or never being referee, or something." "Shouldn't be much of a job to do by hand. Aren't there only nine of us playing?" "Right, but the boss wants this to be a sort of mixer to get everyone acquainted. He wants everyone to come in contact with everyone else in some capacity either as opponent or referee." "O.K. You've got nine people. Three games can be going on at one time, with two people playing and one acting as referee. It should take only four rounds for everyone to have been in a game with everyone else." "Yes, if it's properly planned." The furrows in Pete's To implement such a result would call for statesmanship of a high order. Where such statesmanship is not forthcoming, the systems analyst ought to be able to produce secondbest, but politically feasible, alternative programs. The second prerequisite for a successful systems study is technical, because there must be substantive contributions available for systems analysis to be useful. If, as in the field of community development, the basic problems have not been thought through and resolved, then what is needed is basic research and not elaborate analytical studies. Organization Finally, organization is a key prerequisite. The study of a state-wide information system was one of four commissioned by the state of California. It was found that many agencies of the state government lacked the capability to monitor contracts, to guide the progress of analysis, or even to evaluate the results. More of a problem, perhaps, was the fact that in some agencies there was no one who could or would make use of the analysis. Sometimes this problem extends to entire departments of a government system. It is also true that, throughout a systems study, continuous coordination is necessary among all who will be involved in its conclusions and whose support will be needed if they are to view it as an opportunity and not as a threat. This is also a problem for the systems analyst and for involved parts of the government, both of whom typically lack experience working with the strange sort of creature that the other represents. One aspect of this problem is that language is a barrier. Systems analysts have a great desire to talk a jargon all their own regardless of how strange or even how irrelevant it sounds to outsiders. On the other hand, public administrators are certainly not guiltless in this regard. COMPUTERS AND AUTOMATION fOT March, 1970 forehead deepened. "But I haven't been able to figure it all out.

Conclusion All these problems are difficult to overcome. But when these prerequisites are satisfied or even where they are only partially satisfied, the evidence available at this time is that the conduct of systems studies contributes more than the exhilaration of an exercise in logic. Rather it makes a substantial contribution to the intelligent use of society's resources. It does this either by informing and providing insight to those who will continue to use judgmental methods of decision making, or it helps by providing the framework both for a system of planning and budgeting and for reorganizing the resource-allocation process. In either way, systems analysis can help make social decision-making a reality. By doing so it gives us some promise that ways will be found to reduce and then perhaps resolve the complex web of problems that encumber modern industrial society. D References 1.

In the same way, a bridge engineer takes a professional responsibility for the reliability and significance of the data he uses, and the safety and efficiency of the bridge he builds, for human beings to risk their lives on. Accordingly, this department of Computers and Automation will publish from time to time, articles and other information related to socially useful input and output of data systems in a broad sense. To this end we shall seek to publish here what is unsettling, disturbing, criticalbut productive of thought and an improved and safer "house" for all humanity, an earth in which our children and later generations may have a future, instead of facing extinction. The professional information engineer needs to relate his engineering to the most important and most serious problems in the world today: war, nuclear weapons, pollution, the population explosion, and many more. NATIONAL GOAL SETTING AND PLANNING Thomas J. Watson, Jr. Chairman of the Board International Business Machines Corp. Old Orchard Rd. Armonk, N. Y. 10504 ((We have littered the last decade with the bones of good intentions) and we've come out disillusioned and angry. With today's rapid communications and computer abilities) it is becoming possible to test alternatives-to know if a program is workable and to get some feeling on what its real costs will be before we commit this enorm01lS nation to an unrealistic or incomplete goal." I want to talk to you about an obscure but important problem of the times in which we live. It's not a very much noticed problem today, but it is a problem which if neglected in the future could cause our country really major difficulties. Ten years back, in the twilight years of the Eisenhower Era, I served with some very distinguished Americans on a committee called the Commission on National Goals. Some of the names of the members are still familiar: Frank Pace, John Gardner, Clark Kerr and August Heckscher. Our job, back in the late 1950's, was to suggest goals for our country in the 1960's, and two things surprised me at the time. First was the realization that this country had no specific goals set down on paper; and second was the realization that no matter what goals we chose, there was practically no mechanism in government to methodically implement them. And there isn't now. Of course, we had the Bill of Rights and the Constitution, -and these in a sense are goals, but they are very broad and subject to various interpretations. We were not suggesting by our efforts that these documents are not the very roots from which this free country grows. We just thought that the complexity of the society demanded more specific targets. The nation was bouncing along as it is now, geared to annual appropriations by Congress, in about the way it had in the 19th century. There was no road map, there was no one to say - here's where we are, here's where we want to go, and here's the route to get there. In 1952, I was made president of IBM. Then we, too, operated from year to year, and in 1952 the hope of our future was the electronic computer. We began to increase our research and development expenditures substantially, and suddenly for the first time in many years, we showed 44 no net increase in profit for that year over the previous one. A terrible shock; an obvious lack of planning and control, but we learned our lesson, appointed a director of budgets, made other changes and we haven't made that error since. We run our corporation in balance. In most businesses, and certainly in highly technological industries, the United States has learned how to set fairly precise goals. We've learned that we have to implement them, step-by-step, in a disciplined way over a long period of time. I believe that the complexity of our modern economy demands national goal setting and planning closely paralleling that which is commonplace in industry. The Decade of the '60's Looking at the goals we named a decade ago and reviewing what actually happened is interesting. The nation did aim toward many of those recommendations in the 60's. We saw vast increases in higher education, for example, and enormous growth in our economy. Our Commission really didn't set these goals and identify them to the country for the first time; rather they are implicit in the we merely emphasized them. But we United States missed some of the problems of the times. Pollution, for example, did not get much attention and we were overly concerned about others, like Appalachia as a specific area of poverty, rather than a country-wide condition. And our call to stop communism anywhere despite the price - drifted us into an unattainable goal in Vietnam. Since we have no formal mechanism to study, adjust, and reset our national priorities in an integrated fashion, we pursued the Vietnam goal to a costly point. The lives of 40,000 of our men have been lost, vast resources have been wasted, and the morale of our youth eroded. COMPUTERS AND AUTOMATION fOT March, 1970 Recognizing Goals Money Is Not Enough This and other lessons convince me that we must recognize the existence of national goals. They are not formally set, but they are there nevertheless. Today, they are a mixture of party platforms, State of the Union messages, and editorial nagging from it all comes that elusive thing called public opinion, and from public opinion comes direction. Since we have goals, even though they are raggedly cast, there is every possibility that the country will pursue them. It follows that we ought to be in dead earnest about setting them. Tomorrow's tragedies as well as tomorrow's triumphs come from today's goals. The national goals of this country should be set and restudied annually. They should be costed and readjusted on an integrated basis just as a larger industrial enterprise sets and controls its goals. This process cannot come about by the periodic appointment of National Goals Commissions like the one I served on. What we need is a completely new governmental body; perhaps a Senate/ House/Citizen group, to sit permanently on this matter and report to the President. Congress would have to pass enabling legislation giving this commission substantial power if it's to do the job that's needed. For instance, I believe we can pour as much concrete as we want to pour in this country. If we're serious about rebuilding the cities, they will be rebui It. If we're serious about cleaning up pollution, Manhattan will have Hudson and East River swimming clubs by 1980. The failures of the 60's were not entirely for want of resources. Whi Ie defense took 37 per cent of our new money, health, welfare and education got over 40 per cent. The failures stem from different reasons. Let me mention them, for I have come to believe that they are ingrained in the way we manage our national affairs. Money is essential, but it is no longer enough. A major shortcoming, I believe, is that we don't take into account the differences between a fully utilized economy and an economy where there are slack and unused resources. Essentially, throughout the late 60's, the U.S. was an economy running beyond safe limits, and it is likely to be running flat out through the 70's. When that is the situation, a government program which pours money into one section of the economy does not call forth unemployed labor or idle plants; there aren't any. What it does is reallocate. It takes from one part of the economy and gives to another. I don't believe this was understood, for instance, when Congress passed the Medicaid bill. Medicaid essentially gave one group, and a very deserving one, the purchasing power to compete for an already scarce resource, health care. Medicaid did not build more hospitals, it did not train more doctors and nurses. It did not, so far as I know, even do much to impact our worst medical shortcoming, the high infant mortality rate in this country one of the highest in the developed world. I don't think the current result should be too surprising spiralling medical costs as the public sector bids against the private for an inelastic supply. I'm sure this was not understood when our legislators, with the very best of intentions, voted for Medicaid. I use it to illustrate a point about goals. In the new and complex economy, without the luxury of idle resources, one goal diverts resources from another, and we have to factor this into the decision making. Economics There's another lesson from the 60's which is basic in talking about the coming decade. We have learned something about economics in recent years. Depression is no longer inevitable; in fact, we can look forward to rapid and fairly steady economic growth if we are wise in the way we manage the economy. This is essential to our national goals. We can have more resources we can do more. A reasonable estimate for ten years from now shows a $1.5 trillion economy, in today's dollars, a per capita income that has grown from the $3,140 of today to $4,370, and government revenues, Federal, state and local, that will have grown from $303 billion to half a trillion. The resources will be there, but what are we trying to achieve with them? Are we still aiming at eliminating communism? Well, we'd better think again. It's a happy comfortable thought to believe that we can indeed make ourselves relatively safe and the Soviet Union relatively unsafe with anti-missile missiles and so forth. But think a little deeper. Our efforts might leave 50 million survivors here at home instead of 25 when the holocaust is over, while we kill two-thirds of the Russians instead of only one-half. This, to me, is only half thinking and, if we set our national goals on this basis, we'll be following an impossible path. If I'm correct then, one goal which we should have in our minds for the 1970's is a more relaxed attitude, a detente, if you will, toward the more tractable communist countries. The most important national priority is first reaching some kind of arrangement with the Soviets. A lot is riding on those negotiations that began in Helsinki. If they fail, the 1970's will tend to be a replay of the 60's, with defense absorbing a goodly share of the new resources we generate. COMPUTERS AND AUTOMATION for March, 1970 Balance and Compromise Just as General Motors can't develop two new Cadillacs for 1971, so the U.S. must balance and compromise toward an integrated set of goals and accomplishments. If health care is not adequate, then the first step should be training doctors and nurses; the second is bringing into the system people who have been neglected. I don't object to seeing both of those steps carried out simultaneously, but, as you know, the step that we took was the second one; and the first one still hasn't been attended to. We're undertaking change through the instrument of government on a scale of vastness that we never even contemplated before. We're trying to get the results of detailed planning without the discipline of planning. Currently, we're talking about a dreadful housing shortage which will increase during the 70's. I see little evidence that this is reflected in increased enrollment in architectural schools, in vocational schools, in new approaches to zoning and land condemnation or in relaxation of building trades' work rules. We have to understand that if you want another 26 million housing units by 1980, a lot has to happen in 1970, and I don't think that it is. We have littered the last decade with the bones of good intentions, and we've come out disillusioned and angry. Just as we've learned something about economics, imperfectly, but something, we have the beginnings of a science of input/output analysis. We're beginning to understand how parts of the economy interrelate, how things fit together and affect each other. With today's 45 rapid communications and computer abilities, it is becoming possible to test alternatives to know if a program is workable and to get some feeling on what its real costs will be before we commit this enormous nation to an unrealistic or incomplete goal. PUNCH LINES . . . People Resources Less developed, but becoming feasible, are some new ways of understanding our people resources; and we know that people are not infinitely versatile. A bond trader makes a very fine executive, but so far not one of them has done much in nuclear physics. To what degree can we shift? To what degree can we find people to take on new tasks? That, I believe, is our greatest constraint, and it isn't considered very often. As I said earlier, if we're going to get these problems solved in the future, goal setting and goal analysis has to be elevated in government. Presidential commissions aren't enough, and we've got to get started. In the final analysis, it's not really hard to set most of our goals education, health care, a decent standard of living there's nothing very complicated about what we want. It will be harder to decide on priorities, but that's what the political process is all about. The real gain, if what I'm suggesting can be made to work, is quite different. The debate about the priorities could be limited to the possible, and the trade-offs, which are mostly ignored today, would be understood. A new Congressional program offered to the country as a Congressional bill would have to be integrated to the overall goals and priorities of the country before being presented to the public, and its impact on all of the other programs would be presented at the same time. Acknowledging Success Finally, I believe we should begin to acknowledge our successes. One by-product of the way we manage today is the endless dialogue of despair. Well-intentioned people believe the only way the national dinosaur can be moved is by noisily kicking it. Their criticism is magnified in minds less experienced and less aware of where we've come from and where other societies are now. The result a rejection of increasingly is nihilism in the young America without any appreciation of what it is achieving. A permanent goals body would not only set the goals - it would report progress and achievement. As an institution begins to grow, it must change the way it manages its affairs. This is true in business, and it's no less true in government. Without goals, explicit goals, and plans for getting from A to B we don't know where we're going, and we don't know whether or not we'll have the resources .to get there. Without goals, follow-up and critical analysis, there is no way to monitor and to evaluate, to distinguish between good management and bad, to distinguish between programs that are succeeding and programs that are failing. And without goals, we have few triumphs, few reasons to say, "This is what we've decided to do, we've worked hard, and we've sacrificed to do it, and here, world, we've succeeded." It's a sad thing, a very sad thing when a nation like this one has to creep into a new decade with its tail between its legs. I don't want to do that again. I want to sail into the 1980's - and I want to see flags flying and hear bands playing. We can do that, I'm convinced, if we're willing to take a hard, cold and constant look at how D we're running the biggest enterprise in the world. This article is based on remarks Mr. Watson made on January 7, 1970, at a meeting of the Bond Club of New York. 46 The computer is really a great big logic machine. It's a machine that helps us reason. And that is why, not because it is a big calculator, but because it can help us reason, I believe we are at the threshold of a real revolution in the way society and man can conduct themselves. -Robert B.

IBM has cut the umbilical cord; the user must become more independent of his vendor. He must learn how to reduce his price increases through careful planning, training, and careful selection of alternatives for outside services. -Paul D. Oyer, President Oyer Professional Services, Inc. 369 Lexington Ave. New York, N.Y. 10017 During 1970 and 1971, separate pricing will have an increasingly beneficial effect on all proprietary software which, while it currently only totals some $30 million of the estimated $4 billion software industry, will triple to $100 million in 1971, reach $2 billion annually by 1975, and $5 billion by 1980. It is doubtful that IBM's share of this market will exceed 40%, with the remaining 60% being split up by other hardware manufacturers and independent software firms. -Dr. Walter F. Bauer, President Informatics, Inc. 5430 Van Nuys Blvd. Sherman Oaks, Calif. 91401 The idolatry enjoyed by the early computers during the 1960's was perpetuated by a generation of users who had, to a great extent, participated in the painstaking creation and refinement of the product. But soon we will have a whole new generation of users who have actually grown up with the computer, and to whom it is as commonplace as the telephone and all other mechanical and electrical devices available to serve their needs. This new wave of computer personnel, unharnessed by false idolatry, will more readily address themselves to greater, more meaningful applications in this new decade. -Isaac L. Auerbach, Pres.

FRANCIS HOSPITAL COMPUTERIZES ITS MEDICAL LIBRARY The St. Francis Hospital medical library in Wichita, Kansas, is believed to be the first medical library of its kind to make "automated" reference material available on a 24-hour basis to every physician. Whereas physicians normally spend hours researching medical journals, they now can see, in less than two seconds, what journal articles are available in the 1 ibrary on a given subject. The St. Francis system uses a partial generic key search technique which enables approximatelypresented or vaguely-known titles· to be found instantly. A videoterminal, located in the hospital's medical library, is wired into the insti tution' s computer systems. Presently, 7500 medical subj ects are on-line in the computer. A companion computer storehouse contains specific listings for each medical subj ect as they are catalogued monthly in Index Medicus and the annual Cumulated Index Medicus. At the time of its inception, January 12, the computer contained 4,482 articles from roughly 100 selected journals for a two month period of 1969. In six months, the computer will contain 1968-69 categorical listings as they appear in Index Medicus. Ultimately, it will carry a complete listing of all journal articles available in St. Francis library for the past ten years. LIE DETECTOR RESEARCH AIDED BY COMPUTER Prof. William Yankee, academic dean of Delta College (University Center, Mich.) and a nationally known polygraph expert, is us ing an IBM computer to more accurately analyze factors he feels are critical in determining deception by a polygraph test subject. At present, polygraph test results are only as reliable as the operator of the machine. "We hope to develop formulas to cut errors in human evaluation," Prof. Yankee said. His project is based on the bel ief that changes in heart rate, pulse amplitude, diastolic and systolic blood pressure, breathing patterns and the skin's resistance to electricity can be evaluated and measured on the computer. The research involves commission of a mock theft by student volunteers, who then submi t to the polygraph 48 with instructions to answer in the negative to all questions. Results are correlated by an IBM System/360 Model 40 computer, enabling researchers to better determine at what point in the tests deception occurred. The picture shows Prof. age, weight and sex. The computer reports the findings on a printer near the spirometer and is ready for the next patient. Since the breathing test can be administered anywhere long distance communications lines exist to link the spirometer with the IBM 1800 data acquisition and control system, the test is able to reach large numbers of people. When lung disorders are indicated by the computer, x-rays and other methods of detailed examination are used to pinpoint the extent and exact nature of the problem. CALIFORNIA WILL SOON COMPUTERIZE ADOPTIONS Yankee, left, and Ben Paulson, systems analyst, examining a student test record. Items listed on the sign are among those used in the mock thefts. COMPUTER-BASED BREATHING TEST AIDS EARLY DETECTION OF LUNG DISEASE Researchers at the Uriivers i ty of Nebraska Medical Center have developed a computer-based breathing test to aid in early detection of crippling lung disease. The proj ect was partially funded by the Nebraska Tuberculosis and Respiratory Disease Association. Government reports rank lung diseases sixth among fatal diseases and our fastest ris ing public health problem. Only heart disease cripples more working men between the ages of 40 and 45. At best, lung damage can only be arres ted, not reversed; therefore, early detection is v i tally important. Using an IBM system and portable test equipment, doctors are able to screen large numbers of people quickly and inexpensively. The test consists of two parts: a brief questionnaire indicating a patient's his tory of pas t lung diseases; and, a breathing test performed by a portable spirometer,which measures the volume and rate of air leaving the lungs. The breathing test which takes only three minutes is as follows: the patient exhales forcefully and rapidly into a tube attached to the spirometer and the computer compares the flow, volume and duration of the exhalation against standards for persons of the same The State of California soon will begin using electronic data processing to match hard-to-adopt children wi th potential adoptive parents. Hard-to-adopt children, traditionally one of the major headaches of the adoption agencies, generally include children with handicaps, those from minori ty groups and/or older children. Most adoptive parents want a newborn baby with physical characteristics similar to their own. Michio Suzuki, social services division chief of the State Social Welfare Department, and Helen Clauson, chief of the Adoption and Foster Care Bureau said the new system should substantially increase the placement of these hardto-adopt children. At present the information exchange relative to placing the children is handled by various adoption agencies on a regional basis. Representatives meet periodically in an attempt to obtain possible matches a laborious and time-consuming process. Under the new sy stem, the name s of all children who have been reI inquished to adoption agencies in the state for more than 60 days will be fed into a computer along wi th the names of all prospective parents who do not have a child under cons ideration for adoption.

PDP-8 AUTOMATES STAR THEATER AT STRASENBURGH PLANETARIUM Strasenburgh Planetarium (Rochester, N.Y.) plans to become the world's first totally automated "Star Theater." The project, undertaken by the Roches ter Museum and Science Center and Yondata Corp., aims to provide a "total experience" of meaning and enj oyment to the public. Hopefully, by July 1970, phase two of the proj ect will permi t Digi tal Equipment Corporation's COMPUTERS AND AUTOMATION for March, 1970 PDP-8 computer to control all of the movements of the giant-sized Zeiss Model 6 Planetarium Projector. Presently, the PDP-8 controls special light and sound effects which include: 300 projectors of different size and type located around the periphery of the planetarium's 65-foot dome; numerous light banks; 3 tape decks in the sound system; and, a double series of 12 custom-built panoramic projectors with cross-fade capability that can be used to simulate a limitless variety of horizon scenes. Wi th the completion of phase two, the planetarium will have a total system for automated programs to standardize, refine and repeat all shows perfectly. The system eliminates the possibili ty of human error that is always present in manually operated live shows. In addition, dificult routines can be repeated perfectly every time. For example, a moon rocket sequence would require several dozen different and distinct movements of the controls within a few seconds - impossible for a man to do. The routine, therefore, has been compromised in the past. The PDP-8 will be able easily to complete up to 500 such moves wi thin the same period of time. 4000 FREIGHT CARS PER DAY AUTOMATICALLY SWITCHED BY COMPUTER IN RAILROAD YARD A computer in Southern Pacific's Houston (Texas) railroad yard automatically directs the switching of some 4000 freight cars a day. An IBM 1800 data acquisition and control system allows switching of each car into any of 64 tracks in the Englewood Yard, where trains are assembled. The cars are headed for delivery to hundreds of different destinations across the country. the "hump". The IBM system consul ts stored information and, as the cars start down, takes control of routing, automatically triggering the switches that send the rolling car to the proper track. On the average, this procedure is repeated 4000 times each day as some 29 freight trains are assembled.
