This paper describes in detail the instruction of an introductory statistics course using the computer not only for tutorial CAI support, but also for the generation of statistical exercises and answers and for its capabilities as a tool to help students complete data analyses. (Author)

A model which relates the access control and indexing functions. The model is based on concept protection which allows a practically unbounded number of levels (subsets) of protection without requiring a fixed hierarchy among the levels. This protection is offered independently for each of the user operations allowed. (Author)

Useful programming tricks are suggested to allow the reduction of many equations and non-polynomial-like expressions and the subsequent application of the mathematical algorithms. (Author)

A number of basic concepts relating to debugging are identified and a gross theory of debugging is described. (Author)

The relationship between meaning and vocabulary in four professions--anthropology, linguistics, psychology, and computer science--is examined. Current relational theories within each profession are compared with respect to goals, methodologies, and proposed relations. Certain core relations appear in each discipline, and these are tabulated and…

This document assesses the status of charge-transfer device technology as displayed by foreign research and manufacturing facilities for a period up to September 1975. Capabilities and accomplishments of charge-transfer device research facilities in Japan, Canada, Great Britain, The Netherlands, The Federal Republic of Germany, and the United…

A smooth program is defined to be one which is "go to"-free in the sense that it can be represented by a flowchart consisting only of concatenation, alternation, and interation elements. Three methods of eliminating the "go to" statement from a program have been proposed: (1) the introduction of additional Boolean variables or the equivalent…

The computer programing language APL is used to describe a "learning" game, and the functions developed are generalized to extend to a class of rules. (Author/WH)

A macro system is implemented within the Coursewriter programing language. It is designed as a time-saving system to eliminate the repetitive coding of general routines. These routines, consisting of a series of instructions originally developed to handle one particular problem (or problem section), can, with little or no modification, be…

This report is based on a roundtable discussion held on January 21 and 22, 1970. The meeting was called by the American Federation of Information Processing Societies (AFIPS) because of the concern felt by many in the computing profession for a better understanding of what is meant by "professionalism," and the associated question of "professional…

Investigated was the management of computer centers with emphasis on managing the programming effort. Problems and objectives of programming management were examined and techniques used in various business and governmental organizations are presented in the report. The aspects of the problem discussed in this report emphasize programming…

The Chemistry Department at the University of California, San Diego, has 35 members, 20 of whom are experimentalists with either computers or plans to acquire one. Within the department there are turn-key systems connected to mini-computers or the department computer, an IBM 1800. There is little control over computers in the department and little…

An overview is provided of the Experimental Time-Sharing System (ETSS). Few manufacturers of small-scale and medium-scale computers offer operating systems capable of supporting both terminal-oriented time-sharing and multiprogramed batch processing. ETSS was developed to demonstrate that a powerful, general purpose operating system of this type…
