Describes the Simple Averaging Model (SAM) which was developed to demonstrate impression-formation computer modeling with less complex and less expensive procedures than are required by most established programs. (RC)

A copy of the program is available from the second author at the Department of Psychology, LSUNO-Lakefront, New Orleans, Louisiana 70122. (Authors/CB)

Describes British Library's work on Systems Dynamics, a set of techniques for building simulation models based on analysis of information feedback loops. Highlights include macro-simulation modelling activities of social science disciplines, systems analyses and models of information retrieval processes and library services, policy models, and…

A systematic procedure for developing more accurate estimates of college admission parameters was established. This system quantitatively encodes subjective logic used by decision-makers to combine historical data, statistically derived sample estimates from the current year, and subjective estimates of the decision-maker. (Author)

Computer simulation, a valuable tool for architects and urban designers, can produce unexpected pitfalls, costs, and results. (Author)

Described is a computer simulation designed to introduce students to some of the intricate relationships between the many factors involved in international economics. (MP)

Defines a hash coding model for non-unique search keys and derives the expected number of accesses needed to retrieve all desired records from a computer storage device. (Author)

An analysis to ascertain which electronic data processing (EDP) systems are most flexible in processing wide ranges of volumes efficiently. A simulation model of the job environment of three common EDP systems provides information on the shape of their cost functions in the neighborhood of optimality. (Author/LS)

TO BETTER UNDERSTAND THE COGNITIVE PROCESSES INVOLVED IN THE ATTAINMENT OF CONCEPTS BY HUMANS, A MODEL WAS DEVELOPED BY USE OF COMPUTER TECHNIQUES. THE MODEL WAS BASED UPON THEORETICAL GROUNDS, "THINK ALOUD" PROTOCOLS, AND SPECULATIONS ABOUT THE NATURE OF CONCEPT ATTAINMENT. IT WAS DEVELOPED WITH THREE MAJOR ASPECTS--(1) CONTEXTING FUNCTIONS…

A MODEL OF THE MATHEMATICS DEPARTMENT AT THE GARBER HIGH SCHOOL AS ESSEXVILLE, MICHIGAN, AS A SYSTEM FOR PROCESSING STUDENTS WAS DESCRIBED IN THE LAST OF A SERIES OF THREE REPORTS. THE RESULTS OBTAINED THROUGH SIMULATING THE SYSTEM ON A COMPUTER WERE ALSO REPORTED. A FEATURE OF THE PLAN WAS NOTED TO BE ITS FLEXIBILITY IN PROVIDING A UNIQUE PROGRAM…
