One of the major problems that a tree-approach to data analysis often encounters is the instability of tree-structures. The instability issue must be dealt with before data can be interpreted by this method. Examining instability at a node of a tree provides insight into the instability of the whole tree, because the same theory of instability…

Actors have been trained to portray patients with a variety of physical and emotional disorders for the purpose of teaching and evaluating clinical skills. Suggests that actors considered for simulations of patients be screened on the basis of sufficient acting experience and motivation for the role. (Author/PG)

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.

The document describes the 1972 version of the International Relations Exercise (IRE) used at the Industrial College of the Armed Forces (ICAF). During the IRE, supplementary information, described in section 2.0, is also provided to participants. This supplementary information is not released for publication. The IRE is an outgrowth of continued…

The use of quantitative predictive models has become increasingly important to urban and regional planners within the past decade. The increasing sophistication of urban and regional information systems and of hardware devices has helped to make possible the acceptance and application of models by planners. The sources contained in this…

This review analyzes current research trends in the application of planning models to broad educational systems. Planning models reviewed include systems approach models, simulation models, operational gaming, linear programing, Markov chain analysis, dynamic programing, and queuing techniques. A 77-item bibliography of recent literature is…

This paper reports an effort to develop and field test a new social learning model for school psychologists. The conclusions of the research thus far completed would indicate strongly that it is entirely possible to recruit and retrain existing school psychologists making effective changes in both their cognitive and behavioral approach to school…

The objectives and dimensions of this analysis system are described in SO 000 835. However, this document contains the actual instrument which was designed to provide a method of analyzing autotelic educational material such as games and simulations. It was created for curriculum supervisors, chairmen, and teachers who make curriculum decisions,…

This study attempts to determine whether the human intellectual process of cataloging bibliographic materials, using the Anglo-American (AA-1967) and American Library Association (ALA-1949) cataloging codes, can be simulated by automatic techniques. The specific cataloging process is that which concerns selection of entry. Automatic techniques…

The aim of this study was to develop methods, based upon computer simulation, of designing information systems and illustrate the use of these methods by application to an information service. The method developed is based upon Monte Carlo and discrete event simulation techniques and is described in an earlier report - Sira report R412 Organizing…

This report describes the initial evaluation of a text compression algorithm against computer assisted instruction (CAI) material. A review of some concepts related to statistical text compression is followed by a detailed description of a practical text compression algorithm. A simulation of the algorithm was programed and used to obtain…

Describes the disadvantages of using "canned" simulations as a part of an undergraduate economics course. Identifies four advantages of having students develop their own computer simulation models. Outlines the model-building process and displays a sample program. (JDH)
