An alternate type of simulation was developed that might make the study of accounting more relevant and the retention of the material greater. Half of the students completed a conventional business practice set; half created a simulated business, designed an accounting system, and constructed transactions. (JOW)

A split-sample replication stopping rule for hierarchical cluster analysis is compared with the internal criterion previously found superior by Milligan and Cooper (1985) in their comparison of 30 different procedures. Situations under which the methods are equivalent or not equally useful are discussed. (SLD)

Computer simulations are described in which pairs of simulated individuals in groups play a prisoner's dilemma game, with the choice to cooperate determined by one of three simple heuristics. Results reveal that the prevalence of cooperation depends on the heuristic used, value of the payoff, and the social comparison process. (SLD)

The parallel distributed processing model of visual word recognition in reading developed by Seidenberg and McClelland (1989) is extended through simulation. A response by Seidenberg and McClelland recognizes merits of the expanded model and outlines requirements for supplanting their original model. (SLD)

Type I error rates for the Mantel-Haenszel (MH) statistic were within nominal limits when the MH procedure was compared with the simultaneous item bias (SIB) method for detecting differential item functioning. Results with data simulated for 1,296 conditions found Type I error rates slightly higher than expected for SIB. (SLD)

Discussion of the use of consensus-building techniques to resolve public policy disputes focuses on the use of a simulation of the conflict that needs to be resolved. An example is given of the National Energy Policy Simulation that was designed by the Massachusetts Institute of Technology (MIT)-Harvard Public Disputes Program. (38 references)…

A recursive equation is proposed for computing higher order derivatives of elementary symmetric functions in the Rasch model. A simulation study indicates a small loss in accuracy for the proposed formula compared to Gustafsson's sum algorithm (1980) for computing higher order derivatives when tests contain 60 items or less. (SLD)

A discipline in which scientists seek to simulate and synthesize lifelike behaviors within computers, chemical mixtures, and other media is discussed. A computer program with self-replicating digital "organisms" that evolve as they compete for computer time and memory is described. (KR)

A simple procedure for measuring changes in the acoustic impedance of the ear is described. The technique has several applications, including simulation using a standard coupler of changes in real ear impedance produced by the acoustic reflex, and calibration of response time of an otoadmittance meter. (Author/DB)

Discussion of the interpolation methodology expounded by Goosen and Kusel to model business functions for simulation design criticizes the approach's simplicity because interactive effects between variables in the functional relationships are not considered. (six references) (EA)

Advantages of simulation are link between classroom and real experience, experiment with risk, intensive focus, and reflection on experience. It can involve rigorous and time-consuming preparation, unpredictable outcomes, and trainee resistance. Facilitators need good coaching skills and personal sensitivity. (SK)

Meaningful role plays have three phases: warm-up, which creates an environment that fosters interaction and overcomes resistance; action, during which protagonists and auxiliaries are chosen and the action is periodically frozen for reflection and feedback; and closure, to reinforce learning and plan its integration into job performance. (SK)

Simulated population data were used to compare relative performances of the modification index and C. Chou and P. M. Bentler's Lagrange multiplier test (a multivariate generalization of a modification index) for four levels of model misspecification. Both indices failed to recover the true model except at the lowest level of misspecification. (SLD)

Coordination is a key issue in the design of organizational structures and processes. In this article, the authors propose a body of concepts that support the modeling and computer simulation of organizational processes and organizational coordination. Three aspect models are described that highlight different coordination aspects, and future…

Investigated the effects of types and prevalence of response patterns that might be provided by nonattending respondents on Cronbach's alpha (L. Cronbach, 1970) using three simulated data sets. Effects were greater as a function of increased prevalence in the respondent group, but as few as 5% of some types of nonattending patterns had inflating…
