Mounting pressure in the policy arena to improve teacher productivity either by improving signals that predict teacher performance or through creating incentive contracts based on performance--has spurred two related questions: Are there important determinants of teacher productivity that are not captured by teacher credentials but that can be…

The nature and use of LISREL (LInear Structural RELationships) analysis are considered, including an examination of college students' commitment to a university. LISREL is a fairly new causal analysis technique that has broad application in the social sciences and that employs structural equation estimation. The application examined in this paper…

This paper examines the multivariate multiple regression model and explores its applicability to communication research. The first section discusses partitioning of a data matrix, as a heuristic device for distinguishing among alternative regression models. Section two examines various aspects of univariate multiple regression, including the form…

This document addresses the problems facing researchers who are involved in evaluating worker potential across the life-span, including that most evidence focusing on differential job ability levels within age classifications has come from empirical investigations concerning functional age. A critique of the functional age approach is presented…

A LISREL analysis demonstrates the value of regressing reputational ratings on three latent variables: size, faculty research productivity, and the quality of program graduates. The model was tested using National Research Council data for each of six disciplines: English, French, philosophy, geography, political science, and sociology.…

A discriminant analysis of objective and subjective measures from the records of students who graduated from the University of Medicine and Dentistry of New Jersey-New Jersey Medical School over a six-year period was used to generate a model for the prediction of medical specialty choice. (Author/MLW)

A new model is developed that takes into consideration the relationship of occupational mobility to relevant factors such as education, discrimination, market fluctuation, and aspirations. (IS)

Converse's black-and-white model of attitude stability, in which there are some stable opinion holders and a group of nonopinion respondents whose positions vary over time, is supported. Relationships of education and political involvement to opinion holding suggest that respondents hold stable opinions on issues that are most important to them.…

Since the Hotelling-Clawson approach to estimating the demand for recreation resources assumes only one destination with no substitutes, alternative estimation techniques are presented and tested. Implications of the use of these techniques are discussed. (JN)

The present study examined a longitudinal model of state and trait negative affect as predictors of job-search success. Job-search self-efficacy and job-search intensity were also examined as mediators of the negative affect--job-search success relation. Overall the model offered mixed support for Kasl's (1982) Reverse Causation Hypothesis.…

In their meta-analysis of clinical versus statistical prediction models, Aegisdottir et al. (this issue) extended previous findings of statistical-method superiority across such variables as clinicians' experience and familiarity with data. In this reaction, the authors are particularly interested in violence prediction, which yields the greatest…

The correspondence between the Hare Psychopathy Checklist: Screening Version (PCL:SV; S. D. Hart, D. N. Cox, & R. D. Hare, 1995) and the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991, 2003) was examined in forensic (N = 175) and correctional (N = 188) samples. Intermeasure correlations for Total scores (0.95 forensic, 0.94…

The application of scientific tools to analyse the use of Internet-based e-learning tools in academic settings is in general an ignored area. E-learning tools are actually an emergent topic as a result of the new ideas introduced by the European Higher Education Area. Lifelong learning, or the promotion of student initiative, is the new paradigm…

A major model to forecast requirements for health professionals, which is currently used by the Division of Health Professions Analysis of the U.S. Public Health Service, is described. Specifically, technical documentation is provided for the projections to 1990 that are presented in "A Report to the President and Congress on the Status of…

An accurate forecast of the student demand by level on the academic departments of an institution is vital for budget and financial planning decisions, for faculty workload scheduling, and for physical facility planning. Many methods have been used to forecast this demand, ranging from "seat of your pants" guessing to highly complex…
