Theories employed to explain regularities in social behavior often contain explicit or implicit reference to the presence of nonlinear and/or nonadditive (i.e., multiplicative) relationships among germane variables. While such nonadditive features are theoretically important, the inclusion of quadratic or multiplicative terms in structural…

Hypothesis generation and testing is outlined as an additional domain for program evaluators. Program evaluation involves a thorough analysis of the processes that contribute to change (or a lack of change) among program recipients. This process of change is analyzed in two ways: (1) treating programs as naturally occurring field studies; and (2)…

An extension of the methods of path analysis to include studies of categorical data was described and exemplified in a causal study of college dropouts. The usual models and methods of causal (path) analysis were designed for the study of quantitative variables and are not appropriate when the variables under investigation are categorical.…

The mathematical derivation of the statistics used for inference in some linear models assumes that the values of the independent variables are measured without error. This assumption is often disregarded when these models are utilized in research. This study is an investigation of the consequences of the violation of this assumption for one…

This article points out the flaws inherent in the hypothetico-deductive formulation of inquiry. (CD)

Critical issues and methodological problems concerning migration and mental health are examined. A model for determining predictor variables of depression in immigrant Mexican women is tested. Demographic, economic, and interpersonal factors are isolated as a subset of depression predictors within the model. (VM)

Author discusses science discovery lessons, presents a model of one, and offers suggestions for structuring other specific lessons. (Editor/MB)

Social researchers under the influence of social stereotypes sometimes make generalizations which are partly true and partly false, and tend to use deceptive research models which in turn increase the number and influence of stereotypes. (JM)

A path analytic model is hypothesized and tested to explain the effect of a series of intellective and nonintellective student attributes on high school achievement and college achievement. Patterns of predictability for male and female students are compared. (Author/GK)

Describes the basic philosophy, nomenclature, and techniques used in mathematical modelling to enable biologists, engineers, land managers, and others to understand the concepts and usefulness of models. Contrasts conceptual and empirical approaches, using ecosystem models as an example of the former. (DC)

Reviews the eye-movement paradigm and refers to recent experiments applying the paradigm to issues of spoken word recognition (e.g., lexical competitor effects), syntactic processing, reference resolution, focus, as well as issues in cross-modality integration that are central to evaluating the modularity hypothesis. (Seven references) (Author/CK)

Synthesized empirical findings on job satisfaction from the first 26 volumes of "Educational Administration Quarterly." Discovered 330 job satisfaction research hypotheses and 613 relational effect sizes. Performed meta-analyses for six hypotheses, finding the largest mean effect sizes for relationships between overall job satisfaction…

Proposes a research model to test the dependence of a field list of internationally visible journals on the initial set. Outlines applications of the experiment and hypothesizes on the validity of the Institute of Scientific Information's (ISI) impact factors. Suggests that in some cases lists of journals selected by linguistic or geographic…

Based on Luria-Das information processing theory, hypothesized that 26 educable mentally retarded children would score significantly less well on relatively pure measures of planning ability than would 13 younger average ability students after students were matched on cognitive processing ability. Hypothesis was not supported by study. (Author/NB)
