This article is the documentation of a sub-research question of a larger empirical study that employed quantitative methods to identify variables that are impacting on the delivery of music in the learning area Arts and Culture in South Africa extrapolated from questionnaires. Analysis of the data revealed that educators lack specialisation in…

This study investigated elementary school students' environmental knowledge and attitudes, the effects of sociodemographic variables on environmental knowledge and attitudes, and how self-reported environmentally friendly behaviour is related to environmental knowledge, behavioural intentions, environmental affects, and the students' locus of…

This article proposes alternative expressions for the two most prevailing definitions of suppression without resorting to the standardized regression modeling. The formulation provides a simple basis for the examination of their relationship. For the two-predictor regression, the author demonstrates that the previous results in the literature are…

Suppressor effects are considered one of the most elusive dynamics in the interpretation of statistical data. A suppressor variable has been defined as a predictor that has a zero correlation with the dependent variable while still, paradoxically, contributing to the predictive validity of the test battery (P. Horst, 1941). This paper explores the…

Focuses on the procedures available for substituting a special predictive coding method for some of the more complex general regression procedures. (Author)

Conventional canonical methods distinguish between the two variable sets being analyzed, but the methods do not attempt to optimize the variance from a given variable set that will be contained in the final solution. In this respect canonical methods are said the be "symmetric." This paper proposes two non-symmetric, canonical-like…

The problem which this study addresses is the effects of cognitive style and variations in the free sort procedures on the sorting outcome of sorting time and number and quality of manifest partitions. This experiment was designed to look at the effects of the cognitive styles of field dependence, category width and equivalence range,…

The Automatic Interaction Detector (AID) is discussed as to its usefulness in multiple regression analysis. The algorithm of AID-4 is a reversal of the model building process; it starts with the ultimate restricted model, namely, the whole group as a unit. By a unique splitting process maximizing the between sum of squares for the categories of…

Many proposed moderators, "explanatory variables," in personnel psychology are probably illusory, having been created solely by belief in the law of small numbers. Race is one such illusory moderator. Also described is a model for validity generalization that questions the traditional doctrine of situational specificity of test…

Since actual selection can be different from the selection as it is intended, a method is described for clarifying "restriction of range" problems in developing selection/prediction equations. The application of the method is illustrated in a case study. (Author/JKS)

Describes a study that examined the characteristics of uncited papers in the biomedical literature. The variables examined included number of authors; number of words in title; number of references; journal age, price, and circulation; research support from the National Institute of Health; and biomedical research level. (18 references) (CLB)

The purpose of the study was to determine if the constructs of teaching presence and the sense of community function as predictors of perceived student learning in an online course. Each participating online student completed an online survey comprised of an informed consent, an item regarding their perception of learning (Richmond et al., 1987),…

The purpose of the study was to investigate the job satisfaction of men and women administrators in higher education in four-year public institutions in Alabama. In addition, the study examined whether there was a relationship between gender and overall job satisfaction, work climate, and job structure. In conducting the study, the researcher…

Although social justice advocacy has increasingly been acknowledged as important in the field of psychology (e.g., Goodman et al., 2004; Toporek et al., 2006a, Vera & Speight, 2003), there is a dearth of empirical research examining social justice advocacy across graduate psychology students. This mixed-methods study examined demographic and…
