Small sample behaviour of some nonparametric multi-sample location tests in the presence of dispersion differences

This paper describes the small and moderate sample behaviour of three studentized non-parametric statistics by Sen and a modified Wilcoxon statistic by Potthoff for testing the equality of location parameters in the presence of dispersion differences. Based on the agreement between the asymptotic and small sample distributions of the statistics as well as a comparison of their power under heteroscedasticity, the studentized Wilcoxon and the studentized Brown and Mood tests arc preferred in the two-sample and c-sample situations, respectively.     

Why I am a Psychology Major: An Empirical Analysis of Student Motivations

The underlying “architecture of the decision to pursue a degree in psychology was quantified using the Method of Sorting technique to identifying the critical issues necessary to make this choice. Multidimentsional scaling procedures were employed to construct a three-dimensional map representing the relationships between reasons for selecting psychology as a major. Freshman and senior psychology majors (N = 165) from a regional university and a large research-based institution rated the relative importance of items in their decision-making process. Hierarchical clustering procedures revealed seven different groups of students. Although significant differences associated with class standing were not found, institutional affiliation did influence cluster composition. Reflecting local emphases, students at the regional institution had a greater interest in Counseling Psychology, whereas those at the research-based school focused on Clinical Psychology. This semantic map and the associated item clusters arising from psychology student data provides an empirical basis for, amongst other things, course selection, faculty-initiated program design or revision, strategic niche marketing, and student retention.     

HRM practices and organizational commitment profiles

In this study, we examined how employee perceptions of development-oriented, stability-oriented, and reward-oriented human resource management (HRM) practices affected the likelihood of affective and continuance commitment profile membership. Our focus on profiles of combined commitment components is a departure from a literature dominated by studies of the separate forms of employee commitment. Drawing from self-determination theory (Deci and Ryan 2000) we described the nature of the psychological states believed to underlie the specific profiles under investigation, then tested a series of theoretical predictions concerning the link between HRM practices and the likelihood of profile membership. Predictor and criterion data for this study were collected from 317 respondents working in a variety of Canadian-based organizations. Our findings suggest ways that organizations can use HRM practices strategically to help shape the nature of overall employee commitment.     

Corporate giving in the USA: a model for meeting Russia's expanding social needs?

In the USA, corporations make substantial contributions to public‐serving organisations with no expectation of financial gain. This paper explores the factors that have encouraged corporate giving in the USA and compares them to circumstances in the emerging capitalist economy of Russia. The outlook for the emergence of a corporate giving model in Russia similar to that of the USA is poor, but improving. To make it work, organisational recipients of corporate generosity need to trust their benefactors, and corporations need to believe that their contributions of surplus profits make good business sense.

Strategic individual assessment: Issues in providing reliable descriptions

Individual assessment involves one psychologist making an assessment of an individual for personnel-related purposes. Individual assessment practice is reviewed, and research on reliability is presented. A study examining the comparability of conclusions reached by consumers is presented. Eighty-six students and thirty-eight managers read nine narrative assessment reports (three of each of three job candidates) and attempted to determine which reports described the same candidate. None of the subjects could correctly group the nine reports; a sizeable proportion did no better than chance in grouping the reports. Implications for assessors and consumers of individual assessments are discussed.     

The Kornai effect with partial bailouts and taxes

The model examines Kornai's observation that in the presence of bailouts, firms' demand for inputs will be greater than would otherwise be the case. This conjecture is examined in a model in which both revenue and cost uncertainty are present and in which firms making losses are partially subsidized and firms making positive profits are partially taxed. The Kornai effect is more prevalent the greater the subsidy rate, the smaller the tax rate and the greater the variance of the random variables through which uncertainty manifests itself. In the case of strongly positively correlated cost and revenue uncertainty, the absolute incidence of the Kornai effect is small.
