Social identity and intergroup evaluative bias: Realistic categories and domain specific self-esteem in a conflict setting

Social identity theory predicts a link between self-esteem and intergroup discrimination. Previous research has failed to find consistent support for this prediction. Much of this research has, however, been beset by a number of methodological shortcomings. These shortcomings may have hindered attempts to discern a consistent relationship between self-esteem and intergroup discrimination. The current investigation sought to overcome these difficulties by utilizing, realistic groups, multidimensional measures of self-esteem and testing self-esteem before and after the manifestation of intergroup evaluative bias. The results demonstrate that when the members of realistic groups engage in evaluative intergroup bias, the esteem in which they hold specific self-images is enhanced. Of the 13 facets of self-esteem delineated by the instrument used in the present study significant increases were found in six particular domains: honesty, academic ability, verbal ability, physical appearance, religion and parental relations. Global self-esteem was unaffected by the display of bias. These findings emphasize the importance of using realistic groups and domain specific self-esteem when attempting to assess the role of self-esteem in intergroup discrimination.     

Expectancy,value, and attitudinal semantics

A novel single-attribute test between competing expectancy-value models of attitude was devised using subjects' ratings of clusters of statements located at a range of points within a three-dimensional semantic space with expectancy, value and attitude as the co-ordinates. The data provided strongest support for a model using bipolar scoring for evaluation and unipolar scoring for expectancy.     

Leadership Style,Anonymity, and Creativity in Group Decision Support Systems: The Mediating Role of Optimal Flow

ABSTRACT Prior research indicates that flow, a psychological state characterized by concentration, enjoyment, and intrinsic motivation, may be linked to creativity of individuals participating in computer-mediated meetings. A laboratory experiment was conducted to evaluate the effects of leadership style (transactional contingent reward and transformational) and anonymity level (identified and anonymous) on flow and creativity of 159 undergraduate students working in groups performing a creativity task using a Group Decision Support System (GDSS). Results demonstrated that flow mediated effects of leadership on creativity in a GDSS context, and its role may be moderated by anonymity. Results also indicated that both flow and anonymity were required for enhancing creativity in a GDSS context. Implications for practice and research are discussed.     

HR OUTSOURCING AND ITS IMPACT: THE ROLE OF TRANSACTION COSTS

Although HR activities have traditionally been performed in-house, organizations are increasingly relying on outside contractors to perform these activities. Using a Transaction Cost Economics perspective, this study examined whether organizational-level factors moderated the relationship between the degree of reliance on HR outsourcing and the perceived benefits produced by outsourcing. Moderated regression was performed using data provided by over 300 HR executives on outsourcing levels, organizational characteristics, and the perceived impact of outsourcing. Support was found for a number of the transaction cost hypotheses regarding the impact of organizational characteristics. Specifically, the relationship between the degree of outsourcing and the perceived benefits generated was moderated by reliance on idiosyncratic HR practices, uncertainty, firm size, and cost pressures. No support was found for hypotheses regarding the moderating effect associated with pay level, overall outsourcing emphasis, or strategic involvement by HR.     

ON USING RESIDUAL DIFFERENCE SCORES IN THE MEASUREMENT OF CONGRUENCE: THE CASE OF MET EXPECTATIONS RESEARCH

Despite meta-analytic support for the met expectations hypothesis, Irving and Meyer (1994, 1995) suggested that methodological problems such as the use of difference scores and retrospective measures of met expectations have resulted in an overstatement of this support. In a recent article, Hom, Griffeth, Palich, and Bracker (1998) simultaneously tested several potential psychological mediating mechanisms of realistic job preview (RJP) effects. These authors suggested that met expectations is a critical mediating mechanism, having direct effects on job satisfaction and indirect effects on organizational commitment, withdrawal cognitions, and actual turnover through job satisfaction and other mediating mechanisms such as coping efficacy and perceived employer honesty. However, they used "residual gain scores" to measure met expectations. In this article, we demonstrate that the use of residual scores for the purposes of operationalizing met expectations creates the same problemsas does the use of difference scores a technique that has been widely criticized in the literature.
