Knowledge that Transforms

The present study extends knowledge of the performance consequences of workgroup diversity climate. Building upon Kopelman, Brief, and Guzzo's () climate model of productivity, we introduce workgroup discrimination as a behavioral mediator that explains the positive effects of diversity climate on workgroup performance. In addition, we investigate group size as a moderator upon which this mediated relationship depends. We test these moderated‐mediated propositions using a split‐sample design and data from 248 military workgroups comprising 8,707 respondents. Findings from structural equation modeling reveal that diversity climate is consistently positively related to workgroup performance and that this relationship is mediated by discrimination. Results yield a pattern of moderated mediation, in that the indirect relationship between workgroup diversity climate (through perceptions of workgroup discrimination) and group performance was more pronounced in larger than in smaller workgroups. These results illustrate that discrimination and group size represent key factors in determining how a diversity climate is associated with group performance and, thus, have significant implications for research and practice. © 2014 Wiley Periodicals, Inc.

The research undertaken here examines how an organizational work‐family culture affects the attitudes of working mothers. This research extends the existing findings by examining two separate mediation processes: work‐family conflict and career expectations. The cases of 1,308 working mothers were analyzed using structural equation modeling. Results show that career expectations mediated the effect of an organizational work‐family culture on affective commitment while work‐family conflict did not. As an additional analysis, working mothers’ perceptions and attitudes were compared with those of 288 peers. Results disclose that working mothers were no less committed to their organization, and were even more committed than their peers early in their careers. Working mothers’ career expectations, however, were consistently lower than their peers’ expectations. Implications of these results are included. © 2014 Wiley Periodicals, Inc.
