The issue of workforce diversity has been at the forefront of organizational concerns for many years. Not surprisingly, this topic has generated reams of research aimed at shedding light not only on the challenges involved, but also on ways these challenges have been and can be addressed. This paper reports on a comprehensive survey of the most recent studies in an effort to uncover what has been learned and what remains to be examined. While the paper is aimed primarily at researchers, it also offers a number of insights of relevance to managers and others who are responsible for designing and administering diversity-related initiatives in today's organizations.
The extent to which leadership influences employee health and the processes that underlie its effects are not well understood at present. With the aim of filling this gap, we review four distinct forms of leader behavior (task-oriented, relationship-oriented, change-oriented, and passive/destructive) and clarify the different ways in which these can be expected to have a bearing on employee health. Next, we present a model that integrates and extends these insights. This model describes five pathways through which leader behavior can influence the health of organizational members and summarizes what we know about the most important determinants, processes (mediators) and moderators of these relationships. These involve leaders engaging in personfocused action, system-or team-focused action, action to moderate the impact of contextual factors, climate control and identity management, and modelling. Finally, we identify important gaps and opportunities in the literature that need to be addressed in future research. A key conclusion is that while much has been done to explore some key pathways between leadership and health, others remain underexplored. We also outline how future research might address these in the context of a more expansive theoretical, empirical and practical approach to this emerging field of research.
Faultlines-hypothetical dividing lines splitting a group into homogeneous subgroups based on the distribution of demographic attributes-are frequently assumed to be detrimental to group outcomes because they operationalize social categorizations. However, a literature review indicates that this is not always the case. We argue that diversity faultlines and social categorizations are not necessarily the same and that the effect of diversity faultlines is moderated by perceived social categorizations. To test this proposition, we assigned 172 participants to groups of four. Participant gender, bogus personality feedback, seating position, and colored cards were employed to create two diversity faultline conditions (weak and strong faultline). Groups worked on the Survive in the Desert task, and their interactions were coded with the discussion coding system (DCS). Social categorizations were elicited using a newly developed measure that requires participants to specify subjectively perceived salient categories. Participants stated many social
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
