Leading virtual teams: hierarchical leadership, structural supports, and shared team leadership.

Using a field sample of 101 virtual teams, this research empirically evaluates the impact of traditional hierarchical leadership, structural supports, and shared team leadership on team performance. Building on Bell and Kozlowskis (2002) work, we expected structural supports and shared team leadership to be more, and hierarchical leadership to be less, strongly related to team performance when teams were more virtual in nature. As predicted, results from moderation analyses indicated that the extent to which teams were more virtual attenuated relations between hierarchical leadership and team performance but strengthened relations for structural supports and team performance. However, shared team leadership was significantly related to team performance regardless of the degree of virtuality. Results are discussed in terms of needed research extensions for understanding leadership processes in virtual teams and practical implications for leading virtual teams.

Do Ethical, Authentic, and Servant Leadership Explain Variance Above and Beyond Transformational Leadership? A Meta-Analysis

This study compares three emerging forms of positive leadership that emphasize ethical and moral behavior (i.e., authentic leadership, ethical leadership, and servant leadership) with transformational leadership in their associations with a wide range of organizationally relevant measures. While scholars have noted conceptual overlap between transformational leadership and these newer leadership forms, there has been inadequate investigation of the empirical relationships with transformational leadership and the ability (or lack thereof) of these leadership forms to explain incremental variance beyond transformational leadership. In response, we conducted a series of meta-analyses to provide a comprehensive assessment of these emerging leadership forms’ relationships with variables evaluated in the extant literature. Second, we tested the relative performance of each of these leadership forms in explaining incremental variance, beyond transformational leadership, in nine outcomes. We also provide relative weights analyses to further evaluate the relative contributions of the emerging leadership forms versus transformational leadership. The high correlations between both authentic leadership and ethical leadership with transformational leadership coupled with their low amounts of incremental variance suggest that their utility is low unless they are being used to explore very specific outcomes. Servant leadership, however, showed more promise as a stand-alone leadership approach that is capable of helping leadership researchers and practitioners better explain a wide range of outcomes. Guidance regarding future research and the utility of these three ethical/moral values–based leadership forms is provided.

Shared leadership, diversity, and information sharing in teams

Purpose – Shared leadership is increasingly important in todays organizations. The purpose of this paper is to examine the association between shared leadership and team performance, the moderating role of demographic diversity and the mediating role of information sharing on this relationship. Design/methodology/approach – The research used a field study design, quantitative data of employees from two different organizations. Data were analyzed with structural equation modeling analyses. Findings – Shared leadership was positively associated with team performance and this association was mediated by information sharing. Demographic diversity moderated the relationship between shared leadership and team performance, such that shared leadership was more strongly associated with team performance in more diverse teams and less in less diverse teams. Research limitations/implications – The results found support for moderating and mediating variables, explaining under what conditions and how shared leadership...
