Emergence of shared leadership networks in teams: An adaptive process perspective

Adaptive leadership theory suggests that shared leadership networks grow in a complex manner. We propose that leadership decentralization (the dispersion of leadership), leadership density (the total amount of leadership), and situationally-aligned leadership (SAL: leadership transitions to those who fit situation requirements) are distinct aspects of a shared leadership network and should be examined together to capture the development of shared leadership process. Through a study of 450 participants in 90 teams, we find that each of these three aspects of shared leadership plays a different role during shared leadership network emergence. Specifically, transactive memory systems (TMS) contribute to decentralized leadership structures, which in turn precipitate more dense leadership networks. We also find that TMS contributes to the most situationally aligned team member engaging in leadership. Both leadership density and SAL predict team performance. We discuss the theoretical and practical implications of these results.     

Implicit theories of leadership: Stability and change over two decades

Much has changed in the last 20 years, but have people's naïve conceptions of leaders changed as well? Paralleling Offermann et al.'s (1994) study of the content of implicit leadership theories with new samples, the present study investigates ILT stability and change across a 20-year period. Results indicate that, as in 1994, Sensitivity, Dedication, Tyranny, Charisma, Strength, Masculinity, and Intelligence were confirmed as ILT factors. Analyses revealed a new factor, Creativity, and the rearranging of some characteristics across factors. The nine-factor, 46-item scale was confirmed with an independent sample, yielding superior fit indices to the eight-factor solution. This supports the view of ILTs as having both remarkably stable elements despite organizational and societal changes as well as contextually-sensitive elements. Open-ended characteristics had no references to females despite reference to males, as in 1994; thus, “think leader, think male” appears to persist in terms of naïve conceptions of leadership.     

When managers become leaders: The role of manager network centralities,social power,and followers' perception of leadership

We explore how formal managers' centralities in both positive and negative networks predict followers' perceptions of their leadership. By incorporating social networks and social ledger theory with implicit leadership theories (ILTs), we hypothesize that formally assigned group leaders (managers) who have more positive advice ties and fewer negative avoidance ties are more likely to be recognized as leaders by their followers. Further, we posit that managers' informal networks bring them greater social power, an important attribute differentiating leaders from non-leaders. We conducted two survey-based studies in student and field teams to test the hypotheses. Based on nested data in both studies, we found support for our hypotheses. These results remain robust across the two studies even though they used different designs (cross-sectional versus longitudinal), different samples (field versus students) across different countries (United States versus India), and a host of control variables at both the leader and follower levels. We find that managers who are central in the advice network are socially powerful and are seen as leaders by individual followers. In contrast, managers who are avoided by followers lack informal social power are not seen as leaders. We conclude by discussing the theoretical and practical implications of our findings and the ways in which our theory and results extend ILTs and social network theory.     

化被动为主动:共享型领导对员工主动变革行为的影响及作用机制研究

如何让员工将其工作角色外的行为,如主动变革行为,视为其角色内的行为越来越受到学者和管理者的关注。主动变革行为是指个体通过自愿的和建设性的努力来影响组织功能改变的行为,属于一种挑战性的组织公民行为。尽管以往研究对员工主动变革行为的影响因素进行了一些探讨,但主要聚焦于正式垂直领导和个体因素,鲜有研究关注团队情景因素对其的作用效果。通过问卷调查法,以69个部门和262名员工的配对数据为样本,本研究考察了共享型领导对员工主动变革行为的影响及作用机制。跨层次分析结果表明:(1)共享型领导对员工主动变革行为有积极影响;(2)主动变革行为的角色定义与和谐工作激情会分别中介共享型领导与员工主动变革行为之间的关系;(3)领导-成员交换质量会分别调节共享型领导与员工角色宽度自我效能与和谐工作激情之间的关系,领导-成员交换质量越高,共享型领导对员工角色宽度自我效能与和谐工作激情的积极作用越显著;(4)领导-成员交换质量会调节共享型领导通过角色宽度自我效能对员工主动变革行为的间接作用,领导-成员交换质量越高,这一间接作用越显著。     

How (not) to motivate online workers: Two controlled field experiments on leadership in the gig economy

An increasing number of workers participate in online labor markets. In contrast to traditional employment relationships within firms, the interaction between online workers and their employers are short and impersonal, which makes motivating online workers more challenging. We present results from two large-scale controlled field experiments on Amazon Mechanical Turk investigating the effects of monetary rewards and soft leadership techniques on output quantity and quality. In the first study, we investigate the effects of monetary rewards and simple upfront messages (praise or reference points). Monetary rewards increase quantity significantly. Sending simple messages, however, can have a significantly negative effect on quantity. The second study concentrates on the effects of communication based on charismatic leadership techniques. Charismatic communication techniques can also backfire if only a subset of them is used, whereas using a broad set including quantitative goals increases output quantity significantly. Neither intervention had a significant effect on the quality of work.     

Board leadership structure and diversity over CEO time in office: A test of the evolutionary perspective on Italian firms

An evolutionary perspective on CEO-board relations suggests that CEO objectives and interests change over time, and that board roles should shift accordingly, from CEO leadership development during the early stages of CEO time in office toward monitoring during the latest stages. This study examines how two board characteristics, board leadership structure and board diversity, shape innovation investment among Italian firms. Empirical results support the hypothesized effects, suggesting that the board’s effects are contingent upon CEO time in office.
