Existing models have not adequately accounted for the leadership of scientists and engineers engaged in creative work. In this Incubator, we present a model of creative leadership of scientists and engineers and argue that such leaders should possess expertise in three vectors. Implications and directions for future research are discussed. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

In this theory-driven literature review we examine how leadership and emerging research in positive organizational behaviour (POB) may inform our understanding of human mechanisms that affect safety outcomes. According to authentic leadership theory, leader self-awareness and self-regulation processes are vital mechanisms in the leader-follower exchange. From emerging research on authentic leadership, we propose that production management values, attitudes, and behaviour are linked to safety climate and safety outcomes in safety critical organizations (SCOs). According to recent developments in management theory, “psychological capital” is comprised of four distinct aspects that can be linked to desirable organizational outcomes and sustained high quality performance in individual workers. From this we offer a research model and five research propositions implicating that authentic leadership directly affects safety outcomes via promoting positive safety climate perceptions. Furthermore, we propose a second path where psychological capital mediates the relationship between authentic leadership, safety climate and safety outcomes in SCOs. 相似文献

Drawing on the perceived organizational membership theoretical framework and the social identity view of dissonance theory, I examined in this study the dynamics of the relationship between psychological contract breach and organizational identification. I included group‐level transformational and transactional leadership as well as procedural justice in the hypothesized model as key antecedents for organizational membership processes. I further explored the mediating role of psychological contract breach in the relationship between leadership, procedural justice climate, and organizational identification and proposed separateness–connectedness self‐schema as an important moderator of the above mediated relationship. Hierarchical linear modeling results from a sample of 864 employees from 162 work units in 10 Greek organizations indicated that employees' perception of psychological contract breach negatively affected their organizational identification. I also found psychological contract breach to mediate the impact of transformational and transactional leadership on organizational identification. Results further provided support for moderated mediation and showed that the indirect effects of transformational and transactional leadership on identification through psychological contract breach were stronger for employees with a low connectedness self‐schema.

Although transformational leadership has been investigated in connection with change at higher levels of organizations, less is known about its “in‐the‐trenches” impact. We examined relations among transformational leadership, explicit change reactions (i.e., relationship quality), change frequency, and change consequences (i.e., task performance and organizational citizenship behavior (OCB)) during continuous incremental organizational change at lower hierarchical levels. In a sample of 251 employees and their 78 managers, analyses revealed that the quality of relationships between leaders and employees mediated the influence of transformational leadership on employee task performance and OCB. We also found that change frequency moderated the positive association of relationship quality with task performance and OCB, such that associations were stronger when change frequency was high.

The following article examines Haiti's past, present and future sustainability based on a thorough cause and effect analysis of the country's current situation, research on relevant social and economic factors, years of field experience, as well as training and consulting for businesses, political parties and non-profit organisations. In addition to identifying the current major core conflicts of Haiti, the article also suggests solutions to various social, economical and environmental issues. 相似文献

The extant literature on the relationship between self‐sacrificial leadership and subordinate behavioral outcomes has primarily focused on the influence of this leadership on subordinate affiliative behaviors. Our research proposed a theoretical model explaining why and when self‐sacrificial leadership might promote taking charge, an exemplar of challenging behaviors. We tested this model across two studies conducted in China. In addition, we also examined the differences in the boundary conditions for self‐sacrificial leadership to influence taking charge and affiliative behaviors (cooperation in Study 1 and helping in Study 2 ). Our results revealed that (i) self‐sacrificial leadership was positively related to subordinate taking charge, with organizational identification acting as a mediator for this relationship, and (ii) risk aversion moderated both the self‐sacrificial leadership–subordinate taking charge relationship and the mediating effect of organizational identification, such that the relationship and its mediating mechanism were weaker for subordinates high rather than low in risk aversion. These moderating effects, however, could not generalize to cooperation and helping. Finally, the theoretical and practical implications of our results and directions for future research were discussed. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献
