This study examined how leaders’ internal and external activities mediate the relationship of functional heterogeneity and interteam goal interdependence to team effectiveness (in-role performance and innovation) in interdisciplinary teams. The results of the structural equation model from a sample of 92 interdisciplinary teams indicate that leaders’ internal activities fully mediate the relationship of team functional heterogeneity and interteam goal interdependence to team in-role performance. The leaders’ external activities were found to fully mediate the relationship of interteam goal interdependence to team innovation. We discuss the implications of these findings for both theory and practice.

The call for a more holistic approach to cope with school violence motivated the present study. The present model postulates that effective teamwork at the school management team level can have a positive impact on the level of school violence. Specifically, the model examined the mediating role of school management team effectiveness (in-role performance and innovation) in the relationship between the organizational-level factors of principals’ internal and external boundary activities and school violence. Data was collected from a survey of 692 school members and 92 principals in Israel. The structural equation model confirmed the main hypotheses and indicated that school management team effectiveness fully mediated the relationship of principals’ internal boundary activities to school violence. These results carry important practical implications for policymakers to help schools manage school violence issues. Understanding how the principals’ boundary activities can enhance school management team effectiveness by facilitating improved knowledge exchange and social relationships is important and may provide a mechanism to decrease school violence. The implications of these findings for both theory and practice are discussed.

Purpose As a result of continuous reforms, increased emphasis has been placed on participative leadership as a means to improving school and teacher outcomes. However, along with the benefits of participative leadership comes the potential for strain and burnout, which stem from work intensification. Applying the implicit leadership theory and the conservation of resources theory, the purpose of this paper is to propose that differences in school’s cultural attributes will influence the emergence of participative leaders and their influence on teachers’ outcomes of job satisfaction and burnout. Design/methodology/approach Data were collected by survey from a sample of 367 teachers in Israel. Findings First, the results of general linear model (GLM) analysis indicated significant differences in the teachers’ perceptions of participative leadership between schools characterized by different cultural attributes. Second, the results of GLM indicated significant differences in the effects of participative leadership on teacher burnout across schools characterized by different cultural attributes. Originality/value This study has implications for policies involving the design and implementation of leadership tools for school management. Although research has emphasized the relationship between stressful job conditions associated with shared decision making and teachers’ well-being and job satisfaction, the volume of comparative work in the educational field shedding light on the impact of school’s cultural attributes on this question is limited. This study may assist principals in making their schools both more effective and more responsive to teacher expectations.
