This study tests how transformational leadership fosters team performance through team cohesion and how that relationship is moderated by previous team performance and leadership consensus. We computed a moderated-mediation model based on a sample of 690 professional players in 59 top professional teams in interactive team sports leagues (basketball, handball, roller hockey, and indoor football/soccer) in Spain. Our findings suggest that transformational leadership indirectly influences objective team performance through the mediation role of team cohesion and that this indirect effect is more prominent when the level of previous performance is higher. We also found that the indirect effect of transformational leadership on team performance via cohesion is stronger in teams with higher consensus regarding their coaches' leadership. Overall, our results demonstrate the importance of integrating dispersion and contextual variables into research models, in particular, previous performance and leadership consensus. 相似文献

We studied the immunglobulin synthesis of peripheral blood lymphocytes of healthy blood donors and of patients suffering from acute schizophrenia and endogenous depression. The detection of cytoplasmic immunglobulins was performed by immunofluorescence. The schizophrenic patients showed an increased immunglobulin synthesis without cultivation of lymphocytes, after cultivation for 7 days and after pokeweed mitogen stimulation. This activation of B cells could be the result of disturbances in the prostaglandin formation and activation. 相似文献
