Entrepreneurial teams often struggle with simultaneous task and team challenges at an early stage of new venture creation. The way in which teams shape their teamwork is key in leveraging performance in the pre‐founding phase. Learning should help the team in establishing good teamwork and in expanding its members’ entrepreneurial capabilities. Leadership is needed to facilitate and guide this learning. Accordingly, we investigated learning and leadership as facilitators of performance in the pre‐founding phase. Specifically, we examined team reflexivity as a collective internal learning process and boundary spanning behaviour as an externally directed individual activity, operating at different levels in fostering team and individual performance. Charismatic team leadership was examined as a catalyst of learning, shaping team and individual performance ultimately. The multilevel mediation model was tested based on data from 196 members of 58 teams of a venture creation programme. Team reflexivity predicted team and individual performance. Boundary spanning behaviour was not related to performance. As hypothesised, charismatic team leadership predicted team and individual performance, both mediated by team reflexivity. This research highlights the relevance of team learning in pre‐founding teams and emphasises leadership in shaping learning and moving new ventures forward.  相似文献

The study examined whether a behavior-change intervention focusing on self-regulatory strategies and emphasizing role model support increases physical activity (PA) among insufficiently active (not meeting PA guidelines of 150 min/week) cancer patients. Ambulatory cancer patients [N = 72; 54% female; M = 56 years, SD = 12.34; most with breast or colon cancer (34, 15%)] were enrolled in the MOTIVACTION-study, a 4-week intervention (1-hr counseling, followed by weekly phone calls), with pretest (T1), posttest (T2) and a 10-week follow-up (T3). Participants were randomized to either an exercise or to a stress management intervention (active control). The exercise intervention emphasized self-regulatory strategies (e.g. action- and coping planning and self-monitoring); patients were also encouraged to contact a physically active same-sex role model as a potential exercise partner. The active control condition consisted of coping and relaxation techniques. Sixty-seven patients remained in the study and completed the SQUASH assessment of PA and a measure of perceived stress. PA was validated by Actigraph accelerometry. At T2, 46% of the patients in the exercise group and 19% of stress management patients increased their activity levels to meet PA guidelines (>150 min/week; χ2(1) = 5.51, p = .019). At T3, participants in the exercise intervention maintained their exercise level (46%), but also 31% of the stress management patients met the guidelines. All patients reported reductions in perceived stress. Additional analyses comparing patients in the exercise group by role model contact (63% realized contact) revealed that those who had contact with their role model were significantly more likely to adhere to the recommended guidelines (T2:50%; T3:64%) compared to those who did not have contact with a role model (T2:39%; T3:15%), suggesting the potential of mobilizing role model support to facilitate PA. In sum, cancer patients may not only benefit from an exercise intervention emphasizing self-regulation, but also from stress management, regarding both reducing stress and increasing PA.  相似文献
