Drawing on the componential model of creativity (Amabile), we examined how shared leadership and a formally appointed leader's transformational leadership jointly cultivate team creativity in two studies. We conducted an experiment with a sample of 109 undergraduate students (32 teams) enrolled in a business plan competition (Study 1) and a field survey based on multisource, time-lagged data collected from 251 full-time employees working on 64 research and development teams (Study 2). The results from both studies revealed that shared leadership enhanced team members’ individual creative self-efficacy and individual creativity, which in turn improved team creativity. Moreover, the results from Study 2 showed that a formally appointed leader's use of different transformational leadership behaviors had different impacts on individual and team creativity. Individual-focused transformational leadership strengthened the positive effect of shared leadership on team members’ average individual creativity, whereas group-focused transformational leadership facilitated the translation of teams with high average individual creativity into teams with high levels of team creativity. The theoretical and practical implications of the findings are discussed. 相似文献
Given the conceptual differences between different types of job insecurity, it is important to distinguish qualitative job insecurity from quantitative job insecurity when examining their motivational consequences. Building on the approach and avoidance framework, we expect that quantitative job insecurity influences avoid-performance goal orientation (avoidance form of motivation) via psychological safety, whereas qualitative job insecurity influences learning goal orientation (approach form of motivation) via psychological meaningfulness. We also examine the moderating role of organizational justice in such effects. Using two-wave data collected from 281 employees in China, we found that quantitative job insecurity had a positive indirect effect on employee avoid-performance goal orientation via decreased psychological safety, whereas qualitative job insecurity had a negative indirect effect on employee learning goal orientation via decreased psychological meaningfulness. In addition, organizational justice buffered the direct effect of quantitative job insecurity on employee psychological safety and the subsequent indirect effect on employee avoid-performance goal orientation. However, organizational justice did not moderate the influence of qualitative job insecurity on employee outcomes. Our findings provide new insights into the motivational implications of job insecurity.
