构建以知识共享和团队创新氛围为中介变量的科研团队信任对团队创新绩效影响的概念模型,以89个科研团队中的545名科研人员为研究样本,利用多层线性回归方法对相关假设进行检验。研究发现:科研团队信任能够显著影响团队整体的创新绩效,且知识共享和团队创新氛围在科研团队信任与团队创新绩效间起中介作用。这表明科研团队管理者应当积极关注团队内部科研人员之间的人际互动因素,重视营造和谐、信任的团队创新氛围,实现团队的知识共享,进而促进整个科研团队的创新绩效不断提升。 相似文献

Although the relationship between social protection and enterprise performance is much debated in the literature, evidence is particularly limited in the case of small and medium-sized enterprises in developing economies. Using census data from 2010 to 2014, this article examines how the provision of social security influenced business performance in Indonesia. The author finds that increased social security spending of 10 per cent is associated with a per-worker revenue gain of up to 2 per cent. Moreover, profits are not found to decrease with increased social protection coverage, suggesting that increasing worker benefits may be a worthwhile business investment. 相似文献

We move beyond the performance returns of individuals’ direct network connections to study the effects of “secondhand” social capital, i.e., from the networks of one’s contacts. We propose that certain colleagues may be more valuable to one’s job performance than others when their spillovers of novel information combine with spillovers of the cooperation needed to obtain that novelty. In a study of 1273 research and development employees across 16 business units, we find that the most benefit to one’s own performance comes from having ties that span business units and that also include secondhand closure (i.e., where one’s contacts are each embedded in a constrained, dense network). Bridging the organizational boundary provides the novelty; and secondhand closure provides the cooperation. Further, by examining who in the network is constraining these contacts, we are able to trace their cooperative motivation both to reputational and organizational identity concerns, which each create a spillover of cooperation toward the focal individual, who reaps the returns. 相似文献

The feasibility of microfinance institutions (MFIs) to expand outreach to the poorest while remaining financially sustainable has long been debated. Using data from 206 MFIs in 33 African countries, we adopt the three‐stage least square technique to assess whether a trade‐off exists between sustainability and outreach depth. Our results confirm the existence of a trade‐off. The evidence also supports ongoing subsidies for MFIs with the aim of encouraging outreach. In addition, we examine whether there is an inflection point beyond which higher interest rates reduce profitability for MFIs. We find no evidence of a threshold beyond which profitability is reduced. 相似文献

How does servant leaders' unique ability to place each follower's needs above their own influence relationships between followers and impact their collective performance? In a study that integrates principles of servant leadership with the social comparison theoretical framework, we tested a group-level model to examine how servant leadership induces low perceived differentiation in leader-member relationship quality (perceived LMX differentiation) within a group, which strengthens team cohesion and in turn positively influences team task performance and service-oriented organizational citizenship behaviors (service OCB). Our sample comprised 229 employees nested in 67 work teams. Structural equation modeling results indicate that servant leadership significantly predicts low perceived LMX differentiation; perceived LMX differentiation is strongly related to team cohesion such that the lower the perceived differentiation, the stronger the team's cohesiveness. And, team cohesion is also strongly related to both the team's task performance and service OCB. Perceived LMX differentiation and team cohesion mediate the effect of servant leadership on both team task performance and service OCB. 相似文献

In the current investigation, idiosyncratic deals (i-deals; individualized work arrangements) are modeled as differentiated resources that shape leader-member exchange (LMX) relationships in workgroups. We integrate literature on leader-member exchange (LMX) with research on i-deals to argue that employee evaluations of i-deals received from the grantor –typically the leader- enhance employee perceptions of LMX, which in turn become instrumental in generating positive performance outcomes. Furthermore, because workgroup characteristics have potential implications on the relationship between a deal grantor and the deal recipient, drawing upon social identity theory of leadership, we reason that the i-deals-LMX relationship is affected by the overall value congruence among the group members. Cross-level moderated mediation analyses on multi source data obtained from 289 employees nested in 60 workgroups showed that the mediational role of LMX in the i-deals to performance outcomes relationship was weaker in high value congruence groups. 相似文献

歌唱是情感的艺术,以声传情,以情动人,情声交融,声情并茂是歌唱者追求的理想目标。但也有不少歌者舍本逐末.一味追求声音的炫技或表演的花哨,以至于所唱之曲难有动人心扉之妙。从情与声的关系展开分析,就如何才能以声传情、声情并茂等问题进行探讨,以期帮助歌唱者树立良好歌唱理念。 相似文献
