谦卑领导行为和团队创新都是近年来广受关注的研究问题,虽然关于两者各自的研究较多,但尚未见到对他们之间关系的探讨。基于58个团队270名员工及其直属领导的配对样本,探讨了谦卑领导行为对团队创新的作用机制及其边界条件。结果表明,谦卑领导行为对团队创新具有显著的正向影响;团队行为整合在谦卑领导行为与团队创新关系中起中介作用;团队分配公平感在谦卑领导行为与团队行为整合的关系中起正向调节作用,并且进一步调节了团队行为整合在谦卑领导行为—团队创新关系中的中介作用,即在团队分配公平感高的情况下,团队行为整合中介谦卑领导行为与团队创新之间的关系。 相似文献

面对日益VUCA的竞争环境,创新成为组织生存发展的现实选择,而团队是组织正常运作的基本单元,团队创新是组织目标实现与竞争优势维系的重中之重,而跨界整合的移动互联时代,团队仅靠自身资源难以应对,因而如何获取外部资源、开发内部资源与整合内外资源成为团队创新的关键,而跨界行为是团队资源外部获取、内部开发与内外整合的可行选择,因而如何通过跨界行为提升团队创新已然成为业界实践与学界研究亟待解决的问题。基于此,本研究以资源依赖理论为基础,旨在探究团队实施的整合共享型人力资源实践（IS-HRP）对团队创新绩效的影响机制与边界条件。基于312份团队领导样本纵向追踪的实证研究发现：（1）IS-HRP与团队创新绩效显著正相关;（2）团队跨界行为在IS-HRP与团队创新绩效影响间有中介作用;（3）包容型领导正向调节IS-HRP与团队创新绩效间关系以及团队跨界行为与团队创新绩效间关系;（4）包容型领导调节IS-HRP通过跨界行为对团队创新绩效的间接作用,包容型领导水平越高,其间接作用越强。从而为团队创新绩效提升的管理实践、领导风格与团队行为提供了理论依据与决策借鉴。 相似文献

组织越来越趋于团队工作模式,更高的团队绩效依赖于团队中的知识共享.而共享领导和交互记忆系统(transactive memory system,TMS)是影响团队知识共享的两大重要因素.探讨了共享领导、TMS和团队知识共享之间的关系,并提出了假设模型.认为TMS在共享领导和团队知识共享之间起中介作用,共享领导对TMS具有正向促进作用,并直接和间接通过TMS正向影响团队知识共享,为建设高绩效团队提供理论指导. 相似文献

This study examined how students who had no prior experience with videoconferencing would react to the use of videoconferencing as an instructional medium. Students enrolled in seven different courses completed a questionnaire at the beginning of the semester and again at the end of the semester. Students at the origination and remote sites did not differ in their reactions toward videoconferencing but there was a significant difference for gender. Women reacted less favorably to videoconferencing. Compared to the beginning of the semester, students reported significantly less positive attitudes toward taking a course through videoconferencing at the end of the semester. There were no significant differences in students' attitudes toward videoconferencing across courses at the beginning of the semester but there were significant differences across the courses at the end of the semester. The results suggest the need for better preparation for both students and instructors. 相似文献

With great care, Dr. ZHOU Zhonghe takes out a package wrapped by cotton tissue from a drawer and says: "This is the gem of our collections: the fossil of a bird that lived 125 million years ago!" Then, pointing at a tiny mound, he explains: "Look, this is the claw and that is the head. It was in the egg shell and ready to hatch ... The species fell into a family of waterside inhabitants." 相似文献

A computer-mediated group is a complex entity whose members exchange many types of information via multiple means of communication in pursuit of goals specific to their environment. Over time, they coordinate technical features of media with locally enacted use to achieve a viable working arrangement. To explore this complex interaction, a case study is presented of the social networks of interactions and media use among members of a class of computer-supported distance learners. Results show how group structures associated with project teams dominated who communicated with whom, about what, and via which media over the term, and how media came to occupy their own communication niches: Webboard for diffuse class-wide communication; Internet Relay Chat more to named others but still for general communication across the class; and e-mail primarily for intrateam communication. Face-to-face interaction, occurring only during a short on-campus session, appears to have had a catalytic effect on social and emotional exchanges. Results suggest the need to structure exchanges to balance class-wide sharing of ideas with subgroup interactions that facilitate project completion, and to provide media that support these two modes of interaction. 相似文献

Electronic data interchange (EDI) provides means for interorganizational communication, creates network externalities, requires an advanced information technology (IT) infrastructure, and relies on standards. In the diffusion of such innovations, institutional involvement is imperative. Such institutions contain governmental agencies, national and global standardization organizations, local government, and nonprofit private organizations like industry associations. The last type of organizations we call intermediating institutions. They intermediate or coordinate ("inscribe") the activities of a group of would-be adopters. Unfortunately, little is known of how these organizations shape the EDI diffusion trajectory. In this article we examine one specific type of intermediating organizations?industry associations?and how they advanced the EDI diffusion process in the grocery sectors of Hong Kong, Denmark and Finland. We identify six institutional measures, placed into a matrix formed by the mode of involvement (influence vs. regulation) and the type of diffusion force (supply push vs. demand pull), that can be mobilized to further the EDI diffusion. Industry associations were found to be active users of all these measures to varying degrees. Their role was critical especially in knowledge building, knowledge deployment, and standard setting. Furthermore, institutional involvement varied due to policy and cultural contingencies and power dependencies. 相似文献

The increasing prospects of digital piracy has prompted the perceived need by electronic publishers to adopt technical systems of protection, and governments to reform their copyright laws. This article is a preliminary study of the management of intellectual property by electronic publishers, defined as those involved in the production of online databases, and CD-ROMs. It focuses on three main issues: (1) how electronic publishers view the increasing threat of piracy; (2) the methods of protection employed to protect intellectual property in digital format; and (3) the importance of technological protection of intellectual property in electronic publications. The analysis is based on a sample of 23 UK electronic publishers. The interviews revealed an interesting assortment of protection methods and did not show that technological protection was a preferred way. Instead, the means of protection, in addition to copyright law, comprised niche markets, pricing, trust, bad publicity, and nontechnical and technical means. 相似文献

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

Prof. SUN Changpu from the CAS Institute of Theoretical Physics coworkers from University of Basel in Switzerland have worked out a way - at least in theory - to split a beam of molecules according to their chirality. The technique involves passing the molecules through three different laser beams is similar to the famous Stern-Gerlach effect whereby a beam of atoms passing through a magnetic field is split in two according to the atoms' spin states 《中国科学院院刊(英文版)》2008,22(1):23-23
