团队知识共享对提升团队的效率至关重要,如何促进团队知识共享也成为当下的研究热点之一。从线上与线下两个维度,对高校研究生科研团队内部的知识共享行为进行量化分析及对比研究,并进一步对情感信任这一知识共享行为的影响因素进行深入探讨。在构建理论模型的基础上,对通过问卷调查所收集的有效数据进行了分析,研究结果表明,线上知识共享行为与线下知识共享行为存在一定程度的相关性;与线下方式相比,线上方式更有助于提高成员之间知识共享的广度和深度;情感信任会同时对线上与线下的知识共享行为产生正向影响,相比较而言对线下的共享行为影响程度更大。 相似文献

采用现场调查方法,以湖南、湖北、福建、广东和浙江等地企事业单位614名员工、93个不同职能的工作团队为研究对象,分析探讨了员工建言行为对团队创造力的影响及其内在的认知作用机制。研究结果表明：员工建言行为对团队创造力有显著的正向影响,交互记忆系统中的专长和信任维度采用现场调查方法,以湘、鄂、闽、粤和浙等地企事业单位614名员工、93个团队为对象,应用多元回归方法探讨了员工建言对团队创造力的影响。研究发现：员工建言对团队创造力有显著的影响,交互记忆系统中的专长和信任维度在员工建言与团队创造力之间有部分中介作用,而知识共享则有完全中介效应,团队学习行为在员工建言对团队创造力作用中有正向调节效应。在两条作用路径中,团队学习行为越高,员工建言对交互记忆系统（知识共享）的积极作用越大,进而对团队创造力的影响越强。 相似文献

采用结构方程模型分析了变革型领导、信任倾向、团队知识共享绩效的不同维度之间的关系,研究的样本包括791份有效问卷以及所对应的环境状况.研究结果表明,变革型领导通过信任倾向作为中介变量对团队知识共享绩效具有显著的影响作用;信任倾向在变革型领导与团队知识共享绩效之间起到部分中介作用;任务导向和关系导向的变革型领导对信任倾向和团队知识共享绩效的不同维度产生影响作用的路径是不同的,任务导向的变革型领导对共享意愿、共享行为、共享绩效有显著影响,关系导向的变革型领导对信任倾向、员工满意有显著影响. 相似文献

论文把团队知识异质性分为团队显性知识异质性、团队伪隐性知识异质性、团队真隐性知识异质性,研究了其通过团队互动与团队创新绩效的关系。实证结果表明团队显性知识异质性通过团队互动最终影响团队创新绩效的作用并不显著;团队伪隐性知识的异质性对于团队沟通、团队知识共享、工作冲突、团队协作有显著的正向影响,且最终促进了团队创新绩效;团队真隐性知识异质性阻碍了知识共享,引发了团队人际冲突,这些都阻碍了团队创新。调节变量作用分析结果表明,团队信任能够显著调节团队沟通、知识共享、人际冲突、工作冲突、团队协作对创新绩效的影响关系。 相似文献

以往对于真实型领导和创造力的关系研究缺少以积极氛围为中介去探索。本研究以中国本土企业的69个团队领导者和335名团队成员为样本,实证检验了真实型领导对下属创造力的影响过程。研究结果表明,真实型领导正向影响团队信任氛围和心理氛围,并通过这两个中介变量正向影响个体知识共享行为和创造力,而且知识共享对创造力具有显著影响。因此,为提高员工的创造力,领导者不仅需要塑造自身的真实型领导风格,而且需要努力为下属营造一种基于信任和心理安全的团队氛围。本文对领导行为理论和领导实践具有重要启示作用。 相似文献

以我国高新技术企业为例,对团队内成员间的知识分享行为及其影响因素进行实证研究。研究发现,团队成员间的共享心智模式能够引导成员在所需的情境中与其他成员进行互动,对知识分享行为具有显著的正向影响效果,而这种影响效果会受到成员性格特征的调节影响。因此在团队运作过程中,团队领导者若能通过详细的任务说明以及增进成员的互动等方式,让不同性格的团队成员具有相匹配的心智模式,将有助于团队知识分享行为的产生。 相似文献

Aresearch group led by Prof. ZHAI Qiwei from the Institute for Nutritional Sciences under the CAS Shanghai Institutes for Biological Sciences has discovered that even relatively low doses of resveratrol--a chemical found in the skins of red grapes and in red wine--can improve the sensitivity of mice to the hormone insulin, according to a report in the October,2007 issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of Type 2 diabetes, the findings“provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said. 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

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

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

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

This essay focuses on universal service and the Internet as means to support social and political participation. The emphasis on access to telecommunications systems in conventional approaches to universal service is contrasted with access to content. A model of the information environment is described that accounts for the roles of content and conduit, both of which are necessary conditions to achieve true access. A method is outlined for employing information indicators to observe or measure the information environment. 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
