企业科研人员的创新工作对于企业的长期生存与发展至关重要,因此,如何提高科研人员的创新绩效已经成为当前企业迫切需要解决的问题。在文献回顾的基础上,通过对20家高科技企业的356名科研人员及其直接主管的配对数据进行相关、回归分析,检验包容性领导、责任心以及主管信任对科研人员创新绩效影响的一个有中介的调节作用模型。研究结果表明,包容性领导对科研人员创新绩效具有显著正向影响;责任心显著调节包容性领导与科研人员创新绩效之间的关系;而且,责任心对包容性领导与科研人员创新绩效之间的调节作用以主管信任为中介。研究结论丰富了领导风格与员工创新等方面的研究,并对企业提高员工创新绩效具有实践上的指导意义。 相似文献

本研究以心理契约与社会交换理论为基础,探讨组织变革感知、心理契约违背与员工创新绩效间的作用机制。研究结果发现:员工的组织变革感知对心理契约违背具有正向效应,而对知识创造绩效具有负向作用,心理契约违背既是中介变量同时也对知识创造绩效具有消极影响;在员工感知组织干预措施中,除组织沟通感知对它们之间关系的调节作用不明显外,员工参与感知与员工培训感知皆对它们具有调节作用。 相似文献

知识共享是组织开发知识资源以增强竞争优势的关键环节。尽管以往研究表明，多种领导风格显著影响了员工知识共享，但目前对包容性领导是否影响、如何影响以及何种情况下更能影响员工知识共享却知之甚少。基于185份科研人员的有效调查问卷数据，考察了包容性领导对员工知识共享的影响效果，尤其是内部人身份认知的中介作用和组织创新氛围的正向调节作用。实证检验结果显示：包容性领导显著正向影响员工知识共享；内部人身份认知在包容性领导与员工知识共享之间发挥中介作用，且组织创新氛围将强化内部人身份认知在包容性领导与员工知识共享两者关系之间的中介作用；组织创新氛围越强，包容性领导对员工知识共享的正向影响以及内部人身份认知对员工知识共享的正向影响亦将随之增强。 相似文献

现有文献就包容性领导对员工创新行为的直接影响开展了较多研究,鲜有研究涉及其内在的作用机制。以心理可得性、追随力和核心自我评价为中介变量,互动公平为调节变量,构建了基于多重中介变量和单元调节变量的包容性领导对员工创新行为的多链条作用机制的理论概念模型。基于问卷调查数据开展的实证分析结果表明:包容性领导对员工创新行为有显著正向促进作用,心理可得性、追随力和核心自我评价均是包容性领导与员工创新行为关系之间的部分中介变量,互动公平显著正向调节心理可得性与员工创新行为间的关系。 相似文献

A research 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 in red wine-can improve the sensitivity of mice to the hormone insulin according to a report in the October issue of Cell Metabolism.…… 《中国科学院院刊(英文版)》2008,22(1):14-15
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

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

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

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
