任务紧迫性下个体情感网络特征、情绪劳动及创新行为的关系研究 总被引：1，自引：0，他引：1
借助情景实验,对任务紧迫性下个体情感网络特征、情绪劳动和个体创新行为之间的作用机理展开研究。结果表明,情感网络中心性在浅层劳动与个体创新行为的关系中起着倒U型调节作用,情感网络中心性在深层劳动与个体创新行为之间起到正向的调节作用。对情绪劳动的合理引导以及对情感网络的有效控制能够充分运用情绪资源的资本优势,促进个体实施创新行为。 相似文献

创新团队中,成员的交互记忆系统反映了团队成员基于对彼此掌握的知识的认知而形成的分工协作机制,对于团队的创新绩效具有重要影响。而团队成员之间的信任关系与网络嵌入特征则是构成了影响交互记忆系统形成与发展的关键因素。本文在探讨交互记忆系统对创新团队绩效作用效果的基础上,重点分析了信任不对称对交互记忆系统的影响机制,并考虑了以团队及成员的网络嵌入特征表现出的在其中的边界效应。本文选择某高校学生组成的移动应用软件项目设计团队开展实验研究。研究发现：首先,交互记忆系统对创新团队绩效具有显著的积极影响,其作用机制可归纳为团队创造力提升、任务效率改善提高和成员满意度改善三条路径;其次,信任不对称不利于交互记忆系统的形成与发展。信任不对称会触发团队成员的知识隐藏行为,不利于对彼此知识的识别、检索和协调,阻碍交互记忆系统的有效运行;再者,成员之间的社会网络具有显著的边界效应。网络中心性能够显著削弱信任不对称对交互记忆系统的抑制作用,但同时降低了交互记忆系统对团队绩效的积极贡献。本文研究结论不仅能够从交互记忆系统视角拓展了创新团队绩效驱动机制的相关研究,还有利于从网络嵌入视角揭示了交互记忆系统驱动创新团队绩效的边界条件,对于提升团队和企业创新绩效具有重要的实践意义。 相似文献

基于社会网络,既有研究在创新团队连接强度与创新绩效关系中忽略了团队外部连接的影响;基于冲突理论,管理学领域认为认知冲突在团队创新过程中属于建设性冲突、情感冲突属于破坏性冲突.明确创新团队内外部连接强度的划分标准,内部连接强度包括正式与非正式沟通程度等,外部连接强度指团队与包括竞争者、合作者、客户等外部组织之间的沟通频率;提出创新团队成员的情感冲突是由认知冲突转变而来的,源自个体的认知冲突及其背景不同.从冲突视角出发,并考虑中国人普遍具有的含蓄特性,以上海汽车集团等5家企业研发团队327名研发人员为例进行实证研究,结果发现:(1)创新团队内外部连接强度正向影响创新绩效;(2)知识创造正向影响创新绩效,且在连接强度与创新绩效中起部分中介作用;(3)认知冲突对连接强度与知识创造的调节作用不显著,情感冲突在连接强度与知识创造路径上起正向调节作用.根据结论,创新团队的内外连接强度、情感冲突、知识创造会对企业创新绩效产生重要影响,为此提出建议:研发团队内部应增强成员间联系,并加强团队整体与外部组织建立合作、相互学习、竞争等关系,以及重视鼓励通过碰撞来激发创新等,以促进组织创造新知识、提高创新绩效. 相似文献

旨在探讨创业团队的内部和外部社会网络对团队创新的互动机制。首先运用典型案例分析法,探索创业团队内部、外部社会网络对团队创新的互动影响机制,以提出相应命题;然后通过大样本问卷调研来对所提假设命题进行检验。研究表明,外部社会网络中的外部联系和外部中心性对创业团队的创新绩效产生积极的影响。在此基础上,验证了创业团队内、外社会网络对创新的交互效应,即内部联系对外部联系与团队创新、外部中心性与团队创新之间的关系具有正向的调节作用。 相似文献

以企业科技创新团队为研究对象,以认知冲突、情感冲突、过程冲突及团队与成员目标冲突为自变量,团队成员所采用的合作冲突管理行为和竞争冲突管理行为为调节变量,以团队绩效为因变量,通过运用实证分析方法,得出当团队成员采取竞争冲突管理行为时,与绩效呈正相关关系的冲突越显著,与绩效呈负相关关系的冲突也越显著;当团队采取合作冲突管理行为时,与绩效呈正相关关系的冲突越显著,与绩效呈负相关关系的冲突越不显著,从而为企业科技创新团队中存在的冲突提供一定的管理借鉴。 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

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

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

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

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
