为探索国家启动科技人才队伍建设计划以来区域科技人才开放效率的时空变异特征和规律，采用考虑非期望产出的SBM模型、DEA-Malmquist模型、Moran’Ⅰ模型，从静动态视角测度和剖析中国区域科技人才开放效率的时空变化和空间相关性特点，并采用空间计量模型进行空间溢出效应验证。研究结果表明，从静态来看，2016年后越来越多地区科技人才开放效率值达到有效水平；从动态来看，Malmquist生产率总体上升1.1%,2015年后科技人才开放效率值均明显改善；总体上，科技人才开放效率表现出空间集聚性和相关性较弱的特征，在直接效应层面，经济发展水平、制度环境、金融支持对科技人才开发效率均具有显著正相关特征。基于此，提出提升区域科技人才开放水平的政策建议。 相似文献

结合我国科技人才发展实际,从科技人才规模、结构、投入、产出和环境5个维度出发,构建我国科技人才竞争力评价指标体系,在此基础上,利用主成分分析法对我国31个省市2011—2015年科技人才竞争力进行评价与比较,发现广东省科技人才竞争力总体优势明显,居全国第三,且近年来综合竞争力在各省市中有缓慢上升的趋势。从各主成分看,广东省科技人才投入竞争力和人才环境竞争力排名靠前,但科技人才资源竞争力明显不强,与北京、江苏等省市相比还有较大差距,为此,提出进一步提升广东科技人才竞争力的对策。 相似文献

目前有关科技人才、科技创新与经济发展之间关系的研究主要集中在影响效应和协同效应两个方面。为深入揭示江苏省人才链、创新链和产业链之间的内在联系，以科技人才、科技创新和经济发展3个子系统及其构成的综合发展系统为研究对象，构建江苏省综合发展系统协同度评价指标体系，并基于其2011—2020年相关数据，运用复合系统静态协同度模型和动态变化综合效度评价模型计算各系统协同度发展水平及其变化速度的状态和趋势。结果发现：江苏省综合发展系统相同基期的静态协同度逐年递增，但并未达到高级协同等级；3个子系统具有相互协同的作用，但长期处于低度协同演变状态，协同效应并不稳定，其中科技人才子系统是造成不稳定的主要因素；科技人才结构、研究机构数量、第三产业占比和高新技术企业占比分别是影响科技人才子系统、科技创新子系统和经济发展子系统协同发展的关键因素；各系统协同速度发展趋势呈现不规律波动状态。基于此，提出江苏省政府应建立信息公开、资源共享、部门联动等促进有效协同发展机制，加强人才结构优化，调动企业研发积极性促进人才链、创新链、产业链融合发展，以及注意兼顾各系统协同发展状态与速度等对策建议，以促进实现科技人才、科技创... 相似文献

基于Cobb-Douglas生产函数构建面板数据模型,对科技人才集聚、产业集聚及其交互作用对区域创新能力的影响进行了实证研究。研究发现,制造业集聚和生产性服务业集聚都与科技人才集聚形成正向的交互效应,推动区域创新能力的提升。科技人才集聚对于区域创新能力的贡献更大,科技人才集聚对区域创新能力的影响显著为正,而产业协同集聚的效应则显著为负,产业协同集聚对区域创新能力影响存在门槛效应,当科技人才集聚的对数值超过0.254 3时,产业协同集聚对区域创新能力的总效应为正,低于0.254 3时,产业协同集聚则对区域创新起着抑制的作用。 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

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
