本文对我国科研人员职业生涯的成长轨迹与影响因素开展定量研究,以科研人员获得博士学位的时间为基点,采用事件史分析方法分析科研人员职业生涯中的若干重要节点和事件,包括职称晋升、第一次重要学术产出、第一次获得荣誉奖励以及第一次担任行政或学术职务等关键事件。在此基础上,进一步分析个人家庭因素（性别、孩子状况和配偶文化）、教育背景因素（毕业院校、导师身份和博士后经历）以及社会环境因素（工作单位、流动状况和学科领域）等对科研人员职业生涯成长的影响状况。结果发现,科研人员职业生涯成长过程中的“累积效应”依然明显,如毕业院校、博士后经历等教育背景都会对科研人员职业生涯的成长产生正向影响;师承效应在科研人员职业生涯发展中发挥重要作用;流动经历增加了科研人员进入到职业生涯中的关键事件比例等。基于研究结果,文章最后提出如何更好的促进科研人员成长的政策建议。 相似文献

大学生的成长环境对其人格和心理健康水平具有重要影响。针对目前我国大学生心理健康状况，从大学生入学前所处的家庭生活环境和入学后的大学生活环境入手，具体调查了大学生的家庭背景、人际交往、情绪、情感等方面，发现大学生成长的家庭环境和学习生活环境对大学生的心理健康具有直接影响。搞清大学生的成长环境和心理健康之间的规律是做好大学生心理健康工作和思想政治工作的关键，也是培养大学生成才的关键。 相似文献

中国工程院院士作为中国战略科技人才的代表群体，为中国科学智库的建设和战略科技决策提供支撑。本文以2015—2021年间增选的中国工程院院士为研究对象，收集其中281名院士在3个成长阶段中的流动数据，包括籍贯地到本科就读地，首次就业地与最高学历就读地间和就业地间的流动，采用社会网络分析法对3个流动网络进行分析。结果表明，随着院士成长阶段的推移，院士流动趋于稳定，北京逐渐成为全国院士流动网络的核心，省级行政区对院士的吸引力受到当地高等教育水平的影响。据此，本文从政府部门，高校、科研院所和科技企业，以及战略科技人才自身3个方面提出战略科技人才培养和保留的对策建议。 相似文献

长江学者特聘教授是高校高层次人才的杰出代表,其成长规律已成为多学科关注的焦点问题。本研究以1998-2016年度高校长江学者特聘教授为研究对象,选取其中367名特聘教授的履历信息并对其进行深度编码,利用生存分析法动态考察其成长规律及影响因素。研究发现,长江学者特聘教授总体发展趋势上存在年龄、学科和地域分布差异特征;Kaplan-Meier分析表明,多样化教育背景下培养的人才进入副教授和教授阶段的风险率较高,意味着生存率较低,存活时间较短,可加快其职业晋升速度,而单一化教育背景的作用则相反;COX结果显示,年龄降低了副教授、教授阶段的生存风险并因而延缓职业成长,留学经历增加了副教授阶段的生存风险并进而提高了职业成长速度,博士后经历则降低了生存风险并因而减慢了职业成长速度。文章最后讨论了本研究的理论意义和实践启示。 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
