【目的】 了解我国英文科技期刊学科分布情况,为创办英文科技期刊提供学科方向参考。【方法】 基于Web of ScienceTM(WoS)学科分类,利用InCites数据库对各学科及期刊2016—2017年发文情况进行分析。【结果】 WoS共有252个学科,其中自然科学有176个学科,我国在144个自然科学学科中有相关期刊被SCI收录,其他32个学科还没有相关期刊被SCI收录。在还没有相关期刊被SCI收录的32个学科中,我国学者在其中17个学科的SCI收录期刊的发文量超过1000篇;在有相关期刊被SCI收录的144个学科中,我国学者发文量在2000篇以上且在我国期刊发文量占在全球期刊发文量的比例低于3%的学科有45个。【结论】 我国英文科技期刊的发展远远落后于科研水平的提升,不足以支撑科研论文的发表,建议加快创办英文期刊的进程,加大创刊力度,填补学科空白。  相似文献

【目的】客观评估与分析我国中英文化学科技期刊在国内国际的影响力,并据此提出中国化学科技期刊现阶段发展的建议。【方法】以中国16种SCI收录的化学期刊为样本,采用文献计量学方法分析其2011—2020年在JCR、CJCR、CSCD-JCR 3个数据库的定量指标,包括影响因子(Impact Factor,IF)、总被引频次(Total Cites,TC)、自(被)引率或他引率等。【结果】JCR收录期刊的IF、TC与自引率等数据反映出近10年来我国英文化学科技期刊国际影响力明显提升,中文科技期刊国际影响力略有提升。CJCR与CSCD-JCR收录期刊的相应指标反映出近10年来中文科技期刊在国内具有高影响力的优势在减弱,2016—2020年英文化学科技期刊国内影响力明显提升。【结论】建议重视规划中文化学科技期刊的发展、优化现有英文化学科技期刊的结构以及新创办化学二级或交叉领域英文期刊以扩大该学科期刊方阵,促进我国中英文化学科技期刊全面深入的发展以及在国内国际的影响力大幅度提升。  相似文献

【目的】 研究中国高校主办的SCI收录期刊对基本科学指标(Essential Science Indicators,ESI)学科发展的贡献度。【方法】 利用ESI和InCites数据库,研究2007—2017年高校主办的42种SCI收录期刊对ESI学科的贡献度。【结果】 高校主办的SCI收录期刊从发文量和被引频次两个方面对其高校ESI学科建设作出较大贡献,但整体而言期刊的学术影响力落后于学科发展。【结论】 高校主办SCI收录期刊的影响力有待提高,以更好地助力学科建设;高校可进行综合性学报改革,以提升高校主办期刊的专业影响力,也可依托ESI学科优势创办新刊,填补ESI学科空白。  相似文献

【目的】了解目前中国SCI期刊总体表现以及与国外出版平台的合作情况,为中国英文科技期刊平台建设,以及国外出版商的挑选提供参考。【方法】以同时被SCI和《中科院期刊分区表》收录的中国科技期刊为数据源,对比分析相关学科期刊,以及不同出版平台的SCI期刊的表现。【结果】总体上,中国大部分SCI期刊的影响因子及发文量较低,其中,与国际出版平台合作的SCI期刊表现相对更好,国内期刊平台建设相对较弱,不少出版社开始由"借船出海"转向"造船出海",着力打造自己的国际出版平台。【结论】中国SCI期刊实力总体偏弱且学科覆盖度不高,借船出海仍是目前提升中国科技期刊影响力较为有效的方式,而打造我国自己的国际出版平台的需求日益凸显。  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

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

Ajoint study by Prof. ZHANG Zhibin from the CAS Institute of Zoology and his co-workers from Norway, US and Swiss have indicated that historical outbreaks of migratory locusts in China were associated with cold spells, suggesting that China's projected climate warming could decrease the pest's numbers. The study was published in Proceedings of theNational Academy of Sciences on 17 September, 2007.  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
