入选PubMed数据库对提升医学期刊国际影响力的作用 总被引：1，自引：1，他引：0
[目的]探讨入选PubMed数据库对提升我国医学期刊国际影响力的作用,分析加快医学期刊国际化的途径和策略。[方法]采用文献资料法、文献计量法,以2011版《中文核心期刊要目总览》中6种入选PubMed数据库和6种未入选PubMed数据库的综合性医药卫生类核心期刊为研究对象,以《中国科技期刊引证报告(核心版)》和SCI数据库为数据来源,利用SPSS20.0分别对期刊的国内被引频次、影响因子和期刊在SCI数据库的被引频次做两独立样本的非参数检验。[结果]入选PubMed的期刊在SCI数据库中的被引频次显著高于未入选PubMed的期刊(P<0.05),而两组期刊的国内被引频次和影响因子均无统计学差异(P>0.05)。[结论]入选PubMed数据库对提升医学期刊国际影响力具有重要作用。加快医学期刊的国际化除加入SCI外还可考虑加入PubMed数据库等。 相似文献

【目的】分析国际上主要的生物医学数据库收录中国生物医学期刊的现状和收录要点,旨在为国内其他医学期刊申请国际数据库收录及提升期刊国际影响力提供参考。【方法】统计并分析国际数据库(Scopus、Embase、DOAJ、MEDLINE、PMC和WoS等)收录中国医学类科技期刊的现状,深入分析收录要点,以《中国癌症杂志》申请国际数据库收录的具体工作为例,总结申请国际数据库存在的问题,并提出解决方案。【结果】各数据库收录中国生物医学期刊的情况各不相同,总体上,收录中国期刊数量有限。近年来,Scopus、DOAJ和PMC数据库发展较快,中、英文期刊均有收录;SCIE主要收录英文期刊,ESCI已加快中文期刊的收录工作,MEDLINE和PMC的收录标准则越来越高。提高期刊的内容质量是期刊的重要工作。此外,期刊应加强中英双语网站建设,建立并落实各项制度,提倡期刊采取论文英文长摘要的写作策略,进而提高期刊的展示度。【结论】近年来,中国生物医学期刊被国际数据库收录数量整体上持续增长,但仍有待提升。中国生物医学期刊被国际数据库收录不仅有助于促进期刊的制度建设及国际一流期刊的网站建设,还有助于提升期刊的内容质量... 相似文献

【目的】 比较研究“中国科技期刊国际影响力提升计划”(以下简称“影响力提升计划”)对其第一批资助的SCI收录期刊国际影响力水平的提升效果。【方法】 依据Web of Science《期刊引证报告》和中国知网《中国学术期刊国际引证报告》2013年和2016年数据,对2013年11月被“影响力提升计划”资助的非新创办的SCI收录期刊和未受资助的SCI收录期刊进行对照研究。比较其总被引频次(Total Cites,TC)、影响因子(Impact Factor,IF)、国际影响力指数(Clout Index,CI)、平均期刊影响因子百分位(Average Journal Impact Factor Percentile,AJIFP)的变化及分区提升率。【结果】 受资助期刊和未受资助期刊TC、IF、篇均被引频次、即年指标、标准化特征因子、CI、国际他引TC和国际他引IF均显著提升(P<0.05),且受资助期刊被资助后AJIFP同样提升显著(P<0.05)。除即年指标和标准化特征因子的增幅在2组间差异无统计学意义外,受资助期刊上述指标的增幅及分区提升率均显著高于未受资助期刊(P<0.05)。不同资助额度的受资助期刊间影响力指标的提升差异无统计学意义(P>0.05)。受资助期刊在资助前后可被引文献数增加并不显著(P>0.05),降低幅度超过10%的期刊共6种(14.6%)。但未受资助期刊可被引文献量降低幅度超过10%的期刊占35.8%。【结论】 “影响力提升计划”1期资助效果显著。大部分受资助期刊影响力指标提升显著,但个别期刊影响力指标不升反降。受资助期刊的可被引文献量增加并不明显,有些期刊可被引文献量下降明显。不同资助额度对期刊影响力指标的提升影响不明显。 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

Long-standing conflict between domain name registrants and trademark holders prompted the Internet Corporation for Assigned Names and Numbers (ICANN) to create a global, mandatory arbitration procedure known as the Uniform Dispute Resolution Policy (UDRP). The UDRP has been used in 2166 cases involving 3938 domain names as of 1 November 2000. The policy gives the initiator of a complaint, generally a trademark holder, the right to choose which ICANN-accredited dispute resolution service provider (RSP) will handle the case. During the preparation of the UDRP,some feared that complainant selection would lead to "forum shopping" that might bias the results. This article performs a statistical assessment of the forum-shopping thesis and finds support for it. There are statistically significant differences in the various RSPs' propensity to take away names from defendants; there are also major differences in the number of cases brought to each RSP. RSPs who take away names have the larger share of cases. The study examines other variables that might explain differences in market share, such as price, the plaintiff's nationality, or the time taken to decide a case. It finds that nationality and time also are correlated with market share. The study concludes that shopping for a favorable outcome is an important factor in the UDRP. 相似文献

<正>In Xishuangbanna,one of China’s most biodiverse regions,landscape has changed dramatically during the past three decades due to the conversion of tropical rainforest to rubber plantations.In steep areas,terraces are often constructed before planting rubber trees,which causes two important changes in the soil:the destabilization of soil in the bench terraces and the increased vulnerability of unvegetated riser faces to erosion.Few studies have documented the nature and intensity of erosion on bench terraces.Prof.LIU Wenjie and his colleagues from the Xishuangbanna Tropical Botanical Garden(XTBG)conducted a study in Menglun County(21°5′39″N,101°15′55″E),Xishuangbanna to evaluate the influence 相似文献
