【目的】 总结笔者所在期刊组织专题/专刊(以下简称“重点号”)的工作模式,为高校医学学报实现规模化组稿提供参考。【方法】 比较《山东大学学报(医学版)》2016—2017年刊发的7个重点号中的约稿及同卷期自由来稿的下载频次和被引频次,分析重点号的刊出效果。回顾重点号的组织过程,总结组稿模式,归纳要点,反思不足。【结果】 重点号约稿的篇均下载频次和被引频次分别是同卷期自由来稿的2.74倍和6.00倍,基本实现预期的约稿效果。《山东大学学报(医学版)》通过两年多的实践,建立了适合自身发展的重点号组稿模式,主编和编委的办刊热情得到了有效激发,组稿达到较大规模,办刊进入良性循环。【结论】 建立的重点号组稿模式可以明显提升期刊的学术影响力,具有较强的可操作性和可复制性;高校医学学报可以通过主动建立适合自身发展的组稿模式,突破办刊困境。 相似文献

【目的】分析普通高校学报零被引论文产生的原因,为提升普通高校学报办刊质量和学术影响力提出对策建议。【方法】 采用文献计量方法,从作者群特征、学科分布、基金项目情况等对《天津职业技术师范大学学报》发表年限为6～10年的零被引论文进行统计与分析。【结果】作者群方面,零被引论文作者呈现年轻化、学术影响力偏低等特征;学科分布方面,零被引论文多来自非优势学科;项目资助方面,零被引论文获得的项目资助较少且层次较低。【结论】来稿质量难以保证、传播形式单一以及引用偏好和规范等问题,都导致普通高校学报零被引现象的产生。因此,应当通过丰富和优化稿件来源、提升稿件规范性、开辟多元化宣传推广途径、加强软硬件建设等方式,提升普通高校学报的综合实力和学术影响力,推动其良性发展。 相似文献

安徽省高校自然科学学报学术影响力综合评价分析 ——基于因子分析法 总被引：1，自引：1，他引：0
选取2012版《中国学术期刊影响因子年报(自然科学与工程技术)》中的11个文献计量指标,构建安徽省高校自然科学学报学术影响力水平评价指标体系。运用因子分析法,对安徽省高校自然科学学报的学术影响力水平进行综合评价,探究判定高校学报学术影响力水平的主要文献计量指标。结果表明:因子分析法不仅可以解决学报学术影响力综合评价中指标的相关性和权重选取问题,还可以有效消除自引过高导致的影响力评价失真问题;复合他引影响因子或复合影响因子不能作为衡量学报学术水平的唯一指标,主要指标有Web即年下载率、复合他引影响因子、复合影响因子、基金论文比、被引半衰期限、复合即年指标、可被引文献量、引用期刊数、总下载量、复合总被引,其中Web即年下载率、可被引文献量、复合他引影响因子对学报学术水平的影响权重最大。 相似文献

【目的】 对比国内高被引论文在国外的被引情况与国外高被引论文在国内的被引情况,探讨二者的相关性,以了解国内外高被引论文的差异。【方法】 选择2017年《中国科技期刊引证报告(核心版)》医药大学学报类综合评价总分排名前5位的期刊,选取2008—2017年各期刊在CNKI中的高被引论文共512篇及WoS中高被引论文共486篇,统计分析所选文献的被引频次等相关指标。【结果】 5种期刊的CNKI高被引论文的被引频次差异较小,而WoS高被引论文的被引频次差异较大;CNKI高被引论文的被引频次远高于WoS高被引论文的被引频次;除《南方医科大学学报》外,CNKI/WoS高被引论文的被引频次与其在WoS/CNKI中的被引频次的差异不具有统计学意义(P>0.05)。【结论】 我国5种国内学术影响力较高的医药大学学报的国际影响力均较低,这些期刊国内/外高被引论文的被引频次与其在国外/内的被引频次之间的相关性均不明显,国内外对5种期刊的引用存在差异。 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

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

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
