【目的】比较学术论文的第一作者和合著者的生产力、影响力与论文发表后被引频次的相关性差异,为期刊编辑初审筛选高被引论文提供一定的参考。【方法】以《编辑学报》和《中国科技期刊研究》2017年发表的484篇论文为研究对象,其中独著论文142篇,合著论文342篇。利用中国知网分别收集所有论文的被引频次,并以论文所有作者2014―2020年的发文量表征作者生产力,以论文作者该时段的h指数表征作者影响力,对484篇论文的第一作者和合著者的生产力、影响力与论文的被引频次的相关性进行统计分析。【结果】独著论文的被引频次与作者生产力无关（r=0.163,P=0.053）,与作者影响力呈正相关（r=0.287,P<0.001）。在合著论文中,论文的被引频次与第一作者生产力、影响力均呈正相关（r=0.195,P<0.001;r=0.320,P<0.001）,与合著者的生产力、影响力也均呈正相关关系（r=0.115,P<0.001;r=0.134,P<0.001）。【结论】无论是独著论文还是合著论文,第一作者和合著者h指数高的论文发表后被引频次高。若合著者发文量较高,论文发表后被... 相似文献

学术期刊对科研成果的评价机制研究 总被引：6，自引：0，他引：6
在学术期刊上公开发表的科研论文是科研成果的主要表现形式之一,学术期刊作为科研成果发表的媒介,其科研评价功能是明确的,主要体现在论文发表前的评审过程和论文发表后的反响情况.利用期刊的各种计量指标评价科研成果适应了科研管理科学化、制度化、有效化的时代要求.通过分析核心期刊科研评价的利弊,提出采用综合评价、明确期刊与论文间的关系、区别3种不同层次的评价对象、借鉴分级管理办法、进行校内优秀论文评审、推行论文代表作制、区别评价教学和科研人员的学术成绩,考虑科研成果评价的多面性等8个方面改进学术期刊科研评价机制的措施. 相似文献

张垒 《中国科技期刊研究》2015,26(8):880-885
【目的】分析高被引论文的特征因素及测度其对影响因子的贡献度。【方法】以CSSCI数据库中新闻学与传播学领域高被引论文为研究对象,基于文献内容和外部特征,界定论文被引响应时间、研究内容新颖性和研究主题内容等七个影响论文高被引的特征因素。【结果】 60%以上的高被引论文作者具有较高影响力,高被引论文的平均响应时间不到一年,70%以上的高被引论文研究内容不具有新颖性,TOP 5%高被引论文对影响因子的贡献平均为27.12%。【结论】虽然参考文献数量与论文高被引不具有显著关联性,但高被引论文倾向于引用影响力较高的期刊,而且高被引论文对影响因子的贡献度较大。 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

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

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
