【目的】 分析中文科技期刊争鸣论文发表现状,探讨促进学术争鸣的途径。【方法】 以中国知网为检索平台,通过对2007—2016年农业科技类中文核心期刊群的统计分析,建立争鸣论文数量估算模型,模型通过验证后,用于估算其他自然学科期刊群争鸣论文数量,分析近10年来自然科技中文核心期刊争鸣论文发表及被引情况,并将农业科技期刊争鸣论文的发表情况与同期相应的国外期刊进行对比。【结果】 自然科技中文核心期刊争鸣论文占同期发表论文的0.012%~0.037%,占比由高到低排序为基础科学、医药卫生科技、工程科技、农业科技,其中农业科技类占比仅为0.012%,低于同期国外农业科技期刊的0.055%。对比分析争鸣论文与一般研究论文的影响发现,涉及重要热点科学问题的争鸣论文被引频次较高,影响力较大。【结论】 提出定量研究的方法模型,为其他海量文献统计提供了方法参考;我国自然科技中文核心期刊争鸣论文数量较少,学术争鸣气氛不够活跃,原因包括中庸的学术作风、趋同跟风的研究众多、视学术争鸣为人身攻击等认识误区;科技期刊可通过发表针对具有争鸣价值话题的评论性论文、鼓励读者参与对已发表论文的争鸣、刊发虽存在不完善之处但有着创新价值的研究成果等措施来引导学术争鸣的开展,从而推动科技创新和进步。 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

【目的】基于撤稿观察数据库并结合Web of Science(WoS)数据库,探讨不同学科、不同影响力期刊、不同撤销时滞的撤销原因差异,为国内学者、科技期刊、科研管理部门积极应对论文撤销和学术不端问题提供参考。【方法】通过撤稿观察数据库,逐项检索统计2016—2020年国际期刊撤销中国学者论文的原因,论文发表时间、撤销时间、所属学科,撤销论文所在期刊等数据。通过WoS数据库,检索撤销论文所在期刊的JCR分区,比较分析不同学科、不同影响力期刊、不同撤销时滞的撤销原因差异。【结果】国际期刊撤销我国学者论文的原因较为复杂,学术不端行为是主要撤销原因,重复/剽窃问题最为常见。学术不端行为的主要表现形式为文章重复、数据重复、图片重复等。不同学科、不同影响力期刊、不同撤销时滞在总体撤销原因及一级、二级学术不端行为分布等方面均具有显著统计学差异。【结论】国际期刊撤销我国学者论文的原因呈现不同特征。建议结合相关特征,持续重视撤销原因多样性和复杂性,加大对学术不端行为的打击力度,重点防范重复/剽窃问题,建立健全相关论文撤销制度体系。 相似文献

复合开放获取期刊中开放获取论文学术影响力研究 总被引：1，自引：1，他引：0
【目的】探究OA模式是否能给文献带来更高的学术影响力。【方法】 本文引入双胞胎采样法,以Sciencedirect数据库中较高OA论文占比的14种复合OA期刊为研究对象,通过文献学术影响力的分析指标和不同的时间窗口,对OA论文和非OA论文的学术影响力进行对比研究。【结果】 在论文提前出版或者出版当年,OA论文获得比非OA论文更多的被引频次,但在出版后第二年及之后,OA论文在平均被引频次、高被引论文占比等方面的表现与非OA论文的差值渐渐缩小。【结论】 研究表明：（1）OA模式能够给论文带来的学术影响力上的提升在论文出版后的早期确实存在。（2）随着出版后时间的增加,OA论文在学术影响力上的优异表现逐渐弱化,OA论文和非OA论文学术影响力慢慢趋同。 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

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
