【目的】 以神经病学与精神病学类核心期刊为例,探讨科技期刊媒体融合出版现状与数字版权保护情况,并提出相应建议。【方法】 以入选《中国学术期刊影响因子年报(2017年)》的29种神经病学与精神病学类核心期刊为研究对象,对其网络数据库、官方网站、微信公众号及手机客户端出版的现状和数字版权保护情况进行调查与分析。【结果】 29种样本期刊均被数据库收录出版。26种(89.7%)期刊建立了官方网站,但提供全文开放获取的期刊仅6种,占20.7%。15种(51.7%)期刊开通了微信公众号,其中3种(10.3%)期刊提供全文开放获取。手机App收录了27~29种期刊,其中超星数据库收录的15种期刊提供开放获取。网络数据库、官方网站、微信公众号及手机App提供的下载文件均未进行数字加密,数字版权保护意识薄弱。同时网络平台建设还存在缺乏个性化服务、互动性较差、同质化现象严重及表现形式单一的问题。【结论】 科技期刊媒体融合出版已较为普及,但在加强数字版权保护、打造具有期刊特色的网络平台、完善开放获取、集约化发展方面还有很长的路要走。 相似文献

【目的】分析开放获取论文是否具有引用优势,为我国开放获取出版发展提供参考。【方法】以开放获取发展相对完善的生物医学工程学科期刊为研究对象,取Web of Science核心合集数据库中工程-生物医学类目下的混合型期刊,比较不同期刊中开放获取论文的引用贡献率。【结果】工程-生物医学混合期刊中,开放获取论文的平均被引频次低于订阅论文,随着开放获取论文和期刊发文数量的增加,开放获取论文的贡献率降低,开放获取论文的贡献率与期刊引用指标间并没有确定的规律。在中等水平期刊中,开放获取论文的贡献率略高于订阅论文;而在低水平和高水平期刊中,开放获取论文的贡献率均低于订阅论文。【结论】工程-生物医学学科的混合期刊中的开放获取论文整体不具有引用优势,但对部分中等学术水平的期刊来说有一定的正面影响,中等水平订阅期刊可以适度考虑转型为混合期刊。 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

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

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
