Elsevier收录期刊可开放存取情况的调查与分析 总被引：6，自引：0，他引：6
对Elsevier的25个学科期刊可开放存取情况进行了详细调查,分析了Elsevier期刊可开放存取的总体情况、各个学科期刊可开放存取的情况、各学科可开放存取期刊的站点分布.调查结果表明.Elsevier期刊可开放存取的比例很高,并且还在不断增长,对其进行充分开发利用或者利用这些调查结果与数据库商谈判,可以节省图书馆的资源购置经费.图5.表3.参考文献12. 相似文献

“全媒体”这个词不知何时被广泛地应用在不同层面的语境下,最终形成了一种语焉不详、所指不清的情形。何谓“全谋体”？“全媒体”在英文中为“omnimedia”,搜索国外的Elsevier（SDOL）数据库、EBSCO全文数据库以及Springer外文期刊,发现omnimedia只以专有名词形式出现,即一个名为MarthaStewartLivingOmnimedia（MSO）的公司。作为一个新闻传播学术语的“全媒体”并未为国外新闻传播学界所提及。 相似文献

版权问题一直是制约开放获取(OA)的瓶颈之一,为了更有效地了解和推动OA期刊版权研究,对国外期刊著作权让渡的6种模式按照从作者权利最大化到出版者权利最大化依次变化的顺序进行详细分析。选取Reed Elsevier、Thomson Reuters、Springer Science+Business Media、John Wiley&Sons、ACS世界5大科技医药期刊出版商,从其官网和SHERPA/RoMEO数据库观察它们的OA出版政策,并从期刊的声望和质量、版面费、作品使用、职业发展四方面对影响作者选择出版者的主要因素进行分析。最后,从"长尾"格局和利益相关者的较量两方面对国外期刊版权模式现状进行总结。 相似文献

Based on the 1,608 journals covered by the Chinese Science & Technology Journal Citation Reports (2005 edition), we analyzed the open access (OA) publishing situation of Chinese scientific journals. From this database we identified 91 journals offering full OA; a further 139 journals offered delayed OA. Data collected at three different time points (January 2006, July 2006, and January 2007) showed that the OA status of these journals is not stable; some OA journals subsequently became non‐OA. Most of the Chinese OA journals are not part of a larger aggregation, but are published independently. Relatively more OA journals are published in the fields of medicine and biology. Citation indicators of OA journals were found to be higher than those of non‐OA journals. 相似文献

This paper examines the characteristics of 462 open access (OA) journals being published in India under the green, gold and hybrid models. The sample of journals was selected from DOAJ, IndianJournal.com and Open J‐Gate. Journal characteristics were measured in terms of growth, subjects, publishers, and citations under each model. While characteristics such as growth, subject, and publisher have been identified by exploring the journal's website only, the citation count of these journals has been calculated by using Google Scholar and the Indian Citation Index. The gold road is now the most popular form of OA publishing in the subcontinent. There is a great variation in the size of OA journals and in their publishers. One publisher has more than 77 journals, but 264 publishers publish a single journal only. Overall, the OA journal landscape is greatly influenced by a few key publishers and journals. While 43% of journals charge publication fees and the fees vary from as low as US$10 to as high as US$400, the highest impact factor of the gold OA journals has been noted as 0.58. The data presented here suggest that publication fees are not a major barrier to authorship within the fields of computer science, pharmacy, and medicine. 相似文献

To determine the mix of resources used in social gerontology research, a citation analysis was conducted. A representative sample of citations was selected from three prominent gerontology journals and information was added to determine subject scatter and database coverage for the cited materials. Results indicate that a significant portion of gerontology research, even from a social science perspective, relies roughly equally on medical resources as it does social science resources. Furthermore, there is a small but defined core of literature constituting scholarly “territory” unique to gerontology. Analysis of database indexing indicated that broad, interdisciplinary databases provide more comprehensive coverage of the cited materials than do subject-specific databases. 相似文献

In this paper, we conduct a comparative analysis to examine the characteristics and evolutionary trends of open access (OA) publications in natural and social sciences. We use data recorded by Science Citation Index Expanded, Social Sciences Citation Index, and Journal Citation Reports during 2001–2015 as the main source. We then comparatively analyse the characteristics of natural and social sciences in terms of historical evolution, main contributors, and distribution of OA journals and publications across different languages, disciplines, and impact factor quartiles. Our results suggest that both natural and social sciences experienced dramatic growth of OA journals since 2009, but the share of social science OA journals within journal impact factor quartile 1 is much lower than that of natural sciences. While natural and social sciences share some similarities in OA publishing activities, such as main countries of contribution, they differ greatly in dimensions such as OA ratio across specific disciplines, countries, and publishing languages. We acknowledge that OA publishing offers a level playing field for traditionally disadvantaged languages, countries, and scientific disciplines, but meanwhile, the advancement of high‐quality OA publishing needs more targeted and sophisticated approaches to tackle differences in natural and social sciences. 相似文献
