开放获取运动给科技期刊的出版模式带来变革.面对前所未有的机遇和危机,国际上的科技期刊积极回应:新兴出版商大量新办开放获取期刊;传统出版商开设OA子刊,化"危"为"机";多数期刊打造混合出版模式,实现转型过渡发展.与此同时,我国科技期刊受到严峻的挑战:科技期刊开放获取发展不成熟,加速科研论文与经费外流;没有遵循国际OA标准,无法实行OA经营;政策制度不成熟,配套设施不匹配.在此背景下,本文提出开放获取环境下我国科技期刊的发展对策:遵循国际OA出版规范,创立中国特色的期刊OA模式;发展国内英文版期刊,实行国内外APC同质同价;建立集中开放获取平台,推进期刊集约化发展;确认预印本首发权,无缝对接科技期刊的优先出版;强化OA出版质量监控,培育市场化出版生态. 相似文献

本文通过对SCIE收录的国际眼科学期刊开放获取（OA）情况和程度的研究发现：完全OA期刊随时间延长被引频次逐渐增长。完全OA、部分OA、非OA期刊文献计量学指标差异不大。与非OA论文相比,OA论文数量、百分比、总被引频次、年均被引频次稍高。OA期刊优势主要体现在被引频次的增长上,OA程度和资源利用度尚低。建议有关部门加大经费支持力度,期刊加强网站建设,提升自身影响力。 相似文献

论文处理费是OA论文的重要组成部分,长久以来,由于没有统一的收费框架和强制要求,APC费用一直处于黑箱状态,严重影响了开放获取进程.为解决此问题,以推进开放获取为目标的S联盟制订了APC标准化框架并要求出版商按照框架公布收费明细.文章对2020年5月S联盟针对OA论文制定的APC框架——《出版服务和费用明细框架》和《S计划价格和透明度框架》及执行框架的四家OA出版商的完成情况进行了研究,对比了四家出版商的APC收费明细,并对我国OA论文的APC情况进行调查,以期为我国科技期刊的规范化发展提供参考. 相似文献

S计划的提出将开放获取(Open Access, OA)提升到一个新的高度,对于中文学术期刊的OA必须深入思考。在OA2020的推进过程中,学术出版不同环节经历着长期的博弈和努力,而绝大多数中文学术期刊由于存在着主观和客观上的障碍,只在自建网站上实施了OA。为了推进高质量中文学术期刊金色OA并达到知识普惠社会发展的要求,笔者认为应该允许相关期刊收取合理的文章处理费,充分利用现有的OA平台,并探索在期刊集成平台上的OA。 相似文献

Hybrid Journals: Ensuring Systematic and Standard Discoverability of the Latest Open Access Articles
An important current challenge for research information providers is ensuring the automated discovery of Open Access (OA) content in hybrid journals. We found no evidence of discovery services that are able to systematically identify the crucially important free full-text availability of OA articles regardless of where and how such articles have been published (i.e., in fully OA journals or in hybrid journals). A solution is important because hybrid journals are proliferating and consequently the chances of missing OA articles is real and is happening. Nearly all of the major publishers now provide such journals in order to take advantage of recent changes in research funder requirements, and to be competitive in the new OA business model. By working with a group of scholarly publisher partners and by using standard metadata elements that publishers are already familiar with, we show a systematic and standardized manner to identify OA at the article level. Our proposal is to embed OA-related elements in the metadata freely exposed by publishers for aggregators and discovery services. For example, in the Table of Content (TOC) Really Simple Syndication feeds the publishers use to announce new journal issues and content. Based on the initial results obtained, we discuss the capabilities of our solution, and evaluate the impact produced by our application in the systematic discoverability of OA content from the participating hybrid journals, using an implementation done with the freely available journal current awareness service—JournalTOCs. 相似文献

The article processing charge (APC) is currently the primary method of funding professionally published open access (OA) peer‐reviewed journals. The pricing principles of 77 OA publishers publishing over 1,000 journals using APCs were studied and classified. The most commonly used pricing method is a single fixed fee, which can either be the same for all of a publisher's journals or individually determined for each journal. Fees are usually only levied for publication of accepted papers, but there are some journals that also charge submission fees. Instead of fixed prices, many publishers charge by the page or have multi‐tiered fees depending on the length of articles. The country of origin of the author can also influence the pricing, in order to facilitate publishing for authors from developing countries. 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

欧美出版社开放存取期刊论文处理费研究 总被引：1，自引：0，他引：1
论文处理费伴随着开放存取期刊的出现而进入公众视野。20世纪末,开放存取期刊由于没有成熟的商业盈利模式,国际上知名的出版社均对这种新型数字出版方式表示过疑虑。而现今,传统出版集团相继发行各自的开放存取平台,这主要得益于论文处理费的推行。本文介绍欧美各大知名出版社旗下开放存取期刊论文处理费的相关收费情况,分析论文处理费收取的完整体系,以期为国内学术期刊开放存取平台的发展提供策略建议。 相似文献

掠夺性科技期刊与科技期刊中掠夺性现象的特征研究 总被引：1，自引：0，他引：1
近年来,由于开放存取(OA)出版模式的兴起,掠夺性科技期刊的出现也引起国内外学者的关注。国内科技期刊中也存在着类似的管理和学术信誉差、商业利益至上的现象,并对正常的科研成果和出版资源形成了干扰和掠夺。本文将这些存在于国内外科技期刊中的掠夺现象一并回顾和总结,认为一方面国内科技期刊从业者,应重视和适应新兴OA期刊的发展趋势,另一方面相关科研管理部门也应逐步建立措施,完善掠夺性期刊预警制度。 相似文献

《The Journal of Academic Librarianship》2022,48(3):102418
Jeffrey Beall, a US librarian, coined the term “predatory publishing” specifically to describe a movement or phenomenon of open access (OA) journals and publishers that he and others believed displayed exploitative and unscholarly principles. Using a blog to transmit those ideas, and profiling specific cases using blacklists, one of the most polemic aspects of Beall's blog was its tendency to attract and incite academic radicalism. Beall targeted both publishers and standalone journals, but how he precisely determined that an OA journal or a publisher was predatory was in many cases an ambiguity. Beall's deficient and highly subjective criteria, as well as those blacklists' incapacity to clearly distinguish low quality OA publishers from predatory ones, may have negatively impacted the operations of several Beall-blacklisted OA journals and publishers. Freedom of speech that embraces prejudice, via Beall's blog, and the establishment of “predatory” blacklists, are enhanced discriminatory ideologies that continue to be carried downstream from Beall to and by other like-minded individuals and groups who proliferate academic divisiveness and may also be formalizing and institutionalizing a culture of discriminative philosophies by cloning Beall's blacklists and encouraging their continued use. 相似文献
