如何提高英文版科技期刊的被引频次和影响因子

从总被引频次和影响因子2方面分析我国英文版科技期刊的引用指标的现状和引用指标偏低的原因.提出了提高英文版科技期刊被引频次和影响因子的措施:1)注重期刊的国内外发行工作;2)通过建立英文网站及加入国内外知名数据库,提高文章的点击率及浏览量;3)请专家把语言关.     

关于利用被引频次支付期刊论文部分稿酬的尝试

目前,国内期刊社关于论文作者稿酬的支付没有统一的标准,有的期刊社不支付稿酬,有的期刊社稿酬支付仍然沿用1999年发布的《出版文字作品报酬规定》,还有些期刊社采取优稿优酬制度,导致作者意见较多。为了更加公平合理地给期刊论文作者支付稿酬,建议国内期刊社可采用基本稿酬+被引频次支付部分稿酬的办法,并就其依据、实施方法、统计被引频次时间范围、不同期刊引用区别对待及其应用的可行性进行分析总结。     

Kazakh analogue of the science citation index (SCI) as an important parameter of scientific research activities

The purpose of the Kazakh publication citation indicator that has been developed in Kazakhstan since 2005 is to carry out scientometric analysis of scientific publications to determine their citation rate. At present, the bibliographic database (BDB) on citation includes information on the publication activities and citation index of approximately 30000 Kazakh scientists and specialists. They had over 18000 scientific papers published in over 500 domestic and foreign journals. The total quantity of references to papers by Kazakh scientists was more than 28000. The Kazakh analogue of the science citation index determination system is an efficient tool for analytical work with the BDB of scientific publications, which makes it possible to calculate publication activities and citation parameters, which are used to define the value and demand for the results of scientific work in various fields of domestic science.     

科技期刊参考文献数量与部分引证指标的定量关系初探

针对目前相关研究缺乏定量分析的现状,探讨中国科技期刊参考文献数量与总被引频次、影响因子的定量关系.根据《中国科技期刊引证报告》2000-2013年的相关统计数据,拟合出相应的关系曲线及公式,分析篇均引文数与平均总被引频次、篇均引文数与平均影响因子的关系和变化趋势.结果表明:篇均引文数与平均总被引频次呈现较好的线性关系;篇均引文数与平均影响因子呈现比较理想的三次多项式关系;拟合曲线与统计数据吻合良好.根据这2个拟合公式进行预测,当篇均引文数达到20时,中国科技核心期刊的平均总被引频次有望超过1 700,平均影响因子有望超过1.0.根据预测结果,如果篇均引文数能在现有基础上提高26％,则平均总被引频次有可能提高44％,平均影响因子有可能提高90％.

SCI收录中日韩印4国期刊引文指标的比较

以JCR 2006—2008年的数据为基础,将我国与日本、韩国、印度的各项指标作比较,结果表明我国内地被SC I收录的期刊与论文在数量和质量方面都呈快速增长态势,虽与欧美有较大差距,但在亚洲明显超过印度,部分指标超过了我国台湾与韩国,仅次于日本。这启示我们:不必妄自菲薄,认为我国期刊质量都不如国外;当然,也要看到差距,努力争取更大的国际影响。     

Subject citation bibliographies for social science material in the Caribbean

Abstract

Libraries in Latvia, as in other Eastern European countries, have begun implementing automated systems. This article outlines the state of automation in Latvian libraries and discusses the problems associated with providing subject access in their computerized catalogues. Issues relating to subject searching and retrieval in Latvian online catalogues (MARC, keyword vs controlled vocabulary search, stemming and truncation, subject headings and thesauri, retrieval mechanisms, use-system interfaces) are discussed. Recommendations are made for further progress in Latvian online catalogues in general and for subject access in particular. User education and general library concerns (classification, retrospective conversion, data exchange and networking) are also considered.     

2008-2013年中外科技期刊载文与引证指标分析

基于2008-2013年Thomson Reuters发布的Journal Citation Reports (JCR)及中国科学技术信息研究所发布的《中国科技期刊引证报告》(CJCR),比较分析中外科技期刊载文量、总被引频次、影响因子、即年指标等各主要文献计量指标的变化.结果显示,我国被SCI收录期刊的数量和影响力指标近年来总体上呈上升态势,但年平均载文量却稍有下降,以中文期刊为主的CJCR收录期刊数量和年平均载文量均呈停滞增长甚至下降的趋势.这可能表明我国科技期刊的稿源竞争力有所下降.

医学期刊评论性文章摘要的添加对期刊被引频次的影响

研究医学期刊评论性文章摘要的添加对期刊被引频次的影响。以某杂志为研究对象。该杂志2006年为评论性文章添加了中英文摘要。研究结果显示,与2005年相比,该杂志2006年所发各类文章的总体被引频次及篇均被引频次均下降,尤以论著类文章明显,评论性文章变化不大,不能明确评论性文章摘要的添加对期刊被引频次是否有影响。     

《中国水稻科学》769篇退稿的追踪调查与思考

为了自查编辑的退稿失误率,提高编辑初审退稿的准确率,兼顾编辑工作效率和期刊质量,调查了《中国水稻科学》2010—2014年间的769篇退稿在他刊的发表情况。截至2017年5月,235篇未发表,534篇退稿在125种刊物上发表,其中92篇退稿发表在影响因子高于1.0的期刊。17篇退稿出现一稿两刊。在刊出的534篇文章中,134篇被引频次为0,102篇被引频次为1,181篇被引频次为2~5,被引频次在10以上的仅有65篇。笔者认为,通过提高编辑的学术素养,增进对专业研究领域的把握,可以减少稿件误判率,做到精准退稿,同时,编辑应掌握沟通技巧,培养亲和力,保证期刊的可持续发展。     

A comparative study of cross-domain research output and citations: Research impact cubes and binary citation frequencies

Across the various scientific domains, significant differences occur with respect to research publishing formats, frequencies and citing practices, the nature and organisation of research and the number and impact of a given domain's academic journals. Consequently, differences occur in the citations and h-indices of the researchers. This paper attempts to identify cross-domain differences using quantitative and qualitative measures. The study focuses on the relationships among citations, most-cited papers and h-indices across domains and for research group sizes. The analysis is based on the research output of approximately 10,000 researchers in Slovenia, of which we focus on 6536 researchers working in 284 research group programmes in 2008–2012.As comparative measures of cross-domain research output, we propose the research impact cube (RIC) representation and the analysis of most-cited papers, highest impact factors and citation distribution graphs (Lorenz curves). The analysis of Lotka's model resulted in the proposal of a binary citation frequencies (BCF) distribution model that describes well publishing frequencies. The results may be used as a model to measure, compare and evaluate fields of science on the global, national and research community level to streamline research policies and evaluate progress over a definite time period.     

Testing the fairness of citation indicators for comparison across scientific domains: The case of fractional citation counts

Citation numbers are extensively used for assessing the quality of scientific research. The use of raw citation counts is generally misleading, especially when applied to cross-disciplinary comparisons, since the average number of citations received is strongly dependent on the scientific discipline of reference of the paper. Measuring and eliminating biases in citation patterns is crucial for a fair use of citation numbers. Several numerical indicators have been introduced with this aim, but so far a specific statistical test for estimating the fairness of these numerical indicators has not been developed. Here we present a statistical method aimed at estimating the effectiveness of numerical indicators in the suppression of citation biases. The method is simple to implement and can be easily generalized to various scenarios. As a practical example we test, in a controlled case, the fairness of fractional citation count, which has been recently proposed as a tool for cross-discipline comparison. We show that this indicator is not able to remove biases in citation patterns and performs much worse than the rescaling of citation counts with average values.

科研合作对期刊论文被引频次的影响

以图情类影响力最大的4种期刊在2000-2009年的载文量与被引频次为样本,采用符号检验与相关分析的方法,从合作模式与合作频率两个方面分析科研合作对期刊论文被引频次的影响。研究发现：①合作发表论文的影响力明显高于独立（无合作）发表的论文;②在获得被引频次方面,国际合作并不优于国内合作,高校并不优于研究所;③研究机构的合作次数与被引频次呈正线性相关关系,但机构的合作频率与篇均被引次数没有显著相关。
