We analyze the self‐citation rates of scientific and technical journals in the SCI database from China, Japan, India, and Korea from 2007 to 2009. Korea has the highest self‐citation rate, Japan the lowest. Compared with 2007, the overall level of self‐citation rate declined across all four countries in 2008. In 2009, however, the self‐citation rate of the three countries other than China rose a little. The total cited frequency and impact factor of excessive self‐citing journals and zero self‐citation journal in China, Japan, India, and Korea are all lower than those of the mean of all journals included in the SCI in 2009. It appears that the academic influence of journals whose self‐citation rates is either too low or too high is small. 相似文献

This paper compares ‘high‐impact’ papers from China, Japan, India and Korea in 2012, together with papers from these countries in Cell, Nature, and Science (CNS) from 2010 to 2012. China leads on ‘highly cited’ and ‘hot’ papers in 2012, while Japan has the highest number in CNS (653), followed by China (471), Korea (131) and India (83). Although China published more high‐impact papers in 2012, papers published in CNS were at a relatively low level, which appears to show that while some of the research in China is at a relatively high level, this is not entirely reflected in the number of papers in these ‘elite’ journals. 相似文献

This study examined the development of English-language journals indexed by the database of Journal Citation Reports (JCR) and owned by six non-English-speaking countries (China, Japan, South Korea, Taiwan, Italy, and Spain) and four countries where English is an official national language (Australia, Canada, India, and Singapore) over a 21-year period. Four types of journals were identified based on changes in journal impact factor (JIF) and rank percentage per year. The results suggest that “growth” journals with trends of increasing JIF and rank percentage outnumbered other types of journals for each country and were not concentrated in particular subject categories. Over half of the growth journals in eight countries were positioned at Q3 and Q4 levels. No significant differences in the average age of growth journals were identified between countries. Although China possessed the highest percentage of growth journals, its journals with the highest growth were at the Q4 level. This study concluded that China and South Korea should monitor their development of JCR journals due to their faster improvement in the average annual rank percentage per growth journal. One limitation is that a considerable proportion of junior English journals were not analyzed in this study. 相似文献

目的：评估中国科学引文数据库（CSCD）收录的7种儿科类期刊质量。方法：通过“中国科技期刊引证指标数据库”获得7种儿科类期刊2013年的篇均参考文献、被引半衰期、H 指数、引用半衰期、自引率、影响因子、即年指数、自被引率等数据,并将指标按其与期刊质量的正、负相关关系分为两组,分别绘制蛛网图,然后结合7种儿科类期刊的发文情况进行质量评估。结果：以篇均参考文献、影响因子、H 指数、即年指数为一组进行蛛网图法评估,排在前3位的期刊是《中华儿科杂志》《中华实用儿科临床杂志》、《中国循证儿科杂志》;以引用半衰期、自引率、被引半衰期、自被引率为一组进行蛛网图法评估,排在前3位的期刊是《中国循证儿科杂志》、《中华儿科杂志》、《临床儿科杂志》。结论：7种儿科类期刊整体质量较高,《中国循证儿科杂志》、《中华儿科杂志》综合评价最好,其他各刊还有提升空间。 相似文献

Thirty‐six ophthalmology journals indexed by the Science Citation Index (SCI) in 2003 were selected to study the role of the ‘papers cited rate’ in scientific journal evaluation. The 2‐year, 3‐year, 5‐year, 8‐year, and 10‐year cited rates of these papers were calculated to analyze statistically the correlations with impact factor, 5‐year impact factor, immediacy index, eigenfactor score, article influence score, and total cites. The results of questionnaires sent to 8,525 ophthalmologists were used to analyse the correlations between the papers cited rates for different years and traditional bibliometric indicators. The results showed that eigenfactor score and total cites were better than other indicators, and impact factor was better than the 5‐year impact factor. The 2‐year and 3‐year cited rates of papers were reasonable for evaluating science journals, and the 2‐year cited rate was better than the 3‐year cited rate. The 5‐year (and more than 5 years) cited rates were not significant in evaluating science journals. 相似文献

国内外生物医学期刊稿件中医学伦理学意识比较 总被引：12，自引：1，他引：11
为了了解近年来我国与西方国家生物医学期刊在医学伦理学方面的意识是否有改善,选取2004和2005年出版的12种国外影响因子大于3的SCI收录期刊与11种中国科学引文数据库(CSCD)核心库收录期刊中刊登的论著进行比较.结果显示,国外医学期刊无论在获得伦理委员会批准还是受试者知情同意方面均好于国内医学期刊,而国内一些医学期刊几乎无医学伦理学意识.认为我国医学期刊应从提高编辑人员素质,重视医学伦理学的宣传教育,不同的稿件应区别对待,完善稿件中的知情同意以及其他医学伦理学问题等几个方面入手,积极改善缺乏医学伦理学意识的现状. 相似文献

2008-2013年中外科技期刊载文与引证指标分析 总被引：1，自引：0，他引：1
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. 相似文献

Countries in East Asia – specifically China, Japan, and South Korea – are rapidly emerging as major contributors to global research output. However, owing to barriers in language and culture, it is possible that authors from these countries face unique challenges in getting published. Moreover, as submissions from these countries increase, journal editors may be able to spot some trends in the problems encountered when processing these submissions. This study presents the results of two surveys – one involving non‐native English‐speaking authors from East Asia and another involving international journal editors. The surveys were designed to throw light on the challenges East Asian authors face in the publication process and the perceptions journal editors have of submissions from East Asian countries. Here, we present and discuss the survey results, highlight gaps in the perspectives of authors and journal editors, and make recommendations to bridge these gaps. 相似文献

为提升预防医学与公共卫生学综合类中国科技核心期刊学术质量和学术影响力,通过2013—2019年出版的《中国科技期刊引证报告（核心版）》收集总被引频次、影响因子、即年指标、他引率、AR论文量、平均引文数、平均作者数、基金论文比等资料,采用线性混合模型分析2012—2018年各个指标年份间差异及变化趋势,并对总被引频次和影响因子进行排序。结果显示,2012—2018年,预防医学与公共卫生学综合类中国科技核心期刊由16种增加至22种,均为中文期刊,连续收录16种。影响因子、即年指标、AR论文量、平均引文数和平均作者数2012—2018年均呈上升趋势（P < 0.05）,总被引频次、他引率和基金论文比无明显变化趋势（P>0.05）;预防医学与公共卫生学综合类中国科技核心期刊学术质量和学术影响力不断提升。 相似文献

We investigated the self‐citation rates of 884 Chinese biomedical journals, including 185 general medicine journals, 96 preventive medicine journals, 103 Chinese traditional medicine journals, 66 basic medicine journals, 370 clinical medicine journals, and 64 pharmaceutical journals. The average self‐citation rates of these journals for the years 2005–2007 were 0.113 ± 0.124, 0.099 ± 0.098 and 0.092 ± 0.089, respectively, i.e. a downward trend year by year. The upper limits of normal values of self‐citation rates for the same period were 0.316, 0.260 and 0.238, respectively. A significant difference was found in self‐citation rate between biomedical journals of different subjects. 52 Chinese biomedical journals had no self‐citation in 2007. The total citation frequency and impact factor of these 52 biomedical journals were 263 and 0.206, respectively, which were very much lower than the average levels of all Chinese biomedical journals in 2007. A self‐citation rate higher than the upper limit was considered as excessive self‐citation: 62 (7.01%), 68 (7.69%) and 66 (7.47%) biomedical journals showed excessive self‐citation in the years 2005–2007, respectively. However, a certain amount of self‐citation is reasonable and necessary. 相似文献

以SJR为数据来源,比较分析了1996-2008年巴西、印度、中国、韩国4个国家发表科技论文数量、可引用文献量、文献被引量、自引量、篇均被引量、去除自引后的篇均被引量、H指数、文献引用率、国际合作量等9个指标。中国发表论文数最多,2003年后每年增加约3万篇。巴西、韩国文献引用率、篇均引用量高,且自引率低;印度居中等水平;中国文献引用率、篇均引用率低且自引率高;国际合作度巴西最高、中国最低。可见中国的科技论文质量与其他3个国家相比,还有一定的差距。 相似文献

在国际著名的摘要和引文数据库Scopus中检索2015-2017年医学领域国际期刊的撤稿声明,收集并分析撤稿声明中的相关信息.检索后共获得1 015篇针对已发表正式论文的撤稿声明,声明数量逐年减少.发表撤稿声明较多的期刊,普遍质量不高,撤稿数量和期刊影响因子并没有明显的相关性.从Scopus上可以获得能提供有效撤稿相关信息的声明摘要共409篇,涉及文章419篇,学术不端是撤稿的主要原因,占所有撤稿原因的46.8％.撤稿文章来自38个国家,其中数量最多的为中国(97篇)、美国(95篇)、伊朗(53篇)、日本(28篇)、印度(22篇)、英国(14篇)、韩国(11篇).几乎所有国家的撤稿原因中都包括学术不端或重复发表.撤稿声明时滞为0～26年,中位数2年,平均值3.3年.学术不端的撤稿时滞中位数为3年,重复发表的撤稿时滞中位数为1年. 相似文献

中国科技期刊国际影响力提升计划已经实施4 年.本研究拟对首批资助期刊的实施效果——国际影响力的提升做一比较分析.将2017 年JCR 收录期刊列表中所有的中国出版的 SCI 期刊分为提升计划首批资助期刊与未获资助期刊2 组,收集 2 组期刊2013—2017 年间被引频次与影响因子数据,并进行比较分析.结果发现,在首批获资助的SCI 期刊与未获资助的SCI期刊中,部分期刊的被引频次与影响因子2 个指标不升反降,部分下降幅度超过10％; 首批资助期刊仅被引频次增长率高于未获资助期刊,其影响因子的增长率反而低于未获资助期刊,提示提升计划对资助期刊国际影响力的作用尚不明显.建议6 部委调整有关资助方向和经费使用指导方向与实施细则. 相似文献
