引文归一化指标RCR与FWCI指标、F1000评分的相关性研究

【目的】 检验引文归一化指标RCR与Scopus的FWCI指标及同行评议指标F1000之间的相关性,为引文归一化学科影响力评价实践提供理论支撑。【方法】 选取国际干细胞研究领域的学术论文为研究样本,采用正态性检验及相关性分析法研究论文的RCR指标、FWCI指标及F1000推荐次数、F1000评分之间的相关关系。【结果】 RCR指标与FWCI指标具有较强的相关性,而RCR指标与F1000推荐次数和F1000评分之间仅低度相关。【结论】 作为学科归一化指标,RCR与FWCI指标在论文影响力评价上具有一致性,但与同行评议指标F1000相关性较弱。未来,RCR指标在我国交叉学科期刊评价、建立我国科技期刊影响力评价基准、构建我国科技期刊动态评价系统方面具有较大借鉴意义。     

Top 100. Revisión de los artículos más citados sobre cirugía laparoscópica del páncreas

IntroductionThe number of citations is considered as an indirect indicator of the merit of an article, journal or researcher, although it is not an infallible method to determine scientific quality. Our goal is to determine the characteristics of the articles most cited about pancreas and laparoscopy.MethodsWe performed a search of all articles published in any journal about pancreas and laparoscopy until September 2019 and selected the 100 most cited papers. We recorded number of citations, journal, year of publication, quartil, impact factor, institution, country, authors type of paper, type of surgery, topic and area.ResultsThe top 100 citations account 10,970 citations in total. The journal with the most articles is Surgical Endoscopy and 2007 is the year with the highest number of articles in the top 100 citations. The percentage of publications from America and Europe are similar.Case series is the most frequently paper, outcomes/morbidity is the most frequently discussed topic, and distal pancreatectomy is the most frequently type of surgery.ConclusionsThis bibliometric study on pancreas and laparoscopy is conditioned by the time factor, since laparoscopy has arrived later at pancreatic surgery, probably due to the morbidity and mortality associated with pancreatic surgery and the need for a high specialization in this field. The literature is recent and scarce. More and better-quality studies are needed in this field.

Most cited papers in Toxicon.

Citation of a published work is one of the parameters considered in the analysis of relevance and importance of scientific contributions. In 2002, for the first time the Impact Factor of Toxicon has risen above 2.0, placing it at the 17th position among 76 journals in the 'toxicology' field. The aim of this article was to identify the most cited articles in Toxicon, that have contributed to the steady increase of its Impact Factor. The number of citations, complete reference and type of all documents appearing in Toxicon in the period 1963-2003 were retrieved from the ISI Web-of-Science homepage. The documents retrieved were sorted by the number of citations received. A 'citation index', defined as the number of citations divided by the number of years since publication, was calculated for each document. It was clearly seen that reviews in Toxicon received 4.4-fold more citations than articles. Unexpectedly, it was found that recent papers were proportionally more cited than old ones. A decrease in the proportion of papers dealing on 'snake*' through out the period and the broadened range of subjects of the most cited papers recently published in Toxicon reflects an increased 'visibility' in other fields of toxinology. Research on plant toxins gained its own space in Toxicon with newer publications showing high citation indexes. It can be postulated that these facts helped to increase Toxicon's Impact Factor from 1.248 in 1999 to 2.003 in 2002. With the increased number of issues in Toxicon as well as publications of subject-dedicated volumes containing mostly reviews, the Impact Factor of Toxicon is expected to keep rising in the near future.     

Citation patterns and trends of systematic reviews about mindfulness

ObjectivesWe performed a citation analysis of the literature about mindfulness aimed at describing the most significant topics and the impact of more relevant papers.MethodsWe classified 128 systematic reviews about mindfulness-based intervention retrieved in Scopus according to their object, the population included and the type of mindfulness proposed. The citation counting was reported. The cumulative citation numbers per chronological years and article life were analyzed thorough a linear regression model.Results1) We observed a general increase in the number of reviews published from 2003 to 2016; 2) two reviews collected the 33% of the overall citations; 3) citation counting for clinical and mixed population collected the 90% of total citations; 4) clinical reviews had higher cumulative citation per publication/year growth.ConclusionsAs mindfulness research advances, higher attention should be given to the mechanisms by which mindfulness interventions work so as to provide fruitful insights for future research.     

基于OA及免费全文链接的期刊影响力指数优势

【目的】 为开放获取政策的制定提供理论参考,给学术搜索引擎免费全文链接的建设提供依据。【方法】 对图书馆、情报与文献学领域的26种中文社会科学引文索引来源期刊的开放获取状况与免费全文链接情况进行调查。根据期刊的开放获取状态和免费全文链接获得程度将期刊分为4类,分别在不同的时间视窗下比较4类期刊的各项评价指标的变化趋势,并进行相关性分析。【结果】 所选的26种期刊的开放获取程度为61.5%,这些期刊在百度学术中平均每篇论文拥有2.17个免费全文链接。开放获取和有高免费全文链接获得程度的期刊在不同时间视窗影响力指数下的表现都较占优势。【结论】 期刊开放获取和有较多的免费全文链接有助于期刊的被引用和影响力的提升。
