2．2．2 利用ESI进行世界大学科研竞争力评价
在不少关于SCI功能方面讨论的文章，大家基本达成这样的共识：“SCI比较适合国家、机构、期刊等宏观对象的评价”。由于ESI是基于SCI和SSCI的，并且是一个国际性的数据库，利用其进行世界大学评价是可行的。武汉大学的硕士研究生熊璐在其毕业论文中，曾设置了“论文总数，论文被引频次总数，论文篇均被引频次，顶尖论文总数，顶尖论文被引频次总数，顶尖论文篇均被引频次。高被引论文总数，高被引论文被引频次总数，高被引论文篇均被引频次，热门论文总数，热门论文被引频次总数，热门论文篇均被引频次”这十二个指标并赋予不同权重进行了国内12所高校科研竞争力评价方面的积极探索。这里我们引用了她的权重、原始数据和结果，最后对她的评价结果进行了深层次的分析。其权重设置依次如下所示。 相似文献

The way retracted papers have been mentioned in post-retraction citations reflects the perception of the citing authors. The characteristics of post-retraction citations are therefore worth studying to provide insights into the prevention of the citation chain of retracted papers. In this study, full-text analysis is used to compare the distinctions of citation location and citation sentiment—attitudes and dispositions toward the cited work—between the conditions of correctly mentioning the retracted status (called CM) and not mentioning the retracted status (called NM). Statistical test is carried out to explore the effect of CM on post-retraction citations in the field of psychology. It is shown that the citation sentiment of CM is equally distributed as negative, neutral, and positive, while for NM, it is mainly distributed as the latter two. CM papers tend to cite retracted papers in Methodology, whereas NM papers cite more in Theoretical Background and Conclusion. The perception efficiency of retractions in psychology is low, where the average unaware duration (UD, the period between when the retraction note has been published and when the first citation directly pointed out its retracted status) lasts for 2.88 years. Also, UD is negatively correlated with the quantity of CM and the growth rate of NM, the proportionate change of NM before and after the first CM paper appears (P <0.01). After being aware of retractions, the average rate of change (ARC, the total change divided by its taken time) of NM declines significantly (Z=-2.823, P <0.01) whereas CM sees a raise in most disciplines, which contributes to the reduction of possible interdisciplinary impact. 相似文献

为评价H指数与影响因子、总被引频次的关系,以2009年《中国期刊引证报告》（扩刊版）中166种医学期刊的H指数、影响因子、总被引频次、引用刊数和来源文献量为源数据,采用SPSSl6．0软件作线性、对数、二次多项式、三次多项式回归拟合和Logistic回归。二维散点图和曲线回归拟合分析均发现,H指数与影响因子、总被引频次、引用刊数呈密切相关,但与来源文献量的相关性不强。因此,H指数、影响因子、总被引频次应相互补充,共同用于医学类期刊学术影响力的评价。 相似文献

At times, there are reasons for authors to make a formal statement of retraction of work they publish in biomedical journals. This study examines 235 retracted articles and looks at the reasons for these retractions and citations to the articles subsequent to retraction. The primary reasons for retraction are error of various kinds (such as problems with method or sample, including contamination of samples) and misconduct. The 235 articles are cited a total of 2,034 times after retraction. This set of citations can be divided into two groups: citations that appear in journals included in the Abridged Index Medicus and those that appear in other journals included in MEDLINE. While most of the citations in these two groups of journals can be categorized as "implicitly positive," 275 make explicitly positive mention of retracted articles. The implications for continued citation for biomedical research and clinical practice are discussed. 相似文献

Objectives:
The research identified the publication types and ages most frequently cited in the infectious diseases literature and the most commonly cited journals.Methods:
From 2008–2010, 5,056 articles in 5 infectious diseases journals cited 166,650 items. Two random samples were drawn: one (n = 1,060) from the total set of citations and one (n = 1,060) from the citations to journal articles. For each sample citation, publication type and date, age of cited item, and inclusion of uniform resource locator (URL) were collected. For each item in the cited journal articles sample, journal title, publication date, and age of the cited article were collected. Bradford zones were used for further analysis.Results:
Journal articles (91%, n = 963) made up the bulk of cited items, followed by miscellaneous items (4.6%, n = 49). Dates of publication for cited items ranged from 1933–2010 (mean = 2001, mode = 2007). Over half (50.2%, n = 483) of cited journal articles were published within the previous 5 years. The journal article citations included 358 unique journal titles.Discussion:
The citations to current and older publications in a range of disciplines, heavy citation of journals, and citation of miscellaneous and government documents revealed the depth and breadth of resources needed for the study of infectious diseases.Highlights
- Literature on infectious diseases is multidisciplinary, encompassing medical specialties, public health, and the medical sciences.
- Infectious disease publications cite journal articles more than 90% of the time. Cited journal articles greatly range in age at citation: more than a quarter were over 10 years old.
- Infectious disease citation patterns resemble clinical medicine citation patterns more than public health citation patterns.
Implications
- Infectious disease professionals need access to general medicine titles as well as infectious disease, immunology, virology, microbiology, and public health literature.
- Librarians serving infectious disease researchers and practitioners should provide access to older materials, especially journal back files, to support the cyclical needs of their patrons.

One of the flaws of the journal impact factor (IF) is that it cannot be used to compare journals from different fields or multidisciplinary journals because the IF differs significantly across research fields. This study proposes a new measure of journal performance that captures field-different citation characteristics. We view journal performance from the perspective of the efficiency of a journal's citation generation process. Together with the conventional variables used in calculating the IF, the number of articles as an input and the number of total citations as an output, we additionally consider the two field-different factors, citation density and citation dynamics, as inputs. We also separately capture the contribution of external citations and self-citations and incorporate their relative importance in measuring journal performance. To accommodate multiple inputs and outputs whose relationships are unknown, this study employs data envelopment analysis (DEA), a multi-factor productivity model for measuring the relative efficiency of decision-making units without any assumption of a production function. The resulting efficiency score, called DEA-IF, can then be used for the comparative evaluation of multidisciplinary journals’ performance. A case study example of industrial engineering journals is provided to illustrate how to measure DEA-IF and its usefulness. 相似文献

This article presents a citation analysis of articles published in 2011 from 11 kinesiology journals. The results of the citation analysis of 11 kinesiology journals are compared to a citation analysis of articles published in 2011 by faculty in the School of Kinesiology, University of Michigan. Comparing the four areas of kinesiology, Movement Science, Athletic Training, Sports Management, and Physical Education, the results show that articles published in Movement Science and Athletic Training cited a higher percentage of journal articles than articles published in Sports Management and Physical Education. While some of the materials cited went as far back as 1874, the mean age ranged from 1996 to 2004. Human Kinetics was the most cited publisher and the American Journal of Sports Medicine was the most cited journal. The University of Michigan Library owns 75% of the materials cited in the publications cited by School of Kinesiology faculty. Faculty in the School of Kinesiology cited many textbooks, a format not actively collected by the library before this analysis. 相似文献

This paper takes the cue from the case of a retracted paper, cited both by the retraction notice and by an article published later in the same journal. This led to analysis and discussion on the skewness of citations in the journal Sustainability and within Multidisciplinary Digital Publishing Institute (MDPI) journals, particularly investigating self‐citations at journal and publisher levels. I analysed articles published by Sustainability in 2015 and found that self‐citations are higher than expected under a uniform probability distribution. Self‐citations in this journal make a 36% difference to the journal's impact factor. This research raises the question of what citation patterns can be expected as normal, and where the boundary between normal and anomaly lies. I suggest the issue deserves further investigation because self‐citations have several implications, ranging from impact factors to visibility and influence of scientific journals. 相似文献

This study examines how the social sciences' debate between qualitative and quantitative methods is reflected in the citation patterns of sociology journal articles. Citation analysis revealed that quantitative articles were more likely to cite journal articles than monographs, while qualitative articles were more likely to cite monographs than journals. Quantitative articles cited other articles from their own quantitative-dominated journals but virtually excluded citations to articles from qualitative journals, while qualitative articles cited articles from the quantitative-dominated journals as well as their own qualitative-specialized journals. Discussion and conclusions include this study's implications for library collection development. 相似文献
