Citation analysis provides valuable information on researchers' information use behavior, and helps librarians make evidence-based collection development decisions. However, no citation analysis of faculty publications in the field of communication has been performed to study communication researchers' information use behavior. This study examined communication faculty publication from 2006 to 2014, analyzing format, age, most frequently cited journals, and their subject areas. Analysis of local holdings provides evidence for the library's role in support of faculty research, and helps librarians articulate the value of libraries. 相似文献

学术期刊零被引现象的实证研究——以图书情报学期刊为例 总被引：1，自引：0，他引：1
[目的/意义] 利用期刊零被引率对国内图书情报学期刊的零被引现状进行定量分析,并探究论文零被引的一些原因。[方法/过程] 在参考前人研究成果的基础上,提出期刊零被引的计算方法,利用中国引文数据库和中文社会科学引文数据库的数据计算国内14种图书情报学期刊的零被引率。[结果/结论] 研究发现:①14种期刊的零被引率整体较低,反映出这些期刊上的论文大部分被研究人员所引用;②根据13种期刊零被引率分布状况,可以将其分为"锯齿型"、"W型"、"下滑型"3种类型。③论文零被引的主要原因是选题太偏和有些研究主题不属于图书情报学领域。虽然研究了国内部分图书情报学期刊零被引情况,但研究方法和一些研究结论对于其他学科期刊的零被引研究有一定借鉴意义,同时对期刊评价等方面的研究也有一定的参考价值。 相似文献

ABSTRACT This article discusses the benefit of library instruction to increase critical thinking skills among business students in the form of a vocabulary skill-building workshop. This learning opportunity represents collaboration between business librarian and classroom faculty to improve students' ability to articulate a research problem and identify information needs in order to proficiently analyze business information and make sound business decisions. Business schools increasingly rely upon standards set forth by the Association for the Advancement of Collegiate Schools of Business (AACSB) to formulate curricula and embed learning outcomes to prepare students to meet workplace expectations. These standards were utilized during workshop planning stages to implement critical thinking learning outcomes into the educational experience. Workshop curricula also relied heavily on the Guidelines for Information Competency set forth by the Association of College and Research Libraries (ACRL) to emphasize specific learning outcomes more commonly associated with the teaching of library instruction. 相似文献

Using data from Web of Science, this research investigates how physical science researchers funded by the Canadian Institutes of Health Research complied with its open access policy, and compares the citation counts of articles published through gold and green models.It was found that, for articles published between 2008 and 2015, 9% were available through gold open access routes and 13% were available through green routes; most were not openly accessible. Citation rates were comparable for green open access and non-open access articles, but citation rates for gold open access articles were lower. After controlling for publication year, citation rates of gold, green, and non-open access articles were comparable. Among gold open access articles, citation rates were highest for open access journals with article processing charges, but after controlling for publication year, articles published in hybrid journals, followed by those in open access journals with article processing charges, achieved the highest citation rates. Articles published in free open access journals had the lowest citation rates. The results suggest that green open access is the most economical approach to comply with open access policies, and that it provides researchers with at least as much research impact as gold open access. 相似文献

The Emerging Sources Citation Index (ESCI) was created recently, in 2015, but few assessments of its journal coverage have been made. The present study tries to fill that gap by comparing its coverage with that of other international abstracting and indexing (A&I) databases. Using this measure, it is feasible to benchmark this index against the other citation indexes for acceptance criteria. We analysed 6,296 ESCI‐indexed journals, 8,889 Science Citation Index Expanded (SCIE), 3,258 Social Science Citation Index (SSCI), 1,784 Arts and Humanities Citation Index (AHCI), and 22,749 Scopus journals as indexed in July 2017 to determine their inclusion in 105 databases. We found that 19.3% of the ESCI journals are not covered by any other A&I databases, a high figure compared with only 0.5% SCIE, 0.3% SSCI, 0.3% AHCI, and 5.5% Scopus journals. This low coverage suggests that the selection criteria for ESCI journals are not consistent with the overall trend in the other classical citation indexes. 相似文献

Citation based approaches, such as the impact factor and h-index, have been used to measure the influence or impact of journals for journal rankings. A survey of the related literature for different disciplines shows that the level of correlation between these citation based approaches is domain dependent. We analyze the correlation between the impact factors and h-indices of the top ranked computer science journals for five different subjects. Our results show that the correlation between these citation based approaches is very low. Since using a different approach can result in different journal rankings, we further combine the different results and then re-rank the journals using a combination method. These new ranking results can be used as a reference for researchers to choose their publication outlets. 相似文献

The purpose of this study was to identify objectively a hierarchical ranking of journals for health sciences librarians with faculty status. Such a guideline can indicate a journal's value for promotion and tenure consideration. Lists of recent research articles (1982-1986) in health sciences librarianship, and articles written by health sciences librarians, were compiled by searching Social SCISEARCH and MEDLINE. The journals publishing those articles are presented. Results show BMLA as the most prominent journal in the field. Therefore, citations from articles in BMLA from 1982 to 1986 were chosen as a sample for citation analysis. Citation analysis was employed to identify the most frequently cited journals. Some characteristics of the citations in BMLA are also discussed. The ranking of journals based on citation frequency, as a result, was identified. 相似文献

An analysis of 393 papers published by Indian social scientists and included in Social Science Citation Index (SSCI) indicates that most of these papers are published in Indian journals. Some of the papers are directly related to problems faced by Indian society. A major share of the papers are in low impact journals and have a low citation rate. Anthropology, psychology and psychiatry are the strong areas in social science research in India. 相似文献

Citation averages, and Impact Factors (IFs) in particular, are sensitive to sample size. Here, we apply the Central Limit Theorem to IFs to understand their scale-dependent behavior. For a journal of n randomly selected papers from a population of all papers, we expect from the Theorem that its IF fluctuates around the population average μ, and spans a range of values proportional to , where σ2 is the variance of the population's citation distribution. The dependence has profound implications for IF rankings: The larger a journal, the narrower the range around μ where its IF lies. IF rankings therefore allocate an unfair advantage to smaller journals in the high IF ranks, and to larger journals in the low IF ranks. As a result, we expect a scale-dependent stratification of journals in IF rankings, whereby small journals occupy the top, middle, and bottom ranks; mid-sized journals occupy the middle ranks; and very large journals have IFs that asymptotically approach μ. We obtain qualitative and quantitative confirmation of these predictions by analyzing (i) the complete set of 166,498 IF & journal-size data pairs in the 1997–2016 Journal Citation Reports of Clarivate Analytics, (ii) the top-cited portion of 276,000 physics papers published in 2014–2015, and (iii) the citation distributions of an arbitrarily sampled list of physics journals. We conclude that the Central Limit Theorem is a good predictor of the IF range of actual journals, while sustained deviations from its predictions are a mark of true, non-random, citation impact. IF rankings are thus misleading unless one compares like-sized journals or adjusts for these effects. We propose the Φ index, a rescaled IF that accounts for size effects, and which can be readily generalized to account also for different citation practices across research fields. Our methodology applies to other citation averages that are used to compare research fields, university departments or countries in various types of rankings. 相似文献

利用Google的PageRank原理进行期刊引文分析,提出期刊在引文网络中的影响力测度指标--引文网络影响力序位(Journal Impact Rank in Citation Net,Impact Rank或IR).通过对118种生物学领域的期刊进行期刊引文网络影响力测度,并将IR结果与JCR提供的影响因子(Impact Factor, IF)值进行统计学分析以考察二者的相关性和差异性.结果表明,IR值与IF值的相关性较弱,其差异性具有统计学意义.分析其原因,IR考虑了引证期刊的权重和期刊间的相互影响,更适于反映期刊在其相关学科或领域的引文网络中的相对影响力;IF值因其实质上是期刊论文篇均被引频次,其计算不考虑期刊之间的相互联系和引证期刊的权威性,因而更适用于期刊自身的纵向评价;IR与IF从两种不同角度评价期刊影响力,可互为补充. 相似文献
