This study, conducted at the Indiana University School of Dentistry Library using citation analysis, examined graduate dental student theses citations to determine the nature of materials cited, journal ownership, journal citation frequency, and citation age distribution. The results were compared to other scientific discipline citation analyses. Study results indicated that for the period studied, masters dental students, like medical and science students, cited recently published scholarly dental journal literature. The majority of the journals cited were owned by Indiana University system libraries. Areas for further research include faculty resource usage, e-journal impact, and interdisciplinary resource use.  相似文献

Publications of the faculty of the University of Mississippi's School of Business were examined for a citation analysis. The following data were collected: journals cited, which publishers’ journals were cited, age of the citations, and the Library of Congress classification range cited. The results were analyzed by the business school as a whole and by the four major departments in the college: Finance, Management, Management Information Systems/Production Operations Management, and Marketing. The study was undertaken to gain a better understanding of the local faculty researchers’ needs, to examine how the library supports their needs, and to compare the local results with the metaresearch focused on specific subject or journal.  相似文献

期刊学术影响力、期刊对稿件的录用标准和期刊载文的学术影响力三者之间存在同向加强的机制,来自较高影响力期刊的引用具有较高的评价意义。作者的择刊引用和择刊发表使得较低学术影响力的期刊较少被较高影响力期刊引用。因而,可以通过同时考察构成期刊引证形象的施引期刊的学术影响力及其施引频次来评价被引期刊的学术影响力。以综合性期刊Nature和Science 2010年的引证形象为例,将期刊影响因子作为学术影响力的初评结果,提出了以施引频次对施引期刊影响因子加权的计算方法,以期通过量化的引证形象实现对期刊的评价。  相似文献

Do academic journals favor authors who share their institutional affiliation? To answer this question we examine citation counts, as a proxy for paper quality, for articles published in four leading international relations journals during the years 2000–2015. We compare citation counts for articles written by “in-group members” (authors affiliated with the journal’s publishing institution) versus “out-group members” (authors not affiliated with that institution). Articles written by in-group authors received 18% to 49% fewer Web of Science citations when published in their home journal (International Security or World Politics) vs. an unaffiliated journal, compared to out-group authors. These results are mainly driven by authors who received their PhDs from Harvard or MIT. The findings show evidence of a bias within some journals towards publishing papers by faculty from their home institution, at the expense of paper quality.  相似文献

Scopus and Web of Science are the two major citation databases that collect and disseminate bibliometric statistics about research articles, journals, institutions, and individual authors. Liaison librarians are now regularly called upon to utilize these databases to assist faculty in finding citation activity on their published works for tenure and promotion, grant applications, and more. But questions about the accuracy, scope, and coverage of these tools deserve closer scrutiny. Discrepancies in citation capture led to a systematic study on how Scopus and Web of Science compared in a real-life situation encountered by liaisons: comparing three different disciplines at a medical school and nursing program. How many articles would each database retrieve for each faculty member using the author-searching tools provided? How many cited references for each faculty member would each tool generate? Results demonstrated troubling differences in publication and citation activity capture between Scopus and Web of Science. Implications for librarians are discussed.  相似文献

The references cited in scientific articles are as important as any other part of the paper, because of their usefulness to the scientific community and to abstracting and indexing services and citation databases. I studied inaccuracies in references and in‐text citations in sample of 97 of the 519 peer‐reviewed journals accredited by the Iranian National Commission for Journal Accreditation Policy (Ministry of Research, Science and Technology). The target journals published 2,980 articles with 74,577 cited references and 108,151 in‐text citations. The results showed 36.6% as the average percentage error rate (range 5.6% to 61.3%). The mean number of errors in cited reference and in‐text citations was 2.7 per article, and the mean number of errors per journal was 690. For the entire sample of articles, 4,369 in‐text citations did not match any source in the list of references (4%), and 8,683 cited references did not match any in‐text citation (11.6%). The stakeholders in scholarly communication, especially authors, pay insufficient attention to the accuracy of bibliographic references. Peer‐reviewed journals should encourage the use of standardized journal policies and quality‐control measures regarding peer review, data quality and accuracy.  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

PurposeThis paper aims to examine whether Altmetric data can be used as an indicator for identifying predatory journals.Design/methodology/approachThis is an applied study which uses citation and Altmetrics methods. The study selected 21 predatory journals from the Beall's list and Kscien's list, as well as 18 non-predatory open access journals from the DOAJ's list, in the field of Library and Information Science. The Altmetric score for articles published in these journals was obtained from the Altmetric Explorer, a service provided by Altmetric.com. Web of Science was used to search for citation data of articles published in these journals.FindingsThe predatory journals almost have no presence in social media, with poor Altmetric score. In contrast, non-predatory open access journals have a high presence rate and Altmetric score. There is a significant positive correlation between the number of articles cited and the number of articles having Altmetric score among non-predatory open-access journals, but not among predatory journals. Poor Altmetric score may be viewed as a potential characteristic of predatory journals, but other indicators would also need to be considered to determine whether a journal is predatory.Originality/valueDistinct from the traditional research methods, this study combined citation analysis and Altmetrics analysis. By comparing the characteristics of predatory journals and non-predatory open access journals, the findings contribute to the identification of predatory journals.  相似文献

OBJECTIVES: This 1990-1991 study explored the relationship between the size of health sciences library journal collections and the number of different journals cited by medical school faculty in departments of biochemistry and medicine. METHODS: Two regression equations, including variables associated with a national stratified sample of 622 faculty who published articles during those two years, were used to explore factors correlated with variations in faculty use of the journal literature and faculty publishing productivity. RESULTS: Results suggest that, after controlling for other variables in the models, neither the number of different journals those faculty cited, nor the number of articles they published, had statistically significant correlations with the number of journals in the health sciences library collection. CONCLUSION: The traditional view that the size of an academic health sciences library's journal collection is a good measure of how well that library is positioned to support faculty research may not be entirely accurate.  相似文献

Analysis of 131 publications during 2006–2007 by staff of the School of Environmental Science and Management at Southern Cross University reveals that the journal impact factor, article length and type (i.e., article or review), and journal self-citations affect the citations accrued to 2012. Authors seeking to be well cited should aim to write comprehensive and substantial review articles, and submit them to journals with a high impact factor which has previously carried articles on the topic. Nonetheless, strategic placement of articles is complementary to, and no substitute for careful crafting of good quality research. Evidence remains equivocal regarding the contribution of an author's prior publication success (h-index) and of open-access journals.  相似文献

Using 17 open-access journals published without interruption between 2000 and 2004 in the field of library and information science, this study compares the pattern of cited/citing hyperlinked references of Web-based scholarly electronic articles under various citation ranges in terms of language, file format, source and top-level domain. While the patterns of cited references were manually examined by counting the live hyperlinked-cited references, the patterns of citing references were examined by using the cited by tag in Google Scholar. The analysis indicates that although language, top-level domain, and file format of citations did not differ significantly for articles under different citation ranges, sources of citation differed significantly for articles in different citation ranges. Articles with fewer citations mostly cite less-scholarly sources such as Web pages, whereas articles with a higher number of citations mostly cite scholarly sources such as journal articles, etc. The findings suggest that 8 out of 17 OA journals in LIS have significant research impact in the scholarly communication process.  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

The journal impact factor (JIF) reported in journal citation reports has been used to represent the influence and prestige of a journal. Whereas the consideration of the stochastic nature of a statistic is a prerequisite for statistical inference, the estimation of JIF uncertainty is necessary yet unavailable for comparing the impact among journals. Using journals in the Database of Research in Science Education (DoRISE), the current study proposes bootstrap methods to estimate the JIF variability. The paper also provides a comprehensive exposition of the sources of JIF variability. The collections of articles in the year of interest and in the preceding years both contribute to JIF variability. In addition, the variability estimate differs depending on the way a database selects its journals for inclusion. In the bootstrap process, the nested structure of articles in a journal was accounted for to ensure that each bootstrap replication reflects the actual citation characteristics of articles in the journal. In conclusion, the proposed point and interval estimates of the JIF statistic are obtained and more informative inferences on the impact of journals can be drawn.  相似文献

In this study, we identified and analyzed characteristics of top-cited single-author articles published in the Science Citation Index Expanded from 1991 to 2010. A top-cited single-author article was defined as an article that had been cited at least 1000 times from the time of its publication to 2012. Results showed that 1760 top-cited single-author articles were published in 539 journals listed in 130 Web of Science categories between 1901 and 2010. The top productive journal was Science and the most productive category was multidisciplinary physics. Most of the articles were not published in high-impact journals. Harvard University led all other institutions in publishing top-cited single-author articles. Nobel Prize winners contributed 7.0% of articles. In total, 72 Nobel Prize winners published 124 single-author articles. Single-authored papers published in different periods exhibited different patterns of citation trends. However, top-cited articles consistently showed repetitive peaks regardless of the time period of publication. “Theory (or theories)” was the most frequently appeared title word of all time. Leading title words varied at different time periods, and only five title words, method(s), protein(s), structure(s), molecular, and quantum consistently remained in the top 20 in different time periods.  相似文献

The purpose of the study was to investigate and compare the social media (SM) impact of 273 South Africa Post-Secondary Education accredited journals, which are recognised by the Department of Higher Education and Training of South Africa for purposes of financial support. We used multiple sources to extract data for the study, namely, Altmetric.com, Google Scholar (GS), Scopus (through SCImago) and the Thomson Reuters (TR) Journal Citation Reports (JCR). Data was analysed to determine South African journals’ presence in and impact on SM as well as to contrast SM visibility and impact with the citation impact in GS, JCR and Scopus. The Spearman correlation test was performed to compare the impact of the journals on SM and other sources. The results reveal that 2923 articles published in 122 of the 273 South African (SA) journals have received at least one mention in SM; the most commonly used SM platforms were Twitter and Facebook; the journals indexed in the TR’s citation indexes and Scopus performed much better, in terms of their average altmetrics, than non-TR and non-Scopus indexed journals; and there were weak to moderate relationships among different types of altmetrics and citation-based measures, thereby implying different kinds of journal impacts on SM when compared to the scholarly impact reflected in citation databases. In conclusion, South African journals’ impact on SM, just as is the case with countries with similar economies, is minimal but has shown signs of growth.  相似文献
