Online journals' impact on the citation patterns of medical faculty.

PURPOSE: The purpose was to determine the impact of online journals on the citation patterns of medical faculty. This study looked at whether researchers were more likely to limit the resources they consulted and cited to those journals available online rather than those only in print. SETTING: Faculty publications from the college of medicine at a large urban university were examined for this study. The faculty publications from a regional medical college of the same university were also examined in the study. The number of online journals available for faculty, staff, and students at this institution has increased from an initial core of 15 online journals in 1998 to over 11,000 online journals in 2004. METHODOLOGY: Searches by author affiliation were performed in the Web of Science to find all articles written by faculty members in the college of medicine at the selected institution. Searches were conducted for the following years: 1993, 1996, 1999, and 2002. Cited references from each faculty-authored article were recorded, and the corresponding cited journals were coded into four categories based on their availability at the institution in this study: print only, print and online, online only, and not owned. Results were analyzed using SPSS. RESULTS: The number of journals cited per year continued to increase from 1993 to 2002. The results did not indicate that researchers were more likely to cite online journals or were less likely to cite journals only in print. At the regional location where the number of print-only journals was minimal, use of the print-only journals did decrease in 2002, although not significantly. CONCLUSION/DISCUSSION: It is possible that electronic access to information (i.e., online databases) has had a positive impact on the number of articles faculty will cite. Results of this study suggest, at this point, that faculty are still accessing the print-only collection, at least for research purposes, and are therefore not sacrificing quality for convenience.     

Interdisciplinarity as diversity in citation patterns among journals: Rao-Stirling diversity,relative variety,and the Gini coefficient

Questions of definition and measurement continue to constrain a consensus on the measurement of interdisciplinarity. Using Rao-Stirling (RS) Diversity sometimes produces anomalous results. We argue that these unexpected outcomes can be related to the use of “dual-concept diversity” which combines “variety” and “balance” in the definitions (ex ante). We propose to modify RS Diversity into a new indicator (DIV) which operationalizes “variety,” “balance,” and “disparity” independently and then combines them ex post. “Balance” can be measured using the Gini coefficient. We apply DIV to the aggregated citation patterns of 11,487 journals covered by the Journal Citation Reports 2016 of the Science Citation Index and the Social Sciences Citation Index as an empirical domain and, in more detail, to the citation patterns of 85 journals assigned to the Web-of-Science category “information science & library science” in both the cited and citing directions. We compare the results of the indicators and show that DIV provides improved results in terms of distinguishing between interdisciplinary knowledge integration (citing references) versus knowledge diffusion (cited impact). The new diversity indicator and RS diversity measure different features. A routine for the measurement of the various operationalization of diversity (in any data matrix) is made available online.     

Use of faculty publication lists and ISI citation data to identify a core list of journals with local importance

A method was developed to rank journals in a specific subject area, molecular and cellular biology (MCB), in order to create a core list of journals for the MCB faculty of the Pennsylvania State University. The core list of journals was needed as the first step in a larger serials evaluation process. The method did not require use data, but incorporated various quality measures, including publication in journals by Penn State faculty, citings of journals by Penn State faculty, and Journal Citation Report data from ISI. This study produced a core list of 50 MCB journals, as well as other benefits. Although the list of core MCB journals derived from this study is specific to the needs of Penn State faculty, the method could be adapted to other situations.     

Measuring contextual citation impact of scientific journals

This paper explores a new indicator of journal citation impact, denoted as source normalized impact per paper (SNIP). It measures a journal's contextual citation impact, taking into account characteristics of its properly defined subject field, especially the frequency at which authors cite other papers in their reference lists, the rapidity of maturing of citation impact, and the extent to which a database used for the assessment covers the field's literature. It further develops Eugene Garfield's notions of a field's ‘citation potential’ defined as the average length of references lists in a field and determining the probability of being cited, and the need in fair performance assessments to correct for differences between subject fields. A journal's subject field is defined as the set of papers citing that journal. SNIP is defined as the ratio of the journal's citation count per paper and the citation potential in its subject field. It aims to allow direct comparison of sources in different subject fields. Citation potential is shown to vary not only between journal subject categories – groupings of journals sharing a research field – or disciplines (e.g., journals in mathematics, engineering and social sciences tend to have lower values than titles in life sciences), but also between journals within the same subject category. For instance, basic journals tend to show higher citation potentials than applied or clinical journals, and journals covering emerging topics higher than periodicals in classical subjects or more general journals. SNIP corrects for such differences. Its strengths and limitations are critically discussed, and suggestions are made for further research. All empirical results are derived from Elsevier's Scopus.     

Publication and citation patterns among LIS faculty: Profiling a “typical professor”

Research on publication and citation patterns generally focuses on prolific or highly cited authors or on highly ranked programs. This study investigates the work and influence of a cross-section of library and information science (LIS) researchers at various stages of their academic lives, using a random sample of faculty members at programs accredited by the American Library Association. The analysis shows that the number of publications increases steadily as faculty rank advances. Assistant professors publish more conference papers and fewer journal articles, a pattern that is reversed with associate and full professors. Researchers used Web of Science® and Google™ Scholar to determine the influence of the publications. Web of Science reported no citations for most LIS faculty publications. With its broader scope, Google Scholar located more citations and revealed that the works of professors are cited significantly more frequently than publications by assistant or associate professors. When faculty profiles are compared by type of program, faculty members at schools granting doctoral degrees publish significantly more than their counterparts at schools where there is no doctoral program or where the doctoral degree is offered jointly with other academic units. When the comparison is made across ranks, full professors publish significantly more than faculty members at other ranks. There is no significant difference between assistant and associate professors.     

The archiving of online journals

The present lack of trusted archiving of electronic periodicals is probably one of the main factors preventing a faster move away from the printed journal. This article considers – from a publisher's and a librarian's perspective – all aspects of the electronic archiving, from what should be archived, to who should carry out the archiving.

2008-2013年中外科技期刊载文与引证指标分析

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.     

Rating Pakistani medical journals using the principles of citation analysis

OBJECTIVE: To quantify the impact of Pakistani Medical Journals using the principles of citation analysis. METHODS: References of articles published in 2006 in three selected Pakistani medical journals were collected and examined. The number of citations for each Pakistani medical journal was totalled. The first ranking of journals was based on the total number of citations; second ranking was based on impact factor 2006 and third ranking was based on the 5-year impact factor. Self-citations were excluded in all the three ratings. RESULTS: A total of 9079 citations in 567 articles were examined. Forty-nine separate Pakistani medical journals were cited. The Journal of the Pakistan Medical Association remains on the top in all three rankings, while Journal of College of Physicians and Surgeons-Pakistan attains second position in the ranking based on the total number of citations. The Pakistan Journal of Medical Sciences moves to second position in the ranking based on the impact factor 2006. The Journal of Ayub Medical College, Abbottabad moves to second position in the ranking based on the 5-year impact factor. CONCLUSION: This study examined the citation pattern of Pakistani medical journals. The impact factor, despite its limitations, is a valid indicator of quality for journals.

Assessment of drug information resource preferences of pharmacy students and faculty

A 39-item survey instrument was distributed to faculty and students at Wingate University School of Pharmacy to assess student and faculty drug information (DI) resource use and access preferences. The response rate was 81% (n = 289). Faculty and professional year 2 to 4 students preferred access on laptop or desktop computers (67% and 75%, respectively), followed by smartphones (27% and 22%, respectively). Most faculty and students preferred using Lexicomp Online for drug information (53% and 74%, respectively). Results indicate that DI resources use is similar between students and faculty; laptop or desktop computers are the preferred platforms for accessing drug information.     

The performance of Asian S&T journals in international citation indicators

This research explores the performance of Asian S&T journals based on the outcomes of various citation indicators. Indexed by Journal Citation Reports – Science Citation Index Expanded (JCR‐SCIE), journals published in China, Japan, India, Singapore, South Korea, and Taiwan between the years 2008 and 2012 are collected and analysed using bibliometrics and statistics methods. Results showed that the mean impact factor (IF) value of the journals from all countries was less than 1.3 throughout the period. Only journals from China and Japan had a mean IF or 5‐year IF (5Y‐IF) value exceeding 1. The self‐cited rate of the journals from South Korea remained the highest among selected countries but showed a declining trend every year. The self‐cited rates among journals from all the six Asian countries did not considerably affect the journals’ IF values. The results revealed that the IF‐based ranking factor (IF‐RF) of Chinese and Japanese journals in various subject fields constantly improved from 2008 to 2012, but this improvement trend was not observed in journals from the other four countries. Overall, the journals from Japan and China demonstrated stronger impacts than those from the other countries.     

The citation impact of the Open Access accounting journals that appear on Beall's List of potentially predatory publishers and journals

Although there are at least six dimensions of journal quality, Beall's List identifies predatory Open Access journals based almost entirely on their adherence to procedural norms. The journals identified as predatory by one standard may be regarded as legitimate by other standards. This study examines the scholarly impact of the 58 accounting journals on Beall's List, calculating citations per article and estimating CiteScore percentile using Google Scholar data for more than 13,000 articles published from 2015 through 2018. Most Beall's List accounting journals have only modest citation impact, with an average estimated CiteScore in the 11th percentile among Scopus accounting journals. Some have a substantially greater impact, however. Six journals have estimated CiteScores at or above the 25th percentile, and two have scores at or above the 30th percentile. Moreover, there is considerable variation in citation impact among the articles within each journal, and high-impact articles (cited up to several hundred times) have appeared even in some of the Beall's List accounting journals with low citation rates. Further research is needed to determine how well the citing journals are integrated into the disciplinary citation network—whether the citing journals are themselves reputable or not.
