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

During the past twenty years, more than ninety retraction notices have been published in biomedical journals. These retractions constitute a unique body of literature that biomedical researchers, bibliographers, and librarians must monitor to reduce scientific use of retracted, invalid papers. An analysis of medical retraction notices shows that very few are prominent in style, format, or placement, in spite of authoritative publication standards formulated by the International Council of Medical Journal Editors. Although researchers are ultimately responsible for the validity of the information they cite in their own publications, biomedical librarians are in a unique position to educate their patrons regarding retracted papers. 相似文献

This study explored national differences in plagiarism and duplicate publication in retracted biomedical literature. The national affiliations of authors and reasons for retraction of papers accessible through PubMed that were published from 2008 to 2012 and subsequently retracted were determined in order to identify countries with the largest numbers and highest rates of retraction due to plagiarism and duplicate publication. Authors from more than fifty countries retracted papers. While the United States retracted the most papers, China retracted the most papers for plagiarism and duplicate publication. Rates of plagiarism and duplicate publication were highest in Italy and Finland, respectively. Unethical publishing practices cut across nations. 相似文献

The promotion of scholarly journal articles to journalists and bloggers via the dissemination of press releases generates a positive impact on the number of citations that publicized journal articles receive. Research by John Wiley & Sons, Inc. shows that article‐level publicity efforts and media coverage boosts downloads by an average of 1.8 times and were found to increase citations by as much as 2.0–2.2 times in the articles analyzed in this study. We evaluated scholarly journal articles published in nearly 100 Wiley journals, which were also covered in 296 press releases. The results in this case study suggest a need for greater investment in media support for scholarly journals publishing research that sparks interest to a broad news audience, as it could increase citations. 相似文献

Many journals post accepted articles online before they are formally published in an issue. Early citation impact evidence for these articles could be helpful for timely research evaluation and to identify potentially important articles that quickly attract many citations. This article investigates whether Microsoft Academic can help with this task. For over 65,000 Scopus in-press articles from 2016 and 2017 across 26 fields, Microsoft Academic found 2–5 times as many citations as Scopus, depending on year and field. From manual checks of 1122 Microsoft Academic citations not found in Scopus, Microsoft Academic’s citation indexing was faster but not much wider than Scopus for journals. It achieved this by associating citations to preprints with their subsequent in-press versions and by extracting citations from in-press articles. In some fields its coverage of scholarly digital libraries, such as arXiv.org, was also an advantage. Thus, Microsoft Academic seems to be a more comprehensive automatic source of citation counts for in-press articles than Scopus. 相似文献

While researchers with retracted papers – publications that are withdrawn because of significant errors or scientific misconduct – carry a permanent stain on their publishing records, understanding the causes and initiators of such retractions can shed a different light on the matter. This paper, based on a random sample of 2,046 retracted papers, which were published between 1975 and 2019, extracted from Retraction Watch and the websites of major publishers, shows that 53% of the retraction notices do not specify who initiated the retraction. Nearly 10% of the retraction notes either omit or do not contain information related to reasons for retractions. Furthermore, most of the retracted papers in our sample have no limitation section; those who do are commonly unhelpful or irrelevant. The results carry three implications for scientific transparency: retraction notices need to be more informative; limitation sections ought to be a required and even an open section of all published articles; and finally, promoting ‘heroic acts’ in science can positively change the current publishing culture. 相似文献

OBJECTIVES: To explore how often newspapers cover the retraction of a medical journal article and whether newspaper coverage corresponds with the appearance of a press release about the retraction. METHODS: Fifty citations were identified in PubMed that had been indexed with the Medical Subject Heading 'Retracted Publication'. Next, the archives of LexisNexis's 'Major Newspapers' and EurekAlert's press releases were searched to find references to those retracted publications. RESULTS: Newspaper articles addressed exactly three of the 50 retracted publications, and press releases, exactly four of the 50 retracted publications. All three retracted publications that received newspaper coverage also had a press release. In other words, newspapers only covered a retraction that had been introduced by a press release. CONCLUSION: One would expect that newspaper coverage would increase after a press release, but the suggested relationships among a medical journal article retraction, a press release and newspaper coverage should be further investigated. If the linkage suggested by the data of this study holds, and if newspaper coverage stimulates library patron interest, then a medical library might prepare itself for information requests following a press release. 相似文献

Purpose: The purpose is to review the issue of retraction in the scientific literature and to examine the policies on retraction of major biomedical journals.Method: The historical background of this issue was investigated through a literature search. The Instructions to Authors of 122 major biomedical journals were reviewed for evidence of a policy on the retraction of articles. Editors of those journals with no mention of retraction in their Instructions to Authors were contacted by email and/or postal mail.Results: Sixty-two percent of the journals investigated did not post or report having a policy on issuing retractions. Only twenty-one (18%) did. The remainder did not post any policy and did not respond to inquiries.Discussion: Including policies in Instructions to Authors relating to the principled conduct of research and publication will improve the ethical environment in which the scientific community works. 相似文献

Penetration of Nigerian predatory biomedical open access journals 2007–2012: a bibliometric study 
下载免费PDF全文
下载免费PDF全文 This paper presents the bibliometric characteristics of 32 biomedical open access journals published by Academic Journals and International Research Journals – the two Nigerian publishers in Jeffery Beall's list of 23 predatory open access publishers in 2012. Data about the journals and the authors of their articles were collected from the websites of the publishers, Google Scholar and Web of Science. As at December 2012, the journals had together produced a total of 5,601 papers written by 5,599 authors, and received 12,596 citations. Authors from Asia accounted for 56.79% of the publications; those from Africa wrote 28.35% while Europe contributed 7.78%. Authors from Africa accounted for 18.25% of the citations these journals received, and this is about one‐third the number of citations by authors in Asia (54.62%). At country level, India ranks first in the top 10 citer countries, while Nigeria, the host country of the journals, ranked eighth. More in‐depth studies are required to develop further information about the journals such as how much scientific information the journals contain, as well as the science literacy of the authors and the editorial. 相似文献

This paper considers a new model for forming ranked lists of scientific journals on the basis of a bibliometric analysis. The model is based on searching in anabstract database of a set of articles that is semantically equivalent to a set of articles of a user or group of users, for whom a repertoire of scientific periodicals is selected. In other words, a query must result in an assembly of articles with the same thematic orientation, which is expressed in the articles of an author. To achieve this goal, KeyWords Plus were used as a query for articles by workers from three scientific organizations in different scientific fields (biomedical, geological, and physico-mathematical fields). KeyWords Plus, which give a short retelling of each article, are joined in a query into groups, whose number was correspondingly equal to the number of articles of workers from these organizations. The query yielded lists of articles withthe same sequences of keywords, which proved their semantic proximity. Using different filters we analyzed the groups of journals that focused articles that are of interest to us to the greatest extent. The obtained lists were compared with the lists of journals that are most cited by the authors of the articles; the similarity of the lists in the field of natural sciences was ascertained to be significant and the similarity in the field of exact sciences was shown to be less. The possible spheres for the application of the KeyWords Plus method, which is an alternative to an analysis of citations, as well as the applicability of a new model to the Scopus database, where controlled thesauri are used as additional keywords, are described. 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

Study investigates the availability, persistence and half life of URL citations cited in two Indian LIS journals articles published between 2002 and 2010. This study also investigates how researchers can resurrect lapsed URL citations cited in research articles, using Wayback machine. A total of 1290 URLs cited in 472 research articles published in Indian LIS journals spanning a period of 9 years (2002–2010) were extracted. Study found that only 18.91% (1290 out of 6820) of URLs cited in these journal articles. 39.84% of URL citations were not accessible and remaining 60.15% of URL citations were still accessible. The HTTP 404 error message-“page not found” was the overwhelming message encountered and represented 54.86% of all HTTP error messages. However 51.06% URLs were recovered from HTTP 404 error message. Study also noticed that the half-life of URL citations was increased from 6.33 years to 13.85 years after recovering missing URLs from Wayback machine. 相似文献

This study investigates the decay and half-life of online citations cited in four open access journals published between 2000 and 2009. A total of 1158 online citations cited in 1086 research articles published in two science and social science journals spanning a period of 10 years (2000–2009) were extracted. Study found that 24.58% (267 out of 1086) of articles had online citations and these articles contained a substantially very less number of online citations (2.98%) compared to previous study results. 30.56% (26% in Science and 52.73% in Social Science) of online citations were not accessible and remaining 69.44% of online citations were still accessible. The ‘HTTP 404 error message-page not found’ was the overwhelming message encountered and represented 67.79% of all HTTP message. Domains associated with .ac and .net had higher successful access rates while .org and .com/.co had lowest successful access rates. The half-life of online citations was computed to be approximately 11.5 years and 9.07 years in Science and Social science journal articles respectively. 相似文献

The Web impact of open access social science research 总被引：1，自引：0，他引：1
For a long time, Institute for Scientific Information (ISI) journal citations have been widely used for research performance monitoring of the sciences. For the social sciences, however, the Social Sciences Citation Index® (SSCI®) can sometimes be insufficient. Broader types of publications (e.g., books and non-ISI journals) and informal scholarly indicators may also be needed. This article investigates whether the Web can help to fill this gap. The authors analyzed 1530 citations from Google™ to 492 research articles from 44 open access social science journals. The articles were published in 2001 in the fields of education, psychology, sociology, and economics. About 19% of the Web citations represented formal impact equivalent to journal citations, and 11% were more informal indicators of impact. The average was about 3 formal and 2 informal impact citations per article. Although the proportions of formal and informal online impact were similar in sociology, psychology, and education, economics showed six times more formal impact than informal impact. The results suggest that new types of citation information and informal scholarly indictors could be extracted from the Web for the social sciences. Since these form only a small proportion of the Web citations, however, Web citation counts should first be processed to remove irrelevant citations. This can be a time-consuming process unless automated. 相似文献
