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. 相似文献

基于开放牛津期刊的开放获取引用优势分析 总被引：1，自引：0，他引：1
本文以"开放牛津"的93种混合型期刊为研究样本,对其2009年刊载的全部论文的被引频次进行统计分析,以验证关于开放获取引用优势(OACA)的三个假设:存在开放获取引用优势;不同学科的OACA不同;OACA与期刊影响因子有相关性。通过研究发现:开放牛津期刊存在OACA,开放牛津期刊中的OA论文与非OA论文相比有138.87%的引用优势;五个学科领域的开放牛津期刊的OACA存在差异(其中人文科学不存在OACA);开放获取引用优势与期刊影响因子之间具有显著的逆函数关系,即随着期刊影响因子的增长,开放获取引用优势呈下降趋势。 相似文献

Articles published behind a paywall in commercial journals are often inaccessible to potential readers who are not affiliated with a subscribing institution. Open Access Button is an application that assists readers in finding Open Access versions of such articles. This service works in a completely legal fashion. This interview is with one of the co-founders of the service, Joe McArthur. Open Access Button is supported by the Scholarly Publishing and Academic Resources Coalition. 相似文献

ABSTRACTAcademic libraries provide intellectual access (discovery and procurement) to the full text of electronic journal articles through traditional library technologies like discovery layers, link resolver software and knowledge bases. These technologies mainly rely on accurate title-level metadata to successfully deliver journal articles to library users. Open Access articles pose a difficulty for many participants in the e-journal supply chain, including libraries and publishers, as Open Access status is a property of the article, not the title. A review of the literature examines: the impact of Open Access on intellectual access through traditional library technologies, current proposed solutions, and emerging technologies. 相似文献

This research provides insight into the complex relationship between open access, funding, and citation advantage. It presents an analysis of research articles and their citations in the Scopus database across 40 subject categories. The sample includes 12 categories from Health Sciences, 7 from Life Sciences, 10 from Physical Sciences & Engineering, and 11 from Social Sciences & Humanities. Specifically, the analysis focuses on articles published in 2016 and the citations they received from 2016 to 2020. Our findings show that open access articles published in hybrid journals receive considerably more citations than those published in gold open access journals. Articles under the hybrid gold modality are cited on average twice as much as those in the gold modality, regardless of funding. Furthermore, we found that funded articles generally obtain 50 % more citations than unfunded ones within the same publication modality. Open access repositories significantly increase citations, particularly for articles without funding. Thus, articles in open access repositories receive 50 % more citations than paywalled ones. 相似文献

This article uses Google Scholar (GS) as a source of data to analyse Open Access (OA) levels across all countries and fields of research. All articles and reviews with a DOI and published in 2009 or 2014 and covered by the three main citation indexes in the Web of Science (2,269,022 documents) were selected for study. The links to freely available versions of these documents displayed in GS were collected. To differentiate between more reliable (sustainable and legal) forms of access and less reliable ones, the data extracted from GS was combined with information available in DOAJ, CrossRef, OpenDOAR, and ROAR. This allowed us to distinguish the percentage of documents in our sample that are made OA by the publisher (23.1%, including Gold, Hybrid, Delayed, and Bronze OA) from those available as Green OA (17.6%), and those available from other sources (40.6%, mainly due to ResearchGate). The data shows an overall free availability of 54.6%, with important differences at the country and subject category levels. The data extracted from GS yielded very similar results to those found by other studies that analysed similar samples of documents, but employed different methods to find evidence of OA, thus suggesting a relative consistency among methods. 相似文献

A citation analysis study was conducted on faculty publications from Business School at Institution. Citations were analyzed by format of materials, library availability, journal concentration by department and the citation age of the journal articles. This study was undertaken in an effort to guide local collection development knowledge, compare how departments in the business school used different resources, and illustrate trends in business faculty citations as compared to similar studies. The study was also conducted in order to enable business librarians to be able to understand, anticipate, and respond to faculty research needs in the business school. 相似文献

Students and scholars can take full advantage of Open Access journals only if libraries make them available through mechanisms that are familiar to patrons. This study examines the extent to which American liberal arts colleges have provided access to Open Access journals through their journal title lists (Serials Solutions, Ex Libris, etc.) and their online public access catalogs (OPACs). While 57 percent of the colleges provide access to at least 90 percent of the journals in our sample, 20 percent of the colleges provide access to fewer than 20 percent of the journals. Large and high-impact journals are especially likely to appear in libraries' catalogs and journal lists. There is no systematic trend by publication fee status or country of publication, however. The study concludes with a discussion of the strategies libraries can use to select Open Access journals and add them to their collections. 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

InCites Essential Science Indicators is becoming increasingly used to identify top-performing research and evaluate the impact of institutes. Unfortunately, our study shows that ESI indicators, as well as other normalized citation indicators, have the following flaws. First, the publication month and the online-to-print delay affect a paper’s probability of becoming a Highly Cited Paper (HCP). Papers published in the earlier months of the year are more likely to accumulate enough citation counts to rank at the top 1% compared with those published in later months of the year. Papers with longer online-to-print delays have an apparent advantage for being selected as HCPs. Research field normalizations lead to the third pitfall. Different research fields have different citation thresholds for HCPs, making research field classification important for a journal. In addition, the uniform thresholds for both articles and reviews in ESI affect the reliability of HCP selection because, on average, reviews tend to have higher citation rates than articles. ESI’s selection of HCPs provides an intuitive feel for the problems of normalized citation impact indicators, such as those provided in InCites and SciVal. 相似文献

Hybrid Journals: Ensuring Systematic and Standard Discoverability of the Latest Open Access Articles
An important current challenge for research information providers is ensuring the automated discovery of Open Access (OA) content in hybrid journals. We found no evidence of discovery services that are able to systematically identify the crucially important free full-text availability of OA articles regardless of where and how such articles have been published (i.e., in fully OA journals or in hybrid journals). A solution is important because hybrid journals are proliferating and consequently the chances of missing OA articles is real and is happening. Nearly all of the major publishers now provide such journals in order to take advantage of recent changes in research funder requirements, and to be competitive in the new OA business model. By working with a group of scholarly publisher partners and by using standard metadata elements that publishers are already familiar with, we show a systematic and standardized manner to identify OA at the article level. Our proposal is to embed OA-related elements in the metadata freely exposed by publishers for aggregators and discovery services. For example, in the Table of Content (TOC) Really Simple Syndication feeds the publishers use to announce new journal issues and content. Based on the initial results obtained, we discuss the capabilities of our solution, and evaluate the impact produced by our application in the systematic discoverability of OA content from the participating hybrid journals, using an implementation done with the freely available journal current awareness service—JournalTOCs. 相似文献

We report characteristics of in-text citations in over five million full text articles from two large databases – the PubMed Central Open Access subset and Elsevier journals – as functions of time, textual progression, and scientific field. The purpose of this study is to understand the characteristics of in-text citations in a detailed way prior to pursuing other studies focused on answering more substantive research questions. As such, we have analyzed in-text citations in several ways and report many findings here. Perhaps most significantly, we find that there are large field-level differences that are reflected in position within the text, citation interval (or reference age), and citation counts of references. In general, the fields of Biomedical and Health Sciences, Life and Earth Sciences, and Physical Sciences and Engineering have similar reference distributions, although they vary in their specifics. The two remaining fields, Mathematics and Computer Science and Social Science and Humanities, have different reference distributions from the other three fields and between themselves. We also show that in all fields the numbers of sentences, references, and in-text mentions per article have increased over time, and that there are field-level and temporal differences in the numbers of in-text mentions per reference. A final finding is that references mentioned only once tend to be much more highly cited than those mentioned multiple times. 相似文献

It is widely believed that collaboration is advantageous in science, for example, with collaboratively written articles tending to attract more citations than solo articles and strong arguments for the value of interdisciplinary collaboration. Nevertheless, it is not known whether the same is true for research that produces books. This article tests whether co-authored scholarly monographs attract more citations than solo monographs using books published before 2011 from 30 categories in the Web of Science. The results show that solo monographs numerically dominate collaborative monographs, but give no evidence of a citation advantage for collaboration on monographs. In contrast, for nearly all these subjects (28 out of 30) there was a citation advantage for collaboratively produced journal articles. As a result, research managers and funders should not incentivise collaborative research in book-based subjects or in research that aims to produce monographs, but should allow the researchers themselves to freely decide whether to collaborate or not. 相似文献
