In this paper, we conduct a comparative analysis to examine the characteristics and evolutionary trends of open access (OA) publications in natural and social sciences. We use data recorded by Science Citation Index Expanded, Social Sciences Citation Index, and Journal Citation Reports during 2001–2015 as the main source. We then comparatively analyse the characteristics of natural and social sciences in terms of historical evolution, main contributors, and distribution of OA journals and publications across different languages, disciplines, and impact factor quartiles. Our results suggest that both natural and social sciences experienced dramatic growth of OA journals since 2009, but the share of social science OA journals within journal impact factor quartile 1 is much lower than that of natural sciences. While natural and social sciences share some similarities in OA publishing activities, such as main countries of contribution, they differ greatly in dimensions such as OA ratio across specific disciplines, countries, and publishing languages. We acknowledge that OA publishing offers a level playing field for traditionally disadvantaged languages, countries, and scientific disciplines, but meanwhile, the advancement of high‐quality OA publishing needs more targeted and sophisticated approaches to tackle differences in natural and social sciences. 相似文献

While self-archiving gains more traction as a means for scholars to make their research freely available, a perception persists that certain disciplines in the humanities lag behind the sciences in this regard. This article investigates the rate of self-archiving by scholars contributing to the top journals in the field of music, a discipline that traditionally falls within the humanities, although research in the field is highly interdisciplinary and draws heavily on multiple scientific fields. The contributors to these journals come from a range of background and interests, and represent colleges and universities from six continents. 相似文献

标准化影响因子在不同学科期刊比较中的应用 总被引：3，自引：0，他引：3
影响因子被用来评价科技期刊、科研人员及科研机构的学术水平,但由于学科间规模、发展速度不同,导致不同学科的期刊拥有不同的半衰期和文献利用规律,因此把影响因子直接用于不同学科间期刊的评价是不公平的.为了避免这种不公平,提出了"标准化影响因子"的概念,它通过对科技期刊的影响因子进行一次非线性转换和线性转换而得到,可以减小影响因子在评价不同学科期刊时的误差. 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

A similarity comparison is made between 120 journals from five allied Web of Science disciplines (Communication, Computer Science-Information Systems, Education & Educational Research, Information Science & Library Science, Management) and a more distant discipline (Geology) across three time periods using a novel method called citing discipline analysis that relies on the frequency distribution of Web of Science Research Areas for citing articles. Similarities among journals are evaluated using multidimensional scaling with hierarchical cluster analysis and Principal Component Analysis. The resulting visualizations and groupings reveal clusters that align with the discipline assignments for the journals for four of the six disciplines, but also greater overlaps among some journals for two of the disciplines or categorizations that do not necessarily align with their assigned disciplines. Some journals categorized into a single given discipline were found to be more closely aligned with other disciplines and some journals assigned to multiple disciplines more closely aligned with only one of the assigned disciplines. The proposed method offers a complementary way to more traditional methods such as journal co-citation analysis to compare journal similarity using data that are readily available through Web of Science. 相似文献

The journal impact factor (JIF) has been questioned considerably during its development in the past half-century because of its inconsistency with scholarly reputation evaluations of scientific journals. This paper proposes a publication delay adjusted impact factor (PDAIF) which takes publication delay into consideration to reduce the negative effect on the quality of the impact factor determination. Based on citation data collected from Journal Citation Reports and publication delay data extracted from the journals’ official websites, the PDAIFs for journals from business-related disciplines are calculated. The results show that PDAIF values are, on average, more than 50% higher than JIF results. Furthermore, journal ranking based on PDAIF shows very high consistency with reputation-based journal rankings. Moreover, based on a case study of journals published by ELSEVIER and INFORMS, we find that PDAIF will bring a greater impact factor increase for journals with longer publication delay because of reducing that negative influence. Finally, insightful and practical suggestions to shorten the publication delay are provided. 相似文献

The paper articulates the problems of journal publication in a relatively small country such as Romania where locally (i.e. nationally) published journals include most of the national medical scientific output. The starting point was a study ordered by the Cluj University of Medicine and Pharmacy Scientific Council, for the purpose of obtaining an objectively ranked list of all current Romanian biomedical journals that could be used in the evaluation of the scientific activity of the university academic staff. Sixty‐five current biomedical journals were identified—of which more than half were new titles that had appeared over the past 5 years. None of these are included in the Science Citation Index or Journal Citation Reports (JCR). A set of criteria was used for ranking the journals: peer review, inclusion in international databases, publication time lag, language of articles and abstracts, journal specific index and domestic impact factor. The period covered, along with tools and formulas used are presented. The problems of Romanian biomedical journals as well as ways of improving publishing standards are discussed. Also emphasized is the necessity for increased awareness in the medical scholarly community and the role of the library in this respect. 相似文献

Academic librarians tend to publish in traditional “library” journals rather than journals directed at other academic disciplines, thereby missing the opportunity to inform and educate a key audience. This article alerts librarians to publishing opportunities in discipline-specific academic journals in the Arts & Humanities, Sciences, and Social Sciences, both as a means of promoting information literacy (IL) and effecting outreach to faculty. Selection criteria are defined and discussed. The results of the study are presented by discipline in table format with data on each journal including publisher, affiliation, publication frequency, review time, acceptance rate, and ranking indicators. 相似文献

Unlike Impact Factors (IF), Article Influence (AI) scores assign greater weight to citations that appear in highly cited journals. The natural sciences tend to have higher citation rates than the social sciences. We might therefore expect that relative to IF, AI overestimates the citation impact of social science journals in subfields that are related to (and presumably cited in) higher-impact natural science disciplines. This study evaluates that assertion through a set of simple and multiple regressions covering seven social science disciplines: anthropology, communication, economics, education, library and information science, psychology, and sociology. Contrary to expectations, AI underestimates 5IF (five-year Impact Factor) for journals in science-related subfields such as scientific communication, science education, scientometrics, biopsychology, and medical sociology. Journals in these subfields have low AI scores relative to their 5IF values. Moreover, the effect of science-related status is considerable—typically 0.60 5IF units or 0.50 SD. This effect is independent of the more general finding that AI scores underestimate 5IF for higher-impact journals. It is also independent of the very modest curvilinearity in the relationship between AI and 5IF. 相似文献

The status of a journal is commonly determined by two factors: popularity and prestige. While the former counts citations, the latter recursively weights them with the prestige of the citing journals. We make a thorough comparison of the bibliometric concepts of popularity and prestige for journals in the sciences and in the social sciences. We find that the two notions diverge more for the hard sciences, including physics, engineering, material sciences, and computer sciences, than they do for the geosciences, for biology-medical disciplines, and for the social sciences. Moreover, we identify the science and social science journals with the highest diverging ranks in popularity and prestige compilations. 相似文献

We study an agent-based model for generating citation distributions in complex networks of scientific papers, where a fraction of citations is allotted according to the preferential attachment rule (rich get richer) and the remainder is allocated accidentally (purely at random, uniformly). Previously, we derived and analysed such a process in the context of describing individual authors, but now we apply it to scientific journals in computer and information sciences. Based on the large DBLP dataset as well as the CORE (Computing Research and Education Association of Australasia) journal ranking, we find that the impact of journals is correlated with the degree of accidentality of their citation distribution. Citations to impactful journals tend to be more preferential, while citations to lower-ranked journals are distributed in a more accidental manner. Further, applied fields of research such as artificial intelligence seem to be driven by a stronger preferential component – and hence have a higher degree of inequality – than the more theoretical ones, e.g., mathematics and computation theory. 相似文献
