Examines SHERPA/RoMEO publisher open access (OA) policy information for 100 publishers over a 13 year period (2004–2016) to consider whether their size, type or country (UK or US) affected the development of their OA policy over time. A publisher’s RoMEO colour code, whether they offered a Gold OA option, and the mean number of restrictions as to when, how and where papers may be self-archived, were all mapped. Kruskal–Wallis tests were run to assess whether the differences between their 2004 and 2016 positions were statistically significant. Finds that the growth of Green and Gold OA policy approaches has not been evenly distributed amongst publishers with some significant differences amongst publishers of different size, types and country (UK and US). Large commercial publishers are more likely to be allocated a RoMEO colour code, but at the same time place a high volume of restrictions as to where and how authors might self-archive. Small publishers are less likely to have a RoMEO green colour code, but the volume of restrictions they place on self-archiving are minimal. University presses appear not to be engaging with either OA agenda to any considerable degree. UK and US publishers’ OA policies appear to be influenced by the national OA policy environment which, considering the global nature of the scholarly journals market, was more pronounced than might have been anticipated.  相似文献

The current state of open access to journal publications within research areas belonging to the humanities has received relatively little research attention. This study provides a detailed mapping of the bibliometric state of open access to journal publications among ethicists, taking into account not only open access publishing in journals directly, but also where and in what form ethicists make their journal articles available elsewhere on the web. As part of the study 297 ethicists affiliated with top-ranking philosophy departments were identified and their journal publication information for the years 2010–2015 were recorded (1682 unique articles). The journal articles were then queried for through Google Scholar in order to establish open access status (web locations, document versions) of each publication record. Publication records belonging to the 20 most frequently used journal outlets (subset of 597 unique articles) were put under closer inspection with regards to alignment with publisher copyright restrictions as well as measuring unused potential to share articles. The results show that slightly over half of recent journal publications are available to read for free. PhilPapers and academic social networks (Academia.edu and ResearchGate) were found to be key platforms for research dissemination in ethics research. The representation of institutional repositories as providers of access was found to be weak, receiving the second lowest frequency rating among the eight discrete web location categories. Further, the study reveals that ethicists are at the same time prone to copyright infringement and undersharing their scholarly work.  相似文献

Summary We define the URL citations of a Web page to be the mentions of its URL in the text of other Web pages, whether hyperlinked or not. The proportions of formal and informal scholarly motivations for creating URL citations to Library and Information Science open access journal articles were identified. Five characteristics for each source of URL citations equivalent to formal citations were manually extracted and the relationship between Web and conventional citation counts at the e-journal level was examined. Results of Google searches showed that 282 research articles published in the year 2000 in 15 peer-reviewed LIS open access journals were invoked by 3,045 URL citations. Of these URL citations, 43% were created for formal scholarly reasons equivalent to traditional citations and 18% for informal scholarly reasons. Of the sources of URL citations, 82% were in English, 88% were full text papers and 58% were non-HTML documents. Of the URL citations, 60% were text URLs only and 40% were hyperlinked. About 50% of URL citations were created within one year after the publication of the cited e-article. A slight correlation was found between average numbers of URL citations and average numbers of ISI citations for the journals in 2000. Separating out the citing HTML and non-HTML documents showed that formal scholarly communication trends on the Web were mainly influenced by text URL citations from non-HTML documents.  相似文献

An overview of the benefits and limitations of different types of industrial separation membranes is presented. Their properties strongly influence the choice of methods of manufacture. The choice of membrane composition is also influenced by their role in the total filtration plant, especially by methods of cleaning and flow optimisation. The discussion has been limited to liquid filtration systems and concentrates on microfiltration.  相似文献

This paper attempts to highlight quantitatively and qualitatively the growth and development of world literature on materials science in terms of publication output and citations as per Web of Science (2006–2010). The objective of the study was to perform a scientometric analysis of all materials science research publications in the world. The parameters studied include growth of publications and citations, continent-wise distribution of publications and citations, country-wise distribution of publications, domain-wise distribution of publications and citations, publication efficiency index, distribution of publications and citations according to number of collaborating countries, variation of mean impact factor in materials science domains, identification of highly cited publications and highly preferred journals, quality of research output and application of Bradford’s law.  相似文献

Using 17 fully open access electronic journals published uninterruptedly during 2000–2004 in the field of Library and Information Science the present study investigated the trend of LIS Open Access e-journals’ literature by analysing articles, authors, institutions, countries, subjects, & references. Quantitative content analysis was carried out on the data, data were analysed in order to project literature growth, authorship pattern, gender pattern, cited references pattern and related bibliometric phenomena. The analysis indicates that there were as many as 1636 articles published during 2000–2004 with an average increment of 23.75 articles per year. The authorship pattern indicates that team research has not been very common in LIS OA publishing and male authors were keener than female authors. Authors from academic institutions were paid more interest in OA publishing and most of them were from developed nations. The subject coverage of these OA e-journals was very vast and almost all facets of information and library science were covered in these articles. There were 90.10% of articles of these e-journals contained references and on an average an article contained 24 references. Of these, 38.53% of references were hyperlinked and 87.35% of hyperlinked references were live during investigation. The analysis of data clearly indicates that OA e-journals in LIS are rapidly establishing themselves as a most viable media for scholarly communication.  相似文献
