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

The Ranking Web of World Repositories () is introduced. The objective is to promote Open access initiatives (OAI) supporting the use of repositories for scientific evaluation purposes. A set of metrics based on web presence, impact and usage is discussed. The Ranking is built on indicators obtained from web search engines following a model close to the Impact Factor one. The activity accounts for a 50% of the index, including number of pages, pdf files and items in Google Scholar database, while the visibility takes into account the external inlinks received by the repository (the other 50%). The Ranking provides the Top 300 repositories from a total of 592 worldwide, with a strong presence of US, German and British institutional repositories and the leadership of the large subject repositories. Results suggest the need to take into consideration other file formats and the usage information, an option is not feasible today.  相似文献

A complex structure measure for social groups was applied to the structure of citations in a journal. The citation structure reflected LOTKA's law on the various levels of group structure measure. On the first structure level the reciprocal effect of social and cognitive factors became discernible. The different hierarchical levels of the structure measure were a reflection of the logarithm of number of publications per author obtained in a group of authors with a definite number of publications.  相似文献

A complex structure measure for social groups was established with a view to reflecting the degree of interaction within a social group. The quantitative degrees of relationship between two group members each and their distributions within the group are considered. These distributions can be characterized quantitatively on different hierarchical levels to which a specific meaning can be attributed. The complex structure measure is a combination of measures for the different hierarchical levels. A stratification of scientists based on the number of publications in a journal is reflected in the results obtained by the complex structure measure. Specific information is provided both by the complex structure measure and by the measure on different levels.  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

Two types of series of h-indices for journals published in the field of Horticulture during the period 1998–2007 are calculated. Type I h-indices are based on yearly data, while type II h-indices use cumulative data. These h-indices are also considered in a form normalised with respect to the number of published articles. It is observed that type I h-indices, normalised or not, decrease linearly over a period of ten years. The type II series, however, is not linear in nature: it exhibits partly a concave shape. This proves that the journals (in Horticulture) do not exhibit a linear increase in h-index as argued by Hirsch in the case of life-time achievements of scientists. In the second part of the paper, an attempt is made to study the relative visibility of a journal and its change over time, based on h-indices of journals. It is shown that:
–  the h-index over the complete period 1998–2007 of the journal Theoretical & Applied Genetics (h = 62) is much higher than that of all other journals in the field
–  the relation between the number of publications and the type II h-index for the whole period is not an exact power law (as it would have to be if the Egghe-Rousseau model were applicable)
–  in order to study the dynamic aspects of journal visibility, a field-relative normalised h-ratio is defined to monitor systematic changes in the field of Horticulture. Except for two journals, the Pearson correlation coefficient for yearly values of this field-relative normalised h-ratio indicates that there is no systematic change of the performance of the journals with respect to the field as a whole.

By tracing the flows of patent citation to prior patents and scientific journal articles, we investigate the sources of knowledge for innovation output in Singapore, a small, highly open economy that has traditionally been significantly dependent on foreign multinational corporations (MNCs). We found that the local production of new knowledge by indigenous Singaporean firms depends disproportionately on technological knowledge produced by MNCs with operational presence in Singapore and scientific knowledge generated by foreign universities. Locally produced new knowledge by indigenous firms and local universities/ public research institutes constitutes an as yet insignificant, albeit growing, source for innovation in Singapore.  相似文献
