In recent years, electronic journals are in common use in scholarly communication and we can interpret this situation in various ways. On the one hand, we can say that scholarly communication is now much dependent on electronic resources. On the other hand, it would be too simplistic to say that scholarly communication is now greatly dependent on electronic resources because researchers seldom use other electronic resources. The purpose of this article is to show the position of electronic journals in scholarly communication based on Japanese researchers’ information behavior and estimation. The main focus is on distinguishing the function of scholarly journal and the electronic form. A questionnaire was sent to 1427 physicists, 1026 chemists and 1276 pathologists in universities and other research institutes all over Japan, of whom 775 (54.3%), 494 (48.1%) and 541 (42.4%), respectively, supplied answers. The main results are as follows. Japanese researchers in STM fields use electronic journals as a matter of course, and other electronic resources to some extent, for accessing information; but this shift to electronic resources seemed to be not a transformation but a modification of traditional patterns of use. Researchers still rely on traditional scholarly journals for accessing information and publication, although their recognition has begun to change.  相似文献

A self-consistent methodology is developed for determining citation based influence measures for scientific journals, subfields and fields. Starting with the cross citing matrix between journals or between aggregates of journals, an eigenvalue problem is formulated leading to a size independent influence weight for each journal or aggregate. Two other measures, the influence per publication and the total influence are then defined. Hierarchical influence diagrams and numerical data are presented to display journal interrelationships for journals within the subfields of physics. A wide range in influence is found between the most influential and least influential or peripheral journals.  相似文献

A new economic model for the analysis of scholarly publishing – journal publishing in particular – is proposed that draws on club theory. The standard approach builds on market failure in the private production (by research scholars) of a public good (new scholarly knowledge). In this model, publishing is communication, as the dissemination of information. But a club model views publishing differently: namely as group formation, where members form groups in order to confer externalities on each other, subject to congestion. A journal is a self-constituted group, endeavouring to create new knowledge. In this sense, a journal is a club. The knowledge club model of a journal seeks to balance the positive externalities of a shared resource (readers, citations, referees) against the negative externalities of crowding (decreased prospect of publishing in that journal). A new economic model of a journal as a knowledge club is elaborated. We suggest some consequences for the management of journals and financial models that might be developed to support them.  相似文献

This article reveals different patterns of scholarly communication in the XML research field on the Web and in print journals in terms of author visibility, and challenges the common practice of exclusively using the ISI’s databases to obtain citation counts as scientific performance indicators. Results from this study demonstrate both the importance and the feasibility of the use of multiple citation data sources in citation analysis studies of scholarly communication, and provide evidence for a developing “two tier” scholarly communication system.  相似文献

Previous studies have repeatedly demonstrated that the relevance of a citing document is related to the number of times with which the source document is cited. Despite the ease with which electronic documents would permit the incorporation of this information into citation-based document search and retrieval systems, the possibilities of repeated citations remain untapped. Part of this under-utilization may be due to the fact that very little is known regarding the pattern of repeated citations in scholarly literature or how this pattern may vary as a function of journal, academic discipline or self-citation. The current research addresses these unanswered questions in order to facilitate the future incorporation of repeated citation information into document search and retrieval systems. Using data mining of electronic texts, the citation characteristics of nine different journals, covering the three different academic fields (economics, computing, and medicine & biology), were characterized. It was found that the frequency (f) with which a reference is cited N or more times within a document is consistent across the sampled journals and academic fields. Self-citation causes an increase in frequency, and this effect becomes more pronounced for large N. The objectivity, automatability, and insensitivity of repeated citations to journal and discipline, present powerful opportunities for improving citation-based document search.  相似文献

In earlier papers the authors focused on differences in the ageing of journal literature in science and the social sciences. It was shown that for several fields and topics bibliometric standard indicators based on journal articles need to be modified in order to provide valid results. In fields where monographs, books or reports are important means of scientific information, standard models of scientific communication are not reflected by journal literature alone. To identify fields where the role of non-serial literature is considerable or critical in terms of bibliometric standard methods, the totality of the bibliographic citations indexed in the 1993 annual cumulation of the SCI and SSCI databases, have been processed. The analysis is based on three indicators, the percentage of references to serials, the mean references age, and the mean reference rate. Applications of these measures at different levels of aggregation (i.e., to journals in selected science and social science fields) lead to the following conclusions. 1. The percentage of references to serials proved to be a sensitive measure to characterise typical differences in the communication behaviour between the sciences and the social sciences. 2. However, there is an overlap zone which includes fields like mathematics, technology oriented science, and some social science areas. 3. In certain social sciences part of the information seems even to be originated in non-scientific sources: references to non-serials do not always represent monographs, pre-prints or reports. Consequently, the model of information transfer from scientific literature to scientific (journal) literature assumed by standard bibliometrics requires substantial revision before valid results can be expected through its application to social science areas.  相似文献

This paper deals with information needs, seeking, searching, and uses within scholarly communities by introducing theory from the field of science and technology studies. In particular it contributes to the domain-analytic approach in information science by showing that Whitley’s theory of ‘mutual dependence’ and ‘task uncertainty’ can be used as an explanatory framework in understanding similarity and difference in information practices across intellectual fields. Based on qualitative case studies of three specialist scholarly communities across the physical sciences, applied sciences, social sciences and arts and humanities, this paper extends Whitley’s theory into the realm of information communication technologies. The paper adopts a holistic approach to information practices by recognising the interrelationship between the traditions of informal and formal scientific communication and how it shapes digital outcomes across intellectual fields. The findings show that communities inhabiting fields with a high degree of ‘mutual dependence’ coupled with a low degree of ‘task uncertainty’ are adept at coordinating and controlling channels of communication and will readily co-produce field-based digital information resources, whereas communities that inhabit fields characterised by the opposite cultural configuration, a low degree of ‘mutual dependence’ coupled with a high degree of ‘task uncertainty’, are less successful in commanding control over channels of communication and are less concerned with co-producing field-based digital resources and integrating them into their epistemic and social structures. These findings have implications for the culturally sensitive development and provision of academic digital resources such as digital libraries and web-based subject portals.  相似文献

期刊影响因子的学科差异、领域差异以及绩效考核   总被引:5,自引:1,他引:4       下载免费PDF全文
通过对JCR各学科5459种期刊的被引用指标进行统计学分析,发现不同学科之间存在显著差异,同学科内不同领域之间的期刊也存在显著差异。因此,在涉及到使用影响因子的时候,用影响因子的绝对值对不同学科/领域的期刊进行比较是不合适的。对科研人员的考核而言,用所谓的前15%或30%来进行考核也不合适,因为不同领域JCR收录的期刊数不一样,这种差异是基于SCI数据库的结构,不是出于学科在科学上的重要性。这对于被SCI收录数量少的领域的科学家是不公平的。因此,建议使用影响因子的相对值进行绩效考核,即对影响影子先进行标准化处理,方法是将目标期刊的影响因子除以该领域期刊影响因子的平均值,得到相对值,使不同学科、同一学科不同领域的期刊具有可比性。  相似文献

The paper reports on some of the results of a research project into how changes in digital behaviour and services impacts on concepts of trust and authority held by researchers in the sciences and social sciences in the UK and the USA. Interviews were used in conjunction with a group of focus groups to establish the form and topic of questions put to a larger international sample in an online questionnaire. The results of these 87 interviews were analysed to determine whether or not attitudes have indeed changed in terms of sources of information used, citation behaviour in choosing references, and in dissemination practices. It was found that there was marked continuity in attitudes though an increased emphasis on personal judgement over established and new metrics. Journals (or books in some disciplines) were more highly respected than other sources and still the vehicle for formal scholarly communication. The interviews confirmed that though an open access model did not in most cases lead to mistrust of a journal, a substantial number of researchers were worried about the approaches from what are called predatory OA journals. Established researchers did not on the whole use social media in their professional lives but a question about outreach revealed that it was recognised as effective in reaching a wider audience. There was a remarkable similarity in practice across research attitudes in all the disciplines covered and in both the countries where interviews were held.  相似文献

The emergence of social media has fundamentally changed the way of scholarly communication and allows for scientific research to be shared at an unprecedented speed and scale. While many studies have discussed what papers attract most online attention, how they prevail online is unclear. In this paper, we explore the diffusion patterns of ~170,000 papers with different journal tiers from 2012 to 2019 based on over 3 million Twitter mentions. We first categorize journals by the elite (the top of Q1) and non-elite (Q2~Q4) according to their journal impact factor quartiles, then use network analysis and time series analysis to characterize papers’ dynamic diffusion process, and finally discuss papers’ engaged users and disciplinary contexts. Results show that though elite journal papers spread significantly faster and more broadly than non-elite, some non-elite journal papers reached a sizable audience. For non-elite journal papers, a decent size of social media reach can be achieved through the aid of highly influential users or multiple waves of small spread that span a long period. As a result, popular non-elite journal papers tend to be more viral than the elite, focusing discussions around topics close to daily life. This study provides a new perspective to characterize the diffusion process of scientific papers and helps to further enhance the understanding of such a process.  相似文献

The Web is revolutionizing the entire scholarly communication process and changing the way that researchers exchange information. In this paper, we analyze two views of information production and use in computer-related research based on citation analysis of PDF and Postcript formatted publications on the Web using autonomous citation indexing (ACI), and a parallel citation analysis of the journal literature indexed by the Institute for Scientific Information (ISI) in SCISEARCH. Our goal is to establish a baseline profile of computer science “literature” as it appears in the published journals and as it appears on the publicly available Web. From this starting point, we hope to identify additional research areas dealing with information dissemination and citation practices in computer science and the utility of autonomous citation indexing on the Web as an adjunct to commercial indexing  相似文献
