This study examines how the social sciences' debate between qualitative and quantitative methods is reflected in the citation patterns of sociology journal articles. Citation analysis revealed that quantitative articles were more likely to cite journal articles than monographs, while qualitative articles were more likely to cite monographs than journals. Quantitative articles cited other articles from their own quantitative-dominated journals but virtually excluded citations to articles from qualitative journals, while qualitative articles cited articles from the quantitative-dominated journals as well as their own qualitative-specialized journals. Discussion and conclusions include this study's implications for library collection development.  相似文献

We analyzed serial citations in 72 marine biology master's theses as well as the ranking data of aquatic science serials from six global serial citation metrics, to assess serial use by marine biology graduate students from two perspectives. From 1,035 unique serials, a core of 123 titles was identified and evaluated for access. Citation ages averaged 13.5 years, with 27% of serial citations dated prior to 1996. Students cited serials from disciplines beyond marine biology, demonstrating broad title dispersion compared to several other studies. Recommendations are offered for future investigation to develop a stronger understanding of graduate students’ use of the library's serial collection.  相似文献

This case study is a citation analysis of 56 PhD theses submitted in 2005 at Wuhan University (www.whu.edu.cn) in China. The authors analyzed 10,222 citations in theses in Library and Information Science, Biology, Photogrammetry and Remote Sensing, and Stomatology and reviewed and compared the characteristics of the literature cited in the four disciplines. The results revealed that in Biology and Stomatology mainly English language publications were cited whereas in the field of Library and Information Science, the cited literature came primarily from Chinese sources. In Photogrammetry and Remote Sensing, citations were almost evenly split between English and Chinese sources. An appendix with tables of the journal titles cited most frequently may be used to evaluate serial holdings and to serve as a guide for students preparing their theses. In addition, the implications for library collection development policies and other technical services are discussed.  相似文献

Bibliographic information and cited references from source articles by members of the Emory University Physics Department were downloaded as an ASCII file from ISI's SCISEARCH (Science Citation Index) on DIALOG. This file was loaded into a word processing program for editing and then into a spreadsheet program for analysis. Information about format, subject and location of each cited reference was added to the spreadsheet. Analysis of the citations and added information can be useful in making collection management decisions.  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

The history and development of the Science Citation Index (SCI) is an example of the power of users in defining and influencing the development of a new technology. The SCI was developed as a tool for the historian of science for the purpose of tracing the history of ideas, but it was appropriated by users for purposes for which it was unintended – as a tool for evaluating the literature, individuals, institutions, and countries. The development of a citation tool gave rise to a debate over what is actually measured by citations. The citation‐as‐reward camp views citations as indicators of quality and impact, whereas the citation‐as‐persuasion camp views citations as no more than rhetorical devices. While neither view can fully explain how authors use citations, citation‐as‐reward prevails as the dominant interpretation.  相似文献

The citation analysis literature of the last twenty years is selectively reviewed for papers dealing with citation accuracy, citer motivation and the relationship between citation frequency and library use of materials. Although this relationship is rather complex, the two activity measures are moderately correlated. Citation of an item should promote its use and vice versa. There are some factors, however, which inhibit a very high correlation. Faculty who cite use nonlibrary as well as library materials, and they tend to use scholarly journals which often do not circulate (circulation being one measure of library use). Citations are not simply countable data points; some are more important than others, or differ in purpose. Further, there is a subliterature detailing the degree of inaccuracy among citations. Collectively, these variables tend to dilute the correlation between use of library materials and citation frequency. These limitations notwithstanding, citations represent an auditable trail of scholarship, and citation analysis remains a useful tool for evaluation of library collections and subject literatures.  相似文献

Over the past decade, national research evaluation exercises, traditionally conducted using the peer review method, have begun opening to bibliometric indicators. The citations received by a publication are assumed as proxy for its quality, but they require standardization prior to use in comparative evaluation of organizations or individual scientists: the citation data must be standardized, due to the varying citation behavior across research fields. The objective of this paper is to compare the effectiveness of the different methods of normalizing citations, in order to provide useful indications to research assessment practitioners. Simulating a typical national research assessment exercise, he analysis is conducted for all subject categories in the hard sciences and is based on the Thomson Reuters Science Citation Index-Expanded®. Comparisons show that the citations average is the most effective scaling parameter, when the average is based only on the publications actually cited.  相似文献

学术图书是学者研究成果的集中体现。作者在写作过程中,参考、引证了大量文献,将这些被引文献析出即形成索引。因此,将精选学术图书作为来源文献,创建图书引文数据库是现实可行的。基于这一设想,并付之于实践,即形成了《中文图书引文索引》(CBkCI)。该数据库以精选学术图书作为来源文献(统计源),统计、分析图书作者引用图书、期刊论文、报告等所有文献资料的情况。CBkCI示范数据库的研制成功,不仅填补了国内在图书引文领域的空白,促进学术图书出版质量的提升,而且有助于图书馆进行图书采访,精选馆藏,并为学术评价提供坚实的基础。  相似文献

This study, conducted at the Indiana University School of Dentistry Library using citation analysis, examined graduate dental student theses citations to determine the nature of materials cited, journal ownership, journal citation frequency, and citation age distribution. The results were compared to other scientific discipline citation analyses. Study results indicated that for the period studied, masters dental students, like medical and science students, cited recently published scholarly dental journal literature. The majority of the journals cited were owned by Indiana University system libraries. Areas for further research include faculty resource usage, e-journal impact, and interdisciplinary resource use.  相似文献

Recent advances in methods and techniques enable us to develop interactive overlays to a global map of science based on aggregated citation relations among the 9162 journals contained in the Science Citation Index and Social Science Citation Index 2009. We first discuss the pros and cons of the various options: cited versus citing, multidimensional scaling versus spring-embedded algorithms, VOSViewer versus Gephi, and the various clustering algorithms and similarity criteria. Our approach focuses on the positions of journals in the multidimensional space spanned by the aggregated journal–journal citations. Using VOSViewer for the resulting mapping, a number of choices can be left to the user; we provide default options reflecting our preferences. Some examples are also provided; for example, the potential of using this technique to assess the interdisciplinarity of organizations and/or document sets.  相似文献

The purpose of this research is to investigate the current state and trend of government website information cited by social science and humanities (SS&H) journal articles in China. The Chinese Social Science Citation Index (CSSCI) was used as the benchmark and the Social Science Citation Index (SSCI) journals as the reference samples. It analyzed 204,019 web citations (N = 5,063,237) found in 925,506 articles that were published in CSSCI journals during the 1998–2009 period. The findings unveil that web citations accounted for only 4.03% of the total number of citations (N = 5,063,237), and that citations of Chinese government websites constituted 6.6% of the total number of web citations (N = 204,019). The study disclosed detailed information regarding citations derived from ministries and commissions directly under the State Council websites (N = 69), government online media (N = 7), government website citation subjects (N = 21), and various types of government website information (N = 5). Although government website information has limited influence on SS&H, their impact is currently growing rapidly. In comparison with international research community, influence of government web information on Chinese social science is higher, while its influence on humanities is lower. Essentially, Chinese scholars put emphasis on citing information from authoritative central government websites or highly visible state-owned media information as supporting evidences in their articles. In general, the citation of information from Chinese government website tends to hot social issues of society. Finally, it is necessary to promote the visibility of local government websites, to develop policies and guidelines to encourage the disclosure and the diversity of data, so that there will be more citation balances between social and technological topics.  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
