BACKGROUND: The use of a structured abstract has been recommended in reporting medical literature to quickly convey necessary information to editors and readers. The use of structured abstracts increased during the mid-1990s; however, recent practice has yet to be analyzed. OBJECTIVES: This article explored actual reporting patterns of abstracts recently published in selected medical journals and examined what these journals required of abstracts (structured or otherwise and, if structured, which format). METHODS: The top thirty journals according to impact factors noted in the "Medicine, General and Internal" category of the ISI Journal Citation Reports (2000) were sampled. Articles of original contributions published by each journal in January 2001 were examined. Cluster analysis was performed to classify the patterns of structured abstracts objectively. Journals' instructions to authors for writing an article abstract were also examined. RESULTS: Among 304 original articles that included abstracts, 188 (61.8%) had structured and 116 (38.2%) had unstructured abstracts. One hundred twenty-five (66.5%) of the abstracts used the introduction, methods, results, and discussion (IMRAD) format, and 63 (33.5%) used the 8-heading format proposed by Haynes et al. Twenty-one journals requested structured abstracts in their instructions to authors; 8 journals requested the 8-heading format; and 1 journal requested it only for intervention studies. CONCLUSIONS: Even in recent years, not all abstracts of original articles are structured. The eight-heading format was neither commonly used in actual reporting patterns nor noted in journal instructions to authors.  相似文献

Since its introduction, the Journal Impact Factor has probably been the most extensively adopted bibliometric indicator. Notwithstanding its well-known strengths and limits, it is still widely misused as a tool for evaluation, well beyond the purposes it was intended for. In order to shed further light on its nature, the present work studies how the correlation between the Journal Impact Factor and the (time-weighed) article Mean Received Citations (intended as a measure of journal performance) has evolved through time. It focuses on a sample of hard sciences and social sciences journals from the 1999 to 2010 time period. Correlation coefficients (Pearson's Coefficients as well as Spearman's Coefficients and Kendall's τα) are calculated and then tested against several null hypotheses. The results show that in most cases Journal Impact Factors and their yearly variations do not display a strong correlation with citedness. Differences also exist among scientific areas.  相似文献

This is the first part of a comprehensive, quantitative study of biomedical book reviewing. The data base of the total project was built from statistics taken from all 1970 issues of biomedical journals held in the Science Library of the Massachusetts Institute of Technology. Of 285 so-called "life sciences" journals held by that library, fifty-four English journals (excluding Science and Nature) were found to contain bona fide book reviews (as contrasted with mere author-title lists) and were therefore selected for close study. The statistical results reveal that there were 3,347 reviews of 2,067 biomedical books in these fifty-four selected journals in 1970. Part I of the study identifies key biomedical reviewing journals of quantitative significance. The top ten journals, British Medical Journal, Lancet, Annals of Internal Medicine, Journal of the American Medical Association, Archives of Internal Medicine, New England Journal of Medicine, Quarterly Review of Biology, Bioscience, Canadian Medical Association Journal,(*) and American Journal of the Medical Sciences, accounted for 63.03% of the total number of reviews in 1970.  相似文献

Journal articles are the most common publication format for U.S. academic health sciences librarians. This is consistent with the findings of other researchers. Of the total publications in this study, 68% were in journals. Watson found that 69% of the academic librarians' publications were published in some type of journal [8]. Similarly, Yerkey and Glogowski found that 67% of the publications in their study were journal articles, although their population consisted of all types of authors of library/information science materials [9]. Both the present study and Watson found that monographs were the second most common publication outlet. Watson found that 16% of the total publications were monographs; the current study identified 14.8% of the total publications as monographs [10]. Although Watson's findings are similar to the newer results, it is important to note that Watson's study was conducted in a different manner and included book reviews, which were not counted in the present study. The health sciences librarians in the present study published more than two thirds of their articles in library/information science journals and 27% in health sciences journals. Similarly, in Yerkey and Glogowski's study, the second-largest number of library/information science articles appeared in medical and health sciences journals [11]. Fang also found that 22.57% of the journal articles on health sciences librarianship or by health sciences librarians were in medical journals [12. This seems to demonstrate the desire of health sciences librarians to communicate with the health professionals. Yerkey and Glogowski that library and information science is an interdisciplinary field, "borrowing and supplying information to and from other disciplines"[13].  相似文献

The hospital health sciences library of today that reaches out to the world knowledge base through electronic networks bears little resemblance to its forebears. Yet to understand the challenges and future directions of the hospital library it is necessary to examine how it began and how it has evolved in more than 200 years. This paper identifies five developmental periods in which major strides were made: the colonial years through the 19th century; World War I to the Great Depression; World War II and the 1950s; the 1960s--the Great Society and the Medical Library Assistance Act; and the 1970s, an era of growth for hospital libraries.  相似文献

This paper considers a new model for forming ranked lists of scientific journals on the basis of a bibliometric analysis. The model is based on searching in anabstract database of a set of articles that is semantically equivalent to a set of articles of a user or group of users, for whom a repertoire of scientific periodicals is selected. In other words, a query must result in an assembly of articles with the same thematic orientation, which is expressed in the articles of an author. To achieve this goal, KeyWords Plus were used as a query for articles by workers from three scientific organizations in different scientific fields (biomedical, geological, and physico-mathematical fields). KeyWords Plus, which give a short retelling of each article, are joined in a query into groups, whose number was correspondingly equal to the number of articles of workers from these organizations. The query yielded lists of articles withthe same sequences of keywords, which proved their semantic proximity. Using different filters we analyzed the groups of journals that focused articles that are of interest to us to the greatest extent. The obtained lists were compared with the lists of journals that are most cited by the authors of the articles; the similarity of the lists in the field of natural sciences was ascertained to be significant and the similarity in the field of exact sciences was shown to be less. The possible spheres for the application of the KeyWords Plus method, which is an alternative to an analysis of citations, as well as the applicability of a new model to the Scopus database, where controlled thesauri are used as additional keywords, are described.  相似文献

A system of four research levels, designed to classify scientific journals from most applied to most basic, was introduced by Francis Narin and colleagues in the 1970s. Research levels have been used since that time to characterize research at institutional and departmental levels. Currently, less than half of all articles published are in journals that been classified by research level. There is thus a need for the notion of research level to be extended in a way that all articles can be so classified. This article reports on a new model – trained from title and abstract words and cited references – that classifies individual articles by research level. The model covers all of science, and has been used to classify over 25 million articles from Scopus by research level. The final model and set of classified articles are further characterized.  相似文献

From the 1990s to the early twenty-first century, a range of writers in sociology, history, and cultural studies would increasingly see emotion as an important area of study. This “affective turn” has offered an important corrective to standard scientific conceptions of emotion, highlighting the mysteries of embodiment that are ignored by a narrowly empirical approach. While celebrating this development, this paper offers a series of cautions drawn from a comparative history of scholarly attention to emotion. Similarly to the early twenty-first century understanding of affect, the social sciences of the late nineteenth and early twentieth century employed a neo-romantic conception of emotion. By the 1920s, this idea would be subsumed into a new scientific paradigm that saw the new recording technologies as perfect vehicles for taming the mysteries of emotion. I discuss strategies for avoiding this scientizing of emotion in our own period, which is similarly taken with a series of “new technologies.”  相似文献

OBJECTIVES: This 1990-1991 study explored the relationship between the size of health sciences library journal collections and the number of different journals cited by medical school faculty in departments of biochemistry and medicine. METHODS: Two regression equations, including variables associated with a national stratified sample of 622 faculty who published articles during those two years, were used to explore factors correlated with variations in faculty use of the journal literature and faculty publishing productivity. RESULTS: Results suggest that, after controlling for other variables in the models, neither the number of different journals those faculty cited, nor the number of articles they published, had statistically significant correlations with the number of journals in the health sciences library collection. CONCLUSION: The traditional view that the size of an academic health sciences library's journal collection is a good measure of how well that library is positioned to support faculty research may not be entirely accurate.  相似文献

This article analyzes the knowledge structure of library and information science (LIS) in South Korea based on analysis of the theories presented in scholarly research articles. A content analysis of 654 LIS articles that appeared in two major journals since 1970 revealed overall theory use in LIS, such as growth and distribution of theory use by subfield, origin of theory, degree of theory use, and development of theory. The 654 articles analyzed used about eighty theories. The largest percentage of theories originated in LIS, followed by social science, sciences, and humanities. The degree of theory use indicates 2.10 in the 5 point ratio scale of the “Five Degrees of Theory Use Model.” The proposed theory use model provides an analytical tool to delineate degrees of theory use in LIS. In short, the results of knowledge structure analysis in LIS research show that LIS in South Korea needs much more development in various fields.  相似文献

This paper discusses the results of statistical research on the information massif of the “Abstract Journal” DB (of the Republic of Kazakhstan) with a volume of about 50000 documents, which was carried out based on a number of scientometric indices. The types of journals, thematic structure of the AJ DB and prospective directions for investigations are designated. The leading journals on the themes of the series of the abstract journal are revealed. The averaged ratio between the scientific articles of the Kazakhstan scientists published in Kazakhstan, CIS-countries and far-abroad countries is determined to be 80: 5: 1. The main themes of publications in the English language relate to chemistry, physics, and mathematics. The works in various fields of Kazakhstan science are presented in Russian journals.  相似文献

OBJECTIVE: To quantify the impact of Pakistani Medical Journals using the principles of citation analysis. METHODS: References of articles published in 2006 in three selected Pakistani medical journals were collected and examined. The number of citations for each Pakistani medical journal was totalled. The first ranking of journals was based on the total number of citations; second ranking was based on impact factor 2006 and third ranking was based on the 5-year impact factor. Self-citations were excluded in all the three ratings. RESULTS: A total of 9079 citations in 567 articles were examined. Forty-nine separate Pakistani medical journals were cited. The Journal of the Pakistan Medical Association remains on the top in all three rankings, while Journal of College of Physicians and Surgeons-Pakistan attains second position in the ranking based on the total number of citations. The Pakistan Journal of Medical Sciences moves to second position in the ranking based on the impact factor 2006. The Journal of Ayub Medical College, Abbottabad moves to second position in the ranking based on the 5-year impact factor. CONCLUSION: This study examined the citation pattern of Pakistani medical journals. The impact factor, despite its limitations, is a valid indicator of quality for journals.  相似文献
