Objective:We sought to determine how many abstracts presented at the 2012 and 2014 Medical Library Association (MLA) annual conferences were later published as full-text journal articles and which features of the abstract and first author influence the likelihood of future publication. To do so, we replicated a previous study on MLA conference abstracts presented in 2002 and 2003. The secondary objective was to compare the publication rates between the prior and current study.Methods:Presentations and posters delivered at the 2012 and 2014 MLA meetings were coded to identify factors associated with publication. Postconference publication of abstracts as journal articles was determined using a literature search and survey sent to first authors. Chi-squared tests were used to assess differences in the publication rate, and logistic regression was used to assess the influence of abstract factors on publication.Results:The combined publication rate for the 2012 and 2014 meetings was 21.8% (137/628 abstracts), which is a statistically significant decrease compared to the previously reported rate for 2002 and 2003 (27.6%, 122/442 abstracts). The odds that an abstract would later be published as a journal article increased if the abstract was multi-institutional or if it was research, specifically surveys or mixed methods research.Conclusions:The lower publication rate of MLA conference abstracts may be due to an increased number of program or nonresearch abstracts that were accepted or a more competitive peer review process for journals. MLA could increase the publication rate by encouraging and enabling multi-institutional research projects among its members. 相似文献

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

The purpose of this research was to determine the proportion of abstracts in pharmacy journals that are prepared according to the CONsolidated Standards Of Reporting Trials (CONSORT) criteria for abstracts. Certain abstracts for randomized controlled clinical trials (RCTs) indexed in PubMed were eligible for inclusion, with the primary endpoint being median overall compliance to CONSORT recommendations for abstracts. A total of 63 RCT abstracts were included in the analysis, with only 56% of the recommended CONSORT items represented in the sample. It is recommended that pharmacy journals encourage authors to follow CONSORT recommendations for abstracts when submitting RCTs for publication. 相似文献

《The Reference Librarian》2013,54(22):297-308
Reference librarians, who are thoroughly familiar with the purpose, scope and arrangement of abstract journals, are uniquely qualified for the task of writing abstracts. The procedures described here offer a relatively simply way for them to write acceptable abstracts from the outset. Although research is being conducted in the area of machine generated abstracts, there will continue to be arole for human abstractors, who must determine what combination of the author's original words and/or paraphrasing best conveys the central message of the article. The completed abstract must be accurate and must include those terms and phrases that will both facilitate manual indexing and enhance free-text searching of on-line abstracts. 相似文献

The paper articulates the problems of journal publication in a relatively small country such as Romania where locally (i.e. nationally) published journals include most of the national medical scientific output. The starting point was a study ordered by the Cluj University of Medicine and Pharmacy Scientific Council, for the purpose of obtaining an objectively ranked list of all current Romanian biomedical journals that could be used in the evaluation of the scientific activity of the university academic staff. Sixty‐five current biomedical journals were identified—of which more than half were new titles that had appeared over the past 5 years. None of these are included in the Science Citation Index or Journal Citation Reports (JCR). A set of criteria was used for ranking the journals: peer review, inclusion in international databases, publication time lag, language of articles and abstracts, journal specific index and domestic impact factor. The period covered, along with tools and formulas used are presented. The problems of Romanian biomedical journals as well as ways of improving publishing standards are discussed. Also emphasized is the necessity for increased awareness in the medical scholarly community and the role of the library in this respect. 相似文献

We explore the feasibility of automatically identifying sentences in different MEDLINE abstracts that are related in meaning.
We compared traditional vector space models with machine learning methods for detecting relatedness, and found that machine
learning was superior. The Huber method, a variant of Support Vector Machines which minimizes the modified Huber loss function,
achieves 73% precision when the score cutoff is set high enough to identify about one related sentence per abstract on average.
We illustrate how an abstract viewed in PubMed might be modified to present the related sentences found in other abstracts
by this automatic procedure. 相似文献

This study describes a content analysis aimed at identifying the distribution of empirical research strategies and techniques reported in high-profile LIS journal literature published in 2005. For each article, researchers identified the overall research strategy, the data collection technique, and whether the type of analysis was quantitative or qualitative. The taxonomies used in the analysis were those based on Järvelin and Vakkari's [Järvelin, K., & Vakkari, P. (1990). Content analysis of research articles in library and information science. Library & Information Science Research, 12, 395-422] study in order to compare the results with the earlier findings derived from the 1975 and 1985 literature. The survey approach remains the predominant research strategy in both library science and information science. However, there was a marked increase in experimentation. There were more modest increases in the use of qualitative approaches, except for historical research, which showed a marked decline. This study's findings will inform development of methods courses in doctoral programs, which aim to cover the most commonly used strategies and techniques in contemporary LIS research. Revised taxonomies, which include previously unspecified strategies and techniques such as ethnography and transaction log analysis, are suggested for future content analyses of LIS research. 相似文献

Objective: To determine whether information retrieval might be enhanced by making each component of a structured abstract a separately searchable field. Design: Parallel searches on records arranged so that each abstract could either be searched in its entirety or as a collection of structured fields. Subjects: Records about cardiovascular disease downloaded from MEDLINE and tested against clinical questions derived from a concurrent survey of CD-ROM use in three health science libraries. Intervention: The investigators identified terms used to structure abstracts on MEDLINE and imported the abstracts into an Idealist database prior to searching using keywords from clinical questions. Measurements and main results: recall and precision rates are given for each question in the ‘structured’ and the ‘unstructured’ set of records. Conclusions: Use of structured, rather than unstructured, abstracts improves precision at the ex-pense of recall and places heavier demands upon the searcher’s skill in choosing the correct fields within the abstract to search. Further investigation requires more accurate simulation of MEDLINE software that utilizes features such as MeSH terms, explode, facilities and delimiters. 相似文献

An experimental computer-based bibliographic retrieval system has been implemented to explore how semantic (conceptual) relationships between MeSH terms might assist the retrieval process. To construct the experimental system's database, lists of abstracts were produced using MEDLINE. Each list contained papers discussing a specified pair of terms. Each abstract was then analyzed to determine the specific relationship(s) between the two terms discussed in that paper. The project then explored how these semantic relationships could be incorporated into the computer to enhance bibliographic retrieval. 相似文献

This study reports a content analysis of the frequency distribution of diversity-related research in four high-impact Library and Information Science (LIS) journals published between 1995 and 2014. High-impact journals (with high rankings and impact factors) were chosen because empirically based articles from them are more likely to be able to influence future research direction. The journals chosen were published articles quarterly or bi-monthly, with an average of 5–6 articles per issue. A total of 1766 research articles were collected, with 28.71% determined to be related to diversity. Results show an increasing interest in diversity-related research in the LIS field, with a dramatic increase between 2010 and 2014. The majority of diversity-related research focuses on age, gender and ethnicity. Only a small portion of research discusses issues concerning specific populations and emphasizes diversity-related theoretical concepts. More efforts are needed to highlight the link in order to contribute to the diversity and inclusion agenda in LIS. 相似文献

Web-available information resources continue to diversify and proliferate; new segments of the population join the Internet; and technological capabilities of the Web expand. One arena in which these changes are being manifested is in federal statistical information dissemination. Statistical abstracts, a dominant form of information dissemination, are being reshaped in the face of these changes. In this study, a panel of experts from criminal justice and cognate fields participated in a four-round Delphi study to develop a mission statement for the next five years for one statistical abstract, Sourcebook of Criminal Justice Statistics [Pastore, A. L., & Maguire, K. (Eds.). (2001). Sourcebook of criminal justice statistics. Retrieved January 28, 2004, from http://www.albany.edu/sourcebook/]1, and a list of associated requirements for attaining that mission. Participants see the role of statistical abstracts as continuing to be important in demonstrating the range of available statistical information and providing easy access to the most commonly used statistics. Their utility can be enhanced by technological advances. The findings have implications for the role of statistical abstracts in general. 相似文献
