Mapping the literature of occupational therapy.

Occupational therapy, formally organized in the United States in 1917, is considered an allied health field. Mapping occupational therapy literature is part of a bibliometric project of the Medical Library Association's Nursing and Allied Health Resources Section's project for mapping the literature of allied health. Three core journals were selected from the years 1995 and 1996 and a determination was made of the extent to which the cited journal references were covered by standard indexing sources. Using Bradford's Law of Scattering three zones were created, each containing approximately one-third of the cited journal references. The results showed that three journals made up the first zone, 117 journals the second, and 657 the third. The most cited journal was the American Journal of Occupational Therapy. In the second zone, journals from twelve disciplines were identified. While MEDLINE provided the best overall indexing, the Cumulative Index to Nursing and Allied Health Literature (CINAHL) was the only database that indexed the three most cited journals plus nine of the currently active titles in occupational therapy. MEDLINE could improve its coverage of occupational therapy by indexing the journals of the British, Canadian, and Australian national associations.     

How accurate are cited references in Iranian peer‐reviewed journals?

The references cited in scientific articles are as important as any other part of the paper, because of their usefulness to the scientific community and to abstracting and indexing services and citation databases. I studied inaccuracies in references and in‐text citations in sample of 97 of the 519 peer‐reviewed journals accredited by the Iranian National Commission for Journal Accreditation Policy (Ministry of Research, Science and Technology). The target journals published 2,980 articles with 74,577 cited references and 108,151 in‐text citations. The results showed 36.6% as the average percentage error rate (range 5.6% to 61.3%). The mean number of errors in cited reference and in‐text citations was 2.7 per article, and the mean number of errors per journal was 690. For the entire sample of articles, 4,369 in‐text citations did not match any source in the list of references (4%), and 8,683 cited references did not match any in‐text citation (11.6%). The stakeholders in scholarly communication, especially authors, pay insufficient attention to the accuracy of bibliographic references. Peer‐reviewed journals should encourage the use of standardized journal policies and quality‐control measures regarding peer review, data quality and accuracy.     

Mapping the literature of hospital pharmacy

Objectives

This study describes the literature of hospital pharmacy and identifies the journals most commonly cited by authors in the field, the publication types most frequently cited, the age of citations, and the indexing access to core journals. The study also looks at differing citation practices between journals with a wide audience compared to a national journal with a focus on regional issues and trends in the field.

Method

Cited references from five discipline-specific source journals were collected and analyzed for publication type and age. Two sets were created for comparison. Bradford''s Law of Scattering was applied to both sets to determine the most frequently cited journals.

Results

Three-quarters of all cited items were published within the last 10 years (71%), and journal articles were the most heavily cited publication type (n=65,760, 87%). Citation analysis revealed 26 journal titles in Zone 1, 177 journal titles in Zone 2, and the remaining were scattered across 3,886 titles. Analysis of a national journal revealed Zone 1 comprised 9 titles. Comparison of the 2 sets revealed that Zone 1 titles overlapped, with the exception of 2 titles that were geographically focused in the national title.

Conclusion

Hospital pharmacy literature draws heavily from its own discipline-specific sources but equally from core general and specialty medical journals. Indexing of cited journals is complete in PubMed and EMBASE but lacking in International Pharmaceutical Abstracts. Gray literature is a significant information source in the field.     

World biomedical journals, 1951-60: a study of the relative significance of 1,388 titles indexed in Current List of Medical Literature

This study is an application of the relationship of serial articles published to serial articles cited, developed in theory in the author's "Statistical Bibliography in the Health Sciences" (Bulletin 50: 450-461, July 1962). A ranked list of the indexes of significance of most of the serials indexed in Current List of Medical Literature was derived and erected from 21,000 citations secured in a random sampling of 1962 and 1961 biomedical journals regularly received in the Yale Medical Library. The author measures the gross indexing effectiveness of Current List against his indexes of significance, offers his method and results as means to reach objective standards for indexing and abstracting, and projects his results as measures of general value of the serials analyzed.

Searching the right database. A comparison of four databases for psychiatry journals

Journal coverage is one factor that affects the retrieval of relevant information from bibliographic databases. The aims of this study were to investigate the coverage of databases for psychiatry journals, and to assess the overlap between databases. Psychiatry journals were identified using Ulrich’s International Periodicals Directory and then analysed to see which bibliographic databases indexed the most journals. A total of 213 abstracting and indexing services were listed as indexing at least one of the 977 psychiatry journals identified. The four most frequently cited databases (PsycLIT, EMBASE, BIOSIS and MEDLINE) indexed 506 (52%) of the psychiatry journals. Of these 506 journals, PsycLIT indexed 367 (73%), EMBASE 337 (67%), BIOSIS 243 (48%) and MEDLINE 236 (47%). Combining the databases with the highest yields (PsycLIT and EMBASE) increased the number of journals indexed to 461 (91%). The four databases combined accounted for 90% of all psychiatry journals found to be indexed by at least one abstracting and indexing service. More than 400 journals were not indexed at all. Variations in the overlap between PsycLIT, EMBASE, BIOSIS and MEDLINE, and the high proportion (35%) of journals indexed in only one of these four databases emphasize the importance of searching more than one or even two databases to ensure optimal coverage of the literature.     

Mapping the literature of dental hygiene.

Despite the long history of the dental hygiene profession, little research has been conducted on the characteristics of its literature. In this study, the bibliometric method was used to identify the core journals in the discipline and the extent of indexing of these journals. The study was a part of the Medical Library Association (MLA) Nursing and Allied Health Resources Section's project to map the allied health literature. Five journals were found to provide one-third of all references studied. Forty-two journals yielded an additional one-third of the references. MEDLINE had the best indexing coverage with 87% of the journals receiving indexing for at least one-half of the articles included. Limited coverage was provided by EMBASE/Excerpta Medica (11%) and the Cumulative Index to Nursing and Allied Health Literature (9%). The findings identified titles that should be added by indexing services as well as those that should have more complete coverage.

Summary

ScienceDirect? has been developed by Elsevier Science to provide a databased, Web host environment for its journals and those of other participating publishers. The target is to create an integrated environment, which will permit efficient and transparent access to the scientific literature by integrating abstracting and indexing searching and by linking to other publishers' sites.     

Mapping the journal publishing landscape: how much do we know?

In debates about journals, their publishers and the future of both, it is important to be clear about what we are discussing. In this article, the sparse existing literature is surveyed, and original sources examined to provide further detail. The membership lists of six leading publishing associations, and the websites of their members, were also studied. More than half of all peer‐reviewed journals in Ulrich's are published by or on behalf of/in association with nonprofit organizations. Other than the top few commercial publishers, there is little difference in size between the two types; the ‘long tail’ of publishers are small and therefore vulnerable, and yet most are not represented by any trade association. The majority of journals come from the USA or the UK. Nonprofits launch fewer new journals, but are also less likely to close journals. The quality advantage of nonprofit journals may be reducing, but nonprofit journals still predominate among the most highly cited journals.     

Mapping the literature of cytotechnology

The major purpose of this study was to identify and assess indexing coverage of core journals in cytotechnology. It was part of a larger project sponsored by the Nursing and Allied Health Resources Section of the Medical Library Association to map the literature of allied health. Three representative journals in cytotechnology were selected and subjected to citation analysis to determine what journals, other publication types, and years were cited and how often. Bradford's Law of Scattering was applied to the resulting list of cited journals to identify core titles in the discipline, and five indexes were searched to assess coverage of these core titles. Results indicated that the cytotechnology journal literature had a small core but wide dispersion: one third of the 21,021 journal citations appeared in only 3 titles; another third appeared in an additional 26 titles; the remaining third were scattered in 1,069 different titles. Science Citation Index Expanded rated highest in indexing coverage of the core titles, followed by MEDLINE, EMBASE/Excerpta Medica, HealthSTAR, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The study's results also showed that journals were the predominantly cited format and that citing authors relied strongly on more recent literature.     

Literature searching for social science systematic reviews: consideration of a range of search techniques

Background: Literature for a systematic review on the student experience of e‐learning is located across a range of subject areas including health, education, social science, library and information science. Objectives: To assess the merits and shortcomings of using different search techniques in retrieval of evidence in the social science literature. Methods: A conventional subject search was undertaken as the principal method of identifying the literature for the review. Four supplementary search methods were used including citation searching, reference list checking, contact with experts and pearl growing. Results: The conventional subject search identified 30 of 41 included references; retrieved from 10 different databases. References were missed by this method and a further 11 references were identified via citation searching, reference list checking and contact with experts. Pearl growing was suspended as the nominated pearls were dispersed across numerous databases, with no single database indexing more than four pearls. Conclusions: Searching within the social sciences literature requires careful consideration. Conventional subject searching identified the majority of references, but additional search techniques were essential and located further high quality references.     

How much effort is needed to keep up with the literature relevant for primary care?

OBJECTIVES: Medicine must keep current with the research literature, and keeping current requires continuously updating the clinical knowledge base (i.e., references that provide answers to clinical questions). The authors estimated the volume of medical literature potentially relevant to primary care published in a month and the time required for physicians trained in medical epidemiology to evaluate it for updating a clinical knowledge base. METHODS: We included journals listed in five primary care journal review services (ACP Journal Club, DynaMed, Evidence-Based Practice, Journal Watch, and QuickScan Reviews). Finding little overlap, we added the 2001 "Brandon/Hill Selected List of Print Books and Journals for the Small Medical Library." We counted articles (including letters, editorials, and other commentaries) published in March 2002, using bibliographic software where possible and hand counting when necessary. For journals not published in March 2002, we reviewed the nearest issue. Five primary care physicians independently evaluated fifty randomly selected articles and timed the process. RESULTS: The combined list contained 341 currently active journals with 8,265 articles. Adjusting for publication frequency, we estimate 7,287 articles are published monthly in this set of journals. Physicians trained in epidemiology would take an estimated 627.5 hours per month to evaluate these articles. CONCLUSIONS: To provide practicing clinicians with the best current evidence, more comprehensive and systematic literature surveillance efforts are needed.

The medical information needs of internists and pediatricians at an academic medical center

Medical information needs were examined in a survey of sixty-seven physicians selected from the faculty and housestaff at Johns Hopkins Hospital. A standardized questionnaire was administered personally by a medical informatics physician to collect data on information needs, attitudes, and previous experience with computers. The types of information most frequently required by both faculty and housestaff were treatment recommendations and differential diagnosis. The sources of reference information most commonly used were textbooks and colleagues. The information needs of housestaff differed significantly in several categories from those of faculty physicians. Housestaff more frequently needed information for patient care (P less than 0.05), and preferred the use of textbooks (P less than 0.01) and handbooks (P less than 0.001) as information sources. Faculty more frequently needed information for activities unrelated to patient care (P less than 0.01) and placed greater importance on basic science information (P less than 0.01). When asked to suggest references for online access, the respondents named 143 journals and textbooks, with journals overwhelmingly preferred over textbooks. Only one reference, the New England Journal of Medicine, was requested by a majority of the respondents. The importance of a broad understanding of physician information needs through improved data-collection techniques is discussed as a means of increasing the use of medical information systems.     

由Web of Science数据库分析高影响力中华医学会系列期刊引发的思考

通过Web of Science数据库的“被引参考文献检索”途径,将中华医学会123种非SCI期刊作为国内大量的非SCI科技期刊的代表,统计其刊载文献被SCI期刊引用的情况;以被引文献数量大于50篇作为高影响力期刊的筛选条件,分析其中高影响力期刊的被引文献数量、单篇被引文献最高引用频次、施引文献数量、施引文献最高被引频次以及施引文献的国家地区分布、出版年份分布,从而了解这些非SCI科技期刊的国际影响力.基于这一分析,认为SCI期刊并非是获得同行认可的唯一途径,国内大量的非SCI科技期刊应走“立足国内,面向世界”的发展道路,以踏实做专业领域内有影响力的期刊为目标;同时呼吁国家有关部门能对现行科研评价指标进行调整,鼓励质量上乘的稿件能选择具有影响力的国内期刊发表.     

Cultural Pluralism and Ethnic Diversity

Scholars who published articles in five major ethnic studies journals (Canadian Ethnic Studies, Ethnic Forum, International Migration Review, Journal of American Ethnic History, and Journal of Ethnic Studies) were surveyed in order to: (1) provide a profile of scholars in this cross-disciplinary field; (2) discover the kids of information they use for their research; and (3) how they retrieve information for their use. Findings indicate that respondents are a male dominated group, the majority of whom hold a PhD degree in the social sciences and are affiliated with public universities in the U.S. The primary focus of their research is on individual ethnic groups, immigration, demography, cultural diversity and race relations, and various specific aspects of ethnicity, e.g., ethnic literature and ethnic press. Many findings of the INFROSS and other earlier studies were confirmed and are still valued. For example, ethnic studies scholars use many primary sources and rely heavily on identifying information sources form citations in publications they read. They also identify information through contacts with colleagues and other experts, as well as by attending professional conferences. Although they are fairly systematic in their information seeking behavior through the use of abstracting and indexing services, they tend to use these services in the traditional print, as opposed to electronic, formats.
