Electronic reserves: copyright and permissions.
(41/2178)
Electronic reserves present a new service option for libraries to provide needed materials during hours that the library is not open and to user groups located some distance from library collections. Possible changes to current copyright law and publishers permissions policies have delayed the development of electronic reserves in many libraries. This paper reviews the current state of electronic reserves materials in the publishing and library communities and presents the results of a survey of publishers to determine permissions policies for electronic materials. Issues of concern to both libraries and publishers are discussed. (+info)
Reporting of occupational and environmental research: use and misuse of statistical and epidemiological methods.
(42/2178)
OBJECTIVES: To report some of the most serious omissions and errors which may occur in papers submitted to Occupational and Environmental Medicine, and to give guidelines on the essential components that should be included in papers reporting results from studies of occupational and environmental health. METHODS: Since 1994 Occupational and Environmental Medicine has used a panel of medical statisticians to review submitted papers which have a substantial statistical content. Although some studies may have genuine errors in their design, execution, and analysis, many of the problems identified during the reviewing process are due to inadequate and incomplete reporting of essential aspects of a study. This paper outlines some of the most important errors and omissions that may occur. Observational studies are often the preferred choice of design in occupational and environmental medicine. Some of the issues relating to design, execution, and analysis which should be considered when reporting three of the most common observational study designs, cross sectional, case-control, and cohort are described. An illustration of good reporting practice is given for each. Various mathematical modelling techniques are often used in the analysis of these studies, the reporting of which causes a major problem to some authors. Suggestions for the presentation of results from modelling are made. CONCLUSIONS: There is increasing interest in the development and application of formal "good epidemiology practices". These not only consider issues of data quality, study design, and study conduct, but through their structured approach to the documentation of the study procedures, provide the potential for more rigorous reporting of the results in the scientific literature.

Scientific publication productivity of Korean medical colleges: an analysis of 1988-1999 MEDLINE papers.
(43/2178)
To identify where the quality research activity has been and is carried out in Korea, and to examine to what extents Korean medical colleges play leading roles in the production of international research papers, we investigated the publication productivity of Korean medical colleges and their medical departments as measured by the number of papers published in foreign journals indexed in MEDLINE. The 12-year period from 1988 to 1999 is covered. A total of 4,881 papers is published in MEDLINE foreign journals by the researchers in Korean medical colleges during the period. The production of MEDLINE papers are concentrated in a few universities. More than 60% of MEDLINE foreign journal papers is published by top five universities 25% by Seoul National University, and 15% by Yonsei University. The newly established medical colleges at the University of Ulsan and Sungkyunkwan University produced outstanding numbers of papers in less than ten years. Radiology has led the internationalization of Korean medical papers. It was the most productive specialty identified in this study. The productivity of Internal medicine is on the rise from the mid-1 990s, and the field began to produce the most number of papers since then. (+info)
Self-citations in six anaesthesia journals and their significance in determining the impact factor.
(44/2178)
Self-citation of a journal may affect its impact factor. We investigated self-citations in the 1995 and 1996 issues of six anaesthesia journals by calculating the self-citing and self-cited rates for each journal. Self-citing rate relates a journal's self-citations to its total number of references. We defined self-cited rate as the ratio of a journal's self-citations to the number of times it is cited by the six anaesthesia journals. We also correlated self-citing rates with the impact factor of the six journals for 1997. Citations among the six journals differed significantly (P < 0.0001). Anesthesiology had the highest self-citing rate (57%). Anaesthesia, Anesthesia and Analgesia, British Journal of Anaesthesia, Canadian Journal of Anaesthesia and the European Journal of Anaesthesiology had self-citing rates of 28%, 28%, 30%, 11% and 4% respectively. The self-cited rates were 31%, 35%, 34%, 27%, 31% and 17% for Anaesthesia, Anesthesiology, Anesthesia and Analgesia, British Journal of Anaesthesia, Canadian Journal of Anaesthesia and the European Journal of Anaesthesiology, respectively. North America journals cited the North America literature. This also occurred, to a lesser extent, in the European anaesthesia journals. A significant correlation between self-citing rates and impact factors was found (r = 0.899, P = 0.015). A high self-citing rate of a journal may positively affect its impact factor. (+info)
Evaluating "payback" on biomedical research from papers cited in clinical guidelines: applied bibliometric study.
(45/2178)
OBJECTIVES: To develop a methodology for evaluating the impact of research on health care, and to characterise the papers cited on clinical guidelines. DESIGN: The bibliographic details of the papers cited in 15 clinical guidelines, developed in and for the United Kingdom, were collated and analysed with applied bibliometric techniques. RESULTS: The median age of papers cited in clinical guidelines was eight years; most papers were published by authors living in either the United States (36%) or the United Kingdom (25%)-this is two and a half times more than expected as about 10% of all biomedical outputs are published in the United Kingdom; and clinical guidelines do not cite basic research papers. CONCLUSION: Analysis of the evidence base of clinical guidelines may be one way of tracking the flow of knowledge from the laboratory to the clinic. Moreover, such analysis provides a useful, clinically relevant method for evaluating research outcomes and different strategies in research and development. (+info)
Mapping the literature of cytotechnology.
(46/2178)
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. (+info)
Croatian Medical Journal at the turn of the millennium.
(47/2178)
The turn of the millennium coincided with the inclusion of the Croatian Medical Journal into the bibliographic databases MEDLINE (1998), and Current Contents/Clinical Medicine (1999), which greatly increased the number of submitted manuscripts. The increased pressure on the editorial office prompted us to modify the editorial procedure and sharpen our acceptance criteria. At the same time, we extended our author-friendly policy to all for global medicine and (2) medicine in translational and emerging countries. The Editorial Board and the Advisory Board were critical in developing and improving the Journal and setting the highest standards in all aspects of publication, especially in manuscript selection by high-quality peer review. In this editorial, we finally meet the members of the two Boards in person, or rather, in photographs and short biographies. (+info)
