Increases in price during the last twenty years were studied for the journals listed in the 1983 Brandon list, and during the last fifteen years for all medical journals and for U.S. periodicals overall. When compared with increases in the Consumer Price Index (CPI), prices in all three categories of publications have increased much more rapidly than have prices overall. Libraries whose journal-acquisition budgets increased merely at the same rate as the CPI during the periods examined today can purchase only 50% to 70% of the journals they purchased in 1963. This information should help librarians justify budget increases. 相似文献

In recent years most marriage and family journals have expanded their coverage to include research and information on mental health, ethnic groups, sexuality, women, rape, family violence, and the elderly. Given the increasing number of such periodicals, it has become more and more important that behavioral and social sciences librarians develop some familiarity with the literature in this growing field. The following subject review lists fifty publications in the area, including professional journals, lay magazines, newsletters, and abstracting and review journals. 相似文献

Diagnostic medical sonography has been evolving as a recognized allied health occupation since the early 1970s, but no bibliometric studies of the literature of the field have been published. This study, part of the Medical Library Association Nursing and Allied Health Resources Section's Project for Mapping the Literature of Allied Health, attempted to identify the core journals in diagnostic medical sonography and determine how well these journals are indexed by MEDLINE, EMBASE/Excerpta Medica, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL). Citation analysis was done using the three journals listed for the field by the Brandon/Hill list. Characteristics of two of these three journals affected the results to the extent that more data should be gathered to reach conclusions about the literature of diagnostic medical sonography as a whole. Results of the analysis do suggest that the literature of echocardiography, which is a special area of diagnostic medical sonography, is indexed much more completely by MEDLINE and EMBASE/Excerpta Medica than by CINAHL. Suggestions are made for librarians making collection development decisions in this area of allied health. 相似文献

This paper provides information on a research project undertaken at the University of Arkansas in Fayetteville to study publications by the campus researchers with an emphasis on the STEM (agricultural sciences, physical science, biological sciences, engineering and mathematics, etc.) disciplines at the macro level for a 3-year period. The overall objective of the study was to provide evidence-based data of periodical use to assist with collection decisions and to identify collection strengths at the university level. We used the Web of Knowledge database (Science Citation Index, Social Science Citation Index, and Arts and Humanities Citation Index) to identify the periodical literature in which our researchers published and those that they cite in their publications. We also determined the extent to which our researchers are publishing in and citing periodicals from the Elsevier, Wiley, and IEEE journal packages. A methodology for extracting citations from Web of Knowledge into an Excel spreadsheet is also provided. 相似文献

This study considered health coverage in 3 highly circulated U.S. feminist magazines: Ms., Bitch, and Bust. The authors used critical discourse analysis to examine 80 print and online articles for representations of liberal, social, radical, and postfeminist feminist ideologies in health coverage; the rhetorical strategies publications used for health content and how they compare with mainstream women’s magazines; and their emphasis on health policy and public health initiatives. The findings suggested that the magazines relied on discursive approaches resembling those of mainstream magazines when covering health, such as prioritizing personal health issues and individualized responses. However, through distinctive feminist lenses, they also performed better than mainstream women’s magazines in presenting health issues, representing a broader range of concerns affecting women, addressing people from diverse communities, and suggesting opportunities for collective response. 相似文献

The health information needs of health care professionals and consumers in less-developed countries, although somewhat similar to those of their U.S. counterparts, have a number of unique differences. Health care professionals in developing countries are more diverse in their backgrounds, training, experience, and work settings. These differences, combined with cultural variables, a lack of resources and trained information professionals, contribute to the complexity of health information delivery. Consumers in developing countries, due to a lower literacy rate and a higher rate of commercial health information, face different problems when attempting to make health-related decisions. 相似文献

This study demonstrates the growth of medical periodical literature by means of the increase of titles indexed in the Index-Catalogue and in Index Medicus, with reference to other biomedical-related titles not covered in these publications. Stress is laid on the fact that information outside the biomedical area is needed by the researcher. Problems of information retrieval, with the specific needs of the user in mind, are discussed, together with the particular problems of indexing which this specificity raises. 相似文献

Comparison of bibliographic databases for information on the rehabilitation of people with severe mental illness 总被引：1，自引：0，他引：1
OBJECTIVE: The research sought to examine the overlap in coverage between several health-related databases, thus enabling the identification of the most important sources for searching for information on the rehabilitation of people with severe mental illness. METHODS: The literature was searched within a systematic review. Several health-related databases were retrieved (Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, MEDLINE, PsycLIT, Sociofile, and Social Science Citation Index), noting their source and comparing results retrieved from each database. FINDINGS: The total number of studies retrieved from each database varied. Almost a third of the papers retrieved from each database were unique to that source. Forty-two percent of the papers were only found in one database. Restricting a search to one database alone would miss many papers and could affect the results of a systematic review. PsycLIT was the most useful database for this topic area, containing 44% of the papers. MEDLINE, the database of first choice for many health professionals, held only 29%. CONCLUSIONS: No database was determined to be significantly more useful than any other--each warranted inclusion in the study. Reliance cannot be placed on one database alone, and other methods such as hand searching should also be used. Although this may not be new information for information professionals, it is likely to be new for health professionals and researchers who are increasingly performing their own literature searches. Information professionals have an important role to play in conveying this message to those outside their profession. 相似文献

Recent federal legislation mandates integration of disabled Americans into the mainstream of our society. Consequently, there is a need for more information about physically disabled persons. Librarians and other professionals must acquire a realistic understanding of the perspectives and concerns of people with disabilitites. This understanding is best gained from contact with the disabled themselves. While extensive personal contact with the disabled is not possible for many people, they can acquire this understanding by reading the periodical literature published for (and often by) disabled persons. These periodicals serve several important functions for disabled consumers, and their emphases have changed as the information demands of the disabled have evolved over the years. To librarians and other professionals, these periodicals offer information not found elsewhere about publications and services for the disabled. More importantly, they can educate librarians, rehabilitation professionals, and the general public about the needs and abilities of those Americans who are physically disabled. 相似文献

Eating disorders affect millions of people, and their prevalence demonstrates that the condition exists across gender and cultural boundaries. The Internet is a major channel for publishing and disseminating electronic information, allowing worldwide access of massive health-related, lay- and professional-oriented information. However, much research has found that health-related information on the Internet can be overwhelming, incomplete, and/or inaccurate. The success of health promotion in the 21st century depends on whether available consumer health information (CHI) is adequate, accurate, and easy to use. Usually, health disclaimers, caveats, and other health-related alerts are messages to notify users that the information provided is not intended nor implied to be a replacement or an alternative for professional health-related advice. These messages also serve as indicators to show that information providers take ethical responsibility for quality control in terms of providing valid and reliable consumer health information on the Internet. The study used content analysis1to examine the provision and assess the quality of health disclaimers, caveats, and other health-related alerts included in adult CHI on eating disorders published on the Internet in 1998. The researcher-generated instrument was based on evaluative criteria derived from Alexander and Tate;2Health On the Net Foundation;3Mitretek Systems;4and Silberg, Lundberg and Musacchio.5Web search engines (Northern Light, HotBot, and Excite) were used for data collection on Internet-based publications. The results indicated that the CHI on eating disorders on the Internet did not include disclaimers, caveats, and other health-related alerts which demonstrates a lack of quality control and ethical responsibility on the part of the information providers and site administrators. 相似文献

A systematic empirical comparison of different approaches for normalizing citation impact indicators
We address the question how citation-based bibliometric indicators can best be normalized to ensure fair comparisons between publications from different scientific fields and different years. In a systematic large-scale empirical analysis, we compare a traditional normalization approach based on a field classification system with three source normalization approaches. We pay special attention to the selection of the publications included in the analysis. Publications in national scientific journals, popular scientific magazines, and trade magazines are not included. Unlike earlier studies, we use algorithmically constructed classification systems to evaluate the different normalization approaches. Our analysis shows that a source normalization approach based on the recently introduced idea of fractional citation counting does not perform well. Two other source normalization approaches generally outperform the classification-system-based normalization approach that we study. Our analysis therefore offers considerable support for the use of source-normalized bibliometric indicators. 相似文献
