This paper discusses concepts and terminology of some aspects of the autoimmune and rheumatic disorders as related to medical reference work. Details of anatomic, biochemical, and pathologic processes are not discussed. Knowledge of the specific terminology involved in this area may help to ensure a good approach to developing prudent strategies for database searching of the medical literature and, therefore, is reviewed. MeSH thesaurus terms are shown and textword synonyms are presented that provide tools for thorough searching techniques. Commonly used medical jargon as well as older terminology for this area is also explained. Examples of specific search strategies are illustrated. 相似文献

Problems in online retrieval of information concerning medical devices are discussed, including background data regarding legislative history and terminology. An analysis of the results of searching on ten sample topics in this subject area provides a framework for approaching such problems. In addition to a consideration of recall, uniqueness, and overlap, other factors influence database selection and order of consultation. Indexing characteristics of selected health science, engineering, business, and regulatory databases play a major role in medical device information provision. 相似文献

This paper provides an overview of the research into current medical vocabularies and their impact on searching the Web for health information. The Web provides growing opportunities for laypersons to gain knowledge about specific health conditions, though research to date has been incomplete. Many studies have examined aspects of controlled medical vocabularies. Other studies have examined aspects of medical Web searching vocabularies. In this context, there is a growing need to examine more closely laypersons' Web queries using controlled medical vocabularies that were designed to serve the needs of medical professionals. It may be the case that the average consumer of Web health services is not able to use correct medical terminology, and may not be able to choose analogous or synonymous terms from a search result list. Our review suggests a growing need for studies to examine the current applicability of controlled medical vocabularies as well as alternatives to semantic query by Web search engine users. 相似文献

Contemporary society and our educational institutions over-emphasize left-brained, analytical skills. This pervasive influence extends even into the library instruction classroom. This article calls for an adjustment of this left-brained paradigm, with a more holistic, right-brained, or “global” instructional approach. Background information is offered on split-brain theory, hemispheric function, and the importance of right-brain teaching techniques. The specific strategies of metaphor, visual thinking, direct experience, and fantasy are discussed with specific examples cited. A mind map, cluster diagram, and literature searching exercise are included. 相似文献

QUESTION: How have theorists and empirical researchers treated the human tendency to avoid discomforting information? DATA SOURCES: A historical review (1890-2004) of theory literature in communication and information studies, coupled with searches of recent studies on uptake of genetic testing and on coping strategies of cancer patients, was performed. STUDY SELECTION: The authors' review of the recent literature included searches of the MEDLINE, PsychInfo, and CINAHL databases between 1992 and summer of 2004 and selective, manual searches of earlier literature. Search strategies included the following subject headings and key words: MeSH headings: Genetic Screening/psychology, Decision Making, Neoplasms/diagnosis/genetics/psychology; CINAHL headings: Genetic Screening, Genetic Counseling, Anxiety, Decision Making, Decision Making/Patient; additional key words: avoidance, worry, monitoring, blunting, cancer. The "Related Articles" function in MEDLINE was used to perform additional "citation pearl" searching. MAIN RESULTS: The assumption that individuals actively seek information underlies much of psychological theory and communication practice, as well as most models of the information-seeking process. However, much research has also noted that sometimes people avoid information, if paying attention to it will cause mental discomfort or dissonance. Cancer information in general and genetic screening for cancer in particular are discussed as examples to illustrate this pattern. CONCLUSION: That some patients avoid knowledge of imminent disease makes avoidance behavior an important area for social and psychological research, particularly with regard to genetic testing. 相似文献

Successful subject searching depends upon the terminology of the search query. This paper compares the terminology of book titles with that of Library of Congress Subject Headings (LCSH) 1 on a semantic level. Methods of ananlyzing titles into title phrases that serve as matching units are described. Guidelines used to choose LCSHs with the closest semantic matches to title phrases are set forth. The pairing of title phrases with semantically related LCSHs constitutes the data of the study. Categories representing the types of semantic relationships holding between pairs of terms are defined. Results of the study show that the most common semantic relationship holding between title phrases and LCSH is a hierarchical one where title phrases are more specific than LCSHs. 相似文献

The experiences of medical students, residents, and faculty with a computerized literature searching system were evaluated. Third-year medical students, internal medicine and family practice residents, and full-time and voluntary faculty at one medical school had the opportunity to use a full-text and bibliographic medical literature retrieval system free of charge for an eleven-month period. Subjects conducted nearly nine thousand literature searches over a period of 942 system hours. Questionnaire data showed that participants could learn to use and would use an electronic information system, felt capable of using the system, utilized the system for a variety of purposes and in a number of different ways, and viewed the system as a valuable tool in searching the medical literature. The results are discussed in the context of the educational needs of the four user-groups and medical education planning by institutions. 相似文献

OBJECTIVE: The article explores the characteristics of public health information needs and the resources available to address those needs that distinguish it as an area of searching requiring particular expertise. METHODS: Public health searching activities from reference questions and literature search requests at a large, urban health department library were reviewed to identify the challenges in finding relevant public health information. RESULTS: The terminology of the information request frequently differed from the vocabularies available in the databases. Searches required the use of multiple databases and/or Web resources with diverse interfaces. Issues of the scope and features of the databases relevant to the search questions were considered. CONCLUSION: Expert searching in public health differs from other types of expert searching in the subject breadth and technical demands of the databases to be searched, the fluidity and lack of standardization of the vocabulary, and the relative scarcity of high-quality investigations at the appropriate level of geographic specificity. Health sciences librarians require a broad exposure to databases, gray literature, and public health terminology to perform as expert searchers in public health. 相似文献

PURPOSE: The paper explores the current state of generalist search education in library schools and considers that foundation in respect to the Medical Library Association's statement on expert searching. SETTING/SUBJECTS: Syllabi from courses with significant searching components were examined from ten of the top library schools, as determined by the U.S. News & World Report rankings. METHODOLOGY: Mixed methods were used, but primarily quantitative bibliometric methods were used. RESULTS: The educational focus in these searching components was on understanding the generalist searching resources and typical users and on performing a reflective search through application of search strategies, controlled vocabulary, and logic appropriate to the search tool. There is a growing emphasis on Web-based search tools and a movement away from traditional set-based searching and toward free-text search strategies. While a core set of authors is used in these courses, no core set of readings is used. DISCUSSION/CONCLUSION: While library schools provide a strong foundation, future medical librarians still need to take courses that introduce them to the resources, settings, and users associated with medical libraries. In addition, as more emphasis is placed on Web-based search tools and free-text searching, instructors of the specialist medical informatics courses will need to focus on teaching traditional search methods appropriate for common tools in the medical domain. 相似文献

A brief review of hospital library reference problems is presented. The essential problem in a one-person medical library is the time factor or time constraint under which appropriate answer to reference questions must be delivered. Various other common reference problems such as emergencies, misunderstood requests, ethical considerations of priorities, and the choice of computerized data base versus manual searching are discussed as they relate to the small medical library. Some reference aids are suggested as they apply to specific problems in cancer chemotherapy, syndrome identification, and adverse effects of drugs. A sampling of quick reference sources is included. 相似文献

Eight years' data have been collected in the operation of learning resource centers (LRCs) for medical and dental students at the Medical College of Virginia Campus, Virginia Commonwealth University. Data present evidence of high utilization of facilities and materials, including the successful use of small group cluster carrels. Management concepts and strategies to account for the data are identified and the LRC profile discussed for an understanding of how the strategies are implemented. These management concepts--responsiveness to students, interaction with faculty, and delivery of coordinated service--are transferable to other institutions and serve as guidlines for efficient management of LRC space, staff, equipment, and acquisition in support of medical and dental school curricula. 相似文献

The internet is an important source of medical knowledge for everyone, from laypeople to medical professionals. We investigate how these two extremes, in terms of user groups, have distinct needs and exhibit significantly different search behaviour. We make use of query logs in order to study various aspects of these two kinds of users. The logs from America Online, Health on the Net, Turning Research Into Practice and American Roentgen Ray Society (ARRS) GoldMiner were divided into three sets: (1) laypeople, (2) medical professionals (such as physicians or nurses) searching for health content and (3) users not seeking health advice. Several analyses are made focusing on discovering how users search and what they are most interested in. One possible outcome of our analysis is a classifier to infer user expertise, which was built. We show the results and analyse the feature set used to infer expertise. We conclude that medical experts are more persistent, interacting more with the search engine. Also, our study reveals that, conversely to what is stated in much of the literature, the main focus of users, both laypeople and professionals, is on disease rather than symptoms. The results of this article, especially through the classifier built, could be used to detect specific user groups and then adapt search results to the user group. 相似文献

This study sought to better understand search performance using an online portal containing a collection of heterogeneous library resources for K-12 students. Search performance is examined in terms of search success, search time, strategy, and effort. This study revealed unsuccessful searches tended to take longer than successful searches; preference of search strategy (searching vs. browsing) did not affect search success outcome; students tended to perform well in tasks for which they were able to use various strategies, and unsuccessful searches tended to use more effort—more mouse clicks, more keystrokes, more queries, more sites visited, and more strategy shifts. Implications of the study are also discussed. 相似文献

Since 1980s the rate of technological change has been phenomenal, creating an impact on the information-seeking behaviors of doctoral students and other researchers. When searching the three fields of Information Technology (IT), Information and Communication Technology (ICT), and Educational Technology (EdTech), it is like opening a Pandora's Box; the variation in terminology is obvious. This makes searching, managing, and evaluating sources in these interdisciplinary fields challenging, and doctoral students trying to classify and analyze technology related studies can easily be overwhelmed. We offer a systematic, practical approach for reviewing and categorizing the literature by providing key search terms, a list of e-Journals, and an organizational structure for naming and framing studies. Doctoral students navigating their way through the literature review may find our resourcesa table-of-contents, an overview of the technology-related literature, and an annotated excerpt of an examined thesis—useful for writing a critical review. 相似文献
