Designing a search strategy to identify and retrieve articles onevidence-based health care using MEDLINE     

Jane Harrison 《Health information and libraries journal》1997,14(1):33-42

Thepractice of evidence-based health care requires that information on methodology be identifiedfrom databases such as MEDLINE. Up until this year there have been no designated medicalsubject headings (MeSH) for evidence-based health care. ‘EVIDENCE-BASEDMEDICINE’ appears as a MeSH term from 1997. The absence of designated MeSH forthis concept prior to 1997 provides a challenge to the searcher. This paper describes the creationof a MEDLINE search strategy to retrieve articles on the methods of evidence-based health carepublished prior to the introduction of the new term, where an optimal combination of free-textand MeSH terms is required to identify relevant material. The study examines both free-text andsubject heading searching and attempts an optimal balance of sensitivity and specificity. It beginsby examining separate free-text and subject heading searches. Sensitivity of the subject headingsearch was 33% and specificity 80%, while the free-text search produced asensitivity of 50% and a specificity of 67%. The final strategy, combining bothapproaches, was more successful with sensitivity reaching between 82 and 90% andspecificity 83%. It is therefore possible to devise a search strategy to retrieve articles on themethods of evidence-based health care with relatively successful rates of sensitivity andspecificity. The limitations of MEDLINE, however, necessitate the use of additional approachesin identifying articles on the methods of evidence-based health care.  相似文献

The terrible gift: Museums and the possibility of hope without consolation     

Roger I. Simon ^{Author Vitae} 《Museum Management and Curatorship》2006,21(3):187-204

Public history is turned toward the future no less than the past. Little discussion exists as to how practices of public history might foster new ways to live with the presence of history. Museum exhibitions are one site where such discussions may take place. Particularly generative in this regard are exhibitions that present artifacts and documentation that reference state-sponsored violence. One such exhibition in development is discussed. While this exhibition presents evidence of past events, it also assembles traces of the past and bequeaths them as a testament, “a terrible gift” that places difficult demands on those to whom it has been given. In discussing the practices of inheritance initiated by such a gift implications are drawn for how museums might initiate a reconsideration of the force of history in social life.  相似文献

What's for Sale at Canadian Universities? A Mixed‐Methods Analysis of Promotional Strategies          下载免费PDF全文

Roger Pizarro Milian 《Higher Education Quarterly》2017,71(1):53-74

The current fiscal environment has driven Canadian universities to become more entrepreneurial, seeking out and competing over new sources of funding. Despite such intensifying competition, little effort has been made to document the promotional tactics that Canadian universities are using to render themselves appealing to external audiences. This study examines the contents of the home pages of English‐speaking universities in Canada. It finds that, though there are some differences in the tactics that primarily undergraduate and research‐intensive universities employ, both generally strive to emulate the same institutional ‘template’. Moreover, the usage of more unorthodox promotional tactics, drawing on labour market rhetoric or discourses of inclusivity, is limited. These findings are theorised in relation to contemporary work within organisational sociology and strategic management.  相似文献
