Objective: To determine whether information retrieval might be enhanced by making each component of a structured abstract a separately searchable field. Design: Parallel searches on records arranged so that each abstract could either be searched in its entirety or as a collection of structured fields. Subjects: Records about cardiovascular disease downloaded from MEDLINE and tested against clinical questions derived from a concurrent survey of CD-ROM use in three health science libraries. Intervention: The investigators identified terms used to structure abstracts on MEDLINE and imported the abstracts into an Idealist database prior to searching using keywords from clinical questions. Measurements and main results: recall and precision rates are given for each question in the ‘structured’ and the ‘unstructured’ set of records. Conclusions: Use of structured, rather than unstructured, abstracts improves precision at the ex-pense of recall and places heavier demands upon the searcher’s skill in choosing the correct fields within the abstract to search. Further investigation requires more accurate simulation of MEDLINE software that utilizes features such as MeSH terms, explode, facilities and delimiters.  相似文献

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

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
