In order to assess the current status of MEDLINE training provided by schools of library science, a survey was conducted of those schools having an educational identification code issued by the National Library of Medicine. Information was gathered on such variables as the instructors' background and preparation, the course objectives and content, and the amount of on-line experience provided to students in each of eleven programs. An evaluation of these measures indicates that more opportunities to gain experience in using MEDLINE should be initiated by library schools and that current efforts should be continued and expanded. Specific recommendations for accomplishing these goals are outlined; they are addressed to health sciences librarians, library school educators, the Medical Library Association, and the National Library of Medicine. 相似文献

Polyvocal approaches allow researchers and informants to interact on a more equal footing and informants’ voices to be heard in the final text. But research methods intended to empower informants also can be a source of unanticipated authorial power ‐ the power to confront informants with unsolicited self‐reflections and to textualize people's lives and words. The authors reflect on those ethical dilemmas in this article. 相似文献

Increasingly, career centers on university and college campuses are making use of the World Wide Web to help their users with a myriad of career related needs. This technological service delivery mode has many advantages that will be briefly reviewed in this article. As well, a computer emphasis has the potential for drastically changing career centers as we know them: their traffic patterns, staffing needs, resource procurement, and perhaps most importantly, their outcomes in the lives of the students who make use of them. This article discusses these changes and through a review of seven critical issues, challenges the reader to closely examine the implications for technology within their own career centers. 相似文献

The need for those working in a variety of settings to interact effectively with technical experts has grown dramatically in recent years as computers have become essential to the performance of an increasing broad range of professional work. This article presents a case of this sort of interprofessional interaction, exploring the process and outcomes of collaboration between technical professionals and educators working to bring Internet access to an urban public school district. Drawing on field note and interview data, the case reported here illustrates how differences in institutional routines and professional values can generate differing agendas, contrasting assumptions, and contrasting expectations concerning project products and outcomes among collaborators from different professional worlds. In the case we describe, these differences affected such central matters as the types and usefulness of technical resources to which users had access as well as users' confidence in the technology. The case also illustrates how aspects of this interprofessional conflict were addressed through an organizational change. The kinds of issues that arose in this project are likely to occur in a variety of professional settings; therefore, examination of this case provides insight into a variety of issues and dynamics that should be considered when embarking upon or analyzing any interprofessional collaborative effort, and particularly one that involves technical professionals. 相似文献

During the second year of life, babies actively play with sounds they produce. Their sound-play often has musical qualities such as pitch, rhythm, and melodic contour, but it is not the same as singing. Singing is a complex activity, one requiring skills that usually take the entire preschool years to develop.Lyle Davidson is a professor at the New England Conservatory of Music, Boston, MA. W. George Scarlett is a professor of child psychology at Assumption College, Worcester, MA. The research reported on in this article is based on work done at Project Zero, Harvard School of Education, Cambridge, MA.The research reported here was part of a larger study of early symbolization carried out at Project Zero, Harvard School of Education, and funded by the Spencer and Carnegie foundations. The results of this larger study will appear in a formthcoming book,The Making of Meanings, edited by Dennie Wolf and Howard Gardner. 相似文献

Searching for patterns in the MeSH vocabulary 总被引:1,自引:0,他引:1
NLM revises its MeSH vocabulary annually to reflect changes in biomedical literature and the health sciences community. This study tested two hypotheses about NLM's MeSH vocabulary. The first is that new terms are added to MeSH when their broader terms have an increased number of postings. One examination compared the number of postings for the broader terms of new and existing terms in the current MEDLINE file; the other compared them over time. No significant statistical difference was found in either case. A second hypothesis--that there is a relationship between the patterns of MEDLINE indexing and searching and the organization of the MeSH tree structure--was tested by comparing the distribution of searched terms in the MeSH trees with the distribution of all terms. It was found that certain trees are searched more often than could be predicted by the overall term distribution, while others are searched less frequently than expected. In summary, (1) new terms cannot be predicted by the increase in postings of existing terms, and (2) searchers' and indexers' use of the terms' tree structure does not correlate with the terms' distribution in the MeSH trees. 相似文献
