The literature of medical librarianship of Nigeria is reviewed. The staff structure of Nigerian univeristy libraries and, in particular, of the medical libraries attached to them is restrictive, unprogressive, and unconducive to the development of medical librarianship in Nigeria. These medical libraries should cease to be administered and regarded as just unavoidable appendages of the main university libraries. They should be independent, full-fledged libraries of their own, recognixed as full academic departments of their respective colleges or faculties, with their heads being in no way inferior in status to other heads of academic departments.The granting of faculty status to Nigerian unviersity librarians should go the whole way and let the principle of multiple professorships be applied to the staff structure of unviersity libraries. Efforts are being made to effect bibliographic organization of Nigerian medical literature. A national library of medicine for Nigeria, however, humble its beginning, should be established.  相似文献

This paper describes the procedures used at the Library of the College of Physicians of Philadelphia to divide its ninety-year-old dictionary card catalog. The division was necessitated by overcrowding, obsolete subject headings, and lack of a complete authority list which resulted in like materials being scattered throughout the catalog under several headings. Two catalogs were created: the historical-biographical catalog, representing all works published before 1950 and all works of historical or biographical nature; and the current catalog, containing all works published from 1950 on, excepting historical or biographical materials. The 1950- catalog was further divided into name and subject catalogs, and the subject section was revised according to MeSH. The project was completed in about two years. As a result, searching time has been much reduced, and the library is able to take advantage of the annual revisions of MeSH to update the subject catalog.  相似文献

An ongoing debate regarding the nature of therapeutic communities concerns the extent to which these communities reinforce the ideologies of individualism and community. This article engages this discussion through a process of social text analysis informed by the dialogism theory of Russian philosopher and literary scholar Mikhail Bakhtin. Dialogism seeks to understand the multiple voices interpenetrating particular utterances, revealing an emergent social construction of meaning. Applying this approach to examples of discourse from a prominent therapeutic community, Alcoholics Anonymous, illustrates how meaning in the discourse of this movement can be understood to emerge among the interplay between the ideologies of individualism and community as expressed within the movement's narrative practice.  相似文献

In this essay, we respond to the narratives and essays in this issue by examining organizational power issues related to researchers and institutional research boards (IRBs). Rather than taking a singular perspective on power, we use multiple perspectives and suggest that the cumulative analyses provide the best understanding of IRBs and organizational power.  相似文献

The author, a professor at the University of Toronto, touches briefly on the extensive and rich archival literature that supports the teaching of macroappraisal, but notes that this is not the only educational material she offers her students when teaching appraisal theory. She discusses the usefulness to archivists of literature from the fields of ethnography, organizational knowing, records in history, personal documentary behaviour, memory, and communications, noting that the use of texts from these fields can encourage students to reflect on their own presumptions and to develop a taste for the wide reading and research that must support appraisal.  相似文献

OBJECTIVE: A staff development committee (SDC) was convened to implement staff development opportunities for an academic health sciences library system comprised of three separate facilities. The charge for the SDC was to: (1) develop programs to enhance workplace skills and personal growth, (2) communicate the availability of existing programs at the university and medical center, and (3) encourage the staff to participate in these opportunities. PROGRAM: The committee created goals and objectives and developed a survey designed to give staff the opportunity to provide input for this initiative. With an 80% response rate, the survey results were used to plan 15 events based on staff needs and preferences. First-year attendance for SDC-sponsored events was 459. Committee members served as liaisons for each event. Two forms were developed to facilitate event planning. A monthly announcement sheet, email reminders, and the library's local area network are used to communicate upcoming SDC events and encourage attendance. CONCLUSION: This approach can serve as a useful model for similar program planning in any organization.  相似文献
