Postgraduate education for medical librarians is approachable from several perspectives, including internships, certificate programs, and continuing education programs. The diverse population of medical library personnel calls for a varied yet coordinated system of postgraduate education involving the Medical Library Association, regional medical libraries, library schools, and the National Library of Medical, in addition to active participation by all librarians in the health sciences field. Basic philosophies for each of the major types of programs are discussed and recommendations for future training of health sciences librarians are provided. 相似文献

Drawing on components of agenda-setting theory and the two-step flow of information from mass media to news audiences, this study examines the effects of mass and interpersonal communication on breast cancer screening practices among college- and middle-aged women (n = 284). We theorized that screening behaviors among younger women would be influenced more by interpersonal sources of information while screening among middle-aged women would be more influenced by exposure to mass-mediated information. Findings supported anticipated patterns, revealing important and varying roles for both mass and interpersonal communication in the health behaviors of women. Implications for health practitioners and campaign planners, as well as recommendations for future research, are discussed. 相似文献

Women in middle management continue to face multiple paradoxes arising from their structural and gendered locations that add to the uncertainty of negotiating organizational life. Investigating the lived experiences of women middle managers can illuminate the constraints and paradoxes endemic to organizing, for such experiences foreground tensions at the intersection of structure, identity, agency, and power. Specifically, this contextual investigation of conversational humor explores links between organizational status, gender, and paradox. In so doing, it demonstrates how women can use humor to negotiate managerial identities and to navigate organizational life. This study uncovers nuanced and important communication tactics of middle management women. This study also reveals the value of investigating the complex convergence of humor, gender, and organizational communication theory. 相似文献

The issue of format duplication in academic library collections is increasingly complicated and perplexing in an environment of static or dwindling resources, soaring user expectations, dynamic access models, and inconsistent and changing publisher and vendor pricing structures. The problem is further complicated for libraries serving a university with multiple campus locations. This paper surveys recent investigative projects and highlights the work of a Duplicate Formats Task Force at Pennsylvania State University charged with determining the extent and nature of format duplication at that institution. 相似文献
