The Alfred Taubman Medical Library at the University of Michigan has offered instruction in online literature searching to third-year pharmacy students as a component of the course "Drug Information and Scientific Literature Evaluation" since 1983. In the spring of 1989, a follow-up study was conducted to assess the impact of instruction on four classes of graduates. Of a pool of 151 graduates, 90 (60%) responded to a mailed questionnaire on their use of information and computerized literature searching. The respondents were divided into four subgroups: end-user searchers, users of intermediaries, end users who used intermediaries, and those who did not use computerized literature search systems. Seventy-two percent of the respondents used some type of computerized literature searching, and 42% performed their own searches. The four subgroups differed in general computer use, familiarity with MEDLINE search terminology, information use, reasons for using or not using literature searching, and characteristics of searches (i.e., type, time frame, amount, and frequency). Training in end-user search systems appears to have had an impact on the continued use of computerized literature searching several years after the formal educational program. 相似文献

This exploratory study addresses the ability of values advocacy messages to influence target publics' behavior beyond consumer purchase decisions. In doing so, it fills a gap in the research by extending our understanding of the persuasive premises of values advocacy messages beyond rhetorical (de)construction; consumer behavior; and the establishment of typologies, definitions, and methods of inquiry. Using focus group methodology, target audience members (n=37) of a contemporary values advocacy campaign reflect upon the messages presented in the context of jury deliberations. The findings show that focus group participants would likely reduce punitive damage judgments if exposed to values advocacy messages. The social and cultural implications exposed by participants' comments reflect ongoing concern among critical scholars about the ability of corporations to manipulate public behavior and indicate the ethical conundrum between corporate and community speech. 相似文献

Today more than half of all radio listening in the UK is occurring through digital platforms. Within this context the BBC’s current arts proposition provides a valuable insight into how public service broadcasters are adapting and responding to this burgeoning digital audience. In particular, attention is drawn to the ways in which digital platforms are used to supplement and enhance the auditory listening experience. In doing so, the present article argues that radio continues to occupy a significant position in furthering public engagement with the arts due to, rather than despite of, advances in digital technology. 相似文献
