This is the third installment in Robert Berring's autobiography, The Education of a Twentieth Century Law Librarian. The first installment is at 32 Legal Reference Services Quarterly 1 (2013). The end of the traditional world of law libraries is chronicled through a study of the workings of the Harvard Law Library in the period 1978-1981. Computerized catalogs, changing styles of reference and difficult questions of management are explored. The painful transition that faced all libraries is discussed. This is the third installment of a five part series on the profound change in law libraries during this period. 相似文献

The topic of childhood vaccinations has received much news media attention recently, prompting scholars to examine how the public has responded. In light of this news, and the deep divide that seems to exist between parents who support childhood vaccinations and those who do not, this study examines how and why individuals may involve themselves in communication about vaccinations, particularly on social media or in other online environments. Focusing on the concept of communicative action and drawing from spiral of silence and other research, a survey of mothers (N = 455) found that those who do not support childhood vaccinations are more likely to engage in communication about the issue, including information seeking, attending, forefending, permitting, forwarding, and sharing. In addition, issue importance and affective and cognitive involvement help drive communicative action regarding childhood vaccinations, which could affect public opinion or public perceptions of the issue. Theoretical and practical implications are discussed. 相似文献

What conservation strategies can be used for Tino Sehgal's 2005 work This Is So Contemporary, and what are their relations to oral traditions? Sehgal's art leaves no material traces, as the artist resists the use of photos and videos acting as a documentary surrogate for his work. This paper will explore how Sehgal's non-written documentation strategies connect to the work of Yumutjin Wunungmurra, a contemporary artist and ceremonial leader from Northeast Arnhem Land, Australia. The connection will be tracked through the role of caretaker and custodian that features in the workflow of both artists. The paper asks whether the performance-based strategies discussed can support the notion of conservation as a social process with multiple stakeholders. 相似文献
