The librarians at four hospital libraries describe the electronic reference service, "Ask A Librarian," offered at their institutions. The hospitals are vastly different in size and in number of library staff, and offer the "Ask A Librarian" service to different clientele. The article illustrates that both large hospitals with a large library staff and small hospitals with a solo librarian and some volunteers can offer this type of service. 相似文献

To determine the nature and extent of the emerging field of “health law” scholarship in China, we retrieved 2956 publications about various aspects of health law published up through 2014 in 268 journals from the “Chinese Social Science Citation Index” and from the list of Chinese “Core Journals” maintained by the Peking University Library. By bibliometric analysis, we observed some interesting results which were different from our expectations. The collaboration network among Chinese health law (CHL) authors was relatively small, loose, unstable and early in its development. Kan Tian and Lixin Yang were leading authors, Renmin University of China was the primary institution, and Beijing was the predominant region studying Chinese health law (CHL). Kan Tian ranked 1st in the collaboration network and Lixin Yang published the most number of articles on CHL. Comprehensive universities made up the majority of institutions studying CHL, while medical colleges did not focus on health law research, possibly due to medical schools focusing mainly on clinical education and not attaching as much importance to social and humanistic aspects of medicine. Food safety, health administration, and the general principles of civil law were the main areas of focus in CHL research, which is basically in line with what we expected. 相似文献

This paper identifies salient practices of faculty mentors of undergraduate research (UR) as indicated in the extensive literature of the past two decades on UR. The well-established benefits for students involved in UR are dependent, first and foremost, on high-quality mentoring. Mentorship is a defining feature of UR. As more and different types of colleges and universities strive to meet student demand for authentic scholarly experiences, it is imperative to identify what effective UR mentors do in order to ensure student engagement, quality enhancement, retention, and degree-completion. We offer an original analysis of the literature on UR mentoring in which we identify 10 significant “lessons learned,” or evidence-based practices of effective UR mentors that apply broadly across disciplines, students, institutions, and mentoring approaches. 相似文献

Peer mentoring programs are an important component in the strategy to enhance the first year undergraduate experience. The
operation of these programs needs to be informed by evidence as to their effectiveness. In this article we report on a six-year
study of the development of a peer mentoring program in which feedback is used to improve program implementation. Evidence
from surveys of participants in the program shows that this process has significantly enhanced their experiences and that
the effects of these benefits have increased throughout the life of the program. Moreover, participation in the program enhanced
the leadership, communication, and organizational skills of the peer mentors. 相似文献
