This paper examines end-user, online searching using data from a questionnaire mailed to 150 Canadian health professionals in practice settings. The response rate was 83% (n = 124). The data provide a demographic profile of early adopters of end-user searching in the health care community. Positive correlations with the user's level of implementation of end-user searching were found for the following variables: amount of time spent in research activities, amount of system training received, and use of Medical Subject Headings (MeSH). There was a negative association between the amount of time spent in patient care and implementation level. General practitioners and family physicians had lower implementation levels than physicians in other specialties. Successful implementers were more likely to be computer literate and to place a high value on formal information sources such as books, journals, and libraries. Health professionals using so-called "user-friendly" or menu-based software had lower levels of personal commitment to using online databases, as measured by a combination of continuance of use, willingness to pay personally, type of recommendations made to colleagues, and hardware ownership.  相似文献

Virtual and Augmented Realities are advancing technologies that are becoming more popular in gaming and programming communities. However, virtual reality has been in development for decades. As libraries are often at the forefront of offering new and advancing technologies to their communities, virtual and augmented reality programs have become new additions to library services. While gaming is the prominent use of these technologies, virtual and augmented reality affords many educational opportunities. Mississippi State University Libraries have recently added a virtual/augmented reality lab as part of its library program.  相似文献

This study examines our experiences as female junior scholars with multicultural backgrounds teaching at the same Hispanic‐serving institution. As education scholars with mixed‐heritage families, we identify with the commitment to serving Latinos and the number of mixed‐heritage people in the USA. The election of Barack Obama, whose racial background is both black and white, to the US presidency signifies the emergence of mixed‐heritage people as a demographic presence in this country. Our research suggests that more understanding is needed about the experiences of mixed‐heritage faculty in academia, as well as the ways in which faculty from any background may develop multiple affiliations with cultural communities and pursue professional agendas related to communities that they do not neatly fit into. Despite this variation in backgrounds and research agendas, we share our efforts in advancing Latin@ educational attainment.  相似文献

Key points

  • U.S. university OA policies are far less mandatory than those in the U.K.
  • The waiver clauses in U.S. university policies make it easy for authors to decline making their articles OA.
  • The relative autonomy – and competitiveness – of U.S. universities may be the reason for weaker OA policies.
  • OA in the U.S. is likely to be driven by government funding agency policies rather than by academia.
