Private companies and government agencies are now creating and tapping into vastly more data than ever before. These data flows include enormous amounts of personal information and raise questions about privacy and intellectual policy that could have profound impacts on our lives. While data collection and creation are nearly ubiquitous, the instruments of collection and analysis are often hidden in order to track more natural behavior. Recent revelations of massive governmental data collection offer the country, and librarians in particular, an opportunity to discuss and question the societal implications of “Big Data,” and the policies that govern them. 相似文献

In most current teacher evaluation systems, tests are typically used for all teachers or for none. Peterson describes how three Utah school districts employed tests, specifically National Teachers Examinations, as one line of optional evidence for use along with a selection of other evidence in the promotion of eligible teachers. The author indicates that the optional use of test scores both answers many objections to the testing of veteran teachers and allows the test results of teachers choosing to submit them to inform promotion decisions. 相似文献

AIM: In 2002, a discussion in the United Kingdom (UK) between South-west Information for Clinical Effectiveness (SWICE) librarians and a member of the South Australian Department of Human Services Libraries' Consortium (SAHSLC) raised the possibility of developing an after-hours virtual reference service between the two consortium groups. The aim of the service is to put medical practitioners in contact with a librarian when urgent help is required in finding clinical medical information after hours. METHODS: A trial project has begun and has been given the name 'Chasing the Sun'. The service will make use of time-zone differences between the UK and Australia, so that librarians at work in another country will be able to answer urgent patient-related queries that cannot wait until normal office hours. RESULTS: This paper looks at the development of 'Chasing the Sun' from initial concept, funding proposal and trial project stage to implementation. It includes details of the groundwork, software evaluation, trials, outcomes, cost and benefits, future directions and potential problems yet to be experienced or overcome. CONCLUSION: This service is the first of its kind between health libraries in the world and offers potential for future worldwide expansion. 相似文献
