Librarians continually integrate new technologies into library services for health sciences students. Recently published data are lacking about student ownership of technological devices, awareness of new technologies, and interest in using devices and technologies to interact with the library. A survey was implemented at seven health sciences libraries to help answer these questions. Results show that librarian assumptions about awareness of technologies are not supported, and student interest in using new technologies to interact with the library varies widely. Collecting this evidence provides useful information for successfully integrating technologies into library services. 相似文献

The study of aging can bridge divisions between biology, social sciences, and humanities, develop an understanding of causal interrelationships, and help in distinguishing between fact and opinion. An introductory course in gerontology should, therefore, be firmly tied to the liberal arts core of higher education, and not merely provide an assembly line of facts. Why particular problems have been investigated is as worthy of discussion as the findings themselves. The practical implications of research deserve emphasis, but the aim of university education is not to train pressure groups. Undergraduates should be helped to appreciate difficulties in designing and interpreting gerontological studies, as well as to realize that they are not yet ready to undertake independent empirical investigations. The work of the first author is supported by the Canadian National Research Council (APA 89) and the Department of National Health and Welfare. 相似文献

Professional guidelines state that higher-order thinking skills are a desirable outcome of pharmacy education. In this context, courses in pharmaceutics at the University of Southern California are taught in a learner-centered manner that requires use of chemical reference sources and interpretation of physicochemical information for drug molecules. To facilitate these activities, a librarian worked with faculty to design a class on reference sources and primary literature. Students believed the librarian instruction was beneficial. After the intervention, faculty fielded fewer information-related questions and the librarian received more sophisticated questions. The class emphasizes the importance of collaboration between librarians and faculty in achieving these results. 相似文献

PharmGuide <http://goo.gl/f14Me>is an annotated directory of high quality, freely available, online drug information resources intended for use by librarians, pharmacists, and the public. Given the plethora of drug information websites with varying levels of authoritativeness and accuracy, PharmGuide is intended to facilitate the search for resources by providing links to only those sources that have been critically appraised and that meet specific quality criteria. Methods used in developing the site, evidence of its utility based on usage statistics, and examples of its application in practice are presented within the context of the drug information landscape. 相似文献

Governments aim to mitigate natural hazards' impacts through a disaster early warning system. Drawing on citizen co-production theory and resilient information infrastructures framework, we empirically examined government use of Twitter Tsunami Early Warning Civic Network and citizens' roles in co-providing timely and actionable information. The Indonesian government issued its tsunami early warning Tweet, which was “re-tweeted” without delay by its followers to their own followers to warn tsunami hazards during the 2012 earthquake. Within 15 min it reached over 4 million Twitter users. Based on our case study and social network analysis of Twitter information flows and exchanges within the network, we found that the speed and enormous reach of the government's Twitter tsunami early warnings would be significantly less without citizens' direct participation in re-tweeting, hence influencing greater control of the network. We present evidence for net-savvy citizens' co-production effects on increased government efficiency in providing time-critical public information services. 相似文献

Our aims were to improve our understanding of human performance before 1850 and to put nineteenth- and twentieth-century performances into a broader historical context. Consequently, 536 foot-races performed in Britain in the 'long' eighteenth century were identified, 53 of which were analysed in detail. The best performances at the end of the eighteenth century were compared with those at the end of the nineteenth and twentieth centuries. The data for the nineteenth century were marginally better than those for the eighteenth century up to 20 km, but beyond that Thomas Carlisle's time, set in about 1740, of 2 hours for 21 miles was outstanding. Current records are shown to be better than earlier records at all distances from 5 km up to the marathon, the superiority being most pronounced from 15 km upwards. 相似文献

Using mathematical analysis, we examined the three baton exchanges that occur during a 4×100 m relay. Identical representative 100 m running performances were assumed for each of four elite male athletes, and the calculations were made for optimal or near-optimal positions of the baton exchanges and starting positions of the athletes running the second, third and fourth legs as determined by Ward-Smith and Radford (2002). In this paper, we focus on the calculation of the checkmark position and demonstrate the complexity of the baton exchange process. The results of the mathematical analysis show that, for optimal performance, the checkmark should be located differently for each of the three exchanges in a single race, and is further affected by lane draw and free distance (the distance between the runners at the baton exchange). For a representative free distance of 1 m at each exchange, the checkmark distance ranges from a minimum of 11.04 m at the third exchange in Lane 1 to 12.20 m for the first exchange in Lane 8. Failure by teams and their coaches to consider adequately the complexities of the baton exchanges may help explain why 25.5% of teams in recent World Championships were disqualified or did not finish. 相似文献

Science curricula and teaching methods vary greatly, depending in part on which facets of science are emphasized, e.g., core disciplinary ideas or science practices and process skills, and perspectives differ considerably on desirable pedagogies. Given the multi-faceted nature of science and the variety of teaching methods found in practice, it is no simple task to determine what teaching approaches might be most effective and for what purposes. Research into relative efficacy faces considerable challenges, with confounding factors, ambiguities, conflations, and lack of controls being threats to validity. We provide a conceptual framework characterizing the many teaching strategies found in practice as being variants of two fundamental contrasting epistemic modes, and we disentangle conflations of terms and confusions of constructs in both teaching practice and research. Instructional units for two science topics were developed in parallel in the alternative epistemic modes, differing in concept learning paths but otherwise equivalent. We conducted a randomized controlled study of the comparative efficacy of the two modes for learning core disciplinary ideas, using operationally defined active-direct and guided-inquiry teaching methods. Five middle school teachers taught each unit in both modes over 4 years of classroom trials in an 8-day summer program for eighth grade students. Student understanding of core ideas was assessed using pre- and post-tests, and learning gains were analyzed by mode, teacher, topic, and trial year. Although routes to concept understanding were very different in the two modes, eventual student learning gains were similar, within statistical variation. Efficacy variations between and within teachers were greater than between modes, indicating the importance of teacher effects on student achievement. Findings suggest that teachers need not be bound to one mode throughout and can flexibly decide on the pedagogical approach for each concept and situation, on several grounds other than efficacy of core content acquisition alone. 相似文献
