Since the survey of health sciences libraries by the American Medical Association in 1969, a number of other hospital library surveys have been conducted. Twelve hospital/health sciences library surveys published since the passage of the Medical Library Assistance Act are reviewed. The use of data from these surveys for management and planning is discussed and directions for future library survey development are suggested. 相似文献

This project is addressed to the effectiveness of video mediated instruction on the learning of the tennis service by novices. The research was carried out in an indoor tennis hall under normal training conditions. Three experimental groups were used: a video-model (VMT), a video-feedback (VFT) and a group with a combination of video modelling and video feedback (VMFT). Two control groups - based on different training periods-were also used: a traditional training group (TT1) which practised for a period of 45 min per training session and a second traditional training group (TT2) which practised for a period of only 30 min per training session. All subjects took part in five successive training sessions. No clear advantages of using video mediated instruction methods in teaching novices the tennis service could be demonstrated. Five sessions of 30 min practical training were shown to be as effective as five sessions of 45 min practical training in producing improvements in both form and achievement scores of novice tennis players. While, in the early stages, form and achievement scores were not shown to be significantly related, after five sessions a significant correlation (P less than 0.05) was shown. 相似文献

The valuation of multi-staged pharmaceutical R&D can be interpreted as a chain of real options. In valuing these compound option models, a crucial problem is how to deal with the different types of risk. Previous models, such as Cassimon et al. (2004), offer a closed-form solution for the valuation of a new drug development using a generalized n-fold compound option model, but implicitly bundle both commercial and technical risk in one risk measure. We extend this model by explicitly incorporating technical risk, while still preserving the closed-form solution of the model. As such, this extended model is better suited to handle real-life valuation cases in the pharmaceutical industry. We document the theoretical model with a real-life project of a major pharmaceutical multinational. 相似文献

Municipalities face a dilemma as they pursue technologically enabled modes of providing traditional services. The planning stages of e-government amount to triage: which specific municipal functions and services can a municipality afford to implement (or which services can they afford not to implement) given the costs of technology and technological capability? Little in the way of defining the leading edge of innovation among cities exists. To date, the literature on e-government “best practices” tends to stress creating standards for evaluating web-enabled services rather than for benchmarking the actual status of e-government implementation. In other words, a well-developed literature is emerging around standards by which municipal websites can be evaluated such as navigability and content standards. These standards do not give us insight, however, into the specific functions and services as they emerge on municipality websites. As a means toward addressing this lacuna, the authors created a rubric for benchmarking implementation among cities nationwide using a broad range of functional dimensions and assigning municipalities “e-scores.” In this paper, the authors describe these efforts, their approach and their findings. 相似文献
