Summary There is no necessary connection between leadership in basic science and leadership in the applications of science, because scientific progress is a cooperative endeavour and not a competitive game; indeed, there may be a conflict between basic research and applied science. The notion of a position of leadership; in science raises questions of what leadership consists in and what its value is to the nation. The two main arguments for government support of science are cultural-social, and economic. The cultural-social argument stresses scientific activity as a form of social consumption of wealth and raises the question of whether other uses of the resources employed would contribute more to the greatness of the society. The economic argument stresses basic scientific research as a form of investment for the future, and raises the questions of what the rate of return on such investment is and whether and to what extent government support is called for. Relevant economic research results bearing on this problem are scarce. Economic theory suggests that competition in the market will supply less than the optimal amount of basic research; but our society substantially supplements the market through private contributions to and government support of science, and the question is whether this supplementation is deficient or excessive. Here difficult problems arise, on which more economic research is needed; one of these concerns the relative merits of government and private support of science. The rule-of-thumb procedures generally recommended for determining the volume and allocation of government support to basic scientific research generally ignore these problems, and amount to endorsing the present level of government support or recommending that it be increased. Allocation of federal support of science should take account of the possibility of stimulating the economic development of poor regions of the country by locating scientific research facilities in them.  相似文献

Clinical medical journals have not been effective in meeting the information needs of practitioners and bridging the gap between clinical research and practice. The slow adoption of results of clinical research is at least partly due to the failure of clinical journals to disseminate information in a way that would motivate practitioners to change practice. Although implementation is primarily a local process, medical journals are in a unique position to advance implementation by modifying their focus and adjusting their contents. Strategies that may be useful include publication of pre‐appraised evidence summaries and ‘clinical bottom‐lines’ and giving importance to systematic reviews and large evaluative research articles as they represent higher levels of evidence and have greater potential to change practice. Clinical journals should encourage researchers to consider how and by whom the findings will be used and provide information on implications for implementation such as possible strategies that may work, cost‐effectiveness, side‐effects and potential barriers to implementation. Medical journal publishers should explore ways to cooperate so that findings of landmark clinical trials could be shared thus reducing the ‘scatter’ of medical information. Electronic media offers numerous advantages such as quick accessibility and linking of information, and medical journals should capitalize on such innovations. There is a paradigm shift in health care practice as evidence is consciously and explicitly incorporated into individual patient care. Medical journals need to change to reflect this change in practice and provide practitioners with valid and relevant information.  相似文献

Empirical data on the development of interaction, communication, and language in deafblind children is very rare. To fill this gap, a case study was conducted in which the interaction between a teacher and a deafblind boy age 3 years 4 months was analyzed. Sequential analysis of their interaction confirmed some general clinical impressions about interaction with deafblind children, and provided the basis for suggestions on how the interaction pattern might be changed.  相似文献

This paper uses Tronto's political ethics of care as a normative framework to evaluate a model of teaching and learning professional development. This framework identifies five integrated moral elements of care – attentiveness, responsibility, competence, responsiveness and trust. This paper explicates on each of these elements to evaluate the piloting and implementation of a teaching and learning professional development model at a South African higher education institution. The political ethics of care was found to be a useful normative framework for a group of higher educators to reflect on the process of engaging in teaching and learning professional development in that it revealed the importance of differential power relations, the importance of working collaboratively and being attentive to the needs of both caregivers and care receivers.  相似文献
