The social composition of an unselected sample of 282 English children and adolescents aged eight to 16 years involved in intensive training in four sports, football, swimming, tennis and gymnastics, was investigated. Working class children and children from lone parent families were under-represented in all sports. The costs of participation in intensive training were determined, and it was concluded that financial considerations as well as difficulties of access to training facilities were major deterrents to participation by disadvantaged children. Over a period of a two year follow up, working class children were more likely to withdraw from intensive training than middle class children. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

There is an extensive body of research on the determinants of disaster preparedness at the individual and household levels. The same cannot be said for the organizational level. Hence, the purpose of this study is to shed light on the predictors of organizational preparedness for natural disasters. Since leaders of organizations have an incentive to overstate their level of preparedness and because surveys of organizational leaders suffer from selection bias and low response rates, we take the novel approach of interviewing employees about the organizations that employ them. Using an online survey, we collected information from a national sample of 2,008 U.S. employees and estimated the predictors of preparedness at the organizational level. We find, among other results, that organization size (facility level) is a consistent predictor of preparedness at the organizational level. We conclude with policy recommendations and outline an agenda for future research on organizational preparedness for natural disasters.  相似文献

E-mail: s.a.webb{at}sussex.ac.uk Summary This article argues that in a complex socio-political world,social work ethics needs to re-cast the moral identity of thesocial worker in terms of virtue ethics. We review virtue theory'sAristotelian foundations and criticisms of Kantian and utilitariantheory and show how they apply to social work. Subsequentlywe offer an account of a virtue-based social work that questionsthe validity of several models of practice currently fashionable.Virtue theory emphasizes the priority of the individual moralagent who has acquired virtues commensurate with the pursuitof a revisable conception of the good life—the well-beingof all in a defined community. The virtues are the acquiredinner qualities of humans—character—the possessionof which, if applied in due measure, will typically contributeto the realization of the good life or ‘eudaimonia’.The role of the virtuous social worker is shown to be one thatnecessitates appropriate application of intellectual and practicalvirtues such as justice, reflection, perception, judgement,bravery, prudence, liberality and temperance. This ‘self-flourishing’worker, in bringing together the capacity for theoretical andpractical action makes possible a hermeneutic or interpretivepraxis best appraised in dialogue with fellow-practitionersand clients. With a social work remit increasingly routinizedby accountability, quality control and risk management thereis an emphasis on regulation and duties. This has produced aculture of following approved or typical processes resultingin defensive forms of social work wholly uncongenial to thedevelopment of human qualities likely to promote social workers'engagement in critique and revision of what counts as best practice.In sum, our core proposition is that social work practice andeducation, to fit an unpredictable, non-linear world, shoulddevelop means by which professionals nurture the virtues. Thiswould reflexively enhance social work itself.  相似文献

Five-Hundred Life-Saving Interventions and Their Cost-Effectiveness   总被引:42,自引:0,他引:42  
We gathered information on the cost-effectiveness of life-saving interventions in the United States from publicly available economic analyses. "Life-saving interventions" were defined as any behavioral and/or technological strategy that reduces the probability of premature death among a specified target population. We defined cost-effectiveness as the net resource costs of an intervention per year of life saved. To improve the comparability of cost-effectiveness ratios arrived at with diverse methods, we established fixed definitional goals and revised published estimates, when necessary and feasible, to meet these goals. The 587 interventions identified ranged from those that save more resources than they cost, to those costing more than 10 billion dollars per year of life saved. Overall, the median intervention costs $42,000 per life-year saved. The median medical intervention costs $19,000/life-year; injury reduction $48,000/life-year; and toxin control $2,800,000/life-year. Cost/life-year ratios and bibliographic references for more than 500 life-saving interventions are provided.  相似文献

A Simulated Annealing Approach to Communication Network Design   总被引:1,自引:0,他引:1  
This paper explores the use of the meta-heuristic search algorithm Simulated Annealing for solving a minimum cost network synthesis problem. This problem is a common one in the design of telecommunication networks. The formulation we use models a number of practical problems with hop-limit, degree and capacity constraints. Emphasis is placed on a new approach that uses a knapsack polytope to select amongst a number of pre-computed traffic routes in order to synthesise the network. The advantage of this approach is that a subset of the best routes can be used instead of the whole set, thereby making the process of designing large networks practicable. Using simulated annealing, we solve moderately large networks (up to 30 nodes) efficiently.  相似文献

While there is broad consensus that involving children in research is critically important for understanding their lives, there is considerable caution around their participation in social research on ‘sensitive’ issues. Such caution is further amplified by a lack of agreement about what constitutes a ‘sensitive topic’. This article draws on data from interviews with a range of Australian stakeholders, including children, parents, researchers, ethics committee members, government and non-government organisation representatives, and other decision-makers, specifically related to the question of ‘what is a sensitive topic?’. While participants identified a range of sensitive topics, findings point to sensitivities being closely linked with the contexts of children’s lives and experiences. This requires researchers to approach research in ways that reflect more nuanced understandings of these sensitivities, help address potential concerns and facilitate the development of research relationships that promote ethical conduct of research with children.  相似文献

It has long been recognised that deaf people experience barriers to political participation and that notions of citizenship do not take into account the needs of deaf sign language users. In light of an effort at the European level to increase the potential for deaf sign language users to participate in political processes through technology, this paper provides results from a survey study of deaf sign language users across Europe as to their preferences in using Telecommunications Relay Services (TRS), whether they would like to see the establishment of a pan-European multilingual TRS and if they would make use of such a service for the purposes of political participation. Responses from 74 deaf people across 14 European member states confirm that deaf people want to see such a service, and would be willing to use it in order to make contact with European institutions. Therefore, the establishment of such a service has the potential to contribute to improved access to, and increased willingness to engage in, democracy through telecommunications and thus enhance the citizenship status of deaf Europeans, and therefore enhance their political participation and access to information and communication in society.  相似文献
