This paper describes the theoretical foundations, empirical findings, and practical and philosophical implications of the Boston Area Diary Study (BADS), a study of the caring behavior of 44 participants over one calendar year. In particular, the paper presents an identification theory of care and discusses how it shaped the conceptualization, collection, and analysis of the data in a year-long diary study of daily voluntary assistance. The findings from the BADS (1) theoretically confirm the identification theory of care; (2) methodologically capture how individuals perceive and carry out caring behavior as a unity; and (3rpar; empirically document the existence of a moral citizenship in America that is substantially more vigorous than is implied by the usual indicators of civic and political citizenship. 相似文献

Summary An increase in fish mortality due to fishing can theoretically change the growth and reproduction of fish populations from
the viewpoint of adaptation. We address the issue of how an iteroparous fish should convert surplus energy into somatic growth
and reproduction at each age under given conditions of mortality. A model of life history, which maximizes the net reproductive
rate using the discrete maximum principle, is improved employing a new relationship between body weight and surplus energy
which we have recently proposed. The model is applied to the North Sea plaicePleuronectes platessa, for which it has been reported that the average length of young fish had increased whereas that of old ones had decreased
for some decades. Although the model cannot directly explain the former phenomenon, the two phenomena can be interpreted as
a change in the optimal life history due mainly to an increase in mortality. 相似文献

The importance of client beliefs in career counseling depends on their ability to add unique information about the client over and above that contributed by aptitudes and interests. The Career Beliefs Inventory was administered to 200 Australian students in grade 10 together with measures of Holland's RIASEC interest themes and scholastic aptitudes. The correlations between scales from the three domains showed clearly that beliefs made a contribution distinct from that provided by aptitudes and interests. Even though the results may reflect possible sampling or method variance, career beliefs in this sample added unique information to that traditionally used in career counseling. 相似文献

Summary. The system for monitoring suicides in Hong Kong has considerable delays in reporting as the cause of death needs to be determined by a coroner's investigation. However, timely estimates of suicide rates are desirable to assist in the formulation of public health policies. This motivated us to develop a non-parametric procedure to estimate the intensity function of a Poisson process in the presence of reporting delays. We give closed form estimators of the Poisson intensity and the delay distribution, conduct simulation studies to evaluate the method proposed and derive their asymptotic properties. The method proposed is applied to estimate the intensity of suicide in Hong Kong. 相似文献

《发展和完善南宁市新型农村合作医疗制度研究》课题组 《创新》2008,2(3)
近年来,党和政府一直把发展和完善新型农村合作医疗制度作为改善民生的一项重要工作。南宁市新型农村合作医疗尽管有了较大的发展,但与同为西部省会城市的西安、昆明、成都相比还存在不少差距。这就需要结合地方实际,从运行机制、资金监管、信息化管理、人才建设等软、硬件方面破解新型农村合作医疗制度发展和完善的难题。 相似文献

Globalisation raises numerous problems for contemporary public relations theory. In a world where the geographic reach of organisations routinely spans cultures and nation states and where issues of culture, economics and politics are inseparably intertwined, the discipline of public relations has established a distance from the immediacy of the marketplace, failed to fully engage with discussions of culture. By taking a relentlessly managerialist approach, theorists have also failed to recognise the true complexity of public relations practice and this has marginalised aspects of practice that, though nebulous and intangible, are none the less real. This paper argues that attention needs to shift towards the complexities of practice, in order to recapture and theorise a distinctive occupational field with the aim of better understanding the relationship between universal humanising principles, on the one hand, and the purposive demands of capital, on the other; the attempt to theorise how public relations makes profitable sense in society. The paper was prompted by the author's reflections on auto-ethnographic research into the public relations field, part of an ongoing research project. 相似文献
