Preschool children observed two models, one of whom (controller of resources) controlled rewards dispensed to the child and to the other model (rival consumer of resources). The nurturance of the controller was varied in terms of his relative generosity towards the subject and rival consumer. Controllers were imitated to a greater extent than consumers only when the controller had been more nurturant to the child than to the rival consumer. Imitation of the controller and consumer were affected differently by the various conditions of nurturance, but children's learning of each model's behaviors were affected similarly by the conditions. The learning and imitative performance of each model's behaviors were uncorrelated, and imitation of one model did not correlate with imitation of the other. However, the learning of the two models' behaviors was highly correlated. 相似文献

Ray Fitzpatrick 《Ethical Theory and Moral Practice》1999,2(1):37-46
A remarkable surge in efforts to assess the quality of life of patients has occurred in recent years in medical research. Philosophical discussions of these developments have focused, on the one hand, on epistemological reservations about the plausibility of measuring quality of life and, on the other hand, on moral and ethical qualms about the meaning of life conveyed in such assessments. Whilst providing an important note of caution, such critiques fail to recognise two basic principles of quality of life in medical research. Firstly it is intended to provide understanding about groups and categories of patients rather than individuals. Secondly the purpose of such research is to produce generalisations about the relative costs and benefits of specific health care interventions rather than absolute judgements regarding the quality of life of patients per se. Selecting a good quality of life measure for a clinical trial requires balancing criteria such as validity with practical feasibility. Such measures will play an increasingly central role in providing research evidence to improve health care. 相似文献

This cross-sectional study examined risk and asset factors thought to be associated with fighting among a sample of 1,642 African American children and adolescents in a central Alabama school district. Results show that poor grades, parental abuse, and gang affiliation were significant risk factors associated with higher frequency of fighting. Results also show that parental monitoring and being happy at school were associated with lower frequency of fighting, suggesting the importance of continued support for outreach to parents and further efforts to reduce or eliminate the community factors that promote proliferation of gangs. Programs, either for an entire community or a school system within a community, must be sensitive to the specific risks, assets, and outcomes of that environment so that prevention and intervention are sensitive to cultural, environmental, and demographic distinctions in target populations. 相似文献
