Changing Chinese family patterns caused by immigration have contributed to the breakdown of traditional community and familial control in Chinese-American families. As a result, the Chinese-American elderly are faced with unique psychosocial problems that workers must consider when providing services to this population. 相似文献

Two surveys were conducted of volunteers working for recreation organizations in four New South Wales regions. The results highlight the dependence of these organizations on volunteers. Volunteers were found to be heavily engaged in instructing and organizing recreation activities. Few have any specific training for the role although further training is frequently considered desirable by respondents. Many respondents indicated that the government could assist voluntary work by providing— ? training at the local level, ? general financial assistance, and ? subsidies for equipment and facilities. Generally, responses indicate that the government should play a supportive rather than controlling role in recreation. 相似文献

John H. Ehrenreich 《Analyses of Social Issues and Public Policy》2003,3(1):15-28
The concept of "psychological trauma" conflates emotional responses to traumatic events such as motor vehicle accidents, muggings, and house fires, responses to natural disasters such as earthquakes and volcanic eruptions, and responses to war, chronic physical abuse, prolonged torture, and repeated gang-rape as an act of "ethnic cleansing." It is argued that, from a psychological, human, and moral perspective, use of a single construct to describe responses to such a range of horrific happenings makes no sense. The benefits and limits of conceptualizing PTSD as a unifying concept for describing psychological responses to calamitous events are discussed. The consequences (with respect to clinical work, research, and social policy) of failing to distinguish between responses to relatively circumscribed traumatic events, more extreme, prolonged, or repeated individual traumatization, and collectively experienced mass violence against entire communities are examined. 相似文献

The Role of Child Emotionality in Child Behavior and Maternal Instruction on Planning Tasks 总被引:1,自引:0,他引:1
This study explored the relation of children's emotional functioning to children's behavior during individual planning and mother's and children's behaviors during joint planning. Participants were 118 mothers and their second‐grade children. Mothers rated children on their emotional intensity and children rated themselves on their use of emotion regulation strategies. Children and mother–child dyads were videotaped during planning tasks and independent observers rated their behavior. Child emotional intensity was directly related to children being less engaged in the task and to an emphasis in maternal instruction on regulatory behaviors. Some types of emotion regulation strategies modified these relations. Findings suggest that child emotionality may play an important role in the early school years in children's opportunities to learn during social‐cognitive activity. 相似文献

We introduce the notion of a dice model as a framework for describing a class of probabilistic relations. We investigate the transitivity of the probabilistic relation generated by a dice model and prove that it is a special type of cycle-transitivity that is situated between moderate stochastic transitivity or product-transitivity on the one side, and ukasiewicz-transitivity on the other side. Finally, it is shown that any probabilistic relation with rational elements on a three-dimensional space of alternatives which possesses this particular type of cycle-transitivity, can be represented by a dice model. The same does not hold in higher dimensions. 相似文献

Several decision rules, including the minimax regret rule, have been posited to suggest optimizing strategies for an individual when neither objective nor subjective probabilities can be associated to the various states of the world. These all share the shortcoming of focusing only on extreme outcomes. This paper suggests an alternative approach of tempered regrets which may more closely replicate the decision process of individuals in those situations in which avoiding the worst outcome tempers the loss from not achieving the best outcome. The assumption of total ignorance of the probabilities associated with the various states is maintained. Applications and illustrations from standard neoclassical theory are discussed. 相似文献
