Metaphors provide bold, rich and distintive windows on the world. They offer dynamic and dramatic views beyond the surface of things into their deeper significance. This paper offers guidelines for discovering and developing metaphors in clinical practice with individuals and families. It also demonstrates how dramatization techniques are used to extend, enlarge and shape metaphors for effective diagnosis and treatment. It builds upon real case material of active metaphorical work with individuals and families for illustrative exposition. 相似文献

Over the past 20 years, several epidemiological studies have found an association between exposure to electromagnetic fields (EMFs) and health effects, including childhood leukemia and adult brain cancer. However, experts strongly disagree about whether this association is causal and, if so, how strong it is. In this article, we examine several alternatives to reduce EMFs from sources of the California power grid, including undergrounding distribution and transmission lines and reconfiguring or rephasing lines. The alternatives were evaluated in terms of the potential health risk reduction, cost, impacts on service reliability, property values, and many other consequences. Because of the uncertainty about an EMF-health link, the main effort was to determine the sensitivity of the decisions to the probability and seriousness of an EMF hazard. User-friendly computer models were developed to allow stakeholders to change the model assumptions and parameters to analyze the impacts of their own assumptions and estimates on the decision. The analysis clearly demonstrated that only four of the many concerns raised by the stakeholders could make a difference in the decision: health risks, costs, service reliability, and property values. Whether undergrounding, moderate alternatives for EMF reduction, or no change was the best decision depended on a few key factors, including the probability that EMF exposure is a hazard, the severity of this hazard, how the EMF reduction measures are financed, and the impacts on property values. While the analysis did not resolve the EMF issues, it showed that even in the most controversial settings, a little analysis goes a long way to clarifying the issues and to focus the debate. 相似文献

Summary. An authentic food is one that is what it purports to be. Food processors and consumers need to be assured that, when they pay for a specific product or ingredient, they are receiving exactly what they pay for. Classification methods are an important tool in food authenticity studies where they are used to assign food samples of unknown type to known types. A classification method is developed where the classification rule is estimated by using both the labelled and the unlabelled data, in contrast with many classical methods which use only the labelled data for estimation. This methodology models the data as arising from a Gaussian mixture model with parsimonious covariance structure, as is done in model-based clustering. A missing data formulation of the mixture model is used and the models are fitted by using the EM and classification EM algorithms. The methods are applied to the analysis of spectra of food-stuffs recorded over the visible and near infra-red wavelength range in food authenticity studies. A comparison of the performance of model-based discriminant analysis and the method of classification proposed is given. The classification method proposed is shown to yield very good misclassification rates. The correct classification rate was observed to be as much as 15% higher than the correct classification rate for model-based discriminant analysis. 相似文献

Abstract This study examines variation in filial responsibility expectations-the extent to which adult children are expected to assist and care for their aging parents-among a sample of 440 older persons. The analysis focuses on the relationship of filial responsibility expectations to residential location and tests the hypothesis that older rural residents have higher expectations for assistance from their children than do older urbanites. Current residential location is found to have little impact on expectations, but older persons who were raised in rural areas, particularly on farms, have significantly higher expectations for filial assistance than do older persons from urban backgrounds. Possible consequences of these patterns for the transmission of expectations from parents to children are discussed. 相似文献

The relationship between First and Third World scholarship may be characterized as a type of ideological dependency. This
dependency can be seen in the founding of sociology departments in many Third World universities that followed closely the
development of tertiary education during the colonial and postcolonial periods. These departments provide an important link
between Third World aspirations to modernize and First World production of sociological knowledge for rationalizing modern
experiences. They can therefore be considered a type of institutional measure of the fate of modernity in the Third World.
Because of the quest for modernity in the Third World, postmodernism will not likely be considered seriously as a reevaluation
of and challenge to modernity. The institutionalization of sociology and its probable response to postmodernism will be examined
in the context of a Third World nation, namely Malaysia. 相似文献

An exploratory study of thirteen Japanese-American gay men residing in the Los Angeles area found that those men who had disclosed their sexual orientation to family members were more likely to express more positive attitudes concerning a variety of issues. Detailed personal accounts of these patterns are presented along with discussions of how Asian homosexuals maintain their “double-minority” identities as both Japanese and gay. 相似文献

Receipt of food stamps is often observed to be positively correlated with intake of nutrients. However, this observed fact could be the result of self-selection into the food stamp program by those individuals who are more interested in maintaining good nutrition. We observe that, controlling for participation in the food stamp program, nutrition is negatively affected by food stamp income for a sample of elderly people. However, we find that the levels of nutrients do not decrease enough to cause individuals to fall below the Recommended Dietary Allowance. 相似文献
