Some heuristic tests for detection of existence of errors in inspection are proposed. Some of these tests are only effective if the sampling fraction ((sample size)/(lot size)) is rather large, and in all cases their application predicates special experiments to provide the requisite data. Feasibility of these experiments will vary according to specific circumstances. 相似文献

The process of globalization is transforming society with unprecedented speed and scope. Along the way, social roles are being altered and identities are being transformed. How do the forces of globalization shape the self? How do changes to the self affect social relationships and alter larger social structures? This paper offers a conceptual framework for addressing these questions. The ‘role‐as‐resource’ perspective is employed as a tool for differentiating between two opposing processes. On the one hand, top down forces associated with technocapitalism serve to colonize the self by sustaining roles associated with global consumption and production, while disrupting or erasing traditional roles. On the other hand, bottom‐up forces associated with local grassroots organizations and democratic social movements facilitate resistance by providing resources for a more agentic political self. 相似文献

The idea that a child should not have sexual interests and experiences is fast being supplanted by the knowledge that he does have them; that they are an expression of perfectly normal, healthy energies, and that while it is necessary to gain control over them, they should not be forcibly suppressed” ( Renz & Renz 1935 : 92). 相似文献

The authors report on the frequency and nature of alcohol advertisements in a representative sample of college newspapers from 1984/85 and compare these with results of a similar study conducted 7 years earlier, in 1977/78. On average, nearly 24 column inches of space per issue were devoted to national alcohol advertisements in 1984/85. This represents a significant decrease from an earlier period. The space devoted to national alcohol advertisements, however, still far exceeded that for comparison products (books, soft drinks). Local alcohol advertisements averaged 20 column inches per issue and were somewhat more frequent than in the previous study. The content of the advertisements differed markedly from the messages presented 7 years earlier. Although national alcohol advertisements in 1977/78 frequently ridiculed education and study, none did so in 1984/85, when appeals were to taste and product quality instead. Fantasy themes also were relatively common. Very few national alcohol advertisements featured athletes or group drinking. Sponsorship of campus activities by the alcohol industry, however, had increased since the earlier study. In contrast to national advertisements, many local advertisements consisted of inducements to drink through special offers and happy hours. Some encouraged irresponsible and heavy drinking. Interestingly, alcohol advertisements were just as frequent in papers from states with higher minimum drinking ages and were more frequent in papers from campuses with higher proportions of women students. 相似文献

Probabilistic insurance is an insurance policy involving a small probability that the consumer will not be reimbursed. Survey data suggest that people dislike probabilistic insurance and demand more than a 20% reduction in the premium to compensate for a 1% default risk. While these preferences are intuitively appealing they are difficult to reconcile with expected utility theory. Under highly plausible assumptions about the utility function, willingness to pay for probabilistic insurance should be very close to willingness to pay for standard insurance less the default risk. However, the reluctance to buy probabilistic insurance is predicted by the weighting function of prospect theory. This finding highlights the potential role of the weighting function to explain insurance. 相似文献

Parent and sibling influences on children's development of conflict management strategies were examined. Data consist of naturally occurring, in‐home sibling disputes of 37 families at two time points. The siblings were approximately two and four years old at Time 1, and four and six years old at Time 2. Parents' and children's use of conflict strategies that reflect proactive autonomy assertions such as opposition and verbal and physical power were the focus of the current study. Results suggest that parents and siblings play an important role in shaping children's conflict behaviours over time. For instance, parents' reliance on unelaborated opposition to the child, and older siblings' increased use of physical power predicted decreases in younger siblings' ability to assert themselves during conflict. In addition, increased proportions of opposition from a younger sibling was associated with the older siblings using less verbal aggression and using more mature conflict strategies such as justifying their own behaviour to their younger sibling. As sibling conflict is a salient child rearing concern for parents, practical implications are discussed. 相似文献

The present study was aimed at assessing the health consequences of the presence of radon in Quebec homes and the possible impact of various screening programs on lung cancer mortality. Lung cancer risk due to this radioactive gas was estimated according to the cancer risk model developed by the Sixth Committee on Biological Effects of Ionizing Radiations. Objective data on residential radon exposure, population mobility, and tobacco use in the study population were integrated into a Monte‐Carlo‐type model. Participation rates to radon screening programs were estimated from published data. According to the model used, approximately 10% of deaths due to lung cancer are attributable to residential radon exposure on a yearly basis in Quebec. In the long term, the promotion of a universal screening program would prevent less than one death/year on a province‐wide scale (0.8 case; IC 99%: –3.6 to 5.2 cases/year), for an overall reduction of 0.19% in radon‐related mortality. Reductions in mortality due to radon by (1) the implementation of a targeted screening program in the region with the highest concentrations, (2) the promotion of screening on a local basis with financial support, or (3) the realization of systematic investigations in primary and secondary schools would increase to 1%, 14%, and 16.4%, respectively, in the each of the populations targeted by these scenarios. Other than the battle against tobacco use, radon screening in public buildings thus currently appears as the most promising screening policy for reducing radon‐related lung cancer. 相似文献
