In 1980, the U.S. Supreme Court vacated a revised occupational standard for benzene, stating that the Occupational Safety and Health Administration (OSHA) had failed to demonstrate that significant health risks existed under the current standard. This decision has been interpreted by OSHA as requiring the consideration of quantitative risk assessments, whenever possible, in the development of regulations for occupational carcinogens. In light of this decision, the available epidemiologic evidence was used to generate a quantitative risk assessment for benzene. Uncertainties regarding the levels and lengths of benzene exposure for the studied cohorts were incorporated into the analysis. Based on the one-hit model, the assessment indicates that a working lifetime exposure to benzene at the current permissible exposure level (10 ppm) poses a substantial excess risk of death from leukemia. This report discusses the calculation of the risk estimates, the basis for relying on certain assumptions, and the inherent limitations of using epidemiologic studies to quantify cancer risks. 相似文献

Since enacting a unique facility siting law in 1981, Wisconsin has had unusual success in siting solid-waste management facilities. The law mandates a state-level technical review and licensing process and a local-level negotiation/arbitration process that deals with host community impacts and concerns. Data from the negotiated compensation agreements, a survey of facility proposers, and secondary data for the host communities are analyzed in relation to compensation levels. Concerns with community image and health risks and with facility management and equity issues are found to significantly and substantially increase negotiated compensation levels. In contrast, a focus on logistics and transportation concerns is associated with lower levels of compensation. Compensation increases with facility capacity but at a less than proportional rate. Higher levels of compensation are obtained by communities that accept compensation "in kind" in the form of free or reduced fees for host community waste disposal. 相似文献

A Road Oft Taken: Unaffordable Home Energy Bills,Forced Mobility And Childhood Education in Missouri
Roger D. Colton 《Journal of Children and Poverty》1996,2(2):23-39
This study explores the interconnection between two seemingly unrelated problems: unaffordable home energy bills and poor educational attainment. The study goes beyond the self-evident observation that if hungry children make bad students, cold children would make bad students as well. Instead, the study focuses on the well-documented relationship between frequent household mobility and poor educational attainment. Looking specifically at a group of low-income households in Missouri, the study evaluates to what extent, if at all, unaffordable home energy bills contribute to frequent household mobility and, therefore, by extension, to the educational problems facing students in those households. 相似文献

Subjective expected utility maximization is derived from four axioms, using an argument based on the separating hyperplane theorem. It is also shown that the first three of these axioms imply a more general maximization formula, involving an evaluation function, which can still serve as a basis for decision analysis. 相似文献

Research on satisfaction with community services has used both age and life cycle stage as predictors of satisfaction. As both age and life cycle stage are indicators of life course, their relative advantages in service satisfaction research need to be assessed. The authors correlated both age and life cycle stage with twenty service satisfaction items and with item non-response (a measure of the salience of a service). Results were: (1) associations with service satisfaction were linear, (2) some associations with salience were markedly curvilinear, and (3) as predictors of service satisfaction, age and life cycle performed similarly. The choice between age and life cycle as predictors of service satisfaction appears to involve conceptual as well as empirical issues. 相似文献

Advisors on strategic planning often give two separate pieces of advice to managers: first, managers must interact with rather than react to the external environment. That is, they should be proactive, not reactive. Second, the organizational effectiveness must be improved. However, seldom is any linkage established between these two pieces of advice. The first premise is primarily an external view, and the second is an internal view. If these two views are not linked, the results may range from slightly below optimum to bankruptcy. The purpose of this article is to show how these two views can be linked. 相似文献

How do schemas about self-salience--the importance of the self versus the collective in social relations--affect mental health? We propose that self-salience shapes the likelihood of experiencing internalizing or externalizing problems. Schemas that privilege others over the self increase the risk of internalizing symptoms, including depressive symptoms and anxiety, whereas those that privilege the self over others predispose individuals to externalizing behaviors of antisocial behavior and substance abuse. Furthermore, we propose that these schemas contribute to the gender differences that exist in these problems. We test these predictions with data from adolescents, the stage at which these problems and the gender differences in them arise. Results show that self-salience underlies both internalizing and externalizing problems. In addition, schemas about self-salience help explain the gender differences found in mental health problems. 相似文献
