Who am I? Concepts of disability and their implications for people with learning difficulties 总被引:1,自引:1,他引:0
Philip Harris 《Disability & Society》1995,10(3):341-352
The relationship between concepts of disability, group membership and self-concept was examined. It was argued that people with learning difficulties have been categorised, by non-disabled people, as 'belonging' to a devalued social group with a rigid boundary based on IQ level. Findings from studies of self-concept have shown little evidence of a sense of belonging. It was suggested that people with learning difficulties may prefer not to identify with this social group because of the negative effect it may have on their self-esteem. The analysis based on intergroup and social identity theories proposed that people with learning difficulties may be encouraged in creating a positive self-concept by abandoning the IQ criterion for social categorisation; softening the boundaries between disabled and non-disabled people; and adopting collective rather than individual strategies for social change. 相似文献

To quantify the health benefits of environmental policies, economists generally require estimates of the reduced probability of illness or death. For policies that reduce exposure to carcinogenic substances, these estimates traditionally have been obtained through the linear extrapolation of experimental dose-response data to low-exposure scenarios as described in the U.S. Environmental Protection Agency's Guidelines for Carcinogen Risk Assessment (1986). In response to evolving scientific knowledge, EPA proposed revisions to the guidelines in 1996. Under the proposed revisions, dose-response relationships would not be estimated for carcinogens thought to exhibit nonlinear modes of action. Such a change in cancer-risk assessment methods and outputs will likely have serious consequences for how benefit-cost analyses of policies aimed at reducing cancer risks are conducted. Any tendency for reduced quantification of effects in environmental risk assessments, such as those contemplated in the revisions to EPA's cancer-risk assessment guidelines, impedes the ability of economic analysts to respond to increasing calls for benefit-cost analysis. This article examines the implications for benefit-cost analysis of carcinogenic exposures of the proposed changes to the 1986 Guidelines and proposes an approach for bounding dose-response relationships when no biologically based models are available. In spite of the more limited quantitative information provided in a carcinogen risk assessment under the proposed revisions to the guidelines, we argue that reasonable bounds on dose-response relationships can be estimated for low-level exposures to nonlinear carcinogens. This approach yields estimates of reduced illness for use in a benefit-cost analysis while incorporating evidence of nonlinearities in the dose-response relationship. As an illustration, the bounding approach is applied to the case of chloroform exposure. 相似文献

This article explores two problems analysts face in determining how to estimate values for children's health and safety risk reductions. The first addresses the question: Do willingness‐to‐pay estimates for health risk changes differ across children and adults and, if so, how? To answer this question, the article first examines the potential effects of age and risk preferences on willingness to pay. A summary of the literature reporting empirical evidence of differences between willingness to pay for adult health and safety risk reductions and willingness to pay for health and safety risk reductions in children is also provided. The second dimension of the problem is a more fundamental issue: Whose perspective is relevant when valuing children's health effects—society's, children's, adults‐as‐children, or parents'? Each perspective is considered, followed ultimately by the conclusion that adopting a parental perspective through an intrahousehold allocation model seems closest to meeting the needs of the estimation problem at hand. A policy example in which the choice of perspective affects the outcome of a regulatory benefit‐cost analysis rounds out the article and emphasizes the importance of perspective. 相似文献

There are increasing and multiple pressures on nonprofit organizations to demonstrate excellence in performance. Although there is a growing literature on the various approaches to performance improvement taken by nonprofits, little is known about the processes involved in the adoption and implementation of specific approaches. This article is about the adoption and use of one approach to performance improvement, “quality systems,” in the U.K. nonprofit sector. We report findings about factors that encourage nonprofits to adopt quality systems. We also analyze the distinctive challenges of implementing quality approaches in a nonprofit sector context and suggest critical success factors. The article concludes with a discussion of the organizational and policy implications of applying the management concepts of quality and performance to the nonprofit sector. 相似文献

Dealing with Toxicity in the Risk Society: The Case of the Hamilton,Ontario Plastics Recycling Fire*
S. Harris Ali 《Revue canadienne de sociologie》2002,39(1):29-48
Une perspective de la construction sociale sert de cadre a l'analyse des controverses sur la gestion des risques qui ont été provoquées à la suite d'un incendie majeur dans une usine de recyclage de matières plastiques à Hamilton, en Ontario. En mettant l'accent sur les processus de réclamation au c?ur de l'interaction entre les représen‐tants du gouvernement, les acteurs environnementaux, les experts techniques et les résidants, il a été révélé qu'un accent trop limité aux questions d'ordre technique avait mené a l'exclusion des préoccupations fondées sur la rationalité culturelle ayant ainsi entraine un cadre d'interaction très litigieux divisant profondément. Les conséquences des conclusions empiriques de la thése de la société des risques ainsi que de la théorie sur la communication des risques sont explorées. A social construction perspective is applied in the analysis of the risk management controversies that arose in response to a large toxic fire that occurred at a Hamilton, Ontario plastics recycling facility. By focussing on the claimsmaking processes involved in the interaction of government officials, environmental movement actors, technical experts, and residents, it was found that an overly narrow focus on technical matters led to the exclusion of lay concerns based on cultural rationality, thereby resulting in a very contentious and divisive setting for interaction. Implications of the empirical findings for the risk society thesis and risk communication theory are explored. 相似文献

Occupational segregation by sex remains the most pervasive aspect of the labour market. In the past, most research on this topic has concentrated on explanations of women’s segregation into low paid and low status occupations, or investigations of women who have crossed gender boundaries into men’s jobs, and the potential impact on them and the occupations. In contrast, this article reports on a small‐scale, qualitative study of ten men who have crossed into what are generally defined as ‘women’s jobs’. In doing so, one of the impacts on them has been that they have experienced challenges to their masculine identity from various sources and in a variety of ways. The men’s reactions to these challenges, and their strategies for developing and accommodating their masculinity in light of these challenges, are illuminating. They either attempted to maintain a traditional masculinity by distancing themselves from female colleagues, and/or partially (re)constructed a different masculinity by identifying with their non‐traditional occupations. This they did as often as they deemed necessary as a response to different forms of challenge to their gender identities from both men and women. Finally, the article argues that these responses work to maintain the men as the dominant gender, even in these traditionally defined ‘women’s jobs’. 相似文献

Any continuous bivariate distribution can be expressed in terms of its margins and a unique copula. In the case of extreme‐value distributions, the copula is characterized by a dependence function while each margin depends on three parameters. The authors propose a Bayesian approach for the simultaneous estimation of the dependence function and the parameters defining the margins. They describe a nonparametric model for the dependence function and a reversible jump Markov chain Monte Carlo algorithm for the computation of the Bayesian estimator. They show through simulations that their estimator has a smaller mean integrated squared error than classical nonparametric estimators, especially in small samples. They illustrate their approach on a hydrological data set. 相似文献

This article discusses the policy and politics of dual nationality in Germany. It contrasts the policy reality, in which dual nationality is tolerated in a wide range of cases, with Germany's continued opposition in principle to this phenomenon. It then analyzes political, cultural and electoral factors to explain why this opposition persists despite these widespread exceptions. In conclusion, the article argues that by continuing formally to oppose dual nationalities, Germany in effect discourages naturalizations and thereby continues to operate a broadly exclusive citizenship. 相似文献
