We investigate the extent to which the tax-and-transfer system of the United Kingdom equalizes opportunities for income attainment among citizens. Within the framework of Roemer’s theory of Equality of Opportunity, and using individual data from the British Household Panel Survey from 1991 to 2008, we calculate the tax rates necessary to equalize opportunities for different circumstances. We provide a ranking of these circumstances by the degree to which they influence income attainment. Although pre-fisc equality of opportunity increases over time, the tax rate necessary to equalize opportunities remains higher than the observed tax rate. Only under a relatively high labour supply elasticity the observed UK tax rate fares well in equalizing opportunities for income attainment.  相似文献

Significant quantities of toxic metals are emitted to the air by the incineration of waste, as well as by the combustion of coal and oil. To optimize the regulations for their emissions one needs to know the cost of their damage. That requires an impact pathway analysis, with realistic dispersion models, exposure‐response functions, and monetary values. In this article we explain the method and assumptions and present results for arsenic, cadmium, mercury, and lead, the most important toxic metals in terms of damage cost. We also estimate their contribution to the damage cost of waste incineration and electric power from coal for typical situations in Europe. The damage costs of As, Cd, and Pb are much higher than previous estimates because of a large number of new epidemiological studies, implying more and more serious health effects than what had been known before. New cost‐benefit studies for the abatement of toxic metal emissions are advisable. The discussion of the epidemiological studies and the derivation of exposure‐response functions are presented in two companion articles, one for As and Cd, the other for Hg and Pb.  相似文献

Once language is understood in terms of competing discourses, competing ways of giving meaning to the world, which imply differences in the organization of social power, then language becomes an important site of political struggle.  相似文献

Within a system concept role delineation and communicational patterns of black, disadvantaged families are evaluated on the basis of 15 years experience. The observations made at best are suggestive and meant to highlight certain features of a black, disadvantaged family system. In the light of these observations some suggestions regarding technique are offered, notably the use of multiple family therapy as a way of increasing therapeutic effectiveness and facilitating movement in the system.  相似文献

The extracellular matrix accumulates biologically active advanced glycation endproducts such as carboxymethyl-lysine (CML). Alikhani et al. recently reported that CML-rich collagen, representing an artifically aged matrix protein, induces apoptosis in vivo and in fibroblasts. This observation may have profound implications for the biology of cell-matrix interactions during aging.  相似文献

Although the framing of public opinion has often been conceptualizedas a collective and social process, experimental studies offraming have typically examined only individual, psychologicalresponses to alternative message frames. In this research weemploy for the first time group conversations as the unit ofanalysis (following Gamson 1992) in an experimental study offraming effects. Two hundred and thirty-five American citizensin 50 groups (17 homo-geneously conservative groups, 15 homogeneouslyliberal groups, and 18 heterogeneous groups) discussed whetheror not gay and lesbian partnerships should be legally recognized.Groups were randomly assigned to one of two framing conditions(a "homosexual marriage/special rights" frame or a "civil union/equalrights" frame). Results indicated framing effects that were,in all cases, contingent on the ideological leanings of thegroup. The "marriage" frame tended to polarize group discussionsalong ideological lines. Both liberal and conservative groupsappeared to find their opponents’ frame more provocative,responding to them with a larger number of statements and expressinggreater ambivalence than when reacting to more hospitable frames.  相似文献

Sociological understanding of generations can be enhanced by avoiding defining them rigidly as chronological cohorts but rather linking people's accounts of their generational experience with an historically informed political economy. It then becomes possible, for example, to understand the complexity of generational politics. This paper uses data on the 'War Generation' taken from the Exeter Politics of Old Age project to link an empirically based political economy of generational inequality with a cultural sociology of generations. The 'War Generation' recognizes itself and is referred to by others in terms of a common identity. It is also an historical generation; its values, attitudes and, above all, sense of national solidarity and mutual obligation were forged in the direct experience of war. But it is also divided by divergent economic interests in property and pension rights based on the historical experience of the life course by successive groups and this segmentation can be observed in political action. The political culture of the War Generation manifests both continuity and change. Understanding these dynamics requires listening to people constructing their worlds, understanding their full range of historical experiences, and analysing the conditions for their conflicts and their cohesion.  相似文献

Typologies of government–voluntary sector relations mostly categorize nation-level situations, and omit consideration of intra-national differences. They are also rarely subject to empirical testing and subsequent theoretical development. This paper reports on research to apply Kuhnle and Selle's (2002) relational typology, which characterizes the experience of “Britain,” to a study of Scottish and English voluntary organizations' relations with government. Contrary to Kuhnle and Selle, the paper demonstrates — through survey data — a divergence between Scotland and England, within the “British” context, and advances the case for further testing of such conceptual typologies. The methodological challenges in moving from a theoretical framework to a research design capable of field application, using survey methods, are illustrated and discussed. Further directions for theoretically led work are suggested.  相似文献

Under the act that established the National Health Insurance Scheme (NHIS), persons 70 years of age or above are automatically enrolled in the scheme and therefore can access health services free at the point of use. This suggests that the elderly who are unable to afford the premiums of private health insurance can enrol in the NHIS thereby eliminating the possibility of disparities in health insurance coverage. Notwithstanding, few studies have examined health insurance coverage among the elderly in Ghana. The lack of studies on the elderly in Ghana may be due to limited data on this important demographic group. Using data from the Study on Global Ageing and Health and applying logit models, this paper investigates whether the pro-poor exemption policy is eliminating disparities among the elderly aged 70 years and older. The results show that disparities in insurance coverage among the elderly are based on respondents’ socio-economic circumstances, mainly their wealth status. The study underscores the need for eliminating health access disparities among the elderly and suggests that the current premium exemptions alone may not be the solution to eliminating disparities in health insurance coverage among the elderly.  相似文献
