The emphasis in class research remains on the structural aspects of class, class processes are neglected. This paper focuses upon some relational and normative aspects of class through an examination of social divisions produced and constructed within middle class families’ choices of childcare. Working with data from two contrasting settings in London (Battersea and Stoke Newington) three issues are addressed in the paper; the extent to which childcare arrangements both substantively and structurally position children differently within long term educational careers; the ways in which the use of choice in a market system of child care and education, works to produce patterns of social closure that quietly discriminate via the collectivist criterion of class and racial membership; and the ways in which child care choices also point‐up and perpetuate subtle distinctions and tensions of values and lifestyle within the middle class, between class factions. Concepts drawn from the work of Bourdieu are deployed throughout.  相似文献

Taxes on tobacco provide a significant income for the Australian government — $5.1 billion in 2001. At the same time, health officials are making strenuous efforts to reduce smoking, particularly among teenagers. Some economists suggest that raising taxes on tobacco will produce more revenue while at the same time lowering smoking rates, particularly among youths who have less discretionary spending power than adults. But a by‐product of excise tax in Australia has been the emerging market in “chop‐chop,” tobacco diverted from legal channels by growers who receive considerably higher prices for a part of their yield than they can obtain from legal manufacturers. The article details this situation and suggests that only bold solutions may be able to reduce tensions in tax policies, smoking rates and the “chop‐chop” black market.  相似文献

In 2002 Save the Children UK carried out a study of child poverty in Uganda, as part of the on‐going Uganda Participatory Poverty Assessment Programme. Using participants from all regions of the country, the researchers asked children about their perceptions of poverty and anti‐poverty strategies, as well as questioning adult key informants about trends in child poverty, vulnerable groups and the effectiveness of government policies in tackling child poverty. This article reports on one aspect of the study, looking at the different indicators that children use to assess poverty, and comparing these with official poverty monitoring indicators. It finds that while some areas—notably, health, education and water and sanitation—are well documented, others, which may be as, or more significant to children's welfare, such as child abuse or quality of parental care, are almost totally neglected. A more holistic framework for assessing child poverty is proposed.  相似文献

Experimental data were compiled for seven soybean varieties studied at four different locations in the U.S. for a period of one to three years. Three dose–response functions (linear, quadratic, and Weibull) were fitted, as appropriate, to the experimental data. Effects of acid deposition on soybean yields were estimated by combining variety-specific dose–response and production data. These calculations suggest that U.S. soybean production (2.2 billion bushels in 1982) would increase by 3.2 million bushels with a 10% reduction in 1982 hydrogen ion concentration levels in all counties where soybeans were grown, and by almost 70 million bushels with uniform improvement to pH 5.2. These estimates are based on many simplifying assumptions and are subject to several important sources of uncertainty explored in this study. The calculated changes are small in comparison with effects from other natural and anthropogenic stresses.  相似文献

We propose a bubble game that involves sequential trading of an asset commonly known to be valueless. Because no trader is ever sure to be last in the market sequence, the game allows for a bubble at the Nash equilibrium when there is no cap on the maximum price. We run experiments both with and without a price cap. Structural estimation of behavioral game theory models suggests that quantal responses and analogy‐based expectations are important drivers of speculation.  相似文献
