Previously reported observed data on risky everyday driving are brought together and reanalyzed in order to focus on the relation between risky driving and the size of the car being driven, as indicated by car mass. The measures of risky driving include separation between vehicles in heavy freeway traffic and speed on a two lane road. Observed seat belt use provides a third measure of driver risk. Confounding effects arising from the observed association between car mass and driver age are taken into account by segmenting the data into three driver age groups. Driver risk taking is found to increase with increasing car mass for each of these three aspects of everyday driving. The implications of these results with respect to driver fatality rates are discussed in terms of a simple model relating observed risky driving to the likelihood of involvement in a severe crash. 相似文献

Privatisation of the state-owned British railway system was completed in 1997. The following 6 years saw four serious fatal train accidents, leading to 49 deaths. These were the train collisions at Southall in 1997 and Ladbroke Grove in 1999, each caused by trains passing red signals, and the derailments at Hatfield in 2000 and Potters Bar in 2002, each caused by defective track. Has safety been compromised by the sell-off of the railways? Andrew Evans looks at the evidence and asks has privatisation led to more accidents? 相似文献

This article explores the role of women's inheritance and ownership of property in urban Senegal. It shows how being able to inherit and own property promotes the economic and emotional security of widows and their children in urban areas, and discusses the challenges posed by legal pluralism in working on poverty alleviation and social protection in the city. 相似文献

This paper examines divisions between majority and minority ethnic groups over attitudes towards minority rights in 13 East European societies. Using national sample surveys and multilevel models, we test the effectiveness of competing explanations of ethnic polarization in attitudes towards minority rights, as well as regional and cross-national differences in levels of polarization. We find that, at the individual level, indicators of ‘social distance’ (inter-marriage and social interaction) account most effectively for the extent of ethnic polarization. However, regional and cross-national variations in polarization between majority and minority groups are explained most effectively by cultural (linguistic and religious) differences. These findings accord with research in the West, indicating the importance of cultural differences as a source of ethnic polarization, while offering little support for theories focusing on economic and structural factors or the size of minority groups. They also suggest the likely sources of difficulties for democratic consolidation in ethnically divided post-communist societies. 相似文献

Workfare is, at least in part, a policy response to changing labour markets and the expansion taking place in jobs that are low‐paid, irregular and insecure. For lone mothers, increasingly the focus of workfare policies, precarious employment creates special challenges. However, the nature of the jobs that are available to women on social assistance has received relatively little attention in the workfare literature, which focuses more on individual characteristics, supports to employment, and programme impacts. Drawing upon both primary and secondary sources and using Ontario, the province with the most developed workfare programme in Canada, this article examines the ways in which policies support and enforce precarious employment. The article also considers the implications of precarious employment for UK policy, which has not (yet) adopted workfare for lone mothers, although incremental steps in that direction are taking place as employment is increasingly viewed as the appropriate objective of income support programmes for lone mothers. 相似文献

The technological approach to risk regulation seeks to lessen the incidence of mortality and morbidity by modifying environmental conditions. Insofar as risk-taking behavior is purposive, social scientists have predicted that technological progress may be negated by various forms of risk compensation. The validity of this hypothesis is tested in the transportation sector with data from the U.S. on the effects of new mandatory safety-belt-use laws. A fixed-effects model of traffic fatality counts is estimated using pooled data from 50 states during the 1975–1987 period. Results suggest that such laws have reduced mortality among car occupants to a degree that is compatible with the predictions of technologists. However, there is weak evidence of increased mortality among some nonoccupants, a pattern predicted by risk-compensation theorists. The lifesaving effects of belt-use laws are largest in states that permit primary police enforcement and appear to be somewhat larger for front-seat occupants age 21 and under. Although offsetting behavior appears to be small relative to lifesaving effects, it may take several more years for any compensatory behavior to achieve a new equilibrium.This research was supported in part by a grant from the Centers for Disease Control to the New England Injury Prevention Research Center. 相似文献

This article adopts a comparative perspective on policies to increase labour force participation of single mothers. Australia's orientation is briefly explored within the context of other major English-speaking countries (the United States, Britain and Canada), and the common emphasis in the policies on providing employment services and reducing poverty traps for Australia and Canada's largest province (Ontario) is then examined. While the potential of these approaches to increase labour force participation is found to be limited, the comparison suggests that Canada would do well to follow some of the recent anti-poverty measures Australia has adopted. Australia, however, appears to offer a less favourable employment climate for women. The article concludes that both jurisdictions will need to pursue a broader set of policies to respond to the root causes of poverty among women heading families on their own. 相似文献

Ethylene oxide is a gas produced in large quantities in the United States that is used primarily as a chemical intermediate in the production of ethylene glycol, propylene glycol, non-ionic surfactants, ethanolamines, glycol ethers, and other chemicals. It has been well established that ethylene oxide can induce cancer, genetic, reproductive and developmental, and acute health effects in animals. The U.S. Environmental Protection Agency is currently developing both a cancer potency factor and a reference concentration (RfC) for ethylene oxide. This study used the rich database on the reproductive and developmental effects of ethylene oxide to develop a probabilistic characterization of possible regulatory thresholds for ethylene oxide. This analysis was based on the standard regulatory approach for noncancer risk assessment, but involved several innovative elements, such as: (1) the use of advanced statistical methods to account for correlations in developmental outcomes among littermates and allow for simultaneous control of covariates (such as litter size); (2) the application of a probabilistic approach for characterizing the uncertainty in extrapolating the animal results to humans; and (3) the use of a quantitative approach to account for the variation in heterogeneity among the human population. This article presents several classes of results, including: (1) probabilistic characterizations of ED10s for two quantal reproductive outcomes-resorption and fetal death, (2) probabilistic characterizations of one developmental outcome-the dose expected to yield a 5% reduction in fetal (or pup) weight, (3) estimates of the RfCs that would result from using these values in the standard regulatory approach for noncancer risk assessment, and (4) a probabilistic characterization of the level of ethylene oxide exposure that would be expected to yield a 1/1,000 increase in the risk of reproductive or developmental outcomes in exposed human populations. 相似文献
