In this article, we examine the association between the legalization of abortion with the 1973 Roe v. Wade decision and youth homicide in the 1980s and 1990s. An interrupted time series design was used to examine the deaths of all U.S. 15- to 24-year-olds that were classified as homicides according to the International Classification of Diseases (codes E960-969) from 1970 to 1998. The legalization of abortion is associated over a decade later with a gradual reduction in the homicides of White and non-White young men. The effect on the homicides of young women is minimal. We conclude that the 1990s decline in the homicide of young men is statistically associated with the legalization of abortion. Findings are not consistent with several alternative explanations, such as changes in the crack cocaine drug market. It is almost inconceivable that in the United States of today, policies affecting the choice to have children would be justified as a means to control crime. Yet, if the legalization of abortion had this unintended effect, the full range of policy implications needs to be discussed. 相似文献

Disability as the Basis for a Social Movement: Advocacy and the Politics of Definition 总被引:2,自引:0,他引:2
Richard K. Scotch 《The Journal of social issues》1988,44(1):159-172
Many people with disabilities do not identify themselves as disabled or choose not to be part of a politically active community of disabled persons. This paper discusses both the barriers to the formation of a social movement of disabled people and the ways in which these barriers have been overcome. The role of public policy in the evolution of this movement is discussed, as are the current status and prospects of the disability rights movement. 相似文献

Status quo bias in decision making 总被引:7,自引:3,他引:7
Most real decisions, unlike those of economics texts, have a status quo alternative—that is, doing nothing or maintaining one's current or previous decision. A series of decision-making experiments shows that individuals disproportionately stick with the status quo. Data on the selections of health plans and retirement programs by faculty members reveal that the status quo bias is substantial in important real decisions. Economics, psychology, and decision theory provide possible explanations for this bias. Applications are discussed ranging from marketing techniques, to industrial organization, to the advance of science. 相似文献

In a majority rule voting game, the uncovered set is the set of alternatives each of which can defeat every other alternative in the space either directly or indirectly at one remove. Research has suggested that outcomes under most reasonable agenda processes (both sincere and sophisticated) will be confined to the uncovered set. Most research on the uncovered set has been done in the context of voting games with a finite number of alternatives and relatively little is known about the properties of the uncovered set in spatial voting games.We examine the geometry of the uncovered set in spatial voting games and the geometry of two important subsets of the uncovered set, the Banks set and the Schattschneider set. In particular, we find both general upper and lower limits on the size of the uncovered set, and we give the exact bounds of the uncovered set for situations with three voters. For situations with three voters, we show that the Banks set is identical to the uncovered set. 相似文献

Correspondence to John Harris, School of Health and Social Studies, University of Warwick, Coventry CV4 7AL, UK. E-mail: j.harris{at}warwick.ac.uk Summary The notion that social work is an international profession,operating with generally similar goals, methodologies, and commonvalues is considered critically. Examining the political andsocial contexts of three countries with liberal democratic governmentsAustralia,Britain and the United Statesthe role of social workwithin the welfare processes of each country is compared. Whilesocial work as an identifiable professional activity sharessome features, it is argued that the idea of its having a coreessence needs to be tempered with a realistic assessment ofthe importance of contextually created difference. Recent andrapid developments in the institutional context, such as thoseexperienced in these three countries, further underscore thelimited utility of the notion of a common professional project. 相似文献

When a risk is exchanged, the exact value for the minimum price (positive or negative) that the purchaser (investor, or insurer) is willing to pay is given by the certainty equivalent wealth level, which in turn depends on his specific utility function. When this utility function is unknown, then only a sufficient condition on the price can ever be found. This paper provides methods for calculating such a sufficient condition, when only limited information on the utility function is known. 相似文献

Two alternative models of service provision are associated with decriminalisation of public drunkenness – the medical or sickness model and the social welfare model. In the development of alternative strategies to accompany decriminalisation, Australian jurisdictions have largely followed the latter welfare approach. In Western Australia, decriminalisation of public drunkenness was spurred by the recommendations of the Muirhead Interim Report on Aboriginal Deaths in Custody. A community development approach was used to establish local management structures for sobering-up programs in areas of greatest need. Three sobering-up centres are now operating in the State with a fourth centre due to open in mid 1993. Some preliminary evaluation of the Western Australian program has been carried out but a more comprehensive research and evaluation program is being conducted to assess the impact of decriminalisation and the development of alternative responses. 相似文献
