The cost of uncertain life span 总被引:1,自引:1,他引:0
Ryan D. Edwards 《Journal of population economics》2013,26(4):1485-1522
Much uncertainty surrounds the length of human life. The standard deviation in adult life span is about 15 years in the USA, and theory and evidence suggest that it is costly. I calibrate a utility-theoretic model that shows that 1 year in standard deviation is worth about half a life year. Differences in variance exacerbate health inequalities between and among rich and poor countries. Accounting for the cost of life-span variance appears to amplify recently discovered patterns of convergence in world average human well-being because the component of variance due to infant mortality has exhibited even more convergence than life expectancy. 相似文献

Juvenile delinquency remains a significant problem for child welfare systems throughout the United States. Victims of child abuse and neglect are more likely relative to children in the general population to engage in delinquency (Ryan & Testa, 2005; Widom, 1989). Although the magnitude of this relationship is not fully understood (Zingraff, Leiter, Myers, & Johnsen, 1993), the risk of delinquency is particularly high for African American males, adolescents, and children in substitute care settings. Unfortunately little is known about the factors that connect the experiences of maltreatment and delinquency. This lack of knowledge makes it nearly impossible to decrease the risk of delinquency for children in foster care. To improve the understanding of juvenile delinquency in the child welfare system, the current study tests aspects of social control theory within the context of foster care. We focus specifically on the effects of foster parent-foster child attachment, commitment, and permanence. The results indicate that strong levels of attachment decrease the risk of delinquency for youth in foster care. Involvement with religious organizations also decreases the risk of delinquency. In contrast, perceptions of placement instability, placement with relatives, and school suspensions are associated with an increased risk of delinquency. 相似文献

This study examined heterosexism that is not specifically targeted at LGB individuals, but may be experienced as antigay harassment, and may contribute to the stigma and stress they experience. LGB participants (N = 175, primarily Euro-American college students), read scenarios of heterosexuals saying or assuming things potentially offensive to gay men or lesbian women. For each scenario, they indicated extent to which they would be offended and less open about their sexuality, and their perceptions of the behaviors as evidence of antigay prejudice. Not only did respondents find the scenarios to be offensive and indicative of prejudice, but perceived offensiveness was associated with a decreased likelihood of coming out. In comparison to gay men, lesbian women and bisexuals found the scenarios more offensive and more indicative of prejudice. Limitations of the current study and directions for future research are outlined. 相似文献

Slum clearance and rebuilding first became a serious political project in Toronto during the 1930s. Following the release of a systematic housing survey known as the Bruce Report (1934), a set of actors distinguished by their planning authority with respect to social agencies, influence over social work education, coordination of social research, and role as spokespersons of religious bodies inaugurated a political struggle over state power. While the campaign failed, it called forth a reaction from established authorities and reconfigured the local political field as it related to low-income housing. This article gives an account of these processes by drawing upon correspondence and minutes of meetings of city officials and the campaign’s organizers, newspaper clippings, and published materials. 相似文献

Age is often used in law and public policy as a low-cost proxy for competency, maturity, and ability. Age is also used in
numerous sport (and non-sport) labor markets to determine workplace eligibility. We exploit the enactment of the women’s professional
tennis minimum age rule (AR) in 1995 to estimate the effects of ARs on short-run and long-run labor market outcomes. We find
very limited evidence that the AR has had any systematic beneficial effect on players’ career longevity or success. Our results
suggest that sport governing bodies should (re-)evaluate the efficacy and necessity of “one size fits all” age eligibility
rules. 相似文献

This paper describes the findings of a critical ethnographic research study conducted in an urban long-term care home. While our intention was to learn more about the culture of care, specifically as it relates to mental health care provision, the participants in the study consistently spoke with us about (what we have labeled as) a culture of compliance. In a context where new long-term care legislation is being implemented along with new, standardized resident assessment instruments, gaining a deeper understanding of the (un)intended consequences of government's efforts to ensure a high quality of care is of paramount importance. This research demonstrates how policy-driven structural mechanisms can (re)produce conditions that result in frontline staff being afraid and unable to care, and thus contributes to a better understanding of the lived experience of frontline long-term care staff who find that their caregiving responsibilities are displaced by caregiving accountabilities. 相似文献

A total of 19 people with dementia were interviewed as part of a study into unmet respite care need amongst caregivers and day-care attenders in Sheffield. Some important contextual debates associated with conducting social research with people with dementia are considered. These include informed consent, competency, and how the interests of caregivers and people with dementia are bound together. A form of process consent was used in conducting semi-structured interviews with day-care attenders. Day-care attenders spoke about 'being here' in a number of ways. These include their initial experiences, their sources of satisfaction and their sense of being in families. These substantive findings and the associated methodological insights suggest day-care attenders have important things to say as service-users if appropriate strategies for listening are employed. Service-providers can collaborate imaginatively with day-care attenders to actively explore how care might be shaped by the experiences of persons with dementia. 相似文献

Drawing on both organizational behaviour and employee relations perspectives,the paper defines participation as `opportunity to influence decisions,' andconsiders the impact of the micro-political behaviour of organization membersin pursuit of their interests on the development of genuine participation.Three types of micro-political strategy are identified and their implicationsdiscussed: information control, flexibility, and stage-craft. The discussionis illustrated with findings from an international study of decision making,and brief comment is made on international cultural differences as acomplicating factor. It is suggested that the role of participation in enhancing the knowledge baseof the organization has been neglected. If genuine participation is to beinstituted, decision making will become more complex, requiring negotiation,not only of competing interests but also of what is to be accepted as`knowledge' in the organization. This in turn will place greater demands onthe intellectual skills and personal behaviour of participants. 相似文献

Estimation of finite mixture models when the mixing distribution support is unknown is an important problem. This article gives a new approach based on a marginal likelihood for the unknown support. Motivated by a Bayesian Dirichlet prior model, a computationally efficient stochastic approximation version of the marginal likelihood is proposed and large-sample theory is presented. By restricting the support to a finite grid, a simulated annealing method is employed to maximize the marginal likelihood and estimate the support. Real and simulated data examples show that this novel stochastic approximation and simulated annealing procedure compares favorably with existing methods. 相似文献
