In this paper, we use a longitudinal survey that has collected information for 50 years on a large cohort of Wisconsin high school graduates and their siblings to examine the long term impact of early occupational choice on health status. We find evidence that beginning a career in a blue collar occupation is correlated with several measures of poor health outcomes at ages 50–65. Since our dataset includes usually unobserved pre-labor market characteristics, including IQ and childhood health status, we can show that controlling for these variables is important for many results and suggests a high level of selection into occupation based on health and ability. We also provide evidence of gender differentials in the association between first occupation and later health. Then, we replace our basic measure of occupational categories with summary measures of job characteristics and find that employment at “bad jobs” at the beginning of an individual’s career predicts later health outcomes. Finally, we use sibling information in the dataset to show that unmeasured family background factors explain a large share of the effects of occupation on later health. Overall, the evidence points to limited, though heterogeneous, long term effects of health from blue collar employment.  相似文献

In light of the recent concerns regarding the solvency of Social Security’s Old-Age, Survivors and Disability Insurance (OASDI), private pensions may play an increasingly important role in retirement welfare of US retirees. However, the private pension landscape has evolved in ways that may result in lower private pension wealth for retirees. One recent such phenomenon involves the conversion of traditional defined benefit pension plans to cash balance plans, which results in lower pension benefits for many workers. In this study, I investigated how characteristics of the firm’s workforce influenced whether the firm converted their traditional pension plan to a cash balance plan and how these characteristics related to the firm’s pension plan policy more generally. Using the Longitudinal Employer-Household Data and pension plan data from the Department of Labor/Internal Revenue Service and the Pension Benefit Guaranty Corporation, I found little evidence of workforce age distribution effects on the likelihood of DB plan conversion to a cash balance plan in the 1990s. More generally, I consistently found positive associations between firms with older and more female workforces and defined contribution plans during the same time.  相似文献

Organizational institutionalism has shown how institutional entrepreneurs can introduce new logics into fields and push for their broader acceptance. In academic science in the United States, however, market logic gained strength without such an entrepreneurial project. This article proposes an alternative “practice selection” model to explain how a new institutional logic can gain strength when local innovations interact with changes outside the field. Actors within a field are always experimenting with practices grounded in a variety of logics. When one logic is dominant, innovations based on alternative logics may have trouble gaining the resources they need to become more broadly institutionalized. But if a changing environment starts systematically to favor practices based on an alternative logic, that logic can become stronger even in the absence of a coherent project to promote it. This is what happened in US academic science, as growing political concern with the economic impact of innovation changed the field’s environment in ways that encouraged the spread of local market-logic practices.  相似文献

This article draws upon recent works in sociology, jurisprudence, and feminist theory in order to assess the ways in which feminism, and sex and gender more generally, have become intricately interwoven with punitive agendas in contemporary US politics. Melding existing theoretical discussions of penal trends with insights drawn from my own ethnographic research on the contemporary anti-trafficking movement in the United States—the most recent domain of feminist activism in which a crime frame has prevailed against competing models of social justice—I elaborate upon the ways that neoliberalism and the politics of sex and gender have intertwined to produce a carceral turn in feminist advocacy movements previously organized around struggles for economic justice and liberation. Taking the anti-trafficking movement as a case study, I further demonstrate how human rights discourse has become a key vehicle both for the transnationalization of carceral politics and for the reincorporation of these policies into the domestic terrain in a benevolent, feminist guise. I conclude by urging greater and more nuanced attention to the operations of gender and sexual politics within mainstream analyses of contemporary modes of punishment, as well as a careful consideration of the neoliberal carceral state within feminist discussions of gender, sexuality, and the law.  相似文献

Water quality trading (WQT) is a market arrangement in which a point-source water polluter pays farmers to implement conservation practices and claims the resulting benefits as credits toward meeting a pollution permit. Success rates of WQT programs nationwide are highly variable. Most of the literature on WQT is from an economic perspective emphasizing property rights, transaction costs, and the role of the price signal, but this institutional approach cannot fully account for the differential success rates between and within WQT programs. In this paper I turn to the role of social embeddedness and trust in helping explain these variable outcomes. Using interview data from all WQT programs nationwide I demonstrate that differential success rates between, and particularly within programs is largely determined by the presence or absence of a trusted local intermediary with relationships to the farming community. Trust helps WQT programs succeed because it makes information more credible to farmers, makes outreach to farmers more efficient, and buffers the risk that farmers may perceive in participating in the trading scheme.  相似文献

People living with disabilities (PWD) face unique problems in dealing with conventional healthcare facilities. We investigate the experiences of PWD as they access healthcare facilities in rural Namibia. More specifically, we investigate structural–environmental and process barriers to accessing health facilities. The study relied on semi-structured interviews and purposive sampling. The results showed PWD find it difficult to walk to health centers for treatment due to lack of transport, money to pay for treatment and toilet facilities and the distance is too far for people with lower-limb disabilities. There is a need to consider the unique issues affecting access to healthcare for people living with disabilities to achieve equitable access to healthcare services.  相似文献

When early testing indicates a hearing loss, parents find themselves on a roller-coaster of experiences leaving little time or space for reflection. This study is based on interviews with families in the Flemish region of Belgium, one of the earliest in the world to introduce universal neonatal screening for hearing loss. Starting from a phenomenological approach, we explore parents’ accounts of their experiences in order to uncover the meanings of early parenting of a child identified with a label. Soon after birth, these parents encounter a different world in which intertwined discourses construct parenthood with a deaf child. During the process of becoming a parent, representations of deafness as impairment were omnipresent. In contrast to a medical and technological perspective that insists on the need to intervene as fast as possible, it is argued that the private and social implications of rapid intervention require explicit consideration.  相似文献

The aim of this paper is to discuss the contribution of two complementary approaches for designing and evaluating new driver support systems likely to improve the operation and safety of the road traffic system. The first approach is based on detailed analyses of traffic crashes so as to estimate drivers' needs for assistance and the situational constraints that safety functions should address to be efficient. The second approach is based on in depth-analyses of behavioral adaptations induced by the usage of new driver support systems in regular driving situations and on drivers' acceptance of the assistance provided by the systems.  相似文献
