Starting in 2006, respondents in the biennial U.S. Health and Retirement Study were asked to submit biomarkers every other wave and were notified of several results. Rates of undiagnosed high blood pressure and diabetes according to these biomarkers were 1.5 % and 0.7 %, respectively. An intent-to-treat analysis suggests that collection and notification had small effects on the average respondent and may have reduced health care utilization. Among respondents who received notification of potentially dangerous biomarker levels, subsequent rates of new diagnosis and associated pharmaceutical usage increased by 20 to 40 percentage points, an order of magnitude above baseline. High blood glucose A1C was associated with a 2.2 % drop in weight and an increase in exercise among respondents without a previous diagnosis of diabetes. Notifications appear also to have altered health behaviors by spouses, suggesting household responses to health maintenance. Biomarker collection seems to have altered circumstances for an interesting minority of HRS respondents.  相似文献

Drawing on detailed case studies of four large service sector organizations this paper finds little evidence of training provision that links skills development with incremental career progression. Past policies of ‘delayering’ have opened up a ‘gap’ in the job ladder and this has both increased the organizational costs of formal training and reduced the likelihood of informal on‐the‐job training being seen as the basis for promotion to the next level. Managers are thus faced with the challenge of how to establish a new set of premises upon which to strengthen the workforce's loyalty and commitment to the organization, in the context of problems of high staff turnover and low job satisfaction. What we find is a greater emphasis on certificated training provision. However, in the absence of a transparent career path employers rely on more intensive techniques of appraisal and selection of workers for a ‘winner‐takes‐all’ career path. Given the importance of skills acquisition as an important building block of the ‘learning society’, our findings suggest that policymakers in Britain cannot rely solely upon the employer to bridge the skill gap evident in large service sector organizations.  相似文献

Australia's income support arrangements have come under increasing scrutiny lately reflecting a growing concern about high levels of youth unemployment and about low levels of full-time education participation. This paper aims to explore the relationship between education participation and financial incentives and to assess as a possible direction for future reform, the concept of a single and universal youth allowance. The paper begins by outlining the major forms of income support available to young people and illustrates some of the complexities in the youth income support structure. The evidence on the importance of financial factors conflicts, particularly between economists and non-economists. This is in part explained by the different conceptual frameworks used. Other possible reasons are canvassed as to why studies have so far not thrown much light on the role of financial factors in the education participation decision. The paper also outlines specific directions of distortion contained in current payment relativities. Several difficulties with the proposal for a single youth allowance as a means of increasing education participation are discussed and alternatives briefly outlined. The concluding section of the paper summarises the issues relevant to the future debate on youth income support and identifies areas for further research.  相似文献

Abstract It is well recognized that the informal economy—unregulated economic activities that generate real or in-kind income—features prominently in the day-to-day lives of many in the developing world. Researchers have begun to explore the informal economy in developed countries but this work has focussed primarily on urban areas to the neglect of rural areas. In this paper the nature and correlates of informal work in nonmetropolitan Pennsylvania are described through an analysis of survey data on 505 families. Results indicate that participation in informal activities is widespread, is not more typical of the poor, does not contribute greatly to family income on average but does help many poor families weather difficult economic times, is both economically and noneconomically motivated, and, net of other sociodemographic variables, is positively related to rurality of residence and formal labor supply.  相似文献

The Lake Pontchartrain Basin in southeast Louisiana is an estuarine watershed encompassing New Orleans, Baton Rouge, and wetlands that are an integral part of Louisiana's unique culture. In recent decades rapid growth and poorly planned development have resulted in a decrease in water quality and habitat loss, especially in St. Tammany Parish on the north shore of Lake Pontchartrain. In 1989, the Lake Pontchartrain Basin Foundation (LPBF), an environmental, non-profit organization, was formed to address and rectify environmental issues in the Basin. LPBF accomplishes its mission through programs addressing water quality, habitat protection, geographic information science, public access, and education.LPBF used the recent, rapid development occurring in St. Tammany Parish as a case study to examine the relationship between land use, water quality, and development in the Basin by investigating habitat change/urbanization, development in flood plains, and water quality. Through the integration of LPBF programs, it was found that urbanization is having a devastating impact on the parish's natural habitats and severely degrading water quality. Using these results, LPBF is educating Basin citizens on the protection of their habitats and water quality to insure that these resources may be available for future generations.  相似文献

This study examined the emergence of affect specificity in infancy. In this study, infants received verbal and facial signals of 2 different, negatively valenced emotions (fear and sadness) as well as neutral affect via a television monitor to determine if they could make qualitative distinctions among emotions of the same valence. Twenty 12‐ to 14‐month‐olds and 20 16‐ to 18‐month‐olds were examined. Results suggested that younger infants showed no evidence of referential specificity, as they responded similarly to both the target and distracter toys, and showed no evidence of affect specificity, showing no difference in play between affect conditions. Older infants, in contrast, showed evidence both of referential and affect specificity. With respect to affect specificity, 16‐ to 18‐month‐olds touched the target toy less in the fear condition than in the sad condition and showed a larger proportion of negative facial expressions in the sad condition versus the fear condition. These findings suggest a developmental emergence after 15 months of age for affect specificity in relating emotional messages to objects.  相似文献

When parents divorce, child support and visitation must be determined. The 1988 Family Support Act requires all states to have child support guidelines for courts to use in determining child support obligations. However, many divorcing couples arrive at agreements without court intervention, or they simply fail to enforce the court decision ex post. Given that the guidelines provide a starting point for negotiations, couples may be able to find self-negotiated, Pareto-improving solutions. In this paper we model the bargaining process that divorcing couples engage in when coming to agreements on visitation and child support. The model suggests that individuals may arrive at agreements that are Pareto improvements for both parents but that the children's welfare may decline as a result of these self-negotiated settlements. Data from the Stanford Child Custody Study show that the changes made in child support and visitation agreements are consistent with our model in only 30 percent of the cases. Therefore, we consider alternative specifications of the model and show that both significant costs of enforcing the original agreement and alternative assumptions on parental preferences can explain these empirical results.  相似文献
