Married individuals are healthier than single individuals though the reasons are not well understood. Individuals with spouses/or partners are less likely to smoke. We explore the relationship between health and marital status by analyzing three potential channels through which marriage affects smoking, i.e., consumption externalities (one spouse's smoking affects the other spouse's welfare), altruism (one spouse reduces smoking in response to the other spouse's bad health), and learning about risks of smoking from the health experience of one's spouse. We find spousal health does not affect smoking due to altruism or learning within the household but do find evidence for consumption externalities.  相似文献

Kelly and Cutright (1983), using regression techniques, conclude that birth control is among the more important determinants of Swedish illegitimacy. To derive this conclusion, they use changes in the marital fertility of wives aged 35-39 as a proxy for birth control. They maintain that annual change in the marital fertility rate of wives aged 35-39 is not likely to be greatly influenced by annual change in factors other than birth control. The "argument" appears to derive from the "desired family size" model of childbearing--a basic assumption of social demography. In it simplest form it states that most couples do not practice birth control until they reach a preconceived goal, or desired family size. It thus implies that a change in family size preferences will most affect the birth control practices of the oldest reproductive age groups. The simple form of the model has been questioned by the failure of Western couples to reproductively compensate for a major proportion of their child deaths, by the proportions of Western couples who say they would have preferred larger families than they actually had, by the predictive inadequacy of family size preferences, and by suggestions that age may be the more important determinant of reproduction. As a result some demographers now concede its inadequacy. Others are trying to relax its assumptions, with as yet problematic success. Essentially every Western fertility decline to date has been characterized by an increasing concentration of childbearing in the youngest age groups. In discussing this pattern social demographers have maintained that it could only have come about by a decline in family size preferences. This then is the standard argument supporting Kelly and Cutright's proxy for birth control. The authorities who offer it generally ignore the difficulties with the desired family size model and simply assert without justification that couples do in fact conform to it. Data on the age patterns of chronic disease and on the reproductive effects of environmental stressors suggest that the modern age pattern of fertility could also be produced by a deteriorating environment. Kelly and Cutright are incorrect in asserting that factors other than voluntary birth control could not be responsible for changes in fertility at ages 35-39. At best they may argue that their proxy is uniquely definitive provided that the desired family size model can be saved and provided the health of Western populations has not been compromised by technological change. At issue is a debate between what Dunlap calls the human exemptionalist and the ecological world views.  相似文献

Ten days after the Symbionese Liberation Army's shoot out in Los Angeles in 1974, the Cedars-Sinai Medical Center, Department of Family Child Psychiatry, Thalians Community Mental Health Center, sent a crisis team of three psychotherapists to a school in the black community. The psychotherapists used an art therapy approach with a third grade classroom of 21 black children. The team's procedure helped the children ventilate their reactions to a frightening event which occurred in their neighborhood. This paper describes the art therapy techniques which were utilized, the children's vivid pictorial and verbal expressions accompanied by the psychological aspects of their responses.  相似文献

Differences in patient characteristics, including age, sex, and race influence the safety and effectiveness of drugs, biologic products, and medical devices. Here we provide a summary of the topics discussed during the opening panel at the 2018 Johns Hopkins Center for Excellence in Regulatory Science and Innovation symposium on Assessing and Communicating Heterogeneity of Treatment Effects for Patient Subpopulations: Challenges and Opportunities. The goal of this session was to provide a brief overview of FDA-regulated therapeutics, including drugs, biologics and medical devices, and some of the major sources of heterogeneity of treatment effects (HTE) related to patient demographics, such as age, sex and race. The panel discussed the US Food and Drug Administration's role in reviewing and regulating drugs, devices, and biologic products and the challenges associated with ensuring that diverse patient populations benefit from these therapeutics. Ultimately, ensuring diverse demographic inclusion in clinical trials, and designing basic and clinical research studies to account for the intended patient population's age, sex, race, and genetic factors among other characteristics, will lead to better, safer therapies for diverse patient populations.  相似文献

This article examines poverty and welfare provision in early twentieth-century Beijing as dialogue and transaction between the city government and the urban poor. Earlier studies of the Chinese urban have tended to emphasize the material aspects of urban development, and the efforts of planners and city governments to modernize China’s cities, rather than the human experience of the city. This article draws on the extensive archives of the Beijing Municipal Government Social Affairs Bureau to extend our understanding of the experience of poverty and the agency of the poor. The archive confirms that Beijing’s growing and increasingly formalized welfare institutions were designed to discipline the poor as they alleviated poverty. However, the correspondence between applicants for welfare and the Social Affairs Bureau also reveals that the poor often approached these institutions instrumentally and assertively. Recourse to the welfare institute became a livelihood tactic, a claim on the authorities in pursuit of which certain sub-groups within the poor mobilized intangible assets, from social networks to understanding of the intended terms of the system, to sway the terms of their engagement with the authorities in their own favour.  相似文献

The present study was initiated to investigate levels and predictors of wellbeing among inhabitants of intentional communities (ICs). An anonymous, Internet-based questionnaire was distributed to US and Canadian ICs. Responses were obtained from 913 members. Wellbeing was measured by the widely used satisfaction with life scale (SWLS). Hierarchical linear regression analyses were run to test the predictive validity of Social support, Identity fusion, Meaning in life, Community satisfaction and Life change, and Religious activity above and beyond demographic variables and personality traits. Mean scores on the SWLS were estimated to 5.27 and 5.47 (1–7 scale) for men and women, respectively. The full model explained 41.4% of the variance for men and 38.2% for women. Personality explained 13.4 (men) and 14.4% (women) of the variation, while demographic variables only had a minor impact. Overall, presence of Meaning in life and Social support were the most important predictors. The IC inhabitants reported wellbeing on par with the highest scores previously published. The findings support the contention that sustainability, in the form of a communal lifestyle of low ecological footprint, may be promoted without forfeiting wellbeing.  相似文献

Cross-sectional research on internationally adopted children has indicated an association between early attachment disturbances and language deficits. Raaska et al. (2013 Raaska, H., Elovainio, M., Sinkkonen, J., Stolt, S., Jalonen, I., Matomäki, J., … Lapinleimu, H. (2013). Adopted children's language difficulties and their relation to symptoms of reactive attachment disorder: FinAdo study. Journal of Applied Developmental Psychology, 34(3), 152160.[Crossref], [Web of Science ®] [Google Scholar]) have speculated that this relationship is likely bidirectional. In an attempt to elucidate the causal relationship between these two risk factors, the attachment disturbances and language skills of 44 internationally adopted children were assessed in a cross-lagged structural equation model. Greater attachment disturbances at wave 1 predicted less gain in language by wave 2. In contrast, language at wave 1 was not predictive of attachment disturbances at wave 2. These results suggest that early attachment problems may present an important risk for later language development and should be an immediate and primary focus of post-adoptive intervention for families adopting internationally.  相似文献
