Abstract. Most research on the relationship between health and socio‐economic status (SES) controls for age or investigates the relationship for a particular age range. This paper, however, examines the effect of SES on health across different age groups. Using data from the German Socio‐Economic Panel and controlling for health–SES endogeneity, we find that the health–income relationship does vary across the life cycle and between genders and different labor force status, with the impact of income on health relatively more pronounced for younger cohorts. The unemployed also have lower levels of health at all levels of income.  相似文献

Our question is quite simple: If agriculture protectionism is a product of economic development, why is agriculture protected at such varying degrees by otherwise similarly developed countries? Previous attempts to fit agriculture into general models of trade policy formation have relied exclusively on producer demand for protection and merely assume the associated demand for lower prices that might come from consumers. Not surprisingly, these previous studies add only minimally to this strange phenomenon. Our method turns this approach on its head by modeling the political strategy of agriculture protection on the costs incurred by the consumer. Taking both producers and consumers into account more accurately reflects the intent of extant theoretical models of protectionism. Our results show that using the consumer as the dependent variable provides more robust results on common independent variables. Recent global events show that consumer disapproval of agriculture policies should not be underestimated by political scientists or politicians.  相似文献

We propose a mixture of latent variables model for the model-based clustering, classification, and discriminant analysis of data comprising variables with mixed type. This approach is a generalization of latent variable analysis, and model fitting is carried out within the expectation-maximization framework. Our approach is outlined and a simulation study conducted to illustrate the effect of sample size and noise on the standard errors and the recovery probabilities for the number of groups. Our modelling methodology is then applied to two real data sets and their clustering and classification performance is discussed. We conclude with discussion and suggestions for future work.  相似文献

BackgroundAbout one third of refugee and humanitarian entrants to Australia are women age 12–44 years. Pregnant women from refugee backgrounds may have been exposed to a range of medical and psychosocial issues that can impact maternal, fetal and neonatal health.Research questionWhat are the key elements that characterise a best practice model of maternity care for women from refugee backgrounds? This paper outlines the findings of a project which aimed at developing such a model at a major maternity hospital in Brisbane, Australia.Participants and methodsThis multifaceted project included a literature review, consultations with key stakeholders, a chart audit of hospital use by African-born women in 2006 that included their obstetric outcomes, a survey of 23 African-born women who gave birth at the hospital in 2007–08, and a survey of 168 hospital staff members.ResultsThe maternity chart audit identified complex medical and social histories among the women, including anaemia, female circumcision, hepatitis B, thrombocytopenia, and barriers to access antenatal care. The rates of caesarean sections and obstetric complications increased over time. Women and hospital staff surveys indicated the need for adequate interpreting services, education programs for women regarding antenatal and postnatal care, and professional development for health care staff to enhance cultural responsiveness.Discussion and conclusionsThe findings point towards the need for a model of refugee maternity care that comprises continuity of carer, quality interpreter services, educational strategies for both women and healthcare professionals, and the provision of psychosocial support to women from refugee backgrounds.  相似文献

Adams, Gupta and Leeth ( British Journal of Management , 2008) question the universality of the glass cliff after finding no differences in US companies' financial performance either before or after the appointment of male and female CEOs. We agree that glass cliffs are neither universal nor ineluctable, but urge caution in interpreting this null result. This is because the nature and significance of women's precarious leadership positions becomes more apparent when one goes beyond archival financial data and compares the broad circumstances of male and female leaders. Here multiple strands of research suggest that above the glass ceiling the playing field for men and women is far from level.  相似文献

Objectives

Previous criminological scholarship has posited that network ties among neighborhood residents may impact crime rates, but has done little to consider the specific ways in which network structure may enhance or inhibit criminal activity. A lack of data on social ties has arguably led to this state of affairs. We propose to avoid this limitation by demonstrating a novel approach of extrapolatively simulating network ties and constructing structural network measures to assess their effect on neighborhood crime rates.

Methods

We first spatially locate the households of a city into their constituent blocks. Then, we employ spatial interaction functions based on prior empirical work and simulate a network of social ties among these residents. From this simulated network, we compute network statistics that more appropriately capture the notions of cohesion and information diffusion that underlie theories of networks and crime.

Results

We show that these network statistics are robust predictors of the levels of crime in five separate cities (above standard controls) at the very micro geographic level of blocks and block groups.

Conclusions

We conclude by considering extensions of the approach that account for homophily in the formation of network ties.  相似文献

A sample (N = 706) of children, adolescents, young adults, and older adults were surveyed with regard to their views of family. Young adults endorsed more nontraditional views than children and older adults and were more likely than other age groups to indicate that there is no best family type. Children and older adults were more likely than adolescents and young adults to endorse married or living together parents as the best family type. Women and respondents who had experienced parental divorce endorsed traditional views of family less strongly, but women also endorsed stronger expectations for their own family formation. Findings support the possibility of both developmental and sociocontextual influences on attitudes toward family life.  相似文献

This article is based on the findings from a subset of gender identity and sexual orientation questions from The Casey Field Office Mental Health Study (CFOMH). It aims to contribute the experiences of youth in the care of Casey Family Programs to the increasing body of research on lesbian, gay, bisexual, transgender, or questioning (LGBTQ) youth in foster care, as well as inform future studies in this area. The CFOMH study interviewed 188 adolescents ages 14 to 17 who were receiving foster care services from Casey Family Programs in 2006. The experiences in care of youth who identified as LGBQ (n = 10) are presented in narrative form, along with data from all youth in care (N = 188) regarding their perceptions of the foster care environment for LGBTQ youth. These findings are intended to underscore the need to conduct a larger, more in-depth study of the experiences of LGBTQ youth in foster care and the environment that foster care provides for them.  相似文献

A sample (N?=?365) of middle school and high school students from both divorced and intact families were surveyed with regard to their opinions about the impact of their parents' relationships (divorced or married) on a variety of areas of their lives. Adolescents from separated or divorced (S/D) families tended to rate their parents' relationships and impact on them more negatively than adolescents from living together or married (L/M) families. However, both groups consistently rated their parents in the same direction on a variety of topics. Gender was not a factor in the responses of either group. However, age (middle school vs. high school) was related to significant differences in adolescents' views about parents.  相似文献
