Behavioural models of migration emphasize the importance of migration decision-making for the explanation of subsequent behaviour. But empirical migration research regularly finds considerable gaps between those who intend to migrate and those who actually realize their intention. This paper applies the Theory of Planned Behaviour, enriched by the Rubicon model, to test specific hypotheses about distinct effects of facilitators and constraints on specific stages of migration decision-making and behaviour. The data come from a tailor-made panel survey based on random samples of people drawn from two German cities in 2006–07. The results show that in conventional models the effects of facilitators and constraints on migration decision-making are likely to be underestimated. Splitting the process of migration decision-making into a pre-decisional and a pre-actional phase helps to avoid bias in the estimated effects of facilitators and constraints on both migration decision-making and migration behaviour.  相似文献

I employ high quality register data to present new facts about income mobility in Sweden. The focus of the paper is on regional differences in mobility, using a novel approach based on a multilevel model. This method is well suited when regions differ greatly in population size, as is the case in Sweden. The maximum likelihood estimates are substantially more precise than those obtained by running separate OLS regressions. I find that few regions are statistically significantly different from the Swedish average when measuring mobility in relative terms, while a greater number of regional differences emerge when focusing on absolute outcomes. Compared to growing up in the least favorable region, children from the most favorable region with parents located at the 25th percentile in the income distribution reach higher income ranks corresponding to approximately one monthly salary for an average Swedish worker per year.  相似文献

Background

Physical activity is considered an effective measure to promote health in older people. There is evidence that the number of outdoor trips increases physical activity by increasing walking duration. The objective of this study was to analyse the relationship between daily time out-of-home and walking duration. Furthermore, predictors for walking duration and time out-of-home were evaluated.

Methods

Walking duration was measured prospectively over a 1 week period by a body-fixed sensor and the time out-of-home was assessed by a questionnaire at the same days. Seven thousand, two hundred and forty-three days from 1289 older people (mean age 75.4 years) with both sensor-based measures and completed questionnaires were included in the analyses. To account for several observation days per participant multilevel regression analyses were applied. Analyses were stratified according to the time out-of-home (more or less than 100 min/day).

Results

In the group with less than 100 min out-of-home, each additional minute out-of-home added 20 s to overall walking duration. If the time exceeded 100 min the additional increase of walking duration was only moderate or weak. Leaving the home once added 40 min of walking, the following trips 15 to 20 min. Increasing age, lower gait speed, comorbidities, low temperature, rain and specific week days (Sunday) decreased both the time out-of-home and walking duration. Other variables like gender (female), isolation or living with a spouse reduced the time out-of-home without affecting walking duration.

Conclusions

Being out-of-home increases daily walking duration. The association is strongest if the time out-of-home is 100 min or less.

Children enter the crucial transition to school with sociodemographic disparities firmly established. Domain-specific research (e.g., on poverty and family structure) has shed light on these disparities, but we need broader operationalizations of children’s environments to explain them. Building on existing theory, this study articulates the concept of developmental ecology—those interrelated features of a child’s proximal environment that shape development and health. Developmental ecology links structural and demographic factors with interactional, psychological, and genetic factors. Using the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B), this study conducts latent class analyses to identify how 41 factors from three domains—namely, household resources, health risks, and ecological changes—cluster within children as four overarching developmental ecologies. Because it documents how numerous factors co-occur within children, this method allows an approximation of their lived environments. Findings illuminate powerful relationships between race/ethnicity, parental age, socioeconomic background, and nativity and a child’s developmental ecology, as well as associations between developmental ecology and kindergarten cognition, behavior, and health. Developmental ecology represents a major pathway through which demographic characteristics shape school readiness. Because specific factors have different implications depending on the ecologies in which they are embedded, findings support the usefulness of a broad ecological approach.  相似文献

Extensive research has found that marriage provides health benefits to individuals, particularly in the U.S. The rise of cohabitation, however, raises questions about whether simply being in an intimate co-residential partnership conveys the same health benefits as marriage. Here, we use OLS regression to compare differences between partnered and unpartnered, and cohabiting and married individuals with respect to self-rated health in mid-life, an understudied part of the lifecourse. We pay particular attention to selection mechanisms arising in childhood and characteristics of the partnership. We compare results in five countries with different social, economic, and policy contexts: the U.S. (NLSY), U.K. (UKHLS), Australia (HILDA), Germany (SOEP), and Norway (GGS). Results show that living with a partner is positively associated with self-rated health in mid-life in all countries, but that controlling for children, prior separation, and current socio-economic status eliminates differences in Germany and Norway. Significant differences between cohabitation and marriage are only evident in the U.S. and the U.K., but controlling for childhood background, union duration, and prior union dissolution eliminates partnership differentials. The findings suggest that cohabitation in the U.S. and U.K., both liberal welfare regimes, seems to be very different than in the other countries. The results challenge the assumption that only marriage is beneficial for health.  相似文献

Governmentality studies and social theories agree that in contemporary societies the idea of autonomy is no longer simply an ideal or an individual aspiration but a social obligation. In an attempt to clarify the meaning of autonomy in this day and age, this paper asks how individuals perceive and negotiate the various dimensions of autonomy and how this affects the functioning of late-modern institutions. The empirical insights derived from a qualitative study provide a differentiated picture of how individuals pursue their claims to autonomy and comply with institutional demands for autonomy in everyday practice. By presenting seven types of late-modern “autonomy managers,” the analysis evinces a usurpation of autonomous agency that renders individuals the institutional editors of the contemporary contradictions, deficits, and tensions that occur in their everyday interactions. This comes at the price of notionally free but exhausted actors running short of all kinds of resources.  相似文献

Using the National Longitudinal Study of Adolescent Health, factors associated with incongruence between parents' and adolescents' reports of teens' sexual experience were investigated, and the consequences of inaccurate parental knowledge for adolescents' subsequent sexual behaviors were explored. Most parents of virgins accurately reported teens' lack of experience, but most parents of teens who had had sex provided inaccurate reports. Binary logistic regression analyses showed that many adolescent-, parent-, and family-level factors predicted the accuracy of parents' reports. Parents' accurate knowledge of their teens' sexual experience was not found to be consistently beneficial for teens' subsequent sexual outcomes. Rather, parents' expectations about teens' sexual experience created a self-fulfilling prophecy, with teens' subsequent sexual outcomes conforming to parents' expectations. These findings suggest that research on parent–teen communication about sex needs to consider the expectations being expressed, as well as the information being exchanged.  相似文献

While Tee Corinne has been widely recognized as a preeminent lesbian and feminist artist of the last forty years, little has been written about her as an artist or art historian in any substantial way. This article attempts to shed light on Corinne's investment in creating explicitly sexual lesbian visual art and art historical writings that put pressure on the categories of artist and art historian between the 1970s and early 2000s. Corinne's work manages to fulfill feminist ideals while also working outside of the norms set up in both the lesbian and mainstream realms of art and art history.  相似文献

Several significant changes in the diagnostic criteria for gambling disorder occurred with the newest revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The changes aim to simplify and streamline the diagnosis without compromising its validity. Yet many of the tools used to screen and diagnose the disorder are based upon the prior fourth edition of the DSM, and it is unclear how they perform with the revised diagnostic criteria. The aim of this study is to examine the psychometric properties of a common pathological gambling screen, the Brief Biosocial Gambling Screen (BBGS; Gebauer, LaBrie, & Shaffer, 2010), in the context of DSM-5 criteria within a help-seeking sample. Gamblers calling a helpline (N = 2750) completed a semi-structured interview assessing DSM-IV past-year pathological gambling criteria with a trained clinician. Sensitivity, specificity, positive predictive value, negative predictive value and differences by sex were examined. The BBGS had high sensitivity as well as positive and negative predictive values. In light of the revisions made to the diagnostic criteria in DSM-5, the BBGS remains a psychometrically supported instrument for gambling disorder.  相似文献
