In this paper, we test the hypothesis that unique effects of stepfamily composition on union fertility are confounded with differences between stepfamilies and couples without stepchildren in the risk of union disruption. We use birth and union histories from Fertility and Family Surveys in Austria, Finland, France and West Germany. The risks of a union birth and separation are modeled simultaneously, allowing for the potential effects of unobserved predispositions to have a child or to separate on the other event. We test hypotheses drawn from the value of first and second shared births to couples: Net of the couple’s combined parity, the birth risk will be greater if the child is (a) the first in a union, (b) the first biological child for one of the partners, or (c) the second child in a union.Henz, U. et Thomson, E., 2005.

This study identifies the conceptual underpinnings of effective school-based drug education practice in light of contemporary research evidence and the practical experience of a broad range of drug education stakeholders. The research involved a review of the literature, a national survey of 210 Australian teachers and others involved in drug education, and structured interviews with 22 key Australian drug education policy stakeholders. The findings from this research have been distilled and presented as a list of 16 principles that underpin effective drug education. In broad terms, drug education should be evidence-based, developmentally appropriate, sequential, and contextual. Programs should be initiated before drug use commences. Strategies should be linked to goals and should incorporate harm minimization. Teaching should be interactive and use peer leaders. The role of the classroom teacher is central. Certain program content is important, as is social and resistance skills training. Community values, the social context of use, and the nature of drug harm have to be addressed. Coverage needs to be adequate and supported by follow-up. It is envisaged that these principles will provide all those involved in the drug education field with a set of up-to-date, research-based guidelines against which to reference decisions on program design, selection, implementation, and evaluation. 相似文献

This article analyzes forms and enabling practices of expatriate mobility, i. e. the mobility of managers and skilled professionals assigned to a foreign subsidiary of their company. We will show that (1) expatriate mobility has to be conceived of as complex entangled mobilities that add up to a hyper-mobility, and (2) that this hyper-mobility inevitably depends on the active mobility work of the expatriates’ ‘trailing spouses’. Thus, it becomes clear that the mobility management on which expatriate mobility depends is highly gendered. By focusing on the specifics of expatriate mobility, the article also opens up new theoretical perspectives for mobility research in general. 相似文献

Physical activity offers one of the greatest opportunities for people to extend years of active independent life and reduce functional limitations. The purpose of this paper is to identify key practices for promoting physical activity in older adults, with a focus on older adults with chronic disease or low fitness and those with low levels of physical activity. Key practices identified in promotion activity in older adults include: (1) a multidimensional activity program that includes endurance, strength, balance, and flexibility training is optimal for health and functional benefits; (2) principles of behavior change, including social support, self-efficacy, active choices, health contracts, assurances of safety, and positive reinforcement, enhance adherence; (3) management of risk by beginning at low intensity but gradually increasing to moderate physical activity which has a better risk/benefit ratio should be the goal for older adults; (4) an emergency procedure plan is prudent for community-based programs; and (5) monitoring aerobic intensity is important for progression and for motivation. Selected content reviews of physical activity programming from major organizations and institutions are provided. Regular participation in physical activity is one of the most effective ways for older adults, including those with disabilities, to help prevent chronic disease, promote independence, and increase quality of life in old age.Publication Note All National Blueprint Publications are in the public domain and can be freely reproduced without copyright.

This study investigated three dimensions of sexual orientation—identity, attraction, and behavior—in a national survey of late adolescents. Prevalence rates and the diversity of dimensions of sexual orientation when combined were studied. A representative sample of 3,432 Swedish high school seniors completed an anonymous school-based self-report survey about sexuality, Internet use, and health. Four measures of sexual orientation were included—one for sexual identity, two for attraction (emotional or sexual attraction, romantic attraction), and one for sexual behavior. Prevalence rates of sexual minority orientation varied between 4.3% for sexual behavior (males 2.9%, females 5.6%) and 29.4% for emotional or sexual attraction (males 17.7%, females 39.5%). Different measures of sexual orientation were significantly associated with one another. Bisexual or homosexual orientation was reported by 1.5% of the participants in all four measures and by 17.6% in at least one measure. Researchers need to carefully choose, depending on the research questions under investigation, which dimensions of sexual orientation and which measures they wish to include in their survey. Recommendations based on findings from the study are given. 相似文献

The present research aims to assess how occupational stereotypes, and in particular, stereotypes about doctors, influence the observers’ perception of the emotions expressed by members of this group. For this, 60 men and women judged the emotions of women who expressed either happiness, anger, sadness, or a neutral expression and whose faces were either uncovered or covered with a surgical mask, a niqab, or a hat and scarf such that only an identical portion of the face around the eyes was visible. Congruent with the occupational stereotype, women dressed as doctors were perceived highest on competence and warmth, but also as emotionally restrained such that they were rated as experiencing lower levels of emotions relative to the same women wearing other face covers or with uncovered faces. 相似文献
