Two studies investigated the delay discounting effect in charitable giving situations, and whether construal level moderates this effect. In both studies, construal level was manipulated by inducing a concrete vs. an abstract mindset. Participants were asked how much time (Experiment 1) or how much money (Experiment 2) they would be willing to volunteer or donate, respectively, to a self-chosen charitable organization in either the near or distant future. Participants committed themselves to contributing more time and money in the distant than in the near future. Additionally, an abstract (vs. concrete) mindset reduced this delay discounting effect, particularly for monetary donations. Delay discounting of costs associated with altruistic behavior and the role of construal level in increasing donations and volunteering are discussed. 相似文献

The current study investigated the relationship between mother–child interaction quality and infants' ability to interpret actions as goal‐directed at 7 months in a sample of 37 dyads. Interaction quality was assessed in a free play interaction using two distinct methods: one assessed the overall affective quality (emotional availability), and one focused on the mother's proclivity to treat her infant as an intentional agent (mind‐mindedness). Furthermore, infants' ability to interpret human actions as goal‐directed was assessed. Analyses revealed that only maternal emotional availability, and not maternal mind‐mindedness, was related to infants' goal‐encoding ability. This link remained stable even when controlling for child temperament, working memory, and maternal education. These findings provide first evidence that emotionally available caregiving promotes social‐cognitive development in preverbal infants. 相似文献

Developing an identity as mother and establishing what it means to mother is a task not defined by sexual orientation. Both heterosexual and homosexual women encounter role models and the dictates of society when mothering (Nelson, 1996). The present study explores how 18 lesbian adoptive parents, 49 lesbian parents who formed their families biologically, and 44 heterosexual adoptive parents experience and perceive their parenting role, how they respond when their children seek them or their partner for particular nurturing, and how the parents negotiate the cultural expectation of a primary caregiver. Lesbian couples were more equal in their division of childcare than heterosexual parents, and lesbian adoptive parents were the most egalitarian. In all types of dual parent families, parents were sought by their child for different activities. In heterosexual adoptive and lesbian biological families, the child's parental preference was rarely a source of conflict between partners. Lesbian adoptive parents were more likely to report that this preference caused occasional conflict. Reasons for this conflict are discussed in light of societal expectations of women and the role of mother. 相似文献

This paper examines gendered housework in the larger context of comparative social change, asking specifically whether cross‐national differences in domestic labor patterns converge over time. Our analysis of data from 13 countries (N = 11,065) from the 1994 and 2002 International Social Survey Program (ISSP) confirmed that social context matters in shaping couples' division of labor at home, but also showed that context affects patterns of change. Our results suggested that, compared to the most egalitarian countries, the shift in housework patterns was greatest among the most traditional countries. This provides support for the thesis of cultural convergence, but the evidence did not suggest that such convergence will lead to complete equality in the foreseeable future. 相似文献

Because they often set out with a guarantee of only short-term funding, many community partnerships will face a threat to their sustainability almost as soon as the first money runs out. Research into the factors that enable some coalitions and partnerships to meet the challenge when others fail is limited. This study begins to fill this gap in our understanding by examining influences on the process of sustainability planning in the context of a collaborative partnership focused on youth development. We report on a longitudinal examination of the quality of planning and attitudes underpinning the sustainability of PROSPER community prevention teams whose members implement evidence-based programs designed to support positive youth development and reduce early substance use and other problem behaviors. The current research concentrates on a particular dimension of partnership effectiveness to establish whether perceptions about team functioning in play at 6 and 18 months predict the quality of sustainability planning at 36 and 48 months. How well teams functioned in the early stages was found to be strongly related to the quality of their later preparations for sustainability. Recruitment and integration of new team members, and the encouragement they subsequently received were also found to be key factors. The results strengthen the argument for providing technical assistance to meet the needs of those who promote prevention partnerships, and they provide longitudinal empirical data to support the hypotheses of other researchers who have similarly found a correlation between effective sustainability and early planning and support. 相似文献

The determinants of the decision to naturalize for first and second generation “labor migrants” in Germany are examined. We assume that Turkish migrants' comparatively high naturalization rate cannot be explained by the legal advantages they gain by naturalizing. We argue instead that naturalization offers an opportunity for individual upward mobility to Turkish migrants who have achieved a high level of individual assimilation. Using data from the GSOEP, we show that individual assimilation does in fact promote naturalization for Turkish migrants, but not for members of other ethnic groups, which generally have higher status within German society. 相似文献

Summary. We analyse data from a seroincident cohort of 457 homosexual men who were infected with the human immunodeficiency virus, followed within the multicentre Italian Seroconversion Study. These data include onset times to acquired immune deficiency syndrome (AIDS), longitudinal measurements of CD4+ T-cell counts taken on each subject during the AIDS-free period of observation and the period of administration of a highly active antiretro- viral therapy (HAART), for the subset of individuals who received it. The aim of the study is to assess the effect of HAART on the course of the disease. We analyse the data by a Bayesian model in which the sequence of longitudinal CD4+ cell count observations and the associated time to AIDS are jointly modelled at an individual subject's level as depending on the treatment. We discuss the inferences obtained about the efficacy of HAART, as well as modelling and computation difficulties that were encountered in the analysis. These latter motivate a model criticism stage of the analysis, in which the model specification of CD4+ cell count progression and of the effect of treatment are checked. Our approach to model criticism is based on the notion of a counterfactual replicate data set Z c . This is a data set with the same shape and size as the observed data, which we might have observed by rerunning the study in exactly the same conditions as the actual study if the treated patients had not been treated at all. We draw samples of Z c from a null model M 0 , which assumes absence of treatment effect, conditioning on data collected in each subject before initiation of treatment. Model checking is performed by comparing the observed data with a set of samples of Z c drawn from M 0 . 相似文献

Cohesion and Enmeshment Revisited: Differentiation,Identity, and Well‐Being in Two European Cultures
Claudia Manzi Vivian L. Vignoles Camillo Regalia Eugenia Scabini 《Journal of marriage and the family》2006,68(3):673-689
We examined the nature and implications of family differentiation among adolescents facing a life transition in 2 European countries with differing family cultures. One hundred and twenty‐four Italian and 109 U.K. adolescents completed measures of family differentiation (cohesion and enmeshment), identity threat (perception of threat to the self associated with finishing school), life satisfaction, depressive symptoms, and anxiety. Confirmatory factor analyses showed that cohesion and enmeshment were distinguishable in both countries, orthogonal in the U.K. but positively correlated in Italy. Family cohesion was associated with better psychological well‐being in both countries; enmeshment was associated with poorer psychological well‐being in the U.K. but not in Italy. Structural equation models showed that effects on well‐being were fully mediated by identity threat in both cultures. 相似文献
