Although studies examine preferences for hours spent in paid employment, little attention has been given to preferences for hours spent in unpaid household labor. This study examines the extent to which women working in low‐paid retail jobs would prefer to spend more or less time on household work and how alignment between preferred and actual time on housework is related to characteristics of paid work. Using original survey data and company records on a sample of women working at a U.S. retail firm (N = 277), the authors found that mismatch between preferred and actual time on household work was common. Roughly 42% wanted more time on household work and 18% wanted less. Working multiple jobs, work schedule unpredictability, and nonstandard work timing contributed to wanting more time on housework. Findings add to understanding of how low‐wage, precarious employment shapes workers' ability to attend to necessary tasks of household management. 相似文献

The accessibility and ubiquity of zoos and aquariums—which reach over 700 million people worldwide annually—make them critical sites for science and environmental learning. Through educational offerings, these sites can generate excitement and curiosity about nature and motivate stewardship behavior, but only if their programs are high quality and meet the needs of their audiences. Evaluation is, therefore, critical: knowing what works, for whom, and under what conditions must be central to these organizations. Yet, many zoo and aquarium educators find evaluation to be daunting, and they are challenged to implement evaluations and/or use the findings iteratively in program development and improvement. This article examines how zoo education professionals engage with one another in a learning community related to evaluation. We use a communities of practice lens and social network analysis to understand the structure of this networked learning community, considering changes over time. Our findings suggest that individuals’ roles in a networked learning community are influenced by factors such as communicative convenience and one’s perceptions of others’ evaluation expertise, which also contribute to forming and sustaining professional relationships. This study illuminates how project-based professional networks can become communities of practice. 相似文献

AbstractThis paper intends to address the challenges that the Italian education system is facing in terms of policies and practices relating to dis/abled asylum-seeking and refugee children, in order to make sense of the politics of daily life inside schools and the network of social services for forced migrants, and to pay renewed attention to the notion of ‘social and educational integration’. The starting point of this paper is the idea that the current model of schooling for asylum-seeking and refugee children is implicated in the making of particular sorts of ‘subjects’, as well as the creation of educational and social exclusions and inequalities. Schools, refugee organisations as well as the work of educators and social workers can be important sites of ‘counter-politics’. Borrowing from the theoretical tools offered by Dis/Ability Critical Race Studies (Dis/Crit) framework and engaging with Judith Butler’s understanding of processes of subjectivation, the paper explores how asylum-seeking and refugee students can be rendered subjects outside the educational endeavour, or indeed outside studenthood. Data from an ongoing constructivist grounded theory doctoral research project, interviews with asylum-seeking children and with professionals working in different refugee services in Rome, are offered to substantiate the argument presented in this paper. 相似文献

ABSTRACTSexual minorities are receiving an increasing amount of attention within sociological research on families. However, much of the existing work on these families has been limited to largely White, middle-class, and highly educated individuals. Using national data from the Social Justice Sexuality Project, this study fills a much-needed gap by exploring predictors of family support and the relationship between family support and well-being among Black and Latina/o sexual minorities. We find that sexual identity, how out one is to one's family, and relationship status predict levels of family support. In addition, we find that among Black and Latina/o individuals, family support is an important factor influencing health and well-being. Other social statuses such as gender identity, sexual identity, and relationship status are associated with happiness and self-rated health as well. Our work suggests that sexual minorities of color have unique family dynamics that should be studied from an intersectional perspective. Further investigation into the family dynamics of sexual minorities of color should pay particular attention to individuals' positionality within systems of gender, racial, and sexual identity disadvantage to help understand their health and well-being. 相似文献

Traditional resampling methods for estimating sampling distributions sometimes fail, and alternative approaches are then needed. For example, if the classical central limit theorem does not hold and the naïve bootstrap fails, the m/n bootstrap, based on smaller-sized resamples, may be used as an alternative. An alternative to the naïve bootstrap, the sufficient bootstrap, which uses only the distinct observations in a bootstrap sample, is another recently proposed bootstrap approach that has been suggested to reduce the computational burden associated with bootstrapping. It works as long as naïve bootstrap does. However, if the naïve bootstrap fails, so will the sufficient bootstrap. In this paper, we propose combining the sufficient bootstrap with the m/n bootstrap in order to both regain consistent estimation of sampling distributions and to reduce the computational burden of the bootstrap. We obtain necessary and sufficient conditions for asymptotic normality of the proposed method, and propose new values for the resample size m. We compare the proposed method with the naïve bootstrap, the sufficient bootstrap, and the m/n bootstrap by simulation. 相似文献

In this article, a non-iterative sampling algorithm is developed to obtain an independently and identically distributed samples approximately from the posterior distribution of parameters in Laplace linear regression model. By combining the inverse Bayes formulae, sampling/importance resampling, and expectation maximum algorithm, the algorithm eliminates the diagnosis of convergence in the iterative Gibbs sampling and the samples generated from it can be used for inferences immediately. Simulations are conducted to illustrate the robustness and effectiveness of the algorithm. Finally, real data are studied to show the usefulness of the proposed methodology. 相似文献

Childhood adversity,adult homelessness and the intergenerational transmission of risk: a population‐representative study of individuals in households with children 下载免费PDF全文

This study tested for associations between childhood adversity, adult homelessness and contexts of developmental risk in households with children. Data were drawn from the 2010 Washington State Behavioral Risk Factor Surveillance System, representative of the population of Washington State residents. Considering adults in households with children, those who experienced higher levels of childhood adversity were more likely to have experienced homelessness in adulthood. Meanwhile, a 10‐factor index of cumulative developmental risk was independently associated with childhood adversity and with adult homelessness. Adult homelessness appears to represent a circumstance through which past childhood adversities are brought forward and associated with contexts of developmental risk for subsequent generations of children. 相似文献

While there is a growing body of work on using fatherhood as an opportunity to engage men in strategies to prevent child maltreatment and further acts of domestic violence, there is limited research on engaging fathers in strategies to prevent domestic violence from occurring. To fill this gap in the literature, this paper explores existing father engagement frameworks used in child and family services and supports a multi‐level model of father engagement for domestic violence primary prevention. Drawing together evidence about father engagement from a range of studies, including the more general parenting literature, we describe factors that influence father engagement based on an analysis of the literature. These factors include accessibility, staff attitudes and behaviours, programme marketing and the format of service provision. 相似文献
