Disasters result in devastating human, economic, and environmental effects. The paper highlights women's active participation in community-based disaster recovery efforts drawing from the results of the ‘Rebuilding Lives Post-disaster: Innovative Community Practices for Sustainable Development’ by an international research partnership. Two case studies are presented from Pakistan and the USA to demonstrate how women contribute to building resilience and promoting sustainable development in diverse post-disaster contexts. The policy and practice implications are relevant for discussions regarding the post-2015 Sustainable Development Goals and framework.  相似文献

Drawing from problem behavior theory (PBT), this study investigates whether the relationship between exposure to delinquent peers and delinquent behavior is moderated by peer influences as well as by generalized self-efficacy and an adolescent's attitudes toward deviance. We also explore how gender may influence these relationships. A sample of 401 African-American adolescents living in public housing developments in two large US cities was recruited for this investigation. The preliminary analyses included t-test and bivariate correlations, while our primary analysis included hierarchical regression analysis. The regression analysis included two-way and three-way interaction terms to assess the moderating effects of peer influences, generalized self-efficacy, and attitudes toward deviance as well as gender, respectively. Results indicate that the effects of exposure to delinquent peers depend on peers' influence over adolescents and other factors. Findings provide partial support for PBT and suggest that the relationship between exposure to delinquent peers and delinquent behavior, with regard to minority youth living in urban public housing, merits further investigation. Results have the potential to guide preventative interventions targeting African-American youth living in urban public housing and also inform future inquiries into the lives of such youth.  相似文献

Task shifting, which involves the transfer of care work from regulated health‐care professionals to home care workers (HCWs), is a strategy to ensure the efficient delivery of home care services in Canada and internationally. Using a feminist political economy approach, this paper explores the effects of task shifting on HCWs’ skills. Task shifting may be understood as a form of downward substitution—and an effort to increase control over workers while minimizing costs—as some of health‐care professionals’ responsibilities are divided into simpler tasks and transferred to HCWs. Our interviews with 46 home health‐care providers in Ontario, which focused explicitly on HCWs’ role in care provision, problematize the belief that “low skilled” care workers have little control over their work. HCWs’ skills become more complex when they do transferred tasks, and HCWs sometimes gain greater control over their work. This results in increased autonomy and mastery for many HCWs. In turn, this serves to reinforce the intrinsic rewards of care work, despite the fact that it is low paid and undervalued work. Le transfert des tâches consiste à transférer certaines activités des professionnels de la santé aux travailleurs de soutien à domicile, et s'avère être une stratégie visant à assurer la prestation efficace des services de soutien à domicile au Canada et à l'étranger. En utilisant la théorie de l'économie politique féministe, cet article explore l'impact du transfert des tâches sur les compétences des travailleurs de soutien à domicile. Le transfert des tâches peut être interprété comme une forme de substitution à la baisse avec un contrôle accru des travailleurs et une minimisation des coûts des services. Ceci se produit lorsque certaines des responsabilités des professionnels de la santé sont fragmentées en tâches plus simples pour être ensuite transférées aux travailleurs de soutien à domicile. Pourtant, le contenu de 46 entrevues avec des travailleurs de soutien à domicile et professionnels de la santé vient ébranler l'hypothèse selon laquelle les travailleurs de soutien à domicile «peu qualifiés» auraient peu de contrôle sur leurs tâches de travail. Les résultats de cette étude suggèrent que les compétences des travailleurs de soutien à domicile se complexifient lorsqu'il s'agit de tâches transférées, et que ces travailleurs obtiennent parfois plus d'autonomie à l'emploi. Donc, les travailleurs de soutien à domicile acquièrent une plus grande autonomie et un contrôle plus significatif à l'emploi. Par conséquent, le transfert des tâches renforce les gratifications intrinsèques du travail en relation d'aide et ce, en dépit d'une piètre rémunération et de la sous‐valorisation du métier.  相似文献

The U.S. Environmental Protection Agency's (EPA) Integrated Risk Information System (IRIS) database, the authoritative source of U.S. risk assessment toxicity factors, currently lacks an oral reference dose (RfD) for copper. In the absence of such a value, various health-based reference values for copper are available for use in risk assessment. We summarize the scientific bases and differences in assumptions among key reference values for ingested copper to guide selection of appropriate values for risk assessment. A comprehensive review of the scientific literature best supports the oral RfD of 0.04 mg/kg body weight/day derived by EPA from their Drinking Water Action Level. This value is based on acute gastrointestinal effects but is further supported by broader analysis of copper deficiency and toxicity.  相似文献

Although parent ratings, adolescent ratings, and observations are all utilized to measure parent emotion socialization during adolescence, there is a lack of research examining measurement differences and concordance. Thus, the present study compared three measures of parent supportive and nonsupportive emotion socialization and examined whether parent and adolescent emotion dysregulation differentially related to these measures or moderated concordance across measures. Participants were a community sample of 92 adolescent-parent dyads. Adolescents were 13–17 years-old (M = 15.5, SD = 1.1), 41 were female and 51 were male; 87% of parents identified as mothers. Observed emotion socialization was coded during a parent-adolescent conflict discussion task. The adolescent and parent also rated the parent's supportive and nonsupportive reactions to the adolescent's negative emotions; they each also rated their own emotion dysregulation. Due to data collection timing, COVID-19 family stress was also assessed and explored as a covariate in analyses. Bivariate correlations indicated that there were weak and non-significant correlations across emotion socialization measures. Multilevel models indicated that measures of parent emotion socialization were differentially associated with adolescent emotion dysregulation, with adolescent emotion dysregulation relating significantly to adolescent ratings, but not observations or parent ratings, of parent emotion socialization. In addition, multiple regressions indicated that there was less concordance across measures when parents were higher in emotion dysregulation. Results suggest that measurement may influence researchers’ conclusions about how youth adjustment relates to parent emotion socialization. Additionally, there may be even lower agreement across measures of parent emotion socialization when parents have emotional challenges.  相似文献

Generic accounts of pervasive cases of exploitation and abuse against migrant domestic workers in the Middle East exist in the extant literature. However, very little is known about the breadth, depth and gendered nature of abuses experienced by female migrants from especially the sub-Saharan African region. Abuses of the rights of sub-Saharan Africans are under-represented and under-theorised. This paper interrogates the question what is the nature, extent and severity of exploitation and abuse against female Ghanaian domestic workers in the Middle East? Using data from mixed-methods research, this paper adopts the framework of structural, symbolic and interpersonal violence to examine the range of abuses against domestic workers and the context within which these abuses take place.  相似文献

Conventional analyses of a composite of multiple time-to-event outcomes use the time to the first event. However, the first event may not be the most important outcome. To address this limitation, generalized pairwise comparisons and win statistics (win ratio, win odds, and net benefit) have become popular and have been applied to clinical trial practice. However, win ratio, win odds, and net benefit have typically been used separately. In this article, we examine the use of these three win statistics jointly for time-to-event outcomes. First, we explain the relation of point estimates and variances among the three win statistics, and the relation between the net benefit and the Mann–Whitney U statistic. Then we explain that the three win statistics are based on the same win proportions, and they test the same null hypothesis of equal win probabilities in two groups. We show theoretically that the Z-values of the corresponding statistical tests are approximately equal; therefore, the three win statistics provide very similar p-values and statistical powers. Finally, using simulation studies and data from a clinical trial, we demonstrate that, when there is no (or little) censoring, the three win statistics can complement one another to show the strength of the treatment effect. However, when the amount of censoring is not small, and without adjustment for censoring, the win odds and the net benefit may have an advantage for interpreting the treatment effect; with adjustment (e.g., IPCW adjustment) for censoring, the three win statistics can complement one another to show the strength of the treatment effect. For calculations we use the R package WINS, available on the CRAN (Comprehensive R Archive Network).  相似文献

We hypothesized that the goodness-of-fit between profiles of observed, caregiver-provided ethnic–racial socialization (ERS), and child self-regulation (i.e., inhibitory control) would differentially associate with child behavioral outcomes. Conversations between 80 caregivers (45% Latinx; 55% Black) and their children (M age  = 11.09; 46% female) were rated for ERS. Measures included an inhibitory control composite (ages 2.5–3.5) and the Child Behavior Checklist (CBCL; age 12). Three profiles were determined: Comprehensive (n  = 34), Reactive (n  = 8), and Pragmatic (n  = 38). Only youth with low inhibitory control in preschool appeared to benefit from Pragmatic ERS, whereas youth with normative or high inhibitory control in early childhood displayed lower internalizing and externalizing behaviors when they had Comprehensive or Reactive rather than Pragmatic caregivers.  相似文献
