Sober living houses (SLHs) are alcohol and drug‐free living environments for individuals in recovery. The goal of this study was to map the distribution of SLHs in Los Angeles (LA) County, California (N = 260) and examine neighborhood correlates of SLH density. Locations of SLHs were geocoded and linked to tract‐level Census data as well as to publicly available information on alcohol outlets and recovery resources. Neighborhoods with SLHs differed from neighborhoods without them on measures of socioeconomic disadvantage and accessibility of recovery resources. In multivariate, spatially lagged hurdle models stratified by monthly fees charged (less than $1400/month vs. $1400/month or greater), minority composition, and accessibility of treatment were associated with the presence of affordable SLHs. Accessibility of treatment was also associated with the number of affordable SLHs in those neighborhoods. Higher median housing value and accessibility of treatment were associated with whether a neighborhood had high‐cost SLHs, and lower population density was associated with the number of high‐cost SLHs in those neighborhoods. Neighborhood factors are associated with the availability of SLHs, and research is needed to better understand how these factors affect resident outcomes, as well as how SLHs may affect neighborhoods over time.  相似文献

Gender refers to ways men and women socialize into the male and female roles that are commonly attributed to them. These roles are continuously (re)constructed within and through our daily activities. Prior literature suggests a need for more research in investigating how men and women construct their identity in various exchange situations and in various cultural settings. This paper explores the situational construction of male and female identities (especially the male one) when shopping for fashion products in environments with strategically created scarcity. The findings of this study suggest that, when shopping for fashion products in scarce environments, men and women tend to exhibit gendered behaviors that are considered more consistent with their traditional gender norms. We find that men, although concerned about their appearance, adhere to urgent buying behavior. This behavior helps men maintain some of their traditional masculine identity. In addition, they do not participate as frequently in the in‐store hoarding and in‐store hiding that are more frequently exhibited by women and that are more consistent with a feminine identity.

Rule‐guided behavior depends on the ability to strategically update and act on content held in working memory. Proactive and reactive control strategies were contrasted across two experiments using an adapted input/output gating paradigm (Neuron, 81, 2014 and 930). Behavioral accuracies of 3‐, 5‐, and 7‐year‐olds were higher when a contextual cue appeared at the beginning of the task (input gating) rather than at the end (output gating). This finding supports prior work in older children, suggesting that children are better when input gating but rely on the more effortful output gating strategy for goal‐oriented action selection (Cognition, 155, 2016 and 8). A manipulation was added to investigate whether children's use of working memory strategies becomes more flexible when task goals are specified internally rather than externally provided by the experimenter. A shift toward more proactive control was observed when children chose the task goal among two alternatives. Scan path analyses of saccadic eye movement indicated that giving children agency and choice over the task goal resulted in less use of a reactive strategy than when the goal was determined by the experimenter.  相似文献

The present work investigated the prevalence and spectrum of psychopathology in children with thalassemia. Childhood psychopathology measurement schedule (CPMS), adapted from Child Behavior Checklist was administered on children with thalassemia major receiving regular blood transfusion. Age and sex matched children with other chronic illness (bronchial asthma) served as controls. 46.7% of children with thalassemia had a CPMS score of > 10 as against 17.1% in the control group. Children with thalassemia had higher scores in factors of conduct problems, special symptoms and somatization. This study highlights the significantly higher psychopathology in children with thalassemia major and emphasizes the need for psychosocial support during treatment.  相似文献

Knowledge about dimensionality of Organizational Citizenship Behavior (OCB) is essential for conducting any future research on the construct. The present study explores the suitability of OCB conceptualization developed by Organ (1988) in Indian business context. Confirmatory Factor Analysis (CFA) was performed to test the dimensionality of the 5-factor OCB conceptualization. Based on the results of CFA alternate conceptualizations were explored. A three factor conceptualization consisting of ??organization-orientation??, ??punctuality?? and ??individual-orientation?? factors showed excellent fit with data. Concurrent validity of factors was tested with organizational justice, organizational identification and job tenure. ??Organization-orientation?? and ??individual-orientation?? emerged as significant dimensions of OCB. Implications for theory and practice are discussed.  相似文献

In piezoelectric nanocomposites, surface/interface plays an important role in determining the size-dependent behavior of media. Within the framework of couple stress, the effect of surface/interface around a nano-hole on the anti-plane electro-mechanical behavior is examined. By introducing a surface/interface model, the stress and electric displacement effects on the size-dependent behavior are both considered. The governing equations in piezoelectric materials are decoupled into the classical ones. The displacement and electric potential are expressed by Bessel functions. By satisfying the boundary conditions around the hole with the interface/surface effect, the expanded coefficients are obtained. Through analysis, it is shown that the mechanical and electrical fields drastically depend on the relative size of the hole with respect to the characteristic length of the material. The effects of couple stresses on the stress and electric field are also addressed. Comparison with the existing results is also given.  相似文献

This longitudinal study of 286, urban residing, first- and second-generation immigrant adolescents examined the degree to which acculturative stress is related to the developmental trajectories of mental health problems and the role of social support in this process. Participants were recruited when they entered 10th grade and two additional waves of data were gathered at 12-month intervals. Using individual growth curve modeling, the results show significant decline in internalizing mental health problems during the high school years. At the same time, greater exposure to acculturative stress predicted significantly more withdrawn/depressed, somatic, and anxious/depressed symptoms. Additionally, social support moderated the relation between acculturative stress and anxious/depressed symptoms. Gender and generation status differences were found only at baseline (10th grade).  相似文献

Maternal smoking and depressive symptoms are independently linked to poor child health outcomes. However, little is known about factors that may predict maternal depressive symptoms among low-income, African American maternal smokers—an understudied population with children known to have increased morbidity and mortality risks. The objective of this study was to test the hypothesis that secondhand smoke exposure (SHSe)-related pediatric sick visits are associated with significant maternal depressive symptoms among low-income, African American maternal smokers in the context of other depression-related factors. Prior to randomization in a behavioral counseling trial to reduce child SHSe, 307 maternal smokers in Philadelphia completed the Center for Epidemiologic Studies Depression (CES-D) and questionnaires measuring stressful events, nicotine dependence, social support, child health and demographics. CES-D was dichotomized at the clinical cutoff to differentiate mothers with significant versus low depressive symptoms. Results from direct entry logistic regression demonstrated that maternal smokers reporting more than one SHSe-related sick visit (OR 1.38, p < .001), greater perceived life stress (OR 1.05, p < .001) and less social support (OR 0.82, p < .001) within the last 3 months were more likely to report significant depressive symptoms than mothers with fewer clinic visits, less stress, and greater social support. These results suggest opportunities for future hypothesis-driven evaluation, and exploration of intervention strategies in pediatric primary care. Maternal depression, smoking and child illness may present as a reciprocally-determined phenomenon that points to the potential utility of treating one chronic maternal condition to facilitate change in the other chronic condition, regardless of which primary presenting problem is addressed. Future longitudinal research could attempt to confirm this hypothesis.  相似文献

Prior research has demonstrated deficits in defensive reactivity (indexed by potentiation of the startle blink reflex) in psychopathic individuals. However, the basis of this association remains unclear, as diagnostic criteria for psychopathy encompass two distinct phenotypic components that may reflect differing neurobiological mechanisms-an affective-interpersonal component and an antisocial deviance component. Likewise, the role of defensive response deficits in antisocial personality disorder (APD), a related but distinct syndrome, remains to be clarified. In the current study, the authors examined affective priming deficits in relation to factors of psychopathy and symptoms of APD using startle reflex methods in 108 adult male prisoners. Deficits in blink reflex potentiation during aversive picture viewing were found in relation to the affective-interpersonal (Factor 1) component of psychopathy, and to a lesser extent in relation to the antisocial deviance (Factor 2) component of psychopathy and symptoms of APD-but only as a function of their overlap with affective-interpersonal features of psychopathy. These findings provide clear evidence that deficits in defensive reactivity are linked specifically to the affective-interpersonal features of psychopathy and not to the antisocial deviance features represented most strongly in APD.  相似文献
