Although research has documented the majority of homelessness experienced by individuals and families in the US to be transitional rather than chronic, the mechanisms by which some families successfully escape homelessness while other do not remains relatively unclear. To provide more information to this area of inquiry, this study analyzed the transitional nature of homelessness for a sample of families with school-aged children who were homeless under the McKinney-Vento definition. By conducting a survey with over 1000 homeless families with children enrolled in two public school systems in Central Florida, we find that over a quarter of families exit homelessness in less than six months. We compare these families to those that remained homeless to examine the potential importance of demographic differences and other potential barriers to securing housing. Many of the commonly assumed barriers were not significant predictors of continued homelessness; the most salient difference between the groups was income underscoring the importance of employment opportunities for families to allow them to exit homelessness.  相似文献

This paper explores how gender ideologies shape industrial relations in the Asian garment industry. Drawing on ethnographic research, it illustrates how widespread norm perceptions of acquiescent women and assertive men reinforce patriarchal, authoritarian unions. Even if privately critical, women may be reluctant to protest if they anticipate social disapproval. Such beliefs reinforce patriarchal unions, curbing women workers’ collective analysis, engagement, and activism. This weakens the collective power of labour to push for better working conditions. Tackling norm perceptions and building more inclusive unions may help strengthen the labour movement.  相似文献

This study investigated the association between risky sexual behavior and drug use among female youth sentenced to a regional juvenile detention center. Preincarceration behavioral health risk data were collected from a modified version of the Youth Risk Behaviors Surveillance Survey completed by respondents. Almost all of the 105 participants had been detained before their current sentence, more than half of them were sexually active before the age of 13, and 70% had smoked marijuana or drank alcohol by age 14. A regression analysis was conducted to determine if preincarceration sexual health risk behaviors were significant enough to predict continued risk behaviors related to pregnancy, disease prevention, and substance use. Findings indicate that youth detention-based prevention programs should emphasize sexual and drug-risk reduction strategies as a means to reduce risky behaviors for this population.  相似文献

ABSTRACT

For decades Hip Hop cultural practices have been disparaged for allegedly inciting and being responsible for the eruption of urban violence. This assumption, likely built upon pre-existing biases regarding the street culture and ethnic minorities where Hip Hop emerged, ignored how some of the genre’s main elements – particularly freestyle rap, breakin’ or breakdancing and graffiti tagging – initially served the purpose of providing at-risk youths with real alternatives to direct physical violence in their day-to-day lives, and continue do so today. It has also ignored broader analogies with other cross-cultural and cross-species manifestations of similar practices that have served for millennia as effective mechanisms for reducing the likelihood of potentially lethal violence. By presenting these manifestations – namely song dueling and mark making – in comparative terms with Hip Hop’s freestyle song and dance battles and tagging territorial contests, this article seeks to highlight the relevance and potential of Hip Hop for preventing violence while also suggesting a common evolutionary backdrop within the context of strategies aimed at minimizing intraspecific aggression.  相似文献

Research has long linked academic engagement to positive social, psychological, and physical developmental outcomes; however, qualitative studies in high-performing schools find that some students who work hard in school may be compromising their mental and physical health in the pursuit of top grades. Such research calls for closer and more contextualized examinations of the concept of engagement. This study examines academic engagement in a sample of 6,294 students (54 % female; 44 % White, 34 % Asian, and 22 % other racial or ethnic background) attending 15 high-achieving schools. Findings show that two-thirds of students at these schools are not regularly “fully engaged” in their academic schoolwork; that is, they do not regularly report high levels of affective, behavioral and cognitive engagement. Although most students report working hard, few enjoy their schoolwork and find it valuable. This lack of full engagement, particularly the absence of affective and cognitive engagement, is associated with more frequent school stress, higher rates of cheating, and greater internalizing, externalizing, and physical symptoms of stress. The study also finds that full engagement is strongly related to positive teacher-student relationships. Implications for practice and future research are discussed.  相似文献

Sipping alcohol during childhood may be a marker of differentiation as regards children’s future risk of underage drinking; yet very little is known about alcohol use when it occurs among elementary school-aged children. The purpose of the present study is to examine alcohol sipping behavior in a sample of third-grade school children to learn whether sipping is associated with attributes that could increase children’s likelihood of further underage drinking. We collected telephone interview data from 1,050 mothers and their third grade children (mean age 9.2 years; 48.2 % male) residing in the Southeastern United States. The majority of mothers were White non-Hispanic (69.02 %) or Black non-Hispanic (21.3 %); most (85 %) lived in households shared with fathers or other adult caretakers. We hypothesized that children who sip alcohol would score lower than abstinent peers on indicators of competence and score higher on indicators of exposure to alcohol-specific socialization by parents and peers. A multivariate model controlling for frequency of parent alcohol use and demographic covariates showed that children who had sipped alcohol were significantly less likely than abstinent peers to affirm indicators of competence and significantly more likely to affirm indicators of exposure to alcohol specific socialization by parents and by same age peers. These preliminary findings suggest that developmental attributes associated with risk of underage drinking begin to differentiate at least as young as middle childhood. Research is needed to test prospectively for continuity between alcohol risk attributes present in middle childhood and future alcohol use.  相似文献
