Research has shown that youth aging out of the foster care system experience an increased risk for several adverse adult outcomes (e.g., homelessness, unemployment, low educational attainment). Yet, fewer studies have examined the impact of homelessness on adult outcomes. The current study uses National Youth in Transition Database (NYTD) to examine the associations between homelessness and two outcomes, post-secondary education and employment status, for transition-aged foster youth (N = 4,235). This study found that youth who experienced homelessness between 19 and 21 years were less likely to have post-secondary education or full-time employment, controlling for individual and foster care characteristics.  相似文献

Consistent with the view that adolescent relationships are established in the context of important characteristics of their social networks, we examined the effects of adolescents’ experiences of parenting (psychological control and positive monitoring) and of peer aggression and victimization, on their self reports of dating victimization and aggression. We also examined the effects of individual differences in emotional and behavioral problems. We used questionnaire data from a population-based sample of youth 12–18 years old who were in dating relationships (n = 149). Parental monitoring emerged as a protective factor in reducing both dating victimization and relational aggression. Our findings also point to a significant transfer of aggression in peer relationships to relational aggression in dating relationships.

As membership levels decline, parties are developing new forms of linkage with supporters, many of which rely on Internet technologies. To date, the discussion of these new modes of affiliation has been largely theoretical in nature, with little, if any, systematic empirical analysis undertaken on their appeal and impact on formal membership. This article seeks to fill this gap by examining the presence of three new types of digital affiliation—audience, friends, and digital activists—among the French electorate using original survey data from the 2012 Presidential election. Our findings are important in showing that while the new methods of affiliation are increasing parties’ reach into society, they are not necessarily widening parties’ socioeconomic support base. Furthermore, digital activism is mostly a supplementary channel for members’ input although there are a smaller group of people engaging in these activities that avoid formal membership ties. Such results suggest that digital methods of affiliation might offer an important new resource to parties during campaigns.  相似文献

This article explores the reasons why the conveyance of foreclosed homes with occupants makes sense, and why nonprofits should be given preferential treatment as purchasers, as well as the relevant policies and practices of the U.S. Department of Housing and Urban Development and the Federal Housing Administration (HUD/FHA) and the Federal Housing Finance Agency and the Government-Sponsored Enterprises (FHFA/GSEs). It also presents recommendations for revising current policies, and suggestions for further research. These issues also raise underlying questions about how the federal agencies view their public purpose roles and the implications for possible increased long-term public costs to shelter low-income households displaced because of foreclosure of their homes. Although HUD/FHA’s guidelines allow for conveyance of foreclosed homes with occupants, the evidence—interviews with key stakeholders in Boston and data obtained from HUD through a Freedom of Information Act (FOIA) request—reveal that the guidelines are largely irrelevant in practice. Although there has been a change in an FHFA policy that could soften the GSEs’ practice of no occupants at conveyance, it is not yet clear whether this will result in former owners and tenants being allowed to remain in their homes following foreclosure. Concerning preferential sales to nonprofits, whereas positive new policies have been issued by both the FHFA and HUD, the extent of implementation is not known. Finally, it appears that HUD/FHA and the FHFA/GSEs view foreclosed homes more as financial assets, whose value they seek to maximize, rather than as dwellings for financially strained households that, if evicted, may need additional housing subsidies and as part of a strategy to preemptively stabilize neighborhoods.  相似文献

Abstract

Bringing together the work of Barad and Deleuze, this article develops the concept of the living present as a frame for an emerging feminist temporality. Within feminist and queer theories, there has been much discussion of the value of non-chronological time in opening up a transformative and unknown future. The author expands on this arena by discussing not only the future, but also the echoes, resonances and traces of the past—a past whose material effects continue to act as living, changing forces on the present and the future. Described as the present of retention and expectation, the living present is never a static ‘now’, but always a stretching between past and future as it contracts all past experiences and expects those yet to come. As it builds on the work of Grosz, Colebrook and others, the living present encourages non-linear, open-ended readings of past events, and therefore represents a new lens through which to approach documented and assumed histories. By opening up collaborative lines of flight between new materialism, Deleuze and feminism, the thick time of the living present reveals a past of forceful, intra-active materialities. It is a realm of possibility to which one is accountable, but not bound.  相似文献

What explains when and to what extent central governments implement decentralization? By centering on the strategic incentives that follow from the particular configuration of competitiveness and party system coherence, we propose a theory that can begin to explain the divergent outcomes in the many forms of decentralization initiated across Africa. This explanation for the extent to which robust decentralization is implemented over time suggests two counter-intuitive findings. First, authoritarian regimes may decentralize further than democratic ones, given the incentives to the hegemonic party where such reforms are initiated. Second, highly fragmented and deeply localized polities may decentralize most minimally, even where there is a broad consensus about the desirability of such reforms. We provide a first test of the theory through a comparative analysis of over a dozen countries, focusing on process tracing for Ethiopia, Botswana, Ghana, and Benin.  相似文献

How does the Islamic State in Iraq and Syria (ISIS) leverage Islamic Law to support their strategic objectives? Islam, as most religions, is a defining catalyst of group identity. ISIS has capitalized on this, using it as a vehicle to legitimize its interpretation of Islamic Law. This study builds on Social Movement Theory to develop and test a conceptual framework of ISIS messaging strategies. This framework highlights the progression of the organization's message from mainstream Islamic Law to radical unified reinterpretation. ISIS leaders' speeches are used to test the model. Ultimately, study findings inform countermessaging strategies and identify mobilization mechanisms.  相似文献

Body image and eating concerns are prevalent among early adolescent girls, and associated with biological, psychological and sociocultural risk factors. To date, explorations of biopsychosocial models of body image concerns and disordered eating in early adolescent girls are lacking. A sample of 488 early adolescent girls, mean age = 12.35 years (SD = 0.53), completed a questionnaire assessing depressive symptoms, self-esteem, body mass index (BMI), sociocultural appearance pressures, thin-ideal internalization, appearance comparison, body image concerns and disordered eating. Structural equation modelling was conducted to test a hypothetical model in which internalization and comparison were mediators of the effect of both negative affect and sociocultural influences on body image concerns and disordered eating. In addition, the model proposed that BMI would impact body image concerns. Although the initial model was a poor fit to the data, the fit was improved after the addition of a direct pathway between negative affect and bulimic symptoms. The final model explained a large to moderate proportion of the variance in body image and eating concerns. This study supports the role of negative affect in biopsychosocial models of the development of body image concerns and disordered eating in early adolescent girls. Interventions including strategies to address negative affect as well as sociocultural appearance pressures may help decrease the risk for body image concerns and disordered eating among this age group.  相似文献
