This study examined whether children who become homeless differ from other low-income children in their mental health service use before and after their first homeless episode, and to what extent homelessness is associated with an increased likelihood of mental health service use. Differences between children with and without new onset of sheltered homelessness in the use of mental health services emerged following homelessness and widened over time. Sheltered homelessness and foster care placement history were associated with increased odds of receiving inpatient and ambulatory mental health services. Findings underscore the importance of collaborations between homeless assistance, foster care, and mental healthcare in efforts to mitigate family homelessness and collateral needs among homeless children. 相似文献

Parental divorce is a life transition that affects a substantial number of children each year. The purpose of this study was to investigate the relationship between social support and confidence levels (defined as career expectations and confidence in romantic relationships) for those impacted by parental divorce. Three hundred and twelve young adults participated in the study. The results indicate that the quality of social support had a significantly positive relationship with career expectations and romantic relationship confidence. The findings suggest quality relationships regarding social support are more significant than quantity or amount of social support given by parents, family members, or friends. 相似文献

Homelessness is related to poorer mental health, yet, there is limited understanding of the predictors of mental health of men and women experiencing homelessness. To support service providers in identifying individuals who might be at particular risk of poor mental health, this study investigated the predictors of mental health in 501 single men and women experiencing homelessness in Vancouver, Toronto, and Ottawa, Canada. Data were obtained via in-person, structured interviews. In order to identify whether predictors differ by gender, multiple linear regressions were conducted separately for men and women. Mental health status was measured by the Mental Component Summary score of the 12-item Short-Form Health Survey. Better mental health for men and women was associated with the presence of fewer chronic health conditions and a higher level of social support. An older age, not having experienced a recent physical attack, and absence of a mental health diagnosis were related to better mental health for women. The absence of unmet mental health needs within the past 12 months was associated with better mental health for men. The study highlights differences in factors associated with mental health for men and women. Service providers should be aware of the association of these factors with mental health to guide assessment and service planning. 相似文献

Can previously unacquainted, grieving individuals who use social media to organize and participate in decentralized mobilizations build strong, lasting social ties? If so, how? What is it about particular social media technologies and platforms that might explain the strength and longevity of their social ties? Drawing on a case study of New Orleans bloggers who took part in a variety of contentious and non-contentious mobilizations after hurricane Katrina, we find that people who mobilize through social media like blogs can form strong and lasting social ties. We argue that this is partly because of the types of communication and interaction that blogs afford. We identify two types of affordances, mechanical and cultural, as distinct qualities of social media like blogs, and illustrate how they enable the building of strong, digitally mediated social ties among grieving people. 相似文献

This paper questions whether asylum seeker integration is promoted through inter-organisational relationships between non-profit and voluntary organisations (NPVOs) and government agencies. It focuses particularly on the role of NPVOs in service delivery (co-management) and in the delivery and planning of public services (co-governance). It presents a research study on the public services provided to asylum seekers in Glasgow and asks the following questions: What role do NPVOs play in the planning and delivery of public services? When planning and delivering public services, to what extent do NPVOs work across organisational boundaries and what kind of relationships exist? And in practice, what makes inter-organisational relationships work? This paper offers new empirical evidence and also contributes to the theoretical debate around the integration of asylum seekers. 相似文献

We postulate a dynamic spatio-temporal model with constant covariate effect but with varying spatial effect over time and varying temporal effect across locations. To mitigate the effect of temporary structural change, the model can be estimated using the backfitting algorithm embedded with forward search algorithm and bootstrap. A simulation study is designed to evaluate structural optimality of the model with the estimation procedure. The fitted model exhibit superior predictive ability relative to the linear model. The proposed algorithm also consistently produced lower relative bias and standard errors for the spatial parameter estimates. While additional neighbourhoods do not necessarily improve predictive ability of the model, it trims down relative bias on the parameter estimates, specially for spatial parameter. Location of the temporary structural change along with the degree of structural change contributes to lower relative bias of parameter estimates and in better predictive ability of the model. The estimation procedure is able to produce parameter estimates that are robust to the occurrence of temporary structural change. 相似文献

ABSTRACTIn this paper, we examine the issue of detecting explosive behavior in economic and financial time series when an explosive episode is both ongoing at the end of the sample and of finite length. We propose a testing strategy based on a subsampling method in which a suitable test statistic is calculated on a finite number of end-of-sample observations, with a critical value obtained using subsample test statistics calculated on the remaining observations. This approach also has the practical advantage that, by virtue of how the critical values are obtained, it can deliver tests which are robust to, among other things, conditional heteroskedasticity and serial correlation in the driving shocks. We also explore modifications of the raw statistics to account for unconditional heteroskedasticity using studentization and a White-type correction. We evaluate the finite sample size and power properties of our proposed procedures and find that they offer promising levels of power, suggesting the possibility for earlier detection of end-of-sample bubble episodes compared to existing procedures. 相似文献
