It is well known that in finance variances and covariances of asset returns move together over time. Recently, much interest has been aroused by an approach involving the use of the realized covariance (RCOV) matrix constructed from high-frequency returns as the ex-post realization of the covariance matrix of low-frequency returns. For the analysis of dynamics of RCOV matrices, we propose the generalized conditional autoregressive Wishart (GCAW) model. Both the noncentrality matrix and scale matrix of the Wishart distribution are driven by the lagged values of RCOV matrices, and represent two different sources of dynamics, respectively. The GCAW is a generalization of the existing models, and accounts for symmetry and positive definiteness of RCOV matrices without imposing any parametric restriction. Some important properties such as conditional moments, unconditional moments, and stationarity are discussed. Empirical examples including sequences of daily RCOV matrices from the New York Stock Exchange illustrate that our model outperforms the existing models in terms of model fitting and forecasting.  相似文献

Online forums and lay literature suggest that partners of individuals with Autism Spectrum Disorder (ASD) experience depression, distress, and trauma in their everyday lives, exacerbated during the time surrounding diagnosis. In this content analysis, 29 participants were provided with an online open‐ended statement asking them to describe in writing their experiences of discovering that their partners had ASD during their relationships. Six themes emerged, including: facing unique challenges within relationships; insisting partners seek diagnosis; initial shock and relief; losing hope for normalcy; making accommodations within relationships; and wishing for professional support. Marriage and family therapists should help couples minimize blaming and promote self‐awareness, appropriate relationship expectations, and mutual understanding. Future research should explore the overall experience of neuro‐mixed relationships for both partners.  相似文献

This study investigates the value of techniques of neutralization in understanding how people involved in marginal to widely deviant behaviors perform identity work. Based on 33 in‐depth interviews with older adult gamblers, we show how techniques of neutralization are used to align personal and social identities. We describe the techniques of neutralizations our participants use along a continuum of gambling involvement, showing how techniques differ in variety and content and are contingent on larger narratives about appropriate behaviors, identities, and selves operating in contemporary society. Our research helps to refine sociologists' understandings of relationships between levels of involvement in deviant behaviors and identity work.  相似文献

Research suggests that third party-arranged home sharing (“TPAHS”) enables elders to remain at home in advanced age by connecting elder home owners with suitable live-in “matches.” TPAHS potentially saves elders, their families, and Medicaid budgets millions of a dollars per year in avoided and postponed nursing home costs. In interviews with elder TPAHS participants of one TPAHS program, we found that similarity in values, ability to utilize the TPAHS organization's guidance, and, when relevant, familiarity with their matches' mental health challenges, correlated with said participants' satisfaction with their matches while a lack of these qualities correlated with match dissatisfaction. With these findings in mind, we suggest strategies TPAHS organizations can use to best serve the elderly TPAHS participants who may benefit from intensified match support but may not seek it.  相似文献

The family‐focused mental health intervention, ‘Let's Talk About Children,’ has positively influenced the lives of families affected by parental mental illness. This paper outlines the use of this brief, strengths‐based intervention for parents with gambling and other co‐occurring issues from the gamblers’ support services sector. Over a six‐month period, a training manual and accompanying resources were adapted for the gamblers’ support services sector and a targeted training session developed. Nine problem gambling counsellors from three Victorian gambling support services trialled the Let's Talk About Children intervention over a four‐month period. Qualitative data were gathered through focus groups, interviews, and practice enquiry groups to determine the impact of the Let's Talk About Children model for gambling support services. The results are presented as ‘practice wisdoms and recommendations’ reporting on the impact of the trial and to provide some guidance to support others in the implementation of a specific family‐focused intervention. This paper reports on the first exploratory trial of Let's Talk About Children for the gambler's support services sector in Australia.  相似文献

Currently, disabilities organizations are increasingly being challenged by the requirement for individualized service, expectations to show personal outcomes, and the need to base their services on evidence-based practices. Social entrepreneurship (SE) is being put forward as an innovative approach for dealing with these challenges. This article presents a systems approach to SE based on a program logic model. This model identifies the input factors (a strong social vision, exploiting opportunities, maximizing resources), throughput strategies (entrepreneurial orientation, critical thinking skills, networking, capacity building), and outcome components (improving people’s lives, community-building, improving society) of SE at the micro, meso, and macro level. Also, the importance of planning for contextual changes as a social entrepreneur is discussed. The article concludes with presenting three inspiring practices regarding SE in the field of disabilities organizations.  相似文献

The conduct of a participatory research investigation into the everyday literacy of adults with intellectual disability within the context of a PhD thesis highlighted issues related to the ethics of participatory research and the need to revisit and reconsider ethical guidelines around working with individuals with intellectual disability. Tensions were identified between participatory research ideology and the reality of research experiences, with additional issues arising due to disability in the first author.  相似文献
