Modeling the dynamism of HIV information diffusion in multiplex networks of homeless youth

Cascade and threshold models are widely used to predict information diffusion in social networks, yet their characterization of networks as static and monoplex limit their ability to accurately predict how information propagates in dynamic, multiplex social environments. Using data from a peer-led HIV prevention intervention for homeless youth, we determine whether manipulating the baseline social network by (1) adding ties observed at later time points, and (2) accounting for alternative relational contexts improves each model’s predictive accuracy. Results show that the addition of new ties improves the performance of both models, while substituting the context of interaction yields only minor improvements.     

Where Risks and Protective Factors Operate Differently: Homeless Sexual Minority Youth and Suicide Attempts

Using a sample of 628 homeless youth and young adults from eight US cities, this study examines whether the relationship between having been in custody of social services and suicide attempts, and the relationship between engaging in survival sex and suicide attempts differ based on sexual orientation. Findings suggest that being in custody of social services is associated with a significant increase in likelihood of suicide attempts for heterosexual youth, it does not, however, significantly change the already increased risk of suicide attempts for sexual minority youth. Engaging in survival sex appears to be associated with increased risks of suicide attempts for both heterosexual and sexual minority youth, but the increase in likelihood is much stronger for heterosexual youth than for sexual minority youth. Implications for practice and future research are discussed.

The system-of-care for homeless youth: perceptions of service providers

Service providers' perceptions of the system of care for homeless youth are described. Face-to-face structured interviews were conducted with staff at homeless youth agencies in Los Angeles County (L.A. County) regarding organizational and staff characteristics, issues affecting youth, types of available services, gaps in services, and barriers to service delivery.Overall, agencies were large, well established, and provided multiple services. Most agencies (62%) were concentrated in Hollywood, a cruise area of L.A. County. Clear distinctions emerged between large and small agencies; large agencies had more resources, more professional staff, were established longer, and were policy advocates. Typical of other US metropolitan areas, services for homeless youth in L.A. County are located in cruise areas, and are not as readily available in other geographic areas. Such geographic barriers to providing a comprehensive and coordinated system of care can affect youth's pathways out of homelessness.     

Using WhatsApp for a homeless count

The study analyses how the use of instant messaging (WhatsApp) alongside other ICT tools is adequate to complement the count of homeless people in an area. In particular, it describes the methodology used in order to organize the first official count of homeless people in Girona (Catalonia, Spain). Given that this is the first count of individuals experiencing homelessness in the city, it is difficult to say that it is an improvement, but it could be suggested that the app might make the future counts more efficient. Both professional and volunteers and homeless people used WhatsApp to send information. A total of 283 homeless people were detected. Results show that the usage of this application optimized the results of the count. 36.1% of the data were obtained online. Homeless people, who were reluctant to contact directly with the professional team, used WhatsApp to communicate with them, adding up to 19.4% of the data obtained. Results show how communication between homeless people and health and mental health services can be potentially improved with this type of application.     

False security or greater social inclusion? Exploring perceptions of CCTV use in public and private spaces accessed by the homeless

It has been well documented that owing to the vulnerability inherent in their situation and status, the homeless experience high rates of harassment and criminal victimization. And yet, the question of whether CCTV surveillance of public and private spaces – so frequently viewed by the middle classes as a positive source of potential security – might also be viewed by the homeless in similar ways. Within the present paper, I address this issue by considering the possibility that CCTV might be seen by some homeless men and women as offering: a) a measure of enhanced security for those living in the streets and in shelters, and; b) to the extent that security is conceived of as a social good, the receipt of which marks one as a citizen of the state, a means by which they can be reconstituted as something more than ‘lesser citizens’. To test these ideas, I rely on data from interviews conducted with homeless service users, service providers for the homeless, and police personnel in three cities. What is revealed is a mixed set of beliefs as to the relative security and meaning of CCTV.     

A follow-up study of homeless women

This article presents an in-depth analysis of the changes observed in 25 homeless women with drug and alcohol abuse problems participating in a case management program. Participation in the program ranged from 6 to 44 months. Thirty-two percent of all participants' situations were considered to have improved, while 20% remained stable. Less improvement was noted in the situations of women followed for 3 years or more (14.3% improved, 28.6% stable). Domains showing the most improvement were housing, financial situation, and substance abuse. Deterioration was primarily attributable to physical and mental health problems. These findings could indicate that although a case management program can initially contribute to improving the living conditions of its clients, acquisitions are difficult to maintain over an extended period. Health and substance abuse play a crucial role in the deterioration process.     

Homeless Careers: A Framework for Intervention

Abstract

The present paper identifies three ‘homeless careers’ abstracted from the diversity and complexity of individual cases and pathways. These are the ‘youth career’, the ‘housing crisis career’ and the ‘family breakdown career’. The paper discusses the usefulness of the career typology for framing interventions. A core argument is that early intervention involves different forms of practice in each pathway. For young people, early intervention has to occur when they are at the ‘in-and-out’ stage, before they have made a permanent break from family. For adults experiencing housing crisis, early intervention is about providing assistance to people before they lose their accommodation. The family breakdown career commonly involves domestic violence, so although early intervention may involve family reconciliation, in many cases it involves supporting victims of domestic violence to move to alternative, secure accommodation.     

Houston Homeless Street Outreach

Abstract

Several cities in the nation have developed innovative programs to assist the homeless who are “living on their streets.” This paper describes one such program developed in Houston, Texas. The Homeless Street Outreach was a collaborative project of several service agencies in the greater Houston area. The outcome of this outreach project indicates that a coordinated effort can bring about delivery of more comprehensive services to the homeless population. The principles that emerge from the outreach include involvement of the homeless in planning and development, service agencies taking “ownership” of the project, and agency flexibility in delivering services to the homeless.     

A Community-Based Multiple Family Group Intervention for Sheltered Families

Abstract

This study evaluates the effectiveness of a multiple family group intervention developed to improve familial functioning and decrease the frequency of children's behavior problems while families are living in shelters and as they prepare to transition back into more permanent living conditions. The skill-based curriculum focuses on diminishing stress, while helping strengthen families' beliefs, cohesion and structure. Nineteen adults and thirty-five children from five shelters across a mid-south metropolitan area participated in the study. The results showed significant reductions in parents' perceived stress and improvements in families' level of cohesion and their children's maladaptive behaviors. Moreover, effect sizes showed that these changes were clinically significant as well.
