Correlates of Housing Sustainability Among Youth Placed Into Permanent Supportive Housing and Rapid Re-Housing: A Survival Analysis.

PURPOSE: Youth experiencing homelessness (YEH) are vulnerable to multiple adverse health outcomes. Connecting YEH with housing is critical to addressing youth homelessness and to preventing long-term negative health consequences among this vulnerable population. Using administrative data, this study aims to explore correlates of YEH's sustainability in two major housing programs: permanent supportive housing (PSH) and rapid re-housing (RRH) programs. METHODS: This study used Homelessness Management Information System administrative data collected from 16 communities across the U.S. between January 1, 2015 and May 1, 2017 (n = 10,902). We conducted Cox proportional hazards survival analyses to explore correlates (e.g., demographics, homeless experiences, and overall vulnerability) of YEH's PSH (n = 577) and RRH (n = 2,883) sustainability separately. RESULTS: For YEH receiving PSH, only individuals' level of vulnerability is associated with greater hazard of exiting PSH. As for RRH sustainability, YEH who were 17 years old or younger, black or Latinx (as compared to white), of higher level of vulnerability, or previously spent most nights couch surfing or in transitional living programs (as compared to on the street) are associated with higher hazard of exiting RRH. CONCLUSIONS: Both PSH and RRH programs should incorporate comprehensive services targeting youth experiencing high vulnerability to prevent them from re-entering homelessness. Future RRH programming should also address housing sustainability disparities faced by racial and ethnic minority YEH, especially when they are disproportionately influenced by homelessness. Finally, RRH programs should incorporate services to foster independent living among younger YEH to sustain their housing status once temporary housing subsidies expire.

Understanding Wait Times in Rapid Re-Housing Among Homeless Youth: A Competing Risk Survival Analysis.

Approximately 3.5 million youth experience homelessness in the United States. Assisting youth to exit homelessness as quickly as possible through various housing venues aims to prevent adverse health impacts that prolonged homeless experiences may have on youth. Rapid re-housing (RRH) is a recent, short-term, less costly housing option than permanent supportive housing that provides temporary housing supports and services to counter homelessness. Although previous literature indicates that youth are likely to achieve stable homelessness exits via RRH, the duration of wait times for youth and potential disparities in RRH waiting periods remain unclear. We used administrative data from 16 communities across the United States (N = 10,920) to gain a greater understanding about RRH wait times among homeless youth. In addition, we adopted a competing risk survival analysis to investigate potential disparities (i.e., race and ethnicity, gender, rurality, sexual orientation, and previous homelessness condition) in RRH wait times while taking into consideration the presence of other homelessness exit options (e.g., permanent supportive housing). Study results indicate that RRH is a common homelessness exit for homeless youth and is prioritized for youth assessed as mid-vulnerability, per commonly accepted assessment measures of youth vulnerability. However, youth who received RRH waited, on average, 131 days following their housing eligibility assessment. Furthermore, being a minor (i.e., 17 years old or younger), experiencing homelessness in rural communities, and lower engagement in homeless services (e.g., emergency shelters and transitional living programs) were all associated with lower probability of exiting into RRH over time, taking into account the possibility of other competing homelessness exits. Expansion of the short-term housing supports offered through RRH may be a promising strategy to counter homelessness among youth in a timely manner. However, such an expansion should also address the potential disparities underlying youths' wait time to receive RRH in order to reduce prolonged homelessness experiences within this vulnerable population.

Online detection of the modality of complex-valued real world signals.

A novel method for the online detection of the modality of complex-valued nonlinear and nonstationary signals is introduced. This is achieved using a convex combination of complex nonlinear adaptive filters with different transient characteristics. To facilitate the online mode of operation, the convex mixing parameter lambda within the proposed architecture is made gradient adaptive. Our focus is on the most important aspect of complex nonlinear modeling, that is, the identification of the split-complex and fully-complex nature of the signal in hand. The algorithms derived are robust and capable of tracking the changes in the modality of both benchmark and real world radar and wind complex vector fields.
