Abstract

fetched live from OpenAlex

An aging population and increase in the number of older adults experiencing homelessness in North America requires a more effective response to prevent and end older adult homelessness. While there are few research evidence-based policy solutions to preventing older adult homelessness, there are several promising practices that with further analysis could point to quality policy reform. Using the five-level typology by Fitzpatrick et al. (2021. Advancing a five-level typology of homelessness prevention. International Journal on Homelessness, 1(1), 79-97. doi:10.5206/ijoh.2021.1.13341), this discussion paper outlines policy-oriented recommendations at varying levels of prevention: (a) universal, (b) upstream, (c) crisis, (d) emergency, and (e) repeat. Key policy implications include intersectoral collaboration and policy design that seeks to successfully reach functionally zero homelessness by activating policy strategies at each of the five-levels of prevention. Health and housing practitioners play an essential role in policy planning, design, implementation, and evaluation and can participate in and advocate for opportunities to improve services and address older adult homelessness connected to their practice environments. Promoting research that enhances systematic evaluation of the outcomes of older adults through various housing models is critical to driving policy reform-a necessary action to promote a safe, healthy, and opportunistic future for older adults.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
