The present study was designed to explore the relative efficacy of three types of service delivery intervention models for homeless men with alcohol and/or drug problems: integrated comprehensive residential services provided at one site (Group 1); on-site shelter-based intensive case management with referrals to a community network of services (Group 2); and usual care shelter services with case management (Group 3). In addition to assessing the relative efficacy of these approaches in terms of drug and alcohol use, residential stability, economic and employment status, the project also sought to examine what personal factors best predicted successful outcomes for clients. Clients were assessed at baseline and approximately six months following discharge. All three treatment groups improved significantly over time in terms of reduced alcohol and cocaine use, increased employment, and increased stable housing, but no differential improvement was found among groups. Successful outcomes were predicted by lower recent and lifetime substance use, fewer prior treatment episodes, more stable housing at baseline, fewer incarcerations, and less social isolation.

The Residential Security Maps produced under the aegis of the Home Owners' Loan Corporation (HOLC) are often regarded as significant evidence that the federal government was complicit in expanding segregated housing patterns. This paper suggests a different direction for the analysis of the agency's role and the impact of their maps regarding patterns of real estate appraisal and mortgage credit allocations. It is argued that: (1) whereas the broadly asserted relationship between race and residential security areas can be demonstrated, there are important variations that should drive further research in this sphere, including the significance of other demographic, socioeconomic, and housing variables; (2) despite uniform guidelines, the appraisal surveys and assignments of grades by HOLC were not identical across cities; (3) the approaches utilized by HOLC were not identical to those implemented by the Federal Housing Administration (FHA), making it unlikely these agencies had a cooperative relationship; and (4) the relationship between grades and the distribution of mortgages varied by lender type and between Philadelphia and Pittsburgh, suggesting the importance of local context in examining HOLC as a public policy instrument and its subsequent impact on racial segregation.
