Does mobility matter? The neighborhood conditions of housing voucher holders by race and ethnicity

Abstract

Mobility is one mechanism used to address the federal goals of deconcen‐trating poverty and minorities. The Housing Choice Voucher Program relies on participants to make residential location decisions consistent with these goals. Our research investigates the level and impact of mobility on the neighborhood quality of voucher holders, their neighborhood conditions by race and ethnicity, and perceived obstacles to mobility within the jurisdiction of a Southern California housing authority.

About one‐third of the sample moved during the study, and moving resulted in improved neighborhoods for only one subset of movers. Minorities live in more impoverished, overcrowded neighborhoods than nonminorities, even when controlling for mobility status, contract rent, and other factors. Further, most voucher holders see the lack of rental units as a major obstacle to mobility. These findings suggest that current policy is not uniformly achieving deconcentration and that real and perceived barriers to mobility exist, especially for minorities.

Myths and Realities

Abstract

Frances Fitzgerald has seen a lot and read a lot, and Fire in the Lake has the double merit of being at the same time a vivid report and a well-documented historical study. It is certainly one of the most interesting books ever written on Viet Nam.     

Revisiting the relationship between age,employment, and recidivism

Employment theoretically serves as a source of informal social control that can promote desistance from crime (Sampson & Laub, 1993). Findings from studies assessing the effects of employment, however, have been mixed. In a seminal study, Uggen (2000) reanalyzed data from the National Supported Work (NSW) Demonstration Project and found that employment significantly reduced the rate of recidivism among individuals aged 27 and older but had no impact on younger individuals. We reproduce and replicate Uggen's (2000) findings with data from four distinct employment programs: The National Supported Work Program (1975–1979), the Transitional Aid Research Project (1976–1977), the Employment Services for Ex-Offenders (1981–1984), and the Enhanced Services for the Hard-to-Employ Center for Employment Opportunities (2004–2008). We closely reproduced Uggen's original findings in the NSW but found evidence that the statistically significant interaction between age and employment in the NSW was only present at the year 3 follow-up and the observed effect is highly sensitive to minor threats to internal validity. Furthermore, a significant age–employment interaction was not observed in the three other data sources. These findings should encourage scholars to continue to investigate the age-graded nature of employment and crime, especially through a sociohistorical lens.

Who is Likely to Help and Hurt? Profiles of African American Adolescents with Prosocial and Aggressive Behavior

Prosocial behavior and aggression among children and adolescents are important indicators of social and interpersonal competence. The goal of this study was to investigate whether there are different prototypes among African American adolescents that can help explain prosocial and aggressive (relational and overt) behaviors. Also of interest was whether these profiles differed for boys and girls. The selection of independent variables (e.g., empathy, anger management, normative beliefs about aggression, and ethnic identity) was guided by an information processing model of aggression and prosocial behaviors. The sample consisted of 789 (57% female) African American adolescents between the ages of 11 and 14. Cluster analysis produced three profiles that were similar for boys and girls. These were labeled “well-adjusted,” “poorly adjusted,” and “low identity.” A fourth profile was labeled “low empathy” for girls and “poor anger management” for boys. These four clusters significantly differentiated who engaged in prosocial behavior and relational and overt aggression. Findings suggest that prevention programs may consider targeting well-adjusted youth to serve as peer modes. Additionally, programs that promote empathy, anger management, ethnic identity, and normative beliefs against aggression may be useful for reducing aggression and increasing prosocial behavior among poorly adjusted youth.     

Constructing universal multiplex PCR systems for comparative genotyping

Analysis of length polymorphisms at STR loci in the human genome has become a standard approach for comparative genotyping in many areas including disease research and diagnostics, parentage assessment, investigations of human diversity, and forensic science. The simultaneous analysis of multiple STR loci through multiplex PCR and multicolor fluorescence detection offers sample conservation, high throughput, and automated genetic analysis. Careful design and optimization of tetranucleotide STR multiplexes has led to reliable, standardized systems that powerfully differentiate and distinguish individual human DNA profiles. The development of these multiplex systems involved a rigorous experimental strategy that included careful selection of PCR primer sequences (for yield, specificity, and multiplex compatability), along with optimization of PCR component concentrations, thermal cycling parameters, and fluorescence detection conditions. This developmental approach rendered well-characterized DNA typing systems that are high performing (sensitive, specific, and balanced), optimized to universal parameters (same reaction conditions), resilient to fluctuations in reaction conditions, and simple to implement and use routinely.
