Job sprawl,spatial mismatch,and black employment disadvantage

This paper examines the relationship between job sprawl and the spatial mismatch between blacks and jobs. Using data from a variety of sources, including the 1990 and 2000 U.S. Census and U.S. Department of Commerce's ZIP Code Business Patterns, I control extensively for metropolitan area characteristics and other factors. In addition, I use metropolitan area physical geography characteristics as instruments for job sprawl to address the problem of simultaneity bias. I find a significant and positive effect of job sprawl on mismatch conditions faced by blacks that remains evident in the twostage least squares models but not in first difference change regressions. The crosssectional effect is particularly important in the Midwest and West, and in metropolitan areas where blacks' share of the population is large and where blacks' population growth rate is relatively low. Among others, the results also reveal that the measures of mismatch and job sprawl used in this analysis are highly correlated with blacks' employment outcomes in the expected direction. © 2006 by the Association for Public Policy Analysis and Management     

Axonal injury in young pediatric head trauma: a comparison study of β-amyloid precursor protein (β-APP) immunohistochemical staining in traumatic and nontraumatic deaths

We tested the independent utility of β-amyloid precursor protein (β-APP) immunohistochemical staining as evidence of brain trauma in the deaths of young children. Blinded reviewers retrospectively reviewed immunostained brain tissues from homicidal deaths, age-matched control cases without evidence of trauma, as well as cases of sudden infant death syndrome (SIDS). The reviewers correctly identified five of the seven cases with documented inflicted head trauma. However, one of seven age-matched control cases and one of 10 SIDS/sudden unexplained death in infancy (SUDI) cases demonstrated staining patterns similar to those seen in cases of inflicted trauma. We discuss these cases and the circumstances surrounding them with the intent to explain the difficulties associated with immunohistological interpretation of axonal injury. Although the utility of β-APP is quite powerful if not confounded by global hypoxic-ischemic injury, ultimately, β-APP studies should be only one piece of information in the determination of cause and manner of death.     

Redlining or risk? A spatial analysis of auto insurance rates in Los Angeles

Auto insurance rates can vary dramatically, with much higher premiums in poor and minority areas than elsewhere, even after accounting for individual characteristics, driving history, and coverage. This paper uses a unique data set to examine the relative influence of place‐based socioeconomic characteristics (or redlining) and place‐based risk factors on the place‐based component of automobile insurance premiums. We use a novel approach of combining tract‐level census data and car insurance rate quotes from multiple companies for sub‐areas within the city of Los Angeles. The quotes are for a hypothetical individual with identical demographic and auto characteristics, driving records, and insurance coverage. This method allows the individual demographic and driving record to be fixed. Multivariate models are then used to estimate the independent contributions of these risk and redlining factors to the place‐based component of the car insurance premium. We find that both risk and redlining factors are associated with variations in insurance costs in the place‐based component, with black and poor neighborhoods being adversely affected, although risk factors are stronger predictors. However, even after risk factors are taken into account in the model specification, SES factors remain statistically significant. Moreover, simulations show that redlining factors explain more of the gap in auto insurance premiums between black (and Latino) and white neighborhoods and between poor and nonpoor neighborhoods. The findings do not appear sensitive to the individual characteristics of the hypothetical driver. © 2007 by the Association for Public Policy Analysis and Management     

Rednecks,Norteños,and the Next American Melting Pot?

When Americans are frightened by ethnic or racial polarization, one response is the melting pot, a metaphor for intermarriage. Marriage across ethnic or racial lines turns distrustful groups into contributors to each other’s demographic future. Melting pots have been multiple in American history. While they often have been constrained by racial prejudice, racial intermarriage is now on a slow but steady upswing. Two groups that bear watching are Rednecks, who descend from British migration to what is now the United States, and Norteños, a term I use to refer to Mexican migration streams that, like Rednecks, have become a cultural model for a wider spectrum of Americans. Both Rednecks and Norteños originated as frontier populations in which the struggle for survival selected for self-reliance, distrust of government and the family-first principle. While both are beset by pejorative imagery of machismo, racism and criminality, their strong sense of kinship is a sign that they have more in common than might appear. Just as it is a mistake to reduce all relationships between white and black Americans to racism, it is also a mistake to assume that Norteños and Rednecks are necessarily hostile to each other. Despite the limitations of the melting pot metaphor, it does provide a plausible alternative to racialism.     

Determinants of the Psychosocial Adjustment of Southern Sudanese Men

Our study examines the psychosocial adjustment of 164 SouthernSudanese men who are resettling in a western Canadian city.Special emphasis is placed on the role of financial and emotionalstrain associated with their sending money to relatives in Africa.Key findings point to the importance of religiosity in predictingtheir psychological adjustment, and social support and reducedfinancial role strain in predicting their social adjustment.Findings serve to guide the provision of culturally appropriateservices and policies for African immigrants and refugee claimantsin Canada.
