We calculate the parton level cross section for the production of two jets that are far apart in rapidity, subject to a limitation on the total transverse momentum Q0 in the interjet region. We specifically address the question of how to combine the approach which sums all leading logarithms in Q/Q0 (where Q is the jet transverse momentum) with the BFKL approach, in which leading logarithms of ...

This paper examines the relationships between the residential choices of individuals and aggregate segregation patterns. Analyses based on computational models show that high levels of segregation occur only when individuals' preferences follow a threshold function. If individuals make finer-grained distinctions among neighborhoods that vary in racial composition, preferences alone do not lead ...

This paper first utilizes annual surveys between the 1981 and 2000 waves of the National Longitudinal Survey of Youth to estimate the effect of being overweight on hourly wages. Previous studies have shown that white women are the only race-gender group for which weight has a statistically significant effect on wages. This paper finds a statistically significant continual increase in the wage p...

Demographic correlates of subjective religiosity are examined using data from five large national probability samples (i.e., Americans Changing Lives, n = 3,617; General Social Survey, n = 26,265; Monitoring the Future, n = 16,843; National Black Election Survey, n = 1,151; and National Survey of Black Americans, n = 2,107). In analyses of data involving both Black and White respondents, race e...

In this article we present new evidence of cross-border shopping in response to sales taxation. While several instructive studies provide estimates of the cross-border shopping effect, we utilize a unique opportunity to evaluate the effect of a large discrete change in sales tax policy. Using county level data on food sales and sales tax rates for West Virginia over the 1988-1991 period we esti...

Recent reports by ethnographic researchers and media sources suggest that many African American students view academic success as a form of "acting white," and that peer pressure reduces their level of effort and performance. This article analyzes the National Education Longitudinal Study of 1988 to answer three questions: (1) do blacks experience greater alienation toward school than non-Hispa...

To highlight how historical scholarship can be used to teach students about a range of topics in psychology, I have chosen three sample articles from the journal History of Psychology that address gender, race/ethnicity, and the intersection of sexuality and disability in historical perspective. I outline how these articles can be incorporated into courses across the curriculum to deepen studen...
