Jared M. Ragusett 《The Review of Black Political Economy》2016,43(3-4):253-272
This paper investigates the relationship between alternative metropolitan land use patterns, including those characterized as “sprawl,” and Black residential segregation. Previous studies have explored this question using limited attributes and empirical measures of both land use and segregation. This econometric study advances the understanding of that relationship in several ways. First, the paper defines land use as a countervailing, multi-dimensional, phenomenon. Metropolitan areas do not generally exhibit high-sprawl (or low-sprawl) characteristics across multiple measures; rather, they typically exhibit some combination, or “configuration,” of low-sprawl and high-sprawl attributes. Second, the paper examines the relationship between such configurations and several of the segregation dimensions suggested by Massey and Denton (1988). Third, the paper analyzes results using the 2010 decennial Census. This study explores the contribution and transmission of countervailing spatial land use patterns to changes in Black segregation levels, and the implications of such changes for land use policies and regulations. These complex effects bring new precision and insights to the analysis of racial inequality in an age of rapid demographic change. 相似文献

Atlanta has the reputation of being a city of opportunity for blacks. However, in Atlanta, as well as in other cities across
the nation, the nexus of racism and economic discrimination has resulted in disparities between the housing status of blacks
and whites. This article examines racial disparities in the Atlanta housing market. It begins by tracing recent trends in
the Atlanta-area economy and by providing background information on the local housing market. It then discusses the roles
of the federal Home Mortgage Disclosure Act of 1975 and Community Reinvestment Act of 1977 in the efforts of local groups
to reduce racial disparities in the housing market. The final section discusses recent local developments that might lead
to improvements in the housing status of black Atlantans. 相似文献

This article assesses recent events leading to the establishment in 1997 of a regional organisation for the Indian Ocean Rim, subtitled an Association for Regional Cooperation (IOR‐ARC). This is a case of ‘open’ regionalism of the functionalist kind. New members may be admitted in 1999 and, as trade integration has not been ruled out, the openness of the design may lead to the changeover from regional cooperation to regional integration after 2004. By 2003 the members of the Association for South‐East Asian Nations (Asean) of the IOR‐ARC will have free‐trade arrangements in that region and by 2004 the SADC members of the IOR‐ARC will be similarly structured, making a free‐trade scenario within the IOR almost irresistible. This will create new problems, making it very difficult for the less competitive nations to endorse their continued membership of this bloc unless project cooperation now under way makes complementarity more meaningful, equipping states and market sectors to cope better with the more competitive nature of free trade that always applies in market integration. This will pose great challenges for South Africa. 相似文献
