Recent studies suggest a decline in the relative Black effect on violent crime in recent decades and interpret this decline as resulting from greater upward mobility among African Americans during the past several decades. However, other assessments of racial stratification in American society suggest at least as much durability as change in Black social mobility since the 1980s. Our goal is to assess how patterns of racial disparity in violent crime and incarceration have changed from 1980 to 2008. We argue that prior studies showing a shrinking Black share of violent crime might be in error because of reliance on White and Black national crime statistics that are confounded with Hispanic offenders, whose numbers have been increasing rapidly and whose violence rates are higher than that of Whites but lower than that of Blacks. Using 1980–2008 California and New York arrest data to adjust for this “Hispanic effect” in national Uniform Crime Reports (UCR) and National Crime Victimization Survey (NCVS) data, we assess whether the observed national decline in racial disparities in violent crime is an artifact of the growth in Hispanic populations and offenders. Results suggest that little overall change has occurred in the Black share of violent offending in both UCR and NCVS estimates during the last 30 years. In addition, racial imbalances in arrest versus incarceration levels across the index violent crimes are both small and comparably sized across the study period. We conclude by discussing the consistency of these findings with trends in economic and social integration of Blacks in American society during the past 50 years.  相似文献

Gender Wage Work and Development in North East Brazil   总被引:1,自引:0,他引:1  
The last three decades have witnessed a major expansion of export agriculture in Latin America and the emergence of largely feminised labour forces. Research has illustrated how farms purposefully construct gendered divisions of labour and how women often experience worse pay and conditions than men. However, it is also important to consider how and why gender divisions of labour change. This article does so by examining export grape production in North East Brazil. It locates farms' practices of gendering work within a three-pronged context of rising buyer requirements, changes in labour supply and the influence of rural trade unions.  相似文献

This article examines the key arguments and intellectual influences that have come together over recent decades to produce the case for Scottish independence. In particular, the article draws attention to three crucial, but discordant, ideological themes that have become recurrent features of Scottish nationalist discourse: an analysis of the British state indebted to the New Left; a surprising enthusiasm for the politics of the British labour movement; and a belief that we are witnessing the end of the era of absolute state sovereignty.  相似文献
