Environmental hazards created by resource extraction impose numerous risks on rural populations, but have been understudied in quantitative analyses of environmental inequality. This study fills that gap by examining whether neighborhoods with socioeconomic disadvantages are disproportionately proximate to coal impoundments in Appalachia. Coal impoundments are large, hazardous dams that hold billions of gallons of wastewater and slurry, a sludge‐like by‐product of processing coal. I ground this study in William Freudenburg's double diversion framework, which highlights “disproportionality”—the unequal trade‐off between economic benefits and environmental costs of certain industries. Disproportionality is evident in Appalachia, where coal mining makes up a small percentage of the region's jobs, but threatens local communities through the creation of environmental hazards. Spatial regression results indicate that neighborhoods closest to impoundments are slightly more likely to have higher rates of poverty and unemployment, even after controlling for rurality, mining‐related variables, and spatial dependence. The findings also suggest that a neighborhood's proximity to past mining activity is a stronger predictor of impoundment proximity than current levels of mining employment. This article lays the groundwork for future research on resource‐based environmental inequality that considers the uneven spatial distribution of hazards created by resource extraction.  相似文献

This study evaluated a community-based intervention program designed to promote positive youth development and to create positive interactions between police and youth in a non-enforcement environment. A pre–post-design was used to compare the results of the program for participating youth and police officers, particularly changes in each group’s attitudes toward the other. The results showed that participation in the program improved police officers’ and youths’ attitudes toward each other. For youth, the rate of change in attitudes was greatest for minority youth and for youth who had prior negative experience with the police. That is, youth who had negative prior experiences with police and began with negative attitudes toward police developed more positive attitudes toward police as a result of participating in the program. Furthermore, having opportunities for positive interactions between police and youth played an important role in decreasing negative perceptions of police for ethnic minority youth. This study suggests that community-based programs that involve police with youth can improve participants’ attitude toward each other, which might impact future interactions.  相似文献

The paper points out that in dynamic games a player may be better-off if other players do not know his choice of strategy. That is, a player may benefit by not revealing (or not pre-determining) the choice of his action in an information set he (thereby) hopes will not be reached. He would be better-off by exercising his ``right to remain silent' if he believes –- as the empirical evidence shows –- that players display aversion to ``Knightian uncertainty'. In this case, a player who behaves strategically, may wish to avoid revealing his strategy. This is true under various interpretations of the notion of ``strategy profiles'.  相似文献
