The proposed Traffic Stops Statistics Study Act of 2001—Title II of Senate Bill 19 of the 107th Congress—was the third consecutive legislative proposal aimed at addressing the perceived problems of racial profiling and police abuse in the detention of minority motorists for allegedly unjustifiable reasons. The measure followed Senate Bill 821 from the 106th Congress and House Bill 118 from the 105th Congress. This study looks at the purpose of these bills, explores the reasons supporters believe that federal policy mandating law enforcement agencies to collect racial data on motorists stopped and detained is needed, and examines a number of public policy questions that a Traffic Stops Statistics Study Act might raise.  相似文献

The Group of Eight Countries (G8) launched the New Alliance for Food Security and Nutrition to improve nutritional outcomes through private sector involvement in agricultural development. The accession of Malawi to the Alliance reveals the assumptions behind the intervention. We show that while the New Alliance may seem to have little to do with nutrition, its emergence as a frame for the privatization of food and agriculture has been decades in the making, and is best understood as an outcome of a project of nutritionism. To highlight the failings of the approach, we present findings from the Soils, Food and Healthy Communities Initiative in northern Malawi, which has demonstrated success in combatting malnutrition through a combination of agroecological farming practices, community mobilization, women's empowerment and changes in intrahousehold gender dynamics. Contrasting a political economic analysis of the New Alliance alongside that of the Soils, Food and Healthy Communities Initiative shows the difference between a concern with the gendered social context of malnutrition, and nutritionism. We conclude with an analysis of the ways that nutrition can play a part in interventions that are inimical, or conducive, to freedom.  相似文献

Thomas Hobbes is often viewed as a seminal figure in the development of the homo economicus philosophical anthropology central to the acquisitive, bourgeois morality of liberal modernity. The present study challenges this interpretation of Hobbes as an antecedent to free market ideology by arguing that his political economy presupposed a complex relation between contract, law, and social networks of credit informed by prudence and robust norms of equity. The normative claims of equity permeate Hobbes's holistic account of political economy and inform his vision of liberal statecraft that gave priority to prudential judgment against economic determinism, especially as Hobbes understood trade, taxation, allocation of resources, and the provision of social welfare. I will conclude by reflecting upon how Hobbes's political economy both reveals the internal diversity within the liberal intellectual tradition and can help us to better understand and critique contemporary liberal states and democratic theory.  相似文献

Our present inability to rapidly, accurately and cost-effectively identify trace botanical evidence remains the major impediment to the routine application of forensic botany. Grasses are amongst the most likely plant species encountered as forensic trace evidence and have the potential to provide links between crime scenes and individuals or other vital crime scene information. We are designing a molecular DNA-based identification system for grasses consisting of several PCR assays that, like a traditional morphological taxonomic key, provide criteria that progressively identify an unknown grass sample to a given taxonomic rank. In a prior study of DNA sequences across 20 phylogenetically representative grass species, we identified a series of potentially informative indels in the grass mitochondrial genome. In this study we designed and tested five PCR assays spanning these indels and assessed the feasibility of these assays to aid identification of unknown grass samples. We confirmed that for our control set of 20 samples, on which the design of the PCR assays was based, the five primer combinations produced the expected results. Using these PCR assays in a 'blind test', we were able to identify 25 unknown grass samples with some restrictions. Species belonging to genera represented in our control set were all correctly identified to genus with one exception. Similarly, genera belonging to tribes in the control set were correctly identified to the tribal level. Finally, for those samples for which neither the tribal or genus specific PCR assays were designed, we could confidently exclude these samples from belonging to certain tribes and genera. The results confirmed the utility of the PCR assays and the feasibility of developing a robust full-scale usable grass identification system for forensic purposes.  相似文献
