The article argues that the increase in crime and urban violence in Argentina, especially in Buenos Aires, can be explained as an outcome of the interaction of four factors: the new social relations established by neoliberalism; the incapacity of the state to resolve the social conflicts which have arisen from these new social relations; the failure to democratise the security forces; and the exclusion of a sector of society from the rights of effective democratic citizenship. The increase in crime and urban violence is, thus, analysed as a problem of governability. 相似文献

Fair Trade has become a dynamic and successful dimension of an emerging counter-tendency to the neo-liberal globalisation regime. This study explores some of the dilemmas facing the Fair Trade movement as it seeks to broaden and deepen its impact among the rural poor of Latin America's coffee sector. We argue that the efforts to broaden Fair Trade's economic impact among poor, small-scale producers are creating challenges for deepening the political impact of a movement that is based on social justice and environmental sustainability. The study is based on two years' research and seven case studies of Mexican and Central American small-scale farmer cooperatives producing coffee for the Fair Trade market. 相似文献

In forensic evidence, gamma-hydroxybutyric acid (GHB) has frequently been encountered in one of its salt forms (gamma-hydroxybutyrate), but has also been encountered in its free acid form (GHB). Owing to the physical properties, encounters of the free acid have been largely restricted to forensic exhibits comprising aqueous solutions, such as acidic beverages that have been "spiked" or formulated with GHB salts or gamma-butyrolactone (GBL). The analysis of GHB free acid presents particular difficulties including the potential for altering the original proportions of GHB free acid, GHB carboxylate, and GBL in the course of analysis, and discrimination between GHB free acid and carboxylate forms. In this work, the formation of GHB free acid in aqueous solutions (water and/or D2O) was studied as a function of solution pH. Proton nuclear magnetic resonance (1HNMR) and Fourier-transform infrared spectrometry (FT-IR) measurements were obtained on freshly prepared mixtures of NaGHB and HCl stock solutions representing a series of points along the GHB titration curve. Both 1HNMR and FT-IR were shown to track the changing proportions of GHB free acid and carboxylate forms as a function of pH, while simultaneously monitoring for the formation of the lactone (GBL). The results were consistent with acid-base conversion behavior for a carboxylic acid. 1HNMR was shown to provide an ideal means for analysis of aqueous-based GHB/GBL forensic exhibits based on simple dilution of the neat liquid exhibit, without altering the original proportions of GHB free acid, carboxylate, and GBL in the samples. 相似文献

Sharp declines in welfare rolls since the passage of welfare reform legislation have led many to label it a social policy success. Using data from prereform and postreform samples of welfare applicants and recipients, as well as ethnographic data on welfare reform implementation, we examine three hypotheses based on concerns raised during the welfare reform debate about the possible effects of new policies on substance abusers and addicts: First, they would be "scared off," or discouraged from applying to aid by welfare's new requirements surrounding work and treatment. Second, they might be "weeded out," or face discrimination in the application process because of concerns about the difficulty of moving them successfully from welfare to work. Third, they might be "bumped down," or shifted to local aid programs rather than moving from welfare to self-sufficiency. Our empirical analysis finds no evidence of scaring off or weeding out, and some evidence of bumping down. Using ethnographic data, we offer some possible explanations for these findings by placing them in the context of policy change and implementation in the years following welfare reform. 相似文献

Three geographic areas of Italy have been sampled and genotyped for 9 Y chromosome STRs: DYS19, DYS385, DYS388, DYS389 I and II, DYS390, DYS391, DYS392, DYS393. Sampling was focused on residents of small areas, well distant from major urban centres. Only individuals whose grandfather would live in the same area were included. A total of 210 unrelated individuals were collected. Distribution of genetic variation across the three samples and comparison with previously published Italian database indicated that so far Y chromosome diversity has been only partially explored in the Italian Peninsula. 相似文献
