The Royal Commission into Aboriginal Deaths in Custody attributed the high rate of Aboriginal deaths in custody to the over-representation of Aboriginal people in prison. Most analyses of this over-representation focus on the issue of systemic bias in policing, the law or the operation of the criminal justice system. The present article contends that, while discriminatory treatment of Aboriginal people by police and the court system is an historical fact, the leading current cause of Aboriginal over-representation in prison is not systemic bias but high rates of Aboriginal involvement in serious crime. We argue that efforts to reduce Aboriginal imprisonment rates through policing or criminal justice system policy have failed and will continue to fail until they succeed in reducing crime in Aboriginal communities. Future efforts to bring down Aboriginal imprisonment rates should focus on this issue.  相似文献

In recent years, scholarshave turned to alternative representationsof utility to capture motivationalheterogeneity across individuals. In theresearch reported here, we examine twomodels of heterogeneous utility –linear-altruism and inequity-aversion – inthe context of two-person, social dilemmagames. Empirical tests are conducteddrawing on data from experiments andsurveys. We find that the model ofinequity-aversion accounts for asubstantial proportion of the preferencetypes and behavior that are not explainedby the standard model of self-interestedpreferences. In contrast, the altruismmodel does not provide a significantincrease in explanatory power over theinequity-aversion model.  相似文献

The detection and identification of traces of inorganic ions and sugars can play a major role in the forensic investigation of an explosives related incident. This survey investigated the background levels of these substances in the general environment. Six sampling locations were selected from around the mainland of the United Kingdom, representing urban and rural sites. Swab and vacuum samples were collected from different locations within each site including motor vehicles, private houses, hotels, the exterior of buildings, road surfaces, and street signs. Sampling was carried out in summer and winter to investigate changes in the levels of the target species due to seasonal factors such as road treatments or weather. The samples were extracted with water and analyzed for a range of inorganic anions, cations, and sugars using ion chromatography. Most of the target anions were found to be common to all locations. Chloride, sulphate, nitrate, and phosphate were found to be the most common and the most abundant. Chlorate was found at a low level in some external samples. Perchlorate and thiocyanate were not detected in any samples. There was a marked increase in the quantity of sodium and chloride detected in samples collected during the winter. Sodium and calcium were detected in most samples. Potassium and magnesium were detected in approximately half of the samples. Ammonium was less common but detected at significant levels in wall samples. Glucose, fructose, and sucrose were detected in the vacuum samples from the interior surfaces of houses, hotels, and cars.  相似文献

North Carolina offers its residents the opportunity to cast early in-person (EIP) ballots prior to Election Day, a practice known locally as “One-Stop” voting. Following a successful legal challenge to the state’s controversial 2013 Voter Information and Verification Act, North Carolina’s 100 counties were given wide discretion over the hours and locations of EIP voting for the 2016 General Election. This discretion yielded a patchwork of election practices across the state, providing us with a set of natural experiments to study the effect of changes in early voting hours on voter turnout. Drawing on individual-level voting records from the North Carolina State Board of Elections, our research design matches voters on race, party, and geography. We find little evidence that changes to early opportunities in North Carolina had uniform effects on voter turnout. Nonetheless, we do identify areas in the presidential battleground state where voters appear to have reacted to local changes in early voting availability, albeit not always in directions consistent with the existing literature. We suspect that effects of changes to early voting rules are conditional on local conditions, and future research on the effects of election law changes on turnout should explore these conditions in detail.
