Abstract

Though criminological literature shows that the manifestation of punitiveness in the criminal justice system is complex, it rarely differentiates between responses to different kinds of crimes. This constitutes a significant gap in knowledge, as it is widely believed that white-collar crimes are treated leniently. In light of the “heating up” of political rhetoric, the expansion of federal criminal law, and the increased maximum punishments on conviction, the article aims to explore whether prosecutorial and judicial responses to white-collar crimes have become more punitive, employing rarely used datasets from the Bureau of Justice Statistics (BJS) between 1996 and 2014. It is demonstrated that these responses are more complex and less consistently punitive than the rhetoric and policies advanced by politicians. It endeavors to capture the complexity of punitiveness in practice by measuring numerous variables and multiple points in the criminal justice process, studying punitiveness from multiple angles, using prosecution and sentencing data.  相似文献

In the statistical interpretation of forensic glass evidence it is standard practice to make the assumption of homogeneity of the refractive index (RI) of the source glass, or of localized homogeneity. However, the work of Locke and Hayes showed that, for toughened windscreen glass, this assumption might not be true. This work is well cited, but there appears to have been little follow-on published research. Furthermore, the toughening process is something known to affect the refractive index, and is a process that float glass does not undergo. Float glass is a major component of casework in New Zealand and for that reason it would be interesting to know whether the findings of Locke and Hayes apply when dealing with float glass. In this paper we describe an experiment similar to that of Locke and Hayes, systematically examining the variation of RI in a pane of float window glass. It was found that, although there were no systematic differences in refractive index, there were observable differences across the pane.  相似文献

Eighteen external quality assessment (proficiency testing) samples were prepared from client specimens collected with the Intercept® oral fluid collection device and by spiking drug-free oral fluid. Samples were circulated in pairs at quarterly intervals to 13 UK and USA based laboratories for analysis by a panel of OraSure micro-plate Intercept® enzyme immunoassay kits and hyphenated mass spectrophotometric techniques. During the survey, there was a single case of non-specificity in a false report for methadone. The major errors were of lack of sensitivity relative to the concentration thresholds specified for the immunoassays. The sensitivity for overall ‘present’/‘not found’ reports calculated as true positives/(true positives + false negatives) were for the amfetamine specific assay 50%, methyl-amfetamines 93%, barbiturates 64%, cannabinoids 73%, cocaine and metabolites 100%, benzodiazepines 69%, methadone 95%, opiates 79% (opiates excluding oxycodone 93%), phencyclidine 93% and human gamma-globulin 97%. A small number of the sensitivity errors were attributable to errors in chromatographic confirmation techniques.  相似文献

The United States today faces a loss of influence as a world power, a reduction in American independence as a policymaker, and a decline in the standard of living on which Americans have come to depend. History teaches that nations weaker and less productive than the United States can rise to become economic powerhouses and rapidly increase their standards of living. History also teaches that nations failing to recognize their fundamental problems will inevitably decline. American politicians must face what is abundantly clear: the United States is losing ground and must act quickly to reverse its course. This White Paper outlines what must be done. Information about the nation's current status must be analyzed and communicated. Incentives to improve the level of competence in government must be provided and maintained. The emphasis of government policy must be changed to reflect broad economic and technological interests as opposed to special interests. Savings must be encouraged and increased. Infrastructure must be improved Tax laws must be modified to help bring these changes about. Economic and technological issues must be elevated to the importance they require. American thinking must reflect the new realities: that the age of leadership through military power is over, that the requirements for success in the world of the 1990s and beyond require a sound and growing economy that is internationally competitive. The US can accomplish these goals only through foundation-shaking, comprehensive, fundamental changealong the lines we propose herein.This paper is the executive summary (with minor editing modifications) of a white paper that is available from Cornell University's Johnson Graduate School of Management.  相似文献

Analyses of the same NORC poll relied on by Hyman and Sheatsley and a 1994 poll for theTimes Mirror Center for The People & The Press show that sizable portions of the U.S. public were know-nothings on both occasions. OLS regressions on both polls show that, although there are slight differences, essentially the same factors affect knowledge of international politics in 1946 and 1994. At bottom, Americans tend to be uninformed about foreign affairs because they are inattentive to events abroad. If it is true, as some students of U.S. foreign policy claim, that public opinion has an important and growing impact on national security policy, widespread public ignorance recalls Lippmann's concern about the democratic malady.  相似文献
