Despite a large literature on public views about crime, the racialization of crime, and the contact hypothesis, surprisingly little is known about how interracial friendships may influence Whites’ fear of crime. At the same time, and perhaps because no counterpart stereotype to that of “Blacks as criminals” exists, there has been little exploration of how such contact may influence Blacks’ fear of crime. To address these research gaps, this study built on prior theory and research and used data from an ABC News and Washington Post poll to test competing hypotheses about the effect of interracial contact on Whites’ and Blacks’ fear of crime, respectively. The analyses revealed that close interracial friendships are associated with increased fear of crime among Whites, decreased fear of crime among lower-income Blacks, and increased fear among higher-income Blacks. The implications for theory and research are discussed. 相似文献

The harm principle, understood as the normative requirement that conduct should be criminalized only if it is harmful, has
difficulty in dealing with those core cases of criminal wrongdoing that can occur without causing any direct harm. Advocates
of the harm principle typically find it implausible to hold that these core cases should not be crimes and so usually seek
out some indirect harm that can justify criminalizing the seemingly harmless conduct. But this strategy justifies criminalization
of a wide range of conduct on the basis of the fear, worry, and anxiety it generates among those who are not the direct victims
of the conduct, and thereby undermines the limiting role of the harm principle by permitting the very move it was meant to
prevent: the criminalization of harmless conduct on the ground of others’ feelings about it. The best way to avoid this dilemma
is to recognize that people have rights, operating independently of the harm principle, to be treated in certain ways just
because they are persons. The existence of such rights provides a ground for both criminalizing conduct and limiting the scope
of criminalization because these rights point both to conduct that people must be permitted to engage in (regardless of its
harmful effects) and conduct that might well be criminalized (though it is not harmful). A complete account of criminal law
will therefore require the harm principle to work together with an independent account of rights. 相似文献

This paper compares police trainings and materials on pre-attack indicators in police-citizen interactions with similar behavioral indicators of stereotype threat, which is not necessarily a sign of danger. Stereotype threat is a social identity threat in which individuals feel that they may be judged or treated negatively based on a social group stereotype (Steele 1997). This psychological threat can increase the target’s anxiety, physiological arousal, and decrease cognitive capacity. We hypothesize that symptoms of stereotype threat might be similar to pre-attack indicators being taught to police in the USA, which can lead police to potentially misinterpret a citizen’s actions. Using a deductive content analysis, three coders analyzed a sample of pre-attack indicator police trainings for three indicators of stereotype threat: anxiety, arousal, and reduced cognitive capacity. Results found significant overlap between danger indicators taught in trainings and stereotype threat indicators. All 15 identified trainings contained at least one of the three indicators of stereotype threat, and 13 contained at least two indicators. None of the trainings discussed stereotype threat. We argue that stereotype threat should be taught in addition to relevant indicators of danger in trainings, lest officers misinterpret citizens’ stereotype threat-related behaviors solely as manifestations of imminent danger. 相似文献

An investigation into the effects of physical and chemical enhancement on subsequent presumptive and confirmatory tests for human blood is presented. Human blood was deposited onto porous (white 80 gsm paper and brown envelope) and non-porous (tile and linoleum) substrates in a depletion series (30 depletions on non-porous and 20 on porous) and subjected to three ageing periods; 1, 7 and 28?days. A number of enhancement techniques were tested [fluorescence, black magnetic powder (BMP), iron-oxide black powder suspension (PS), cyanoacrylate (CA) fuming, acid violet 17 (AV17), acid yellow 7 (AY7), ninhydrin, DFO and Bluestar Forensic Magnum (BFM) luminol] to evaluate their potential effects on subsequent presumptive and confirmatory tests. AV17 and Bluestar provided the best enhancement and fully enhanced all depletions in the series. The sensitivity of the Kastle-Meyer (KM) (presumptive), Takayama and RSID-Blood tests (confirmatory) was initially investigated to determine the range of detectable depletions. The KM test detected all depletions, whereas the Takayama test detected up to depletion 6 and RSID-Blood detected up to depletion 20 (paper), 10 (envelope), 15 (tile) and 9 (lino). The abilities of these tests to detect blood after enhancement were then observed.A number of techniques resulted in little to no effect on any of the blood tests, whereas adverse effects were observed for others. Ninhydrin and CA fuming caused weak but instantaneous positive KM results whereas methanol-based AV17 and AY7 delayed the reaction by as much as 1?min. The Takayama test was not very sensitive, therefore, its performance was easily affected by enhancement and negative results were often observed. RSID-Blood tests were largely unaffected by chemical enhancement although a drop in positive results was observed for some of the techniques when compared to positive controls.Using a standard procedure for DNA extraction, all the tested blood samples (before and after enhancement) gave a detectable quantity of DNA and were successfully profiled. Out of the 45 samples processed for DNA profiling, 41 gave full profiles, while the remaining showed allele drop out in one or two loci. 相似文献

Score based procedures for the calculation of forensic likelihood ratios are popular across different branches of forensic science. They have two stages, first a function or model which takes measured features from known-source and questioned-source pairs as input and calculates scores as output, then a subsequent model which converts scores to likelihood ratios. We demonstrate that scores which are purely measures of similarity are not appropriate for calculating forensically interpretable likelihood ratios. In addition to taking account of similarity between the questioned-origin specimen and the known-origin sample, scores must also take account of the typicality of the questioned-origin specimen with respect to a sample of the relevant population specified by the defence hypothesis. We use Monte Carlo simulations to compare the output of three score based procedures with reference likelihood ratio values calculated directly from the fully specified Monte Carlo distributions. The three types of scores compared are: 1. non-anchored similarity-only scores; 2. non-anchored similarity and typicality scores; and 3. known-source anchored same-origin scores and questioned-source anchored different-origin scores. We also make a comparison with the performance of a procedure using a dichotomous “match”/“non-match” similarity score, and compare the performance of 1 and 2 on real data. 相似文献

Over the last two decades, empirical evidence has increasingly supported the view that it is possible to reduce reoffending rates by treating or rehabilitating offenders rather than simply punishing them. In fact, this shift from a punishment to a rehabilitation model is arguably one of the most significant events in modern correctional policy. Criminogenic needs, dynamic risk factors, have been the focus of a considerable amount of research and are viewed as primary intervention targets. Drawing from the correctional, psychological, philosophical, and social policy literature, we distinguish between instrumental and categorical needs. The latter are derived from assumptions about human nature and provide the theoretical grounds for the former, as well as for criminogenic needs. We argue that an enriched concept of needs embedded in the notion of human well being, can provide a coherent conceptual basis for rehabilitation and also avoid the problems apparent in the concept of criminogenic needs. From this perspective, criminogenic needs are usefully construed as the internal and external obstacles associated with need distortion. Therefore, they are directly linked to basic need distortion and the absence of the internal and external conditions necessary for a person to lead a fulfilling life. Finally, we outline a possible framework utilising categorical needs and discuss the clinical and policy implications of our perspective. 相似文献

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high‐performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37°C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7°C, but degraded significantly in inoculated blood at 20 and 37°C. Complete loss occurred within 2 days when incubated at 37°C. The benzisoxazole‐cleaved degradation products for both drugs were identified as 2‐hydroxybenzoyl‐risperidone and 2‐hydroxybenzoyl‐paliperidone utilizing liquid chromatography quadrupole‐time‐of‐flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ. 相似文献

The Tennessee Valley Authority, a federal corporation established by Congress in 1933, is charged with the integrated regional development of the Tennessee Valley's resources, including flood control, navigation, reforestation and proper use of marginal lands, electricity generation, and agricultural and economic development. TVA's early leaders, especially David E. Lilienthal and Gordon R. Clapp, articulated a doctrine of “grass roots democracy” and “decentralization” that protected TVA from rival federal bureaucracies and provided greater flexibility and freedom in carrying out TVA's multi-purpose mission. This doctrine also led to innovations in the professionalization of TVA' s highly skilled and diverse workforce. Clapp, a recognized leader in public administration, promoted employee initiative, easy access to top management, multi-disciplinary teamwork, labor/management collaboration, and partnerships with states and localities that took account of local needs and values. The development of joint cooperative councils and conferences, along with other initiatives, were visible manifestations of this “democratic method of administration.” In the aftermath of Clapp's chairmanship that ended in 1954, TVA placed principal emphasis on expanding its electric power system and moved to a more traditional bureaucratic structure of tight control, accountability, and discipline. The crisis of survival that developed in the 1980s had its roots in a growing isolation, rigidity, and decline of professional excellence that was an outgrowth of this new bureaucracy. The current TVA chairman, Marvin T. Runyon, is leading a recovery effort to restore TVA's competitiveness. This effort recalls the vision and values of “grass roots democracy” and “decentralization” espoused by Clapp and Lilienthal. Although coming to TVA with no prior experience in the public sector, Runyon's emphasis on customer service and satisfaction, quality products, teamwork, creative problem solving, employee empowerment, and being “the best” recalls the professionalism and professionalization of the public administrators who led TVA in its early years. 相似文献
