The present study tested the proposition that disengagement of moral self-sanctions enables prison personnel to carry out the death penalty. Three subgroups of personnel in penitentiaries located in three Southern states were assessed in terms of eight mechanisms of moral disengagement. The personnel included the execution teams that carry out the executions; the support teams that provide solace and emotional support to the families of the victims and the condemned inmate; and prison guards who have no involvement in the execution process. The executioners exhibited the highest level of moral, social, and economic justifications, disavowal of personal responsibility, and dehumanization. The support teams that provide the more humane services disavowed moral disengagement, as did the noninvolved guards but to a lesser degree than the support teams.  相似文献

National Crime Survey (NCS) data yield an estimate that 171,000 Americans were nonfatally shot in criminal assaults, robberies, and rapes for the period 1973–1979. Comparing this estimate with the number of firearms homicides during this period suggests either that the death rate in gunshot cases is very high (over 1/3) or that the NCS estimate is low. Based on police-generated data appropriate to estimating the true death rate from gunshot wounds, it appears that the NCS estimate is low by a factor of about 3.0 compared with the number of criminal gunshot woundings known to the police. It is common knowledge that survey-based estimates of assault rates tend to be relatively unreliable, a fact that has been attributed to problems with respondents being willing and able to recall threats, fist fights, and other minor assaults. The current result indicates that the estimation problem is not limited to minor assaults. There is reason to think that the underestimate of gunshot woundings is the result of problems with the NCS sample as well as problems with respondent cooperation.  相似文献

Detection and correct classification of gasoline is important for both arson and fuel spill investigation. Principal component analysis (PCA) was used to classify premium and regular gasolines from gas chromatography-mass spectrometry (GC-MS) spectral data obtained from gasoline sold in Canada over one calendar year. Depending upon the dataset used for training and tests, around 80-93% of the samples were correctly classified as either premium or regular gasoline using the Mahalanobis distances calculated from the principal components scores. Only 48-62% of the samples were correctly classified when the premium and regular gasoline samples were divided further into their winter/summer sub-groups. Artificial neural networks (ANNs) were trained to recognise premium and regular gasolines from the same GC-MS data. The best-performing ANN correctly identified all samples as either a premium or regular grade. Approximately 97% of the premium and regular samples were correctly classified according to their winter or summer sub-group.  相似文献

The extent and use of technology in the British criminal justice system is uneven. Two areas are examined; first where technology is used in prisons or by the police, and secondly when it is used to develop new sanctions, as with electronic monitoring, or as attachments to existing sanctions such as drug testing. Technology in prisons is mainly in the form of perimeter security, and in the police through CCTV cameras or databases. In the second the emphasis is on tracker systems which gives the supervisor greater control. Technological development in criminal justice is not without its critics. Some regard existing technological developments with suspicion, seeing them as a means of enhancing control, or as an attack on traditional liberal values, or more importantly as an extension of a form of behaviourism which is concerned only with the observable act. Others note the expensive failures of technology where systems fail to work or are delivered late. It is suggested a Government study is required to examine existing technologies and its likely future impact whether on the criminal justice system generally or on those working within it or as inmates.  相似文献

A political party's members are its ambassadors in the wider community. Based on a survey of Labour party members in Nuneaton, this article investigates the extent to which party members qua party members are visible amongst their friends and colleagues. It finds that there are few closet Labour party members. Most are known to friends and (slightly less commonly) colleagues. Party members also articulate a political message, discussing politics with friends and work colleagues. Around half of party members believe that they influence others as a result of their discussions; of those who are asked their opinions by friends, almost three-quarters believe that they influence others. Labour party members in Nuneaton are thus a visible and articulate manifestation of the party. The article ends by considering whether this is likely to be true in other constituencies, for other parties, and at other times.  相似文献
