Many observers describe prison subcultures as inherently and irredeemably antisocial. Research directly ties prison subcultures to violence, gang membership, and poor reintegration. In extreme cases, research has also suggested that prison subcultures contribute to incarcerated people joining radical groups or embracing violent extremist beliefs. These claims, however, ignore key differences in the larger cultural and social context of prisons. We examine the relationship between prison subcultures and prison radicalization based on semistructured qualitative interviews with 148 incarcerated men and 131 correctional officers from four western Canadian prisons. We outline several imported features of the prison subculture that make incarcerated people resilient to radicalized and extremist messaging. These features include 1) national cultural imaginaries; 2) the racial profile of a prison, including racial sorting or a lack thereof; and 3) how radicalization allowed incarcerated men and correctional officers to act outside the otherwise agreed-to subcultural rules. Our research findings stress the importance of contemplating broader sociocultural influences when trying to understand the relationship between radicalization and prison dynamics and politics. 相似文献

Research Summary
The Kansas City Preventive Patrol Experiment (KCPPE) was seen by its developers to have produced “consistent evidence of the lack of effects of any consequence on crime,” a conclusion that was to have a strong impact on assumptions about police patrol for almost half a century. We identified the original official crime data from the KCPPE, and reanalyzed outcomes focusing on a comparison of the “proactive” versus “control” beats (“reactive beats” were criticized because of violations of treatment integrity); examining broad categories of crime (to increase statistical power); and using count regression models. Our findings are not unequivocal, but point to modest impacts of police patrol on crime in police beats.Policy Implications
Our findings suggest that lessons drawn for half a century from the KCPPE need to be revisited. The KCPPE does not show that police patrol in large areas has no influence on crime, and this finding is consistent with several more recent studies. At the same time, we note that the effects of patrol in the KCPPE using our analysis strategy, and those found in other studies of preventive patrol in larger areas, are about half that found in hot spots policing studies. This suggests that police agencies ideally should invest in focused hot spots policing initiatives. However, absent an ability to manage such initiatives, or the crime analysis capabilities to identify crime hot spots routinely, simpler preventive patrol schemes to utilize uncommitted patrol time can be seen as potentially effective in preventing crime. 相似文献196.

This paper makes an original contribution to human–animal studies through the application of social construction theory to an iconic species of Australian snake, the coastal taipan. Little research attention using this approach has been focused on reptiles, and this study addresses this gap in the literature. The taipan has achieved a high level of notoriety in Australia. This paper seeks to understand why and how this has occurred. Drawing on a range of data derived from analysis of newspaper articles, popular magazines and books, and the scientific literature, four dominant narratives are identified: the taipan as an object of science and natural history, as social problem, as object quest and as celebrity. The insights gained from this study support the contention that the meanings made of Australia's fauna are fluid, historically contextualised and socially constructed. In the specific case of the taipan, key individuals, including scientists, popular natural historians and snake men contributed greatly to the species’ construction, as did popular cultural forms such as newspapers and natural history books. 相似文献

Burned skeletal material is often very fragile and at high risk for fragmentation during packaging and transportation. One method that has been suggested to protect bones in these cases is to carefully wrap them in aluminum foil. Traces of aluminum, however, are known to transfer from foil packaging materials to food products. If such transfer occurs between aluminum foil and bones, it could interfere with subsequent chemical, elemental and isotopic analyses, which are becoming more common in forensic anthropological investigations. This study examined aluminum levels in bones prior to and following the use of aluminum foil packaging and storage for a 6‐week period. Results indicate no significant change in the detected levels of aluminum (p > 0.05), even when packaged in compromised foil and exposed to elevated temperatures. Aluminum foil can therefore continue to be recommended as a packaging medium without affecting subsequent chemical examinations. 相似文献

This study investigated the association between family violence and the attributions made for negative partner behaviors in an Australian context. Three groups of men were classified as physically violent (in counseling), non-physically violent (in counseling), and non-physically violent (in the community). The Relationship Attribution Measure was used to assess the attributional dependent variables of locus, stability, globality, intent, motivation, and blame. Significant differences between violent and nonviolent men on each of the attributional dimensions were found. Physically violent men were more likely than non-physically violent men (counseling) to attribute the negative behavior of their partners to unchangeable, intentional rather than unintentional, selfishly motivated, and blameworthy causes. However, these differences disappeared when marital satisfaction was controlled. The implications of this work for domestic violence intervention programs are discussed, along with a number of methodological issues and directions for future research. 相似文献
