The deterioration of police/citizen relations has had a major impact on the administration of justice. Mutual suspicion, hostility, distrust, and fear have resulted in minimal citizen cooperation and, consequently, an increase in police use of aggressive enforcement procedures. These procedures adversely affect the police as well as the citizenry. Use of aggressive enforcement has two salient consequences: it isolates the police from the citizen, and it generates occupational solidarity among police personnel. Solidarity subsequently increases police/citizen polarization. The process, thus, is circular. The purpose of this study is to empirically investigate the determinants of social isolation and occupational solidarity.To investigate these determinants, a multivariate, multistage conceptual model was developed and analyzed. The findings suggest that the conceptual model, save two minor modifications, fits the data. Policy implications based on these findings are presented and discussed. 相似文献

We examine how political campaigns influence individuals’ levels of correct, incorrect, and don’t know responses and the gender gap in political knowledge during the 2000 American presidential campaign. Using data from the 2000 National Annenberg Election Survey (NAES), we demonstrate that as the campaign progresses the electorate provides more correct answers and fewer incorrect answers. Moreover, the political campaign significantly reduces (and possibly eliminates) the direct effect of sex on political knowledge. While the political campaign decreases the number of incorrect answers provided by both men and women, the number of correct answers provided by women increases. Our findings highlight the importance of the political campaign in determining relative levels of political knowledge for men and women. 相似文献

The distinction between perimortem and postmortem fractures is an important challenge for forensic anthropology. Such a crucial task is presently based on macro‐morphological criteria widely accepted in the scientific community. However, several limits affect these parameters which have not yet been investigated thoroughly. This study aims at highlighting the pitfalls and errors in evaluating perimortem or postmortem fractures. Two trained forensic anthropologists were asked to classify 210 fractures of known origin in four skeletons (three victims of blunt force trauma and one natural death) as perimortem, postmortem, or dubious, twice in 6 months in order to assess intraobserver error also. Results show large errors, ranging from 14.8 to 37% for perimortem fractures and from 5.5 to 14.8% for postmortem ones; more than 80% of errors concerned trabecular bone. This supports the need for more objective and reliable criteria for a correct assessment of peri‐ and postmortem bone fractures. 相似文献

Proper interpretation of forensic measurements can be critical to the administration of justice. Breath alcohol testing is commonly relied upon to measure the concentration of alcohol in breath or, indirectly, in blood. The concentration sought constitutes the “quantity intended to be measured,” referred to as the measurand. Although breath tests always probe the same physical quantity, their measurand is dictated by statute and varies between jurisdictions. Thus, identical numerical values obtained from tests in disparate jurisdictions may refer to different quantities and may not indicate the relevant statutory measurand. This can lead to misinterpretation of results, referred to as the “measurand problem.” We first illustrate the concept of the measurand. Thereafter, the measurand problem is illustrated through application of Hlastala's breath test paradigm and Gullberg's work on breath test uncertainty. It is shown that where the measurand is not properly accounted for, conclusions based upon breath test evidence are undermined. 相似文献

Because they are airborne artefacts, drones embody threats to people and property, even in normal operation, but especially when malfunctions occur in equipment or in the data communications on which they are heavily dependent. Some natural controls exist over inappropriate drone behaviour. General liability laws provide remedies for harm that arises from drones, and act as a deterrent against irresponsible behaviour. Specific air safety laws do, or may, apply to drones. Co-regulatory mechanisms provide protections, as may industry and organisational self-regulation. However, a review of current and emergent regulatory arrangements identifies a considerable range of gaps and uncertainties that need to be addressed, particularly in relation to small drones, including micro-drones. 相似文献

One determinant of the success or failure of political revolutions is whether there is a split among the ruling elites. Elite defections in a competitive authoritarian regime can tip the balance in favour of regime change and democratization. This article examines when and why elites defect through the case of Burkina Faso. In October 2014, President Blaise Compaoré of Burkina Faso was forced to step down after 27 years in power and multiple term limits contraventions. We propose a new theory linking growth in democratic attitudes at the grassroots to elite defection from hegemonic parties. We argue that a broad increase in popular democratic attitudes can both decrease the costs and increase the benefits of elite defection, creating conditions that enable elites to rescind their loyalty to the regime. We support this argument with interviews with ruling-party defectors in Burkina Faso and two rounds of Afrobarometer survey data. Our findings demonstrate that democratic attitudes can grow under competitive authoritarian regimes, and that these citizen attitudes can impact regime change by increasing the likelihood of elite defection. 相似文献
