Across occupations of every form, including those in criminal justice, administrators, managers, and supervisors frequently
introduce changes to the structure and/or processes of the work environment. These changes may be seen as necessary to enhance
worker productivity, but may be viewed by some workers as an unwanted disruption to their routines. Should employees interpret
changes in such a manner, they can, and often do, negate these reforms. Employee work orientations (i.e., philosophical approaches
toward work) undoubtedly play a role in such an interchange because they influence both how employees behave on the job and
how they perceive their job. The move toward community-oriented policing constitutes a major paradigm shift to the practice
of law enforcement. This structural and procedural change to the routines of policing could be perceived as threatening to
those law enforcement officers whose work orientations are inconsistent with the philosophical foundation of community-based
policing. The presence of a sufficient number of such officers could doom this movement to failure. This study uses survey
data collected from a sample of sheriff’s deputies involved in an agency-wide community policing effort. In this study we
examine the effects of deputies’ work orientations on their perceptions of the agency’s readiness for and the anticipated
effectiveness of this initiative. The findings suggest interesting differences in the efforts of a traditional crime control
orientation versus a more progressive community service orientation toward policing. 相似文献

Political parties and legislators use legislative debates to establish their reputation, challenge rivals, and engage in coalition management, among many other tasks. Yet, existing theories on parliamentary debates have abstracted away from the need for information and expertise, which are costly to acquire. Drawing on the “informational” perspective on legislative organization, we address this problem by arguing that party leaders use committees as training arenas for their backbenchers. They task their assigned members with acquiring specific expertise and then rely heavily on those members during the corresponding debates. We turn to the Portuguese legislature, from 2000 to 2015, to discuss how saliency, government dynamics, and party size affect the use of experts. We test this theory using a novel approach to classify speeches that leverages the texts of legislation as training data for a supervised approach. 相似文献

Chumbley et al. (2010) described a statistically based algorithm for comparing pairs of tool marks. They presented empirical evidence that the algorithm produces well‐separated similarity score values for “matching” and “non‐matching” pairs of tool marks. However, the algorithm has two substantial weaknesses. First, it is “uncalibrated” in the sense that error rates can be determined only through empirical investigation. Second, it relies on a randomized test and can lead to different similarity scores when the algorithm is repeatedly applied to the same pair of tool marks. We present an improved version of the procedure, which eliminates the randomized scores and yields more consistent and predictable error rate control. This is accomplished by replacement of a random sampling step from the original algorithm with a deterministic process. We demonstrate the improved algorithm and compare its performance to the original by applying to known “matching” and “non‐matching” pairs of tool marks. 相似文献

Validation of Tool Mark Comparisons Obtained Using a Quantitative,Comparative, Statistical Algorithm

Abstract: A statistical analysis and computational algorithm for comparing pairs of tool marks via profilometry data is described. Empirical validation of the method is established through experiments based on tool marks made at selected fixed angles from 50 sequentially manufactured screwdriver tips. Results obtained from three different comparison scenarios are presented and are in agreement with experiential knowledge possessed by practicing examiners. Further comparisons between scores produced by the algorithm and visual assessments of the same tool mark pairs by professional tool mark examiners in a blind study in general show good agreement between the algorithm and human experts. In specific instances where the algorithm had difficulty in assessing a particular comparison pair, results obtained during the collaborative study with professional examiners suggest ways in which algorithm performance may be improved. It is concluded that the addition of contextual information when inputting data into the algorithm should result in better performance. 相似文献

Targeted killings have become a central component of counterterrorism strategy. In response to the unprecedented prevalence of this strategy around the world, numerous empirical studies have recently examined whether “decapitating” militant groups with targeted killings is strategically effective. This study builds on that research program by examining the impact of targeted killings on militant group tactical decision-making. Our empirical strategy exploits variation in the attack patterns of militant groups conditional on whether a government’s targeted killing attempt succeeded against them operationally. In both the Afghanistan-Pakistan and Israel-West Bank-Gaza Strip theaters, targeted killings significantly alter the nature of militant group violence. When their leaderships are degraded with a successful strike, militant groups become far less discriminate in their target selection by redirecting their violence from military to civilian targets. We then analyze several potential causal mechanisms to account for these results and find strongest evidence that targeted killings tend to promote indiscriminate organizational violence by empowering lower level members with weaker civilian restraint. 相似文献

Expectations of Russia becoming a global ‘breadbasket’ have been nurtured by its rise to the top group of global wheat exporters, the abundance of abandoned land, assumed yield gaps and the apparent ‘success’ of agroholdings. It is argued here that becoming a global breadbasket is hindered by substantial costs of re-cultivating abandoned land, management and financial problems of megafarms and agroholdings, lack of infrastructure for exports and increased domestic demand for feed grains as input for the meat sector. Furthermore, as Russian wheat production is extremely volatile it might increase global price volatility, rather than contributing to global food security. 相似文献

In recent years, a growing body of empirical research suggests that indiscriminate violence against civilian targets tends to carry substantial political risks compared to more selective violence against military targets. To better understand why terrorist groups sometimes attack politically suboptimal targets, scholars are increasingly adopting a principal-agent framework where the leaders of terrorist groups are understood as principals and lower level members as agents. According to this framework, terrorist leaders are thought to behave as essentially rational political actors, whereas lower level members are believed to harbor stronger non-political incentives for harming civilians, often in defiance of leadership preferences. We test this proposition with an original content analysis of terrorist propaganda videos. Consistent with the principal–agent framework, our analysis demonstrates statistically that terrorist leaders tend to favor significantly less indiscriminate violence than their operatives actually commit, providing unprecedented insight into the incentive structure of terrorist leaders relative to the rank-and-file. 相似文献

After reviewing developments in human rights law and international law – in particular the domestication of international human rights law and the rise of the democratic norm in international law – the importance of these developments for the Commonwealth and for its member states is highlighted and linked to many of the programmes and policies that the Commonwealth Secretariat has recently launched. This paper discusses these developments and others in order to stress the wealth of potential advantages for Commonwealth member states and their citizens that flow from a common commitment under the rule of law to human rights and democracy. The authors endeavour to show that such wealth is more than mere economic benefit – as important as that undoubtedly is – and that citizens stand to reap a moral system of government, one which expands the opportunities for popular participation in political processes and puts an end to social practices that marginalise some citizens and empower others. 相似文献
