Scales for photography provide a geometrical reference in the photographic documentation of a crime scene, pattern, or item of evidence. The ABFO No. 2 Standard Reference Scale (1) is used by the forensic science community as an accurate reference scale. We investigated the overall accuracy of the major centimeter graduations, internal/external diameters of the circles, error in placement of the circle centers, and leg perpendicularity. Four vendors were selected for the scales, and the features were measured on a vision‐based coordinate measurement system. The scales were well within the specified tolerance for the length graduations. After 4 years, the same scales were measured to determine what change could be measured. The scales demonstrated acceptable stability in the scale length and center‐to‐center measurements; however, the perpendicularity exhibited change. The study results indicate that scale quality checks using certified metal rulers are good practice. 相似文献

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

Validation of Tool Mark Comparisons Obtained Using a Quantitative,Comparative, Statistical Algorithm
L. Scott Chumbley Ph.D. Max D. Morris Ph.D. M. James Kreiser B.S. Charles Fisher B.S. Jeremy Craft M.S. Lawrence J. Genalo Ph.D. Stephen Davis B.S. David Faden B.S. Julie Kidd M.S. 《Journal of forensic sciences》2010,55(4):953-961
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

Geopolitics is increasingly seen by scholars as occurring in everyday spaces and performed by ordinary people. This paper extends this idea to historical work to examine how citizens themselves (re)produce geopolitics at the time of historical events. It does so through a case study of geopolitical tension on the Chile-Peru border in the 1970s. Through oral histories and newspaper analysis, a historical everyday geopolitics approach reveals how those living in the Chilean border city of Arica played a part in promoting national and border security. This centres the embodied and emotional experiences of those affected by violence and conflict. 相似文献

This article seeks to bring more nuance to recent discussions about the role of faith in religious development NGOs. It takes an in-depth look at Tearfund, a leading Evangelical development NGO, and explores the ways in which faith shapes its conceptualisation of development, its programme design, and its implementation strategy. The article traces the process through which Tearfund actively sought to bring faith into the centre of its development work, and argues that grappling with faith in this way can lead religious development NGOs to innovate new approaches to development that are at least somewhat outside of mainstream development thinking. 相似文献
