This research examines the utility of patella outline shape for matching 3D scans of patellae to knee radiographs using elliptical Fourier analysis and subjective methods of human visual comparison of patellae across radiographs for identification purposes. Repeat radiographs were captured of cadaver's knees for visual comparison before patellae were extracted and skeletonized for quantitative comparisons. Quantitative methods provided significant narrowing down of the candidate pool to just a few potential matches (<5% of original sample), while the human analysts showed high capacity for correctly matching radiographs, irrespective of educational level (positive predictive value = 99.8%). The successful computerized matching based on a single quantified patella trait (outline shape) helps explain the potency achieved by subjective visual examination. This work adds to a growing body of studies demonstrating the value of single isolated infracranial bones for human identification via radiographic comparison.  相似文献

Law enforcement personnel (LEP) use a variety of tactics to perform their job duties. Although LEP often receive specialized training to work with ethnocultural minorities and are sometimes trained to work with lesbian, gay, bisexual, transgender, and queer (LGBTQ) citizens, a clear articulation of LGBTQ-affirming police tactics has not yet been established. Using qualitative content analysis and a multiple case study approach, this project identified a variety of tactics generated by LEP in written surveys and group discussion of scenarios involving LGBTQ citizens. Results showed that across all scenarios, LEP were able to generate LGBTQ-affirming tactics, including both typical police procedures, as well as approaches specific to LGBTQ citizens. Non LGBTQ-affirming tactics typically reflected reluctance to adapt general procedures to meet the needs of LGBTQ citizens. The results of this study support the use of group-based scenario training to help LEP identify and adopt LGBTQ-affirming approaches. This study is significant because it represents a first step toward identifying best practices for LGBTQ-affirming police tactics.  相似文献

Analyzing newspaper coverage of the 1998 Nairobi and 2002 Mombasa terrorist attacks by the Nairobi Daily Nation and East African Standard finds that generalizations from Western sources, such as newsworthiness criteria and coverage of government officials and terrorists, appear similar in Kenyan media, although interpretation of the attacks were colored by a “developing world” perspective in some respects. Terrorists also ironically are more prominent in subsequent attacks, although perhaps only when they fail to inflict heavy damage and casualties. The second attack also brought far more criticism on the Kenyan government, which may have implications for similar events in other countries.

ABSTRACT

The performing arts sector of the Czech Republic faces significant challenges twenty-five years after the Velvet Revolution, which ushered in swift and dramatic political, social, and economic change. Early policy decisions, subsequent privatization efforts, and neglect, compounded by the country's foray into the muddy waters of the free market, have left artists and administrators seeking solutions and searching for solvency. Empirical research, primarily in the form of surveys, site visits, and interviews with prominent Czech artists and administrators, significantly informs this article, which explores the state of Czech performing arts twenty-five years after the fall of Communism.  相似文献

This article explores public sector responsiveness to voter‐led initiatives, specifically, the degree to which public managers attempt to lock in resources before they are constrained by a particular initiative. The authors posit that such behavior, which they term “beating the clock,” is a function of the potential impact of the proposed initiative, the degree to which managers can react to the initiative's central issues, and the perceived likelihood of passage. Although scholars have explored different responses to voter‐led initiatives, this particular form of strategic behavior has yet to be studied. Using longitudinal data on public debt issuance, hypotheses are tested in the context of a reform proposed through the initiative process in Colorado in 2010. Results show that the number of debt issues increased by roughly 150 percent in advance of a potentially binding election, indicating the ability to preempt formal initiative efforts in certain policy areas.  相似文献

ABSTRACT

Contemporary conceptions of written organizational rules evoke images of inefficiency, constraint, and rigidity. While formal rules can generate negative outcomes, this article argues that their written nature is not the culprit. Rather, theory suggests that the formalization process increases a rule's likelihood of becoming effective “green tape.” From a rule design perspective, rule formalization is expected to trigger more organizational learning and greater scrutiny than unwritten rules, which undergo no such process. From a compliance perspective, written rules are expected to focus organizational attention and convey legitimacy better than unwritten rules, thereby increasing the likelihood of compliance. Combining these expectations, the article hypothesizes that written rules will exhibit more logical designs, higher compliance, and ultimately greater effectiveness than unwritten rules. Statistical modeling of two data sources supports these expectations and suggests the need to rethink reflexively negative attitudes toward written organizational rules.  相似文献

ABSTRACT

This article addresses previous shortcomings in diversity management scholarship by testing an expanded diversity model borrowed from the work of Page (2007 Page , S. E. 2007 . The Difference: How the Power of Diversity Creates Better Groups, Firms, Schools, and Societies . Princeton , NJ : Princeton University Press . [Google Scholar]). Page's model assumes diversity can be measured as both a mean and a variance, and that it consists of cognitive, identity, and preference characteristics. We link Page's conceptualization of diversity to both individual-level outcomes and organizational performance. Results indicate cognitive, preference, and identity diversity have either no or small, mixed effects on employee turnover intentions and agency performance; instead, findings suggest employee voice and organizational size and structure matter more than diversity in our sample. We conclude with a discussion of the theoretical ramifications of our findings.  相似文献

Following the 1997 Asian financial crisis, the regulatory system involving governance of the corporate sector was subjected to major legislative and institutional reforms, primarily in response to exposures of serious cases of corruption and abuse in the financial sector by well-connected businesspeople. However, the 2008 global financial crisis indicated continued occurrence of irresponsible forms of corporate development and practices, underscoring structural weaknesses within the regulatory system in spite of these reforms. This article argues that the reforms that had been introduced ignored how state-business nexuses shape the way firms operate, a core reason for the persistence of unproductive and speculative forms of corporate development, grand corruption and cronyism. Utilising Malaysia as a case study, this article indicates that institutional reforms involving devolution of power to regulatory institutions are imperative to provide them with the autonomy to objectively institute prudential controls and indict errant firms that violate legislation overseeing corporate activities.  相似文献

The mandatory bid rule has its origins in the UK and now applies throughout the EU and in many other jurisdictions. Under a mandatory bid, an acquirer of a controlling stake in a listed company has to offer to the remaining shareholders a buy‐out of their minority stakes at a price equal to the consideration received by the incumbent controller. While the rule warrants that no value‐destroying control transfers take place, it is often criticised for preventing value‐increasing transactions. This paper challenges some of the claims made by critics of mandatory bids. Highlighting the effects of synergy gains in private sale‐of‐control transactions, it is shown that mandatory bids prevent inefficient control transfers, where minority shareholder protection rules provide inadequate protection. Furthermore, mandatory bids help facilitate transfers to the most efficient bidders in multi‐bidder settings. The mandatory bid is justifiable, on economic grounds, in wider circumstances than is commonly assumed by law and economics scholars.  相似文献

The field of firearms and toolmark analysis has encountered deep scrutiny of late, stemming from a handful of voices, primarily in the law and statistical communities. While strong scrutiny is a healthy and necessary part of any scientific endeavor, much of the current criticism leveled at firearm and toolmark analysis is, at best, misinformed and, at worst, punditry. One of the most persistent criticisms stems from the view that as the field lacks quantified random match probability data (or at least a firm statistical model) with which to calculate the probability of a false match, all expert testimony concerning firearm and toolmark identification or source attribution is unreliable and should be ruled inadmissible. However, this critique does not stem from the hard work of actually obtaining data and performing the scientific research required to support or reject current findings in the literature. Although there are sound reasons (described herein) why there is currently no unifying probabilistic model for the comparison of striated and impressed toolmarks as there is in the field of forensic DNA profiling, much statistical research has been, and continues to be, done to aid the criminal justice system. This research has thus far shown that error rate estimates for the field are very low, especially when compared to other forms of judicial error. The first purpose of this paper is to point out the logical fallacies in the arguments of a small group of pundits, who advocate a particular viewpoint but cloak it as fact and research. The second purpose is to give a balanced review of the literature regarding random match probability models and statistical applications that have been carried out in forensic firearm and toolmark analysis.  相似文献
