Abstract: An online forensic dental identification exercise was conducted involving 24 antemortem–postmortem (AM–PM) dental radiograph pairs from actual forensic identification cases. Images had been digitally cropped to remove coronal tooth structure and dental restorations. Volunteer forensic odontologists were passively recruited to compare the AM–PM dental radiographs online and conclude identification status using the guidelines for identification from the American Board of Forensic Odontology. The mean accuracy rate for identification was 86.0% (standard deviation 9.2%). The same radiograph pairs were compared using a digital imaging software algorithm, which generated a normalized coefficient of similarity for each pair. Twenty of the radiograph pairs generated a mean accuracy of 85.0%. Four of the pairs could not be used to generate a coefficient of similarity. Receiver operator curve and area under the curve statistical analysis confirmed good discrimination abilities of both methods (online exercise = 0.978; UT‐ID index = 0.923) and Spearman’s rank correlation coefficient analysis (0.683) indicated good correlation between the results of both methods. Computer‐aided dental identification allows for an objective comparison of AM–PM radiographs and can be a useful tool to support a forensic dental identification conclusion. 相似文献

Israel's enactment of national health insurance was clearly a breakthrough. However, other aspects of reform that were supposed to be implemented simultaneously were stymied, in particular, the conversion of government hospitals to independent trusts and removing the Ministry of Health from the direct provision of services such as mental health and long-term care. This article explores how punctuated equilibrium and path dependency coexist in the Israeli case. In doing so, it examines the relevance of concepts provided by various theories of social and institutional change. Aside from path dependency and punctuated equilibrium, we discuss other notions derived from related theories, such as political leadership and the role of ideas. Applying these theories to the Israeli case helps better understand the coexistence of punctuated equilibrium and path dependency. 相似文献

Despite the salience of health disparities in media and policy discourse, little previous research has investigated if imagery associating an illness with a certain racial group influences public perceptions. This study evaluated the influence of the media's presentation of the causes of type 2 diabetes and its implicit racial associations on attitudes toward people with diabetes and preferences toward research spending. Survey participants who viewed an article on genetic causation or social determinants of diabetes were more likely to support increased government spending on research than those viewing an article with no causal language, while participants viewing an article on behavioral choices were more likely to attribute negative stereotypes to people with diabetes. Participants who viewed a photo of a black woman accompanying the article were less likely to endorse negative stereotypes than those viewing a photo of a white woman, but those who viewed a photo of a glucose-testing device expressed the lowest negative stereotypes. The effect of social determinants language was significantly different for blacks and whites, lowering stereotypes only among blacks. Emphasizing the behavioral causes of diabetes, as is common in media coverage, may perpetuate negative stereotypes. While drawing attention to the social determinants that shape these behaviors could mitigate stereotypes, this strategy is unlikely to influence the public uniformly. 相似文献

In this article, I examine the sources of our modern idea of human ‘character' and its availability for ‘reading' in early modern English, tracing the evolution of the word through 1755 - the publication date of Samuel Johnson's Dictionary; by this date, the word comprehends most if not all of its current meanings. By exploring the history of the word ‘character' in the early modern period, I hope to reveal some of the ways in which ideas about written signs and texts have been woven into current notions of identity - but not so much our own identities, perhaps, as the identity of others. The purpose of this article is to suggest how the past history of the word ‘character' - its sources in the domain of writing - still animates its present usage and conditions our understanding of who others are or can be. What I will be tracing here, more precisely, is a succession of semantic shifts, or ‘extensions' of the semantic domain, of the word ‘character' over the course of this period. 相似文献

This is an empirical and theoretical examination of high reliability organizations. The empirical referents are the U.S. Navy's nuclear aircraft carriers and the air traffic control system of the U.S. Federal Aviation Administration. Three modes of organizational behavior are observed ranging from routine or bureaucratic to high-tempo to emergency. Each mode has distinctive authority patterns, communications pathways and leadership perspectives. Since 1984, an interdisciplinary group of scholars at Berkeley has been involved in making observations of and theorizing about “high reliability organizations” (HROs), which operate technical systems that are very beneficial, costly, and hazardous. Major operational errors in these organizations are likely to produce catastrophic consequences; therefore, HROs take on the dual goals of sustaining delivery at maximum capacity and operating in nearly error-free fashion. They are so effective that the probability of serious error is very low. Other kinds of organizations systematically use trial-and-error learning. HROs, however, have less confidence in this process for conducting hazardous operations, because their next error may be their last trial. This paper draws on experience with two of the Navy's nuclear aircraft carriers and the Federal Aviation Administration's air-traffic control system. Current theories derive primarily from studies of “failure-tolerant,” trial-and-error operating bureaucracies. Is this literature a sure guide to HROs? Do the phenomena challenge contemporary thinking about complex organizations? “High-reliability” operations reveal a range of theoretical (and operational) surprises. The remainder of this discussion explores a single dimension of this theoretical arena. 相似文献

Research Summary Over the past two decades, researchers have been increasingly interested in measuring the risk of offender recidivism as a means of advancing public safety and of directing treatment interventions. In this context, one instrument widely used in assessing offenders is the Level of Service Inventory‐Revised (LSI‐R). Recently, however, the LSI‐R has been criticized for being a male‐specific assessment instrument that is a weak predictor of criminal behavior in females. Through the use of meta‐analytic techniques, we assessed this assertion. A total of 27 effect sizes yielded an average r value of .35 ([confidence interval] CI = .34 to .36) for the relationship of the LSI‐R with recidivism for female offenders (N= 14,737). When available, we also made within‐sample comparisons based on gender. These comparisons produced effect sizes for males and females that were statistically similar. Policy Implications These results are consistent with those generated in previous research on the LSI‐R. They call into question prevailing critiques that the LSI‐R has predictive validity for male but not for female offenders. At this stage, it seems that corrections officials should be advised that the LSI‐R remains an important instrument for assessing all offenders as a prelude to the delivery of treatment services, especially those based on the principles of effective intervention. Critics should be encouraged, however, to construct and validate through research additional gender‐specific instruments that revise, if not rival, the LSI‐R. 相似文献
