Proficiency testing is a key component of quality assurance programs within crime laboratories and can help improve laboratory practices. However, current proficiency testing procedures contain significant limitations and can be misinterpreted by examiners and court personnel (Garrett & Mitchell, 2018). To evaluate some of these limitations, we surveyed latent print examiners (n = 198) after they completed a Collaborative Testing Services, Inc. proficiency test. Additionally, we evaluated test performance and used a quality metric algorithm to evaluate the quality of test prints. Results do not suggest that respondents are dissimilar to the broader examiner population, although they may engage in different behaviors when completing tests versus casework. Findings show that proficiency testing contains prints of high quality and is perceived as both relatively easy and representative of casework. The test discriminated between inexperienced and experienced respondents, and verification procedures were largely ineffective in reducing errors. Objective quality metrics may provide a path forward to improving proficiency testing in a measurable manner. 相似文献

Decentralization is argued to enhance citizen–government relationships and, thus, to lead to higher levels of citizen trust. General purpose policing encompasses various services that might be assigned to different levels of governments. The literature lacks generalizable studies of the effects of the structural arrangements of police systems on police performance. This study is a cross‐national exploration of the relationship between the varying degrees of police decentralization and police performance as measured by citizen trust in the police. It uses a measure of decentralization of police systems based on the tiers of government with some control over police. Results show that, in the 72 sample countries, the relationship between citizen trust in police and decentralized police systems is not statistically significant. However, when the countries are categorized by the Human Development Index, decentralized police systems tend to be positively related to citizen trust in the more developed countries but inversely in the less developed countries. 相似文献

Cognitive learning theory of delinquency proposes mat as a result of early negative conditioning, particularly in the family and school settings, at-risk youth are more apt to develop an insecure, alienated belief system which increases the likelihood that they will perceive the world as a hostile place where their fate is in the hands of outside circumstances. According to the cognitive perspective, as the at-risk level of youth increases, their world view or locus of control will tend to become more external. The present study tests this proposition by investigating the relationship of at-risk level to locus of control for a sample of 196 juvenile shoplifters. The study utilizes an at-risk scale developed by the author and the Nowicki-Strickland Locus of Control Scale for Children. Results generally confirm the hypothesis that level of risk is positively related to an external locus of control. Ways to reverse the cumulative process of learned insecurity and perceived alienation are discussed. 相似文献

The analysis of parliamentary debates is at the confluence of a number of developments in political science. What light can automated and semi‐automated techniques throw on such analysis? In this paper we compare two such approaches, one semi‐automated (Hamlet) and the other fully automated (Alceste). We use both approaches to identify the prominent themes in debate and to assess how far speakers who favour different positions adopt a distinct pattern of discourse. We seek to assess how far the two approaches yield convergent or divergent analyses. Selecting a second reading debate from the UK House of Commons on a private member's bill on abortion in July 1966, we are able to show similarities of analysis despite the detailed differences between the two approaches. In particular, the analysis in Hamlet al.lows identification of the extent to which individual speakers employ one type of vocabulary rather than another. Alceste is able to provide a statistical basis for the different classes of vocabulary that occur in the debate. However, the two programs rest upon quite different assumptions about the relationship between syntax and meaning, with implications for the practice of political science. 相似文献

What are the differences between “women's prisons” and “men's prisons”? That question is answered in this article, which documents that many institutions “for” women do not provide services designed specially for women, or anyone else. Moreover, some women's prisons provide fewer vocational, recreational, and educational programs than do institutions “for” men. Given the growing literature on the disparity of services and on the relative deprivations faced by many women prisoners, the author questions whether segregation by sex should continue to be used as a major premise of prison classification systems. 相似文献
