This study presents a number of pseudo-operational trials on plastic bags investigating the double- and co-fuming process of a one-step fluorescent cyanoacrylate (LumicyanoTM) in comparisons with the two-step process with basic yellow 40 (BY40) staining for the detection of latent fingermarks. The results demonstrate that both Lumicyano solution and dye contribute to the increased detection of latent fingermarks during the double-fuming process (trial 1). Co-fuming the Lumicyano solution and dye separately (at a concentration of 8%) but simultaneously was less effective than 8% Lumicyano (trial 2). Co-fuming Lumicyano 8% and an additional 8% Lumicyano dye by weight was more effective than Lumicyano 8% (trial 3), possibly due to increased fluorescent material deposition during co-fuming allowing for better visualization. The use of BY40 after Lumicyano resulted in a considerable increase in detected fingermarks. 相似文献

Public-sector mental health systems have set forth specialized practice competencies for forensic mental health clinicians conducting court-ordered examinations. This study examined a sample of feedback letters to clinicians who submitted mid-training and final reports for review as part of the requirements for certification as a juvenile court clinician. The most common feedback points were insufficient/irrelevant historical data, problems with clarity/organization of the report, problems with interview/mental status examination, and problems with competency to stand trial data/opinions. Clinicians had fewer deficiencies in their final report compared to their mid-training report, supporting the perspective that forensic training and supervision is associated with better quality reports. 相似文献

Motivational interviewing (MI) is a communication style focused on enhancing clients’ own motivation towards change. In the justice system MI has evidence to support that it enhances communication and change behaviors in youth. As most MI training is designed for healthcare settings training and implementation of MI must be adapted to fit the juvenile justice model. This includes both rehabilitation and restorative justice. Here we describe the details that allowed one county small county in Pennsylvania to roll out MI training and initial skills review in less than 6 months. The case reviews the details of planning, trainings, and timing of activities. We then discuss what elements of those details fit into a greater implementation plan that may be applied elsewhere. Four key elements were instrumental to implementation: 1) appreciation of JPO time constraints, 2) cost containment 3) using blending to enhance JPO flexibility with MI use, and 4) policies that normalize use of MI. This outline may assist other courts in their own implementation efforts. 相似文献

The study has two main purposes. First, the study explores core ethical values and behaviors from the perspective of Thai public service organizational leaders. Second, the study investigates the extent to which public sector leaders in Thailand consider Buddhist-based mindfulness practice to be a potentially effective mechanism for reinforcing core ethical values and behaviors in the public sector in Thailand. Using interview data derived from in-depth semi-structured interviews with 12 senior public sector officials in Thailand, the analysis elicits four dimensions of core ethical values and behaviors that are perceived by Thai public service organizational leaders as central to ethical behavior in the public sector. The study also sheds light on the interviewees' positive perceptions towards mindfulness and the role its associated practices can play in promoting ethical decision making and behavior in the public sector in Thailand. 相似文献

Concerns over the unethical conduct of leaders and public officials have led to the renaissance of interest in public service ethics and values. Although national and organizational systems and structures have been instituted to either eradicate or ameliorate unethical behaviours in the public service of countries, the practice still persists with devastating consequences. As one way forward, spirituality has been touted as having the potential of stimulating the moral thoughts of individuals who are dealing with ethical issues, thereby reducing unethical behaviour and generating positive organizational behaviour. Drawing from the perspectives of developing and transitional countries, this special issue empirically examines the extent to which ethics, values and spirituality can reduce unethical behaviours. 相似文献

In many European democracies, political punditry has highlighted the attempts of political parties on the left to court the ‘lavender vote’ of lesbian, gay and bisexual individuals. This article examines the presence of a gay vote in Western Europe with a focus on assessing the role of sexuality in shaping individuals’ political preferences and voting behaviour. Empirically, the effect of sexuality on both ideological identification as well as party vote choice is analysed. Using a cumulative dataset of eight rounds of the European Social Survey between 2002 and 2017, this article demonstrates that partnered lesbians and gay men are more likely than comparable heterosexuals to identify with the left, support leftist policy objectives and vote for left-of-centre political parties. The analysis represents the first empirical cross-national European study of the voting behaviour of homosexual individuals and sheds new light on the importance of sexuality as a predictor of political ideology and voting behaviour within the Western European context. 相似文献

Dual-credit courses expose high school students to college-level content and provide the opportunity to earn college credits, in part to smooth the transition to college. With the Tennessee Department of Education, we conduct the first randomized controlled trial of the effects of dual-credit math coursework on a range of high school and college outcomes. We find that the dual-credit advanced algebra course alters students’ subsequent high school math course-taking, reducing enrollment in remedial math and boosting enrollment in precalculus and Advanced Placement math courses. We fail to detect an effect of the dual-credit math course on overall rates of college enrollment. However, the course induces some students to choose four-year universities instead of two-year colleges, particularly for those in the middle of the math achievement distribution and those first exposed to the opportunity to take the course in eleventh rather than twelfth grade. We see limited evidence of improvements in early math performance during college. 相似文献
