The optical and morphological properties of resveratrol were investigated. This nontoxic fluorescent natural material, emitting in the visible blue light, was used as an optical marker, enabling the enhancement of the image contrast coming from relief pictures marked on challenging surfaces. By applying appropriated imaging softwares, this marker was verified to be very useful in the latent fingerprint recognition deposited on different wood surface types, mainly those with high level of roughness, where conventional forensic materials do not allow effective fingerprint image visualization.  相似文献

受欺凌青少年向父母保持"沉默",隐瞒被欺凌经历的现象十分普遍。本文从代际情感互动视角出发,通过网络民族志和深度访谈发现,当子代向亲代部分或全部披露欺凌事件,亲代继续实践日常情感互动模式会产生"虚假情感理解"甚至对子代进行身体惩罚,此外长时间的不良代际情感互动会导致受欺凌子代产生负面预期,为避免痛苦"再生产",理性的个体以向亲代保持"沉默"来进行自我保护。代际情感共同体建构是受欺凌子代实现共有感受期望的前提,代际情感互动的时空界限是真实理解受欺凌子代情感需求的基础,消解或转移受欺凌子代负性情感是打破沉默的关键,进而有助于家长理性参与校园欺凌干预,防范校园欺凌风险。  相似文献

Abstract

This study applies moral foundations theory to capital juror decision making. We hypothesized that binding moral foundations would predict death qualification and punitive sentencing decisions, whereas individualizing moral foundations would be associated with juror disqualification and a leniency effect. Additionally, we considered whether moral foundations can explain differences in death penalty application between conservatives and liberals. Respondents from two independent samples participated in a mock-juror task in which the circumstances of a hypothetical defendant’s case varied. Results revealed moral foundations were strong predictors of death qualification. The binding and individualizing foundations were related to sentencing decisions in the expected ways. Supporting our contention that moral foundations operate differently across different types of cases, heterogeneity in the effects of moral foundations was observed. Finally, we found support for the hypothesis that the relationship between sentencing decisions and conservatism would be attenuated by moral foundations.  相似文献

ABSTRACT

This research analyses disciplinary decisions of the New Zealand Lawyers and Conveyancers Disciplinary Tribunal (NZLCDT) from 2011 to 2017 that involve vulnerable clients. Increasingly, scholarship discusses vulnerability as an ethical concept, including in the legal context. Based on published decisions, the present study inquires whether some legal clients’ vulnerability warrants special attention. Twenty-five of the 193 clients in the NZLCDT decisions qualified as vulnerable based upon age, gender, mental health/neuro-disability or immigrant status. The results may inform disciplinary bodies and inspire preventive strategies by lawyers, educators and regulatory bodies. Ultimately, this evidence-based analysis magnifies the importance of client-centred approaches to risk reduction in legal practice.  相似文献

In response to research demonstrating that irrelevant contextual information can bias forensic science analyses, authorities have increasingly urged laboratories to limit analysts' access to irrelevant and potentially biasing information (Dror and Cole (2010) [3]; National Academy of Sciences (2009) [18]; President's Council of Advisors on Science and Technology (2016) [22]; UK Forensic Science Regulator (2015) [26]). However, a great challenge in implementing this reform is determining which information is task-relevant and which is task-irrelevant. In the current study, we surveyed 183 forensic analysts to examine what they consider relevant versus irrelevant in their forensic analyses. Results revealed that analysts generally do not regard information regarding the suspect or victim as essential to their analytic tasks. However, there was significant variability among analysts within and between disciplines. Findings suggest that forensic science disciplines need to agree on what they regard as task-relevant before context management procedures can be properly implemented. The lack of consensus about what is relevant information not only leaves room for biasing information, but also reveals foundational gaps in what analysts consider crucial in forensic decision making.  相似文献

The decision to go to war in Australia remains the prerogative of the Executive. The lack of parliamentary authorisation of perhaps the most significant decision a democracy can make has seen sustained, but unsuccessful, efforts to reform legislation. In the wake of the costly invasion and occupation of Iraq in 2003, repeated calls for legislative reform of Australia's war powers have failed to find traction amongst Coalition and Australian Labor Party (ALP) leadership. Lamenting the lack of transparency and accountability in the current system, those favouring legislative reform would see authorisation of combat missions placed in the hands of Parliament. However, given the lack of support from either of the major parties, any legislative reform remains unlikely. Given this impasse, this article argues that a compromise option, in the form of a new war-powers convention, may be a small step towards democratising the decision of going to war. While not legally binding, this constitutional convention would represent an agreement by the major parties that overseas combat operations will be properly debated in Parliament.  相似文献

Sport's transformative potential is known to support marginalised children, to deal with traumatic experiences and instil positive values; yet hosting mega sporting events (MSEs) can have negative impacts. Drawing on participatory research with favela‐based children during the 2014 World Cup in Brazil, this article argues that MSEs bring a macro‐securitisation of urban life, which causes considerable harm. This paper also suggests that the inclusion of children's voices in advocacy debates can challenge top‐down securitisation and might allow MSEs to foster further positive social transformation. Therefore, juxtaposed with causing harm, macro‐securitisations can open opportunities for children to take action and have their voices heard.  相似文献
