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

ABSTRACTIncreasingly, a diverse set of policy communities, including those with defence, development and environmental mandates, frame climate change as a security threat. Most often this discursive formation labels climate change as a ‘threat multiplier’. This framing, however, is vague, linear and leaves many questions unanswered regarding how institutions can develop and implement policy that addresses the joint challenges of climate change, conflict and security. Utilising a mixed-methods approach, and grounding data collection in US policy communities, this article examines how policy actors and institutions integrate climate-security discourses into policy processes. The objective of this research is to provide direct insight into how the discourses and technical understandings of climate-security transition into policy priorities and implementation realities. This research identified three common approaches to climate-security: (1) A challenge of adaptation and resilience; (2) A potent political argument; and (3) An issue of limited importance and feasibility. These approaches, however, are inconsistent across sectors and within organisations, suggesting a lack of cohesion and considerable challenges in identifying and responding to climate change as a ‘threat multiplier’. 相似文献

The EPA implements its policy of exhaust emission control by setting standards specified in terms of grams of pollutants per mile traveled. As a result, the tax must first restrain the vehicle miles traveled (VMT) if it is to have an impact on emission at all. EPA's choice of miles traveled as the medium through which its policy of pollution control must run is unfortunate, because travel is an activity that people resist giving up. This is reflected in a low long-run price elasticity of travel demand. Consequently, it takes substantial increases in the gasoline tax to make an impact on long-run travel demand. Simulation results show that under an alternative policy option, where EPA's standards are specified in terms of grams of pollutant per gallon of fuel burned, the same long-run reduction in exhaust emissions achievable today can be achieved (at an even higher level of confidence) with less than one-tenth of the increase in gasoline price required under the existing policy regime. 相似文献

This article explores the reasons for the introduction of anticorruption agencies of a specific type in Eastern Europe. It
is argued that one of the important functions of these agencies—which are stronger on information gathering, coordination
and strategy rather than on investigation of concrete cases—is to give to the government some leverage over the anticorruption
discourse. Presenting the anticorruption commissions and agencies as (discourse-controlling) instruments gives an answer to
the troubling question why governing parties are at all interested in the introduction of such bodies. Apart from instrumentalization in political discourse, anticorruption
bodies in Eastern Europe have had other effects as well. As shown in the Baltic case, institutional engineering provides for
a brief window of opportunity during which political forces committed to integrity could gain the upper hand. The problem
in Eastern Europe, however, is not the lack of such windows of opportunities—it is more the lack of really committed political
forces capable of continuous and consistent anticorruption effort. 相似文献

This paper discusses empirical findings and theories about prison higher education and recidivism. The research designs of
available evaluations of prison higher education are discussed. Their results in regard to arrest and return to prison after
release are presented in tables and figures. Both opportunity theory and moral development theory have been used to justify
such prison programs as crime prevention measures. A critical examination of the actual findings of the evaluations carried
out up to now suggests that prison higher education may have had only a slight impact on recidivism. One could, therefore,
doubt the value of opportunity theory and moral development theory to justify prison higher education as a crime control measure.
However, the methods used in the evaluations of this program have been generally weak. Thus, there is a continuing need to
carry out well-designed research on this question. The findings of follow-up studies of prison higher education have significance
for issues of correctional education policy as well as criminological theory. 相似文献

Teaching Students How to Use Emotions as They Negotiate 总被引:1,自引:0,他引:1

Given that emotions are inescapable and complex, how do you teach students how to deal with them? This article offers instuctors a practical approach. It suggests that instructors and students turn their attention away from emotions and toward a more limited set of core emotional concerns that stimulate many emotions. The article describes ways to teach students how to use these core concerns as tools to understand the emotional terrain and to stimulate helpful emotions. 相似文献

This article examines challenges for accountability arising from the development of the Schengen law within the framework of the European Union. Building upon the substantive body of research by other authors on general implications of the integration of the Schengen acquis , it focuses on recent developments after the entry into force of the Treaty of Amsterdam and evaluates to what extent the European institutions have so far met the challenges for accountability stemming from the intergovernmental origin of the Schengen law. The article identifies various persisting deficiencies in the areas of transparency, institutional balance and judicial review and proposes specific actions, which should be addressed vigorously by the European institutions. 相似文献
