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

婚约法律问题研究   总被引:6,自引:0,他引:6  
熊进光 《河北法学》2003,21(6):54-59
婚约是婚姻关系建立前的习惯性程序,经历了从罗马法、寺院法到近现代法的不同发展时期,产生的法律效力也各有不同。婚约在我国是一种重要的民事习惯,历代封建统治者都十分重视对婚约关系的调整。婚约的成立应以当事人自愿自行订立、具有完全民事行为能力、未婚及无禁止结婚的血亲关系为条件,依法成立的婚约对双方当事人及第三人均产生一定的法律效力。婚约存续期间双方互赠的财物,在婚约解除时应按不当得利予以返还。一方擅自解除婚约或因他方过错而解除婚约的,无过错方可请求损害赔偿。将婚约视为纯粹的道德问题,不仅人为地缩小了民法的调整范围,也不利于财产纠纷的解决,应通过民法典的制定予以规范。  相似文献

More than a decade after NAFTA (North American Free Trade Agreement) entered into force, the environmental effects of agricultural trade liberalization in Mexico are still controversial, emerging, and not fully understood. This paper contributes to the literature that aims to explore trends in input use in the agricultural sector in Mexico during the post-NAFTA period among both commercial/industrial and traditional/rainfed farmers, and examines the influence of the national and multilateral institutional framework on these outcomes. We decompose the post-NAFTA agricultural production data into scale, technique and composition effects to estimate the impact that trade liberalization has had on the use of fertilizer and land use, two key agricultural inputs for which reliable aggregate data is available. We conclude that among commercial farmers patterns of crop type specialization and significant technological improvements have led to some declines in fertilizer use but they have been offset by growth in fertilizer use associated with growing agricultural output. Among traditional farmers increased output and specialization in land-intensive grain crops are contributing to an increase in land under cultivation and technological improvements show the potential, but not yet not the strength, to counteract these effects. We analyse the environmental institutional framework and rural development plans, observing that institutional weaknesses have, in several instances, reduced the environmental benefit of technique and composition effects. We conclude with recommendations about how the Mexican agricultural sector might reap the environmental benefits of international agricultural trade.  相似文献

3、压力的行为反应机制应对压力,不仅是心理反应的认知与方式、方法,生理反应的生化过程,更是在特定环境中的行为适应过程。人的本质,体现为“社会关系的总和”(马克思)。因此,行为适应是一个人健康特别是心理健康与否的重要标志。医学心理学把“心理障碍”界定为:“没有能力按照社会认为适宜的方式行为,以至其行为后果对本人或社会是不适应的。”“没有能力”,可理解分为器质性的损害和功能性的损害,也可能是两者兼而有之。生理、心理反应是内在的,行为反应是外显的。在现实生活中,当人们出现心理问题时,尽管通过主观意志努力可以在行…  相似文献

There has been a recent resurgence of interest in the electoral impact of constituency campaigns in British General Elections. Much is now known about the electoral consequences of local campaigns on parties’ constituency vote shares. Yet more remains to be discovered about the impacts of these local campaigns on voters’ knowledge of parties and candidates. Analysis of data from the 1997 British General Election demonstrates that the local campaign is associated with improved voter knowledge of who is standing for each party in a constituency, which is, in its turn, associated with an increased chance of voting for the party in the election, other things being equal. Campaign efforts at different scales, from the national to the local, have different impacts on voters’ knowledge.  相似文献

苏联解体后其庞大的核武库也一分为四,在核武器系统、核材料、核科学家及核技术等三个层次都出现了失控的核扩散危机。以美国为首的国际社会从各个方面给予了大力援助,使前苏联庞大的"核遗产"得到了妥善的处理。因苏联解体而一度出现的核国家增多的问题得以解决,核扩散危机也基本得到消除。这不仅有效地捍卫了国际核不扩散体制,而且在实践上也是对国际核不扩散机制的补充和发展,对人类社会的和平与安全也是重大的贡献。当朝鲜和伊朗核问题屡成危机而长期困扰国际社会时,我们重温这段历史,也具有深刻的现实意义。  相似文献

保险领域中,公共政策要求“一个人不能从自己的犯罪中获利”,但须区分“一个人不能从他人的犯罪中获利”之情形。被保险人故意犯罪致保险事故发生,应视保险目的与功能而异其法律后果:若被保险人因预谋犯罪而直接谋求保险金,保险人当然免责;若被保险人在投保二年后故意犯罪致保险事故发生,则保险人虽不负给付保险金之责,但应退还保险单的现金价值;若故意犯罪并非保险事故发生的直接原因,保险人不能当然免责。  相似文献

Despite renewed interests in the labeling perspective and the impact of official intervention on individuals’ future outcomes, scant attention has been given to potential conditioning factors for theorized labeling processes. We argue that, when viewed through a symbolic interactionist lens, variations in the nature of primary social groups, through which individuals filter official labels like arrest, may generate patterns for subsequent self-concept and delinquency that are contrary to what labeling theory indicates. To test our rationale, we offer a moderated mediation model in which gang membership is expected to differentially impact the effect of arrest on future delinquency through an intermediary mechanism: self-esteem. We test a gang–nongang dichotomy and then probe further to test whether hypothesized effects are gang specific or occur similarly for nongang youths with highly delinquent peer groups. Analyzed using Rochester Youth Development Study (RYDS) data (N = 961), comparisons between gang members and nonaffiliated youths with similarly highly delinquent peer groups revealed no significant differences in conditional indirect effects of arrest on self-esteem and future delinquency; the two groups were similarly insulated from any negative impact of arrest on self-esteem. For nongang youths with fewer delinquent peers, however, arrest significantly reduced later self-esteem, which in turn increased their future delinquency.  相似文献
