Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year. 相似文献

作为大多数法学理论著述的一种范式 ,非概念性法学涵盖了十分丰富的内容 ,其目标 ,就是要陈述那些经得住反驳的、有知识旨趣的问题 ,以及法律及其后果的社会作用问题。所以 ,非概念性法学理论都是可证伪的。法学对话 (Legaldialogue)则为检测非概念性法学理论提供了至关重要的途径。因而所有的主张 (无论是明确的主张还是隐含的主张 )都是法学对话参与者试图表达其不同观点的手段 ,而他们所要表达的这些截然不同的观点 ,莫过于以下三大类 ,即 :事实、价值与行为 相似文献

This article examines how pensions are interwoven with the public and private financial system in Japan and the consequences for pension reform. A growing literature focuses on the multifaceted ways in which pensions are interwoven with the larger political economy. This study builds on this literature and finds that (a) public and private pensions have been integrated deeply into Japan's system of developmental finance, (b) this integration has created new economic and political problems as governments have attempted to shift away from its developmental model through deregulation, liberalization, and administrative reform, and (c) because pension reform is intimately linked with these reforms, it involves addressing fundamental issues regarding the role of the state, finance, and firms. These findings collectively illustrate that pension reform is not only driven by issues of fiscal viability and benefit levels, but also by the nature of the way in which pensions are integrated into a country's system of finance. 相似文献

To examine the infant health impact of prenatal exposure to power plant emissions, we draw scientific evidence on the impacted region downwind of a large polluter, a coal‐fired power plant located on the border of two states and proven to be the sole contributor to the violation of air quality standards of the impacted region. Our results show that among all live singleton births that occurred during 1990 through 2006, those born to mothers living as far as 20 to 30 miles away downwind from the power plant (which is also an affluent region) during pregnancy are at greater risks of low birth weight (LBW) and very low birth weight (VLBW): the likelihoods of LBW and VLBW could increase approximately by 6.50 and 17.12 percent, respectively. In light of the continual efforts of The U.S. Environmental Protection Agency in reducing cross‐state air pollution caused by transboundary power plant emissions, our study is aimed at broadening the scope of cross‐border pollution impact analysis by taking into account adverse infant health effects of upwind polluters, which can impose disproportionate burdens of health risks on downwind states due to air pollutants transported by wind. 相似文献

The association of pubertal maturation with internalizing and externalizing symptoms was examined with a sample of 867 African-American 10 – 12-year-old children. Children reported their pubertal development status and timing using a self-report questionnaire, and symptoms were assessed through diagnostic interviews with the children and their primary caregivers. Pubertal status and timing were significantly associated with children's reports of the internalizing symptoms of social anxiety disorder, generalized anxiety disorder, and major depression and with the externalizing symptoms of oppositional defiant disorder, attention deficit disorder, and conduct disorder. Pubertal development also was associated with caregivers’ reports of children's externalizing symptoms. The pubertal transition was associated with internalizing and externalizing symptoms in both boys and girls.Xiaojia Ge is Professor at the University of California, Davis. He received his PhD in sociology from the Iowa State University. He is interested in the influences of biological changes and social transitions on emotional and behavioral development in children and adolescents.Gene H. Brody is a Regents’ Professor at the University of Georgia. He received his PhD in developmental psychology from the University of Arizona. His major research interests are contextual influences on cognitive and psychosocial development, particularly those factors that protect at-risk children and adolescents from negative outcomes.Rand. D. Conger is Professor at the University of California, Davis. He received his PhD in sociology from the University of Washington in Seattle. He is interested in the influences of family economic stress on emotional and behavioral adjustment of family members. He is currently conducting a large-scale study on Mexican American families in California.Dr. Ronald L. Simons is Distinguished Research Professor at the University of Georgia. He received his PhD in sociology from Florida State University. Much of his research has focused upon the manner in which family and community processes combine to influence child development. He has also been concerned with the effect of discrimination and racial socialization upon child adjustment. 相似文献
