De minimis and equity in risk

Indices and orderings are developed for evaluating alternative strategies in the management of risk. They reflect the goals of reducing individual and collective risks, of increasing equity, and of assigning priority to the reduction and to the equity of high risks. Individual risk is defined as the (random or non-random) level of exposure to a danger. In particular the role of a lower negligibility level is investigated. A class of indices is proposed which involves two parameters, a negligibility level and a parameter of inequality aversion, and several interpretations of the indices are discussed. We provide a set of eight axioms which are necessary and sufficient for this class of indices, and we present an approach to deal with partial information on the parameters.     

A fast splitting procedure for classification trees

This paper provides a faster method to find the best split at each node when using the CART methodology. The predictability index is proposed as a splitting rule for growing the same classification tree as CART does when using the Gini index of heterogeneity as an impurity measure. A theorem is introduced to show a new property of the index : the for a given predictor has a value not lower than the for any split generated by the predictor. This property is used to make a substantial saving in the time required to generate a classification tree. Three simulation studies are presented in order to show the computational gain in terms of both the number of splits analysed at each node and the CPU time. The proposed splitting algorithm can prove computational efficiency in real data sets as shown in an example.

中小学教师依法治教的困境与对策

中小学教师是依法治教的实践者、宣讲者、推动者,是推动依法治教的关键因素之一。但是,在中小学教师依法治教的过程中,还存在着中小学教师法治素养良莠不齐,教育立法滞后、执法不严、司法不公以及中小学教师职前、职后法治教育缺失等现象。全面推进依法治国,实现教育治理体系和治理能力现代化,必须深刻把握和充分发挥中小学教师在依法治教中的价值和作用,增强其依法治教的自觉性;必须深刻分析中小学教师在依法治教中面临的各种困境与原因,采取针对性措施,做到有的放矢,综合施策。

“网上追逃”研究

“网上追逃”不仅涉及刑事诉讼中的侦查、审查起诉中的犯罪嫌疑人、审判阶段的被告人,也涉及刑罚执行阶段的罪犯,而且涉及监察案件的被调查人,因而并不仅仅属于侦查措施或者侦查活动。“网上追逃”的根本目的在于强制在逃人员恢复法定状态。强制恢复法定状态的措施主要包括异地拘留逮捕的协助执行、先行拘留、无证抓捕,以及由此发生相应的讯问、羁押、押解等相关活动。“网上追逃”应当从适用规范及权利保护两个方面进行规范。     

政策工具视角的中国装配式建筑政策文本量化研究

为了更科学地进行政策分析和研究,评测已有装配式建筑政策体系完善与否,从政策工具的视角,将基本政策工具、装配式建筑驱动主体和产业价值链组合成一个三维研究框架.利用该框架,运用内容分析法对中国现有13份中央政府级装配式建筑政策文本中采用的政策工具进行计量和分析.得出环境型和供给型政策工具过溢,针对企业和科研机构的政策工具缺失,装配式建筑产业价值链维度的政策工具滞后于其价值实现环节等结论,并为完善装配式建筑政策体系提出建议.     

国家义务构造论的功能主义建构

国家义务是保障公民权利不可或缺的工具。确定国家义务内容主要诉诸基本权利功能、人权保障和规范主义3种路径。但以上路径过于强调国家义务内容的组成,从而带来理论层级设计混乱、语词选择不一、内部逻辑不明、理论功能不完善、整体性建构缺失等弊端。欲解决以上诸问题,层级化、递进式的国家义务构造理论为可行方案。其中,自由权向社会权的转向决定其实质内容,需求层次理论形塑内部层级结构,而融贯体系化和系统构造论则提供外部理论支持。功能主义系统论和内容理论的积淀最终建构了以尊重、保护和给付为基本要素的“二元三层次多位阶”的国家义务构造论。     

Personality profiles of factitious disorder imposed by mothers: A comparative analysis

Factitious Disorder Imposed by Another (FDIA) can be difficult to expeditiously identify. Understanding personality characteristics of FDIA perpetrators via psychological assessment may decrease the time between initial abuse and identification of FDIA. Personality characteristics of FDIA mother-perpetrators were examined through a comparative analysis of MMPI-2 profiles. It was predicted that mother-perpetrators would have significantly higher overall profile elevations on the MMPI-2 and elevations on specific clinical scales than a comparative control group. Results indicated that mother-perpetrators displayed significantly higher, elevations on the Psychasthenia (Pt) and Schizophrenia (Sc) scales and a trend toward significantly higher elevation on the Psychopathic Deviate (Pd) scale than the control group. These findings, along with the demographic information obtained, establish a preliminary foundation for understanding an overall profile of mother-perpetrators.
