程度与精度的逻辑差粗糙集模型

基于程度与精度的逻辑差需求,提出了程度与精度的逻辑差粗糙集模型,并定义了粗糙集区域概念。通过变精度近似与程度近似的转化公式,得到了粗糙集区域的基本结构,提出了计算粗糙集区域的常规算法和结构算法,进行了算法分析与比较,探索并得到了模型在决策表中的应用方向。通过该模型拓展了程度粗糙集模型和经典粗糙集模型。

A fuzzy clustering approach to evaluate individual competencies from REFLEX data

We empirically illustrate how concepts and methods involved in a grade of membership (GoM) analysis can be used to sort individuals by competence. Our study relies on a data set compiled from the international survey on higher education graduates called REFLEX. We focus on the subset of data related to the perception of own competencies. It is first decomposed into fuzzy clusters that form a hierarchical fuzzy partition. Then, we calculate a scalar measure of competencies for each fuzzy cluster, and subsequently use the individual GoM scores to combine cluster-based competencies to position individuals on a scale from 0 to 1.

Does schooling protect sexual health? The association between three measures of education and STIs among adolescents in Malawi

While multiple studies have documented shifting educational gradients in HIV prevalence, less attention has been given to the effect of school participation and academic skills on infection during adolescence. Using the Malawi Schooling and Adolescent Study, a longitudinal survey that followed 2,649 young people aged 14–17 at baseline from 2007 to 2013, we estimate the effect of three education variables: school enrolment, grade attainment, and academic skills—numeracy and Chichewa literacy—on herpes simplex virus type 2 (HSV-2) and HIV incidence using interval-censored survival analysis. We find that grade attainment is significantly associated with lower rates of both HSV-2 and HIV among girls, and is negatively associated with HSV-2 but not HIV among boys. School enrolment and academic skills are not significantly associated with sexually transmitted infections (STIs) for boys or girls in our final models. Efforts to encourage school progression in high-prevalence settings in sub-Saharan Africa could well reduce, or at least postpone, acquisition of STIs.     

从价值定位看孔子文艺思想的当代意义

基于爱人基础上的仁学思想,是孔子对文艺价值定位的第一标准。"仁"、"美"、"善"三者相通,这是人道主义和艺术本体论相结合的最初表述,符合人类的根本利益。实践这一理论,既可优化文艺的生态环境,又可提升文艺作品的品位,并"生产完整的人",让人类诗意地栖居。     

论自然人民事行为能力制度之重构

民事行为能力制度是民法基础理论问题。我国现行自然人民事行为能力制度存在等级划分不合理;划分标准缺乏准确性;对行为能力欠缺者过于保护;相关配套制度不合理、不完善等诸多问题。针对于此,现行自然人民事行为能力制度应重新构建,应依照新的划分标准将其划分为完全民事行为能力与限制民事行为能力两个等级,建立并完善宣告、亲权和监护等相关制度。     

控制权市场经济影响因素的经验分析——以美国1970-1999年的市场为例

通过对影响控制权市场的三个主要经济因素的剖析,并结合美国1970-1999年控制权市场的数据,本文建立了控制权市场与宏观经济、资本市场以及法律政策等因素的可量化指标体系,运用灰色关联度模型,对各个影响因素的重要性进行了排序.研究的主要结论为:长期来看,影响兼并与收购交易金额的因素与影响交易数量因素的重要性排序是一致的,其首要因素是股票综合指数;影响两次浪潮中并购交易数量的首要因素均为新增直接投资.
