试论教育法地位的独立性

本文主要分析教育法是一个独立的部门法的原因。从划分部门法的标准来看,部门法的划分应由调整对象的社会功能来决定。教育法律关系的基本特征是社会性或公共性,它体现了作为独立的部门法的要求。教育法律关系已不能被简单地归结为是一种行政法律关系,现代教育发展的趋势也加强了教育法的公共性特征。     

论知识产权的法律适用

知识产权的法律适用包括统一实体法的适用和国内冲突法的适用两个层面,前者与加强和促进知识产权的国际保护及其统一化进程的国际趋势相适应;后者与知识产权关系所蕴涵的相关国家的价值取向和政策导向相适应,两者互为补充,相得益彰,舍其一则不能使知识产权的国际协调充分到位。     

中国共产党在西安事变中的独立自主立场

独立自主原则是中国共产党人依靠自己的力量 ,在长期的革命和建设中逐步形成的基本原则。中国共产党人坚持独立自主的原则 ,在遵义会议上第一次自己起来解决党内存在的问题和中国革命问题。西安事变的和平解决 ,则是中国共产党自己解决中国革命问题原则的集中体现 ,是爱国主义和无产阶级国际主义的高度统一。今天 ,我们建设有中国特色的社会主义 ,更要坚持走自己的路     

Why youth leave care: Understandings of adulthood and transition successes and challenges among youth aging out of child welfare

Child welfare policies and practices are changing to allow more youth to remain in care beyond age 18. Yet, the majority of youth do not stay. Given recent evidence suggesting that remaining in care may be beneficial, there is a need to understand why youth leave. Using data gathered from in-depth interviews with young people aging out of care, this paper explores this question, relating it to youths' understandings of adulthood and the successes and challenges they face during their transitions. We find that youth leave care because of misunderstanding and misinformation about the requirements for remaining in care, as well as because of a desire for autonomy and independence. Specifically, many youth equated adulthood with independence, and thus felt that they needed to leave care to achieve adulthood. Unfortunately, these efforts to be independent often hinder youths' development of supportive relationships, which they reported to be one of the greatest challenges in their transitions. Based on these findings, we conclude by challenging the conflation of adulthood and independence, as well as of childhood and dependence, calling for connected autonomy as a goal for child welfare involved young people of all ages.     

衍生企业组织演化:驱动与约束的权衡——来自企业纵向事件抽取与趋势分析

主辅分离是深化国有企业改革的需要,但大部分企业还处在分而不离的状态。如何让这些衍生企业独立发展、自主创新并获得良好绩效成为该政策的关键。衍生企业组织演化过程被划分为两个维度,即价值创造驱动和独立性约束。本文深入考察了一个国有企业的衍生企业发展历程,深度跟踪和提取了其七年的事件数据,通过纵向研究和扎根理论试图来填补理论缺口。通过实地调查、访谈与档案的抽取和印证数据,分类绘出事件的时间线索趋势图;通过纵向动态的相互趋势的不断比较,得到价值创造驱动和独立性约束分别与外部关系探索、亲缘关联关系和自主性投入一致性关系。研究主要的理论贡献在于把创业衍生企业的理论延伸到主辅分离这一具体政策导向措施的作用机理中,并得到其理论模型与核心权衡过程。     

演化经济学方法论述评

演化经济学方法论采用个体群思维方法研究经济问题,以达尔文主义作为哲学基础,借鉴批判实在论,强调回溯法。这使得其理论体系具有侧重于哲学思辨性而缺乏实证检验性,侧重于解释而缺乏明确的预测性的特点。个体群思维方法使得演化理论具有较强的应用性和较广的可拓展领域。达尔文主义体现了唯物论的哲学思想,更具现实性。演化经济学方法论是构建和保护演化理论的基本指导原则,也导致了它与主流经济学的强烈分歧,从而使得演化经济学处于边缘化和异端的地位。演化经济学的基本假设和具体方法为我们提供了新的研究思路和技术工具。     

Robustness measures for Bayes linear analyses

We consider the role of global robustness measures in Bayes linear analysis. We suggest two such measures, one for expectation comparisons and one for variance comparisons. Geometric interpretations of the measures are presented. The approach is illustrated by considering the robustness of certain multiplicative models to assumptions of independence, with particular application to a problem arising in an asset management model for water resources.
