中国城市经济的制度安排与绩效

从中国城市经济的制度安排与绩效的角度对中国经济进行思考是一个解读中国区域经济发展的重要视角。这种思考可分为计划经济体制和社会主义市场经济两个时期。在不同经济发展时期 ,政府对城市的设立或布局政策差别很大。这与制度安排的选择和政府行为的定位有关。政府积累城市布局经验和教训的过程 ,也是学会管理城市和建设城市、掌握城市经济发展规律的过程。领导人的认识和政府政策的改变 ,决定了中心城市集聚和辐射作用的发挥 ,影响着区域经济的发展     

马克思的生态劳动实践观及其现实价值

马克思科学地揭示了劳动实践的生态内涵,即劳动实践的生态本质、生态尺度及生态功用。从这个层面看,马克思的劳动实践观就是生态劳动实践观。认真解读马克思的这一重要思想,对于我们今天构建生态化的生产方式和生态型社会规范仍具有重要的现实意义。     

孙中山“权能分别学理”的形成及其基本内涵初探

孙中山“权能分别学理”是国际国内矛盾冲突和孙中山本人文化素养相结合的产物 ,是为解决本国政治权威危机 ,创建驾驭欧美之上的新型良善政制而创造出来的。该学理是孙中山宪法思想的核心与基石 ,其基本内涵包括 :权能分治、人民有权、政府万能、以权驭能和九权平衡四项原则 ,全方位体现了中西政治文化共同尊崇的宪法基本精神———和谐。

Child protection under Swedish law—legal duality and uncertainty

Society's responsibility to protect children from harm as prescribed by the UN Convention on the Rights of the Child raises complex questions about the fundamental rights of both children and parents, as well as when and how authorities are to intervene in order to protect children from maltreatment. Many child protection systems around the world attract considerable criticism, due in part to how the law responds to child protection matters. This article examines the Swedish child protection system from a critical legal perspective with the ideas conveyed within Therapeutic Jurisprudence as a theoretical starting point. The aim is to describe and analyze the legal challenges and dilemmas that meet this system. A legal ambiguity about when and how responsible authorities are to intervene, leading to significant uncertainty for both children and parents, is identified. Furthermore, the strong focus by Swedish authorities on voluntary measures to resolve child protection matters can lead to vulnerable children not receiving the protection to which they are entitled. Certain of the challenges and dilemmas described here are specific to the Swedish system due to its legal context and family support approach. However, other aspects resonate across legal systems and, therefore, may be of a more general interest.     

内生性随机前沿模型估计方法研究：无需工具变量的Copula方法

内生性是常见的计量问题，忽略内生性会导致估计量有偏且不一致。现有部分文献研究了内生性随机前沿模型的估计，但实现的前提是能够为内生性自变量寻找到合适的工具变量，而实际情况下合适的工具变量通常不容易获取。本文研究了在难以找到合适的工具变量的情况下内生性随机前沿模型的估计问题：结合Copula方法和极大模拟似然方法估计参数。此外，本文还构造了技术无效率的新的点估计，该点估计额外利用了内生自变量的信息，通常比JLMS法对应的点估计更有效。数值模拟表明，相比于已有研究，本文提出的方法估计精度更高。     

论农民养老中的政府职能

在现行农民养老体系中,政府尽管做了大量工作,但总体支持力度不够,影响了农村老年保障制度的正常发展。政府应明确和确立其主体地位,充分发挥自身职能,以促进农民养老问题的解决和农村老年保障制度的健康发展。     

The situated self and the negotiation of a “bad” identity in therapeutic foster care

This article presents one of the three main findings from twenty-three observations over four months. The study critically analyzed the naturally occurring discourse used in two foster homes between caregiver and youth to negotiate the self. Three main discourse genres included, “you're bad,” “boys to men,” and “learn the hard way.” This article focuses on the “you're bad” genre and the linguistic tools used to impose and refute the “bad” identity. The findings elicit theoretical considerations, such as addressing aspects of selfhood (e.g., behavioral demonstrations) apart from the naturally occurring day-to-day context within which the self developed (e.g., the pre-placement living environment). It is recommended that future discourse analytic research examines the ongoing development of self upon the return to the pre-placement living environment or other permanent environment.
