历史不一定是发展史———中国古代都城形态史的解构

以往的研究认为中国古代都城城市形态的历史是一种前后相继的发展史，使用的主要研究方法就是对城市形态进行相似性比较，但这种方法在逻辑上存在根本性的问题，因此其结论是值得质疑的。基于对这一问题的研究，我们可以进一步认为，历史并不一定就是事物、事件之间有着密切联系、存在发展阶段以及变化规律可循的“发展史”，而可能只是由一些不存在密切联系，只是在时间上具有先后顺序的同类对象构成的历史。

工程质量政府监督多层次利益分配与激励协同机制探究

The implementation of the government supervision of the quality of the project is an international practice. The basic form of government supervision of engineering quality is government supervision on the quality behavior of the engineering main bodies and its results by the competent government department entrusted. Its essence is a dual principal-agent process. The frequent accidents of the engineering quality reflect the loss and failure of the government law enforcement supervision of the engineering quality to some extent. Its root lies in the lack of endogenous power in the law enforcement supervision of the project quality government supervisors in the law enforcement supervision. Therefore, the incentive coordination mechanism of the government supervision based on the multi-level interest distribution is worth explored. In views of the multi-level management system which is formed by the government departments, government quality supervision organizations, quality supervision team (or group) for the government supervision of engineering quality. The benefit distribution function between every party is constructed, and the game model of the multi-level incentive and coordination for the government supervision in engineering quality is built. To solve and deduce from the first stage of the cooperative game and the second stage of the non-cooperative game, the cooperative game can obtain the reward coefficient: . The coordination degree of the best effort can be obtained by the non cooperative game. The result shows that:the coordination degree of government engineering quality supervisor is related to the coordination costs, and had nothing to do with fixed costs. The benefit distribution coefficient not only depends on the efforts of the quality government monitors, but also on the efficiency of other parties' efforts. The quality supervisors of the project will also focus on the coordination with other parties when enhancing their management capabilities to improve the overall performance of project quality government supervision. The strategy of the incentive coordination mechanism for the supervision and cooperation of the project quality government is:the government quality supervision team should set up the supervisory team properly, improve the coordination efficiency and reduce the cost of supervision-coordination to maximize the value of self-motivation. Quality supervision team (or group) should establish the partnership to improve the coordination efficiency for achieving the maximization of their own incentive value.The model and conclusion of incentive synergy mechanism based on multi-level benefit allocation mechanism are researched. It can provide theoretical support and practice reference for the market governance and supervision of general public goods.     

现代技术与货币经济视野下的家庭处境

从现代技术与货币经济这两个内在关联的主题探讨家庭危机之根源所在。现代高科技渗透现实生活领域,瓦解了身体、家庭和宇宙四位一体、相互感通的整体性,导致家庭存在的意义丧失。货币作为是现代生活中"最普遍的技术",其对人的内在世界,包括个人的生命力、个体命运与整个文化的影响,深刻地表现在其对婚姻家庭观念的重新塑造上。在货币经济时代,金钱化、物欲化,以及极端个人主义,抑制了琴瑟和鸣的人间情感,滋生出异化的现代"金钱婚姻"观念,演变出比前现代更深刻的"文化悲剧"。尽管家庭处境堪忧,但不能因此就否认家是人生命之根基的事实。返家归本构成人生乃至人类文明永恒的主题。     

英格兰数理精英教师培养及启示——基于“未来教学学者”计划

英格兰政府针对国内中小学数学和物理等学科专业教师紧缺、学生数理成绩较差的现状，推出了"未来教学学者"（Future Teaching Scholars）精英教师培养计划。这一专项教师培养计划旨在通过严格的选拔标准、系统的培养方案、丰厚的奖学金与助学金以及明确的教师未来职业发展规划，吸引高质量的本科生积极参与，从而提高英格兰数理学科教师的专业水平及学生的数理学科成绩。英格兰政府为改善特定科目和偏远地区学校教师质量而开展的专项教师培养项目为我国相关教师的培养工作提供了积极借鉴：创新教师教育培养模式，提高师范生教学实践能力；充分发挥地方师范院校的主体作用，保障特定地区教师供应；提高师范生选拔标准，促进教师队伍整体质量提升。     

加嬭编钟与楚庄王服曾

新出春秋铜器加嬭编钟是曾侯夫人加嬭的自作用器,但铭文中自称"文王之孙子,穆之元子"之人并非曾侯,而是楚庄王熊侣.器主加嬭即随仲嬭加鼎中楚王所嫁之女随仲嬭加,她依靠楚国的支持在丈夫曾侯宝去世后代执国政.编钟铭文所记是楚庄王巡省已归附楚国的曾国,加嬭代表曾国燕享楚王之事.从加嬭在楚庄王面前自称"孺小子"来看,其人应即庄王之女.如此一来,加嬭媵器随仲嬭加鼎的作器者也宜定为楚庄王.     

比较优势动态递减概率模型及检验

在比较优势的持续时间是随机变量的条件下,文章运用不确定性数学方法和规范方法,推出了比较优势递减定理,认为比较优势会随着时间增加而递减,具有发散效应,即比较优势不会被锁定.推出的比较优势“无记忆性”定理表明,各国遵循比较优势发展国际贸易是正确的,国际贸易会让各个国家自动寻找到适合本国的比较优势.通过定义比较优势逆转概率,运用实证方法进行研究,研究表明比较优势基本符合比较优势递减定理和“无记忆性”定理内容,认为中国传统劳动密集型优势在逐渐减小,产业结构调整非常成功,逐渐拥有资本密集型优势和技术密集型优势,产业结构越来越合理.     

Overcoming Uncertainty: Agency,Stance, and the Rise of Collective Action in Times of Crisis

This article examines how grassroots actors initiate and engage in collective action to transcend dramatic situations of large-scale societal crisis. Merging strands of sociolinguistic scholarship with social movement theory, the concepts of stance and stance-taking are presented to reveal how individuals collectively exert their agency during episodes of macrostructural instability and uncertainty. Stance is defined as the agentive and solidaristic position taken up by a group of actors to navigate and overcome moments of social rupture. Stance-taking is the situational ensemble of discursive, organizational, and dramaturgical practice through which stances are developed and deployed. Analysis of the social construction of stance promotes multidimensional understandings of how social movements intensify and expand under conditions of crisis. To illustrate the analytical purchase of these concepts, the study describes the stance-taking practices that fueled the rise of mass public protests in Buenos Aires, Argentina, at the height of a national crisis in 2001.     

Dimension reduction via local rank regression

Outer product of gradients (OPG) achieves dimension reduction via estimating the gradients of the regression function. In this paper, we propose two novel OPG estimators via local rank regression: the rank OPG estimator and the Walsh-average OPG estimator. Both proposals guard against a wide range of error distributions, and are safe alternatives to existing OPG estimators based on local linear regression or local L1 regression. The effectiveness of the new proposals are demonstrated via extensive numerical studies.
