Liberty,equality, and impossibility: some general results in the space of ‘soft’ preferences

This paper is concerned with examining the mutual compatibility of the ethical principles of equity and liberty in a social choice framework of ordinally formulated vague preferences. With sufficiently weakened versions of the liberty and equity principles, one can secure an existence result in a ‘relation‐functional’ setting. However, difficulties tend to re‐appear in a ‘choice‐functional’ setting, when one subscribes to the notion that while preference may be vague, choice must perforce be exact.     

刍议“极简主义”景观设计的生态学意义

"极简主义"景观在形式上追求极度简化、客观、抽象,在设计过程中引入生态规划的理念,遵循"最少干预"生态设计原则,以最少的元素、景物,保护了生态环境,实现了人与自然的和谐统一。本文从设计观念、材料、视觉、经济、空间秩序几个方面分析了极简主义景观设计的生态学意义。     

健全我国农村最低生活保障制度的基本思路

当前,我国农村最低生活保障制度建设已全面展开,但由于传统认识偏差、财政投入匮乏、制度建设滞后等原因,导致农村最低生活保障实践中出现了“一大”、“二低”、“三难”等问题。因此,转变传统观念、加大财政投入、加快制度建设是完善我国农村最低生活保障制度的必备因素。     

规模养殖企业环境行为反馈机理分析

当前随着我国养殖企业的迅速发展和养殖企业规模化不断提高。规模养殖产生的污染量量迅速增加且相对集中，导致环境污染问题日益突出。对规模养殖企业环境污染问题进行了研究，首先运用流率基本入树建模法，建立规模养殖企业环境行为系统的动力学模型，然后运用极小反馈基模生成法逐阶求出极小反馈基模，最后在极小反馈基模的基础上，构建具有实际意义的增长上限反馈基模，并提出具有现实意义的增强企业环境行为的建议。     

Refining the Lorenz-ranking of rules for claims problems on restricted domains

The comparison of the central rules for claims problems, according to the Lorenz order, has been studied not only on the entire set of problems but also on some restricted domains. We provide new characterizations of the adjusted proportional rule as being Lorenz-maximal or Lorenz-minimal within a class of rules on the half-domains. Using this result, we rank the adjusted proportional, the minimal overlap, and the average-of-awards rules by analyzing whether or not these rules satisfy progressivity and regressivity on the half-domains. We also find that the adjusted proportional rule violates two well-known claim monotonicity properties.
