基于主体不平等的跨国界河流水资源分配的破产博弈研究

基于破产理论和讨价还价博弈,构建水资源分配的破产博弈模型。借鉴国际水法,构建主体在水资源分配谈判中的议价能力评价指标体系,将议价能力运用到破产博弈模型中,突出主体在水资源分配中的不平等性,减少水资源分配量与贡献、需求量和对水资源依赖程度的非对称性;结合主体的谈判破裂点,根据主体满意度函数的联动函数寻找水资源分配的最优解,使分配能同时满足个体理性和集体理性,并对澜沧江-湄公河流域进行实例研究。     

儒家非理性教育理念对当代思想政治教育的启示

儒家非理性教育运用天人合一的思想理念,将人心对外物的自然反映融入到诗、礼、乐教育活动中,从而熏陶人的积极正面的情感,使人的意志和动机朝向符合道德的方向被激发,最终使人在现实生活中能自发自觉地表现出《论语》等儒家经典所要求的道德行为和品质.儒家非理性教育理念将人心、道德与治国三者完美结合,对当代思想政治教育贯彻立德树人理念有重要的启发作用.

Decomposition of the main effects and interaction term by using orthogonal polynomials in multiple non symmetrical correspondence analysis

The multiple non symmetric correspondence analysis (MNSCA) is a useful technique for analyzing a two-way contingency table. In more complex cases, the predictor variables are more than one. In this paper, the MNSCA, along with the decomposition of the Gray–Williams Tau index, in main effects and interaction term, is used to analyze a contingency table with two predictor categorical variables and an ordinal response variable. The Multiple-Tau index is a measure of association that contains both main effects and interaction term. The main effects represent the change in the response variables due to the change in the level/categories of the predictor variables, considering the effects of their addition, while the interaction effect represents the combined effect of predictor categorical variables on the ordinal response variable. Moreover, for ordinal scale variables, we propose a further decomposition in order to check the existence of power components by using Emerson's orthogonal polynomials.     

What influences the size of child maintenance payments? A register‐based study of maintenance payments in Finland

The aim of this study was to explore how particular economic and demographic factors contribute to the level of the child maintenance payment (CMP) paid by the non‐resident parent. For this study, we used 5‐year longitudinal panel data from years 2009 to 2013 consisting of over 80,000 non‐resident parents from the Finnish Tax Administration and The Finnish Population Register Centre. Results from regression models indicate that the single biggest factor affecting the size of CMPs is the number of dependent children. We found that the non‐resident parent's higher income is associated with higher CMPs and that non‐resident fathers pay on average larger CMPs than non‐resident mothers, even after accounting for differences in income. Unexpectedly, we found that the age of the dependent child did not predict changes in CMPs. This suggests that once formal CMP‐contracts are determined between the parents, they are seldom changed. Our results suggest that some degree of mandatory periodic review for maintenance contracts is worth considering.

Repelling the “Rutter”: Social Differentiation Among Rural Teenagers

This paper examines low‐income white rural teenagers' management of race and class‐based inequality. It analyzes how these teenagers constructed boundaries to distinguish themselves from outsiders, but also to distinguish themselves from the local abject category of “rutter.” The findings reveal hidden interconnections between race and class in interactional practice, and highlight local processes of differentiation through which actors attempt to deflect stigma and attain credibility. The paper discusses how interactional mechanisms such as “internal othering” and “stigma‐theory” bolster race and class credibility, but reproduce inequality.
