A Study of Social Justice

我们的研究目标有三个：1)通过数学模型对社会公平进行理论反思，2)对关于正义感知的跨文化调查数据进行量化分析，3)将研究结果应用于社会问题。1)首先，我们建议引入一系列关于公平考虑的假设。个体之间的效用比较和独立性就是它们的例子。2)对发达资本主义国家和后共产主义国家的跨文化调查数据进行了分析。结果表明，在“发达资本主义国家”中，日本并不是正义观念的特殊国家。由于概观和具体的“微不足道”的差异对于跨文化理解都很重要，我们试图找出两者。3)首先，我们坚持认为，在最近的日本，不仅分配正义而且程序正义变得更加重要。其次，在国际交流中，关键是要使各国的正义理念既有相同之处，也有不同之处。

Our targets of study were threefold : 1) theoretical reconsideration on social justice through mathematical modeles, 2) quantitative analysis of cross-cultural survery data on perception of justice, 3) application of research results to social problems.1) First, we suggested to introduce couples of hypotheses for justice considerations. Utility comparison and independence between individuals are examples of them. Second, we proposed a use of neural-network models for the analysis of perception of justice to analyze non-linear relationships.2) We analyzed cross-cultural survey data on "advanced capitalism countries" and "post-communist countries". The results showed that Japan is not a special country among "advanced capitalism countries "in terms of perceptions of justice. Since both overview and concrete "trivial" differences are important for cross-cultural understanding, we tried to find out both.3) First, we insisted that not only distributive justice but also procedural justice is getting more crucial in recent Japan. Second, it is critical to make the similarity and difference of the concept of justice among countries for international communication.
