Inferring a linear ordering over a power set

An observer attempts to infer the unobserved ranking of two ideal objects, A and B, from observed rankings in which these objects are `accompanied' by `noise' components, C and D. In the first ranking, A is accompanied by C and B is accompanied by D, while in the second ranking, A is accompanied by D and B is accompanied by C. In both rankings, noisy-A is ranked above noisy-B. The observer infers that ideal-A is ranked above ideal-B. This commonly used inference rule is formalized for the case in which A,B,C,D are sets. Let X be a finite set and let be a linear ordering on 2^X. The following condition is imposed on . For every quadruple (A,B,C,D)Y, where Y is some domain in (2^X)⁴, if and , then . The implications and interpretation of this condition for various domains Y are discussed.     

社群主义权利观念解析

社群主义在批判自由主义权利理论过程中阐释了“善优先于权利”的观点。社群主义将观念与制度的共同体视为权利的基础,认为共同体的民主过程建立了权利的正当性,将权利的本质理解为一种“资格和义务之间制度化的关系”,从而带有权利道德化的倾向。     

第六次科技革命影响下的教育变革

科技革命历经数次,其所驱动下的教育活动发生了制度化、民主化、实用化等积极变化.时至今日,科技革命正以第六次形态悄然渗透于人类生境,并将颠覆性影响人类生活.面对新一轮科技革命,当今教育却难免在人才培养结构与高水平科技人才需求、学科建设与科技发展步伐、教学方法与科教变革潮流、思想品德教育与学生价值观形成、教师信息技术应用与未来教育发展、科教协同融合与科技发展趋势等方面遇到新的挑战.立足新的起点和第六次科技革命的未来影响,着眼重塑国力、助力科技创新和人民美好生活向往,未来教育也必将在教育环境和教育资源、教育内容和教育方式、教师身份和教育手段、教育评价和教育治理等方面发生重大变革.

Argumentation in Multi-issue Debates

An axiomatic modeling approach to multi-issue debates is proposed. A debate is viewed as a decision procedure consisting of two stages: (1) an “argumentation rule” determines what arguments are admissible for each party, given the “raw data”, depending on the issue or set of issues under discussion; (2) a “persuasion rule” determines the strength of the admissible arguments and selects the winning party. Persuasion rules are characterized for various alternative specifications of the argumentation rule. These characterizations capture rhetorical effects that we sometimes encounter in real-life multi-issue debates.
