A comparison of the Korean minorities in China and Japan

"This article compares the Korean minorities in China and Japan in their differential levels of cultural autonomy and ethnic identity....In explaining the differential levels of ethnicity between the two Korean minority groups, this paper focuses on the basic differences in minority policy between the two countries; the difference in the context of migration; the existence or absence of a territorial base; and the differential levels of influence from Korea."     

"创造的教育"高校课堂教学质量评价工具开发及应用研究

“创造的教育”理念,既是对党和国家创新驱动发展重大战略的积极响应,也彰显着新时代高校人才培养的目标和特色。师范大学秉持“创造的教育”理念具有重要意义,指引着高校教学模式改革的方向。如何基于“创造的教育”理念评价高校课堂教学质量,是急需解决的重要问题。本研究通过项目分析、探索性因素分析,开发了“创造的教育”高校课堂教学质量评价工具,得到了两个主要因素,分别是“内容驾驭”(教什么)和“策略运用”(怎么教)。通过聚类分析和判别分析,将“创造的教育”高校课堂教学表现的水平划分为低水平、中水平、高水平三个等级,建议高校教师及其课堂教学：基于学科理解提升教师内容驾驭能力,注重学科思维方式和方法显性化呈现,加强基于远迁移问题解决的任务设计,优化课堂教学中挑战性问题的设置,注重课堂教学体现学生中心的理念。     

Axiomatizations of the normalized Banzhaf value and the Shapley value

A cooperative game with transferable utilities– or simply a TU-game – describes a situation in which players can obtain certain payoffs by cooperation. A solution concept for these games is a function which assigns to every such a game a distribution of payoffs over the players in the game. Famous solution concepts for TU-games are the Shapley value and the Banzhaf value. Both solution concepts have been axiomatized in various ways. An important difference between these two solution concepts is the fact that the Shapley value always distributes the payoff that can be obtained by the `grand coalition' consisting of all players cooperating together while the Banzhaf value does not satisfy this property, i.e., the Banzhaf value is not efficient. In this paper we consider the normalized Banzhaf value which distributes the payoff that can be obtained by the `grand coalition' proportional to the Banzhaf values of the players. This value does not satisfy certain axioms underlying the Banzhaf value. In this paper we introduce some new axioms that characterize the normalized Banzhaf value. We also provide an axiomatization of the Shapley value using similar axioms. Received: 10 April 1996 / Accepted: 2 June 1997

经济发展视域下的社会稳定关联因素分析

经济发展视域下的经济增长、就业、收入差距、社会保障、弱势群体等因素与社会稳定之间存在复杂和多面的关联.这种关联的复杂性和多面性既取决于这些因素本身,也取决于和这些因素及社会稳定相关的许多其他变量.基于关联视角的社会稳定对策要注重强化经济发展中相关方面与社会稳定的正相关,弱化相关方面与社会稳定的负相关,将正相关发挥到最大限度,把负相关减弱到最低程度.     

"了"、"却"的语法化以及"了"、"却"的替换

汉语词汇很早就出现实词和虚词的区分。虚词大都是通过实词转变而来,通常是由于某个实词或因句法位置或者组合功能的变化而造成词义演变,或因词义的变化而引起句法位置、组合功能的改变,最终使之失去原来的意义。本文对"却"、"了"两个虚词的语法化作了一个较为详细的描写,并从历时的角度对其演变作出解释。
