对于语境中的词义变异现象,学界常冠以“不可捉摸”“变化无常”之名,但这貌似无常的背后,是否依然有章可循?本文基于动词与名词互为语境视角,通过考察动词的语义依赖和语义密度两大属性,揭示动词语境意义变异的规律性特征。研究发现有... 对于语境中的词义变异现象,学界常冠以“不可捉摸”“变化无常”之名,但这貌似无常的背后,是否依然有章可循?本文基于动词与名词互为语境视角,通过考察动词的语义依赖和语义密度两大属性,揭示动词语境意义变异的规律性特征。研究发现有三:一是词义共振原理是动词语境意义变异的机制和动力;二是动词语义因定义缺省,对名词具有依赖性,语境中的动词往往围绕名词进行意义构建,这种词义构建的变异模式体现出行星围绕太阳的类公转型特征;三是动词自身语义密度的高低与类公转型特征的显著性层级成反相关关系。 展开更多

基于形容词和名词互为语境视角,考察了具有不同语义属性的形容词语境意义变异的规律性特征。研究发现:交集形容词强调事物的客观性特征,语义相对清晰和明确,其语境意义构建的类公转型特征不显著;从属形容词强调人对事物的性质和状态的... 基于形容词和名词互为语境视角,考察了具有不同语义属性的形容词语境意义变异的规律性特征。研究发现:交集形容词强调事物的客观性特征,语义相对清晰和明确,其语境意义构建的类公转型特征不显著;从属形容词强调人对事物的性质和状态的主观评价,语义往往不清晰、不明确,其语境意义构建主要围绕名词不断调整,呈现出显豁的围绕名词公转的特征;交集形容词和从属形容词语境意义构建的认知心理本质都是基于心理情境的模拟过程。 展开更多

Income gaps in China kept widening over the past four decades of economic transition. First, this paper describes the change in income gaps before and after reform and opening-up in 1978 and found that income gaps had been expanding between urban and rural areas, within cities and within the countryside. However, this did not lead to income polarization since low-income groups only had a slower income growth compared with highincome groups. The number of poor people continuously reduced thanks to rapid economic growth. Over the past decade, the widening of income gaps has been initially curbed. Accordingly, we explained the impact of economic transition on income distribution from the perspectives of market-based distribution, ownership structure, opening-up and internal income distribution. Lastly, this paper provides an in-depth analysis on urban-rural income gaps, excessive compensation in monopolistic sectors and income inequalities arising from corruption. To address these problems, it is important to enhance tax regulation, increase transfer payments to poor people, improve social security, equalize public services, enhance poverty relief and develop a fairer income distribution system. 展开更多

Compared with the traditional offenses of embezzlement, bribe-taking and so on, the misappropriation of public funds is not a routine charge but a result of the response of criminal law to social transition. The fact that a number of difficulties have arisen in legislative and judicial procedures relating to this offense makes the value of case reference material significant. The Supreme People's Court of China attaches great importance to the publication of cases of misappropriation of public funds, which offer guidance and reference for real-life adjudication. Cases publicized in the last decade reflect a judicial emphasis-- they focus on the official nature of the duties performed by the subject, on understanding "for individual use" from the viewpoint of formal rationality and on a cautious interpretation of the connotations of "public funds." Publicizing such cases facilitates reaching the same verdict in similar cases and at the same time acts as a catalyst for the advancement of theory and practice. 展开更多
