关于汉字结构中字核的研究

通过对两组汉字的研究,发现汉字的结构中存在一个核心———字核,它具有简化汉字结构、沟通若干汉字的桥梁作用。据此,笔者提出在汉字的结构中普遍存在字核的假设,再依此假设对《辞海》的全部汉字(14872个)进行了系统研究。研究发现其中的14582个汉字的结构中存在字核,占被研究汉字总数的98%以上。全部汉字中共有字核900余个,列于字核总表中。结果表明:字核在汉字结构中客观而普遍的存在,它具有简化汉字结构、沟通同一字核的若干汉字联系的桥梁作用。     

多源模型的新进展

公共物品的提供模式及政府管制的效率比较

随着技术水平以及人们收入水平的不断提高,市场力量不断进入到公共物品的提供领域,然而由于公共物品对于社会公平、公正带来的重要影响,政府会对市场提供公共物品时进行有效管制,而最主要的管制模式就是进行价格管理。文章利用Wickstro¨m(2001)的模型,分析了政府在对市场提供公共物品进行管制时的效率问题,指出在成本信息不对称时政府管制的效率可能很低,反而给社会福利造成了比较大的损失,同时企业利润也受到影响。     

国防产业进入管制的经济学分析

实现对国防产业的有效管制,必须解决竞争规则与竞争程序不平等的问题,尽快建立管制规则和与之相应配套的法律法规。其意义在于通过引入非公经济,为国防产业发展提供一个有效的竞争平台和机制;民营经济的引入可以在节约公共财政开支的同时为国防开支增加资金来源。     

WTO下的美国和欧洲反倾销法及我国的对策

世界贸易组织 (WTO)反倾销守则最终将世界范围内的反倾销立法与实践统一起来。然而 ,作为反倾销措施适用最多的美国与欧共体 ,其国内立法和具体司法实践仍有很大不同 ,加上新的反倾销守则在诸如反规避措施的规定上未达成一致意见。因此 ,在今后相当长的时期内 ,反倾销守则将与各国国内立法与实践并存 ,这在反倾销措施日益成为贸易保护主义者首选手段的国际经济环境中显得更为重要     

Community-based household waste management: Lessons learnt from EXNORA's ‘zero waste management’ scheme in two South Indian cities

This paper presents two case studies on the efforts by a community-based organisation to promote a sustainable integrated waste management system in Indian mega cities. This effort was initiated in 1989 by a local non-governmental organisation (NGO) called EXNORA and is based on a ‘zero waste management scheme’ set up, run and financed by the residents themselves. As this model has been widely quoted as successful, the study aims at learning from two communities implementing this model.Results are reported from a survey of the two schemes that used various tools to assess both their performance and sustainability in selected residential areas of two Indian cities, Chennai and Hyderabad. The results indicate limited success of the schemes both in saving a significant fraction of the generated waste from dumping, and in rehabilitating the local poor. However, they show that motivated individuals can successfully set up and manage waste collection systems that lead to overall environmental improvements. The differences in the two schemes reflect how the local assets and contexts impact on the success of the scheme. The scheme in a rich neighbourhood of Hyderabad was less ambitious in its overall objectives and focussed on the provision of a waste management service, using the opportunity to provide local employment to a socially deprived fraction of the population. The scheme in a middle-class area of Chennai, although pioneering in its approach, suffered from diseconomies of scale and lack of social integration, making it less viable in the medium to long term. Both schemes suffered from a lack of community involvement, motivation and political support, which threatens the long-term sustainability of the enterprise. The research concludes that the role that communities can realistically play in management of their own waste depends on the local context. The system advocated by EXNORA seems to require significant local resources, and political and technical support which are hard to find and sustain without strong local leaders. Another model set up in the city of Visakhapatnam is finally introduced as an alternative. This is based on triangular contracts between the municipality, the residents and micro-enterprises and may provide a good solution in dealing with the technical and commercial aspects which communities find difficult.     

论清律对明律的继承和发展

《大清律例》作为中国古代最后一部封建法典,无论从制定过程、体例结构和内容等方面均继承了《大明律》,并有所发展;尤其是在继承明律的基础上,根据当时社会形势的发展变化随时进行损益,对维护清朝两百多年的封建统治起了重要作用。清律对明律成功的继承和发展,对今天继承传统法律、移植西方法律、完善社会主义法律、建设社会主义法治国家,无疑具有重要的现实借鉴意义。

论现代企业品牌管理

美国经济的衰退和全球高新技术市场的增长滞缓 ,给寻求跨地域发展的企业投下了重重的阴影 ,以往成功的经验已不足以借鉴。中国企业目前所具有的竞争力只能保持 3- 5年的时间。加入WTO后 ,中国企业品牌的寿命周期将会大大缩短。面对国际、国内环境的巨大变化 ,企业品牌的核心竞争力必须进行重新评价和创意。
