社会管理创新的系统模式构建研究

社会管理创新对我国和谐社会创建具有重大的理论与实践意义.通过回顾我国社会管理发展的历程、现状、存在的问题以及创新社会管理所面临的挑战,总结出社会管理创新的核心是构建起一套科学且具有可行性的管理系统模式.文章在已有的社会管理理论基础上,提出了社会管理创新的“12345N系统模式”以及在此系统模式的基础上加强和创新社会管理的对策建议.     

“甲型H1N1”流感防控中的公共卫生伦理难题

今年3月全球暴发“甲型H1N1”流感疫情,我国政府高度重视“甲型H1N1”流感的应对工作。在“甲型H1N1”流感防控中,在公共卫生伦理原则之间出现了相互冲突的伦理难题。只有遵循公共卫生伦理学中的四大基本原则：效用性原则、尊重原则、共济原则、相称性原则,才能够解决目前出现的难题。解决这些难题对于公共卫生机构和工作人员在应对的行动上有着重大的意义。     

“一＋N”的词汇化与语法化——以“一概”的个案研究为例

“一＋N（名词）”比较容易发生词汇化和语法化。“一概”最初是松散的定中短语,容器和内容没有凸显与否之分;当其高频连用发生词汇化演变为形容词时。凸显的是内容间的“一样,相同”,“一概”的词汇化和语法化都在唐代发生,词汇化只是为语法化提供了一个过渡,所以词汇化的用法没有在现代汉语中保留;当其进一步发生语法化为总括副词时,凸显的是容器的“全部,没有例外”。在“一概”词汇化和语法化的演变过程中,句法、语义和认知三者都在起作用。     

Declining employment success of immigrant males in Sweden: Observed or unobserved characteristics?

Focusing on Nordic and Yugoslavian immigrant males, we study the determinants of employment success of natives and immigrants in Sweden. Furthermore, we investigate the reasons behind the arising gap in employment success between Swedes and immigrants from 1970 to 1990. In a decomposition analysis, we find that the main part of the decline in the employment probability of immigrants relative to Swedes over time is explained by a change in coefficients (unobserved characteristics) rather than a change in determinants (observed characteristics).

一类多时滞中立型控制系统的绝对稳定性

研究了有多个执行机构的多滞后中立型直接和间接Lurie控制系统的绝对稳定性,借助于Lyapunov泛函构造方法,给出了关于Lyapunov泛函中正定矩阵和积分项参数的线性矩阵不等式(LM I)的稳定性判别准则,且与时滞量的大小无关。最后举例说明了本文结果的有效性.     

强N_2-局部连通无爪图的Hamilton性

运用反证法的证明技巧,对任一无爪图G及其圈C,证明了只要C上有一个接触点是强N_2-局部连通的,则C一定不是最长圈.即证明了强N_2-局部连通无爪图是Hamilton图.     

Comparison of dispersal ability between the green leafhoppers,Nephotettix virescens andN. cincticeps (hemiptera: Cicadellidae) by tethered flight

Summary Dispersal propensity of green leafhoppers was compared between a tropical species,Nephotettix virescens, and a temperate species,N. cincticeps. The flight ability was measured with tethered flight technique under laboratory conditions (25°C, 16L-8D). The pre-flight period was shorter and the flight duration was longer inN. virescens than inN. cincticeps in both sexes. No significant correlations were found between the flight activity and morphometric characters for either of the two species. The results suggested that dispersal propensity ofN. virescens is higher than that ofN. cincticeps.     

Comprehensive model for child services: Parent education follow through program

One program which provides comprehensive child and family services is the Parent Education Follow Through Program. Developed at the University of Florida in 1968 by Dr. Ira J. Gordon and moved to the University of North Carolina in 1977, this program is currently implemented in ten diverse communities across the nation, both rural and urban. Using a theoretical ecological framework, the program focuses on the relationship between the home and the school with attention also given to other systems present in the community as well as at the state and national levels. The major features of the program include the following: (1) comprehensive services (social, psychological, and medical); (2) weekly home visitations by paid paraprofessionals during which home learning activities stressing specific parental teaching behaviors are delivered; and (3) parental participation of various kinds including volunteer, employee and decision-maker. The data that have been collected to measure these program areas have shown that the model has had a positive impact upon children's achievement as well as upon their families, the school, and the community.     

The World Bank model for global interdependence: A quantitative framework for the World Development Report

This paper describes the basic structure of the Global Model used in preparing various parts of the World Development Report (WDR) issued annually by the World Bank. The report is designed to help clarify linkages between the international economy and the domestic strategies of developing countries. The paper is divided in four parts. The first two present different aspects of the model structure and discuss the reasons that induced the authors to orient themselves towards given functional specifications. In the final parts the policy relevance of the exercise is studied in light of the results that the model has produced for 1975–1985.     

科学·哲学·文化--兼谈"李约瑟难题”

哲学作为一种世界观是文化的核心,科学作为人们关于自然界的一种系统化、理论化的知识体系与哲学紧密相关,因此,科学、哲学和文化相互匹配,相互影响,相互促进,共同组成了一个有机整体.这就意味着,在不同的文化模式中会诞生不同的科学形态.以此为出发点,作者对所谓的"李约瑟难题”进行了剖析在中国哲学、文化土壤上诞生不出西方意义上的科学就如同鸡蛋里孵不出小鸭一样,是必然的事;同样,由于中国哲学、文化不可能为西方科学提供适宜的养料,所以西方科学这棵大树在中国的土壤上生长得枝枯叶黄.
