非洲商人迁移广州的行为特征分析

全球化背景下,非洲的巨大进口需求和中国商品的出口需求得到完美互补,从而极大地促进了中非贸易,也吸引了众多的非洲商人到广州采购日用品,这其中不仅有非洲国际商人,也有“淘金者”.文章研究表明,无论非洲国际商人,还是“淘金者”,他们都是经过利益比较后才到广州的,他们迁移广州的行为是理性选择的结果.网络关系在他们的迁移过程中起着重要作用,但强弱关系扮演的角色不同,在迁移的决定过程中信息等弱关系起着重要的作用,而在迁移后的适应过程中,强关系则扮演着至关重要的作用,此外,关系网络的范围越大也越有利于他们适应广州社会     

从“整理”到“重构”——论民间文学在作家文学中的传承与渗透

结合古今中外文学实例,论述了民间文学这一文学形态在作家文学中所处的地位及表现形式;认为创作正统文学的作家主动吸收或改造民间文学的成分,并在其作品中按作者的意愿发挥作用;经典作家作品中民间文学的出现大致有整理、引用、转述、融汇、重构等形式。

供应链环境下基于顾客需求响应的过程质量模型研究

供应链作为一个系统,整合了包括从原材料的获取一直到最终顾客交付之间的一系列的业务活动。其基本目标是在核心企业的主导下,在正确的时间按正确的数量将正确的产品交付给顾客,并保证总成本最小。为了保证整个供应链系统所有构成都能有效运行,本文开发一个基于顾客需求响应的过程质量模型(Process Quality Reaction Customer Model,PQRCM),通过测量、评估、改进和控制,为实施和改进供应链系统的质量规划提供了一种结构化的方法。     

恐怖主义与霸权主义关系探微

恐怖主义与霸权主义是当今世界和平与发展的两大威胁 ,都是祸害世界的毒瘤。恐怖主义与霸权主义既可能彼此敌对、互相制约 ,又可能相互结合、彼此利用 ,二者源远流长 ,在互动中发展。反恐与反霸并举是促进世界和平与发展的根本要求。中国一贯坚持既反恐又反霸的政策 ,是维护世界和平的坚定力量。

Positive Reaction to Disclosure and Recovery from Child Sexual Abuse

ABSTRACT

Factors associated with improvement in the behavioral-emotional functioning of sexually abused children, from 6 to 18 years of age, were investigated. Children were classified by their therapist according to current level of disclosure regarding past abuse. Ratings of degree of support offered by significant people in the children's lives were also made. Findings showed children who were in an actively disclosing stage to be exhibiting significantly less externalizing behavior problems than non-disclosing children. Children who were fully disclosing without recantation showed significantly lower dissociation than did all other subjects. Children who recanted with or without re-disclosure showed significantly more post-traumatic stress symptomatology. As all the subjects were in foster care, the reactions to disclosure of foster parents proved to be most salient with respect to current functioning. Children who received full support from foster parents showed significantly lower depression scores than did children who received only partial support.

Other significant findings pertain to the effects of time since initial disclosure, age of subjects, and type of sexual abuse on behavioral-emotional functioning. Implications for developing structured training programs for foster parents and their caseworkers are discussed. Recommendations are made for future study using the present design with a non-foster care population and investigating the effect that the timing of supportive reactions to disclosure has.

熔渗反应法制备金刚石/SiC复合材料

为制备金刚石/SiC复合材料,采用熔渗反应法,在真空环境和烧结温度为1500 -1 600℃的条件下进行制备。 分析了复合材料的致密度、硬度和在不同温度下的干摩擦磨损性能。结果表明,熔渗反应工艺制备的复合材料致密度 高,烧结温度为l 550℃时得到的复合材料的硬度最高。反应烧结金刚石/SiC复合材料常温下的耐磨损性较好,但600 ℃下的磨损性能显著恶化
