1—氯代正烷烃凝聚型性能的拓扑化学研究     

王克强 《嘉应学院学报》1995,(1):85-89

本文用拓朴方法探讨了1—氯代正烷烃的凝聚型性能与其分子结构之间的关系,提出一个普遍适用于1—氯代正烷烃凝聚型性能的定量关系式。对沸点、密度和折光指数的计算结果表明,计算值都很接近实验值。应用这一定量关系,不仅能够合理表征1—氯代正烷烃的结构性能关系,而且有助于揭示物质结构与性能关系之间的奥秘。  相似文献

Parental Explanatory Models of Child’s Intellectual Disability: a Q Methodology Study     

Aesha John  Diane Montgomery 《International Journal of Disability, Development & Education》2016,63(3):293-308

This study with families caring for an individual with an intellectual disability in a mid-sized Indian city explored the diverse explanatory models that parents constructed of causes, preferred treatment approaches and perceived social effects of their child’s intellectual disability. Seventeen mothers and three fathers rank ordered 48 disability related statements and participated in a qualitative interview. The intercorrelations and factor analysis of participant sorts helped to generate three parental explanatory models which were named religious resilience, in search of treatment and social change, and it is a burden to bear. The three models extracted 23%, 20% and 9% variance respectively. Interpretations based on factor arrays, consensus and differentiating statements, and qualitative interviews indicated that the first explanatory model utilised religion and spirituality to positively frame their child’s intellectual disability. The second explanatory model rejected religious notions and did not dwell on the cause of disability, but rather focused on optimal rehabilitation of individuals with an intellectual disability. The third model was characterised by maladaptive religious attributions and rehabilitation approaches.  相似文献   

“客商”与近现代中国     

闫恩虎 《嘉应学院学报》2008,26(1):5-9

"客商"由传统商帮发展成为今天跨国界的实业家组织,在近现代为国家复兴与建设作为了杰出贡献。"客商"不仅是"实业救国"和"实业兴国"的重要力量,而且也是近现代民主革命和国家建设的积极支持者;"客商"为中国传统"儒商"文化的现代转型作出杰出贡献,是现代"儒商"文化的积极践行者;"客商"也是近现代"华商"网络的倡建者和积极推动者。新时期经济全球化竞争的进一步加剧,要求当代"客商"同所有华商一起,共同弘扬优秀儒商文化,团结合作,树立爱国济世、诚实守信、自律自强的儒商情怀,提高竞争与发展素质,为国家富强和民族自强而继续奋斗。  相似文献   

论财权安排的企业治理逻辑基础和实现机制     

徐铁祥 《岳阳职业技术学院学报》2005,20(1):41-44

财权是现代企业财务治理结构与财务理论体系的核心概念。在我国,长期以来人们对财权的认识和理解都比较片面和表面化。本文从“企业是一个人力资本与非人力资本的特别合约”角度入手,分析了完整与本质意义上的企业财权概念,在此基础上论析了财权安排的企业治理逻辑基础是人力资本所有者与物质资本所有者的双边治理,最后论述了财权的具体安排及其实现机制。  相似文献

彭永贵 《北京教育学院学报》2007,21(3):48-52

自1979年恢复国内保险业务以来,中国保险业进入了快速、持续增长时期,无论在保费收入、保险公司数量、保险深度和保险密度、保险中介机构数量、险种、保险资金运用渠道等方面还是在保险法规与监管制度建设方面都获得了长足的发展。与此同时,一些制约中国保险市场发展的现象和因素也逐渐暴露、积累。本文旨在对这些现象、因素进行分析,寻找解决方法,以促进中国保险业能够健康、可持续的发展。  相似文献   

K/Na-Mo复合变质对M2高速钢组织和性能的影响     

侯晓霞 《德州学院学报》2008,24(2):57-59

用K／Na-Mo复合变质剂对M2铸造高速钢进行变质处理,对试样进行组织分析及力学性能测试．结果表明,随着K／Na-Mo复合变质剂的加入,M2高速钢中铸态碳化物趋于断网,骨状晶转变为等轴晶,组织得到了优化,同时M2高速钢的韧性明显提高,硬度和红硬性也有所改善．  相似文献   

Transition services for students with intellectual disabilities: School psychologists’ perceptions     

Devadrita Talapatra  Andrew T. Roach  Kris Varjas  David E. Houchins  Daniel B. Crimmins 《Psychology in the schools》2019,56(1):56-78

For individuals with intellectual disabilities (ID), transition services increase access to postschool opportunities. School psychologists should contribute to transition services but have reportedly limited involvement in this area. This study distributed a national survey (N = 176) assessing school psychologists’ current knowledge, attitudes, and behaviors regarding transition services for students with ID. Results indicated that attitudes toward and knowledge of the ID population were significant predictors of transition task performance, and knowledge was a significant predictor of transition‐related attitudes and behaviors. The results provided preliminary evidence that increasing school psychologists’ specific knowledge of transition services and encouraging positive attitudes toward the transition needs of students with ID may increase school psychologists’ performance in transition practice. Specific recommendations are provided.  相似文献
