高速公路cfg桩复合地基褥垫层作用机理研究
,洪宝宁,丘国锋
岩土力学 , 2004,
Abstract: cfg桩(cementfly-ashgravelpile)复合地基的核心技术是设置褥垫层,而褥垫层设计的是否合理,对cfg桩复合地基的承载与变形特性都产生较大的影响。根据太沙基基本理论,详细地讨论了cfg桩复合地基褥垫层作用机理,并推导出cfg桩复合地基最佳桩间距、合理褥垫层厚度、桩土应力比、实际置换率的解析表达式。计算结果与工程实例对比表明了该解答的可行性,能够为cfg桩复合地基的优化设计提供帮助与指导。
馆藏建设经费使用效率的评价与控制

图书情报工作 , 2005,
Abstract: ?分析馆藏建设经费使用效率评价的困难及其负面影响,探讨馆藏建设投入与有效服务率之间的量化关系及无效投入的原因,讨论馆藏建设经费使用效率的控制,认为根据读者需求分配馆藏建设经费,统计各类文献的老化率,借鉴国外的做法是合理分配馆藏建设经费的有效途径。
产业集群组织间关系密集性的社会网络分析
蔡宁 ,
浙江大学学报(人文社会科学版) , 2006,
Abstract: ?产业集群中组织间关系的类型和性质是理解产业集群现象的重要基础.通过社会网络分析方法考察集群组织间关系网络的密集性质及其功能机制发现:(1)受到连接多样性、连接偏好和集群生命周期的影响,产业集群网络关系密集性呈不均匀分布,使得集群网络呈现出密集和稀疏相结合的结构特征;(2)集群组织间关系密集性具有资源配置优势,但同时使网络隐藏着潜在的风险,而稀疏网络具有资源获取优势和鲁棒性作用;(3)网络关系密集性和稀疏性的不断重构共同推动了集群的发展演化,此分析有助于提供更具针对性的网络治理对策.
消费者社会价值导向下社会责任与企业利润的统一
The unification of corporate social responsibility and profit based on consumers’ social value

- , 2015, DOI: 10.11835/j.issn.1008-5831.2015.03.011
Abstract: 针对企业履行社会责任的现实困惑与理论争议,文章从消费者社会价值分析出发,探讨义利统一的企业社会责任实现条件与实践模式,提出“识别和选择消费者社会价值”、“企业创新实践”和“盈利性评估”的战略行动框架,并基于“天府农业信息网”的本土案例剖析了这一战略模式及其效果。文章的研究为中国社会转型背景下企业实践社会责任提供了一个基本的分析工具,同时也为未来的战略性企业社会责任研究提供了有益借鉴。
Aiming at the debate of corporate social responsibility, we develop a practice mode based on analysis of consumers’ social value, which connects CSR with corporate profits directly. This mode requests firms identify consumers’ social value, develop new methods and analyze profitability. Such efforts, not only solve social problems but also create the foundation for more affluent and dynamic markets, which ultimately produce greater profits for business.

微生物学报 , 2007,
Abstract: To construct a helper-dependent adenoviral vector expressing human respiratory syncytial virus (RSV) subgroup A F gene, and finish large scale preparation, purification and identification of the vector. F gene under the control of CMV promoter was subcloned into a shutle vector pSC11, and then cloned into HADd plasmid pSC15B. The HDAd/F genome was liberated by removing the bacterial sequences from the resulting plasmid pSC15B/F digested with restriction enzyme Pme I, and then the linear HDAd/F DNA was transfected into 293Cre4 cells with calcium phosphate transfection method. The cells were infected by helper virus 16 hours after transfection. HDAd/F was amplified by serial coinfection of 293Cre4 cells by helper virus and the crude lysates from previous passage until it reached plateau of amplification by BFU staining of parallel amplified control vector pSC9A. HDAd/F was purified by CsCl gradient ultracentrifugation and expression of F protein was identified by RT-PCR and Western blot. HDAd/F was constructed, purified successfully. The expression of F protein was detected. The successful construction and preparation of HDAd/F is the foundation for the further investigation of potential immune protection in vivo and opens a new window for the RSV vaccine research.
