中美灾后重建对比研究——以美国格林斯堡镇与中国汶川灾区为例

通过对美国格林斯堡镇与我国汶川灾区灾后重建工作进行对比,比较其规划制定流程、内容及执行过程的异同,并对重建效果进行分析.分析显示,1)在规划制定方面,美国采取"自下而上"方式,我国采取"自上而下"方式;2)在规划内容方面,美国以细节到整体的积累方式形成,我国以从框架到内容的填充方式完成;3)在执行过程中,美国的政府、社区、非盈利机构、基金会等组织合作密切且公众参与度高,我国采用的对口支援政策有利于集中优势以提高工作效率.     

Radiation protection of pronormoblasts and normoblasts by 2-mercaptopropionylglycine (MPG)

Summary The pronormoblasts and normoblasts in Swiss albino mice were found to be very sensitive to radiation and their percentage was reduced drastically after exposure to gamma-rays. The degree of damage increased with increase in radiation dose. MPG reduced the initial damage and brought about an early and fast recovery. It is concluded that the drug protects the stem cells and thereby reduces the depletion of the regenerating pool which causes a more efficient and accelerated recovery.     

灾后重建中的资金来源及有效性对比研究———以美国绿堡镇与中国汶川灾区南坝镇为例

以美国堪萨斯州绿堡镇龙卷风灾区和中国汶川地震灾区灾后重建工作为例,选择具有代表性的两个研究区——美国堪萨斯州绿堡镇和四川省平武县南坝镇为研究区,从宏观和微观角度出发,采用文献研究、问卷调查和数据统计分析的方法,对比分析二者在资金来源及使用成效在当地灾民认知方面的异同,并分析差异形成的可能原因,以期为中国灾后恢复重建工作的顺利展开提供借鉴和理论指导.     

Modification of radiation-induced spleen weight changes in mice by 2-mercaptopropionylglycine

Summary It was found that the MPG partially protects the spleen against weight loss due to radiation, and exaggerates the compensatory reaction in the tissue during recovery. It is also concluded that MPG protects the stem cells in the spleen, which helps to restore the peripheral blood by extramedullary erythropoiesis.     

基于统计建模与随机事件仿真的农作物冰雹灾害风险评估——以河北省为例

通过整理河北省1949—2000年间的冰雹灾害农作物损失的案例资料,利用统计仿真模拟软件Arena和Matlab等,分析了河北省农作物冰雹灾害年发生次数以及农作物损失(分为受灾、成灾、绝收3种程度)服从的统计规律,并依据统计反演得到的参数进行了冰雹灾害随机事件模拟,对河北省冰雹灾害风险进行了评估,发现河北省冰雹灾害造成的年均农作物单产损失约合1.9%.     

自然灾害下的应急物流协调研究

结合目前自然灾害应急物流的研究现状,指出了应急物流存在的问题.从物资需求、分配原则、路网风险以及配送方式的角度,分析了应急物流的特性.提出了自然灾害应急物流协调框架,它是灾害综合评估、灾民转移和应急物资配送在应急物流系统下的有机结合,是不同组织机构、不同利益主体、不同物流网络单元间职能、目标、信息、物资、车辆等的协调.

Radiation protection of bone marrow lymphocytes by 2-mercaptopropionylglycine (MPG)

Summary The drug, MPG, when administered before irradiation, increases the radioresistance of bone marrow lymphocytes of mice to gamma rays and helps in promoting fast recovery, especially when exposed to sublethal dose.
