地震应急避难需求的系统动力学研究

为定量研究地震应急避难人群的规模及变化规律,建立需求分析的系统动力学模型。该模型包括建筑物倒塌,断水和电梯停运3种因素造成的需求。参考汶川地震中板房建设速度和电梯修复速度,以及日本关于地震断水率的研究成果,建立非线性模型拟合各需求的变化规律。采用Vensim软件建立系统动力学模型,分析各需求的综合变化规律。采用上海市徐汇区的数据进行案例演算,并与其他研究方法对比分析仿真误差。仿真结果表明:建筑物损坏对人群数量的影响很大,但是灾后1个月内断水的影响最大;相对于工程技术因素,人因对需求有重要的影响。     

Towards emergency management of natural disasters and critical accidents: the Greek experience

This paper presents the findings of a prototype study which sought to identify factors that contribute to effective emergency management in Greece and other European states regarding both natural disasters and critical accidents. The parameters for proper action and successful intervention in operational and logistical are identified based on the document analysis and interviews with emergency responders. The interviews are conducted between state-owned and voluntary organizations. They were asked to rate in terms of their importance for effective emergency response efforts. This paper offers useful information of the organization and management of emergency response in Greece, as well as provides interesting responders' opinions data concerning important priorities in the emergency management area. Despite the fact that the data come from the Greek experience, the conclusions may be applied for a broader use in the emergency planning of disasters. The whole study has been undertaken within the European Pre-Emergencies (PreEm) project.     

基于对抗交叉评价模型的中国自然灾害区域脆弱性评价

首次提出使用对抗交叉评价（Aggressive-Cross-Evaluation）模型对自然灾害的区域脆弱性程度进行研究。从区域自然灾害的危险性,区域承灾体暴露性和区域自然灾害造成的损失程度构建了区域自然灾害系统的脆弱性评价模型,并通过算例对中国自然灾害的区域脆弱性进行了评价。传统的DEA方法为了保证算法的有效性,一般选取的输入和输出指标的个数较少。对抗交叉评价模型回避了传统的DEA方法的缺陷,继承了DEA方法不需要预先估计权重参数和函数模型的优点,可以全面、客观地评价自然灾害的区域脆弱性。     

Supporting breastfeeding in emergencies: protecting women's reproductive rights and maternal and infant health

Women have the right to support that enables them to breastfeed. Supporting breastfeeding in emergencies is important because artificial feeding places mothers and children at risk. In emergencies, artificial feeding is dangerous to the infant, difficult and requires substantial resources. In contrast, breastfeeding guards infant health. It is also protective against postpartum haemorrhage, maternal depletion, maternal anaemia and closely spaced births and should therefore concern not only nutritionists, but also those involved in reproductive health. However, it is common for women's ability to breastfeed to be undermined in emergencies by the indiscriminate distribution of breast-milk substitutes and the absence of breastfeeding support. Controlling the distribution of breast-milk substitutes, providing supportive environments, and appropriate medical and practical assistance to breastfeeding women safeguards the health and well-being of mothers and babies. Greater collaboration between the nutrition and reproductive health sectors is required to promote best practice in protecting breastfeeding women and their children in emergencies.     

Establishing moral bearings: ethics and expatriate health care professionals in humanitarian work

Expatriate health care professionals frequently participate in international responses to natural disasters and humanitarian emergencies. This field of practice presents important clinical, logistical and ethical challenges for clinicians. This paper considers the ethics of health care practice in humanitarian contexts. It examines features that contribute to forming the moral landscape of humanitarian work, and discusses normative guidelines and approaches that are relevant for this work. These tools and frameworks provide important ethics resources for humanitarian settings. Finally, it elaborates a set of questions that can aid health care professionals as they analyse ethical issues that they experience in the field. The proposed process can assist clinicians as they seek to establish their moral bearings in situations of ethical complexity and uncertainty. Identifying and developing ethics resources and vocabulary for clinical practice in humanitarian work will help health care professionals provide ethically sound care to patients and communities.     

云南气象灾害的时空分布规律

云南主要的气象灾害有旱灾、洪灾、冷灾、雹灾、风灾和雷灾等6类,它们造成的经济损失超过地震灾害和地质灾害,是云南最大的自然灾害.6种主要气象灾害有明显的时空分布特征.旱灾区主要集中在滇东北、滇东、滇北和滇中地区;洪灾区主要集中在滇东北、滇东南、滇南和滇西南地区;冷灾区主要分布在滇东北、滇西北、滇东和滇中地区;雹灾区主要分布在滇东北、滇东、滇南、滇西北以及滇中局部地区;风灾区主要集中在滇东北、滇南地区;雷灾区主要集中在滇南、滇东南及滇北局部地区.旱灾以春季和初夏最为严重,洪灾主要出现在夏季和秋季,冷灾主要出现在冬春季和夏季,雹灾主要出现在春季和夏季,风灾主要出现在春季和夏季,雷灾主要出现在夏季和春季.     

我国旱涝空间型的马尔科夫概型分析

旱涝灾害在我国是影响最大、也最为频繁的气候灾害。本文利用马尔科夫概型分析的原理和方法，在验证了我国旱涝空间型序列具有马尔科夫性质的基础上，计算出各状态的转移概率，进而分析了旱涝空间型序列的静态和动态结构，并揭示出旱涝空间型各状态演化的优势倾向。     

四川沐川—马边（1994—12—30）5.5级地震山地灾害类型研究

地震诱发的次生山地灾害类型包括：崩塌、滚石、滑坡和重力地裂缝。其规模为中、小型，但类型较多，分布密集，造成不同程度危害。按照危险性区划，震区可划分为高、中、低三种山地灾害危险度区域。各区域面积为：ＵＤ＝９．４ｋｍ＾２；ＭＤ＝２５．９ｋｍ＾２；ＬＤ＝４０．４ｋｍ＾２。斜坡可分为梯状破坏模型：①Ｒｃ崩塌、滚石阶梯；②Ｌｄ滑坡阶梯；③Ｇｆ重力地裂缝阶梯。
