Travelling without a helmet: tourists' vulnerabilities and responses to disasters in Indonesia

Tourists are particularly vulnerable when natural disasters occur in regions that they are visiting. It is assumed that they lack awareness and understanding of the actions that they need to take in such circumstances. This study examines the responses of tourists in times of disaster, building on empirical data collected through large‐scale surveys conducted in Bali and Yogyakarta, Indonesia, in 2015. Both are important tourist destinations in the country that have suffered major disasters in recent years. The different types of responses to these events are framed using a grid/group analysis stemming from cultural theory. The study resulted in three key findings: (i) current disaster management planning largely follows a single rationale; (ii) tourists are not a homogeneous group, but rather a complex, diverse, and dynamic body of stakeholders; and (iii) the focus of disaster management planning should shift from a single rationale to a polyrational methodology. Disaster managers need to consider, therefore, these different aspects in the context of preparedness.     

Natural hazard events and social capital: the social impact of natural disasters

This study investigates if and to what extent natural disasters affect social capital. Twelve different events in Europe are examined in a quantitative analysis, using data derived from the European Social Survey and the EM‐DAT International Disaster Database. The study uses social trust as an indicator of social capital and offers evidence that a change in social trust is a possible occurrence during or after a disaster, but that it is not an inevitable consequence of it. The results reveal that social trust decreases after a disaster with a death toll of at least nine. Changes in social capital, therefore, are found to be more probable as the severity of the event increases. National, rather than regional, disasters lead more frequently to significant shifts in social trust. This evaluation of 12 separate cases pinpoints several disasters that have had an effect on social trust, but it does not identify any general patterns, underlining the significance of contextual dependency.     

复合动力灾害条件下孤岛工作面区段煤柱宽度留设研究

孤岛工作面覆岩空间结构复杂多变,受开采和地质等因素的影响在开采过程中面临冲击地压、煤与瓦斯突出、自燃发火以及采空区突水等复合动力灾害。留设合理宽度的区段煤柱是确保工作面安全开采的关键,以陕西某矿特厚煤层孤岛工作面开采为工程案例,通过分析工作面覆岩空间结构,理论计算了工作面应力分布;采用应力动态监测等方法确定了该工作采空区侧向覆岩运动,并综合考虑冲击地压灾害防治、次生灾害控制以及巷道支护等因素,确定了该工作面区段煤柱的合理宽度为5~7 m。     

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.
