Evidence against disaster-induced migration: the 2004 tornado in north-central Bangladesh 总被引:2,自引:0,他引:2
Paul BK 《Disasters》2005,29(4):370-385
Migration is generally considered to be one of the primary responses to a natural disaster. The existing literature widely acknowledges the fact that disaster victims migrate from affected areas. This paper, though, provides empirical evidence of the non-occurrence of out-migration in the aftermath of the 14 April 2004 tornado in Bangladesh. Data collected from 291 respondents from eight tornado-affected villages suggest that no one from these locations migrated to other areas. The constant flow of disaster aid and its proper distribution by the government and non-governmental organisations (NGOs) were the main reasons why victims did not leave. This study contributes to the disaster literature by providing three important findings: disasters do not always create out-migration; emergency aid can compensate in monetary terms for damage caused by disasters; and some of the arguments made in the literature against the provision of emergency relief for disaster victims are not always valid for all countries. 相似文献

Managing volunteers: FEMA's Urban Search and Rescue programme and interactions with unaffiliated responders in disaster response 总被引:1,自引:0,他引:1
In the aftermath of disasters it is not uncommon for a large number of individuals, ranging from professional technical responders to untrained, albeit well meaning, volunteers, to converge on site of a disaster in order to offer to help victims or other responders. Because volunteers can be both a help and a hindrance in disaster response, they pose a paradox to professional responders at the scene. Through focus group interviews and in-depth structured interviews, this paper presents an extended example of how Urban Search and Rescue (US&R) task forces, a type of professional technical-responder organisation, interact with and utilise volunteers. Findings show that US&R task forces evaluate the volunteers in terms of their presumed legitimacy, utility, and potential liability or danger posed during the disaster response. Other responses to volunteers such as a feeling of powerlessness or the use of volunteers in non-technical ways are also explored. This paper demonstrates some key aspects of the relationship between volunteers and formal response organisations in disasters. 相似文献

Adequate responses to disasters and emergency situations rely, among other factors, on coping abilities in disaster workers and emergency personnel. In this study, different aspects of disaster-related stressors and training/experience were investigated in Norwegian personnel (n = 581) mobilised for the 2004 tsunami disaster. The level of stress reactions, measured nine to ten months after the tsunami, was relatively low in this sample, indicating that the personnel coped well with the challenges of the disaster. The level of intrusive memories was higher in disaster-area personnel (n = 335) than in home-base personnel (n = 246). Stress reactions were significantly associated with witnessing experiences (disaster-area group) and with having to reject victims in need of help (both groups). Specific preparation for the mission was associated with a lower level of stress reactions in disaster-area personnel. Such factors may be considered in training and preparation programmes for disaster workers. 相似文献

减灾事业的发展和综合减灾 总被引:14,自引:1,他引:14
中国减灾事业的发展史可分3个阶段:第一阶段是新中国成立以前的几千年,减灾活动以赈灾为主,帝王“祭天求恕”,“防灾吏制”,安抚于民。清末民初1800至1949年间计发生巨灾25起,死亡4993万余人,总灾亡则近亿,年均灾亡60万人以上,这段惨痛的灾况记下了十分难得的灾情史,泣血于残野。新中国成立后,在“为人民服务”的思想指导下,为减轻灾害损失,逐步建立了气象、水利、农林、地震、海洋、地质等专业的灾害科技与减灾工程,政府并组织社会兼事抗灾、救灾、应急减灾,国家减灾实力快速增长,已取得突出减灾实效,这个阶段比第一阶段灾亡人数下降了90%以上,但年均灾亡人口仍有1.2万人左右。该阶段的工作特点是以单灾种纵向体系为主,不同灾类的监测、预报水平尚高低不一,这与成灾机理的难易程度和工作条件的强弱有关。21世纪初,随全球增温之势锐升,多类极端灾变遍及各洲,促使许多国家发动全社会人众共同探求“综合减灾”之路;我国政府已迅即开展全社会应急减灾行动,开启了“综合减灾”之先声,这是减灾事业步入第三阶段的先导。综合减灾应该是全社会相关部门和民众的统一行动。目前尚有3个问题需要弄清楚,一是多种自然灾害之间成灾机理相关性的研究,其对象是灾害群与灾害链;二是全社会减灾要素综合运作预案的优选;三是如何核算减灾投入与社会可持续发展之正、负效应关系。 相似文献

自然灾害的自相似性质 总被引:6,自引:1,他引:6
本文分析了多种自然灾害的致灾因子和致灾损失的频次—大小关系,结果表明,普遍服从幂指数分布律,表明存在自相似性和可用分数维度量。地震和洪水等突发性灾害及其造成的损失自相似最明显,分数维可在2~3个量级区间成立。不同文种、致灾因子和致灾损失的分数维值似与成灾机理、影响因子的复杂程度有关. 相似文献

The starting-point of this paper is the assumption that credibility and the right to be heard are differentially distributed in any social system and therefore a 'hierarchy of credibility' exists. To test this, the media coverage of the Love Canal, New York, hazardous waste landfill disaster and six other disasters was examined to determine if this hierarchy exists in all cases. A hierarchy of credibility emphasising the views of established news sources with routine and habitual access to the media was demonstrated in the majority of events examined. However, the Love Canal disaster was one of two where this hierarchy was disrupted due to a number of factors. These included the contentious or political nature of the event, its duration, the extent of competition for credibility and coverage among news sources, the extent of information shortage, the type of news medium, the degree of sympathetic and representational salience of victims and the extent to which they organised and achieved status as 'newsmakers'. Building on disaster research, a model of the operation of the credibility hierarchy in coverage of disasters is presented and discussed. 相似文献

This paper explores the effectiveness of the nuclear disaster management system in Taiwan via a review of the third (Maanshan) nuclear power plant. In doing so, the Fukushima Daiichi nuclear disaster in Japan on 11 March 2011 is reviewed and compared with the situation in Taiwan. The latter's nuclear disaster management system is examined with respect to three key variables: information; mobilisation; and inter‐organisational cooperation. In‐depth interviews with 10 policy stakeholders with different backgrounds serve as the research method. The results point up the need for improvement in all dimensions. In addition, they highlight three principal problems with the nuclear disaster management system: (i) it might not be possible to provide first‐hand nuclear disaster information immediately to the communities surrounding the Maanshan facility in Pingtung County, southern Taiwan; (ii) the availability of medical resources for treating radiation in Hengchun Township is limited; and (iii) the inter‐organisational relationships for addressing nuclear disasters need to be strengthened. Hence, cooperation among related organisations is necessary. 相似文献

基于链式理论的单灾种向多灾种演绎 总被引:1,自引:0,他引:1
从灾变链角度出发,以灾变链式理论的八种链式形态为依托,基于耗散结构理论,指出自然灾害系统链式响应行为是外部环境复杂输入和自身内部结构关系变化两方面共同作用的结果;构建系统的单灾种模型,并推演出多灾种模型,反映各灾种之间的耦合关系和相互影响,探讨单灾种向多灾种的演化机理.研究表明各灾变链致灾因子所具有的能量是灾变链式阶段的关键,在此基础上提出防灾减灾策略,为单灾种和多灾种灾害的防治提供参考依据. 相似文献

Injury prevention in natural disasters. A theoretical framework 总被引:1,自引:0,他引:1
A theoretical framework for conceptualizing injury patterns in natural disasters is described. In this conceptual framework, natural disasters are divided chronologically into predisaster, disaster and postdisaster phases. Within each phase, four factors (human, engineering/technological, physical environmental and socioeconomic) are identified that play an important role in the causation of injury. By combining these phases and factors into a three by four matrix, one may begin to identify points in the natural history or evolution of a disaster that may be amenable to therapeutic or preventive intervention. The application of this proposed three-phase matrix model to a disaster will permit researchers to reduce a large, complex problem into more manageable, conceptually simpler parts. It may also be of value to disaster planners by suggesting preventive and mitigation measures, as well as aiding in the setting of priorities so that scarce resources can be allocated to achieve maximum reduction of injuries. 相似文献

This paper explores how social networks and bonds within and across organisations shape disaster operations and strategies. Local government disaster training exercises serve as a window through which to view these relations, and ‘social capital’ is used as an analytic for making sense of the human relations at the core of disaster management operations. These elements help to expose and substantiate the often intangible relations that compose the culture that exists, and that is shaped by preparations for disasters. The study reveals how this social capital has been generated through personal interactions, which are shared among disaster managers across different organisations and across ‘levels’ within those organisations. Recognition of these ‘group resources’ has significant implications for disaster management in which conducive social relations have become paramount. The paper concludes that socio‐cultural relations, as well as a people‐centred approach to preparations, appear to be effective means of readying for, and ultimately responding to, disasters. 相似文献
