Recent research in both the social and natural sciences has been devoted to increasing our ability to predict disasters, prepare for them and mitigate their costs. Curiously, we appear to know very little about the fiscal consequences of disasters. The likely fiscal impact of a natural disaster has not been examined before in any comparable or comparative framework. We estimate and quantify the...
BACKGROUND Environmental public health disasters involving hazardous contaminants may have devastating effects. While much is known about their immediate devastation, far less is known about long-term impacts of these disasters. Extensive latent and chronic long-term public health effects may occur. Careful evaluation of contaminant exposures and long-term health outcomes within the constraints...

OBJECTIVE To evaluate the pathway of leaded dust from a lead-zinc-copper mine to houses of employees, and the impact on blood lead concentrations (PbB) of children. METHODS High precision lead isotope and lead concentration data were obtained on venous blood and environmental samples (vacuum cleaner dust, interior dustfall accumulation, water, paint) for eight children of six employees (and t...
Information is needed to support humanitarian responses in every phase of a disaster. Participants of a multilateral working group convened to examine how best to meet these information needs. Although information systems based on routine reporting of diseases are desirable because they have the potential to identify trends, these systems usually do not deliver on their promise due to inadequat...
In the aftermath of many disasters the silence is punctuated by the crying of infants, hungry infants. The aim of this paper is to discuss ethical issues in feeding infants after disasters. The Asia Pacific region generates 25% of the world's GDP, but experiences 45% of natural disasters and 42% of the economic losses due to disasters. The region has 61% of the world's population, but 86% of th...
Based on unascertained measurement theory, a comprehensive evaluation method to propose the vulnerability of regional geological disasters was presented in this paper. The function of unascertained measure of all evaluation indexes was established, the weights for indexes was calculated by entropy weight theory, and a result of the vulnerability of regional geological disasters has been carried...
In order to analyze the deformation of old goaf in Dameidong Coal Mine and its influence on surrounding rock soil layer, it provides guidance for prevention control geological disasters region. this paper, transient electromagnetic method numerical simulation were used study law overlying strata mining area. The results detection showed that subsidence area was within range elliptical water-ric...
Throughout history mankind has been subject to disasters produced by " Mother Nature " as well as the man-made variety. Only recently, however, have economists understood disasters as economic phenomena to be formally analyzed. Given the magnitude of many recent disasters, their impact on local, regional, and national economies, and the coverage of their consequences in the popular press, it is...
Gas explosion and gas-coal dust are serious disasters in coal mine production. To further study the hazards of gas under different conditions, experiments were done this paper a pipeline system containing an pressure relief pipeline. Flame propagation behavior overpressure dynamics analyzed. divided into three stages: spherical flame, round-finger pointed-finger flame. front position increases ...
