It has three co-equal branches of government namely the executive, legislative, and judicial, operating on the principle of check and balance. Issues that had riddled top officials of government remained unresolved hitherto; and, the local government units had their own lingering issues. The government structure therefore did not seem to have the mechanism to correct itself. This paper argues that responses to, as well as the ensuing conditions of the survivors of natural disasters, are affected by how much trust the incumbents of relevant government structures have of each other and that actors outside of the government hierarchy can offer avenues for reform. Tropical Storm Washi that hit Cagayan de Oro City could be a case in point. It left thousands of people dead or missing, millions of dollars in damages, and thousands of internally displaced persons (IDPs). The local government, tasked by the local government code to handle matters related to social welfare, did not seem to have performed as expected. In an apparent lack of trust, donor agencies preferred to course cash and relief items through conduits others than the local government. While the system remained unable to correct itself, the victims of the disaster continued to suffer. Civil society organizations and non-government organizations were trying to re-establish people’s trust in the system through legal measures, and hope that electoral reforms could be instituted.展开更多

Taking the Changjiang(Yangtze) Valley as an example, on the basis of revealing up the integrated mechanism on the formations of its natural disasters and its distributing law, thereafter, the paper relies on the MFIVS technique, adopts two top-down and bottom-up approaches to study a comprehensive division of natural disasters. It is relatively objective and precise that the required division results include three natural disaster sections and nine natural disaster sub-sections, which can not only provide a scientific basis for utilizing natural resources and controlling natural disaster and environmental degradation, but also be illuminated to a concise, practical and effective technique on comprehensive division.展开更多

The results suggest that the length of solar cycle may be a useful indicator for drought/flood and strong earthquakes. When the solar activity strengthens, we see the length of the solar cycle shorten and more floods occur in South China and frequent strong earthquakes happen in the Tibetan Plateau, but the droughts in East China as well as the strong earthquakes in Taiwan and at the western boundary of China are very few. The opposite frequencies occur when the solar activity weakens. The current study indicates that the solar activity may play an important role in the climate extremes and behavior in the lithosphere.展开更多

Risk early-warning factors of natural disasters were differentiated into essential attributes and external characters, and its workflow mode was established on risk early-warning structure with integrated Entropy and DEA model, whose steps were put forward. On the basis of standard risk early-warning DEA model of natural disasters, weight coefficient of risk early-warning factors was determined with Information Entropy method, which improved standard risk early-warning DEA model with non-Archimedean infinitesimal, and established risk early-warning preference DEA model based on integrated entropy weight and DEA Model. Finally, model was applied into landslide risk early-warning case in earthquake-damaged emergency process on slope engineering, which exemplified the outcome could reflect more risk information than the method of standard DEA model, and reflected the rationality, feasibility, and impersonality, revealing its better ability on comprehensive safety and structure risk.展开更多

Particularly in the aftermath of natural disasters, the role of family is considered to play an important and significant role in children with PTSD, either are risk factors or protective ones. In this paper, the literature in relation to the effects of family factors in children with PTSD are reviewed, with the aim of exploring both the risk and protective family factors associated with the PTSD symptoms in children. It is concluded that separation from families, parental psychopathology, and parent maladaptive coping strategies have been suggested o constitute risk factors, whereas positive parental emotionality, warm and open family environment have been found to be protective. Some critiques of PTSD concept, its cross-cultural validity, and assessment of children with PTSD are also revealed in this review.展开更多

This research is helpful to finding effective measures to prevent disasters, avoiding and reducing the harm of natural disasters to industrial and agricultural production. There are 12 disasters in Tianshan Mountains, which can be divided into three zones. (1) Base zone (torrential rain collapse zone): types of the various disasters in this zone are caused by suddenly rain in the low middle mountain of the arid area. The disasters occur mainly from May to August, thus, the frequent periods of their bursts are simultaneous with the maximum period of precipitation in every year. (2) Middle zone (snowmelt water icing zone): most disasters, which happen in the middle high mountain area, have close relation with variation of temperature. (3) Upper zone (snow drift avalanche zone): the movement of snow mantle creates disaster in this zone. The slope direction and height of mountain greatly influence the frequency of hazards and the formation of vertical zone spectrum of natural disasters. Due to the regional diversities of temperature and precipitation, the vertical zone spectrum of natural disasters in mountains are different in different latitude and longitude zones.展开更多

This is an opportunity to recall the long history of this phenomenon in the traditions of different civilizations, to evaluate Chinese efforts, 30-40 years ago, to use this phenomenon for earthquake prediction, and to judge its state of acceptance in modem science. An effort is made to introduce this phenomenon as a research field of modem bionics. The timing is favorable since, increasingly, infrared thermal anomalies, monitored from satellite, suggesting litho-atmospheric processes, are found to precede earthquakes. They were unexpected by seismologists and are here suggested to essentially reflect the energy conversion patterns responsible for the signals monitored by animals. The aim is to learn from animals in the long term how natural disasters can better be anticipated, and how simple technical warning systems can be developed. Some challenges are analyzed. One is interpretation of the nature of energy release prior to the main earthquake disaster resulting in "macro-anomaly" precursors, another is better to understand the effect on animal senses. The role of non-linear cooperative phenomena including tsunamitype waves is emphasized.展开更多

Droughts, floods, and hurricanes are all natural disasters that jeopardize the environment and the lives of Somalis. Severe floods have devastated the south and central parts of the country multiple times, destroying infrastructure and homes and killing many vulnerable people. Droughts in the south and central parts of the country, particularly in the Middle Shebelle region, have killed a number of children and mothers. It also had a negative influence on crops and cattle. Objective of this study is to know the recurrence of Natural Disasters in Jowhar, Middle Shabelle region, Somalia: The Causes and Impacts. The Somali people are completely aware of natural disasters such as droughts and floods, and they are self-sufficient in dealing with the consequences of these disasters. Furthermore, the Somali government has not fully created environmental laws to protect and conserve the environment, and the majority of laws, rules, acts, and regulations are not used or administered effectively. We also found that the Somali government is not yet financially prepared to deal with these crises, and that there are no strategic plans in the central government or even state administrations to prevent or at least control these disasters from causing extreme harm to the community and the environment.展开更多

Most recently, tropical storms Aila, Sidr and Mohaseen have affected the Kuakata coastal belt. These natural disasters have had substantial negative impacts on natural resources. Development of coping strategies for the protection of natural resources across this belt is significantly important. The present research is focused on the effects of tropical storms on crops, humans, fish, livestock and infrastructure. There were 99 fatalities recorded during the Sidr and Aila natural disasters. These disasters impacted 910.94 ha (Sidr) and 973.69 ha (Aila) of cropland. The total number of affected livestock and fishes such as, 18,200 fish ponds, 1209 cattle, 3324 goats, 6888 chickens, 1716 ducks, 103 buffalo and 144 sheep. After tropical cyclones of Sidr, Aila, Heavy rainstorms and Mohaseen 12,970, 17,703, 10,050 and 2500 households respectively reported some form of damage. Cattle, goat, chicken and buffalo were found more injured than other livestock due to the natural disasters of Sidr. Temperature and wind speed were both found to be statistically significant (p ≤ 0.05) with humidity. Climatic parameters trend has been increased significantly since 1979. Regular monitoring of climatic variables, preparedness activities, and coping strategies would be significantly important for this coastal communities.展开更多

Historically, the U.S. emergency response system has not provided psychological support to communities impacted by disasters. Instead, the traditional emergency response community focused on ensuring the physical survival of the individuals and communities that it protects. The goal of all disaster interventions, whether physical or psychological in nature, is to restore the individual to his/her level of pre-disaster functioning. Emphasizing psychological intervention and treatment after disasters is essential in restoring health in individuals post-trauma because mental health is necessary for proper physical health, forming of coping mechanisms, and the ability of individuals to move past the trauma and lead normal lives. At young ages, the body is still developing mentally and physically, meaning the impact of a traumatic event may be completely different from that of most adults. For example, children have greater thought suppression, which leads to an associated increase in PTSD and internalizing behaviors. Thus, children require a different treatment approach to ensure that trauma is not long-lasting and prevalent in future adult life, such as through trouble expressing and regulating emotions, as well as vulnerability to future exposure to stress, which may negatively impact individuals’ identity and interpersonal abilities. The purpose of this review paper is to evaluate various memory-related disorders to then explain the pros and cons of various treatment approaches based on their efficiency in treating PTSD-related symptoms post-natural disasters in children. This review identifies the best pediatric trauma treatment approaches used after natural disasters, highlighting a lack of efficient, effective, and specific psychological treatments. By comparing various existing psychological treatments, this paper provides future directions for research by identifying existing gaps in the field and explains contrasting approaches for various memory-related and natural disaster related psychological trauma disorders.展开更多

文摘The relationship between the length of the solar cycle, a good indicator of long-term change in solar activity, and natural disasters (drought, flood, and strong earthquakes) in China during the last 108 yearsis analyzed. The results suggest that the length of solar cycle may be a useful indicator for drought/flood and strong earthquakes. When the solar activity strengthens, we see the length of the solar cycle shorten and more floods occur in South China and frequent strong earthquakes happen in the Tibetan Plateau, but the droughts in East China as well as the strong earthquakes in Taiwan and at the western boundary of China are very few. The opposite frequencies occur when the solar activity weakens. The current study indicates that the solar activity may play an important role in the climate extremes and behavior in the lithosphere.

The Somali people are completely aware of natural disasters such as droughts and floods, and they are self-sufficient in dealing with the consequences of these disasters. Furthermore, the Somali government has not fully created environmental laws to protect and conserve the environment, and the majority of laws, rules, acts, and regulations are not used or administered effectively. We also found that the Somali government is not yet financially prepared to deal with these crises, and that there are no strategic plans in the central government or even state administrations to prevent or at least control these disasters from causing extreme harm to the community and the environment.
文摘Bangladesh has experienced a number of severe natural disasters. Most recently, tropical storms Aila, Sidr and Mohaseen have affected the Kuakata coastal belt. These natural disasters have had substantial negative impacts on natural resources. Development of coping strategies for the protection of natural resources across this belt is significantly important. The present research is focused on the effects of tropical storms on crops, humans, fish, livestock and infrastructure. There were 99 fatalities recorded during the Sidr and Aila natural disasters. These disasters impacted 910.94 ha (Sidr) and 973.69 ha (Aila) of cropland. The total number of affected livestock and fishes such as, 18,200 fish ponds, 1209 cattle, 3324 goats, 6888 chickens, 1716 ducks, 103 buffalo and 144 sheep. After tropical cyclones of Sidr, Aila, Heavy rainstorms and Mohaseen 12,970, 17,703, 10,050 and 2500 households respectively reported some form of damage. Cattle, goat, chicken and buffalo were found more injured than other livestock due to the natural disasters of Sidr. Temperature and wind speed were both found to be statistically significant (p ≤ 0.05) with humidity. Climatic parameters trend has been increased significantly since 1979. Regular monitoring of climatic variables, preparedness activities, and coping strategies would be significantly important for this coastal communities.
文摘The generation of anthropogenic natural disasters is analyzed firstly,and then the harm of anthropogenic natural disasters is studied.Finally,the measures to prevention anthropogenic natural disasters are proposed,such as facing the status and role of natural resources in social and economic development squarely,actively exploring the development model of harmonizing economy with resources and environment,relying on scientific and technological progress to solve the problem of natural resources,and improving relevant policies,laws and regulations.
文摘What are the best treatment approaches for children experiencing trauma after natural disasters? Historically, the U.S. emergency response system has not provided psychological support to communities impacted by disasters. Instead, the traditional emergency response community focused on ensuring the physical survival of the individuals and communities that it protects. The goal of all disaster interventions, whether physical or psychological in nature, is to restore the individual to his/her level of pre-disaster functioning. Emphasizing psychological intervention and treatment after disasters is essential in restoring health in individuals post-trauma because mental health is necessary for proper physical health, forming of coping mechanisms, and the ability of individuals to move past the trauma and lead normal lives. At young ages, the body is still developing mentally and physically, meaning the impact of a traumatic event may be completely different from that of most adults. For example, children have greater thought suppression, which leads to an associated increase in PTSD and internalizing behaviors. Thus, children require a different treatment approach to ensure that trauma is not long-lasting and prevalent in future adult life, such as through trouble expressing and regulating emotions, as well as vulnerability to future exposure to stress, which may negatively impact individuals’ identity and interpersonal abilities. The purpose of this review paper is to evaluate various memory-related disorders to then explain the pros and cons of various treatment approaches based on their efficiency in treating PTSD-related symptoms post-natural disasters in children. This review identifies the best pediatric trauma treatment approaches used after natural disasters, highlighting a lack of efficient, effective, and specific psychological treatments. By comparing various existing psychological treatments, this paper provides future directions for research by identifying existing gaps in the field and explains contrasting approaches for various memory-related and natural disaster related psychological trauma disorders.
