Although there are several studies looking at the effect of natural disasters on economic growth, less attention has been dedicated to their impact on educational outcomes, especially in more developed countries. We use the synthetic control method to examine how the L’Aquila earthquake affected subsequent enrolment at the local university. This issue has wide economic implications as the University of L’Aquila made a large contribution to the local economy before the earthquake. Our results indicate that the earthquake had no statistically significant effect on first-year enrolment at the University of L’Aquila in the three academic years after the disaster. This natural disaster, however, caused a compositional change in the first-year student population, with a substantial increase in the number of students aged 21 or above. This is likely to have been driven by post-disaster measures adopted in order to mitigate the expected negative effects on enrolment triggered by the earthquake.

By providing a wide literature review, post-hurricane Katrina uneven urban regeneration in New Orleans is presented here by framing it within a historical perspective in order to underline how environmental threats too often seem to be not so much “natural” but rather man-made as well as to highlight both the reasons and the ways in which, in post-disaster reconstruction, competitive growth has been valued over equity, by directly benefiting those who were already the most advantaged. The aim is to highlight how environmental disasters can be considered as socially constructed phenomena, as they cannot be seen as a single event but rather as a process made by a series of progressive steps occurring within different spheres, which do not necessarily concern the environment only.

Natural disasters in Argentina and Chile played a significant role in the state-formation and nation-building process (1822-1939). This dissertation explores state and society responses to earthquakes by studying public and private relief efforts reconstruction plans, crime and disorder, religious interpretations of catastrophes, national and transnational cultures of disaster, science and technology, and popular politics. Although Argentina and Chile share a political border and geological boundary, the two countries provide contrasting examples of state formation. Most disaster relief and reconstruction efforts emanated from the centralized Chilean state in Santiago. In Argentina, provincial officials made the majority of decisions in a catastrophe’s aftermath. Patriotic citizens raised money and collected clothing for survivors that helped to weave divergent regions together into a nation. The shared experience of earthquakes in all regions of Chile created a national disaster culture. Similarly, common disaster experiences, reciprocal relief efforts, and aid commissions linked Chileans with Western Argentine societies and generated a transnational disaster culture. Political leaders viewed reconstruction as opportunities to implement their visions for the nation on the urban landscape. These rebuilding projects threatened existing social hierarchies and often failed to come to fruition. Rebuilding brought new technologies from Europe to the Southern Cone. New building materials and systems, however, had to be adapted to the South American economic and natural environment. In a catastrophe’s aftermath, newspapers projected images of disorder and the authorities feared lawlessness and social unrest. Judicial and criminal records, however, show that crime often decreased after a disaster. Finally, nineteenth-century earthquakes heightened antagonism and conflict between the Catholic Church and the state. Conservative clergy asserted that disasters were divine punishments for the state’s anti-clerical measures and later railed against scientific explanations of earthquakes.

The main objective of this paper is to identify some of the key issues encountered by tsunami-affected small and medium-sized enterprises (SMEs) in the process of rehabilitation and re-establishment in Sri Lanka. The second objective is to assess how far these affected industries have received various benefits and supports from bodies such as government agencies, private sector firms, donors and NGOs to help them get back into business. The final objective is to recommend policies and strategies to develop the tsunami-affected SMEs in a self-sustaining manner and within a certain time period. The main database of firms for this research has been obtained from the Industrial Development Board, which conducted a survey covering 4,389 tsunami-affected micro- and SMEs. In addition to this, information from various state organizations and NGOs-based sources has been used. This paper identifies the main issues related to tsunami-affected SMEs ranging from basic infrastructure provision up to finance, marketing, machinery, technology, training, product identification and development and so forth. In fact, it is shown that there are no significant differences between issues faced by SMEs in general and tsunami-affected SMEs, apart of course from the effects of a sudden disaster (the tidal wave). Consequently, these issues can be generalized as issues relevant to SMEs in Sri Lanka as a whole. However, under the flood and rain of local and foreign assistance, there have been more pledges and promises than actual deliveries and, so, tsunami-affected SMEs have received comparatively little support and assistance in recovering and no records can be found as to where the colossal amount of foreign assistance received has actually gone. Finally, this paper recommends various types of business incubator centres and entrepreneurial enhancing skill programmes for the revamping of tsunami-affected SMEs in addition to the normal disaster risk management plan.

Solid earth simulations have recently been developed to address issues such as natural disasters, global environmental destruction and the conservation of natural resources. The simulation of solid earth phenomena involves the analysis of complex structures including strata, faults, and heterogeneous material properties. Simulation of the generation and cycle of earthquakes is particularly important, but such simulations require the analysis of complex fault dynamics. GeoFEM is a parallel finite-element analysis system intended for solid earth field phenomena problems. This paper describes recent development in the GeoFEM project for the simulation of earthquake generation and cycles.

Na presente dissertação pretende-se compreender como é que a comunicação do risco é considerada pelos profissionais ligados à gestão do risco no domínio das calamidades naturais em Portugal. Para tal, além da fundamentação teórica acerca do objeto de estudo deste trabalho, ou seja, da comunicação do risco, pretende-se reunir algumas pistas que permitam compreender a visão que os profissionais ligados à gestão do risco, nomeadamente no âmbito das calamidades naturais têm desta disciplina de comunicação. É igualmente propósito desta dissertação aferir se a sociedade civil tem acesso a informação no que concerne a comportamentos redutores do risco no domínio da ocorrência de uma catástrofe natural, tais como um sismo ou um tornado. Neste sentido, pretende-se, portanto clarificar, em primeiro lugar, se existem, de facto, esforços de comunicação no que diz respeito à divulgação de informação sobre os riscos inerentes a um determinado fenómeno natural. E, segundo compreender o motivo pelo qual a sociedade civil portuguesa não tem um papel ativo no processo de gestão do risco: será que esta inércia se deve à falta de interesse (aliada à ignorância) da população no que concerne a temática do risco, em particular, no domínio da ocorrência de catástrofes naturais. Por fim, na presente dissertação é apresentado um guia de boas práticas para porta-vozes no domínio da comunicação do risco.

As distribuições de Lei de Potência (PL Power Laws), tais como a lei de Pareto e a lei de Zipf são distribuições estatísticas cujos tamanhos dos eventos são inversamente proporcionais à sua frequência. Estas leis de potência são caracterizadas pelas suas longas caudas. Segundo Vilfredo Pareto (1896), engenheiro, cientista, sociólogo e economista italiano, autor da Lei de Pareto, 80% das consequências advêm de 20% das causas. Segundo o mesmo, grande parte da economia mundial segue uma determinada distribuição, onde 80% da riqueza mundial é detida por 20% da população ou 80% da poluição mundial é feita por 20% dos países. Estas percentagens podem oscilar nos intervalos [75-85] e [15-25]. A mesma percentagem poderá ser aplicada à gestão de tempo, onde apenas 20% do tempo dedicado a determinado assunto produzirá cerca de 80% dos resultados obtidos. A lei de Pareto, também designada de regra 80/20, tem aplicações nas várias ciências e no mundo físico, nomeadamente na biodiversidade. O número de ocorrências de fenómenos extremos, aliados ao impacto nas redes de telecomunicações nas situações de catástrofe, no apoio imediato às populações e numa fase posterior de reconstrução, têm preocupado cada vez mais as autoridades oficiais de protecção civil e as operadoras de telecomunicações. O objectivo é o de preparar e adaptarem as suas estruturas para proporcionar uma resposta eficaz a estes episódios. Neste trabalho estuda-se o comportamento de vários fenómenos extremos (eventos críticos) e aproximam-se os dados por uma distribuição de Pareto (Lei de Pareto) ou lei de potência. No final, especula-se sobre a influência dos eventos críticos na utilização das redes móveis. É fundamental que as redes móveis estejam preparadas para lidar com as repercussões de fenómenos deste tipo.

RESUMO - Nos últimos anos, as catástrofes naturais têm sido a causa frequente de problemas de Saúde Pública; além disso representam um sério obstáculo ao desenvolvimento das comunidades atingidas, na medida em que consomem ponderáveis recursos para a mitigação dos danos sofridos. Pode-se dizer que não existe nenhum país que não esteja exposto ao risco de catástrofes naturais, tais como Sismos, Tsunamis, Erupções Vulcânicas, Movimentos de Vertentes, Ciclones Tropicais, Ondas de Frio e de Calor, Secas e Inundações, e como tal, este é um problema global emergente. Como, actualmente, é impossível prever e controlar a ocorrência destes fenómenos, as acções humanas têm de ser direccionadas para a implementação de soluções que possam mitigar e/ou prevenir o seu impacto na sociedade. A integração do lugar, do espaço e do tempo na Saúde Pública, como componentes de investigação relativas aos problemas da população, são uma ferramenta metodológica importante no auxílio do planeamento, monitorização e avaliação das acções em saúde. O que está em causa neste estudo é o pensar, o preparar e o adaptar os nossos territórios e populações a cenários de crise que podem aparecer sem aviso prévio. Este trabalho é, sobretudo, uma forma de pensar e planear o futuro numa lógica de adaptação e valorização do território, construindo referenciais de suporte à acção. Assim, a finalidade deste estudo é contribuir para melhorar/aperfeiçoar a resposta perante novas situações de catástrofe natural, através da percepção e caracterização de situações anteriores de catástrofes naturais a que a Ilha de São Miguel, nos Açores, esteve sujeita nos últimos vinte e seis anos, através da construção e análise de cartas de localização de risco, caracterização da população em risco e da avaliação dos respectivos Planos de Emergência. ---------------------- ABSTRACT - In the last years, the natural disasters have been the frequent cause of Public Health problems and additionally they represent a serious obstacle to the development of the communities affected, in so far as they consume ponderable resources to the mitigation of the damages. It is possible to be said that there is not any country that is not exposed to the risk of natural disasters such as earthquakes, tsunamis, volcanic eruptions, landslides, tropical cyclones, waves of heat and coldness, droughts and floods, and as such, this is an emerging global problem. As it is now impossible to predict and control the occurrence of these phenomena, human actions must be directed to implement solutions that can mitigate and / or prevent their impact on society. The integration of place, space and time on Public Health, as part of research on problems of the population, are an important methodological tool to aid planning, monitoring and evaluation of activities in health. The main issue in this study is to think, prepare and adapt our territories and populations to crisis scenarios that may occur without notice. This work is mainly a way of thinking and planning ahead in a logic of adapting and improving the area, building frameworks to support the action. Thus, the purpose of this study is to contribute to improve / optimize the answer for new natural disaster situations, through the perception and characterization of previous situations of natural catastrophes that the Island of São Miguel, in the Azores, has been subject in the last twenty six years, through the construction and analysis of risk maps, characterization of the population in risk and of the evaluation of the respective Plans of Emergence.

This paper describes the development and testing of a robotic capsule for search and rescue operations at sea. This capsule is able to operate autonomously or remotely controlled, is transported and deployed by a larger USV into a determined disaster area and is used to carry a life raft and inflate it close to survivors in large-scale maritime disasters. The ultimate goal of this development is to endow search and rescue teams with tools that extend their operational capability in scenarios with adverse atmospheric or maritime conditions.
