Lors du tsunami de Tohoku en 2011, des relevés de terrain sur les côtes japonaises ont montré la fragilité des structures côtières, où le plus grand brise-lames du monde (brise-lames de Kamaishi) a été fortement endommagé dû à cet événement. Dans ce doctorat, l'objectif est d'étudier l'interaction entre les brise-lames , les structures côtières les plus communes protégeant les zones urbaines et les entrées des ports, et les vagues, en particulier les tsunamis.Dans la première partie de ce travail, la transformation du tsunami en bore ondulaire dans les zones côtières est étudiée numériquement avec le code de calcul BOSZ (modèle Boussinesq). Les résultats montrent que la deuxième vague générée par le tsunami de Tohoku s'est transformée en un bore ondulaire. En revanche, la première vague n'était pas assez cambrée pour permettre une telle transformation. Les forces et les moments dus aux vagues ainsi que la contrainte normale appliquée par la base arrière du caisson sur le sol de fondation sont calculés à l'aide de deux modèles numériques différents: BOSZ et THETIS (modèle Navier-Stokes). Les résultats de BOSZ sont comparés avec THETIS pour l'interaction tsunami-structure. L'étude d'impact est réalisée à relativement grande échelle dans le but d'obtenir une première estimation des efforts d'un tsunamiPar la suite, une expérience numérique utilisant le modèle THETIS a été réalisée pour étudier les impacts du type flip-through sur des brise-lames. Ces impacts de vagues sans air emprisonné sont considérés comme le type d'impact le plus extrême dans la littérature (e.g. Cooker & Peregrine (1992), Hofland et al. (2011)). L'influence de l'inclinaison de l'interface sur la dynamique d'impact et les pressions générées sont analysées dans une configuration de brise-lames réelle. Le modèle d'onde solitaire est utilisé pour générer trois impacts caractéristiques du type flip-through: peu cambré, moyen et très cambré. Le champ de vitesses et la pression à l'intérieur de la fondation sont également étudiés dans cette partie. Les forces horizontales et verticales appliquées sur le caisson sont estimées en intégrant les distributions de pression données par THETIS.La dernière partie de ces travaux montre la stabilité des caissons de brise-lames soumis à des impacts du type flip-through, qui sont ici assimilés à un jet triangulaire (e.g. Cumberbatch (1960), Kihara et al. (2015)). Cette approche simple permet de formuler un modèle semi-analytique pour prédire le mouvement des caissons dû à ce type d'impacts. Après validation avec des simulations numériques, la méthode du jet triangulaire permet d'obtenir des informations sur les forces, la durée du mouvement et le déplacement total en fonction des caractéristiques de la vague et des dimensions du caisson du brise-lames impactéDuring the Tohoku tsunami in 2011, field surveys of the east coast of Japan showed the weakness of coastal defences, as even the world largest tsunami breakwater (Kamaishi) almost completely collapsed due to this event. In this PhD, the aim is to investigate the interaction between breakwaters, the most common offshore coastal structures protecting urban areas and harbour entries, and waves and especially tsunami waves.In the first part of the work, the generation of undular bores in the near-shore area of Sendai during the Tohoku event is numerically investigated with the numerical model BOSZ (Boussinesq-type model). It is shown that the second wave, which stroke the coast during this event, transformed into an undular bore, whereas the first wave did not due to steepness differences. Tsunami loads, moments and bearing stress applied on the offshore breakwater of the Soma Port are calculated using two models: BOSZ and THETIS (Navier-Stokes VOF model). BOSZ results are compared to THETIS for the tsunami wave-breakwater interaction. The impact study is carried out at a relatively large scale aiming to have a first estimation of tsunami efforts. Then, a numerical experiment using THETIS is carried out to investigate flip-through impacts on vertical breakwaters. This non-aerated wave impact is considered as the most severe type of impact in the literature (e.g. Cooker & Peregrine (1992), Hofland et al. (2011)) in terms of maximum pressure generated. The influence of the front interface on the impact dynamics and the pressure induced is analysed in a realistic breakwater configuration. Solitary waves are used to obtain three characteristic flip-through impacts involving least steep, medium steep and steepest wave front. The flow field and pressure inside the porous rubble mound are then investigated as well as horizontal and uplift forces applied on the breakwater caisson. The last part of this study is devoted to the stability of breakwater caissons submitted to flip-through impacts. The latter are here assimilated to water wedges (e.g. Cumberbatch (1960), Kihara et al. (2015)). This simple approach allows to formulate a semi-analytical model to predict caisson motion due to this type of impacts. After validation with numerical results, the water wedge method gives rich informations about forces, motion duration and sliding distance depending on the wave impact characteristics and breakwater caisson dimensions

Thesis (M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2012.Cataloged from PDF version of thesis.
Includes bibliographical references (p. 105-108).
Sustainable disaster recovery is increasingly understood as a comprehensive process that extends beyond physical reconstruction to include efforts to improve the affected communities' ability to adapt, respond and be more resilient in the face of future emergencies. Additionally, the success of such a complex endeavor requires overseeing agencies to act with speed and efficiency but without compromising the government's safeguards and integrity. Coordinating agencies deployed after emergencies fulfill the efficiency requirement but falter on the other two, while reconstruction through permanent government sometimes lacks speed. I postulate that Implementing Temporary Organizations (ITO) can be a solution. Due to their unique characteristics (experimentation, flexibility, limited duration, smaller size and creation by new regulation), ITOs can be an ideal vehicle for experimentation within the restrictions that regulate government action. They can also be used as laboratories for new governance practices, which once tested and adapted, can be 'absorbed' back by a permanent organization, making more resilient in the future. To explore this hypothesis, this thesis looks at Indonesia's Rehabilitation and Reconstruction Agency (BRR), an ITO in charge of the reconstruction in Aceh and Nias after the devastating tsunami of 2004 and earthquake of 2005 which gained worldwide recognition for its results in rebuilding physical infrastructure. This research looks at how the BRR approached the challenge of training local government officials: instead of traditional capacity-building programs, the BRR's approach to capacity development was the adoption of staff and the creation whole units within the Agency (staffed by locals) which were later 'transplanted' back to the regional government. I find evidence that the BRR's structure as an ITO facilitated experimentation and accelerated its teaching processes in ways not possible for a permanent government or a development agency. Many of the innovations that grew out of this environment were later institutionalized within the local and national government in Indonesia, strengthening them in the long term. These findings demonstrate ITOs are an effective way to manage disaster recovery efforts, and are even helpful in serving as laboratories to produce new knowledge and drive change in permanent organizations.

Understanding the impact of coastal forests on the propagation of rapidly advancing onshore tsunami bores is difficult due to complexity of this phenomenon and the large amount of parameters which must be considered. The research presented in the thesis focuses on understanding the protective effect of the coastal forest on the forces generated by the tsunami and its ability to reduce the propagation and velocity of the incoming tsunami bore. Concern for this method of protecting the coast from tsunamis is based on the effectiveness of the forest and its ability to withstand the impact forces caused by both the bore and the debris carried along by it. The devastation caused by the tsunami has been investigated in recent examples such as the 2011 Tohoku Tsunami in Japan and the Indian Ocean Tsunami which occurred in 2004.
This research examines the reduction of the spatial extent of the tsunami bore inundation and runup due to the presence of the coastal forest, and attempts to quantify the impact forces induced by the tsunami bores and debris impact on the structures. This research work was performed using a numerical model based on the Smoothed Particle Hydrodynamics (SPH) method which is a single-phase three-dimensional model. The simulations performed in this study were separated into three sections. The first section focused on the reduction of the extent of the tsunami inundation and the magnitude of the bore velocity by the coastal forest. This section included the analysis of the hydrodynamic forces acting on the individual trees. The second section involved the numerical modeling of some of the physical laboratory experiments performed by researchers at the University of Ottawa, in cooperation with colleagues from the Ocean, Coastal and River Engineering Lab at the National Research Council, Ottawa, in an attempt to validate the movement and impact forces of floating driftwood on a column. The final section modeled the movement and impact of floating debris traveling through a large-scale model of a coastal forest.

Les objectifs de la thèse étaient d’identifier le nombre de MTI en développement, d’évaluer prospectivement l’impact financier que produiront les traitements innovants et de rechercher de nouvelles modalités de paiement des MTI pour aider les décideurs publiques à anticiper l’impact des MTI à court et moyen terme sur le budget de l’assurance maladie. Le nombre de MTI en développement est évalué par le dénombrement des essais cliniques des MTI dans 3 bases de données internationales. Cette étude a montré le grand nombre de MTI en développement et susceptible d’arriver sur le marché. L’impact budgétaire des MTI est évalué. Des modèles de Markov ont été développés pour 3 maladies : Alzheimer, Parkinson et l’insuffisance cardiaque. Ensuite, l’impact des MTI dans 35 maladies sera estimé à l’aide des hypothèses. Cette section montre que les prix élevés des MTI seront inabordables, les payeurs ne pourront pas payer le prix de tous les MTI à l’avance. Une identification des modèles de paiement des thérapies innovantes est effectuée via une revue de la littérature. Ces modèles ont été évalués et discutés durant une réunion d’experts puis un modèle de paiement optimal pour les MTI est suggéré. Des recommandations stratégiques sont présentées pour aider les industriels et les décideurs publiques à assurer l’accès des patients aux thérapies innovantes tout en maintenant la pérennité de l’assurance maladie et évitant la failliteThe objectives of this thesis were to identify the magnitude of the ATMPs pipeline, to assess the budget impact of ATMPs and to suggest new funding models for ATMPs in order to help decision-makers to anticipate the hypothetical short and medium term budget impact of such products. The magnitude of ATMPs pipeline was evaluated by identifying the number and characteristics of ATMPs clinical trials in 3 worldwide clinical trials databases. A large number of ATMPs are in development (939 clinical trials) and may successfully reach the market. Overall, the results showed that the number of ATMPs clinical trials has been consistently growing over the past 15 years. The budget impact of ATMPs was assessed. Markov models were developed to assess the cost-effectiveness and budget impact for ATMPs using 5 efficacy scenarios in Parkinson disease, Alzheimer’s disease and heart failure. Then, an estimation of the budget impact of 35 ATMPs was conducted suggesting that an ATMP can cure all patients. We have shown in this chapter that a cost-effective ATMP may be unaffordable; payers will not be able to pay upfront the costs of all ATMPs. The traditional funding models may not be adaptable for ATMPs. The proposed funding models for innovative high-cost therapies were identified through a literature review, discussed during a consensus meeting and an optimal funding model for ATMPs was recommended.Finally, health policy recommendations for the stakeholders – patients, physicians, payers and manufacturers – are presented. These recommendations aim to help to ensure patient access to innovation while maintaining the sustainability of healthcare system

Повний текст джерелаАнотація:
This paper quantifies and analyzes the economic impact of the Great Tohoku Earthquake and tsunami on the Japanese electricity industry using alternative event study methodology. The data set includes daily stock prices of 11 publicly traded electricity companies. This paper investigates the changes in systematic risk, abnormal returns (ARs), and cumulative abnormal returns (CARs) before and after the natural disaster. In addition, I compare the movement of the stock price in the electricity industry with other indices in Japan to investigate the aggregate level impact on the Japanese economy. By examining the economic impact of the earthquake, this paper provides a visual and a numerical representation of the change in investors’ views on the electricity industry. The results showed no statistically significant changes in ARs in the immediate aftermath of the disaster. On the other hand, statistically significant changes in CARs were found for all 11 electricity companies over an extended period following the disaster. Furthermore, there was a statistically significant increase in systematic risk, especially in the nuclear-committed firms. Although the electricity industry was negatively affected, daily stock prices and CARs show that other industries were not as severely affected. These results provide insight to the global economic and the political implication of the disaster.

Tsunami action had resulted in negative impacts in many ways, it had resulted in great changes to coastal areas, especially in terms of physical change to the coastal landscape, affected on economy, loss of life and physical damage to property. After the devastation, hotel bookings in the island were dropped, people have lost their jobs and some small-scale tourism businesses have got the hardest time as well. Some lifestyle entrepreneurs felt hopeless and have given up on doing business, which resulted to their businesses had to be closed because they were unable to access financial resources and did not have budget to restart their businesses again. Some might take longer time to rehabilitate their firms due to various limitations and conditions. While some have to fight back and develop their firms by turning crisis into opportunity and taking advantage of the crisis. This research is made in order to study and examine the impacts of and the recovery to the 2004 December tsunami disaster in Phuket, especially to small tourism businesses in Karon beach, which will be described through a disaster management model. The goal of this research is to study how the tsunami has affected on small firms and how they performed in order to rehabilitate their businesses, and even how they have been working and cooperating with the local government to draw back tourists to the destination.

The main objective of this study was to investigate and quantify the impact of extreme hydrodynamic forces, similar to those generated by tsunami-induced inundation, on structural elements. As part of a comprehensive experimental program and analytical study, pressures, base shear forces, and base overturning moments generated by hydraulic bores on structural models of various shapes were studied. In addition, the impact force induced by waterborne wooden debris of different shapes and masses on the structural models was also investigated. Two structural models, one with circular and the other with square cross-section, were installed individually downstream of a dam-break wave in a high-discharge flume. Three impounding water heights (550, 850 and 1150 mm) were used to produce dam-break waves, which have been shown to be analogous to tsunami-induced coastal inundation in the form of highly turbulent hydraulic bores. Time-history responses of the structural models were recorded, including: pressures, base shear forces, base overturning moments, lateral displacements, and accelerations. In addition, the flow depth-time histories were recorded at various locations along the length of the flume. Regular and high-speed video cameras were used to monitor the bore-structure interaction. The effect of initial flume bed condition (“wet” or “dry” bed) on the forces and pressures exerted on the structural models were also investigated. Moreover, the vertical distribution of pressure around the models was captured. Simple low-height walls with various geometries were installed upstream from the structural models to investigate their efficiency as tsunami mitigation measures. The experimentally recorded data were compared with those estimated from currently available formulations.
The results and analysis of the simulated tsunami-induced bore presented in this study will be of significant use to better estimate forces exerted on structures by tsunami-induced turbulent bores. It is expected that this work will contribute to the new ASCE7 Chapter 6 - Tsunami Loads and Effects in which two of this author’s academic supervisors, Drs. Ioan Nistor and Dan Palermo, are members.

Cette thèse traite de la modélisation des tsunamis, des grandes échelles de propagation aux impacts sur desstructures côtières. Un inventaire des phénomènes physiques associés est établi et des modèles adéquats sontprésentés. Une étude numérique avec le modèle de Saint-Venant est effectuée avec le développement d’uneméthode de raffinement de maillage à seuil automatique. La simplicité et les performances de l’approche sontdémontrées. Pour améliorer la précision des prévisions, un système original approchant le modèle Serre-Green-Nahgdi est investigué. Une méthode pour prendre en compte la dissipation d’énergie au déferlement estproposée. Ce modèle permet d’envisager la modélisation fine de la propagation et de l’arrivée à la côte destsunamis dispersifs et non linéaires en des temps de calcul acceptables. Les différents types d’impact sur desstructures sont modélisés grâce à un modèle diphasique compressible permettant de considérer les écoulementsà phases séparées et les milieux aérés. Pour envisager une résolution à tous les régimes, des schémas TousMach sont investigués. Un schéma Tous Mach à variation totale limitée est proposé. Grâce à cette approche,des impacts incompressibles et compressibles sont investigués avec le même modèle. Les impactsd’écoulements aérés induisent des pressions moins élevées mais sur des temps plus longs que leurshomologues en phases pures. Bien que le schéma Tous Mach proposé soit moins sujet aux oscillationsnumériques que les préconditionnements classiques de la littérature, des oscillations non physiques à basnombre de Mach sont mises en évidence sur certains cas tests. Pour finir, une méthode de couplage entremodèles de propagation et d’impact est proposée, afin de pouvoir simuler un tsunami finement avec desmodèles appropriés à chacune de ces phasesThis thesis deals with tsunami modeling, from the large propagation scales to impacts on coastal structures. Aninventory of the associated physical phenomena is given and some adequat models are presented. A numericalstudy is carried out with the Saint-Venant model with the devellopment of an automatic refinment adaptivemesh method. The resolution efficiency and simplicity is justified. To increase the accuracy forecasts, anoriginal system which approximates the Serre-Green-Naghdi model is investigated. A breaking wave methodassociated with this model is proposed. This dissipative model allows thinking about accurate dispersive nonlinear tsunamis simulations up to the coast. Several wave impacts on stuctures are investigated with a generaltwo-phase model allowing separate phases as well as aerated impact studies. The all Mach regime numericaldifficulties are investigated. A new all Mach scheme with limited total variation bound is proposed. Thanks tothis approach, incompressible and compressible impacts are investigated with the same model. Aerated impactsare shown to give smaller impact pressure but on longer time than pure fluid impacts. In spite that the all Machscheme proposed reduces the numerical oscillations of classical literature preconditionning, some unphysicaloscillations are highlighted on some test cases. At the end, a coupling method is proposed in order to accuratlymodel the propagation and the impact of a tsunami with appropriated models for each phases

This report focuses on using the Papathoma Tsunami Vulnerability Assessment Model (PTVA) to demonstrate the vulnerability of Cayucos to a 500-year tsunami, and using the results to inform specific planning recommendations. By modeling inundation with GIS and analyzing building attributes via the PTVA model, this study has gone beyond any previous vulnerability assessments of Cayucos. Findings include: delineation of the most vulnerable areas, estimates of numbers of lost civic buildings, commercial buildings and houses, as well as estimates of people displaced from tsunami damaged homes. The report goes on to discuss what mitigation measures are in place and what further specific steps could be taken to ensure the long term sustainability of the town and help reduce future tsunami losses.
Cayucos is a small coastal town in San Luis Obispo County, California; popular with tourists and locals for its beach, pier, and downtown. Intense coastal development and low lying topography makes Cayucos among the most tsunami vulnerable communities in the county. Many civic and economically important buildings, as well as homes, are within the 500-year tsunami inundation area.
In the absence of fully developed, and accessible assessment tools like FEMA’s HAZUS tsunami program; local planners have had only basic information to assess the community’s tsunami vulnerability. The Papathoma Tsunami Vulnerability Assessment Model (PTVA) is a method that uses available tsunami runup estimations and field data collection to produce a detailed assessment of individual building survivability and overall community vulnerability.

To build a tsunami-resilient coastal community it is fundamental to understand the characteristics of past tsunami patterns and likely impact of possible future events. The MOST model (Method of Splitting Tsunami) and ComMIT (Community Model Interface for Tsunami) were used to model patterns of water levels, wave speed and direction, and inundation distances resulting from the 2004 Indian Ocean tsunami on the Khao Lak coast of Thailand. The model of the 2004 tsunami was calibrated against estimates of water depths made along the coast in early 2005; an M, = 9.3 earthquake in the model was found to best match observations. The model was verified against a variety of other evidence, including digital photographs and video clips taken on the day of the tsunami, mainly from two sites along the Khao Lak coast at Nang Thong and Bang Niang beaches, together with aerial surveys and a tide-gauge record. The timing and extent of water recession prior to the arrival of the first wave, the heights and number of the subsequent waves, and the inundation distances corresponded well providing confidence in the application of the MOST model to this coastal region. Historical evidence suggest that tsunami of the magnitude of 2004 are rare (200-700 y) so for mitigation planning in the Khao Lak area a smaller tsunami genic-earthquake (M; =8.9) was chosen (l00-500 y). Sensitivity to the choice of M, was also considered. The tsunami from such an event is similar in its character to the 2004 event, less extreme but still highly destructive, reaching the Khao Lak coast in ~ 2 h 15 min, and preceded by receding water levels. The first wave (5.0-6.5 m high) arrives 2h 25 min after the earthquake travelling at 6-8 mls at the coastline.

Повний текст джерелаАнотація:
Crabs of the genus Dotilla are ecologically important members of intertidal sandy shore communities. Exposed sandy shores represent one of the main habitat types along the coast of the Laem Son National Park in Thailand, and Dotilla sp. is the dominant macrofaunal species on these beaches, occurring in immense numbers. Despite their importance as a key member of the faunal community on these beaches, little is known about the ecology of Dotilla crabs in the Laem Son. Taxonomic investigations identified the Dotilla crabs present on the exposed oceanic beaches in the Laem Son to be D. intermedia. This represents the first time that D. intermedia has been recorded from Thailand. Dotilla intermedia inhabits a very well defined zone on the sandy beaches, and the factors underlying these zonation patterns were examined. The gradient of the beach was correlated to the height at which the boundaries of the Dotilla zone occurred, with physical factors associated with the beach gradient driving the distribution of D. intermedia on the beach. The upper limit of the Dotilla zone was controlled by the total water content of the sediment, with D. intermedia absent from areas with less than 15% total water content. Tidal influences defined the lower boundary of the Dotilla zone, with crabs requiring an area with a minimum exposure time between tidal immersions of 4-5 hours to feed on the sediment. Within the Dotilla zone, size segregation was observed; larger crabs occurred higher on the shore, and small crabs lower down. The sandy shores of the Laem Son were heavily impacted by the tsunami of 26th December 2004, which effectively destroyed the populations of D. intermedia on the beaches. However, by April 2005 D. intermedia was present again on the beaches. A temporal population genetic study was undertaken to investigate the impact of extinction and recolonisation on the genetic variation of a population. Genetic variation in mtDNA markers was found to decrease over time, matching the predictions of mathematical models concerning the effect of bottlenecking events on genetic diversity within populations. The impact of the tsunami on D. intermedia is discussed further in light of the ecological and molecular data produced in this thesis.

En tant qu'événement parmi les plus puissants de l'histoire éruptive récente de Lombok, les matériaux volcaniques expulsés par le volcan Samalas en 1257 couvrent toute l'île de Lombok et sont largement répandus dans sa partie est. Près de 800 ans après l'éruption, l'impact géomorphologique de cette éruption sur l'île reste inconnu, alors que ses conséquences climatiques et sociétales globales sont désomais mieux comprises. Une combinaison des informations stratigraphiques, des topographies actuelles, des mesures géophysiques, des sources écrites locales, analyse de laboratoire et informatique ont été utilisées pour obtenir des informations détaillées sur les impacts géomorphologiques de l'éruption du volcan Samalas sur la zone côtière le long du détroit d' Alas, Nusa Tenggara Ouest, Indonésie. Cette étude fournit de nouvelles informations relatives à l'impact géomorphologique d'une éruption volcanique majeure dans des zones côtières, dans ce cas-ci, dans la partie est de Lombok, ainsi que sur la côte ouest de Sumbawa. En premier lieu, les résultats de l'étude montrent que le paysage de la partie est de Lombok est encore évolué jusqu'à présent. Le volume de matière volcanique de l'éruption des Samalas reste à environ 14% du volume initial. Deuxièmement, la découverte de Babad Suwung fournit une description supplémentaire de l'éruption des Samalas sur l'île de Sumbawa et pourraient être la plus ancienne observation visuelle de déferlantes pyroclastiques après celles de Pline Ie Jeune en 79 pour le Vésuve. Enfin, l'éruption du volcan Samalas en 1257 a prouvé avoir déclenché un tsunami mineur qui a frappé l'île de Belang, sur la côte ouest de SumbawaAs the most powerful event in Lombok’s recent eruptive history, volcanic materials thatwere expelled by the Samalas volcano in 1257 CE covered the entire of Lombok Islandand are widespread in its eastern part. Almost 800 years after the eruption, the geomorphological impact of this eruption on the island of Lombok remains unknown,whereas its overall climatic and societal consequences are now better understood. Acombination of stratigraphic information, present-day topography, geophysical measurement with two-dimensional resistivity profiling technique, local written sources,as well as laboratory and computational analysis, were used to obtain detailed information concerning geomorphic impacts of the 1257 CE eruption of Samalas volcano on the coastal area along the Alas Strait in West Nusa Tenggara Province, Indonesia. This study provides new information related to the geomorphic impact of amajor eruption volcanic in coastal areas, in this case, on the eastern part of Lombok and the western coast of Sumbawa. In the first place, the study result shows that since the 1257 CE eruption, the landscape on the eastern part of Lombok is still evolved untilthe present time. The volume of the 1257 CE volcanic material remains about 14% from the initial volume. Secondly, the discovery of Babad Suwung provides additional explanation of Samalas eruption and may become the oldest visual observation of pyroclastic surges and volcanic fallout, following those by Pliny the Younger in 79 CE. Finally, the 1257 CE eruption of Samalas volcano has proven triggered a minor tsunami that hit Belang Island, on the west coast of Sumbawa

Les déstabilisation de flancs sont un phénomène destructeur capable d'affecter un volcan quel que soit son contexte géodynamique. Dans cette thèse, le cas d'un épisode de déstabilisation de flanc est étudié pour le volcan sous-marin Kick'em Jenny. L'objectif primordial est de pouvoir appréhender le comportement dynamique de l'écoulement généré par la déstabilisation d'un flanc du proto-édifice. Pour ce faire, une étude du dépôt considéré comme étant issu de cet épisode de destruction est présentée afin d'évaluer le volume mobilisé. Cette déstabilisation de flanc est simulée à l'aide du modèle VolcFlow, basé sur une approche eulérienne de la résolution des équations de St-Venant moyennées sur l'épaisseur de l'écoulement. Deux modèles rhéologiques sont testés afin d'estimer lequel est plus à même de reproduire le comportement dynamique de l'écoulement et la mise en place du dépôt dans sa position finale. L'effet tsunamogène local (i. E. à la source) de cet épisode de déstabilisation de flanc est simulé l'aide de VolcFlow et de TOPICS (code de génération de caractéristiques de la perturbation de la surface libre à partir des spécificités de la déstabilisation). Enfin l'effet tsunamogène régional, lié à la propagation du tsunami dans le Bassin de Grenade est évalué à partir de simulations effectuées à l'aide de FUNWAVE (modèle propagation de tsunami) en considérant un modèle de propagation de type BoussinesqFlank collapses are destructive phenomena affecting volcanoes no matter their geodynamical context. In this thesis, we focus on the case of a flank collapse episode that occured at Kick'em Jenny submarine volcano. The main goal of this thesis is to assess the dynamical behaviour of the flow generated by the flank collapse episode at the proto-edifice. To do so, we first estimate volume involved in the collapse. The collapse event is simulated using VolcFlow, a model based on depth-averaged approximation of the St-Venant equations. Two rheological models are tested so that we can evaluate which one is most appropriate to reproduce the dynamical behaviour of the flow and the deposit features. Tsunamigenic effect at the source (local effect) is investigated by simulation tests using both VolcFlow and TOPICS (code providing tsunami source parameters from collapse characteristics). At last the regional tsunamigenic effect due to wave propagation towards the neighbouring islands is assessed using FUNWAVE, a Boussinesq-based model of wave propagation

El 28 de octubre de 1746, un gran sismo asoló la ciudad de Lima y trajo como consecuencia
un enorme tsunami que arrasó el puerto del Callao desde sus cimientos. Una catástrofe
marítima similar ocurrió en 1687, cuando otro maremoto golpeó las costas de la capital
virreinal a consecuencia del sismo de la madrugada del 20 de octubre. En esta ocasión, y a
diferencia de lo acontecido en 1746, las murallas sí sirvieron de protección para que el mar no
destruyese todo el presidio. Frente a los azotes de la naturaleza, el gobierno virreinal aplicó una
serie de medidas para el control de los estragos, las cuales variaron de acuerdo a la gestión de
cada autoridad. La presente tesis, compara la acción política de la casa de Austria frente a la de
los Borbones en el Perú virreinal ante un mismo hecho: la crisis económica y social causada por
un tsunami y el concepto de prevención ante este. Tal acontecimiento, en medio de diversos
contextos culturales, influía en la gestión gubernamental, desarrollándose un ejercicio y
respuesta en torno al rol integrador del Mar del Sur. Así, el miedo a la amenaza extranjera, la
piedad barroca del siglo XVII, el desarrollo del pensamiento científico y los primeros destellos
de la Ilustración, a inicios del siglo XVIII, fueron factores que configuraron las distintas
directrices seguidas por los virreyes en torno a la aplicación de políticas preventivas en Perú y
Chile, territorios integrados en un mismo espacio por la naturaleza. Importantes investigadores
han estudiado a los sismos, desde una perspectiva social, económica y cultural, como ejes
centrales de análisis históricos medioambientales, relegando los tsunamis a ser considerados
solo como fenómenos tangenciales; no obstante, esta tesis otorga una mirada central a este
desastre natural, debido a que la historia ha revelado su gran poder de destrucción en la
sociedad colonial, acontecimientos que por mucho tiempo han sido ignorados.Tesis

Tesis para optar al grado de Magíster en Geografía con mención organización urbano-regionalEste estudio analiza la distribución espacial del impacto recibido en la vivienda, así como las áreas intervenidas por parte del Estado tras el terremoto y tsunami del 27 de febrero de 2010. Su propósito es definir y analizar los patrones de distribución territorial de la gestión del Estado en la Región del Biobío, proceso que hasta agosto de 2014 aun no finaliza. La metodología involucró el análisis espacial de las 54 comunas de la Región del Biobío afectadas por el sismo de acuerdo a criterios de diferenciación socioespacial. Se trabajó sobre la base de tres variables presuntamente asociadas pero independientes entre sí: 1) impacto en la vivienda, según el tipo de daño recibido, 2) número de familias organizadas en comités de viviendas, y 3) cobertura de la gestión del Estado en materia de reconstrucción, según la información sobre viviendas reconstruidas. Como primer resultado, se obtuvo una matriz general de datos para las 54 comunas de la región, a partir de la información sobre viviendas afectadas, destruidas y reconstruidas, así como también de la participación social de la población damnificada. De este modo, a través del análisis espacial se identificaron disociaciones territoriales entre las zonas con alto impacto con respecto a la direccionalidad de las soluciones otorgadas por el Estado. Las grandes urbes de la región, aparecen como las zonas menos afectadas, pero mayormente asistidas. Por el contrario, las comunas de menor tamaño expresan un mayor impacto pero una baja asistencia por parte del Estado. En estas tendencias, la participación de la sociedad civil ha resultado ser clave en comunas que expresaron una reconstrucción eficiente. Por otro lado, si el proceso de reconstrucción se hubiese intentado direccionar tomando en cuenta el valor porcentual de viviendas destruidas, las zonas de mayor atención debieron haber sido orientadas hacia la macrozona de la zona norte de la región y la pre-Cordillera de Los Andes, de norte a sur. A partir de los resultados expuestos es posible señalar la necesidad de reforzar aún más los programas dirigidos e implementados por el Estado que propendan a fortalecer la organización social, así como considerar el desarrollo equitativo de ciudades, tanto en el contexto de grandes centros metropolitanos, como de localidades urbanas secundarias. Se espera que los resultados del presente estudio, constituyan un diagnóstico útil para la sustentación de programas, proyectos y políticas diferenciadas en virtud a las respuestas derivadas del proceso de reconstrucción, el que aun no finaliza.

The research finding of Chen-Min Hsu shows that the U.S. sub-prime mortgage crisis in the first half of 2008 was one of the reasons causing oil and raw material index price to rise and subsequent international financial tsunami which resulted in credit contraction, declining demand of commodity market, and insufficient consumer confidence. Under the conditions of global oil price increase, the exhaustion of energy resources, and the global warming, all foci are on energy. The price of energy has affected the global economic growth and attracts investors’ money. This study uses five energy funds issued in Taiwan to analyze their Returns, Sharpe index, Treynor index. In addition, this study uses three Var evaluation methods,namely Variance-Covariance Approach , Historical Simulation , and Monte Carlo Simulation . Research finding show that the performances of Investec GSF Glbl Energy C Inc Grs USD are best which also associate with higher risk. Moreover, this research divides the whole period into before, during, and after the finance crisis periods to study the performance and risk. Research findings show that before the crisis period （Jan.1, 2005-DEC.31,2006）, the performance of BGF New Energy C2 USD are best with lower risk in favor of investors. During the crisis period（Jan.1, 2007-DEC.31,2008）, the performance and risk are the worst with low return and high risk. After the crisis（Jan.1, 2009-DEC.31,2010）, the performance of Investec GSF Glbl Energy C Inc Grs USD are best which shows the fluctuation of energy stock is the highest and can easier be affected by the stock. Based on the above findings, we think investors could use the characteristics of taiwan’s energy performance and risk, the research period, different investment objectives, and different research methods to get research results closer to the realty. Theoretically, performance and risk show positive correlations. But investors could use the research finding of this study to pursue higher performance and lower risk investment so investor could pursue energy fund in a higher oil price environment.

The Indian Ocean experienced a devastating Asian tsunami damaged in the morning of 26th December 2004. This study uses a market-adjusted returns model of event study to analyze abnormal returns in Thailand’s tourism industry. The study differs from other pervious studies of market reactions to unanticipated in cross-country. We also investigate reaction on tourism stock market after Asian tsunami attack. Taiwan, Hong Kong, New Zealand and Australia from June 2004 to March 2005. In addition, this research compares difference on the abnormal returns in tourism and leisure, transportation and logistics, insurance, construction materials and construction development industries in Thailand from June 2004 to March 2005. We examine the stock market reaction for 135 days ago and draw out four day ago and 15 days later on the Asian tsunami happened. The result shows partial significant negative stock abnormal for tourism and leisure industry in Thailand. On the other hand, there are partial significant positive stock returns in the construction development and construction materials industries after tsunami attacked. There is no significant level to stand for the critical influence to Taiwan, Hong Kong, New Zealand and Australia.

With the number of wind power units (WPUs) on the rise worldwide, it is inevitable that some of these would be exposed to natural disasters like tsunamis and it will become a necessity to consider their effects in the design process of WPUs. This study initially attempts to quantify the forces acting on an existing WPU due to a tsunami bore impact. Surge and bore heights of 2m, 5m and 10m are used to compute the forces using the commercially available full 3D Navier Stokes equation solver FLOW3D. The applicability of FLOW3D to solve these types of problems is examined by comparing results obtained from the numerical simulations to those determined by small scale laboratory experiments. The simulated tsunami forces on the WPU are input into a simplified numerical structural model of the WPU to determine its dynamic response. The tsunami force is also used to obtain base excitation which when applied on
the WPU would be equivalent dynamically to the tsunami forces acting on it. This base excitation is useful to obtain the response of the WPU experimentally, the setup for which is available at University of California, San Diego's (UCSD) Large High Performance Outdoor Shake Table (LHPOST). The facility allows full scale
experimental setup capable of subjecting a 65kW Nordtank wind turbine to random base excitations. A stress analysis of turbine tower cross section is performed in order to assess the structural integrity of the WPU. It has been determined that the WPU is unsafe for bore/surge heights above 5 m. It has also been postulated that the structural responses
could be considerable in case of the taller multi megawatt wind power units of present day.

The research used five GARCH models and six residual distribution functions to study the volatility forecasts of Taiwan, Shanghai, and Hong Kong stock price indexes during the financial crisis. The effects of error distribution function and trading volume on the volatility forecasting are studied in this research. The squared returns of five minutes intraday data were used as the volatility proxy variables. The Poon and Granger (2003) and Brownlees (2011) rolling window estimation structure method is used as the estimation method of this study. Following Patton (2011), the loss functions are estimated by a combination of imperfect fluctuations in the proxy variables and the robust loss function MSE and QLIKE. QLIKE is not affected by the extreme value of a tail. Therefore, the main loss function selected in this research was mainly from QLIKE with MSE function as the supplement. The paired comparison method and multi-model comparison method were used in the comparisons of loss functions, in which the former employed the Giacomini and White (2006) test (G-W test) and the latter employed the model confidence set (MCS) by Hansen et al. (2011). In the paired comparison between skewed residual distribution and standard residual distribution of GARCH models, both with and without the volume time series in the model, the error distribution functions must be standard when the volatility forecasting performances Taiwan and Hong Kong stock markets are statistically significantly better. Therefore, when using different GARCH models for volatility prediction, it is necessary to consider the variations in different error distribution functions during the global financial crisis. In the case of Taiwan stock market models with trading volume in the skewed distribution, except the EGARCH model, the results were all out of the Model Confidence Set. Different from Taiwan, in the case of Shanghai stock market models with trading volume in the skewed distribution, except the EGARCH model, the results were all in Model Confidence Set. Except EGARCH model, adding trading volume in the models could improve the volatility forecasting in the Hong Kong stock market. Therefore, in the comparison of the volatility predictions of skewed and standard error distributions, there is no consistent conclusion that skewed distribution is better in prediction. The GARCH-type models with trading volume have poor performance of out-of-sample volatility forecasting in Taiwan and Shanghai stock market. However, models with trading volume can improve the volatility forecasting in Hong Kong stock market.

The structure of the global financial system has changed significantly in the past decade. Banks create credit liquidity through securitization, and also increase bank's risk simultaneously. As credit defaults rising continuously, the financial corporation face the financial crisis causes from subprime mortgage collapse. Such a vicious circle phenomenon affects not only the financial system, but also influence the industries and global economy. The influence of this financial crisis occurs so fast and tremendous that is called financial tsunami by scholars. This dissertation adopts the economy data of global countries from the database of IMF and World Bank. The cluster analysis are used to classify global countries into several groups according to their economical status, geographic location, and country scale. After clustering, the ANOVA and the multiple comparison procedures are followed to compare the influence level of the financial tsunami with respect to the groups of countries. Several results are described below: Firstly, the global economic growth rate of 2009 is worse than that of 2008. Secondly, annual inflation rate of 2009 is significantly lower than that of 2008. Thirdly, economic growth rate of the countries with high export proportion has greater adverse effect from the financial tsunami. Fourthly, the countries with high import proportion have higher inflation rate. Fifthly, the economic growth rate of the countries with higher proportion of external debt have worse effect than the countries with lower external debt proportion. Sixthly, the influences of financial tsunami are not related with the population and scale of the country.

March 12, 2007 New Century Financial Corporation declared bankruptcy. At that time U.S. sub-prime mortgage crisis was brewing. This caused financial tsunami effects throughout the world with devastating economic consequences such as collapse of consumer/investor confidence which resulted in severe global economic downturn. It also dragged Taiwan into deep recession. The stock market dropped steeply. Personal and corporate wealth sharply slumped. Being a representative of developmental states, government used to play an essential role and adapted all the policy with emphasized in certain industry. For example; machine tool industry, the semiconductor industry, TFT-LCD panel industry. At the perspective of industry clusters, this study explores how machinery and equipment industry in Taiwan was affected by financial tsunami, which includes machine tool industry, the semiconductor industry, and TFT-LCD panel industry. The subjects were categorized into two groups, traditional equipment and electronic equipment. These two groups were researched respectively how they were affected by the financial tsunami and how they react to the crisis with views of market concentration, customer concentration, technology intensity, and product line breadth.

The human history has witnessed and record several panic phenomena for the world’s economy, including the economy downturn of U.S. in 1930s, the Asian financial crisis caused by Japan’s bubbling economy and Thailand’s financial crisis in late 1980s, and the global crisis caused by U.S. subprime lending crisis in 2008 and all the financial tsunami have brought bankruptcy and closure of financial institutes or enterprises, global economy downturn, national property shrinkage, lay-offs, reduced payment and unemployment etc. The global financial crisis was unavoidable and every nation has taken relevant measures after a tense nerve. The advanced development of science & technology has resulted in gradual dissolved geographic territory—a “global village” and the threat of one nation can be spread to other nations rapidly for a more widely-spread and deeper impact. The long-term neglect of economy security to global development has deepened the threat and people should highly focus on the problem after a globalization trend. The “open-up and reform” policy mainland China adopted since 1980s has promoted the economic development rapidly and created a large-scale of wealth for the nation and its people. The mainland has adopted other policies for a new round of macro-economic control and increasing domestic demand to maintain economic growth rate during the worldwide financial crisis and thus made China the hope for saving the global economy. The business opportunity from increasing domestic demand is a chance for Taiwan—mainland’s frequently-cooperated partner on economy and trade. The mainland and Taiwan experienced tangle due to political reasons during the past and the relationship has been improved significantly since the open policy. Since both governments planned promoting cross-strait cooperation and the two parties signed Economic Cooperation Framework Agreement (ECFA) for a closer relationship on economy and trade. The complements from the cross-strait partners can create a new economic format in future.

The 2008 financial tsunami shook the global economic landscape. This study set out to determine the impact – if any – the tsunami had on the return volatility of hedge funds, and how this impacts hedge fund risk control and investment decisions, as this had yet to be determined within the academic and business fields. This was done through applying the methodology of autoregressive conditional heteroscedasticity (ARCH) and generalized ARCH (GARCH) models. In order to determine whether the specific event of the financial tsunami has had a significant prolonged impact on the volatility of the data, a dummy variable was set to distinguish the data by the event. Before the event, the dummy variable was set to be zero; after the event, the dummy variable was set to be one. Of the six Hedge Fund Research (HFR) indices’ return volatilities investigated, three (Equity Market Neutral, Relative Value Arbitrage, and Absolute Return) were found to have increased after the financial tsunami, one (Global Hedge Fund) was found to have the decreased, and two (Equity Hedge and Macro) were found to have not been significantly impacted by the tsunami. For those return volatilities that were impacted by the tsunami, the study determined that the model to be used should be the GARCH model which includes the dummy variable, in order to allow hedge fund managers and investors to more precisely make risk-control limitation allocations and conduct return-risk trade-off judgements. For the Equity Hedge and Macro indices, the original GARCH model should be used.

Financial crisis 2008, also called “Financial Tsunami”, broke in the US and other Western and Asia economies. No doubt, the tremendous financial crisis shock caused not only global economic depression but also result in negative effect in economic development in particular countries. This crisis is more serious than previous experiences, and may take even longer. Many economic forecasts seem unclear for the present economic disaster. It is obviously to see many emerging markets, such as Taiwan and Southeast Asian countries, will continue to grow slower. Since many Taiwan’s manufacturers have switched their production bases to mainland China, they suffer great decline both on export orders and industry productivity. It reflected significant impact especially on the export growth in overall; the lacking of domestic consumption and the lower demand for exports. With so many economic uncertainties, it is important to discuss how we can take reform efforts for reinforcing business sustainability, and which policy should be adopted in order to expand highly profitable businesses. The study uses Sea Freight Forwarding as an example. It explores the following issues through interviewing with some managers of Taiwan’s freight forwarding industries: 1. The operational difficulties under current market situations 2. What kinds of risk management strategies can be adopted at present stage 3. What kinds of customer service can be provided 4. The guide performing on-the-job training to their employees 5. What are the effective strategies in marketing and customer relationship management This study also discusses the practices freight forwarding businesses and their challenges. The result of this study aims to provide reference for ocean freight forwarding businesses while working out their operational strategies in order to overcome global economic depression during these years. Keywords: Financial crisis, ocean freight forwarders, business strategies.

The financial tsunami, extended from the financial to the essential aspect, swept the whole world in 2008. With consumption grinding to a halt and a downturn in world trade, the export industry in Taiwan has borne the brunt of these events, causing a recession, which has said to be the toughest ordeal of the decade in Taiwan industry. Currently, the “quality” instead of the “quantity” of employees has became the main concern for corporate. Therefore, making employees the company’s investment—and not liabilities—puts managers’ wistom to a test. It has been found in relevant literature that the key to corporate competition and corporate value resides in intellectual capital, with human capital being the primary and crucial component. Many companies have turned to lay-off policy during this financial tsunami. And how will intellectual capital change along with the shift in human capital? The executives will have to use a model to measure intellectual capital efficiency as a referrance for managerial decisions when reincorporating the company’s inner resources to make duely adjustments and develop its competitive niche. Intellectual capital, underlying competitive advantage for corporations, accumulates over time. Great changes cannot be expected within a short period of time. But as corporates continue to trim their workforce in the face of financial tsunami, the change in intellectual capital has been more than ever. That is why this study uses data envelopment analysis as method for evaluating corporate intellectual capital and efficiency analysis. We did a case study of a company of its monthly data between January 2007 and September 2009, a total of 33 months, so as to hurry grasp the shift and modification of corporate competitiveness towards sustainable management in the course of time.

This research focuses the impact of exchange rate volatility on Taiwan’s exports before and after financial tsunami. Using GARCH model the volatility of exchange rate is estimated in the beginning, following by export equation for further calculation. We use monthly data covers from JAN., 2005 to FEB., 2011 in this study. Taiwan is a county which highly depend on export trading and tend to be affected by sub-prime mortgage crisis. The empirical study shows that exchange rate volatilities do have effect on Taiwan’s exports.

The study conducts a bullwhip effect analysis on Taiwan’s semiconductor industry. We divide the semiconductor industry into three sub-industries namely: IC design and wafer foundries (IC), testing and packing (PT), and electronic component (EP) to present upper-stream, middle -stream, and down-stream in semiconductor industry respectively. The examining period is from January of 2006 to December of 2010. In the descriptive statistic analysis, we find that the coefficient of variation of IC is greater than PT’s, and PT’s coefficient of variation is greater than EP’s. The empirical results are shown as following: (1) the difference of the logarithm in the series is stationary when the unit root test is conducted. (2) the minimum value of Akaike Information Criterion (AIC) is found at the lag 8. (3) the high value of R-squared, implying highly explanatory powers among three variables(with lag terms) from the Vector Autoregressive Regression (VAR) analysis. (4) the causality is found from down-stream industry to upper-stream industry in the Granger Causality Test. (5) from Impulse Response Function Analysis (IRF): the response of design and wafer foundries to the shocked in electronic component is greater than the response of electronic component to the shocked in design and wafer foundries. The study finds a significant bull-effect in Taiwan’s semiconductor industry. Since large portion of Taiwan industrial products is from electronic related industries such as semiconductor, any shock from consumer electronic product could have large impacts on semiconductor, and Taiwan economy is suffered deeply. Therefore the diversification of Taiwan industrial structure is needed to reduce the loss from the immediate shock such as the Financial Tsunami.

Tookoonooka and Talundilly are two large meteorite impact structures buried in the sedimentary rocks of central Australia, and are among the largest impact structures known on Earth. They are shown to be a rare example of an ancient marine impact event and are also an extremely rare terrestrial example of a probable binary impact event. A preserved marine impact ejecta horizon, interpreted to span a vast area of the continent and corresponding to the extent of a Cretaceous epicontinental sea, is used to biostratigraphically constrain the impact age to the Barremian-Aptian boundary (125 +/- 1 Ma) in the Lower Cretaceous. Evidence is presented that the Wyandra Sandstone Member petroleum reservoir overlying the horizon is, in part, a binary impact tsunamiite. Analyses of drill core, subsurface drilling data, and geological outcrops over >805,000 km² show that the base of the Wyandra Sandstone Member is an impact horizon: a widespread scour surface that is attributed to impact-related excavation and tsunami scour mechanisms. The impact horizon is underlain by seismites and overlain by very poorly sorted sediment with highly polymictic exotic clasts, imbricated pebbles, and intraformational cobble rip-up clasts. Exotic clasts are predominantly interpreted as impactoclasts, and include complex accretionary and armoured impactoclasts of vapour plume origin, shock-metamorphosed lithic fragments, and altered melt impactoclasts. Some lithic fragments resemble basement lithologies from the Tookoonooka and Talundilly target rock sequences. The stratigraphy of the Wyandra Sandstone Member contains elements characteristic of impact tsunami deposition including ejecta entrained in high flow regime bedforms, pebble to boulder-sized clasts, >16m thick beds, and cyclic sedimentation of tsunami couplets, across five depositional realms. These elements are in stark contrast to the persistently low-energy nature of the ambient sedimentation and overlying quiescent marine shales, but are consistent with the intense seismicity, high energy seiche action and rapid deposition expected from a marine impact in a mostly enclosed basin. A dual impact source is indicated, based on sediment distribution patterns in combination with the proximity of the impact structures in age and location. The Wyandra Sandstone Member records both marine impact depositional processes as well as the waning of the event; the upper part of the Wyandra returns to background depositional energies and intense bioturbation and is conformably overlain by transgressive marine shales. The Tookoonooka-Talundilly impact event may be an extreme prototype, as very few doublet craters, marine craters, impact tsunamiites, or economic impactites are individually known or preserved on Earth, yet this crater pair may represent all four. This impact crater pair provides a model for binary marine impact sedimentation and highlights the significance of ancient impact sediments to petroleum basins. Sedimentation patterns evidence a dual crater source even in a marine impact scenario where reworking and burial complicate the interpretation of depositional indicators; observations suggest that Tookoonooka-Talundilly may be the largest doublet crater discovered on Earth.Thesis (Ph.D.) (Research by Publication) -- University of Adelaide, Australian School of Petroleum, 2015.

Following the recent financial crisis when investors lost confidence in the value of loan securities, many companies have begun to change their business approach, methods, and strategies. While corporates pursue profits, the general public has focused on environmental protection, with an increasing emphasis on corporate social responsibility (CSR). This article thus discusses corporate governance after the recent financial crisis and its relationship with corporate performance by adding in the CSR variable. The empirical study investigates the top 50 Taiwanese electronics companies as denoted by Commonwealth Magazine, which are listed on the Taiwan Composite Stock Exchange or in the Over the Counter (OTC) market over the period 2009-2014. Company data come from the Taiwan Economic Journal (TEJ) Database, while CSR winners are from Wealth Magazine CSR Awards. This study mainly employs descriptive statistical analysis, correlation analysis, and regression analysis, with empirical results showing that corporate governance and corporate performance do have a significant relationship. In ROA, the cross effect of shareholding ratio and CSR is supported empirically, while in ROE, the cross effect of the largest shareholder ratio and CSR is supported empirically. Through the adjustment factor of CSR, managers are able to understand its deeper meaning and its correlation to corporate governance. While CSR activities cost companies a lot of time and money, fulfilling such social responsibility benefits are reflected in a company’s financial performance and can be used as a useful reference for decision-making.

The study mainly focuses on how mutual fund investors’ risk attributes, including risk tolerance, investment behavior, and reliance on financial consultants, are affected after the experience of the financial tsunami taking place in 2008. Mutual fund investors are divided into two categories: general investors and wealth management practitioners. Empirical results show that general investors become more conservative while wealth management practitioners remain active after the experience of the financial tsunami. After the financial tsunami, mutual fund investors narrow their bounds of realizing gains and losses and execute their orders more effectively, and that results in a lowered disposition effect. Previous studies indicate that investors reduce their trust on financial consultants after the financial tsunami. We find a contrast for the financial consultants in government-owned banks versus privately-owned banks: an increase in trust for the former while a decrease in trust for the latter after the financial tsunami. Finally, financial consultants loss confidence on their own profession after the tsunami.

ABSTRACT The global economic had been strongly influenced by the financial Tsunami, which starts the financial crisis in August 9, 2007. Since the subprime mortgage erupts and causes a succession of economic storm, the investors lose the confidence to the mortgage backed security. This event becomes the liquidity crisis, even if the central bank of many countries infuses the large amount fund to the financial market many times, the financial crisis still happened. Until 2008, the financial crisis starts out of control: the global stock market falls suddenly; many large-scale financial organs go out of business or are taken over control by the government. The Iceland even therefore goes bankrupt. After these events, many international investment banks goes out of business, the insurance company appears significant difficulty on management. The business model and the role localization should be pondered by the insurance company. In this financial Tsunami, American International Group (AIG) suffered the heavy losses. The AIG will go out of business if the government didn’t offer support. Except AIG, there are some large-scale insurance companies suffered the heavy losses in Europe and England. But there still some insurance companies with the same scale hadn’t come under the serious influence, for instance, the Prudential Financial (PRU). In this study, the reason forms the finance Tsunami will be discussed. The influences to the overall insurance business will also be made a comprehensive discussion in this study. This study is using the AIG and PRU as examples to discuss the reasons which enable two companies having such difference in this big Tsunami. The management idea, the management strategy and the financial report will be compared with AIG and PRU item by item. And try to finding the connection between the difference and management achievements, and also understanding the influences in company long-term development, management model and trade development by management idea and management strategy. AIG Corporation doesn’t narrate their management idea especially, so the company development has been following the opportunity. Because of no management idea, the management development is depended on the management strategy which is growing primarily, that is the service multiplication can enhance the overall company achievement stability. Therefore, AIG strengthens the life insurance service on the one hand; on the other hand, AIG speeds up entering the foreign insurance market and infiltrates 130 countries successfully. AIG Corporation has formed a defined expansion mentality gradually, which expanses to the domain of using the AAA rating, the abundant capital, the risk management skill and the intelligence capital. Under this expansion management strategy, the AIG Corporation decides to establish the American International Group Financial Products (AIGFP), enters the emerging derivative finance commodity market. Plants defeat’s seed. PRU thought that the enterprise management is a marathon, not a dash. In a marathon match, the personality and the moral character are more important than the technology. The moral character is more important especially in the unusual time; it is the key that makes the enterprise managing for a long time. Regarding PRU, “the talented person” who has the “engaged in the mind service” ability, who must have likewise the heart to the customer, who understands the customer’s demands, who always put the customer benefit first, and who makes the correct decision. Such personality, will not walk the shortcut because of the environment change in the unusual period, in addition the specialized technology, that’s why the service having “the quality.” The PRU management strategy makes its development way not expands outward, but increases the depth, starting from the staff’s moral specialty and the quality promotion. Which provides the customer to be more intimate, conforms to the demand product and the service, hoped that maintains longer-term relations with the customer. The different idea and the strategy make the corporate culture, the organizational structure, the development direction different. Business achievement has the enormous difference, so the company should have the explicit management idea establishment the main axle consensus building to be able the long-term stability development.

Affected by global financial tsunami, because of the product of collateral bond obligation (CBO) occupied great market share in Taiwan. Therefore, most CBO products that combined offshore derivates or bonds had endured huge impact; investors also lose their will of investment to CBO products relatively. Due to the effect of financial tsunami in Taiwan CBO securitisation market, the application of issuing CBO has reduced rapidly. The Main purpose of this essay will discuss of the participation in CBO, which include the effect of different designed models and structures, the risk factors and damage level to investors after financial tsunami and review the financial bureau’s policies and regulations of financial securitization at present. My research will focus on four independent cases, which is related to the part of CBO products that combined foreign bonds, and in order to find out the future direction of domestic CBO products; In these four cases, I will probe into the factors of gradually decreasing CBO market in Taiwan; the way of to give an impetus to CBO market again; the reason of investment lose and consider about if strengthen the responsibility and obligation to the counter party of CBO by deep interview. The conclusion of this assay: 1. Strengthen and confirm participant's purpose and ability of participating in securitisation, prevent the financial institutes from enthusing to be part of CBO market participation or in order to beautify their financial statements but making more financial problems. 2. Increase to disclosure investment risks and strengthen professional investment knowledge to all kinds of investors to prevent the lawsuit and avoid information dissymmetry. 3. Accelerate to regulate and modify Financial Asset Securitization Act to adapt the change of present securitization market. The Financial Bureaus should open their mind and improve Financial Asset Securitization Act more and quickly for increasing flexibility of products and improving management and monitoring methods after products issued. There is no relevant regulation or act to manage can be followed for Financial Bureau after issuing CBO products so far. Therefore, the government should have to draft and legislate as quickly as possible to benefit the management or monitoring CBO market.

To following with the financial structure improvement and economics growing strength, the emerging markets play a more important role in the world. It also attracts global investors’ eyes. The subprime mortgage, a alert to response the excessive financial operations in America and Europe, happened in U.S.A in April of 2007, and the bankrupt of Lehman Brothers Holdings Inc in September of 2008, a long history bank, caused the global financial tsunami still impacted us so far. During this time, the emerging markets have a vital characteristic of the financial risk aversion and let them grow up blooming. We can verify it from investing amounts growing doubled in the emerging marketing funds. The scholar studied continued in researching the fund performance in the past, and the emerging marketing was a relative newer research field. In this paper, we use the global emerging market bond funds as the samples. This purpose of this study was to investigate whether performance persistence and consistency existed during the financial tsunami of 2008. The paper uses three financial indicators of “Return”,” Sharpe ratio” and “standard deviation of net value” to analyze and classifies a long-term and a short-term period to verify fund performance persistence and consistency existed. It focuses on the financial tsunami, the significant financial issue, whether affected fund performance. Finally, it re-groups the specimens to identify the influence between fund performance persistence and the financial tsunami by using 5 non-financial indicators. This research adopts the method is coefficient correlation of Spearman to assay performance persistence. The research findings were summarized as follows: First, no matter in the long-term or the short-term period, Return and Sharpe ratio has performance consistency.Secord, the standard deviation of net value, a risk indictor, is obvious in long-term fund performance persistence.Third, considering the financial tsunami, Return and Sharpe ratio had the obvious negative coefficient correlation in both long-term and short-term fund performance persistence.Four, five non-financial indicators have different conclusions with analyzing the financial tsunami impact, especially in return for long-term and short-term fund performance persistence.

Taiwan is located at seismic zones. If the undersea trench near Taiwan triggers an earthquake over 9.0 on the Richter scale, the tsunami generated will impact directly on the coastal areas. The tsunami wave yields different impacts on flooding potential occurring at the coastal areas due to land topography and surface features. We apply the COMCOT (COrnell Multigrid COupled Tsunami model) model to simulate the tsunami transport of a scale 9.5 earthquake from the Ryukyu Trench dislocation. We also set up multiple tide observation stations in offshore areas during the simulation to observe changes in free surface when tsunami waves passed. The simulation results of the COMCOT model are then incorporated into the Physiographic Inundation Model as the downstream boundaries. We simulate the flooding potential of the Lanyang Plain with two scenarios: tsunami only, and tsunami and Typhoon Simlaku, 2008. The results show that tsunami generated from the Ryukyu Trench arrives the study area in 19 minutes; the first tsunami wave (the highest wave) with a height of 13.52 meters strikes the study area in 55 minutes. The results of flooding potential for the first scenario (tsunami only) show that the maximum flooded depth is 5 meters and the farthest flooded distance is 10.6 km. In the second scenario (tsunami and Typhoon Simlaku), the maximum flooded depth is 12 meters and the farthest flooded distance is 11.2 km. Comparing with these two scenarios, an increase of 7610 hectares in flooding areas can be observed since tsunami waves hinders the drainage of river channels.

YesDoggerland was a landmass occupying an area currently covered by the North Sea until marine inundation took place during the mid-Holocene, ultimately separating the British landmass from the rest of Europe. The Storegga Event, which triggered a tsunami reflected in sediment deposits in the northern North Sea, northeast coastlines of the British Isles and across the North Atlantic, was a major event during this transgressive phase. The spatial extent of the Storegga tsunami however remains unconfirmed as, to date, no direct evidence for the event has been recovered from the southern North Sea. We present evidence of a tsunami deposit in the southern North Sea at the head of a palaeo-river system that has been identified using seismic survey. The evidence, based on lithostratigraphy, geochemical signatures, macro and microfossils and sedimentary ancient DNA (sedaDNA), supported by optical stimulated luminescence (OSL) and radiocarbon dating, suggests that these deposits were a result of the tsunami. Seismic identification of this stratum and analysis of adjacent cores showed diminished traces of the tsunami which was largely removed by subsequent erosional processes. Our results confirm previous modelling of the impact of the tsunami within this area of the southern North Sea, and also indicate that these effects were temporary, localized, and mitigated by the dense woodland and topography of the area. We conclude that clear physical remnants of the wave in these areas are likely to be restricted to now buried, palaeo-inland basins and incised river valley systems.

In our study, we main to investigate the impact of interest rate risk on credit default swap (CDS) spread during financial tsunami. Empirically, we download US federal funds effective interest rate as well as the five-year CDS indices of the banking industry, the financial services industry, and the insurance industry from the DataStream. The sample period spans from January 1, 2008 to December 31, 2009. In estimation, we use the OLS and VAR approach to investigate the relationship over 2008-2009. The empirical result by employing the OLS method find that the interest rate risk is associated with the CDS spreads change in financial industries during the period 2008-2009. The same conclusion also holds in 2008. However, the interest rate risk has no significant effect on the change of CDS spreads in 2009. In addition, the empirical results by using VAR approach find that based on past interest rate risks, the managers and investors in financial industry could gauge their effects on the change of CDS spreads in 2008; the managers and investors in bank industry can do this gauge in 2009. In summary, in VAR model, we also can test the bidirectional causality between the interest rate risk and the change of CDS spreads in US financial industries. But the relationship will change with the sample period, therefore the managers and investors need to revise the estimated model. In addition, in the long-term interest rate risk will affect CDS spreads, it means that the interest rate risk and the change of CDS spreads have long-term stable relationship.

Individuals are importance resources for organizations. Optimal resource allocation and synergy are essential paths for improving the competitiveness of industries. Human resources are undoubtedly the most significant factor that influences the advantages of an enterprise. Under the trend of financial tsunami, the allocation of innovative human resource is the most unique strength of competitiveness, of which the differentiation effects are difficult to duplicate. In the era of intense competition and high concept, the work of employees is confronted simultaneously by financial tsunami and reduced orders. If innovative effects of human resources are to obtain direct efficacy, enterprises should create their competitive strength by utilizing professionals’ knowledge to manage companies. However, the formation of innovative strategies requires more aggressive policies that reform the established norms of manpower positioning. New strategies should be proposed to provide employees or enterprises with new values that guide them through financial difficulties. This study discussed the influence of manpower positioning and innovative strategies on the plastic industries under financial tsunami, as well as the relationship between manpower positioning and innovative strategies. In-depth expert interviews and surveys were conducted to collect data regarding recruitment, selection, payment, benefit, educational training, and career planning. Using stratified sampling method, this study distributed 600 surveys to plastic business owners, and obtained 513 valid samples. Analytical methods included ANOVA and IPA. Based on the analysis, this study proposed innovative manpower positioning strategies to ensure the appropriate employee numbers, employee quality and supply as well as to satiate enterprises’ needs to sustain the industry.

This study evaluates non-holding banks and financial holding company banks efficiency in Taiwan using DEA. This study mainly applies three-stage DEA-Window analysis model to research on banking performance. The data used in this study consists of information from 24 banks for the eight-year period from 2004 to 2011 in Taiwan. All sample banks, of which 10 for the general banking, 14 for the financial holding banks.In this study, dismantling of banking operations for marketing stage, operational stage and gain stage. Each stage has two input variables and two output variables. Therefore, we use the Window analysis method to measure the three-stage approach for non-holding banks and financial holding Taiwanese banks' operating efficiency, to answer the above questions. Study time for the 2008 financial crisis around the demarcation point in four years. Results of this study show that, overall, operational efficiency stage is the key point of the financial tsunami and the results show better able to withstand general banking financial tsunami.

In 2008, due to the substantial price-hike of global petroleum prices and the continuous rising of raw material prices, the whole world was subject to the threat caused by the increase of inflation. Finally, a financial tsunami evolved, and then came in a great surge. A series of chain reactions also impacted job markets directly, and hence tremendous unemployment tides developed. The purpose of this thesis was to explore the correlation among the psychological impact, family influence, crisis coping strategies, and career development when middle-level or high-level managers in Taiwanese enterprises encountered involuntary leaving the job. In this study, qualitative research methods were adopted. Related viewpoints given by the “middle-level or high-level managers” were obtained through In-depth Interview. Then, case studies were undertaken via auxiliary means such as related literatures, data and interview content. Finally, Cross Analyses were made, aimed at the interview content of the five samples, for finding out their meanings and differences, in order to understand the impact and influence of involuntary leaving the job on “middle-level or high-level managers”. The research findings indicated: This group of interviewed middle-level or high-level managers used to belong to the class who had very high employability and sense of work security and who had no need to worry about their short-term economy. Therefore, at the initial stage when they encountered involuntary leaving the job, no impact and significant influence were shown on their self-affirmation, career planning and families, even though they might have emotional reactions such as being astonished or surprised. However, after experiencing the unemployment periods which were longer than the ones they had expected, they began to have negative mentalities and emotions gradually, such as dejection, depression, dispirit, suffering, panic, sense of insecurity, and degraded confidence, along with economic pressure.
