Ao aproximarem-se os megaeventos esportivos no Brasil, a quantidade de discursos visando à ampliação e a promoção mais efetiva do esporte educacional, aumentam de forma exponencial. Ao pensar, portanto, na relevância de tal evento no contexto educacional do esporte, e a referência do estado de São Paulo na consecução de políticas públicas para o setor esportivo, o presente estudo teve o objetivo geral de investigar e analisar as políticas públicas de esporte educacional organizadas pela Secretaria de Esporte, Lazer e Juventude do estado de São Paulo (SELJ), considerando o contexto de realização dos Jogos Olímpicos de 2016. Os objetivos secundários versaram sobre: investigar como se dão as políticas públicas de esporte educacional da SELJ, inquirir se essas políticas visam um modelo de formação cidadã e analisar o impacto dos Jogos Olímpicos de 2016 nesses modelos. Dessa forma, foi utilizada, como ferramenta de coleta de informações e análise, a triangulação de dados. Foi adotada a utilização de entrevista semiestruturada, diário de campo e pesquisa documental. Constatou-se que o esporte educacional nas ações da SELJ apresenta-se a partir de duplo viés, adotando em alguns casos os predicados do alto rendimento, em outros os de participação. A formação cidadã é referida como finalidade dos projetos do esporte educacional na Secretaria, todavia tal iniciativa não é acompanhada pelos programas de ação propostos. A realização dos Jogos Olímpicos no País provocou o acirramento de novos discursos de legitimação da piramidização das políticas de esporte educacional. Também foi notado o caráter imediato e o incremento de discursos e algumas ações para o segmento. Assim, o processo de formação cidadã por intermédio do esporte educacional nos programas da SELJ, em tempos de megaevento esportivo compreende um cenário paradoxal / Abstract: Educational sport consisted of controversial ways in political history in Brasil, for being a large sportive manifestation, which involves either competitions based in selectivity and achievement of the best performance or projects which the goal is the sport's access and its democratization. As sports events are approaching in Brazil, the quantity of speeches aiming the enlarge and promotion of educational sports increases in exponential way. Therefore, thinking about the relevance of such event in the educational context of sport, and the reference of the State of Sao Paulo in attainment of the public policy for the sports sector, the goal of this study was to investigate and analyze the public policies of educational sport organized by Secretaria de Esporte, Lazer e Juventude (Department of Sport, Recreation and Youth) of Sao Paulo state, considering the context of the head of the Olympic Games of 2016. The secondary goals were: to investigate how the public policies of the educational sport of SELJ works, to inquire if these policies aim a citizen training and to analyze the impacts of 2016 Olympic Games in these models. This way, were used as a data collection tools, a semi-structured interview, field diary and documentary research. It was found that the educational sport on SELJ actions presents as double bias, in some ways adopting the predicates of high performance and another to participate. The citizen training is referred as the goal of the project of educational sport in the Department, however the initiative is not accompanied by the action programs proposed. The holding of Olympic Games in the country caused the worsening of new speeches of legitimation and pyramiding of educational sport policies. It was also noticed the immediacy and the increase of speeches and some actions to this segment. Thus, the process of citizenship through the educational sport in the SELJ programs comprises a paradoxical structure in times of sport mega events / Mestrado / Educação Fisica e Sociedade / Mestra em Educação Física

Nessa dissertação estudamos a evolução de alguma destas técnicas, apresentando a teoria e técnicas de simulação computacional para estudar transições de fase de primeira ordem com ênfase nas técnicas mais avançadas de calculo de energia livre (Reversible Scaling) e métodos de simulação de eventos raros (Forward Flux Sampling) usando a técnica de simulação atomística da Dinâmica Molecular. A evolução e melhora da e ciência destas técnicas e apresentada junto com aplicações a sistemas simples que permitem solução exata e também ao caso mais complexo da transição de fase Martenstica. Também apresentamos a aplicação de métodos numéricos no estudo do modelo de Pauling para o gelo. Nos desenvolvemos e implementamos um novo algoritmo para a criação e ciente de estruturas de gelo desordenadas. Este algoritmo de geração de cristais de gelo nos permitiu criar células de gelo Ih de tamanhos que não eram possíveis antes. Usando este algoritmo abordamos o problema de efeitos de tamanho finito não estudados anteriormente / Abstract: Due to the conceptual and technical advances being made in computational physics and computational materials science we have been able to tackle problems that were inaccessible a few years ago. In this dissertation we study the evolution of some of these techniques, presenting the theory and simulation methods to study _rst order phase transitions with emphasis on state-of-the-art free-energy calculation (Reversible Scaling) and rare event (Forward Flux Sampling) methods using the atomistic simulation technique of Molecular Dynamics. The evolution and efficiency improvement of these techniques is presented together with applications to simple systems that allow exact solution as well as the more the complex case of Martensitic phase transitions. We also present the application of numerical methods to study Pauling\'s model of ice. We have developed and implemented a new algorithm for efficient generation of disordered ice structures. This ice generator algorithm allows us to create ice Ih cells of sizes not reported before. Using this algorithm we address finite size effects not studied before / Mestrado / Física / Mestre em Física

Há muitos anos diversos experimentos espalhados pelo mundo, dedicados à detecção de raios cósmicos, vêm coletando e montando uma estatística bem estabelecida do fluxo, direção de chegada, energia e composição química até 1019 eV através do constante desenvolvimento de novas técnicas. Ficou comprovado, porém, que radiação cósmica acima de 1020 eV existe, uma contradição com previsões teóricas que imediatamente abriu um leque de questões, variando desde qual origem extragalática poderiam ter, até o modo como se propagam pelo espaço. A riqueza e detalhamento que o estudo dessas partículas envolve são sintetizados em três partes neste trabalho. O primeiro capítulo aborda a radiação desde suas mais prováveis fontes geradoras e mecanismos de aceleração, os efeitos a que está sujeita durante a propagação pelo espaço e, por fim, o conjunto de processos desencadeados a partir da chegada no topo da atmosfera terrestre até o nível do solo -o chamado chuveiro atmosférico extenso. Com essa motivação inicial, a segunda parte abrange a totalidade do que será o Projeto Auger em sua fase final: um observatório que emprega as duas técnicas mais bem sucedidas já utilizadas em outros experimentos de menor porte, juntamente com a física, a matemática e o embasamento computacional da análise e reconstrução das propriedades que caracterizam uma partícula primária. No último capítulo é colocado em prática tudo o que foi discutido no anterior , com algumas restrições existentes na época em questão. A mais evidente é o funcionamento do observatório como um protótipo, quando foram operadas apenas parte de um olho (conjunto de telescópios de fluorescência) e do arranjo de solo. Outra são os códigos disponibilizados para análise pela colaboração, em constante desenvolvimento em paralelo com simulações. Uma análise completa da reconstrução geométrica e energética de todos os eventos registrados é apresentada e depois confrontada com resultados de outros membros da colaboração, dando um panorama geral do que se propõe o projeto no futuro, quais seus principais aspectos a serem melhorados e que ferramentas de análise ainda devem ser desenvolvidas / Abstract: This dissertation covers the analysis of the first events detected simultaneously by water tanks and fluorescence telescopes during the prototype phase of the Pierre Auger Observatory, between December 2001 and April 2002. For years several experiments over the world dedicated to the detection of cosmic rays collected and built a well established statistics for the flux, arrival direction, energy and chemical composition up to 1019 eV with the constant development of new techniques. It is a fact, though, that cosmic radiation over 1020 eV exists, a contradiction to previous theoretical results that immediately raises questions like which extragalactic origin they could have or how they propagate through space. The richness and level of detail involved in the study of such particles are synthesized in three parts in this work. The first chapter approaches cosmic radiation from its most likely sources and acceleration mechanisms, the effects to which it is subjected during propagation through space and, at last, the set of processes caused by the arrival at the top of the Earth's atmosphere to the ground level -the so-called extensive air shower . After this initial motivation, the second part covers the totality of what is to be the Auger Project in its final phase: an observatory that employs the two most successful techniques ever used in other smaller-scale experiments, along with the physics, mathematics and computational basis of the analysis and reconstruction of the properties that characterize a primary particle. Everything discussed previously is put into practice in the last chapter, with some of the restrictions at the time. The most evident is the operation of the observatory as a prototype, when only parts of one eye (set of fluorescence telescopes) and surface array were available. Another one are the codes available to analysis by the collaboration, in constant development in parallel with simulations. A complete analysis of the geometry and energy reconstruction of all events registered is presented and cross-checked with results from other collaboration members, giving a general view of the project's proposal for the future, its main aspects to be improved and which analysis tools are still to be developed. / Mestrado / Física / Mestre em Física

M.Com. (Financial Management) / This study was an investigation into the impact of hosting the FIFA World Cup soccer tournament on the stock market of the host country. The investigation looked at whether stock markets react efficiently or show a positive reaction to the hosting of the FIFA World Cup. Hosting the FIFA World Cup was assessed at two event dates: the announcement date where the host country’s winning bid is announced and the when the tournament starts. An event study research methodology was used to investigate the impact of hosting the FIFA World Cup on the stock exchange of the host country, by examining the movement of CARs across the two event windows. It was found that stock markets react differently to the announcement of the tournament and event start dates. The results of this study show that the stock market does not always regard the hosting of the FIFA World Cup as positive news, therefore resulting in either a positive or negative stock market reaction. Markets do however appear to be efficient and incorporated all information in stock prices. The test statistics showed a number of statistically insignificant results; hence the presented results do not support the hypotheses that the FIFA World Cup has a significant impact on the host country stock market during the announcement and hosting stages.

Sammanfattning Bakgrund: Antalet transporter mellan sjukhus, som kräver medföljande anestesipersonal, har ökat i region Jönköpings län från 135 stycken 2015 till 247 transporter 2016. Anestesisjuksköterskans arbetsuppgifter är bland annat att övervaka, observera, dokumentera och följa upp patientens ventilation, cirkulation, anestesidjup och temperatur. Att vårda patienter i ambulans är en stor utmaning eftersom situationen är komplex och oförutsägbar. Syfte: Syftet är att beskriva anestesisjuksköterskors erfarenheter och agerande i samband med kritisk händelse under ambulanstransport av svårt sjuk patient. Metod: Kvalitativ design med hjälp av intervjuer utfördes med Critical Incident Technique (CIT). En incident liknas vid en situation, ett dilemma eller enskild händelse som i efterhand betraktas som kritisk. Kritiska händelser definieras i  denna studie som händelser eller specifik situation med positiv eller negativ utgång. Resultat: Tre huvudområden söktes i resultatet, trygghet, kontroll och utsatthet. Anestesisjuksköterskorna upplevde att transportsituationen var en utsatt uppgift, trots flera år som anestesisjuksköterskor och mångårig yrkeserfarenhet utöver det. Det beskrevs som det värsta med jobbet och var inget som någon längtade efter. Slutsats: Anestesisjuksköterskor känner sig ofta otrygga, utsatta och har svårt att behålla kontrollen över situationen under ambulanstransporten.

There is growing concern for increased frequency of extreme events due to several severe floods and droughts occurring globally in recent years. Improving knowledge on the complexity of hydrological systems and interactions with climate is essential to be able to determine drivers and predict changes in the future. This is especially true in cold regions such as the Swedish Subarctic. This thesis explored changes in high peak flows and linked trends to climate. Trend analyses were applied on 18 catchments in the Swedish Subarctic over their entire periods of record and a common period (1990-2013) among the data to explore changes in flood magnitude, flood occurrence, mean summer flow, snowmelt onset and center of mass. Further, a flood frequency analysis was applied using the extreme value type I (Gumbel) distribution and selected flood percentiles were tested for stationarity. The results show the complexity of the hydrological system and interactions with climate. No clear overall pattern could be determined suggesting that changes are happening at catchment scale. Indications for a shift in flow regime from snowmelt-dominated to rainfall-dominated are evident with all significant trends pointing towards lower flood magnitudes in the spring flood, earlier flood occurrence and snowmelt onset, and decreasing mean summer flows. The shift in flow regime suggests that air temperature is more clearly reflected in streamflow than precipitation in the Swedish Subarctic. Decreasing trends in flood magnitude and mean summer flows are suggestive of permafrost thawing, which agrees with the increasing trends in the annual minimum flow. Long streamflow records can further link variability in streamflow to multidecadal atmospheric circulations over the North Atlantic. Most evident are changes towards lower mean summer flows (ten catchments significant at a 95% confidence interval) and earlier snowmelt onset (eight catchments significant). Trends in the selected flood percentiles show indications towards an increase in extreme events over the entire period (significant for four catchments), with all significant trends being positive. Over the common period, no pattern is notable and the sensitivity of trend analyses is evident.

This empirical study is concerned with the extent to which news announcements affect the performance of common equity securities of oil and gas producing companies. The market effects of news announcements are considered to be of importance in resolving two issues. One concerns financial statement disclosure and the second concerns examination of prior oil and gas industry-related accounting research. This dissertation assumes capital market efficiency and addresses two research questions: do news announcements concerning activities of nonintegrated oil and gas producing companies affect the companies' common stock prices, and are announcements concerning nonintegrated oil and gas companies' financial, personnel, explorational, and developmental and operational activities used equally by investors in their decision-making?

Psychogenic nonepileptic seizures (PNES) are abrupt paroxysmal changes in behaviour, sensation, or experience that mimic epilepsy, but that are not accompanied by the electrophysiological changes typical for epilepsy. Their cause is psychological. An examination of neuropsychological correlates of PNES is therefore crucial for understanding, effective diagnosis and treatment of this disorder. The aim of our study is to explore a specific neuropsychological profile of patients with PNES, particularly cognitive impairment, early parental bonding and occurrence of selected life events during childhood and before the onset of PNES. We examined 38 patients with PNES and 38 healthy controls matched for age and sex using neuropsychological battery RBANS, PBI questionnaire and a checklist of life events. The results showed that overall cognitive performance of patients with PNES was significantly worse in comparison with healthy controls. However, there was no significant difference between the two groups in immediate memory and language domains. Furthermore, patients with PNES recollected significantly more paternal control in childhood, more stressful situations, more opportunities for social learning of the sick role, more health problems in childhood and also significantly more troubles preceding the...

Les coups de vent d’ouest (WWEs) issu de la variabilité synoptique atmosphérique jouent un rôle crucial dans les irrégularités d’ENSO en contribuant au déclenchement et au développement de sa phase chaude, El Niño. Les WWEs sont des événements haute fréquence peu prévisibles et dont les origines atmosphériques restent encore débattues. Dans le but d’affiner la prévisibilité d’ENSO, cette thèse caractérise la part stochastique de la part prévisible des WWEs ainsi que de leur réponse océanique et couplée. Dans une première partie, j’ai relié l’occurrence et les caractéristiques des coups de vent à des phénomènes de grande échelle comme l'oscillation de Madden-Julian, les ondes de Rossby atmosphériques et ENSO, à partir d’analyse d’observations. Ensuite, la forte sensibilité de la réponse océanique des WWEs à l’état de l’océan a été mise en évidence grâce à une série de simulations océaniques forcées. Finalement, une simulation d’ensemble réalisée avec un modèle couplé océan-atmosphère a permis d'explorer le rôle des WWEs dans l’évolution contrastée des années 1997,2014 et 2015 qui présentaient des conditions similaires et favorables au déclenchement d'El Niño. Les résultats de ce travail montrent que la stochasticité des WWEs aboutit à une limitation intrinsèque de la prévisibilité des caractéristiques d’El Niño. / Equatorial Pacific Westerly Wind Events (WWEs) impact ENSO evolution through their oceanic response and strongly contribute to its irregularities. WWEs are characterized by episodes of anomalous, short-lived, strong westerlies developing over the western Pacific warm pool. This thesis characterize the atmospheric origins and the oceanic and coupled impacts of these events in order to improve ENSO prediction. First, we show that, at intraseasonnal timescale, the Madden-Julian oscillation and the convectively coupled Rossby waves provide favourable conditions for the occurence of WWEs and confirm their modulation by ENSO at interannual timescale. Oceanic simulation with idealized forcing further allow characterizing and understanding the modulation of the SST response to WWE by the oceanic background state. Finally, The role of WWEs in the contrasted evolution of El Niño in 1997,2014 and 2015, which exhibited favourable conditions for El Niño to develop, is explored in ensemble simulations using a coupled ocean-atmosphere model. It is shown that the stochasticity of the WWEs acts as a strong limitation for ENSO predictability.
