Nous étudions certains processus de Lévy à valeurs dans les groupes d'isométries respectifs des espace-temps de Minkowski, de De Sitter et de Anti-De-Sitter. Le groupe d'isométries est vu comme le fibré des repères de l'espace-temps et les processus de Lévy considérés se projettent sur le fibré unitaire en un processus markovien relativiste ; c'est-à-dire que les trajectoires dans l'espace-temps sont de genre temps et que le générateur est invariant par les isométries. Dans la première partie nous adaptons pour les diffusions hypoelliptiques générales un résultat de Ben Arous et Gradinaru concernant la singularité de la fonction de Green hypoelliptique. Nous déduisons de cela un critère d'effilement de Wiener local pour les diffusions relativistes dans le groupe de Poincaré, groupe des isométries de l'espace-temps de Minkowski. Dans les deux dernières parties nous nous intéressons au comportement asymptotique du flot stochastique associé à ces processus de Lévy dans les différents groupes d'isométries. Sous une condition d'intégrabilité de la mesure de Lévy nous calculons explicitement les coefficients de Lyapounov des processus dans le groupe de Poincaré. Nous effectuons un travail similaire pour les espace-temps de De Sitter et Anti-De-Sitter en nous limitant au cas des diffusions. Nous explicitons de plus la frontière de Poisson pour la diffusion dans le groupe d'isométries de l'espace-temps de De Sitter.

Taip pat parodyta, kad atitinkamai normuotos $\bar X_t$ dalinės sumos konverguoja į trupmeninį $\alpha-$stabilų judesį. Ir esant tam tikroms sąlygoms ribinis agreguotas procesas $\{\bar X_t\}$ turi LRD(SAV) (angl. long-range dependence (sample Allen variance)) sąvybę, bei skirstinių ilgąją atmintį. Šis darbas išplečia kai kuriuos P.

Particular attention is given to the case of slope coefficient having probability density growing regularly to infinity at points $a = 1 $ and $a=-1$. Conditions are obtained under which the limit aggregate $\bar X_t = \lim_{N \to \infty} N^{-1}\sum_{i=1}^N X_{i,t} $ exists and exhibits long memory, in certain sense. In particularly, I show that suitably normalized partial sums of the $\bar X_t$'s tend to fractional $\alpha-$stable motion, and that $\{\bar X_t\}$ satisfies the long-range dependence (sample Allen variance) property and distributional long memory. The present paper also extends some results of P. Zaffaroni from finite variance case to infinite variance case.

This thesis is concerned with the relation between bank regulation and the risk-taking behaviour of banks. Two major instruments of regulatory intervention are considered: bank levy and bank bailouts. The major objective of this thesis is to provide an answer to the following questions: Do bank levies increase the risk-taking of banks in a competitive environment? When do bank bailouts decrease banks` risk-taking? Does the international coordination of bank bailouts affect the relation between bailouts and the risk-taking behaviour of banks? Who should rescue subsidiaries of multinational banks? How could an efficient bailout policy be designed and implemented? The bank levy and cooperation between national regulators play an important role in the recently adopted Bank Recovery and Resolution Directive (BRRD). This directive is a cornerstone of bank regulation in Europe. Although the conversion of debt into equity (bail-in) in emergencies is the key component of the current regulation, bailouts, or at least the assistance to struggling banks, should not be excluded. As the ordinary resolution tools, for instance, bail-in, have not yet been tested in a real crisis, and due to the fact that it will take time to prepare global institutions for such a tool, it may be useful to have an adequately designed tool of last resort available, such as an adequate bailout policy, in order to avoid the disruption of critical economic functions. We show that a bank levy may decrease banks`risk-taking behaviour. Bank bailouts can also decrease the risk-taking of banks. This depends on the regulator`s ability to condition his bailout policy in accordance with the macroeconomic environment, which has an impact on the banks` probability of success, or on his ability to condition the bailout policy on the banks` systemic relevance. Coordination of bailouts through a multinational regulator can improve welfare. The desirability of internationally coordinated bailouts depends on the dimension of the crisis. If the crisis is severe, it may be more efficient to delegate bank bailouts to a multinational regulator. However, such a delegation is not always feasible. Therefore, a predefined burden sharing of bank bailouts is necessary in order to achieve an efficient resolution of banks in distress.

Este estudo volta-se para a temática do lazer e envelhecimento, tendo como foco os corredores de rua. Entre os diferentes níveis de empenho, em que o esporte pode ser praticado, este estudo trabalha com o grupo de praticantes de corrida de rua, que dedicam bastante tempo e esforço de forma sistemática nesta atividade. Foi eleito um grupo de corredores dentre uma numerosa lista de grupos de corrida de rua que se formaram nos últimos anos na cidade de Porto Alegre, capital do Estado do Rio Grande do Sul. Observações, conversas, fotos, troca de e-mails e outros dados foram coletados na intenção de buscar variadas perspectivas sobre os fenômenos observados. Com uma abordagem de caráter etnográfico, busca-se identificar, analisar e interpretar manifestações que indicam relações entre a prática da corrida de rua e o envelhecimento dos corredores. Essas práticas são entendidas como “lazer sério”, conceito proposto pelo sociólogo Robert Stebbins. Evidenciam-se no trabalho as formas com que são dinamizados aspectos do envelhecimento dentro de um grupo de corrida e suas relações com um contexto mais amplo. Essas manifestações são entendidas como “realizações”, e os processos dinâmicos, entendidos como “atualizações”, baseado no trabalho do filósofo Pierre Lévy. Formas de enfrentamento de adversidades, comunicação, dentre outras “realizações” apontaram para movimentos ambivalentes e interdependentes presentes no “lazer sério”. Estes orientam para novas possibilidades de envelhecimento, novos estilos de envelhecer. As principais “realizações” se manifestaram nas categorias de ironia, loucura, vírus, transgressão e volta, sintetizando formas com que os corredores lidam com a corrida e suas relações com a velhice e o envelhecimento. Dentro de uma tridimensionalidade composta pelas interações dos corredores dentro do grupo, com a sociedade e consigo mesmos, essas “realizações” revelam configurações criativas e inovadoras de aprender, ensinar e alterar a velhice e o envelhecimento a partir de estilos de envelhecer que surgem na prática do “lazer sério”. / This study turns to the theme of leisure and aging, focusing on the street racers. Between different levels of commitment, in which sport can be practiced, this study works with a group of runners, who devote considerable time and effort in a systematic way in this activity. He was elected a group of runners among a large list of running groups that have formed in recent years in Porto Alegre, capital of Rio Grande do Sul. Observations, conversations, photos, exchange e-mails and other data were collected on the intention to seek different perspectives on the phenomena observed. With an ethnographic approach, we seek to identify, analyze and interpret events that indicate relationships between the practice of road race and the aging of the runners. These practices are regarded as “serious leisure”, a concept proposed by the sociologist Robert Stebbins. Show up at work the ways in which aspects of aging within a runners group is related with a broader context. These manifestations are understood as “realizations”, and the dynamic processes, understood as “actualization” based on the work of the philosopher Pierre Lévy. Ways of coping with adversity, communication, among other “realizations” pointed to these movements ambivalent and interdependet at “serious leisure”. These guide for new possibilities of aging, new aging styles. The main “realizations” were manifested in the categories of irony, insanity, viruses, transgression and back, recapitulating the ways in which the runners deal with old age and aging. Within a three-dimensional composite by interactions within the group of runners, with society and themselves, these “realizations” show settings creative and innovative learning, teaching and changing old age and aging from aging styles that arise in the practice of “serious leisure”.

nÃo hà / Este trabalho tem por objetivo investigar a relaÃÃo entre a polÃtica econÃmica do estado do Cearà vis à vis os demais estados do Nordeste, em funÃÃo da evoluÃÃo da arrecadaÃÃo do Imposto sobre CirculaÃÃo de Mercadorias e ServiÃos de Transporte Interestadual e Intermunicipal e de ComunicaÃÃo (ICMS). Os dados das arrecadaÃÃes estaduais foram obtidos no site do Conselho Nacional de PolÃtica FazendÃria (CONFAZ), no perÃodo de Janeiro/2005 a Dezembro/2013. A anÃlise inicial das correlaÃÃes entre as arrecadaÃÃes do Estado do Cearà e as arrecadaÃÃes dos demais estados do Nordeste demonstrou uma associaÃÃo em torno de 95%, sugerindo a ocorrÃncia de um crescimento conjunto de toda regiÃo Nordeste. Por fim, comparou-se a evoluÃÃo da arrecadaÃÃo do Cearà à mÃdia da arrecadaÃÃo dos estados nordestinos e foram realizados os testes de raiz unitÃria ADF e KPSS para investigar a sua tendÃncia de longo prazo. Os resultados indicaram a possibilidade de cointegraÃÃo entre as evoluÃÃes da arrecadaÃÃo do ICMS do Estado do Cearà com a maioria dos estados do Nordeste, com exceÃÃo dos estados do PiauÃ, Rio Grande do Norte e Alagoas. AlÃm disso, observa-se um crescimento do ICMS cearense de Janeiro/2009 a Janeiro/2010 acima da mÃdia regional e um aparente arrefecimento desse crescimento a partir dessa data. / This study aims to investigate the relationship between the state economic policy of Cearà vis à vis the other states of the Northeast, in line with developments of the collection of the Tax on Circulation of Goods and Interstate and Intermunicipal Transportation and Communication Services (ICMS). Data from state collections were obtained from the website of the National Council for Financial Policy (CONFAZ), from January/2005 to December/2013. The initial analysis of the correlations between the collections of the State of Cearà and the collections of other states of the Northeast showed an association around 95%, suggesting the occurrence of a set growth throughout the Northeast. Finally, he compared the evolution of the collection of Cearà the average collection of the northeastern states and unit root tests were performed ADF and KPSS to investigate its long-term trend. The results indicated the possibility of cointegration between the evolutions of Cearà State ICMS collection with most Northeastern states except the states of PiauÃ, Rio Grande do Norte and Alagoas. In addition, there is an increase in Cearà ICMS January/2009 to January/2010 above the regional average and an apparent cooling of this growth thereafter.

Essa necessidade se impõe pelo fato de que, em ambas as narrativas, as personagens são marcadas por percursos exílicos e/ou diaspóricos, além do fato de a condição judaica destas ser influenciada pela necessidade da escrita de seus conflitos íntimos e da sua memória; portanto, da consequente reescrita de si através da leitura dos arquivos que as constituem. Em virtude disso, ambas as personagens experimentam a condição vivenciada pelo estrangeiro, o desterritorializado que – no que concerne aos romances em estudo – busca na escrita um lar possível e percebe que esta é tão ambivalente quanto sua própria condição. Desse modo, será analisada a concepção identitária do sujeito que narra, já que, em virtude de ser diaspórico, apresenta o que Igel (1997) entende por “identidade em dobradiça”, e seu diálogo com a estrutura dos romances contemporâneos que trazem em seu cerne elementos ligados ao judaísmo, já que estes se caracterizam pela ausência de linearidade e pela fragmentação. Para isso, filiamo-nos aos pensamentos desenvolvidos por Scliar, Vieira, Derrida, Sorj, Lilenbaum, Kurtz, Lessa, Hall, Halbwachs, entre outros estudiosos das questões levantadas por esta pesquisa. Contudo, são os universos ficcionais de Levy e Laub, especificamente no que concerne aos romances A chave de casa e Diário da queda, que nos servem de norte principal

This thesis provides an overview of extra-contractual legal institutions of the use of copyrighted work. The main emphasis is on the institution of free use and related topic of private copying and fair compensation. Statutory licenses, both chargeable and free of charge, are not omitted. The thesis is divided into three chapters. Brief introduction is followed by chapter providing definition of the fundamental terms of copyright from the perspective of Czech copyright law. The second chapter contains summary of sources of copyright law. Czech law, as well as European and international law is included. The third chapter contains crutial part of the thesis, the analysis of the extra-contractual legal institutions of the use of copyrighted work. After brief comment on free works follows analysis of the Three-Step Test, which is of great significance for all examined legal institutions. Relevant case law - WTO Panel report WT/DS160/R - is examined and the Max Planck Institute's Declaration on a balanced Interpretation of the Three-Step Test is also considered. Subsequent subchapters are dedicated to the institutions of free use and private copying under both, Czech and European copyright law. The thesis also includes comparative analysis of the level of the private Copying levies in the EU, based on...

- ENGLISH The content of this thesis is aimed towards the interpretation of the so-called non- contractual legal institutions of the use of copyrighted work. These institutions represent such legal tools, that exceptionally allow individuals different from the author to exploit copyrighted work with no dependence on the author's permission or will. The text of the work is divided into four main chapters. For introduction into the matter, the opening part is dedicated to the explanation of the term copyright law, its position in the Czech legal system and the main principles it lies upon. This broad explanation is subsequently followed by definition of its fundamental terms - author's work and its use. The crucial part of the work lies in the fourth chapter, which bears the same title as the work itself. The structure of this chapter follows the organisation of the Czech Copyright Act. After description of the free work, the paper gets to the interpretation of individual exemptions and limitations to copyright, thus the institutes of free use and statutory licences. In relation with the matter of exemptions and limitations to copyright, the work does not forget to deal with their key tool, the Three-Step Test, and its related significant interpretation performed by The Dispute Settlement Body at...
