L’Organisation de la Coopération Islamique (OCI) créée en 1969 suite à l’incendie de la mosquée Al-Aqsa, représente la voix du monde musulman. C’est la deuxième organisation intergouvernementale après l’ONU regroupant cinquante-sept Etats membres aux quatre coins du monde.Un Programme d’Action Décennal (PAD) a été adopté lors du 3ème Sommet islamique extraordinaire réuni en 2005. Le PAD vise une nouvelle vision pour le monde musulman : « la solidarité dans l’action ».Cette thèse étudie l’évolution du rôle de l’OCI pour relever les défis politiques, économiques, sociaux et culturels qui surgissent sur la scène internationale et affectent la communauté musulmane. Elle met l’accent sur les points réalisés du PAD et les entraves de l’OCI à établir l’unité de l’Oummah islamique. / The Organization of Islamic Cooperation (OIC) has been established in 1969, following the fire of the Al-Aqsa mosque. This organization represents the voice of the Islamic world and it is considered according to its membership, the second intergovernmental organization after the UNO. OIC includes fifty seven member states coming from all over the World.A Ten-year Program of Action (TYPOA) has been adopted in 2005 during the third extraordinary Islamic Summit, aiming at establishing a new vision for the Islamic World called: « Solidarity into action ».This thesis discusses the evolution of the role of the OIC relating international challenges of political, economic, social and cultural nature that the Islamic communities have to face. The thesis points out the matters that have been achieved through the TYPOA and the obstacles that the OIC faced regarding the necessity to unify the Islamic Ummah.

Segregation is frequently described as a consequence of the global restructuring of social, economic, and political expansions in which multicultural cities, like Malmö, become part of them. This study aims to highlight how visions of housing segregation and exclusion in the city of Malmö has been represented in the local policy documents (Master Plans) through the last three decades and to understand how a newly emerged glocal actor, known as BID Malmö, have impacted the urban governance in the city. In order to investigate these developments, this study applies two analytical frameworks. In terms of policy analysis, it employs a what’s the problem represented to be? (WPR) approach and for the conceptualization of BID Malmö applies the theory of the Global City. Policy analysis shows that urban segregation has been persistent in the city of Malmö through the last three decades, however the representation of problem has shifted vibrantly from placing citizens as the main cause of housing segregation during 1990s to an arena that includes contingent processes and practices that need to be tackled. Policy analysis also shows that Malmö municipality, through shifting the burden of responsibility, now promotes partnership between public and private actors to reduce exclusion based on specific district needs. Moreover, this study argues that the city of Malmö, because of the cross-border network of global cities, is now a space where one can identify formation of new types of global politics of place where informal political actors are emerging and can actually impact the urban governance. Finally, this study maintains that the city of Malmö, along with its newly emerged glocalized actor, fit into the theory of the Global City, by Saskia Sassen. Therefore, this study has also a deductive qualitative analysis.

Quantification of the influence of type construction is realized for the purpose of determining the market price of flats by using comparative method of valuation. Comparative method is based on the market principle. Comparative method is based directly on a comparison of sales similar properties in similar conditions. Comparing price of comparative properties and appraised property is performed by using a number of criteria of significant differences, the evaluation of these criteria are quantified by using the coefficients of differences. In practice is usual to provide the range and number of coefficients based on professional judgment. The most important coefficients in comparative method of valuation are location, technical characteristics, equipment, accessories, property rights, other relevant factors and mainly the coefficient of influence of type construction is one of the most important factors of pricing. Due to this fact based on the analysis of public available sources (mostly from real estate server www.sreality.cz) is set, how the price is affected by the type of flat construction. During the creation database and it´s layout was found, that one of the pricing factor for the type of structure is insulation, therefore is this factor also considered.

Diploma thesis deals with the analysis of the approach of construction companies to the preparation of price offers. The theoretical part contains an explanation of the basic concepts of the issue and possible ways to determine the price of the construction work. In the practical part, this topic is researched in practice using a questionnaire survey. The results of the questionnaire survey are followed by two interviews with representatives from practice. After evaluating these data, the established hypotheses are verified and recommendations are expressed.

Main objective of this thesis is to determine the process for rent calculation of flats in line with presumptions influencing dependence of rent on common flat price. Proposed methodology is based on presumption of investing in property and possible yields or risks of this investment. The work studied the effects of correlation rentals and flat price.

The purpose of this essay has been to attain an in-depth understanding of communicative power struggles within the urban space from a critical urban perspective based on the Right to the City. The project that constitutes the case study for this analysis has been the BID Malmö’s utility box project. The starting point has been that Malmö’s utility boxes function as a communicative medium, an urban public bulletin board, a common whose usage is constrained by projects implemented by entities like BID Malmö. The study is grounded in a theoretical understanding of the city as a social product, marked by power struggles linked to the competitive, postindustrial city. Critical urban theory has been combined with a discourse-oriented ctitical perspective focusing on power, ideology and hegemony, forming the basis for the conducted critical discourse analysis. The findings of the study reveal that art and culture are assigned a central role in the postindustrial city, tasked with transforming urban space. The transformation from a dirty or unsafe current to a safe and attractive futurecity. At the same time, culture is assigned a commitment to fostering participation, even as the same art is used to enclose and restrict certain parts of the public space. / Syftet med denna uppsats har varit att nå fördjupad kunskap om det urbana rummets kommunikativa maktkamper utifrån ett kritiskt urbant perspektiv om Rätten till staden. BID Malmös elskåpsprojekt har utgjort undersökningens fallstudie. Utgångspunkten har varit att Malmös elskåp är ett kommunikativt medium, en urban offentlig anslagstavla, en allmänning. Vars användning begränsas genom olika projekt som genomförs av bland andra BID Malmö. Undersökningen förankras i en teoretisk förståelse för staden som socialt producerad och präglad av maktkamper kopplade till den konkurrerande, postindustriella staden. Den kritiska urbana teorin har kombinerats med ett diskursteoretiskt perspektiv med fokus på makt, ideologi och hegemoni. Vilka tillsammans har lagt grunden för den genomförda kritiska diskursanalysen. Resultatet av undersökningen visar att konsten och kulturen tillskrivs en central roll i den postindustriella staden, vars uppgift är att omskapa rummet till något annat än vad det är idag med fokus på trygghet och stadens attraktivitet. Kulturen tillskrivs ett åtagande att skapa delaktighet, samtidigt som samma kultur används för att inhägna och stänga ner delar av det offentliga rummet och minska rätten till staden.

[pt] A possível mudança no paradigma de formação de preço no Brasil do modelo vigente por custos auditados para o modelo por oferta, com o objetivo de modernizar o Setor Elétrico e buscar práticas que incentivem a competição, implica a necessidade de estudos prévios para auxiliar o processo de transição e a definição do desenho de mercado adequado à realidade brasileira. Nesse sentido, o uso de modelos de equilíbrio, notadamente o Equilíbrio de Nash, desponta como uma poderosa ferramenta ex-ante que permite analisar o comportamento dos competidores para identificar possíveis ineficiências a serem mitigadas. Com esse fim, o presente trabalho modela o processo decisório de ofertas ótimas de um competidor em um mercado de energia elétrica de dia-seguinte de base hidrotérmica por um modelo de otimização binível, possibilitando a identificação do Equilíbrio de Nash do mercado através de um algoritmo baseado em Gauss-Seidel. Adicionalmente, o método é aplicado a dois experimentos numéricos: a um sistema-teste de três barras e a um caso representativo do sistema brasileiro completo, permitindo a análise do comportamento dos competidores a partir da comparação dos resultados com os modelos de Custos Auditados e Equilíbrio Competitivo. Foram observados os impactos das afluências e das cascatas de usinas hidrelétricas de múltiplos proprietários nas receitas e, consequentemente, no comportamento dos competidores. Por fim, foi verificada a ocorrência de competição exclusivamente pelas quantidades, além da prática de retenção de ofertas por parte dos competidores para a modificação do preço de equilíbrio de mercado, aumentando suas receitas. / [en] The potential shift in Brazil s energy pricing paradigm from the current Audited Costs model to the Bid-Bases model, with the aim of modernizing the electricity sector and seeking practices that encourage competition, implies the need for preliminary studies to assist the transition process and define the appropriate market design for the Brazilian reality. In this sense, the use of equilibrium models, notably the Nash Equilibrium, emerges as a powerful ex-ante tool that allows the analysis of competitors behavior to identify possible inefficiencies to be mitigated.To this end, this thesis models the optimal bidding decision process of a competitor in a hydrothermal day-ahead electricity market using a bilevel optimization model, enabling the identification of the Nash Equilibrium of the market through an algorithm based on the Gauss-Seidel. Additionally, the method is applied to two numerical experiments: a three-bus test system and a representative case of the complete Brazilian system, allowing for the analysis of competitors behavior by comparing the results with the Audited Costsand Competitive Equilibrium models. The impacts of water inflows and hydro plants in cascade with distinct ownership on revenues and consequently competitors behavior were observed. Finally, the occurrence of competition exclusively in quantities was verified, as well as the practice of quantity bids retention by competitors in order to modify the market equilibrium price, increasing their revenues.

[pt] Esta tese investiga a estimação de curvas de juros sob o ponto de vista de métodos não-paramétricos. O texto está dividido em dois blocos. O primeiro investiga a questão do critério utilizado para selecionar o método de melhor desempenho na tarefa de interpolar a curva de juros brasileira em uma dada amostra. Foi proposto um critério de seleção de método baseado em estratégias de re-amostragem do tipo leave-k-out cross validation, onde K k £ £ 1 e K é função do número de contratos observados a cada curva da amostra. Especificidades do problema reduzem o esforço computacional requerido, tornando o critério factível. A amostra tem freqüência diária: janeiro de 1997 a fevereiro de 2001. O critério proposto apontou o spline cúbico natural -utilizado com método de ajuste perfeito aos dados - como o método de melhor desempenho. Considerando a precisão de negociação, este spline mostrou-se não viesado. A análise quantitativa de seu desempenho identificou, contudo, heterocedasticidades nos erros simulados. A partir da especificação da variância condicional destes erros e de algumas hipóteses, foi proposto um esquema de intervalo de segurança para a estimação de taxas de juros pelo spline cúbico natural, empregado como método de ajuste perfeito aos dados. O backtest sugere que o esquema proposto é consistente, acomodando bem as hipóteses e aproximações envolvidas. O segundo bloco investiga a estimação da curva de juros norte-americana construída a partir dos contratos de swaps de taxas de juros dólar-Libor pela Máquina de Vetores Suporte (MVS), parte do corpo da Teoria do Aprendizado Estatístico. A pesquisa em MVS tem obtido importantes avanços teóricos, embora ainda sejam escassas as implementações em problemas reais de regressão. A MVS possui características atrativas para a modelagem de curva de juros: é capaz de introduzir já na estimação informações a priori sobre o formato da curva e sobre aspectos da formação das taxas e liquidez de cada um dos contratos a partir dos quais ela é construída. Estas últimas são quantificadas pelo bid-ask spread (BAS) de cada contrato. A formulação básica da MVS é alterada para assimilar diferentes valores do BAS sem que as propriedades dela sejam perdidas. É dada especial atenção ao levantamento de informação a priori para seleção dos parâmetros da MVS a partir do formato típico da curva. A amostra tem freqüência diária: março de 1997 a abril de 2001. Os desempenhos fora da amostra de diversas especificações da MVS foram confrontados com aqueles de outros métodos de estimação. A MVS foi o método que melhor controlou o trade- off entre viés e variância dos erros. / [en] This thesis investigates interest rates curve estimation under non-parametric approach. The text is divided into two parts. The first one focus on which criterion to use to select the best performance method in the task of interpolating Brazilian interest rate curve. A selection criterion is proposed to measure out-of-sample performance by combining resample strategies leave-k-out cross validation applied upon the whole sample curves, where K k £ £ 1 and K is function of observed contract number in each curve. Some particularities reduce substantially the required computational effort, making the proposed criterion feasible. The data sample range is daily, from January 1997 to February 2001. The proposed criterion selected natural cubic spline, used as data perfect-fitting estimation method. Considering the trade rate precision, the spline is non-biased. However, quantitative analysis of performance determinant factors showed the existence of out-of-sample error heteroskedasticities. From a conditional variance specification of these errors, a security interval scheme is proposed for interest rate generated by perfect-fitting natural cubic spline. A backtest showed that the proposed security interval is consistent, accommodating the evolved assumptions and approximations. The second part estimate US free-for-floating interest rate swap contract curve by using Support Vector Machine (SVM), a method derived from Statistical Learning Theory. The SVM research has got important theoretical results, however the number of implementation on real regression problems is low. SVM has some attractive characteristics for interest rates curves modeling: it has the ability to introduce already in its estimation process a priori information about curve shape and about liquidity and price formation aspects of the contracts that generate the curve. The last information set is quantified by the bid-ask spread. The basic SVM formulation is changed in order to be able to incorporate the different values for bid-ask spreads, without losing its properties. Great attention is given to the question of how to extract a priori information from swap curve typical shape to be used in MVS parameter selection. The data sample range is daily, from March 1997 to April 2001. The out-of-sample performances of different SVM specifications are faced with others method performances. SVM got the better control of trade- off between bias and variance of out-of-sample errors.

L'objectif de cette thèse est d'analyser le système juridique français et brésilien concernant les stratégies de défense contre les offres publiques d'acquisition visant à prendre le contrôle des sociétés cotées en bourse. Les offres publiques d'acquisition font l'objet d'un vif débat, plus particulièrement lorsqu'elles présentent un caractère hostile pour la société cible. En France, de nombreux efforts législatifs ont été mis en œuvre en vue d'encadrer les OPA et de lutter contre les prises de contrôle rampantes. L'analyse du droit positif permet de mettre en lumière ces différents efforts ainsi que leur mise en œuvre à travers diverses techniques par les sociétés visées. Grâce à l'analyse juridique des stratégies anti-OPA en France, le système brésilien peut prendre connaissance de cette expérience et trouver la meilleure approche juridique pour les sociétés cotées ayant un capital flottant important. Au Brésil, la récente vague d'IPO a été possible grâce à la réforme dans la bourse BM&FBOVESPA. Dorénavant, la BM&FBOVESPA présente le scénario idéal pour prendre le contrôle des sociétés cotées. Ainsi, l'importance de ce thème est le résultat de la dispersion de l'actionnariat après la première vague d'introduction en bourse dans le marché de capitaux brésilien, et en France, elle se traduit par l'évolution dans environnement légal des défenses anti-OPA face à des pratiques qui ne cessent d'évoluer. / The objective of this thesis is to analyse the French experience and the Brazilian legal environment concerning the defense strategies against hostile corporate takeovers aimed at taking control over public companies. Through the analysis of the French legal system of the anti-takeover strategies, the Brazilian system will be able to acquire this experience and find the best legal approach for Brazilian public companies with dispersed ownership. The importance of this theme is the result of the ownership dispersion following the first IPOs in the current Brazilian securities exchange market, which provides the ideal scenario for taking control of these publicly-traded companies, as well as the changes and the evolution in the French legal environment.
