Sous l’angle des controverses économiques et environnementales autour des hydrocarbures non conventionnels, cette thèse contribue au développement des outils de la modélisation intégrée sous deux aspects : leur capacité à représenter la dynamique de long terme des marchés de l’énergie ; la prise en compte des liens entre l’économie et la dynamique des différents gaz à effet de serre.Dans le premier cas, un jeu de simulations avec le modèle Imaclim-R met en évidence les impacts économiques du gaz et pétrole de schiste à travers (i) les liens entre trajectoires de crois-sance et inerties techniques ; (ii) la conditionnalité des gains de compétitivité des États-Unis aux stratégies implicites ou explicites de ce pays en matière de spécialisation internationale et de régime de change. Au détour de ces simulations nous étudions (α) les processus d’ajustement vers l’équilibre de long terme, en regardant les conditions d’obtention et de convergence des équilibres temporaires du modèle ; (β) les limites de tractabilitéd’une maquette stylisée du modèle reproduisant les mécanismes centraux.Dans le deuxième cas est traitée la question du rôle du méthane à court et long terme dans les stratégies climatiques. L’intégration du modèle réduit du système terrestre Oscar2.2 aumodèle Imaclim-R permet d’apprécier le rôle du méthane dans les coûts de l’atténuation et d’évaluer le risque d’émissions fugitives en tête de puits de gaz de schiste. Les simulations montrent que d’une part, l’avantage économique de la disponibilité en gaz de schiste peut être nuancé au regard du coût induit par ces émissions fugitives. D’autre part, les stratégies climatiques ambitieuses visant à limiter les augmentations de température bien en deçà de 2° voir 1.5°C nécessitent un contrôle plus immédiat des émissions de méthane. / From the perspective of economic and environmental controversies over unconventional oil and gas resources, this thesis contributes to the development of integrated modelling tools intwo aspects : their ability to reflect the long-term dynamics of energy markets ; and the consideration of the links between the economy and the dynamics of the various greenhouse gases.In the first case, a set of simulations with the Imaclim-R model highlights the economic impacts of shale gas and light tight oil through (i) the links between growth paths and technicalinertia ; (ii) the conditionality of US competitiveness gains on implicit or explained strategies ; and (iii) the conditionality of US competitiveness gains on this country implicit or explicit strategies in terms of international specialization and exchange rate regime. In the course of these simulations, we study (α) the adjustment processes towards the long-term equilibrium, looking at the conditions of existence and convergence of the model temporary equilibria ; (β) the tractability limits of a stylized model of Imaclim-R reproducing the main mechanisms.In the second case, the question of the role of methane in short and long term climate strategies is addressed. The integration of the Oscar2.2 Earth System model into the Imaclim-Rmodel is used to assess the role of methane in terms of mitigation costs and to assess the risk of emissions leakage at shale gas wellheads. The simulations show that, on the one hand, theeconomic advantage of shale gas availability can be balanced against the costs induced by these emissions leakage. On the other hand, the ambitous climate strategies aiming at limitingtemperature increases well below 2° or 1.5°C require a more instant control of methane.

The walk of quilombolas and the formation of the urban quilombo. Doctorate Thesis on Social Sciences, presented at the Pontifícia Universidade Católica de São Paulo (PUC). São Paulo, March of 2005. This dissertation studies the descendants of quilombolas from two communities in the Zona da Mata Mineira: Colônia do Paiol, which beginnings are from the second half of the 18 th Century, through the donation of lands made by the farmer José Ribeiro Nunes, according to his own will registered at the Public Archives of the Court of the City of Barbacena, Minas Gerais; the second community is Bias Fortes, founded at the first half of the 18 th Century, through a quilombo of fugitives slaves and of migrants that later populated the area. For this purpose, the author contextualizes historically the meaning and the evolution of the presence of slaves in the lands of Minas Gerais, since the ends of the 17 th Century, within the black during the golden cycle. It is remarked that slavery in Brazil was not homogeneous: it depended on the economic cycle, on its moment, on the region and on the times. In this frame, quilombos are worthy of special attention, studying the mechanisms that gave them birth, specially the letters of freedom (cartas de alforria) and the escapes, studying as well the geographic and social situation of the quilombos towards the whole society of the time, as well as the ways of control and repression perpetrated by the colonial establishment against them. Trough the register of oral reports and narratives of members from these communities, the author reconstitutes the genesis, summarizes the historical development, rememorizes the facts and the people who lived them, investigates the migration moviments and their destination, forward to, at last, establishing a parallel between the past and the present of these populations of quilombolas which origins were Bias Fortes and Colônia do Paiol and who migrated to Juiz de Fora. / SILVA, Djalma Antônio da.

Esta tese estuda os remanescentes de quilombos de duas comunidades da Zona da Mata Mineira: Colônia do Paiol, cuja origem data da segunda metade do século XVIII, com nove ex-escravos do fazendeiro José Ribeiro Nunes, que lhes doou as terras, conforme testamento constante no Arquivo Público do Fórum de Barbacena, Minas Gerais.

Para tanto, contextualiza-se historicamente o significado e a evolução da presença de escravos em terras mineiras, a partir do final do século XVII, com o tráfico negreiro dirigido sobretudo à exploração do ouro durante todo o seu ciclo. Destaca-se que a escravidão no Brasil não foi homogenia: dependia do ciclo econômico, do seu momento, da região, da época. Nesse quadro, os quilombos merecem especial atenção, estudando-lhes os mecanismos originantes, tais como as alforrias e as fugas, bem como a situação geográfica e social em relação à sociedade da época, e as formas de controle e repressão usadas pelo establishement colonial contra eles. Através do registro de relatos e narrativas orais de membros dessas comunidades, reconstitui-se a gênese, traça-se o desenvolvimento histórico, rememoram-se os fatos e as pessoas que os protagonizaram, investigam-se as movimentações migratórias e seus destinos para, enfim, estabelecer-se um paralelo entre o passado e o presente dessas populações de quilombolas cuja origem foram Bias Fortes e Colônia do Paiol e que migraram para Juiz de Fora.

The purpose of this thesis is to introduce a musical work of one of the world's most favorite composers of the 20th century - Sergej Prokofiev. Even though I would like to address all his pieces, given the extensiveness of his work and my profession as a pianist and a pedagogue, I decided to focus only on the pieces for solo piano. I detail each piano piece in a catalogue organized by opus number. My analysis focuses on compositions, eventually on cycles, which can be somehow beneficial to us. Beneficial, in this sense means exposure to pieces with variety of character, use of melody and eventually pieces from a various work periods. Another condition during a selection of pieces for my dissertation was various levels of difficulty. The majority of my thesis is dedicated to the piano sonatas. Although they are not very long, they belong to the piano masterpieces forever. Further, I mention less performed Etudes, Op. 2 and Visions fugitives, Op. 22, and on the other hand well known Suit from Romeo and Juliet, Op. 75. The music for children is represented in my analysis by one piece only - Children's Songs, Op. 65. Prokofiev wrote nearly 40 opuses for piano, which makes up almost a third of his work. That is a remarkable number and these pieces are worth interest.
