L’ouverture de l’économie colombienne, décidée en 1990, fut présentée comme un promoteur de croissance et développement sur la base des exportations (et des Investissements Directs Etrangers). Cette thèse soutient que l’ouverture n’a pas été décidée afin de favoriser la croissance et le développement et que ces deux phénomènes n’ont pas été à la hauteur de ce qui était anticipé. Ce résultat est fondé sur une analyse en termes d’Economie Politique Internationale : les relations de pouvoir peuvent être utiles pour répondre à des questions d’ordre économique. Le premier chapitre montre que les caractéristiques structurelles de l’économie colombienne rendaient son ouverture impropre à générer croissance et développement sur la base des exportations. Cette proposition s’appuie sur l’analyse de la compétitivité sectorielle et des carences institutionnelles de l’économie colombienne, ainsi que sur l’accroissement potentiel des inégalités spatiales de développement suite à l’ouverture. Le deuxième chapitre s’attache alors à mettre en évidence que l’ouverture répond à des objectifs propres aux Etats-Unis. Ces objectifs sont à dominante économique (typiquement la création des débouchés extérieurs et l’accès à des matières premières) ou politique (lutte contre les guérillas d’inspiration communiste dans le cadre de la politique étrangère américaine). Le deuxième chapitre expose une série des moyens à la disposition des Etats-Unis afin d’obtenir l’ouverture du gouvernement colombien de l’époque. Ces moyens vont de la coercition (par exemple la menace de sanction) à la légitimation (favoriser l’élection d’un gouvernement pro-ouverture). Le troisième chapitre montre que l’ouverture n’a pas instauré un régime de croissance fondé sur les exportations. Au contraire, elle a instauré un régime instable fondé sur une dynamique spéculative sur les actifs immobiliers à partir des flux de capitaux étrangers venant nourrir l’achat de ces actifs à crédit. Lorsque ces capitaux finissent tôt ou tard par manquer, de tels achats sont pénalisés et viennent interrompre la dynamique. Celle-ci ne peut plus tirer la croissance via des effets d’entrainement du secteur de la construction sur le reste de l’économie. Mais pris au piège de la relation de pouvoir exercée par les Etats-Unis, le gouvernement colombien n’a pas cherché à stabiliser la conjoncture. Il a dû privilégier les dépenses en équipement militaire américain pour lutter contre les guérillas colombiennes. L’intensification subséquente du conflit armé a accentué la violence au sein du territoire. Il en résulta la destruction d’infrastructures, ainsi qu’une migration de travailleurs qualifiés. La récession en a été d’autant plus accentuée. Ainsi l’ouverture débouche-t-elle sur la pire crise économique du XXème siècle en Colombie, avec une récession de -5% en 1999. Le quatrième chapitre enquête sur les changements des structures de production et d’échange suite à l’ouverture, pour ainsi montrer que ces changements n’ont que peu favorisé le développement. La Colombie tend à négliger sa spécialisation internationale historique dans le café et la plupart des cultures transitoires (blé, riz, orge, sorgo, coton, etc.) pour privilégier d’autres cultures dont les effets positifs sur le développement sont moindres. Bien que les hydrocarbures et d’autres matières brutes bénéficient d’un certain potentiel d’exportation, le développement des territoires où l’extraction a lieu reste faible. Se pose en outre un problème de soutenabilité de l’extraction. Enfin, si l’industrie manufacturière a pu croitre au rythme du régime de croissance, elle le doit à la protection dont elle bénéficie encore dans le cadre du traitement différentiel des pays en développement à l’Organisation Mondiale du Commerce et moins aux opportunités d’exportation données par l’ouverture. Le jour où ce traitement sera diminué voire supprimé, toute une partie de l’économie colombienne est menacée. / The opening of the Colombian economy, decided in 1990, was supposed to promote a new model of growth and development based on exports (and Foreign Direct Investment). This dissertation argues that the opening was not made in order to promote growth and development, and that these two phenomena did not live up to what was expected. This result is based on an International Political Economy approach: taking into account power relationships may give a better explanation of economic phenomena. The first chapter shows that the structural characteristics of the Colombian economy made its opening unable to generate growth and development. This assertion is based on the analysis of the lack of competitiveness and of the institutional flaws of the Colombian economy, as well as on the potential increase in the spatial inequalities of development resulting from the opening. The second chapter thus highlights that the opening aimed at achieving some objectives peculiar to the United States. These objectives are made of economic considerations (typically the access to foreign markets and to raw materials) as well as political ones (dealing with the threats caused by Marxist guerrilla groups within the framework of the American foreign policy). This second chapter explains a series of means at the disposal of the United States to obtain the opening. These means go from coercion (such as sanction threats) to legitimation (to give rise to a Colombian pro-opening government). The third chapter shows that the opening did not lead to an export-led growth. On the contrary, it led to an unstable growth regime. The latter is based on the foreign capital flows. The latter feed the purchase of real estate assets by credit. The housing sector is thus stimulated, which in turn stimulates other economic activities, within the framework of spill-over effects. However, when foreign capital flows lack, real-estate asset purchases are penalized, thus preventing the expansion of the housing sector and eventually of aggregate production itself (spill-over effects no longer work). However, given the power relationship exercised by the United States, the Colombian government had to purchase American military equipment massively, in order to fight against the Colombian guerrillas. By doing so, the economic policy could not stabilize the economy at that time. Besides, the subsequent intensification of the conflict increased the violence within the Colombian territory, thus leading to the migration of skilled workers and to the destruction of infrastructures. The recession had thus been exacerbated. This scenario occurred a few years after 1990, resulting in the worst economic crisis of the 20th century in Colombia with a -5 % recession in 1999. The fourth chapter questions the changes followed by the production and exchange structures because of the opening, to show that these changes did not really contribute to development. Colombia tends to neglect its historic international specialization in coffee and other cultures like wheat, rice, barley, sorghum or cotton, to privilege other cultures whose positive effects on development are lower. As regards the industries of extraction of raw materials (in particular hydrocarbons), they are oriented toward exportation but they promote few development. In addition, the Colombian productive system may lack of this type of input in the future. Finally, if the manufacturing industry was able to increase at the rate of the growth regime, it owes it to the protection still remaining with the differential treatment for developing countries in the World Trade Organization, and less to the export opportunities given by the opening. When this treatment will be eliminated or at least decreased, a whole part of the Colombian economy will be threatened.

This study examined the metaphors used in contemporary American conservative discourse between October 2018 and March 2019, focusing on material published by conservative think tanks (CTTs) and tweets made by Republican senators in relation to climate change. For the CTTs, a domain-specific corpus (36,388 words) was compiled and a smaller corpus (3967 words) was assembled based on 135 tweets. These datasets showed that conspiracy scepticism was the most common type of scepticism used to discredit climate change data, scientists and environmental policies. In addition, the datasets indicate that conservative agents frequently used metaphors of WAR, RELIGION, HEALTH, BUILDING, JOURNEY, WATER and PRODUCT to convey negative frames. These domains linked to the conceptual key LIFE IS A STRUGGLE FOR SURVIVAL and were presented in a moral context. In response to these findings it is suggested that the scientific community incorporate emotional language, metaphors and moral values when communicating environmental issues.

Este trabalho, organizado sob a forma de dois artigos, faz uma análise da evolução da agropecuária do Brasil e dos EUA, respectivamente, de 1986 a 2004 e de 1960 a 2001, dando destaque à análise econométrica das principais variáveis que determinam a participação da agropecuária no PIB. Os EUA, no período de 1973 a 2001, apresentaram uma tendência decrescente da participação da agropecuária no PIB, e o Brasil apresentou este comportamento de 1986 a 1993, revertendo a tendência de 1993 a 2004, contrariando a tendência mundial apresentada na literatura. Por meio de gráficos, verifica-se o crescimento da produção física da agropecuária do Brasil e dos EUA para os respectivos períodos, com grande crescimento da produtividade total dos fatores. Esta última, nos EUA, se associa com a presença de subsídios governamentais à agropecuária. Para o caso brasileiro, o crescimento da participação da agropecuária no PIB ocorreu com grande influência da elevação da relação de preços recebidos/preços pagos, variável que apresentou comportamento descendente no caso dos EUA. Baseado em um modelo contábil que explicita as variáveis que determinam a participação da agropecuária no PIB, um modelo econométrico é definido e estimado para ambos os países. Constata-se que as principais variáveis determinantes da participação da agropecuária no PIB (em ordem decrescente), para o Brasil, no período de 1993 a 2004, são: a produtividade da indústria, a razão preços recebidos/ preços pagos pela agropecuária, a produtividade da agropecuária e a participação defasada da agropecuária no PIB; e para os EUA, no período de 1973 a 2001, são: a relação de preços recebidos/ preços pagos pela agropecuária, o valor defasado dessa participação e a Produtividade Total dos Fatores - PTF da agropecuária. / Organized in two papers, this dissertation analyzes the evolution of agriculture in the Brazil and the USA from 1986 to 2004 and from 1960 to 2001, respectively. Special attention is paid to an econometric analysis of the main variables that determine the participation of agriculture in the Brazilian and the US agriculture. From 1973 to 2001, agriculture had a downward trend in the US gross domestic product (GDP). The same trend had happened in Brazil from 1986 to 1993, but it reversed from 1993 to 2004, what is clearly different from the worldwide trend. Dataset organized in graphs show a steady increase of physical production in both Brazilian and US agricultures during the time periods above mentioned, followed by the increase of total factor productivity. The latter at the USA is closely related to the grants of Federal subsidies. The enlargement of received prices/paid prices ratio in Brazil play an important role in the growth of agriculture\'s participation in the GDP, while the downward trend of this variable at the USA helps to explain the decrease of agriculture\'s participation in the US GDP. An accounting model is developed to diagnose the main variables that determine the agriculture\'s participation in a country\'s GDP and an econometric model is derived from this accounting model. Running the econometric model to Brazil from 1993 to 2004, the main variables determining the agriculture\'s participation in the GDP (counting down) are: industrial productivity, received/paid prices ratio, agriculture productivity and lagged value of agriculture\'s participation in the GDP. The same analysis to the USA, using dataset from 1973 to 2001, shows the main variables to be: received/paid prices ratio, lagged value of agriculture\'s participation in the GDP and total factor productivity of agriculture.

Esta dissertação tem como objetivo central discutir a importância do Atlântico Sul para os Estados Unidos da América, a partir da análise das suas políticas de segurança cooperativa para a parcela sul do Oceano Atlântico considerando, principalmente, seus determinantes internos e a própria ressignificação da região entre os anos de 2003 e 2014. Ela se enquadra nas Resoluções nº 114/2014 e 115/2014 da Câmara de Pós-Graduação da UFRGS e, portanto, é dividida em três capítulos, correspondendo a três partes distintas. O Primeiro Capítulo é desenvolvido em três etapas: Primeiro, relaciona o contexto da dissertação na linha de pesquisa “Segurança Internacional” do PPGEEI/UFRGS. Segundo, aborda alguns elementos das políticas externa e de segurança dos EUA, a importância do mar para a condução dessas políticas e uma breve contextualização do Atlântico Sul. Terceiro, ressalta os principais pontos analíticos e considerações desenvolvidos no capítulo seguinte. O Segundo Capítulo traz o artigo publicado na Revista da Escola de Guerra Naval que conduz, primeiro, uma breve discussão de alguns conceitos teóricos importantes para entender a postura dos Estados Unidos na condução de sua política externa e de segurança, recorrendo ao debate da influência da política interna nas suas relações internacionais. Em seguida, discute brevemente a importância do "uso do mar" para a política externa dos EUA, contextualizando o Atlântico Sul como uma região estratégica, discutindo suas fronteiras geográficas, aspectos econômicos e organizações multilaterais. Finalmente, discute alguns dos programas norte-americanos de segurança cooperativa para o Atlântico Sul e a crescente importância da região, em linha com o novo posicionamento estratégico pós-11 de setembro. O Capitulo três faz uma breve análise dos resultados do artigo e também apresenta agendas de pesquisas possíveis de serem conduzias no PPGEEI. Foi verificada a importância do artigo para trazer a discussão da segurança cooperativa, pelo viés estadunidense, no âmbito da pesquisa no PPG e também para fomentar a visibilidade deste problema nos fóruns de discussão e leitores do periódico científico de sua publicação. Assim,foram cumpridos os objetivos de discutir a importância do Atlântico Sul para os Estados Unidos da América, a partir da discussão das políticas de segurança cooperativa, dos determinantes políticos internos e da mudança da relevância da região para a grande estratégia norte-americana. Inferindo então, a pertinência do Atlântico Sul, evidenciada pela busca de iniciativas de segurança colaborativa e combate às ameaças de baixa intensidade, visando conter novas ameaças e enfrentar atores não estatais. / The present dissertation aims to discuss the importance of the South Atlantic to the United States of America, from the analysis of its cooperative security policies for the southern part of the Atlantic Ocean, considering mainly its internal determinants and the re-signification of the region between the years of 2003 and 2014. It is in accordance with Resolutions 114/2014 and 115/2014 of the Universidade Federal do Rio Grande do Sul, and therefore comprises three chapters, corresponding to three distinct parts. Chapter One presents three steps: First, it relates the context of the dissertation in the research line "International Security" of the Post-Graduate Program in International Strategic Studies. Second, it addresses some elements of the U.S. foreign and security policy, the importance of the sea for the conduct of these policies and a brief contextualization of the South Atlantic. Third, it highlights the main analytical points and considerations that developed in the next chapter. Chapter Two brings the article published in the Revista da Escola de Guerra Naval which leads, firstly to, a brief discussion of some important theoretical concepts to understand the U.S. position in the conduct of its foreign and security policy, using the debate of the U.S. internal policy on their international relations. Then, briefly discusses the importance of "use of the sea" for U.S. foreign policy, contextualizing the South Atlantic as a strategic region, discussing its geographical boundaries, economic aspects, and multilateral organizations. Finally, discuss some North American cooperative security programs for the South Atlantic and the region's growing importance, in line with the new strategic post-9/11 position. Chapter Three brings a brief analysis of the paper's impacts and presents possibilities of investigation agendas to follow on PPGEEI. Therefore, it was possible to verify that the article was important to bring the discussion of cooperative security, by the American bias, in the African region to the scope of the research in the PGP and to promote the visibility of this problem in the discussion forums and readers of the scientific journal of its publication, fulfilling its objectives of discussing the importance of the South Atlantic to the United States of America, from the discussion of the cooperative security policies for the African West Coast, through the internal political determinants and the change of the region relevance to the global north American grand strategy. Inferring then, the relevance of the South Atlantic in this grand strategy, evidenced by the search for collaborative security initiatives and to combat low intensity threats such as piracy, aiming to contain new threats and face non-state actors.

Este trabalho analisa a trajetória da assistência dos Estados Unidos da América à Colômbia para o combate às drogas a partir de 2002. Considerando o histórico de aproximação entre os dois países relativa a políticas sobre drogas, pretende-se explicar o motivo da diminuição da assistência antidrogas dos Estados Unidos à Colômbia no final da década de 2000. A hipótese deste estudo assinala que esta diminuição é explicada devido à posse de Barack Hussein Obama como presidente dos Estados Unidos, em 2009, e às alterações da política externa da Colômbia com a eleição do novo presidente Juan Manuel Santos Calderón, em 2010. Com efeito, houve diminuição considerável do poder das Forças Armadas Revolucionárias da Colômbia (FARC) após o Plano Colômbia, facilitando a abertura dos diálogos de paz e seu tratamento menos militarizado nos mandatos de Santos e Obama. Neste trabalho, são apresentados um histórico do combate às drogas e aos grupos insurgentes, além das principais diretrizes da Polícia Externa da Colômbia e suas relações com os Estados Unidos. Ademais, são expostos os dados referentes à assistência policial, militar, humanitária e econômica estadunidense à Colômbia para o combate às drogas, as agências norte-americanas de fomento à assistência internacional, os acordos bilaterais vigentes entre estes países, bem como a legislação que rege o repasse de recursos norte-americanos ao exterior. / This paper intends to present the trajectory of U.S. assistance to Colombia in regards to drug fighting from the year of 2002. Considering the historical alignment between these two countries concerning drug policies, this study intends to explain the reason behind the decrease in counternarcotics assistance provided by the USA to Colombia at the end of 2000s decade. The hypothesis of this work suggests that the reduction in counternarcotics assistance is resulting from the beginning of the American presidential term of Barack Hussein Obama in 2009, and the change in Colombian foreign policy with the new president Juan Manuel Santos Calderón in 2010. In fact, the power of Revolutionary Armed Forces of Colombia (FARC) decreased after Plan Colombia, hence it enabled the beginning of peace talks and its less militarized treatment during Santos and Obama terms. In this work, the history of the fight against drugs and insurgent groups will be discussed, as well as the main guidelines followed by the Colombian Foreign Policy, and its relations with the USA. Additionally, it will be present data on the United States military, police, humanitarian and economic assistance used to combat the drug problem in Colombia, and information on American agencies that promote international assistance. Further information on the bilateral agreements between these countries, as well as legislations that allow American resources abroad will be discussed.

O presente trabalho tem por objetivo analisar a forma épica na peça We, the People, escrita pelo dramaturgo norte-americano Elmer Rice [1892-1967]. Essa peça, composta por vinte cenas e mais de quarenta personagens, foi escrita em 1932 e encenada em 1933, nos Estados Unidos, dentro de um dos períodos mais conturbados da história norte-americana: a Grande Depressão [1929 até o final dos anos 1930]. Pretende-se analisar a esfera formal de We, the People, dedicando particular atenção aos recursos empregados para a representação de questões sócio-históricas. Considerando-se que essas questões não são representáveis enquanto tais por meio da estrutura dramática convencional, e que pertencem ao âmbito formal do épico, o trabalho tratará de examinar e discutir o uso de recursos épicos de concepção dramatúrgica e seus efeitos dentro da peça. / This work aims at analyzing the epic form in the play We, the People written by the American playwright Elmer Rice [1892-1967]. This play is composed of twenty scenes and more than forty characters; it was written in 1932 and presented in 1933 in the United States of America during one of the most troubled period of the American history: the Great Depression [1929 end of the 1930s]. We intend to analyze the formal aspects of We, the People focusing mostly on the expedients used to represent socio-historical issues. Considering that these issues cannot be represented by using the conventional dramatic structure and that they belong to the epic form, this work will examine and debate the use of epic theater expedients and its effects in the play.

In its theoretical part this master thesis identifies the main criteria determinating a diasporic ethnic group, based on publications from the scholarly journal Diaspora: A Journal of Transnational Studies. Further on the master thesis deals with the history of the Jewish diaspora, firstly with the worldwide Jewish diaspora and subsequently with the Jewish diaspora in the United States . The further part of the master thesis concerns a more specific determination of the Jewish diaspora in the United States -- the history, structure and influence of the Jewish lobby in the United States. The last part supports with illustrative examples the influence of the Jewish lobby on the United States foreign policy on the US economic and military aid to Israel in particular.

A tese busca apresentar uma explicação para a formulação da política externa norte-americana para a República Popular da China, a partir da disputa de grupos de interesse doméstico por espaço nessa política. Essa disputa tem por locus o Congresso dos EUA. Das formas de relação entre os grupos domésticos e os membros do Legislativo, o trabalho elege o financiamento de campanhas eleitorais combinado com os perfis político-ideológicos dos congressistas. Destes, são examinados os que introduziram propostas levadas à votação em plenário, nas duas casas legislativas. São também verificados os resultados dessas propostas em plenário. A combinação do financiamento de campanha com o perfil político-ideológico permite o estabelecimento de categorias de identificação desses congressistas. As categorias apontam para a aceitação ou a rejeição das relações sino-norte-americanas. Com base nessas categorias, é verificada a inclinação à cooperação da política externa dos EUA para a República Popular da China. / This thesis aims to present a explaining to the formulation of the U.S. Policy toward People´s Republic of China, from the dispute of interest domestic groups for a room in this Policy. Dispute has locus on the U. S. Congress. From kinds of relations among domestic groups and members of the Legislative, this work chooses elections campaigns financing combined with the politic-ideological side view of the members of the Congress. Among these are investigated sponsors and cosponsors responsible for introduce proposes for roll call at plenary assemblies of both Legislative Houses. Vote results are examined too. The arrangement of elections campaigns financing with politic-ideological side view allows the institution of identification categories of the members. These categories point toward acceptance or rejection of the US-China relations. Based at these categories, is determined the tendency to cooperation for the US policy toward China.

Historiquement, les États-Unis ont, dans l’ensemble, accordé assez peu d’importance au Maghreb, les dirigeants américains considérant que celui-ci faisait partie de la zone d’influence de l’Europe, notamment de la France. La Seconde Guerre mondiale, la décolonisation dans les années 1950 et 1960 et, enfin, le conflit du Sahara occidental jusqu’aux années 1980 sont les périodes au cours desquelles la présence américaine dans cette région a été la plus active. Le Maghreb n’a pas été tenu à l’écart des enjeux et défis du monde dans les années 1990. Comment les Administrations Bush et Clinton se sont-elles comportées face à des régimes autoritaires, socialement fragilisés par un endettement endémique et incapables de construire un projet alternatif au plébiscite populaire dont jouissent les partis islamistes ? Parmi les déterminants internes de la politique étrangère américaine, quels sont les principaux acteurs liés au Maghreb ? Quels ont été les rôles du Congrès, des partis politiques, des diplomates, de la presse dans les positionnements américains face à la montée en puissance de l’islam en tant que force dans la région ? Existe-t-il des intérêts liés à des camps politiques et économiques américains au Maghreb ? Existe-t-il des courants antagonistes au sein du Congrès et de l’exécutif américains au sujet de la politique à mener dans cette région ? / In history, United States did not focus on North African issues. American leaders consider that this part of the world is under European influence, especially under French influence. The Second World War, decolonization in the 1950s and 1960s and the Western Sahara dispute in the 1980s are the periods during which American presence has been the most active. Yet, the Maghreb was not kept out the stakes and challenges facing the world in the 1990s. How did the Bush and Clinton Administrations consider the North African authoritarian regimes, socially weakened by endemic debts and unable to provide an alternative response to the popular call for Islamist parties ? In the making of American foreign policy, which actors are bound to the Maghreb region ? Which roles played the Congress, the media, the political parties as the Maghreb faced the booming of Islam as a political force ? Are there any interests of American parties or American political and economic clans in the Maghreb ? Are there any antagonist positions inside the Congress and the executive branch about the policy to conduct in the region ?
