No. of bitstreams: 1 PDF - Hugo Gabriel Lima Nascimento.pdf: 43389476 bytes, checksum: 35039fd2c5e7d497920f6b657852cbf1 (MD5) Previous issue date: 2015-06-03 / CAPES / International relations between Brazil and France, with regard to the border region, have been outlined during the 1990s, having greater intensification in 1996, due to the signing of the framework agreement, which was attended by state representatives of the countries mentioned above. That agreement led to the emergence of several initiatives in the field of cross-border cooperation, such as the proposed construction of a binational bridge over the Oiapoqueriver, Amapá (Brazil), linking French Guiana (France). Thus, the present study aims to investigate the role represented by the binational bridge on a new dynamic setting of cross-border cooperation between Brazil and France". The bridge is situated on the Oiapoqueriver, in Amazonian border region, between the cities Oiapoque, Amapá, and Saint Georges de L'oyapock, French Guiana. In terms of research methodology, this bibliographic study, which was conducted survey of official documents (reports, agreements, presidential speeches, interviews, among others) from France and Brazil related to border area in focus. The relevance of this work lies in the fact that allow reflection on the Amazon, seen as strategic political and diplomatic relations between Brazil and France, on the South American scenario. The survey results indicate that the bridge, completed in 2011, has not yet opened, favored the emergence of new possibilities of interaction and physical union in the southern cone countries, which in turn can enable the consolidation of relations between both countries, bringing development to the border area. / As relações internacionais entre Brasil e França, no que se refere à cooperação trasnfronteiriça, foram delineadas ao longo da década de 1990, tendo maior intensificação em 1996, devido à assinatura do Acordo-Quadro, que contou com representantes de Estado dos países supramencionados. Esse acordo propiciou o surgimento de várias iniciativas, como a proposta de construção de uma ponte binacional sobre o rio Oiapoque, ligando o Amapá (Brasil) à Guiana Francesa (França). Assim, o presente trabalho tem como objetivo geral investigar o papel representado pela ponte binacional, resultante da nova dinâmica de cooperação transfronteiriça entre Brasil e França. A referida ponte está situada sobre o rio Oiapoque, na região amazônica, entre as cidades Oiapoque, no Amapá, e Saint Georges de l’Oyapock, na Guiana Francesa. No que tange à metodologia da pesquisa, trata-se de estudo bibliográfico, por meio do qual foi realizado levantamento de documentos oficiais (relatórios, acordos, discurso presidencial, entrevistas, entre outros) da França e do Brasil relacionados à área em foco. A relevância deste trabalho reside no fato de permitir a reflexão sobre a Amazônia, vista como espaço estratégico das relações políticas e diplomáticas do Brasil e da França, no cenário sul-americano. Os resultados da pesquisa indicam que a ponte, concluída em 2011, mas ainda não inaugurada, favoreceu o surgimento de novas perspectivas de interação e união física no cone sul, que, por sua vez, podem permitir a consolidação das relações entre ambos os países, trazendo desenvolvimento para a zona fronteiriça.

Marquées par une histoire conflictuelle, les frontières de la Pologne ont connu depuis 1990 d’importants changements relatifs à leurs fonctions. Cette thèse se propose d’analyser les conséquences géopolitiques de ces changements sur les espaces frontaliers ainsi que sur le territoire polonais, au cours de l’intégration de la Pologne à l’Union européenne (UE), du début du processus d’adhésion à l’UE en 1998, à l’entrée complète dans l’espace Schengen en 2008. Ce travail revient dans un premier temps sur la dimension historique des frontières de la Pologne, caractérisées dans leur ensemble parleur grande instabilité. Ce retour en arrière nous permet de nous interroger, a posteriori, sur la spécificité des faits historiques qui ont marqué de façon durable l’espace polonais et ses frontières. Il propose ensuite une analyse comparative qui s’articule autour de la distinction typologique concernant le statut actuel des frontières polonaises : d’un côté les dyades internes de l’UE, frontières « en déconstruction » ; de l’autre les frontières « en reconstruction » sur les nouveaux confins de l’UE. Il tente enfin de faire la synthèse de ce « jeu des frontières » en analysant ses conséquences sur le territoire polonais. / Marked by a history of conflicts, the borders of Poland have experienced significant changes in their functions since 1990. This thesis aims to analyze the geopolitical consequences of these changes on the border area and the Polish territory, throughout the integration of Poland into the European Union (EU), from the beginning of the accession process in 1998, to its full membership in the Schengen area in 2008. At first, this work deals with the historic dimension of the borders of Poland, characterized by their high instability. This particularity allows us to retrospectively examine, the specificity of thehistorical facts that have durably affected the Polish space and its borders. Then this thesis provides a comparative and multiscalar analysis which revolves around the typological distinction regarding the status of Polish borders: the internal,« deconstructing » EU borders on one side, the new external « reconstructing » EU borders on the other. Finally, this work tries to analyze the effects of this « borders’ game » on the polish territory.

This article examines the securitisation of migration in the British-French border zone, based on applied practices to tackle migration. The border zone is characterised by measures, aiming to discourage people from staying in the area and crossing the border to the United Kingdom. Based on data obtained from semi-structured interviews and different textual documents, this thesis analysed whether practices applied in the border zone are “instruments of securitisation” and thus perpetuating the construction of migration as a security threat. Thereby the analysis was based on different criteria as put forward by the theoretical framework.  Ultimately, I argue that different measures, initially applied to tackle migration, do also perpetuate the securitisation of migration.

La fourmi d'Argentine (Linepithema humile) est une des espèces invasives parmi les plus nuisibles au monde. Dans le cadre des invasions biologiques, les résistances biotiques sont souvent les dernières barrières des écosystèmes. Une hypothèse, jamais testé in natura, de résistance de la part d'une fourmi du genre Tapinoma face à L. humile a été émise. Pour le démontrer, nous avons choisi d'expérimenter en laboratoire et in natura. Nos terrains d'études privilégiés ont été, outres des sites du littoral méditerranéen français, 4 îles situées en face du littoral envahi par la fourmi d'Argentine. Parmi celles-ci, deux contiennent à la fois la fourmi d'Argentine et des espèces du genre Tapinoma. L'identification difficile des espèces du genre Tapinoma étant sujette à une controverse scientifique, nous avons dû différencier de façon certaine cinq d'entre elles, par leurs morphologies et leurs signatures chimiques. En Provence, trois espèces ont été observées : T. erraticum, T. madeirense et T. nigerrimum. Sur l'île de Ratonneau, un suivi sur 2 ans de la vitesse d'invasion de L. humile en milieu naturel, avec ou sans T. nigerrimum, met en évidence une vitesse d'invasion très faible, voire un recul dans la zone à T. nigerrimum. Les colonies de T. nigerrimum de l'île de Ratonneau semblent faire obstacle à la progression de l'invasion. Des études comportementales préliminaires, conduites en laboratoire, entre fragments de nids de T. nigerrimum et L. humile nous avaient permis de confirmer les capacités de T. nigerrimum à résister face à l'invasive. Ainsi, les ouvrières T. nigerrimum défendent mieux leurs territoires, allant jusqu'à accaparer celui des L. humile. / The Argentine ant (Linepithema humile) is one of the world's worst invasive species. We used various analyses to determine its invasion pattern on the Provence coast, confirming the presence of a second supercolony. Chemical and behavioral analyses of worker interactions on the supercolony border identified a peaceful border zone. When biological invasion occurs, biotic resistance is often ecosystems' last defense. Could a dominant ant from Tapinoma genus resist L. humile invasion? To demonstrate this possibility, we conducted both laboratory and in natura experiements. Besides the invaded Mediterranean coast, we selected four nearby islands, two of which were found to contain both L. humile and Tapinoma spp. Identification of Mediterranean Tapinoma being controversial, we used both morphological and chemical analyses to ensure reliable discrimination. On the coast, we found T. erraticum, T. madeirense and T. nigerrimum. In natura, on Ratonneau Island, two-year field monitoring showed a slow rate of Argentine ant invasion and even retreat, faced with T. nigerrimum. T. nigerrimum colonies seem to block L. humile invasion. Laboratory behavioral studies between nests of T. nigerrimum and L. humile confirm T. nigerrimum's ability to stand up to Argentine ants: T. nigerrimum workers protect and defend their territories better, even taking over Argentine ant nests.

La fin de la Seconde Guerre mondiale, la guerre froide, la cohabitation pacifique, les mouvements d’indépendances, la fin du monde bipolaire, les crises multiformes et successives (culturelle, sociale économique et financière), voici autant d’événements qui ont changé les conceptions et la vision même du monde. L’initiative privée est à nouveau plébiscitée sur la scène mondiale. En effet, la rencontre entre le savoir-faire (financier et technique) du secteur privé et un secteur public ambitieux mais très limité, symbolisée dans le sigle « PPP », devient la formule gagnante.De nouveaux espaces font leurs apparitions, encouragées par le vent de l’intégration régionale et économique. Le mouvement de décentralisation propulsant celui de la coopération transfrontalière, nous assistons de plus en plus à une lente mais très prometteuse reconfiguration des dynamiques transfrontalières un peu partout dans le monde. Certaines régions offrent des perspectives très intéressantes, aussi bien sur le plan de la coopération transfrontalière que des PPP. C’est notamment le cas de la région francophone de l’Afrique des Grands Lacs. Cerner les PPP et la coopération transfrontalière, vérifier leur complémentarité et enfin suivre le mécanisme de réappropriation de ces deux concepts dans la région francophone de l’Afrique des Grands Lacs : voici les principaux objectifs que s’est assigné ce travail de recherche. / The end of the Second World War, the cold war, the peaceful cohabitation, the movements of independences, the bipolar end of the world, the multi-form and successive crises (cultural, social economic and financial), here is so many events which changed the designs and the vision of the world. The private initiative is again approved by a large majority on the world scene. Indeed, the meeting enters the know-how (financial and technical) of the private sector and the ambitious but very limited public sector, symbolized in the initials "PPP", becomes the winning formula.New spaces make their appearance encouraged by the wind of the regional and economic integration. The movement of decentralization propelling that of the cross-border cooperation, we assist more and more a slow but very promising reconfiguration of the cross-border dynamics almost everywhere in the world. Certain regions offer very interesting perspectives, as well from the point of view of the cross-border cooperation as the PPP. It is in particular the case of the French-speaking region of Africa of Great Lakes. Encircle the PPP and the cross-border cooperation, to check their complementarities and finally to follow the mechanism of reappropriation of these two concepts in the French-speaking region of Africa of Great Lakes: here are the main objectives that assigned this research work.
