Full textThe airport infrastructure has become the twenty-first century the pivot of flows crossing of people and goods in our "globalized" world, its constant evolution and particularly rapid since the mass air transportation, questions us on the subject "airport ", through its urban, architectural features and design in relation to its host city and its fate in the future. One of the significant aspects of the city airport is relationship and territorial confrontation between these two entities, it can lead in some contexts to obsolescence of the airport platform faced with urban expansion and the refusal by the infrastructure residents. This thesis did research on this phenomenon in the geographical framework of the Southern Cone of Latin America. It develops in a plane in three parts : a first analysis of the airport infrastructure of a global perspective in order to characterize its territorial dimensions and recent developments in relation to the host city. It seeks to identify examples of obsolescence airport in the northern hemisphere. The second part focuses on capital cities of the Southern Cone of Latin America and their airports, by detecting cases of actual or future obsolescence, this on two fronts, Atlantic and Pacific, whose geomorphological features are totally different. Finally a third part examines the future of airport infrastructure which tend to become mega-airports and conjuring obsolescence. These considerable scales are not necessarily adapted to the developing countries of the Southern Cone of Latin America. Is there an intermediate size transforming the airport into something other than a gigantic machine to manage flows? Can it be that the airport platform becomes a complex of buildings seeking a harmonic relationship with the city that surrounds it ?

Full textAfter a period of french linguistic and cultural influence observed at the turn of the century, in spanish-speaking argentina, chile paraguay and uruguay, due to important migratory movements and an inflatuation of the local elite for french culture, a period of decline came in the early seventies. French lycees, alliances francaises, french teachers, french language policies, reciprocal images and representations between south america and france, and alternative markets will be studied. A renewal in the promotion of french could be structured around three points: first the intercultural option and the relationship to "the other", then a new internal and external institutional communication, finally a reinforced presence in the audiovisual media

Full textThe thesis will focus on the influence of public international law on transitional justice in the Southern Cone of Latin America and in Spain. The function of transitional justice is to deal with the criminal past of a state within the framework of a democratic transition. It is based on three main rights: truth, justice, reparation. The aim is to show the role of international conventions in reactivating the judicial process relating to human rights violations perpetrated by military regimes in Argentina, Chile and Uruguay. Latin America was inspired by the Spanish democratic transition. This was based on forgetting the dictatorship in the name of national reconciliation. This pattern had been reproduced in the Latin American Southern Cone. Consequently, the action of justice had been blocked by the laws of amnesties approved during democratic transitions during the 1980s. During the 1990s, public international law produced conventions incriminating the acts committed by these dictatorships, in particular enforced disappearance. Consequently, in Latin America, the Constitutions have been revised to give a preponderant place to international standards for a better guarantee of fundamental rights in order to avoid a return to authoritarianism and arbitrariness. Thus, the treatment of the criminal past by the vector of international law encountered highlights its place within the Constitution.International law, via constitutional law, becomes the main vehicle for reactivating the judicial process. Moreover, the Spanish democratictransition based on the forgetting of the Franco's dictatorship is called into question through the experiences of transitional justice in Latin America, looks like Argentina

Full textArgentinean hydrocarbur networks have lived a huge restructuration, after the State reform in the 90's. Activities de-regulation and the privatization of YPF and Gas del Estado forced the sector re-concentration, since then dominated by foreign companies, leaded by Repsol YPF. The hydrocarburs federalization contributed to the weakening and uncapitalization loss of wealth of the State. These changes resulted in an increase of the hydrocarburs production allowing to achieve the self-supply. Nevertheless, the expansion of internal networks has not been large enough to ensure the coverage of new requirements. Besides, several infrastructures have been built up to join external markets. National networks are connected to those of near neighboring countries. This integration is an opportunity for the "South Cone" countries to enhance their potentials. In the country, hydrocarbur territories undergo the restructuration effects (unemployment, loss of territorial identity, etc). With many difficulties and very different possibilities, those territories, like Comodoro Rivadavia, Ensenada et and Bahía Blanca, look for their re-invention

Full textThis thesis focuses on changes that took place in the teaching of Spanish and Portuguese as foreign languages in the education systems of Brazil, Argentina and Uruguay during the so-called Golden Decade spanning approximately from 2003 to 2012. Measures like the Law 11.161/2005 in Brazil, which compelled high schools to offer Spanish as an optional subject; the Law 26.468/2009 in Argentina, which established the same requirement for Portuguese; and the Law 18.437/2008 in Uruguay, which recognises Portuguese-based dialects spoken in the north of the country, imply a historical transformation of the relationship between these two Iberian languages, which had thus far been characterised by mutual marginality in school systems. However, the projects embodied in these laws clash with several budgetary, logistic, ideological and geopolitical realities which compromise their final achievement. Throughout this work we will try to identify which actors, forces and obstacles align around these languages in these three countries. Based on standard theoretical schemes integrating the notion of Language Planning, we propose a three-plane model where corpus, status and gravitation will allow us to apprehend the specificities of this case study: No other pair of languages in the world presents this level of both intelligibility and sociolinguistic importance, and never before had a generalised reciprocal teaching of them been so seriously attempted. Therefore this inquiry will focus on : (1) How does the fact that they are closely related languages determine determine their glottopolitical relationship and their insertion into education systems; (2) Which discourses accompany these and other foreign languages taught in schools and which political projects do they represent; (3) What are their internal gravitational characteristics, their projection and for which languages do they show preference in their translation flows. We thus hope to draw valid conclusions on gravitational vicissitudes of Spanish and Portuguese, as well as to shed some light on the challenges faced and resources found by supercentral languages in their quest for international spaces.This analysis shoud allow a better characterisation of the dichotomy between two models of linguistic globalisation: hypercentralist and supercentralist. One is unipolar, with English as the hegemonic language and supercentral languages relegated to local levels; the other is pluripolar, with these languages sharing their international presence under a prevailing glottopolitical horizontality

Full textA French naval surgeon, Jules Crevaux made several journeys to South America, including four exploration trips in the Guianas, Amazonia and Orinoco areas between 1869 and 1882 before he was slain by the Gran Chaco Indians in Bolivia. He came to prominence through the widespread reports of his travels, backed by the Geography Society and the « Tour du Monde » magazine. His reports have definitely changed the image of the Amazonian area from the conventional Eldorado to « locus terribilis ». Crevaux occupies an uncommon place in his time for his almost humanistic approach and his eclectic intellectual curiosity. This work aims at enhancing and enlightning the figure of the late 19th century explorer in the days of European expansionism. It gives a detailed account of the staging of the journey while probing into the motivations of the explorer and the reception after his return. It also shows the evolution of historiography which had sunk into oblivion until a revival of interest since the 1980's. The work should also help to gain a better understanding of the consequences of the annexation of Alsace-Lorraine to Germany which had such a decisive impact on Crevaux's attraction to exploration trips. A protagonist in the 1870 war along with Gambetta, he subsequently received support from the Ministry of Public Instruction especially in Ferry's days. At a time when French foreign policy was mainly focused on Africa and South East Asia, this work aims at showing why South America suddenly aroused widespread curiosity and why a Lorraine born geographer choosing to keep the French nationality fostered this nascent interest

Full textOften reduced to the better-known corrida de toros or bullfighting, tauromachy includes a great diversity of practices in Southwestern Europe and Latin America. Whatever are the tauromachy practices under consideration, professional or not, festivals and bulls are always associated in the stages of the regions. This systematic relation, which requires a cautious examination, can be interpreted as the tauromachy's adaptation to the stakes and functioning of contemporary societies. Moreover, on every stage tauromachy practices find a way to define and differentiate itself from the others. Tauromachy then acts as a powerful territorial marker on various scales and contributes to identify, delimit and differentiate a cultural area under Hispanic influence. The chosen approach to study this phenomenon can be seen as being part of a more general investigation on territoriality
La tauromaquia suele ser confundida con la sola corrida de toros mientras que abarca en realidad una gran variedad de prácticas que se desarrollan en el Sur de Europa como en Latinoamerica. Tener en cuenta al mismo tiempo la totalidad del espacio taurino y el conjunto de sus prácticas permite subrayar las interacciones entre las distintas culturas taurinas. Las prácticas taurinas forman un sistema tal y como las identidades sociales y territoriales que expresan. A partir de ahí podemos estudiar el papel y la importancia que tiene la tauromaquía en la construcción de las identidades locales, regionales, y/o nacionales de las sociedades aficionadas y sobre todo podemos entender las relaciones que existen o no entre estos distintos niveles de identificación. Este analisis sale de una pregunta : ¿ cuales son los mecanismos sociales y espaciales que hacen de la tauromaquía un potente medio de construcción identitaria y territorial ? Dicha pregunta se situa en una reflexión general sobre el funcionamiento de la territorialidad

Full textSoutheastern South America (SESA) is one of the few subtropical regions where WCRP/CMIP3 coupled general circulation models project significant summer rainfall increases by the end of the twenty first century, in a global warming scenario. This signal is revealed to be associated with a frequency increase of positive phase of the leading pattern of austral summer rainfall variability in the region. The positive phase manifests as austral summer rainfall above (below) normal in the SESA (South Atlantic convergence zone) region. Moreover, the rainfall pattern change is shown to be associated with positive anomalies of the sea surface temperature (SST) in the equatorial Pacific. This result is confirmed by numerical sensitivity experiments performed with the LMDZ4 " two-way nesting " interactive climate models system, which also showed that the projected rainfall increase in SESA is mainly associated to the zonally asymmetric pattern of the tropical SST warming

Full textThe biotic link between Africa and South America has always fascinated scientists. With the advent of plate tectonics, this link could now be explained via a series of vicariance events i. E. The rupture of continental landmasses. However, molecular data have changed our ideas on the relative role of vicariance. Under a vicariant model, dates for taxon divergence should coincide with geological dates however, in the case of Africa and South America, the incorporation of a time scale in molecular analyses point to another explication. Dispersal, formerly considered a random process not able to produce clear patterns, is now seen as an playing an important role in producing biogeographical disjunctions. The expectation would be that marine and wind currents between Africa and South America have heavily influenced angiosperm biogeography between the two continents. In this thesis, we collate a maximal amount of molecular data for 38 angiosperm famillies with disjunctions between Africa and South America. We then infer from their phylogenies using probabilistic methods, the direction of dispersal events and we evaluate the correlation between the directions and the predominant marine and wind currents. Results are then examined taking into account their ecologies. A prelimanry stusy was also erformed on the order Malpighiales to estimate dates of divergence for several families posessing disjunctions between the two continents. We evaluate the frequency with which dispersal events between the continents have occured during the Tertiary

Full textWhen information became an important tool for the development of capitalism in the 19th century, international news agencies looked for new territories to expand their business. Through a Joint Purse Agreement, the Reuter’s Telegram Compagny (1851) of London and the Havas Agency (1832) of Paris decided to go together to South America. They were able to accomplish their wishes when the transatlantic cable linking Europe to the South American continent was finally laid down between Brazil and London. As this joint venture ends by 1876, Havas could finally foresee a monopoly of the South American market till the end of the First World War. Based on a thorough research on company and diplomatic archives, this dissertation contributes to the history of news agencies. By dividing the period of study in three phases, each one enhancing one aspect of this information exploitation (the installment strategies, the human components and the rivalry produced by other, local or international, news agencies) this dissertation concludes the partial loss of the French monopoly in the region

Full textThis thesis intends to think philosophically the problem of the subject through the subject of human rights in the context of the dictatorships and post-dictatorships of the Southern Cone of America. It analyses, more specifically, the dialectical relationship between the forms of state terrorism (especially systematic and massive violations) and the forms of the subjectivity of human rights and of the subject in general. Such a task requires the revision of different aspects of the same problem : the object human rights as such, the theories of the subject, the dictatorships and democratic transitions of the Southern Cone, the philosophical formulation of systematic and massive violations of human rights under the category of " radical evil " and the different ways of deconstructing and constructing the past and the future through the " solutions " given to the problems posed, the creations produced and the roads opened and in particular the projection of the possibilities offered to human rights and through it, to the " theory " of the subject in a transitional world

Full textThis study, in the field of both public international law and environmental law, deals with the concept of "shared natural resources" and its application in the joint management of water resources, especially among south American countries. "shared natural resources" is a concept established in the seventies, and was used in various bilateral and multilateral treaties, particularly those concerning the production of hydroelectric power. Some treaties are analyzed, as well as the united nations environmental program draft principles concerning the harmonious utilization of shared natural resources, and the international law commission draft project on the law concerning the utilization of international rivers. The study is divided in two parts. The first one deals with water as a "shared resource", that is, the evolution of the juridical approach of international rives and the problems arising from a fragmented perception of water resources. The second part studies, in a more pragmatic way, the application of the concept in the joint management of the plata and amazon basins. It also presents the use of the concept in other parts of the world (especially in the Rio Grande and Mekong basins) and in the field of resources other than water (straddling resources and resources above national jurisdictions)

It has been taken into consideration the circumstances in each states´ period of independence and formation, and the lack of results in the process of integration in the XIX and XX centuries. The previous issues have been analyzed within a framework of various theories that refer to integration processes and to the regional development of the European Union. The configuration of sub-national spaces in Colombia has also been analyzed, as well as the development of regional cross-border spaces with neighboring countries, issues that, accompanied with infrastructural improvement, will result in the construction of new Latin American and South American transnational spaces, supporting the region’s development

Like other Argentine provinces, Mendoza has had to adjust to the imposed new rules, trying to make its best from its resources. This thesis analyze the territorial transformations taking place in Mendoza province since the last years of the 80's to the firsts of the new century, analyzing how endogenous and external factors have been combined and revealing the social and spatial consequences of these transformations. To do so, some dynamic axes of these transformations are analyzed: the transition from the traditional wine industry to the "new wine industry", recent initiatives around transportation and energy networks crossing national borders and changes in the Metropolitan Area of Mendoza

Full textThis petrogenetical study was carried out on Tertiary magmatic rocks outcropping in central Chile at 33°S, the aim is establish their origin and age. The study region is composed for balsatic/gabbroic to andesitic/dioritic lithologies (>90%), Their U-Pb ages vary between 28,1 and 11,5 Ma and they evidence a continuous period of ~16,6 Ma of cacalkaline magmatism. The initial isotopic ratios shows narrow margins of variation and they show no chronological variations. The Pb vary between 18,358 and 19,023 for 206Pb/204Pb, between 15,567 and 15,700 for 207Pb/204Pb, and 38,249 and 39,084 for 208Pb/204Pb. The (87Sr/86Sr) ratio varies between 0,70369 et 0,70505, except for two more radiogenic values equal to 0,7066. The εHfi value varies between +6,9 and +9,6. These initial isotopic signatures obtained lying on the referential field of the subcontinental mantle. The εHfi signature permitted to calculate a model age of formation for this mantle source equal to ~2 Ga, which would have evolved with time-integrated ratios Rb/Sr and 238U/234Pb of 0,039 and ~16 respectively. These magmas would have undergone a low degree of crustal contamination (5% maximum). The εNdi and εHfi signatures both previously and here reported are characterized by : (1) a positive ΔεHfi signature ; and (2) a narrow spatial coherence with the time-integrated evolution calculated for perioditic Andean xenoliths. These characteristics suggest that these εNdi and εHfi signatures are representative of a subcontinetal lithospheric mantle source generated towards 2 Ga ago and then (~1,5 Ga) it was metasomatized through diverse additions form an E-MORB source

Full textThe aim of this thesis is to better understand the processes at the origin of the evolution and present-day topography of the Fitz Roy region, located in the Southern Andes, at the border between Chile and Argentina (49°S). This region is characterized by a particular geodynamic context that may play a major role on surface processes. Indeed, the Chile Ridge separating the Nazca and Antarctic oceanic plates, is being subducted beneath the South American plate since 14 My. The obliquity between the ridge and the subduction trench is responsible for a continuous northward migration of the triple junction that is located today at 46°30’S. Furthermore, the Southern Andes is covered by the 3rd largest ice sheet, that constitutes the relict of a much broader glacier formed during the late Miocene. Nowadays, Patagonia is affected by a strong climatic contrast, with a semi-arid climate on the eastern side chain, while the core and the western side of the chain are covered by glaciers and subject to strong precipitations. The tectonic/climatic setting is unique in the world and constitutes a natural laboratory to study of the interactions between ridge subduction, regional tectonics and climatic conditions on topographic evolution through time.To explore the impact of spreading ridge subduction on the overlying continental plate, analogue modeling of subduction of a ridge were conducted. The models highlight direct effects on the geometry of the slab et thus on the position of the magmatic arc. The arrival of the spreading ridge at trench, when the overriding plate moves rapidly trenchwards, induces a decrease of the superficial dip of the slab. This flattening results in an increase of the distance between the trench and the magmatic arc, prior to the ridge subduction. The eastwards migration of the magmatic arc is consistent with the observed magmatic activity migration in Patagonia during the early Miocene, a few million years before the arrival of the Chile Ridge at trench around 14 My. These models also suggest that the subduction of the ridge induces a horizontal shortening of the overriding plate, as observed in Patagonia during the early-middle Miocene. Shortening ceases when the ridge subducts.To explore the role and of tectonic and climate (glaciation) on the topography and exhumation rates, thermochronological data have been acquired in two localities: the Fitz Roy granitic massif, emplaced during the lower Miocene around 16,5 My at a depth of about 8 km and the overlying Cretaceous sandstones located to the East. Apatite fission track data (AFT) from granites provides a mean signal of 14,8 My. This suggests that the pluton cooled rapidly after its intrusion below 110 °C. The signal obtained in sandstones is younger at 12,5 My. We suggest that the fast denudation is related to the arrival of the ridge at trench and precedes its subduction, which take places at about 12 My at the latitude 49°S. Although we have not been able to constrain the exact timing of shortening in the fold and thrust belt, related to ridge subduction. We suggest that this deformation related to the ridge subduction may have ceased between the lower and the middle Miocene, based on other studies realized to the North and to the South of our study area.The (U-Th)/He data in apatite (AHe) present a signal between 7 and 6 My, that highlights the effect of the first glaciations of Patagonia that induced an acceleration of the relief denudation. We suggest that glacial erosion play a major role on the topography and relief denudation during the late Miocene. Glaciers of Patagonia at the latitude 49°S did not have a protector role of the relief, as suggested by Thomson et al. (2010).To conclude, evolution of relief in Patagonia is the result of both tectonic and climatic processes. In our study area, at a 49°S latitude, the effect of each process has been highlighted because they are not contemporaneous but separated by about 6 to 7 My

Full textThe research developped has as main objective tha analisis, comprehension and isolation of regularities of state's interventions in latin america during tha last thirty years as well as the preview of tha possible scenaries that could result from the xxith century's transformations. This has required the identification of significant periods: the industrial poles stategy of the 70's, the industrial relocalisation in the 80's deceny crise and the recent perod of integration policies. The most significant cases studied are exemples in the south cone and in mexico, where we have studied and worked over the las twenty years: salto grande hidroelectrial projet in argentina, the nuclear and electrical production in atucha i and ii; industrial promotion policies, specialised territories, atlantic-pacific bioceanic strategy. The approach to this subject is centered in the relationship between the power system evolution and space production

Full textThe overseas expansion and circulation of new products between the New and Old World are one of the great issues for the historiography that is dedicated to the Atlantic trade and to the global commerce. While specialists have been working on this issue with regard to the insertion, adaptation and consumption of these new genres in America, Europe, Asia and Africa, there has been little discussion about the agents who have promoted this movement around the globe: specialized traders - druggists - and their trading companies. This thesis presents an interconnected history between those who provided products for the medical market in Europe and Portuguese America and the ways in which new medicines were introduced by global commerce in the second half of the 18th century. Its main objective is to provide an analytical overview for the understanding of processes that have been mutually global and local, for example: how did an Amerindian medicine become a medicine certified and guaranteed by European or Asian medicine? And how were these products introduced in these circuits and by what market routes?

Full textThe objective of the present work is to characterize sediment supply dynamics within the Plio-Pleistocene Corinth Rift using an integrated approach based on field observations and analyses, experimental modeling and numerical modeling. Detailed sedimentological, structural and biostratigraphical studies on the southern coast of the rift provide a tectono-stratigraphic model within a well-constrained climatic and eustatic setting. Stratigraphic simulations (DIONISOS) are used to validate this model, to quantify the sediment supply and to discuss the relative role of four controlling factors on stratigraphic architecture (sediment flux, water flux, subsidence, eustasy). Finally, a geomorphological experimental approach has been developed to study the relative role of factors (rainfall, uplift rate. . . . . ) that control sediment supply and their record within the sedimentary signal

Full textCes changements ont entraîné une augmentation de la production d'hydrocarbures, permettant d'atteindre l'autosuffisance et d'exporter. Mais l'expansion insuffisante des réseaux internes semble compromettre la couverture de nouvelles demandes. En revanche, des réseaux d'oléoducs et gazoducs ont été réalisés pour atteindre les marchés externes. Les réseaux argentins s'intègrent à ceux des pays voisins. Cette intégration offre aux pays du Cône Sud une opportunité de mettre en valeur leurs potentiels.
A l'intérieur du pays, les territoires des hydrocarbures font face aux conséquences de la restructuration (chômage, perte d'identité territoriale...). Avec difficulté et des possibilités très différentes, ces territoires, tels Comodoro Rivadavia, Ensenada et Bahía Blanca, cherchent à se réinventer.

Full textMarta Traba (1923-1983), an Argentinian-Colombian writer and art critic, is most famous in Latin America for her critiques, her commitment to develop modern art in Colombia, and, more generally, for her “theory of resistance” which advocates the defence of the many cultural Latin-American identities in fine arts. Her literary work, however, is far less well-known. And yet, not only is it very rich, but it also constitutes the narrative counterpart to her critiques – a collection of tales innervated, to different degrees, with Traba’s notions on and knowledge of art. It is consequently about reconsidering these two sides of her written production as a consistent whole, and identifying the influences and interactions between her art critiques and her literary work, as well as between the fine arts which make up her artistic culture and her fictional writings.It then appears that Marta Traba devises and practices her critical writing “literarily” as she does, above all, her literary work “artistically”: the constant enhancement of the aesthetic eye on the world and of an intensified sensory experience shape an ideal of contemplation throughout her literary work; the continuous inserts of a critical terminology and of references to art works, sometimes in a clearly didactic mode, sometimes in a subtly playful manner, invite the reader to read her fiction stories and poems in the light of the artistic subtext which enriches their meaning; finally, the tale becomes the place where Traba’s theories of “resistance” are tested, at the crossroads of the re-affirmation of the place of Latin America on the map of international art, of the defensive distancing from North American influences, and of the local re-appropriation, by “transculturation”, of the foreign artistic models. The study of the artistic mutation of Traba’s literary work is therefore far from boiling down to the analysis of a mere formal process: from our point of view, it reveals an authentic style, Traba’s style, which is the mirror of the writer and her convictions

Full textOur thesis is a comparative analysis that focuses on rhythm as a parameter. The corpus of study consists of forty of the most iconic music genres of South America. The main issue is to understand the relationship between the structure of the rhythms and their various vernacular names and to make their cultural meaning emerge. The goal of our analysis is to create typological alternatives that confront the observation plans (endogenous and exogenous). These typologies focus on the family similarities between the rhythms and their possible affiliations. This analysis is based on various transcription processes, modeling and comparison of polyrhythmic patterns. Several aspects and components relating to the rhythmic parameter will also be considered, such as timbre oppositions, tempo, multiple performance formulations, and agogic principles created by the musicians. Consisting of four chapters, our thesis is based on several methodological steps: our music analysis and our initial typological proposals (exogenous perspective) on one hand, and on the other hand, our investigation process lead with the owners of the traditions (endogenous perspective). Both perspectives are then related, or faced, all in the perspective of a cultural validation.
