Full textIn the interface of the sociology of migration and political sociology, the thesis focuses on return migration of Congolese refugees from the main host countries of central Africa. Far from being observed in a linear and static perspective between two sedentarinesses but analyzed starting from in situ observations and from biographical interviews conducted during 16 months in host and return areas, the migrations of return are integrated in a dynamic migratory space constituted by oppositions and transactions between the biopolitic plans of retention of flows and the circulatory practices of the refugees. The accent is particularly focused on negotiating "biographical crossroads" and migratory careers of refugees from the social, spatial and political capital acquired during the refuge time. How, in these intersections between migratory careers and biopolitical plans, the returnees can define and negotiate their installations in the environment of return ?

Full textBetween 1930 and 1970 brazzaville and leopoldville (actually kinshasa) reciprocally influenced one another, and these influences spanned several domains. In the economic world these two cities, the two closest capitals in the world geographically speaking, played complementary roles. Leopoldvlle, economic capital of congolese africa, attracted a great number of brazzavillians due to industrial density within the city. In cultural and social spheres the two cities consisted of a unique theater with innovative behaviors. Through sports, music and cultural associations the young congolese tried to alger the colonial power structure and to take over the "city of whites. " noticeably between 1954 and 1956 the brazzaville congolese exerted a considerable influence within the political realm over the march towards the decolonization of the belgian-congo. With the independences and the opposed ideological choices, one awaited the birth of new solidarities and new evolutions in which the ethnic phenomenons continued to be the deciding factor. Today, brazzaville and kinshasa continue to live in their tight "vicinity of influence" : for better or worse. .

Full textThis dissertation is presenting a linguistic classification based on phylogenetic methods borrowed from biology. The sample of languages considered here belongs to the Bantu family, a linguistic sub branch of Niger-Congo languages spoken in Africa. Numerous publications have shown a complexity and the diversity of Bantu languages. Our study focus on the North-West region which includes the following countries: Cameroon, Equatorial Guinea, Gabon, Congo and Democratic Republic of Congo. This new classification is based on the comparison of lexical items. We have organized a database including 100 words from the basic vocabulary for 207 languages. Several tree representations were obtained by using Neighbor-Joining (Saitou and Nei, 1987) and Neighbor-Net (Bryant and Moulton, 2004) algorithms.This study allows us to get a better understanding of the linguistic proximity of these languages. It also provides a historical scenario for Bantu migrations

Full textEvidence of fluid flow features and their mechanisms of migration through the sedimentary pile are a known phenomenon on continental margins. It has been widely studied over the past twenty years, notably due to the improved resolution of seismic data and the abundance of data in these areas due to oil and gas exploration.The Lower Congo basin, offshore West Africa, is a prolific petroleum province that has been extensively studied, and has been in operation for over 30 years. The area of interest is located above a producing oil field (the Moho license), in which hydrocarbons are trapped in turbidite channels. The work is primarily based on the analysis of geophysical data including 3D and 2D-THR seismic, multibeam bathymetry and corresponding backscatter, as well as background data (samples taken from ROV photos, geochemical analyses).The analysis of this important seismic dataset revealed abundant evidence of fluid migration in the Mio-Pliocene sedimentary pile. They mainly correspond to indications of vertically focused migration, including current fluid expulsion structures on the seafloor, and buried structures, interpreted as fossile and indicating former activity of the fluid expulsion system. The studied fluid migration features mainly consist of pockmarks (depressions) and carbonate cementations. These two types of indicators can build vertical stacks, over several hundred meters, highlighting the durability of the fluid escapes and suggesting the development of real pipes.A new type of pockmarks has been discovered, the spider structures, which are located above a turbiditic reservoir, and which result from a focused migration of thermogenic hydrocarbons. They are related to gas hydrates, in the context of a sloping BSR (Bottom Simulating Reflector), due to the presence of the hydrate wedge. A dynamic model of their functioning is proposed, showing that these structures develop upslope, due to the gas migration under the sloping BSR. A study of the BSR, in the particular context of the hydrates wedge, allows to propose a model of gas escapes, linked to the dissociation of the hydrates, during a sea level fall. This model presents a dissociation of gas hydrates of regional scale (associated with biogenic gas), localized at the gas hydrate wedge zone of the last lowstand. Finally, the network of fluid escape structures of the Mio-Pliocene interval was investigated in order to understand its architecture and the mechanisms of fluid migration in the study area. Hydrocarbons appear to migrate mainly along certain portions of faults and vertically crosscutting the sedimentary pile through pipes or chimneys. The base of the Pliocene, associated with a sea level fall, marks the formation of the first paleo-spiders, as well as a level containing numerous evidence of gas. A model of this network of fluid migrations is proposed, integrating the indicators of hydrocarbon migrations through the sedimentary pile, and the major event of the Pliocene base. This study seems to indicate that a the sea level fall constitute a trigger for the fluids migrations, in the basin.This work thus marks the starting point of a larger-scale investigation which consists in, on the one hand, searching for similar structures (spiders and bands of pockmarks) in other basins ; and, on the other hand, by comparing fluid flow events with the eustatic curve

Full textSand intrusions (or injectites) are most often the product of post-depositional remobilization of sand leading to its injection into the surrounding rocks. While injectites were recognized for the first time nearly 200 years ago, their emplacement process has been studied for a couple of decades only, since the concepts of deep sea depositional environments have allowed us to better understand their emplacement processes. However, these processes are still relatively poorly understood. Our approach is based on the study of injectites in the Lower Congo Basin from seismic and well data, which we compare to a fossil system in the SE France basin. We have shown that:(1) In buried turbidite channel systems draping deposits on the channel flanks and terraces of channels have the same geophysical signature as ‘wing-like' injectites. Finally, the only criterion for identifying seismic injectites is the presence of bedding-discordant seismic reflections, and in the best case the associated uplift of the overlying seismic reflectors.(2) Seismic-scale conical and saucer-shaped sand injectites have been identified in the Lower Congo Basin. The remobilization is likely due to overpressuring induced by the buoyancy effect of hydrocarbons trapped in the margins of a lobe buried underneath 160 m of sediment, followed by the sudden injection of fluidized sand associated with fault reactivation of faults (with a possible role of nearby salt diapirs).(3) A network of injectites (dykes, sills/wings and laccoliths) was formed in the Vocontian basin during the late Albian and/or early Cenomanian, from a lower-middle Albian turbidite channel. The emplacement is probably due to the early compartmentalization of the channel during its burial and the increase of the sedimentation rate generating overpressure; and the subsequent large influx of deep fluids triggering injection. The injection of sand was polyphased: a first episode formed the sills and another emplaced the dykes. Sills/wings and dykes propagated about 2 km laterally away from the parent sand body and about 200 m up to the surface, revealing a much more extended lateral than vertical reach, contrary to the classically accepted idea from the interpretation of seismic data.(4) The emplacement of this large network of injectites was governed by hydrofracturing. Therefore, its morphology is dependent on the host rock heterogeneity (isotropy, fractures), the paleo-stress orientation (σ3 = NW-SE) and the burial depth of the source (300-600 m) at the time of injection. The study of this fossil network allows us to define the relationship between morphology of the injected network and stress state at the time of injection. This relationship can be extrapolated to constrain the morphology of subsurface networks beyond seismic visibility.(5) Sands injected into low permeability lithologies bear evidence to a major event of fluid escape in the studied basin, but also channeled fluids long after their formation. In this way, injectites both attest to specific episodes of fluid migration in sedimentary basins and contribute to long-lived re-routing of migrating fluids once emplaced.The injection of sand is associated with the sudden escape of fluids, probably resulting from a significant tectonic and/or sedimentary event; in addition, the architecture of injectite networks is governed by the local paleo-stress and heterogeneity in the host rock. Consequently, characterizing injectite networks is an important step in understanding the plumbing systems of continental margins, i.e. the post-depositional evolution of sedimentary basins

Full textThe numerous studies on forced migration often focused attention on the existential conditions of refugees and the many "social disruption" that characterize their exile. Whether in camps or in the outskirts of major cities in Africa and Europe, which some have called "non-places", they are often presented as the "edge of the world." Without denying these realities, it should however put this table, showing that refugees know mobilize resources that enable them not only to overcome the vagaries of exile, but also to build social ties in relation to the situations that arise to them. Taking up against the allegations about the lack of social ties refugees, this work therefore seeks to examine how, from how positive or negative, Congolese refugees build social ties not only among themselves but also with indigenous and state and international institutions, in Libreville, Gabon. It is in an interactional perspective, with contributions from fields such as history, sociology, psychology and political science, to understand the overall structure of the bond that unites them. Two schemes organize the reports of the three categories of actors. When the scheme "Congolese refugees' structure links between Congolese exiles, the scheme" parents enemies "meanwhile, organizes the relations between them, the State and indigenous peoples. These two schemas are thus "sociable dispositions"("binders") in situation

Full textAt the end of the Second World War, Koreans constituted the main foreign community in Japan. Many of them were subjected to discrimination, and lived precariously or even in abject poverty. From the latter half of the 1950s, when North Korean leaders were welcoming them and guaranteeing them decent living conditions, repatriation to North Korea represented hope for a better future for many of these Koreans. Between 1959 and 1984, more than 93,000 people – of whom 2,000 were Japanese women married to Koreans – arrived at the 38th Parallel North. Nevertheless, the Japanese government, confronted by requests from the families of these Japanese women from 1974, tried to obtain information on their whereabouts, and asked for their return to Japan. The present work establishes a mapping of the actors implicated in the decision-Making process concerning repatriation operations to North Korea, but also in the negotiations retated to the Japanese women. More specifically, this study highlights the role of the “subsidiary actors” – of which the Japanese Red Cross and national parliaments are the most prominent – those that intervened where the government’s margins for manoeuvring were narrow in the absence of official diplomatic relations between Japan and North Korea. This institutional constraint led to an investment in fields of action that had traditionally been relegated to the Ministry of Foreign Affairs (negotiation, protection of nationals abroad, intelligence, etc.) by these “subsidiary actors”, and a subsequent analysis of these actors provided both a more complete and less state-Centred image of Japan’s foreign policy
