This thesis explores the "Closed Housing Project" (CHP), a building type found in the Colombian capital of Bogota. Responding to Bogota's problem of insecurity, CHPs are groups of dwellings that are organised around, or within, outdoor communal grounds closed to the public and surveyed by an armed guard. / The CHP, however, is much more than gates and guns. Due to its enclosure, it is isolated from Bogota's troubled urban setting. As a result, the CHP has become a marketing phenomena packaged and promoted by developers as an escape from many of the social problems of living in Bogota. The consuming public has accepted this option and popular culture now perceives the CHP as a necessary and appealing way of life. / Mostly drawing from the Bogota architectural press, this study argues that the insular nature of the CHP makes a return to earlier housing types typically found in Bogota, and thus is evidence of architectural continuity in the city. The thesis also analyses the role of the CHP type in contemporary consumer culture.

Paragonimus spp. are parasites that infect many populations worldwide. It is predicted that infection rates within Asia reach ten to fifteen percent of the total population. Three largest areas of possible infection are Asia, Central and South America as well as Africa where the total population at risk is estimated to be 293 million people. Ingestion of raw or undercooked crustaceans are the source of infection to mammals. The crustaceans Neostrengeria macropa and Procambarus clarkii in Bogotá, Colombia were collected from local markets, pet stores and waterways. Dissection for presence of parasites is imperative to estimate the prevalence of crustacean infection by lung flukes. The preliminary findings show, pending laboratory confirmation, that the native crab species, N. macropa, has a prevalence of 17.2% infection. Invasive crayfish species, P. clarkii has a prevalence of 36.4% from both captive and field capture samples. While the prevalence estimated within this study is lower than compared to previous research in other cities of Colombia, there may be a number of factors that contribute to the difference in prevalence including: collecting season, overall low rainfall, temperature, altitude and the El Niño Southern Oscillation.

This thesis aims to describe in depth the Network of Provision Services to Public Space Users (REDEP), which is a new formalization program for street vendors in Bogota. The development of this study contributes to the research about street vending policies in Bogota, which have been studied little by the academy. To achieve a depth description of this program, this study approached three important aspects of the REDEP: the rationale behind its creation, its legitimation and its outcomes. In order to do this, this thesis has used Foucault’s concept of Discipline and the policy approach Aestheticization of Poverty described by Roy. In addition, Bogota’s street vending policies between 1990 and 2005 has been analyzed. Finally, 22 vendors working in REDEP’s kiosks and two officials working in REDEP’s management were interviewed. This thesis concludes that the creation of the REDEP has as main cause the negative perception of peddlers as threatening population to development of the Bogota as a “democratic” and ”equalitarian” city. Like other formalization initiatives, the program has aimed to formalize and discipline street vendors through the construction of kiosks and points of sale. REDEP’s outcomes according to vendor’s perceptions have not been completely positive in aspects like sales, working conditions and levels of participation.

This thesis describes a research project undertaken in a school located in a deprive neighbourhood of Bogota, the capital of Colombia. The project investigated the effects of musical experiences on social and musical development by means of a mixed methods approach involving children, parents, and teachers. The project comprises three studies: an experimental intervention study; and interviews study and a psycho-musicological study. The experimental intervention study was carried out with two groups of 52 children between six to eight years old; the experimental group followed a music programme of a singing workshop in which children made musical improvisations. The interviews study carried out interviews with the children, parent and teacher conducted during the intervention programme. The psycho-musicological case study analyse the musical improvisations of six of the children. Data analysis includes the statistical analysis of the children‘s tests (Harter´s Perceived Competence Scale for Children, 1999)and Self-Efficacy in Music, Hargreaves et al., 2002), qualitative analysis of parents‘, children‘s and teachers‘ interviews and a psycho-musicological analysis of children‘s musical improvisations (Ockelford, 2007) and its relation to children‘s cognitive and socio-emotional development. The principal findings are that the cognitive component of the self-identity of children who undertook the music programme increased. This appears to be related to the children‘s cultural environment, their parents‘ attitudes, and the idiosyncratic ways in which they use music to express themselves. Music appears to help them to be resilient, to manage the challenges they face, and to adapt to changes in the environment.

Fatores como o deslocamento forçado, as migrações e as poucas garantias de segurança e desenvolvimento econômico nas áreas rurais fazem piorar este processo de crescimento. Mais de 72% da população habita áreas urbanas de Bogotá, capital da Colômbia, conta com quase sete milhões de habitantes tornando-se cidade mais povoada do país e gerando uma grande demanda de moradia e serviços públicos que não são cobertos na totalidade. Esta investigação foi levada a cabo em cinco setores de Bogotá - em cinco estudos de caso onde a situação ambiental e social, somada ao crescimento urbano, constitui um cenário complexo. Estes estudos de caso mostram a situação dos mananciais, um setor dos morros orientais da cidade, evidenciando a progressiva invasão de moradia ilegal e seus efeitos sócios ambientais. / For some decades Bogotá has come experiencing a significant urban growth, factors like the forced displacement, the migrations and the few guarantees of security and economy in the rural areas, make worse this growth. More than 72% of populations are living in urban areas, in the case of Bogotá the capital of Colombia, this count with almost seven millions of inhabitants, becoming the populated city in the country, generating a great housing demand and public services that don't cover in their entirety. This investigation was carried out in five sectors of Bogotá city, with the interest of case studies, where the environmental and social situation, added to the urban growth, constitutes a complex scenario. These case studies show the situation of the natural lakes and one sector of the oriental hills of the city, evidencing the progressive invasion of illegal housing and their social and environmental effects.

La race est autant une catégorie sociale qu’une catégorie analytique, et cette dualité représente un défi pour les chercheurs et chercheuses qui s’intéressent aux rapports de pouvoir dans les sociétés racialisées. Afin d’étudier la reproduction et la contestation de la race dans l’ordre racial multiculturel en Colombie, je propose d’analyser les discours et la pratique d’acteurs sociaux qui, en interaction avec les institutions étatiques, contribuent à la reproduction et à la transformation de la race et des ordres raciaux dans lesquels ils s’insèrent. Je m’intéresse en particulier à l’entreprise identitaire des acteurs sociaux et politiques racisés qui participent à la reproduction ou à la transformation de l’ordre racial multiculturel. Ces acteurs, nombreux et variés, vont des leaders ethniques jusqu’aux chercheurs. Si tous ces acteurs peuvent être qualifiés d’entrepreneurs raciaux, cette thèse se concentre sur un groupe spécifique de jeunes Afrodescendant.e.s de Bogotá, pour une grande partie d’entre eux provenant des familles mixtes, ayant eu accès à l’Université, faisant l’expérience d’une ascension sociale et travaillant dans des domaines relatifs à la défense des droits de la population noire en Colombie. Je montrerai l’importance de ces facteurs dans leur identification en tant qu’Afrodescendant.e.s à travers l’analyse de leurs discours et de leurs processus identitaires. En même temps qu’ils en sont exclus, ils reproduisent et contestent le cadre multiculturel en élargissant la conception ethnicisée de la population noire à une conception directement liée à l’expérience historique du racisme et de la racisation, qui s’insère dans le contexte global de la diaspora africaine. Enfin, en ayant recours à l’approche intersectionnelle, à travers l’analyse des relations familiales et intimes des personnes enquêtées, je mettrai en évidence non seulement comment le privé devient politique mais également comment le politique imprègne le privé, afin de rendre compte de la place centrale du corps et de la blanchité dans le processus de racisation et dans les stratégies qui visent à défier celle-ci. / Race is as much social as an analytical category. Its duality represents a challenge for researchers interested in power relations within racialized societies. To study how race is simultaneously reproduced and contested in Colombia’s multicultural racial order, I set out to analyze social actors whose discourses and practices, in interaction with official institutions, contribute to reproduce and transform race and the racial orders within which they are embedded. My focus is on the identity entrepreneurship of racized social and political actors who participate in both the reproduction and transformation of the multicultural racial order. From ethnic leaders to researchers, these actors are many and diverse. Although they may all be described as racial entrepreneurs, this dissertation is centered on a specific group of young Afro-descendants from Bogotá, many of whom come from mixed-race families, are college-educated, are experiencing upward social mobility, and are working with black rights advocacy organizations in Colombia. I will show the importance of these factors for their identification as Afro-descendants through an analysis of their discourses and identity processes. They reproduce and contest the multicultural framework of which they are excluded by broadening the ethnic conception of the Black population to a conception that is directly linked to the historical experience of racism and racialization, one that is embedded within the global context of the African diaspora. Finally, by turning to an intersectional approach, through the analysis of their family and intimate relationships, I will demonstrate how privacy is politicized and politics privatized, to account for the central position of the body and of whiteness in both the racialization process and the strategies that aim at challenging it

A partir de l’évolution des écarts spatiaux des prix du logement et des prix fonciers entre sept secteurs de Bogota, entre 1970 et 2012, cette thèse analyse l’ampleur des recompositions socio-spatiales de la ville. En croisant l’analyse urbaine et l’étude de marchés immobiliers, cette recherche aborde l’évolution des secteurs déjà construits de la ville et les variations des prix des logements anciens. Contrairement aux recherches qui insistent sur la profondeur et la rapidité des transformations des villes latino-américaines sous l’effet de la globalisation, nos résultats montrent que les différences spatiales des prix du logement restent stables. Seuls les écarts spatiaux des prix fonciers augmentent pendant notre période d’étude. L’analyse statistique des facteurs explicatifs de l’inertie des écarts spatiaux des prix montre que la stabilité globale résulte de la conjonction de deux tendances ayant des effets opposés. La diffusion des commerces réduit les écarts spatiaux des prix, alors que la valeur symbolique du secteur de résidence explique le maintien des différences spatiales des prix. Quant aux prix fonciers, la densification des constructions explique une portion des écarts croissants entre secteurs de la ville, mais reste insuffisante pour comprendre l’ampleur des évolutions constatées / Following the evolution of the gaps in housing and land values between seven sectors of Bogotá between 1970 and 2012, this thesis analyzes the scale of urban socio-spatial transformations. By overlapping urban analysis with the study of real estate markets, this analysis deals with the evolution of already-built areas and their housing prices. In contrast with research that emphasizes the depth and rapidity of transformations in Latin American cities during globalization, our findings show that gaps in housing prices from one area to another remain stable. During the period studied, only in the realm of land value gaps in prices between one area and another did actually widen. The statistical analysis of factors explaining the stability of gaps between housing prices from one area to another reveals that overall stability results from the conjunction of two trends with opposite effects. The spatial diffusion of shopping outlets reduces the gaps in housing prices from one area to another, to the same extent as the symbolic or perceived value of each of these residential areas keeps these gaps in prices entrenched. As for land prices, the densification of buildings explains to some extent the widening gaps in prices between some sectors of the city, but this one factor is not enough to explain the extent of the observed evolutions
