Considérant le contexte brésilien de la première décennie du XXI siècle, d’intense mobilité sociale, on cherche vérifier dans quelles mesures tels mouvements de mobilité se sont fait présents entre les jeunes agriculteurs familiaux, en délimitant comme champ empirique pour cet étude la commune de São Lourenço do Sul – RS. Ainsi, on étabilit comme objectif principal de cette thèse l’analyse les dynamiques de mobilité sociale entre les jeunes agriculteurs familiaux, à partir du plan des individus, en consideránt leurs families comme unités analytiques. On cherche, donc, dans les parcours intergénérationales parcourus par les families de ces jeunes, soit vérifier les mouvements des mobilités social qui ont eu lieu, soit comprendre les éléments qui ont contribué à sa concrétisation. Pour repérer la construction de cette thèse on se sert du référentiel théorique proposé par Archer (1998), a partir duquel la réalité sociale es conçue selon trois temporalités différents, interdépendantes entre soi, mais qui permettent l’analyse indépendante de chacune d’elles, en définissant comme contexte d’immersion sociale des jeunes – antérieur à l’action – aussi bien les mouvements de mobilité social qui ont eu lieu dans le pays pendant la première décennie du XXI siècle, au plan macro, que se parcours intergénérationnels, au plan micro ; en ce qui concerne la portée des interactions – simultanées à l’action – des différents types et formats de relations sociales établis par les acteurs ont été analysés, à l’intérieur et à l’exterieur des ses unités de production. Finalment, pour aborder la troisième temporalité, de l’élaboration des structures – en ce qui concerne le futur -, on s’est adressé aux projets des jeunes comme des anticipations présents d’un avenir désiré, bornés par l’interméde de la réflexivité. A fin de réaliser cette analyse les jeunes ont été séparés on trois groupes distincts, en observant que le point de repère principal pour la mobilité ascendante entre les jeunes de families plus aisées a été l’acquisition de propriétés ; entre les jeunes des familles moins aisées le principal aspect a été la croinssance des garçons ; puisqu’ils ajoutent la main d’oeuvre à la famile ; finalement, entre les jeunes de familles marginalisées on n’a pas remarqué des dynamiques significatives de mobilité, car les générations actuelles possèdent des conditions aussi précaries que les anteriéures. A la fin, on observe que, d’une façon géneral, les dynamiques de mobilité sociale ascendante que ont caractérisé le pays au cours de la première décennie du XXI siècle ont été également remarqués entre les familes des jeunes agriculteurs familiaux interviewés. / Considerando-se o contexto brasileiro da primeira década do século XXI, de intensa mobilidade social, busca-se verificar em que medida tais dinâmicas de mobilidade se fizeram presentes entre os jovens agricultores familiares, definindo-se como campo empírico para o estudo o município de São Lourenço do Sul – RS. Assim sendo, estabelece-se como objetivo principal da tese a análise das dinâmicas de mobilidade social entre os jovens agricultores familiares, a partir do plano dos indivíduos, tomandose as famílias dos jovens como unidade analítica. Busca-se, então, nas trajetórias intergeracionais percorridas pelas famílias dos jovens tanto verificar as dinâmicas de mobilidade social ocorridas quanto compreender os elementos que contribuíram com sua concretização. Para balizar a construção desta tese utiliza-se o referencial teórico proposto por Archer (1998), a partir do qual a realidade social é concebida a partir de três diferentes temporalidades, interdependentes entre si, mas que permitem a análise independente de cada uma delas, definindo-se como contexto de imersão social dos jovens – anterior à ação - tanto as dinâmicas de mobilidade social ocorridas no país durante a primeira década do século XXI, num plano macro, quanto suas trajetórias intergeracionais, em plano micro; já no âmbito das interações – simultâneas à ação – foram analisados os diferentes tipos e formatos de relações sociais estabelecidas pelos atores, no interior e exterior de suas unidades de produção. Finalmente, para tratar da terceira temporalidade, da elaboração das estruturas - referente ao futuro -, abordaramse os projetos dos jovens como antecipações presentes de um futuro desejado, mediados pela reflexividade. Para realizar a análise os jovens foram separados em três grupos distintos, observando-se que o marco principal para a mobilidade social ascendente entre os jovens de famílias mais capitalizadas foi a aquisição de propriedades; entre os jovens de famílias descapitalizadas o aspecto principal foi o crescimento dos filhos homens, que agregaram mais mão de obra à família; finalmente, entre os jovens de famílias marginalizadas, não se observaram dinâmicas significativas de mobilidade, pois as gerações atuais possuem condições tão precárias quanto as anteriores. Ao final, observa-se que, de um modo geral, as dinâmicas de mobilidade social ascendente que caracterizaram o país ao longo da primeira década do século XXI também foram observadas entre as famílias dos jovens agricultores familiares entrevistados. / Considering the Brazilian context of the first decade of this century, the intense social mobility, it seeks to ascertain to what extent such mobility dynamic were present among the young farmers, defining itself as the empirical field of the study the municipality of São Lourenço do Sul - RS. Therefore, establishing itself as the main objective of the thesis analyse the dynamics of social mobility among young farmers, from the plane of the individuals, taking the families of young people as analytical unit. Search, so, is the intergenerational trajectories traversed by families of young people both verify the dynamics of social mobility occurred as understanding the elements that contributed to its realization. To mark the construction of this thesis uses the theoretical framework proposed by Archer (1998), from which social reality is conceived from three different temporalities, interdependent, but which allow independent analysis of each of them, it defining itself as context for social embeddedness of youth - before the action - both the dynamics of social mobility occurred in the country during the first decade of this century, a macro level, as their intergenerational trajectories in micro level, already in the context of interactions - simultaneous action – was analyzed the different types and formats of social relations established by the actors, inside and outside of their production units. Finally, to treat the third temporality, of the elaboration of structures – relative to future – was approached projects of young people as gifts anticipations of a desired future, mediated by reflexivity. To perform the analysis, the young were separated into three groups, noting that the main landmark for upward social mobility among young of the capitalized families was the property acquisition; among young families without capital the main aspect was the growth sons, which added more manpower to the family, and finally among young of the marginalized families, there were no significant dynamic of the mobility, because the current generations have poor condition such as the previous ones. Finally, we observe that, in general, the dynamics of upward mobility that characterized the country during the first decade of this century were also observed among families of young farmers interviewed.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Esta tese é composta por três artigos que permitiram avaliar o efeito da exposição ao tabagismo durante a gestação e no início da infância sobre o crescimento linear e ganho de peso do nascimento à adolescência, além de verificar o efeito do nível socioeconômico no início da infância e da mobilidade social sobre a adiposidade até a adolescência. Foram utilizados para este fim os dados de uma coorte de crianças nascidas entre 1994 e 1999 na cidade de Cuiabá-MT. Essas crianças fizeram parte de um estudo de base populacional realizado na cidade de Cuiabá, entre 1999 e 2000, com 2405 crianças (0 a 5 anos) e foram selecionadas aleatoriamente em unidades básicas de saúde quando da vacinação. As mães foram entrevistadas após a vacinação, quando foram obtidos dados relativos à exposição ao tabagismo gestacional, tabagismo passivo, nível socioeconômico das famílias e dados antropométricos. Entre 2009 e 2011, após aproximadamente 11 anos, essas crianças foram localizadas por meio do Censo Escolar e então 1716 adolescentes entre 10 e 17 anos de idade (71,4% da população) foram reavaliados nas escolas da rede pública e privada de Cuiabá, de 18 municípios do estado e outras 5 capitais do país. A análise por modelos lineares de efeitos mistos permitiu verificar a mudança de estatura e Índice de Massa Corporal (IMC) entre o nascimento e a adolescência. O primeiro e o segundo artigo desta tese avaliaram o efeito da exposição ao tabagismo materno durante a gestação e no início da infância sobre o crescimento linear e o IMC entre o nascimento e a adolescência. Crianças expostas ao tabagismo materno durante a gestação e no início da infância apresentaram menor estatura desde o nascimento até a adolescência quando comparadas às crianças não expostas. Quanto à adiposidade, entre o nascimento e a infância a mudança do IMC foi similar entre as crianças expostas e não expostas ao tabagismo materno, porém, entre a infância e a adolescência, aquelas expostas apenas durante a gestação mostraram maior ganho de IMC. Em conjunto, os dados corroboram o efeito deletério do tabagismo sobre o crescimento, efeito já bastante estudado, mas também indicam que avaliar e comparar exposição gestacional com pós-gestacional é importante, dado que seus efeitos parecem ser diferentes. O terceiro artigo avaliou o efeito do nível socioeconômico no início da infância e da mobilidade social entre a infância e a adolescência sobre o IMC do nascimento à adolescência. Para avaliar o nível socioeconômico, as famílias foram classificadas em nível econômico alto, médio e baixo, a partir do Critério de Classificação Econômica Brasil. Foi observada expressiva mobilidade social na população, principalmente entre os de menor nível econômico. Houve maior aumento do IMC entre o nascimento e a adolescência entre aqueles de maior nível econômico na infância e aqueles que permaneceram nas classes mais elevadas, indicando que a posição inicial foi o maior determinante das mudanças observadas no IMC. / This thesis consists of three papers that allowed us to evaluate the effect of exposure to smoking during pregnancy and early childhood on linear growth and weight gain from birth to adolescence, and to verify the effect of socioeconomic position in early childhood and social mobility on adiposity until adolescence. For this purpose, we used the data of a cohort of children born between 1994 and 1999 in the city of Cuiabá. They were part of a population-based study conducted with 2,405 children (05 years) who attended one of the ten basic health units selected for vaccination in the city of Cuiabá between 1999 and 2000. Between 2009 and 2011, after approximately 11 years, these children were located through the School Census; thus, 1,716 adolescents aged 10 to 17 years old (71.4% of the population) were reassessed in the public and private schools of Cuiabá, of 18 counties in the state and five other capitals in the country. The mothers were interviewed after vaccination to obtain data regarding their exposure to smoking during pregnancy, passive smoking, socioeconomic status, and anthropometric information. The linear mixed-effects analysis showed the change in height and body mass index (BMI) from birth to adolescence. The first and second articles in this thesis evaluate the effect of exposure to maternal smoking during pregnancy and early childhood on linear growth and BMI from birth to adolescence. Children exposed to maternal smoking during pregnancy and early childhood were shorter from birth to adolescence than the children not exposed. As for adiposity between birth and childhood, the BMI change was similar between children exposed and not exposed to maternal smoking; however, between childhood and adolescence, those exposed only during gestation showed greater gains in BMI. Together, these data not only confirm the deleterious effect of smoking on growth, which has been extensively studied, but also indicate that it is important to evaluate and compare gestational to post-pregnancy exposure because their effects seem to be different. The third paper examines the effect of socioeconomic status in early childhood and social mobility from childhood to adolescence on BMI from birth to adolescence. To assess socioeconomic position, the families were classified into high, medium, and low economic levels based on the Brazil Criterion of economic classification. We observed significant social mobility in the population, especially among the lower economic group. We observed a greater increase in BMI from birth to adolescence among those from higher socioeconomic position in childhood and those who remained in the higher classes, indicating that the starting position was the major determinant of the observed changes in BMI.

Cette thèse prend pour objet les parcours biographiques d'émigrés comoriens et togolais, en s'intéressant à la double dimension de ces mobilités internationales, entendues à la fois comme des processus de mobilité spatiale et comme des trajectoires de mobilité sociale. Pour étudier ces mobilités, l'enquête a été menée en France et dans les deux pays d'origine. Près de 200 récits de vie, complétés par des observations au sein des familles, ont pu être réalisés auprès de non-émigrés, d'émigrés, d'émigrés de retour et de leurs proches. La recherche questionne le franchissement des frontières internationales comme moyen de s'affranchir des frontières sociales nationales, c'est-à-dire les manières dont les émigrés s'approprient la mobilité internationale et peuvent converti leurs expériences migratoires en ressources leur permettant de s'engager dans un processus de mobilité sociale ascendante. Cette enquête souligne que les histoires migratoires nationales, les conditions politiques restrictives de la mobilité internationale et les dispositions familiales à la migration se combinent pour construire des parcours inégaux. La comparaison multidimensionnelle entre des émigrés originaires de deux pays, aux propriétés sociales diverses, met d'abord en lumière l'influence centrale des histoires familiales et du milieu social d'origine des émigrés dans l'explication des parcours individuels. L'enquête démontre par ailleurs que les mobilités internationales conduisent les émigrés à traverser plusieurs espaces sociaux et nationaux et à s'engager dans des trajectoires qui mêlent à la fois des expériences d'immobilité et de mobilité sociale. Au-delà de ces expériences individuelles contrastées, la thèse indique enfin que la migration participe tout autant à reproduire les inégalités qu'à brouiller les frontières sociales du pays d'origine. / This thesis explores the life course of Comorian and Togolese migrants by focusing on. the dual dimension of international mobility, understood both as a spatial mobility process and as a social mobility trajectory. In order to investigate this mobility, the study was both conducted in France and in the two countries of origin. Nearly 200 life stories of non-migrants. migrants, returning migrants and their close relations were collected and completed by observations within the families. The research questions the crossing of international borders as a mean to overcome national social boundaries, that is to say, the ways migrants appropriate international mobility and convert their experiences into resources allowing them to begin a process of upward social mobility. This study stresses that the national migration history, the restrictive political conditions of international mobility and the families' dispositions for migration ail combine to create unequal individual courses. The multidimensional comparison of migrants from both countries that show diverse social characteristics highlights the central influence of family history and migrants' social background in the explanation of their persona! trajectories. The study also demonstrates that international mobility pushes migrants to cross several national and social spaces and to engage in paths that combine both experiences of immobility and social mobility. Beyond these contrasting individual experiences, the thesis finally shows that the migration process is perpetuating inequalities as well as blurring the social boundaries in the countries of origin.

Ce mémoire analyse le phénomène de mobilité sociale chez les individus racisés en prenant comme fondement de la réflexion le concept de « transclasse » de la philosophe française Chantal Jaquet. Prenant comme point de départ les travaux de Jaquet, cette étude interrogera dans un premier temps les caractéristiques de cette figure du transclasse, les partis pris de la philosophe ainsi que les limites d’un tel concept. Les analyses de films qui ponctuent le second mouvement de cette étude viendra compléter les hypothèses et illustrer nos propos ; ces analyses – portant sur un corpus de films français exclusivement – permettront d’étudier la place du transclasse-racisé au cinéma et les façons dont il est représenté à l’écran par les cinéastes. Ces deux grands temps du mémoire prendront en considération les contextes historique, politique et social français de la fin de la colonisation française à nos jours. Enfin, cette réflexion autour du transclasse-racisé s’appuiera sur la création qui accompagne ces recherches, un film documentaire, Le seul de la classe, tourné tout au long de l’année et réalisé au Québec. Ce film a pour objet le parcours d’individus racisés, leur rapport à une identité multiple et leur place dans la mobilité sociale dans la société québécoise. / This dissertation analyzes the social mobility phenomenon within racialized group basing its reflection on the French philosopher Chantal Jaquet’s « cross-class » concept. Considering the philosopher’s studies as a starting point, this dissertation will first question the cross-class’s features, the philosopher’s bias in her studies as well as the limits of such a concept. The film analysis which are present in the second part of this study will complete the hypothesis and illustrate our statements; these analysis – which exclusively focus on a corpus of French movies – will enable to study the racialized cross-class’s place in the cinema and the ways filmmakers represent him on the screen. These two parts of the study will take into account the historical, political and social contexts from the end of the French colonization until nowadays. Finally, this reflection around the racialized cross-class character will be based on the creation which accompanies this study, a documentary Le seul de la classe which was shot during this year and directed in Québec. This movie tackles the issue of racialized individuals’s journey, their relation to a multiple identity and their own place in the social mobility in the Quebec society.

Studiens syfte var att undersöka hur tillägnandet av skriftspråk kan bidra till kulturellt kapital med fokus på vad den processen innebär för individen. Urvalet har varit målstyrt och vänt sig till personer som har förändrat sin egen situation och uppnått akademiska eller yrkesrelaterade framsteg. Studien visar att när tillägnandet av skriftspråk bidrar till kulturellt kapital och social rörlighet resulterar det i att individen upplever en förändring i sitt habitus. En process som kan utmana individens möjlighet till att utifrån ett socialt- och psykologiskt perspektiv uppleva tillhörighet i de nya medelklassammanhangen. Det påverkar även individens tidigare familj- och vänskapsrelationer. Studien visar därtill att tillägnandet av skriftspråk kan ha en terapeutisk funktion för ett barn som har ett socialt problem och befinner sig i en utsatt situation. Studien visar att ett kulturellt kapital utvecklas av individens exponering för litteratur, behov av att uttrycka sig och tillfredsställelse i att skriva. Att tillägna sig skriftspråket bidrar till en upplevelse av att vidhålla egenmakt och förmågan att medverka i och påverka samhället. / The purpose of the study was to investigate how the acquisition of written language can contribute to cultural capital with a focus on what that process means for the individual. The selection has been goal-oriented and aimed at people who have created change for themselves and achieved academic and/or professional progress. The study shows that when the acquisition of written language contributes to cultural capital and social mobility, it results in the individual experiencing a change in their habitus. A process that can challenge the individual's ability to experience belonging in the new middle-class contexts from a social and psychological perspective. It also affects the individual's previous relationships to family and friends. The study also shows that the acquisition of written language can have a therapeutic function for a child who has a social problem and is socially vulnerable. The study shows that cultural capital is developed by the individual's exposure to literature, need for expression and satisfaction in writing. Acquiring the written language contributes to an experience of maintaining autonomy and the ability to participate in and influence society.

This ethnographic study investigates the experiences of those learning tailoring and trading in Freetown, Sierra Leone via apprenticeships, other on-the-job training or Technical and Vocational Education and Training programs (TVET). I examine these forms of occupational training by investigating the practices underway, how knowledge transmission occurs, as well as why learners engage with and what they get out of these activities. I consider how the job learners utilise occupational training as a manner of increasing social, cultural and economic capital in Bourdieu's sense of those terms to navigate the urban labour market.     I find that the learners aspire fundamentally to social mobility and a sense of self-worth. To achieve this, they use four main tactics: flexibility, reframing, co-operation and diligence. However, I find all tactics are developed in response to greatly circumscribed opportunities to obtain a good and stable income, and increased social status, due to structural inequality. Local political neoliberal discourse on youth unemployment emphasising diligence, belies these inequities and the limited ways in which social mobility is within the individual’s control. Hence, I argue, a focus on training without addressing structural inequality is inadequate.     As the training usually does not lead to paid and reliable employment, I argue it serves more fundamentally as a form of moral education and a vehicle for personal and social development. I argue it helps develop certain personal moral traits and alleviate society's concern about immoral "idle youth". Further, that it helps develop what I term resilience capital; that is, the hard-working and stubborn disposition developed by reframing previous experiences of adversity, which may later assist the individual in acquiring other forms of capital.     Although not its main focus, this study also seeks to contribute to academic scholarship through developing our understanding of knowledge transmission. I find that the process of knowledge transmission is fundamentally social and shaped by hierarchy, subjective positions of power, the inculcation of moral and ethical values, and more dependent for success on various forms of capital than it might at first appear.

This thesis examined how the association between immigrants’ occupational origin and destination varies in 33 European countries, depending on the opportunities for social mobility in the origin country. For absolute occupational mobility, the result from an LPM regression showed that first-generation female immigrants had an increased probability of upward mobility when the origin country offered more opportunities for social mobility. In contrast, first-generation male immigrants showed an increased probability of immobility when the origin country offered more opportunities for social mobility. For relative occupational mobility, a multivariate OLS regression showed that first-generation male immigrants from countries with more opportunities for social mobility were more immobile compared to origin countries with fewer opportunities. Based on the World Economic Forum’s Global Social Mobility Index, a variable representing the opportunities for social mobility in the origin country was created. The study used four waves of the European Social Survey and the International Socio-Economic Index (ISEI) to measure the mobility patterns in absolute and relative rates over the scores of opportunities for social mobility in the origin country. Second-generation immigrants showed no significant results, and no gender differences could be established. The results were discussed in relation to first-generation immigrants’ Status Loss.

This study uses the competing Burton Clark's "Cooling Out Theory" and Daniel Bell's "Theory of the Postindustrial Economy" to examine the function that for-profit colleges and universities (FPCUs) play in American higher education and how it is different from non-profit traditional colleges and universities (TCUs). This was done through three sections of analysis. The first examined if students who enroll at these FPCUs are less academically prepared than those attending non-profit traditional colleges or universities. The second tested if academic preparedness is associated with postsecondary performance at FPCUs to the same degree it is at TCUs. The final section of analysis looked at FPCU graduates to see if they have different short-term job outcomes when compared to traditional college graduates. This research utilizes The Beginning Postsecondary Survey 2009- a restricted-use longitudinal data set produced by the National Center for Education Statistics that followed 16,700 first-time college enrollees from 2003 until 2009. This data set includes information on student demographics, academic performance, enrollment history, and job outcomes. The results of this study indicated that when compared to traditional college students, FPCU students are less likely to be academically prepared for college and are more frequently characterized by risk factors that previous research has shown makes it less likely they will complete their degree. This research also found that unlike TCUs, high school academic performance is not associated with post-secondary performance or likelihood of degree attainment at FPCUs. Finally, it was observed that FPCU graduates were less likely to have jobs related to their degree and earned less income than TCU graduates, but had about the same degree of job satisfaction.
