La protection de l’enfant constitue une préoccupation majeure de notre droit, afin que le mineur ne soit pas victime d’un dommage. Cette protection est en premier lieu assurée par la famille. Il peut donc paraître surprenant que l’enfant soit victime de sa famille, ce d’autant plus que les parents doivent agir dans l’intérêt de l’enfant. La notion d’enfant victime de sa famille n’existe pas en tant que tel dans notre droit. La victime supporte souvent un dommage causé par un tiers et non par un membre de sa propre famille. L’étude des situations où l’enfant pourrait subir une atteinte à ses droits de la personnalité, en raison d’une action ou d’une omission de l’un des membres de sa famille, a toutefois permis la conceptualisation de la notion d’enfant victime de sa famille. Il a ainsi été possible de qualifier les différentes réalités rencontrées, en fonction de leurs ressemblances ou de leurs dissemblances. Cette analyse empirique a conduit à déterminer des catégories d’enfants victimes de leurs familles auxquelles correspondent un régime de protection. Elle a notamment eu pour conséquence la recherche de nouveaux instruments de protection adaptés aux spécificités des hypothèses étudiées. Ce processus de catégorisation a permis l’accès à la juridicité des réalités sociales et familiales appréhendées. Il a également été l’occasion de mettre en évidence les fondements de la notion d’enfant victime, dans le sens où le droit a consacré des situations classiques d’enfants victimes de leurs familles. L’apparition de nouvelles réalités sociales a cependant rendu nécessaire le renouvellement de la notion d’enfant victime de sa famille, afin de pallier les limites des fondements de la notion et de garantir la représentation effective de ce phénomène dans le discours juridique. / The child protection represents a major cause for concern of our law, so that the minor doesn’t sustain damage. This protection is firstly performed by the family. So, it may seem surprising that the child is victim of his family, as far as parents must act in the interests of the child. The notion of child victim of his family doesn’t exist as such in our law. The victim often endures an injury caused by a third person and not by a family member. The study of situations where the child may suffer an infringement of his personality rights, due to act or omission of one of the family members, allowed conceptualization of the notion of child victim of family. It was thus possible to characterize the different realities encountered, according to their similarities or dissimilarities. This empirical analysis led to ascertain categories of child victims of their families and the corresponding legal system. It had especially as a consequence new protection instruments research, appropriate to specifics assumptions studied. This process allowed social or family realities encountered getting to legal validity. It was also an opportunity to bring out foundations of the concept of child victim of family, in so far as law has hallowed situations of child victims of their families. However, emergence of new social realities necessitated the renewal of the concept of child victim of family, in order to alleviate the limits of the foundations of the notion and to guarantee effective representation of this phenomenon in legal speech.

La maladie d’Alzheimer (AD) est la principale cause de démence neurodégénérative, caractérisée à 95% par des formes tardives (LOAD) qui présentent des troubles mnésiques et progressent lentement. Cependant, environ 5% des patients atteints d’AD présentent une forme précoce de la maladie (EOAD) débutant avant 65 ans. Bien que le substratum lésionnel soit identique à la LOAD, l’EOAD est caractérisée par une plus grande sévérité des dépôts de plaques amyloïdes, des enchevêtrements neurofibrillaires et de l’atrophie cérébrale. De plus, l’EOAD est plus hétérogène que la LOAD, car même si la majorité des troubles sont mnésiques il existe une proportion importante de formes atypiques affectées par des troubles du langage, visuospatiaux ou exécutifs. Bien que de nombreuses études en imagerie TEP 18F-FDG aient permis de caractériser métaboliquement l’EOAD par rapport à la LOAD ou à un groupe de contrôles sains, très peu différentiaient pas les formes typiques (mnésiques) des formes atypiques. Dans ce travail de thèse, nous avons examiné les données d’imagerie TEP 18F-FDG, complémentées par l’IRM structurelle, afin d’améliorer la caractérisation et la compréhension des formes typiques et atypiques d’EOAD. Suite à un premier travail d’harmonisation des reconstructions TEP 18F-FDG entre deux machines GE et Siemens ayant toutes deux servies à l’acquisition des données patients, notre second objectif a été d’étudier à l’inclusion sur le cerveau entier les patterns hypométaboliques caractéristiques des différentes formes d’EOAD et leurs corrélations potentielles avec la performance neuropsychologique. Cette étude a montré que chaque forme clinique d’EOAD était caractérisée par des patterns hypométaboliques spécifiques fortement corrélés aux symptômes cliniques et aux scores neuropsychologiques du domaine cognitif associé. Par la suite, nous nous sommes intéressés à la progression sur 3 ans de l’hypométabolisme sur la surface corticale en fonction des formes typiques ou atypiques d’EOAD. Bien que des patterns similaires d’évolution de l’hypométabolisme entre les formes typiques et atypiques aient été observés au niveau du cortex pariétal, seules les formes atypiques ont présenté une réduction du métabolisme bilatérale plus importante au niveau du cortex orbito-frontal latéral associée à des déclins cognitifs plus sévères. Temporellement, les résultats suggèrent que l’hypométabolisme chez les formes typiques progresserait selon un axe antérieur-vers-postérieur en cohérence avec les stades de Braak et Braak, alors que l’hypométabolisme chez les formes atypiques progresserait selon un axe postérieur-vers-antérieur. Pris ensemble, ces résultats confortent l’hypothèse d’une distribution différente de la pathologie tau en termes de charge et d’évolution temporelle entre ces deux formes d’EOAD. Notre dernier objectif a été de déterminer les capacités discriminatives des données TEP 18F-FDG, seules ou combinées aux données de l’IRM structurelle, afin de classifier de manière automatique et supervisée des patients atteints d’EOAD en forme typique ou atypique. Nous avons mis en application des algorithmes de machine learning combinés à des méthodes de validation croisée afin d’évaluer les influences de diverses composantes sur les performances de classification. Des précisions équilibrées maximales égales à 80,8% en imagerie monomodale TEP 18F-FDG et 92,4% en imagerie multimodale TEP 18F-FDG/IRM T1 ont été obtenues, validant ainsi la TEP 18F-FDG comme un biomarqueur sensible de l’EOAD et soulignant l’apport incontestable de la multimodalité. En conclusion, nos travaux ont permis une meilleure caractérisation et compréhension des formes cliniques d’EOAD, ouvrant la voie à un management personnalisé du patient et des traitements plus efficaces pour ces formes distinctes. / Alzheimer’s disease (AD) is the most common form of neurodegenerative dementia, characterized at 95% by late-onset forms (LOAD) which present episodic memory impairments and progress slowly. However, 5% of AD patients have an early-onset form (EOAD) of the disease whose onset begins before 65. Although the lesion substratum is similar between EOAD and LOAD, EOAD has more severe neuritic plaque deposits, neurofibrillary tangles and brain atrophy. Moreover, EOAD is more heterogeneous than LOAD, because even if most of the impairments are about episodic memory there is a high proportion of atypical forms impaired in language, visuospatial or executive functions. Although many 18F-FDG PET studies allowed to metabolically characterize EOAD compared to LOAD or healthy controls group, very few differentiated typical from atypical forms. In this thesis, we examined 18F-FDG PET data, complemented by structural MRI, in order to improve characterization and comprehension of typical and atypical forms of EOAD. Following a first harmonization work between 18F-FDG PET reconstructions from both GE and Siemens scanners used for the acquisition of patient data, our second aim was to study at baseline on the whole brain hypometabolic patterns characterizing the clinical forms of EOAD and their correlations with neuropsychological performance. This work showed that each clinical form of EOAD was characterized by specific hypometabolic patterns highly correlated with clinical symptoms and neuropsychological performance of the associated cognitive domain. Then, we focused on the 3-year hypometabolism progression on the cortical surface according typical or atypical forms of EOAD. Although similar patterns of hypometabolism evolution between typical and atypical forms were observed in parietal cortices, atypical only showed a more severe reduction of metabolism in lateral orbitofrontal cortices associated with more severe cognitive declines. Temporally, the results suggest that hypometabolism in typical forms would progress according to an anterior-to-posterior axis coherently with Braak and Braak stages, whereas in atypical forms hypometabolism would progress according a posterior-to-anterior axis. Taken together, results consolidate the hypothesis of a different tau distribution in terms of burden and temporal evolution between both forms of EOAD. Our last goal was to determine the discriminative power of 18F-FDG PET data, alone or combined to structural MRI data, in order to automatically classify in a supervised manner EOAD patients into typical or atypical form. We applied machine learning algorithms combined to cross-validation methods to assess influence of some components on classification performances. Maximum balanced accuracies equal to 80.8% in monomodal 18F-FDG PET and 92.4% in multimodal 18F-FDG PET/T1 MRI were obtained, validating 18F-FDG PET as a sensible biomarker of EOAD and highlighting the incontestable contribution of multimodality. In conclusion, our works allowed a better characterization and comprehension of clinical forms of EOAD, paving the way to personalized patient management and more effective treatments for these distinct clinical forms.

For a long time, I have been thinking about the practice of sexuality concepts among nursing students since they have to give instructions of the related issues as familial planning and STD/AIDS prevention; sometimes they are victims of their own setting. This transversal, exploratory, descriptive, quantitative study aimed at investigating among nursing students their knowledge, practice and sources of information on contraceptive methods and STD/AIDS. Moreover, it approaches some aspects of sexual-life practice as well as its consequence. A semi-structured questionnaire was used for collecting data. The results showed that the majority of the students had some information on this issue when attending high school period, especially on contraceptive methods as the use of condoms, pills and withdrawal method. AIDS was the most stressed subject among STD. Learning this subject was more effective when they attended graduation period, especially in the 4th grade during the class of Nursing in the Care of Transmitted Diseases. The sources that most contributed for their knowledge were the classes and related reading. They have had little information from their parents on this issue. They reported the initial age of 10 to 13 years recommended to start receiving information on contraceptive methods and STD/AIDS prevention. Condoms and pills are the most effective contraceptive methods according to them. The great majority of them showed a misunderstanding in relation to some contraceptive methods such as condoms and pills playing a role in the prevention of STD. Seventh seven percent of them have just started their sexual life; out of these, 45.7% in the age of 16 to 18 years. The majority of the students stated to know how to prevent STD, however some of them did not make use of this knowledge. The most used contraceptive methods were the combination of pills and condoms, and/or the single use of one of them. Some of them, who made use of pills and other contraceptive methods, without being the condoms, did not care about the risk of STD/AIDS contamination. Behavioral aspect was the greatest constraint between reason/emotion in relation to STD/AIDS prevention and unwanted pregnancy . The approach of this study is to provide better understanding on subjects related to human sexuality for the nursing students, therefore they will be able to work on these themes at hospitals, HBU (Health Basic Units) or at elementary or high schools. Without this learning either their professional activities or their own behavior in relation to sexual issues will be impaired. / A formação dos profissionais da saúde abrange diversos aspectos tais como o seu papel social e assistencial; de pesquisa e de educação, ou seja, são preparados para atender as pessoas em todas as suas necessidades. Há muito, venho refletindo sobre a interiorização dos conceitos sobre a sexualidade entre os acadêmicos de enfermagem, visto que, apesar de transmitirem conhecimentos à clientela sobre temas relativos a planejamento familiar e prevenção de DST/HIV/AIDS, algumas vezes têm sido as vítimas neste contexto.O presente estudo é do tipo transversal, exploratório descritivo com abordagem quantitativa, com o objetivo de investigar o conhecimento, uso e as fontes de informações dos métodos contraceptivos e prevenção de DST/AIDS, além de abranger o estudo de aspectos da vivência sexual e sua conseqüência. Para tanto foi utilizado um questionário semi-estruturado entregue as acadêmicas da 1ª a 4ª série do Curso de Graduação em Enfermagem da Faculdade de Medicina de São José do Rio Preto. Os resultados mostraram que a maioria das acadêmicas referiu ter recebido informações no ensino médio sobre métodos contraceptivos, principalmente sobre preservativos, pílula anticoncepcional e coito interrompido. A AIDS aparece como a DST mais abordada, o aumento do conhecimento ocorreu no decorrer da graduação, firmando-se efetivamente na 4ª série na disciplina de Enfermagem em Doenças Transmissíveis. As acadêmicas referiram como fontes que mais contribuíram as aulas e leituras específicas. A participação dos pais nesta educação foi incipiente. Acreditam que a idade ideal para se iniciar as orientações sobre métodos contraceptivos e DST/HIV/ADS está entre 10 e 13 anos. Citam como métodos contraceptivos mais seguros os preservativos e os anticoncepcionais orais. Há uma distorção e compreensão errônea por parte de muitas acadêmicas, que alguns métodos contraceptivos como os anticoncepcionais orais e injetáveis e o DIU contribuam em muito para a prevenção de DST. Setenta e sete porcento das acadêmicas já iniciaram a vida sexual, destas 45,7% na idade entre 16 e 18 anos. A maioria (97,8%) afirma saber como prevenir DST, porém nem todas fazem uso do conhecimento adquirido. Os métodos contraceptivos mais utilizados são a combinação de anticoncepcionais orais e preservativos, e/ou pelo uso único de um dos dois, sendo que, as que fazem uso somente da pílula e outros métodos que não a utilização do preservativo, se expõem ao risco de contrair DST/HIV/AIDS. A questão comportamental ainda é a maior barreira entre a razão/emoção dificultando a prevenção das DST/AIDS e gravidez não planejada. A abordagem desta pesquisa reside na perspectiva de inserção de estudantes de enfermagem como orientadores de temas relacionados à sexualidade humana, seja em hospitais, ambulatórios, UBS ou escolas do ciclo fundamental e médio. Entende-se que sem este preparo, tanto sua vivência profissional quanto seu comportamento serão prejudicados em relação à questão sexual e a reflexão sobre sua própria sexualidade.

En el gen de la proteïna priònica, o PRNP, hem observat que el particular patró de variació que hem trobat basant-nos en dades de seqüenciació en humans es deu a selecció positiva, i que el mètode utilitzat per detectar selecció és crític. Utilitzant dades basades en SNPs es pot introduir un biaix al aplicar tests de neutralitat basats en diversitat de seqüències, i això pot portar a conclusions errònies. A més, hem vist que els polimorfismes en els codons 129 i 219 presenten gran diferències de freqüència en diferents poblacions humanes i també hem vist que aquestes posicions estan fixades en ximpanzés. La variació trobada en controls ha estat comparada amb el patró de variació existent en pacients per la mateixa regió. La reseqüenciació del gen PRNP en un gran nombre de mostres humanes i de ximpanzés ens ha permès obtenir un gran nombre d´informació d´aquest gen. / In the prion gene or PRNP, we have observed that the particular pattern of variation that we have found in this gene based on sequencing data in humans is due to positive selection, and that the method and the approach used to detect this selection critical. Ascertainment bias can be introduced by using SNP data and applying neutrality tests based on sequence diversity, therefore leading to anomalous conclusions being drawn. Moreover, we have seen that polymorphisms in codon 129 and 219 have big differences in frequency in different human populations and we have also seen that these positions are fixed in chimpanzees. The normal variation that we found in controls have been then compared with patients for the same region. The resequencing of PRNP in a very large sample of humans and chimpanzees has provided a great deal of information on this gene.

Objectif. Décrire les attitudes et habitudes de Canadiens relativement à la préparation des aliments à la maison et au repas familial, afin de saisir les motivations à exploiter lors de la promotion de ces habitudes. Méthodes. Un sondage électronique de 39 questions à choix multiples a été placé sur le site des Diététistes du Canada du 16 novembre au 22 décembre 2006. Les énoncés analysés abordent la perception des bénéfices associés à la cuisine maison, à la planification des soupers et au repas familial, les obstacles à cuisiner, le temps de préparation et la planification des soupers, l’apprentissage de la cuisine, les sources d’idées recettes et la consommation des repas familiaux. Résultats. Au total, 4080 individus ont complété le questionnaire. Bien qu’ils croient que la cuisine maison puisse améliorer la qualité de l’alimentation et les comportements alimentaires, les répondants rencontrent plusieurs obstacles à la préparation des aliments au quotidien, parmi lesquels le manque de temps, d’énergie, d’idées et de planification. Bien qu’une majorité de Canadiens soupent en famille, il existe des écarts selon les groupes d’âge et les régions canadiennes. Conclusion. Cette étude souligne la pertinence d’élaborer des stratégies de communication pour informer les consommateurs sur les bénéfices de la cuisine maison et du repas en famille, afin de les aider à surmonter les défis associés à ces habitudes. Si les nutritionnistes sont des intervenants de choix, des collaborations interdisciplinaires sont proposées pour promouvoir une cuisine maison saine, bien planifiée, simplifiée et savourée en famille. / Objective. To describe Canadians' attitudes and habits with regard to home food preparation for family meals in order to seize the motivations to be exploited during the promotion of these habits. Methods. An electronic poll of 39 multiple-choice questions was posted on the Dieticians of Canada's website from November 16th till December 22nd, 2006. The analyzed statements cover the perception of the benefits associated with home cooking, supper planning and family meals, the barriers to cooking, the preparation time and supper planning, the development of cooking skills, sources of recipes ideas and consumption of family meals. Results. A total of 4080 individuals completed the questionnaire. Although they believe that home cooking can improve the food quality and eating habits, the participants meet several barriers to food preparation in everyday life, among which the lack of time, energy, ideas and planning. Although a majority of Canadians have family suppers, there are gaps according to age groups and Canadian regions. Conclusion. This study highlights the relevance of elaborating communications strategies to inform consumers of the benefits of home cooking and family meals in order to help them to deal with the challenges associated with these habits. If nutritionists are the best interveners, interdisciplinary collaborations are proposed to promote a healthy, well planned home cooking enjoyed with the family.

Cette thèse propose une analyse des transformations postcommunistes en Roumanie à partir d’une étude de la structuration de trajectoires familiales. La réflexion sur les itinéraires très variés de ces trajectoires familiales met en valeur les pratiques développées par les familles dans la construction de leur mode de vie quotidienne après la chute du communisme. L’approche utilisée privilégie deux axes d’analyse. Le premier vise les aspects socio-structurels concernant les cadres de la vie incluant les aspects matériels, alors que le deuxième, l’axe socio-symbolique, concerne les aspects subjectifs liés au vécu des acteurs en corrélation avec le contexte social en mutation. L’analyse est fondée sur des éléments issus de la théorie de la structuration qui ont contribué à la construction du cadre conceptuel. Elle s’appuie aussi sur la méthodologie qualitative qui comprend des récits de vie obtenus à partir des entretiens semi-dirigés réalisés avec les membres de 11 familles. Les thématiques retenues après l’analyse du corpus de données nous ont permis d’identifier des stratégies que les familles ont mises en place et les projets familiaux qui ont orienté leur parcours de vie durant la période de transition postcommuniste. Ces deux concepts révèlent des éléments liés à l’ordre général permettant ainsi la mise en évidence des tendances structurelles de la société postcommuniste. / This thesis presents an analysis of the process of post-communist transformation in Romania, through a study of the structure of family trajectories. An examination of the wide variety of family trajectories highlights the practices developed by families in rebuilding their way of life after the fall of communism. The approach adopts two axes of analysis. The first is the socio-structural framework for life including material aspects, while the second axis, the socio-symbolic axis addresses subjective aspects related to the experiences of actors within their changing social context. The analysis draws on the theory of structuration in its conceptual framework. It is also based on qualitative methodology which includes life stories obtained from semi-structured interviews conducted with members of 11 families. The themes selected after analysis of the data corpus allows us to identify strategies that families have put in place and family plans that have shaped their life course during the post-communist transition. These two concepts reveal elements related to the general order allowing the identification of structural trends of post-communist society in Romania.

La thèse s'intéresse à l'accompagnement familial des apprentissages scolaires en mathématiques, mais aussi et surtout à l'organisation non discriminante de ses conditions. La " culture didactique " partagée dans notre société s'adapte de moins en moins aux régulations de la scolarité obligatoire. En effet, en se focalisant sur le repérage des difficultés individuelles et en encourageant les interventions précoces à l'extérieur de l'institution d'enseignement, elle transforme les aléas " ordinaires " de l'apprentissage en dysfonctionnements. Certaines tentatives d'amélioration insistent sur l'information et la communication entre école et parents. Or les discours éloignent souvent de la réalité des actions. Les " exercices à faire à la maison ", en transmettant des comportements, jouent un rôle complémentaire important. Certes, ils font rapidement surgir les divergences, parce qu'ils rendent visibles les contre-performances des élèves, et suggèrent toutes sortes de rectifications. Les devoirs sont par conséquent souvent accusés d'introduire des disparités et de pertuber les relations entre protagonistes. La thèse réexamine ce point de vue, en étudiant d'autres formes d'étude, qui s'ajusteraient mieux aux besoins des institutions didactiques. Pour simplifier la circulation des savoirs mathématiques les plus fréquemment utilisés, la société a mis en place des instruments culturels. Mais certains ont été détournés de leur fonction, ce qui a rompu des équilibres didactiques essentiels. La récitation des tables de multiplication fournit un exemple paradigmatique de la dénégation des transpositions. Les régressions métadidactiques ont en effet lentement modifié une ancienne répartition des tâches entre institutions, jusqu'à dédidactifier tout un pan de l'enseignement du calcul. La thèse éclaire la compréhension de ces phénomènes à l'aide de la Théorie des Situations Didactiques. Elle propose un nouveau concept pour une ingénierie spécifique de l'entraînement et de la familiarisation des élèves avec les connaisances les plus fondamentales : les assortiments didactiques.

They are protection nets based on the empiric observation of the social organization of the “familiar net” and in the complexity of the relations in the context of the hard conditions of life and habitation. In this case, it is also considered the inefficacy of the state to provide habitation and security. These factors are associated to the difficult conditions of work market. This way the families create survival strategies. The home fight is the daily work involving, home tasks, cleaning, the food preparation, children cares. The word fight means also demands and reflections.‟ It translates the poor conditions. It represents the vision of the family and society that involve the conceptions of the domestic work and a real situation of responsibility and the purpose, especially women and their families. In the observation research in which the researcher takes part, I realized a case history. I observed four familiar nets. I realized an operationalism of the protection and economy as the condition of the survival possibility in the context of the extreme poverty. My analysis is based in the hypothesis of the solidarity in the” rural world”. The comprehension is based on the symbol of the old person in order to understand the family, before the migration to capital in the rural universe or in the interior cities of the state. My study is based on the action theory of Bourdieu (1996 to 2000) and the conception of poor family. (Sarti, 2005). The thesis concluded that family produce a protection strategy of survival in the where the family economy is estimated, not only in numbers but the estimation is based on living experiences. / Objetivo analisar o modo como as famílias moradoras de bairros pobres urbanos, especificamente, o bairro Pirambu no período de 2006 a 2009, constroem arranjos econômicos e redes de proteção, com base na constatação empírica da organização da “família em rede” e da complexidade dessas relações num contexto de parcas condições de vida e moradia; considerando também a ineficiência do Estado em prover habitação e seguridade, que, associadas à precariedade do mercado de trabalho, levam a família a criar estratégias de sobrevivência. A “luta da casa” é o trabalho cotidiano envolvendo os afazeres do lar, como a limpeza, o preparo dos alimentos e o cuidado dispensado às crianças. O termo “luta” também é sinônimo de ‘denúncias ou reflexões’, enfrentamento e traduz a condição de ser pobre, sendo assim representativo de uma visão de família e sociedade que transpõe concepções de trabalho doméstico e desvenda a real situação de responsabilidade e compromisso, principalmente das mulheres para com suas famílias. Na pesquisa de “observação direta”, realizei um “estudo de caso” com quatro redes de parentesco, analisando a operacionalização da proteção e da economia como condições de possibilidade para sobrevivência num contexto de extrema pobreza. Para esta análise, elenco a hipótese da influência de solidariedade do “mundo rural” apreendida [pelos idosos, pessoa de referência para análise na família] antes da migração para Capital, no universo rural ou em cidades do interior do Estado e elejo os conceitos da Teoria da Ação de Bourdieu (1996, 2000), e as concepções de família pobre de Sarti (2005). A tese chegou a conclusão de que a família produz um mecanismo de proteção numa rede de apoios, onde a economia familiar não se mede só em números, mas é expressa em vivências. / Le but est d’analiser la façon comme les familles habitantes dans des quartiers pauvres urbains, particulièrement, dans le quartier Pirambu, dans la période de 2006 à 2009, construisent des moyens économiques et des réseaux de protection, basé sur la constatation empirique de l’organisation de la « famille en réseau » et de la complexité de ces relations dans un contexte de conditions limitées de vie et de logement ; en considérant aussi l’inefficacité de l’État d’approvisionner habitation et sécurité, qui associées au manque du marché de travail, mènent la famille a créer des stratégies de survivance. La « lutte de la maison » est le travail quotidien qui englobent les tâches ménagères, comme le ménage, la préparation des nourritures et l’attention dispensés aux enfants. Le terme « lutte » est aussi synonyme de ‘dénonciation ou réflexions’, affrontement et traduit la condition d’être pauvre, donc représentatif d’une vision de famille et société qui dépasse des conceptions de travaux domestiques et montre la réelle situation de responsabilité et engagement, surtout des femmes avec leurs familles. Dans la recherche « d’observation direct », j’ai réalisé une « étude de cas »avec quatre réseaux de proches parents, en analisant l’operationalisation de la protection et de l’économie comme des conditions de possibilités pour la survie dans un contexte d’extrême pauvreté. Pour cette analyse, je liste l’hypothèse de l’influence de solidarité du « monde rural » saisie [par les âgés, personne de référence pour l’analyse dans la famille] avant la migration pour la Capitale, dans l’univers rural ou dans les villages à la campagne et j’élis les concepts de la Théorie de l’Action de Bourdieu ( 1996, 2000 ), et le conceptions de famille pauvre de Sarti (2005). La thèse conclut que la famille produit un mécanisme de protection dans un réseau de supports, où l’économie familiale ne se mésure pas qu’en chiffres, pourtant c’est exprimée sur des expériences.
