Thus, two experiments were performed with 19 and 14 participants, mostly university students from PUC-SP, from several courses. The experimental task, which was presented and performed using a computer software (Meta 3), was performed in group, three participants each time, featuring a generation. By the end of each generation the oldest participant was substituted by a new naive one. The experimental task consisted in inserting numbers in empty espaces on the computer s screen. The relation between the numbers inserted by the participants and the numbers presented by the computer generated points, the individual consequence; and the relation between the sum of the numbers inserted by a participant and the sum of the numbers inserted by the others genrated bonuses, the cultural consequence. By the end of the participation, each participant was given R$0,01 for each 10 points or bonuses produced, by way of cost assistance. The Experiment 1 began with the forced ordering of participant responding in force, and later, the ordering was withdrawn. The results points out that ocurred operant selection and selecton and selection of the interlocking behavioral contingêncies and aggregate outcome with the ordering of participants responding and maintenance of it, and that when the ordering of responding was suspended, it were not observed any effects on the maintenance of the interlocking behavioral contingencies and aggregate outcome. Experiment 2 started without the ordering of participants responding, which was put in force after production of bonuses stability for five genarations was reached. The interlocking behavioral contingencies and the aggregate outcome weres selected and mantained throughout the experiment, without suffering any ruptures after the insertion of the ordering of participants responding. Thus, it was concluded that the ordering of participants responding didn t produce any observable effects upon the selection and maintenance of the interlocking behavioral contingencies and aggregate outcome / O objetivo deste trabalho foi avaliar os efeitos de um procedimento de ordenação do responder dos participantes sobre a seleção e a manutenção de contingências comportamentais entrelaçadas e do produto agregado pelas consequências culturais. Para isso, foram realizados dois experimentos com, 19 e 14 participantes, em sua maioria universitários da PUC-SP, de diversos cursos. A tarefa experimental, a qual foi apresentada e realizada utilizando-se um software de computador (Meta 3), foi realizada em grupo, três participantes de cada vez caracterizando uma geração. Ao final de cada geração o participante mais antigo era substituído por um novo participante, ingênuo em relação à atividade experimental, a qual consistiu em inserir números em espaços vazios na tela do computador. A relação entre os números inseridos pelos participantes e números apresentados pelo computador gerava pontos, a consequência individual; e a relação entre as somas dos números inseridos pelo participante e as somas dos números inseridos pelos outros participantes gerava bônus, a consequência cultural. Ao final da participação, cada participante recebeu R$0,01 por cada 10 pontos ou bônus produzidos, a título de ajuda de custos. O Experimento 1 começou com a ordenação forçada do responder dos participantes em vigor, e, posteriormente, foi retirada a ordenação. Os resultados indicam que houve seleção operante e das contingências comportamentais entrelaçadas e produto agregado com a ordenação do responder dos participantes e manutenção dos mesmos, e que quando a ordenação do responder foi removida, não se observou qualquer efeito na manutenção das contingências comportamentais entrelaçadas e do produto agregado. O Experimento 2 teve início sem a ordenação forçada do responder dos participantes, a qual foi colocada em vigor após a estabilidade da produção de bônus por cinco gerações. As contingências comportamentais entrelaçadas e o produto agregado foram selecionados e se mantiveram durante todo o experimento, não sofrendo qualquer ruptura após a inserção da ordenação do responder dos participantes. Concluiu-se, assim, que a ordenação do responder não produziu efeito observável sobre a seleção e a manutenção de contingências comportamentais entrelaçadas e produto agregado

Its main objective is to identify its dynamic processes of transformation, as well as strategies used by slaved Africans to both adapt to the "new world ", and to perpetuate the ties that bound them to Africa, a necessary step to resist colonial power embodied into oppression and violence. In addition to the seasonality of the period between Christmas and January 6, these black festivities share fragments of performative literacies , which inspite of their similarities and differences are revealing the contribution of African civilization in the Americas. We propose to "read" these festivities through, mainly, cultural practices, customs and the African body which in its displacement uploaded experiences and knowledge / Este trabalho acompanha a emergência de festas de protagonismo negro, de ocorrência no ciclo natalino, em regiões do Brasil e do Caribe, durante os séculos XVIII e XIX. O objetivo é identificar seus dinâmicos processos de transformação, bem como estratégias de adaptação ao novo mundo a que africanos escravizados, burlando a repressão e a violência do poder colonial, lançaram mão para perpetuarem os vínculos que os ligavam à África. Para além da sazonalidade do período, compreendido entre Natal e 6 de janeiro, essas festas negras partilham fragmentos de textos performativos , que em suas similaridades e diferenças são reveladores do aporte civilizacional africano nas Américas. Propomos ler essas festas privilegiando costumes, práticas e, principalmente, o corpo africano, que em seu deslocamento carregou experiências e saberes

Ce mémoire cherche à concevoir en théorie la dialectique socialisa-tion/individualisation à l’œuvre dans la formation et la transmission des goûts et pratiques culturels chez les jeunes adultes. L'analyse de dix entretiens conduits auprès de jeunes Montréalais âgés de 18 à 24 ans révèle que la socialisation sous l’égide de la famille et de l’école reste active sans être coercitive du fait qu’elle s'avère propice à la capacité des jeunes à se concevoir sous leur propre gouverne et à développer leurs propres goûts en matière de pratiques culturelles. Les pairs jouent également un rôle à cet égard, rôle amplifié par les moyens numériques. Les relations entre pairs génèrent une espèce de tension entre conformité au groupe et volonté d’être soi-même et de pouvoir agir à sa guise. Les nouvelles technologies d’information et de communication, quant à elles, se révèlent de nos jours sources de socialisation et d’individualisation en donnant accès à des « réseaux » en vertu desquels s’infléchissent les goûts et les préférences qui façonnent la pratique de la culture tout en permettant aux jeunes d’avoir les coudées franches pour les développer par eux-mêmes. / This dissertation seeks to conceptualize the socialization/individualization dialectic at work in the formation and transmission of cultural tastes and practices among young adults. The analysis of ten interviews, conducted with young Montrealers aged 18 to 24, reveals that socialization operating within the family and school remains active without being coercive, because it proves favourable to the aptitude of young people to define themselves autonomously and to develop their own tastes in cultural practices. Peers also play a role in this regard, a role amplified by digital means. Relationships between peers generate tensions between group conformity and willingness to be authentic and to act upon one’s behalf. New technologies of information and communication, furthermore, appear as a source of socialization and individualization by providing access to "networks" that inflect the tastes and preferences shaping the practice of culture, while simultaneously allowing young adults the freedom to develop themselves.

Corolaire de l'exode rural et de l'industrialisation, une attention au patrimoine local et à l'espace régional se fait jour en France à la fin du 19e siècle. Cet intérêt se manifeste en particulier à travers le renouvellement et le dynamisme de revues destinées à de nouvelles catégories sociales aspirant à une activité culturelle. Préfiguration du magazine, ces revues contribuent au sein des espaces français à définir des identités régionales. Elle permettent d'élargir les critères de patrimonialisation, auparavant cantonnés à l'histoire, à la littérature et à la philologie, et à démocratiser par la mise à l'honneur des traditions populaires, de la pratique personnelle des espaces (tourisme, environnement) et de leur approche esthétique. Elles tendent aussi à individualiser un rapport jusque-là communautaire aux territoires. Elles marquent enfin le renouvellement d'une vision du patrimoine à base d'héritage et d'atavisme, au profit d'une notion plus moderne de patrimoine d'élection, notamment dans le cadre de l'évasion par rapport au quotidien. / Corollary of the rural exodus and the industrialization, a focus on the local heritage and on the regional area emerges in France at the end of the 19th century. This concern manifests itself through the regeneration and the dynamism of journals intended for new social groups yearning for cultural activities. Prefiguration of the magazine, these journals contribute, inside of French Regions, to the definition of the regional identities. They enable the expansion of the making of heritage, previously limited to history, literature and philology, and its democratization, thanks to the valorization of popular traditions, to the private practice of the areas (tourism, environment) et to its esthetical approach. They also seek the individualization of a so far communal relation to territories. Finally, they rejuvenate a conception of heritage based on legacy and atavism, in favor of a more modern concept of chosen heritage, especially in the context of escaping daily life.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The research of Family Amaros is, in some sense, the continuity of the master thesis, entitled The Caretagem as cultural practice: faith, blackness and revelry in Paracatu, MG(1960-1980) and, consequently, the induced understand its displacement relative to a neighborhood on the outskirts of the city of Paracatu and understand their wiles and cultural resistance, especially with regard to the struggles and conflicts that have undertaken the process of resuming possession of their lands and farm Pituba. In this sense, this research on the family of Amaros aimed to deepen their ritual context, which aims to establish a dialogue that goes beyond a simple reading of the daily life they represent, because the trajectory envisioned an understanding of family and kinship network woven from cultural shaped face and survive the social and political issues experienced. In vieis, this agenda is the political struggle for social rights of the family land located on the farm of Amaros, Pituba, from which they were expropriated from the year 1940. In this political process was evidence the persistence of the values and traditions of African descent enrolled in a memory that moved to the urban periphery recreate their culture, their way of life, combining the family around their celebrations, sociability, arts and craft activities as a way of living maintain their cultural identity. From this point of view, we conceive the political struggle for recognition of their land and social rights embedded in their daily lives for their popular cultural practices, hence, the focus not only on their movement around the Palmares Cultural Foundation and the Institute for Black Speech, but also the set of symbolic representations that protect their cultural identity through a social memory in continuous recreation / reinvention. / A pesquisa - Família dos Amaros - é, em algum sentido, a continuidade do trabalho de mestrado, intitulado A Caretagem como prática cultural: fé, negritude e folia em Paracatu-MG (1960-1980) o que, por consequência, nos induziu a compreender o seu deslocamento familiar para um bairro da periferia da cidade de Paracatu. Assim como nos permitiu entender as suas astúcias e resistências culturais, especialmente no que diz respeito às lutas e conflitos que têm empreendido no processo de retomada e posse de suas terras da fazenda Pituba. Nesse sentido, a pesquisa sobre a família dos Amaros objetivou aprofundar seu contexto ritualístico, num diálogo que pretende ir além de uma leitura do simples cotidiano por eles representado, já que a trajetória vislumbrada passa pelo entendimento da rede de parentesco familiar e cultural tecida como forma de enfrentar e sobreviver às questões sociais e políticas vivenciadas. Neste viés, está em pauta a luta política pelos direitos sociais da terra da família dos Amaros situada na fazenda Pituba, que lhes foi expropriada a partir dos anos de 1940. Nesse processo político, evidencia-se a persistência dos valores e tradições inscritos numa memória afrodescendente que, deslocada para a periferia urbana, recria sua cultura, sua forma de viver, aglutinando os familiares em torno de suas festas, sociabilidades, atividades artesanais e artes de viver como forma de manter sua identidade cultural. Desse ponto de vista concebemos a luta política pelo reconhecimento de suas terras e direitos sociais entranhadas no seu cotidiano pelas suas práticas culturais populares, daí o enfoque não só na sua movimentação em torno da Fundação Cultural Palmares e do Instituto Fala Negra, mas também no conjunto de representações simbólicas que resguardam sua identidade cultural por meio de uma memória social em contínua recriação/reinvenção. / Doutor em História

Goiânia, Brasília and Palmas. The proposition is that the dialectical relationship between the norm and the life, through work and social-cultural practices, promotes landslidings of meaning both in form and content of the urban spaces, thus, provoking a new (Dis)order in these cities. The term “not welcomed subjects” was coined by the author of this paper on her master’s degree dis sertation as a way of referring to the capital Goiânia builders, once that, despite these workers represented a bigger contingent on the city building process, there wasn’t even a reserved space for them on the original planning. This fact allowed the relationship assessment of what was once imputed to the workers, the time elapsed on the city building wasn’t counted as well as the right to live over the edifications they crafted. This phenomenon, that has also happened in the city building of Brasília and Palmas, goes on until today, revealing that the not welcomed subjects on cities planned spaces are not only the builders. Another huge contingent of workers is added to the “not welcomed” group forced out of their homes for numerous reasons like, expelling from the countryside, lack of work, housing and better life perspective, etc., these individuals migrated to Goiânia, Palmas and Brasília hoping to find better living conditions. Another important assessment is that these cities were built and managed wit hin the bounds of capitalist development. They are cities initially planned, as claimed by some authors and researchers, by and for the capital. However, despite agreeing with the socio -spatial analysis that come from these precepts and also understanding the hegemonic financier and market driven logic through the capital-cities urban spaces configuration, we believe that they are insufficient to comprehend the development of these cities urban areas, once that, the final product of the capital-work relationship is privileged, while the not welcomed subjects’ struggles for surviving and fixing themselves in the new city is ignored. Therefore, we add to the relationships studied here the symbolic, political and social meanings. There is a spatial living that cannot be ignored; it’s within it that the not welcomed subjects’ movement against the logic of hegemonic capital is acknowledged. It’s over this space that the dialectical contradictions are revealed: the dialectic between the conceived and perceived spac e and the lived one; between the historical time and the social one; between alienation and creation; between frustration and possibility; between domination and insurgency; demonstrating that human beings cannot be totally alienated, through struggles, creations, changes, they resist and (re) exist. When doing it, they break the established order and portray a new ( Dis)order, which, in one way or another, will be materialized in the urban areas and alter its form and contend. And it’s exactly within this movement that a transforming praxis can be glimpsed. / O objetivo principal dessa tese é analisar o processo de espacialização dos sujeitos não desejados nas cidades-capitais planejadas do Cerrado: Goiânia, Brasília e Palmas. A proposição é que a relação dialética entre a norma e vida, por meio do trabalho e das práticas socioculturais, promove deslizamentos de sentidos nas formas e nos conteúdos dos espaços urbanos provocando, assim, uma nova (Des)ordem nestas cidades. O termo 'sujeitos não desejados' foi cunhado pela autora em sua dissertação de mestrado para referir -se aos trabalhadores construtores da cidade de Goiânia, uma vez que, apesar de estes trabalhadores representarem o maior contingente envolvido no processo de construção de Goiânia, não havia sequer um espaço a eles reservados no plano original. Tal fato levou à constatação sobre a relação que se tentou imputar entre a temporalidade da construção destas cidades e o direito destes operários de nelas residirem, ou melhor, o direito de usufruírem de suas obras nas/das cidades que contribuíram para edificar. Este fenômeno, que também aconteceu no processo de construção de Brasília e Palmas, perdura até os dias de hoje, revelando, assim, que os sujeitos não desejados nos espaços planejados destas cidades hoje não são apenas os trabalhadores construtores. Acrescenta-se a este grupo um enorme contingente de trabalhadores que impulsionados por diversos fatores, como a expulsão do campo, a falta de trabalho, de moradia e de perspectiva de vida digna em suas cidades etc., migram para Goiânia, Palmas e Brasília na “esperança” da possibilidade da perspectiva de trabalho e de melhores condições de vida. Outra constatação importante é que estas cidades foram construídas e são geridas dentro da lógica do modo de produção capitalista. São cidades inicialmente planejadas, como anunciam alguns autores e pesquisadores, pelo e para o capital. Todavia, apesar de comungar com as análises socioespaciais que partem destes preceitos e compreender a hegemonia desta lógica financista e mercadológica no processo de configuração dos espaços urbanos, entendemos que eles são insuficientes para compreender a formação dos espaços urbanos dessas cidades-capitais, uma vez que ao privilegiar o produto final da relação capital-trabalho, ignoram a luta dos sujeitos não desejados para se fixarem nesta cidade. Deste modo é que acrescentamos as relações e os seus significados simbólicos, políticos e sociais. Há um espaço vivido que não pode ser desconsiderado. É nele que se percebe o movimento dos sujeitos não desejados contra a lógica hegemônica do capital. É nele que as contradições, consequentemente, a dialética, entre o espaço concebido, o espaço percebido e o espaço vivido; entre o tempo histórico e o tempo social, econômico; entre alienação e criação; entre frustração e possibilidade; entre dominação e insurgência irão revelar -se e demonstrar que o ser humano não é passível de alienação total. Ele, o ser humano, luta, cria, modifica, enfim, resiste e (Re)Existe. Ao fazer isso, rompe a ordem estabelecida e cria uma nova ( Des)ordem, (des)ordem esta que, de uma forma ou de outra, irá materializar -se nos espaços urbanos e alterar a sua forma e o seu conteúdo. É exatamente neste movimento que se pode vis lumbrar a possibilidade da práxis transformadora.

Its building was a strategy of power that sought, in a regional context, to link the productive regions of the State of Goiás, mainly to the south and southwest regions, and to end the old family oligarchies and, in a national level, to bring the country to a new pattern of capitalist production; that means, it was the investment in the process of expansion of the capitalist system of production through the territory modernization. Thus, the city appears with well defined interests and political/economic functions. To make this project feasible, many resources were used, since political and economics agreements till marketing campaigns with the aim to promote the need for modernization. The new was the way. To reach this, nothing better than a new urban plan to retract, through the curves and lines, the progress, the growth and the integration of the hinterland in modern times. The Goiás of "Tropas and Boiadas" (Troop and Drove) by Hugo de Carvalho Ramos, should subjugate to the Treaty of Versailles of Atílio Correia de Lima. This attempt to overlay a culture on the other produced contradictions, considering that it wasn t take into account - or at least the importance was not understood - the fact that who composes a city are the social costumers. Even if a city plan is carefully prepared and agreed politically and economically, its deployment will carry the influence of several social groups that will compose it, fact that will cause the change of the meanings. Thus, it can be observed the creation of a myth and/or urban phenomenon on the modern and planned city in countries land which is based on an ideology of the subjetc city . To understand these assertions is necessary to break with the fragmented way of thinking the city, which conduces to the construction of a critical sight of the space that allows to come across the local and the global, the contradictions between rule and life, the interference of the cultural practices in an urban planning; anyway, that allows an integrated analysis in which theory and practice, perception and reason are complementary in order to understand through the landscape and through the social representation and daily life how the social and cultural practices, material and immaterial, incured directly on the appearance and on the content of Goiânia s territory in the period of 1930 to 1950, observing the changes or even the disfigurement of the original plan, which involves the conflict between rule and life / Goiânia foi a primeira cidade planejada do Brasil no século XX. A sua edificação era uma estratégia de poder que buscava, no âmbito regional, articular as regiões produtivas do Estado de Goiás, principalmente às regiões sul e sudoeste, bem como dar fim às antigas oligarquias familiares e, no âmbito nacional, adequar o país a um novo ritmo de produção capitalista, ou seja, era a investida do processo de expansão do modo de produção capitalista via modernização do território. Sendo assim, a cidade já surge com interesses e funções políticas e econômicas bastante definidas. Para que esse projeto se viabilizasse, inúmeros foram os recursos utilizados, desde acordos políticos, econômicos a campanhas publicitárias que tinham como objetivo difundir a necessidade de modernização. O novo era o caminho. Para isso, nada melhor que um plano urbanístico inovador que retratasse, por meio das curvas e traços, o avanço, o crescimento e a inserção do sertão nos tempos modernos. O Goiás das Tropas e Boiadas , de Hugo de Carvalho Ramos, deveria se render ao traçado de Versalhes de Atílio Correia Lima e Cia. Essa tentativa de sobreposição de uma cultura sobre a outra gerou contradições, pois não se levou em conta ou pelo menos não enxergou a importância o fato de que quem compõe uma cidade são os sujeitos sociais. Por mais que um plano de cidade seja minuciosamente elaborado e acordado política e economicamente, a sua implantação terá a influência dos diversos grupos sociais que irão integrá-la, fato que acarretará deslizamentos de sentidos. Assiste-se, assim, à criação de um mito e/ou fenômeno urbano em torno da cidade planejada e moderna em terras sertanejas, embasado por uma ideologia da cidade como sujeito. Para compreender essas assertivas é necessário romper com o modo fragmentado de pensar a cidade, o que leva à construção de um olhar espacial que, por sua vez, permite deparar com o local e o global, com as contradições entre norma e vida, com as interferências das práticas socioculturais no planejamento urbano. Enfim, possibilita uma análise integrada em que teoria e prática, razão e percepção se complementam, na busca de compreender, por meio da paisagem, da representação social e do cotidiano, como as práticas socioculturais, materiais e imateriais, incidiram diretamente na feição e no conteúdo do território goianiense no período de 1930 a 1950, observando as transformações ou, até mesmo, a desconfiguração do plano original, que implica o conflito entre a norma e a vida.

En dépit du rôle crucial qu’elles peuvent jouer dans les appropriations de langues et de cultures, les pratiques culturelles plurilingues restent peu documentées. Cette thèse en didactique des langues et des cultures étudie les pratiques plurilingues de lecture de livres d’adultes vivant en Europe de l’Ouest. Elle recourt également à des données et des outils relevant de la sociolinguistique, la sociologie, la littérature, l’histoire et l’anthropologie. Elle s’appuie sur des entretiens menés avec des lecteurs et des observateurs résidant en Catalogne, en Île-de-France, au Pays basque français et en Suisse romande, ainsi que des questionnaires remplis par des apprenants de français langue étrangère dans une université parisienne.Cette exploration des pratiques de lecture en plusieurs langues met au jour la continuité des pratiques plurilittéraciées au fil de l’histoire, mais aussi les impacts de la mondialisation, dans sa forme actuelle, sur l’incessante construction des répertoires individuels. Elle montre l’importance des rapports de force linguistiques et culturels dans les usages de l’écrit. L’analyse des finalités, supports et modalités des lectures déclarées, sans oublier leurs dimensions affectives et identitaires, fait ressortir l’hétérogénéité et la variabilité des pratiques culturelles plurilingues. Les propositions pédagogiques et théoriques qui en découlent encouragent une plus grande adaptation des activités de lecture en classe de langue-s aux réalités des pratiques autonomes, ainsi qu’une meilleure prise en compte, dans les recherches didactiques, de la complexité des plurilinguismes et des pluriculturalismes individuels. / Despite their key role in language acquisition and learning, little is known about plurilingual cultural practices outside the educational context. This PhD research in Applied Linguistics investigates the plurilingual book-reading practices of adults living in Western Europe. This work uses data, theoretical and methodological constructs from Language Education, Sociology, Literature, History and Anthropology. The study is based on in-depth interviews of readers and observers carried out in Catalonia, Ile-de-France, French Basque Country and Western Switzerland, and questionnaires collected from foreign university students in Paris. This exploration of reading habits in several languages reveals the continuity of pluriliteracy practices throughout History, but also the impacts of globalization –in its current form– on individuals’ linguistic and cultural repertoires. It shows the influence of power relations between cultures and between languages on the literacy uses. The analysis of the aims, circumstances and materials of reading practices, as well as of their emotional and identity issues, highlights the heterogeneity and variability of plurilingual cultural practices. The resulting pedagogical and theoretical recommendations support a greater adaptation of classroom reading activities to the realities of autonomous practices, and a better consideration of the complexity of individual plurilingualism and pluriculturalism in language learning studies. / A pesar de su papel en las apropiaciones de lenguas y culturas, las prácticas culturales plurilingües están poco documentadas. Esta tesis doctoral en didáctica de las lenguas y culturas estudia los hábitos plurilingües de lectura de libros de adultos que viven en Europa occidental. Utiliza datos y herramientas metodológicas de varias disciplinas, como la sociología, la sociolingüística, la literatura, la historia y la antropología. Se basa en entrevistas con lectores y observadores realizadas en Cataluña, Île-de-France, País Vasco francés, Suiza romanda, y cuestionarios completados por estudiantes de francés como lengua extranjera en una universidad parisiense. Esta investigación arroja luz sobre la continuidad de la prácticas de literacidad plurilingües a lo largo de la Historia, así como sobre los efectos de la globalización, en su forma actual, en la construcción continua de los repertorios individuales. Muestra también la influencia de las relaciones de poder lingüísticas y culturales en los hábitos de lectura. El análisis de las finalidades, los soportes y las modalidades de las lecturas declaradas –sin olvidar sus dimensiones afectivas e identitarias– destaca la heterogeneidad y la variabilidad de las prácticas culturales en varios idiomas. Las propuestas pedagógicas y teóricas consiguientes animan a adecuar más las actividades de lectura en clase de idioma-s a las realidades de las prácticas autónomas, y a tener más en cuenta, en los estudios de didáctica, la complejidad de los plurilingüismos y pluriculturalismos individuales.

Que signifie aimer une « série télé » aujourd’hui ? Ou, selon une formulation plus pragmatiste, que font faire les séries à leurs spectateurs ? Pour répondre à ces questions, cette thèse invite à se démarquer du paradigme de la réception – lequel fournit la majorité des études sur le sujet – et explorer les ressorts et contours de la pratique des séries. Il s’agit d’étudier les activités concrètes dans lesquelles s’engagent les amateurs, la façon dont se tissent leur attachement aux séries, les ingrédients de ce tissage, les appuis et prises matériels, techniques et relationnels de cet attachement. Ce travail montre que la pratique spectatorielle ne s’arrête pas au seul moment du visionnage, lorsque l’individu est devant son poste, mais s’étend à l’ensemble des activités, des temps et des espaces au cours desquels celui-ci entre en relation avec une série. À partir d’une quarantaine d’entretiens approfondis et de l’examen des principaux relais sociotechniques et médiatiques des séries, la thèse se propose de suivre les amateurs dans leurs pratiques quotidiennes, du visionnage et de la conservation des séries à leurs échanges conversationnels, en passant par les procédures d’information et de découverte, d’approvisionnement et de partage de contenus. Autant d’activités, non pas seulement « réceptives », mais réflexives, corporées, instrumentées et collectives, qui permettent d’apprécier la diversité des formes d’attachement des « sériphiles » à ces objets singuliers. / What does it means to love a "TV series" nowadays? Or, to use a more pragmatic formulation, what do television series make their viewers do? To answer these questions, this thesis invites the reader to move beyond the paradigm of reception – on which the majority of studies in the field build upon - and explore the remits and contours of the practice of series. The aim is to study the practical activities undertaken by amateurs, how their attachments to the series are built, the ingredients of this attachment, and the material, technical and relational means of this attachment. This work shows that spectators' practices do not stop at the moment of viewing, when the individual is in front of his post, but extends to all activities, times and spaces through which an individual connects to a series. Drawing upon forty in-depth interviews and an examination of the ways in which series are socio-technically mediated, the thesis proposes to follow amateurs in their daily practices, from the viewing and storage of series, to their conversational exchanges, as well as through the procedures of information and discovery, procurement and sharing of content. All these activities are not only "receptive". As the thesis shows, they are at once reflexive, embodied, instrumented and collective, and they reveal the diversity of attachments of the "seriephiles" to these singular objects.

La symbiose mycorhizienne à arbuscules, dont l’apparition est conjointe à celle des plantes terrestres il y a 460 millions d’années, est une association mutualiste à bénéfices réciproques qui s’instaure entre la plupart des plantes terrestres, y compris celles cultivées, et des microorganismes ubiquitaires du sol que sont les champignons mycorhiziens à arbuscules (CMA, phylum des Glomeromycota). Lors cette symbiose, le fort potentiel d’amélioration de la nutrition minérale des plantes, et donc de la production végétale, est un atout dans le contexte mondial actuel d’augmentation de la demande de la production agricole. Afin d’optimiser les services écosystémiques des CMA dans les écosystèmes et en particulier les agroécosystèmes, la maîtrise de cette symbiose en ingénierie écologique nécessite la compréhension des mécanismes complexes qui régissent la dynamique de cette symbiose dans ces écosystèmes. Pour cela, nous avons étudié la diversité des communautés et des populations de CMA dans les agroécosystèmes à différentes échelles spatiales et sous l’influence de différentes pratiques culturales par des techniques d’empreintes moléculaires: séquençage haut-débit et polymorphisme de longueur de fragments de restriction. Les résultats obtenus montrent que la structuration de la diversité des CMA est influencée par le type d’usage de sol (prairie vs. culture), les pratiques culturales (retournement du sol, fertilisation et système de culture) ainsi que par les facteurs abiotiques (e.g. pH du sol). En conclusion, ces différents facteurs sont à prendre en compte dans l’optimisation des services écosystémiques des CMA. / The arbuscular mycorrhizal symbiosis, which appeared at the same time as land plants, 460 million years ago, is a mutualistic beneficial association between most land plants, including those cultivated, and arbuscular mycorrhizal fungi (AMF). AMF, from the Glomeromycota phylum, are widespread soil microorganisms needing a photosynthetic host to complete their life cycle (obligate symbionts). The great potential of plant mineral nutrition improvement and crop production increased during this symbiosis, make AMF an asset in the context of an increase in the demand of world food crop production. The control of that symbiosis by ecology engineering in order to improve ecosystem services, especially in agroecosystems, needs to better understand the mechanisms regulating its dynamic. Therefore, we studied community and population diversity of AMF under influences of different agricultural practices at several spatial scales using genetic fingerprinting methods: high-throughput sequencing and restriction fragment length polymorphism. Results show that AMF diversity is structured by land use type (grassland vs. arable fields), cultural practices (soil disturbance, fertilizations, culturing systems) as well as environmental factors (e.g. soil pH). In conclusion, those different factors have to taken in account in AMF ecosystemic service managing.
