Notre thèse évoque les usages d'Internet des préadolescents âgés de 11 à 14 ans, dans toute leur complexité d'une manière anthropologique et ethno-qualitative. D'une part, elle présente une démarche scientifique appliquée et ses principes en se focalisant sur le courant méthodologique des Visual Methodologies, et plus particulièrement sur les méthodes visuelles participatives utilisées durant l'étude dans deux collèges publics bordelais. Et d'autre part, elle fournit l'analyse des résultats de cette étude afin de démontrer comment, grâce à la création de collages et de dessins et aux entretiens menés avec la technique « dessin/collage-élicitation », les préadolescents ont pu construire un modèle métaphorique de leur lien avec Internet. Notre thèse contribue à la compréhension des dynamiques sociales, culturelles et identitaires qui se créent à travers les dispositifs en ligne et se manifestent chez le public des préadolescents. Nous examinons la façon dont le public en question, à travers ses interactions numériques, comportements, routines, jeux, construit un espace culturel en ligne et comment, à leur tour, les différentes formes d'activités et d'expression influencent leur monde : leurs relations, leur identité et leur quotidien. / This thesis discusses preteens' (aged from 11 to 14 years old) uses of the Internet in all their complexities and in anthropological and ethno-qualitative ways. Firstly, it presents a scientific approach and it's principles by focusing on the Visual Methodologies, especially on the participatory visual methods used during the study In two public schools in Bordeaux. Secondly, it provides the analysis of the results of this study to demonstrate how, through the creation of collages and drawings, and interviews with the technical "drawing/collage-elicitation", preteens were able to build a metaphorical model of their relation with the Internet. This thesis contributes to a better understanding of the social and cultural dynamics between the identity created online and the one developed in the preteens' ordinary lives. We examine how this public, through its digital interactions, behaviours, routines, and games, builds a cultural space on the Internet and how the different forms of activities and expressions influence their world: their relationships, their identities and their lives.

Depuis quelques années le recours à l’enneigement artificiel est de plus en plus courant dans les stations de ski des Alpes mais également dans les autres massifs français et étrangers. Cependant la production de neige nécessite l’utilisation d’un volume d’eau important, souvent pompé dans les réserves d’eau potable, les rivières, les nappes phréatiques, ou bien dans les réserves collinaires, elles-mêmes alimentées par captage des eaux de ruissellement. Or l’enneigement n’est pas le seul usage de l’eau dans les stations de sports d’hiver, et ce nouveau besoin concerne la saison hivernale lors des étiages des cours d’eau et des besoins pour les diverses activités. Depuis quelques années, cette technique fait l’objet de nombreuses controverses au sein de la communauté scientifique, politique et des populations locales, car les volumes d’eau pompés sont particulièrement importants. Notre recherche s’appuie sur des enquêtes auprès des acteurs impliqués, des observations de terrain et des mesures, à différentes échelles de travail. Deux modèles de production de neige sont confrontés : Avoriaz (France) et Champéry (Suisse). Les impacts des usages sur le fonctionnement hydrologique du bassin versant de la Dranse de Sous-Saix, sur le domaine d’Avoriaz, sont aujourd’hui limités et dans les deux stations la ressource est actuellement suffisante pour satisfaire tous les besoins. A ce jour les situations de pénuries d’eau et de conflits autour de la ressource sont rares, et sont dues à des problèmes de gestion. Un ensemble de propositions inspirées d’initiatives locales pour une meilleure gestion de la production de neige et des usages de l’eau a été proposé. / For some years now the use of artificial snow has become increasingly frequent in Alpine skiing resorts as well as in the other French and foreign massifs. Nevertheless, snowmaking calls for a large amount of water, which is often pumped from drinking water reserves, rivers, groundwater tables or else from hill water reserves, themselves supplied from surface water capture. This relatively recent practice, added to the different activities already present, is of concern for the local populations and environmental associations. For several years now, this technique has been the subject of numerous controversies within the scientific and political community and local populations. As things stand, the work performed by researchers and, more particularly, geographers is thin on the ground, because the volumes of water pumped are particularly important. Our research is based on interviews whit those involved in snow production, field observation and measures. Two model of artificial snow are confronted : Avoriaz (France) and Champéry (Switzerland). The impacts of the uses on the hydrological functioning of the Dranse de Sous Saix catchment area, in Avoriaz’s area are now limited and in both resorts, the resource is currently sufficient to satisfy all the needs. At the present time water shortages or conflicts involving the resource are unusual, and are thus due to management problems. A set of proposals inspired local initiatives for a better artificial snow management and water uses management have been proposed.

The Master's thesis is focused on the Slovakian TV show Nákupné maniačky and its' audience. The purpose of the thesis is to reveal the motivations leading to watching this show and to explore, whether the viewers perceive the show as a fashion show which allows them to draw inspiration, or rather as a reality show that should entertain them. The theoretical part introduces the concepts as audience, uses and gratifications and reality show genre. The final analysis of the acquired data is based on these terms but it aims to invent a new hypothesis. The second part is devoted to the research that is based on a qualitative method of a grounded theory. Required data was collected by the semi-structured interviews with viewers divided into two age categories. The result of categorizing data indicates that for all viewers the main motivation for watching the show is to have fun. Participants reported enjoying the program because of its' humour, while fashion plays an irrelevant role. The findings also show that participants are aware of interventions of production and they explained manipulating competitors as a strategy of the broadcasters to entertain audience and attract more viewers. This assumption was confirmed by an informant interview with one of the creators of the show.

This thesis delineates a problem with researching and theorizing about craft. It argues that traditional epistemologies and academic conventions have not given sufficient recognition or value to the epistemologies and lived experiences of craft practitioners, and that they have served to obscure the centrality of practice to meaning. Consequently, there is a need to make craft practice and practitioners accounts more accessible to researchers. It proposes and tests a method using video recordings of practitioners working and interviews with practitioners in the loci of their practice as a tool, which, it is contended, provides a rich source of data about practice so that theory can be generated in a grounded way from practice. It is argued that the idea of 'the crafts' is a late twentieth-century construct, but it has its roots in an ideological and intellectual tradition, expressed in the writing of the nineteenth-century Arts and Crafts movement. That writing was primarily concerned with the organisation and ownership of labour, with the moral and social purpose of art, and with creativity, given expression through the making process. Since the 1970s, we have seen the emergence of a legitimizing infrastructure for 'the crafts' as a category, separate from but relating to art and design. The institutional craft world attempted to distance itself from Arts and Crafts ideology and from associations with the rural and the traditional. A key feature of the institutional discourse has been attempts to establish a definition of 'craft' as a singular thing within the sphere of its influence. The thesis argues that the problematic relationship between theory and practice stems partly from this disjunction between the institutional craft world and the ideological and intellectual heritage of William Morris and his followers. It demonstrates that data gathered using the method proposed could make a positive contribution to emergent discourses on craft as experience. Within the complexity of the data gathered using the proposed method, concepts and patterns are consistently observed. The subjects are seen to be engaged in self-determined activities which are nevertheless socially situated. They are using knowledge that is embodied and enacted, and which evolves through the practice. The data shifts the focus of critical attention from the objects that are being produced and onto the practice itself. This research method makes craft practices available to the researcher and opens up a critical focus on crafting as intrinsically rewarding activities that are facilitated by learned, embodied competence, based in shared values and standards.

This work takes off in earlier studies concerning motivational factors to interact in various social media in relation to societal and political discussions. The aim for this study is to garner a deeper understanding about how users on Twitter are motivated to take part in debates beneath the hashtag #svpol. Also, this work contributes with the personal experience of entering the Twittersphere as a new user without the capital of trust or knowledge prerequisite to the participation in the community of #svpol. Through semi-structured interviews six respondents shared their experiences of political dialogue on Twitter. Further, this study presents a new form of gathering data by using Twitter as a channel for textual responses through the function of Direct Messages where 3 respondents answered in text. The results presented confirms earlier theory in some respects regarding motivational factors to engage in political commentary and debate on Twitter. Also, this study presents nuances which can be recognized as pre-dispositioning motivational factors addressed in earlier research. The respondents in this work show differences in their social orientation displaying both relation orientation and antagonistic features in the community of #svpol. Their motivation and gratifications differ, and the result are discussed and concluded in the final chapter. This study does not generalize by the findings presented, rather it describes a small window of the community of #svpol and political commentary on Twitter. Rather than posing any absolute truths or widely held conceptions, this study contributes by giving some depth to the notion of nine Twitter users and their perception of the activity beneath #svpol on the Twitter platform. This work also shines light hardships which a researcher might encounter on the way to a qualitative approach to Twitter users in a general, largely anonymous, network within a national setting.

Esta dissertação oferece um estudo sobre a formação territorial do município de Campinas/SP e seu planejamento urbano partindo de instrumentais teórico-metodológicos que incluem a cartografia temática, a periodização e a história como um recurso de método. Estes, aliados a um conjunto de conceitos e categorias como o lugar, o território usado, os eventos e a solidariedade, têm por finalidade identificar qual a contribuição do planejamento urbano para os atuais usos do território. O que se nota é que ele tem seguido o velho manual do planejamento estratégico empresarial que importa modelos de outras correntes de planejamento, alheias ao lugar estudado, visando sua inserção no mundo competitivo da globalização. Tal fato é traduzido pela intensa criação de loteamentos e de fluidez no território, de modo que ele deflagra usos cada vez mais corporativos e setoriais que mutilam o território e sua sociedade, social e espacialmente. Também nos dedicamos em refletir sobre o papel que Campinas exerce dentro da rede urbana paulista e nacional devido às suas inúmeras funções e por abrigar um grande contingente de empresas e instituições hegemônicas paralelamente à proliferação das desigualdades socioespaciais. / This masters dissertation studies the territorial formation of Campinas/SP and its urban planning by the use of a theory-methodological instrumentals which includes the tematic cartography, the periodization and the history as a method resource allied with a group of concepts and cathegories as well as the place, the used territory, the events and the solidarity that leads to figure out what is the contribution of the planning for the nowadays uses of territory. We have seen that it has followed the old company strategic planning manual and it imports models from others planning currents from different world places to provide its insertion on the competitive world of globalization. This fact is translated by the several creation of urban lots and fluidity in the territory which shows uses every time more corporative and setorial that mutilate the territory and its society, social and spacially as well. We also dedicate in reflecting about the role that Campinas fulfills in a regional and national urban chain due to its several functions and for including a very big uncertainty of common knowledge companies and institutions parallely to the expansion of social spacially inequalities.

Este trabalho teve como objetivo comparar a eficiência de dois dispositivos intravaginais de progesterona (P4) comerciais constituídos de matriz de silicone, um contendo um grama (g) de progesterona (Cronipres® de 3usos, Biogénesis Bagó, Argentina) e outro contendo 0,558 g de P4 (Cronipres® Mono Dose M-24, Biogénesis Bagó, Argentina). O presente estudo foi dividido em três experimentos: O primeiro comparou a cinética de liberação de P4 (Teste in vitro). O segundo, avaliou as concentrações plasmáticas de P4 em vacas ovariectomizadas (Teste in vivo). No terceiro, vacas multíparas ciclícas passaram por um protocolo de sincronização da ovulação para IATF, onde foi avaliada a dinâmica folicular, desde a colocação do implante no D0, até o momento da inseminação (Dinâmica folicular). Nesse experimento as concentrações séricas de P4 foram dosadas nos dias 6, 7 e 8 do protocolo de IATF. No experimento In vitro supracitado, os dois dispositivos, foram alocados em duplicata, no dissolutor de comprimidos, o qual continha álcool e água na proporção de 60:40. Amostras foram colhidas nos seguintes momentos: 2min, 24, 48, 72, e 96 horas. As quantidades de P4 foram dosadas por Cromatografia Líquida de Alto Desempenho (HPLC). Para quantidade acumulada de P4, segundo dispositivo, em função do tempo, houve interação tempo*tratamento (P=0,0002). A quantidade de P4 diferiu entre os dois dispositivos testados e também em relação ao tempo (P<0.0001). Houve diferença estatísitica, nos tempos 2min, 72 e 96 horas. As equações que descrevem as quantidades liberadas são: dispositivos Cronipres® 3 usos Y= 62,396x + 175,70 (R2 = 0,99) Cronipres® Mono Dose Y= 53,314x + 127,7(R2=0,98). No experimento in vivo, 8 vacas ovariectomizadas foram divididas em dois grupos, metade recebeu o Cronipres® de 3 usos e a outra metade recebeu o Cronipres® Mono Dose durante 11 os dias de tratamento. Foram colhidas amostras nos tempos 0 (colocação do dispositivo ), 2, 4, 8, 12, 24, 48, 96, 144, 192, 216, 240 e 264 horas. Foram comparados os teores plasmáticos de P4, por espectrometria de massas no laboratório Thomson da Universidade de Campinas (UNICAMP). Houve efeito de tratamento e de tempo (p < 0,05), entretanto, não houve efeito de tempo (p > 0,05). No terceiro experimento, 20 vacas multíparas cíclicas foram submetidas a um protocolo de sincronização da ovulação. Os animais receberam 2 mg intramuscular (IM) de Benzoato de Estradiol . Metade do grupo (n=10) recebeu um dispositivo intravaginal de P4, Cronipres® 3 usos, e a outra metade (n=10) recebeu o Cronipres® Mono Dose M-24. No D8 procedeu-se a retirada do implante e aplicação IM de 150 g de D-cloprostenol . No D9, todos os animais receberam 1mg IM de Benzoato de estradiol . Foi realizado o escaneamento dos ovários por ultrassonografia a cada 24 horas, do momento da inserção do dispositivo até à retirada no D8. A partir da indução, todas as vacas tiveram seus ovários escaneados e mapeados a cada 12 horas, durante 4 dias. Coletas de sangue foram efetuadas nos dias seis, sete e oito do protocolo para comparar as concentrações plasmáticas de P4 antes da retirada do dispositivo. Foram avaliadas as variáveis, início da nova onda de crescimento folicular, diâmetro do folículo préovulatório (de forma retrospectiva) e momento da ovulação pelo teste qui quadrado. Os dados de ovulação, foram submetidos à análise de regressão logística, pelo PROC MIXED e os dados de desenvolvimento folicular, pelo PROC LOGISTIC (SAS, versão 9.3). Não houve diferença no início da nova onda de crescimento folicular, diâmetro do folículo pré-ovulatório e taxa de ovulação (P>0,05). Houve uma tendência de antecipação da ovulação (P=0.06), das vacas do grupo cronipres Mono Dose, uma vaca desse grupo antecipou a ovulação em cerca de 36 h.Mesmo apressentando diferenças estatísticas nos testes in vítro e in vivo, os animais tratados com dispositivo de 0,558 gramas apresentaram padrão de desenvolvimento folicular semelhante ao grupo tratado com o dispositivo de 1g. / This study aimed to compare the efficiency of two commercial intravaginal progesterone (P4) devices consisting of silicone matrix, containing 1 gram (g) of progesterone (Cronipres of 3uses ®, Biogenesis Bagó, Argentina) and another containing 0.558 g P4 (Cronipres ® Mono Dose M-24, Biogenesis Bagó, Argentina). This study was divided into three experiments: The first compared the kinetics of release of P4 (in vitro test). The second evaluated the plasma concentrations of P4 in ovariectomized cows (in vivo test). In the third, multiparous cyclical cows passed a complete protocol where TAI was evaluated follicular dynamics, since the placement of the implant in D0, until the time of insemination (follicular dynamics) and serum concentrations of P4 before removing devices (follicular dynamics). In vitro experiment above, the two devices were placed in triplicate in dissolver of tablets, which contained alcohol and water in the ratio of 60:40. Samples were collected at the following times: 2min, 24, 48, 72, and 96 hours. The amounts of P4 were measured by High Performance Liquid Chromatography (HPLC). To cumulative amount of P4, the second device as a function of time, treatment time * significant interaction (P = 0.0002). The amount of P4 differed between the two implants Cronipres ® and also in relation to time (P <0.0001). There were differences in the times 1, 4, 5. The equations that describe the quantities released are Cronipres device 3 uses ® Y - = 175.70 + 62.396 x (R2 = 0.99) Cronipres Dose ® Mono Y = 53.314 x + 127.7 (R2 = 0.98). In the in vivo experiment, 8 ovariectomized cows were divided into two groups, half received Cronipres ® 3 uses the other half received the Cronipres ® Mono Dose for 11 treatment days. Samples were collected at 0 (implant placement), 2, 4, 8, 12, 24, 48, 96, 144, 192, 216, 240, 264 hours. We compared the plasma levels of P4, mass spectrometry laboratory Thomson of the University of Campinas (UNICAMP). No effect was observed treatment and animal (p> 0.05) however there was only time effect (p <0.05). In the third experiment, 20 multiparous cows and cyclic undergone a complete protocol for fixed-time artificial insemination (TAI). In D0 treatment, all animals received 2 mg intramuscular (IM) of estradiol benzoate (Cronibest ® - Biogenesis-Tobago, Argentina). Half of the group (n = 10) received an intravaginal P4 device, Cronipres ® 3 uses, and the other half (n = 10) received the Cronipres ® Mono Dose M-24. In D8 proceeded to implant removal and application of IM 150 mg of D-cloprostenol (Croniben ®, Biogenesis-Bagó, Argentina). On Day 9, all animals received 1 mg IM. of estradiol benzoate (Cronibest ® Biogenesis-Bagó, Argentina). Was performed by ultrasound scanning of the ovaries every 24 hours from time of insertion of the implant to the withdrawal D8. From induction, all cows had their ovaries scanned and mapped every 12 hours for 4 days. Blood samples were taken on days six, seven and eight protocol to compare the plasma concentrations of P4 before removing the device. The variables, early new wave of follicular growth, diameter of the preovulatory follicle (retrospectively), ovulation rate and time of ovulation. Ovulation data were analyzed by logistic regression using PROC LOGISTIC and follicular development data, using PROC MIXED (SAS, version 9.3). The ovulation rate was 80% for both groups (P> 0.05). There was a tendency to anticipate ovulation (P = 0:07), cows in group B. A cow\'s ovulation group B anticipated for about 36 h. There was no difference in estatístisca dominant follicle diameter at the time of TAI, on the emergence of a new wave and pre ovulatory follicle size (p> 0.05).

Com o aumento do consumo de energia elétrica no Brasil, em função de fatores como o aumento da renda per capita e o maior acesso da população aos sistemas de suprimento, justifica-se a procura por fontes alternativas de energia. Esta Dissertação aborda o consumo energético residencial e analisa o papel do aquecimento de água para banho, que representa uma sobrecarga para infraestrutura elétrica no Brasil. O trabalho apresenta uma visão crítica em relação à predominância da eletricidade nesse uso final da energia, já que mais de 80% das residências brasileiras aquecem água para banho com chuveiros elétricos. Propõe-se a utilização de gases combustíveis para o aquecimento de água em residências, identificando que, em vários países do mundo, esse é um uso energético relativamente trivial dos gases combustíveis. A mera comparação internacional peca, porém, em não identificar as particularidades do sistema energético nacional, dentro das quais insere-se a predominância da eletricidade no aquecimento de água. O trabalho descreve os aspectos históricos, sociais, tecnológicos e econômicos que sustentam essa situação e apresenta as dificuldades que inibem iniciativas de promoção da substituição da eletricidade por gases combustíveis nesse serviço energético. A discussão é apresentada por meio da metodologia \"SWOT\", que conduz a uma análise comparativa abrangente entre os chuveiros elétricos e os aquecedores a gás. A metodologia utilizada é sintetizada e sua aplicação enfatiza quatro aspectos principais: tecnológicos, regulatórios, culturais e econômicos. A partir dos resultados apresentados, a Dissertação recomenda ações específicas para cada uma das quatro dimensões analisadas, que permitam ampliar a utilização do uso de gases combustíveis para aquecimento de água nas residências brasileiras, diversificando, portanto, a matriz energética desse segmento e reduzindo a participação relativa da eletricidade. O trabalho encerra com sugestões de temas cuja pesquisa merece ser aprofundada, bem como indicando que várias das críticas aqui apresentadas também são relevantes para a discussão do papel da energia solar térmica em ambientes residenciais no Brasil. / With the increase in electricity consumption in Brazil, due to factors such as increased per capita income and greater access of the population to supply systems, is justified the search for alternative energy sources. This dissertation adresses the residential energy consumption and examines the role of heating water for bathing, which is a burden on electrical infrastructure in Brazil. The paper presents a critical view of the predominance of electricity in final energy use, since more than 80% of Brazilian homes heat water to bath with electric shower. It is proposed the use of combustible gases for heating water in homes, identifying that in many countries, this is a relatively trivial energy use of mere international comparison sins, but not to identify the particularities of national energy system, within which is part of the dominance of electricity in water heating. The work describes the historical, social, technological and economic aspects that sustain this situation and shows the difficulties that inhibit initiatives to promote the substitution of electricity for combustible gases that energy service. The discussion is presented through the SWOT methodology, leading to a comprehensive comparative analysis of the electric showers and gas heaters. The SWOT methodology is synthesized and its application emphasizes four main aspects: technological, regulatory, cultural and economic. From the results presented, the dissertation recommends specific actions for each of the four dimensions analyzed, which can widen the use of the use of domestic gas for water heating in the Brazilian households, diversifying therefore the energy matrix of this segment and reducing the share on electricity. The work concludes with suggestions for topics whose research deserves to be thorough as well as indicating that several of the criticisms presented here are also relevant to the discussion of the role of solar energy in residential environments in Brazil.

A partir da compreensão de que, no contexto deste Fórum, as redes de migrantes adotam uma postura contrária à globalização hegemônica e apresentam a pauta da cidadania universal, estruturamos o referencial teórico em três partes, que abordam, respectivamente, a construção da pauta da cidadania universal, as reconfigurações da ideia de território a partir da globalização e as possibilidades abertas a partir das tecnologias e da internet e ainda as migrações como movimento social. Para a investigação empírica sobre os usos da internet, o percurso metodológico é construído a partir da observação de sites que compõem o campo de estudo, pesquisa documental e entrevistas em profundidade com integrantes de redes que participam da proposição do FSMM. A análise busca reconstruir e compreender os usos da internet por estes atores e aponta para dois principais eixos: ao mesmo tempo em que se constitui como o espaço para a articulação das diferentes redes que fazem parte do Fórum, a internet é também um espaço de emissão para dar visibilidade à agenda dos migrantes e difundir discursos contra-hegemônicos. / This research aims to understand the social uses of internet in the proposition of the World Social Forum on Migrations (WSFM), in order to understand the role information and communication technologies play to build a common agenda among social actors related to different territorialities. From the understanding that migrant networks of the Forum are against hegemonic globalization and propose the agenda of universal citizenship, we structure the theoretic discussion in three parts, which comprehends: 1) the construction of the global citizenship agenda, 2) other kinds of comprehension about the idea of territory in global societies and the new possibilities of technologies and internet, and 3) the migrations as a social movement. Methods for empirical investigation are built from the observation of websites, documental research and semi-structured interviews with migrants that take part on the organization of WSFM. The analysis tries to understand the uses of the internet made by these actors. Two categories emerge: at the same time internet becomes a space for the articulation of different networks, it is also conceived as a place for emission, in order to allow the visibility of the migrants agenda and diffuse counterhegemonic discourses.

Promovidas pelo governo estadual, foram impulsionadas pela aproximação das datas comemorativas do Sesquicentenário da Imigração Alemã e do Centenário da Imigração Italiana. O objetivo inicial destas comemorações era homenagear os grupos imigrantes que contribuíram para a formação étnica do estado. Mas, ao longo do processo comemorativo, as homenagens foram estendidas aos grupos negros e indígenas, convertendo o discurso comemorativo. Sendo assim, o principal objetivo desta pesquisa é explicitar como o governo do Rio Grande do Sul fez uso do passado imigrante do estado ao longo das comemorações do Biênio da Colonização e Imigração. Para tanto, a análise do processo comemorativo foi construída em três momentos: 1) A organização das comemorações. Analisamos o Decreto de instituição dos festejos, responsável por deliberar as ações a serem tomadas ao longo do processo comemorativo, e também a cerimônia solene de instalação das comemorações mediante a presença de autoridades no Palácio do Governo do Estado. Investigamos também a formação das Comissões de Homenagem, compostas por sujeitos autorizados pelo governo, e que ficaram responsáveis pela criação dos Programas Comemorativos de seus respectivos grupos de origem. E, sentimos a necessidade de mapear as cidades participantes dos festejos e quantificar/qualificar os atos celebrativos promovidos, mediante o desmembramento da Programação Oficial. 2) As comemorações ao Pioneirismo Luso-Brasileiro, ao Sesquicentenário Alemão e ao Centenário Italiano. Através da análise da réplica da chegada dos imigrantes alemães e italianos tendo como espectador o Presidente Ernesto Geisel, da promoção de eventos e da criação de instituições de fomento aos estudos do passado imigrante do estado e da construção de monumentos, confirmamos a ênfase dada às comemorações destes três grupos. 3) Por fim, os atos celebrativos promovidos em homenagem aos demais grupos de imigrantes, negros e índios. Analisamos o processo de ampliação de grupos a serem homenageados, e a consequente mudança no discurso oficial destas comemorações. / This dissertation has as its main subject of investigation the official commemorations of the Biennium of the Colonization and Immigration that took place in Rio Grande do Sul in 1974 and 1975. Promoted by the State government, these commemorations were motivated by the upcoming 150th anniversary of the German Immigration and the 100th anniversary of the Italian Immigration. The initial goal of these celebrations was to honor the different immigrant groups who contributed to the ethnic composition of the State. However, during the commemorative process, the tributes were extended to include homage to native and Afro-descendent Brazilians, thus, changing the initial official discourse. Therefore, the main goal of this research is to make explicit how the government of Rio Grande do Sul used the immigrant past of the State during the commemorations of the Biennium of the Colonization and Immigration. To this end, the analysis of the commemorative process is constructed in three periods: 1) The organization of the celebrations. We analyzed the decree instituting the festivities, which determined actions to be taken during the commemorative process and the official ceremony opening the celebrations in the presence of the State government authorities. We also investigated the formation of the Tribute Commissions, composed by individuals authorized by the government, who were also responsible for the creation of the Commemorative Programs of their respective ethnic groups. Also, we mapped the municipalities participating in the festivities, and quantified and qualified the celebratory acts promoted in face of the dismembering of the Official Program. 2) The commemorations honoring the Luso-Brazilian pioneering, the 150th anniversary of German immigration, and the 100th anniversary of Italian immigration. By analyzing the reenactment of the arrival of German and Italian immigrants having as spectator President Ernesto Geisel, the promotion of events and creation of institutions incentivizing the studies of the immigrant history in the State, and the building of monuments, we confirmed the emphasis given to the celebration of these three groups. 3) The celebratory acts promoted in honor of native and Afro-descendent Brazilians. We analyzed the process extending the tributes to these ethnic groups, and its resulting change in the official discourse of these commemorations.
