[pt] Esta tese tem por finalidade compreender o sentido do Pacto Nacional pela Alfabetização na Idade Certa (PNAIC) para o desenvolvimento profissional dos professores alfabetizadores em dois municípios de Minas Gerais de pequeno e grande porte: Matias Barbosa e Juiz de Fora. Ademais, procuramos entender que ações gestoras foram realizadas para que o PNAIC fosse implementado e chegasse até aos professores e às salas de aula de contextos tão diferentes. Nesse sentido, investigamos o PNAIC a partir das vozes não silenciadas dos professores alfabetizadores, procurando identificar as suas concepções e ações, no que tange à alfabetização, à formação continuada e à própria docência. O procedimento adotado foi a pesquisa qualitativa. Os instrumentos utilizados para a obtenção dos dados foram a aplicação de questionários com perguntas fechadas e abertas, assim como a realização de entrevistas semiestruturadas com diferentes atores (coordenadores locais, orientadores de ensino, professores-alfabetizadores, secretárias de educação e professores-formadores) que participaram do PNAIC em Matias Barbosa e Juiz de Fora, no período de 2013 a 2015. Além disso, recorremos aos documentos oficiais orientadores do PNAIC como fonte de dados sobre o desenho estrutural desse programa de formação. A análise dos dados da pesquisa mantém diálogo com pesquisadores dos campos da alfabetização (Mortatti, Carvalho, Soares); da formação e do desenvolvimento profissional (Tardif, Nóvoa, Gatti, André, Formosinho, García, Day). Os professores-alfabetizadores entrevistados apontam que a experiência com o PNAIC possibilitou o desenvolvimento profissional pelos fatores: troca de experiência, material rico para estudo e pesquisa, presença de atividades práticas e inovadoras. Pudemos constatar, através dos relatos, que a mudança da prática docente não afetou todos os professores que participaram da formação e que existem diferenças nos encaminhamentos das ações gestoras locais para que o PNAIC chegasse até ao professor e nas salas de aula. A diferença entre o processo de implantação do PNAIC nos dois municípios investigados foi percebida, principalmente, em relação à forma de adesão dos professores-alfabetizadores e orientadores de estudos e ao acompanhamento feito pelos orientadores de estudo e coordenadores pedagógicos das práticas alfabetizadoras no contexto escolar. Além disso, os professores apontam a relevância do acompanhamento das suas ações docentes, para o seu desenvolvimento profissional, pois permite a troca de experiência, o trabalho coletivo na busca da melhoria da prática docente e de soluções dos problemas da aprendizagem dos alunos. Através da pesquisa, ressaltamos a importância de programas de formação continuada construída na e com a escola, como o PNAIC, para a promoção do desenvolvimento profissional dos professores alfabetizadores. Conclui-se que o desenvolvimento profissional docente pode ser compreendido a partir da valorização profissional, da capacidade de aquisição e de veiculação de novos saberes e das competências para a prática alfabetizadora. Além disso, pode contribuir para o incentivo à inovação da prática, ao aperfeiçoamento, à troca de experiências, com vistas à melhoria do ensino e da escola em sua totalidade com reflexos na aprendizagem dos alunos. / [en] This thesis aims to understand the PNAIC, a program directed to the professional development of the literacy teachers and to the students’ education. To do so, there were analyzed two cities from Minas Gerais, a state in Brazil. Those are: Matias Barbosa e Juiz de Fora. Besides, this research tries to understand which management actions were made to implement PNAIC. So, the program was investigated through the non-silenced voices of the literacy teachers. This methodology was chosen, so that it could be possible to identify their conceptions and actions related to literacy, continuous formation and teaching itself. The adopted procedure was the qualitative research. The used instruments to collect data were: inquiries application with open and closed questions and semi structured interview with different actors, such as local coordinators; teaching advisors; literacy teachers; educational secretaries; and formation professors. All of them participated of PNAIC in Matias Barbosa and Juiz de Fora from 2013 to 2015. Besides, there were studied the official documents of the program and other sources of data. The data analysis was then crossed with researches from the field of literacy (Mortatti, Carvalo, Soares); and professional formation and development (Tardif, Nóvoa, Gatti, André, Formosinho, García, Day). The interviewed literacy teachers point out that the experience with PNAIC allowed the professional development. Through it, it was possible to exchange experience; have access to rich material for study and research; and to understand new activities and innovational practices. Those experiences show that teachers could change their teaching practice. Besides, the research also showed that there are differences on the local management practices related with PNAIC. Those dissimilarities of the program s implementation process on the two investigated cities were noticed mainly on the adhesion and follow up of the literacy professors and study advisors. Besides, the professors point out the relevancy of the follow up process to their teaching practices and professional development. Through it, is possible to improve educational methods, especially when finding new practices and solutions to the educational problems. The research shows the importance of continuous formation programs, as PNAIC, to the promotion of the professional development of literacy teachers. It is possible to conclude that the teaching professional development happen through the professional valuing and through the skills of acquiring new knowledges and competences to the literacy practice. Those kinds of programs also help to develop innovative practices, the experience exchange and its improvement. Besides, they also help to improve the educational practice as a whole. / [fr] Cette thèse a comme objectif comprendre le sens du Pacte National pour l Alphabétisation à l Âge Idéal (PNAIC, en portugais) pour le développement professionnel du professeur alphabétiseur et pour l enseignement des élèves dans deux municipalités de Minas Gerais, une petite et l autre grande: Matias Barbosa et Juiz de Fora. De plus, on cherche comprendre que des actions de gestion ont été réalisées pour que le PNAIC ait été mis en oeuvre et afin qu il soit arrivé jusqu aux professeures et aux salles de classe, qui existent dans des différents contextes. De cette manière, on vérifie le PNAIC à partir des voix expressives des professeurs alphabétiseurs, en cherchant identifier ses conceptions et ses actions en ce qui concerne l’alphabétisation, la formation continue et le propre enseignement. La procédure utilisée a été celle de la recherche qualitative. Les instruments employés, pour l acquisition des données, ont été l application de questionnaires avec des questions fermées et ouvertes, ainsi que la réalisation d interviews semi-structurés avec plusieurs subjects (coordinateurs locaux, conseillers pédagogiques, professeurs-alphabétiseurs, secrétaires d’éducation et professeurs-formateurs) qui ont participé du PNAIC à Juiz de Fora et à Matias Barbosa, pendant la période entre 2013 et 2015. En outre, nous avons recours aux documents d’orientation officiels du PNAIC comme source de données à propos de la conception structurale de ce programme de formation. L analyse des données de la recherche dialoguent avec les chercheurs du domaine de l’alphabétisation (Mortatti, Carvalho, Soares) et de la formation et du développement professionnel (Tardif, Nóvoa, Gatti, André, Formosinho, García, Day). Les professeurs alphabétiseurs interrogés indiquent que l’expérience avec le PNAIC a possibilité une évolution à cause des éléments suivants: échange de pratiques, riche matériel pour l’étude et la recherche, ainsi que la présence d activités pratiques et innovatrices. On a pu constater, parmi des rapports, que le changement de la pratique d’enseignement n’a pas affecté tous les professeurs qui ont participé de la formation et, aussi, qu il y a des différences, dans les manières employés par les actions de gestion locales, pour que le PNAIC soit arrivé jusqu’au professeur et aux salles de classe. La différence entre le processus d’implantation do PNAIC des deux municipalités recherchées a été aperçue, principalement, vis-à-vis la manière d adhésion des professeurs-alphabétiseurs et des conseillers d’orientation des études, et aussi par rapport à l accompagnement des pratiques d alphabétisation dans le cadre scolaire, réalisé par les conseillers d orientation et les coordinateurs pédagogiques. Par ailleurs, les professeurs indiquent la pertinence de l accompagnement de leurs enseignements pour leurs évolutions professionnelles, puisque cela permet l échange de pratiques et le travail collectif en quête de l amélioration de l enseignement et d’un dénouement des problèmes d apprentissage des élèves. Parmis l étude, nous soulignons l importance des programmes de formation continue construite à (et avec) l école, comme le PNAIC, pour l encouragement de l évolution professionnelle des professeurs alphabétiseurs. On y conclut que le développement professionnel d enseignement peut être compris à partir de la valorisation professionnelle, de la capacité d obtention et de propagation des nouveaux savoirs et des compétences pour la pratique d alphabétisation. En plus de cela, il peut contribuer pour l encouragement de l innovation de la pratique, au perfectionnement, à l échange d’expériences, à des fins d améliorer l enseignement et l école dans son intégralité, réfléchissant sur l apprentissage des élèves.

Winsor McCay drew delightful drawings about the dreams of a Welsh rarebit fiend, 'rare bits' inspired by an overindulgence in cheese. Dreams of the Rarebit Fiend was a Saturday cartoon that appeared in the New York Evening Telegram from 1904 to 1911, psychic twin to Little Nemo in Slumberland that appeared concurrently in the Sunday Funnies of the New York Herald from 1905-1911. 'Slumberland' was a Neo-classical fantasy that closely resembled the idealized White City of the Chicago World's Fair (1893), that inspired the architecture of Coney Island's Dreamland (1905-1911), which beckoned to McCay as he drew from his house just across Sheepshead Bay in Brooklyn. The capricious side of this Architecture emerged in McCay's cartoons. A self-taught illustrator, McCay began his career in Detroit working in dime museums, worlds of wonder—filled with monsters—dioramas and sideshow performers whose livelihood depended on their ability to amaze an audience. Just this sort of rare and gifted fellow, McCay parlayed his entertaining lampoonery of Slumberland into some of the world's first animations on vaudeville. As with the Rarebit Fiend, Little Nemo's dreams were brought on by overindulgence, in his case of too many donuts or Huckleberry Pie. But, this was merely a pretense for McCay's fantastical 'dream' mode of thinking, a potentially useful body of knowledge that was simultaneously explored by Sigmund Freud, Henri Bergson and Marcel Proust, who linked the mechanisms employed by the unconscious in dreaming to those at play in wit. Architectural drawing—seen through McCay's cartoons and early animations—has a kind of 'gastronomical' alchemy that inadvertently became a treatise on the architectural imagination. Fiend and Little Nemo affected the psychic mood of early modern Architecture—its 'childhood' in the milieu of White Cities—that was both added to and commented on by Winsor McCay's pen. His cartoons portray the hidden 'flavors' of the buildings springing up a century ago. This 'other'—surreal—aspect of the White Cities, seasoned with whirling iron Ferris wheels and Flip-Flop rides, newly invented elevators and electric lights—and even fun house mirrors that made buildings suddenly seem very tall—were the ingredients that caused the fiend and Nemo to wake up, which ultimately became the culinary school of modern Architecture. McCay's 'fiendish' depictions show us that the right blend of humor and awe is a recipe for happiness. / Doctor of Philosophy / Winsor McCay made cartoons of the 'nightmares' of a Rarebit Fiend with a witty, unflinching eye for detail. Those illustrations became a psychic twin to the architectural fantasies of a little boy in the 'funnies' section of the New York newspapers from 1905-1911. Dreams of the Rarebit Fiend and Little Nemo in Slumberland continue to entertain and edify us, while inadvertently acting as a guide to how the imagination works. McCay's celebrity as a cartoonist also led him to become one of the world's first animators, amazing vaudeville audiences with depictions of Little Nemo that were suddenly larger than life, illuminated, and mobile. Dreams were rediscovered in the early twentieth century as useful bodies of knowledge for understanding the self, seen through the writings of Sigmund Freud, Henri Bergson and Marcel Proust, who linked the mechanisms employed by the unconscious 'dreamer' to those at play in wit. That thinking was surrounded by the atmosphere in McCay's comedic sequential images, which in turn inspired the iconic dreamlike silent movies of Buster Keaton. A look at the birth of these art forms a hundred years ago provides insight into the psychic mood of early modern Architecture, but also to the imagining of today's world (both material and virtual) using the digital tools that are just being invented. Although McCay's cartoons are fiendish, they sustain the balance between dreaming and humor that is essential to imagining a happy modern life.

[pt] Mística Marial como caminho de fé é uma proposta para a formação de discípulos missionários de uma Igreja em saída, inspirada na experiência de fé vivida por Maria. Qual Maria? A Maria dos Evangelhos. Maria, pelo seu sim ao projeto de Deus de ser a mãe de Jesus, a Theotókos, viveu uma experiência do mistério de Deus no cotidiano de sua vida. A partir dessa experiência, sai apressadamente para acompanhar e atender a vida carente de cuidados. Maria sinaliza uma caminhada na fé com um dinamismo evangelizador. O presente trabalho propõe um diálogo entre duas épocas: a do Beato Chaminade (1761-1850) e a atual do Papa Francisco. O Beato Chaminade viveu num tempo de grandes transformações e desafios para a sociedade e para a Igreja. Ele vivenciou uma experiência do mistério de Deus em Cristo, inspirada por Maria, experiência essa que se deu durante o exílio em Zaragoza aos pés da Virgem do Pilar. A partir de então ele inicia seu novo apostolado, tendo em Maria um modelo de fé. Já o Papa Francisco, enfrenta grandes desafios, atendendo a um forte apelo para uma reforma da Igreja, uma conversão pessoal e pastoral: o sonho de uma Igreja pobre para os pobres, uma mãe de coração aberto. Maria, a Nossa Senhora da Prontidão, está sempre atenta e em atitude de escuta para com todos, especialmente os pobres. Para o Papa Francisco, existe uma íntima relação entre Maria, a Igreja e o povo fiel. Para ele, a devoção e a piedade popular constituem um lugar teológico e devem estar presentes na Nova Evangelização. A mistagogia marial, Maria, o ícone perfeito da fé e a primeira discípula missionária, sinaliza, por sua experiência mística, uma formação na verdadeira fé para o seguimento de seu Filho Jesus Cristo. Nesse processo de formação, que é humano e espiritual, temos uma mãe que acompanha, educa e cuida. Ela inspira um dinamismo de saída, de encontro, solidariedade e compaixão para com todos; um retorno às relações fundamentais com Deus, com o ser humano e com a casa comum, pois tudo está interligado, interrelacionado. / [en] Marial Mystic as a path of faith proposes the formation of missionary disciples of an outgoing Church, inspired by the experience of faith lived by Mary. Which Mary? The Mary of the Gospels. Mary, through her yes to God s project of being the mother of Jesus, the Theotókos, lived an experience of the mystery of God in her daily life. From this experience, she hurriedly leaves to follow and attend to life in need of care. Mary signals a journey in faith with an evangelizing dynamism. This work proposes a dialogue between two eras: that of Blessed Chaminade (1761-1850) and the current era of Pope Francis. Blessed Chaminade lived in a time of great transformations and challenges for society and the Church. He experienced the mystery of God in Christ, inspired by Mary. This experience took place during his exile in Zaragoza at the feet of the Virgin of Pilar. From then on, he began his new apostolate, having Mary as a model of faith. Pope Francis, in today s times, faces great challenges, responding to a strong call for a reform of the Church, a personal and pastoral conversion: the dream of a poor Church for the poor, a mother with an open heart. Mary, Our Lady of Readiness, is always attentive and listens to everyone in need, especially the poor. For Pope Francis, there is an intimate relationship between Mary, the Church and the faithful people. For him, devotion and popular piety constitute a theological place and must be present in the New Evangelization. Marial mystagogy, Mary, the perfect icon of faith and the first missionary disciple, signals (through her mystical experience) a formation in true faith to follow her Son Jesus Christ. In this process, which is human and spiritual, we have a mother who accompanies, educates and cares. Sheinspires an outgoing dynamism, encounter, solidarity and compassion towards everyone; a return to fundamental relationships with God, with human beings and with the common home, as everything is interconnected, interrelated.

Submitted in fulfillment of the requirements for the degree of Master of Engineering in Chemical Engineering, Durban University of Technology. Durban. South Africa, 2015. / Several areas in the world such as the United States of America, Sri Lanka, China, Argentina, Canada, Tanzania, Kenya, South Africa and many others have a problem of high fluoride content in drinking water. Generally fluoride levels above 1.5 ppm in water may result in dental and skeletal fluorosis in humans depending on quantity consumed (Fan et al., 2003; Meenakshi, 2004). Remote rural areas where there are no water treatment facilities are more vulnerable to this problem. Adsorbents such as activated alumina and FR-10 resin seem to have a potential for successful application in rural areas. These methods however require pre-treatment if the feed has high turbidity. A membrane based system called woven fabric microfiltration gravity filter (WFMFGF) developed by Durban University of Technology proved to be suitable for turbidity removal. The main objective of this research was to develop a small water treatment system for fluoride removal. The small water treatment system developed in this study consists of WFMFGF for pre-treatment and an adsorption column. The WFMFGF is made up of a 40 L container packed with 15 immersed flat sheet membrane elements. The operation of the WFMFGF is in batch mode, driven by varying static head. The static head variation results in flow rate variation through the system. This in turn result in variation of contact time, velocity as well as pressure drop in the fluoride removal unit. Specific objectives of the study were: (1) to establish the maximum and minimum flow rates through the WFMFGF system, the total run time before cleaning is required and the best cleaning method for this particular membrane system. (2) to evaluate and compare the performance of activated alumina and FR-10 resin on varying contact time, velocity and pressure drop on the fluoride removal unit. The adsorbents were also compared on adsorption capacity, cost and ease of operation. The minimum and maximum flow rates through the WFMFGF were found to be 5 l/hr and 100 l/hr respectively. It was found that the system can be run for more than a month before requiring cleaning. The suitable cleaning method was found to be soaking the membranes in 0.0225 percent sodium hypochlorite solution overnight and brushing them using a plastic brush. The comparison of the performance of FR-10 resin to activated alumina found that the adsorbents gave equal performance based on the given criteria. FR-10 resin had higher adsorption capacity, gave good quality treated water even with shorter contact time and operated at wider velocity range. Activated alumina on the other hand had an advantage of lower costs, lower pressure drop and ease of use. According to Pontius (1990), the performance of activated alumina can be improved by intermittent operation. Point of use (POU) systems are generally operated intermittently. This improves the fluoride removal efficiency of activated alumina giving it more advantage over FR-10 resin. Based on this activated alumina was selected as the best adsorbent for the system. After the adsorbent was selected, the adsorption column was designed. The column operation regime was 3.5 minutes minimum contact time and 1.17 to 7.8 m/hr velocity range. The activated alumina adsorption capacity was 1.53mg/g. The column had an inside diameter of 70 mm. It was packed with activated alumina to a bed height of 400 mm. The column inlet and outlet pipes were made of PVC with a standard pipe size of 20 mm outside diameter. A valve at the column inlet pipe allowed water to flow through the system.

<p>Problem – The expansion of global trade and supply chain integration has put great emphasison logistics, particularly in the intermediary sector, freight forwarders. Whilst in developedcountries freight forwarders benefit from competitive markets and trade facilitatingpolicies, this sector in West coast Africa exhibits low logistics performance levels. Inorder to address such issues, one needs to analyse the problem and identify the causes; thisthesis focuses on identifying the bottlenecks in the freight-forwarding sector in west coastAfrica.Purpose – The main purpose of this study is to identify the bottleneck/s within thefreight-forwarding industry in west coast Africa, namely: Angola, Cameroon, DR of Congo,Gabon, and Nigeria.Method – This thesis employs a pre-study and case study method, to ensure sufficient collectionof relevant material, taking into account the lack of research in this subject. We usedthe material obtained from the interviews and the secondary source, to structure our purpose,research questions, and to define the case of our study.Results – The study concludes with a series of interesting findings; First, the activity of aFreight Forwarder depends on a series of factors that do not depend on the Freight Forwarderper se. And second, Freight Forwarders in order to accomplish their tasks, have accessto services that are shared by all providers, and that are beyond their control. To conclude,the study identifies infrastructure as a major bottleneck in the Freight Forwarding sector.</p>

Cette thèse porte sur l'analyse mathématique de modèles de réaction-dispersion de la forme [delta]tu=D(u) +f(x,u). L'objectif est de comprendre l'influence du terme de réaction f, de l'opérateur de dispersion D, et de la donnée initiale u0 sur la propagation des solutions de ces équations. Nous nous sommes intéressés principalement à deux types d'équations de réaction-dispersion : les équations de réaction-diffusion où l'opérateur de dispersion différentielle est D=[delta]2z et les équations intégro-différentielles pour lesquelles D est un opérateur de convolution, D(u)=J* u-u. Dans le cadre des équations de réaction-diffusion en milieu homogène, nous proposons une nouvelle approche plus intuitive concernant les notions de fronts progressifs tirés et poussés. Cette nouvelle caractérisation nous a permis de mieux comprendre d'une part les mécanismes de propagation des fronts et d'autre part l'influence de l'effet Allee, correspondant à une diminution de la fertilité à faible densité, lors d'une colonisation. Ces résultats ont des conséquences importantes en génétique des populations. Dans le cadre des équations de réaction-diffusion en milieu hétérogène, nous avons montré sur un exemple précis comment la fragmentation du milieu modifie la vitesse de propagation des solutions. Enfin, dans le cadre des équations intégro-différentielles, nous avons montré que la nature sur- ou sous-exponentielle du noyau de dispersion J modifie totalement la vitesse de propagation. / This thesis deals with the mathematical analysis of reaction-dispersion models of the form [delta]tu=D(u) +f(x,u). We investigate the influence of the reaction term f, the dispersal operator D and the initial datum u0 on the propagation of the solutions of these reaction-dispersion equations. We mainly focus on two types of equations: reaction-diffusion equations (D=[delta]2z and integro-differential equations (D is a convolution operator, D(u)=J* u-u). We first investigate the homogeneous reaction-diffusion equations. We provide a new and intuitive explanation of the notions of pushed and pulled traveling waves. This approach allows us to understand the inside dynamics the traveling fronts and the impact of the Allee effect, that is a low fertility at low density, during a colonisation. Our results also have important consequences in population genetics. In the more general and realistic framework of heterogeneous reaction-diffusion equations, we exhibit examples where the fragmentation of the media modifies the spreading speed of the solution. Finally, we investigate integro-differential equations and prove that emph{fat-tailed} dispersal kernels J, that is kernels which decay slower than any exponentially decaying function at infinity, lead to acceleration of the level sets of the solution u.

[pt] A tese Viagens modernistas: Europa e Brasil sob a ótica de António de Alcântara Machado, Blaise Cendrars e Oswald de Andrade parte da leitura comparada de três obras literárias publicadas durante a década de 1920, Pathé-Baby (1926), de António de Alcântara Machado; Pau Brasil (1925), de Oswald de Andrade; e Feuilles de route (primeiramente dividida em três partes editadas entre 1924 e 1928, Le Formose, São Paulo e Inédites, e reunidas pelo autor em 1944), de Blaise Cendrars (escritor suíço de expressão francófona). Tendo por premissa três eixos temáticos que aproximam tais obras – a saber, as vanguardas históricas, a viagem e o olhar do autor-viajante –, a tese aponta como a literatura de viagem e o olhar sobre o outro se modificaram com o advento das vanguardas e se estrutura, assim, a partir de três questões principais suscitadas pela leitura do corpus literário. Primeiramente, investiga em que medida os referidos textos contribuem para a solidificação do projeto modernista brasileiro, ao trazer para a cena de vanguarda, eminentemente urbana, a poesia e a crônica de viagem. Em seguida, elucida as maneiras pelas quais se trava o diálogo entre a modernidade europeia presenciada por Alcântara Machado – e trazida a nós também por Blaise Cendrars – e o passado colonial brasileiro que Oswald desvela em seu ritual antropofágico de construção da vanguarda artística brasileira. Por fim, analisa em que medida se pode considerar Pau Brasil e Feuilles de route obras espelhadas, simétricas, em que a paisagem e a história do Brasil guiam o olhar e a pena de ambos os poetas, permitindo lê-las como obras contínuas, como uma espécie de guia poético de uma viagem que, zarpando da Europa, adentra o Brasil e a ela retorna. Além disso, uma vez que tal leitura é feita à luz tanto de teorias sobre literatura de viagem como dos estudos culturais, também se discutem outros aspectos como discursos de identidade e alteridade, cosmopolitismo, experiência urbana, e intermidialidade. / [en] Modernist Journeys: Europe and Brazil from the Perspective of António de Alcântara Machado, Blaise Cendrars and Oswald de Andrade is a thesis that starts from the comparative reading of three literary works published during the 1920s, Pathé-Baby (1926) by António de Alcântara Machado; Pau Brasil (1925), by Oswald de Andrade; and Feuilles de route (first divided in three parts, edited between 1924 and 1928, Le Formose,São Paulo and Inédites, and later collected by the author in 1944), by Blaise Cendrars (Swiss writer of French-speaking expression). Having as its premise three thematic axes that approximate such works – namely, the historical vanguards, the journey and the traveling author s point of view –, the thesis points out how the travel literature and the look on the other have changed with the advent of the vanguards and is thus structured on the basis of three main questions raised by the reading of the literary corpus. Firstly, it investigates to what extent these texts contribute to the solidification of the Brazilian modernist project, by bringing poetry and travel chronicles to the vanguard scene, eminently urban. It then elucidates the ways in which the dialogue between the European modernity witnessed by Alcântara Machado – and brought to us by Blaise Cendrars – and the Brazilian colonial past that Oswald reveals in his anthropophagic ritual of building the Brazilian artistic vanguard, is elucidated. Finally, it analyzes the extent to which one can consider Pau Brasil and Feuilles de route mirrored, symmetrical works, in which the landscape and the history of Brazil guide the eyes and the pen of both poets, allowing them to read them as continuous works, as a kind of poetic guide of a journey that, starting from Europe, enters Brazil and returns to it. Moreover, since such a reading is made in light of both theories on travel literature and cultural studies, other aspects such as discourses of identity and otherness, cosmopolitanism, urban experience, and intermediality are also discussed. / [fr] La thèse Voyages modernistes : l Europe et le Brésil dans la perspective de António de Alcântara Machado, Blaise Cendrars et Oswald de Andrade part de la lecture comparative de trois oeuvres littéraires publiées au cours des années 1920, Pathé-Baby (1926), de António de Alcântara Machado ; Pau Brasil (1925), de Oswald de Andrade ; et de Feuilles de route (au début divisée en trois parties éditées entre 1924 et 1928, Le Formose, São Paulo et Inédites, et réunies par l auteur en 1944), de Blaise Cendrars. À partir de trois thèmes principaux qui amènent ces oeuvres – à savoir, les avant-gardes historiques, le voyage et le regard de l auteur-voyageur –, la thèse démontre comment la littérature de voyage et le regard de l autre ont changé avec l arrivée des avant-gardes et se construit, ainsi, à partir de trois questions principales soulevées par la lecture du corpus littéraire. Tout d abord, cette thèse examine dans quelle mesure ces textes contribuent à la solidification du projet moderniste brésilien, en portant la poésie et la chronique de voyage à la scène de l avant-garde, éminemment urbaine. Ensuite, elle élucide les façons par lesquelles se donne le dialogue entre la modernité européenne témoignée par Machado – et aussi apportée à nous par Blaise Cendrars – et le passé colonial brésilien, lequel Oswald révèle dans son rituel cannibale de construction de l avant-garde artistique brésilienne. Enfin, elle analyse dans quelle mesure Pau Brasil et Feuilles de route peuvent être considérés des oeuvres en miroir, symétriques, où le paysage et l histoire du Brésil guident le regard et l écriture de ces poètes, ce qui permet de les lire comme des oeuvres continues, une sorte de guide poétique de voyage qui part de l Europe vers le Brésil et à elle retourne. En outre, une telle lecture étant faite à la lumière des deux théories sur la littérature de voyage et les études culturelles, d autres aspects tels que les discours d identité et d altérité, le cosmopolitisme, l expérience urbaine et l intermédialité sont également discutés.

Andelen vegetarianer och veganer i världen ökar successivt. En av många anledningar till detta är att man som mottagare påverkas av djurrättsliga publiceringar på sociala medier. Många organisationer som försöker stoppa djurplågeri och förespråka ett veganskt leverne väljer att, genom sin visuella kommunikation, inrama sina publiceringar negativt, vilket kan tas emot som stötande av mottagaren. Denna studies syfte är därför att undersöka hur mottagaren påverkas av stötande innehåll i form av fotografier på sociala medier, med en djurrättsorganisation som avsändare. Organisationen valdes ut i en initial förstudie, tillsammans med sex fotografier uppdelade i tre innehållstyper. Dessa olika innehållstyper låg till grund för en kvantitativ del i form av en enkät som besvarades av 49 informanter, för att få klarhet kring vilken som mottogs bäst - och varför. Därefter följde en kvalitativ del, där en fokusgrupp bestående av sex informanter fick tycka till och diskutera de tre kategorierna av bilder. Studiens resultat visar att de tre innehållstyperna är olika effektiva beroende på mottagaren. Mottagare som ofta utsätter sig för stötande innehåll blir mättade och kan lätt bli emotionellt distanserade. Likaså visar studien att en alltför enformig inramning från organisationens sida kan resultera i att innehållet blir synonymt med dem och att mottagaren kopplar de negativa känslor som väcks av bilderna direkt till organisationen.
