The fusarium wilt is the major disease that attacks the pipericultura in Brazil and is caused by the fungus Fusarium solani f. sp. piperis (Nectria haematococca f. sp. piperis). Plant growth and root diseases are directly influenced by physical, chemical and biological soil environment, which are interconnected and form complex associations between them. The plant nutrition and a fertile soil with good physical characteristics influence all parts of the triangle of root diseases. New tools to investigate the variability and complexity of the interaction between the soil environment and pathogen are poorly studied, so the aim of this study was to research and implement methods of geostatistics to understand the distribution and spatial correlation of the intensity of Fusarium in black pepper crop with soil attributes. The experiment was conducted in the period from 2010 to 2011 in the North of Espírito Santo, Brazil. Geostatistics was used to study the spatial dependence and implanted a regular sampling grid of 12,000 m2. For the intensity of the disease was performed seven assessments, totaling 303 days, making the last evaluation soil samples for determinations chemistry, physics and texture. For the spatial correlation between disease severity with soil attributes, we used the analysis of variograms. The maps of the distribution of the disease over time show an initial focus on the edges of the crop, alongside a crop of older black pepper kingdom. The disease correlates spatially with the attributes fine sand ratio Mg / K, magnesium, pH, exchangeable acidity and base saturation / A pimenta-do-reino é uma das especiarias mais importantes e consumidas no mundo. A fusariose é a principal doença que ataca a pipericultura no Brasil e é causada pelo fungo Fusarium solani f. sp. piperis (Nectria haematococca f. sp. piperis). O desenvolvimento das plantas assim como das doenças radiculares são influênciadas diretamente pelos componentes físicos, químicos e biológicos do ambiente do solo, que são interligados e formam associações complexas entre si. A nutrição da planta e um solo fértil com boas características físicas influênciam todas as partes do triângulo das doenças radiculares. Novas ferramentas capazes de pesquisar a variabilidade e a complexidade da interação entre ambiente do solo e patógeno são pouco estudadas, portanto, o objetivo do trabalho foi pesquisar e aplicar métodos da geoestatística para compreender a distribuição e a correlação espacial da intensidade de fusariose em pimenta-do-reino com os atributos do solo. O experimento foi conduzido no período de 2010 a 2011, na Região Norte do Estado do Espírito Santo. A geoestatística foi utilizada para estudar a dependência espacial e implantou-se uma malha amostral regular de 12.000 m2. Para a intensidade da doença foi realizada sete avaliações, totalizando 303 dias, realizando na ultima avaliação as amostragens de solo para determinações química, física e textural. Para a correlação espacial entre intensidade da doença com os atributos do solo, utilizou-se o escalonamento dos variogramas. Os mapas da distribuição da doença ao longo do tempo mostram foco inicial nas bordas da lavoura, ao lado de uma lavoura mais velha de pimenta-do-reino. A doença correlaciona-se espacialmente com os atributos areia fina, relação Mg/K, magnésio, pH, acidez trocável e saturação por base

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This is a study that has as its theme the traditional games, understood as cultural manifestations produced by humankind throughout history. We seek to investigate the traditional games in some societies in Rio Grande do Sul (RS) and the meanings attributed to them by social subjects who experienced the transformation of those spaces and times. Therefore, the research is characterized as a field and documental research, making use of in-depth interviews. We have covered two societies from São João do Polêsine, RS, i.e., the "Sociedade Agrícola Cultural Esportiva Polesinense" and the "Sociedade Agrícola Cultural Esportiva Vale Vêneto". These entities present themselves as living spaces for traditional games and have changed with the expansion of the capitalist system. We found that the transformations of space and time for traditional games modify their meanings, as these change those, in a dialectical relationship. To keep the meanings attributed to traditional games, the subjects resist against spatiotemporal transformations, with movement between conformity and resistance. The research aims to contribute to deepening the understanding of how the traditional game has been historically reconfigured. / Este é um estudo que tem como tema os jogos tradicionais, compreendidos como manifestações culturais produzidas pela humanidade ao longo da história. Buscamos investigar os jogos tradicionais em algumas Sociedades no Rio Grande do Sul (RS) e os sentidos atribuídos a eles por sujeitos sociais que vivenciaram o processo de transformação desses espaços e tempos. Para tanto, a pesquisa é caracterizada como de campo e documental, lançando mão de entrevistas em profundidade. Abarcamos duas Sociedades do município de São João do Polêsine, RS, ou seja, a Sociedade Agrícola Cultura Esportiva Polesinense e a Sociedade Agrícola Cultural Esportiva Vale Vêneto. Estas entidades apresentam-se como espaço de vivência dos jogos tradicionais e sofreram mudanças com a expansão do sistema capitalista. Identificamos que as transformações dos espaços e tempos para os jogos tradicionais modificam seus sentidos, assim como esses mudam aqueles, numa relação dialética. Para manterem os sentidos atribuídos aos jogos tradicionais, os sujeitos resistem às transformações espaciotemporais, com o movimento entre o conformismo e a resistência. A pesquisa visa contribuir para aprofundar o entendimento de como o jogo tradicional vem sendo reconfigurado historicamente.

Notre recherche, bien qu’ancrée dans les Sciences du Langage s’inscrit dans une démarche interdisciplinaire entre Linguistique et Philosophie articulant Analyse des Interactions et Phénoménologie. Il s’agit d’étudier l’identité en interaction en tant que phénomène intersubjectif, langagier et technique. L’existence corporelle, sensorielle, relationnelle, et sociale des humains se trouvant désormais engagée dans des dispositifs d’interactions numériques, des modalités inédites d’intersubjectivité se déploient notamment par écran. C’est pourquoi nous nous proposons d’analyser les nouvelles dimensions constitutives de l’intersubjectivité et mises en jeu dans les interactions numériques. Dans la première partie de notre thèse, notre parcours théorique, il s’agit de saisir la nature de la co-construction identitaire, les enjeux de la rencontre interindividuelle en tant que phénomène intersubjectif et les spécificités des interactions numériques aux cadres spatio-temporels complexes. Nous proposons, en premier lieu, de définir, par une approche phénoménologique, l’événement de la rencontre avant de nous intéresser aux propriétés phénoménotechniques de l’intersubjectivité numérique. En second lieu, dans ce parcours théorique, par une approche interactionniste, nous nous attardons sur la place du langage dans la co-construction des identités ; une place importante est accordée à la séquentialité interactionnelle par laquelle les sujets façonnent l’interaction ainsi qu’à la corporéité de l’action hors et par écran. Nous soumettons alors, dans la seconde partie de notre thèse, ces théorisations à l’analyse des données de notre corpus. Dans ce parcours empirique, sont analysées des rencontres par écran entre participants géographiquement distants. Cette analyse nous permet notamment de dresser une topographie des espaces-temps impliqués dans l’interaction physico-numérique, une typologie des actes de prise d’existence à l’écran et une description du processus ontologique identitaire en interaction. / Though our research is firmly anchored within the field of linguistics, it constitutes an interdisciplinary approach as well, aiming to establish a dialogue between Interaction Analysis and Phenomenology. This research examines the complex notion of identity by defining it as a verbal, technical, and intersubjective phenomenon. The bodily, sensory, relational and social human existence is henceforth engaged in digital interaction devices inducing unprecedented modalities of intersubjectivity. Therefore, we propose to analyze the novel features of intersubjectivity involved in digital interactions. In the first part of our dissertation, the theoretical exploration, we seek to apprehend the nature of identity co-construction, the stakes of interindividual encounter understood as an intersubjective phenomenon, and the spatio-temporal characteristics of digital interactions. Firstly, through a phenomenological approach, we define the encounter as a meaningful event and we explore the phenomenotechnical properties of digital intersubjectivity. Secondly, through an interactionist approach, we focus on language and its role in identity co-construction, and more specifically on sequence organization and embodiment within physical and digital interactions. Thereafter, in the second part of our dissertation, those theorizations are submitted to a data analysis. This empirical exploration consists in studying online encounters between geographically distant participants. This study allows us to draw a topography of the spatio-temporal framework of phygital interaction, a typology of the acts of enacting existence on screen and a description of the ontological process of identity co-construction.

Les questions de mobilité et de logement sont aujourd’hui au centre des enjeux du développement urbain. La hausse du taux de motorisation, de la pression sur le marché du logement, poussent à une déstructuration des liens de proximité et génèrent aujourd’hui une saturation du système de transport. De cette difficulté à se déplacer naissent des tensions (augmentation du temps de trajet, risque de retard, etc.). L’objectif de cette thèse est alors d’étudier le poids de ces tensions dans la décision de déménager. Une enquête a été réalisée auprès de 500 résidants actifs luxembourgeois ayant déménagé sans changer de lieu de travail. Les résultats montrent que certains individus se sont bien rapprochés de leur lieu de travail dans le but de réduire ces tensions. Cette recherche a donc permis de mettre en évidence des liens de conjonction entre la mobilité quotidienne et résidentielle et d’aboutir à une meilleure compréhension du système de la mobilité spatiale locale des individus. / Mobility and housing are today at the centre of the urban development issues. Indeed, the raise of the motorization rate, combined with the increasing property market pressure, are leading to a disruption of proximity links and tend to generate transportation system saturation. Those difficulties affecting mobility gives tensions (increased travel time, risk of delay, etc.). The objective of this thesis was to study the weight of those tensions in the residential mobility process. A survey was conducted among 500 active’s Luxemburg residents. Those people have recently changed housing without having changed their workplace. Results show that some people get now closer to their workplace in order to reduce their daily mobility tensions. This research helped highlighting links between daily mobility and residential mobility conjunction and lead to a better understanding of the local spatial mobility system of individuals.

Un des grand défis de la physique actuelle est la quantification de la gravit é. La théorie d’Einstein est remarquable pour ses prédictions. Malheureusement, elle reste une théorie classique et de ce fait en désaccord avec les progrès actuels en physique des particules qui montrent qu’à faible distance, une théorie physique doit être quantique. Une des pistes pour résoudre ce problème est d’étudier la version classique de la gravité dans l’espoir d’en déduire des propriétés ou même la forme de la théorie quantique.<p><p>Un des outils pour étudier une theorie est la notion de dualité. On dit que deux théories sont duales quand elles décrivent le même système par des moyens différents. La dualité est le dictionnaire permettant de passer d’une description à l’autre. Dans ma thèse, j’ai étudié deux dualités s’appliquant à la gravité en 4 dimensions.<p><p>La première est connue sous le nom de dualité électromagnétique. A l’origine, cette dualité s’applique à l’électromagnétisme où elle échange les rôles du champ & / Doctorat en Sciences / info:eu-repo/semantics/nonPublished

Autour d'une question fondamentale comme celle de la présence, nous mobilisons une littérature interdisciplinaire grâce à laquelle les contributions de l'anthropologie et de la géographie sociale, de la théorie du théâtre et du cinéma, des performance studies, de la psychanalyse et de la sociologie, sont articulées dans la perspective de la phénoménologie et des sciences de l'information et de la communication. Notre façon d'habiter le monde a changé : l'être-en-ligne se révèle alors comme étant la nouvelle condition existentielle. La connexion au réseau, le web, les applications, dans leur ensemble, disposent les choses et les personnes selon des relations opérationnelles de proximité spatio-temporelle. Notre espace est un espace performatif, car il se produit à partir de nos actions, nos postures et nos gestes, gestes photo-graphiques, éminemment réflexifs, qui créent la mise en scène numérique. En allant au-delà du modèle de « l'interface », cette mise en scène est devenue la spatialité de raccordement de tous nos espaces d'action. Nous identifions alors la performativité du direct et de l’enregistrement, la performativité de l’être en train de…, de l’attention présentielle et du « suspens gestuel », la performativité des algorithmes et des notifications, la performativité des emoji et de tout ce qui «fait visage»; et encore, la performativité des questions et des messages automatiques derrière lesquels parfois il y quelqu’un et d’autres fois il n’y a personne (comme lorsqu’on sonne à la porte dans une scène de La cantatrice chauve). A la lumière d'une analyse socio-sémiotique de la gestuelle numérique, des écrans, du graphisme propre aux réseaux sociaux et aux applications de messagerie instantanée tout comme des « protocoles de la vie quotidienne », nous décrivons la présence comme étant toujours l'effet d'une médiation. Cette médiation est, à la fois, disjonction et fiction, car elle se manifeste dans l'écart et dans la différence aussi bien que dans la fiction de l'hypermédiatété. Il y a de la présence, en somme, s'il y a du jeu, au sens spatiale de l'expression « il y a du jeu » mais aussi au sens fictionnel et ludique du jouer à.…. Comme le garçon du café décrit par Sartre, nous jouons, fictionnons et de-fictionnons le réel, en faisant « comme si » était vrai ce qui, par ailleurs, l'est vraiment. / Around the fundamental question of presence, I draw on interdisciplinary literature whose contributions from the fields of anthropology and social geography, theatre and cinema theory, performance studies, psychoanalysis and sociology are articulated from the perspective of phenomenology and information and communication sciences. Our way of inhabiting the world has changed: online-being is the new fundamental existential condition. Our space is a performative space, because it is produced through our actions, our gestures, eminently reflexive photographic gestures, which create our digital mise en scène. This space has become the space which links together all of our active and social spaces. Here, I single out live and recorded performativity, the performativity of do-ing, the performativity of algorithms and of questions, of emojis and of all that which “fait visage”. After a socio-semiotic analysis of digital gestures, screens, the graphics of social networks and presence protocols, I describe presence as always being a mediation effect. This mediation is at once disjunction and fiction, beacause it works as a difference and as the fiction of hypermediality. Presence exists where there is play (jeu) as in the french expression “il y a du jeu”, refering to space, and in its fictional sense of play-acting. As with Sartre's café waiter, we play act in order to create reality and consciousness through fiction.

Student Number : 7805464 - MA dissertation - School of SLLS - Faculty of Arts / This dissertation interrogates Anne Landsman’s The Devil’s Chimney. The novel is narrated by the poor-white alcoholic, Connie, who imagines a story about Beatrice, an English colonist living on a farm in the Little Karoo. Connie, who is a product of the apartheid era, interweaves her own story with that of Beatrice’s and, in this way, comes to terms with her own memories, her abusive husband and the new South Africa. Connie deploys the genre of magical realism to create a defamiliarised farm setting for Beatrice’s narrative. She thus challenges the stereotypes associated with the traditional plaasroman and its patriarchal codes. These codes are also subverted in Connie’s representation of Beatrice, who contests her identity as the authoritative Englishwoman, as constructed by colonial discourse. In addition, Beatrice’s black domestic, Nomsa, is given voice and agency: facilities denied to her counterparts in colonial and apartheid fiction. Nomsa’s relationship with Beatrice is also characterised by subversion as it blurs the boundaries between colonised and coloniser. In this regard, the text demands a postcolonial reading. Connie, in narrating Beatrice’s and Nomsa’s stories, reinvents their invisible lives and, by doing so, is able to rewrite herself. In this, she tentatively envisions a future for herself and also potentially ‘narrates’ the nation, thus contributing to the new national literature. The nation is inscribed in the Cango caves, whose spaces witness the seminal episodes in Beatrice’s narrative. In these events, the caves ‘write’ the female body and women’s sexuality and the text thus calls for an engagement with feminism. The caves also inscribe South African history, the Western literary canon, the imagination and Landsman’s own voice. Hence, the caves assume the characteristics of a palimpsest. This, together with the metafictive elements of the novel, invites an encounter with postmodernism.
