Esta investigación tiene como objeto de estudio al reality show Rupaul’s Drag Race, el cual es analizado a partir de la teoría de la performatividad de género de la filósofa estadounidense Judith Butler, donde la autora toma como ejemplo a la performance drag para mostrar que el género es se performa, es decir, que se construye y da la ilusión de ser una esencia a través de los actos performativos. Para Butler, las drag queens imitan y actúan el género para hacer su performance, por lo que evidencian esta performatividad. Mediante el análisis del discurso, analizaremos bajo una mirada cualitativa-deductiva siete capítulos del reality show para reconocer si se cumple o no la performatividad del género en ellos; además de identificar en qué segmento de la estructura narrativa del programa se muestran más y quiénes son los personajes dentro del reality que más se acercan a este concepto. Finalmente, como conclusión principal hallamos que la teoría de la performatividad se cumple, en su mayoría, en el reality show Rupaul’s Drag Race y que son las drag queens que se acercan más a este concepto a través de lo expresado verbalmente por ellas en la ejecución de los desafíos principales del programa y la presentación de sus personajes en la pasarela. Estos dos segmentos coinciden dentro de la estructura narrativa del programa, con el segundo acto de acuerdo al Paradigma de Syd Field, justo en donde se ubica la confrontación del relato y la toma de decisiones por parte de los personajes, siendo cada uno de ellos el primer y segundo nudo de la trama.

This thesis examines the flow around bluff bodies placed at the floodplain edge in a compound, open channel. The floodplain edge location is associated with a strong shear layer between lower velocity floodplain flow and high velocity flow in the main channel. The drag force exerted by a bluff body is dependant on the way in which the flow separates around the body and subsequently recovers but the drag coefficients typically used to represent the effects of bluff bodies are based on experiments on bodies in geometrically simple channels. The differences induced in the wake structures and therefore in the drag coefficients of bluff bodies when they are placed in the shear layer at the floodplain edge are little understood. In this study, experimental data is gathered that allows direct comparison of the wakes of identical bluff bodies, both emergent (surface-piercing) and submerged, in simple and compound open channels. For the compound channel scenarios, for both single and multiple block arrangements, turbulence data is also reported. These results are augmented using a computational model based on the solution of the 3D Reynolds Averaged Navier Stokes equations, using a non-linear turbulence model. The results show that the changes induced in the wake structures due to their location at the floodplain edge of the compound channel can have a significant effect on the drag coefficient. For the emergent bodies, the proximity of the deep main channel flow is shown to impact in a complex manner upon the processes of reattachment and re-separation, changing the formation of vorticity in the wake. For the submerged bodies, this is complicated by asymmetry in the same processes on the block top. For both body types, separation on the main channel side results in the creation of a strong axial circulation at the floodplain edge and the decay of the wake is asymmetrically affected by the differing behaviour of the turbulence on the two sides.

The first part of this thesis deals with the study of mesoscopic fluctuations of the Coulomb drag resistance in double-layer GaAs/AlGaAs heterostructures, both in weak magnetic fields and strong magnetic fields. In the second part, measurements are made in a monolayer graphene structure, specifically of the quantum lifetime, and the mesoscopic resistance fluctuations at quantising magnetic fields.

Ce travail a pour objectif d'améliorer la prédictivité des modèles à deux fluides pour la description des lits fluidisés gaz-solide pour les particules du groupe A dans la classification de Geldart. La première partie traite de l'incorporation de nouveaux phénomènes physiques dans le formalisme statistique utilisé : collisions induites par le cisaillement, phénomènes de lubrification lors des chocs et forces inter-particulaires. La deuxième partie traite de la résolution numérique du modèle. Il est montré que la simulation des lits de particules de type A présente une très forte sensibilité au maillage, conduisant à une surestimation de la hauteur du lit. L'introduction du formalisme filtré permet d'identifier la traînée filtrée comme étant l'origine principale du problème. Deux modèles de sous-maille sont proposés pour la prédiction de celle-ci et sont testés à la fois sur une configuration académique et sur une expérience de laboratoire. / This work aims to increase the predictivity of the two-fluid model in gas-solid fluidized beds of Geldart A particles. The first part deals with the integration of physical phenomena into the two-fluid model: shear-induced collisions, lubrication between particles and inter-particular forces. The second part deals with the practical resolution of the two-fluid model using numerical codes. It is shown that bed expansion for Geldart A particles have a strong dependance on the mesh size used to compute the flow, leading to a major overestimation. The filtered approach is used and points up the filtered drag as the key of the problem. Two subgrid drag models are proposed and tested on both academic and laboratory configurations.

My first semester pursuing my MFA in Voice and Speech Pedagogy I vocal-coached an openly gay student playing a straight character who would mask his sexual identity in such a manner that his performance became stiff and uninteresting. Rather than using his personal identity as an asset in the pursuit of a successful performance, his chosen vocal tactics removed any sense of theatricality from his performance. I confronted the student and suggested such extreme vocal suppression diminished the quality of his overall performance. He replied, "So you want me to get the gay out."His use of the phrase, "get the gay out" to describe a fuller adaptation of his sexual identity to suit the character fascinated me and led to me to create a performance seminar course that used open acknowledgment of Camp performance styles as a valuable way to prepare students, gay or straight, for careers on the stage and screen. This thesis is a record of the course taught in the spring of 2007; CAMP: RIDICULOUS THEATRE AS SERIOUS DRAMA.

La thèse porte sur l'étude de la réduction de traînée par injection de bulles. La réduction de traînée présente un intérêt pour les applications navales puisqu'elle est issue d'une modification des structures cohérentes qui contribuent le plus à la résistance à l'avancement. Le but de cette étude est d'analyser les mécanismes à l'origine de cette diminution du frottement pariétal. L'approche utilisée dans le cadre de cette étude est numérique, elle emploie le code JADIM par une approche Euler-Lagrange : la phase continue est simulée par Simulation Numérique Directe et la phase dispersée est simulée en suivant individuellement chaque bulle. La configuration retenue dans le cadre de cette étude est celle de l'écoulement de Taylor-Couette (écoulement compris entre deux cylindres en rotation). La première partie de la thèse vise à adapter l'outil numérique employé, afin de pouvoir prendre en compte le retour de la phase dispersée via des termes de forçage dans les équations bilan de matière et de quantité de mouvement. La deuxième partie de la thèse vise à étudier l'écoulement porteur en configuration monophasique, afin de disposer d'une référence sur l'écoulement non perturbé. La troisième partie de la thèse a pour objectif d'étudier la dispersion passive des bulles dans le système, afin d'analyser les mécanismes de migrations mis en jeu. Enfin la dernière partie de la thèse vise à étudier l'influence des bulles sur l'écoulement porteur en analysant l'effet de certains paramètres, notamment le taux de vide et la flottabilité. / The study deals with drag reduction induced by bubble injection, its application concerns naval transport. The aim of the study is to shed more light on mechanisms that are involved in this wall friction reduction. The study is based on a numerical approach, and use the JADIM code with an Euler-Lagrange approach: the continuous phase is solved by Direct Numerical Simulation, and the disperse phase by a tracking of each bubble. Within the framework of this study we consider the Taylor-Couette flow configuration (flow between two concentric cylinders in rotation). The first part of the study deals with the modification of the numerical tool, in order to take into account the influence of the disperse phase on the continuous one through forcing terms in the mass and momentum balance equations. The aim of the second part is to study de Taylor-Couette flow in its monophasic configuration, for the purpose of providing a reference of the undisturbed flow. The third part deals with the passive dispersion of bubble in Taylor-Couette flow, in order to analyze the migration mechanisms involved. And the aim of the last part is to study the effects of the disperse phase on the continuous one, by analyzing the influence of bubbly phase parameters (like void fraction and buoyancy).

Doctor of Philosophy / Department of Agronomy / Tesfaye T. Tesso / The lack of effective post-emergence weed control options is often highlighted as one of the major factors behind dwindling acreage under sorghum (Sorghum bicolor (L.) Moench) in the United States. The discovery of herbicide resistance sources in wild sorghum population and subsequent efforts to incorporate them into cultivated sorghum was received with much optimism to change weed management practices in sorghum. As the development of the technology advances, especially of the Acetolactate synthase (ALS) resistance, concerns over the temporary interveinal chlorosis and reduced seedling vigor in some of the resistant families became heightened. This thesis research is designed to shed light on the genetic basis of seedling chlorosis and assess its impacts on yield potential. The study has three parts; the first part is focused on identifying the genetic causes and plant mechanisms associated with the chlorotic phenotype. ALS herbicide resistant sister-lines expressing normal and chlorotic phenotypes were analyzed via RNA sequencing at four time points during seedling growth. The study identified several variants of genes coding chloroplast precursors and those that cause epigenetic modifications. Once confirmed, genetic markers can be developed to track these gene variants in the breeding population and eliminate segregates genetically prone to chlorosis/yellowing. The second part of the study focuses on assessing the effect of ALS resistance associated chlorosis on agronomic and nutritional parameters of sorghum inbred lines. A set of ALS resistant lines expressing different levels of the chlorotic phenotype were evaluated in replicated field trials and laboratory methods. Results showed that interveinal chlorosis delays flowering but does not have negative effect on yield and nutritional parameters with and without herbicide treatment. The last part addresses whether there is any yield drag that may be associated with herbicide resistance traits and foliar interveinal chlorosis. For this, we synthesized a large set (182) of hybrids from ALS resistant, ACCase resistant and regular (susceptible) seed and pollinator parents. The hybrids were then evaluated in three sets at multiple locations during the 2014 and 2015 crop seasons along with commercial checks. The results revealed that resistance to both herbicides do not cause any drag to grain yield. The traits also do not have any negative impact on grain and nutritional quality of resistant hybrids.

Smith (1919, loc 1980) believed the dragon reflected society?s fears and aspirations of the last fifty centuries and beyond, because dragons evolved along with civilization itself. This dissertation investigates the representations of notable dragons from different contexts and concludes that there is a connection between the imaginary about dragons and men?s relationship with nature. / O drag?o sobrevoa a humanidade desde a Idade Antiga, ele faz parte de mitos e hist?rias do Ocidente e Oriente, Antigo e Novo Mundos, rastejou pela cultura de sociedades que supostamente nunca se encontraram, da asteca ? chinesa, da n?rdica ? hindu?sta. Para Smith (1919, loc 1980), o drag?o vem refletindo os medos e aspira??es da humanidade por mais de cinquenta s?culos, pois desenvolveu-se com a pr?pria civiliza??o.

The purpose of the study was to examine whether gender moderated the association between psychopathic traits and peer harassment, as well as examining each psychopathic trait individually alongside the different harassment forms. Secondary data from the Seven School project was used which collected its data from seven middle-sized schools in Sweden. Besides descriptive and correlation analyses, a series of hierarchical regression models were used. The results show that boys in general scored higher than girls on both psychopathic traits and peer harassment. Also, impulsivity predicted peer harassment and so did gender in all outcome steps except for step 1 and 2 for personal harassment. However, gender didn’t moderate the effect between psychopathic traits and peer harassment except for sexual harassment and impulsivity. The conclusion of the study is that impulsivity is a major concern in peer harassment whilst grandiosity and callous-unemotional does not seem to be of major concern. Also, the moderating role of gender only had an effect on impulsivity and sexual harassment in males. / Syftet med studien var att undersöka om kön modererade kopplingen mellan psykopatiska drag och trakasserier bland jämnåriga. Samt även att undersöka de olika psykopatiska dragen separat tillsammans med de olika trakasserierna. Sekundärdata från ”Sju skolor” projektet användes som hämtade in sin data från sju medelstora skolor i Sverige. Utöver descriptive- och korrelationsanalyser, utfördes även en serie av hierarkiska regressionsmodeller. Resultatet visar på att pojkar generellt får högre resultat på psykopatiska drag och trakasserier än flickor. Impulsivitet förutsäger trakasserier bland jämnåriga och det gjorde även kön i alla resultatsteg förutom steg 1 och 2 för personliga trakasserier. Däremot så modererar kön inte effekten mellan psykopatiska drag och trakasserier förutom sexuella trakasserier och impulsivitet. Slutsatsen av studien är den att impulsivitet är ett stort problem för trakasserier bland jämnåriga medan grandiositet och känslokallhet inte verkar vara ett större problem. Den modererande koppling mellan könen hade bara en effekt på impulsivitet och sexuella trakasserier bland män.
