The Idiosyncratic Body: Contemporary Clown Theory and Practice

Drawing on historical research, personal interviews, performance analysis, and my own embodied experience as a participant-observer in several clown workshops, I explore the diverse historical influences on clown theatre as it is conceived today. I then investigate how the concept of embodied knowledge is reflected in red-nose clown pedagogy. Finally, I argue that through shared embodied knowledge spectators are able to perceive and appreciate the humor of clown theatre in performance. I propose that clown theatre represents a reaction to the eroding personal connections prompted by the so-called information age, and that humor in clown theatre is a revealing index of socio-cultural values, attitudes, dispositions, and concerns.

Slot Film Cooling: A Comprehensive Experimental Characterization

When components of a propulsion system are exposed to elevated flow temperatures there is a risk for catastrophic failure if the components are not properly protected from the thermal loads. Among several strategies, slot film cooling is one of the most commonly used, yet poorly understood active cooling techniques. Tangential injection of a relatively cool fluid layer protects the surface(s) in question, but the turbulent mixing between the hot mainstream and cooler film along with the presence of the wall presents an inherently complex problem where kinematics, thermal transport and multimodal heat transfer are coupled. Furthermore, new propulsion designs rely heavily on CFD analysis to verify their viability. These CFD models require validation of their results, and the current literature does not provide a comprehensive data set for film cooling that meets all the demands for proper validation, namely a comprehensive (kinematic, thermal and boundary condition data) data set obtained over a wide range of conditions. This body of work aims at solving the fundamental issue of validation by providing high quality comprehensive film cooling data (kinematics, thermal mixing, heat transfer). 3 distinct velocity ratios (VR=uc/u∞) are examined corresponding to wall-wake (VR~0.5), min-shear (VR ~ 1.0), and wall-jet (VR~2.0) type flows at injection, while the temperature ratio TR= T∞/Tc is approximately 1.5 for all cases. Turbulence intensities at injection are 2-4% for the mainstream (urms/u∞, vrms/u∞,), and on the order of 8-10% for the coolant (urms/uc, vrms/uc,). A special emphasis is placed on inlet characterization, since inlet data in the literature is often incomplete or is of relatively low quality for CFD development. The data reveals that min-shear injection provides the best performance, followed by the wall-jet. The wall-wake case is comparably poor in performance. The comprehensive data suggests that this relative performance is due to the mixing strength of each case, as well as the location of regions of strong mixing with respect to the wall. Kinematic and thermal data show that strong mixing occurs in the wall-jet away from the wall (y/s>1), while strong mixing in the wall-wake occurs much closer to the wall (y/s<1). Min-shear cases exhibit noticeably weaker mixing confined to about y/s=1. Additionally to these general observations, the experimental data obtained in this work is analyzed to reveal scaling laws for the inlets, near-wall scaling, detecting and characterizing coherent structures in the flow as well as to provide data reduction strategies for comparison to CFD models (RANS and LES).

BROMANCE : les paradoxes des stratégies homosociales

Depuis les années 2000, l’apparition du terme Bromance marque la culture populaire américaine. Cette notion est apparue pour définir les amitiés entre hommes au cinéma, à la télévision et sur Internet. Les films de Bromance, caractérisés par une multitude de scènes de déclaration d’amour entre hommes, traduisent bien cette nouvelle façon d’aborder l’amitié au masculin. À travers les définitions de la masculinité dans ces films, l’enjeu de l’hétérosexualité demeure omniprésent. Malgré la fragilisation de certains stéréotypes traditionnels liés au masculin, il n’en demeure pas moins que la notion de «vraie» masculinité persiste et demeure systématiquement liée à l’hétérosexualité des hommes qui partagent cette amitié particulière qu’on appelle Bromance. Dans cette optique, plusieurs stratégies se manifestent pour prouver la masculinité et donc l’hétérosexualité des protagonistes, mais l’une d’entre elles semble être au cœur de ces films. Cette stratégie s’incarne sous la forme d’une compétition entre hommes qui mise sur la capacité à performer un acte conventionnellement associé à l’homosexualité. Sur Internet, des vidéos qui prennent le nom « Gay Chicken » présentent des hommes qui s’embrassent et qui se touchent sans être dérangés ou ébranlés. C’est la capacité à être calme et en contrôle en restant insensible au corps d’un autre homme qui démontrerait le côté inébranlable de son hétérosexualité et donc de sa masculinité. C’est cet esprit du « Gay Chicken » qui se retrouve un peu partout dans l’univers des films de Bromance. Paradoxalement, ces nouveaux «modèles» d’homme doivent pouvoir à la fois incarner une masculinité plus flexible, plus ouverte et sensible, mais doivent également prouver leur virilité. Cette « masculinité contemporaine » brouille les cartes entre ce qui est viril et ce qui ne l’est pas, entre ce qui est féminin et ce qui ne l’est pas et entre ce qui est homosexuel et ce qui ne l’est pas. Les relations homosociales dans le cadre de Bromances présentent alors des opportunités indispensables pour prouver à tous la force de son hétérosexualité. Ce travail de recherche se penchera donc plus précisément sur les paradoxes d’une « masculinité contemporaine » intimement liée à l’orientation hétérosexuelle, par l’entremise de certains films issus de la culture populaire américaine associée à la Bromance. L’objectif est de montrer comment ces films sont des manifestations significatives d’une nouvelle forme d’affirmation identitaire masculine qui passe par des relations homosociales où les tensions et sous-textes homosexuels se multiplient et doivent être réprimés ou invalidés continuellement.

Adaptação do paradigma orientado a notificações para desenvolvimento de sistemas fuzzy

This work proposes to adjust the Notification Oriented Paradigm (NOP) so that it provides support to fuzzy concepts. NOP is inspired by elements of imperative and declarative paradigms, seeking to solve some of the drawbacks of both. By decomposing an application into a network of smaller computational entities that are executed only when necessary, NOP eliminates the need to perform unnecessary computations and helps to achieve better logical-causal uncoupling, facilitating code reuse and application distribution over multiple processors or machines. In addition, NOP allows to express the logical-causal knowledge at a high level of abstraction, through rules in IF-THEN format. Fuzzy systems, in turn, perform logical inferences on causal knowledge bases (IF-THEN rules) that can deal with problems involving uncertainty. Since PON uses IF-THEN rules in an alternative way, reducing redundant evaluations and providing better decoupling, this research has been carried out to identify, propose and evaluate the necessary changes to be made on NOP allowing to be used in the development of fuzzy systems. After that, two fully usable materializations were created: a C++ framework, and a complete programming language (LingPONFuzzy) that provide support to fuzzy inference systems. From there study cases have been created and several tests cases were conducted, in order to validate the proposed solution. The test results have shown a significant reduction in the number of rules evaluated in comparison to a fuzzy system developed using conventional tools (frameworks), which could represent an improvement in performance of the applications.

Aplicação de modelos de equações estruturais no estudo da eficácia de Sistemas de Gestão de Desempenho

Para fazer face às exigências da sociedade, as organizações têm a necessidade de desenvolver esforços de modo a aumentar a sua performance, através de práticas de gestão estratégica de recursos humanos. Nesta dissertação iremos aprofundar o estudo do modelo proposto por Marr (2009) para explicar a Cultura Orientada para o Desempenho e demonstrar os efeitos que a cultura tem nos Sistemas de Gestão de Desempenho, utilizando os Modelos de Equações Estruturais, através da análise de respostas obtidas sobre 325 colaboradores de empresas portuguesas do sector público e privado. Desta análise resultou a confirmação das quatro dimensões latentes de Cultura Organizacional propostas pelo autor, através da Análise Factorial Confirmatória, revelando também a sua importância e contributos diferenciados no Sistema de Gestão de Desempenho de uma organização. De um modo geral, verificou-se que as dimensões da Cultura contribuem de forma positiva para o aumento da eficácia de um Sistema de Gestão de Desempenho, alinhado com o modelo conceptual proposto e enfatizando a importância de se estudar as dimensões de Cultura e de Sistemas de Gestão de Desempenho de forma simultânea.

Influência do uso de combustíveis alternativos na síntese por combustão via microondas para a produção de materiais cerâmicos com estrutura espinélio

The development and study of detectors sensitive to flammable combustible and toxic gases at low cost is a crucial technology challenge to enable marketable versions to the market in general. Solid state sensors are attractive for commercial purposes by the strength and lifetime, because it isn t consumed in the reaction with the gas. In parallel, the use of synthesis techniques more viable for the applicability on an industrial scale are more attractive to produce commercial products. In this context ceramics with spinel structure were obtained by microwave-assisted combustion for application to flammable fuel gas detectors. Additionally, alternatives organic-reducers were employed to study the influence of those in the synthesis process and the differences in performance and properties of the powders obtained. The organic- reducers were characterized by Thermogravimetry (TG) and Derivative Thermogravimetry (DTG). After synthesis, the samples were heat treated and characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-ray Diffraction (XRD), analysis by specific area by BET Method and Scanning Electron Microscopy (SEM). Quantification of phases and structural parameters were carried through Rietveld method. The methodology was effective to obtain Ni-Mn mixed oxides. The fuels influenced in obtaining spinel phase and morphology of the samples, however samples calcined at 950 °C there is just the spinel phase in the material regardless of the organic-reducer. Therefore, differences in performance are expected in technological applications when sample equal in phase but with different morphologies are tested

Crisis de la masculinidad hegemónica: (re)escrituras finiseculares de la batalla de los sexos en Estados Unidos

The present dissertation explores the concept of masculinity as power, paying special attention to the production and resistance of the rigid narratives of masculinity. Such configuration has prescribed the role of men in society—both at an individual and collective level—placing man at the centre of the patriarchal system and thus conferring upon men superiority over women. Such ideological construction is based on an essentialist view of the world, where biology determines destiny. As Men’s Studies have been advocating since their emergence, the victims of such an inegalitarian system are mainly women, but there are others, such as marginalized groups of men and hegemonic men themselves. Our focus is centered on the so-called crisis of masculinity that North American men went through in the last two decades of the twentieth century, the consequences of which have not yet been completely overcome. While from an essentialist point of view such a crisis is questionable, the political, economic and sociological reality of the Reagan’s Age made visible the downsides and pitfalls of toxic masculinity. In order to face the problems derived from the damaging nature of a construction that constrains men, three broad responses to the problem were taken: pro-feminist, anti-feminist and spiritual. Except for pro-feminists, the main reaction of these groupings consisted of victimizing themselves and of defending their essentialist supremacy—lulled by the fantasy world fostered by the “politics of symbolism” (Dallek, 1999 [1984]) of Reagan’s escapist policies. Opposing this reassuring image of the United States, the Blank Generation addressed the crisis of masculinity from a nihilist perspective. Through the analysis of American Psycho, this dissertation will illustrate the darkest side of the hegemonic model of masculinity...

Relatório final de estágio pedagógico realizado na Escola Básica Secundária José Gomes Ferreira

A necessidade de um profissional reflexivo é a base que sustenta a realização deste relatório de estágio. A reflexão sobre a ação permite que o professor possa melhorar o seu processo de ensino-aprendizagem conduzindo a uma melhoria tanto no seu desempenho como nodos seus alunos. Para além de reflexivo o professor deve procurar inovar a sua ação. Com isto, torna-se essencial que saiba ser crítico e fundamentar as suas decisões cientificamente definindo as suas ideias com base em pressupostos científicos que também deverão ser questionados por si. A participação na escola e comunidade através de atividades como desporto escolar ou a direção de turma pressupõem que o professor tenha uma formação inicial devidamente abrangente que lhe permita abordar da melhor forma os vários desafios da comunidade escolar. Como professor estagiário todas estas componentes que formam um "bom professor" foram experienciadas neste processo de supervisão pedagógica. Torna-se imperativo que este processo finda com uma reflexão crítica que abranja todas as áreas de desenvolvimento de competências do professor.

A influência da Ansiedade nas Competências dos Alunos da Academia Militar: Estudo de caso dos Exercício Finais - Leão 15

O presente estudo subordinado ao tema “A influência da Ansiedade nas Competências dos Alunos da Academia Militar: Estudo de caso dos Exercício Finais - Leão 15”, tem como principal finalidade identificar e quantificar a influência da ansiedade nas competências de liderança dos Cadetes-Alunos da Academia Militar. Contribuindo assim, para o reconhecimento das competências influenciadas pela ansiedade e a sua perceção no desempenho, mais propriamente na Informação Comportamental do Aluno. No estudo foi implementado um inquérito constituído por algumas questões de caráter sociodemográfico, um questionário de competências de liderança e um questionário de medição de ansiedade – STAI. Foi aplicado a um grupo de 165 Cadetes-Alunos da Academia, sendo 95 do 4º Ano Escolar e 80 do 1º Ano Escolar. De salientar que este inquérito foi realizado duas vezes: antes e depois do Exercício Leão 15. Com base nas respostas dadas, criou-se uma base de dados em Microsoft Excel, à qual se acrescentaram as notas de Informação Comportamental dos Aluno, e procedeu-se ao seu tratamento e análise estatística, com recurso ao Statistical Package for Social Sciences. (SPSS) Dos resultados obtidos identificaram-se várias diferenças significativas entre os níveis de ansiedade e as competências de liderança, relativamente ao género, ano escolar, curso, ao desporto mais praticado e ao período em análise do Exercício Leão 15 das quais se realçam: o género feminino revelou maior índice de ansiedade no período anterior ao Exercício; o 1ºAno Escolar revelou maior índice de ansiedade estado em ambos os períodos; o curso de EXE-Engenharias revelou maior ansiedade estado e ansiedade traço no período antes do Exercício e os alunos que praticam mais frequentemente desporto coletivo revelam maior Ansiedade Estado no período depois do Exercício Leão 15. Assinalaram-se ainda correlações significativas entre a ansiedade, as competências de liderança e a nota da Informação Comportamental dos Aluno com valores mais elevados nas seguintes: “trabalho de equipa e coesão”; “flexibilidade e adaptabilidade”; “autocontrolo” e “influência e referência”. Com o objetivo de procurar identificar e quantificar as competências mais influenciadas pela ansiedade, concluiu-se que as médias de ansiedade como variável preditora é maior nas competências: “flexibilidade e adaptabilidade”, “capacidade de resolver problemas”, “reconhecimento, feedback positivo e valorização”, “aptidão técnico profissional”, “gestão de conflitos e negociação”, “transparência”, “comunicação assertiva”, “comunicação” e “relações interpessoais”.

Effects of infiltration pressure on mechanical properties of Al–12Si/graphite composites for piston engines

In this work results for the flexural strength and the thermal properties of interpenetrated graphite preforms infiltrated with Al-12wt%Si are discussed and compared to those for packed graphite particles. To make this comparison relevant, graphite particles of four sizes in the range 15–124 μm, were obtained by grinding the graphite preform. Effects of the pressure applied to infiltrate the liquid alloy on composite properties were investigated. In spite of the largely different reinforcement volume fractions (90% in volume in the preform and around 50% in particle compacts) most properties are similar. Only the Coefficient of Thermal Expansion is 50% smaller in the preform composites. Thermal conductivity of the preform composites (slightly below 100 W/m K), may be increased by reducing the graphite content, alloying, or increasing the infiltration pressure. The strength of particle composites follows Griffith criterion if the defect size is identified with the particle diameter. On the other hand, the composites strength remains increasing up to unusually high values of the infiltration pressure. This is consistent with the drainage curves measured in this work. Mg and Ti additions are those that produce the most significant improvements in performance. Although extensive development work remains to be done, it may be concluded that both mechanical and thermal properties make these materials suitable for the fabrication of piston engines.

The Influence of HOPE VI Public Housing on Public Schools

In the United States, public school enrollment is typically organized by neighborhood boundaries. This dissertation examines whether the federally funded HOPE VI program influenced performance in neighborhood public schools. In effect since 1992, HOPE VI has sought to revitalize distressed public housing using the New Urbanism model of mixed income communities. There are 165 such HOPE VI projects nationwide. Despite nearly two decades of the program’s implementation, the literature on its connection to public school performance is thin. My dissertation aims to narrow this research gap. There are three principal research questions: (1) Following HOPE VI, was there a change in socioeconomic status (SES) in the neighborhood public school? The hypothesis is that low SES (measured as the proportion of students qualifying for the Free and Reduced Lunch Program) would reduce. (2) Following HOPE VI, did the performance of neighborhood public schools change? The hypothesis is that the school performance, measured by the proportion of 5th grade students proficient in state wide math and reading tests, would increase. (3) What factors relate to the performance of public schools in HOPE VI communities? The focus is on non-school, neighborhood factors that influence the public school performance. For answering the first two questions, I used t-tests and regression models to test the hypotheses. The analysis shows that there is no statistically significant change in SES following HOPE VI. However, there are statistically significant increases in performance for reading and math proficiency. The results are interesting in indicating that HOPE VI neighborhood improvement may have some relationship with improving school performance. To answer the third question, I conducted a case study analysis of two HOPE VI neighborhood public schools, one which improved significantly (in Philadelphia) and one which declined the most (in Washington DC). The analysis revealed three insights into neighborhood factors for improved school performance: (i) a strong local community organization; (ii) local community’s commitment (including the middle income families) to send children to the public school; and (iii) ties between housing and education officials to implement the federal housing program. In essence, the study reveals how housing policy is de facto education policy.

Comparación entre los efectos de un programa de entrenamiento de fuerza explosiva mediante bandas elásticas y un programa de entrenamiento con electro-estimulación de cuerpo completo

El objetivo del presente estudio fue analizar los cambios en el rendimiento en función de dos métodos de entrenamiento, el desarrollado mediante electro-estimulación muscular integral (EMI) frente a otro en el que se utilizaron bandas elásticas y que denominamos entrenamiento funcional con elásticos (EFE). La muestra estuvo compuesta por un grupo de diez (N=10) personas físicamente activas (23,04 ± 2,5 años). Se utilizó un diseño cuasi-experimental con medidas pre-post. Y fueron analizados los resultados de las pruebas: salto vertical con ayuda de brazos; y velocidad de desplazamiento en una carrera de ida y vuelta de 12 metros de distancia (6+6). Se realizó un análisis descriptivo de casos y medias. Y dado el tamaño de la muestra se calculó el tamaño del efecto, el cual fue bajo o moderado (d<0,5). Por último se compararon las diferencias de las medias de los grupos mediante la U de Mann Whitney, y las diferencias de las medias en función del tiempo (pre-post) mediante Friedman; en ambos casos los resultados no fueron significativos (p<0,5). En cuanto a los valores descriptivos del pre-post en ambos grupos: el grupo que entrenó con bandas elásticas obtuvo mejores resultados en ambas pruebas que el grupo que entrenó con EMI. En conclusión, el entrenamiento con bandas elásticas, a pesar de no ser significativo, parece mostrarse más efectivo que el entrenamiento con electro-estimulación muscular integral. Si bien, dadas las limitaciones del estudio estos datos hay que tomarlos con la pertinente cautela.
