This dissertation examines the conflict over slavery and freedom in Philadelphia from 1820 to 1847. As the northernmost southern city in a state that bordered three slave states, Philadelphia maintained a long tradition of abolitionism and fugitive slave activity. Conflicts that arose over fugitive slaves and the kidnapping of free African-Americans forced Philadelphians to confront the politics of slavery. This dissertation argues that until 1847, Pennsylvania was in effect a slave state. The work of proslavery groups, namely slave masters, their agents, white and black kidnappers, and local, state, and national political supporters, undermined the ostensible successes of state laws designed to protect the freedom of African-Americans in Pennsylvania. Commonly referred to as “liberty laws,” this legislation exposed the inherent difficulty in determining the free or enslaved status of not only fugitive slaves but also African-American kidnapping victims. By studying the specific fugitive or kidnapping cases that inspired these liberty laws, one finds that time and again African-Americans and their allies forced white politicians to grapple with the reality that Pennsylvania was not a safe-haven for African-Americans, regardless of their condition of bondage or freedom. Furthermore, these cases often precipitated into desperate rescues and bloody riots on the streets of Philadelphia; these civil wars in miniature reflected the negotiated and compromised realities of living while black in the city. Ordinary African-Americans living in Philadelphia bore the burden of comity, or friendly relations between states, by practicing what I term “street diplomacy”: the up-close and personal struggles over freedom and slavery that had local, state, and national ramifications. In a larger sense, street diplomacy in Philadelphia magnified the stakes of national comity, i.e. the Union, by showcasing how dividing states by their condition of bondage remained impossible due to permeable geographic borders that fostered perpetual fugitive slave and kidnapping crises. Thus, this dissertation argues that African-Americans and their allies’ struggles with slave-masters, slave-catchers, kidnappers and proslavery politicians disrupted the best efforts of white politicians to maintain a compromised and compromising Union. / History

Cette thèse se propose d'appréhender le parcours du dramaturge américain Tennessee Williams en démontrant qu'il existe une authentique dimension engagée dans son œuvre. Ceci va à l'encontre de la critique traditionnelle qui tend à le dépeindre comme l'homme de la nostalgie et du rêve, le dramaturge apolitique du désir et des passions, en faisant abstraction du contexte idéologique. Or, Williams a commencé sa carrière dans les années trente comme écrivain protestataire en produisant de violentes pièces de dénonciation dans la tradition du théâtre de gauche. L'analyse de ces pièces écrites entre 1936 et 1938 – Candles to the Sun, Fugitive Kind, Spring Storm et Not About Nightingales – permet de rendre intelligible le parcours d'un dramaturge qui s'est toujours défini comme un révolutionnaire et revendique sa conscience sociale comme l'élément déterminant de son œuvre. Dans ces pièces, il intègre les stratégies formelles du théâtre de gauche comme le réalisme révolutionnaire ou l'esthétique du Front Populaire tout en créant des œuvres atypiques qui se distinguent de la production de l'époque. Préférant l'ambiguïté à des messages clairs ou didactiques, il inscrit ses premiers écrits sous le signe de la non clôture et joue avec les mécanismes identificatoires. Théâtre de l'émotionnel, son théâtre parait être à l'opposé de celui de Brecht. Pourtant son impact est souvent remarquablement similaire. C'est finalement en théorisant le phénomène des identifications fluctuantes que l'on peut comprendre la manière dont Williams s'approprie les fondements du théâtre de Brecht en en transposant les structures stéréoscopiques. Ceci nous conduit à redéfinir l'engagement au théâtre. / The object of my thesis is to reconsider the critical studies on Tennessee Williams by focusing on the political dimension of his early work. This is done by analysing the protest plays he wrote in the 1930s: Candles to the Sun, Fugitive Kind, Spring Storm and Not about Nightingales. These seminal plays reveal a virtually unknown Tennessee Williams, committed to fighting social injustice. This discovery is all the more important as the dramatist is often portrayed as an apolitical writer and described as a poet of the flesh and a depictor of sexual instincts and conflicts. This approach challenges the conventional vision of Williams' literary ambitions by showing that he may have been more socially and even politically subversive than generally admitted. A careful reading of Williams’s plays written in the thirties reveals that he closely followed the developments of left-wing theatre both in the choice of his subjects and of dramaturgical forms such as revolutionary realism or the aesthetics of the Popular Front. Still, he created original plays that went far beyond rigid formulaes or predictable plots. Because they propose no clearcut message, and through their permeating ambiguity and the feelings of empathy they trigger, these plays radically differ from the other productions of the period. Williams’ theatre could be described as a theatre of emotions at the opposite of Brecht’s theatre of alienation. However its impact is often remarkably similar. This can be explained by the phenomenon of fluctuating identifications that is Williams’s way of absorbing Brecht’s stereoscopic structures. This leads us to redefine the very principles of commitment in the theatre.

L’érosion éolienne des matières granulaires (minerais, charbons,. . . ) est un des facteurs influençant grandement la qualité de l’air dans l’environnement proche de nombreux sites industriels. L’objectif principal de ce travail est l’amélioration des méthodologies de quantification des émissions des sources diffuses, notamment à partir d’une meilleure prise en compte de l’exposition éolienne des sources que sont les tas de stockage et des répartitions granulométriques des matières présentes sur les sites de stockage. Les observations sur sites industriels montrent que les régions proches des tas de stockage de matières granulaires sont chargées de particules de granulométries plutôt fines. Celles-ci sont susceptibles d’être remises en suspension par les structures tourbillonnaires générées par le vent incident. Ainsi, ces zones d’envol potentiel ont fait l’objet d’analyses afin de quantifier leur contribution aux émissions globales. Une technique de visualisation d’écoulement pariétal, associée à des simulations numériques tridimensionnelles, ont été mises en oeuvre pour mieux comprendre ces structures de l’écoulement. Les matières granulaires sont un mélange de particules érodibles et non-érodibles. Le caractère érodible étant lié aux propriétés des particules (principalement granulométrie et masse volumique), ainsi qu’à la vitesse du vent incident. Dans ce cadre, deux types d’études ont été menées: des essais expérimentaux d’envol de particules dans une soufflerie et des simulations numériques tridimensionnelles avec un logiciel open-source de mécanique des fluides (Code_Saturne). Une technique originale a ainsi été développée pour quantifier, par une pesée en continue, l’influence des particules non-érodibles sur le flux massique envolé. En parallèle, le comportement des particules sur la surface est analysé à l’aide de clichés photographiques. L’analyse de l’effet des particules non-érodibles au niveau local est réalisée grâce à des simulations numériques pour des configurations polydispersées. Les résultats présentés dans ce mémoire constituent de premiers éléments pouvant possiblement contribuer à l’amélioration des modèles actuels de quantification des émissions de particules par une meilleure intégration et pris en compte de la présence de particules non-érodibles pour les matières présentant de larges spectres granulométriques. / Wind erosion of granular materials (ores, coal, ...) is one of the factors that greatly influence the quality of the air in the immediate vicinity of many industrial sites. The main objective of this work is the improvement of methodologies for quantifying emissions from diffuse sources. It may be carried out by a better consideration of wind exposure on the sources (storage piles) and larger size distributions of granular materials present at the storage sites. Observations show that areas near storage piles of granular materials on industrial sites are loaded with silt particles. These particles may be re-emitted by vortex structures. Thus, these areas of potential particles take-off were analyzed to quantify their contribution to global emissions. A wall flow visualization technique associated with three-dimensional numerical simulations have been implemented. Granular material is a mixture of erodible and non-erodible particle. The erodible character may be associated to particle properties (mainly size and density), as well as the ambient wind speed. In this context, two types of studies were conducted: experimental tests of particles take-off in a wind-tunnel and numerical simulations with a three-dimensional open-source fluid dynamics code (Code_Saturne). An original technique has been developed to quantify, by a continuous weighing, the influence of non-erodible particles of the mass flow. In parallel, the behaviour of particles on the surface is analyzed using photographs. The analysis of the effect of nonerodible particles at local level is achieved through numerical simulations for poly-dispersed configurations. The results presented in this thesis are the first elements that can potentially contribute to the improvement of current models of quantification of particulate emissions through a better integration of the presence of non-erodible particles for materials with large particle size spectra.

Mad Pursuits: Therapeutic Narration in Postwar American Fiction examines three mid-century American novels—J.D. Salinger’s The Catcher in the Rye (1951), Ralph Ellison’s Invisible Man (1952), and Sylvia Plath’s The Bell Jar (1963)—in relation to the rise and popularization of psychoanalytic theory in America. The study historicizes these landmark novels as representing and interrogating postwar America’s confidence in the therapeutic capacity of narrative to redress psychological problems. Drawing on key concepts from narrative theory and the multidisciplinary field of narrative and identity studies, I argue that these texts develop a multi-layered, formal problematization of therapeutic narration: the narrativization of the self through modes of interpretation based on character action and development. The study, thus, investigates how the texts both critique the purported effectiveness of being healed through narrative means, as well as how they problematize their society’s investment in this method. I propose that the novels ultimately explore submerged possibilities for realizing what I call fugitive selves by creating self-representations that negotiate and exceed the confines of the paradigmatic models of plot and character of the period. In Chapter One, I argue that the ego and pop psychological movements during the postwar era encouraged the American public to define and realize psychological health, success and happiness through narrativized means. I show in Chapter Two how careful differentiation between narrative levels of interpretation in The Bell Jar reveals the novel’s complication of the self created in narrative, with and against the socio-cultural scripts and therapeutic assumptions of the period. Chapter Three concentrates on The Catcher in the Rye’s various methods of de-composing the narrative identity of the subject created through developmental and therapeutic narration. In the final chapter, I read Invisible Man as a satire of postwar psychoanalytic theory and method specifically concerning racialized narrative identities, and as a reflection on a method of enduring psychological illness. The Conclusion brings together several argumentative strands running throughout the dissertation regarding what the novels contrastively reveal about the perils, and even the possibilities, inherent in the narrativizing of the self in early postwar America.

O ozônio, formado por reações fotoquímicas, é um dos principais componentes do smog fotoquímico. Devido às suas características oxidantes ele é prejudicial à saúde e ao meio ambiente. Por ser um poluente secundário, o controle dos níveis de ozônio na troposfera deve ser realizado a partir da redução dos seus principais precursores: COVs e óxidos de nitrogênio. Refinarias de petróleo são importantes fontes de COVs, especialmente de emissões fugitivas de componentes de linhas de processo e, portanto, são fontes onde há potencial para reduzir estas emissões. Além disso, as licenças ambientais das refinarias também exigem a redução de emissões fugitivas de COVs. A metodologia LDAR, baseada no uso de um analisador portátil para identificação de vazamentos em componentes de linhas de processo, vem sendo utilizada nos Estados Unidos desde a década de 70 para a redução das emissões fugitivas de COVs em refinarias de petróleo. É uma metodologia bastante intensiva em mão de obra e tem custo elevado, uma vez que exige o monitoramento individual de milhares de componentes existentes em uma planta industrial para a detecção de vazamentos. Porém, estudos mostram que o controle com foco nos grandes vazamentos permite uma redução mais efetiva das emissões fugitivas e com menor custo. A metodologia Smart LDAR, que consiste no uso de imagem ótica de infravermelho para visualização de gases, permite a identificação dos grandes vazamentos, que são os que mais contribuem para as emissões fugitivas, sem que haja necessidade de medição de todos os componentes das linhas de processo. O objetivo desta pesquisa é avaliar as metodologias LDAR (Leak Detection and Repair) e Smart LDAR, utilizadas para o controle de emissões fugitivas de compostos orgânicos voláteis (COVs) em refinaria de petróleo, utilizando o conceito de custo-efetividade. Os resultados obtidos a partir das avaliações realizadas mostraram que a metodologia Smart LDAR tem melhor relação custo efetividade para o controle de emissões fugitivas de COVs em comparação à metodologia LDAR convencional / The impact on air quality caused by air pollutants emissions has proven to be a growing environmental problem, mainly at urban centers and industrial areas. The ozone, formed through photochemical reactions, is the photochemical smog’s major component. Due its oxidizing characteristics, it is harmful to the healthy and to the environment. Due to de fact to be a secondary pollutant, the ozone control in the troposphere must be achieved by reducing emissions from its main precursors: VOCs and nitrogen oxides. Petroleum refineries are significant sources of VOCs, especially of fugitive emissions from process lines’ components, so they are sources with potential to reduce these emissions. Furthermore, the petroleum refineries’ environmental licenses also demand the reduction of VOCs’ fugitive emissions. The LDAR methodology, which is based on the application of a portable analyzer to identify leaks in process lines’ components, has been used in the US since the 70s to reduce VOCs’ fugitive emissions in petroleum refineries. This methodology is quite intensive hand labor and costly, since an industrial plant has thousands of components that must be measured individually to detect leaks. However, studies show that the control focusing on large leaks allows the reduction of fugitive emissions more effectively and with low costs. The methodology known as Smart LDAR, which uses infrared optical image for gas leaks view, has the potential to identify great leaks, that most contribute to the fugitive emissions, without requirement to measure all process lines’ components. The purpose of this research is evaluate the methodologies LDAR (Leak Detection and Repair) and Smart LDAR, used to control volatile organic compounds’ (VOCs) fugitive emissions in petroleum refineries, using the concept of cost-effective analysis. The results obtained from the evaluations of this study showed that the Smart LDAR methodology has the best cost effective relation to control fugitive emissions compared to the LDAR conventional methodology

Indiana University-Purdue University Indianapolis (IUPUI) / This thesis examines Mark Twain’s use of the dialectic between the characters Huck and Jim to illuminate Jim’s humanity in the classic novel Adventures of Huckleberry Finn. Over the course of their adventure, Huck learns that Jim is a human being and not property. This realization leads Huck to choose to assist Jim in his escape from captivity, and risk eternal damnation according to his religious beliefs. Huck’s decision is driven by the friendship that develops between him and his fellow fugitive on their adventure. Jim’s kindness and stewardship also provide a stark contrast to the treachery of the characters on the banks of the river. Twain thus crafts a message that slavery and race discrimination are wrong without taking the tone of an abolitionist, combining an amusing children’s story with a profound social message. Although definitive proof of his intention to do so has never been found, human friendship is the sliver of common ground Twain used to reach across the profound racial gap in the United States in the late 19th century. The analysis takes place in four parts: (1) a comparison of AHF to other nineteenth century works that featured slavery to establish it as unique among those works; (2) an analysis of the aforementioned dialectic from a modern text of the novel featuring previous deleted parts from the early manuscript; (3) a review of the critical response to the novel which reveals that if Twain was trying to send a message of racial equality, he was not doing so overtly; and (4) a conclusion in which I posit that Twain found a creative solution to a social problem and cite critical discourse that notes Twain’s course of action. This yielded a work that was both more widely read and timeless than a work that confronted slavery directly. Chapters one, three and four utilize critical dialogue and history from print and digital sources. Jane E. Schultz, Ph.D., Professor
