This study of the extra-curricular activities of the Woodrow Wilson High School of Dallas, Texas, was made to determine who and why each of the activities developed, the life span of each, the percentage of the student body enrolled in the various groups, and the value of each extra-curricular activity from the viewpoint of the teachers, of the students, and of authorities in the field.

This document is an illustrated journey of my process as scenic designer for August Wilson's The Piano Lesson. produced by the University of Central Florida’s Conservatory Theater Program. The production opened on November 8, 2007 in the Backbox theatre on the university's main campus and closed on November 18, running for a total of eight performances. I begin by examining my role as the scenic designer for The Piano Lesson and follow with an explanation of experiences that were a result of the assignment. Through this process, I present a script analysis of the play, describe the design process through conversations with the artistic team, present visual research and follow it through "the build" process, to its final presentation on the UCF stage. As a whole, this paper is a comment on the potential that theater has to bring different cultures together and how I, a twenty-two year old white male, could connect with August Wilson's play The Piano Lesson1 which is rooted in the African American culture. Race is a major component that I explore throughout my reflection of my experience with The Piano Lesson. This paper also documents personal experiences that I had as a direct result of working on The Piano Lesson at the University of Central Florida. I document winning the National Award for Scenic Design in 2008 from the Kennedy Center American College Theater Festival for my design. I also report about the summer I spent at the Eugene O'Neill Theater Center, where The Piano Lesson was originally work-shopped in 1986. Finally, I write about my visit to the Hill District in Pittsburgh, PA, where August Wilson grew up and where The Piano Lesson is set Each of these experiences are connected to my initial assignment at the University of Central Florida as scenic designer for August Wilson's, The Piano Lesson.

La présente recherche porte sur la vie et l'œuvre de James Wilson Morrice (Montréal, 10 août 1865 - Tunis, Tunisie, 23 janvier 1924), en attachant davantage une importance particulière aux voyages de l'artiste aux Antilles et aux Caraïbes (1915-1924), retracés à travers ses incomparables dessins, croquis, pochades, aquarelles et peintures à l'huile. En considérant les arrière-plans familial, artistique et formatif sur lesquels advinrent subséquemment la vie et l'œuvre du peintre, l'ensemble des facteurs dynamiques qui orientèrent l'action de Morrice vers de tels lieux, les événements typiques de la vie de l'homme lors de ces pérégrinations exotiques et le dossier complet des documents de travail produits pour une œuvre (notes, croquis, esquisses, pochades, etc.), le texte identifie le cheminement de sa vision et les mécanismes profonds du processus de conception de l'esthétique caraïbe de l'artiste. / The present research relates on James Wilson Morrice's (Montréal, August 10n , 1865 - Tunis, Tunisia, January 23rd , 1924) life and work, specifically on the journeys of the artist in the Antilles and to the Carribbean islands (1915-1924) explained through his incomparable drawings, sketches, watercolors and oil paintings. By considering the family, the artistic and the formatif backgrounds on which happened subsequently the painter's life and work, the dynamic factors which directed Morrice's action to such places, the typical events of the man's life during these exotic wanderings and the complete file of working documents produced for a work (notes, drawings, sketches, etc.), the text identifies the progress of his vision and the deep mechanisms of the artist's Caribbean aesthetics conception process.

O objetivo desta dissertação é revisar os operadores laços de Wilson no contexto da correspondência AdS/CFT. Estes operadores, presentes em qualquer teoria de calibre, são importantes por nos fornecer um parâmetro de ordem para a transição de fase confinante/desconfinante. Além disso, eles são particularmente importantes no estudo da correspondência AdS/ CFT pois: i) Eles nos dão, em alguns casos, resultados exatos graças ao fato de poderem ser localizados em um modelo de matrizes, desta forma nos permitindo fazer testes altamente não triviais da correspondência; ii) Eles são os objetos da teoria de calibre que são duais as cordas propagando no interior do espaço, nos dando um rico dicionário entre quantidades no interior (AdS) e na borda do espaço (CFT). Depois de revisarmos os laços de Wilson em teorias de calibre e a correspondência Ads/CFT, introduziremos a definição dos laços de Wilson supersimétricos 1/2 BPS. Calcularemos eles para o caso de um acoplamento fraco e para qualquer outro valor da constante de acoplamento usando técnicas de modelos de matrizes. Finalmente, compararemos nossos resultados com computações de superfícies minimais no interior do espaço, encontrando uma concordância perfeita. / The aim of this thesis is to review Wilson loop operators in the contexto f the AdS/CFT correspondence. These operators, wich are present in any gauge theory, are important because they furnish an order parameter for confinement/deconfinement phase transitions. Besides this, they are particularly relevant in the study of the AdS/CFT correspondence because: i) they allow, in some cases, for exact results thanks to localization to matrix models and make it possible to perform highly non-trivial tests of the correspondence; ii) they are the gauge theory objects dual to strings propagating in the bulk of the space and give a rich dictionary between bulk (AdS) and boundary (CFT) quantities. After reviews of Wilson loops in gauge theories and of the Ads/CFT correspondence, we will introduce the definition of 1/2 BPS supersymmetric Wilson loops, we will compute them at weak coupling and then at any order in the coupling constant via matrix model techniques, and finally we will compare our results with minimal surface computations in the bulk, finding perfect agreement.

As a classical scholar and prominent founding father, James Wilson was at once statesman, judge, and political thinker, who read Cicero as an example worthy of emulation and as a philosopher whose theory could be applied to his own age. Classical reception studies have focused on questions of liberty, civic virtue, and constitutionalism in the American founding, and historians have also noted Wilson’s importance in American history and thought. Wilson’s direct engagement with Cicero’s works, however, and their significance in the formulation of his own philosophy has been long overlooked. My thesis argues that Wilson’s viewpoint was largely based on his readings of Cicero and can only be properly understood within this context. In the first two chapters of my thesis I demonstrate that Wilson not only possessed a wide-ranging knowledge of the classics in general, but also that he borrowed from Cicero’s writings and directly engaged with the texts themselves. Building upon this foundation, chapters three and four examine Cicero’s perspective on popular sovereignty and civic virtue, situate Wilson’s interpretations within contemporary discussions of Roman politics, and analyse the main ways in which he adapts Cicero’s arguments to his own era. Wilson retains a broader faith in the common people than seen in Cicero’s opinions, and he abstracts from Cicero a doctrine of sovereignty as an indivisible principle that is absent in the text; nevertheless, Cicero’s conception of a legitimate state and his insistence on the role of the people provided the foundation for Wilson’s thought and ultimately for his legitimization of the American Revolution. At the same time, like Cicero, Wilson views the stability of the state as resting in the personal virtue of the individual. While his enlightenment philosophy imparts optimism to his conception of the good citizen, his definition of virtue closely follows that of Cicero. As the final chapter of my thesis concludes, their individual interpretations of these theories of popular consent and virtue were instrumental in forming Cicero’s and Wilson’s justifications of civil disobedience.

My dissertation, “Africans, Cherokees, and the ABCFM Missionaries in the Nineteenth Century: An Unusual Story of Redemption,” assesses the experience of American missionaries in the Cherokee nation and in Western Africa during the nineteenth century. The American Board of Commissioners for Foreign Missions (ABCFM), founded in 1810, was the first successful foreign missionary society in the U.S., and its campaign among the Cherokees served as springboard for its activities in “Western Africa”—Liberia, Ivory Coast, Gabon, and South Africa. Although the Cherokees and the West Africans were two different peoples, the ABCFM used the same method to Christianize them: the Lancasterian method with which the missionaries planned to “civilize” the Cherokees and West Africans before Christianizing them. Scholars such as William McLoughlin and Theda Purdue studied the missionary perspective and the Cherokee perspective as separate entities and convincingly maintained that the Cherokees embraced the ABCFM’s civilization and Christianization program partly to relieve the pressures on their lands and partly to adapt to the cultural pressures of their times. However, as my dissertation argues, the conversion story of the Cherokees takes a different turn if told simultaneously from the missionary and the Cherokee perspectives. Regarding the West African experience, authors such as Lamin Sanneh and Richard Gray have recently exposed the missionary and African sides of the stories with new questions that had been waiting to be asked for a long time. My dissertation, taking a unique comparative perspective, reveals first that West Africans did not face the same pressures as those faced by the Cherokees, yet, they still embraced the ABCFM’s civilization and Christianization program, though with a lesser sense of urgency and with more assertiveness than did the Cherokees despite the white missionaries’ racism. More importantly, by way of a method I call parallel agency, my dissertation offers a revisionist interpretation of the history of missions, which has traditionally emphasized the power of the white missionaries by calling into question the very assumption that the white missionaries had significantly more power than did their Cherokee and African converts.

Ce travail de thèse a consisté à synthétiser de nouveaux chélateurs pour la complexation des ions métalliques d10 toxiques en milieu biologique, comme le cuivre (I), lorsqu'il est présent en excès dans les cellules, et le mercure (II), délétère à l'état de traces. En particulier, des tripodes à trois soufres, inspirés de tripodes fonctionnalisés par trois dérivés cystéine, développés antérieurement au laboratoire, ont été élaborés et leur propriétés de complexation avec le cuivre (I) ont été examinées. Comme les tripodes cystéines, les nouveaux tripodes fonctionnalisés par d'autres dérivés soufrés, en particulier des dérivés de D-Pénicillamine (D-PEN), sont capables de complexer le cuivre (I) dans des environnements CuS3 avec de fortes affinités et sélectivités par rapport au zinc (II) présent dans les milieux biologiques. Des études structurales approfondies effectuées par spectroscopie d'absorption des rayons X (XAS) ont permis de caractériser complètement les complexes et clusters de cuivre (I) formés, de corréler les mesures d'affinités effectuées en utilisant différentes techniques et de rationaliser les relations structure/ affinité observées. L'un des nouveaux tripodes a ensuite été fonctionnalisé pour être ciblé vers les cellules du foie, où une accumulation de cuivre est observée chez les patients atteints de la maladie de Wilson. Les premiers tests biologiques réalisés sur des cellules hépatiques ont montré que l'architecture fonctionnalisée ainsi conçue (CHEL4) est capable de complexer le cuivre (I) en excès in cellulo. Cette étude conforte les résultats obtenus antérieurement au laboratoire avec le tripode cystéine fonctionnalisé (CHEL2) et valide donc le système de vectorisation vers les hépatocytes. Les propriétés de complexation des nouveaux tripodes avec l'ion toxique mercure (II), plus gros et plus mou que l'ion cuivre (I), ont aussi été étudiées. Il a ainsi été établi que les nouveaux tripodes thiolates peuvent aussi stabiliser un environnement trigonal autour du mercure (II). Notre étude a donc montré comment des tripodes soufrés de faible poids moléculaire, judicieusement fonctionnalisés, peuvent accommoder des environnements trigonaux très stables autour des ions mous cuivre (I) et mercure (II). De tels environnements miment plus ou moins les sites trigonaux du cuivre (I) et du mercure (II) trouvés dans les protéines à cuivre (I) (Ctr1, Mac1, Ace 1, COX…), les protéines bactériennes de détoxification du mercure (II) (Mer-R), et les métallothionéines (MTs), petites protéines riches en cystéines qui complexent les ions métalliques en excès ou toxiques dans les cellules. Ces analogies avec les complexes métalliques biologiques permettent de rationnaliser les fortes affinités des nouveaux tripodes pour les ions mous cuivre (I) et mercure (II). Plus généralement, notre étude apporte des règles de design moléculaires pour concevoir des architectures efficaces dédiées à la détoxification des métaux mous en milieu biologiques. Mots clés : cuivre (I), zinc (II), mercure (II), maladie de Wilson, foie, surcharges métalliques, toxicité, chélateurs, tripodes soufrés, cystéine, D-pénicillamine (D-PEN), environnements trigonaux, protéines du cuivre (I), métallothionéines (MTs), Mer-R, Spectroscopie d'Absorption des rayons X (XAS). / This work consisted in the syntheses of new chelators for the binding of soft d10 metal ions in biological media, such as the copper (I) ion, toxic at high levels in the cells, and the mercury (II) ion, deleterious even at low concentrations. In particular, new suphur-based tripodal architectures, derived from the cysteine-based architectures previously designed at the laboratory, have been synthetized and their binding properties with the copper (I) ion have been looked into. As the cysteine-based scaffolds, the new chelators, based on new sulphur compounds, in particular D-Penicillamine (D-PEN) derivatives, complex the copper (I) ion in trigonal CuS3 environments with high affinities and high selectivities with respect to the bioavailable zinc (II) ion. In depth structural studies have been performed by X-Ray Absorption Spectroscopy (XAS) to fully characterize the copper (I) complexes and the copper (I) clusters formed in solution, to correlate the affinity measurements performed using different analytical techniques and to rationalize structure/ affinity relationships. One of the new chelators has been functionalized to be targeted to the liver cells, where copper (I) overloads are observed when people suffer from the Wilson's disease. The first biological experiments carried out in hepatocytes, have shown that the functionalized chelator (CHEL4) complexes excess copper (I) in cellulo. This study supports the results previously obtained with the functionalized cysteine-based architecture (CHEL2) and thus validates the targeting system. The binding properties of the new tripodal architectures with the mercury (II) ion, bulkier and softer than the copper (I) ion, have also been studied. It has been established that the new chelators also stabilize trigonal environments around the mercury (II) ion. Thus this study has shown how low molecular weight sulphur-based tripodal architectures, judiciously functionalized, are able to adapt stable sulphur-only trigonal environments around the soft metal ions, copper (I) and mercury (II). Such environments reproduce more or less the trigonal binding sites found in copper (I) proteins (Crt1, Mac1, Ace1, COX…), bacteria proteins dedicated to mercury (II) detoxification (Mer-R) and metallothioneins (MTs), which are small cysteine-rich proteins in charge of the detoxification of toxic metal ions in cells. Those structural analogies shared with the biological metallic complexes allow us to rationalize the high affinities of the new tripodal architectures for soft metal ions. In a more extended point of view, this study brings some guidelines of molecular design to elaborate efficient chelators dedicated to the detoxification of soft metal ion in biological media. Keywords: copper (I), zinc (II), mercury (II), Wilson's disease, liver, metal overloads, toxicity, chelators, sulphur-based tripods, cysteine, D-penicillamine (D-PEN), trigonal environments, copper (I) proteins, metallothioneins, Mer-R, X-Ray Absorption Spectroscopy (XAS).

In a single capture-recapture problem, two new Wilson methods for interval estimation of population size are derived. Classical Chapman interval, Wilson and Wilson-cc intervals are examined and compared in terms of their expected interval width and exact coverage properties in two models. The new approach performs better than the Chapman in each model. Bayesian analysis also gives a different way to estimate population size.
