Gilbert Stuart completed the portrait of the new bride, Elizabeth Patterson Bonaparte, as well as portraits of 15 other women during his Washington period from late 1803 to early 1805. Scholars have often discounted this period in Stuart's work for its "compositional simplicity" and repeat choice of a stock white dress for the portraits of many of these women. But to dismiss this period is Stuart's work is to dismiss a period when Stuart positioned himself in the center of the "first circle" in Washington, a circle that included Dolley Madison and her most ambitious friends. Women, in this era after the American and French revolutions, had the freedom to enter into the public discourse. They were liberated from many of the more conservative principals of the early colonial period, shedding their restrictive clothing in the process. Stuart's salon, a highly visible public venue, as well as his ability to portray the strength of character and a direct, forthright gaze of the American woman, all made him extremely popular with women. Stuart, a critical force within the construction of a new image for this Nation, based on Jeffersonian ideas of republicanism, based his practice on simple, natural design influences. My goal is to more thoroughly examine Stuart's decisions in composing Betsy Bonaparte's portrait, as well as the facts surrounding her marriage to Napoleon Bonaparte's youngest brother. I will then consider why Elizabeth Bonaparte's wedding portrait represents the chef d'ouvre of his work during this period and how the young bride served as his muse, influencing his Washington style, and the women who followed her into the painter's studio. / text

The Tin dioxide (SnO2) and Titanium dioxide (TiO2) are very promising materials in Material science. The SnO2 is commonly used as a gas sensor while the TiO2 is used as a catalyst in many reactions. Despite of the usefulness of these two substances, their surface structures lack detail investigations in the previous years. The Low Energy Electron Diffraction (LEED) technique is commonly used to characterize surfaces in the past 40 years, it is a mature system that many researches rely on its result. However, structural analysis in LEED requires comparison with computational results based on pre-defined structure models, which is a time-consuming method and the results are not guaranteed to be found. The direct determinations of structure by Patterson function inversion methods introduced by Huasheng Wu and S. Y. Tong could provide a different path to search for surface structure. In the Patterson function, each maximum in the function corresponds to a relative position vector of atomic pairs. Multiple-angle-incident LEED has to be performed to obtain an artifact-free Patterson function. Serveal SnO2 and TiO2 surfaces have been characterized by LEED and Patterson function inversion. SnO2 (110), (100), (101) , Rutile TiO2 (110), Anatase TiO2 (110) have been prepared by argon ion sputtering and annealing cycles and the cleanness has been checked by Auger Electron Spectroscopy and LEED. Reconstruction is observed based on the study of the LEED patterns. SnO2 (110) surface shows a 4 x 1 reconstruction in UHV environment while it gives 1 x 1 under annealing in oxygen and C(2 x 2) at higher annealing temperature afterward. SnO2 (100) , (101) and Rutile TiO2 (110) surfaces show 1 x 1 reconstruction in UHV environment and the reconstruction persists for further annealing. The Anatase TiO2 (110) surface shows a 3 x 4 reconstruction in UHV environment. The 3 x 4 reconstruction of Anatase TiO2 (110) surface would raise research interests as it is quite a special reconstruction. Multiple-angle-incident LEED has been performed on the SnO2 (100), (101) and Rutile TiO2 (110) surfaces. Patterson function inversion is performed on the surfaces SnO2 (100) and Rutile TiO2 (110) . Only LEED is performed on SnO2 (110) , (101) and Anatase TiO2 (110) surfaces. From Patterson functions analysis, the surface atoms positions are determined for the surface SnO2 (100) and Rutile TiO2 (110). The results show that their reconstructions are negligible, but they have obvious relaxations. / published_or_final_version / Physics / Master / Master of Philosophy

In order to test the four stages of the model, it was realized a transversal study, considering three non-probabilistic samples, each one composed by approximately 100 students from public and private schools from Fortaleza – CE. Participants answered the Strenghts Difficulties Questionnaire (SDQ), Parenting Stile Inventory (PSI), Antisocial Conduct Questionnaire, Scale of Solitude, variables related to the academic performance and involvement with social deviant groups, as well as demographic questions. Depending on the sample, data were collected from teachers, parents, and students linked to the research institution. It is noteworthy that all ethical procedures were adopted to make the research possible. Data analyzes were performed using SPSS 19. Study 1 aimed to review the first stage of the Coercion Model and presented information about the predictive power of parental styles in relation to conduct problems in childhood. Study 2, which goal was to test the second stage of Coercion Model, pointed out that Conduct Problems were a predictor of social rejection and low academic performance. Study 3 aimed to test the third and fourth stages of the Model and its results partly supported Patterson’s theoretical proposal, once parenting styles (to the detriment of social rejection and low academic performance) presents as having the greatest predictive power in relation to association with deviants groups, which presents as an important predictor in explaining antisocial behaviors. Therefore, it is believed that the results obtained allowed to test the variables suggested by the Patterson’s Model in Brazilian context, contributing to the knowledge about the correlates of antisocial behavior. / O Modelo da Coerção, proposto por Patterson, apresenta algumas variáveis explicativas do desenvolvimento de comportamentos socialmente desviantes, a saber: treinamento básico em casa, rejeição social, fracasso escolar e adesão a grupos desviantes. Com o objetivo de se testar as quatro fases do modelo, foi realizado um estudo transversal, considerando três amostras de conveniência, compostas por aproximadamente 100 estudantes provenientes de escolas públicas ou privadas da cidade de Fortaleza-CE. Os participantes responderam ao Strenghts Difficulties Questionnaire (SDQ), ao Inventário de Estilos Parentais (IEP), ao Questionário de Conduta Antissocial (CCA), à Escala de Solidão, às variáveis relativas ao desempenho acadêmico e ao envolvimento com grupos de pares desviantes, além de perguntas de caráter sociobiodemográfico. A coleta dos dados ocorreu, variando de acordo com a amostra, com os professores, pais e alunos vinculados à instituição pesquisada. Ressalta-se que todos os procedimentos éticos foram adotados a fim de viabilizar a pesquisa. As análises dos dados foram realizadas pelo SPSS 19. O Estudo 1, que buscou a avaliar a primeira etapa do modelo, apresentou informações acerca do poder explicativo dos estilos parentais em relação aos problemas de conduta na infância. O Estudo 2, cujo objetivo foi testar a segunda fase do Modelo da Coerção, apontou que os problemas de conduta apresentam poder explicativo em relação à rejeição social e ao baixo desempenho acadêmico. O Estudo 3 teve como propósito testar a terceira e quarta fase do modelo, os resultados encontrados apoiaram, em parte, a proposta teórica de Patterson para essas fases, uma vez que a variável estilos parentais (em detrimento à rejeição social e o baixo desempenho acadêmico) se apresentou como a variável com maior poder explicativo em relação à associação com grupos desviantes que, por sua vez, apresentou-se como importante preditora na explicação dos comportamentos socialmente desviantes. Portanto, confia-se que os resultados alcançados permitiram testar as variáveis sugeridas pelo modelo de Patterson em contexto brasileiro, contribuindo para o conhecimento acerca dos correlatos do comportamento antissocial.

The purpose of this thesis was to gain an insight into the macrobotanical subsistence practices of Nancy Patterson Village and see how those practices fit in with the practices of the general Mesa Verde region by analyzing the burnt macrobotanical remains found in processed flotation samples. Previous work done at Nancy Patterson Village showed a shift in the faunal subsistence practices to a greater reliance on domesticated turkey during the Pueblo III period. However, the macro botanical analysis showed a higher richness of wild plant taxa in the Pueblo III period when compared to Pueblo II. The change to a higher richness of plant taxa in the later period is attributed to the changes in social and environmental climates causing difficulties in sustaining the population. These difficulties pushed the inhabitants to expand their selection of plant types used for food. Despite the higher richness of plant taxa in Pueblo III, other sites from the Central Mesa Verde region had higher richness. However, Nancy Patterson Village used the smaller number of wild plants types more intensely than the other sites from the region. No explanation was found to explain this difference.

This dissertation explores embodiments of citizenship in three historical pageants of 1913. As historical pageantry reached the height of its popularity in the early twentieth century, the form was criticized by those who felt it represented a limited understanding of community and citizenship. Historical pageants came to prominence at a time in the nation’s history when lynching plagued the south, women agitated for the right to vote, and labor unions organized to demand better working conditions. Popular historical pageants presented a history which ignored these pressing social issues and supported the status quo. As a result, while pageants gained popularity the form was taken up by groups seeking to use pageants for different political purposes. My dissertation interrogates embodiments of citizenship in Progressive Era pageantry through three case studies: W.E.B. Du Bois wrote and staged Star of Ethiopia, devoted to re-telling African-American history; John Reed organized members of the Industrial Workers of the World (IWW) for a performance of The Paterson Strike Pageant to aid laborers on strike; and Hazel MacKaye staged Allegory in support of women’s suffrage. While each pageant aimed to promote diversity, once each pageant’s historiography landed on live bodies, the gaps between what the pageant argued for and who the pageant simultaneously excluded were made visible. Allegory crafted an argument for white women’s suffrage by excluding recent immigrant and women of color; Du Bois sought to promote the African American middle class by denigrating the working classes; John Reed painted an image of the IWW as a fully united working class while ignoring the racial and ethnic differences that had led to tensions among the group. Despite their progressive intentions, once each pageant moved its political arguments on stage, the choices they made in performance belied their inclusive aspirations. / text

Creating a bicycle with a rideable geometry is more complicated than it may appear, with today’s mainstay designs having evolved through years of iteration. This slow evolution coupled with the bicycle’s intricate mechanical system has lead most builders to base their new geometries off of previous work rather than expand into new design spaces. This crutch can lead to slow bicycle iteration rates, often causing bicycles to all look about the same. To combat this, several bicycle design models have been created over the years, with each attempting to define a bicycle’s handling characteristics given its physical geometry. However, these models often analyze a single bicycle at a time, and as such, using them in an iterative design process can be cumbersome. This work seeks to improve an existing model used by the Cal Poly Mechanical Engineering department such that it can be used in a proactive, iterative fashion (as opposed to the reactive, single-design paradigm that it currently supports). This is accomplished by expanding the model’s inputs to include more bicycle components as well as differently sized riders. This augmented model is then incorporated into several search platforms ranging from a brute-force implementation to several variants using genetic algorithm concepts. These models allow the designer to specify a bicycle design search space as well as a set of riders upfront, from which the algorithms search out and find strong candidate designs to return to the user. This in turn reduces the overhead on the designer while also potentially discovering new bicycle designs which had not been considered previously viable. Finally, a front-end was created to make it easier for the user to access these algorithms and their results.

Cette thèse s'articule principalement autour de la théorie des codes et des fonctions booléennes liés à la cryptographie. Deux axes sont suivis : la première partie est dédiée à la non-linéarité des fonctions booléennes, alors que la deuxième partie présente des applications en cryptographie d'objets provenant de ces théories. Motivé par la conjecture de Patterson et Wiedemann, nous proposons une généralisation de la construction par réunions d'orbites suivant l'action d'un groupe, où la minimisât!on de l'amplitude spectrale se ramène à deux sous-problèmes que nous étudions : l'estimation de sommes de Gauss et l'estimation de sommes d'exponentielles incomplètes. Plusieurs conditions et pistes de résolution de la conjecture sont alors détaillées. Ce travail nous permet de construire a sympto tique ment des fonctions de non-linéarité plus élevée que la moyenne et nous obtenons de plus, suivant ce principe, un exemple de recollement quadratique hautement non-linéaire proche de la borne de Patterson et Wiedemann en dimension 15. Dans la deuxième partie, nous portons tout d'abord notre attention sur des protocoles cryptographiques dits à faibles ressources. Des fonctions booléennes résistantes à la cryptanalyse différentielle sont utilisées afin de protéger le protocole HB+ d'une attaque par le milieu. À partir d'un deuxième protocole basé sur un principe de bruitage, nous effectuons un parallèle avec la théorie du canal à jarretière de Wyner, ce qui permet d'accroître la sécurité. D'autre part, dans le cadre de l'authentification de données variables dans le temps, une adaptation du cryptosystème de McEliece est détaillée afin de contrôler l'accès aux fonctions de vérification.
