In 1913, the Industrial Workers of the World (IWW) led a strike of silk workers in Paterson, New Jersey. Several New York intellectuals took advantage of Paterson's proximity to New York to witness and participate in the strike, eventually organizing the Paterson Pageant as a fundraiser to support the strikers. Directed by John Reed, the strikers told their own story in the dramatic form of the Pageant. The IWW and the Paterson Silk Strike inspired several writers to relate their experience of the strike and their participation in the Pageant in fictional works. Since labor and working-class experience is rarely a literary subject, the assertiveness of workers during a strike is portrayed as a catastrophic event that is difficult for middle-class writers to describe. The IWW's goal was a revolutionary restructuring of society into a worker-run co-operative and the strike was its chief weapon in achieving this end. Inspired by such a drastic challenge to the social order, writers use traditional social organizations--religion, nationality, and family--to structure their characters' or narrators' experience of the strike; but the strike also forces characters and narrators to re-examine these traditional institutions in regard to the class struggle. / English

Within the accepted historiography of photography, the importance of George Eastman and the Eastman Kodak Company (EKC) has become unassailable. They have been placed as the key, and often sole, agent in “revolutionizing” the amateur photography market in the late nineteenth century. While the photographic landscape and market of 1885-1914 was indeed radically altered, the historiographical dominance of what can be identified as the “Kodak story” has obscured the means through which EKC’s successful re-structuring of the existing manufacturing and distribution networks of photographic materials occurred. I argue that the changes effected by Eastman and the EKC began not with imaging desires, but with their acknowledgment, and profound understanding of the existing and competing interests within the photographic industry. This thesis focuses on the EKC’s re-structuring of the extant and evolving communities involved in the manufacturing and distribution of photographic materials in Canada between 1885-1910. Focusing particularly on the period immediately surrounding the establishment of the Canadian Kodak Co. Limited in 1899, I demonstrate the re-structuring processes at work, including: market and financial diversification; governmental lobbying; purchase and mergers; and other business and marketing-based strategies. I frame my theoretical positions and analysis of network re-structuring through the experiences of Ottawa professional photographer and photographic business owner William James Topley (active 1868-1907), and CKCoLtd manager John Garrison Palmer (active 1886-1921). Topley and Garrison’s professional experiences and interactions with expanded communities of photographic consumers and industry participants provide an opportunity for specific and detailed findings which challenge understandings of the evolution of the practice of photography during this transitional period. In doing so, I provide evidence of the primary role network re-structuring played in the EKC’s ability to shape the wider international photographic industry to their advantage in the early twentieth century.

This presentation tells the story of two partnerships co-initiated by the ETSU Center of Excellence in Mathematics and Science Education. The first partnership, Eastman Scholar MathElites, demonstrates how a 7+ year partnership between business and an institute of higher education (Eastman-ETSU) has brought a regional impact in Grades 3-8 math. The second partnership, G6-12 Science and Literacy project, introduces how a local education agency and institute of higher education (Hawkins County Schools-ETSU) have worked together to provide teacher professional development (PD) that focuses on Grades 6-12 English Language Arts and Science. This PD seeks to build confidence and understanding about using reading as a tool to understand STEM literacies. These two programs do not only benefit K-12 education in the Northeast Tennessee region, but also bring practical implications for future development in state-wide and national issues.

The objective of this thesis is to present a study of the political impact of Communism on four individuals who at one stage in their lives thought that Communism was the best political system on earth, and who subsequently became disillusioned ot the point where they considered Communism the worst political system on earth. This thesis tries to answer some of the questions arising from such a study. How did these four people become so enamoured of Communism and later so thoroughly disillusioned with it? What is there about Communism which could so strongly attract and later so thoroughly repel intelligent people? Was disaffection due to the weakness of the people involved, or was it due to weaknesses in the Communist system? Where is the truth to be found regarding the essential nature of Communism: in the official reports and propaganda of the Russian government, or in the opinions of the Communist Party members, or in the writings of those who have been in close contact with the system? The problem is to determine the nature of the attraction of Communism and the nature of its repellent aspects as seen by four of those who have strongly felt, in turn, that attraction and that repulsion.

In conclusion: Data of the 2 populations of athletes showed that there is a great variance on the oral health among the evaluated individuals. Several conditions that might have a potencial influence on the performance of the athletes were detected with the aid of digital panoramic radiographs, and this suggests that an oral health program should be included as part of the preparation of those individuals.

[pt] A indústria 4.0 impulsionou o desenvolvimento de novas tecnologias para atender as demandas atuais do mercado. Uma dessas novas tecnologias foi a incorporação de técnicas de inteligência computacional no cotidiano da indústria química. Neste âmbito, este trabalho avaliou o desempenho de controladores baseados em aprendizado por reforço em processos químicos industriais. A estratégia de controle interfere diretamente na segurança e no custo do processo. Quanto melhor for o desempenho dessa estrategia, menor será a produção de efluentes e o consumo de insumos e energia. Os algoritmos de aprendizado por reforço apresentaram excelentes resultados para o primeiro estudo de caso, o reator CSTR com a cinética de Van de Vusse. Entretanto, para implementação destes algoritmos na planta química do Tennessee Eastman Process mostrou-se que mais estudos são necessários. A fraca ou inexistente propriedade Markov, a alta dimensionalidade e as peculiaridades da planta foram fatores dificultadores para os controladores desenvolvidos obterem resultados satisfatórios. Foram avaliados para o estudo de caso 1, os algoritmos Q-Learning, Actor Critic TD, DQL, DDPG, SAC e TD3, e para o estudo de caso 2 foram avaliados os algoritmos CMA-ES, TRPO, PPO, DDPG, SAC e TD3. / [en] Industry 4.0 boosted the development of new technologies to meet current market demands. One of these new technologies was the incorporation of computational intelligence techniques into the daily life of the chemical industry. In this context, this present work evaluated the performance of controllers based on reinforcement learning in industrial chemical processes. The control strategy directly affects the safety and cost of the process. The better the performance of this strategy, the lower will be the production of effluents and the consumption of input and energy. The reinforcement learning algorithms showed excellent results for the first case study, the Van de Vusse s reactor. However, to implement these algorithms in the Tennessee Eastman Process chemical plant it was shown that more studies are needed. The weak Markov property, the high dimensionality and peculiarities of the plant were factors that made it difficult for the developed controllers to obtain satisfactory results. For case study 1, the algorithms Q-Learning, Actor Critic TD, DQL, DDPG, SAC and TD3 were evaluated, and for case study 2 the algorithms CMA-ES, TRPO, PPO, DDPG, SAC and TD3 were evaluated.

Hot water discharges and potential chemical spills are factors that threaten water quality in cooling reservoirs of chemical and power plants. In this thesis, three models are used to analyze the impact of these factors in a particular case study.

Les liquides complexes sont des matériaux très prometteurs pour réaliser la conversion bon marché et à grande échelle d’énergie thermique en énergie électrique, dans un contexte de réchauffement climatique et de maîtrise de la consommation d’énergie. Nous montrons qu’en présence d’un couple redox, les cellules thermogalvaniques à base de liquides ioniques (NEA et EMIMTFSI) présentent des propriétés remarquables tels des coefficients Seebeck de plus de 5 mV/K (Eu³⁺/Eu²⁺ dans l’EMIMTFSI). De même, ces travaux présentent l’utilisation de ferrofluides, solutions colloïdales (aqueuses ou à base de solvants organiques) de nanoparticules magnétiques (maghémite), pour accroître le coefficient Seebeck et le courant extractible de générateurs thermoélectriques liquides. Les phénomènes réversibles d’adsorption des nanoparticules sur la surface des électrodes jouent également un rôle important sur les propriétés thermoélectriques de ces solutions, et sont modifiés par l’application de champs magnétiques homogènes parallèles ou perpendiculaires au gradient de température.En l’absence d’un couple redox, les liquides ioniques peuvent être utilisés pour fabriquer des supercondensateurs à charge thermique. Ces derniers exploitent les modifications avec la température des double couches électriques aux interfaces liquide/électrode. Nous avons étudié ici ces modifications de double couches dans l’EMIMBF4 par simulations numériques de Monte-Carlo. Les résultats démontrent un accroissement conséquent des propriétés thermoélectriques lors de la dilution du liquide ionique dans un solvant organique, l’acétonitrile, en accord qualitatif avec les résultats expérimentaux. / Complex liquids are promising material for low cost and wide scale conversion of thermal energy to electric energy, within a context of global warming and control of the energy consumption.In this work we showed that with a redox couple, ionic liquid (EAN and EMIMTFSI) based thermogalvanic cells present remarkable thermoelectric properties such as the Seebeck coefficient over 5 mV/K (Eu³⁺/Eu²⁺ in EMIMTFSI). Moreover, we demonstrated for the first time that ferrofluids, colloidal solutions (aqueous or organic solvent based) of magnetic nanoparticles (maghemite), can be used to increase both the Seebeck coefficient and the electric current in liquid thermoelectric generators through unknown physical processes. The importance of reversible adsorption phenomena of the nanoparticles on the electrodes’ surface for the thermoelectric properties of these solutions was revealed. That can be further modified by a homogeneous magnetic field applied perpendicular or parallel to the temperature gradient. Without a redox couple, ionic liquids can be used to build thermally chargeable supercapacitors. They take advantage of temperature dependent electrical double-layer formation at liquid/electrode interfaces. Here, we studied these double-layer modifications in EMIMBF4/platinum through Monte-Carlo simulations. The results show substantial modifications in the thermoelectric properties when the ionic liquid is diluted in an organic solvent, acetonitrile. These results are qualitatively consistent with experimental measurements.
