Representations of Solitary Confinement in Four Ontario Penal History Museums

Jarvis, Amelia 11 January 2019 (has links)
This thesis examines representations of solitary confinement at four penal history museums in the province of Ontario, Canada: the Olde Gaol Museum in Lindsay, the L’Orignal Old Jail in L’Orignal, the Peel Art Gallery Museum and Archives in Brampton, and Kingston Penitentiary in Kingston. Engaging with Brown’s (2009) theory of “penal spectatorship” and Cohen’s (2001) work on states of denial, I investigate how these representations of solitary confinement challenge and/or reinforce the idea that segregation is a necessary practice in operational carceral institutions. I identify three dominant themes. The first theme is who ends up in solitary confinement and why. The museums justify the necessity of solitary confinement by emphasizing its usefulness in neutralizing dangerous and unpredictable prisoners, along with its supposed ability to promote prisoner protection and the management of mental health needs. The second theme pertains to the duration prisoners spend in solitary confinement and the conditions they experience. The museums do not problematize prisoners’ length of stay in solitary confinement, nor the conditions of the cells in which they are held, rather historical penal discourses are used to demonstrate improvements over time, without problematizing its present uses. The third theme arising from my analysis concerns the impacts of solitary confinement on prisoners. The museums emphasize the positive effects that solitary confinement can have on prisoners such as providing the opportunity for contemplation, while information on the negative effects of isolation including exacerbating or triggering mental health issues are largely absent. Taking these findings into consideration, I argue that the penal history museums I examined foster social distance between visitors and those in conflict with the law by legitimating the exclusion of the latter, while reinforcing the idea that solitary confinement is a necessary practice in carceral institutions today. .

Dynamic studies of nano-confined polymer thin films

Geng, Kun 05 March 2017 (has links)
Polymer thin films with the film thickness (h0) below ~ 100 nm often exhibit physical properties different from the bulk counterparts. In order to make the best use of polymer thin films in applications, it is important to understand the physical origins of these deviations. In this dissertation, I will investigate how different factors influence dynamic properties of polymer thin films upon nano-confinement, including glass transition temperature (Tg), effective viscosity (ηeff) and self-diffusion coefficient (D). The first part of this dissertation concerns the impacts of the molecular weight (MW) and tacticity on the Tg’s of nano-confined polymer films. Previous experiments showed that the Tg of polymer films could be depressed or increased as h0 decreases. While these observations are usually attributed to the effects of the interfaces, some experiments suggested that MW’s and tacticities might also play a role. To understand the effects of these factors, the Tg’s of silica-based poly(α-methyl styrene) (PαMS/SiOx) and poly(methyl methacrylate) (PMMA/SiOx) thin films were studied, and the results suggested that MW’s and tacticities influence Tg in nontrivial ways. The second part concerns an effort to resolve the long-standing controversy about the correlation between different dynamics of polymer thin films upon nano-confinement. Firstly, I discuss the experimental results of Tg, D and ηeff of poly(isobutyl methacrylate) films supported by silica (PiBMA/SiOx). Both Tg and D were found to be independent of h0, but ηeff decreased with decreasing h0. Since both D and ηeff describe transport phenomena known to depend on the local friction coefficient or equivalently the local viscosity, it is questionable why D and ηeff displayed seemingly inconsistent h0 dependencies. We envisage the different h0 dependencies to be caused by Tg, D and ηeff being different functions of the local Tg’s (Tg,i) or viscosities (ηi). By assuming a three-layer model, we were able to account for the experimental data and resolve the inconsistency. By extending the same ideas to the analogous data of silica-based polystyrene films (PS/SiOx), we found a resolution to the inconsistency regarding the effects of nano-confinement on the dynamics of polymer thin films.

No. of bitstreams: 1 HeliaMSL_TESE.pdf: 1102082 bytes, checksum: 960a39ace6d2fbbcba482fe77e6ee546 (MD5) Previous issue date: 2017-09-25 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The objective of the study was to evaluate the effect of different proportions of high-level diets on finishing lambs in feedlot system on performance. However, there is no ingestive and physiological behavior, as well as carcass characteristics, quality physical and chemical characteristics of meat and production costs. For this purpose, whole corn grain associated with the protein-mineral-vitamin supplement was used in three proportions of concentrate: bulky (100%, 80:20 and 60:40%), a concentrated portion of the diet composed of 85 % of whole corn grain and 15% of supplement and bulky portion of Tifton hay). Twentyfour non-castrated males with no defined racial pattern were used with initial weight of 20.9 ± 1.0 kg at the age of 6 months. Weight gain was achieved in the three diets tested from 0.302g / day for 100% diet, 0.254g / day to 80:20 and 0.259g / day for 60:40 Minor rumination time (P≤0.05) in lambs of the treatment based on grain 100% when compared to the lambs of the other treatments. The 100% diet presented higher feed efficiency (EAL) and also more efficient rumination (ERU). Evaluating a temperature of the rumen region, it can be seen that the animals that received a 100% diet showed the variation of the temperature of the reen region, as 80:20 and 60: 40% diets affect nearby temperatures. As evaluated diets contributed to the performance with satisfactory gains, although preferences of use of diet of high grade, these guarantee like basic actions. There was a significant effect on carcass yield. A 100% concentrated diet showed a carcass yield of 47%, while for 80: 20% and 60: 40% diets obtained carcass yield values of 43.5% and 43.4%, respectively. The gastrointestinal content also had an effect, being lower in treatments 100% and 80: 20%. (P> 0.05) in the variables pH, temperature, color, water retention capacity and shear force. The 100% treatment presented a weight loss in cooking as well as superior thiobarbituric acid (TBARS) when compared with other diets. The 100% diet, when compared with other diets, obtained an additional carcass weight of 2.30 kg per animal. The use of the 100% concentrated diet in lamb termination systems is a more viable alternative from a productive and economical point of view / RESUMO: Objetivou-se com o estudo avaliar o efeito de diferentes proporções de dietas de alto grão na terminação de cordeiros em sistema de confinamento sobre o desempenho e alterações no comportamento ingestivo e fisiológico, assim como as características de carcaça, qualidade físicas e químicas da carne e custos de produção. Utilizou-se para tal, grão de milho inteiro associando ao suplemento protéico-mineral-vitamínico em três proporções de concentrado:volumoso, (100%, 80:20% e 60:40%), sendo a porção concentrada da dieta composta de 85% de grão de milho inteiro e 15% de suplemento e a porção volumosa de feno de Tifton). Foram utilizados 24 machos não castrados, sem padrão racial definido com peso inicial de 20,9 ± 1,0kg com idade de 6 meses. Conseguiu-se obter ganhos de peso nas três dietas testadas de 0,302g/dia para dieta 100%, 0,254 g/dia para 80:20 e 0,259 g/dia para 60:40 O tempo de ruminação foi menor (P≤0,05) nos cordeiros do tratamento à base de grão 100% quando comparados aos cordeiros dos demais tratamentos. A dieta 100% apresentou maior eficiência de alimentação (EAL) e também mais eficiente na ruminação (ERU). Avaliando a temperatura da região do rúmen percebe-se que os animais que receberam a dieta 100% apresentaram acentuada variação de temperatura da região do rémen, as dietas 80:20 e 60:40% apresentam alterações de temperaturas próximas. As dietas avaliadas contribuíram para o desempenho com ganhos satisfatórios, apesar de ocorrer alterações comportamentais com uso da dieta de alto grão, estas garantem as ações básicas necessária para manter a saúde ruminal adequada. Houve efeito significativo para rendimento de carcaça. A dieta 100% concentrado apresentou um rendimento de carcaça de 47%, enquanto as dietas 80:20% e 60:40% obtiveram valores para rendimento de carcaça de 43,5% e 43,4% respectivamente. O conteúdo gastrointestinal também apresentou efeito, sendo menor nos tratamentos 100% e 80:20%. Para os parâmetros físicos da carne, não foi observado diferenças significativa (P>0,05) nas variáveis pH, temperatura, cor, capacidade de retenção de água e força de cisalhamento. O tratamento 100% apresentou uma menor perda de peso na cocção assim como também apresentou ácido tiobarbitúrico (TBARS) superior quando comparado as demais dietas. A dieta 100%, quando comparado as demais dietas, obteve-se um peso adicional de carcaça de 2,30 Kg por animal. O uso da dieta 100% concentrado em sistemas de terminação de cordeiros é a alternativa mais viável do ponto de vista produtivo e econômico / 2018-01-31
