Disabilities of Fiction: Reading Madness in Twentieth-Century American Women's Literature

Peterson, Erica Lyn 05 1900 (has links)
In this dissertation, disability theories frame readings of madness in select works by Shirley Jackson, Sylvia Plath, and Toni Cade Bambara. The dissertation explores the relationship between madness and fiction, with the author demonstrating the productive and generative aspects of madness. Close readings of the literary works emphasize the impact of madness on structural and formal elements including narrative perspective, sustained metaphors, and narrative time. In chapter one, I use the disability theory concepts of narrative prosthesis and aesthetic nervousness to read Jackson's The Haunting of Hill House. In chapter 2, I analyze Jackson's We Have Always Lived in the Castle to explore the concept of unreliable narration, observing similarities between the social model of disability and reader-centric theories of unreliable narration. In chapter 3, I explore unhealthy disability and medical treatment in the sustained metaphors of light and darkness in Plath's hospital stories, "Tongues of Stone," "Johnny Panic and the Bible of Dreams," and "The Daughters of Blossom Street." In chapter 4, I use disability history to read narratives of medical institutionalization in Plath's novel The Bell Jar. In chapter 5, I use Bambara's concept of "other kinds of intelligences" to develop a Black feminist methodology for reading mad intelligences in Bambara's novel The Salt Eaters. In the dissertation's conclusion, I note prejudice against madpersons in recent legal policies promoting involuntary psychiatric institutionalization, using Bambara's short story "The Hammer Man" to demonstrate the violence of such policies.

Zavedení systému řízení bezpečnosti u malého leteckého dopravce / Implementation of the Safety Control of Small Aircraft Operator

Šalanda, Michal January 2008 (has links)
Nowadays preservation of safety is one of the most important conditions for consequential air traffic development. That was the reason why the Safety Management System was formed by the ICAO. Thesis´ objective was especially to scrutinize all the aspects relating to implementation of this system. In the first place every component of the system was described, eventually its function. Next point was to draft an implementation plan for small aviation operators. Besides that ways and means of evaluating effectiveness of the system and expected benefits were described. The process of implementation was consulted with several aviation operators and organizations related to civil aviation whether from the Czech Republic or abroad. Their knowledge helped in many ways to make an issue of practical implementation of the Safety Management System clear. Finally it is true to say that the Safety Management System going to be an essential part of every aviation operator in few years.

Avaliação de diversos métodos de detecção de cistos de Giardia spp. e Oocistos de Cryptosporidium parvum presentes no resíduo gerado após o tratamento de água de abastecimento com turbidez elevada / Evaluation of several methods for the detection of Giardia spp. cysts and Cryptosporidium parvum Oocysts in wastes produced after high- turbidity water treatment

Este trabalho teve como objetivo avaliar diversos métodos de detecção e recuperação de cistos de Giardia spp. e de oocistos de Cryptosporidium parvum em resíduos gerados no tratamento de águas de abastecimento com turbidez elevada tendo como padrão o Método 1623.1 da USEPA (2012 ). Para tanto, ensaios utilizando aparelho Jarteste (coagulação, floculação, decantação e filtração ) foram realizados utilizando o coagulante cloreto de polialumínio - PAC. Em todos os métodos avaliados foi utilizada a técnica de purificação por separação imunomagnética - IMS. A adaptação do método floculação em carbonato de cálcio FCCa elaborado por Vesey et al. (1993) e adaptado por Feng et al. (2011), repercutiu nos melhores resultados para a amostra de resíduo sedimentado, com recuperações de 68 ± 17 % para oocisto de C. parvum e de 42 ± 7 % para cisto de Giardia spp. Entretanto, as recuperações para a amostra de água de lavagem dos filtros - ALF foram inferiores à 1 %, não sendo possível determinar um método adequado. A presença dos patógenos indica que o reuso da ALF em ETA convencionais ou o descarte em mananciais sem um tratamento prévio, pode representar problemas de contaminação. A adaptação dos métodos de Boni de Oliveira (2012) e Keegan et al. (2008), também repercutiram em porcentagens de recuperação expressivas para a amostra de resíduo sedimentado, sendo de: 41 ± 35 % para oocisto de C. parvum e 11 ± 70 % para cisto de Giardia spp., e 38 ± 26 % para oocisto de C. parvum e 26 ± 13 % para cisto de Giardia spp., respectivamente. A análise estatística não resultou em diferença significativa entre estes dois métodos, entretanto, as elevadas recuperações indicam que estes métodos podem ser melhor avaliados em pesquisas futuras. / This dissertation addresses the evaluation of several methods for the detection of Giardia spp. cysts and Cryptosporidium parvum oocysts in wastes produced after a high-turbidity water treatment, according to Method 1623.1 from USEPA (2012). Coagulant polyaluminium chloride - PACl was used in jar test experiments (coagulation/flocculation, sedimentation and filtration ). The Immunomagnetic Separation - IMS technique was applied to all methods. The calcium carbonate flocculation (CCF) method, developed by Vesey et al. (1993) and adapted by Feng et al. (2011 ), was applied to sludge samples in this research and was the best method tested, with 68% ± 17 % and 42 % ± 7,00 % recoveries for C. parvum oocysts and Giardia spp. cysts, respectively. On the other hand, the percentage recovery of (oo)cysts for filter backwash water samples was lower than 1 % and no suitable method could be detected. The presence of pathogens represents contamination risks for water sources and the reuse of filter backwash water may be a problem to conventional water treatment plants. The application of Boni de Oliveira (2012) and Keegan et al. (2008) methods, adjusted to this study, also resulted in significant percentage recoveries for the sludge samples, with 41 ± 35 % for C. parvum oocyst and 11 ± 70% for cyst Giardia spp., and 38 ± 26% for oocyst C. parvum and 26 ± 13% for cyst Giardia spp., respectively. The statistical analysis showed no significant differences between the two methods, however, such high recoveries indicate they should be better evaluated in future research.

Blízkovýchodní aliance: analýza vztahů a dalšího vývoje regionu / The Middle Eastern alliances: Analysis of relations and further development of the region

Eštoková, Denisa January 2015 (has links)
Examining any topic in the Middle East requires a general knowledge because of the region's complexity and dynamics. Important characteristics is the link of Islam and politics, because this relation shaped political establishment of states. The strategic location and rich natural resources of this part of the world were tempting also for the global superpowers whose engagement divided the Middle Eastern states, particularly during the Cold War. An analysis of the factors and events that led to the formation of alliances and rivalries in the Middle East is the goal of this work. Research will focus on alliances of Iran and its Shia allies on the one hand and Saudi Arabia with the rest of Sunni monarchies on the other. Unlike other alliances mentioned in the work, these two blocks have long term character. They are also specific because of sectarian differences, their stance towards the United States and Israel and shared responses to emerging threats. Historical development of Middle Eastern alliances begins with the dissolution of the Ottoman Empire, continues with the both World wars, the Israeli-Arab conflict, the Islamic revolution in Iran and other milestones which were meaningful in shaping inter-state relations in the region. The modern period moves from invasions of Afghanistan and Iraq to...

A Comparison Of Aluminum And Iron-based Coagulants For Treatment Of Surface Water In Sarasota County, Florida

Yonge, David 01 January 2012 (has links)
In this research, five different coagulants were evaluated to determine their effectiveness at removing turbidity, color and dissolved organic carbon (DOC) from a surface water in Sarasota County, Florida. Bench-scale jar tests that simulated conventional coagulation, flocculation, and sedimentation processes were used. Iron-based coagulants (ferric chloride and ferric sulfate) and aluminum-based coagulants (aluminum sulfate, polyaluminum chloride (PACl) and aluminum chlorohydrate (ACH)) were used to treat a highly organic surface water supply (DOC ranging between 10 and 30 mg/L), known as the Cow Pen Slough, located within central Sarasota County, Florida. Isopleths depicting DOC and color removal efficiencies as a function of both pH and coagulant dose were developed and evaluated. Ferric chloride and ACH were observed to obtain the highest DOC (85% and 70%, respectively) and color (98% and 97%, respectively) removals at the lowest dose concentrations (120 mg/L and 100 mg/L, respectively). Ferric sulfate was effective at DOC removal but required a higher concentration of coagulant and was the least effective coagulant at removing color. The traditional iron-based coagulants and alum had low turbidity removals and they were often observed to add turbidity to the water. PACl and ACH had similar percent removals for color and turbidity achieving consistent percent removals of 95% and 45%, respectively, but PACl was less effective than ACH at removing organics. Sludge settling curves, dose-sludge production ratios, and settling velocities were determined at optimum DOC removal conditions for each coagulant. Ferric chloride was found to have the highest sludge settling rate but also produced the largest sludge quantities. Total trihalomethane formation potential (THMFP) was measured iv for the water treated with ferric chloride and ACH. As with DOC removal, ferric chloride yielded a higher percent reduction with respect to THMFP.
