Neste trabalho, desenvolvemos um modelo de regressão Birnbaum-Saunders bivariado através do uso da distribuição Senh-Normal proposta por Rieck (1989). Este modelo de regressão pode ser utilizado para analisar logaritmos de tempos de vida de duas unidades correlacionadas, e gera marginais correspondentes aos modelos de regressão Birnbaum-Saunders univariados. Apresentamos um estudo de inferência e análise de diagnóstico para modelo de regressão Birnbaum-Saunders bivariado proposto. Em primeiro lugar, apresentamos os estimadores obtidos através do método dos momentos e de máxima verossimilhança, e a matriz de informação observada de Fisher. Além disso, discutimos testes de hipóteses com base na normalidade assintótica dos estimadores de máxima verossimilhança. Em segundo lugar, desenvolvemos um método de diagnóstico para o modelo de regressão Birnbaum- Saunders bivariado baseado na metodologia de Cook (1986). Finalmente, apresentamos alguns resultados de estudos de simulações e aplicações em dados reais / Abstract: The Birnbaum-Saunders regression model of Rieck and Nedelman (1991) has been extensively discussed by various authors with application in survival and reliability studies. In this work a bivariate Birnbaum-Saunders regression model is developed through the use of Sinh-Normal distribution proposed by Rieck (1989). This bivariate regression model can be used to analyze correlated log-time of two units, it bivariate regression model has its marginal as the Birnbaum- Saunders regression model. For the bivariate Birnbaum-Saunders regression model is discussed some of its properties, in the moment estimation, the maximum likelihood estimation and the observed Fisher information matrix. Hypothesis testing is performed by using the asymptotic normality of the maximum-likelihood estimators. Influence diagnostic methods are developed for this model based on the Cook¿s(1986) approach. Finally, the results of a simulation study as well as an application to a real data set are presented / Mestrado / Estatistica / Mestra em Estatística

A distribuição bivariada Birnbaum-Saunders (BS) foi apresentada apenas recentemente por Kundu et al. (2010) e algumas extensões já foram discutidas por Vilca et al. (2014) e Kundu et al. (2013). Eles propuseram uma distribuição BS bivariada com estrutura de dependência e estabeleceram várias propriedades atraentes. Este trabalho fornece extensões, univariada e bivariada, da distribuição BS. Estas extensões são baseadas na distribuição Gaussiana Inversa (IG) que é usada como uma distribuição de mistura no contexto de misturas de escala normal. As distribuições resultantes são distribuições absolutamente contínuas e muitas propriedades da distribuição BS são preservadas. Sob caso bivariado, as marginais e condicionais são do tipo Birnbaum-Saunders univariada. Para a obtenção da estimativa de máxima verossimilhança (EMV) é desenvolvido um algoritmo EM. Ilustramos os resultados obtidos com dados reais e simulados / Abstract: Several works have been done on the univariate Birnbaum-Saunders (BS) distribution and its extensions. The bivariate Birnbaum-Saunders (BS) distribution was presented only recently by Kundu et al. (2010) and some extensions have already been discussed by Vilca et al. (2014) and Kundu et al. (2013). They proposed a bivariate BS distribution with dependence structure and established several attractive properties. This work provides extensions, univariate and bivariate, of the BS distribution. These extensions are based on the Inverse Gaussian (IG) distribution that is used as a mixing distribution in the context of scale mixtures of normal. The resulting distributions are absolutely continuous distributions and many properties of the BS distribution are preserved. Under bivariate case, the marginals and conditionals are of type univariate Birnbaum-Saunders. For obtaining the maximum likelihood estimates (MLE) of the model parameters is developed an algorithm EM. We illustrate the obtained results with real and simulated dataset / Mestrado / Estatistica / Mestra em Estatística

DIMENSIONS OF PAIN OF A DYING PERSON IN CONTEXT OF LIFE AND WORK OF CICELY SAUNDERS Pavel Beránek, Special Education, Department of Special Education, Faculty of Special Education, 2010 The thesis aims at Cicely Saunders (1918-2005), the founder of the modern hospic movement, at her influence on the movement and at the ideas she introduced. The personality of the dying person, listening to him/her and perception of his/her needs are described as key-stones of her thinking. The needs are seen through the concept of total pain - physical, psychical, social and spiritual. Special attention is given to influence of Viktor Frankl. Key words: Cicely Saunders, hospice, total pain, dying

After the Haitian Revolution (1791–1804), under the leadership of freed Black American-born Prince Saunders, working in conjunction with formerly enslaved revolutionaries, invited some 13,000 free African-Americans to leave the United States to emigrate to world’s first Black republic of Haiti. This migration offered the possibility of economic freedom and a promise/redefinition of the boundaries of citizenship and equality in the Atlantic world. Part I, “Abolitionist Pioneers and Origins,” begins with a summary biography of Prince Saunders and an overview of the world of transatlantic slavery he was born into. Its major context is nineteenth century Anglo-European ideologies of freedom, equality, and citizenship. The dissertation also considers the origins of black revolutionary transnationalism by looking at its early pioneers and the revolutionary processes that widened the scope for the eventual success of antislavery to become an ideology rooted in human rights claims. Chapter 1 explores the late eighteenth century and the first decade of the nineteenth century as crucial periods in which free Blacks in the United States, slaves and freed people in Haiti, and British abolitionists embraced the morality that slavery and racism posed the greatest dangers to a world mired in revolutionary claims to natural rights. Part II, “Ideas and Ideologies,” considers how Saunders worked to frame the legacy of the Haitian Revolution as a democratic project that shaped the ideology of revolutionary transnationalism. In this view, citizenship was defined as unrestricted by national borders. By Saunders disseminating the idea of citizenship as transcending borders, the idea of Haiti became a radically subversive alternate to American citizenship. By propagating such views, Saunders transformed himself into a transcultural, bi-national hybrid American-Haitian, embodying the overall dynamism of black revolutionary transnationalism. Chapters 3 and 4 discuss the fusion of transatlantic abolitionism and Haitian revolutionary ideology into a full-fledged emigration idealism that showcases the operative capacity of Black citizenship. Part III, “The Era of Emigration and Colonization, 1816-1833, in Chapters 5 and 6 respectively grapples with the real consequences of African American emigration to Haiti and Prince Saunders’s legacy. The first wave of emigration from 1816–1826 was followed by a second wave from 1859-1865. In the interim, Blacks debated the relative merits of Haitian emigration versus colonization as a strategy for citizenship. The status of Haiti as a feasible home ebbed and flowed in the minds of Black emigrationists who increasingly viewed West Africa, as well as parts of Latin and South America or Canada, as options for escaping to citizenship. I conclude by exploring these debates for what they tell us about fragmentation and ruptures in the free Black community regarding the best strategies for reform and citizenship beyond the gaining or granting of freedom. It must be noted, however, that in the penultimate conclusion to Prince Saunders’s struggle, the coming of the Civil War and the Reconstruction period thereafter took African Americans away from the meaning and significance of Haiti. Finally, readers will note that each part and chapter of this volume is intended to synchronize with the whole but also stand as single-chapter essays.

This thesis addresses a creative writing approach to exploring reader empathy through the critical analysis of writing devices implemented by contemporary American short fiction writers and through creative experimentation through a written collection of short stories. It explores the ways in which writers can implement specific literary devices to potentially affect a reader's emotional reaction to a character or situation. The specified devices in this research have been utilised by contemporary American authors in their short fiction collections, namely Lydia Davis (The Collected Stories of Lydia Davis), George Saunders (Tenth of December), and David Foster Wallace (Brief Interviews with Hideous Men), who have influenced reader empathy in their short stories. Two categories of devices are in focus: narrative perspective and story format. These categories are signified due to contemporary American authors' experimentation with these devices and due to their inclusion in literary theory on reader empathy and fiction, namely Suzanne Keen's theory of narrative empathy. She focuses on the importance of reader empathy (namely, the effects that fiction can have on a reader in reality) and discusses devices that writers have used to possibly evoke these emotions. Keen explores the relationship between a reader and character identification, with a further emphasis on reader empathy and reader altruism in an inter-disciplinary setting, stating that reader empathy may lead to reader altruism; however, little to no research has been conducted on the creative implementation of writing techniques in regards to reader empathy from the perspective of a creative writer. Through creative application, this thesis aims to show the ways in which devices explored by narrative theorists can create the possibility for reader empathy. Therefore, the thesis takes into account first-, second-, and third-person narrative perspectives and question and answer (Q&A), short-short (a.k.a. flash fiction), and segmented formats through literary analysis of contemporary short fiction and through writing experimentation in the form of a short story collection. The thesis aims to explore the creative use of these devices and their linkage to reader reaction by the production of a short fiction collection entitled Fragmented Perceptions: A Collection of Characters. This creative work intends to implement the specified devices researched in order to experiment with perspective and format in relation to a possible empathetic connection of the reader to a character. Finally, by analysing possible effects on reader empathy through devices employed in the creative work, the thesis explores ways in which authors can use narrative perspective and format to discover various ways in which a writer can implement devices to affect reader empathy through short fiction.

Tais inferências podem ser feitas através da função de verossimilhança perfilada. Contudo, alguns problemas podem surgir quando tratamos a função de verossimilhança perfilada como uma verossimilhança genuína. Com o objetivo de solucionar estes problemas, vários pesquisadores, dentre eles Barndorff-Nielsen (1983, 1994) e Cox & Reid (1987, 1992), propuseram modificações à função de verossimilhança perfilada. O principal objetivo deste trabalho é utilizar a verossimilhança perfilada e seus ajustes propostos por Barndorff-Nielsen (1983,1994) e Cox & Reid (1987,1992) no aperfeiçoamento de inferências para a distribuição Birnbaum-Saunders generalizada com núcleos normal e t de Student, na presença, ou não, de censura tipo II. Mais precisamente obtemos os estimadores de máxima verossimilhança relacionados às funções de verossimilhança perfilada e perfiladas ajustadas; calculamos os intervalos de confiança do tipo assintótico, bootstrap percentil, bootstrap BCa e bootstrap-t e também apresentamos os testes da razão de verossimilhanças ajustados, o teste bootstrap paramétrico e o teste gradiente. Através de simulações de Monte Carlo avaliamos os desempenhos dos testes e dos estimadores pontuais e intervalares propostos. Os resultados evidenciam que tanto os testes quanto os estimadores baseados nas versões modificadas da verossimilhança perfilada possuem desempenho superior em pequenas amostras quando comparados com suas contrapartidas não modificadas. Adicionalmente, apresentamos alguns exemplos práticos para ilustrar tudo o que foi desenvolvido.

Since the end of World War II, the possibility of fascism and totalitarianism as a global threat continues to proliferate in American art and literature to the point that many individuals paradoxically desire the very things that seek to control them. Postmodern literature often portrays fascism and totalitarianism as it exists under contemporary capitalist systems as a multiplicity of discreet machines operating within objects of desire. These objects are complicated by the 24-hour news cycle and the popularity of solitary, on-demand entertainment that in turn mediates the desires and fears of a population through strict control of information. This thesis examines works by George Saunders, Don DeLillo, and David Foster Wallace through a post-structural lens and seeks to explore the moments in these novels where desire and fascism intersect to create an endless, self-replicating form of control that is often too discreet to notice.
