Suicide-authors : a deconstructive study

Loman, Lilia January 2005 (has links)
The purpose of this thesis is to problematize the relationship between suicide and the author. On the basis of a deconstructive approach, it will study the effect of the self-inflicted death of the writer, namely the emergence of a dual figure, the "suicide-author". To deconstruct the suicide-author, this thesis will combine theoretical issues with examples taken from authors who killed themselves, including texts written by the suicides and by their survivors. Such texts will be referred to as "memorial texts" and will constitute a key element in the deconstruction of the figure of the author, namely his/her "posthumous persona". The thesis is divided into two parts. Part I, comprising the first three chapters, will propose an anti-teleological theorizing of suicide, followed by a study of the role of memorial texts in the deconstruction of the figure of the suicide author and a problematizing of Roland Barthes's concept of the "death of the author" in the context of the multiplicity of deaths of the suicide-author. In Chapter Two, the study of memorial texts will be developed in conjunction with analysis of selected examples, such as Yukio Mishima, Mario de Sa-Carneiro, Vladimir Mayakovsky, Sergei Esenin, Raymond Roussel, Walter Benjamin, Anne Sexton, and Virginia Woolf. Also divided into three chapters, Part II is dedicated to an extended analysis of the thesis' case study, namely Sylvia Plath. Rather than focusing on Plath's suicide as an individual unique case, the second part aims at extending and complementing the discussion of the issues previously proposed. Of particular interest is the magnifying of such issues offered by the mythical aura of the Plath case. Chapter Four deals with the "voice of the other", the deconstruction of Plath's image by the living, including both those who had known her in person and the so called "anonymous witnesses" to her suicide, namely critics, journalists, et al. Chapter Five focuses on the "voice of the deceased", as emanating from Plath's writings. Finally, Chapter Six analyses the Plath-Hughes dialogue, with attention to Hughes's particular role in the deconstruction of her posthumous persona.

A Avaliação do Ciclo de Vida (ACV) de um produto abrange aspectos e impactos ambientais desde a aquisição da matéria-prima até a disposição final. A Avaliação do Ciclo de Vida Energético (ACVE), por sua vez, baseia-se na ACV com foco no consumo energético. Este estudo comparou o consumo energético da telha termoacústica com núcleo de EPS e a telha cerâmica tipo Plan, visando ultrapassar o senso comum sobre a eficiência da telha cerâmica. Foi calculada a Energia Incorporada total (EIT), considerando fases de Pré-Uso, Uso e Manutenção de quatro sistemas de vedação horizontal: telha termoacústica de Poliestireno Expandido com e sem laje de concreto; e telha cerâmica Plan com e sem laje de concreto. Todas essas situações foram analisadas para uma edificação habitacional unifamiliar, construída na região de São Sebastião/DF. O Desempenho Térmico também foi analisado e demonstrou que as telhas estudadas não atenderam todos os requisitos das normas brasileiras. Os resultados de energia demonstraram que o uso das telhas termoacústicas não representou economia energética em comparação à telha cerâmica, em todas as fases estudadas. Foi observado ainda que a laje de concreto aumentou significativamente o consumo de energia podendo acrescer em 10% o consumo energético ao final da vida útil. Verificou-se também que a tipologia da telha não foi um fator preponderante para a redução da energia ao longo da vida útil de uma edificação habitacional para o modelo estabelecido. ________________________________________________________________________________________________ ABSTRACT / The construction industry plays a significant role for sustainable development, because it is an important consumer of natural resources and a generator of environmental impacts. Life Cycle Assessment (LCA) of a product covers environmental aspects and impacts from procurement of raw materials to final disposal. Assessment of the Energy Life Cycle (LCA for Energy), in turn, is based on LCA, but the focus is on the energy consumption. This study compared the energy consumption of thermoacoustic tile with EPS core and ceramic tile type Plan, aiming to overcome common sense on the ceramic tile efficiency. Total Energy Incorporated was calculated (EIT) cradle-to-cradle of four horizontal sealing systems: thermoacoustic tile Expanded Polystyrene with and without concrete slab; Plan and ceramic tile with and without concrete slab. All these situations have been analyzed for a single-family residential building, built in the region of São Sebastião/DF. The Thermal Performance was also analyzed and showed that the tiles studied did not meet all the requirements of Brazilian standards. Energy results showed that the use of termoacústicas tiles did not represent energy savings compared to ceramic tile in all studied phases. It was also observed that the concrete slab significantly increased energy consumption (about 10%) until the end of life. It was also found that the type of tile was not a major factor in the reduction of energy over the lifetime of a residential building to the established model.

A exposição à radiação gama foi realizada com doses de até 200kGy utilizando uma fonte de cobalto-60. Foram feitas avaliações prévias sobre o efeito da radiação gama na estrutura do polímero por meio de ensaios de massa molar, espectroscopia no infravermelho e visível, e ensaios de absorção de líquido, em que foram comparados os resultados obtidos para os polímeros irradiados nas diferentes doses com os do não-irradiado. Os estudos de ESC consistiram em submeter os polímeros a ensaios de tração em diferentes taxas de deformação e relaxação de tensão sob líquido e sem líquido. Análises de microscopia ótica e eletrônica de varredura foram feitas na superfície de fratura após ensaios de ESC. A radiação gama promoveu intensas mudanças na massa molar do PMMA e PMMA-t e ocasionou apenas modificações moderadas no PS. As velocidades de absorção de etanol pelo PMMA e PMMA-t aumentaram com o aumento da dose. Para o PS a velocidade de absorção de querosene reduziu nas duas doses maiores (100 e 200kGy). O PMMA e o PMMA-t mostraram nítida dependência do efeito de ESC com a dose de radiação gama e com as condições de ensaio, evidenciada pela maior redução percentual da tensão de ruptura e deformação na ruptura verificada em ensaios realizados com líquidos em comparação aos sem líquido. O poliestireno mostrou a menor dependência do efeito de ESC com a dose de radiação gama

Nesse estudo foi utilizada a blenda de poli(cloreto de vinila)/poliestireno (PVC/PS), nas composições 95/05, 90/10, 70/30, 50/50 e 30/70. Com o objetivo de estudar a miscibilidade da blenda PVC/PS, empregando as técnicas de viscosimetria pelos modelos de Krigbaum-Wall, Garcia et al. e Pan et al. em solução; espectroscopia no infravermelho com transformada de Fourier (FT-IR), índice de refração e microscopia eletrônica de varredura (MEV), foram igualmente utilizadas. Embora a análise de miscibilidade por viscosimetria seja de fácil execução, os resultados da blenda PVC/PS mostraram-se diferentes, quando foram comparados os três modelos propostos. O modelo de Pan et al. foi o que mais se aproximou dos resultados obtidos, junto às técnicas de FT-IR e índice de refração, onde o resultado foi de imiscibilidade da blenda PVC/PS em toda a sua extensão. Por outro lado, quando as blendas foram irradiadas, o PS comportou-se como agente radioprotetor da matriz do PVC, devido a dissipação de boa parte de energia absorvida na ressonância existente no interior dos anéis aromáticos. O fator de proteção do PS foi calculado em 78 e 70% para as proporções de 95/05 e 90/10, respectivamente. A radiação gama, na dose de 50 kGy, também atuou no sistema como agente compatibilizante na blenda de composição 95/05. Mudanças nas propriedades mecânicas dos filmes de PVC, PS e nas blendas PVC/PS, na dose de esterilização (25 kGy) também foram observadas neste estudo

Dealing with the devil : a critical and creative look at the diabolical pact

Percak, Eric Charles January 2015 (has links)
This thesis is comprised of three parts: a critical dissertation, a creative work of fiction and a bridge piece that connects the two. The critical work is an examination of the Devil as a satirist in Faustian bargains. Through the usage of the Devil as a literary figure, his character has become a more secular being: a trickster rather than evil incarnate—a facilitator of sin rather than its originator. In the tragicomedy of pacts with the Devil, he acts as a mirror, reflecting mankind’s foibles and vanity, while elevating the reader in the process. The thesis considers the language, tone, purpose and conceits of several versions of the story. While the focus is primarily on American Literature, the influence of English, Scottish, French and German folklore and fiction are recognized as an essential component of the theme’s evolution. In the bridge piece, the pact with the Devil is literalized in a modern context; a corporate business of reaping souls is theorized in which techniques of persuasion are streamlined into an effective formula. Whether immersive or expository in approach, the portrayal of the supernatural depends on the literary principles of science fiction and fantasy in order to manipulate the reader and allow irrational concepts to obey rational laws. Such theories are cited to support how the Devil functions as a believable character. The novel, Could Be Much Worse, relates the story of an egocentric boss and his dependable employee, a scout who disguises himself as a taxi driver and seeks candidates who may succumb to temptation. Passengers’ monologues of desperation and pathos are interspersed throughout the protagonist’s day-to-day narrative. At times, the work is experimental, utilizing irregular storytelling techniques, alternative forms and conceits. Light-hearted, but nonetheless poignant, the story serves as a cautionary tale, illustrating the tedium of a bureaucratic job in a transmundane existence.

ESTETISK VÄGPLANERING : Prestanda hos A*PS och Theta* / AESTHETIC PATHFINDING : Performance of A*PS and Theta*

Wahlström, Jon January 2015 (has links)
Arbetet undersöker prestanda och estetik hos A*PS och Theta* inom olika miljötyper, där miljötyper är ett generaliserat begrepp för spelmiljöer och innefattar en struktur samt ett antal blockerande objekt. Båda teknikerna är varianter av A*-algoritmen och används för att åstadkomma estetisk vägplanering. Vägplanering innebär att finna en kortaste väg från en punkt A till en punkt B i en graf. En populär grafrepresentation i spel är rutnät med blockerande och icke-blockerande noder. Ett problem med rutnät är att algoritmerna tenderar att planera sina vägar längst med kanterna och därav resultera i sicksackformade vägar. A*PS och Theta* löser detta genom att utföra estetiska optimeringar som tillåter vägplaneringen att göras längst med grafens kanter, men samtidigt inte låta vägarna begränsas till att direkt följa dessa. Med experiment visar arbetet att Theta* i majoriteten av fallen hittar kortare och mer realistiska vägar. Vidare föreslås framtida arbeten inom området.

Alice Walker's womanist fiction : tensions and reconciliations

Hami, Iman January 2016 (has links)
A theory formulated by Alice Walker, womanism focuses on the unification of men and women with Nature and Earth. This thesis explores womanism with regards to its specific concerns with African American women’s rights, identities, and self-actualisation, and points towards its more overarching concerns with human relations and sexual freedom, as expressed in each of Walker’s seven novels. The seven novels discussed in the thesis are The Third Life of Grange Copeland (1970), Meridian (1976), The Color Purple (1982), The Temple of My Familiar (1989), Possessing the Secret of Joy (1992), By the Light of My Father’s Smile (1998), and Now Is the Time to Open Your Heart (2004). Although Walker introduces the term “womanism” in 1983, this thesis traces the development of the concept across her canon of fictional works. By analysing the novels written in the 1970s, I establish how the term came to be coined, and, by seeing through themes and issues addressed early on and how they can be mapped through analysis of her later works, I demonstrate how womanism went on to be further developed and complexly wrought. This thesis thus examines how Alice Walker’s own theory of womanism is reflected through the oeuvre of her fictional works, and considers where tensions arise in her application of what is intended to be a universalist, humanist, project. For, in many of her novels, it is women’s sexuality and sexual power that are the focus, often at the cost of developing the potential of male characters’ equivalent attributes. However, as will be argued, it is in Walker’s later, less appreciated, works that womanism is more fully developed in its universal claims. The integration of spiritual themes and concepts into her narratives reduce or remove the tensions that arise in the reconciliation between woman and man, as well as between humanity and nature.

Between times : 21st century American fiction and the long sixties

West, Mark Peter January 2014 (has links)
This thesis examines conceptions of time and history in five American novels published between 1995 and 2012 which take as their subject matter events associated with the counterculture and New Left of the 1960s and 1970s. The thesis is organized around close readings of five novels. The first chapter focuses on Jennifer Egan’s The Invisible Circus (1995) and argues that it incorporates a number of problematic temporal experiences which have the effect of establishing a key tension of all the novels considered here: the concern with contextualizing and historicizing particular events and cultural atmospheres while remaining faithful to utopian ideas of radical change. Chapter two argues that Dana Spiotta’s Eat the Document (2006) is oriented both structurally and thematically towards a future in which the relationship between the 1960s and 1990s will more clearly understandable. The third chapter examines the way Christopher Sorrentino’s Trance (2005) explores the multiplicitous nature of historical narratives, and how he distinguishes between those narratives and a conception of the bare events beneath them. The focus of chapter four is Lauren Groff’s Arcadia (2012) and examines how conceptions of the relationship between humans and nature influence theories of time, mythic histories and post-apocalyptic narratives. The final chapter on David Foster Wallace’s The Pale King (2011) argues that the tension between continuation and change found in the conversion narrative is partly reconciled by a conception of time that allows the moment of radical utopian change (the moment of conversion) to be one of re-entrance into history. At stake throughout is the way these novels’ interpretation of particular events and larger cultural tendencies reveals and makes manifest various processes of historicization. I maintain a dual focus on the way these novels present historicization as something undertaken by individuals and societies and the ways in which these novels themselves not only engage in historicizations of the period but are in various ways self-conscious about doing so. If contemporary scholarship on the emergence of what has been called post-postmodern literature (Stephen J. Burn, Andrew Hoberek, Adam Kelly, Caren Irr) identifies a return to temporal concerns in recent fiction, the readings that comprise my thesis also make use of conceptions of time and history by Mark Currie, Jacques Derrida, Reinhold Niebuhr, Norman Mailer, Christopher Lasch, and Robert N. Bellah (among others) in order to ask: what are the particular material contours of the experiences of time and history manifested in these recent examples of the ‘sixties novel’?

Sjuksköterskors upplevelser av samarbete och samverkan i prehospital sjukvårdsledning : En intervjustudie / Nurses’ Experiences of Cooperation and Collaboration in Prehospital Management Leadership

Näsström, Tomas, Ryberg, Gustav January 2016 (has links)
Bakgrund: För ett fungerande skadeplatsarbete krävs det att sjuksköterskor i ledningsfunktion har ett fungerande samarbete internt inom ambulansverksamheten samt i samverkan med övriga räddningsinstanser. Den enskilde sjuksköterskan hamnar sällan i uppdrag där behov finns av ledningsfunktion. För att vara trygg i, samt effektivt kunna utföra, arbetet i ledningsfunktion har forskning visat att utbildning och erfarenhet krävs. Vid bristande ledning har kommunikationsbortfall blivit en konsekvens som lett till att personal inte tilldelats relevanta uppgifter, vilket i förlängningen har äventyrat patientsäkerheten. Syfte: Att beskriva sjuksköterskors upplevelser av samarbete och samverkan i prehospital sjukvårdsledning. Metod: Studien utfördes som en kvalitativ intervjustudie med deskriptiv design. Åtta sjuksköterskor deltog. De var utbildade i, och hade erfarenhet av, prehospital sjukvårdslednings-konceptet (PS-konceptet) och intervjuades genom semistrukturerade intervjuer. Datamaterialet analyserades med kvalitativ innehållsanalys. Resultat: I resultatet framkom fem kategorier; Att följa rutiner och riktlinjer underlättar/främjar skadeplatsarbetet; Att kommunikation är avgörande för ett effektivt skadeplatsarbete; Att personkännedom underlättar skadeplatsarbete; Att brist på tydlighet och känslor av osäkerhet hämmar samarbete och samverkan; Att önskan finns om mer övningar. Genom dessa kategorier formulerades temat; Optimalt omhändertagande kräver samövad personal i ledningsfunktion. Konklusion: Sjuksköterskor är i behov av kontinuerlig praktisk och teoretisk övning inom den egna verksamheten, samt med personal från samverkande verksamheter. Detta för att sjuksköterskor i ledningsfunktion ska kunna leda och organisera arbetet på skadeplats och därmed säkerställa ett optimalt omhändertagande av patienten som är patientsäkert och av hög kvalitet.

Výroba těstovin z netradičních surovin

Tesař, Miroslav January 2018 (has links)
The aim of the thesis was to produce pasta using unusual raw materials, especially colored varieties of wheat. The literary research describes input raw materials for pasta production with a deeper focus on both standard and nontraditional varieties of wheat with different color of wheat. Here are examples of color variations of wheat, colorants responsible for colouration of wheat and use of these varieties in technology of pasta. An important part is the principle of pasta production. The practical part of this work includes the evaluation of nine proposed pasta recipes, which were made in the university laboratory. The recipe for pasta samples is made of semolina and whole wheat flour of two colored wheat varieties: Skorpion variety with blue aleuron and PS Karkulka variety with purple pericarp. The assessment of the quality of the produced pasta samples includes cooking, texture and sensory evaluation.
