"I' ll tell you a story that will make you believe" in narratives: the role of metafiction in the novel and in the film Life of Pi
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Inglês: Estudos Linguísticos e Literários, Florianópolis, 2015.Recentes estudos propõem que adaptações cinematográficas sejam entendidas como fonte de criação, os quais refletem contextos e interpretações diferentes do texto em que são baseadas. Nessa dissertação, propõe-se uma análise comparativa do romance Life of Pi (2001), de Yann Martel e do filme homônimo dirigido por Ang Lee (2012). A análise tem como objetivo identificar a presença e o modo em que a metaficção é construída no romance e no filme, e quais são alguns significados produzidos por ela em ambos os textos, tanto o literário quanto o fílmico. A concepção de metafição se baseia nas definições de Linda Hutcheon e Patricia Waugh. Por metaficção, entende-se a ficção consciente de si, que expõe o processo de escrita ao leitor e o convida a ter um papel ativo na construção do significado. Após uma análise comparativa dos dois textos, conclui-se que a metaficção está presente em ambos, tanto tematicamente como estruturalmente. As reflexões sobre narrativas apresentadas pelos personagens, o uso de vários níveis narrativos e de intertextualidade revelam diferentes usos da metafição em ambos. A diferença mais importante entre o romance e o filme Life of Pi está no uso dos níveis narrativos. Enquanto o romance possui um ?autor? sem nome que apresenta a história aos leitores, o filme possui um diretor implícito que deixa pistas de qual versão da história de Pi é ?real? no contexto da narrativa. Essa diferença dá ao romance um final aberto, em que o leitor deve escolher qual versão da história ele acredita, enquanto o filme possui uma resolução para essa questão. O filme, então, pode ser entendido como um testemunho, uma narrativa de trauma de um sobrevivente de um naufrágio e da experiência de migração, enquanto o livro não apresenta uma decisão em relação às versões da história, deixando o leitor aberto a qualquer possibilidade.Abstract : Recent studies propose that Film Adaptations should be understood as sources of creation, which also reflect a different context and interpretation from the text upon which they were based. In this thesis, I propose a comparative analysis of the novel Life of Pi (2001), by Yann Martel, and the homonymous film directed by Ang Lee (2012). The analysis has the objective of identifying the presence and the way in which metafiction is constructed in the novel and in the film, and what are some of the meanings produced by it in both texts, the filmic and the literary. The concept of metafiction was based on the definitions by Linda Hutcheon and Patricia Waugh. It is understood as the self-conscious fictional text, which exposes the writing process to the readers and invites them to have an active role in the construction of meaning. In the comparative analyses of the two texts, I have proved that metafiction is present in the two texts, both thematically and structurally. The reflections of the characters on narrative itself as well as the use of different narrative levels and intertextual references reveal different uses of metanarrative in both film and novel. The most important difference between the novel and the film Life of Pi is in their uses of different narrative levels. While the novel has an unnamed =author? who presents the story to the readers, the film has an implicit director who leaves =clues? of which version of Pi?s story is ?real? in the context of the narrative. This difference gives to the novel an open end, facein which the readers must choose which version of the story they believe in, while the film presents a resolution to this question. The film, thus, can be understood as a testimony narrative, a narrative of the trauma of a survivor from a shipwreck and from the experience of migration, while the novel does not decide for one of the versions of the story, enabling a more inconclusive reading

Conservación vial de Heredia y Alajuela LPCO 14-01
No full textLa Auditoría detecta, con base en la documentación solicitada y a las entrevistas realizadas al personal asignado al proyecto detectó deficiencias en cuanto al control de calidad de los trabajos realizados por el contratista, al no exigir oportunamente la construcción de franjas de control o paños de prueba de compactación conforme lo establece el cartel de licitación. Este problema de control de calidad también se refleja en el proceso de extracción de núcleos que se hace de forma extemporánea, en incumplimiento claro con los plazo establecidos en el cartel de licitación.
La mezcla asfáltica producida para el proyecto de Conservación Vial de Heredia y Alajuela (LPCO-14-01) presenta en el periodo evaluado por el Lanamme incumplimiento en cuanto a los vacíos. Este es un parámetro de evaluación de la mezcla asfáltica muy importante que determina en gran medida la durabilidad de los trabajos realizados (bacheos o sobrecapas). La presencia de vacíos muy bajos (menores a 3.5%) es una condición característica de mezclas propensas a deformarse prematuramente, a presentar problemas de exudación y a manifestarse en capas de rodamiento con excesiva lisura.
La planta no cuenta con planes definidos en cuanto evaluación, verificación o mantenimiento de cada uno de sus componentes electro mecánicosThe Audit detects, based on the requested documentation and the interviews carried out with the personnel assigned to the project, that it detected deficiencies in the quality control of the work carried out by the contractor, by not requiring the construction of control strips or test strips in a timely manner. compaction as established by the bidding poster. This problem of quality control is also reflected in the process of core extraction that is done extemporaneously, in clear breach with the term established in the bidding poster.
The asphalt mixture produced for the Road Conservation project of Heredia and Alajuela (LPCO-14-01) presents, in the period evaluated by the Lanamme, a breach of the gaps. This is a parameter of evaluation of the very important asphalt mixture that determines to a great extent the durability of the work carried out (patching or overlapping). The presence of very low voids (less than 3.5%) is a characteristic condition of mixtures prone to deform prematurely, to present problems of exudation and to manifest in layers of rolling with excessive smoothness.
The plant does not have defined plans regarding evaluation, verification or maintenance of each of its electro-mechanical components.UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ingeniería::LanammeUC
Tangle-bearing neurons survive despite disruption of membrane integrity in a mouse model of tauopathy
No full textNeurofibrillary tangles (NFTs) are associated with neuronal loss and correlate with cognitive impairment in Alzheimer disease, but how NFTs relate to neuronal death is not clear. We studied cell death in Tg4510 mice that reversibly express P301L mutant human tau and accumulate NFTs using in vivo multiphoton imaging of neurofibrillary pathology, propidium iodide (PI) incorporation into cells, caspase activation, and DNA labeling. We first observed that in live mice, a minority of neurons were labeled with the caspase probe or with PI fluorescence. These markers of cell stress were localized in the same cells and appeared specifically within NFT-bearing neurons. Contrary to expectations, the PI-stained neurons did not die during a day of observation; the presence of Hoechst-positive nuclei in them on the subsequent day indicated that the NFT-associated membrane disruption, as suggested by PI staining, and caspase activation do not lead to immediate death of neurons in this tauopathy model. This unique combination of in vivo multiphoton imaging with markers of cell death and pathological alteration is a powerful tool for investigating neuronal damage associated with neurofibrillary pathology
Amplitude analysis of D-0 -> K- pi(+) pi(+) pi(-)
No full textKolcu, Onur Buğra (Arel Author)Kolcu, Onur Buğra (Arel Author)We present an amplitude analysis of the decay D-0 -> K- pi(+)pi(+)pi(-) based on a data sample of 2.93 fb(-1) acquired by the BESIII detector at the psi(3770) resonance. With a nearly background free sample of about 16000 events, we investigate the substructure of the decay and determine the relative fractions and the phases among the different intermediate processes. Our amplitude model includes the two-body decays D-0 -> (K) over bar*(0)rho(0), D-0 -> K- a(1)(+) (1260) and D-0 -> K-1(-)(1270)pi(+), the three-body decays D-0 -> K-1(-)*(0)pi(+)pi(-) and D-0 -> K- pi(+)rho(0), as well as the four-body nonresonant decay D-0 -> K- pi(+)pi(+)pi(-). The dominant intermediate process is D-0 -> K(-)a(1)(+)(1260)accounting for a fit fraction of 54.6%.We present an amplitude analysis of the decay D-0 -> K- pi(+)pi(+)pi(-) based on a data sample of 2.93 fb(-1) acquired by the BESIII detector at the psi(3770) resonance.
