Defesa: Curitiba, 26/06/2013Bibliografia: fls. 158-161Área de concentração: Estudos LiteráriosResumo: O propósito deste trabalho é refletir sobre a construção do foco narrativo em Author, Author (2004), de David Lodge, romance biográfico sobre o escritor Henry James (1843-1916). O narrador não se limita a situar o leitor na narrativa: o seu posicionamento em relação aos aspectos factuais da vida e do percurso literário do romancista norte-americano desempenha papel fundamental na discussão das estratégias narrativas da prosa de ficção de James. Na construção ficcional do malogro na noite de estreia de Guy Domville, em Londres, em 1895, por exemplo, é possível perceber a bipartição desse narrador, capaz de contar e mostrar dois episódios que se passam em dois lugares diferentes, simultaneamente. Em outros momentos do romance, a voz autoral embaralha-se com a voz do sujeito da enunciação a tal ponto, que o leitor menos atento encontra certa dificuldade para colocar ordem nos discursos. O abandono gradual da prosa de ficção em busca de uma identidade como dramaturgo, a falta de êxito na dramaturgia, a lenta recuperação psicológica, a retomada da prosa de ficção e o resultado insatisfatório da revisão e escrita de prefácios para as suas obras, para compor The novels and tales of Henry James:The New York Edition (1905), são alguns dos desdobramentos da trajetória de James, discutidos em Author, Author.Abstract: The purpose of this dissertation is to think over the construction process of narrative focus in Author, Author (2004), by David Lodge, a biographical novel about the writer Henry James (1843-1916). The narrator does not limit himself to guiding the reader through the narrative; rather, his attitude towards factual aspects of the life and literary course of the North-American novelist seems to play a fundamental role in the novel. In the fictional construction of the débâcle of "Guy Domville", in London, 1895 for instance it is possible to distinguish the narrator's bipartition, in order to tell and show two different episodes which happen in two different places, simultaneously. In other moments, the authorial voice blends with that of the subject of the enunciation to such a degree that the less attentive reader may not be capable of organizing the discourse, in a first moment. James' gradual movement away from prose fiction so as to find his playwright identity; the lack of success as a playwright; his subsequent slow psychological recovery; the return to prose fiction; and, finally, the weak result of writing and revising prefaces to his literary works in order to put together The Novels and Tales of Henry James: The New York Edition (1905), are some of the most conspicuous events in James' trajectory discussed in Author, Author
Improved Multichannel Electromyograph Using Off-the-Shelf Components for Education and Research
No full textMost students and researchers with limited funding are often looking for simple and low-cost devices for the acquisition of the electromyogram signal (EMG) in an educational or research setting. Thus, off-the-shelf devices are used and they have already been described in the literature, but they are used without considering their real performances, which are, in general, quite poor from the electronic and signal processing points of view. It is the purpose of this communication to present the evidence of these issues, and to describe an improved version of the “classical” duo, composed of the common ECG/EMG Olimex board and the Arduino microprocessor board. In this case, the Arduino-DUE is used. Three main points are highlighted in this paper: (a) the bandpass characteristics of the ECG/EMG Olimex board and how they can be improved to cope with EMG bandwidth requirements; (b) the increase in sampling frequency of the signal; and, finally, (c) the possibility of automatic detection of more ECG/EMG Olimex boards installed at the same time as the shields on the Arduino-DUE board. Very simple and low-cost modifications on the ECG/EMG Olimex board could deliver a much better performing multichannel EMG acquisition system, suitable for educational classroom experiments and early proof-of-concept research
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
The reability of the bilateral trigeminal roots-motor evoked potentials as an organic normalization factor: symmetry or not symmetry?
No full textImplant primary stability and occlusion
No full textIn this chapter, we have focused on the primary implant stability not only from a biomechanical bone-implant perspective but also taking into account the neuromotor functions that could generate occlusal dynamic, asymmetric, and extra-axial loads.From the biomechanical bone-implant perspective, a microcomputed tomography image-based approach combined with the finite element method has been used to investigate the effect of the drill size on the biomechanics stability of the dental implant technique.In the case of neuromotor functions, to achieve a complete clinical evaluation of mastication, an in-depth neurophysiopathological assessment of masticatory muscle control has been described through the trigeminal electrophysiological approach.In conclusion, the implant-prosthetic primary stability is a biomechanical result in a "complex system" in which the direct components can coexist, such as the bone-implant relationship (press-fit phenomenon), and indirect components such as the occlusal loads are determined by the neuromuscular forces where the symmetry and synchronicity of the occlusal contacts are determined
Método e teoria em Ludwig Von Mises
No full textOrientador: José Guilherme Silva VieiraMonografia(Graduação) - Universidade Federal do Paraná,Setor de Ciências Sociais Aplicadas, Curso de Ciências EconômicasResumo: Analisam-se os escritos metodológicos e econômicos de Ludwig von Mises, autor por quem tem crescido o interesse no Brasil. Boa parte da obra do economista austríaco é dedicada a justificar o método, fundado em sua teoria da ação humana, a Praxeologia. No presente trabalho, procura-se saber se o autor efetivamente fez uso de tal método. Para entender o que a Praxeologia representava para Mises, faz-se uma pequena revisão histórica das discussões metodológicas em voga no tempo de Mises, além de uma comparação entre o Historicismo, o Positivismo e a Praxeologia. A análise segue com o levantamento de algumas das críticas sofridas pela Praxeologia e das defesas apresentadas por Mises. É argumentado que alguns dos seguidores, na tentativa de validar o método praxeológico, perverteram a intenção original que Mises tinha ao criar um método apriorístico. Alguns dos limites desse método se refletem na teoria monetária e por isso são estudados mais a fundoAbstract: Ludwig von Mises’, an author for whom the interest has rised in Brazil, methodological and economic works are analysed. A great share of the Austrian economist’s work was dedicated to justify his method, based on his theory of human action, Praxeology. The present work investigates if the author actually used his that method. A small historical review of the methodological debate in Mises’s time and a comparison between Historicism, Positivism and Praxeology are made in order to properly understand what Praxeology meant for Mises. The analysis follows with some of the critiques made against Praxeology and the answers Mises had for them. It’s shown that some of the attempts of Mises’ heirs to defend Praxeology perverted his original intention with the a priori method. Some of the limits of this method are analysed more carefully for they have implications on monetary theor
A New Algorithm for Estimating a Noiseless, Evenly Sampled, Heart Rate Modulating Signal
No full textHeart rate variability (HRV) is commonly intended as the variation in the heart rate (HR), and it is evaluated in the time and frequency domains with various well-known methods. In the present paper, the heart rate is considered as a time domain signal, at first as an abstract model in which the HR is the instantaneous frequency of an otherwise periodic signal, such as with an electrocardiogram (ECG). In this model, the ECG is assumed to be a frequency modulated signal, or carrier signal, where HRV or HRV(t) is the time-domain signal which is frequency modulating the carrier ECG signal around its average frequency. Hence, an algorithm able to frequency demodulate the ECG signal to extract the signal HRV(t) is described, with possibly enough time resolution to analyse fast time-domain variations in the instantaneous HR. After exhaustive testing of the method on simulated frequency modulated sinusoidal signals, the new procedure is eventually applied on actual ECG tracings for preliminary nonclinical testing. The purpose of the work is to use this algorithm as a tool and a more reliable method for the assessment of heart rate before any further clinical or physiological analysis
