"How to make a mountain out of a molehill": a corpus-based pragmatic and conversational analysis study of hyperbole in interation.

Cano Mora, Laura 30 January 2006 (has links)
Since antiquity figures have been widely studied within the framework of rhetoric, although contemporary rhetoric has tended to disregard their importance and relegate their study to the domain of literary criticism. However, since the 1980s, there has been a renewed interest in figurative language not only in literary studies, but also in other fields of research. Indeed, research on figuration has emerged as a new and distinct discipline, namely figurative language studies. However, within this framework, metaphor and irony have received the greatest attention, while other non-literal forms have been largely ignored. This is certainly the case of hyperbole, a long neglected trope despite its ubiquity in discourse. The present study aims to make a contribution to the literature on exaggeration and so by extension to figurative language theories in general.Not all aspects of figuration have attracted equal interest among researchers. With a few exceptions, most attention has been directed at explaining how figures are comprehended, given their non-literal nature. In contrast to understanding, the question of production has been largely ignored. Similarly, although the reception process, in terms of understanding, has been widely studied, almost no attention has been devoted to listeners' responses to figures and their collaboration in a joint construction of non-literal frames.Rather than addressing comprehension, this study concentrates on the production process and usage of exaggeration, since these fields of research have been largely ignored in the literature on the subject. It aims to provide a general framework for the description and understanding of hyperbole in interaction, mainly from a production viewpoint but without totally disregarding the reception process, since special attention is devoted to the interactive dimension of exaggeration. This aim is formulated in terms of the following objectives:Objective 1: to provide an adequate definition of the notion of hyperbole; to list the criteria for identifying the trope so that non-exaggerated uses of expressions can be excluded.Objective 2: to set up a classification of overstated items according to semantic field, grammatical category, auxesis or meiosis, and interactivity with other figures.Objective 3: to explore the long neglected production process of hyperbole, both in terms of usage and functions.Objective 4: to examine the interactive nature of the trope, as an activity collaboratively constructed between speaker and hearer, by studying listeners' reactions and their own further contributions to overstatement.As for the theoretical framework, this study combines pragmatic and conversational-analytical methods with a corpus-based approach to the study of hyperbole. Exaggeration is a purely pragmatic phenomenon since it is entirely dependent on context. On the other hand, since overstatements are not one-off but complex lexico-grammatical items, they need to be examined within the constraints of placement, sequencing and turn-taking of conversational analysis. Finally, a major benefit of corpus-based research, only recently applied to the study of figures, is that it grounds its theorising on empirical observation rather than linguistic intuition. Besides, the use of corpora grants certain benefits, such as the use of naturalistic data, automatic access to context, evidence of interactivity and hyperbolic cues, wide coverage of genres, etc.The data examined consists of naturalistic spoken texts, totalling 52,000 words, extracted from the British National Corpus. The focus is on oral discourse, since not a great amount of research exists into everyday spoken hyperbole. The bulk of research has been conducted in written language or relies on artificial and elicited data. The aim was to demonstrate that although traditionally relegated to the literary text, hyperboles are rather ubiquitous strategies in everyday language. This idea adheres to a prevailing view among figurative language researchers, namely that cognition is partly figurative. / El lenguaje figurado ha sido, desde antiguo, ampliamente estudiado en el marco de la retórica. Más recientemente, las figuras retóricas parecen haber despertado un nuevo interés en otras disciplinas. De hecho, dichos estudios están empezando ya a ser considerados como una disciplina en sí: las teorías del lenguaje figurado. Dentro de este marco, metáfora e ironía han sido ampliamente estudiadas y como consecuencia de su estudio intensivo, otras figuras han sido marginadas. Éste es el caso de la hipérbole, figura retórica largo tiempo olvidada a pesar de su ubicuidad y tradicionalmente relegada al dominio de la crítica literaria.El presente estudio, en lugar de examinar el proceso de comprensión, se centra en la producción y uso de la exageración, temas escasamente tratados en la literatura existente. Intenta proporcionar un marco general para la descripción y comprensión de la hipérbole en la interacción, principalmente desde el punto de vista de la producción, pero sin descartar del todo el proceso de recepción, dado que su dimensión interactiva como figura creada conjuntamente entre hablante y oyente cobra especial relevancia. Dicho propósito se materializa en los siguientes objetivos:Objetivo 1: proporcionar una definición adecuada de la noción de exageración que nos permita diferenciarla de figuras afines y excluir los usos no exagerados de las expresiones.Objetivo 2: clasificar los elementos hiperbólicos de acuerdo con los siguientes parámetros: campo semántico, categoría gramatical, auxesis o meiosis, e interacción con otras figuras.Objetivo 3: explorar el descuidado proceso de producción de la figura en términos de uso y función.Objetivo 4: examinar la naturaleza interactiva del tropo, como actividad conjunta entre hablante y oyente, mediante el estudio de las respuestas y demás contribuciones del receptor al acto hiperbólico del hablante.Este estudio fusiona tres tipos de enfoque: pragmática, análisis conversacional y lingüística de corpus, a la hora de estudiar la exageración en el discurso oral, dado que son escasos los estudios de esta figura en el habla cotidiana. El corpus examinado abarca unas 52.000 palabras y es una selección de textos orales extraídos del British National Corpus.

Then, we made an approach to concepts of linear algebra, vector spaces, linear transformations, eigenvalues and eigenvectors in order to build matrices of linear transformations able to rotate, translate or even make these conical shear. Constructed matrices, GeoGebra software for constructing graphs obtained by transformation matrices were used. Besides this geometric part, we discuss the quadratic forms in order to identify a conic analyzing only the coe cients of its quadratic form and the eigenvalues. The end result was an excellent visual material built from software GeoGebra applying the concepts of Linear Algebra. We can not fail to mention that the construction of the taper in GeoGebra techniques that replace the ruler, compass and the string used by the ancient Greeks were implemented. / Na primeira parte desse trabalho, apresentamos todas as cônicas com suas respectivas equações cartesianas e seus respectivos grá cos. Em seguida, zemos uma abordagem de conceitos de Álgebra Linear, espaços vetoriais, transformações lineares, autovalores e autovetores a m de, construir as matrizes de transformações lineares capazes de rotacionar, transladar ou até fazer o cisalhamento destas cônicas. Construídas as matrizes, foi utilizado o software GeoGebra para a construção dos grá cos obtidos pelas matrizes de transformação. Além dessa parte geométrica, abordamos as formas quadráticas no intuito de identi car uma cônica analisando apenas os coe cientes da sua forma quadrática e os autovalores associados. O resultado nal foi um excelente material visual construído a partir do software GeoGebra aplicando os conceitos de Álgebra Linear. Não podemos deixar de citar que foram implementadas técnicas de construção das cônicas no GeoGebra que substituem a régua, o compasso e o barbante utilizados pelos gregos antigos.

A geometria de algumas famílias tridimensionais de sistemas diferenciais quadráticos no plano / The geometry of some tridimensional families of planar quadratic differential systems

Rezende, Alex Carlucci 22 September 2014 (has links)
Sistemas diferenciais quadráticos planares estão presentes em muitas áreas da matemática aplicada. Embora mais de mil artigos tenham sido publicados sobre os sistemas quadráticos ainda resta muito a se conhecer sobre esses sistemas. Problemas clássicos, e em particular o XVI problema de Hilbert, estão ainda em aberto para essa família. Um dos objetivos dos pesquisadores contemporâneos é obter a classificação topológica completa dos sistemas quadráticos. Devido ao grande número de parâmetros (essa família possui doze parâmetros e, aplicando transformações afins e reescala do tempo, reduzimos esse número a cinco, sendo ainda um número grande para se trabalhar) usualmente subclasses são consideradas nas investigações realizadas. Quando características específicas são levadas em consideração, o número de parâmetros é reduzido e o estudo se torna possível. Nesta tese estudamos principalmente duas subfamílias de sistemas quadráticos: a primeira possuindo um nó triplo semielemental e a segunda possuindo uma selanó semi elemental finita e uma selanó semielemental infinita formada pela colisão de uma sela infinita com um nó infinito. Os diagramas de bifurcação para ambas as famílias são tridimensionais. A família tendo um nó triplo gera 28 retratos de fase topologicamente distintos, enquanto o fecho da família tendo as selasnós dentro do espaço de bifurcação de sua forma normal gera 417. Polinômios invariantes são usados para construir os conjuntos de bifurcação e os retratos de fase topologicamente distintos são representados no disco de Poincaré. Os conjuntos de bifurcação são a união de superfícies algébricas e superfícies cuja presença foi detectada numericamente. Ainda nesta tese, apresentamos todos os retratos de fase de um sistema diferencial conhecido como modelo do tipo SIS (sistema suscetívelinfectadosuscetível, muito comum na matemática aplicada) e a classificação dos sistemas quadráticos possuindo hipérboles invariantes. Ambos sistemas foram investigados usando de polinômios invariantes afins. / Planar quadratic differential systems occur in many areas of applied mathematics. Although more than one thousand papers have been written on these systems, a complete understanding of this family is still missing. Classical problems, and in particular Hilberts 16th problem, are still open for this family. One of the goals of recent researchers is the topological classification of quadratic systems. As this attempt is not possible in the whole class due to the large number of parameters (twelve, but, after affine transformations and time rescaling, we arrive at families with five parameters, which is still a large number), many subclasses are considered and studied. Specific characteristics are taken into account and this implies a decrease in the number of parameters, which makes possible the study. In this thesis we mainly study two subfamilies of quadratic systems: the first one possessing a finite semielemental triple node and the second one possessing a finite semielemental saddlenode and an infinite semielemental saddlenode formed by the collision of an infinite saddle with an infinite node. The bifurcation diagram for both families are tridimensional. The family having the triple node yields 28 topologically distinct phase portraits, whereas the closure of the family having the saddlenodes within the bifurcation space of its normal form yields 417. Invariant polynomials are used to construct the bifurcation sets and the phase portraits are represented on the Poincaré disk. The bifurcation sets are the union of algebraic surfaces and surfaces whose presence was detected numerically. Moreover, we also present the analysis of a differential system known as SIS model (this kind of systems are easily found in applied mathematics) and the complete classification of quadratic systems possessing invariant hyperbolas.
