The Psychology of Theatre and Film: In Theory and Practice

Watson, Ian T 01 January 2016 (has links)
This thesis utilizes theories and ideas from the field of psychology to inform intertextual and interdisciplinary readings that compare and contrast theatre and film texts. In Chapter One, I compare Carlos Fuentes' drama Orchids in the Moonlight to Nicolas Winding Refn's film Bronson in order to investigate the extent each oscillates between Carl Jung's notion of the collective unconscious and Gilles Deleuze and Félix Guattari's schizoanalytic paradigm. I found that while these vacillating aspects helped illuminate different perspectives of each text, Orchids in the Moonlight more closely represents the collective unconscious, while Bronson more robustly embodies schizoanalysis. In Chapter Two, I examine the magnitude to which the play and film version of Jean Cocteau's Orpheus illuminate his self-portrait. By analyzing the similarity and differences between how Cocteau depicts mirrors and the female personification of Death, I discovered the film version to more profoundly evoke and depict Cocteau's self-portrait. Finally, in Chapter Three, I discuss my process of writing a new play with film elements called Flooded—before providing a sample of the text, and later analyzing the advantages and disadvantages of the film contents in the play.

Développement d'une méthode de comparaison de données asynchrones en vue de la formalisation d'un raisonnement par analogies : application à l'aide à la décision en viticulture / Development of a method to compare asynchronous data to a future analogy-based reasoning : application to decision support in viticulture.

Dupin, Séverine 03 July 2012 (has links)
L'objectif initial de ce travail de thèse est de valoriser les informations relatives au suivi temporel de la vigne, du raisin et de l'environnement de la plante et enregistrées dans des bases de données (BD) de traçabilité pour permettre la comparaison entre parcelles et millésimes, en vue de décisions par analogies.Les travaux réalisés durant cette thèse ont permis de proposer une méthode de transformation qui permet de représenter des ensembles de données asynchrones dans un espace commun afin de les comparer. Cette méthode s'appuie sur l'expertise du système de production. Dans ce travail de thèse, cette méthode a été appliquée à la comparaison de couples parcelle×millésime.L'expertise du système de production viticole permet, dans une première phase, de définir (i) la forme générale de la cinétique d'évolution de grandeurs de mesures évaluées sur la vigne, le raisin ou l'environnement de la plante et (ii) l'effet du climat sur la plante. Cette expertise est utilisée, dans une seconde phase, pour proposer des modèles paramétriques de l'évolution de chaque grandeur. Les données de suivi de chaque couple parcelle×millésime permettent d'ajuster les paramètres du modèle. Un vecteur de paramètres est défini par couple parcelle×millésime. Ce vecteur représente l'espace commun qui rend les couples parcelle×millésime comparables. Deux stratégies de comparaison sontalors possibles : (i) les comparaisons sont réalisées à partir des paramètres (méthode intensive), ou (ii) les comparaisons sont réalisées à partir de l'estimation de la valeur de la grandeur pour chaque couple parcelle×millésime et chaque unité de temps, commune à tous les couples (méthode extensive).Cette méthode a été appliquée à trois exemples différents.Dans une première application, les climats de différents millésimes intervenus sur différents cépages, entre la floraison et la véraison, ont été comparés entre eux après modélisation des grandeurs de mesure climatiques, à l'aide de modèles très simples.Dans une seconde puis une troisième application, la cinétique d'augmentation du pH et d'accumulation des sucres dans les baies de raisin pendant la maturation a été modélisée sous la forme d'une sigmoïde. Les comparaisons ont ensuite été réalisées en travaillant sur (i) la courbe représentative de chaque cinétique (pH), (ii) les paramètres du modèle (sucres) et (iii) une estimation journalière de la concentration en sucres dans les baies.Les bases de données utilisées dans ces applications proviennent de deux régions très différentes. Des données issues du suivi de la station expérimentale INRA Pech Rouge en Languedoc-Roussillon, dans le sud de la France, ont été utilisées pour l'application 1 et une partie de l'application 3. Des données de suivi de différents domaines de la Napa Valley en Californie ont servi pour l'application 2 et une partie de l'application 3.Le changement d'espace de représentation des données apporte une connaissance nouvelle pour décrire les individus et les phénomènes temporels de la vigne. Cette connaissance pourrait permettre de formaliser un raisonnement par analogies utilisant et valorisant l'expérience passée pour la gestion du millésime en cours. / The initial objective of this thesis is to enhance the in-time follow-up information of the vine, the grape and the environment of the plant stored in traceability databases (BD) traceability to allow comparison between plots and vintages, to a future analogy-based decision support.The work done during this thesis allowed to propose a transformation method for representing sets of asynchronous data in a common space for comparison. This method relies on the expertise of the production system. In this thesis, this method was applied to the comparison of pairs of plot×vintage.The expert knowledge of the vineyard production system allows, in a first phase, to define (i) the general shape of the kinetics of on the vine, the grapes or the plant environment measured grandeurs, and (ii) the effect of the climate on the plant.This expertise is used in a second phase, to propose parametrical models that represent each grandeur kinetic. Monitoring data of each pair plot×vintage are used to adjust the model parameters. A vector of parameters is defined for each pair plot×vintage. This vector represents the common space that makes pairs of plot×vintage comparable. Two comparison strategies are possible: (i) comparisons are made from the parameters (intensive method), or (ii) comparisons are made from the estimation of the value of the quantity for each pair plot×vintage and each time unit, common to all pairs (extensive method).This method was applied to three different examples.In a first application, the climate of different vintages occurred on different grape varieties, between flowering and veraison, were compared with each other after modeling of the measured climate grandeurs, with very simple models.In a second and a third application, the kinetics of the increase of pH and accumulation of sugars in grape berries during ripening was modeled using a sigmoid. Comparisons were then made by working on (i) the graph of each kinetic (pH), (ii) parameters (sugars) and (iii) an estimation of the daily sugar concentration in berries.The databases used in these applications come from two very different winegrowing regions. Data from the monitoring of the INRA Pech Rouge Experimental Station, in Languedoc-Roussillon in the south of France, were used for the application 1 and part of the application 3. Monitoring data from different estates of Napa Valley in California were used for the application 2 and part of the application 3.The change of space where data are represented constitutes a new knowledge that permit one to describe individuals and temporal phenomena of the vine. This knowledge could allow to formalize an analogy-based reasoning that uses and promotes past experience to manage the current vintage.

MÉTODO DE COMPARAÇÕES VISUAIS ENTRE MEDIDAS DE SEGMENTOS COMO FACILITADOR DA APRENDIZAGEM DE CONCEITOS TRIGONOMÉTRICOS

Gonçalves, José Sinval Soares 23 February 2017 (has links)
Made available in DSpace on 2017-07-21T20:56:30Z (GMT). No. of bitstreams: 1 Jose Sinval Soares.pdf: 9600283 bytes, checksum: f7492874195cb7828a5be1c775a62374 (MD5) Previous issue date: 2017-02-23 / It is well the great difficulty presented by the students with respect to the trigonometry. Base on this fact, we understand that any tool that can help in the teaching of this content will always be welcome. The aim of this work is to present a pedagogical proposal that consists of applying a apparently simple method to call a Method of Visual Comparisons. This method consists of obtaining values generated by ratios between measurements of similar figures or even the value of the PI number without having the necessity of measuring and divide using standardized measurement units. Look at the lengths of the segments that represent the sides of triangles, a rectified circumference and your diameter, among others and compare. This comparison starts to check if the measure of a length is greater than, less than or equal to the measure of another length and a more refined, comparison with the fractionation of one of the segments. The main idea is to try to estimate a value, if the measures are equal, if the smaller measure is worth half or perhaps seventy-five percent (three quarters) of the larger, or if the larger is worth two, three, or who knows once and half the smaller measure, only with the look, without dividing numerical values. We believe it's worth measuring, comparing,drawing in scale and measure the scale designed to estimate, because these activities and procedures help in a better understanding of the results that will be demonstrated later / Sabendo das grandes dificuldades apresentadas pelos alunos com relação à trigonometria, entendemos que toda ferramenta que possa auxiliar no ensino deste conteúdo sempre será bem vinda. O objetivo desse trabalho é apresentar uma proposta pedagógica que consiste na utilização de um método aparentemente simples que denominamos Método de Comparações Visuais. Este método consiste em obter valores gerados por razões entre medidas de figuras semelhantes ou mesmo o valor do número PI sem a necessidade de medir e dividir usando unidades padronizadas de medição. Basta observar os comprimentos dos segmentos que representam os lados de triângulos, uma circunferência retificada e seu diâmetro, entre outros e comparar. Esta comparação começa em verificar se a medida de um comprimento é maior, menor ou igual que a medida de outro comprimento e vai até uma comparação mais refinada,com o fracionamento de um dos segmentos. A idéia principal é tentar estimar um valor, se as medidas são iguais, se a medida menor vale metade ou talvez setenta e cinco por cento (três quartos) da maior, ou se a maior vale duas, três, ou quem sabe uma vez e meia a medida menor, apenas com o olhar, sem dividir valores numéricos. Acreditamos ser válida a mensuração, comparação, desenhar em escala e medir na escala desenhada para fazer estimativas, pois estas atividades e procedimentos auxiliam na compreensão dos resultados que serão demonstrados posteriormente.

Acreditação de laboratórios de ensaio e calibração como provedores de ensaios de proficiência sob a norma ISO/IEC 17043

Mianes, Rodrigo Leão January 2016 (has links)
Os ensaios de proficiência têm sido utilizados, por laboratórios de ensaio e calibração acreditados sob a norma ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories), como principal mecanismo para garantia da qualidade de seus resultados. Além de atender a um requisito normativo, a participação satisfatória neste tipo de atividade é utilizada, por organismos acreditadores, como condição à obtenção e manutenção da acreditação. Entretanto, existe uma carência por provedores de ensaios de proficiência acreditados de acordo com a norma ISO/IEC 17043 (Conformity assessment — General requirements for proficiency testing), o que causa dificuldades aos laboratórios. Esta dissertação teve como objetivo analisar a viabilidade de que laboratórios acreditados à ISO/IEC 17025 atuem, simultaneamente, como provedores de ensaios de proficiência, acreditados à ISO/IEC 17043. Para isso, foram estabelecidas as relações entre os itens das normas, identificadas e analisadas as exigências adicionais e adaptações necessárias no sistema de gestão, identificados os potenciais conflitos de interesses e estabelecidas propostas de atendimento para cada item normativo afetado. Os artigos que constituem esta pesquisa foram validados por um grupo de especialistas na área da metrologia, sendo as suas opiniões consideradas nos estudos realizados. Conclui-se, ao final, que a atuação simultânea proposta é viável, exigindo adaptações no sistema de gestão e procedimentos complementares referentes à confidencialidade e à imparcialidade. Como resultado prático, espera-se minimizar a carência por este serviço, sem comprometer sua confiabilidade. / Proficiency tests have been used by testing and calibration laboratories accredited to the ISO/IEC 17025 standard (General requirements for the competence of testing and calibration laboratories) as the main mechanism for assuring the quality of their results. Besides attending to a normative requirement, the satisfactory participation in this kind of activity is used by accreditation bodies as a condition to obtaining and maintaining the accreditation. However, there is a lack of proficiency testing providers accredited according to the ISO/IEC 17043 standard (Conformity assessment — General requirements for proficiency testing), which causes laboratories to have difficulties. This thesis had as its goal to analyze the viability of laboratories accredited to the ISO/IEC 17025 acting simultaneously as proficiency testing providers, accredited to the ISO/IEC 17043. For that, relations between the items of both standards have been established, additional requirements and necessary adaptations in the management system have been identified and analyzed, potential conflicts of interest have been identified and solutions have been proposed for each normative item. A group of experts in the field of metrology validated the articles that constitute this research and their opinions have been considered in the studies. At the end, the conclusion was that the proposed simultaneous acting is viable, requiring adaptations in the management system and complementary procedures referring to confidentiality and impartiality. As a practical result, it is hoped to minimize the shortage for this kind of service, without compromising its reliability.

Comparisons of Snow Deposition, Soil Temperature, Matric Potential and Quasi-friction Velocity Between a Windward Site and a Lee Shelter in a Cold Desert

Neuber, Harvey L. 01 May 1984 (has links)
Regimes of snow depth, soil temperature, soil matric potential and quasi-friction velocity in a windward site and a lee shelter were examined. The differences were analyzed from a biological perspective to .characterize each location in terms of site favorability to plant growth. The chronology of wind and precipitation events was investigated. Snow depth was measured with a system of stakes arranged around and in the interior of a rectangular plot encompassing both a windward site and a lee shelter. Soil temperature, soil matric potential and water potential were measured along a transect which originated in the windward site and terminated in the lee shelter. Soil temperature and water potential were measured by thermocouple psychrometer. Mattie potentials was determined by the pressure-plate method. The regimes of quasi-friction velocity at both ends of the transect were determined by the logarithmic profile method, invoking similarity theory. Wind speed and temperature were measured at two heights in each site. A computer program was used to search the wind and precipitation records and ·categorize and sun the precipitation events by wind direction. The lee shelter exhibited tendencies toward theoretical optima of site favorability. The horizontal distribution of snow maxima was found. to be a function of wind direction at the time of each precipitation event as well as the interaction of wind and the topographical features. Snow was observed to accumulate to a greater depth in the lee shelter than in the windward site. Mean soil temperature over the study period was 8.5° C in the lee shelter while the windward site was 8.0° C. Soil temperature in the lee shelter was never observed to go below 0° C under a snowpack. The range of soil matric potential in the lee shelter was found to be about 14 atm at a depth of 20 cm and about 17 atm at a depth of 50 cm over the summer season. In the windward site the range of soil matric potential was approximately 30 atm at a depth of 20 cm and about 21 atm at a the 50 cm depth over the same period. The lee shelter exhibited lower (less negative) matric potentials than the windward site. These results were not corroborated by the measurement of water potential by thermocouple psychrometers. In the layer from 1.5 to 4.1 m, the mean quasi-friction velocity in the lee shelter was 39 cm s-1, favoring snow deposition there over the windward site where the mean friction velocity was 21 cm s-l. In the 0 m to 1. 5 m layer, mean friction velocity in the windward site was found to be 55 cm s-1.while the lee shelter mean was 48 cm s-1. These results indicate a distinct seperation of flow downwind of the windward site where the lee shelter resides in the turbulent wake of the windward site.

Modeling Time Space Prism Constraints in a Developing Country Context

Nehra, Ram S 31 March 2004 (has links)
Recent developments in microsimulation modeling of activity and travel demand have called for the explicit recognition of time-space constraints under which individuals perform their activity and travel patterns. The estimation of time-space prism vertex locations, i.e., the perceived time constraints, is an important development in this context. Stochastic frontier modeling methodology offers a suitable framework for modeling and identifying the expected vertex locations of time space prisms within which people execute activity-travel patterns. In this work, stochastic frontier models of time space prism vertex locations are estimated for samples drawn from a household travel survey conducted in 2001 in the city of Thane on the west coast of India and National Household Travel Survey 2001, United States. This offers an opportunity to study time constraints governing activity travel patterns of individuals in a developing as well as developed country context. The work also includes comparisons between males and females, workers and non-workers, and developed and developing country contexts to better understand how socio-economic and socio-cultural norms and characteristics affect time space prism constraints. It is found that time space prism constraints in developing country data set can be modeled using the stochastic frontier modeling methodology. It is also found that significant differences exist between workers and non-workers and between males and females,possibly due to the more traditional gender and working status roles in the Indian context. Finally, both differences and similarities were noticed when comparisons were made between results obtained from the data set of India and United States. Many of these differences can be explained by the presence of other constraints including institutional, household, income, and transportation accessibility constraints that are generally significantly greater in the developing country context.

Såld spannmål av kyrkotionden : Priser i Östergötland under Sveriges stormaktstid / Corn sold from church tithes. Prices in Östergötland during Sweden´s period as a great power

Hansson, Göran January 2006 (has links)
<p>The thesis presents annual price series for rye and barley in Östergötland during the period 1592-1735. Prices of wheat, oats, animal products, building materials, iron, nails, horse shoes and horse shoe nails from about the mid-17th century up to 1735 are also presented and analysed. New data has been excerpted from four hospitals and about fifty parishes in Östergötland. Prices from other provinces have also been excerpted for the study. This nes data is compared to already published prices from Sweden´s capital and from several provinces in central parts of the western national region of Sweden of that time. This area constituted Sweden´s core region. By linking the studies results to previous research, a description is made of the price developments for rye, butter and tallow up to 1775, that is, during Sweden´s period of great power and age of freedom. A principal result for the roughly 150 years primarily covered by the thesis is that it was chiefly the prices of rye and barley, the most important food at the time, that fluctuated in twelve cycles. Periodically there were large fluctuatons. The price cycles for corn (half rye, half barley) had an average amplitude of somewhat more than 100 % and a duration of 11 years on average. The prices were on average higher further north in the country. The causes of the price fluctuations are complex. During the major part of the period studied, Sweden was at war or in armistice period, which occupied a large part of the male population. Politically, increasingly great power was gradually concentrated to the king and autocracy was introduced, culminating at the end of Charles XII´s regency. The peasantry was burdened by high taxes and other onuses. After the middle of the 17th century the country was no longer self-subsistent but largely dependent on corn import. The production of foddstuffs decreased, partly through a smaller part of the country´s resources beeing used for production, and partly due to bad harvests. Recurrent epidemics reduced the population even up to the early 18th century.</p>

Subject-Specific Covariates in the Bradley-Terry Model. A Log-Linear Approach

Dittrich, Regina, Hatzinger, Reinhold, Katzenbeisser, Walter January 1996 (has links) (PDF)
The purpose of this paper is to give a log-linear representation of a generalized Bradley-Terry (BT-) Model for paired comparisons which allows the incorporation of ties, order effects, concomitant variables for the objects and categorical subject specific covariates and interactions between all of them. An advantage of this approach is that standard software for fitting log-linear models, such as GLIM, can be used. The approach is exemplified by analysing data from an experiment concerning the ranking of European universities. (author's abstract) / Series: Forschungsberichte / Institut für Statistik

Modern Mathematical Methods In Modeling And Dynamics Ofregulatory Systems Of Gene-environment Networks

Defterli, Ozlem 01 September 2011 (has links) (PDF)
Inferring and anticipation of genetic networks based on experimental data and environmental measurements is a challenging research problem of mathematical modeling. In this thesis, we discuss gene-environment network models whose dynamics are represented by a class of time-continuous systems of ordinary differential equations containing unknown parameters to be optimized. Accordingly, time-discrete version of that model class is studied and improved by using different numerical methods. In this aspect, 3rd-order Heun&rsquo / s method and 4th-order classical Runge-Kutta method are newly introduced, iteration formulas are derived and corresponding matrix algebras are newly obtained. We use nonlinear mixed-integer programming for the parameter estimation and present the solution of a constrained and regularized given mixed-integer problem. By using this solution and applying the 3rd-order Heun&rsquo / s and 4th-order classical Runge-Kutta methods in the timediscretized model, we generate corresponding time-series of gene-expressions by this thesis. Two illustrative numerical examples are studied newly with an artificial data set and a realworld data set which expresses a real phenomenon. All the obtained approximate results are compared to see the goodness of the new schemes. Different step-size analysis and sensitivity tests are also investigated to obtain more accurate and stable predictions of time-series results for a better service in the real-world application areas. The presented time-continuous and time-discrete dynamical models are identified based on given data, and studied by means of an analytical theory and stability theories of rarefication, regularization and robustification.
