O objetivo é verificar o quanto essas representações distam, ou se aproximam, dos estereótipos femininos construídos ao longo da civilização ocidental. O corpus da pesquisa é formado por três publicações de editoras consolidadas no mercado brasileiro: Nova e Lola (já extinta), da Editora Abril, e Marie Claire, da Editora Globo, colecionadas por seis meses – de janeiro a junho de 2013. A fundamentação teórica inclui trabalhos de estudiosos do feminismo, da história das mulheres no mundo ocidental, da identidade como construção narrativa, das interações sociais e da comunicação. A Análise de Conteúdo categorial, como proposta por Laurence Bardin, foi a metodologia usada para analisar o material selecionado. Procedeu-se ainda a uma pesquisa de recepção com leitoras das respectivas revistas, cujo objetivo é averiguar a sua percepção relativa a esse produto. A pesquisa aponta para a ideia de “modernizar para não transformar” - característica encontrada nas revistas e acentuada nas últimas décadas. / The purpose of this dissertation is to identify different forms of female sexuality representation in contemporary Brazilian magazines aimed at female audiences. The specific aim is to verify how much these representations get close or far from long-standing feminine stereotypes built in Western civilization. The research corpus is composed of three publications by some traditional Brazilian printing houses: the Nova and Lola magazines (the last one already extinct) by Editora Abril and Marie Claire by Editora Globo, collected along six months – from January through June 2013. Theoretical fundamentals used in this work include results of research about feminism, the history of women in the Western world, identity as a narrative construction, social interactions and communication. Categorical content analysis, as a proposal by Laurence Bardin was the methodology used to analyze the selected material. A research work about the reception of this product has also been conducted. The overall conclusion suggests the existence of an idea of “modernizing in order not to transform” a characteristic that has been found in magazines and seems to have been highlighted in the last decades.

La thèse poursuit comme objectif d’explorer la liaison entre le projet de paysage, conçu comme une intention de transformation soit matérielle soit immatérielle du territoire, en relation à la pratique photographique. Il s’agit d’une enquête interdisciplinaire qui essaie de comprendre les interactions possibles entre les deux matières, évitant une soumission de l’une à l’autre. Se matérialise un champ de recherche sur la culture du projet, orienté à déterminer les possibilités d’utilisation de la photographie comme contribution aux pratiques de conception de l’espace. L’étude problématique pose les questions suivantes: La photographie en tant que représentation et interprétation critique, joue-t-elle un rôle dans le processus matériel et immatériel de transformation du territoire? Quel est l’impact/l’influence sur la pensée projective d’une pratique de fragmentation sélective du paysage? Un mécanisme de re-production du réel, tel que la photographie, peut-il proposer une manière tangible de concevoir l’espace?Pour répondre à cette problématique la recherche développe une démarche méthodologique qui souhaite combiner un double niveau d’étude. D’un côté le parcours de connaissance générale, interrogeant le statut de la photographie en relation au paysage, au-delà d’une simple catégorisation d’un genre photographique. De l’autre côté une pratique expérimentale de l’action photographique dans le cadre d’une transformation de la côte du Sulcis Iglesiente, en Sardaigne: une tentative de représentation critique du territoire. La reconstruction d’une image du territoire passe par une prise de conscience et une mise en perspective de son évolution. L'intérêt général est de pouvoir construire la notion de « vision paysagère » comme action de voir spécifique, évitant la formation des stéréotypes ; une pratique capable de proposer un regard interprétative sur le paysage à travers le filtre de l’appareil photographique. / The thesis aims at exploring the relationship between the landscape project, conceived as a discipline able to transform the material and immaterial territory, and the photographic practice . It is an interdisciplinary research that attempts to understand the possible interactions between the two branches of knowledge, avoiding the submission of one over the other. It is so conceived a field of research on the design culture oriented to determine the potential use of photography as a contribution to the conception of space. The study highlights some key issues: Can the photography, as representation and critical interpretation, perform a role in the process of transformation of the material and immaterial territory? What is the influence of a practice of selective fragmentation of the landscape on the design thinking? May a mechanism of reproduction of the reality propose a concrete way of conceiving the space?In order to answer these questions the research developed a methodology oriented to the combination of two levels of study. On the one hand the creation of a broad knowledge which examines the status of the photography in relation to the landscape, going beyond the simple categorization of a photographic genre. On the other hand an experimental practice of photographic action in the context of the coastal landscape of the Sulcis-Iglesias, in Sardinia. It is an effort aimed at a critical representation of the territory. The aim is to build a concept of vision paysagère, as a specific visual action, which avoids the formation of stereotypes. A practice able to offer an interpretative view on the landscape.

This research investigates soil respiration (Rs) in a boreal jack pine (Pinus banksiana Lamb.) fire scar chronosequence at Sharpsand Creek, Ontario, Canada. During two field campaigns in 2006 and 2007, Rs was measured in a chronosequence of fire scars in the range 0 to 59 years since fire. Mean Rs adjusted for soil temperature (Ts) and soil moisture (Ms) (Rs T,M) ranged from 0.56 μmol CO2/m2/s (32 years post fire) to 8.18 μmol CO2/m2/s (58 years post fire). Coefficient of variation (CV) of Rs adjusted for Ts and Ms ranged from 20% (16 years post fire) to 56% (58 years post fire). Across the field site, there was a significant exponential relationship between Rs adjusted for soil organic carbon (Cs) and Ts (P = 1.24*10-06; Q10 = 2.21) but no effect of Ms on Rs adjusted for Cs and Ts for the range 0.21 to 0.77 volumetric Ms (P = 0.702). Rs T,M significantly (P = 0.030) decreased after burning mature forest, though no significant (P > 0.1) difference could be detected between recently burned and unburned young forest. Rs was measured in recently burned boreal jack pine fire scar age categories that differed in their burn history and there was a significant difference in Rs T,M between previously 32 v 16 year old (P = 0.000) and previously 32 v 59 year old (P = 0.044) scars. There was a strong significant exponential increase in S R T,M with time since fire (r2 = 0.999; P = 0.006) for the chronosequence 0, 16 and 59 years post fire, and for all these age categories, Rs T,M was significantly different from one another (P < 0.05). The Joint UK Land Environment Simulator (JULES) was used to model vegetation re-growth over successional time at Sharpsand Creek, though it appeared to perform poorly in simulating leaf area index and canopy height. JULES probably over estimated heterotrophic Rs at Sharpsand Creek when Ts corrected simulated values were compared with measured Rs T,M. The results of this study contribute to a better quantitative understanding of Rs in boreal jack pine fire scars and will facilitate improvements in C cycle modelling. Further work is needed in quantifying autotrophic and heterotrophic contributions to soil respiration in jack pine systems, monitoring soil respiration for extended time periods after fire and improving the ability of JULES to simulate successional vegetation re-growth.

Considérant un point de vue général de cette thèse aborde le problème de trouver, à partir d'un ensemble de blocs de construction, un sous-ensemble qui procure une solution à un problème donné. Ceci est fait en tenant compte de la compatibilité de chacun des blocs de construction par rapport au problème et l'aptitude d'interaction entre ces parties pour former ensemble une solution. Dans la perspective notamment de la thèse sont les blocs de construction de méta-modèles et le problème donné est une description d'un problème peut être résolu en utilisant un logiciel et d'être résolu en utilisant un système multi-agents. Le noyau de la proposition de thèse est un processus qui analyse un problème donné et puis il proposé une solution possible basée sur système multi-agents pour ce problème. Il peut également indiquer que le problème ne peut être résolu par ce paradigme. Le processus adressée par la thèse consiste en les étapes principales suivantes: (1) A travers un processus de caractérisation on analyse la description du problème pour localiser le domaine de solutions, puis choisissez une liste de candidats des méta-modèles. (2) Les caractérisations de méta-modèles candidats sont prises, ils sont définis dans plusieurs domaines de la solution. On fait la chois parmi le domaine trouvé dans la étape précédant. (3) On crée un système multi-agents où chaque agent représente un candidat méta-modèle. Dans cette société les agents interagissent les uns avec les autres pour trouver un groupe de méta-modèles qui est adapté pour représenter une solution donnée. Les agents utilisent des critères appropriés pour chaque méta-modèle à représenter. Il évalue également la compatibilité des groupes créés pour résoudre le problème de décider le groupe final qui est la meilleure solution. Cette thèse se concentre sur la fourniture d'un processus et un outil prototype pour résoudre plutôt la dernière étape de la liste. Par conséquent, le chemin proposé a été créé à l'aide de plusieurs concepts de la méta-analyse, l'intelligence artificielle de coopération, de la cognition bayésienne, incertitude, la probabilité et statistique. / From a general point of view this thesis addresses an automatic path to build a solution choosing a compatible set of building blocks to provide such a solution to solve a given problem. To create the solution it is considered the compatibility of each available building block with the problem and also the compatibility between each building block to be employed within a solution all together. In the particular perspective of this thesis the building blocks are meta-models and the given problem is a description of a problem that can be solved using software using a multi-agent system paradigm. The core of the thesis proposal is the creation of a process based on a multi-agent system itself. Such a process analyzes the given problem and the available meta-models then it matches both and thus it suggests one possible solution (based on meta-models) for the problem. Nevertheless if no solution is found it also indicates that the problem can not be solved through this paradigm using the available meta-models. The process addressed by the thesis consists of the following main steps: (1) Through a process of characterization the problem description is analyzed in order to locate the solution domain and therefore employ it to choose a list of most domain compatible meta-models as candidates. (2) There are required also meta-model characterization that evaluate each meta-model performance within each considered domain of solution. (3) The matching step is built over a multi-agent system where each agent represents a candidate meta-model. Within this multi-agent system each agent interact with each other in order to find a group of suitable meta-models to represent a solution. Each agent use as criteria the compatibility between their represented candidate meta-model with the other represented meta-models. When a group is found the overall compatibility with the given problem is evaluated. Finally each agent has a solution group. Then these groups are compared between them in order to find the most suitable to solve the problem and then to decide the final group. This thesis focuses on providing a process and a prototype tool to solve the last step. Therefore the proposed path has been created using several concepts from meta-analysis, cooperative artificial intelligence, Bayesian cognition, uncertainty, probability and statistics.

El mantenimiento de la vía se ha convertido en los últimos años en un tema verdaderamente relevante para la ingeniería ferroviaria debido a la necesidad de conseguir mejores niveles de calidad a menores costes. Para ello, no hay más remedio que incorporar a las filosofías y procedimientos tradicionales del mantenimiento y la auscultación de la vía nuevas técnicas, que en muchos casos están ampliamente desarrolladas en otros campos de la ingeniería. Así, este trabajo profundiza en las técnicas de adquisición y procesado de datos para su aplicación a la auscultación de la vía. Para ello, se han realizado varias pruebas en la red de Metro de Valencia, registrando las aceleraciones producidas en las cajas de grasa durante la circulación de los vehículos por las vías. Dichas aceleraciones se han registrado y analizado de diferentes maneras, variando la frecuencia de muestreo, la frecuencia de filtrado, el emplazamiento de los acelerómetros y los diferentes parámetros que definen las representaciones tiempo-frecuencia. Los resultados muestran los valores óptimos de los parámetros que determinan la auscultación dinámica y el mejor emplazamiento para los acelerómetros. Además, mediante el análisis espectral y los diagramas tiempo-frecuencia es posible identificar y clasificar los diferentes defectos, puntos singulares y modos de vibración de la vía. De este modo, pueden sentarse las bases para la aplicación de técnicas de procesado digital de imágenes al mantenimiento de la vía. / Salvador Zuriaga, P. (2014).
