Le déséquilibre et le désordre du réel ont modifié chez l’homme baroque la vision de son être; leur présence écarte la gratuité de ses actes. Ses fascinations sont des indices révélateurs, ses rejets et ses attachements représentent des témoignages et des messages à déchiffrer. Notre étude essaie d’expliquer les raisons de la fascination de la génération baroque pour l’élément liquide à travers l’examen de l’imaginaire de ses aspects dans l’oeuvre baroque. L’imaginaire ou ce que Gilbert Durand appelle ‘’le capital pensé’’ de l’homme est une entité stratifiée dans la durée, plusieurs facteurs participent à sa structuration. Par conséquent, son examen exige une approche pluridisciplinaire et interdisciplinaire. Grâce aux sciences cognitives qui représentent la voie par laquelle passe l’avenir des recherches sur l’imaginaire selon Philippe Walter, la présente étude essaie d’éclairer l’Imaginaire baroque à travers l’examen de la valeur de l’élément de l’eau dans des textes publiés entre 1580 et 1640. Notre travail utilise quatre des six sciences cognitives qui sont désignées par Georges A. Miller et qui instaurent à travers leurs corrélations des domaines interdisciplinaires. Pour explorer les représentations de cet élément dans le texte baroque avec un objectif qui consiste à leur proposer des explications causales sont indispensablement mobilisées l’anthropologie, la philosophie, la psychologie, et la linguistique. L’imaginaire baroque est reconstitué dans notre recherche grâce aux 5 croisements établis entre les sciences précédentes et les disciplines de l’histoire de l’art, de la critique littéraire, du folklore, de l’ethnologie, de la mythologie, de la sociologie, et de l’histoire des religions. Notre travail examine l’un des aspects de la nature dans l’imaginaire baroque. A travers nos analyses, nous essayons de retracer l’être et l’existence de l’homme baroque grâce aux présences de l’un de leurs constituants dans l’oeuvre de ce dernier. L’élément de l’eau est ce constituant qui représente l’un des aspects de la nature. La problématique dans notre travail, est composée d’un volet qui porte sur la valeur de l’élément de l’eau dans l’oeuvre baroque. Il y a un second volet visant à prouver que l’examen de l’imaginaire représente un outil permettant de cerner les reliefs et les complexités d’un texte baroque et un texte ayant une structure similaire avec celle que possède ce dernier, c’est-à-dire une structure incohérente et non linéaire. Notre recherche aimerait proposer une lecture de l’imaginaire de la matière dans le texte baroque et dans le texte littéraire en général. Elle aimerait démontrer que l’examen distant et interactif des actes de l’homme aide à leur trouver des explications; et que l’examen de l’imaginaire d’une oeuvre qui représente un acte de l’imaginaire de l’homme, aide à cerner ses implicites, les raisons de sa création, et la psychologie qui a dominé les circonstances de sa production. / The imbalance and the chaos in which Baroque man lived, changed his vision of his entourage and at the same time they excluded the gratuitousness of his actions. His fascinations are messages to be deciphered, his rejections and attachments represent revealing clues and testimonials. Our study tries to explain the reasons of the fascination of the baroque generation for the liquid element through the examination of the imaginary of its aspects in the baroque work. The imaginary or what Gilbert Durand calls "thought capital" of man is a hybrid organism, several factors participate in its structuring therefore its examination requires an interdisciplinary approach. Through cognitive science, that represent the future of research on the imagination according to Philippe Walter, this study tries to illuminate the Baroque Imagination through the examination of the value the element of water in the works published between 1580 and 1640. Our work uses four of the six cognitive sciences which are designated by Georges A. Miller and which establish interdisciplinary fields through their correlations. To explore the representations of this element with the Anthropology, philosophy, psychology, and linguistics are indispensable to the objective of offering them causal explanations. The baroque imagination is reconstituted in our work by combining these sciences with the disciplines of the history of art, literary criticism, folklore, ethnology, mythology, sociology, and the history of religions. Our work examines one of the aspects of nature in the baroque work. Through our analyzes we try to trace the being and the existence of baroque man through the manifestations of one of their components in the work of the latter. The element of water which is this component and it represents one of the aspects of nature. The problematic in our work is composed of a component that deals with the value of the element of water in the baroque work. The second part aims to prove that the 7 examination of the imaginary represents a tool that helps to identify the reliefs of a baroque text and a text with a similar structure with the latter, that is to say an incoherent structure and complex. Our research proposes a reading for the imaginary of the material in the literary text. Our study would like to demonstrate that distant and interactive examination of human acts and his works serves to identify their explanations; and that the examination of the imaginary of a work which represents an act of the imaginary of man serves to identify its implicit and the reasons for its creation, and the psychology that dominated the circumstances of its production.

Este trabalho tem como propósito examinar o efeito da representação gráfica do tempo como meio para facilitar a construção de um esquema mental capaz de acomodar os usos do Present Perfect e de seu contraste com o Simple Past em um módulo de língua inglesa mediado por computador. O Present Perfect constitui-se, reconhecidamente, em um problema para professores e alunos de língua inglesa. Dowty (1979) observa que, “com exceção do progressivo, nenhum outro tempo da língua inglesa recebeu mais atenção dos lingüistas do que o Present Perfect e mesmo assim não há um consenso geral no que se refere à sua estrutura semântica.” Dois estudos foram realizados (2003 e 2005) nos quais os participantes foram distribuídos aleatoriamente em uma de duas condições experimentais: (1) Somente texto e (2) Texto+Gráficos. No segundo estudo foram incorporados gráficos interativos, seguindo a recomendação de Peeck (1993) e o princípio de interatividade de Mayer (2002). Os dados coletados através de um pré-teste, pósteste imediato e pós-teste deslocado, foram analisados através de análises de variância (ANOVAs) de um fator e análises de variância para medidas repetidas. Os resultados das ANOVAs, aliados às respostas de um questionário aplicado logo após o pós-teste imediato sugerem que os tratamentos tiveram pouca influência na compreensão e retenção de informações a curto prazo; o princípio de fatiamento de Sweller (1988), utilizando o modelo temporal de Declerck (1986) e o modelo aspectual de Godoi (1992), aliado com o princípio de multimídia da teoria de aprendizado por multimídia de Mayer (2002), mostraram-se eficazes na compreensão e retenção a longo prazo dos usos e contrastes entre o Present Perfect e o Simple Past; e a inclusão de gráficos interativos no estudo de 2005, serviu para diminuir a confusão causada pelos gráficos estáticos, ocorrida no estudo de 2003. / The present study examined the effect of graphical representation of time in facilitating both interpretation and construction of schemata capable of accounting for the uses of the Present Perfect and its contrast with the Simple Past in an English intermediate course mediated by computer. The English Present Perfect is a wellknown troublemaker for EFL/ESL teachers and learners. Dowty (1979) observes that, “aside from the progressive, no English tense has received more attention from linguists and yet eluded a convincing analysis so completely as the Present Perfect.” Two studies were carried out (2003 and 2005) in which the students were randomly distributed between two treatments: (1) Text only and (2) Text+Graphics. In the second study, interactive graphics were added, following Peeck’s (1993) advice to improve active learning and Mayer’s (2002) interactivity principle to give students more control over the material. The data collected in the pre-test, immediate post-test and delayed post-test were analyzed through analyses of variance (ANOVAs) of one factor and repeated measures ANOVAs. The results of the ANOVAs, together with the answers of the questionnaire applied right after the immediate post-test, suggest that the treatments had low influence over the comprehension and retention of information for the immediate post-test; Sweller’s (1988) chunking principle, utilizing Declerck’s (1986) temporal model and Godoi’s (1992) aspectual model, allied with Mayer’s (2002) principle of multimedia, were effective to promote long lasting comprehension and retention of the uses of the Present Perfect and its contrast with the Simple Past; the inclusion of interactive graphics in the second study (2005), was effective to diminish the confusion caused by the static graphics utilized in the first study (2003).

O trabalho contextualiza historicamente, descreve e discute características de um possível perfil cognitivo dos engenheiros, atualizando-o em relação às necessidades da sociedade e da cultura contemporâneas, com base no paradigma multidisciplinar das Ciências Cognitivas, apresentado a partir da obra Como a mente funciona, de Steven Pinker, e em pesquisa bibliográfica sobre autores da área de Engenharia. Busca analisar criticamente as necessidades do ensino contemporâneo de Engenharia, identificando estratégia didáticopedagógica compatível com as características descritas no perfil. A elaboração didática de projetos foi a estratégia escolhida, por apresentar a mesma estrutura cognitiva (raciocínios, operações mentais, comportamentos, atitudes e posturas) da atividade profissional, bem como por caracterizar um contexto integrado de conceitos teóricos, atividades práticas, tomadas de decisão e vivências que deverão constituir um apoio à consolidação da memória de longa duração dos alunos, e, por conseguinte, de seu aprendizado, segundo conceitos apresentados por Roger Schank na obra Dynamic Memory Revisited. O trabalho se desenvolve com a escolha de um modelo de curso à distância estruturado a partir do mesmo paradigma, para aplicar a estratégia escolhida. Trata-se do modelo e-learning-by-doing, apresentado por Roger Schank na obra Designing world-class e-learning. São descritas atividades de planejamento, implantação e análise qualitativa de resultados de um curso-piloto à distância (com o referido modelo), de elaboração didática de um projeto de Engenharia Geotécnica, com alunos de mestrado do Pós-Graduação em Engenharia Civil, da Universidade Federal do Rio Grande do Sul, sob coordenação do prof. Fernando Schnaid. A experiência teve excelente receptividade e aproveitamento dos alunos. O framework teórico-conceitual multidisciplinar mostrou-se enriquecedor, apontando possibilidades de continuidade da pesquisa sobre ensino de Engenharia, relacionadas ao aprofundamento do perfil dos engenheiros, ao uso didáticopedagógico de projetos e ao modelo e-learning-by-doing, todos eles com aplicação na prática docente e na formação de professores. O trabalho constituiu pesquisa para obtenção do título de doutor, no Programa de Pós-Gradução em Informática na Educação (PPGIE) da Universidade Federal do Rio Grande do Sul (UFRGS), na linha de pesquisa Paradigmas para a Pesquisa sobre Ensino Científico e Tecnológico. / This work describes and discusses engineering profile from historical, cultural and cognitive perspectives, in an attempt to fit contemporary needs based on the multidisciplinary paradigm of Cognitive Sciences. Emphasis is given to Steven Pinker’s book How the mind works and other bibliographic research reported within the Engineering domain. Needs of contemporary Engineering education are analyzed, choosing a pedagogical strategy compatible with the described profile. Didactic project making was the chosen strategy - it comprises the same cognitive structure of the professional activity, including way of thinking, mental operations, behavior, attitude and states of mind. It can also be seen as a theoretical, practical, decision making and living context that supports long term memory consolidation and, as a consequence, supports the activity of learning, following ideas presented by Roger Schank’s book Dynamic Memory Revisited. The work follows a distance learning course based on the same cognitive paradigm chosen to represent the adopted model and strategy. The strategy is based on e-learning-by-doing model introduced by Roger Schank’s book Designing world-class e-learning, which is adopted to plan and to implement an experimental distance course for a project on Geotechnical Engineering, to masters students from the Civil Engineering Graduation Program at Federal University of Rio Grande do Sul, coordinated by professor Fernando Schnaid. The experience is reported and results are qualitatively analyzed with excellent responses from students in both participation and performance. Theoretical and conceptual multidisciplinary frameworks proved to be a reach framework to present and future research related to Engineering education, engineering profile, didactic use of projects adopting the e-learning-by-doing model. This concept can be applied to graduate and undergraduate courses and to teachers´ continuous education. The work is part of the requirements designed to obtain a PhD degree at the Informatics applied to Education Graduation Program (PPGIE), from Federal University of Rio Grande do Sul (UFRGS), Brazil, in the research line of “Paradigms for the Research on Scientific and Technological Education”.

Este trabalho aborda o desenvolvimento e implementação de um Sistema Tutor Inteligente (STI), disciplina da Inteligência Artificial, disponibilizado para acesso pela World Wide Web e modelado para o domínio da Engenharia de Fundações. No planejamento desse STI optou-se pela implementação da estratégia pedagógica baseada em elaboração de projeto (Project-Based Learning - PBL), atividade que, supõe-se, contém a síntese das habilidades desejadas para o profissional da área das Engenharias. A elaboração de projetos pressupõe o diagnóstico das condições iniciais do problema a ser resolvido, o equacionamento e a síntese de conhecimento necessária para propor soluções viáveis, características que evidenciam a complexidade da ação de projetar e vêm ao encontro das necessidades complexas do ensino de Engenharia. Este tema integra o framework teórico desta Tese. Nele contextualiza-se o problema da formação do engenheiro contemporâneo, destacando-se as estratégias de raciocínio necessárias para a análise, equacionamento e proposição de soluções para problemas rotineiros no exercício profissional. Estes pressupostos são estruturados em um STI que envolve o uso de recursos computacionais com a intenção de simular a tutoria humana.

A estrutura interna do STI, bem como a interface, foram desenvolvidas para que o sistema tivesse condições de acompanhar o aluno durante a solução dos problemas propostos e, desta forma, inferir sobre o nível de conhecimento e aspectos do raciocínio do aluno, habilitando o sistema a agir de acordo com as estratégias implementadas. / The present work aims at developing and implementing a Intelligent Tutoring System in the field of Foundation Engineering, (ITS), a subject of Artificial Intelligence, available from World Wide Web. In the design of this system, a pedagogical strategy defined as Project-Based Learning (PBL) was adopted as a framework given the fact that it is thought to encompass all needs that are necessary in the Engineering profession. Engineering design comprises diagnosis of the boundary conditions of a problem, equation of all the intervenient factors affects its performance and a synthesis of all theoretical concepts related to the Field of knowledge, a set of characteristics that highlight the complexity associated to engineering science that should be necessarily incorporated to engineering learning and education. This frame of reference has been incorporated in the ITS, in a computation environment structured to emulate human tutorial experience. To enhance learning, the system incorporates a number of essential features: a robust model of domain that represents the knowledge of an specialist in foundation engineering, an interface capable of emulating a learning environment that relates the student to this background knowledge, a set of pedagogical schemes that are able to identify the student understanding at every step taken during the solution of case studies. A database containing a variety of multimedia sources on the subject can be accessed at any time to help students in receiving theoretical and practical information required to the solution of the problem. The ITS contains a series of case studies constructed in various levels of complexity implement to enforce students to identify the variables that are associated to each design problem. The internal structure of the system and its interface have been conceived to allow a continuous interaction with the student, capturing his understanding, identifying his needs and given assessment to theoretical information, all in line with the knowledge of the specialist and within the pedagogical implemented strategies.

The purpose of this thesis is to critically examine how W.V. Quine, Michael A. Bishop and J.D. Trout confront the normativity objection against naturalized epistemology. In Chapter One, normativity in epistemology is introduced, followed by a brief look over Quine’s grievances against the traditional approach to epistemology. Quine rejects traditional epistemology and assimilates epistemology with science. The second chapter assesses how Quine naturalizes epistemology, and the third chapter evaluates his engineering response against the normativity objection. Bishop and Trout’s theory, founded upon the Aristotelian Principle, concentrates on reasoning and epistemic excellence instead of belief justification. Strategic Reliabilism’s attempt to dissolve the naturalistic challenge and resolve the normativity objection is inspected in Chapter Four. The final chapter, succinctly, summarizes its preceding chapters and ends by suggesting a closer exploration of the link between epistemology and cognitive sciences, to better understand the underlying mechanics of the objections that face naturalized epistemology. / Graduate / 0422 / 0621 / soushi@gmail.com

<p>Due to the great transitions and turmoil uniquely attributed to the period of adolescence, youth experience a greater risk for substance use and the multitude of concerns that coincide with the early onset of substance use. Many biological and environmental factors have been investigated as predictors of adolescent substance use. Executive function and disruptive behaviors are two important individual characteristics linked to adolescent substance use. Both smoking during pregnancy and sibling relationships are separate contexts that can mitigate or exacerbate the associations of executive function and adolescent substance use. The present study focuses on development of substance use through executive function deficits and disruptive behavior, while considering smoking during pregnancy and sibling relationships as unique moderators of these pathways. This work addresses a novel, interrelated set of questions with a series of three studies. The central hypothesis driving this program of research is that smoking during pregnancy and sibling relationships are under-studied contexts that can mitigate or exacerbate the associations of executive function, disruptive behavior, and adolescent substance use. This dissertation examines whether: (1) executive function mediates the smoking during pregnancy-disruptive behavior association and smoking during pregnancy exacerbates the executive function-disruptive behavior association, (2) smoking during pregnancy exacerbates the association between executive function and disruptive behavior during adolescence using a sibling comparison design, and (3) sibling relationship quality moderates developmental trajectories of executive function on the transition from disruptive problems to adolescent substance use using a high-risk, longitudinal sample. Findings challenge the link between exposure to smoking during pregnancy and both executive function and disruptive behavior. Further, these findings reinforce the need to utilize genetically-informed designs when examining potential effects of smoking during pregnancy. Additionally, this dissertation found support for the link between executive function and disruptive behavior, but not executive function and substance use. </p>

<p>Cognitive control is accomplished by a set of higher-order cognitive processes that are recruited to aid in the completion of various tasks. A popular proposed mechanism is the Dual Mechanisms of Control (Braver, Gray, & Burgess, 2007), proposing proactive and reactive mechanisms. While neuroscience studies provide evidence that these are two distinct processes, it remains unclear whether the processes are competing, or whether they can be used together. That is, are the two processes able to both be enacted to some degree? Further, whether these mechanisms can be titrated to produce a gradient-like use of control on a trial-level basis is unknown. These are the two primary pursuits of this dissertation. Experiment 1 shows the titrated pattern of control use, indicating (a) sensitivity to task demands, and (b) dynamic use of proactive and reactive control at the trial level, in a new task. Further, a novel contribution is the observation of ability to titrate the use of control. Additional experiments relate performance on this task to working memory (Experiment 2), replicate the findings in an online format (Experiment 3), and differentiate performance from distance effects commonly seen in relative judgment tasks (Experiment 4). This work has implications for the understanding of how cognitive control functions and how dynamically the use of these mechanisms can be adjusted.</p>

<div>Haptic interfaces possess great potential for both transmitting information and affecting emotion. I present two studies exploring these two applications.</div><div><br></div><div>The first study investigates the ability to selectively attend to certain tactile stimuli while ignoring others. Understanding this ability is necessary when designing vibrotactile displays that present multiple simultaneous signals for information transmission. Participants in this study wore a tactile display on each arm. They were trained to identify nine stimuli varying in location and frequency and tested on stimulus identification under various conditions, depending on whether one or both arms were stimulated and whether one or both arms were attended to. The results provide empirical evidence for selective attention of vibrotactile stimuli and indicate that participants can selectively attend to three locations and two frequencies with high accuracy.</div><div><br></div><div>The second study explores whether haptics can enhance the perceived immersiveness, novelty, and creepiness of a haunted house. Vibrotactile stimuli inspired by natural phenomena were presented to the user’s palm, and concealed actuators rattled the user’s chair. Séance-themed audio and visuals provided narrative context. In a post-experience questionnaire, nineteen of twenty-two participants reported that haptic effects increased their sense of immersion. A follow-up experiment was conducted to compare the impact of using multiple, distinct haptic stimuli as opposed to repeating a single,</div><div>multiplex stimulus. The results demonstrate both the influence of context on stimulus interpretation, as well as the unique payoffs when stimuli are tailored for a particular context.</div>

The ability to solve problems creatively has been crucial for the adaptation and survival of humans throughout history. In many real–life situations, cognitive processes are not isolated. Humans are social, they communicate and form groups to solve daily problems and make decisions. Therefore, the final output of cognitive processes can come from multi–brains in groups rather than an individual one. This multi–brain output can be largely different from the output that an individual person produces in isolation. As a result, it is essential to include team–level processes in cognitive models to make a more accurate description of real– world cognitive processes in general and problem solving in particular. This research aims to answer the general question of how working in a team affects creative problem solving. For doing that, first, we propose a computational model for multi-agent creative problem solving. Then, we show how the model can be used to study the factors that are involved in creativity in teams and potentially will suggest answers to questions such as, ‘how team size is related to creativity’.

The goal of my dissertation is to take a step toward shifting the narrative in engineering from “surviving” to “thriving” so that more engineering students can reach their full potential in college and beyond. Many engineering students experience barriers such as the hardships of engineering culture, which are exacerbated for women and underrepresented racial/ethnic minorities(such as Black, Latinx, and Indigenous students). These barriers are well documented in research and well discussed in interventions to support engineering student success, under the assumption that helping students cope with these cultural and systemic barriers will, by itself, lead to their success. My research on engineering thriving challenges this assumption by asserting that the skills engineering students need to succeed academically, socially, and personally differ from the skills they need to “survive” cultural and systemic barriers.<br><div><br></div><div>This dissertation employs an exploratory multiphase research design, with three studies, to develop a model of thriving for undergraduate engineering students. The first study consists of a scoping literature review of 68 papers to define and characterize engineering thriving as the process in which engineering students develop and refine competencies that allow them to function optimally in engineering programs. From this definition, the second study employs a Delphi process with 47 experts to develop a model of engineering thriving that includes 1) internal thriving competencies; 2) external thriving outcomes; 3) engineering culture, systemic factors, resources, context and situation; and 4) how these three broader categories function together. The third study tests some of these relationships proposed in the model of engineering thriving using structural equation modeling(SEM) on a large dataset of responses by over 2,000 undergraduate U.S. engineering students to a survey that measured various constructs associated with thriving. Findings from the SEM analysis suggest that gratitude was one of the most important competencies for engineering student thriving, and that a holistic model approach accounted for 79% of the variance in engineering students’ belongingness and 25% of the variance in perceptions of faculty caring(two external thriving outcomes).<br></div><div><br></div><div>Understanding and supporting more engineering thriving has positive implications for students, recruitment and outreach, and engineering programs. Thriving is multidimensional and, thus, supporting engineering students to achieve traditional success metrics (such as academic performance and graduation) goes hand in hand with supporting their personal and social development and wellbeing. Recruitment and outreach of K-12 students can benefit from viewing engineering as an attractive and inspirational career, combating negative stereotypes that currently deter students from pursuing engineering. Engineering programs can benefit from developing a reputation and culture of thriving. However, cultural change requires the collective investment from all members of the engineering community.<br></div>
