Da mesma forma, coloca também em evidência a premente necessidade de que o processo escolar de ensino-aprendizagem da produção de texto como um todo (e da sua dimensão ideativa em particular) seja efetivado dentro do enfoque sócio-histórico, articulando-se a perspectiva enunciativa bakhtiniana com os construtos vygotskianos, sob a égide de uma efetiva mediação docente, centrada na pedagogia dos projetos e na conseqüente intertransdisciplinaridade, de modo a permitir ao educando construir, dialógica e dialeticamente, não somente o seu conhecimento de mundo, mas, principalmente, a sua consciência crítica (os seus valores) e a sua forma de atuar no mundo (as suas atitudes). / On starting from the assumption that textual production abilities must necessarily involve a three-legged language support that are linguistic or grammatical dimension, interactive dimension and mental one (such a dimension that enlarges itself proportionately people increment their school time) this research define his goals on characterizing students textual performance by analyzing their wrote productions. As a conclusion, we have found that failure of school textual production learning is due to the omission or failure of a systematic mental dimension language teaching. In the same way, it puts in evidence that full textual production teaching-learning process (and mental dimension in particular) be done in according to historical-social theories, by connecting the bakhtinian enunciatively perspective with vygotskian theoretical constructs, both perspectives realized under effective docent intermediations focused in Project Methodology and in its derivate intertransdisciplinarity principles in order to allowing students to achieve, in a dialogical and dialectical way, not only their knowledge but also their critical conscience and their proper manner of acting in life.

Fundação de Amparo a Pesquisa no Estado do Rio Grande do Sul / The study of individuals and behavior is not new in Economics and crosses different schools of thought. Approaches that reinforce the criticisms of Neoclassical traditional conceptions of isolated and cognitively perfect individual bring contributions from other sciences, such as Psychology, Sociology and Philosophy. By analyzing the behavior, you need to consider the elements that make up individuals: cognition - the processes of the human mind - and institutions - the instincts and habits. So, how to build an analytical base that considers individuals and behavior from both cognitive and institutional? Thus, the aim of this study is to propose an analytical base that unifies the cognitive and institutional aspects of the study of individuals and behavior. The specific objectives are developed respectively in three chapters: i) to address the cognitive aspects of individual behavior through the contributions of Simon s bounded rationality, the dual cognitive processes (intuition and deliberation) and heuristics of Kahneman; ii) to present the institutional aspects of the behavior of individuals through Veblenian approach; iii) to indicate the concept of Davis s social identity as a way to unify the cognitive and institutional aspects of the study of individuals and behavior. The proposal to unify the cognitive and institutional dimensions can be represented by the concept of Davis s social identities, since this includes personal and individual identities. Similarly that the social identities maintain the idea of individuals with own personalities, they also consider people as outgoing humans, who have their individual belief inserted in a social environment. That is, through social identities are connected both cognitive and institutional aspects that make up individuals. / O estudo sobre indivíduos e comportamento não é recente na Economia e perpassa diferentes escolas de pensamento. Abordagens que reforçam as críticas às concepções tradicionais neoclássicas de indivíduo isolado e cognitivamente perfeito trazem contribuições de outras ciências, como a Psicologia, a Sociologia e a Filosofia. Ao analisar o comportamento é preciso considerar os elementos que compõem os indivíduos: a cognição - os processos da mente humana - e as instituições - os instintos e os hábitos. Então, como construir uma base analítica que considere indivíduos e comportamento a partir de aspectos tanto cognitivos quanto institucionais? Desta forma, o objetivo geral deste trabalho é propor uma base analítica que unifique os aspectos cognitivos e institucionais do estudo dos indivíduos e comportamento. Os objetivos específicos são desenvolvidos respectivamente em três capítulos: i) abordar os aspectos cognitivos do comportamento dos indivíduos através das contribuições da racionalidade limitada de Simon, dos processos cognitivos duais (intuição e deliberação) e das heurísticas de Kahneman; ii) apresentar os aspectos institucionais do comportamento dos indivíduos através da abordagem vebleniana; iii) indicar o conceito de identidade social de Davis como uma maneira de unificar os aspectos cognitivos e institucionais do estudo sobre indivíduos e comportamento. Assim, a proposta de unificação das dimensões cognitivas e institucionais pode ser representada pelo conceito de identidades sociais de Davis, uma vez que este contempla as identidades pessoais e individuais. Da mesma forma que as identidades sociais mantêm a ideia de indivíduos com personalidades próprias, elas também consideram as pessoas como seres humanos sociáveis, que possuem suas convicções individuais inseridas em um ambiente social. Ou seja, através das identidades sociais são conectados tanto os aspectos cognitivos quanto institucionais que compõem os indivíduos.

O uso de Ambientes Virtuais (AVs) não-imersivos em educação ainda não foi devidamente explorado e estudado, porém alguns autores já demonstram a diferença que a Realidade Virtual (RV) pode fazer no aprendizado. A linguagem Virtual Reality Modeling Language (VRML) é uma proposta para a introdução de AVs não-imersivos na internet; é uma linguagem independente de plataforma, que permite a criação de AVs por onde se pode passear, visualizar objetos por ângulos diferentes e com eles interagir. Assim, os estudantes podem beneficiar-se dessa tecnologia, pois ela lhes permite acessar objetos que descrevem assuntos e contextos do conteúdo abordado e informações verbal-escritas da disciplina, podendo manuseá-los. Este trabalho possui três partes: na primeira, investigam-se as questões que envolvem o uso de AVs no ensino-aprendizagem de matemática para o desenvolvimento dos aspectos cognitivos; as experiências e as condições necessárias para o uso dessa tecnologia na educação de matemática, como a construção do conhecimento e o desenvolvimento de aspectos cognitivos e lógico-matemáticos. Na segunda parte, propõe-se um modelo conceitual de um ambiente de aprendizagem para o ensino-aprendizagem de matemática, sendo, após, realizada a implementação do ambiente de aprendizagem proposto. A terceira parte reporta um estudo de caso, no qual um AV modelado em VRML é aplicado aos alunos de uma escola. Alguns dados dessa aplicação são levantados e analisados estatisticamente com o fim de se avaliar o desempenho do uso do protótipo no ensino-aprendizagem de matemática. / The use of non-immersive virtual environments in education has not been studied, as it should have been. However, some authors have already demonstrated the benefits coming from using such technology. VRML - Virtual Reality Modeling Language provides means for using virtual environments in the Internet. It is a platformindependent language that allows the specification of virtual environments where users can walk in, observe different objects and interact with them. Students can benefit from this technology, since it allows them to access objects describing subjects that students should study. This work is presented in three parts. In the first one, we investigate the use of virtual environments in math education for developing cognitive aspects, the experiences and necessary conditions for using this technology in improving logic and mathematical thinking. In the second part, we present both the conceptual model and the implementation of an educational tool intended to help in math education. The third part is a case study: we have developed a virtual environment using VRML, and it has been applied in math classes for 7th grade students.

O Câncer Colorretal (CCR) consiste no terceiro tipo de câncer mais comum em homens e o segundo em mulheres. O tratamento, na maioria dos casos, implica na cirurgia geradora de estoma, que constitui um procedimento invasivo, com grande impacto em todas as áreas na vida da pessoa. O presente estudo teve por objetivos investigar prospectivamente variáveis relacionadas à imagem corporal, sintomas ansiosos e depressivos, domínios da Qualidade de Vida Relacionada a Saúde (QVRS) e as cognições, emoções e comportamentos diante do processo de adaptação ao estoma. Trata-se de um estudo exploratório, longitudinal e de abordagem quanti qualitativa. A amostra foi composta por pacientes adultos (n=122), de ambos os sexos, atendidos no Ambulatório de Estomaterapia do Hospital de Câncer de Barretos (SP). A avaliação quantitativa foi realizada em todos os pacientes e a qualitativa em 26 dos pacientes, sorteados aleatoriamente. Os participantes foram avaliados em quatro momentos (pré-operatório, três, seis e quinze meses após a cirurgia) e foram subdivididos de acordo com o tipo de procedimento cirúrgico realizado (Anastomose Primária, Estomia Intestinal Temporária e Estomia Intestinal Definitiva). Para a coleta de dados, foram utilizados os instrumentos: questionário de dados sociodemográficos; Critério de Classificação Econômica Brasil; ficha de condições clínicas; Escala de Figura de Silhuetas (EFS); Escala de Ansiedade e Depressão para Hospital Geral (HADS); Questionários para avaliação da QVRS (EORTC QLQ-C30/ QLQ-CR38); Medida subjetiva de pensamentos e emoções e Roteiro de entrevista semiestruturada. Os resultados demonstraram que a amostra foi constituída por pacientes mais velhos, de baixa renda e escolaridade. Os valores médios encontrados na avaliação da imagem corporal indicaram uma superestimação desta. Apesar dos participantes não terem apresentado sintomatologias graves para ansiedade e depressão, de acordo com a escala HADS, as comparações estatísticas infere-se que, quanto pior a sintomatologia para ansiedade e depressão, pior a saúde global. Segundo o EORTC QLQ-C30 e QLQ-CR38 a maioria dos domínios de QVRS apresentaram níveis moderados, sendo que os piores sintomas foram os sexuais. A depressão influenciou de forma direta e negativa na saúde global, assim como na acurácia da imagem corporal. Foram encontradas diferenças significantes entre os grupos na comparação das variáveis nos diversos momentos de avaliação, sugerindo que o nível dos sintomas variou de acordo com o tempo. Não foram encontradas altas frequências para as distorções cognitivas nesses pacientes, entretanto, observou-se pela entrevista semiestruturada que na primeira avaliação existia grande preocupação quanto às limitações ocasionadas pela estomia intestinal em detrimento da percepção de normalidade, frequentemente reportada na última avaliação. Conclui-se que a entrevista qualitativa complementou os resultados encontrados na abordagem quantitativa, sendo que a análise de conteúdo reforçou que os pacientes, em geral, apresentaram boa adaptação à estomia. O suporte social foi apontado como uma das principais estratégias utilizadas no processo de adaptação. Neste sentido, orientações psicoeducativas aos pacientes e familiares devem ser realizadas desde o diagnóstico, a fim de contribuir para adaptação ao estoma. / The Colorectal Cancer (CRC) is the third most common type in men and the second in women. The treatment in most cases implies a surgery with a stoma, which is an invasive procedure, with a great impact in all areas in a person\'s life. This study aimed to prospectively investigate variables related to body image, depression and anxiety symptoms, areas of Health Related Quality of Life (HRQoL) and cognitions, emotions and behaviors related to the adaptation process to the stoma. It is an exploratory study, longitudinal, with quantitative and qualitative approach. The sample consisted of adult patients (n = 122), of both sexes, attended in Stomatherapy Clinic of Barretos Cancer Hospital. The quantitative evaluation was performed in all patients and the qualitative evaluation was performed in 26 patients randomly selected. Participants were assessed at four time points (preoperative, three, six and fifteen months after surgery) and were subdivided according to the type of surgical procedure performed (Primary Anastomosis, Temporary Intestinal Ostomy and Definitive Intestinal Ostomy). For data collection, the follow instruments were used: socio-demographic questionnaire; Brazilian Economic Classification Criteria; clinical conditions record; Figures of Silhouettes Scale (FSS); Hospital Anxiety and Depression Scale (HADS); Questionnaires to assess the HRQoL (EORTC QoL-C30 / QoL-CR38); Subjective measure of thoughts and emotions and Semi-structured interviews. The results showed that the sample was composed of older patients, with low income and low education level. The mean values found in the evaluation of body image showed an overestimation of it. Although the participants did not show servere symptomatology for anxiety and depression, according to the HADS, statistical comparisons inferred that, the worse the symptoms for anxiety and depression, worse overall health. According to the EORTC QoL-C30 and QoL-CR38 most HRQoL domains showed moderate levels in which the worst symptoms were sexual. Depression had a direct and negative impact on global health, as well as the accuracy of body image. Significant differences were found between groups when comparing the variables in the different time points, suggesting that the level of symptoms varied according to the time. There were no high frequencies for cognitive distortions in these patients; however, the semi-structured interview shows that in the first assessment there was great concern about the limitations caused by intestinal ostomy at the expense of perceived \"normal\" often reported in the last assessment. We conclude that the qualitative interview complemented the findings in quantitative approach, and the content analysis emphasized that patients generally showed good adaptation to the stoma. Social support was considered one of the main strategies used in the adjustment process. In this sense, psychoeducational guidance to patients and their families must be carried out from diagnosis, in order to contribute to the adaptation to the stoma.

The availability and scale of user generated data in online systems raises tremendous challenges and opportunities to analytic study of human activities. Effective modeling of online human activities is not only fundamental to the understanding of human behavior, but also important to the online industry. This thesis focuses on developing models and algorithms to predict human activities in online systems and to improve the algorithmic design of personalized/socialized systems (e.g., recommendation, advertising, Web search systems). We are particularly interested in three types of online user activities, i.e., decision making, social interactions and user-generated contents. Centered around these activities, the thesis focuses on three challenging topics: 1. Behavior prediction, i.e., predicting users' online decisions. We present Collaborative-Competitive Filtering, a novel game-theoretic framework for predicting users' online decision making behavior and leverage the knowledge to optimize the design of online systems (e.g., recommendation systems) in respect of certain strategic goals (e.g., sales revenue, consumption diversity). 2. Social contagion, i.e., modeling the interplay between social interactions and individual behavior of decision making. We establish the joint Friendship-Interest Propagation model and the Behavior-Relation Interplay model, a series of statistical approaches to characterize the behavior of individual user's decision making, the interactions among socially connected users, and the interplay between these two activities. These techniques are demonstrated by applications to social behavior targeting. 3. Content mining, i.e., understanding user generated contents. We propose the Topic-Adapted Latent Dirichlet Allocation model, a probabilistic model for identifying a user's hidden cognitive aspects (e.g., knowledgability) from the texts created by the user. The model is successfully applied to address the challenge of ``language gap" in medical information retrieval.

Critical and enduring questions for teachers are whose ethics or what ethics they should be teaching in schools and how, given the pluralism of the wider society. The focus of this study is to establish whether it is possible to identify a common, non-relativist basis for what should be taught in Ethics Education and then to consider how such an approach might best be undertaken. This task involves finding some basis for ethics that we all have reason to accept and requires an understanding of the nature of moral development and learning. An interdisciplinary approach has been undertaken to investigate whether it is possible to find a common basis for ethics and to determine what constitutes the nature of moral development and learning. In the first instance, this interdisciplinary approach has been used to investigate whether there is justification for believing that as human beings we share certain characteristics and patterns of behaviour, or a common humanity, the features of which might suggest a common basis for ethics that we all have reason to accept. This investigation examines empirical findings and theoretical conclusions relating to the sociobiological, psychosocial and sociocultural dimensions of human beings to support the notion that we share a common humanity which is characterised by a number of features. These features include the deeply reciprocal nature of our relationships with one another and the sociocultural nature of our moral learnings. Moreover, we are a highly interdependent social species whose survival and well-being are dependent not only on cooperation with one another but also with sustaining a satisfactory ecological balance with other forms of life within dynamic, natural systems. This interdependence suggests that the norm of having care for one another and our world is one that we all have reason to accept. This norm, in turn, suggests a telos, or set of goals for ethics, that involve the creation of a just and caring society. However, in order to realise such a telos for ethics it is necessary to provide some specific theoretical and practical guidelines related to deciding what constitutes the nature and scope of care within specific contexts. Accordingly, the study undertakes a brief review of contemporary approaches to ethics to evaluate the extent to which these provide a means for realising the ethical form of life based in the norm of having care for one another and our world. This review suggests that feminist theories of care provide the most promising basis for delineating what it is to care for one another and our world. However, it is also acknowledged that there are a number of limitations with existing theories of care. This study, therefore, undertakes a conceptual analysis of the nature and scope of care and outlines an extended ethic of care. This theorising recognises that care for others is characterised by the dimensions of responsiveness, the exercise of responsible action and is refined and amended by critical reflection. It is acknowledged that justice is intrinsic to the nature of care as is the exercise of a range of virtues. The scope of our caring responsibilities is seen to extend to all others in the global community, as well as all other species, while also requiring care for self, and care for particular others for whom we may have special familial or work-related responsibilities. The evaluation of what constitutes caring practice is also discussed and it is acknowledged that caring practices must meet minimum requirements in terms of respect for basic human rights and should contribute to the welfare and well-being of the recipients of care. This specification of the nature and scope of care, in conjunction with a consideration of the nature of moral learning and development, provides a basis from which to develop a philosophical foundation as well as a set of aims and objectives for Ethics Education. It is acknowledged that students need to develop a wide range of cognitive, emotional and social competencies in order to understand what it means to care for self and others within specific socio-cultural contexts and also to develop the sense of empathetic connection and affiliation to others that translates moral decisions into responsible moral action. It is hoped that the study provides the basis for beginning a dialogue in schools that involves students, teachers, families and members of the wider community about what it means to live the ethical form of life and how education itself might promote broadly such a form of life.

The present thesis explores how answering questions on values in surveys could be influenced. Findings about cognitive processes occurring in general during answering questions, as well as factors that may influence the given answers are presented in the first part of the theoretical section. Afterwards, Schwartz's circular model of values is presented together with the instruments he developed to measure their importance. At the end of the theoretical section, the results of existing studies on the possibilities of influencing values are described. A series of three experimental online studies, involving nearly 600 respondents, builds on the findings presented in the theoretical section. The experiments examine the malleability of individualistic and collectivistic values based on induced changes in regulatory focus and self-construal of participants. In the first of the studies, the given values were affected by the content of previous questions, but this effect was in the opposite direction than originally anticipated. In the next two studies, the experimental manipulation did not lead to significant differences between groups. Causes of the results, limits of the conducted studies and prospects for future research are discussed in the last sections of the thesis.

Research demonstrating the beneficial effects of corrective feedback (CF) for second language (L2) learning (e,g., Li, 2010) has almost invariably resulted from studies in which CF was provided immediately. Yet teachers are often encouraged to delay CF to avoid interrupting learners (Harmer, 2001). This study investigates how differences in the timing of CF on oral production affect L2 learning and learners’ reactions to CF. Theoretically, Immediate CF may facilitate L2 development by allowing learners to immediately compare their errors to accurate models (i.e., recasting, e.g., Doughty, 2001). The effectiveness of Immediate CF has also been linked to skill acquisition theory because some CF (i.e., prompting) is hypothesized to help learners proceduralize their L2 knowledge (Ranta & Lyster, 2007). This thesis introduces additional theoretical explanations to explain the effectiveness of both Immediate and Delayed CF. For example, reactivation and reconsolidation theory (Nader & Einarsson, 2010) holds that long-term mental representations are susceptible to change when they are recalled. Thus, both Immediate and Delayed CF may help learners alter their incorrect mental representations of language features if that CF reminds learners of those incorrect representations and provides them with accurate models. In a laboratory-based study, 90 intermediate-level adult ESL learners were randomly assigned to Immediate, Delayed, and No CF conditions. Learners took three pre-tests to measure their knowledge of the English passive construction: an aural grammaticality judgment test (AGJT), an oral production test (OPT), and a written error correction test (ECT). Next, they received some brief instruction on the passive. Learners then completed three communicative tasks in which the CF conditions were provided. These tasks were followed by immediate and delayed post-tests. Learners’ reactions to CF were elicited with a questionnaire. Mixed-design one-way ANOVAs revealed statistically significant improvement for all conditions over time on all measures, but no statistically significant differences between conditions. The questionnaires revealed that learners prefer Immediate CF, but that Immediate CF may constrain CF noticeability and learners’ independence, while Delayed CF may cause anxiety or embarrassment. In summary, altering the timing of CF did not differentially affect L2 development, but it did elicit different reactions from learners.
