No. of bitstreams: 1 Gustavo Henrique de Souza_.pdf: 1079480 bytes, checksum: 8fd3bb0bd31939c3ff6017311f7f7863 (MD5) Previous issue date: 2017-07-18 / Nenhuma / O assunto carreira passou por significativas evoluções nas últimas décadas, trazendo uma nova perspectiva da proeminência do indivíduo sobre a organização. A carreira passa a ser compreendida como uma sequência constituída por todas as experiências profissionais do indivíduo ao longo de sua vida. Esta dissertação propõe um modelo ontológico e um sistema de tutoria para gestão de carreiras voltado à aprendizagem de estratégias meta-cognitivas de gestão da carreira. O modelo formaliza as variáveis causais descritas por King para a gestão pessoal de carreiras e está orientado para a carreira de Tecnologia de Informação (TI). Para tanto foi necessário uma análise empírica do mercado de trabalho em TI a fim de elicitar o plano de carreiras desta área, posteriormente formalizada por uma ontologia especificada em OWL. A abordagem pedagógica do sistema de orientação de carreiras MaxMentor, construído para demonstrar à aplicabilidade do modelo, utiliza o conceito de situação problema discutido por Perrenoud (2000). Após apresentar as principais características tecnológicas e arquiteturais do sistema MaxMentor, a dissertação se encerra com a apresentação dos resultados preliminares da avaliação empírica e da usabilidade do sistema, que mostram boas evidências da utilidade do sistema para auxiliar na vida profissional e no pensamento crítico sobre como gerir a própria. / The subject career has undergone significant evolutions in the last decades, bringing a new perspective of the prominence of the individual on the organization. The career begins to be understood as a sequence consisting of all the professional experiences of the individual throughout his life. This dissertation proposes an ontological model and a mentoring system for career management aimed at learning meta-cognitive strategies of career management. The model formalizes the causal variables described by King for personal career management and is career oriented in Information Technology (IT). For this, an empirical analysis of the labor market in IT was necessary to elicit the career plan of this area, later formalized by an ontology specified in OWL. The pedagogical approach of the MaxMentor career guidance system, built to demonstrate the applicability of the model, uses the problem situation concept discussed by Perrenoud (2000). After presenting the main technological and architectural characteristics of the MaxMentor system, the dissertation concludes with the presentation of the preliminary results of the empirical evaluation and the usability of the system, which show good evidence of the usefulness of the system to assist professional life and critical thinking about how to manage their own.

Aspects of the interplay of cognition and emotion and the use of verbal vs. numerical information decision making

Trujillo Valencia, Carlos Andrés 27 June 2007 (has links)
En ésta tesis se estudian 2 aspectos de la toma decisiones. Primero, se investiga la forma en que las personas categorizan atributos numéricos. Se presenta y se prueba experimentalmente un modelo del proceso mental que usan las personas para trasformar una cantidad en una categoría verbal. Bajo ciertas condiciones situacionales, el modelo es capaz de predecir conceptualizaciones verbales. Segundo, se exploran las interconexiones entre la información cognitiva y emocional durante la decisión. Se elaboran y se prueban experimentalmente cuatro modelos de la forma en que se combina la información cognitiva y emocional durante el proceso de elección, para determinar el valor de una alternativa. Los modelos muestran una alta capacidad de predicción. Esta varía en función de (1) la interacción de la información verbal y numérica con la capacidad cognitiva situacional del individuo y (2) la correlación entre los juicios cognitivos y las reacciones emocionales. / The present dissertation investigates two aspects of decision making: First, I study the way in which people understand and categorize numerical attributes of products. I develop and experimentally test a model of the mental process people use to transform a quantitative attribute into a verbal category. Under certain environmental conditions, the model is able to predict the verbal conceptualization of people. Second, I explore the interconnections of cognitive and emotional information during the process of decision making. I propose and experimentally test four different models of the way cognitive and affective information is combined during the decision making process in order to determine the value of an alternative. The models display a high predictive power. Their performance is influenced by (1) the interaction of verbal and numerical information with the situational cognitive capacities of the individual and (2) by the correlation of cognitive judgments and affective reactions.
