Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This study aimed to analyze the relationship between the ties of workers with the organization and the leadership styles of managers in Public and Private Hospitals Nursing team in Rio Grande do Sul (RS). Therefore, we carried out a case study, descriptive and quantitative approach nature. The research sample consisted of 347 nurses, technicians and nursing assistants from a public and a private hospitals, located in the city of Porto Alegre/RS. To collect data, we used a research protocol (questionnaire) with closed items, divided into three parts: personal and occupational data; Ties to the Organization; and Leadership styles. Data analysis was performed using the software "Microsoft Excel" version 2010, SPSS version 18 and SAS version 9.1, by calculating descriptive statistics, groups comparison of techniques and correlation analysis - Pearson correlation coefficient. The data obtained in the analysis revealed that the correlations between the constructs all associations were positive, which indicates there is some form of direct relation between them. Considering the relationship between "Ties with the Organization" and "Leadership Styles" concluded for the study context, the Organizational Commitment correlated more strongly with the Transformational Leadership and its Intellectual Stimulation basis, as Organizational Consent also bound more strongly with this leadership and its base Charisma or Idealized Influence. At the same time, the Organizational Entrenchment was related significantly only with Leadership Absence, showing that, on this link, very little is perceived by employees as of leadership responsibility. From these results, we can say that the ties that workers develop with their organizations are related to leadership styles of their managers, or the absence of these, some with a stronger intensity, other weaker, but all positively associated. / Este estudo teve como objetivo analisar a relação entre os vínculos dos trabalhadores com a organização e os estilos de liderança dos gestores na equipe de Enfermagem de Hospitais Públicos e Privados no Rio Grande do Sul (RS). Para tanto, realizou-se um estudo de caso, de natureza descritiva e abordagem quantitativa. A amostra da pesquisa foi composta por 347 enfermeiros, técnicos e auxiliares de enfermagem de um Hospital público e um Hospital privado, localizados na cidade de Porto Alegre/RS. Para a coleta de dados utilizou-se um protocolo de pesquisa (questionário) composto por itens fechados, divididos em três partes: Dados pessoais e ocupacionais; Vínculos com a Organização; e, Estilos de Liderança. A análise dos dados foi realizada com o auxílio dos softwares Microsoft Excel versão 2010, SPSS versão 18 e SAS versão 9.1, por meio de cálculo de estatísticas descritivas, técnicas de comparação de grupos e análise de correlação - coeficiente de correlação de Pearson. Os dados obtidos nessa análise revelaram que, entre as correlações dos construtos, todas as associações foram positivas, o que indica haver alguma forma de relação direta entre estes. Considerando a relação entre Vínculos com a Organização e Estilos de Liderança concluiu-se, para o contexto de estudo, que o Comprometimento Organizacional se correlacionou mais intensamente com a Liderança Transformacional e sua base Estimulação Intelectual, à medida que o Consentimento Organizacional também se ligou mais fortemente com essa liderança e sua base Carisma ou Influência Idealizada. Ao mesmo tempo, o Entrincheiramento Organizacional relacionou-se significativamente apenas com a Ausência de Liderança, demostrando que, em relação a este vínculo, muito pouco é percebido pelos colaboradores como de responsabilidade da liderança. Diante desses resultados, é possível afirmar que os vínculos que os trabalhadores desenvolvem com suas organizações estão relacionados aos estilos de liderança dos seus gestores, ou a ausência destes, sendo algumas com uma intensidade mais forte, outras mais fracas, mas todos positivamente associados.

In this thesis, a particular class of agent is singled out for examination. In order to provide a guiding metaphor, we speak of control room agents. Our focus is on rational decision- making by such agents, where the circumstances obtaining are such that rationality is bounded. Control room agents, whether human or non-human, need to reason and act in a changing environment with only limited information available to them. Determining the current state of the environment is a central concern for control room agents if they are to reason and act sensibly. A control room agent cannot plan its actions without having an internal representation (epistemic state) of its environment, and cannot make rational decisions unless this representation, to some level of accuracy, reflects the state of its environment. The focus of this thesis is on three aspects regarding the epistemic functioning of a control room agent: 1. How should the epistemic state of a control room agent be represented in order to facilitate logical analysis? 2. How should a control room agent change its epistemic state upon receiving new information? 3. How should a control room agent combine available information from different sources? In describing the class of control room agents as first-order intentional systems hav- ing both informational and motivational attitudes, an agent-oriented view is adopted. The central construct used in the information-theoretic approach, which is qualitative in nature, is the concept of a templated ordering. Representing the epistemic state of a control room agent by a (special form of) tem- plated ordering signals a departure from the many approaches in which only the beliefs of an agent are represented. Templated orderings allow for the representation of both knowledge and belief. A control room agent changes its epistemic state according to a proposed epistemic change algorithm, which allows the agent to select between two well-established forms of belief change operations, namely, belief revision and belief update. The combination of (possibly conflicting) information from different sources has re- ceived a lot of attention in recent years. Using templated orderings for the semantic representation of information, a new family of purely qualitative merging operations is developed. / School of Computing / Ph. D. (Computer Science)
