O objetivo deste estudo foi analisar os condicionantes das decisões de investimento das empresas familiares. Para tanto, utilizou-se de um referencial teórico baseado em conceitos como estrutura de propriedade e controle familiar, heterogeneidade das empresas familiares, choques exógenos causados por crises econômicas e situação de restrição financeira. Esses conceitos foram empregues com o propósito de dimensionar seus impactos nas decisões de investimento das empresas familiares listadas em bolsa nos períodos entre 2006-2016. Em termos teóricos, os investimentos foram separados em dois tipos: investimentos em CAPEX e capital circulante líquido. Embora nem todos tenham sido utilizados em todas as fases da pesquisa, esses dois tipos de investimento foram o cerne e a variável dependente da pesquisa. Outras variáveis importantes foram Empresa Familiar, bem como suas outras sete configurações, e as variáveis de interação como idade, grau de maturidade, tamanho, tangibilidade e situação financeira. Outro ponto considerado pela pesquisa foi o impacto do cenário macroeconômico sobre as decisões de investimento. Os resultados encontrados mostraram que as empresas familiares investem menos do que as empresas não familiares em CAPEX, ocorrendo o inverso para o capital circulante líquido. Isso corrobora com as análises teóricas promovidas por Anderson, Duru e Reeb (2012) e Chrisman e Patel (2012) sobre os ideais de autopreservação e aversão ao risco aos quais as empresas familiares estão sujeitas. Quanto aos períodos de choques de liquidez, as empresas familiares apresentaram quedas severas para investimentos em CAPEX e quedas menos acentuadas para o capital circulante líquido. Por fim, em relação à situação de restrição financeira e os resultados financeiros passados evidenciou-se que empresas familiares com maior tangibilidade e com resultados passados positivos investem mais do que as empresas não familiares, o que também está de acordo com a teoria sobre autoconfiança e busca pela perenidade em empresas de controle familiar. / The objective of this study was to answer the following research problem: what are the determinants of the investment decisions of family companies? To do so, the research used a theoretical framework based on concepts such as family ownership and control, the heterogeneity found in the various types of family businesses, exogenous shocks caused by economic crises and the situation of financial constraint of the companies. These concepts were used to understand how each of them impacted the investment decisions of listed companies in the period between 2006-2016. In conceptual terms, the investments were divided into two types: investments in CAPEX and working capital ratios. Although not all were used at all stages of the research, these three types of investment were at the heart and the research-dependent variable. In addition to this variable, other important variables were both the Family Enterprise variable (as well as its other seven configurations) and the variables of interaction with age, maturity level, size, tangibility and financial situation. Another point considered by the research consisted in analyzing how the macroeconomic scenario impacted investment decisions. The results found that family firms invest less than non-family firms (in all configurations) in CAPEX. However, the opposite occurs for the working capital ratios. This corroborates theoretical analyzes promoted by Anderson, Duru and Reeb (2012) and Chrisman and Patel (2012) on the ideals of self-preservation and risk aversion to which family firms are subject to making decisions involving risks and uncertainties. Comparing the results in periods of liquidity shocks, the results of the family companies showed severe declines for investments in CAPEX and less declines in working capital index. Finally, the results found when considering the situation of financial constraint and the past results provided that family companies with greater tangibility and with positive past results invest more than non-family companies, which is also in accordance with the theory on self-preservation and search for perpetuity in family businesses.

Este trabalho versa sobre o conceito de potência natural em Espinosa, sua amplitude e abrangência e seus reflexos no direito natural e na política. Procura revelar a originalidade do conceito de direito natural em Espinosa, muito diferente dos pontos de vista de Grotius, de Hobbes e de todos os demais filósofos e doutrinadores, levando-o, também, a uma visão diferente sobre a formação do Estado; e, finalmente, a sua doutrina sobre o Estado e suas diversas instituições políticas, enfatizando sempre a liberdade e a dignidade humanas como a razão de ser da criação desse mesmo Estado. Procuramos também revelar neste modesto trabalho o avanço, a novidade e a contribuição de Espinosa à ciência jurídica contemporânea. / This paper deals with the concept of natural power in Spinoza, its breadth and scope and its effects on natural law and politics. Seeks to reveal the originality of the concept of natural law in Spinoza, very different from the views of Grotius, Hobbes and all other philosophers and scholars, too, leading him to a different view of state formation; and finally, his teaching on the State and its various political institutions, always emphasizing freedom and human dignity as the reason for the creation of that State. We also seek to reveal in this modest work the advance, the novelty and contribution of Spinoza to contemporary legal science.

Orientador: Alfredo Pereira Junior / Banca: Adrian Oscar Montoya / Banca: João de Fernandes Teixeira / Resumo: Neste trabalho nos propomos a analisar a consciência a partir da perspectiva neurobiológica de Antonio Damásio. Para isso, sugerimos um percurso investigativo que se inicia com uma abordagem histórico-filosófica. Destacamos neste contexto, a noção cartesiana do dualismo substancial, caracterizada por se conceber mente e corpo como realmente distintos. Contrariamente a essa concepção, apresentamos o monismo naturalista de Espinosa, que procurou compreender a mente e o corpo como partes integrantes da natureza. Em seguida, procuramos apresentar uma possível aproximação entre o monismo naturalista de Espinosa e a abordagem neurobiológica de Damásio. Para Damásio (1996, 2000, 2004), a consciência emerge em uma rede neural integrada, a partir das interações entre cérebro, corpo e ambiente. Apesar de possuir suas bases biológicas, a consciência não se reduz a elas. Formas inovadoras e complexas vão surgindo, na medida em que os processos de interação com o ambiente se ampliam. Procuramos mostrar que a consciência, seja ela elementar (proto-self) ou complexa (consciência ampliada) tem por finalidade contribuir para a manutenção e preservação da vida. / Abstract: In this work I analyze consciousness from the neurobiological perspective of Antonio Damásio. The investigation begins with a historical review of philosophical approaches to the mind-body problem. I focus on the Cartesian notion of substantial dualism, characterized for conceiving mind and body as really different and separated entities. Contrary to this conception, the naturalistic monism of Espinosa understands mind and body as parts of nature. After this review, I look for a possible approximation between the naturalistic monism of Espinosa and the neurobiological approach of Damásio. For Damásio (1996, 2000, 2004), consciousness emerges, in an integrated neural net, from the interaction of brain, body and environment. Although possessing a biological basis, consciousness cannot be reduced to biology. Innovative and complex forms appear in the processes of interaction of the brain with the body and environment. In my discussion of Damásio I suggest that consciousness, either elementary (proto-self) or complex (extended conscience), has the purpose of contributing to the maintenance and preservation of life. / Mestre

Ce travail de thèse porte sur la question de l’existence de représentations, sous forme picturale (dessins, peintures…), exécutées par certains sujets pendant leur internement dans les camps de concentration nazis, dans un contexte de traumatisme extrême, considéré comme de l’ordre de l’irreprésentable. A partir d’une étude de cas de trois sujets dessinateurs/trices, et de leur production picturale, abordée selon la méthode de la psychanalyse appliquée au sens d’André Green, une réflexion peut s’amorcer autour de l’hypothèse d’une autoconservation, différenciée, physique et psychique. Afin de la mener à bien sont résumées les représentations historiques après-coup, puis cernées la problématique du traumatisme extrême dans les camps de concentration et la création d’un point de vue psychanalytique avec des auteurs tels que Freud, Férenczi, Winnicott, Roussillon, Green, Bertrand, Zaltzman, Cerf de Duzeele, Waintrater et Cupa. Les résultats amènent à constater l’existence chez ces sujets d’une aire intermédiaire qui leur a permis de conserver une activité représentationnelle particulière. Celle-ci constitue un travail de représentation de la surréalité déréalisante du camp, principalement utilisé dans une autoconservation psychique. Inscrit dans un fil de culture, de filiation et d’historicisation, il participe d’un travail de liaison intrapsychique et intersubjectif ainsi que d’une lutte contre la désintrication pulsionnelle. Des fantasmes omnipotents d’éternité sous-jacents aux dessins vont de pair avec, dans l’activité, une coexcitation libidinale qui ouvre sur la question d’une éventuelle sublimation / This thesis begins with noticing that pictorial representations (e.g. drawings or paintings etc.) in nazi concentration camps have been made by some subjets while imprisonment, in a massive traumatism, usually thinked as a non-representable situation. From a three drawers and drawings study, imcompletely by Andre Green’s applied psychoanalysis method, reflexion can occur with the hypothesis of a dissociated physical and psychic self-preservation in that context. To achieve this goal, historical nazi camps differed representations, massive traumatism and creation, are detailed in a psychoanalytic viewpoint with Freud, Ferenczi, Winnicott, Roussillon, Green, Bertrand, Zaltzman, Cerf de Duzeele, Waintrater and Cupa as main authors. Results show the existence of an intermediate space that enabled these subjets to keep a specific representational activity. It’s mainly a representation work of the camp overreality in a psychic self-preservation way. This work is an internal and external connection work, in a culture and filiation link, that struggles against drive defusion. Eternity and omnipotent fantasy, libidinal coexcitation underly drawings and pictorial activity. They interrogate about a possible sublimation

Over the course of four sections this PhD examines the ways in which the Aristotelian, Stoic and Epicurean philosophers portray bodily activity. In particular, it argues that their claims regarding bodies' natural tendency to preserve themselves, and seek out the goods capable of promoting their well-being, came to influence Hobbes's and Spinoza's later accounts of natural, animal and social behaviour. The first section presents the ancient accounts of natural and animal bodily tendencies and explores the specific ways in which the Aristotelian, Stoic and Epicurean views on animal desires came to complement and diverge from each other. After investigating the perceived links between natural philosophy, psychology and ethics, the section proceeds to consider how the ancients used this 'unified' view of nature to guide their accounts of the soul's primary appetites and desires. Also examined is the extent to which civil society is portrayed as a means of securing the individual against others, and how Aristotelian philia, Theophrastian oikeiotês and Stoic oikeiōsis came to stand in opposition to the fear-driven and compact-based accounts of social formation favoured by the Epicureans. The second section considers how the ancient accounts of impulsive behaviour and social formation were received and diffused via new editions of ancient texts, eclectic readings of Aristotle, and the attempts of Neostoic and Neoepicurean authors to update and systematise those philosophies from the late sixteenth century onwards. The particular treatments of Hellenistic thought by authors such as Justus Lipsius, Hugo Grotius and Pierre Gassendi are considered in detail and are placed within the context of the growing trend to use Stoic and Epicurean thought to replace the authority of Aristotle in the areas of science, psychology, and politics. The final two sections are devoted respectively to considering the ways in which Hobbes and Spinoza encountered the Hellenistic accounts of bodies and demonstrating how these earlier accounts came to feature in each of their own discussions of bodily tendencies. Engaging with a wide range of their texts, each section develops the many nuances and contours that emerged as both writers developed and fine-tuned their accounts of bodily actions. This reveals the many ways in which the ancient accounts of self-preservation helped to unify large aspects of Hobbes's and Spinoza's own philosophical corpus, while equally showing how a well-developed account of bodily tendencies might challenge the scholastic worldview and expand further the boundaries of the so-called 'New Science'.

Turbulent wakes generated from an aircraft or submarine vehicles has been of main interest to researchers due to the broad band noise associated with such wakes. One such case is the noise generated by spiral vortices shed of from one blade interacting with another oncoming blade of helicopter rotor. Consequently, researchers have been trying to understand the basic physics and evolution of such wakes. Although there has been numerous studies done on plane wakes, there has been little research being done on laterally curved wakes. Single and two-point velocity measurements were taken on a plane and laterally curved turbulent wakes to understand the evolution and effect of lateral curvature into the far wake region. The analyses provide useful information in modeling curved or spiral wakes such as turbulence field surrounding tip vortices shed from a wing. In order to achieve our objectives, the Virginia Tech 3’ x 2’ subsonic wind tunnel was used to take velocity measurements of toroidal ring model and a straight cylinder as a control case. Velocity measurements were done using four sensor hot-wire anemometers, to obtain all mean velocity, Reynolds stress, triple product components of the turbulence field. Single point, spectra and two-point measurements of the wakes were performed throughout the development into the far wake region. The single point results reveal the universality of the mean axial velocity, however the Reynolds stresses and triple products were not universal illustrating that the turbulence field has its own length and velocity scales different from that of the mean flow. The effect of lateral curvature is mainly evidenced in the early development of the curved ring wake. The turbulent energy budget reveals similar trend for both wakes and plane wake achieves approximate equilibrium. The spectra result reveals for the plane wake that self-preservation is achieved for all scales of motion, while the ring wake does not achieve such a state. While the longitudinal correlations of both wakes are similar in form, in general difference in form and orientation prevailed over all indicating the difference in the turbulent structure of both wakes. Linear stochastic estimation reveals the presence of spanwise and double-roller eddy structures in the plane wake and only spanwise eddies were detected for the ring wake. / Master of Science

The objective of this study is to examine the emotional regulation strategies used by Walt Disney World on-stage employees as a way to fulfill requirements set forth by the company. Ten Disney on-stage employees were interviewed off-property in Orlando. The emotional regulation framework was divided into several categories: (1) a distinction between deep acting and surface acting, (2) emotional deviance, and (3) emotional exhaustion. “Surface acting” is a strategy by which employees display company-imposed emotions not genuinely felt, whereas “deep acting” occurs when employees do feel the emotions that they are required to express (Hochschild, 1983). Throughout the data reduction process, five key themes surfaced as the most relevant to the initial research questions: (1) Self-Motivated Deep Acting, (2) Organizational Expectations for Surface Acting, (3) “Back-Stage” vs. “Front-Stage” Dichotomy, (4) Benefits of Emotional Training, and (5) Negative Effects of Emotional Regulation. Overall, the researcher found that a key strategy of emotional regulation that Disney employees use frequently is surface acting, although deep acting was found to be more successful. In addition, while emotional exhaustion was a common problem among employees, very few of them will actually engage in emotional deviance in order to avoid the negative consequences of surface acting. Lastly, it was found that highly skilled Walt Disney World employees will have already internalized emotional regulation training and display rules that manage emotional behavior. Therefore, it becomes less essential for the Disney Company to formally monitor its employees’ facial expressions and emotional behavior in the future

Research Doctorate - Doctor of Philosophy (PhD) / In Chapter 1, I describe social competence, task competence and self-protection in an organisational context. In Chapter 2, I review key self theories and relate them to the self-competence construct. In Chapter 3, I review the research on self-competence to show that there is a need for a construct of social competence and self-protection. I discuss the limitations of three self-competence theories: Bandura’s (1977) self-efficacy theory, Williams and Lillibridge’s (1992) self-competence theory and Tafarodi & Swann’s (1995) self-competence/self-liking theory. In Chapter 4, I present my selfcompetence model. I raise the research questions and specify my hypotheses. In Chapter 5, I describe the construction of Social and Task Competence Scale. I present evidence of the reliability and factor structure of the Social and Task Competence Scale. I concluded that scale revisions were needed. In Chapter 6, I present evidence of the reliability, factor structure and predictive validity of the revised Social and Task Competence Scale and Self-Protection Scale. I describe the results of an experiment that investigated the interaction of task setting, social competence, task competence and selfprotection. I concluded that the measures predicted performance. In Chapter 7, I investigate the factor structure and reliability of the revised Social and Task Competence Scale and revised Self-Protection Scale. I provide evidence of the convergent and discriminant validity of these measures with reliable measures of self-competence, selfesteem, self-monitoring, personality and social desirability. In Chapter 8, I investigate the factor structure and reliability of the Social and Task Competence Scale and Self-Protection Scale after final revisions and show that these measures are acceptable for use in scientific research. I present evidence of their convergent validity with a valid andreliable measure of emotional intelligence, and describe experimental results that supported the hypothesised relationships between perceived task difficulty, social competence, task competence and self-protection and task performance. In Chapter 9, I discuss the implications of my research for self-competence theory, self-regulation and self-esteem and the prediction of social and task performance in organisations.
