This thesis analyses the method, purpose, and results of Aristotle's treatment of a select number of Presocratic and Platonic theses about the soul within the context of De Anima 1. Contrary to a prevalent interpretation of De Anima 1 which sees Aristotle's treatment of his predecessors' psychological views as dialectical, I argue that Aristotle treats his predecessors as having offered potentially viable hypotheses about the nature of the soul, and that these hypotheses are treated as attempts to explain the soul's basic powers. I further show that, in order to test the explanatory limits of these theories, Aristotle uses a version of the scientific method of inquiry advertised in the Prior and Posterior Analytics, which consists in setting out the basic psychological phenomena which psychology should explain, and then testing the extent to which his predecessors' definitions of the soul are able to accomplish this task. This thesis argues that, by demonstrating where his predecessors' first principles fall short, Aristotle is able to make theoretical progress towards establishing his own 'hylomorphic' first principle of soul, that soul is the 'first fulfilment of a natural instrumental body', and towards the idea that soul operates in the body of living beings as a formal, final, and efficient cause.

A partir do início da década de 90, com a desregulamentação do setor, os produtores de cana-de-açúcar do Brasil passaram a ser livres para se juntarem voluntariamente à associação do seu agrado. O caráter voluntário passou a posicionar o associado como cliente da associação e, portanto, atrair e manter membros tornou-se essencial para a perpetuação das associações, bem como compreender o que os conduz à satisfação. Nesse contexto, o presente estudo teve como objetivo identificar os elementos que determinam a satisfação apresentada pelos produtores de cana-de-açúcar com as associações da qual fazem parte. Baseado na literatura foi desenvolvido um modelo composto por seis variáveis independentes aglomeradas em dois tipos: benefícios individuais (vantagem econômica, contatos, serviços seletivos) e benefícios coletivos (serviços coletivos, representação, lobby). O modelo também foi composto por quatro variáveis moderadoras: tamanho da associação, heterogeneidade da associação, comunicação face-a-face com a associação e informações sobre ações passadas. Para o alcance do objetivo e teste do modelo, foi realizada uma pesquisa de caráter quantitativo e explicativo, por meio de 230 questionários válidos aplicados diretamente aos produtores durante eventos. Para a verificação do modelo elaborado, foram realizadas análises descritivas, testes de correlação, de regressão linear múltipla e de moderação. Os resultados identificaram que todas as seis variáveis independentes apresentam correlação positiva com a satisfação, indicando haver uma relação positiva entre elas e a satisfação. Entretanto, apenas três delas apresentaram um efeito significativo na regressão linear múltipla: vantagem econômica (?=0,461), representação (?=0,437) e serviços seletivos (?=0,115). Os resultados também mostraram que os aspectos individuais influenciam mais a satisfação dos produtores do que os aspectos coletivos. Por fim, os resultados indicaram que a heterogeneidade da associação e a comunicação face-a-face apresentaram um efeito moderador sobre a relação entre vantagem econômica e satisfação e a heterogeneidade e informações sobre ações passadas apresentaram um efeito moderador sobre a relação entre representação e satisfação. / From the beginning of the 90s, with the deregulation of the sector, producers of sugarcane in Brazil became free to voluntarily join the association of their liking. The voluntary character passed the position members as customers and therefore attract and retain members and understanding what leads to satisfaction has become essential to the perpetuation of the associations. In this context, the study aimed to identify the elements that determine the satisfaction displayed by sugar cane producers, the Center-South region of Brazil, with the associations they belong to. Based on the literature, it was developed a model composed of six independent variables clustered into two types: individual benefits (economic advantage, contacts, selective services) and collective benefits (collective services, representation, lobbying). The model was also composed by four moderating variables: size of the association, heterogeneity of the association, face-to-face communication and information about past actions. For the data analysis and model test, a quantitative and explanatory research was performed, through 230 valid questionnaires, applied directly to producers during events. Descriptive analysis, correlation test, multiple linear regression and moderation test were used. The results showed that all independent variables are positively correlated with satisfaction, indicating a positive relationship between them and the satisfaction. However, only three of them have had a significant effect on multiple linear regression: economic advantage (? = 0.461), representation (? = 0.437) and selective services (? = 0.115). The results also showed that individual aspects influence satisfaction more than the collective aspects. Finally, the results indicated that the heterogeneity of the association and face-to-face communication had a moderating effect on the relationship between economic benefit and satisfaction and heterogeneity and information about past actions had a moderating effect on the relationship between representation and satisfaction.

Using common subexpressions to speed up a set of queries is a well known and long studied problem. However, due to the isolation requirement, operating a database in the classic transactional way does not offer many applications to exploit the benefits of simultaneously computing a set of queries. In the opposite, many applications can be identified in the context of data warehousing, e. g. optimizing the incremental maintenance process of multiple dependent materialized views or the generation of application specific data marts. In the paper we discuss the problem whether it is always advisable to generate the most complete common predecessor for a given set of queries or to restrict a predecessor to a subset of all possible base tables. As we will see, this question cannot be answered without having knowledge about the cardinality of queries after aggregation. However, if we can rely on this information, we can come up with an optimal predecessor for a common set of queries.

The introductory chapters describe the reasons for the economic, social and political crisis, resulting in the unrest in Europe in the early 15th century and is shown activity Hus's predecessors Konrad Walhauser, John Milíč of Kromeriz, Matthew of Janov, Vojtech Raňkův from Ježov, Thomas Štítný of Štítné. The diploma thesis is also engaged in the work of John Wycliffe, who influenced the thinking of scholars throughout Europe, including Bohemia, where from his thoughts and opinions drew Jan Hus. The core diploma thesis is to analyze the life and the work of Jan Hus, its importance for the development of Czech history. Hus, influenced by his predecessors, became a leading critic of the Church and its influence goes beyond the 15th century. The diploma thesis shows the influence Hus's thoughts and actions in education and elementary education in the 15th and 16 century. Hus influenced the development of the Czech language and spelling. The ideas of Jan Hus had affected the brotherly unity, that followed the Hussite movement intellectually and spiritual legacy of Jan Hus thanks to John Blahoslav and John Amos Comenius. The diploma thesis deals with the reflection of Master Jan Hus and his work with prominent personalities such as František Martin Pelcl, Josef Dobrovský, Karel Havlicek Borovsky,...
