Don Juan Manuel’s laudatory portrayal of Saladin, the Muslim Sultan of Babylon, in Exempla 25 and 50 of El Conde Lucanor presents an interesting paradox, particularly when considering that the fourteenth-century text was intended as moral instruction for a Christian audience. This report addresses this paradox by determining Saladin’s placement within Juan Manuel’s moral and spiritual philosophy through textual and comparative character analyses. The first section applies Victor Turner’s social drama theory in a textual analysis of Exempla 25 and 50 to establish Juan Manuel’s representation of Saladin as a triumphant figure, capable of meeting and overcoming challenges to his honor and virtue. The second section applies M. M. Bakhtin’s concept of dialogism to engage in a closer examination of Saladin’s “voice” in relation to other characters of Juan Manuel’s exempla for the purpose of revealing the ambiguities and finer intricacies of Saladin’s character. These analyses serve to raise and address paradoxical questions relating to Juan Manuel’s presentation of Saladin as both a Muslim adversary and friend of Christendom. / text

It has been suggested that these costs can be reduced by the presence of a single large shareholder monitoring management and their decisions. On the contrary it has also been argued that a large shareholder negatively affects firm performance by deriving personal benefits from the firm and making suboptimal decisions. This research aims to investigate the relationship between the profitability of a firm and the level to which the shares of that firm are concentrated into a single shareholder. A random effects GLS panel regression is used to determine the effect of a large shareholder being present in Spanish and Portuguese firms by studying firms listed on these bourses over the period 2005 – 2014. The results show that a large shareholder has a negative influence in the Portuguese market, and no statistically significant effect in the Spanish market / Os custos de agência que resultam essencialmente da separação de poder e controlo de uma empresa, podem contribuir negativamente para a performance e rentabilidade desta. A literatura existente sugere que estes custos podem ser minimizados pela presença de um único grande accionista tendo em conta que pode monitorizar mais de perto os seus gestores e respectivas acções e decisões. Por outro lado, existem vários argumentos em estudos passados que defendem que um grande accionista pode afectar negativamente a performance de uma empresa, privilegiando a sua utilidade em detrimento de decisões que beneficiem a sociedade que controla. Este estudo tem por isso como objectivo investigar a relação entre a rentabilidade, lucro de uma empresa e proporção de acções que está concentrada num único accionista. Uma regressão de efeitos aleatórios de dados painel GLS é usada então para determinar o efeito da presença de grandes accionistas em empresas portuguesas e espanholas, listadas em bolsa no período 2005- 2014. Os resultados mostram que a presença de grandes accionistas tem um impacto negativo no mercado português, ao passo que não existe qualquer evidência significativa no caso espanhol.

La thèse fait l’analyse des références impériales dans la politique mené par d’Alphonse V, roi du Portugal, entre 1448 et 1481. Dans la première partie, nous avons étudié la dilatation de la notion juridique d’imperium sur les territoires maritimes atlantiques et sur les domaines que les portugais, on conquit au Magreb. Dans la deuxième partie, nous avons analysé comment le chroniqueur du roi a présenté le Portugal par rapport aux Empires historiques (Roman et Visigot) et comme la notion de Royaume Élu, d’appel universalistes, ont constitué des références fondamentales à la politique expansionniste.Dans la troisième partie, nous présentons l’analyse des prétentions impériales du roi travers l’analyse de deux aspect de sa politique externe. Le mariage de sa sœur, Léonore du Portugal avec Frédéric II, Habsbourg et son élévation au titre d’impératrice. Le silence sur cette union nous a permis de comprendre que l’idéal impérial cultivé par le roi et sa cour, s’éloignait de la référence romane germanique. Finalement, l’étude sur la guerre mené par le roi contre Isabelle de Castille, future Reine Catholique, pendant la période 1475 et 1479, où le roi du Portugal a essayé d’assumer le gouvernement de la Couronne travers le mariage avec Jeanne et aussi les plans de partage d’Aragon, faites entre Louis XI, roi de France et Alphonse V, explicite son intention d’unifier la péninsule Ibérique, reconstituant l’unité mythique. / This study analyses de imperial aspects of the politics of D. Afonso V, king of Portugal (1448-1481). The first part of the work is composed by the dilatation of the juridical notion of imperium, concerning the atlantics and africans Portuguese possessions. The second part studies how the historian of the king, Zurara, presented Portugal as an heir of the Roman and Visigoth empires and how the notion of elected kingdom, that carries a strong sense of universal monarchy, made part of the fundamental political ideals that sustained the expansion in Africa and at the Atlantic islands.At the last part, we present the imperial intents of the king through the study of his external politic with the Holy Empire and the Crown of Castile. The marriage of the sister’s king, Leonor, with the emperor Frederick II, Habsburg, is the first aspect analysed. The silence about this union gave us means to understand why the ideal of Empire of the Portuguese king was very different of the roman germanic reference. Finally, we study the war between Portugal and Castile, against Isabel, future Catholic queen, during the period 1475 and 1479. The king of Portugal tried to assume the government of the Crown, by marrying Jane, princess and heir of the Castile. Also, the plains signed between Louis XI, king of France and Afonso V, in 1475, shows that the portuguese king and French king intended to prepare a war agains Aragon and share their territories. The politic of Afonso inside Iberia explicated his aim of “re-unify” the hole peninsula under his control.

Les embouchures tidales dominées par la houle sont des systèmes côtiers particulièrement dynamiques dont la morphologie est continuellement remodelée par l’action des vagues et de la marée. Les rapides évolutions morphologiques auxquelles elles sont sujettes impactent directement leurs environnements écologiques et socio-économiques. Afin de mettre en œuvre des réglementations adaptées à la gestion durable des embouchures tidales, des études environnementales systématiques sont nécessaires. L’objectif principal de cette thèse est de mieux comprendre les processus physiques qui contrôlent les évolutions morphologiques d’une embouchure tidale éphémère au Portugal - l’embouchure de la lagune d’Albufeira – à partir de l’analyse de mesures hydrodynamiques et topographiques et de résultats d’un système de modélisation morphodynamique récemment développé. Les processus qui influent sur la dynamique de l’embouchure tidale à court terme, notamment ceux liés aux interactions vague-courant, ont été étudiés à travers l’application du système de modélisation à l’embouchure. Les modulations saisonnières du climat de vagues et du niveau moyen de la mer affectent fortement la dynamique sédimentaire de l’embouchure et contribuent au comblement naturel de l’embouchure pendant l’hiver. Les processus à long terme ont également été étudiés à partir de simulations rétrospectives de paramètres moyens de vagues pour des échelles régionales et locales sur une période 65 ans. Les fortes variabilités interannuelles du climat de vagues et de la dérive littorale qui lui est associée pourraient expliquer les différences d’évolutions morphologiques du système embouchure-lagune sur des échelles de temps pluri–annuels. / Wave-dominated tidal inlets are very dynamic coastal systems, whose morphology is continuously shaped by the combined action of the waves and the tides. The rapid morphological changes they experience impact directly their ecological and socio-economic environments. In order to implement adequate regulations for the sustainable management of tidal inlets, systematic environmental studies are necessary. The main objective of this PhD research work is to gain a better understanding of the physical processes that control the morphological evolutions of an ephemeral tidal inlet in Portugal - the Albufeira Lagoon inlet - based on the analysis of hydrodynamic and topographic data and on the results of a newly developed morphodynamic modelling system. The processes that impact the dynamics of the inlet at short time-scales, particularly those related to wave-current interactions, are investigated through the application of the modelling system to the inlet. The seasonal modulations of the wave climate and mean sea level strongly affect the sediment dynamics of the inlet and contribute to the natural closure of the inlet during the winter period. Long-term processes are also investigated based on a 65-year hindcast of mean wave parameters at regional and local scales. The large inter-annual variability of the wave climate and the associated longshore sediment transport – both correlated to the North-Atlantic Oscillation – are proposed to explain the differences in the morphological behaviour of the inlet-lagoon system at pluri-annual time-scales.

Du Ve s. au Ier s. a.C., l’espace transpyrénéen compris entre l’Èbre et la Garonne, reliant la Méditerranée à l’Atlantique, se situe au carrefour de différentes aires culturelles : la Gaule celtique, la péninsule Ibérique, l’Aquitaine, les cités grecques, mais aussi Rome. En raison du manque de sources littéraires ou de l’insuffisance des données archéologiques, notre connaissance des populations indigènes demeure fragmentaire. Cette lacune ne peut être comblée que par l’étude des vestiges matériels qu’elles nous ont laissés. Aussi, la monnaie peut fournir des données cruciales car elle représente non seulement un témoin privilégié des relations entre communautés protohistoriques, mais constitue également, du fait de sa valeur symbolique, le reflet même de ces sociétés. Il a semblé nécessaire d’aborder le fait monétaire sous un œil nouveau et de se démarquer des approches numismatiques traditionnelles (souvent cloisonnées à des considérations iconographiques et typologiques), dont les interprétations débouchent généralement sur un discours déconnecté des réalités humaines et historiques. La monnaie étant la manifestation d’un état social, ce travail propose d’appréhender sous un angle transdisciplinaire (archéologique, économique, numismatique, statistique et anthropologique) la complexité et la variété des pratiques monétaires. L’une des questions primordiales reste liée à l’apparition du monnayage. Dans cette perspective, il s’est avéré essentiel de déterminer les rythmes, les modalités, et les agents de sa diffusion. Répondant à des origines plurielles, l’introduction de la monnaie dans les échanges implique toute une série de changements structurels dont nous essayons de mesurer l’impact social, économique et politique. D’autre part, une analyse des différents monnayages, nous a mené à caractériser les réalités ethniques, les flux commerciaux, les changements politico-culturels, ainsi que les influences provenant d’environnements plus éloignés. Cette approche a également permis de distinguer des tendances historiques, ainsi que des domaines culturels singuliers. Plus largement, la réflexion se centre sur la place de la monnaie au sein de ces sociétés protohistoriques : quel est son rôle, son importance ? À qui et à quoi sert-elle ? Ces interrogations ont pour objectif de mieux saisir les modalités d’échanges au second âge du Fer. Pour la première fois, ce travail esquisse un panorama monétaire et économique intelligible entre l’apparition des premières espèces monnayées et la mise en place du système monétaire romain. / From the fifth to the first century b.C., the space between the Ebro and the Garonne, which joins the Mediterranean to the Atlantic, is located at the crossroads of various cultural areas : the Celtic Gaul, the Iberian Peninsula, the Aquitaine, the greek cities, as well as Rome. Due to the lack of literary sources and archaeological data, our knowledge of indigenous peoples remains limited. This gap can be filled by the study of archeological materials. Among them, the coinage can provide crucial data because it represents a strong evidence of relations between the different protohistoric communities. In addition to that, owing to its symbolic value, money becomes a genuine expression of protohistoric societies. It seemed necessary to study the coinage in a new light so as to stand out from traditional numismatic approaches often restricted to iconographic and typological considerations. Those interpretations generally lead to a discourse too far from human and historical realities. The coins represent an evidence of a social reality. This work proposes a transdisciplinary point of view (archaeological, economic, numismatics, statistical and anthropological) to learn more about the complexity and the variety of monetary practices. One of the main issues remains the emergence of coinage. In this perspective, it was essential to define rhythms, modes, and also agents involved in its circulation. From various origins, the insertion of money within trade involves a series of structural changes : we try to measure their social, economic and political impacts. On the other hand, an analysis of different coinages drove us to characterize together ethnic realities, trade flows, political and cultural changes, as well as influences coming from more or less distant areas. This approach has also led us to distinguish historical trends and singular cultural fields. More generally, this approach focuses on the role of money in these protohistoric societies : which role does it play, what is its weight? What is it used for and whom does it serve? These questions aim to understand the features of trade during the second Iron Age. For the first time, this work outlines a monetary and economic panorama from the first coining to the advent of the Roman system.
