An application of theory to various reality television shows in order to discuss the emergence and encouragement of the false self in our society is the focus of this work. Toddlers and Tiaras, Hoarders and Sister Wives are the three television shows that will be analyzed by using content analysis in order to examine the effects of consumerism, narcissism and the emergence of the false self. The limitless character of the economy coupled with narcissism and an increased focus on the self contributes to the development of the false self within the individual. People may not even be aware of the push to be narcissistic, focused on our own biographies and self-promotion, yet people are aware of their suffering and unhappiness. Many individuals are left questioning why it is that they are never completely satisfied even as they accumulate notoriety, success, material wealth and possessions. An ideology of greatness and being the best is found in so many avenues of our daily lives, and at times it can be overwhelming, and if we do not possess these skills and qualities we are encouraged to just fake it.

Ce travail prend pour objet la culture matérielle – c'est-à-dire « l'ensemble des phénomènes de co-construction des sujets, du social et de la culture dans le rapport aux objets matériels » (M. Roustan) – des aristocrates de la Renaissance française. Le cas de la maison de Guise permet de dresser un panorama des possessions indispensables à une grande famille du XVIe siècle pour tenir son rang dans la société de cour ; il autorise aussi l'étude de l'impact d'une exigence accrue de paraître sur les finances aristocratiques, et laisse apercevoir les pratiques sociales de consommation. Au-delà de la simple description, ce travail met en évidence les valeurs qui sous-tendaient l'environnement matériel aristocratique ; il révèle aussi la façon dont les objets participèrent à la transformation identitaire de l'élite courtisane de la Renaissance. / This work deals with the material culture – understood as a comprehensive phenomenon which both fashions and is fashioned by society, culture and individuals – of French Renaissance aristocrats. The House of Guise case study unveils the variety of goods a 16th-century great household needed in order to stay in keeping with its rank in the court society. It further reveals the financial consequences for noble houses of the ever-increasing obligation to appear splendidly. The social practices that lay behind shopping are also examined. Beyond a mere description, this work underlines the values embodied in the noble material environment and stresses the part objects took in the redefining of Renaissance elite identity.

According to the dominant approach in the theory of vagueness, the nature of the vagueness of an expression ‘F’ consists in its presenting borderline cases in an appropriately ordered series: objects which are neither definitely F nor definitely not F (where the notion of definiteness can be semantic, ontic, epistemic, psychological or primitive). In view of the various problems faced by theories of vagueness adopting the dominant approach, the thesis proposes to reconsider the naive theory of vagueness, according to which the nature of the vagueness of an expression consists in its not drawing boundaries between any neighbouring objects in an appropriately ordered series. It is argued that expressions and concepts which do present this feature play an essential role in our cognitive and practical life, allowing us to conceptualize—in a way which would otherwise be impossible—the typically coarse-grained distinctions we encounter in reality. Despite its strong initial plausibility and ability to explain many phenomena of vagueness, the naive theory is widely rejected because thought to be shown inconsistent by the sorites paradox. In reply, it is first argued that accounts of vagueness based on the dominant approach are themselves subject to higher-order sorites paradoxes. The paradox is then solved on behalf of the naive theory by rejecting the unrestricted transitivity of the consequence relation on a vague language; a family of logics apt for reasoning with vague expressions is proposed and studied (using models with partially ordered values). The characteristic philosophical and logical consequences of this novel solution are developed and defended in detail. In particular, it is shown how the analysis of what happens in the attempt of surveying a sorites series and deciding each case allows the naive theory to recover a "thin" notion of a borderline case.

[EN] The presence of surveillance systems in our lives has drastically increased during the last years. Camera networks can be seen in almost every crowded public and private place, which generate huge amount of data with valuable information. The automatic analysis of data plays an important role to extract relevant information from the scene. In particular, the problem of person re-identification is a prominent topic that has become of great interest, specially for the fields of security or marketing. However, there are some factors, such as changes in the illumination conditions, variations in the person pose, occlusions or the presence of outliers that make this topic really challenging. Fortunately, the recent introduction of new technologies such as depth cameras opens new paradigms in the image processing field and brings new possibilities. This Thesis proposes a new complete framework to tackle the problem of person re-identification using commercial rgb-depth cameras. This work includes the analysis and evaluation of new approaches for the modules of segmentation, tracking, description and matching. To evaluate our contributions, a public dataset for person re-identification using rgb-depth cameras has been created. Rgb-depth cameras provide accurate 3D point clouds with color information. Based on the analysis of the depth information, an novel algorithm for person segmentation is proposed and evaluated. This method accurately segments any person in the scene, and naturally copes with occlusions and connected people. The segmentation mask of a person generates a 3D person cloud, which can be easily tracked over time based on proximity. The accumulation of all the person point clouds over time generates a set of high dimensional color features, named raw features, that provides useful information about the person appearance. In this Thesis, we propose a family of methods to extract relevant information from the raw features in different ways. The first approach compacts the raw features into a single color vector, named Bodyprint, that provides a good generalisation of the person appearance over time. Second, we introduce the concept of 3D Bodyprint, which is an extension of the Bodyprint descriptor that includes the angular distribution of the color features. Third, we characterise the person appearance as a bag of color features that are independently generated over time. This descriptor receives the name of Bag of Appearances because its similarity with the concept of Bag of Words. Finally, we use different probabilistic latent variable models to reduce the feature vectors from a statistical perspective. The evaluation of the methods demonstrates that our proposals outperform the state of the art. / [ES] La presencia de sistemas de vigilancia se ha incrementado notablemente en los últimos anños. Las redes de videovigilancia pueden verse en casi cualquier espacio público y privado concurrido, lo cual genera una gran cantidad de datos de gran valor. El análisis automático de la información juega un papel importante a la hora de extraer información relevante de la escena. En concreto, la re-identificación de personas es un campo que ha alcanzado gran interés durante los últimos años, especialmente en seguridad y marketing. Sin embargo, existen ciertos factores, como variaciones en las condiciones de iluminación, variaciones en la pose de la persona, oclusiones o la presencia de artefactos que hacen de este campo un reto. Afortunadamente, la introducción de nuevas tecnologías como las cámaras de profundidad plantea nuevos paradigmas en la visión artificial y abre nuevas posibilidades. En esta Tesis se propone un marco completo para abordar el problema de re-identificación utilizando cámaras rgb-profundidad. Este trabajo incluye el análisis y evaluación de nuevos métodos de segmentación, seguimiento, descripción y emparejado de personas. Con el fin de evaluar las contribuciones, se ha creado una base de datos pública para re-identificación de personas usando estas cámaras. Las cámaras rgb-profundidad proporcionan nubes de puntos 3D con información de color. A partir de la información de profundidad, se propone y evalúa un nuevo algoritmo de segmentación de personas. Este método segmenta de forma precisa cualquier persona en la escena y resuelve de forma natural problemas de oclusiones y personas conectadas. La máscara de segmentación de una persona genera una nube de puntos 3D que puede ser fácilmente seguida a lo largo del tiempo. La acumulación de todas las nubes de puntos de una persona a lo largo del tiempo genera un conjunto de características de color de grandes dimensiones, denominadas características base, que proporcionan información útil de la apariencia de la persona. En esta Tesis se propone una familia de métodos para extraer información relevante de las características base. La primera propuesta compacta las características base en un vector único de color, denominado Bodyprint, que proporciona una buena generalización de la apariencia de la persona a lo largo del tiempo. En segundo lugar, se introducen los Bodyprints 3D, definidos como una extensión de los Bodyprints que incluyen información angular de las características de color. En tercer lugar, la apariencia de la persona se caracteriza mediante grupos de características de color que se generan independientemente a lo largo del tiempo. Este descriptor recibe el nombre de Grupos de Apariencias debido a su similitud con el concepto de Grupos de Palabras. Finalmente, se proponen diferentes modelos probabilísticos de variables latentes para reducir los vectores de características desde un punto de vista estadístico.

It is a generally accepted scholarly truth that Shakespeare’s Macbeth was written with the intent of pleasing the newly crowned James I, a few years after his ascension to the English throne in 1603. The main arguments for this claim are, first, Shakespeare’s inclusion of witches—a well-known interest of James’s—and second, the portrayal of Banquo, the fictional ancestor of the House of Stuart. Some recent scholarship has, however, questioned this view, arguing, among other things, that James did not wish to be associated with his Scottish heritage and that witchcraft is not as prominent in Shakespeare’s play as it might have been if pleasing James was his objective. In this paper, I look specifically at the part of the theory of “the royal play” which pertains to the question of the witches and, against the background of this recent research, argue that Shakespeare’s reasons for including witches in his play have less to do with James and more to do with his own interest in human psychology. By analysing the ways in which Shakespeare adapts his sources—the chronicles of Raphael Holinshed and Hector Boece—I argue, first, that Shakespeare is less interested in catering specifically to James’s demonological theories than to make the three women into witches as such. Secondly, I compare the function of prophecy in Macbeth to Greek tragedy and the historical writing of Holinshed and Boece against the sociological theory of George Park and argue that Shakespeare’s purpose in letting witches function as the deliverers of prophecy is to create an element of uncertainty and thus a vantage point from which to explore the psychological complexities of human decision-making and the perils of trusting appearances.

Από τις εμφανίσεις φαντασμάτων στην αρχαιοελληνική λογοτεχνία, άλλες παρουσιάζονται ως ιστορικά γεγονότα, όπως οι εμφανίσεις φαντασμάτων στον Ηρόδοτο, ενώ άλλες υπηρετούν τους σκοπούς του δημιουργού, ενσωματωμένες σε αμιγώς λογοτεχνικά έργα. Η έρευνά μας, επικεντρωμένη στην δεύτερη ομάδα, εξετάζει επιφάνειες φαντασμάτων στον Όμηρο και την αττική τραγωδία, συγκεκριμένα δε αυτές του Πατρόκλου (Ἰλ. Ψ 59-108), του Δαρείου (Πέρσ. 598-842), της Κλυταιμήστρας (Εὐμεν. 94-139) και του Πολυδώρου (Ἑκ. 1-58). Η επιλογή των συγκεκριμένων περιπτώσεων υπαγορεύεται αφενός από την προαναφερθείσα κοινή λογοτεχνική φύση τους, και αφετέρου από την ομοιότητα στα χαρακτηριστικά των σκηνών, δηλαδή των συνθηκών εμφάνισης (χρόνος, χώρος, κατάσταση του ζωντανού δέκτη), της όψης και της συμπεριφοράς των φαντασμάτων (άυλη εμφάνιση, διατήρηση της μορφής, γνωστικό επίπεδο των φαντασμάτων) και της λειτουργίας τους ως λογοτεχνικών χαρακτήρων. Ειδικότερα, ως προς τις συνθήκες εμφάνισης παρατηρείται ισχυρή σύνδεση των φασματικών χαρακτήρων με την νύχτα και τα όνειρα, με την μοναχικότητα του ζωντανού στον οποίο εμφανίζονται, ενώ ο τόπος της εμφάνισης καθορίζεται σε μεγάλο βαθμό από την ευχέρεια που παρέχει στο φάντασμα να επιτύχει την ικανοποίηση των αιτημάτων του. Αναφορικά με την όψη και την συμπεριφορά τους, η έρευνα αποκάλυψε ότι, παρά την άυλη φύση τους (γνωστή ήδη από τους ακυρωμένους εναγκαλισμούς Αχιλλέα-Πατρόκλου στην Ἰλιάδα και Οδυσσέα-Αντίκλειας στην Ὀδύσσεια), οι ψυχές των νεκρών διατηρούν την μορφή του ζωντανού εαυτού τους, ενίοτε φέροντας και τα θανατηφόρα τραύματά τους. Κατά παρόμοιο τρόπο, η συνομιλία μαζί τους εκτυλίσσεται συνήθως σε φυσιολογικές συνθήκες, σαν να πρόκειται δηλαδή για ζωντανό, με εξαίρεση την άγνοιά τους για ορισμένα γεγονότα του Επάνω κόσμου, κυρίως για όσα έχουν συμβεί κατά την παραμονή τους στον Άδη. Τέλος, το αίτημα του φαντάσματος για ταφή ή εκδίκηση εις βάρος του δολοφόνου του (παράμετροι που καθορίζουν σε μεγάλο βαθμό την εμφάνιση), αποσκοπεί στην αποκατάσταση της τάξης (όσον αφορά το ίδιο το φάντασμα και την διαχείριση του νεκρού σώματός του) και, συνεπώς, προωθεί την πλοκή. / Of the appearances of ghosts in the ancient Greek literature, some are incorporated in historical works (such as in the work of Herodotus), whereas others are part of sheer literary works. Our dissertation focuses on four instances from the second category: the ghosts of Patroclus (Iliad 23.59-108), Darius (Aesch. Persae 598-842), Clytemnestra (Aesch. Eumenides 94-139) and Polydorus (Eurip. Hecuba 1-58). The selection of these instances is not only based on their literary context, but mainly on the correspondence on the matters of conditions, in which they make their appearance, on their look and behaviour and, finally, on their function. Particularly, it seems that there is a close connection between ghosts and the night and dreams, as well as with the loneliness of the living person, who meets them. They also seem to appear in places that facilitates the fulfillment of their demand. As for their look, despite their insubstantial nature (known already from the Iliad and Odyssey), the ghosts maintain the appearance of their body, in the case of the biaiothanatoi bearing the wounds, that caused their death. Their knowledge of the Upper World varies, as they sometimes ignore facts, which have happened after their death. Finally, their demand for burial or vengeance against their murderers aims to the instauration of order and, because of its importance, advances the plot.
