No Laughing Matter: Shakespearean Melancholy and the Transformation of Comedy

Mon projet de thèse démontre le rôle essentiel que tient la mélancolie dans les comédies de Shakespeare. J’analyse sa présence au travers de multiples pièces, des farces initiales, en passant par les comédies romantiques, jusqu’aux tragicomédies qui ponctuent les dernières années de sa carrière. Je dénote ainsi sa métamorphose au sein du genre comique, passant d’une représentation individuelle se rapportant à la théorie des humeurs, à un spectre émotionnel se greffant aux structures théâtrales dans lesquelles il évolue. Je suggère que cette progression s’apparent au cycle de joie et de tristesse qui forme la façon par laquelle Shakespeare dépeint l’émotion sur scène. Ma thèse délaisse donc les théories sur la mélancolie se rapportant aux humeurs et à la psychanalyse, afin de repositionner celle-ci dans un créneau shakespearien, comique, et historique, où le mot « mélancolie » évoque maintes définitions sur un plan social, scientifique, et surtout théâtrale. Suite à un bref aperçu de sa prévalence en Angleterre durant la Renaissance lors de mon introduction, les chapitres suivants démontrent la surabondance de mélancolie dans les comédies de Shakespeare. A priori, j’explore les façons par lesquelles elle est développée au travers de La Comedie des Erreurs et Peines d’Amour Perdues. Les efforts infructueux des deux pièces à se débarrasser de leur mélancolie par l’entremise de couplage hétérosexuels indique le malaise que celle-ci transmet au style comique de Shakespere et ce, dès ces premiers efforts de la sorte. Le troisième chapitre soutient que Beaucoup de Bruit pour Rien et Le Marchand de Venise offrent des exemples parangons du phénomène par lequel des personnages mélancoliques refusent de tempérer leurs comportements afin de se joindre aux célébrations qui clouent chaque pièce. La mélancolie que l’on retrouve ici génère une ambiguïté émotionnelle qui complique sa présence au sein du genre comique. Le chapitre suivant identifie Comme il vous plaira et La Nuit des Rois comme l’apogée du traitement comique de la mélancolie entrepris par Shakespeare. Je suggère que ces pièces démontrent l’instant où les caractérisations corporelles de la mélancolie ne sont plus de mise pour le style dramatique vers lequel Shakespeare se tourne progressivement. Le dernier chapitre analyse donc Périclès, prince de Tyr et Le Conte d’Hiver afin de démontrer que, dans la dernière phase de sa carrière théâtrale, Shakespeare a recours aux taxonomies comiques élucidées ultérieurement afin de créer une mélancolie spectrale qui s’attardent au-delà des pièces qu’elle hante. Cette caractérisation se rapporte aux principes de l’art impressionniste, puisqu’elle promeut l’abandon de la précision au niveau du texte pour favoriser les réponses émotionnelles que les pièces véhiculent. Finalement, ma conclusion démontre que Les Deux Nobles Cousins représente la culmination du développement de la mélancolie dans les comédies de Shakespeare, où l’incarnation spectrale du chapitre précèdent atteint son paroxysme. La nature collaborative de la pièce suggère également un certain rituel transitif entre la mélancolie dite Shakespearienne et celle développée par John Fletcher à l’intérieure de la même pièce.

Complexity quantification of dense array EEG using sample entropy analysis

n this paper, a time series complexity analysis of dense array electroencephalogram signals is carried out using the recently introduced Sample Entropy (SampEn) measure. This statistic quantifies the regularity in signals recorded from systems that can vary from the purely deterministic to purely stochastic realm. The present analysis is conducted with an objective of gaining insight into complexity variations related to changing brain dynamics for EEG recorded from the three cases of passive, eyes closed condition, a mental arithmetic task and the same mental task carried out after a physical exertion task. It is observed that the statistic is a robust quantifier of complexity suited for short physiological signals such as the EEG and it points to the specific brain regions that exhibit lowered complexity during the mental task state as compared to a passive, relaxed state. In the case of mental tasks carried out before and after the performance of a physical exercise, the statistic can detect the variations brought in by the intermediate fatigue inducing exercise period. This enhances its utility in detecting subtle changes in the brain state that can find wider scope for applications in EEG based brain studies.

Seasonal ramification in the biochemical composition of organic matter in Chalakudy river-estuary

The present study which is the first of its kind in this region is an attempt to generate adequate information on the relative abundances, the seasonal and spatial variations as well as on the source and fate of organic compounds found associated with the dissolved, particulate and sedimentary compartments of Chalakudy river system. The study aimed at investigating variations, the relative proportion of dissolved, particulate and sedimentary fractions of these materials as well as the pollution extent so as to be able to comment on the present condition of this river-estuarine system. This thesis focuses attention on the role of biogeoorganics in modifying the ecological and environmental condition of the dissolved, particuIate and sediment compartments with their minute variability subjected to various physical, chemical and biogeochemical processes. A scheme of study encompassing all these objectives provides the frame work for the present investigation.

Grain boundaries in vortex matter

We explore the statistical properties of grain boundaries in the vortex polycrystalline phase of type-II superconductors. Treating grain boundaries as arrays of dislocations interacting through linear elasticity, we show that self-interaction of a deformed grain boundary is equivalent to a nonlocal long-range surface tension. This affects the pinning properties of grain boundaries, which are found to be less rough than isolated dislocations. The presence of grain boundaries has an important effect on the transport properties of type-II superconductors as we show by numerical simulations: our results indicate that the critical current is higher for a vortex polycrystal than for a regular vortex lattice. Finally, we discuss the possible role of grain boundaries in vortex lattice melting. Through a phenomenological theory we show that melting can be preceded by an intermediate polycrystalline phase.

Momentum distribution in nuclear matter and finite nuclei

A simple method is presented to evaluate the effects of short-range correlations on the momentum distribution of nucleons in nuclear matter within the framework of the Greens function approach. The method provides a very efficient representation of the single-particle Greens function for a correlated system. The reliability of this method is established by comparing its results to those obtained in more elaborate calculations. The sensitivity of the momentum distribution on the nucleon-nucleon interaction and the nuclear density is studied. The momentum distributions of nucleons in finite nuclei are derived from those in nuclear matter using a local-density approximation. These results are compared to those obtained directly for light nuclei like 16O.

Relativistic Thomas-Fermi description of collective modes in droplets of nuclear matter

Isoscalar collective modes in a relativistic meson-nucleon system are investigated in the framework of the time-dependent Thomas-Fermi method. The energies of the collective modes are determined by solving consistently the dispersion relations and the boundary conditions. The energy weighted sum rule satisfied by the models considered allows the identification of the giant resonances. The percentage of the energy weighted sum rule exhausted by the collective modes is in agreement with experimental data, but the agreement with the energy of the modes depends on the model considered.
