Dénombrement dans les empilements apolloniens généralisés et distribution angulaire dans les extensions quadratiques imaginaires.

Cette thèse traite de deux thèmes principaux. Le premier concerne l'étude des empilements apolloniens généralisés de cercles et de sphères. Généralisations des classiques empilements apolloniens, dont l'étude remonte à la Grèce antique, ces objets s'imposent comme particulièrement attractifs en théorie des nombres. Dans cette thèse sera étudié l'ensemble des courbures (les inverses des rayons) des cercles ou sphères de tels empilements. Sous de bonnes conditions, ces courbures s'avèrent être toutes entières. Nous montrerons qu'elles vérifient un principe local-global partiel, nous compterons le nombre de cercles de courbures plus petites qu'une quantité donnée et nous nous intéresserons également à l'étude des courbures premières. Le second thème a trait à la distribution angulaire des idéaux (ou plutôt ici des nombres idéaux) des corps de nombres quadratiques imaginaires (que l'on peut voir comme la distribution des points à coordonnées entières sur des ellipses). Nous montrerons que la discrépance de l'ensemble des angles des nombres idéaux entiers de norme donnée est faible et nous nous intéresserons également au problème des écarts bornés entre les premiers d'extensions quadratiques imaginaires dans des secteurs.

A dança dos monstros: corpo e estética na arte e na Educação Física

The speeches about the body in interface with the technology, that fulfill the contemporary discussions, have been a stage of innumerable ethical, epistemological, aesthetic and ontological reflections. These happened bodies of the biotechnological scene also invade the dance, making several possible dialogues, making old concepts instable, opening way to revealing explorations and bringing with it implications and reflections. In this context, this research has as objective to discuss relations between body and technology in the dance; to understand the aesthetic configurations of the monster in the dance as possibility to question the body; to establish relations between the monstrous body in the dance and the conceptions of body in the Physical Education. We believe to be able to contribute for the reflection in the field of the Physical Education, since the work visualizes to extend the field of the discussions on aesthetic body and, as well as evidencing dialogues between different areas of the knowledge, as the Art and the Physical Education. From the point of view of the method, the work follows orientation of the Phenomenology for an aesthetic image appreciation of the videos in the choreographies In'perfeito and Violência of Cena 11, Dance Group that has marked new aesthetic configurations in the brazilian dance. Thus, we took for us the reflections on the "significant scenes" proposed by Bicudo (2000), to appreciate the dance of Cena 11. We emphasize that, after the identification of the Significant Scenes, it was necessary to approach these scenes from close senses, from which we detach the appearance, the space and the gesture. We evidence that, the bodies revealed by the group Cena 11, show an aesthetic that it interlaces the beauty, the ugly and the grotesque. An aesthetic of the unharmony, capable to transgress the oppositions, dialoguing with multiple antagonisms and that it amplifies the apollonian aesthetic linear rules, so predominant in the history of the dance and the Physical Education. We identify some indicatives that take us to the problematizations on an affective and anarchic body, when questioning the tyranny of the perfect corporality; the naturalization of the pain; the closed gesture in a finished and unique grammar; the standardization of feminine and masculine roles and the negation of the feeling. From these indicatives, we discuss the aesthetic of the deformed bodies of Cena 11, approaching it of the conceptions of body in the Physical Education, sometimes criticizing the rationalists and naturalistic views, sometimes dialoguing with more recent perspectives studied by researchers of this area of knowledge, which point to a reflection on the body under the optics of the sensible

Annealed Ising model on hierarchical structures: a transfer matrix approach.

Spin systems in the presence of disorder are described by two sets of degrees of freedom, associated with orientational (spin) and disorder variables, which may be characterized by two distinct relaxation times. Disordered spin models have been mostly investigated in the quenched regime, which is the usual situation in solid state physics, and in which the relaxation time of the disorder variables is much larger than the typical measurement times. In this quenched regime, disorder variables are fixed, and only the orientational variables are duly thermalized. Recent studies in the context of lattice statistical models for the phase diagrams of nematic liquid-crystalline systems have stimulated the interest of going beyond the quenched regime. The phase diagrams predicted by these calculations for a simple Maier-Saupe model turn out to be qualitative different from the quenched case if the two sets of degrees of freedom are allowed to reach thermal equilibrium during the experimental time, which is known as the fully annealed regime. In this work, we develop a transfer matrix formalism to investigate annealed disordered Ising models on two hierarchical structures, the diamond hierarchical lattice (DHL) and the Apollonian network (AN). The calculations follow the same steps used for the analysis of simple uniform systems, which amounts to deriving proper recurrence maps for the thermodynamic and magnetic variables in terms of the generations of the construction of the hierarchical structures. In this context, we may consider different kinds of disorder, and different types of ferromagnetic and anti-ferromagnetic interactions. In the present work, we analyze the effects of dilution, which are produced by the removal of some magnetic ions. The system is treated in a “grand canonical" ensemble. The introduction of two extra fields, related to the concentration of two different types of particles, leads to higher-rank transfer matrices as compared with the formalism for the usual uniform models. Preliminary calculations on a DHL indicate that there is a phase transition for a wide range of dilution concentrations. Ising spin systems on the AN are known to be ferromagnetically ordered at all temperatures; in the presence of dilution, however, there are indications of a disordered (paramagnetic) phase at low concentrations of magnetic ions.

Resisting Postmodernity: Swedish social policy in the 1990s

The purpose of this paper is to introduce ideas that have emerged during the course of writing a book on Swedish welfare in the 1990s. The book is the result of many years of writing about two subjects: Swedish drug policy and the Swedish welfare state. The one very specialised, the other, more general. I first became interested in Swedish drug policy on a research visit to Örebro Län in 1986. A social worker showed me a copy of the county's drug policy programme and explained the significance of the 'restrictive line'. I have spent the years since that visit, trying to understand and explain the Swedish goal of a drug-free society (Gould 1988, 1994, 1996b). I only began to write about the welfare state in Sweden in the early 1990s, just as things were beginning to go wrong for the economy (Gould 1993a, 1993b, 1996a, 1999). For the last few years I have intended to write a book on the events covered by the period 1991-1998 - the years of a Bourgeois and a Social Democratic Government -which would bring the two halves of my work together. Material for this study has been accumulated over many years. A number of research visits have been made; large numbers of academics, politicians, civil servants, journalists, unemployed people, social workers and their clients have been interviewed; and extensive use has been made of academic, administrative and public libraries. Since September 1991 I have systematically collected articles from Dagens Nyheter about social services, social insurance, health care, employment, social issues and problems, the economy and politics. The journal Riksdag och Departement (Parliament and Ministry), which summarises a wide range of public documents, has been invaluable. Friends and informal contacts have also given me insights into the Swedish way of life. The new book is based upon all of these experiences. This paper will begin with a brief account of major global social and economic changes that have occurred in the last twenty years. This is intended to provide a background to the more recent changes that have occurred in Swedish society in the last decade. It will be suggested that the changes in Sweden, particularly in the field of welfare, have been less severe than elsewhere and that this is due to political, institutional and cultural resistance. The paper will conclude by arguing that Sweden, as an exemplar of an Apollonian modern society, has had much to fear from the Dionysian characteristics of postmodernity.

As téchnai da cidade e a competência do filósofo

El propósito de esta comunicación es examinar la competencia del filósofo en el texto que hoy conocemos como Primer Alcibíades o Alcibíades Mayor. El trabajo propone la lectura del diálogo como un texto de filosofía política. La hipótesis sostenida es que el diálogo fue escrito con la intención de explicar la filosofía como una forma de intervenir políticamente basada en la exégesis filosófica de la sentencia apolínea "Conócete a ti mismo". Se argumenta que la perspectiva del texto se fundamenta en el principio de que la frase lleva consigo una exhortación a ejercer la política de manera recta. El diálogo, pues, no sólo contiene un análisis filosófico sobre la competencia adecuada para el ejercicio del poder, sino que también analiza cómo esta competencia se relaciona con la política, lo que pone a la filosofía en conflicto con las téchnai practicadas en la ciudad

El catolicismo dionisíaco en la "Casa Grande" de Gilberto Freyre

Casa Grande y Senzala, obra cumbre del sociólogo brasileño Gilberto Freyre, ha guiado de una u otra forma el recorrido seguido por la gran mayoría de los estudios históricos abocados al sistema patriarcal del ingenio azucarero. El presente trabajo propone un análisis del catolicismo brasileño durante el período esclavista, en el contexto de una reinterpretación de la obra de Freyre en función del antagonismo entre las categorías de apolíneo y dionisíaco. Esta religiosidad brasileña se nos presentará así como una experiencia eminentemente dionisíaca, frente al carácter apolíneo de la ortodoxia cristiana, y un elemento clave dentro del modelo planteado por Freyre
