Le, Caisne Léonore. "Condamnés à une moyenne ou longue peine : une ethnographie de la vie carcérale à la maison centrale de Poissy". Paris 10, 2000. http://www.theses.fr/2000PA100064.
Testo completoAbstract (sommario):
Cette these presente l'impossible construction identitaire du condamne a une moyenne ou longue peine. A partir d'un travail de terrain realise a la maison centrale de poissy deux annees durant, tant aupres des detenus que du personnel, nous avons degage les figures morales (le << braqueur >>, le << stup >>, le << pointeur >>, le << perpete >>, le << dps >>, le << sale type >>, le << mec bien >>. . . ) et la logique generale d'opposition a la societe et a l'institution que les condamnes doivent partager et suivre pour survivre a l'enfermement et a leur promiscuite. Sur cette logique d'opposition vient buter la logique de conformisation aux citoyens que le personnel leur enjoint de suivre : les detenus doivent << evoluer >>. Ainsi, dans cet espace clos, pris dans la surveillance perpetuelle tant des codetenusque du personnel, le condamne est pris dans des injonctions contradictoires, source de disjonctions identitaires. Il est contraint de mener une double vie, de fragmenter ses discours et ses comportements, de se morceler. Ce qui est aussi un moyen de sauvegarder son intimite. Mais a trop se morceler, il risque aussi de ne plus savoir qui il est.

Testo completoAbstract (sommario):
Avec Les Tragiques, Aubigné démolit les accusations de sédition et d’hérésie véhiculées sur le compte des huguenots par Ronsard. Surgissent entre cette œuvre et les Discours des clivages politiques et religieux où la création poétique est, pour le compte du camp de chaque poète, le moyen de favoriser quelques dispositions sur les allocutaires. La question de la réception occupe ainsi une place centrale dans ces deux œuvres antagonistes. Elle pose le problème de l’enrôlement. Celui-ci est un ensemble de ressources rhétoriques dont l’enjeu consiste à convaincre l’adversaire de ses erreurs, à raffermir les partisans et à conquérir l’opinion publique. Quelles sont ces ressources qui permettent à Ronsard et à Aubigné d’inscrire leurs allocutaires dans des rôles précis en faveur de leurs partis respectifs ? Dans notre thèse, nous nous sommes intéressés aux questions suivantes : sous quels traits éthiques Ronsard et Aubigné parlent-ils chacun pour subordonner ses allocutaires à ses convictions ? Qui sont ces allocutaires ? Avec quels procédés discursifs les deux poètes agissent-ils sur les pensées et sur les comportements de ces destinataires ? Vers les thèses de quel poète risque de se pencher les lecteurs ? Avec ces questions, nous avons observé les rôles de la représentation de l’énonciateur et ses figures dans le discours d’enrôlement, les catégories d’allocutaires et les styles oratoires mis en marche pour produire la persuasion, le raffermissement et la mobilisationWith The Tragics, Aubigné demolishes the accusations of sedition and heresy conveyed on the account of the Huguenots by Ronsard. Arises between this work and the Discourses of political and religious cleavages where the poetic creation is, on behalf of the camp of each poet, the means to favor some provisions on the allocutaries. The question of reception thus occupies a central place in these two antagonistic works. It poses the problem of enlistment. This is a set of rhetorical resources whose challenge is to convince the adversary of his mistakes, to strengthen the partisans and to conquer public opinion. What are these resources that allow Ronsard and Aubigné to put their speakers in specific roles for their respective parties ?In our thesis, we are interested in the following questions : under what ethical traits do Ronsard and Aubigné speak each to subordinate his allocutaries to his convictions ? Who are these allocutaries ? With what discursive processes do the two poets act on the thoughts and behaviors of these recipients? Towards the theses of what poet is likely to lean readers ?With these questions, we have observed the roles of the enunciator's representation and his figures in the enlistment discourse, the categories of allocutaries and the oratorical styles set in motion to produce persuasion, firmness and mobilization

Peukert, Amanda. "Poison". Thesis, California State University, Long Beach, 2018. http://pqdtopen.proquest.com/#viewpdf?dispub=10785348.
Testo completoAbstract (sommario):
POISON is a collection of loosely interrelated short stories chronicling one family’s struggles with drugs, alcohol, poverty, gang affiliation, death, disease, and depravity in Los Angeles, California. Most of the stories are set in the 1990s, and channel the trends of the decade, especially those specific to LA. The chronology of the collection is scattered, the dates and details inconsistent or conflicting. POISON aims to emphasize the imperfect nature of memory, the ways in which recollection at once dictates our lives as well as dismantles it. The collection is accompanied by a fictional family tree and a nonfictional photo album containing real photographs of the semi-fictionalized characters depicted throughout the stories. While the photos may display a sense of contentment, when coupled with the collection’s content, the reader may begin to interrogate the ways in which memory severely skews reality.

Ahmed, Nabil. "Earth poison". Thesis, Goldsmiths College (University of London), 2015. http://research.gold.ac.uk/19404/.
Testo completoAbstract (sommario):
This thesis explores the complex entanglements of natural and human violence by looking at three related cases: 1) the Bhola cyclone in Bangladesh in which a national struggle, genocide and extreme weather interacted; 2) the legal history and geography of arsenic – one of the deadliest earth poisons, whose identification was crucial in the formation of the forensic science of toxicology; and 3) a mine that takes part in the global circulation of resources that is at the same time a site of human rights/environmental violations. The thesis moves from Bangladesh to Victorian England to West Papua to show specific, malign interactions of environment and human action and examine the way they demand new political and juridical responses. The thesis is a practice-based exploration that combines analysis, theory, narrative, film, map and image. This multitudinous and creative method is essential in order to foreground a violence that is registered on multiple dimensions and territories, both seen and unseen. But it is especially important because the third corner of the triangle that holds the thesis together is an engagement with image making, sensing and aesthetics. The environmental violence I describe in this thesis requires a reconceptualisation of theoretical, historical, legal and aesthetic frames. In the case of the Bhola cyclone, it revealed one of the original moments of humanitarian reason and call for the refraction of humanitarianism. Two new, opposite types of response that are still with us are explored: on the one hand the humanitarian benefit concert and, on the other, military intervention propounded as a means to stop genocide. It is in response to these diffused causalities, involving human and nonhuman actors alike, that the legal forums of the future must emerge.

Lecoutre, César. "Polynomial Poisson algebras : Gel'fand-Kirillov problem and Poisson spectra". Thesis, University of Kent, 2014. https://kar.kent.ac.uk/47941/.
Testo completoAbstract (sommario):
We study the fields of fractions and the Poisson spectra of polynomial Poisson algebras. First we investigate a Poisson birational equivalence problem for polynomial Poisson algebras over a field of arbitrary characteristic. Namely, the quadratic Poisson Gel'fand-Kirillov problem asks whether the field of fractions of a Poisson algebra is isomorphic to the field of fractions of a Poisson affine space, i.e. a polynomial algebra such that the Poisson bracket of two generators is equal to their product (up to a scalar). We answer positively the quadratic Poisson Gel'fand-Kirillov problem for a large class of Poisson algebras arising as semiclassical limits of quantised coordinate rings, as well as for their quotients by Poisson prime ideals that are invariant under the action of a torus. In particular, we show that coordinate rings of determinantal Poisson varieties satisfy the quadratic Poisson Gel'fand-Kirillov problem. Our proof relies on the so-called characteristic-free Poisson deleting derivation homomorphism. Essentially this homomorphism allows us to simplify Poisson brackets of a given polynomial Poisson algebra by localising at a generator. Next we develop a method, the characteristic-free Poisson deleting derivations algorithm, to study the Poisson spectrum of a polynomial Poisson algebra. It is a Poisson version of the deleting derivations algorithm introduced by Cauchon [8] in order to study spectra of some noncommutative noetherian algebras. This algorithm allows us to define a partition of the Poisson spectrum of certain polynomial Poisson algebras, and to prove the Poisson Dixmier-Moeglin equivalence for those Poisson algebras when the base field is of characteristic zero. Finally, using both Cauchon's and our algorithm, we compare combinatorially spectra and Poisson spectra in the framework of (algebraic) deformation theory. In particular we compare spectra of quantum matrices with Poisson spectra of matrix Poisson varieties.

The need to model the quantum effects in semiconductor devices such as resonance tunneling diodes and quantum dots has lead to an intense study of the Wigner-Poisson (WP) and Schroedinger-Poisson (SP) systems. In this work we present the mathematical analysis of several related models for these systems. These include: a time-dependent model of dissipation in (SP), a quasi-linear (SP) system, a study of the stationary (WP)-(SP) problem with a discussion of the quantum analogue of classical BGK modes and a proof of existence of eigenfunctions for (SP) with periodic boundary conditions, and an examination of the stationary Wigner equations with inflow" boundary conditions. Finally, a proposed numerical scheme for the stationary (SP) system with Boltzmann distribution functions is shown along with its corresponding Bloch equation.Ph. D.

Testo completoAbstract (sommario):
A hierarchy of vector fields (master symmetries) and homogeneous nonlinear Poisson structures associated with the Toda lattice are constructed and the various connections between them are investigated. Among their properties: new brackets are generated from old ones by using Lie-derivatives in the direction of certain vector fields; the infinite sequences obtained consist of compatible Poisson brackets in which the constants of motion for the Toda lattice are in involution. The vector fields in the construction are unique up to addition of a Hamiltonian vector field. Similarly the Poisson brackets are unique up to addition of a trivial Poisson bracket. These are Poisson tensors generated by wedge products of Hamiltonian vector fields. The non-trivial brackets may also be obtained by the use of r-matrices; we give formulas and prove this for the quadratic and cubic Toda brackets. We also indicate how these results can be generalized to other (semisimple) Toda flows and we give explicit formulas for the rank 2 Lie algebra of type B₂. The main tool in this calculation is Dirac's constraint bracket formula. Finally we study nonlinear Poisson brackets associated with orbits through nilpotent conjugacy classes in gl(n, R) and formulate some conjectures. We determine the degree of the transverse Poisson structure through such nilpotent elements in gl(n, R) for n ≤ 7. This is accomplished also by the use of Dirac's bracket formula.

Testo completoAbstract (sommario):
The focus of this thesis is to introduce the concept of Kähler-Poisson algebras as analogues of algebras of smooth functions on Kähler manifolds. We first give here a review of the geometry of Kähler manifolds and Lie-Rinehart algebras. After that we give the definition and basic properties of Kähler-Poisson algebras. It is then shown that the Kähler type condition has consequences that allow for an identification of geometric objects in the algebra which share several properties with their classical counterparts. Furthermore, we introduce a concept of morphism between Kähler-Poisson algebras and show its consequences. Detailed examples are provided in order to illustrate the novel concepts.The series name is corrected in the electronic version of the cover.

Arnal, Céline. "Ecologie comportementale de la symbiose poisson nettoyeur/poisson client : motivations et honnêteté". Perpignan, 2000. http://www.theses.fr/2000PERP0379.
Testo completoAbstract (sommario):
La symbiose de nettoyage implique un poisson "nettoyeur" qui nettoie le corps de poissons "clients". Cette relation a lieu dans le territoire du poisson nettoyeur : la station de nettoyage. Les nettoyeurs intègrent, lors de leur inspection, des ectoparasites, des écailles et du mucus. Malgré le nombre croissant d'études sur la symbiose de nettoyage, le gain énergétique net issu de cette relation pour les deux protagonistes reste encore à déterminer. Il apparaît ainsi difficile de définir précisement la véritable nature de la relation. Dans ce travail, deux questions principales ont été posées : 1)quels facteurs influencent la symbiose de nettoyage?, et 2) les nettoyeurs sont-ils honnêtes? Quatre espèces de nettoyeurs, issus de trois localités différentes, ont été étudiés : Symphodus melanocercus (Banyuls-sur- Mer), Labroides dimidiatus (Lizard Isaland et Moorea), et les gobies Elacatinus evelynae et Elacatinus prochilos (La Barbade). Une approche de terrain a été utilisée, avec des observations comportementales, des mesures de l'alimentation des nettoyeurs, du parasitisme et des caractéristiques du mucus de leurs clients. Suite à l'étude de chacune des espèces, une comparaison inter-spécifique a été effectuée. L'honnêteté apparaît comme une stratégie importante dans la relation de nettoyage. Ce sont les clients les plus parasités qui visitent le plus les stations de leurs clients. L'honnêteté des nettoyeurs peut, cependant, varier en fonction de plusieurs facteurs comme : l'abondance en ectoparasites, la sexualité, et la localisation de la station de nettoyage. Enfin, il apparaît que chaque espèce de nettoyeur est caractérisée par une spécialisation trophique déterminée, et que les nettoyeurs tropicaux sont plus spécialistes que les nettoyeurs de régions tempéréesCleaning symbiosis involves a cleaner fish, which cleams the body surface of client fishes. The relationship generally occurs in the cleaner territory : the cleaning station, Cleaner fishes remove ectoparasites, scales and mucus when inspecting their client fishes. Despite years of studies, the net fitness of the two protagonists are still not fully understood. It is, thus, difficult to define clearly this relationship. In this study, two main questions have been asked : 1)what factors influence cleaning interactions? and 2) is the cleaner fish behaviour honest? Four species of cleaner fishes from three localities were studied : Symphodus melanocercus (Banyuls-sur- Mer), Labroides dimidiatus (Lizard Isaland et Moorea), and the gobies Elacatinus evelynae and Elacatinus prochilos (Barbados). Field work experiments were conducted through behavioural observations, and direct measurement of cleaners' diet, clients' ectoparasitim and mucus characteristics. Each species was studied separately, and a comparative analysis was performed. Honesty appears to be an important strategy in cleaning symbioses. The most parasited clients visit cleaning stations higher rates, and ectoparasites are the major items removed by cleaner fishes. Cleaner fish honesty shows variations, depending on ectoparasites density, sex, and the localisation of the cleaning station. Finally, cleaning specialisation appears to be species-specific, which more specialised cleaners in tropical than in temperate waters

Testo completoAbstract (sommario):
Multivariate mixed Poisson processes are special multivariate counting processes whose coordinates are, in general, dependent. The first part of this thesis is devoted to properties which multivariate counting processes may possess. Such properties are, for example, the Markov property, the multinomial property and regularity. With regard to regularity we study the properties of transition probabilities and intensities. The second part of this thesis restricts the class of all multivariate counting processes by additional assumptions leading to different types of multivariate mixed Poisson processes which, however, are connected with each other. Using a multivariate version of the Bernstein-Widder theorem, it is shown that multivariate mixed Poisson processes are characterized by the multinomial property. Furthermore, regularity of multivariate mixed Poisson processes and properties of their moments are studied in detail. Throughout this thesis, two types of stability of properties of multivariate counting processes are studied: It is shown that most properties of a multivariate counting process are stable under certain linear transformations including the selection of single coordinates and summation of all coordinates. It is also shown that the different types of multivariate mixed Poisson processes under consideration are in a certain sense stable in time.

In this dissertation, we identify a subgroup Tˢ of Dˢ(μ), the group of Sobolev symplectomorphisms of CP (n), n = 1,2 that has all the properties of a torus of a compact finite dimensional Lie group. We prove that Tˢ: (1) topologically is a submanifold of Dˢ(μ); (2) algebraically is a maximal abelian subgroup of Dˢ(μ); (3) geometrically is flat and totally geodesic. We also characterize the doubly stochastic operators on measurable spaces and use this result to extend the convexity Theorem of T. Bloch, H. Flaschka and T. Ratiu.

Thesis advisor: Susan MichalczykAfter the fall of the Soviet Union and the end of the Cold War, the United States became the one remaining superpower at the head of a unipolar international system. This new position and the repercussions of its power led to the rocky international stability of the 1990s. The Poison Umbrella Effect is a political allegory which explores this historic transition period through the relationships of college students. Anna Bennet is a freshman at Warren College who, after being elected Hall President by default, must find a balance between her friendships and her sense of power and responsibility. Her first year of college is marked by drama, disillusionment, and progress as she develops into the person she will be for the rest of her college career. With her friends representing other countries, and all of their actions representing political events of the 1990s, Anna's experiences demonstrate America's progression from a leading power in a bipoloar world, to the domineering superpower it is today

Testo completoAbstract (sommario):
Il tema centrale di questa tesi è lo studio del problema di Dirichlet per il Laplaciano in R^2 usando le serie di Fourier. Il problema di Dirichlet per il Laplaciano consiste nel determinare una funzione f armonica e regolare in un dominio limitato D quando sono noti i valori che f assume sul suo bordo. Ammette una sola soluzione, ma non esistono criteri generali per ricavarla. In questa tesi si mostra come la formula integrale di Poisson, sotto determinate condizioni, risolva il problema di Dirichlet in R^2 e in R^n.

Isometsä, J. (Juho). "Vesiliukoisten komponenttien poisto tuhkasta". Bachelor's thesis, University of Oulu, 2017. http://urn.fi/URN:NBN:fi:oulu-201704251591.
Testo completoAbstract (sommario):
Tämän kokeellisen kandidaatintyön tavoitteena oli tutkia kahden erityyppisen tuhkamateriaalin, sidosaineena toimivan masuunikuonan ja näiden yhdistelmien soveltuvuutta geopolymeerien raaka-aineeksi sen jälkeen, kun tuhkamateriaaleista on ensin poistettu vesiliukoiset komponentit pesemällä ne eri tavoin toteutetuin pesuvaihein. Kyseisiä pestyjä näytteitä verrataan tulosten tarkastelussa referenssinäytteisiin, joita ei ole pesty. Työssä tutkitut tuhkat olivat yhdyskuntajätteen polttolaitoksen pohjakuona (GD#5) ja rikinpoiston lopputuote (GD#2). Geopolymerisointi toteutetaan, koska yleisesti näissä suurissa määrin syntyvissä teollisuuden jätemateriaaleissa suurina pitoisuuksina olevat raskasmetallit ja suolat tekevät niistä ympäristölle haitallisia. Geopolymerisoimalla näitä jätemateriaaleja voitaisiin käyttää hyödyksi sekä samalla pyrittäisiin vähentämään raskasmetallien liukoisuutta ympäristöön. Työssä pyrittiin siis selvittämään, miten hyvin näytteet lujittuvat pesun, eli haitallisten vesiliukoisten komponenttien poistamisen, jälkeen. Saaduista tuloksista pystyttiin myös havaitsemaan liukenevatko geopolymeerien ehdottomat rakennusaineet pois, eli lujittuvatko näytteet ollenkaan pesuvaiheen jälkeen. Työn suoritukseen kuului kaksi päävaihetta. Ensimmäinen vaihe oli laboratoriotyöt, joka tarkoitti näytteiden valmistusvaihetta. Aluksi toteutettiin pesuvaihe pesemällä tuhkaa joko 1- tai 2-vaiheisesti eri neste/kiintoainesuhteella, jonka jälkeen suodatettiin pesuvesi pois. Pestyyn tuhkamassaan sekoitettiin käytetystä tuhkamateriaalista riippuen yhdestä kahteen eri aktivaattoria, täytettiin muotit seoksella ja annettiin näytteiden kovettua tilassa, missä oli tasainen huoneenlämpötila ja vakaa ilmankosteus. Näytteistä mitattiin puristuslujuudet 3, 7 ja 28 vuorokauden lujittumisen jälkeen. Toinen vaihe oli saatujen tulosten käsittely ja kirjallisuuskatsauksen tekeminen. Saaduista lujuustuloksista saatiin selville reseptikohtaiset puristuslujuuden arvot. Tässä kandidaatintyössä saavutetut tärkeimmät tulokset olivat GD#5:n kohdalla se, että ilman sidosainetta tuhkan havaittiin pesun jälkeen olevan erittäin haurasta ja heikkoa, eli pesty eikä edes pesemätön GD#5 yksistään soveltunut geopolymerisoinnin raaka-aineeksi. GD#2:n tulosten perusteella voitiin päätellä, että pesuprosessi ei sovellu tälle tuhkalle, koska pesun jälkeen tuhka lujittui hieman eli pesu heikensi tuhkan työstettävyyttä. Työssä tarkasteltiin myös eroja 1- ja 2-vaiheisten pesujen tuloksissa. Pääsääntöisesti 2-vaiheisen pesun lujuustulokset olivat hieman parempia 1-vaiheisiin pesuihin verrattuna. Toisaalta yksivaiheiset pesuprosessit ovat helpompia ja nopeampia toteuttaa sekä niiden kohdalla puhutaan pienemmistä vesimääristä. Poikkeuksena 2-vaiheisen pesun paremmuuteen on tuhkamateriaali GD#5:n lujuustulokset, jonka kohdalla kyseisen pesun läpikäyneet näytteet olivat lujuustuloksiltaan jonkin verran yksivaiheisia pesuja huonompia. Masuunikuonan käyttö sidosaineena paransi tuloksia huomattavasti verrattuna pelkkään tuhkamateriaalin geopolymerisoimiseen. Tämän kandidaatintyön tuloksia voidaan yleisesti hyödyntää kyseisten tuhkamateriaalien, masuunikuonan ja näiden yhdistelmien geopolymerisoinnin tutkimuksessaThe objective of this thesis was to study the possibility to use two different kind of industrial waste materials (desulphurization product GD#2 and municipal solid waste incinerator bottom ash GD#5) as a raw material in geopolymerisation. Both ash types include a lot of harmful substances such as heavy metals, sulphates and chlorides which can decrease the hardening of the geopolymer structure. The aim was to research the possibility to wash these harmful substances from the raw materials and study whether the strength properties are better or not. Both ash types were geopolymerized with and without blast furnace slag, which was used as a co-binder in these tests. The research was done in two stages. The first stage contained the washing and geopolymerisation of ash materials according to different recipes and the definition of compression strengths of the samples after the 3, 7 and 28 days curing time. The second stage was the handling of obtained results and the doing of the literature part of the work. The washing stage included either 1- or 2-step washing method with liquid-to-solid ratio of 2 or 5. Then the washed ashes were filtered and the activator (1 and/or 2) were mixed with the filtered ash (with or without blast furnace slag) according to different recipes. The cubic moulds were filled with the paste and the samples were allowed to cure in constant humidity and room temperature. The most important results achieved in this thesis were that the both ash materials need the co-binder material (blast furnace slag) to improve strength properties. According to the results the wash process is not suitable for GD#2 because the workability decreased after washing process. When comparing the strength results after 1- and 2-step washing methods, the 2-step method improved the results a bit. On the other hand, the 1-step washing processes is easier and quicker to execute and consumes lower amount of water. One exception with the results was with GD#5, which had not higher strength results after 2-step washing process. The results of this candidate work can be generally utilized in the study of the geopolymerisation of the ash materials in question, blast furnace slag and these combinations

In this monograph we continue with the inspection initiated in [1] on the fundamental tools introduced in the approach proposed in [2,3] for the study of metastability. We give the definition of the Poisson random measures and prove the main properties that we will subsequently use to construct Markov processes with finite state space. Such construction will allow us to provide a probabilistic proof of the fact that the law of a Markov process solves the martingal problem.En esta monografía continuamos con el desarrollo iniciado en [1] sobre las herramientas fundamentales usadas en el abordaje propuesto en [2,3] para el estudio de la metaestabilidad. Definimos las medidas aleatorias de Poisson y probamos las principales propiedades que seran usadas para construir procesos de Markov con espacio de estados finito. Esta forma de abordar la propiedad Markoviana nos permitirá dar una demostración probabilística de que la ley de un proceso de Markov resuelve un problema martingala.

Testo completoAbstract (sommario):
Dans cette thèse nous étudions les structures de Lie-Poisson. De manière plus précise deux thèmes sont abordés. Le premier est de nature classificatoire. Nous donnons une description complète des algèbres de Manin (c'est-à-dire les grandes algèbres d'un triple de Manin) associées à des structures de bigèbre de lie sur une algèbre de lie réelle semi-simple. Ensuite, en adaptant au cas réel les résultats de Belavin et Drinfeld décrivant les solutions de l'équation de Yang-Baxter standard modifiée non nulle sur une algèbre de lie semi-simple complexe, nous donnons les solutions générales de l'équation de Yang-Baxter modifiée standard non nulle sur une algèbre de lie réelle semi-simple. Enfin nous donnons des résultats partiels concernant les structures de bigèbre liées aux solutions de l'équation de Yang-Baxter modifiée non standard sur une algèbre de lie réelle simple telle que sa complexifiée ne soit pas simple. Le deuxième thème est celui de la linéarisation locale d'une structure de lie-poisson. Nous montrons, en utilisant le théorème de linéarisation analytique dans le cas d'une structure de poisson de j. Conn, que si (g,p) est un groupe de lie-poisson, et si l'algèbre duale est la somme directe d'un idéal semi-simple et d'un idéal abélien, alors p est analytiquement linéarisable dans un voisinage de l'identité. Dans le cadre d'une structure de poisson générale cette proposition peut-être mise en défaut. Nous montrons par ailleurs que toute structure de lie-poisson exacte sur un groupe de lie nilpotent de pas deux est linéaire, sur un groupe de lie nilpotent de pas trois et de dimension inferieure ou égale a six est linéarisable et qu'il existe des structures de lie-poisson exactes sur un groupe de lie nilpotent de pas quatre et de dimension cinq qui ne sont pas linéarisables

Testo completoAbstract (sommario):
Dans un premier chapitre, on associe a chaque structure de poisson des isomorphismes infinitesimaux d'un type special, appeles rotationnels de la structure. Utilisant ces rotationnels, on definit une strategie de classification a isomorphismes lineaires pres, des structures de poisson quadratiques. Cette strategie donne une classification complete en dimension 3, partielle en dimension 4, et permet d'obtenir generiquement les modeles des structures de poisson quadratiques en toute dimension. Dans le second chapitre, on montre la non-degenerescence formelle des structures de poisson quadratiques dont le rotationnel possede des valeurs propres ne verifiant pas certaines relations de non-resonance. Au passage, on donne generiquement une forme normale formelle des structures de poisson dont le 1-jet est nul en un point. Enfin, dans le cas de la dimension 3, on montre qu'on peut associer a toute structure de poisson quadratique a rotationnel inversible, une action commutative de r#2 sur r#3, donnee par le rotationnel et un autre champ de vecteurs. Lorsque cette action est non resonnante et hyperbolique, on montre que la structure de poisson quadratique associee est non-degeneree au sens differentiable

Testo completoAbstract (sommario):
The Bavarian composer Johann Nepomuk von Poissl was regarded by many in the second decade of the nineteenth century as German opera’s greatest hope. Though neglected by later musicology, in his day Poissl was a central figure in the aesthetic discourses surrounding opera, being prominent as a composer, librettist, translator, journalist and director of the Munich Court Theatre. He was also a profoundly ideological artist, expressing in his operas a distinctive vision of Bavarian nationhood and of the wider German identity. This thesis represents the first substantial study of Poissl’s operatic oeuvre. It is based on a detailed reading of his thirteen surviving operas, all unpublished. It uses many previously untranscribed and untranslated sources. It shows how Poissl, in his prose writings as well as his operas, addressed what he and his contemporaries saw as the fundamental aesthetic values of opera. It also shows that several of Poissl’s works were a response to specific political, ideological and cultural issues. These include the Franco-Bavarian alliance, the post-Napoleonic settlement and the Catholic restoration of Bavaria under King Ludwig I. These threads are drawn together in a case study of Poissl’s opera Athalia (1814). This considers not only the literary and musical form of this piece but also its ideological content. It shows how Poissl’s particular vision of nationhood and faith was embedded not only in Athalia’s text but also in its music. It clarifies the dialogue-based form in which the opera was originally performed. It suggests that Poissl’s later addition of recitatives to Athalia not only obscured the dramatic and musical strengths of this particular work, but also gave rise to musicological misconceptions which have distorted and restricted our view of Poissl’s oeuvre as a whole.

Testo completoAbstract (sommario):
Nowadays, many firms are or have already been engaged in an acquisition process, either as target or acquirer. While these companies seem confident in the potential returns of such endeavors, the positive aspect of those acquisitions has yet to be proven. There is indeed a vivid discussion among scholars, which are divided into two categories. On the one hand, there are those considering acquisitions as a source of additional knowledge that will in turn increase the innovation within the company; and on the other hand, those denigrating acquisitions, assimilating them to a “poison pill” for innovation. The purpose of this research is therefore to investigate whether the acquisitions will influence positively or negatively the innovative performance of companies involved in such processes. Using a quantitative approach, this research analyzed the R&D investments made by those companies and the issued patents gained in return. The research provides mixed results. While acquisitions seem to have a positive impact on the companies‟ innovative performance during the two years following the acquisition, this positive impact does not last and even becomes negative during the third year.

Resumo: O objetivo desse trabalho é estudar as equações de Hamilton no contexto estocástico. Sendo necessário para tal um pouco de conhecimento a cerca dos seguintes assuntos: cálculo estocástico, geometria de segunda ordem, estruturas simpléticas e de Poisson. Abordamos importantes resultados, dentre eles o teorema de Darboux (coordenadas locais) em variedades simpléticas, teorema de Lie-Weinstein que de certa forma generaliza o teorema de Darboux em variedades de Poisson. Veremos que apesar de o ambiente natural para se estudar sistemas hamiltonianos ser variedades simpléticas, no caso estocástico esses sistemas se adaptam bem em variedades de Poisson. Além disso, para atingir a nossa meta, estudaremos equações diferenciais estocásticas em variedades de dimensão finita usando o operador de Stratonovich
Abstract: This dissertation deals with transfering Hamilton's equations in stochastic context. This requires some knowledge about the following: stochastic calculus, second order geometry and Poisson and simplectic structures. Important results that will be discussed in this theory are Darboux's theorem (local coordinates) for simplectic manifolds, and Lie-Weintein's theorem that is in a certain way of Darboux's theorem on Poisson manifolds. We will see that although the natural environment for studying hamiltonian systems is symplectic manifolds, if we have a Poisson structure we will still be able to study them. Moreover, to achieve our goal, we will study stochastic differential equations on finite dimensional manifolds using the Stratonovich operator

Testo completoAbstract (sommario):
La mise a disposition du consommateur gabonais des produits halieutiques issus des zones de production implique un cheminement des produits a travers de nombreuses operations techniques. Les premieres etapes du marche comprennent la capture, le conditionnement et le groupage des produits de la peche. Ils se deroulent sur les lieux de production et sont suivis de l'expedition sur les marches. L'etape suivante de la distribution est constituee par la commercialisation puis la consommation de ces produits par differentes familles. Cependant la commercialisation du poisson est confrontee a plusieurs problemes. La situation actuelle se caracterise par l'insuffisance et la mauvaise qualite de l'equipement des revendeurs de poissons et de l'equipement routier, des marches souvent insalubres, des infrastructures de mises a terre et de conditionnement inadaptees voire inexistances. Il est a craindre, dans ces conditions, que les differents projets de developpement du marche des produits halieutiques ne puissent voir le jourTo put halieutic products at gabonese consumers' disposal, one should follow severals technical operations. This first steps of marketing deal with capture, conditioning and bulking of commodities. They take place in the production areas before being dispatched on marketplaces. The following stage deals with handling and consumption by different households. However handling of halieutic products encounters many problems : - shortage and bad quality of fish retailers' equipment - insufficiency and bad quality of roads - maladjusted or non-existent of landing and conditioning infrastructures. In such conditions, one should fear the non realization of fish-markets development projects

Soit (m, p) une variete de poisson de rang nul a l'origine. Si l'on considere le developpement en serie de taylor du tenseur p, on peut ecrire p=p#l+r ou p#l designe la partie lineaire de p et ou r est d'ordre superieur a 2. On dit que p est linearisable (formellement, analytiquement ou differentiablement) si p est localement diffeomorphe (au sens precise) a p#l. Si l'on note que les coefficients de p#l sont les constantes de structures d'une algebre de lie g, on dira que g est non degeneree pour exprimer que toutes les structures de poisson associees a g sont linearisables. Ce travail debute sur l'etude des algebres de lie de dimension 4 et des arguments geometriques permettent de demontrer qu'elles sont toutes degenerees sauf 4 algebres particulieres. Ceci amene dans un second chapitre a demontrer la non-degenerescence formelle de g#2x. . .

Testo completoAbstract (sommario):
To account for overdispersion in count data, that is variation in excess of that justified from the assumed model, one may consider an additional source of variation, by assuming that each observation, Yi, i = 1, ..., m, arises from a conditionally independent Poisson distribution, given its respective mean qi, i = 1, ..., m. We review various frequentist methods for the estimation of the Poisson parameters qi, i = 1, ..., m, which are based on the inadmissibility of the usual unbiased maximum likelihood estimator, in terms of the associated risk in dimensions greater than two. The so called shrinkage estimators adjust the maximum likelihood estimates towards a fixed or data-determined point, abandoning unbiasedness in favour of lower risk. Inferences for the parameters of interest can also be drawn employing Bayesian methods. Conjugate models are often adopted to facilitate the computational procedure. In this thesis we assume a nonconjugate log-normal prior distribution, which allows for more dispersion in the Poisson means and can also accommodate a correlation structure. We derive two empirical Bayes estimators, which approximate the posterior mean. The first is based on a linear shrinkage rule, while the second employs a non-iterative importance sampling technique. The frequency properties of the two estimators in terms of average risk are assessed and compared to other estimating approaches proposed in the literature. A full hierarchical Bayes analysis is also considered, assuming both informative and non-informative prior distributions at the lower stage of the hierarchy. Some analytical posterior inferences, based on simple approximations are obtained. We then employ stochastic simulation techniques, suggesting two Markov chain Monte Carlo methods which involve the Gibbs sampler and a hybrid strategy. They rely on a log-normal/gamma mixture approximation to the full conditional posterior distribution of the parameters qi, i = 1, ,..., m. The shrinkage behaviour of the hierarchical Bayes estimator is explored, and its average risk is examined through frequency simulations. Examples and applications of the considered methods are given throughout the thesis.

Testo completoAbstract (sommario):
Foodborne illnesses continue to have a negative impact on the nation's health, accounting annually for an estimated 76 million illnesses, 325,000 hospitalizations, and 5,000 deaths in the United States. Syndromic surveillance systems that analyze pre-diagnostic data, such as pharmaceutical sales data are being used to monitor diarrheal disease. The purpose of this study is to evaluate the usefulness of a poison control center (PCC) data collection and triage system for early detection of increases in foodborne illnesses.Data on calls to the Arizona Poison and Drug Information Center (APDIC) reporting suspected foodborne illnesses, and Pima County Health Department (PCHD) enteric illness reports were obtained for July 1, 2002 - June 30, 2007. Prediction algorithms were constructed using the first two and a half years, and validated in the remaining two and a half years. Multiple outcomes were assessed using unadjusted and adjusted raw counts, five and seven day moving averages, and exponentially weighted moving averages. Sensitivity analyses were conducted to evaluate model performance. Increases in PCHD laboratory reports of enteric illnesses were used as a proxy measure for foodborne disease outbreaks.Over the five year study period there were 1,094 APDIC calls reporting suspected foodborne illnesses, and 2,433 PCHD enteric illness cases. Seventy-five percent of cases were reported to PCHD within 23 days of symptom onset. In contrast, 62% of callers contacted APDIC within 24 hours of symptom onset. Forty percent of PCHD cases were missing symptom onset dates, which necessitated constructing and validating predictive algorithms using only those PCHD cases with known symptom onset dates.None of the prediction models performed at sensitivity levels considered acceptable by public health department standards. However, it is possible that a temporal relationship actually exists, but data quality (lack of outbreak dates, and missing symptom onset dates) may have prevented its detection. The study suggests that current surveillance by PCCs is insufficient as a univariate model for syndromic surveillance of diarrheal illness because of low caller volume reporting suspected foodborne illnesses; this can be improved. Methods were discussed to utilize PCCs for active surveillance of foodborne illnesses that are of public health significance.

Testo completoAbstract (sommario):
In this article, a Poisson gravity model is introduced that incorporates spatial dependence
of the explained variable without relying on restrictive distributional assumptions of the
underlying data-generating process. The model comprises a spatially filtered component
including the origin-, destination-, and origin-destination-specific variables and a spatial
residual variable that captures origin- and destination-based spatial autocorrelation. We
derive a two-stage nonlinear least-squares (NLS) estimator (2NLS) that is heteroscedasticity-
robust and, thus, controls for the problem of over- or underdispersion that often
is present in the empirical analysis of discrete data or, in the case of overdispersion, if
spatial autocorrelation is present. This estimator can be shown to have desirable properties
for different distributional assumptions, like the observed flows or (spatially) filtered component
being either Poisson or negative binomial. In our spatial autoregressive (SAR)
model specification, the resulting parameter estimates can be interpreted as the implied
total impact effects defined as the sum of direct and indirect spatial feedback effects. Monte
Carlo results indicate marginal finite sample biases in the mean and standard deviation of
the parameter estimates and convergence to the true parameter values as the sample size
increases. In addition, this article illustrates the model by analyzing patent citation flows
data across European regions. (authors' abstract)

Esta dissertação se dedica ao estudo e à revisão bibliográfica da distribuição de Poisson generalizada. Essa distribuição é uma alternativa aos modelos discretos que apresentam sobredispersão. A flexibilização do valor da variância em relação ao da média é devido ao acréscimo de um parâmetro à distribuição de Poisson. A distribuição de Poisson generalizada foi inicialmente introduzida como elemento da classe de distribuições Lagrangeanas. Neste trabalho é proposta uma parametrização em função da W de Lambert que permite relacioná-la à classe de distribuições de série de potência e, desse modo, valer-se das propriedades e das características dessa classe de distribuições. Além disso, serão apresentadas aplicações de diferentes áreas do conhecimento, métodos de estimação pontual e intervalar, testes de hipóteses e as funções do software R dedicadas a essa distribuição.
In this dissertation we present a review of the generalized Poisson distribution. This distribution is an alternative to allow over dispersion in discrete models. The flexibility of the value of the variance in relation to the average is due to the presence of an additional parameter with respect to the Poisson distribution. The generalized Poisson distribution was first introduced as an element of the class of Lagrangian distributions. In this work it is proposed a new parametrization in terms of the Lambert W function that allows us to relate it to the class of power series distributions and, therefore, to use well known properties and characteristics of this class. In addition, we will present applications from different areas of knowledge, inference methods for both point and interval estimation and hypotheses testing. Were also review some R packages which deal with this distribution.

É considerado o problema de encontrar descrições de Poisson (formulações Hamiltonianas generalizadas) associadas a modelos físicos. Aspectos básicos e aplicações dos sistemas de Poisson são explanados utilizando a linguagem da geometria diferencial. Sobre geometria diferencial, consta um capítulo com noções fundamentais. São consideradas as Mecânicas de Nambu e Birkho:ff e suas relações com a Mecânica Hamiltoniana generalizada. A questão da estábilidade é discutida do ponto de vista das formulações de Poisson. Os métodos existentes atualmente para derivação de estruturas Hamiltonianas generalizadas são expostos. Em particular, o processo de redução é estudado. Propõe-se uma abordagem dedutiva e inédita para construção de formulações de Poisson. O novo método é capaz de resolver (localmente) a questão de como encontrar descrições Hamiltonianas de sistemas dinâmicos com no máximo três dimensões. Nos casos tridimensionais nos quais é conhecida uma superfície à qual as trajetórias são sempre tangentes, a nova estratégia reduz esta questão à solução de uma equação diferencial parcial de primeira ordem linear. Deste modo demonstra-se a existência (local) genérica de estruturas de Poisson para sistemas tridimensionais. O caso tridimensional é analizado com detalhe, par ticularmente no concernente à invari ância conforme da identid ade de Jacobi nesta dimensionalidade. A abordagem tratada nesta dissertação é aplicada a vários sistemas tridimensionais de interesse.The problem of finding Poisson descriptions (generalized Hamiltonian formulations) assoei ateei with physical models is considered. The basic features anel aplications of Poisson systems are explained in the language of differential geometry. One chapter is included with the fundamental notions on differential geometry. The Nambu anel Birkhoff's Mechanics anel their relationship with the generalized Hamiltonian Mechanics are considered. The question of stability is discussed from the point of view of the Poisson formulations. The currently existing methods for derivation of generalized Hamiltonian structures are reviewed. Particularly, the reduction process is analized. A deductive approach is proposed for the construction of Poisson formu lations. The new method can solve (locally) the question of how to finei Hamiltonian descriptions of dynamical systems in, at most, three dimensions. When a surface to wich the motion is always tangent is known , in three dimensions the new approach reduces the problem to the solution of a linear partia! differential equation of first order. This demonstrates the general existence (local) of Poisson structures for tridimensional systems. The tridimensional case is analized in detail, particularly in what concerns the conformai invariance of the Jacobi identity in this dimensionality. The approach proposed in this dissertation is applied to various tridimensional systems of interest.
