Memoria (licenciado en ciencias jurídicas y sociales) / El trabajo que a continuación se desarrollará se propone describir el fenómeno de la incorporación del concepto de "White Collar Crime", introducido por Edwin Sutherland en la doctrina estadounidense de la época y que más tarde se expandiría al resto del mundo. Junto con ello se pretende revisar sus problemáticas actuales y relación con la doctrina más tradicional, para posteriormente centrar la atención en una especie de delito en particular: el de colusión de precios y especialmente la figura penal chilena. En este punto se pretende revisar la vigencia de los principales puntos de la doctrina del Delito de Cuello Blanco en las características singulares de este tipo penal. Para ello, junto con analizar la conducta descrita por la legislación nacional sobre el delito de colusión de precios, se revisarán casos de relevancia nacional relacionados con este, buscando características comunes entre ellos y contrastándola con los postulados de la doctrina del Delito de Cuello Blanco.

This thesis deals with a conformal field theoretical treatment of abelian anyons in (1 + 1)-dimensions and their relation to the integrable Calogero-Sutherland models. We generalize previous work relating anyons to the Calogero-Sutherland model by showing that the correlation function of the anyon field operators corresponds to the eigenfunctions of the deformed Calogero-Sutherland model. Our results suggest a physical application of the deformed Calogero-Sutherland model in the context of the fractional quantum Hall effect (FQHE). A key aspect for this work is the introduction of the dual anyon field operators, which obey a natural generalization of the canonical anti-commutation relation.

Tableau d’honneur de la Faculté des études supérieures et postdoctorales, 2008-2009 / Les polynômes de Jack sont des polynômes symétriques qui constituent les fonctions propres de l'hamiltonien du problème à N corps complètement intégrable de Calogero- Moser-Sutherland (CMS). Ces polynômes sont bien connus en physique et en mathématiques et plusieurs de leurs propriétés ont été obtenues. Entre autres, il existe des règles, nommées formules de Pieri, qui permettent de développer un produit de deux polynômes de Jack dans une combinaison linéaire de polynômes de Jack. Ces formules ont mené à l'obtention d'opérateurs différentiels analogues à des opérateurs de création qui permettent de générer ces polynômes sans avoir à diagonaliser explicitement l'hamiltonien. Dans le cadre de ce mémoire, on s'intéresse au modèle CMS supersymétrique et plus particulièrement aux généralisations des formules de Pieri. On introduit aussi quelques propriétés des superpolynômes de Jack qui seront utiles pour prouver les formules de Pieri obtenues dans le cas supersymétrique.

An exact quantum Monte Carlo algorithm for interacting particles in the spatial continuum is extended to exploit the massive parallelism offered by graphics processing units. Its efficacy is tested on the Calogero-Sutherland model describing a system of bosons interacting in one spatial dimension via an inverse square law. Due to the long range nature of the interactions, this model has proved difficult to simulate via conventional path integral Monte Carlo methods running on conventional processors. Using Graphics Processing Units, optimal speedup factors of up to 640 times are obtained for N = 126 particles. The known results for the ground state energy are confirmed and, for the first time, the effects of thermal fluctuations at finite temperature are explored.

Na primeira estudamos uma classe de ensembles de movimento browniano (EMB) da teoria de matrizes aleatórias, gerados a partir da teoria matricial de processos estocásticos markovianos. Os ensembles são caracterizados por uma equação de Fokker-Planck e estão intimamente relacionados a hamiltonianos de sistemas quânticos do tipo Calogero-Sutherland. Esta conexão leva a um esquema geral de classificação baseada numa recente generalização multidimensional dos polinômios ortogonais clássicos. Mostramos que, sob certas condições, os EMB englobam os ensembles de matrizes de transferência. Desta forma, desenvolvemos um tratamento unificado dos ensembles de polinômios e de matrizes de transferência que, além de servir como um esquema de classificação das diversas classes de simetria, fornece técnicas eficientes de cálculo. Desenvolvemos métodos de Fokker-Planck para o cálculo de médias de observáveis representados por estatísticas lineares, assim como para o cálculo de funções de correlação. Neste contexto, desenvolvemos um método de transformada integral e uma generalização do método das funções biortogonais para o cálculo da função de correlação de n-pontos. Os resultados deduzidos neste contexto geral são aplicados a pontos e fios quânticos. Em particular, apresentamos um estudo numérico de propriedades de transporte em pontos quânticos com simetria quiral. Na segunda parte, estudamos uma cavidade caótica balística acoplada, via barreiras de transparência arbitrária, a dois guias semi-infinitos usando as duas abordagens de teoria de circuito disponíveis na literatura: a escalar e a matricial. Mostramos a equivalência destas teorias através do cálculo dos cumulantes da estatística de contagem. Para isso, determinamos as funções geratrizes fornecidas pelas duas teorias e verificamos a concordância dos 18 primeiros cumulantes usando um programa de computação algébrica. Também estudamos distribuições exatas de corrente de alguns sistemas simples de dois terminais, como um ponto quântico com barreiras simétricas. Estes resultados são importantes, pois fornecem uma grandeza diretamente mensurável em experimentos

no / This paper analyses the verbal and textual hostility employed by rioters, politicians and the media in Sydney (Australia) in December 2005 in the battle over Sutherland Shire¿s Cronulla Beach. By better understanding the linguistic conventions underlying all forms of maledictive hate, we are better able to address the false antimonies between free speech and the regulation of speech. It is also argued that understanding the harms of hate speech provides us with the tools necessary to create a more responsive framework for criminalising some forms of hate speech as a preliminary process in reducing or eliminating hate violence.

This study examines a largely unexplored aspect of Sutherland’s (1974) model of differential association: the interplay of general and crime specific definitions favorable towards crime. Do individuals learn the specific techniques of a type of crime through interactions or do social interactions produce a general disposition towards all types of criminal behavior? Little prior research has been done on the influence of these definitions. Instead studies focus on only one or another, which leaves the details of general/specific definitions unexplored. With the aid of a mixed methodology of statistical and network analysis, this study explores general/specific definitions simultaneously by focusing on relationships between egos and alters. If alters commit similar crimes, it is likely that crime specific definitions are being learned; if crimes are dissimilar then general definitions are more likely. Using police data on a known criminal network located in an urban capital, I test the relationship between the criminal behaviors of egos and alters. The study also compares the centrality of the node to the commonality of crime they commit. This provides an understanding of how key nodes in the network affect the dissemination of criminal definitions. Overall, while variations exist for criminal types, the study finds that crime specific definitions dominate the network and, therefore, have greater influence over respondents’ criminal behavior. Conversely, I found no clear pattern which indicates that high centrality nodes commit more common crimes. This may indicate that high centrality nodes are responsible for disseminating general definitions of crime while most nodes communicate crime specific definition.

This Doctoral thesis gives an introduction to the concept of kernel functionsand their signicance in the theory of special functions. Of particularinterest is the use of kernel function methods for constructing exact solutionsof Schrodinger type equations, in one spatial dimension, with interactions governedby elliptic functions. The method is applicable to a large class of exactlysolvable systems of Calogero-Moser-Sutherland type, as well as integrable generalizationsthereof. It is known that the Schrodinger operators with ellipticpotentials have special limiting cases with exact eigenfunctions given by orthogonalpolynomials. These special cases are discussed in greater detail inorder to explain the kernel function methods with particular focus on the Jacobipolynomials and Jack polynomials. / <p>QC 20161003</p>
