A crise global do capitalismo eclodida no ano de 2008 evidenciou o risco sistêmico a que a atividade econômica ficou exposta a partir da sua desregulamentação, implementada, a partir dos anos 1980, pelo chamado neoliberalismo, e do desenvolvimento dos meios de comunicação e informáticos, que a interligou em nível planetário. Seus efeitos devastadores somente puderam ser contidos por meio de intervenção estatal, com a injeção de muito dinheiro público na atividade econômica privada, o que trouxe à tona a discussão quanto ao real papel regulatório do Estado sobre a economia nesse contexto. No panorama atual do desenvolvimento da sociedade capitalista e contemporânea, há, muitas vezes, verdadeiro divórcio entre os interesses do real proprietário da empresa (ausente ou passivo) e o corpo de gestores contratados da companhia, impondo a necessidade de maior confiabilidade e transparência na apuração e nos demonstrativos dos resultados empresariais. Surge daí o conceito de boas práticas de governança corporativa, do qual um dos pilares de sustentação é o denominado compliance, que funciona como uma estrutura verificadora e validadora do bom funcionamento, da correção e da confiabilidade da administração, prevenindo riscos imanentes à atividade empresarial. Surge, nesse cenário, uma concepção de autorregulação regulada ou forçada da atividade econômica, pela qual o Estado supera uma postura meramente repressora de desvios encontrados, que relegava ao particular sua própria organização, passando a impor uma pauta mínima de obrigações organizacionais, que necessita ser cumprida e implementada para prevenir riscos de condutas antiéticas ou mesmo criminosas. O papel do direito penal, sempre mais modesto do que dele se espera, acaba ganhando muita importância por atuar como norma de reforço à tutela de deveres organizacionais e de autofiscalização da atividade econômica. Os meios eleitos para atingir esses objetivos são a utilização de tipos penais de perigo abstrato, omissivos ou comissivos por omissão; a incriminação da corrupção privada; a promulgação de leis extraterritoriais que preveem a colaboração entre Estados no combate à criminalidade; a adoção de sistemas legais autodenominados administrativos, mas que são penais em sua essência; a crescente aceitação e utilização da responsabilidade penal da pessoa jurídica. Partindo de constatações criminológicas e proposições político-criminais, a presente tese visa a propor a criação de um sistema de imputação penal das pessoas jurídicas baseado na ideia de fato próprio culpável, com a culpabilidade atrelada ao conceito de defeito de organização, visando a superar o déficit na aplicação do modelo adotado pela Lei nº 9.605/1998, na qual não há o estabelecimento de quaisquer critérios para delimitar o âmbito das ações corporativas culpáveis. Para tanto, buscaram-se, em modelos jurídicos alienígenas (italiano, chileno e espanhol), experiências e exemplos que pudessem auxiliar na proposição de critérios reitores de um novo modelo adaptado à realidade brasileira, pelos quais se almeja a maximização das possibilidades de aplicação do instituto, de um lado, e a maior amplitude possível das garantias penais, de outro. / The global crisis of capitalism, which emerged in 2008, displayed the systemic risk that economic activity was exposed to. This risk occurs due to the deregulation implemented from 1980 by the so-called neoliberalism as well as due to the development of both the media and IT which have globally interconnected economic activity. The devastating effects of neoliberalism could only be restrained through state intervention, with the injection of great amounts of public money into private economic activity. In this context, this practice brought up the discussion on the actual regulatory role of the state in economy. In the current scenario of the development of contemporary capitalist society, there is often an actual separation between the interests of the real owner of the company (who is absent or passive) and the board of hired managers of the company. This fact generates the need for increased reliability and transparency in the calculation and statements of business results. The concept of good corporate governance practices is thus generated, which has compliance as one of its supporting pillars. Compliance works as a testing and validating structure of managerial functioning, correctness and reliability, thus, preventing risks that are inherent to business activity. In this scenario, the concept of regulated or forced self-regulation of economic activity was created. By this concept, the state goes beyond the previous position of merely repressing identified deviations, which meant that the organization could regulate itself. Now the state imposes an agenda of organizational duties, which need to be fulfilled and implemented to prevent risks of unethical or even criminal behavior. The role of criminal law, which has had a more modest scope than expected, ends up gaining importance because it acts as reinforcement rule for the protection of organizational duties and self-inspection of economic activity. The means chosen to achieve these goals are the use of criminal types of abstract danger, which may be either omissive or comissive by omission; incrimination of private corruption; enactment of extraterritorial laws that provide for collaboration among States in combating crime; adoption of legal systems in the administrative scope that are criminal in their essence; the increased acceptance and use of the criminal liability of legal entities. Starting from criminological findings and political-criminal propositions, this thesis aims at proposing the creation of a criminal imputation system of legal entities, based on the idea of a fact itself that can be considered as liable. The guilt is attached to the concept of organization defect in order to overcome the deficit in the implementation of the model adopted by Law No. 9.605/1998, which has not established any criteria to specify the scope of corporate actions that may be considered as liable to penalty for law offence. Therefore, we researched experiences and examples in foreign legal models (Italian, Chilean and Spanish legal models) that could help to propose criteria that lead to a new model adapted to the Brazilian reality, in which we aim, on the one hand, to maximize the possibilities of this new legal model, and, on the other hand, reach penal guarantees as widely as possible.

La tolérance et la gestion des fautes dans les grilles de données/calcul est d’une importance capitale. En effet, comme dans tout autre système distribué, les composants d’une grille sont susceptibles de tomber en panne à tout moment. Mais le risque de panne croît avec la taille du système, et est donc plus exacerbé dans un système de grille. En plus, tout en essayant de mettre à profit les ressources offertes par la grille, les applications tournant sur celle-ci sont de plus en plus complexes (ex. impliquent des interactions complexes, prennent des jours d’exécution), ce qui les rend plus vulnérables aux fautes. Le plus difficile dans la gestion des fautes dans une grille, c’est qu’il est difficile de savoir si une faute qui survient sur une entité de la grille est induite malicieusement ou accidentellement. Dans notre travail de thèse, nous utilisons le terme faute, au sens large, pour faire référence à tout étant inattendu qui survient sur tout composant de la grille. Certains de ces états provoquent des comportements aussi inattendus et perceptibles au niveau de la grille tandis que d’autres passent inaperçues. De plus, certaines de ces fautes sont le résultat d’une action malveillante alors que d’autres surviennent accidentellement ou instantanément. Dans ce travail de thèse, nous avons traité le cas de ces fautes induites malicieusement, et qui généralement passent inaperçues. Nous avons considéré en particulier le problème de la confidentialité et de l’intégrité des données stockées à long-terme sur la grille. L’étude de la confidentialité des données a été faite en deux temps dont la première partie concerne la confidentialité des données actives. Dans cette partie, nous avons considéré une application liée à la recherche des similitudes d’une séquence d’ADN dans une base de données contenant des séquences d’ADN et stockée sur la grille. Pour cela, nous avons proposé une méthode qui permet d’effectuer la comparaison sur un composant distant, mais tout en gardant confidentielle la séquence qui fait l’objet de la comparaison. Concernant les données passives, nous avons proposé une méthode de partage des données confidentielles et chiffrés sur la grille. En rapport avec l’intégrité des données, nous avons considéré le cas des données anonymes dans le cadre de l’intégrité des données passives. Pour les données actives, nous avons considéré le problème de la corruption des jobs exécutés sur la grille. Pour chacune des cas, nous avons proposé des mécanismes permettant de vérifier l’authenticité des données utilisées ou produites par ces applications.

According to the Constitution of South Africa, the government is required to make all the infor-mation in the ten indigenous languages of South Africa (excluding English), available to the public. For this reason, the government made the information, that already existed for these ten languages, available to the public and an effort is also been made to increase the amount of resources available in these languages (Groenewald & Du Plooy, 2010). This release of infor-mation further helps to implement Krauwer‟s (2003) idea that there is an inventory for the mini-mal number of language-related resources required for a language to be competitive at the level of research and teaching. This inventory is known as the "Basic Language Resource Kit" (BLARK). Since most of the languages in South Africa are resource scarce, it is of the best in-terest for the cultural growth of the country, that each of the indigenous South African languages develops their own BLARK. In Chapter 1, the need for the development of an implementable named entity recogniser (NER) for Afrikaans is discussed by first referring to the Constitution of South Africa’s (Republic of South Africa, 2003) language policy. Secondly, the guidelines of BLARK (Krauwer, 2003) are discussed, which is followed by a discussion of an audit that focuses on the number of re-sources and the distribution of human language technology for all eleven South African languages (Sharma Grover, Van Huyssteen & Pretorius, 2010). In respect of an audit conducted by Sharma Grover et al. (2010), it was established that there is a shortage of text-based tools for Afrikaans. This study focuses on this need for text-based tools, by focusing on the develop-ment of a NER for Afrikaans. In Chapter 2 a description is given on what an entity and a named entity is. Later in the chapter the process of technology recycling is explained, by referring to other studies where the idea of technology recycling has been applied successfully (Rayner et al., 1997). Lastly, an analysis is done on the differences that may occur between Afrikaans and Dutch named entities. These differences are divided into three categories, namely: identical cognates, non-identical cognates and unrelated entities. Chapter 3 begins with a description of Frog (van den Bosch et al, 2007), the Dutch NER used in this study, and the functions and operation of its NER-component. This is followed by a description of the Afrikaans-to-Dutch-converter (A2DC) (Van Huyssteen & Pilon, 2009) and finally the various experiments that were completed, are explained. The study consists of six experiments, the first of which was to determine the results of Frog on Dutch data. The second experiment evaluated the effectiveness of Frog on unchanged (raw) Afrikaans data. The following two experiments evaluated the results of Frog on “Dutched” Afrikaans data. The last two experiments evaluated the effectiveness of Frog on raw and “Dutched” Afrikaans data with the addition of gazetteers as part of the pre-processing step. In conclusion, a summary is given with regards to the comparisons between the NER for Afri-kaans that was developed in this study, and the NER-component that Puttkammer (2006) used in his tokeniser. Finally a few suggestions for future research are proposed. / MA (Applied Language and Literary Studies), North-West University, Vaal Triangle Campus, 2013

Les personnes publiques ont la faculté de produire des normes par voie unilatérale ou contractuelle. Toutefois, ni la jurisprudence ni les textes n'affirment l'existence d'une liberté de choix entre ces deux instruments. L'observation du droit montre davantage de situations dans les personnes publiques ne peuvent pas librement choisir que des situations dans lesquelles elles ont effectivement cette liberté de choix. Le Conseil d'État est particulièrement actif, imposant tantôt le contrat, tantôt l'acte unilatéral pour l'exercice des compétences. Aussi, dans une discipline telle que le droit administratif, où l'action des personnes publiques est strictement encadrée par les normes de compétence, la doctrine n'est en général pas favorable à la reconnaissance de véritable liberté dans l'action au profit de l'Administration. Pourtant, le caractère objectif du droit administratif n'obère pas totalement la qualité de sujet de droit des personnes publiques ni leur capacité à exprimer une volonté propre. Le principe de la liberté de choix des modes de gestion illustre par exemple cette dimension libérale de l'action administrative. En réalité, dès l'instant où les normes de compétence n'ont pas vocation à prescrire l'instrument au moyen duquel une compétence doit être exercée, les personnes publiques disposent d'une liberté de choix entre le contrat et l'acte unilatéral. Si le législateur ou le Conseil d'État imposent aux personnes publiques d'utiliser le contrat ou l'acte unilatéral pour l'exercice de telle ou telle compétence, cela ne signifie pas pour autant que, en amont, les personnes publiques n'ont pas une liberté de choix. Au contraire, l'existence de limitation à la faculté d'agir révèle l'existence d'une liberté. Dès lors, la liberté de choix entre le contrat et l'acte unilatéral et son encadrement par le droit objectif constituent les deux pièces d'une même médaille, formant ainsi un droit général du recours au contrat ou à l'acte unilatéral. Il s'est agi de tracer les contours précis, tant sur un plan conceptuel que pratique, de la liberté de choix et de l'encadrement de cette liberté de choix, en révélant les mécanismes et critères en action sur les deux versants de deux droits. / Public entities have the ability to produce standards unilaterally or under contract. However, neither the law nor the texts affirm the existence of a choice between the two instruments. Observing the right shows more situations in public entities can not freely choose that situations where they actually have this freedom of choice. The State Council is particularly active, sometimes imposing the contract, sometimes unilateral act for the exercise of powers. Also, in a discipline such as administrative law, where the action of public persons is strictly governed by the standards of jurisdiction, the doctrine is generally not favorable to the recognition of true freedom in action for the benefit of 'Administration. Yet, the objective character of administrative law does not totally hampers the quality of legal subject of public figures or their ability to express their own will. The principle of freedom of choice of management methods illustrious example this liberal dimension of administrative action. In fact, as soon as the standards of competence are not intended to prescribe the instrument by which a jurisdiction must be exercised, public figures have a choice between the contract and the unilateral act. If Parliament or the Council of State to require public entities to use the contract or unilateral act for the performance of a particular jurisdiction, this does not mean that upstream, public figures have not a freedom of choice. On the contrary, the existence of limitations on the ability to act reveals the existence of freedom. Therefore, the choice between the contract and the unilateral act and its frame by objective law are the two parts of the same coin, thus forming a general right of appeal to the contract or the unilateral act. It came to trace the precise contours, both conceptually and practically, freedom of choice and the framing of this freedom of choice by revealing the mechanisms and criteria for action on both sides of two rights

This article provides an analysis of the economic incentives and financial reporting for Special Purpose Entities (SPEs) over the last four decades. The analysis explains economic factors motivating business use of SPEs and the origins of SPEs in lease accounting and securitization transactions. Related financial reporting standards are identified and discussed, including the historical shift from a traditional control viewpoint to a primary beneficiary viewpoint for financial reporting for consolidation for SPEs (recently renamed Variable Interest Entities (VIEs) in U.S. Financial Accounting Interpretation 46R). The article also includes illustrative journal entries explaining SPE transactions from both the viewpoint of the creating company(s) and the SPE. Actual financial reporting examples and/or journal entries for SPEs created by Bank of America, General Motors Acceptance Corporation, Lucent Technologies and Alza Pharmaceuticals Corporation are also provided.

Por meio dessas mídias, os usuários trocam informações que geram usando diversos mecanismos de comunicação. Nesse contexto, mais e mais usuários transmitem e confiam em informações publicadas por outros usuários sobre uma grande variedade de tópicos, incluindo opiniões e informações sobre produtos. A extração e o processamento automáticos de informações geradas pelo usuário nas mídias sociais podem fornecer informações e conhecimento relevantes para uma variedade de aplicativos interessantes. Em particular, uma das técnicas de análise de conteúdo mais aplicadas às mídias sociais é a de mineração de opinião. Uma das tarefas básicas associadas à mineração de opinião é extrair e categorizar as entidades de destino, ou seja, identificar as menções de entidade no texto e vincular essas menções de entidade a entidades do mundo real sobre as quais as opiniões são feitas. Em nosso trabalho, nos concentramos em entidades-alvo de um tipo específico e atualmente relevante: produtos eletrônicos de consumo. Tais produtos são o principal assunto de opiniões postadas pelos usuários em várias postagens em fóruns de discussão e sites de varejo na Web. Neste trabalho, estamos interessados ​​em usar o conteúdo textual não estruturado gerado por usuários de mídia social para permitir continuamente enriquecer o conhecimento sobre produtos representados em catálogos de produtos. Portanto, a tarefa que abordamos aqui é como reconhecer e vincular menções a produtos em conteúdo textual gerado pelo usuário para o produto, de um catálogo, ao qual eles se referem. Afirmamos que duas sub-tarefas básicas surgem: primeiro, a extração de entidades alvo mencionada em conteúdo textual não-estruturado; segundo, a desambiguação de entidades extraídas, isto é, ligação menções extraídas à sua contraparte do mundo real. Neste trabalho, desenvolvemos métodos para abordar essas duas subtarefas. Esta tese detalha essas tarefas, discute nossas ideias para os métodos que desenvolvemos e apresenta nossas contribuições e resultados para esse objetivo. / Online social media has grown into an essential part of our daily life. Through these media, users exchange information that they generate by using many different communication mechanisms. In this context, more and more users pass on and trust information published by other users on a large variety of topics, including opinion and information about products. Automatically extracting and processing user-generated information in social media can provide relevant information and knowledge to a variety of interesting applications. In particular, one of the content analysis techniques most often applied to social media is that of opinion mining. One of the basic tasks associated with opinion mining is extracting and categorizing target entities, i.e., identifying entity mentions in text, and linking these entity mentions to unique real world entities about which the opinions are made. In our work, we focus on target entities of a specific, and currently relevant, type: consumer electronic products. Such products are the main subject of opinions posted by users on a number of posts in discussion forums and retail sites over the Web. In this work, we are interested in using the unstructured textual content generated by social media users to continuously allow enriching the knowledge about products represented in product catalogs. Therefore, the task we address here is how to recognize and link mentions to products in user generated textual content to the product, from a catalog, they refer to. We claim that two basic sub-tasks arise: first, extraction of target entities mentions from unstructured textual content; second, disambiguation of extracted entities, i.e., linking extracted mentions to their real world counterpart. In this work, we developed methods to address these two sub-tasks. This thesis details these tasks, discusses our ideas for the methods we developed, and presents our contributions and results towards this goal. / Não tive dificuldades, tudo funcionou corretamente.
