Conselho Nacional de Desenvolvimento Científico e Tecnológico / There is a deficit in the housing sector in Brazil that affects both urban and rural area in the country. To reverse this unfavorable scenario, the federal government created in 2009 the Rural Housing Program (PNHR) that is part of a social policy that promotes access to housing to applicants for housing in rural areas and socioeconomic vulnerability condition. The rural housing deficit in the run-up to implementation of PNHR in 2008 was 916,478 housing units, after five years of operation of the Program, in 2014, 122,013 housing units were built in Brazil. This paper presents a study of the implementation of the Rural Housing Program in Cachoeira do Sul / RS, describing the historical aspects of housing in Brazil, the role of social actors in the construction of this policy, as well as major advances, barriers and results obtained from the advent of PNHR in the city. / Há um déficit no setor habitacional no Brasil que atinge tanto a zona urbana como a zona rural no país. Para reverter este cenário desfavorável, o governo federal criou em 2009 o Programa de Habitação Rural (PNHR) que faz parte de uma política social que propicia o acesso à moradia aos demandantes por habitação da zona rural e em condição de vulnerabilidade socioeconômica. O déficit habitacional rural no que antecedeu a implementação do PNHR, em 2008, era de 916.478 unidades habitacionais, passados cincos anos da operacionalização do Programa, em 2014, 122.013 unidades habitacionais foram construídas no Brasil. Este trabalho apresenta um estudo da operacionalização do Programa de Habitação Rural em Cachoeira do Sul/RS, descrevendo os aspectos históricos da habitação no Brasil, a atuação dos atores sociais na construção desta política, bem como, os principais avanços, entraves e resultados obtidos com o advento do PNHR no município.

Atualmente, é comum que usuários levem em consideração a localização geográfica dos documentos, é dizer considerar o escopo geográfico que está sendo tratado no contexto do documento, nos processos de Recuperação de Informação. No entanto, os sistemas convencionais de extração de informação que estão baseados em palavras-chave não consideram que as palavras podem representar entidades geográficas espacialmente relacionadas com outras entidades nos documentos. Para resolver esse problema, é necessário viabilizar o georreferenciamento dos textos, ou seja, identificar as entidades geográficas presentes e associá-las com sua correta localização espacial. A identificação e desambiguação das entidades geográficas apresenta desafios importantes, principalmente do ponto de vista linguístico, já que um topônimo, pode possuir variados tipos de ambiguidade associados. Esse problema de ambiguidade causa ruido nos processos de recuperação de informação, já que o mesmo termo pode ter informação relevante ou irrelevante associada. Assim, a principal estratégia para superar os problemas de ambiguidade, compreende a identificação de evidências que auxiliem na identificação e desambiguação das localidades nos textos. O presente trabalho propõe uma metodologia que permite identificar e determinar a cobertura espacial dos documentos, denominada SpatialCIM. A metodologia SpatialCIM tem o objetivo de organizar os processos de resolução de topônimos. Assim, o principal objetivo deste trabalho é avaliar e selecionar técnicas de desambiguação que permitam resolver a ambiguidade dos topônimos nos textos. Para isso, foram propostas e desenvolvidas as abordagens de (1)Desambiguação por Pontos e a (2)Desambiguação Textual e Estrutural. Essas abordagens, exploram duas técnicas diferentes de desambiguação de topônimos, as quais, geram e desambiguam os caminhos geográficos associados aos topônimos reconhecidos para cada documento. Assim, a hipótese desta pesquisa é que o uso das técnicas de desambiguação de topônimos viabilizam uma melhor localização espacial dos documentos. A partir dos resultados obtidos neste trabalho, foi possível demonstrar que as técnicas de desambiguação melhoram a precisão e revocação na classificação espacial dos documentos. Demonstrou-se também o impacto positivo do uso de uma ferramenta linguística no processo de reconhecimento das entidades geográficas. Assim, foi demostrada a utilidade dos processos de desambiguação para a obtenção da cobertura espacial dos documentos / Currently, it is usual that users take into account the geographical localization of the documents in the Information Retrieval process. However, the conventional information retrieval systems based on key-word matching do not consider which words can represent geographical entities that are spatially related to other entities in the documents. To solve this problem, it is necessary to enable the geo-referencing of texts by identifying the geographical entities present in text and associate them with their correct spatial location. The identification and disambiguation of the geographical entities present major challenges mainly from the linguistic point of view, since one location can have different types of associated ambiguity. The ambiguity problem causes noise in the process of information retrieval, since the same term may have relevant or irrelevant information associated. Thus, the main strategy to overcome these problems, include the identification of evidence to assist in the identification and disambiguation of locations in the texts. This study proposes a methodology that allows the identification and spatial localization of the documents, denominated SpatialCIM. The SpatialCIM methodology has the objective to organize the Topônym Resolution process. Therefore the main objective of this study is to evaluate and select disambiguation techniques that allow solving the toponym ambiguity in texts. Therefore, we proposed and developed the approaches of (1) Disambiguation for Points and (2) Textual and Structural Disambiguation. These approaches exploit two different techniques of toponym disambiguation, which generate and desambiguate the associated paths with the recognized geographical toponym for each document. Therefore the hypothesis is, that the use of the toponyms disambiguation techniques enable a better spatial localization of documents. From the results it was possible to demonstrate that the disambiguation techniques improve the precision and recall for the spatial classification of documents. The positive effect of using a linguistic tool for the process of geographical entities recognition was also demonstrated. Thus, it was proved the usefulness of the disambiguation process for obtaining a spatial coverage of the document

Uma etapa crucial desse processo é a Resolução de Entidades, que consiste em identificar instâncias que se referem à mesma entidade do mundo real. A Resolução de Entidades se subdivide em várias fases, incluindo uma fase de comparação entre pares de instâncias. Nesta fase, são utilizadas funções que avaliam a similaridade entre os valores dos atributos que descrevem as instâncias. É importante notar que a qualidade do resultado do processo de Resolução de Entidades é diretamente afetada pelo conjunto de atributos selecionados para a fase de comparação de instâncias. Contudo, selecionar tais atributos pode ser um grande desafio, devido ao grande número de atributos que descrevem as instâncias ou à baixa relevância de alguns atributos para o processo de Resolução de Entidades. Na literatura existem alguns trabalhos que abordam esse problema. Em sua maioria, as abordagens propostas para seleção de atributos utilizam aprendizagem de máquina. No entanto, além da necessidade de um conjunto de treinamento, cuja definição é uma tarefa difícil, principalmente em cenários de grandes volumes de dados, a aprendizagem de máquina é um processo custoso. Neste contexto, este trabalho propõe uma estratégia para seleção de atributos relevantes a serem considerados na fase de comparação de instâncias do processo de Resolução de Entidades. A estratégia proposta considera critérios relacionados aos dados, tais como a densidade e repetição de valores de cada atributo, e critérios relacionados às fontes, tal como a confiabilidade, para avaliar a relevância de um atributo para a fase de comparação de instâncias. Um atributo é considerado relevante se contribui positivamente para a identificação de correspondências verdadeiras, e irrelevante se contribui na identificação de correspondências erradas (falsos positivos e falsos negativos). Em experimentos realizados, utilizando a estratégia proposta, foi possível alcançar bons resultados na comparação de instâncias do processo de Resolução de Entidades, ou seja, os atributos dados como relevantes foram aqueles que contribuíram para encontrar o maior número de correspondências verdadeiras, com o menor número de correspondências erradas. / Data integration is an essential task for achieving a unified view of data stored in autonomous, heterogeneous and distributed sources. A key step in this process is Entity Resolution, which consists of identifying instances that refer to the same real-world entity. Entity Resolution can be subdivided into several stages, including a comparison step between instance pairs. In this step, functions that check the similarity between values of attributes are used to discover equivalent instances. It is important to note that the quality of the result of the entity resolution process is directly affected by the set of selected attributes used to compare the instances. However, selecting such attributes can be challenging, due to either the large number of attributes that describes an instance or to the low relevance of some attributes regarding to the entity resolution process. In the literature, there are some approaches that investigated this problem. Most of them employ machine learning techniques for selecting relevant attributes. Usually, these techniques are computationally costly and also have the necessity of defining a training set, which requirements are non-trivial, mainly in large volumes of data scenarios. In this context, this work proposes a strategy for selecting relevant attributes to be considered in the instance comparison phase of the process of Entity Resolution. The proposed strategy considers criteria related to data, such as density and repetition of values of each attribute, and related to sources, such as reliability, to evaluate the relevance of the attributes. An attribute is considered relevant if contributes positively for the identification of true matches, and irrelevant if contributes for the identification of incorrect matches (false positives and false negatives). In our experiments, the proposed strategy achieved good results for the Entity Resolution process. That is, the attributes classified as relevant were the ones that contributed to find the greatest number of true matches with a few incorrect matches.

A teoria da desconsideração da personalidade jurídica se consolidou em nosso ordenamento jurídico em razão de sua importância para combater o abuso da pessoa jurídica e fraudes que pudessem ser cometidas sob o manto da personalidade jurídica e a autonomia patrimonial das Empresas. Nesse aspecto, importante explicitar como os diversos tipos de sociedades previstos em nosso ordenamento se relacionam com a responsabilidade de sócios e administradores, razão principal para entendermos como a disregard doctrine foi introduzida em nossa jurisprudência e como atualmente se desenvolve nos diversos ramos do direito brasileiro. A responsabilidade patrimonial deve ser examinada pelas hipóteses de superação da personalidade jurídica, como em casos de falência ou de sócios retirantes, em que se deve avaliar o caso concreto e o ordenamento jurídico para aplicação da teoria em debate. Para tanto, será examinado o desenvolvimento da teoria da desconsideração da personalidade jurídica em nosso ordenamento, bem como sua consolidação nas decisões em diversos ramos do direito até se tornar prática nas decisões proferidas pela justiça do trabalho. Também será avaliada a crescente responsabilização de terceiros (sócios e administradores) de acordo com a vasta legislação existente, a fim de se avaliar como a jurisprudência trabalhista e tributária tem considerado o procurador das empresas, sócios e ex-sócios como responsáveis para o adimplemento de obrigações nesses ramos do direito. Por fim, será feito estudo sobre as decisões trabalhistas recentes para avaliar qual a fundamentação dessa justiça especializada para responsabilizar o procurador pelo pagamento dos créditos decorrentes da relação de trabalho e como tais decisões podem envolver a segurança jurídica das relações empresariais e influenciar as atividades econômicas do país. / The disregard of legal entity doctrine was consolidated in Brazilian Law because of its importance to avoid abuse of the legal entity and deceit committed under the veil of corporate entity and autonomy of equity companies. In this respect, important to explain how the different types of companies under our law relate to the liability of partners and managers, to understand the main reason as to disregard doctrine was introduced in our courts and how currently this develops in different fields of Brazilian law. The personal liability shall be examined by the assumptions of overcoming corporate entity, as in cases of bankruptcy or partners retreatants, in which to value the case and the laws for the application of mentioned doctrine. Thus, we examined the development of the disregard of legal entity doctrine on Brazilian Laws, as well as its consolidation in decisions of various fields of law until become usual in the labor courts decisions. It will also be assessed the increasing liability of partners and managers according to the vast existing law, in order to exam how the labor and tax courts has considered the attorney of companies, partners and ex-partners as responsible for the performance of obligations in these areas of law. Finally, the study will be done on recent labor decisions to assess the reasons for that justice to blame the attorney for the payment of claims from the employment relationship and how such decisions may involve the security of legal relations and corporate influence our economic activities.

O trabalho tem como tema central à análise da dimensão das responsabilidades nos grupos econômicos, bem como a sua interpretação perante os tribunais do trabalho. Busca-se compreender a extensão das obrigações impostas aos grupos e as pessoas que o compõem e acima de tudo, como os tribunais tem decido as questões praticas acerca do tema. As questões que envolvem os Grupos Econômicos têm sido tratadas de diversas formas e sob vários aspectos em nosso ordenamento jurídico. Cada ramo de nosso direito pátrio aborda a questão de acordo com a sua realidade prática, porém, nos casos concretos, a solução dos conflitos muitas vezes prescindem de uma análise mais abrangente. Quando o tema vem à tona, quase sempre repercute em mais de uma esfera, porém, é comum ignorar a essência do instituto e a natureza da questão para buscar a solução apenas sob o ponto de vista do direito que se aborda. Exemplo prático dessa situação é buscar apenas no Direito do Trabalho a solução de um conflito envolvendo o tema Grupo Econômico e a dimensão de suas responsabilidades e das pessoas que o compõem, tudo isso apenas para buscar a satisfação do crédito do trabalhador, como se o Direito do Trabalho servisse apenas para o exercício do pleno de direito de apenas de um dos agentes do pacto social. Embora ainda persista a aplicação estanque do conceito previsto no artigo 2°, § 2° da Consolidação das Leis do Trabalho CLT, os tribunais trabalhistas, principalmente com o advento da Emenda Constitucional 45, vem adotando conceitos outrora utilizados somente em outros ramos do direito. A utilização do instituto da desconsideração da personalidade jurídica (disregard of legal entity) e a aplicação dos conceitos relativos à responsabilidade subjetiva, prevista no artigo 186 do Código Civil e responsabilidade objetiva, inserida no artigo 927, parágrafo único, também do Código Civil, tem servido de importante subsídio aos tribunais trabalhistas para a solução de conflitos ali instaurados. Por outro lado, esses mesmos mecanismos que ajudam na difícil tarefa de entrega de uma prestação jurisdicional e tutela do Estado mais efetivas, também servem, muitas vezes, para justificar a condenação indiscriminada de empresas e pessoas em outros casos. O que se vê, portanto, é que os tribunais trabalhista, prescindem da atualização da legislação trabalhista de modo a coibir que a utilização correta de determinados institutos justifique a equivocada aplicação dos mesmos. / The work has the main topic of the analysis of the dimension of responsibilities on economic groups, as well as its interpretation pursuant Labor Courts. It seeks to understand the extension of obligations imposed to the groups and persons who composed them and above all, how the Courts has been decided those questions regard this topic. The topics involving Economic Groups have been treated by several ways and aspects by our law. Each fields of our parental right address the question using its practical truth, nevertheless on real cases the solution of conflicts oftentimes prescind from a more embracing analysis. When the topic comes up quite often imply more than one field, however it is usual to ignore the substance of the institute and the nature of the question to seek the solution only by the point of view of the right involved in. A practical example of this situation is to seek only in the Labor Right the solution of a conflict involving the topic of Economic Group and the dimension of their responsibilities and persons which are composed by, all of it to seek the satisfaction of the employee`s credit believing that Labor Right only serves to the exercise of the complete right of just one agent of social pact. Notwithstanding still persists the tight application of the concept established in the article 2°, § 2° of Consolidated Labor Laws, the Courts, mainly the Labor Courts after the Constitutional Amendment 45, have been adopting the concepts once applied in other fields of right. Application of the institute of the disregard of legal entity and also the concepts of subjective responsibility established by article 186 of the Civil Code and objective responsibility stated at article 927 also of the Civil Code has been used as an important subside for the Labor Courts in order to solve the conflicts presented there. In the other hand, its mechanisms which use to help on the hard task to delivery a more effective jurisdiction and State protection also contribute several time to justify the indiscriminate condemnation of companies and persons in other cases. What can be seen is the labor courts still prescind from the update of labor laws in order to avoid that the right use of certain institutes justify the wrong application of them.

Stored procedures are used as the current database logic for SAAB’s data model of the fighter aircraft JAS-39 Gripen electrical schemas. Since the database model was developed in 2000, a research and tests needed to be carried out to decide on whether updating the database to today's technology is applicable. Therefore, Object-Relational Mapping (ORM) is to be researched, tested and compared to stored procedures using test-driven development (TDD)concerning an important factor, that Stored procedures are well-known for, which is querying performance of the database. Moreover, how maintainability and flexibility [1] can affect decision between Stored procedures or migrating to ORM based on our subjective experience. NHibernate and Entity Framework are the two ORM solutions considered sinceSAAB uses C# in this project. The process of this project is run using scrum of the agile software development to maintain an iterative progress throughout the project timeline. In this paper, the process and methodology are covered in details and also the comparison with the test results. These results eventually lead us to the answer that ORM is not a suitable technology, and stored procedures still dominate the querying performance for SAAB’scurrent database.

Background: Traditionally text mention normalization corpora have normalized concepts to single ontology identifiers ("pre-coordinated concepts"). Less frequently, normalization corpora have used concepts with multiple identifiers ("post-coordinated concepts") but the additional identifiers have been restricted to a defined set of relationships to the core concept. This approach limits the ability of the normalization process to express semantic meaning. We generated a freely available corpus using post-coordinated concepts without a defined set of relationships that we term "compositional concepts" to evaluate their use in clinical text. Methods: We annotated 5397 disorder mentions from the ShARe corpus to SNOMED CT that were previously normalized as "CUI-less" in the "SemEval-2015 Task 14" shared task because they lacked a pre-coordinated mapping. Unlike the previous normalization method, we do not restrict concept mappings to a particular set of the Unified Medical Language System (UMLS) semantic types and allow normalization to occur to multiple UMLS Concept Unique Identifiers (CUIs). We computed annotator agreement and assessed semantic coverage with this method. Results: We generated the largest clinical text normalization corpus to date with mappings to multiple identifiers and made it freely available. All but 8 of the 5397 disorder mentions were normalized using this methodology. Annotator agreement ranged from 52.4% using the strictest metric (exact matching) to 78.2% using a hierarchical agreement that measures the overlap of shared ancestral nodes. Conclusion: Our results provide evidence that compositional concepts can increase semantic coverage in clinical text. To our knowledge we provide the first freely available corpus of compositional concept annotation in clinical text.

This thesis presents new techniques for data management of run-time data objectsin component-based embedded real-time systems. These techniques enabledata to be modeled, analyzed and structured to achieve data managementduring development, maintenance and execution.The evolution of real-time embedded systems has resulted in an increasedsystem complexity beyond what was thought possible just a few years ago.Over the years, new techniques and tools have been developed to manage softwareand communication complexity. However, as this thesis show, currenttechniques and tools for data management are not sufficient. Today, developmentof real-time embedded systems focuses on the function aspects of thesystem, in most cases disregarding data management.The lack of proper design-time data management often results in ineffectivedocumentation routines and poor overall system knowledge. Contemporarytechniques to manage run-time data do not satisfy demands on flexibility,maintainability and extensibility. Based on an industrial case-study that identifiesa number of problems within current data management techniques, bothduring design-time and run-time, it is clear that data management needs to beincorporated as an integral part of the development of the entire system architecture.As a remedy to the identified problems, we propose a design-time data entityapproach, where the importance of data in the system is elevated to beincluded in the entire design phase with proper documentation, properties, dependenciesand analysis methods to increase the overall system knowledge.Furthermore, to efficiently manage data during run-time, we introduce databaseproxies to enable the fusion between two existing techniques; ComponentBased Software Engineering (CBSE) and Real-Time Database ManagementSystems (RTDBMS). A database proxy allows components to be decoupledfrom the underlying data management strategy without violating the componentencapsulation and communication interface. / INCENSE

Les personnes publiques ne sont pas propriétaires de tous les biens qu’elles utilisent. Elles louent ou empruntent souvent les biens nécessaires à l’exercice de leurs missions. L’utilisation du bien d’autrui n’est plus envisagée comme la solution par défaut qu’elle fut longtemps. A cette fin, les personnes publiques optent pour des procédés juridiques multiples. Titulaires de la capacité à contracter, elles concluent des baux civils ou commerciaux, des prêts à usage ou des usufruits conventionnels. Elles peuvent également recourir à des procédés de droit public, tels que les marchés publics de fournitures ou les marchés de partenariat. Enfin, certains mécanismes non-conventionnels permettent également cette déconnexion entre l’usage et la propriété. En vertu d’une prérogative de puissance publique particulièrement exorbitante, l’administration est habilitée à capter unilatéralement un droit d’usage dans le patrimoine d’autrui, via son pouvoir de réquisition, par exemple. L’aptitude unique de l’administration à jouer ainsi sur plusieurs tableaux est la marque de son irréductible spécificité.L’utilisation du bien d’autrui par une personne publique est en principe le support d’une mission ou d’une tâche d’intérêt général. Pour cette raison, son exécution doit respecter les nécessités de l’action publique, ensemble de principes et exigences juridiques qui impliquent que les activités administratives soient mises en œuvre de manière efficace et sans interruption, à l’aide de moyens adaptés et dans de bonnes conditions financières. A cet égard, l’utilisation du bien d’autrui présente des atouts dont l’exercice du droit de propriété est dépourvu, au moins dans deux circonstances. Les besoins de courte durée, qu’ils soient ponctuels ou discontinus, sont mieux assouvis par la location, le prêt à usage, ou la réquisition, que par l’acquisition d’un bien. La même remarque s’applique, avec quelques nuances, à la satisfaction des besoins complexes de l’administration. Mais la difficile adaptation à l’évolution des besoins et la précarité qui caractérise un nombre important de ces techniques juridiques présente le risque d’une certaine perte de maîtrise, qui peut mettre à mal la continuité, la mutabilité, la « qualité » et la « performance » du service public auquel le bien loué est affecté. Dès lors, le droit public est appelé à réagir. Un régime juridique unifié pourrait être appliqué à l’ensemble des biens utilisés par l’administration, quel qu’en soit le propriétaire, dans le cadre de la mise en œuvre d’une activité de service public. Ces règles s’attacheraient à rendre l’utilisation inviolable, abstraction faite de l’instrument juridique qui fonde l’exercice du droit d’usage ou de jouissance par la personne publique. / Public entities do not own all the goods they use. They often rent or borrow the assets necessary for the performance of their missions. The use of the property of others is no longer considered as the default solution that it was for a long time. To this end, public entities opt for multiple legal processes. Holders of the capacity to contract, they conclude civil or commercial leases, loans or conventional usufruct. They may also use public law procedures, such as public supply contracts or partnership contracts. Finally, some non-conventional mechanisms also allow this disconnection between use and ownership. By virtue of a particularly exorbitant prerogative of public power, the administration is empowered to unilaterally capture a right of use in the patrimony of others, for example, by its power of requisition. The unique ability of the administration to play thus on several tables is the mark of its irreducible specificity.The use of the property of others by a public person is in principle the support of a mission or task of general interest. For this reason, its execution must respect the requirements of public action, a set of principles and legal requirements which imply that administrative activities must be carried out efficiently and without interruption, using appropriate and appropriate means financial conditions. In this respect, the use of the property of others presents assets whose exercise of the right of ownership is devoid, at least in two circumstances. Short-term needs, whether they are punctual or discontinuous, are better satisfied by renting, using loans, or requisitioning than by acquiring property. The same remark applies, with some nuances, to the satisfaction of the complex needs of the administration. But the difficult adaptation to changing needs and the precariousness that characterizes a large number of these legal techniques presents the risk of a certain loss of control, which can undermine continuity, mutability, "quality" and Performance "of the public service to which the leased asset is assigned. Consequently, public law is called upon to react. A unified legal regime could be applied to all property used by the administration, whatever its owner, in the context of the implementation of a public service activity. These rules would aim at making the use inviolable, apart from the legal instrument on which the exercise of the right of use or enjoyment by the public person is based.

Nowadays, knowledge bases are used more and more in Semantic Web tasks, such as knowledge acquisition (Hellmann et al., 2013), disambiguation (Garcia et al., 2009) and named entity corpus construction (Hahm et al., 2014), to name a few. DBpedia is playing a central role on the linked open data cloud; therefore, the quality of this knowledge base is becoming a central point of focus. However, there are some issues with the quality of DBpedia. In particular, DBpedia suffers from three major types of problems: a) invalid types for entities, b) missing types for entities, and c) invalid entities in the resources’ description. In order to enhance the quality of DBpedia, it is important to detect these invalid types and resources, as well as complete missing types. The three main goals of this thesis are: a) invalid entity type detection in order to solve the problem of invalid DBpedia types for entities, b) automatic detection of the types of entities in order to solve the problem of missing DBpedia types for entities, and c) invalid entity detection in order to solve the problem of invalid entities in the resource description of a DBpedia entity. We compare several methods for the detection of invalid types, automatic typing of entities, and invalid entities detection in the resource descriptions. In particular, we compare different classification and clustering algorithms based on various sets of features: entity embedding features (Skip-gram and CBOW models) and traditional n-gram features. We present evaluation results for 358 DBpedia classes extracted from the DBpedia ontology. The main contribution of this work consists of the development of automatic invalid type detection, automatic entity typing, and automatic invalid entity detection methods using clustering and classification. Our results show that entity embedding models usually perform better than n-gram models, especially the Skip-gram embedding model.
