A Sustentabilidade vem se sedimentando como diretriz das compras e contratações públicas, principalmente, após o surgimento da ideia, de que ao Estado cabe reduzir e eliminar padrões insustentáveis de produção e consumo nas suas tomadas de decisões. O objetivo deste estudo foi analisar se o Conselho Nacional de Desenvolvimento Cientifico e Tecnológico pratica a sustentabilidade, por meio das compras e contratações, considerando os constructos das dimensões do desenvolvimento sustentável e as diretrizes preconizadas na legislação brasileira. O método aplicado nesta pesquisa se constituiu em um estudo de caso, exploratório e descritivo, que envolveu a análise entre as variáveis: “contratações públicas” e “critérios de sustentabilidade”. Utilizou-se da pesquisa bibliográfica e documental para a coleta dos dados. Quanto aos processamentos dos dados, utilizou-se da técnica de análise de conteúdo. Os resultados mostram que, ao longo de 2011 a 2015, a variável da sustentabilidade, em suas dimensões - social, ambiental e econômica, tem sido, gradativamente, incorporada aos editais de compras e contratações. Adicionalmente, aponta-se a carência de estudos e de informações, sobre o ciclo de vida de bem ou um serviço sustentável, como barreira ainda a ser enfrentada. / Sustainability has become a solid criterion for public purchases and contracts, especially after the dawn of the concept that the responsibility of reducing and eliminating unsustainable standards for production and consumption falls on the Government. The objective of this study was to analyze whether the National Council of Scientific and Technological Development practices sustainability throughout its purchases and contracts, considering the construct of sustainable development and the guidelines that were preceded by the Brazilian legislation. The method used in this research consisted of an exploratory and descriptive case study, that encompassed the analysis of the variables: “public biddings” and “sustainability criteria”. The data collection used records and bibliographic research. As for the data processing, the technique used was that of content analysis. Results show that, between 2001 and 2015, the sustainability variable in all its dimensions – social, environmental, and economic, has been gradually introduced to the notices of biddings and contracts. Additionally, it points to a lack of studies and information about the life-cycle of goods or sustainable services as a barrier yet to be faced.

A Internet das coisas é constituída de objetos que possuem pequenos sensores e atuadores capazes de interagir com o ambiente. Tais objetos ou coisas estão interconectados entre si e com acesso à Internet por meio de redes com e sem fio. A combinação entre os dispositivos embarcados com sensores e o acesso à Internet possibilita a comunicação dos recursos do mundo físico com o espaço cibernético, desempenhando um papel fundamental na resolução de muitos desafios encontrados na sociedade atual. Porém, a maioria das aplicações existentes são dedicadas a resolver problemas específicos utilizando tais recursos apenas em redes internas, limitando a real capacidade da Internet das Coisas. Diversos trabalhos na literatura propõem a reutilização de tais recursos em forma de serviço por meio de modelos como Dados como Serviço e Sensoriamento como Serviço. Neste contexto, em que potencialmente milhares de recursos podem transferir dados semelhantes de aplicações diferentes, a utilização de técnicas que possam selecionar recursos de forma sensível a contexto torna-se imprescindível. Nesta tese são propostos um conjunto de métodos para melhorar a relação custo-benefício na seleção de recursos em ambientes IoT, auxiliando na tomada de decisão durante a seleção dos recursos que serão ofertados como serviço. Os resultados obtidos por meio de estudos de caso, permitiram a comparação da qualidade da solução e do custo computacional das técnicas aplicadas na seleção de recursos em ambientes IoT, bem como o desenvolvimento de duas novas técnicas para a seleção de recursos, denominadas Elimination Sort e Fast Elimination Sort. / The Internet of Things is composed of objects which have small sensors and actuators capable of interacting with the environment. Such objects or things are interconnected with each other and has access to the Internet through wired and wireless networks. The combination of embedded devices with sensors and access to the Internet become it possible to communicate the resources of the physical world with the cyberspace, playing a key role in solving many challenges found in todays society. However, most existing applications solves a specific problem using its resources just for own purpose, limiting the actual ability of the Internet of Things. Several works propose the reuse of such resources through service models such as Data as Service and Sensing as a Service. In this context, where thousands of resources can transfer similar data from different applications, the use of techniques that can select these features in a context-sensitive way becomes essential. In this thesis, a set of methods to improve the cost-benefit of the process of selection of resources in IoT environments is proposed to support the decision making during resource selection that will be offered as a service. The results obtained through a case study allowed the comparison of the solution quality and the computational cost of the techniques applied for resource selection in IoT environments, as well as the development of two new techniques for the selection of resources called Elimination Sort and Fast Elimination Sort.

Orientador: Fernando Andrade Fernandes / Banca: Antonio Milton de Barros / Banca: José Carlos de Oliveira / Resumo: O presente trabalho versa sobre o delito de apropriação indébita previdenciária, analisado sob a ótica legitimadora do bem jurídico-penal, por referência a determinados critérios político-criminais, com vistas a propiciar uma delimitação do âmbito de intervenção penal, distinguindo-se aquelas condutas cujo grau de ilicitude se restringe ao plano extrapenal daquelas que, por configurarem uma intensa danosidade social, caracterizam um verdadeiro ilícito penal. O trabalho parte da análise sobre a estrutura constitucional da Seguridade Social, a legislação previdenciária em matéria de custeio, bem como aspectos criminológicos e o desenvolvimento do tratamento legal dos crimes contra o sistema de Seguridade Social nos ordenamentos jurídicos estrangeiros e pátrio. Na seqüência, são analisados os critérios de dignidade penal e carência de tutela penal, bem como seus respectivos princípios político-criminais, de modo a se verificar a legitimidade da intervenção penal, particularmente em relação à Previdência Social. Após esse necessário enfoque, chega-se propriamente ao crime de apropriação indébita previdenciária, sendo inicialmente analisados os elementos componentes do tipo penal previsto no art.168-A, §1º, inciso I do Código Penal para que, em seguida, seja enfrentado o núcleo central da pesquisa, a compatibilização do citado delito com a função legitimadora do bem jurídico-penal, possibilitando, no plano da tipicidade material, diferenciá-lo do ilícito administrativo-fiscal. Para tanto, afirma-se que o mero não recolhimento no prazo legal não se mostra suficiente para caracterizar a figura típica, impondo-se a configuração de um plus como elemento diferenciador do simples inadimplemento fiscal. O tipo penal em análise...

This paper starts from the analysis of the Social Insurance constitutional structure, the social security legislation in terms of cost, as well as the crime aspects, and the development of the legal crime treatment against the Social Security according to the alien and native legal systems. Then, the criteria of the penal dignity and lack of criminal tutela, as well as their respective penal-political principles are analyzed in order to verify the legitimacy of the penal intervention, particularly in respect to the Social Security. After this necessary introduction, we get to the Social Security embezzlement crime offense itself, and the component elements of the criminal type of the 168-A sec., § 1I from the Penal Code, so that, afterwards we are able to reach the central part of the research, that is, the compatibility of the mentioned criminal offense with the legitimate power of the criminal legal property, making it possible to differentiate it, to what concerns the matter vagueness doctrine, from the fiscal administrative illicit. To make such differentiation, we state that the simple fact that the collection is not made within the legal term is not enough to characterize criminal offense, being necessary the configuration of a plus as a differentiating element from the simple fiscal default. This criminal offense under analysis should be classified as an improper omission crime, being a must the proof of a previous active conduct to the...

Orientador: Antonio Trajano Menezes Arruda / Banca: Mariana Cláudia Broens / Banca: André Leclerc / Resumo: Este trabalho consiste num esforço para compreender a noção filosófica de identidade pessoal ao longo do tempo. O procedimento para atingir tal compreensão é o de analisar e discutir as principais soluções, encontradas na literatura, que foram propostas para o problema da identidade pessoal. Este problema é descrito como a dificuldade de fundamentar e explicar a nossa crença de que uma pessoa em um dado momento de sua vida e ela em um outro momento são a mesma pessoa, a despeito das grandes alterações biopsicossociais pelas quais ela passa. A primeira solução proposta para este problema é aquela que centra a identidade pessoal em critérios substanciais, que podem ser físicos ou metafísicos. A segunda solução analisada é aquela que recorre à noção de continuidade, seja física, seja psicológica, para buscar explicar como as pessoas permanecem as mesmas ao longo do tempo. Uma terceira solução investigada propõe o entendimento do problema em questão como um problema passível de ser resolvido pela análise linguístico-conceitual; nesta parte, discutimos as seguintes idéias: concepção cética de identidade pessoal, auto-referência, auto-consciência e perspectiva de primeira pessoa. E, por fim, utilizando as noções de auto-organização e de emergência, discutimos as possíveis contribuições da sistêmica na busca de uma solução para o problema. / Abstract: This work consists of an effort to understand the philosophical notion of personal identity over time. The means to reach this understanding is to analyse and to discuss the most important solutions found in the literature that were proposed to the problem of personal identity. This problem is described as the difficulty of grounding and explaining our belief that a person in a given moment of her life and herself in another moment are one and the same person, despite all the great biopsychosocial changes which she undergoes. The first proposed solution to this problem makes substantial criteria, whether physical or metaphysical, central to personal identity. The second solution appeals to the notion of continuity, whether physical or psychological, to explain how people remain the same over time. A third solution suggests that the problem can be solved through linguistic-conceptual analysis; here, we discuss such ideas as the sceptical conception of personal identity, selfreference, self-consciousness and the first-person perspective. And, finally, with the help of the notions of self-organization and emergence, we discuss possible contributions of systemic theory to solving the problem. / Mestre

L'objectif de cette thèse est d'étudier des propriétés des points d'équilibre dans des réseaux de transport multi-critères et de développer des méthodes numériques permettant de trouver l'ensemble des points d'équilibre ou une partie représentative de cet ensemble. Le travail est structure comme suit. Dans le premier chapitre nous donnons une introduction de la thèse. Le chapitre 2 est un rappel de certaines notions que nous utilisons dans les autres. Nous y rappelons le concept de point optimal de Pareto, les fonctions multivoques et les problèmes d'inégalité variationnelle. Nous introduisons certaines fonctions de scalarisation et puis établissons quelques propriétés importantes. Dans le chapitre 3, nous décrivons les réseaux de transport qui sont étudiés dans cette thèse. Dans chaque modèle, nous rappelons les définitions des points d'équilibre et donnons une relation entre ces définitions. Dans le chapitre 4 nous traitons les réseaux de transport multi-critères mono-produit sans contraintes de capacité. Tout d'abord, nous construisons deux problèmes d'optimisation dont les solutions sont exactement l'ensemble des points d'équilibre du modèle initiale et établissons certaines propriétés importantes de continuité et de dérivabilité génériques des fonctions objectifs. Puis nous donnons une formule permettant de calculer le gradient des fonctions objectifs. Nous proposons également un algorithme et prouvons sa convergence pour générer une représentation de l'ensemble des points d'équilibre. Puisque les fonctions objectifs de nos problèmes d'optimisation ne sont pas continues, une méthode de lissage est également considérée afin d'utiliser quelques techniques d'optimisation globale. En fin, nous introduisons le concept de point d'équilibre robuste, puis nous établissons des critères de robustesse et une formule permettant de calculer le rayon de robustesse. Dans le chapitre 5 nous étudions des points d'équilibre vectoriel dans le réseau de transport multi-critères mono-produit sous contraintes de capacité.Tout d'abord, nous proposons un problème d'optimisation équivalent. En utilisant des techniques analogues à celles du chapitre 4 nous obtenons également un sous-ensemble des points d'équilibre du modèle proposé. Dans le dernier chapitre nous considérons des points d'équilibre fort dans le réseau de transport multi-critères multi-produit sous contraintes de capacité. Nous établissons des conditions d'existence des points d'équilibre fort, des relations entre des points d'équilibre fort et des points d'équilibre par rapport à une famille de fonctions ainsi qu'une relation entre des points d'équilibre fort et les points efficaces de l'ensemble des valeurs de la fonction de coût. En plus nous construisons des problèmes d'inéqualité variationnellle, dont les solutions sont les points d'équilibre fort. La dernière partie de ce chapitre est consacrée à un algorithme permettant de trouver des points d'équilibre d'un réseau multi-critères sous contraintes de capacité. Certains exemples numériques sont donnés pour illustrer notre méthode. Nous fermons la thèse avec une liste de références et appendice contenant le code matlab de nos algorithmes. / The purpose of this thesis is to study equilibria in multi-criteria trafficnetworks and develop numerical methods to find the set of all equilibria oronly one representative part of this set. The thesis is structured as follows.In the first chapter we present an introduction of the thesis. Chapter 2is of preliminary character. We recall the concept of Pareto minimal pointsand some notions related to set-valued maps and variational inequality pro-blem. We introduce some scalarizing functions, in particular the so-calledaugmented biggest/smallest monotone functions and augmented signed distance functions, and establish some properties we shall use later.Chapter 3 describes the traffic network models to be studied in this thesis.We define equilibrium for each model and determine a relationship betweenthem. We also give some counter examples for some existing results in therecent literature on this topic.In Chapter 4 we develop a new solution method for multi-criteria net-work equilibrium problems without capacity constraints. To this end we shallconstruct two optimization problems the solutions of which are exactly theset of equilibria of the model, and establish some important generic conti-nuity and differentiability properties of the objective functions. Then we givethe formula to calculate the gradient of the objective functions which enablesus to modify Frank-Wolfe's reduced gradient method to get descent directiontoward an optimal solution. We prove the convergence of the method whichgenerates a nice representative set of equilibria. Since the objective functionsof our optimization problems are not continuous, a method of smoothingthem is also considered in order to see how global optimization algorithmsmay help.We shall also introduce the concept of robust equilibrium, establishcriteria for robustness and a formula to compute the radius of robustness.In Chapter 5 we consider vector equilibrium in the multi-criteria single-product traffic network with capacity constraints.We propose an equivalent optimization problem and establish some im-portant generic continuity and differentiability properties of the objectivefunction. Then we give a formula which allows us to calculate the gradientof the objective function. After that we apply the approach of Chapter 4 toobtain an algorithm for generating equilibria of this network. We also givesome numerical examples to illustrate our approach.In the last chapter we consider strong vector equilibrium in the multi-criteria multi-product traffic network with capacity constraints.We establish conditions for existence of strong vector equilibrium.We alsoestablish relations between equilibrium and efficient points of the value set ofthe cost function and with equilibrium with respect to a family of functions.Moreover we exploit particular increasing functions discussed in Chapter 2 toconstruct variational inequality problems, solutions of which are equilibriumflows. The final part of this chapter is devoted to an algorithm for findingequilibrium flows of a multi-criteria network with capacity constraints. Somenumerical examples are given to illustrate our method and its applicability.A list of references and appendices containing the code Matlab of ouralgorithms follow.

This thesis deals with applications of multi-criteria evaluation of alternatives for creating a benefit system for employees. My work consists of a theoretical part, which describes methods suitable for these purposes. It is a method based on utility function and a method based on the minimum distance from the ideal alternative. The second part describes a complete evaluation process used to evaluate employees who work in accounting and tax consultancy and calculation of their deserved benefits base on the evaluations. In the application the criteria for evaluation of employees, weights of individual criteria were specified and I also counted the amount of utilities for each employee and distances from the ideal employee. The calculation of utilities and distances from the ideal employee were aggregated on the basis of summarizing values for individual companies according to the employees. Profit share of each employee was calculated as the sum of utilities and distances from ideal variant, which was related to work performance for the previous year.
