O princípio majoritário e a fundamentação da autoridade e da legitimidade do direito democrático segundo Jeremy WaldronBaldin, Mateus de Campos January 2015 (has links)
Em seu Law and Disagreement, Jeremy Waldron apresenta o que denomina de uma teoria democrática do direito, uma teoria normativa sobre a autoridade do direito baseada em sua legitimidade democrática. Para Waldron é a legitimidade do direito enquanto fruto de um processo de deliberação e votação majoritária que sustenta sua autoridade. Esse trabalho busca explicar a teoria democrática do direito de Waldron apresentando-a no contexto do liberalismo e do positivismo normativo. Dada a importância da legitimidade para a autoridade do direito em Waldron, esse trabalho discute também o que Waldron entende por legitimidade e sua distinção em relação à justificação, e defende a teoria de Waldron acerca da legitimidade como superior a outra teoria semelhante, defendida por John Simmons. Esse trabalho apresenta a teoria democrática do direito de Waldron no contexto das denominadas circunstâncias da política – a necessidade sentida de uma decisão comum e o desacordo sobre qual deve ser essa decisão. Essa tese defende que Waldron apresenta dois argumentos distintos em defesa de sua teoria: a) um argumento epistêmico, baseado na tese da justificação normal da autoridade, de Joseph Raz, adaptada ao contexto das decisões majoritárias, e que está suscetível a certos tipos de crítica, e b) um argumento de equidade, que recorre à igual consideração e respeito nas circunstâncias da política, o qual está suscetível a outros tipos de crítica. Essa tese defenderá que, dependendo do argumento, a posição de Waldron levará a distintos resultados teóricos e práticos (normativos). / In his Law and Disagreement, Jeremy Waldron presents what he names a democratic jurisprudence, a normative theory about the authority of law based in his democratic legitimacy. To Waldron, it is the legitimacy of law as a result of a process of deliberation and majoritarian voting that sustains its authority. This work seeks to explain Waldron’s democratic jurisprudence presenting it in the context of liberalism and normative positivism. Since legitimacy is important to the authority of law, this work also discuss what Waldron understands by legitimacy and its distinction from justification, and defends that Waldron’s theory about legitimacy is superior to another similar theory, defended by John Simmons. This work presents Waldron’s democratic jurisprudence in the context of the said circumstances of politics - the felt need for a common decision and the disagreement about what ought to be this decision. This thesis defends that Waldron presents two distinct arguments in defense of his theory: a) an epistemic argument, that is based on the normal justification thesis of Joseph Raz adapted to the context of majoritarian decision, and that is susceptible to certain kinds of critic, and b) an argument of fairness, that calls for equal considerations and respect in the circumstances of politics, and that is susceptible to other kinds of critic. This thesis will defend that, depending on the argument, Waldron’s position will lead to distinct theoretical and practical (normative) results.

I en digitaliserad kapitalmarknad : En studie om finansiella behov och relationer inom andelsbaserad crowdfundingHenricson, Elin, Mertsalmi, Veera January 2017 (has links)
Equity crowdfunding, which has primarily been developed by private operators, is considered as an alternative financing form where capital is raised from a group of individuals through digital platforms. In the absence of formal regulations and existing high information asymmetries between businesses and crowd-investors, businesses need to build up legitimacy and trust through social actions. In this way, knowing the main participants and developing good relationships with them, become key factors for crowdfunding success. The purpose of this thesis is to examine equity crowdfunding and its context by identifying and describing stakeholders that interact there. In particular, this thesis aims to describe relationships that are being developed between businesses and their crowd-investors. The data has been collected through interviews with both businesses and investors that have experience in using equity crowdfunding in a Swedish context. The interview data have been analysed by using the stakeholder theory. This has helped us to identify and characterise several stakeholders that exist in the context of equity crowdfunding. Especially, two stakeholder management approaches – arm length- and fairness approach - have been chosen as the analytical tools for this thesis. These categories have primarily been used to analyse relationships that are being developed between businesses and crowd-investors. Our discussion highlights equity crowdfunding as a new and alternative type of capital market, where participants act more cooperatively and have versatile roles. As a financial tool, equity crowdfunding opens up possibilities for closer interaction between businesses and investors. As a consequence of high information asymmetries, developing relationships and creating a transparent environment through active communication, become particularly important for businesses. However, our data has shown us that in reality the collaborative relationship depends on how much businesses allow to be influenced by investors as well as how much the investors request participation.

Contribuições para a análise e simulação de redes ópticas: aspectos de Engenharia de Tráfego, restauração dinâmica e conversão de comprimentos de onda / Contributions for the analysis and simulation of optical networks: aspects of traffic engineering, dynamic restoration and conversion of wavelenghtsEduardo José Aloia 09 March 2009 (has links)
A tecnologia WDM (Wavelength Division Multiplexing) e a introdução de OXCs (Optical Cross Connect) e OADMs (Optical Add/Drop Multiplexer) puramente ópticos podem dotar as redes ópticas da função de networking, ou seja, da capacidade de manipular comprimentos de onda de forma a implementar o roteamento destes. Esta possibilidade implica em uma nova forma de relacionamento das aplicações com a camada física, sendo a arquitetura GMPLS candidata a estabelecer tal relacionamento. Soluções eficientes para o problema de alocação de recursos e roteamento de tráfego tornam-se uma necessidade imperiosa em projeto, expansão e gerenciamento de redes ópticas. A contribuição desta tese consiste em relacionar funcionalidades tais como: agregação (grooming) de tráfego, mecanismo de controle de admissão de chamadas (CAC), mecanismos de restauração e alocação de conversores em redes ópticas heterogêneas, avaliando-se as métricas de probabilidade de bloqueio, probabilidade do tráfego bloqueado e imparcialidade (fairness). Tais funcionalidades são tratadas separadamente na literatura. Com este objetivo em mente modela-se a rede com duas camadas: a camada física e a camada virtual. Estabelecem-se duas políticas de agregação de tráfego MrTV (minimização da rota na topologia virtual) e MrTF (minimização da rota na topologia física) e analisa-se o desempenho destas em relação à porcentagem de tráfego bloqueado. Em seguida um mecanismo de controle de admissão de chamadas (CAC) é implementado e sua influência em termos de imparcialidade (fairness) e probabilidade de bloqueio é analisada. A simulação e análise de redes ópticas, como a Rede NSFnet e a Rede Nacional Italiana são executadas por meio da implementação de um grafo baseado em Zhu e Mukherjee [28]. Como resultado, a política MrTF apresenta menor porcentagem de tráfego bloqueado do que a política MrTV para as redes simuladas e a implementação de um mecanismo de janela deslizante (rolling window) tornou o mecanismo de CAC mais otimizado. A utilidade de se implantar conversores de comprimento de onda apenas em alguns nós da rede (conversão esparsa) é estudada e uma análise sobre a probabilidade de bloqueio e a imparcialidade da rede desta distribuição de conversores é apresentada. Finalmente, técnicas de restauração na camada física e virtual são implementadas e uma análise da influência destes sobre a probabilidade de bloqueio e a imparcialidade da rede é executada. / The Wavelength Division Multiplexing (WDM) technology as well as both the introduction of all optical OXCs (Optical Cross Connect) and OADMs (Optical Add/Drop Multiplexer) may provide the optical network with the networking function, i.e, the capacity to manipulate wavelengths in order to implement their routing. This possibility implies a new type of relationship between applications and the physical layer. The likely candidate to establish such relationships is GMPLS architecture. Efficient solutions to both the problems of allocating resources and traffic routing become an enhanced requirement in the design, expansion and management of optical networking. The present study focus at the relationship between functionalities such as traffic grooming, network fairness improvement, protection/restoring mechanisms and wavelength conversion in heterogeneous optical networks, evaluating the metrics of blocking probability, probability of traffic blocked and fairness. These functionalities are separately treated in literature. With this goal in mind, a two-layer representation is used in order to model the network: the physical and virtual layers, respectively. Two policies on traffic grooming are set up, as follows: MrTV (route minimizing on virtual topology) and MrTF (route minimizing on physical topology). The performance of such policies is analyzed regarding the percentage of blocked traffic. Next, a mechanism for call admission control (CAC) is implemented and its influence in terms of fairness and blocking probability is discussed. The simulations of optical networks such as NSFnet and the Italian National Network are carried out through a graph based in Zhu and Mukherjee [28]. As a result, MrTF policy presents a smaller percentage of blocked traffic than the MrTV for the simulated networks and the rolling window mechanism has allowed the optimization of the call admission control (CAC) mechanism. The usefulness of placing wavelength converters in a few networks nodes (spare conversion) is studied and an analysis on the blocking probability is presented. Next, the network fairness for this distribution of wavelength converters is presented. Finally, techniques for restoring both physical and virtual layers are also implemented and an analysis regarding their influence on the blocking probability and the network fairness is carried out.

Previous issue date: 2008-07-04 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The objective of the present work consists in the investigation and exhibition of the conception of the original position in the theory of justice as fairness, drawn by John Rawls. For that, it is highlighted the way the author exhibits the agreement made in this initial situation of the choice, in other words, the parts symmetrically situated in the original position and covered by the veil of ignorance, that has the function to impede the passage of arbitrary information that can influence in the choice of the principles. Besides, the agreement made in the original position is characterized as hipothetical and non-historical. Rawls, in the subsequent works of A Theory of Justice, emphasizes that the misunderstanding about the hypothetical aspect of this position is due to the fact it isn´t seen as a representation artifice. By this way , in order to understand the argumentation about the original position, it treats the doctrines, in which the theory of justice as fairness, is presented as an alternative, with the intent to contextualize the theory of Rawls. From the works of the own author, it looks for presenting the fundamental ideas and the way how they are linked in this theory. Besides, they are object of study the role and the characteristics of this initial situation of the choice and the principles of justice, as the result of the agreement made between the parts in the original position, are objects of the study. This position is understood as an initial situation of the suitable equality for the choice of the principles, that must specify the fair terms of the society understood as a system of social cooperation. / O objetivo do presente trabalho consiste na investigação e exposição da concepção de posição original na teoria da justiça como eqüidade, elaborada por John Rawls. Para isso, destaca a maneira como o autor expõe o acordo realizado nesta situação inicial de escolha, ou seja, as partes simetricamente situadas na posição original e encobertas pelo véu de ignorância, que tem como função impedir a passagem de informações arbitrárias que possam influenciar na escolha dos princípios. Além disso, o acordo realizado na posição original é caracterizado como hipotético e a-histórico. Rawls, nas obras posteriores a Uma Teoria da Justiça, destaca que o mal-entendido quanto ao aspecto hipotético desta posição está no fato dela não ser vista como um artifício de representação. Desta forma, a fim de compreender a argumentação acerca da posição original, trata-se das doutrinas nas quais a teoria da justiça como eqüidade é apresentada como uma alternativa, com o intuito de contextualizar a teoria de Rawls. A partir das obras do próprio autor, procura apresentar as idéias fundamentais e a forma como estão interligadas nesta teoria. Além disso, são objetos de estudo o papel e as características dessa situação inicial de escolha e os princípios de justiça, como o resultado do acordo realizado entre as partes na posição original. Esta posição é compreendida como uma situação inicial de igualdade adequada para a escolha dos princípios, que devem especificar os termos eqüitativos da sociedade compreendida como um sistema de cooperação social.

Trigger warnings: likabehandling eller ett hot mot utbildningsväsendet? : en argumentationsanalys av den svenska offentliga debattenWidlund, Benjamin January 2016 (has links)
Trigger warnings as a concept is mainly a tool to make students aware of potentially triggering content in literature and has its origin in internet adaptions of psychological theories of posttraumatic stress disorder. The aim of this essay was to describe and analyse the argumentation in the public debate over trigger warnings in Sweden and to illustrate the fundamental questions relating to education that is highlighted by it. This was done through argumentation analysis and with theories of liberalism and identity politics as poles of a dimension of justice, illustrated by two different perspectives on disability pedagogy. The material chosen consisted of nine articles, radio programs and televised debates. The results show a clear tendency for advocates of trigger warnings to lean towards identity politics and a critical perspective on disability pedagogy in their argumentation, while the critics firmly represented a liberal, universalist perspective along with a compensatory perspective on disability pedagogy in theirs. Three fundamental questions arose in the debate: first, safety in the realm of education, meant as void of feelings of being offended, was viewed as essential by the authors who were pro trigger warnings and as a threat to the sole purpose of education by those who were against it. Second, the importance of a diagnosis for disability pedagogy, where those against stressed the importance of a diagnosis, the lack of which in combination with a request for a trigger warning was viewed as being easily offended. Advocates on the other hand were uninterested in diagnoses. Finally, the relation between free speech and democratic values in the educational system and in the society as a whole, where those authors favouring trigger warnings tended to view free speech as less fundamental than those opposed, who instead saw trigger warnings as a threat.

Efficient optimal multiprocessor scheduling algorithms for real-time systemsNelissen, Geoffrey 08 January 2013 (has links)
Real-time systems are composed of a set of tasks that must respect some deadlines. We find them in applications as diversified as the telecommunications, medical devices, cars, planes, satellites, military applications, etc. Missing deadlines in a real-time system may cause various results such as a diminution of the quality of service provided by the system, the complete stop of the application or even the death of people. Being able to prove the correct operation of such systems is therefore primordial. This is the goal of the real-time scheduling theory.<p><p>These last years, we have witnessed a paradigm shift in the computing platform architectures. Uniprocessor platforms have given place to multiprocessor architectures. While the real-time scheduling theory can be considered as being mature for uniprocessor systems, it is still an evolving research field for multiprocessor architectures. One of the main difficulties with multiprocessor platforms, is to provide an optimal scheduling algorithm (i.e. scheduling algorithm that constructs a schedule respecting all the task deadlines for any task set for which a solution exists). Although optimal multiprocessor real-time scheduling algorithms exist, they usually cause an excessive number of task preemptions and migrations during the schedule. These preemptions and migrations cause overheads that must be added to the task execution times. Therefore, task sets that would have been schedulable if preemptions and migrations had no cost, become unschedulable in practice. An efficient scheduling algorithm is therefore an algorithm that either minimize the number of preemptions and migrations, or reduce their cost.<p><p>In this dissertation, we expose the following results:<p>- We show that reducing the "fairness" in the schedule, advantageously impacts the number of preemptions and migrations. Hence, all the scheduling algorithms that will be proposed in this thesis, tend to reduce or even suppress the fairness in the computed schedule.<p><p>- We propose three new online scheduling algorithms. One of them --- namely, BF2 --- is optimal for the scheduling of sporadic tasks in discrete-time environments, and reduces the number of task preemptions and migrations in comparison with the state-of-the-art in discrete-time systems. The second one is optimal for the scheduling of periodic tasks in a continuous-time environment. Because this second algorithm is based on a semi-partitioned scheme, it should favorably impact the preemption overheads. The third algorithm --- named U-EDF --- is optimal for the scheduling of sporadic and dynamic task sets in a continuous-time environment. It is the first real-time scheduling algorithm which is not based on the notion of "fairness" and nevertheless remains optimal for the scheduling of sporadic (and dynamic) systems. This important result was achieved by extending the uniprocessor algorithm EDF to the multiprocessor scheduling problem. <p><p>- Because the coding techniques are also evolving as the degree of parallelism increases in computing platforms, we provide solutions enabling the scheduling of parallel tasks with the currently existing scheduling algorithms, which were initially designed for the scheduling of sequential independent tasks. / Doctorat en Sciences de l'ingénieur / info:eu-repo/semantics/nonPublished

Inter-cell interference coordination in wireless networks / Coordination des interférences intercellulaires dans les réseaux sans-filYassin, Mohamad 13 November 2015 (has links)
Grâce aux avancées technologiques dans le domaine des réseaux cellulaires et des équipements mobiles, le nombre d'applications multimédia à haut débit dans les réseaux mobiles ne cesse d'augmenter. On prévoit que le trafic de données dans les réseaux mobiles en 2017 sera 13 fois plus important que celui en 2012. Pour satisfaire aux besoins des équipements mobiles, de nouvelles approches pour la gestion des ressources radio et des puissances de transmission sont requises.Dans le cadre de cette thèse, on s'intéresse à proposer des solutions pour remédier aux problèmes des interférences intercellulaires dans les réseaux mobiles de dernière génération. Nous enquêtons d'une manière exhaustive les différentes techniques de coordination des interférences intercellulaires existantes. Ces techniques sont qualitativement comparées, puis classées selon le taux de coopération requis entre les différentes stations de base, mais aussi selon leurs principes de fonctionnement. Nous abordons également le problème multicellulaire d'allocation des ressources et des puissances de transmission d'une manière centralisée. Nous formulons ce problème d'optimisation centralisé, puis nous le décomposons en deux sous-problèmes indépendants : l'allocation de ressources et l'allocation des puissances de transmission. De plus, une approche distribuée basée sur la théorie des jeux est proposée pour l'allocation des puissances de transmission. Les techniques centralisées de minimisation des interférences intercellulaires offrent la solution optimale au prix d'une grande charge de signalisation. Par contre, les solutions décentralisées réduisent le trafic de signalisation sans garantir l'optimalité de la solution obtenue. Nous proposons ensuite une heuristique de contrôle de puissance qui modifie localement l'allocation des puissances de transmission de manière à éviter le gaspillage d'énergie et pour réduire les interférences ressenties par les utilisateurs des stations de base voisines. Nous proposons également une technique autonome qui gère la distribution des ressources radio entre les différentes zones de chaque cellule. Cette technique répond aux besoins des utilisateurs dans chaque zone en adaptant la distribution des ressources d'une manière dynamique. Nous abordons aussi le compromis entre les techniques de gestion d'interférences intercellulaires centralisées et décentralisées. Nous proposons une approche hybride où l'allocation des ressources radio et des puissances de transmission est faite d'une manière coopérative entre les différentes cellules. Dans un premier lieu, les cellules voisines collaborent afin d'ajuster les puissances de transmission allouées aux ressources radio. Ensuite, la distribution des ressources entre les différentes zones de chaque cellule est modifiée localement, selon les besoins des utilisateurs dans chaque zone. / The exponentially increasing demand for mobile broadband communications have led to the dense deployment of cellular networks with aggressive frequency reuse patterns. The future Fifth Generation (5G) networks are expected to overcome capacity and throughput challenges by adopting a multi-tier architecture where several low-power Base Stations (BSs) are deployed within the coverage area of the macro cell. However, Inter-Cell Interference (ICI) caused by the simultaneous usage of the same spectrum in different cells, creates severe problems. ICI reduces system throughput and network capacity, and has a negative impact on cell-edge User Equipment (UE) performance. Therefore, Inter-Cell Interference Coordination (ICIC) techniques are required to mitigate the impact of ICI on system performance. In this thesis, we address the resource and power allocation problem in multiuser Orthogonal Frequency Division Multiple Access (OFDMA) networks such as LTE/LTE-A networks and dense small cell networks. We start by overviewing the state-of-the-art schemes, and provide an exhaustive classification of the existing ICIC approaches. This qualitative classification is followed by a quantitative investigation of several interference mitigation techniques. Then, we formulate a centralized multi-cell joint resource and power allocation problem, and prove that this problem is separable into two independent convex optimization problems. The objective function of the formulated problem consists in maximizing system throughput while guaranteeing throughput fairness between UEs. ICI is taken into account, and resource and power allocation is managed accordingly in a centralized manner. Furthermore, we introduce a decentralized game-theoretical method to solve the power allocation problem without the need to exchange signaling messages between the different cells. We also propose a decentralized heuristic power control algorithm based on the received Channel Quality Indication (CQI) feedbacks. The intuition behind this algorithm is to avoid power wastage for UEs that are close to the serving cell, and reducing ICI for UEs in the neighboring cells. An autonomous ICIC scheme that aims at satisfying throughput demands in each cell zone is also introduced. The obtained results show that this technique improves UE throughput fairness, and it reduces the percentage of unsatisfied UEs without generating additional signaling messages. Lastly, we provide a hybrid ICIC scheme as a compromise between the centralized and the decentralized approaches. For a cluster of adjacent cells, resource and power allocation decisions are made in a collaborative manner. First, the transmission power is adjusted after receiving the necessary information from the neighboring cells. Second, resource allocation between cell zones is locally modified, according to throughput demands in each zone.

We Only Accept Online Applications: The Effect of HRIS E-Recruitment Technology on Job-Seeker Fairness Perceptions in the Canadian Federal Public SectorWesolowski, Peter January 2016 (has links)
Industrial-organizational psychologist Stephen S.W. Gilliland developed a model for studying job-seeker fairness perceptions in 1993 based on existing research in organizational justice. The model includes several rules which will result in job-seeker perceptions of fairness if satisfied and job-seeker perceptions of unfairness if violated. Given the prominence of this model in the literature as well as changes which have occurred in personnel selection (such as human resource information systems, or HRIS, and e-recruitment), scholars have called for a technological re-envisioning of the original model, especially the explanations/descriptions ascribed to each rule. The present study seeks to understand how HRIS e-recruitment technology impacts job-seeker fairness perceptions and in so doing update the Gilliland (1993) model using a qualitative methodology and website success measures from information systems success theory. It contributes to the literature on applicant fairness perceptions by accounting for technological change, and contributes to the field of Public Administration by studying a governmental e-recruitment portal thereby accounting for the particularities of public-sector HRM which is underrepresented in the organizational justice literature. Over the course of one (1) year, twelve (12) job-seekers participated in a series of focus group interviews where they reflected on their experiences applying for jobs in the Canadian federal civil service using the government’s e-recruitment portal. Participants completed profiles, sent applications, communicated with government personnel, and wrote internet tests, among other job-search activities, and reported on their experiences from the perspective of fairness. Results confirm the validity of all original procedural justice rules and offer insight into their application in a recruitment environment where applicants invest considerable time interacting with computerized systems. Two additional rules are also put forth including the ease with which candidates can deceive tests and privacy/trustworthiness using technology. The findings are limited insofar as data gathering took place during a time of reduced hiring activity by the employer and because participation was limited to one (1) specific geographic location.
