Cette thèse analyse la dérogation que constitue l’action positive par rapport au principe de l’égalité de traitement, en droit de l’Union européenne. Défini comme une interdiction de discriminer sur le fondement d’un certain nombre de motifs, le principe d’égalité a pourtant vu se multiplier les régimes destinés à écarter son application, dans le droit dérivé qui assure sa mise en œuvre dans les États membres. Parmi ces différents régimes, l’action positive peut permettre l’adoption de traitements référentiels, entre autres mesures, pour les catégories discriminées de la société, afin de remédier aux désavantages qu’elles connaissent, notamment sur le marché du travail. Elle trouve sa légitimité dans un objectif concurrent à celui de l’égalité de traitement par l’indifférenciation de la norme juridique, l’égalité des chances. L’action positive représente donc la seule dérogation à l’égalité justifiée par l’égalité. Cette situation atypique est source de confusion quant à son sens, sa portée et son utilité, dans l’ordre juridique de l’Union comme dans d’autres systèmes. Cette thèse propose des pistes de réflexion pour émanciper l’action positive de la logique dérogatoire qui limite son développement, tout en démontrant son utilité en tant qu’outil de lutte active contre les discriminations et d’intégration sur le marché intérieur dans des conditions égalisées. Elle invite également à dépasser les approches polémiques d’une notion méconnue et souvent dévoyée en France. / This thesis studies the derogatory status of positive action under European Union law, from the principle of equal treatment. Although the principle of equal treatment means that there shall be no discrimination on several prohibited grounds, numerous derogatory and specific regimes, meant to prevent application of this principle, can be found in the secondary legislation implementing it in the member States. Among these various regimes, positive action allows the adoption of preferential treatments for discriminated categories in society, to compensate for the disadvantages they encounter, especially in the labor market. Its legitimacy is founded in the notion of equal opportunities, which competes with the objective of equal treatment by preventing differentiation in norms. Positive action is thus the only derogation from equality justified by equality. This peculiar situation creates a lot of inconsistencies about its meaning, scope, and use, in the European Union legal system and others. This thesis suggests some ways to overcome the derogatory perspective of positive action which restricts its development, while underlining how it represents a useful tool to combat discriminations, favouring integration into internal market on equalized conditions. It also invites to go beyond controversial approaches of a misunderstood and often distorted notion in France.

Solutions journalism, rigorous reporting on responses to social problems, has gained great traction in the last decade. Using positive psychology theory, also known as the theory of well-being, this qualitative study examines the impact of reporting while using solutions journalism techniques. Applying the five pillars of positive psychology theory: positive emotion, engagement, positive relationships, meaning and accomplishment (PERMA), this study used interviews and content analysis to investigate how journalists are applying the tools of solutions journalism as well as what they hope to accomplish in the process. Findings revealed that the application of solutions journalism techniques produces hope and community engagement resulting in flourishing and positive change for individuals, communities and all involved in the reporting process.

Indiana University-Purdue University Indianapolis (IUPUI) / Static code analysis tools are known to flag a large number of false positives. A false positive is a warning message generated by a static code analysis tool for a location in the source code that does not have any known problems. This thesis presents our approach and results in identifying and documenting false positives generated by static code analysis tools. The goal of our study was to understand the different kinds of false positives generated so we can (1) automatically determine if a warning message from a static code analysis tool truly indicates an error, and (2) reduce the number of false positives developers must triage. We used two open-source tools and one commercial tool in our study. Our approach led to a hierarchy of 14 core false positive patterns, with some patterns appearing in multiple variations. We implemented checkers to identify the code structures of false positive patterns and to eliminate them from the output of the tools. Preliminary results showed that we were able to reduce the number of warnings by 14.0%-99.9% with a precision of 94.2%-100.0% by applying our false positive filters in different cases.

No. of bitstreams: 1 Dissert Andréa Perez Corrêa.pdf: 4474805 bytes, checksum: 99bff722994fb17e0e2bac78d51cb56c (MD5) Previous issue date: 2017-03-30 / Ainda é perceptível nos tempos atuais uma ausência de foco nos aspectos positivos dos indivíduos e uma atenção ainda concentrada numa modelagem de liderança voltada para saneamento de déficits de competências. Nesse contexto, as pesquisas da Psicologia Positiva surgem com seus métodos cientificamente rigorosos, aprofundando o estudo dos aspectos positivos das pessoas e sobre uma vida mais significativa e com maior bem-estar. Diante disso, a área do comportamento organizacional constata a possibilidade de migrar para seu arcabouço teórico as descobertas sobre os benefícios comprovados pela Psicologia Positiva e constrói a modelagem do Comportamento Organizacional Positivo, onde o capital psicológico positivo - PsyCap, com seus quatro componentes – esperança, otimismo, autoeficácia e resiliência- surgem como um desdobramento dos capitais do ambiente organizacional, colaborando com uma abordagem mais positiva no contexto do trabalho. Nesse cenário, o objetivo geral desse estudo é, no contexto organizacional brasileiro, mais especificamente na instituição pública Comissão Nacional de Energia Nuclear – CNEN, identificar qual a opinião dos servidores e terceirizados – líderes ou liderados - sobre os possíveis benefícios, que uma postura voltada para o foco e o desenvolvimento do PsyCap pode trazer para o trabalho, verificando se a teoria sobre o tema se confirma ou diverge ao final deste estudo. Para o atingimento deste objetivo, foi desenvolvida uma pesquisa exploratória, levando-se em consideração a embrionária aplicação do tema capital psicológico positivo no Brasil, o que permitiu uma análise do fenômeno de forma mais investigativa. Por meio de uma pesquisa on line, sugerida com participação voluntária ao universo de 2.959 servidores e terceirizados de todas as unidades da CNEN, foi aplicado questionário de pesquisa com perguntas elaboradas com base na revisão da literatura, tendo sido alcançada uma amostra de 232 respondentes. Os dados estatísticos permitiram chegar a resultados generalizáveis de que há uma percepção positiva por parte dos respondentes sobre a aplicabilidade do PsyCap, no que tange aos benefícios que podem trazer ao trabalho, sobre a geração de benefícios com a aplicação de uma intervenção/treinamento com essa temática e sobre a aptidão de lideres no trato de uma abordagem com PsyCap. Além disso, foram identificados os componentes individuais e do trabalho que podem favorecer o aumento dos índices do Psycap e como o índice de PsyCap dos líderes pode favorecer e em que termos o ambiente de trabalho em algumas variáveis. O presente estudo traz enorme contribuição para: uma possível aplicabilidade de iniciativas no ambiente organizacional da CNEN e provavelmente em outras instituições com perfil similar; conhecimento para a construção de um modelo de intervenção/treinamento customizada aos ambientes do serviço público federal que possam vir a ser generalizáveis em outras empresas com configuração distinta; a geração de novos conhecimentos sobre o PsyCap no contexto nacional e incentivo a novas pesquisas acadêmicas com a temática do PsyCap no Brasil. / A lack of focus on the positive aspects of individuals is still perceptible, and attention is still focused on leadership modeling, aimed at sanitizing skills deficits. In this context, Positive Psychology research emerges with its scientifically rigorous methods, deepening the study of positive aspects of people and a more meaningful and well-being life. Thus, the area of organizational behavior shows the possibility of migrating to its theoretical framework the findings about the benefits of Positive Psychology and builds the Positive Organizational Behavior modeling, where positive psychological capital - PsyCap, with its four components - hope, Optimism, self-efficacy, and resilience-emerged as an unfolding of the capitals of the organizational environment, collaborating with a more positive approach in the context of work. In this scenario, the general objective of this study is, in the Brazilian organizational context, more specifically in the public institution CNEN, to identify the opinion of the servers and outsourced - leaders or commanded - about the possible benefits that a posture focus and development of PsyCap can bring to the work, checking whether the theory on the topic is confirmed or diverges at the end of this study. To achieve this objective, an exploratory research was developed, taking into account the embryonic application of the positive psychological capital theme in Brazil, which allowed an analysis of the phenomenon in a more investigative way. Through an online survey, suggested with voluntary participation to the universe of 2,959 servers and outsourced of all the units of CNEN, a questionnaire of research was applied with questions elaborated based on the literature review, having been reached a sample of 232 respondents. The statistical data allowed us to reach generalizable results that there is a positive perception by the respondents about the applicability of PsyCap, regarding the benefits that can bring to work, about the generation of benefits with the application of an intervention / training with this And on the aptitude of leaders in dealing with a PsyCap approach. In addition, we identified the individual and work components that may favor the increase of the Psycap indexes and how the PsyCap index of the leaders can favor and in what terms the work environment in some variables. The present study presents a great help for: the possible applicability of initiatives in the organizational environment of CNEN and probably in other institutions with similar profile; Knowledge for the construction of a model of intervention / personalized training for the environments of the federal public service that can be generalizable in other companies with different configuration; The generation of new knowledge about PsyCap in the national context and the encouragement of new academic research with PsyCap in Brazil.

Positive systems, which carry the well known property of confining the state, output, and/or input variables to the nonnegative orphant, are of great practical importance, as the nonnegative property occurs quite frequently in numerous applications and in nature. These type of systems frequently occur in hydrology where they are used to model natural and artificial networks of reservoirs; in biology where they are used to describe the transportation, accumulation, and drainage processes of elements and compounds like hormones, glucose, insulin, and metals; and in stocking, industrial, and engineering systems where chemical reactions, heat exchanges, and distillation processes take place. The interest of this dissertation is in two key problems: positive stabilization and the positive servomechanism problem. In particular, this thesis outlines the necessary and sufficient conditions for the stabilization of positive linear time-invariant (LTI) systems using state feedback control, along with providing an algorithm for constructing such a stabilizing regulator. Moreover, the results on stabilization also encompass the two problems of the positive separation principle and stabilization via observer design. The second, and most emphasized, problem of this dissertation considers the positive servomechanism problem for both single-input single-output (SISO) and multi-input multi-output (MIMO) stable positive LTI systems. The study of the positive servomechanism problem focuses on the tracking problem of nonnegative constant reference signals for unknown/known stable SISO/MIMO positive LTI systems with nonnegative unmeasurable/measurable constant disturbances via switching tuning clamping regulators (TcR), linear quadratic clamping regulators (LTQcR), and ending with MPC control. Finally, all theoretical results on the positive servomechanism problem are justified via numerous experimental results on a waterworks system.
