L'encadrement par l'Etat des prérogatives des fédérations sportives françaises

Reynaud, Jean-Baptiste 02 May 2013 (has links) (PDF)
Les fédérations sportives françaises se sont développées en dehors de toute intervention étatique. Elles disposaient alors de prérogatives propres en vue de l'organisation des compétitions de leur discipline sportive. Il découlait de leur statut associatif qu'elles étaient entièrement régies par le droit privé. Néanmoins, à partir d'une jurisprudence du Conseil d'Etat de 1974 entérinant l'existence d'un service public délégué aux structures fédérales, le législateur consacrera progressivement le principe de l'octroi de leurs prérogatives par le ministère chargé des sports au travers de deux actes : l'agrément ministériel et la délégation de service public. Dès lors que la délivrance de ces actes est synonyme de pouvoirs reconnus aux fédérations par le droit étatique et que la délégation mène à la publicisation de leur régime juridique, cette étude a pour objet de dresser la teneur de cet encadrement des prérogatives fédérales. L'agrément et la délégation entraînent pour les fédérations bénéficiaires, diverses sujétions visant à encadrer leur fonctionnement et qui tendent à réduire leur autonomie. Il s'agit d'un encadrement de nature textuelle, contenu au sein de la législation. Bien que ces prescriptions légales se singularisent par leur application uniforme à l'égard de ces fédérations, l'attribution par le ministère des sports de leurs pouvoirs se révèle hétérogène. L'examen de cet encadrement ministériel, appréhendé notamment au travers de sa politique interventionniste à l'égard des disciplines de " boxes pieds poings ", conduit à envisager ses incertitudes ainsi que les pistes d'une réforme de son cadre légal.

Made available in DSpace on 2016-06-02T20:19:19Z (GMT). No. of bitstreams: 1 4746.pdf: 1426086 bytes, checksum: f41b8c37c91b06ab62579658c926ad62 (MD5) Previous issue date: 2012-11-20 / Universidade Federal de Sao Carlos / With the rapid development of civil aviation in Brazil there was a large number of subjects involved in the aircraft maintenance work. Much of workers develop tasks involving manual material handling (MMH), which already have evidenced musculoskeletal risks. However, workers from the aircraft maintenance industry suffer huge pressure due the safety issues and the quality of the work that is performed. There were no studies in the literature that addressed the risk factors present in this sector. Thus, the aim of Study 1 was to evaluate the psychosocial indicators, as well as reports of musculoskeletal symptoms and disorders among workers iof the aircraft maintenance industry. One hundred and one employees were assessed using the Nordic Musculoskeletal Questionnaire, a standardized physical examination, the Job Content Questionnaire and the Utrecht Work Engagement Scale. The results indicate that the workers are exposed to good psychosocial conditions, which have neither prevented the emergence of musculoskeletal disorders, nor the self reported pain and functional disability, particularly associated with the lower back. As the MMH was the main activity performed by the aircraft maintenance workers assessed, musculoskeletal disorders seem to be associated with the biomechanical characteristics of this activity. Despite the risks already identified, the literature suggests some strategies for reducing the physical load imposed to the musculoskeletal system during MMH. These strategies such as the implementation of handles on boxes, ensuring better coupling object/hands during handling. However, the recommendations of adaptations in boxes are not conclusive regarding handle placement, and their impact on workers' musculoskeletal conditions. Thus, the Study 2 was conducted based on a systematic literature review. The aim was to synthesize evidence regarding the effect of adjustment on boxes, aiming at reduction of musculoskeletal load. A survey was conducted in the following databases: Embase, Pubmed / Medline, Web of Science, and Lilacs Bireme CINAHAL, Sportdiscuss, Cochrane. Two reviewers independently selected the relevant studies, and any disagreements were solved by consensus. Cross-sectional studies were included. The scale proposed by Ariens (2000) was used to assess the quality of the studies included in this review. The electronic search yielded a total of 1170 references published in English. At the end of the selection process, and after manual search of references, the selection included 15 cross-sectional studies. Due to do the great methodological variability, regarding both methods and the proposed adaptations (size and mass of boxes), associated with the low quality of the studies prevented the synthesis of evidence. There is a need of using objective and subjective methods to evaluate standardized boxes with handles, which can also be applied to the assessment of other ergonomic interventions. Furthermore, the handles should be investigated using various positions and inclinations, and the MMH has to be carried out to different heights, in order to provide more conclusive evidence to support the implementation of those adaptations in the occupational practice. Experienced subjects have also to be considered in future studies. / Com o desenvolvimento acelerado da aviação civil no Brasil observou-se um elevado número de sujeitos envolvidos com o trabalho de manutenção de aeronaves. Grande parte dos trabalhadores desenvolvem tarefas que envolvem a realização do manuseio de cargas, o qual já tem grandes evidências de riscos musculoesqueléticos. No entanto, o setor de manutenção de aeronaves sofre grandes pressões com a segurança e com a qualidade do trabalho realizado. Não foram encontrados na literatura estudos que abordassem os fatores de risco presentes neste setor. Dessa forma, o Estudo 1 teve como objetivo avaliar os indicadores psicossociais, assim como os relatos de sintomas musculoesqueléticos entre trabalhadores do setor de manutenção de aeronaves. Cento e um funcionários foram avaliados por meio do Questionário Nórdico de Sintomas Osteomusculares, por uma avaliação física padronizada e pelas Escala de Estresse e Trabalho e a Escala de Bem Estar e Trabalho. Os resultados indicam que trabalhadores da indústria de manutenção de aeronaves envolvidos com tarefas de manuseio de materiais são expostos a boas condições psicossociais, o que não impediu o surgimento de distúrbios musculoesqueléticos, nem o alto índice de relato de dor e incapacidade funcional, particularmente associado com a parte inferior da coluna. Como o manuseio de materiais foi a principal atividade realizada no setor de manutenção de aeronaves avaliado, os distúrbios musculoesqueléticos encontrados foram associados às características biomecânicas desta atividade. Apesar dos riscos já identificados, a literatura aponta algumas estratégias para redução da carga física imposta ao sistema musculoesquelético durante o manuseio de cargas. Tratam-se de estratégias nos instrumentos de trabalho, como a implementação de pegas em caixas, garantindo melhor acoplamento objeto/mãos durante o manuseio. No entanto, as adaptações em caixas não são conclusivas em relação às recomendações de posicionamento e sua repercussão nas condições musculoesqueléticas dos trabalhadores. Desta forma, foi realizado o Estudo 2 desta dissertação a partir de uma revisão sistemática da literatura. O objetivo foi sintetizar evidências em relação ao efeito da adaptação de caixas na redução da carga musculoesquelética. Foi realizada pesquisa nas seguintes bases de dados: dados Embase, Pubmed/Medline, Web of Science, Bireme e Lilacs CINAHAL, Sportdiscuss, Cochrane. Dois revisores independentes selecionaram os estudos pertinentes, e as eventuais discordâncias foram solucionadas por consenso. Foram incluídos estudos tranversais. A escala proposta por Ariens (2000) foi utilizada para avaliação da qualidade dos estudos incluídos nesta revisão. A busca eletrônica resultou em um total de 1170 referências publicadas em inglês. Ao final do processo de seleção e da busca manual das referências dos artigos inicialmente incluídos na revisão, totalizou-se a seleção de 15 estudos transversais. A grande variabilidade metodológica, tanto em termos de avaliação como em relação às formas de adaptação de pegas propostas, tamanho e massa das caixas, associadas à baixa qualidade dos estudos incluídos, inviabilizou o agrupamento dos estudos para síntese de evidência. Observa-se a necessidade da utilização conjunta de metodologias objetivas e subjetivas padronizadas na avaliação de caixas adaptadas com pegas, o que pode ser estendido para outros tipos de intervenções ergonômicas. Além disso, as caixas adaptadas precisam ser investigadas a partir de diferentes posicionamentos e inclinações das pegas, a serem manuseadas em diferentes alturas, para fornecer evidências mais definitivas para a implementação na prática ocupacional. A questão da experiência dos sujeitos avaliados também deve ser considerada em estudos futuros.

Promítnutí práva znát svůj původ do českého právního řádu (kritická studie) / Reflection of the right to know one's own origin in the Czech legal order (critical study)

Morongová, Tereza January 2016 (has links)
Abstract, Keywords The thesis concerns itself with the analysis of Czech legislation currently in effect with respect to the right to know one's origin. Discussed are the contents of this right, the legislation's addressees, Article 7 of the Convention on the Rights of the Child including the reservations to it made by the Czech Republic. The affected Czech regulations and their reforms are also talked about. Attention is also given to the issue of determining one's parentage. The bulk of the thesis is made up of analyzing the issues of assisted reproduction, surrogacy, adoption, anonymized and confidential childbirths, and baby boxes in regard to protecting the right to know one's origin. The thesis aims to critically evaluate current legislation, point out its shortcomings and suggest possible future development as the right to know one's origin isn't currently being given enough attention. Some of the aforementioned institutes aren't set out in law at all, others give preference to the anonymity of the child's biological parents. Adoption has recently seen some positive development with the recodification of the civil law, however even this is an area that leaves a lot to be desired as there still are certain faults and deficiencies of the legislation. Keywords: Right to know one's origin, assisted...

Poder de mercado y morosidad en el mercado financiero peruano para los años 2010 al 2019 / Impact of competition on the quality of the financial sector's loan portfolio for the years 2010 – 2019

Soto Zorrilla, Alicia Carolina 20 July 2021 (has links)
Teniendo en cuenta que el sector financiero puede ser un medio para promover el desarrollo económico de un país, influyendo en la inversión de capital hacía actividades productivas y expansión de mercados, analizar posibles determinantes que afecten su desarrollo es importante. El propósito de este trabajo de investigación es determinar si la competencia tiene un efecto en la calidad de la cartera crediticia de las instituciones otorgadoras de crédito, y, de ser así, analizar si el efecto es positivo o negativo. Se toma para el periodo de análisis los años 2010 al 2019 y para tres grupos de instituciones financieras que son banca y, en representación del sector micro financiero, tenemos a las cajas municipales y cajas rurales en el Perú. Estudios previos demostraron una relación en su mayoría positiva entre la tasa de morosidad y el incremento de competencia, sin embargo, no es un resultado concluyente para todos los países y periodos, por lo que determinar la relación para el caso peruano y en los años dados resulta innovador. Para contrastar de forma empírica que la competencia afecta la cartera crediticia, se tomó a la variable de tasa de morosidad para medir el impacto de calidad de cartera. Asimismo, se planteó estimar el índice de Lerner como indicador de poder de mercado en representación de la variable de competencia. Se realizaron las estimaciones con datos de panel, a través del cual, a raíz de las diferentes pruebas econométricas realizadas, se decidió utilizar el método GLS para las regresiones. Los resultados obtenidos permiten validar la hipótesis en que la relación de la competencia entre las instituciones financieras otorgadoras de crédito con la tasa de morosidad es positiva. Finalmente, los resultados obtenidos podrían justificar investigaciones relacionadas a la regulación en el sector financiero con respecto a la competencia bancaria y sus determinantes. / Considering that the financial sector can be a means to promote the economic development of a country, influencing capital investment in productive activities and expansion of markets, analyzing possible determinants that affect its development is important. The purpose of this research work is to determine whether competition influences the quality of the credit portfolio of credit granting institutions, and, if so, to analyze whether the effect is positive or negative. The years 2010 to 2019 are taken for the period of analysis and for three groups of financial institutions that are banks and, representing the microfinance sector, we have the municipal savings banks and rural savings banks. Previous studies have shown a mostly positive relationship between the delinquency rate and the increase in competition; however, it is not a conclusive result for all countries and periods, therefore determining the relationship for the Peruvian case and in the given years it is innovative. To empirically test that competition affects the loan portfolio, the default rate variable was used to measure the impact of portfolio quality. Likewise, it was proposed to estimate the Lerner index as an indicator of market power in representation of the competition variable. The data panel estimates were made, through which, because of the different econometric tests carried out, it was decided to use the GLS method for the regressions. The results obtained allow us to validate the hypothesis that the relationship between the competition between financial institutions granting credit and the delinquency rate is positive. Finally, the results obtained could justify research related to regulation in the financial sector with respect to banking competition and its determinants. / Trabajo de investigación

Complexité de Kolmogorov et corrélations quantiques; étude du carré magique

Berthelette, Sophie 08 1900 (has links)
L'informatique quantique, ce surprenant mariage entre informatique et physique, est un domaine riche en nouvelles idées, autant pour la technologie future qu'une meilleure compréhension de notre univers. C'est le phénomène de l'intrication qui est au coeur de cette nouvelle façon de voir l'information. Ce mémoire porte sur l'étude des corrélations quantiques observées dans la nature, mises de l'avant, entre autres, par John Bell. Plus particulièrement, deux jeux non signalants, dans lesquels ces corrélations se manifestent, sont étudiés: le jeu CHSH, probablement l'exemple le plus connu à ce jour, et le jeu de pseudotélépathie du carré magique. Pour ce faire, deux points de vue seront adoptés, soit probabiliste et algorithmique. Le premier est motivé par la prédiction (ce qui aurait pu se passer), tandis que le second s'intéresse à l'information intrinsèque contenue dans un objet (ce qui s'est passé). Les concepts «aléatoire» et «information» seront donc abordés premièrement à la Shannon (approche probabiliste) puis à la Kolmogorov (approche algorithmique). C'est la complexité de Kolmogorov qui sera utilisée pour quantifier l'information de façon factuelle. De plus, le cas particulier où plusieurs répétitions d'un jeu sont jouées en parallèle dans un monde classique sera examiné. Le théorème des répétitions parallèles, résultat important sur le sujet démontré par Ran Raz, sera présenté et utilisé par la suite dans l'étude algorithmique des jeux CHSH et du carré magique. / Quantum information, this intriguing marriage between computer science and physics, is a promising field of research for future technologies as well as a better understanding of our universe. Entanglement is at the very heart of this new way of understanding information. This thesis focuses on quantum correlations that are observed in nature. They have been studied in great detail by, among others, John Bell. More specifically, two non-signaling games, in which these correlations arise, are studied: the CHSH game, which is probably the best-known example of such games, and the magic square pseudotelepathy game. To do so, two points of view will be adopted: probabilistic and algorithmic. The first is motivated by prediction (what could have happened) and the second focuses on the intrinsic information about an object (what happened). Therefore, the concepts of randomness and information are first addressed from Shannon’s point of view (probabilistic approach) and second from Kolmogorov’s point of view (algorithmic approach). Kolmogorov complexity is used to quantify information in a factual way. Furthermore, the particular case in which multiple repetitions of a game are played in parallel in a classical world is considered. The parallel repetition theorem, an important result on the subject proven by Ran Raz, is presented and used in the algorithmic study of the CHSH game and the magic square game.

Computational and communication complexity of geometric problems

Hajiaghaei Shanjani, Sima 26 July 2021 (has links)
In this dissertation, we investigate a number of geometric problems in different settings. We present lower bounds and approximation algorithms for geometric problems in sequential and distributed settings. For the sequential setting, we prove the first hardness of approximation results for the following problems: \begin{itemize} \item Red-Blue Geometric Set Cover is APX-hard when the objects are axis-aligned rectangles. \item Red-Blue Geometric Set Cover cannot be approximated to within $2^{\log^{1-1/{(\log\log m)^c}}m}$ in polynomial time for any constant $c < 1/2$, unless $P=NP$, when the given objects are $m$ triangles or convex objects. This shows that Red-Blue Geometric Set Cover is a harder problem than Geometric Set Cover for some class of objects. \item Boxes Class Cover is APX-hard. \end{itemize} We also define MaxRM-3SAT, a restricted version of Max3SAT, and we prove that this problem is APX-hard. This problem might be interesting in its own right.\\ In the distributed setting, we define a new model, the fixed-link model, where each processor has a position on the plane and processors can communicate to each other if and only if there is an edge between them. We motivate the model and study a number of geometric problems in this model. We prove lower bounds on the communication complexity of the problems in the fixed-link model and present approximation algorithms for them. We prove lower bounds on the number of expected bits required for any randomized algorithm in the fixed-link model with $n$ nodes to solve the following problems, when the communication is in the asynchronous KT1 model: \begin{itemize} \item $\Omega(n^2/\log n)$ expected bits of communication are required for solving Diameter, Convex Hull, or Closest Pair, even if the graph has only a linear number of edges. \item $\Omega( min\{n^2,1/\epsilon\})$ expected bits of communications are required for approximating Diameter within a $1-\epsilon$ factor of optimal, even if the graph is planar. \item $\Omega(n^2)$ bits of communications is required for approximating Closest Pair in a graph on an $[n^c] \times [n^c]$ grid, for any constant $c>1+1/(2\lg n)$, within $\frac{n^{c-1/2}}{4}-\epsilon$ factor of optimal, even if the graph is planar. \end{itemize} We also present approximation algorithms in geometric communication networks with $n$ nodes, when the communication is in the asynchronous CONGEST KT1 model: \begin{itemize} \item An $\epsilon$-kernel, and consequently $(1-\epsilon)$-\diamapprox~ and \ep -Approximate Hull with $O(\frac{n}{\sqrt{\epsilon}})$ messages plus the costs of constructing a spanning tree. \item An $\frac{n^c}{\sqrt{\frac{k}{2}}}$-Approximate Closest Pair on an $[n^c] \times [n^c]$ grid , for a constant $c>1/2$, plus the cost of computing a spanning tree, for any $k\leq {n-1}$. \end{itemize} We also define a new version of the two-party communication problem, Path Computation, where two parties communicate through a path. We prove a lower bound on the communication complexity of this problem. / Graduate

Artificially Intelligent Black Boxes in Emergency Medicine : An Ethical Analysis

Campano, Erik January 2019 (has links)
Det blir allt vanligare att föreslå att icke-transparant artificiell intelligens, s.k. black boxes, används inom akutmedicinen. I denna uppsats används etisk analys för att härleda sju riktlinjer för utveckling och användning av black boxes i akutmedicin. Analysen är grundad på sju variationer av ett tankeexperiment som involverar en läkare, en black box och en patient med bröstsmärta på en akutavdelning. Grundläggande begrepp, inklusive artificiell intelligens, black boxes, metoder för transparens, akutmedicin och etisk analys behandlas detaljerat. Tre viktiga områden av etisk vikt identifieras: samtycke; kultur, agentskap och privatliv; och skyldigheter. Dessa områden ger upphov till de sju variationerna. För varje variation urskiljs en viktig etisk fråga som identifieras och analyseras. En riktlinje formuleras och dess etiska rimlighet testas utifrån konsekventialistiska och deontologiska metoder. Tillämpningen av riktlinjerna på medicin i allmänhet, och angelägenheten av fortsatt etiska analys av black boxes och artificiell intelligens inom akutmedicin klargörs. / Artificially intelligent black boxes are increasingly being proposed for emergency medicine settings; this paper uses ethical analysis to develop seven practical guidelines for emergency medicine black box creation and use. The analysis is built around seven variations of a thought experiment involving a doctor, a black box, and a patient presenting chest pain in an emergency department. Foundational concepts, including artificial intelligence, black boxes, transparency methods, emergency medicine, and ethical analysis are expanded upon. Three major areas of ethical concern are identified, namely consent; culture, agency, and privacy; and fault. These areas give rise to the seven variations. For each, a key ethical question it illustrates is identified and analyzed. A practical guideline is then stated, and its ethical acceptability tested using consequentialist and deontological approaches. The applicability of the guidelines to medicine more generally, and the urgency of continued ethical analysis of black box artificial intelligence in emergency medicine, are clarified.
