The Application of a Pluralist Approach of Global Administrative Law on the Governance of Doping in Sport

Plusieurs problèmes liés à l'utilisation de substances et méthodes interdites de dopage dans les sports posent de grands défis à la gouvernance antidopage. Afin de lutter contre le dopage, certains pays ont mis en oeuvre des cadres juridiques basés exclusivement sur le droit pénal tandis que d'autres pays ont plutôt misé sur des mécanismes et organismes spécialisés trouvant fondement en droit privé ou sur un régime hybride de droit public et privé. Ces différentes approches réglementaires ont pour conséquence de faire en sorte qu’il est très difficile de lutter efficacement contre le dopage dans les sports, notamment parce que leur exécution requiert un degré de collaboration internationale et une participation concertée des autorités publiques qui est difficile à mettre en place. À l’heure actuelle, on peut par exemple observer que les États n’arrivent pas à contrer efficacement la participation des syndicats et organisations transnationales liés au crime organisé dans le marché du dopage, ni à éliminer des substances et méthodes de dopage interdites par la réglementation. Par ailleurs, la gouvernance antidopage basée sur les règles prescrites par l’Agence mondiale antidopage prévoit des règles et des normes distinctes de dopage distinguant entre deux catégories de personnes, les athlètes et les autres, plaçant ainsi les premiers dans une position désavantageuse. Par exemple, le standard de responsabilité stricte sans faute ou négligence imposé aux athlètes exige moins que la preuve hors de tout doute raisonnable et permet l'utilisation de preuves circonstancielles pour établir la violation des règles antidopages. S'appliquant pour prouver le dopage, ce standard mine le principe de la présomption d'innocence et le principe suivant lequel une personne ne devrait pas se voir imposer une peine sans loi. D’ailleurs, le nouveau Code de 2015 de l’Agence attribuera aux organisations nationales antidopage (ONADs) des pouvoirs d'enquête et de collecte de renseignements et ajoutera de nouvelles catégories de dopage non-analytiques, réduisant encore plus les droits des athlètes. Dans cette thèse, nous discutons plus particulièrement du régime réglementaire de l’Agence et fondé sur le droit privé parce qu’il ne parvient pas à répondre aux besoins actuels de gouvernance mondiale antidopage. Nous préconisons donc l’adoption d’une nouvelle approche de gouvernance antidopage où la nature publique et pénale mondiale du dopage est clairement reconnue. Cette reconnaissance combiné avec un modèle de gouvernance adapté basé sur une approche pluraliste du droit administratif global produira une réglementation et une administration antidopage mieux acceptée chez les athlètes et plus efficace sur le plan des résultats. Le nouveau modèle de gouvernance que nous proposons nécessitera toutefois que tous les acteurs étatiques et non-étatiques ajustent leur cadre de gouvernance en tenant compte de cette nouvelle approche, et ce, afin de confronter les défis actuels et de régler de manière plus satisfaisante les problèmes liés à la gouvernance mondiale du dopage dans les sports.

Analysis Of Semi-Distributed And Global Hydrological Models In The Central Tropical Basins Of The Gulf Of Mexico To The Effects Of Extreme Hydrometeorological Phenomena

In the last years extreme hydrometeorological phenomena have increased in number and intensity affecting the inhabitants of various regions, an example of these effects are the central basins of the Gulf of Mexico (CBGM) that they have been affected by 55.2% with floods and especially the state of Veracruz (1999-2013), leaving economic, social and environmental losses. Mexico currently lacks sufficient hydrological studies for the measurement of volumes in rivers, since is convenient to create a hydrological model (HM) suited to the quality and quantity of the geographic and climatic information that is reliable and affordable. Therefore this research compares the semi-distributed hydrological model (SHM) and the global hydrological model (GHM), with respect to the volumes of runoff and achieve to predict flood areas, furthermore, were analyzed extreme hydrometeorological phenomena in the CBGM, by modeling the Hydrologic Modeling System (HEC-HMS) which is a SHM and the Modèle Hydrologique Simplifié à I'Extrême (MOHYSE) which is a GHM, to evaluate the results and compare which model is suitable for tropical conditions to propose public policies for integrated basins management and flood prevention. Thus it was determined the temporal and spatial framework of the analyzed basins according to hurricanes and floods. It were developed the SHM and GHM models, which were calibrated, validated and compared the results to identify the sensitivity to the real model. It was concluded that both models conform to tropical conditions of the CBGM, having MOHYSE further approximation to the real model. Worth mentioning that in Mexico there is not enough information, besides there are no records of MOHYSE use in Mexico, so it can be a useful tool for determining runoff volumes. Finally, with the SHM and the GHM were generated climate change scenarios to develop risk studies creating a risk map for urban planning, agro-hydrological and territorial organization.

Élaboration et réalisation d'un modèle d'analyse de situation

Depuis vingt ans, le monde de l'éducation du Québec en a vu de toutes les couleurs, en fait de changement. Le rapport Parent a remis en question les pratiques pédagogiques traditionnelles et autoritaires du monde de l'éducation. De là, toute une révolution s'est mise en marche. On a abandonné le passé avec ses traditions et ses valeurs, au nom du progrès et du développement; c'en fut fini de la stabilité et de la continuité. Tout a été bouleversé: bâtisses, structures, technologie, méthodes d'enseignement, règlements, discipline, etc. Cette révolution était nécessaire à cause de l'urgent rattrapage que l'éducation au Québec avait à faire. Mais, quelles conséquences ont eu ces changements sur les organisations scolaires et leur environnement? Que sont devenues les attentes, les attitudes et les aspirations de tous les intervenants face à l'école élémentaire? La publication du Livre Vert sur l'enseignement primaire et au secondaire à l'automne 1977 et la consultation qui s'en suivit ont permis au gouvernement du Québec de déceler les tendances et les aspirations de la collectivité en matière d'éducation primaire et secondaire. L'énoncé de politique et le plan d'action qui ont résulté à la consultation doivent être considérés comme un premier pas. Le deuxième pas se situe au niveau de chaque école avec le projet éducatif, tel que proposé au chapitre trois du document "École Québécoise". Ce deuxième pas, mandat ou "patate chaude" est apparu dernièrement è la table de gestion des principaux de la Commission scolaire et deux grandes questions sont apparues: "C'est quoi un projet éducatif?" et "Comment va-t-on s'y prendre pour arriver à en bâtir un dans nos écoles?". À la première question, il est possible d'y répondre avec la définition qu'en donne le livre orange (voir; définition de termes). Le problème apparaît à la deuxième question et, sur ce point, le M.E.Q. n'en dit pas long; il parle d'une démarche, une réflexion ou une remise en question. Il ne donne aucun moyen, sauf des documents à venir et un programme de soutien pour le développement de projet éducatif, aussi à venir. N'ayant pas encore trouvé de solution à la table de gestion, je ramène le problème au niveau de mon école et surtout au niveau de mon essai. Je tenterai donc de développer un moyen qui me permettra d'avoir un portrait de mon école à partir des intervenants cités dans la définition du P.E., portrait qui me permettra de voir les écarts entre la situation actuelle et la situation désirée chez chacun des intervenants et aussi préparer la prochaine étape qui est soulignée dans la définition d'un P.E., c'est-à-dire la concertation: action qui repose sur une préoccupationcommune de développement global des élèves.

Convergence Of Soil Nitrogen Isotopes Across Global Climate Gradients.

Quantifying global patterns of terrestrial nitrogen (N) cycling is central to predicting future patterns of primary productivity, carbon sequestration, nutrient fluxes to aquatic systems, and climate forcing. With limited direct measures of soil N cycling at the global scale, syntheses of the (15)N:(14)N ratio of soil organic matter across climate gradients provide key insights into understanding global patterns of N cycling. In synthesizing data from over 6000 soil samples, we show strong global relationships among soil N isotopes, mean annual temperature (MAT), mean annual precipitation (MAP), and the concentrations of organic carbon and clay in soil. In both hot ecosystems and dry ecosystems, soil organic matter was more enriched in (15)N than in corresponding cold ecosystems or wet ecosystems. Below a MAT of 9.8°C, soil δ(15)N was invariant with MAT. At the global scale, soil organic C concentrations also declined with increasing MAT and decreasing MAP. After standardizing for variation among mineral soils in soil C and clay concentrations, soil δ(15)N showed no consistent trends across global climate and latitudinal gradients. Our analyses could place new constraints on interpretations of patterns of ecosystem N cycling and global budgets of gaseous N loss.

Uso de perfis cromatográficos de voláteis de cafés arábicas torrados para a diferenciação das amostras segundo o sabor, o aroma e a qualidade global da bebida

In this work, the volatile chromatographic profiles of roasted Arabica coffees, previously analyzed for their sensorial attributes, were explored by principal component analysis. The volatile extraction technique used was the solid phase microextraction. The correlation optimized warping algorithm was used to align the gas chromatographic profiles. Fifty four compounds were found to be related to the sensorial attributes investigated. The volatiles pyrrole, 1-methyl-pyrrole, cyclopentanone, dihydro-2-methyl-3-furanone, furfural, 2-ethyl-5-methyl-pyrazine, 2-etenyl-n-methyl-pyrazine, 5-methyl-2-propionyl-furan compounds were important for the differentiation of coffee beverage according to the flavour, cleanliness and overall quality. Two figures of merit, sensitivity and specificity (or selectivity), were used to interpret the sensory attributes studied.

Previsões climáticas sazonais sobre o Brasil: avaliação do RegCM3 aninhado no modelo global CPTEC/COLA

Este trabalho avalia o desempenho de previsões sazonais do modelo climático regional RegCM3, aninhado ao modelo global CPTEC/COLA. As previsões com o RegCM3 utilizaram 60 km de resolução horizontal num domínio que inclui grande parte da América do Sul. As previsões do RegCM3 e CPTEC/COLA foram avaliadas utilizando as análises de chuva e temperatura do ar do Climate Prediction Center (CPC) e National Centers for Enviromental Prediction (NCEP), respectivamente. Entre maio de 2005 e julho de 2007, 27 previsões sazonais de chuva e temperatura do ar (exceto a temperatura do CPTEC/COLA, que possui 26 previsões) foram avaliadas em três regiões do Brasil: Nordeste (NDE), Sudeste (SDE) e Sul (SUL). As previsões do RegCM3 também foram comparadas com as climatologias das análises. De acordo com os índices estatísticos (bias, coeficiente de correlação, raiz quadrada do erro médio quadrático e coeficiente de eficiência), nas três regiões (NDE, SDE e SUL) a chuva sazonal prevista pelo RegCM3 é mais próxima da observada do que a prevista pelo CPTEC/COLA. Além disto, o RegCM3 também é melhor previsor da chuva sazonal do que da média das observações nas três regiões. Para temperatura, as previsões do RegCM3 são superiores às do CPTEC/COLA nas áreas NDE e SUL, enquanto o CPTEC/COLA é superior no SDE. Finalmente, as previsões de chuva e temperatura do RegCM3 são mais próximas das observações do que a climatologia observada. Estes resultados indicam o potencial de utilização do RegCM3 para previsão sazonal, que futuramente deverá ser explorado através de previsão por conjunto.

Fatores associados à prática de atividade física global e de lazer em idosos: Inquérito de Saúde no Estado de São Paulo (ISA-SP), Brasil

The purpose of this study was to measure the prevalence of global and leisure-time physical activity and associated factors in the elderly. This was a population-based cross-sectional study covering a multiple-stage sample of 1,950 subjects 60 years or older living in areas of São Paulo State, Brazil. Prevalence of global physical activity (assessed through the short version of the International Physical Activity Questionnaire - IPAQ) was 73.9%, and prevalence of leisure-time physical activity was 28.4%. The results highlight the differences between factors associated with global and leisure-time physical activities. The social groups most prone to overall sedentary lifestyle and especially to lack of leisure-time physical activity should be the main targets of health policies aimed at promoting healthier lifestyles.

Fatores associados à obesidade global e à obesidade abdominal em mulheres na pós-menopausa

OBJETIVOS: avaliar a prevalência de obesidade global e obesidade abdominal, em mulheres pós-menopausa, segundo o grau de instrução, nível de atividade física, uso de terapia hormonal na menopausa (THM) e paridade. MÉTODOS: foram entrevistadas 157 mulheres na pós-menopausa, atendidas em dois ambulatórios públicos da cidade de São Paulo, São Paulo, Brasil. A obesidade foi determinada segundo o índice de massa corporal (IMC > 30,0) e segundo o percentual de gordura corporal (%GC > 37%). A obesidade abdominal foi determinada pela relação cintura-quadril (RCQ > 0,85). RESULTADOS: a prevalência de obesidade global foi 34,4% (segundo o IMC) e de 40,1% (segundo o %GC). A prevalência de obesidade abdominal foi de 73,8%. Grande parte das entrevistadas referiu até sete anos de instrução formal (47,8%), foi considerada sedentária ou insuficientemente ativa (52,3%) e nunca tinha utilizado THM oral ou tinha utilizado por menos de 12 meses (72,0%). Foi constatada maior prevalência de obesidade global no grupo de mulheres sedentárias ou insuficientemente ativas e no grupo de não usuárias de THM (p<0,05). Quanto à obesidade abdominal, fator de risco para doenças cardiovasculares (DCV), apenas o grau de instrução mostrou-se associado à RCQ (p<0,05). CONCLUSÕES: mulheres após a menopausa, fisicamente ativas e usuárias de THM exibiram menor prevalência de obesidade global, porém a prevalência de obesidade abdominal foi alta e ainda maior nas mulheres com menor grau de instrução

Global gene expression under nitrogen starvation in Xylella fastidiosa: contribution of the sigma(54) regulon

Background: Xylella fastidiosa, a Gram-negative fastidious bacterium, grows in the xylem of several plants causing diseases such as citrus variegated chlorosis. As the xylem sap contains low concentrations of amino acids and other compounds, X. fastidiosa needs to cope with nitrogen limitation in its natural habitat. Results: In this work, we performed a whole-genome microarray analysis of the X. fastidiosa nitrogen starvation response. A time course experiment (2, 8 and 12 hours) of cultures grown in defined medium under nitrogen starvation revealed many differentially expressed genes, such as those related to transport, nitrogen assimilation, amino acid biosynthesis, transcriptional regulation, and many genes encoding hypothetical proteins. In addition, a decrease in the expression levels of many genes involved in carbon metabolism and energy generation pathways was also observed. Comparison of gene expression profiles between the wild type strain and the rpoN null mutant allowed the identification of genes directly or indirectly induced by nitrogen starvation in a sigma(54)-dependent manner. A more complete picture of the sigma(54) regulon was achieved by combining the transcriptome data with an in silico search for potential sigma(54)-dependent promoters, using a position weight matrix approach. One of these sigma(54)-predicted binding sites, located upstream of the glnA gene (encoding glutamine synthetase), was validated by primer extension assays, confirming that this gene has a sigma(54)-dependent promoter. Conclusions: Together, these results show that nitrogen starvation causes intense changes in the X. fastidiosa transcriptome and some of these differentially expressed genes belong to the sigma(54) regulon.

Global gene expression profile in myelodysplastic syndromes using SAGE

The molecular pathogenesis of myelodysplastic syndromes (MDS) is poorly understood. In order to expand our knowledge of genetic defects in MDS, we determined the overall profile of genes expressed in bone marrow from patients with refractory anemia with excess blasts ( RAEB) by serial analysis of gene expression ( SAGE). The present report describes a partial transcriptome of RAEB bone marrow derived from 56,694 sequenced tags that provides information about expressed gene products. This is the first attempt to determine an overall profile of gene expression specifically in RAEB at diagnosis using SAGE, which should be useful in the understanding of the physiopathology of MDS and in identifying the genes involved.
