Políticas públicas, judiciário e saúde: limites, excessos e remédios / Public policies, judiciary and public health: limits, excesses and remedies

Sabino, Marco Antonio da Costa 22 April 2014 (has links)
Trata-se o presente de estudo analítico e propositivo que circunda em torno do tema do controle jurisdicional de políticas públicas, com destacado vigor no que toca às prestações e ações de saúde a cargo do Poder Público. Analisando o fenômeno da assunção do Judiciário como arena de debate político e atribuição de direitos, ver-se-á que há virtudes e vicissitudes nesse que é caminho irreversível da sociedade moderna. No campo da intervenção judicial na saúde, serão demonstrados os grandes transtornos gerados por uma atividade pouco cautelosa e ainda predominantemente fundada nas premissas processuais do Século XIX, o que gera um desarranjo de contas e estratégias e deflagra uma clara crise entre os Poderes instituídos. Ademais, do modo como sucede hoje, a intervenção judicial em políticas de saúde acaba privilegiando poucos à custa de muitos, quando a saúde é taxativamente direito que deve ser atribuído pelo Estado de maneira isonômica e universal. A partir do diagnóstico das patologias causadas pela desmedida intervenção judicial na saúde, realizada a partir de pesquisa empírica e revisão bibliográfica, esta tese estabelecerá limites que deverão ser observados pelo magistrado, verdadeiras fronteiras que, caso ultrapassadas, agravarão e perpetuarão o problema. Ato contínuo, serão propostas medidas que se prestam a tornar o exercício da judicatura nessa seara mais harmônico com a própria gênese do direito à saúde. A ideia, assim, é auxiliar magistrados e operadores a tornar a tarefa de sindicar ações e prestações estatais de saúde mais racional, equilibrada, justa e universal, mediante propositura de limites e adoção de instrumentos apropriados, processuais e não processuais. / This work derives from a research upon Brazilian judicial intervention in public policies, focusing in how this intervention works regarding the constitutional duty, drove to the State, of providing health to people. Analyzing the political phenomena of Judiciary as one of the most relevant public discussions arena, this thesis will show that virtues and inconveniences arise from this Brazilian modern society reality. Considering judicial intervention upon public health, the work will explore the great problems issued by a less cautious activity founded in relevant part on classic procedural premises of the 19th Century, which causes public accountancy disruption and overwhelms administrative strategies, generating a clear crisis amid instituted Powers. Moreover, as it flows nowadays, judicial intervention upon health public politics privileges few against interests of many, as health is a right of everyone and as indeclinable duty of State under the expression rule of Brazilian Constitution. After diagnose the pathologies caused by immeasurable judicial intervention upon public health, featured both by empirical research and bibliographic revision, this thesis will establish boundaries that might be observed by judges when accomplishing their honorable task, limits that, once overtook, make the problem worst and permanent. Afterwards, some measures will be proposed in order to turn judicial activity in this specific field more harmonic with proper nature of right to health. Hence, the main idea is to help judges and other agents to turn the judicial task of intervention in public health more rational, balanced, fair and universal by proposing limits and adopting appropriated procedural and no procedural instruments.

No. of bitstreams: 1 DoutZJS.pdf: 1318890 bytes, checksum: 8af8fb950a57d0d932f8e30174091a58 (MD5) Previous issue date: 2003-12-18 / Given the estimated potential of electric energy generation around 18 thousand MW and the necessity to expand and diversify the installed national capacity of energy generation, this dissertation investigates the reasons for the low performance in the exploitation of the investment opportunities in electric energy commercialization by the sugarcane sector. With this purpose, the research presents a diagnosis of the main structural obstacles and transaction costs present in the generation of electric energy surpluses, showing the importance of the institutions in the decision of expansion of the activity by the sugarcane sector. The results were contrasted with the proposal of governmental energy policy for incentive this activity. It was verified the necessity of improvement in the current institutional environment. The main contribution of the dissertation was to present directives to public policies. These directives focus the financing for the expansion of the activity; the commercialization of the excesses; the tax incentive; and the concession of direct subsidies to the expansion of the activity. The directives related to financing were: official lines differentiated by technology use, index of mechanization and scale; the Ethical Fund Formation for the sector; and projects finance involving Emissions Reduction Certificate. Regarding commercialization, directives were: subvention to the transport tariffs; the extension of the universe of potentially free consumers; formation of trading pools and inclusion in the Energy Replacement Mechanism; the insertion of the sugarcane energy in the composition of Factor X and in the National Energy Reserve; changes in the retailers' auto-supplement; and incentive to the commercialization of energy surpluses and of Emissions Reduction Certificates. Directives related to tax incentive were also presented. Regarding direct subsidies, it is interesting the use of the resources that come from the Use of Public Good and Fuel Consume Account to foster the expansion of the energy surpluses commercialization. / Considerando um potencial estimado de geração de energia elétrica da ordem de 18 mil MW e a necessidade de expandir a capacidade nacional instalada de geração, bem como, de diversificá-la, a tese investigou os motivos para o baixo desempenho no aproveitamento das oportunidades de investimento presentes na geração de excedentes comercializáveis de energia elétrica pelo setor sucroalcooleiro. Para tanto, a pesquisa apresenta um diagnóstico dos principais entraves estruturais e custos de transação presentes na atividade de geração de excedentes de energia elétrica, mostrando a importância das instituições na decisão de expansão da atividade pelo setor sucroalcooleiro. Os resultados obtidos foram confrontados com a proposta de política setorial governamental para incentivo à atividade em pesquisa. Verificou-se a necessidade de aprimoramento do Ambiente Institucional proposto, conforme estipulado na hipótese central do trabalho. As diretrizes para políticas setoriais governamentais, propostas por esta tese, enfocam o financiamento à expansão da atividade; a comercialização dos excedentes; o incentivo tributário; e a concessão de subsídios diretos à expansão da atividade. Especificamente, as diretrizes apresentadas quanto ao aspecto de financiamento foram: linhas oficiais diferenciadas por tecnologia empregada, por índice de mecanização e por porte de empresa; a Formação de Fundo Ético para o setor; e projects finance envolvendo Certificados de Redução de Emissões. No enfoque da comercialização, as diretrizes foram: subvenção às tarifas de transporte; a extensão do universo de consumidores potencialmente livres; a formação de um pool de usinas sucroalcooleiras e inclusão no Mecanismo de Realocação de Energia; a inserção da energia sucroalcooleira na composição do Fator X e na Reserva Nacional de Energia; alterações na questão do auto-suprimento das distribuidoras; e o incentivo à comercialização de excedentes de energia e de Certificados de Redução de Emissões. Foram também apresentadas diretrizes quanto ao incentivo tributário à atividade. Com relação ao aspecto de subsídios diretos, as diretrizes apresentadas abordam a utilização dos recursos advindos do Uso do Bem Público e da Conta de Consumo de Combustíveis para estímulo à expansão da atividade de comercialização de excedentes.

Mélanges bayésiens de modèles d'extrêmes multivariés : application à la prédétermination régionale des crues avec données incomplètes / Bayesian model mergings for multivariate extremes : application to regional predetermination of floods with incomplete data

Sabourin, Anne 24 September 2013 (has links)
La théorie statistique univariée des valeurs extrêmes se généralise au cas multivarié mais l'absence d'un cadre paramétrique naturel complique l'inférence de la loi jointe des extrêmes. Les marges d'erreur associée aux estimateurs non paramétriques de la structure de dépendance sont difficilement accessibles à partir de la dimension trois. Cependant, quantifier l'incertitude est d'autant plus important pour les applications que le problème de la rareté des données extrêmes est récurrent, en particulier en hydrologie. L'objet de cette thèse est de développer des modèles de dépendance entre extrêmes, dans un cadre bayésien permettant de représenter l'incertitude. Le chapitre 2 explore les propriétés des modèles obtenus en combinant des modèles paramétriques existants, par mélange bayésien (Bayesian Model Averaging BMA). Un modèle semi-paramétrique de mélange de Dirichlet est étudié au chapitre suivant : une nouvelle paramétrisation est introduite afin de s'affranchir d'une contrainte de moments caractéristique de la structure de dépendance et de faciliter l'échantillonnage de la loi à posteriori. Le chapitre 4 est motivé par une application hydrologique : il s'agit d'estimer la structure de dépendance spatiale des crues extrêmes dans la région cévenole des Gardons en utilisant des données historiques enregistrées en quatre points. Les données anciennes augmentent la taille de l'échantillon mais beaucoup de ces données sont censurées. Une méthode d'augmentation de données est introduite, dans le cadre du mélange de Dirichlet, palliant l'absence d'expression explicite de la vraisemblance censurée. Les conclusions et perspectives sont discutées au chapitre 5 / Uni-variate extreme value theory extends to the multivariate case but the absence of a natural parametric framework for the joint distribution of extremes complexifies inferential matters. Available non parametric estimators of the dependence structure do not come with tractable uncertainty intervals for problems of dimension greater than three. However, uncertainty estimation is all the more important for applied purposes that data scarcity is a recurrent issue, particularly in the field of hydrology. The purpose of this thesis is to develop modeling tools for the dependence structure between extremes, in a Bayesian framework that allows uncertainty assessment. Chapter 2 explores the properties of the model obtained by combining existing ones, in a Bayesian Model Averaging framework. A semi-parametric Dirichlet mixture model is studied next : a new parametrization is introduced, in order to relax a moments constraint which characterizes the dependence structure. The re-parametrization significantly improves convergence and mixing properties of the reversible-jump algorithm used to sample the posterior. The last chapter is motivated by an hydrological application, which consists in estimating the dependence structure of floods recorded at four neighboring stations, in the ‘Gardons’ region, southern France, using historical data. The latter increase the sample size but most of them are censored. The lack of explicit expression for the likelihood in the Dirichlet mixture model is handled by using a data augmentation framework

L’enfant et la liberté religieuse à la lumière du droit international, européen et français / Child and Religious Freedom in the Light of International, European and French Law

Meddour, Sabrina 15 December 2011 (has links)
Le droit à la liberté de pensée, de conscience et de religion expressément reconnu à l’enfant par l’article 14 de la Convention internationale de New York adoptée en 1989 soulève de nombreuses questions. En raison de l’état de dépendance de l’enfant et de sa vulnérabilité, l’exercice de cette liberté apparaît particulièrement fragilisée. Les droits de l’enfant sont en effet menacés de toute part, tant par l’autorité publique, que par sa famille, ou par des tiers, voire par l’enfant lui-même. Les parents tout en étant les premiers protecteurs et les premiers « guides spirituels » de l’enfant pourront parallèlement représenter les premiers obstacles à l’exercice de sa liberté religieuse pleine et entière suscitant un conflit entre droits parentaux et droits de l’enfant. L’État s’érige d’ailleurs en protecteur lorsque ses parents lui font courir un risque au nom même de leurs convictions religieuses. Le juge pourra aussi connaître de conflits familiaux provoqués par un désaccord religieux. Garant de l’ordre public, l’État sera parfois amené à limiter la liberté religieuse de l’enfant et de ses parents en mettant en avant la primauté d’un intérêt social tel la sauvegarde du principe de laïcité. Il apparaît donc nécessaire de considérer la question de la liberté religieuse de l’enfant à la fois dans la sphère familiale et plus largement dans la société en nous interrogeant notamment quant à l’effectivité réelle du droit de liberté religieuse de l’enfant. Comme pour tout sujet touchant aux droits de l’enfant, la recherche de l’équilibre entre liberté et protection s’inscrit sur un chemin difficile dont témoigne l’étude du droit de l’enfant à la liberté religieuse. / The right to freedom of thought, conscience and religion expressly granted to the child under article 14 of the Convention on the Rights of the Child adopted in 1989 raises many questions. Regarding his particular dependence and vulnerability, the exercise of this liberty by the child appears particularly weaken. Children’s rights are indeed threatened from all quarters, so much by public authority as by their family or by third parties, if not by the child himself. Parents, while being his first protectors and first “spiritual guides”, can also represent the first obstacle to the full exercise of the child’s freedom of religion, therefore raising a conflict between parental and children’s rights. It is to be noticed that the State establishes itselfs as the protector of the child whenever parents endanger him even in the name of religious beliefs. The judge might also intervene within family conflicts resulting from religious disagreements. Ensuring public order as well, the State will in some cases subject child’s and parents’ freedom of religion to limitations deemed necessary in regard to the primacy of a particular social interest such as the protection of secularism. It seems therefore essential to consider the question of the child’s religious freedom within the family sphere as well as, to a larger extent, within society, while questioning the effectivity of the right of the child to religious freedom. As for any subject relating to children’s rights, the search for balance between freedom and protection is engaged on a difficult path as evidenced by this study on the right of the child to religious freedom.
