Le "non-recours" à la Couverture maladie universelle : émergence d'une catégorie d'action et changement organisationnel / The "non take-up" of free health insurance coverage : emergence of a category of action and organisational change

Revil, Héléna 16 January 2014 (has links)
Cette thèse analyse l'émergence, en France, de la question du non-recours à la Couverture maladie universelle complémentaire (CMU C) et à l'Aide complémentaire santé (ACS), ainsi que son institutionnalisation dans la branche Maladie de la Sécurité sociale. La CMU C et l'ACS ont été créées pour limiter les inégalités d'accès aux soins. Celles-ci se sont en effet accrues avec les augmentations continues des frais de santé laissés à la charge des patients. Au croisement de la socio-histoire, de la sociologie de l'action publique et de la sociologie des organisations, le processus d'institutionnalisation du non-recours est étudié de manière chronologique, au travers de séquences d'action qui ont : initié une attention pour le phénomène ; positionné ses enjeux au regard des restructurations de la protection maladie des plus démunis ; construit des représentations et structuré une stratégie d'action pour le traiter. Principalement problématisé autour d'un enjeu d'effectivité des droits CMU C et ACS, le non-recours est devenu peu à peu un instrument opérationnel de la correction des inégalités d'accès aux soins, définie comme axe prioritaire de la gestion du risque maladie. Sa prise en compte a engagé l'Assurance maladie dans des changements profonds de pratiques et d'organisation du travail. De manière surplombante, c'est une transformation du rapport de l'institution à ses ressortissants fragiles qui s'est enclenchée, afin de faire en sorte que les populations démunies se rapprochent de leurs droits. En ce sens, l'institutionnalisation du non-recours s'inscrit dans un mouvement qui vise à concentrer les moyens et les actions de la branche Maladie sur les populations dites fragiles. Une approche de l'action publique par le non-recours aux droits paraît ainsi pertinente pour comprendre comment l'intégration de problèmes émergents, peu visibles ou volontairement ignorés, leur mise en sens par des acteurs publics et l'institution de nouvelles catégories d'action viennent travailler les organismes administratifs bureaucratiques dans leurs fonctionnements, leurs logiques et leurs normes d'intervention les plus ancrés. L'approche par le non recours est, en l'occurrence, un traceur du changement opéré à l'aune des ressortissants de l'action publique. / This thesis analyzes the emergence, in France, of the issue of non take-up of Free Supplementary Health Insurance Coverage (“Couverture maladie universelle complémentaire” or “CMU-C”) and Assistance for Private Health Insurance (“Aide complémentaire santé” or “ACS”), as well as its institutionalization within the Health branch of the Social Security system. The CMU-C and the ACS have been created to limit the inequalities in access to healthcare. These have indeed risen with the continuous increase of health expenses left payable by the patients. At the crossroads of socio-history, sociology of public action and sociology of organizations, the process of institutionalization of non take-up is studied chronologically, through sequences of action which have: brought to attention the phenomenon; positioned its challenges in light of the health care restructurings for the most destitute; built representations and structured a plan of action to treat it. Problematized primarily around the challenge of operativity of the CMU-C and ACS benefits, the non take-up has gradually become an operational tool for the correction of inequalities in access to healthcare, which was defined as a priority in the management of health issues. Addressing it has committed the health system to profound changes in its practices and work organization. Overarching it, a transformation of the institution's relationship to its vulnerable nationals has been set into motion, to ensure that the destitute populations are brought closer to their benefits. In this respect, the institutionalization of non take-up is part of a movement that seeks to concentrate the resources and actions of the Health branch on the populations considered vulnerable. An approach of public action by the non take-up of benefits thus appears relevant for understanding how the integration of emerging problems, less visible or deliberately ignored, their sensegiving by public actors and the institution of new categories of action, come to challenge the bureaucratic administrations in their most entrenched functioning, logic and standards of intervention. The approach by the non take-up is, as it happens, an indicator of change operated with regard to public action beneficiaries.

Utvärdering av Velanders formel för toppeffektberäkning i eldistributionsnät : Regressionsanalys av timvis historiska kunddata för framtagning av Velanderkonstanter

Persson, Erik, Jonsson, Patrik January 2018 (has links)
Toppeffekter används av elnätsbolag för att dimensionera elnätet, vilket blir allt viktigare för varje år. Fler och fler invånare och företag ökar sin elkonsumtion och förväntar sig en driftsäker och stabil elförsörjning. Det finns två vanliga metoder att beräkna toppeffekter. Första sättet är Velanders formel som är en enkel metod för att uppskatta toppeffekter. Velanders formel behöver bara årsenergi och vetskap om kundkategori med tillhörande Velanderkonstanter för beräkning av uppskattad toppeffekt. Sedan finns den mer komplexa typkurvemetoden som behöver flera olika parametrar, t.ex. graddagtal, dygnsmedeltemperatur, gränssannolikhet och kundkategori. Detta examensarbete undersöker en enkel metod för att ta fram konstanter till Velanders formel för beräkning av toppeffekter. Detta genomfördes med hjälp av regressionsanalys av historiska elanvändningsdata från Mälarenergi Elnät AB:s (MEE) kunder från 12 olika kundkategorier. Detta på grund av att MEE önskade att utveckla en metod för att ta fram konstanter till Velanders formel baserad på historiska elanvändningsdata. Metoden för att ta fram konstanter till Velanders formel går ut på att med hjälp av MATLAB utföra en regressionsanalys på simulerade kundgrupper skapade från timvis historiska elanvändningsdata. En kurva baserad på Velanders formel tas sedan fram som beskriver den övre gränsen till toppeffekterna för de simulerade kundgrupperna. Från kurvan fås sedan de Velanderkonstanter som söks. Resultaten av den undersökta metoden presenteras i form av grafer och tabeller för tre utvalda kundkategorier. Alla kategorier och deras resultat finns som bilagor till rapporten. Valideringen av resultaten och metoden gjordes med hjälp av korsvalidering och jämförelse mot heterogena simulerade kundgrupper. Känslighetsanalysen visar att den undersökta metoden var känslig för flera faktorer såsom kategorisering av kunder, tidsspann för historiska elanvändningsdata, antal simulerade kundgrupper och kundantal. Med tillräcklig dimensionering av dessa faktorer bedömdes metoden vara användbar. Resultaten visade på att de framtagna Velanderkonstanterna gav en god uppskattning av toppeffekter för de kundkategorier som undersökts. Jämförelse av de uppskattade toppeffekterna och de observerade visade på att det fanns en viss differens mellan dem. Detta var dock förväntat eftersom de uppskattade toppeffekterna ska avspegla den övre toppeffektsgränsen. / This degree project has examined a simple method aiming to obtain coefficients for Velanders formula which purpose is to calculate peak loads. This was done by using regression analysis on historical data on consumption of electricity from 12 different customer categories acquired from Mälarenergi Elnät AB (MEE). The reason being that MEE wanted to examine a method which could obtain coefficients for Velanders formula based on hourly historical electricity consumption data. The method for obtaining Velander coefficients uses MATLAB to do regression analysis on simulated customer groups, created from hourly historical electricity consumption data. The Velander coefficients are then obtained from a regression curve based on Velanders formula. Results from the evaluation of the method is presented with the help of plots and tables for three chosen customer categories. Validation of the method was done by cross-validation and comparison against heterogeneous customer groups. Sensitivity analysis showed the examined method to be sensitive to several factors such as categorization of customers, the timespan of historical electricity consumption data, the number of simulated customer groups that were used and how many customers a category contained. By dimensioning these factors carefully, the method examined was assessed to be viable. The results indicated that the obtained Velander coefficients gave a good estimation of the peak loads for the chosen customer categories. Comparison between the estimated and observed peak loads indicated that there was a certain difference between them. This was to be expected since the estimated peak loads are to reflect the upper peak load limit.

The Juridical Act as a historiography category / El Negocio Jurídico como categoría historiográfica

Irti, Natalino 12 April 2018 (has links)
This article addresses the issue of the pre-legal nature of the Juridical and its stratification in the social and legal level. Also, it contrasts the theory of the will and the theory of the declaration, and refers to the controversy between Emilio Betti and Giuseppe Stolfi about the dispute over the language. The idea of monism is developed in the theory of the Juridical Act quoting Santi Romano and Hans Kelsen, as well as its tensions with dualism. Finally, it takes Juridical Act as historiographical category, and its relationship to the problems of technological society and closes with the gap between private autonomy and Juridical Act. / El presente artículo aborda la cuestión de la naturaleza prejurídica del negocio jurídico, así como su estratificación en el plano social y jurídico. Asimismo, se contrapone la teoría de la voluntad y la teoría de la declaración, y se remite a la polémica entre Emilio Betti y Giuseppe Stolfi como disputa sobre el lenguaje. Se desarrolla la idea del monismo en la teoría del negocio jurídico citando a Santi Romano y Hans Kelsen, así como sus tensiones con el dualismo. Finalmente, se trata al negocio jurídico como categoría historiográfica, y su relación con los problemas de la sociedad tecnológica para cerrar con la separación entre autonomía privada y negocio jurídico.

Aproximación a la imagen real de "los incas de privilegio"

Someda, Hidefuji 10 April 2018 (has links)
Approach to the True Image of the "Incas by Privilege"This study aims at clarifying the identity of one special social category in the Inca state, "the Incas by privilege". Historians and cultural anthropologists have argued that the Incas by privilege played a part in the maintenance of domination by the Incas, but they do not explain the reason(s) for the existence of this category of people. This is due to the scarcity and ambiguity of information about them in the historical documents. However, in order to clarify the historical processes of the territorial expansion of the Inca state, it is essential to advance research on the social and political function of the Incas by privilege. This study undertakes such an analysis by discussing some of the central characteristics of this group of people as they are described and characterized in the chronicles. / El presente trabajo trata de aclarar la imagen de una categoría social en el Estado incaico, llamada "incas de privilegio", analizando principalmente las crónicas indígenas. Es claro que casi todos los historiadores o etnohistoriadores coinciden en afirmar que los incas de privilegio desempeñaban algún papel en el mantenimiento de la dominación del Estado incaico, pero no precisan su razón de ser en dicho Estado. Naturalmente, eso se debe principalmente a la falta de noticias sobre ellos en los documentos o crónicas, y a que la mayoría de estas pocas noticias son muy vagas. Pero, para aclarar mucho más la realidad histórica de la expansión del dominio del Estado incaico en los Andes, es innegable e indispensable desarrollar la investigación sobre la función social y política de los incas de privilegio. En este trabajo, por ello, se pretende demostrar sus características a través del análisis de las crónicas y a manera de ensayo, con la esperanza de que su estudio sea profundizado por los arqueólogos y los antropólogos.

Teorias de 2-gauge e o invariante de Yetter na construção de modelos com ordem topológica em 3-dimensões / 2-gauge theories and the Yetter\'s invariant on the construction of models with topological order in 3-dimensions

Hudson Kazuo Teramoto Mendonça 29 June 2017 (has links)
Ordem topológica descreve fases da matéria que não são caracterizadas apenas pelo esquema de quebra de simetria de Landau. Em 2-dimensões ordem topológica é caracterizada, entre outras propriedades, pela existência de uma degenerescência do estado fundamental que é robusta sobre perturbações locais arbitrarias. Com o proposito de entender o que caracteriza e classifica ordem topológica 3-dimensional o presente trabalho apresenta um modelo quântico exatamente solúvel em 3-dimensões que generaliza os modelos em 2-dimensões baseados em teorias de gauge. No modelo proposto o grupo de gauge é substituído por um 2-grupo. A Hamiltonia, que é dada por uma soma de operadores locais, é livre de frustrações. Provamos que a degenerescência do estado fundamental nesse modelo é dado pelo invariante de Yetter da variedade 4-dimensional Sigma × S¹, onde Sigma é a variedade 3-dimensional onde o modelo está definido. / Topological order describes phases of matter that cannot be described only by the symmetry breaking theory of Landau. In 2-dimensions topological order is characterized, among other properties, by the presence of a ground state degeneracy that is robust to arbitrary local perturbations. With the purpose of understanding what characterizes and classify 3-dimensional topological order this works presents an exactly soluble quantum model in 3-dimensions that generalize 2-dimensional models constructed using gauge theories. In the model we propose the gauge group is replaced by a 2-group. The Hamiltonian, that is given by a sum of local commuting operators, is frustration free. We prove that the ground state degeneracy of this model is given by the Yetters invariant of the 4-dimensional manifold Sigma × S¹, where Sigma is the 3-dimensional manifold the model is defined.

Sistemas de classificação do conhecimento na filosofia e na biblioteconomia: uma visão histórico-conceitual crítica com enfoque nos conceitos de classe, de categoria e de faceta / Sistemas de classificação do conhecimento na filosofia e na biblioteconomia: uma visão histórico-conceitual crítica com enfoque nos conceitos de classe, de categoria e de faceta

Liane dos Anjos 02 March 2009 (has links)
A análise dos sistemas de classificação do conhecimento na Filosofia e na Biblioteconomia sob um ponto de vista histórico-conceitual crítico com enfoque nos conceitos de classe, categoria e faceta foi desenvolvida a partir dos objetivos específicos de acompanhar e delinear a trajetória das classificações dos saberes (classes) e dos seres (categorias) à luz da Filosofia; averiguar as possíveis influências que as classificações filosóficas historicamente exerceram sobre as classificações bibliográficas tradicionais; e verificar de que modo os conceitos específicos de categoria, de classe e de faceta têm sido definidos no âmbito das classificações biblioteconômicas tradicionais. Trata-se de uma pesquisa do tipo exploratório-descritivo, embasada na literatura pertinente, oriunda de ambas as áreas do conhecimento em questão. A partir do levantamento bibliográfico construiu-se o referencial teórico, conduzindo à objetivação, análise, discussão e o aprofundamento do objeto. É possível afirmar que tanto os princípios das classificações filosóficas em relação aos saberes e em relação aos seres, quanto as próprias classificações que dividem os saberes e os seres, apresentam-se como construtos destinados a conhecer e disciplinar o conhecimento do ser e do saber. A influência das classificações filosóficas sobre as classificações bibliográficas reside no fato de que as classificações bibliográficas são adaptações das classificações do conhecimento ou das ciências. As bibliográficas, frequentemente, utilizam termos originários das filosóficas, ressignificando-os e transformando-os em ferramentas. Em síntese, pode-se afirmar que, a partir da Filosofia, absorvida em explicações teóricas, até a Biblioteconomia, preocupada com soluções instrumentais e aplicativas (pragmáticas), os esquemas de classificação bibliográfica propostos tem se beneficiado da aproximação dessas duas áreas de conhecimento. A revisão conceitual com respeito às noções de classe, categoria e faceta aponta, por parte dos estudiosos da Classificação, para a necessidade de um cuidado maior no desenho, no planejamento e na estruturação de sistemas de classificação, na modificação e especificação de tabelas de classificação e até de linguagens de indexação, com vista à sua adequação e relevância. As contribuições daí resultantes, delineadas numa perspectiva funcional-instrumental, poderão ajudar os profissionais a reconsiderar os seus sistemas de idéias e procedimentos em relação à construção e avaliação de linguagens de indexação e à classificação habitual de documentos. Caberá à Ciência da Informação avançar na fundamentação teórica do seu campo de aplicação, discutindo criticamente a sua base conceitual, atenta às práticas de uso em voga na Biblioteconomia e Documentação com relação a termos e conceitos. O estudo valida as hipóteses inicialmente levantadas, determinando que a consistência terminológica de termos como categoria, classe ou faceta contribui para aperfeiçoar a operacionalização do processamento do conhecimento em Ciência da Informação e que aos esquemas categoriais não cabe um valor neutro, uma vez que sempre favoreceram uma determinada concepção de mundo, em que pese a sua natureza objetivamente pragmática. Por fim, apresentam-se algumas perspectivas decorrentes da investigação, selecionando-se questões relevantes e de interesse para futuras pesquisas. / The analysis of knowledge classification systems in Philosophy and Librarianship by a critical historical-conceptual point of view with an approach in the concepts of class, category and facet was developed from specific objectives to accompany and outline the path of knowledge (classes) and beings (categories) classification in relation to Philosophy; to investigate the possible influences that the philosophical classification historically exerted on traditional bibliographical classifications; and to verify in which way the specific concept of category, class and facet have been defined in the ambit of traditional librarianship classifications. This research is of exploratory-descriptive type, based upon pertinent literature, resulting from both areas of knowledge in discussion. From the studied bibliographical material, a theoretical reference was built, leading to objectivation, analysis, discussion and a profound study of the object. Its possible to affirm that even the principles of philosophical classifications in relation to knowledge and beings, as well as the classifications that divide knowledge and beings, are presented as constructs, purposed to understand and to train the information of beings and knowledge. The influence of philosophical classifications on bibliographical classification is settled by bibliographical classifications, which are adaptations of knowledge or science. The bibliographical ones, frequently utilize terms originated from philosophical that are modified and transformed into tools. In synthesis, it may be stated that, from Philosophy, absorbed in theoretical explanations, even Librarianship, worried with instrumental and application (pragmatic) solutions, the proposed plans of bibliographical classifications have been beneficiated from the approximation of this two areas of knowledge. The conceptual review in relation to notions of class, category and facet needs a better attention in design, planning and in the structuring of classification systems, as pointed out by experts on Classification, in the modification and specification of classification tables and also indexation languages, aiming its adequacy and significance. The resulting contributions, outlined by a functional-instrumental perspective, would help professionals to reconsider their systems of ideas and procedures in relation to construction and evaluation of indexation languages and regular classification of documents. The information science will be responsible to develop theory fundamentation of its application field, discussing critically its conceptual basis, with attention to the practices in use by Librarianship and Documentation in relation to terms and concepts. The study validates the hypothesis initially described, determining that the terminological consistency of terms as category, class or facet contribute to improve the operacionalization of knowledge processing in Information Science and that to category schemes it doesnt fit a neuter value, since that always favored a certain conception of the world, in which predominates its pragmatic nature As result of the investigation, some perspectives are presented, selecting questions of extreme relevancy and interest for future researches.

Positive solutions for Schrödinger-Poisson type systems / Soluções positivas para sistemas do tipo Schrödinger-Poisson

Edwin Gonzalo Murcia Rodriguez 09 June 2017 (has links)
In this thesis we study Schrödinger-Poisson systems and we look for positive solutions. Our work consists in three chapters. Chapter 1 includes some basic facts on critical point theory. In Chapter 2 we consider a fractional Schrödinger-Poisson system in the whole space R^N in presence of a positive potential and depending on a small positive parameter . We show that, for suitably small (i.e. in the \"semiclassical limit\") the number of positive solutions is estimated below by the Ljusternick-Schnirelmann category of the set of minima of the potential. Finally, in Chapter 3, we analyze a Schrödinger-Poisson system in R^3 under an asymptotically cubic nonlinearity. We prove the existence of positive, radial solutions inside a ball and in an exterior domain. / Nesta tese nós estudamos sistemas de Schrödinger-Poisson e procuramos soluções positivas. Nosso trabalho consiste em três capítulos. O Capítulo 1 contém alguns fatos básicos sobre a teoria de pontos críticos. No Capítulo 2 nós consideramos um sistema fracionário de Schrödinger-Poisson em todo o espaço R^N em presença de um potencial positivo e que depende de um pequeno parâmetro positivo . Nós mostramos que, para suficentemente pequeno (i.e. no limite semiclássico) o número de soluções positivas é estimado por abaixo pela categoria de Ljusternick-Schnirelmann dos conjuntos onde o potencial é mínimo. Finalmente, no Capítulo 3 nós analisamos um sistema Schrödinger-Poisson em R^3 sob a não linearidade assintoticamente cúbica. Mostramos a existência de soluções radiais positivas dentro de uma bola e em um domínio exterior.
