This concept will be characterized as the singular way of being of the man, named in the context of Being and time, Dasein. Thus, we address the issue in four stages. At first, we present a brief exposition of Heidegger s ontological project, necessary for a correct understanding of all this work. At this time, should be highlighted why Dasein figure as the privileged being and, thus, thematized throughout the book. In the second phase, the theme being developed is the existence as a new way of understanding the entity that exists always in relation with being. Since, in Being and time, Heidegger abandons the older categories that only apply to entities other than ourselves, and forge the existential expression to refer to the characteristics of Dasein. In the third step we will address the opening of existence as the place where the manifestation of being is given, as will e shown that the decay is the instance that characterizes the improper existence, but through the anguish it can choose to be at their own since it do not run away to be faced with their true condition. Finally, at the last moment of our thesis, the aim is to explain how the phenomenon of death and conscience allow the fundamental openness of Dasein to its own existence. / O presente trabalho aborda o conceito de existência, apresentado na obra capital de Martin Heidegger, Ser e tempo. Este conceito será caracterizado como o modo de ser singular do homem, chamado, no contexto de Ser e tempo, Dasein. Desse modo, abordamos o tema em quatro momentos. No primeiro momento, apresentamos uma breve exposição do projeto ontológico heideggeriano, necessária para uma correta compreensão do todo deste trabalho. Neste primeiro momento, deverá ser destacado o porquê de o Dasein figurar como o ente privilegiado e, portanto, tematizado ao longo da obra. No segundo momento, o tema a ser desenvolvido é a existência como um novo modo de compreender o ente que existe sempre em relação com o ser. Uma vez que, em Ser e tempo, Heidegger abandona as velhas categorias aplicáveis apenas aos entes que não somos nós mesmos, e forja a expressão existencial para se referir as características próprias do Dasein. No terceiro momento abordaremos a abertura da existência como lugar onde se dá a manifestação do ser, assim como será mostrado que a decadência é a instância que caracteriza a existência imprópria, contudo através da angústia ele pode escolher existir de modo próprio desde que não fuja ao se ver diante de sua verdadeira condição. Por fim, no último momento de nossa dissertação, a meta é explicitar como os fenômenos da morte e da consciência possibilitam a abertura fundamental do Dasein para a existência própria.

Problem that Sartre and became the maximum of existentialism where the existence precedes the essence. We`ll try, in the course of our work, presenting the arguments used by Sartre that justify such affirmation and check if, in fact, it is possible to agree with an existential philosophy along the sartrianos lines. For that, we`ll see the phenomenological method that will assist us in the reflection on the fundamental structures of mundane appearance, central theme present in the husserliana phenomenology and sartriana`s foundation. This appearance will reveal the human reality as emanating from the most intimate of be; this human reality will be described in phenomenological philosophy of Sartre as consciousness, which conceptualizes as intentionality. Being intentionality is to take the constant motion of transcendence, that is, the exit of yourself. So it is necessary to expel everything there is or inhabits the consciousness. Making empty consciousness or translucent, requires that we understand the consciousness. Being conscious is to exist and the question of existence arises immediately with the human reality that asks about your way of being in the world. We will approach the existential problems of consciousness and the need for recognition of the same existence from reflexivity. In this way, we will develop how consciousness exists immediately, this is, how the consciousness appears intended to the objects of the world, how if seizes, first as a way thoughtless as a phenomenon of world. This mundane phenomenon that reveals the consciousness and is, at the same time, revealed by it. In this way, the appearances of world and consciousness occur simultaneously and interdependent. This concurrency between world and consciousness are the poles of the same phenomenon. It is the monism of the phenomenon that is constituted of these two realities of being, that is, the object appeared the In-himself and the consciousness - the To-himself - are constituent parts of the same reality that cannot be seized separately. The existence, although unique, is paradoxically, constituted of two modalities of being. Despite having to recognize these two modalities to be as amalgamated, we can only recognize them from a long journey argumentative of phenomenological reflection, once we can only recognize the existence of the world and consciousness from the phenomenological process of reflexivity. In other words, we can only know what already exists since the knowledge doesn´t have itself the creative force or the power to confer being what is not yet or does not exist. Thus, the knowledge or the reflection are fundamental to the development of phenomenology, although this same phenomenology requires the recognition of something prior or immediate that precedes it and enables your cognitive achievement. / O problema que nos motivou na elaboração desse trabalho foi responder à questão: como ocorre o aparecimento do mundo e como se torna consciente de tal aparecimento? Problema posto por Sartre e que se tornou a máxima do existencialismo onde a existência precede a essência. Intentaremos, no curso de nosso trabalho, apresentar os argumentos utilizados por Sartre que justificam tal afirmação e verificar se, de fato, é possível concordar com uma filosofia existencial nos moldes sartrianos. Para tanto, valer-nos-emos do método fenomenológico, que nos auxiliará na reflexão sobre as estruturas fundamentais do aparecimento mundano, tema central presente na fenomenologia husserliana e alicerce da sartriana. Tal aparecimento revelará a realidade humana como emanada do mais íntimo do ser; essa realidade humana será descrita na filosofia fenomenológica de Sartre como consciência, que se conceitua como intencionalidade. Ser intencionalidade é assumir o constante movimento de transcendência, isto é, de saída de si. Por isso, faz-se necessário que se expulse tudo o que há ou habita a consciência. Tornando a consciência vazia ou translúcida, exige-se que nós compreendamos a consciência. Ser consciente é existir e a questão da existência surge imediatamente com a realidade humana que indaga sobre seu modo de ser no mundo. Abordaremos a problemática existencial da consciência e a necessidade do reconhecimento dessa mesma existência a partir da reflexividade. Desse modo, apresentaremos como a consciência existe imediatamente, isto é, como a consciência aparece intencionada aos objetos do mundo, como se apreende, primeiramente de modo irrefletido como um fenômeno do mundo. Esse fenômeno mundano que revela a consciência e é, ao mesmo tempo, revelado por ela. Assim, os aparecimentos do mundo e da consciência ocorrem de modo simultâneo e interdependente. Essa simultaneidade entre mundo e consciência são polos de um mesmo fenômeno. É o monismo do fenômeno que se constitui dessas duas realidades do ser, ou seja, o objeto aparecido o Em-si e a consciência o Para-si são partes constituintes de uma mesma realidade que não podem ser apreendidas isoladamente. A existência, apesar de única, é paradoxalmente, constituída de duas modalidades de ser. Apesar de ter de reconhecer essas duas modalidades de ser como amalgamadas, só podemos reconhecê-las a partir de um longo percurso argumentativo da reflexão fenomenológica, pois só podemos reconhecer a existência do mundo e da consciência a partir do processo fenomenológico da reflexividade. Em outros termos, só podemos conhecer aquilo que já existe visto que o conhecimento não tem em si a força criadora ou o poder de conferir ser àquilo que ainda não é ou não existe. Assim, o conhecimento ou a reflexão são fundamentais para o desenvolvimento da fenomenologia, embora essa mesma fenomenologia exija o reconhecimento de algo prévio ou imediato que o precede e possibilita sua realização cognitiva.

Neste trabalho estudamos a equação de ondas do tipo p-Laplaciano \'u IND. tt\' - \'DELTA\' IND.p u + \'(- \'DELTA\' POT. alpha\' u IND. t\' = \' [u] POT.q - 2 u, definida num domínio limitado limitado do \'R POT. n\', com 2 \' > ou = \' p < q e 0 < \' alpha\' < 1. Utilizando o método de Faedo-Galerkin provamos a existência de soluções fracas globais para dados iniciais pequenos. Para essas soluções estudamos também o decaimento polinomial da energia associada. A questão da não existência de soluções globais é considerada para o caso em que a energia inicial do sistema é negativa / In this work we study the p-Laplacian wave equation \'u IND. tt\' - \' DELTA\' IND p u + \'(- \'DELTA\' POT. \'alpha\' \' u IND. t\' = \'[u] POT. q - 2 u, defined in a bounded domain of \'R POT n\', with 2 \'> or =\' p < q and 0 < \' alpha\' < 1. By using the Faedo-Galerkin method we prove the existence of weak global solutions for small initial data. We also study the polynomial decay of the associate energy. The blow-up of solutions in finite time is considered for negative initial energy

É possível perceber no decorrer do texto que Tillich apresenta o amor enquanto princípio ético e fundamento ontológico e, por isso, traz consigo muitas ambiguidades. Desta forma, ele explora o conceito de amor a partir daquilo que chama “diferentes qualidades”, tomando como referência as compreensões gregas de eros, philia, epithymia (ou libido) e agápe. A hipótese que norteia este trabalho é que há uma linha de raciocínio presente no pensamento de Tillich, que parece a todo momento insistir na superação das ambiguidades da vida e do caráter fragmentário ao qual está sujeito o ser humano. Por isso, discute-se questões essenciais como seu entendimento sobre ontologia, sua compreensão sobre a importância do mito na linguagem religiosa e sua interpretação da queda como a transição da essência para a existência que resulta na alienação existencial. Mas o foco da dissertação é explorar como Tillich apresenta o poder do amor como aquele que reúne o ser humano com Deus, fundamento de seu ser; com seu próximo; e, principalmente, consigo mesmo. Por fim, o texto expõe como Tillich compreende que a relação entre agápe e eros é essencial para se compreender o amor como uma força una e indivisível, capaz de encerrar as ambiguidades da vida e se apresentar como graça ao ser humano, abrindo possibilidades de superação das leis e da problemática da contextualização da ética nas transições históricas do mundo. / The purpose of this dissertation is to analyze how Paul Tillich understands and relates the concepts of love and ontology in his various works. It is possible to perceive throughout the text that Tillich presents love as an ethical principle and ontological foundation and, therefore, brings with it many ambiguities. In this way, he explores the concept of love from what he calls "different qualities", taking as reference the greek understandings of eros, philia, epithymia (or libido) and agape. The hypothesis that guides this work is that there is a line of reasoning present in Tillich's thought, which seems at all times to insist on overcoming the ambiguities of life and the fragmentary character to which the human being is subjected. Hence, essential questions such as his understanding of ontology, his understanding of the importance of myth in religious language, and his interpretation of the fall as the transition from the essence to the existence that results in existential alienation are discussed. But the focus of the dissertation is to explore how Tillich presents the power of love as one that reunites human being to God, the foundation of his being; with his neighbor; and especially with himself. Finally, the text exposes how Tillich understands that the relationship between agape and eros is essential for understanding love as a single and indivisible force, capable of closing the ambiguities of life and presenting itself as grace to the human being, opening possibilities for overcoming the laws and the problematic of the contextualization of ethics in the historical transitions of the world.

Parte da fronteira deste domínio está em movimento e oscila rapidamente na variável que representa o espaço, caracterizando-se assim como um problema de fronteira livre com multi escala. Este problema tem aplicações, por exemplo, na construção de filmes semicondutores, levando-se em consideração que a superfície do filme se altera pela deposição de vapor químico. O estudo de tal modelo nos remete a questões de existência e unicidade para um sistema elíptico com condições de bordo do tipo misto acoplado à uma equação hiperbólica através de uma condição de fronteira livre. Além disso, um resultado de aproximação por homogeneização é demonstrado. De fato, provamos uma estimativa na norma H1 para o erro que se comete ao aproximar a fronteira livre real por uma fronteira livre homogeneizada / Abstract: In this dissertation we study an elliptic problem in a bounded Lipschitz domain. Part of the boundary is moving and oscillates rapidly in the variable representing the space. Thus, we have a multi-scale free boundary problem. This problem has applications, for instance, in the construction of semiconductor films taking into account that the surface of the film is changing by chemical vapor deposition. The study of such a model leads us to questions of existence and uniqueness for a system involving an elliptic equation with mixed boundary conditions coupled to a hyperbolic equation by means of a free boundary condition. Furthermore, a result on approximation by homogenization is shown. In fact, an estimate in terms of the H1-norm of the error committed by to approximate the real free boundary problem by the homogenized one is proved / Mestrado / Matematica / Mestre em Matemática

Dans cette thèse, on étudie principalement l’équation de Boltzmann homogène 3D pour les potentiels durs et les potentiels modérément mous et l’équivalence entre une EDS à sauts et l’EDP correspondante. En particulier, on calcule le spectre multifractal de certains processus stochastiques, on étudie le caractère bien-posé et la propagation du chaos pour l’équation de Boltzmann. Dans le premier chapitre, on étudie les propriétés trajectorielle pathologiques du processus stochastique (Vt)t_0 représentant l’évolution de la vitesse d’une particule typique dans un gaz modélisé par l’équation de Boltzmann pour les potentiels durs ou modérément mous. Nous montrons que ce processus est multifractal et qu’il a un spectre déterministe. Pour les potentiels durs, nous donnons aussi le spectre multifractal du processus $X_t =\int_0^t V_s ds$, représentant l’évolution de la position de la particule typique. Dans le deuxième chapitre, nous étudions l’unicité de la solution faible à l’équation de Boltzmann dans la classe de toutes les solutions mesures, pour les potentiels modérément mous. Ceci nous permet aussi d’obtenir un taux quantitatif de propagation du chaos pour le système de particules de Nanbu. / This thesis mainly studies the 3D homogeneous Boltzmann equation for hard potentials and moderately soft potentials and the equivalence between some jumping SDE and the corresponding PDE. In particular, we compute the multifractal spectrum of some stochastic processes, study the well-posedness and the propagation of chaos for the Boltzmann equation. The purpose of the first chapter is to study the pathwise properties of the stochastic process $(V_t)_{t\geq0}, representing the time-evolution of the velocity of a typical particle in a gas modeled by the Boltzmann equation for hard or moderately potentials. We show that this process is multifractal and has a deterministic spectrum. For hard potentials, we also give the multifractal spectrum of the process $X_t =\int_0^t V_s ds$, representing the time-evolution of the position of the typical particle. The second chapter is devoted to study the uniqueness of the weak solution to the Boltzmann equation in the class of all measure solutions, in the case of moderately soft potentials. This allows us to obtain a quantitive rate of propagation of chaos for Nanbu particle system for this singular interaction. Finally in the third chapter, we extend Figalli’s work [19] to study the relation between some jumping SDE and the corresponding Fokker-Planck equation. We prove that for any weak solution $(ft)_{t\in[0,T]}$ of the PDE, there exists a weak solution to the SDE of which the time-marginals are given by the family $(f_t)_{t\in[0,T]$

Caractéristique de la littérature noire des années 1960 aux États-Unis, la revendication de l’Être-noir est présente dans les moindres mots écrits par les auteurs africains américains de cette période. William Melvin Kelley, en tant qu’écrivain du Black Arts Movement, le met en avant dans ses œuvres au profit d’une éducation de l’Africain Américain contre la ségrégation et d’autres formes de racisme. Il ne s’agit pas seulement de conceptualiser le Noir par l’écriture, mais surtout de le dépeindre. Selon l’auteur en effet, son rôle est d’abord de mettre en action des personnes, et non pas des idées travesties qui résulteraient d’une quelconque idéologie noire. C’est ce schéma – le passage du monde réel à un monde fictif, ainsi qu’à une représentation idéologique – qui sera étudié dans cette thèse. Il faudra toutefois noter la transformation de l’attitude de l’auteur. En effet, de l’état de simple narrateur, il passe à celui d’activiste. Ce changement est notable par la différence des idées et de la verve entre le premier livre et le dernier publiés par Kelley. Cette évolution de la pensée sera ensuite reliée aux récentes directions prises par l’écrivain. Située au carrefour entre la phénoménologie, la philosophie de l’existentialisme noir, la sociologie ainsi que la littérature, l’analyse qui sera menée aura pour but de mettre en avant l’existence noire vue par William Melvin Kelley. L’auteur ne se place pas seulement en tant que représentant des Noirs, mais comme chargé d’une mission : celle d’aider l’Africain Américain à comprendre la société étatsunienne pour améliorer sa position sociale et culturelle. / Blackness is one of the keywords of the African American literature of the 1960s. It is to be read in each and every word that an Afro-American writer would put down on the paper. As a Black Arts Movement writer, William Melvin Kelley sets blackness forth in his works so that the black population can better struggle against segregation and other forms of racism. Yet, he does not only conceptualize the African American person by writing him or her up, but above all, he depicts them. For Kelley, the role of the author is primarily to show people, not disguised ideas resulting from some other black ideology. It is this pattern – the passage from a real world to a fictitious one, as well as to an ideological representation – that I will study in my dissertation. However, I am first going to note down the transformation in Kelley’s conduct toward race relations as he goes from the narrator to the activist. This change is to be seen in the difference that exists in the verve between his first novel and the last that was published. This renovation will also be linked to the recent direction taken by Kelley in his more recent writings. Phenomenology, Black existentialism, sociology and of course literature will be the bases for this dissertation. The analysis will insist on black existence as seen by William Melvin Kelley. The writer does not only act as a representative of black people, but as one who must help the “Africamerican understand the American society in order to improve his or her social and cultural position.”

The purpose of this thesis was to explore the boundary between human and other created by virtual worlds in contemporary science fiction novels. After a close reading of the three novels: Surface Detail, Existence, and Lady of Mazes, and the application of contemporary literary theories, the boundary presented itself and led to the discovery of where the human becomes other. The human becomes other when it becomes lost to the virtual world and no longer exists or interacts with material reality. Each of the primary texts exhibits both virtual reality and humanity in different ways, and each is explored to find where humanity falls apart. Overall, when these theories are applied to real life there is no real way to avoid the potential for fully immersive virtual worlds, but there are ways to avoid their alienating effects.

This thesis examines the interpretive tradition of Mullā Ṣadrā in the context of the schools of Tehran and Qum. Mullā Ṣadrā’s transcendental philosophy (al-ḥikmah al-mutaʿālīyah or ḥikmat) avails itself to a number of readings; however, this thesis focuses on the philosophical and mystical (ʿirfānī) readings in terms of their development, transmission and their impact on how ḥikmat is understood in the modern Iranian seminary (ḥawza). The way in which a text is read in the ḥawza has great implications for the development of ideas, as the ḥawza uses a text based system to train students in a particular field. While both readings were studied by the majority of transcendental philosophers (ḥukamāʾ) in the school of Tehran, the school of Qum saw a greater separation between the readings and I show that for a number of reasons, including the introduction of seminal texts written by ʿAllāmah Ṭabāṭabāʾī, a preference developed for a more philosophical reading of transcendental philosophy. I examine evidence for the different preferences of the ḥukamāʾ for either a more philosophical or ʿirfānī reading of ḥikmat through an examination of their writings on the subjects of existence (wujūd), guardianship (walāyah) and resurrection (maʿād) which act as case studies. The theoretical implications of both approaches are examined in each chapter as well as their interdependence. The schools of Tehran and Qum built on Mullā Ṣadrā’s framework and provided new interpretations of important issues. Apart from the intricate discussions on the core aspects of ḥikmat, Muḥammad Riżā Qumshihī’s masterful examination of the Seal of the Saints and ʿAlī Mudarris Zunūzī’s philosophy of bodily resurrection are examples of a thriving interpretive tradition in Iran and constitute significant developments of important philosophical and ʿirfānī concepts from the ideas of their predecessors.

This thesis is aimed at learning selected aspects of the private health insurance system in OECD countries and its co-existence side by side with the public health insurance. Introductory chapters describe theoretic starting points and principles of functioning of the health insurance system in harmony with existing models of the healthcare policy. The analytical part of the thesis, using qualitative methods of investigation, deals with the development and the current state of the system of the health insurance in the Czech Republic from 1989 and characterizes briefly major problems being encountered and solved. Furthermore, the thesis maps trends of the health insurance in selected OECD countries, showing issues within the structure of healthcare system expenses in countries followed and their influence on the system of the health insurance. The thesis is also informing about present problems on the private health insurance market in OECD countries precisely as described in a study made by the Organization for Economic Co-operation and Development. The final chapter compares the mentioned health insurance systems from the point of view of co-payment and co-existence.
