As transformações na reprodução fictícia do capital na agroindústria canavieira paulista: do Proálcool à crise de 2008 / The transformations on sugarcane agroindustry fictitious capital reproduction in São Paulo: from the Proálcool to 2008 crisis

Pitta, Fábio Teixeira 03 March 2016 (has links)
A tese por nós aqui apresentada teve por finalidade principal pesquisar a transformação na forma crítica de reprodução fictícia da agroindústria canavieira paulista, entre o Proálcool (1975 1990) e aquela forma de reprodução que começou a se constituir a partir da década de 1990, mas só se estabeleceu no início do século XXI. Para tanto, visitamos teóricos da reprodução e crise do capital que nos auxiliaram a compreender as formas de reprodução fictícia do capital em nível global atualmente, para depois podermos cotejar suas interpretações com a pesquisa por nós realizada acerca da forma atual de reprodução fictícia desta agroindústria canavieira a partir da inflação do preço do açúcar como ativo financeiro nos mercados de futuros internacionais (derivativos). Tal pesquisa nos permitiu abordarmos, também, os impactos da crise econômica do capital de 2007/2008 sobre tal agroindústria, a fim de relacionarmos tal crise com uma discussão sobre a própria crise imanente do capital. As consequências dessa transformação na reprodução fictícia acima mencionada também foram observadas no que diz respeito à terra, conforme características da produção, produtividade e área com cana-de-açúcar; e ao trabalho, por meio da discussão acerca do trabalho do boia-fria e da mecanização do corte de cana-de-açúcar. Podermos sugerir a crise da reprodução da sociabilidade capitalista por meio da historicização de suas categorias (capital, terra e trabalho) atualmente em crise, nos fundamentou para desdobrarmos a crítica da forma mercadoria de relação social e do trabalho como fundamento do capital como ponto de chegada da crítica negativa que pretendemos apresentar como basilar para o movimento do texto como um todo. / The thesis we present here had as its main purpose the research in the transformation of the critical form of sugarcane agroindustry fictitious reproduction, in São Paulo State, between the Proálcool (1975 1990) and the form that started to be constituted in the nineties but only was stablished in the beginning of the twenty first century. Therefore, which helped us to understand the actual forms of global fictitious reproduction of capitalism and then we compared these interpretations with a research about the present form of sugarcane agroindustry fictitious reproduction in the State of São Paulo, which is characterized by sugar price inflation as a financial asset negotiated in international future markets (as a derivative). That research allowed us to approach the impacts in such sugarcane agroindustry of capital economic crisis of 2007/2008 and to relate this crisis with a discussion about capital immanent crisis. The consequences of the mentioned transformation in the sugarcane agroindustry fictitious reproduction in the State of São Paulo also have been observed with regard to land by characterizing sugarcane production, productivity and area; and to labor, through the discussion of boia-fria conditions of labor and the mechanization of sugarcane harvesting. Our suggestion of capitalist social reproduction crisis because of the historical character of its categories (capital, land and labor), currently in crisis, allowed us to unfold the critique to commodity form of social relation and labor as the fundament of capital as the ultimate purpose of the negative critique we intended for the totality of this text.

Méthodes de domaines fictifs pour les éléments finis, application à la mécanique des structures / Fictitious domain methods for finite element methods, application to structural mechanics

Fabre, Mathieu 10 July 2015 (has links)
Cette thèse est consacrée à l’étude de méthodes de domaines fictifs pour les éléments finis. Ces méthodes, initialement conçues pour l’approximation de problèmes d’interactions fluide/structure, consistent à prolonger un domaine réel par un domaine de géométrie simple appelé domaine fictif. On applique ces méthodes à un problème de contact unilatéral sans frottement en petite déformation entre deux corps élastiques séparés par une distance initiale non nulle et possédant par ailleurs des conditions aux bords de type Dirichlet et Neumann. Les deux premiers chapitres sont consacrés à l’introduction des méthodes de domaines fictifs et du problème unilatéral de contact de deux corps élastiques. Le chapitre 3 est consacré à l’analyse a priori et à l’étude numérique de ce problème de contact en domaine fictif avec les conditions aux bords de Dirichlet et de contact qui sont prises en compte à l’aide d’une méthode de type Nitsche. Des résultats théoriques de consistance de la méthode discrète, d’existence et d’unicité sont présentés. Afin d’obtenir une estimation d’erreur a priori optimale, une stabilisation de la méthode de domaine fictif est nécessaire. Ces résultats sont validés numériquement sur des cas tests en dimensions deux et trois. Le chapitre 4 est consacré à l’étude d’un estimateur d’erreur de type résidu d’un problème de contact sans domaine fictif entre un corps élastique et un corps rigide. Les résultats théoriques sont également validés sur deux cas tests numériques : un domaine rectangulaire avec seulement une partie de la zone de contact en contact effectif ainsi qu’un contact de type Hertz en dimensions deux et trois. Le chapitre 5 est une généralisation du chapitre 4 à l’approche domaine fictif et au cas de deux corps élastiques. / This thesis is dedicated to the study of the fictitious domain methods for the finite element methods. These methods, initially designed for the fluid-structure interaction, consist in immersing the real domain in a simply-shaped and a geometrically bigger domain called the fictitious domain. We apply these methods to a unilateral frictionless contact problem in small deformation of two deformable elastics bodies separated by an initial gap and satisfying boundary Dirichlet and Neumann conditions. The first two chapters are devoted to the introduction of these methods and to the unilateral contact problem. The chapter 3 is dedicated to a theoretical study for Dirichlet and contact boundary conditions taken into account with a Nitsche type method. Some theoretical results are presented: the consistency of the discrete method, existence and uniqueness results. To obtain an optimal a priori error estimate, a stabilized fictitious domain method is necessary. These results are numerically validated using Hertz contact in two and three dimensions. The chapter 4 is devoted to the study of a residual-based a posteriori error estimator, without the fictitious domain approach, between an elastic body and rigid obstacle. The numerical study of two tests cases will be performed: a rectangular domain with only a part of the potential zone of contact in effective contact as well as a Hertz contact in two and three dimensions. The chapter 5 is a generalization of the chapter 4 to the fictitious domain approach and the care of to two elastics bodies.

Modélisation et simulation numériques de l'érosion par méthode DDFV / Modelling and numerical simulation of erosion by DDFV method

Lakhlili, Jalal 20 November 2015 (has links)
L’objectif de cette étude est de simuler l’érosion d’un sol cohésif sous l’effet d’un écoulement incompressible. Le modèle élaboré décrit une vitesse d’érosion interfaciale qui dépend de la contrainte de cisaillement de l’écoulement. La modélisation numérique proposée est une approche eulérienne, où une méthode de pénalisation de domaines est utilisée pour résoudre les équations de Navier-Stokes autour d’un obstacle. L’interface eau/sol est décrite par une fonction Level Set couplée à une loi d’érosion à seuil.L’approximation numérique est basée sur un schéma DDFV (Discrete Duality Finite Volume) autorisant des raffinements locaux sur maillages non-conformes et non-structurés. L’approche par pénalisation a mis en évidence une couche limite d'inconsistance à l'interface fluide/solide lors du calcul de la contrainte de cisaillement. Deux approches sont proposées pour estimer précisément la contrainte de ce problème à frontière libre. La pertinence du modèle à prédire l’érosion interfaciale du sol est confirmée par la présentation de plusieurs résultats de simulation, qui offrent une meilleure évaluation et compréhension des phénomènes d'érosion / This study focuses on the numerical modelling of the interfacial erosion occurring at a cohesive soil undergoing an incompressible flow process. The model assumes that the erosion velocity is driven by a fluid shear stress at the water/soil interface. The numerical modelling is based on the eulerian approach: a penalization procedure is used to compute Navier-Stokes equations around soil obstacle, with a fictitious domain method, in order to avoid body- fitted unstructured meshes. The water/soil interface’s evolution is described by a Level Set function coupled to a threshold erosion law.Because we use adaptive mesh refinement, we develop a Discrete Duality Finite Volume scheme (DDFV), which allows non-conforming and non-structured meshes. The penalization method, used to take into account a free velocity in the soil with non-body-fitted mesh, introduces an inaccurate shear stress at the interface. We propose two approaches to compute accurately the erosion velocity of this free boundary problem. The ability of the model to predict the interfacial erosion of soils is confirmed by presenting several simulations that provide better evaluation and comprehension of erosion phenomena.

知識經濟下的大學學術生產體制與研究生的學術勞動:政治經濟學批判 / The academic production regime and the laboring of graduates in the knowledge economy: political economy perspective

曾翔, Zeng, Siang Unknown Date (has links)
本文嘗試以政治經濟學的取徑,研究當代高等教育的轉型與資本主義的連結。 本文以Marx對資本主義的批判為基礎,並結合Polanyi對虛構商品的考察,以及Jessop對知識的虛構商品化的論證,本文以為,在知識經濟的時代當中,知識被「虛構」為商品與資本,將知識勞動者收編至剝削的生產關係之中;在此,知識不僅只是經濟長波的關鍵,也是資本的競爭力-佔有超額利潤的能力,的關鍵所在。也因而,生產知識的場域,尤其是大學,就被捲入了資本主義之中,成為學術生產體制。 而被捲入資本主義的大學知識勞動者不僅只有教授或研究、教學人員,當中,又以研究生最為特殊,他們是「被生產的勞動力商品,同時又是生產知識商品的勞動力」。本文提出了勞動學習的概念,並以「是否直接生產剩餘價值」和「是否承受市場壓力」檢視研究生的勞動學習。本文以臺灣大學工會的案例,探討在勞動與學習混合為一的「勞動學習過程」、「學術外包」以及「名為助學的薪資與工作內容」的作用底下,研究生承受市場壓力,並被排除在勞動法制的保障之外的情形。 但是依照「有勞動事實就必須有勞動保護」的原則,本文以適用勞動法的各種要件主張研究生應適用勞動法令並享有各種勞動權,並得組成工會進行團體協商、維護自身權益。 最後,本文認為,我們必須正視資本主義式的學術生產體制對於研究生的剝削與壓迫,承認師、校、生之間的矛盾,進而團結抵抗資本主義的不斷擴張。 / This dissertation tried to examine the interconnection between the transformation of higher education and capitalism from political economy perspective. Based on the critique on capitalism by Marx, the inspection on fictitious commodity by Polanyi and the account of commoditization of knowledge of Jessop, this dissertation argues that, in the so-called knowledge economy, knowledge presents as the form of commodity and capital, and subsequently subsumes the knowledge worker into the exploited relation of production under capitalism. Besides, knowledge is also the key to create “long wave”, and more importantly, the competency of capital, which allows capital to gain surplus profits in the competition. With the development of knowledge economy, university has been transformed as “Academic Production Regime”. The graduates are also been subsumed into the Academic Production Regime. They are unique in this regime because they are “produced commodity of labor power, and also the labor power to produce commodity”. I bring up the concept of “learning by laboring” to examine, “Do the graduates produce surplus value?” and “Do the graduates endure the press from market?” With the case of Taiwan University Union, I asserted that the mixture of laboring and learning, academic subcontracting, and grant of student aid obscured the exploitation to graduates. Graduates now endure the press from market and be ignored by the protection of labor laws. I investigated the controversy of applying graduates employees to labor law, and argue that every labor should be protected by labor law. Finally, I contended that we shall confront the conflict between graduates, faculty and the university, and uniting to against the spread of capitalism

Funny little witches and venerable-looking wizards: a social constructionist study of the portrayal of gender in the Harry Potter series

Rodrigues, Debbie June 02 1900 (has links)
In this study I apply social constructionism as propounded by Vivian Burr (1998) to show that although J. K. Rowling uses stereotypes in the Harry Potter series as a reflection of how gender is constructed across a wide range of societal institutions in contemporary Britain, she created complex characters who on an individual level subvert social constructs and thereby offers her readers alternatives to culturally defined concepts of gender. I explore the all-pervasive social phenomenon of gender and examine how it is constructed in present-day Britain and reflected in the series (bearing in mind that the first book was published in 1997 and the last one in 2007). My analysis of female and male characters in the books, and their interpersonal relationships, shows that Rowling's often tricky portrayal of femininities and masculinities gives us an honest view of teenagers’ lives and contemporary gender relations in an ever-changing, complex world. / English Studies / M.

The fortifying and destructive power of love in J.K. Rowling’s Harry Potter series

Gani, Safiyyah 03 1900 (has links)
The aim of this study is to explore the importance of love in its various manifestations in the lives of the Harry Potter characters and its power to consequently influence the paths that they eventually choose to walk. Love is investigated as the reason behind the choice between good and evil as well as paradoxically both a fortifying as well as a destructive force. Furthermore, it attempts to examine the importance that love plays in the healthy or dysfunctional development of the characters. Numerous philosophies and theories that span two different eras will form the theoretical framework of this research paper. There will be a constant interplay between the theories and the main text, that is, the seven Harry Potter books that together represent the Harry Potter series. Additionally, the author‟s opinion acquired from invaluable fan interviews will be utilized in order to improve the understanding of the characters motivations. The introduction is a brief explanation of key terms and theories that are essential to the exploration of love in the Harry Potter series. The study comprises five chapters. The first three chapters are concerned with the three main manifestations of love represented in the series, namely; parental love, friendship and romance respectively. Chapter Four focuses on the adaptation of the novels into movies and the subsequent result that this has on the depiction of love. Chapter Five highlights the finding of the study conducted. / English Studies / M.A. (English)

Konstruované jazyky v literatuře / Constructed languages in literature

Jelínek, Jiří January 2018 (has links)
The PhD thesis "Constructed Languages in Literature" focuses on the phenomenon of consciously designed or drafted languages and their usage in literary texts. The first chapter of the thesis offers reflections on the delimitation of constructed languages, especially from the perspective of the mostly illusory opposition of natural and constructed. It also puts forth the problems of glossolalia and encryption or encoding of a text in a natural language, while suggesting these two ways to create a new utterance should be perceived as possible starting points for language creativity, rather than a completely different phenomenon. The subsequent chapters then turn to individual cases and introduce extensive groups of constructed and virtual languages - animal languages, utopian and dystopian languages, sacred and divine languages and constructed and virtual languages in poetry. In those chapters examples of both elaborated and drafted languages appear, so that the imagination characteristic of each group comes out.
