The semi-classical black hole tunnelling method is a useful technique to calculate black hole temperature and understand black hole thermodynamics. I will investigate the black hole tunnelling method in detail. I will compare two different approaches used to calculate black hole tunnelling. The tunnelling method can be applied to a broad range of spacetimes and I will show this explicitly in order to demonstrate the robustness of the tunnelling technique. In particular, I will apply the tunnelling method to spacetimes including: Rindler (the method can recover the Unruh temperature), and more general spacetimes (such as Kerr-Newman and Taub-NUT). I will also discuss the 5d Kerr-Gödel spacetimes in detail (while showing a previous unobserved property of these spaces). Once the parameter space of Kerr-Gödel is understood in detail, I will show how the tunnelling method can also be successfully applied to the Kerr-Gödel black hole. Finally, the key result of my thesis involves extending the tunnelling method to model fermion emission. The previous tunnelling calculations all involved the emission of scalar particles. I will model the emission of spin-1/2 fermions from various spacetimes including the Rindler spacetime and general non-rotating black holes. I will also model the emission of charged spin-1/2 fermions from the Kerr-Newman spacetime to show that the method is also applicable to rotating spacetimes. In all these cases I show that the correct Hawking temperature (Unruh temperature in the case of Rindler) is recovered for spin-1/2 fermion emission. Although this final result is not surprising, it is an important result because it confirms that Dirac particles will radiate from the black hole at the same temperature as scalar particles. It has always been assumed that this is the case but there is very little literature involving fermion radiation of black holes. So the results of my calculations are twofold, I demonstrate that Dirac particles are emitted at the same temperature as scalar particles from a black hole and it shows how robust the semi-classical tunnelling technique is.

This paper explores and interrogates late Victorian anxieties concerning the issues of masculinity and labor, taking Thomas Hardy’s Jude the Obscure as a key text in this discourse. I argue that Hardy, drawing upon his own experiences, offers a meditation on the differing Victorian modes of masculinity outlined and embodied in the thought of John Henry Newman and Thomas Carlyle, and in doing so, constructs a dialectical tension between already outmoded, yet remarkably persistent, answers to the questions and pressures of modernity. Through the use of one of the text’s central images—that of Christminster and its accompanying Gothic architecture—Hardy creates an opposition between an idealized intellectual labor and the earthy reality of manual labor. Both forms—figured in either the heroic and organic terms of Carlyle or the reserved, tradition-bound reaction of Newman—represent the ideal that allows Jude to live, but also the force that leads to his death. Therefore, in the clash between the ideal and real, the dialectic fails to deliver a possible synthesis, and instead spirals restlessly in the darkened gaps of self-negation. At the same time, because the specter of a crude social and biological Darwinism consciously haunts the edges of the story, the dialectic never stops demanding a synthesis if Jude is to discover the grounding for a fully integrated identity or ethics. The central question for Hardy thus becomes one of form: For a modern masculine subjectivity to take hold, external social forms must have a connective vitality with interior dispositions, a proposition that Hardy views as a near impossibility. / text

The Postanarchist, an activist in a heterotopia : building an ideal type is the theme of this doctoral thesis. The main aim is to elaborate a design for the postanarchist figure, picking up its main characteristics from the work of the postanarchist Saul Newman. The argument also bears on two other authors: the post-structuralist Michel Foucault, considered a strong influence of postanarchism, and Pierre-Joseph Proudhon, the first author who labelled himself as anarchist and the first to embrace anarchy positively. Immanuel Kant, Friedrich Nietzsche, Gilles Deleuze and Félix Guattari are introduced as mediators to provide deeper understanding of the main authors. The dissertation offers a novel theoretical revision of postanarchism through Michel Foucault and Pierre-Joseph Proudhon. It notes the close similarities between Foucault and Proudhon - in terms of concepts of space, struggle, movement, necessity and consequently anarchy; establishes a conceptual net around them and uses Proudhon s thinking to fill the bibliographic gaps in Foucault s writings. The goal is to better understand the thought and the activist practice of Foucault in terms of anarchism and, in the last instance, to better grasp the postanarchism of Saul Newman in order to carve the postanarchist ideal type. Postanarchism is understood as the constitution of autonomous spaces; the notions of space and heterotopias - the Foucauldian space - are central in the dissertation. Accordingly, the thesis is structured by three hypotheses: (i) postanarchism is space constitution; (ii) the constitution of space is a struggle; (iii) to establish space is to survive. The sub-concepts of the dissertation are: movement, necessity, struggle, power subject, body, sign, truth and utopia. The thesis provides an interpretative analysis of primary sources - books, newspapers, magazines, pamphlets and manifestos - of the three main authors supported by secondary commentaries. It departs from conventions by adopting a theoretical approach inspired by Foucault s solar and circular worldview (and Tommaso Campanella s City of the Sun). This facilitates the fluid organization of the argument and avoids imposing linearity on the content, thus highlighting the interrelation between content and the structure of the argument. This thesis is an exposition, an interpretation that develops new knowledge through the connections and methods that enable us to better know who the postanarchist activist is.

Lema Sabachtani, realizada em 1966, por Barnett Newman, assim como sobre a natureza desta associação e como ela pode ser abordada pela História da Arte, teórica e metodologicamente. Esta pesquisa trata, portanto, da espessura do olhar entre aquele que vê a obra de arte e a própria obra porque trata dos espaço-tempi em que sua percepção se abre a uma rede de relações. Diante de uma obra nos desfiguramos e reconfiguramos enquanto sua imagem se modifica. Mas quando a obra concerne a uma transformação exemplar, esses conteúdos de desdobram e se redobram em inúmeras questões, como é o caso do tema da transformação mais recorrente em nossa cultura cristã e ocidental, no grande drama expresso pela Paixão. O interesse por essas obras, portanto, foi imposta pela expressa categoria de identificação autoimpingida do artista com o tema, com o pathos do processo de criação e com a temporalidade complexa que a constelação dessas obras acaba por sedimentar. Assim, a investigação levou à reflexão sobre o impacto do jogo entre o pathos e o anacronismo sobre o discurso na História da Arte como montagem de tempos heterogêneos, baseada em pressupostos oferecidos por Aby Warburg, Walter Benjamin e Georges Didi-Huberman. _______________________________________________________________________________________ ABSTRACT / The subject of this PhD research project is the association of Henri Matisse's Chemin de la Croix, Barnett Newman's Stations of the Cross. Lema Sabachtani Exhibition and Bené Fonteles' Sudários, as well as what the order of this association and how it can be brought up by Art History, theoretically and methodologically. Therefore, this research is about of the thickness of the outlook between the one who sees the artwork and the artwork itself, because it talks about the space-times in that perception that opens itself into a web of relations. In front of an artwork we desfigure and reconfigure ourselves as the image modifies. But when the artwork approaches to a model transformation, these contents unfold and refold themselves in numerous questions. That is the case of the more recurrent transformations in our Western Christian culture, in the great drama expressed by the Passion. The interest by these artworks, therefore, was imposed by the artist’s self-inflicted identification category with the subject, with the pathos of the creation process and with the complexity of the temporality that the constellation of these works deposits. Thus, the inquiry induced to the speculation about the impact of the relation between the pathos and the anachronism about the discourse in the Art History as montage of heterogeneous times, based in presuppositions offered by Aby Warburg, Walter Benjamin and Georges Didi-Huberman.

Syntax, word usage, and paragraph development form the substance of the analysis of the Apologia. The use of subordination, repetition, and antithesis in sentence construction; the choice of words to produce rhythm and prove mood, as well as the implied metaphor; and careful blending of these elements into an organic unity which reflect not only the personality of the man, but his very thought process; these are the common elements identified by critics of the Apologia. To what extent these elements exist in the prose of the university sermons, and what other elements of style are identifiable in these sermons are the subject of this paper.

The colorful history of Mormon polygamy has many interesting stories to tell, and one of the most interesting is that of Rev. Dr. J. P. Newman's debate with the Mormon Apostle Orson Pratt on "Does the Bible Sanction Polygamy?" This debate was held at the New Tabernacle in Salt Lake City, Utah, on August 12, 13, and 14, 1870. Newman was the Chaplain of the United States Senate and one of the foremost preachers of Washington, D.C. His appearance in Salt Lake City to debate the question of polygamy was a national topic. Probably never before, nor since, has so much been said in such a short time by non-Mormon presses on a question respecting Mormonism. And never before, as far as the author has been able to discover, has a chaplain of the Senate engaged in a public debate of such wide-spread interest.

This dissertation provides an analysis of the attempts by John Henry Newman to account for the historical reality of doctrinal change within Christianity in the light of his lasting conviction that the idea of Christianity is fixed by reference to the dogmatic content of the deposit of faith. The existing literature on Newman is enormous and wide-ranging but this present work fills a notable gap by treating Newman at any particular point in the account as a person with an open future, where his present acts are not determined by later events, and where any apologetic intent has to be identified and accounted for by reference to the immediate matter under consideration and the contemporaneous evidence. The argument of the thesis is that Newman proposed a series of hypotheses to account for the apparent contradiction between change and continuity, that this series begins much earlier than is generally recognised and that the final hypothesis he was to propose, contained in An Essay on the Development of Christian Doctrine, (‘Essay’), provided a methodology of lasting theological value. The introduction establishes the centrality of the problem of change and continuity to Newman's theological work as an Anglican, its part in his conversion to Roman Catholicism and its contemporary relevance to Roman Catholic theology. It also surveys the major secondary literature relating to the question, with particular reference to those works published within the last fifty years. In the first main chapter, covering the period to the publication of his first major work, The Arians of the Fourth Century, in 1833, Newman's earliest awareness of the problem and first attempts to solve it are considered. The growing confidence of Newman's Tractarian period and his development of the notion of the Via Media form the second chapter and the collapse of that confidence, the subject matter of the third. The fourth chapter is concerned with the emergence of the theory of development and the writing and content of the Essay. The conclusion considers the legacy of the Essay as a tool in Newman’s theology and in the work of later theologians, finally suggesting that it may offer a useful methodological contribution to the contemporary Roman Catholic debate about hermeneutical approaches to the Second Vatican Council.

Il a entre autres réalisé plusieurs tableaux sur le thème de la Crucifixion, un sujet particulièrement délicat pour un artiste attaché à son identité juive et à un art à tendance autobiographique. Ce mémoire examine les conditions qui ont permis l’adoption et le développement, par Chagall, d’une iconographie revisitée d’un important motif chrétien. Parmi les circonstances qui ont facilité l’hybridation culturelle à laquelle se livre Chagall dans ses Crucifixions, il faut signaler la liberté nouvelle, à la fois au niveau des dispositifs figuratifs et du traitement pictural, apportée par le modernisme dans l’approche des grands genres traditionnels dont relève la peinture religieuse. Dans un tout autre registre, le mémoire se penche sur les circonstances historiques exceptionnelles ayant exercé une pression pour que l’expérience tragique des Juifs du XXe siècle trouve à s’exprimer dans des images à portée universelle. / Marc Chagall is a Jewish artist who challenged the Mosaic interdiction to represent the deity. He has among others in the modern period made several paintings on the theme of the Crucifixion, a particularly sensitive issue for an artist attached to his Jewish identity and practising an art with a strong autobiographical component. This dissertation examines the conditions which allowed the adoption and the development, by Chagall, of an important Christian subject whose iconography he freely revisited. Among the circumstances that facilitated the cultural hybridization in which Chagall engaged in his Crucifixion, we must point out the new freedom, both at the level of figurative devices and pictorial treatment, brought by modernism in the approach of major traditional genres to which religious painting belongs. On a quite different register, the dissertation examines the exceptional historic circumstances met by Chagall before and during the execution of the Crucifixions. These circumstances have exerted pressure that allowed the tragic experience of the Jews of the XXth century to find expression in images of universal significance.

A defining feature of American abstract expressionist painting is its enormous size and scale. Heroic ambition, the vast American landscape, and the sense of "something big" happening in American painting are often cited as determining factors in this phenomenon. This dissertation examines how Jackson Pollock, Barnett Newman, and Mark Rothko not only painted large-scale canvases but, following trends in modern architecture, shifted their painting towards the construction of architectural environments, thus promoting the transformation of painting from a window in the wall to a wall without a window. The artist and architect Tony Smith, a close friend and colleague of these painters, played an active role in encouraging their interest in modern architecture. As a result of their investigations into the physical, as well as conceptual, limits of the canvas, these artists shifted the viewer’s experience from a perceptual experience of pictorial space to a physical encounter with actual space. In contradiction to the notion of the purely optical, one could describe this as a somatic viewing experience, tactile and active, which anticipated specific concerns of 1960s minimalism. This achievement redefines Pollock's, Newman's, and Rothko's legacy to the subsequent generation of artists and places their production into a broader historical framework. / text
