<p>This dissertation examines the thought of Jean-Luc Marion in light of his treatment of divine revelation and in connection to the hermeneutic phenomenology of Paul Ricoeur. It argues, first, that Marion’s thought bears within itself significant ambiguities that are determined by the legacies of the key concepts which organize his work: ‘givenness’ (<em>donation</em>) and saturation. Secondly, it also argues that even if a way can be found to resolve these ambiguities the resultant proposal does not meet the criticism raised by Paul Ricoeur in reference to phenomenologies of religion that remain determined by a ‘Husserlian idealism.’ As a result, the dissertation offers a study of Ricoeur’s hermeneutics of revelation in an effort to displace Marion’s account and offer an alternative proposal. Specifically, it treats the connection of Ricoeur’s proposed transformation of phenomenology through hermeneutics, the idea of a hermeneutics of testimony that is generated as a result of that transformation, and Ricoeur’s notion of revelation as being articulated in reference to the ‘world of the text.’ By focusing on the notion of ‘anteriority’ throughout the analysis, the dissertation argues that not only does Marion’s work remain limited by its formal commitments to pure apparition, but it fails to access the sort of radical anteriority that it seeks. This is so because it remains tied to a philosophy of consciousness which is blocked from accessing the pre-reflective level of belonging that is made accessible by Ricoeur’s hermeneutic phenomenology. By making this argument, the dissertation provides a critical analysis of Marion’s work from the perspective of divine revelation and, furthermore, brings that work into conversation with Paul Ricoeur. This important engagement between Ricoeur and Marion has not been adequately addressed in the current secondary literature and this dissertation fills that gap.</p> / Doctor of Philosophy (PhD)

Ce mémoire de maîtrise porte sur l’intégration de l’improvisation dans la création de trois de mes œuvres récentes. Ces œuvres sont : Nyctophilia – minimum 11’00’’ – pour quatuor à cordes et soliste improvisateur ; Æther – 10’ – pour trio à instrumentation non définie ; Presqu’étoile – 10’ – pour grand orchestre. En guise d’introduction, je présente mes préoccupations artistiques, l’origine de mon travail ainsi que la dualité qui semble opposer l’improvisation et la composition. Je dresse ensuite, en lien avec mes influences personnelles, un bref portrait de l’improvisation dans le jazz et dans la musique savante axé sur la seconde moitié du 20e siècle. Finalement, les œuvres font l’objet d’une analyse ciblée afin de démontrer les moyens utilisés pour intégrer l’improvisation dans la composition. Chacune des trois œuvres expose un moyen spécifique issu de ma réflexion et de mes recherches afin de gérer l’improvisation : Nyctophilia – axe de gestion de l’information ; Æther – conversationnalité et improvisation libre ; Presqu’étoile – comprovisation à partir d’Æther. / The focus of this master’s thesis is the integration of improvisation in three of my recent pieces: Nyctophilia – minimum 11’00’’ – for string quartet and soloist improviser ; Æther – 10’’ – for a trio of undetermined instruments ; Presqu’étoile – for full orchestra. As an introduction, I present my artistic concerns, the origin of my work, and the seeming duality that places improvisation in opposition to composition. Then I draw, according to my personal influences, a brief portrait of improvisation in jazz and in art music, primarily in the second half of the 20th century. Finally, I analyze three of my pieces to show the means utilized to integrate improvisation into composition. Each piece exhibits a specific way to manage the inclusion of improvisation, these methods being the result of my reflections and research. Nyctophilia – axis as a means of information management ; Æther – conversationnality and free improvisation ; Presqu’étoile – comprovisation in relation to Æther.

Ma pratique de l'art numérique m'amène à m'interroger sur la dialectique entre le réseau technique et la création d'une oeuvre. La question devient particulièrement intéressante lorsque l'environnement instrumental est purement artificiel et que l'oeuvre dépend d'une dimension technologique pour être vécue. Cette problématique est explorée à travers Ce qu'il reste (2010) une oeuvre réalisée dans le cadre de ce projet de recherche.

Tableau d'honneur de la Faculté des études supérieures et postdoctorales, 2011-2012 / Ce mémoire, dans le sillon du tournant anthropologique en théologie, se déploie à partir d'une question principale portant sur les conditions de la réception de la parole dans le sujet. Notre démarche, balisée par le cadre théorique de la sémiotique discursive, s'appuie sur une perspective de renonciation et son sujet insistant sur la dimension intersubjective du langage et sur l'altérité radicale de la parole. Plus spécifiquement, elle propose la lecture sémiotique du récit de la dernière Cène de l'évangile lucanien comme lieu privilégié d'élaboration d'un modèle d'anthropologie structurale visant l'intelligibilité du parcours du Verbe dans la chair. L'enjeu fondamental de cette anthropologie, renvoyant à la structure même du salut, concerne le déplacement du sujet vers une position filiale relative à la parole originaire et à la communion. Cette recherche achève son mouvement dans la mise en interaction de ce modèle anthropologique, référé au « devenir serviteur de la parole », avec ceux des jésuites et psychanalystes lacaniens, Denis Vasse et Michel de Certeau.

Tableau d'honneur de la Faculté des études supérieures et postdoctorales, 2006-2007 / Partie création : II s'agit d'une adaptation de la nouvelle Berlin rêvé sous forme de faux documentaire sur un écrivain qui n'a jamais existé. Antoine Lemay : l'histoire d'une passion raconte l'histoire d'un auteur obsédé par la ville de Berlin. Pendant des années, il a écrit des textes se passant dans cette ville sans jamais y mettre les pieds. Un jour, il entend parler d'un concours radiophonique pour gagner un voyage à Berlin. Il y voit un signe du destin et participe. Il fait partie des gagnants, mais découvre, avant de partir, qu'il s'agit d'un voyage organisé. Il choisit donc de ne pas y aller et s'enferme chez lui où il rêve un voyage à Berlin. Partie essai : Nous avons cherché à voir s'il est possible de faire un film fantastique en adoptant la forme du documentaire. Nous avons donc étudié différents films appartenant au genre du documenteur (faux documentaire) et au genre fantastique pour les comparer avec le scénario Antoine Lemay : l'histoire d'une passion.

Polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) are common contaminants of sediment, soils and biological tissues. These compounds pose a significant risk to biological and ecosystem health and functioning due to these compounds being mutagenic, carcinogenic and are known to disrupt the endocrine system. The bioaccumulation and biomagnification potential that these compounds possess mean that they are capable of affecting the entire food chain and are not limited to the organisms that are directly in contact with the compounds Even though there has been an increase in the attention on identifying the presence and impacts that these compounds may have in South Africa, the level of attention is lower than what it is in other countries around the world. Although South Africa has guidelines in place for other pollutants, such as metals, there are no such guidelines in place to monitor PAHs and PCBs.. Industries are known to release both PAHs and PCBs, mainly from incomplete burning processes and the release of oils and fuels in the case of PAHs, and from heat transfer fluids in the case of PCBs. Durban Bay and surrounding areas of eThekwini, KwaZulu-Natal are highly industrialised with many aquatic systems, in which these contaminants are likely to deposit. The aim of this research was to determine the concentrations of these compounds by means of chemical analysis and additionally biological analysis, using the H4IIE-luc bioassay and compare these levels to international guideline levels. It was found that the concentrations of the 23 analysed PAHs were 6.5–3 235.6 ng.g-1 and the concentration of the PCBs analysed were 0–113.83 ng.g-1. Many sites were found to be in exceedance of the guideline limits, particularly in the harbour. Toxic equivalency factors (TEF) were used to gauge the toxic equivalency (TEQ) of the PAHs and PCBs that were found. The TEQs were generally low, and were below any guideline levels. The assay revealed the extract containing the PCBs had a bioassay equivalence (BEQ) of 0–93.54 pgTCDDeq. g-1 and the extract containing the PAHs of 0–776.08 pgTCDD-eq.g-1. With a proportion of the sites exceeding guideline limits. The BEQ results were two to three orders of magnitude greater than the TEQs calculated from the concentrations determined by the instrumental analysis, however, followed a similar trend. Additionally chemical analysis was not performed on a full suite of compounds that are able to elicit a response from the cells, which could be a reason why the BEQ and TEQ did not follow a similar trend among some of the samples. It would have been more beneficial to have performed chemical analysis on the 16 priority PAHs (as determined by the United States Environmental Protection Agency), the dioxin-like PCBs and polychlorinated dibenzo-p-dioxins (PCDD) and polychlorinated dibenzofurans (PCDFs) which are all capable of eliciting a response from the cells and have TEF values. The areas that were most affected by contamination of these compounds was the harbour and surrounding canals, and there was point source contamination along the Umhlatuzana, Umbilo, and Amanzimnyana Rivers. All dl-PCBs should be chemically analysed at all the sample areas, as these cause adverse effects to biota. In addition to this, biota should be sampled to determine concentrations of the compounds to determine bioavailability and the degree of bioaccumulation in the food chain. Utilising biomarkers it would be possible to determine stresses of fish. / MSc (Environmental Sciences), North-West University, Potchefstroom Campus, 2014

My thesis focuses on philosophical themes implicit in corridor conservation, using the Big Thicket National Preserve as an example. The way in which corridors, boundaries and communities are ambiguous, as both limits and connections, is dealt with. Corridor-patch matrices assemble ecological and human groups into temporary communities, often with conflicting interests. Such constellations foreground how a foreigner's boundary crossing is a notion important to both conservation and a philosophical study of being, seen as being always in relation with otherness. In this context, the notion of foreignness and Jean-Luc Nancy's idea of being-with is explored. Understanding the complex network of relations in which an entity exists leads to an awareness of its ambiguous nature. To facilitate judgment with such ambiguity, one needs a contextual understanding of a situation.

Cette présente recherche vise à défendre le point de vue selon lequel le don de l’Esprit dans le récit de la Pentecôte (Ac 2, 1-13) s’interprète principalement comme l’investissement d’une puissance habilitant au témoignage. À cette fin, nous posons l’hypothèse que le contenu d’Ac 2, 17-21 est un axe fondamental de la théologie pneumatique de l’œuvre lucanienne, lequel interprète la manifestation pentecostale dans une perspective prophétique. La démonstration se fait par le biais d’une analyse rédactionnelle d’Ac 2, 17-21, une citation de Jl 3,1-5 insérée dans un discours explicatif de Pierre du phénomène pentecostal. Nous examinons d’abord le lieu d’inscription de ce passage dans l’œuvre lucanienne afin d’évaluer la valeur stratégique de son emplacement (chapitre 1). Nous étudions ensuite l’interprétation que fait Luc de cette prophétie pour en venir à la conclusion qu’il envisage l’intervention de l’Esprit essentiellement dans une perspective d’habilitation à la prophétie (chapitre 2). Nous vérifions cette première conclusion dans l’Évangile de Luc (chapitre 3); puis ensuite dans les Actes des Apôtres (chapitre 4). Nous en arrivons ainsi à établir un parallélisme entre les étapes initiatiques du ministère de Jésus dans le troisième évangile et celui des disciples dans les Actes, pour y découvrir que, dans les deux cas, l’effusion de l’Esprit habilite à l’activité prophétique. Le ministère des disciples s’inscrit de la sorte dans le prolongement de celui du Maître. Nous soutenons, en fait, que tout le discours pneumatique de l’Évangile de Luc converge vers l’effusion initiale de l’Esprit sur les disciples dans le récit pentecostal, d’une part, et que cette effusion jette un éclairage sur l’ensemble de l’œuvre missionnaire des Actes, d’autre part. Bref, le passage explicatif du phénomène pentecostal, en l’occurrence Ac 2, 17-21, met en lumière un axe central des perspectives de Luc sur l’Esprit : Il s’agit de l’Esprit de prophétie. Dans cette optique, l’effusion de l’Esprit à la Pentecôte s’interpréterait essentiellement comme l’investissement du croyant d’une puissance en vue du témoignage. / This present research argues that the gift of the Spirit in the Pentecost account (Ac 2.1-13) is to be understood as a source of empowerment for the task of witnessing. The thesis that I defend is that the passage of Ac 2.17-21 is in fact a fundamental axis of the pneumatic theology of Luke’s work, which in turn interprets the pentecostal gift as a prophetic endowment. I will demonstrate this affirmation by performing a redactional analysis of Ac 2.17-21, which is, in fact, a citation from Jl 3.1-5 quoted in Peter’s pentecostal speech whose purpose is to interpret the pneumatic phenomenon of Ac 2.1-13. I start by examining the specific position of Ac 2.17-21 in order to assess the strategic value of its location (chapter 1). I will then carefully look at how Luke interprets this prophecy, only to conclude that he understands the work of the Spirit mainly as a source of empowerment for a prophetic task (chapter 2). I will verify this conclusion throughout the Gospel of Luke (chapter 3), and then in the Acts of the Apostles (chapter 4). This exercise will bring to light an important parallel between the circumstances surrounding the inauguration of Jesus’ ministry in the Gospel of Luke and that of the disciples in Acts, which shows that, in both cases, the Spirit is given as a source of power for a prophetic ministry. The disciples’ ministry is therefore to be understood to lie in the continuity of the one of the Master. Consequently, we will see that all of the pneumatic discourse of Luke’s Gospel converges towards the initial outpouring of the Spirit on the disciples in the Pentecost account, and that this same passage subsequently sheds light on the missionary work in Acts. In short, the interpretative passage of the pentecostal phenomenon, Ac 2.17-21, brings to light a fundamental axis of Luke’s perspectives on the Sprit; It is the prophetic Spirit. The gift of Spirit at Pentecost is then in turn to be understood primarily as a prophetic endowment enabling the disciples to witness.

Si la théologie lucanienne de la résurrection a largement été étudiée dans le livre des Actes des Apôtres, Jésus n’a jamais été considéré comme personnage principal, à l’inverse des apôtres, de l’Esprit saint ou même de Dieu. Pourtant, le premier verset des Actes laisse entendre que Jésus va continuer de faire et d’enseigner ce qu’il avait commencé dans l’évangile, même si, peu de temps après l’ouverture du récit, il quitte la scène. Pour chercher à comprendre ce paradoxe, une analyse approfondie de la mise en récit du personnage Jésus dans les Actes était nécessaire. Le premier chapitre de cette thèse introduit le sujet, l’état de la question et deux approches méthodologiques empruntées aux experts de la caractérisation narrative. Au chapitre deux, après avoir introduit la difficulté d’identification du personnage qui se trouve derrière le titre Seigneur des Actes, le cadre épistémologique d’Elizabeth Struthers Malbon permet d’observer le comment en classant toutes les péricopes qui participent à la rhétorique de la caractérisation christologique en cinq catégories : (1) la christologie représentée qui montre ce que Jésus fait, (2) la christologie détournée qui permet d’entendre ce que Jésus dit en réponse aux autres personnages, (3) la christologie projetée qui laisse entendre ce que les autres personnages ou le narrateur disent à Jésus et à son sujet, (4) la christologie réfléchie qui montre ce que les autres personnages font en reflétant ce que Jésus a dit et (5) la christologie reflétée qui montre ce que les autres personnages font en reflétant ce que Jésus a fait. Ensuite, avec le chapitre trois, l’approche de John Darr donne à comprendre le pourquoi de la caractérisation par l’observation de quatre activités cognitives du lecteur : (1) l’anticipation et la rétrospection, (2) la recherche de cohérence, (3) l’identification et/ou l’implication et (4) la défamiliarisation. Enfin, au chapitre quatre, les résultats des deux méthodes sont comparés pour proposer une solution au cas de l’ouverture paradoxale des Actes. D’abord les différentes observations de la thèse montrent que le personnage Jésus n’est pas si absent du récit; puis la rhétorique narrative de la caractérisation conduit le lecteur à comprendre que c’est essentiellement au travers des personnages du récit que Jésus est présent en actes et en paroles. / Though Luke’s theology of resurrection is widely studied in the Book of Acts, Jesus is never seen as its main character, unlike the apostles, the Holy Spirit or God. However, the first verse of Acts suggests that the Jesus character will continue to do and teach what he began in the Gospel, even if soon after the opening, he leaves the scene. To resolve this paradox, a thorough analysis of Jesus characterization in Acts is needed. The first chapter of this dissertation introduces the subject, what has already been said, and two narrative scholars’ methodologies selected for this study. In chapter two, the difficult identification of the Lord of Acts is discussed. Then, the epistemological framework of Elizabeth Struthers Malbon is considered. It shows how characterization works, by ranking all episodes involving Jesus in five groups : (1) enacted Christology : what Jesus does; (2) deflected Christology : what Jesus says in response to other characters; (3) projected Christology : what other characters and the narrator say to and about Jesus; (4) mirroring Christology : what other characters do that mirrors what Jesus says and (5) reflected Christology : what other characters do that mirrors what Jesus does. Chapter three discusses the method of John Darr which helps us to understand the why by observing four cognitive activities of the reader: (1) anticipation and retrospection; (2) consistency-building; (3) identification and (4) defamiliarization. In the conclusion in chapter four, the results of the two systems are compared to resolve the case of the paradoxical opening of Acts. The main conclusion of the different observations of this thesis shows that Jesus is not so absent from the story. Thus the narrative rhetoric of characterization leads the reader to understand that Jesus is mainly present through the characters of the story in acts and words.
