Bystander Narratives: The Fiction of J.M. Coetzee and the Holocaust

SMITH, CRAIG MITCHELL 30 September 2011 (has links)
J.M. Coetzee’s novels are suffused with a pervasive, though often oblique, Holocaust awareness. Direct references to the event and to the historical era to which it belongs, subtle stylistic and thematic echoes of Holocaust writing, and the recurrent mobilization of Holocaust imagery in Coetzee’s novels all contribute to suggest the significance of the event to the author’s work and thought. Providing Coetzee with a lens through which to view the contemporary situation, both local and global, the Holocaust offers Coetzee a means by which difficult and complex questions of ethics and historiographical truth may be approached. Above all, the Holocaust and its representation contribute to Coetzee’s exploration of the dilemmas of translating the traumatic lived experience of atrocity – including, but not limited to, life in apartheid South Africa – into narrative form. Taken as a whole, Coetzee’s oeuvre initially anticipates and later responds to, in characteristically oblique fashion, the narrative project(s) facing post-apartheid South Africa as the newly-democratic nation sought to make sense of its past through a variety of means, the most important of which was the country’s Truth and Reconciliation Commission. Implicitly challenging the TRC’s findings as well as its narrative assumptions, the Coetzean oeuvre accordingly invites being read as offering a continuous and evolving counter-narrative to the TRC and its construction of a narrative of the apartheid past for the post-apartheid nation. In utilizing the Holocaust, its representations, and the reception thereof to frame his response to apartheid, Coetzee implicates both in a critique of the Western model of modernity, suggesting, in the process, the importance of reconfiguring modernity in a more ethical shape. / Thesis (Ph.D, English) -- Queen's University, 2011-09-29 12:15:58.377

Approche théorico-expérimentale du comportement de panneaux sandwichs à parements composites textile-mortier dans le cadre de la construction durable / -

Junes, Angel 09 July 2014 (has links)
Cette étude concerne la conception de structures dans le cadre des nouveaux critères de développement durable et d'hygiène et sécurité via la valorisation des matériaux à empreinte écologique réduite et favorisant les économies d'énergie. Les travaux de thèse portent sur l'étude théorico expérimentale de panneaux sandwich mettant à profit des composites textile-mortier TRC (Textile Reinforced Concrete) de dernière génération. Il s'agit plus précisément du développement d'une modélisation du comportement mécanique de panneaux sandwich intégrant une approche analytique-numérique innovante et de prévision du comportement de panneaux sandwich intégrant les non-linéarités matérielles et compatibles avec des schémas de chargement complexes. Sur la base d'un ancrage expérimental conséquent, tant au niveau du matériau qu'à l'échelle du composant de structure, il a été possible de valider le modèle par la considération de plusieurs critères tels que l'analyse du comportement global (charge-flèche) mais aussi de la faculté de restituer les déformations et modes d'endommagement et de rupture. Enfin, en se fondant sur l'identification expérimentale des propriétés mécaniques vieillies des éléments constitutifs du panneau sandwich, via une procédure de vieillissement accéléré, des simulations, reposant sur le modèle préalablement valide, ont été entreprises pour évaluer l'incidence sur le comportement et les mécanismes d'endommagement de l'élément de structure considéré. Il a été possible de mettre en évidence la probabilité de la modification des modes de rupture assortie de pertes sensibles des propriétés globales tels que la rigidité initiale et la capacité portante. Ces résultats devront faire l'objet à terme de validation sur des panneaux vieillis mais sont susceptibles d'éclairer les démarches de dimensionnement / This work fits in the context of the structural design under new sustainable development, health and safety criteria through material recovery to reduced environmental damage and promoting energy savings. This thesis focuses on the theoretical and experimental study of sandwich panels taking advantage of new generation textile - cement matrix composites: TRC ( Textile Reinforced Concrete). It is specifically the establishment of an analytical-numerical approach to predict the behavior of sandwich panels incorporating material non-linear behavior and compatible with different and complex loading combinations. Based on an experimental campaign both at the material and structure level, it was possible to validate the model by several criteria such as the ability approximate the global behavior (load deflection) but also the ability to reproduce the local deformations and failure modes. Finally, based on the experimental identification of the mechanical properties of aged sandwich panel components, by an accelerated aging procedure, simulations were made based on the previously validated model to assess the impact on the behavior and damage mechanisms of the studied structural element. It was possible to demonstrate the probability of the failure mode change accompanied with significant losses of the global properties such as the initial stiffness and bearing and deflection capacity. These results will be eventually subject of validation on natural-aged panels but are likely to inform the design approach

Theoretische und experimentelle Untersuchung des spaltungsinduzierten Versagens von TRC Prüfkörpern

Schoene, Jens, Reisgen, Uwe, Schleser, Markus, Jeřábek, Jakub 01 December 2011 (has links) (PDF)
Bewehrungen mit einer hochmoduligen Polymertränkung erreichen im Betonbauteil Textilspannungen von über 1200 N/mm². Ab diesem Niveau wurden in Dehnkörperversuchen Längsrisse und Betonabplatzungen beobachtet. Für die Eingrenzung und Identifikation der elementaren, verantwortlichen Mechanismen weisen großformatige Dehnkörper störende Einflüsse von Randeffekten und Imperfektionen auf. Daher wurde ein neuer Versuchsaufbau entwickelt, bestehend aus einem in einen Betonquader eingebetteten Einzelroving. Die simple Herstellung und die Verlässlichkeit dieser Kategorie von Experimenten in Bezug auf die Reproduzierbarkeit und der geringen Streuung der Resultate machen sie zu einer robusten Grundlage für experimentelle Untersuchungen des Verhaltens von TRC. Die experimentell ermittelten Bruchlasten werden zunächst bezüglich ihrer Leistung diskutiert und dann die beobachteten Bruchvorgänge kategorisiert hinsichtlich kompatibler mechanischer Hypothesen für die Initiierung von Längsrissen und des Spaltversagen. / Reinforcements with a high-modulus, polymeric impregnation achieve textile tensions of 1200 N/mm² and more in concrete parts. Starting at this level longitudinal cracks and splitting were observed in tests. In order to isolate and identify the fundamental, responsible mechanisms large-scale specimen show an interfering impact of boundary effects and imperfections. Therefore a new test set-up was developed, consisting of a single roving embedded in a single concrete cuboid. The simplicity of production and reliability of this class of experiments in terms of repeatability and low scatter of results makes them a robust basis for experimental investigation of TRC behavior. The experimentally obtained strengths are discussed in terms of the performance, followed by the categorization of observed failure patterns with respect to the available mechanical hypotheses of the longitudinal crack initiation and splitting failure.

Pultruded Textile Reinforced Concrete Structural Sections

January 2017 (has links)
abstract: Pultrusion manufacturing technique stands at the forefront for efficient production of continuous, uniform concrete composites for use in large scale structural applications. High volume and low labor, among other benefits such as improved impregnation and better sample consistency, stand as some of the crucial advances found in automated pultrusion. These advantages introduce textile reinforced concrete (TRC) composites as a potential surrogate for wood, light gauge steel, and other common structural materials into an ever changing and broadening market of industrial grade structural sections. With the potential modifications of textile geometry, textile type, section geometry, and connection type, the options presented by TRC sections seem nearly boundless. Automated pultrusion presents the ability to manufacture many different TRC composite types in at a quickened rate opening up a new field of study of structural materials. The objective of this study centered on two studies including the development of an automated pultrusion system for the manufacturing of TRC composites and ultimately the assessment of composites created with the pultrusion technique and their viability as a relevant structural construction material. Upon planning, fabrication, and continued use of an automated pultrusion system in Arizona State University’s Structures Lab, an initial, comparative study of polypropylene microfiber composites was conducted to assess fiber reinforced concrete composites, manufactured with Filament Winding Technique, and textile reinforced concrete composites, manufactured with Automated Pultrusion Technique, in tensile and flexural mechanical response at similar reinforcement dosages. A secondary study was then conducted to measure the mechanical behavior of carbon, polypropylene, and alkali-resistant glass TRC composites and explore the response of full scale TRC structural shapes, including angle and channel sections. Finally, a study was conducted on the connection type for large scale TRC composite structural sections in tension and compression testing. / Dissertation/Thesis / Masters Thesis Civil Engineering 2017

Indigenous Worldviews: Teachers’ Experience with Native Studies in Ontario

Lagarde, Natasha 10 July 2018 (has links)
This research is an analysis of Ontario teachers’ experiences with Grade 11 NDA3M Current Aboriginal Context in Canada curriculum. By deconstructing and critically analyzing the curricular and pedagogical implications, my thesis is a targeted response to number 63 of the Truth and Reconciliation Calls to Action. As outlined by Clandinin and Connelly (2000), this research is centred in narrative research techniques. Additionally, I draw on Miller’s (1996) 3L’s: Look, Listen, and Learn approach, paired with Dion and Dion’s (2004) storytelling as a means of telling and (re)telling the story. I used one-on-one interviews with teachers and one sharing circle with teachers and elders to synthesize data from documents to capture the essence of the lived experiences. Participants revealed their experiences of what Aoki claims is curriculum-as-planned and curriculum-as-lived in this course. The results of this research were revealed responses to components of number 63 of the Calls to Action; NDA3M requires a review of curriculum expectations to align with teachers’ classroom experiences; participants discussed how their respective schools are using every opportunity to students’ capacity and awareness of Indigenous Worldviews; and professional development to support Indigenous education is in high demand.

Has the failure to conduct post-Truth and Reconciliation Commission prosecutions in South Africa contributed to a culture of impunity for economic crimes?

Mabunda, Sagwadi January 2015 (has links)
Magister Legum - LLM / The end of Apartheid and the transition to a new constitutional democracy in South Africa was ushered in by the Truth and Reconciliation Commission (TRC). The purpose of the TRC was to promote a dialogue between victims and perpetrators of gross human rights violations to try and achieve reconciliation in the country. To this end, the TRC was given the power to grant conditional amnesty to those who came forward to reveal the full truth to the country about the crimes that they had committed. Those who refused to apply for amnesty or who did apply but were denied amnesty were supposed to be prosecuted. A number of years have passed since the final TRC report was submitted and hardly any prosecutions have taken place. This paper argues, by comparing the transitions in Argentina and Chile to the one in South Africa, that the lack of post-Truth Commission prosecutions in South Africa has contributed to nurturing a culture of impunity for acts of corruption in high offices of state. It argues that in countries transitioning from repressive and authoritarian regimes to democratic governments, prosecutions of gross human rights violations are necessary for the creation and strengthening of the rule of law and a human rights culture. Therefore, the impunity for economic crimes such as corruption is detrimental to democracy.

Reconciliation in Southern Africa : the role of the Afrikaans Churches. A historical and analytical study of the contributions of the Afrikaans Churches to the process of reconciliation in Southern Africa, with special reference to their response to the work of the Truth and Reconciliation Commission

Els, Cornelius Wilhelmus 23 October 2008 (has links)
This study investigates the role of the Afrikaans Churches in the quest for reconciliation in South Africa. Since it is a historical and analytical study, much use has been made of the relevant historical material. It is important in a study like this that there be a relevancy for this kind of study. South Africa is a nation with a complex society, who were weighed down for about forty years under an Apartheid policy, necessitating a probe into the influence of apartheid on society at large but also on the Afrikaans Churches. The different cultural groups in our country need to be reconciled to each other. But what kind of reconciliation? Many different definitions of reconciliation are given depending on who defines it. The politicians’ definitions were different from that of the church. Because reconciliation is a biblical term, it is necessary to look at the biblical mandate and how reconciliation is defined in biblical terms. Short overviews of the history of the origin of the different Afrikaans Churches under discussion are given. (Chapter 1) In order to understand the reaction of the different churches to the announcement of the constitution of a Truth and Reconciliation Commission (TRC), it is necessary to look at those events that happened in the churches during the years of Apartheid. The fact that the Dutch Reformed Church (DRC) is the largest church under the Afrikaners, explains why more space is given to occurrences in the DRC than to the others. Because Afrikaners work together in many situations, belong to the same clubs, etc. it is also clear that the occurrences in the DRC would have some effect on members of the other churches. Attention is paid to the polarisation and tension amongst churches due to race relations as it manifested itself within South Africa and also globally. (Chapter 2) Through Parliamentary legislation, a Truth and Reconciliation Commission was established for South Africa. It is important to take note of the mandate of the TRC and its method of work. Different reactions came from the faith communities and especially from the Afrikaans Churches. This researcher investigates the different attitudes in the churches as made known through correspondence in the different church magazines and daily newspapers. Attention is paid to the different reactions of the churches to the special hearings and the question whether churches must confess before the TRC or not. (Chapter 3) The reactions in the churches on the submission of evidence before the TRC are investigated. Only the DRC and the Apostolic Faith Mission (AFM) of the Afrikaans Churches and four theologians from the Reformed Churches of South Africa (RCSA) made their submissions. The other churches did not make use of this opportunity to clear their slates. The submission of the Uniting Reformed Church of South Africa (URCSA)is also mentioned as many of its members are Afrikaans speaking. (Chapter 4 ) The TRC suggested some proposals on reconciliation for the faith communities. This chapter looks at the responses of the churches to these proposals. There are wonderful things happening where churches were obedient and involved in their surroundings. Mostly they are helping in the areas of poverty relief and unemployment. The question about unity between the ‘sister’ churches amongst the Afrikaners and unification between the DRC and URSCA is discussed. (Chapter 5) Is there hope for our country for reconciliation? This question was addressed to a few leaders in the different churches and their responses are given. Churches do not always know how to go about helping their congregants working on reconciliation. Three models are currently being presented in South Africa on how reconciliation can become a reality and are briefly discussed. A new model is then worked out and proffered for use in and by the church to help congregants in the quest for reconciliation. (Chapter 6) Chapter 7 concludes this study by proposing a few conclusions. An extensive Addendum is given. This researcher interviewed church leaders. Their responses and other relevant material e.g. submissions by churches etc. to the TRC are given. A bibliography concludes this dissertation. / Thesis (PhD)--University of Pretoria, 2008. / Science of Religion and Missiology / unrestricted

Amnesty as a tool of transitional justice : the South African Truth and Reconciliation Commission in profile

Daniel, Kobina Egyir January 2001 (has links)
"This dissertation seeks firstly to re-examine the merits of the competing philosophies on the role of amnesties in transitional justice. It seeks in particular to investigate the currently popular notion that justice is necessarily retributive and even beyond that, to determine the veracity of the claim that prosecution represents a necessary element of retributivist justice. The objective is to contribute to the ongoing debate by examining and drawing practical lessons from the case of South Africa, which emerged in 1994 from several generations of institutionalised gross violatoins of human rights. Accordingly the Amnesty Committee of the South African Truth and Reconciliation Commission (TRC), the law and the political philosophy undergirding its functions represent the focus of this study. ... This dissertation unfolds into five parts. Chapter 1, as an introduction to the rest of the work, sets out the relevance of the subject under review, the methodology and a brief overview of the chapters. Chapter two reviews the extensive literature on transitional justice and discusses the concepts that may be distilled therefrom. It discusses the contextual determinants of models of transitional justice and sets out the essence of the debate between vengeance and forgiveness as tools for achieving transitional justice. It also discusses the development of international law with respect to the permissiveness of amnesties and both the articulated and other justifications for their use. The burden of the third chapter is to first recount the factual circumstances of South Africa's trnsition and the factors that predicated the promulgation of the Promotion of National Unity and Reconciliation Act 34 of 1995. It then briefly examines the provisions of the statute and it's implementation. It also engages in an empirical assessment of the almost 800 amnesties granted and employs a number of indices to determine whteher the process was even handed and achieved its objectives. These indices are: the politicl affiliations of the awardees; whether or not the crimes for which they received amnesty involved the loss of life; whether or not they had already been punished for thier transgressions and; whether or not they received forgiveness from the vicitms - actual or constructive. Chapter four focuses on some fo the criticisms that the TRC received. It assesses their merits and determines to what extent they subverted the quest for justice in transitional South Africa. In particular it looks at the reasoning of the Constitutional Court in the AZAPO Case, the alleged lack of objectivity of the TRC, its almost exclusively Christian orientation and its almost exclusive focus on abuses of civil and political rights. Chapter five concludes the dissertation by first determining whether or not there are any lessons to be learnt from South Africa's amnesty experience. It then outlines what the lessons are or should be. It closes by making recommendations as to what factors or particular considerations should guide the efforts and aspirations of abused societies that embark on the quest for transitional justice." -- Chapter 1. / Prepared under the supervision of Professor Frans Viljoen, Faculty of Law, University of Pretoria, South Africa / Thesis (LLM (Human Rights and Democratisation in Africa)) -- University of Pretoria, 2001. / http://www.chr.up.ac.za/academic_pro/llm1/dissertations.html / Centre for Human Rights / LLM

Renforcement des structures historiques en maçonnerie par matériaux composites : application aux murs en pierres calcaires / Strengthening of historic masonry structures with composite materials : application to the walls of limestone

Gharib, Turath 06 July 2015 (has links)
Ce travail concerne l’étude du renforcement de structures en pierres par matériaux composites. Deux techniques de renforcement sont utilisées. L’un s’agit de renforcement par matrice cimentaire renforcé avec de textile de fibre de verre TRC. L’autre est renforcement par barres de fibre de verre de FRP suivant la technique de NSM (near-surface mounted). La première phase consiste en la caractérisation des matériaux et l’analyse des comportements mécaniques en compression en cisaillement et en traction de petits éléments de maçonnerie composées d’un assemblage de pierre et mortier bâtard. Les valeurs caractéristiques du comportement mécanique de la maçonnerie sont comparées avec les différents modèles dans la littérature qui calculent les paramètres caractéristiques avec une bonne approximation avec les résultats expérimentales. En plus, le comportement de matériaux de renforcement sont testés en traction ainsi que le comportement de l’adhésion entre le renfort et la maçonnerie est étudié. La deuxième phase se concentre sur le renforcement de murs de maçonnerie soumis sur deux types de chargement. L’un s’agit de cisaillement dans le plan des murs effectué avec l’essai de compression diagonale. Le deuxième représente des charges de flexion à 3 points hors plan des murs accompagné par des forces de compression axiale qui provoque une contrainte de compression de 0.2 MPa. L’essai de cisaillement s’est réalisé sur des murs carrés de cinq rangées de pierres avec mortier. Le renforcement par deux barres verticales de NSM FRP améliore significativement la ductilité et le module de cisaillement des murs, ainsi que le renforcement avec deux couches orthogonales de TRC améliore la résistance au cisaillement. Enfin l’application de modèles analytiques a permet de comparer les résultats expérimentaux aux résultats donnés avec les modèles. En plus, l’essai de flexion à 3 points est effectué sur des murs composés de douze rangées de pierres avec mortier. Le renforcement avec deux barres verticales et deux barres transversales a plus augmenté la rigidité élastique. En revanche, le renforcement avec TRC composé d’une seule couche de textile accompagné avec une barre verticale de FRP n’augmente pas la résistance de mur par rapport à la résistance du mur renforcé avec une seule couche de textile ou avec une barre verticale seule / This work concerns the study of the reinforcement of stone structures with composite materials. Two reinforcing techniques are used. One is reinforcement by cement matrix reinforced with textile TRC of glass fiber. The other is by reinforcing FRP fiberglass rods according to NSM technique (near-surface mounted). The first phase consists of materials characterization and analysis of mechanical behavior in compression shear and tensile of small masonry specimens made of stone and mortar. The characteristic values of the mechanical behavior of the masonry are compared with the different models in the literature which calculate the characteristic parameters and give a good approximation with the experimental results. In addition, the behavior of reinforced materials is tested in tension and the behavior of the adhesion between the reinforcement and the masonry is studied. The second phase focuses on strengthening masonry walls subjected to two types of loading. One is in-plane shear of walls made with the diagonal compression test. Represents the second bending loads to 3 points out of plane walls accompanied by axial compression forces which cause a compressive stress of 0.2 MPa. The shear test was performed on square walls of five rows of stones with mortar. Strengthening by two vertical bars NSM FRP significantly improves the ductility and shear modulus of the walls and the reinforcement with two orthogonal layers TRC improves shear strength. Finally the application of analytical models used to compare the experimental results with the results given by the models. In addition, the bending test with 3-point is carried out on walls composed of twelve rows of stones with mortar. The reinforcement with two vertical bars and two crossbars increased more elastic stiffness. However, the reinforcement with TRC composed of a single layer of textile accompanied with a vertical bar FRP does not increase the resistance of the wall relative to the resistance of the reinforced wall with a single layer of textile or with a simple vertical bar
