Profaning the Sacred and Sacralising the Profane: Transforming Objects and Bodies in Elie Wiesel’s Night and A. M. Klein’s The Second Scroll

Wilson, Lucas F. 10 1900 (has links)
<p>This thesis seeks to interrogate how Elie Wiesel’s <em>Night</em> and A. M. Klein’s <em>The Second Scroll</em> illustrate the spiritual journeys of their protagonists and depict dehumanization of the Jewish people. Through their interactions with sacred bodies, as well as profane, religious and sacred objects, both novels map the spiritual quests of the protagonists, revealing very different conclusions. Using Virginia Greene’s “‘Accessories of Holiness’: Defining Jewish Sacred Objects” as an analytic framework, I explore how both novels transform sacred bodies into profane “objects” to illustrate various forms of anti-Semitic subjugation and de-personification. I then interrogate how <em>The Second Scroll</em> “textualizes” these objectified bodies, as well as how Klein’s novel turns Israeli society into a sacred text. This “textualization” offers a space to re-affirm God’s providence in a post-Holocaust imagination—an imagination that strongly differs from the rejection of God in <em>Night</em>. Through this exploration of spirituality and dehumanization, both texts humanize those who have been dehumanized in the camps and re-face the victims whose personhood was stripped from them, inviting them to dwell in both the novels and the readers’ memory.</p> / Master of English

The implications of the out of field phenomenon for school management

Du Plessis, Anna Elizabeth 30 November 2005 (has links)
The out of field phenomenon, that is, educators who teach outside their field of expertise, adds complexity to the education environment. This growing phenomenon in South African schools impacts colleagues, learners, parents, governing bodies and school management. Teaching characteristics that ensure success in classrooms are threatened by the out of field phenomenon. It puts extra strain on school management's responsibility to provide quality management and jeopardises effective teaching and quality learning. This problem was investigated by a literature study and an empirical investigation using a qualitative approach. Data was gathered through semi-structured interviews with selected participants who shared their experiences of the phenomenon. Findings indicated that the existence of the out of field phenomenon should be recognised in order to provide substantial educator support and sufficient staff development programmes. It is recommended that new evidence-informed knowledge about the out of field phenomenon can contribute to improve effective decision making and policy developing in this regard. / Education management / M.Ed.

The ancient Narratio as an ecclesial participation in the divine pedagogy: a study of its sources and proposal for its current application

Innerst, Sean 11 1900 (has links)
This study represents a work of practical narrative theology which originates in the notable prominence of an ancient form of catechesis in a modern document, the General Directory for Catechesis (GDC), issued in 1997 by the Sacred Congregation for the Clergy in the Vatican. The GDC first mentions narratio explicitly in number 39 in the form of an imperative: "Catechesis, for its part, transmits the words and deeds of Revelation; it is obliged to proclaim and narrate them and, at the same time, to make clear the profound mysteries that they contain." It is under the weight of that obligation that this study came to be. Narratio, or the narration of salvation history, which was a standard part of the catechesis of the Church of the fourth and fifth centuries gave way to the exigencies of a changing Church in which the catechetical focus turned from adults, who needed a Judeo-Christian worldview to replace a Greco-Roman one, to children who had grown up in communities shaped by a Christian vision. This doctoral thesis proceeds by, first, surveying Roman Catholic magisterial teaching immediately preceding the issuance of the GDC to trace the roots of this apparent innovation within an institution which is otherwise noted for its conservatism. After establishing the context and character of the GDCs call for revival of narratio, this thesis examines the historical setting, rhetorical structure, and function of narratio in Augustine of Hippo's De catechizandis rudibus, and then its scriptural precursors in the two Testaments in order to discover how this narration functioned in the Jewish and Christian communities which practiced haggadic and anamnetic recitals of God's saving works as a means to the formation and maintenance of communal identity. This study seeks to establish that a positive response to the GDC's call is as much warranted by the evidence provided in the biblical and post-biblical Jewish and Christian practice of ritual/covenantal remembrance as by the Catholic magisterial imperative in the GDC. In this, it may aid to inform and direct such a positive response to the GDC for the revival of the catechetical narratio. / Christian Spirituality, Church History and Missiology / D. Th.

A management model for the recognition of prior learning (RPL) at the university of South Africa

Janakk, Lisa 11 1900 (has links)
This study explored the implementation of the recognition of prior learning (RPL) at Unisa by investigating the strengths and weaknesses of the RPL methodology, instruments and processes when taking students through the RPL process. The successes and challenges experienced by the RPL academic advisors and the academic assessors were determined and guidelines provided for the effective implementation of RPL at Unisa. The empirical research design was exploratory within a qualitative framework employing participant observation, focus group interviewing, individual interviewing and the distribution of questionnaires that consisted of open-ended questions. The research sample comprised 26 purposefully selected participants. With regard to the research findings, the challenges include a lack of administrative support, a lack of support from top management and the academic staff, and a lack of communication between management and the RPL department. The strength of the RPL department lay in its well-documented process manual. / Teacher Education / M. Ed. (Education Management)

No. of bitstreams: 1 dissertacao_augustro_cesar_pimentel.pdf: 3594051 bytes, checksum: 1bab2fcda8325cb19fa869b9cd34cd41 (MD5) Previous issue date: 2008-12-19 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This work consists in a historical-cultural research of construction of a Plaza with a monument in homage to Mathematics, it was idealized by a visionary mayor, 29 years old, in a city called Itaocara, interior of the State of Rio de Janeiro, in 1943. What is now a touristic attraction arose from the creativity of a young politician. Although he was a lawyer, he saw in mathematics his source of pleasure. To write this research, there was an interview with the mayor of that time, currently with 94 years old, with the inhabitants, and the daughter of the constructor of the square, in addition, the examination of documents, historical photos, and similar stuffs. The director of the project was the mathematician Malba Tahan (pseudonym of Júlio César de Mello e Souza) organized a selecting process with his students of the National School of Fine Arts of the University of Brazil, today Federal University of Rio de Janeiro (UFRJ). The winner was Mr. Godofredo Formenti. The Square was built by Mr. Italarico Alves, a citizen of Itaocara and the single official builder of the town and despite his low education, he made a geometrically perfect work, under the coordination of Malba Tahan, resulting in the unique monument in the world, capable of highlighting the poetic power of the mathematics art in the process of re-inventing the socio-historical-cultural of a countryside community, which concretizes its pride in the maxim that "who knows does the time, do not wait it to occur / O presente trabalho consiste na investigação histórico-cultural da construção de uma praça, com um monumento em homenagem à Matemática, idealizado por um prefeito visionário, de 29 anos, na cidade de Itaocara, interior do Estado do Rio de Janeiro, no ano de 1943. O que é hoje uma atração turística, surgiu da criatividade do jovem político que apesar de advogado, via na matemática sua fonte de prazer. Para essa pesquisa, realizou-se entrevistas com o próprio prefeito da época, atualmente com 94 anos, com moradores antigos e com a filha do construtor da praça, além de análise de documentos, fotografias, históricos e afins. O diretor do projeto foi o matemático Malba Tahan (pseudônimo de Júlio César de Mello e Souza), que realizou um concurso com seus alunos da Escola Nacional de Belas Artes da Universidade do Brasil, hoje, Universidade Federal do Rio de Janeiro (UFRJ), sendo vencedor o Sr. Godofredo Formenti. A Praça foi construída pelo Sr. Italarico Alves, morador de Itaocara e único construtor oficial da cidade e que apesar da pouca escolaridade, realizou um trabalho geometricamente perfeito, sob a coordenação de Malba Tahan, resultando em um monumento único no mundo, capaz de ressaltar o poder poético da arte matemática no processo de reinvenção sócio-histórico-cultural de uma comunidade interiorana, que concretiza seu orgulho na máxima de que quem sabe faz a hora não espera acontecer

Re-Imagining the Victorian Classics: Postcolonial Feminist Rewritings of Emily Brontë

Celestrin, Yannel 27 March 2018 (has links)
ABSTRACT OF THE THESIS RE-IMAGINING THE VICTORIAN CLASSICS: POSTCOLONIAL FEMINIST REWRITINGS OF EMILY BRONTË by Yannel M. Celestrin Florida International University, 2018 Miami, Florida Professor Martha Schoolman, Major Professor Through a post-structural lens, I will focus on the Caribbean, specifically Cuba, Guadeloupe, Marie-Galante, and Roseau, and how the history of colonialism impacted these islands. As the primary text of my thesis begins during the Cuban War of Independence of the 1890s, I will use this timeframe as the starting point of my analysis. In my thesis, I will compare Emily Brontë’s Wuthering Heightsand Maryse Condé’s Windward Heights. Specifically, I will examine Condé’s processes of reimagining and rewriting Brontë’s narrative by deconstructing the notions of history, race, gender, and class. I will also explore ways in which Condé disrupts the hegemonic and linear notions of narrative temporality in an attempt to unsilence the voices of colonized subjects. I argue that Condé’s work is a significant contribution to the practice of rewriting as well as to the canon of Caribbean literary history. I argue that the very process of rewriting is a powerful mode of resistance against colonizing powers and hegemonic discourse.

Temperiertes Innenhochdruck-Umformen von Rohren aus Magnesium- und Aluminiumlegierungen

Seifert, Michael 25 November 2008 (has links) (PDF)
Die Anwendungsmöglichkeiten und Potenziale des temperierten Innenhochdruck-Umformens mit flüssigen Wirkmedien (T-IHU) von Rohren aus verschiedenen Magnesium- und Aluminiumknetlegierungen werden in der vorliegenden Arbeit aufgezeigt. Neben der Werkstoff- und Halbzeugcharakterisierung, der Auslegung von temperierten Innenhochdruck-Umformanlagen und –werkzeugen, den Thermografiemessungen am Halbzeug unter Realbedingungen und der Verifizierung der Simulationsergebnisse des T-IHU-Werkzeuges war der inhaltliche Schwerpunkt die systematische experimentelle Bestimmung der maximalen Umfangserweiterung ∆u<sub>max</sub> in Anhängigkeit von der Umformtemperatur ϑ<sub>u</sub>, dem Werkstoff und der Wanddicke s<sub>0</sub> im Temperaturbereich von 22°C bis 300°C an drei Versuchsgeometrien T-Stück, Zylinder und Quader bei Innendrücken bis 800 bar. Neben dem Einfluss der Prozessparameter, der Werkstoff- und Halbzeugeigenschaften und der Ausgangswanddicke wurde der signifikante Einfluss der Umformtemperatur und der Umformgeometrie auf die erreichbaren Umfangserweiterungen herausgearbeitet und systematisch dargestellt. Es wurden Umfangsdehnungen von bis zu 120 % (bei ϑ<sub>u</sub> = 300°C) erzielt. Die experimentelle Bestimmung der minimal auszuformenden Bauteilaußenradien erfolgte unter Anwendung der statistischen Versuchsplanung. Aus den Regressionsgleichungen wurde eine neue Berechnungsgleichung für den maximalen Innendruck p<sub>imax</sub> generiert. Durch die Verifikation dieser Gleichung konnte die hohe Genauigkeit bei der Vorausberechnung des erforderlichen Innendruckes bei einem vorgegebenen minimalen Bauteilaußenradius R<sub>min</sub> in Abhängigkeit von der Zugfestigkeit R<sub>m</sub> als f (Umformtemperatur) und der Wanddicke s<sub>0</sub> nachgewiesen werden. Die Auslegung der T-IHU-Werkzeug- und Anlagentechnik kann damit wesentlich genauer er­folgen. Durch die Bauteilanalysen nach dem T-IHU-Prozess konnten die hohe Maß- und Formgenauigkeit und die hohe und gleichmäßigere Oberflächengüte nachgewiesen werden. Trotz der beginnenden dynamischen Rekristallisation lag bei allen Versuchswerkstoffen eine Erhöhung der Werkstofffestigkeit in der Umformzone vor. Bei den Untersuchungen bzgl. des T-IHU des Realbauteiles „PKW-Querträger vorn“ konnten die Kenntnisse der Grundlagenuntersuchungen auf ein komplex geformtes Realteil übertragen und erweitert werden. Es zeigte sich, dass der Einsatz von T-IHU-Magnesiumbauteilen ein erhebliches Potenzial für weitere Gewichtsreduzierungen von Leichtbaukonstruktionen besitzt. / This paper presents the potential applications of temperature-supported hydroforming of various magnesium and aluminium alloy tubes using active liquid media. It includes details of material and semi-finished product characterisation, the design of temperature-supported hydroforming equipment and tools, thermography measurements on the semi-finished product under real conditions and verification of simulation results for the temperature-supported hydroforming tool. The main focus, however, was the systematic, experimental approach to determining the maximum increase in perimeter ∆u<sub>max</sub> as a function of the forming temperature ϑ<sub>u</sub>, the material and the wall thickness s<sub>0</sub> in the temperature range 22°C to 300°C for three trial geometries (T‑piece, cylinder and cuboid) at internal pressures of up to 800 bar. In addition to studying the effect of process parameters, material properties, semi-finished product characteristics and initial wall thickness, the paper also presents the finding that forming temperature and forming geometry have a significant impact on achievable increases in perimeter. Perimeter expansions of up to 120 % were attained (at ϑ<sub>u</sub> = 300°C). Statistically designed experiments were used to determine the minimum component outside-radii to undergo the forming process. A new equation for calculating the maximum internal pressure p<sub>imax</sub> was generated from regression equations. By verifying this equation, it was possible to demonstrate the high level of accuracy in predicting the internal pressure required for a given minimum component outside-radius R<sub>min</sub> as a function of the tensile strength R<sub>m</sub> as f(forming temperature) and of the wall thickness s<sub>0</sub>. This means that the temperature-supported hydroforming tool and system equipment can be designed far more accurately. Component analyses after the temperature-supported hydroforming process demonstrated the high level of dimensional and geometrical accuracy and the high quality and more consistent surface finish. Despite the onset of dynamic re-crystallisation, the strength of the material was increased in the forming zone in all the materials tested. The knowledge gained from researching the fundamental principles was applied to a real component with a complex shape in studies of temperature-supported hydroforming of the "front car cross-member", which provided further useful insights. It was found that the use of temperature-supported hydroforming magnesium components has considerable potential for further weight reduction in lightweight constructions.

Professions réglementées et détresse psychologique : regards croisés avec la population en emploi au Canada.

Cadieux, Nathalie 12 1900 (has links)
Cette thèse doctorale poursuit l’objectif de mieux comprendre le rôle joué par la profession réglementée en tant que déterminant de la détresse psychologique de la population en emploi au Québec et au Canada. Ceci, dans un contexte où plusieurs ordres professionnels représentant des professions réglementées, s’inquiètent de la santé mentale de leurs membres et de la pression considérable exercée sur eux dans une économie caractérisée par des pénuries de main-d’oeuvre importantes. Cette thèse fut également inspirée par les nombreuses limites constatées à la suite d’une revue de la littérature sur la santé mentale au travail, alors que les risques différenciés auxquels seraient soumis ces professionnels, comparativement à l’ensemble de la population en emploi, demeurent largement à documenter. La profession réglementée s’associe-t-elle directement à l’expérience de détresse psychologique? Quelles sont les conditions de travail susceptibles de conduire au développement ou à l’aggravation de la détresse psychologique pour ces professions? Dans le but de mieux comprendre le rôle joué par la profession réglementée en matière de détresse psychologique, nous avons eu recours à un modèle théorique multidimensionnel qui postule que les contraintes et les ressources découlent d’un ensemble de structures sociales incluant la profession, le travail, la famille, le réseau social hors-travail et les caractéristiques personnelles. Ce modèle découle des théories micro et macro en sociologie (Alexander et al., 1987; Ritzer, 1996), de l’approche agent-structure(Archer, 1995; Giddens, 1987) ainsi que de la théorie du stress social (Pearlin,1999). Trois hypothèses sont soumises à l’étude à travers ce modèle. La première hypothèse, est à l’effet que la profession réglementée, les conditions de travail, la famille ainsi que le réseau social hors-travail et les caractéristiques individuelles, contribuent directement et conjointement à l’explication du niveau de détresse psychologique. La seconde hypothèse induite par le modèle proposé, pose que le milieu de travail médiatise la relation entre la profession réglementée et le niveau de détresse psychologique. La troisième et dernière hypothèse de recherche, postule enfin que la relation entre le milieu de travail et le niveau de détresse psychologique est modérée par les caractéristiques individuelles ainsi que par la famille et le réseau social hors-travail. Ces hypothèses de recherche furent testées à partir des données longitudinales de l’Enquête nationale sur la santé de la population (ENSP) (cycles 1 à 7). Les résultats obtenus sont présentés sous forme de 3 articles, soumis pour publication, lesquels constituent les chapitres 5 à 7 de cette thèse. Dans l’ensemble, le modèle théorique proposé obtient un soutien empirique important et tend à démontrer que la profession réglementée influence directement les chances de vivre de la détresse psychologique au fil du temps, ainsi que le niveau de détresse psychologique lui-même. Les résultats indiquent que les professions réglementées sont soumises à des risques différenciés en termes de conditions de travail susceptibles de susciter de la détresse psychologique. Notons également que la contribution du milieu de travail et de la profession réglementée s’exerce indépendamment des autres dimensions du modèle (famille, réseau social hors-travail, caractéristiques personnelles). Les résultats corroborent l’importance de considérer plusieurs dimensions de la vie d’un individu dans l’étude de la détresse psychologique et mettent à l’ordre du jour l’importance de développer de nouveaux modèles théoriques, mieux adaptés aux contextes de travail au sein desquels oeuvrent les travailleurs du savoir. Cette thèse conclue sur les implications de ces résultats pour la recherche, et sur les retombées qui en découlent pour le marché du travail ainsi que pour le développement futur du système professionnel québécois et canadien. / This doctoral thesis aims to understand the role played by the regulated occupations as a determinant of psychological distress of the working population in Quebec and Canada. This, in a context where several professional organizations, representing regulated occupations, are concerned about the mental health of their members and the pressure exerted on them in an economy characterized by important shortages of labor. This thesis was also inspired by the many limitations observed after a literature review on work and mental health, whereas the differentiated risks which would be subjected to these professionals, compared to the total working population, remains largely undocumented. Is there a direct link between the regulated occupation and the experience of psychological distress? What working conditions contribute to the development or accentuate psychological distress for these regulated occupations? In order to better understand the role played by the regulated occupations in psychological distress, this thesis proposes a multidimensional theoretical model which postulates that the constraints and resources are generated by a set of social structures including the regulated occupation, the working conditions, family, social network outside of work and personal characteristics. This model stems from the micro and macro theories in sociology (Alexander et al., 1987; Ritzer, 1996), the agent-structure approach (Archer, 1995; Giddens, 1987) as well as the social stress theory (Pearlin, 1999). Three hypotheses are subject to analysis through the model. The first hypothesis assumes that regulated occupations, work conditions, family, social network outside the workplace, and individual characteristics contribute directly and jointly to explaining the level of psychological distress. The second hypothesis induced by the proposed model postulates that the workplace mediates the relationship between regulated occupations and psychological distress levels. The third and final research hypothesis postulates that the relationship between the workplace and psychological distress levels is moderated by individual characteristics, as well as by family and the social network outside the workplace.These hypotheses have been validated using longitudinal data from the National population health survey (NPHS) (cycles 1 to 7). The results of these analyses are presented in three articles submitted for publication, which are the chapters 5-7 of this thesis. Overall, the theoretical model gets an important empirical support and suggests that the regulated occupations directly influence the chances of living psychological distress over time as well as the level of psychological distress itself. The results also suggest that the regulated occupations are exposed to differentiated risks in terms of working conditions likely to generate psychological distress. The contribution of the workplace and regulated occupations is exercised independently of other dimensions of the model (family, social network outside of work, personal characteristics). The results also corroborate the importance in considering many dimensions of the life of an individual in the psychological distress and to put on the agenda the importance of developing new theoretical models, better suited to the realities characterizing today’s working environments in which knowledge workers work. This thesis concludes on the implications of these findings for research, and the benefits it brings to the labor market and for the future development of the professional system in Quebec and Canada.

The implications of the out of field phenomenon for school management

Du Plessis, Anna Elizabeth 30 November 2005 (has links)
The out of field phenomenon, that is, educators who teach outside their field of expertise, adds complexity to the education environment. This growing phenomenon in South African schools impacts colleagues, learners, parents, governing bodies and school management. Teaching characteristics that ensure success in classrooms are threatened by the out of field phenomenon. It puts extra strain on school management's responsibility to provide quality management and jeopardises effective teaching and quality learning. This problem was investigated by a literature study and an empirical investigation using a qualitative approach. Data was gathered through semi-structured interviews with selected participants who shared their experiences of the phenomenon. Findings indicated that the existence of the out of field phenomenon should be recognised in order to provide substantial educator support and sufficient staff development programmes. It is recommended that new evidence-informed knowledge about the out of field phenomenon can contribute to improve effective decision making and policy developing in this regard. / Education management / M.Ed.
