Babel, babble, and Babylon : reading Genesis 11:1-9 as myth

Oosthuizen, Neil T. 25 August 2009 (has links)
The story of the Tower of Babel (Gen 11: 1-9) has been interpreted in various ways down through the centuries. However, most commentators have ignored the genre of the text, and have not sought to interpret it within its mythological framework - therefore most interpretations are nothing short of babble. A working text is ascertained, and the complexity of the text investigated. The text is then identified as 'myth': within its mythological framework the tower is seen as a temple linking heaven and earth, ensuring the continuation of the royal dynasty (i e 'making a name'). When used by the Yahwist Levites during the Babylonian Exile, our story was inserted in the great Pre-History as polemic against the Babylonian concept of creation, temple, and dynasty; and served as both a warning and an encouragement to the Exiles. The post-exilic Priestly Writer re-interpreted our story as a warning to the returning exiles that their society, and their temple, should be reconstructed as YHWH determines. Interpreting the story as myth enables it, finally, to speak clearly into our context today, especially that of South Africa. / Biblical and Ancient Studies / D. Th. (Old Testament)

Palimpsestic writing and crossing textual boundaries in selected novels by A.S. Byatt / Therina van der Westhuizen

Van der Westhuizen, Therina January 2014 (has links)
This dissertation examines three novels by the author and critic A.S. Byatt, namely Possession (1990), Babel Tower (1996) and The Biographer’s Tale (2000), using a hermeneutic method of analysis. The investigation pays specific attention to the structure of the novels and how this compares to the structure of the ancient palimpsest. Theoretical information on the palimpsest as model is based on relevant writings by Thomas Carlyle (1830, 1833), Thomas De Quincey (1845) through to Josephine McDonagh (1987), Gérard Genette (1997) and Sarah Dillon (2007). The ensuing argument is that Byatt’s use of postmodernist pseudo-intertextuality and intertextuality cause her novels to have a palimpsestic structure of various layers, with the effect that textual boundaries are transgressed. Ultimately Byatt’s writing strategies result in ontological uncertainty for the reader. / MA (English), North-West University, Potchefstroom Campus, 2014.

Stavba Babylonské věže (anylýza hebrejského textu Geneze 11) / The Building of the Tower of Babel (analysis of hebrew text genesis 11)

Říhová, Kristýna January 2012 (has links)
ANOTATION The work deals with translation and interpretation of the original Hebrew text of Genesis 11, making the use of synchronous exegetical method. The method focuses mostly on careful observation of multi-layered meanings of Hebrew terms, direct speeches, macrosyntactical markers, parallelisms and sentence constituents. To reach deeper dimension of the text, the work also takes into account the original non-vocalized text, graphical form of the text, consonances and metathesis. One of the most significant features of this work is the attention paid to the timeless nature of Hebrew verbs, which allows to read the narrative about human desire, pride, non-hearing, illusions, inner decay and the way back to God not as a story from the past, but as a lively anthropological message.

Projeto baseado em desempenho de torres metálicas sujeitas à ação do vento / Performance-based design of steel towers subject to wind action

Tessari, Rodolfo Krul 25 February 2016 (has links)
A Engenharia de Ventos Baseada em Desempenho (Performance-based Wind Engineering - PBWE) é uma filosofia de projeto que preconiza identificar e quantificar as incertezas envolvidas no projeto estrutural a fim de assegurar níveis previsíveis de desempenho às edificações, não mais gerenciando o risco através da clássica abordagem determinística. Contudo, devido à recente proposição da metodologia, ainda há poucos estudos relacionados à PBWE, cada qual apresentando diferentes limitações. Assim, o presente trabalho propõe uma adaptação da metodologia da Engenharia de Ventos Baseada em Desempenho à análise probabilística do comportamento de torres metálicas, avaliando diferentes modelos de cálculo para estimativa das forças do vento neste tipo de estrutura. Para tanto, investigou-se as incertezas envolvidas na caracterização do campo de ventos e da resistência estrutural e foram analisados quatro métodos distintos para a estimativa das forças de vento em torres metálicas: dois procedimentos de cálculo correspondentes à norma brasileira de ventos ABNT NBR 6123:1988 (ABNT, 1988), a metodologia de Davenport (1993) e a de Holmes (1994). Um estudo de caso envolvendo a estimativa da confiabilidade de uma torre de telecomunicação também foi conduzido. Constatou-se que ambos os procedimentos de cálculo admitidos conduzem a níveis de segurança de mesma ordem de grandeza e que a elaboração de projetos de torres considerando a direção de incidência do vento como sendo a mais desfavorável à estrutura é demasiadamente conservadora. Como contribuição, verifica-se que o projeto ótimo de torres pode ser alcançado com base no nível de segurança desejado para diferentes velocidades máxima de vento associadas a intervalos de recorrência específicos. / Performance-based Wind Engineering (PBWE) is a design philosophy that aims to identify and quantify the uncertainties involved in the structural design in order to ensure predictable performance levels to buildings, no longer managing risk through the classical deterministic approach. However, due to the recent proposal of the methodology, there are few studies related to PBWE, each presenting different limitations. Thus, this paper proposes an adaptation of the Performance-based Wind Engineering methodology to the probabilistic analysis of the behavior of steel towers, evaluating different calculation models for estimating wind forces on this type of structure. To this end, uncertainties involved in the characterization of the wind field and structural strength were investigated and four different methods for the estimation of wind forces on steel towers were analyzed: two procedures relative to the Brazilian winds standard ABNT NBR 6123:1988 (ABNT, 1988), and the methodologies of Davenport (1993) and Holmes (1994). A case study concerning the reliability estimation of a telecommunication tower was also conducted. It was found that both assumed calculation procedures lead to security levels of the same order of magnitude and that the design of towers considering that the wind always blows from the worst direction is too conservative. As a contribution, it is found that the optimum design of towers can be achieved based on the desired security level for different maximum wind speeds associated to specific recurrence intervals.

L'église Saint-Michel, la fabrique d'un monument : étude historique, artistique et archéologique de l'église Saint-Michel de Bordeaux / The church of St Michael, the fabric of a monument : Historic, artistic and archaeological study about the church of St Michael of Bordeaux

Drapeau, Samuel 24 October 2016 (has links)
L’église Saint-Michel de Bordeaux est construite à la fin du Moyen Âge au centre d’une paroisse urbaine très dynamique. L’activité portuaire et commerciale fait vivre de nombreux artisans et enrichit les puissants marchands du quartier de la Rousselle. Ils sont investis dans le gouvernement de la commune et financent copieusement le chantier de leur église paroissiale. Leurs pratiques pieuses et leur activité à la tête de l’administration de la fabrique et des confréries sont représentatives de la religion civique à la fin du Moyen Âge. L’église accueille depuis la fin du XVe siècle un collège de prêtres-bénéficiers, au service des nombreuses fondations pieuses et des confréries installées dans les chapelles latérales. Elles sont construites durant le second chantier gothique, qui met en œuvre à partir du second quart du XVe siècle une vaste église flamboyante de plan basilical. Celle-ci succède à une première église gothique menée à son terme durant le XIVe siècle selon un parti-pris architectural de type « halle ». Le chantier de la cathédrale, qui introduit à Bordeaux les formes du gothique rayonnant du Nord de la France, est une source d’inspiration à Saint-Michel, dans le domaine de la modénature et de la sculpture monumentale. Le chantier flamboyant voit l’arrivée de maîtres-maçons dont l’œuvre a pu être identifiée. Elle se réfère aux chantiers normands, parisiens ou financés par le roi de France. Les Lebas de Saintes apportent leur culture artistique et leur technique à l’accomplissement du transept, à la conception de la nef et du clocher isolé. La faible influence de l’œuvre de Saint-Michel sur la création artistique locale est compensée par le rayonnement de son clocher-tour, un des plus hauts clochers du royaume. Son chantier exceptionnel est très bien renseigné par 11 années de comptes de la fabrique. Ils illustrent les conditions de travail et l’équipement nécessaire à la construction à grande hauteur. Un des autres chefs-d’œuvre de l’église, le portail nord, est probablement réalisé vers 1520 par Imbert Boachon, maître-maçon, imagier, menuisier, selon la nature des travaux et selon les villes ou il travaille. Aujourd’hui, la silhouette de l’église et du clocher, tous deux isolés au milieu de plusieurs places, ne reflète plus totalement la morphologie de l’œuvre médiévale. Des faiblesses structurelles obligent les hommes du XIXe siècle à reconstruire le chevet. Le clocher est rénové par Paul Abadie et l’église reçoit une esthétique gothique influencée par l’archéologie monumentale et les doctrines de la restauration patrimoniale de l’époque. / The church of St Michael of Bordeaux has been built in the late Middle Ages, in a very dynamic urban parish. The fluvial and commercial activities of the port generate work for craftsmen and enrich the powerful merchants from the borough of La Rousselle. These merchants are invested in the communal government and finance the building of their parish church. Their pious practices and their activity at the head of the parish fabric and friaries are good examples of the late medieval civic religion. From the end of the fifteenth century, the church receives a college of priest provided by religious benefits. They are in the service of many pious foundations and friaries which are established in the lateral chapels. These chapels are built during the second gothic construction, which makes a big Flamboyant style church with the plan of a basilica. This building follows a first gothic church, conducted at its term during the fourteenth century in accordance to a “halle” architectural volume. The construction of the cathedral of Bordeaux, which introduces the gothic style from the north of France, is an inspiration for St Michael, in the domain of modenature and monumental sculpture. The Flamboyant construction induces the arrival of some master mason, whose work can be identified. That work is influenced by Norman, Parisian and French king’s financed buildings. The Lebas from Saintes give their artistic culture and their technique to the accomplishment of the transept, to the conception of the nave and the isolated bell tower. The low influence of the work of St Michael of Bordeaux on the local artistic creation is balanced with the bell tower, one of the tallest in the French kingdom. Its constructions are well informed thanks to an eleven years’ register for the fabric accounting. It illustrates the work conditions and the necessary equipment for high tall building. One of the masterworks of the church, the north portal, is probably made around 1520 by Imbert Boachon, master mason, sculptor or joiner according to the kind of the work or the town where he works. Nowadays, the silhouette of the church and the bell tower are isolated in the middle of many places and are not totally representative of the medieval made morphology. Some structural frailties oblige the nineteenth century men to rebuild the chevet. The bell tower is renovated by Paul Abadie and the church receives a gothic aesthetic which is influenced by monumental archaeology and the patrimonial restorations doctrines of that period.

The effect of target fascination on control and situation awareness in a multiple remote tower center : A human factors study

Sjölin, Victor January 2015 (has links)
The Multiple Remote Tower Center concept (mRTC) is a cutting edge project which allows one air traffic control officer (ATCO) to be in charge of multiple remotely situated airports simultaneously. When implemented, it will revolutionise how air traffic is managed at smaller airports and allow for increased efficiency and decreased operational costs. Consequently, at the time of writing a lot of effort is going into evaluating this new way of air traffic management from a safety perspective. Air traffic management has been defined as an issue maintaining situational awareness and exercising control. This thesis aims to investigate how the phenomenon target fascination affects the ATCOs ability to exercise control over its controlled airspace and maintain its situation awareness. It does so by creating a baseline scenario of work in a mRTC, and then comparing the ATCOs performance in the baseline scenario with its performance in the same corresponding scenario, but with elements of target fascination introduced. The differences in the scenarios are analysed using the Contextual Control Model, the Extended Control Model and a holistic framework for studying situation awareness. The analysis shows that target fascination does affect the ATCOs ability to maintain control, but not radically so, and only for a short period of time. The target fascination forces the ATCO to rely on information in the immediate environment to a higher degree than during regular work, as opposed to making decisions based on a holistic understanding of the situation and high level goals. However, once the understanding of the situation have been re-established, the level of control quickly returns to normal levels. Situation awareness is thus a key concept in maintaining control. The situation awareness analysis show that target fascination affects situation awareness by causing the ATCOs understanding of the situation to become outdated without the ATCOs knowledge. Because of this, there may be developments in the situation that the ATCO is not aware of, which hinders it from acting as it normally would. In some cases an intervention from an external actor or element may be necessary to break the fascination and re-establish the ATCOs understanding for the situation. As soon as the fascination is broken, the ATCO quickly takes steps to re-establish its situation awareness and return to normal operations.
