In this dissertation, the affinities between the Prologue of the Fourth Gospel and the Maronite Prayer of the Faithful especially the use of light metaphor are examined and new hypothetic proposals are suggested: the former has influenced the latter; both of them might have shared the same milieu or have been influenced by an existent Antiochene liturgical hymn. These proposals are discussed according to reflections on the Fourth Gospel, the Antiochene Syriac Maronite Church, the light metaphor, the work done on the Prologue from a socio-rhetorical perspective and the study conducted on the first English edition of the Maronite Prayer of the Faithful. / New Testament / M.Th.

The National Professional Diploma in Education is an in-service programme for classroom-based educators who have less than three years of professional training. The programme seeks to create a pathway to qualified teacher status in ways that will impact positively on classroom practice, prepare teacher-learners for the implementation of the new curriculum and provide a sufficiently rigorous foundation for further study. This evaluation adopted a fourth generation evaluation approach characterised by extensive engagement with programme stakeholders. Chapter 2 outlines an epistemological and philosophical framework of reference whilst Chapters 3 and 4 explore learning and teaching strategies and management and costing issues. The findings of these investigations lead to the recommendations made in Chapter 5. It is felt that the Unisa NPDE meets many of the goals of the programme, but further research is needed into the impact on classroom practice and into the management of the decentralised learner support. / Educational Studies / M.Ed.

The struggle between church and state continued during the thirteenth century. The crusades continued in the East with the advance of Islam. Crusades were also called for to put an end to heresies, in particular the Albigensian heresy. Unfortunately the established orders, such as the Cistercians, failed to combat heresy and to solve the problems of corruption in the Church. Scholastic theology developed with the establishment of the universities. These events influenced the thirteenth century. During the thirteenth century spiritual renewal began with Pope Innocent III. Councils like the Fourth Lateran Council defined church teaching and addressed corruption of the clergy. However, one of the most important sources of spiritual renewal came from the mendicant orders who had been given permission by Pope Innocent III to operate in the Church. These orders contributed immensely to education in the universities and through the Catholic laity culture advanced. / Die stryd tussen kerk en staat het voortgegaan gedurende die dertiende eeu. Die kruistogte het voortgeduur in die Ooste met die aanruk van Islam. Kruistogte was ook aangeroep om sodoende ‘n einde te maak aan kettery, veral Albiganiese kettery. Ongelukkig die ontwikkelde heerskappye, soos die Cisteriaanse orde, het nie daarin geslaag om probleme soos kettery en korrupsie in die kerk op te los. Skolastiese teologie het ontwikkel met die vestiging van die universiteite. Hierdie gebeure het ‘n kardinale impak gehad op die dertiende eeu. Gedurende die periode, het geestelik hernuwing begin met Pous Innocent III. Owerhede soos die Vierde Laterniese Owerheid het godsdiens onderrig, gedefinieer en korrupsie aangespreek. Tog, was een van die belangrikste bronne van geestelike hernuwing, die Bedelmonnik Orde, wat toestemming van Pous Innocent III gekry het om in die kerk te handel. Hierdie orde het bygedra tot onderig in universiteite en deur Katoliek leke het kultuur voortgespruit. / Christian Spirituality, Church History and Missiology / M. Th. (Church History)

John 21 tells of the “miraculous draught of fishes.” The disciples fish all night and catch nothing. In the morning, they fail to recognize Jesus on the shore, instructing them to cast their net again. After an amazing catch and subsequent breakfast, Jesus thrice questions Peter’s love and commissions him to “feed my sheep.” Using Narrative Criticism, this study examines this recognition scene, specifically in light of recognition scenes in Genesis. Previous work used primarily Greco-Roman texts to analyze Johannine recognition. This study adds the Hebraic perspective, asking, “How would a reader, well acquainted with Genesis, understand recognition in John 21?” This study labels characters who withhold recognition from others as “manipulators,” and argues that biblical recognition can be understood within a context of “manipulation.” It proposes a taxonomy of manipulation with six narrative kernels. This yields four patterns gleaned from Genesis: 1) Manipulation narratives are focused around chosen leaders—manipulators—undergoing a character development process; 2) These manipulators disempower others while empowering themselves for gain; 3) Genesis manipulation stories often contain evocative déjà vu motifs: repetitive words and themes connecting the units, reinforcing the story, and sometimes haunting manipulators; 4) Manipulators are often “counter-manipulated” in a reciprocal manner ironically similar to their own previous behavior. This may correct and transform the manipulator. The taxonomy and patterns are applied to John 21:1-19 as a lens for a new reading. The study also examines Greek diminutives in John 21, which enhances the reading. This reading characterizes Peter’s earlier behavior in John 18 as manipulative, when he withheld his identity three times. When the disciples go aimlessly fishing in John 21, Jesus actively withholds his identity in ironic counter-manipulation, mirroring Peter’s earlier denials. The disciples’ lack of recognition underscores their dullness, especially Peter’s. Jesus’ three questions to Peter continue the ironic counter-manipulation, paralleling Peter’s earlier three denials. Finally, Jesus predicts Peter will glorify God in his death, indicating his future turn toward ideal discipleship. / New Testament / D. Th. (New Testament)

The diploma work deals with the analysis of the logistic chain of the company Friall s.r.o., which is a producer of frozen potato specialities. Based on this analysis I wanted to discover weak points in functionality of the logistic chain and find suitable precautionary measures as well as solutions leading to an improvement of the current situation. The diploma work is focused on the raw material entry and self-production of the products.

Le « théâtre sur le théâtre », procédé par lequel le théâtre se prend explicitement pour objet, connaît en France, entre 1680 et 1762, une vogue inégalée : à l’exception de l’Opéra, il concerne plus du quart du répertoire comique créé sur les scènes publiques de Paris. Cette étude s’appuie sur plus de quatre cents pièces et se concentre sur une sélection de cent vingt-sept d’entre elles, jouées à la Comédie-Française : principalement des prologues dramatiques et des comédies en un acte, des « comédies de comédiens », des « comédies de spectateurs », des pièces allégoriques et des pièces d’actualité. Le théâtre autoréflexif, où s’exerce en action une conscience critique aux yeux du public, permet de retracer l’histoire d’un art, tel qu’il se donne à voir. Sur un plan pratique, il se fait le miroir des realia de la vie théâtrale en dévoilant les dynamismes de la conception d’un ! spectacle et de sa performance. Il aborde des enjeux qui touchent encore à la dramaturgie [conditions de représentation], à la poétique [apparition des genres nouveaux], à l’esthétique [fabrique de l’illusion] et à la vie institutionnelle des théâtres [querelles dramatiques]. Il interroge l’ancrage et la fonction du théâtre dans le monde en offrant un reflet prismatique de la société. L’étude présentée trace les contours de ce phénomène et de ses évolutions. Elle propose de repérer, en contexte, les enjeux idéologiques de ce répertoire, les effets qu’il provoque sur le spectateur, ainsi que les stratégies qu’il met en œuvre dans le fonctionnement du champ littéraire. / « Metatheatrical theatre » – theatre looking at itself and taking itself as its own object—flourished between 1680 and 1762, reaching unequalled proportions. More than a quarter of all the comic plays created in the Parisian public theatres of the time, apart from the Opera, consisted in metatheatre. Dealing with more than four hundred plays, this study focuses on a selection of one hundred and twenty-seven plays staged at the Comédie-Française—including mainly dramatic prologues, one-act comedies, comedians’ comedies, spectators’ comedies, allegorical plays and topical plays. Self-reflexive theatre allows us to retrace the history of an art which performed its critical consciousness before the spectator’s eyes. From a practical point of view, this repertoire mirrored the realia of theatrical life, by exhibiting the dynamics at work in the staging and acting of a play. From an aesthetic point of view, it raised central issues! related to the art of performance [the staging conditions], the institutional life of theatres [dramatic quarrels], poetics [the emergence of new genres] and aesthetics [the construction of theatrical illusion]. On an ideological level, they offered a prismatic reflection of society, thus developing a concrete questioning on the social inscription and function of theatre. The present study aims at mapping the modalities and evolution of this phenomenon. It seeks to bring out the ideological stakes of this repertoire, the effects it produced on the audience, as well as the strategies of its positioning in the literary field.

In most breeding programmes breeders use phenotypic data obtained in breeding trials to rank the performance of the parents or progeny on pre-selected performance criteria. Through this ranking the best candidates are identified and selected for breeding or production purposes. Best Linear Unbiased Prediction (BLUP), is an efficient selection method to use, combining information into a single index. Unbalanced or messy data is frequently found in tree breeding trial data. Trial individuals are related and a degree of correlation is expected between individuals over sites, which can lead to collinearity in the data which may lead to instability in certain selection models. A high degree of collinearity may cause problems and adversely affect the prediction of the breeding values in a BLUP selection index. Simulation studies have highlighted that instability is a concern and needs to be investigated in experimental data. The occurrence of instability, relating to collinearity, in BLUP of tree breeding data and possible methods to deal with it were investigated in this study. Case study data from 39 forestry breeding trials (three generations) of Eucalyptus grandis and 20 trials of Pinus patula (two generations) were used. A series of BLUP predictions (rankings) using three selection traits and 10 economic weighting sets were made. Backward and forward prediction models with three different matrix inversion techniques (singular value decomposition, Gaussian elimination - partial and full pivoting) and an adapted ridge regression technique were used in calculating BLUP indices. A Delphi and Clipper version of the same BLUP programme which run with different computational numerical precision were used and compared. Predicted breeding values (forward prediction) were determined in the F1 and F2 E. grandis trials and F1 P. patula trials and realised breeding performance (backward prediction) was determined in the F2 and F3 E. grandis trials and F2 P. patula trials. The accuracy (correlation between the predicted breeding values and realised breeding performance) was estimated in order to assess the efficiency of the predictions and evaluate the different matrix inversion methods. The magnitude of the accuracy (correlations) was found to mostly be of acceptable magnitude when compared to the heritability of the compound weighted trait in the F1F2 E. grandis scenarios. Realised genetic gains were also calculated for each method used. Instability was observed in both E. grandis and P. patula breeding data in the study, and this may cause a significant loss in realised genetic gains. Instability can be identified by examining the matrix calculated from the product of the phenotypic covariance matrix with its inverse, for deviations from the expected identity pattern. Results of this study indicate that it may not always be optimal to use a higher numerical precision programme when there is collinearity in the data and instability in the matrix calculations. In some cases, where there is a large amount of collinearity, the use of a higher precision programme for BLUP calculations can significantly increase or decrease the accuracy of the rankings. The different matrix inversion techniques particularly SVD and adapted ridge regression did not perform much better than the full pivoting technique. The study found that it is beneficial to use the full pivoting Gaussian elimination matrix inversion technique in preference to the partial pivoting Gaussian elimination matrix inversion technique for both high and lower numerical precision programmes. / Thesis (PhD)--University of Pretoria, 2013. / gm2014 / Genetics / unrestricted

Text in English / In recent years, there have been tremendous advances in information technology, robotics, communication technology, nanotechnology, and artificial intelligence, resulting in the merging of physical, digital, and biological worlds that have come to be known as the "fourth industrial revolution”. In this context, the present study engages such technology in the green economy and to tackle the techno-economic environmental impact assessments challenges associated with floating solar system applications in the agricultural sector of South Africa. In response, this exploratory study aimed to examine the development of a Geographical Information System (GIS)-based support platform for Environmental Impact Assessment (EIA) and due-diligence analyses for future planned agricultural floating solar systems, especially with the goal to address the vast differences between the environmental impacts for land-based and water-based photovoltaic energy systems. A research gap was identified in the planning processes for implementing floating solar systems in South Africa’s agricultural sector. This inspired the development of a novel GIS-based modelling tool to assist with floating solar system type energy infrastructure planning in the renewable energy discourse. In this context, there are significant challenges and future research avenues for technical and environmental performance modelling in the new sustainable energy transformation. The present dissertation and geographical research ventured into the conceptualisation, designing and development of a software GIS-based decision support tool to assist environmental impact practitioners, project owners and landscape architects to perform environmental scoping and environmental due-diligence analysis for planned floating solar systems in the local agricultural sector. In terms of the aims and objectives of the research, this project aims at the design and development of a dedicated GIS toolset to determine the environmental feasibility around the use of floating solar systems in agricultural applications in South Africa. In this context, the research objectives of this study included the use of computational modelling and simulation techniques to theoretically determine the energy yield predictions and computing environmental impacts/offsets for future planned agricultural floating solar systems in South Africa. The toolset succeeded in determining these aspects in applications where floating solar systems would substitute Eskom grid power. The study succeeded in developing a digital GIS-based computer simulation model for floating solar systems capable of (a) predicting the anticipated energy yield, (b) calculating the environmental offsets achieved by substituting coal-fired generation by floating solar panels, (c) determining the environmental impact and land-use preservation benefits of any floating solar system, and (d) relating these metrics to water-energy-land-food (WELF) nexus parameters suitable for user project viability analysis and decision support. The research project has demonstrated how the proposed GIS toolset supports the body of geographical knowledge in the fields of Energy and Environmental Geography. The new toolset, called EIAcloudGIS, was developed to assist in solving challenges around energy and environmental sustainability analysis when planning new floating solar installations on farms in South Africa. Experiments conducted during the research showed how the geographical study in general, and the toolset in particular, succeeded in solving a real-world problem. Through the formulation and development of GIS-based computer simulation models embedded into GIS layers, this new tool practically supports the National Environmental Management Act (NEMA Act No. 107 of 1998), and in particular, associated EIA processes. The tool also simplifies and semi-automates certain aspects of environmental impact analysis processes for newly envisioned and planned floating solar installations in South Africa. / Geography / M.Sc.
