Thesis (MA (Afrikaans and Dutch))—University of Stellenbosch, 2009. / AFRIKAANSE OPSOMMING: In hierdie verhandeling word die briewe, wat Uys Krige tydens sy verblyf in Frankryk en Spanje tussen die jare 1931 en 1935 aan sy gesin en vriende geskryf het, in ’n geredigeerde vorm uitgegee, terwyl annotasies verskaf word waar dit nodig is om spesifieke persone te identifiseer en sekere gedeeltes, sover dit agterhaalbaar is, te verhelder. Op dié wyse sal Krige se briewe teen die agtergrond geplaas word van die Mediterreense wêreld wat hy in dié tydvak leer ken het. Terselfdertyd sal die groeiproses belig word wat hy as skrywer in hierdie belangrike fase van sy lewe deurgemaak het. Die hoofdoel van die studie is om, uitgaande van die beginsels van die hedendaagse edisiewetenskap, ’n leesbare teks te konstitueer wat egter steeds getrou aan Krige se oorspronklike briewe sal bly. Deur só ’n teks tot stand te bring, word terselfdertyd tot dusver grotendeels onbekende fasette van ’n prominente Afrikaanse skrywer bekend gestel. Die oorspronklike briewe is almal per hand geskryf en is aan die Nasionale Biblioteek in Kaapstad deur J.G.J. (Bokkie) Krige geskenk. Hy het egter eers die briewe oorgetik en in vier leergebonde bundels laat inbind wat tans in die besit is van Eulalia Krige, die dogter van die skrywer. ’n Fotokopie van die getikte briewe dien as die uitgangspunt van hierdie studie. Dit word getranskribeer, versorg en met die oorspronklike briewe vergelyk om te verseker dat die tekste korrek oorgetik is. Die briewe van Uys Krige aan sy familie, wat in hierdie studie opgeneem word, strek tussen die jare 1931, wanneer Krige, kort ná sy aankoms uit Londen, hom in die suide van Frankryk vestig, tot November 1935, wanneer hy uit Spanje, ná die publikasie van sy debuutbundel Kentering, na Suid-Afrika terugkeer. / ENGLISH SUMMARY: In this dissertation the letters of Uys Krige, which was written during his stay in France and Spain between the years 1931 and 1935, to his family and friends, are produced in an edited form, whilst annotations are provided where necessary to identify specific people and to, where possible, clarify some of the written parts. Thus Krige’s letters will be placed against the backdrop of the Mediterranean world which he came to know during this era. At the same time Krige’s growth as writer, which excelled during his European stay, will be highlighted. The aim of this dissertation is to construct a readable text which remains faithful to the original writings, based on the principles of the modern science of editions. By producing such a text, some previously unknown facets of a prominent Afrikaans writer are also brought to light. The original letters are all hand-written and were donated to the National Library in Cape Town by Krige’s brother, J.G.J. (Bokkie) Krige. However, the latter retyped these letters and bound it in four leather collections which are now in the possession of Eulalia Krige, the writer’s daughter. Photocopies of the letters serve as the starting point for this study. It is transcribed, edited and compared with the original letters to ensure the letters were retyped correctly. The letters of Uys Krige to his family which are collected in this dissertation stretch from 1931, when Krige, shortly after his arrival from London, finds himself in the south of France, until November 1935, shortly after the publication of his debut poetry collection Kentering and before he heads back to South Africa.

In this thesis we demonstrate the algorithmic usefulness of the so-called Mal'cev correspondence for computations with infinite polycyclic groups. This correspondence between Q-powered nilpotent groups and rational nilpotent Lie algebras was discovered by Anatoly Mal'cev in 1951. We show how the Mal'cev correspondence can be realized on a computer. We explore two possibilities for this purpose and compare them: the first one uses matrix embeddings and the second the Baker-Campbell-Hausdorff formula. Then, we describe a new collection algorithm for polycyclically presented groups, which we call Mal'cev collection. Algorithms for collection lie at the heart of most methods dealing with polycyclically presented groups. The current state of the art is "collection from the left" as recently studied by Gebhardt, Leedham-Green/Soicher and Vaughan-Lee. Mal'cev collection is in some cases dramatically faster than collection from the left, while using less memory. Further, we explore how the Mal'cev correspondence can be used to describe symbolically the collection process in polycyclically presented groups. In particular, we describe an algorithm that computes the collection functions for splittable polycyclic groups. This algorithm is based on work by du Sautoy. We apply it to the computation of pro-p-completions of polycyclic groups. Finally we describe a practical algorithm for testing polycyclicity of finitely generated rational matrix groups. Previously, not only did no such method exist but it was not clear whether this question was decidable at all. Most of the methods described in this thesis are implemented in the computer algebra system GAP and publicly available as part of the GAP packages Guarana and Polenta. Reports on the implementation including runtimes for some examples are given at the appropriate places.

Document distribution in a large corporation requires a set of routing procedures for each type of document. Documents may include memorandums, payroll reports, technical reports, external correspondence, and internal mail. Some of these documents may require managerial review and signature release authority to leave the organization. The document must be routed through the different levels of the organization according to the document procedures. The availability of the signers and reviewers becomes a delay factor in the routing of the document. This dissertation describes an approach to a solution to this problem using artificial intelligence and expert system concepts coupled with distributed computer networking to distribute the documents. A prototype system has been demonstrated. A document is originated as an "electronic file" on a user workstation (WS), called the Writer. The document is processed by an inference engine in the WS which also appends the list of Signers and Reviewers. The document is then sent to a Knowledge Base Server (KBS) which adds additional information regarding the distribution of the document. Each document contains headers for the communications network in the organization, distribution control header, and the document text body. The KBS stores the document according to the user profiles in the organizations. Activity of reviewing and signing the documents is originated at the user WS. The document is retrieved from the KBS, reviewed by the user, signed and returned to the KBS for intermediate storage. When the KBS has determined that the document has all the required signatures (Signwords), the document is sent to the final destination. The automated document distribution system summarized above has been demonstrated using a C language implementation on PC workstations and a UNIX-based KBS. The PCs are AT&T 6300 systems and the KBS is an AT&T 3B2/310 system. The communications network is a Sytek LocalNet 20 broadband local area network. Knowledge about document processing and distribution is distributed between local workstations' knowledge bases and the KBS. The second phase of the project involves implementing the system using AI and expert systems tools in the PCs and KBS.

This thesis draws upon modern consumption theory to provide an interpretive research framework for examining material culture and consumer behaviour in the Roman world. This approach is applied to data from twelve Pompeian households to identify patterns of consumption, materiality, and motivations for the acquisition of commodities. Analysis of the assemblage data is performed at multiple levels comprising weighted ranking of goods and the application of Correspondence Analysis, with investigation performed on both functional categories and artefact types. Setting the results against theories of consumption and rationality, consumer choice in the ancient world is examined. From this detailed examination of twelve Pompeian houses, ‘core’ and ‘fringe’ commodities and recurring suites of goods are identified. Non-luxury goods are given particular attention as they provide information concerning the consumption of everyday utility objects. This approach also allows the evaluation of statements about the state of occupation of houses in sites such as Pompeii. The results validate this form of analysis as an important tool for assessing the role of the consumer in economies of the ancient world, moving beyond concepts of conspicuous consumption and group values. This research provides a structured interpretive framework upon which varied archaeological data can be superimposed to interrogate the motivations behind commodity acquisition. This research also raises the potential for future consumption modelling using multivariate statistics. Through the application of consumer theory to Roman data, discussion of ancient economies is shifted away from a focus on production to one of demand, choice, and sites of consumption.

Bernardin de Saint-Pierre survived the French revolution and was subsequently lionised, becoming a member of the École Normale and the Institut. Maurice Souriau, and most recently Malcolm Cook have looked at his contributions during the French revolution. Both concluded that these were far more substantial than what some critics have hitherto claimed but neither of them conducted a systematic research in the newspapers of the time to see how his work was received. Nor did they consider the correspondence in this respect. This is what this thesis proposes to do. We originally intended to cover the years 1789 to 1799 but we discovered such a wealth of information concerning the first four years of the revolution that we decided to concentrate our research on that period. This ties in with Bernardin’s own publications since hardly anything new was published by him after 1792. This study has revealed that Bernardin had very strong political ideas which he expressed in 1789 with Vœux d’un solitaire and then again in 1792 with Suite des vœux d’un solitaire and in July of the same year he produced a poster entitled: L’Invitation à la Concorde pour la fête de la confédération au 14 juillet 1792. The first three chapters of this thesis analyse the reaction of the press and his correspondents to these publications. We then turn our attention to La Chaumière indienne, first published in 1791 and then again in 1792 where Bernardin included more notes concerning his views on the shape of the earth. If, by and large, the reception of this story was positive, his scientific views triggered enough commentary to justify a section of a chapter dedicated to them. As we progressed in our research, Bernardin’s importance at the time became increasingly evident and we realised that parallel to his own publications, ran an undercurrent of writings paying homage to the man and which we felt helped to build up a portrait of the period. We finish with his nomination as ‘Intendant du Jardin des Plantes’ in July 1792 which led him to write an appeal to create a zoo in the Jardin des Plantes. Throughout 1792 Bernardin’s name was rarely out of the newspapers. This study has shed new light on the persona of Bernardin and helped to underline his importance before, during and after the French revolution.

This study investigated effects of monitoring on correspondence between nonverbal responding and verbal descriptions of those contingencies, when verbal descriptions and contingencies were compatible and when incompatible. In the Nonverbal Component, the contingency for key pressing was either on a 0.8 s IRT or a 3.4 s IRT. In the Verbal Component, subjects made responses to a statement about the contingency for reinforcement in the Nonverbal Component. Shaping was used to establish targets of 0.8 s and 3.4 s in this component. Results indicated that across 7/8 opportunities subjects exhibited nonverbal and verbal behavior that was sensitive to their respective contingencies regardless of compatibility. This sensitivity to contingencies was not affected by the presence of a monitor.

Thomas Hardy described himself as "churchy". Yet his later novels and poetry gave him the reputation of being an agnostic, an atheist and a heathen. He denied that there was any particular philosophy behind his work claiming that it was the result of impressions not convictions. However, I wish to show that Hardy's fiction and poetry expose specific religious beliefs and doubts, that gave rise to his notoriously pessimistic art. By investigating the themes of sin, atonement and salvation, as reflected in the Mosaic Law and the New Testament against Hardy's mature novels, and examining Hardy's concept of God in his poetry, I aim to show that Hardy rejected the miraculous and the doctrine of redemption but retained a belief in the Biblical premiss that the earth is cursed and that humanity is governed by the Biblical Laws which dictate the consequences of sin. Hardy depicts a universe in which humankind is cursed from birth, resides on a cursed earth and is denied the possibility of salvation or redemption. Hardy's profoundly pessimistic world view is a result of his inability to accept the Christian doctrines that offer man a means to rise above the curse of original sin. The characters and plots he created in his fiction were born out of doubt and despair. Consequently, his imaginative universe is permeated with doom and damnation. / English Studies / M.A. (English)

Thesis advisor: Solomon Friedberg / We study a new lifting of automorphic representations using the theta representation ϴ on the 4-fold cover of the symplectic group, $\overline{\Sp}_{2r}(\A)$. This lifting produces the first examples of CAP representations on higher degree metaplectic covering groups. Central to our analysis is the identification of the maximal nilpotent orbit associated to ϴ. We conjecture a natural extension of Arthur's parameterization of the discrete spectrum to $\overline{\Sp}_{2r}(\A)$. Assuming this, we compute the effect of our lift on Arthur parameters and show that the parameter of a representation in the image of the lift is non-tempered. We conclude by relating the lifting to the dimension equation of Ginzburg to predict the first non-trivial lift of a generic cuspidal representation of $\overline{\Sp}_{2r}(\A)$. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.
