Magister Scientiae - MSc / This study examines the behaviour of the South African financial markets with regards to the Geometric Brownian motion process. It uses the daily, weekly, and monthly stock returns time series of some major securities trading in the South African financial market, more specifically the US dollar/Euro, JSE ALSI Total Returns Index, South African All Bond Index, Anglo American Corporation, Standard Bank, Sasol, US dollar Gold Price , Brent spot oil price, and South African white maize near future. The assumptions underlying the Geometric Brownian motion in finance, namely the stationarity, the normality and the independence of stock returns, are tested using both graphical (histograms and normal plots) and statistical test (Kolmogorov-Simirnov test, Box-Ljung statistic and Augmented Dickey-Fuller test) methods to check whether or not the Brownian motion as a model for South African financial markets holds. The Hurst exponent or independence index is also applied to support the results from the previous test. Theoretically, the independent or Geometric Brownian motion time series should be characterised by the Hurst exponent of ½. A value of a Hurst exponent different from that would indicate the presence of long memory or fractional Brownian motion in a time series. The study shows that at least one assumption is violated when the Geometric Brownian motion process is examined assumption by assumption. It also reveals the presence of both long memory and random walk or Geometric Brownian motion in the South African financial markets returns when the Hurst index analysis is used and finds that the Currency market is the most efficient of the South African financial markets. The study concludes that although some assumptions underlying the rocess are violated, the Brownian motion as a model in South African financial markets can not be rejected. It can be accepted in some instances if some parameters such as the Hurst exponent are added. / South Africa

The theoretical part describes the properties of fine-grained admixtures and the ways how these admixtures modify concrete properties. There are also described ways to assemble grain curves in the range 0-1000 m. The practical part describes the properties of all the concrete components used for the tests. From the admixtures and cement, the individual grain curves were compiled. Curves were assembled in the first stage manually by using MS Excel. Subsequently, a simple program was developed based on the knowledge of composing grain curves, which automatically compiles the grain curve according to the given limits. The maximum cement replacement was set at 25% by weight. The physical and mechanical properties of the graded curves thus established were first verified on mortar mixtures where the workability, bulk density and strength were verified at the age 7, 28 and 90 days. In addition, the porosity of cement cement with mercury porosimetry has been verified for selected recipes. The acquired knowledge was subsequently applied to the concrete in the laboratory. Here the maximum cement compensation was set at 30%. In particular, concrete consistency over time, air content in the concrete and compresive strength of concrete at the age 3, 7, 28 and 90 days were verified. Verification was also carried out in practice on the optimization of self-compacting concrete. Mechanical properties have been retained for optimized recipe but there were financial savings and CO2 emissions reductions compare with the original recipe.

Thesis (M. Com.(Economics)) -- University of Limpopo, 2017 / The relationship between unemployment, exchange rate and inflation has been a subject of debate for many years. Given the fact that South Africa is faced with a very low economic growth rate, inflation rate which is likely to go beyond the upper band of 6 percent and a high level of unemployment, policy makers are often faced with the trade-off between unemployment and inflation rate in the country. The purpose of this study is to determine the relationship between exchange rate, unemployment and inflation in South Africa. The study employed Johansen cointegration procedures and the vector error correction model (VECM) to capture the relationship between the variables. The Engle-Granger causality test was also employed to analyse causality amongst the variables. The results of Johansen cointegration test indicate that there is a long-run equilibrium relationship between the variables. The VECM also confirmed the existence of short-run equilibrium relationship between the variables. The nature of the relationship indicates that there is a significant negative relationship between unemployment and inflation in South Africa. This implies that policy makers are been faced with the trade-off between these two variables. The results further indicate that inflation is positively related to exchange rate, meaning a depreciation of the Rand (South African currency) in the foreign exchange market will feed to inflation in the home country. Furthermore, it is also indicated that unemployment is positively related to exchange rate. Meaning, a depreciation of the Rand in the foreign exchange market increases the level of unemployment in South Africa. All the results appeared to be significant. Policies aimed at lowering unemployment and inflation rate are recommended. It is also recommended that policy makers in South Africa take measures to improve the quality of education, skills training and steps to increase the labour intensity of production.

This thesis focuses on the legacy of Jonathan Edwards on the Particular Baptists by way of apprehending theories held by their congregations during the eighteenth and nineteenth centuries. In particular, special attention is directed to the Edwardsean legacy as manifested in the theology of Andrew Fuller. The thesis positions itself between Edwards and Fuller in the transatlantic, early modern period and attempts by the two theologians to express a coherent understanding of traditional dogma within the context of the Enlightenment. The scope of the research traces Fuller’s theological indebtedness by way of historical reconstruction, textual expositions, and theological and philosophical implications of the following works: Freedom of the Will, Religious Affections, Humble Attempt, and Justification by Faith Alone et al. It identifies unique Edwardsean ideas as the basis for investigating whether such concepts permeate Fuller’s intellectual and spiritual life. In that process, the study establishes whether Fuller read and interpreted Edwards correctly or otherwise. This dissertation, therefore, endeavors to determine the extent of Edwards’s impact upon Fuller over and above such other influential factors, which could also have been considered influential in his works. An attempt to determine the parameters of such factors is the basis for the ensuing discussion.

This project uses Michel Foucault’s underdeveloped notion of “tolerated illegality” as a departure point for two converging inquiries. The first analyzes, and then critiques, dominant legal logics and values. This part argues that traditional legal philosophers exhibit a “disagreement without difference,” generally concurring that legal certainty and predictability enhance agency. Subsequently, this section critiques “formal legal” logic by linking it to science envy (specifically the desire for certainty and predictability), and highlighting its agency- limiting effects (e.g. the violence of law en-force-ment). The second part examines multiple dimensions of tolerated illegality, exploring the permutations of this complex socio-legal phenomenon. Here the implications of tolerated illegality are mapped across different domains, ranging from the dispossession of Indigenous peoples of their lands, to the latent ideologies embedded in superhero shows. This section also examines the idea of liberal “tolerance,” as well as the themes of power, domination, politics, bureaucracy, and authority. Ultimately, this project demonstrates that it is illuminating to study legality and (tolerated) illegality in tandem because although analyses of “formal legality” provide helpful analytical texture, the polymorphous and entangled nature of tolerated illegality makes clear just how restricted and artificial strict analyses of legality can be. / Graduate

This thesis contributes to the literature on the history of the transition from colonial to post-colonial in the Pacific. It explores the contribution of an individual to this transition, Rev. Dr. Alan Richard Tippett, as a focus for illuminating the struggles in the transitions and the development of post-colonial theory for mission. Alan Richard Tippet sailed to Fiji as an ordained Methodist missionary in 1941. He was a product of a Methodist parsonage and heir to the evangelical and revival tendencies of the Cornish Methodism of his family. He began his missionary career steeped in the colonial visions of the mission enterprise fostered by the Board of Missions of his church. He was eager to study anthropology but was given no chance to do so before he left Australia. He pursued his study of anthropology and history in Fiji and began to question the paternalism of colonial theory. Early in his time in Fiji he made the decision to join with those who sought change and the death of colonial mission. In his work as a circuit minister, theological educator, writer and administrator he worked to this end. He developed his talent for writing and research, encouraging the Fijian church to take pride in its past achievements. He became alienated from the administrators of the Australasian Methodist Board of Missions and could find no place in the Australian church. In 1961 he left Fiji and began a course of study at the newly formed Institute of Church Growth in Eugene, Oregon. This led him into the orbit of Donald McGavran and the newly emerging church growth theory of Christian mission. Although his desire was to enhance the study of post-colonial mission in Australia he could not find a position to support him even after he gained a PhD in anthropology from the University of Oregon. After research in the Solomon Islands he returned to the USA to assist Donald McGavran in the formation of the now famous School of World Mission at Fuller Theological Seminary, Pasadena. While at Fuller he exercised considerable influence in the development of missiological theory and especially the application of anthropological studies in post-colonial mission. Although he contributed to both the ecumenical and evangelical debates on mission, he found himself caught up in the bitter debates of the 1960s and 1970s between them and, despite all efforts to maintain links, lost contact with the ecumenical wing. Retiring to Australia in 1977 he found that his world reputation was not recognised in his native land. He continued his work apace, although he was deeply saddened by the ignorance he found in Australia and by his continued rejection. He finally donated his library to St. Mark???s National Theological Centre. He died in 1988 in Canberra.

This dissertation utilizes theories of deviance in conjunction with literary methods of reading and analyzing to study a range of deviant or transgressive characters in American literature of the 1840s and 50s. I justify this methodology on the basis of the intersecting and related histories of Emersonian self-reliance and deviance in American thought. I contend that each of the texts of self-reliance discussed by the dissertation – The National Police Gazette (1845-present), Frederick Douglass’ Narrative of the Life of Frederick Douglass (1845) and My Bondage and My Freedom (1855), Margaret Fuller’s Woman in the Nineteenth Century (1845), Henry David Thoreau’s “Civil Disobedience” (1849) and Walden (1854), and Nathaniel Hawthorne’s The Scarlet Letter (1850) and The Blithedale Romance (1852) – actually sanctions deviance. Since deviance is endorsed by these texts in some shape or form, it is a critical component of American culture; consequently American culture is one that promotes deviance. My work on Douglass and Thoreau employs the sociological theories of Robert K. Merton (1949) to investigate the tensions between the culturally lauded goal of self-reliance and the legitimate means for securing this. I explore the importance of Transcendentalist self-reliance to the American Dream ethos and the ways in which it is valorized by each protagonist. The work on the National Police Gazette puts popular and elite forms of literary discourse into conversation with one another. My primary concern here is with explaining why and how specific self-reliant behaviours are deemed “deviant” in the literary context, but “criminal” by popular works. The chapters on female deviance elucidate the confines of women’s writing and writing about women as well as the acceptable female modes of conduct during the nineteenth century. They also focus on the ways female characters engaged in deviance from within these rigid frameworks. A functionalist interrogation of female deviance underscores the ways society is united against those women who are classed as unwomanly or unfeminine. My conclusion seeks to reinvigorate the conversation regarding the intersection between literature and the social sciences and suggests that literature in many ways often anticipates sociological theory. Ultimately, I conclude by broadening the category of the self-reliant individual to include, for instance, females and African-American slaves who were otherwise not imagined to possess such tendencies. Thus, this dissertation revises notions of Emerson’s concept of self-reliance by positioning it instead as a call to arms for all Americans to engage in deviant or socially transgressive behaviour.
