- Description: This thesis critically analysed the apportionment of dual-purpose expenditure. In doing so, two categories of dual-expenditure were examined: expenditure that has been incurred for both trade and non-trade purposes, and expenditure that has been incurred to produce both taxable and exempt income. In conducting this analysis, this thesis set out to answer three questions: has the apportionment of dual-purpose expenditure been officially sanctioned in South Africa, when does the need for apportionment arise, and on what basis should a taxpayer apportion expenditure that has been incurred for a dual purpose? A doctrinal methodology was applied to the documentary data which consisted of relevant tax legislation; South African, Australian and English case law; and commentary of experts in the field of tax law. From the analysis performed, it was revealed that the apportionment of dual-purpose expenditure has been officially sanctioned in South Africa. In addition, it was concluded that the applicable legal principles for determining the need for apportionment and for performing the apportionment calculation are clear and well-established. The difficulty which taxpayers, the courts and the South African Revenue Service face, however, is applying these principles in practice. This research therefore concluded that there is a need for further guidance in this complex area of tax law. In addition, this research proposed some recommendations which could provide more certainty and clarity.

- Description: The effectiveness of monetary policy in achieving its macroeconomic objectives such as price stability and economic growth depend on the monetary policy tools that are implemented by the Central Bank. Monetary aggregates are one of the tools that have been used as indicators of economic activity and as intermediate targets to achieve these economic objectives. Until recently, monetary aggregates have been questioned and criticised on their usefulness in monetary policy. This has been attributed to the economic, financial and technological developments that have distorted the relationship between monetary aggregates and major macroeconomic variables. This study investigates the relevance of monetary aggregation by comparing the traditional simple sum and Divisia index monetary aggregates which was constructed for the first time for South Africa using the Tornquist-Theil method. The Polynomial Distributed Lag model is employed to compare the performance of these monetary aggregates using their relationship with inflation and manufacturing index. Furthermore, the aggregates are compared in terms of their controllability and information content. Overall, the study found a very strong relationship between inflation and all the monetary aggregates. However, more specifically the results suggested that the Divisia indices are superior to the simple sum in terms of predicting inflation. The evidence further suggests that the Divisia aggregates provide higher information about inflation than the simple sum aggregates. Regarding the controllability of the monetary aggregates, the findings suggest that the monetary authorities can hardly control the monetary aggregates using monetary base. Finally, the relationship between manufacturing index and all the monetary aggregates was very weak.

It explores the history, structure, performance and key issues related to the development of this market within the broader context of domestic, regional and global bond market development. BESA's experience provides valuable lessons for other emerging market economies also seeking to build bond markets. The sophistication of the local bond market is not enough to make it appealing to foreign borrowers. Market development demands an enabling market infrastructure and a background of macroeconomic stability, diversified market participants, deregulation of capital flows and an appropriate regulatory and supervisory environment.

- Description: This thesis describes the development of an ionospheric map for the South African region using the current available resources. The International Reference Ionosphere (IRI) model, the South African Bottomside Ionospheric Model (SABIM), and measurements from ionosondes in the South African Ionosonde Network, were incorporated into the map. An accurate ionospheric map depicting the foF2 and hmF2 parameters as well as electron density profiles at any location within South Africa is a useful tool for, amongst others, High Frequency (HF) communicators and space weather centers. A major product of the work is software, written in MATLAB, which produces spatial and temporal representations of the South African ionosphere. The map was validated and demonstrated for practical application, since a significant aim of the project was to make the map as applicable as possible. It is hoped that the map will find immense application in HF radio communication industries, research industries, aviation industries, and other industries that make use of Earth-Space systems. A potential user of the map is GrinTek Ewation (GEW) who is currently evaluating it for their purposes

- Description: Malingering has become an increasing concern in neuropsychological assessment in recent years, and a wide range of tests have been designed and examined for the purpose of detecting malingering. Cut-off scores have been recommended for these tests in order to provide indications of malingering performances. However, the derived scores have been in respect of westernised populations of people with relatively high levels of education who speak English as their first language. Accordingly, the current study aimed to attain normative data and cut-off scores for four commonly employed neuropsychological tools, administered in English, on a population of black, South African, Xhosa-speaking people (N = 33), who attended a former DET-type school in the Eastern Cape, with a Grade 11-12 level of education, in the age range of 18 - 40 years. The targeted measures included the TOMM, the Rey-15 Item Memory Test, the Digit Span subtest of the WAIS-III, and the Trail Making Test. The obtained scores were poorer than the previously published cut-offs for at least one component of each of the tests investigated, except the TOMM. The fmdings of this study highlight the important role that the factors of culture, quality of education, and language play in neuropsychological test performance.

- Description: The international dilemma of child soldiers is a humanitarian concern throughout the world. The Coalition to Stop the Use of Child Soldiers (CSUCS) began in 1998 and is currently the leading collaborative movement to address the issue. However, because of its emphasis on a universal 'Straight 18' approach and support of the Optional Protocol of the Convention on the Rights of a Child (CRC), the CSUCS ignores contextual realities that affect the implementation ofthe international legislation and the development of norms concerning child soldiers. This research project will examine the current international nongovernmental organization (INGO) response to child soldiers- focusing on the CSCUS - and formulate suggestions for potential avenues to further INGO involvement with policies and projects. The argument is based on a neoliberal institutionalist platform that argues in favour ofiNGOs' ability to successfully influence actions taken by state actors to address human right issues. Highlighting the successful INGO influence on states during the International Campaign to Ban Landmines, I will present this example as a potential model for the Coalition to Stop the Use of Child Soldiers, and explore the feasibility of this model whilst making suggestions for more effective involvement of INGOs with regard to the issue of child soldiers.

A new empirical model for the peak ionospheric electron density using neural networks

- Description: This thesis describes the search for a temporal model for predicting the peak ionospheric electron density-(foF2). Existing models, such as the International Reference Ionosphere (IRI) and 8KYCOM, were used to predict the 12 noon foF2 value over Grahamstown (26°E, 33°8). An attempt was then made to find a model that would improve upon these results. The traditional method of linear regression was used as a first step towards a new model. It was found that this would involve a multi variable regression that is reliant on guessing the optimum variables to be used in the final equation. An extremely complicated modelling equation involving many terms would result. Neural networks (NNs) are introduced as a new technique for predicting foF2. They are also applied, for the first time, to the problem of determining the best predictors of foF2. This quantity depends upon day number, level of solar activity and level of magnetic activity. The optimum averaging lengths of the solar activity index and the magnetic activity index were determined by appling NNs, using the criterion that the best indices are those that give the lowest rms error between the measured and predicted foF2. The optimum index for solar activity was found to be a 2-month running mean value of the daily sunspot number and for magnetic activity a 2-day averaged A index was found to be optimum. In addition, it was found that the response of foF2 to magnetic activity changes is highly non-linear and seasonally dependent. Using these indices as inputs, the NN trained successfully to predict foF2 with an rms error of 0.946 MHz on the daily testing values. Comparison with the IRI showed an improvement of 40% on the rms error. It is also shown that the NN will predict the noon value of foF2 to the same level of accuracy for unseen data of the same type.

Certain aspects of eroticism in twentieth century western painting

- Description: In this essay eroticism will be examined as it appears in some twentieth century representational styles. The decision to concentrate on the representational styles is based on the fact that eroticism is by nature incompatible with the non-representational or non-objective movements in art. This incompatibility is rooted in the knowledge that eroticism is intrinsically and fundamentally a human experience and could therefore find expression only in an art which is concerned with human experience, i.e. experiences which refer to man, his nature and his relation to Nature. It would be oversimplified and grossly inaccurate to equate the nonrepresentational with the abstract, abstraction being an element present in all art to a greater or lesser degree. However, when abstraction has reached the stage where it can define its aims, as, in the words of Kandinsky, "widening the separation between the domain of art and the domain of Nature", (Lake & Maillard: A Dictionary of Modern Painting, p. 1) then it may also approach the realm of the non-representational. When Michel Seupher states, "I call abstract art all art that does not recall or evoke reality", (Lake & Maillard: A Dictionary of Modern Painting, p. 136) abstract and nonrepresentational art becomes fused into an inseparable unity. Erotic expression will then be incompatible with this degree of abstraction. Intro., p. 1.
