- Description: The purpose of this study was to explore academic learning experiences of students who have dropped out of postgraduate studies in a Higher Education Institution in Eastern Cape. The study employed phenomenological approach using unstructured in-depth interviews to collect data from participants who have dropped out of Masters Programme in HEI in Eastern Cape. Four participants participated in this study. A lot of themes emerged from what the participants reported and similar experiences were noted as well as different experiences. Central to what this study ascertained is the relationship between the supervisor and supervisee. From the findings of the study it can be ascertained that for any postgraduate student to succeed in his/her studies he / she needs a positive relationship with the supervisor who will play a role of guide, mentor, supporter and a friend. However, the academic preparedness of the students in terms of academic reading and writing, computer literacy and determination to be an independent researcher is also key. Whilst this study provides insight to what the students have experienced academically its findings cannot be generalised because the experiences are those of individuals.

- Description: The study was looking at achieving more cost-effective implementation of the Eastern Cape Thicket Rehabilitation Project. Project management has been identified as a key for a proper implementation of any kind of work. For project management to be effective, individual learning and development of project managers is of paramount importance. An improved communication process is vital, that clearly specifies objectives if any success will be achieved. A proper and structural way of addressing change is a need, so that no unnecessary delays are experienced. A need is there for processes to be streamlined to avoid duplications as they are unnecessary costs. Employees need to be given an opportunity to have their ideas looked at, a way of testing if they really have been empowered. The important thing is that their views must speak to the standards of the project. Reductions in costs are a must for more communities to benefit in the project. Continuous improvement is the way forward.

- Description: Experience shows that the noise and sound quality in vehicles are often a recurring criticism. The bodies of modern vehicles consist predominantly of thin sheets of metal. It is hard to prevent the excitation of bending vibrations and the subsequent emission of disturbing noise while driving. The noise spectrum in a car that can be heard by the driver is from ”latent roar” to ”chattering” noise of the body and engine. In automotive vehicles damped materials, especially plastics or materials made from sheet metal and surface damping treatments, are used. Those have high internal energy losses and damp sound oscillatory systems found in the body or interior of cars. A further advantage of such treated components is that they are applied to existing components working over wide temperature and frequency ranges. Many companies provide such ”sound-absorbing compounds”. The requirements for these damping materials are high temperature-resistance, water repellence, fuel and oil-resistance and good adhesion to the base material [17]. The acoustic properties, especially the damping of the plate vibrations through rubber are of interest. the question arises how can the damping coeficient of coated metal sheets can be measured and secondly, by how much the road noise is reduced when built-in sheets are coated with a known damped material. With the Oberst Bar Test Method (named after Dr. H. Oberst) the properties are determined of the internal damping materials that can be used to simulate mechanical constructions to determine damping of larger surfaces. This method describes a laboratory test procedure for measuring the mechanical properties of damped materials. A block diagram of the test system consisting of a damped material bonded to a vibrating cantilever steel bar is shown in figure 2.1. This method is useful for testing materials such as metals, enamels, ceramics, rubbers, plastics, reinforced epoxy matrices and wood. In addition to damping measurement, the test allows for the determination of the Young’s modulus E of the material. E is calculated from the resonance frequency of a given mode and from the physical constants of the bar. By associating the damping factor with the Young’s modulus, a complex quantity is defined which is called the Complex Modulus of Elasticity. Measurements of dynamic mechanical properties are also useful in the research on the molecular structure of materials.

The study employed qualitative research techniques and data was obtained through semi-structured interviews with 40 small-scale farmers at Dzindi smallholder irrigation scheme.Irrigation control, high yielding crop varieties (HYVs), drought resistant crop varieties, drip irrigation are among a host of adaptation strategies successfully employed by farmers at Dzindi. These strategies have been effective in giving the farmers a lifeline in terms of household food supply and income.However, lack of funding, modern infrastructure and equipment has hampered adaptation efforts at the scheme. This has been compounded by lack of support from the Government. Government seemingly has not done enough to capacitate and assist famers to adapt to climate change.

- Description: Adolescents have become focal points of discussions and debates regarding sexuality and reproductive health matters. However, little research has been done particularly in South Africa to examine their knowledge concerning abortion and emergency contraception. Research indicates that a substantial proportion of adolescent pregnancies are unintended or unwanted. Abortion and emergency contraception are both time-sensitive services. Thus having accurate and comprehensive knowledge about both abortion and emergency contraception is pivotal, in the case of unintended or unwanted pregnancy or when engaging in unprotected sex or experiencing contraceptive failure that could lead to pregnancy. The 1994 International Conference on Population and Development (ICPD) defined reproductive health rights for both men and women as the right to "decide freely and responsibly the number, spacing and timing of their children and to have the information and means to do so" (p. 60). That is, men and women should "have the right to make decisions concerning their reproduction free of discrimination, violence and coercion" (ICPD, 1994, p.60). Based on these definitions, it is rather evident that comprehensive and accurate knowledge are at the core of one's ability to make an informed consent. This is confirmed by Adler's (1992, p. 289) definition of informed consent or choice "a) access to sufficient information b) understanding the information c) competence to evaluate potential consequences d) freedom to make a choice and e) the ability to make and express that choice". It is from this framework that this study emerged. The aim of this study was to examine adolescents' knowledge concerning abortion and emergency contraception. The participants were Grade 11 learners between the ages of 15-24 years from five different schools in the Buffalo City Municipality. A sample of 514 was achieved. Data were analysed using descriptive cross-tabulation, chi-square and qualitative methods where appropriate. The results revealed that most of the participants did not have sufficient accurate knowledge concerning the Choice on Termination of Pregnancy Act, consequences of legal abortion and emergency contraceptive pills to make informed decisions. Furthermore, data also revealed that the participants' schools playa role in their sexual activity, their knowledge about the Choice on Termination of Pregnancy Act and about emergency contraceptive pills. Although this method made it feasible for the researcher to make general assumptions, non-responses were one of the limitations of the study. Similar research in various municipalities/cities in and outside the Eastern Cape is recommended so as to increase further awareness concerning the level of knowledge that adolescents have about contraceptive pills particularly emergency contraceptive pills, the Choice on Termination of Pregnancy Act and abortion in general.

- Description: A vibrant and an efficient agricultural sector would enable a country to feed its growing population, generate employment, earn foreign exchange and provide raw materials for industries. The agricultural sector has a multiplier effect on any nation's socio-economic and industrial fabric because of the multifunctional nature of agriculture. The main objective of this study was to investigate how government expenditure on agriculture has affected economic growth in Zimbabwe from 1980-2009. The Log linear growth regression model was employed where gross domestic gross was the dependant variable and the explanatory variables are the factors which affect it which include government agricultural expenditure. The expenditures of government on agriculture were divided into three functions namely extension, credit assistance and R & D. The regression analyses were performed using Econometric-views 7 (E-views 7) statistical package. Regression was carried out on time series data for the period 1980 to 2009. The data was tested for stationarity and for autocorrelation. Problems of non stationarity of data were corrected by integrating the trending series. Results from the empirical analysis provide strong evidence indicating that agriculture is an engine of economic growth. The results from this study suggest that spending more on agricultural research and development can improve economic growth and ultimately reduce poverty. However, it can also be concluded that insufficient government agricultural expenditure on extension and credit assistance adversely affected economic growth in Zimbabwe, based on the results of the study. Global experience with pro-poor growth and empirical work spanning India, Benin and Malawi demonstrates the importance of agricultural expenditure for poverty reduction in poor rural areas, while also pointing to the need for complementary non farm sector growth. This study also proposes a simple methodology to estimate the agricultural spending that will be required to achieve the Millennium Development Goal of halving poverty by 2015 (MDG1) in Zimbabwe. This method uses growth poverty and growth expenditure elasticities to estimate the financial resources required to meet the MDG1. The study attempts to address a key knowledge gap by improving estimation of first MDG agricultural expenditure at country level.

- Description: The adoption of the Millennium Development Goal 1 (MDG1) of reducing the rate of poverty to half of the 1990-level by 2015, the advent of democracy in South Africa, among other things, have raised concerns over the potential role of the agricultural sector. There is a belief that the sector has the capacity to successfully reduce poverty among the rural masses and contribute to addressing the problem of inequality in South Africa. In line with that thinking, South Africa‘s agricultural sector has attracted considerable fiscal policy interest. For instance, South Africa‘s statistics show that public investments in agricultural development programmes have been growing. In spite of this, rural poverty is still a major concern on an overall basis. However, this might not be the case in the Eastern Cape Province and the situation might be different for each district municipality. This study assesses the linkages between public agricultural investment, agricultural growth and poverty reduction in the Eastern Cape Province. The study also addresses the question whether Eastern Cape Province is on course to meet several regional development targets. The study also aims to provide an estimate of the amount of agricultural investment required to attain the agricultural productivity growth rate which is sufficient to meet MDG1. The study reviewed the various theories of public spending, linkages between public investment and agricultural growth and how these components affect the incidence of poverty. The conventional wisdom that public expenditure in agriculture positively affects economic growth and this growth consequently reduces poverty was noted. The reviews also revealed that in many developing countries, the current level of public agricultural investment needs to be increased significantly for countries to meet the MDG1. This study employed the decomposition technique and growth elasticity of poverty concept to estimate the response of poverty to its key determinants. The size of public spending, prioritization of public spending and the intensity in the use of public funds emerged as important in increasing agricultural production. The relationship between government investment in agriculture and agricultural GDP shows iv that public funds were largely behind the province‘s success in increasing agricultural production throughout the period from 1990s to 2010. Agricultural spending went to sustainable resource management, administrative functions and then farmer support programme. Exceptional growth in the size of spending was recorded in respect to agricultural economic function, structured agricultural training, sustainable resource management and veterinary services. Overall output from the agricultural sector fluctuated, and the sector contributed less than 5 per cent to the total provincial GDP. Correlations between growth in agricultural sector and changes in the incidence of poverty in Eastern Cape show that during the period 1995 to 2000, increases in the agricultural GDP per capita may have failed to benefit the poor as poverty increased in all the reported cases.–However, for the period between 2005 and 2010, the situation was different and it was observed that increases in agricultural GDP per capita and were associated with reduction in the incidence of poverty. Growth elasticity of poverty (GEP) estimates reveal that agricultural GDP per capita was more important in reducing poverty in 5 out of the 7 district municipalities. Non-agricultural GDP per capita was only important in two district municipalities. It emerged that most of the district municipalities are not in a position to meet any of the regional set goals. This situation is largely attributable to the province‘s failure to boost agricultural production which is an outcome of low and inefficient public expenditure management, inconsistent and misaligned policies and failure to fully embrace the concept of pro-poor growth. Varied provisional estimates for the required agricultural growth rate and the increase in public spending on agriculture required in order to reach MDG1 were calculated for each district municipalities. All the district municipalities of Eastern Cape will need to increase public investment in agriculture for them to achieve MDG1.

All the district municipalities of Eastern Cape will need to increase public investment in agriculture for them to achieve MDG1.

- Description: This research study took as its point of departure the general state of underperformance of the majority of schools in South Africa. A review of the literature uncovered evidence that suggested that the state of school management in the majority of schools was in disarray. The problem was compounded by the poor quality and haphazard nature of support that District and Circuit Officials of the Education Department rendered to schools. I therefore saw the need to conduct a scientific investigation into how Circuit Teams could be assisted to support School Management Teams towards whole-school development. Against this background, I formulated the following primary research question to guide the study: “How can Circuit Teams effectively support School Management Teams of underperforming schools towards whole-school development?” The following secondary research questions arose out of this to provide further direction to the study: How can Circuit Teams assist School Management Teams to develop and implement their respective School Improvement Plans? How can Circuit Teams be assisted to develop, implement and monitor their Circuit Improvement Plans? What recommendations can be made to improve service delivery to the schools?. The primary aim of the research was therefore to design an action learning model that would enable Circuit Teams to support School Management Teams of underperforming high schools towards whole-school development. A qualitative research approach was adopted for this study, as it best suited the purpose of the research, and the philosophical assumptions of the researcher. In addition, I drew on a constructivist-interpretative and a critical theory paradigm to guide the design. I chose action research as the specific methodology for the study as, in line with critical theory it aims to empower people to facilitate social change and improvement at a local level. Purposive sampling was used to select four underperforming high schools in the same township within the Cape Town Metro, belonging to the same education Circuit and District Office to participate in the research. In addition, the members of the Circuit Team that serviced these schools were also brought on board as participants. In total, 40 people participated in the research: 4 members from the Circuit Team, 4 Principals, 8 Deputy Principals and 24 Heads of Department. Data were generated in the period January to June 2012 using structured, semi-structured and unstructured interviews, participant observation, and document analysis. Data were analysed by following the eight steps for analysing qualitative data identified by Tesch. An Action Research cycle consisting of the following five steps was followed with participants during the fieldwork, viz.: Identification of the problem; Designing the action plan; Implementing the action plan; Evaluating the action, and Reflection and lessons learnt. Two Action Research cycles emerged from the fieldwork. The first cycle dealt with assisting the schools and Circuit Team to construct their improvement plans. The main findings from this cycle were (1) that the Circuit Team did not function as a team, due to the autocratic management style of the Circuit Team Manager, and the plan of action to address the underperforming schools was not developed in a participative manner. In addition, the Circuit Team had no Circuit Improvement Plan in place with which to support the schools. (2) The schools did not receive the required support to prepare their School Improvement Plans, and although they were able to articulate their areas of support needed, none of them undertook the process of School Self-Evaluation and therefore did not have School Improvement Plans in place. The second action r esearch cycle dealt with the support that schools needed from the other pillars of the District Office to implement their intervention plans. Three themes emerged from this action research cycle: (1) The School Management Teams required capacitybuilding to manage their schools effectively, (2) teachers needed support to implement the curriculum, and (3) learners required assistance to achieve better results. As the outcome of the research, a spiral model consisting of three distinctive phases, each having several loops that describe the particular action that Circuit Teams and School Management Teams have to undertake was developed as the ultimate outcome of the research. The structure of the model was explained, and explicit guidelines for operationalizing it in practice were provided. Based on the findings and the construction of the model, a number of recommendations were put forward to guide future research and practice in the area of Circuit Team support to nderperforming schools. In conclusion, this research study contributed to the body of knowledge by exploring, investigating and describing the working relationship between Circuit Teams and School Management Teams, which until now has not been adequately covered in the existing literature and research. The study culminated in a theoretical model which can be used to improve this relationship permitting Circuit Teams to better support School Management Teams towards whole-school development. The action research design also allowed a more participative and democratic relationship to develop between the Circuit Team and the School Management Teams of the four schools, which is also an innovative idea considering the traditional hierarchic and autocratic approach which has been the norm in the past. Hopefully the findings of this study will encourage the emergence of democratic partnerships between Departmental officials and school management, leading to the empowerment and transformation of school management.

- Description: Several authors have put forward methods of using Artificial Neural Networks (ANN) to classify URLs as malicious or benign by using lexical features of those URLs. These methods have been compared to other methods of classification, such as blacklisting and spam filtering, and have been found to be as accurate. Early attempts proved to be as highly accurate. Fully featured classifications use lexical features as well as lookups to classify URLs and include (but are not limited to) blacklists, spam filters and reputation services. These classifiers are based on the Online Perceptron Model, using a single neuron as a linear combiner and used lexical features that rely on the presence (or lack thereof) of words belonging to a bag-of-words. Several obfuscation resistant features are also used to increase the positive classification rate of these perceptrons. Examples of these include URL length, number of directory traversals and length of arguments passed to the file within the URL. In this paper we describe how we implement the online perceptron model and methods that we used to try to increase the accuracy of this model through the use of hidden layers and training cost validation. We discuss our results in relation to those of other papers, as well as other analysis performed on the training data and the neural networks themselves to best understand why they are so effective. Also described will be the proposed model for developing these Neural Networks, how to implement them in the real world through the use of browser extensions, proxy plugins and spam filters for mail servers, and our current implementation. Finally, work that is still in progress will be described. This work includes other methods of increasing accuracy through the use of modern training techniques and testing in a real world environment.

An analysis of ionospheric response to geomagnetic disturbances over South Africa and Antarctica

- Description: The ionosphere is of practical importance for satellite-based communication and navigation systems due to its variable refractive nature which affects the propagation of trans-ionospheric radio signals. This thesis reports on the first attempt to investigate the mechanisms responsible for the generation of positive ionospheric storm effects over mid-latitude South Africa. The storm response on 15 May 2005 was associated with equatorward neutral winds and the passage of travelling ionospheric disturbances (TIDs). The two TIDs reported in this thesis propagated with average velocities of ∼438 m/s and ∼515 m/s respectively. The velocity of the first TID (i.e. 438 m/s) is consistent with the velocities calculated in other studies for the same storm event. In a second case study, the positive storm enhancement on both 25 and 27 July 2004 lasted for more than 7 hours, and were classified as long-duration positive ionospheric storm effects. It has been suggested that the long-duration positive storm effects could have been caused by large-scale thermospheric wind circulation and enhanced equatorward neutral winds. These processes were in turn most likely to have been driven by enhanced and sustained energy input in the high-latitude ionosphere due to Joule heating and particle energy injection. This is evident by the prolonged high-level geomagnetic activity on both 25 and 27 July. This thesis also reports on the phase scintillation investigation at the South African Antarctic polar research station during solar minimum conditions. The multi-instrument approach that was used shows that the scintillation events were associated with auroral electron precipitation and that substorms play an essential role in the production of scintillation in the high latitudes. Furthermore, the investigation reveals that external energy injection into the ionosphere is necessary for the development of high-latitude irregularities which produce scintillation. Finally, this thesis highlights inadequate data resources as one of the major shortcomings to be addressed in order to fully understand and distinguish between the various ionospheric storm drivers over the Southern Africa mid-latitude region. The results presented in this thesis on the ionospheric response during geomagnetic storms provide essential information to direct further investigation aimed at developing this emerging field of study in South Africa.

- Description: Reading development in the Foundation Phase (FP) is central to children’s success as they progress through school. However, evaluations in South Africa such as the Annual National Assessments (ANAs) and the Progress in International Reading Literacy Study (PIRLS) (2006) show that reading achievement in the Foundation Phase is low, especially for children learning with African languages as their home language. This thesis examines pacing and sequencing in three Grade 1 literacy classes where isiXhosa is the language of learning and teaching (LOLT). The research took the form of a case study, focusing on the teachers’ classroom practice and how they understand their practice. Documents related to reading development in the Foundation Phase are analysed with regard to pacing and sequencing, examining how the curriculum frames literacy for teachers in the Foundation Phase. The teachers’ understanding in relation to their social context is also an important part of this research. In the thesis the way in which the teachers sequence and pace learning is analysed, drawing on Bernstein’s notions of internal and external framing, and Bourdieu’s notion of the habitus. The intended curriculum and the implemented curriculum are then compared. The results confirm that in low socio‐economic status (SES) schools, the level of poverty has an impact on teaching practice. The results also show that pacing and sequencing are reliant on the degree of planning amongst teachers. The level of development amongst learners also plays a role in how teachers organise their practice in order to differentiate the teaching of reading for all learners. The understanding that teachers have about their teaching practice are layered and influenced by their experiences, history and memories as teachers. The thesis concludes that there is a need to develop teachers’ understanding of planning and organising the teaching of reading, especially when the learners are from poor communities and do not get support in the home. In order for teachers to improve their practice, it is important for them to have the opportunity to reflect on and understand their practice.

- Description: Low domestic saving rates make South Africa highly dependent on foreign capital inflows to fund higher investment levels. These inflows are highly volatile and may prove to be unsustainable in the long-run. This study analyses the determinants of private saving in South Africa, with specific reference to the decline in private saving rates that occurred at a time of higher economic growth prior to the 2008 global financial crisis. The Johansen cointegration method is used to estimate separate vector error correction models (VECM) in order to assess the effect of specific variables on both corporate and household saving. The results obtained that are common to both corporate and household savmg show that the govemment budget balance negatively impacts private saving rates though the offset is less than one. The real prime overdraft rate positively impacts private saving, although the result is small . The impact of real Gross Domestic Product (GDP) is positive. In recent years, however, private saving rates fell alongside higher economic growth, which may reflect a structural change in corporate saving behaviour. The results distinct to the corporate saving model show that commodity prices have a negative impact on corporate saving. This does not conform to a priori expectations, but is supported by the behaviour of these two variables in recent years. Foreign savings were found to impact negatively on corporate saving. This result is important, since the dependence of the South African economy on foreign capital inflows to fund higher investment levels is reflected by high current account deficits during recent periods of economic growth. Evidence of financial liberalization negatively impacting on private saving in South Africa due to the removal of borrowing constraints was found. A negative relationship was found between corporate saving and investment demonstrating that corporations have reduced levels of retained eamings for funding investment expenditures. The results distinct to the household saving model provide evidence of a negative wealth effect in South Africa, with rising housing wealth found to increase consumption. Evidence of households "piercing the corporate veil" in South Africa was found. Therefore, households view corporate saving behaviour as essentially being conducted on their behalf. This finding and the finding that the offset between the budget deficit and private saving is less than one suggest that counter-cyclical fiscal policy will be an important policy response for achieving higher domestic saving rates in South Africa.

- Description: In the 2011 Budget Speech, the Minister of Finance announced that South Africa would be introducing National Health Insurance. The Minister described the financing mechanisms under consideration for funding National Health Insurance. The Minister also referred to eight countries, namely Japan, South Korea, Taiwan, Chile, Colombia, Mexico, Thailand and Vietnam as examples of countries which had successfully implemented universal health coverage. These countries were selected for the purpose of the present research. The goal of this study was to analyse the health care financing mechanisms under consideration in South Africa to determine if they were in line with international trends and "best practice" in relation to South Africa's economic profile. To determine whether the economic situation in South Africa is comparable to the eight countries selected for the research, a high-level comparison was made of the economic profile of South Africa and the eight countries, based on certain demographic, macro-economic, health expenditure and health status indicators. The health care financing mechanisms used in the eight countries was also analysed. International trends suggested that health care should be financed primarily through pre-payment systems, that financing mechanisms should preferably be progressive in nature and that a large share of funding should be from government sources (albeit shared between general tax revenue and specific health care contributions). The financing mechanisms under consideration in South Africa reflect these norms. The health systems in the eight countries analysed all exhibited elements of "good performance" and also complied, to a large extent, with international trends, but the frnancing models used for funding health care in the eight countries were country-specific and could therefore not be compared directly or used to recommend a system for South Africa. Areas not addressed by this thesis include the implications of a centralised healthcare system, the implications of a single-payer system, the benefit package to be offered and its cost implications, the role of private healthcare providers and how the significant human resource scarcity and infrastructure backlogs will be addressed.

- Description: The objective of the research was to determine whether the changes made to the Income Tax Act, 58 of 1962 between 1996 and 2012, in respect of fringe benefits, allowances, deductions, tax tables and rebates, where these changes apply to individuals, have resulted in relieving the tax burden placed on individuals in South Africa. The research was conducted by means of a critical analysis of documentary data with specific reference to the Income Tax Act, annual amendments to the Income Tax Act, statistics relating to tax collections, the National Budget and the Annual Budget Speeches as tabled by the Minister of Finance. These sources were utilised to analyse the amendments to the Act that have taken place over the last sixteen years, where they impact on the tax liability of an individual. A hypothetical example incorporating all the variables identified in the analysis of the tax amendments was used to provide a detailed analysis of the tax payable by an individual on an inflation-adjusted year-on-year basis. The research found that, whilst personal income tax is still the largest contributor to the national budget of South Africa, its contribution has decreased from 40.2 percent in 1996 to 34.3 percent in 2010. This decrease is partly attributable to the extensive tax reforms undertaken by Government with respect to the tax tables, resulting in a reduction in the marginal tax rates and increased tax rebates which had the effect that the individual taxpayer (as illustrated in the hypothetical example) experienced a decrease in the average rate of tax. In contrast to this, the increase in the taxable income of the hypothetical taxpayer exceeded the average rate of inflation over the period. Furthermore, the actual revenue collected by the government from personal income tax has increased by approximately eleven percent per annum, which far exceeds the average inflation rate of 6.23 percent. The research indicated that this could be the result of the increase in the taxable value of fringe benefits, specifically medical aid contributions and company cars, as well as the inclusion of the full amount of allowances in taxable income and the limits placed on the deductions an individual may claim. The result is a broadening of the tax base of the individual taxpayer. Therefore, although the government may have achieved its goal of a fairer tax system, the amendments made to fringe benefits, allowances and deductions have resulted in an increase in the average taxable income of individuals.

An analysis of the judicial approach to the interpretation of tax avoidance legislation in South Africa

- Description: Tax evasion and avoidance costs South Africa billions of rand each year. This treatise examines the judiciary’s view and/or attitude to the dividing line between legitimate and illegitimate tax avoidance. It seeks to find out how South African courts have ultimately dealt with the old GAAR section 103(1). The treatise seeks to establish the role that the judiciary plays in tax avoidance and whether it has been pro-fiscus or pro-taxpayer in its deliberations of tax avoidance cases. The treatise focuses specifically on the judicial responses to the General Anti-avoidance Rule Section 103 of the Income Tax Act No. 58 of 1962. In order to show the judicial approaches and/or responses to tax avoidance in South Africa, a selection of income tax cases have been used to illustrate how the judges have interpreted the GAAR and whether they have been sympathetic to the tax payer or to the fiscus. The cases used in this study stem from the old GAAR section 103. There have not been important cases dealing with the new GAAR section 80A to 80L of the Income Tax Act. In the final analysis of this research it would seem that the effectiveness and scope of the GAAR depends ultimately on its interpretation by the courts. Many of the cases that have been decided under section 103 (1) have provided disappointing outcomes for SARS. However it is noteworthy that the courts which were previously taking a restrictive approach and were pro-taxpayer in their deliberations are beginning to take a different approach and are gallant in their interpretation of the GAAR. Judges are slowly abandoning the long standing judicial approach which was that taxpayers are entitled to arrange their affairs in any legal way in order to minimize their tax and are going further and examining the real substance and purpose of the transactions entered into by taxpayers as opposed to the form of the transactions. The Supreme Court of Appeal has now set a precedent which goes deeper and examines the true intention of parties in entering into transactions and does not tie itself to labels that parties have attached to their transactions. This recent judicial attitude and zeal exhibited by the courts will without a doubt hinder tax avoidance activity and strengthen the effectiveness and scope of the new GAAR sections 80A to 80L.

An analysis of the Libor and Swap market models for pricing interest-rate derivatives

- Description: This thesis focuses on the non-arbitrage (fair) pricing of interest rate derivatives, in particular caplets and swaptions using the LIBOR market model (LMM) developed by Brace, Gatarek, and Musiela (1997) and Swap market model (SMM) developed Jamshidan (1997), respectively. Today, in most financial markets, interest rate derivatives are priced using the renowned Black-Scholes formula developed by Black and Scholes (1973). We present new pricing models for caplets and swaptions, which can be implemented in the financial market other than the Black-Scholes model. We theoretically construct these "new market models" and then test their practical aspects. We show that the dynamics of the LMM imply a pricing formula for caplets that has the same structure as the Black-Scholes pricing formula for a caplet that is used by market practitioners. For the SMM we also theoretically construct an arbitrage-free interest rate model that implies a pricing formula for swaptions that has the same structure as the Black-Scholes pricing formula for swaptions. We empirically compare the pricing performance of the LMM against the Black-Scholes for pricing caplets using Monte Carlo methods.

A comparison will then be made between these liquidity ratios. The second objective is to illustrate that cash flow ratios are a better indication of liquidity of an entity than the traditional ratios. The traditional and cash flow ratios will illustrate the position of liquidity with information utilised from the various bankrupt companies’ financial statements, including the statement of financial position and statement of cash flows. Four years’ financial statement data will be used to illustrate the deteriorating liquidity positions of the companies.

- Description: The focus of this study is the Southern African Development Community (SADC) preventive diplomacy interventions in Lesotho in 1994, 1998 and 2007. The core aim of the study was to evaluate the efficacy of the SADC security mechanism (the Organ on Politics, Defence and Security (OPDS) in conflict prevention, management and resolution on the basis of the Lesotho experience. Data for this qualitative case study was collected through interviews and document analysis. The twenty four participants for the study were drawn from the SADC OPDS unit, Lesotho political parties, Civil Society Organisations (CSOs), Academics from the University of Botswana (UB) and the National University of Lesotho (NUL), retired Botswana Defence officers who participated in the Lesotho missions and office of the post-2007election dispute dialogue facilitator in Lesotho. Documents on the SADC Treaties, Protocols, Communiqués and interventions in other set ups were used to highlight its operational policies, mandate, structures, successes and challenges. Lesotho was chosen as a case study because SADC employed both non-coercive (SADC Troika and Eminent Person mediation, 1994 and 2007 respectively) and coercive measures (the 1998 military intervention). The findings of the study revealed that SADC as a regional body had its own successes and challenges. Different perceptions on the SADC interventions in Lesotho emerged mainly between the participants from the ruling party and the opposition parties. While the former commended SADC for successfully mitigating the calamitous effects of 1994, 1998 and 2007 post-electoral violence, the opposition parties viewed the regional organisations as engaged in illegal interference in the domestic affairs of the country to defend the incumbent governing party. It also emerged from the study that the SADC security mechanism has numerous structural and operational flaws. There were several unanswered questions revolving around the legality and mandate of some of the missions. For instance, no concrete evidence emerged as to whether the 1998 military intervention was authorised by the SADC. The study also revealed that SADC has learnt valuable lessons from the Lesotho missions. Some of the reforms which the SADC has introduced in the OPDS such as the establishment of the SADC Stand by Force, Early Warning structures, the Mediation Unit, and a panel of expert mediators emanated mainly from the Lesotho experiences. The study recommends that SADC needs to harmonise the efforts of its OPDS structures such as the Mediation Unit; the Troika; the Inter-State Defence and Security Committee (ISDSC); the Inter-State Politics and Diplomacy Committee (ISPDC) and the Summit of Heads of States and Governments for rapid, coherent and well coordinated interventions in future regional preventive missions. It is also recommended that SADC should focus on identifying and mitigating underlying causal factors such as underdevelopment; poverty; deprivation of freedoms, marginalisation and other forms of social stratifications and oppression in its preventive diplomacy missions if durable peace is to be achieved in Lesotho and any other future cases.

- Description: This research report examines the changing nature of the organisation of work, in particular, the production methods in the South African automotive industry. The competition in the local and global markets has increased significantly in recent years. The increased complexity of products and individuality of customers pose strong challenges for the automotive manufacturers, (OEM – Original Equipment Manufacturers), with regard to product Quality, Cost and Delivery. For these challenges, Volkswagen Group South Africa, has defined objectives that, when met, will contribute towards establishing it as a leading automotive brand. It is aligned to the Volkswagen Group AG, Strategy Mach18, increased vehicle production and the creation of long-term delighted customer base. To achieve these objectives, the Volkswagen Production System (VPS) is an imperative component of the Volkswagen Group South Africa (VWGSA) production strategy. The core elements consist of, “Cycle”, “Flow”, “Pull” and “Perfection”. These are the four fundamentals on which Lean Manufacturing is built, as first introduced and described by the Toyota Production System. Lean manufacturing is a whole-systems approach that creates a culture in which everyone in the organisation continuously improves the process and production. Volkswagen Group South Africa is facing increased competition in the South African and global marketplace. A search of the internet revealed that extensive research has been conducted into Lean manufacturing in South Africa. However, no research is noted with regard to the sustainability of Lean manufacturing at Volkswagen Group South Africa. The aim of this study is to analyse the sustainability of the lean manufacturing implementation at VWGSA.

- Description: Among the world‘s ecosystems, estuaries have the highest total economic value per hectare. They are dynamic coastal biomes that provide a host of different goods and services to the surrounding terrestrial and aquatic environments and the people who utilise them. These goods and services include, inter alia, nursery areas for marine organisms, harvested natural resources (such as fish, shell-fish, bait organisms, reeds and mangroves), flood attenuation, water purification, nutrient and sediment sinks, waste disposal, transport, aesthetic beauty and areas for swimming, boating and fishing. Assessing the condition of estuaries is difficult as their state can change depending on what is being measured. Assessments have been carried out on the health of estuaries in South Africa with the results of these studies being used as inputs to the process of assessing the minimum water supply requirements for each estuary (ecological reserve) in order to maintain or improve its functionality. These ecological reserve requirements are assigned using Resource Directed Measures (RDM). These measures, however, have been criticised for being highly complex and too costly to implement for all South African estuaries within a reasonable time period. Another concern is that the levels of demand for recreational goods and services provided by the estuary are not taken into account when assessing estuarine value. It is important to understand that the use of estuaries for recreational purposes is inextricably linked to their health and sound ecological functioning. Although South African estuaries have been quite well buffered from impacts until only very recently, their use and pressures have escalated faster than what conservation authorities and policy makers have been prepared for over the last couple of decades. There is thus mounting pressure on estuaries as recreational outlets, which, in turn, has led to their functional deterioration as well as deterioration in the quality of the recreational experience as a whole. One implication for management is that more and more trade-offs have to be made in an attempt to balance the conservation and recreational use of estuaries.
