- Description: The objective of this study was to determine the extent to which the finance function has evolved from being mere transactional – into one being more value-adding and business-partnering. The main focus of this study is on the role of finance as a business partner. Its main function is to add value to the business and the operations, and to offer the required support, in order for management to be able to make the right decisions. In this role, finance is regarded as part of the management team – and not just an external support function providing number ‘crunching’ – but a member that provides valuable input in the processes that the business follows. They become an in-house consultant for the business, thereby providing technical knowledge, which is aligned to the manner in which the business conducts its operations. The activities that are to be done by finance in this role comprise the following: Alignment of the functions of finance with those of the business, and what is thereby required; Providing information to the business on a timely basis; Providing information that assists and is relevant in the decision-making process of the business; Having a balance between providing governance support, as well as ensuring adequate control of the assets of the organisation. Reducing non-value adding activities that can be outsourced, such as standard reports, which can be developed and housed within a linked IT system. In order to be able to perform these activities effectively, there needs to be adequate support from the organisation’s IT environment, where standard templates can be developed, which are linked, and which lead to the availability of time for the analysis of the data. The resources also needs to have the required soft skills – of which communication and the ability to influence are important aspect – as there would be times when the people in operations would need to align their business decisions to the right finance decision – without becoming an obstruction to the business. A survey was carried out involving the accountants, whose role was to support the business in the South African environment, and which provided information on the following research questions: (i) Are finance professionals moving towards becoming business partners and away from transactional back-office work? (ii) What are the main reasons for the lack of transformation of the finance function? (iii) Is the size of the organisation a factor in its transformation? (iv) Does the fact that a company is a multinational or a South African organisation have any impact on the transition? The results of the survey were used to draw a conclusion on the extent of the change in the role of finance. The research concluded that there had been some change in the role that finance was performing in regard to the business. However, there were still areas where more could be done to move the change along, and to arrive at a position where finance becomes a full business partner.

- Description: The Expanded Public Works Programme (EPWP) has been seen by government as a poverty-alleviation initiative in which many South Africans receive training and temporary employment that assist them in enhancing their employability. This has been seen in many rural communities as assisting with development of the community. It has been emphasize that this programme boosts the local economy while at the same time providing much needed financial support to those that are faced with lack of community development and unemployment. The aim of this study was to investigate the impact of the programme on community upliftment, with particular reference to community perceptions of the programme and training that is offered within the programme itself. Challenges with the implementation and execution of the programme were explored, in order to develop recommendations that will enhance the effectiveness of the programme within the local municipality. The literature study included interviews with key informants involved directly with the programme in the local municipality. A descriptive research approach within a qualitative paradigm was adopted for the study. Data was collected mainly from secondary sources. The findings of the study indicate that the Expanded Public Works Programme is the main source of employment within the local municipality, benefiting not only the beneficiaries involved in the programme, but also the community as a whole. The beneficiaries in the local area are able to sustain their needs through participating in the programme, and the community becomes safer and cleaner, with income being brought into families by participants in the programme. However, the local municipality is not achieving its set targets, and there is evidence of a lack of skills development and misuse of the beneficiaries by the local municipality officials, which is causing the programme to be ineffective.

- Description: The health care system in South Africa is currently under strain and it does not cater for everyone's needs. This has left a gap in society whereby you will find that the poor citizens of the country are not being catered for in terms of getting access to adequate healthcare. With this existing gap, there are Non-Governmental Organizations (NGOs) in some of the poor communities in the country. These NGOs have volunteer caregivers who go around the community and taking care of the sick people. Research has often ignored these volunteer caregivers, this current research study investigated the experiences of these volunteer caregivers. The goals of the research study were to investigate the experiences of the caregiver, the motivations of the caregivers and the challenges that they encounter and how they cope with the challenges that arise while performing their caregiving duties. The study was based on the phenomenological paradigm. This paradigm believes that the subjective experience of the individual is an essential source of information. In-depth interviews were conducted with the four participants who took part in the study. An interview guide was utilised to help guide the interview process. Interpretive Phenomenological Analysis (IPA) was used in analysing the data. IPA is a way of analysing data, which investigates how a person, in a given setting understands an experience. The findings showed that the caregivers had both negative and positive experiences. They experienced the care recipients as being appreciative of them. However, they experienced the family members of the care recipients as being uncaring; financial constraints were also a negative experience. Several challenges were stated by the participants, including a lack of government support, alcohol abuse by the care recipients and challenging working conditions. The participants were motivated to volunteer as caregivers by a number of things. Altruistic motivation was the first, which included the love for the community and the poverty in the community. Reciprocity was another motivating factor, as well as religious duty and career advancement. In this research study there was one coping strategy that came out; the participants stated that they seek advice and consult with someone or go for supervision within the organization when they are faced with a difficult situation. The findings in the research study were similar to those found in previous research. One notably different finding was that in previous research, the caregivers have been found to abuse alcohol in order to cope with stress. However, in this research study, the care recipients are the ones who are abusing alcohol. The research recommends that the government assists the informal caregivers, either financially or with infrastructure.

- Description: Street trees are important foundations of urban sustainability due to the ecosystem services that they provide society and the environment. However, street trees are vulnerable to vandalism and damage, especially when small, which constraints the flow of benefits they provide and also increases the costs of planting programmes. Despite being a common phenomenon, there is limited knowledge regarding the extent of vandalism and the reasons for it. Here we seek to understand the causes and extent of street tree damage in eleven small Eastern Cape (South Africa) towns and to assess the perceptions of residents and officials. The condition of newly planted street trees was assessed in each town and residents were interviewed in the two towns with the highest number of newly planted street trees. Almost half (42%) of recently planted street trees were totally snapped, ranging between 0% and 63% per town. There was no difference in the prevalence of trees being snapped between those with protective structures and those without. Each town used different structures around newly planted street trees, but in only two towns were all the structures intact. The prevalence of damage declined with increasing trunk thickness and increasing town size. According to residents, boredom, misbehaviour, lack of appreciation of trees and collection for wood were the main factors for tree vandalism by people along with damage by livestock. Ward councillors recognised the presence of vandalism, but indicated that it was not a priority topic in their ward meetings. Suggestions by residents to prevent vandalism included: planting in sensible areas, re-designing the protective structures, re-locating livestock and engendering community participation and ownership in all aspects of street tree planting.

- Description: The aim of this study is to investigate the extent to which selected management accounting techniques are practised by small-medium enterprises (SMEs) in Nelson Mandela Bay. Management accounting techniques can be described as the information and methods management use for decision-making in order to operate the business more effectively. Management accounting research has focused on large companies over the years. Limited research exists with regards to the practises of management accounting techniques within SMEs and the extent to which it is used. It is widely accepted that SMEs are an important part of most economies and contribute significantly in economic terms. This study outlines the selected management accounting techniques, and highlights the importance of management accounting within SMEs. This study appropriately considered a quantitative method, by using a self-administered questionnaire for the primary objective of the study. The designated population, who was surveyed, included the financial manager, management accountant or skilled accounting staff members within SMEs. Purposive sampling was considered, which consisted of the database of Nelson Mandela Bay Chamber of Commerce, Business Partners and Transnet, all of which work closely with SMEs in Nelson Mandela Bay. The study obtained 53 responses from 126 SMEs targeted. However, only 50 responses were usable. The main findings of the study reveal that SMEs are neutral with regards to the usage of the selected management accounting techniques, which means that to some extent the selected management accounting techniques are used, and to another extent it is not used. Conclusions with regard to the extent to which SMEs use the selected management accounting techniques, cannot be generalised, and further research is recommended. However, this research can be used as a basis for future research.

- Description: The retention of knowledge workers has become an increasing challenge both locally and internationally. This study focusses on the factors contributing to the retention of knowledge workers at an Industrial Development Zone in the Eastern Cape. The aim of the study was to investigate the factors that would facilitate the retention of knowledge workers in the IDZ. This was explored through the employee value proposition framework which includes affiliation, career development, work content, compensation, company benefits, work-life balance and performance and recognition. The sample consisted of 30 employees from the IDZ from all business units. Three categories of employee levels were selected namely the executive managers, managers and specialists and professionals. Thematic analysis was used to analyse data which was gathered through semi-structured interviews. The literature reviewed explored the various retention strategies used by organisations. From the literature review it is realised that employee retention strategies vary from one organisation to another. In most cases they are very similar. Although this is the case, not all strategies will work for all organisations, each organisation requires preferred and unique strategies for its employees. The findings indicate that the majority of employees were satisfied with the employee value proposition dimensions in the organisation. The exceptional areas of satisfaction were retirement benefits, career development, performance recognition, relationships with colleagues, health benefits, relationships with direct manager or supervisor and relationships generally within the organisation. Areas of dissatisfaction were also raised on long service incentives, autonomy to do work, relationships with other business units and the performance review process. In order to retain employees at the IDZ, it is recommended that the organisation should focus on enhancing long service incentives. It is also recommended that employees should be given greater autonomy to do their work. Relationships with business units also need to be strengthened. Work-life balance of employees and performance review process also need to be revised.

- Description: The increasing popularity of Nigerian video-film, defined as the ‘Nollywood phenomenon’ (Barrot 2008, Haynes 2010, Adesokan 2011), has attracted recent interdisciplinary academic attention, now known as ‘Nollywood Studies’. The aesthetics and ideological approach of Nollywood video-film are often differentiated from those of the long-established and illustrious African Cinema. Films of Africa are, however, generally characterised by seemingly unique forms of the fantastic – an uneasy theme in scholarship on Nollywood. Although Nollywood video-film is commended by some scholars, its representation of the supernatural and the fantastic is often perceived to be demeaning. Considering the complexity of fantastic themes in creative arts of Africa, this study contributes to this field of study by positioning Nollywood as an interventionist artistic practice that subverts the division between art and popular culture. Further, it considers how this positioning could shift our thinking about what constitutes art and creative practice in Africa. The distinctions between art and popular culture have been inherited from particularly Western disciplines. A critical analysis of the fantastic in Nollywood could expand interpretations of the broader uses of new media and appropriation and develop the discourse on contemporary creative practices of Africa and the parameters of the art history discipline. I interrogate the visual language of the video-film medium through a discussion of other forms of artistic media such as photography, video art, and performance art. The fantastic themes, such as ‘magic’, ‘fetishism’ and violence, conveyed through new media open up a field of questions regarding contemporary social-political dynamics. The cultural value of Nollywood video-film is often based on who makes it. As a proletarian product, Nollywood has been underestimated as a ‘low’ form of culture. Its use of appropriated material connotes the complex dialectics that formulate class difference. I consider how a positioning of video-film as a creative practice could be complicated by the fact that it also operates as a theocentric implement that is used by churches to evangelise. Moreover, I examine how ‘epic’ films construct idyllic notions of ‘ethnicity’ based on dialectics of rational/irrational or real/fantastic. Nollywood video-film also creates images of fantastic spaces. In this thesis, I address concepts of space in Nollywood from which fantastic desire is constructed.

- Description: With a declining population of roughly 3000-5000 individuals in Africa, African wild dogs (Lycaon pictus) are one of the most endangered carnivores in the world. As the global human population expands, it is becoming increasingly unlikely that large portions of land will be set aside for conservation, especially in developing countries. Thus, recent wild dog conservation efforts in South Africa have concentrated on establishing a managed metapopulation. A metapopulation is a group of geographically isolated subpopulations of a species that are managed (using supplementation and harvesting) to mimic natural gene flow. The Great Fish River Nature Reserve (GFRNR) in the Eastern Cape Province of South Africa has been identified as a potential reserve to become part of the national wild dog metapopulation. My research aimed to conduct a feasibility assessment of the long-term (~ 25 years) success of a wild dog reintroduction into the GFRNR. This assessment included biological modelling of wild dogs and their expected prey, and determining the potential anthropogenic threats to wild dogs on the private and communal land surrounding the reserve. I used VORTEX population modelling and determined that the GFRNR is likely to have a wild dog carrying capacity of ~22 individuals. Using a 25-year modelling simulation, the most appropriate wild dog reintroduction scenario would be to reintroduce six females and four males initially and supplement the population with one female and two males in years 3, 10, 15 and 23. In addition, the harvesting/removal of one male and one female in years 10 and 20 would be required to ensure 100% population persistence and adequate genetic diversity. Kudu (Tragelaphus strepsiceros) and bushbuck (Tragelaphus scriptus) are expected to be the two most important prey species for reintroduced wild dogs in the GFRNR. Furthermore, wild dogs are likely to prefer the north-western and south-western sectors of the reserve because of the relatively high prey densities in these areas. However, regular monitoring of both the potential prey and the wild dog populations is essential to ensure persistence of the wild dogs and to prevent prey populations decreasing precipitously. Using structured questionnaire interviews (n = 128), I found that while neighbouring land owners and local communities were generally positive about the potential wild dog reintroduction (56 % of all respondents), several threats to wild dogs were identified along the reserve boundary and on the adjoining unprotected land. Some private landowners and members of rural communities around the reserve (34 %) stated that they would kill any wild dogs that dispersed onto their land. In addition, some respondents (8 %) admitted to believing in traditional uses for wild dog products (e.g. fur) which could result in the illegal killing of wild dogs outside of the GFRNR for traditional purposes. Poaching and the presence of unvaccinated domestic dogs on neighbouring land were also identified as being potential threats to a reintroduced wild dog population. However, such anthropogenic threats appear to be localised to the western and southern boundaries of the reserve. Therefore, by implementing preventative measures (such as anti-snare collars, anti-poaching patrols and vaccination against rabies and canine distemper) the likelihood of such threats occurring can be reduced. I conclude that the GFRNR can sustain a population of wild dogs and successfully contribute to South Africa‘s national metapopulation. An additional reserve will benefit the country‘s metapopulation by increasing the number of wild dogs available for translocation, thereby increasing genetic diversity and overall resilience (to environmental change, disease etc.) of South Africa‘s wild dog population. This will contribute towards the future conservation of this endangered species.

- Description: This study identified the media frames that dominate Thisday newspaper's coverage of China's engagement with Nigeria and relate these frames to frame sponsors, who articulate and contest these framings. Frame analysis is applied to a sample of 40 news, feature and opinion articles between the sample period of 1 November 2011 and 31 December 2012. The study analysed media content from Thisday newspapers, drawing on the four dimensions of frames identified by Entman: define problems, diagnose causes, evaluate causal agents and their effects, and recommend treatment (Entman 1993). Using an inductive approach to frame analysis, the study identified two overarching mega frames, contested among the ruling elites who sponsor their views on China in the media, which define China's engagement with Nigeria; partner/role model and predator. The two mega frames mirror the broad characterisation prevalent in the academic literature on China in Africa. The primary partner/role model mega frame constructs China's engagement with Nigeria as a mutually beneficial economic partnership while on the other hand the predator mega frame constructs it as unequal and exploitative. The study identified the activities of frame sponsors who are articulating and promoting their views on China's engagement with Nigeria in the media as primarily responsible for these framings. The study also identified the activities of frame sponsors (ruling and economic elites) was key to the exclusion of ordinary peoples' voices, civic organisations, trade unions and human rights organisation in the text. However, the study also attributes the exclusion of ordinary voices, human rights, democracy and civic engagements in the text to the weakness of Thisday journalism in mediating the framings of China being promoted and articulated by elite frame sponsors. This is, however, symptomatic of the fault lines of journalism practice in Nigeria.

- Description: Artificial Neural Networks (ANNs) have been used in many fields for a variety of applications, and proved to be reliable. They have proved to be one of the most powerful tools in the domain of forecasting and analysis of various time series. The forecasting of TCP/IP network traffic is an important issue receiving growing attention from the computer networks. By improving upon this task, efficient network traffic engineering and anomaly detection tools can be created, resulting in economic gains from better resource management. The use of ANNs requires some critical decisions on the part of the user. These decisions, which are mainly concerned with the determinations of the components of the network structure and the parameters defined for the learning algorithm, can significantly affect the ability of the ANN to generalize, i.e. to have the outputs of the ANN approximate target values given inputs that are not in the training set. This has an impact on the quality of forecasts produced by the ANN. Although there are some discussions in the literature regarding the issues that affect network generalization ability, there is no standard method or approach that is universally accepted to determine the optimum values of these parameters for a particular problem. This research examined the impact a selection of key design features has on the generalization ability of ANNs. We examined how the size and composition of the network architecture, the size of the training samples, the choice of learning algorithm, the training schedule and the size of the learning rate both individually and collectively affect the ability of an ANN to learn the training data and to generalize well to novel data. To investigate this matter, we empirically conducted several experiments in forecasting a real world TCP/IP network traffic time series and the network performance validated using an independent test set. MATLAB version 7.4.0.287’s Neural Network toolbox version 5.0.2 (R2007a) was used for our experiments. The results are found to be promising in terms of ease of design and use of ANNs. Our results indicate that in contrast to Occam’s razor principle for a single hidden layer an increase in number of hidden neurons produces a corresponding increase in generalization ability of ANNs, however larger networks do not always improve the generalization ability of ANNs even though an increase in number of hidden neurons results in a concomitant rise in network generalization. Also, contradicting commonly accepted guidelines, networks trained with a larger representation of the data, exhibit better generalization than networks trained on smaller representations, even though the larger networks have a significantly greater capacity. Furthermore, the results obtained indicate that the learning rate, momentum, training schedule and choice of learning algorithm have as much a significant effect on ANN generalization ability. A number of conclusions were drawn from the results and later used to generate a comprehensive set of guidelines that will facilitate the process of design and use of ANNs in TCP/IP network traffic forecasting. The main contribution of this research lies in the identification of optimal strategies for the use of ANNs in forecasting TCP/IP network traffic trends. Although the information obtained from the tests carried out in this research is specific to the problem considered, it provides users of back-propagation networks with a valuable guide on the behaviour of networks under a wide range of operating conditions. It is important to note that the guidelines accrued from this research are of an assistive and not necessarily restrictive nature to potential ANN modellers.

- Description: Chrysoblephus puniceus is an over-exploited linefish species, endemic to the coastlines off southern Mozambique and eastern South Africa. Over-exploitation and habitat loss are two of the biggest threats to the sustainability of fisheries globally. Assessing the genetic stock structure (a prerequisite for effective management) and predicting climate related range changes will provide a better understanding of these threats to C. puniceus which can be used to improve the sustainability of the fishery. Two hundred and eighty four genetic samples were collected from eight sampling sites between Ponta da Barra in Mozambique and Coffee Bay in South Africa. The mitochondrial control region and ten microsatellite loci were amplified to analyse the stock structure of C. puniceus. The majority of microsatellite and mtDNA pairwise population comparisons were not significant (P > 0.05) although Xai Xai and Inhaca populations had some significant population comparisons for mtDNA (P < 0.05). AMOVA did not explain any significant variation at the between groups hierarchical level for any pre-defined groupings except for a mtDNA grouping which separated out Xai Xai and Inhaca from other sampling sites. SAMOVA, isolation by distance tests, structure analysis, principle component analysis and spatial autocorrelation analysis all indicated a single population of C. puniceus as being most likely. The migrate-n analysis provided evidence of current driven larval transport, with net migration rates influenced by current dynamics.Two hundred and thirty six unique presence points of C. puniceus were correlated with seasonal maximum and minimum temperature data and bathymetry to model the current distribution and predict future distribution changes of the species up until 2030. Eight individual species distribution models were developed and combined into a mean ensemble model using the Biomod2 package. Winter minimum temperature was the most important variable in determining models outputs. Overall the ensemble model was accurate with a true skills statistic score of 0.962. Binary transformed mean ensemble models predicted a northern and southern range contraction of C. puniceus' distribution of 15 percent; by 2030. The mean ensemble probability of occurrence models indicated that C. puniceus' abundance is likely to decrease off the southern Mozambique coastline but remain high off KwaZulu-Natal. The results of the genetic analysis support the theory of external recruitment sustaining the KwaZulu Natal fishery for C. puniceus. While the high genetic diversity and connectivity may make C. puniceus more resilient to disturbances, the loss of 15 percent; distribution and 11 percent; genetic diversity by 2030 will increase the species vulnerability. The decrease in abundance of C. puniceus off southern Mozambique together with current widespread exploitation levels could result in the collapse of the fishery. A single transboundary stock of C. puniceus highlights the need for co-management of the species. A combined stock assessment between South Africa and Mozambique and the development of further Marine Protected Areas off southern Mozambique are suggested as management options to minimise the vulnerability of this species.

- Description: It is currently hypothesised that the chokka squid (Loligo reynaudi) consist of a single stock. This was tested through a spatial comparison of the morphology of this species. Forty three morphometric characters were measured from 1079 chokka squid collected from three regions: the south coast of South Africa, the west coast of South Africa, and southern Angola. While no significant differences were found for the hard body parts, results from discriminant function analyses showed the soft body morphometric characters from each of the three regions differed, with an overall correct classification rate of 100% for males and 99% for females in all three regions. Due to the existing model being used to assess the resource currently being updated it was not feasible to apply this model to the area-disaggregated data from this study. Rather, the CPUE trends and catches from the area-disaggregated data were compared against those of the area-aggregated data, as a first attempt to discern any appreciable differences which would suggest the use of disaggregated data in future assessments. Both the trawl and jig CPUE trends from the area-disaggregated analysis differed only slightly from those of the area-aggregated data. Similarly, the spring and autumn biomass trends for the main spawning area (east of 22°E) followed the same trends as for the full area. It is therefore concluded that there is currently no need to assess the resource on an area-disaggregated basis.

- Description: The Enemy Release Hypothesis (ERH) predicts that when plant species are introduced outside their native range there is a release from natural enemies resulting in the plants becoming problematic invasive alien species (Lake and Leishman 2004; Puliafico et al. 2008). The release from natural enemies may benefit alien plants more than simply reducing herbivory because, according to the Evolution of Increased Competitive Ability (EICA) hypothesis, without pressure from herbivores more resources that were previously allocated to defence can be allocated to reproduction (Blossey and Notzold 1995). Alien invasive plants are therefore expected to have simpler herbivore communities with fewer specialist herbivores (Frenzel and Brandl 2003; Heleno et al. 2008; Heger and Jeschke 2014).

- Description: Many of these poems, although written in English, are inspired by Sepedi idioms and proverbs. Some invoke township and village life, others the observations and questions that come from writing poetry and experiences of travelling to different countries to read my poems. Others dwell on the political transformation in South Africa, or its absence, and on my own spiritual transformation.

- Description: The role of institutions – economic freedom – is a critical determinant of economic growth, yet the global distribution of economic freedom is skewed. Economic freedom focuses on personal choice, the ability to make voluntary transactions, the freedom to compete and the security of property rights. The SADC is attempting to alleviate poverty and achieve sustainable development and economic growth. This thesis illustrates that economic freedom, in aggregate, and on an individual component basis, drives economic growth. The annual data for the 12 SADC counties from 2000 to 2009 are used to construct a panel data model to conduct the empirical analyses. Cross-sectional effects, as well as time (period) effects, are valid; and thus, a two-way error-component model is estimated. The Hausman test showed the regressors to be endogenous and correlated with the error term. The Pesaran CD test, suitable for dynamic panels, determined that cross-sections are interdependent; and the cross-correlation coefficient indicated a relatively weak, yet substantial, correlation. The LSDV two-way error-component model is re-estimated using the Driscoll and Kraay standard errors and time-demeaned data to correct for cross-sectional dependence. Given the endogeneity between the idiosyncratic disturbance term and the regressors, the presence of heteroskedasticity and serial correlation, as well as the interdependence amongst the cross-sections, the econometric model is then estimated using the two-step system general method of moments with forward orthogonal deviations – instead of differencing. The results meet all the post-estimation diagnostic requirements: the Arellano and Bond test for second-order serial correlation fails to reject the null hypothesis of no autocorrelation; theSargan test for over-identification fails to reject the null hypothesis that the over-identification restrictions are valid, and the difference-in-Hansen test fails to reject the null hypothesis that the instrument subsets are strictly exogenous. The empirical results confirm the a priori expectations. Economic freedom is a positive and significant driver of economic growth. Investment and economic openness are positively related to growth, whereas government debt decreases growth. Government consumption is an insignificant driver of a country’s growth. The Granger causality test confirmed the direction of causality; economic freedom precedes economic growth; and it is possible for the SADC to improve their growth rates by becoming economically freer. The coefficient of adjustment derived from the error-correction model indicates that the dynamic system takes approximately two years to adjust to the long-run structural level. The Koyck Transformation indicates that the relationship between economic freedom and growth is intertemporal, requiring a lag structure. An impulse-response function shows that a permanent, positive ‘shock’ to economic freedom results in an increase in economic growth, although the extent differs for each country, as well as for the different freedom components. The five individual economic freedom components are all highly significant and positive drivers of growth; however, the magnitude of the elasticity parameters varies. The causality amongst the components indicates that bidirectional causality is present. Therefore, improving economic freedom in one area improves economic freedom in another, creating a multiplier effect.

- Description: A widely held view is that export diversification constitutes an important component of export led growth, and poses a major challenge for many developing countries. Given this, the role of export diversification on economic growth warrants a fresh analysis in South Africa. The primary objective of this study is to determine the impact of export diversification on economic growth in South Africa. In this context, the study seeks to establish the relationship between export diversification, export stability and export growth. Initially, the study examines the extent and structure of export diversification in South Africa; it then empirically establishes the link between export diversification, export stability and export growth. Finally, it develops a model and investigates the effects of export diversification on economic growth in South Africa. As an attempt to fulfill the proposed objectives, this study uses quarterly data for the period 1980 to 2012 as well as data for 28 selected groups of commodities to investigate the effects of export diversification on economic growth in South Africa. Measures of export diversification and structural changes in exports in the context of South Africa were discussed. The findings of this study are that the Commodity Specific Cumulative Experience function showed that plots for manufactured commodities are shifted to the right indicating that the commodities are non-traditional in nature whereas, plots for primary commodities are shifted to the left. Results also indicated that South Africa relies more on traditional exports than manufactured exports. Various measures of export instability were used to calculate the export instability index in South Africa. The results of the study reveal that the South African export basket is slightly diversified, and the less diversified or primary commodities are associated with high instability VECM approach was used to allow us to establish the extent of influence of export diversification and other explanatory variables on economic growth. Consistent with other researchers, the study found that export diversification plays significant roles to economic growth in South Africa. A number of diagnostic checks were employed to validate the parameter evaluation of the outcomes achieved by the model. The model passed all the diagnostic checks. On the whole, the results to a larger extent painted a pictured that export diversification is important or drives economic growth in South Africa. Corroborating our findings with work of other scholars, we conclude that our results are complementary.

- Description: Empirical evidence and theoretical propositions suggest that financial development is strongly correlated to private investment because financial development positively affects investments by affecting capital accumulation, altering savings rate or by channelizing savings to various capital producing technologies. This study empirically investigated the impact of financial development on private investment in South Africa using quarterly data for the period 1994/01 to 2011/04. This study assess whether the theoretical and empirical propositions can be supported in South Africa. Cointegration tests using the Johansen approach (1988) were conducted to examine if there is a stable relationship in the level of private investment and financial development in South Africa. As a proxy for financial sector development, credit to private sector as per cent of GDP and stock market development were employed. Other variables that affect investment such as real interest rates and real GDP were also included in the model. Results of the study indicate that stock market development and real GDP have a positive relationship with private investment. Bank credit to the private sector however showed a negative relationship with private investment. A negative relationship was also noted for the relationship between private investment and real interest rates.

- Description: This study examined whether or not financial intermediation can explain the variations in the savings-investment ratio in South Africa during the period 1990 to 2012. The study specifically tests the McKinnon Conduit Effect hypothesis which states that increasing interest rate raises the capacity of financial savings via financial intermediaries based on data from South Africa. Apart from informal graphical test, this study employed formal tests such as the Augmented Dickey-Fuller and Phillips Perron stationarity tests to test the properties of the variables considered, including interest rates, for stationarity. In order to ascertain the long-run and short-run dynamics between its variables, the Johansen co-integration test is utilized, while the Error Correction Mechanism is also employed. Results from the study state that financial assets (a proxy for financial intermediation), income and real interest rate all positively impact the savings-investment ratio. Additionally, short-run analysis results showed that income, financial assets and real interest rates positively influence the savings-investment ratio. Real interest rates were seen as being both positive and statistically significant. Therefore the study recommended that the financial services sector and the South African Reserve Bank (SARB) should work together as this will result in the improvement of efficiencies in price discovery with regards to bank charges, access to banking facilities and the timely provision of services in order to encourage savings (for investment purposes) in the South African economy.

- Description: South Africa is a country faced with immense challenges, such as poverty, as a result of high levels of unemployment. Poverty reduction has become an international phenomenon in view of high levels of poverty in most under-developed and developing countries. From 1994, the South African Government implemented various income generating projects amongst other programs aimed at alleviating Poverty reduction initiatives in South Africa mostly come from government and civil society structures, or non – governmental organisations (NGO) with the aim of changing the living standards of the poor so that they can at least meet their basic needs, such as food, shelter and clothing. This study seeks to explore the impact of income generating projects funded by the Department of Economic Development in the Sisonke District at UMzimkhulu, focussing on the efforts the Paninkukhu co-operative. The study is important because of the high levels of poverty. South Africa (SA) is a country faced with the challenge of poverty as a result of the high levels of unemployment. The research method chosen for the study included a qualitative and quantitative research approach where data was collected through the use of interviews and a questionnaire. The findings of the study indicate a need to provide training to the project members on capacity building.
