- Description: The learning and analysis of algorithms and algorithm concepts are challenging to students due to the abstract and conceptual nature of algorithms. Algorithm animation is a form of technological support tool which encourages algorithm comprehension by visualising algorithms in execution. Algorithm animation can potentially be utilised to support students while learning algorithms. Despite widespread acknowledgement for the usefulness of algorithm animation in algorithm courses at tertiary institutions, no recognised framework exists upon which algorithm animation systems can be effectively modelled. This dissertation consequently focuses on the design of an extensible algorithm animation framework to support the generation of interactive algorithm animations. A literature and extant system review forms the basis for the framework design process. The result of the review is a list of requirements for a pedagogically effective algorithm animation system. The proposed framework supports the pedagogic requirements by utilising an independent layer structure to support the generation and display of algorithm animations. The effectiveness of the framework is evaluated through the implementation of a prototype algorithm animation system using sorting algorithms as a case study. This dissertation is successful in proposing a framework to support the development of algorithm animations. The prototype developed will enable the integration of algorithm animations into the Nelson Mandela Metropolitan University’s teaching model, thereby permitting the university to conduct future research relating to the usefulness of algorithm animation in algorithm courses.

- Description: The aim of the treatise was to provide a clear understanding of the changes to the trading stock provisions in the Income Tax Act. Various sections of the Act were covered and case law was reviewed with relevance in relation to this research project in order to gain a deeper understanding of the development of the trading stock provisions, thus bringing together the tax legislation and the case law principles. Emphasis was placed on the development of the trading stock provisions. The conclusion from this was that some of the amendments were merely textual in nature whilst others were driven by case law. There were instances where cases did not give rise to amendments but simply reinforced existing provisions by providing guidance and clarity by way of the judges’ interpretations of those provisions. The amendments relating to the trading stock provisions in the Act and the judges’ interpretation of the applicable case law have resulted in a comprehensive understanding of the treatment of trading stock.

- Description: Context-aware computing enables mobile applications to discover and benefit from valuable context information, such as user location, time of day and current activity. However, determining the users’ context throughout their daily activities is one of the main challenges of context-aware computing. With the increasing number of built-in mobile sensors and other input sources, existing context models do not effectively handle context information related to personal user context. The objective of this research was to develop an improved context-aware model to support the context awareness needs of mobile applications. An existing context-aware model was selected as the most complete model to use as a basis for the proposed model to support context awareness in mobile applications. The existing context-aware model was modified to address the shortcomings of existing models in dealing with context information related to personal user context. The proposed model supports four different context dimensions, namely Physical, User Activity, Health and User Preferences. A prototype, called CoPro was developed, based on the proposed model, to demonstrate the effectiveness of the model. Several experiments were designed and conducted to determine if CoPro was effective, reliable and capable. CoPro was considered effective as it produced low-level context as well as inferred context. The reliability of the model was confirmed by evaluating CoPro using Quality of Context (QoC) metrics such as Accuracy, Freshness, Certainty and Completeness. CoPro was also found to be capable of dealing with the limitations of the mobile computing platform such as limited processing power. The research determined that the proposed context-aware model can be used to successfully support context awareness in mobile applications. Design recommendations were proposed and future work will involve converting the CoPro prototype into middleware in the form of an API to provide easier access to context awareness support in mobile applications.

- Description: University sustainability is a field of research that has been gaining increased interest in recent years. The reduction of environmental impact has become a strategic objective of universities globally. Universities have been prompted to take necessary action to ensure that their environmental impact is at a minimum. The environmental component of sustainability deals with the current conservation of the earth’s natural resources so that future generations can also have access to them. Human beings, due to their increasing needs, are accountable for the exploitation of natural resources. They are regarded as the main contributors to imbalances in the natural systems. Environmental concerns such as global warming, deforestations, disposal of wastes, and ozone reduction are the outcomes of the damage caused by humans on the environment. The aim of environmental education is to acquire remediation of the environment by making individuals aware of the environment and by educating them about how to live a more sustainable lifestyle. Environmental awareness is perceived as knowledge of the factors that affect the environment and having sensitivity towards the environment. Higher Education Institutions (HEIs) bear the responsibility of educating individuals about environmental issues since they provide education to future leaders in society who may have an influence on future conditions in the environment. Social media are capable of delivering information to a large spectrum of audiences at a low cost. The Pew Internet American Life Project reported that the number of adults who utilise social media has increased by 57 percent from 2005 to 2011. Several environmental activist organisations utilise social media to carry out environmental awareness campaigns. In this study two environmental awareness campaigns which were powered by social media were conducted to improve environmental awareness of individuals in a higher education environment. A Social media Model for ENvironmental Awareness (SMENA) was developed to facilitate the environmental awareness campaigns. The SMENA includes a website, social media as well as theoretical guidelines for creating environmental awareness campaigns, and for using social media for environmental awareness campaigns. A case study at the Nelson Mandela Metropolitan University (NMMU) was used to empirically evaluate SMENA. Students at the Department of Computer Sciences of NMMU were exposed to information about environmental issues through social media with the intention of improving their environmental knowledge and awareness. The SMENA website usability was rated positively and students enjoyed the blogs and information distributed by means of social media. The results of the study intervention were positive and showed that social media can be used to improve the environmental knowledge of students. This study provides a valuable contribution to both the field of environmental education and social media usage and acceptance. The guidelines and requirements for using social media to improve environmental awareness provided in this study can be used to assist educators and university management with addressing the problems of reducing environmental impact.

- Description: The South African businessman, Brand Pretorius, was born in the rural Orange Free State town of Steynsrus in 1953. Pretorius rose to prominence in the motor industry in South Africa and he retired in 2011 as Chairman of McCarthy Motor Holdings Limited the largest motor retailer in South Africa. Pretorius was selected for this psychobiographical study by means of purposive sampling, given his extraordinary business achievements. Pretorius is publicly recognised as one of South Africa’s most successful businessmen and leaders. Psychobiographical research typically takes into consideration the entire life of an individual with the aim of uncovering the story of an individual’s life through the lens of a particular theory. The aim of this study was to explore and describe the leadership development of Brand Pretorius juxtaposed against the model of authentic leadership proposed by Avolio and Luthans (2003). The life history of Brand Pretorius was studied using a qualitative single-case study design. The psychobiographical research method allowed the single-case to be studied spanning his entire career. Data was collected from both primary and secondary sources. Conceptual matrices were used to organise and integrate the findings against the model of authentic leadership. The use of multiple data sources increased the validity and reliability of the research process and findings. To ensure ethical integrity the researcher obtained informed consent from Pretorius. The findings of this research study indicate that Pretorius was able to successfully display the authentic leadership dimensions of self-awareness, internalised moral perspective, balanced processing, relational transparency and positive psychological capacities throughout the course of his career.

- Description: Service-oriented architectures (SOA) are being adopted by organisations in order to integrate disparate computational assets. A major hurdle they face is the decision on how to integrate the UI in an SOA. In addition, technological advances have allowed complex applications and complex user interfaces (UIs) to be realised and the increase in accessibility to computers enables a diverse population of users with different characteristics, preferences and needs to use these complex computer applications. Adaptive user interfaces (AUIs) have been proposed as a solution to cater for the differences in user traits by adapting the UI to meet the diverse needs of users. AUIs have, however, traditionally been developed using client/server architectures This research, therefore, set out to investigate how to develop an AUI using a service-oriented architecture (SOA). In order to successfully achieve the goal of this research, literature concerning SOAs was investigated to gain an understanding of SOAs. A literature review of AUIs was also undertaken to gain an understanding of AUIs. A model-based approach was used to develop a model for UI adaptation using knowledge gained in the literature reviews. The model generates different UIs depending on various users‘ inferred level of expertise. The model describes the interaction between AUI services that use design-time documents and run-time user-interaction to adapt the UI. A prototype of the model was implemented and evaluated using an evolution strategy devised to assess different aspects of the research. The evaluation strategy proved the following: The service components of the prototype adhere to SOA design principles; The implementation was effective based on software engineering metrics; and, The implementation was usable and did not negatively affect the performance of users. The successful implementation of the prototype provides evidence that the design of AUIs using SOA is feasible. This dissertation therefore makes a contribution to the development of AUIs using SOAs. The model could be used to provide UI adaptation for business software applications.

- Description: The number of international students studying abroad has doubled since the year 2000 and there are nearly five million students that are enrolled outside their country of origin. Over the past ten years new insights and approaches to the internationalisation of higher education have arisen which has influenced global research and education. Student mobility data is a component of internationalisation data. internationally mobile students are defined as students who have crossed international borders from their countries with the objective to study. Currently, there are several international organisations and projects that manage student mobility data from various Higher Education Institutions (HEIs) across the globe and report on this data. Two of these organisations are the Open Doors Report and Project Atlas. The organisations collect Data for Africa, although it is not as detailed and useful as the data provided about other countries. Since the number of students studying abroad has doubled since the year 2000, the amount of student mobility data kept by data collection agencies and HEIs has also increased. The data collected is not always accurate and this poses a data management problem. This study conducted a survey sent to international offices at various HEIs in South Africa and Africa. The survey investigates the current state of student mobility data management in HEIs. The survey results revealed that the international offices are currently dissatisfied with student mobility data management and will be willing to provide international student data to an African data repository. This study proposes the design and development of a web-based student mobility data repository, known as the African International Portal (AIP). The study identified design guidelines and requirements for a web-based data repository. The requirements, design and design guidelines were used to guide the development of the prototype. Heuristic evaluations were conducted on the prototype in order to identify any major usability problems. Findings revealed that the overall perceptions of the prototype were positive and can be attributed to the design considerations and guidelines used during the development phase. The prototype was evaluated using a full usability evaluation that determined the usefulness, effectiveness and efficiency of the prototype when users are in the process of managing student mobility data. The results indicate that the participants found the AIP to be an effective, efficient and a satisfactory means of managing student mobility data.

- Description: Today's mobile computing devices provide a convenient means to search for points-of-interest (POIs) such as restaurants and accommodation. Mobile Preference-Based Search Tools (PBSTs) allow users to identify POIs such as restaurants or accommodation most suited to their needs and constraints using a mobile device. These devices however, have several design constraints including limited screen space and hardware capabilities. Adaptive User Interfaces (AUIs) have been proposed to address these issues but have not been extensively applied to mobile PBSTs such as mobile tourist guides. In addition, AUIs possess several benefits and advantages over static (traditional) interfaces, which do not take a user's preferences, skill set and experience into account. Little research, however, has been conducted into identifying the potential benefits of AUIs for mobile preference-based searching (PBS). The aim of this research was to determine the extent to which an AUI could improve the effectiveness and user satisfaction of mobile PBS. A literature study was conducted to determine the benefits and limitations of existing mobile PBSTs and determine how these could be improved. The potential benefits of AUIs for mobile PBSTs and a mobile map-based visualisation system were identified. A suitable model for incorporating an AUI into a mobile PBST was identified. The requirements for a mobile PBST were combined with the potentially adaptable objects of a Mobile Map-based Visualisation (MMV) system to provide adaptation suggestions for POInter, an existing mobile tourist guide. A field study using POInter was conducted in order to measure the extent to which participants agreed with suggestions provided for adapting the information, interaction and visualisation aspects of the system. These results were used to derive adaptation requirements for A-POInter, an adaptive version of POInter. Using a model-based design approach, an AUI was designed and implemented for A-POInter. An extensive field study was then conducted to evaluate the usability of the adaptations provided by A-POInter. The quantitative and qualitative data collected from the evaluations allowed the usability of A-POInter to be determined. The results of the field study showed that the participants were highly satisfied with the usability and the usefulness of the adaptations provided by A-POInter. Conclusions and recommendations for future work based on the results of the research were then outlined to conclude the dissertation.

Mobile Preference-Based Search Tools (PBSTs) allow users to identify POIs such as restaurants or accommodation most suited to their needs and constraints using a mobile device. These devices however, have several design constraints including limited screen space and hardware capabilities. Adaptive User Interfaces (AUIs) have been proposed to address these issues but have not been extensively applied to mobile PBSTs such as mobile tourist guides. In addition, AUIs possess several benefits and advantages over static (traditional) interfaces, which do not take a user's preferences, skill set and experience into account. Little research, however, has been conducted into identifying the potential benefits of AUIs for mobile preference-based searching (PBS). The aim of this research was to determine the extent to which an AUI could improve the effectiveness and user satisfaction of mobile PBS. A literature study was conducted to determine the benefits and limitations of existing mobile PBSTs and determine how these could be improved. The potential benefits of AUIs for mobile PBSTs and a mobile map-based visualisation system were identified. A suitable model for incorporating an AUI into a mobile PBST was identified. The requirements for a mobile PBST were combined with the potentially adaptable objects of a Mobile Map-based Visualisation (MMV) system to provide adaptation suggestions for POInter, an existing mobile tourist guide. A field study using POInter was conducted in order to measure the extent to which participants agreed with suggestions provided for adapting the information, interaction and visualisation aspects of the system. These results were used to derive adaptation requirements for A-POInter, an adaptive version of POInter. Using a model-based design approach, an AUI was designed and implemented for A-POInter. An extensive field study was then conducted to evaluate the usability of the adaptations provided by A-POInter. The quantitative and qualitative data collected from the evaluations allowed the usability of A-POInter to be determined. The results of the field study showed that the participants were highly satisfied with the usability and the usefulness of the adaptations provided by A-POInter. Conclusions and recommendations for future work based on the results of the research were then outlined to conclude the dissertation.

- Description: Tax avoidance through interest deductions has been highlighted internationally as a concern with the effect of eroding tax revenues of countries, including South Africa (SA). The evident cause of this concern is what is termed base erosion and profit shifting (BEPS) mainly orchestrated by multinational companies using aggressive tax planning schemes. Although the concern continues to exist, comprehensive measures are in place in SA such as the anti-avoidance rules and exchange control regulations to mitigate the concern. The study was undertaken to analyse the legislation on interest deductions in terms of the Income Tax Act No 58 of 1962 (‘the Act’) with particular focus on anti-avoidance. A number of issues pertaining to the operation of the provisions in the Act; administrative challenges as well the possible exploitation of loopholes within the provisions were identified. Furthermore, a comparative analysis conducted against Australia and the United Kingdom indicated that the measures adopted in SA are relatively similar, if not ahead. The effect the anti-avoidance measures have on the economic growth was considered. The results were positive in that the measures do not counteract the pursuit of economic growth. Lastly, the study assessed the position of SA against the internationally recommended best practice on the subject matter and it became evident that opportunities exist to improve the current measures applied in SA to mitigate the BEPS risks through interest deductions.

- Description: Gross domestic product (GDP) is one of the most important economic performance indicators for any country that is closely watched by governments, businesses and financial communities. GDP often influences economic decisions and policy-making. These decisions are however often based on preliminary initial announcements by statistical agencies. The preliminary estimates are then revised as more comprehensive information becomes available. Therefore, it is important to ensure that the initial GDP announcements are unbiased, efficient and can be relied on. This study focuses on seasonally adjusted and annualised (qq) growth rates at constant prices for the following national accounts aggregates: GDP, gross domestic expenditure (GDE), final consumption expenditure by households and general government, gross fixed capital formation (GFCF), Exports and imports of goods and services, gross national income (GNI) and disposable income of households. The research methodology used is based on descriptive statistics and Ordinary Least Squares (OLS) regression estimations. The results of the study indicate that little confidence should be attributed to interpretations of the initially announced estimates for GDP, GDE, final consumption expenditure by households, GNI and disposable income by households. The study found evidence that suggests that the initial announcements are biased and inefficient. This implies that the initial announcements contain measurement errors that could be eliminated in order to become a better forecast of the final or true value. This further suggests a lack of expected reliability of existing and future initial announcements of the estimates. For short-term analysis the users of GDP data are encouraged to focus on different measures. It is also recommended that the statistical agents producing South Africa’s national accounts aggregates improve their statistical compilation processes. The agencies are also encouraged to conduct periodic revisions studies and make these available to the users.

- Description: Transfer pricing has become a very popular term in South Africa over the last few years, even more so since July 2013 when the Base Erosion and Profit Shifting (BEPS) Action plan was issued by the Organisation for Economic Co-operation and Development (OECD) and G20 (an international forum for the governments and central bank governors from 20 major economies). The OECD and G20 has issued the plan to address the perceived flaws in international tax rules, giving rise to profit shifting. Subsequently, the OECD has issued numerous reports and as a result has updated its 2010 Transfer Pricing Guidelines. Many countries have adopted these guidelines. However as South Africa is not an OECD member, there is no certainty that it will be adopted. The question is therefore: has the South African Tax legislation met the OECD guidelines and addressed the BEPS issue? Therefore, the objective of the research is to understand whether the current South African tax legislation is in line with the OECD Transfer Pricing Guidelines and BEPS Action Plan. The South African tax legislation provides South African taxpayers with no guidance as to how the OECD Transfer Pricing Guidelines needs to be implemented and interpreted. However, even though not legislation, the SARS practice note 7 and draft interpretation note on thin capitalisation provides taxpayers with a good basis of understanding the OECD Transfer Pricing Guidelines, as these documents provided by SARS is similar to that of the guidance in the OECD Transfer Pricing Guidelines, specifically relating to transfer pricing documentation. The issue that may result where the South African tax legislation is not in line with the OECD guidelines and the BEPS Action Plan is that Multinational Enterprises (MNEs) may use South Africa as the country to shift its profits to or from, thus effectively resulting in a loss to the Fiscus.

- Description: The aim of this treatise is to provide an analysis of the tax implications of making use of limited real rights in tax planning. In order to understand the tax implications of making use of limited real rights it is necessary to understand the nature and legal form of these rights. The importance of this understanding lies in the determination of the tax legislation applicable to the right in question, and the subsequent tax implications. The next step in working through an analysis of the tax implications of making use of limited real rights is therefore to define the scope of applicable legislation. This required an analysis of the scoping provisions of our tax legislation. Once the scope of applicable legislation had been defined, it was then possible to move onto an analysis of the application of the legislation identified to the various “stages” of limited real rights. The conclusion from this analysis is that the tax implications of making use of limited real rights are spread fairly broadly across several different pieces of legislation, and need to be carefully and fully considered when making a decision to make use of limited real rights in a tax planning strategy. The conclusion on the analysis of certain selected tax planning strategies that make use of limited real rights is that it is possible to make fairly substantial cash flow savings when deciding to implement a particular strategy which makes use of limited real rights. But, that use of these strategies is not without risk. For example, SARS may examine a particular strategy in terms of the “new” GAAR. The financial implications of the successful application of the GAAR may be disastrous to the taxpayer, and the tax planner will need to have considered and advised on the possibility of such a challenge from SARS. In addition, in some of the strategies, there are risks associated with the anticipated life expectancy of parties to the tax plan being shorter than anticipated. The conclusion is that the use of limited real rights in tax planning can be effective and provide savings, but that the use of such a strategy requires, inter alia, a very careful consideration of the interaction and application of our tax legislation to the strategy.

- Description: Enterprise Resource Planning (ERP) education can positively impact the success of an ERP implementation. Incorporating new tools and technologies into the learning process can potentially alleviate the evident problems with ERP education. Blended learning and e-learning environments both offer opportunities for improvement in education. However, there are various factors and components that need to be in place for such an environment to be successful. The aim of this research is to provide an ERP e-Learning Environment (ERPeL) that can assist with ERP education in terms of creating an integrated and comprehensive learning environment for novice ERP users. In order to achieve this aim, this study followed the Design-Based Research (DBR) methodology which is specific to educational technology research and was applied in iterative cycles where various components of the environment were evaluated by different participants. Quantitative and qualitative data was collected by means of field studies (interviews, focus groups and questionnaires). The proposed ERPeL underwent several iterations of feedback and improvement. In order to determine the success of e-learning, various critical success factors and evaluation criteria were investigated. Field studies were conducted in order to validate the theory in a real-world context. An initial field study was conducted with third year Nelson Mandela Metropolitan University (NMMU) students who were enrolled in the 2014 ERP systems’ module in the Department of Computing Sciences. Many of the problems identified in theory were found to be prevalent in the real-world context. One of the DBR process cycles involved the implementation of specific components of the ERPeL at the Developing and Strengthening Industry-driven Knowledge-transfer between developing Countries (DASIK) introduction to ERP systems course. Participants were either NMMU students, academic staff or industry delegates. The components evaluated included videos, learning content, badges, assessment and the SYSPRO Latte m-learning application. Additional components of a leader board, live chats, peer reviewing, expert reviews, user generated content, consultancy with experts and SYSPRO ERP certification were implemented in the subsequent cycle where participants were 2015 third year NMMU ERP systems students. The criteria used to evaluate the success of the ERPeL and its e-learning components were adapted from literature and a new set of evaluation criteria for e-learning was proposed. The ERPeL is made up of Moodle, the SYSPRO ERP System, the SYSPRO e-Learning System, the SYSPRO Latte m-learning application, learning content and components. Overall the ERPeL was positively received by the various sample groups. The research results indicate that the use of an e-learning environment for ERP systems was positively received. The most positive aspects reported were the implementation of e-learning components such as the interactive videos, simulations and m-learning. In support of this Masters dissertation, the following three papers have been published and presented at two local conferences and one international conference: 1. SACLA 2014, Port Elizabeth (South Africa); 2. SAICSIT 2015, Stellenbosch (South Africa); and 3. IDIA 2015, Zanzibar (Tanzania).

- Description: The conventional approach to increasing economic growth - increasing inputs, such as labour and capital, is not always possible. The wider, fundamental sources of economic growth need to be considered too. Foreign aid is a temporary lifeline and does not spur economic growth. Conversely, financial assistance negatively affects growth and can hamper development prospects. Economic freedom and economically freer countries have been associated with higher growth rates, higher per capita incomes, greater volumes of trade, prosperity and overall wellbeing. By improving their economic freedom, deregulating the economy and allowing economic freedom to prosper, countries can experience sustained GDP growth. Previous studies have shown that economic freedom and economic growth are exponentially related - and that by initially becoming freer, countires can increase their growth rates at higher rates. The main objective of the SADC is to achieve development and economic growth, to alleviate poverty and enhance the standard and quality of life for the peoples of Southern Africa. The SADC is attempting to achieve economic integration through macroeconomic convergence. A number of macroeconomic variables have been set to act as primary indicators. These include inflation, fiscal balance, public debt and the current account balance. By introducing the concept that economic freedom can lead to higher growth rates and being able to identify economic freedom, it makes it possible to investigate how the SADC can achieve its set goals by becoming freer. By investigating individual components that constitute the overall freedom index, it becomes possible to establish the relationship that exists between this viriable and economic growth. This will illustrate where deregulation and freedom are most effective and where policy decisions need to be highlighted. The 2008 economic crisis revealed that countries that decreased their economic freedom have fared worse than countries allowing freedom to prosper. Government fiscal stimulus has had no positive impact on growth rates; the negative effects of reducing economic freedom will onlky be fully seen in future years. However, the majority of the SADC countries showed a relatively strong fiscal stance during the recession. This study established whether that a positive relationship between economic freedom and economic growth in the SADC. Secondly, the direction of causality that economic freedom leads to economic growth. The findings reveal that economic freedom fosters economic growth in general, and for the SADC in particular. Empirical evidence has been found for the SADC; and the implications of becoming freer are more fully explained.

- Description: South Africa relies heavily on fossil fuels, particularly coal, to generate electricity and it is a well known fact that the use of fossil fuels contributes to climate change, as it produces greenhouse gases (GHGs). In fact, internationally South Africa is the 17th highest emitter of GHGs (Congressional Research Service (CRS), 2008). Coupled with the environmental consequences of fossil fuel use, South Africa has a further responsibility of addressing the inherited backlog of electricity provision to the rural, and previously disadvantaged communities. In an attempt to address these two problems, the government issued the White Paper on Renewable Energy. In this paper, renewable energy alternatives are proposed to replace a portion of traditional electricity generating methods. Concentrator photovoltaic (CPV) energy generation is one such renewable option available to government. CPV uses optic elements (such as lenses) to concentrate sunlight onto solar cells. Owing to the light being concentrated, the cells in CPV use less semiconductor material, which makes them more efficient in comparison to conventional photovoltaic (PV) cells. CPV is a technology that operates well in regions with high solar radiation. As such, South Africa is particularly well suited for this technology, with average solar radiation levels ranging from 4.5 to 6.5 05 ℎ/. CPV is also well suited for off-grid application, which addresses electricity demand in remote rural areas. This study is an economic project analysis of the installation, operation, maintenance, and decommissioning of CPV technology in a rural area in the Eastern Cape, South Africa. The study area chosen for this purpose is the Tyefu settlement in the Eastern Cape. Tyefu was deemed ideal for this type of analysis due to four characteristics. Firstly, Tyefu is a remote rural settlement at the end of the national grid. Secondly, the community is very poor and previously disadvantaged. Thirdly, many households are without Eskom generated electricity. Lastly, the study area is located in an area with ideal irradiance levels for CPV. Two methods of economic project analysis are applied to this case study, namely a costbenefit analysis (CBA) and a cost-effectiveness analysis (CEA). Additionally, two types of CBA are performed, namely a private CBA and a social CBA. The private CBA evaluates the Tyefu electrification project from a private investor's perspective and the social CBA evaluates the project from society's point of view. The CEAs carried out compare the costeffectiveness of the traditional PV technology to that of CPV in terms of private and social costs. The private costs and benefits of the CPV project were identified and valued in terms of market prices. Then, this cost benefit profile was used to calculate net benefits which in turn were discounted to present values using a private discount rate of 6.42 percent. Three decision making criteria were generated, namely the net present value (NPV), the internal rate of return (IRR) and the benefit cost ratio (BCR). Sensitivity analysis was carried out by varying the private discount rate and the bidding price. The social costs and benefits of the CPV project were identified and valued in terms of shadow prices. This cost benefit profile was used to calculate net benefits. The net benefits were discounted to present values using a composite social discount rate equal to 5.97 percent. The same decision making criteria used in the private CBA were used in the social CBA and a sensitivity analysis was completed by varying the social discount rate. In terms of the private CEA, the costs were identified and valued in terms of market prices. All costs were brought to present values using the private discount rate of 6.42 percent. In terms of the social CEA, the costs were identified and valued in terms of shadow prices. All costs were brought to present values using the social discount rate of 5.97 percent. The cost-effectiveness (CE) ratios calculated have identical denominators since the annual output for both technologies are identical - both CPV and PV systems deliver 30 300 kWh per annum. This output is based on the demand of the given case study. The private CBA showed unfavourable results. The private CBA has a NPV of R2 046 629.01, the IRR is undefined (this is due to no sign change being present in the cost benefit profile), and has a BCR of 0.365. However, the social CBA yielded positive results, with a NPV of R125 616.64, an IRR of 8 percent (which exceeds the social discount rate of 5.97 percent), and a BCR of 1.045. The CEA showed that the CPV is more cost-effective than the traditional PV both in terms of private and social costs. The private CE ratio of CPV is R4.23/kWh compared to PV's CE ratio of R4.39/kWh. Similarly, the social CE ratio of CPV is R3.51/kWh compared to PV's CE ratio of R3.69/kWh. CPV rollout appears to be socially efficient on a small scale according to the social CBA. Consequently, the CPV project is not seen as desirable in terms of the private CBA as the benefit (income received per kWh) in the private analysis is too small to outweigh the costs of implementing and running a CPV plant in Tyefu. On the other hand, a redeeming factor is that CPV may be feasible privately, for large scale applications. A major reason for the CPV project not being appealing to private investors is that the maximum bidding price of R2.85/kWh (as at August 2011) is not high enough for private investors to undertake the CPV project. The sensitivity analysis of the bidding price showed that the bidding price of R2.85/kWh needs to be increased in the range of 250 percent (R7.13/kWh) and 300 percent (R8.55/kWh) for a great enough incentive to exist for private investors. It is thus recommended that policymakers take this into consideration when formulating policy. In terms of the social CBA, it is recommended that government undertake CPV projects of this kind, as it will be a socially desirable allocation of resources. If government were to pursue these types of projects, it is recommended that CPV be implemented as it is more cost effective than PV.

- Description: South Africa relies heavily on fossil fuels, particularly coal, to generate electricity and it is a well known fact that the use of fossil fuels contributes to climate change, as it produces greenhouse gases (GHGs). In fact, internationally South Africa is the 17th highest emitter of GHGs (Congressional Research Service (CRS), 2008). Coupled with the environmental consequences of fossil fuel use, South Africa has a further responsibility of addressing the inherited backlog of electricity provision to the rural, and previously disadvantaged communities. In an attempt to address these two problems, the government issued the White Paper on Renewable Energy. In this paper, renewable energy alternatives are proposed to replace a portion of traditional electricity generating methods. Concentrator photovoltaic (CPV) energy generation is one such renewable option available to government. CPV uses optic elements (such as lenses) to concentrate sunlight onto solar cells. Owing to the light being concentrated, the cells in CPV use less semiconductor material, which makes them more efficient in comparison to conventional photovoltaic (PV) cells. CPV is a technology that operates well in regions with high solar radiation. As such, South Africa is particularly well suited for this technology, with average solar radiation levels ranging from 4.5 to 6.5 05 ℎ/. CPV is also well suited for off-grid application, which addresses electricity demand in remote rural areas. This study is an economic project analysis of the installation, operation, maintenance, and decommissioning of CPV technology in a rural area in the Eastern Cape, South Africa. The study area chosen for this purpose is the Tyefu settlement in the Eastern Cape. Tyefu was deemed ideal for this type of analysis due to four characteristics. Firstly, Tyefu is a remote rural settlement at the end of the national grid. Secondly, the community is very poor and previously disadvantaged. Thirdly, many households are without Eskom generated electricity. Lastly, the study area is located in an area with ideal irradiance levels for CPV. Two methods of economic project analysis are applied to this case study, namely a costbenefit analysis (CBA) and a cost-effectiveness analysis (CEA). Additionally, two types of CBA are performed, namely a private CBA and a social CBA. The private CBA evaluates the Tyefu electrification project from a private investor's perspective and the social CBA evaluates the project from society's point of view. The CEAs carried out compare the costeffectiveness of the traditional PV technology to that of CPV in terms of private and social costs. The private costs and benefits of the CPV project were identified and valued in terms of market prices. Then, this cost benefit profile was used to calculate net benefits which in turn were discounted to present values using a private discount rate of 6.42 percent. Three decision making criteria were generated, namely the net present value (NPV), the internal rate of return (IRR) and the benefit cost ratio (BCR). Sensitivity analysis was carried out by varying the private discount rate and the bidding price. The social costs and benefits of the CPV project were identified and valued in terms of shadow prices. This cost benefit profile was used to calculate net benefits. The net benefits were discounted to present values using a composite social discount rate equal to 5.97 percent. The same decision making criteria used in the private CBA were used in the social CBA and a sensitivity analysis was completed by varying the social discount rate. In terms of the private CEA, the costs were identified and valued in terms of market prices. All costs were brought to present values using the private discount rate of 6.42 percent. In terms of the social CEA, the costs were identified and valued in terms of shadow prices. All costs were brought to present values using the social discount rate of 5.97 percent. The cost-effectiveness (CE) ratios calculated have identical denominators since the annual output for both technologies are identical - both CPV and PV systems deliver 30 300 kWh per annum. This output is based on the demand of the given case study. The private CBA showed unfavourable results.

However, the social CBA yielded positive results, with a NPV of R125 616.64, an IRR of 8 percent (which exceeds the social discount rate of 5.97 percent), and a BCR of 1.045. The CEA showed that the CPV is more cost-effective than the traditional PV both in terms of private and social costs. The private CE ratio of CPV is R4.23/kWh compared to PV's CE ratio of R4.39/kWh. Similarly, the social CE ratio of CPV is R3.51/kWh compared to PV's CE ratio of R3.69/kWh. CPV rollout appears to be socially efficient on a small scale according to the social CBA.

- Description: The Society for Conservation Biology held their 21st annual conference in Port Elizabeth during July 2007. This was the first SCB conference hosted on the African continent. Over 1500 conservation professionals and students from throughout the world were brought together by the SCB annual meeting. The local organizing committee was interested in the economic impacts associated with the conference and approached the NMMU Economics Department to conduct an economic impact assessment of the conference. The Economics Department invited the researcher to undertake this study towards obtaining an MCom degree in Economics. The economic impact of conferences stems from two sources, namely: expenditure by delegates (the demand-side) and the expenditure by conference organizers (the supply-side). The study focused on the economic impacts of the conference for the Eastern Cape. The conference expenditure produced an increase in demand in the Eastern Cape. Only new expenditure originating from outside the Eastern Cape were considered. An increase in the demand for one industry’s output will create additional demand for the outputs of its supplying industries, because industries are connected through forward and backward linkages. These inter-industry linkages produce a multiplier effect. The initial direct conference expenditure created secondary impacts. The latter were indirect and induced expenditures. In addition to secondary impacts, the SCB conference produced spill-over impacts. The spill-over impacts of the conference were noted (but not quantified). The expenditure by delegates was determined by means of a delegate expenditure questionnaire conducted during the conference. The expenditure by the conference organizers was determined in consultation with the organizers, using their financial statements. The multiplier impacts were estimated by means of an input-output (IO) analysis, using a Social Accounting Matrix (SAM) of the Eastern Cape as the underlying database. These multipliers (Type 1 and 2 multipliers) were estimated using open and closed multiplier models. It was deduced that the 2007 SCB conference created a significant and positive net economic impact in the Eastern Cape. The total direct cash injection of the conference was R12.141 million. Using a Type 1 multiplier this direct stimulus is estimated to have caused an extra R16.502 million increase in gross output. Using a Type 2 multiplier this direct stimulus was estimated to have caused a R19.884 million increase in gross output. The total cash injection of the conference contributed R6.093 million to GVA in terms of a Type 1 multiplier and a R7.344 million increase in GVA in terms of a Type 2 multiplier. Household incomes in the Eastern Cape were increased by R3.384 million. These results confirm that the hosting of major events and conferences is indeed a tool for promoting regional economic development.

- Description: Renewable energy technology has received much attention over recent years. The depletion of known fossil fuel reserves and the volatility of international fuel prices require that society looks beyond the current coal-dominated electricity generation methods. Wind energy is an internationally well-established technology with large markets in major countries around the world, such as the USA and Germany. South Africa has the potential to generate large amounts of electricity from the wind because of the strength of the country’s wind resource. The long coast line and open areas are ideal for the exploitation of wind energy. A wind farm project has been proposed for development near the town of Jeffrey’s Bay, in the Eastern Cape. The proposed project involves the construction and installation of a 15MW wind farm, consisting of 6-10 turbines standing 120m tall, over an area of 20ha.There are indirect costs and benefits (externalities) associated with a wind farm project and it is important that projects such as these are evaluated from a social standpoint. The aim of this study was to determine the compensation required by residents for siting a wind farm in their area. This compensation was then used as a component of an overall evaluation of the project.

- Description: South African manufacturers, including those who produce electrical and telecommunication cables, are required by the National Waste Management Strategy (NWMS) (drawn up by the Department of Environmental Affairs and Tourism (DEAT)), to carry out waste management in a coordinated and controlled manner. It is also becoming more difficult for South African companies, who produce for export markets, to conduct business internationally if they do not have some form of environmental management system in place. While there will always be scrap generated in any manufacturing environment, the aim is, first and foremost, to reduce this to acceptable levels and, secondly, to dispose of all scrap produced in a socially responsible manner. This study focuses attention on waste management, in the form of recycling, in the cable manufacturing industry. The purpose of this study is twofold: first, to examine the economic case, by means of a cost-benefit analysis, for the establishment and operation of a telecommunication cable waste recycling plant for the purpose of recycling copper conductor; second, to examine the economic feasibility, by means of a cost-benefit analysis, of extending the existing facility in order to accommodate the recycling of the plastic fraction contained in the cable waste. A specific cost-benefit stream was generated over a project period of 20 years for both CBAs. In both CBAs costs and benefits were categorised as being either primary or secondary. The primary costs and benefits for both CBAs were all financial in nature and were valued using market prices. The secondary costs of establishing and operating a cable waste recycling plant for recycling the copper conductor included effluent costs and noise pollution costs. The secondary benefits, on the other hand, included the creation of downstream industries. The secondary costs of extending an existing cable waste recycling plant, so as to accommodate the recycling of the plastic component of cable waste, included costs related to the generation of greenhouse gases and asthma. The secondary benefits, conversely, included the increase in house prices due to the reduction of landfilling of the plastic component of cable waste. The determination of increased house prices due to landfill avoidance was carried out using the hedonic pricing method (HPM). The hypothesis was that house values would increase the further removed they were from the landfill site. Applying regression analysis to the derived hedonic pricing (HP) function showed that there is a definite correlation between the two. Properties positioned two kilometres from a landfill site in New Brighton Port Elizabeth, Eastern Cape, were found to have higher values than those positioned adjacent to the site. From the cost-benefit streams, net benefits were calculated for each CBA and discounted to present values in order to provide a standard of comparison. The social discount rate used in this study to calculate the present values reflected a combination of the social opportunity costs of capital and the social time preference rate. The rate used was calculated as the average annual rate between 2000 and 2005 and amounted to 6.72 percent. It was derived from a combination of the opportunity costs of government borrowings, household consumption borrowings and return on savings.

- Description: In 2008, the global economy went into recession. Millions of jobs were lost, confidence in the financial markets fell and billions of dollars were lost by investors. Prior to the onset of the recession, the major economies of the world (USA, and Western Europe) had experienced a period of economic boom and expansion. Austrian Business Cycle Theory proposes that the roots of the current financial crisis and recessions in general, are found the actions of central banks through credit expansion and manipulation of interest rates. Central banks manipulate interest rates causing them to fall below the natural level, leading to credit expansion and malinvestments. Austrian Business Cycle Theory is based in capital theory. Capital theory incorporates the elements of time and money and allows the setting of a microeconomic foundation. The theory recognises that investment is not an aggregate (as do Keynesians and Monetarists). Opposition to empirical testing by Austrian economists has meant that few statistical analyses of Austrian Business Cycle Theory have been carried out. The apprehension toward empirical testing of Austrian Business Cycle Theory stems from some Austrian economists who argue that human behaviour cannot be captured in statistical terms. Recently, some Austrian economists have begun to do empirical research Austrian Business Cycle Theory and the thesis adds to that growing field. The thesis tests empirically for ABCT in South Africa by using Vector Error Correction Model and Granger causality techniques and the results are as follows: The Vector Error Correction Model shows that any disequilibrium adjustment in the structural equations influences correction mostly through changes in Manufacturing. The disequilibrium adjustment process for Investment is also found to have statistical significance. The results propose that Investment in South Africa is not inert. The Granger causality tests show that credit expansion causes interest rates to be artificially lowered leading to mal-investments. The main policy recommendation is that business cycles can be prevented by not manipulating interest rates and by not increasing credit availability.
