- Description: In the past 16 years, the use of League Tables and Rankings (LTRs) as a tool to rank or measure the performance of Higher Education Institutions (HEIs) has grown in popularity. As a global practice, LTR outcomes are influencing how policies are developed and implemented within the Higher Education (HE) sector. Studies indicate that based on individual information requirements, HE stakeholders are using LTRs to compare HEIs with each other and make informed comparisons and decisions. University directors use LTRs as a basis for institutional strategic planning, reputation building and policy making, while students use LTRs to compare HEIs and make university of choice decisions. Further studies confirm that governments use LTRs for national higher education policy making, university funding, foreign partnerships and resource allocation. Globally and at a national level, the higher education sector has witnessed policy and structural changes, many of which are due to the increase in the use of international rankings and league tables. Despite the opportunities presented by participating in the production of and using LTRs, the ranking practice is contentious. Amongst the issues disputed by the HE stakeholders are the methodologies and criteria used in the production and publication of LTRs. Higher education experts argue that LTRs tend to favour institutional research output and ignore the teaching and learning function of HEIs. As a result, the ranking criteria differ across the higher education ranking institutions and their publication outcomes, which causes skepticism across the HE sector. Research indicates that these ranking criteria are often discussed from the standpoint of governments, the higher education management and the ranking institutions producing these LTR publications. The opinions of the students on the suitable ranking criteria used by ranking institutions lack. This study aims to address that gap. This study investigates the applicable criteria for ranking HEIs in South Africa, from the perspective of students. Building on the existing ranking criteria for three global and popular ranking institutions namely, Academic Ranking of World Universities (ARWU), Times Higher Education World University Ranking (THEWUR) and Quacquarelli Symonds World University Ranking (QSWUR), the study poses the question; “What framework can be used to rank HEIs in South Africa, from a student’s perspective?” The study argues that although some HEIs in South Africa have in the past and most recently appeared in the global LTRs, the current choice of ranking criteria fails to consider the perspectives of the students, who are major consumers of LTRs and important stakeholders in the HE sector. A positivistic research method was used, based on a review of literature on the current ranking criteria for the selected global ranking institutions. An empirical study was conducted amongst students in a South African Comprehensive University. An online survey was distributed through convenient and snowball sampling, where the students were requested to participate in the survey and share the questionnaire link with others. Eight hundred and eighty six (886) responses were received and used for the data analyses of this study.

- Description: The internationalisation of higher education has become an inevitable focus in the modern day higher education sector. This focus is due to the interconnectedness of society, which is driven by globalisation. The ever-changing landscape of the current global higher education sector has further placed emphasis on self-funding and the corporatisation of higher education institutions (HEIs). This has created competitiveness in the sector for local and international students, which has led to institutions globally and in South Africa, being tasked with the responsibility of being agents of internationalisation. The concept of higher education internationalisation involves internationalisation of the curriculum, cross-continental partnerships, the increase in mobility of staff and students, educational programmes, innovative ways of delivery as well as the need to be globally competitive. Students themselves view international study important as it provides them with a global outlook and international experience. The increased competitiveness in the higher education sector and the need for HEIs to become more autonomous and self-funded, has amplified the need to recruit international students who generate additional income. Furthermore, the strategy to recruit international students has evolved and transformed into a customer-driven strategy to meet the needs of the knowledge economy. To recruit international students, HEIs must invest in marketing and recruitment strategies, which build brand awareness and attract a diverse student body. This study investigates the development of a strategic university of choice model that can assist South African universities in the recruitment of international students by focusing on the factors, which influence a student’s university of choice. This was realised firstly by conducting a pilot study investigating the factors which influence the university of choice of students studying in South Africa. Secondly, the findings of the pilot study, combined with appropriate literature studies were used to develop a questionnaire to aid in determining the factors which influence the university of choice of international students studying in South Africa. Lastly, the findings of the questionnaire were used to draw conclusions and develop a proposed strategic model to promote the university of choice decisions among international students studying in South Africa. This thesis is an exploratory, mono-method quantitative study, which consists of literature reviews and surveys in a cross-sectional timeframe. The literature reviews were conducted on secondary sources to identify the factors that influence university of choice, as well as the marketing and recruitment trends within higher education. The empirical study consisted of a Pilot Study Survey and a Main Study Survey. The measuring instrument was compiled from existing surveys and literature studies. The findings of the Main Study Survey identified the following main factors of influence on university of choice: academic programme, academic quality, visa requirements, country/city attractiveness, English language, financial, International Office, student life, safety and security, university location and university reputation as main factors of influence. Within these main factors, various sub-factors were identified. The findings further illustrated that certain factors were more consultative in nature and provided information, which aided in the decision-making process. These factors are: motives to study/choose a programme, country attributes and influences/recruitment methods. Additionally, a third set of factors deemed to subconsciously influence the student’s decision-making process were identified as background of the student, study level and student type. The study contributes theoretically to Stakeholder Theory and Means-End Theory. Prospective students, who are higher education stakeholders, have diverse information needs and expectations, which will be met through the use of the proposed strategic model. Furthermore, the prospective students’ input will aid in the development of focused, targeted and cost-effective marketing and recruitment strategies, which will in turn meet the needs of universities to recruit a diverse student body.

- Description: This research makes a contribution to the body of knowledge on unconventional oil and gas extraction (UOG) in the Karoo, South Africa. It provides a detailed analysis grounded in future studies theory and practice, which supports the argument that UOG extraction in the Karoo may potentially be conducted under the careful guidance of sustainable development and climate change principles. It is informed by the researcher’s perceptive and experience as a manufacturer of oil and gas products and his understanding of the fossil fuel sector and the role it currently plays in the South African economy. It is further informed by the researcher s understanding of the sector’s damaging climatic and environmental impacts. The practice of offering new insights through the application of futures studies is central to the process, and specific methodologies and tools have been used to develop four scenarios for the UOG extraction in South Africa. This framework allows for easy assessment for policy-making. Never has scenario art, which has been expertly created during the workshops, been used in South Africa to generate memorable and lasting scenarios memorable and lasting scenarios. This research seeks to provide insight regarding for South Africa’s quest for energy security in ways that support the climate change agenda. Given the shale controversies, most environmentalists prefer lower-carbon and reduced fossil fuel usage. However, South Africa can ill-afford this luxury at this stage and while the research considers the option of no-shale exploration and a direct path to renewable energy solutions (the ‘No-Shale, what now?’ scenario) it also. proposes other options for consideration. An integrated vision is put forth as the preferred scenario in which shale is the conduit to a sustainable energy future and which implements wide-scale climate change mitigation and adaptation strategies.

- Description: In general, facilities are constructed and equipment is procured to meet the functional and utilitarian needs of an organisation. Daily use and abuse can affect the functional value of these resources and without regular maintenance there will be no real benefits derived from non-functional facilities and equipment. Conducting effective and systematic maintenance is one of the fundamentals which underpins the success of an organisation and if ignored, could be costly to rectify. Costs escalate in the form of deferred maintenance budgets, which have a knock-on effect of growing year on year. This highlights the context of universities’ operations managers who may lack proper management and planning tools to either use or apply effective maintenance budget forecasting models. Having properly maintained facilities is imperative since deferring maintenance will adversely affect employees’ occupational health and safety, impact on the cost of operations and the morale of those who use the dysfunctional facility. The most daunting task of facility managers, is to ensure that all facilities remain fully and consistently operational. This entails providing an efficient maintenance service, which prevents system failures and extends the useful life of both the production plant and facilities to be managed. The need to protect costly and varied assets against the depredation of time and keeping it maintained for current use takes significant and continuous investment of time, money and human resources. Due to the cost of maintenance, in most instances maintenance is scheduled to be done when actual facilities are not in operation, usually at the end of a financial or calendar year. The intangible nature of the maintenance function and the inability to completely justify maintenance funding budgets, lead to the required funding not being obtained from a budgetary request. This inevitably has the undesirable consequences of huge capital backlogs in the form of deferred maintenance. This study moves the research problem and argument away from strictly for-profit business (manufacturing) entities to interrogate service-oriented parastatal and hybrid funded University facilities’ operations and maintenance management. Universities are multidisciplinary structures that encompass a broad spectrum of services required to ensure the effective and efficient academic, administrative, experimental and research focused operation of the Institution. Universities are not excluded from ensuring that sufficient funding is obtained for the effective maintenance of their facilities. This research aims to derive a tool to simplify the selection of a suitable maintenance budget forecasting model and to recommend a maintenance budgeting model for use within universities of selected countries of Southern Africa. The literature survey revealed that there are numerous maintenance budgeting forecasting models already in existence in many different shapes and sizes. For this reason, a content analysis was conducted of 31 maintenance budget forecasting models in order to be able to differentiate between the numerous models. This empirical study conducted among universities of selected countries of Southern Africa outlined the current maintenance funding models being used, inclusive of the amount of funding obtained and the existence/lack of deferred maintenance of various Institutions. After analysing the secondary data (in the form of a content analysis) and the empirical data collected, a model was chosen to recommend for implementation in future institutional planning and business practice. Based on the content analysis and empirical review, the recommended maintenance budget selection tool was derived focusing on sharpening the decision making process of selecting a suitable, fit for purpose, maintenance funding model. After this phase of the research, a follow up phase was conducted amongst high level executive decision makers, to qualitatively verify or support the findings from the first phase of the data collection. This research therefore concludes with recommendations to the respondent universities of selected countries of Southern Africa, about a suitable maintenance budgeting forecasting model. It also recommends a selection tool to use if alternative maintenance budget funding models need to be selected. This multidisciplinary study contributes to the literature by contextualising the maintenance budget forecasting for operational universities and in future adding significant value to the proactive management of deferred maintenance in practice.

- Description: Financial analysis is important when assessing a business’ financial as well as economic performance, and ratios are among the best known and most widely - used tools for financial analysis. Ratios act as a benchmarking and trend analysis tool by disclosing relationships as well as bases of comparison that reveal conditions and trends that cannot be detected by the individual components of the ratio. In addition, there is a need to measure sustainability performance as sustainability aims to radically transform how businesses understand and create value. Measuring sustainability performance can determine whether a business is moving in the right direction. This study developed a proposed set of sustainability ratios that could be used to determine the efficient and effective sustainability performance of public listed companies in South Africa. The study used a mixed methods research approach in three phases consisting of ten steps. In Phase 1 (Step 1), a secondary research in the form of a literature review was conducted. The critically evaluated secondary literature sources were used to create a theoretical framework of sustainability ratios and a ‘schedule for content analyses. In Phase 2 (Steps 2, 3, 4, 5), a quantitative content analysis of sustainability reports of FTSE/JSE Responsible Investment Top 30 Index companies was performed to obtain the variables that were used to calculate the sustainability ratios in the theoretical framework. It also identified additional sustainability ratios that were used by companies in practice, but that were not included in the theoretical framework of sustainability ratios. The sustainability ratios from the theoretical framework were calculated using the variables collected from the sustainability reports. Thereafter, descriptive statistical techniques were used to analyse the results. Lastly, in Phase 3 (Steps 6, 7, 8, 9), qualitative criteria were used to test the variables for the sustainability ratios that could not be calculated and to select the ratios from those calculated, reported and tested to be included in the proposed set of sustainability ratios. The purpose of Phase 3 was to test the usability, relevance, measurability, understandability and comparability of the sustainability ratios proposed in the theoretical framework as well as the sustainability ratios that were applied in the content of sustainability reports in South Africa. Step 10 represented the outcome of the study, a set of sustainability ratios was proposed. A set of 101 sustainability ratios were proposed. The proposed set of sustainability ratios linked the different sustainability issues to financial results by classifying them into four main categories, namely, (i) sustainable operational efficiency and effectiveness ratios (SOEE), (ii) sustainable risk - minimisation ratios (SRM), (iii) sustainable reputation – brand value ratios (SRBV) and (iv) sustainable innovation ratios (SI). These sustainability ratios could be used to assess the efficiency and effectiveness of a business’ sustainability strategies, its risk minimisation strategies, innovative capacities and reputation as well as brand value enhancing strategies. As the concern for business sustainability increases, the proposed sustainability ratios might satisfy the concerns of customers and stakeholders. These proposed ratios could also be refined in the future.

- Description: The purpose of this Qualitative research was to determine the metrics required to define the Long-Term Sustainability of a Multinational Enterprise (MNE). The study investigated and analysed how the individual subsidiaries of a listed organisation interpreted LTS and what measurements (metrics) were the most important in supporting this long-term approach. The research analysed questionnaires administered to managers from different disciplines within the organisation. This process sought to accumulate a set of responses and through the statistical analysis of these responses, in particular, extensive qualitative research was used to find a common thread of relevant metrics, which can be used presently and in the future to determine LTS. The researcher reviewed models and the literature to establish a set of questions for the construction of individual questionnaires. This was based on current theory combined with institutional knowledge and experience. The questionnaires were designed to provoke responses from management of their view of the important contributors to LTS. The individual questionnaires (Annexures I to VIII) comprised a series of focused questions and multiple-choice answers based on either 5 or 10-point Likert scales and a few open-ended questions. The main respondents were VPs, MDs, OMs, Human Resource Managers, Financial Managers, and Sales and Marketing Managers of the subsidiaries within the MNE. These “At the heart of an excellent manufacturing business rests the efficiency of its operations, the commitment of the people who manufacture the products, the level of motivation of the workforce, the passion of its salesforce and the innovation shown by its engineers” respondents were all best suited to answer questions at the required level of expertise, when taking into consideration the LTS of the organisation. The data obtained from the research was used to devise suggested scorecards that may be used as guidelines for current and future initiatives when considering LTS. Qualitative research methods were used in this research as they seek understanding of “how things work in particular contexts”. This allows for the building of new theory and the conceptual advancements of knowledge, starting with very general concepts which, as the research progresses, change their definition (Brannen, 2016). In qualitative research, researchers use themselves as the instrument, attending to their own cultural assumptions as well as to the data. to achieve imaginative insights into the respondents’ social worlds. (McCracken, 1988). Concepts and categories are relevant to qualitative research. as quantitative research is an exercise in analytical induction.

The study investigated and analysed how the individual subsidiaries of a listed organisation interpreted LTS and what measurements (metrics) were the most important in supporting this long-term approach. The research analysed questionnaires administered to managers from different disciplines within the organisation. This process sought to accumulate a set of responses and through the statistical analysis of these responses, in particular, extensive qualitative research was used to find a common thread of relevant metrics, which can be used presently and in the future to determine LTS. The researcher reviewed models and the literature to establish a set of questions for the construction of individual questionnaires. This was based on current theory combined with institutional knowledge and experience. The questionnaires were designed to provoke responses from management of their view of the important contributors to LTS. The individual questionnaires (Annexures I to VIII) comprised a series of focused questions and multiple-choice answers based on either 5 or 10-point Likert scales and a few open-ended questions. The main respondents were VPs, MDs, OMs, Human Resource Managers, Financial Managers, and Sales and Marketing Managers of the subsidiaries within the MNE. These “At the heart of an excellent manufacturing business rests the efficiency of its operations, the commitment of the people who manufacture the products, the level of motivation of the workforce, the passion of its salesforce and the innovation shown by its engineers” respondents were all best suited to answer questions at the required level of expertise, when taking into consideration the LTS of the organisation. The data obtained from the research was used to devise suggested scorecards that may be used as guidelines for current and future initiatives when considering LTS. Qualitative research methods were used in this research as they seek understanding of “how things work in particular contexts”. This allows for the building of new theory and the conceptual advancements of knowledge, starting with very general concepts which, as the research progresses, change their definition (Brannen, 2016). In qualitative research, researchers use themselves as the instrument, attending to their own cultural assumptions as well as to the data. to achieve imaginative insights into the respondents’ social worlds. (McCracken, 1988). Concepts and categories are relevant to qualitative research. as quantitative research is an exercise in analytical induction.

- Description: It has become standard practice at Higher Education Institutions (HEIs) for their Internet management and relevant Information and Communication Technology (ICT) resources, specifically Internet resources, to be continuously investigated by HEI Management as well as by their users. The reason is that the Internet has become the foundation on which most ICT and business resources function and therefore is labelled as a distinctive competency for the HEI. HEIs, however, have limited ICT Internet resources and are expected to use these resources optimally, to ensure efficient and effective Internet connectivity on all campuses and to all users and systems. The management of Internet resources at South African Higher Education Institutions (SA HEIs) are the focus of this thesis. The primary purpose therefore, is to provide a proposed adaptive Internet Management Model for HEIs which will assist them to achieve prime value from their Internet management resources. This was realised by firstly; identifying the current Internet Management Business Models of the SA HEI landscape; secondly, determining what the Internet users of the Nelson Mandela University, a South African Higher Education Institute situated in the Eastern and Western Cape area in South Africa, were using the Internet for; thirdly, comparing these findings to the actual Nelson Mandela University Firewall data and lastly, using the combined findings to draw conclusions and create a proposed adaptive Internet Management Model for HEIs. This can assist the HEI ICT Management team to realign the Internet resources to match the current business and customer requirements. This thesis is an exploratory, mixed method study which consists of literature studies, surveys and cross sectional studies. The literature studies were conducted on secondary sources to identify the national and international governance structures that influence Internet management. The empirical study which consisted of two surveys was compiled from existing surveys as well as from literature studies and was completed by its respective respondent groups. The first survey was used to gain insight into what was considered the standard Internet Management Business Model at HEIs in South Africa. The second survey was used to gain insight how the Internet was being used at Nelson Mandela University by staff and students. Lastly, an extract of the Nelson Mandela University Firewall data were gathered and used to confirm or deny results from the previous survey. The findings of the first survey, HEI Internet Management Survey (HEIIMS), confirmed that the Internet and its relevant resources are extremely important to all HEIs. The HEIs Internet Management Business Models are to a large extent aligned with the National Research an Education Networks (NRENs) business models with some adjustments. The HEIs indicated that they cater for a large Internet community but do not differentiate between them. The findings do, however, specify that some differentiation does take place. The HEI Internet is provided to the Internet community at no cost and is funded by Council funds. The requirements of staff and students are mostly similar with some priority differences to key content needs. The Internet resources of the HEIs are very much aligned to support the physical infrastructure of the Internet. HEIs consider the NRENs to be key partners and suppliers with additional local suppliers used as secondary support. The second survey, Nelson Mandela University Internet Usage Survey (NMUIUS), indicated that there was a wide gap between how the Internet was used by the staff and students. The findings indicated that staff tend to be more aware of the policies and surrounding practices while students appeared somewhat unaware. The staff and students have different needs for the Internet and these needs also change slightly according to the time of day and day of the week. Regarding content access (including Firewall data), some of the users said Internet practices were true whilst others were false. The majority of those giving a false opinion said that said Internet practices were focused on activities linked to cyberloafing content. In addition, they stated that these activities were undersold, meaning that they said that they access the Internet content rarely while the Firewall data indicated that it was frequently being accessed and by many users. It was clear that the staff received a pleasant Nelson Mandela University Internet experience while the students received a slightly degraded Internet experience. The study concluded with the development of a proposed adaptive Internet Management Model for HEIs and recommendations and considerations on how to improve the current Nelson Mandela University Internet management strategy. This thesis makes a contribution towards the body of knowledge by identifying and discussing current national and international Internet Governance (IG) practices. It continues by identifying the current SA NRENs and their business models which overflow into the HEI landscape. This is followed by an investigation into the various HEI Internet Management Business Models, current usage of the Nelson Mandela University Internet and patterns of use and Nelson Mandela University Firewall data. The thesis will therefore assist readers to understand the effective and efficient management of their Internet usage requirements and the provision of Internet resources. This in turn, will confirm that the availability of the Internet for its users and systems becomes a productive, reliable and pleasant experience.

- Description: Over the years, people have planned and carried out their activities depending on their indigenous knowledge base. In agriculture, documented importance of indigenous knowledge has been noted in different ways such as in crop health management, soil nutrient management, and food processing and food preservation. Indigenous smallholder farmers across the world have developed techniques that reflect their intimate knowledge of their local environments and ecosystems to improve their agricultural yields and minimise postharvest losses. However, such indigenous knowledge techniques are rarely documented or enhanced to boost agricultural practice and ensure food security. The present study has identified potato farming in Cameroon as a potential contributor to the socio-economic development of farmers, their communities and their country. The potato farming industry largely consists of smallholder farmers, predominantly women, producing primarily of immediate consumption. Historically, these farmers have been sustaining their farms through indigenous knowledge and practices that are not being exploited to the fullest beneficial opportunities for these farmers. It has often been suggested that Western highly mechanised approaches should be implemented to commercialise these farms in order to access these benefits. These approaches of mechanisation require large capital outlays, which these smallholder farmers cannot afford, hence the approach taken by the present study to capitalise on the indigenous knowledge and practices of these farmers. The present study argued that working with the existing indigenous knowledge and practices of these farmers, a level of commercialisation, with the resulting job creation and economic benefits, could be achieved. This study has succeeded in identifying the causes of postharvest potato losses on the smallholding farms, the obstacles in reducing these losses and the techniques to reduce these losses. The study provides important recommendations to improve smallholder potato farming in Cameroon. By implementing the findings of this study, the Cameroon government, prospective potato farmers, entrepreneurs, traditional authorities and NGOs could make a significant contribution to the improvement of socio-economic conditions and the reduction of poverty levels in these farming communities.

- Description: At present, frontline equipment employed at B&E International, and operating within the quarrying sector is typically replaced as soon as the operating expenses are deemed to be excessive. From a capital budgeting perspective, the trigger for signalling the replacement of equipment occurs when prescribed operating cost performance metrics are violated. In some instances, a further consideration for motivating the replacement of equipment is when the perception arises that the nonavailability of the equipment employed, results in financial losses being incurred by a company. It can therefore be argued that the current equipment replacement timing methodological approach adopted at B&E International is suboptimal in nature. The situation is further aggravated by the fact that in many instances, escalation of commitment manifests itself whereby unnecessary capital is repeatedly invested in order to extend the life of an asset resulting in a situation occurring whereby the required level of investment return is not achieved. In the event of these situations arising, the decision to replace an asset is prolonged as a result of the suboptimal investment decisions being made. The primary focus of this study is to provide a methodological equipment replacement framework that is based upon sound capital budgeting fundamentals. A comprehensive literature review of capital budgeting approaches that specifically focus on the optimal replacement timing of frontline quarrying equipment, did not yield any relevant studies that have been undertaken in this regard. This study did however investigate contemporary equipment replacement approaches based upon a capital budgeting paradigm and highlighted their respective limitations. Convincing evidence obtained, indicated that the most widely accepted method of identifying the optimal replacement timing of equipment occurs when the economic life of the asset is attained. This in itself would therefore infer that a cost minimisation approach is the most pervasive methodological approach adopted in order to identify the optimal replacement timing of equipment. When considering capital investment based decisions, it was found that the discounted cash flow based methodologies are the most widely used and accepted approach applied in the mining industry. Notwithstanding this, one major caveat manifests itself in that when considering the optimal replacement timing of front line equipment within the quarrying industry, the inclusion of uncertainty, flexibility and the associated financial risks was not evident. In order to model these effects, a probabilistic Net Present Value (NPV) approach was adopted and the required Discounted Cash Flow (DCF) models were constructed. Given the uncertainty of the expected cumulative R&M profiles for the asset classes constituting this study, an extensive statistical analysis was carried out in order to establish the required predictive Repair and Maintenance (R&M) models required for the DCF analysis by means of regression analysis. Further regression analyses were conducted in order to model the overall availability and utilisation metrics for the respective asset classes included in this study. The consequence of incurring downtime was investigated and the resultant DCF analysis yielded a significant impact on the Free Cash Flow (FCF) generated by the respective assets. The magnitude of the incurred consequential financial losses incurred as a result of the respective downtime was found to be significant when considering frontline equipment. In order to model the effect of, and the extent to which, the respective independent variables influence the static NPV outcome, a sensitivity analysis was performed. From this, the influence of the independent variables constituting the NPV model employed in this study, were observed. A Real Options Analysis (ROA) approach was initially employed in order to model the effects of FCF uncertainty and the results of carrying out this analysis indicated a minimal influence on the static NPV model referred to earlier. It was therefore concluded that from an equipment replacement timing perspective, the ROA approach did not provide a robust and accurate representation of the probabilistic NPV outcomes anticipated. In order to address these perceived shortcomings, an Monte Carlo Simulation (MCS) model was constructed and the requisite probability distribution functions representing the most influential independent variables determined from the sensitivity analysis were identified and subsequently analysed. The results of the MCS analysis yielded the expected NPV outcomes that were found to be far more conservative compared to the static NPV outcomes referred to previously. Furthermore, the concluding findings of this study indicate that in order to estimate the optimal time to dispose of an asset, a static NPV analysis must first be modelled and thereafter a probabilistic NPV analysis. The respective uncertainty aspects over the lifespan of the assets should be identified to be incorporated into the MCS model. This methodological approach therefore opposes the use of a strictly deterministic based approach and rather predicates the use of a probabilistic NPV based framework. This study further concluded that traditional DCF approaches fail to consider management flexibility in terms of adapting to uncertainty and to also reduce the possibility of “escalation of commitment” occurring as a result of sub-optimal equipment replacement timing decisions by management. The use and acceptance of the traditional DCF approaches are acknowledged, but in order to develop an equipment replacement methodological approach that considers uncertainty and risk on the one hand and also allows for the incorporation of real data over the assets lifetime on the other, the use of an MCS probabilistic NPV based model was found to be the optimal approach to be adopted. The result of updating the static NPV model with updated data as soon as it is obtained enables one to generate accurate probabilistic distribution functions required for the subsequent MCS analysis. By adopting this approach the study has concluded that one can obtain realistic and accurate NPV forecasts from the anticipated FCF estimates. The principal conclusion obtained from this study is that the optimal time in which to replace front line assets employed at B&E International is when the probabilistic net earnings profile, viz., NPV of the equipment is maximized.

- Description: Recent years have seen the decline of entrepreneurial activity in South Africa. This is especially concerning in that, officially, 27.7% of South Africans are unemployed. The unofficial unemployment figures are closer to 50%. The South African economy is battling to recover from the world economic crisis of 2009/10, putting pressure on government to alleviate growing unemployment and curtail social unrest. Furthermore, a South African economy which thrives on entrepreneurial activity will become more competitive from a global perspective. The purpose of this study is to contribute to the promotion and development of entrepreneurship in South Africa, in an effort to combat the problems listed above. In order to achieve this purpose, the objective was to develop and test a model which could be used in the development of entrepreneurs. The rationale is that, if the factors which affect entrepreneurship could be identified and tested, then recommendations could be made which could promote the development of entrepreneurs in South Africa. The approach was as follows: Perform a literature review which would cover both global and local (South African) approaches to developmental training for entrepreneurs; Develop a theoretical model comprising of identified factors which formed the base for the data collection; Develop a measuring instrument to test the relationships described in the theoretical model empirically; • Empirically test the proposed model and suggested hypotheses by means of sourcing data from entrepreneurs in South Africa and statistically analyse the sourced data; Formulate the final theoretical model to support the research objectives; and Propose recommendations based on the results of the statistical analysis. The focus of the literature study was on two main areas: trends in global developmental training, and South African initiatives to stimulate developmental training of entrepreneurs. The literature on global entrepreneurial development highlights two distinct categories for entrepreneurial development: 1) entrepreneurial education and 2) entrepreneurial training. The literature study concerning South African methodologies for developmental training for entrepreneurs, focused on current methods employed and highlighted areas on which improvements should be concentrated. From the literature study on both global and South African developmental training methods, ten independent variables (entrepreneurial culture; socio-emotional attributes; acquiring business skills; industry experience; opportunity identification; regulatory barriers; economic barriers; outside advice; formal training and informal training were identified as factors affecting entrepreneurial developmental training. All the variables were hypothesised as they were perceived to influence significantly the dependent variables: perceived global success as an entrepreneur and perceived individual success as an entrepreneur. These factors, clearly defined and operationalised, were structured in a questionnaire which was sent randomly to South African business owners. Data were collected from 332 respondents and subjected to various statistical analysis techniques. Firstly, Exploratory Factor Analysis (EFA) was conducted to assess the discriminant validity of the research instrument. Secondly, Cronbach’s alpha coefficients were calculated for each of the identified factors to confirm the reliability of the research instrument. The significance of the hypothesised relationships in the revised model were then tested by using the statistical technique known as Structural Equation Modelling (SEM) This study contributed to this specific field of knowledge.

The industry is however faced with challenges of unprecedented fluctuation of commodity prices, exchange rates, a series of divestments, host communities’ demands, oil theft, project shelving, and destruction of infrastructure. Workforce cutting and consolidations are also the order of the day and current financial risk management (FRM) systems in companies appear not to be working. FRM systems in Nigerian petroleum companies have failed because risk managers did not have one generally accepted framework to manage financial risks such as fluctuations in commodity prices, exchange rates, interest rates, and in the demand and supply of crude oil and gas. There was a need for an integrated framework that is more descriptive and that does not rely only on mathematical models, separate management of each financial risk, and specific focus on the downside risk and derivatives. Mathematical models have presented weaknesses in the identification of issues, dissemination of information, policy formulation, planning, type and the institution of risk culture or delimitation of authority and in responsibility through the organisational structure. Mathematical models could not fully reduce the identification, communication, structure, and environmental scanning of FRM to mathematical models. The present study was the first attempt at an FRM framework that integrated all the financial risks strategically and took into consideration all the critical success factors that can solve the problems and challenges facing the Nigerian petroleum companies in the long term. The primary objective of the study was therefore to develop an FRM framework for the petroleum industry of Nigeria. The study collected data using a mixed methods approach to generate quantitative and qualitative data regarding financial risks facing the petroleum industry and possible methods of managing these risks effectively. The final sample consisted of 70 top-, middle- and lower-level managers, as well as five experts in the industry. Questionnaires were administered to practitioners in the south-eastern and south-western regions of Nigeria, and semi-structured interviews were conducted with financial risk management experts in the petroleum industry. Descriptive and inferential statistics were used in analysing the data. The study succeeded in developing a framework that: provides a thorough understanding and proper evaluation of the most important financial risks petroleum companies face; identifies the type and extent of top management support needed in a strategic FRM system; identifies and operationalises the financial risk culture that should be fostered to achieve FRM success; identifies the organisational structure that supports the successful achievement of FRM; identifies and operationalises the organisation communication flow that supports the successful achievement of FRM; identifies and operationalises oversight and control to support the successful achievement of FRM; and specifies the amount of training that supports the successful achievement of FRM. By implementing this framework, petroleum organisations in Nigeria will go a long way in successfully managing financial risks in that industry.

- Description: The Republic of South Africa (RSA) became a democracy when the African National Congress (ANC) came to power in 1994. However, more than twenty years after the apartheid era, the people of the RSA are highly politicised and society still shows an extremely high level of inequality in income that is aggravated by the lack of formal job opportunities in the country. Disturbingly, early-stage entrepreneurial activity in the RSA declined from 7.8 percent in 2008 to 5 percent in 2009. As a result, the low levels of entrepreneurial activity are partly responsible for the stagnation in the structural transformation of the economy. The economy remains dependent on sectors such as agriculture and mining where looting, instability, violence and rent-seeking are endemic in spite of plentiful natural resources. As a consequence of these factors, manufacturing is becoming increasingly uncompetitive and the economy is becoming increasingly less innovative. The RSA‟s government leaders should have used the strengths of the country to minimise or rectify the weaknesses of the extremely high levels of inequality in income and the lack of formal job opportunities. Instead, these leaders identified their supporters, satisfied their short-term consumption demands, distributed jobs to the party faithful and provided social welfare to the poor. Additionally, the majority of school leavers are not pursuing tertiary studies but, with limited or little education, they still have to form part of the potential labour force of the future. The youth employment rate for 15 to 24 year-olds, in the RSA, is as low as 12.5 percent. Again, this highlights the importance of finding alternative ways to increase the population‟s participation in the economy, probably through some form of entrepreneurship. The purpose of this study was to develop a theoretical model with the main objective being to identify the factors (variables) that will promote growth, sustainability and good governance in Christian-owned Small, Micro and Medium Enterprises (SMME) within the RSA. Business is commonly viewed as a secular pursuit and religious people, particularly in Western societies, have a narrow view of the conceptual and practical application of their faith and spirituality in their businesses. As a result, the potential of businesses to influence communities, particularly with regard to issues such as social iniquities and cultural reform, good governance, responsible business behaviour, social capital, spiritual intelligence (SQ) and Christian entrepreneurship orientation appear to be, at worst, more or less irrelevant and, at best, greatly under-valued and under-utilised. The intersection of these constructs provides an understanding of how an entrepreneur‟s heightened consciousness in terms of his/her personal values and beliefs can affect his or her business activities and crucial characteristics of the entrepreneurial process, such as the recognition of opportunities, the creation of new ventures, as well as the operation and growth of these business ventures. This study uncovered a number of themes that shed light on how Christian SMME owner-managers rationalise the everyday dealings of their business lives as an expression of their faith. This study is an expression of a complex phenomenon that is extremely relevant in the present day and sharpens the focus on the important role that religious faith has to play in the field of business outcomes. Many Christian entrepreneurs express a motivational need to give back to their communities, customers and other stakeholders of the business venture. Christian entrepreneurs value intrinsic factors like purpose, passionate work and personal calling above wealth, fame, power, money, and recognition. A combination of Christian character traits forms the backbone of a Christian‟s internal power and purpose. God created people to glorify Him and this purpose is achieved through the fulfilling of a personal calling. A calling is often accompanied by a conviction of divine influence and the vocation in which one customarily engages. The call to the Christian entrepreneur is to be the salt and light in an environment (Mathew 5:13) like RSA, that is not conducive to entrepreneurial behaviour, where unemployment is very high, infrastructure is buckling under the pressures of bad management and corruption is rife.

- Description: The automotive components manufacturing sector is facing tremendous pressure to remain competitive in a global economy. The application of performance improvement techniques to optimise factor production inputs remains a key strategic mechanism to effect the necessary change towards competitiveness. The high failure rate of these programmes, however, is a risk factor that should be considered by manufacturing firms. The investment into the implementation of these programmes will yield no return if the organisational maturity profile is not considered. The expected gains may not materialise and the execution of critical projects may take much longer than required. It is for this reason that an approach towards selecting the correct Performance Improvement Programme to optimise the performance of companies is a business imperative. Through a better understanding of the relationships between Performance Improvement Programmes and Organisational Maturity Variables, implementation success rates can increase, leading to improved results and sustainability. The approach taken to this research was quantitative in nature. Various descriptive and inferential statistics were applied to the selected respondents from the Eastern Cape automotive sector. The respondents had a working knowledge of Lean Manufacturing, Total Productive Maintenance (TPM) and Six Sigma. The research instrument was administered through an online survey. The research sought to identify whether there was a relationship amongst the variables under the three identified constructs. The research also sought to establish whether there was a difference between the specific Performance Improvement Programmes’ and Organisational Maturity Variables’ relationships. This affirmed the use of a new framework that integrates the programmes on the basis of their relationship to Organisational Maturity Variables. The research also provided insight into the challenges of the industry from a performance perspective and linked these with the relationship between Organisational Maturity Variables and Organisational Performance Variables. This allowed the researcher to include this additional insight as a consideration in the integrated implementation framework developed as part of the research. The results show that good consideration should be given to the Organisational Maturity Variables as these variables are related to the successful adoption of Performance Improvement Programmes. The research also shows that Lean Manufacturing, Total Productive Maintenance and Six Sigma are related to an organisations’ maturity profile in different ways. These results support the integrated Performance Improvement Programme approach, using a common set of tools and selecting the necessary programme specific tools based on a firm’s maturity profile. The research affords industry a framework to aid in decision making considering the relationships tested as part of this research. The linkages between Performance Programmes, Organisational Maturity Variables and Organisational Performance Variables are now more specific in nature.

- Description: The Southern African Development Community (SADC) region, like most parts of the African continent, faces significant modern energy services access challenges. It is estimated that less than 45% of the SADC region’s populace have access to reliable modern energy forms and the situation is worse in rural areas where access is approximately 30%. Poor energy security is exacerbated by electricity power cuts and load shedding in almost all of the member states in the region. With the advent of battery storage, all forms of green energy have the potential to contribute to the shortfall in the supply of peaking power required to meet the daily (morning and evenings) and seasonal (winter) peaks when most power is required on the grid network. The region is endowed with vast green (renewables/low carbon or clean) energy resources. The purpose of this study is to expand the empirical body of research and knowledge on factors that contribute to widespread access success to green energy in the SADC region. Investments into green energy resources require an understanding of the unique characteristics of the energy sector in the region. In order to achieve this, a conceptual theoretical model was developed and tested empirically. Factors that influence green energy access success were identified through literature reviews and discussions with energy practitioners. All identified factors were then operationalised by carefully defining them in the context of the study. In order to test the proposed theoretical model and the hypothesised relationships, a structured questionnaire was developed and sent to energy practitioners from various sections of the energy sector in the region. STATISTICA 12 was employed to analyse relationships between variables and responses between identified groups. Pearson Product Moment Correlation (Pearson r) was employed to determine correlations between variables. Conclusions about hypotheses six (6) to fifteen (15) were made based on correlations between variables. T-tests were employed to make inferences about the views of various categories of respondents with regard to the twelve (12) identified variables. Multivariate analysis of variance (MANOVA) and Analysis of variance (ANOVA) examined associations between the dependent and independent variables with the identified categories of respondents and conclusions about hypotheses one (1) to five (5) and sixteen (16) were also made. The study finds that policy and the regulatory environment are still the main driving force behind energy access in the region. Power generation is managed by authorities’ power utility companies. Unbundling of power utilities supported by new energy business and operating models to accommodate mini and off grid power plants is found to be a key to green energy access in the region. The energy market is transforming in favour of independent power producers (IPPs) and consumers will significantly influence energy access decisions in the future. Green energy power storage to overcome intermittency will feature prominently in the success of green energy access in the region. Widespread access success to green energy will be attained when green energy access is reliable, affordable, efficient, and socially acceptable, meet the demand and reduces environmental pollution. The study recommends that strategic green energy planning must incorporate green energy infrastructure development, projects finance and human capacity development as priorities amongst SADC region’s member countries. Regional energy access enabling institutions must be strengthened; energy policies implemented with vigour and private sector participation enhanced in an integrated energy market.

- Description: The ineffective performance of school operational teams in secondary schools in South Africa reflects in many negative aspects, from team operations, disengaged educators, ineffective leadership and communication and low performance in the teaching and learning domains. The purpose of this study is not only to contribute to the body of knowledge in this educational management field, but by examining the enabling factors that drive the high performance level of these school teams, these could assist with operation that utilises more of their human capital potential. By examining these high performance factors utilising a diagnostic tool, gaps could also be identified. To achieve this purpose, the objective was to develop a theoretical conceptual model and a school analytical tool that could holistically analyse and identify the strengths and weaknesses within each school. The purpose was to identify the enabling factors that create and drive the high performance of school operational teams in secondary schools This fingerprinting or profiling of the school could thereby allow for more cost effective interventions to be implemented within each school context. The aligned diagnostic and interventions addressing the gap enabling factors, assists in the school improvement and strategic plan for the school. At present, many schools do not have the resources or skills to conduct reliable and valid self, team and needs-assessments, therefore school improvement plans and strategic plans are often not using site-based analytics. By conducting these, a more focused and scientifically based, as well as cost effective intervention, could be implemented resulting in a more effective result in best practice. The three focus areas examined in the literature study in the field of educational management and school improvement, were leadership, engagement and communication. Initially the literature study indicated, thirteen independent and mediating variables around these key areas, which formed the foundations for the development of the design and development of the survey instrument. The thesis was based on a number of theoretical frameworks from which the conceptual model was devised. The dependent variables included literature based metrics for factors of Organisational Commitment and Employee Engagement, as well as the percentage Grade 12 pass rate obtained from the average performance over the last three years at the school. All the variables were hypothesised, defined and operationalised in the design of the school analytical tool for assessing the effective performance of the school operational teams. Independent and mediating variables included: Educator Team Competencies, Perceptions of leadership, Culture Alignment, Innovation potential, Employee experience, Fairness, Hybrid leadership environment, Trust, Support, Communication as well as Infrastructure, Leader-Member Exchange and Perceptions of Learner engagement. This predominantly quantitative research study examined the effective performance levels of school operational teams utilising an ecological systems theory approach. The School Analytical Tool comprised 71 items which were subjected to validity and reliability tests. Confirmatory Factor Analysis and Cronbach Alpha coefficients were conducted on the measuring instrument. Data was collected from school operational teams which included principals, educators and administrators from twenty-nine different secondary schools, in different contexts and across three regional areas in South Africa. A total of 413 respondents participated and a response rate of 40% was achieved. Ethical permission was obtained from all the relevant parties prior to commencement of the research study. After the proposed conceptual model was devised, structured equation modelling (SEM) was used to test the hypothesised significance of the relationships between the variables in the integrated model. Two sub-models were identified: Human (Individual/Team) Sub-Model A and System (Organisation/School) Sub-Model B. These were measured by two indices, the Team Performance Index and the School High Performance Work Index respectively. These measures showed different linkages to the Educator Employee Engagement and Organisational Commitment metrics. From the SEM, three models were tested for goodness of fit criteria with version 3 showing a reasonably good fit with a RMSEA (0.056 CI 95%: 0.054-0.058), with a CFI (0.86) and a normed Chi squared of 2.24. The objectives of this thesis were therefore achieved in developing a statistically and theoretically validated conceptual model for enabling factors that drive effective school operational teams, as well as a school analytical tool (SAT) that could identify gap factors for school profiling. The practical application of school profiling utilising the SAT was also indicated by analysing a high and low performing school from different regions in South Africa, indicating the ability to identify weaknesses and strengths of the school operational teams within different contexts.

From the SEM, three models were tested for goodness of fit criteria with version 3 showing a reasonably good fit with a RMSEA (0.056 CI 95%: 0.054-0.058), with a CFI (0.86) and a normed Chi squared of 2.24. The objectives of this thesis were therefore achieved in developing a statistically and theoretically validated conceptual model for enabling factors that drive effective school operational teams, as well as a school analytical tool (SAT) that could identify gap factors for school profiling. The practical application of school profiling utilising the SAT was also indicated by analysing a high and low performing school from different regions in South Africa, indicating the ability to identify weaknesses and strengths of the school operational teams within different contexts.

- Description: Business sustainability is a fundamental concern amongst business leaders and it is imperative that business defines an environmentally and socially sustainable path to financial prosperity. This focus on sustainable business practices has been caused by the perceived contribution of businesses to undesirable conditions such as environmental and social degradation including global warming and the global financial crises. This study suggests that a leadership style that differs from leadership that is currently causing business unsustainability is needed in order to achieve the goal of sustainable business practices. This study therefore proposes a new kind of leadership, called conscious leadership. The main contribution of the study is to increase the achievement of sustainable business practices by investigating the importance of conscious leadership in achieving this objective. Convenience sampling was used to select senior managers and directors from mainly JSE listed companies. This resulted in a total of 371 usable questionnaires (317 from listed companies and 54 from unlisted companies) being received. A quantitative approach was adopted to investigate whether conscious leadership would be related to increased sustainability competencies and more effective sustainability-related corporate governance and whether these in turn would increase sustainability behaviours which would generate sustainable business practices as measured by financial, social and environmental performance. Regression analyses were conducted to investigate the hypothesised relationships among these variables. Pearson correlations and descriptive statistics were also calculated. The empirical results showed that respondents in this study regarded conscious leadership, not as a separate construct, but as a way they governed their businesses. The empirical results showed that corporate governance and systems thinking competency had a strong interactive relationship and should therefore be cultivated within business firms. Corporate governance (including conscious leadership) and systems-thinking competency were positive influencers of employee relations, equal opportunities and workforce diversity. The empirical results however showed that corporate governance (including conscious leadership) had a negative influence on profitability. The present study cannot argue for the discouragement of corporate governance (including conscious leadership), as measured in this study, because reduced corporate governance would decrease healthy employee relations and the latter would decrease the achievement of equal opportunities and workforce diversity in these firms. A decrease in healthy employee relations would decrease profitability. The most important finding of this study is that senior managers and directors of big business firms, mostly JSE-listed companies, regarded conscious leadership as an important part of corporate governance. Corporate governance that includes conscious leadership must be developed to higher levels in business firms, so that the negative and not-significant relationships to profitability as viewed by lower and high conscious leaders respectively can be changed to positive relationships.

- Description: Supply chain management in the for-profit commercial environment is a broad, far-reaching field of study, impacting on a society’s standard of living. Commercial supply chain management is the science of balancing customer service levels with least total costs. In other words, the for-profit supply chain management practitioner is concerned with customer service levels, consumer value, shareholder value, total cost optimisation and ultimately maximising long term sustainable return on investment. Commercial supply chain management differs from military supply chain management in that the latter also focuses on service delivery, but the cost is almost irrelevant. In military operations, successful results (winning the battle) far surpass the total cost parameter or the return on investment. One of the major differentiating factors between commercial supply chain management (CSCM) in the for-profit theatre and humanitarian supply chain management (HSCM) in the not-for-profit supply environments hinges on strategic intent and how to measure success. In CSCM, return on investment (ROI) is key and in HSCM, the ability to create impact becomes paramount. Regarding spend, both CSCM and HSCM are concerned with optimising operational spend, optimal utilisation of capital goods and infrastructure as well as minimising the cost of goods, works and services. Commercial supply chain managers want to spend as little as possible on operational expenses similarly to their humanitarian counterparts but humanitarian supply chain managers are also concerned about underspending of donor funded programming. Humanitarian programming often happens under difficult and dangerous circumstances. This requires a special cadre of professionals who are willing to serve the most vulnerable without exploitation and are able to deliver value often with limited or even broken infrastructure, unreliable supply and under insecure conditions. Humanitarian supply chain management leadership requires a DBA thesis balanced approach between long term strategic views whilst managing the short term outcomes. Also, humanitarian leadership needs to balance decision-making between long term strategic interventions and the ability, maturity and cost structures at functional and executional levels. This conundrum is the fundamental difference between commercial supply chain management and humanitarian supply chain management. Once one understands and respects these nuances, one can measure performance and reward appropriate corrective behaviour. Zig Ziglar once said: “If you aim at nothing, you will hit it every time”. The question that has been asked for so long has been “how to measure supply chain management efficacy in humanitarian supply environments?” This study addresses this question of developing a framework to measure supply chain efficacy in humanitarian supply environments with the view to create an enabling environment within which service levels could enhance the impact of donor funding whilst the needs of intended beneficiaries are better served. During field research, ten key focus areas and sixty-five supply chain management elements were identified. These sixty-five elements were tested via two surveys making use of the Delphi technique. Four of the sixty-five SCM elements were eliminated following the second survey due to high disagreement between the respondents, and a further two were eliminated based on expert opinion feedback from the respondents leaving fifty-nine elements being significantly important for inclusion in the framework. Three additional elements were identified by the respondents but not empirically verified and therefore not included in the proposed frameworks but could be included in future research. Fifty-seven of the sixty-five elements can be directly controlled by the SCM function. However, four of these fifty-seven elements were eliminated during the second survey and a further two were eliminated reviewing the feedback from respondents leaving fifty-one elements under the direct control of the SCM function.

- Description: The increasing demand for electricity, the rising price of energy from conventional sources and limited electricity supply are a global concern. The demand on electricity generation could be alleviated by diversifying the sources from which electricity is obtained to achieve the goals of long-term electricity supply. Diversification implies finding alternative sources of energy such as renewable energy for the production of electricity. The South African electricity system is under increased pressure to provide and maintain electricity supply to its users. Electricity production may be regarded as a key contributor to the social and economic development of South Africa. The challenges are so serious that it will gradually become increasingly difficult to extract sufficient resources to satisfy increasing electricity demand. Growth in the electricity and industrial sectors signifies profound changes in the entire energy industry. The South African power utility Eskom, supplies 94% of South Africa’s electricity but the risk of inadequate supply because of increasing electricity demand is mitigated through the employment of Independent Power Producers (IPPs) which supply to the grid. However, although a limited number of IPP entrepreneurs sell electricity to the Eskom grid, there is no enabling entrepreneurial environment in which they can thrive. There is no positive movement to inaugurate policies and processes. This has created an opportunity for Smart Grid access as a viable option to accommodate IPP entrepreneurs into the grid. Investing in renewable electricity sources may provide feasible alternatives for the electricity industry, it would alleviate pressure on current supply whilst creating an enabling entrepreneurial environment for IPP entrepreneurs and increase entrepreneurial activity. This study investigates a proposed model for an enabling entrepreneurial environment for IPPs in the RE sector that can be utilised to ensure increased entrepreneurial activity within the electricity industry. Establishing such an enabling environment would contribute positively to the alleviation of the electricity demand crisis, result in lower carbon emissions and create a sustainable, more diverse electricity generation mix. This proposed IPP industry model for an enabling entrepreneurial environment is presented to address the problems experienced at the different levels of the electricity industry. The model can be utilised to increase entrepreneurial activity while eradicating major electricity challenges at different levels in the South African electricity industry. The results indicate that that RE, in the form of solar and wind, has the potential to expand the South African electricity industry significantly. Therefore, in order to reform the South African electricity industry, stakeholders need to embrace entrepreneurship as IPP entrepreneurs. This can be done effectively by the incorporation of IPP entrepreneurs into the electricity network. However, an enabling entrepreneurial environment in which to operate must be ensured. In this study, five important variables support the establishment of an enabling entrepreneurial environment for IPP entrepreneurs. These have been identified as; Smart Grids, Entrepreneurship, Renewable electricity environment, SA policy and Stakeholder theory. An important contribution has been made towards Stakeholder Theory. This has proven to be instrumental within the RE sector of the electricity industry in South Africa, as the mentioned role players have a reciprocal role to play. Three surveys were conducted at three levels of the electricity industry, namely, at organisational, legislative and entrepreneurial levels and included Eskom Management, National Energy Regulator (NERSA) Management and Approved and Non-approved IPPs. Both qualitative and quantitative research methods were utilised in this research study. The results indicate that SA Policy is instrumental in assisting stakeholders to facilitate the IPP process and feed the power from RE generation into the network. Most respondents were positive about the role of Smart Grids in future electricity generation and their contribution towards creating an enabling entrepreneurial environment for IPP entrepreneurs. Respondents indicated that by policy decisions, greater emphasis can be placed on the results of climate change and environmental challenges. Emphasis on the incorporation of stakeholders proved imperative to this group (IPPs). The results indicated that stakeholder management is a key factor contributing to the establishment of an enabling entrepreneurial environment. The major contribution of this study is a proposed entrepreneurial model that can improve future sustainability of the electricity supply.

- Description: The purpose of this study was to develop and empirically test the Supply Chain Integration Framework (SCI framework) in order to develop a framework to address the inefficiencies experienced in the public hospital pharmacies’ Supply Chain (SC) in Kenya. Supply Chain Management (SCM) can be regarded as a vibrant business entity that is changing and evolving continually because of constant changes in technology, competition and customer demands. The study investigated and analysed how the independent variables, namely SCI initiatives, performance improvement drivers, organisation environmental forces, workforce and management support, financial factors, flow and integration, regulatory framework and information sharing and technology influenced the SCI. The SCI was categorised into three components namely: customer order fulfilment, supplier collaboration and dedicated SC as the dependent variable. The literature reviewed established that globalisation and intensive worldwide competition, alongside technological developments, creates a completely new operating environment for organisations. The researcher reviewed various models and theories related to SCI which include systems theory, value chain models and value ecology models among others. An SCI framework was then developed to capture the interacting variables within the SCI network that could be adopted for the public hospital pharmacies in Kenya. The study was conducted using a survey questionnaire (Annexure B) that comprised both open and closed ended questions that were distributed to managers in public hospitals and pharmacies in Kenya. The population for the survey was 154 public hospital pharmacies in Kenya, with the final sample comprised of 280 respondents. The study was conducted using a survey questionnaire (Annexure B) that comprised both open and closed ended questions that were distributed to 325 respondents in 154 public hospitals and pharmacies in Kenya. The population for the survey was 154 public hospital pharmacies in Kenya, with the final sample comprised of 280 respondents. Exploratory factor analysis was used to ascertain the validity of the measuring instrument and the Cronbach alpha coefficients were used to measure the reliability of the measuring instruments. Key preliminary tests performed were the Kaiser-Meyer-Olkin test (KMO test) of sample adequacy, the Bartlett’s test of sphericity and the Kolmogorov-Smirnov test (Z-Statistic test) for normality and multi-collinearity diagnostic. Analysis of Variance (ANOVA) and multiple linear regressions were the main statistical procedures used to test the regression model fit and the significance of the relationships hypothesised among various variables in the study. Statistical softwares, namely Statistica 10 (2010) and Statistical Package for Social Sciences (SPSS) Version 18, were used to analyse quantitative data. The study identified five statistically significant relationships between customer order fulfilment and workforce and management support, financial factors, flow and integration, information sharing and technology, supplier collaborations and dedicated SCI. In addition, a total of six statistically significant relationships exist between the supplier collaborations and SCI initiatives i.e. performance improvement drivers, workforce and management support, financial factors, flow and integration, information sharing and technology adoption as well as dedicated SCI. Furthermore, four statistically significant relationships were found between dedicated SCI and SCI initiatives, workforce and management support, financial factors, flow and integration, information sharing and technology adoption.

Going green: the impact of integrated sustainability reporting within JSE companies

- Description: The world is threatened by the possibility of an irreversible catastrophe that many would blame on the environmental impact of the present lifestyle, the results of which are climate change or global warming. This is clearly unacceptable to both present and future generations. If going green really means changing the way we live and pursuing knowledge and practices that can lead to more environmentally friendly and socio-ecologically responsible decisions, it is time to protect the environment and sustain its natural resources for current and future generations. Integrated sustainability reporting should be viewed as a vehicle to accomplish this global agenda of going green beyond mere legal requirements. The purpose of this study was to investigate the impact of integrated sustainability reporting (ISR) on achieving green business status within JSE listed companies. To achieve the purpose, an in-depth literature study and empirical research were undertaken using a triangulation method. After a detailed descriptive and content analysis of the collected primary and secondary data, the study found the following: Most of the JSE listed corporations’ integrated reports are not utilising the CSR, GRI guidelines and voluntary standards as effective tools to drive the process of green sustainable business. Some of the JSE listed organisations are treating financial and non-financial matters as separate issues in their integrated reports; The ISR has no impact in terms of using the NEMA framework in driving the process of green sustainable business in the JSE listed organisations; Most of the JSE listed organisations were fully aware of ecological sustainability as a pillar to drive the process of green sustainable business. They treat this pillar of sustainable development as a separate entity from socio-economic developmental issues. Most of the JSE listed corporations adhere to all the bylaws and regulations of ecological sustainability within their required certification of ISO 14001 standards in order to remain effectively certified by the auditing authority. Some integrated reports indicated much support for staff in terms of health, educational activities, labour laws and programmes that advance the socio-economic aspects of human beings; The study has found that the social pillar of sustainability is mostly supported by JSE listed organisations in South Africa - to the level of the requirements of labour relations legislation. It is not integrated with sustainability policies beyond the statutory requirements; It was further noticed in this study that integrated sustainability reports, based on the Global Reporting Initiative (GRI) principles and the King III reporting guidelines, disclose outcomes and results regarding the JSE listed organisations’ obligations, strategy and management approach which occurred within the reporting period. To address the above-listed findings, the researcher recommended that the JSE listed organisations integrate the NEMA, EMS, CSR, GRI and King III guidelines in their integrated sustainability reporting, in order to produce an effective sustainable green business in South Africa that is ecologically accountable and socio-economically supportive to all multi-stakeholders. The government and non-governmental organisations are the key players to drive the process of going green using the ISR. The government needs more structured policies and regulations that will support the National Development Plan in the pursuit of green economy in the form of grants and incentives that are beyond the present status quo.
