- 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: Integrating Knowledge Management maturity with associated Continuous Improvement efforts in order to remain competitive, is absent in most Operational Excellence initiatives. Furthermore, the intertwined relationship of Continuous Improvement and work development becomes a crucial focus area for organisations that wish to establish a continuously evolving management system consisting of core values, methodologies and tools with the aim of creating more satisfied customers with less resources. The old industrial paradigm that focused on labour, capital, materials, and energy viewed technology and knowledge as external influences on production. This framework is now being challenged and a new trend is emerging. This trend seeks to transform the old industrial system to that of a knowledge-based which one can lead to innovation and hence economic advantage. Continuous Improvement as a concept has roots in many other fields, including social-technical system design, human relations progress and the discussion surrounding ‘lean manufacturing’. This study will focus on Continuous Improvement as a noun, referring to on the outcome of the process of a stream of emergent innovations. The primary objective of the study is to create a model that will present an organisation with a three-layer knowledge reference process grid, which will align and depict the surrounding business knowledge functions, knowledge-enabling processes and knowledge-manipulating processes aiming for enabling Operational Excellence. This study promotes the theory that the cognitive domain layer, functional domain layer and resources layer of an organisation can be increasingly stimulated by focusing effort through Continuous Improvement routines towards the associated inter-organisational knowledge processes sustaining Operational Excellence. The proposed model is structured to review, compare, evaluate and integrate existing Knowledge Management practices of ii an organisation within the context of clear definitions for important concepts of Knowledge Management. Additionally the model provides an assessment instrument for evaluating the organisation’s Knowledge Management maturity level. The study concerns itself with two concepts towards business value creation which will lead to increased Operational Excellence. Firstly, the maturity of Knowledge Management processes, and secondly the level of the organisation wide process of focused and continuous incremental improvement namely, Continuous Improvement. A case study with PriceWaterhouseCoopers was concluded and an on-line Internet survey was used with a stratified sample from knowledge workers to test the factors from both a Knowledge Management and Continuous Improvement perspective. These factors were verified by means of a hypotheses network, describing in a structured and descriptive way, the importance of Knowledge Management and Continuous Improvement collectively on sustainable Operational Excellence as an integral development of Operational Excellence. With respect to Knowledge Management practices, the hypothesis network proposed at least three domains, which of knowledge generation, knowledge mobilisation and knowledge application as important input to the proposed process grid of knowledge development and associated layer elements. From a Continuous Improvement principles perspective it is apparent that elements from Continuous Improvement routines and Continuous Improvement characteristics are associated with the organisation Continuous Improvement ability. These findings are also a result of the deliberate design of processes, tools, structures and environments with the intent to increase, renew, share or improve the use of knowledge represented in any of the three elements for structural, human and social of intellectual capital. The proposed model combines the framework of the Boyd cycle as it is conceptualized as self-assessment activities, for it becomes possible to use them as basis of a self-assessment with sense making navigational properties across iii the proposed knowledge process grid for the model. The model will facilitate the concept of a three-layer knowledge reference process grid, which represents the main components of the knowledge processes within the cognitive domain layer, functional layer and resources layer of an organisation. The proposed model will deliver a single value that co-exists with the Knowledge Management maturity level and Continuous Improvement readiness index rating attained. Logical relationships to dynamic, evolving and flexible enabling Knowledge Management practices for each layer of the proposed three-layer knowledge reference process grid will be integrated as output of the proposed model. The research has limitations as Knowledge Management practices were measured using a subjective norm scale. It is suggested that a more comprehensive measure of Knowledge Management maturity processes may be needed to represent this construct. The complexity of the proposed model and the number of associated variables included in the results need further confirmation using possible multiple samples and additional measures of Knowledge Management maturity and Continuous Improvement readiness elements. The benefit of the proposed model as a practical Operational Excellence tool is to overcome the perceived gap of implementing Knowledge Management practices and Continuous Improvement principles collectively to deliver and sustain Operational Excellence.

- 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: 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: Professional associations and professional relationships are a feature of the social structure of all advanced societies. Professional associations perform or provide a number of functions and services for professionals and for the organisations employing them: Continuing education, admission to practice, certification and credentialing, educational standards, enforcement of standards, codes of ethics, and standards of performance, meetings, social activities, newsletters, and journals. Professional association membership is therefore very valuable to professionals and, in turn, for the organisations which employ those professionals, because of the wide variety of important functions served and services provided by such associations. This value cascades through to the economy of the countries in which the associations perform. This study seeks to contribute to the increased effectiveness of professional associations in South Africa by assessing the level of organisational effectiveness within these associations, and the factors that affect such effectiveness. It is hoped that this research will provide the necessary information to enable senior stakeholders within the associations to make better decisions, and formulate better strategies to improve their effectiveness. If challenges of ineffectiveness are not addressed, the risk is that these associations might not achieve optimal effectiveness and growth, with negative impact on the professionals they serve, and the economy. Conversely, and optimistically, improvements in the effectiveness of professional associations, will positively impact the professionals they serve, with cascading benefits to the economy. Convenience sampling was used to target the senior staff or office bearers within the 48 SAQA registered professional associations in South Africa, at the time of survey. Self-constructed instruments were used to measure the variables included in the hypothesised model. Open-ended questions were also included in the questionnaire in order to capture qualitative information about professional associations. Using STATISTICS Version 10 (2010), the data analyses included exploratory factor analyses, the calculation of Cronbach alphas and Pearson correlations, and the content analysis of qualitative data. The most important finding of this study is that being an effective learning organisation (ELO) is an important indicator of a PA’s organisational effectiveness. To be an ELO means that the PA should continuously strive to learn and improve by conducting research that benefits the association itself, its members, its sector and its country. It is therefore important that PA’s focus their efforts on becoming effective learning organisations by planning and directing their resources on achieving this objective. It means that PA’s must employ or contract in intellectual resources that would enable them to stay at the cutting-edge of services that their members and clients want. This would require PA’s to ensure that they have the continuous services of high calibre researchers. The second important finding of this study is the indication that membership growth is another measure of a PA’s organisational effectiveness. It has already been reported above that being an ELO drives membership growth. The fact that being the first-mover in the industry increases membership growth is an indication that PA’s should capitalise on this strength, by always striving to be the first in everything its members and clients require, or will require. This calls for PA’s to conduct continuous environmental scanning, and the required research and development to deliver products and services first to their members and clients. The fact that competitive characteristics drive membership growth indicates to PA’s that they could attract more members if they maintain and improve service levels; continuously and effectively lobby government for better services for their members and clients; develop and deliver unique services to their members and clients; protect themselves against imitation of their resources and skills, outperform their competitors; and continuously enhance their credibility compared to other professional associations.

- Description: Globally, organisations have recognised the strategic importance of knowledge management (KM) and are increasingly focusing their efforts on practices to foster the creation, sharing and integration of knowledge. Whilst most research in Knowledge Management (KM) has focused on the private sector, there is a breadth of potential applications of KM theory and practice for government agencies to adopt in search of resolving pertinent problems. The purpose of this study is to examine the factors that influence the effectiveness of knowledge management towards collaborative problem solving in government. What is missing is research-based evidence of the factors that influence the main factors for knowledge sharing across government agencies. Given this gap, the researcher addresses the research question: In government agencies mandated to resolve issues of crime, what are the key factors required which support and influence the collaborative sharing culture? Upon analysing the data, the researcher found the following key factors as being determinants on knowledge management: organisational culture, learning organisation, collaboration, subject matter experts and trust. The two factors – organisational culture and learning organisation were identified as the most significant factors which lay as the root or core for the ‘knowledge tree’. Once these roots are in place, the other factors will gain their significance on knowledge management. These findings serve to extend the findings of the existing literature within the government sector. This study is important because the findings provide government agencies with critically important information to guide their actions towards ensuring a knowledge sharing culture is embedded in government. Whilst the empirical findings do not focus on databases or information technology specifically, it is important to acknowledge the use of both technology and people. The main concern is with managing an organisation’s knowledge assets: creating, storing, protecting, disseminating and using mission-critical knowledge. When people need knowledge, is it the right knowledge and is it timely and easy to locate and access? Is this precious commodity updated as learning occurs and better ways of doing things are discovered? The awareness of the value of knowledge to a business, coupled with its leadership, acts as an integrator that improves cross- functional communication and cooperation. Shared knowledge not only makes for a more effective, efficient and agile organisation, but creates a common perspective and culture that produces a natural consistency of successful decisions and actions. The collaborative knowledge tree model proposed in this study uses the analogy of a tree when viewing South African government agencies as the branches of a collective tree (government). This ‘tree’ requires leaders and policy making to ‘dig deep’ into understanding the roots of the tree in order to ensure that the appropriate ‘seeds’ are planted such that the tree grows and is able to provide the necessary fruit required. Ultimately, as suggested by former President Thabo Mbeki (2012) in his address, the role of knowledge would thus be seen as a collaborative means towards the betterment of society.

- 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: 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: 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: The aim of the research is to quantify the HIV prevalence in human resources of forestry contracting businesses and to develop a management framework to promote economic sustainability of forestry contractors. HIV tests were conducted in the forest industry on the employees of contracting concerns from 2002/2003 to 2004/2005 with an accompanying questionnaire to collect demographic data. The HIV test results were analyzed with the demographic data to determine relationships between HIV prevalence and demographic factors. Contractors responded to a questionnaire on the effect of HIV and AIDS prevalence on (their) contracting businesses. The questionnaire also collected information about HIV and AIDS interventions and assistance to HIV and AIDS affected employees. Key stakeholders of other forestry sub-sectors were interviewed to facilitate comparison of the different sub-sectors and to establish if there were major differences between the sub-sectors, however, the focus was on the human resources of the forestry contracting sub-sector. The research results indicated that the HIV prevalence was increasing for the research period and was, in some regions, exceeding 40 per cent. The highest prevalence was recorded in the Highveld and Zululand regions and the lowest prevalence in the North-Eastern Cape. The HIV prevalence for females was constantly higher than the incidence for males and the ratio of males to females (all regions) approximated 68 per cent to 32 per cent. The high prevalence of HIV results in major social and economic impacts. The economic impact is aggravated through regulation (due to perceived market failure) and a bid for more equal distribution of wealth in the economy. The result of the sum of the impacts alludes to a conversion from labour to capital; however, to make well-informed decisions, various scenarios should be simulated to establish the optimum labour to capital ratio. The research further established that appropriate staffing is increasingly difficult and that the development of human capital is under pressure due to the high prevalence of HIV and AIDS. HIV and AIDS mitigation programmes will make a significant contribution to the return on human capital assets, as the economic life and productivity of such assets will be enhanced by such interventions. The management framework developed was assessed to be visually acceptable and useful by domain experts; however, to realise the full potential of the framework it should be used with anticipation of the research results regarding prevalence and future estimated AIDS releases and in conjunction with industry cost simulation models.

- Description: The Information and Communications Technology (ICT) skills shortage is of national and international concern. Modern business practices require the implementation of new technologies supported by a workforce with current and diversified ICT skill-sets. Acquiring suitable ICT skills has become a difficult task and employers are seeing government intervention at all levels. The school system in South Africa is under increased pressure and is faced with continuously declining matriculation pass rates, specifically in subjects such as science and mathematics. Schools are experiencing a decline in the number of scholars (learners) enrolling for the Information Technology (IT) school curriculum. The IT curriculum at school level is being criticised; under-prepared teachers are blamed and lack of suitable facilities highlighted. Surveys conducted amongst grade 9 and grade 12 scholars in the Eastern Cape have shown that scholars are not considering careers in ICT. Teachers, career/guidance counsellors and parents contribute to scholars' career decisions and are not encouraging scholars to pursue careers in ICT. Tertiary institutions in South Africa and internationally, are experiencing a decline in student enrolments and in pass and throughput rates. Industry is holding tertiary institutions responsible for not providing the “correct” ICT graduate skill-sets and passing an insufficient number of quality ICT graduates desperately required by industry. The accreditation of computing degree programs, such as Computer Science (CS), Information Systems (IS) and Information Technology (IT), collectively referred to as CIT, offered by tertiary institutions is becoming an international requirement. The ICT industry is constantly changing and new job requirements and new career opportunities are frequently introduced. Graduates entering the ICT industry should have acquired knowledge about ICT career tracks in order to specialise and choose a suitable career path. Tertiary CIT degree programs should further be linked to specific career tracks and provide a multi-disciplined education to graduates. ii ICT graduates working in industry utilise skills obtained in under-graduate and post-graduate CIT degree programs. The ICT graduates have also obtained valuable skills working in industry, including business skills and soft skills. ICT skill surveys have identified the graduate skills gap, indicating ICT skills industry requires from graduates completing tertiary level qualifications. ICT graduates working in industry, for example indicated that programming in some cases is over-emphasised at school and tertiary level and that soft skills are ignored by tertiary institutions. An ICT Graduate Skills Classifications Framework is developed to address the graduate ICT skills gap and highlight important business skills, soft skills, technical skills and programming skills required by industry. In this thesis, an Industry ICT Value Chain Model is further developed that suggests a holistic approach to the problems experienced at all levels of ICT skills development, including government, industry, tertiary education institutions and at school level. Results from a number of research surveys conducted along the proposed Industry ICT Skills Value Chain Model indicated that problems exist at all stages in the value chain and that the problems can only be addressed involving government, industry and tertiary institutions collectively. A number of interventions is required and the support from industry is essential in achieving overall success in addressing the ICT skills shortage in South Africa. A proposed Industry ICT Skills Value Chain Model that can be utilised to address the ICT skills shortage in South Africa is presented.

- 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 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: 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.

- Description: The world agricultural industry, despite numerous supply and demand challenges, has to significantly increase its production capacity to satisfy the increased demand for food and successfully address the issues surrounding food security. Access to credit is however a key enabler in this regard, while a lack of it limits the adaptive capacity of agricultural producers. The financing needs of agricultural producers however vary and are influenced by the different production systems which have different investment, revenue and risk patterns. The sector is unique in that the risk and uncertainty in agriculture are increased by the nature of agricultural production systems, which is in many cases driven by unpredictable external factors such as adverse weather conditions. In addition agricultural production systems also function within the total food system which consists of a number of interrelated subsystems, each presenting agricultural producers with a unique set of risk factors that need to be taken into account. The development of new and innovative financing solutions for the sector therefore requires a thorough understanding of the multidimensional nature of agriculture and the unique characteristics of the sector. The purpose of this study was to contribute to the development of new and innovative financing solutions for the agricultural sector in South Africa.

- 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.

- 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: 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: The humble beginnings of business incubators date back to the 1970s in the USA and United Kingdom, where abandoned industrial buildings were converted to rent out to small businesses. South Africa (SA) was first introduced to business incubation in the 1980s when the Small Business Development Corporation (SBDC) established a number of business ‘hives’ and provided business space to entrepreneurs to operate their businesses. In their most basic form, business incubators provide a safe and nurturing environment for entrepreneurs to establish their small businesses. While in incubation, the Small and Medium Enterprises (SMEs) are supported with a number of services which assist their growth and development until they are able to exit the incubator as sustainable and viable businesses. Global incubator models have matured significantly, and now include assisting with business idea generation, accelerating business start-ups and commercialisation processes, and identifying high-growth orientated SMEs to assist them with gaining market access. The establishment of business incubators was a government-driven initiative, and more than 33 SME incubators exist in SA. Most of the incubators are government-funded, and have focused on the establishment and growth of SMEs to act as a catalyst to promote economic development and alleviate socio-economic challenges such as unemployment and poverty. Despite these noble objectives, incubation in SA has not been fully utilised, and a high SME failure rate still prevails in the country. One of the reasons for SME failure may be ascribed to the lack of an enabling SME incubation environment in SA. When compared to other developing countries such as Brazil with as many as 400 incubators, it is clear that the SA incubation industry still needs further development. The purpose of this study therefore was to ascertain the best practices of global business incubators in both developed and developing countries, and how SA incubators could learn from these best practices to create a more conducive and enabling SME incubation environment. Background literature on business incubation with a specific focus on best practices in world incubators in both developed and developing countries, was reviewed. Some of the literature reviewed included Aernoudt (2004), Buys and Mbewana (2007) and Chandra (2009). From the literature review, four main best practice areas were identified, namely strategic focus, sources of funding, incubator services, and the role of government. The study followed a qualitative approach, and an interview schedule was developed to seek the perceptions of incubator managers on how the four identified best practices can be utilised to create an enabling SA incubation environment. A survey was conducted by interviewing 14 incubator managers (twelve government and two private) in SA. Data was collected over a six-month period, using face-to-face and telephonic interviews. Data was analysed using the content analysis, constant comparison, grounded theory and case study methods. The biographical profiles of the incubator managers and incubators were presented in case studies. An initial analysis was made to identify themes and sub themes within the four best practices explored, using the constant comparison method. Thereafter a provincial comparative analysis was made, as well as a comparison of government funded versus privately funded incubators. The findings suggested that there is a relatively high turnover in incubator management, and that they often do not have incubator management experience. A provincial comparison of SA incubators revealed that their strategic focuses are greatly influenced by the industry prevailing in the various provinces. All SA incubators provide pre- and post incubation services, but few are utilising virtual incubation. Most SA incubators are government-funded, and some use a hybrid funding model. It was evident that most SA incubators are aware of government policies and programmes available to assist them on local, provincial and national levels. A comparison of the best practices of two developing countries and three developed countries, as well as suggestions made by SA incubator managers indicated that SA has indeed followed best practices from both developing and developed countries, but there are areas of non-alignment which provide scope for improvement, to create a more conducive and enabling incubation environment. This study recommends that incubators should have an entrepreneurial focus, and reposition and align their strategic focus with government policies and instruments. SA incubators must pursue opportunities for virtual incubation as well as linkages with academic institutions, in order to offer value-added services such as research, development and commercialisation of the product ideas. Incubators in SA must pursue a hybrid funding model with a combination of government and private funding, and generate some or their own income. With regard to the role of government, it is recommended that the roll-out of more industry-specific incubators be privatised, and that an overseeing body for incubation be established.

- Description: Scientists started to study the relationship between changing weather patterns and the emission of carbon dioxide (CO2) and other harmful gasses. They soon discovered compelling evidence that CO2 concentration and other gases have been increasing and it was causing temperatures to increase in certain areas on the earth, which disturb historic weather patterns. Climate change has become a very popular field of study in the modern science. Europe first introduced measures to reduce carbon emissions but it was the Kyoto in 1997 where global leaders were asked to participate in a joint protocol to reduce greenhouse gases. South Africa responded to climate change challenges in 2008 with the Long term Mitigation Scenarios (LTMS). The Integrated Resource Plan for electricity to 2030 was developed from the LTMS scenarios and after some major amendments it was accepted and promulgated by Government and has recently been included in the National Development Plan to 2030 (NDP). There are concerns about the achievability of some of the objectives listed in the NDP and this study explored the IRP2010 as the proposed strategy to meet energy demand and reduce emissions. The purpose for this study was to answer this question: Is there an optimum climate change mitigation strategy for South Africa and how can the effect thereof be simulated on economic growth? Through primary and secondary research during the study it was possible to define some 32 categories of energy producing assets that are commercially active or nearly market-ready. The characteristics of the various assets and the relevant fuel are defined in mathematical equations. It was found that the three portfolios that matched the 450TWh electricity requirement would perform substantially better than the NDP portfolio in terms of cost and similar on emissions with marginally fewer employment opportunities created. The proposed electricity strategy in this study was 390TWh and 33.5 Million tonnes of oil consumption by 2030. This strategy was substantially more affordable than the 450TWh strategy. Trends in the Supply and Use tables since 1993 were studied and then forecasted to 2030 to determine consumption levels on electricity and liquid fuel into the future. It was found that electricity demand is seriously overestimated and South Africa would end up with large excess capacity in electricity infrastructures if the NDP energy strategy (IRP2010) is implemented. It is concluded that the NDP energy strategy to 2030 is based on an incorrect electricity demand forecast. It would lead to excessive investment in an electricity infrastructure. Government has confirmed that part of the new infrastructure would be nuclear. It is also found that NDP has not clearly supported nuclear as part of the strategy. Nuclear is partly the reason why the capital requirement of the NDP portfolio is so much higher than the other portfolios. It is the conclusion of this study that South Africa do not need to invest in a nuclear build programme as the electricity demand would be adequately covered by adding the new Medupi and Kusile power stations, Ingula pump storage scheme, some wind and solar renewables, electricity from cogeneration, biogas, biomass, small hydro and imported hydro from neighbour countries. To invest in electricity capacity to generate 450TWh annually by 2030 would result in excessive energy cost, GDP growth could be up to 1% lower due to underperforming capital investments in the electricity infrastructure and higher energy cost would lead to a decline in global competitiveness.
