Academic writing in global open distance learning : case studies of an MBA programme in Ethiopia, Russia and the UK.

The study was motivated by my own experiences as a speaker of English as a second language (ESL) who has studied and taught high school courses produced in the UK, which Kachru (1988) classifies as the ‘inner’ circle, to students in the ‘outer’ circle in Swaziland. The central focus in this study is students’ academic writing in English in an open distance Master of Business Administration (MBA) programme provided by the Open University (OU) UK, in different parts of the world to students from diverse cultural, geographical, linguistic and educational backgrounds. The main focus of this study is students’ academic writing in the medium of English in the contexts of Ethiopia, Russia and the United Kingdom. In order to explore students’ writing and their experiences of engaging in such writing, I draw on recent studies which view reading, writing, and other aspects of communication as fundamentally social activities. In order to explore their writing in its social context, I draw on a range of data sources: students’ written assignments, interviews with students and tutors, pro-formas, and course materials. The central argument in this thesis is that speakers of English as a foreign language (EFL) and speakers of English as a second language (ESL) studying an open distance course in their diverse local contexts may be disadvantaged in a number of ways; in terms of their resources for writing, their understanding and experience of English, their background knowledge and the inapplicability of course concepts in their contexts. The study also highlights tensions surrounding the provision of UK based courses to students in different parts of the world and acknowledges the difficulties of developing courses which are accessible and relevant to diverse groups

Measuring fiscal incidence and its redistributive impact in Swaziland

According to Swaziland's National Development Strategy, the country's objectives are to improve the standard of living of all citizens, eradicate poverty, create employment, enhance gender equality and improve the country's human development ranking from a low human development rank to a high human development rank by 2022. Persistent poverty and the unequal distribution of income have, however, posed significant challenges for the country in achieving these development goals. This study assessed the extent to which the government of Swaziland has been able to use its fiscal policy, in particular the tax and public expenditure policies on health and education, to redistribute resources and reduce income inequality. The study also investigated the incidence of out-of-pocket expenses incurred by households in accessing public health and education facilities. Based on both the Swaziland Household Income and Expenditure Survey data collected in the 2010 national survey and the government's 2010 budget, the study found that the tax policy had had a slight redistributive effect, as the Gini coefficient, had dropped from 0.7909 (pre-tax income distribution) to 0.7424 (post-tax income distribution). Public expenditure on education improved the income of poor households by 32.83 per cent and had led to a further reduction in the Gini to 0.7185; however, public expenditure on tertiary education was poorly targeted as rich households were deriving a higher benefit than poor households. Out-of-pocket expenses on health were not regressive despite the fact that there was a low usage of health facilities by the low income households. On the other hand, education out-of-pocket expenses were found to be regressive and had a negative impact on the progression rates from primary education to higher learning institutions in the low income households. Overall it would appear that the country's fiscal policy has led to a reduction in the country's income inequality. However, the country has not made significant progress towards the achievement of its development goals, with the 2010 national household survey revealing that the poverty rate was still relatively high at 0.630, while the 2010 labour force survey revealed that unemployment was still high at 0.406 and the 2014 human development report showed that the country was still ranked low in terms of human development

The chemical composition and potential nutritive value of the foliage of four subtropical tree species in southern Africa for ruminants

The foliage of three Combretum species, C. apiculatum, C. molle and C. zeyheri, as well as that of Colophospermum mopane was collected over a period of two years. The chemical composition, in vitro organic matter digestibility (IVOMD) and the rumen degradability of dry matter (DM) and nitrogen (N) were determined on these samples. Mean values for crude protein (CP) concentration varied from 92 g/kg DM for C. molle to 141 mg/kg DM for C. mopane, the neutral detergent fibre concentration from 323 g/kg DM for C. apiculatum to 392 g/kg DM for C. molle and that of acid detergent fibre from 247 g/kg DM for C. apiculatum to 355 g/kg DM for C. molle. The calcium (Ca) concentration in the foliage was high (8-16 g/kg DM) compared to the phosphorus (P) concentrations of between 0.8-2.1 g/kg DM, resulting in an average Ca: P ratio of 9.3: 1. The foliage contained relatively low levels of sodium (Na), 0.041 g/kg DM, based on beef cattle standards. The IVOMD ranged from 53% for C. mopane to 64% C. apiculatum and the rumen degradability of DM from 78% for C. molle to 94% for C. apiculatum. The DM degradability was substantially higher than that of nitrogen, which varied between 47% for C. apiculatum and 60% for C. zeyheri. It was concluded that the foliage tested would not be suitable sources of N to supplement protein deficiencies in low quality herbage. Furthermore, browsers would require additional sources of P and Na to avoid deficiencies in these elements.

Exploring Project Complexity Relations to Scope Changes in Construction Projects: A Case Study of NEC Projects in South Africa

Construction projects are of very complex nature, and subject to circumstances of high uncertainties and risks due to the interdependences of activities and processes in the project performance.  As a result of the dynamic complexities inherited in construction projects, changes in the scope of work are inevitable. Of particular concern is that, when scope changes are introduced in a project, contractors follow a systematic procedure in managing the changes, but with poor planning and implementation thereof because the project complexities that underpin the scope changes are not fully understood. Therefore, despite that complexity is an inherent and defining feature of construction projects, studies in the literature have failed to grasp and present the dynamics of project complexity which underlie the scope changes in the delivery of construction project. The TOE (Technical Organizational Environmental) framework was adopted and applied on a multiple-case study research design in order to explore and denote project complexity relations to scope changes in construction projects. Through a content analysis procedure, six key elements of project complexities that relate to scope changes in the construction projects has emerged. Understanding these complexity elements could enable the project management team to apply a front-end planning approach in the initiation phase of the projects in order to better manage scope changes in the execution phase of the project, and eventually to improve the project performance

Internal democracy in the ANC or, did the Polokwane Revolt challenge Michels' "Iron law of oligarchy?"

Can political parties be democratic? This is one of the larger theoretical questions that have to be asked. The ANC has been the governing party for the last fifteen years in a democratic South Africa. For the last fifteen years the ANC has ruled with a majority, reaching the symbolic two-thirds majority in the 2004 elections, which it subsequently narrowly lost in the 2009 elections. Internal party democracy is particularly important in states that are dominated by one party, where there fewer effective ways of keeping the government accountable. The ANC has exhibited worrying trends over the last fifteen years towards suppressing dissent in the party, despite its constitution stating that members can raise their grievances within party structures. In a state dominated by a single party, as in South Africa, internal battles within the ruling party play out in the public realm. We have seen public institutions like the NPA and the SABC being used by various factions within the ANC to settle ‘political scores’ and more importantly to stop challenges posed to the current leaders of one faction. The manipulation of these institutions by elected leaders does not bode well for the country. Internal democracy issues have thus become issues for the entire countr

A systematic risk management model for construction project management: a case study of the new infrastructure project in the University of Mpumalanga

The construction industry has become the significant player in the economy of many developed and developing countries in the world. The industry contributes to the Gross Domestic Product (GDP) and employment rate of many nations. As such, the industry is the engine for the economic development and growth across the world. Recently, African countries have received global attention due to its calls for massive infrastructure development and maintenance thereof. Accordingly, the South African government has adopted a National Infrastructure Development Plan (NIDP), which seeks not only to transform the economic landscape of the country, but also to support the integration of the African economies through infrastructure development. To ensure that the execution of these infrastructure projects is successfully delivered in terms of time, cost, and scope; project risk management in the construction industry has become an important area of interest in the execution and delivery of the infrastructure projects. However, the constantly increasing complexity and dynamics in the delivery of construction projects have serious effects on the risk management processes during the execution of the project. In practice, risk methods and techniques have proven to be unrealistic when using the traditional risk management approach in the context of the complexity and dynamic environments wherein construction projects are delivered. Worryingly, project management practitioners in engineering and construction projects still lack the holistic and systematic insight and understanding of construction projects when applying the risk management procedures in the complex and dynamic projects environments. As a result, there are growing reports of unsatisfactory delivery of construction projects in terms of time, cost, quality, and environmental objectives. In this regard, the call for embracing the systems thinking paradigm as the alternative approach that will provide more clarity in dealing with the complex management challenges and which will gradually substitute the traditional theoretical approach of dealing with construction project management, is becoming prominent. Against this background, this study uses a multiple case study approach to explore how a systematic risk management approach could be developed and applied towards successful delivery of construction projects, and subsequently to propose a systematic risk management model that is designed to depict and grasp the underlying complexities and dynamics embedded ix | P a g e in construction projects. The choice of the case study design is founded on its utility and appropriateness for in-depth investigations into phenomena in its context as well as its usefulness for exploratory studies. Therefore, to explore the risk management phenomenon in real-life settings, the unit of analysis in this study was based on three construction projects built in one of the new Institutions of Higher Learning in South Africa during the period between 2017 and 2019. Notwithstanding the unique characteristics of these projects, the complexity and dynamic environments of these projects also emanated from the facts that i) the successful delivery of the projects was a predecessor activity to the academic schedule and activities; ii) this was one of the first universities to be built by the democratic Republic of South Africa; and, iii) the construction contract used for the delivery of the construction projects is relatively new to the professionals in the country’s construction industry. This qualitative case study design has its backbone in the constructivism philosophical paradigm which is underpinned by the ontology that there are multiple realities as conceptualized, experienced, and perceived by the people in their real-life situations or natural settings. Accordingly, the construction professionals, projects’ documents as well as field work observations were purposively chosen as the essential and reliable methods of data collection for this case study. For analysis, a conventional content data analysis methodology was applied on the empirical data that was obtained from the multiple data sources to provide a clearer understanding of the contexts in which the risk management for construction projects is performed. Accordingly, a qualitative data analysis software system called MAXQDA was used to enable the performance of data coding, managing coding, and eventually the retrieving of the coded segments in a form of visual models and summary tables. Ultimately, the qualitative content analysis approach in this thesis was performed in terms of a ‘critical filter of thick description’ which involved a balanced approach between the deductive analysis and the inductive analysis processes. With the assistance of the MAXQDA, performing the multiple levels coding and analysis processes in this thesis has not only been efficient, but also more reliable. To shed insight into the empirical findings of the study, a hybrid theoretical framework has been applied in the discussion and interpretation of the findings. The theoretical framework of this study is underpinned by the complexity theory and the theory of systems engineering. The applicability of these theories in this study is essential in providing a x | P a g e systematic and logical explanation of the practices of risk management in construction projects and further helps to explain why particular events occurred in the processes of risk management. Eventually, the theoretical framework has enabled the designing and developing of a systematic risk management model that will assist in depicting and grasping the underlying complexities while supporting proactive decision making in the delivery of construction projects. To this end, this study has made several major contributions in three multiple folds in the body of knowledge. Firstly, this study makes theoretical contributions by developing an empirically underpinned systematic risk management model which provide more clarity on comprehending the multifaceted and complex risk factors embedded in construction projects. Secondly, the qualitative case study approach and the associated analysis methods thereof in this thesis provides novelty and lays the groundwork for future research and methodological replicability in another similar phenomenon elsewhere in the world. Thirdly, this study has gone some way towards expanding the understanding and the basis for managerial decision making in relation to front-end planning and proactive approach for risk management, and eventually to improve projects’ performances on cost, time, scope, and environmental sustainability. In this regard, the key practical implication for project management practitioners is that the adoption and embracing of the systematic and holistic thinking approach in the risk management processes could enhance the successful delivery of construction projects. In the literature, there is paucity and need for more research into the exploration and analysis of the integration and interplay between the systems engineering and complexity perspectives and the other knowledge areas in the PMBOK. In conclusion, this thesis therefore argues that to address the deficiencies in risk management practices during construction projects’ delivery, the solution requires a paradigm shift from the traditional linear approach which, by design, overlooks the complexities, non-linearity and interdependences of the elements that are underpinning and characterizing the nature of the contemporary construction projects. Therefore, this thesis supports the increasingly emerging debate on the discourse that the superior traditional and linear approaches do not solve the current problems, and as such they should be replaced with the systems and holistic thinking approach that will provide more clarity in dealing with the complex management challenges in contemporary construction projects.Thesis (PhD) -- Faculty of Engineering, Built environment and Information Technology, School of the built Environment 202
