- Description: Special needs education has always provided special challenges to school administrators, policy makers and teachers. The world-wide move towards inclusive education as an alternative to exclusive education or casual mainstreaming has resulted in significant developments in Namibia in the past decade. Global educational reforms have focused on education for all as well as inclusive education and Namibia is signatory to several conventions and declarations in this regard. Research in this field has largely focused on the role of the inclusive teacher, and of course the special needs of the learners. Little or no attention has been paid to possible managerial and organisational challenges which accompany the move to inclusive education. This thesis seeks to critically investigate the managerial implications of inclusive education. The focal point of this research is to gain a clear understanding of the managerial implications in an inclusive school for learners with visual impairment, chiefly through an exploration of the experiences of management members of the inclusive process. The research is located within a qualitative research paradigm, which is subsumed by a phenomenological model. The data gathered through in-depth interviews include many anecdotal accounts that provide insight into the ways respondents reacted to experiences at the inclusive school. The main findings of the research are highlighted and discussed. Recommendations arising from a critical analysis of these main findings are presented.

- Description: This qualitative study focuses on business level strategy adopted by Twizza to compete in the bottom of the pyramid market in the Eastern Cape, South Africa. Twizza enjoyed huge success between the years 2010 - 2014 as a medium to large sized manufacturer of carbonated soft drinks in the Eastern Cape. In light of this, the current study seeks to answer the following: What business level strategy did top management at Twizza adopt to compete and grow in the BoP market in the Eastern Cape, South Africa? The study takes the form of a case study to explore and understand the patterns of decisions adopted by Twizza’s top management in competing at the bottom of the pyramid. As such, the main objective of the study was to identify the business level strategy adopted by Twizza which enabled their superior performance within the BoP market. The study adopts Porter`s typology to explore business level strategy. Stratified, purposive sampling was used to identify 4 top managers as participants in this study. A total of 7, semi-structured, interviews were used to collect critical incidents from top management of Twizza. This was the primary data used in this study. This type of data was combined with relevant information which was gathered via published press articles and on-line commentary. The study found that central to Twizza’s business strategy were four pillars, namely, strict control and management of manufacturing costs, product quality equal to that of market leaders, the ability of the organisation to manufacture its own raw materials and ability to ensure product availability to the market to the market. These findings reveal that Twizza employed a hybrid strategy, anchored by cost leadership. Thus, Twizza incorporated elements of differentiation and best value strategies to offer its customers affordable quality.

- Description: Governments around the world want to deliver better education, better health care, better pensions and better transportation services. They know that impatient electorates want to see change, and fast. But, the funds required to meet such expectations are enormous, particularly in the many developed economies where populations are aging and the public sector's productivity has not kept pace with that of the private sector. The need to get value for money from governments at all levels is therefore under the spotlight as never before. However, cost-cutting programmes that seek savings of 1 to 3% per year will not be sufficient and, in some cases, may even weaken the quality of service (Bhatia & Drew, 2006). One of the key innovative means to improve productivity, and do more with less, is through the implementation of lean initiatives. The purpose of this study is to conduct an 'Assessment of the status of lean implementation at selected SARS (South African Revenue Service) branch offices'. Literature review was conducted to investigate the origins of lean and how the service industry tapped from this philosophy, which was initially developed for the manufacturing sector. The lean philosophy has now been widely adopted in various service industries, from government agencies such as the South African Revenue Service to financial institutions such as ABSA bank, including the healthcare industry. The findings of the research indicated that even though the organisation has made a strategic decision to implement lean, this has not been entirely successful as there is a lack of understanding of lean among managers and team leaders. There are some pockets of excellence though. The researcher recommends that a comprehensive road map be developed to guide the organisation into a sustainable lean implementation.

- Description: The South African fast-food industry has experienced substantial recent growth. However, as consumers have incorporated more fast food into their daily diets, obesity has become a major problem. The aggressive marketing techniques of fast food firms coupled with the busy urban lifestyle have significant implications for dietary health habits. The study aimed at investigating consumers’ attitudes towards fast food and the relationship between fast food consumption and obesity. The field survey design of the study employed a mixed-methods approach involving the use of a semi-structured questionnaire. The study was limited to the Mdantsane Township located in the Eastern Cape Province of South Africa. A quota sample of 200 respondents (n = 200) was selected from which data were collected using a self-administered questionnaire. Descriptive results revealed that the participants had positive attitudes towards fast foods. Although they agreed that eating fast foods increased body weight, the participants mostly did not feel overweight or obese. The participants were well aware of the negative health implications of excessive fast food consumption. This knowledge generally did not deter their positive fast food attitudes, although participants expressed their desire for additional healthier fast food options in the market. Regression estimates further revealed that carbohydrate and starchy type of fast foods (𝑃 < 0.01), other sources of fast foods (𝑃 < 0.05), age group, physical appearance and meaty type of fast foods (𝑃 < 0.10) had significant influence on the frequency of fast food consumption. The results further revealed that physical appearance (𝑃 < 0.01), religion (𝑃 < 0.05), age group and supermarkets and source of fast foods (𝑃 < 0.1) had significant influence on respondents’ BMI scores. The study concludes that there exist socio-economic and institutional factors that have considerable bearing on consumers’ fast food consumption and BMI scores. The study advocates for public health policy making concerning awareness of the negative health consequences of fast food consumption targeting mostly young adult females who mainly purchase in franchises and supermarkets with a high meaty diet.

- Description: This study examines Cuba’s role in the two southern African countries of Angola and Namibia during the Cold War period. It argues that Cuba’s ideological motivations have been embodied in the mutually reinforcing concepts of proletarian internationalism and anti-imperialism. These conceptual perspectives constitute some of the central variables that influence Cuba’s foreign policy behaviour in international relations. It is within this context that one can understand Cuba’s involvement in Southern Africa. This study also attempts to explain that Cuban foreign policy towards Africa was based on two complementary and contextual objectives namely, promoting nationalism at home and nurturing revolutionary Marxist-Leninist governments, as well as supporting anti-colonial and anti-imperialist movements abroad. For the purpose of achieving these foreign policy objectives, Cuba not only engaged in state-to-state relations with Angola and Namibia; but had cordial relations with the rest of the continent and in particular Southern Africa, which also became a direct military testing ground for Cuba’s commitment to an anti-colonial and anti-imperialist revolutionary stance. Furthermore, the thesis shows that Cuba’s relentless hatred of imperialism is rooted in its historical relationship with the United States because from the turn of the century till 1958, the Americans interfered in Cuba’s internal affairs by supporting corrupt administrations and exploited the country. These practices by the United States laid the foundation for Cuba’s anti-colonialism and antiimperialism abroad. Ultimately, this thesis shows that Cuban involvement in Angola and Namibia can be conceptualised within these contexts (anti-imperialism, anti-colonialism, proletarian internationalism and revolutionary Marxism-Leninism). The role of Cuban nationalism in the realisation of these objectives and ideals, as well as its role in perpetuating and consolidating her foreign policy is assessed in this study. This nationalism and ideals of internationalism constitutes the central idea in the Cuban revolution. Finally, this thesis asserts that Cuban motives for getting involved in the politics of Southern Africa were not motivated by economic or imperialistic reasons. Rather, the historical similarity and colonial experiences between Africa and Cuba were some of the central causal factors.

- Description: Enterococcus species are integral members of the gastrointestinal microfloral of humans, animals, birds, as well as insects. Their presence in water and food has been greatly associated with faecal contamination. This study was aimed at evaluating the incidence of Enterococcus species in cow dung and environmental water sources in three commercial dairy farms. In addition, their antibiotic profiles were determined as well as resistance and virulence genes. Furthermore, the genetic relatedness of the isolates was determined by molecular typing method (RAPD PCR). Three hundred and thirty four water and faecal samples consisting of 117, 116 and 101 were collected from Seven Star Middle Drift and Fort Hare Dairy trusts respectively. Of the 334 samples collected, 289 were of faecal origin and 45 from water sources within the farms. All samples were screened for enterococci using culture base growth media and molecular methods targeting the tuf gene. Speciation was done using species-specific primers and the incidences of various species within the farms determined. Furthermore resistance to antibiotics and multidrug-resistant phenotypes were established using the disk diffusion method. Genes coding for virulence and resistance were also determined. From the samples collected, 313 (289 faecal and 24 water) presumptive enteroccocci were isolated, 305 of 313 (97.45 percent) were confirmed as Enterococcus of which 239 of 305 (78.38 percent) were identified as E. hirae, 15 of 305 (4.92 percent) as E. faecium, 12/305 (3.93 percent) as E. durans, 6 of 305 (1.97 percent) as E. faecalis and 33 of 305 (10.82 percent) were unidentified. Out of the five virulence genes that were targeted in the study only gelE (71.80 percent of 219/305) and ace (27.2 percent 83/305) were present in the isolates. Phenotypic resistance to antibiotics was observed is in all twelve antibiotics tested with multidrug resistance phenotypes detected in some enterococcal isolates most predominant in Seven Star and Middledrift dairy trust. Finally RAPD profiles of the isolates showed high relatedness between the strains from water and cow dung sources in all three commercial dairy farms suggesting possible contamination from cow dung to the water sources or vice versa.

- Description: According to the World Health Organisation (WHO), deaths attributed to Plasmodium falciparum exceeded 584 000 in 2013, with 198 million new cases of malaria being reported. One contributing factor to these alarming figures is the emergence of drug resistance against available antimalarial agents. Therefore, there is a pressing need to develop new therapeutic antimalarial drugs with novel mechanisms of action in order to curb the increasing spread of malaria. The indole scaffold is often associated with biologically active compounds, recently exemplified by the antimalarial agent NITD609, which is currently in phase 1 clinical trials. Based on the biological evaluation of a small series of indolyl-3-amides and esters which showed moderate antimalarial activity, coupled to significant toxicity, we were prompted to investigate the synthesis of a series of indolyl-3-ethanone-α-amines (3.37 and 3.41), ethers (3.39 and 3.44) and thioethers (3.42, 3.43, 3.40, 3.45 – 3.73), where the carbonyl moiety and respective heteroatom were separated by a methine spacer. We further investigated these compounds for in vitro biological activity against P. falciparum and a human HeLa cell line. Our study explored the synthetic pathway of a three-step procedure toward our target compounds, with the initial Friedel-Crafts acetylation of indole, followed by α-bromination of the respective 3-acetylindoles. Finally, the halogen of the α-bromo ketone was substituted with an appropriate nucleophile, to yield our desired compounds. Various reagents were explored to optimise the nucleophilic displacement step, including potassium carbonate and various silver containing compounds. While many of the silver salts were found to assist in nucleophilic substitution, none were superior to the addition of potassium carbonate. The majority of compounds, chiefly the thioethers, displayed promising antimalarial activity, against the chloroquine sensitive 3D7 P. falciparum strain, with two thioethers in particular (3.54 and 3.65) inhibiting P. falciparum in the low nanomolar range. Additionally, active compounds were generally found to be non-toxic against HeLa cells, indicating that indolyl-3-thioethers are selective for the malaria parasite. These findings allowed us to begin hypothesising a structure activity relationship of this class, as well as elucidating the possible pharmacophore. In a speculative attempt to uncover the possible mechanism of action of these active compounds, in silico docking studies were conducted against Staphylococcus aureus HPPK (PDB ID: 4CRJ), which is an enzyme that immediately precedes DHPS in the microbial folate biosynthesis. Inhibition of folate biosynthesis is a validated selective antimalarial pathway and HPPK also exists in P. falciparum. Results from these docking studies suggested that our inhibitors bound well in the HPPK ATP pocket and were supportive of our hypothesized structure activity relationship.

Therefore, there is a pressing need to develop new therapeutic antimalarial drugs with novel mechanisms of action in order to curb the increasing spread of malaria. The indole scaffold is often associated with biologically active compounds, recently exemplified by the antimalarial agent NITD609, which is currently in phase 1 clinical trials. Based on the biological evaluation of a small series of indolyl-3-amides and esters which showed moderate antimalarial activity, coupled to significant toxicity, we were prompted to investigate the synthesis of a series of indolyl-3-ethanone-α-amines (3.37 and 3.41), ethers (3.39 and 3.44) and thioethers (3.42, 3.43, 3.40, 3.45 – 3.73), where the carbonyl moiety and respective heteroatom were separated by a methine spacer. We further investigated these compounds for in vitro biological activity against P. falciparum and a human HeLa cell line. Our study explored the synthetic pathway of a three-step procedure toward our target compounds, with the initial Friedel-Crafts acetylation of indole, followed by α-bromination of the respective 3-acetylindoles. Finally, the halogen of the α-bromo ketone was substituted with an appropriate nucleophile, to yield our desired compounds. Various reagents were explored to optimise the nucleophilic displacement step, including potassium carbonate and various silver containing compounds. While many of the silver salts were found to assist in nucleophilic substitution, none were superior to the addition of potassium carbonate. The majority of compounds, chiefly the thioethers, displayed promising antimalarial activity, against the chloroquine sensitive 3D7 P. falciparum strain, with two thioethers in particular (3.54 and 3.65) inhibiting P. falciparum in the low nanomolar range. Additionally, active compounds were generally found to be non-toxic against HeLa cells, indicating that indolyl-3-thioethers are selective for the malaria parasite. These findings allowed us to begin hypothesising a structure activity relationship of this class, as well as elucidating the possible pharmacophore. In a speculative attempt to uncover the possible mechanism of action of these active compounds, in silico docking studies were conducted against Staphylococcus aureus HPPK (PDB ID: 4CRJ), which is an enzyme that immediately precedes DHPS in the microbial folate biosynthesis. Inhibition of folate biosynthesis is a validated selective antimalarial pathway and HPPK also exists in P. falciparum. Results from these docking studies suggested that our inhibitors bound well in the HPPK ATP pocket and were supportive of our hypothesized structure activity relationship.

Paul and Barnabas in Lystra (Acts 14:8-20): the contextualization of the Gospel in a Graeco-Roman city

- Description: This thesis will investigate the extensive Graeco-Roman characteristics of the Lystra speech and in so doing convey some clarity in the otherwise widely differing opinions held about it. This will be achieved by showing that Lystra was a Hellenistic city of some importance with a varied population. It will be argued that the initial reaction of the Lystrians to the miraculous healing of the cripple is to be understood as representing typical Graeco-Roman notions. This will include Luke's use of a legend which not only adds local colouring to the narrative but also introduces Graeco-Roman themes such as the blurring of the distinction between humans and gods and the custom of sacrifice. This contextualization immediately portrays the Graeco-Roman nature of the Lystrians' behaviour and attitudes. In addition to these themes it will be argued that the Lystrians are shown to being reliant on secondary notions of God, which when exposed to the proclamation of the apostles will prove to be inadequate. It will also be argued that the speech of the apostles is structured in a typically Graeco-Roman rhetorical form, where the errors are first exposed before the truth is presented. In conjunction with this structure it will be argued that the philosophical concept of which Dibelius has shown to be clearly presupposed in the Areopagus speech, is not only present in the Lystra speech but forms the philosophical basis on which it is structured. This concept explains the insistence by the apostles that they are human and that God has no need of such worthless things as sacrifices. It also explains the presentation of God's activity in creation and providence as an antithesis to a god who is in need. The Graeco-Roman aspects are brought to a close with the discussion of idea that an awareness of God does not depend on secondary notions acquired from legends or customs but that the truth is grasped through a process of reflection on creation and providence. This is an important notion in the speech for it exposes the Lystrians as being in need of a reorientation of their beliefs in God, away from those which are secondary to those which are primary and compatible with the truth.

- Description: This study addresses the question of people-centred development as a transformative aspect of the new South African development arena. The concept is defined as the involvement and active participation of people in the decision-making, evaluation and implementation of the development processes, It is one of the forms of democratisation which involves the decentralisaton of authority to the lower tiers of government. This study provides an analysis of the efficacy, relevance, advantages and disadvantages of people-centred development in the South African context. The Zikhoya-Ngqinisa Woodlot Trust Project was chosen as a case study, The reason was that through the process of devolution of the Department of Forestry and Water Affairs (DWAF), which involved the handing over of the management and financial resources of the small woodlots to the communities for their own benefit, the two villages, Zikhova and Ngqinisa, were given the Zikhova woodlot. The devolution of DWAF is one of the various forms of decentralisation that has given more autonomy to the lower tiers of government in the sense that the communities now have to satisfy their own needs. The main focus of the study was to identify and analyse constraints on the implementation of people-centred development specific to the Zikhova-Ngqinisa Woodlot Trust Project. Other interrelated aspects of people-centred development such as sustainability, community involvement and benefits of the project were also investigated and analysed. , KMBT_363

- Description: From Introduction: The pine emperor moth, Nudaurelia cytherea capensis Stoll is an insect which, during the larval stage, causes extensive defoliation of the pine tree, Pinus radiata in the Cape province. These insects are susceptible to a virus disease, which on occasions causes large scale mortality. Five nonoccluded viruses have been shown to infect the pine emperor moth, and of these, one found in the greatest concentration, Nudaurelia capensis β virus (NβV) has been characterised to the greatest extent. This virus has been shown to contain RNA, to be isometric with a diameter of 36 mm, and to have a molecular weight of 16 million. The virus occurs in all stages of the insect's development, and by fluorescent antibody staining has been shown to develop in the cytoplasm of the host's cells. There have in recent years been a number of reports describing nonoccluded RNA viruses which appear to be similar to NβV. These are the viruses isolated from the moths Gonometa podocarpi and Antheraea eucalypti, and the one from the citrus red mite, Panonychus citri. These viruses have not been as extensively characterised as NβV, so the extent of the similarity between them and NβV is not known. However it would appear as if their discovery collectively heralds the emergence of a distinct new grouping within the nonoccluded RNA viruses of insects. This work reports the isolation and further characterisation of N. capensis β virus, its protein and nucleic acid.

- Description: Access to renewable energy supplies is a critical foundation for sustainable development and poverty alleviation. Anaerobic biogas-digesters also referred to as bio-digesters, have been identified as one of the leading technologies with regards to assisting in improving energy access for remote rural areas that still remain dependent upon biomass usage. This thesis assesses the potential feasibility of bio-digesters for rural households in South Africa by focusing on the experiences of a remote and rural community in Eastern Cape. A standardised survey was used to capture household details and energy use patterns of households with 180 interviews being conducted. Field observations were also conducted on the five bio-digesters installed in the community over a three month period. Despite the predominance of electrification in the community, households were heavily reliant upon biomass in the form of fuelwood and cattle dung to supplement their energy needs. Households supplemented their energy usage with alternative energy sources such as LPG gas and paraffin, especially during periods when electricity was unavailable or deemed too expensive. Initial knowledge of bio-digester technology in the community was non-existent, however with the installation of bio-digesters within the targeted villages, social learning was observed. Despite low temperatures bio-digesters continued to function throughout the study period, though malfunctions did occur and gas production did not reach optimal levels. Primary challenges encountered were the lack of financial subsidies for wide-spread adoption; the limited technical capacity of the community to conduct repairs and minimal gas production due to a build-up of ligneous materials within the gas chamber of the bio-digesters. Bio-digesters were found to provide significant benefits for households and further studies into maximising their effectiveness for rural South African households are recommended.

- Description: The focus of the study was to explore and describe reasons for poor professional behaviour among nursing students at a public nursing college in the Eastern Cape. The objectives of the study were to explore and describe the reasons for poor professional behaviour among nursing students and to describe strategies to improve poor professional behaviour. The study has significance for the college management, staff, nursing students, registered nurses and everyone involved in professional development of nursing students. The population for this study consisted of third-year nursing students following the four-year comprehensive basic course for registration leading to the Diploma in Nursing (General, Community & Psychiatry) and Midwifery at a public nursing college. The research questions were: What do you understand by professional behaviour? What are the reasons for poor professional behaviour among nursing students? What could be done to improve professionalism among college nursing students? A qualitative, explorative, descriptive and contextual design was used as a framework for the study. Permission to conduct the study was obtained from the University of Fort Hare ethics committee and other relevant authorities as indicated in the study. Ethical principles were maintained and informed consent obtained. Data collection was done using focus groups and an audiotape with a purposefully sampling of 30 third-year nursing students at the public college of nursing. Data were analysed using Tesch’s method of analysis for qualitative research. Three major themes emerged: students’ understanding of professional behaviour, reasons for poor professional behaviour and methods to improve poor professional behaviour. It was concluded that poor professional behaviour has an effect on professionalism and it should be addressed and corrected for protecting the professional image. Recommendations: Policies regarding inappropriate professional behaviour at the college should be in place and easily accessible to every staff member and nursing student. Department of Health should conduct reflective courses and seminars on professionalism and these should begin at the same time as the academic programme.

- Description: The education system in Namibia was shaped by the policies located within the framework of the apartheid ideology. Since it gained its independence in 1990, the government positioned education at the top of the national priorities. Thus, there has been a growing realisation of the importance of more democratic forms of leadership in the education system for the country to be able to cater for a democratic society. Amongst others, teachers became active creators and managers of the learning outcomes. In addition, teachers are regarded as agents of change and the driving force for productive teaching and learning. Literature describes how the management in schools has been redistributing authority and power so that a culture of teacher leadership in school communities can grow. More importantly, school improvement depends more on the active involvement of teacher leaders as it is realised that people in formal positions cannot do everything. In this line this study investigated the understanding of teachers and members of management of teacher leadership practice and it further identified the structural and cultural factors which enabled and inhibited this practice in a primary school. This study is a case study of a Primary school in a semi-urban area of Otjozondjupa Region, a central part of Namibia. This study was conducted in the interpretive paradigm and it is a qualitative case in nature, employing semi-structured interviews, observation and document analysis. Triangulation over the data revealed that respondents have an understanding of the concept and that all teachers are involved in leadership roles at school which are more strongly found in the classroom and through involvement with other teachers. Teacher leadership roles at the case study school also occur within the whole school with some limitations and also extend beyond the school. Grant’s (2008) model of teacher leadership was used to analyse the data. The study suggested some hindrances and supporting factors of teacher leadership. The findings suggested that teacher leadership is understood at the case study school and that they experienced factors that enabled and hindered this practice at different stages. Enabling factors included the school structure, further studies and workshops attended, while teacher leadership is impeded by teachers’ unwillingness to collaborate with others and the platoon system. The study recommends future large scale studies, including at secondary schools, so that a broader sense of teacher leadership may emerge.

The findings suggested that teacher leadership is understood at the case study school and that they experienced factors that enabled and hindered this practice at different stages. Enabling factors included the school structure, further studies and workshops attended, while teacher leadership is impeded by teachers’ unwillingness to collaborate with others and the platoon system. The study recommends future large scale studies, including at secondary schools, so that a broader sense of teacher leadership may emerge.

- Description: This treatise is the result of an initial interest in the concept of ‘terrain vague’, the phenomenon of disconnected spaces that are internal to the city yet exist outside the effective and functioning networks of the urban system (Sola-Morales 1995, 120). The notion of terrain vague informs the theoretical preoccupation of this study and sets the basis on which the contextual and programmatic concerns are considered and explored. The harbour precinct of Port Elizabeth was selected as the focus area for the study, in which the characteristics of the terrain vague were uncovered through a series of maps, diagrams and photographs. The role of the cemetery as a type of terrain vague in the urban fabric is simultanelously investigated. The study refers to Richard Weller’s interpretation of the nature of the contemporary city and principles of landscape urbanism as a basis for developing ways of approaching the city and it’s spaces of terrain vague.Through this, the study is situated predominantly in the ecological discourse. The use of precedant studies as a means of exploring the application of the theoretical principles discussed in this study is key to providing the reader with a contextual understanding and clarity. The architectural intervention proposes a memorial park in the harbour precinct. This aims to generate a spatial awakening of the terrian vague. By reclaiming the denatured landscape (oil tank farm) and re-scripting it as a culturally significant area that is re-integrated into the public realm, the opportunity to rehabilitate the ecological flows of the city is realised. The design of a promatorium complex within the proposed memorial Park aims to re-introduce the funerary landscape into the city and in doing so challenges the threat of cemetries remaining as spaces of terrain vague. The promatorium complex is seen as a facility that supports the functions of the memorial park as a commemorative landscape in the 21st century. In all this intervention aims to transform a disregarded wasteland into an operational landscape. The aim is to enhance the ecological systems of the city and by extension to reconcile the interface between man and nature.
