- Description: ICT integration in secondary schools in Sub-Saharan Africa is still at an early stage and already faces several setbacks that may undermine the various initiatives undertaken by governments and the private sector to promote the use of computers in schools. Based on literature and other research, this may be attributed to the fact that no guidelines for proper ICT adoption in secondary schools exist; and furthermore, most integration cases were done haphazardly with no systematic approach based on the existing frameworks or tailored towards the real context in the schools concerned. The present study aimed to provide guidelines for the successful integration of ICT into schools in Cameroon. A review of some existing frameworks for ICT integrations in schools, as well as the innovative pathways that some developing countries have taken to ensure the successful integration of ICT into schools were explored through a literature review, revealing the trends and challenges of ICT integration in schools in Sub-Saharan Africa. The current status of ICT in schools in Cameroon being at an introductory stage was established from the available literature. This led to the use of a single case study from the Western Region of Cameroon, where four secondary schools were selected from the most advanced schools in terms of ICT integration. Participants consisting of principals, ICT co-ordinators, teachers, and students were interviewed, in order to establish the current status of ICT in each school, as well as those factors affecting or promoting the adoption of ICT. Teachers’ and students’ surveys, as well as existing documentation were used to triangulate the data gathered from interviews with school principals and ICT co-ordinators. Data were descriptively analysed – and the findings revealed that ICT is at the introductory stage of integration in the Fluck’s Model of ICT development in schools. At school level, the lack of infrastructure and an ICT adoption plan were found to be the key opposing factors to ICT integration, whereas several enablers were identified, such as the positive attitude of teachers towards ICT, the existence of a minimum recurring budget for ICT adoption through parents’ funding, as well as the continually decreasing cost of ICT infrastructure in the market. Based on the findings and experiences from successfully proven projects, a set of guidelines were derived for schools’ decision-makers. It is critical to put in place a well-structured policy for ICT in the school and to recognise all the ICT-related costs.

- Description: This thesis raises and explores questions concerning the popularity of the Homeric poems in ancient Greece. It asks why the Iliad and Odyssey held such continuing appeal among the Greeks of the Archaic and Classical age. Cultural products such as poetry cannot be separated from the sociopolitical conditions in which and for which they were originally composed and received. Working on the basis that the extent of Homer’s appeal was inspired and sustained by the peculiar and determining historical circumstances, I set out to explore the relation of the social, political and ethical conditions and values of Archaic and Classical Greece to those portrayed in the Homeric poems. The Greeks, at the time during which Homer was composing his poems, had begun to establish a new form of social organisation: the polis. By examining historical, literary and philosophical texts from the Archaic and Classical age, I explore the manner in which Greek society attempted to reorganise and reconstitute itself in a different way, developing original modes of social and political activity which the new needs and goals of their new social reality demanded. I then turn to examine Homer’s treatment of and response to this social context, and explore the various ways in which Homer was able to reinterpret and reinvent the inherited stories of adventure and warfare in order to compose poetry that not only looks back to the highly centralised and bureaucratic society of the Mycenaean world, but also looks forward, insistently so, to the urban reality of the present. I argue that Homer’s conflation of a remembered mythical age with the contemporary conditions and values of Archaic and Classical Greece aroused in his audiences a new perception and understanding of human existence in the altered sociopolitical conditions of the polis and, in so doing, ultimately contributed to the development of new ideas on the manner in which the Greeks could best live together in their new social world.

- Description:
Animals that inhabit unfavourable habitats and experience seasons where the cost of maintenance exceeds the available energy resources have over time developed behavioural and physiological mechanisms to survive. These adaptations include changes in activity, improvement of cold tolerance by using nonshivering thermogenesis (NST), improvement of thermal conductance, reduction of body mass, or acclimation to colder temperatures (reduction of metabolic requirement). In addition some species exhibit heterothermy, in the form of either daily torpor or longer-term hibernation. The southern African hedgehog (Atelerix frontalis) is an excellent candidate to investigate the phenomenon of heterothermy because it is a small insectivore (summer body mass ca. 300 to 400g), burrows, inhabits harsh habitats and is not easy to find during the winter months. In this study I aimed to investigate whether A. frontalis exhibits seasonal differences in metabolic rate and furthermore if this species exhibits heterothermy. The study was carried out in the Northern Cape Province, South Africa. Hedgehogs were hand captured and their metabolic rates were measured using indirect calorimetry. Individuals were implanted with temperature dataloggers for a summer period (November 2009-January 2010) and a winter period (May-August 2009). The summer BMR of adult A. frontalis (0.448 ±0.035 mlO2/g/h, n=4) was significantly lower than their winter BMR (0.811 ±0.073 mlO2/g/h, n=4) and statistical analyses revealed that this was an affect caused by seasonal changes in the ambient environment. Individuals spent up to 84 percent of time during the measurement period torpid (-8°C

- Description: Despite the acknowledged reality that HIV-related stigma is a major barrier to effective HIV prevention and treatment, and perhaps because it is complex in nature, few local empirical scales have been developed to measure stigma and to be able evaluate the impact of anti-stigma interventions. Whilst the development of two recent South African HIV-related stigma scales can be celebrated as a major breakthrough, the reliability and validity of these scales across contexts remains largely unknown. This research project employs these two local, and competing, HIV-related personal stigma scales - the first developed by Kalichman et al. (2005) and the second developed by Visser, Kershaw, Makin and Forsyth (2008)-to compare the psychometric properties of the scales and to obtain a measure of HIV-related stigma with a sample of 246 service staff employed at either Rhodes University Catering Division or the Hi-Tec Security company, both organisations located in Grahamstown, a small town in the Eastern Cape, South Africa. Both organisations are major employers of semi-skilled workers in this local context. The results suggest that the Visser et al. scale (2008) reports slightly better psychometric properties than the Kalichman et al. (2005) scale for this sample. Furthermore, the security guards appear to be more stigmatising than the caterers, and it is suggested that this might be a consequence of the combined influences of normative occupational roles and workplace context. Results also show that participants who practices safe sex, know someone with HIV and/or who have been tested for HIV show lower levels of HIV-related stigma. Finally, personal stigma scores are generally lower than attributed stigma scores, which might offer a useful point of intervention.

- Description: Providing adequate sanitation facilities for the poor remains one of the major challenges in all developing countries. In South Africa, an estimated 11,7% of the schools are without sanitation. The South African government has a constitutional responsibility to ensure that all South Africans have access to adequate sanitation. When sanitation systems fail, or are inadequate, the impact of the health of the community, on the health of others and the negative impact on the environment can be extremely serious. In rural South African schools, many Enviro-Ioo toilets are available today. They are designed to suit a variety of water scarce areas and where there is a high risk of contamination of ground water resources. It is important to realize that any Enviro-Ioo system programme requires an education programme to ensure that the principles of use and maintenance are clearly understood by the user group. Their maintenance requires more responsibility and commitment by users. This study is an interpretive case study that indicates how sanitation in a rural Ramashobohle High School in Polokwane municipality was managed through an EcoSchools Sanitation Community of Practice, and how this developed action competence for sanitation management in the school. The study established that the earlier practice and knowledge of the Ramashobohle Eco-Schools community of practice exercised in maintaining Enviro-Ioo systems was inadequate; unhealthy and unsafe according to the data generated through focus group interviews, observations, interviews, action plan, workshops and reflection interviews. The data generated also indicates that the Eco-Schools community of practice was not committed to maintaining sanitation in their school because they were not sharing sanitation knowledge; they were not communicating and not updating one another concerning Enviro-Ioo systems maintenance as they had no adequate knowledge as to how to maintain the facilities; and the school management was also not supportive and was not taking responsibility. The study shows how this situation was turned around as an Eco-Schools Sanitation Community of Practice focussed on developing action competence in the school community. It provides a case based example of how knowledge and action competence, supported by an Eco-Schools Community of Practice, can find and implement solutions to inadequate sanitation management practices in rural schools, and shows how members of the school community can be engaged in learning how to manage and maintain school sanitation systems through a participatory process that develops action competence. The study points to important dimensions of developing action competence, such as providing knowledge and demonstrations, inviting experts to the school, involving learners in observations and monitoring and in ensuring that adequate facilities are available. In particular, a workshop conducted by Enviro-Ioo consultants, organised and supported by the Eco-Schools Sanitation COP, together with a follow up action plan, provided the main impetus for changes in practice in the school and served to support action competence development. Finally the study provides research findings and recommendations for further research.

- Description: The research seeks to evaluate how the South African government has conceptualised gender through the use of the concepts of WID and GAD. This research has been conducted through the analysis of the Draft Strategic Framework on Gender and Women's Empowerment a document of the Department of Trade and Industry that was formulated to address and redress the issues of gender equality. It has some sound suggestions that seek to identify strategies to improve women empowerment through financial independence. As a result they have used various approaches in order to provide strategies that are mindful of the „needs‟ of the women. Accordingly they have formulated a policy that understands who these women are and have made recommendations of strategies that different groups of women can identify with. They have included the marginalised rural and disabled women and even gone as far as catering for younger women still at school. However there has been concern at the impact that the exclusion of men has contributed, therefore it is important to find ways in which to make men more involved.

- Description: Stock market linkages have implications for portfolio diversification, asset pricing, monetary and regulatory policy as well as financial stability. This study examines the extent to which African stock markets are linked using daily data for the period 2000-2010. The study is divided into three main parts each focussing on the ways in which integration of the stock markets can be viewed. Firstly, we analyse the long run co-movement of the stock markets using both bivariate and multivariate Johansen (1988) and Johansen and Juselius (1990) cointegration approaches. Secondly, we analyse returns linkages using Factor analysis and the Vector Autoregressive (VAR) models. In the Factor Analysis model, we used two extraction methods, namely Principal Component Analysis and the Maximurn Likelihood technique. The VAR model was extended with impulse response, variance decomposition and block exogeniety. Thirdly, we analyse the behaviour of volatility and the volatility linkages among the stock markets. We initially analysed and modelled volatility in each stock market using the GARCH, EGARCH and GJR GARCH and then examined the long-term trend of the volatility. Conditional volatility series for each country were then estimated using the most appropriate model and were analysed using VAR, block exogeniety, impulse response and variance decomposition to determine the extent of their linkages. The findings of the study are as follows: Both the bivariate and multivariate models found slim evidence of cointegration amongst the stock markets, suggesting that there were opportunities for portfolio diversification for investors. In general, the financial crisis had very little impact on the long-run relationships of the stock markets. Results for the returns linkages showed that there were limited retums linkages with the exceptions of South African-Namibia and Egypt-Morocco to a lesser extent. South Africa was found to be the most endogenous, whilst Ghana and Nigeria were the most exogenous on the continent. We regards to volatility, we found that it was asymmetric and persistent across all the stock markets with long term trend of volatility showing that it significantly increased for most of the markets. Finally, there were limited volatility linkages, only between South Africa, Egypt and Namibia, implying that African stock markets are still largely segmented from each other. However, the linkages between South Africa and Egypt could have negative effects as they could lead to the spread of contagion effects during times of crises. Therefore, policymakers should consider revising and improving policies to enhance economic integration on the continent.

- Description: Research suggests that there is a relationship between religion and business ethics. When looking at the South African society and the statistics that says that 80 percent of the population is Christian but on the other hand we are confronted within this country with increasing incidents of corruption in private companies as well as in public services. Why would that be the case? This study seeks to understand if Christianity or the local church really makes an impact on the lives of its members. The research starts of by looking at behaviour in general and what constitute to good ethical decision-making. In the study on Christian ethics it becomes clear that there is a strong appeal in the Bible on ethical behaviour. The Bible goes as far as to claim that, when in a relationship with the Lord, the followers will show His character in the way they live at home and the way they behave and make ethical decisions at the workplace. This study used focus groups to research the role of the local church in changing behaviour. The study finds that Christianity per se does not change the behaviour of church members. The church members‘ definition of the church largely determines the impact the church will have on their lives. In the study on the Christian ethics it was clear that ethics were seen as something that was formed in communities and not by rules or regulations. It was not a case of people telling others what to do and what not. It was more a case of mentors that helped others to live differently in community with others. The study finds that when the local church is build on relationships and if there is a strong sense of community, the church has a huge impact on the lives of its members. This suggests that the local church should be more focused on strong and intimate relationships and not so much on the church as organisation or institute. This is also important for the businesses that will employ these members because they will make better ethical decisions.

- Description: This quantitative exploratory-descriptive study investigated the value of human figure drawing (HFD) tests for developmental testing in the South African context. Due to their characteristics such tests may be particularly suitable to screen for developmental delays in the local South African context. The objectives of the research were to explore and describe the standardized HFD scores and Griffiths Mental Development Scales – Extended Revised (GMDS-ER) general quotients (GQ) of the sample; to investigate whether a relationship exists between the standardized HFD scores and GQs; and to investigate the strength and directionality of this relationship if it was found to exist in the sample. Relevant literature was discussed and an integration of key constructs was provided. The research sample consisted of 30 GMDS-ER protocols collected at a University Psychology Clinic in the Nelson Mandela metropol, Eastern Cape, South Africa. The HFDs of the Draw-a-person items of the GMDS-ER protocols were scored according to the scoring criteria of the Draw-a-Person Intellectual Ability Test for Children, Adolescents, and Adults (DAP: IQ). Key findings included the following: a statistically significant large positive correlation indicative of a marked relationship existed between standardized HFD scores and GQs. The DAP: IQ might provide a better indication of mental development than intellectual ability. A statistically significant medium positive correlation indicative of a small but definite relationship existed between chronological age and HFD raw scores. In conclusion, the findings suggest that HFDs follow a developmental progression and that HFD tests may be useful in developmental testing.

- Description: Human trafficking has been reported to be on the increase in the Eastern Cape Province of South Africa with girls as young as ten years old being trafficked from and within the Province for sexual and labour purposes, and marriage. Human traffickers operate in rural areas, small towns and cities such as Port Elizabeth and East London. However, research on the role of the law enforcement authorities and the civil society organisations in the fight against trafficking in Eastern Cape Province is largely unknown. Situated within the Security Governance Theory, and using the intensive research design, this research reports on the role of the law enforcement authorities and the civil society organisations in the fight against human trafficking in Eastern Cape Province with emphasis on rural-urban differentiation. The challenges which law enforcement authorities and the civil society organisations faced are also discussed. The study, among other things, found that both the law enforcement sector and civil society organisations in the Province ensured that security, criminal justice, physical, emotional, psychological, health and spiritual needs of rescued victims of trafficking were met. The study further established that there was little progress in the fight against human trafficking, more especially in the rural areas of the Province, due to inadequate cooperation among anti-trafficking organisations and the lack of resources.

- Description: The electrolysis of water was evaluated as a potentially efficient, as a low cost means of hydrogen production. The theoretical energy, voltage, current, and energy efficiencies of water electrolysis were considered by using various catalyst materials used in the fabrication of membrane electrode assemblies used in low temperature water electrolysis systems. Traditionally, iridium based catalysts have shown to be the most suitable material for its use on electrocatalysis of water to form hydrogen. This study showed that a combination of various elements as a binary and or ternary mixture in the base catalyst that was applied to the anode and cathode by using the Adam’s method had shown to give comparatively good results to that of using iridium oxide on its own. These catalysts were characterized by cyclic voltammetry, at different temperatures (30oC-80oC) with a range of catalyst loading of 0.2-0.5 mg.cm-2 noble metals. The study showed that the Ir40Co40 mixture as an anode catalyst was found to show highest hydrogen efficiency of 73 percent with a relatively low over potential of 0.925V at higher temperature of 80oC. The mixture also showed to give the best electrocatalytic activity with a low Tafel slope of 30.1mV.dec-1. Whereas the Ir50Pt50 showed a comparatively lower hydrogen efficiency of 65 percent with a lower over potential of 0.6V at 50oC. Ternary mixed oxide of Ir20Ru40Co40 showed an even lower over potential of 0.5- 0.6V over a large range of temperatures with a low hydrogen efficiency of 44 percent but gave good electrocatalytic activity in terms of the Tafel slope analysis. On the other hand, mixtures with relatively cheaper material such as Nickel in binary mixture systems such as Pt50Ni50 as cathode catalyst was found to show promising performance of a relatively low over potential that was less than 1.4 V with a low hydrogen efficiency of 62.1 percent Ternary cathode catalyst materials such as Pt33Ni33Co33 exhibited good performance with higher hydrogen efficiency of 65.2 percent at lower over potential of 1.2 V and a higher Tafel slope of 133.9 mV.dec-1 at 80 0C.

- Description: The hydrology of the Kudumela Wetland, Limpopo Province of South Africa was studied from November 2005 to April 2007, involving both fieldwork and laboratory analyses. This study presents the results of an investigation of the hydrology of the Kudumela Wetland in South Africa, and its contribution to dry season flow in the Mohlapitsi and Olifants Rivers. Initially, 40 Piezometers were installed along seven transects and water levels monitored in order to understand water table level characteristics (fluctuations) with time. Water levels in transects one, three, the right bank portion of transect four and transect six showed fluctuations. Transect two, the left bank portion of transect four and transect five did not show significant temporal changes. The relationships between piezometer water levels, rainfall in the study area and stream flow observed at a river gauging station are not clear. The river within the wetland is a gaining stream because the water table level elevation is above that of the river. This indicates that the wetland is feeding the river. The northern part of the wetland (T1 and T2) is affected by artificial drains and most of the piezometers closest to the river channel showed the lowest variations. The relationships between rainfall, groundwater, and surface water at this site shows that stream flow did not respond quickly to precipitation as expected, even in months when rainfall increased (for example, 74 and 103mm during 08/02/06 and 18/02/06 respectively), and the groundwater levels did not show fluctuations, indicating that groundwater responds gradually to precipitation, and that the relationship between rainfall, groundwater and surface water is complex. The environmental stable isotopes (deuterium and oxygen-18) and the radioactive isotope (tritium) were analyzed, along with field observations of electrical conductivity (EC), pH, total alkalinity (Talka) and some major and minor dissolved ion analyses for tracing water dynamics in the study area. A total of 39 water samples was taken and analyzed from boreholes, auger holes, right bank and left bank drains, various points along the river and springs in four sampling visits to the wetland. The results did not clearly provide a temporal record of isotope and chemical variations in the various sources. Results from the most extensive sampling survey in April 2007 provide the most comprehensive overview of hydrological relationships. Clustering of the stable isotope data suggests that the water samples of upstream and downstream river, auger holes further south and most drains clustered together suggesting a common water source and almost all samples fall above the global (GMWL) and local (Pretoria MWL) meteoric water lines, while some fall between the global and Pretoria meteoric water lines. Six representative water samples were analyzed for major ion concentration. Both cation (Ca, Mg, K, and Na) and anion (HCO3, SO4, Cl, and NO3) analyses in November 2007 confirmed conclusions reached from field observations. The analysis shows that a single type of water (Ca, Mg-HCO3) is involved in the study area. In almost all major ion plots, the right bank drains, upstream river and downstream river samples grouped together in a single cluster. As the means for reliable river flow measurements were not available, except for the gauging station at the outlet of the valley, rough, semi-quantitative estimates were made during several field visits. These, suggest considerable losses of river flow into the gravel/boulder beds at and below a gabion dam at the head of the valley. Three major and several other left bank springs and right bank drains at transects T1 and T2 contributed to the river flow at all times. Along with the isotopic and chemical evidence, these observations have lead to a hypothesis that river water enters the wetland and flows back to the Mohlapitsi River through boulder beds underlying the wetland and through drains on the surface of the argillaceous aquitard covering the more conductive boulder beds. Deeper dolomitic groundwater does not appear to contribute to the water balance at least in the northern half of the wetland. Although environmental isotope and hydrochemistry results may not unequivocally prove this hypothesis they do not contradict it.

- Description: This study estimates the interdependence between South Africa‟s monetary policy and stock market performance, utilising structural vector autoregression (SVAR) methodology. The study finds that a stock price shock which decrease stock prices by 100 basis points leads to 5 basis points decrease in interbank rate. A monetary policy shock that increases the interbank rate by l percent leads to decrease in real stock prices by 1 percent. This result for South Africa is similar to the result by Bjornland and Leteimo (2009) which earlier concluded that there was a high interdependence between interest rate setting and stock prices. However the magnitude of the relationship is relatively lower for South Africa compared to that of the United States of America (USA). The result of the current study is also very much consistent with the argument that the South African stock market is resource-based and so is influenced by external shocks, meaning monetary policy shock does not have as much impact on stock market in South Africa as in the USA. However the SARB may have to consider watching movements in stock prices so that booms in stock markets do not defeat central bank monetary policy thrusts. The stock price market is an essential source of information for monetary policy in South Africa.

- Description: This present study investigated South African Afrikaans-, English- and Xhosa-speaking male and female urban secondary school adolescents‟ (N = 1301) perception of the relative importance of identity-related domains by investigating the choices that they carried out in relation to meaningful identity-related areas of their lives. Consequently a structured questionnaire consisting of 14 domain particular areas was used. In Eriksonian terms, one could say that the South African society is in a psychosocial crisis. Almost all the domain-specific items were regarded as relevant “Very important” or “Fairly important” by a notable or significant majority of participants. All fourteen of the domains were regarded as “Very important” by at least 35 percent of the participants from two cultural groups, namely African and Coloured sub cultural groups; while twelve of the domains were regarded as “Very important” by at least 50 percent of the African subgroup and thirteen domains were regarded as “Very important” by 40 percent of the Coloured subgroup. “Leisure and recreational activities”, “Friendships with members of the same sex peer group”, “My political views and convictions” and “Friendships with members of the opposite sex peer group” were however, still regarded as “Fairly important” by 56 percent, 53 percent, 58 percent and 52 percent of the total research group respectively. It should also be noted that generally females in the sample were more inclined to evaluate domains that had a bearing on interpersonal relationships as significantly more important than the males namely: Friendship with members of the same-sex peer group, What kind of person I want a permanent relationship with, What kind of person I want to marry, and How I should act as husband or wife. The males tended to evaluate the domains, Sexual matters and Friendship with members of the opposite sex more significantly important than the females did.

- Description: This thesis explores the thematic desire to establish an ecological human bond with nature in four contemporary novels: The English Patient by Michael Ondaatje, The Hungry Tide by Amitav Ghosh, An Imaginary Life by David Malouf, and The Expedition to The Baobab Tree by Wilma Stockenström. These authors share a concern with the influence that language has on human perception, and one of the most significant ways they attempt to connect with the natural world is through somehow escaping, or transcending, what they perceive to be the divisive tendencies of language. They all suggest that human perception is not steered entirely by a disembodied mind, which constructs reality through linguistic and cultural lenses, but is equally influenced by physical circumstances and embodied experiences. They explore the potential of corporeal reciprocity and empathy as that which enables understanding across cultural barriers, and a sense of ecologically intertwined kinship with nature. They all struggle to reconcile their awareness of the potential danger of relating to nature exclusively through language, with a desire to speak for the natural world in literature. I have examined whether they succeed in doing so, or whether they contradict their thematic suspicion of language with their literary medium. I have prioritised a close ecocritical reading of the novels and loosely situated the authors’ approach to nature and language within the broad theoretical frameworks of radical ecology, structuralism and poststructuralism. I suggest that these novels are best analysed in the context of an ecocritical mediation between poststructuralist conceptions of nature as inaccessible cultural construct, and the naïve conception of unmediated, pre-reflective interaction with the natural world. I draw especially on the phenomenological theories of Maurice Merleau-Ponty, whose insistence that perception is always both embodied and culturally mediated truly renders culture and nature irreducible, intertwined categories. By challenging historical dualisms like mind/body and culture/nature, the selected novels suggest a more fluid and discursive understanding of the perceived conflict between language and nature, whilst problematizing the perception of language as merely a cultural artefact. Moreover, they are examples of the kind of literature that has the potential to positively influence our human conception of nature, and adapt us better to our ecological context on a planet struggling for survival.

- Description: Training is widely conducted in organizations and is actively encouraged by the recent legislation in South Africa. Millions of Rands are spent building human resource capabilities. Organizations therefore need to know whether this investment in training is bearing fruit in terms of changes in individual performance and overall impact on service delivery. The need to improve Transversal Training Management Agency (TTMA) training programmes and skills development impact to government departments has triggered the survey. Three interdependent themes are explored: training evaluation in `government departments, influence of non-training factors and human dynamics between stakeholders in the training evaluation process. Structured questionnaires, based on best practises in literature were administered to key stakeholders involved in TTMA training programmes. Training managers and the Office of the Premier (OTP) Human Resource Development (HRD) officials were interviewed, while supervisors, trainees and trainers verified the data by post. Data were collected from the Department of Basic Education, Eastern Cape (EC), TTMA trainers and trainees. Findings show that The Department of Basic Education in the EC does not fully follow a system’s approach. Evaluations done during classroom sessions focus mainly on the reaction of participants to training and not on the behaviour change in the workplace. Training participants are not prepared for training; sometimes they do not even know why they attend training. Some trainees go to training just to get certificates that increase their CV’s for promotion purposes or to run away from the stressful work environment and not for individual growth. Recommendations to use a systemic evaluation approach and involvement of trainees in their career development process are made. Further research is recommended on the managing of non-training factors that impede learning transfer.

- Description: The application of internet marketing techniques has been widespread in the hospitality sector worldwide, with many hotels crafting websites for marketing purposes. However, there is still a debate and speculation on the impact of internet marketing on business performance and profitability. Given the well-recognised value of internet marketing in the hospitality and tourism industry, this study sought to examine the impact of internet marketing on the profitability of the hospitality sector in South Africa and to establish factors which influence internet marketing usage. In order to achieve these objectives, a perceptual survey was conducted in graded hotels and lodges in the Eastern Cape province of South Africa. Multiple linear regression analysis and hierarchical regression analysis were used to determine the relationship between internet marketing and business profitability as well as the relationship between organisational and environmental factors and internet marketing usage. Based on the findings of this study, it is concluded that the use of internet marketing can positively influence business profitability. It is also concluded that internet marketing experience moderates the relationship between internet marketing usage and business profitability. The results also indicate that factors such as technological competence, managerial support, level of star grading and alliances significantly influence internet marketing usage. Thus, from the findings of this study, it was concluded that hotels and lodges can enhance their profitability through internet marketing usage.

- Description: The social problems that exist within South Africa cannot be ignored. The magnitude of poverty, unemployment and crime that exist are ever increasing while HIV/Aids has left 10 percent of the children within this country orphaned. Discrepancies in the access to proper healthcare and education between the private sector and the public sector is evident, mainly due to the failure of the public sector (government) to effectively implement and manage the healthcare and education systems in South Africa. In the last decade, there has been a significant increase in the number of registered non-profit organisations which can be attributed to a greater awareness of the social problems that exist, as well as the inability of the government and the public sector to address the social problems on their own. Social entrepreneurs are attempting to find innovative solutions to these problems by starting non-profit organisations and then implementing projects and programmes that will help alleviate these social problems. Social entrepreneurship is a fairly new concept, particularly within the realm of academic research. Previous studies on social entrepreneurship have highlighted the need for social entrepreneurs and have also emphasised the many challenges these social entrepreneurs face, one of which is the lack of education and business skills training. Research indicates that a non-profit organisation should be run like a small business in order to be successful, which highlights the importance for social entrepreneurs to be equipped with the appropriate business skills. The impact that a social entrepreneur’s education and business skills training has on the success of a non-profit organisation is however still largely unknown. The purpose of this study was three-fold: firstly, to study the relationship between the education and business skills training of a social entrepreneur and the successful functioning of their non-profit organisations; secondly, to develop recommendations for social entrepreneurs on how to more effectively manage their non-profit organisations and guide them in what business training will benefit them as a social entrepreneur; and lastly, to add to the already existing knowledge on social entrepreneurs, particularly within a South African context. The main research methodology used to conduct the empirical investigation in this study was qualitative in nature. Elements of quantitative data collection were adopted in the instruments in order to ensure standardisation when measuring a social entrepreneur’s education and business skills training, as well as the success of their respective non-profit organisation. In-depth interviews were conducted with fourteen social entrepreneurs who work in a variety of social developmental sectors within South Africa. An interview guide was developed to record the formal levels of education and business skills training received by the respondents and to discuss the impact of other types of education and business skills training on their capabilities as managers of non-profit organisations. A tool was developed to measure the success of the respective non-profit organisations and the results were compared to the social entrepreneur’s levels of education and business skills training. Global analysis was the data analysis technique adopted in this study and was used to identify common themes among the transcripts as well as possible relationships between different variables. There were two main findings with regard to the impact a social entrepreneur’s education and business skills training has on the successful functioning of his/her respective non-profit organisation. Firstly, the formal types of education and business skills training of a social entrepreneur have a direct impact on the success of a nonprofit organisation. Secondly, once a social entrepreneur has completed school level education, informal types of education and business skills training play a bigger role than formal types in the effective management and success of his/her respective non-profit organisation. The findings of the empirical investigation showed that the most valuable three types of informal education and business skills training include workshops and conferences, business experience and networks. The most important recommendation for social entrepreneurs is that their school level education should be completed, in order to access further education and business skills training opportunities. The social entrepreneurs must equip themselves with certain skills and knowledge, namely: financial management, legal knowledge, human resource management, strategic management, monitoring and evaluation skills, technical skills and research skills, in order to ensure the successful functioning of their respective non-profit organization.

- Description: The purpose of the present thesis is to show that hyperspectral data can be used for discrimination between different tree species. The data set used in this study contains the hyperspectral measurements of leaves of seven savannah tree species. The data is high-dimensional and shows large within-class variability combined with small between-class variability which makes discrimination between the classes challenging. We employ two classification methods: G-nearest neighbour and feed-forward neural networks. For both methods, direct 7-class prediction results in high misclassification rates. However, binary classification works better. We constructed binary classifiers for all possible binary classification problems and combine them with Error Correcting Output Codes. We show especially that the use of 1-nearest neighbour binary classifiers results in no improvement compared to a direct 1-nearest neighbour 7-class predictor. In contrast to this negative result, the use of neural networks binary classifiers improves accuracy by 10% compared to a direct neural networks 7-class predictor, and error rates become acceptable. This can be further improved by choosing only suitable binary classifiers for combination.

- Description: Good governance is a critical element to economic development both at the local and national level. Devolution, which is a form of decentralization, is a means of achieving good governance if implemented appropriately. Government plays a pivotal role in the governance framework of a country. This study aimed at exploring how governance of Nairobi City can be improved under a devolved system of government to foster economic development. The study specifically looked at government effectiveness which is one of the Worldwide Governance Indicators. Through a literature review, the study looks at how devolution can improve governance, and what government effectiveness entails, not only from the World Bank perspective but also from other related literature. The major assumption of this study is that improved governance consequently leads to enhanced economic development, as argued by numerous scholars and practitioners in previous studies (Todaro and Smith, (2009) Mcneil and Malena, (2010) and UNDESA 2007). Furthermore, this study assumed that despite only focusing on one of the six indicators, an idea of good governance as a whole will be obtained. The study used a mix of qualitative and quantitative approach of a case study of Nairobi City. Nairobi City is not only a unit of devolution under the new constitution, but will also host the national government. Furthermore, it is also the financial stronghold of the country. Data was collected from two sets of respondents using two different instruments. A questionnaire was used to collect data from the citizenry, and face to face interviews were used to collect data from government officials. The questionnaire focused on capturing citizen perceptions on government effectiveness. Respondents were selected through convenient sampling at pre-determined service delivery points within Nairobi City. The face-to-face semi-structured interview gauged the level of government effectiveness of selected government institutions within Nairobi City. For the former instrument, the data was analyzed through SPSS and Microsoft Excel; and presented in tables, charts and graphs. For the latter, a descriptive discussion has been used to illustrate findings. The study found that government institutions within Nairobi to an extent have established mechanisms and systems to improve service delivery, and consequently promote government effectiveness. It is observable from the study that, the systems in place do not respond to the citizen needs and expectations as illustrated by a satisfaction index of 54 percent.
