  • Description: A fundamental idea of this study was that the formal financial institutions have an essential role to play in the process of assisting financial inclusion of South Africa's low income and under-banked consumers. Financial inclusion is important for consumers to have access to affordable basic financial products and services. An increase in the number of financially included consumers is important for growth of home ownership, positive savings habits among low income consumers and mitigating risks with insurance products. Consumers have access to financial products and services but are not equipped with the basic knowledge to fully benefit from the use of these financial products and services. As a result, the construct of financial inclusion and the measures being taken by South African financial institutions to optimise financial inclusion was investigated in this study. There is a broad consensus that under-banked consumers face a myriad of factors that may prevent them from having effective access and usage of banking products and services. The effective usage of banking products and services not only promotes an inclusive society but also consumers' ability to take full advantage of the benefits of having access to suitable financial products and services. The influence of these factors on the usage of banking products and services by low income and under-banked consumers was under investigation in this research study. The influence of these factors on the usage of banking products and services by low income and under-banked consumers was under investigation in this research study. To achieve this, the researcher identified a number of factors that have a relationship with usage. These include Financial Awareness, Trust, Fees, Simplicity and Appropriateness of banking products and services. Consumers' usage of banking products and services were tested using primary data collected from low income and under-banked consumers in the NMB. This study only focused on five influencing factors. The investigation of other possible factors contributing to the usage of banking products and services is necessary. Making use of a larger sample and an improved model with other pertinent influencing factors might bring to light the significant factors involved in the decisions made by consumers in the usage of banking products and services. The significant factors presented in this study reveals that of the five proposed relationships, only two were found to be significant (Financial Awareness and Appropriateness). The findings of the study show that the usage of banking products and services can be increased through increased Financial Awareness about various available banking products and services, changing the unrealised need of the consumers into a realised need for banking and providing affordable products and services for various sections of the population. Appropriateness also reported a positive significant influence on Usage. This means that consumers are likely to access their bank account at different locations. With banking institutions offering products and services that meet their needs, consumers can achieve their financial goals and improve lifestyles by doing all transactions via the bank account and having more control over their personal financial affairs. Recommendations where suggested based on the empirical results to help improve the banking institutions ways of attracting and retaining consumers to effectively use their products and services. It was recommended that banking institutions should tailor their marketing campaigns towards low income and under-banked consumers in order to improve the level of financial awareness of consumers about banking products and services they consume. Seek to improve their communications strategies by adopting techniques that effectively transmits their ideas between the banking institutions and low income and under-banked consumers. And also focus should be on the creation of innovative design systems to ensure that banking products and services will effectively address the needs of low income and under-banked consumers.

  • Description: The purpose of this study was to investigate the factors contributing towards the decline of learners in rural junior secondary schools in the Qumbu Education District in the Eastern Cape, South Africa. This was done because in South Africa before the 1994 elections rural schools were not supported by the apartheid government. Rural areas were disadvantaged in education, in terms of finance. This resulted in poor quality of teaching and learning. Declining numbers of learners in rural schools was occurring in all rural schools. Staffs were alarmed by the declining enrolment of learners in their schools because their schools were affected. Teachers were redeployed to schools where there were sufficient learner numbers. Department of Education due to declining learner numbers in schools introduced rationalisation and re-alignment of schools, meaning closure of some schools with low learner numbers. This led to learners walking long distances to schools. This study was conducted in the Qumbu Education District. It focused on declining numbers of learner enrolment. The literature internationally focused on declining number in enrolment of learners. These learners were afraid of Physical Science (Chemistry side) as a subject. They had taken Chemistry as difficult because of the perceived link with Mathematics. Continentally the literature had alluded to teenage pregnancy, affected and infected learners with HIV/AIDS and human trafficking. In South Africa literature focused on the educational level of parents. Learners with educated parents leave rural schools to study in urban areas because of poor education which is provided in rural areas. Lack of resources in these schools could also be the cause of declining learner numbers in rural junior secondary schools. The study used a quantitative research design to elicit data from the respondents. The respondents in this study were 50 principals of the sampled rural junior secondary schools. Data was collected from 50 participants through the use of a questionnaire; 50 questionnaires were returned and the data which was finally processed was from these 50 questionnaires. The Statistical Package for Social Sciences (SPSS) was used for the analysis of the data. iii The findings of the study revealed that factors such as lack of parental involvement, socio-economic factors, HIV/AIDS - related issues, culture and gender - related issues, lack of resources, teacher and teaching - related issues and the education level of the parents were the contributing factors to the decline in enrolment of learners in rural junior secondary schools in the Qumbu Education District. In the light of the findings, the researcher recommends that more tuition time and the reduction of absenteeism by teachers can help reduce the decline of enrolment in rural junior schools in the Qumbu area. The Department must consider the number of learning areas and not teacher - pupil ratio. The Department should also introduce computer classes, woodwork, bricklaying and other practical skill subjects in these schools. Furthermore there must be resources such as laboratories, libraries and television. Some of the limitations encountered by the researcher during the study included the reluctance of the participants to take part in the research, the inaccessibility of schools in deep rural areas, the slow return rate of completed questionnaires and the obtaining of permission to undertake the study.

  • Description: Readmission of mental healthcare users is a global challenge and concern which is associated with high costs. Readmission has negative effects as it is believed to promote dependency, demoralize patients and cause workload for staff. Re-admissions also bring a burden to caregivers and affect the caregiver’s health. In the light of this background, the aim of the study was to explore and describe factors enhancing readmission of mental health care users (MHCUs) to a mental health unit in East London as described by their caregivers. The objectives of the study were to: explore factors enhancing readmission of mental health care users in a mental health unit in East London as described by their caregivers and to document recommendations elicited from the findings of the study. A qualitative approach was used to collect and analyze data. The study used a descriptive and explorative design. Sampling was done using the purposive non-probability method. Unstructured face- to- face interviews were conducted using an interview guide. Fifteen (15) caregivers of MHCUs who had been readmitted to a mental health unit in East London were interviewed .The interviews were recorded and transcribed verbatim. The findings of this study suggest that non adherence to treatment, refusing to take treatment, defaulting treatment, denial, indulging in substance abuse, stigma, effects of disease, violence and aggressive behavior are the factors enhancing readmission of MCHUs to a mental health unit in East London. A better understanding of readmission of MHCUs can lead to early intervention and early planning of care. It is envisaged that psycho education, home visits and collaboration of clinic staff with hospital staff may decrease readmission of mental health care users in this unit.

  • Description: Sustainable agriculture is explained by Reddy (1995: 22) as the ability for agricultural projects to produce crops and at the same time be able to maintain production without failing. With growing populations in urban areas, the importance of urban agriculture has become increasingly important. This research aims to study the factors that contribute to the success and failure of selected urban agricultural projects within the Nelson Mandela Bay by looking at how the community benefits from two selected community projects. It is however important to note that there are various factors contributing to the success and failure of any project. This research looks into the viability of the environment that the projects are in, the level of community membership, ownership structures, how messages are communicated between stakeholders, and the purpose of the project as well as the resources available to see the project through. Urban agriculture becomes a very important practice to the urban poor, as it subsidizes household income when the produce is sold and reduces expenditure when it is consumed (Kirkland, 2008: 23). Zooming into the Nelson Mandela Bay, it is evident that this practice is also beneficial for the communities in which the projects operate, however, challenges such as theft make such projects dependent on funders and donors.

  • Description: The development that has taken place in the health care sector includes all factors that have brought changes in the consumer decision-making process regarding the private health institutions. In Nigeria, the development is evident in the delivery of the health care services. This indicates that the private health institutions deliver quality health care service by using efficient and quality medical equipment. However, there is a growing awareness among clients to perform an extensive search before the purchase of health care service and the increased expectation from health care quality by clients and their family. The change in consumer behaviour has caused a shift in the consumer decision-making process due to the availability of several sources of information and various health institutions they can choose from. The purpose of this study is to investigate the factors that influence the consumer decision-making process that can enhance customer satisfaction and reduce cognitive dissonance. In this study the behaviour of consumers is related to how they make decisions along several stages before they make a purchase and in a health care setting the decision-making process refers to the process that clients pass through in making choices on alternative health institutions. The quantitative research method was adopted in this study in describing, analysing and interpreting data. A structured questionnaire was employed to collect primary data from 450 respondents in Lagos state, Nigeria. The primary data was statistically analysed using five stages, namely, exploratory factor analysis, Cronbach‟s alpha reliability testing, descriptive statistics, multiple regression analysis, and Pearson correlation analysis. The empirical results of this study indicates that service encounter experience, personal income and support sources are significantly related to the decision-making process. The decision-making process also has significant positive relationship with both customer satisfaction and cognitive dissonance. This indicates that influential factors that have been identified through the empirical results enlighten researchers and the private health institutions on issues that influence the clients‟ decisions to utilise private health institutions. The well-being and satisfaction of clients will be enhanced if the private health institutions can craft effective strategies that will enable clients to gain easy access and utilise health care services. This study emphasised that access to and utilisation of health care services in the private health institutions can be granted to clients through personal income and support sources from family members and private health institutions. Futhermore, health insurance coverage is an effective way that will help clients overcome the financial constraints and restricted access to and utilisation of private health institutions. The study further reveals that the well-being and satisfaction of clients will be enhanced if private health institutions improve access to quality health care. Failure to improve the overall quality and performances of the health care services in the private health institutions can lead to clients‟ cognitive dissonance. Both private and public health institutions should play a major role in providing the necessary facilities that can assist the clients in their decision-making process regarding their health care needs. This will enable the health care institutions‟ staff to understand what clients value and need and, therefore, how well to satisfy them and reduce cognitive dissonance. Easy access and utilisation of the private health institutions as well as satisfaction in quality health care delivery will create better health outcomes for the workforce and citizens of a country and this will improve economic development.

  • Description: A lot of attention over the years has been focused on understanding employees resistance to change. A few researchers have provided insights into the reasons why some employees remain positive and engaged during times of uncertainty and changes in the organosation. To help build this knowledge area the study was aimed to investigating the factors that drive employee engagement during change. One-hundred-and-twenty employees, across a cross-section of jobs at a specific bank in South Africa, were surveyed. The empirical results obtained from the survey showed that independent variables such as dialogue, organisational culture and a clear4 career plan were congruent with the expected results. In other words these vriables displayed a significant association with the de[endent variables (e.g. job involvement, organisational commitment and organisational citizenship behaviour.).

  • Description: Bull sharks (Carcharhinus leucas) are globally distributed top predators that play an important ecological role within coastal marine communities. However, little is known about how the spatial and temporal scales of their habitat use are associated with their ecological role. In this study, a population of sub-adult and adult bull sharks were investigated within a remote subtropical marine community in the southwest Indian Ocean off the coast of southern Mozambique. The main objectives of the study were to test a minimally invasive remote biopsy sampling method; to investigate the feeding ecology of bull sharks; and to investigate the temporal and spatial scales of bull shark residency patterns and migration dynamics. Biopsy tests on free-swimming bull sharks showed that the devised sampling technique provided a minimally invasive and consistent method (biopsy retention rate = 87%) to obtain muscle tissue samples sufficiently large enough (310±78mg, mean ± SD) for stable isotope analysis. Results from the stable isotope analysis showed that adult bull sharks appeared to exhibit a shift towards consistentlyhigher trophic level prey from an expanded foraging range compared to sub-adults, possibly due to increased mobility linked with size. Additionally, bull sharks had significantly broader niche widths compared to top predatory teleost assemblages with a wide and enriched range of δ13C values relative to the local marine community, suggesting that they forage over broad spatial scales along the east coast of southern Africa. Results from the passive acoustic telemetry investigation, conducted over a period between 10 and 22 months, supported these findings showing that the majority of tagged adult sharksexhibited temporally and spatially variable residency patterns interspersed with migration events. Ten individuals undertook coastal migrations that ranged between 433 and 709km (mean = 533km) with eight of these sharks returning to the study site. During migration, individuals exhibited rates of movement between 2 and 59km.d-1 (mean = 17.58km.d-1) and were recorded travelling annual distances of between 450 and 3760km (mean = 1163km). These findings suggest that adult bull sharks are not the sedentary species once thought to be but rather, consistently move over broad spatial scales on the east coast of southern Africa and play an important predatory role shaping and linking ecological processes within the southwest Indian Ocean.

  • Description: This thesis project examines the work of three female Nigerian authors: Chimamanda Ngozi Adichie, Sefi Atta and Chika Unigwe. They are part of a growing number of young African writers who are receiving international acclaim and challenging narratives that have long defined the continent in pejorative terms. They question what it means to be female and African in a transcultural, global world but counter discourses that are both restrictive and prescriptive. Their female characters are not imaged in binary terms as either victims or villains. For all three writers, the African story has to be told in its entirety incorporating what some may argue are negative stereotypes but doing so in a manner that examines and undermines those same stereotypes. For the purposes of the thesis, I focus on their first novels: Adichie’s Purple Hibiscus, Atta’s Everything Good Will Come and Unigwe’s On Black Sisters’ Street. Chapter One examines Purple Hibiscus and argues that the novel is much more than a coming of age story or, as some critics have posited, an allegory of the postcolonial state. Chapter Two highlights Atta’s use of fairly familiar feminist theories but grounds them in the lived realities of the African city. All three authors are concerned with issues of violence and death. Unigwe’s novel, which forms the focus of Chapter Three, offers a critical perspective on how both of those themes intersect with the increasing commercialisation of global culture. Her characters are female sex workers whose lives are irrevocably altered by the murder of one of their colleagues. I conclude by arguing that the three novels offer a nuanced if not necessarily new understanding of the various social, economic and political forces that continue to shape the lives of women on the continent.

  • Description: This thesis provides in-depth information on the high speed optical transport requirements for the Square Kilometre Array. The stringent data rates as well as timing and synchronization requirements are dealt with respect to the optical fibre technology. Regarding the data transport, we draw a clear comparison between a typical telecommunication access network and a telescope network. Invoking simulations and experiments on the field and laboratory test bed, we successfully implement a suitable telescope network using vertical cavity surface emitting laser (VCSEL) technology. Polarization effects on the KAT-7 telescope network, an operational prototype for the SKA is studied so as to estimate the expected effect in the MeerKAT telescope with transmission distances _ 12 km. The study further relates the obtained values to the expected impact on the distribution of the time and frequency reference in the MeerKAT array. Clock stability depends on the differential group delay (DGD) and polarization stability. On a 10:25 km link that includes the riser cable a DGD of 62:1 fs was attained. This corresponds to a polarization mode dispersion (PMD) coefficient of 19:4 fs=km1=2. This is a low PMD value considering telecommunication network. The PMD value is within the allowed budget in the telescope network. However, this may not be the case at longer baselines extending to over 1000 km as expected in SKA 2. The fibre's deployment contribution to the DGD is measured by comparing the deployed fibre to the undeployed of equal lengths. On the 10:25 km deployed single mode fibre, the maximum and mean DGDs measured were 217:7 fs and 84:8 fs respectively. The undeployed fibre of similar type and equal length, gave a maximum and minimum DGDs of 58:6 fs and 36:3 fs respectively. The deployment is seen to increase the maximum and minimum DGDs by factors of 3.7 and 2.3 respectively. This implies that fibre deployment is very critical in ensuring the birefringence is minimized. Polarization fluctuation recorded a maximum of 180o during the 15 hour real time astronomer use of the antenna. To ascertain the contribution of the riser cable, state of polarization (SOP) of the buried section of the single mode fibre in the link was established. A maximum SOP change of 14o over 15 hour monitoring was measured. From the stability realized on the buried section of the fibre, the change in polarization is contributed by the riser cable. The fluctuation in polarization can cause the phase of a clock signal to drift between the birefringent axes by an equal amount corresponding to DGD. We experimentally demonstrate how polarization stabilization can be attained using the polarization maintaining fibre. We also demonstrate the applicability of VCSEL technology in the SKA unidirectional data flow especially for shorter baselines < 100 km. The VCSEL is a low cost light source with attractive advantages such as low power consumption, high speed capabilities and wavelength tuneability. This work entails the use of traditional amplitude modulation commonly known as non-return-to-zero (NRZ) on-off keying (OOK) because of its simplicity and cost. For the MeerKAT typical distances, we show that even in a worst case scenario, the use of VCSEL on different fibres in MeerKAT distance is achievable. Using the impairment reduction approach, we successfully manage to achieve transmission distance beyond MeerKAT. Several in-line dispersion compensation mechanisms in telecommunication have been successfully employed. The work focused on the use of negative dispersion fibre to mitigate the chromatic dispersion effects in the optical fibre. The inverse dispersion fibre (IDF) is proposed for compensation in the conventional zero dispersion wavelength fibres, G.652 that are used at the third window. Similarly, the chromatic dispersion compensation of non-zero dispersion shifted fibre (NZDSF) is experimentally demonstrated using negative dispersion submarine reduced slope (SRS), G. 655 (-). With dispersion management, we demonstrate how transmissions beyond MeerKAT baselines can be achieved error free. A systematic investigation of the use of distributed Raman amplification to overcome the attenuation losses is provided. High on-off gains of up to 15 dB, 8 dB and 5 dB for bidirectional, forward and backward pumping respectively is achieved on a 25 km Raman optimized NZDSF-Reach fibre. Combined dispersion mitigation technique and low noise distributed Raman amplification, up to about 80 km transmission was achieved on a 4:25 Gbps modulated VCSEL using a single pump. Using bidirectional pumping, more than 100 km of transmission was achieved error free. The high gains enhance the VCSEL transmission distance. We further suggest a novel way of using the Raman pump to distribute the clock signal while amplifying the data signal streaming the astronomical data from the remote placed telescope receivers. In summary, the work presented in this thesis has demonstrated the potential use of VCSEL technology for data collection in the telescope array. We have studied the optical effects and mitigation so as to improve the clock and data transmission. This work is relevant and valuable in providing SKA with VCSELs, an option for extremely high network performance at reasonable costs.

  • Description: The popularity and viewership of Nollywood films have expanded across African countries as well as European and American cities especially those with considerable Diaspora population. This appears to underscore the assumption that Nollywood films not only project or transmit the embedded Nigerian cultural values to audience members but also actually make appreciable impression on those audience members. This study sought to ascertain the role of Nollywood film in the transference of Nigerian cultural heritage across other cultures using students at the University of Fort Hare as a case study. This study sought to determine if audience members learn, imbibe or manifest any behavioural tendencies that can be ascribed to the influence of watching Nollywood films. Specifically the study sought to establish the aspect of Nigerian culture that Nollywood films transmit to audience members. The survey research method was used while data was analysed using descriptive statistics. In all, 400 questionnaires were distributed while 370 were returned. Results show that students who were exposed to Nollywood film could mimic some common Nigerian expressions and exclamations. A small percentage of viewers could actually speak a smattering of some Nigerian language while a few have bought or made dresses in the pattern of what they saw in the films. It could be concluded that Nollywood films do exert significant influence on the viewers in the University of Fort Hare.

  • Description: Attaining high levels of economic growth and development has been one the goals of the Southern African Development Community (SADC). This paper investigates the relationship between financial liberalisation and economic growth in SADC countries. Annual data for the 15 SADC countries for the period 1985-2011 was used to develop a fixed effect model, generalised method of moments (GMM) as well as the fully-modified OLS (FMOLS) cointegration test. The results revealed that there is a positive relationship between financial liberalisation and economic growth in SADC but there is no long-run relationship between the two variables. It is recommended that the SADC adopt measures to increase the level of financial openness in the region in order to increase economic growth but this policy should be supplemented by other growth enhancing policies in order to increase economic growth over the long-term. However, prior to the increase in the level of financial openness, well-defined property rights and a sound regulatory framework should be in place to monitor the financial liberalisation process in order to avoid financial crises.

  • Description: The implementation of water policy and the integrated management of water face multiple challenges in South Africa (SA), despite the successes of post-apartheid government programmes in which some significant equity, sustainability and efficiency milestones have been met. This study uses a series of intervention processes into municipal water service delivery to explore the context, constraints, and real-world messiness in which local water authorities operate. The equitable provision of drinking water by local government and the collaborative management of untreated water by ‘water user associations’ are two sites of institutional conflict that have been subjected to broad ‘turnaround’ and ‘transformation’ attempts at the national level. This thesis seeks to explore and understand the use of transdisciplinary research in engaging local water authorities in a process of institutional change that increases the likelihood of equitable water supply in the Lower Sundays River Valley (LSRV). Fieldwork was conducted as part of a broader action research process involving the attempted ‘turnaround’ of the Sundays River Valley Municipality (SRVM) between 2011 and 2014. A multi-method research approach was employed, which drew on institutional, ethnographic, and systems analyses within an evolving, transdisciplinary methodology. In the single case study research design, qualitative and quantitative data were collected via participant observation, interviews and documentary sources. Analytical methods included system dynamics modelling and an adapted form of the ethnographic tool of ‘thick description’, which were linked in a governance analysis. Government interventions into the SRVM failed to take account of the systemic complexity of the municipal operating environment, the interactions of which are described in this study as the ‘modes of failure’ of local government. These modes included the perpetual ‘firefighting’ responses of municipal officials to crises, and the simultaneous underinvestment in, and over-extension of, water supply infrastructure, which is a rational approach to addressing current water shortages when funds are unavailable for maintenance, refurbishment, or the construction of new infrastructure. The over-burdening of municipalities with technocratic requirements, the presence of gaps in the institutional arrangements governing water supply in the LSRV, and the lack of coordination in government interventions are analysed in this study, with policy recommendations resulting. The primary contribution of this study is in providing a substantively-contextualised case study that illustrates the value of systemic, engaged, extended, and embedded transdisciplinary research.

  • Description: Exchange rates are one of the most essential determinants of a country's economic performance in terms of level of trade. Since the exchange rate is one of the best indicators of competitiveness, this study sought to examine the behaviour of the rand against other emerging countries in the South African exchange market. The study explored the trends and estimated the forecasting accuracy of six currency markets using ARCH-family and Random walk models over the period 1994 to 2013.The six currency markets examined were the Rand/Dollar, Rand/Pound, Rand/Euro, Rand/Yen and Rand/Pula. The Rand exchange rates did exhibit the characteristics of volatility clustering and asymmetric effects suggesting volatility of the Rand. Exchange rates tend to rise when there is more bad news in the financial market than good news and positive shocks imply a higher next period conditional variance than negative shocks of the same sign.

  • Description: Modern organisations make substantial investments in Information Technology (IT). Corporate governance practices can no longer ignore the importance of effectively governing IT. Consequently, the third King Report on Corporate Governance (King III) makes specific provision for IT governance, which is implemented through the establishment of an IT governance framework. The purpose of this research is to develop a generic IT governance framework, suitable to any large South African organisation in the public or private sector. The literature considered for this research confirmed the extent of standards and practices available in support of IT governance, together with the roles and structures required to implement them. These included well-known publications such as COBIT, Prince2, ITIL and ISO/IEC27000. Based on the literature review, a theoretical Processes, Enablers and Structures (PES) IT Governance Framework was formulated. The framework was further explored by means of a survey of and structured interview with ten Chief Information Officers (CIOs) of South African organisations with a turnover in excess of R1bn per annum. The final PES IT Governance Framework comprises three dimensions, each of which contains a set of constituent components: • Processes: Strategic Alignment, Value Delivery, Resource Management, Risk Management and Performance Measurement. • Enablers: IT Sub Processes, Supporting Documentation, IT Control Framework, Technology Architecture, Desirable Practice, IT Portfolio Management and Regulation. • Structures: The Board, Office of the CIO, IT Steering Committee, Technology Architecture Forum, IT Programme Management Office and Information Security Organisation. As the number of regulatory requirements and associated compliance pressures grow, the importance of an effective IT governance framework also becomes more prominent. The PES IT Governance Framework offers a uniquely practical approach to addressing IT governance principles that are often regarded as abstract. The final PES IT Governance Framework provides clear guidance on how organisations could implement an IT governance framework, which addresses the strategic alignment of IT to business, value delivery by IT investments, IT risk management, IT resource management and IT performance measurement.

  • Description: The traditional approach of Quality by Testing (QbT) limits the assurance of product quality to in-process and post-production testing. To overcome these limitations, a more proactive and systematic means to product development and optimisation is required. Quality by Design (QbD) is an example of such an approach which focuses on understanding the product and its manufacturing process and emphasises that quality should be built into the product and not merely tested. The study aims to optimise ethionamide tablets, an immediate release oral solid dosage form using QbD.

  • Description: Tenofovir disoproxil fumarate (TDF) is a novel nucleotide analog reverse transcriptase inhibitor that is recommended by the WHO for use in first line treatment of HIV infections. Due to the high dose of TDF for anti-retroviral treatment the formulation of a pellet dosage form may improve patient adherence by incorporation of a large dose in a relatively small dosage form. TDF is currently only available in tablet form. A simple, sensitive, selective, rapid, accurate, precise, stability indicating reversed-phase HPLC method was developed and validated in accordance with ICH guidelines and was successfully used for the analysis of TDF raw material and pharmaceutical dosage forms. Preformulation studies included an investigation of TDF-excipient and excipient-excipient interactions with all materials that could potentially be used to produce extruded and spheronized pellets. Nuclear Magnetic Resonance spectroscopy (NMR), Infrared Spectroscopy (IR), Differential Scanning Colorimetry (DSC) and Thermogravimetric analysis were used for identification and purity testing of TDF and all excipients. DSC data revealed that no potential interactions between TDF and the excipients occurred suggesting that incompatibility reactions were unlikely during manufacture and storage. These findings were confirmed by IR analysis that revealed that no physical interaction was likely between any of the excipients used and TDF. DSC data also reveal the existence of the α and β-polymorphs of TDF as evidenced by two enthalpy changes observed on the resultant thermograms. The existence of two polymorphs is unlikely to result in incompatibility and was confirmed by IR analysis. The IR spectra reveal that all characteristic peaks for TDF were present in 1:1 binary mixtures. Therefore TDF is compatible with all excipients tested and thermal analysis confirmed the stability of TDF under manufacturing conditions. The temperature of degradation temperature established through DSC analysis confirmed that degradation during manufacture is unlikely as the temperature of manufacture is lower than that at which degradation occurs. Extrusion and spheronization were the processes used to manufacture TDF pellets as it is a simple and economic approach for production. The effects of extruder and spheronizer speed, amount of spheronization aid and diluents on the pellet size, shape, flow properties and TDF release characteristics were examined. In order to decrease the complexity of analysis and reduce the cost of development a Taguchi orthogonal array design of experiments was successfully applied to evaluate the impact of formulation variables on product characteristics and predict an optimized formulation with a minimum number of experiments. The use of Response Surface Methodology for the development and optimization of pharmaceutical systems, including the optimization of formulation composition, manufacturing processes and/or analytical methods is well established. However the application of RSM requires that accurate, precise and reproducible experimental conditions are used for the generation of reliable data and RSM use is limited due to sensitivity to experimental variability. The benefits of using RSM for formulation optimization include the fact that more than one variable can be investigated at a time and large amounts of information can be generated at the same time ensuring a more efficient process with respect to time and cost. An added advantage of this approach is that mathematical relationships can be generated for the models that are produced and provide formulation scientists with an indication of whether the effect(s) between factors are synergistic or antagonistic. There are several statistical design approaches that use RSM and a Taguchi orthogonal array design was selected for use in this optimization process as fewer experiments are required to generate data for the same number of factors to be investigated when compared to other statistical designs such as Central Composite (CCD) and Box-Behnken designs. The use of RSM clearly demonstrates the impact of different input variables on the % TDF released at 45 min and % TDF loaded into the particles. The amount of sorbitol and Kollidon® CL-M were the only significant variables that affected the % TDF released at 45 min and both excipients had an overall synergistic effect on the in vitro release of TDF. The prediction and manufacture of an optimized formulation led to the production of pellets that met predetermined specifications which was successfully achieved using RSM. The development of a TDF containing pellet dosage form has been achieved and the formulation, manufacture and characterization of the dosage form reveal that the product has the potential to be further developed.

  • Description: The purpose of this study was to investigate and foster corporate citizenship (CC) in the SA taxi industry. The primary objective of this study was to foster corporate citizenship in the South African taxi industry by investigating the determinants that would increase CC in the SA taxi industry. The study gathered quantitative information about CC, identified which factors influence CC in the taxi industry and investigated which of these factors are the most important determinants that would increase the CC in the industry in South Africa. This study was intended to contribute to building the body of knowledge for the implementation and fostering of corporate citizenship programs. In particular, the researcher hoped that the framework provided in this study would outline the practical strategies that the taxi organisations should take in developing targeted, long-term partnerships with the communities in which they operate. Convenience sampling was used to select one hundred (100) participants. The response rate was ninety-six percent (96%). The sample was structured to include the directors, deputy directors, senior managers, managers and the drivers of the taxi organisations in twenty-three districts in the Eastern Cape. These participants were taken from the body that incorporates all the taxi associations in Eastern Cape called the Eastern Cape Bus and Business Chamber (ECBTBC). The empirical results revealed that in order to increase corporate citizenship within the SA taxi industry there should be an increase in its human resource management, operations management and the dynamic externalism of its members. The findings also revealed that the social cynicism should be decreased within this industry.

  • Description: Mechanical fasteners are used extensively in the joining of two or more metal plates or sheets. Riveted joints have been the joints of choice mainly for the Aerospace Industry. However for this research, Friction Hydro Pillar Processing has been used to develop and characterise a new riveting technique termed Friction Hydro Pillar Riveting (FHPR). Two overlapping 3.17 mm Ti-6Al-4V sheets were joined together using Ø6 mm rivet which was friction processed. This research has focussed on the initial development of Friction Hydro Pillar Riveting thereby establishing a basic understanding of the influences of main process parameters, rotational speed and axial force - and also joint configurations. The results showed that with a decrease in the bottom hole chamfer angle, there was resulting overall increase in the rivet joint pull off strength. From the best performing joint configuration in pull off tests, shear tests were conducted whilst a blind hole FHPR joint was also done and tested in pull off and shear strength. The shear test fracture surfaces exhibited ductile failure. The microstructure of the joints was thus evaluated. From parent material, heat affected zone and to weld zone there was a variation in the microstructure analysed. The hardness profiles showed increased hardness in the weld zone which partly explained the shear results. The hardness increase was mainly due to grain refinement in the weld zone by the Friction Hydro Pillar Riveting process.

Friend or foe? : Resolving the status of the submerged macrophyte Myriophyllum spicatum L. (Haloragaceae) in southern Africa

  • Description: Myriophyllum spicatum L. (Haloragaceae), a submerged macrophyte, has been recorded in southern Africa since 1829, but only considered problematic as recently as 2005. In light of this, water resource managers are looking to control M. spicatum in southern African water bodies where it is problematic. Amongst control options available in South Africa, biological control is potentially the most cost effective and sustainable option for M. spicatum. However, there is a debate over the status of this plant in southern Africa with several authors reporting it as a native component of the aquatic ecosystem, while others argue that it has been introduced from Europe or Asia. The aim of this thesis is to use a multifaceted approach to resolve the status of M. spicatum, by studying aspects of its history, distribution, mechanisms of its adaptations, biotic interactions and genetic relationships in southern Africa. By resolving the status of this plant as either native or exotic, appropriate management strategies can be initiated for its control in situations where it is considered a problem.A review of the evidence collected from this thesis does not provide convincing evidence for the anthropogenic introduction of M. spicatum into southern Africa, and it is probably native to the region. The disjunct distribution as well as regular local extinctions of populations is relatively common for species that are at the edge of their range. The populations in southern Africa could thus be relics from a much wider distribution in the past. The development of local adaptations in southern Africa provides evidence for this and suggests that the populations have been isolated for a substantial period of time and have had a long evolutionary history in the region. The lack of specialist herbivores should suggest that M. spicatum has been introduced, but the complete lack of herbivores, including generalists, may weaken that argument. The lack of herbivores could be a result of something inherent in the plant, irrespective of a lack of evolutionary history in the region. The genetic evidence suggests a European origin, but is characteristic of a population (southern Africa as a whole) that has been isolated for a considerable time. Despite the findings of this research, M. spicatum is considered problematic in southern Africa and warrants control in certain systems. Whether or not biological control should be a component of the management strategy is open to further debate. The benefits in a southern African context may outweigh the risks, based on the specificity of the biological control agent proposed. However, the perceived negative impacts of M. spicatum are likely to be a symptom of a more serious underlying cause, such as nutrient loading and changes in land use patterns. Therefore the control of this native species is a water resource management issue and not a biological control issue.

  • Description: The fact that pilots are not physically situated in the aircraft for UAS operations makes the current standards applicable to manned aircraft not suitable for UAS operations (FAA, 2013). FAA (2013:18) states that ―removing the pilot from the aircraft creates a series of performance considerations between manned and unmanned aircraft that need to be fully researched and understood to determine acceptability and potential impact on safe operations in the NAS. According to ERSG (2013), not all technologies necessary to ensure the safe integration of civil UASs into civilian airspace are available today. The extrapolation that can be made based on the above arguments is that advancement of UAS technologies will more likely have a significant bearing on the safe integration of UASs into civilian airspace. Therefore, as an identified research gap, the research/main objective of this research is to identify future technological factors affecting Unmanned Aircraft Systems in the Republic of South Africa leading towards the year 2025.
