- Description: The term "road infrastructure" refers to the roads and structures that are used to convey commuters and goods. In the numerous road facilities, structures, road classifications, electronic traffic systems, signage, and markings, the mission of road infrastructure is to assist efficiency by providing safety and trouble-free transportation. There are fundamental elements that determine the availability of resources required in society and the efficiency with which they are used to accomplish economic growth. Investment in public capital, such as road infrastructure, which is a major economic engine, is critical because infrastructure helps an economy thrive. The importance of road infrastructure and the major role it plays in economic growth can be seen in studies in developed European nations, New Zealand and the Slovak Republic, where road infrastructure is regarded as a catalyst for economic progress. Investment in public capital, such as road infrastructure, has economic benefits since it acts as the economy's backbone. The Eastern Cape's growth has been acknowledged and included in South Africa's national development strategies and efforts; nonetheless, based on deliverables and results, the province ranks among South Africa's least developed provinces. The Eastern Cape has long been designated by development programmes such as the Spatial Development Initiative (SDI) as an area that will not only generate development and progress for the province, but also for South Africa as a whole. This is sought to be achieved by the Spatial Development Initiative for the Wild-Coast in OR Tambo District Municipality, which states that "integrated sustainable rural development in the context of community, public, and private partnership initiatives.”, p. 2) This research contributes to the goal of research, which includes testing, the identification of causes and consequences, the building of a foundation for future research, and the growth of knowledge (Apuke, 2017, p. 40). The study follows a quantitative research approach and uses two main methodological procedures in order to complete this study; namely a literature review and questionnaire survey. Employees of the South African Department of Transport's National Road Infrastructure implementing agent SANRAL make up the research population in this study. The study concludes that the delivery of an effective road network in the OR v Tambo Region can serve as the base for the establishment of innovative PPP policies, the pillar of socio-economic development and transformation. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: Lignocellulosic biomass is the most abundant source of renewable biomass on earth. Lignocellulosic biomass consists of cellulose, hemicelluloses and lignin. These can be used as a source of renewable fuel as well as other value-added products . Mannans are part of the hemicellulose fraction of lignocellulosic biomass and are the major hemicellulosic polysaccharide fraction in softwoods, where they are found as galactoglucomannans and as glucomannans. Mannans are also found in hardwoods in the form of glucomannans. Mannans can be enzymatically hydrolysed using endo-mannanases to produce of short chain mannooligosaccharides (MOS). MOS have received significant attention for their prebiotic properties, as they promote the growth of probiotic bacteria, which have positively affects on gut health. This study focused on the production of prebiotic MOS from lignocellulosic biomass waste (LBW) and an evaluation of the prebiotic potential of the produced MOS. An Aspergillus niger derived endo-mannanase, Man26A, was fractionated and biochemically analysed. Purified Man26A had a fold purification of 1.25 and a yield of 41.1%. SDS-PAGE analysis of the enzyme revealed that it had a molecular weight of 46 kDa. The pH and temperature optima of Man26A were determined and the pH optimum was found to be pH 4.0 (but the enzyme displayed high activity over a broad acidic pH range, with up to 90% of the activity retained between pH 3.0 and 7.0). The temperature optimum was 50℃. The enzyme was shown to have the highest specific activity on locust bean gum (52.27 U/mg) and ivory nut mannan (57.25 U/mg), compared to guar gum (29.07 U/mg), which indicated that it was affected by the substitution pattern of the mannans. Man26A produced MOS of different diversity on model mannan substrates, where the MOS produced were mannobiose, mannotriose, and mannotetraose for ivory nut mannan, mannobiose, mannotriose, mannotetraose, and mannopentaose and MOS with a higher degree of polymerisation for locust bean gum, and mannobiose, mannotriose, mannotetraose, mannopentaose, and mannohexose and MOS with a higher degree of polymerisation for guar gum, as determined by thin layer chromatography (TLC) and high-performance liquid chromatography (HPLC). Pretreatment and characterisation of pineapple pulp (PP) and pine sawdust (PSD) was conducted, and the impact of the pretreatment procedures was analysed using Megazyme sugar kits, thermogravimetric analysis (TGA), Fourier-transform infrared spectroscopy (FTIR), and microscopic analysis using scanning electron microscopy (SEM) and light microscopy. Compositional analysis of the carbohydrates present in both substrates revealed that they had a glucan content of 36.41 and 50.47% for untreated PP and PSD, respectively. Their respective mannan content was 6.74 and 11.59% and was deemed sufficient for the production of MOS via enzymatic hydrolysis. TGA analysis revealed that untreated and sodium chlorite-acetic acid delignified samples decomposed at approximately the same time, and had a negligible ash content at 600℃, while delignified plus phosphoric acid swollen substrates decomposed at a faster rate, but had a residual ash content at 600℃. FTIR analysis of the substrates revealed slight changes in the structures of untreated and pretreated samples. SEM analysis of PP and PSD showed a change in the morphology of the substrates with subsequent pretreatment steps. Histochemical analysis for lignin for PP and PSD showed successful delignification upon pretreatment. Untreated and sodium chlorite delignified PP and PSD released low amounts of reducing sugars compared to delignified + phosphoric acid swollen substrates. The delignified + phosphoric acid swollen substrates were used for further experiments. MOS produced from delignified and phosphoric acid swollen (Del + PAS) PP and PSD at 0.1 mg/ml enzyme loading and 80 mg/ml (8% (w/v)) substrate concentration, ran between mannose and mannobiose and between mannobiose and manotriose on TLC, with low concentrations of MOS running between mannotetraose and mannopentaose. HPLC analysis of the MOS revealed that Del + PAS PP produced mannose to mannohexose, while Del + PAS PSD produced mannose, mannobiose, and mannotetraose. The MOS were analysed using FTIR, to determine whether the MOS produced contained any acetyl groups, which were present for Del + PAS PSD at 1706 cm-1. The MOS were stable at different pHs, and at temperatures below 200℃. The MOS were also found to be stable in a simulated gastrointestinal environment, in the presence of bile salts and digestive enzymes. The prebiotic effect of the MOS derived from Del + PAS PP and PSD was evaluated. MOS had a proliferative effect on probiotic bacteria (Lactobacillus bulgaricus, Bacillus subtilis and Streptococcus thermophilus). The production of short chain fatty acids (SCFAs) was evaluated on TLC, where no SCFAs were observed on the plate. The effect of MOS on the adhesion ability of bacteria revealed that they do not positively influence the adhesion of probiotic bacteria. The antioxidant activities of 1 mg/ml MOS produced from both substrates were determined to be approximately 15% using the ABTS radical scavenging assay, compared to a radical scavenging activity of 45% for the 0.02 mg/ml gallic acid standard. This study demonstrated that biomass waste could be used to produce prebiotic MOS, which play a positive role in gut ecology and provide health benefits. , Thesis (MSc) -- Faculty of Science, Biochemistry and Microbiology, 2022

- Description: Whitacre's music is primarily diatonic with subtle modulations, where the new key is always preserved diatonicaliy as well. I refer to this style as expanded diatonicism. Examples in my work of expanded diatonicism within this portfolio are to be found in navem ad somnium, Wynken, Blynken and Nod, as well as Hymn for Brass. My applications of expanded diatonic practices within each of these works are discussed in a separate appendix within the body of this portfolio. That these works are vocal or have a vocal inspiration (Hymn for Brass) reveals the extent of my initial reaction to Whitacre's music during a choral rehearsal. Furthermore, in my vocal compositions especially I chose texts which frequently gravitate towards ideas related to water, the ocean and ships. Whilst water has a soothing and inspiring influence upon me, presumably evidenced in my expanded diatonicism, it also represents my journey and investigation into the sound work of Whitacre in particular. It may be noticed that many of my works in this portfolio have religious orientated themes. I am a Christian, and belong to a Berean 2 Congregational Church. Whilst I am not Catholic or Anglican, I nonetheless have made use of texts from the liturgy of these denominations, as they emphasise the basis of my Christian faith. Why I chose Hymn for Brass as a title could possibly be construed as a religious reference, however it was named after the piece was written, and had no theological connotations in its inception save for the hymnody style of the orchestration. Providence and The Eventide both have a Christian philosophical foundation which is explored in depth in the accompanying appendix. The latter work explores an extension of my expanded diatonic style through incorporating aspects of chromaticism. The rationale for this is dealt with in my discussion of this work. This portfolio represents an overview of my compositional activities to date and displays my growing confidence with the technical aspects of composition as well as my yearning for experimentation with new ideas and manners of expression. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2007

- Description: The current study was conducted to determine the effect of feeding different inclusion levels of processed Mucuna pruriens on fatty acid composition and sensory attributes of broiler chickens. 120 Cob500 broilers were used in the experiment. The experiment was divided into 4 treatment (0, 10, 15 and 20 percent of Mucuna pruriens) groups, each treatment with 6 replicates (5 birds per replicate) in a completely randomized design. The first treatment (0 percent) was used as control against the three different levels of Mucuna pruriens. The birds were reared in a deep litter system until they reached slaughter weight of 2kg. At day 42 a total of 80 birds were slaughtered and breast muscles were sampled for the evaluation of sensory attributes and fatty acid composition. For sensory evaluation meat samples were prepared and boiled at 80°C until the internal temperature reached 82°C, 40 consumers were used to assess the meat samples and give scores according to 9-point hedonic scale. The fatty acid content was determined and recorded using the gas chromatography. Total saturated fatty acid (SFA), total monounsaturated fatty acid (MUFA), and total polyunsaturated fatty acid (PUFA) of the breast meat were not affected by diets. Omega-6 and omega-3 fatty acid were also not influenced by treatment diets. However, breast muscle from broilers fed 20 percent Mucuna pruriens seed meal inclusion had lower Myristic acid. The sensory attributes; aroma, colour, flavour, juiciness, tenderness and acceptability were assessed, dietary treatments affected the juiciness, tenderness and acceptability of meat, the treatments showed no significant difference on colour, aroma and flavour. Different age groups accepted the meat differently, the respondents that were between 18 and 22 years old gave the highest scores to the acceptability of meat than the other age groups, and different age groups also gave different scores in the aroma of meat. Females and males accepted the meat differently, the female respondents gave higher scores on the flavour of meat than males. Different inclusion levels of Mucuna pruriens positively affected fatty acid composition and sensory attributes of broiler chickens without causing any detrimental effects. , Thesis (MSc) (Animal Science) -- University of Fort Hare, 2021

- Description: Throughout history, animals have been domesticated and held captive in the interests of man. Animal captivity dates back to Ancient Egypt, however, as humanity has developed and further understood animals, their nature, importance and habitational needs, we have been able to appreciate and respect the value of each living thing that shares our planet alongside us. Humanity has progressed in its realisation that, our own species, is not so much superior to all living things, as it is one small, but very dominant part, of a larger system. This furthered understanding has altered the nature of animal captivity, no longer serving only the purposes of entertainment and observation, but also the interests of safeguarding and protecting our natural environment and all those that reside within it. The emergence of new technologies has advanced man’s ability to study and observe animals within their natural habitat, allowing study of the animals free of the limitations and impact of captivity on their psychological state. Harmful cultural beliefs and black market trade, have depleted the planet’s animal populations at an alarming rate, to the point that we can no longer sit idle while our rich natural resources and ecosystems are being devastated solely for economic gain. The efforts, interventions and support offered by African governments have fallen short in terms of the protection and rehabilitation of one of our continent’s most iconic large fauna, the rhinoceros. The war against illegal poaching has been taken up by private individuals. The cost of such efforts, however, weighs heavily on those who attempt to tackle the situation. To address these challenges, wildlife sanctuaries have developed safe havens for animals that have fallen victim to the illegal black-market trade. The design, construction and establishment of rhino sanctuaries is subject to specific legislation and prescribed regulations and standards for meeting the habitational requirements of the various sub-species of rhino. From an architectural standpoint, the narrative of an archi-type for ‘sanctuary’ has not yet been fully developed, as the high costs to private owners of game farms keeping rhinos - for those who have taken it upon themselves to provide for their shelter and enclosure - necessitate that such be undertaken using the most cost-effective means and approach through which to attain regulatory compliance. This treatise explores the narratives of the idealistic architectural approach to designing enclosures for the safeguard of wildlife species. Sanctuaries are designed to accommodate species-specific needs. The species of focus is the African black rhinoceros, the numbers of which, alongside its family of other sub-species, have been devastated by poachers and the black market trade to point of near extinction. The treatise explores the narratives of the ‘restrictive’ and ‘non-restrictive’ senses of animals in captivity through the programme of a sanctuary for black rhino. The aim of the treatise is to understand the specific requirements relating to a species’ natural habitat, and to adopt these principles in the design of an enclosure type that provides security and rehabilitation facilities within a non-stressful and safe environment through architectural intervention. The approach finds anchor in the narrative concerned with those conditions idealistic for a ‘cultural environment’ in which man and animal may dwell together in mutual harmony. This narrative focuses on the phenomenon of the natural versus the man-made, in order to understand meaning, identity and place within the programme of architectural design for wildlife. The Kruger National park exists as the largest natural reserve on the African continent and is situated at the frontlines of the illegal black market trade of rhino horn. This provides an ideal context within which the treatise explores the animal enclosure conceptually and towards serving the needs and requirements for the re-release of a rhino back into its natural habitat post-injury. The architectural intervention is to understand place, meaning and identity through the spatial implications of indigenous Sotho patterns and principles – those of a people whose understanding of context and culture have shaped the orientation of traditional settlements within a natural landscape. The physical form of the architectural intervention is derived from the existing natural materials found within the context of the treatise study, and from making use of affordable, eco-friendly methods and modes of construction. The treatise aspires to identify a new strategy and architectural type for the design of a wildlife sanctuary for poached and orphaned black rhino within an African context.

- Description: Throughout history, animals have been domesticated and held captive in the interests of man. Animal captivity dates back to Ancient Egypt, however, as humanity has developed and further understood animals, their nature, importance and habitational needs, we have been able to appreciate and respect the value of each living thing that shares our planet alongside us. Humanity has progressed in its realisation that, our own species, is not so much superior to all living things, as it is one small, but very dominant part, of a larger system. This furthered understanding has altered the nature of animal captivity, no longer serving only the purposes of entertainment and observation, but also the interests of safeguarding and protecting our natural environment and all those that reside within it. The emergence of new technologies has advanced man’s ability to study and observe animals within their natural habitat, allowing study of the animals free of the limitations and impact of captivity on their psychological state. Harmful cultural beliefs and black market trade, have depleted the planet’s animal populations at an alarming rate, to the point that we can no longer sit idle while our rich natural resources and ecosystems are being devastated solely for economic gain. The efforts, interventions and support offered by African governments have fallen short in terms of the protection and rehabilitation of one of our continent’s most iconic large fauna, the rhinoceros. The war against illegal poaching has been taken up by private individuals. The cost of such efforts, however, weighs heavily on those who attempt to tackle the situation. To address these challenges, wildlife sanctuaries have developed safe havens for animals that have fallen victim to the illegal black-market trade. The design, construction and establishment of rhino sanctuaries is subject to specific legislation and prescribed regulations and standards for meeting the habitational requirements of the various sub-species of rhino. From an architectural standpoint, the narrative of an archi-type for ‘sanctuary’ has not yet been fully developed, as the high costs to private owners of game farms keeping rhinos - for those who have taken it upon themselves to provide for their shelter and enclosure - necessitate that such be undertaken using the most cost-effective means and approach through which to attain regulatory compliance.

- Description: It is usually understood that the development of technological marketing capabilities by firms provides them with immense opportunities to transform their business practices and strategies, to strategically position themselves in the market and enhance firm performance. The main objective of this study was to determine the effect of marketing capabilities (Intellectual capital, marketing strategy and market orientation) on the competitive advantage of SMMEs. Prior research has that early development of marketing capabilities enables firms to achieve competitive advantage. The issue to be attended to will be to identify the connection between the incorrect marketing capabilities and failure of SMMEs, if there is any. Furthermore, a thorough investigation looking at how the reduction of failure of SMMEs can be realised by investigating the marketing capabilities of SMMEs. Quantitative research approach was used in the study, with a population of 200 SMMEs, the Raosoft calculator is also used to calculate the sample size of 100 SMMEs which were used to collect the primary data of the study. Convenience sampling method was used by the researcher. The findings also revealed that SMMEs adopt new and advanced technologies when marketing their products and services. The study recommends that SMME Owners/ Managers should consider spending a higher proportion of their time and money engaging in activities related to marketing throughout the life of their business. Therefore, it has concluded that effective deployment of marketing capabilities can lead to competitive advantage and greater performance. , Thesis (MCom) -- Faculty of Management and Commerce, 2020

- Description: The study sought to examine the extent to which the financing options chosen by entrepreneurs will have an impact on business success. The investigator adopted the progression of the ventures along the business life cycle stages as a benchmark for assessing success. The study focused primarily on small, medium and micro enterprises (SMMEs) in the Eastern Cape Information Communication Technologies (ICT) sector. An empirical study, using an online survey was conducted amongst 50 small business owners/ business representative within the ICT sector in the Eastern Cape Province. Key results revealed that the financial support of Broad-Based Black Economic Empowerment (BBBEE) and personal savings have played a key role in the success of ICT SMMEs throughout the business life cycle phases. This occurs after an ICT SMME has advanced successfully over the startup stage and aims for success in the development phase. The empirical finding revealed that for these SMMEs to attain success at this stage, they should finance their business investment projects utilising financing and credit trade in the form of bank loans, families, relatives and friends. According to the empirical finding in chapter five, the abovementioned financing options are only substantially linked to good advancement from the development phase onto the expansion phase. In addition, suggestions have been made to the ICT SMME management to include BBBEE finance, personal savings, bank loans, families, relatives and friends and trade credit as suitable funding choices for the ICT SMME's life cycle. The recommendations made included that proponents of the BBBEE legislation underpinning the enterprise development and supplier development, should intentionally pressure the private sector to comply with this legislation, as compliance will increase the pool of capital available to SMMEs.The chances of receiving these forms of support would therefore improve the probabilites of sucess for ICT SMMEs. Moreover, personal financing is crucial to successful progress for ICT SMMEs along the business life cycle. It is recommended that startup owners should always exercise iv saving in their personal capacity. In the early stages, the owner's capital will still be valuable as "seed financing" for start-up businesses., when all the other options of external funding are not available. Moreover, SMMEs should continuously explore the other financing options, such as bank loans, families, relatives and friends and trade credit only when their business goals are achieving success at the development stage. The study calls upon academia to consider performing descriptive studies to look at these findings. Through setting a concise financing approach for SMMEs in the ICT sector, SMMEs may help to close the distance between themselves and access to various financing options and supportive organisations. , Thesis (MA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: The Post-Provisioning Model (PPM) is a Resource Allocation Model (RAM) used by the Department of Education to optimize the distribution of available educator resources to public schools. The Department of Education adopted the PPM to distribute the total available posts to all public schools in an “equitable, transparent and resource-efficient manner. The PPM is a formula-driven model that primarily allocates educators, as human capital, to public schools based on learner enrolment numbers. In addition to allocating teaching staff, the PPM allocates the School Management Team (SMT) to each school. The outcome of the PPM formula is called the Post-Provisioning Norm (PPN). The implementation of the PPM has presented various challenges in the management of public schools. The primary aims of this study were to investigate any possible weaknesses of the PPM and to critically evaluate and explore school managers’ views of the PPM in the management of public schools. For the purposes of this study a probability sampling procedure was used. The participants were chosen from the principals within the Department of Education in Amathole East District. The literature review undertaken and the field research findings in the fourth chapter revealed that there is a gap between the ideals of the PPM and its implementation. It was found that there was a poor understanding of the technical aspects of the PPM formula among senior managers of public schools. There is evidence of equitable quantitative distribution of posts through the PPM. However, it was discovered that the PPM does not take into account the distribution of qualified educators. Hence, some of the allocated posts in public schools were often filled by under-qualified or non-qualified staff. The appointment of qualified educators was skewed. Further findings of this study revealed, amongst others, the inability of the PPM to provide for and promote the needs of a diverse curriculum in rural areas, and the inability to factor in and balance the variable that some public schools raise more money in school fees, which enables the advantaged schools to employ additional educators. The primary recommendations of this study are that principals be trained, on an annual basis, on the workings of the PPM and that the South African Schools Act No.84 of 1996 should be amended to grant authority to the Head of Department of the province to appoint and deploy qualified educators to public schools. , Thesis (MPA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: Sexual Reproductive Health (SRH) is a significant aspect of adolescent’s growth. Adolescents particularly girls face the risk of exposure to Human Immunodeficiency Virus (HIV), Sexually Transmitted Diseases (STDs), child marriages, high rates of unwanted pregnancy and the risk of those pregnancies can lead to unsafe abortion. In South Africa, considerable progress has been made in achieving improved access to Sexual Reproductive Health and Rights (SRHR) among the general population, however, some factors influencing SRHR of adolescents and young people have been slow to achieve. The study aims to investigate factors influencing Sexual Reproductive Health and Rights of adolescents in Alice, which is located in the Eastern Cape Province of South Africa. The Social-Ecological Model was considered appropriate for this study as it provides a comprehensive understanding of the multiple and interacting determinants of Sexual Reproductive Health and Rights. A qualitative methodology was adopted, involving focus groups with high school learners, in-depth interviews with institutional actors (Department of Health, Basic Education and Social Development), and participant observations. The study reveals that adolescents’ have access to Sexual Reproductive Health services from healthcare centres but only a few utilize or access them due to barriers such as the geographical location, denial and judgement about young people's sexuality limits their access to comprehensive knowledge to protect and promote their Sexual and Reproductive Health. The findings show that the adolescents who were most affected by Sexual Reproductive Health and Rights challenges were those from deep rural areas. They had minimal information/education compared to those residing in areas close to the town of Alice and major roads. Multi-sectoral interventions empowering adolescents and young people to exercise their rights to optimize SRHR service yield better results. , Thesis (MSc) -- Faculty of Science & Agriculture, 2021

Although these are several potential benefits of a healthy SMEs sector, stimulating economic growth through job creation, increased market competition and innovation are among the more the commonly reported benefits. Despite this, SMEs owner-managers, particularly those operating in the South African Market, are faced with several obstacles that impede their success, thus contributing to the high and persistent failure rates among SMEs. When considering that SMEs are often comprised of the owner-manager as the principal decisionmaker, their ability to make decisions are crucial to the sustainability and long term success of their businesses. Against this background, the primary objective of this study is to determine the influence of the owner-managers on the financial performance of SMEs operating in the Nelson Mandela Bay. The failure of SMEs are often attributed to the prevalence of financial literacy among owner-managers.

- Description: Unlike electromagnetic waves, gravitational waves self interact. This interaction is non-linear and can have very interesting properties which effect the curvature of space-time. A gravitational plane wave collider, implemented in the Python package COFFEE [20] that been developed in recent years by the Otago relativity group and implements the method of lines, can be reliably used to study this self-interaction. This was shown to work well numerically as profounded by Frauendiener, Stevens and Whale in 2014 [24]. For this reason, COFFEE will be used to study these gravitational wave propagations and subsequently collisions. The Einstein field equations are formulated as a well-posed initial boundary value problem (IBVP) in the Friedrich-Nagy gauge [26] and due to the large class of boundary conditions admitted by this framework, a variety of investigations into the propagation of plane gravitational waves could be carried out. This study focuses on the propagation of plane gravitational waves in the de Sitter (dS) space-time, which is the maximally symmetric solution of the Einstein’s vacuum field equations with a positive cosmological constant λ. There is substantial cosmological evidence that our universe is asymptotically de Sitter, yet no work, analytical nor numerical, has been done on gravitational plane waves propagating on such a space-time, mainly due to the increased complexity from the non-vanishing λ. Firstly, it is found analytically that with an arbitrary cosmological constant λ and a non-vanishing energy momentum tensor, the constraints will propagate. This means that we still have a wellposed IBVP, which is nontrivial since the Friedrich-Nagy gauge has only been shown to lead to a wellposed IBVP without matter [26]. Using this system, we consider one ingoing wave propagating on said space-time in vacuum. The area of the ingoing wave profile is varied and inferences are made about the different phenomena that arise in the curvature of space-time during the evolution. It is found that there exists a critical value of the wave’s area, ac, whereby taking the area below this value the system asymptotes to its initial state, and above the system diverges, indicating the presence of a singularity. Furthermore, we define an expansion parameter H to measure how the gravitational waves influence the accelerated expansion, generalising (numerically) results of Tsamis and Woodard. , Thesis (MSc) -- Faculty of Science, Mathematics, 2021

It is found that there exists a critical value of the wave’s area, ac, whereby taking the area below this value the system asymptotes to its initial state, and above the system diverges, indicating the presence of a singularity. Furthermore, we define an expansion parameter H to measure how the gravitational waves influence the accelerated expansion, generalising (numerically) results of Tsamis and Woodard. , Thesis (MSc) -- Faculty of Science, Mathematics, 2021

- Description: This study investigated the level of self-esteem of black and white high-school students using the Rosenberg self-esteem scale. One hundred and eighty six subjects were used, 63 of them being white while 118 were black. A validation of the Rosenberg scale for the black sample was attempted using a correlation between the scale score and a rating of the subjects by teachers. The results of the study showed no significant difference between the self-esteem levels, while the validation study failed to confirm the validity of the test for black subjects in South Africa. However, the validation study v/as rejected as inconclusive and the results of the comparison accepted as confirmatory of previous research. An incidental positive finding revealed that white males have higher self-esteem than white females,. The theory and past research of self-esteem comparisons between racial groups is reviewed. The conclusion is reached in this study that the concept of self-esteem has outlasted its usefulness in the field of comparisons between racial groups and research of a qualitative nature .can provide further data for the understanding of differences between racial groups. , Thesis (MA) -- Faculty of Humanities, Psychology, 1988

- Description: In this work, the selectivity behaviour of two host compounds, namely N,N’-bis(5-phenyl-5- ibenzo[a,d]cycloheptenyl)ethylenediamine (H1) and N,N’-bis(5-phenyl-10,11-dihydro-5- ibenzo[a,d]cycloheptenyl)ethylenediamine (H2), was assessed in mixtures of difficult-toseparate compounds, including the xylenes and ethylbenzene, pyridine and methylpyridines, and anisole and methylanisoles. These host compounds were synthesized using Grignard addition reactions with phenylmagnesium bromide on dibenzo[a,d]cyclohepten-5-one and 10,11- dihydrodibenzo[a,d]cyclohepten-5-one, respectively. The resultant alcohols were treated with perchloric acid to form the corresponding perchlorate salts, which were then reacted with ethylenediamine to afford the required H1 and H2 host compounds. Yields were 95 ad 52% for this final step in each case. An investigation of the conformations, both from experiment (using single crystal X-ray diffractometry (SCXRD) on the apohost compound) and computational calculations was undertaken. Unfortunately, H1 always crystallized out as a powder unless this host compound formed a complex with a guest species, and so could not be subjected to SCXRD analysis as apohost alone. However, a single crystal structure for apohost H2 was successfully obtained and compared with computational data from a previous investigation. It was observed that the conformation of apohost H2 compared favourably with that of the lowest energy conformer from that work. In single solvent recrystallization experiments with o-, m-, p-xylene (o-Xy, m-Xy, p-Xy) and ethylbenzene (EB), both H1 and H2 formed complexes with only one of the four guest species, namely p-Xy and o-Xy, respectively. The host:guest (H:G) ratios were 1:1 for both of these complexes. In the equimolar guest/guest competition experiments, inclusion complexes only formed when p-Xy or o-Xy, respectively, were present in the mixtures; if p-Xy (for experiments with H1) or o-Xy (H2) was absent from these mixtures, only apohost was recovered from the glass vessels. Three selectivity profiles were constructed for each of these host compounds, in which each one was recrystallized from binary mixed guests in various proportions. These demonstrated an overwhelming preference of H1 for p-Xy and H2 for o-Xy, which concurred with the results from the equimolar experiments. Thermal analysis using H1∙p-Xy revealed that this complex was unstable at ambient conditions, while SCXRD explained this observation: this complex may be defined as a true clathrate since no host‧‧‧guest interactions were identified at all, and the guest was retained in the complex by means of steric factors alone. Furthermore, the guest molecules resided in wide open channels that may have facilitated the guest release process. H2∙o-Xy, on the other hand, was stable at room temperature, and the guest release event only commenced at 69.7 °C (Ton). This too was explained by SCXRD analyses in that interactions between host and guest species were observed in this case. Additionally, the guest molecules were housed in discrete cages, which made their escape more challenging compared with p-Xy in H1∙p-Xy. It was concluded that, in this guest series, both of the host compounds would be effective as separatory tools employing host-guest chemistry protocols due to their remarkable selectivities for p-Xy (H1) and o-Xy (H2). , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: Healthcare services within a hospital setting are the basic aspects for the success of service delivery and staff performance in this regard. The paramount component of human resources makes a positive contribution to a healthcare system. Recently, it has been recognised that the performance of healthcare personnel ought to be a key factor for a sustainable performance system. Nevertheless, it is generally known that healthcare workers fail to accomplish the anticipated outcomes of health interventions. This concept leads to the research question: Why is the public sector known for poor service delivery and poor performance? This study aims to determine the factors that impact on the health worker’s performance in a tertiary hospital in South-Africa. A framework will be carefully constructed and cautiously implemented to improve and develop the performance of healthcare workers in this hospital. The vast scope and population involved in this study make a quantitative research approach most suitable, along with a non-probability purposive sampling method. A survey method using an electronic questionnaire that was circulated via a web survey, and a paper-based questionnaire that was distributed within the hospital were used to obtain a diverse perception of the healthcare workers. Data analysis included determining factors, group differences and correlations using the SPSS-27 program. The target population included all healthcare workers in the tertiary hospital – from junior employees to senior management level staff. Statistical data analysis collected for this study revealed four major factors (politics-related resources, resource, training and socioeconomic) that play a major role in the trends of performance culture at the selected tertiary hospital. These results lead to the understanding that the hospital is currently experiencing inadequate human resources management components such as recognition of employees who perform above expectations; execution of a performance appraisal system; lack in implementing the annual salary increase; unfavourable working conditions (lack of resources); troublesome management skills, and insufficient feedback on performance outcomes. These features are directly associated with the quality and degree of the performance of healthcare personnel. Based on the results, a management framework was proposed. The framework consists of activities that will improve the healthcare profession; strengthen expertise and knowledge; develop management skills; enhance knowledge through research and, ultimately, upgrade the performance of healthcare personnel. , Thesis (MPH) -- Faculty of Health Sciences, Public Health, 2021

- Description: Maize (Zea mays L) is an essential food grain crop in South Africa and is mainly grown under rainfed conditions by small-scale farmers. Quality Protein Maize (QPM) contains a higher level of two essential amino acids, tryptophan, and lysine when equated to normal maize. Therefore, the QPM in communities is a vital cereal where maize is a staple crop. Among the significant abiotic stresses that adversely affect maize productivity, such as soil fertility. Low soil pH or soil acidity results in nutrient deficiencies, as well as the toxicity of minerals such as manganese (Mn), aluminium (Al), and iron (Fe). The objectives of the study were to: (1) Characterize yellow QPM inbred lines and testcross hybrids for agro-morphological variability under optimum conditions, (2) Determine the response of QPM inbred lines and testcross hybrids to Al toxicity, and (3) Estimate the combining ability of QPM genotypes for the tolerance to Al toxicity. The laboratory assessment for tolerance to Al toxicity revealed a negative relationship between relative root growth RRG and hematoxylin staining; among the inbred lines, the genotype 8Y, 17Y, and 7Y had the highest RRG and net root growth (NRG) values and exhibited the highest tolerance to Al tolerance with the least hematoxylin staining. Inbred lines 12Y, 16Y, 19Y, 2Y, 20Y, 24Y, 30Y, 27Y, 34Y, 4Y, and 11Y were moderately tolerant. On the other hand, inbred lines 13Y, 18Y, and QSY5 had the least RRG were susceptible. Forty-four testcross hybrids were generated by crossing 22 QPM inbred lines with two open-pollinated variety (OPV) testers. These hybrids were evaluated together with five checks for different agronomic traits. The hybrids were planted in the summer season of 2017/18 and 2018/19 under rain-fed conditions 7 x 7 alpha lattice design was used. The significant variations among the genotypes for grain yield and most other agronomic traits under optimum, acidic conditions and across environments on combined analysis of variance. The hybrid was 14Y x NC (3.22 t/ha), followed by QSY5 x NC (3.02 t/ha) showed the highest yielding. The mean plant height was 226.23 cm, with ranges 197.60 to 254.85cm. The number of kernels per ear was 35, with a range from 29.45 to 40.25. Conversely, the mean ear length was 19.30 cm with a range of 17.65 to 20.95 cm, and the mean ear diameter ranged from 13,50 to 16,05 cm. The highest yielding hybrid, according to ranking, was 14Y x NC (2,93t/ha), which was ranked number 3, followed by 3Y x NC (2,83 t/ha), which was ranked number 4. Twenty-two yellow QPM inbred lines were evaluated for agro-morphological characteristics. A randomized complete block design with three replicates was used under acidic and normal soil conditions at two locations. The mean performance of inbred lines for grain yield ranged from 1.6 t/ha to 3.1 t/ha under optimum conditions, whereas it ranged from 1.1.t/ha to 1.7 t/ha under an acidic environment. The highest grain yielding genotypes under the optimum environment were 14Y, 7Y, and QSY5, while, in the acidic environment, the highest yielders were 3Y, QSY5, and 17Y. The lowest grain yielder under the optimum environment was 16Y at 1.5 t/ha, whereas 6Y, 7Y, 8Y, and 29Y were the most moderate yielders under the acidic environment. Grain yield displayed positive and significant (p<0,05) correlation with ear height (0.59), plant height (0.55), leaf length (0.18), number of leaves (0.37), number of ears per plot (0,54), number of kernels per row, number of rows per ear and thousand kernel weight. Combined ANOVA revealed that the environment effect was significant for all traits except the number of rows per ear and the number of ears in both environments. A total of 71 genotypes (22 inbred lines, forty-four single crosses, and five checks) were evaluated using a 7 x 7 alpha lattice design with two replications in combining ability. Across environments, the analysis showed a mean grain yield record of hybrids that ranged from 1.78 t/ha to 3.42 t/ha. Combined analysis showed only about 4 percent of the 44 hybrids had better grain yield than hybrid checks, whereas about 11 percent of the 44 hybrids had higher grain yield than two of the five hybrid checks. The highest yielding hybrid was 14Y x NC followed by QSY5 x NC. The Mid-parent heterosis (MPH) for grain yield ranged from -32.70 for 11YxObat to 16.50 percent for 14YxNC among the top-yielding genotypes. The highest positive mid-parent heterosis (MPH) for grain yield was observed in hybrid 14YxNC followed by QSY9xNC, QSY5xOBAT, 3YxNC, 13YxNC and 4YxOBAT, while the remaining hybrids exhibited negative estimates. Inbred lines' proportional contributions to the total variances were much higher than the testers for all traits. Whereas the inbred lines' proportional contribution was lower than the interaction of line x tester except on the number of ears which displayed the highest estimates of variances due to SCA effects, significant variation was observed. The GCA effects on grain yield in both environments generally showed no significant difference among inbred lines except for inbred lines such as QSY5 and 34Y but were positive. The selected crosses showed significant SCA effects in a few agronomic yield-related traits in the combined analysis. Among the hybrids, the only crosses that showed significant and positive SCA effects for grain yield were 25YxNC under optimum and 34YxObat under acidic environment. The inbred lines were assessed for tolerance to Al toxicity under laboratory conditions. Overall, the study identified soil acidity tolerant QPM inbred lines with an excellent combining ability for high-yielding QPM test hybrids, grain yield, and related traits. , Thesis (MSc) (Agriculture, Crop Science) -- University of Fort Hare, 2021

The objectives of the study were to: (1) Characterize yellow QPM inbred lines and testcross hybrids for agro-morphological variability under optimum conditions, (2) Determine the response of QPM inbred lines and testcross hybrids to Al toxicity, and (3) Estimate the combining ability of QPM genotypes for the tolerance to Al toxicity. The laboratory assessment for tolerance to Al toxicity revealed a negative relationship between relative root growth RRG and hematoxylin staining; among the inbred lines, the genotype 8Y, 17Y, and 7Y had the highest RRG and net root growth (NRG) values and exhibited the highest tolerance to Al tolerance with the least hematoxylin staining. Inbred lines 12Y, 16Y, 19Y, 2Y, 20Y, 24Y, 30Y, 27Y, 34Y, 4Y, and 11Y were moderately tolerant. On the other hand, inbred lines 13Y, 18Y, and QSY5 had the least RRG were susceptible. Forty-four testcross hybrids were generated by crossing 22 QPM inbred lines with two open-pollinated variety (OPV) testers. These hybrids were evaluated together with five checks for different agronomic traits. The hybrids were planted in the summer season of 2017/18 and 2018/19 under rain-fed conditions 7 x 7 alpha lattice design was used. The significant variations among the genotypes for grain yield and most other agronomic traits under optimum, acidic conditions and across environments on combined analysis of variance. The hybrid was 14Y x NC (3.22 t/ha), followed by QSY5 x NC (3.02 t/ha) showed the highest yielding. The mean plant height was 226.23 cm, with ranges 197.60 to 254.85cm. The number of kernels per ear was 35, with a range from 29.45 to 40.25. Conversely, the mean ear length was 19.30 cm with a range of 17.65 to 20.95 cm, and the mean ear diameter ranged from 13,50 to 16,05 cm. The highest yielding hybrid, according to ranking, was 14Y x NC (2,93t/ha), which was ranked number 3, followed by 3Y x NC (2,83 t/ha), which was ranked number 4. Twenty-two yellow QPM inbred lines were evaluated for agro-morphological characteristics. A randomized complete block design with three replicates was used under acidic and normal soil conditions at two locations. The mean performance of inbred lines for grain yield ranged from 1.6 t/ha to 3.1 t/ha under optimum conditions, whereas it ranged from 1.1.t/ha to 1.7 t/ha under an acidic environment. The highest grain yielding genotypes under the optimum environment were 14Y, 7Y, and QSY5, while, in the acidic environment, the highest yielders were 3Y, QSY5, and 17Y. The lowest grain yielder under the optimum environment was 16Y at 1.5 t/ha, whereas 6Y, 7Y, 8Y, and 29Y were the most moderate yielders under the acidic environment. Grain yield displayed positive and significant (p<0,05) correlation with ear height (0.59), plant height (0.55), leaf length (0.18), number of leaves (0.37), number of ears per plot (0,54), number of kernels per row, number of rows per ear and thousand kernel weight. Combined ANOVA revealed that the environment effect was significant for all traits except the number of rows per ear and the number of ears in both environments. A total of 71 genotypes (22 inbred lines, forty-four single crosses, and five checks) were evaluated using a 7 x 7 alpha lattice design with two replications in combining ability. Across environments, the analysis showed a mean grain yield record of hybrids that ranged from 1.78 t/ha to 3.42 t/ha. Combined analysis showed only about 4 percent of the 44 hybrids had better grain yield than hybrid checks, whereas about 11 percent of the 44 hybrids had higher grain yield than two of the five hybrid checks. The highest yielding hybrid was 14Y x NC followed by QSY5 x NC. The Mid-parent heterosis (MPH) for grain yield ranged from -32.70 for 11YxObat to 16.50 percent for 14YxNC among the top-yielding genotypes. The highest positive mid-parent heterosis (MPH) for grain yield was observed in hybrid 14YxNC followed by QSY9xNC, QSY5xOBAT, 3YxNC, 13YxNC and 4YxOBAT, while the remaining hybrids exhibited negative estimates. Inbred lines' proportional contributions to the total variances were much higher than the testers for all traits. Whereas the inbred lines' proportional contribution was lower than the interaction of line x tester except on the number of ears which displayed the highest estimates of variances due to SCA effects, significant variation was observed. The GCA effects on grain yield in both environments generally showed no significant difference among inbred lines except for inbred lines such as QSY5 and 34Y but were positive. The selected crosses showed significant SCA effects in a few agronomic yield-related traits in the combined analysis. Among the hybrids, the only crosses that showed significant and positive SCA effects for grain yield were 25YxNC under optimum and 34YxObat under acidic environment. The inbred lines were assessed for tolerance to Al toxicity under laboratory conditions. Overall, the study identified soil acidity tolerant QPM inbred lines with an excellent combining ability for high-yielding QPM test hybrids, grain yield, and related traits. , Thesis (MSc) (Agriculture, Crop Science) -- University of Fort Hare, 2021

- Description: This half-thesis reports on an ethnographic investigation of the implementation of the Bilingual-Bicultural Approach for educating Deaf learners, focusing on South African Sign Language (SASL) teaching at the Further Education and Training (FET) level in a South African School for the Deaf in the Eastern Cape. The investigation occurs within the context of the introduction, in 2015, of the SASL Curriculum and Assessment Policy Statement (CAPS) by the Department of Basic Education (DBE). The SASL CAPS introduces an approach to teaching the Deaf known as the Bilingual-Bicultural Approach. This is an approach in which natural sign language (such as SASL) is taught first and used to learn a spoken language such as English for reading and writing. Previous research on a contrastive analysis of South African English and SASL reveals that SASL is a Topic-Comment language. It is sometimes Object-Subject-Verb (OSV) or Subject-Object-Verb (SOV) while the word order of South African English is Subject-Verb-Object (SVO). Semi-structured interviews of hearing and Deaf participants reveal serious tensions between the staff and the hearing staff because Deaf culture is not adhered to by some of the hearing staff. These tensions have a negative impact on the culture of learning and teaching at the school. Observations of four lessons at an FET class taught by an SASL FET teacher show that in her teaching, SASL syntax is used in keeping with the principles of the Bilingual-Bicultural Approach. However, her signing is accompanied by unvoiced spoken language due to the influence of a previously used approach called Total Communication (TC). One of the learners, Lulu, who contributes considerably more often than other learners in the lesson, also shows the same influence of TC. Other learners are either withdrawn or copy signs from Lulu. The study concludes with the recommendation that SASL be used for initiating newcomers to school as opposed to Signed English because research in bilingualism suggests that second language learners need one natural language established first before attempting to learn a second language. Teachers are recommended to immerse themselves into Deaf culture to acquire fluency. Comments from some participants suggest that teachers require vigorous training in the Bilingual-Bicultural Approach on a continuous basis. , Thesis (MA) -- Faculty of Humanities, Linguistics and Applied Languages Studies, 2021

- Description: The main objective of the study was to investigate the determinants of the currency deposit ratio of South Africa. The stability of the demand for money has been a recurring area of interest of empirical research on the South African economy. Underlying this interest in the behavior of money demand is the potential role of movement in monetary aggregates as indicators of future developments in inflation. Specifically, if a stable relationship exists between the demand for money and its determinants, changes in the money supply can provide useful information in the longer terms. While there has been considerable empirical research on estimating the money demand function for many less developed countries (LDCs), the currency demand function has been largely ignored. The study used secondary data sourced from the South African Reserve Bank, Statistics South Africa and Quantec. It also used annual data from 2000 to 2018 with an autoregressive distributed lag (ARDL) technique used for regression purposes. The study opted for this model because the variables were a mixture of me (0) and me (1). The empirical results show that income had a positive relationship with currency deposit ratio. In other words, when income increases, the amount of currency in circulation increases relative to deposits. Results show that there is a negative relationship between inflation and currency demand ratio. The SARB has to monitor changes in income in order to keep pace with the demand for cash. They must also use other monetary policy operational variables such as M3 to ensure that there is a match between income and money demand and money supply. , Thesis (MCom) -- Faculty of Management and Commerce, 2020
