- Description: Cicadas have been shown to be useful organisms for examining the effects of distribution, plant association and geographical barriers on gene flow between populations. The cicadas of the Platypleura stridula species complex are restricted to the biologically diverse Cape Floristic Region (CFR) of South Africa. They are thus an excellent study group for elucidating the mechanisms by which hemipteran diversity is generated and maintained in the CFR. Phylogeographical analysis of this species complex using mitochondrial DNA Cytochrome Oxidase I (COI) and ribosomal 16S sequence data, coupled with preliminary morphological and acoustic data, resolves six clades, each of which has specific host-plant associations and distinct geographical ranges. The phylogeographical structure implies simultaneous or near-simultaneous radiation events, coupled with shifts in host-plant associations. When calibrated using published COI and 16S substitution rates typical for related insects, these lineages date back to the late Pliocene - early Pleistocene, coincident with vegetation change, altered drainage patterns and accelerated erosion in response to neotectonic crustal uplift and cyclic Pleistocene climate change, and glaciation-associated changes in climate and sea level.

- Description: This study stems from my experiences as a child who grew up playing herd boys’ musical instruments from Venda, such as the tshipotoliyo (ocarina), and tshitiringo (flute). Importantly it also builds on my time working at the International Library of African Music (ILAM,) where the aforementioned instruments, as well as the dende (musical bow) and tshizambi (Vhavenda and Vatsonga mouth bow), are displayed in transparent glass cubicles with a note, “Do not touch, they are fragile”. This phrase is painfully apt because, as a musician, I have observed a decline in the availability and performance of these musical instruments. The truth is that, other than at ILAM, these instruments are hardly in circulation, let alone being performed. This fact ignited my interest in relearning some of the musical instruments I used to play and make while herding cows in Giyani. In the context of trends such as modernisation, rural–urban migration, and globalisation, I document my experiences as a musical-instrument maker, teacher, and performer in revitalising dende, tshipotoliyo, tshitiringo, and tshizambi through classroom practice, using Rhodes music students, instrument-making workshops, performances, and community collaborations as inspiration. I propose the development of crafting skills as a medium for revitalising and sustaining these musical instruments which serve as important identity markers of the Vhavenda people. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2023

The development of biological tools to aid in the genetic investigation of the black (Diceros bicornis) and white (Ceratotherium simum) rhinoceros mitochondrial genomes

- Description: The black (Diceros bicornis) and white (Ceratotherium simum) rhinoceros are found in South Africa. A decline in the populations of these species has resulted due to human activities such as habitat fragmentation and poaching. This has contributed to the loss of genetic diversity amongst the black and white rhinoceros. Conservation and anti-poaching efforts are needed to help maintain genetic diversity. These efforts could be improved through the development of non-invasive techniques to examine DNA from threatened animals. The aim of this research was to develop a molecular technique which would allow for the identification of the black and white rhinoceros and to develop a molecular technique which would allow for intraspecies genetic variation to be examined. DNA extractions were performed on matched faecal and tissue samples that were collected from two regions in South Africa. Polymerase chain reaction (PCR) primer sets were designed to investigate several regions of the rhinoceros mitochondrial genome. PCR optimisation was completed for the target regions. Sequencing was conducted on all final PCR products. The cytochrome c oxidase subunit 1 (COIi) gene allowed for the rhinoceros family to be identified. This region was digested with the HindIII restriction enzyme, which allowed for the specific identification of either the black or white rhinoceros. A subsequent region of the cytochrome c oxidase subunit 1 (COIii) as well as the D-loop, hypervariable regions (HV1 and HV2), cytochrome b (cytb) and 16s rRNA regions were investigated. These regions displayed potential for establishing geographic origin for black rhinoceros samples, whereas the D-loop and HV2 show potential for the white rhinoceros. The white rhinoceros displayed sequence variation in the HV2 and cytb region, while variation was observed in the COIi and HV1 for the black rhinoceros. All investigated target regions allowed for the rhinoceros family to be identified. The COI (COIi and COIii), HV2 and cytb regions allowed for the subspecies of rhinoceros to be identified, however the D-loop was not able to identify the white rhinoceros species. The 16s rRNA and HV1 regions allowed for the correct subspecies of rhinoceros to be identified, however as the primers were only compatible for the black rhinoceros therefore a subsequent investigation is required for the white rhinoceros. The establishment of this novel PCR based technique to identify white and black rhinoceros will allow for efficient species identification in wildlife forensic cases. A biological method was established to study intraspecies variation for the white and black rhinoceros; however the investigated target regions did not yield sufficient genetic variation. The core techniques developed in this study will be valuable for future studies that wish to investigate genetic variation in mammal species.

Tracey, 1989) have influenced and contributed to the work of ethnomusicologists, musicologists and composers. Further this research evaluates the impact on subsequent publications by other scholars of Tracey's technical analysis of mbira music. Organizing and indexing Andrew Tracey's field collection in the ILAM archive gave direct knowledge of the scope of his work. The thesis consists of six chapters. The first chapter contains a general introduction to the thesis and outlines the goals of the research. Chapter Two presents a biographical sketch of Andrew Tracey. A general introduction to the lamellophone (mbira) family of musical instruments in Zimbabwe and elsewhere in Africa is presented in Chapter Three, which also addresses the social function of lamellophone music. Chapter Four gives a summary of Andrew Tracey’s research on the Shona mbira (his publications, recordings, films etc), and it analyzes his theory - “The system of the mbira” - in which he defines the form and structure of mbira music. Chapter Five examines the impact of Andrew Tracey’s research and publications on mbira music to subsequent scholarship and makes an analysis and evaluation of the significance of his contribution to the body of knowledge of the instrument and its music. In addition I relate my personal experiences with mbira music as a Shona person and mbira player and give my opinions on Tracey’s and subsequent scholars’ theories on mbira music. Chapter Six concludes with a summary of outcomes of this research. Basing on the analyses of presented data, it is deduced that, despite a few shortcomings, Andrew Tracey’s research on mbira music is crucial for it laid the groundwork for subsequent mbira scholarship.

- Description: With our contemporary biota under increasing threat of extinction, it is of interest to understand where, why and how biological diversity is generated. If focussed on appropriate taxa, phylogeographic and phylogenetic studies can assist in the identification of both places and processes central to the origin and maintenance of biological diversity. It is explained why southern Africa presents a perfect test-bed for exploring such mechanisms of diversification and why cicadas (Hemiptera: Cicadidae) have proved very suitable tools for studies of historical biogeography. This study then exemplifies these points by providing the first large-scale investigation of the historical biogeography of the tribe Platypleurini Schmidt, 1918, with emphasis on the genus Platypleura Amyot & Seville, 1843 in southern Africa. Standard methods of DNA sequencing provided data from portions of the mitochondrial small subunit ribosomal 16S RNA (16S) and cytochrome oxidase subunits I (COI) and II (COII); and the nuclear elongation factor 1 alpha (EF-1α) from 400 ethanol-preserved specimens. These data were analysed using standard phylogenetic methods and a time scale of diversification was estimated using a Bayesian framework and both fossil data and DNA substitution rates. The results showed that the tribe is too recent to be of Gondwanan origin. The lack of monophyly of the genera represented in both Asia and Africa showed that the tribe needs formal taxonomic revision. Diversification of the African platypleurine genera coincides with aridification in the early Oligocene. Dispersal of Asian platypleurine taxa coincides with the meeting of Africa and Eurasia in the mid-Oligocene. Two radiations within African Platypleura are hypothesised; one distributed over most of sub-Saharan Africa and the second restricted to southern Africa, with clades restricted within regional biomes. Within each of the three focal biomes, cryptic taxonomic diversity was confirmed, suggesting that, even in relatively well understood groups such as the southern African platypleurine cicadas, molecular data can identify further diversity. Although each focal taxon was restricted to non-overlapping biomes, comparison of the three biomes highlighted interactions between palaeoclimates and fixed landscape features (coastal topography, river catchments and escarpments) as causative agents of vicariance, dispersal, extinction and diversification of these volant insects. The results of using co-distributed species for comparative study cautions against making inferences based on single-taxon datasets and highlights the need to use many, evolutionarily independent taxa when identifying mechanisms of diversification. The dating analyses imply that within-species lineage diversification occurred overwhelmingly within the Pleistocene, a trend that is being increasingly recognised in print for other biota. Some caveats about using phylogenetic approaches to estimate ancestral areas are illustrated. Several recommendations are made regarding additional taxa and data sources for understanding the origin and maintenance of biological diversity.

- Description: Contemporarily, one of the major business demands is to extensively understand the impact of technology on the major business strategies and practices. Technologicalship marketing, a concept investigated in this study, emanates from a symbiosis of technology and relationship marketing. Per se, a prevalent area of debate pertains to whether technology promotes or constrains relationships. Outstandingly, this study pursued the technologicalship marketing concept, a new and vital 21st century suggestion in literature (Zineldin, 2000:16). Secondly, against the scarcity of empirical studies in mass marketing environments, the study at hand focused on retail banking client relationships. Lastly, the proposed meta-construct hypothetical model is an essential relationship marketing instrument. The proposed model consists of four major relationship marketing construct categories, namely, personal contact, customer retention, customer switching and relational exchange. At the hand of these constructs, the research primarily aimed to determine the impact of technology on client relationships in e-banking with the focus of closing the gap prevalent in literature on whether technology constraints or supports relationship marketing. The study focused on retail banking client relationships of the four major commercial banks in East London, Eastern Cape, South Africa. A survey was conducted of a sample of 200 clients selected using the convenience sampling method. The study hypothesised that technology is resulting in more transactional than relationship marketing in retail banking by constraining social constructions, customer retention and relational exchange, whilst, promoting customer switching mobility. Through the GLM regression analysis method, findings of the study established that technology was to a larger extent supporting relationship marketing. However, it is envisaged that technology is resulting in the disappearance of human contact which is a critical aspect of relationships. Conclusively, the researcher recommended that the only plausible strategy is to endeavour to integrate the human aspect at self-service podiums e.g. mounting of staff at ATM points, which most banks have been doing.

- Description: In this study white-rot fungi were investigated for their efficiency at distillery wastewater remediation and the production of laccase as a valuable by-product. Distillery wastewaters are high in organic load and low in pH. The presence of phenolic compounds can lead to extremely colour-rich wastewaters and can be toxic to microorganisms. The presence of the inorganic ions may also affect biological treatment. White-rot fungi are unique among eukaryotic or prokaryotic microbes in possessing powerful oxidative enzyme systems that can degrade lignin to carbon dioxide. These ligninolytic enzymes, such as lignin peroxidase, manganese peroxidase and laccase, are capable of degrading a vast range of toxic, recalcitrant environmental pollutants and this makes the white-rot fungi strong candidates for the bioremediation of polluted soils and waters. The laccase enzyme alone has shown remediation potential in wastewaters such as beer production effluent, olive mill wastewater, alcohol distillery wastes, dye-containing wastewaters from the textile industry as well as wastewaters from the paper and pulp industry. It has been shown to be capable of remediating soils and waters polluted with chlorinated phenolic compounds, polyaromatic hydrocarbons, nitrosubstituted compounds and fungicides, herbicides and insecticides.

- Description: Geographic Information System technology today allows for the rapid analysis of vast amounts of spatial and non-spatial data. The power of a GIS can only be effected with the rapid collection of accurate input data. This is particularly true in the case of the South African National Working for Water (WFW) Programme where large volumes of spatial data on alien vegetation infestations are captured throughout the country. Alien vegetation clearing contracts cannot be generated, for WFW, without this data, so that the accurate capture of such data is crucial to the success of the programme. Mapping Invasive Alien Plant (IAP) data within WFW is a perennial problem (Coetzee, pers com, 2002), because not enough mapping is being done to meet the annual requirements of the programme in the various provinces. This is re-iterated by Richardson, 2004, who states that there is a shortage of accurate data on IAP abundance in South Africa. Therefore there is a need to investigate alternate methods of data capture; such as remote sensing, whilst working within the existing WFW data capture standards. The aim of this research was to investigate the use of Landsat ETM imagery as a data capture source for mapping alien vegetation for the WFW Programme in terms of their approved mapping methods, for both automated and manual classification techniques. The automated and manual classification results were compared to control data captured by differential Global Positioning Systems (DGPS). The research tested the various methods of data capture using Landsat ETM images over a range of study sites of varying complexity: a simple grassland area, a medium complexity grassy fynbos site and a complicated indigenous forest site. An important component of the research was to develop a mapping (classification) Ranking System based upon variables identified by WFW as fundamental in data capture decision making: spatial and positional accuracy, time constraints and cost constraints for three typical alien invaded areas. The mapping Ranking System compared the results of the various mapping methods for each factor for the study sites against each other. This provided an indication of which mapping method is the most efficient or suitable for a particular area.

They have been fully characterized by elemental analysis and spectroscopic techniques (IR,1H and 13C NMR, and mass-spectra). The single crystal structure of the benzoyl derivative acylpyrazolone Schiff bases have been obtained and analyzed by X-ray crystallography technique. Solid state X-ray diffraction revealed a keto tautomer Schiff base in solid state. Mn(II), Co(II), Ni(II) and Cu(II) complexes with the Schiff bases have been synthesized and characterized by elemental analysis, IR and UV-VIS spectroscopy, magnetic susceptibility measurements, and thermal studies (TGA and DTG). An octahedral geometry around the transition metal ion, consisting of two bidentate Schiff base ligands bonding through the azometine nitrogen and ketonic oxygen have been proposed based on careful interpretation of available analytical and spectroscopic characterization results. Two water molecules as ligands complete the octahedral geometry in all cases. Using the invitro disc diffusion method for screening synthesized compounds against selected gram positive and gram negative bacterial at 40 mg/mL, and the DPPH free radical scavenging methods at 0.50, 0.25 and 0.13 mg/mL, the synthesized Schiff base and metal complexes showed varying biological activities. 4-benzoyl-3-methyl-1-phenyl-2-pyrazolin-5-one sul29 fanilamide showed more activity generally, exhibiting a broad spectrum activity against all selected bacterial in some cases. Mn(II), Co(II) and Ni(II) complexes of sulfanilamide Schiff base with the acetylpyrazolone derivative 4-acetyl-3-methyl-1-phenyl-2-pyrazolin-5-one sulfanilamide, exhibited a stronger and very good DPPH radical scavenging activity as good as ascorbic acid on comparing, but not with Cu(II). As such they could be important antitumour candidates.

- Description: Analysis of pan-Africanism in French African literature: case study of The Suns of independences by Ahmadou Kourouma. (L’analyse du Panafricanisme dans la littérature africaine d’expression française : étude des Soleils des Indépendances d’Ahmadou Kourouma) This study seeks to analyse the concept of pan-Africanism in French African Literature as depicted in The Suns of independences by Ahmadou Kourouma. The theme as well as the plot of the novel are both part of the post-colonial era, when African states acceded to the so-called national sovereignty. Theoretically, this was the end of colonization. Indeed, the advent of independence in Africa was, among other things, the fulfilment of one of the objectives of the pan-Africanism movement. Those objectives, according to Estanilas Ngodi (2003:6), were to promote the well-being as well as the unity of African people and those of African descendants around the world; to ensure equal civic rights for African people; to ensure the total abolition of all forms of racial discrimination; and to demand a self-determination and genuine independence of and for African’s people and states. To understand this challenging concept of pan-Africanism, we will draw inspiration from the studies of Edward Wilmot Blyden (1832-1912) who defined it as emerging a distinctive African personality: It is accepted in this study that the manner in and the extent to which the concept of pan-Africanism will be analysed should not be confused with other concepts such as Negroism or Negritude. The concern of asserting African history and identity by African people is justified by the fact that for centuries the philosophical and anthropological Eurocentric trend that Africans and their cultures and knowledge had no value. For this purpose, Trevor Roper (1963:871) asserted: “Perhaps in the future, there will be some African history, but at present, there is none; only the history of Europeans in Africa. The rest is darkness…and darkness is not a subject of history…” This denial of African history and civilization was, according to Europeans, the reason for the slave trade and colonization, and the development of pan-Africanism was the reaction or resistance against these views. That is the reason why, in the novel (The Suns of 4 independences), Kourouma depicts the concept of pan-Africanism and reveals the need for African people to assert themselves in humanity as being equal to all other races. Indeed, the advent of independence in Africa was an opportunity for Africans to regain their pre-colonial roots. Because it raised hopes and expectations to see Africa being led by its own sons. Unfortunately, independences have become a missed rendezvous or a disappointment for Africans. This argument is confirmed by the metaphor of Fama, a traditional king in the post-independence Africa: find himself “dried and undressed by colonization and Independences” (p.116). Broadly speaking, Kourouma interrogates the evolution of African societies in the light of pan-Africanism and denounces political, economic, and social issues that are affecting Africa in the post-colonial era. These issues include dictatorship, mismanagement, corruption, poverty, and the challenge of regaining African personality from colonial influence. What differentiates my study from the previous research is that I seek to investigate to which extent Kourouma portrays the failure of African society in the light of pan-Africanism before and after the colonialist era, and the impact of this failure upon the establishment of the pan-Africanist vision in Africa. Little attention has been given to the analysis of this novel (The Suns of independences) in this perspective. Kourouma is an Ivorian writer. In 1970, he published his first novel (The Suns of Independences) which is considered as a masterpiece in French African Literature and which many critics have classified it as one of the founding works in African Literature. In this study, in accordance with the novel above-mentioned I have considered three different aspects of pan-Africanism. Firstly, I described pan-Africanism as the search for the dignity of black people. Secondly, I examined it as the desire of regaining or rebuilding the African unity (African states without colonial borders). Thirdly, I analysed it as the return of African people to their history, their origin, and their cultural identity, in short, the return of Africa to its original state before the slave trade and colonization. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

- Description: Analysis of pan-Africanism in French African literature: case study of The Suns of independences by Ahmadou Kourouma. (L’analyse du Panafricanisme dans la littérature africaine d’expression française : étude des Soleils des Indépendances d’Ahmadou Kourouma) This study seeks to analyse the concept of pan-Africanism in French African Literature as depicted in The Suns of independences by Ahmadou Kourouma. The theme as well as the plot of the novel are both part of the post-colonial era, when African states acceded to the so-called national sovereignty. Theoretically, this was the end of colonization. Indeed, the advent of independence in Africa was, among other things, the fulfilment of one of the objectives of the pan-Africanism movement. Those objectives, according to Estanilas Ngodi (2003:6), were to promote the well-being as well as the unity of African people and those of African descendants around the world; to ensure equal civic rights for African people; to ensure the total abolition of all forms of racial discrimination; and to demand a self-determination and genuine independence of and for African’s people and states. To understand this challenging concept of pan-Africanism, we will draw inspiration from the studies of Edward Wilmot Blyden (1832-1912) who defined it as emerging a distinctive African personality: It is accepted in this study that the manner in and the extent to which the concept of pan-Africanism will be analysed should not be confused with other concepts such as Negroism or Negritude. The concern of asserting African history and identity by African people is justified by the fact that for centuries the philosophical and anthropological Eurocentric trend that Africans and their cultures and knowledge had no value. For this purpose, Trevor Roper (1963:871) asserted: “Perhaps in the future, there will be some African history, but at present, there is none; only the history of Europeans in Africa. The rest is darkness…and darkness is not a subject of history…” This denial of African history and civilization was, according to Europeans, the reason for the slave trade and colonization, and the development of pan-Africanism was the reaction or resistance against these views. That is the reason why, in the novel (The Suns of 4 independences), Kourouma depicts the concept of pan-Africanism and reveals the need for African people to assert themselves in humanity as being equal to all other races. Indeed, the advent of independence in Africa was an opportunity for Africans to regain their pre-colonial roots. Because it raised hopes and expectations to see Africa being led by its own sons. Unfortunately, independences have become a missed rendezvous or a disappointment for Africans. This argument is confirmed by the metaphor of Fama, a traditional king in the post-independence Africa: find himself “dried and undressed by colonization and Independences” (p.116). Broadly speaking, Kourouma interrogates the evolution of African societies in the light of pan-Africanism and denounces political, economic, and social issues that are affecting Africa in the post-colonial era. These issues include dictatorship, mismanagement, corruption, poverty, and the challenge of regaining African personality from colonial influence. What differentiates my study from the previous research is that I seek to investigate to which extent Kourouma portrays the failure of African society in the light of pan-Africanism before and after the colonialist era, and the impact of this failure upon the establishment of the pan-Africanist vision in Africa.
