- Description: Desertification is the degradation of arid ecosystems that result in the loss of biodiversity. Piospheres are areas of local degradation around a central point due to overgrazing and increased herbivore presence. There is a paucity of information regarding the effect of localised degradation on arthropods and insectivorous birds. Both of these organisms play crucial roles in ecosystem functioning and stability and can be used as models to study ecosystem functioning. I investigated the effect of piospheres on arthropods and birds in the Eastern Cape province of South Africa. I found that the abundance and diversity of arthropods were significantly reduced inside the piospheres due to the lack of vegetation. Termites were a group specifically negatively impacted by piospheres, with a significant reduction in their presence inside the piosphere. The family composition of arthropods also changed inside and outside the piospheres, with Caelifera, Diptera and Formicidae being the most dominant groups. The diversity of birds was also significantly reduced due to the degradation inside the piospheres. Looking at insectivorous birds, I found that the reduction in both vegetation and arthropod prey availability resulted in non-random avoidance of piospheres. This shows that piospheres negatively impact both arthropods and birds. The results from my study are supported by other literature studying the effects of habitat degradation associated with desertification. Due to the similarities of degradation between piospheres and desertification I make the argument that piospheres can be studied as localised models of desertification. The decrease in vegetation and arthropod abundance and diversity was found to further impact the feeding success of insectivorous birds. Using piospheres as a model for desertification, I found that the foraging effort of birds is significantly reduced within a degraded area due to the lack of vegetation providing safety to arthropod prey species. In addition to this, the foraging efficiency of insectivorous birds is significantly reduced inside the piospheres due to the decreased arthropod abundance and diversity. This shows that inside the piospheres birds spend less time searching for insects and have fewer successful feeds. This has implications for desertification of arid environments where birds face hyperthermia. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2023

- Description: This thesis explores the communicative ecology in the Enkanini informal settlement in Makhanda, and in particular their use of mobile phones and whistles to build a sense of community. It makes the case for word-of-mouth as an integral part of the communicative ecology despite not being a technological device. It then examines the sociality that arises from the use of these devices, and how coloniality impacts on the participants’ everyday experiences. The research was conducted through telephonic in-depth interviews with participants. To corroborate some of the content drawn from interviews, I used Grocott’s Mail, Makhanda’s only independent newspaper as an archival source, as well as some of the participants’ Facebook profiles. This research argues that as a consequence of coloniality, Enkanini’s residents suffer socio-economic challenges, and thus are unable to use digital technologies as much as they might like to, to communicate with their neighbours. As a consequence, word-of-mouth is their main form of communication with one another. Whistles are the ‘low-tech’ device used for community-wide communication to alert residents of an emergency, or about a meeting or protest. My findings contest generalised claims of society moving towards a network sociality, where individuality and project-based communication is valued over more communal forms of living. They also demonstrate the ways in which coloniality shapes almost every aspect of marginalised people’s lives, making word of mouth the most significant form of communication, notwithstanding the apparent availability of digital technology. It also shows how a marginalised group uses the resources it has to pressure local government officials to provide them with the basis infrastructure they need for survival. , Thesis (MA) -- Faculty of Humanities, Journalism and Media Studies, 2021

- Description: Background: The unprecedented COVID-19 era is one that posed drastic changes and challenges to healthcare professionals and healthcare system at large. During disastrous events such as the pandemic, psychosocial stress is expected among health care professionals with the development of different copying mechanisms. It is therefore important to ensure preparedness among these individuals in the event of future pandemics. It is essentials for healthcare professionals to practice healthy dietary habits and regular physical activity which has a positive impact on the immune system by improving its response to viral and bacterial infections and supports mental health. Aim: The aim of the study was to determine dietary and lifestyle changes among healthcare professionals during the COVID-19 pandemic. Methodology: A quantitative, descriptive, and explorative research approach was followed. Data was collected through an online survey and analysed using MS Excel® version 2209, SPSS version 27, cross tabulation and Pearson’s chi-square test (p-value<0.05) The questionnaire consisted of four sections that had demographics, lifestyle, dietary and COVID-19 related questions. The study sample were Eastern Cape healthcare professionals. Results: The findings indicated that health care professionals’ dietary habits and lifestyle were negatively affected by the COVID-19 pandemic. A total of 37.5% (n=131) had indicated that their weight had increased, while 20.4% (n=71) indicated a decrease in weight during the pandemic. It is understandable that there was weight gain during the pandemic as these professionals consumed more alcohol and fast foods with less exercise. There was a high caffeine consumption and decreased sleep time, which can affect productivity, resilience and mental health. The negative impacts posed by the pandemic need to be mitigated as it has the potential to lead to non-communicable diseases and cause even more of a burden to the health system. Authorities need to work with different healthcare professionals to develop programmes relating to coping mechanisms during any state of disaster and support wellness initiatives. Dietitians should be involved in order to coordinate and promote healthy eating through regular training and education of other HCP. , Thesis (MSc) -- Faculty of Health Sciences, School of Behavioural & Lifestyle Sciences, 2023

- Description: Generally, the elders in the family are usually responsible for their families, including the care and socialisation of younger members. With the increasing number of mental illness cases being reported, not only in South Africa but the rest of the world, it is imperative to explore what the elderly understand about mental illnesses, given that they may have insights that might be useful. This study aimed to explore the perceptions of elderly members in the isiXhosa community of the Buffalo City Metropolitan Municipality in the Eastern Cape province, regarding their understanding of mental illnesses. The researcher employed an exploratory-descriptive, qualitative design and adopted Lincoln and Guba’s model of trustworthiness. Participants were recruited through the use of snowball and purposive sampling and the data was gathered through one-on-one interviews conducted with elderly isiXhosa individuals. Thematic analysis was used as a means of data analysis, by following data analysis method by Braun and Clarke. The following themes were identified during the study; Limited understanding about mental illness, varied causes of mental illness and a generationally linked understanding of mental illness. The findings reflected the participants understanding of what mental illness is and the causes of it and suggest that more research is required to understand the cultural influences on perceptions of mental illness. , Thesis (Ma) -- Faculty of Health Science, 2023

- Description: Marine macro-algae are a good source of potential primary and secondary metabolites. Phytochemicals of the samples were extracted using methanol and water. This study evaluated the phytochemical constituents, antioxidant activity and antidiabetic activity of selected red marine macro-algae sampled from Gqeberha, South Africa. The species collected were identified as Gelidium pristoides, Scinaia furcellata and Portieria tripinita using DNA barcoding. Results showed the presence of several phytochemicals such as saponins, phenols, flavonols, tannins, proanthocyanidins and flavonoids. Methanol was a more effective polyphenol extraction solvent than water. Gelidium pristoides (H2O) was observed to contain the highest phenol and proanthocyanidin content, which correlated to Gelidium pristoides (H2O) having the greatest FRAP and DPPH radical scavenging activity IC50 at 0.227. Portieria tripinita (MeOH) extract had the greatest flavonoid content. Flavonol content was high for Scinaia furcellata while the highest tannin content was observed in both H2O and MeOH extracts of Gelidium pristoides. All the selected marine macro-algae species showed concentration-dependent reducing power. The extract with the highest ABTS scavenging activity was Gelidium pristoides (MeOH) IC50 at 0.227. Portieria tripinita was the only species that showed Nitric oxide scavenging activity, with (H2O) extract showing the highest activity IC50 at 3.052. Only MeOH extracts of Gelidium pristoides and Scinaia furcellata showed very slight α-amylase inhibition, however, all extracts successfully inhibited the activity of α-glucosidase with the exception of the H2O extracts of Scinaia furcellata. All crude extracts of Gelidium pristoides, Scinaia furcellata and Portieria tripinita showed no significant/weak effect on glucose uptake and utilization by C3A cells following 24 hours of treatment, with the exception of the aqueous extracts of Scinaia furcellata at the highest concentration of 100 μg/ml. The in-vitro MTT cytotoxicity assay revealed that only MeOH extracts of Gelidium pristoides and Scinaia furcellata had a 15 significant toxic effect on C3A hepatocytes at concentrations of 100 μg/ml and 25μg/ml, respectively. Portieria tripinita aqueous extract showed cytotoxicity when evaluated using Hoechst 33342/Propidium iodide (PI) dual staining. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: Discrimination is a serious violation of human rights and it is strongly condemned by various legal instruments in South Africa. The South African Constitution (1996), Promotion of Administration Justice Act (2000) and Promotion of Equality and Prevention of Unfair Discrimination Act (2000) forbade discrimination and exclusion of pregnant learners from school. In spite of these legislative frameworks, School Governing Body (SGB) continues to exclude pregnant learners from school. SGB claimed that pregnant learners are harmful to other female learners and is becoming a significant barrier to girls’ education. Research shows that learners’ pregnancy is predominant in rural areas, apparently poses a threat to female education (Annual School Survey Report, 2010). The purpose of this dissertation is to establish that SGB lacks power to do so; however, their resistance to the law by excluding the pregnant learners from school is in conflict with the South African Constitution. This dissertation investigated an alternative instrument of legal remedy to reduce the problem of learners’ pregnancy rather than exclusion. The theoretical framework of this study is informed by Public Policy Theory (Ijeoma, 2010). Literatures and scholarly works on education law (Oosthuizen, 2015) and articles on Learners’ pregnancy shall be reviewed (Morell, Bhana & Shefer, 2012). The study followed qualitative research method which utilizes a transformative research paradigm that provides a collective voice for the participants. The data is collected through focused interview and open-ended questions, and subsequently analysed to establish that SGB lacks power to exclude a pregnant learner from school. Finally, the study reveals an alternative instrument of legal remedy to reduce the alarming number of pregnant learners rather than exclusion. , Thesis (MEd) -- Faculty of Education, 2017

- Description: Purpose: Academics and the government are placing more emphasis and importance on the role that enterprises can play in response to challenges of the environment. This study aimed to establish the relationship between green behaviours and the performance of small businesses in South Africa. Green behaviours are measured as consisting of green entrepreneurial orientation, green technology dynamism and green innovation behaviour. Conversely, performance is defined as consisting of environmental performance, objective performance and subjective performance. Design/methodology/approach: To achieve the purpose of this study, the study adopted a positivist paradigm which is motivated by the quantitative approach using a descriptive research design. Self-administered questionnaires were employed with a sample of 180 participants that were randomly selected across small businesses in the Buffalo City Metropolitan Municipality in the Eastern Cape province of South Africa. Findings/results: The major findings of the study, using simple linear regression analysis, revealed that a significant positive relationship between green entrepreneurial orientation and environmental, objective and subjective performance does exist. However, the hierarchical regression analysis results revealed that green technology dynamism and green innovation behaviour do not moderate the relationship between green entrepreneurial orientation and performance as measured by environmental, objective and subjective performance dimensions. Practical implications: Based on the findings of the study, small businesses need to develop policy related to promoting green behaviours, given that green entrepreneurial orientation has been found to be related to performance. Originality/value: The results of this study could guide small business owners and managers in the implementation of environmentally-friendly practices in an effort to reduce green economy issues and environmental problems facing the present generation. , Thesis (MCom) (Business Management) -- University of Fort Hare, 2021

Findings/results: The major findings of the study, using simple linear regression analysis, revealed that a significant positive relationship between green entrepreneurial orientation and environmental, objective and subjective performance does exist. However, the hierarchical regression analysis results revealed that green technology dynamism and green innovation behaviour do not moderate the relationship between green entrepreneurial orientation and performance as measured by environmental, objective and subjective performance dimensions. Practical implications: Based on the findings of the study, small businesses need to develop policy related to promoting green behaviours, given that green entrepreneurial orientation has been found to be related to performance. Originality/value: The results of this study could guide small business owners and managers in the implementation of environmentally-friendly practices in an effort to reduce green economy issues and environmental problems facing the present generation. , Thesis (MCom) (Business Management) -- University of Fort Hare, 2021

- Description: As top predators, seabirds occupy the upper trophic level of marine ecosystems. They are consequently important for the maintenance of ecosystem structure and function, while also possessing characteristics which are useful for identifying climate-driven changes in oceanography at all trophic levels. This important faunal group is one of the most threatened, with climate change and fisheries bycatch mortality being the primary drivers of population declines. Understanding these threats is important for the management of threatened seabird populations. One impact of climate change and variability in climate occurs through changes in prey availability. As central place foragers, breeding seabirds have trip duration constraints due to the obligation of nest duties. This makes them particularly vulnerable to changes in prey availability within their foraging ranges. The ability to adjust foraging behaviour during environmental conditions which alter prey availability is an important attribute which can contribute to breeding success. Thus, investigating for this foraging behavioural plasticity during different breeding stages provides insights into how a species is likely to be impacted by climate change. The sooty albatross population on Marion Island was studied and displayed a degree of foraging behavioural plasticity during the five-year period of pronounced climatic variability studied. Incubating birds mainly foraged in the subtropical convergence zone (STCZ), the Sub Antarctic Front (SAF) and Subtropical Front (STF) which border it, and the region north of the STF. Brooding birds mainly used the SAF and Polar Frontal Zone (PFZ). Significantly different areas were used between years during both breeding stages. This population showed a lack of consistent habitat preferences which may offer resilience to progressive climatic variability and change. Interactions of sooty albatrosses, as well as white-chinned petrels for comparative purposes, with fisheries were also assessed. The two species were compared to shed light on possible explanations for differences in seabird-fishery interactions between the species. The impact of fisheries-related mortality (bycatch) is dependent on exposure to fishing activity and attraction to fishing boats encountered while foraging. Bycatch mortality has previously been proposed as the main cause of this sooty albatross population’s decline. Exposure and 6 attraction to fishing boats was found to be lower than that of white-chinned petrels which are bycatch prone. However, the current level of attraction exhibited by this sooty albatross population may expose a significant fraction of the population to bycatch risk due to its small population size. Additionally, all fishing boats were encountered north of the STF where non breeding individuals are now known to be distributed. Thus, the impact of fisheries on this population may mainly be mediated by more bycatch prone non-breeding individuals. Overall, the relative impact of fisheries bycatch mortality is suggested to be higher than that of climatic impacts on the sooty albatross population on Marion Island. However, this study did not incorporate dietary and demographic information which would reveal whether there are nutritional differences between years that may impact on breeding success. An integrated rather than independent assessment of foraging behavioural responses to climatic variability and fishing activity is recommended for improving our understanding of current and future conservation priorities. , Thesis (MSc) -- Faculty of Science, Zoology , 2021

- Description: This is an autoethnographic and performance-based study on the correlation between indigenous and modern cultures. It discusses the influence of globalisation, modernity, and of the Chopi people migrations to Maputo, the main city of Mozambique and to gold and platinum mines in South Africa, on timbila music. Timbila is both the name of a musical instrument (xylophone) and of a cultural manifestation, practiced by the Chopi people from Mozambique. It is one of the most documented music and dance cultures in Mozambique and was proclaimed as a masterpiece of the oral and immaterial heritage of humanity by UNESCO in 2005. The oldest references by Father Andre Fernandes date from the 16th century. However, the most well-known timbila sources were written and recorded by Hugh Tracey, the founder of the International Library of African Music (ILAM), from 1940s. All these sources were based on traditional timbila music. None refers to contemporary timbila music, which is a mixture of timbila with Western musical instruments. The research is thus based on both historical and is new research to understand the role of the phenomena mentioned above to the reinterpretation of timbila music over the time. Performance based and autoethnography methods were selected because of my role as a pedagogue of the music and culture of timbila, allowing me to express my knowledge on this cultural expression. Literature review and interviews are the two procedures of data collecting employed to get an understanding of the research methods; the phenomena of modernity, globalisation and of the Chopis migration for the searching of better living conditions in Maputo and South Africa; and the approaches of different scholars who have written about timbila. The use of these methods and methodologies, allowed me to conclude that, Chopis migrations, modernity and globalisation has allowed the emergence of a modern version of timbila music; internationalisation and dissemination of this musical expression; and contributes to the extinction of traditional timbila orchestras in Zavala. Despite considerable studies on timbila music and culture, this thesis is important and pioneering, from the perspective of studying the influence of Chopis migrations, globalisation and modernity on timbila and is one of the few sources that approach the contemporary timbila music. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2022

- Description: This is a case study conducted in the Methodist Church of Southern Africa (MCSA), Grahamstown, in the Eastern Cape. Against the backdrop of identifying and conceptualising ethically oriented leadership competencies, the purpose of this study was to explore service as a leadership competency. The literature reviewed in this research underscored the importance of effective and ethical leadership, but critiqued the Westernised, individualistic orientation of the conceptualisation of service as a leadership competency. Based on a review of the literature, this study proposes that when African leaders are in leadership four components of Ubuntu are involved when they exercise service as a leadership competency. These components are collective consideration, collective compassion, community server and Ubuntu humility. The main aim of this study is to investigate if leaders display these four components when exercising service towards their followers, and if so, how, and why they do so. A conceptual framework of components of Ubuntu, which culminated in research themes and propositions, were produced from the literature chapter. A qualitative research method was adopted in this study in which eight participants were selected through convenience sampling for this case study. One minister and seven Vice-Presidents of various organisations in the Methodist Church were interviewed. Semi-structured interviews were conducted for data collection and a deductive thematic analysis approach was employed to analyse data. Also, the critical incident technique (CIT) was utilised to structure interview questions, which is best fitting to solicit complex and comprehensive data from the interviewees. In its findings, the study confirmed the presence of the four components of Ubuntu, but several delimitations and limitations are acknowledged. Nevertheless, the study has made some contribution to understanding the display of service as a leadership competency in an African context. The implications for management practice are considered and recommendations made for future research. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2022

- Description: The aim of this study was to gain an insight into perceptions of teachers on the implementation of positive learner discipline in three primary schools in the Amathole- West Education District. The study was in the interpretive paradigm and adopted a qualitative approach in the collection of data. A case study design through face-to-face interviews and document analysis related to positive discipline were used for data collection. Three schools were selected through purposive sampling. Four teachers per school participated in the study and these were purposively sampled. Data from the findings were thematically presented and analysed by scrutinizing it for commonalities. The study revealed that teachers had ample knowledge on positive learner discipline and therefore tried to implement it to the best of their abilities. The study also established that teachers perceived positive discipline as a good approach for disciplining learners. Participants were aware that positive learner discipline made learners feel and that it assisted them to improve and sustain good behaviour. Data revealed that schools used different strategies to implement positive learner discipline, such as, class rules, rewards and awards, personal relationship with learners, role model, communication with learners, point system, goal setting, hand-system and sign language, isolated area in front of the classroom, positive attention and guidelines on discipline. In contrast, the study also revealed that a minority of teachers still administered corporal punishment, which is unlawful and traditional. They also applied punitive disciplinary measures. The study concluded that the selected schools encountered various challenges on the implementation of positive learner discipline. These included undisciplined learners, limited involvement and minimal support from the Department of Education (DoE) and limited support from the School Management Team (SMT), uninformed, ignorant and rude parents, lack of parental involvement, parents using punitive measures, no proper training for teachers and parents, overcrowded classrooms and unhappy teachers. As for monitoring and support from the SMT and DoE, the study envisaged that most participants were supported by the SMT, other than the DoE. , Thesis (MEd) -- Faculty of Education, 2020

- Description: The empirical study investigates the relationship between inflation, credit markets and economic growth in the context of Brazil, Russia, India, China and South Africa (BRICS) countries. The BRICS group consists of five emerging market economies and was first coined by Jim O’Neil of Goldman Sachs in 2001 whereby initially the bloc consisted of only Brazil, Russia, India, China, South Africa joined the BRICS group in 2010. The BRICS bloc was deemed to be the top fast-growing economies that showed great potential for growth. Consequent to the 2008 global financial crisis, there has been a large change in economic thinking as policy-makers have struggled to overcome the economic misfortunes caused by the crisis. Amongst the emerging countries, the BRICS countries have in effect, established a New Development Bank to play the role of the credit facilitator the BRICS countries and other emerging countries as well. This BRICS New Development Bank was established in 2014 and already has identified and funded some projects within the BRICS countries. Moreover, the main objective of this bank is to provide credit to be utilised for infrastructure, climate change measures, as well as to ensure sustainable development. Against this backdrop, the current study investigates the role played by credit and the extent of development in credit markets on enhancing growth in the BRICS countries, particularly looking at the levels of inflation that are conducive to credit market development. The study notes that in order for credit expansion to be successful, the credit received by a country must reflect positively on a country’s economic growth. In other words, with more credit coming into a country, the expected result is that there will also be a rise in economic growth. Furthermore, seeing that inflation erodes the value of money, this credit or these funds that a country receives may not have the expected influence on growth. Therefore, the study finds it imperative to investigate the levels at which inflation allows for credit expansion to promote growth in a country. Furthermore, central banks play an important role in credit markets via the interest rate channel and the study examines the role of monetary policy in credit markets of each of the BRICS countries by looking at the inflation targeting regime as well as the absence thereof within these countries. Moreover, BRICS central banks share more or less the same goal of maintaining price stability and low inflation through various monetary policy tools. Therefore, achieving this objective will allow a central bank to gain both investor and consumer confidence which plays a role in a country’s investment rates. Moreover, inflation that is not controlled results in uncertainty which makes investors hesitant and unwilling to embark on investments. Ha, Ivanova, Ohnsorge and Unsal (2019) associate a developed financial sector with low inflation, stating that stable inflation rates eliminate uncertainty and avoids the erosion of the value of money. The current study used an Autoregressive Distributed Lag (ARDL) model to examine the linear co-integration and Non-linear Autoregressive Distributed Lag (NARDL) for the non-linear empirical analysis of the relationship between inflation, credit markets and economic growth in BRICS countries. The non-linearity of this relationship is important to study as there has been many debates on the nature of the inflation-growth relationships with some studies implying that it is positive, some say it is a negative relationship and some say it is non-linear. The annual data time series is extracted from the World Bank Indicators and the Penn State database covering the period 1960-2019. The main variables used in the study are Inflation (CPI), Credit (Domestic Credit to Private Sector) and Economic growth (GDP). The study conducted various regressions including the total of five linear regressions which were run individually for each country, the non-linear regressions consisted of three regressions for each country which were on 1) Only Inflation partitioned, (2) Only Credit partitioned and (3) both Inflation and Credit were partitioned. The partitioning of the variables is made possible by the NARDL model which allows variables to be partially decomposed into negative and positive sums to identify thresholds of variables which have various effects on other variables. The overall findings of the study suggest that although inflation exerts various effects on growth, according to this study’s results, it does not have a significant impact on credit for all the countries except for China whereby credit in general is conducive to economic growth and Brazil where growth is enhanced when credit is declining. The study revealed that generally, inflation exerts a negative impact on growth, therefore, authorities must focus on keeping inflation rates low particularly for Russia, India and South Africa as Brazil’s results suggest that rising inflation is conducive to its economic growth in the long run. According to the findings of this study, credit does not have the significant impact on growth even under different inflation thresholds. Furthermore, this does not imply that the credit channel is a futile tool for authorities, the relationship between inflation, credit and growth particularly with the hypothesis that inflation enhances credit market development and therefore growth, is not significant. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development & Tourism, 2021

- Description: The study investigated access to digitised archival collections in two selected institutions in the Eastern Cape Province, South Africa. This study is significant because it sought to generate insights on adaptability of technology in archives and library operations, and accessibility thereof. This is important for monitoring the accessibility of digitised archival collections at institutions to improve their operations and maximize the global visibility. This study adopted qualitative research methodology. The researcher followed a rigorous methodological path that began with a thorough literature review and the careful and thoughtful posing of research questions and objectives. A purposive sample was chosen from National Heritage and Cultural Studies Centre (NAHECS) and International library of African Music (ILAM) (staff members) and interviewed through face-to-face interviews. The collected data was analysed thematically. The study established that, the type of materials digitised at NAHECS and ILAM are bound books, fragile papers, photographic prints, slides, audio-visual materials,artefacts and documents such as personal letters of early travellers,missionary’s records,traders writing personal file and political parties documents. Secondly, the study established that end users of digitised materials are researchers, students, archivist, librarians, international and local community, composers, musicians, and historians. It also emerged that awareness programmes used to increase public knowledge about access to digitised content in the two study sites include conferences, social media, and television advertisements. However, there are challenges faced in providing access to digitised materials at NAHECS and ILAM. Some of these challenges include lack of funding, unavailability of resources, lack of awareness, and information insecurity. These challenges have made access to digitised archival materials difficult. Based on these findings, it is recommended that archives facilities should be well resourced and archivists be continually trained on access to digitised archival materials. , Thesis (M Bibl) -- Faculty of Social Sciences and Humanities, 2021

- Description: Maintenance of a species’ abundance and adaptive potential is partially dependent on its genetic diversity. Distinct genetic lineages within a species can differ significantly in their resistance and resilience to environmental pressure. An assessment of such differences is key to grasp the adaptive potential of a species. Physical environmental conditions are significant determinants of the distribution of species and their genetic lineages. Under climate change scenarios, the assessment of the temporal stability of the spatial distribution of genetic structure has important consequences for conservation as it offers key insights into the adaptive potential and evolutionary capacity of a species. This thesis investigated the phylogeography and reproductive isolation of Perna perna, the brown mussel. This species is an ecologically and economically important intertidal mussel on South Africa’s coastline. It was determined in 2007 that there were two distinct genetic lineages of P. perna present on South Africa’s coastline, the Eastern and Western lineage. This thesis compared mitochondrial DNA between samples collected in 2007 and samples collected in 2019 to determine differences in genetic structure of P. perna over time. This thesis further investigated the reproductive timing of the two lineages to determine if this contributes to the maintenance of the genetic structure of this species. The results show that there is a shift in the distribution of the Eastern lineage since 2007, an increase in the range of the overlap region, and there was a change in genetic diversity in the form of private haplotypes between 2007 and 2019. The lineages have unsynchronised spawning and reproductive patterns are more closely linked to changes in temperature. While the lineages have shown slight distributional changes over time, the influence of environmental conditions and the predicted changes in sea surface temperatures could see a change in future populations’ fitness and dispersal. Thus, changes in sea surface temperature could affect reproductive timing and the future genetic stability of the species. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2021

- Description: The French horn is an orchestral instrument with a rich history that spans centuries, undergoing notable transformations in its design and functionality. A short overview of this history is provided in Appendix A. Originating as a simple coil, the French horn has evolved to encompass a complex valve system, multiple harmonic series, and a diverse range of modifications tailored to players' preferences and requirements. These modifications include mutes, grips, extra keys, and even the exploration of different materials for mouthpieces. The use of plastic rims on mouthpieces, for reasons such as allergies, thermal conductivity, and tactile sensation, has already gained traction among horn players (Tuckwell, 2002). In the realm of manufacturing and technology, the concept of additive manufacturing has emerged as a promising avenue. Referred to as the next "industrial revolution” (Berman, 2012), additive manufacturing has become increasingly accessible through desktop-scale 3D printers. This technology offers a viable method for producing cost-effective musical instruments and enhancers without compromising quality (Kantaros, 2018). As evidenced by a 2018 Roundtable report from the South African Parliament, additive manufacturing aligns with the trajectory of the fourth industrial revolution, prompting governments to develop policies and strategies to harness its potential. Given the significance of additive manufacturing, a comprehensive investigation into applying these new technologies for the horn is warranted. Specifically, material choice, quality of sound, and the experience of performing on a printed mouthpiece is investigated and compared to a traditional metal mouthpiece. While the horn is comprised of many individual components, this study relates specifically to the mouthpiece. A brief appraisal of the significance of the mouthpiece will follow in the next section. , Thesis (MMus) -- Faculty of Humanities, School of Visual and Performing Arts, 2024

- Description: INTRODUCTION: Rugby union has been one of the team sports that has grown over the last few years, and the margin between success and failure for teams has become narrower as the years have gone by. The game consists of players going through different movements such as sprints and/or collisions, that vary in intensity. The demands that face schoolboy rugby players are not well understood, and the lack of research in this area leads to a potential lack of understanding of the perceptions that coaches have about the demands that schoolboys are faced with during a match. OBJECTIVE: Therefore, the purpose of this study was to determine the perceptions that the schoolboy rugby coaches had surrounding the demands that their players are faced with during a 70-minute match. There were a few secondary purposes of the study, such as determining which school, government or private, had a better understanding or perception of the demands, as well as comparing strength and conditioning coaches’ perceptions to regular coaches’ perceptions. METHODS: This was a cross-sectional, descriptive study to determine the coach’s perceptions. These perceptions were collected through an online questionnaire, which consisted of ten sections and 74 questions. The questionnaire was piloted on a subject group with different types of experience. Coaches from the top 100 schools list were contacted through their school website. RESULTS: The questionnaire had a 72% response rate: 41 responses from 51 emails. The 41 responses consisted of 23 government schools and 18 private schools, which included 11 of the top 20 rugby schools in South Africa, with most responses coming from the Eastern Cape (41.5%). Results indicated that a government school’s coaches had significantly (p<0.05) more experience than private schools’ coaches, and that they had significantly (p<0.05) better academic qualifications than private schools. However, strength and conditioning coaches had significantly (p<0.01) better academic qualifications than coach, whereas coaches had significantly (p<0.01) better coaching qualifications than strength and conditioning coaches. CONCLUSION: “Experience has been shown to be a potential reason for what is described as a good coach”. This is also another potential reason why government schools are a dominant force in schoolboy rugby in South Africa. However, this is also coupled with better qualifications showing the dual importance of both experience and education. This study has shown that coaches, within a South African cohort, overall had good general perception of the demands of school level rugby matches. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2021

- Description: Background: Globally, childhood mortality remains high with 5.3 million deaths occurring in children under the age of five years in 2018. Of these deaths, 43 000 were children from South Africa, with malnutrition being a significant risk factor contributing to disease and death. Breastfeeding has many benefits and reduces childhood mortality. Current primary health care strategies in South Africa are not having an adequate impact on breastfeeding rates, therefore appropriate messages need to be targeted at the community in order to improve breastfeeding rates. Participatory approaches have been identified as an effective tool to promote child health. Community dialogues led by skilled Early Childhood Development (ECD) mentors from the community might be key in order to improve caregivers’ knowledge, attitudes and practices (KAP) in relation to breastfeeding and Prevention of Mother to Child Transmission of HIV (PMTCT). Aim : The aim of the study was to explore the potential effects of community dialogues, led by ECD mentors, on caregivers’ knowledge, attitudes and practices (KAP) in relation to breastfeeding and prevention of mother-to-child transmission of HIV (PMTCT). Methods: Quasi-experimental design was used to compare the KAP of caregivers in relation to breastfeeding and PMTCT. Convenience sampling was used to include 63 caregivers who participated in the umbrella project (mixed-methods) and 61 caregivers who did not participate in the project. Ethics approval was obtained from the Nelson Mandela University Faculty Postgraduate Studies Committee. Participants had to provide written informed consent. A skilled interviewer used a structured questionnaire to assess the KAP of all participants. Data were captured on an Excel spreadsheet and analysed in collaboration with a statistician, who analysed the data using Microsoft Excel. Descriptive statistics were applied to numerical data, while frequency distributions were applied to categorical data. Correlations were calculated to describe the degree of relationship between two variables. Inferential statistic tests, conducted at a significance level of 0,05, were used for hypothesis testing. The t-test and analysis of variance (ANOVA) were used in tests involving mean values. Scheffé’s test was used in ANOVA to determine between which of the groups a statistically significant difference was found. Results: In the intervention group more than double the number participants (35%; n=22) had a good knowledge of breastfeeding when compared to participants (15%; n=9) in the control group. Additionally, the intervention group participants displayed better attitudes towards the RtHB (p=0.02). However, control group participants showed better knowledge towards the HIV (p=0.01). Finally, results suggest that in the intervention group, participants (33%; n=21) were more likely to have a good total KAP score in relation to breastfeeding and PMTCT when compared to participants (11%; n=7) in the control group. In the intervention group, better knowledge correlated with good practices relating to the RtHB (r=0.27). However, in the control group, positive attitudes correlated with better practices relating to HIV (r=0.29). Younger intervention group participants displayed better breastfeeding related practices (p=0.011). Additionally, younger control group participants displayed better knowledge of breastfeeding (p=0.001). Intervention group participants whose choices were influenced by their husband/ partner (p =0.016) and/ or radio/ magazines/ newspapers (p=0.004) had positive attitudes towards HIV. Control group participants whose choices were influenced by their other family members (p=0.043) and/ or clinic staff (p=0.016) had good knowledge of sharing their knowledge. Conclusions and recommendations: The intervention group displayed a better knowledge of breastfeeding as well as more desirable attitudes towards the RtHB, when compared to the control group. However, the control group displayed better knowledge of HIV, which could be due to the control group having more younger participants when compared to the intervention group. The community dialogue intervention had a positive impact on caregivers KAP relating to breastfeeding and PMTCT, which included all the different categories combined. In order to improve the Sakha Esethu intervention programme, managers need to provide guidance to the mentors on how to initiate conversations regarding HIV and discuss the stigma associated with HIV and breastfeeding. Results showed that including grandmothers and husbands or partners in the target population will benefit the intervention. Additionally, the use of radio needs to be considered especially for discussions regarding HIV. Lastly, sustainability needs to be improved due to many participants not remembering certain detail regarding topics that was discussed. , Thesis (MSc) -- Faculty of Health Sciences, 2021

- Description: The principle of justification in radiographic imaging aims to best answer a medical question while evaluating the expected benefits of radiation exposure against the probable detriment to the individual patient. The implementation of justification in radiography requires the assessment and evaluation of chest mobile radiographic requests against justification criteria, considering the underpinning principles of radiation: justification, optimisation and authorisation. Diagnostic chest mobile radiographic imaging has been part of healthcare for the last century. Medico-legal requirements by the professional registration body, the Health Professions Council of South Africa (HPCSA), identify justification as an advocated and obligatory practice among radiographers. Yet, justification remains an inconsistent practice among South African radiographers due to several challenges in the healthcare setting. The aim of this study was to investigate the experiences of radiographers regarding the justification of chest mobile radiographic examination requests in a private radiology practice in the Nelson Mandela Bay Health District (NMBHD). A qualitative, exploratory-descriptive and contextual research design was used to gain in-depth data of the experiences of South African radiographers regarding the justification of chest mobile radiographic requests. Data were gathered from the participants using unstructured, open-ended, in-depth individual interviews. Data were transcribed verbatim and coded using Tesch’s eight steps of data coding and analysis process. Two principal themes were constructed during data analysis. Theme one identified the barriers and associated affective responses related to the appropriate implementation of justification of mobile chest radiographic examinations. Theme two recognised recommendations to enhance the implementation of justification by radiographers for mobile chest radiographic examinations. The research study was governed by methods to ensure trustworthiness and ethical practices. Based on the findings of this study, four recommendations were developed to assist radiographers to establish whether a request for mobile radiographic chest examinations is appropriately justified, which can contribute to establishing a radiation safety culture in the research setting pertaining to chest mobile radiography. , Thesis (MSc) -- Faculty of Health Science, School of Clinical Care Sciences, 2023
