- Description: This study is concerned with people’s attitudes towards the Communal Areas Management Programme for Indigenous Resources (CAMPFIRE). This study is situated in Kanyemba, a ward in Mbire District, Mashonaland Central, Zimbabwe. CAMPFIRE is a community-based natural resource management programme that aims at empowering local communities to sustainably manage and benefit from wildlife and other natural resources within their confines. This study explores people’s attitudes towards development (and CAMPFIRE as a development programme) and how they perceive, engage with, and contest development. There are two subgroups living in Kanyemba: the Chikunda, which is the majority group, and the Tembo Mvura. Rooted in post-development thinking, this study highlights the nuances and ambiguities in people’s attitudes towards development. The study relies on interviews, participant observation, and archival material. The study has three guiding objectives. Firstly, I set out to explore how the Tembo Mvura and Chikunda community members living in Kanyemba perceive and interact with the CAMPFIRE programme and how their views coincide with or diverge from mainstream development discourse. The study discusses the Tembo Mvura and Chikunda definitions and descriptions of development and the two groups’ perspectives and experiences of the CAMPFIRE programme. While the Tembo Mvura have mostly negative attitudes towards CAMPFIRE, their Chikunda neighbours exude both positive and negative attitudes towards development, projecting a sense of joy and appreciation but also disillusionment with development. Secondly, I highlight how Tembo Mvura and Chikunda actively participate in and challenge the CAMPFIRE project and how these interactions can be interpreted within the framework of post-development theory. As I explore these attitudes, I portray the ambivalence evident in people’s simultaneous desire for and dismissal of development. While the people dismiss some aspects of development, they still want some development, hence the ambivalence. Finally, I explore how the residents of Kanyemba have responded to the limitations of CAMPFIRE, what alternatives to development they propose, and what role cultural, historical, economic, and environmental factors play in shaping the communities’ alternatives to development. The residents of Kanyemba have different historical and cultural backgrounds, and I highlight how these have influenced the different alternatives to development proposed by Tembo Mvura and Chikunda. In this regard, I explore the nuanced critiques of development held by residents of Kanyemba, examining how cultural and historical factors influence their selective engagement with different aspects of the CAMPFIRE initiative. This thesis contributes to post-development thinking by arguing that the ambivalence evident in people’s attitudes towards development in Kanyemba makes dismissing development more complicated than some post-development theorists suggest. The findings of the study show that people’s ambivalence towards development emanates from CAMPFIRE’s approach that strips individuals of agency, stifles their voices, and curtails democratic participation in determining their preferences and how they desire to progress. , Thesis (PhD) -- Faculty of Humanities, Political and International Studies, 2025

- Description: Walkability is an important research topic in the Global South where many people in urban settlements walk because of transport poverty. University students are a subset of the urban population in Makhanda who experience transport poverty and largely rely on walking to navigate the city. The purpose of this study is to measure and spatially analyse walkability and walking patterns in the student community of Makhanda, South Africa. This study has a specific focus on students who reside in the Rhodes University campus, Central Business District (Central), Sunnyside, and Westhill. These specific areas were chosen because, in terms of student residents, these are the most densely populated residential areas in the city, but are also the epicentre of student activity. This research intends to explore the existing walkability within these four study sites through a visual survey using common measures of walkability, digital mapping as well as student perceptions of walkability. The quantitative data collected through visual surveys, digital mapping and participatory mapping will be spatially analysed using GIS (Geographic Information Systems). Results show that walking is the main mode of transportation and students do not have affordable alternatives to walking. The Rhodes University campus is the most walkable area with Central being the second, Westhill being the third, and Sunnyside being the least walkable area. Sidewalk conditions (sidewalk presence, evenness and maintenance) and pedestrian safety and security (pedestrian crossings, crime, security features, lighting, the presence of people, and pedestrian visibility) were rated as the most important walkability factors. Additionally, the more walkable roads are mainly found within the Rhodes University campus and Sunnyside while the less walkable roads are mainly found within Central. Furthermore, the epicentre of student activity is focused on the Rhodes University campus during the week and as the week progresses, the epicentre shifts along with a shift in activity. The Rhodes University campus and Central are where students spent most of their time because the main amenities that student use are found within these areas. This research offers insights into walkability that can be directly applied to urban planning and policy-making. Planners should focus their resources on improving walkability, particularly in sidewalk conditions and pedestrian safety and security. By applying the findings of this research, planners can create more conducive, safer, and comfortable walking environments. , Thesis (MSc) -- Faculty of Science, Geography, 2025

- Description: This thesis presents observations of medium to large-scale traveling ionospheric disturbances (TIDs) originating from high latitudes, and propagating towards the equator and TIDs originating from the equator with a poleward propagation in the African-European sector during geomagnetically disturbed conditions between 2006 and 2022. 196 TID activities propagating over the African-European sector were observed, of these TID activities, 161 and 33 were observed during geomagnetic storms, and simultaneous occurrence of geomagnetic storms and solar flares, respectively. Total electron content perturbations derived from Global Navigation Satellite Systems (GNSS) observations within a latitude range of 40°S–60°N and longitude ranges of 20°-40°E representing the African-European sector were analysed based on the storm criteria of Dst ≤ -30 nT. The GNSS total electron content (TEC) data were used to obtain the two dimensional (2d) TEC perturbations. The northern hemispheric part of the African sector has limited data coverage which is visualized by a gap around 20°, where there were no data coverage can be observed in the 2d TEC maps. An important result is that large-scale TIDs (LSTIDs) and medium-scale TIDs (MSTIDs) were found to occur predominantly during the main and recovery phases of geomagnetic storms respectively, at least over the African-European sector. During the main phase of storms equatorward LSTID activity was relatively consistent across both hemispheres, with years of solar maximum, between 2013 and 2015, showing higher frequencies of events. Equatorward MSTID activity appeared less frequent overall, particularly in the southern hemisphere (SH), suggesting that equatorward LSTID activity are more prominent during the main phase of geomagnetic storms. Poleward TID activity were more predominant in the recovery phase than the main phase of geomagnetic storms. , Thesis (MSc) -- Faculty of Science, Physics and Electronics, 2025

- Description: Cytochrome P450s are a superfamily of enzymes with over 50 members involved in metabolizing 90% of xenobiotics. Among the these, families 1, 2, and 3 are responsible for approximately 80% of clinical drug metabolism. This study investigates the effect of Afrocentric missense variants on the structural dynamics of CYP2B6. Molecular dynamic simulations reveal that specific variants affect the enzyme’s flexibility and stability, potentially altering catalytic activity and drug binding properties. These findings highlight the importance of considering genetic variants in personalized medicine and drug development. By investigating CYP2B6’s function and structural changes induced by missense variants, this research advances our understanding of the enzyme’s role in drug metabolism. The study utilized computational tools such as GROMACS and AMBER for pre- and post-simulation analysis, with clustering and DSSP used to assess protein structures. Variants I328T, K282R, P428T and R140Q exhibited significant deviations in enzyme dynamics, while other variants caused minor shifts. Overall, the findings provide insight into the relationship between genetic variants and enzyme function, contributing to bioinformatics and molecular modelling approaches in drug discovery. Future studies could explore the structural and fuctional impacts of CYP2B6 bound to substrates such as antimalarials, expanding the investigation to a broader range of missense variants. , Thesis (MSc) -- Faculty of Science, Biochemistry, Microbiology and Bioinformatics, 2025

- Description: How does a classical world emerge from a quantum world? Can this emergence occur without invoking non-unitary processes such as measurements? Recently, an approach that makes use of just a Hilbert space and the associated Hamiltonian to explain the emergence of a classical world has been proposed. To understand this approach, we will require a clear understanding of the nature of measurements in quantum theory and the different interpretations of it. We then progress onto discussions regarding quantum Darwinism and related _elds of knowledge and how they \bypass" the problem of measurement in quantum theory. Then, we discuss how, using the appropriate choice of factorization of a Hilbert space into a system and an environment and using an acceptable basis observable, we can obtain a quasi-classical state of a system. This approach has previously been applied to study one limit (when interactions dominate the Hamiltonian), but we generalize by applying it to the opposite limit (when interactions are minimal) and suggest a method for the general case (when interactions are neither minimal nor dominant). We then look at Hilbert space fundamentalism, which is the idea that a vector in Hilbert space is the fundamental nature of reality. Hilbert space fundamentalism is a generalized application that takes the idea of the emergence of a classical world from a quantum one and applies it to the Universe as a whole. This leads to the question: could Hilbert space fundamentalism be a candidate for the fundamental theory? Before we evaluate Hilbert space fundamentalism as a candidate fundamental theory, we analyze the theory and inquire as to what makes something a fundamental theory. To understand Hilbert space fundamentalism, we see what a model of the world it predicts looks like. This is done by proposing a mapping from a fundamental Hilbert space to emergent space times utilizing entanglement and the aforementioned recently proposed approach that makes use of Hilbert spaces and Hamiltonians to explain the emergence of classical worlds. To determine if Hilbert space fundamentalism could be a fundamental theory, a set of criteria (completeness in all domains, self-contained, and that speci_c theories emerge from it) is noted. We find that Hilbert space fundamentalism, when viewed through these criteria, cannot be the fundamental theory. , Thesis (MSc) -- Faculty of Science, Physics and Electronics, 2025

- Description: Women business leaders are generating a tremendous impact in their markets, industries and communities through innovation, job creation and economic growth. However, their contributions are often lost in the prevailing narrative that women are over-represented among the poorest and most vulnerable entrepreneurs globally. A review of the extant literature has postulated challenges that women entrepreneurs faced several challenges in the ecosystem in which it operates. Women entrepreneurs have access to limited capital as compared to its men counterparts, fewer opportunities to network and build relationships with other entrepreneurs, investors, and mentors, which affects their access to resources and knowledge. Due to the issue of gender-based stereotypes and biases that women entrepreneurs constantly face, they are unable to meet mentors who can provide them with guidance and support to grow their business. These women-specific challenges have become barriers limiting the growth of women entrepreneurs, however insufficient reports highlight how these hindering factors can create opportunities for the growth of women entrepreneurs. Dwelling on the Process theory, the study explored the impact of Ghana’s entrepreneurial ecosystem on women’s entrepreneurial performance with the moderating role of entrepreneurial identity. The study was a cross-sectional quantitative research design with data collected from 413 women entrepreneurs in the Greater Accra Region using structured questionnaire collected using the survey monkey online tool. The data was analyzed using IBM SPSS v.25 and the PLS-SEM v.4.0. The first objective was examined through 12 hypotheses, while the second was analyzed using 2.The study finds that access to finance has positive and insignificant effect on the entrepreneurial performance of women in Ghana. Likewise, education and training have a negative and insignificant effect on the market and operational performance of women entrepreneurs in Ghana. The results of the study postulated that the availability of infrastructure and resources has a negative but significant effect on both the market and operational performance of Ghanaian women entrepreneurs. The results of the study further reported a positive but insignificant impact of network and social capital on the market performance and operational performance of women entrepreneurs in Ghana. The results of the study in relations to the regulatory environment and women entrepreneurial performance indicates an insignificant relationship between regulatory environment and market performance and regulatory performance whilst cultural and social factors within the Ghanaian ecosystem negatively but significantly influence the entrepreneurial performance of women in Ghana but innovation and knowledge spillover have a positive and significant impact on both the market performance and operational performance. Furthermore, the findings of the study suggest that Ghana's entrepreneurial ecosystem may not have a substantial direct impact on women's entrepreneurial performance in Ghana. Further practical and theoretical implications of the study are discussed in the thesis. , Thesis (PhD) -- Faculty of Commerce, Rhodes Business School, 2025

Le thisisi iza kushukuxa indlela abathe aba babhali bahlaba ngayo ikhwelo ekubonakaliseni Ubuntu nendlela obunokuthi Ubuntu busetyenziswe ngayo ukuqinisekisa ukuba umzi oNtsundu awubonwa njengalowo ungaphucukanga, ungenakho ukusebenzisa iingcamango zobuntu ukuwuphuhlisa. Uphando luza kugocagoca ezi ncwadi zilandelayo: Umyezo ngokubhalwe nguJ.J.R. Jolobe ; Ilitha (isihobe) ngokubhalwe nguJ.J.R. Jolobe ; Elundini loThukela (iprozi) ngokubhalwe nguJ.J.R. Jolobe ; Isizwe esinembali: Xhosa histories and poetry (1837-1888) ngokubhalwe nguW.W. Gqoba ; Umoya wembongi: Collected Poems (1922-1935) ngokubhalwe nguJ. Solilo Uphando lukhethe ezi ncwadi zikhankanywe apha ngentla kuba zona ziyibalisa ngokucacileyo imbali yamaAfrika. Ezi ncwadi zinembali etyebileyo nezithi zisebenze njengokubhebhetha indlela amakoloniyali athi ayibhala ngayo imbali yamaAfrika eyayijolise ukuwajongela phantsi. Kwakhona olu ncwadi lwabhalwa ngexesha apho kwakukho imingeni ekunikeni inkcazo evakalayo ngokuba kuthetha ukuthini ukuphucuka, nokuba amaAfrika ayezibandakanya njani ukulwa nokuphikisa ingcaciso yendlela yokuphila kwamaAfrika yempi yaseNtshona. Ezi mbalo kungaxoxwa ngelithi, zithi zibe zezo zinike ngcaciso yimbi ngomba wempucuko leyo ingenokoyanyaniswa neengcamangco zaseNtshona. Apha kwezi ncwadi kuza kuhlutywa indlela Ubuntu obuthe baphuhla baze baphinda badodobala ngayo phantsi kolawulo lwempi yaseNtshona. Ekwenzeni oko, umphandi akayibethisanga ngoyaba imbali yoMzantsi Afrika neAfrika nje ngokubanzi, imbali yobukoloniyali. Yile mbali yobukoloniyali ethe yabangela ukuba aba babhali bezi ncwadi eziza kuphicothwa luphando bayithathele kubo ezandleni indima yokuqinisekisa ukuba iingcamango nemimiselo yobuntu yileyo bathi babhale ngayo ngeenjongo zokwenza uluntu lungaphulukani nokuxabisa Ubuntu njengefilosofi. Uphando lubone kubalulekile ukuba lulandele iingcamango zeAfrocentricity nezo zomanyan lwamaAfrika (Pan Africanism) ekubhentsiseni obu buntu bubonakaliswa ngaba babhali. Uphando luchonge ezi thiyori zimbini, eyeAfrocentricity kwakunye neyomanyano lwamaAfrika (Pan Africanism) kuba zombini ezi thiyori zikhokelisa phambili ukuxatyiswa kwamaAfrika njengabantu ekukudala benazo iifilosofi ezijolise ekuphuhliseni umzi oNtsundu. Kubonakele kufanelekile ukuba iphulo lokuphanda ngendlela Ubuntu obubonakaliswe ngayo ngaba babhali lenziwe ukukhumbula imisebenzi emikhulu eyenziwe ngamaqhawe abantu abaNtsundu nabathe banegalelo elikhulu ekuphakanyisweni koncwadi lwemveli kwakunye nenkqubela phambili kwimfundo yabantu abangamaAfrika. Ngokuphandle uncwadi lwaba babhali lubonakele luyinxalenye yobomi babo. Kukwakufumaniseka ukuba babhale bandululwe zizinto ezithe azabaphatha kakuhle ebomini babo zaze ezo zinto zawuphazamisa umoya wabo nentlalo yabo bada baqonda ukuba mababhale, baphokoze oku kuphuphuma kweengcinga zabo ukuthuthuzela kwanokuphilisa abanye abantu abathe badibana neenzima ezinjalo zobomi. Phakathi kwezo meko singabala iimeko zopolitiko zeli lizwe ezithe zabuchaphazela ubomi babo, imeko yezemfundo ethe yabonakala inomkhethe, iinqobo zenkcubeko ekuthe kwaphawuleka ukuba zibethiswe ngoyaba ngabo basemagunyeni de zenza noluntu lungazithatheli ngqalelo. Ezi meko zazibonwa njengezo zingelolutho ekuphuhliseni ubomi boluntu nje ngokubanzi. Oku kunyhashwa kwamalungelo abantu kwakunye neemeko ezimbi abathubeleze kuzo zibe sisizekabani sokwenziwa kolu phando ngobuntu nokuvuselela izazela zoluntu. Ezi mbalo zihlalutyiweyo ziquka nogxekoncomo lwazo zenza kanye le nto ichazwe kuphando, ukudakanca indlela Ubuntu obungasetyenziswa ngayo ukuphuhlisa isizwe esiNtsundu. Ziimbalo ezi ezigqithisa umyalezo neembono zaba bahlali ngokulondolozwa kwenkcubeko igcinwe encwadini njengamabali anika umdla erhwebesha uthando loncwadi kwanobuzwe babafundi abaNtsundu ngokubanzi, ingakumbi abafundi abangamaXhosa kuba babhalele bona ikakhulu. Ngababhali aba ababhale ngesiXhosa esiphakamisa inkcubeko yabo. Okuphawulekayo ngokukodwa kuJolobe yinto yokuba kwinoveli yakhe ethi, Elundini loThukela (1959) ude wasebenzisa iilwimi ezimbini isiHlubi kunye nesiXhosa eziqulethe iinkcubeko zazo. Ukongeza, ekubhaleni ngolwimi lwabo lwenkobe, aba babhali balandela ikhondo nesikhokelo sabantu abafana noMqhayi, noWa Thiong’o abazimvo ngokulondolozwa kolwimi noncwadi zikwasetyenzisiwe ukubonakalisa ukubaluleka kweelwimi zamaAfrika kuncwadi. Ekuhlalutyeni ezi mbalo zikhethiweyo, umphandi ukhethe ukulandela indlela yophando eyikwalitheyithuvu ngokugxininisa kuhlalutyo lomxholo. Isizathu sokuba indlela enjalo ibe iyasetyenziswa kukuba idatha ehlalutyiweyo ivela kwidatha esele yapapashwa, iincwadi ukutsho. Le ndlela yindlela eya kuba sisikhokelo esiphambili somphandi ukuqinisekisa ukuba iinjongo zophando ziyafezekiswa. Uphando lufumanise ukuba aba babhali bakhethiweyo bathe ngokwenene banendima abayenzayo ukuqinisekisa ukuba iziseko zobuntu ziyalondolozwa. Oku kuqala kwimiba engenkcubeko apho kuxoxwe ngelithi, umntu oNtsundu kuyafuneka ukuba angayibethisi ngoyaba into yokuzingca ngobuni bakhe. Kananjalo njengababhali ababe bhala beqwalasela yonke imiba yentlalo, into engokuzilanda ngokobuzwe yinto ebonakala isembindini kwiimbalo zabo njengoko besenza ikhwelo ebantwini abaNtsundu ukuba baze bangayilibali imvelaphi yabo. Kumba wezemfundo ingakumbi uGqoba ubalula ukubaluleka kwemfundo yemveli. Kolu phando kufumaniseke ukuba kwiimbalo zabo ababhali bayilwela ngamandla into yokumanyaniswa kwemfundo yaseNtshona naleyo yemveli yamaAfrika. Oku ingasisakhelo sokuqinisekisa ukuba umntwana womgquba uyafikelela kwimfundo ekwaziyo ukuthetha ngeengxaki ezihlangabezana nabantu abaNtsundu gabalala. , Ubuntu as an African philosophy with its focus on issues of good behavior and welfare of black Africans has forever been an unending debate on various spheres of life: those of politics, education, and governance, to name a few. Even though it is a debate with new avenues daily, there is limited research on the works of W.W. Gqoba, J. Solilo, and J.J.R. Jolobe on how they have argued on ways in which the values of Ubuntu may be preserved. This study is therefore undertaken to investigate exactly how these writers maintained in their writings ways in which Ubuntu can be used to ensure black Africans are not seen as a society that is ‘backward’, a society that cannot use Ubuntu principles for development. The research will examine the following books: Umyezo (poems) by J.J.R. Jolobe ; Ilitha (poems) by J.J.R. Jolobe ; Elundini loThukela (prose) by J.J.R. Jolobe ; Isizwe esinembali: Xhosa histories and poetry (1837-1888) by W.W. Gqoba ; Umoya wembongi: Collected Poems (1922-1935) by J. Solilo. In short, it is argued in the study that the selected texts are fine literary products and that their narratives were created following African history. They form part of negating the negative element that has been created by the accounts of colonial masters, as such an account of history was meant to undermine Africans: rich literature and history. Moreover, they were written at a time when there were challenges associated with civilization: what was meant by it and how Africans related to the idea as per Western standards. These texts, it could be argued, present an alternative on this matter by removing Western thoughts on what really are the elements of cultural civilization. In an in-depth analysis of selected writers’ texts, it was important to examine the ways in which Ubuntu has developed and evolved over the years under the administration of Western powers. In the analysis, the researcher did not turn a blind eye to the colonial history of South Africa and that of Africa in general. In that history, an argument is as follows: the thoughts and values of Ubuntu as captured by these writers are to remind people to appreciate Ubuntu as a philisophy. In my analysis, it was important to use theories such as Afrocentricity and Pan-Africanism in understanding and decoding Ubuntu as depicted in the writings of the selected writers. In choosing these theories, it is due to their main argument emphasizing the value of being African and the fact that Africans have long had their philosophies meant for the betterment of the society. It seemed appropriate to investigate how Ubuntu, as shown by these writers, is recorded to act as a reminder of the great works done by Africans who contributed greatly to the promotion of African literature as well as progress in the education of African people. The literature of these writers should be seen as an integral part of their lives. It is also found that they wrote because of the ills that affected their lives and disturbed their spirit and well-being until they realized that they should write and express their thoughts to comfort and heal other people who have encountered such hardships in life. Among those are the political conditions of this country that have affected their lives, the educational situation that has been shown to be biased, and cultural things that have been noticed to be ignored by those in power as they made the public not pay attention to them. This is because they were seen as having little value in the development of human life in general. That is why this research on Ubuntu could be seen as an initiative aimed precisely at those ideas that can be 'revitalized’ by conscientious people. The analysis of literary texts includes criticism to address the main question in this research: how Ubuntu can be used to develop the Africans. This is the kind of literature that conveys the message and ideas on the preservation of culture as preserved in the books with interesting stories that appeal to the love of literature and the nationalism of Africans in general, especially Xhosa people because they wrote mainly for them. It is these writers who wrote in Xhosa that promote their culture. What is particularly remarkable about Jolobe is the fact that in his novel, Elundini loThukela (1959), he used two languages, isiHlubi and isiXhosa, which contain their own cultures. In addition, in writing in their mother tongue, these writers follow the path and guidance of people like Mqhayi and Wa Thiong'o, whose views on the preservation of language and literature have also been used to show the importance of African languages in literary analysis. In the analysis of these selected texts, I have opted to follow a qualitative research approach with a focus on content analysis. The reason behing such an approach is the fact that the data so analysed is from existing data, books. This approach is one that will be a key guide for the researcher to ensure that the aims of the study are achieved. In this research, it was found that these selected writers really have played to ensure that the fundamental values of Ubuntu are preserved. This starts with non-cultural issues: it has been argued that the Africans should not ignore the pride of their identity. Also, as writers who wrote considering all social issues, the issue of national identity is something that appears at the centre of their writings as they call upon Africans not to forget their origins. In terms of education, Gqoba especially mentions the importance of African traditional education. In this research, it has been found that in their writings, the writers are strongly advocating for the integration of Western education with that of African traditional education. This could be taken as framework to make sure that the African child has access to an education that addresses the problems faced by Africans at large. , Thesis (PhD) -- Faculty of Humanities, Languages and Literatures, 2025

- Description: Rhodes University Honorary Doctorate Citation (5 April 2024) Tandabantu Tennyson August: 1980s. South Africa. In the Bantustans of the time, like the Transkei, the youth have little reason for hope. They have much reason for despair. Their choices seem limited to the politics of struggle or to crime, an attempt to gain some kind of advantage from the meagre and unacceptable options on offer. In those bleak times, what was needed was visionaries. People who could see beyond the current circumstances to a different future and imagine how best to prepare for it. Not as idealists, but as pragmatists. What would happen once circumstances change, once the struggle had succeeded? Would we be ready for it? What qualities would the youth need to have in order to both benefit from and participate in a new dispensation? One such visionary was Tandabantu Tennyson August, and it is my distinct pleasure to have the opportunity to tell you more about him. Born in 1948, Mr. August matriculated from Healdtown High School, before pursuing higher education at the University of Transkei, where obtained a Bachelor of Arts degree majoring in English and Geography. This was followed by Comparative Curriculum Studies at the University of South Africa, alongside obtaining teaching certificates from Lovedale and Cicira teacher training colleges, with majors in Physical Science, Mathematics, Science, and Mathematics. This solid educational foundation laid the groundwork for his impactful career in education. He taught at Wongalethu High, St Johns College and was deputy principal at Norwood, before taking up his first principalship, at Thanga High School in 1980. From 1984 to 1990 he was principal of Ndamase High School. During his tenure there, the matric pass rate never fell below 90%. From 1991 to 1995 he was principal Isivivane High School during which time the school was promoted from a primary to a high school. Following his distinguished service at schools, he worked at the Eastern Cape Department of Basic Education, first as a deputy chief education specialist (1996 – 2006) and then as chief education specialist (2006-2010). During that time, he played a pivotal role in establishing (in conjunction with Rhodes University) and being the provincial coordinator the Advanced Certificate in Education in English, followed by ACEs in mathematical literacy and life orientation. In 2016 he received a provincial teaching award for excellence. In 2017 he was awarded the Kade Asmal award for excellence in teaching. To this day, he remains an Executive member of the eastern cape Education advisory council. Quite a career. But there’s something I haven’t mentioned. He was also an accomplished rugby player of international standing. While at Lovedale College, he was selected to represent Border and then the South African African Rugby Board, playing England in Gqeberha in 1972, in a team that would later be known as the black springboks. He eventually received his green and gold springbok blazer as just recognition of his achievement. He incorporated his love of sport into his vision for the youth under his care, as part of his overriding mission of educating the whole person. He got everyone involved in sport, if not as a player, then as a supporter.

- Description: Rhodes University Honorary Doctorate Citation (5 April 2024) Tandabantu Tennyson August: 1980s. South Africa. In the Bantustans of the time, like the Transkei, the youth have little reason for hope. They have much reason for despair. Their choices seem limited to the politics of struggle or to crime, an attempt to gain some kind of advantage from the meagre and unacceptable options on offer. In those bleak times, what was needed was visionaries. People who could see beyond the current circumstances to a different future and imagine how best to prepare for it. Not as idealists, but as pragmatists. What would happen once circumstances change, once the struggle had succeeded? Would we be ready for it? What qualities would the youth need to have in order to both benefit from and participate in a new dispensation? One such visionary was Tandabantu Tennyson August, and it is my distinct pleasure to have the opportunity to tell you more about him. Born in 1948, Mr. August matriculated from Healdtown High School, before pursuing higher education at the University of Transkei, where obtained a Bachelor of Arts degree majoring in English and Geography. This was followed by Comparative Curriculum Studies at the University of South Africa, alongside obtaining teaching certificates from Lovedale and Cicira teacher training colleges, with majors in Physical Science, Mathematics, Science, and Mathematics. This solid educational foundation laid the groundwork for his impactful career in education. He taught at Wongalethu High, St Johns College and was deputy principal at Norwood, before taking up his first principalship, at Thanga High School in 1980. From 1984 to 1990 he was principal of Ndamase High School. During his tenure there, the matric pass rate never fell below 90%. From 1991 to 1995 he was principal Isivivane High School during which time the school was promoted from a primary to a high school. Following his distinguished service at schools, he worked at the Eastern Cape Department of Basic Education, first as a deputy chief education specialist (1996 – 2006) and then as chief education specialist (2006-2010). During that time, he played a pivotal role in establishing (in conjunction with Rhodes University) and being the provincial coordinator the Advanced Certificate in Education in English, followed by ACEs in mathematical literacy and life orientation. In 2016 he received a provincial teaching award for excellence. In 2017 he was awarded the Kade Asmal award for excellence in teaching. To this day, he remains an Executive member of the eastern cape Education advisory council. Quite a career. But there’s something I haven’t mentioned. He was also an accomplished rugby player of international standing. While at Lovedale College, he was selected to represent Border and then the South African African Rugby Board, playing England in Gqeberha in 1972, in a team that would later be known as the black springboks. He eventually received his green and gold springbok blazer as just recognition of his achievement. He incorporated his love of sport into his vision for the youth under his care, as part of his overriding mission of educating the whole person. He got everyone involved in sport, if not as a player, then as a supporter. Especially during his time as principal of Ndamase High School, I am led to believe, it was extremely intimidating for opposing teams to play them. Not only at Ndamase home games, but especially at their away games. There would be one bus for the team players, and six buses for the supporters. From 1986 – 1990: he was president of the Transkei schools` sports union (TSSU). But there’s yet another thing I haven’t mentioned.

- Description: Although South Africa has achieved considerable steps in development over the last thirty years, post-apartheid South Africa is characterised by widespread poverty, high unemployment and systemic inequality. According to the country’s National Planning Commission, education is central to achieving the overarching democratic goals of eliminating poverty and reducing inequality. This positions education as an important site for the liberation and well-being of our country’s majority. This case study takes a community psychology perspective on education; more specifically the education-development nexus wherein Non-Governmental Organisations (NGOs) are centrally positioned. NGOs are contentiously positioned in the development discourse. Nonetheless, they have played a key role with regards to siding with the poor, the excluded, persistently marginalised and oppressed majority and to bringing about social justice, following South Africa’s colonial and apartheid histories, as well as in the current democratic dispensation. This study situates a local NGO, GADRA Education, within the country’s socio-political and educational landscape. Founded in the 1950s and located in Makhanda, it has been operating in the rural Eastern Cape province for more than sixty years. In the present-day, GADRA Education positions itself at the centre of a dense network of education institutions in Makhanda, including Rhodes University, and collaborates with a number of education stakeholders in the small city. The case study consisted of two consecutive phases: a Foucauldian discourse analysis of GADRA’s annual reports between 2012 and 2021, followed by individual narrative interviews with 13 organisational members. An Africa(n)-centred community psychology orientation, revealed counter-discourse to the national “crisis in education” discourse surrounding the NGO. The discourse of crisis produced the legitimation for GADRA Education’s continued existence, action and embeddedness in Makhanda. The discourse of transformation informed their modes of support across primary, secondary and higher education. The discourse of access and participation constructed the NGO as a bridge and link between phases of education. The discourse of collaborative partnerships enabled solidarity between state and non-state actors towards educational change. Finally, the discourse of development positioned development at a grassroots level. These constellations formed GADRA Education’s counter-discourse, which produced the Organisation’s apparatus of resistance, formulated as situated praxis. The 5 organisational members’ narratives revealed the apparatus’s impacts on the subjectivities of youth in Makhanda in engendering hope and driving educational change in the city. In contrast to conceptions of education NGOs who work in the public schooling sector making little progress in dismantling educational inequity, this study illustrates the techniques of resistance leveraged, in the context of collaborative partnerships, by the local NGO. These techniques have wider applicability for education-development practitioners concerned with transformative change in their educational locales. It illustrates the principles and modes by which NGOs can operate in solidarity with the persistently marginalised majority, and thus contribute to shaping our imagined educational futures. I argue that psychology is a useful site to think about justice. Critical psychological theory can enable a deeper understanding of practice that contributes to impactful community organisation, intervention and resistance in the country’s education sector. The operationalisation of the values and principles of community psychology can make important contributions at the nexus of theory and practice in working towards educational, and ultimately social, change. , Thesis (PhD) -- Faculty of Humanities, Psychology, 2024

- Description: Silent Mask Theatre in South Africa has the potential to cut across linguistic divides and deliver a product that offers an intimate, unique experience for the audience as well as the actor. South Africa not only has a complicated history, but also 11 languages (12 if one counts South African Sign Language – SASL -, which still holds a curious position of being counted official or not), and the one that theatre-makers choose to present in gives a certain “authority” to the production. Silent masks remove the need for linguistic understanding, something necessary for more abstract thought, and focusses instead on the emotional relevance and interplay between characters. In doing so, it proves an important way to create relevance for an audience, creating a delicate dance between the Mask (character and thereby text), how the actor plays it, and then the closing of meaning through the audience experience. Thus, is created a trialogue between these elements that gives the production the opportunity to speak to the hearts and minds of the audience. Globally, the study of silent character masks is still relatively new, with proponents of it only coming to the fore in the past few years (Wilsher, 2007). Mask Theatre has grown exponentially in the UK and Europe with companies like Vamos Theatre, exploring PTSD in works like A Brave Face (2018) or death in Dead Good (2021), and Familie Flöz either on the more whimsical side like Hotel Paradiso (2011) or the more hard-hitting Infinito (2006), gaining popularity and exposure. In South Africa, there is strangely not an indigenous tradition of masks, as opposed to other parts of Africa. This is fascinating, and probably points towards a more “oral tradition” of South Africa/Africa. However, the author aims to point out the ways that the silent mask entered South African consciousness at a time where more attention was being paid to “performing objects” (Proschan, 1985), and particularly in Cape Town with the advent of the Out the Box Festival. This thesis aims to contextualise Visual Theatre and Mask Theatre in a South African context, seeing within it a movement towards a more global perspective of puppetry, material performances, and performing objects. Although “ghettoised” for a long time (Taylor, 2004), performing objects emerged and became a leading case for the primal “text” of a performance. Handspring Puppet Company, Janni Younge, and the author’s company, FTH:K, became primary grounds of contestation against more conventional, text-based theatre. Starting with a reflective account of the author’s journey towards masks, the thesis branches out into a reflection on its author’s pedagogical praxis, and how silent masks work, before critically reflecting on and analysing his key works, such as Pictures of You (2008-2013), which deals with home invasions and grief, and Benchmarks (2011), which deals with the wave of xenophobia that hit South Africa around that time. . This were built from the ground up, working with current issues both in the author’s, and the country’s, mileau. In the last two decades, performing object work in South Africa has begun to flourish. This is the first thesis to investigate mask work in the country during this period. Its possibilities for Screen and Stage Acting are still being explored. , Thesis (PhD) -- Faculty of Humanities, Drama, 2024

- Description: This study conducted a detailed analysis of 277 headlines using content analysis, focusing on how News24 portrays racial protests, particularly within the Black Lives Matter (BLM) movement. It explored News24's coverage of BLM protests from March to December 2020, uncovering various framing strategies and language nuances in news headlines. The research aimed to identify thematic frames, linguistic patterns, and overall media framing of BLM protests. The findings highlighted different framing strategies, including legitimising, conflict, and delegitimizing frames, along with the impact of descriptive language on audience perceptions. The study concluded that media framing is dynamic, responding to evolving events and public discourse, and provided recommendations for media transparency, diversity in newsrooms, media literacy, and ethical reporting. Future research suggestions include comparative analyses, audience reception studies, and policy impact assessments to deepen understanding and inform strategic interventions in media representations and public discourse on racial justice. Overall, the study contributes valuable insights into media framing practices and their impact on societal perceptions of racial justice issues. , Thesis (MA) -- Faculty of Humanities, Psychology, 2024

- Description: Water is an important natural resource with multiple domestic and industrial uses. South Africa has a water scarcity problem, with domestic and industrial demand projected to increase due to population growth. One affected area is the Koue Bokkeveld (KBV), an agricultural catchment in the Western Cape. Water scarcity, especially in the summer, can cause conflicts among the farmers. This study sought to determine the extent to which Agent-Based (AB) modelling could be used to model the KBV catchment area and simulate future climate and usage scenarios. The study used the ComMod methodology as it allows stakeholders to be involved at each step of the modelling process, thus improving the model’s credibility as a decision-support tool (DST). The model was implemented using Cormas, an Agent-Based Model (ABM) implementation framework built with the Smalltalk language. The model was verified and validated through consultations with the catchment coordinator and through workshops with stakeholders. The ABM reflected the catchment characteristics. Farms known to have water shortages had water shortages in the ABM. However, there was one that did not have shortages, which is attributed to land use change. The ABM was used to run multiple simulation scenarios, and it provides simulation results at the crop field, farm and catchment levels, which allows the ABM to be used as a bottom-up DST. , Thesis (MSc) -- Faculty of Science, Computer Science, 2024

- Description: Introduction: Kinematic studies identify elbow extension and wrist flexion as key movements for bat swinging speed during cricket batting. Knowledge of lead arm muscle activation during cricket batting may provide a greater understanding of the mechanics leading to the generation of faster bat speed. Aim: The current investigation aimed to determine selected muscle activation of cricketer's lead arm, maximum bat swinging speed and angular separation of the pelvis and thorax in the transverse plane (known as the X-angle) during a distance-hitting batting protocol. Materials and Methods: 12 cricket players playing for a South African school 1st XI school team aged 16-19 years completed a distance-hitting batting protocol. Due to issues in data recording two participants' data was excluded leading to 10 participants being kept in the final analyses.Participants attempted to hit straight lofted drives while facing full-length deliveries at 80-100 km.h-1 from a bowling machine. Each participant faced 12-24 balls split into overs while lead arm muscle activation, bat speed, and angle of lead-elbow flexion were recorded. Each participant's elbow and wrist flexors and extensors were monitored by electromyography (EMG) units while they batted. The EMG units were placed on the wrist flexor and extensor origins and on Triceps and Biceps Brachii. Muscle activation for each muscle was recorded in millivolts (mv) and divided by the maximum measurement of voluntary muscle activation to determine the percentage of maximum voluntary contraction (%MVC) during each shot. Percentage MVC for batting phases of backlift, downswing, contact and follow-through were averaged to compare average %MVC per muscle across all batters and obtain inter-participant variability. Lead arm elbow angle and the %MVC of the elbow and wrist muscles will be compared between successful and unsuccessful shots for analysis. Each participant's lead arm elbow angle was monitored in degrees of flexion by a goniometer placed across the anterior aspect of the elbow joint. Due to the data not having a normal distribution, non-parametric tests were used to establish the variance between dependent variables. To determine the effect of multiple groups on the independent variables a Kruskal-Wallis test for ANOVA was used. Where significant differences were identified, multiple pairwise comparisons were completed to determine where the differences occurred. Results: Successful Lofted straight drives (32 shots) were compared to unsuccessful shots (101 shots) across all participants. Participants and batting phase were found to be significantly different for lead arm elbow angle and muscle activation however shot type was not found to be significantly different. Meaning that lead arm elbow angle and muscle activation differ based on the participant observed or based on the batting phase observed. The backswing phase recorded a higher amount of elbow flexion (155.25°) for Lofted straight drive compared to unsuccessful shots (157.86°) and lower activation across all muscles for Lofted straight drive. The lofted straight drive had a higher amount of elbow flexion (129.52°) compared to unsuccessful shots (149.24°) for the downswing phase and muscle activation was similar with greater variation for unsuccessful shots. At contact Lofted straight drive had a higher amount of elbow flexion (153.44° v 160.13°), and higher activation in the Biceps brachii (34.61% v 28.41%) and Triceps brachii (51.07% v 43.02%). For the follow-through phase Lofted straight drives had a higher amount of elbow flexion (144.87° v 149.59°) and greater Forearm extensor activation (37.13% v 31.28%). There was a large variation across all phases (coefitient of variation between 8.79%-70.28%) with backswing having the least variation and contact having the greatest. Meaning that the backswing phase is fairly predictable for batters and the contact phase is highly variable. Conclusion: Muscle activation increased in the last few milliseconds before contact. The Forearm extensor had the greatest activation during the backswing and follow-through phases. During the downswing phase, Forearm flexors had the greatest activation and at contact, the Triceps brachii had the greatest activation. This study emphasizes the importance of forearm and elbow muscle for batting. Appropriate strengthening of the muscles could also help a batter execute a powerful lofted drive. Future studies with objective measures linked to batting success in prior studies can build on the importance of these findings for batter success. This study provides insight into individual batter techniques and identifies important topics for future research. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2024

- Description: Introduction: Kinematic studies identify elbow extension and wrist flexion as key movements for bat swinging speed during cricket batting. Knowledge of lead arm muscle activation during cricket batting may provide a greater understanding of the mechanics leading to the generation of faster bat speed. Aim: The current investigation aimed to determine selected muscle activation of cricketer's lead arm, maximum bat swinging speed and angular separation of the pelvis and thorax in the transverse plane (known as the X-angle) during a distance-hitting batting protocol. Materials and Methods: 12 cricket players playing for a South African school 1st XI school team aged 16-19 years completed a distance-hitting batting protocol. Due to issues in data recording two participants' data was excluded leading to 10 participants being kept in the final analyses.Participants attempted to hit straight lofted drives while facing full-length deliveries at 80-100 km.h-1 from a bowling machine. Each participant faced 12-24 balls split into overs while lead arm muscle activation, bat speed, and angle of lead-elbow flexion were recorded. Each participant's elbow and wrist flexors and extensors were monitored by electromyography (EMG) units while they batted. The EMG units were placed on the wrist flexor and extensor origins and on Triceps and Biceps Brachii. Muscle activation for each muscle was recorded in millivolts (mv) and divided by the maximum measurement of voluntary muscle activation to determine the percentage of maximum voluntary contraction (%MVC) during each shot. Percentage MVC for batting phases of backlift, downswing, contact and follow-through were averaged to compare average %MVC per muscle across all batters and obtain inter-participant variability. Lead arm elbow angle and the %MVC of the elbow and wrist muscles will be compared between successful and unsuccessful shots for analysis. Each participant's lead arm elbow angle was monitored in degrees of flexion by a goniometer placed across the anterior aspect of the elbow joint. Due to the data not having a normal distribution, non-parametric tests were used to establish the variance between dependent variables. To determine the effect of multiple groups on the independent variables a Kruskal-Wallis test for ANOVA was used. Where significant differences were identified, multiple pairwise comparisons were completed to determine where the differences occurred. Results: Successful Lofted straight drives (32 shots) were compared to unsuccessful shots (101 shots) across all participants. Participants and batting phase were found to be significantly different for lead arm elbow angle and muscle activation however shot type was not found to be significantly different. Meaning that lead arm elbow angle and muscle activation differ based on the participant observed or based on the batting phase observed. The backswing phase recorded a higher amount of elbow flexion (155.25°) for Lofted straight drive compared to unsuccessful shots (157.86°) and lower activation across all muscles for Lofted straight drive. The lofted straight drive had a higher amount of elbow flexion (129.52°) compared to unsuccessful shots (149.24°) for the downswing phase and muscle activation was similar with greater variation for unsuccessful shots. At contact Lofted straight drive had a higher amount of elbow flexion (153.44° v 160.13°), and higher activation in the Biceps brachii (34.61% v 28.41%) and Triceps brachii (51.07% v 43.02%). For the follow-through phase Lofted straight drives had a higher amount of elbow flexion (144.87° v 149.59°) and greater Forearm extensor activation (37.13% v 31.28%). There was a large variation across all phases (coefitient of variation between 8.79%-70.28%) with backswing having the least variation and contact having the greatest. Meaning that the backswing phase is fairly predictable for batters and the contact phase is highly variable. Conclusion: Muscle activation increased in the last few milliseconds before contact. The Forearm extensor had the greatest activation during the backswing and follow-through phases. During the downswing phase, Forearm flexors had the greatest activation and at contact, the Triceps brachii had the greatest activation.

- Description: Traditionally, Ismene’s refusal to help Antigone bury their brother in Sophocles’ Antigone tends to be regarded only in relation to Antigone’s own remarkable bravery. Antigone exists on the heroic level, Ismene on the ordinary; Antigone is courageous, Ismene is timid and submissive; Antigone is an idealist and an individualist, Ismene is convention and herd-bound. Ismene is, in many ways, presented as the antithesis of Antigone and Sophocles does indeed make use of her character as a foil to Antigone, but this thesis will argue that the relation between the two sisters is far more complicated than a dichotomous contrast between ‘extraordinary heroine’ and ‘average woman’. Like Antigone, Ismene is very much a character in her own right, and her emotions, motivations and impulses are every bit as realised and compelling as Antigone’s own. Both sisters have been deeply affected by the tragic misfortunes of their family, but their sad history affects each sister quite differently. Whereas Antigone’s instinctive reaction to Creon’s edict is a furious determination not to tolerate any further dishonour, Ismene’s equally instinctive reaction is to avoid the pattern of self-destructive inwardness that has plagued their family for generations. By offering a comprehensive re-examination of the key passages that have informed our critical reception of Ismene and the nature of her relationship with Antigone, this study aims to disrupt the established, and largely prejudiced, reading of Ismene as a model of feminine timidity and submission. Although Ismene is certainly no grand tragic heroine, titling the theoretical focus away from the death-oriented extremism of Antigone towards a more balanced consideration of the so-called ‘weaker sister’ not only allows for new insights into the nature of Sophoclean tragedy, but also challenges the very basis on which Ismene has so often been dismissed in favour of her more intrepid sister: the pervasive assumption that Sophocles has only given us one sister who is willing to risk her life for a principle. , Thesis (PhD) -- Faculty of Humanities, School of Languages and Literatures, 2024

- Description: Microplastics in rivers pose an ecological risk. Hydraulic biotopes form distinct flow patches that vary longitudinally along the river, potentially influencing the transport dynamics of microplastics. Macroinvertebrates exhibit adaptations to different hydraulic biotopes through their unique traits. These traits can mediate their exposure to microplastics, thereby imposing selective pressures on these organisms. Different taxa often demonstrate preferences for specific hydraulic biotopes characterized by distinct flow regimes. Understanding the transport dynamics of microplastics mediated by hydraulic biotopes and the potential exposure of macroinvertebrates at the hydraulic biotope scale is important for determining the fate of riverine microplastics and detecting species at risk. Both empirical and theoretical studies have highlighted the interconnectedness of hydrology, geomorphology, and microplastic transport in rivers, yet, there remains a gap in understanding how a hydro-geomorphological approach could enhance the understanding of the microplastic transport process. Little is known about the role of traits in driving macroinvertebrate exposure to microplastics at a scale relevant to ecological dynamics. This study addressed these gaps by applying a hydro-geomorphological approach to investigate the distribution of microplastics at the hydraulic biotope scale and assessed the potential exposure of macroinvertebrates using a trait-based approach. This study also explored the relationship between microplastic abundance and selected water physicochemical properties, as well as the influence of adjacent land use types. By integrating these aspects the research provided a comprehensive understanding of microplastics dynamics in river systems, shedding light on both environmental factors shaping their distribution and the potential impacts on aquatic organisms. The study was conducted over the wet and dry seasons (October 2021 – July 2022) at 10 sites located in the upper, middle, and lower reaches of the Swartkops and Buffalo River systems in the Eastern Cape Province of South Africa. The hydraulic biotopes (i.e., pools, runs, riffles) were grouped into two conceptualised forms, namely, sink and flush hydraulic zones and were characterized by hydraulic indices such as the Froude number and the Reynolds number. The flush hydraulic zone represents hydraulic biotopes where microplastics can potentially be remobilized quickly into suspension, and the sink represents biotopes where microplastics can potentially accumulate and remobilisation is far slower. Fast-to-moderate flowing hydraulic biotopes were conceptualised as microplastics flush zones while slow-flowing to still biotopes as microplastic sink zones. Samples were collected at different depths in each hydraulic zone to quantify suspended and settled forms of microplastics. Microplastics targeted in this study ranged in size from 0.063 mm to less than 5 mm. Classification was achieved through microscopic observation, and confirmation via Fourier Transform Infrared Spectroscopy (FTIR-ATR) was conducted for samples ranging from 0.5 mm to less than 5 mm. At the site level, settled microplastics showed statistically significant spatial and temporal variations between the sites, and between the seasons (P < 0.05). The suspended microplastic varied only spatially. Fibres and fragments were the dominant microplastic shape, while polyethylene and polypropylene were the dominant microplastic polymers. Suspended microplastics showed statistically significant variation between urban land cover and other land cover categories (industrial, agricultural, rural, and natural land cover). Microplastics abundance was associated with high levels of turbidity, total suspended solids, total inorganic nitrogen, higher temperatures and increasing electrical conductivity. At the hydraulic biotope scale, the mean occurrence of suspended microplastics (1.76 ± 1.44 items/L; mean + SD) in the flush hydraulic zone was higher than that in the sink zone (1.54 ± 1.46 items/L), while settled microplastics were more abundant in the sink hydraulic zone (1.82 ± 1.98 items/L) than the flush hydraulic zone (1.32 ± 1.49 items/L). This observation was in line with the prediction in this study. The mean suspended and settled microplastics concentrations were higher during the wet season across the flush and sink hydraulic zones than in the dry season. Global multivariate analysis of variance (MANOVA) and two-way analysis of variance (ANOVA) revealed significant spatial and temporal variations in settled microplastics abundances between the flush and sink hydraulic zones. The results indicated that geomorphologically defined units such as riffles and moderate to fast runs (flush) generally contained lower amounts of settled microplastics compared to pools and backwaters (sink). However, this distinction between the flush and sink microplastic zones was observed only for settled microplastics and not for suspended microplastics. Suspended and settled microplastics showed a statistically significant relationship with the Froude number index. The generalised additive model indicated that settled microplastics abundance distribution decreased significantly with increasing Froude number value in the flush zone. Suspended microplastics decreased at low Froude number values and showed an increasing trend at higher Froude number values of about 0.75. The results indicate the usefulness of the hydraulic biotope scale microplastic monitoring approach in detecting microplastic hotspots and explaining variations in microplastics abundances driven by instream hydraulics. Four traits and ecological preferences of macroinvertebrates including body size, gill type, feeding habit, and velocity preferences were selected and resolved into 17 trait attributes. The sink hydraulic zones such as pools were indicated to favour exposure to and ingestion of microplastics compared to the flush zones such as riffles and fast runs. Large body size macroinvertebrates were associated with the sink zone. Taxa with a very small body size had a higher likelihood for microplastics ingestion than taxa with other body sizes. Collectorgathering macroinvertebrates taxa that have operculate gills with small body sizes were more prone to exposure to microplastics in hydraulic biotopes with slow to very slow velocities. Fibres were the most abundant plastic ingested by macroinvertebrates preferring the flush zone while fibres and fragments were mostly ingested by those preferring the sink zones. The binomial logistic model revealed a highly significant result for the likelihood of operculate gill shape to clog in the sink hydraulic zone. The result of the binomial logistic regression indicates the usefulness of the trait-based approach for predicting exposure to microplastics. Overall, the study reveals the influences of hydro-geomorphological features on the transport dynamics of microplastics and the usefulness of the trait-based approach in the ecological study of microplastics in riverine systems. , Thesis (PhD) -- Faculty of Science, Institute for Water Research, 2024

- Description: Praying mantises (Dictyoptera: Mantodea) are an iconic group of predatory insects, comprising around 2500 species globally, that occur in all zoogeographic regions except the poles. Their presence in the social psyche of many cultures has existed for millennia, but until the past decade, Mantodea has received little attention from the scientific community as the constituent species are of little economic or medical importance. Africa is rich in praying mantis diversity, accounting for approximately 45% of all described species, yet it remains largely under-sampled compared to the New World and Asian regions. Recent exploration of Gabon and Central African Republic have proved fruitful, with new species descriptions being major highlights. A recent re-cataloguing of southern African praying mantises has proved useful as specimen identifications were checked, new distributions were recorded, and most importantly, it was revealed that museum collections have significantly more diversity than previously recorded. A meta-analysis of African praying mantises was conducted; we present a species checklist to the countries of Africa, including Madagascar and surrounding islands. Currently, 17 families, 182 genera, and 1104 species occur in Africa.Historically, the classification of praying mantises was based solely on morphological features, and the novelty of the field at the time made it unclear which characteristics were of taxonomic importance. The onset of molecular systematics brought attention to incongruences between morphological and molecular phylogenies, believed to be attributed to convergent evolution masking the underlying evolutionary processes that occurred. Significant progress has been made in the past two decades regarding Mantodean classification and most described genera have their phylogenetic position. With the addition of more African taxa, we present mantodean phylogenies for molecular and morphological data. Molecular phylogenies were estimated through Bayesian Inference and Maximum Likelihood analyses using two nuclear (28S and H3) and two mitochondrial markers (16S and COI) for 210 individuals that represented 24 of the 29 families globally. Morphological phylogenies were estimated through Maximum Likelihood analyses of a morphological data matrix comprising 149 characters for 248 individuals that represent 24 families. The same data matrix was used to produce a key to all African mantodean families, accompanied by their descriptions. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2024

- Description: Problematic Internet Use (PIU) and Substance Use Disorder (SUD) interact in complex ways that influence the current mental health landscape. Concurrently, the advent of the digital era has presented new difficulties, one of which is the emergence of problematic internet use as a significant issue that negatively impacts mental health. The increasing popularity of internet use has led to an increasing number of reports highlighting the potential negative consequences of overuse, such as substance use. Thus, the study aimed to synthesise literature on problematic internet use and substance use disorder, including the way in which they affect men, given that prior research has predominantly focused on women. The methods employed follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) which is largely based on a PRISMA statement and checklist, the JBI methodological guidance, and other approaches for undertaking scoping reviews. A total of 16 studies were eligible for final review, and the themes identified from the reviewed studies were obtained using Braun and Clarke’s thematic analysis. An analysis of the articles showed a large focus on gender differences in addiction patterns, vulnerability to problematic internet use across age groups, associations between substance use and behavioural addictions, problematic internet use and mental health disorders, the psychological consequences of problematic internet use and substance use disorders, and the various risk factors associated with the development of problematic internet use and substance use disorder. A clear understanding and conceptualisation of this behavioural addiction is vital, including the development and utilisation of appropriate and validated diagnostic and screening tools to measure its presence and, in turn, address it as an emerging mental health disorder. Focus should be given to the assessment of problematic internet use by distinguishing the two different forms, namely the generalised and specific forms of problematic internet use.

- Description: Problematic Internet Use (PIU) and Substance Use Disorder (SUD) interact in complex ways that influence the current mental health landscape. Concurrently, the advent of the digital era has presented new difficulties, one of which is the emergence of problematic internet use as a significant issue that negatively impacts mental health. The increasing popularity of internet use has led to an increasing number of reports highlighting the potential negative consequences of overuse, such as substance use. Thus, the study aimed to synthesise literature on problematic internet use and substance use disorder, including the way in which they affect men, given that prior research has predominantly focused on women. The methods employed follow the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) which is largely based on a PRISMA statement and checklist, the JBI methodological guidance, and other approaches for undertaking scoping reviews. A total of 16 studies were eligible for final review, and the themes identified from the reviewed studies were obtained using Braun and Clarke’s thematic analysis. An analysis of the articles showed a large focus on gender differences in addiction patterns, vulnerability to problematic internet use across age groups, associations between substance use and behavioural addictions, problematic internet use and mental health disorders, the psychological consequences of problematic internet use and substance use disorders, and the various risk factors associated with the development of problematic internet use and substance use disorder. A clear understanding and conceptualisation of this behavioural addiction is vital, including the development and utilisation of appropriate and validated diagnostic and screening tools to measure its presence and, in turn, address it as an emerging mental health disorder. Focus should be given to the assessment of problematic internet use by distinguishing the two different forms, namely the generalised and specific forms of problematic internet use. Additionally, given that there were very few to no qualitative studies conducted on the topic of problematic internet use, much less addressing the possible association with substance use disorder, an assessment of the individual’s experience, especially that of men, is lacking. Future research could therefore aim to incorporate more qualitative studies to address the above. Further research is also needed to clarify the nature of the relationship between problematic internet use and substance use disorder for the purpose of establishing possible causality, including the neurobiological substrates involved. , Thesis (MA) -- Faculty of Humanities, Psychology, 2024
