- Description: Human immunodeficiency virus (HIV) infection is associated with disturbed neurotransmission and aberrant cortical networks. Although advances in the imaging of brain microarchitecture following neuroHIV has added to our knowledge of structural and functional changes associated with HIV, no data exists on paediatric HIV using optical neuroimaging techniques. This study investigated the feasibility of optical neuroimaging in paediatric HIV using functional near-infrared spectrometry (fNIRS). We measured prefrontal brain activation while participants executed a sustained attention task. We specifically tested whether patients living with HIV and study controls could perform the study protocol and whether we could measure the typical fNIRS haemodynamic response associated with neuronal activity. Eighteen participants (10 HIV participants, mean age: 13.9, SD = 1.66 years; 8 controls, mean age: 14.8, SD = 1.28 years), matched for sex, grade, and socio-economic status, were included in the study. All participants completed the Stroop colour word test (SCWT). Oxygenated haemoglobin concentration and the deoxygenated haemoglobin signal were recorded from the dorsolateral prefrontal cortex and the frontopolar area (FA) using fNIRS. The control group performed significantly better in terms of reaction time on the congruent and incongruent condition (congruent: t (16) = −3.36, : incongruent: ). A pooled group analysis of the sample indicated significant activation in the DLPF and FA to the congruent condition of the SCWT (). Although cortical activation was noted in the DLPF and the FA in each of the groups when analysed independently, this neural activation did not reach statistical significance. The results show promise that fNIRS techniques are feasible for assessing prefrontal cortical activity in paediatric HIV. Future studies should seek to reduce the signal-to-noise ratio and consider inter-individual variability when measuring prefrontal activation in paediatric samples.

- Description: Computer Science education in sub-Saharan Africa has evolved over the past decades. The number of institutions offering distinct undergraduate programs has grown, thus increasing the number of students enrolling in the computer science discipline. Several computer science degree programs have emerged with one of the objectives being to satisfy the growing demand for local talent and skills. In this paper, we provide a snapshot of the evolution of undergraduate computer science education in selected countries in Sub-Saharan Africa over the past 20+ years and an overview of the developments in computer science education and observed trends. The setup of educational institutions in Africa and the operational context requires unique modalities for the design and delivery of computer science education that meets the demands of the industry, amongst others. This paper provides insights into the best practices in the computer science curricula in the selected countries, as well as an overview of the pedagogical and delivery approaches to computer science education. The paper highlights case studies from institutions in the selected countries, namely Uganda, South Africa, Ghana, Tanzania, and Kenya with a consolidated summary of the current and emerging challenges and opportunities in all these countries. The paper concludes by providing persectives on the future landscape of computer science in Sub-Saharan Africa.Computer Science Education in Selected Countries from Sub-Saharan AfricaBy Engineer Bainomugisha, Makerere University, Uganda, Karen Bradshaw, Rhodes University, South Africa, Martin Mabeifam Ujakpa, Ghana Communication Technology University, Ghana, Joyce Nakatumba-Nabende, Makerere University, Uganda, Lawrence Nderu, Jomo Kenyatta University of Agriculture and Technology, Kenya, Neema Mduma, Nelson Mandela African Institution of Science and Technology, Tanzania, Patrick Kihoza, Mzumbe University, Tanzania and Annette Irungu, Jomo Kenyatta University of Agriculture and Technology, Kenya

- Description: Trans-disciplinary research combines different fields into new conceptual and methodological frameworks. In this study, the SECI model of knowledge creation, which consists of Socialization, Externalization, Combination, and Internalization conversion modes, is used to analyze the implementation of a structured budgeting visualization system by a trans-disciplinary team. Through applied research in implementing a global budgeting system, budgeting assumptions are made explicit through visualization, transforming the approach to the budgeting process and its accuracy. This visualization, in turn, is enabled by assumptions underlying revenue planning, business services and employee compensation, and a visual process. The system displays a stepped approach, indicated by icons, representing the tasks involved in the budget process. For example, the system requires uploading the previous year’s information, setting the assumptions, calculating the suggested figures based on assumptions, and amending the proposed outcome. As adapted by Rice and Rice (2005), SECI is applied as the socialization of tacit-to-tacit budgeting assumption knowledge is solidified during the design phase of this transformation exercise. The externalization phase, in which budgeting assumptions are transformed from tacit to explicit, is evidenced during the configuration phase of the new system. The systemic collaboration results in the explicit assumptions being collectively leveraged across the regions during and after the “go-live” phase of system development. Finally, the internalization phase involves the explicit assumptions being transformed into new tacit knowledge as the experts evolve new assumptions derived from the transformation process. Semiotics provides variance information through hue, with, for example, darker colours indicating higher variances. This trans-disciplinary communication provides the means for increased efficiency and effectiveness. The resulting budget framework is visually validated through a heatmap by comparing the budgeting accuracy and assumption complexity between the different regions where it was implemented. In summary, value is added in developing a new data visualization process, focusing on the role of budgeting assumptions and using planning process visualizations. This approach improves communication efficiency, effectiveness, and understanding of budgeting while enhancing accuracy.

- Description: Following the COVID-19 pandemic we sought to determine the relationships between anxiety, hopelessness, alcohol use, perceived vulnerability to infection, resilience, traumatic stress, and satisfaction with life amongst university students at three tertiary higher education institutions in South Africa. Our participants were a convenience sample (N = 803) of South African students attending three universities. Participants completed an online survey that contained a battery of psychological measures that measured fear of COVID-19, Perceived Vulnerability to Disease, Resilience, Satisfaction with Life Scale, Hopelessness, Anxiety, PTSD, Alcohol Use, Traumatic Stress, and worry about infection with COVID-19. The mean age of participants was 25 (SD = 8.22), most of whom were female (51%). An increase in age amongst respondents was significantly positively correlated with hopelessness and life satisfaction, but also significantly negatively associated with symptoms of anxiety, PTSD, and alcohol use. Multivariate analysis showed that women reported significantly higher levels of fear of COVID-19, perceived vulnerability to disease, PTSD, and COVID-19 related worries compared to men and those identifying as “other.” Students at the urban university reported higher levels of fear of COVID-19, perceived vulnerability to disease, and COVID-19 related worries but lower levels of anxiety compared to those at the peri-urban and rural university. Students at the rural institution reported greater levels of alcohol use compared to those at the other institutions. Psychological distress among students was exacerbated during the pandemic. It may be useful to identify students in the first term who are struggling academically and to direct them to both academic and counseling support services.

- Description: We, Academic Development (AD) practitioners, question whether AD's objective in South Africa (SA) as a'liberatory educational and social movement'to enhance educational quality for all students, is effectively pursued. AD practitioners often work on the fringes of the academy, fighting for relevance and legitimacy within an increasingly performative and managerialist academic culture. Despite innovative AD initiatives AD work is criticised for being unresponsive, unreflexive, conformist, and lacking theoretical, scholarly, and critical engagement. We use critical pedagogical praxis, particularly the constructs of critique, reflexivity, power, and self-reflection, to interrogate the continuous tension between AD intention and practice. Through (un) conference methodology, this auto-ethnographic account of individual and collective engagements, using the" holding the mirror up" metaphor, critically questioned the tension and misalignments between the AD mandate and practices. Although in a SA higher education context, this research could be beneficial to HE contexts globally, given the ubiquity of AD work.

- Description: Interactions between people and the saltwater crocodile Crocodylus porosus frequently occur on islands and in coastal regions. Saltwater crocodiles impact people's lives and livelihoods by attacking them, resulting in minor or serious injuries, and by interfering in people's foraging activities. Retaliation may include killing the crocodiles involved. To reduce such human–crocodile interactions, data about the occurrence of incidents are required. We present data on encounters with crocodiles and attacks on people in the Roviana Lagoon, Solomon Islands. Data includes time of incident, gender, age and activity of the victim, water conditions and what happened to the crocodile after the incident. We used a questionnaire to capture the details of incidents that occurred during 2000–2020 in the villages of Dunde, Baraulu, Nusa Hope and Kozou. Most incidents were in the evening, mostly involving women, and most victims were aged 20–39 years or ≥ 60 years. In all cases people were attacked while gleaning for shellfish in the mangroves. Attacks occurred irrespective of whether the water was clear or murky, and in all cases the crocodiles were not killed. Such site-specific data will facilitate the formulation of strategies for reducing negative interactions between people and crocodiles in this particular location. Although the saltwater crocodile is categorized as Least Concern on the IUCN Red List, research such as this provides data that can be used for promoting coexistence with and conservation of this species.

- Description: In low- and middle-income countries (LMICs), the mental health consequences of trauma exposure pose a substantial personal, societal, and economic burden. Yet, the significant need for evidence-based mental health treatment remains largely unmet. To unlock the potential for mental health care for trauma survivors in lower-resource contexts, it is critical to map treatment barriers and identify strategies to improve access to evidence-based, culturally appropriate, and scalable interventions. This review, based on an International Society for Traumatic Stress (ISTSS) briefing paper, describes the treatment gap facing adults with traumatic stress in LMICs and identifies the barriers that contribute to this gap. We then highlight strategies for enhancing access to effective treatments for these populations, including task-sharing, the use of culturally adapted and multiproblem interventions, and digital tools to scale access to appropriate care. Finally, we offer recommendations for policymakers, researchers, and service providers to guide an agenda for action to close the treatment gap for trauma survivors in LMICs.

- Description: Ethnopharmacological relevance: In recent times the decriminalisation of cannabis globally has increased its use as an alternative medication. Where it has been used in modern medicinal practises since the 1800s, there is limited scientific investigation to understand the biological activities of this plant. Aim of the study: Dipeptidyl peptidase IV (DPP-IV) plays a key role in regulating glucose homeostasis, and inhibition of this enzyme has been used as a therapeutic approach to treat type 2 diabetes. However, some of the synthetic inhibitors for this enzyme available on the market may cause undesirable side effects. Therefore, it is important to identify new inhibitors of DPP-IV and to understand their interaction with this enzyme.

- Description: In 2017, Donald Trump signed the Protecting Life in Global Health Assistance (PLGHA), thereby reinstating the Global Gag Rule. The policy restricted all United States foreign funding from abortion-related activities. Little research reports the responses of recipients of this bilateral assistance. The study documents the South African government's responses to the PLGHA. We accessed Hansard parliamentary debates, interviewed four parliamentarians alongside one government official, and reviewed a USAID-funded initiative developed while the policy was in effect. We analysed the data using interpretive content analysis through a global social policy and gendered coloniality lens. Our research documents silence, ignorance, avoidance, and possible over-interpretation of the PLGHA within the South African government. The colonialist politics of global redistribution created the grounds for gendered regulation, resulting in a fundamental undermining of reproductive rights. Ironically, the solution – advocacy and parliamentarian briefing regarding sexual and reproductive issues – is generally led by civil society, the bodies weakened by the PLGHA.

- Description: The 21 cm transition from neutral Hydrogen promises to be the best observational probe of the Epoch of Reionisation (EoR). It has driven the construction of the new generation of lowfrequency radio interferometric arrays, including the Hydrogen Epoch of Reionization Array (HERA). The main difficulty in measuring the 21 cm signal is the presence of bright foregrounds that require very accurate interferometric calibration. However, the non-smooth instrumental response of the antenna as a result of mutual coupling complicates the calibration process by introducing non-smooth calibration errors. Additionally, incomplete sky models are typically used in calibration due to the limited depth and resolution of current source catalogues. Combined with the instrumental response, the use of incomplete sky models during calibration can result in non-smooth calibration errors. These, overall, impart spectral structure on smooth foregrounds, leading to foreground power leakage into the EoR window. In this thesis we explored the use of fringe rate filters (Parsons et al., 2016) as a mean to mitigate calibration errors resulting from the effects of mutual coupling and the use of an incomplete sky model during calibration. We found that the use of a simple notch filter mitigates calibration errors reducing the foreground power leakage into the EoR window by a factor of ∼ 102. Thyagarajan et al. (2018) proposed the use of closure phase quantities as a means to detect the 21 cm signal, which has the advantage of being independent (to first order) from calibration errors and, therefore, bypasses the need for accurate calibration. In this thesis, we explore the impact of primary beam patterns affected by mutual coupling on the closure phase. We found that primary beams affected by mutual coupling lead to a leakage of foreground power into the EoR window, which can be up to ∼ 104 times and is mainly caused by the unsmooth spectral structure primary of primary beam sidelobes affected by mutual coupling. This power leakage was confined to k < 0.3 pseudo h Mpc−1. Lastly, we also proposed and demonstrated an analysis technique that can be used to derive a flux scale correction in post-calibrated HERA data. We found that after applying flux scale correction to calibrated HERA data, the bandpass error reduces significantly, with an improvement of 6%. The derived flux scale correction was antenna-independent, and it can be applied to fix the overall visibility spectrum scale of H4C data post-calibration in a fashion similar to Jacobs et al. (2013). , Thesis (PhD) -- Faculty of Science, Physics and Electronics, 2024

Critiques have included heteronormative biases, an emphasis on danger, disease and damage, a reinforcement of gendered binaries, and the lack of pleasure or well-being discourses. In contrast, our research focused on the unexpected moments teachers experience, i.e., the ethical, emotional or psychological challenges they encounter in their interactions with learners.

- Description: This study investigated the rise of ‘violent-non state actors’ in South Africa, with specific focus on the taxi industry in the Eastern Cape Province. Contemporary South Africa has been a playground for violent non-state actors often evidenced by sporadic service delivery protests and gun violence in public spaces. Many authors attribute these to the failure of the state to provide public services such as security, water, employment, etc. Amongst these non-state actors, are taxi associations called mother-bodies. The deregulation of the taxi industry by the then apartheid government in 1987 resulted in the exponential inflow of previously oppressed black people into the taxi industry, which had now become the most accessible form of informal business for previously disadvantaged people. This resulted in the formation of many mother-bodies that subsequently became ‘law unto themselves’ due to the absence of formal state regulation amongst other things. Since then, violent conflicts amongst these mother bodies have become the order of the day. The study sought to determine the commuter’s perspectives about the taxi industry and violence in the Eastern Cape Province, to determine ways in which the taxi industry has challenged the monopoly of the state over the legitimate use of force and to explore the reasons why taxi violence has largely gone unchecked by the state. Part of the key findings of the study were that there is a general sense of fear and insecurity amongst commuters especially female commuters who use taxis. Various cases of sexual assault, intimidation and psychological traumas caused by exposure to violence amongst commuters have been reported. It has also been determined that in order to effectively challenge the monopoly of the state over the legitimate use force, some taxi operators have resorted to the use of self created laws to intimidate their competitors, use of mafia-like tactics, extortion and coercion amongst other things in order to impose monopoly over some lucrative routes, individuals and associations. In resolving some of these challenges, the study inter alia recommends for the formalization of the taxi industry by government, which will result in the subsidisation of the industry. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2024

- Description: Understanding resource use of invasive species provides insights for predicting and mitigating their impacts on biodiversity. We explored the predictability of diet of the invasive common warthog by describing and comparing the diet of warthog populations from two semi-arid, invaded sites, Addo Elephant National Park (AMC), and Great Fish River Nature Reserve (GFRNR), Eastern Cape, South Africa. These sites are both dominated by the Subtropical Thicket biome, but differ in vegetation type. We used forage availability to estimate diet preferences at AMC. We predicted that warthog would consume grass in invaded landscapes. Additionally, we predicted that the diet at one invaded site would predict this at another invaded site. As predicted, warthog mainly consumed grass at both sites (AMC – 87.4%, GFRNR – 88.5%), eating few woody plants, succulents, and forbs. Cynodon dactylon was the most consumed species in AMC, in GFRNR this was Eragrostis curvula and Cymbopogon pospichilii. Our ability to predict the diet between sites was constrained by variation in the plant species consumed. We found strong relationships between the consumption of preferred plant species at AMC and their consumption at GFRNR. We show that warthogs are specialised grazers outside their native range and thus can be expected to impact grass communities in invaded areas, especially preferred grass species. Thus, conservation managers need to monitor grasses in areas invaded by warthog to better detect and manage their impacts.

- Description: Protected areas are becoming increasingly isolated refugia for large carnivores but remain critical for their survival. Spotted hyaenas (Crocuta crocuta) are important members of the African large carnivore guild but, like other members of the guild, routinely come into conflict with people because of their large home ranges that are not always confined to protected areas. To effectively conserve spotted hyaena populations, it is paramount to monitor their abundance through reliable and cost-effective techniques. We estimated the density of spotted hyaenas in Hluhluwe–iMfolozi Park (HiP), South Africa using camera trap images and a spatially explicit capture-recapture (SECR) framework between 2013 and 2018. We estimated an average of 18.29 ± 3.27 spotted hyaenas per 100 km2 between 2013 and 2018, with an annual estimated high of 20.83/100 km2 in 2014 and a low of 11.98/100 km2 in 2015. Our results demonstrate that camera trap by-catch data can be used for estimating spotted hyaena densities over time. We believe that given the widespread use and deployment of camera traps across Africa, collaborative efforts to use existing data to improve regional and continental estimates and population trends for spotted hyaenas should be a priority.

- Description: Women who sell sex (WSS) are vulnerable to violence. We present a scoping review of the last decade of research on the prevalence and incidence of, factors associated with, and services regarding violence against WSS in Eastern and Southern African (ESA). A systematic search of various databases resulted in 20 papers being reviewed. Inclusion criteria, applied by the first two authors, were as follows: empirical papers, key research problem is violence against WSS, and conducted in ESA countries. The lifetime prevalence of violence revealed in the studies ranged from 21% to 82%. A pattern of generalized violence against WSS from paying clients, male partners, strangers, family members, friends/acquaintances, and the authorities emerged. Factors associated with violence included the context within which the sex work occurs, alcohol use, type of sex exchange interactions, and personal factors (low education, low income, marriage, youth, high client volume, time in sex work, forced sexual debut, and internalized sex work stigma). WSS seldom access services after violence. Evaluations of two programs, a woman-focused HIV intervention, and the Diagonal Interventions to Fast-Forward Reproductive Health project, showed improvements in gender-based violence services. Findings suggest that targeted programmes should be paired with improving general health services and focus on promoting collective agency among WSS.

- Description: Counselling psychology in South Africa has recently emerged from a tumultuous period, stemming from regulatory efforts in 2011, which negatively impacted on the profession’s status and viability. While the definition and scope of counselling psychology arguably demonstrate improvements in aligning with global practices, concerns persist surrounding the work opportunities and professional experiences of counselling psychologists, particularly those in the early stages of their careers. This study aimed to gain an in-depth understanding of the professional experiences of early career counselling psychologists in South Africa. The pool of participants were 10 early career counselling psychologists (females = 7, males = 3, period in service = 1–10 years). The participants completed semi-structured interviews on their early career professional experiences, as well as the meanings they attributed to these experiences. An interpretative phenomenological analysis of the data revealed three group experiential themes: (1) the complexity of finding and securing work; (2) navigating an array of personal, professional, and systemic challenges, and (3) self-acquiring support. The findings suggest that despite the unique and valuable skills and knowledge counselling psychologists possess, the participants struggled to successfully transition into the workforce, resulting in feelings of anxiety, frustration, and professional disillusionment. The findings indicate enhanced support is needed at various levels to address the needs and bolster the wellbeing, utilisation, and retention of counselling psychologists in their transition into the South African workforce.

- Description: The objective of the study was to investigate how postgraduate research supervision practices may contribute to the improvement of publication output at the selected university. Drawing from extensive literature, the significance of establishing strong supervisor-supervisee relationships was emphasised as paramount to the success of postgraduate research study. In conjunction with the theoretical framework, the research used a well-structured inductive approach, which took into account the context where the research took place, anchored by a case study as it provides tools for the researcher to study complex phenomena within the context of the study. The sample consisted of 24 participants who were purposefully selected from the selected faculty in the selected university. Data were collected through semi-structured interviews, which were conducted by the researcher in person and detailed procedures, ensuring the credibility and reliability of the study. Strict confidentiality measures were in place, ensuring participants’ anonymity and the safeguarding of their responses, fostering a trustworthy environment for honest revelations. Data were analysed and interpreted with ATLAS.ti software. Data analysis was carried out systematically, identifying themes and subthemes that answered the central research question. This rigorous analysis led to the discovery of several crucial findings. There was a notable call for academic support mechanisms like mentorship, advising and research supervision to bolster postgraduate research outputs, especially in remote universities. Financial constraints and barriers to attending research seminars and conferences emerged as significant hurdles, stressing the need for effective strategies to overcome these challenges. iii In-depth discussions revealed the criticality of fostering healthy supervisor-supervisee relationships from a development’s inception, highlighting the pivotal role of open communication. The study also identified supervisors’ need for institutional support in acquiring the necessary educational capabilities to efficiently mentor postgraduate students. Furthermore, emphasis was placed on the importance of enhancing postgraduate students’ professional writing skills for publication. However, the study did not ignore the challenges faced by research supervisors. Heavy workloads, time constraints and high expectations emerged as considerable stressors. Among the recommendations, the study called for institutional assistance in obtaining the essential educational competencies to effectively guide postgraduate students. Attention to the dire need for improved support systems, research infrastructure, incentives for supervisors and streamlined research procedures. In summation, this research underscores the significance of continuous monitoring, evaluation and engagement strategies to foster an environment conducive to advanced postgraduate research supervision and publication growth Key words: Postgraduate supervision, research publication, postgraduate students, Historically Disadvantaged University. , Thesis (D.Ed) -- Faculty of Education, 2024
