  • 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: The extant academic literature in the field of regional International Relations has paid little attention to non-state actors’ organizational relations in building region-ness. Yet, the region offers sets of organizational relations outside, alongside, and as part of the formal regional state structures to do with gender, which offer insights into non-state regional relations and thus help to fill the lacunae in the field and facilitate understanding of the regional dynamic of international relations. This article examines how organizational relations of non-state actors in gender security play out in the Southern African Development Community (SADC) region. It highlights the shortcomings of the inter-governmental approach to international relations pursued by various scholars. Drawing on interviews with representatives of NGOs, governments, the SADC, and annual reports, as well as the academic literature, it argues for a socio-historical approach to understanding regional organization and transnationalism, which considers African agency in building region-ness.

  • Description: Egeria densa is a submerged aquatic weed that can grow into dense monocultures in rivers and dams in South Africa, which negatively affects ecosystem functioning and services. The biological control agent Hydrellia egeriae Rodrigues-Júnior (Diptera: Ephydridae) was first released against Egeria densa Planchon (Hydrocharitaceae) in South Africa in 2018. Biotic resistance in an introduced range can have negative impacts on the ability of a biological control agent to establish and exert top-down pressure. Dipteran and lepidopteran species that are used as biological control agents are often susceptible to higher levels of parasitism in their introduced range than biological control agents from other insect orders. In addition, ecological analogues that are present in South Africa, make H. egeriae particularly vulnerable to biotic resistance. Considering this, post-release surveys were conducted to investigate if native parasitoids will extend their host range to include H. egeriae. Chaenusa seminervata van Achterberg, C. anervata van Achterberg (Braconidae: Alysiinae: Dacnusini) and Ademon lagarosiphonae van Achterberg (Braconidae: Opiinae) were reared from field-collected H. egeriae pupae, within a year of its release. These braconid parasitoids were previously recorded from a native herbivore, Hydrellia lagarosiphon Deeming (Diptera: Ephydridae).

  • Description: The growth of technology has made the Internet an essential tool in so-ciety. Scholars have argued that the Internet supports a more delibera-tive democracy. However, scholars have also raised concerns about the role of the Internet in political matters. While scholars agree that the Internet has facilitated broader public discussion, in many regards, its ‘virtual public sphere’still mirrors existing social structures. Twitter has become a common social media platform for many South Africans. This has led to a virtual community of Twitter users engaged in real-time dis-courses primarily related to Black South Africans. Black Twitter in South Africa is used for social, political, and economic motivations. This study argues for the practice of Black Twitter as a digital counterpublic in South Africa. The aim is to spotlight how black people in South Africa have used Black Twitter as a digital counterpublic for the marginalized groups within South Africa. The research will investigate the potential challenges and opportunities associated with Black Twitter functioning as a digital counterpublic. Utilizing digital ethnography, the study gath-ered a dataset of tweets from Black Twitter in 2022, focusing on those addressing social, political, and economic issues. More than 700,000 tweets were identified under these specific thematic hashtags.

  • Description: Bereavement is something that we experience in one way or another. It involves many steps from one culture to the other. Many scholars have documented the role of social media tools in bereavement processes. In this study, I look at the challenges and opportunities offered by Fa-cebook during bereavement, especially in a community that is still tradi-tional and has yet to fully comprehend the importance of social media, particularly in matters considered sacred. The study used interviews with residents from Taung to collect data. Thematic analysis was used to analyze the collected data from the interviews. The study findings indicate some challenges associated with bereavement on Facebook: emotional shock, lack of sensitivity, misinformation, and cultural dilution. There are also opportunities: fast news sharing, ongoing emotional support, and sharing of memories. The study argues that the findings should expand our understanding and knowledge of bereavement in some African cultures and use social media tools to complement and not destroy African beliefs and practices.

  • Description: Taxonomic identification of arbuscular mycorrhizal (AM) fungal spores extracted directly from the field is sometimes difficult because spores are often degraded or parasitized by other organisms. Single-spore inoculation of a suitable host plant allows for establishing monosporic cultures of AM fungi. This study aimed to propagate AM fungal spores isolated from maize soil using single spores for morphological characterization. First, trap cultures were established to trigger the sporulation of AM fungal species. Second, trap cultures were established with individual morphotypes by picking up only one spore under a dissecting microscope and transferring it to a small triangle of sterilized filter paper, which was then carefully inoculated below a root from germinated sorghum seeds in each pot and covered with a sterile substrate. All pots were placed in sunbags and maintained in a plant growth room for 120 days.

  • 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: The numbers of Common Starlings Sturnus vulgaris and indigenous starling species, as well as a subset of other common birds, were recorded from October 2006 to January 2020 at 72 point-count sites along four routes (two urban and two rural) in the Eastern Cape Province of South African. In the rural habitat, Common Starlings were localised at buildings; in the urban habitat, there was no clear indication that their presence influenced the occurrence or abundance of the Red-winged Starling Onychognathus morio, a native species which has colonised towns and nests on buildings. In this region there is little evidence that Common Starlings invade areas that have not been heavily modified by human activities.

  • 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: On the occasion of 30 years of South African democracy, we reflect on the current state of Psychology research in South Africa. We conducted a situational analysis of all papers appearing in the South African Journal of Psychology (SAJP) and abstracts in PsycINFO with the keyword ‘South Africa’ over the last 5 years and compared the results with a previous review that used the same methodology. Findings show an increase in papers using ‘hard’ science approaches and a decrease in systems-oriented theories. Assessment remains a major topic. While COVID-19 and climate change featured, there remains a lack of or low focus on several key psycho-social issues experienced by South Africans. People living in poorer provinces and young and older people are under-represented in knowledge production. Collaborations or comparisons with other African or South American countries have decreased. Positively, production is being spearheaded by South African scholars or people affiliated with South African institutions. Using a decolonising lens that foregrounds epistemic justice, we conclude that substantial work remains to be done for knowledge production in South African Psychology to fulfil the decolonising imperative of distributive epistemic justice.

  • Description: The British, French, and Portuguese regimes colonized most African countries. This colonization took away African languages, cultures, religions, and practices, only to replace them with colonial traditions. Decolonization debates are now rife in South Africa: decolonizing higher education, the economy, the law, and the justice system. All these debates and attempts are made to achieve equity and justice in the country. To contribute to these debates, this chapter examines how journalism education can be decolonized in South Africa from a sociolinguistic perspective. To achieve its aim, the chapter will review course descriptions of journalism curriculums at three universities in South Africa that offer journalism education and possible ways to decolonize the curriculums from the sociolinguistics perspectives. The chapter has concluded that sociolinguistics is critical in decolonizing journalism education. Journalism is a verbal medium; it uses language to communicate. Hence, it is essential for journalism curriculums in South Africa to teach students that language and identity can influence journalism practice to reflect its context and speak to its people in a language and forms that they understand.

  • Description: Out-of-school comprehensive sexuality education (CSE) Re-search on abortion counselling generally uses retrospective interviewing regarding providers’ and users’ experiences. In this article we explore how requests for abortion are made and received in real time in (officially non-mandatory) pre-abortion counselling conducted by nurses and counsellors in South African public abortion clinics. To capture turn-by-turn interactions, we recorded, using consecutive sampling, 28 sessions at three abortion clinics in 2017/2018. No researcher was present. Conversation analysis, based on an ethnomethodological paradigm, was used to understand the conversational projects of the sessions and to outline how the provider and user oriented to the request for an abortion as a conversational task.

  • 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.
