- 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: 7de Laan uses primarily Afrikaans and English, with indigenous languages used instantly; My Desire is dubbed from Hindi to English only. The chapter aims to demonstrate how using English and Afrikaans in 7de Laan and dubbing Hindi into English in My Desire promote ideologies of Colonial-Apartheid linguistic order. The chapter argues that the use of Afrikaans in 7de Laan and English dubbing in My Desire are primarily homogenous. When indigenous languages are excluded in 7de Laan and dubbing in My Desire, it is not just about 7de Laan being an Afrikaans soap opera or My Desire promoting English over indigenous languages. This is also about creating an environment where the Colonial-Apartheid linguistic order can be established and sold to viewers. It is about rejecting the post-Apartheid notion of the Rainbow Nation.

- 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.

Scholars constantly embark on this fascinating journey encompassing various topics, including lan-guage preservation, cultural representation, media policy and audience reception. Research has proven that media products in indigenous African languages are growing exponentially, with media creatives continuing to see the need to produce content in these languages. Films, songs, soap operas and digital media tools increasingly endorse African indigenous languages as their primary mode of de-livery, challenging and unsettling the monopoly that Indo-european languages have enjoyed in these spaces.

- 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: This chapter deals with indigenous radio broadcasting by considering a Setswana language community radio station as a case study. The aim is to examine the role these stations have played in South Africa over the decades and their contribution to revitalising indigenous languages. The study draws influence from indigenous radio stations as a catalyst for protecting and preserving languages from total extinction. The station considered is Vaaltar FM. Using the theories of language revitalisation and translanguaging, the chapter will discuss strategies endorsed by indigenous radio stations in South Africa to revitalise indigenous languages. While some radio stations, especially public service broadcasting radio stations, revitalise standard indigenous languages, some community and commercial radio stations, such as Vaaltar FM, do the same by employing complex situated, processual and interactional communicative practices such as translanguaging. These differing approaches expose the long-standing tension faced by radio stations aimed at indigenous-speaking South Africans regarding whether they remain traditional in their approach or adapt with the times and incorporate modernised elements that, to some, are a dilution of their cultural heritage.

- Description: Maize is Ethiopia’s dominant cereal crop regarding area coverage and production level. There are different varieties of maize in Ethiopia. Maize varieties are classified based on morphological features such as shape and size. Due to the nature of maize seed and its rotation variant, studies are still needed to identify Ethiopian maize seed varieties. With expert eyes, identification of maize seed varieties is difficult due to their similar morphological features and visual similarities. We proposed a hybrid feature-based maize variety identification model to solve this problem. For training and testing the model, images of each maize variety were collected from the adet agriculture and research center (AARC), Ethiopia. A multi-class support vector machine (MCSVM) classifier was employed on a hybrid of handcrafted (ie, gabor and histogram of oriented gradients) and convolutional neural network (CNN)-based feature selection techniques and achieved an overall classification accuracy of 99%.

Pandemic revealed disparities and significant gaps in access to public health information for those not proficient in English, potentially leading to the exclusion of indigenous language speakers and minority communities from issues of national interest, including vital COVID-19 updates. This chapter examines the case study of Rhodes University in the Eastern Cape, South Africa and explores the institution's language policies and practices during the pandemic. The institution grapples with linguistic diversity, where English is the primary language of teaching and administration. The study explores language, public health communication, and inclusion at Rhodes University. It seeks to find linguistic and cultural contestations during this time by evaluating the university's response to the pandemic through language. The study uses document analysis to understand how Rhodes University's language practices impacted public health communication during the pandemic.

- Description: In this chapter, a group of student-researchers and their lecturer discuss their findings relating to a podcasting intervention which took place in an Ethnomusicology thirdand fourth-year class at Rhodes University in Makhanda, Eastern Cape, South Africa. As part of a larger project, in which the class explored podcasting in general, they experimented with the medium in order to ascertain in what role it could be used as a learning and teaching aid in tertiary pedagogy. Audio recordings of the lecturer discussing journal articles relating to the module were sent to students. They listened to and used them in different scenarios, orchestrated to research their effectiveness in diverse learning and teaching situations. Using a qualitative case study research design methodology, the student researchers and their lecturer present these findings through a participatory lens. They analyse the podcasts’ efficacy and limitations from various perspectives through coding responses. Finally, they discuss future usage of the medium as a way to enhance students’ understanding of academic readings.

- Description: In this chapter, a group of student-researchers and their lecturer discuss their findings relating to a podcasting intervention which took place in an Ethnomusicology thirdand fourth-year class at Rhodes University in Makhanda, Eastern Cape, South Africa. As part of a larger project, in which the class explored podcasting in general, they experimented with the medium in order to ascertain in what role it could be used as a learning and teaching aid in tertiary pedagogy. Audio recordings of the lecturer discussing journal articles relating to the module were sent to students. They listened to and used them in different scenarios, orchestrated to research their effectiveness in diverse learning and teaching situations. Using a qualitative case study research design methodology, the student researchers and their lecturer present these findings through a participatory lens. They analyse the podcasts’ efficacy and limitations from various perspectives through coding responses. Finally, they discuss future usage of the medium as a way to enhance students’ understanding of academic readings.

- 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

- Description: Research on school-based sexuality education in South Africa, taught within Life Orientation (LO), has mainly focused on learners’ responses, how teachers approach the subject, and the curriculum content. 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: The significance of language policies cannot be overlooked, particularly in countries where political ideologies influence perceptions about the use of various languages in various domains. Due to political influence certain languages are regarded as ‘languages of the state’and others are perceived to be ‘languages in the state’. Language practices during apartheid in South Africa were very influential in deciding the plight of indigenous African languages. During this period, indigenous African languages were subjected to suppression, wherein an exoglossic lan-guage policy remained intact. Mekoa (2020) explicates that language was used as an instrument of domination or subjugation during apart-heid and colonization. Mekoa (2020) further indicates that in South Afri-ca, indigenous African languages were denigrated and marginalized through legislative structures of the apartheid government.

- Description: This study presents a novel approach to understanding the economic freedom fighters (EFF) role in South African politics. The party has been called populist, fascist, and a threat to South Africa's democracy. This study was conducted through virtual ethnography research on the role of the EFF in South Africa's politics and presents the research findings here to understand if the EFF is merely populist, a threat to democracy, or encouraging citizens' political participation. The study's findings indicate that the EFF uses populist stances to attract supporters and voters to the party. But unlike the views of some commentators and scholars, the study presents different findings regarding the EFF's populist attitudes in the country's democracy. While some see such populist stances as a threat to democracy, the study views it as the party's advantage, among others, to encourage citizen political participation.

- Description: The use of protective netting is becoming an increasingly popular practice in the citrus industry in South Africa. However, data on its effects on biotic factors, particularly insect pests, are limited. This study focused on the effect nets have on key citrus pests in the Eastern Cape province. Orchards under nets and open orchards, of similar cultivars, ages and management practices, were monitored at several sites over two seasons for pest infestation and damage. Weekly monitoring was conducted for Thaumatotibia leucotreta infestation. Other pests were monitored either monthly or once a season.
