- Description: South Africa's post-school education and training (PSET) system plays an important role in addressing historical inequalities and preparing youth for the labour market. Technical and vocational education and training (TVET) colleges have seen rising female enrolment, including in traditionally male-dominated fields like Engineering. This study examines whether women's increased participation in TVET programmes translates into equal labour market opportunities. Using administrative enrolment data and a tracer study of TVET completers, findings show that female completers face significantly higher unemployment rates than men, unrelated to the over-representation in Business Studies or services programmes. Additionally, women earn 22% less than men, even after accounting for study choices and qualification levels. While challenges remain in ensuring gender parity, the increasing presence of women in male-dominated fields signals progress. Efforts must focus on translating these gains into equitable employment outcomes.

- Description: The desire of Gukurahundi survivors for cultural platforms that enable them to discuss, mourn, and commemorate their loved ones is now very loud in Zimbabwe’s Matabeleland and Midlands provinces. While community-based organisations have provided platforms for Gukurahundi survivors, the children of survivors, and academics to interface and interact, the government’s gatekeeping processes remain a challenge for the community-wide memorialisation and documentation of the genocide. In this conceptual paper, I frame Gukurahundi as a meteorological event within a general Zimbabwean cultural context, foregrounding the desecration of the Ndebele people’s cultural practices, rituals, and ceremonies. Drawing from the documented legacies of this cultural violence within Matabeleland and south-western parts of the Midlands, through videos and the literature, I argue that this cultural violence resulted in the silencing of the remembrance of Gukurahundi, which remains critical to the resolution of the stand-off between the ZANU-PF government and the communities. In this paper, I further argue that this ecological symbolism provided a justification and legitimated direct brutal violence on presumed ZAPU and ex-ZPRA veterans who were largely Ndebele-speaking or of ethnic descent. Finally, I argue that it is not that the absence of alternative narratives but the sociopolitical and cultural environment that constrains these from being available and implemented.

- Description: The belief that persons with mental illness are dangerous and unpredictable has been noted in several studies. This perception is often associated with fear in those who hold this belief. The unpredictable nature of mental illness may also be a factor in how health care professionals react to and provide care for mentally ill patients. This may lead to an increase in negative attitudes towards mentally ill patients thereby resulting in negative patient outcomes. In South Africa (SA) there is paucity of literature regarding attitudes towards mental illness. Most studies done in SA have focused on patients’ experience of stigma and community attitudes towards people with mental illness. This research was conducted against this background to assess health care professionals’ attitudes towards patients with mental illness at the study site, which was at Nelson Mandela Central Hospital, in the Eastern Cape.

- 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: The Employment Equity Act (55 of 1998) is a legislation that was formulated post apartheid by the South African government to overcome the inequalities of the past and unfair discrimination against designated groups. Effective implementation and constant monitoring of legislation is an important tool to track the outcomes and assist future policymakers as a reference to addressing similar issues. The study intends to investigate the implications of implementing the Employment Equity Act (55 of 1998) at Winnie Madikizela-Mandela Local Municipality. A qualitative research method was employed, and semi-structured interviews were conducted which solicited questionnaires from the selected sample. The study focuses on the perspective of employees on how they perceive the study area’s Employment Equity Plan. The results of the study demonstrate positive implications of the implementation process of the prescribed Act such as fairness and improved opportunities; however, it also outlines the challenges of financial constraints, lack of diversity, poor communication, and a need for education and awareness on the Act. The municipality has drawn strategies to address the identified challenges. It was found that the majority of employees in the municipality are informed of the Act and know what constitutes fair and unfair treatment though some are clueless. The recommendations to enhance and ensure more positive results will be shared with the sampled participants to ensure that they work on their EEP. , Degree: M. Public Administration

- Description: The inclusion of indigenous knowledge into the curricula of natural science courses remains contentious. In this paper I use critical realism to show the relationship between these two forms of knowledge. An engagement with both knowledge structures could afford better pedagogy and assessment. In addition, the engagement with indigenous knowledge allows for the development of 'knower awareness' in the practice of science. Meaningful engagement with indigenous knowledge could therefore enhance science education, whilst making visible the socio-cultural relevance to students.

- Description: The need for more attention to the social and human dimensions in global change sciences and natural resources management requires in-depth understandings of transformative approaches and processes. More inclusive and systemic approaches are needed that embrace complexity and support transformative learning, shifts in power relations, collective and relational agency and structural transformations for adaptive and innovative governance. Scientific understanding of how such change can be brought about is still limited. In this paper, which sets the scene for this Special Issue, we develop a conceptual framework for analyzing transformative processes across a range of diverse cases. Aspects of the conceptual framework are applied, tested and elaborated in three following papers in the Special Issue, deepening understanding of how transformative change in complex social-ecological systems may originate at nexus boundary zones such as that portrayed by the water-food-energy nexus. Specifically, the paper conceptually elaborates four iteratively related dynamics of transformative learning, transforming power relations, transformative agency and transforming structures which intersect in transformation processes. The perspectives offer tools for cross case analysis in the longer term, but also tools for supporting co-engaged, generative research processes.

- 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%.

- Description: The South African pharmaceutical sector is Africa's largest and most advanced but heavily depends on imported products and active pharmaceutical ingredients to meet its demands. The status quo is due to low intra-industry trade, which is necessary to induce innovation and technological progress essential for accelerating local production, export growth and reducing dependence on imports. AIM: The primary objective of this article was to examine intra-industry trade in South Africa's pharmaceutical sector and subsequently, total factor productivity (TFP) as a key driver of intra-industry trade. Intra-industry trade was measured using data obtained from the United Nations Conference on Trade and Development databases, while the TFP was measured using data from the South African Reserve Bank (SARB) covering 2001-2021.

- Description: The emergency of carbapenem-resistant Enterobacterales is prevalent and poses a significant threat to health systems worldwide. The European Center for Disease Control and Prevention has reported a mortality rate of about 50% in patients with CRE bloodstream infections. This study aimed to conduct a molecular analysis of tigecycline resistance in 100 CRE in clinical isolates from Mthatha and surrounding hospitals. The results showed a notable high prevalence of CRE infections in neonatal, male surgical, and maternal and pediatric wards, predominantly driven by Klebsiella spp. (53.4%), followed by Enterobacter spp. (20.5 %), then Escherichia coli (6.7%). The present study performed tigecycline AST using an E-test on 100 CRE hospital isolates., A total of 92.8 % CRE was susceptible to tigecycline, 1.6 % intermediate resistant to tigecycline, and 5.8 % resistant to tigecycline. A multiplex SYBR green-based PCR assay for rapid detection of tet(X) and its variants, including tet(X1), tet(X2), and high-level tigecycline resistance genes tet(X3), tet(X4), and tet(X5) were developed. The results in 100 CRE clinical isolates studied indicated that there were no tet (X) gene detected that was responsible for tigecycline resistance. The risk factors associated with tigecycline resistance in CRE include age, pre-exposure to antibiotics, prolonged hospitalization, and undergoing invasive procedures indicated by strong r2 =0.9501. CRE gradually evolves, posing a significant threat to patients of all ages. Early detection of carbapenemase production in clinical infections, carriage states, or both is essential to prevent hospital based outbreaks. As using Tigecycline is the last line of treatment for CRE infection, the high rate of tigecycline resistance in this study is alarming for the healthcare system in South Africa. Tigecycline combination therapy is recommended when treating critically ill patients. Tet (X) genes are not responsible for tigecycline resistance in the sample of this study. The risk factors associated with tigecycline resistance in CRE include age, pre exposure to antibiotics, prolonged hospitalization, and undergoing invasive procedures. , Degree: M.

- Description: Maize (Zea mays) is essential for global food security, providing sustenance to billions, especially in developing countries. With the global population projected to reach 9.7 billion by 2050, maize demand will significantly increase, requiring improved agricultural practices and resilient varieties. However, drought is a major threat to maize production, particularly in semi-arid regions like South Africa, where rainfall is often scarce. This study aims at investigating the morphological, physiological, and biochemical responses of five maize cultivars—CY2 DKC72-76BR, CY3 DKC74-26R, CW1 DKC75-65BR, CY1 DKC71-44B, and CW3 DKC78-45BRGEN—with the goal of identifying specific traits indicative of drought tolerance. The plants were subjected to well-watered and water-deprived conditions for 21 days. Key parameters, including shoot and root growth, relative water content (RWC), H2O2, lipid peroxidation, and antioxidant enzymes (ascorbate peroxidase and superoxide dismutase), were measured to assess drought tolerance. The results revealed that drought stress significantly reduced shoot and root lengths, weights, and RWC of water-deprived cultivars when compared to the well-watered cultivars. Elevated hydrogen peroxide (H2O2) and lipid peroxidation indicated increased oxidative stress under water deprivation. Drought tolerant varieties exhibited higher antioxidant enzyme activity, suggesting a potential mitigation of oxidative stress… , Degree: M.Botany

- Description: This research investigates the challenges faced by Ntabankulu Local Municipality as a result of municipal demarcation. The post-demarcation process in South Africa has often been overlooked by the government, leading to negative repercussions in local municipalities, particularly in service provision due to boundary redrawing. However, these boundary changes also present significant opportunities for local development, especially as they aim to dismantle the apartheid legacy of racial oppression and unequal service provision. The study employs a qualitative research approach, which was deemed appropriate for achieving the research objectives. The sample size consisted of 25 participants, including 5 community leaders, 5 municipal authorities from Ntabankulu, 5 general community members, 5 traditional leaders, and 5 representatives from civil society organisations. A simple sampling method was used to select participants, and open-ended interview questions were administered. Based on the findings, this study recommends that Ntabankulu conduct thorough and timely consultations with all stakeholders and foster the development of communication links between affected communities following the demarcation process. , Degree: M.

Despite significant legislative support for inclusive governance, public participation in local government remains largely symbolic, often failing to address women's unique challenges, particularly in marginalized and rural communities. Drawing on an extensive review of South African and African studies, this research examines the structural, socio-economic, and logistical barriers that limit women’s meaningful engagement in local governance, especially in service delivery.

- Description: Knowledge-making in universities is shaped by conventions that neglect and/or suppress less conventional kinds of knowledge that may hold viable solutions to society’s problems. Knowledge always has political interests, and close-up research on knowledge-making can liberate marginalized ideas, by exposing how they push against and beyond conventional perspectives and mutations. African feminist theoretical ideas are used to examine three different platforms for knowledge-making: one research project and two courses that were taught. The African feminist praxis is demonstrated through two main processes – reflection and communal knowledge-making – which infuse the methodology and pedagogy of the three platforms. The article shows how they transgress the conventions to bring about inclusive and generative knowledge-making. They provide strategies for future research and teaching experiments, demonstrating ways in which African Feminist ideas can have transformative effects beyond their own margins.

- Description: Out-of-school comprehensive sexuality education (CSE) programmes are viewed by UNFPA as important in empowering youth. These programmes may, however, be critiqued for, firstly, inadvertently equating empowerment with individual agency to the exclusion of social justice; and, secondly, using the word empowerment as a self-evident signifier. We propose that empowerment be conceptualised within a critical sexual and reproductive citizenship (CSRC) framework that draws on feminist and queer re-workings of the principles of citizenship. To operationalise this conceptualisation, we developed the Masizixhobise toolkit from the five key issues outlined in the CSRC framework. The aim of the toolkit is to aid in the design and refinement of theoretically embedded empowerment CSE programmes. In this paper, we demonstrate the use of the toolkit. To do so, we analyse the Partners in Sexual Health’s (PSH) Sexual and Reproductive Health and Rights facilitator’s manual. A template analysis was conducted on this manual using a priori of themes from the toolkit. We sift through the PSH manual’s alignments or misalignments with the CSRC framework and make recommendations for enhancing the empowerment components of the manual. This example may assist others in designing and refining theoretically embedded and socially just youth empowerment CSE programmes.

- Description: The taking and archiving of accurate record-keeping is an essential part of caregiving in health care. There is extensive evidence that record-keeping systems are affected by systemic problems that impact healthcare provision globally and in South Africa, particularly in public healthcare. Human Factors and Ergonomics (HFE) has been applied in healthcare settings to address these systemic challenges, including those related to record keeping, but not in South Africa. With participation being a critical element of HFE, a Community-Based Participatory Research (CBPR) framework can but has not been used to understand and optimise systems such as those linked to record keeping. This reflection provides an overview of how an HFE approach was applied, using a CBPR framework to understand the challenges affecting patient record-keeping in a clinic in Makhanda. Specifically, it provides insights into how CBPR was applied and reflections on this experience from both the researchers’ and collaborators' perspectives. The importance of patience and flexibility, empathy, constant feedback and consultation and listening to collaborators' and participants' contributions emerged as important lessons. The community collaborator also experienced the process positively, where she emphasised the empowering experience of being able to help guide and facilitate research, which, in turn, revealed challenges that affected the daily running of the clinic. The collaboration using the CBPR approach was a practical framework for applying several HFE approaches to understand the challenges around record keeping.

- Description: The notion of ‘sexual justice’ has gained traction in academic and policy arenas in recent years. This paper presents a scoping literature review of the regimes of truth, following Foucault, of ‘sexual justice’ appearing in the scientific literature from 2012 to 2022. Thirty-eight papers were coded using (1) content analysis of the studies’ central problematics, the programmes referred to, and institutional location(s); and (2) thematic analysis of how the notion was deployed. Central problematics centred on (1) critiques of, or alternatives to, dominant approaches to sexual and reproductive health; and (2) highlighting injustices. As such, ‘sexual justice’ is fighting for legitimacy in the truth stakes. There is a distinct paucity of papers tackling the translation of ‘sexual justice’ into practice. South Africa dominates as the site in which papers on ‘sexual justice’ have been produced, but there is a lack of South-South collaboration. Two themes were apparent around which conceptions of sexual justice cohere. Firstly, sexual justice is seen as a vital, yet politically ambivalent goal, with neoliberal co-optation of progressive rights agendas being warned against. Secondly, sexual justice is viewed as a means, in which sexual justice is described as having potential to repair established frameworks’ shortcomings and oppressive legacies.

- Description: This study focuses on N'Djili River catchment, a vital water source in Kinshasa that undergoes anthropogenic pressure and land use changes. The lower course of the river is particularly affected by uncontrolled urbanization, informal settlements, improper waste management practices, and vegetation degradation. The aim of this study is to determine the relationship between land use and river water quality in this catchment. Water samples were collected for physico-chemical and bacteriological analysis from 10 sampling sites along the river course. Land use categories were determined using Sentinel-2 land cover imageries and buffer scaling techniques. A redundancy analysis (RDA) was conducted to determine the relationship between land use categories and water quality variables.
