- Description: Home-based care facilities provide basic healthcare services to people too sick or frail to access formal clinics and hospitals. These facilities produce ‘healthcare risk waste’ which must be managed responsibly, and it is the work of Environmental Health Practitioners working within municipalities to ensure that the waste produced by home-based care facilities is managed in line with legislation. This paper presents a case study of a twenty-seven-month expansive learning intervention in a South African municipality that sought to transform its healthcare risk waste management practices. Limited knowledge and inadequate knowledge-sharing practices were identified as the main hindrances to effective waste management. The practitioner-researcher facilitated a series of inter-agency, formative intervention workshops with municipal employees and Community Health Workers using the Developmental Work Research methodology. These workshops strengthened both groups of practitioners’ knowledge of the ‘who, how, what, why and when’ that underpins effective healthcare risk waste management, and enabled ‘boundary crossing’ for practitioners to work across their specialist areas towards co-defining and analysing problems and constructing new solutions.

- Description: This paper reports on an international collaborative study that investigated how students from rural contexts negotiate the transition to university, and how prior cultural and educational experiences influence their higher education trajectories. A qualitative, participatory methodology was adopted, centred on co-researcher narratives, digital artefacts and discussions. Findings demonstrate how family and community, including religious, study, and self-help groups, influenced their transitions into higher education and journey through university and to their identities, agency and sense of belonging. The paper argues that university practices, values and norms need to acknowledge and incorporate all students’ prior experiences and histories and recognise their powerful contribution in working towards a decolonial higher education.

- Description: On 1 March 2019, the United Nations (UN) General Assembly (New York) declared 2021–2030 the “UN Decade on Ecosystem Restoration.” This call to action has the purpose of recognizing the need to massively accelerate global restoration of degraded ecosystems, to fight the climate heating crisis, enhance food security, provide clean water and protect biodiversity on the planet. The scale of restoration will be key; for example, the Bonn Challenge has the goal to restore 350 million km2 (almost the size of India) of degraded terrestrial ecosystems by 2030. However, international support for restoration of “blue” coastal ecosystems, which provide an impressive array of benefits to people, has lagged. Only the Global Mangrove Alliance (https://mangrovealliance.org/) comes close to the Bonn Challenge, with the aim of increasing the global area of mangroves by 20% by 2030. However, mangrove scientists have reservations about this target, voicing concerns that it is unrealistic and may prompt inappropriate practices in attempting to reach this target (Lee et al., 2019). The decade of ecosystem restoration declaration also coincides with the UN Decade of Ocean Science for Sustainable Development, which aims to reverse deterioration in ocean health. If executed in a holistic and coordinated manner, signatory nations could stand to deliver on both these UN calls to action.

- Description: Background: Pregnancy among adolescent girls in Bangladesh is high, with 66% of women under the age of 18 reporting a first birth; this issue is particularly acute in the northern region of Bangladesh, an area that is especially impoverished and where girls are at heightened risk. Using formative research, CARE USA examined the underlying social, individual and structural factors influencing married girls’ early first birth and participation in alternative opportunities (such as education or economic pursuits) in Bangladesh. Methods: In July of 2017, researchers conducted in-depth interviews of community members in two sub-districts of northern Bangladesh (Kurigram Sadar and Rajarhat). Participants (n = 127) included adolescent girls (both married and unmarredi), husbands of adolescent girls, influential adults in the girls’ lives, community leaders, and health providers. All interviews were transcribed, coded and organized using Dedoose software. Results: Participants recognize the health benefits of delaying first birth, but stigma around infertility and contraceptive use, pressure from mothers-in-law and health provider bias interfere with a girl’s ability to delay childbearing. Girls’ social isolation, lack of mobility or autonomy, and inability to envision alternatives to early motherhood compound the issue; provider bias may also prevent access to methods. While participants agree that pursuit of education and economic opportunities are important, better futures for girls do not necessarily supersede their marital obligations of childrearing and domestic chores. Conclusions: Findings indicate the need for a multi-level approach to delaying early birth and stimulating girls’ participation in economic and educational pursuits. Interventions must mitigate barriers to reproductive health care; train adolescent girls on viable economic activities; and provide educational opportunities for girls. Effective programs should also address contextual issues by including immediate members of the girls’ families, particularly the husband and mother-in-law.

- Description: There are limited approaches available that enable researchers and practitioners to conduct multiple case study comparisons of complex cases of collaboration in natural resource management and conservation. The absence of such tools is felt despite the fact that over the past several years a great deal of literature has reviewed the state of the science regarding collaboration. Much of this work is based on case studies of collaboration and highlights the importance of contextual variables, further complicating efforts to compare outcomes across case-study areas and the likely failure of approaches based on one size fits all generalizations. We expand on the standard overview of the field by identifying some of the challenges associated with managing complex systems with multiple resources, multiple stakeholder groups with diverse knowledges/understandings, and multiple objectives across multiple scales, i.e., multifaceted collaborative initiatives. We then elucidate how a realist methodology, within a critical realist framing, can support efforts to compare multiple case studies of such multifaceted initiatives. The methodology we propose considers the importance and impact of context for the origins, purpose, and success of multifaceted collaborative natural resource management and conservation initiatives in social-ecological systems.

- Description: In this era of precision medicine, insights into the resistance mechanism of drugs are integral for the development of potent therapeutics. Here, we sought to understand the contribution of four point mutations (N51I, C59R, S108N, and I164L) within the active site of the malaria parasite enzyme dihydrofolate reductase (DHFR) towards the resistance of the antimalarial drug pyrimethamine. Homology modeling was used to obtain full-length models of wild type (WT) and mutant DHFR. Molecular docking was employed to dock pyrimethamine onto the generated structures. Subsequent all-atom molecular dynamics (MD) simulations and binding free-energy computations highlighted that pyrimethamine’s stability and affinity inversely relates to the number of mutations within its binding site and, hence, resistance severity.

- Description: Provisioning ecosystem services of the Likangala River Catchment in southern Malawi are important for livelihoods of those living there. Remote sensing, participatory mapping and focus group discussions were used to explore the spatio-temporal changes and trade-ofs in land-cover change from 1984 to 2013, and how that afects provisioning ecosystem services in the area. Communities derive a number of provisioning ecosystem services from the catchment. Forty-eight species of edible wild animals (including birds), 28 species of edible wild plants and fungi, 22 species of medicinal plants, construction materials, ornamental fowers, frewood, honey, gum, reeds and thatch/weaving grasses were derived from the catchment and used by local communities.

- Description: Urban ecosystems provide goods and services critical to livelihood sustenance, environmental protection and sustainability. However, the potential role of some urban ecosystem services such as the provisioning services, to promote liveable cities and livelihood resilience is seldom considered. This study reports on the prevalence and pattern of wild plant foraging and uses in the towns of Potchefstroom and Thabazimbi, South Africa, based on a random sample of 374 households. Descriptive and inferential statistics were used for analysing data. Foraging wild plants was integral to livelihoods and traditions and provided household energy, dietary diversity, health, and cultural affirmation, among others. About 68 % of the respondents reported foraging wild plants, albeit at varying degrees between and within towns.

- Description: Gathering of uncultivated food from green spaces, also known as foraging, is observed in urban areas across the world, but the literature focuses predominantly on the global north. Our study examines the existing urban land management structure and its approach to urban foraging in the eastern coastal region of South Africa. Through interviews with municipal officials in nine cities, we identified different stakeholders and their roles in urban green space management. We then used network analysis to represent interactions and influence of these stakeholders, and environmental worldviews to determine organisational and perceptual barriers to and enablers of foraging in urban green spaces. The policy on urban green space management, as well as land managers themselves are amenable to the concept of foraging in public spaces. Lack of knowledge on wild indigenous species and sustainable offtake, ambiguous, coarse, or lacking policy, and normative views of pristine nature may hinder foraging. We recommend pathways for policy and stakeholder partnerships to incorporate sustainable foraging in their biodiversity conservation and land stewardship strategies.

- Description: Most sub-Saharan African countries are experiencing accelerating rates of urban migration, which bring with it many opportunities and challenges for migrating households, urban planners, governments and local and national economies. At the household level urbanisation may drive changes in the allocation of household labour and consequently social and economic relations. Yet how these are manifest in land-based livelihood strategies of arable cropping, livestock husbandry and the collection of wild products in urban settings has rarely been considered. Here we examine the changing participation rates in land-based livelihood activities by male- and female-headed households along the rural–urban continua of six sub-Saharan African secondary towns. To capture the gendered changes in land-based livelihood strategies along the urban–rural continuum, 1156 randomly selected households were sampled along transects radiating out from the urban through the periurban to rural surrounds. Participation in different land-based livelihood strategies was recorded by means of a questionnaire.

- Description: Metabolically induced drug-toxicity is a major cause of drug failure late in drug optimization phases. Accordingly, in vitro metabolic profiling of compounds is being introduced at earlier stages of the drug discovery pipeline. An increasingly common method to obtain these profiles is through overexpression of key CYP450 metabolic enzymes in immortalized liver cells, to generate competent hepatocyte surrogates. Enhanced cytotoxicity is presumed to be due to toxic metabolite production via the overexpressed enzyme. However, metabolically induced toxicity is a complex multi-parameter phenomenon and the potential background contribution to metabolism arising from the use of liver cells which endogenously express CYP450 isoforms is consistently overlooked. In this study, we sought to reduce the potential background interference by applying this methodology in kidney-derived HEK293 cells which lack endogenous CYP450 expression.

- Description: Snorkel and electrofishing surveys are the traditional baseline methods for fish surveys in clear headwater streams. However, action cameras provide a non-harmful alternative to monitor freshwater fish populations to develop informed conservation management initiatives. In this paper, estimates from photographs and videos from action cameras are compared with snorkel survey estimates of the density of a threatened endemic minnow species in a headwater stream, Eastern Cape, South Africa. Photograph-based relative abundances of fish summed over five microhabitats in each pool returned equivalent results to snorkel surveys, whereas the equivalent video-based abundance estimates were approximately 50% greater than the snorkel estimates. Therefore, photograph-derived estimates could be used as an alternative to snorkel surveys for fish population monitoring and habitat use studies in clear headwater streams.

- Description: This article is based on research conducted by a group of plurilingual postgraduate students from different disciplines who facilitated writing groups at the Centre for Postgraduate Studies at Rhodes University over the past two years. It is based on self-reflective writing of language biographies and aims to raise attention about, and to open up a discussion on, the impact of social and personal language practices. We approach the role of language not only as complex interrogation of academic identity, but also as sense of embodied self, an active element in the formation of geo- and body-politics of knowledge which has been highlighted in recent literature focussing on translanguaging in education and decolonising the curricula of Higher Education. Following selfguided research, we engaged in a critical reflection on the use of home languages in education and consulted relevant literature that argues for the inclusion of translanguaging practices in Higher Education. Our research, therefore, focuses on new epistemologies afforded by a shift away from the monolingual habitus and from the concept of multilingualism towards plurilingualism and translanguaging. Our data suggests that a plurilingual approach towards teaching and learning in Higher Education can afford epistemological access to learners across faculties and disciplines in Higher Education, and we argue that the role of languages of tuition in curricula need to be strategically re-evaluated.

- Description: The SDGs mark the clearest global acceptance yet that the previous approach to development was unsustainable. In VET, UNESCO has responded by developing a clear account of how a transformed VET must be part of a transformative approach to development. It argues that credible, comprehensive skills systems can be built that can support individuals, communities, and organisations to generate and maintain enhanced and just livelihood opportunities. However, the major current theoretical approaches to VET are not up to this challenge. In the context of Africa, we seek to address this problem through a presentation of literatures that contribute to the theorisation of this new vision. They agree that the world is not made up of atomised individuals guided by a “hidden hand”. Rather, reality is heavily structured within political economies that have emerged out of contestations and compromises in specific historical and geographical spaces. Thus, labour markets and education and training systems have arisen, characterised by inequalities and exclusions. These specific forms profoundly influence individuals’ and communities’ views about the value of different forms of learning and working. However, they do not fully define what individuals dream, think and do. Rather, a transformed and transformative VET for Africa is possible.

- Description: Background: Cities are at the fore of sustainability challenges of the twenty-first century, and many, particularly in Asia and Africa, are predominantly youthful spaces. Understanding young people's experiences in urban environments is therefore important as we strive to achieve both the Sustainable Development Goals and the Paris Agreement. Two amenities identified in the urban Sustainable Development Goal 11, transport and public and green space, are specifically recognised as applying to youth. Yet, there is little analysis that explicitly considers how youth experience these amenities across the Global North and South, and no current measures for understanding progress in youth experiences of green space and transport. Results: This paper provides a comparative analysis of young people's experiences with local transport and green space in seven diverse urban communities (Christchurch, New Zealand; Dhaka, Bangladesh; Lambeth/London, UK; Makhanda, South Africa; New Delhi, India; São Paulo, Brazil; and Yokohama, Japan). Our study contributes to a growing body of literature that seeks to listen to child and youth perspectives to understand their environmental experiences. We examine the 'affordances' young residents aged 12 to 24 years currently associate with green space and transport amenities. Affordances are defined here as the inter-relationships between what a local environment offers young people and their perceptions and actions. Drawing on focus groups and interviews conducted with 332 young people, we identify five affordances young people associate in relation to transport and public space across these diverse urban settings: (1) social inclusion and belonging; (2) autonomy; (3) physical comfort and security; (4) relaxation and reflection; and (5) health and fitness. Conclusions The paper contributes to growing interdisciplinary research interest in measuring affordances as a way to advance the Sustainable Development Goals in an urban context. In providing a comparative account of young people's experiences across diverse contexts, our discussion highlights how affordances in relation to transport or public and green space can help understand the multiple interconnections between the well-being of young people and sustainability. In particular, we argue that it is not merely the provision of transport or public and green space that matters, but the nuanced meaning of places and experiences as understood by local communities that needs to be recognised if we are to better support urban youth wellbeing and advance sustainable development goals.

- Description: In this paper, we outline a critical reparative justice/care approach to adolescent reproductive health as an alternative to the standard public health response to ‘teenage pregnancy’. Joining an increasing body of critical scholarship that calls for nuance in understanding reproduction amongst young people, we draw, in this paper, on data generated from an ethnographic study conducted in antenatal care units in an Eastern Cape township in South Africa. To illustrate the approach we propose, we home in on five case studies that highlight the variability of young women’s lives, the multiple injustices they experience, and the agency they demonstrate in negotiating their way through pregnancy and birth. Injustices evident in these cases centre on sexual violence, rape myths, education system failures, health system failures, shaming and stigmatising practices, socio-economic precariousness, absent male partners, and denial of services. We outline how the reparative justice approach that highlights repair and support for social and health injustices at the individual and collective level as well as at the material and symbolic level may be taken up to ensure reproductive justice for young pregnant women.

It advances that, having come to power through military assistance in November 2017, the new ZANU–PF government instituted cosmetic political reforms to gain domestic and international legitimacy while maintaining financial networks and tentacles on public institutions. This briefing posits that, with a huge funding base, abuse of public resources and massive vote buying, materially, Zimbabwe's 2018 elections were heavily slanted in favour of ZANU–PF.

- Description: This article, which focuses on African noir as a variety of neo-noir literature, begins by outlining the intertextual and intercultural relationships between classic noir and African noir. Thereafter, the postcolonial, postmodernist and transnational elements of African noir are described utilizing Mũkoma wa Ngũgĩ’s novel Black Star Nairobi (2013) and Leye Adenle’s When Trouble Sleeps (2018) as exemplars. Arguing that African noir draws on various genres and discourses, the article demonstrates how issues of socio-political justice, ontological and existential dilemmas, aesthetic concerns and the epistemological quest are rendered as ambiguous and murky. Based on a close reading of Black Star Nairobi and When Trouble Sleeps, the article concludes that the predominant chiaroscuro effect of African noir is not so much a ‘dark’ sensibility as one of abstruseness and poignant Afro-pessimism.

The porphyrins and conjugates were used for photodynamic antimicrobial chemotherapy (PACT) against Staphylococcus aureus. PACT uses singlet oxygen for antimicrobial activity. Complex 3 and its conjugates had higher singlet oxygen quantum yields and higher log reduction when compared with the rest of the porphyrins and corresponding conjugates. These high log reductions for 3 and its conjugate were attributed to the presence of sulfur groups whereby there was more interaction with the bacterial membrane.
