- Description: For many Zimbabweans, Morgan Richard Tsvangirai (1952–2018) became the face of courage and hope during his political career. Tsvangirai was subjected to and witnessed political violence, physical abuse, brutality, emotional humiliation, unlawful detentions, and persecution. He challenged the ruling party in Zimbabwe, and his leadership gave many people hope for the future. In the context of living in a colonial era, poverty, and having to endure the brutality of the Mugabe era, he lived a meaningful life that saw him becoming a Prime Minister of Zimbabwe (2009–2013). This single-case study explores and describes Tsvangirai’s life and interprets it in terms of Frankl’s existential theory. More specifically, Tsvangirai’s life is interpreted from the perspective of Frankl’s three triads, the fundamental, meaning, and tragic triads, as well as the noetic dimension. Tsvangirai was selected through purposive sampling based on his important role in Zimbabwean politics. The primary source of data was biographical and autobiographical publications. The findings indicate that Tsvangirai shifted emphasis within the meaning triad in living a meaningful life and that he was able to use the human capacity of self-distancing/detachment and self-transcendence to find meaning in his life. This chapter sheds light on how individuals make sense of their circumstances and search for meaning and purpose in adverse conditions. It also contributes towards the development of psychobiographical research among non-WEIRD samples.

- Description: Significance Statement In the last decades, many coastal areas have observed dramatic changes in marine ecosystems, due to anthropogenic and environmental alterations. The general absence of long-term data sets in the marine environment and, more specifically, on benthic and demersal communities represents a severe issue for management and conservation. We propose to incorporate the small-scale fishers’ knowledge and science for better policy recommendations, both in terms of fisheries optimization and resource conservation. Based on two different cases of study with diverse ecosystems, we explore the combination of quantitative and qualitative tools, and participative techniques used to incorporate fishers’ local ecological knowledge. The results highlight fishers’ capacity to identify coastal and marine landscapes resources and changes, reinforcing and complementing the scientific assessment.

- Description: This chapter assesses the use of Information and Telecommunication Technologies (ICTs) for social and community learning to achieve sustainable development in rural communities in Africa. It focuses on new and emerging trends in the cooperation between the African Union and European Union (AU–EU) and links two thematic areas; namely green transitions and digital transformations. The chapter highlights low-cost and effective digital learning solutions. It is based on a literature review and cases that provide insight into potential AU–EU cooperation and the “leave no one behind” agenda. The chapter argues that in addition to digital technology transfer, innovation and investments are needed in building a learning-centred support for green transitioning and digital cooperation. Hence, we focus on transformative learning opportunities and informal Education for Sustainable Development (ESD). In response to ICTs becoming a catalyst for such a transformation, we seek insights into how constructive AU–EU cooperation and co-learning can pave ways for societal transformations, particularly in rural communities.

- Description: Futures analysis methods can help people to think constructively and systematically about the future and advance our understanding of change and uncertainty in complex social-ecological systems (SES). This is important because there is not one single predictable future but multiple ones, depending on the complex, unpredictable interplays and interactions of actors, institutions, ecological processes and other elements of the system and its dynamics. Actively developing ideas, images and/or stories about different futures can enable us to make different choices and take different actions in the present in relation to, for example, risk mitigation, adaptation, resource allocation and strategy development, which can help build more sustainable and just futures.

- Description: Malaria elimination can benefit from time and cost-efficient approaches for antimalarials such as drug repurposing. In this work, 796 DrugBank compounds were screened against 36 Plasmodium falciparum targets using QuickVina-W. Hits were selected after rescoring using GRaph Interaction Matching (GRIM) and ligand efficiency metrics: surface efficiency index (SEI), binding efficiency index (BEI) and lipophilic efficiency (LipE). They were further evaluated in Molecular dynamics (MD). Twenty-five protein–ligand complexes were finally retained from the 28,656 (36×796) dockings.

- Description: In our rapidly globalising world, "the global scholar" is a key concept for reimagining the roles of academics at the nexus of the global and the local. This book critically explores the implications of the concept for understanding postgraduate studies and supervision. It uses three conceptual lenses - "horizon", "currency" and "trajec-tory" - to organise the thirteen chapters, concluding with a reflection on the implica-tions of Covid-19 for postgraduate studies and supervision. Authors bring their perspectives on the global scholar from a variety of contexts, including South Afri-ca, Australia, the United States, the United Kingdom, Chile, Germany, Cyprus, Kenya and Israel. They explore issues around policy, research and practice, sharing a con-cern with the relation between the local and the global, and a passion for advancing postgraduate studies and supervision.

- Description: Studying social-ecological systems (SES) can be a challenging task, as explained in Chapter 2. Phenomena of interest and characteristics of SES research result from both social and ecological processes, and complicated feedback dynamics blur the distinction between cause and effect (Young et al. 2006). Furthermore, multiple causal processes may be operating simultaneously, outcomes are strongly influenced by the system’s context and it is difficult to determine system boundaries (Bodin and Prell 2011).

- Description: Cancer and malaria remain relevant pathologies in modern medicinal chemistry endeavours. This is compounded by the threat of development of resistance to existing clinical drugs in use as first-line option for treatment of these diseases. To counter this threat, strategies such as drug repurposing and hybridization are constantly adapted in contemporary drug discovery for the expansion of the drug arsenal and generation of novel chemotypes with potential to avert or delay resistance. In the present study, a polymer precursor scaffold, 1,3-benzoxazine, has been repurposed by incorporation of an organometallic ferrocene unit to produce a novel class of compounds showing in vitro biological activity against breast cancer, malaria and trypanosomiasis.

- Description: Considerable research has been devoted to understanding and promoting parent-child sexual socialisation. Less attention has been paid to experiences of sibling interactions concerning sex. Drawing on discursive psychology, this study explores how women report interacting about sex and reproduction in their sisterly relationships. Ten in-depth interviews were conducted, using Free Association Narrative Interview technique, with five Black isiXhosa-speaking, middle-aged and working class women in South Africa.

- Description: With an intention of identifying chalcone derivatives exhibiting anti-protozoal activity, a cohort of relatively unexplored arylpyrrole-based chalcone derivatives were synthesized in moderate to good yields. The resultant compounds were evaluated in vitro for their potential activity against a cultured Trypanosoma brucei brucei 427 strain. Several compounds displayed mostly modest in vitro anti-trypanosomal activity with compounds 10e and 10h emerging as active candidates with IC50 values of 4.09 and 5.11 µM, respectively.

- Description: With an intention of identifying chalcone derivatives exhibiting anti-protozoal activity, a cohort of relatively unexplored arylpyrrole-based chalcone derivatives were synthesized in moderate to good yields. The resultant compounds were evaluated in vitro for their potential activity against a cultured Trypanosoma brucei brucei 427 strain. Several compounds displayed mostly modest in vitro anti-trypanosomal activity with compounds 10e and 10h emerging as active candidates with IC50 values of 4.09 and 5.11 µM, respectively. More importantly, a concomitant assessment of their activity against a human cervix adenocarcinoma (HeLa) cell line revealed that these compounds are non-toxic.

- Description: Naidu argues that transnational crime wreaks havoc on global, national and personal levels in the postcolonial crime novels Devil’s Peak (2007) by South African author Deon Meyer and Night Prayers (2016) by Colombian author Santiago Gamboa. As postcolonial crime novels, they critique sociopolitical instability and corruption harking back to colonial times. Using mobility studies, Naidu interrogates the novels’ rendering of complex relations between the local and the global, and the past and the present. Despite stylistic and generic differences, both novels engage with the pervasive, transnational nature of criminal syndicates and current crimes which are a result of turbulent and unjust histories. Naidu examines the mobility of hapless victims, postcolonial anti-detectives and subversive heroines and comments on the ironic hope afforded by such figures.

- 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.

- Description: Faced with environmental degradation, governments worldwide are developing policies to safeguard ecosystem services (ES). Many ES models exist to support these policies, but they are generally poorly validated, especially at large scales, which undermines their credibility. To address this gap, we describe a study of multiple models of five ES, which we validate at an unprecedented scale against 1675 data points across sub-Saharan Africa.

- Description: Black Bass, a collective name for members of the centrarchid genus Micropterus, are native to North America, but have been introduced globally to enhance recreational angling. This study assessed the distribution of Micropterus salmoides, M. dolomieu and M. punctulatus in South Africa using both formal (survey-based) and informal (tournament data and social media) information sources. Analysis of the distribution data showed habitat bias between the data sources. Survey data from formal information sources were dominated by locality records in riverine environments while those derived from informal information sources focused more on lacustrine habitats. Presence data were used to develop niche models to identify suitable areas for their establishment. The predicted distribution range of M. salmoides revealed a broad suitability over most of South Africa, however, the Cape Fold Ecoregion and all coastal regions were most suitable for the establishment for both M. dolomieu and M. punctulatus. Flow accumulation and precipitation of coldest quarter were the most important environmental variables associated with the presence of all Black Bass species in South Africa. In addition, anthropogenic disturbance such as agricultural activities were associated with the presence of both Smallmouth Bass and Spotted Bass. An extensive area-based invasion debt was observed for all Micropterus spp. The potential for further spread of Black Bass in South Africa is of ecological concern because of their impact on native biota.

- Description: This paper examines the way in which blockchain technology can be used to improve the verification of integrity of evidence in digital forensics. Some background into digital forensic practices and blockchain technology are discussed to provide necessary context. A particular scalable method of verifying point-in-time existence of a piece of digital evidence, using the OpenTimestamps (OTS) service, is described, and tests are carried out to independently validate the claims made by the service. The results demonstrate that the OTS service is highly reliable with a zero false positive and false negative error rate for timestamp attestations, but that it is not suitable for timesensitive timestamping due to the variance of the accuracy of timestamps induced by block confirmation times in the Bitcoin blockchain.

- Description: This book brings the diverse contributions offered in the different sections of this book together into a pathway for new policy development research, new forms of critical skills research and ongoing engagement with education and training system development. The chapter first provides a meta-reflection on the different types of green skills research that are needed to, in combination, make a stronger impact on the national system of skills research and planning. Secondly, the chapter makes a strong argument for aligning green skills research to the Sustainable Development Goals, and their critical and contextual articulation at national level, with emphasis on working with the cross-cutting Sustainable Development Goal (SDG) 4, Target 4.7 that motivates for governments to include a focus on education and sustainable development across the lifelong learning system in order to enable and support learning and skills for enabling the other SDGs to be realised in practice. Lastly, the chapter considers the shift in the way that work is considered when political economy meets political ecology, and we argue that work transforms towards not only a productive focus, or a social focus, but also an ontologically grounded regenerative focus, much needed at the start of the twenty-first century.
