- Description: In 2013, Zimbabwe adopted a new constitution that declared 16 officially recognised languages. In line with the new constitutional provision that all the official languages be treated with parity, the teaching of minority languages ceased to be optional. Yet there were neither trained teachers nor educational materials to implement their teaching. In this chapter, it is examined how Ndebele L1 teachers and learners in the Tonga-speaking community of Binga negotiate their identities by learning Tonga. Ndebele L1 learners learn Tonga as the new legitimate Indigenous language offered in their schools, which brings interesting dynamics in terms of language learning challenges and attitudes. Ndebele L1 teachers must reinvent themselves to assume the instructional responsibilities in the learning of the minority language and to retain their jobs. These teachers therefore learn the languages from the community including their own learners, thereby providing an exciting case of speakers of majority language speakers learning a minority language that they also must teach. This study therefore presents an interesting case where minority language–speaking learners and majority language–speaking teachers collaboratively and reciprocally participate in the teaching of the minority language.

- Description: The devastating impact of the COVID-19 virus is well-documented. The disease was less severe among young people than in the older population. The effect on adolescents was primarily due to government measures to curb the pandemic, including lockdowns that disrupted social, education, and health services and diverted resources away from sexual and reproductive health. Young people lost or had limited access to sexual and reproductive health services and comprehensive sexuality education. They experienced the loss of financial and emotional support and parental care because of sick adults and caregivers. Young persons also lost time with friends and in developmental tasks associated with adolescence, such as exploring intimate relationships and forming identities outside the home. Government-imposed lockdowns and isolation measures revealed how being home can be problematic for young people, despite the concept of ‘home’ suggesting safety, security, and nurturance. Of particular concern were sexual and gender-based violence in the home and the increase in teenage pregnancies. In this chapter, we engage with the notion of home and how all institutions with which the adolescent interacts, especially family and school, should be a ‘home’: A place of belonging and acceptance because adolescence is a critical time for the emergence of sexual identity.

- Description: Mixed-species flocks of foraging insectivorous birds are found worldwide and have been best studied in the Neotropical region. A survey of the published literature reveals that mixed-species flocks (often termed ‘bird parties’) comprised of 2–30 species and sometimes >70 individual birds are regularly encountered in forest and woodland habitats throughout the Afrotropical region. On mainland Africa, >600 species representing 59 bird families have been reported in such flocks, and for at least 300 species foraging in such flocks may constitute an important part of their feeding activity. In Madagascar, >60 species of 19 families have been recorded in mixed-species flocks, with more than 40 species frequent participants. These foraging parties are dominated by gleaning and sallying insectivorous birds, with other feeding guilds represented by fewer species and individuals.

- Description: Terminology development and practical lexicography are crucial in language intellectualization. In South Africa, the Department of Sport, Arts and Culture, National Lexicography Units, universities, commercial publishers and other organizations have been developing terminology and publishing terminographical/lexicographical resources to facilitate the use of African languages alongside English and Afrikaans in prestigious domains. Theoretical literature in the field of lexicography (eg, Bergenholtz and Nielsen (2006); Bergenholtz and Tarp (1995; 2010); Gouws 2020) has attempted to resolve traditional distinctions between lexicography and terminology while also addressing terminological imprecisions in the relevant scholarship. Taking the cue from such scholarship, this article reflects on the methodological approaches for developing lexicographical products for specific subject fields, ie, resources that document and describe terminology from specialized academic and professional fields. Its focus is on the use of traditional methods vis-à-vis the application of electronic corpora and its technologies in the key practical tasks such as term extraction and lemmatization. The article notes that the limited availability of specialized texts in African languages hampers the development and deployment of advanced electronic corpora and its applications to improve the execution of terminological and lexicographical tasks, while also enhancing the quality of the products. The Illustrated Glossary of Southern African Architectural Terms (English–isiZulu), A Glossary of Law Terms (English–isiZulu) and the forthcoming isiZulu dictionary of linguistic terms are used for special reference.

- Description: This paper articulates the patterns and feel of graduate underemployment in Mthatha, a South African town in the Eastern Cape Province. Foregrounded on Peter Blua’s Social Exchange Theory, this study adopted a quantitative approach. A sample of 60 respondents was drawn from underemployed graduate population through a combination of stratified and random sampling techniques. Data collected from survey (questionnaire) were analysed with appropriate tools in the Statistical Package for the Social Sciences. The study found that majority of underemployed graduates are between 21 and 25 years of age, married, hold bachelor’s degrees in Social Sciences. Gender, qualification type and level of qualification have no significant influence on determining underemployed graduates’ choice of occupation as single and combined variables or factors. While only very few (5%) of the underemployed graduates are never happy at work, femaleness, older graduates, Africans, higher qualification, higher basic salary and longer years of underemployment best predict happiness at work, although not at significant level, except for basic salary. A majority of graduates (73.3%) do sometimes consider leaving their current jobs, even when there are no alternatives. This is influenced by maleness, older graduates, being Whites, higher qualification, lower basic salary and lower years of underemployment. Lack of networking was found to be the most important factor in graduate underemployment, followed by lack of experience and gender not being significant. This study recommends policy intervention by state, where there is legislation that provides for entry level jobs that may not require previous experience. Also, there should be another legislation that protects the underemployed through salary regulation and incentivising of employers that engage workers in such capacity. Keywords: Underemployment, Youth, Graduates, South Africa.

- Description: All of humankind, urban and rural, rich and poor and whether living in the Global South or the Global North rely to some degree on provisioning ecosystem services such as food, water, timber, fibre and medicinal products. However, in contrast to the Global North the contextual forces shaping many urban livelihoods in the Global South necessitate that many people access the needed provisioning services themselves by directly harvesting or collecting from the immediate, local urban and peri-urban environments, or purchasing them from those who do. Thus, the need for and local availability of provisioning services has profound implications for not only the quality of urban livelihoods, but also the urban ecology in relation to extent and use of urban green infrastructure from where the provisioning services are sourced and the species within them. This chapter summarises compelling evidence from throughout the Global South regarding the extent of use of locally sourced provisioning services by urban communities. It shows that Global South contexts prompt the use of a diverse array of resource types and hundreds of different species in specific settings, much greater than found in Global North cities.

- Description: The period since the Second World War has been marked by rapid and accelerating changes to many aspects of human society and the environment (Clark, Crutzen, and Schellnhuber 2004; Steffen et al. 2011; Steffen et al. 2015a). There is accumulating evidence and rising concern about the potential consequences these changes hold for key Earth system processes at a global scale, and human well-being and prosperity into the future (Krausmann et al. 2013; Steffen et al. 2015b). The Anthropocene, as this new era of extensive human impact on the Earth has come to be known (Crutzen 2006), manifests in a closely intertwined set of social and ecological changes. Technological advances, increasing human population, rising levels of wealth and consumption, and the institutional arrangements we have developed to govern our economies and societies interplay with one another, and drastically affect the Earth’s climate, biological diversity, fresh-water and biogeochemical flows, and levels of novel pollutants in the environment (Steffen et al. 2015a). These environmental changes, in turn, contribute to increasingly frequent and severe droughts (Dai 2013; Trenberth et al. 2014), floods (Milly et al. 2002; Nicholls 2004), heatwaves (Guo et al. 2018; Oliver et al. 2018) and the emergence of novel pathogens such as SARS-CoV-2 (Everard et al. 2020; O ’Callaghan-Gordo and Antò 2020; Schmeller, Courchamp, and Killeen 2020) that can lead to massive societal disruption and hardship, especially among the poor (Wheeler and Von Braun 2013; Barbier and Hochard 2018).

- Description: It has been suggested that tourism fisheries can raise the value of landed catch, provide alternative livelihoods for local artisanal fishers and, because recreationally caught fishes are often released, simultaneously conserve stocks. However, for fishing tourism to meet ecotourism standards, sustainable, local economic benefit is imperative. This study aimed to assess the direct economic contribution of the recreational fishery for Polydactylus quadrifilis on the Kwanza Estuary, Angola. The recreational fishery contributed significantly to economic productivity in an otherwise rural area, generating a total revenue (TR) of $236,826 per four-month fishing season.

- Description: Prevailing approaches to the structural challenges of Corporate Social Responsibility (CSR) tend to be monolithic and skewed towards CSR at the organisational level. Albeit, mirroring CSR at the organisational level with activities of practitioners at the social level can offer new reflexive approaches for identifying capabilities for and understanding thresholds of social learning. This chapter maps out how identity perspectives to CSR can offer new approaches for surfacing emergent properties inherent in the uptake of CSR institutionally and in practice. The chapter also presents an overview of the interplay be-tween structure and agency (prescribed and actual CSR practices) and its underlying in-strumental role for illuminating systemic factors which perpetuate such capabilities and thresholds. Using a morphogenetic theo-ry of change, the chapter offers a framework for approaching CSR-based corporate identity. Empirical evidence from the applied framework is thereafter presented, in the context of the agro-processing industry based on a content analysis of an-nual reports, in-depth-interview data generated from four sus-tainability managers and corporate communication officers and the practices of extension and Local Economic Development (LED) officers. The framework demonstrates that companies with a disintegrated CSR identity inherently have more capaci-ty to be change agents. Similarly, a strong corporate heritage identity is not indicative of a reciprocal link between espoused values and activity. Conversely, an enduring corporate herit-age identity may not necessarily be improvisatory for social learning. In conclusion, the chapter gives an overview of a tax-onomy of agential capabilities and associated cognitive re-sources inherent in the interaction between structural-cultural and personal emergent properties, which can initiate the posi-tioning of social learning at the forefront of organisational de-liberations.

- Description: Forensic entomotoxicology deals mainly with the analysis of the tissues of insects to identify toxicants present in their food sources. Insects feeding on human tissues can ingest all of the xenobiotic substances taken by living individuals, such as common prescription and illicit drugs. Ecotoxicology is a well-established scientific discipline from which environmental forensic entomotoxicology is derived as a relatively new branch. Entomotoxicology also addresses the effects of drugs and toxins on arthropod development, survival, morphology, and their implications for estimating postmortem intervals. The primary focus of a forensic toxicologist is the detection of toxicants from human tissue samples to help in determining the cause of death. Like nutrients, toxicants encountered by an insect may be assimilated, digested, absorbed, and either sequestered, metabolized, or excreted. Entomological samples are currently of limited quantitative value in forensic toxicology.

- Description: Here we describe an interdisciplinary and multi-country initiative to develop rapid, participatory methods to assess the vulnerability of coastal communities and facilitate adaptation to climate change in data-poor regions. The methods were applied in Madagascar as a case study. The initiative centered on an exploratory research exercise in two communities in the south-west of Madagascar, a workshop held in Antananarivo in June 2016, combined with a component on communicating ocean science and climate change to stakeholders. It utilized innovative and rapid approaches to combine global and local skills and information on adaptation and resilience building, taking cognizance of national policies, and was based on the principles of a holistic, integrated and participatory approach. This paper summarizes the activities undertaken and assesses how effective they were in achieving the project goals, as well as presenting examples of the outputs obtained.

- Description: Supporting green skills development is integral in the transition to a green economy. Green skills can be difficult to define and measure at an aggregate level because they are a socially constructed concept, intangible and are often unobservable. Further, a demand-led approach to green skills has not worked because employers are unable to effectively articulate their needs to skills delivery bodies. This advances the need for a transformative methodology that is able to provide a more nu-anced view of skills planning to support green work. Drawing on transition theorists, this chapter demonstrates that greening work transitions occur in “niches” at local levels, where nexus concerns arise around the impetus to green work. Furthermore, it is from these transformative niches that wider social changes and regime shifts are driven or emerge. Using experiences from the chemicals sector in South Africa, the chapter illus-trates the need to develop non-reductionist conceptualisations that illustrate the “regime lock-ins” as well as green skills oppor-tunities at multiple levels.

- Description: One of the functions art serves is to visually document history for generations to come. Even with the development of writing, the artists have continued to document various aspects of what they encounter in their various communities. In Nigeria with particular reference to painting, several artists have used their paintings as visual documentaries. The introduction of the camera as a tool for documenting did little to dissuade these painters from continuing this role. This paper therefore examined selected paintings of artists in Nigeria, whose works reveal historical evidences and culture of a people. Paintings cutting across the various genres such as portraits, landscapes scenes, architecture, festivals and cultural issues from pre-independence Nigeria to the present were selected for examination and analysis. The paper explores a descriptive and comparative analysis of the selected paintings vis-à-vis the various subjects they have recorded. It concludes that these paintings show significant historical evidences that can be used to reconstruct history and others aspects of the society where the need may arise. Painters in Nigeria more than other artists have been able to record history with their works because of the pictorial and compositional peculiarity of painting as an art form.

As societies grapple with the rapid and catastrophic effects of environmental degradation, anthropogenic earth system change and a long history of unsustainable development, educa-tional systems have had to attempt to comprehend meaningfully, the im-plications. Within post-apartheid South Africa, these challenges are mark-edly more complex. In a country facing fundamental national transfor-mation on every front, the environment and sustainable development discourses are raising significant new challenges for work and learning systems.

- Description: One explanation for the increasing prevalence of stunting in South Africa over the past 15 years while other development indicators have improved is that Big Food retail chains have been contributing to a low quality diet across the country, particularly in poor urban households. We thus use nationally representative longitudinal data (2008–2014) to trace 6 years of stunting’s evolution among South African children, adolescents, and young adults aged 0–19, with particular attention to how the prevalence of under-nutrition differs between urban and rural areas and how the drivers of poor nutrition vary spatially. The results of our random-effects logistic regressions on the nutritional impact of household agricultural production suggest that, conditional on household income, subsistence farming is associated with a lower probability of stunting. Even more important, although under-nutrition retains a strong spatial component, once observable differences in living standards are controlled for, the higher tendency for children in deep rural households to suffer from (severe) stunting reverses.

We explore the potential for using a combination of two methodological tools for our learning path-ways research, in order to address the central methodological question raised through the literature review of learning pathways research, which highlighted a macro-micro dualism this area of study (see Paper 3 in this Bulletin). In Paper 4, we seek to explore whether Bhaskar’s (1993) dialec-tical approach may help with addressing this methodological dualism. We do this through applying the dialectical method, to career stories research approaches, which are one of the foundational approaches used in learn-ing pathways research (see Paper 3 in this Bulletin). Our analysis in this paper therefore uses (a) the development of ‘career stories’ and (b) Criti-cal Realist analysis of these career stories, using Bhaskar’s (1993) dialecti-cal method which foregrounds both absence and emergence.

- Description: publisher version , Lignocellulosic biomass has been considered as an important and sustainable source of renewable energy. Cellulose constitutes the major component of the lignocellulosic biomass and also offers maximum recalcitrance towards its fullest utilization. The enzymatic breakdown of cellulose is achieved through cellulases. Diverse forms of microbes including fungi, bacteria, actinomycetes and yeast are known to produce cellulases that have found extensive application in various industries. Due to the current global political unrest over oil prices and the threat of global warming following combustion of fossil fuels, the paradigm of research is now focused on biofuel production from plant biomass. Conventional approaches have not been economically feasible for meeting the demands of the industry. This review provides an update regarding the status of present microbial cellulase production technologies and research with special reference to solid state fermentation and different molecular techniques such as mutagenesis, metabolic engineering and heterologous gene expression of cellulases from different microbial domains with improved catalytic and stability properties. Metagenomic and genomic studies for mining of novel cellulase genes in addition to screening of culturable strains using conventional methods have been advanced. In addition the bottlenecks associated with cellulase production and how the future research needs to be directed to provide a comprehensive technology for the production of cellulases with novel traits for application at an industrial level without economic constraints are discussed.

- Description: This edited work has gathered together contributions on how to transform universities in South Africa; as many are struggling to shift their institutional culture. In a South African context, transformation means to attempt to change higher education institutions such that they no longer reflect the values promoted by apartheid but rather reflect the values embodied in South Africa's 1996 Constitution. Institutional culture is the main subject for discussion in this book. In order to transform South Africa's universities, the contributors begin by analyzing the idea of what a university is, and relatedly, what its ideal aims are. A second theme is to understand what institutional culture is and how it functions. Moreover, transformation cannot occur without transforming the broader cultures of which they are a part. Related to this theme is a general concern about how contemporary moves towards the instrumentalization of higher education affect the ability to transform institutions. These institutions are being pushed to conform to goals that are outside the traditional idea of a university, such as concerns that universities are being 'bureaucratized' and becoming corporations, instead of a place of learning open to all. In conclusion it can be said that the contemporary South African academic community has an opportunity to recreate itself as the end of apartheid created space for engaging in transformative epistemic projects. The transformation of the tertiary sector entails a transformation of institutional cultures.

- Description: This edited work has gathered together contributions on how to transform universities in South Africa; as many are struggling to shift their institutional culture. In a South African context, transformation means to attempt to change higher education institutions such that they no longer reflect the values promoted by apartheid but rather reflect the values embodied in South Africa's 1996 Constitution. Institutional culture is the main subject for discussion in this book. In order to transform South Africa's universities, the contributors begin by analyzing the idea of what a university is, and relatedly, what its ideal aims are. A second theme is to understand what institutional culture is and how it functions. Moreover, transformation cannot occur without transforming the broader cultures of which they are a part. Related to this theme is a general concern about how contemporary moves towards the instrumentalization of higher education affect the ability to transform institutions. These institutions are being pushed to conform to goals that are outside the traditional idea of a university, such as concerns that universities are being 'bureaucratized' and becoming corporations, instead of a place of learning open to all. In conclusion it can be said that the contemporary South African academic community has an opportunity to recreate itself as the end of apartheid created space for engaging in transformative epistemic projects. The transformation of the tertiary sector entails a transformation of institutional cultures.
