- Description: The synthesis and characterization of series of P(V) and Ga(III) A3 triarylcorrole complexes with 4-methylthiophenyl (2a, 3a), thien-3-yl (2b, 3b) and thien-2-yl (2c, 3c) meso-groups are reported along with the physicochemical and photodynamic activity properties of the dyes and their gold nanoparticle (AuNP) conjugates. The Ga(III) corrole series have lower fluorescence quantum yields and higher singlet oxygen quantum yields than the analogous P(V) complexes. Upon conjugation to AuNPs, the fluorescence quantum yields of the P(V) and Ga(III) corroles decrease, while the singlet oxygen quantum yields increase due to an external heavy atom effect. The P(V) and Ga(III) corroles exhibit relatively low in vitro dark cytotoxicity, which was further enhanced upon conjugation to AuNPs. The P(V) complexes and their AuNP conjugates display more favorable PDT activity properties upon illumination with a Thorlabs 625 nm light-emitting diode (288 J cm−2) with phototoxicity indices > 18.5 and 20.8, respectively, for the meso-thienyl-substituted 2b-AuNP and 2c-AuNP conjugates. Optical spectroscopy analyses demonstrate that this can be attributed to there being significantly less aggregation due to the presence of two trans-hydroxy axial ligands.

- 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: Rosa rubiginosa L. is a category 1b invasive plant species in South Africa and must be controlled according to NEM:BA. However, R. rubiginosa has the potential to provide economic benefit in South Africa due to the expanding market for the shrubs fruit, rosehips. The shrub is not permitted to be cultivated in South Africa due to legislation, limiting the economic potential as the rosehips are only able to be collected from wild R. rubiginosa shrubs. In order to expand the rosehip market in South Africa a downgrade or removal of R. rubiginosa from the invasive species list would be required, as wild harvest is limited. This study aims to assess the benefits and cost associated with R. rubiginosa in order to determine whether the legislation should be altered allowing for the cultivation of the shrub in South Africa. Due to the limited literature surrounding R. rubiginosa three different questionnaires and a case study were used in order to assess the benefits and negatives associated with the shrub. Experts in the field of invasion biology were surveyed to bridge the gap in the R. rubiginosa literature. Landowners, where the shrub is abundant, were surveyed to determine the negative impacts of R. rubiginosa. Rosehip companies were surveyed in order to determine the current size and potential of the R. rubiginosa (rosehip) market. The case study looked at how a rosehip company would benefit if R. rubiginosa was allowed to be cultivated in South Africa. The study found R. rubiginosa to have great economic potential and market growth, with very little negative economic impact. The case study showed that one rosehip company would grow from 1500 tons of raw rosehip to 20 000 tons if cultivation was allowed, resulting in a growth in turnover from R57 million to R760 million ($1=R14.8). The findings in the study show that R. rubiginosa does not significantly affect landowners where it is abundant. Therefore, it is suggested that a change to the legislation should be considered allowing for the cultivation of R. rubiginosa should be implemented.

- Description: A substantial portion of urban green infrastructure is under private tenure in residents’ and business/corporate gardens. Therefore, the ways that urban residents manage their gardens can influence the type, quantity and quality of ecosystem services and disservices in urban areas. Plant nurseries are a major source of trees for urban residents, and so the types of trees and species that nurseries stock influence the composition of private gardens. Consequently, this study aimed to examine the roles that plant nurseries play in shaping the urban forest in South Africa. To do so, an online and direct questionnaire was used to gather data from 30 nurseries across 19 urban centres in South Africa. The main questions included species selection criteria, customer tree inquiries, best-selling tree species, attitudes towards increasing urban tree cover and diversity and whether they think climate change will affect the selection of species to stock. The results show that there is a strong preference for indigenous trees, which were also most commonly listed as best-sellers. Non-native species that were commonly sold were ones that provided provisioning services, particularly edible fruits. Drought tolerance influenced selection criteria and customer demand. Vachellia spp. and Olea europaea were commonly inquired about and most commonly listed amongst the best-sellers. Nursery owners valued the importance of increasing tree cover and diversity in urban areas, listing many perceived benefits for doing so. We conclude that there is a clear preference for indigenous tree species by customers and nursery owners, which in time could increase the proportion and cover of native species.

- 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: The paper draws attention to the profit motive in respect of survivalist entrepreneurship at a township environment in Cape Town. Survivalist entrepreneurs have received little specific focus yet they represent a significant portion of economic activities in South Africa townships. Essentially the study considers the problem of failure to grow among survivalist entrepreneurs as reported in related literature. Many survivalist entrepreneurs fail to grow beyond the survivalist phase and there is no consensus on the underlying cause for such a phenomenon. With the Covid-19 pandemic, there is an expectation that survivalist entrepreneurs are likely to multiply owing to the collapse of many small businesses as well as the loss of employment arising from the pandemic. Two specific objective were formulated for the study: (1) to inquire into the business motives of survivalist entrepreneurs and (2) to assess the perception of the survivalist entrepreneurs on the degree to which the small business environment in supportive of motive attainment. The study adopted a quantitative research design based on the selection of respondents using a convenience sampling strategy. The evidence established from this study suggest that survivalist entrepreneurs do not pursue the profit motive significantly but they faced inhibitions presented by the economic environment in which they operate. Government and other stakeholders in the national economy are recommended to develop a suitable legal and institutional framework with strong structures to ensure the growth of survivalist entrepreneurs Keywords: Survivalist Entrepreneur, Township Entrepreneurship, Profit Motive, Small Businesses.

- Description: Land reform is an important socio-political strategy in many countries. Despite the importance of ecosystem health in attaining land reform objectives, human-nature interactions have been largely absent from contemporary land reform discussions. In this perspectives paper, we highlight why land reform programmes could benefit from considering ecosystem services in their planning processes, to better achieve their goals of socio-economic development and equity. Drawing on examples from South Africa, we argue that an ecosystem services lens can help achieve equity in land reform programmes by providing insight into how land-use legacies and the multi-functional nature of landscapes influence who benefits from land reform across space and through time.

- Description: Introduction: Advances in genomics research have raised several ethical concerns. One concern is the potential impact of genomics research on stigma experienced by people affected by a disease. Studies have found that the type of illness as well as disease causal beliefs impact on the relation between genetic attribution and stigma. This study explored the potential impact of genetic attribution of disease on stigma among Xhosa people with Rheumatic Heart Disease (RHD). Methods: Study participants were 46 Xhosa people with RHD living in the Western Cape Province of South Africa. Using video vignettes in 7 focus group discussions we explored whether and how genetic attribution may impact on disease-stigma. Vignettes introduced participants to non-genetic and genetic causal explanations and were followed-up with a series of open-ended questions eliciting their perceptions of non-genetic disease causes as well as genetic causation and its impact on internalised stigma. Results: This study found that Xhosa people with RHD have a general understanding of genetics and genetic attribution for disease. Additionally, and not withstanding their genetic knowledge, these participants hold multiple disease causal beliefs including genetic, infectious disease, psychosocial, behavioural and cultural explanations. While there was evidence of internalised stigma experiences among participants, these appeared not to be related to a genetic attribution to the disease. Discussion: The findings of this study provide clues as to why it is unlikely that a genetic conceptualisation of disease impacts internalised stigma experiences of Xhosa people. The causal explanations provided by participants reflect their cultural understandings and their context, namely, living in low-income and poverty-stricken environments. Divergence in these findings from much of the evidence from high-income countries emphasises that context matters when considering the impact of genetic attribution on stigma and caution against generalising findings from one part of the globe to another.

- Description: Introduction: Advances in genomics research have raised several ethical concerns. One concern is the potential impact of genomics research on stigma experienced by people affected by a disease. Studies have found that the type of illness as well as disease causal beliefs impact on the relation between genetic attribution and stigma. This study explored the potential impact of genetic attribution of disease on stigma among Xhosa people with Rheumatic Heart Disease (RHD). Methods: Study participants were 46 Xhosa people with RHD living in the Western Cape Province of South Africa. Using video vignettes in 7 focus group discussions we explored whether and how genetic attribution may impact on disease-stigma. Vignettes introduced participants to non-genetic and genetic causal explanations and were followed-up with a series of open-ended questions eliciting their perceptions of non-genetic disease causes as well as genetic causation and its impact on internalised stigma. Results: This study found that Xhosa people with RHD have a general understanding of genetics and genetic attribution for disease. Additionally, and not withstanding their genetic knowledge, these participants hold multiple disease causal beliefs including genetic, infectious disease, psychosocial, behavioural and cultural explanations. While there was evidence of internalised stigma experiences among participants, these appeared not to be related to a genetic attribution to the disease. Discussion: The findings of this study provide clues as to why it is unlikely that a genetic conceptualisation of disease impacts internalised stigma experiences of Xhosa people. The causal explanations provided by participants reflect their cultural understandings and their context, namely, living in low-income and poverty-stricken environments. Divergence in these findings from much of the evidence from high-income countries emphasises that context matters when considering the impact of genetic attribution on stigma and caution against generalising findings from one part of the globe to another.

- Description: It has been documented that the continual release of high numbers of biological control (biocontrol) agents for weeds increases the likelihood of agent establishment and has been shown to reduce the time between the first release and subsequent control of the target weed. Here we review the mass-rearing activities for weed biocontrol agents in South Africa between 2011 and 2020. Some 4.7 million individual insects from 40 species of biocontrol agent have been released on 31 weed species at over 2000 sites throughout South Africa during the last decade. These insects were produced at mass-rearing facilities at eight research institutions, five schools and 10 Non-Governmental Organizations. These mass-rearing activities have created employment for 41 fulltime, fixed contract staff, of which 11 are people living with physical disabilities. To improve the uptake of mass-rearing through community engagement, appropriate protocols are required to ensure that agents are produced in high numbers to suppress invasive alien plant populations in South Africa.

- Description: In this article, we examine the operation of shame in the alcohol use habits of pregnant women and the responses of their families and associated institutions. Using a narrative–discursive approach, we interviewed 13 women, living in a low-resource setting in South Africa, who had consumed alcohol while pregnant. Narratives showed how both the act of drinking and “inappropriately” timed pregnancy (early and out of wedlock) were judged to be unacceptable. Women who engaged in these activities were positioned as bad mothers or promiscuous. Their actions were seen as resulting in the suffering of others—the future child, the family, and even the community. These narratives were underpinned by cultural and religious discourses. Women managed the shame accruing to them through avoidance and concealment; families instructed women to self-exclude or distanced themselves from the women’s behavior; and institutions subtly or overtly excluded women. The shaming of these women, and the mechanisms by which such shame was managed, did little to decrease drinking or to increase maternal health and welfare. Overall, this article demonstrates how the shame of drinking alcohol during pregnancy produces avoidance behavior, concealment, and exclusion, which are not constructive in terms of maternal health and well-being. The implications for a feminist narrative approach to drinking during pregnancy are outlined: moving beyond a focus on individual behavior change to locating personal stories within the meta-narratives and social discourses that shape pregnant women’s lives.

- Description: Activists and academics have clamoured for the decolonisation of knowledge, including law. But, unfortunately hardly anyone has put forth strategies for how faculties should decolonise the law. A number of jurists have underscored the necessity to draw on customary laws and traditional values. Still, the #RhodesMustFall movement has, for the most part, been loud on the outcomes, but quiet on the methodologies. Joining the conversation on the decolonisation of epistemologies, this article contributes to the ongoing efforts to sanitise the law by proposing to revive African oral storytelling cultures as a way to analyse the questions of law facing society. To live up to this task, this article adopts decolonial theory and, through stylised examples, illustrates how lawyers and social scientists in Africa can utilise storytelling to contextualise, (de)construct, and comprehend those questions. This article assumes that lawyers can use African storytelling alongside the prevailing doctrinal method. That method, relaying the coloniality of law and captured by the acronym IRAC (issue(s), rules, application, and conclusion), trains students to approach conflict in society through a highly abstract and decontextualised problem-solving model. Lately, some (Western) social scientists have (re)discovered the practicality of storytelling in presenting analysis and research. However, in African oral traditions, stories worked differently from the manner in which those scientists employ them. African storytelling played a leading role, not only in conveying collective wisdom and social memory from one generation to the next, but also as a medium through which communities transmit the values that hold them together. Contribution: This article adds to the scholarship on storytelling and narratology by showing how educators can utilise stories to analyse legal questions. That rich scholarship in the humanities and the social sciences has so far not taken seriously the possibility of using stories to analyse research problems. Instead, scholars focus on storytelling mainly as a way of presenting science, not as an analytical tool. This article bridges that gap and demonstrates the analytical value of storytelling. Keywords: decolonisation of knowledge; decolonial theory; storytelling; Africa; analysis; epistemology; legal education; oral tradition.

- Description: In South Africa, stagnant economic growth and high unemployment rates have called for solutions from all key national institutions, including institutions of higher learning, to provide solutions. This call must be considered within the transformation discourse that arose in South Africa after the fall of the apartheid regime in 1994 and the need to equalize educational opportunities, reduce poverty and improve lives through education. All this underscores the need for a vibrant motivated, satisfied and dedicated workforce. To explain and understand the phenomena of job-satisfaction several theories have been suggested by Maslow, Vroom, Adams, McGregor, Herzberg, Alderfer’s and other authors, however theories on employee job satisfaction varies with time and place, the old theory needs to be either modified, or replaced with a new model. The study attempt to synthesize the theories of job satisfaction in the Higher Education Institution in Eastern Cape Province in South Africa. The study adopted a desktop that was designed primarily as a descriptive study to source literatures on motivation, job satisfaction, and theories. Theories are neither right nor wrong rather it depends on the context where it is applied. Theories need to be restructured according to the new areas of research in human psychology. The evidence established from this study suggest theories of job satisfaction have to be tested against these emerging factors of positive psychology and their impact on human behaviour at individual, group and organizational levels in other Higher Education institutions in South Africa.

- Description: There is no definitive or consensual Education for Sustainable Development (ESD) pedagogy but there is a suite of techniques which, if examined, will reveal similar features and principles. For example, in its ESD sourcebook, Unesco (2012) highlights pedagogies featuring question-orientated, analytical, critical and decisive skills, as well as relational pedagogies with features such as learner-centredness and participation. In its later Roadmap for Implementing the Global Action Programme for Education for Sustainable Development, Unesco calls for pedagogies that support the designing of ‘teaching and learning in an interactive, learner-centred way that enables exploratory, action-oriented and transformative learning’ (Unesco 2014: 12). An international collaborative group–ESD Expert-Net–highlighted the ‘active’ element of ESD arguing that ‘action’ or ‘doing’ elements of learning have traditionally been neglected, and that if ESD practice is to address local and global challenges ‘a strong action component’ is needed (Hoffmann and Rajeswari nd: 9). The notion of ‘active learning’has been of central interest in the Fundisa for Change project. This chapter describes its trajectory of development and use in South African ESD by outlining core features and principles for active learning. This is with a view to positioning the further chapters in this section of the book in relation to national and international research that has influenced the approach of Fundisa for Change. The chapter also serves to inform international interests in active learning.

For example, in its ESD sourcebook, Unesco (2012) highlights pedagogies featuring question-orientated, analytical, critical and decisive skills, as well as relational pedagogies with features such as learner-centredness and participation. In its later Roadmap for Implementing the Global Action Programme for Education for Sustainable Development, Unesco calls for pedagogies that support the designing of ‘teaching and learning in an interactive, learner-centred way that enables exploratory, action-oriented and transformative learning’ (Unesco 2014: 12). An international collaborative group–ESD Expert-Net–highlighted the ‘active’ element of ESD arguing that ‘action’ or ‘doing’ elements of learning have traditionally been neglected, and that if ESD practice is to address local and global challenges ‘a strong action component’ is needed (Hoffmann and Rajeswari nd: 9). The notion of ‘active learning’has been of central interest in the Fundisa for Change project. This chapter describes its trajectory of development and use in South African ESD by outlining core features and principles for active learning. This is with a view to positioning the further chapters in this section of the book in relation to national and international research that has influenced the approach of Fundisa for Change. The chapter also serves to inform international interests in active learning.

- Description: The synthesis and characterization of meso-tetra(thien-2-yl)chlorin (1) and meso-tetra(5-bromothien-2-yl)chlorin (2) is reported. These dyes have red-shifted absorption maxima compared to those of the analogous meso-tetraphenylchlorin (3). 1 and 2 have Q bands at 660 and 664 nm, respectively, singlet oxygen quantum yields of 0.60 and 0.64 and exhibit good photostability. The triplet states were found to have lifetimes of 8.6 μs in N2 purged DMF. Time-dependent cellular uptake of chlorins reached a maximum in MCF-7 cancer cells after 12 h. Upon irradiation with a Thorlabs M660L3 LED (280 mW cm−2), 2 exhibited better photocytotoxicity with an IC50 value of 2.7 μM against MCF-7 cells. The 2ʹ,7ʹ-dichlorodihydrofluorescein diacetate (DCFDA) assay provided evidence for intracellular generation of reactive oxygen species. Photodynamic inactivation of bacteria by the chlorins was also studied. 2 exhibits better activity with log reduction values of 7.42 and 8.34 towards Staphylococcus aureus and Escherichia coli, respectively, under illumination for 60 min at 660 nm with a Thorlabs M660L3 LED (280 mW cm−2). These results demonstrate that 2 is a promising candidate for future in vivo experiments and merits further in-depth investigation.

- Description: This paper examines the legacy of Ifi Amadiume's Male Daughters, Female Husbands: Gender and Sex in an African Society (1987) to African gender theorisation three decades after its publication. We argue that Amadiume's detailed ethnography of the Nnobi society provides an example of what can be achieved when African scholars centre local histories, languages, and kinship ties to provide contextualised understandings of sex and gender. In southern African societies, we assess the ways in which gender fluidity, drawing from local languages, age, seniority and lineage do not strictly fix sex to gender, thus providing possibilities for flexible gender structures that allow women to access institutions of power through the lineage as first daughters (umafungwashe) and wives, among others. We further examine the ways conservative patriarchal discourses continue distorting African cultures and traditions, thus undermining women's rights and access to social, cultural, economic and political power. We argue that current Eurocentric attempts that aim to delink sex and gender do not move us beyond the universalised binaries of gender and sex. Through revisiting local social and linguistic histories that practised gender fluidity and tolerance, we can also begin to challenge the conservative attitudes towards the LGBTQIA+ communities. Given the continued sexual and gender diversities that are being challenged daily in the African continent, it is timely that we revisit the historical meanings along with their contemporary implications for sexual citizenship and gendered power relations today.
