Current situation and future prognosis of health, safety and environment risk assessment of nanomaterials in South Africa
No full textThe commercialisation and everyday use of nanomaterials and nanomaterial-enabled products (NEPs) is rising year-on-year. Responsible development of nanotechnology includes understanding their potential implications on health, safety, and the environment (HSE). The health risk assessment of nanomaterials has therefore become one of the major activities of international agencies including the Organisation for Economic Co-operation and Development and the Environmental Protection Agency for protection of human health and the environment. Nationally, with the foresight and the leadership of the Department of Science and Innovation, a HSE programme was initiated to establish the necessary infrastructure to conduct the tests in the hazard identification and exposure assessment that are needed in the risk assessment of nanomaterials synthesised as well as NEPs available in South Africa. Here we present the advances that have been made in elucidating the different facets that are required when undertaking risk assessments of nanomaterials, i.e. physicochemical characterisation, hazard identification, exposure assessment and effects assessment. These facets are increasingly being considered throughout the nanomaterials present in the life cycles of NEPs. South Africa's research contribution to an international understanding of HSE risks of nanomaterials is highlighted and the future direction to generate the necessary information for effective risk communication and management is provided. This will assist in ensuring safer innovation of nanotechnology in South Africa and support the export of locally manufactured nanomaterials as per international requirements.Significance:
Significant contributions of South Africa to the nanomaterial HSE knowledge base are highlighted.
Development of standardised testing methodologies in nanomaterial HSE and protection of human and ecological health through risk assessment of nanomaterials are discussed.
This paper contributes to ensuring safer innovation of nanotechnology in South Africa
Defining the Fourth Industrial Revolution. Comments on Moll (S Afr J Sci. 2023;119(1/2), Art. #12916)
No full textMoll (S Afr J Sci. 2023;119(1/2), Art. #12916) argues that we are not currently living in the Fourth Industrial Age (4IR). In this response to Moll, I contest that Moll’s argument does not correctly reflect the understanding or definition of the 4IR as presented in the pivotal texts of the leading global and South African 4IR advocates. I believe that, had Moll focused on the definition of the 4IR presented initially by Schwab, that is, around the fusion of technologies across the digital, physical and biological worlds, he could have come to a different conclusion about the Fourth Industrial Revolution
Legislative Oversight and Executive Accountability in South Africa
No full textA glance at political theory reveals a preoccupation with the corrosive nature of power, in particular with how to ensure that the governors are sufficiently accountable to the governed. Legislative oversight is a constitutional requirement in the South African system of government. However, poor performance, maladministration and a lack of accountability in various government institutions have continued to be a major challenge. In recent years the implementation of legislative oversight has proven to be a challenge, with findings of abuse of state power revealed by reports from the Office of the Public Protector as well as corruption scandals in procurement processes. This study examines the role of parliament in holding the executive accountable in line with the constitutional values of transparency, accountability and responsiveness. Apart from delineating the reach of parliament's powers and functions, the main thrust of the study, given the existing vicissitudes in our constitutional edifice, including the failure of parliament to hold the executive accountable, is on how to strengthen the institution of parliament in its oversight role.
Other Effective Area-Based Conservation Measures, Biodiversity Stewardship and Statutory Intervention – A South African Perspective
No full textArea-based approaches are a central component of global efforts to conserve biodiversity. While the focus of many countries has been mainly on protected areas, other effective area-based conservation measures (OECMS) have been accorded global recognition in the past decade as a vital complementary approach to protected areas. This recognition has been reemphasised in the Kunming-Montreal Global Biodiversity Framework adopted by parties to the Convention on Biological Diversity in December 2022, with its Target 3 ratchetting up area-based coverage targets to 30 per cent by 2030. A growing focus and reliance on OECMs to contribute towards achieving this target is anticipated. The international community has in the past few years introduced some guidance to identify, secure, manage, monitor and verify the anticipated long-term biodiversity conservation outcomes of OECMs. Some commentators have argued for domestic legal intervention to complement this general international guidance. The South African Government has recognised the potential contribution of OECMs towards the achievement of domestic and global area-based biodiversity targets in its National Protected Areas Expansion Strategy (2018) but has alluded to the need for legal intervention to ensure that they achieve positive and sustained long-term outcomes for the in situ conservation of biodiversity. Some domestic commentators have highlighted the strong link between biodiversity stewardship (particularly conservation areas) and OECMs, advocating that these conservation areas should form the priority focus of domestic efforts to identify OECMs. This article scopes this potential link and specifically considers whether the current domestic legal and policy framework applicable to these conservation areas is sufficiently robust to ensure that only appropriate areas are identified as OECMs and that once recognised, they are governed and effectively managed in the long term. It highlights several frailties of the existing framework and drawing from anticipated legal reform in the Western Cape relating to biodiversity stewardship, it proposes a possible model for future national legislation regulating OECMs
Strengthening the biokinetics workforce for improved services: A human resources for health review from 2000 to 2020
Full text linkBackground: Biokinetics is a South African (SA) health profession within the private health care sector. Biokineticists register with the Health Professions Council of SA (HPCSA).
Objectives: To describe the demographic trends of HPCSA registered biokineticists from 2000 to 2020 to understand the supply and status of human resources for health within the profession.
Methods: The following data were collected and analysed: i) health personnel category, ii) geographical location, iii) age, iv) sex, and v) population category.
Results: The number of HPCSA registered biokineticists grew from 136 in 2000, to 1831 in January 2020 (67.8% women, 32.2% men). There was a sharp decline in numbers after the age of 45 years. The Western Cape (5.8) and Gauteng (5.1) provinces had the most biokineticists per 100 000 of the population, whilst smaller provinces like Kwazulu-Natal (1.6), Mpumalanga (1.6), North-West (1.6) and Limpopo (0.9) lagged. The demographic profile of registered Biokineticists changed steadily from 2000 to 2020. Registered biokineticists classified as White decreased from 91.6% to 80.4%, whilst substantial increases were observed among Black (5.0% to 8.3%), Coloured (0.02% to 5.3%) and Indian/Asian (0.02% to 6.0%) biokineticists. Thirteen tertiary institutions offered Biokinetics programmes in 2022. Seven offered the 3+1-year (Honours) programme and six have migrated to a 4-year professional degree.
Conclusion: The profession is well established, growing, and dominated by women. The demographic profile has transformed steadily; however, the need to transform the profession remains strong. Strengthening investments aimed at the employment of biokineticists in the public health sector may serve as a key turning point for healthcare workforce planning.
Religious metaphors and the crisis of faith in Wole Soyinka’s poetry
No full textMost commentaries on Wole Soyinka’s works across genres engage with his constant invocation of cultural tropes, most of which revolve around Ogun, his self-proclaimed muse. In this article, I highlight the centrality of religious myths and metaphors in a selection of Soyinka’s poems, namely, “Idanre” in Idanre and Other Poems (1967), Ogun Abibman (1976), “Joseph”, one of the “Four Archetypes” poems in A Shuttle in the Crypt (1972), “Mandela’s Earth” in Mandela’s Earth and Other Poems (1989), and selected poems under the sections “The Sign of the Zealot” and “Elegies” in Samarkand and Other Markets I Have Known (2002). While identifying the limitations of the poet’s Ogun trope, I dissect the centrality of faith issues in Soyinka’s poetry into two slants. The first, which is seen as encompassing his widely explored Ogun trope, is his use of religious metaphors to intervene on the dystopias in his postcolonial space. The second is his concern with the crisis of faith, a menace that has continued to threaten global peace. After drawing copious examples of religious tropes from Soyinka’s selected poems, I focus on the attention given by the poet to crisis in faith relationships. The copious examples of Soyinka’s use of religious metaphors lead to the conclusion, at the end of the paper, that access to Soyinka’s poetry is best achieved by paying attention to his religious metaphors. I also identify Soyinka’s antidote for the crisis of faith which lies in his prescription of tolerance and respect for humanist ideals
Regulating scientific and technological uncertainty: The precautionary principle in the context of human genomics and AI
No full textConsidered in isolation, the ethical and societal challenges posed by genomics and artificial intelligence (AI) are profound and include issues relating to autonomy, privacy, equality, bias, discrimination, and the abuse of power, amongst others. When these two technologies are combined, the ethical, legal and societal issues increase substantially, become much more complex, and can be scaled enormously, which increases the impact. Adding to these complexities, both genomics and AI-enabled technologies are rife with scientific and technological uncertainties, which makes the regulation of these technologies not only challenging in itself, but also creates legal uncertainties. In science, the precautionary principle has been used globally to govern uncertainty, with the specific aim to prevent irreversible harm to human beings. The regulation of uncertainties in AI-enabled technologies is based on risk as set out in the AI Regulation that was recently proposed by the European Commission. However, when genomics and artificial intelligence are combined, not only do uncertainties double, but the current regulation of such uncertainties towards the safe use thereof for humans seems contradictory, considering the different approaches followed by science and technology in this regard. In this article, I explore the regulation of both scientific and technological uncertainties and argue that the application of the precautionary principle in the context of human genomics and AI seems to be the most effective way to regulate the uncertainties brought about by the combination of these two technologies.
Significance:
The significance of this article rests in the criteria framework proposed for the determination of the applicability of the precautionary principle and lessons learnt from the European Union’s attempt to regulate artificial intelligence
The Fourth Industrial Revolution: Conceptual paradox or catalyst for achieving the Sustainable Development Goals?
No full textThe topic of the Fourth Industrial Revolution (4IR) became significant in South Africa from 2017, through advocacy, amongst others, by the University of Johannesburg and subsequently through the appointment of the Presidential Commission on 4IR. Preceding industrial revolutions each focused on a single technology; 4IR, however, speaks to a confluence of technologies and a synergy of computing, data, and communications technology, with artificial intelligence rapidly redefining the world of work. Conceptual and geopolitical challenges and potential negative societal implications notwithstanding, we argue that the 4IR paradigm shift is critical to South Africa and to realising the Sustainable Development Goals
AquaSens: exploring the use of 16S rRNA next-generation sequencing to determine bacterial composition of various water matrices
No full textAccess to clean water, one of the United Nation’s Sustainable Development Goals, is challenged by an increase in the presence of emerging microbial and other contaminants due to urbanization, among other factors. Traditionally, the presence of indicator microorganisms is determined using culturing methods. However, these classical methods cannot be used to determine the identities of ‘unknown’ bacteria and is limited to isolating the culturable state of microorganisms. Thus with culturing, the identities of many bacteria, particularly novel or non-culturable, may remain unknown. The use of a DNA-based method, 16S rRNA next-generation sequencing (NGS), can assist with determining the identities of bacterial populations in a water sample. The objective of this 16S rRNA NGS study was to investigate the bacterial community composition and diversity in a range of water sources. Water samples comprising of potable, surface, ground, marine, aquaculture, rain, wetland and swimming bath water matrices were subjected to 16S rRNA NGS using the Illumina 16S rRNA Metagenomics analysis pipeline. Operational taxonomic units were analysed and the identities of bacterial genera determined. In this study, genera of Acinetobacter, Mycobacterium, Pseudomonas, Legionella, Burkholderia, Yersinia, Staphylococcus and Vibrio were spread across the water matrices. Alpha (within sample) and beta (between samples) diversities for each bacterial community within the tested samples were also determined
