Sociodemographic and lifestyle factors and the risk of metabolic syndrome in taxi drivers: A focus on street food
(Frontiers Media, 2023)In South Africa, similar to other populous countries, the taxi industry is an important form of transportation that contributes to the country’s development. As a result, minibus taxi driving is an occupation characterized ... -
Worrier state: Risk, anxiety and moral panic in South Africa
(SAGE Publications, 2023)While reading Nicky Falkof’s Worrier State: Risk, anxiety, and moral panic in South Africa, I couldn’t help but think of the video of Nina Simone being interviewed that often floats around social media where she is asked ... -
Facile synthesis of NiSe2:α-Fe2O3 thin film: physical, optical and photoelectronic properties
(Thin Solid Films, 2023)In this study, a highly scalable approach to fabricating NiSe2:α-Fe2O3 heterojunction thin film in the absence of a dehydration step or lattice parameter matching was established. The attachment of NiSe2 to α-Fe2O3 leads ... -
Digital development, inequalities & the Sustainable DevelopmentGoals: What does‘Leave No-One Behind’mean for ICT4D?
(Taylor and Francis Group, 2023)The United Nations’Sustainable Development Goals (SDGs) place greatemphasis on inequalities and pledge toleave no-one behind. For thefield of digital development, this objective presents a particularchallenge. While ... -
Redshift evolution of galaxy group X-ray properties in the SIMBA simulations
(Oxford University Press, 2023)We examine the evolution of intragroup gas rest-frame X-ray scaling relations for group-sized haloes (M500 = 1012.3–1015 M) in the SIMBA galaxy formation simulation. X-ray luminosity LX versus M500 shows increasing deviation ... -
Descriptive epidemiology of and response to the high pathogenicity avian influenza (h5n8) epidemic in South African coastal seabirds, 2018
(Wiley, 2023)High pathogenicity avian infuenza (HPAI) clade 2.3.4.4b H5N8 virus was detected in coastal seabirds in late 2017 in South Africa, following a devastating epidemic in the commercial poultry and ostrich industries. By May ... -
New constraints on primordial features from the galaxy two-point correlation function
(Physical Review, 2023)Features in the primordial power spectrum represent the imprinted signal in the density perturbations of the physics and evolution of the early Universe. A measurement of such signals will represents the need to go beyond ... -
A new technique to isolate kinematically anomalous gas in HI data cubes
(Oxford University Press, 2023)H I line observations of nearby galaxies often reveal the presence of extraplanar and/or kinematically anomalous gas that deviates from the general circular flow. In this work, we study the dependence of kinematically ... -
Global warming and psychotraumatology of natural disasters: the case of the deadly rains and floods of April 2022 in South Africa
(Annales Médico-psychologiques, revue psychiatrique, 2023)Climate change and global warming have led to an increased incidence of flooding across the world. Against the backdrop of the recent devastating floods in the Kwazulu-Natal province of South Africa, this paper explores ... -
New palladium (II) complexes from halogen substituted Schiff base ligands: Synthesis, spectroscopic, biological activity, density functional theory, and molecular docking investigations
(Inorganica Chimica Acta, 2023)Two novel palladium (II) complexes Pd(L1)2 and Pd(L2)2 derived from ON donor bidentate ligands: 2-(((2-bromo-4-chlorophenyl)imino)methyl)phenol (HL1) and 2-(((-bromo-4-methylphenyl)imino)methyl)phenol (HL2) are reported. ... -
Zinc(II) complex of (Z)-4-((4-nitrophenyl)amino)pent-3-en-2-one, a potential antimicrobial agent: synthesis, characterization, antimicrobial screening, DFT calculation and docking study
(Bulletin of the Chemical Society of Ethiopia, 2023)Herein, the synthesis and characterizations of (Z)-4-((4-nitrophenyl)amino)pent-3-en-2-one (HL) ligand and its Zn(II) complex are reported. The compounds were characterized using elemental and thermogravimetric (TGA) ... -
Chirality and octupole correlations in As-74
(Physical Review C, 2022)High-spin states in 74As were studied using the 74Ge(4He, 1p3n) reaction at beam energies of 58.6 and 62.6 MeV. Two positive- and one negative-parity bands have been identified in 74As. The two positive-parity bands ... -
Towards an emergent curriculum for climate justice adult educators/activists
(Australian Journal of Adult Learning, 2022)Ecoliteracy is essential for adult educators/activists en route to creating ecoliterate populations. Working cooperatively with other networks in the spirit of a ‘solidarity economy’, a group within the PIMA network has ... -
Bayesian jackknife tests with a small number of subsets: application to HERA 21 cm power spectrum upper limits
(Monthly Notices of the Royal Astronomical Society, 2023)We present a Bayesian jackknife test for assessing the probability that a data set contains biased subsets, and, if so, which of the subsets are likely to be biased. The test can be used to assess the presence and likely ... -
