The sedimentology, geochemistry and diagenesis of West Rand Group sediments in the Heidelberg area, Transvaal
Published 2016“…The Jeppestown shale immediately below the Main Conglarerate has a geochemical profile that has traits of a palaeosol which has subsequently been modified by diagenesis and the percolation of ground waters. Two models are proposed for the deposition of the Hospital Hill Subgroup and the Government Subgroup by integrating the writer's detailed facies analysis approach with the work done by previous workers in other outcrop areas.…”

Expanding contraceptive options in South Africa : knowledge, attitudes, and practices surrounding the intrauterine device (IUD)
Published 2017“…Logistic regression modelling showed that, after adjusting for level of education, being from the Western Cape, older age, and having heard of emergency contraception all independently predicted awareness of the IUD method. …”

Travel and adherence to antiretroviral therapy among postpartum women living with HIV in South Africa: a cross-sectional study
Published 2020“…At the LACE study visit, data on short-term travel patterns (stayed away from home for 3 or more nights) in the past year and self-reported adherence in the past 30 days (using a validated three-item scale) were collected through structured questionnaires, and a blood specimen was tested for HIV viral load. Poisson regression models with robust standard errors were used to explore factors associated with travel (any versus none), self-reported adherence (100% versus <100%), and viral suppression (≤50 copies/mL). …”

Assessing the sustainability of seal tourism at Duiker Island, Hout Bay
Published 2021“…More women than men undertook both types of tour, though the proportion of men increased on snorkelling compared to viewing tours. Probit models revealed key behavioural and attitudinal differences between seal viewing and seal snorkelling participants with the latter being more pro-environmental. …”

Towards the Synthesis of the Unusual Monosaccharides Found in the Shigella sonnei O-Antigen and Analysis of Shigella flexneri 2a Glycoconjugate Vaccine Samples
Published 2021“…The crucial epimerization at C-5 was attempted through initial formation of the 5-ene, followed by a hydroboration/oxidation, but this led exclusively to the Drather than the L-sugar. Computer modelling and literature precedent suggested that the anomeric configuration strongly influenced the face selectivity of the hydroboration step. …”

Non-technical factors that influence the implementation of a knowledge management system in a parastatal organisation in South Africa
Published 2022“…This research contributes to the theoretical knowledge within the information systems (IS) community through developing models and theories in the extant literature that may account for the influence of organisational culture and politics in influencing the effective implementation of knowledge management systems (KMSs) in South African parastatal organisations. …”

Climate change risk to southern African native wild food plants
Published 2022“…Species distribution models were used to obtain the historical geographic range of 1190 WFP species and to make projections of range change for 2070 under both low (Representative Concentration Pathway (RCP) 2.6) and high (RCP 8.5) greenhouse gas emissions scenarios. …”

Elephant space use in relation to ephemeral surface water availability in the eastern Okavango Panhandle, Botswana
Published 2023“…The relative importance/probability of environmental variables in determining elephants' movement based on the Utilization Distribution (UD) were computed using Generalized Linear Mixed Models (GLMMs). I utilized a remote sensing spectral index, namely the Automated Water Extraction Index (AWEI) to delineate ephemeral surface water in dryland (excluding permanent waters) of the study area. …”

Plasticity and partitioning of foraging behaviour among and within sympatric Pygocelis penguin populations
Published 2025“…To test whether penguins exhibited phenotypic plasticity in foraging trip distances and duration, and to partition diving behaviours (e.g. maximum dive depth) among and within populations, I fitted a series of generalized linear mixed-effects models with species, site, breeding stage (incubation, brood and crèche) and environmental variables as covariates. …”
