The Impact of Digital Leadership on Digital Maturity: A South African Case Study
(University of the Witwatersrand, Johannesburg, 2024) Jaffer, Aasma; Sethibe, Tebogo
In the rapidly evolving landscape of digital transformation, the role of digital leadership in driving organizational maturity has become increasingly crucial. This study investigates the impact of digital leadership on digital maturity within the South African fintech sector, aiming to provide insights into the mechanisms through which leadership practices influence digital maturity at a factor level. This was broken down into two key areas: identifying the most critical indicators of digital maturity and investigating the impact of digital leadership on five factors of digital maturity based on the digital maturity model used. Drawing upon a conceptual framework rooted in the literature on digital leadership and digital maturity, the study utilises an established digital maturity instrument, the Unified Digital Maturity Model by Armstrong & Lee (2021). The research employed a quantitative approach, utilizing a sample of 150 employees from various fintech companies in South Africa. Data was collected through a structured survey instrument, and statistical analysis, including regression analysis, was conducted to examine the relationship between digital leadership behaviours and organizational digital maturity levels. The findings reveal significant positive correlations between digital leadership and all five factors of digital maturity studied, namely Customer Orientation & Engagement, Digital Product Innovation, Workforce Enablement & Performance, Core Processes Digitisation and New Value Streams & Business Models. The study identifies the top three most critical digital maturity constructs as Organisational Culture, Workforce Enablement & Performance, Customer Orientation and at indicator level, found eight critical variables. These results underscore the importance of cultivating digital leadership capabilities to foster high digital maturity and in turn, streamline digital transformation in the South African fintech context. The study concludes by highlighting the imperative for organizations to prioritize investments in digital leadership development as a strategic imperative for navigating the digital landscape effectively.

Exploring temporal changes in the malting barley seed microbiome with meta-omics to understand nitrogen content effects
(University of the Witwatersrand, Johannesburg, 2024-10) Tshisekedi, Kalonji Abondance; De Maayer, Pieter; Botes, Angela
Barley (Hordeum vulgare L.) is a critical cereal crop, particularly in beer production, where it plays a significant role in the economy, especially in South Africa. Despite its importance, the barley seed microbiome, which affects seed storage and quality, is not well understood. This research addresses two key questions: (1) how microbial composition and function evolve during storage and (2) how the inherent nitrogen content of the grain affects these dynamics. Using metagenomic and metaproteomic approaches, eight barley samples from the Kadie cultivar, stored for various durations (harvest, three, six, and nine months) with high and low nitrogen content, were analysed. Metagenomic sequencing revealed a predominance of bacterial sequences and minimal fungal presence, with storage time having a greater impact on microbial diversity than nitrogen content. However, specific bacterial genera such as Erwinia, Pantoea, Pseudomonas, and Stenotrophomonas showed nitrogen-dependent prevalence. Metagenome-assembled genomes (MAGs) were reconstructed, representing 26 bacterial genera, with minimal shared orthologues, highlighting taxonomic diversity. Functional analysis identified key metabolic pathways and carbohydrate-active enzymes (CAZymes) essential for microbial adaptation during storage. Metaproteomic analysis further showed the active expression of proteins related to nutrient transport and stress response, indicating functional changes over storage time. Overall, this research enhances the understanding of the barley seed microbiome, providing valuable insights into storage practices that could improve brewing quality and agricultural sustainability.

Digital innovation and disruptive potential by FinTech companies in South Africa
(University of the Witwatersrand, Johannesburg, 2024) Freund, Amelia; Omotoso, Pelayo
FinTech companies are seen bring innovation to the financial services industry that provide an enhanced customer experience and improves financial inclusion. A contradiction exists between academic and business literature around the potential impact of the FinTech revolution on the industry and banks as incumbents in the financial services industry. This paper aims to clarify this by assessing the degree of potential disruption that domestic new-entrant FinTech companies in the payments sub-sector have on incumbent banks in South Africa, so that both parties could make informed decisions that benefit the industry and its customers. This qualitative study examines the drivers of potential disruption and the decisions made by both FinTech new-entrants and banks to develop a synthesis for a likely future scenario relating to potential changes in dominance within the financial services industry. It further analyses the advantages and challenges of each party in the context of a potential partnership and examines management views to determine alignment with the drivers of disruption. This cross-sectional study employs document analysis to examine 42 new-entrant FinTech companies in the payments sub-sector and 5 banks, in addition to the thematic analysis of semi-structured interviews 15 semi- structured interviews conducted. It was found that domestic new-entrant FinTech companies are not likely to disrupt banks (to the point where FinTech companies become more dominant) in the payments sub-sector in South Africa due to the influence of banks in the industry and the proactive response from banks to potential disruptions. Banks should, however, take notice of developments and more seriously consider solutions in the cross-border remittance and blockchain spaces. Managers may have slight differences in their opinions, but overall, they are aligned with the factors driving disruption and the influence of FinTech companies on the financial services sector. This alignment enables them to make strategic decisions effectively without significant misconceptions. The study discovered a potential mutually beneficial link between FinTech companies and banks that indicate partnerships between them might enhance their services to customers and enhance their overall competitive standing in the market

The implications of mandible morphology and dental structure on the feeding ecology and predatory behaviour in Hyaenidae (hyenas) using geometric morphometric analyses
(University of the Witwatersrand, Johannesburg, 2024-03) Naidoo, Riyanta; Iqbal, Safiyyah
Hyenas are often overlooked as being successful predators due to their scavenging behaviour. However, their morphological adaptations allow them to succeed in bone-cracking behaviour, an act that most carnivores are unable to achieve. Craniodental morphology influences carnivore performance, therefore understanding the functional morphology of carnivore mandibles would allow for the justification of Hyaenidae behaviour. This study investigates the morphological differences between the Hyaenidae mandible and large carnivore mandibles in Africa, as well as the differences in mandible morphology within the Hyaenidae family. This study uses a two-dimensional landmark-based geometric morphometric methodology to analyse morphological features on the carnivore mandibles and dentition to determine the morphological clusters linking the carnivore species, determine how the mandible morphology accommodates biomechanical needs, and to determine the implications that mandible morphology and dentition has on feeding ecology. The results of this study indicated that the sizes (PC1) of the carnivore mandibles were clustered according to their respective families (i.e. Hyaenidae, Canidae, and Felidae), however the shape (PC2) of the mandibles differed according to diet. The mandible morphology of the hypercarnivorous Hyaenidae displayed evident adaptations to osteophagy behaviour, including a thickened corpus, a large masseteric fossa, an anteriorly-displaced coronoid, and robust and blunt-like canines. The Proteles cristata, however, displayed mandibular adaptations to a hypocarnivorous diet. Ultimately, it was found that an increased resistance to bending forces and an increased area for muscle attachment on the mandible, directly relates to an increase in the Hyaenidae bite force, improving their feeding and hunting success.

Exploring the role of social media influencers and brand ambassadors in influencing purchase intention
(University of the Witwatersrand, Johannesburg, 2024) Da Fonseca, Helen; Saini , Yvonne
This study investigates the comparative influence of social media influencers and celebrity brand ambassadors on purchase intention within the South African cosmetics industry, specifically targeting millennial and Generation Z consumers. Grounded in the Source Credibility Model, the research examines how credibility, trustworthiness, and expertise shape consumer decision-making. Social Media Influencer-Driven Purchase Intention (SIPI) and Brand Ambassador-Driven Purchase Intention (BAPI) were introduced as higher-order constructs to evaluate and compare which type of endorser has a stronger influence on overall purchase intention. A Structural Equation Modeling (SEM) methodology was used to analyse survey data collected from 130 respondents. The findings indicate that both Social Media Influencer-Driven Purchase Intention (SIPI) and Brand Ambassador-Driven Purchase Intention (BAPI) influence consumer purchase intention, with celebrity brand ambassadors exerting a more substantial effect due to their higher perceived credibility and expertise. Celebrity brand ambassadors were shown to play a pivotal role in enhancing consumer trust and confidence, making them more effective in driving purchase behaviour compared to social media influencers. These insights offer strategic guidance for marketers and brands looking to refine their influencer marketing strategies to better resonate with the evolving preferences of millennial and Generation Z consumers in the South African market.
