- Description: The increase in the number of channels driven by technology trajectory over the years have led to a change in customer behaviour. Customers move around different retailer platforms during a single purchase; even so customers still expect a superior and seamless customer experience while navigating these channels. The present study built on studies conducted in countries such as China, Spain, India, United Kingdom amongst others to determine if the learnings from these countries can be applied in the South African context. This study used an interpretivist phenomenological approach and interviewed a qualitative sample of participants to gain insights on their experiences while shopping in these retailers. This study will assist Information Technology managers with prioritisation of their technology roadmaps. This study will also contribute to computer science studies because programmers will have a context of a customer’s perspective when developing omnichannel solutions. Lastly, the study can be used by governments and policy makers in developing national strategic plans relating to shared economy because the study highlights the need to omnichannel retailing in remote areas. The findings from the research were summarised into five themes customer experience, convenience, product, support, and security. The optimal South African omnichannel retail experience is one that allows the customer to seamlessly move across channels by integrating the retailing mix elements of product, place, promotion, price. To achieve this experience, retailers must integrate the customer’s profile information and ensure that the customer’s payment details are secure and are able to seamlessly login in all the retailer platforms. Contrary to the researcher’s expectations, South African customers do not expect an omnichannel support. They expect to keep online support separate from in-store support. , Thesis (MA) -- Faculty of Business and Economic Sciences, 2023

- Description: Cryptococcus neoformans is responsible for cryptococcal infections, which have become a great concern particularly in immunocompromised patients. This pulmonary disease causes damage to lung tissue and is presumed to be responsible for approximately 650,000 deaths annually. There is a major need for novel antimicrobial agents to avoid the emergence of resistant strains due to extended use of known antifungal drugs. Silver has become an important antimicrobial agent used in medical devices, cosmetics and even house-hold or clothing products. It is highly toxic and has a reduced risk of resistance. Silver nanoparticles have been broadly explored as an antimicrobial agent due to its high reactivity, large surface area and small size. They have been reported to display antimicrobial activity towards bacteria, viruses and fungi. C. neoformans is a pathogenic microorganism that possesses a number of virulence factors which increases the infectivity of the microorganism in immunocompromised individuals. Some of these include the presence of a polysaccharide capsule, melanin, urease and phospholipase production. Owing to limited availability of antifungal drugs and the possibility of drug resistance, this study focused on an alternative antimicrobial agent, namely silver nanoparticles, and the effects that silver nanoparticles had on fungal β-glucan, chitin and urease, phospholipase and melanin virulence factors. Results from our study show that silver nanoparticles inhibited the growth of C. neoformans at concentrations between 3.125 ƒM and 25 ƒM. Both 26.4 nm and 28.4 nm nanoparticles displayed growth inhibition, but were unable to kill the organism at concentrations of 200 ƒM and above. The silver nanoparticles caused a reduction in βglucan content. There was also an accumulation of intracellular ROS, and phospholipase activity, was reduced. In contrast, the organism displayed an increase in chitin content, melanin and urease activity upon exposure to the nanoparticles. This study shows that chemically synthesized silver nanoparticles are an effective antifungal alternative that greatly reduces or inhibits C. neoformans growth at very low concentrations (ƒM). For future studies it may be feasible to investigate the use of these nanoparticles in combination with known antifungal agents, to prevent the emergence of resistance and inhibit possible defense mechanisms displayed by the organism. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021
