- Description: The aim of this study was to develop a substantive grounded theory describing how Chinese immigrant entrepreneurs who own and operate small retail businesses in the Eastern Cape province of South Africa identify opportunities in the business environment. The substantive grounded theory was developed using the prescripts of grounded theory proposed by Strauss and Corbin (1990). In this respect, a substantive grounded theory called differentiating engagement of opportunity identification was developed from a sample of 41 qualitative interviews conducted with Chinese immigrant entrepreneurs. The study found that Chinese immigrant entrepreneurs identified various opportunities (startup, sales, operational, relational) in the business environment through their dynamic interactions and relationships with different stakeholders. These stakeholders mainly included family members, local employees and customers. The Chinese immigrant entrepreneurs displayed two interactional processes in their interactions with stakeholders, namely engaging in and disengaging from interactions. These interactional processes enabled the Chinese immigrant entrepreneurs to identify opportunities and operate their small businesses in the business environment. Assumptions held about the interactions and relationships with stakeholders in the host community were central to the interactional processes displayed by the Chinese immigrant entrepreneurs. As they operated their small businesses, the Chinese immigrant entrepreneurs would engage in interactions with customers who were perceived as favourable (approachable). From these interactions with favourable (approachable) customers, the Chinese immigrant entrepreneurs were able to identify opportunities (gaining customer insight of opportunity), whereas they would disengage from interactions with customers perceived as unfavourable (unapproachable). In this respect, they would delegate their local employees (actions of delegation in business) with the responsibility of interacting with unfavourable and hostile customers. Additionally, the Chinese immigrant entrepreneurs would engage in interactions with local employees to gain insight into local indigenous products and identify opportunities in the host community. In order to identify other opportunities (operational, relational), the Chinese immigrant entrepreneurs would disengage from interactions with local employees and engage in interactions with other stakeholders such as family members. The varying differentiated interactions and relationships established by the Chinese immigrant entrepreneurs with different stakeholders created a relational context which enabled the identification of opportunities in the host environment. Thus, the findings of the present study and the substantive grounded theory developed (differentiating engagement of opportunity identification) are discussed from the perspective of social capital, social exchange theory and Chinese cultural values. Finally, the theory developed in the present study contributes to the understanding of the processes of how social capital and relationships contribute to the process of identifying opportunities and operating a small business by immigrant entrepreneurs within a host environment.

- Description: HIV is regarded as one of the most devastating infectious diseases of the last few decades, and has a high prevalence in South Africa, subtype C being the most common. Palliative measures used to fight HIV involve the use various types of inhibitors, including the use of HIV protease inhibitors. Representatives from this class of inhibitors are gradually losing their efficacy due to development of resistance mutations from HIV-1. In this study, compounds from the South African Natural Compound Database (SANCDB) were screened against HIV-1 protease models generated from protease protein sequences belonging to 11 South African HIV patients before and after treatment with Lopinavir. The effect of Lopinavir on the alteration of drug-binding affinity before and after treatment is investigated by molecular docking of the protease against other FDA-approved drugs and detection of mutation types using the HIVdb tool. A network representation of hydrogen bonding between docked ligands and their receptor proteases has been developed and a profiling method of visualizing receptor-ligand docking energies at the local level is presented. Four potential HIV-1 protease inhibitors were identified from the list of 599 natural compounds on the basis of receptor conformation and binding free energy. Ligand stabilities were monitored by 20ns molecular dynamics runs using the GROMACS software.

- Description: Orientation: The manner in which Small, Medium and Micro Enterprises (SMMEs) perform is important for the sustainability of the enterprise. The role of strategic leadership on competitive advantage and innovation performance are investigated within this. Research purpose: To determine whether strategic leadership has an effect on competitive advantage and innovation performance in SMMEs. Secondly, to determine if innovation performance has an effect on competitive advantage. Motivation for the study: Contradictory views still exist on the concept of strategic leadership and its effect on competitive advantage and innovation performance and the effect of innovation performance on competitive advantage in SMMEs. This study contributes to these views within the South African SMME context. Research design, approach and method: A cross-sectional survey design was used and a questionnaire self-administered to a sample of 275 SMMEs in the Buffalo City Metropolitan Municipality drawn through simple random sampling from a population 950 SMMEs available from the Eastern Cape Development Corporation (ECDC) database. Main findings: The result showed that strategic leadership have a positive effect on competitive advantage and innovation performance in SMMEs. Furthermore, the results showed that there is a positive effect of innovation performance on competitive advantage in SMMEs. Practical implications: More is needed to develop strategic leadership. This can be done through leadership training and development, support from government of leaders of SMMEs and finally, a leader can take personal efforts to acquire competencies that allow them to make better decisions in managing the small business. Contribution: The study advances theory on leadership by showing its role on competitive advantage and innovation performance.
