- Description: Higher education in South Africa is faced with a paramount task to help erode the social and structural inequalities that have been inherited from the Apartheid system (Department of Education 1997; Council on Higher Education 2000:12). The findings from the Soudien Report (2008:116-117) point out that the post-Apartheid higher education system in South Africa is characterised by various forms of discrimination and institutional cultures that marginalise some members of institutions resulting in pervasive feelings of alienation. In the South African higher education field, the concept of a “home” for all has been used by a variety of commentators to depict a vision of what transformed, inclusive higher education institutional cultures might look like. In this thesis, I interpret the experiences of residence life on the part of gay, lesbian and bisexual students on a largely residential campus. I ask how gay, lesbian and bisexual students experience being “at home” in the campus’s residence system. The thesis is based on 18 in-depth qualitative interviews with students who self-identify as gay/lesbian or bisexual who have experienced residence life on the campus for a period longer than six months. A wide literature exists on the concept of “home”. Drawing from many different disciplines including anthropology, history, philosophy, geography, psychology, architecture and sociology, I distil the essential features of “at homeness” as incorporating comfort, privacy, security, acceptance, companionship and community. The research was concerned to inquire into how central the idea of home is to human flourishing and then into how gay, lesbian and bisexual students are routinely denied many of the essential comforts associated with being “at home” that heterosexual students have the privilege of taking for granted.

- Description: Zn octacarboxy phthalocyanine-reduced graphene oxide or graphene oxide conjugates were characterized by absorption spectroscopy, transmission electron microscopy, fluorescence spectroscopy, X-ray diffraction, thermo gravimetric analysis and X-ray photon spectroscopy. The presence of reduced graphene oxide or graphene oxide resulted in the quenching (turn on) of Zn octacarboxy phthalocyanine fluorescence which can be explained by photoinduced electron transfer. Zn octacarboxy phthalocyaninereduced graphene oxide or graphene oxide conjugates “turned on” fluorescence showed a linear response to hydrogen peroxide hence their potential to be used as sensors. The nanoprobe developed showed high selectivity towards hydrogen peroxide in the presence of physiological interferences.

- Description: This article aims to develop the concept of ‘meaningful engagement’ in terms of the contemporary language policy implementation framework in South Africa. By exploring the current language policies, implementation and the current lack of effectiveness, the authors offer a new implementation focus drawn from the legal concept of ‘meaningful engagement’. ‘Meaningful engagement’ is a concept within the socio-economic rights sphere. This article expands and advances the concept within a language policy framework. Against the enabling legislative environment created by the Use of Official Languages Act 12 of 2012 and the overarching Constitutional framework which embeds the rights of all official languages, ‘meaningful engagement’ is developed and applied to selected language policies and practices.

- Description: Gesture recognition has become a preferred approach to the control of various systems. This allows users of the system to interact without having to use any controls or equipment. This paper investigates the use of gesture recognition in order to select and transport audio tracks over an Ethernet AVB network to speaker endpoints. The research uses equipment that is commercially available and relatively cost efficient. The endpoints receive audio samples that are encapsulated within network packets and processes them. The audio tracks are mixed at the endpoints according to gain ratios that will change and be different for each endpoint.

- Description: Aim: To review the impact of the human immunodeficiency virus and antiretroviral therapy on the vasculature. Objectives: This review seeks to identify the burden which the human immunodeficiency virus and antiretroviral therapy have on the vasculature. Method: Medline/PubMed and Google scholar were searched. There were over 100 publications reviewed. Some people who worked in similar fields were also contacted. The present review summarized current understanding of Human immunodeficiency virus, antiretroviral therapy and effect on the vasculature such as arterial stiffness. Atherosclerosis, endothelial dysfunction, the strengths and weaknesses of current testing strategies, and their potential applications in clinical research and patient care. The association of inflammatory biomarkers, blood pressure and ageing with arterial stiffness were also reviewed. Conclusion: Available literature shows that HIV and antiretroviral agents have a great impact on the vasculature and its progression.

- Description: My lecture this afternoon is titled “Family business: A legitimate scholarly field”. I will first provide you with some background to family businesses and their prominence and contributions worldwide. This will be followed by an overview of how the field has evolved and where it is today. I will highlight the key role players in this evolution, some of the main challenges facing the field as well as the reasons why scholars study these businesses. I will conclude by highlighting how I believe that research on family business in South Africa can contribute to the field as a whole.
