- Description: Doreen Baingana’s Tropical Fish explores the migratory experiences of the main narrator-focalizer, Christine Mugisha, as she travels from Uganda to the United States of America. Although the analyses of home, exile, and migration by writers like Edward Said and Paul Tiyambe Zeleza tend to be ungendered; Baingana seems to elaborate on these concerns by reflecting on the gendered experience of travel. As Carole Boyce Davies has argued, the act of travelling and migration opens up new spaces and possibilities for black women writers as they come into contact with multiple places and cultures. In their encounters with migration, black women are able to negotiate and re-negotiate their identities. This article focuses on how Tropical Fish, interrogates complex, contradictory, ambiguous and often conflicted questions of home and migration with their concomitant issues of belonging and alienation/ estrangement and how they are intimately tied to the maternal bond.

“A Step Towards Silence”: Samuel Beckett’s The Unnamable and the Problem of Following the Stranger
- Authors: Marais, Mike
- Date: 2016

- Description: In this article, I argue that Samuel Beckett’s The Unnamable evinces the kind of aesthetic ambivalence that Theodor Adorno, in Aesthetic Theory, ascribes to the artwork’s location both in and outside of society. By tracing the metaphors used in the narrator’s depiction of the act of narration, I demonstrate that this novel self-reflexively articulates and meditates on its ambivalent position in society. Thereafter, I relate the work’s suspicion of its medium, and therefore its estrangement from itself, to its critique of community’s norms of recognition, which are embedded in language. Finally, I reflect on the potential effect of the text’s aesthetic ambivalence on the reader.

- Description: Sexuality education, as a component within the Life Orientation (LO) programme in South African schools, is intended to provide young people with knowledge and skills to make informed choices about their sexuality, their own health and that of others. Key to the programme are outcomes relating to power, power relations and gender. In this paper, we apply a critical gender lens to explore the ways in which the teaching of sexuality education engages with larger goals of gender justice. The paper draws from a number of ethnographic studies conducted at 12 South African schools. We focus here on the data collected from focus group discussions with learners, and semi-structured interviews with individual learners, principals and Life Orientation (LO) teachers. The paper highlights the complexities of having gender justice as a central goal of LO sexuality education. Teaching sexuality education is reported to contradict dominant community values and norms. Although some principals and school authorities support gender equity and problematize hegemonic masculinities, learners experience sexuality education as upholding normative gender roles and male power, rather than challenging it. Teachers rely heavily on cautionary messages that put more responsibility for reproductive health on female learners, and use didactic, authoritative pedagogical techniques, which do not acknowledge young people’s experience nor facilitate their sexual agency. These complexities need to be foregrounded and worked with systematically if the goal of gender justice within LO is to be realised.

- 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: publisher version , Drawing on the case of a small South African university which espouses a social justice approach to transformation, this chapter considers the possibilities and challenges created for student feedback within an institutional context that gives the individual lecturer a large degree of autonomy in evaluation. The chapter looks at some of the dominant perceptions of student feedback in addition to how it is collected and utilised, by referring to the institution’s policies and guideline documents; institutional research conducted with course coordinators; responses elicited from 40 lecturers on the issues outlined in this chapter; the author’s own reflections as a staff developer in the institution; and specific examples of good practice from lecturers situated within social science disciplines. The emerging concerns which structured this discussion are: the impact of student feedback on improving quality; enabling student voice; increasing student ownership; and the educational value of evaluation processes.

- 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.
