- Description: The more conventional route to synthesizing asymmetric push-pull phthalocyanines (Pcs) involves pairing electron-donating substituents with electron-withdrawing groups in either an A3B or AB3 manner. In this work, a push-pull system fashioned from a substituent bearing different functional groups was created. Symmetric and asymmetric cobalt and manganese Pcs in which acetaminophen was the dominant substituent were synthesized where the asymmetric analogues bore an alkyne-terminated substituent. These complexes were applied as sensors towards the electro-oxidation of nitrite. In addition to comparing the asymmetric Pcs to the symmetric counterparts, an assessment on the different central metals as well as the method of electrode modification was made. From the studies performed, the results showed that the manganese complexes are generally better suited (more so when clicked on to the electrode) in the electrocatalysis of nitrite with a limit of detection and a catalytic rate values of 2.15 μM and 6.91 × 106 s−1 M−1 being recorded for the asymmetric MnPc.

- Description: Confession is a central disciplining technology deployed in the second series of Intersexions, a popular South African TV series that seeks to change sexual and social behaviours that contribute to the risk of HIV infection. The article considers the ‘edu’ part of this edutainment programme, specifically with the nature of the lessons and with the form of ‘disciplining’ the narratives presuppose for gendered and sexual subjects. Central to this critical and constructivist exploration of the gender relationships that are validated and expurgated are Foucault’s notions of discourse and confession as a technology of self. We argue that the series presents a range of different gendered and sexual subjectivities but implicitly endorses a modern subjectivity and transformation at the level of the individual.

- Description: Malaria is an infectious disease caused by a diverse group of erythrocytic protozoan parasites of the genus Plasmodium. It remains an exigent public health problem in the tropical areas of Africa, South America and parts of Asia and continues to take its toll in morbidity and mortality with half of the world’s population under a permanent risk of infection leading to more than half a million deaths annually (WHO, 2013). Five Plasmodium species, namely P. falciparum (Pf ), P. vivax (Pv), P. ovale (Po), P. malariae (Pm) and P. knowlesi (Pk), are known to infect humans with Pf responsible for more than 90% of the malarial fatalities reported in sub-Saharan Africa. The predominance of Pf is attributed to its adaptability (Ashley, McGready, Proux, & Nosten, 2006; Prugnolle et al., 2011). Although the high occurrence of the Duffy negative trait among African populations lowers the threat posed by Pv, it is the most frequent and widely causative agent of benign tertian malaria in other parts of the world (Mendis, Sina, Marchesini, & Carter, 2001). In addition to the listed human malarial parasite forms, several other Plasmodium species, which infect non-human laboratory models, have been identified and are of significant importance in understanding the parasite biology, the host–parasite interactions and in the drug development process (Langhorne et al., 2011).

- Description: Smart, green, and resilient city paradigms have been mainly promoted through top-down and technocratic approaches. However, based on the notion to return to “the right to the city”, emerging community-driven initiatives are providing self-managed infrastructures contributing to urban sustainability transitions. This paper explores the relevance of the behavioral aspects of people-centered approaches in dealing with two different facets of urban metabolism: physical infrastructure (involvement with the management of decentralized infrastructures) and consumption patterns (involvement in proactive reduction of resources used). In the first case we assessed community perceptions about the roles, benefits, and willingness to proactively engage in the management of decentralized green infrastructures in Bogotá City, Colombia. For the second facet, we measured the effectiveness of change agents in re-shaping energy consumption decisions within urban social networks in South Africa and Saudi Arabia. This paper’s results show that pre-determined and standardized strategies do not guarantee positive, nor homogeneous, results in terms of meeting sustainability targets, or promoting community involvement. Hence, a better integration of people-centered and top-down approaches is needed through context-dependent policies, for enhancing both users’ appreciation of and commitment to urban metabolism participative management.

- Description: This study aimed to assess the impact of land use patterns on water quality and benthic diatom community structure and to test the applicability of diatom indices developed in other regions of the world to a small temperate southern African river system. Sampling was conducted at eight study sites along the length of the river on four separate occasions. Multivariate data analyses were performed on the diatom community dataset to specify the main gradients of floristic variation and to detect and visualize similarities in diatom samples in relation to land-use patterns within the catchment. One hundred and twelve (112) diatom species belonging to 36 genera were recorded during the study. Canonical correspondence analysis (CCA) demonstrated that variations in the benthic diatom community structure were best explained by ammonium, nitrate, conductivity, pH, temperature, resistivity and water flow. OMNIDIA was used for calculation of selected diatom water quality indices. A number of the indices, e.g., the trophic diatom index (TDI), eutrophication/pollution index and biological index of water quality (BIWQ), either under- or over-estimated the water quality of the system. With few exceptions, there were no significant correlations (p> 0.05) between the diatom indices’ values and the nutrient variables. The absence of any significant correlations between the diatom indices’ values and selected physico-chemical variables suggests that indices developed in other regions of the world may not be suitable for temperate southern African rivers.

- Description: The failings of classical Marxism, social democracy and anti-imperialist nationalism point to the need for a radical left politics at a distance from the state. This paper examines the impact, revival and promise of the anarchist/syndicalist tradition, a rich, continuous praxis in labour, left, anti-imperialist, anti-racist and egalitarian movements, worldwide, since the 1860s. Outlining its core ideas – anti-hierarchy, anti-capitalism, anti-statism, opposition to social and economic inequality, internationalist class-based mobilisation – and critique of mainstream Marxism and nationalism, it highlights the arguments there is a basic incompatibility between state rule, and bottom-up, egalitarian, democratic, socialist relationships. The anarchist/syndicalist project cannot be reduced to an organising style, protest politics or spontaneism: for it, transition to a just, self-managed society requires organised popular capacity for a revolutionary rupture, developed through prefigurative, class-based, democratic organs of counter-power, including syndicalist unions aiming at collectivised property, and revolutionary counter-culture. Success needs formal organisation, unified strategy and anarchist / syndicalist political organisations.

- Description: Ocean warming ‘hotspots’ are regions characterized by above-average temperature increases over recent years, for which there are significant consequences for both living marine resources and the societies that depend on them. As such, they represent early warning systems for understanding the impacts of marine climate change, and test-beds for developing adaptation options for coping with those impacts. Here, we examine five hotspots off the coasts of eastern Australia, South Africa, Madagascar, India and Brazil. These particular hotspots have underpinned a large international partnership that is working towards improving community adaptation by characterizing, assessing and projecting the likely future of coastal-marine food resources through the provision and sharing of knowledge. To inform this effort, we employ a high-resolution global ocean model forced by Representative Concentration Pathway 8.5 and simulated to year 2099. In addition to the sea surface temperature, we analyse projected stratification, nutrient supply, primary production, anthropogenic CO2-driven ocean acidification, deoxygenation and ocean circulation. Our simulation finds that the temperature-defined hotspots studied here will continue to experience warming but, with the exception of eastern Australia, may not remain the fastest warming ocean areas over the next century as the strongest warming is projected to occur in the subpolar and polar areas of the Northern Hemisphere. Additionally, we find that recent rapid change in SST is not necessarily an indicator that these areas are also hotspots of the other climatic stressors examined. However, a consistent facet of the hotspots studied here is that they are all strongly influenced by ocean circulation, which has already shown changes in the recent past and is projected to undergo further strong change into the future. In addition to the fast warming, change in local ocean circulation represents a distinct feature of present and future climate change impacting marine ecosystems in these areas.

- Description: Many coastal communities rely on living marine resources for livelihoods and food security. These resources are commonly under stress from overfishing, pollution, coastal development and habitat degradation. Climate change is an additional stressor beginning to impact coastal systems and communities, but may also lead to opportunities for some species and the people they sustain. We describe the research approach for a multi-country project, focused on the southern hemisphere, designed to contribute to improving fishing community adaptation efforts by characterizing, assessing and predicting the future of coastal-marine food resources, and codeveloping adaptation options through the provision and sharing of knowledge across fast-warming marine regions (i.e. marine ‘hotspots’). These hotspots represent natural laboratories for observing change and concomitant human adaptive responses, and for developing adaptation options and management strategies. Focusing on adaptation options and strategies for enhancing coastal resilience at the local level will contribute to capacity building and local empowerment in order to minimise negative outcomes and take advantage of opportunities arising from climate change. However, developing comparative approaches across regions that differ in political institutions, socio-economic community demographics, resource dependency and research capacity is challenging. Here, we describe physical, biological, social and governance tools to allow hotspot comparisons, and several methods to evaluate and enhance interactions within a multi-nation research team. Strong partnerships within and between the focal regions are critical to scientific and political support for development of effective approaches to reduce future vulnerability. Comparing these hotspot regions will enhance local adaptation responses and generate outcomes applicable to other regions.

- Description: This article draws on the author’s experience of teaching African Studies to undergraduate South African students in order to reflect on some of the key challenges facing teachers of African Studies, both in South Africa and beyond. In particular, it discusses challenges relating to teaching a field as contested as African Studies, looking at whether teaching African alternatives to mainstream African politics is helpful and at whether and how one can teach Africa in a way that encourages and develops critical thinking. The article also explores how the racial politics of the context in which one teaches African Studies inevitably affects the way in which students engage with the content of the course. While the article discusses these issues in relation to the South African higher education context in particular, implications for other contexts are also highlighted.

- Description: An Identity Document (ID) is needed by South Africans to study, apply for a pension or get married. However, Home Affairs, the state department responsible for issuing them, is poorly managed. The popular Daily Sun tabloid newspaper mediates for its five million working class readers the frustration caused by this incompetency in its “Horror Affairs” column. Readers tell their stories about (not) getting their IDs, stories often of suicide, depression and “giving up” on life. Using a Lacanian frame, and through a close reading of “Horror Affairs” texts, I argue that this tabloid plays a therapeutic role for its socially marginalised readers by mediating the “invisibility” engendered by the modernising state and its administrative technologies. Given the concern about high rates of mental health illness in South Africa, the research also demonstrates how popular culture forms can alert health care practitioners to issues which may otherwise go unnoticed.

- Description: My exhibition draws on Andreas Huyssen's notion of memory sculpture to articulate my own sense of loss and trauma, due to the divorce of my parents. Within my work I explore the effects that divorce had on me and how it has disturbed my normative understanding of home and family. I have created scenarios alluding to the family home that I have manipulated in order to convey a sense of nostalgia and loss. By growing salt crystals over found objects and/or cladding them in salt, I attempt to suggest the dual motifs of preservation (a nostalgic clinging to the past) and destruction (due to the salt’s corrosive properties). In this way, the salt-crusted objects serve as a metaphor for a memory that has become stagnant, and is both destructive and regressive. The objects encapsulate the mind’s coping methods to loss. In my mini thesis, I discuss characteristics of memory sculpture as a response to trauma, drawing on Sigmund Freud's differentiation between mourning and melancholia. I also unpack how objects and traces (such as photographs) may act as nostalgic triggers, inducing a state of melancholic attachment to an idealised past. I address these concerns in relation to selected works by Doris Salcedo and Bridget Baker, and also situate them in relation to my own art practice.

- Description: The media, through development communication and edutainment, plays a critical role in the transformation of societies. In line with this, this thesis discusses the extent to which commercially driven prosocial soap operas can provide a platform for public health messaging, in the context of the HIV/AIDS epidemic in South Africa, for antiretroviral treatment (ART) and for encouraging ART adherence to foster national development. Furthermore, this thesis examined the potential of celebrities as HIV/AIDS ambassadors and the potential of both fictional characters and ‘real-life’ celebrities to disseminate these health messages. Although the HIV/AIDS epidemic in South Africa is stabilising, this is not the time to relax the communication around the disease, particularly regarding adherence to ARVs, considering that South Africa has the largest ARV rollout in the world. The qualitative methodological approach taken for this thesis is a three-step approach examining the intended message, the text and the appropriated message by viewers. Firstly, a thematic content analysis of an episode of Isidingo, that illustrated Nandipha as HIV-positive and the side-effects that came with her ART adherence, and the 3Talk interview with Lesego Motsepe, where she announced that she was weaning herself off ART, was done in order to understand the intended health messaging in the soap opera and the health message disseminated by an HIV-positive actress with regards to ART. Thereafter interview responses by the production team as well as by HIV-positive viewers, using ARVs, were thematised. In addition media texts which provided commentary on the use of a celebrity as a HIV-positive role model were examined. In doing this, this thesis has offered up the meanings of how HIV-positive women taking ARVs and living in Makana experience and understand the media, particularly health messaging relating to ARVs. The findings of this study suggest that commercial soap operas are the perfect platform to address HIV/AIDS and that prosocial health messaging regarding ARV adherence is still necessary in this country. Soap operas have the potential to have an educational angle. Although, HIV-positive individuals serve as better role models as they are authentic; given human nature, fictional characters, such as Nandipha Matabane in Isidingo, may be more sustainable role models as their message can be scientifically-based and well-researched. Realistic characters serve as role models whose behaviour is to be emulated. Soap operas appeal to a wide audience and so storylines can be tailor-made according to the times and the needs in terms of health issues and messaging. Thus, soap operas are not a single platform but rather one which can be exploited to maximum advantage for public health messaging.

- Description: Persephone’s myth is unique, as it was the central narrative of one of the most prominent ancient mystery religions, and remains one of the few (certainly the most prominent) ancient Greek myths to focus on the relationship of a mother and her daughter. This unique focus must have offered her worshippers something important that they perhaps could not find elsewhere, especially as a complex and elaborate cult grew around it, transforming the divine allegory of the changing seasons or the storage of the grain beneath the earth, into a narrative offering hope for a better place in the afterlife. To understand the appeal of this myth, two aspects of her worship and mythic significance require study: the expectations of her worshippers for their own lives, to which the goddess may have been seen as a forerunner; and the mythic frameworks operating which would characterise the goddess for her worshippers. The myth, as described in The Hymn to Demeter, is initially interpreted for its literary meaning, and then set within its cultural milieu to uncover what meaning it may have had for Persephone’s worshippers, particularly in terms of marriage and death, which form the initial motivating action of the myth. From this socio-anthropological study we turn to the mythic patterns and motifs the story offers, particularly the figure of the goddess of the Underworld (primarily in the influential Mesopotamian literature), and the Dying-Rising God figure (similarly derived from the Near East). These figures, when compared to the Greek goddess, may both reveal her unique appeal, and highlight the common attractions that lie in the figures generally. By this two-part investigation, on the particular culture’s expectations and the general mythic framework she exists in, Persephone’s meaning in her native land may be uncovered and understood.

- Description: ‘Becoming Animal’: Motifs of Hybridity and Liminality in Fairy Tales and Selected Contemporary Artworks serves as a theoretical examination of the concept of the hybrid. My research unpacks the liminal aspect of hybridity, locating the hybrid in the imaginative world of popular fairy tales, folk lore and mythology. In my accompanying MFA exhibition, Becoming(s), I explore these motifs through an installation of mixed-media sculptures which are based on the hybrid creatures that populated the fantasy world of my childhood. The written component of my MFA submission will relate directly to my professional art practise, developing it further and situating it within a relevant context. In my mini-thesis I will consider the liminal in relation to the ‘animal turn’ in contemporary art, with a particular focus on relevant artists working with the motifs of hybridity, such as Nandipha Mntambo, Jane Alexander and Kiki Smith. The ‘animal turn’ is a term used by Kari Weil (2010: 3) to describe a contemporary interest in issues of the nonhuman, and in the ways that the relationship between humans and nonhumans is marked by “difference, otherness and power”. Of key concern to my research will be Giles Deleuze and Felix Guattari’s concept of ‘becoming animal’. Rather than describing a transition from one stable state to another, ‘becoming animal’ suggests a radical dissolution of boundaries – not just between species (such as ‘human’ and ‘animal’) but between any essentialising binaries. As such, ‘becoming animal’ suggests a conception of identity as being fluid and mutable, rather than stable and fixed.

Most of the previous research is quantitative in nature. Although quantititative research provides insights into the relationships between variables, it does not necessarily provide in-depth meaningful conclusions on micro-psychological levels (e.g. Sempane, Rieger & Roodt 2002; Buitendach & De Witte 2005).

- Description: This edited work has gathered together contributions on how to transform universities in South Africa; as many are struggling to shift their institutional culture. In a South African context, transformation means to attempt to change higher education institutions such that they no longer reflect the values promoted by apartheid but rather reflect the values embodied in South Africa's 1996 Constitution. Institutional culture is the main subject for discussion in this book. In order to transform South Africa's universities, the contributors begin by analyzing the idea of what a university is, and relatedly, what its ideal aims are. A second theme is to understand what institutional culture is and how it functions. Moreover, transformation cannot occur without transforming the broader cultures of which they are a part. Related to this theme is a general concern about how contemporary moves towards the instrumentalization of higher education affect the ability to transform institutions. These institutions are being pushed to conform to goals that are outside the traditional idea of a university, such as concerns that universities are being 'bureaucratized' and becoming corporations, instead of a place of learning open to all. In conclusion it can be said that the contemporary South African academic community has an opportunity to recreate itself as the end of apartheid created space for engaging in transformative epistemic projects. The transformation of the tertiary sector entails a transformation of institutional cultures.

- Description: Academic development programmes at higher education institutions (HEIs) in South Africa are often underpinned by discourses that view students as deficit. Archer's social realist ontology offers a means of understanding reflexivities and agency of students in the higher education context. Using narrative data and drawing on Archer's (2003) theory of mediation between structure and agency through internal conversations, this study examined the socio-economic background of one particular student, Thando, and his agential journey to arrive at the academy. The analysis reveals Thando has a deliberate and determined stance towards achieving his project of obtaining a tertiary education in order to realise a better life for himself and his family. Despite what could be perceived as constraining socio-cultural conditions, Thando strategically circumvents such restrictions and acts in ways that help him pursue his project. It is argued that student agency needs to take a more central place within academic development programmes in higher education.

- 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.
