"Soap operas as a platform for disseminating health information regarding ART and the use of 'reel' versus 'real' role models"

- 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.

"Why Persephone?" investigating the unique position of Persephone as a dying god(dess) offering hope for the afterlife

- 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.

'Becoming animal': motifs of hybridity and liminality in fairy tales and selected contemporary artworks

- 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.

In various African contexts and organisations, job satisfaction (JS) (Walumbwa et al. 2005) and organisational commitment (OC) (Gbadamosi 2003; Wasti 2003; Nyengane 2007; Pillay 2008) have been researched. 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.

'I always knew I would go to university': a social realist account of student agency: part 1

- 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.

- Description: The reaction of Zn(OAc)2 and C6H5COOH or 3,5-NO2-C6H3COOH with 3-ferrocenylpyrazolyl-methylenepyridine (L1), 3-ferrocenyl-5-methylpyrazolyl-methylenepyridine (L2), 3-ferrocenylpyrazolyl-ethylamine (L3) and 3-ferrocenyl-5-pyrazolyl-ethylamine (L4) afford the corresponding complexes [Zn(C6H5COO)2(L1)] (1), [Zn(C6H5COO)2(L2)] (2), [Zn(3,5-NO2-C6H3COO)2(L1)] (3), [Zn(3,5-NO2-C6H3 COO)2(L2)] (4), [Zn(C6H5COO)2(L3)] (5), [Zn(C6H5COO)2(L4)] (6), [Zn(3,5-NO2-C6H3COO)2(L3)] (7) and [Zn(3,5-NO2-C6H3COO)2(L4)] (8). These complexes behave as catalysts for the ring opening polymerization of e-caprolactone to produce polymers with molecular weight that range from 1480 to 7080 g mol1 and exhibited moderate to broad PDIs. Evidence of these complexes acting as catalysts was obtained from both the polymerization data and kinetic studies. The polymerization data show that variation of the [CL]/[C] from 100 to 800 produced PCL with relatively the same molecular weight indicative of a catalyst behavior. The appearance of induction period in kinetic plots strengthens the fact that these complexes are catalysts rather than initiators. MALDI-TOF MS and 1 H NMR data show di-hydroxy end groups, which support the coordination mechanism rather than insertion mechanism. To understand the broad PDIs obtained for some of the polymer, the electronic properties of the zinc complexes were investigated using cyclic voltammetry. The results show that the zinc complexes containing amine based ligands are highly electrophilic therefore making them unstable, hence the broad PDIs observed for zinc complexes containing amine based ligands. Among the eight complexes investigated, complex 7 is the most active catalyst with kp value of 1.18 107 h1 mol1 at 110 C.

- Description: How often do we notice the buildings that we work in, play in and live in? The architecture that we construct is specially geared to our human proportions, and shelters and accommodates us. It can be seen as a metaphor for the body, the self, and systems of social control that we have created. When the structure of this architecture is compromised, either literally or metaphorically, we experience instability and vertigo. My practical submission, Vertigo is concerned with architecture, perspective, deconstruction, instability, vertigo, scale and the body. Vertigo consists of paintings, ranging in scale from the size of a brick to the height of a single storey house. Utilizing a highly representational style as well as working with abstract sign systems and technical plan drawings, I destabilize firstly, our sense of certainty in the architecture that surrounds us, and secondly, prompts us to question the assumed fixity of ourselves and our social systems, through the convergence and collision of architecture and painting. This supporting document, (Un)stable Architecture as Deconstructed Meaning, considers the key conceptual concerns informing my practical submission. In chapter one of this mini-thesis: Deconstructivist Architecture, Instability and Impermanence I look at Deconstructivist Architecture which challenges traditional values of order, stability, harmony and unity of architecture. I position my work in relation to architecture projects on the Deconstructivist Architecture show in relation to their intent of undoing, shifting and destabilizing structure and what architecture is traditionally valued for. I also look at the shifting meaning and symbolism of architecture and skyscrapers. In the second chapter: Vertiginous Point of View and Shifted Perspectives I engage with vertigo, perspective, scale and the bodily analogy in architecture. I look at how Julie Mehretu destabilises built space and architecture in a painterly way, depicting multiple perspectives which are subjected to multiple interpretations. In chapter Three: Painting a Building and Building a Painting: Process, Scale and the Body, I discuss and engage with my practical submission, Vertigo, in relation to my process, scale, the body, vertigo, deconstruction, instability and perspective.

- Description: The modern era has brought the phenomenon of organisational change closer to the average person. With the recent financial crisis placing more strain on businesses, organisations are always under pressure to review their business models in order to deliver a sustainable operational model and as result, hopefully a sustainable competitive advantage. In order to remain competitive, the leadership team has to constantly seek ways of differentiating their organisations from others with similar product offerings. When these changes are initiated, there is no doubt that the leadership gave extensive thought prior to execution. However, their motives are not always clear to their most important constitution, their employees. Often when these changes are implemented, employees believe that they’ve been left out of the decision making process. Furthermore, post change review with employees are also not given enough thought and are often not done. This research used qualitative research methods to establish how employees experience job satisfaction and organisational climate subsequent to changes that transpired within their work environment. Semi-structured interviews and document analysis were used to collect data. The interviews were constructed by expanding upon well-documented quantitative dimensions of these behavioural variables. Questions were developed focusing on these dimensions in line with the changes experienced. The sample consisted of nine employees at an employee wellness organisation in Roodepoort, Gauteng. There is evidence to show that in this short period of two years (May 2012 to June 2014), by implementing various changes, the new leadership has improved the financial viability of the organisation. However, insights from the interviews point to a number of areas where the leadership and management structures have to exert more effort. Communication processes have to be reviewed, especially to lower levels. As there exists limited opportunities for promotion, investigations into expanding existing roles, again at the lower levels may assist in raising job satisfaction levels. Employees felt that support structures are severely lacking when significant changes affecting them are implemented. A climate for innovation and risk taking has to be considered which, if instituted, could aid the organisation in setting the pace for the organisational wellness industry. The structure adopted for this research consists of three sections. Section one follows the evaluation report format, with the literature review and research methodology sections following thereafter. By making use of established literature as a basis, the findings and recommendations are therefore not exclusively applicable to this organisation. Hence other organisations intending similar change initiatives could benefit from this research.

- Description: This case study was written within the broader concept of Organisational Culture and how it is integrated into an organisation to encourage responsible leadership. The core focus and emphasis of this approach is to establish the implications for businesses operating in the most challenging of commercial environments, while adhering to their corporate ethos and organisational values. These may be summarised with the phrase: Only a clean business is a sustainable business. This dissertation is intended to act as a case study and resource aide for the teaching of leadership, organisational behaviour, human resources and business sustainability. The study is about the Afghanistan chapter of the global giant Siemens, which has been working in many areas of specialisation conducting business in the country for more than 75 years. It has been selected for this case study because of its long-term impressive record, during which time it has developed and sustained a reputation as an organisation with a much-admired organisational culture, and one to which employees feel very closely attached and connected. This case study evolved from a set of unique as well as difficult circumstances. In Afghanistan, where infrastructure is weak, businesses and other structured organisations are in their initial and immature stages of development, and employee attachment to their workplaces is relatively weak. In the case of Siemens however, it has been much the opposite. It became apparent over a protracted period of time that the relationship of employees to the company was clearly of a positive and committed nature, unlike the general perception stemming from other multinational organisations operating within the country. Many business organisations in Afghanistan tend to emphasise to a lesser degree some modern-day practices of employer-employee relationships, which negatively affect motivation and commitment. The study grew out of the observations that employees of Siemens on the other hand, seemed to exhibit attitudes and commitments contrary to the general trend in the wider business sector. This project began with the intention to identify those factors contributing to employee loyalty and strong attachments to an organisation. Subsequently, the same findings were used to identify the traits and particular features working within the organisational environment.

A century of IsiXhosa written poetry and the ideological contest in South Africa

- Description: The central argument of this inter-disciplinary study is that IsiXhosa written poetry of 1912 – 2012 is a terrain of the struggle between the contending dominant ideologies of Segregation, Apartheid and Charterism (post-Apartheid); and the subordinate/ subaltern ideologies of Africanism, Charterism (pre-democracy), Pan- Africanism, Black Consciousness Movement and other post Apartheid ideologies. The study highlights the mutual relationship between the text and the context by focussing on the ideological contest which manifests itself in both form and structure (i.e. aesthetic ideology) and the content (i.e. authorial ideology) of the poetry of different epochs between 1912 and 2012. The study is located within the framework of Antonio Gramsci’s theory of cultural construction. Gramsci postulates that ideology and culture play a significant role in the process of asserting hegemony. Important concepts that constitute Gramsci’s theory of praxis are: ideology, culture, hegemony, organic intellectuals and both ideological and repressive state apparatuses. The first chapter presents the problem, the objectives, the methodology, and the scope of the study. The second chapter presents Gramsci’s theory of cultural construction and the work of scholars who developed his theory further. The tool that is employed for analysis and interpretation of textual significations of IsiXhosa written poetry is the revolutionary aesthetics, which is proposed by Udenta. The third chapter analyses and interprets literature of the epoch of 1912-1934 and exposes the contest between Segregation and Africanism ideologies. The fourth chapter contextualises and analyses the literature of 1934 – 1948, the second phase of contestation between Segregation and Africanism. The fifth chapter deals with literature of the first and second halves of the Apartheid epoch (1948 - 1973). The Apartheid ideology contested with the Africanist ideology which transformed into the Charterism ideology in 1955. In 1960 Pan-Africanism ideology and in 1969 Black Consciousness Movement ideologies entered the contest. The sixth chapter examines literature of the period 1973 – 1994 which is the second phase of the Apartheid epoch that ends with the “glasnost” period of 1990 - 1994. The seventh chapter studies literature of the democracy period of 1994 – 2012. The eighth chapter is the summary and general conclusion. The illumination of the nexus between culture and ideology during the past century (1912 - 2012) will provide insights that will assist us in addressing the challenges we face during the democracy period, and in the development on Arts and Culture in general, and literature in particular

- Description: An easily prepared solid state colorimetric probe for detecting the neurotransmitter dopamine (DA) was developed. The probe, in the form of an electrospun Nylon−6 (N6) nanofibre with embedded un−functionalized gold nanoparticles (UF−AuNPs) produces a clear colour change in the presence of a DA that is detectable by the naked eye. Characterisation of the nanofibre using UV/vis spectroscopy and electron microscopy (TEM) confirmed the formation of the AuNPs in the polymer solution, and that the AuNPs were completely encapsulated within the composite nanofibres before exposure to the analytes. The probe exhibited very high sensitivity towards DA resulting in colour change of the composite fibres from purple to navy blue/black even under low concentrations of DA. The probe was also selective to DA since the colour remained unchanged in the presence of commonly encountered interfering species such as ascorbic acid, uric acid, catechol, epinephrine and norepinephrine. Moreover, the colour change was observed rapid, occurring either immediately on contact with higher concentrations (5 x10−4 M) or within about 3−5 min for the lower concentrations (e.g. 5 x10−7 M). Since this probe does not require the use of any instruments, and is both rapid and stable over time, it can be applied in the field by an inexperienced person.

- Description: The international financial environment has become riskier due to the recent developments in product offerings and failure of regulation to keep abreast with these changes. The Global Financial Crisis exposed inadequacies of regulation, thus consensus on the need for comprehensive and uniform regulation was made by G-20 member states. Imposing exchange trading, clearing, reporting and capital requirements on the derivatives market are some of the ways of dealing with the problems caused by lax regulatory oversight. In this study, through the comparative analysis of derivatives regulation in South Africa, Brazil, India and Turkey, it was established that emerging countries are taking active steps to implement the G-20 agreement. Uniformity in the core rules was noted, with differences in the supportive legislation. Country specific rules which support the macroeconomic factors that are faced by these countries and the infrastructure available for regulatory execution are used amongst countries. The study concluded that current regulation in emerging countries is accommodative and regulatory differences are in line with economic factors in each country.

- Description: This work presents the synthesis and characterization of a new zinc phthalocyanine complex tetrasubstituted with 3-carboxyphenoxy in the peripheral position. The photophysical properties of the new complex are compared with those of phthalocyanines tetra substituted with 3-carboxyphenoxy or 4- carboxyphenoxy at non-peripheral positions. Three phthalocyanine complexes were encapsulated within silica matrix to form a core shell and the hybrid nanoparticles particles obtained were spherical and mono dispersed. When encapsulated within the silica shell nanoparticles, phthalocyanines showed improved triplet quantum yields and singlet oxygen quantum yields than surface grafted derivatives. The improvements observed could be attributed to the protection provided for the phthalocyanine complexes by the silica matrix.

- Description: In poor areas, where ICT infrastructure is being deployed with devel-opmental aims, there is a need to provide appropriate, sustainable technologies that meet the needs of the local community. Current trends for ICT interventions favour the use of mobile user equipment, such as tablets and cellphones, but we think that they are inappropriate to allow production as opposed to mainly consumption of digital con-tent, at least for the foreseeable future. Thus our objective is to reduce the cost of deployment of traditional communal Internet Access Points using PCs. In this paper we compare four candidate computers to be used as thin clients in such settings, according to seven different cate-gories. Our study identifies the strengths, weaknesses and problems of each device, and concludes with recommendations for anybody wish-ing to deploy such devices as Linux Terminal Server Project (LTSP) thin clients in a public Internet Access Point.
