- Description: The “tabloid TV” news genre is a relatively new phenomenon in Uganda and Africa. The genre has been criticised for depoliticising the public by causing cynicism, and lowering the standards of rational public discourse. Despite the criticisms, the genre has been recognised for bringing ‘the private’ into a public space and one of the major ‘private’ issues on the public agenda is women and gender equality. Given these critiques, this study set out to interrogate the meanings that young working class women in Kampala make of the tabloid television news programme Agataliiko Nfuufu and to ask how these meanings relate to the contested notions of femininity in this urban space. In undertaking this audience reception study I interviewed young women between the ages of 18-35 years by means of individual in-depth interviews and focus group discussions. The study establishes that Agataliiko Nfuufu is consumed in a complex environment where contesting notions of traditionalism and modernity are at play. The study also establishes that while mediating the problems, discomforts and contestations of these young women’s lives, Bukedde TV1 operates within a specific social context and gendered environment where Agataliiko Nfuufu is consumed. The study concludes that the bulletin mediates the young women’s negotiations and contestations, but it provides them with a window into other people’s lives and affords them opportunities to compare, judge and appreciate their own. Furthermore, the gendered roles and expectations in this context have become naturalised and have achieved a taken-for-grantedness. Therefore, patriarchy has been legitimised and naturalised to the extent that the respondents define themselves largely in relation to male relatives, and marriage. While the women lament the changes that have taken place in their social contexts which disrupt the natural gender order, they construct themselves as subjects of the prevailing discourses of gender relations that see men as powerful and women as weak and in need of protection.

- Description: This thesis examines the representation of home and hospitality in Zoë Wicomb’s Playing in the Light, Ishtiyaq Shukri’s The Silent Minaret, and Ivan Vladislavić’s Double Negative. It attempts to trace the un-homeliness of the central characters and to account for their feelings of discomfort. As such, it argues that the home is incapable of being inviolable because the invasion of the public is always a possibility. The implication is that master narratives such as race, history and politics are always entering the space one constructs as private. That said, this study also argues that the home and those things with which it is most closely associated, such as belonging, comfort and safety, may actually hide a form of violence. By this I mean that in the desire for homeliness, one may exclude others from one’s home. Consequently, this argument draws on Jacques Derrida’s writings on the aporia of conditional and unconditional hospitality to investigate what ethical possibilities might, somewhat unexpectedly, be created by the un-homely home. The study is therefore an exploration of the potentials that inhere in a certain kind of un-homeliness, the most important of which is the chance to respond ethically to the alterity of the other. In sum, there is a necessity to extend hospitality beyond condition and beyond limit, and this ethical imperative is at odds with the desire for comfort and safety. The way in which post-transitional novels explore these issues of hospitality and home is the primary focus of this study.

“There are certain things that I just know that I have to do because we are brothers”: a discourse analysis of young black men’s engagement with popular representations of brotherhood

- Description: The present study analyses the discourses that young black South African men employed when they engaged with popular representations of brotherhood in the media. In particular the study explores how these particular young men view masculinity within brothering and what the implications of ‘doing brothering’ are as a result of this view. Drawing on discursive psychology, the study is located in a social constructionist theoretical framework and uses a qualitative methodological approach. The data used in the discourse analysis was gathered through focus group discussion of scenes from the television show Generations. The discourse analysis produced two major discourses in which there were different constructions of masculinity each influencing the way in which brothering was done. The first discourse constructed a ‘dutiful man’ who performs his brotherly obligations separately from his emotions, this discourse is in line with discourses of hegemonic masculinity where men are expected to fulfil obligations and are not expected to be emotional. Resisting this discourse at times, some participants in this study did occasionally construct men as having rich emotional lives such that the quality of interaction with brothers is constructed as more important, in terms of building intimate fraternal relationships, than the amount of interaction with them. The second major discourse constructs the ‘ideal man’ in two different ways: as the ‘good man’ and the ‘unscrupulous man’. The ‘good man’, like the ‘dutiful man’ performs the obligations society has placed on him, but does not receive the social esteem that is given to the ‘unscrupulous man’, who is successful and financially powerful. Although both these types of men are spoken of as possessing masculinity, the ‘good man’ is constructed as holding onto a type of masculinity that does not have a place in contemporary society. The findings suggest that brothering informs the way in which men take up certain masculine positions. The study contributes to our understanding of the construction of gender identity within familial relationships, specifically the adult brother-brother relationship.

- Description: This thesis concentrates upon a new field of research in South African accounting scholarship – this being, in general terms, accounting history and more specifically an analysis of the origins of the Public Accountants’ and Auditors’ Board as watch-dog in relation to: ● the South African economy in the period 1913–1940; and ● the changing political framework (also in the period 1913–1940). The integration of economy, politics and personal ambition on the part of early 20th Century accounting societies, led to a variety of responses, counter proposals, stalemates and unfocused activity which caused the process of accountants’ registration to extend over 38 years in South Africa. This confusion was in strong contrast to the process of speedy registration of accountants in New Zealand and Australia. The final unification of South African accounting societies in 1951 created the Public Accountants’ and Auditors’ Board. Its creation, at long last, suggested an overarching control and regulation which was mirrored in the final political unification and economic stability of a South Africa dominated by Afrikaner Nationalists. One further element was interwoven into the fabric of the thesis – this being the application of institutional economic theory and its impact upon the accounting concepts of “material irregularity” and “reportable irregularity”.

Beyond greening: reflections on the business sustainability imperative

- Description: This paper sets out to reflect that organisations should go beyond greening and embrace the sustainability imperative. The concept of greening and environmentalism reached a ceiling as it focuses only on short-term green issues rather than on long-term sustainability goals. Narrow concerns for the natural environment often dilute the true meaning of sustainability. Yet, the field of sustainability is much broader than just focusing on environmental issues. Most contemporary executives know that their response to the challenges of sustainability could seriously affect the competitiveness and survival of their organisations. Despite this notion, most are failing by launching a few greening initiatives without a clear sustainability vision and plan. The sustainability discourse expanded the manner in which organisational success is measured, using values and criteria from the economic, environmental and social realms – commonly known as the triple bottom line. The idea is to balance the needs of people, the planet and the organisation’s profits to create long-term shareholder value. The concept of sustainability has suffered from a proliferation of definitions, meaning many things to different people. However, consensus is forming that sustainability refers to the process by which sound economic systems operate well within the biophysical constraints of the ecosystem to provide a good quality of life that is socially appropriate for current and future generations. Sustainability is bigger than a publicity stunt, green products or occasional acknowledgement to on-going efforts to save the planet. Although greening will be a central part of the way business is conducted, green alone is not a broad enough platform to sustain a business in the long-run. There is a need to look beyond the green aspects of sustainability and also using the social, economic and cultural aspects to build a successful and sustainable organisation. 2 This paper addresses aspects such as the sustainability paradigm, dimensions and drivers of sustainability, statistical evidence of sustainability, national framework for sustainable development in South Africa, a sustainability case example and challenges of sustainability.

- Description: The photoelectrochemistry of metallo-octacarboxyphthalocyanines (MOCPc, where M = Zn or Si(OH)2) integrated with MWCNTs for the development of dye-sensitized solar cells (DSSCs) is reported. The DSSC performance (obtained from the photo-chronoamperometric and photo-impedimetric data) decreased as ZnOCPc > (OH)2SiOCPc. The incorporation of the MWCNTs on the surface of the TiO2 film (MOCPc–MWCNT systems) gave higher photocurrent density than the bare MOCPc complexes. Also, from the EIS results, the MOCPc–MWCNT hybrids gave faster charge transport kinetics (approximately three times faster) compared to the bare MOCPc complexes. The electron lifetime was slightly longer (ca. 6 ms) at the ZnOCPc systems than at the (OH)2SiOCPc system (ca. 4 ms) meaning that the presence of the MWCNTs on the surface of the TiO2 film did not show any significant improvement on preventing charge recombination process. , Original publication is available at http://dx.doi.org/10.1007/s10853-013-7710-1

- Description: The modification of the glassy carbon electrode (GCE) was carried out using two methods. The first method is simultaneous electropolymerization and electro-click followed by immersion into a solution of dimethyl formamide (DMF) containing FeTCPc. The second method is step by step whereby electropolymerization is carried out first followed by electro-click and then immersion into a DMF solution containing FeTCPc. From the electrochemical characterization, it was observed that the second route (step by step method) was the best as indicated by the ferricyanide studies (cyclic voltammetry and scanning electrochemical microscopy). In the electrooxidation of hydrazine, we obtained a potential of 0.26 V. Of interest were the detection limit of 6.4 μM and the catalytic rate constant of 2.1 × 109 cm3 mol−1 s−1. This shows that the sensor can be used for the electrooxidation of hydrazine. , Original publication is available at http://dx.doi.org/10.1016/j.electacta.2014.09.011

- Description: This paper reviews current and future trends and challenges in the field of consumer health informatics. Emergent innovations driving consumer health informatics in the information age include devices, tools and applications supporting personalised healthcare, electronic personal health record (PHR) systems and a plethora of tools in the health social media domain. Within this domain, a new kind of social media citizen, the consumer specialist or patient opinion leader, is taking the lead in online communities of patients. A new generation of personal health records combining PHRs and social media is emerging, even though pervasive adoption and use of PHRs remains elusive. The accuracy of information, security and privacy of personal health information, legislative matters and the digital divide remain recurring challenges of consumer health informatics. In future, PHR vendors will have to address the lack of espousal of PHRs in innovative ways to provide a compelling case for adoption. The continued uptake of health social media necessitates efforts to understand, through longitudinal studies, precisely who the users are, what they use it for and how it contributes to the achievement of both personal and public health outcomes. Health information consumers, of varying levels of techno-literacy, needs and preferences, must be assisted to move from simply accessing information to distilling relevant and credible information and making informed decisions. Further research is required to understand the changing relationships between patients and healthcare providers and how consumer health information technologies can best support these. There is a need to evaluate the effectiveness of consumer health information technologies to inform both public policy and the next generation of tools, technologies and artefacts that could better facilitate improved health outcomes. Lastly, more effort is required to erode digital inequalities. As we move into a future emphasising both the global and the individual, accelerated connectedness and speed of change, consumer health informatics must respond such that it remains germane and amplifies the value that can be gained by all stakeholders.

Characterization of the nanocomposites was done by transmission electron microscopy (TEM) and X-ray diffraction (XRD) analyses. Cyclic voltammetry (CV) was used for electrochemical characterization of the prepared nanocomposite for oxygen reduction reaction. The oxygen reduction activity for rGNS/CdSe-CoPyPc nanocomposite was found to be superior over the individual nanomaterials in this study. The activity of the nanocomposite towards oxygen reduction was also tested for tolerance to methanol crossover effect using chronoamperometry (CA) and electrochemical impedance spectroscopy (EIS) studies. , Original publication is available at http://dx.doi.org/10.1002/elan.201400372

The modified electrode is represented as rGNS-2-MWCNT-CoTAPc-GCE. X-ray photoelectron spectroscopy, transmission electron microscopy, scanning electrochemical microscopy and Raman spectroscopy were used to explore into surface functionalities, morphology and topography of the nanocomposite. The rGNS-2-MWCNT-CoTAPc-GCE had a low limit of detection of 3.32 × 10−8 M towards the detection of paraguat as a test analyte.

- Description: The main purpose of this study is to explore the factors that contribute to occupational stress as experienced by the Student Support staff in a Further Education and Training (FET) College in the Southern Cape. The Student Support staff has displayed many symptoms of stress over the past few years. This in turn has led to absenteeism, change in staff temperament, their feelings towards the College, motivation levels and a significant change in the staff’s day to day operations. Although the Head of Department for Student Support Services has engaged with the staff on numerous occasions to discuss the reasons for their experience of stress, no substantial reasons could be established in order to make the necessary changes in the department. No interventions that have been implemented to date have relieved the staff’s experience of stress. The researcher chose to use a qualitative, exploratory, descriptive and contextual research design to gain insight into the situation or phenomenon in order to identify the factors contributing to occupational stress and to identify measures that can be implemented to reduce occupational stress in the Student Support staff. The participants in this research included at least 10 Student Support staff within the Student Support Services Department at a Further Education and Training College in the Southern Cape. Purposive sampling was used in this research study. Interviews will continue until data saturation is achieved. The staff members must have been employed for at least one year in the Student Support Services Department. The researcher will make use of semi-structured interviews, observations and field notes. The data will be systematically collected and meanings, themes and general descriptions of the experience analysed within the specific context (de Vos, Strydom, Fouche & Delport, 2005). The researcher will make use of Tesch’s method of analysis, and use Guba’s strategies for ensuring Trustworthiness. The researcher will apply the ethical considerations of confidentiality, informed consent, ethical approval from relevant institutions, avoidance of harm to participants, truthfulness and the debriefing of participants when conducting this study. The findings were reported as three major themes and subthemes. The three major themes were; Student support staff identified several factors that contributed to occupational stress, Student support staff identified the effect that occupational stress has on them, Student support staff offered suggestions that the college could implement to reduce occupational stress. These themes were discussed and analysed in-depth.
