  • Description: The study sets out to investigate elections as drivers to political instability in Africa, using Lesotho as a case study from 2012 to 2017. It employs primary and secondary sources of data. The period is of interest for two reasons. Firstly, the continuing instability post three successive free and fair elections, and secondly, the advent of Coalition Governments. The structure adheres to two theoretical frameworks namely, a) Huntington’s two turn-over test and, b) Karl’s Fallacy of Electoralism. In order to investigate how elections could or could not be drivers to political instability, the researcher looked at the different forms of political instability in Lesotho. These include attempted coup d’état, assassinations and violation of territorial sovereignty. The later form being peculiar to the period under study as the other forms had occurred at some stage through the political history of this country. It further asserts uncertainty of hung Parliament and politicised institutions as attributes to the recurrence of political instability. It concludes that Lesotho is a deviant case from the two turn over test. The scope of the study supports the fallacy of electoralism. Several recommendations have been presented. These include that Government of Lesotho should amend the Constitution on the functions and powers of the King, Politicians should implement the promises they made to the electorates during campaigns, and regulate or abolish floor crossing in Parliament amongst others.

  • Description: Unethical conduct takes root and largely flourishes in environments devoid of compliance with SCM laws, regulations and sound corporate governance values and principles. Ethical conduct is a prerequisite of good governance and sound municipal financial management. Unethical conduct in SCM leads to a loss of public trust and confidence in the management of public affairs. Despite the existence of control and oversight structures and processes for monitoring compliance with ethical standards, norms and regulations in SCM, procurement and contract management processes, BCMM still flouts SCM regulations. This leads to non-compliance with precincts of SCM policy regulations, the MFMA, as well as the Municipal Systems Act (MSA). Lack of adequate and effective control and oversight measures further exacerbates the problem, leading to poor management of procurement systems as well as inconsistencies in the disposal and delivery of services. Effective control and oversight often results in the reduction of waste, eradication of corruption and improvement of municipal financial performance, as well as improved ethical conduct, integrity, transparency and accountability. Qualitative approach was used to gather data using interviews and secondary sources in the form of official documents to explore the extent to which control and oversight measures for ethical conduct in Supply Chain Management are effective in Buffalo City Metropolitan Municipality. The data is to be analysed using content analysis and filtering techniques. Challenges that are affecting the effective management of Supply Chain in Buffalo City Metropolitan Municipality were brought forth and recommendations to improve Supply Chain Management in Buffalo City Metropolitan Municipality are examined in this study.

  • Description: The motivation for this study originated from the problem of children who are victims of rape in the victim support centers. The researcher became aware that most of the children needs more support services for counseling and after care services. The goal of the research was to explore the psychosocial challenges faced by children who are victims of Rape in the victim support Centre. The aim of the study was to determine the psychosocial effects (effects. challenges, support services they receive from professionals) as victims of rape in a victim support center. It was a case study of KwaNobuhle Area, Eastern Cape. The purpose was to identify gaps as there are minimal services rendered to children as rape victims in the victim support Centre. In order to meet the objectives of the study, interviews were conducted to 20 victims of rape (both boys and girls) as well as 6 different professionals working with rape cases from the arrival of the child from the opening until the finalization of the case. Data were analyzed according to the qualitative data - analysis procedures. The researcher utilized the phenomenological research design. The research domain where the interviews took place was at the KwaNobuhle Area under the Department of Social Development jurisdiction. In this study, 20 Xhosa speaking children of different ages, gender, educational standards, and socio-economic backgrounds as well as those who suffered different types of rape, as defined by the Sexual Related Matters Act 32 of 2007; they were all interviewed through the use of a semi-structured interview schedule. The participants were purposively selected as they were all at the victim support center. It has been found that some services are not provided within and are other professionals lack knowledge on how to work effectively with children as victims of rape To add on, the theoretical framework that was used in this study is the victim empowerment theory. This was used as a way of empowering the children who are victims of rape in the Victim Support Centres. The study found out that children who are victims of rape in the Victim Support Centres face psychosocial challenges for instance emotional, educational and behavioural challenges. Furthermore, the study also found out that there are few pschologists in the Victim Support Centres. Therefore, the study recommend that more psychologists should be employed at the Department of health and be placed in Victim Support Centres. More, so, there should be constant supervision and guidance on the care givers within the institution on how to effectively deal with the children who are victims of rape in VSC to avoid psychosocial challenges.

  • Description: Malaria is a deadly disease and its drug resistance has been reported to be a challenge globally. The death toll caused by malaria has increased rapidly in different regions of the world. Quinoline scaffold molecules are combined with other classes of antimalarials to tackle drug resistance. The combination of quinoline scaffolds with other antimalarial compounds and metals-based drugs have been reported to be a potential approach to overcome drug resistance common in the currently used antimalarials. 4-Aminoquinoline was hybridized with selected organic molecules and metal-based compounds to form a class of hybrid compounds containing either an amide bond or ester bond as a linker between the parent molecules. 4-Aminoquinoline derivatives are known compounds and they were prepared via known synthetic routes and characterized. The hybrid compounds were characterized and the FTIR results confirmed the successful linkage of 4-aminoquinoline derivatives to selected organic scaffolds to form hybrid compounds. NMR results confirmed the successful formation of hybrid compounds. MS showed signals of the hybrid molecules confirming the successful isolation of the hybrid compounds. In vitro antiplasmodial assay was performed against asexual parasite and chloroquine was used as a reference drug. The percentage inhibition effects of the hybrid compounds were in a range of 96-102% at 5 µM and 36-96% at 1 µM suggesting that the percentage inhibition effect of the hybrid compounds was influenced by the drug concentration. Hybridization of either 4-aminosalicylic scaffold or ferrocene butanoic acid with 4- aminoquinoline derivatives is a potential synthetic route that can result in potent antimalarials. However, more research is needed to fully understand the structure-activity relationship of these hybrid compounds.

Exploring a genre-based pedagogy in the teaching of writing explanation texts in a Grade 11 ESL classroom: an action research case study

  • Authors: Nekondo, Linus Vaakohambo

  • Description: This thesis reports on an action research case study into the use of a genre-based approach (GBA) in teaching the writing of explanation texts to Grade 11 learners in Ohangwena Region, Namibia. Knowledge of how to write different genres is a requirement of the Namibian curriculum, and in particular the Grade 11-12 English Second Language [ESL] syllabus. The study aimed to improve my pedagogic practice in the teaching of genre as an English Second Language [ESL] teacher. It also aimed to further develop my Grade 11 learners’ academic language proficiency in genre writing. I employed two action research [AR] cycles. The first cycle was aimed at establishing learners’ baseline proficiencies with regards to writing explanation texts. The second was then aimed at strengthening the weaknesses I identified in my first cycle. Theoretically informed by the genre and socio-constructivism theories, and following the recommended stages of the genre pedagogy cycle, I designed a GBA lesson unit comprising seven lessons. The lessons spanned a two week period. I used formative assessment to assess my learners’ activities during each lesson using marking rubrics designed in line with the structural and linguistic conventions of explanation texts. Data sources include document evidence from my learners’ pre- and post- instruction written works, my written reflections on the teaching/learning process from my research journal, my learners’ written reflections on each lesson, and the whole class closing discussion. The data revealed that, prior to the GBA intervention, while my Grade 11 learners possessed some skill in writing shorter explanations for content subjects; they lacked deep knowledge for so doing in ESL. The post GBA intervention data revealed that, by interacting with texts and working collaboratively in unpacking the features of the genre, learners were able to develop a more critical awareness of the generic and linguistic features of written explanation texts. The study concludes that learners’ genre writing skills can be strengthened through using a GBA approach in which they are immersed in the relevant text features and provided with appropriate assistance and feedback.

  • Description: Drug and substance abuse amongst secondary school children is a universal phenomenon and it has increased at an unprecedented rate over the past decade and still rising. In South Africa, drug and substance abuse has continued to ruin the youth and subsequently education despite various measures taken to stop it. This study aimed at investigating teachers’ views and experiences on drug and substance abuse by learners. Teachers have a responsibility to ensure that learners do not involve themselves in the use of drugs and substances at school. A case study research was conducted to investigate the views of eight teachers in two selected rural secondary schools in the King William’s Town Education District. Qualitative research guided the research process and the interpretivist paradigm served as bases for data collection. Face-to- face semi-structured interviews and focus group discussions were used to collect data. It emerged from the data that alcohol and substance abuse by learners have a negative effect on their academic work as learners abusing drugs could not concentrate on their studies and bunk classes. The data also showed that learners become violent and most of the time important time that could have been spent teaching is lost dealing with alcohol and substance abuse users. The findings also indicated that there was a lack of parental and community support to effectively deal with drugs in schools. From the findings it can be concluded that there are serious social and academic problems that are caused by drug and substance abuse in the rural schools. It can also be concluded that teachers and school managers had no clear and coherent strategies to deal with drug and substance abuse in schools. In view of the above, I recommend that a comprehensive model should be adopted to fight dug and substance abuse by learners.

  • Description: It is without a doubt that machine learning has been the area of focus in early days of artificial intelligence, but the early neural networks approach suffered some shortcomings and this led to a temporary decline in research capacity. New symbolic learning techniques have emerged since then which have yielded promising results and have led to a revival in research in machine learning. This has seen many researchers focusing on these techniques and experimenting with them by comparing their performances for different applications. With that in mind, the research thus decided to make an analysis of the symbolic approach against other approaches such as the neural network (connectionist) to evaluate the power of the former approach. This was done by first generating an ontology that acted as a representation of some collected indigenous knowledge. It is from this ontology that a dataset was generated. The dataset was made ambiguous to see the learning power of classifiers in such data. Two experiments were done, one using WEKA and the other using Orange as tools. The reason why the two experiments were used is because there was not a single tool which contained all the required learning algorithms. The research wanted to make use of ID3 and CN2 symbolic algorithm. However, WEKA had ID3 and not CN2 while Orange had CN2 and not ID3. The most important attributes from the ontology regarding the indigenous knowledge were the name of the plant, the province it is found and the disease the plant treats. Therefore the dataset had two features which were disease and province and one label which was the name of the plant. The learning algorithm was to use the two features to generate rules used to predict the label. However, there was ambiguity on the dataset. The challenge was that two different labels would contain the same features, thus leading to wrongful classification. This was the core of the research. Even though the learning model concluded this situation as wrongful classification, in real time, a system using the same learning model would provide desired and correct results. The only flow which was there is that the learning model simply used one label to predict under and ignore the other label with similar features. This was identified as a flow for both symbolic and non-symbolic algorithms. There is no way of giving suggestions in the case a user wants a different plant but with similar features. Therefore for classification using an ambiguous dataset, both these approaches proved to have the fore mentions flow. The research then decided to use recall to analyze the power of these approaches. It was discovered that ID3 has better recall than Multilayer perceptron and Naïve Bayes algorithms when using a training set. ID3 managed to recall clearly and effectively three of its classes by a probability of 1 while Bayes Net had only one class with recall probability of 1. To further investigate the issue of recall, cross validation was used to contrast the competence of recall of the three algorithms to strengthen the assertion that indeed ID3 has a better recall as compared to the other two algorithms. Three stages of cross-validation were done, one stage using 10 fold, the other 20 fold, and the last using 50 fold. For all the different stages of crossvalidation, Bayes Net proved to perform better in terms of recall than the other two algorithms. In cross-validation, MLP could recall approximately above 88% of the instances available in contrast to when using training set where the algorithm recall only two out of 18 instances. In overall the symbolic approach proved to be a commendable approach for use over the nonsymbolic approach. The study of machine learning involves the building of learning algorithms, improving upon learning algorithms or making comparisons of machine learning algorithms. The research raised awareness on some improvements that need to be done on not only symbolic algorithms but non-symbolic ones as well. Some improvements include improving on or coming up with algorithms that suggest alternative predictions in cases of ambiguity instead of doing wrongful classification and not reflect on other possibilities.

Being for the Other: Surveillance and Depictions of Race, Gender, and Animals in Contemporary South African Fiction

  • Authors: Laue, Kharys Ateh

  • Language: English
  • Type: Thesis , Masters , MA

  • Description: This thesis examines the depiction, in contemporary South African fiction, of irresponsibility and responsibility in relation to the raced, gendered, and animal Other. Through a close analysis of Jeremy Bentham’s Panopticon prison and Michel Foucault’s study of this design, I establish the notion of disciplinary surveillance or panopticism. This I take to be a mode of power that seeks, by means of an invisible gaze, to render its subjects docile. In my readings of J. M. Coetzee’s Waiting for the Barbarians, Zoë Wicomb’s Playing in the Light, Justin Cartwright’s White Lightning, and selected short stories from Wicomb’s You Can’t Get Lost in Cape Town and The One That Got Away, I demonstrate that oppressive authoritarian regimes are rooted in Benthamic principles of hyper-visibility and concealment. Disciplinary power, I contend, is effective precisely because it places an individual in a constant state of Being-for-Others, a term coined by Jean-Paul Sartre to describe the experience of objectification through another’s look. Judith Butler’s concept of gender performativity and W. E. B. Du Bois’s notion of black double consciousness frame my examination of, respectively, gender and racial oppression, while my discussion of animals appeals to Jacques Derrida’s work on the non-human. I show how surveillance, in each of the selected texts, functions through a racist and/or sexist and/or speciesist gaze that facilitates violent, irresponsible relationships with the human and non-human Other. The texts under discussion, however, also depict ways in which the Other actively resists and subverts regimes of oppression, often by means of a counter gaze that compels the protagonist, or the reader, to take up responsibility for Others. Ultimately, my study concludes that the fictional works of Coetzee, Wicomb, and Cartwright offer an ethics of empathetic responsibility, which I term Being for the Other, in opposition to mechanisms of disciplinary surveillance that seek to oppress, conceal, and dominate.

Exorcising the Past: History, Hauntings and Evil in Neo-Gothic Fiction

  • Identifier: vital:2333 , http://hdl.handle.net/10962/d1021257
  • Description: This thesis explores the conventions of both historical and Gothic fiction in order to investigate what seems to be a recurrent impulse to exorcise the past in what I define as contemporary Neo-Gothic fiction. It therefore attempts to establish a distinction between Neo-Gothic fiction and other forms of contemporary Gothic fiction by focusing on the treatment of history, the supernatural and the grand narrative of progress in three contemporary Gothic novels: The Little Stranger by Sarah Waters, The Historian by Elizabeth Kostova and The Accursed by Joyce Carol Oates. This thesis argues that the most potent manifestation of history can be found in the representation of the revenant in Neo-Gothic fiction, which exhibits a disruptive and evil ontology that problematises the exorcism of the past. Furthermore, the reactions of ‘modern’ characters to these revenants illustrate the imperative to exorcise the past, and therefore the treatment of history and the past is reflected in the interaction between the ‘modern’ characters and the Gothic revenants. Through this interaction as well as the parody of traditional Gothic and historical fiction conventions, Neo-Gothic fiction constructs a critique of the Enlightenment’s grand narrative of progress. Paradoxically, this constitutes Neo-Gothic fiction’s own attempt to exorcise the past, which it recognises in a simplified and reductive narrative of history propounded through the grand narrative of progress. This thesis therefore pays particular attention to the configuration of revenants as evil and ‘modern’ humans as good, and the disruption of this simple binary that is effected through Neo-Gothic fiction’s subversion of the grand narrative of progress. This focus allows for the theorisation of the revenant through Jacques Derrida’s notion of ‘hauntology’ and Julia Kristeva’s ‘the abject’, the investigation of the treatment of history in Neo-Gothic fiction and the exploration of very recent Gothic texts that have not yet received much critical attention.

  • Description: Bull sharks (Carcharhinus leucas) are globally distributed top predators that play an important ecological role within coastal marine communities. However, little is known about how the spatial and temporal scales of their habitat use are associated with their ecological role. In this study, a population of sub-adult and adult bull sharks were investigated within a remote subtropical marine community in the southwest Indian Ocean off the coast of southern Mozambique. The main objectives of the study were to test a minimally invasive remote biopsy sampling method; to investigate the feeding ecology of bull sharks; and to investigate the temporal and spatial scales of bull shark residency patterns and migration dynamics. Biopsy tests on free-swimming bull sharks showed that the devised sampling technique provided a minimally invasive and consistent method (biopsy retention rate = 87%) to obtain muscle tissue samples sufficiently large enough (310±78mg, mean ± SD) for stable isotope analysis. Results from the stable isotope analysis showed that adult bull sharks appeared to exhibit a shift towards consistentlyhigher trophic level prey from an expanded foraging range compared to sub-adults, possibly due to increased mobility linked with size. Additionally, bull sharks had significantly broader niche widths compared to top predatory teleost assemblages with a wide and enriched range of δ13C values relative to the local marine community, suggesting that they forage over broad spatial scales along the east coast of southern Africa. Results from the passive acoustic telemetry investigation, conducted over a period between 10 and 22 months, supported these findings showing that the majority of tagged adult sharksexhibited temporally and spatially variable residency patterns interspersed with migration events. Ten individuals undertook coastal migrations that ranged between 433 and 709km (mean = 533km) with eight of these sharks returning to the study site. During migration, individuals exhibited rates of movement between 2 and 59km.d-1 (mean = 17.58km.d-1) and were recorded travelling annual distances of between 450 and 3760km (mean = 1163km). These findings suggest that adult bull sharks are not the sedentary species once thought to be but rather, consistently move over broad spatial scales on the east coast of southern Africa and play an important predatory role shaping and linking ecological processes within the southwest Indian Ocean.

  • Description: HIV/AIDS has rapidly spread globally since its inception more than three decades ago and almost every sort of communication media have been utilised to disseminate information helpful to reduce its spread. This research is based on a case study of Forte FM’s HIV/AIDS campaign programmes in the reduction of the spread of HIV/AIDS in Golf Course and Ntselamanzi areas in Alice, Eastern Cape. To explore and evaluate the effectiveness of Forte FM’s HIV/AIDS programmes, the researcher employed a descriptive qualitative research paradigm whereby convenience and purposive non-probability sampling methods were used to draw samples of participants for focus groups and in-depth interviews. Bearing in mind the total population of Golf Course and Ntselamanzi residential areas, the researcher perceived it applicable to establish two focus groups in each area consisting of at least eight participants in each focus group, making a total of four focus groups for both areas. Additionally, the radio programmes manager was also interviewed for her views. The collected data were analysed thematically to infer the meaning and present the findings. The findings revealed that the station disseminates influential information towards socio-behavioural change in the reduction of the spread of HIV/AIDS in Golf Course and Ntselamanzi. The research participants expressed that the station’s programmes on HIV/AIDS awareness are easily understood and influence their behaviour as they enlighten and educate them about the dangers of HIV/AIDS and how to reduce its spread. Another critical finding of this study as highlighted by the participants is the use of local language in these programmes which listeners view as a contributing element towards the reduction of the spread of this epidemic disease. The findings also showed that the station’s radio programmes have been effective for the fact that the station depends more on two-way participatory communication whereby listeners are involved and participate in the development and running of these programmes.

  • Description: Aquatic weeds transform and degrade the ecosystems which they invade, impacting various aspects of their surroundings ranging from the community level to disrupting important processes affecting ecosystem services. All of the major aquatic weeds of South Africa are found in the Cape Town Metropolitan Area. Landowners, whether private or public, are legally obliged to manage the listed invasive species through applying environmentally acceptable methodologies. This thesis provides an overview of the strategic management options, prevention, early detection, rapid response and eradication of new invasions, and containment and control species of established species. It discusses the different control methods available for managing aquatic weeds, namely mechanical, manual, chemical and biological, and the integration of different methods to improve their effectiveness. Although various studies have shown that biological control is the most cost–effective, environmentally-friendly and sustainable method, it is not yet fully integrated into weed management programmes in South Africa. In addition, the successes achieved in other parts of the world with the control of water hyacinth through biological control have not been repeated in the urban environment, despite the fact that South Africa has the highest number of biological control agents available for the weed. Urbanisation puts pressure on the natural environment and ecosystem functioning. Nutrient-enriched waters support aquatic weed growth and pose a challenge to the management thereof, in particular with regard to integrating biological control into management programmes. The aims of this study were to determine the reasons for the lack of integration of biological control into weed management programmes in South Africa, to determine the feasibility of integrating biological control in aquatic weed management programmes in a complex urban environmental and socio-political landscape by means of three case studies in the Cape Town Metropolitan Area, which showed that biological control is feasible in urban environments and should be considered. Two surveys were conducted to determine the reasons for the lack of integration of biological control into weed management programmes. The surveys showed that there is a gap between research and implementation as a result of poor communication, non-supporting institutional arrangements and a lack of appropriate capacity and skills at the implementation level. Recommendations were offered to address these issues.

  • Description: The purpose of the study has been to assess the question of sustainability of economic growth and human development, particularly using sub-Saharan Africa in context. Sub-Saharan Africa is an interesting case study because, on the one hand, it has been mired in poverty and remains the least developed region in the world, and on the other, it has experienced a revival in economic growth since the mid-1990s. Economists tend to use the term economic development and economic growth interchangeably. However, questions have been raised about whether Africa’s latest growth episode is indeed ‘development’. Although there are many issues at stake, the key question, and the focus of this thesis, is whether sub-Saharan Africa’s revival is sustainable. The paper sets out the debate between the ‘World Bank view’ and the ‘alternative view’. The main debate lies around how genuine development should be achieved. Firstly, the ‘World Bank view’ claims that economic growth is necessary and sufficient condition to achieve development. Economic growth will be generated by ‘orthodox’ policies and this growth will automatically trickle-down and stimulate development. Secondly, the ‘alternative view’ argues that economic growth is necessary but it is not sufficient to stimulate sustainable development. Economic growth without ‘qualitative’ change is not ‘sustainable’. Indeed, human development shortfalls (as well as other, social, political and structural problems), if not addressed through appropriate policy interventions, can undermine economic growth. The ‘alternative view’ appears to be strongly supported by evidence from other developing regions such as Latin America and East Asia. The empirical study conducted in this thesis reinforces doubts about ‘sustainability’. Even though there are signs of convergence in some indicators; this is not the case for all indicators. More importantly the gap between sub-Saharan Africa and other developing regions remains very wide. Sub-Saharan Africa’s development path remains uncertain. The intention in this study is not to be conclusive that sub-Saharan Africa cannot achieve sustainable development. Rather the study attempts to identify potential hindrances to sub-Saharan Africa’s development and to provide a solid foundation for further research in the same direction.

  • Description: While existing literature shows a considerable increase in the numbers of women in academia research on the experiences of women in universities has noted their continued occupation of lower status academic positions in relation to their male counterparts. As the ladder gets higher, the number of women seems to drop. These studies indicate the marginalization of women in academic settings, highlighting the various forms of subtle and overt discrimination and exclusion women face in academic work environments. In this study I ask how academic women in South Africa narrate their experience of being ‘outside in’ the teaching machine. It has been argued that intertwined sexist, patriarchal and phallocentric knowledges and practices in academic institutions produce various forms of discrimination, inequality, oppression and marginalization. Academic women report feeling invisible and retreating to the margins so as to avoid victimization and discrimination. Others have pointed to the tension between the ‘tenure clock’ and the ‘biological clock’ as a source of anxiety among academic women. Where a masculinised presentation of the self is adopted as a solution to this dilemma, the devaluation of the feminine in the academic space is confirmed. However, experiences of academic women are not identical. In the context of studies showing the importance of existing personal and social resources, prior experience and having mentors and role models in the negotiation of inequality and discrimination, I document the narratives of women academics who are the first in their families to graduate with a university degree. These first-generation academic women are therefore least likely to have access to social and cultural resources and prior experiences that can render the academic space more hospitable for the marginalised. Employing Spivak’s deconstruction of the concept of marginalisation as my primary interpretive lens, I explore the way in which, in their narratives, first-generation academic women negotiate marginality. These narratives depict a marginality that might be described, following Spivak, as ‘outside/in’, that is, as complex and involving moments of accommodation and resistance, losses and gains, pain and pride.

  • 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: The use of technology for competitive advantage has become a necessity, not only for corporate organisations, but for higher education institutions (HEIs) as well. Consequently, corporate organisations and HEIs alike must be equipped to protect against the pervasive nature of technology. To do this, they implement controls and undergo audits to ensure these controls are implemented correctly. Although HEIs are a different kind of entity to corporate organisations, HEI information technology (IT) audits are based on the same criteria as those for corporate organisations. The primary aim of this research, therefore, was to develop a set of IT control criteria that are relevant to be tested in IT audits for South African HEIs. The research method used was the Delphi technique. Data was collected, analysed, and used as feedback on which to progress to the next round of data collection. Two lists were obtained: a list of the top IT controls relevant to be tested at any organisation, and a list of the top IT controls relevant to be tested at a South African HEI. Comparison of the two lists shows that although there are some differences in the ranking of criteria used to audit corporate organisations as opposed to HEIs, the final two lists of criteria do not differ significantly. Therefore, it was shown that the same broad IT controls are required to be tested in an IT audit for a South African HEI. However, this research suggests that the risk weighting put on particular IT controls should possibly differ for HEIs, as HEIs face differing IT risks. If further studies can be established which cater for more specific controls, then the combined effect of this study and future ones will be a valuable contribution to knowledge for IT audits in a South African higher education context.

  • Description: This study examines selected works by four white female Zimbabwean writers: Alexandra Fuller, Lauren Liebenberg, Bryony Rheam and Lauren St John, in light of the controversy over the spate of white memoirs which followed the violent confiscation of white farms in Zimbabwe from 2000 onwards. The controversy hinges on the notion that white memoir writers exploit the perceived victimhood of white Zimbabweans in the international sphere, and nostalgically recall a time of belonging – as children in Rhodesia – which fails to address the fraught colonial history which is directly related to the current political climate of the country. I argue that such critiques are too generalised, and I regard the selected texts as primarily critical of the values and lifestyles of white Rhodesians/Zimbabweans. The texts I have selected include a range of autobiographical and fictional writing, or memoirs and pseudo-memoirs, and I focus on form as a medium enabling an exploration of identity. The ways in which these authors conform to and adapt particular narratives of becoming is examined in each chapter, with a particular focus on the transition from innocence to experience, the autobiography, and the Bildungsroman. Gender is a recurring point of interest: in each case the female selves/protagonists are situated in terms of the family, which, in reflecting social values, is a key site of conflict. In regard to trends in white African writing, I explore the white African (farm) childhood memoir and the confessional mode. Ultimately I maintain that while the texts may be classified as white writing, as they are fundamentally concerned with white identity, and therefore evince certain limitations of perspective and form, including clichéd tendencies, all the writers interrogate white identity and the fictional texts more self-reflexively deconstruct tropes of white writing.

  • Description: The 1994 democratic elections heralded a significant change in South Africa‟s political and social landscapes. This historic moment, and the subsequent democratic developmental processes that unfolded aimed at laying the foundations for a democratic state, were the culmination of a long history of struggle by the Black majority, in alliance with other social forces, against colonialism and apartheid. One of the significant social forces that emerged as part of this struggle against racial oppression was the African National Congress Youth League (ANCYL). It is argued that the two most important developments in South African politics during the 1940‟s were the emergence of the African National Congress Youth League and the consolidation of its influence on the ANC leadership. The African National Congress Youth League was formed against the background of very distinct circumstances, the first being the worsening economic conditions for the growing African working class and the declining African peasantry. The second was the inability of the African National Congress to respond to the material challenges confronted by the African majority, because of its leadership and organisational weaknesses. The political programme of the ANCYL was rallied under the ideological auspices of African Nationalism, and its organisational programme under the articulated need to build a mass based and campaigning organisation. With a very strong leadership, the ANCYL was able to, within five years, assert its leadership and authority in the ANC with key elements of its manifesto forming significant parts of the ANC Programme. This culminated into the rise of the generational theme of the ANC Youth League of “Freedom in our Lifetime”. Essentially freedom was conceived as the abolishment of formal apartheid, and the delivery of a democratic South Africa. Formal democracy became a reality in South Africa in 1994 and at the helm of the ANC and the new government was the ANC Youth League generation of the 1940‟s. This generation had over fifty years struggled for freedom and 1994 represented the formal victory over apartheid and the attainment of a generational mission. The ushering in of formal democracy in 1994 heightened the expectations of the black majority in terms of its elevation from a point of view of its existing socio-economic realities. Close to twenty years after the end of formal apartheid the reality has been less than satisfactory in terms of addressing these socio-economic realities. What has been observed on the contrary is an increase in key measures such inequality and unemployment. Subsequent to that has been a less than satisfactory performance in the area of economic transformation which has been seen as a critical limiting factor in addressing the legacies of apartheid, particularly among the black majority. These limits to transformation have resulted in discontentment among the majority, claiming that democracy has not yielded to any significant changes in their material lives. The discontentment has been particularly proliferated among the youth, who bear the brunt of social challenges such as unemployment. The ANC Youth League, has had to confront the reality of being of a youth league of a governing party and balancing that with the social discontentment that has developed among South African, particularly the youth, as a result of perceived lack of social transformation. In balancing these two realities, the ANC Youth League has found itself at the centre of South African politics similarly to the 1940s generation of ANC Youth League leaders of the Youth League who had been mobilised under the theme of “Freedom in our Lifetime”. The contradictions within the ANC, of which the ANC Youth League has found itself at the centre of, and the need to become a socially relevant political force have culminated into the birth of a generational theme led by the ANC Youth League of “Economic Freedom in our Lifetime”.

  • Description: The Cancer Stem Cell (CSC) theory suggests that cancers arise from and are maintained by a subpopulation of cancer cells with stem cell properties. Molecular chaperones are key components of cellular regulation. The overexpression of chaperones has become synonymous with cancer cells with chaperones being recognized as bona fide anti-cancer drug targets. Although chaperone activity has been characterized in cancer cells, very little is known about the cellular functions of chaperones in cancer stem cells. We set out to compare the expression of selected molecular chaperones in non-stem cancer cell and cancer stem cell enriched populations isolated from breast cancer lines, in order to identify chaperones differentially expressed between the two populations for further biological characterization. In order to isolate breast cancer stem cells from the MCF-7 and MDA-MB-231 breast cancer cell lines, three cancer stem cell isolation and identification techniques were utilized based on (1) cell surface marker expression (CD44+/CD24- and CD44+/CD24-/EpCAM+ phenotypes), (2) aldehyde dehydrogenase enzyme activity (ALDHHi) and (3) ability to grow in anchorage-independent conditions. The MDA-MB-231 and MCF-7 breast cancer cell lines displayed CD44+/CD24- cell populations with the MCF-7 cell line additionally displaying a large CD44+/CD24-/EpCAM+ population. Although both cell lines showed similar ALDHHi populations, they differed substantially with respect to anchorage-independent growth. MCF-7 cells were able to form anchorage-independent colonies while the MDA-MB-231 cell line was not. Anchorage-independent MCF-7 cells showed enrichment in CD44+/CD24- and CD44+/CD24-/EpCAM+ cells compared to adherent MCF-7 cells, and were selected for gene expression studies. Gene expression studies identified 22 genes as being down-regulated at the mRNA level in the anchorage-independent MCF-7 cells, while only 2 genes (BAG1 and DNAJC12) were up-regulated. The down-regulation of selected chaperones in anchorage independent MCF-7 cells was confirmed at the protein level for selected chaperones, including DNAJB6, a type II DNAJ protein shown to be involved in the regulation of Wnt signaling. In order to characterize the effect of DNAJB6 expression on BCSCs we developed a pCMV mammalian expression plasmid for both DNAJB6 isoforms (DNAJB6L and DNAJB6S). We successfully constructed mutants of the conserved histidine-proline-aspartic acid (HPD) motif of the J domain of DNAJB6S and DNAJB6L. These constructs will allow the analysis of the role of DNAJB6 in cancer stem cell function. To the best of our knowledge, this is the first report to focus on the comparative expression of molecular chaperones in normal and cancer stem cell enriched breast cancer populations.

  • Description: Die Eden- en Overbergdistrik in die Suid-Kaap vorm die mees suidelike substreke van die winterreëngebied. Dit is geleë tussen 33° 45‟ en 34° 50‟ suiderbreedte en tussen 19° 0‟ en 23° 45‟ oosterlengte. Die westelike grens van die substreek word gevorm deur die Villiersdorp-Botrivier-gebied. Aan die noordekant word die substreek begrens deur die Sonderend-, Lange- en Outeniquabergreekse. Die oostelike grens word gevorm deur die Bloukransrivier. Die Indiese Oseaankuslyn vanaf Nature‟s Valley in die ooste tot by Kleinmond in die weste vorm die suidelike grens. In die Suidkusstreek word 54.5% van die Wes-Kaapse melkproduksie en 24% van Suid-Afrika se melkproduksie deur 1900 melkprodusente geproduseer (Dowrey 2005). Ses en dertig persent van die bruto jaarlikse veeproduk is afkomstig vanaf suiwelprodukte wat hoofsaaklik vanaf aangeplante weiding geproduseer word. Aangeplante weiding beslaan 37.7% van die totale oppervlakte van die vee- en saaigebiede van die Suidkusstreek (Botha 2003). Weens beperkte, skaars besproeiingswater in groot dele van die Suid-Kaap, word heelwat weiding slegs aanvullend besproei (Protopapas 2004). Voervloeiprogramme vir melkproduksie onder aanvullende besproeiing bestaan hoofsaaklik uit kikoejoe (Pennisetum clandestinum) en lusern (Medicago sativa) (Botha 2003). Die droëmateriaalproduksie en weikapasiteit van lusern volg, soos kikoejoe, „n baie sterk seisoenale tendens met „n piek in die somer / herfs en „n laagtepunt in die winter (Durand 1993; Botha 1998; Botha 2003). Voervloeiprogramme met lusern of kikoejoe as hoofkomponente het gewoonlik voertekorte gedurende die winter tot gevolg. Hoofsaaklik om dié rede het boere uit die lusernproduserende gebiede van Heidelberg, Riversdal, Herbertsdale en Mosselbaai, deur hul onderskeie boereverenigings, „n versoek aan Outeniqua Navorsingsplaas gerig om ondersoek in te stel na moontlike oorsaaipraktyke wat die droëmateriaalproduksie van lusernstelsels gedurende die winter kan verhoog. Kikoejoeweiding word reeds die afgelope aantal jare suksesvol met Westerworldsraaigrasse oorgesaai vir beter herfs-, winter- en lenteproduksie. Anders as by kikoejoeweidings bestaan daar huidiglik geen beproefde oorsaaipraktyke wat die produksiepotensiaal van lusern in die winter en vroeë lente kan verhoog nie (Anoniem 2002).
