- Description: This study constitutes an inquiry into how Olive Schreiner‟s peripheral position as a colonial woman writer enabled her rewriting of feminine identity, specifically her subversion of Victorian feminine stereotypes. I focus particular attention on three novels: The Story of an African Farm (1890), and the posthumously published From Man to Man (1926) and Undine (1929). I employ a feminist literary approach to examine how Schreiner‟s hybrid identity as a British South African enabled her revisioning of femininity. If Schreiner is situated within the context of her time, it can be demonstrated that her negotiations of feminine identity are influenced by her dual intellectual and cultural heritage. On the one hand, she can be situated within a British tradition of women‟s writing – in particular, the New Woman fiction which emerged in the late nineteenth century. On the other hand, she can be situated within a nascent South African literary tradition – and demonstrates prototypically post-colonial concerns. Schreiner‟s writing style develops out of her colonial heritage and her experiences as a woman living in a patriarchal society. The resultant voice subverts the narrative traditions of the metropolitan novel in an attempt to articulate an alternative view of femininity. I examine in detail how Schreiner undermines and subverts Victorian stereotypes, and focus particular attention on the „fallen woman‟ and the „mother-figure‟. She attempts to challenge conventional Victorian conceptions of femininity by erasing the binary between the „angel‟ and the „whore‟ in order to create a New Woman. In Undine and The Story of an African Farm the full realisation of this New Woman is deferred, since both protagonists die, but From Man to Man is more nuanced, particularly in its emphasis on economic empowerment for women. Schreiner also destabilises traditional notions of motherhood, in order to offer glimpses of an alternative maternal role. It is my contention that, in her depiction of mother-figures and (un)fallen women, Schreiner challenges stock Victorian notions of femininity and, in the process, creates a space in which new possibilities for women can be imagined and negotiated.

- Description: The study reviews the political transition after the first decade of democracy from the trade union leaders’ perspectives. It seeks to understand whether trade union leaders see workers as having reaped benefits from their struggles. Interviews were conducted with ten current and past trade union leaders on their perceptions about the political transition. The trade union leaders that were interviewed have rich experience of combining their organisational and mobilising strength with strategies of engagement. Their involvement with trade unions can be traced back during the dark years of Apartheid. Some of them are still active members of trade unions who are deeply involved in policy formulation at national level. Others occupy influential positions in the private and public sectors. The study investigates and analyses the labour movement’s objectives, strategies and struggles from the apartheid, transition, and democratic eras and into the future. It looks at how these objectives were achieved and how the strategies were implemented. The study revealed that progress was made in the political sphere, e.g. a parliamentary office was established to ensure that workers have a voice in parliament. The study found clear evidence of influence by the labour movement in economic and labour legislation through structures like NEDLAC. In the economic arena, the study found that workers’ economic expectations were partially fulfilled. Trade union leaders attributed this to the failure of the government’s GEAR policy to create jobs. They insisted that RDP should be implemented. The study revealed evidence of serious tensions within the ANC/COSATU/SACP Alliance. The study found that the influence of the labour ally, COSATU, in the Tripartite Alliance had been curtailed. The study also found that the strength of the labour movement eroded during the first decade of democracy. The research found that the labour movement took new initiatives such as union investment companies. The research also found support for the theory that COSATU’s obsession with alliance politics was a barrier to labour unity. COSATU was not involved in the merger talks between FEDUSA and NACTU. The respondents generally felt positively about the future prospects. Respondents were mostly optimistic about the political transformation. If there was slow delivery or no delivery by the government or business, the unions vowed to take to the streets.

- Description: The study focuses on Lesotho‟s Public Service. The aims of this study were to examine the factors that led to the repeal of the Public Service Act No.13 of 1995. This study looks at the legislative constraints and attitudes of civil servants towards unionisation in the Public Service. It also outlines the relevant provisions of the Public Service Act No.1 of 2005; the changes that have occurred since its inception. Findings show that the Public Service Act No.13 of 1995 was repealed in order to reform the Public Service. The Ministry of the Public Service implemented five-year strategic plans to reform the public service. Changes have occurred in the public service since the inception of the 2005 Act; however, they differ from ministry to ministry. The respondents included public officers from the Ministry of the Public Service, Ministry of Justice, Law Office, Ministry of Employment and Labour, Ministry of Planning, the Ombudsman Office, Parliament, different ministries, the International Labour Organisation (ILO), the Congress of the Lesotho Trade Unions (COLETU) and the Lesotho Public Service Staff Association (LEPSSA).

- Description: This study investigates the role played by the Namibia National Teachers’ Union (NANTU) in school management. It examines the challenges faced by school principals in managing schools as a result of the presence of unions. In order to understand the behaviour and impact of union representatives in schools the study makes use of literature on teacher unionism, democratic, political and ambiguity management and leadership theories. Working in the interpretive orientation the study used semi-structured interviews, document analysis and focus group discussions. The research was conducted in the form of a case study involving three schools in the Kavango region of Namibia, and the data collected were dealt with according to case study principles. The study reveals that the presence of the union has several benefits for the school: for example, it advances the democratic participation of stakeholders, provides feedback to the school principal on how staff members experience his or her leadership, and offers advice on labour-related matters. It was also discovered that NANTU representatives act as mediators in conflict situations, which means that teachers can become better at managing and resolving conflict through their experience of serving on the union structures. However it was also discovered that the presence of NANTU in schools has several negative effects on schooling. For example, NANTU activities can disrupt school programmes; moreover, in some schools, neither NANTU representatives nor school principals understand their own or each other’s roles, and consequently they are always in conflict. The absence of a policy regulating the representation of NANTU in decision-making structures in schools causes the conflict to escalate. It emerged that the role of NANTU in schools is mainly determined by the leadership style of the school principal and the effectiveness of the NANTU representatives in that particular school. For example, an autocratic leadership style on the part of the school principal tends to exacerbate the conflict situation, while NANTU has been known to mobilize learners to demand the removal of school principals through class boycotts. NANTU is more concerned with defending the rights and interests of its members than any other matter affecting education. This research is likely to benefit school managers, policy makers and implementers, and NANTU structures, as it provides clarity on what both NANTU and school principals expect from one another. The study also demonstrates that school principals need to acknowledge and consider the divergent nature of the various interest groups in schools.

Using local experts as benchmarks for household local ecological knowledge: scoring in South African savannas

- Description: It is well recognised that local ecological knowledge is an important facet of natural resource management in rural regions of the developing world. However, techniques to assess levels and to integrate it into formal or informal management approaches require further development. In particular, quantitative tools are missing, which would allow more robust analysis of the factors that positively or negatively affect local ecological knowledge and vice versa. This paper reports on a quick assessment approach that provides a quantitative score of generalist local ecological knowledge at the household level. It does so by comparing responses to the knowledge of local people identified as experts within the community. In this way it is both locally constructed and contextualized, and thereby avoids pitfalls of trying to score local ecological knowledge relative to conventional scientific knowledge which frequently cannot account for local constructs. The approach is applied at eight villages throughout the savanna biome in South Africa.

- Description: This article highlights the emerging literature on therapist responsiveness in psychotherapy and examines several concepts used to identify dimensions of responsiveness. Some methodological obstacles are identified to studying responsiveness in a systematic manner, and several examples of existing responsiveness research are reviewed. It is argued that meaningful theory on responsiveness has emerged from research methods that are qualitative and interpretive and that the writing of systematic case studies can be of particular importance since only the presentation of a case unfolding over time can disclose some of the more complex aspects of therapist responsiveness. Examination of a series of systematic case studies of the treatment of post traumatic case disorder in South Africa was used to derive a model for guiding therapist responsiveness with respect with what to focus on at a particular phase of the therapy within a particular session. Material from the cases is used to illustrate aspects of the model related to building social support for the client and promoting emotional processing of trauma memories. , Acknowledgements: This research was supported by grants from the National Research Foundation and the Joint Research Committee of Rhodes University.

- Description: An ethnobotanical survey of plants used for the treatment of eye infections was carried out in the Eastern Cape Province of South Africa. The study revealed that 12 plant species are commonly used with Hippobromus pauciflorus (L.f) Radlk being the most frequent. The crude extracts of the leaves, stem bark and roots of the plant were investigated for antimicrobial activity against 10 bacterial and four fungal strains. The methanol extracts of the plant parts were the most active and showed appreciable activity against Gram-positive and Gram-negative bacteria. The methanol extracts of the leaves and stem bark inhibited the growth of fungi with activities ranging from 78.70 percent to 100 percent on Aspergillus niger and Penicillium notatum. The acetone extracts of the leaves and stem bark were active against A. niger (51.76 percent) and P. notatum (77.22 percent). The aqueous extract of Hippobromus pauciflorus leaves at 50, 100 and 200 mg/kg body weight doses were evaluated for anti-inflammatory, analgesic and antipyretic activities in male Wistar rats. Anti-inflammatory activity was studied by using carrageenan-and histamine induced oedema right hind paw volume while the analgesic effect was evaluated using formalin-induced pain and tail flick nociception response. The brewer’s yeast-induced pyrexia model was used for the antipyretic investigation. The extract at all the doses used significantly inhibited both the carrageenan- and histamine-induced inflammation in a manner that was not dose dependent. The extract reduced the formalin-induced pain licking as well as prolonged the reaction time in the tail flick-induced pain. The effects of the aqueous extract of the plant leaves at 50, 100 and 200 mg/kg body weight doses were investigated for 14 days on some biochemical parameters of male Wistar rats. The extract at all the doses tested did not significantly alter the levels of white blood cells, red blood cells, mean corpuscular volume, platelets, neutrophils, monocytes, lymphocytes and large unstained cells. While the levels of haemoglobin, packed cell volume and basophils increased at specific doses, those of mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration and eosinophils decreased. In vitro antiviral activities of the plant against herpes simplex virus type 1(HSV-1) and coxsakie virus B6 were investigated. Cytotoxicity was evaluated by MTT assay in Vero cells. At concentrations ranging from 165-270/μg/ml there was significant antiviral activity against HSV-1, but toxicity was also noted. There was no antiviral activity against coxsakie virus B6. Bioactivity-guided fractionation of the leaves of H. pauciflorus yielded three known compounds. From the ethyl acetate fraction, two compounds were isolated (epicatechin and -sitosterol ) and from the n- hexane fractions, one compound (lupeol) was isolated. They were isolated and identified using various techniques. The antimicrobial, anti-inflammatory, analgesic and anti-pyretic activity of these compounds have been reported in literature. The structure and distribution of foliar appendages on the leaves of H. pauciflorus were examined by scanning electron microscope. The leaves have long unicellular nonglandular trichomes which were distributed over the mid rib and densely populated at the edges of the adaxial and abaxial surfaces. In general, the experiments and tests conducted in this study appear to have justified the use of Hippobromus pauciflorus for the treatment of eye infections and make a substantial contribution to the knowledge base of the use of herbal medicine for the treatment of the eye infections.

- Description: The ionosphere is an important factor in high frequency (HF) radio propagation providing an opportunity to study ionospheric variability as well as the space weather conditions under which HF communication can take place. This thesis presents the validation of HF propagation conditions for the Ionospheric Communication Enhanced Profile Analysis and Circuit (ICEPAC) and Advanced Stand Alone Prediction System (ASAPS) models over Africa by comparing predictions with the measured data obtained from the International Beacon Project (IBP). Since these models were not developed using information on the African region, a more accurate HF propagation prediction tool is required. Two IBP transmitter stations are considered, Ruaraka, Kenya (1.24°S, 36.88°E) and Pretoria, South Africa (25.45°S, 28.10°E) with one beacon receiver station located in Hermanus, South Africa (34.27°S, 19.l2°E). The potential of these models in terms of HF propagation conditions is illustrated. An attempt to draw conclusions for future improvement of the models is also presented. Results show a low prediction accuracy for both ICEPAC and ASAPS models, although ICEPAC provided more accurate predictions for daily HF propagation conditions. This thesis suggests that the development of a new HF propagation prediction tool for the African region or the modification of one of the existing models to accommodate the African region, taking into account the importance of the African ionospheric region, should be considered as an option to ensure more accurate HF Propagation predictions over this region.

- Description: The ionosphere is an important factor in high frequency (HF) radio propagation providing an opportunity to study ionospheric variability as well as the space weather conditions under which HF communication can take place. This thesis presents the validation of HF propagation conditions for the Ionospheric Communication Enhanced Profile Analysis and Circuit (ICEPAC) and Advanced Stand Alone Prediction System (ASAPS) models over Africa by comparing predictions with the measured data obtained from the International Beacon Project (IBP). Since these models were not developed using information on the African region, a more accurate HF propagation prediction tool is required. Two IBP transmitter stations are considered, Ruaraka, Kenya (1.24°S, 36.88°E) and Pretoria, South Africa (25.45°S, 28.10°E) with one beacon receiver station located in Hermanus, South Africa (34.27°S, 19.l2°E).

- Description: The study aims to determine the contribution made by available ram growth- and breed standard parameters on the sale price of auctioned rams in Namibia. These findings serve as an indication of the importance ram buyers place on individual parameters in selecting rams for breeding purposes. It furthermore tries to establish whether scientific measurement for the estimation of ram breeding values takes precedence over subjective appraisal. The analysis of the 100 day and 270 day growth performance of the progeny of selected Veldram tested rams were used to evaluate the accuracy of the estimation of ram breeding values and may serve to validate the proper execution of these Veldram tests.

- Description: Vision based technology such as motion detection has long been limited to the domain of powerful processor intensive systems such as desktop PCs and specialist hardware solutions. With the advent of much faster mobile phone processors and memory, a plethora of feature rich software and hardware is being deployed onto the mobile platform, most notably onto high powered devices called smart phones. Interaction interfaces such as touchscreens allow for improved usability but obscure the phone’s screen. Since the majority of smart phones are equipped with cameras, it has become feasible to combine their powerful processors, large memory capacity and the camera to support new ways of interacting with the phone which do not obscure the screen. However, it is not clear whether or not these processor intensive visual interactions can in fact be run at an acceptable speed on current mobile handsets or whether they will offer the user a better experience than the current number pad and direction keys present on the majority of mobile phones. A vision based finger interaction technique is proposed which uses the back of device camera to track the user’s finger. This allows the user to interact with the mobile phone with mouse based movements, gestures and steering based interactions. A simple colour thresholding algorithm was implemented in Java, Python and C++. Various benchmarks and tests conducted on a Nokia N95 smart phone revealed that on current hardware and with current programming environments only native C++ yields results plausible for real time interactions (a key requirement for vision based interactions). It is also shown that different lighting levels and background environments affects the accuracy of the system with background and finger contrast playing a large role. Finally a user study was conducted to ascertain the overall user’s satisfaction between keypad interactions and the finger interaction techniques concluding that the new finger interaction technique is well suited to steering based interactions and in time, mouse style movements. Simple navigation is better suited to the directional keypad.

- Description: The volatility of stock markets has important implications for investment decision making, financial stability and overall macroeconomic stability. This study examines the risk-return relationship as well as the behaviour of volatility of the South African equity markets using both aggregate, industrial level and sector level data. The study is divided into three parts. The first part investigates the behaviour of volatility in each of the industries, sectors and the benchmark series focussing on whether volatility is symmetric or asymmetric. Subsequently we investigate which, among the GARCH family of models appropriately captured the riskreturn relationship under which distributional assumption. The second part examines the riskreturn relationship on the SA stock market. The third part examines the long term trend of volatility and whether volatility significantly increases during financial crises and during major global shocks. The GARCH-M, EGARCH-M and TARCH-M models under the Gaussian, Student –t and the GED are used. The findings this study makes are as follows: firstly, there is no clear relationship between risk and return. Secondly, volatility is asymmetrical, implying that bad news has a greater effect on volatility than good news in the South African equity market. Thirdly, the TARCH-M model under the GED was found to be the most appropriate model. Fourthly, volatility increases during financial crises and major global shocks. Overall, volatility is generally not priced on the South African equity markets. Thus, both local and international investors need to consider other factors that influence returns such as skewness. The general increase in volatility during financial crises and major global shocks poses a major concern for policy makers as this may cause financial instability. Thus policy makers need to be mindful of the behaviour of volatility in the South African equity market in response to external shocks.

Through it they reveal the context in which alien plants have become an urgent affair of the state. Following their lead, I show how alien plants (particularly Australian wattle) continue to provide grounds for new social and political aspirations in South Africa, though in a different setting. With reference to a group of private landowners on the fringe of a World Heritage Site -- the Baviaanskloof Mega-Reserve, Eastern Cape, South Africa -- I show how an increasingly apocalyptic and xenophobic environmental agenda has influenced local activists seeking to address social and ecological issues in tandem with alien-eradication. These local activists adhere to a particular brand of environmentalism which Milton (1993) argues can be considered a social, cultural and religious phenomenon. The subjects of my main empirical investigation offer practical ways of achieving a transformational end through a new ritual activity in relation to a spread and exchange of environmental ideas and practices on a world-wide scale. On the ground this group practices ecosocietal restoration through which they aspire to mend the bond between people and the land in a spiritual and moral sense, bolstering intrinsic incentives for environmental stewardship and achieving ―cultural reconciliation in an attempt to reimagine what South Africa could be.

- Description: Over the past decade, scholars from various fields have increasingly emphasized the detrimental effects of global socioeconomic processes on biodiversity. The industrial revolution, the demographic explosion of Homo sapiens, and the rise of the global exchange economy are all implicated as major factors that influence the loss of species diversity. From the late 1980s onward, biosystematics and conservation biology have successfully brought this concern to the attention of the public. Biodiversity is increasingly recognized as an essential resource on which families, communities, and nations depend. Biologists, ecologists, and conservationists have further recognized that solutions to biological problems lie in the mechanisms of social, cultural, and economic systems, which has led to attempts to place a monetary value on species and ecosystems to calculate the cost of using and conserving biodiversity.

- Description: The thesis “When birthing makes the news: the depiction of women as a newsworthy item in Die Burger (Oos-Kaap)” analyses a common, yet complex news topic in the South African print media due to the sensitive, often sensationalised, nature of the topic. The private experience of birthing is featured more and more in the public domain of newspapers because of widespread service delivery problems within the South African health department. Focussing on the Eastern Cape, I examine the representation of birthing in Die Burger (Oos-Kaap) in texts printed between 2005 and 2007, and scrutinise the media’s monitorial role of a self-appointed public hero acting on behalf of the women, to expose the poor conditions at government hospitals, specifically in the Nelson Mandela Bay region. How the women and their bodies are reported on, creates a discursive tension between the negative portrayals of the birthing women and the monitorial role of the media. The news values of sensationalism and profit are achieved with visceral representations of the reproductive functions of the birthing women. A poststructuralist feminist theoretical framework reveals discourses that perpetuate race, class and gender inequalities in the apparently socially-concerned sample of texts. A Critical discourse analysis (CDA) provides an approach and method to inform a close textual analysis of both the lexical and visual elements of the texts. The discourses in the sample differed from text to text. Despite these differences, the monitorial role of the media is still achieved. My research argues that acting in the public interest with sensationalist copy is still acting in the public interest. I conclude that it is not easy for newspapers to separate sensationalism from accountability. Media practitioners should be aware of their role in constructing women’s identities and be particularly thoughtful when reporting on birthing. In doing so, this research aims to improve the manner in which women and their bodies are reported on within the news industry.

- Description: White rhino populations did not occur historically in the Eastern Cape, South Africa (Skead 2007). They have, however, been introduced into a number of reserves within the Eastern Cape for reasons such as conservation, ecotourism and hunting. Based on the literature on the species, it was hypothesized that white rhinoceros would have been introduced in grass-rich habitats, as they are bulk grazers. White rhinoceros populations were further assessed in terms of population establishment by outlining their distribution and performance since introductions and this was done by extracting intercalving intervals from the literature of native populations and comparing such to the Eastern Cape intercalving intervals, extracted from data obtained from landowners. Finally, the diet of white rhinoceros was quantified, in order to identify plant species potentially at risk from white rhino herbivory using Shamwari Private Game Reserve as a study site. The distribution of white rhino in the Eastern Cape varies in terms of habitat and vegetation types. The majority (62%) of white rhino are located in grass-poor habitats and are primarily there for ecotourism purposes with only a small percentage kept for conservation purposes in the state reserves. Limited data for intercalving intervals of the white rhino in Eastern Cape are comparable to those of populations in the natural range. The ex situ conservation of white rhino in the Eastern Cape proved to be a success as population numbers have increased markedly since the first survey was conducted (Buijs 1999). The diet section of this study showed that white rhino are highly selective grazers even in a grass-limiting habitat which is dominated by browse. Twenty-five principal dietary items were identified in their diet, with only six being preferred in autumn. These are thus the plant species that could be the most vulnerable to white rhino herbivory. Supplementary food provision plays a big part of the feeding scheme of white rhino in Shamwari Private Game Reserve during the winter season, revealing the little confidence that the management has on natural resource availability to the animals at this time. These findings support the value of the Eastern Cape for ex situ conservation of white rhino, and highlight plant species potentially at risk. There is a need for further research on the population performance of these animals, and the plants identified here need to be monitored to assess white rhino impact on the vegetation
