- Description: Talhado Fishing Enterprises (Pty) Ltd is a squid fishing company founded in 1988, with sea and land based freezing facilities. Operating from the East coast situated in the Port Elizabeth harbour, the company processes and packages its caught and bought out product for sales to its export customers situated in Spain and Italy. The company is privately owned, 38.8 percent owned by previously disadvantaged persons. This study examines the whether it would be feasible to expand its operations into the USA, namely into the California area where a squid fishery exists. The study further centres around the company’s existing markets, namely Spain and Italy, to establish whether demand exists to purchase this Californian squid specie. The reason for the study is that due to legislative and political issues growth in the squid industry in South Africa is limited. It is therefore considered pertinent to source further supply of product in order to expand its business. The aim of the study is establish whether it is feasible to expand the company’s operations internationally and does the outcome of this initial study warrant the development of an in depth business plan. In order to achieve these objectives the following approach was followed: A comprehensive literature study was conducted with regard to the industry internationally and locally; Interviews was conducted with independent experts such as attorneys and industry role players situated in California; Potential sellers of businesses were sourced in the California and interviews were arranged with these role players; The response to the interviews was measured against the literature study conducted and financial statements supplied.

- Description: The purpose of this thesis was to develop a method by which economic value can be imputed from an economic activity to a non-market ecological function or service which contributes to that economic activity. The Knysna River in South Africa was chosen as the ecological function which supported three economic activities from which value was to be imputed; these were the Knysna Municipal Water Supply, Fish Production in the Knysna Estuary and Production of Indigenous Forest within the Knysna Catchment. Three underlying assumptions and two functional operations were required in order to implement the suggested method. The underlying assumptions were: - The ecological and economic activities considered are within a single catchment. - The allocation of value imputed for a specific economic activity to the ecological function or service under consideration (in this case the Knysna River) is proportional to the total contribution of ecological functions or services contributed to the economic activity. - The valuation of the economic activity for the purposes of obtaining a price-quantity point on a demand function is to be full cost pricing with no producer surplus. The two functional requirements were: - Diagram or map the linkages between an economic activity and the supporting ecological functions. - Determine the consumer surplus related to an incremental change in quantity under a demand function where the original price and quantity are known. A value from each of the economic activities was imputed to the Knysna River. However, the method was not tested. Nonetheless applying the equations and collecting the required data allowed several methodological needs to be clearly pointed out. The most acute deficiency was difficulty in obtaining secondary data from governmental agencies, commercial representatives and existing published academic research to ensure a robust price. Also, scientific information was not sufficiently available for allocating ecological contributions to the economic activities. Even with the shortage of credible data the method appears to allow non-market ecological functions to be valued in context of an existing economic system.

An analysis of the efficiency of ontology and symbolic learning algorithms in indigenous knowledge representation

- 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.

- 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: 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: Two possible variables of the McKenzie/Stoughton blanching assay, namely amount applied to the test site and occlusion time have been investigated. Subsequently, two topical steroid preparations, Synalar cream (0,025% fluocinolone acetonide) and Betnovate cream (0,1% betamethasone 17- valerate) were extemporaneously diluted with five and six placebo bases respectively. Taking cognizance of the two possible variables, these diluted preparations were assessed in vivo using a modified version of the McKenzie/Stoughton blanching assay for blanching activity over a 14 month period. It was found that the base E45, which is slightly alkali, had the greatest effect on both preparations. In the case of betamethasone 17-valerate this base caused the conversion to the less active isomer, betamethasone 21-valerate whereas at the end of the 14 month test period it was found that the Synalar/E45 dilution contained no fluocinolone acetonide. Quantitative analysis of all the diluted preparations by high performance liquid chromatography using a reverse-phase system was performed. The data obtained from the systematic studies of the effects of varying concentrations and occlusion times were presented at the Eleventh National Congress of the South African Pharmacological Society

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

- 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.

- 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: Changes in chlorophyll content, carotenoid content and composition, abscisic acid and phaseic acid levels, hydrolytic enzyme activity and polypeptide pattern were monitored during senescence of the primary attached leaves of Hordeum vulgare L. cv. Dyan. Senescence occurred due to the normal course of leaf development or was induced by incubation of leaves in darkness. Loss of chlorophyll and total leaf protein was retarded in light whereas it continued rapidly in leaves from dark-incubated seedlings. Chlorophyll alb ratio increased with the progression of senescence, suggesting that chlorophyll b was referentially degraded during this process. Loss of total protein coincided with enhanced activity of acid and neutral proteases. In contrast, loss of chlorophyll was not accompanied by an increase in· peroxidase activity, suggesting that this enzyme was not responsible for initiating chlorophyll breakdown. Carotenoid and abscisic acid levels were monitored in the same tissue extracts. The results obtained show that the increase in endogenous levels of abscisic acid, induced by senescence, correlated with enhanced epoxidation of the xanthophyll cycle, ie., increased conversion of zeaxanthin to antheraxanthin and all-trans-violaxanthin. In addition, an increase in abscisic acid levels occurred concomitant with a decrease in all-trans-violaxanthin and 9'-cis-neoxanthin, suggesting an apparent 1:1 relationship on a molar basis. It is therefore proposed that enhanced abscisic acid production, due to foliar senescence, arises from fluctuations in carotenoid turnover. Polypeptide patterns in isolated chloroplasts, purified thylakoid and stromal fractions were very similar for leaves incubated in either light or darkness. A decrease in intensity of bands was observed in isolated chloroplasts and stromal fractions. Intensity of bands in thylakoids remained unchanged with the progression of senescence. Protein standards of peroxidase and lipoxygenase co-migrated with proteins of the isolated chloroplast. Although tentative, some proteins of the chloroplast may be representative of precursors of hydrolytic enzymes which are known to increase during senescence.

- Description: The success of C₄ plants lies in their ability to concentrate CO₂ at the site of Rubisco thereby conferring greater efficiencies of light, water and nitrogen. Such characteristics should advantage C₄ plants in arid, hot environments. However, not all C₄ subtypes are drought tolerant. The relative abundance of NADP-ME species declines with increasing aridity. Furthermore, selected species have been demonstrated as being susceptible to severe drought showing metabolic limitations of photosynthesis. However there is a lack of phylogenetic control with many of these studies. The aims of this study were to determine whether the NADP-ME subtype was inherently susceptible to drought by comparing six closely related C₃ and C₄ (NADP-ME) Panicoid grasses. Gas exchange measurements were made during a natural rainless period and a controlled drought / rewatering event. Prior to water stress, the C₄ species had higher assimilation rates (A), and water use efficiencies (WUE[subscript leaf]) than the C₃ species, while transpiration rates (E) and stomatal conductances (g[subscript s]) were similar. At low soil water content, the C₃ species reduced gs by a greater extent than the C₄ species, which maintained higher E during the driest periods. The C₄ species showed proportionally greater reductions in A than the C₃ species and hence lost their WUE[subscript leaf] and photosynthetic advantage. CO₂ response curves showed that metabolic limitation was responsible for a greater decrease in A in the C₄ type than the C₃ type during progressive drought. Upon re-watering, photosynthetic recovery was quicker in the C species than the C₄ species. Results from whole plant measurements showed that the C₄ type had a significant whole plant water use efficiency advantage over the C₃ type under well-watered conditions that was lost during severe drought due to a greater loss of leaf area through leaf mortality rather than reductions in plant level transpiration rates. The C₃ type had xylem characteristics that enhanced water-conducting efficiency, but made them vulnerable to drought. This is in contrast to the safer xylem qualities of the C₄ type, which permitted the endurance of more negative leaf water potentials than the C₃ type during low soil water content. Thus, the vulnerability of photosynthesis to severe drought in NADP-ME species potentially explains why NADP-ME species abundance around the world decreases with decreasing rainfall.

- 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: 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 management of coastal resources in South Africa has come under review as a result of the degradation of environmental resources along the coast. The challenge being faced by resource managers is to achieve economic growth while sustaining South Africa’s coastal resource base (Nobel, 2000). The South African government (RSA, 2000) has developed a coastal management strategy to meet this challenge: The strategy involves the inclusion of all stakeholders in the formation of policy regarding the management of coastal resources, in a more integrated approach to coastal management. To effectively achieve this stakeholder inclusion, it has become necessary to decentralize the political, administrative and fiscal authority to conduct coastal management functions. With regard to the need for fiscal decentralisation this thesis considers the possibility of implementing localised environmental surcharges to finance coastal management initiatives. The ability of the White Paper for Sustainable Coastal Development (RSA, 2000) to provide theformal institutional structure necessary for the introduction of environmental surcharges is firstconsidered. It is shown that the decentralised management strategy has the potential to create a management style that is transparent and accountability orientated. In addition to this the style is capable of adapting to dynamic local coastal conditions and is therefore an appropriate direction in which to steer coastal management in South Africa. The effectiveness of coastal co-management as an informal institutional arrangement is then examined. Provided that local Coastal Management Fora are created to include all relevant stakeholders and that a source of long term financing is secured co-management has the potential to create the conditions necessary for effective coastal management. With regard to a source of long term financing, local environmental surcharges to finance coastal management initiatives are considered. The public’s willingness to contribute to such a surcharge is analysed in the context of Plettenberg Bay by probing their willingness to pay (WTP) for a Bay Management Plan. A survey instrument is developed to measure the public’s WTP. The design of the instrument is based on the Contingent Valuation (CV) method that is used to analyse the nonmarket benefits that environmental resources (such as Plettenberg Bay) provide the public. It is found that the resident population is willing to pay R15 per month toward a Bay Management Plan whilst domestic and foreign tourists respectively are willing to pay R6 and R22 daily. The aggregation of these WTP estimates yields a total passive use value of between R15 397 900 – R20330 500 annually. This nuclear value of the Bay should be included in the formation of local coastal management policy and provides guidance for the introduction of a local environmental surcharge. A budget for a Bay Management Plan is proposed and a progressive surcharge based on municipal property value is set. To finance the local residents’ share of the budget, a monthly surcharge of R1 would be required of the average valued property. To calculate the domestic and foreign tourist contribution to the budget a schedule of accommodation offering property will be required. However, to finance the entire budget a residential surcharge of approximately R10 would be required of the average valued property. This figure is well below the average resident population WTP of R15, highlighting the fact that an environmental surcharge in Plettenberg Bay is indeed feasible. The difference in reported WTP and the contribution required to finance the Bay Management Plan also highlights that there is scope for experimentation in the introduction of such a surcharge.

In addition to this the style is capable of adapting to dynamic local coastal conditions and is therefore an appropriate direction in which to steer coastal management in South Africa. The effectiveness of coastal co-management as an informal institutional arrangement is then examined. Provided that local Coastal Management Fora are created to include all relevant stakeholders and that a source of long term financing is secured co-management has the potential to create the conditions necessary for effective coastal management. With regard to a source of long term financing, local environmental surcharges to finance coastal management initiatives are considered. The public’s willingness to contribute to such a surcharge is analysed in the context of Plettenberg Bay by probing their willingness to pay (WTP) for a Bay Management Plan. A survey instrument is developed to measure the public’s WTP. The design of the instrument is based on the Contingent Valuation (CV) method that is used to analyse the nonmarket benefits that environmental resources (such as Plettenberg Bay) provide the public. It is found that the resident population is willing to pay R15 per month toward a Bay Management Plan whilst domestic and foreign tourists respectively are willing to pay R6 and R22 daily. The aggregation of these WTP estimates yields a total passive use value of between R15 397 900 – R20330 500 annually. This nuclear value of the Bay should be included in the formation of local coastal management policy and provides guidance for the introduction of a local environmental surcharge. A budget for a Bay Management Plan is proposed and a progressive surcharge based on municipal property value is set. To finance the local residents’ share of the budget, a monthly surcharge of R1 would be required of the average valued property. To calculate the domestic and foreign tourist contribution to the budget a schedule of accommodation offering property will be required. However, to finance the entire budget a residential surcharge of approximately R10 would be required of the average valued property. This figure is well below the average resident population WTP of R15, highlighting the fact that an environmental surcharge in Plettenberg Bay is indeed feasible. The difference in reported WTP and the contribution required to finance the Bay Management Plan also highlights that there is scope for experimentation in the introduction of such a surcharge.

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

- 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: 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: 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: 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: 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.
