- Description: This study assesses the effects of an agribusiness collapse, on the contracted growers and their surrounding communities in Lusaka Province, Zambia. In 2004, Agriflora Limited, a Trans-Zambezi Industries Limited (TZI) agribusiness in Lusaka Zambia was sold off. Agriflora Limited was one ofthe largest fresh vegetable exporters in Africa. It had contracted almost 500 small-scale farmers with 1-4 hectares of land within 50 km radius of Lusaka to grow vegetables for export. Makeni Cooperative Society was one of the targeted groups of growers. It grew baby corn, mangetout peas, and sugar snap and fine beans for export. The case study relied on both primary and secondary data. I undertook two months of ethnographic fieldwork utilising observations, in-depth interviews and informal discussions with some community members in Makeni. I also reviewed the literature on contract farming schemes (documenting both the negative and positive effects for growers) in developing countries. The case study showed that the impact of the collapse of Agriflora on the growers has been severe indeed; there has been a significant reduction in production with only a few farmers producing for export. Those that are producing are limited to one crop, baby corn. The effect on the local labour market (farm workers) has been quite drastic with a drop in employment. A new agribusiness company, York Farm, was sourced by the government for the contract growers of Makeni. York Farm has signed a procurement contract under which only sale and purchase conditions are specified. This means that, services such as extension services are no longer provided. It was also found that despite the price for baby corn at York Farm being better than what Agriflora used to offer the farmers, farmers are not producing peas which have a higher turnover than baby corn because York farm does not buy peas from the farmers. However, the farmers are hopeful that they will soon start producing peas after they pass the Eurep gap requirements. Furthermore, the farmers are still interested in contract farming as they are convinced that it can lead to higher farm incomes. While the neoliberal critique of the pre- Structural Adjustment agricultural policies was based on the need to improve rural farming income and productivity, my study shows that the contract farmers are not the "traditional" peasant farmers but retired civil servants or former public sector employees who lost their jobs during the contraction of the sector. In conclusion, my field work revealed that the collapse of Agriflora has had negative effects on the growers of MCS in terms a significant decrease in crop production, decline in farmer income, lack of technical assistance such as extension services, transportation problems (to take produce to the new market-York Farm) and reduced contraction in employment opportunities for farm workers.

- Description: The use of electronic mail (email) has evolved from sending simple messages to task delegation and management. Most mail clients, however, have not kept up with the evolution and as a result have limited task management features available. On the other hand, while issue tracking systems offer useful task management functionality, they are not as widespread as emails and also have a few drawbacks. This thesis reports on the exploration of the integration of the ubiquitous nature of email with the task management features of issue-tracking systems. We explore this using simple ad-hoc as well as semi-automated tasks. With these two working together, tasks can be delegated from email clients without needing to switch between the two environments. It brings some of the benefits of issue tracking systems closer to our email users.The system is developed using Microsoft VisuaI Studio.NET. with the code written in C#. The eXtreme Programming (XP) methodology was used during the development of the proof-of-concept prototype that demonstrates the integration of the two environments, as we were faced at first with vague requirements bound to change, as we better understood the problem domain through our development. XP allowed us to skip an extended and comprehensive initial design process and incrementally develop the system, making refinements and extensions as we encountered the need for them. This alleviated the need to make upfront decisions that were based on minimal knowledge of what to expect during development. This thesis describes the implementation of the prototype and the decisions made with each step taken towards developing an email-based issue tracking system. With the two environments working together, we can now easily track issues from our email clients without needing to switch to another system. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This thesis investigates the movement behaviour of South African two coastal fish species and evaluates the effectiveness of marine protected areas (MPAs) in their protection and management. Its primary focus is on resolving the movement patterns of roman Chrysoblephus laticeps (Sparidae) in and around the Goukamma and Castle Rock MPAs in the Western Cape province of South Africa. A pilot study of the methodology investigated the movement behaviour of spotted grunter Pomadasys commersonnii (Haemulidae) in the sheltered East Kleinmonde Estuary in the Eastern Cape province. The application of different tagging methods was tested in a controlled tank experiment. Tagged roman were monitored over a 198-day period. Barbed dart, t-bar anchor and Visible Implanted Fluorescent Elastomer (VIFE) tags were compared. Application techniques and underwater visibility of VIFE tags were tested on roman and on fransmadam Boobsoidia inornata in a pilot study. Needles of gauge 25 were found to be optimal for VIFE tag application. Whereas VIFE tagging caused fin rot in fransmadam, it had no negative effect on roman. VIFE tagged fish could be identified by divers from a distance of three metres under ambient light in an observation tank in five metres water depth. There was no significant difference in growth rate between groups of roman with different tags and controls after 198 days. High tag loss rates were experienced for barbed dart and t-bar anchor tags, although barbed dart tags performed better than t-bar anchor tags. Although some of the VIFE marks had deteriorated, all VIFE tagged fish were individually recognised at the end of the study. Conventional dart and VIFE tags are feasible methods to tag roman. However, the high tag loss rate of conventional tags must be taken into account in the design of a tagging study. Previous mark and recapture studies on roman are beset with a number of problems. Poor experimental design and low precision of capture positions resulted in equivocal results of limited value. A tagging experiment was designed to eliminate ambiguity in data interpretation and to produce a dataset that could be used to model roman residency and dispersal. A combination of conventional barbed dart tags and Visible Implanted Fluorescent Elastomer tags was used to tag roman in the Goukamma Marine Protected Area (GMPA) on the temperate South African south coast. Sixty one percent of roman were recaptured within 50 m of the tagging position. A small proportion moved considerable distances of up to four kilometres. The extent of these movements was not dependent on fish size or sex. Data from this experiment and from a previous tagging study in the Tsitsikamma National Park (TNP) were used to model the resident behaviour of roman. The model suggests a probability of 91% (GMPA) and 94% (TNP) of residency within a 10000 m² cell. This result suggests that individual roman will benefit from protection in small MPAs. A different experimental approach was required to investigate the exact home range of this species. Firstly the feasibility of using acoustic telemetry to study the movement of coastal fish in South Africa was investigated. The telemetry equipment comprised two VEMCO V8 transmitters and a VEMCO VR60 receiver linked to a directional hydrophone. A tank experiment was conducted to examine the effects of the transmitter implantation. A tracking experiment was conducted on spotted grunter Pomadasys commersonnii in the East Kleinmonde Estuary. Operated fish recovered quickly and, with respect to swimming behaviour and growth rates, no differences were found between fish with implants and controls. The maximum detection range in the estuary was 400 m. Interference between different transmitter frequencies was negligible. Transmitter location recordings were found to be accurate within five metres. Two fish were tracked over a seven-day period. The fish preferred the lower reaches of the estuary where they made repeated and prolonged use of specific areas. The success of the initial experiments allowed this method to be used to investigate the spatial utilisation and activity patterns of roman Chrysoblephus laticeps. Surgically implanted VEMCO V8, V13 and V16 transmitters were used to track 13 roman inside the Castle Rock MPA in False Bay. Transmitters implanted into C. laticeps in tanks had no apparent effects on growth and physiology. Manual boatand diver-based tracking experiments covered a 17-month period. A VEMCO VRAP radio acoustic positioning system was used over two one-month periods during and after the spawning season of roman. Analysis of data using a 95% fixed kernel algorithm suggests that roman are resident throughout their adult life, occupying home ranges between 1000 and 3000 m². Activity was lower at night. During periods of cold-water upwelling, fish retreated into caves. During the spawning season, females extended their home ranges, possibly to mate with different males. These results confirm that this species is well suited for protection and management with small MPAs. The effect of two MPAs on the South African south coast on the population of C. laticeps was simulated with a spatially explicit individual based model (IBM). Life history parameters determined in recent studies and the effect of fishing on the size of sex change was taken into account. Fish densities and size frequencies were based on recent underwater visual census. The distribution of suitable habitat in the study areas was also incorporated. The results show a rapid recovery of the fish size frequency spectrum and sex ratio to pre-exploitation levels inside both MPAs. Little 'spillover' of fish into the fished areas occurred resulting in negligible improvement of catches. The results suggest that for resident species like roman, even small MPAs offer sufficient protection.

- Description: This case study investigates sense of place of youth amidst a background of change in postapartheid South Africa. As used in this study, sense of place refers to the attachments made to both physical and social places, and the social and cultural interactions and meanings associated with such places. The research was conducted with a group of 13 young adults at Mary Waters Senior Secondary School in Grahamstown. The literature suggests that the changes that occur in the lives of the participants at school-leaving age such as new opportunities to identify with global aspirations, tend to influence their sense of place in local contexts. Social change that occurs due to globalising forces such as access to new technologies and improved personal mobility, also influences sense of place in this context. Another integral factor is the structural influence of changing cultural and educational norms. These notions form part of the backdrop of this study. The research project was developed in response to calls for learning approaches that are situated more in local contexts and which include the youth as intrinsic participants informing environmental education approaches. This research draws attention to the significance of finding sustainable ways that enhance opportunities for agency on the part of the youth in future local and global environmental care-taking. The study took place over a period of 15 months in which time the participants undertook place-based activities in their communities around self-identified environmental concerns. The study was intentionally generative in approach as this allowed the voices of the participants and their environmental perspectives to be considered in developing methods and activities that were suitable to their particular contexts and interests. The study highlights the relevance of particular social contexts, through the perspectives of people and in this case learners, as key to environmental education enquiries. The combination of approaches that consider: a) knowledge about social context, b) the educational intervention (place-based activities) and, c) the situated social capital of the participants, all form the basis of meaningful pedagogical engagements and serve to address my research question: How is learners' sense of place developed and articulated through place-based activities, and what are the implications for environmental education amidst a contemporary landscape of change in South Africa?

- Description: This study is a contribution to the literature on South Africa's foreign policy since 2000-2004. It provides a theoretical framework within which South Africa's foreign policy should be understood. It attempts to explain the contradictions that have been apparent in South Africa's foreign policy by looking at the constraints inherent in South Africa's position as an emerging middle power. It argues that South Africa's pluralist inclinations are constrained by Africa's evolving multilateral forums and that South Africa's preference for such undermines the realization and achievement of her foreign policy principles and goals. It also argues that as a realist middle power, South Africa is constrained the ambivalence shown by the region towards her exercising leadership in the region. This is due to South Africa's history of destruction in Southern Africa in the 1980's. South Africa's quiet diplomacy towards Zimbabwe provides the focal point for the study. The study argues that it is not the case that South Africa is not concerned with human rights abuses in Zimbabwe. Instead, this concern has been expressed in ways that do not tarnish South Africa's own image in Africa. This has been done by engaging Zimbabweans through multilateral forums. This study concludes that this strategy failed to bring about resolution to the Zimbabwean crisis.

- Description: In the current business climate, performance is increasingly determined by how flexibly and effectively companies can utilize their human resources and this in tum, is influenced by employee morale. Morale refers to a state of psychosomatic health marked by an energetic, decisive resolution to achieve a given goal. When morale is low, employees may do what is required but do not have the energy to 'go the extra mile'. The importance of maintaining high morale is thus evident. The following project involved a study of morale in Cadbury's Port Elizabeth plant. Cadbury management was concerned about low morale following a recent merger with Bromor Foods. They thus wanted to assess: the state of current morale; any factors that may be influencing it; indicators of low morale (so that it may be monitored in the future) and finally, ways of addressing any existing morale issues. In order to achieve these aims, the researcher conducted interviews with various people to explore morale issues from employees' perspectives. She then sought confirmation for these views at the organizational level through the use of a survey. Statistical and thematic analyses showed morale to be low for middle managers and revealed a variety of indicators and influencing factors, as well as suggestions for addressing them. Despite the need to boost the sample size with convenience sampling, and thus, reduced representivity, the research was successful in answering the research aims.

Despite the need to boost the sample size with convenience sampling, and thus, reduced representivity, the research was successful in answering the research aims.

- Description: The population structure and feeding dynamics of the hyperiid amphipod, Themisto gaudichaudii, was investigated during two cruises of the South African National Antarctic Programme conducted in the Indian sector of the Polar Frontal Zone during austral autumn (April) 2004 and 2005. During the 2004 cruise the frontal features that delimit the PFZ converged to form a single distinctive feature. In 2005, the research cruise was conducted in the vicinity of a cold-core eddy which was spawned from the Antarctic Polar Front. Total mesozooplankton abundance and biomass during the 2004 study ranged from 55.19 to 860.57 ind. m⁻³, and from 2.60 to 38.42 mg dwt m⁻³, respectively. In 2005 the abundance and biomass ranged from 23.1 to 2160.64 ind. m⁻³, and from 0.76 to 35.16 mg dwt m⁻³, respectively. The mesozooplankton community was numerically dominated by copepods, pteropods, and ostracods during both surveys. The abundance and biomass of Themisto gaudichaudii in the region of investigation was < 0.2 ind. m⁻³ (range 0.01 to 0.15 ind. m⁻³) and < 0.06 mg dwt m⁻³ (range 0.02 to 0.06 mg dwt m⁻³) during 2004, while in 2005 the abundance and biomass of the amphipod ranged from < 0.01 to 0.2 ind. m⁻³ and < 0.01 to 0.04 mg dwt m⁻³, respectively. These values correspond to < 1% of the total mesozooplankton abundance and biomass during both surveys. T. gaudichaudii exhibited no significant spatial patterns in abundance, biomass and total length during both 2004 and 2005 (p > 0.05 in all cases). A key feature of the two investigations was the virtual absence of juveniles (total length < 15 mm) among the amphipod population, supporting the suggestion that they exhibit strong seasonal patterns in reproduction. Gut content analysis during both years indicated that for both the male and female amphipods’, copepods were the most prevalent prey species found in stomachs, followed by chaetognaths and pteropods. Results of electivity studies indicate that T. gaudichaudii is an opportunistic predator, generally feeding on the most abundant mesozooplankton prey. Results of in vitro incubations indicated that the total daily feeding rate of T. gaudichaudii during 2004 ranged from 11.45 to 20.90 ind. m⁻³ d⁻¹, which corresponds to between 0.12 and 1.64% of the total mesozooplankton standing stock. In 2005, the feeding rate ranged between 0.1 and 1.73% of the total mesozooplankton standing stock. The low predation impact of T. gaudichaudii during this study can be related to their low abundances and high interannual variability throughout the region of investigation.

- Description: The development of small (<300 km²), private game reserves has become a trend, not only in the Eastern Cape Province, but also elsewhere in South Africa as a result of a shift in land use practise from agriculture to ecotourism. The resultant re-introduction of elephants to many of these reserves has lead to management concerns because of the limited research on small reserves regarding their impact on the vegetation. In this study I assessed the space use, habitat selection, diet and impact of two elephant populations on the vegetation in the Eastern Cape Province between February 2004 and March 2005. Home range sizes were calculated using the kernel utilization distribution method. Home range sizes for elephants on Kwandwe were significantly larger during summer than winter (p<0.05). There was no significant difference between the home range sizes of the herds and males within a season and during summer the elephants utilized about 75 % of the reserve and only 54 % during winter. On Shamwari, the herd utilized about 92 % of the reserve during summer and 83 % during winter; while the males utilized 76 % of the reserve. Core areas for both elephant populations shrank from summer to winter and were concentrated around the permanent water sources on each reserve. Habitat selection was assessed using χ² tests and Bonferroni confidence intervals. On Kwandwe, there was a significant difference between observed and expected use of vegetation types (p<0.05) and karroid shrubland was strongly avoided by both herds during summer and winter. The preferred vegetation types of the males ranged from relatively open (short euphorbia thicket, bushclump karroid thicket and karroid shrubland) to completely open (old lands). On Shamwari, subtropical thicket, bontveld and montane grassland were avoided; while primary and secondary acacia thicket, riverine thicket and cultivated lands were preferred. The predominant vegetation type in the home ranges of herds on Kwandwe and Shamwari was subtropical thicket. The diet was assessed by direct observations over two seasons and dietary preferences were calculated. There was a significant difference in the frequency of occurrence of plants in the diet on the two reserves (p<0.05) and no significant effect of time of day or season (p>0.05). Seventeen woody plant species were utilized on Kwandwe and 23 species were utilized on Shamwari. Grass constituted a significantly greater percentage of the diet in summer than winter (p<0.05). Elephants on Kwandwe showed a selective preference for Ozoroa mucronata, Pappea capensis and Acacia karroo; while on Shamwari, A. karroo was selected. Transects were conducted in two different vegetation types on each reserve so as to assess the impact of elephant on the vegetation and damage scores were then calculated from these data. There was no significant effect of vegetation type or elephant density on mean damage scores in Kwandwe (p>0.05). Five hundred and seventy-eight plants were assessed in the subtropical thicket vegetation type and 225 plants were assessed in the savanna-type vegetation, with more than half the trees showing low levels of damage that could not only be attributed to elephants. Mean damage was highest for Portulacaria afra and Pappea capensis in subtropical thicket and for Rhus spp. in the savanna-type vegetation. On Shamwari, 408 plants were assessed in subtropical thicket and 215 in the savanna-type vegetation, with more than 70 % of trees showing low levels of damage. There was a significant effect of plant species and elephant density on the mean damage scores in subtropical thicket, with Aloe ferox showing more damage than the other plant species (p<0.01). In the savanna-type vegetation, A. karroo was the most severely damaged. Overall, damage was greater in the thicket vegetation type compared to the more open vegetation type on both reserves.

- Description: Financial reforms were a major component of structural adjustment programs deemed necessary for developing countries in the mid 1980s. These were not only meant to improve the sector, but would ultimately enhance economic growth and help in poverty alleviation. At the top of these reforms was financial liberalisation. Kenya, like many other sub-Saharan African countries, undertook financial liberalisation in 1991, one of the measures was decontrolling interest rates. With market driven interest rates in place it was assumed that there would be increased efficiency in bank lending, as well as growth in credit availability as deposits increased. A key indicator of this improved intermediation process would be a narrowing interest rates spread, that is, the margin between the deposit and lending rate. Paradoxically, however, the expected benefits of these reforms did not accrue to Kenya's banking sector. This study focuses on financial reforms and the spread of interest rates in Kenya's banking sector. Using a trend analysis, spanning the period before and after liberalisation, interest rates spread are shown to have escalated dramatically upwards after liberalisation. An analysis of three macroeconomic variables, namely, the exchange rate, inflation rate and economic growth offer little, or inconclusive evidence, that they were the main causes of the wide interest rate spread. In fact, the spread is closely linked to institutional/structural factors such as non-competitiveness in the banking sector, imprudent lending practices and poor and/or inadequate banking supervision. Policies for improving the institutional infrastructure and thus moderating the spreads are highlighted.

- Description: This thesis defends an ontological and epistemological account of Michel Foucault's post-structuralist philosophy, to argue that political philosophy needs to take into account the historical and political contingency of subjectivity and discourse. I show that by addressing the historical and political contingency of knowledge, Foucault's work overcomes the flaw of foundational epistemology in political philosophy, which treats true discourse as universal and disinterested. In doing so I hope to have to refuted the mainly positivistic and humanist schools of thought that lay claim to universal and foundationalist notions, by demonstrating the extent to which their misgivings about Foucault's work are informed by and founded upon an unjustified a-historicism. The thesis is composed of three chapters, the first of which deals with an ontology of the subject, the second, with an ontology of social relations, and the last with epistemology. In each chapter I use dialectical analysis to reveal how interests necessarily mediate subjectivity, social relations, and knowledge. The first two chapters defend Foucault's conception of power, by way of an analysis of the relations between Foucault's work and Sartre's existential phenomenology. I show how both Foucault and Sartre successfully address the problem of historicism for political philosophy with their respective conceptions of human freedom. The final chapter defends Foucault's conception of the relations between power and discourse, to show how it overcomes the a-historicism of universal, foundational epistemology. These three chapters demonstrate the importance of accounting for historicism in political philosophy. Claims to universal interest, because knowledge is conditioned by conflicts of interest, often mask political domination. It is important, then, to remember, in political philosophy, that knowledge is evaluative and interested, reflecting historically and politically mediated evaluations. One should be suspicious of ' natural facts' , used to justify actions or beliefs, thereby masking the choices that inform them. I have used the work of Michel Foucault to motivate this claim.

- Description: The North Eastern Cape in South Africa is part of a larger province that is in desperate need of job creation and economic development. In light of these needs, efforts have been made by members of the community and outside investors to generate new forms of income in the area. These economic developments emerged in the form of small-scale tourism initiatives and commercial forestry. The impact of these developments on the small community of Maclear differs in nature and is bringing about social change and influencing identity. In this thesis, I explore the effects of each of these developments on the local farming community, particularly the established white English-speaking farmers. For various important reasons, such as the changes to land use patterns occurring around them in terms of forestry and tourism initiatives, I chose to examine the situation of this minority. In general discussions and portrayals of white farmers, it is hypothesized that whites living in small farming communities are resistant to change, politically stagnant and socially conservative. In this thesis I test this hypothesis and investigate what South Africans might see as the core, or whether there is a core of, white settler identity. TIle idea of 'frontiers' being heartlands was emphasized in Maclear as residents spoke about the pioneering efforts of their forefathers and discussed these efforts as the essence of their identity. Forestry is a contemporary ' frontier' encroaching on these white Settlers. A dynamic concept of landscape is central to these identity construction efforts. In this thesis I explore, through different articulations of landscape, how residents, recent arrivals and investors attempt to embed their identity and resources in the community.

- Description: The North Eastern Cape in South Africa is part of a larger province that is in desperate need of job creation and economic development. In light of these needs, efforts have been made by members of the community and outside investors to generate new forms of income in the area. These economic developments emerged in the form of small-scale tourism initiatives and commercial forestry. The impact of these developments on the small community of Maclear differs in nature and is bringing about social change and influencing identity. In this thesis, I explore the effects of each of these developments on the local farming community, particularly the established white English-speaking farmers. For various important reasons, such as the changes to land use patterns occurring around them in terms of forestry and tourism initiatives, I chose to examine the situation of this minority. In general discussions and portrayals of white farmers, it is hypothesized that whites living in small farming communities are resistant to change, politically stagnant and socially conservative. In this thesis I test this hypothesis and investigate what South Africans might see as the core, or whether there is a core of, white settler identity. TIle idea of 'frontiers' being heartlands was emphasized in Maclear as residents spoke about the pioneering efforts of their forefathers and discussed these efforts as the essence of their identity. Forestry is a contemporary ' frontier' encroaching on these white Settlers. A dynamic concept of landscape is central to these identity construction efforts. In this thesis I explore, through different articulations of landscape, how residents, recent arrivals and investors attempt to embed their identity and resources in the community. I ask whether it is possible for members of the white community to produce an alternate and politically viable interpretation of landscape in post-apartheid South Africa. Can land and landscape offer them a sense of belonging and identity? What is their experience in view of the impositions of major investors who see land purely as an economic unit?

- Description: This thesis explores various dilemmas in making theatre performances in the context of social disruption, trauma and death. Diverse discourses are drawn in to consider issues of body, subjectivity and spectatorship, refracted through the writer’s experiences of and discontent with making theatre. Written in a fractal-like structure, rather than a linear progression, this thesis unsettles discourses of truth, thus simultaneously intervening in debates about the epistemologies of the body and of theatre in context of the academy. Chapter 1: Methodological Anxieties Psychoanalytic theory provides a way in for investigating the dynamics of theatrical performance and its corporeal presence, by focusing on desire and its implication in the notions of loss and anxiety. The theories of the unconscious and the gaze have epistemological implications, shifting definitions of “presence” and “truth” in theatre performance and writing about theatre. This chapter tries to outline the rationale for, as well as to enact, an alternative methodology for writing, as an ethical response to loss that does not insist on consensus and truth. Chapter 2: (Refusing to) Look at Trauma This chapter examines the politics that strives to make suffering visible. Discursive binaries of public/private, dead/living, and invisible/visible underlie the politics of AIDS and sexuality. These discourses impact on the reception of Bill T. Jones's choreography, despite his use of modernist artistic processes in search of a bodily presence that aims to collapse the binary of representation (text) and its subject (being). The theory of the gaze shows this politics to be a phallocentric discourse; and narrative analysis traces the metanarrative that results in the commodification of oppositional identities, so that spectators participate in the politics as consumers. An ethical artistic response thus needs to shift its focus to the subjectivity of the spectator. Chapter 3: The Screen and the Viewer’s Blindness By appealing to a transcendent reality, and by constituting spectators as a participative community, ritual theatre claims to enact change. The “truth” of ritual rests not on rational knowledge, but on the performer’s competence to produce a shamanic presence, which director Brett Bailey embraces in his early work. Ritual presence operates by identification and belonging to a father/god as the source of meaning; but it represses the loss of this originary wholeness. Spectators of ritual theatre are drawn into an enactment of communion/community, the centre of which is, however, loss/emptiness. The claim of enacting change becomes problematic for its absence of truth. Bailey attempts to perform a hybrid, postcolonial aesthetics; but the problem rests in the larger context of performing the notion of “South Africa”, a communal identity hardened around the metanarrative of suffering, abjecting those that do not belong to the land of the father/god – foreigners that unsettle the meaning of South African identity. Conclusion: Bodies of Discontent The South African stage is circumscribed by political and economic discourses; the problematization of national identity is also a problematization of image-identification in the theatre. In search for a way to unsettle these interrogative discourses, two moments of performing foreignness are examined, one fictional, one theatrical. These moments enact a parallel to the feminine hysteric, who disturbs the phallocentric truth of the psychoanalyst through body performance. These moments of disturbing spectatorship are reflected in the works of performance artist Marina Abramovic. Her explorations into passive-aggression, shamanism and finally theatricality and the morality of spectatorship allow for an overview of the issues raised in this thesis regarding body, viewing, and subjecthood. Sensitivity to the body and its discontent on the part of the viewer becomes crucial to ethical performance.

Habitat segregation in competing species of intertidal mussels in South Africa

- Description: Mytilus galloprovincialis is invasive on rocky shores on the west coast of South Africa where it has become the dominant intertidal mussel. The success of this species on the west coast and its superior competitive abilities, have led to concern that it may become invasive on the south coast at the expense of the indigenous mussel Perna perna. On shores where these species co-occur, there appears to be habitat segregation among zones occupied by mussels. M.galloprovincialis dominates the high-shore and P.perna the low-shore, with a mixed zone at mid-shore level. This study examined the factors responsible for these differences in distribution and abundance. The study was conducted in Plettenberg Bay and Tsitsikamma (70km apart) on the south coast of South Africa. Each site included two randomly selected locations (300-400m apart). A third mussel species, Choromytilus meridionalis, is found in large numbers at the sand/rock interface at one location in Plettenberg Bay. Aspects of settlement, recruitment, growth and mortality of juvenile and adult mussels were examined at different tidal heights at each site. Quantitative analysis of mussel population structure at these sites supported the initial observation of vertical habitat segregation. Post-larvae were identified to species and this was confirmed using hinge morphology and mitochondrial DNA analysis. Size at settlement was determined for each species to differentiate between primary and secondary settlement. Adult distribution of C.meridionalis was primarily determined by settlement, which was highly selective in this species. Settlement, recruitment and growth of P.perna decreased with increasing tidal height, while post-settlement mortality and adult mortality increased higher upshore. Thus all aspects of P.perna’s life history contribute to the adult distribution of this species. Presumably, the abundance of P.perna on the high-shore is initially limited by recruitment while those that survive remain prone to elimination throughout adulthood. M.galloprovincialis displayed the same patterns of settlement and recruitment as P.perna. However, post-settlement mortality in this species was consistently low in the low and high zones. Juvenile growth also decreased upshore, suggesting that M.galloprovincialis may be able to maintain high densities on the high-shore through the persistence of successive settlements of slow-growing individuals. The low cover of M.galloprovincialis on the lowshore appeared to be determined by adult interactions. M.galloprovincialis experienced significantly higher adult mortality rates than P.perna in this zone. There were seasonal variations in the competitive advantages enjoyed by each species through growth, recruitment or mortality on the low-shore. In summer, P.perna had higher recruitment rates, faster growth and lower mortality rates, while M.galloprovincialis had slightly higher recruitment rates and faster growth rates in winter. P.perna is a warm water species while M.galloprovincialis thrives on the cold-temperate west coast of South Africa. Therefore both species appear to be at the edge of their optimal temperature regimes on the south coast, which may explain the seasonal advantages of each. Nevertheless, P.perna has maintained spatial dominance on the low-shore suggesting that it may ultimately be the winner in competition between these species. M.galloprovincialis appears to have a refuge from competition with P.perna on the high-shore due to its greater tolerance of desiccation stress, while being competitively excluded from the low-shore. Warm water temperatures coupled with poor recruitment rates at most sites may limit the success of M.galloprovincialis on this coast.

- Description: A number of companies have developed a variety of network approaches to the transfer of audio and MIDI data. By doing this, they have addressed the configuration complications that were present when using direct patching for analogue audio, digital audio, word clock, and control connections. Along with their approaches, controlling software, usually running on a PC, is used to set up and manage audio routings from the outputs to the inputs of devices. However one of the advantages of direct patching is the conceptual simplicity it provides for a user in connecting plugs of devices, the ability to connect from the host plug of one device to the host plug of another. The connection management or routing applications of the current audio networks do not allow for such a capability, and instead employ what is referred to as a two-step approach to connection management. This two-step approach requires that devices be first configured at the transport layer of the network for input and output routings, after which the transmit and receive plugs of devices are manually configured to transmit or receive data. From a user’s point of view, it is desirable for the connection management or audio routing applications of the current audio networks to be able to establish routings directly between the host plugs of devices, and not the audio channels exposed by a network’s transport, as is currently the case. The main goal of this work has been to retain the conceptual simplicity of point-to-point connection management within digital audio networks, while gaining all the benefits that digital audio networking can offer.

- Description: This thesis aims to provide a better understanding of the ways in which the Internet supports the consumer decision process of potential customers in an online car retail environment. The thesis is mainly focused on how this can be done in South Africa. A case study approach was adopted in investigating the case of McCarthy Call-a-Car. Interviews were carried out with McCarthy Call-a-Car employees and documents and the Call-a-Car website, were analysed. It was revealed that Call-a-Car focuses on using the Internet to support customers in the pre-purchase phase only. The purchase and post-purchase phases are carried out offline at its dealership network and Club McCarthy respectively. The findings showed that Call-a-Car views the Internet as a marketing tool that provides convenience to customers searching for product information in the pre-purchase phase. The interviews revealed that due to Call-a-Car's strategy, as well as practical problems of selling online, the customer will still have to visit a dealership to conclude a purchase and for post-purchase support. From this research it appears that there are three main issues arising out of Call-a-Car's usage of the Internet in the customer buying process: firstly, the research revealed that instead of cutting out the middle-man, the Internet has created new types of intermediaries called "cybermediaries" and that Call-a-Car is one such intermediary. Secondly, it was revealed that trust is crucial in the online environment and that Call-a-Car builds trust through branding. Thirdly, the Internet has not affected prices online, despite theoretical estimations that the Internet would induce lower prices. The main recommendations for future research are empirical studies to investigate if the cybermediary model is unique to the car industry and whether this business model could be applied to other look and feel industries such as real estate. Future studies could also investigate the mechanics of trust-building and brand-building in the online environment and finally, studies from the customer perspective considering what Internet tools the customer would like to see online to support them during their buying decision process.

- Description: September 11, 2001 presented the world with events that challenged its conception of reality and called into question current ideologies. In order to make sense of the attacks, people turned to the media for information and interpretation. My interest lies in the media’s role in shaping ideologies as a result of the events of September 11, 2001. I focus on the newspaper editorial because it, in particular, functions not only to report the news but also to interpret the news for the reader. My analysis is centred on the first reaction to the events in five ‘core’ editorials drawn, respectively, from an American, British, South African, Zimbabwean and Kenyan newspaper. The specific focus, in each case, is the representation and evaluation of social actors, the events themselves and the schematic structure of the editorial. I adopt a critical perspective through the use of Critical Discourse Analysis, supported by Systemic Functional Grammar and APPRAISAL. This perspective involves three inter-connected stages of analysis: a Description of the formal discourse properties of each editorial; an Interpretation of the prevailing situational context; and an Explanation of the sociohistorical context in each case. Language, being a form of social practice, is a means by which power relations in society are reproduced or contested (Janks 1997). By analysing the editorials’ discourse I identify whose interests are being served and how each text positions a reader’s attitudes and opinions. My analysis reveals the fact that the editorials distinguish between “us” and “them” groups for the purposes of advancing and confirming in-group ideologies and agendas. This is achieved in each case through comparing the paper’s ideology with the opposing ideology, which is presented as deviant and unsupportive of the in-group. My analysis of the African editorials, in particular, further reveals the exploitation of this division for the purposes of promoting and interpreting local political and social issues. Examination of the processes and conditions surrounding the production of the editorials shows how they are significantly influenced and constrained by the ideologies of both the writer and newspaper owner as well as by the situational context within which they were written.

- Description: September 11, 2001 presented the world with events that challenged its conception of reality and called into question current ideologies. In order to make sense of the attacks, people turned to the media for information and interpretation. My interest lies in the media’s role in shaping ideologies as a result of the events of September 11, 2001. I focus on the newspaper editorial because it, in particular, functions not only to report the news but also to interpret the news for the reader. My analysis is centred on the first reaction to the events in five ‘core’ editorials drawn, respectively, from an American, British, South African, Zimbabwean and Kenyan newspaper. The specific focus, in each case, is the representation and evaluation of social actors, the events themselves and the schematic structure of the editorial. I adopt a critical perspective through the use of Critical Discourse Analysis, supported by Systemic Functional Grammar and APPRAISAL. This perspective involves three inter-connected stages of analysis: a Description of the formal discourse properties of each editorial; an Interpretation of the prevailing situational context; and an Explanation of the sociohistorical context in each case. Language, being a form of social practice, is a means by which power relations in society are reproduced or contested (Janks 1997). By analysing the editorials’ discourse I identify whose interests are being served and how each text positions a reader’s attitudes and opinions. My analysis reveals the fact that the editorials distinguish between “us” and “them” groups for the purposes of advancing and confirming in-group ideologies and agendas. This is achieved in each case through comparing the paper’s ideology with the opposing ideology, which is presented as deviant and unsupportive of the in-group. My analysis of the African editorials, in particular, further reveals the exploitation of this division for the purposes of promoting and interpreting local political and social issues. Examination of the processes and conditions surrounding the production of the editorials shows how they are significantly influenced and constrained by the ideologies of both the writer and newspaper owner as well as by the situational context within which they were written. My analysis of the schematic structure of the editorials, in line with Bolivar (1994), reveals consistent use of three-part structures by which editorial opinions are evaluated. In concluding I provide suggestions, based on my research, for how critical language awareness can inform media education at high school level in South Africa. I argue that students should be equipped with tools, such as those I employed, to critically analyse and uncover how language is used to promote ideologies in the editorial of newspapers.
