- Description: Free and fair elections, accompanied by smooth transitions of democratically elected leaders, constitute one of the key pillars of democracy. The dawn of democratisation and advent of multi-party politics after the end of the Cold War in 1991, seemingly held great promise for Africa. However, in recent years, many elections in Africa have consistently become a source of violence. Electoral violence is threatening to become an intractable source of conflict on the African continent, making it hard for emerging democracies to consolidate their status as free democratic societies. Many remain largely autocratic or semi-democratic. African leaders are all too often not ready to relinquish political power, while political elites are ‘power hungry’ and use violence to skew the outcomes of elections in their favour. Hence, electoral violence is employed in order to manipulate civilian election choices and outcomes. Election violence is often deliberately used to target civilians, and in countries like Kenya involves inter-ethnic clashes. These “new wars” are fought unconventionally using ‘crude weapons’, (Kaldor 2013). Kaldor describes how these ‘new wars’ are fought as intra-state (within the state) wars in developing countries. Often, they are waged via state or county networks based on identity or ethnicity. The consequences of electoral violence include the destruction of property, reversed development, injuries, rape, death, internally displaced persons and refugees. Electoral violence persists despite attempts to contain it and measures to effectively manage these processes often prove to be inadequate. The study utilises an exploratory case study of Kenya during 2007-2008 Post-Election violence. The causes, the immediate steps that were initiated to mitigate violence and the reforms undertaken to generate peace structures and prevent future occurrences of post-election violence were explored. Forty-five participants representing involved citizens, negotiators and mediators were interviewed. The research was triangulated via the interview process, together with the use of primary document analysis and an extensive review of the literature. The data was analysed via the use of grounded theory. The research findings reveal that the causes of electoral violence are multi-faceted and multi-layered, with deep underlying issues. The causes include weak institutions, corruption, a non-representational electoral system, ethnicity and ethnic militia. Further causes include statelessness as experienced by certain groups, abuse of state resources and human rights violations. The role of political elites who withhold crucial information, thus denying the public the opportunity to make informed choices during elections was also found to contribute to electoral violence. Other information-related causes include biased media and sensational reporting. Findings also show that socio-economic issues such as poverty, unemployment, scarce resources and unmet basic human needs cannot be underestimated. Lastly, the causes of electoral violence included diverse interests of internal and external actors at play during elections. The findings revealed that although the Kenyan mediation process included the signing of a peace agreement, the root causes of electoral violence such as corruption, weak institutions, abuse of state resources and the unjust electoral system were not adequately addressed. A model for mediation for electoral violence which was explored and developed sought to build on the strengths of the Kenyan mediation process and address its inherent weaknesses, thus making this a significant contribution flowing from the study. The election model for mediation proposes certain key phases which include a pre-mediation process that will ensure a cessation of all hostilities; the mapping of the root causes of electoral violence and electoral reforms that provide resolutions that are acceptable to all the parties. Training of personnel at all levels of government to implement these reforms is also proposed. These measures can ensure the integrity and independence of electoral institutions from political manipulation. Training constitutes a crucial stage in the process of consolidating the emerging democracies. The model for mediation developed is therefore not only meant to mitigate electoral violence but is also intended to serve as a preventive measure. Many African states currently experience structural weaknesses similar to those that existed in Kenya before the 2007-2008 elections (and still persist). These fault lines include corruption, weak institutions, human rights violations, and lack of information. The proposed model for mediation which aims to counter these problems can thus be applied and adapted for implementation in Africa and globally. Several recommendations with implications for policy development are proposed to curb electoral violence. They include constitutional reforms, training of government and electoral officials and the introduction of a properly representational election system. This study, which focuses specifically on post-election violence, recommends further research investigating the pre-election phase, and ‘voting day’ causes of electoral violence for a more comprehensive approach to electoral violence research.

- Description: Family businesses are major contributors to economies around the world. It is also recognised that family businesses are critical to entrepreneurship, socio- economic development and industrialisation around the world. Women in family business are major contributors to the success of the family business around the world. Limited research is available on the role of women in family business. The research conducted yielded similar results for South Africa. The impact of family business on entrepreneurship and the economy, with respect to socio- economic development, has placed great interest in family business studies in South Africa. This study focused on the role of women in black family business in South Africa. This research found that women in black family business focus on bringing softer skills to the business which are beneficial for people management. In their capacity as managers in the family business, women tend to take on a supportive role to the spouse; they tend to focus on ensuring a harmonious and peaceful culture in the work place. Women in family business have a dual role of ensuring business success and quality family life. They prefer to work in the shadow of their male counterparts. Challenges faced by women in black family business have been identified as the lack of inclusion in strategic decision- making, lack of decision-making career opportunities and the lack of consideration for succession within the business, a lack of business mentorship and ambiguity of roles in the business and in the family. It has been found that the role of women in black family business may be enhanced going forward. This may be done through educational programmes or workshops for management skills for women, networking opportunities and support groups, counselling on work/family management strategies, and spousal sharing of responsibilities in the work- family management relationship. A suggested area for future research is the impact of culture in family business in South Africa.

- Description: In recent years, Human-Computer Interaction (HCI) has become a significant part of modern life as it has improved human performance in the completion of daily tasks in using computerised systems. The increase in the variety of bio-sensing and wearable technologies on the market has propelled designers towards designing more efficient, effective and fully natural User-Interfaces (UI), such as the Brain-Computer Interface (BCI) and the Muscle-Computer Interface (MCI). BCI and MCI have been used for various purposes, such as controlling wheelchairs, piloting drones, providing alphanumeric inputs into a system and improving sports performance. Various challenges are experienced by workers in a warehouse environment. Because they often have to carry objects (referred to as hands-full) it is difficult to interact with traditional devices. Noise undeniably exists in some industrial environments and it is known as a major factor that causes communication problems. This has reduced the popularity of using verbal interfaces with computer applications, such as Warehouse Management Systems. Another factor that effects the performance of workers are action slips caused by a lack of concentration during, for example, routine picking activities. This can have a negative impact on job performance and allow a worker to incorrectly execute a task in a warehouse environment. This research project investigated the current challenges workers experience in a warehouse environment and the technologies utilised in this environment. The latest automation and identification systems and technologies are identified and discussed, specifically the technologies which have addressed known problems. Sensory technologies were identified that enable interaction between a human and a computerised warehouse environment. Biological and natural behaviours of humans which are applicable in the interaction with a computerised environment were described and discussed. The interactive behaviours included the visionary, auditory, speech production and physiological movement where other natural human behaviours such paying attention, action slips and the action of counting items were investigated. A number of modern sensory technologies, devices and techniques for HCI were identified with the aim of selecting and evaluating an appropriate sensory technology for MCI. iii MCI technologies enable a computer system to recognise hand and other gestures of a user, creating means of direct interaction between a user and a computer as they are able to detect specific features extracted from a specific biological or physiological activity. Thereafter, Machine Learning (ML) is applied in order to train a computer system to detect these features and convert them to a computer interface. An application of biomedical signals (bio-signals) in HCI using a MYO Armband for MCI is presented. An MCI prototype (MCIp) was developed and implemented to allow a user to provide input to an HCI, in a hands-free and hands-full situation. The MCIp was designed and developed to recognise the hand-finger gestures of a person when both hands are free or when holding an object, such a cardboard box. The MCIp applies an Artificial Neural Network (ANN) to classify features extracted from the surface Electromyography signals acquired by the MYO Armband around the forearm muscle. The MCIp provided the results of data classification for gesture recognition to an accuracy level of 34.87% with a hands-free situation. This was done by employing the ANN. The MCIp, furthermore, enabled users to provide numeric inputs to the MCIp system hands-full with an accuracy of 59.7% after a training session for each gesture of only 10 seconds. The results were obtained using eight participants. Similar experimentation with the MYO Armband has not been found to be reported in any literature at submission of this document. Based on this novel experimentation, the main contribution of this research study is a suggestion that the application of a MYO Armband, as a commercially available muscle-sensing device on the market, has the potential as an MCI to recognise the finger gestures hands-free and hands-full. An accurate MCI can increase the efficiency and effectiveness of an HCI tool when it is applied to different applications in a warehouse where noise and hands-full activities pose a challenge. Future work to improve its accuracy is proposed.

It is a story of dislocation: physical, emotional, and political. It is a story about borders and boundaries; although not rich, I was raised among the rich; although not white, I spent a considerable part of my childhood in white spaces.

- Description: This purpose of this thesis was to explain the resilience of certain micro-enterprises (MEs) in Kampala, Uganda – by focusing on their vulnerability, the assets that they brought to bear on the situation, the role of non-governmental organizations and government institutions in supporting MEs, and the strategies used by ME owners, themselves. As such, it adopts the Sustainable-Livelihoods approach – an approach that has not been used in Kampala before. Thus, it makes a valuable contribution to the field. Designed as a qualitative study, it used in-depth interviews and focus-group discussions. The major findings on vulnerability were linked to: the rising cost of materials; unfair licensing; the struggle to win tenders; local and foreign competition; and the disruption of utilities. The assets used to sustain the welfare of the MEs included: making use of a range of skill-acquisition strategies; leveraging networks; and pooling resources. Financial assets used by MEs revolved around informal savings and credit schemes; but the support given to the MEs through government agencies and NGOs was difficult to assess. Several important strategies were used by ME owners. One of these involved linking with formal construction companies. In addition, temporary workshops constructed out of wood-and-iron, were common. This increased mobility and allowed the re-use of materials. Furthermore, MEs manufactured their own tools, developed new marketing techniques, and diversified their income-generating activities. The significance of this study is two-pronged. It demonstrates that the resilience of MEs does depend on their own positive qualities, but also on an increasingly business-friendly national and international economic environment.

- Description: The object of this thesis is to provide guidelines relating to the tax benefits that are available to investors in immovable property in South Africa. This was done by analysing the various sections of the Income Tax Act, as well as case law and South African Revenue Service guidelines that interpret these sections, which provide for expenditure which may be deducted by taxpayers from their income when conducting the trade of letting immovable property in order to reduce their overall tax liability. The thesis also includes a chapter dealing with the four different types of vehicles that taxpayers may use when investing in property. It was found that there are significant tax benefits available to investors in immovable property through the general deductions provided in terms of section 11(a) of the Act, as well as the specific deductions that the legislature has promulgated for investors in immovable property. It was also found that each of the four vehicles has its own advantages and that a taxpayer’s personal circumstances will dictate which of the vehicles will best suit his or her needs.

- Description: Successful business in today’s competitive climate thrives on building relationships with one’s suppliers, clientele and employees. Businesses, as a form of strategic engagement, extend their appreciation and recognition to these key role players with rewards (or incentives) such as prizes, holidays and free goods and/or services. This treatise examines the taxation implications of such rewards and determines that the market value thereof should be taxed in the hands of their recipients. This study also investigates possible indicators (or points of reference) to establish such market value and suggests alternate values that may be ascribed thereto for inclusion in the recipient’s gross income. Where the rewards are passed onwards by the recipient to its employees, fringe benefit consequences are occasioned and this study observes that the market value thereof should be taxed in the employees’ hands. The study goes on further to consider the position of the supplier (or provider) of the rewards and finds that the supplier is entitled to a deduction of the cost of the rewards it has provided to its clients or customers. This study also reflects upon the penal implications of not including the market value of rewards in gross income and notes that such non-inclusion constitutes a fiscal loss and is subject to an understatement penalty. Key recommendations on how such omission may be addressed by the tax authorities are also presented.

This is a concern given that it is a vulnerable species and likely plays an important ecological role in tropical atoll ecosystems. The aims of this thesis were to investigate the trophic and spatial ecology of juvenile porcupine rays within the St. Joseph Atoll, which is hypothesized to be functioning as a nursery for this species. Specific objectives were to determine i) the dietary composition and resource selectivity displayed by juvenile porcupine rays, ii) residency to the atoll, space use, and seasonality in movements, and iii) whether environmental factors affect short-term movements. Gastric lavage was used to collect stomach contents from 55 juveniles and sediment samples were collected. Thirteen juveniles were implanted with acoustic transmitters and monitored for a year by an array of 88 acoustic receivers situated in and around the St. Joseph Atoll. Porcupine rays appeared to be generalist and opportunistic feeders, foraging predominantly on annelids with the highest environmental availability. Polychaetes of the family Capitellidae were the most important prey item (Index of Importance = 35%). Rays only fed on deep infaunal prey, likely because of their foraging behaviour, suggesting they may influence this community. There was a size-related shift in the crustacean families consumed. The tagged rays displayed high residency to the atoll (mean residency index of 64%) and restricted movements, with small core use and activity space areas (mean of 0.5km² and 3km² respectively) and the majority of detections were recorded within 1km of their tagging locations. The rays favoured the sand ats where 88% of detections occurred. Transient use of the lagoon and fringe reef peaked in the north-west monsoon season, indicating a seasonal usage of these habitats. The effects of temperature and water depth on movements were manifested as diel and tidal cyclical patterns in presence. Evidence illustrates that the St. Joseph Atoll constitutes an important nursery for this species, which has been declared a Marine Protected Area. A major determinant behind the dependence of this nursery habitat is related to predator avoidance. Thermoregulatory behaviours were identified, suggesting that this species is vulnerable to climate change.

- Description: Waterbirds are often overlooked as predators in aquatic ecosystems, despite the fact that waterbirds congregate in great numbers in and around waterways, notably estuaries. To fully appreciate the effect that aquatic feeding waterbird species may have on aquatic prey communities and the role that they play in estuarine food webs, stable isotopes and fatty acid profiles were employed to examine the seasonal diet of selected waterbirds in the Kowie Estuary, Eastern Cape Province, South Africa. Population counts were conducted every month for four seasons to examine the demography of waterbirds in the lower reaches of the estuary. The mean monthly energy consumption, along with dry matter intake of all waterbird species observed, were calculated and compared to similar estuaries in South Africa and elsewhere. Three duck species, one migrant sandpiper and one piscivore were selected for more detailed investigation at several temporal scales. This thesis has revealed that stable isotope analysis of waterbird tissues provides more informative data than fatty acid analysis for investigating waterbird diet and basal resource-tertiary consumer nutrient coupling. Stable δ15N and δ13C isotopes from several body tissues, in conjunction with SIAR models, were used to determine the seasonal diet of each waterbird species, while fatty acid profiles were investigated to examine the trophic transfer of fatty acids from basal resources to waterbird predators via the benthic fauna. Stable isotopes revealed that Cape Shoveller, Cape Teal and Yellow-Billed Duck shifted their diet over both long and short temporal scales, while the migratory Ruff and piscivorous Little Egret maintained a relatively consistent diet over time. Isopods, amphipods, copepods and Mysidacea were the main foods of all three duck species and the Ruff (>30%). Little Egret fed mainly on flathead mullet throughout the year. Fatty acid analysis revealed evidence for trophic transfer of specific fatty acids from basal resources to waterbirds in the Kowie Estuary but provided little information on seasonal diet of waterbirds. Waterbirds foraging in the Kowie Estuary appeared to shift their diet to coincide with resource abundance pulses, but also displayed seasonal dietary overlap. This study highlights the role that waterbirds play in aquatic food webs. The subject requires more attention so that we can better understand all the predatory drivers on aquatic communities.

- Description: The issue of human settlements has recently gained much momentum particularly in cities across the world due to rapid rates of urbanization. The housing crisis is manifesting mostly in the cities of the developing countries; the urban poor population is left with no option, they are continuously living in substandard and unsustainable housing conditions due to the desperate housing need. There is a growing trend of migration into urban centers in the developing countries as well as natural population increase in the cities. The inevitable development is the rapid growth of urbanization. The theories on urbanization suggest that the responsible government and local council authorities must be prepared to address socio-economic issues such as the provision of formal housing, infrastructure development and employment creation. The governments in developing countries are struggling to balance economic development and the provision of social services. As a result, the human settlement sector is suffering lack of prioritization when it comes to budget and resource allocation. The resultant factors are the overcrowding of the urban population, high housing backlogs and dilapidation of infrastructure visible mostly in the major cities of the developing countries.

- Description: The main research problem of this study was to investigate underlying factors, which influence people in the use of outdoor gyms in South Africa. The main research problem gave rise to five research sub-problems. The sub-problems were addressed by the following actions. A literature study was conducted to investigate theories explaining human behaviour. Particular attention was given to the Theory of Planned Behaviour, which provided the basis for the research design. A pilot study was conducted with ten members in the sample group to identify accessible behavioural, normative and control beliefs in order to construct a list of modal accessible beliefs, reflective of the most commonly held beliefs for the population. A standard questionnaire was developed, incorporating Ajzen’s (2002) conceptual and methodological considerations. The self-administered questionnaire was distributed to 974 members of the public from diverse backgrounds. The response rate was 21%, with 203 questionnaires being returned. The final sample size was 156, due to 47 questionnaires being incorrectly completed. The results from the study were largely consistent with the existing literature. A remarkable finding was the strong degree of multi-collinearity displayed between attitude and subjective norms. For this reason, t-stats were used (instead of regression coefficients) to compare the strength of the relationships between the independent and dependent variables. The model explained 34% of the variation in intention to use an outdoor gym. Subjective norms had the strongest significant effect on intentions. Outdoor gym installations are growing globally, as well as in South Africa and local governments regard outdoor gyms as an inexpensive solution to improving public health (Madren, 2013). This study can assist in the design of future physical activity intervention programs. The findings of the study are important as there are a number of public benefits of exercising at outdoor gyms (Madren, 2013: 1). The results of the study revealed the importance of subjective norms in the context of outdoor gyms. The findings further suggested that a special relationship existed between attitudes and subjective norms, which should be considered for effective health interventions. The role of perceived behaviour control is also significant and intervention campaigns should consider a number of proposals suggested in the study.

- Description: The aim of this study is to illustrate how, in the design of costumes, adopting design elements used to produce conceptual fashion can create conceptual costumes that have the ability to express emotions. The play Sounds of South End (2013) contains such qualities; therefore it has been selected to illustrate how the mood and emotional trajectory of a play can be interpreted through symbolism. The play illustrates the life before and after the forced removals during the apartheid (1960s and 1970s), of a fictional family, the Dietrichs, who live in South End, a suburb in Port Elizabeth, South Africa. A focus on the nature of emotional changes experienced by the family has been used to determine the overall mood of the play, leading to a translation of the shifting mood through a collection of conceptual costumes. The final collection was exhibited as an installation artwork that is an interpretation of the altering moods and emotions that occur in the life of the Dietrich family as the play unfolds. The conceptual costumes have been constructed to imbue the narrative of the play with deep meaning by using symbolic elements, such as colour, texture and weight, to suggest the emotional trajectory within the play. The eight costumes portray the interrelated gradual decline and resultant deterioration of human relations experienced by the Dietrichs, from a contented state of harmonious living to a wounded state of despair.

The use of treated brewery effluent as a water and nutrient source in crop irrigation

- Description: Brewery effluent (BE) needs to be treated before it can be released into the environment, reused or used in down-stream activities. Current technologies used to address this concern at the experimental wastewater treatment plant at Ibahyi Brewery (SAB Ltd) include anaerobic digestion (AD), primary facultative ponds (PFP), high rate algal ponds (HRAP) and constructed wetlands (CW). The aim of this work was to determine if BE treated in these systems might be suitable for crop irrigation. A test crop, cabbage (Brassica oleracea cv. Star 3301), grew best on post-AD and post-PFP BE compared to those irrigated with post-HRAP or post-CW effluent. However, the yield was 13% lower than cabbage plants irrigated with a commercial nutrient solution and fresh water. The relatively high conductivity (3019.05 ± 48.72 μs/cm2) of BE may be the main factor reducing the cabbage yields. Post-HRAP and post-CW BE were the least suitable for irrigated crop production due to the higher conductivity and lower nutrient content of these treated effluents. After three months, soils irrigated with post-AD and post-PFP BE had a significantly higher sodium content and sodium adsorption ratio (3919 ± 94.77 mg/kg & 8.18 ± 0.17) than soil irrigated with a commercial nutrient solution (920.58 ± 27.46 mg/kg & 2.20 ± 0.05; p<0.05). However, this was not accompanied by a deterioration in the soil’s hydro-physical properties, nor a change in the metabolic community structure of the soil (p>0.05). After prolonged irrigation with treated BE, sodium is likely to build up in the soil and this can be expected to be accompanied by a deterioration in the soil physical structure. However, crops species such as millet (Echinochloa esculenta), lucerne (Medicago sativa) and saltbush (Atriplex nummularia) reduced the build-up of sodium in the soil. The results suggest that sodium was mainly removed from the soil through plant-assisted leaching. Of the crops grown, lucerne showed the most promise because it improved the soil physical properties, is able to grow well in alkaline environments, is a popular fodder crop and can be harvested multiple times from a single stand. Brewery effluent is more suitable for soil production systems than hydroponic production systems because the soil was able to act as a buffer against the high pH of post-AD BE, whereas in a hydroponics systems the high pH reduced the availability of key minerals to plants. In conclusion brewery effluent contains sufficient plants nutrients to support the growth of cabbages, saltbush, lucerne and millet. However the sodium content of BE is a concern as it accumulates in the soil, and in the long-term it may lead to soil degradation. It is suggested that the brewery change the pH neutralising treatment of BE from sodium hydroxide to potassium hydroxide, or dolomitic lime (calcium and magnesium carbonate) because this would reduce the introduction of sodium into the system, and would increase the suitability of BE for crop production, given potassium and calcium are plant nutrients. The benefits of developing this nutrient and water resource could contribute to cost-reductions at the brewery, more efficient water, nutrient and energy management, create job opportunities with the potential of improving food security in the local community.

- Description: Parental divorce is considered one of the most stressful events in the lives of children. The adult perspective has dominated the discourse on divorce, and only recently has research started to consider the viewpoint of children. Research indicates that the nature of the divorce process as experienced by the child is the most important factor in post-divorce adjustment. It also remains a relatively unexplored area, with research on the manner in which children experience the divorce process being limited. The current study aimed to conduct a narrative inquiry into the experiences and perceptions of parental divorce, of a purposive sample of 9 to 10 year old children. The primary aim of the study was to highlight and honour the voice of the child in a parental divorce process. The current research was qualitative in nature and adopted a narrative paradigm. Five children were interviewed qualitatively using an unstructured interview. Data were analysed using thematic analysis. Seven themes were identified. The first theme explored children’s endeavours to describe and explain parental divorce. An additional six themes were developed around the types of stories children told of the divorce process. Themes included, What is a Divorcement, Stories of Loss, Stories of Gain, Stories of Change, Stories of Stability, Healing Stories, and Complicating Stories. This study endeavoured to provide divorced parents and those working with children a greater understanding of the way in which children perceive parental divorce, and insight into the factors that facilitate children’s positive adjustment to parental divorce.

Data for this study was obtained from eight South African newspapers and their websites. The study investigates whether the articles under review, including commentary and discussion online, focused on the incident itself or on the political landscape of South Africa. A content analysis was used to examine the data revelaling that Phooko was underrepresented and that most articles focused on Vavi’s political career. The research will use a feminist perspective to show that Phooko was under-represented in the media, in comparison to Vavi and his supporters who gained greater coverage, specifically in a political context. The significance of the findings is that although there are some strides achieved to have more women voices in the media however women are still under-represented.

- Description: Within the first decade of the ICC‟s existence, its case docket was composed of cases originating from Africa only. Relations between the African governments represented by the AU quickly deteriorated. The AU accuses the ICC of bias and unfair targeting of Africa. After the indictment of heads of states that include Omar Al Bashir of Sudan, Uhuru Kenyatta of Kenya and the late Muammar Gaddafi of Libya, the AU passed several resolutions where it reiterated its commitment to the rule of law and to combating impunity. The AU, however, instructed member states to cease all cooperation with the ICC. African states that are ICC members are now faced with conflicting obligations as a result of the AU resolutions. Moreover, the AU resolutions raise the spectre of a legitimacy crisis for the AU and a conflict between articles 27(2) and 98(1) of the Rome Statute. Based mostly on desk research coupled with my experience working on human rights and access to justice programmes in Sudan, South Sudan, Somaliland, Ethiopia, Kenya, Uganda and Zimbabwe, this thesis considers the possibility that the ICC is suffering from a legitimacy crisis as a result of the fall out and the issues of unfair selectivity that are raised by the AU. Employing the Third World Approaches to International Law as an analytical framework, the study attempts to reconcile the apparent contradictions in the new outlook and rhetoric of the AU pursuant to its Constitutive Act and the instruction to member states to withdraw cooperation with the ICC. The thesis also proposes practical ways to resolve the conflicting obligations caused by the AU resolutions and by operation of customary international law immunity of high ranking state officials referred to the ICC by way of a Security Council resolution. The current situation gives the ICC the appearance of a weak institution that is only good for low hanging fruit, which has a negative effect on the legitimacy of the ICC.

- Description: The kinetic and dosimetric features of the main thermoluminescent peak of synthetic quartz have been investigated in quartz ordinarily annealed at 500_C as well as quartz annealed at 500_C for 10 minutes. The main peak is found at 78 _C for the samples annealed at 500_C for 10 minutes irradiated to 10 Gy and heated at 1.0 _C/s. For the samples ordinarily annealed at 500_C the main peak is found at 106 _C after the sample has been irradiated to 30 Gy and heated at 5.0 _C/s. In these samples, the intensity of the main peak is enhanced with repetitive measurement whereas its maximum temperature is unaffected. The peak position of the main peak in the sample is independent of the irradiation dose and this, together with its fading characteristics, are consistent with first-order kinetics. For doses between 5 and 25 Gy, the dose response of the main peak of the annealed sample is superlinear. The half-life of the main TL peak of the annealed sample is about 1 h. The activation energy E of the main peak is around 0.90 eV. For a heating rate of 0.4 _C/s, its order of kinetics b derived from the whole curve method of analysis is 1.0. Following irradiation, preheating and illumination with 470 nm blue light, the main peak in the annealed sample is regenerated during heating. The resulting phototransferred peak occurs at the same temperature as the original peak and has similar kinetic and dosimetric features, with a half-life of about 1 h. For a preheat temperature of 200 _C, the intensity of the phototransferred peak in the sample increases with illumination time up to a maximum and decreases thereafter. At longer illumination times, no further decrease in the intensity of the phototransferred peak is observed. The traps associated with the 325 _C peak are the main source of the electrons responsible for the regenerated peak.

- Description: This treatise focuses on the design of a Water Sports Centre in the sporting precinct of Newlands in Cape Town. The building is concerned with the redevelopment of an existing facility that is underutilised and outdated, compared to the 21st-century sporting arena. The purpose of this treatise is to investigate the processes and issues involved in the design of a Water Sports Centre that is located in a public park environment, and to better understand the contextual, spatial, physical, and theoretical influences on the nature of such a project’s architectural resolution. The process begins with an analysis of the two separate typologies, namely, water sports centres and sports stadiums, to better understand the spatial and physical nature of the combined building types. Various precedents are investigated of which the materiality and physical nature of the buildings are uncovered to identify an appropriate architectural language. Moreover, the spatial nature of these buildings are divided into categories of which the inter-relationships are analysed. The nature of the site is then investigated to identify and develop constraints and design informants. The site-defining elements are analysed individually, and a corresponding set of issues is established through the study of particular precedents. With an understanding of the physical and spatial attributes of the typology, combined with an appropriate response to the site, the design resolution for the Water Sports Centre in the Newlands sporting precinct is presented.

- Description: The treatise focuses on how to design built space that is ‘place-specific’ and captures the ‘spirit’ of the Namib Desert landscape through the experience of architecture. The project specifically focuses on tourism developments in natural and cultural environments. An investigation and analysis are done of the nature of the physical, spatial and cultural context of the ephemeral Khuiseb river of Namibia. By inductive and deductive reasoning, an argument is presented regarding the appropriate architectural approach of a luxury eco-lodge in a proposed eco-tourism precinct, that captures the Zeitgeist of the context while responding to the socio-economic conditions to encourage an autonomous community in a selfsufficient and sustainable way.
