- Description: Vaccines have greatly contributed to the control of vaccine preventable diseases. The adoption of the Decade of Vaccines (DoV) by the World Health Assembly in 2011 is an indication of how the global community values the benefits of vaccines. Efforts by many countries to introduce new vaccines are a significant move towards attaining this vision. However, new vaccines put strain on vaccine supply chains. The immunization programme in South Africa has similar challenges, with indications of vaccine stock outs in clinics since the introduction of three new vaccines in 2009. This study set out to establish the status of availability of vaccines in Tshwane government clinics and associated factors. Method: A cross-sectional study was conducted in a sample of randomly selected government clinics in Tshwane health district of Gauteng province. Data was collected using a structured measurement instrument during a visit to each of the participating clinics. Data was collated and analysed using excel based software. Results: A total of 31 clinics participated. In the preceding 12 months, clinics experienced vaccine stock outs, especially of the 3 new vaccines: pneumococcal conjugate vaccine (PCV), rotavirus (RV) vaccine and Pentaxim ®. These were also out of stock for a long duration; for over 2 weeks in a majority of clinics. The causes of vaccine stock outs were: poor management of stock, depot out of stock, unreliable deliveries, lack of pharmacy assistants, and limited fridge capacity. Further burdening the situation is the emergency ordering system that does not function effectively. Conclusion: Significant vaccine shortages occur in Tshwane government clinics. It is recommended that the vaccine supply chain should be restructured and overhauled with the use of advances in technology. Urgent measures should be taken to address the identified causes of stock outs including ensuring reliable deliveries of stock and emergency orders.

- Description: This treatise discusses the increasing of the procedural and substantive limitations on the employees’ right to strike. The Constitution permits the right to strike to be limited in terms of the laws of general application. The Labour Relations Act (LRA) is a good example. Such limitation must be reasonable and justifiable in an open and democratic society, based on human dignity, equality and freedom. The study sought to investigate whether further increasing the existing limitations on the right to strike unduly breaches employees’ Constitutional right to strike and the purpose of the LRA. Further, the study sought to find out whether the additional content requirements in the strike notice amount to importing into the LRA additional limitations on the fundamental right to strike that enjoys no textual support. Through an extensive literature review, the findings arguably show that indeed further increasing the limitations on the employees’ right to strike may unduly infringe their right to strike. Moreover, the increase of the content requirements in a strike notice creates an unnecessary hurdle to employees wishing to strike. One of the most important finding made is that instead further increasing the limitations on the right to strike, going back to the basics of negotiation to alleviate strikes, particularly wage-related strikes is vital. To achieve this, it is important for employers to re-establish social and individual relationships with their employees, whereby they become aware of the issues that employees face on a daily basis. Also, establishing proper workplace dialogue and forums would assist employers in becoming aware of employees concerns. This would thereby prevent strikes, as problems can be dealt with beforehand. The findings above informed in the recommendations at the end of the study.

- Description: The important role played by small, medium and micro enterprises (SMMEs) in economic development has long been recognised by government at various levels in South Africa. The passing of the National Small Business Act, 1996 (Act 102 of 1996), and more significantly its Amendment Act of 2004 (Act 29 of 2004) which called into existence the Small Enterprise Development Agency (SEDA), as well as a range of strategies headed by the current Integrated Strategy on the Promotion of Entrepreneurship and Small Enterprises of 2005 bear testimony to a commitment on the part of the nation to small enterprise growth. There is vast research pertaining challenges facing small medium and micro enterprises (SMMEs) as well as factors that have a positive impact on the growth and success of these enterprises. This primary objective of this study was to identify successful SMMEs in the New Brighton Township, Port Elizabeth and investigate factors that have enabled them to maintain their stability over the years. Also, this study will investigated causes of SMME failure with the aim of providing possible solutions to these challenges. After a comprehensive literature review on SMMEs, the following variables were identified as possibly having an influence on the growth and profitability of small enterprises. These are: Entrepreneurial orientation; Customer focus; Human resources; Record keeping; Access to funding; External support; Training and education; Access to markets. These variables were used to construct research hypotheses and a conceptual model which could be used to address challenges faced by SMMEs.

- Description: The current study aimed at investigating the sustainability of KwaZakhele's Permaculture Project and was conducted in the Eastern Cape Province within the Nelson Mandela Metro Municipality at Ward 22 according to Municipal Ward demarcations. The researcher was motivated to carry out this study due to the fact that many food production projects in the NMMM are not sustainable and thus contribute to food insecurity and a high rate of unemployment. The purpose of this study was to investigate the potential of permaculture projects in solving some of the food insecurity and unemployment issues in the NMMM. The KwaZakhele Permaculture Project (KPP) is a vegetable garden which produces different types of vegetables for marketing purposes and for household consumption. The KPP is supported financially by overseas-based organisations and have created ten direct work opportunities for KwaZakhele community. All the project members of the KPP are women. A qualitative research approach was employed in this study, with the emphasis of collecting primary data from the project participants as well as consulting secondary data from sources such as academic journals, books and government policy documents. The study reveals that permaculture design training and project monitoring are the most important developmental support permaculture projects need before and after implementation. The study also determined that the costs of establishing permaculture project can be higher or lower depending on the project size. Consultation and co-ordination fees account for a greater portion of the funding followed by permaculture infrastructure. The results of the study also indicate that permaculture design principles and ethics are seen as a strength for the sustainability of KPP.

- Description: This investigation focussed on the inclusion and resolution ability of (2R,3R)-1,1,4,4-tetraphenylbutane-1,2,3,4-tetraol (TETROL), studies on the stoichiometry of its derivatives and the formation of inclusion compounds for single crystal analysis. The guest compounds that featured in the main study were cyclohexanone, 2-methylcyclohexanone, 3-methylcyclohexanone and 4-methylcyclohexanone. It was found that 3- and 4-methylcyclohexanone were trapped in their energetically unfavourable axial conformations in the inclusion crystal. Resolution experiments proved that (2R,3R)-1,1,4,4-tetraphenylbutane-1,2,3,4-tetraol can be used as a resolving agent for 2- and 3-methylcyclohexanone, with ee values of 13% and 22%, respectively (according to the method of Hiemstra), in favour of the R-enantiomer. Single crystal X-ray diffraction (SCXRD) studies, however, showed that 2-methylcyclohexanone was resolved with an ee of 30% in R. An ee of 56% in R was obtained for 3-methylcyclohexanone. Enantiomer enrichment of 2-methylcyclohexanone was achieved in basic medium (ee of 18% according to the method of Hiemstra) and showed that by using the host in either half or double the molar ratio of the guest, a higher ee was obtained than for a 1:1 ratio. The following TETROL derivatives were also synthesized and their stoichiometries with various guest compounds were determined: (2R,3R)-1,1,4,4-tetra(naphthalen-1-yl)butane-1,2,3,4-tetraol; (2R,3R)-1,1,4,4-tetra(naphthalen-2-yl)butane-1,2,3,4-tetraol; (2R,3R)-1,1,4,4-tetra(p-anisyl)butane-1,2,3,4-tetraol; (2R,3R)-1,1,4,4-tetra(p-tolyl)butane-1,2,3,4-tetraol; (2R,3R)-1,1,4,4-tetra(m-tolyl)butane-1,2,3,4-tetraol and; (2R,3R)-1,1,4,4-tetra(o-tolyl)butane-1,2,3,4-tetraol.

- Description: The sale of an entity as a going concern has a number of tax consequences for both the purchaser and the seller. The tax deductibility of a contingent liability upon its transfer from the seller to the purchaser, where the selling price has been reduced by the value of the contingent liabilities transferred, remains uncertain following the decision in Ackermans Ltd v Commissioner for the South African Revenue Service. An expense is either deductible under a specific section of the Income Tax Act, 58 of 1962, or under the general expense provisions in terms of sections 11(a) and 23(g). The Act does not contain a specific section relating to contingent liabilities and therefore a contingent liability will need to be considered for deduction under these sections. The Act further disallows an expense as a deduction under section 23(e), where a reserve is created (for example a leave pay provision). This study analyses the tax deductibility of a contingent liability, where the contingent liability has been transferred from the seller to the purchaser in a sale of an entity as a going concern and the purchase price has been reduced to compensate for the transfer of the contingent liability. The deductibility of the contingent liability was first assessed in terms of the provisions of the Act (sections 11(a), 23(g) and 23(e)) and associated case law. The decision in the Ackermans case and its preceding Income Tax Case 1839 was then analysed in order to establish the principles arising from the decisions. Finally the proposals in the Draft Taxation Laws Amendment Bill, 2011, and the subsequent Discussion Document issued by the South African Revenue Service were discussed. The analysis revealed the continuing confusion surrounding the status quo, thus demonstrating the importance of legislative intervention to provide guidelines for taxpayers.

- Description: Recent studies have shown that graduates from historically White universities (HWUs) experience better labour market outcomes than graduates from historically Black universities (HBUs). This is a result of the legacy of apartheid which promoted racial inequality in all spheres of South African society, more especially in higher education and the labour market. Post-1994, government dedicated large amounts for the restructuring of the higher education sector of South Africa in order to level out the playing field. However, graduates from HWUs still experience better labour market success than graduates from HBUs. That said, there is limited information about the labour market outcomes and experiences of graduates from a former White university (especially graduates from Rhodes University). Therefore, the central aim of this dissertation is to show that graduates from a historically White university (Rhodes University) experience varying and unequal outcomes in the South African labour market on account of (among other factors) their chosen fields of study, race and sex. This study is informed by the heterodox labour market approach, which is partly inspired by the critical realist account of the labour market. As a result, this theoretical framework allowed the researcher to use the Labour Market Segmentation (LMS) theory as a tool to inform this analysis. The study has adopted a quantitative survey design and has incorporated some of the key methodological lessons learned from the collection of international graduate tracer studies. The findings from this study indicated that ‘field of study’ is a strong determiner of the outcomes of Rhodes graduates in the labour market. This was visible in the persistence of a skills bias towards commerce and science graduates. Evidently, even when we controlled for race and sex, graduates from the commerce and science faculties experience better labour market outcomes than humanities graduates. This is a result of a skills biased South African economy, which has a higher demand for certain skills over others. However, the findings from this study also show evidence of pre-labour market discrimination and inequality (based on race and sex) in the supply-side institutions such as the family, schooling and university. The findings also show continuities and discontinuities of labour market discrimination (based on race and sex) in the outcomes of Rhodes graduates in the South African labour market. More importantly, this dissertation indicates that Rhodes graduates experience varying outcomes in the labour market as a result of (among other factors) their chosen fields of study, race and sex.

The trophic ecology of the endangered endemic Barau's Petrel (Pterodroma baraui) from Reunion Island, south-western Indian Ocean

- Description: Réunion is the only tropical island that supports two endemic gadfly petrels. Population modelling has indicated that the current threats to the Barau’s Petrel (Pterodroma baraui) may drive it to extinction; this fate is almost definite for the Mascarene Petrel (Pseudobulweria aterrima). Management interventions have therefore been implemented, but conservation potential is handicapped since virtually nothing is known about the former species’ at-sea biology. Thus, following numerous recommendations, this study aimed to combine stomach content, stable isotope, and fatty acid analyses so to provide new information on the at-sea ecology of Barau’s Petrel. Breeding colonies were repeatedly visited over the same season and samples gathered from adults, fledglings, and downy chicks. Stomach contents consisted mostly of accumulated cephalopod beaks whereas structures from fishes, molluscs, arthropods, and crustaceans were less frequently encountered. Fatty acid profiles of blood varied greatly among individuals and the lowincidences of monounsaturated and n-3 fatty acids discounted fish as an important dietary component. δ¹⁵N of blood indicated a niche between the fourth and fifth trophic levels, which proposes that these birds scavenge to a greater degree than other sympatric seabirds and suggests that adults are also reliant on their endogenous reserves during breeding. δ¹³C values confirmed the migratory behaviour of adults since birds returning from the non-breeding grounds were enriched relative to individuals sampled through the breeding period. Significant intra-breeding season variations in δ13C were also observed, which matched this species’ patterns of habitat use as have recently described. These results collectively indicate an opportunistic behaviour, which implies some degree of resilience against shifts in prey availability/accessibility, and suggest that this species’ reproduction isdependent on distant foraging areas. This breeding strategy is synonymous with great vulnerability as over-investing into a single breeding episode may jeopardize future survival and fecundity. Thus, in light of environmental conditions that are becoming increasingly more susceptible to dramatic changes, the birds could rather be prioritising adult survival, over reproductive output. Further work is obviously necessary and should benefit from databases of fatty acid profiles and isotope signatures of potential prey species.

- Description: Réunion is the only tropical island that supports two endemic gadfly petrels. Population modelling has indicated that the current threats to the Barau’s Petrel (Pterodroma baraui) may drive it to extinction; this fate is almost definite for the Mascarene Petrel (Pseudobulweria aterrima). Management interventions have therefore been implemented, but conservation potential is handicapped since virtually nothing is known about the former species’ at-sea biology. Thus, following numerous recommendations, this study aimed to combine stomach content, stable isotope, and fatty acid analyses so to provide new information on the at-sea ecology of Barau’s Petrel. Breeding colonies were repeatedly visited over the same season and samples gathered from adults, fledglings, and downy chicks. Stomach contents consisted mostly of accumulated cephalopod beaks whereas structures from fishes, molluscs, arthropods, and crustaceans were less frequently encountered. Fatty acid profiles of blood varied greatly among individuals and the lowincidences of monounsaturated and n-3 fatty acids discounted fish as an important dietary component. δ¹⁵N of blood indicated a niche between the fourth and fifth trophic levels, which proposes that these birds scavenge to a greater degree than other sympatric seabirds and suggests that adults are also reliant on their endogenous reserves during breeding. δ¹³C values confirmed the migratory behaviour of adults since birds returning from the non-breeding grounds were enriched relative to individuals sampled through the breeding period. Significant intra-breeding season variations in δ13C were also observed, which matched this species’ patterns of habitat use as have recently described. These results collectively indicate an opportunistic behaviour, which implies some degree of resilience against shifts in prey availability/accessibility, and suggest that this species’ reproduction isdependent on distant foraging areas. This breeding strategy is synonymous with great vulnerability as over-investing into a single breeding episode may jeopardize future survival and fecundity. Thus, in light of environmental conditions that are becoming increasingly more susceptible to dramatic changes, the birds could rather be prioritising adult survival, over reproductive output. Further work is obviously necessary and should benefit from databases of fatty acid profiles and isotope signatures of potential prey species.

- Description: The meaning of the term “benefits” in the context of unfair labour practice jurisprudence, having previously been unsettled for more than a decade, has now been settled by the Labour Appeal Court in the Apollo.1 Prior to Apollo,2 our courts have struggled to adopt a stance to maintain the distinction between disputes of rights and disputes of interest as separate compartments. The prevalent view at that stage was that, in order for an employee to lodge a dispute at the CCMA or Bargaining Council the employee would have to show that he or she had a right to the benefit that arises by virtue of contract, statute or collective agreement, failing which the CCMA or a Bargaining Council would not have the jurisdiction to determine the dispute, in which case it may constitute a dispute of interest and the employee will have to embark on an industrial action to secure a benefit. Apollo3 endorsed a previous decision of the Labour Court,4 i.e. by placing “benefits” into the following two categories: (1) Where the dispute is about a demand by employees concerning their benefits, it can be settled by way of industrial action. (2) Where the dispute concerns the fairness of the employer's conduct, it must be settled by way of adjudication or arbitration. As a result of the above categorisation, the CCMA or Bargaining Council may adjudicate a dispute relating to benefits where there is a pre-existing benefit and the employer refuses to comply with its obligation towards the employer in that regard. It may also adjudicate disputes relating to the provision of a car allowance (i.e. where the employer retains the discretion to grant or withhold the allowance) and disputes relating to the provision of bonuses (i.e. where the employer retains the discretion to grant or withhold the bonus). In this treatise, I set out the history and development of the legislation in relation to the concept of “benefits” (in the context of unfair labour practice) so as to understand how our Labour Appeal Court has now come to settle the issues above.

- Description: Organisations worldwide are attempting to identify talent by using various assessment methods to evaluate competencies perceived to be core to the mandate of their organisations. In recent years recruitment and selection of individuals rely on assessment methods deemed to have high validity and reliability. One such assessment method used worldwide to evaluate top management is the assessment centre, commonly referred to as the AC. The main research problem of this study focussed on an evaluation of the extent to which the assessment centre method is effectively used for the selection and development of senior management employees in the public service of Botswana. The main research problem had eight sub-problems which were addressed through the following actions: A comprehensive literature study was conducted to define and establish the purpose of assessment centres. Moreover, the study aimed to establish the international best practice for the administration of the assessment centre as a tool for selection and talent development. Subsequent to the literature study an interview schedule and survey questionnaire were developed based on the literature. The interview schedule was used to obtain information from consultants who provide assessment centre services to the public service. The objective of the questionnaire was to obtain information from the recipients of the service and determine the extent to which that information compares with information obtained from the consultants. The questionnaire was distributed to a randomly selected population. The results of the empirical study were statistically analysed and interpreted and revealed that permanent and deputy permanent secretaries are more aware of the reasons for using the assessment centre method than directors and deputy directors. These senior management employees felt that the assessment centre is an effective tool for selection and development but the results from the assessment centre are not optimally used for development. The study revealed that generally the assessment centre process conducted in the Botswana public service is in line with international best practice of assessment centres. However, there are certain areas that need some improvement for the assessment centre to entirely conform to international best practice. These areas include the implementation of an assessment centre policy and the improvement of feedback and vital information provided to participants prior to the centre. The empirical study also revealed that senior management employees hold the view that many senior officers in the public service do not know the importance of the assessment centre method and are not comfortable to participate in such a centre. The assessment centre method has proven to be an effective tool for evaluating competencies. This is due to its use of multiple techniques, assessors, simulations and exercises. Theory has revealed that the assessment centre has higher validity and reliability than other assessment methods. However, due to the high costs of running assessment centres, some organisations take shortcuts and therefore jeopardise its validity.

- Description: Physiological stress in farmed abalone can lead to immunosuppression and increase the susceptibility to bacterial, viral and parasitic disease, often followed by mortality. Thus, handling and poor water quality can reduce farm production efficiency. Probiotics in aquaculture have been effective in a wide range of species in enhancing immunity, survival, improving feed utilisation and growth. Three putative probionts identified as a result of in vitro screening had been beneficial to laboratory-reared abalone in a previous study. The aim of this study was to produce an abalone feed that contains a suite of probionts that may promote abalone growth and health under farming conditions. The objectives were to compare growth and physiological responses (i.e., haemocyte and phagocytosis counts) of abalone fed a commercial feed (Abfeed®S 34, Marifeed, Hermanus) supplemented with probiotics (i.e., the probiotic diet) to abalone fed the commercial feed without probiotic supplementation as a control treatment in a factorial design with handling method as an independent variable. This experiment was conducted at HIK Abalone Farm (Pty Ltd) for a period of eight months with initial weight and length 36.1 ± 0.05 g and 58.6 ± 0.06 mm abalone-1. Another experiment was carried out at Roman Bay Sea Farm (Pty) Ltd with initial weight and length 34.7 ± 0.17 g and 62.3 ± 0.18 mm abalone-1, but this experiment included one factor only, i.e. the presence and absence of the probionts in the feed. At HIK there was no significant interaction between diet and handling on average length and weight gain month-1 after four (p=0.81 and p=0.32) and eight (p=0.51 and p=0.53) months, respectively. Average length (additional handling = 73.9 ± 0.52 mm, normal farm handling = 75.8 ± 0.57 mm) and weight gain (mean: additional handling = 68.5 ± 1.20 g, normal farm handling = 74.3 ± 1.86 g) increased significantly in animals that were handled under normal farm procedure and were either fed probiotic or control diet after eight months (p=0.03 and p=0.02, respectively). There was no iii difference in length gain or weight gain of abalone fed the probiotic diet and those fed the control diet (ANOVA: F(1,16)=0.04, p=0.84; F(1,16)=0.14, p=0.71, respectively). After four months phagocytotic count was significantly different between dietary treatments with mean values of 74.50 ± 10.52 and 63.52 ± 14.52 % phagocytosis count per sample for the probionts and control treatment, respectively (p=0.04), there was no difference after eight months at HIK Abalone Farm. There was no effect of stressor application (p=0.14) and no interaction between dietary treatment and stressor application for this variable i.e., phagocytosis count (p=0.61). There was no difference in feed conversion ratio between treatments with values ranging from 2.9 to 3.8. At Roman Bay Sea farm, there was no significant difference in mean length gain between abalone fed the probiotic and control diet after eight months (repeated measures ANOVA: F(4,28)=16.54. Mean weight gain of abalone fed the probiotic diet was significantly greater than those fed the control diet after eight months (repeated measures ANOVA: F(4,28)=39.82, p(0.00001). There was no significant difference in haemocyte counts between animals fed either probiotic or control diet after four and eight months at Roman Bay Sea farm (p>0.05).

- Description: This study of 449 newspaper articles from South Africa from 1997 provides an analysis of the representations of obesity evinced in the corpus. The research argues that obesity is overwhelmingly framed as being diseased and that there are four main refrains within this frame, namely, statistics on obesity, the naturalisation of negative assumptions about fat, the social dysfunction of fat and the use of crisis metaphors to describe fatness. This framing lends itself to representations of obesity which are raced, gendered and classed. Fat bodies are portrayed as being in deficit and fat people as lacking agency. The disproportional focus on black bodies in the corpus can be attributed to assumptions of ‘incivility’ which are premised on racial stereotypes which construct black people as being unintelligent, irrational, lacking agency and being largely dependent on others to survive. This disproportional focus on black bodies can also be understood in the context of emerging markets. This study argues that the medicalisation of obesity has contributed to many oversimplifications and contradictions in the representation of obesity in the corpus, which seem to go unquestioned, such as the conflation of weight and health, something I argue is one of the main contributors to the negative consequences of the dominant framing of obesity. Framing obesity as medicalised also promotes fat shaming and acts as a form of social control which maintains existing power relations through the use of discursive practices for the identification and control of deviants. These representations are problematic chiefly because they promote the dehumanisation of fat people, but also because that they do not promote good health as they claim to do.

- Description: This thesis developed out of a concern for the ecological biodiversity of natural environments and the way in which human interventions place constant and increasing pressure on them. Modern cities have generally placed little concern on the overall well-being of these systems which all flora and fauna depend upon. This causes stress on many species, with some ending in extinction. The Knysna Seahorse (Hippocampus capensis) is one such species which has suffered because of irresponsible city development. It is a small and seemingly irrelevant animal to many, but its well-being is a far greater issue than that of the tiny endangered creature. It acts as an indicator species of a threatened environment. This treatise takes a critical look at developing an awareness among people of the importance of the ecological well-being of nature alongside the cities of South Africa. More specifically it focuses on the secret and vulnerable lives of the endangered and endemic Knysna Seahorse within its threatened natural environment. The issues facing the natural environment of Knysna will be looked at in depth and sets of interventions will be proposed to minimise further anthropocentric effects on nature. The first part of the proposal will be a larger scale urban intervention that will set the framework for the treatise building design. It has been proposed to design a Research Aquarium for the Knysna Seahorse (H. capensis) as an active ecological research, conservation and education centre. The buildings activities will aid in public education and raise a place specific awareness of the Knysna Estuary and its endangered seahorse species through its conservation efforts. The Seahorse Research Aquarium is to be positioned within a new vision of a waterfront for the Knysna Central. The Research Aquarium will seek to become a mediator between man’s urban environment and the ecological systems of nature. This can be realised as part of a promotion for an enhanced connection of Knysna’s urban environment to that of the natural environment. Ultimately a positive shift in the way in which people respond to the well-being of the environment will be created. The research conducted will focus on the particular interaction between the man-made urban environments within Knysna and the natural environment. The resulting urban and architectural strategies implemented will allow for an empathetic and balanced relationship between man and nature. This harmonious coexistence is essential for the sustenance of the unique natural environments that South Africa should cherish (GNTO .2013). Promoting a healthy and vibrant natural ecology within an urban environment will enhance the quality of life of both man and nature.

Through the Burtonesque looking-glass : interrogating the psychoanalytic in Tim Burton's adaptation of selected children's texts

- Description: The primary aim of this thesis is to interrogate existing psychoanalytical theory, as well as to conduct research on ‘the Burtonesque’ in order to examine two of Tim Burton's filmic adaptations of classic literary works for children, namely: Alice in Wonderland (2010), an adaptation inspired by Lewis Carroll's Alice books, and Charlie and the Chocolate Factory (2005), based on Roald Dahl's novel of the same title. Firstly, the chapters will explore the psychological elements found in the original texts, which Burton amplifies in his onscreen adaptations by means of various stylistic and thematic techniques that have become known as ‘the Burtonesque’. Secondly, the ‘Burtonesque’ itself will be explored, and thirdly, by means of comparative analysis, the investigation will focus on the manner in which such aesthetics aid Burton in highlighting psychological concerns in his films, as well as interrogate his cinematic alterations to existing texts in order to further his purpose. As a keen enthusiast of psychology and having won awards within the field, Tim Burton, a foremost contemporary Hollywood filmmaker, in his adaptations of children’s classics, deliberately magnifies the psychoanalytic components that are often found in the tales. Through his unique interpretation, Burton brings the psychoanalytic approach to children’s stories to a new level. He explores certain themes such as death, childhood fantasies, psychological development and parental relationships, and makes use of specific artistic techniques that create a sense of the uncanny and defamiliarisation in the viewer. Due to his gothic cinematic approach, Burton is one of the most recognisable artists in his field, with a consistent vision that is concerned with cinematic and thematic aspects of his work, branding his films with a unique ‘Burtonesque’ quality that has become instantly identifiable. As a result of Burton’s psychological interest in children’s stories, Tim Burton’s film adaptations of the Dahl and Carroll classic children’s stories can be interrogated under a psychoanalytic lens. Psychoanalytic literary criticism is a method of literary analysis that is informed by the tradition of psychoanalysis established by Freud. In Burton scholarship, critical exploration should take the form of not only a close reading of the original text and analysis of the film version in order to come to a psychoanalytic interpretation, but by means of comparison of film and text, highlight the methods applied by psychoanalytic theory. A close comparative analysis of original literary works by Roald Dahl and Lewis Carroll, and Tim Burton’s filmic adaptations will be conducted in this study.

- Description: The primary aim of this thesis is to interrogate existing psychoanalytical theory, as well as to conduct research on ‘the Burtonesque’ in order to examine two of Tim Burton's filmic adaptations of classic literary works for children, namely: Alice in Wonderland (2010), an adaptation inspired by Lewis Carroll's Alice books, and Charlie and the Chocolate Factory (2005), based on Roald Dahl's novel of the same title. Firstly, the chapters will explore the psychological elements found in the original texts, which Burton amplifies in his onscreen adaptations by means of various stylistic and thematic techniques that have become known as ‘the Burtonesque’. Secondly, the ‘Burtonesque’ itself will be explored, and thirdly, by means of comparative analysis, the investigation will focus on the manner in which such aesthetics aid Burton in highlighting psychological concerns in his films, as well as interrogate his cinematic alterations to existing texts in order to further his purpose. As a keen enthusiast of psychology and having won awards within the field, Tim Burton, a foremost contemporary Hollywood filmmaker, in his adaptations of children’s classics, deliberately magnifies the psychoanalytic components that are often found in the tales. Through his unique interpretation, Burton brings the psychoanalytic approach to children’s stories to a new level. He explores certain themes such as death, childhood fantasies, psychological development and parental relationships, and makes use of specific artistic techniques that create a sense of the uncanny and defamiliarisation in the viewer. Due to his gothic cinematic approach, Burton is one of the most recognisable artists in his field, with a consistent vision that is concerned with cinematic and thematic aspects of his work, branding his films with a unique ‘Burtonesque’ quality that has become instantly identifiable. As a result of Burton’s psychological interest in children’s stories, Tim Burton’s film adaptations of the Dahl and Carroll classic children’s stories can be interrogated under a psychoanalytic lens. Psychoanalytic literary criticism is a method of literary analysis that is informed by the tradition of psychoanalysis established by Freud. In Burton scholarship, critical exploration should take the form of not only a close reading of the original text and analysis of the film version in order to come to a psychoanalytic interpretation, but by means of comparison of film and text, highlight the methods applied by psychoanalytic theory. A close comparative analysis of original literary works by Roald Dahl and Lewis Carroll, and Tim Burton’s filmic adaptations will be conducted in this study. Thereby, the manner in which Tim Burton employs specific techniques in order to emphasise the stories’ psychological components will be explored. Biographical information of Dahl and Lewis, as well as a short synopsis of their stories will be included in order to provide the context for psychoanalytical criticism.

- Description: My study explores the politics of viewing and the gaze. I argue that the gaze both arrests and objectifies the body, which in turn transforms subjects into objects therefore regulating social behaviour. The basic notion of the gaze will be explored throughout this thesis and thereby contextualizes my sculptures, which are casts of my naked body. My particular concern lies in how the ideas of surveillance have had an influence on architecture and buildings in Grahamstown. Throughout this mini thesis, I will explore a number of architectural spaces of Grahamstown such as the Provost prison, Fort Selwyn and the Camera Obscura which I argue were all designed based on the ideas of surveillance. The entanglement of Grahamstown architecture and the female form as a subject of voyeurism forms an important part of this thesis, as the context of Grahamstown architecture is centered on visibility, which in turn subjects people to a form of discipline. The Provost Prison, the Camera Obscura and the forts of Grahamstown are all good examples of this. Outside of this, the female body is also subjected to the gaze, which in turn suggests that the female body is also under surveillance and as a result also becomes disciplined. My installation is a response to Antony Gormley’s Event Horizon, in which he placed 33 steel and fibreglass casts of his own naked body at an elevated level on buildings around Manhattan and Brazil. In this discussion I have contextualized my work with reference to the ideas of different theorists. The three main theorists I have cited are Michel Foucault, Jonathan Crary and Laura Mulvey. Foucault is specifically cited due to his discussion on Panoptic power, surveillance and docile bodies. Crary makes a number of important points with regards to the ideological operations of the Camera Obscura as well as its history while Laura Mulvey’s writings form the basis of the voyeuristic gaze from the perspective of a feminist.

- Description: Tillage operations disrupt the soil structure resulting in aggregates of various sizes and altered bulk density. Moreover, tillage influences soil carbon pools and many other soil physical properties. The objectives of this study were to determine, in various South African soils under different tillage systems, the following. (1) Amount of aggregate-associated soil organic carbon (SOC), (2) soil compressibility, and (3) relationship between compressibility, texture and the aggregate-associated SOC. The soil samples used in this study were collected from six different sites in Eastern Cape Province, South Africa. Soil samples were taken from conventional tillage (CT) and no-till (NT) land. To keep the soil aggregates intact sampling was done using a spade and carefully carried to the laboratory in rigid containers. For SOC determination, treatments were the two tillage systems, CT and NT, and four aggregate sizes. The experimental design was completely randomized design with a factorial layout and was replicated three times. Aggregate-associated SOC was determined using Walkley-Black method. Proctor compaction test was used determine the dry bulk density with varying moisture content and consequently the maximum bulk density (MBD) and critical water content (CWC). The aggregate-associated SOC content differed with tillage system and was significant higher (p < 0.05) in CT than NT. The amount of aggregate-associated SOC was 1.67 times higher in CT than NT plots. The MBD ranged between 1.77 g/cm3 and 10.27 g/cm3 and the CWC ranged from 9.1 percent to 10.3 percent. The higher amounts of SOC in CT were attributed to the annual crop residue returns while the lower amounts of SOC in the NT fields were due to grazing. Therefore, tillage influenced the amount of aggregate-associated organic carbon irrespective of the resulting size of the aggregate. The positive relationship between tillage and aggregate-associated SOC challenges the conversion of land to no-till for carbon sequestration. The overall gradient for correlation between the MBD and CWC was negative with r2 = 0.23 and a p value of 0.0076. The compressibility curves indicated higher values under CT if the texture class was silt clay.

- Description: The effectiveness of implementing field programmable gate arrays (FPGAs) in communication, military, space and high radiation environment applications, coupled with the increased accessibility of private individuals and researchers to launch satellites, has led to an increased interest in commercial off the shelf components. The metal oxide semiconductor (MOS) structures of FPGAs however, are sensitive to radiation effects which can lead to decreased reliability of the device. In order to successfully implement a FPGA based system in a radiation environment, such as on-board a satellite, the single event upset (SEU) and total ionizing dose (TID) characteristics of the device must first be established. This research experimentally determines a research procedure which could accurately determine the SEU cross sections and TID characteristics of various mitigation techniques as well as control circuits implemented in a ProASIC3 A3P1000 FPGA. To gain an understanding of the SEU effects of the implemented circuits, the test FPGA was irradiated by a 66MeV proton beam at the iTemba LABS facility. Through means of irradiation, the SEU cross section of various communication, motor control and mitigation schemes circuits, induced by high energy proton strikes was investigated. The implementation of a full global triple modular redundancy (TMR) and a combination of TMR and a AND-OR multiplexer filter was found to most effectively mitigate SEUs in comparison to the other techniques. When comparing the communication and motor control circuits, the high frequency I2C and SPI circuits experienced a higher number of upsets when compared to a low frequency servo motor control circuit. To gain a better understanding of the absorbed dose effects, experimental TID testing was conducted by irradiating the test FPGA with a cobalt-60 (Co-60) source. An accumulated absorbed dose resulted in the fluctuation of the device supply current and operating voltages as well as resulted in output errors. The TMR and TMR filtering combination mitigation techniques again were found to be the most effective methods of mitigation.

- Description: In this thesis a framework for Security Operation Centers (SOCs) is proposed. It was developed by utilising Systems Engineering best practices, combined with industry-accepted standards and frameworks, such as the TM Forum’s eTOM framework, CoBIT, ITIL, and ISO/IEC 27002:2005. This framework encompasses the design considerations, the operational considerations and the means to measure the effectiveness and efficiency of SOCs. The intent is to provide guidance to consumers on how to compare and measure the capabilities of SOCs provided by disparate service providers, and to provide service providers (internal and external) a framework to use when building and improving their offerings. The importance of providing a consistent, measureable and guaranteed service to customers is becoming more important, as there is an increased focus on holistic management of security. This has in turn resulted in an increased number of both internal and managed service provider solutions. While some frameworks exist for designing, building and operating specific security technologies used within SOCs, we did not find any comprehensive framework for designing, building and managing SOCs. Consequently, consumers of SOCs do not enjoy a constant experience from vendors, and may experience inconsistent services from geographically dispersed offerings provided by the same vendor.

- Description: Critical Infrastructure is often overlooked from an Information Security perspective as being of high importance to protect which may result in Critical Infrastructure being at risk to Cyber related attacks with potential dire consequences. Furthermore, what is considered Critical Infrastructure is often a complex discussion, with varying opinions across audiences. Traditional Critical Infrastructure included power stations, water, sewage pump stations, gas pipe lines, power grids and a new entrant, the “internet of things”. This list is not complete and a constant challenge exists in identifying Critical Infrastructure and its interdependencies. The purpose of this research is to highlight the importance of protecting Critical Infrastructure as well as proposing a high level framework aiding in the identification and securing of Critical Infrastructure. To achieve this, key case studies involving Cyber crime and Cyber warfare, as well as the identification of attack vectors and impact on against Critical Infrastructure (as applicable to Critical Infrastructure where possible), were identified and discussed. Furthermore industry related material was researched as to identify key controls that would aid in protecting Critical Infrastructure. The identification of initiatives that countries were pursuing, that would aid in the protection of Critical Infrastructure, were identified and discussed. Research was conducted into the various standards, frameworks and methodologies available to aid in the identification, remediation and ultimately the protection of Critical Infrastructure. A key output of the research was the development of a hybrid approach to identifying Critical Infrastructure, associated vulnerabilities and an approach for remediation with specific metrics (based on the research performed). The conclusion based on the research is that there is often a need and a requirement to identify and protect Critical Infrastructure however this is usually initiated or driven by non-owners of Critical Infrastructure (Governments, governing bodies, standards bodies and security consultants). Furthermore where there are active initiative by owners very often the suggested approaches are very high level in nature with little direct guidance available for very immature environments.
