Description: The Wild Coast of the Eastern Cape is renowned for its cultural landscapes, stunning scenery and remarkable biodiversity. It is also one of the least developed regions of South Africa, which underpins the small productive base and limited economic opportunities for the hundreds of rural communities scattered along the hilltops. It is not surprising therefore, that many inhabitants make extensive use of natural resources, such as firewood, reed mats, medicinal plants and wild vegetables, in their daily lives, as well as for sources of income when the opportunity arises.

Description: Despite the intentions of government and commitments by its social partners, South Africa continues to experience one of the highest levels of income inequality in the world and almost half of its households live below the minimum living level used by the National Planning Commission. Persistent calls for deregulation and lower wages to encourage job creation have been countered by arguments that the depth of income poverty and the extent of income inequality require consolidation and deepening of gains made by working people since 1994 and as expected in terms of international commitment to the International Labour Organisation’s (ILO’s) Decent Work Agenda. It is in this context that we undertake a closer examination of the shifts in the patterns of working poverty over the period 1997-2012. Challenges in calculating the rate of working poverty include defining the poverty line(s) to be used, and linking data on household incomes and individual employment status. We analyse data collected by Statistics South Africa through its October Household Surveys in 1997-1999 and General Household Surveys in 2004-2012, to examine trends in the rates of working poverty at various poverty lines, as well as trends in respect of employment amongst the poor, the depth of poverty, sources of income, and selected aspects of household composition. Our analysis shows that although the rate of working poverty decreased during the period under examination, 14% of workers still lived in households below the lower bound official poverty line, more than a fifth lived below the upper bound official poverty line, and more than a third of workers lived in households with just enough income to cover the minimum of their most basic needs. The poverty gap decreased for the working poor and for the poor in general, with the expansion of social grants in the early 2000s playing a role. We find that changes in the labour market over the post-apartheid period have not added appreciably to the demonstrable income effects achieved through the expansion of the social grant system. The implications of these findings for labour market regulation and social policy are briefly considered.

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.

Description: The extracts which we print and annotate below are from eight diaries formerly in the possession of the National English Literary Museum (NELM) and written by Olive Schreiner's husband, Samuel Cronwright, from 7 June 1921 to 13 May 1926. They are described in detail by Guy Butler on pages 16 and 17 of Walters and Fogg, Olive Schreiner: Her Reinterment on Buffelskop, which itself derives almost wholly from Diary 1. As we worked our way through these diaries, it seemed a pity not to publish - for the benefit of Schreiner scholars and enthusiasts - the many references to Schreiner and Cronwright's relationship with her which are scattered through their pages. As these diaries - together with the whole Cronwright collection which Cronwright originally left with his brother in Grahamstown when the latter was Manager of the EP Guardian, Loan and Investment Company - have now been removed from NELM's care by Cronwright's grandson (presumably for sale and disposal elsewhere), the publication of these fragments is perhaps of greater importance than when this project was originally undertaken in 2007.

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. 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. A discussion of ‘the Burtonesque’ will be provided, as well as a brief exploration of his adaptation history and Burton’s specific interest in psychology. Research methods to be applied in the analysis of the original texts and their film versions are psychoanalytic literary theory, drawing predominantly on the work of theorists: Sigmund Freud, Jacques Lacan and Carl Jung. A close examination of auteur theory, the unique voice Burton has established through his iconic cinematic techniques, now coined ‘the Burtonesque’, will also be applied to provide a fuller and rounder interrogation. The focus of this project is to investigate thempsychoanalytical elements found in the texts and films, in order to clearly illustrate how Tim Burton’s cinematic approach serves to highlight a psychoanalytic interpretation.

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.

Towards a changing context and performance practice of mbira dzavadzimu music in Zimbabwe

Description: Mbira dzavadzimu music and performance practice has been in existence since the pre-colonial era. It played a crucial role in ritual and non-ritual activities of the Shona people of Zimbabwe. However, political, social and global influences as well as technological advancement have resulted in change of context and performance practice. Unfortunately, these have not been recorded for future generations. The major aim of the study is therefore to examine the change of context and performance practice of mbira dzavadzimu in Zimbabwe. This was achieved by reviewing mbira dzavadzimu music and performance practice within the modern setting of dandaro. I looked at change from a theoretical lens of the theory of diffusion, syncretism and mediatisation. The study was in the qualitative form superimposed on some case studies. Unstructured interviews, participant and non-participant observations were the main instruments used to collect data from both traditional and modern mbira performances. Data was also collected from museums, archives, radio and television stations. The study established that the changes in context and performance practice of mbira dzavadzimu in Zimbabwe were to a larger extent due to foreign influences such as colonialism, the coming of missionaries, modernisation, urbanisation, commercialisation, mediatisation, the use of modern technology and institutionalisation. Due to the aforementioned influences, the environmental settings, the change of context from sacred to secular, the relationship with ancestral spirits, musical practices, performance situations and quality of sound, have been modified and adjusted in response to the influences of the globalised world’s ever changing audience and performance space. In short, this has resulted in a shift of mbira performances from its traditional to modern settings, from the village to the city and onto the international scene with a new performer-audience setting. Various innovations were carried out on the instrument and its music as a result of the advent of modern technology. The use of microphones, modern amplification systems, recording studios, radio and television broadcast, audio and video cassettes, CDs, DVD, teaching of the instrument using audio and video instructional models and the use of internet sites in learning how to play mbira dzavadzimu and other instruments have become a reality. It has been evident from the study that urban and rural areas take up change in different ways and that in the former change is more pronounced than in the latter. Urban area communities are more “developed” than their rural counterparts because the former are more exposed to technological influences and the commercialisation of music. The study has also established that Zimbabwean mbira music is a good example of modern transculturality. The instrument and its music have played a major role in breaking down cultural boundaries and bringing the people of the world together for purposes of performing on the instrument. From the findings of this study, I attribute most of the changes to technologisation, for most of the changes that have taken place on mbira dzavadzimu were a result of the highly technologised way of life Zimbabweans now lead.

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: The abundance of PHP-based Remote Access Trojans (or web shells) found in the wild has led malware researchers to develop systems capable of tracking and analysing these shells. In the past, such shells were ably classified using signature matching, a process that is currently unable to cope with the sheer volume and variety of web-based malware in circulation. Although a large percentage of newly-created webshell software incorporates portions of code derived from seminal shells such as c99 and r57, they are able to disguise this by making extensive use of obfuscation techniques intended to frustrate any attempts to dissect or reverse engineer the code. This paper presents an approach to shell classification and analysis (based on similarity to a body of known malware) in an attempt to create a comprehensive taxonomy of PHP-based web shells. Several different measures of similarity were used in conjunction with clustering algorithms and visualisation techniques in order to achieve this. Furthermore, an auxiliary component capable of syntactically deobfuscating PHP code is described. This was employed to reverse idiomatic obfuscation constructs used by software authors. It was found that this deobfuscation dramatically increased the observed levels of similarity by exposing additional code for analysis.
