- Description: The term “trade” is defined in very wide terms in the Income Tax Act and includes a “business” and a “venture”. For a taxpayer to claim certain deductions in arriving at taxable income, the taxpayer must be carrying on a trade. The expression “carrying on a trade” is not defined in the Income Tax Act. Whether or not a taxpayer is carrying on a trade is a matter of fact. Case law has established certain principles and tests to be applied in determining whether a taxpayer is carrying on a trade. The goal of the thesis was to determine to what extent an activity can be considered as carrying on a trade. This research focused on the letting of property, money-lending, or farming operations in relation to carrying on a trade or business or engaging in a venture. The thesis also discussed at what stage a taxpayer ceases to carry on a trade and what the tax consequences are of ceasing to trade. An interpretative research approach was used in the research as it sought to understand and describe. No interviews conducted for this research and the data used for the research are publicly available. It was established that “carrying on a trade”, including a business, requires an active step taken by the taxpayer to trade. It involves regularity of buying and selling or rendering of services. The intention to trade is important but it is a subjective matter and cannot be persuasive in determining whether a taxpayer is carrying on a trade; objective factors are also considered. If the stated intention to trade matches the actions of the taxpayer, the taxpayer will be considered to be carrying on a trade. In determining whether a taxpayer is carrying on a trade each case must be considered with its own merits.

- Description: Coastal ecosystems are more than microhabitats for marine species. Acting as atmospheric carbon filters, species in coastal environments are directly and/or indirectly associated with transferring organic carbon to species at higher trophic levels. However, the progressing change in global climatic conditions has created the need to assess the consequences of the shifting conditions on both direct and indirect interactions of physical and biological parameters at species and/or community levels. From these perturbations, the effects of biotic homogenization on ecosystem functioning and resilience can also be realised. Herein, I discuss the effects of temperature, nutrients, biotic interactions and habitat characteristics on community dynamics within intertidal rock pool systems on the south coast of South Africa using complementary qualitative and quantitative analytical methods. Seasonality had a significant impact on rock pool species with changes in composition and higher richness in winter than summer. The first two axes of the Canonical Correspondence Analysis (CCA) of the plant and animal communities each explained ~20% of the relationship between physico-chemical parameters and biological variables. The CCA highlighted that seasonal shifts in chlorophyll-a, conductivity, salinity, water depth, surface area and substratum type indirectly influenced species composition. For example, pools with heterogenous substratum comprising a mixture of sand and rock exhibited higher species diversity than homogenously bedded pools. Furthermore, a Bayesian analysis of community structure based on stable isotope ratios was used to assess how trophic pathways of carbon and nitrogen elements reflected community composition and richness. Isotopic biplots showed an increase in food web size, food chain length and the trophic positions of fish and some gastropods in winter compared to summer. There was greater dietary overlap among species in larger pools. In addition, while isotopic nearest neighbour distance and species evenness also showed a positive increase with pool size in summer, the same metrics were almost constant across all pool sizes in winter. These changes in food web packing and species evenness suggest seasonal preferences or migration of species in summer from small pools to larger pools with stable physico-chemical parameters. Furthermore, the presence of fish was seen to promote trophic diversity within some pools. The results from laboratory microcosm grazing experiments demonstrated significant direct and indirect effects of temperature and nutrients within plankton communities. Copepod grazing had an indirect positive influence on phytoplankton biomass and size structure while the interactive effects of temperature and nutrients had contrasting effects on both phytoplankton communities and copepod biomass. Shifts in water chemistry and nutrient treatments were also observed in the presence of copepods. Phosphate addition had a recognisable impact on plankton communities. The presented synthesis of the literature mainly highlighted that positive effects at one trophic level do not always positively cascade into the next trophic level which is evidence of complex interactive biotic, habitat and water chemistry effects within these intertidal ecosystems. Thus, to further understand cascading effects or community structure functioning in general, there may be a need to incorporate and understand species functional traits and how they contribute to trophic diversity, community restructuring and functioning in coastal habitats.

- Description: In the South African context, it is accepted that small businesses will be the vehicle for job creation and changing the current business ownership patterns. This is to be achieved by creating access to finance, exploring the role of venture capital and simplifying the tax obligations and the compliance burden. The literature indicates that the current South African tax incentives for small businesses are perceived as unfair and fundamentally ineffective. The objective of this thesis was to compare the tax incentives available to small businesses and investors in small businesses in South Africa to those available in Australia, New Zealand, Singapore and Ireland, in order to identify possible measures that could be introduced in South Africa. In addressing the objective, the research set out to provide, in terms of South African tax legislation, a definition of a small business for tax purposes and document the tax incentives available for start-up and existing small businesses, as well as the tax incentives available for investors in small businesses, either through a venture capital company or a direct investment in small business. It was found that South Africa has a complex and onerous multi-layered approach to classifying a taxpayer as either a “micro business” or a “small business corporation” for the purpose of applying tax incentives. The international jurisdictions included in this research follow a single requirement approach, based on either one or a combination of turnover, balance sheet total or staff headcount. The international jurisdictions provide a wide range of tax incentives to small businesses and investors in small businesses, aimed at reducing taxable income to enable the small businesses to grow and access equity finance. By identifying differences and similarities, a number of possible tax relief measures were recommended that could be introduced in South Africa.

- Description: Every day, computer networks throughout the world face a constant onslaught of attacks. To combat these, network administrators are forced to employ a multitude of mitigating measures. Devices such as firewalls and Intrusion Detection Systems are prevalent today and employ extensive Deep Packet Inspection to scrutinise each piece of network traffic. Systems such as these usually require specialised hardware to meet the demand imposed by high throughput networks. Hardware like this is extremely expensive and singular in its function. It is with this in mind that the string search algorithms are introduced. These algorithms have been proven to perform well when searching through large volumes of text and may be able to perform equally well in the context of Deep Packet Inspection. String search algorithms are designed to match a single pattern to a substring of a given piece of text. This is not unlike the heuristics employed by traditional Deep Packet Inspection systems. This research compares the performance of a large number of string search algorithms during packet processing. Deep Packet Inspection places stringent restrictions on the reliability and speed of the algorithms due to increased performance pressures. A test system had to be designed in order to properly test the string search algorithms in the context of Deep Packet Inspection. The system allowed for precise and repeatable tests of each algorithm and then for their comparison. Of the algorithms tested, the Horspool and Quick Search algorithms posted the best results for both speed and reliability. The Not So Naive and Rabin-Karp algorithms were slowest overall.

- Description: Mining is one of the most contentious water users. The mining sector has assumed that promises of economic growth and job creation will enable environmental concerns to be bypassed with as little interference as possible. More recently, the reality of legacy issues related to the inappropriate sign-off of mining sites has become increasingly clear, with acid mine drainage (AMD) being a prime example. There are also increasing concerns regarding uncontrolled prospecting. Climate change is one of the major issues faced in the 21st century, with predictions of heightened water stress for the Southern African region. This, coupled with increased population growth is putting a massive strain on the water resources currently available, making it vital to better protect and ensure the longevity of our water resources. The Carolina Crisis of 2012 highlighted the importance of protecting our water resources, and how easily they can be contaminated to a point where water is not usable. The Carolina crisis provided researchers with a suitable study site to better understand the role mining operations have in a catchment that has experienced a major pollution incident, and what changes have occurred since. In order to understand coal mining practice in relation to regulatory provisions, this project critically explored the processes involved within the mining sector, from ‘cradle-to-grave’, which is known as the coal mining life cycle. In addition, the composite suite of requirements of all the legislative provisions involved in the industry were investigated and the relationship between coal mining practice and environmental protection was explored. These elements were researched in the Upper Komati River Catchment specifically for catchment X11B, using Cultural Historical Activity Theory (CHAT), which gives a holistic understanding of mining as a human activity system. CHAT also sheds light on the issues, gaps and overlaps currently being experienced in the coal mining sector. The Thesis refers to case studies of where mining issues have caused environmental degradation. A complete mining lifecycle in terms of regulatory provisions was compiled, and major issues were uncovered with current legislation in the mining sector that can contribute to the degradation of water resources in South Africa. An integrated water resource quality management plan is needed in order to streamline conservation mandates, identify and reduce duplication of effort and specify roles and responsibilities of authorities involved with decision making process. A Decision Support System (DSS) has been proposed, which would involve adaptive, participatory and inclusive management.

- Description: This research investigates the design and development of a Wireless MIDI Connection Management solution in order to create a deterministic MIDI transmission system. A investigation of the MIDI protocol show it to have certain limitation that can be overcome through the use of transmission solutions. These solutions can be used to improve on the versatility of MIDI while overcoming the MIDI's notorious cable length limitation. XMOS's deterministic XS1 microcontrollers are used to enable the design of a real-time system. The MIDINet system is investigated to identify both the strengths and weaknesses of such a connection management system, while other systems for network transmission of MIDI messages are reviewed. These investigations lead to a design concept for a new network MIDI transmission system that allows for the remote management of connections. The design and subsequent implementation of both the transmission system and the connection management system are then detailed. A testing methodology is then devised to allow for the newly created connection management system to be compared to the MIDINet system. The findings show the deterministic system to have lower latency than that of the MIDINet system, while utilising more compact and power efficient hardware.

- Description: The objective of this thesis was to critically analyse the deductibility of bad debts for income tax purposes. This was achieved by applying a doctrinal research methodology to the data, which consisted of local and international legislation and case law, as well as other relevant writings. In setting out to achieve this primary objective, this thesis addressed certain subsidiary goals. The requirements of section 11 (i) of the South African Income Tax Act that provides for the deduction of bad debts were examined with reference to local case law, together with case law from selected international jurisdictions. To clarify the requirement of section 11 (i) that a debt must have become bad, this thesis set out to ascribe a meaning to the term “bad debt” which is currently not defined in the South African Income Tax Act and to ascertain the principles applicable in determining when a debt will be regarded as having become bad. The research also addressed the timing in relation to the identification of a debt as bad, as well as other commercial considerations. This research concluded that there is a need for further guidance in this area and provided brief recommendations that could provide more certainty in relation to the deductibility of bad debts.

- Description: There is a dearth of research on how the design and curriculum of a Master of Education (MEd) qualification for university-based teacher educators of prospective secondary school teachers may or may not contribute to the problem of poor secondary school learning outcomes in Tanzania. This qualitative study analyses the establishment, conceptualisation, design and curriculum components of selected MEd programmes with the purpose of identifying and explaining the conditions enabling and/or constraining the development of quality teacher educators. The research used a case study design to investigate how and why particular knowledge is privileged in two MEd programmes at two Tanzanian universities with a view to probing the relevance of the knowledge to teacher educators professional roles and practices. The study used critical realism as an under-labourer to investigate power structures and the generative and causal mechanisms underlying the two MEd programmes. The study draws on aspects of Bernstein’s theory as analytical tools to explain what emerges from the data. The data was collected from interviews, document analysis and observation, and analysed using thematic analysis, abductive and retroductive modes of inference. The research revealed and explains how underlying structural and agential mechanisms have shaped the establishment, conceptualisation and curriculum design of the two MEd programmes. The findings revealed a strong relationship between constraints, including the lack of appropriate MEd design team and the inadequacy of resources and facilities, and the quality of MEd graduates. Such constrains are possible mechanisms associated with the agential actions of the top administrators affect the relevance and appropriateness of the MEd curriculum components, the effective lecturers transmission and students acquisition of knowledge and skills. The research also explored how underlying mechanisms shaped the selection of course content and the privileging of certain types of teacher knowledge. These mechanisms include programme entry qualification, curriculum arrangement of core and elective courses, the lack of awareness of the knowledge and skills requisite for teacher educators’ specialisation, and the absence of recontextualisation principles to guide appropriate selection and recontextualisation of the relevant teacher educator’s courses. There is evidence that both MEd programmes have insufficient pedagogical knowledge and lack large components of academic content knowledge of teaching. An emphasis on individual disciplinary education courses with strong boundaries between modules and topics, aimed at developing specific education specialisations, results in teacher educator professional knowledge being less developed. Furthermore the accumulation and repetition of inappropriate knowledge has resulted in these programmes being weak regions for teacher educators’ professional fields of practice. This has implications for the quality of the secondary school teacher professional development courses on which these MEd graduates teach. It raises questions about the quality of the secondary school teachers being produced, and the extent to which this is contributing to the disappointing performance of Tanzanian schooling. The study generates insights into the mechanisms and conditions constraining the development of quality teacher educators. These conditions include the domination of higher education by customer demand, weak university regulatory systems, and the autonomy of university administration in terms of programme approval and other academic operations. Some administrators and lecturers showed an understanding of what would enable quality teacher educator development in the MEd programme. The findings of the research may help to strengthen and enhance quality assurance in the Master of Education programmes for teacher educators in Tanzania in ways that help develop quality secondary school teachers and improve school learning outcomes.

- Description: There is a dearth of research on how the design and curriculum of a Master of Education (MEd) qualification for university-based teacher educators of prospective secondary school teachers may or may not contribute to the problem of poor secondary school learning outcomes in Tanzania. This qualitative study analyses the establishment, conceptualisation, design and curriculum components of selected MEd programmes with the purpose of identifying and explaining the conditions enabling and/or constraining the development of quality teacher educators. The research used a case study design to investigate how and why particular knowledge is privileged in two MEd programmes at two Tanzanian universities with a view to probing the relevance of the knowledge to teacher educators professional roles and practices. The study used critical realism as an under-labourer to investigate power structures and the generative and causal mechanisms underlying the two MEd programmes. The study draws on aspects of Bernstein’s theory as analytical tools to explain what emerges from the data. The data was collected from interviews, document analysis and observation, and analysed using thematic analysis, abductive and retroductive modes of inference. The research revealed and explains how underlying structural and agential mechanisms have shaped the establishment, conceptualisation and curriculum design of the two MEd programmes. The findings revealed a strong relationship between constraints, including the lack of appropriate MEd design team and the inadequacy of resources and facilities, and the quality of MEd graduates. Such constrains are possible mechanisms associated with the agential actions of the top administrators affect the relevance and appropriateness of the MEd curriculum components, the effective lecturers transmission and students acquisition of knowledge and skills.

A critical discourse analysis of the Daily Nation and the Standard’s news coverage of the 2007/2008 Kenyan elections

- Description: This study investigates the Daily Nation and Standard’s news coverage of Kenya’s 2007/2008 general election and the unprecedented eruptions of violence which followed. This research responds to the question which came about as Kenyan print journalists and editors considered their role in possibly contributing to the violence, which took on an ethnic dimension. Vernacular radio has been fingered for having escalated longstanding ethnic tensions, but the role of the press has not been fully understood. In the aftermath of the violence, print journalists and editors met over a series of Round Table events in Nairobi to consider whether their conduct during the election could have encouraged violence. Although ten years have passed since this incidence, much of what happened within the Kenyan print media during and after the 2007/2008 general election remains unexplored and, largely, unexplained today. Although the pre- and post-election phases spanned months, my research is confined to purposive samples from a four-week period from 3 December 2007 to 4 January 2008. These four weeks were selected as they are roughly representative of the three phases of the national election which are considered significant to this study, namely the pre-election phase, the election, and the post-election violence. The research is concerned with analysing and understanding the coverage in the two dailies, the Daily Nation and Standard, and comparing the discursive work of the two, particularly in relation to identity and ethnicity. This study draws on cultural studies, critical discourse analysis and normative theories of the media to inform the research project. The critical discourse analysis explores the discourses articulated during and after the election, with a particular focus on issues of identity, ethnicity and incitement. Through this process the study found that both publications avoided references to ethnicity, despite this being an important factor in Kenyan politics and voter behaviour. In analysing these issues the study found that while the publications might claim to attempt to avoid fuelling tensions by not reporting on ethnicity, the disavowal comprised a silence which positioned the press in a collaborative role, in which it colluded with a powerful Kenyan state. Although a significant amount of time has gone by since the 2007/2008 elections, this study still considers the event significant in understanding the conduct of journalists during times of violence, and specifically for the future of journalism in Kenya.

- Description: Taking a feminist health psychology approach, we conducted a systematic review of published research on abortion featured in PsycINFO over a 7-year period. We analysed the 39 articles included in the review in terms of countries in which the research was conducted, types of research, issues covered, the way the research was framed and main findings. Despite 97per cent of abortions performed in Africa being classifiable as unsafe, there has been no engagement in knowledge production about abortion in Africa from psychologists, outside of South Africa. Given this, we outline the implications of the current knowledge base for feminism, psychology and feminist health psychology in Africa.

- Description: This thesis evaluated the language policy implementation strategies used in selected universities of South Africa. The Constitution of the Republic of South African (1996) recognises eleven official languages, namely: English, Afrikaans, isiNdebele, isiXhosa, isiZulu, Sesotho, Setswana, SiSwati, Sepedi, Tshivenda and Xitsonga. These official languages should enjoy the parity of esteem in all domains. The language practices are very important in the education of students at all levels of education but this study focuses on the language policy implementation in universities. Most universities of South Africa have their language policies but the dilemma is on the implementation of those language policies. The overarching aim of this study is to evaluate how university use language policy for access and success of the students and to assess the language policy implementation strategies, monitoring and evaluation. The language is central to the success of the students and this study further investigated to what extent are the universities use the linguistic repertoires of the students in their education. This study is rooted in orientations of language planning: Language as problem, language as right and language as resource (Ruiz, 1984). This thesis employed a mixed methods approach (qualitative and quantitative method) with convergent parallel design. The data was collected from eleven universities of South Africa and the participants in each university were the "Key informants" (experts and insiders) which comprised of member of Executive Management, a member of the Institutional Language Committee and a language lecturer; and a cohort of forty third year students. The Key informants participated in the qualitative data collection through the structured interviews. The forty third year students participated in the quantitative data collected through survey questionnaires. The language policy documents of the universities were also sampled to get a better understanding of the real language practices and the language policy. The thematic analysis was used to analyse transcripts that were developed from the interviews, data from the students was analysed through descriptive and inferential analyses with Statistical Package for the Social Sciences (SPSS) as a statistical test and document analysis was used to analyse the language policies; The findings show that universities have commitment to access of the students to institutions of Higher Education. The success of the students is being thwarted by the monolingual approach where most of the universities use English only as the medium of instruction. The monolingual approach negatively affects the academic success and excellent academic performance of the majority of students. The findings show that there is high demand from the students that the course materials should be provided in African languages. All selected universities have their language policy which is something positive but most of them are outdated because they need to be reviewed at least after five years. The findings demonstrate that most universities lack the language policy implementation plans. The nonexistence of the language policy implementation plan adversely affects the implementation of the language policy. The study recommends that universities should provide the learning resources in African languages to meet the demands of the students. To maximise the success, students should be examined in any official languages of the university. The language policy implementation plans should be developed urgently so as to improve language policy implementation in universities. , Le thesisi iphonononge iindlela zokusetyenziswa komgaqo-nkqubo wolwimi kwiiyunivesithi ezichongiweyo zaseMzantsi Afrika. Umgaqo-siseko waseMzantsi Afrika (1996) athathela ingqalelo iilwimi ezisemthethweni ezilishumi elinanye, isiNgesi, isiBhulu, isiNdebele, isiXhosa, isiZulu, Sesotho, Setswana, Sepedi, SiSwati, Tshivenda neXitsonga. Ezi lwimi zisemthethweni zifanele ukuba zisetyenziswe ngokulinganayo kuzo zonke iinkalo. Ukusetyenziswa kweelwimi kubalulekile kakhulu kwimfundo yabantwana kuwo onke amanqanaba emfundo kodwa olu phando lugxile ekusetyenzisweni komgaqo-nkqubo wolwimi kwiiyunivesithi. Uninzi lweeyunivesithi zinayo imigaqo-nkqubo yolwimi kodwa ingxaki isekusetyenzisweni kwaloo migaqo-nkqubo yolwimi. Ezona njongo zolu phando kukuphonononga ukuba iiyunivesithi ziyisebenzisa njani na imigaqo-nkqubo yolwimi ukuze abafundi bafikelele kwaye baphumelele ezifundweni kwakhona nokugocagoca izicwangciso zokusetyenziswa komgaqo-nkqubo wolwimi nokuhlola ukusebenza kwezo zicwangciso. Ulwimi ngundoqo kwimpumelelo yabafundi kwaye umyinge wokusetyenziswa kweelwimi zabafundi ekufundeni kwabo kuthe kwaphandwa. Esi sifundo sisekelwe kwiindlela zocwangciso-lwimi: Ulwimi njengengxaki, ulwimi njengelungelo nolwimi njengesixhobo (Ruiz, 1984). Le thesisi esebenzise indlela yophando entlantlu-mbini (eyobunjani neyobungakanani) kunye noyilo lwendibaniso kokunxuseneyo. Idatha yathi yaqokelelwa kwiiyunivesithi ezilishumi elinanye eMzantsi Afrika kwaye abathabathi nxaxheba babandakanya ilungu lesigqeba solawulo, ilungu lekomiti yeelwimi eyunivesithi nomhlohli wolwimi; kunye nabafundi abakunyaka wesithathu kwizifundo zabo kwiyunivesithi nganye. Idatha yaqokelelwa kubadlulisi-lwazi abaphambili beeyunivesithi ngodliwano-ndlebe oluqingqiweyo. Abafundi abalishumi elinesine bathi bathabathi inxaxheba kuqokelelo lwedatha ngokuthi bagcwalise uludwe lwemibuzo eyayicwangcisiwe. Umaxwebhu omgaqo-nkqubo wolwimi athi achongwa ukuze kubekho ukuqondakala phakathi kokusetyenziswa kolwimi kunye nokumgaqo-nkqubo wolwimi. Uhlalutyo ngokomxholo lwathi lwasetyenziswa ukuhlalutya ulwazi olwabhalwayo luvela kudliwano-ndlebe olwashicilelwayo, idatha eyayisuka kubafundi yathi yahlalutywa ngokusebenzisa uhlalutyo ngokwenkcazelo nangokuthelekelela kunye neStatistical Pakage for Social Sciences (SPSS) njengesixhobo senkcukacha-manani kwaye uhlalutyo loxwebhu lwathi lwasetyenziswa ukuhlalutya imigaqo-nkqubo yolwimi. Iziphumo zibonakalisa ukuba iiyunivesithi zizibophelele ekufikelelekeni kwabafundi kumaziko emfundo ephakamileyo. Impumelelo yabafundi ithi ithityazwe kukusetyenziswa kolwimi olunye apho uninzi lweeyunivesithi zisebenzisa isiNgesi kuphela njengolwimi lokufunda nokufundisa. Ukusetyenziswa kolwimi olunye kuthi kuchaphazela gwenxa impumelelo yabafundi nokuqhuba ngcono ezifundweni. Iziphumo zibonakalisa ukuba kukho imfuno emmandla kubafundi yokuba izixhobo zokufunda nokufundisa zifumaneke nangeelwimi zesiNtu. Inyathelo elihle lelokuba zonke iiyunivesithi ezichongiweyo zinayo imigaqo-nkqubo yolwimi kodwa imigaqo-nkqubo yolwimi emininzi midala kuba ifanelwe ukuba iphononongwe emva kweminyaka emihlanu ubuncinane. Iziphumo zibonakalisa ukuba iiyunivesithi azinazo izicwangciso zokusetyenziswa kwemigaqo-nkqubo yolwimi. Ukungabikho kwesicwangciso sokusetyenziswa komgaqo-nkqubo wolwimi kuchaphazela gwenxa ukusetyenziswa kwawo. Olu phando lundulula ukuba iiyunivesithi zifanele ukuba zibonelele ngezixhobo zokufunda nokufundisa ezingeelwimi zesiNtu ukukhawulelana neemfuno zabafundi. Ukwandisa impumelelo, abafundi kufanele ukuba bavavanywe ngalo naluphi na ulwimi olusemthethweni lweyunivesithi. Izicwangciso zokusetyenziswa komgaqo-nkqubo wolwimi zifanele ukuba ziveliswe njengenyewe engxamisekileyo ukuze kuphuculwe ukusetyenziswa kwemigaqo- nkqubo yolwimi kwiiyunivesithi.

- Description: Language is an essential tool in effecting transformation in a community, society as well as in a culturally diverse institution like the Parliament of South Africa. This study is undertaken to establish the progress made in the use of official languages in the Parliament of South Africa. This study critically looks at the use of eleven South African official languages by the Parliament of South Africa in its daily debates in ensuring transformation to a multilingual parliament. The focus of the study is on the publication of Hansard in all official languages, with specific reference to previously marginalised languages as declared by the Constitution. The study was done in the Language Service Section of the Parliament of South Africa. Firstly, the study looked at the History of Parliament and Hansard publications in relation to the sittings and debates of MP’s since the beginning of Parliament in South Africa. Secondly, a literature review was done on Language Policy implementation, monitoring and promotion of languages in South Africa. Review of legislative frameworks on language matters was undertaken in order to find out the compliance of parliament in using official languages in the publication of Hansard. The study evaluates the recognition of languages as well as the parliamentary in-House Language Policy (Operational Language Policy) in relation to the prescriptions of the Constitution. Findings of the study are indicated in chapter 5 of the thesis. The presentation of data comprises of the work experience of the languages practitioners in parliament, availability and critique of the Language Policy Operational Policy in Parliament, as well as findings in the published Hansard Volumes since the first parliament. The study further tries to look at challenges that hinder the use, and promotion of all languages in parliament, including the use of these languages in the publication of Hansard. The study focuses on minority languages and previously marginalised languages. Recommendations are provided as a means of helping to improve the situation regarding the implementation of the language policy that will assist parliament to transform in order to become truly multilingual. This will allow parliament to be in a position to develop previously marginalised languages.

- Description: Language is an essential tool in effecting transformation in a community, society as well as in a culturally diverse institution like the Parliament of South Africa. This study is undertaken to establish the progress made in the use of official languages in the Parliament of South Africa. This study critically looks at the use of eleven South African official languages by the Parliament of South Africa in its daily debates in ensuring transformation to a multilingual parliament. The focus of the study is on the publication of Hansard in all official languages, with specific reference to previously marginalised languages as declared by the Constitution. The study was done in the Language Service Section of the Parliament of South Africa.

- Description: Mental illness rates are climbing, locally and globally. The World Health Organization (2001) has claimed that one in four people will be affected by a psychiatric disorder during their lifetime. With this in mind, there is an array of psychometric assessment measures that are used as tools to assist in the mental health care field. Two such measures are the Beck Anxiety Inventory (BAI) and the Beck Depression Inventory-II (BDI-II). These measures are used globally to assist with the diagnosis and treatment of depression and anxiety. However, in South Africa, a paucity of normative indicators exists. This research set out to determine if there are significant differences in performance on the BAI and BDI-II when comparing a sample from the Eastern Cape, South Africa, to the international norms. It was found that performances on the BAI between the local sample and the international sample did not differ significantly. The local sample, on average, performed 4.76 points lower on the BDI-II than those assessed in the international norms. A series of theoretical models are explored in elucidating the findings in this study. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2018

- Description: In Namibian schools, learner voice and leadership are being promoted through the policy document entitled the Education Act 16 of2001 which provides an opportunity to establish Learner Representative Councils (LRCs) in secondary schools. However, recent studies have found that this body of learner leaders do not function all that effectively and sometimes exist for the sake of adhering to the policy. This prompted me to conduct an activity theoretical interventionist case- study within the critical paradigm, to develop LRC voice and leadership in a newly established Namibian school. Framed by Cultural Historical Activity Theory, the study was divided into two phases to answer the over-arching question: How can LRC voice and leadership be developed in a school? Phase one was largely interpretive, the contextual profiling phase, where document analysis, individual interviews, questionnaires and observations were used to generate data to answer the following research sub-questions: How is learner leadership understood in the school? What leadership development opportunities for the LRC currently exist in the school? What underlying factors constrain the development of LRC voice and leadership in the newly established school? Phase two of the study was the expansive learning phase, which consisted of three intervention workshops. The Change Laboratory method and a focus group interview were used to generate data in response to the last research sub-question: In what ways can LRC participation in a Change Laboratory process contribute to their leadership development? Data generated were inductively and deductively analysed, using the activity theoretical principles of contradictions and double stimulation. Data revealed that learner leadership was largely understood as managerial roles carried out by the LRC in the school. Unlike many schools in Namibia, this case-study school offered numerous leadership development opportunities for the LRC. The community networking events such as: School Exchange Programmes, Town Council breakfast and Junior Regional Council, were opportunities offered to the LRC to solicit information, exchange ideas and discuss matters of common interest with the LRCs of the fully established schools. However, there were a number of challenges that constrained LRC voice and leadership development, the major one being the fact that this was a newly established school. Of significance was that LRC participation in the Change Laboratory process contributed positively to the development of voice and leadership in learners. During this Change Laboratory process, the LRC developed a new artefact - the vision and mission statement of the school - this signified that the learners expansively transformed the object of their activity. Recommendations emerging out of the study included that the School Management Team see the ‘newly established’ status of the school as an opportunity for development, rather than a limitation, and therefore invite the LRC to participate in the different leadership practices as the school becomes established. A significant recommendation for school leadership research is to use the third generation of CHAT to expand the unit of analysis, in order to understand the leadership relations and power dynamics between multiple activity systems in schools as complex organisations.

- Description: Numerous software agents exist and are responsible for increasing volumes of malicious traffic that is observed on the Internet today. From a technical perspective the existing techniques for monitoring malicious agents and traffic were not developed to allow for the interrogation of the source of malicious traffic. This interrogation or reconnaissance would be considered active analysis as opposed to existing, mostly passive analysis. Unlike passive analysis, the active techniques are time-sensitive and their results become increasingly inaccurate as time delta between observation and interrogation increases. In addition to this, some studies had shown that the geographic separation of hosts on the Internet have resulted in pockets of different malicious agents and traffic targeting victims. As such it would be important to perform any kind of data collection over various source and in distributed IP address space. The data gathering and exposure capabilities of sensors such as honeypots and network telescopes were extended through the development of near-realtime Distributed Sensor Network modules that allowed for the near-realtime analysis of malicious traffic from distributed, heterogeneous monitoring sensors. In order to utilise the data exposed by the near-realtime Distributed Sensor Network modules an Automated Reconnaissance Framework was created, this framework was tasked with active and passive information collection and analysis of data in near-realtime and was designed from an adapted Multi Sensor Data Fusion model. The hypothesis was made that if sufficiently different characteristics of a host could be identified; combined they could act as a unique fingerprint for that host, potentially allowing for the re-identification of that host, even if its IP address had changed. To this end the concept of Latency Based Multilateration was introduced, acting as an additional metric for remote host fingerprinting. The vast amount of information gathered by the AR-Framework required the development of visualisation tools which could illustrate this data in near-realtime and also provided various degrees of interaction to accommodate human interpretation of such data. Ultimately the data collected through the application of the near-realtime Distributed Sensor Network and AR-Framework provided a unique perspective of a malicious host demographic. Allowing for new correlations to be drawn between attributes such as common open ports and operating systems, location, and inferred intent of these malicious hosts. The result of which expands our current understanding of malicious hosts on the Internet and enables further research in the area.

- Description: Non-Governmental Organisations (NGOs) have occupied a prominent role in the socio-economic development of rural areas of Zimbabwe since the time of the country’s independence in 1980, including a focus on improving the conditions and status of women in communal areas. These NGOs adopt a participatory methodology in their development programmes and projects, as they try to ensure that the active participation of women in rural development facilitates women’s access to resources and the realisation of their rights. These initiatives are important given the pronounced system of patriarchy which exists in communal areas. In the context of local patriarchies, NGOs also often claim that they empower women. This thesis focuses on the work of one particular NGO programme, namely the Amalima programme, with a particular focus on three wards in the communal areas in Gwanda, Zimbabwe. From a gendered perspective concerned with questions of women’s empowerment, the main objective of the thesis is to provide a critical analysis of the Amalima programme with particular reference to married women in Gwanda. Based on original fieldwork (including interviews with men, women and NGO practitioners), the thesis concludes that the outcomes of the Amalima programme in empowering married women in Gwanda are uneven and that, overall, the local system of patriarchy (including at household level) remains largely intact.

Complex 3 was subsequently reacted with gold nanoparticles (AuNPs), chitosan (CT) and a gold–chitosan (AuCT) hybrid to form 3-AuNPs, 3-CT and 3-AuCT, respectively. The conjugates afforded a decrease in fluorescence quantum yield with a corresponding increase in the triplet and singlet quantum yields compared to complex 3. The in vitro dark cytotoxicity and photodynamic therapy activity (PDT) of complex 3 and 3-AuCT composites were investigated against epithelial breast cancer cells (MCF-7) with both the samples showing minimum dark cytotoxicity. They both accounted for a cell viability of ≥90% at a concentration of ≤59.2 μg mL−1. 3-AuCT showed better PDT activity (compared to 3 alone) with less than 50% viable cells at a concentration of ≥29.6 μg mL−1 making it potentially applicable for PDT. On the other hand, AuCT displayed some activity against cancer cells, probably due to photothermal activity since gold is a light absorber, however it had more than 50% viable cells at a concentration of ≤59.2 μg mL−1.

- Description: Heterocyclic structures have found extensive utility in the field of medicinal chemistry, as prominent regions of pharmacophores resulting in numerous drug treatments for many diseases. Accordingly, in this project we explored the respective antimalarial and anticancer activity exhibited by compounds featuring nitrogen containing indole and tetrazole heterocycles respectively. This thesis therefore comprises of two distinct parts. Part 1. Following the development of resistance towards traditional antimalarial therapy such as chloroquine and emerging resistance towards artemisinin combination therapies, the WHO reported the urgent need for new, effective drugs and identification of new drug targets to combat the Plasmodium falciparum parasite. In 2015 the parasite was the cause of 429 000 deaths, the majority occurring in the sub-Saharan region of Africa. This highlights the failing effectiveness of vector control strategies, reiterating the need to develop alternative control and treatment strategies. In response to this need we wanted to expand and further describe the SAR of the indole based series, indolyl-3-ethanone-α- thioethers, previously synthesized in our laboratory. These compounds were found to exhibit antimalarial activity with compounds 2.26 and 2.27 exhibiting activity against P. falciparum 3D7 in the nanomolar range. Based on these compounds we synthesized compounds 3.21 and 3.24 – 3.32 following a three step reaction pathway. Our results in this study, indicate that compound 3.28, a pnitrothiophenol analogue of 2.27 was the most active of the compounds we synthesized and furthermore was superior in activity against Plasmodium compared to 2.27. This result indicated that the presence of p-NO2 is important in enhancing anti-plasmodial activity. Comparing compounds 3.25 and 3.26 with an oxygen on the ether bridge to compounds 3.29 and 3.30 with a sulfur, we observed an increase in hydrophilicity coupled to a decrease in anti-plasmodial activity in the compounds, thus, highlighting the importance of sulfur for enhanced activity. Furthermore, we investigated bioisosteric replacement of the 5-chloro substituent present in hit compounds 2.27 and 3.28, with an electron withdrawing nitrile (3.27) and electron donating methyl (3.29) and methoxy (3.31) substituents. These substituents decreased anti-plasmodial activity, confirming that a chlorine substituent is optimal for biological activity. This study furthered our understanding of the SAR of indolyl-3-ethanone-α- thioethers for the development of potent anti-plasmodial lead compounds. Part 2. Triple negative breast cancer (TNBC), which disproportionately affects women of sub-Saharan Africa, is unresponsive to hormone-based therapies. This emergence presents a population of patients devoid of effective drug treatment, signaling the urgent need to develop new effective therapies with novel drug targets. Therefore, we identified our target in TNBC cells as the protein-protein interaction between the co-chaperones HOP and HSP90. We reasoned that a disruption of this interaction would ultimately result in cancer cell death via the degradation of essential oncogenic client proteins. Following a fragment screening campaign, which identified several acid and tetrazole containing hits (4.56 – 4.58) which bound to HOP, with low anticancer activity, we sought to develop synthetic methodology to elaborate our fragment hits synthesizing tetrazole containing fragments to target TNBC cell lines. We therefore proceeded to synthesize a range of multi substituted fragments (4.59 – 4.63), utilizing a nitrile (4.66) to access tetrazoles via 1,3-cycloaddition and an acid by nitrile hydrolysis. We successfully synthesized the tetrazole and acid fragments which are currently undergoing characterization for activity against TNBC. , Thesis (MSc) -- Faculty of Pharmacy, Pharmacy, 2018

Our results in this study, indicate that compound 3.28, a pnitrothiophenol analogue of 2.27 was the most active of the compounds we synthesized and furthermore was superior in activity against Plasmodium compared to 2.27. This result indicated that the presence of p-NO2 is important in enhancing anti-plasmodial activity. Comparing compounds 3.25 and 3.26 with an oxygen on the ether bridge to compounds 3.29 and 3.30 with a sulfur, we observed an increase in hydrophilicity coupled to a decrease in anti-plasmodial activity in the compounds, thus, highlighting the importance of sulfur for enhanced activity. Furthermore, we investigated bioisosteric replacement of the 5-chloro substituent present in hit compounds 2.27 and 3.28, with an electron withdrawing nitrile (3.27) and electron donating methyl (3.29) and methoxy (3.31) substituents. These substituents decreased anti-plasmodial activity, confirming that a chlorine substituent is optimal for biological activity. This study furthered our understanding of the SAR of indolyl-3-ethanone-α- thioethers for the development of potent anti-plasmodial lead compounds. Part 2. Triple negative breast cancer (TNBC), which disproportionately affects women of sub-Saharan Africa, is unresponsive to hormone-based therapies. This emergence presents a population of patients devoid of effective drug treatment, signaling the urgent need to develop new effective therapies with novel drug targets. Therefore, we identified our target in TNBC cells as the protein-protein interaction between the co-chaperones HOP and HSP90. We reasoned that a disruption of this interaction would ultimately result in cancer cell death via the degradation of essential oncogenic client proteins. Following a fragment screening campaign, which identified several acid and tetrazole containing hits (4.56 – 4.58) which bound to HOP, with low anticancer activity, we sought to develop synthetic methodology to elaborate our fragment hits synthesizing tetrazole containing fragments to target TNBC cell lines. We therefore proceeded to synthesize a range of multi substituted fragments (4.59 – 4.63), utilizing a nitrile (4.66) to access tetrazoles via 1,3-cycloaddition and an acid by nitrile hydrolysis. We successfully synthesized the tetrazole and acid fragments which are currently undergoing characterization for activity against TNBC. , Thesis (MSc) -- Faculty of Pharmacy, Pharmacy, 2018
