- Description: This is a collection of village narrative poems mainly set in rural Limpopo that searches into the complexity of the past and how historical events impact on the present. Although the poems are imagined along the Marxist dialectic, they’re fresh imaginative creations featuring a strong element of surprise, spiritual mysticism, experimenting with form, delving into unknown poetic avenues, creating new music, exploring new sounds and taking risks. The long and intense poem, Ancestral wealth, which is a tribute to the poet’s father, reflects on death and its impact through the effective application of various stylistic elements and poetic devices, thus immortalising the life of a rural South African. Overall the poems, including retrospective and experimental ones, condemn the free market economic system and all that it seems to necessitate: the degradation of ecology, indifference to human suffering and the alienation of vulnerable social groups.

- Description: Even if all the technical security solutions appropriate for an organisation’s network are implemented, for example, firewalls, antivirus programs and encryption, if the human factor is neglected then these technical security solutions will serve no purpose. The greatest challenge to network security is probably not the technological solutions that organisations invest in, but the human factor (non-technical solutions), which most organisations neglect. The human factor is often ignored even though humans are the most important resources of organisations and perform all the physical tasks, configure and manage equipment, enter data, manage people and operate the systems and networks. The same people that manage and operate networks and systems have vulnerabilities. They are not perfect and there will always be an element of mistake-making or error. In other words, humans make mistakes that could result in security vulnerabilities, and the exploitation of these vulnerabilities could in turn result in network security breaches. Human vulnerabilities are driven by many factors including insufficient security education, training and awareness, a lack of security policies and procedures in the organisation, a limited attention span and negligence. Network security may thus be compromised by this human vulnerability. In the context of this dissertation, both physical and technological controls should be implemented to ensure the security of the SANReN network. However, if the human factors are not adequately addressed, the network would become vulnerable to risks posed by the human factor which could threaten the security of the network. Accordingly, the primary research objective of this study is to formulate guidelines that address the information security related human factors in the rolling out and continued management of the SANReN network. An analysis of existing policies and procedures governing the SANReN network was conducted and it was determined that there are currently no guidelines addressing the human factor in the SANReN beneficiary institutions. Therefore, the aim of this study is to provide the guidelines for addressing the human factor threats in the SANReN beneficiary institutions.

- Description: This mini-thesis is a supporting document to the exhibition titled via: a phenomenological site-specific series of intermedia interventions and installations at the 1820 Settlers National Monument in Grahamstown. This mini-thesis examines ways in which one negotiates the movement of the self and interactions with others within the non-place. Non-places are ‘habitually transient’ spaces for passage, communication and consumption, often viewed from highways, vehicles, hotels, petrol stations, airports and supermarkets. Characteristic of these generic and somewhat homogenous spaces is the paradox of material excess and concurrent psychological lack where a feeling of disorientation and disconnection is established due to the excesses of Supermodernity: excess of the individual, time and space. The non-place is a contested space as it does not hold enough significance to be regarded as a place and yet, despite its banality, is necessary – and in many ways a privilege – in everyday living. I explore the concept of non-places in relation to the intricate notions of space and place, and draw on empirical research as a means to interrogate how one perceives the phenomenological qualities of one’s surroundings. I discuss the implications of the multiplication of the non-place in relation to globalisation, time–space compression, site-specific art and absentmindedness, as theoretical themes which underpin the practical component of my research. In addition, I situate my artistic practice in relation to other contemporary artists dealing with the non-place as a theme, and critically engage with the multi-disciplinary and sensory installations and video pieces of Belgian artist Hans Op de Beeck.

- Description: While South Africa stands apart from other countries as being more progressive in terms of gay and lesbian rights, attitudes towards this population continue to be intolerant. Attitudes shape people’s behaviour and in a university setting young students are vulnerable to discrimination. This is often a time when young people are still shaping their identities. An electronic survey comprising the Attitudes towards Lesbians and Gay Men Scale was administered to 401 students taking undergraduate psychology courses at the East London Campus of the University of Fort Hare, to assess their attitudes towards gays and lesbians. The survey measured their attitudes in terms of the biographical variables of gender, age, race, and religiosity, commitment to religious practice, urban or rural upbringing and nationality. The results of the research found that gender, race, religiosity, religious attendance and rural or urban upbringing do influence students’ attitudes significantly. However, age did not have an effect on attitudes towards gays and lesbians in the present study. The significance of the differences in attitudes in terms of nationality was not able to be tested due to the small sample size of foreign students. The findings of this study show that there are fairly consistent predictors of students’ attitudes concerning gays and lesbians. This information can help us to clarify areas to target for improvement in the campus climate for gay and lesbian communities.

- Description: The HIV and AIDS pandemic have become not only a health concern but educational and social concern as well. According to Beyers and Hay (2011, p. 99) many school-going children are not only affected by HIV but a large number of adolescents are also either HIV positive or have AIDS. Other researchers argue that education should act as a vaccine against new HIV infections (Kendall and O’Gara, 2007, p. 6). This argument comes with the expectation that all teachers are willing and ready to work with learners made vulnerable by HIV and AIDS; without considering the lived realities of the teachers in relation to HIV and AIDS. While many teachers make a difference in the lives of affected and infected learners through the way in which they deal with the learners concerned, some may not take up the challenge to assist the learners, while others might unknowingly and unintentionally do harm. This study, therefore, aimed at exploring high school teachers’ experiences of working with learners made vulnerable by HIV and AIDS in order to generate guidelines to assist teachers to effectively deal with vulnerable learners in their classrooms.

- Description: Kalaharituber pfeilii (Henn.) Trappe & Kagan-Zur commonly known as the “Kalahari truffle” is a desert truffle species identified from the Kalahari region of southern Africa. Two other species, Eremiomyces echinulatus (Trappe & Marasas) Trappe & Kagan-Zur and Mattirolomyces austroafricanus (Trappe & Marasas) Trappe & Kovacs are also known to occur in other parts of southern Africa. Truffles are hypogeous fruiting bodies of Ascomycetes, important to humans for their nutritional value and medicinal characteristics. These truffles are known as desert truffles as they prefer to occur under arid or semi-arid conditions characteristic of deserts. Truffle development depends on the presence of a mycorrhizal host, associated microorganisms as well as soil and climatic characteristics. It has been suggested that K. pfeilii has a suspected broad plant host range which includes herbaceous to woody trees and shrubs. However, these relationships have not been verified. Indigenous people of the Kalahari believe that truffles are found under grasses. In the Kalahari, truffle fruiting bodies are often found entangled in Stipagrostis ciliata (Desf.) De Winter var. capensis (Trin. & Rupr.) De Winter roots. S. ciliata, also known as the tall bushman-grass, is the most common grass found in the Kalahari. The objective of this study was to provide conclusive evidence that S. ciliata var. capensis is a host of the Kalahari truffle. Truffle fruiting bodies and grass roots from where the truffles were found were collected from Upington, South Africa. The fruiting bodies were identified by observing their morphological characteristics using the ‘Keys of Truffle genera’. All observed physical properties were similar to those of K. pfeilii and further identification was done using molecular techniques. DNA was extracted from the fruiting bodies, mycelial cultures, rhizosheaths and from the S. ciliata var. capensis grass roots, which were then amplified using the specific K. pfeilii specific primers TPF3 and TPR1 and sequenced. The obtained sequence results confirmed that the collected fruiting bodies were those of the K. pfeilii and the molecular techniques also confirmed that K. pfeilii DNA was present in the S. ciliata var. capensis rhizosheath and root cells. Microscopy showed an ectendomycorrhizal association between K. pfeilii and S. ciliata var. capensis. Mycorrhizal resynthesis experiments were conducted to establish this mycorrhizal association in-vitro. They were unsuccessful because of the structure of the grass and the availability of contaminants. And more...

- Description: The increase in teenage pregnancy among school going learners is reported in the media as a crisis. Politicians and other stakeholders have also raised their views and concerns about pregnancy. In particular, these views and concerns perceive teenage pregnancy among school going learners as a cancer that needs a remedy because it has negative consequences for the learners, in particular the girl child. However, for all the sense of public crisis concerning sexuality and schooling, the voices of young people themselves regarding their own sexual subjectivity are seldom heard. This study focused on how girls in a former model C all girls high school negotiate and make sense of the meaning of the messages that they receive from the formal curriculum. The concept of student sexual cultures was employed in this study. Student sexual cultures are the informal groups that exist in the school and the girls take part in it. It is in these groups that the girls learn about sexuality and also make sense of their own gendered identities. This study employed ethnographic techniques of classroom observation coupled with in-depth interviews, focus groups and solicited narratives in order to understand how the participants experience and "take up" the messages they receive in the formal sexuality education component of the Life Orientation (LO) curriculum. The data was collected over a period of three months and was analysed using a directed content analysis. Four dominant themes emerged from the study. Firstly, the data reveals the school is a space of competing and conflicting discourses of sexuality and the learners are involved in a constant negotiation of the meanings of the messages. Secondly, the data shows the contested and confirmations of learners subjectivity. It shows that learners are regarded as sexual beings both in the formal and informal school cultures but there are limitations around one's sexual subjectivities. Thirdly, the data reveals that the school is a site in which a variety of femininities are reproduced, contested and struggled over. Femininities are constructed in the complex context of the school thus the school emerges as a site in which multiple femininities intersect with class, race and sexuality. Lastly, this study argues for the incorporation of the discourse of erotics in the formal curriculum which allows young people's voices to be heard. This approach (discourse of erotics) can be seen as a process of becoming, which focuses on possibilities of improving sexuality education as opposed to an imposed sexual model that is applied to young people and assumed to be the solution to young people's sexuality.

- Description: In South Africa, the right to protest is under constant threat as a result of the state response. Increasing cases of forceful policing and sometimes unlawful procedural prohibitions of protest attest to this. This study aims to firstly describe this situation through securitisation theory, essentially arguing that South Africa has become a securitised state. It also aims to understand how this is sustained by the state and why the state needs to use a securitised response to maintain power. Interviews were conducted with members of different communities and organisations. Their responses helped to illustrate the frustration of the right to protest or brutal policing during a protest. This provided primary evidence to support the claims of the study. The research shows that claims to protest are being delegitimised under the guise of security as protestors are being constructed as threats to the state. This is further substantiated by looking at how the reorganisation and remililtarisation of the South African Police perpetuates the criminalisation of protestors which necessitates a forceful response from the state. Furthermore, it shows that there is a distinct relationship between the prohibition of protest and the recent increase in ‘violent’ protests which legitimate forceful policing thereby creating a state sustained cycle of violence. The larger implication of this treatment is that these protestors are treated as non- citizens who are definitively excluded from participating in governance. In understanding why this is taking place, it is clear that a securtitised response is an attempt to maintain power by dispelling any threats to power, a response which is seen to have a long history in the African National Congress (ANC) when examining the politics of the ANC during exile. Maintaining power in this way distracts from the larger agenda of the state, which this thesis argues, is to mask the unraveling of the ANC’s hegemony and inability to maintain national unity. In other words, the increasing dissatisfaction of some of the citizenry which has manifested through protest greatly undermines the legitimacy of the government to provide for its people.

- Description: In South Africa, the right to protest is under constant threat as a result of the state response. Increasing cases of forceful policing and sometimes unlawful procedural prohibitions of protest attest to this. This study aims to firstly describe this situation through securitisation theory, essentially arguing that South Africa has become a securitised state. It also aims to understand how this is sustained by the state and why the state needs to use a securitised response to maintain power. Interviews were conducted with members of different communities and organisations. Their responses helped to illustrate the frustration of the right to protest or brutal policing during a protest. This provided primary evidence to support the claims of the study. The research shows that claims to protest are being delegitimised under the guise of security as protestors are being constructed as threats to the state. This is further substantiated by looking at how the reorganisation and remililtarisation of the South African Police perpetuates the criminalisation of protestors which necessitates a forceful response from the state. Furthermore, it shows that there is a distinct relationship between the prohibition of protest and the recent increase in ‘violent’ protests which legitimate forceful policing thereby creating a state sustained cycle of violence. The larger implication of this treatment is that these protestors are treated as non- citizens who are definitively excluded from participating in governance. In understanding why this is taking place, it is clear that a securtitised response is an attempt to maintain power by dispelling any threats to power, a response which is seen to have a long history in the African National Congress (ANC) when examining the politics of the ANC during exile. Maintaining power in this way distracts from the larger agenda of the state, which this thesis argues, is to mask the unraveling of the ANC’s hegemony and inability to maintain national unity.

- Description: In the current global market, companies are forming partnerships with other organisations with the aim of sustaining their competitive advantage. Most organisations participate in transactions such as mergers, acquisitions and joint ventures in order to maintain their competitive advantage (Sorge, 2002). South Africa forms part of the global market and is not immune towards the stipulated growth strategies. It is believed that South Africa has one of the highest unemployment rate internationally (Human Capital Mangement, 2005). There are various reasons that have contributed towards this perception; factors such as structural changes in the labour market have been highlighted as one of the factors that have contributed to the high unemployment rate (HCM, 2005). It is further said that when mergers and acquisitions occurs, structural changes are bound to occur (Greeve, 2008). Despite the constant merger activities that are occurring in various industries, research has shown that most mergers add no value or reduce shareholders value for the acquiring firm (Kusewitt, 2007). The primary objective of this research is to investigate how organisational behaviour is influenced in an acquired firm.There seems to be high level of uncertainity, trust and communication breakdown amoung employees of Kansai Plascon. This research will investigate whether this perception is related to the acquisition transaction that has occurred. The study will collect its primary data using a set of questionnaires that will be distributed to the employees of Kansai Plascon. The data will be analysed and interpreted.

- Description: Organisations within the South African automotive industry (SAAI) are always seeking innovative ways to remain globally competitive. In order to keep costs as low as possible, existing facilities are often adapted to either cater for a wider variety of products or, alternatively, to produce larger volumes than they were originally designed to produce. In every instance, some form of change needs to take place. When the change management processes are defined within the system, quick wins need to be identified. These quick wins may include the elimination of non-valueadding time that is spent moving paper work between offices or ensuring the correct checks are in place to prevent the process from moving to the next step until all the requirements for the current steps have been completed. Technology has been identified as a suitable support mechanism that would be able to integrate into the complex system that comprises processes to be followed in an order that can be predefined. Every organisation faces its own unique challenges when technology is introduced. These can include a lack of computer literacy and the unwillingness to accept that change can in fact benefit the organisation. Getting the users to take ownership of the new systems through comprehensive training initiatives will be shown to be the most effective manner in which to ensure that the systems are effective and used to their full potential. This treatise will investigate the change management systems currently being used in the SAAI and compare the most important factors against the perceived best practices of the resources that are involved in change management. Organisations that operate at various levels within the SAAI will be researched. A literature review of the best practices in change management systems combined with an investigation into how technology can assist in supporting these best practices will be conducted. The findings will then be summarised and recommendations based on the collected data and information will be formulated and put forward.

- Description: In the concluding paragraphs of Keynes’ General Theory, Keynes suggests that vested interests (power) may dominate in the short term, but that “sooner or later, it is ideas, not vested interests, which are dangerous for good or evil” (Keynes; 1936:384). This dissertation seeks to establish whether this is so, and to what extent, in the period 1919 to 1936, insofar as the shaping of monetary policy was concerned. The context that South Africa found itself in at the time was one in which Britain, the colonising power, was in economic decline. Britain’s real economy had lost its lead in the world in the late 1800s, and by our period, 1919 – 1936, she was now struggling to maintain her dominance of the world’s financial economy. South African gold flows to London, and a South African monetary policy supportive of British monetary policy, became more important than ever to Britain. On the back of its ascendant real economy, the United States of America was fast developing its financial sector as a rival to that centered on London. In the broader monetary policy world, the orthodox monetary regime of the Gold Standard, which had worked so well in the period from 1875 to 1914, was firstly difficult to reestablish, and once established, difficult to maintain. Opinion on what should be done was divided between the majority who favoured a return to the orthodoxy, and a much smaller group, including John Maynard Keynes, who argued that the Gold Standard should no longer be the preferred monetary system. In South Africa, our period starts 17 years after the Second Boer War. Afrikaner nationalists intent on establishing independence from Britain, competed with those, including Jan Christiaan Smuts, who believed that tying our policy up with that of the British Empire was the best for South Africa. It is in this context that a naturalised Briton, which the research shows was a loyal servant of the London power elite, was appointed by the Empire-friendly Smuts government to advise the South African government on monetary policy, the setting up of the South African Reserve Bank, the appointment of its first Governor and other matters in the period up until the fall of this government in 1924. It is also in this context that an American ‘Currency Doctor’ and Professor of Economics at Princeton University, which the research shows was intimately connected with the American government and Benjamin Strong at the Federal Reserve, was appointed by the Pact government later in 1924, and who was anxious to throw off the yoke of British control. The theoretical paradigm of this study is that developed by John Maynard Keynes and after him by the post-Keynesian economists, particularly Basil Moore and Hyman P. Minsky. Instead of considering the theory chronologically, book by book, the theory section deals with the subject matter in the themes which came up in the monetary policy debates of the time, looking at all the theoretical literature that applied to these various themes. Aside from the correction of errors of emphasis and errors of fact dealt with in chapter two, chapter five of the dissertation is where most of the original research is reflected. This is the section which deals in depth with the experts that advised the South Africans at the time, how they came to be appointed, whose interests they served, what theories they used in support of their positions, and what was the decision-making process; from their appointment, until their reports were drafted into the law of the Union of South Africa. While Ally’s work (1994) is accepted as the principal work on the influence of the Bank of England, and Britain’s control of South African gold on South African gold and monetary policy, this dissertation claims legitimacy based on a much closer look at the motives and vested interests of the experts advising the South African government at the time. By the end of this chapter, I believe we are better placed to understand and analyse the relative influence of ideas and power on monetary policy in the period 1919 – 1936.

- Description: The aim of this study was to identify membrane biomarkers for colorectal cancer using an insilico and molecular approach. Colorectal cancer (CRC) globally accounts for more than half a million deaths. In South Africa alone, approximately one in 97 men is at risk of getting CRC; and for women, it is one in 162. Novel and non-invasive diagnostic tools, such as biomarkers, are needed for early CRC detection. In order to reduce the fatality rate in this disease, Biomarkers are used as indicators of a biological state; and they are measurable in biological media. They can be used to distinguish between a diseased state and a normal state, thus aiding diagnostics, response to specific therapies, and screening for an early diagnosis. A gene list of potential CRC biomarkers was generated by mining two gene databases, namely: Oncomine and Gene Expression Atlas. A total of 44 candidate genes were identified, based on their location on the cell surface, using the Database for Annotation, Visualisation and Integrated Discovery. These 44 genes were then subjected to an in-depth literature mining. The literature search parameters in PubMed, PubMed Central, Google Scholar and Science direct revealed publications showing that 23 genes were validated, while 21 genes were not validated. Nineteen genes were selected for gene validation in human colorectal cancer and healthy tissue of twelve patients. Total RNA was extracted from 12 colorectal cancer and 12 healthy tissue samples. The RNA was then quantified and reverse-transcribed into cDNA for gene expression analysis. The qPCR running conditions were optimized, by running a melting curve, in order to determine the optimum annealing temperatures. Primarily melt curves were run for nineteen of these twenty-one genes. Melt-curve analysis showed that nine genes were poor candidates for further validation studies; and therefore, only ten genes, namely: AGTRAP, ANKRD46, BACE2, CFB, CIAO1, NOMO3, PTDSS1, SLC5A6, TNFRSF12A and ZDHHC9 were validated by qPCR in human resected colorectal carcinoma and the normal tissues of twelve patients. The qPCR results showed that ZDHHC9 and the SLC5A6 genes were the only two statistically significant ones; and they were found to be down-regulated in human colorectal cancer vs healthy tissue samples.

- Description: The study examined the impact of small scale irrigation technology in crop production under Ncora areas of Cofimvaba. To achieve the objective of the study, data were collected from 212 farmers engaged in various crop enterprises under the Ncora. The farmers were randomly selected. Descriptive Statistics, DEA model, linear regression model and gross margin analysis were used to analyse the results obtained from the survey. The descriptive results showed that Ncora farmers are small-scale farmers cultivating small hectare of land and using simple farm tools, mainly using furrow irrigation. Furthermore, they produce more than one crop enterprises. The gross margin Analysis shows that Ncora cultivation is profitable. The most profitable crop was found to be maize than potatoes. Farm production function revealed that land, labour and purchased inputs had a positive relationship with the output of the enterprises. SPSS was used to run data for linear regression model (OLS). It was suggested that extension services and private organizations assist farmers especially the emerging ones via provision of training, processing and storage facilities. Furthermore, continuous monitoring of soil and water quality as well as ground water table was recommended, in order to ensure sustainability of Ncora irrigation in the area.

- Description: The study seeks to delineate the African socio-political environment through an analytical contextualisation of repetitive authoritative systems, which perpetuate exclusion and the formation of politicised identity. Through a process of historical evaluation of African politics since the majority of states became independent, the study attempts to test a constructed triangular supposition that explains why identity disputation persists at almost every level of African governance. Bearing in mind the almost natural progression of African politics towards identity contestation, the second overriding objective seeks to evaluate the secession of South Sudan as a possible preventative model for identity politicised conflict. In this fashion, the study delves into the politics of a previously unified Sudan; and the events that led South Sudan to eventually seek secession. The primary objective of the study is to evaluate the assumption that territorial secession in Africa is able to quell identity contestation and promote an opportunity for equitable democratic governance. To meet the above objectives, a comprehensive outlay of African socio-politics and governance will be utilised to frame the analysis. Firstly, the study seeks to elaborate on the historiography of African colonial legacy as providing the foundations of identity exclusive politics on the continent. In this way, considerable investigative reverence must be given to the respective policies of colonial administration, namely indirect rule and direct rule. The effects of either of these policies contend a type of socio-political conditioning of African elites and civil society that still persists at time of writing. The concentration of this endeavour will be focused towards indirect colonial policy most famously implemented by British colonialism. The effects of the British policy of ethnic and ethno-religious categorisation is vitally important to a greater understanding of the majority of examples studied in the literature, including the formation of identity contestation in the case of the Sudan. Secondly, to further understand the complex dynamism of African politics which lead to identity based disputation, the study will turn to an analysis of the rhetoric of African independent governance and ideology. The primary objective here will be to detail how differing enactments of African ideology, including the advent of Pan-Arabism to the case of Sudan, ultimately continued the tradition of exclusive citizenship and dominance of some groups over others on the continent. This leads the study to uncover the deeper reasons for why socio-political exclusion continues to the present day. The final dimension of the triangular process suggests that exclusion has been maintained in Africa to prevent access of subverted groups to governance structures and more importantly to the limited resources of African states. Finally, the case of the secession of South Sudan is interpreted through the analytical lens of politicised identity that forms in the face of inadequate state structures to provide legitimate democratic access to the state. The third facet of the proposed theoretical triangle suggests that conflict and contestation is a product of grievances expressed from political exclusion. In this way, it is pivotal to the study to assess whether secession, as in the case of South Sudan, provides a valid alternative platform for suppressing identity contestation and promoting effective democratic consolidation. By all accounts, there is overwhelming evidence already to suggest that secession may be a successful way to repress identity politicisation. However, there remain substantial hurdles for many African states, including a now autonomous South Sudan, in order to finally dissolve the enduring problems of socio-political exclusion. Propositions and possible solutions will be posited for these states as an ad hoc objective.

- Description: The study seeks to delineate the African socio-political environment through an analytical contextualisation of repetitive authoritative systems, which perpetuate exclusion and the formation of politicised identity. Through a process of historical evaluation of African politics since the majority of states became independent, the study attempts to test a constructed triangular supposition that explains why identity disputation persists at almost every level of African governance. Bearing in mind the almost natural progression of African politics towards identity contestation, the second overriding objective seeks to evaluate the secession of South Sudan as a possible preventative model for identity politicised conflict. In this fashion, the study delves into the politics of a previously unified Sudan; and the events that led South Sudan to eventually seek secession. The primary objective of the study is to evaluate the assumption that territorial secession in Africa is able to quell identity contestation and promote an opportunity for equitable democratic governance. To meet the above objectives, a comprehensive outlay of African socio-politics and governance will be utilised to frame the analysis. Firstly, the study seeks to elaborate on the historiography of African colonial legacy as providing the foundations of identity exclusive politics on the continent. In this way, considerable investigative reverence must be given to the respective policies of colonial administration, namely indirect rule and direct rule. The effects of either of these policies contend a type of socio-political conditioning of African elites and civil society that still persists at time of writing. The concentration of this endeavour will be focused towards indirect colonial policy most famously implemented by British colonialism. The effects of the British policy of ethnic and ethno-religious categorisation is vitally important to a greater understanding of the majority of examples studied in the literature, including the formation of identity contestation in the case of the Sudan. Secondly, to further understand the complex dynamism of African politics which lead to identity based disputation, the study will turn to an analysis of the rhetoric of African independent governance and ideology. The primary objective here will be to detail how differing enactments of African ideology, including the advent of Pan-Arabism to the case of Sudan, ultimately continued the tradition of exclusive citizenship and dominance of some groups over others on the continent. This leads the study to uncover the deeper reasons for why socio-political exclusion continues to the present day. The final dimension of the triangular process suggests that exclusion has been maintained in Africa to prevent access of subverted groups to governance structures and more importantly to the limited resources of African states. Finally, the case of the secession of South Sudan is interpreted through the analytical lens of politicised identity that forms in the face of inadequate state structures to provide legitimate democratic access to the state. The third facet of the proposed theoretical triangle suggests that conflict and contestation is a product of grievances expressed from political exclusion. In this way, it is pivotal to the study to assess whether secession, as in the case of South Sudan, provides a valid alternative platform for suppressing identity contestation and promoting effective democratic consolidation. By all accounts, there is overwhelming evidence already to suggest that secession may be a successful way to repress identity politicisation. However, there remain substantial hurdles for many African states, including a now autonomous South Sudan, in order to finally dissolve the enduring problems of socio-political exclusion. Propositions and possible solutions will be posited for these states as an ad hoc objective.

- Description: This half-thesis has developed as a supporting document to an exhibition titled Vabvakure, people from far away, which responds to the growing trends of violence perpetrated against African foreign nationals living in South Africa. This violence which has generally been termed as 'xenophobia' has been framed within this discourse as 'afrophobia', as it is fraught with complexities of race, ethnicity and class. Evidently, not all foreign nationals are at risk but selective targeting of working class black African foreign nationals seems to be the modus operandi. Fanning these flames of prejudice are stereotypes and negative perceptions of Africa and African immigrants that have permeated into the national consciousness of South Africa, which the mainstream media has been complicit in cultivating. My practice is concerned with challenging this politic of representation in relation to the image of the African foreign national within South African society, who have been presented negatively and labelled as the 'Makwerekwere', the 'bogeymen' that have been blamed for the country’s current woes. In response to this, my research adopts the premise that forms of cultural mediation such as visual and performance art can offer further insights and possibly yield solutions that can be used to address these sentiments. As globalisation and neoliberal ideologies reshape the world, there is a growing need in the post-colonial state to revisit and re-construct notions of individual and collective identity, especially that of the nation. Nations, nationalisms and citizenry can no longer be defined solely through indigeneity, for as a result of radical shifts in the flow of migration and immigration policies that allow for naturalisation of aliens and foreign nationals, we are now faced with burgeoning levels of social diversity to the extent that constructions of nationhood that are based on the concept of autochthony have resulted in the persecution of the ‘other’.

- Description: The purpose of the study was to assess the level of patient satisfaction with service provided in the Buffalo City sub-district following the implementation of the down-referral chronic medication distribution system between the tertiary(ELHC) and primary (clinics) levels of health care. The intervention was aimed at improving accessibility and availability of medication to the chronic patients. Research Design: A non-experimental descriptive quantitative research methodology was used. The sampling method for the study was the non-probability purposive sampling. Data was collected using a self-administered questionnaire that was given to respondents as they arrived at the facilities, and who, after completing the questionnaire, gave it back to the researcher. Findings: The results of the study revealed that the patients were generally satisfied about the down-referral chronic medication distribution system. However the patients were not satisfied about the services that they receive from the primary health care facilities when they go to collect their down-referred medication. Lack of communication to the patients regarding their medication by the hospital staff (pharmacists in particular) was a concern for patients. Conclusion: The down-referral chronic medication distribution system can benefit both the patients and the hospitals. Patient will receive their medication closer to their homes and save on the cost of transport. The hospital will have less patient congestion in the outpatient dispensaries and queues and waiting times will be reduced. Some strategies must be sought to improve the services at the primary health care facilities. The hospital should explore various communication methods to put into place, that will save pharmacists time and satisfy the needs of the patients. This would require the health services management from both the hospitals and the primary health care facilities to work together to ensure continued support for the patients.

- Description: The study determined the impact of agricultural development projects on poverty alleviation at Amajuba district municipality. Data was drawn from 100 respondents, projects were purposively selected in line with the focus of projects members and non-projects members in Dannhauser under Amajuba District municipality to access and investigate the impact of agricultural development projects on poverty alleviation. The study presents the results of assessing those that are in groups and those that are working individually on agricultural production to alleviate poverty. The data was captured using a questionnaire which was administered through face-to-face interviews. Descriptive statistics and binary logistic regression model were used to analyse and compare the level of livelihood and variables between project and non-project members. The results show that project members are more productive than non-project members. Project members had more access to funding, training, markets and extension services compared to non-members. However, the results further showed that being a project member attracts some rewards which end up improving the living standards as well as alleviates the poverty levels of farmers, whereas working as an individual limits the farmer(s) from receiving reasonable government assistance such as funding and extension services delivery. The descriptive results indicated that members of most rural households were relatively old, married, literate but unemployed. Non-project members were dependent on remittances, social grants and pension funds because the farming strategy could not meet all their household needs. However, The major crops that were grown for income and food security to maintain their livelihoods include: maize, potatoes, onions, butternut, carrots, cabbage and dry beans. Factors that had significant influences on outcomes were extension services, grants, pension and remittances, land productivity, market accessibility, output difference and livelihood. The available opportunities for project members were access to land, funding, markets, infrastructure, inputs and support services from government institutions, as well as NGO’s.

- Description: Introduction: With batting in cricket, there is no known end point, making the allocation of resources and the development of a suitable pacing strategy more difficult. How batsmen allocate resources and pace themselves when repeatedly sprinting between the wickets is therefore not known. According to the ‘anticipatory feedback’ model, the level of expertise/experience has a substantial influence on the development of a suitable pacing strategy. Skilled or experienced batsmen may therefore have a greater ability to develop and implement a pacing strategy compared to that of novice or less-skilled batsmen. Purpose: To assess whether the absence of a known end point at the beginning of repeated sprint bouts between the wickets effects how batsmen pace themselves comparing skilled and less-skilled batsmen. Methods: Twenty-four male cricketers from a university league were selected. Twelve skilled batsmen (players in the top five batting order), and 12 less-skilled batsmen (players in the bottom five batting order) completed three experimental. All trials required batsmen to complete the same number of shuttle sprints (14 shuttles and therefore 28 runs), while only the information provided before each trial differed. Control Trial: This trial is also referred to as the ‘informed’ trial as the batsmen are aware of the exercise requirements (end point). Unknown Trial: The batsmen were not informed of the exercise end point and were required to run on command for an indefinite period (28 runs). Deceptive Trial: Batsmen’ were incorrectly informed with regards to the number of sprints (told they were only doing 14 runs when in fact they were doing 28 runs). Muscle activity, sprint times and RPE measures were obtained during all three trials and compared. Results: Significant (p<0.05) group effects were apparent for sprint times and, ‘central’ and ‘local’ RPE. Specifically, skilled batsmen obtained the faster mean sprint times, and less-skilled batsmen reported the higher mean ‘central’ and ‘local’ RPE values in all three experimental trials. There were no significant group effects for muscle activation. Skilled batsmen did however have lower muscle activation compared to less-skilled batsmen in all three trials. Furthermore, general trends revealed that sprint times and muscle activation decreased over time (from shuttle 1 to shuttle 14), and RPE (‘central’ and ‘local’) ratings increased, regardless of the experimental trials. Skilled batsmen performed the best in all three trials. This was determined by the attainment of faster sprint times, lower muscle activation and low RPE ratings in each of the three trials. The assessment of the relationship of the dependent variables measured in each trial, did however suggest that skilled batsmen performed best in the deceptive trial while less-skilled batsmen performed best in the control trial. Skilled batsmen thus showed superior performance when trial requirements were unclear. Less-skilled batsmen however, were seen to experience decrements in performance when information regarding the end point was unknown or misleading. Conclusion: It can thus be concluded that previous experience facilitates in the obtainment of improved sprint times between the wickets, especially when the exact end point is unknown.
