- Description: ARF GTPases are key regulators of the secretory and endocytic pathways. ARF1 is involved in the secretory pathway. ARF1 has been implicated in the endoplasmic reticulum to Golgi transport, function of the Golgi apparatus and transport from the trans-Golgi network to endosomes. ARFs cycle between active GTP-bound and inactive GDP-bound conformations. GDP/GTP cycling is regulated by large families of guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs). ARF GEFs facilitate the activation of ARFs by mediating the exchange of GDP for GTP, while ARF GAPs terminate ARF function by stimulating the hydrolysis of the terminal phosphate group of GTP. Based on existing evidence gained from gene manipulation and cell biological investigations, ARF1 has been shown to be fundamentally important for cancer cell proliferation and metastasis and may be a promising target for the development of anti-cancer drugs. Additionally, the conservation of ARFs in eukaryotic organisms leads to an interesting question of whether a single drug target can be used to target multiple diseases. In this case, can a human cancer drug employed for cancer therapy be used in anti-malarial drug therapies? To confirm the drug target status of ARFs using chemical validation experiments, novel inhibitory compounds are needed. This requires the development of complex in vitro protein- protein interaction assays that can be used to screen chemical libraries for ARF GTPase inhibitors. In this study, we developed a fluorescence resonance energy transfer (FRET) assay and a novel in vitro colorimetric plate-based assay to detect the activation status of truncated human and Plasmodium falciparum ARF1. In the case of the FRET assay, active (GTP-bound) and inactive (GDP-bound) ARF1 could be distinguished with Z-factor values >0.5, suggesting that further development of the assay format to identify GEF and GAP inhibitors may be feasible. In the case of the colorimetric assay, robust signals could be detected and the assay was useful for detecting the activation status of ARF1. However, although the activation of ARF1 by the Sec7 domains of the BIG1 and ARNO was detectable, signals were not robust enough to employ in screening campaigns.

- Description: This mini-thesis has developed as a practice-based supporting document to the exhibition Chirema Chine Mazano Chinotamba Chakazendama Madziro. The exhibition responds to how people become innovative in finding alternative means of survival and staying relevant in an economically depressed country. Zimbabwe is often the first country that comes to mind when people talk about hyperinflation; the situation was and still is intolerable, but somehow its citizens find means to pull through. Unemployment and poverty are the main causes of physical and mental problems for an individual. With this thesis, I highlight the innovations employed by Zimbabweans as a way of keeping themselves busy. I approach this through analysing the Zimbabwean general public’s creative reactions, and by tracing Zimbabwean visual artists’ use of found objects as a reaction to the country’s economic hardships. As people have been pushed to find alternative ways of survival, Zimbabwean artists in particular also shifted from using conventional art materials due to their unavailability. They began to redefine what art material is by employing objects in their artworks that previously had a non-art function. As such, there is a growing need to recognise, classify and document the shifts and establish platforms to generate growth of these innovations. In this minithesis I discuss my own practice, and I analyse the works of Moffat Takadiwa, Gareth Nyandoro and Serge Attiku Clottey.

- Description: Most construction projects are delayed in the construction industry due to internal and/or external influences. Proving delay is not a simple task but rather a time-consuming process, as projects consist of numerous activities and a substantial amount of detail, and they interface with the many stakeholders. Several different methods can be used to prove a delay; however, these are academic and are mainly for simple projects. Proving a delay is often difficult for the contractor, who is consistently dealing with multiple project constraints. Therefore, to be effective with an extension of time claim, the contractor must establish causation and liability, and assist in demonstrating the extent of time-related damages experienced as a direct result of the delay events relied upon. The process of recording the delays is dynamic and requires solid knowledge of contract clauses, the ability to distinguish between different types of delays and the capability to identify what constitutes valid evidence. Therefore, a need arises to establish a framework that would assist contractors by standardising their submission. This would contribute to expediting the evaluation and approval process, thus limiting the negative impacts associated with prolonged delay claims. The research obtains a “lived” view from contractors who have participated with EOT claims, therefore, utilising the qualitative research method. The choice of data collection method was semi-structured one-on one face to face interviews. In deriving the findings of the research, the coding scheme techniques were used throughout the research process to manage both the secondary and primary data. The main factors which cause major problems in EOT claims are contractual knowledge, lack of supporting information, contractual compliance, employer inference and the different philosophies of contracts, which often leads to confusion and misinterpretation. There is a lack of awareness and knowledge of the analysis techniques and strategies which could assist in preparing EOT claims, even though there is a substantial amount of literature available. The concept that the industry needs a standardised submission process was welcomed by the participants; the existence of a common strategy would certainly resolve many problems in the submission process, including reducing the number of disputes. There was a consensus among all participants that there is no standard approach to submitting EOT claims in the South African construction industry and exploring a common approach was an idea that was viewed as reasonable and maybe offered a practical solution to address the submission challenges. There were several delimitations to this study. First, the sample only included individuals within the Eastern Cape region. Since the sample size was relatively small, the researcher was cautious when interpreting and generalising the results. Secondly, the targeted population for this research was selected using the purposive sampling method, as opposed to a random sampling, which means that the results of the study cannot be generally applied to a larger population. Lastly, the research was a qualitative study which relied on the interpretations of the researcher based on his understanding of the data collected.

- Description: The visually impaired do not have the visual ability to localize objects in three-dimensional space, rather, they rely on their other senses to gain depth perception. Sensory substitution is the concept of substituting one sense for another, normally substituting an impaired sense with a functioning sense. Visual-to-auditory sensory substitution substitutes an impaired visual sense with a functioning auditory sense. This research aimed to investigate and develop techniques for visualto-auditory sensory substitution – using sound localization as a sensory substitution for depth perception. The research started by investigating the characteristics of human audition with a particular focus on how humans localize sounds. It then looked at existing visual-to-auditory sensory substitution systems and the techniques they used. From the existing systems, a system known as MeloSee was chosen as a baseline for developing and evaluating further sensory substitution prototypes. The baseline prototype (𝑃0) was then implemented and a preliminary study performed. Based on the knowledge gained from the preliminary study, baseline implementation and the background research, a set of improvement recommendations were generated. The next iteration – Prototype 1 (𝑃1) – was then developed based on the recommendations. A comparative study between 𝑃0 and 𝑃1 was then performed. Based on the study, another set of improvement recommendations were generated. From the recommendations, a final prototype was developed – Prototype 2 (𝑃2). The last comparative study was then performed between 𝑃0 and 𝑃2, with a third set of recommendations being generated as a result. From the studies it was found that participants using 𝑃0 were able to identify when they were approaching large objects such as walls. 𝑃1 built on that, improving the ability to identify the quadrant of a nearby isolated object. 𝑃2 built on 𝑃0 and 𝑃1, achieving similar results to 𝑃1 for identifying the quadrant of nearby isolated objects, and improving on 𝑃0 and 𝑃1 with regard to depth discrimination – especially for navigation tasks where there were no obstacles. Based on the three sets of recommendations and what was learnt over the course of the research, a set of visual-to-auditory sensory substitution techniques were presented. The techniques aim to be useful for implementing visual-to-auditory sensory substitution systems, which would provide the visually impaired with the visual ability to localize objects in three-dimensional space through sound.

- Description: False codling moth (FCM), Thaumatotibia leucotreta (Meyrick), is the most important pest for the cultivation of citrus in South Africa. False codling moth is indigenous to southern Africa and is a regulated pest of many international markets for phytosanitary concerns. Considerable research efforts have been invested in the past decades to develop semiochemcial technologies, such as monitoring with sex pheromones, attract-and-kill, mating disruption and the sterile insect technique. One of the potential obstacles identified with semiochemical control is the differences in the ratio of the compounds comprising the sex pheromone at different geographical locations, resulting in what is known as regional attraction. This has been identified in FCM populations from three different countries, however, regional attraction within South African FCM populations was unknown. Therefore, the study assessed the genetic integrity of five laboratory-reared FCM populations originating from geographically isolated populations in South Africa using the AFLP technique in order to assess regional attractiveness within the country. The results found isolated populations from Addo, Citrusdal, Marble Hall, Nelspruit and a fifth group found to be closely related to Addo and Citrusdal called the ‘Old’ colony. These five genetically isolated populations as well as a population from Xsit (Pty) Ltd, used for the sterile insect technique (SIT), were used in regional attractiveness trials. Males were significantly (P = <0.05) more attracted to females originating from the same population. No significant attraction could be determined from the sterile males, as the recapture rates in the trap were too low. Furthermore, regional attractiveness was assessed through choice/ no-choice mating compatibility trials. Significant sexual isolation (ISI) occurred between mating combinations Addo × Nelspruit (ISI = 0,13; t2 = 6.23; p = 0.02), Addo × Marble Hall (ISI = 0,11; t2 = 4.72; p = 0.04), Citrusdal × Nelspruit (ISI = 0,11; t2 = 4.95; p = 0.04), and Citrusdal × Marble Hall (ISI = 0,12; t2 = 4.31; p = 0.04). In these combinations, Addo and Citrusdal males were found to have outcompeted Nelspruit and Marble Hall males for more mating events. Significant sexual isolation was also recorded for Sterile × Marble Hall (ISI = 0.12; t2 = 4.98; p =0.01) and Sterile × Citrusdal (ISI = 0.13; t2 = 3.96; p = 0.01) populations. The male relative performance index was significant in both combinations, indicating that non-sterile laboratory males outcompeted the sterile males in these two combinations. When given no choice, evaluated as spermatophore transfer/ female/ 48h, all males (including sterile) were successful in transferring spermatophores to all FCM populations, with no significant differences. These results indicate that there may be incipient pre-isolation mechanisms affected by local natural selection, resulting in localised sexual attraction via differences in the sex pheromone ratios. These findings provide important information for semiochemical technologies and the implication of these results with regard to monitoring with sex pheromones, attract-and-kill, mating disruption and sterile insect technique are discussed.

- Description: Uptake of contraceptives to prevent unwanted pregnancy among sexually active teenagers in South Africa remains low as evidenced by the high prevalence of unwanted pregnancy and unsafe abortions among adolescents. This is happening despite the wide availability of contraceptives which are also offered free of charge and in a context where comprehensive sexuality education is provided from primary school level. There is limited evidence regarding contraceptive use among teenagers in South Africa, which limits the decision making on targeting for promoting use of contraceptives. To address this gap, a quantitative cross sectional study of women aged 13 and above was conducted in Mdatsane Township to investigate the factors associated with contraceptive use among teenagers and compare this with young women aged 20 and above, as well as to assess if there are any associations in the use of contraceptives between the demographic characteristics of the teenagers and their caregivers. The study findings showed that non-use of contraceptives was 53.3%. Teenagers were significantly less likely to use contraceptives, OR 0.31, 95% CI (0.18 – 0.530), more likely to use injectables OR 3.48 95% CI 1.99 – 6.08, more likely to identify partner issues being reason for not using condoms OR 10.60, 95 % CI (2.01 – 55.94). Teenager were more likely to have Termination of unwanted pregnancy on the past (TOP), OR 2.13 95% CI (1.03 – 4.38), and would likely choose Depo/Petogen even if it increases HIV transmission OR 3.65, 95% CI (1.98 – 6.73). Teenagers were more likely to have been exposed to sex education and less likely to have a close relationship with caregivers OR 0.49 95% CI (0.27 – 0.90). In view of these findings it is logical to argue that although teenagers have accessed CSE they have not been able to translate it into action. Hence the need to develop the strategies that can help facilitate behaviour change. Further in-depth studies must be conducted to establish which types of contraceptives are preferred and acceptable to teenagers. Promote self-efficacy of teenagers to be empowered to make own decisions and not put their partners’ preferences on use of contraceptives and continue promoting primary and secondary abstinence while also encouraging delayed sexual debut

- Description: Transformational leadership (TFL) is a leadership theory that describes how leaders create change through their ability to inspire and motivate followers toward self-improvement and innovation that benefits the individual, the group, and the organisation as a whole.This psychobiographical research study explored the leadership style of Richard Branson by using Bass’s theory of transformational leadership. An exploratory-descriptive design was utilised to examine Branson’s life history. He was selected for the study through non-probability purposive sampling based on his history as an extraordinary leader and entrepreneur. Primary and secondary sources of historical and biographical data were used in the data collection process. The data was then processed using thematic analysis against the theoretical framework of transformational leadership. From an ethical perspective, the researcher took care to avoid the misrepresentation of the subject, thus balancing objective research with respect for the psychobiographical content and minimising the risk of doing harm. The findings demonstrated that Branson’s leadership style consists of, and corresponds to a large extent, to the four components of TFL.

- Description: Transformational leadership (TFL) is a leadership theory that describes how leaders create change through their ability to inspire and motivate followers toward self-improvement and innovation that benefits the individual, the group, and the organisation as a whole.This psychobiographical research study explored the leadership style of Richard Branson by using Bass’s theory of transformational leadership. An exploratory-descriptive design was utilised to examine Branson’s life history. He was selected for the study through non-probability purposive sampling based on his history as an extraordinary leader and entrepreneur. Primary and secondary sources of historical and biographical data were used in the data collection process. The data was then processed using thematic analysis against the theoretical framework of transformational leadership. From an ethical perspective, the researcher took care to avoid the misrepresentation of the subject, thus balancing objective research with respect for the psychobiographical content and minimising the risk of doing harm. The findings demonstrated that Branson’s leadership style consists of, and corresponds to a large extent, to the four components of TFL.

- Description: This thesis presents on the synthesis and characterization of novel asymmetric and symmetrical metallophthalocyanines (MPcs) substituted with carboxylic acid functional groups and centrally metallated with zinc and indium. The MPcs are further covalently linked to cysteine capped silver nanoparticles (cys-AgNPs), amino functionalized magnetic nanoparticles (AMNPs) and folic acid (FA) through an amide bond between the carboxylic group of MPcs and the amino group of FA, cys-AgNPs or AMNPs. The covalent linkage of MPcs to FA improved the water solubility of MPcs and allowed for singlet oxygen quantum yield determination in water. Asymmetric MPcs and their conjugates were found to have improved photochemical and photophysical properties compared to symmetrical MPcs and their conjugates. The heavy atom effect of AMNPs and AgNPs improved the triplet and singlet oxygen quantum yields of MPcs. MPcs and their conjugates (MPc-FA, MPc-AMNPs, MPc-AgNPs) were found to have lower in vitro dark cytotoxicity and higher photodynamic therapy (PDT) activity on MCF-7 breast cancer cells. The water soluble MPc-FA had better PDT activity when compared to MPc-AMNPs due to the active targeting of folic acid-folate binding on cancer cell surface. MPcs and MPc-AgNPs conjugates also showed excellent in vitro cytotoxicity on S. aureus under light irradiation compared to dark cytotoxicity. The photosensitizing properties of MPcs and their conjugates are demonstrated for the first time in this thesis, both on breast cancer cells (MCF-7) through photodynamic therapy and on microorganisms (S. aureus) through photodynamic antimicrobial chemotherapy.

- Description: The purpose of the study is to explore and describe challenges experienced by health professionals regarding implementation of the referral system used in Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape Province. A referral system in health care can be defined as a method whereby a health worker with insufficient skills and less resources in the primary health care setting, who has fewer remedies or options to manage medical conditions, seeks assistance from a more senior practitioner in a tertiary setting with better resources to provide guidance in managing the patient or to take over the management of the patient (Eastern Cape Department of Health, 2007:7). A qualitative descriptive explorative contextual design was used to explore and describe the challenges pertaining to the implementation of a referral system in the public health sector in Buffalo City Metropolitan Municipality (BCMM) in the Eastern Cape. A purposive sampling technique was employed with an inclusion criteria of health care professionals who are doctors, professional nurses, pharmacists and specialists. After obtaining ethical clearance from the respective departments, steps for data collection were implemented. Individual interviews were conducted using an interview guide that was prepared by the researcher. Findings in the study indicate that there are challenges in implementing a referral system in relation to infrastructure, workforce capacity, equipment, transport and drug availability. The participants provided suggestions according to their experiences on what they felt the Department of Health in BCMM could do to strengthen the referral system in place. The researcher then provided recommendations to the Department of Health of BCMM. The health referral system in BCMM needs to be strengthened through provision of adequate infrastructure, improving workforce capacity, and availability of medicines and equipment. A monitoring and evaluation plan must be affected by the Eastern Cape Department of Health. Education and training are needed for the health care workers and the community through their involvement in stakeholder meetings

- Description: Financial institutions are faced with increasing competition as there has been an increase in new entrants in the industry, therefore a battle of market share in banking is in progress. Digitization is fast changing how customers perceive value, customers have become spoilt for choice and thus banks have to implement strategies that will help them to increase their market share by keeping the customers they currently have and strategies that help them to acquire more customers. A strategy on its own will not support organizational goals, if it is not adopted by the executers – the employees on the ground. It is important for leaders to support the strategic goals of an organization by ensuring that the goals become a culture, a way of doing things in that organization. This study is an analysis of how leadership shaped a culture of customer centricity in the branch of a bank. The objectives of the study were to: (1) To describe the culture of customer centricity that was cultivated by the branch manager; (2) To analyse what the leader pays attention to, measures and controls on a regular basis, in support of a culture of customer centricity; (3) To analyse how the leader conducts deliberate role modelling, teaching and coaching in support of a culture of customer centricity; (4) To analyse whether - and if so how - the quality of the dyadic relations between the leader and her followers enables or disables the effect of cultural mechanisms on the culture of customer centricity; and (5) To analyse how the leader built high quality relations with her followers The study took the form of a case study of a branch of a bank, where nine universal bankers and their former leader were interviewed. The data were then analysed using a deductive thematic analysis. The findings met all objectives of the study and the findings supported the propositions. The findings also discovered that reward and recognition contributed to the shaping of a culture of customer centricity. In conclusion the limitations and delimitations of the study are acknowledged, and recommendations are made. The study contributes towards the Social Exchange Theory (SET) and demonstrates how high-quality leader member exchange (LMX) relations can be developed. Several recommendations are made for further studies on factors shaping a culture of customer centricity, and implications for management are considered.

- Description: School is a rich source of information about the world, history, nature and its phenomena. Learning is an important part in young people lives and it begins at school. A young person can learn various subjects and facts in schools that would be life-long remembered. Schools can thus be regarded as an important instrument contributing to the positive development of young people.These young people are born into families and in addition to the school the family is regarded as the basic source of strength, nurturance and support for its individual members as well as ensuring stability and generational continuity. Families also play a key role in the development of young people. However, many families struggle with socio-economic issues like poverty, substance abuse and conflict amongst parents and caregivers. The focus of this study is on factors within the school environment that enhance the resilience of high school learnerswhere their experiences of the family’s less than ideal socio-economic situation and challenges create barriers to learning. Literature shows that the school is a place where learners spend the largest portion of their time per day. When learners leave homeforschool, they become the responsibility of the teacher. Teachers in high schools are thus challenged to facilitatereal support to vast number of learners who facedifficult issues in their personal lives. The researcher was interested to know what these young people regard as the factors in school that enhance their resilience despite difficult family circumstances. This study employed a qualitative research approach, embedded in an explorative anddescriptive research design.The sample of the study was drawn from young people who have successfully completed high school. A non-probability, volunteer sampling technique wasemployed to recruit ten young people. They were interviewed using semi-structured interviews. The research ethics such as voluntary participation, informed consent, confidentiality and principle of no harm to participants were adhered to. To ensure the trustworthiness of the data, the researcher observed aspects of credibility, transferability, dependability and conformability. The findings of the study couldcontribute to local knowledge and an increased understanding of aspects of the school that supportresilience-building for young people from challenging circumstances. Young people interviewed in the study came from backgrounds where they experienced various socio-economic challenges, they were able to reflect on strengths in their family systems, personal strengths and how it influences their choices. They also spoke about the positive role the school played in building their resilience and made valuable contributions about how the school can be responsive to students with varying strength-sets.

- Description: Although several languages in the Khoekhoe branch were historically spoken alongside Afrikaans in bilingual speech communities throughout the Western and Northern Cape, the last century has seen abrupt and catastrophic language loss, resulting in a shift from a bilingual to a monolingual paradigm. However, a number of ethnobotanical surveys conducted in the Namaqualand region of the Northern Cape over the last forty years have recorded the retention of Khoekhoe-branch plant names by monolingual Afrikaans speakers. Such surveys make no attempt to source these loanwords to their Khoekhoe-branch targets, do not make use of the standardised Namibian Khoekhoe orthography, and often resort to transcribing loaned click consonants using only ‘t’. This study undertakes a sociohistorical linguistic investigation into the etymological origins and contemporary usage of these loaned plant names in order to develop a clearer understanding of language contact and lexical borrowing in the Namaqualand region. Following the lexicographical compilation of a representative corpus of loanwords, this study conducts a series of semi-structured interviews with monolingual speakers of Namaqualand Afrikaans. Qualitative sociolinguistic analysis of these interviews reveals that, although loanwords are perceived to be of Nama origin, they are semantically opaque beyond pragmatic reference. Preliminary phonological observations identify a loss of phonemic contrastivity in loaned clicks coupled with a high incidence of variability, and suggest epenthetic stop insertion and epenthetic nasalisation as two possible strategies facilitating click loan. Synthesising these ob servations, this study speculates that the use of loanwords hosting clicks may enjoy a degree of covert prestige in Namaqualand Afrikaans, which may in turn shed light on historical sociolinguistic processes of click diffusion. It recommends that urgent and immediate attention be focused on the usage, sociolinguistic status, and regional variation of Nama within the Northern Cape, and advocates strongly for cooperation and improved communication between linguists and ethnobotanists.

- Description: Since the first human-to-human heart transplant in the world was performed by Prof Chris Barnard in Cape Town in 1967, heart transplantation has become the gold standard to treat people suffering from end stage heart failure. This thesis explores heart recipients’ perceptions and experiences of their chronic heart illness before and after transplantation. It examines the medical experience in terms of the clinical diagnosis, the standard of communication about the illness and the proposed treatment, and the post-transplant regime. It also reflects how recipients make sense of heart disease and learn to live with a transplanted heart. The thesis also shows the extent to which the recipients’ culture and individual identity impact such complex medical issues as end stage heart failure and transplantation. Qualitative research was undertaken in private sector heart transplant programmes in South Africa. The study is underpinned by Mishel’s (1990) uncertainty theory as well as by social constructionism.

- Description: Health care facilities in the South African public sector have, over time, become notorious for poor service delivery, peppered with issues of poor governance, weak administration capabilities, and ailing working conditions. Often, the consequence hereof is a loss of good talent to both the private sector and health sectors abroad, all the while placing more strain on institutional service delivery capabilities. To achieve the United Nation’s Sustainable Development Goal (SDG) of Universal Health Coverage (UHC) by 2030, the strengthening of health systems is critical. The purpose of this study is therefore to offer supportable solutions to improve and maintain a sustainable rehabilitation service in the Nelson Mandela Metro through successful retention of staff. The aim of this study then is to investigate the influence that Human Resources (HR) processes, working conditions and leadership have had on retention of staff. A review of the available literature was conducted on possible factors that contribute to the problem and the solutions thereof. The study population included all staff that worked in rehabilitation service departments in the public health institutions in the Nelson Mandela Metro, namely; physiotherapy, occupational therapy, speech therapy and audiology. The sample constituted n=51 respondents. Data was collected via a questionnaire as the selected measurement tool. The data was analysed using the statistical data analysis software system, TIBCO Statistica (version 13), and selected methods for quantitative data. The results of the study showed that only HR processes were significantly and positively (r = 0.67, p < 0.05) related to retention. It means that satisfying the HR needs of this population is most likely to retain their employ and improve and maintain rehabilitation service delivery in the selected metro. Descriptive statistics of all the variables were also calculated and reported on. Lastly, the managerial implications of the study findings were reported on.

- Description: This thesis is concerned with the crisis of xenophobia in South Africa. It argues, firstly, that xenophobia itself is not primarily a reaction to poverty, inequality, or any other set of social conditions. Rather, xenophobia must be considered to be a collective political discourse which has arisen in post-apartheid South Africa from an exclusionary conception of state nationalism. Where this work may be distinguished from the majority of research on xenophobia in South Africa is in the fact that its particular focus is on instances where ‘ordinary’ South Africans have challenged and resisted xenophobic violence in their communities through collective political mobilisation. I suggest that these sites of resistance deserve careful consideration in their own right. I argue that they may demonstrate a subjective break with the oppressive politics of state nationalism through the affirmation of alternative political conceptions. Drawing on the political theory of Sylvain Lazarus, and his principal thesis that people are capable of thinking politics in ways which can subjectively think beyond the social and the extant (underscored by his political and methodological axiom, people think), this thesis argues that these sites of resistance show that people – and especially those who are considered to be marginalised from the domain of legitimate politics – can and do think politically, and it is in the thought of people that new and potentially emancipatory visions of politics may emerge.

- Description: This thesis is concerned with the crisis of xenophobia in South Africa. It argues, firstly, that xenophobia itself is not primarily a reaction to poverty, inequality, or any other set of social conditions. Rather, xenophobia must be considered to be a collective political discourse which has arisen in post-apartheid South Africa from an exclusionary conception of state nationalism. Where this work may be distinguished from the majority of research on xenophobia in South Africa is in the fact that its particular focus is on instances where ‘ordinary’ South Africans have challenged and resisted xenophobic violence in their communities through collective political mobilisation. I suggest that these sites of resistance deserve careful consideration in their own right. I argue that they may demonstrate a subjective break with the oppressive politics of state nationalism through the affirmation of alternative political conceptions. Drawing on the political theory of Sylvain Lazarus, and his principal thesis that people are capable of thinking politics in ways which can subjectively think beyond the social and the extant (underscored by his political and methodological axiom, people think), this thesis argues that these sites of resistance show that people – and especially those who are considered to be marginalised from the domain of legitimate politics – can and do think politically, and it is in the thought of people that new and potentially emancipatory visions of politics may emerge.

- Description: Small to Medium Enterprises (SMEs) have been touted as key enablers to the economic development of most countries. Despite growing evidence that most SMEs fail within their initial years, ICTs have been found to add substantial value in facilitating their success. However, in most developing countries, ICT adoption by SMEs has been plagued with a plethora of challenges ranging from poor electricity supply, high ICT costs, lack of ICT expertise to lack of government support. While this might seem problematic for SMEs, the adoption and the use of cloud services mitigates some of these challenges. The problem, however, is that a limited amount of literature has provided guidance with regard to how the cloud adoption process should be carried out by SMEs. The objective of this research, was therefore, to address this by developing a framework that can be used by SMEs to guide them through the cloud adoption process. To this end, thirteen (13) semi-structured interviews were conducted across nine (9) SMEs in the Eastern Cape. The resultant interview transcripts were analysed using an established thematic approach; the result of which allowed for the development of a rich interpretive narrative about SME cloud adoption. Combined with theory from extant literature, this culminated in the development of a framework for cloud services adoption for SMEs in the Eastern Cape.

- Description: Introduction and Background: Stunting is the most prevalent form of childhood malnutrition where about 149 million children under the age of five can be classified as stunted globally. South Africa has one of the highest stunting rates in the world at 27%, causing devastating effects on economic productivity as well as on an individual’s nutritional status. The presence of stunted growth in children is a strong indicator of chronic undernutrition and highlights injustices experienced within communities. Aims and Objectives: The aim of this study is to develop a stunning profile of children under the age of five, visiting BhishoHospital’s gateway clinic in the Eastern Cape, South Africa. The objectives were to determine the prevalence of stunting of the children visiting Bhisho Hospital’s clinic and to identify the drivers of stunting in the area. Methodology: A quantitative study with a descriptive, cross-sectional design was used. The study population included all children under the age of five visiting Bhisho Hospital’s clinic. Data was collected by means of an interview-administered questionnaire. Results: The prevalence of stunting in the area was 47.5%. A significant association was found between the participants' main form of sanitation and stunting category in the group of infants younger than six months (p = 0.007) and the group older than six months(p = 0.040). Discussion: The prevalence of stunting in the area was far higher than the national average of 27%, although the majority of the sample had a normal weight. The use of non-flush toilets was found to be a risk factor for childhood stunting. Recommendation: Financial and political investment in child health needs to be placed as a top priority in South Africa to reduce stunting rates.

- Description: In the context of tourism, the community is seen as one of many stakeholders, with the other stakeholders being the tourism product owners, the government and tourism marketers. An understanding of a particular community’s perceptions and attitudes and how these perceptions are shaped concerning tourism development is important for decision-makers. The knowledge and involvement of the community in tourism related matters often determine the success of tourism development. The key element of effective planning for tourism is involving the local community and paying attention to their ideas, needs and aspirations, regarding tourism development in their community. Therefore, the aim of this study was to determine Tokyo Sexwale residents’ perceptions of the socio-cultural impacts of tourism in Jeffrey’s Bay. In order to address this aim, the following research objectives were formulated: To conduct a comprehensive literature review on residents’ perceptions of the socio-cultural impacts of tourism; To ascertain the levels of knowledge of Tokyo Sexwale residents about tourism; and To investigate the Tokyo Sexwale residents’ perceptions of the socio-cultural impacts of tourism in Jeffrey’s Bay. In an attempt to address the objectives of this study, a quantitative research approach was adopted. Using the non-probability sampling method, specifically, convenience sampling, the data was collected by conducting the fieldwork in Tokyo Sexwale community in Jeffrey’s Bay from the beginning of June 2019 until the end of August 2019. As a result, completed questionnaires were collected from a sample size of 400 respondents. The findings revealed that 34.7 percent of the respondents were young and aged between 26-35 years. Twenty-seven (27.0) percent of the respondents have been residing in the community for six to ten (6-10) years. A substantial number of respondents had completed a secondary qualification (75.3 percent). The findings further revealed that the majority of respondents were knowledgeable about the statement “Tourism includes holiday trips, travelling away from home for recreational and business purposes” (91.5 percent). Half of the respondents indicated that they interact with tourists more frequently when they visit their area, purchasing goods and services (50.0 percent). With respect to positive and negative socio-cultural impacts of tourism, the findings revealed that 63.5 percent of respondents indicated that tourism has improved the image of Jeffrey’s Bay, while 49.5 percent of respondents indicated that traditional culture is being commercialised as a result of tourism. This study recommends that the local government and tourism businesses in Jeffrey’s Bay should implement community tourism awareness programmes to educate local residents about the potential positive and negative socio-cultural impacts of tourism. This will ensure that local residents of Tokyo Sexwale community are aware of such impacts and reject tourism developments that will be harmful to their community and support those that will benefit them.

First responders’ perceptions of secondary traumatic stress and the screening and referral of trauma survivors at risk of developing posttraumatic stress

- Description: The risk of civilians being exposed to a traumatic event in South Africa is relatively high. This also means that several professional helpers termed first responders, will have frequent contact with individuals who have been traumatized. Working with trauma survivors could have both negative and positive outcomes. On the one hand, first responders’ interaction with trauma survivors provide them with the opportunity to detect when a survivor may be at risk of developing posttraumatic stress disorder (PTSD). Unfortunately, this exposure also puts them at risk of developing secondary traumatic stress with symptoms like those of the trauma survivors they assist. Secondary Traumatic Stress (STS) is relatively well studied among certain helping professions such as therapists, counsellors, social workers and even advocates who work with trauma survivors. Research concerning STS among emergency unit first responders is, however, limited (especially in the South African context). Furthermore, literature investigating emergency unit first responder’s perception of secondary traumatic stress and the screening and referral of trauma survivors at risk of developing PTSD in a South African context appears to be non- existent. The current study aimed to explore and describe first responders’ perceptions of STS and the screening and referral of trauma survivors at risk of developing PTSD. A qualitative design was employed using semi-structured interview questions. The researcher employed a purposive sampling method. As such, only first responders in the emergency unit of general hospitals who regularly work with trauma survivors will be considered for the current study. The data from the interviews was analyzed using thematic analysis based on the principles proposed by Braun and Clark (2006). The findings from this study indicated that while first responders are at risk of developing STS due to the high frequency exposure to traumatic material, very few considered the effects of working with trauma on their mental health. Furthermore, participants in this study reported having inadequate knowledge of PTSD and did not feel confident in screening for trauma survivors at risk of developing PTSD. In addition, participants reported that, while they have previously screened and referred trauma survivors who may be at risk, there was no standard protocol for screening and referring such patients. That being said, the participants did state that should they consider a patient a risk, the hospitals in which they worked did have psychologists on-site.

- Description: Midwives are part of the multidisciplinary team in maternal units and have the bulk of the obstetrical and midwifery responsibilities. The responsibilities being referred to include provision of perinatal care and support to grieving women who have lost their babies at birth and to their families. The care referred to in this study is focused mainly on the grieving women and not on the midwife. By virtue of midwives being present in the event of perinatal loss or caring for a woman who experienced perinatal loss, midwives are compelled to be involved and are bound to experience deep emotions. Furthermore, there is little formal support available for midwives caring for women with perinatal loss in Nelson Mandela Bay Health District (NMBHD) and South Africa at large. The purpose of this study was to obtain a deeper understanding of coping and support needs of midwives caring for women with perinatal loss in the NMBHD. The objectives developed for this study were: explore and describe the facilitating conditions that will enable midwives to care for women with perinatal loss in the in NMBHD; explore and describe the inhibitory conditions that prevent midwives from caring for women with perinatal loss in the NMBHD; identify and describe support needs for midwives caring for women with perinatal loss in the NMBHD and develop coping and support recommendations for midwives caring for women with perinatal loss in the NMBHD. After permission had been granted by the Nelson Mandela university and approval from other relevant authorities had been received data collection was conducted between November 2018 and January 2019, using qualitative research design and interviews. The research population included all midwives working in Midwife Obstetric units (MOUs) and referral hospitals in NMBHD. Purposive sampling was used, and the data collection method was semi-structured and audio-taped in one-on-one interviews with midwives. Sample size was determined by data saturation. The number of participants was thirteen and two of these participants formed part of the pilot study. The collected data was analysed using the seven steps of Framework Analysis from which three themes emerged namely: Midwives rely on their own coping mechanisms vi to deal with perinatal loss; Midwives expressed how management influenced the way they coped with perinatal loss events; Midwives expressed the need for psychological and emotional support. Trustworthiness was maintained by observing Lincoln and Guba’s principles of credibility, transferability, dependability and confirmability. The researcher ensured that the Belmont Report ethical principles were maintained throughout the study. Three main coping and support recommendations for midwives caring for women with perinatal loss in the NMBHD were developed using an adapted version of the AGREE II Tool. The recommendations were: Recommendation 1: Facilitate various forms of peer assistance to prepare and support midwives caring for women with perinatal loss; Recommendation 2: Provide formal support systems in the labour unit to assist midwives to care for women with perinatal loss; and Recommendation 3: Strengthen existing EAPs and provide unit-based psychological and emotional support in order to accommodate the needs of midwives caring for women with perinatal loss.
