- Description: Let me state, from the outset, that the issues raised below may be considered from various vantage points – Capitalism, Marxism, etc. However, this thesis is an endeavour to account for the loss of authenticity due to the most salient features of the consumer paradigm, which is the manufactured object, the production line and the proliferation of said objects. True relationships, or shall we say authentic dialogue, is based upon a difference of viewpoints – or epistemic distance – between the interlocutors. This difference of opinion, it may be argued, allows for a cognitive jostling between the subjects involved and represents, as it were, the reciprocal back and forth movement of ideas that betokens actively engaged dialogue. Crucial, then, to true, and by extension authentic, relationships is an epistemic distance steeped in variegated, heterogeneous points of view. For it is in sharing the differences in our points of view or interpretations of the world that we may start a dialogue far removed from each other and then sustain said dialogue in an attempt to reconcile our differences. The continuation of the dialogue, then, depends upon difference. Without the latter difference, the conditions of true dialogue, which is also a marker of authentic relationships, the need for sustained debate is forfeited and the dialogue ceases to serve a purpose – for the subjects involved in the intellectual jostling and exchange of ideas may already anticipate the thoughts of the other. In so anticipating the thoughts of the other, what is brought to the fore is not the ideas of the other, and by extension the other’s existence distinct from mine, but rather my own existence and thoughts. Were I and the other to share a constellation of beliefs, I am left with only that which I already believe in and so only with my own thoughts. The other’s differing opinion is crucial to their appearing to me as an element discreet and distinct from me. For if the other’s being is in essence of the same ilk as mine – and with that I mean if the other’s points of view and adopted systems of praxis mirror mine – we are like trees in a forest. The existence of collective nouns attests to this latter remark; we are prone to see the forest, not the similar trees that constitute it. Now the question arises as to the constitution of the self; what is it that makes up the character and nature of a person and how, if at all, may subjects be said to differ epistemically? According to Sartre, the ego is a transcendent object for consciousness, meaning that it exists out there in the world just like other objects. This is the case because consciousness is essentially empty. Recall Sartre’s famous claim that existence precedes essence, which in turn means that consciousness, or the ego, is filled up inchmeal with contents outside itself. In other words, that with which we are engaged constitutes the contents of consciousness. Repeated exposure to certain objects, or phenomena, brings about the cultivation of states and qualities – these, as it were, constituting the ego in the end. Moreover, these states and qualities, as arisen from repeated exposure to like phenomena, will instil in the subject a certain proclivity for a certain manner of action under specific conditions. As such, having been presented with something disagreeable many times over, a state of repulsion might gain a foothold in my ego regarding the phenomenon in question. This in turn will dictate how I act in the presence of said phenomenon or any other phenomena that include, adumbrationally, some of the qualities of the original phenomenon. As such, then, my actions are reflections of the states that I experience in the presence of certain objects or phenomena and, it may be argued, reflexively represent the world around me as that which constitutes my ego. The facticity of the world, then, has a great bearing upon the manner in which I perceive and engage the world. However, claims Sartre, facticity is but one side of the coin. The world and its meaning are constituted by what Sartre calls brute meaning. This refers to the fact that meaning is a matter of public opinion and does not precede the phenomenon or object itself – the latter being, in essence, but a bare, pliable, monstrous mass of being-in-itself. Due to this occurrence of meaning being man made, we are in a unique position of freedom. We are, he further claims, capable of transcending these brute meanings, enabling us to avail ourselves of the objects or phenomena in question in a bespoke manner. Freedom to choose how we interact with and interpret the world is thus the ontological ground of choice. We have, on the one side, the world in its undifferentiated state – being-in-itself – and on the other the possibility to give this world a specific meaning in accordance with our intentions – being-for-itself. Freedom to choose, so construed, thus ontologically underlies the very fabric of our existence, hence the claim that we are condemned to be free. Choosing whether to continue along the path set out by our original factual condition or to transcend it and make of it something different altogether is thus not a choice at all, but the obligatory condition of the human condition. Once again, this is the case because consciousness, as per Sartre, is empty to start with and can only be filled with the contents of phenomena or objects in accordance with our intentional engagement of them. However, Sartre continues, this freedom of meaning and the fact that brute existents represent nothing more than the convergence of publicly ascribed meaning awaken in the subject a certain nausea – a nausea born of the fact that we, the people, are at every junction in a position where we have to choose the meaning of life. Determinism, thusly, does not exist and we are not only free to choose the meanings of our own lives, but are responsible for what our lives become. This realisation proves to be too much for most to stomach and leads them along a specific path of choice: over-identification with either their factual realities or with the possibility to transcend the latter. Either way, what they aim to achieve with this overidentification is the suppression of the nauseating reality that reality is nought but what we make it to be and we are thus responsible for what it becomes. Sartre calls this bad faith. Pandering to this proclivity towards bad faith, or alternatively, the propensity for overidentification with either side on the facticity/transcendence dichotomy, we find consumerism. The consumer paradigm delineates happiness as an objective ideal, attainable through the acquisition of specific markers of demonstrable happiness. At the same time, it also provides an answer to the nauseating reality that we, humans, are never fully determined beings, but find ourselves vacillating between our factual constraints and our transcendences thereof. It offers us the crystalised means of becoming this or that individual by way of populating our immediate and personal surroundings with signifiers of happiness. Considering, moreover, that a liberalist conception of human being clearly indicates that individuation of each subject is an important aspect of existence, authenticity in terms of rights emerge as a corollary of said individuation. Each individual, so construed, is given the opportunity, the right, to acquire said markers of happiness and individuation. Obtaining these, it may be argued, allows the individual two things: firstly, to quell the nausea that haunts our dualistic lives by concretising it altogether and so doing highlighting the factual side of things; and secondly, to become discreet and individuated subjects, authentic in their beings. However, the authenticity so begotten provides nought but a thin veneer of idiosyncrasy, as the markers of said authenticity are publicly available and so the same for everyone. The problem, thus, of self-individuation is resolved by providing the subject the means of over-identification with their factual realities whilst convincing them, the consumers, that the objects on offer will afford them a degree of happiness and set them apart from their fellow subjects. The unfortunate upshot of this is that subjects all avail themselves of the same set of objects in an attempt to quell the nausea that besets the individual plunged into an undifferentiated existence. We are here at the heart of the matter. Due to the proliferation of like objects throughout the life-world, a specific system of praxis is implied. So as to navigate the life-world and utilise the similar objects that populate it, consumers are driven towards shared ideologies and courses of action. Moreover, their intentions also converge, as they all seek to establish a web of objects around them that would bespeak their individuation and happiness. Where the life-world has become such a homogeneous landscape, it may be argued, in line with Sartrean thought, that the contents of consciousness would also be similar for all. And where the contents of consciousness is similar for all, we may argue that reasoning would be similar for all. It is at this point that dialogue breaks down, for there is nothing epistemically to separate interlocutors and therefore no differences of opinion to sustain true dialogue. If, as it was reasoned some pages prior, it is the case that sustained dialogue provides the predicate upon which authentic relationships are to be based, the collapse of this epistemic distance between consumers must then also lead to a collapse of authentic relationships. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2022

- Description: Finance is of paramount importance for small, medium and micro enterprises’ (SMMEs) growth, without which many firms fail to move along their growth continuum. Against this background, the study sought to examine the growth effects of financing tools across the different phases of SMMEs' life cycle in Sub Sahara Africa (SSA) economies for the period spanning from 2003 to 2019. Firstly, due to the inherent heterogeneity nature of the SMMEs' financing landscapes across the world, the study starts by identifying the commonly used financing tools in the context of Sub-Saharan Africa. These were found to be internal finance, bank debt, trade credit, non-bank finance and informal finance, with internal finance being the most prevalent financing tool. The second aspect of the study was to examine the growth effects of the identified financing tools on SMMEs' performance in Sub Sahara Africa. In achieving this objective, several panel estimation techniques were employed, which are the feasible generalised least squares (FGLS), cross-sectional dependence (SCC), random effects model (REM) and pooled ordinary least squares (POLS). The empirical results show that internal finance or savings, bank financing, trade credit, non-bank financing and informal financing are positive and statistically significant in explaining SMMEs growth in the region, with stronger evidence for a positive relationship between external finance (trade credit and bank finance) on SMMEs growth in Sub-Saharan African region. The third objective of the study was to investigate the growth effects of SMMEs’ financing tools across different phases of the firm life cycle. The same panel techniques as used in achieving the previous objective were utilized again. The empirical findings show that the growth effects of SMME financing tools evolve as SMMEs move along their growth continuum, and only bank finance proved to be a fundamental variable for SMMEs growth throughout the different phases of firm growth. Finally, motivated by SMMEs’ high dependence on internal finance or savings, the study explored the saving practices of SMMEs in Sub Saharan Africa using thematic analysis. The study findings show that SMMEs in Sub Sahara African economies systematically save through formal and informal financial systems. These findings are contrary to conventional wisdom, which suggests that SMMEs are a financial basket case. Basing on the study findings, policies aimed at reducing or lessening the burden of accessing finance are important to stimulate the growth of SMMEs. Most importantly, there is a need for lenders and sponsors to understand the firm life cycle-financing tool nexus to ensure SMMEs growth. Moreover, SMMEs in Sub Sahara African economies need to cultivate a spirit of thrift to minimize firm attrition rate, thereby promoting SMMEs' growth in the region. , Thesis (PhD) -- Faculty of Management and Commerce, 2022

- Description: This study investigated the extent to which gays and lesbians access quality sexual and reproductive health (SRH) services in Pretoria and Bulawayo. The study also examines the facilitators and barriers for accessing the same services. Theoretically, the study was grounded in the Health Belief Model (Hochbaum, 1958, modified by Rosenstock, 1974 and Siddiqui, 2016). To answer the research questions, a mixed methods approach was applied involving both qualitative and quantitative data collection methods. A total of 30 key informant interviews, eight focus group discussions and 387 questionnaires were administered using purposive, time location and snowball sampling approaches in the two cities. The study found that the most commonly available sexual and reproductive health (SRH) services were contraceptive services, sexually transmitted infections (STI) services and Human immunodeficiency syndrome (HIV) services. The services were provided at public health facilities, drop-in centres and through outreach activities operated by Civil Society Organizations (CSOs). The least available services that gays and lesbians required as part of a comprehensive package were access to information, education and communications (IEC) materials and mental health and psychosocial support services (MHPSS). Several service providers were not adhering to the World Health Organization (WHO) guidelines for provision of comprehensive services for key populations including gays and lesbians. Critical gaps noted included the absence of key populations-only service hours, lack of options for clinicians to attend to them, presence of a stigma and discrimination free environment and provision of comprehensive package of services under one roof. Most of the referral facilities had limited drugs, equipment and supplies for cancer screening and they had no HIV prevention, sex change, in-vitro fertilization, and sterilization services and procedures. The quality of physical facilities and SRH services in both cities did not meet the expectations of gays and lesbians, acting as a barrier to their health seeking behaviour. Stigma and discrimination from healthcare workers was a huge barrier affecting access across all public health facilities. The acts of stigmatisation and discrimination affected the perceptions that gays and lesbians had regarding the quality of the services and compromised access of the same. In view of these health system challenges, the study recommends that there is need for public authorities in both cities to address the bottlenecks and barriers affecting access to SRH services and products such as lubricants, affordable quality condoms, dental dams and latex gloves while reinforcing the facilitating factors promoting access. Healthcare workers need further training on how to provide comprehensive services for gays and lesbians according to the WHO guidelines. Public health authorities in Bulawayo and Pretoria should build upon the identified factors which facilitated the access to SRH services and use of products such as condoms and lubricants. These factors require strengthening of community-based organizations and networks that work directly with gays and lesbians in both Bulawayo and Pretoria. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: Studies on the relationship between funding and efficiency of public universities in South Africa were triggered mainly by the decline of government spending on public universities while the enrolment of financially needy students is increasing. This increase is a product of government’s initiatives to redress the imbalances in access and success caused by the apartheid regime. However, the government seems to be grappling to strike a balance between its initiatives and funding. While the government’s HE transformation initiatives are appreciated, public universities are caught in a dilemma: their revenue is no longer sufficient for the operations given the increase in the number of unfunded and financially constrained students. It is with this background that the study evaluates the efficiency of public South African universities for the period 2009–2016 and how funding composition affects their efficiency. The study contributes to the existing literature in various ways First, a recent study on this subject matter found a decline in the average technical efficiency (TE) score of the South African public universities from 83percent in 2009 to 78percent in 2013. However, the study did not include non-academic staff among other input variables that are assumed to potentially influence performance outcomes of the universities. We therefore developed an argument that a biased conclusion on the subject matter is likely, if academic staff are assumed to dominate efficiency of public universities in South Africa while the efforts of non-academic staff are not considered. Using a Data Envelopment Analysis (DEA) model, the findings of this study revealed that over the study period the average TE of public universities in South Africa increased from 91percent to 95percent. These results suggest that academic and non-academic staff can be deemed as mutually inclusive variables and therefore neglecting either of them can lead to biased estimated average TE scores. The efficiency levels provided in this study can be used as performance benchmarks for identifying potential improvements required to reach a satisfactory level of efficiency. Second, the literature argues that different streams of revenue utilised for funding universities’ activities can provide alternative incentives which might have an impact on efficiency. However, none of the studies examined comparatively the impact of different revenue streams on the efficiency of the public universities in South Africa. Using a fixed-effects regression model, this study found that only traditional universities’ efficiency can be affected by student fees and private income, while government funding does not seem to bear a significant impact on the efficiency of all universities irrespective of their category. Precisely, student fees enhance the efficiency of traditional universities while private income is deleterious on the efficiency of the traditional universities. The study concluded that traditional universities use students’ fees efficiently to deliver quality academic services in a bid to safeguard their reputation and image while revenue from private funders is not efficiently utilised due to the principal-agent problem. In terms of state funding, it was concluded that government spending on public universities is yet to reach a minimum threshold level at which it can contribute significantly to the efficiency of the universities. Third, recent literature used Stochastic Frontier Analysis (SFA) efficiency scores to determine the drivers of efficiency of public universities in South Africa.

- Description: Studies on the relationship between funding and efficiency of public universities in South Africa were triggered mainly by the decline of government spending on public universities while the enrolment of financially needy students is increasing. This increase is a product of government’s initiatives to redress the imbalances in access and success caused by the apartheid regime. However, the government seems to be grappling to strike a balance between its initiatives and funding. While the government’s HE transformation initiatives are appreciated, public universities are caught in a dilemma: their revenue is no longer sufficient for the operations given the increase in the number of unfunded and financially constrained students. It is with this background that the study evaluates the efficiency of public South African universities for the period 2009–2016 and how funding composition affects their efficiency. The study contributes to the existing literature in various ways First, a recent study on this subject matter found a decline in the average technical efficiency (TE) score of the South African public universities from 83percent in 2009 to 78percent in 2013. However, the study did not include non-academic staff among other input variables that are assumed to potentially influence performance outcomes of the universities. We therefore developed an argument that a biased conclusion on the subject matter is likely, if academic staff are assumed to dominate efficiency of public universities in South Africa while the efforts of non-academic staff are not considered. Using a Data Envelopment Analysis (DEA) model, the findings of this study revealed that over the study period the average TE of public universities in South Africa increased from 91percent to 95percent. These results suggest that academic and non-academic staff can be deemed as mutually inclusive variables and therefore neglecting either of them can lead to biased estimated average TE scores. The efficiency levels provided in this study can be used as performance benchmarks for identifying potential improvements required to reach a satisfactory level of efficiency. Second, the literature argues that different streams of revenue utilised for funding universities’ activities can provide alternative incentives which might have an impact on efficiency. However, none of the studies examined comparatively the impact of different revenue streams on the efficiency of the public universities in South Africa. Using a fixed-effects regression model, this study found that only traditional universities’ efficiency can be affected by student fees and private income, while government funding does not seem to bear a significant impact on the efficiency of all universities irrespective of their category. Precisely, student fees enhance the efficiency of traditional universities while private income is deleterious on the efficiency of the traditional universities. The study concluded that traditional universities use students’ fees efficiently to deliver quality academic services in a bid to safeguard their reputation and image while revenue from private funders is not efficiently utilised due to the principal-agent problem. In terms of state funding, it was concluded that government spending on public universities is yet to reach a minimum threshold level at which it can contribute significantly to the efficiency of the universities. Third, recent literature used Stochastic Frontier Analysis (SFA) efficiency scores to determine the drivers of efficiency of public universities in South Africa. Although SFA can control for the stochastic error component in the econometric estimation, the model imposes several theoretical assumptions in the production function which may lead to biased estimations. As a result, several studies on efficiency analysis of Higher Education Institutions (HIEs) around the globe have reverted to using DEA. Using DEA efficiency scores and a Tobit model, this study found that that quality of staff, government funding, student fees, private income, and GDP per capita are positive factors of efficiency while the share of non-white to white staff was found as the determinant of inefficiency. It was concluded that adequate funding and proper management of income by the universities, economic growth and employment of highly educated academic staff can increase efficiency levels of public universities in South Africa, whereas an increase of non-white to white staff in South African public universities is a threat to the universities’ efficiency. Overall, the findings of this study suggest that a cost-sharing framework is inevitable in the South African higher education (HE) system, particularly now that the government is heavily burdened due to the prevailing economic turmoil in the country.

- Description: To investigate the potential anti-diabetic/obesity properties of oral cannabis administration in an obese and streptozotocin (STZ)-induced diabetic rat model, as well as an obese rat model, and to determine the mechanism of action, with a focus on the peritoneal and intramuscular fat depots. Experimental Design: Obese and STZ-induced diabetic rats were allocated a high fat diet (HFD) and intraperitoneally injected with STZ to mimic an obese and diabetic state. The rats were then orally administered cannabis extract (CE) of 1.25, 2.5 and 5.0 mg/kg body weight (relative to tetrahydrocannabinol (THC) content) or metformin as a positive control. For the obese rat model, the rats were allocated either a high carbohydrate diet (HCD) or high fat diet (HFD) and orally administered with cannabis extract of 1.25 mg/kg body weight (relative to THC content). Weight, blood and insulin-resistant parameters of the rats were monitored. The mitochondrial to genomic DNA ratio (MT:18S DNA), average adipocyte area of the various adipose tissues, citrate synthase and carnitine palmitoyltransferase 1 (CPT1) enzyme activities of the peritoneal and intramuscular fat were measured. Gene expression levels of uncoupling protein 1 (UCP1), cell-death inducing DNA fragmentation factor alpha like effector-a (Cidea), perilipin, hormone-sensitive lipase (HSL) and mitochondrial transcription factor A (TFAM) were measured in peritoneal fat, intramuscular fat and brown adipose tissue (BAT). Main Findings: Obese and STZ-induced diabetic rat model: Due to the biphasic nature of cannabinoids, cannabis dosage plays an important role in the observed effects. CE1.25 was the only cannabis treatment effective in improving the insulinresistant parameters of the rats unlike the other higher cannabis concentrations (CE2.5 and CE5.0). In the peritoneal fat, CE1.25 increased MT:18S DNA, increased citrate synthase activity, and decreased the average adipocyte area when compared to the STZ group. CE1.25 also induced fat beigeing by upregulating gene expression levels of UCP1 and Cidea. XIX Furthermore, an increase in gene expression levels of perilipin, HSL, and TFAM showed increased fat mobilization and metabolic activity. In the intramuscular fat, CE1.25 also reduced the average adipocytes area. However, a different mechanism of action was observed where CE1.25 did not induce fat beigeing, but instead increased both citrate synthase and CPT1 enzyme activities and gene expression levels of HSL, thereby indicating increased fat oxidation and mitochondrial activity. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023

- Description: The role of microorganisms in restoration of the Albany Thicket has not been well documented, although the benefits to plants of these various interactions has been well documented. Microorganisms are chief ecological engineers and assist in resolving environmental problems and act to restore degraded ecosystem function by forming mutual relationships with the roots of the plants. The aim of this study was to assess the potential of microorganisms for the improved biomass production of selected woody and succulent seedlings used in mesic thicket restoration. Three tree species were selected for propagation in this study namely; Mystroxylon aethiopicum Scutia myrtina and Aloe ferox. Soil samples were collected from a degraded and intact thicket site from Bathurst, South Africa. Soils were evaluated for number of arbuscular mycorrhizal (AM) spores, mycorrhizal infectivity potential and nutrient availability both before and after seedling propagation. Pasteurized soil from the degraded site was used in a pot trial. Ten replicates seedling for plant species were planted and subjected to four treatments which included inoculation with AM fungi and the rhizobacterium, Enterobacter sp., alone and in combination; the fourth treatment was an un-inouclated control. Plant growth parameters were recorded at regular intervals where appropriate and seedlings were harvested after 24 weeks for biomass measurements and AM colonisation assessments. Although generally low (< 1 spore per gram) the density of AM fungal spores was significantly higher in soils from the intact site when compared with soils from the degraded site. The mycorrhizal potential of the soils was however not significantly different. Mystroxylon aethiopicum seedling shoot height, canopy diameter and shoot biomass showed a significant increase when inoculated with AM fungi while S. myrtina seedlings showed increased shoot height when inoculated with both AM fungi and Enterobacter sp. Aloe ferox seedlings did not respond to microbial inoculation. The concentration of soil P and Na increased in treatments with Enterobacter sp. alone and in combination with AM fungi. Mystroxylon aethiopicum and S. myrtina seedlings showed a dependency on microbial inoculants indicating the importance of inoculation in the nursery before planting out into the field. Overall AM fungal inoculants applied to seedlings can be used to compensate for nutrient deficiency in soils. Although the Enterobacter isolate used was known to have various plant growth promoting capabilities. It is recommended that other rhizobacterial isolates be investigated. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2017

- Description: The mental health of seafarers has become a growing issue of concern and has attracted the attention of researchers in recent times. Seafarers are predominantly men, spend months at sea with little to no contact with loved ones ashore, and usually must reside in confined spaces that often contain substantial levels of noise and heat. The underlying causes of mental illness among seafarers are known. Some of the causes include sleep deprivation, occupational stress, marital/relationship problems, fatigue, the threat of piracy, psychosocial workload, loneliness, social isolation, separation from families, lack of shore leave, cultural issues, and job security. Despite these stressors, there are many men and women seafarers who flourish in the industry and enjoy their careers. Very little research has been conducted into the well-being practices of those seafarers who enjoy high levels of well-being. This study explores the lived experiences of a group of seafarers with reportedly high levels of psychological well-being, as well as their experiences of workplace stressors and mental health interventions offered by the industry. This study is an interpretive phenomenological analysis, which is epistemologically underpinned by phenomenology, hermeneutics and idiography. Results revealed four focus areas: general lived experiences across two worlds and how this relates to identity, what seafarers with reportedly high levels of psychological well-being experience as stressors, well-being practices of these seafarers and how these seafarers experience and make sense of mental health interventions they have come across. , Thesis (PhD) -- Faculty of Humanities, Psychology, 2022

- Description: South Africa together with the rest of the world have been caught up in a new policy wave of developing policies that support the move towards sustainable, low-carbon and climate-resilient economies underpinned by the desire to reduce greenhouse gas (GHG) emissions as per declared Intended Nationally Determined Contributions (INDCs). However, South Africa’s economic development model is still characterised by a coal-based energy structure, which imposes a significant stress on its natural resources and environment, due to vast quantities of GHG emissions into the atmosphere. Currently, in South Africa there is no sign of any coherent plan for achieving the socio-technological change that the transition to a low carbon economy vision implies. The existing policies, strategies and plans are not yet fully aligned with the low carbon transition agenda as they were developed prior to the United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement call. There has been minimal or no noticeable change in South Africa’s carbon-dependence, which may further lead to market failure effects. The existing policy and regulatory framework for low carbon economy (LCE) transition is perceived complimentary; but is defined by short-term, overarching and vague policies that lack forward thinking far-sighted element of framing the desired future. To tackle the short-termism of South African LCE policy, the study commissioned a mixed-method, futures research approach in order to facilitate a kind of forward thinking required for integrated manoeuvres and long-term vision of different alternating choices with a cognisance of their respective repercussions. The primary research objective of this study was to develop and illustrate possible scenarios for South Africa’s low-carbon economy transition futures over the next 30 years, taking into consideration numerous uncertainties about the future structure of South Africa’s economy, costs of the transition as well as potential technological breakthroughs that could emerge. This objective was achieved with the ultimate description of possible futures - Ses’fikile, Stimela, Inqanawa and Siyaya phambili, and the identification of Ses’fikile as the desired future state; as outlined by the Integrated Vision for South Africa’s transition to an inclusive, competitive, climate-resilient and low carbon economy future. Further, the secondary objectives outlined in Chapter 1 and 2 of this research study were realised through an all-encompassing literature review, political economy and political, economic, social, technological, environmental, legal (PESTEL) analysis, the Real-Time Delphi exercise as well as scenario planning methodology. This research study extracts intuitions from academic, policy planning and futures research in order to discover the prevailing frontiers in the progression of both the theoretical and real-world requirements considered as essential for fundamental economic transformation to a low-carbon future. Extensive contribution of this study included; - Closing the literature gaps that exist in terms of gaining a deeper understanding into insights on the potential drivers, impacts and global trends in the low-carbon economy transition space. Pushing forward a narrative within and between the economic development, policy decision-making and environment about how to visualise and plan for a decarbonized future economy for South Africa. Futures research approach afforded this research study an opportunity to engage with the uncertainties of the low-carbon economy future, while engaging with emerging issues, trends and weak signals that are transforming South Africa’s social horizons. Policy decision-makers were afforded a chance to improve their policy making while addressing the dynamic nature of implications of the current economic development trajectories, alternative future possibilities as well as transitioning to a preferred low-carbon future. In conclusion, contributions made by low-carbon experts who participated in this study provided bigger picture insights for policy decision makers and can provide timely interventions while deliberating about South Africa’s low-carbon future. Finally, conclusions drawn and recommendations made would assist in the stimulation of discussions for further policy research.

- Description: This study addresses the problem of abject rural poverty in the post-apartheid South Africa with specific reference to the Amathole Rural District (ARD) in the Eastern Cape Province (the poorest province in the country). Abject poverty is conceptualized as inability to meet the basic human needs such as food, water, shelter and clothes. The study is premised in the revisionist trajectory of rural economic development, which regards agriculture as the ‘engine’ for rural development. The thesis addressed the following issues on rural poverty reduction in the ARD; the efficacy of rural agriculture in rural poverty reduction, value-adding to rural farm produce, support that is required and social factors that may affect the residents’ ability to fight poverty through agriculture? The thesis adopted the concurrent transformative mixed research methodology; and data were collected from a purposive sample of 138 respondents using unstructured interviews and semi-structured questionnaires. Data were collected with the help of research assistance. The study established that the ARD residents were keen to fight abject poverty through rural agriculture but were constrained by the lack of arable land, financial resources, technological support, corruption and HIV/AIDs. In view of the above findings, the thesis concluded that deep collaboration and participation of strategic partners such as government, the rural residents, NGOs and the business sector is essential in the implementation of pro-poor strategies in the ARD. The thesis also called for further research into the following areas that have a direct influence on the efficacy of rural agriculture on the ARD’s development; ICT and development, the rural residents’ attitude towards savings and on the political economy of cooperative ventures in rural agriculture.

- Description: This study addresses the problem of abject rural poverty in the post-apartheid South Africa with specific reference to the Amathole Rural District (ARD) in the Eastern Cape Province (the poorest province in the country). Abject poverty is conceptualized as inability to meet the basic human needs such as food, water, shelter and clothes. The study is premised in the revisionist trajectory of rural economic development, which regards agriculture as the ‘engine’ for rural development. The thesis addressed the following issues on rural poverty reduction in the ARD; the efficacy of rural agriculture in rural poverty reduction, value-adding to rural farm produce, support that is required and social factors that may affect the residents’ ability to fight poverty through agriculture? The thesis adopted the concurrent transformative mixed research methodology; and data were collected from a purposive sample of 138 respondents using unstructured interviews and semi-structured questionnaires. Data were collected with the help of research assistance. The study established that the ARD residents were keen to fight abject poverty through rural agriculture but were constrained by the lack of arable land, financial resources, technological support, corruption and HIV/AIDs. In view of the above findings, the thesis concluded that deep collaboration and participation of strategic partners such as government, the rural residents, NGOs and the business sector is essential in the implementation of pro-poor strategies in the ARD. The thesis also called for further research into the following areas that have a direct influence on the efficacy of rural agriculture on the ARD’s development; ICT and development, the rural residents’ attitude towards savings and on the political economy of cooperative ventures in rural agriculture. The thesis also encouraged further research to establish new linkages and roles of the following pertinent partners in ARD’s development; government, the rural residents, NGOs and the business sector. , Thesis (PhD) -- Faculty of Management and Commerce, 2010

- Description: Psychological assessment forms part of Roman Catholic seminary admissions in Southern Africa. The present study sought to explore and describe the perceptions and experiences of the role, purpose, and nature of the use of psychology in Roman Catholic seminary admissions in the territory of the Southern African Catholic Bishops’ Conference. A qualitative research design was selected, which utilised the grounded theory method. Church authorities and clinicians, recruited by means of purposive snowball sampling, were interviewed in individual semi-structured interviews. The findings were interpreted in relation to the narrative of a vocation to the Roman Catholic priesthood, international practice guidelines, as well as literature regarding the context of the Southern African Roman Catholic Church. Proposed guidelines for this process in Southern Africa were generated based on the experiences of the participants and this iterative process of thematic analysis. Potential guidelines, grounded in the research data, emerged in the following focus areas: the vocation to the priesthood, contextual and systemic factors, the clinician, the assessment process, factors to be assessed, the psychological report, the decision to admit to seminary, feedback, and psychology in formation. These are recommended to the Southern African Catholic Bishops’ Conference in draft form to be implemented in a participatory manner. , Thesis (PhD) -- Faculty of Health Sciences, 2021

- Description: This study investigated the effects of case study teaching on learners’ critical thinking and language literacy skills in Physical Sciences classrooms at secondary school level and whether it could be integrated into the secondary school Physical Sciences lessons without hampering the teaching program. This study is a step in the right direction as it pragmatically attempts to find a constructivism-driven pedagogical strategy that would optimise the attainment of the learning goals of Physical Sciences learners in their various academic settings. To accomplish the research aim, a mixed methods design, in which a non-equivalent (pre-test and post-tests) control-group quasi-experimental design was adopted for quantitative data collection and analysis, and an exploratory case study was adopted for qualitative data collection and analysis. The intervention in the experimental group was case study teaching, whereas in the control group it was the traditional lecture method of teaching science. The topic from the syllabus on which case study teaching was tested was Electricity and Magnetism. The population of the study was all Grade 10 learners studying Physical Sciences in the secondary schools of Sekhukhune East District. The sample consisted of 122 learners from four schools (70 learners from two rural (29 for experimental group and 41 for control group) and 52 from two urban schools (30 experimental group and 22 control group)). Two schools were treated as the experimental groups and the other two as control groups. A multistep sampling process was implemented in selecting the participating schools. Quantitative data was collected using a reading comprehension test, Critical Thinking in Electricity and Magnetism (CTEM) test and a summary writing task that was marked using a Holistic Critical Thinking Scoring Rubric (HCTSR) that was developed by Facione and Facione (1994) and analysed through both descriptive (means) and inferential (two-tailed t-test, Mann Whitney U test and effect size) statistics computed through PSPP statistical pack. Qualitative data was collected through classroom observation (participant observer) in which field notes were kept and face-to-face interviews were conducted, tape recorded and transcribed for analysis. Qualitative data was analysed thematically. , Thesis (PHD) -- Faculty of Education, 2021

- Description: A free press is pivotal to eradication of corruption in the society as the press remains the most powerful channel of communication that cut across all publics. Thus, this study seeks to evaluate the impact of press freedom on reportage of corruption in the oil and gas industry through a content analysis of four Nigerian newspapers (The Punch, Vanguard, Guardian and Nigerian Tribune). The study adopted a mixed research method involving both quantitative and qualitative approaches. Quantitative data were collected and analysed through content analysis of the selected newspapers while the qualitative data collected through interview of the respective newspaper correspondents were analysed using thematic analysis. The study revealed that 534 stories were published on corruption in the Nigerian oil and gas sector by all the newspapers within the study period (July 2018-June 2019), with the Punch having the highest magnitude of stories (n = 196, 36.70percent) while Nigerian Tribune had the highest number of stories reported on its front and back pages (n = 143, 92.25percent). However, Guardian had the highest number of full-paged stories (n = 15, 20percent) whereas the Punch and Nigerian Tribune adopted the widest range of publication formats with news being the most dominant format employed by all the dailies (n = 462, 86.52percent). Although, all the newspapers employed more episodic frame (n = 432, 80.89percent) than thematic frame (n = 93,17.41percent), framing analysis revealed oil theft, vandalism, alleged-fraud, environmental consequences and economic consequences as the major frames used in the coverage of stories on corruption in the Nigerian oil and gas industry. Thematic analysis showed that the newspaper correspondents did not have access to adequate information on corruption in the sector while journalists in the country are still being subjected to intimidation, arrest and imprisonment. These findings suggest that the selected newspapers gave prominence to reportage of corruption in the oil and gas sector in country, which implies that the newspapers are fulfilling their agenda-setting roles and social responsibility in the society. Nevertheless, the level of press freedom in Nigeria has partly affected the reportage of corruption in the oil and gas sector of the country as this has restricted the use of investigative reporting occasioned by the lack of access to classified information on corruption and envisaged harm by potential sources and journalists. Nevertheless, this study proposes an anticorruption-media model, which focuses on the significance of the media as an anticorruption agent in a developing country. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: This research has focused on the synthesis and biological evaluation of a broad range of compounds characterised by the presence of the pharmacologically significant 4-hydroxycoumalin scaffold. The compounds were designed to contain additional pharmachophoric centres to enhance bioactivity and generate lead compounds with dualaction potential. The use of 4-hydroxycoumarin as the primary synthon enabled access to various series of 4-hydroxycoumarin conjugates, the reactive 3-position on the 4-hydroxycoumarin moiety being exploited for regioselective construction of the targeted compounds in several steps. Some of the reactants required in the construction of these compounds were specially synthesised and included propargyloxy benzaldehydes, benzyloxy benzaldehydes and 2,3-dihydroxysuccino-dihydride. Overall, eight different families of novel compounds were accessed, comprising conjugates of 4-hydroxycoumarin with bisethylidenesuccinohyrazide, trifluoroacetamide, amino, benzyloxyphenyl-iminoethyl, benzylidenehyrazinyl-thiazoyl, benzylidenehydrazonoethyl, propargyloxybenzylidenehydrazonoethyl and phenylacryloyl moieties using protocols that required minimal work-up and purification. The eighty novel compounds synthesised in the study were fully characterised using HMRS and advanced NMR techniques. Cytotoxicity, HIV-1 IN and PR inhibitory, and antitrypanosomal, antimalarial and anti-Mtb assays were conducted on the synthesised coumarin derivatives. Several compounds exhibited activity against HIV-1 IN, the most potent being a bis-ethylidenesuccinohyrazide with an IC50 value of 3.5 μM. Various compounds exhibited anti-malarial activity (% pLDH viability in the range 62-77%), anti-trypanosomal activity (the most potent with an IC50 = 0.9 μM against T.b. brucei) and a measure of anti-Mtb activity. Apart from two chalconyl derivatives, none of the synthesised compounds exhibited significant cytotoxicity. Conflicting results were obtained from the in silico docking studies; in some cases supporting the observed in vitro assay data while, in others, exhibiting no correlation. , Thesis (PhD) -- Faculty of Science, Chemistry, 2020

- Description: The practice of strategy implementation is key to the public sector in Zimbabwe because it helps the government to be up to speed in providing services to the public. This research focused on the National Health Strategy 2009-2013 and its impact on health service delivery in Vungu Rural District Council Clinics. The research was based on qualitative desk study design which made use of existing data and semi structured interviews to understand the effect of the National Health Strategy on health service delivery in Vungu Rural Districts Council Clinics. From the literature reviewed and the data collected, it can be noted that lack of resources has had a huge effect on the execution of the strategy. The findings from the study show that the National Health Strategy was a good initiative. However, it lacked financial resources which posed challenges to the health workers in Vungu Rural District Council Clinics. The health workers were not very familiar with the National Health Strategy and this had a negative impact on its execution because they cannot execute a strategy that they are not familiar with. The study highlighted the importance of resources for the execution of the National Health Strategy. The study therefore sought to find ways the Zimbabwean Health System may formulate the health strategy with the limited resources in order to achieve desired goals. The Health Workers echoed the same sentiments that they needed resources for the implementation of the strategy. It is hoped that the findings would provide guidelines for the formulation and implementation of future health strategies. Recommendations given would ensure that there is utilisation of available resources, which would help in the execution of other health strategies to ensure efficient and effective health care service delivery. The recommendations are also intended to enhance the performance of health workers. Though the study was limited to Vungu Rural District Council Clinics the findings and recommendations would provide guidelines for other rural clinics as they use the National Health Strategy. , Thesis (PhD) -- Faculty of Management and Commerce, 2019

- Description: Since the dawn of democracy in 1994 and the subsequent adoption of the Constitution of the Republic of South Africa in 1996, new forms of “wall to wall” municipalities were created throughout South Africa in 2000 and given a mandate of a local developmental sphere. The founding blocks of this was through the creation of the three spheres of government mechanism, namely national, provincial and local, each sphere of government was regarded as distinctive, interrelated and interdependent from one another. The local government sphere however has since mid-2000’s been marred by persistent service delivery protests throughout the country, in recent years the service delivery protests have been accompanied by violence and intimidation. The Eastern Cape Province has not been spared from this phenomenon, media reports, independent monitoring think tanks and yearly statistical results released by the South African Police Service (SAPS) through the ‘Gatherings Act’ indicates that service delivery protests in the province has been on an upward trend on yearly basis since the mid-2000’s. But much more detail is required in understanding the causes behind what are sometimes termed “civil unrest.” The thesis attempts to highlight trends regarding reasons for protest, methods of protest, and the profiling of areas where the protests occur. The findings would meaningfully contribute to the local government discourse and foster alternative mechanisms of engaging communities through better governance and development mechanism by local authorities. The ultimate goal is to create alternative solutions in addressing communities’ needs at local level for policy makers. Currently there is an existing gap in investigating service delivery protests especialy in rural municipalities, most of the municipal research findings and policies are predominantly urban oriented and are not tailor made in addressing rural community’s needs on governance and development. Although the South African Constitution makes provision on steps to be followed on governance and development at local level both vertical and horizontal integration, the Constitution is however silent on addressing governance and development needs of rural communities. As a result of this silence, rural municipalities are confined to develop policies that are not specific to their local needs. Hence the research was conducted in rural communities of Amahlathi and Great Kei municipalities respectively through mixed methods between quantitative and qualitative research. The thesis primarily sought to assess the actual nature and content of forms of engagement in the current public participation discourse at the two municipalities and perceptions thereof of communities on this matter. The information gathered in this research is intended to provide policy makers and those with interests on local government with a better understanding on the dynamics of public participation involvement and service delivery protests on rural based municipalities. The research also seeks to generate new information, insights and perspectives on service delivery protests in order to develop alternative strategies in addressing and minimising service delivery protests. This would assist local government practitioners on the one hand, with planning and implementing a focused approach on governance and development for communities while on the other, introduce an alternative perspective that is evidence based for policy makers. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2015

- Description: In Madagascar, as in several countries in the world, the invasion by four aquatic weeds (Pontederia crassipes Mart. (Pontederiaceae), Pistia stratiotes L. (Araceae), Salvinia molesta D.S. Mitch Salviniaceae) and Azolla filiculoides Lam. (Azollaceae) are among the drivers of environmental and socio-economic deterioration in aquatic ecosystems. Pistia stratiotes was first recorded on the island in the 19th century, and P. crassipes from the beginning of the 20th century, while S. molesta and A. filiculoides were only documented during in the 21st century. From the 1920s, botanists such as Henri Perrier de la Bathie and Raymond Decary were already aware of the dangers caused, in particular by P. crassipes in other countries, and raised the alarm, but little attention has been paid to these species. The aim of the research conducted for this thesis was to determine the distribution, socio-economic and ecological impacts of these four invasive alien aquatic weeds in Madagascar and to make recommendations for their control. First, the distributions of these four aquatic weeds were mapped. This mapping exercise compiled data from different sources including herbarium records, online data and field visits across Madagascar. The mapping study was undertaken from August 2015 to June 2020. Except for mountainous areas above 1800 m (Tsaratanana Massif, Ankaratra Massif and Andringitra Massif) where no data were available, all of Madagascar's bioclimates were invaded by at least one of the four aquatic weeds. In total, at least one species was recorded in 18 of the 22 Regions. Pontederia crassipes was recorded in 13 Regions, S. molesta in 14 Regions, P. stratiotes in 12 Regions, and A. filiculoides in 13 Regions. Herbarium records revealed the oldest record for P. stratiotes to be 1847, 1931 for P. crassipes, 1995 for S. molesta and there were no herbarium specimens for A. filiculoides prior to the start of the current study in 2015. We now know where these four weeds occur and how abundant they are. An objective of this research was to assess the impacts of the four invasive aquatic plants on the socio-economy of the island, mainly on rice production and fishing. Between 2016 and 2019, 102 households in three regions, Soanierana Ivongo, Foulpointe and Antananarivo, were randomly selected and questioned on the impact of these weeds in their aquatic ecosystems and their livelihoods such as fishing and rice growing. Surveys revealed that the four aquatic weeds significantly threatened household activities. On the east coast of Madagascar, the invasions of these four invasive species decreased fish and freshwater shrimp production by 82%. On the high plateau of Madagascar, they reduced rice yield by 30% despite requiring an additional expense of US$ 1,107/ha for control. Although farmers surveyed only used manual control to manage these weeds, they were receptive to other control methods, including integrated control using herbicides and biological control. Another objective of this research was to determine the ecological impacts of the four weeds and specifically if freshwater ecosystem functioning would return after control. To assess the ecological impact, between February 2017 to August 2019, on Lake Antsokafina, the following abiotic and biotic factors were considered: physico-chemistry of water, succession of macrophyte community and animal diversity. With the exception of turbidity, the values of the physico-chemical parameters of the water (pH, electrical conductivity, water temperature and turbidity), were similar between the infested zone and cleared zone. A study on the invasion process of aquatic weeds showed that the plant community succession of the lake changed over time in the areas that had been cleared. The submerged species Ceratophyllum demersum was the pioneer, followed by creeping species such as Echinochloa colona and Ipomoea aquatica, before the area was recolonized by aquatic weeds. Among the aquatic weeds, S. molesta was the most aggressive, covering 92% of the area one year after the start of the experiment. For animal diversity, bird, shrimp and fish community were assessed. The cleaning of the plots in the lake allowed the resumption of fishing activity providing 50 to 200g/catch for shrimp and from 0.25 to 0.5kg/catch for fish per person per day, while no catch was obtained in the areas infested by aquatic weeds were fishermen still attempting to harvest fish/shrimp from the aquatic weed infested areas. Three species of birds, Humblot’s Heron (Ardea humbloti), the white-faced whistling duck (Dendrocygna viduata) and red-billed teal (Anas erythrorhyncha) returned once the areas had been cleared. A manipulated outdoor as descriptor for laboratory experiment was conducted to determine the level and nature of competition of four aquatic weeds species against the indigenous floating fern, Salvinia hastata Desv. (Salviniaceae), using an additive series density model. It was shown that all four invasive species outcompeted S. hastata, with P. crassipes being 24 times more dominant, followed by P. stratiotes at 12 times, S. molesta at 8 times, and finally A. filiculoides at 1.2 times more dominant. This study provided direct evidence of the biodiversity impact of these four species and thus also provided an environmental argument for their control. Based on the findings of this study, a series of recommendations was formulated to manage the invasions of alien species in Madagascar with particular attention to invasive aquatic weeds. These recommendations mainly concern the establishment of management structures and legal instruments such as the creation of a lead government agency at national level and a cross-sectorial invasive species advisory committee, which should review legislation and regulations related to invasive species. , Thesis (PhD) -- Faculty of Science, Zoology and Entomology, 2021

- Description: This thesis intends to contribute to the discourse on global justice as it pertains to resources, the distribution of resources, and the allocation of resources. The focus is on the concept of scarcity. I examine scarcity for how it is understood, interpreted, and applied in the literature on global justice. This thesis argues that scarcity lacks conceptual clarity in the discourse on global justice and argues that if scarcity is misconstrued, the consequences can be severe. Conceptual clarity is thus necessary to ensure that scarcity is properly referred to in the discourse on global justice so that scarcity is not erroneously used when justifications are sought for material deprivation and consequent human suffering. In the process, I will also examine how scarcity is used as a justification in instances of material deprivation and why this is problematic. Given the lack of conceptual clarity regarding scarcity, I argue that reliance on scarcity as justification may be erroneous. The conflation of absolute scarcity and relative scarcity may amount to a category mistake. This thesis purports to clarify scarcity conceptually in the context of global justice. In doing so, I recommend that a resource-centric approach to resource scarcity is adopted to accurately account for the scarcity status of resources. A resource-centric approach to resource scarcity based on a more nuanced understanding of scarcity avoids the potential category mistake. Such an approach ensures that material deprivation and consequent human suffering are not wrongfully attributed to scarcity. , Thesis (PhD) -- Faculty of Humanities, Philosophy, 2022

- Description: In the past two decades, there has been increasing pressure for small-scale inland fisheries to play a central role in food and nutrient security for poor communities in South Africa. For decades, South African inland fisheries have focussed on the exploitation of large fish species and generally ignored the exploitation of inland small fish species (SFS). This research aimed to assess the ecology and small-scale fishery potential of the estuarine round-herring, Gilchristella aestuaria. To understand the ecology of G. aestuaria better, morphometric trait analysis and fish condition of populations in relation to environmental variables (salinity, pH, temperature, turbidity and chlorophyll-a) were done. Fish were supplemented with samples acquired from the SAIAB collection facility for 14 sites to cover all the three South African biogeographic regions, stretching from Lake Sibaya (KZN) to the Orange River estuary in the western parts of the country. The morphometric trait analysis showed that G. aestuaria populations can be distinguished based on the trait variation, however there were many overlaps for populations that are interconnected, with distant/ geographically separated populations showing clear differences. Morphometric traits of the G. aestuaria population were significantly different, however there was no strong directional relationship with environmental variables and variation in morphometric traits. However, fish condition as measured by Fulton’s condition (K) and relative weight (Wr) showed variation between populations found in different environments. These differences suggest that these populations must be managed differently if G. aestuaria is to be exploited in managed fisheries. To determine the potential nutrient value of G. aestuaria to the human diet, samples from two freshwater sites and five estuarine sites were analysed for essential macro and micronutrients. The nutrient content of G. aestuaria revealed there is potential for exploitation, as the species has a high macro (protein and fat) and micronutrient composition (calcium, iron and zinc). Mean ± SD of selected nutrients were protein (61.7±5.0 g/100g), fat (20.4±3.7g/ 100g), calcium (3507.5±314.0mg), iron (40.37±14.0mg/ 100g), zinc (22.47±5.6mg/ 100) and vitamin A (37.3±44.4 RAE/ 100g). The nutrient composition of fish collected from freshwater sites was comparable to those collected from estuarine environments. Using the recommended dietary allowances (RDA) from literature, the mass of fish and the number of fish that would provide a minimum amount for each nutrient were calculated. A child would require only 13.4g of dry G. aestuaria or approximately 74 dried fish to meet the daily requirements of zinc. Other minerals such as iron and calcium also showed a similar low weight or number of fish required to meet daily requirements for the different categories. A small number of G. aestuaria are needed to meet RDA for groups (children, adult men, adult women, pregnant women and lactating mothers). A comparison was done for the nutrient composition of G. aestuaria with reference species that are already harvested for human consumption in some African and Asian countries. The protein content of G. aestuaria was comparable to Chisense (Microthrissa moeruensis) and Kapenta Limnothrissa miodon), while the fat composition was more than twice Chisense and Kapenta. Comparing the mineral composition, G. aestuaria had more than three times higher calcium than Mola (Amblypharyngodon mola) and Puti (Puntius sophore). Zinc composition was four times higher than M. moeruensis and L. miodon. Further exploration of the ecology of G. aestuaria was studied using the Sundays River irrigations ponds as a case study that would represent small impoundments across South Africa. Species rank abundance curve and catch per unit effort (CPUE) on the Sundays Irrigation ponds revealed that G. aestuaria dominated numerically and biomass in the Sundays River irrigation ponds. To assess the potential of harvesting G. aestuaria harvesting experiments were conducted using depletion (removal) sampling. Catchweight (kg) ranged from 2.16 (1.03; 3.28) to 61.25 (44.40; 78.09) kg and the estimated biomass from the depletion model ranged from 1.05 to 40.19 kg/ha for September 2019. The depletion model revealed that small impoundments have high biomass per hectare of G. aestuaria ranging from which indicates that the species may not support a commercial fishery but small-scale fisheries. In conclusion, G. aestuaria could become a meaningful contribution to the food and nutrient security of poor communities where available as a food source through small-scale fishery exploitation. The extent of this contribution may depend on its production potential in various regions and environments. More research is however needed to determine the long-term sustainability of harvesting of G aestuaria by looking at how populations respond to harvesting. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: Gender based violence (GBV) has become a global menace. The prevalence of this violence against women and children in South Africa reveals that the country is plagued by this horror called GBV. According to the South African police crime statistics, with regards to sexual offences, the SAPS reported 64 419 (2012), 66 197 (2014), 62 226 (2013) and 53 617 (2015) cases. A government survey conducted revealed that men were the main perpetrators of this violence. For example, 76 percent of men in Gauteng, 48 percent in Limpopo and 41 percent in KwaZulu-Natal admitted to perpetrating GBV. These alarming statistics calls for the attention of the media. The media is known to be a powerful tool of influence, however in the process, the media has been criticised to portray violence in ways which can have varying effect on the behaviour of those exposed to it. This study was therefore conducted to investigate the perception of the residents of Uitenhage on the media‘s portrayal of gender based violence against women and children. The mixed method of research was used to obtain data from the participants and respondents which were residents of Uitenhage, in the Eastern Cape, South Africa. Non-probability sampling in the form of purposive sampling was used to select the focus group participants while probability sampling in the form of simple random probability sampling was used to select the respondents with whom the questionnaires were administered to. Quantitative data analysis for questionnaires was done using descriptive statistics and findings were presented in form of tables and pie charts while qualitative data analysis for the focus group discussions was done using thematic analysis. A final sample of 257 valid responses were analysed, representing 80 percent response rate, three focus group discussions were also analysed. The study revealed that all the participants and respondents are exposed to more than one medium of mass communication, however participants and respondents opined that the media has both positive and negative effect on different individuals. The study also demonstrated that there is an association between people‘s exposure to the media and their violent behaviour which is attributed to the messages conveyed by the media. The study recommends amongst others that the media should take a more proactive approach to the issue of VAW. , Thesis (PhD) (Communication) -- University of Fort Hare, 2018
