- Description: Giant kingfish Caranx ignobilis, the largest species in the family Carangidae, are global icons as apex marine predators. They are widespread in tropical to subtropical regions globally, where they are of high importance to ecosystems and fisheries. During summer, adults aggregate for spawning, making them vulnerable to overfishing. The world’s largest recorded C. ignobilis aggregation is in southern Mozambique. Some of these aggregating individuals (an unknown proportion) have been recorded passing into South African waters. Furthermore, a unique aggregation of adult C. ignobilis in South Africa’s Mtentu Estuary has attracted global attention but remains unexplained, hence warranting investigation. Research on C. ignobilis globally has shown relatively small home ranges. Research in southern Africa has been limited and inconclusive. Thus, the broad aim of this study is to describe the movement patterns of C. ignobilis from southern Africa. Long-term (36 years) mark-recapture data from the Oceanographic Research Institute’s Co-operative Fish Tagging Project, comprising 3 729 tagged C. ignobilis and 144 recaptures, were analysed. While 74% of recaptures were recorded < 1 km from the tagging location, long-distance movements of up to 419 km were also recorded (mean = 15 km). Although adults moved significantly (p < 0.01) greater distances than juveniles, they also displayed high levels of site fidelity. Seasonal trends included evidence of a summer migration; however, there was still considerable uncertainty regarding exact movements. Therefore, 43 C. ignobilis were acoustically tagged and subsequently monitored along the east coast for over five years with the Acoustic Tracking Array Platform’s passive receiver array. All acoustically tagged adult C. ignobilis migrated to southern Mozambique each year (with minor exceptions), from distances of up to 632 km. When not migrating, South African-based fish showed consistent inter-annual fidelity to individual home ranges. Although coastal home range length (excluding migrations) varied considerably between individuals, even the mean length (92 km) was greater than any previously recorded C. ignobilis home range, globally. In contrast to the southern Mozambique aggregation, the Mtentu Estuary aggregation seems to comprise of individuals showing fidelity to that region. The passive tracking of eight acoustically tagged individuals in the Mtentu Estuary revealed clear trends. Statistical modelling showed that estuarine presence was strongly associated with periods of cold coastal upwelling. Diel movement patterns showed that the utilisation of warm surface waters ~ 4 km upstream during the day was followed by nightly departures to the mouth or sea. Thus, it is likely that this majestic aggregation is for thermal refuge; specifically, for daily re-warming after feeding in cold waters at night. Findings from this study are of global ecological interest and have direct applications for local fisheries management and the development of sustainable eco-tourism. Protecting these vulnerable aggregations is of the utmost importance for the future of this species in southern Africa. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2022

- Description: South Africa, as a post-apartheid state is still grappling with socio-economic inequalities such as poverty, unemployment, and inequality. Local government is mandated to play a developmental role and has a responsibility to redress these socio-economic inequalities at grassroots level. According to the Constitution of South Africa, the local government sphere is obligated to adopt and practice good governance. Whilst good governance means different things to different people, this study argues that good governance is characterised by transparency and accountability, and the use of public resources in an accountable and sustainable manner in order to ensure the progressive realisation of the needs of the municipal residents. This study explores the relationship between oversight and service delivery by examining the Municipal Public Accounts Committee’s oversight of electricity services in Raymond Mhlaba Municipality (herein referred to as RMM) in South Africa’s Eastern Cape Province. It makes use of a case-study research design to inform its data collection and analysis. Officials responsible for electricity service provision and councillors responsible for overseeing the performance of electricity services in RMM were interviewed. These interviews were analysed together with a document analysis of RMM, and a review of relevant local government legislation. The research findings indicate that the Municipal Public Accounts Committee (herein referred to as the MPAC) in RMM failed to engage in effective oversight due to (1) a lack of familiarity with the municipality’s plans for electricity services, (2) a lack of familiarity with the targets for revenue collection and expenditure management for electricity services, and (3) a lack of rigorous oversight and monitoring of the municipality’s spending and implementation of targets set out in its electricity plans. This study, therefore, reflects the realities of non-effective oversight in municipalities in the Eastern Cape and proposes a model which can improve some of the dire oversight practices which are prevalent in rural municipalities such as RMM. , Thesis (MSocSci) -- Faculty of Humanities, Sociology, 2022

- Description: Nearly every philosopher in English-speaking world has heard of Ockham’s Razor, which is given in one of two ways, don’t multiply entities beyond necessity and all things being equal choose the simpler explanation. Yet it is unclear from the scholarship whether the use of Ockham’s Razor is justified in science and philosophy. However, if it can be shown to ‘get’ us truth, it would gain an unequivocal justification, as disputes that are continued after the parties to the substantive truth of one or the other are defined as frivolous. Alternative, one may contend that explanation could have other criteria of success. The implication of a direct connection between the razor and truth comes with ontological commitments, namely a commitment to realism (about universals) and philosophical theism. This is contrary to the razor’s use as a tool of nominalism and naturalism. I argue in this thesis there that the only possible non-circular justification for Ockham’s Razor is truth and that therefore certain philosophical positions are excluded from using the razor to animate their positions. There is an additional, second criteria for the success of our inquiry, namely the justification must in some way be consistent with the razor, which means the chosen explanation for the razor, must be simpler than any of its rivals and not have superfluous entities, otherwise our justification would be contrary to the advice of the razor. We are presented with a Scylla and Charybdis type problem, we avoid a circularity on the one hand and on the other we must not contradict the razor itself, these are contrary intellectual impulses. So firstly I will look at disciplines outside philosophy for some initial inspiration. If we could answer this question in a ‘non’ philosophical way, the problem would have solved itself in a way that require little change of practice. If lawyers or scientist can account for the razor properly, there is not really a problem of justification, at least not a philosophical one. Second, I consider the realist and theist positions, namely an argument of Aristotle’s in the Posterior Analytics and part of Aquinas’ On the Divine Simplicity. Further, I consider the work of Ockham as a nominalist. Lastly, I consider modern and contemporary philosophy, in the form of Hume, Quine and Sober (a modern writer on the razor). The aim here is to ‘stress test’ the philosophical resources of the various systems and analyse the results to see if they can produce a non-circular result. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2022

- Description: Mozambique tilapia, Oreochromis mossambicus, a native southern African species now co-occurs with invasive Nile tilapia, Oreochromis niloticus throughout much of the distribution of the former. The spread of O. niloticus in South Africa has been attributed to escapees from aquaculture facilities, placing O. mossambicus at risk through competition for habitat and food resources, as well as through hybridisation. To better manage invasions, a comprehensive understanding of the biology, ecology and behaviour of both native and invasive species is required. The aim of this research was to comparatively assess the biology of O. mossambicus and O. niloticus, their food resource use characteristics and potential competitive interactions to infer impact risks associated with O. niloticus invasion dynamics. In addition to lack of sufficient autecological knowledge on O. niloticus in general, the challenge in the Eastern Cape is that relatively little regional knowledge is available on the biology and ecology of the native O. mossambicus. To address this, a total of 101 O. mossambicus individuals (32 - 297 mm LT) were sampled from the Sunday River catchment and their age and growth determined using sectioned sagittal otoliths. The largest female was 288.8 mm with a parameter estimate of LT (mm) = 272 (1-e-0.331(t=0.772)) and the largest male was 297 mm described as LT (mm) = 331.9 (1-e-0.167(t=1.192)). The growth parameter estimate age for combined sexes was best described as LT (mm) = 322.5 (1-e-0.201(t=1.027)). The growth rate was initially rapid for O. mossambicus and the asymptotic length reached after four years. The length-at-50% maturity was reached at 106.45 mm LT (R2 = 0.57) for the entire population. There was a significant difference (ᵡ2 = 8,047, df = 1, p-value = 0.0045) in the sex ratio between males and females which was skewed towards males 1:1.89 (F:M). Comparisons with O. niloticus were based on literature and these showed that O. niloticus had faster growth rates than O. mossambicus. These results serve as a baseline study in predicting the potential impacts of O. niloticus if it was to be introduced in the Eastern Cape region. Furthermore, although these two species are known to share habitat and food resources, feeding dynamics within the context of relative impact on prey resources, and competition potential between the species, are largely lacking. I used experimental functional response procedures to contrast the food consumption dynamics of each species and to assess for any multiple predator effects (MPEs) between these two closely related fishes. This was done by contrasting functional responses between individual species under single predator scenarios, predicted multiple predator functional response dynamics based on the individual species outputs, and actually observed functional responses under multiple predator conditions. Results showed that both Nile tilapia and Mozambique tilapia depicted a destabilizing Type II functional response. In both single and conspecific pairing Nile tilapia had significantly greater functional responses than Mozambique tilapia, hence greater overall predatory potential than its native congeneric Mozambique tilapia. Attack rates were also greater for Nile tilapia than Mozambique tilapia with both species showing similar handling times in single trials. However, no evidence for MPEs were detected, given lack of differences between predicted and observed functional responses under heterospecific conditions. These results suggest that Nile tilapia do not adjust their food intake in the presence of heterospecific competitors, but do consume more than Mozambique tilapia and are better at finding food when it is present at low densities. Feeding-related morphological characteristics may influence predatory performance of a species and can further provide information on the species’ capacity to locate, attack and consume different prey items. The feeding capacities between O. mossambicus and O. niloticus were compared based on morphological traits in order to determine whether differences existed, and if these differences place the invasive O. niloticus at an advantageous position in terms of resource acquisition and consumption over its native congener. Principal component analysis for functional morphology traits showed overlap between O. niloticus and O. mossambicus. Oreochromis niloticus had distinctively larger lower jaw closing force, gill resistance and gill raker length which facilitated greater feeding capacities for the invasive species over the native O. mossambicus. Trophic profiles depicted high dietary overlap between the two species. Although O. niloticus had a greater feeding capacity towards phytoplankton, plants, fish (ambush), fish (pursuit) and larvae, while O. mossambicus only showed greater feeding capacity towards zooplankton. While dietary overlap and similarities in morphological traits between native and invasive species may result in exploitative competition between the species, O. niloticus seems to be more versatile in its feeding and capable of consuming food web components that O. mossambicus may not be able to handle. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2022

- Description: Background: Feedback proves to be a valuable tool in behaviour change as it is said to increase compliance and improve the effectiveness of interventions. Interventions that focus on decreasing sedentary behaviour as an independent factor from physical activity are necessary, especially for office workers who spend most of their day seated. There is insufficient knowledge regarding the effectiveness of feedback as a tool to decrease sedentary behaviour. This project implemented a tool that can be used to determine this. To take advantage of the cost-effectiveness and scalability of digital technologies, a mobile application was selected as the mode of delivery. Method: The application was designed as an intervention, using the Theoretical Domains Framework. It was then implemented into a fully functioning application through an agile development process, using Xam- arin.Forms framework. Due to challenges with this framework, a second application was developed using the React Native framework. Pilot studies were used for testing, with the final one consisting of Rhodes University employees. Results: The Xamarin.Forms application proved to be unfeasible; some users experienced fatal errors and crashes. The React Native application worked as desired and produced accurate and consistent step count readings, proving feasible from a functionality standpoint. The agile methodology enabled the developer to focus on implementing and testing one component at a time, which made the development process more manageable. Conclusion: Future work must conduct empirical studies to determine if feedback is an effective tool compared to a control group and which type of feedback (between goal-setting and social comparison) is most effective. , Thesis (MSc) -- Faculty of Science, Computer Science, 2022

- Description: In their efforts for a place in the economy, many South African women have embraced opportunities in the informal sector such as selling products for big Multi-Level Marketers (MLMs), who generally operate on a pyramid structure of commissions. This qualitative study investigates the meanings African women engaged in MLMs in Makhanda make of such work and examines how they construct notions of progress and success through their social media practices. The study was conducted in the strictest lockdown period and pioneered a research method that used Zoom to facilitate screen sharing on mobile phones to create an online version of the scroll-back method for Facebook. As expected for women working in a society increasingly integrated in a global neoliberal order, many of the meanings the women construct are rooted in neoliberal discourses that celebrate hyper-individualism and competition. This firstly includes constructing success through personal stories of self-appreciation, through which these women embody the MLM’s brand, while simultaneously improving their position in the market as sellers. Secondly, the women invest considerable effort on social media in constructing MLM work as epitomising stability in the context of the growing precarity that characterises their everyday lives. However, other meanings draw on the local African context. Here the women make sense of the inequalities that characterise the MLM pyramid structures, by constructing top players in the upline as a symbolic vanguard trailblazing freedom from a racist past through showcasing paths out of poverty. More interestingly, success is constructed as both resulting from and serving collective ways of being rooted in the discourse of African humanism. Here success is recognised as emerging from dense place-based networks in the neighbourhood built on trust and obligation, now replicated on social media. In conclusion, the study speculates that the worlds of meaning facilitated by MLMs might provide ways for neoliberal and traditional discourses to find points of synergy, and so serve as entry points into a neoliberal order that interestingly nevertheless draws on communal cultures of obligation and patronage. , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2022

- Description: The taxation of informal sector business is increasingly becoming a topical issue in many developing countries, and Zimbabwe is no exception. The Zimbabwean government has been experiencing shrinking revenue in the wake of an increased informal sector and a declining formal sector. In an effort to broaden the tax base and increase revenue for government in Zimbabwe, presumptive tax levied against certain informal sector activities was first introduced in 2005 and later expanded to other sectors. Despite the effort, the informal sector has responded with low tax morale and non-compliance, which creates the need to reassess the current administrative strategies in a bid to build a successful tax system for the informal sector. The main goal of the research is to establish clear, innovative and practical administrative strategies that can be adopted by the Zimbabwe Revenue Authority in taxing the informal sector in Zimbabwe. An initial investigation was done to identify the current state of affairs in relation to informal sector taxation in Zimbabwe. A number of challenges were recorded and the research the sought to learn from examples of recent innovation in administrative strategies successfully applied in taxing the informal sector in other jurisdictions like Tanzania and Ghana. Learning from these examples, a number of practical administrative strategies that are mindful of the Zimbabwean economic context were proposed. , Thesis (MCom) -- Faculty of Commerce, Accounting, 2022

- Description: The rise of Social Networking Sites (SNSs) has raised concerns about the negative impact social media platforms, and in particular Facebook, has on their users. Research has linked the excessive use of Facebook with mental health challenges such as loneliness, depression, and stress. This research examined how Yolanda Dyantyi, a gender rights activist registered as a student from 2015 to 2017 at Rhodes University, used Facebook as an outlet following the #RUreferencelist protests and her subsequent permanent exclusion from the institution for her role in the protests. The study explored Dyanti’s use of Facebook, examining in particular her ongoing activism, her mental health challenges, and her struggles to re-establish herself in a community after the exclusion from Rhodes. The study employed an intersectional feminist theoretical framework and drew on a qualitative content analysis, a semi-structured interview, and the scroll back method to review the Facebook posts she had made. A thematic analysis of the data showed that Dyantyi is a multifaceted, and evolving Facebook user and contrary to existing research her prolific use of Facebook has had positive effects on her mental health and has enabled her to build social capital. The study suggests that activism is an important component to research alongside studies of mental health on such media platforms. , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2022

- Description: International trade plays an essential role in economic development strategies. In literature, foreign trade is identified as a driver of economic growth. In recent times there has been an expansion in the scope of investigations around the role of international trade to include its links with poverty alleviation. Poverty alleviation is explicitly identified as the first goal on the 2030 agenda for sustainable development under the Sustainable Development Goals and implicitly defined in goal 10. International trade is seen as the engine behind achieving the goal. South Africa records excessive poverty and inequality levels by international standards for a middle-income country. The most recent Poverty Trends Report for 2006 - 2015 reports 55.5% of the population living in poverty. Inequality statistics reported a per capita expenditure Gini coefficient of 0.65 in 2015, evidence that the country has high levels of inequality. The country's severe poverty, unemployment, and inequality prompt policymakers to formulate developmental policies around the underlying structural challenges. Trade openness has increased since the end of the Apartheid era. Despite the increased trade openness, economic growth has been insufficient in reducing the high unemployment and poverty levels, presenting a challenge for economists, who argue that trade openness is pro-growth and pro-poor. In the South African case, the lack of change in the structural challenges of poverty, unemployment and inequality has raised concerns over whether the trade policy reforms made since 1994 interfere with development objectives. This study aims to investigate the impact of trade liberalisation on poverty, using the three channels, namely enterprise, distribution, and government that have been researched within the McCulloch, Winters and Cirera framework. Specifically, it investigates the linkages via the transmission mechanism in which trade affects poverty in South Africa by mapping the transmission mechanisms from trade liberalisation to poverty alleviation, whilst identifying the possible challenges to the transmission mechanisms and lastly, analysing the stylised facts around trade and poverty in South Africa. To answer the question of this study, quantitative data from National Income Dynamic Study (NIDS) was merged longitudinally and aggregated with the industry tariff data sourced from the World Trade Organisation (WTO) and United Nations Conference on Trade and Development (UNCTAD) statistics. A path analysis was undertaken to map the transmission mechanism, whilst descriptive statistics were used to identify the possible associated challenges. The results show that the most significant channel of transmission are the enterprise and distribution channel. However, the effects are of a small margin and a more comprehensive trade policy yield a higher margin of poverty alleviation. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2022

- Description: Leadership is a key factor in team success. For leadership to succeed, leaders need to possess the requisite competencies that can facilitate their performance. Team skills is identified as a leadership competency that is prioritised and most sought after by leaders. This follows studies that confirm that team skills are vital for leadership and team success. For leadership to develop team skills, feedback must be provided. Feedback is identified as information that is provided by an observer on a particular performance. The role of feedback in leadership development serves the purposes of engagement and self-reflection and evaluation of a leader’s performance. In this light, feedback cannot be separated from leadership as it is an essential part of communication in a leadership context. The nature and source of feedback can affect how the feedback is received, as shown by studies that suggest that the effectiveness of feedback goes beyond the content or nature (good/bad feedback) of the feedback. This study looks at two feedback sources: humans and artificial intelligence (AI) using students as the population. Humans have been the traditional source in feedback provision. Thus, in a team setting peers provide feedback on their peers’ performances. Unprecedented technological advancements have seen the improvement of AI capabilities to being able to give feedback. This has made AI a feedback source. Following these developments, this research assessed the way in which humans and AI provide feedback and the way in which students react to feedback provided by humans and AI. The research used chatbot AI, a Skills Simulator Assessment, launched by Kotlyar (2018). Students registered for Management One at Rhodes University in 2021 were the population for this research. The research was comprised of two phases where in phase one they were assessed by the Skill Simulator Assessment and in phase two they were assessed by their peers. This research found that students are not averse to feedback from AI, although they prefer peer feedback. It was further found that peer feedback tends to be tainted by lenience, while AI is not affected by lenience. This finding marked a significant development of AI in feedback provision. , Thesis (MCom) -- Faculty of Commerce, Management, 2022

- Description: This study aimed to develop a sustainable business model that is cognisant of the fundamental principles of social enterprises that can sustain the operation of the Food for Us mobile application that links farmers with buyers in Eastern and Western Cape, South Africa. The Food for Us mobile application lacks a supporting sustainable social business model to sustain its continued operations, hence the need to develop one. In the study, data was generated qualitatively underpinned by an interpretive paradigm, in three workshops guided by the Delphi method. A stakeholder salience model was applied to identify key stakeholders and their salience. Three key stakeholders, namely users (farmers and buyers), Experts (App developers) and the consortium were identified. The study concluded that developing a sustainable social, innovative business model requires substantive consultation with multiple stakeholders in society. Every stakeholder is important and possesses varying salience, hence stakeholder mapping is an important exercise. The study further concluded that financial sustainability and social inclusion are critical social enterprise elements to consider in the process. The undertaking to enhance financial sustainability opens an understanding on the importance of income streams, the key activities, and value propositions offered by the mobile application. The need to remain socially inclusive brings forth questioning of value propositions, accessibility, user friendliness towards stakeholder diversity and needs. The study offers a solution for the Food for Us mobile application in the form of a prototype which is ready for testing, and if desired results are achieved, this can enhance the much needed continued operations of the mobile application. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2022

- Description: There is a lack of research studies in South Africa that explore young men’s lived experiences of being fathered. The aim of this study focused on exploring how Black South African men construct and understand their own lived experiences of being fathered by their biological father. This research study is situated within a social constructionism methodology and theoretical framework. Data were collected using semi-structured interviews with young men between the ages of 18-24. Data were analysed using thematic analysis as a way of analysing participants’ stories. Three central themes with subthemes emerged. The main themes regarded the father behaviour, fatherly roles and participants’ constructions of fatherhood. The study argues that fatherhood is a social construct based on participants’ lived experiences. Participants in this research still view fatherhood from cultural discourses, such as the provider/protector and a moral guider/role to construct fatherhood. , Thesis (MA) -- Faculty of Humanities, Psychology, 2022
