- Description: Work means different things to different people and the different meanings they make of their work has the unique ability of contributing to a sense of identity. Support staff have to negotiate their personal identities and social identities to develop a work identity in the complex South African context that has its unique challenges. Exploring how support staff make sense of their experiences, when it comes to their identities, reveals what identity work strategies they use. An interpretative phenomenological method of inquiry was employed as an initial research method to explore the aspects that impact on the identity formation of support staff at Rhodes University. The study aims to investigate how support staff have constructed a work identity through their constructions of their experiences. Six participants were recruited through a purposive sampling method and data were collected using semi-structured interviews. The study revealed that support staff use the following identity work strategies to negotiate their identities: Financial, Personality, Career mobility, Roles, Status and Esteem, Subjective wellbeing. These themes were derived from the narratives of the participants, using the emphases in the data and suggest that support staff use identity work strategies both outside and within the workplace, when constructing their work identities. The study illustrates that as people ascribe different meanings to work, they will define and negotiate their identities in the workplace based upon those meanings. Identity work is indeed challenging for support staff because they need to use identity strategies that are enhancing to their self-esteem. Identity work is a challenging task because of the many tensions and demands of modern society, as adults negotiate their needs to provide for families and to find ways to construct their job status in positive ways. , Thesis (MA) -- Faculty of Humanities, Psychology, 2021

- Description: Water scarcity is recognised as one of the significant challenges facing many countries, including South Africa. The threat of water scarcity is exacerbated by the coupled impacts of climate and anthropogenic drivers. Ongoing droughts and continued land cover change and degradation influence the ability of catchments to partition rainwater runoff, thereby affecting streamflow returns. However, quantifying land degradation accurately remains a challenge. This thesis used the theoretical lens of investing in ecological infrastructure to improve the drought mitigation function in rural catchments. This theoretical framework allows for a social-ecological systems approach to understand and facilitate science-based strategies for promoting ecosystem recovery. Specifically, this study aimed to explore the role and benefit of ecological infrastructure for improving drought mitigation, and consequently, water security for rural communities. Thus, this study sought to assess the consequences of human actions to catchment health status using the 15th Sustainable Development Goal indicator for the proportion of degraded land over the total land area as a surrogate. Secondly, hydrological modelling was used to describe how different land covers influence catchment hydrology, which related to how ecological infrastructure enables drought risk-reduction for mitigation regulation. Finally, this study developed a spatial prioritisation plan for restoration to improve drought mitigation for four focal ecological infrastructure (EI) categories (i.e. wetlands, riparian margins, abandoned agricultural fields and grasslands). The focal EI categories were selected for their importance in delivering water-related ecosystem services when sustainably managed. Chapter 1 sets the scene (i.e. provides the study background) and Chapter 2 provides a review of the literature. In Chapter 3, the recently released global GIS toolbox (TRENDS.EARTH) was used for tracking land change and for assessing the SDG 15.3.1 degradation indicator of i.e. Cacadu catchment over 15 years at a 300 m resolution. The results showed a declining trend in biomass productivity within the Cacadu catchment led to moderate degradation, with 16.79% of the total landscape degraded, which was determined by the pugin using the one-out, all-out rule. The incidence of degradation was detected in middle reaches of the catchment (i.e. S10F-J), while some improvement was detected in upper reaches (S10A-C) and lower reaches (S10J). In Chapter 4, a GIS-based Analytic Hierarchical Process (AHP) based on community stakeholder priorities, open-access spatial datasets and expert opinions, was used to identify EI focal areas that are best suitable for restoration to increase the drought mitigation capacity of the Cacadu catchment. The collected datasets provided three broad criteria (ecosystem health, water provision and social benefit) for establishing the AHP model using 12 spatial attributes. Prioritisation results show that up to 89% of the Cacadu catchment is suitable for restoration to improve drought mitigation. Catchments S10B-D, and S10F, S10G and S10J were highly prioritised while S10A, S10E and S10H received low priority, due to improving environmental conditions and low hydrological potential. Areas that were prioritised with consideration for local livelihoods overlap the areas for drought mitigation and form a network of villages from the middle to lower catchment reaches. Prioritised restoration areas with a consideration of societal benefit made up 0.56% of wetlands, 4.27% of riparian margins, 92.06% of abandoned croplands, and 51.86% of grasslands. Chapter 5 reports on use of the Pitman groundwater model to help understand the influence of land modification on catchment hydrology, and highlight the role of restoration interventions. The Cacadu catchment is ungauged, therefore the neighbouring Indwe catchment was used for parameter transfer through a spatial regionalisation technique. Results suggest that degradation increases surface runoff and aggravates recharge reduction, thereby reducing streamflow during low flow periods. In areas where there is natural land cover recovery, the Pitman Model simulated similar dry season streamflow to the natural land cover. Combining the outcomes from the three assessments allowed the study to highlight the role and benefits of ecological infrastructure in terms of drought mitigation. Study findings were interpreted to make recommendations for the role and benefit of ecological infrastructure for drought mitigation at a landscape scale and tertiary catchment level, within the context of available management options. The results support the notion that multiple science data sources can promote investments in ecological infrastructure. However, better spatial and temporal resolution datasets at a national level are still needed to improve the accuracy of studies such as the one outlined in this thesis. The study recommends adopting better ecosystem protection approaches and collaborative governance at multiple levels to reduce the vulnerability of rural communities to drought impacts. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2021

- Description: Throughout the world, urbanisation is at an all-time high. It is estimated that two-thirds of the global population will be living in urban centres by 2030. The highest urban growth rates are currently found in sub -Saharan Africa, however, approximately 70% of urban residents in Sub-Saharan Africa reside in informal settlements. Such processes have resulted in reduced areas of natural space and biodiversity. While the benefits of exposure to and experiences of nature to human well-being and quality of life are increasingly being acknowledged, these links are largely understood through a western lens, where nature and culture are dichotomised. The implications of this are that the types of nature(s) that are made available in urban areas are designed to provide opportunities for urban residents to only engage in recreational and relaxation activities within such places. However, among indigenous and non-westernised communities, culture is a dynamic and holistic entity, deeply rooted in the constructions of nature. Very few studies from the global south have entered this dialogue. In response, this study, conducted amongst Xhosa speaking urban residents living in two medium-sized towns, was undertaken to explore the connections and meanings they attributed to nature(s) and how their engagement in such places contributed to their sense of well-being. This study found that strong connections and meanings to nature still exist. Many of these relate to personal experiences which are given meaning through local understandings and associations which are deeply embedded within cultural practices and rituals. Engagement and or memories of such are strongly associated with a sense of well-being often only experienced in rural areas. In such contexts, well-being is also understood as a holistic concept that is underpinned by these nature-culture connections. Within an urban context, the benefits of such connections are hindered by the types of nature(s) found in these areas as well as high levels of crime and the poor management of such places. , Thesis (MA) -- Faculty of Humanities, Anthropology, 2021

- Description: The South African abalone, Haliotis midae, is a commercially important species of mollusc which contributes significantly to the value of the South African mariculture industry. One of the primary challenges experienced by abalone farmers is the consistent production of juvenile abalone (spat) in sufficient volumes to keep stocking farms and facilitate expansion of the industry. One of the key production bottlenecks of H. midae is achieving adequate levels of larval attachment and metamorphosis (settlement). The larvae of H. midae are settled on polycarbonate plates which have been pre-conditioned with biofilms in seawater which is pumped ashore onto farms. The seasonal variability in settlement success reported by hatchery managers in South Africa is hypothesised to be as a result of different diatom species compositions colonising the settlement plates at different times of the year, with settlement success being lowest during the winter months. The following study investigated whether the addition of conspecific mucous to biofilms could result in elevated settlement success, and whether there was potential for sterilisation of this mucous. A novel method of mucous application, spraying it onto the plates as opposed to pre-grazing, was tested in settlement assays and the trials revealed the following results: • The addition of H. midae mucous induced significantly more larvae to attach to settlement plates, when mucous was harvested around the spawning season. • Elevated attachment of larvae on mucous treated plates did not result in more post-larvae occupying the plates at the end of trials, and increased mortality is likely attributed to introduction of pathogens in conjunction with mucous. • No increase in the final proportion of settled larvae which had metamorphosed or the rate at which they metamorphosed was observed between mucous application treatments and biofilm only treatments. Subsequent trials assessed whether methods of mucous handling could reduce the biosecurity risk associated with mucous use, and so mucous was either UV irradiated or autoclaved. These trials revealed the following findings: • No difference in attachment was seen between any treatments, including the untreated mucous. This is contrary to the findings of our initial experiments and illustrates that the attachment-inducing properties within mucous may be seasonally expressed. ii • Numbers of observed larvae/post-larvae on plates applied with UV and autoclaved mucous where less stable than biofilms only, especially in the second trial, illustrating that mucous still presents a biosecurity risk even after undergoing these handling methods as it may act as a substrate on which pathogenic bacteria could colonise. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: Cyclopia spp. is used for the production of Honeybush tea, an herbal tea which is used in many cases as a substitute for rooibos tea. The wild harvesting of this fynbos plant still brings in up to 85% of the annual crop and as such needs to be carefully monitored in order to avoid over harvesting and the destruction of biodiversity within the Eastern and Western Cape mountain regions of Southern Africa. Due to the concerns of overharvesting and unsuitable use of the wild resource issues of supply security have been raised. There is a lack of formal knowledge relating to the plant, its harvesting, the industry and its economic potential. This study aimed to amend this scarcity by contributing to the knowledge of C. subternata as a wild harvested plant, the physical environment favoured by C. subternata, sustainable use through harvesting of the wild plant and harvesting methods specific to this honeybush species. The research concludes by presenting a guideline for best harvest practices of the wild C. subternata plant. , Thesis (MSc) -- Faculty of Science, Department of Geography, 2021

- Description: This study took place in the context of a growing racialised global water crisis and increasing demands worldwide for transforming higher education at institutions of ongoing settler colonialism. It presents a conceptualisation of what education, research and activism can look like and unfolded inside a doctoral research project that expands what doctoral education can look like. Using a media arts-based praxis process, I developed a relational model of university curriculum –site-specific, media arts-based, environmental education –with potential to cultivate relations (human and nonhuman) towards reconciliation while contributing to justice at the water-climate change nexus. My aim as a settler-ally was to expand my teaching and curriculum practices, thereby also offering curriculum transformation inspiration to others. My research was rooted in my concept of reconciliation as a practice towards thriving together, where the ‘together’ was inclusive of both humans and nonhumans. The curriculum engaged students in de/re/constructing water narratives through making site-specific videos focused on local water bodies. Decolonising artistic approaches known as slow media and soundscape recording were strategically incorporated into audio/video mapping assignments where students observed water aesthetics in ways that shifted their perceptions about water and entities entangled with it. Students met with Knowledge Keepers (Indigenous and non-Indigenous people from outside the academy with existing relationships to water bodies). A photovoice methodology was used in these meetings with Knowledge Keepers to reconfigure traditional film director-subject power relations. Guest lecturers from non-traditional backgrounds contributed diverse perspectives. Ecomotricity was incorporated, whereby students were in deliberate movement in/with water bodies through canoeing together. The curriculum culminated in a public screening/education event where resulting videos, interspersed with educational games facilitated by students, surfaced emotions, knowledge co-production and new synergies amongst the event’s temporary community. Through two iterations of the curriculum, where I co-designed and taught a course called Making Waveforms, one in Vancouver, Canada and one in Cape Town, South Africa, I explored the primary research question: How can a relational site specific, media arts-based university environmental education curriculum cultivate students’ relational sensibilities and abilities oriented towards reconciliation of diverse peoples and ecosystems in South Africa and Canada? Iterating the curriculum across these two contexts allowed me to assess which aspect(s)of the curriculum may have been applicable across these and other contexts. By using mixed methods of data collection and sharing throughout the research journey, I explored the sub-questions: a) How is reconciliation understood currently by university students in South Africa and Canada? and b) How can a relational site-specific, media arts-based university environmental education curriculum and my PhD methodologies (PhD-by-publication, website, and participatory approaches to podcasting, video making, and song creation), contribute to decolonising higher education, and thereby further contribute to reconciliation of diverse peoples and ecosystems in South Africa and Canada? Integral to my praxis process, I undertook a PhD-by-publication that involved writing four academic journal articles, with each paper presenting a key stage in the process. The papers, all of which have been submitted to peer-reviewed academic journals, form part of this thesis and can be found in the Appendices. The course was originally developed around Donati’s (2011) relational sociology and Gergen’s (2009) relational education theory. Throughout my praxis process, I expanded my theoretical influences as called for by the research and teaching practice. The journey behind my first PhD paper, (Towards) Sound research practice: Podcast-building as modeling relational sensibilities at the water-climate change nexus in Cape Town, began when I officially started my doctoral studies in early 2018. The paper was co-authored with a fellow PhD scholar from Rhodes University’s Environmental Learning Research Centre (ELRC), Anna James. It presents an experimental arts-based methodology we co-developed for doing contextual profiling by building a socially-engaged podcast series, called Day One, to explore the lived experiences of the Cape Town water crisis of 2018. It includes my initial tool of analysis for exploring how the curriculum might cultivate relational sensibilities and abilities towards reconciliation. The podcast pedagogy offered opportunities to develop some relational learning processes. The analytical tool was developed from cross-referencing reconciliation and relational educational theories. This paper also incorporated theories in relational solidarity and social movement learning. The podcast episodes included personal narratives that, in turn, revealed diverse ideologies and polarisations in the water situation. Working with the audio medium highlighted possibilities for creating and shifting affective relations. Recording and editing soundscapes of waterbodies began explorations of the agential qualities of water. These were foundational dynamics to explore in building the reconciliation curriculum. The paper is published in the International Journal of New Media, Technology, and the Arts (2019, Volume14, Issue1). My second PhD paper, A media arts-based praxis process of building towards a relational model of curriculum oriented towards reconciliation through water justice, presents my methodology for and analysis of a pilot course I co-designed and taught at the Emily Carr University of Art + Design (ECUAD) in Vancouver, Canada in 2018. This course served as contextual profiling around the water situation in Vancouver. The course was offered in partnership with a science-based environmental non-profit called the David Suzuki Foundation and an Indigenous-led post-secondary school called the Native Education College. The course’s public event was hosted at the Beaty Biodiversity Museum. At this stage, I was introduced to Cree/Métis filmmaker, Gregory Coyes, and his Indigenous cinematic narrative approach known as Slow Media. Integrating slow media into video mapping assignments presented exciting possibilities for shifting views and valuing of water. This was the stage at which my concept of reconciliation expanded to explicitly include nonhumans. I applied my initial analytical tool to the curriculum here, which revealed the three most prominent relational sensibilities and abilities towards reconciliation cultivated by students through the course: (1) knowledge ecologies; (2) a hopeful social imaginary; and (3) embodied ways of knowing. I began to make connections between the curriculum and Mi’kmaq elder Albert Marshall’s concept of ‘Two-Eyed-Seeing’, and expanded the notion to ‘Three-Eyed-Seeing’ to include artistic approaches. Deeply inspired by Bekerman and Zembylas’s (2012) Teaching Contested Narratives, I began to see the growing importance of the narrative aspects of reconciliation education. The paper is published in the University of Pretoria’s Journal of Decolonising Disciplines (2021, Volume 1, Issue 2). My third PhD paper, Water as artist-collaborator: Posthumanism and reconciliation in relational media arts-based education, presents a 2019 iteration of the curriculum at ECUAD in Vancouver, and illustrates my shift to include posthuman theories in my analysis. This course was offered in affiliation with the David Suzuki Foundation, and in collaboration with the Native Education College. The culminating public event was hosted by the Beaty Biodiversity Museum. Decentring the human in this data analysis better supported my research and curricular aims. The strong technoculture of the media arts-based curriculum fits well with many posthuman concepts. This posthuman reading of the course and data enabled me to see what changes were emerging through student-water-technology intra-actions, and how these supported relations towards reconciliation as well as water justice. Most notable of these changes was the emergence of water’s agential qualities, specifically of water as becoming collaborator in artistic/knowledge co-production, where students think with water. I argued this contributes to reconciliation by decentring the human, enabling relations in which power is more equal, and where there are greater possibilities for mutual responsibility between related entities. This is where I developed the concept of audio/video as relational texts, supporting the creating and shifting of affective relations more than the monumentalised verbal/written knowledge of traditional universities. This is also where I realised that relational work towards reconciliation would require engaging with the hidden curriculum of institutions. The paper is published in the journal Reconceptualizing Educational Research Methodology (2021, Volume 12, Issue 1), as part of a special issue on Posthuman Conceptions of Change in Empirical Educational Research. My fourth PhD paper, originally entitled Making waveforms: Implicit knowledge representation through video water narratives as decolonising practice towards reconciliation in South Africa’s higher education, presents an analysis of the 2019 iteration of the curriculum in South Africa. I co-designed and led a course called Making Waveforms at the University of Cape Town’s Future Water Institute (FWI) in collaboration with Rhodes University. The course was co-designed/facilitated with FWI’s Research Fellow Amber Abrams, who also co-authored this paper. The course’s public event was hosted by a non-profit organisation called the Tshisimani Centre for Activist Education. This paper explored the ways that non-verbalisable, implicit learning –understood as part of many non-Euro/Western ways of knowing– takes place in the Making Waveforms course and how this influenced water-specific climate behaviours while contributing to decolonised reconciliation practice for higher education institutions. Drawing on theories of implicit and explicit knowledge, we first showed how implicit learning primarily took place through: 1) site-specific audio/video mapping of water bodies; 2) meetings with Knowledge Keepers; and 3) an interactive public screening event. We highlighted how this non-verbalisable learning produced feelings of empathy for diverse peoples and waterways, as well as aesthetic appreciation of water, and how this can contribute to more response-able water behaviours. This, we argued, supported the valuing of implicit knowledge within a traditional educational setting, thereby pluralising knowledge, and was key to reconciliation/decolonisation in higher education. Iterating the curriculum for the South African context emphasised the importance of context-specificity of the course overall, and also of the relational work embedded in the curriculum. This paper is under review by the University of Toronto’s journal Curriculum Inquiry (CI). Following receipt of CI's internal review process, the title of the paper has since been updated to Non-verbalisable, implicit knowledge through cellphilms as decolonised reconciliation practice towards response-able water behaviours in South Africa. Through reflective analysis of my four papers, I developed a concept for an Anatomy of Decoloniz/sed Curriculum consisting of five key parts: 1) relationality; 2) multimodality; 3) narratives/counter-narratives; 4) context-specificity; and 5) unhidden curriculum. Four meta reflections have been included in this thesis, each corresponding with one of the four papers, and presented chronologically according to the stage of the praxis process with which they correspond. In these meta reflections, I applied Kolb’s (1984) Experiential Learning Cycle model for reflective writing, based on the premise that through experiences we can expand our understanding, and included four key stages: 1) concrete experience; 2) reflective observation; 3) abstract conceptualisation; and 4) active experimentation. For the concrete experience, I provided a thick description of my process in writing the paper, as well as aspects of the phase in my praxis process that was the focus of the paper, not included in but relevant to the paper. For the reflective observation, I identified any aspects of the experience that were new to me and which therefore presented opportunities for me to learn. For the abstract conceptualisation, I critically analysed my concrete experience and reflective observation to determine which, if any, of the five key parts of the Anatomy of Decoloniz/sed Curriculum that I outline in my introduction relate to this phase of my PhD praxis process. For the active experimentation, I made conclusions about the extent to which this phase of my PhD embraced decoloniality in practice, and built on this new understanding to make recommendations for myself and others committed to the decolonial project as part of my contribution to knowledge. These meta reflections also invite readers to follow my personal narrative of becoming-with water, meaning my transformation from being water illiterate to embracing a ‘watershed mind’ (Wong,2011). Multimodality, which I propose as a key part of an Anatomy of Decoloniz/sed Curriculum, is embedded in the representational aspects of this thesis. The courses I co-designed and taught as part of this project resulted in the creation of 20 short student films. My contextual profiling involved a podcast methodology that was ongoing throughout my study, as a model of decolonised research-communication-education-action at the water-climate change nexus. This methodology resulted in the creation of four Day One podcast episodes, co-produced with a PhD colleague, Anna James. Some of these episodes are available in all three main languages of Cape Town (Xhosa, Afrikaans, and English). I evolved the podcast methodology in a later stage of my praxis process as a form of member checking with contributors involved in various stages and aspects of the research. Once the four papers were written, I created a series of four short videos called In the Flow, with each video representing a translation of one of the four papers. I invited various contributors of the research project to either watch one or more of the In the Flow videos and/or read one or more of the academic papers, and then to respond in a Zoom call with me. The responses were then shared publicly in a series of seven Climate for Changing Lenses podcast episodes. Parts of these are included in a final song/music video called Please Don’t Blow It. A Climate for Changing Lenses website was created to host all of this multimedia content that forms part of this thesis. A link to this website is provided in the Introduction section of this thesis. My research contributes to the advancement of knowledge in the areas of relational and reconciliation pedagogy, decolonising higher education, arts-based teaching, learning and research methodologies and the water-climate change nexus. My praxis process provided a relational model of reconciliation curriculum that has been tried and tested in two international contexts: Canada and South Africa. , Thesis (PhD) -- Faculty of Education, Education, 2021

- Description: This half-thesis reports on an ethnographic investigation of the implementation of the Bilingual-Bicultural Approach for educating Deaf learners, focusing on South African Sign Language (SASL) teaching at the Further Education and Training (FET) level in a South African School for the Deaf in the Eastern Cape. The investigation occurs within the context of the introduction, in 2015, of the SASL Curriculum and Assessment Policy Statement (CAPS) by the Department of Basic Education (DBE). The SASL CAPS introduces an approach to teaching the Deaf known as the Bilingual-Bicultural Approach. This is an approach in which natural sign language (such as SASL) is taught first and used to learn a spoken language such as English for reading and writing. Previous research on a contrastive analysis of South African English and SASL reveals that SASL is a Topic-Comment language. It is sometimes Object-Subject-Verb (OSV) or Subject-Object-Verb (SOV) while the word order of South African English is Subject-Verb-Object (SVO). Semi-structured interviews of hearing and Deaf participants reveal serious tensions between the staff and the hearing staff because Deaf culture is not adhered to by some of the hearing staff. These tensions have a negative impact on the culture of learning and teaching at the school. Observations of four lessons at an FET class taught by an SASL FET teacher show that in her teaching, SASL syntax is used in keeping with the principles of the Bilingual-Bicultural Approach. However, her signing is accompanied by unvoiced spoken language due to the influence of a previously used approach called Total Communication (TC). One of the learners, Lulu, who contributes considerably more often than other learners in the lesson, also shows the same influence of TC. Other learners are either withdrawn or copy signs from Lulu. The study concludes with the recommendation that SASL be used for initiating newcomers to school as opposed to Signed English because research in bilingualism suggests that second language learners need one natural language established first before attempting to learn a second language. Teachers are recommended to immerse themselves into Deaf culture to acquire fluency. Comments from some participants suggest that teachers require vigorous training in the Bilingual-Bicultural Approach on a continuous basis. , Thesis (MA) -- Faculty of Humanities, Linguistics and Applied Languages Studies, 2021

- Description: In South Africa different species, from the genus Crataegus, including Crataegus monogyna Jacq and C. mexicana DC have been introduced for various reasons in the past. Populations of these plants have now established in multiple provinces. However, the invasive status, risk and insect pollinators that promote their reproduction and dispersal have never been studied in South Africa. This study was aimed at 1) Assessing the risk of, and mapping two Crataegus species, Crataegus monogyna Jacq and C. mexicana DC in South Africa, 2) Determining the role and effectiveness of insects pollinators to fruiting of C. monogyna and C. mexicana, 3) Identifying flower visitors of C. monogyna and C. mexicana, and 4) documenting potential dispersal vectors for both species in the Eastern Cape Province. A framework entitled “Framework and guideline for conducting risk analysis under NEM: BA Alien and Invasive Species Regulation of 2014” was used to assess the risk of the two Crataegus spp, and we conducted field trips to various provinces in SA to map their distribution. The author conducted an exclusion experiment to determine the role and effectiveness of insect pollinators. Observations were conducted to identify flower visitors and potential dispersal vectors for both species. The risk analysis results suggested that both species pose a high risk of becoming invasive in South Africa. The eradication feasibility of both species was found to be medium with C. monogyna having an eradication feasibility score of 5 and C. mexicana having an eradication feasibility score of 4. This meant that there was a 50 percent chance for both species to be eradicated in South Africa currently. After a thorough risk analysis, it was recommended that both species be listed under category 1b on the National Environmental Management Biodiversity Act. Category 1b species are invasive species that need to be controlled, and if possible, they must be eradicated, trading of species from this category is not allowed. Crataegus mexicana was found to be widespread in South Africa with ten relatively small populations distributed in 5 provinces; Limpopo, Mpumalanga, KwaZulu-Natal, Free State and Eastern Cape Province. Crataegus monogyna was found not to be widespread in South Africa, with only three populations found in the Eastern Cape Province. Insect pollinators contribute to the fruiting of both species in SA. However, the exotic plants were also observed to be able to self-pollinate when insects are excluded. Flowers of C. monogyna were visited by various insect species from orders Lepidoptera, Hymenoptera, Coleoptera and Diptera, while C. mexicana is visited by species from the order Hymenoptera, Diptera, Lepidoptera and Coleoptera. Seventy-seven percent (77 percent) of potential dispersal vectors observed for C. monogyna were birds, and 15 percent were mammals. For C. mexicana, 71 percent of potential dispersal vectors observed were mammals, and 29 percent were birds. Crataegus monogyna and C. mexicana are emerging invasive alien species in South Africa, and not much is known about them. Although the two species are listed as invasive weeds in South Africa, very little is known about their invasive status in other parts of the world. This study has managed to give baseline information and data about both species which are already in South Africa. The baseline information and data include the population structure of both species, their distribution, the risk they pose to South Africa biodiversity and their reproduction ecology. Currently, there are no management plans in place for both species in South Africa, and this is because they are not listed yet in the National Environmental Management Biodiversity Act of South Africa. However, this study recommends that current populations continue to be monitored, awareness of both species in various provinces be initiated to help in the discovery of new and emerging populations, and management options of large populations developed in the future. , Thesis (MSc) (Entomology) -- University of Fort Hare, 2021

- Description: In South Africa different species, from the genus Crataegus, including Crataegus monogyna Jacq and C. mexicana DC have been introduced for various reasons in the past. Populations of these plants have now established in multiple provinces. However, the invasive status, risk and insect pollinators that promote their reproduction and dispersal have never been studied in South Africa. This study was aimed at 1) Assessing the risk of, and mapping two Crataegus species, Crataegus monogyna Jacq and C. mexicana DC in South Africa, 2) Determining the role and effectiveness of insects pollinators to fruiting of C. monogyna and C. mexicana, 3) Identifying flower visitors of C. monogyna and C. mexicana, and 4) documenting potential dispersal vectors for both species in the Eastern Cape Province.

- Description: The Southwest Indian Ocean (SWIO) islands of Mauritius and Seychelles are both highly dependent on tourism and fisheries for their economies. One of the growing ecotourism sectors is saltwater fly fishing, an industry based on catch-and-release fishing for a host of species, including bonefishes. Bonefishes (Albula spp.) have received significant research attention in the Pacific and Atlantic Oceans, with only sporadic research conducted in the Indian Ocean. My project aimed to investigate the genetic connectivity of the roundjaw bonefish (Albula glossodonta) in two island states (Seychelles and Mauritius) within the SWIO using a mitochondrial genetic marker (cyt-b) and next generation sequencing (ddRADseq). Samples collected were grouped based on their spatial distribution. The Seychelles consisted of four island groups (Inner Island Group, Aldabra Group, Amirantes and Alphonse Group, and Farquhar Group) whereas Mauritius was represented by one island group (Saint Brandon). Genetic analyses were undertaken between and within each of these groups. Mitochondrial cytochrome-b identified two species of bonefish: Albula glossodonta and Albula oligolepis; the latter was only genetically identified from the Inner Island Group. I hypothesise that this is due to habitat partitioning, with A. oligolepis being a deeper dwelling bonefish species compared to A. glossodonta, which occupies shallow water habitats such as sand flats, atoll lagoons and reef flats. Neutral SNP loci revealed a panmictic pattern of distribution for A. glossodonta throughout the Seychelles Island groups but showed a pattern of weak structure between Seychelles and Mauritius. Genetic diversity indices such as allelic richness, showed low diversity across the sampling sites (AR range: 1.761-1.889). Population structure tests such as pairwise FST showed low but significant population structure. The highest FST indices were recorded between the Aldabra and Farquhar Groups, as well as the Aldabra and Saint Brandon Groups (0.044 ± 0.000 and 0.040 ± 0.000, respectively). Descriptive tests such as PCA and DAPC showed similar trends, whereby Saint Brandon clustered separately from the other samples from the Seychelles Island groups. However, these trends were Abstract seen at very low variations (PCA axes 1 and 2 accounted for only 2.0 and 1.9 % of the total variation, respectively). A population assignment test grouped the individuals as one ancestral population. A spatial principal component analysis showed that Saint Brandon was dissimilar to the Seychelles Island groups. Like other Elopomorph species, bonefishes have leptocephalus larvae capable of long-distance dispersal which may explain the well-mixed genetic population observed within the Seychelles islands. Although currents within the Indian Ocean, especially on a mesoscale, are not well understood, the South Equatorial Current likely facilitates connectivity between the Seychelles islands while also limiting gene flow between Seychelles and Mauritius. Understanding population structure is important for informing the appropriate management and conservation strategies, especially in oceanic nations where data informing important industries like tourism and fisheries are often limited. The bonefish fly fishing industry is well-known to be a lucrative sector, generating, for example US$ 1.4 million a year in the Bahamas. This study recognised that there are numerous knowledge gaps relevant to the bonefish industry that need to be addressed, including: 1) understanding the socio-economic importance of fly fishing to island states like Seychelles, 2) estimating the abundance and species distribution of bonefishes within Seychelles, 3) understanding effectiveness of MPAs for recreational fishery species like bonefish and, lastly, 4) generating more fishery-relevant biological information on the heavily targeted fly fishing species within Seychelles. These needs must be met to inform management plans and to better manage the fly fishing ventures that target species like bonefish. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: The Pericles Citizenship Law of 451 made citizenship contingent on an individual man having Athenian blood on both his father and mother’s side. Men with foreign mothers were denied any rights to the key institutions that conferred Athenian belonging, such as deme and phratry membership, as well as, of course, citizenship. When, however, the Peloponnesian War began in 431, the population of Athenian citizens was quickly diminished by military conflict and plague and they sought a solution to repopulate their numbers with as little change to the original law as possible. The result was an amendment in 429 allowing citizens with no living legitimate (γνήσιοι) heirs to legitimise their bastards (νόθοι) in their place. A year after this, Euripides wrote the Hippolytus, a play that deals very closely with the issues of bastardy, bastards’ place in the polis and the oikos, and their treatment by those who are legitimate. As the war went on, he proceeded to produce two other plays containing bastard characters, the Andromache (c.425) and the Ion (c.413), in which he similarly explored the consequences of illegitimacy. In all three plays his attitude towards bastards is overwhelmingly sympathetic and the way he chooses to present their situations suggests his disagreement with the arrogance and antipathy that continued to push many of these often very worthy individuals to the fringes of society. This thesis seeks to examine Euripides’ presentation of bastards through a close reading of the relevant texts, in order to understand how the plays reacted to the contemporary circumstances of and what comments they are making. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2021

- Description: The persistence of personal identity stands at the heart of many human practices, such as paying individuals for their work or holding people responsible for their actions. As such, it seems important that theories of personal identity are able to account for the practical implications of continuity of personal identity. Mindful of the practical importance of personal identity, Marya Schechtman (1994) argues that her narrative view only accounts for the four features that persons must possess. Any account of personal identity is supposed to make persons capable of possessing these features. She then posits her narrative self-constitution view as an account of personal identity she feels is capable of explaining the link between personal identity and certain features of persons. In this thesis project, I present how the narrative views, as described by Schechtman and others, are interpretive enterprises and that this leads them to a potentially devastating conclusion. The narratives must be constructed from something, and I argue that it is memory. But empirical facts about memory do not allow for it to persist in a quantitative way, but rather in a qualitative way, much like persons. Upon making this argument, I further argue that if mainstream psychological views is correct, this reduces the persistence of memory to resemblance relations. And memory is the building blocks of narrative. If this is the case, then narrative is also reduced to resemblance relations. Narrative, therefore, does not persist through time in a non-qualitative way, and one is better off accepting a psychological theory by virtue of parsimony. Ultimately, I argue that Schechtman and narrative theorists may save narrative views by adopting what I call as a ‘causal narrative view’. A causal narrative view will encapsulate all of the relevant features of the typical narrative view, including the emphasis on construction, but will also add the addendum that narrative states must be placed in a causal relation to each other. , Thesis (MA) -- Faculty of Humanities, Philosophy, 2021

- Description: Southern Africa is a region increasingly experiencing the detrimental effects of climate change and variability. The rural areas in particular face unprecedented climate change-induced challenges in relation to small-scale farmers being able to pursue household-based livelihoods, and these farmers seek ways of adapting to climate change and variability in doing so. Some rural communities exist along territorial borders and their attempts at adapting to climate change entails cross-border networks and activities. In this context, this thesis examines small-scale farmer adaptation to climate change and variability in the small village of Ezondweni in Malawi near the Zambian border. Analytically, the study draws upon the Sustainable Livelihoods Framework as well as social network theory and the theory of reflexive agency put forward by Margaret Archer. A qualitative research design entailed informal interviews with a small number of Ezondweni villagers, focusing on their perceptions of climate change and their practices of climate change adaptation. The study demonstrates the diverse activities pursued by villagers, both within Malawi and beyond, in seeking to maintain household-based livelihoods, as well as the significance of mutually-supportive social networks which facilitate these livelihood processes. , Thesis (MSocSci) -- Faculty of Humanities, Social Science, 2021

- Description: This study sets out to explore the meaning, extent, and impact of the generational divide, between so-called Baby Boomers and their Millennial offspring, on the way news is accessed, consumed, shared, and produced in five purposively selected households in the Johannesburg area. Aside from these widely-used generational identifiers, Baby Boomers and Millennials are also commonly referred to as Digital Immigrants and Digital Natives, respectively. However, in a world where smartphones have become commonplace, and internet connectivity via fixed broadband and mobile data is ubiquitous, it can be argued that digital technologies now serve as a link, or perhaps even a bridge, between younger and older generations living in the same household. The study aims to put this proposition to the test, by interrogating the role of news as a conduit for storytelling and information-sharing in environments where each occupant will typically be using their own devices, with a wide variety of personally-curated news sources and platforms at their fingertips. This fragmentation or individualisation of access to news stands in sharp contrast to the communal traditions of the pre-Internet era, during which families would gather around the TV set to watch the evening newscast, or share sections of the Sunday newspaper according to their age and interest. This research, which seeks to address a gap in the literature of research into intra-generational news consumption in family households in the digital era, identifies points of intersection as well as diversion in media usage habits. An example of the former is the prevalence of WhatsApp as a centralised "meeting-point" for the sharing of useful, hyper-localised information within the family group, and beyond that, as a cross-generational news and discussion platform in its own right. On the opposite end of the spectrum, the study explores strict and seemingly counterintuitive divides between the generations, with some Millennial respondents rejecting social media platforms as "pointless and invasive, and some Baby Boomer parents embracing the platforms as forums for free expression and networking. In line with the key research question, which seeks to identify and analyse news usage and consumption across the generations in a selection of family households, the study considers the ways in which families in the digital era are creating a culture of shared interests and the active sharing of news, breaching the boundaries of their private spaces in a microcosm of the Habermasian public sphere of discourse and opinion. , Thesis (MA) -- Faculty of Humanities, Journalism and Media Studies, 2021

However, in a world where smartphones have become commonplace, and internet connectivity via fixed broadband and mobile data is ubiquitous, it can be argued that digital technologies now serve as a link, or perhaps even a bridge, between younger and older generations living in the same household. The study aims to put this proposition to the test, by interrogating the role of news as a conduit for storytelling and information-sharing in environments where each occupant will typically be using their own devices, with a wide variety of personally-curated news sources and platforms at their fingertips. This fragmentation or individualisation of access to news stands in sharp contrast to the communal traditions of the pre-Internet era, during which families would gather around the TV set to watch the evening newscast, or share sections of the Sunday newspaper according to their age and interest. This research, which seeks to address a gap in the literature of research into intra-generational news consumption in family households in the digital era, identifies points of intersection as well as diversion in media usage habits. An example of the former is the prevalence of WhatsApp as a centralised "meeting-point" for the sharing of useful, hyper-localised information within the family group, and beyond that, as a cross-generational news and discussion platform in its own right. On the opposite end of the spectrum, the study explores strict and seemingly counterintuitive divides between the generations, with some Millennial respondents rejecting social media platforms as "pointless and invasive, and some Baby Boomer parents embracing the platforms as forums for free expression and networking. In line with the key research question, which seeks to identify and analyse news usage and consumption across the generations in a selection of family households, the study considers the ways in which families in the digital era are creating a culture of shared interests and the active sharing of news, breaching the boundaries of their private spaces in a microcosm of the Habermasian public sphere of discourse and opinion. , Thesis (MA) -- Faculty of Humanities, Journalism and Media Studies, 2021

- Description: The aim of the dissertation was to investigate whether the adoption of a national system of innovation has helped facilitate development in South Africa from a comparative BRICS perspective. South Africa has an expanding focus on science and technology, as per the Science and Technology White Paper (1996). There appeared to be innovation that had left out much of the citizenry. There continued to be poverty, inequality, and joblessness. The study aimed to understand how the NSI approach could be used to foster inclusive and transformative development. The study used a mixed-methods approach. The qualitative aspect of the research focused on an innovation and public policy study which assessed the various policies and initiatives implemented in each of the BRICS countries to drive innovation and foster development. The qualitative aspect of the study found that the innovation paradigm required governments to adopt a more holistic approach to public policy design and analysis. The quantitative aspect of the research focused on a trend, correlation, and regression analysis. The trend analysis revealed that China and Brazil increased their allocation of resources towards R&D compared to the other countries. Brazil is regarded as a social investment state, while China is a developmental state: this means the state plays an extraordinarily strong coordinative and financing role in the NSI. On the other hand, the correlation matrix for South Africa revealed a statistically significant positive linear association between various NSI indicators and human development. This suggested that the innovation benefits are trickling down to the general citizenry. In essence the study articulated key elements of the understanding of current and potential impacts of technological change in productivity and growth, employment and inequality that can be used for policy making. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economic History, 2022

- Description: Literature has suggested that Malawians are keen to participate. Malawian’s willingness to participate is evident as the country has recorded high voter turnouts during the elections in recent decades. However, literature also suggests that there is minimal citizen engagement in between elections. Elsewhere, Information and Communication Technologies (ICTs) have been used to enhance citizen engagement, but ICT led citizen engagement is still an emerging field and yet to be explored as an area of research particularly in Malawi. We thus sought to explore if the use of ICTs could improve citizen engagement with councils, councilors, and utility companies that provide water and electricity in Malawi. We developed and deployed an ICT platform called Mzinda which means My location in Malawi’s populous Chichewa language. The platform provided various channels for citizens and duty bearers to engage via SMS, USSD, web and a mobile application. We sought to understand the factors that influence citizen’s behavior intention to use an ICT platform to engage. We applied the modified UTAUT model by including Attitude and Self Efficacy social constructs that have among others been cited as limitations of the UTAUT model. We conducted factor loadings of six social constructs of the modified UTAUT model to validate content and reexamine the model in the context of citizen engagement using ICTs in Malawi. We found that, Attitude and Self Efficacy were not significant determinants of the Behaviour Intention for citizens to use the ICT platform. However, 75% of the Behaviour Intention was influenced by Perfomance Expectancy and Effort Expectancy as moderated by age and gender. Empirical evidence showed that responsiveness and actionability of councils and councillors had improved. We also learned that citizens believed that service delivery had improved and that they had more influence over councils, councillors, and the utility companies because of using the ICT platform. We conclude by noting that improvements in service delivery; enhanced responsiveness and actionability of councils, councillors and the utility companies were not necessarily as a result of the ICT platform alone; but a combination of ICTs and non-technology mechanisms of engaging the stakeholders through community campaigns, radio programs, print media engagement, community meetings and debates among others. It is evident that ICTs are not the panacea of all citizen engagement problems. This research can be useful to researchers and practitioners in the technology and citizen engagement domains. , Thesis (MSc) -- Faculty of Science, Department of Computer Science, 2021

- Description: This case study explored how schools and teachers interpret and implement the Language in Education Policy for their classroom practices. Scholars like Alexander and Block (2012) note that the South African Language in Education Policy (LiEP) is one of the advanced policies globally. Other scholars like Perry (2015) and Ngcobo (2015) state that the policy in South Africa has failed when it comes to implementation. It is against this background that the research explored how schools and teachers interpret and implement the Language in Education Policy for their classroom practice in three primary schools in Kuruman, Northern Cape. The research methodology was qualitative and it used a case study approach. The study is informed and framed by the Language Policy framework and the CDA (Critical Discourse Analysis). The research sites were three Grade 4 classes and the participants were three teachers, three principals and three SGB Chairpersons from three different schools (one school in deep rural, another in semi-urban and the third in urban) in Kuruman. This case study, located in the interpretive paradigm, employed individual semi-structured interviews, non-participant classroom observations, document analyses and field notes for data collection. The study revealed that teachers are not versed in LiEP and their classroom practice is therefore not based on policy but on their own perceptions. Classroom practices were incongruent with what the Language in Education Policy requires. Even other documents which support the Language in Education Policy like the school language policies, were not used as guiding documents for classroom practice. Lastly, this study revealed that, despite a plethora of literature on how practice engages and disengages with Language in Education Policy (LiEP), the deconstruction of colonial and apartheid education is still a challenge especially in language use, perceptions of mother tongue instruction and the hegemony of English. One of the recommendations of this study is that teachers must be taught to use Languages of Learning and teaching required in their areas and they should also be given continuous professional development courses on policies so as to improve their practice. Language Policy Units should be set up within the provincial and district Departments of Education that would support the implementation of LiEP. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: This dissertation investigates the semantics of each tense and aspect in Xhosa. Since tense and aspect perform important pragmatic functions, the analysis takes into account the correlation between the verb and the wider discourse in which it is embedded. Tense reflects the temporal relation between the time of the utterance (speech time) and an interval the speaker makes the assertion about (reference time). The Remote Past and the Remote Future tenses differ from their Recent/Immediate counterparts in that they denote events which occurred in a significantly different situation than the speech time and/or events in the surrounding discourse. Aspect does not only indicate the relation between the time occupied by the real world event and the reference time chosen by the speaker. The Perfective aspect represents an event as a unique change-of-state that pertains to a single point on the timeline which at the same time functions as the reference time. By contrast, for the Imperfective aspect temporally links the event to a contextually provided reference time, e.g. the utterance time, a time adverbial, a period of time previously introduced in the preceding discourse, or the interlocutors’ shared experience. At the pragmatic level, the Perfective aspect tends to introduce an event’s resulting state into the discourse, whereas the Imperfective aspect tends to rule it out. Like the Imperfective aspect, the Anterior and the Prospective aspects assert an event’s occurrence from a contextually defined reference time. They refer to the consequent and the preparatory states of an event, respectively. On the pragmatic level, the Anterior aspect may also indicate that the truth-conditionality of the event’s resulting state is contradicted in the immediate discourse. This study shows that tense and aspect temporally represent different means of temporally assigning an event to a particular portion of the timeline. I further argue that aspect indicates whether the reference time is provided in the context (Imperfective, Anterior, Prospective) or whether it is introduced by the verb itself (Perfective). Furthermore, this study shows that aspect exhibits a pragmatic function by laying focus on different parts of the event that are relevant in the upcoming discourse. , Thesis (PhD) -- Faculty of Humanities, Linguistics and Applied Languages Studies, 2021

- Description: Gleditsia triacanthos L. (Fabaceae) (honey locust) is a fast-growing, deciduous tree indigenous to the United States of America. Introduced around the world as an ornamental tree, it has become invasive in a number of countries. Where it is invasive, G. triacanthos competes and replaces indigenous species; it creates dense stands along watercourses, posing a significant environmental threat. In South Africa, G. triacanthos is regarded as one of the country’s fastest spreading weeds. Gleditsia triacanthos produces numerous seeds contained in large hanging pods. Once dislodged from the pods, the seeds are dispersed by birds and mammals, including livestock, which eat the pods. It has been suggested that the seeds should be the target for biological control programme. Some invasive alien plant species are characterised by their ability to spread and establish in new ecosystems because they tolerate a wide range of environmental conditions. In order to predict areas of likely invasion, species distribution models (SDMs) are used to identify areas climatically suitable for their invasion, so enabling better targeted control of the plant species. Gleditsia triacanthos adapts to a wide range of climates and soil types, and tolerates salinity, drought and frost. Currently primarily restricted to the Grassland Biome of South Africa, G. triacanthos has doubled its distribution area in the past 15 years, and it is not known how far the species will spread. In this study we used two different modelling programmes, CLIMEX and MaxEnt, to predict areas where G. triacanthos could find favourable growing conditions; both SDMs showed that most of the country is suitable for G. triacanthos and that it will probably continue to spread, if left unmanaged, into new bioregions, such as the Karoo. In South Africa, the Asian seed-feeding bruchid, Megabruchidius tonkineus (Pic, 1914) (Coleoptera: Chrysomelidae: Bruchinae) has been recorded in the plant’s seed pods and has been considered as a biological control agent. The insect was not released as part of a formal biological control programme and neither host-specificity nor impact studies were conducted on the species prior to its discovery. In 2017 a decision was made to re-consider its status as a Abstract biological control agent until further details of its biology, host specificity, and impact on the seeds of G. triacanthos in South Africa were available. This study shows that Megabruchidius tonkineus has established across the entire G. triacanthos population in South Africa damaging approximately 9% of seeds. Laboratory studies show that, Megabruchidius tonkineus completes its larval development in the seeds of G. triacanthos in about 66.80 ± 0.6880 SE days before eclosing. In addition, the adult females oviposit on the following Fabaceae species: Arachis hypogaea, Albizia, julibrissin, Cicer arietinum, Pisum sativum, Dipogon lignosus, Peltophorum africanum, Podalyria buxifolia Senegalia burkei, Umtiza listerina and Vachellia sieberiana. However, larval development was limited to G. triacanthos. It is concluded that the seed-feeding beetle is not a threat to native Fabaceae species in South Africa, however, it does not damage enough G. triacanthos seeds to be considered a valuable biological control agent at this stage, and additional seed-feeding biological control agents should be considered to reduce the number of G. triacanthos seeds entering the environment. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2021
