- Description: This study describes three internationally recognised sopranos and their presentations of character psychology on stage, during their performances of the famous “mad scene” from Gaetano Donizetti’s opera Lucia di Lammermoor. These sopranos are Joan Sutherland, Mariella Devia, and Lisette Oropesa. I use Margaret Kartomi’s (2014) model of performativity to interpret the “madness” depicted by the three selected sopranos, as based on my interpretations of commercially released audio-visual recordings of their performances in the role of Lucia. Through analysing these performances with the help of Kartomi’s performativity model (which focuses on persona, emotion-and intersubjectivity, and reception), my research determines – with speculative interpretation, and within the reasonable limits of standard psychiatric frameworks – which mental illnesses the sopranos can be understood to have portrayed in their interpretations of the role of Lucia. The study’s goal is not to make an accurate mental health diagnosis of someone’s portrayal of a fictional character. (Considering the fact that one cannot make accurate mental health diagnoses for people who do not exist.) Rather, my focus is to discover which dramatic and possibly musical characteristics are utilised to perform this fictional character and give expressive content to her “madness”. The concept of “madness” and its psychological characterisation during performance thus becomes the framework from which to interpret and understand vocal and acting techniques related to opera in general and to bel canto more specifically. My research findings are that the three performers use facial expressions, different aspects of using the voice through bel canto singing, and body movements as a way of expression. Bel canto characteristics include coloratura embellishments, fioritura, melismas, messa di voce, squillo and chiaroscuro. The sopranos also show musical and dramatic elements in how they respond to the flute or glass harmonica during the ‘Mad Scene’ – which counts as the personae expressed by the performers. These personae are further applied in the emotional and intersubjectivity and the reception aspects of Kartomi’s performativity model. In the emotional and intersubjectivity aspect, the chorus and other characters singing on stage are read as emphasising the reaction of society on the mentally dysfunctional behaviour enacted by the sopranos. In the reception aspect, reviewers are used to filling in for audience members. I read their reactions as contributing factors in forming an understanding of the interpretations of the “mad scene” performed by the three sopranos. My reading of the three interpretations of the “mad scene” goes further by subjectively interpreting how these sopranos approximate different states of mental collapse. These readings include approximations of psychosis such as mania, dissociative personality disorder, and paranoid schizophrenic behaviour. Always, though, these mental health behaviours are identified as approximations to better understand vocal and acting techniques. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2023

- Description: The use of network telescopes to collect unsolicited network traffic by monitoring unallocated address space has been in existence for over two decades. Past research has shown that there is a lot of activity happening in this unallocated space that needs monitoring as it carries threat intelligence data that has proven to be very useful in the security field. Prior to the emergence of the Internet of Things (IoT), commercialisation of IP addresses and widespread of mobile devices, there was a large pool of IPv4 addresses and thus reserving IPv4 addresses to be used for monitoring unsolicited activities going in the unallocated space was not a problem. Now, preservation of such IPv4 addresses just for monitoring is increasingly difficult as there is not enough free addresses in the IPv4 address space to be used for just monitoring. This is the case because such monitoring is seen as a ’non-productive’ use of the IP addresses. This research addresses the problem brought forth by this IPv4 address space exhaustion in relation to Internet Background Radiation (IBR) monitoring. In order to address the research questions, this research developed four mathematical models: Absolute Mean Accuracy Percentage Score (AMAPS), Symmetric Absolute Mean Accuracy Percentage Score (SAMAPS), Standardised Mean Absolute Error (SMAE), and Standardised Mean Absolute Scaled Error (SMASE). These models are used to evaluate the research objectives and quantify the variations that exist between different samples. The sample sizes represent different lens sizes of the telescopes. The study has brought to light a time series plot that shows the expected proportion of unique source IP addresses collected over time. The study also imputed data using the smaller /24 IPv4 net-block subnets to regenerate the missing data points using bootstrapping to create confidence intervals (CI). The findings from the simulated data supports the findings computed from the models. The CI offers a boost to decision making. Through a series of experiments with monthly and quarterly datasets, the study proposed a 95% - 99% confidence level to be used. It was known that large network telescopes collect more threat intelligence data than small-sized network telescopes, however, no study, to the best of our knowledge, has ever quantified such a knowledge gap. With the findings from the study, small-sized network telescope users can now use their network telescopes with full knowledge of gap that exists in the data collected between different network telescopes. , Thesis (PhD) -- Faculty of Science, Computer Science, 2023

- Description: This study is situated in the context of the 2019 South African general election, which saw the lowest voter turnout since its first democratic election in 1994. Many have questioned the capabilities of the African National Congress (ANC) since they came into power in 1994, due to allegations of corruption, maladministration and poor leadership. The concerns about the party’s ability to manage the country’s various social issues have led to a drop in voter turnout. There was much discussion in the media about the lack of voter turnout amongst young people in South Africa. This topic became a trending topic on social media under the #iwanttovotebut hashtag. The sentiments expressed by South African Twitter users in the #iwanttovotebut memes are explored in this study. The analysis of the memes draws on the works of Kress and van Leeuwen’s (1996; 2006) visual social semiotics, Fairclough’s (1989) approach to Critical discourse analysis (CDA), and Thompson’s operation of ideologies. VSS allows for the description of the various semiotic resources that memers use to construct their meaning from multimodal texts. The tools provided by CDA go beyond the description of VSS and develop a more detailed analysis of how the memers construct their discourses of democracy/governance. Thompson’s (1991) approach to understanding how ideology operates in language enables the deepening of the understanding of the dominant and naturalised notions of democracy/governance. The findings indicate that memers have a limited understanding of democracy. They also have a limited understanding of how political parties operate and their responsibilities in the form of government and various agencies. In addition, it is not surprising that young people are not voting in the 2019 general election. This is a phenomenon that the media has characterized as “apathy.” However, this research indicates that it would be more accurate to describe it as “disillusionment.” , Thesis (MA) -- Faculty of Humanities, School of Journalism and Media Studies, 2022

- Description: The study critically examines and discusses language choice on twitter, a social media platform that has a vast number of people from different language groups. This diverse platform allows people to tweet, communicate, and share information online. There are tweets that trend and attract more engagement across different language groups. O jewa ke eng? which translates to ‘what’s bothering you?’ is one of those tweets, and it is communicated in Sesotho. (More discussion about the tweet in the introduction section that follows). According to Eisenstein, O’ Connor, Smith & Xing (2010) & Eisenstein (2016), “the popularity and ubiquity of social media allows access to a wide variety of spontaneous language enabling researchers to study language variation across space and time at large scale”, (Preotiuc-Pietro & Ungar, 2018: 1534). The introduction to the internet and socially mediated platforms such as Twitter and others has changed how information is produced and consumed. Social media allow people to communicate and engage in languages they are comfortable and familiar with. The study discusses language choice at three levels: language choice between isiXhosa verses English; isiXhosa verses other African languages and isiXhosa verses other varieties. The study is pursued with the overarching aim to investigate the possibility of African languages such as isiXhosa being used as dominant languages on social media. Thus, the study explores language use by isiXhosa speaking users on twitter that engaged with the tweet. Moreover, the study investigated why they choose to use one language over the other or multiple languages. To give a broader perspective on the study, language choice, language shift and language attitude are discussed and critically evaluated. Theoretically, the concept of code-switching and code-mixing is used when looking at bilingualism and multilingualism. It is imperative to look at multilingualism because the prevalent use of English is no longer a barrier to communication, social media platforms have created a space where African language users are able to engage in their native languages. Moreover, the study explores the use of standard and non-standard isiXhosa languages. There are varieties of languages such as tsotsitaal, slang and others, and these language varieties are not recognised as standard, used in educational settings and so on. In doing so, language attitude is used as the concept to investigate what propels isiXhosa users to or not to use these language varieties in the online communities. The study is explored with the aim to investigate whether social media either grows and preserves African languages online or these platforms are detrimental to these languages, as the language utilised on them is casual and vague, in terms of both spoken and written speech. , Olu phando luvavanya kwaye luxoxa nzulu ngokhetho lolwimi kuTwitter, ikhasi lonxibelelwano elinenani elikhulu labantu abavela kumaqela eelwimi ezahlukeneyo. Eli khasi labantu abohlukeneyo libavumela ukuba babhale, banxibelelane, kwaye babelane ngolwazi kwi-intanethi. Kukho ii-tweets (imibhalwana emifutshane) ezihamba phambili kwaye zitsala uthethathethwano phakathi kumaqela eelwimi ezahlukeneyo. O jewa ke eng? ethetha ukuthi, ‘ukhathazwa yintoni?’ yenye yezo tweets (yalo mibhalwana mifutshane), kwaye idluliselwe ngesiSuthu. (Ingxoxo engakumbi malunga ne-tweet (nombhalwana omfutshane) ifumaneka kwicandelo lentshayelelo elilandelayo). Ngokutsho kukaEisenstein, O’ Connor, Smith & Xing (2010) kunye noEisenstein (2016), “ukuduma kunye nobuninzi beendaba zoluntu kubangela ezo ndaba ukuba zinwenwele kwiindidi ezininzi zeelwimi nezivumela abaphandi ukuba bafunde ngokwahlukana kolwimi kwindawo kunye nexesha…”, (Preotiuc-Pietro & Ungar, 2008: 1534). Ulwaziso kwi-intanethi kunye namakhasi onxibelelwano oluntu afana ne-Twitter kunye namanye, luyitshintshile indlela ulwazi oluveliswa ngayo kunye nendlela olusetyenziswa ngayo. Amakhasi onxibelelwano oluntu avumela abantu ukuba banxibelelane kwaye bazibandakanye ngeelwimi abakhululekileyo ukuzisebenzisa nabaqhelene nazo Olu phando luxoxa ngokukhethwa kolwimi kumanqanaba amathathu: ukukhethwa kolwimi phakathi kwesiXhosa kunye nesiNgesi, isiXhosa kunye nezinye iilwimi ziseNtu, kwakunye nesiXhosa kunye nezinye iindidi zolwimi. Olu phando luqhutywa ngeyona njongo iphambili yokuphanda ukuba ngaba iilwimi zesiNtu ezifana nesiXhosa zingasetyenziswa njengeelwimi eziphambili kamakhasi onxibelelwano na. Kungoko, uphando luphonononga ukusetyenziswa kolwimi ngabo bantetho isisiXhosa kuTwitter abanxibelelana ne-tweet (nombhalo omfutshane). Olu phando, lukwaphanda ukuba kutheni bekhetha ukusebenzisa ulwimi oluthile kunolunye okanye iilwimi ezininzi. Ukunika umbono ngokuthe gabalala ngolu phando, ukukhethwa kolwimi, utshintsho lolwimi, kunye nesimo sengqondo solwimi ziyaxoxwa kwaye zihlolwa ngokunzulu. Ngokwethiyori, ingqikelelo yokutshintshatshintsha iilwimi kunye nokuxuba iilwimi (ukusebenzisa iilwimi ezahlukeneyo kumgca okanye umbhalo omnye) ziyasetyenziswa xa kujongwa ukusetyenziswa kweelwimi ezimbini kunye neelwimi ezininzi. Kunyanzelekile ukuba kujongwe ukusetyenziswa kweelwimi ezininzi kuba ukuxhaphaka kokusetyenziswa kwesiNgesi akusengomqobo kunxibelelwano, amakhasi onxibelelwano (amaqonga osasazo) oluntu avule indawo apho abasebenzisi beelwimi zesiNtu bakwaziyo ukuthetha ngeelwimi zabo zomthonyama. Ngaphezu koko, olu phando luphonononga ukusetyenziswa kweelwimi zesiXhosa ezisemgangathweni nezingekho mgangathweni. Kukho iintlobo ngeentlobo zeelwimi ezifana neTsotsitaal, ulwimi lwe-slang nezinye, kwaye ezi ntlobo zeelwimi aziqatshelwa njengeelwimi ezisemgangathweni, ezisetyenziswa kumajelo emfundo njalo njalo. Ngokwenza oko, isimo sengqondo solwimi sisetyenziswa njengengcamango yokuphanda ukuba yintoni eyenza abasebenzisi besiXhosa basebenzise okanye bangasebenzisi ezi ntlobo zeelwimi kwi-intanethi. Olu phononongo luphononongwa ngeenjongo zokuphanda apho amaqonga onxibelelwano akhula kwaye agcine khona iilwimi zesiNtu kwi-intanethi okanye lamaqonga onxibelelwano abubungozi kwezilwimi, njengoko ulwimi olusetyenziswa kula maqonga luqhelekile kwaye alucacanga, ngokwentetho ethethwayo nebhaliweyo. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2022

Ngokwethiyori, ingqikelelo yokutshintshatshintsha iilwimi kunye nokuxuba iilwimi (ukusebenzisa iilwimi ezahlukeneyo kumgca okanye umbhalo omnye) ziyasetyenziswa xa kujongwa ukusetyenziswa kweelwimi ezimbini kunye neelwimi ezininzi. Kunyanzelekile ukuba kujongwe ukusetyenziswa kweelwimi ezininzi kuba ukuxhaphaka kokusetyenziswa kwesiNgesi akusengomqobo kunxibelelwano, amakhasi onxibelelwano (amaqonga osasazo) oluntu avule indawo apho abasebenzisi beelwimi zesiNtu bakwaziyo ukuthetha ngeelwimi zabo zomthonyama. Ngaphezu koko, olu phando luphonononga ukusetyenziswa kweelwimi zesiXhosa ezisemgangathweni nezingekho mgangathweni. Kukho iintlobo ngeentlobo zeelwimi ezifana neTsotsitaal, ulwimi lwe-slang nezinye, kwaye ezi ntlobo zeelwimi aziqatshelwa njengeelwimi ezisemgangathweni, ezisetyenziswa kumajelo emfundo njalo njalo. Ngokwenza oko, isimo sengqondo solwimi sisetyenziswa njengengcamango yokuphanda ukuba yintoni eyenza abasebenzisi besiXhosa basebenzise okanye bangasebenzisi ezi ntlobo zeelwimi kwi-intanethi. Olu phononongo luphononongwa ngeenjongo zokuphanda apho amaqonga onxibelelwano akhula kwaye agcine khona iilwimi zesiNtu kwi-intanethi okanye lamaqonga onxibelelwano abubungozi kwezilwimi, njengoko ulwimi olusetyenziswa kula maqonga luqhelekile kwaye alucacanga, ngokwentetho ethethwayo nebhaliweyo. , Thesis (MA) -- Faculty of Humanities, School of Languages and Literatures, 2022

- Description: This dissertation explores the ways in which individuals embody cyborg realities through engaging with technological aids. It examines how these interactions have the potential to bring to light new ways of thinking about and experiencing daily distresses. Pertinent human technology interaction was observed through an overarching cyborg lens, embedded in posthumanist thought. The study began with a “human as cyborg” ontology that sought to impress upon readers the intimacy with which technology is entangled in our lives. It aimed to call to attention the use of the cyborg myth as it is concerned with “transgressed boundaries, potent fusions, and dangerous possibilities” (Haraway, 1985:7). The study followed a cyber ethnographic strategy, where cyber ethnography refers to a virtual research method that observes social and cultural phenomena that are mediated by online interactions. Data was collected over a period of eight months, beginning in December 2020 and ending in July 2021. It was collected through the following means: a short self-administered online questionnaire, computer mediated in-depth interviews, and group interviews. I also kept a journal on reflections of my own use of these supportive technologies. After analysing the results of in-depth interviews with nine primary participants and twenty-six online questionnaires, the following key themes were brought to light: Firstly, the tethered self, or cyborg self, engages in evolved acts of ‘care of the self’ mitigated through supportive technology use. Secondly, access to new technologies brings about new ways of performing the self. Thirdly, engagement with supportive technologies provides opportunity for aiding distress in the way of encouraging self-reflective and self-interrogation behaviours as seen in mobile health app use. This constant self-interrogation behaviour in turn develops a kind of technological dependency, characterized by escapism and evolved methods of self- soothing. Lastly, exploring the use of technology to aid distress revealed that technologies generate equal opportunities for improved well-being, as they do for a decreased sense of connectedness and security. The research demonstrates that supportive technology use is entangled in the fabric of our everyday lives. Through it we fashion our identities, alleviate distress, evade distress, and discover new causes of distress. , Thesis (MSocSci) -- Faculty of Humanities, Anthropology, 2022

- Description: The Fourth Industrial Revolution (4IR) is set to disrupt existing economic and social structures through the use of cyber-physical systems that result from a fusion of the digital, biological, and physical spheres. The fifth and current long wave of innovation is going through such a digital revolution in the ongoing deployment period which is being driven by the generalpurpose technologies of Artificial Intelligence and the Internet of Things, among other cyberphysical systems. The impact of mobile money in the access of financial services has shown how disruptive incremental innovations in mobile and digital technologies can be. The transformational power of mobile money in financial access is due to its use as an accessible financial tool that utilizes mobile devices to send and/or receive money over great distances. With the 4IR looming, this thesis determines the factors that enable and constrain the adoption of a disruptive technology amongst Sub-Saharan African small, micro, and medium enterprises (SMMEs). Therefore, due to its impact on financial inclusion and the formalization of SMMEs, mobile money is used as an indicator for the adoption of 4IR disruptive digital technologies. The adoption of mobile money was evaluated using secondary data from a survey conducted by Research ICT Africa, which surveyed 4408 SMMEs in nine African countries. The Diffusion of Innovations (DOI) model and the Unified Theory of Acceptance and Use of Technology (UTAUT) model were used to identify the factors enabling and constraining the adoption of a disruptive technology, in this case mobile money. Factors included gender, vocational training, business skills training, tertiary education, services, performance expectancy, social media, location, and nine African countries (Kenya, Mozambique, Ghana, Nigeria, Rwanda, South Africa, Tanzania, Uganda, and Senegal). The factors were grouped into owner characteristics, firm attributes and country attributes. SMME owners with business skills (49%) showed the highest level of adoption in terms of owner characteristics, Kenyan SMMEs (21%) had the highest adoption between the countries surveyed, and social media (62%) showed the highest adoption in terms of firm attributes followed by the formal variable (47%). In general, only 29% of SMMEs surveyed adopted mobile money. The study found that women SMME owners were more likely to be affected by business formality when adopting a disruptive technology compared to male owned SMMEs. This is because informality often exacerbates other barriers/challenges women face such as lower access to finance, lower ability to exercise property, business, and labour rights, and lower visibility. The results also demonstrate that vocational training is more important than general tertiary education for the ii adoption of a disruptive technology such as mobile money. Furthermore, when using social media as a tool for business advice SMME owners were more likely to adopt the disruptive technology. The study suggests that to encourage African SMMEs to adequately adopt disruptive technologies of the 4IR, more women owned SMMEs need to enter the formal economy, and vocational training targeted at business skills must be promoted amongst all SMME owners. Eastern African SMMEs were found to be more likely to adopt mobile money compared to other African regions. The finding demonstrates the need for more African countries (particularly outside of the Eastern African region) to encourage innovation by addressing the four enablers of mobile connectivity (i.e. infrastructure, affordability, consumer readiness, and mobile services) which will in effect lead to economic growth and development. The study shows that to address country/regional differences, in addition to building the required infrastructure in terms of mobile internet connectivity, countries should increase the local relevancy of disruptive technologies between SMMEs. To achieve this the study suggests increasing mobile social media penetration rates. This is because when social media is used as a tool for business advice SMME owners are more likely to adopt a disruptive technology (as is the case with mobile money) due to the social influence of social media. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2022

- Description: Various human rights bodies have suggested that Inadequate Menstrual Health Management (MHM) could contribute to violations of human rights or, at the very least, is connected to the fulfilment of human rights. Despite recognition of this, there has not been thorough analysis of whether inadequate MHM is a violation of human rights, particularly in political discussions on the philosophy of human rights. Using a liberal cosmopolitan framework, this thesis attempts to bridge this gap and, ultimately, to argue that inadequate MHM constitutes a violation of human rights. This assertion brings with it various complications due to the heavily contested nature of human rights, their correlative duties, and the requirements for a lack of fulfilment to be considered a violation. I address each complication in turn. I argue that the traditional approach to human rights violations fails to consider the various ways that human rights are violated in our contemporary, globalised world. I suggest that structural violations of human rights should not be ruled out, particularly when we consider severe poverty and its by-products. Ultimately, the question of inadequate MHM is concerned with the content of human rights. If inadequate MHM were a violation, it would be a violation of women’s socio-economic rights. However, both group rights and socio-economic rights are contested. This thesis therefore justifies these rights. Group-differentiated rights are argued to be necessary for substantive equality. This is particularly the case when we consider the various risks women face simply because they are women. Women therefore need special protections and provisions for their human rights to be fulfilled. Socio-economic rights are necessary for the well-being and dignity of individuals everywhere. We can justify them even if they are costly, vague, and demanding on states, as critics argue they are. Therefore, if we can accept socio-economic rights and women’s rights, we can argue that inadequate MHM is a structural violation of human rights. Thinking about inadequate MHM in this way means we can respond to it with a level of urgency. This has the potential to improve the well-being, development, and dignity of women. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2023

- Description: Despite international research confirming its importance, writing and related metalinguistic skills have often been neglected in comparison to reading in literacy research (Cunningham et al., 2001; Castles & Coltheart, 2004; Nag, 2007; Roman et al., 2009; Zhao et al., 2017). On a national level there are very few studies that have explored the writing aspect of literacy in South Africa, and none that has investigated orthographic knowledge in a Southern Bantu language, such as isiXhosa. In an attempt to address this gap, this thesis explores orthographic knowledge and its components in isiXhosa. In particular, it seeks to investigate the unique predictors of word specific and general orthographic knowledge as well as their role for reading and spelling in isiXhosa while controlling for phonological awareness (PA), rapid automatized naming (RAN), and letter-sound knowledge. Furthermore, the thesis attempts to situate its findings within the main premises of the self-teaching hypothesis and dual route approach to orthographic processing in order to contribute to linguistic theories of reading with cross-linguistic evidence (Jorm & Share, 1983; Share & Jorm, 1987; Share, 1995; Grainger & Ziegler, 2011). A quantitative cross-sectional study was conducted with 140 isiXhosa home language third grade learners in which word specific and general orthographic knowledge tasks were specifically designed. These tasks were administered along with oral reading fluency (ORF), spelling, PA, RAN, and letter-sound knowledge. The findings revealed that letter-sound knowledge and PA contributed the largest variance towards both word specific and general orthographic knowledge. Further, word specific orthographic knowledge and letter-sound knowledge were the only significant predictors of spelling. Similarly, both word specific and letter-sound knowledge were significant predictors of reading, along with RAN and general orthographic knowledge. Quantile linear regression analyses revealed that word specific orthographic knowledge was a robust predictor of spelling and letter-sound knowledge was a robust predictor of reading across ability levels confirming the importance for word specific orthographic knowledge for spelling and letter-sound knowledge for reading in isiXhosa. In relation to the two reading theories considered in this thesis, the findings reflect similarities between the assertions of the self-teaching hypothesis and current thesis with suggestions made for further inquiry. The dual route approach to orthographic processing provides insights into the potential processing of orthographic information while reading in isiXhosa. The findings of this study confirm the importance of orthographic knowledge for reading and spelling for languages with transparent orthographies such as isiXhosa. , Thesis (MA) -- Faculty of Humanities, Linguistics and Applied Language Studies, 2022

- Description: Despite the vast research on the negative impacts of invasive alien species on the environment, these species remain part of the rural communities due to their numerous livelihood uses. Thus, more research is required, focusing mainly on the impacts of invasive alien species on the livelihoods of rural communities. This study investigated the community perceptions of rosehip (Rosa rubiginosa) and its contribution to rural communities as an invasive alien species. Four community councils, Pitseng, Matlameng, Limamarela and Mphorosane in the Leribe District Lesotho, were assessed. The study followed the pragmatism paradigm. The contribution of rosehip to rural livelihoods was analysed by comparing income from rosehip with other income sources. The study used simple random sampling and snowball sampling to select a representative of 160 respondents. The primary data was collected using semi-structured questionnaires. Moreover, SPSS and Stata statistical package programs were used for statistical analyses. The results showed that rosehip's livelihood benefits, its negative impacts, the length of time it has been available in the area, and its abundance highly influence the social, economic and environmental perception of rural communities. Furthermore, the study revealed that although the income from rosehip is extremely low and available for only three months of the year, the income plays an important part to the poorer households who have no other income sources. The study found that the main reason for engagement in rosehip harvesting despite its challenging nature was unemployment. The study also revealed that rosehip is part of the risk-reducing strategy or income diversification. Some households used it to complement other sources of income, such as agricultural production. Rosehip trade, if well-controlled, has the potential to alleviate rural poverty by creating job opportunities, providing a source of household income, and acting as a safety net in the face of shocks such as limited job opportunities and food shortages. In conclusion, households’ perceptions of rosehip have proven that rosehip is a valuable resource that provides a supplementary income that contributes towards alleviating poverty in Lesotho’s rural communities. The study recommends the private sector to establish and manages small agro-processing industries focusing on products used daily. The study also encourages environmental education and indigenous knowledge among community members, which would include knowledge and recognition of invasive alien species and their potential benefits and threats. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economic History, 2022

Four community councils, Pitseng, Matlameng, Limamarela and Mphorosane in the Leribe District Lesotho, were assessed. The study followed the pragmatism paradigm. The contribution of rosehip to rural livelihoods was analysed by comparing income from rosehip with other income sources. The study used simple random sampling and snowball sampling to select a representative of 160 respondents. The primary data was collected using semi-structured questionnaires. Moreover, SPSS and Stata statistical package programs were used for statistical analyses. The results showed that rosehip's livelihood benefits, its negative impacts, the length of time it has been available in the area, and its abundance highly influence the social, economic and environmental perception of rural communities. Furthermore, the study revealed that although the income from rosehip is extremely low and available for only three months of the year, the income plays an important part to the poorer households who have no other income sources. The study found that the main reason for engagement in rosehip harvesting despite its challenging nature was unemployment. The study also revealed that rosehip is part of the risk-reducing strategy or income diversification. Some households used it to complement other sources of income, such as agricultural production. Rosehip trade, if well-controlled, has the potential to alleviate rural poverty by creating job opportunities, providing a source of household income, and acting as a safety net in the face of shocks such as limited job opportunities and food shortages. In conclusion, households’ perceptions of rosehip have proven that rosehip is a valuable resource that provides a supplementary income that contributes towards alleviating poverty in Lesotho’s rural communities. The study recommends the private sector to establish and manages small agro-processing industries focusing on products used daily. The study also encourages environmental education and indigenous knowledge among community members, which would include knowledge and recognition of invasive alien species and their potential benefits and threats. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economic History, 2022

- Description: There are several pests of phytosanitary concern in the citrus industry in South Africa. Orchard sanitation can play an important role in suppressing the populations of these pests, however there are little data on the efficacy of sanitation techniques. Therefore, the current study investigated the effect of fruit disposal techniques and burying depths on the eclosion of the most important pests of citrus in South Africa, false codling moth Thaumatotibia leucotreta Meyrick (Lepidoptera: Tortricidae), Mediterranean fruit fly or Medfly Ceratitis capitata Wiedemann (Diptera: Tephritidae), Natal fruit fly Ceratitis rosa Karsh (Diptera: Tephritidae), and Oriental fruit fly Bactrocera dorsalis Hendel (Diptera: Tephritidae). Abscised C. sinensis fruits were inoculated with larvae of T. leucotreta, and eggs of C. capitata, C. rosa, and B. dorsalis, before being disposed as pulped, or whole, and buried at different depths (0 cm, 5 cm, 25 cm, and 50 cm). Abundance and richness of predatory ants were monitored using pitfall traps to ascertain their effect on the mortality of the immature stages of these pests. Ceratitis capitata and C. rosa failed to eclose from the inoculated fruits disposed at different depths, however, T. leucotreta and B. dorsalis adults did eclosed. Significantly fewer B. dorsalis eclosed from fruits that were pulped in comparison to eclosion where the fruit were left whole (F (3, 16) = 11.45, P < 0.01). Furthermore, depth of burial had a significant effect on the number of eclosed adults of Drosophila sp (F (3, 112) = 3.43, P < 0.01). Burying fruits at 50 cm suppressed the eclosion of all the internal feeding pests tested. Twenty-seven thousand seventy-three individual ants (Hymenoptera: Formicidae) were sampled from the same plots as used above, with at least 47% and 53% sampled from plots where pulped and whole C. sinensis fruits were disposed of, respectively. The ants were identified to morphospecies which included Pheidole1, Pheidole2, Formicinae1, Formicinae2, Formicinae3, and Myrmicinae1. The disposal of the inoculated C. sinensis fruits either as pulped or whole and burying at different depths significantly suppressed and/or delayed the eclosion of either of the tested internal feeding pests of citrus. Although, predacious ants were sampled from the same treatment plots they did not affect the survival or eclosion of the tested pests, and this could be attributed to the application of the slow toxic ant bait. Therefore, based on the observed results B. dorsalis adults showed the ability to eclose from 50 cm depth where fruit was either disposed as pulped or whole, thus, citrus farmers are advised to use hammer mill that will finely crush sanitised fruit, and/or bury fruit beyond 50 cm depth to prevent the adult od this pest from eclosing. , Thesis (MSc) -- Faculty of Science, Zoology and Entomology, 2022

- Description: This study examines educational governance in schools for internally displaced learners in Puntland, Somalia. Many Somalis have been internally displaced from the south and central of Somalia and neighbouring regions because of armed insurgence, as well as climate and ecological disasters. Communities of internally displaced Somalis who have settled in the north-eastern region of Somalia, together with the Ministry of Education and nongovernmental organisations such as Relief International, have established schools for internally displaced learners. The study uses interviews with teachers, school principals and school committee members to examine their experiences of how schools are governed, specifically in terms of the bottom-up and top-down approaches to peacebuilding education. This research study is the first of its kind to examine the experiences of education actors in internally displaced person schools in Somalia. It provides crucial, new information on northern NGOs and how they shape the governance of knowledge and resources in Somali schools and how Somali education actors interpret and respond to these interventions. Drawing on education studies and international relations, it develops a transdisciplinary framing of peacebuilding education and specifically focuses on the top-down and bottom-up approaches to peacebuilding education provision. It weaves these two disciplinary perspectives together to help establish the implications of the security sector in education and broadly post-conflict reconstruction. The study finds that donors, international NGOs and government actors use a top-down approach to education, which may sit at odds with local needs and priorities. It finds that Somali knowledge and values are marginalised in the curriculum and teachers’ professional development and that the distribution of resources such as teacher salaries and school feeding programmes is fragmented, opaque and lacking in accountability. The study emphasises that the exclusion of local voices may further contribute to the causes underlying conflict. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2022

- Description: The relationship between economic growth and taxation is a complex and highly debated issue, this thesis investigates whether a significant relationship can be identified, and whether it is the level that truly matters for fiscal policies aimed at being growth enhancing. Further investigation examines this relationship, in addition to testing whether there is a threshold below which tax collection may be considered ‘growth-enhancing’, and above which is negative for economic growth, and if such a threshold exists, to identify the manner in which taxation negatively impacts economic growth. The study makes use of a panel data approach to autoregressive distributed lag modelling and a generalised least squares regression. The study focuses on a panel data sample for seven (7) countries within Sub-Saharan Africa (SSA) between 1997 – 2017. It found that total tax revenue held a positive and significant relationship with economic growth at the SSA level, whilst at the individual tax level; PAYE and property taxes were found to have a negative influence on growth, with no other fiscal variables significantly influencing growth in the long run in SSA test. Whereas, when analysing at the country-specific level it was found PAYE was only significantly influencing growth in South Africa, where the relationship was found to be negative. Corporate tax revealed a similar significant negative relationship in Swaziland and Cameroon. In addition, property taxes revealed a significant and negative relationship in South Africa, yet in Rwanda the influence was positive. Overall, the study found that there is significant relationship between economic growth and taxation in the SSA context. However, when analysing the countries in isolation, no such relationship was found. , Thesis (MEcon) -- Faculty of Commerce, Economics and Economic History, 2022

- Description: As Sapolsky (2015) notes, stress research has long been characterised by definitional debates that gave rise to a lack of agreement between theorists. An example of this definitional confusion can be seen in the area of Language Learning Anxiety, where there appears to be confusion in the literature over terms such as anxiety and stress. This study investigated the link between stress and language learning using wearable devices measuring heart rate variance, as a means of establishing the feasibility of using this new technology in stress research. The results indicate that the contextualised longitudinal data delivered by wearable devices mitigates against the current dominant paradigm in Language Learning Anxiety, which postulates a straight-line negative correlation between stress and learning. Instead, the inverted U stress relationship proposed by theorists such as Hebb (1955) seem to be a better fit for the data. The nature of the contextualised data generated in this study allowed for comparisons between participants’ stress readings in academic contexts, such as language and non-language classes, and their free time. The findings suggest that certain long-held assumptions about heightened stress in academic contexts may not hold true. While the findings of this study did not reach the levels of statistical significance, they constitute proof of concept that the type of contextualised data delivered by wearable devices may allow for a new type of stress research that incorporates contextualising longitudinal perspectives on participants’ stress levels. In this study the inclusion of contextualising data led to fundamentally different conclusions about the relationship between stress and language learning. The same may be true of many areas of stress research. The findings presented in this study have broader paradigm-altering implications not only for educational policy, but also for stress research in general. Perhaps equally important was that the type of data delivered by wearable devices was qualitatively different from that normally associated with quantitative studies. This presented challenges in data analysis in this study, but also opens intriguing possibilities regarding a means of reconciling the qualitative and quantitative split in research modalities. The use of wearable devices is not without issues, and some of the issues, ranging from practical considerations to ethical conundrums, are presented for the reader’s consideration and to inform future researchers regarding potential pitfalls. , Thesis (PhD) -- Faculty of Humanities, Psychology, 2022

- Description: Invasive alien cacti are prominent weeds that threaten indigenous biodiversity and have a negative impact on agricultural productivity in South Africa. These plants are problematic because they form dense thickets that reduce the carrying capacity of rangelands; restrict the movement of livestock and wildlife thus reducing access to shade and water sources; and are directly harmful to livestock, wildlife and people due to their sharp spines. Biological control is the most effective, affordable and environmentally friendly method to control invasive alien cacti and minimize their negative impacts. Cochineal insects (Dactylopius spp.: Dactylopiidae) and the gall-forming mealybug, Hypogeococcus sp. (Pseudococcidae) are used as biological control agents for cacti. The agents are however poor dispersers, so mass-rearing and augmentative releases are required in order to establish the agents at sites where they are needed. This study aimed to evaluate the mass-rearing and release efforts of cactus biological control in South Africa, quantify the impact of the biological control agents on cactus plant populations through long-term monitoring, and assess the benefits accrued due to the biological control agents through the perceptions of land-users. An assessment of the effectiveness of the release effort for cactus biological control agents was conducted by comparing where biological control agents have been released with the known distribution of the target weeds. Only 26% of the quarter degree squares that are known to be occupied by invasive alien cacti have had biological control agents released in them. This indicated that the mass-rearing and release efforts in South Africa are inadequate and should be increased, especially in areas where few releases have been made and many cacti are present, such as the Limpopo Province. The impact of the biological control agents on cactus plant populations was assessed by monitoring agent densities, target plant densities and target plant reproductive outputs before and after releases. Plant biomass and reproductive output were reduced by biological control agents for three of the target weeds that were assessed, while the duration of the study was too short to measure reductions for the fourth target weed. Benefits to land-users were then quantified through a questionnaire survey. Land-users perceived biological control as an effective management option, with 81% of the land-users reporting that there was less invasive alien cactus after releasing biological control agents on their land. Forty-nine percent of the land-users believed that the negative impacts of the cactus had been reduced and that they benefited more from their land since control was achieved. Since land-users were only interviewed within four years of the releases being conducted, it is expected that the percentage of land-users who gained benefits from biological control will increase in future. Ninety-seven percent of the land-users stated that the agents were safe and had not fed on any other plants or had any detrimental impacts. These perceptions indicated that land-users regarded biological control as a safe and effective method of controlling invasive alien cacti. This study confirms that biological control is an effective and safe way of controlling invasive alien Cactaceae. It is also the first to assess some of the benefits that land-users have accrued due to biological control of cactus weeds. It is however evident that a greater mass-rearing and release effort is required for South Africa to get the maximum benefits possible from the use of the biological control agents for cactus weeds that are available in the country. , Izityalo ze-cactus ezisuka kwamanye amazwe zilukhula olubalaseleyo, olwenza ingxaki kwintlobo ngeentlobo zezityalo nezilwanyana kwaye ezizityalo zinefuthe neziphumo ezingalunganga kwimveliso yezolimo eMzantsi Afrika. Ezi zizityalo ziyingxaki kuba zenza amatyholo ashinyeneyo athi anciphise umthamo wokusebenzisa umhlaba: zinqanda ukuhamba nogkukhululekileyo kwemfuyo nezilwanyana zasendle ngokwenza oko zingakwazi ukufikelela emthuzini xa kutshisa nakwimithombo yamanzi yokusela; zikwayiyo nengozi kwimfuyo, izilwanyana zasendle kunye nabantu ngenxa yamave abukhali afumaneka kwezizityalo. Ukulawula nokwehliza ubunzini nezinga lemigcipheko yezizityalo, kusetyenziswa indlela ekuthiwa yi-biological control. Lendlela yeyona ndlela isebenza ngokuphucukileyo, efikelelayo, nengenabungozi kokusingqongileyo. Izinambuzane ze- cochineal (i-Dactylopius spp.: Dactylopiidae) kunye ne-mealybug, i-Hypogeococcus sp. (Pseudococcidae) zisetyenziswe njengezixhobo ze-biological control ezinceda ukulawula ezizityalo ze-cactus zingafunekiyo. Ingxaki yazo ezizinambuzane zizixhobo ze-biological control zingentla kukuba azikwazi kuzisasaza ngokwazo ukuba zifikelele nakwizityalo ezikude ngoko ke ukukhuliswa nokukhutshwa ngobuninzi bazo kuyafuneka ukukhawulelana nalengxaki kunye nokwandisa amathuba wokuba zifikelele kuzozonke izityalo ze-cactus ekufuneka zizilawule. Olu phononongo lujolise ekuvavanyeni iinzame zokukhulisa ngobuninzi nokukhupha ezezinambuzane zizixhobo ze-bioloigical control zokulawula izityalo ze-cactus eMzantsi Afrika, ukujonga ubungakanani befuthe notshintsho elenziwa zezinambuzane zizixhobo ze-bioloigical control kwizityalo ze-cactus emva kwexesha elide lokuzijonga, kunye nokuvavanya inzuzo efunyenwe ngenxa yokulawula ezizityalo ze-cactus ngokwemibono yabasebenzisi bomhlaba. Uvavanyo lweenzame zokukhutshwa kwezixhobo zezixhobo zezinambuzane ze-bioloigical control kwizityalo ze-cactus lwenziwa ngokuthelekisa iindawo apho izixhobo zezinambuzane ze-biological control zikhutshwe khona kunye neendawo apho izityalo ze-cactus kwaziwayo ukuba ziyafumaneka khona. Yi-26% kuphela yesikwere sekota eyaziwayo ukuba kukhona izityalo ze-cactus nalapho kukhutshwe khona kwezinambuzane ezizixhobo ze-biological control. Oku kubonisa ukuba iinzame zokukhulisa nokukhutshwa kwezinambuzane ezizixhobo ze-biological control eMzantsi Afrika azanelanga kwaye kufuneka zandiswe, ngakumbi kwiindawo apho kukho ukhutsho olumbalwa olwenziweyo kunye nezityalo ze-cactus ezininzi ezifumaneka khona, njengePhondo laseLimpopo. Iimpembelelo yokukhutshwa kwezinambuzane ezizixhobo ze-biological control kwizityalo ze-cactus zavavanywa ngokujonga ubunizi bezinambuzane ezizixhobo ze-biological control, ukuxinana kwezityalo ze-cactus ekujoliswe kuzo kunye nemveliso yokuzala kwezityalo ze-cactus phambi nasemva kokuba kukhutshwe izinambuzane ezizixhobo ze-biological control. Ubungakanani bezityalo ze-cactus kunye nemveliso yokuzala ziye zacutheka emva kokukhutshwa kwezinambuzane ezizixhobo ze-biological control kwinzityalo ezintathu ze-cactus ebekujoliswe uvavanyo kuzo, ngelixa ixesha lophononongo lalifutshane kakhulu ukuvavanya unciphiso kwisityalo se-cactus sesine. Izibonelelo zabasebenzisi bomhlaba zaye zavavanywa kusetyenziswa uhlobo lwemibuzo. Abasebenzisi bomhlaba balubona ukusetyenziswa kwezinambuzane ezizixhobo ze-biological control njengendlela yolawulo olusebenzayo, yi81% yabasebenzisi bomhlaba echaze ukuba izityalo ze-cactus zecuthekile emva kokukhutshwa kwezinambuzane ezizixhobo ze-biological control emhlabeni wabo. Amashumi amane anesithoba eepesenti zabasebenzisi bomhlaba bakholelwa ukuba impembelelo ezingalunganga ze-cactus zincitshisiwe kwaye baxhamle kakhulu kumhlaba wabo okoko lwaphunyenzwa. Oludliwano-ndlebe belwenziwe kubasebenzisi bomhlaba kwisithuba seminyaka emine emva kokuba kukhutshwe izinambuzane ezizixhobo ze-biological control, kulindeleke ukuba ipesenti yabasebenzisi bomhlaba abathe bafumana izibonelelo kwi-biological control lonyuke kwixesha elizayo. Amashumi alithoba anesixhenxe ekhulwini abasebenzisi bomhlaba bachaze ukuba izinambuzane ezizixhobo ze-biological control zikhuselekile kwaye khange zidle kuzo naziphi na ezinye izityalo ezingezi eze-cactus ebekujoliswe kuzo okanye zineempembelelo eyingozi. Ezi mbono ziyabonisa ukuba abasebenzi bomhlaba bayithatha i-biological control njengendlela ekhuselekileyo nesebenzayo yokulawula izityalo ze-cactus zamanye amazwe. Olu phononongo luqinisekisa ukuba ulawulo olusebenzisa izinambuzane ezizixhobo ze-biological control yindlela esebenzayo nekhuselekileyo yokulawula iCactaceae yamanye amazwe. Ikwangolokuqala ukuvavanya ezinye zezibonelelo ezizuzwe ngabasebenzisi bomhlaba ngenxa ye-biological control yezityalo ze-cactus.

- Description: Invasive alien cacti are prominent weeds that threaten indigenous biodiversity and have a negative impact on agricultural productivity in South Africa. These plants are problematic because they form dense thickets that reduce the carrying capacity of rangelands; restrict the movement of livestock and wildlife thus reducing access to shade and water sources; and are directly harmful to livestock, wildlife and people due to their sharp spines. Biological control is the most effective, affordable and environmentally friendly method to control invasive alien cacti and minimize their negative impacts. Cochineal insects (Dactylopius spp.: Dactylopiidae) and the gall-forming mealybug, Hypogeococcus sp. (Pseudococcidae) are used as biological control agents for cacti. The agents are however poor dispersers, so mass-rearing and augmentative releases are required in order to establish the agents at sites where they are needed. This study aimed to evaluate the mass-rearing and release efforts of cactus biological control in South Africa, quantify the impact of the biological control agents on cactus plant populations through long-term monitoring, and assess the benefits accrued due to the biological control agents through the perceptions of land-users. An assessment of the effectiveness of the release effort for cactus biological control agents was conducted by comparing where biological control agents have been released with the known distribution of the target weeds. Only 26% of the quarter degree squares that are known to be occupied by invasive alien cacti have had biological control agents released in them. This indicated that the mass-rearing and release efforts in South Africa are inadequate and should be increased, especially in areas where few releases have been made and many cacti are present, such as the Limpopo Province. The impact of the biological control agents on cactus plant populations was assessed by monitoring agent densities, target plant densities and target plant reproductive outputs before and after releases. Plant biomass and reproductive output were reduced by biological control agents for three of the target weeds that were assessed, while the duration of the study was too short to measure reductions for the fourth target weed. Benefits to land-users were then quantified through a questionnaire survey. Land-users perceived biological control as an effective management option, with 81% of the land-users reporting that there was less invasive alien cactus after releasing biological control agents on their land. Forty-nine percent of the land-users believed that the negative impacts of the cactus had been reduced and that they benefited more from their land since control was achieved. Since land-users were only interviewed within four years of the releases being conducted, it is expected that the percentage of land-users who gained benefits from biological control will increase in future. Ninety-seven percent of the land-users stated that the agents were safe and had not fed on any other plants or had any detrimental impacts. These perceptions indicated that land-users regarded biological control as a safe and effective method of controlling invasive alien cacti. This study confirms that biological control is an effective and safe way of controlling invasive alien Cactaceae. It is also the first to assess some of the benefits that land-users have accrued due to biological control of cactus weeds. It is however evident that a greater mass-rearing and release effort is required for South Africa to get the maximum benefits possible from the use of the biological control agents for cactus weeds that are available in the country. , Izityalo ze-cactus ezisuka kwamanye amazwe zilukhula olubalaseleyo, olwenza ingxaki kwintlobo ngeentlobo zezityalo nezilwanyana kwaye ezizityalo zinefuthe neziphumo ezingalunganga kwimveliso yezolimo eMzantsi Afrika. Ezi zizityalo ziyingxaki kuba zenza amatyholo ashinyeneyo athi anciphise umthamo wokusebenzisa umhlaba: zinqanda ukuhamba nogkukhululekileyo kwemfuyo nezilwanyana zasendle ngokwenza oko zingakwazi ukufikelela emthuzini xa kutshisa nakwimithombo yamanzi yokusela; zikwayiyo nengozi kwimfuyo, izilwanyana zasendle kunye nabantu ngenxa yamave abukhali afumaneka kwezizityalo. Ukulawula nokwehliza ubunzini nezinga lemigcipheko yezizityalo, kusetyenziswa indlela ekuthiwa yi-biological control. Lendlela yeyona ndlela isebenza ngokuphucukileyo, efikelelayo, nengenabungozi kokusingqongileyo. Izinambuzane ze- cochineal (i-Dactylopius spp.: Dactylopiidae) kunye ne-mealybug, i-Hypogeococcus sp. (Pseudococcidae) zisetyenziswe njengezixhobo ze-biological control ezinceda ukulawula ezizityalo ze-cactus zingafunekiyo. Ingxaki yazo ezizinambuzane zizixhobo ze-biological control zingentla kukuba azikwazi kuzisasaza ngokwazo ukuba zifikelele nakwizityalo ezikude ngoko ke ukukhuliswa nokukhutshwa ngobuninzi bazo kuyafuneka ukukhawulelana nalengxaki kunye nokwandisa amathuba wokuba zifikelele kuzozonke izityalo ze-cactus ekufuneka zizilawule. Olu phononongo lujolise ekuvavanyeni iinzame zokukhulisa ngobuninzi nokukhupha ezezinambuzane zizixhobo ze-bioloigical control zokulawula izityalo ze-cactus eMzantsi Afrika, ukujonga ubungakanani befuthe notshintsho elenziwa zezinambuzane zizixhobo ze-bioloigical control kwizityalo ze-cactus emva kwexesha elide lokuzijonga, kunye nokuvavanya inzuzo efunyenwe ngenxa yokulawula ezizityalo ze-cactus ngokwemibono yabasebenzisi bomhlaba. Uvavanyo lweenzame zokukhutshwa kwezixhobo zezixhobo zezinambuzane ze-bioloigical control kwizityalo ze-cactus lwenziwa ngokuthelekisa iindawo apho izixhobo zezinambuzane ze-biological control zikhutshwe khona kunye neendawo apho izityalo ze-cactus kwaziwayo ukuba ziyafumaneka khona. Yi-26% kuphela yesikwere sekota eyaziwayo ukuba kukhona izityalo ze-cactus nalapho kukhutshwe khona kwezinambuzane ezizixhobo ze-biological control. Oku kubonisa ukuba iinzame zokukhulisa nokukhutshwa kwezinambuzane ezizixhobo ze-biological control eMzantsi Afrika azanelanga kwaye kufuneka zandiswe, ngakumbi kwiindawo apho kukho ukhutsho olumbalwa olwenziweyo kunye nezityalo ze-cactus ezininzi ezifumaneka khona, njengePhondo laseLimpopo. Iimpembelelo yokukhutshwa kwezinambuzane ezizixhobo ze-biological control kwizityalo ze-cactus zavavanywa ngokujonga ubunizi bezinambuzane ezizixhobo ze-biological control, ukuxinana kwezityalo ze-cactus ekujoliswe kuzo kunye nemveliso yokuzala kwezityalo ze-cactus phambi nasemva kokuba kukhutshwe izinambuzane ezizixhobo ze-biological control. Ubungakanani bezityalo ze-cactus kunye nemveliso yokuzala ziye zacutheka emva kokukhutshwa kwezinambuzane ezizixhobo ze-biological control kwinzityalo ezintathu ze-cactus ebekujoliswe uvavanyo kuzo, ngelixa ixesha lophononongo lalifutshane kakhulu ukuvavanya unciphiso kwisityalo se-cactus sesine. Izibonelelo zabasebenzisi bomhlaba zaye zavavanywa kusetyenziswa uhlobo lwemibuzo. Abasebenzisi bomhlaba balubona ukusetyenziswa kwezinambuzane ezizixhobo ze-biological control njengendlela yolawulo olusebenzayo, yi81% yabasebenzisi bomhlaba echaze ukuba izityalo ze-cactus zecuthekile emva kokukhutshwa kwezinambuzane ezizixhobo ze-biological control emhlabeni wabo. Amashumi amane anesithoba eepesenti zabasebenzisi bomhlaba bakholelwa ukuba impembelelo ezingalunganga ze-cactus zincitshisiwe kwaye baxhamle kakhulu kumhlaba wabo okoko lwaphunyenzwa. Oludliwano-ndlebe belwenziwe kubasebenzisi bomhlaba kwisithuba seminyaka emine emva kokuba kukhutshwe izinambuzane ezizixhobo ze-biological control, kulindeleke ukuba ipesenti yabasebenzisi bomhlaba abathe bafumana izibonelelo kwi-biological control lonyuke kwixesha elizayo. Amashumi alithoba anesixhenxe ekhulwini abasebenzisi bomhlaba bachaze ukuba izinambuzane ezizixhobo ze-biological control zikhuselekile kwaye khange zidle kuzo naziphi na ezinye izityalo ezingezi eze-cactus ebekujoliswe kuzo okanye zineempembelelo eyingozi. Ezi mbono ziyabonisa ukuba abasebenzi bomhlaba bayithatha i-biological control njengendlela ekhuselekileyo nesebenzayo yokulawula izityalo ze-cactus zamanye amazwe. Olu phononongo luqinisekisa ukuba ulawulo olusebenzisa izinambuzane ezizixhobo ze-biological control yindlela esebenzayo nekhuselekileyo yokulawula iCactaceae yamanye amazwe. Ikwangolokuqala ukuvavanya ezinye zezibonelelo ezizuzwe ngabasebenzisi bomhlaba ngenxa ye-biological control yezityalo ze-cactus.

- Description: The foundations of African feminisms are intertwined with the historical liberation of the African continent. Joice Mujuru’s five decades in Zimbabwean political parties are no different in showing the gendered nature of the fight against the intersectional oppressions of nation, race, class and gender. The research aimed to examine the political life of Joice Mujuru between 1973 and 2018 in various political roles and what this might mean for how women political leaders participate and make decisions as autonomous individuals within political parties in Zimbabwe. This study is a political biography of Joice Mujuru’s ideas and leadership in political parties in Zimbabwe since 1973, when she joined the Zimbabwe African National Union – Patriotic Front (ZANU-PF) as a guerilla of its military wing, the Zimbabwe African National Liberation Army (ZANLA). Mujuru was the only woman in the first ZANU-PF cabinet in 1980. She served the Zimbabwean government in different cabinet positions and became the first female vice-president in 2004, until her ousting in 2014. This study is based on an interview with Mujuru, and nine interviews with one Member of Parliament, two independent political party candidates, three academics, two CSO activists, the leader of LEAD political party in Zimbabwe and personal communication with a celebrated Zimbabwean writer. The study uses the concept of “patriarchal bargain” (Kandiyoti, 1988; Makhunga, 2016) and “femocracy” (Mama, 1995b) to show that Mujuru’s participation in political parties has been shaped by compromising and negotiating a complex web of patriarchal constraints for acceptance and respect. This study shows that wifehood and motherhood, the idea of musha mukadzi (‘woman as home’), stands out as a defining factor for Mujuru in her identity formation as a political party leader and how she views the roles of other women in Zimbabwean political parties and politics. I term this political identity maternal dignity, which is a collective set of ideas of maternal respect determining women’s participation in political parties. The study shows that Mujuru uses dominant ideas of maternal dignity as a tool of self-presentation and self-preservation to survive as a political leader. Mujuru’s expulsion from ZANU-PF and her subsequent leadership in other political parties demonstrates the ways in which maternal dignity limits women from shaping alternative ideas of leadership outside of respectable womanhood. Through a political biography of Mujuru, the study reaches the conclusion that post-independence Zimbabwe offers limited space for women’s leadership, whether those women have liberation history credentials or not. The strategy of maternal dignity that Mujuru has used to navigate her political career is a “patriarchal bargain” with limited possibilities for women’s meaningful participation, and the transformation of political parties and governance in Zimbabwe. , Thesis (MA) -- Faculty of Humanities, Political and International Studies, 2022

- Description: In light of changing health needs, health information systems are presented with a plethora of challenges. For instance, the rise of COVID-19 in the past year has led to the discourse on the strength of current health systems to support health needs and the readiness for the National Health Insurance in South Africa. In addition to operating in resource-constrained environments, the lack of synchrony between health information systems across health facilities led to the fragmentation of health information and diminished access to quality healthcare. This research, following the Design Science Research Methodology (DSRM) process, developed an IT governance conceptual framework (HISIG-CF), to inform the interoperability of health information systems. The HISIG-CF is developed from literature and qualitative data collected using an expert reviews method from practitioners in the healthcare sector who evaluated the constructs of the HISIG-CF. Thematic analysis and hermeneutics were used to analyse and interpret the data. The results revealed a need for more guidance to inform interoperability interventions and strengthen current health information systems. The contribution of this study is the HISIG-CF which is deemed relevant and potentially fit-for-purpose to improve health information systems interoperability within the healthcare sector in South Africa. , Thesis (MCom) -- Faculty of Commerce, Department of Information Systems, 2022

- Description: The study reviews the phenomenon of financial integration. During the late 1980s and 1990s, financial market integration around the world increased due to globalisation of investments and the need for higher returns and international risk diversification. The increase was accompanied by a significant increase in private capital flows into developing countries from developed countries. The main goal of the study is to examine bond market integration in the common monetary area The study therefore investigates the co-movement of government bond returns within the CMA using data from Eswatini, Namibia, and South Africa. The study attempts to find the short-run and long-run relationship of these government bond returns using the ARDL cointegration technique. The study uses daily data of 10-year government bond yields spanning from August 2014 to September 2019. The empirical results reveal that there exists a short-run and long-run relationship between South Africa and Eswatini. Between South Africa and Namibia, there only exist a short-run relationship. Just like the previously mentioned studies, the short-run relationship is a result of policy convergence. The lack of long-run relationship between South and Namibia was due to poor institutional developments and limited investment opportunities. In this case, policy measures (or reforms) and a review of the union are necessary to increase integration of these bond markets. , Thesis (MCom) -- Faculty of Commerce, Economics and Economic History, 2022
