- Description: Maize is Ethiopia’s dominant cereal crop regarding area coverage and production level. There are different varieties of maize in Ethiopia. Maize varieties are classified based on morphological features such as shape and size. Due to the nature of maize seed and its rotation variant, studies are still needed to identify Ethiopian maize seed varieties. With expert eyes, identification of maize seed varieties is difficult due to their similar morphological features and visual similarities. We proposed a hybrid feature-based maize variety identification model to solve this problem. For training and testing the model, images of each maize variety were collected from the adet agriculture and research center (AARC), Ethiopia. A multi-class support vector machine (MCSVM) classifier was employed on a hybrid of handcrafted (ie, gabor and histogram of oriented gradients) and convolutional neural network (CNN)-based feature selection techniques and achieved an overall classification accuracy of 99%.

- Description: The COVID-19 pandemic offered unprecedented obstacles to public health communication worldwide. Pandemic revealed disparities and significant gaps in access to public health information for those not proficient in English, potentially leading to the exclusion of indigenous language speakers and minority communities from issues of national interest, including vital COVID-19 updates. This chapter examines the case study of Rhodes University in the Eastern Cape, South Africa and explores the institution's language policies and practices during the pandemic. The institution grapples with linguistic diversity, where English is the primary language of teaching and administration. The study explores language, public health communication, and inclusion at Rhodes University. It seeks to find linguistic and cultural contestations during this time by evaluating the university's response to the pandemic through language. The study uses document analysis to understand how Rhodes University's language practices impacted public health communication during the pandemic.

- Description: In this chapter, a group of student-researchers and their lecturer discuss their findings relating to a podcasting intervention which took place in an Ethnomusicology thirdand fourth-year class at Rhodes University in Makhanda, Eastern Cape, South Africa. As part of a larger project, in which the class explored podcasting in general, they experimented with the medium in order to ascertain in what role it could be used as a learning and teaching aid in tertiary pedagogy. Audio recordings of the lecturer discussing journal articles relating to the module were sent to students. They listened to and used them in different scenarios, orchestrated to research their effectiveness in diverse learning and teaching situations. Using a qualitative case study research design methodology, the student researchers and their lecturer present these findings through a participatory lens. They analyse the podcasts’ efficacy and limitations from various perspectives through coding responses. Finally, they discuss future usage of the medium as a way to enhance students’ understanding of academic readings.

- Description: In 2017, Donald Trump signed the Protecting Life in Global Health Assistance (PLGHA), thereby reinstating the Global Gag Rule. The policy restricted all United States foreign funding from abortion-related activities. Little research reports the responses of recipients of this bilateral assistance. The study documents the South African government's responses to the PLGHA. We accessed Hansard parliamentary debates, interviewed four parliamentarians alongside one government official, and reviewed a USAID-funded initiative developed while the policy was in effect. We analysed the data using interpretive content analysis through a global social policy and gendered coloniality lens. Our research documents silence, ignorance, avoidance, and possible over-interpretation of the PLGHA within the South African government. The colonialist politics of global redistribution created the grounds for gendered regulation, resulting in a fundamental undermining of reproductive rights. Ironically, the solution – advocacy and parliamentarian briefing regarding sexual and reproductive issues – is generally led by civil society, the bodies weakened by the PLGHA.

- Description: The 21 cm transition from neutral Hydrogen promises to be the best observational probe of the Epoch of Reionisation (EoR). It has driven the construction of the new generation of lowfrequency radio interferometric arrays, including the Hydrogen Epoch of Reionization Array (HERA). The main difficulty in measuring the 21 cm signal is the presence of bright foregrounds that require very accurate interferometric calibration. However, the non-smooth instrumental response of the antenna as a result of mutual coupling complicates the calibration process by introducing non-smooth calibration errors. Additionally, incomplete sky models are typically used in calibration due to the limited depth and resolution of current source catalogues. Combined with the instrumental response, the use of incomplete sky models during calibration can result in non-smooth calibration errors. These, overall, impart spectral structure on smooth foregrounds, leading to foreground power leakage into the EoR window. In this thesis we explored the use of fringe rate filters (Parsons et al., 2016) as a mean to mitigate calibration errors resulting from the effects of mutual coupling and the use of an incomplete sky model during calibration. We found that the use of a simple notch filter mitigates calibration errors reducing the foreground power leakage into the EoR window by a factor of ∼ 102. Thyagarajan et al. (2018) proposed the use of closure phase quantities as a means to detect the 21 cm signal, which has the advantage of being independent (to first order) from calibration errors and, therefore, bypasses the need for accurate calibration. In this thesis, we explore the impact of primary beam patterns affected by mutual coupling on the closure phase. We found that primary beams affected by mutual coupling lead to a leakage of foreground power into the EoR window, which can be up to ∼ 104 times and is mainly caused by the unsmooth spectral structure primary of primary beam sidelobes affected by mutual coupling. This power leakage was confined to k < 0.3 pseudo h Mpc−1. Lastly, we also proposed and demonstrated an analysis technique that can be used to derive a flux scale correction in post-calibrated HERA data. We found that after applying flux scale correction to calibrated HERA data, the bandpass error reduces significantly, with an improvement of 6%. The derived flux scale correction was antenna-independent, and it can be applied to fix the overall visibility spectrum scale of H4C data post-calibration in a fashion similar to Jacobs et al. (2013). , Thesis (PhD) -- Faculty of Science, Physics and Electronics, 2024

- Description: Research on school-based sexuality education in South Africa, taught within Life Orientation (LO), has mainly focused on learners’ responses, how teachers approach the subject, and the curriculum content. Critiques have included heteronormative biases, an emphasis on danger, disease and damage, a reinforcement of gendered binaries, and the lack of pleasure or well-being discourses. In contrast, our research focused on the unexpected moments teachers experience, i.e., the ethical, emotional or psychological challenges they encounter in their interactions with learners.

Due to political influence certain languages are regarded as ‘languages of the state’and others are perceived to be ‘languages in the state’. Language practices during apartheid in South Africa were very influential in deciding the plight of indigenous African languages. During this period, indigenous African languages were subjected to suppression, wherein an exoglossic lan-guage policy remained intact. Mekoa (2020) explicates that language was used as an instrument of domination or subjugation during apart-heid and colonization. Mekoa (2020) further indicates that in South Afri-ca, indigenous African languages were denigrated and marginalized through legislative structures of the apartheid government.

- Description: This study presents a novel approach to understanding the economic freedom fighters (EFF) role in South African politics. The party has been called populist, fascist, and a threat to South Africa's democracy. This study was conducted through virtual ethnography research on the role of the EFF in South Africa's politics and presents the research findings here to understand if the EFF is merely populist, a threat to democracy, or encouraging citizens' political participation. The study's findings indicate that the EFF uses populist stances to attract supporters and voters to the party. But unlike the views of some commentators and scholars, the study presents different findings regarding the EFF's populist attitudes in the country's democracy. While some see such populist stances as a threat to democracy, the study views it as the party's advantage, among others, to encourage citizen political participation.

- Description: The use of protective netting is becoming an increasingly popular practice in the citrus industry in South Africa. However, data on its effects on biotic factors, particularly insect pests, are limited. This study focused on the effect nets have on key citrus pests in the Eastern Cape province. Orchards under nets and open orchards, of similar cultivars, ages and management practices, were monitored at several sites over two seasons for pest infestation and damage. Weekly monitoring was conducted for Thaumatotibia leucotreta infestation. Other pests were monitored either monthly or once a season.

- Description: The devastating impact of the COVID-19 virus is well-documented. The disease was less severe among young people than in the older population. The effect on adolescents was primarily due to government measures to curb the pandemic, including lockdowns that disrupted social, education, and health services and diverted resources away from sexual and reproductive health. Young people lost or had limited access to sexual and reproductive health services and comprehensive sexuality education. They experienced the loss of financial and emotional support and parental care because of sick adults and caregivers. Young persons also lost time with friends and in developmental tasks associated with adolescence, such as exploring intimate relationships and forming identities outside the home. Government-imposed lockdowns and isolation measures revealed how being home can be problematic for young people, despite the concept of ‘home’ suggesting safety, security, and nurturance. Of particular concern were sexual and gender-based violence in the home and the increase in teenage pregnancies. In this chapter, we engage with the notion of home and how all institutions with which the adolescent interacts, especially family and school, should be a ‘home’: A place of belonging and acceptance because adolescence is a critical time for the emergence of sexual identity.

- Description: The devastating impact of the COVID-19 virus is well-documented. The disease was less severe among young people than in the older population. The effect on adolescents was primarily due to government measures to curb the pandemic, including lockdowns that disrupted social, education, and health services and diverted resources away from sexual and reproductive health. Young people lost or had limited access to sexual and reproductive health services and comprehensive sexuality education. They experienced the loss of financial and emotional support and parental care because of sick adults and caregivers. Young persons also lost time with friends and in developmental tasks associated with adolescence, such as exploring intimate relationships and forming identities outside the home. Government-imposed lockdowns and isolation measures revealed how being home can be problematic for young people, despite the concept of ‘home’ suggesting safety, security, and nurturance. Of particular concern were sexual and gender-based violence in the home and the increase in teenage pregnancies. In this chapter, we engage with the notion of home and how all institutions with which the adolescent interacts, especially family and school, should be a ‘home’: A place of belonging and acceptance because adolescence is a critical time for the emergence of sexual identity.

- Description: Women who sell sex (WSS) are vulnerable to violence. We present a scoping review of the last decade of research on the prevalence and incidence of, factors associated with, and services regarding violence against WSS in Eastern and Southern African (ESA). A systematic search of various databases resulted in 20 papers being reviewed. Inclusion criteria, applied by the first two authors, were as follows: empirical papers, key research problem is violence against WSS, and conducted in ESA countries. The lifetime prevalence of violence revealed in the studies ranged from 21% to 82%. A pattern of generalized violence against WSS from paying clients, male partners, strangers, family members, friends/acquaintances, and the authorities emerged. Factors associated with violence included the context within which the sex work occurs, alcohol use, type of sex exchange interactions, and personal factors (low education, low income, marriage, youth, high client volume, time in sex work, forced sexual debut, and internalized sex work stigma). WSS seldom access services after violence. Evaluations of two programs, a woman-focused HIV intervention, and the Diagonal Interventions to Fast-Forward Reproductive Health project, showed improvements in gender-based violence services. Findings suggest that targeted programmes should be paired with improving general health services and focus on promoting collective agency among WSS.

- Description: Language is more than just a communication medium; it exists within interrelated social and political processes. Therefore, language never appears by itself; it always represents a system of social and political interests, reflecting the prevailing discursive and ideological strategies. The current chapter investigates the notion of “Zulu ethnolinguistic nationalism” as a language ideology in South African television. Having watched a series of television programs in South Africa and utilizing the corpus linguistic approach, the author asserts that there is a clear dominance of isiZulu in South African television. Ultimately, this dominance created a language ideology that privileges isiZulu over other indigenous languages on South African television.

- Description: Counselling psychology in South Africa has recently emerged from a tumultuous period, stemming from regulatory efforts in 2011, which negatively impacted on the profession’s status and viability. While the definition and scope of counselling psychology arguably demonstrate improvements in aligning with global practices, concerns persist surrounding the work opportunities and professional experiences of counselling psychologists, particularly those in the early stages of their careers. This study aimed to gain an in-depth understanding of the professional experiences of early career counselling psychologists in South Africa. The pool of participants were 10 early career counselling psychologists (females = 7, males = 3, period in service = 1–10 years). The participants completed semi-structured interviews on their early career professional experiences, as well as the meanings they attributed to these experiences. An interpretative phenomenological analysis of the data revealed three group experiential themes: (1) the complexity of finding and securing work; (2) navigating an array of personal, professional, and systemic challenges, and (3) self-acquiring support. The findings suggest that despite the unique and valuable skills and knowledge counselling psychologists possess, the participants struggled to successfully transition into the workforce, resulting in feelings of anxiety, frustration, and professional disillusionment. The findings indicate enhanced support is needed at various levels to address the needs and bolster the wellbeing, utilisation, and retention of counselling psychologists in their transition into the South African workforce.

- Description: Medication adherence is a patient's active and voluntary participation in following all the recommendations and instructions agreed upon with a health care provider such as a pharmacist. Adherence is a multidimensional phenomenon determined by the interplay of five factors: patient-related factors, socioeconomic factors, condition-related factors, health system-related factors, and therapy-related factors. Medication non-adherence is a problem in many countries, especially low to middle-income countries, including South Africa (SA). In low to middle-income countries, non-adherence is often worse due to insufficient health resources and inequities in access to health care. Medication adherence is a global problem and has raised the need for research and review. Many healthcare professionals, especially pharmacists, have an essential role in promoting medication adherence. This study described, explained and evaluated the policies in SA relating to the pharmacist's role in promoting medication adherence. Furthermore, it described medication adherence-related education at four universities in South Africa. The study was qualitative, and a two-phased approach was employed. In the first phase, a document analysis of the pharmacist’s role in supporting medication adherence was conducted as described in national policies and guidelines in SA. A total of 38 documents were analysed, including critical documents such as the South African Pharmacy Council Good Pharmacy Practice Manual and Associated SAPC rules (GPP) manual, National Drug Policy (NDP), Standard treatment guidelines (STGS) and Integrated Adherence Guidelines. The READ approach was used in conducting the document analysis and involved (1) preparing materials, (2) extracting data, (3) analysing data, and (4) distilling findings. The critical roles of pharmacists in medication adherence that were identified were in drug use, supply and management, dispensing, therapeutic drug monitoring, pharmacovigilance, pharmaceutical care, and special programmes like antimicrobial stewardship (AMS), multi-drug resistant tuberculosis (MDR-TB) care and antiretroviral treatment (ARV) and chronic conditions. In the second phase, in-depth interviews were conducted with lecturers to investigate and report on the inclusion of medication adherence and the teaching thereof in the curriculum of the Bachelor of Pharmacy Degree (BPharm) in pharmacy institutions in SA. Purposive sampling was used, and seven lecturers from four different institutions participated in the interviews. The interviews were conducted via Zoom® and were transcribed and analysed using thematic analysis. The teaching of medication adherence in the BPharm curriculum of the respective interviewed pharmacy institutions was explored. It was found that the topic of medication adherence was integrated into all subjects throughout the curriculum and not taught as a formal course. Although medication adherence is taught in many disciplines, it is predominantly in pharmacy practice in all institutions. The teaching methods identified included lectures, case studies, workshops, tutorials, practicals, readings, tasks, assignments and videos. The perceived effectiveness of the teaching methods was explored; also the time spent teaching medication adherence and the time efficiency. Student understanding, interest and engagement with the topic were explored and determined through their assessment performance and class attendance. In conclusion, from policies, the pharmacist's role concerning adherence is indirectly integrated into many other roles. It is often not distinguishable from that of other healthcare professionals and is often implied as part of a more generic role. Pharmacy students are educated on medication adherence and the skills and knowledge required to identify, monitor and support patient adherence to therapy. However, there is scope to increase the course content on medication adherence. There is a need to identify effective strategies for preparing pharmacists to assist patients in medication adherence. , Thesis (MPharm) -- Faculty of Pharmacy, 2023

- Description: This research investigation is based on continuous improvement changes arising from - and related to - ISO 9001 implementation at Sundays River Citrus Company (SRCC), which is one of the biggest packers, marketers, and exporters of citrus fruit in South Africa. The Board of SRCC adopted ISO 9001 to ensure organizational efficiency and sustainability while improving quality control, customer service, teamwork and leadership. However, research indicates not all organizations that have Implemented ISO 9001 realize the intended benefits. While no research was available on the citrus agriculture industry, research in the tourism industry indicates that not only did some companies not realize the expected benefits, but also incurred substantial investment costs. It is estimated that approximately thirty to ninety percent of change initiatives fail to meet their objectives, and research studies also indicate that middle managers play a critical role that can influence the outcomes of a change project. However, Balogun (2003) indicates that middle managers play a complex role and are exposed to role conflict, which can influence the outcomes of change initiatives. In this context, this research study aimed to investigate the role conflicts experienced by middle managers during the process of an ISO 9001 continuous improvement change. The study draws on role theory, applying it to their management of change. The following role conflict types were investigated: (1) intra-sender conflict, (2) inter-sender role conflict, (3) inter-role conflict, (4) role ambiguity and (5) role strain. The research approach is qualitative, and has adopted a post-positivist paradigm, utilizing a deductive qualitative method. The study adopted a case study approach. Data was gathered mainly from interviews and supported by organizational documents. Semi structured interviews were conducted with questions formulated through the use of the coding manual (See Appendix C) to ensure alignment of data collection with the research propositions derived from literature. A deductive thematic analysis method was used to analyze the interview data. The research findings confirmed that during continuous improvement change, as middle managers strived to satisfy the incompatible expectations of role senders (mainly senior and junior managers), they experienced the five role conflict types. The study findings also indicate that middle managers experience conflicts due to the incompatible expectations of other role senders such as quality and marketing departments. The findings suggest that middle managers are managing these conflicts, but notes that they do require some assistance and support from senior management. The study concludes with managerial and research recommendations. , Thesis (MBA) -- Faculty of Commerce, Rhodes Business School, 2023
