- Description: Licence plate recognition has many practical applications for security and surveillance. This paper presents a robust licence plate detection system that uses string-matching algorithms to identify a vehicle in data. Object detection models have had limited application in the character recognition domain. The system utilises the YOLO object detection model to perform character recognition to ensure more accurate character predictions. The model incorporates super-resolution techniques to enhance the quality of licence plate images to increase character recognition accuracy. The proposed system can accurately detect license plates in diverse conditions and can handle license plates with varying fonts and backgrounds. The system's effectiveness is demonstrated through experimentation on components of the system, showing promising license plate detection and character recognition accuracy. The overall system works with all the components to track vehicles by matching a target string with detected licence plates in a scene. The system has potential applications in law enforcement, traffic management, and parking systems and can significantly advance surveillance and security through automation.

- Description: This paper reports on recent successful work aimed at preventing crop loss and failure before visible symptoms are present. Food security is critical, especially after the COVID-19 pandemic. Detecting early-stage plant stresses in agriculture is essential in minimizing crop damage and maximizing yield. Identification of both the stress type and cause is a non-trivial multitask classification problem. However, the application of spectroscopy to early plant diseases and stress detection has become viable with recent advancements in technology. Suitable frequencies of the electromagnetic spectrum and machine learning algorithms were thus first investigated. This guided data collection in two sessions by capturing standard visible images in contrast with images from multiple spectra (VIS-IR). These images consisted of six plant species that were carefully monitored from healthy to dehydrated stages. Promising results were achieved using VIS-IR compared to standard visible images on three deep learning architectures. Statistically, significant accuracy improvements were shown for VIS-IR for early dehydration detection, where ResNet-44 modelling of VIS-IR input yielded 92.5% accuracy compared to 77.5% on visible input on general plant species. Moreover, ResNet-44 achieved good species separation.

- Description: Real time control over sound source positioning and movement is a primary advantage of object-based sound systems over channel-based systems. This paper describes a controller, processing engine, and associated library that enhances this object control. Apart from graphic spatialization control, the controller allows, for each object, the selection of its rendering algorithm, distance-based level, high frequency attenuation, reverb parameters and speaker isolation or locking. OSC control within the controller enables further control options.

- Description: The southern and eastern parts of the African Fynbos region favour the production of honeybush tea. Honeybush biomass and extracts are used to prepare a beverage both locally and internationally, mainly as herbal tea with health benefits. Honeybush tea is mostly grown organically requiring natural control measures for pests and diseases. The leafhopper, Molopopterus sp., is one of the most important pests of cultivated honeybush in South Africa, as its feeding compromises the quality and quantity of the yield through leaf discolouration and reduction of the photosynthetic area. Local entomopathogenic fungi (EPF) can provide a pool of potential biocontrol agents for this pest. Therefore, a total of 98 soil samples were collected from organically grown honeybush fields and vegetation surrounding the honeybush fields in the Western Cape province of South Africa. Entomopathogenic fungi were isolated using the insect bait method and were characterised using molecular techniques. Twenty fungal isolates of Metarhizium anisopliae and Fusarium oxysporum were recovered from soil samples, of which 70% were from honeybush fields and 30% were from surrounding vegetation.

- Description: Mussel beds form important intertidal matrices that provide thermal buffering to associated invertebrate communities, especially under stressful environmental conditions. Mussel shells are often colonized by photoautotrophic euendoliths, which have indirect conditional beneficial thermoregulatory effects on both solitary and aggregated mussels by increasing the albedo of the shell. We investigated whether euendolithic infestation of artificial mussel beds (Perna perna) influences the body temperatures of four associated mollusc species during simulated periods of emersion, using shell temperature obtained via non-invasive infrared thermography as a proxy.

- Description: Megamelus scutellaris Berg (Hemiptera: Delphacidae) is the most recent of nine biological control agents developed to manage invasive water hyacinth, Pontederia (= Eichhornia) crassipes Mart.(Pontederiaceae), in South Africa. More than a million M. scutellaris have been mass-reared and released since the first introduction of the agent into South Africa in 2013, successfully establishing overwintering populations at 32 sites in seven of the nine provinces. Establishment has also been recorded at seven of these sites through natural dispersal from sites where they had established. Inundative releases, where large numbers of M. scutellaris are released regularly, have resulted in excellent establishment, and caused a significant reduction in water hyacinth cover in areas where, historically, biological control seemed unlikely due to excessive eutrophication. Although M. scutellaris has established well throughout South Africa through classical biological control methods, this study also showed that inundative releases of biological control agents over multiple seasons results in the most effective control of the weed, especially at cool temperate and eutrophic sites.

- Description: In this work, we have described the synthesis of phthalocyanine complexes Zn(II) tetrakis 4-(5-formylpyridin-2-yl)oxy) phthalocyanine (2), Zn(II) tetrakis-1 butyl 4-(2-(6- (tetra-phenoxy)pyridin-3-yl) vinyl)pyridin-1-ium phthalocyanine (3) and Zn(II) tetrakis 1 butyl 5-(2-(1-butylpyridin-1-ium-4-yl)vinyl)-2-(tetra-phenoxy)pyridin-1-ium phthalocyanine (4). The effect of a varying number of charges when the Pc complexes are alone or grafted in gallic acid (GA) tagged silica nanoparticles on photodynamic antimicrobial chemotherapy (PACT) is investigated toward Staphylococcus aureus (S.aureus) and Escherichia coli (E.coli) in both planktonic and biofilm forms. Complex 4, bearing a total of 8 cationic charges, displayed the highest activity with log CFU (colony forming units) values of 8.60 and 6.42 against E.coli and S.aureus biofilms, respectively. The surface stability of E.coli and S.aureus biofilms in the presence of 4 and its conjugate was analyzed using cyclic voltammetry. Scanning electron microscopy (SEM) and Raman spectra are also used to study the conformational and biochemical changes within biofilm upon subjecting them to PACT.

FAMSA is a non-profit organization providing vital services to people in families while providing them with psychosocial and emotional support. FAMSA has been in existence since 1954. To achieve this aim, the study’s objectives were underpinned by understanding the implementation of the Department of Social Development’s Fatherhood Strategy in Buffalo City Metro, establishing FAMSA’s response to the implementation of the Department of Social Development’s Fatherhood Strategy as well as exploring the challenges faced by FAMSA in implementing the Department of Social Development’s Fatherhood Strategy. A qualitative research methodology was implemented to gather information from FAMSA and DSD. Findings from literature revealed that the fatherhood strategy has been a concern worldwide evidenced by the high levels of father-child non-residency. Data from this study revealed that FAMSA had been implementing the programme effectively regardless of numerous challenges that include funding human resources. Conclusively, a lot must be done to advocate for fatherhood. Recommendations also point to the need for several interventions which need to be done in research, social work practice and also policy formulation and development. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2023

- Description: Many studies addressing methods to improve reading comprehension in English Language Learners (ELLs) primarily focus on WEIRD (Western, Educated, Industrialized, Rich, and Democratic) samples. Unfortunately, ESL teachers in global South regions like Namibia have often been overlooked in this research. This study aims to bridge this gap by examining the self-developed strategies employed by Grade 7 ESL teachers to enhance reading comprehension in primary schools within Namibia’s Oshikoto region. This research adopts an exploratory case study approach with an interpretivist orientation. The selection of five Grade 7 ESL teachers is done purposefully, and data collection involves stimulated recall interviews and classroom observations. To analyse the collected data, an inductive thematic analysis is applied.

- Description: This paper examines the conceptions of ‘number sense’ as promoted in pre-service primary mathematics education courses at 11 South African Higher Education Institutions through the texts used by academics or prescribed for students. While all the participating institutions agree that the development of primary school learners’ ‘number sense’ is central to their mathematics methodology courses and that there is an overwhelming amount of research and literature on ‘number sense’ nationally and internationally, their conceptualisations of the nature of ‘number sense’ vary. Teacher educators, who develop pre-service teacher education courses, were asked to provide the texts, used to underpin the 11 universities’ mathematics education modules in the Bachelor of Education (Foundation and Intermediate Phases) and Post Graduate Certificate in Education (Foundation and Intermediate Phases) programmes. These texts were analysed drawing on Whitacre et al.’s emphasis on three ‘number sense constructs’ identified as Innate Number Sense, Early Number Sense and Mature Number Sense. The results show that there is no common language of description for ‘number sense’ across the 11 universities. This research implies that there is a need to develop a consistent understanding of ‘number sense’ and how it is developed across institutions.

- Description: The information on great white sharks is used by scientists to help better understand the marine organisms and to mitigate any chances of extinction of great white sharks. Sharks play a very important role in the ocean, and their role in the oceans is under-appreciated by the general public, which results in negative attitudes towards sharks. The tracking and identification of sharks are done using manual labour, which is not very accurate and time-consuming. This paper uses a deep learning approach to help identify and track great white sharks in Cape Town. A popular object detecting system used in this paper is YOLO, which is implemented to help identify the great white shark. In conjunction with YOLO, the paper also uses ESRGAN to help upscale low-quality images from the datasets into more high-quality images before being put into the YOLO system. The main focus of this paper is to help train the system; this includes training the system to identify great white sharks in difficult conditions such as murky water or unclear deep-sea conditions.

The tracking and identification of sharks are done using manual labour, which is not very accurate and time-consuming. This paper uses a deep learning approach to help identify and track great white sharks in Cape Town. A popular object detecting system used in this paper is YOLO, which is implemented to help identify the great white shark. In conjunction with YOLO, the paper also uses ESRGAN to help upscale low-quality images from the datasets into more high-quality images before being put into the YOLO system. The main focus of this paper is to help train the system; this includes training the system to identify great white sharks in difficult conditions such as murky water or unclear deep-sea conditions.

- Description: Scientists use bull shark data to better understand marine organisms and to reduce the likelihood of bull shark extinction. Sharks play an important role in the ocean, and their importance is underappreciated by the general public, leading to negative attitudes toward sharks. The tracking and identification of sharks is done by hand, which is inefficient and time-consuming. This paper employs a deep learning approach to assist in the identification and tracking of bull sharks in Mozambique. YOLO is a popular object detection system used in this paper to aid in the identification of the great white shark. In addition to YOLO, the paper employs ESRGAN to help upscale low-quality images from the datasets into higher-quality images before they are fed into the YOLO system. The primary goal of this paper is to assist in training the system to identify bull sharks in difficult conditions such as murky water or unclear deep-sea conditions.

- Description: Food constitutes a key component of a number of fundamental welfare dimensions, such as food security, nutrition and health. It makes up the largest share of total household expenditure in low-income countries, accounting on average for about 50% of the households’ budgets. Most demand analysis use existing models, but this study applied a new model – SEDS to analyse food demand among farming households in South West Nigeria. A multi-stage sampling technique was employed study to select 342 respondents. Primary data was collected through the use of a structured questionnaire. Data collected include information on a number of different food groups consumed by households, socioeconomic characteristics, demographic factors and income. The analytical techniques used were descriptive analysis and the Substitution Elasticity Demand System (SEDS). The result of SEDS shows that own price elasticities were less than 1 except for root and tuber, and fats and oil. It was found that cereals, legumes, fruit and vegetables and animal protein were price inelastic, i.e. necessities, and roots and tubers and fats and oils were price elastic, i.e. luxury goods.

- Description: Small and medium-sized enterprises (SMEs) face obstacles in raising capital and accessing financial services due to information asymmetry, high transaction costs and lack of collateral. FinTech developments have made gathering and sharing information easier, changed how funds are mobilized and allocated, and increased capital-raising activities. This paper conducts a systematic literature review on FinTech and SME financing for the period 2008–2022. So far there are unstructured and separate publications on this topic. Therefore, there is a need to consolidate the empirical research and their findings on the effectiveness of FinTech in meeting SMEs' financing needs. The bibliometric findings show that few studies on FinTech and SME financing are empirical in nature. These empirical studies surged a decade later after FinTech 3.0 started in 2008, with the majority of them using quantitative methods based on data from surveys and FinTech platforms. Furthermore, emerging alternative digital financing to SMEs have attracted more empirical studies than those on FinTech and bank lending to SMEs. In terms of publications, China is dominating, followed by the United States. The content analysis shows that FinTech has increased the ability of financial and non-financial institutions to collect and process accurate information about SMEs, thus reducing information asymmetry and transaction costs. FinTech has also increased the speed and quality of the lending cycle, from establishing an SME pipeline, collecting and processing information, to loan screening, monitoring and repayment. Finally, the paper presents research gaps and areas for future studies, challenges and policy recommendations on this novel subject.

- Description: Urban foraging is a global informal phenomenon which has been investigated in the Global North more than oth-er parts of the world. Characterising the nature of urban foraging in the Global South is imperative given the rapid urbanisation and sustainable development priorities in the region. In this study, we interviewed 80 urban forag-ers in four cities in the eastern coastal region of South Af-rica, with an aim to understand the nature of urban forag-ing in a developing nation context. We asked foragers about their initiation to and motivations for foraging, their logistics, yields and associated activities, descriptions of their foraging grounds, and if and how they had changed, and what they envisage as an ideal future for foraging.

- Description: The chapter seeks to embark on a qualitative study with first-year male students from a public university in South Africa to understand their adjustment and adapting to university life due to challenges with gender and sexuality matters that they face. The authors is mostly interested in male students as they are the usual perpetrators of gender and sexuality offences in universities. With this chapter, the author wants to understand the experiences of these students as they transition from one world (their hometowns) to another (university campuses). Of interest in this study is that some of the students at this university come from previously disadvantaged backgrounds: villages, townships, and farmsteads. Some of them have gone through traditional rites of passage such as initiation schools; others come from patriarchal backgrounds and heteronormative backgrounds.

- 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: This paper explores Grade R teacher expressions of themselves as teachers of numeracy, and as teachers working in the transition phase of schooling, after their participation in a research-informed numeracy-focused professional development (PD) intervention. The Early Number Fun (ENF) programme had 33 teachers from 17 Eastern Cape schools participating monthly over 18 months. Inclusion of Grade R to schooling is relatively new following policy changes in Early Childhood Development. In-service support tends to be subsumed within the Foundation Phase without attention to the specialised nature of Grade R that emphasises learning through play. ENF focused on the development of specialised teacher knowledge to support the development of early number sense through play, particularly with conceptual manipulatives. Data sources include three pre-, during, and post-PD questionnaires. Findings reveal that participation in ENF, and access to multiple research informed numeracy resources, supported teachers in their relationship with numeracy and the teaching thereof. Questionnaire responses indicate greater confidence in themselves as knowledgeable teachers of numeracy and that belonging to the ENF community supported navigation of positive professional identities within the mixed messages of policy. The findings contribute to the community-supported field of Grade R PD research and early numeracy teaching and learning. In concluding we discuss implications of this research for Grade R PD and for policy.

- Description: We surface a historical, political, spiritual, economic and cultural analysis made by five Xhosa Grandmothers based in the Eastern Cape, regarding their entangled relationship with the Ocean. A nuanced, complex relationship with the ocean and the politics of natural resource management in South Africa emerged from our interviews, as scholar-activists, with these Grandmothers, and this chapter attempts to explore how a gendered upbringing, with its associated roles and responsibilities, have created a unique relationship with the ocean that must be understood in all its nuanced and complex facets. We explore how the identities and values of these Xhosa Grandmothers are relationally entangled with the ocean and politics of South Africa, and explore the deep ecological knowledge that they hold, yet is shamelessly ignored. Through their own renderings, we unpack the rich understanding of marine species, customary rights, ocean policy and governance practices that impact, impede and complicate their lives. Working with first-hand accounts (stories translated from Xhosa), the Grandmothers provide a nuanced and brazen analysis of the status quo of ocean governance, ocean literacy and policy. They unpack what interventions are needed, and call for a response that recognises Grandmothers as central to South Africa’s wellbeing, a health that sits precariously with the complex realities of older women’s entangled and diverse vulnerabilities. Finally, the firsthand accounts and analyses made by the Grandmothers, offer a politically rigorous contribution to the field of hydrofeminism, one told in their own way, using their own idiomatic rendering, with their own metaphors and figurations.
