- Description: The Agile software development methodology has progressed over time and has become the most popularly used methodology for many projects owing to its adaptable and advanced nature. Agile is an iterative and incremental method that supports project teams to maintain the growing demands of present-day organisations. In software development, it is imperative to build software that ensures a holistic user experience and meets requirements. Software Developers and User Experience Designers focus on users’ preferences and requirements while navigating an application through an approach called user-centred design (UCD). The purpose of Agile user-experience (UX) methods is to build user-centric software solutions using the Agile methodology. Literature indicates a scarcity of Agile-UX models to integrate user experience design processes effectively within Agile software development. Hence, the motivation for this study was to create a practical model for integrating user experience design processes into Agile software development for implementation by software development teams. Initially, the study defines the problem that formed the basis for the initiation of this research, followed by the research questions and objectives that are the fundamental portion of the development of this study. This study highlights the benefits and challenges of Agile-UX methods through a case study of Agile software development teams in South Africa. Furthermore, additional best practices are recommended. A survey questionnaire was distributed to software development teams to identify the various factors that lead to implementing Agile-UX methods. The distribution of the survey questionnaire supported the theoretical perspective of this study. Furthermore, Agile development (AD) and UCD are not easy to combine as UCD aims to understand users before software product development, and no activities are performed before development starts in AD. Lastly, a significant benefit is that user-centred software systems create and promote team collaboration and communication and, ultimately, successful software projects. , Thesis (MIT) -- Faculty of Engineering, the Built Environment and Technology, School of Information and Communication Technology, 2022

- Description: After South Africa became a democratic country, there was a shift in the labour and employment sector. This led to introduction of new labour laws which would be in harmony with the constitutional dream and objectives. As such, the BCEA was introduced to bring about change to the basic conditions of employment. As a result of this, new minimum wages policies and laws were enacted. The wages were to be determined by the following means: first way was by means of bargaining council agreements, the second way by means of statutory council agreements, and the third way by means of sectoral determinations. The sectoral determinations policy was introduced through the BCEA. The BCEA through the ECC promulgated sectoral determinations which was aimed to establish minimum wages and conditions of employment for workers in the sectors deemed to be vulnerable. A minimum wage was firstly adopted in New Zealand and in European countries as early as the 19th century. This policy was then widely adopted after the establishment of the International Labour Organisation. The purpose or aim of a minimum wage is to protect workers against exploitatively low pay and to ensure a just and equitable share of the profits of work, thus creating a minimum living wage for all those that are employed and in need of such protection. Minimum wages are also often used as a policy tool to reduce poverty and inequality, including between men and women, by advocating for equal pay for work of equal value. Convention No. 131 and Recommendation No 135 are the key international conventions that determine minimum wage fixing. Convention No. 131 and Recommendation No. 135 seek to ensure that the minimum wage is set at a certain level that allows workers and their families to meet their needs. Article 4 of Convention No. 131 requires the creation and maintenance of machinery adapted to national conditions and requirements whereby minimum wages for groups of wage earners covered under article 1 can be fixed and adjusted from time to time. However, the situation of minimum wages differs between developed and developing countries. This raises a concern, more particularly, whether developing countries can be able to adopt the minimum wage policy. This research makes investigate the adoption of iv minimum wage policy in developed and developing countries, and how it affected their socio-economic status. On about 2018, South Africa enacted the National Minimum Wage Act. This Act was aimed at establishing a floor of minimum wage for all employees. This Act was intended to promote and protect vulnerable workers who were left out from the previous wage policies. The long-term aim of a minimum wage was to remove the problem of poverty pay, which exists when the earnings from paid work do not result in a living minimum wage and fail to push people out of poverty. When this Act was enacted, the national minimum wage floor was set at R20 per hour. However, in EPWP, Domestic Worker, and Farm workers had lower rates because they were regulated by other laws. Furthermore, there were challenges of non-compliance by employers. The national minimum wage policy as a socio-economic tool has had an impact on several levels of the economy. This policy has contributed to either alleviation or elevation of poverty and unemployment. Therefore, this study looks at the impact the minimum wage has had on these 2 aspects of life. The research provides a specific asymmetric data of the impact of the policy in all sectors throughout the time since this policy was adopted. It further shows how the minimum wage policy intervention has been affected by covid 19 pandemic. This empirical evidence is provided by way of charts and graphs to demonstrate the changes that has occurred. At the end of the treatise a conclusion on how this policy has affected the South African economy is reached. Furthermore, recommendations on how economic risks posed by the minimum wage policy can be reduced. , Thesis (LLM) -- Faculty of Law, School of Mercantile law, 2023

- Description: The study sought to explore township economic performance and contribution towards economic development in Nelson Mandela Bay, using the circular flow of money model. The study surveyed households and businesses in one of the townships in Nelson Mandela Bay (Kwazakhele). The survey reached out to 100 households and 100 businesses, totalling 200 participants. Data were analysed using descriptive and inferential statistics. The current state of the township economy is not a desirable one. There are more leakages than injections into the township economy. More township residents (especially high-income earners) choose to shop outside the township for goods because the township does not have the goods that residents need. Key findings show that township businesses are small in nature, primarily sole propriety and operate informally in the streets. Most people who work, earn R3500 and below and spend most of their income on food and groceries. Supply for the most consumed products in the township comes mainly from outside the township, and there is no circular flow in the township economy. However, there are more people working inside the township than those who work outside the township. More essential goods are found in the township than before, so residents do not have to travel outside the township to get basic groceries and food. Other findings show that the government is not intervening enough to help the township businesses through policy implementation and financial aid. Businesses in the township do not pay taxes, and this can limit what the government can do to help them. There are other business constraints that are prohibiting the township businesses to reach the optimum level, and the top cited constraint is Crime. The study recommended that government should intervene by passing a bill like the Gauteng Township Economy Bill that aims at assisting township businesses. Households should come up with other streams of income through entrepreneurship so that they can not only depend on government social grants for income. Businesses should form bulk buying groups to increase buying power to be competitive. Lastly, businesses should seek alternative sources of power because electricity is expensive, and the load-shedding is prohibiting township businesses from running efficiently. , Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 2023

- Description: This study aimed to exam the implementation of the Department of Social Development’s Fatherhood Strategy by Families South Africa (FAMSA) Eastern Cape. 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: Waste tyre is becoming a global environmental problem due to challenges in its disposal management and the fact that it poses fire hazards and metal leaching risk. Waste tyre can also breed mosquitos if it traps water thereby becoming an environmental health problem. There is also a portion of unused tyre in a waste tyre that is valuable and should be recycled. In South Africa waste tyre recycling is in three industries, one of which is crumb rubber where waste tyre is applied into various sized particles called crumb rubber. Crumb rubber can be applied in environmental remediation as an organic and inorganic pollutants’ adsorbent. Considering the fact that South Africa’s environment is loaded with heavy metal pollutants due to contributions by mining and agriculture as examples, it is postulated that crumb rubber produced in South Africa could be used to remediate the environment of these toxic metals. In this study adsorption of Pb (II) and Cu (II) from the synthetic waste water using waste tyre crumb rubber produced in South Africa was studied. Crumb rubber was activated using aqueous NaOH (0.02%) to make crumb rubber wettable followed by it being treated with 0.02 % acidified KMnO4 for modification of its ability to sorp positively charged metal species. Trial sorption experiments on 50 mg / L Cu (II) were successful with sorption of over 70% in 250 minutes. Final optimization of the sorption of combined Pb (II) and Cu (II) was studied using a full factorial design and optimum conditions of sorption were found to be pH 5.4; [metal] 0.617 mmol / L for Pb (II); and pH 5.4; the optimization of Cu (II) was found to be pH 5.4; [metal] 0.777 mmol / L. In Pb (II) sorptions the mechanism of adsorption on the activated crumb rubber was found to be following the Freundlich model indicating that the adsorption seemed to occur on a multilayer adsorbent, while the mechanism of copper(II) adsorption on to the activated crumb rubber was found to be following Langmuir model, indicating that the adsorption seemed to occur on a monolayer. With adsorption percentages ranging from 98.2 % to 100.0 %, for Pb (II), the crumb rubber produced under the conditions of this study, can be used in South Africa for selective removal of Pb (II). , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2022

- Description: Over the coming decades, Africa is expected to experience disturbing effects due to climate change and increased land cover change due to human influences presenting a significant concern for the future well-being of human and biological systems, the latter being the foundation of ecosystem services supplied to humanity. Therefore, unprecedented transdisciplinary cooperation, coordination, and integration amongst researchers, government, and civil society are necessary to increase the resiliency of these systems. This study aims to provide an outline of the Africa Alive Corridors (AAC) as an essential model for the encouragement of sustainable development through Earth Stewardship science. These aims are accompanied by the quantification and forward modelling for land cover change of the Critical Zone over 10 Great Lake Basins across one of the AAC, the Western Rift Valley Corridor (WRVC), in East Africa between the years 2018 and 2060. This approach provides the foundation for implementing improved regional governance, better encouragement of sustainable development beyond the 2030 United Nations Sustainable Development Goals, and education programs, such as the AAC, that promote socio-ecological resilience through Earth Stewardship Science. The AAC archives a portion of East Africa as the WRVC, a corridor along the western branch of the East African Rift System that highlights twenty heritage nodes, primarily great lakes, mountain ranges, national parks, and biological hotspots. These heritage entities are associated with ca. 12-million-years of evolution and transformation of the East African topography and related African Great Lake (AGL) systems. The thesis defines the study area by delineating AGL basins intersected by the WRVC. Across these basins, land cover change analysis provides a platform for an integrated assessment of the projected health of the corridor region. Existing land cover datasets provide the initial conditions of the study area for 2008 and 2013. Land cover between 2008 and 2013 is cross-tabulated using the Land Cover Module in the Terrset software, followed by the iii delineation of sub-models and driver variable identification. The Multi-Layer Perceptron algorithm provides the transition potentials between tree cover, urban area, cropland, wetland, and open area classes. Change quantification and prediction using Markov Chain analysis are then established for 2018, 2030, and 2060. The model successfully simulated future land cover change and concluded that: (1) proximity to existing human activity, proximity to existing tree cover, and population are the primary drivers of change; (2) the dominant land cover of the ten lake basins for 2018 was cropland at ca. 48%, followed by tree cover at ca. 33%; (3) total anthropogenic change over the coming four decades equates to over ca. 52 000 km2 (5 200 000 ha), and particularly (4) an urban area is expected to increase by >130%. This assessment ultimately provides a platform for regional governance development at the basin scale and Earth Stewardship science in East Africa. These changes require transdisciplinary action from researchers to civil society. The AAC provides the foundation for understanding the dynamics of the systems that support life across broader spatial and temporal resolutions in Africa, highlighting the need for future generations to build socio-ecological resilience to anticipate challenges such as biodiversity loss posed by climate change and excessive land cover change. , Thesis (DSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Over the coming decades, Africa is expected to experience disturbing effects due to climate change and increased land cover change due to human influences presenting a significant concern for the future well-being of human and biological systems, the latter being the foundation of ecosystem services supplied to humanity. Therefore, unprecedented transdisciplinary cooperation, coordination, and integration amongst researchers, government, and civil society are necessary to increase the resiliency of these systems. This study aims to provide an outline of the Africa Alive Corridors (AAC) as an essential model for the encouragement of sustainable development through Earth Stewardship science. These aims are accompanied by the quantification and forward modelling for land cover change of the Critical Zone over 10 Great Lake Basins across one of the AAC, the Western Rift Valley Corridor (WRVC), in East Africa between the years 2018 and 2060.

- Description: I investigated potential links between the diversification of African primate lineages and the physical evolution of the continent. I compared published phylogenetic trees based on mitochondrial and nuclear DNA for five clades: (a) Lorisoidea (galagos and pottos); (b) arboreal guenon monkeys (Cercopithecus and its allies); (c) living apes (including humans); (d) Papionini (baboons); and (e) savanna or “vervet” monkeys (Chlorocebus). I compared primate divergence dates with the ages of tectonic events, patterns of climatic change, and their palaeo-vegetational consequences. Based on present primate distributions, I estimated likely geographic locations of the divergence events. Finally, I compared the phylogenetic patterns of the primate clades with hominin evolutionary scenarios. Phylogenetic comparisons indicated three time periods when rates of speciation increased across the five primate clades: the Eocene – Oligocene transition (34 – 32 Ma); the mid-late Miocene (10 – 5 Ma); and the Pliocene – Pleistocene transition (2.7 – 2.3 Ma). Concentrated bursts of lineage splitting indicate a broadscale causal relationship between environmental change and lineage divergence. Human evolution followed similar biogeographic patterns to those of other primate clades. Tectonic events, climatic changes and palaeo-vegetational shifts are intimately connected, and have synergistic effects on biotic diversity. Tectonic events influence climatic change through their effects on oceanic circulation, planetary temperatures and rainfall patterns. Additionally, tectonic uplift and erosion may create geographic barriers to organismal dispersal across the continent, increasing the likelihood of geographic separation of populations and speciation. Recently evolved primate species show high levels of hybridisation for several generations after their initial divergence. Genus Homo generated ~10 species over 2.5 Ma. The emergence of these taxa likely involved substantial hybridisation, as demonstrated by the presence of Neanderthal genes within the H. sapiens genome. I suggest that this hybridisation contributed to the difficulties palaeoanthropologists often experience in distinguishing fossil hominin taxa. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The purpose of this research is to determine the presence of the principle of fairness during criminal trials in South Africa. In determining the presence of the principle, this research will provide a short background on both the historical pre-constitution situation on the principle of fairness and the present situation on how courts in South Africa conduct themselves in the adjudication of criminal cases in ensuring fair criminal trials. The historical background partially highlights certain provisions of the Criminal Procedure Act in curtailing both the application of due processes and entrenchment of fairness during criminal trials. The arguments on the principle of fairness during criminal trials are discussed in tandem with the principle of the rule of law in the determination of the resolve our justice system has, and the use of designated legal instruments to assert the principle of fairness, for example, section 35(3) of the Constitution and the provisions of the Criminal Procedure Act 51 of 1977(herein referred "the Act") including the determination of the level of judicial interference, independence, and impartiality. The challenges of unfair trials are also explained against the concept of ubuntu which is a foundational element of fairness expressed and interpreted as such by the indigenous people living in South Africa. In the Port Elizabeth Municipality v Various Occupiers, the court describes the concept of ubuntu as part of a deep cultural heritage central to fairness and fair treatment of humans. The principle of fairness in our criminal trials is a transformative element shaped by our historical background. This is evident in S v Zuma which refers to section 25 of the Interim Constitution. The transformative element shaping principle of fairness is discussed in conjunction with section 35(3) of the new Constitution and case law. This research also notes the adversarial element of our criminal trials having considered some of the evidentiary burdens, for example, the onus of proof, rebuttal of evidence, proof beyond reasonable doubt, reverse onus, circumstantial evidence, presumption, and the adverse inference. However, these evidentiary burdens are addressed by section 35(3) of the Constitution and case law, for example the right to remain silent, the right to be presumed innocent, the right not to be compelled to give self-incriminating evidence, to be informed of the charge with sufficient detail to answer it, to choose, and be represented by a legal practitioner and to be informed of this right promptly. This work views the principle of fairness as a mechanism focussing on relegating unjustness and the ill treatment of accused persons during criminal trials to the dustbin of history. , Thesis (LLM) -- Faculty of Law, Department Criminal and Procedural Law, 2022

- Description: This study aims to explore the experiences of physically disabled students at institutions of higher. The research methodology followed in conducting this study is a systematic review. Thus, published literature from the period of 2000-2020 on the experiences of physically disabled students in South African institutions of higher learning was reviewed. Five articles which met the inclusion criteria were assessed for eligibility using the CASP criteria. The social model of disability is applied as a theoretical framework in exploring these experiences. A synthesis of results and findings of South African studies relating to physically disabled students in institutions of higher learning is provided. Themes that emerged in the study indicate that physically disabled students experience social exclusion related to architectural access barriers, attitudinal barriers, lack of support and discrimination in South African Institutions of higher learning, which impacts their overall physical access in these institutions. The study found that addressing these challenges and access barriers would result in positive experiences for physically disabled students on campuses. The study concluded that to improve the experiences of physically disabled students, institutional effort is necessary that is extensive both in scope and systematic in nature. For future studies, it is recommended that a qualitative study explore not just disabled students‟ lived experiences but also be inclusive of academic and support staffs‟ perceptions. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: This study is a psychobiography of a Black South African Woman, Milase Jumartha Majola (néé Moyake), herein fondly referred to as ‘Mrs Majola’. Mrs Majola is not an icon in the general sense, but yet a definite unsung hero for many in her community. In her 89 years, she has touched many people’s lives and left a vast imprint in the community. Mrs Majola has been identified as a psychobiographical subject for this study based on her exemplary and extraordinary endeavours, which contributed significantly to the psycho-social well-being of the youth and the elderly within Port Elizabeth townships (now known as Gqeberha). The main objective of this study was to explore and describe Mrs Majola’s psychosocial development. Her psycho-social development was studied through the PERMA Theory of well-being lens and transformed into a narrative to understand better what made her a remarkable individual. Data was gathered from primary and secondary sources to enrich the psychobiography and qualitatively analysed. The findings show that Mrs Majola could balance her life in a way supported by the PERMA Theory of well-being. Results demonstrate her ability to understand and manage her Positive (negative) emotions, Engagements, Relationships, Meaningfulness, and Accomplishments as a mother, co-worker and community leader, which created numerous success stories during her tenure. Even though Mrs Majola experienced many hardships in life, such as losing her husband at the young age of 39, she always stayed positive and successfully used her inner strength to motivate her to keep living her purpose in life. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2022

- Description: The general aim of this study was to investigate the aetiological factors that lead to suicidal attempts among the youth of Lusikisiki area in the Eastern Cape Province. A sample of hundred and fifty participants with an average age of 24 years old was selected using convenient sampling. Data was collected using self-administered questionnaires. After the data were collected, it was then analysed through descriptive and inferential statistics. Findings show that various factors lead to suicide ideation and suicide attempts among youth of Lusikisiki. Economic hardship, depression and substance abuse to name few, were found to be among factors that lead to suicide attempt. Based on the research findings, the researcher recommends that various stakeholders such as the Department of Social development should work in corroboration. Departments such as Department of Education and Sports, Recreation and Culture should make awareness campaigns that will psycho-educate youth in rural areas, possibly alleviating drug and substance abuse. Those awarenesses may also tap into strengthening psychosocial well-being of youth. Furthermore, Department of Social Development should come up with community outreach programs aimed at alleviating poverty as the contributory factor towards suicide attempt. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: One of the recommendations made by the South African Law Commission (SALC) (1997) when discussing the issue of child justice was that the justice system should aim to promote the well-being of the child and deal with the child in an individualised way. This dissertation discusses recidivism in children after completing the Rhythm of Life (ROL) diversion programme which aims at diverting children who conflict with the law away from criminal procedures to programmes that assist in behaviour modification. The study is inspired by the need to uncover the effectiveness of the programme and the challenges encountered when it is delivered. It is further motivated by the need to expose the reasons why children return to the criminal justice system after having attended the ROL diversion programme. Additionally, it seeks to gain perspectives of the probation officers’ and parents’ insights on the observed changes after the attendance of the programme. The study utilised a qualitative methodology with an interpretive and descriptive paradigm, which used in-depth interviews and focus groups as a method of data collection. The participants of the study were children who completed the ROL diversion programme, parents or guardians of children who completed the ROL diversion programme, and probation officers implementing the programme. The data was analysed and presented following the following four themes, i.e., factors contributing to recidivism by children after completion of the ROL diversion programme, diversion programme content, and completion of the diversion programme and the effectiveness of the ROL diversion programme. The literature consulted was broken up into; the historical development of diversion programmes and the inherent legislative framework, the magnitude and extent of recidivism of children after completion of the ROL diversion programme, and the factors which contribute to recidivism by children after completion of the ROL diversion programme. The reviewed literature further scrutinised the global, regional, and South African perspectives on managing young people, and lastly reviewed the benefits and challenges of diversion programmes in general. The study used the social learning theory as a theoretical framework to explain and discuss recidivism and the effectiveness of diversion programmes. This is a general approach to psychology and regards criminal behaviour as no different from any kind of behaviour as it is learned through the processes of observation, imitation and vicarious reinforcement and punishment. The findings of the study revealed that the impact of absent and or lack of father figures in the family influenced the children to get involved in criminal activities. The findings further indicated that probation officers face various challenges when facilitating the programme, such as substance abuse by children, lack of resources and functional aids, and the language as the facilitator guide is written in English. It was also discovered that parents from the sample used an authoritarian style of parenting, which exerts high expectations from children while providing little in the way of feedback and nurturance. Lastly, the findings indicated that the ROL diversion programme does modify the behaviour of children on completion. However, the main challenge is the environment the children return to after completion as it is assumed as a contributing factor to committing the crime. One of the recommendations is to strengthen parenting programmes and to introduce a programme for parents or guardians of children with serious behavioural challenges, another recommendation is the development of a risk assessment tool for young people, to assist probation officers in holistically dealing with children. Additionally, probation service practitioners should be provided by the government with the necessary resources to ensure that aftercare services are rendered effectively and efficiently. The researcher lastly recommends that probation officers conduct an intervention evaluation after the programme to identify children who could not understand the content of the programme so that additional methods of intervention could be employed such as casework. The study had the following conclusions; risk factors such as lack of parental support, substance abuse, peer pressure and bereavement were causes for re-offending in the children interviewed; the programme manual presents a challenge in terms of language, because the manual is written in English, and not all children can understand English; the issue of restorative justice was overlooked by probation officers when dealing with children when they re-offended. The study also concluded that the ROL diversion programme is effective to a certain extent, depending on how the children utilize the skills acquired from the programme, and as the parents reflected that they observed a change in their children’s behaviour post-diversion, while children also expressed that they learnt valuable life skills which made them resilient. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2022

The literature consulted was broken up into; the historical development of diversion programmes and the inherent legislative framework, the magnitude and extent of recidivism of children after completion of the ROL diversion programme, and the factors which contribute to recidivism by children after completion of the ROL diversion programme. The reviewed literature further scrutinised the global, regional, and South African perspectives on managing young people, and lastly reviewed the benefits and challenges of diversion programmes in general. The study used the social learning theory as a theoretical framework to explain and discuss recidivism and the effectiveness of diversion programmes. This is a general approach to psychology and regards criminal behaviour as no different from any kind of behaviour as it is learned through the processes of observation, imitation and vicarious reinforcement and punishment. The findings of the study revealed that the impact of absent and or lack of father figures in the family influenced the children to get involved in criminal activities. The findings further indicated that probation officers face various challenges when facilitating the programme, such as substance abuse by children, lack of resources and functional aids, and the language as the facilitator guide is written in English. It was also discovered that parents from the sample used an authoritarian style of parenting, which exerts high expectations from children while providing little in the way of feedback and nurturance. Lastly, the findings indicated that the ROL diversion programme does modify the behaviour of children on completion. However, the main challenge is the environment the children return to after completion as it is assumed as a contributing factor to committing the crime. One of the recommendations is to strengthen parenting programmes and to introduce a programme for parents or guardians of children with serious behavioural challenges, another recommendation is the development of a risk assessment tool for young people, to assist probation officers in holistically dealing with children. Additionally, probation service practitioners should be provided by the government with the necessary resources to ensure that aftercare services are rendered effectively and efficiently. The researcher lastly recommends that probation officers conduct an intervention evaluation after the programme to identify children who could not understand the content of the programme so that additional methods of intervention could be employed such as casework. The study had the following conclusions; risk factors such as lack of parental support, substance abuse, peer pressure and bereavement were causes for re-offending in the children interviewed; the programme manual presents a challenge in terms of language, because the manual is written in English, and not all children can understand English; the issue of restorative justice was overlooked by probation officers when dealing with children when they re-offended. The study also concluded that the ROL diversion programme is effective to a certain extent, depending on how the children utilize the skills acquired from the programme, and as the parents reflected that they observed a change in their children’s behaviour post-diversion, while children also expressed that they learnt valuable life skills which made them resilient. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2022

- Description: This study aimed to develop normative indicators for the Beery-Buktenica Developmental Test of Visual-Motor Integration (Beery VMI) for Xhosa speaking adults in the Eastern Cape with a grade 11 or 12 qualification from a previously disadvantaged educational background. Method: the sample size was 40 participants between the ages of 19 to 40 years old. The study used participants that had no cognitive impairments. This study used independent t-test analysis to compare test performance between the following categories: urban versus rural, males versus females, age group 19-29 versus 30-40. The Kruskall Wallis test was used to establish whether classroom size would have an impact on test performance. Results: This study revealed that there was a no statistical difference in performance between urban and rural participants, males and females, and classroom size. There was no statistical significance between the age categories 19-29 versus 30-40 on the visual perception and motor coordination supplementary tests. However, there was a statistical significance noted, between the age categories on the visual-motor integration test performance. Conclusions: it was concluded that the Beery VMI can be used with more confidence when assessing the Xhosa speaking population from disadvantaged educational backgrounds. The norms in this study cannot be generalized to other ethnic groups or populations. It was further recommended that more studies like this take place, and more norms are created for the South Africans using the Beery VMI. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: No formal study on the incidence and extent of medullated and coloured fibres has been performed in South Africa. The purpose of this research project was to investigate the validity of the claims that there has been an increase in the production of wool contaminated with medullated and coloured fibres. Therefore, the main aim of this study was to determine whether the incidence and extent of medullated and coloured fibres in the South African wool clip have changed over time. Secondly, the study aimed to determine whether the incidence and extent of medullated and coloured fibres have a distinct geographic distribution. This study explored eight years of wool production records (2010 to 2017) obtained from BKB, the largest wool broker in South Africa. For the purpose of this research, the wool-producing areas of South Africa were divided into 6 regions, according to average annual rainfall, vegetation type and major farming practices applied in the area. Statistical analysis of the data included descriptive statistics, analysis of variance and post-hoc tests, as well as regression analyses. This study succeeded in quantifying the extent and prevalence of contamination with medullated and coloured fibres in the South African wool clip. The overarching conclusions were: • Floating kemp is the most important contaminant of wool in South Africa, with the incidence of harsh kemp and coloured fibres being very low. • Generally, the most important areas that need attention in combatting contamination in the South African wool clip, are the Mixed Farming Summer Rainfall Region, the Semi-Arid Grassveld and the High Rainfall Grassland. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Micro contractors (MCs) in construction are pivotal to the growth of the South African economy. The South African construction industry has world-class H&S legislation and regulation; however, frequent accidents occur at an alarmingly high level. Accident statistics presented in this thesis paint a worrying picture of a vicious cycle of recurrent accidents and injuries in the South African construction industry. Whilst governments planned National Development Programme will provide opportunities for MCs, in hindsight there’s dire need to have solid foundation of H&S development prior to MCs expanding operations into small and medium sized enterprises. The grouping of very small contractors into MCs under the definition of Schedule 1 of the National Small Business Act (NSBA) may result in fewer Health & Safety (H&S) initiatives aimed at the MCs, given the turnover limit has a maximum of R10 million per annum. The topic incorporated ’reasonably practicable’, to identify what MCs currently know, and ought to know, about the hazards or risks on construction sites, and then develop a pragmatic framework to eliminate or minimise risk. MCs generally did not understand H&S regulations hence carried out tasks for the sake of compliance. Punitive measures and enforcement of H&S regulations have done little to reduce the number of accidents. The study provided context for management and employees at MCs to approach H&S in a logical approach without circumventing H&S regulations. The challenges affecting MCs determined that there’s need for specialised H&S legislation and regulation to be developed for MCs that factors socio-economic challenges of literacy, skills, affordability, and poverty. Consequently, structured methods of support by stakeholders in the form of support and mentorship would result in a significant improvement of MCs’ H&S performance. Standards such as the ISO 45001:2018 state that it can be implemented for all size of construction firms. Whilst this standard may be suitable for MCs in developed countries there exists a vacuum in terms of its applicability to MCs in South Africa. The main objective was to develop a framework for MCs that will help to reduce accidents while simultaneously improving sustainability and service delivery. ii The research adopted an interpretivism philosophical position, which is reliant on people's views and conduct. The research applied deductive reasoning by survey technique and to construct a theory of H&S issues and corrective measures through research questions. The study adopted a mixed method research approach using a survey sent to the members of the South African Institute of Occupational Safety and Health (Saiosh), persons registered with the South African South African Council for the Project and Construction Management Professions (SACPCMP), and members of the Association of Construction Health and Safety Management (ACHSAM), and using the thematic analysis of data from 16 interviews representatives of member organisations, H&S consultants, and PCs. Accident statistics obtained from the Federated Employers Mutual Assurance (FEM) were also analysed. The study findings indicate that a reasonably practicable H&S programme must be developed for MCs due to the ‘onerous’ requirements arising from the Occupational Health and Safety Act (OHS Act) and Construction Regulations (CR). The study determined that it would be unaffordable for MCs to implement and maintain the ISO 45001:2018 standard. H&S practices at MCs under guidance of a H&S practitioner can be deemed to be undertaken frequently, as opposed to infrequently, however, new entrant MCs struggled to comply with H&S legislation and regulations and that has resulted in a H&S culture being generally non-existent or difficult to establish. The significance of this study lies in the recommendations that are proposed. Effective H&S in MCs require greater support from the Department of Employment and Labour (DEL), member organisations and the PCs in construction. The study proposes that a national H&S logbook be set up to record H&S compliance and accidents at MCs. Furthermore, a phased approach should be instituted for improving H&S. These phases should include phase one, for new entrant MCs from zero to three years, phase two for MCs during the development and growth phase from three to five years, and MCs deemed competent with H&S should be encouraged or required to train and mentor new entrant MCs. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: The purpose of this dissertation is to explore the notion of skin, its functions, and dysfunctions as the basis for the conceptual as well as theoretical output of this work. The problem statement aims to establish whether cathartic relief can be achieved through the process of visualizing skin as the abject other. Every human and animal is born with skin. The epidermis is the outermost of three layers that make up the skin. This layer provides a barrier to infection from environmental pathogens and regulates the amount of water released from the body into the atmosphere through trans epidermal water loss (Bouwstra, 2003:34). Although the human skin serves as a protective barrier, the skin itself can be a source of physical as well as emotional pain. I was born with Epidermolysis Bullosa (EB), a rare and genetic skin condition that results in extensive blistering and wounding of the skin caused by mechanical trauma. The process of friction, wounding and healing has been a part of my physical being and daily affairs since I can remember. According to Cervero, ―Pain is our most powerful emotion, an essential learning tool, a major factor in our relationship with the world, and the source of much of our social behavior‖ (2012:34).I believe that my personal experience with EB has affected how I view the functions and importance of skin. In this study I explore the purposes and functions of skin through both a physical and psychological lense I also investigate the role skin plays in forming identity. The works of artists such as Frida Kahlo, Eva Hesse and Alina Szapocznikow are carefully considered in understanding different approaches and mediums used in engaging with the experience of catharsis. Investigations are made into theories on Abjection, the Skin-Ego, Materiality and Catharsis in order to sufficiently inform and shape the outcomes of the creative process. The creative and research processes have resulted in the body of artwork, entitled Skin- deep: transforming dysfunction into function, which is presented as a narrative installation and exhibition of abstract sculptural work. Ultimately, the body of work and research attempts to validate that the notion of skin (as the abject other skin) can be artistically explored to achieve cathartic relief. , Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 2022

- Description: The public sector in South Africa accounts for a huge amount of the public service jobs and it has been learnt that there is also a considerable amount of dysfunctional conflict that affects the public sector. The main aim of this study is to investigate the causes of conflict in the public sector, with specific reference to the department of Employment and Labour, in Port Elizabeth. The research objectives were as follows; firstly, to investigate the causes of conflict or potential conflict at the department of Employment and Labour in Port Elizabeth. Secondly, the research sought to ascertain government employees’ approach to conflict and how it affects their performance (management and subordinates) with specific reference to the department of Employment and Labour, in Port Elizabeth. Thirdly, the research also sought to come up with the recommendations with the view to address conflict or what might be causing conflict at the department of Employment and Labour in Port Elizabeth. Workplace conflict was used in this study as a conceptual framework to understand conflict in the department of Employment and Labour, in Port Elizabeth. The research has followed a qualitative approach to gather data. Using a purposive selection sampling technique, 12 semi-structured interviews were conducted with employees of the department of Employment and Labour, in Port Elizabeth. Ethical considerations were adhered to throughout the course of the study. The findings of this study have revealed that lack of consultation or lack of an inclusive or participative approach in dealing with matters is regarded as the main cause of conflict within the studied organisation. The organisations lack conflict management skills. This study can be of benefit to the organisation, in that its recommendations can assist the organisation place more attention on improving its conflict management skills, which may help reduce the negative impacts of unmanaged conflicts. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: Almost 90% of the primary global energy demand is serviced from the burning of fossil fuels (Abas, Kalair & Khan, 2015). Owing to the detrimental environmental impact of this, a global energy transition to the use of renewable energy, including solar energy, is needed (Gielen et al., 2019). An important aspect that inhibits the growth of solar energy is accurate solar resource data. Such data is needed because knowledge of the future reliability and quality of energy production is required to analyse a system’s performance and determine financial implications (Sengupta et al., 2017). Existing methods used to detect outliers in solar resource data do not efficiently identify outliers and an accurate and robust approach is required (Eastwood, 2019). Using simulated and real-world data, this study investigates the use of several classification methods, along with a two-stage clustering-classification approach to accurately identify outliers in solar resource data. The Treebag method proves to be an adequate outlier detection method for solar resource data. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2022
