- Description: The study explored the experiences of children who have transitioned into foster care, looking in depth at their level of participation in matters concerning their lives. The researcher was predominantly inspired to conduct this research by children in communities who found themselves falling unintentionally into a system of foster care. There are overt hardships in communities that result in children needing care and protection. Children find themselves faced with abusive circumstances, experiencing loss and being abandoned. There is little research on experiences of children who have transitioned into foster care, on child participation in matters that involve their lives, and research that documents the perspectives of children. Children’s ability to exercise their constitutional right to participate, and making their voices heard regarding their life experiences through their own milieu, have also not received attention. There are several intervention systems put in place by the South African government to aid children in need of care and protection, and systems to place children in conducive environments. These systems are largely focused on placement of the child in need, application for foster care grants, foster parents, and the extension of the foster placement. However, there is very little information regarding the child’s right to participate in matters that involve their lives. The goal of the study was to investigate children’s participation in matters that affect their lives. It was interested in children’s perspectives. The aim was to explore the experiences of children who had transitioned into the foster care system in Breidbach Community in King Williams Town it Buffalo City Municipality. The purpose was to identify gaps, as there is minimal information concerning experiences of children who have transitioned into foster care and on children’s participation as stipulated within section 10 of the Children’s Act 38 of 2005. To be able to achieve the objectives of the study, interviews were conducted with purposefully sampled participants. Data obtained was analysed according to qualitative data analysis procedures. The researcher utilised exploratory, descriptive and contextual research designs. The domain where participants were interviewed was Breidbach, King Williams Town, and Buffalo City under the jurisdiction of the Department of Social Development (DSD) and Child Protection Organisations (CPO). Findings indicate the children lacked education on their right to participate in matters that affect their lives. Furthermore, some professionals did not involve the children in matters that affected them, leading to interventions on matters concerning the children that did not benefit from input by the children. Taking into cognisance of all the relevant information stated above, children’s right to participate in matters involving their lives is as paramount as the involvement of the social workers and the foster parents when determining their placement. A holistic approach has to be used, hence it is primary and recommended that, the investigation, intervention strategies and framework used by social workers in making sure that children in need of care and protection include the perspectives of children who are to be placed into foster care. This will be possible through the participation of a child. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: The purpose of this study is to investigate how Local Economic Development (LED) in Mnquma, with a particular focus on Butterworth, has impacted the alleviation of inequality, underdevelopment and poverty among the poorest of the poor. The aim of the literature review is to analyse the existing knowledge about LED, its impact in the alleviation of inequality, underdevelopment and poverty among the poorest of the poor and the tangible concrete pointer that shows that all key sector role-players are participating in LED. This study is qualitative in nature and employs a case study as the research design. The convenience sampling technique was used to select seven municipal workers and eight members of the community, giving a total of 14 participants. An open-ended interview schedule was used for the face-to-face in-depth interviews in order to collect data from the participants. Collected data was thematically analysed and raw data put set into meaningful segments, codes and categories. Themes were drawn from the responses of the participants and analysed. Some of the findings were that Butterworth municipality was seen as having both urban and rural features. On the other hand, it was found that the municipality did nothing to provide basic services to the people, the towns were dirty and streets lights were not working, there was insufficient representation based on the number of councillors elected under the Mnquma Local Municipality, municipality councillors lack skills, do not give feedback to the communities and need to be capacitated. The study also found that: ward committee members are less involved in the governance of the local municipality; there is a prevalence of high level unemployment and poverty in the municipality. However, there are various expanded Public Works Programmes currently going on in the municipality. The researcher made some recommendations to ensure effective LED with regard to the alleviation of inequality, underdevelopment and poverty among the poorest of the poor of the Mnquma area in the Butterworth municipality. , Thesis (MA) -- Faculty of Business and Economic Sciences, Development Studies, 2021

- Description: Quantity surveying firms are a crucial part of the construction industry because they are involved in the financial aspects of the projects, and their role and benefits have been documented across various studies. Furthermore, they provide services such as estimating, cost control and feasibility studies in numerous industries and these services are not limited to the construction industry. They are crucial in ensuring that the project proceeds according to budget, quality and time. Despite the noted benefits of quantity surveying firms, there has been a noticeable decline in the survival rate of the firms over the past ten years. It has been documented that several external and internal environmental factors affect the firms and thus have caused a decline in the survival rate. The volatility of internal and external forces that affect the industry has formed the basis of this study. Previous studies have failed to highlight the strategies to reduce threats and utilise opportunities. This study aims to establish common internal and external environmental factors affecting quantity surveying firms and determine these firms’ strategic architecture. A qualitative study was conducted using semi-structured interviews to assess the internal and external environment and strategic nature of Quantity surveying firms. In addition, a thematic analysis was administered to identify themes. The themes that arose from the external business environment were technology, political instability, tendering irregularities, lack of availability of work and the practice of green building. The technology theme highlighted the respondents’ views of the technological environment and the role of BIM and other software. Tendering irregularities threatened prospective tenderpreneurs as the respondents viewed the process as flawed and requiring better regulation. Lack of work was highlighted as a further factor. Although not many respondents mentioned this theme, green building is an emerging theme within the South African market. Two main themes were identified in the internal business environment: fee discounting and human resources. Fee discounting refers to the reduction of fees to secure work, while human resources were highlighted as an important factor and are regarded as the fuel that keeps the organisation running. Owing to the varying nature of factors within the external and internal business environment, it was concluded that there is no formal generic strategy that can be utilised to mitigate internal and external environmental factors. The client relationships were highlighted as an important factor, while client relationships were discussed under the balanced scorecard section of the study. The two main themes derived from the balanced scorecard were the financial perspective and client relationships under customer. Increased revenue per customer and venturing into new markets were the main themes mentioned within the financial perspective. The importance of nurturing client relationships was identified as an important factor under the customer section of the balanced scorecard. iii | P a g e The findings of this study will assist the stakeholders within the built environment in determining common internal and external environmental issues facing the industry. The recommendation will assist stakeholders in establishing probable solutions that can be implemented to overcome these challenges. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: With the substantial number of new malware variants found each day, it is useful to have an efficient way to retrieve Indicators of Compromise (IOCs) from the malware in a format suitable for sharing and detection. In the past, these indicators were manually created after inspection of binary samples and network traffic. The Cuckoo Sandbox, is an existing dynamic malware analysis system which meets the requirements for the proposed framework and was extended by adding a few custom modules. This research explored a way to automate the generation of detailed network-based IOCs in a popular format which can be used for sharing. This was done through careful filtering and analysis of the PCAP hie generated by the sandbox, and placing these values into the correct type of STIX objects using Python, Through several evaluations, analysis of what type of network traffic can be expected for the creation of IOCs was conducted, including a brief ease study that examined the effect of analysis time on the number of IOCs created. Using the automatically generated IOCs to create defence and detection mechanisms for the network was evaluated and proved successful, A proof of concept sharing platform developed for the STIX IOCs is showcased at the end of the research.

- Description: Rhodes University has a diversity of sustainable development initiatives meant for students and in a range of cases activities are initiated by students themselves with the support of the university. Results of a sustainability assessment revealed the involvement of students in environmental societies, environmental awareness campaigns, campus sustainability initiatives and community sustainability projects. Though most of the projects are still in their infancy and some challenges are yet to be overcome, the sustainability initiatives are gaining momentum and have contributed to improving the overall picture of sustainability at the university. Based on the results of the Rhodes University case study, the underpinning viewpoint in this paper is that university students are not merely recipients of Education for Sustainable Development but have the capacity to become agents for social change.

- Description: Elucidation of evolutionary factors that enhance protein thermostability is a critical problem and was the focus of this work on Thermus species. Pairs of orthologous sequences of T. scotoductus SA-01 and T. thermophilus HB27, with the largest negative minimum folding energy (MFE) as predicted by the UNAFold algorithm, were statistically analyzed. Favored substitutions of amino acids residues and their properties were determined. Substitutions were analyzed in modeled protein structures to determine their locations and contribution to energy differences using PyMOL and FoldX programs respectively. Dominant trends in amino acid substitutions consistent with differences in thermostability between orthologous sequences were observed. T. thermophilus thermophilic proteins showed an increase in non-polar, tiny, and charged amino acids. An abundance of alanine substituted by serine and threonine, as well as arginine substituted by glutamine and lysine was observed in T. thermophilus HB27. Structural comparison showed that stabilizing mutations occurred on surfaces and loops in protein structures.

- Description: In post-development theory, ubuntu is often cited as an example of an “alternative to development”. This article investigates whether ubuntu can play this role and what to think of the demand for alternatives to development in general. In order to do this, the paper fi rst deals with central aspects of postdevelopment theory and the debate about ubuntu. Although the concept fi ts well into a post-development perspective, the attempts to contrast ubuntu with Western ideas and ways of life are often fueled by the desire to rekindle an original, pre-colonial, authentic African philosophy. Yet discourses on Africa are always embedded in Western discourses, so this opposition reproduces precisely those dichotomies it aims to fi ght. More generally, this also holds true for the idea of “alternatives to development”, which postulate an essential opposition to “development”. This, however, denies claims for equal rights and participation at the root of demands for “development”. The struggle for these claims cannot be fought beyond the existing global order. Instead of engaging in romanticizing projections about an Africa beyond “development”, people’s views and needs should be taken as the starting point for the struggle against injustice and inequality.

- Description: The effects of melatonin, a known free-radical scavenger, on paracetamol in the presence of UV irradiation was studied by use of HPLC. The experiments were performed in air and nitrogen. The results show that the rate of photodegradation of melatonin is faster in air than in nitrogen whereas that of paracetamol is similar in air and nitrogen. When the two drugs were combined, melatonin retarded the degradation of paracetamol for up to 6h in the presence of nitrogen. However, in the presence of air melatonin rapidly enhances the photodegradation of paracetamol. This study shows that a combination of melatonin and paracetamol in the presence of air and UV irradiation can lead to rapid inactivation of both agents, thus raising important concerns about the possible use of melatonin as sunscreen

- Description: Histological examination of gametogenesis revealed that the current staging criteria used to assess gonadal recrudescence of the redeye labeo, Labeo cylindricus, were adequate. Gametogenesis was qualitatively similar to that of freshwater teleosts with a clearly defined seasonal reproductive cycle. L. cylindricus undergoes seasonal gross morphological and cytological gonadal changes with previtellogenesis dominating during the winter, vitellogenic development during spring and summer culminating in large-scale spawning at the end of summer. Post-spawning mass atresia of oocytes was evident in autumn. The histological data presented support macroscopical evidence that L. cylindricus is a synchronous iteroparous spawner, reproducing over a short period each year throughout its life-span.

- Description: Education in South Africa is said to be in crisis in recent years as many learners cannot pass standardised tests at the correct grade level. This has encouraged the South African Government and the Department of Basic Education (DBE) to introduce technology, specifically Tablet PCs, into education to improve learning outcomes in South African government schools. Furthermore, because of the coronavirus pandemic that started in 2020, educators were increasingly expected to find alternative, digital, online methods to continue teaching learners. Thus, the need for remote or distance education suddenly became an important factor in creating a need for online, remote learning. Against this backdrop this study aimed to determine how and in what ways educators could be supported to promote effective use of Tablet PCs both in the classroom and for distance learning. This study used Action Design Research to develop a guide based on both theory and the results gathered from the educator participants at a local secondary government school in Makhanda, South Africa. The finalised guide presents recommendations to educators, principals, and the DBE to promote acceptance and adoption of technology in the classroom and for distance learning. These recommendations include the provision of data, technological training and pedagogical support, a functioning community of practice, an online learning community of practice, and support from the DBE. Other enrichment factors were also recommended. , Thesis (MCom) -- Faculty of Commerce, Information Systems, 2021

- Description: Commercial drivers have been identified as eliciting behaviours that promote non- communicable diseases and road traffic accidents. The aim of the study is to determine the prevalence and pattern of alcohol use, smoking and physical inactivity among commercial taxi drivers in Buffalo City Metropolitan Municipality, South Africa. A cross-sectional study was conducted among 403 commercial drivers using the face-to-face interviews method. The WHO STEPwise questionnaire was used to obtain the demographic data, self-reported rate of alcohol consumption, tobacco use and physical inactivity. The participants’ mean age was 43.3 ± 12.5 years. About 30% of the participants were daily smokers, 37% consumed alcohol regularly and only 18% were physically active, whilst 82% were physically inactive. The prevalence of alcohol use, smoking and physical inactivity is high among commercial drivers in East London. Workplace health education on the health effects of these lifestyles’ risky behaviours on individuals and the general public should be given to the drivers.

- Description: Arbor Day, or Week, is a well-established greening initiative worldwide, focusing on tree planting and the benefits thereof. Frequently most effort is targeted at institutions such as schools and community groups. Yet there has been limited assessment of the success of Arbor Day, or Week, activities both at the schools, or the wider dissemination in neighbouring communities and suburbs. The objective of this study was to determine the influence of school-based Arbor Week activities on learners’ home-based practices regarding tree planting and urban forestry. Learners from three schools in Grahamstown South Africa, with good Arbor Week participation, were assessed on their tree planting knowledge. The learners’ parents were also interviewed to determine whether the information obtained by the learners at school was taken home. A control group consisting of people with no children or very young children was also assessed. This study found that Arbor Week activities were, for the most part, successfully taught in the case study schools, and most of the learners stated that their knowledge of trees and their benefits came from their school activities. However, many learners could not remember the activities in which their schools partook the previous year. Whilst most learners were aware of the importance of trees, few had encouraged tree planting at home. However, over one-fifth of adults claimed that their knowledge of the benefits of trees was as a consequence of Arbor Day activities when they were young. Numerous constraints to tree planting were provided by learners and both the adult groups, the two most frequent being limited space and falling leaves making their yards untidy. External organisations should become more actively involved and provide much needed support systems if greening initiatives are to reach the wider community.

- Description: This treatise compared the tax treatment of lease transactions in South Africa, Australia, and Nigeria from both the lessor and lessee perspective. The analysis revealed that there are similarities and differences in the tax treatment of lease transactions between South Africa, Australia, and Nigeria. In particular, one major difference was that unlike Nigeria, South Africa and Australia have not aligned the income tax treatment of lease transactions with the accounting treatment of lease transactions in terms of IFRS 16. Consequently, the research concludes that certain parts of the tax treatment of lease transactions in South Africa may be deemed to be inadequate as a result of the misalignment between the income tax and accounting treatment of lease transactions and the inconsistency between the income tax and VAT treatment of lease transactions. This research proposes that the South African income tax treatment of lease transactions be revised by aligning the income tax treatment of lease transactions with the accounting treatment of lease transactions for simplicity purposes, and that the inconsistency between the income tax treatment and the value-added tax of lease transactions be eliminated. , Thesis (MCom) -- Faculty of Business and Economic Sciences, Accounting, 2021

- Description: A total of 141 Polydactylus quadrifilis were sampled from the Kwanza Estuary in Angola ranging in size from 436 to 1360 mm fork-length (FL). Of these, 124 were male, six intersex and 11 female. Female fish were significantly longer (mm, FL) and heavier (kg) than males and had significantly higher gonadosomatic indices (GSI’s) than those of males and intersex fish. Transitional (intersex) gonads were delimited, with testicular and ovarian regions separated by connective tissue. The first signs of ovarian tissue appeared on the outer ventral surface of the gonad. A second layer of ovarian tissue was first noticeable at either end of the initial ovarian region and developed back towards the centre of the ventral wall to form a luminal space. Early-stage oocytes were commonly found in the outer area of male regions and residual late-stage spermatids and spermatozoa were found in the luminal space of ovarian regions, suggesting a process of sex change from the outside inwards. A loss of male function was noted with increased ovarian prevalence. Based on this evidence it is suggested that P. quadrifilis in the Kwanza Estuary are protandrous. Owing to the reliance of P. quadrifilis on large highly fecund females for egg production, it is likely that they will be sensitive to fishing practices that target larger individuals within the population.

- Description: We report phototransferred thermoluminescence (PTTL) and thermally-assisted optically stimulated luminescence (TA-OSL) of α-Al2O3:C,Mg annealed at 1200 °C. PTTL is TL measured from an irradiated phosphor after its exposure to light. The other theme of this study, TA-OSL is the additional amount of luminescence optically stimulated from a sample over and above the amount that would be measured at room temperature. A sample irradiated to 10 Gy and preheated to 230 °C at 1 °C/s followed by illumination by 470 nm blue light produced four PTTL peaks at 53, 80, 102 and 173 °C. The PTTL peaks occur at the same positions as the corresponding conventional TL peaks. Their kinetic parameters are also similar. The intensity of the PTTL peaks increased with duration of illumination to a maximum within 200 s for doses between 1 Gy and 10 Gy. The dose response of each of the PTTL peaks at 80, 102 and 173 °C is linear within 1–15 Gy. The rate of fading is low and the peaks are reproducible. When the irradiated sample is optically stimulated at temperatures between 30 °C and 300 °C, after preheating to 500 °C, the intensity of its TA-OSL goes through a peak with temperature at 200 °C. Using the rising edge of the plot, activation energy of thermal assistance for a deep electron trap was estimated as (0.21 ± 0.02) eV. The TA-OSL dose response is sublinear from 10–250 Gy and saturates thereafter. The PTTL and TA-OSL analyses signify that the concentration of deep traps in α-Al2O3:C,Mg increased after annealing at 1200 °C. As a result, the sample produced better PTTL and TA-OSL response than when annealed at lower temperature.

- Description: The global energy transition slowed in 2019 according to the Energy Transition Index report from World Economic Forum, and South Africa (SA) was ranked one hundred and fourteenth out of the one hundred and fifteen countries assessed South Africa thus demonstrated low results in both the energy system performance index and the readiness for energy transition. A range of countries are also facing challenges that are central to the transformation of the energy sector, including protecting the environment, energy security and climate change. These persistent global crises and problems experienced by the energy sector in relation also to scarcity of natural resources, widening social inequalities and environmental degradation, have necessitated reforms and transitions in the energy sector. This study follows an interpretivism research philosophy because it is more suitable for a qualitative research methodology. The strategy of case study research is related to the paradigm of interpretivism approach and thus to the methodology of qualitative research. Various research strategies are used to gain in-depth knowledge, including the use of a case study research methodology to investigate a particular natural setting phenomenon. The research methodology with the embedded sub-units of analysis uses a single case study instrument. The primary unit of analysis considered for this study is the energy sector in South Africa in its current state. For this study, semi-structured interviews are utilised as the research instrument forming the primary data. Transition management and research propositions as conceptualised in this case study are theoretical concepts that management could use to positively influence the South African energy transition. SA is seriously impacted by the spread of the COVID-19 pandemic since the beginning of 2020. The online research approach used resulted in some limitations during data collection, not being able to conduct interviews face-to-face and inability to observe participants during data collection. The researcher also found limitations on accessing data from some of the energy experts recruited to participate in the research. Some reported being busy and not having time to fill out the questionnaires. The researcher carried out follow-ups and recruited new participants. Primary data was ultimately collected from a total of five energy experts who participated in the study against the initial plan for eight participants. Most energy transition studies have focused almost entirely on energy technologies choices. The research intends to contribute to the body of knowledge and provides solutions for management, government and energy sector stakeholders to build strategies to resolve the complex and persistent challenges that slow down the energy transition in South Africa. , Thesis (MBA) -- Faculty of Business and Economic Sciences , Business Administration, 2021

Primary data was ultimately collected from a total of five energy experts who participated in the study against the initial plan for eight participants. Most energy transition studies have focused almost entirely on energy technologies choices. The research intends to contribute to the body of knowledge and provides solutions for management, government and energy sector stakeholders to build strategies to resolve the complex and persistent challenges that slow down the energy transition in South Africa. , Thesis (MBA) -- Faculty of Business and Economic Sciences , Business Administration, 2021

- Description: Protected areas (PAs) are often conflict-ridden, but conflict resolution mechanisms are often constrained by little appreciation of the perceptions of the principal agents (PA managers and local communities) about such conflicts. Getting local people’s support in PA management efforts is considered important for achieving conservation and livelihood goals. Using data from 13 nature reserves in South Africa, this study explores the perceptions of reserve managers and local communities about their relationships and the existence and underlying causes of conflicts. The findings showed sharp contrasts in perceptions between reserve managers and local communities. Reserve managers generally perceived that there were no conflicts with local communities and that their relationship with them was positive while local communities thought otherwise, claiming conflicts were centred around restricted access to PAs, lack of benefits from PAs and communication problems. These findings have profound implications for conservation, especially considering the importance of getting local people’s support in PA management.
