- Description: The main aim of this study was to examine the meanings attached by locals to medicinal plants in Kabokweni, Mpumalanga and how such meanings tend to shape the character of local struggles over access to, use and even commercial benefits of medicinal plants. This study draws its theoretical schema from political ecology, especially ethnoecology where the goal is to elucidate environmental conflict, most especially in terms of contestations over knowledge, power and practice, as they relate to the meaning and control of medicinal plants in Kabokweni. The study, therefore, recognises the complex interconnections between nature and society through a careful analysis of what one might call the forms of access and control over resources and their consequences for environmental health and sustainable livelihood. In-depth interviews, oral histories and non-participant observation were used to collect data and thematic analysis was used to analyse the data into meaningful themes according to the research questions and objectives of the study. The study found that Swati medicinal plant names are not subjective, but depend on socio-cultural and pragmatic perspectives, and meanings shape local struggles over medicinal plants in Kabokweni. Four underlying discourses were identified from the analysis of local narratives on the meanings and uses of medicinal plants. Each discourse offered a noticeably different concept of medicinal plants and people-plant relationships. Firstly, the ‘sustainability discourse’ referred to the role of foresters and environmentalists in sustainably managing plant resources. Secondly, the ‘livelihood discourse’ was entrenched in the local culture and economy. Thirdly, the ‘knowledge discourse’ conceptualises medicinal plants predominantly in terms of species richness and natural processes, while the ‘economic discourse’ emphasised the economic potential of medicines derived from plants as their major concern. Powerful social actors who influenced decisions about use and management of indigenous medicinal plants controlled these discourses. Finally, the study argues that rural communities would continue harvesting natural resources, even if illegally. Hence, to avert conflicts between indigenous actors and environmental agencies, communities need to be integrated into management programs, so they can be aware of some crucial issues such as sustainable harvesting of medicinal plants. , Thesis (MSoc) -- Faculty of Social Science and Humanities, 2020

- Description: Objectives: The influence of detraining on the perceptual motor skills of soccer players has been theorized, but not verified empirically (Farrow & Robertson, 2017). The aim of this study was to examine detraining and its effects on the perceptual-motor skills of soccer players by employing a three-week period of no training, immediately post-season. Method: To further examine the effects that three weeks of no training would have on the perceptual-motor and perceptual-cognitive abilities of soccer players, sixteen male club university soccer players (aged 21.10±2.69 years with 12.40±3.18 years of playing experience) participated in this single-cohort longitudinal observation study. The measurements were performed in the following order with sprint testing encompassing the 40-Meter Sprint Test, aerobic performance testing by use of Intermittent Yo-Yo Test (YYIR2), perceptual-motor testing which consisted of the Loughborough Soccer Passing Test and perceptual-cognitive testing undertaken by means of Video-based assessment. Results: A three-week period of no training showed no negligible effects of detraining on sprint performance (F(2, 30) = 1.43, p = .255, ƞp2 = .09), perceptual-motor performance (F(1, 15) = 2.52, p = .133, ƞp2 = .14) nor effects of detraining regarding perceptual-cognitive aptitudes (F(2, 30)= 0.28, p= .813, ƞp 2= .01 ). Results of the study did, however, suggest the potential for increasing aerobic performance (F(1, 15) = 6.17, p = .025, ƞp2 = .29). Additionally, the study results inferred that within Video-based assessment, university club soccer players may develop a response bias due to familiarity or repeated exposure to the testing procedures. Conclusions: Results from the study fail to comprehensively show the effects of detraining on male club university soccer players in all aspects of the perceptual-skill framework, after three weeks of no training. The researcher further discusses the effects of familiarity, repeated exposure and the robustness of these perceptual-cognitive and perceptual-motor abilities as possible reasons for the results returned. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: The purpose of this study was to explore factors associated with lack of improvement in the health care provided towards achieving compliance with the National Core Standards (NCS) in King Sabata Dalindyebo (KSD) sub-district clinics, in OR Tambo District in the Eastern Cape. A quantitative design was seen as the most suitable for this study. This method was chosen as the one that would best assist the researcher to meet the objectives of the study. A purposive sampling method was chosen, according to which the researcher selected five sites; all clinics that had been previously inspected for quality standards by the Office of Health Standards Compliance at least once. Participants for the study were all employees of those clinics and one representative of the governing structure of each. Twenty-eight participants in total formed part of the study as two did not return their responses. For collecting data from the participants, self-administered questionnaires were used. Throughout the data collection process, ethical standards of nursing research regarding anonymity, confidentiality and privacy were adhered to. Collected data were analysed using the Statistical Package for the Social Sciences (SPSS) computer software. The distribution of results is presented in tables and bar graphs. The results of the study reveal that a quality-oriented culture is lacking in our clinics with poor participation of clinics teams in quality improvement processes. Leadership and management at clinic level need strengthening. It was also found that there is insufficient capacitation of departmental strategic shift innovations, revealed in the complete absence of information sharing and feedback regarding previous assessments. In addition, there is a shortage of resources including basic equipment in clinics. , Thesis (MPH) -- University of Fort Hare, 2018

- Description: Keratinous wastes are emanating in a million tons, as by-products, from various agro-industrial processing plants. Consequently, they create a serious solid waste problem in the environment due to poor handling. Microbial keratinases are proteolytic enzymes that effectively participate in keratin-rich biomass hydrolyses such as feathers, nail, hair, hooves, and horns. Therefore, proper management of these wastes via recycling into useful products is ecologically imperative. Biodegradation of keratin-rich biomass has been identified as an economical and environmentally friendly way of transforming these recalcitrant agro wastes into useful products, hence the motivation for this study. Feather degrading bacterial strains previously isolated from a municipal dumpsite and coded as SSB-02 and SSB-03 was identified through 16S rDNA sequencing and phylogenetic analysis. The fermentation conditions for keratinase production were optimized. The protein and amino acids constituents of the hydrolyzed chicken feather were analyzed. The biochemical properties of the keratinase produced were determined. Also, the effect of laundry detergents on the stability of the keratinase was studied. The isolates coded as SSB-02 and SSB-03 showed a high percentage of sequence homology with Exguobacterium spp., hence they were identified as Exiguobacterium sp. FBH5 and Exiguobacterium acetylicum FHBD, respectively. Exiguobacterium sp. FBH5 showed the highest extracellular keratinase production of 934.58 ± 27.27 U/mL at 72 h of incubation; in optimized fermentation conditions that included pH (5.0), temperature (30 oC), and chicken feather (0.5percent, w/v). Similarly, E. acetylicum FHBD displayed optimal keratinase production of 1023.64 ± 25.71 U/mL at 120 h of fermentation and improved fermentation conditions that involved pH (3.0), temperature (35 oC) and chicken feathers (0.5-1.5percent; w/v). The amino acid analysis showed that arginine, aspartic acid and glutamic acid were the most abundant amino acids cleaved from the degradation of chicken feathers by Exiguobacterium sp. FBH5 at a respective concentration of 1.16, 1.28 and 1.45 (g/100g sample). Additionally, hydrolysate that emanated from E. indicum FHBD degradation of feather showed high concentrations of arginine, serine, aspartic acid, glutamic acid, and glycine at the respective concentration (g/100g sample) of 1.2, 1.12, 1.34, 1.58 and 1.29. The keratinases were optimally active at pH and temperature of 8.0 and 50 oC, respectively. EDTA and PMSF did not highly repress keratinolytic proteases' activity, and this inhibitory pattern suggests that they may belong to a mixed protease family. Keratinase from E. acetylicum FHBD was highly stable in the presence of SDS, with 99percent residual activity and displayed variable stability in other chemical agents tested. A similar stability pattern was observed with keratinase from Exiguobacterium sp. FBH5, although the enzyme lost about 40percent of its original activity in the presence of SDS. Evaluation of metal ion stability indicated that E. acetylicum FHBD keratinase was remarkably stable in the presence of Fe3+, Mg2+, Cu2+, Zn2+, and Ba2+, with residual activity of 94percent, 88percent, 89percent, 90percent, and 97percent, respectively. Similarly, Exiguobacterium sp. FBH5 keratinase was considerably stable after treatment with Co2+, K+, and Zn2+ as it displayed a residual activity of 85percent, 84percent and 93percent, respectively. The study of the keratinases stability in laundry detergents showed that E. acetylicum FHBD keratinolytic proteases was activated in the presence of Omo, Surf, Sunlight, and Pro wash after 60 min of pre-incubation compared to 30 min, with residual activity of 94 ± 2.94percent, 91 ± 2.53percent, 95 ± 2.89percent and 87 ± 2.89percent respectively. Likewise, Exiguobacterium sp. FBH5 keratinase activity was promoted after 60 min of incubation compared to 30 min, with a residual enzyme activity of 79percent, 84percent, 101percent, 103percent and 105percent and 106percent for Ariel, Surf, Prowash, Freewave, Sky and Evaklin, respectively. Therefore Exiguobacterium spp., demonstrated excellent keratinolytic potentials that could be exploited for sustainable development of bio-innovative products. The study keratinases' properties suggest their industrial and biotechnological application potentials, especially as bio-additive in the formulation of laundry detergents. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

- Description: The main objective of this thesis is to investigate how conscious hip hop culture is used to reconstruct and influence urban youth identities in South Africa, in the case of Fingo Village, Makhanda. In addition, it aims to understand how the South African conscious hip hop scene, appropriated from the West, can be used to shape the identities of the urban youth, instead of the materialistic commercial/mainstream gangsta rap that is currently dominating popular culture and media today. Kellner’s (1995: 10) multicultural critical approach is appropriate for this thesis, as it “provides a critical multiculturalist politics and media pedagogy that aims to make people sensitive to the relations of power and domination which are encoded in cultural texts, such as those of television and film, or new technologies and media such as Internet, and social networking”. Moreover, in the words of Cvetkovich and Kellner (cited in Dolby, 2010:11), this dissertation “investigates the increasing influence of global popular culture and its possibility to equip the urban youth with new sources of identification”, as well as opportunities for social change. In Makhanda, rappers, community activists, B-Boy crews, graffiti artists, spoken-word poets, photographers, and journalists all assembled in Fingo Village for the social event Around Hip Hop, at the multipurpose Fingo square, between 2011 and 2019. Today, Around Hip Hop is an arts based organization that produces hip hop mixtapes, short documentaries, and educational events aimed at creating a cross-cultural exchange and increasing awareness of South African politics. Around Hip Hop has hosted various events, dialogues, and performances where hip hop is used as a cultural expression, which continuously creates spaces for the urban youth to rethink and reconstruct their identities; not only as artists, but as audience members as well. Events, such as The Return of the Cypher, Intyatyamo Elityeni, and Business beyond Fingo Festival all form part of Around Hip Hop. The Return of the Cypher is an open music event, where rappers, usually gathered in a circular formation with one or more artists performing in the middle, showcase their skills. Semi-structured interviews were conducted with eight local hip hop artists in Makhanda, in order to investigate how conscious hip hop is used to rethink and reconstruct urban youth identities. , Thesis (MA) -- Faculty of Humanities, Sociology, 2022

- Description: The purpose of this study was to explore small group teaching in the senior phase with the aim of identifying suitable approach of managing small group teaching. This study was triggered by persistent misunderstanding of small group teaching that continued to hover Kentani Education District due to poor performance of learners in the classroom. To understand all these challenges experienced by teachers this study employed qualitative approach using semi-structured interviews to collect and analyse data from participants in order to get a deeper understanding of the phenomena under study. A sampling procedure was used to select respondents from two junior secondary schools of deep rural areas. The two schools were purposefully sampled. Fifteen participants participated in this study from two sampled junior secondary schools. The data were presented, analysed and discussed. A lot of themes emerged from what the participants reported and similar experiences were noted as well as different experiences. The study sought to :( a) Explore teachers ‘understanding of small group teaching. (b) Find out different approaches of small group teaching. (c) Investigate challenges faced by teachers when employing small group teaching. (d) Explore what promotes effective facilitation of small group teaching. (e) Suggest a proposed teaching model that will assist senior phase teachers in enhancing the way they perform their small group teaching. Central to what this study ascertained is the relationship between the teachers and Subject Advisors .From the findings of this study, it can be ascertained that for any teacher to succeed and understand deeply the requirements of his her profession, he she needs to have a positive attitude towards hisher career, being guided, mentored, nurtured, monitored and supported by SMTs and Subject Advisors. , Thesis (MEd) -- Faculty of Education, 2017

- Description: The Eastern Cape remains the poorest and most rural province in South Africa. Roads in the province are generally in a poor condition and over the years they have been deteriorating, particularly in the rural areas. There is a general lack of regular maintenance of roads in most rural municipalities and in certain instances, this is exacerbated by the lack of resources. Intsika Yethu Municipality (IYM) is a rural municipality in the Chris Hani District served by a road network with a large number of gravel roads which are in a poor condition. The majority of the residents have sparse access to basic services and amenities. Consequently, they travel long distances, for at least an hour, to access services. The study adopted a quantitative research method. A structured questionnaire was designed to collect data and non-probability and probability sampling procedures were utilised. A detailed statistical data analysis was conducted to test probable relationships between variables utilised in the research tool. The findings of this study revealed that the gravel roads in the area are not maintained regularly. During rainy seasons the roads become slippery, while several are flooded and unusable. Such condition of roads makes the rural areas to be generally inaccessible to essential service workers i.e. teachers, and healthcare workers. The findings further revealed that most gravel roads in IYM have not been maintained in the past 5 years. The drive along the network of roads is poor due to structural defects. Furthermore, the vehicles are forced to drive at a relatively slow speed. The condition of the poor roads affects the response time of emergency service transport. The response time averages between 3-12 hours depending on the distance of the area from the main towns. The condition of roads results in increased transport and travelling costs. The poor quality of the roads in the area makes it unattractive to skilled essential workers which has a negative impact on the residents. The research concludes that if gravel roads are maintained regularly, residents’ access to amenities could be improved and their livelihood could be enhanced. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: Women who have terminated a pregnancy may identify shame, guilt, grief, and/or regret after the procedure. This study aimed to explore and describe the self-forgiveness process of women in the Nelson Mandela Metropole area who identified negative emotions such as guilt and/or regret after an abortion. The methodology followed an exploratory-descriptive, qualitative design, adopting Lincoln and Guba's (1985) model of trustworthiness. Participants were obtained through non-probability purposive sampling and data was gathered via semi-structured, online individual interviews on a face-to-face basis. Data gathered was analysed using Braun and Clarke’s (2006) thematic analysis. The findings reflected the participants’ perceptions of forgiveness and self-forgiveness, as well as the psychological experiences of women post-abortion. A self-forgiveness model developed by Enright and the Human Development Study Group (1996), as well as the stages of grief developed by Kübler-Ross and Kessler (2005), was utilised to conceptualise the psychological experiences and psychological healing of post-abortion women. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: This study evaluated South Africa’s legislative framework for public infrastructure investment to determine its effectiveness in reducing unemployment. The study is primarily driven by South Africa’s persistent challenge of unemployment with Statistics South Africa estimating the unemployment rate at 35.5 per cent or 7.9 million labourers. Persistently high levels of unemployment harm the socio-economy as unemployment increases poverty and contributes to inequality. For the government an increase in expenditure on social relief programmes, while offering some relief, decreases revenue collection. In order to mitigate this imbalance, the South African government identified public infrastructure investment as a stimulus for economic growth and create employment, such as in the Expanded Public Works Programme initiative. The legislative framework is an important aspect of study as policy is legitimised and implemented through the legislative framework. Previous studies have focused on the effect of fiscal policy on economic growth and employment creation. These studies have also used quantitative data analysis to explain the relationship between fiscal policy, economic growth, and unemployment. Other studies have focused on public policy planning and implementation, and some of the policies that have been implemented to address unemployment. This study focused on public infrastructure investments specifically rather than fiscal policy in general. The study also examined the legislative framework to determine whether it is effective in reducing unemployment through public infrastructure investment. The study made used qualitative data analysis as the researcher undertook a document analysis of publicly available documents which were sampled using a purposive sampling technique and analysed using the thematic analysis method. The findings of the study were that the legislative framework supported employment creation through public infrastructure investment through the establishment of a public institution to support the construction industry, the use of local content as inputs and labour-intensive technologies in the infrastructure delivery process. The legislative framework was not effective in supporting the policy, which is demonstrated by the perpetually high unemployment rate despite unemployment alleviating initiatives being implemented in the early and mid-2000s , Thesis (MSc) -- Faculty of business and economic sciences, 2023

- Description: This work addresses the role of mirroring and mirrors encountered while working with a patient obsessed with his appearance. At the same time, however, it also attempts to provide an understanding of the process of mirroring from the developing unborn child to the adult. It examines the womb as a reflective space, the mirroring role of the mother, psychological work as mirror work, the psychopathologies of disruptive mirroring and the nature of reflection as a story, confusion and a ghostly other, and finally, the relationship between mirror reflection and psychological life. What is examined and described in this process applies not only to the specific case in study but is relevant at a universal level to all of mankind regardless of race or religion. The case-study method was used to examine the process of therapy that took place over three months. The patient’s identifying data, reasons for referral, presenting problem, family background, basic personality, interpersonal relationships, mental state, diagnosis, dynamic formulation and rationale for psychotherapy were covered in detail. The process of psychotherapy over 27 sessions was recounted and discussed in detail. Theoretical understandings drawn on to facilitate an understanding of the case were from Davis and Walbridge on Winnicolt, Winnicot, Liedloff, Kay, Romanyshyn, Bettelheim, Schwartz and others. , Thesis (MA) -- Faculty of Humanities, Psychology, 1993

- Description: The old city centre of Port Elizabeth, South Africa has undergone numerous changes throughout its lifespan and the recent changes have sought to reinvigorate and reinvent this old suburb to the bustling urban environment of yesteryear but unfortunately the state of central has continued to decline with the city continuing to expand towards the western periphery. Central has thus becomes a harbour for forgotten artefacts settled amongst what few activities remain as it sits as the foundation of the city. This document sees the exploration of a personal intrigue with what is considered forgotten and to this end the treatise is an investigation into heritage, and more specifically, the main writings and thoughts on memory and the physical environment and the core notions that contribute to its character. This treatise looks at identifying a set of lost and forgotten artefacts in the old city centre and a pragmatic response to solve the issue of single use buildings is put forward to develop strategies for the adaptive re-use within degraded urban heritage fabric to allow for the production of a catalytic precinct. The aim of this treatise is therefore to propose a building that is suitable for and responsive to its historical context, that meets the required developmental needs of the present but is ensured to meet the possible needs of future generations. This treatise aims to propose a relevant and appropriate artist colony in Central, Port Elizabeth. These aims are achieved through literature reviews, heritage practitioner comparative analyses, contextual analyses, and precedent studies in order to find an appropriate strategy for the design proposal. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2021

- Description: Energy security is critical to global economic development and agricultural activities. Electricity is one of the most beneficial types of energy for rural household livelihoods and smallholder producers in South Africa. This study aims to examine the effects of household agricultural income on the adoption of electrical appliances and energy security among agricultural households in Mnquma Local Municipality. The study employed primary data obtained from 224 households using simple random sampling technique across three electrification stages. Descriptive statistics, and binary logistic regression was used to determine the relationship between socio-economic and demographic characteristics of the household and the household agricultural income on the adoption of new electrical appliances and energy security across the three electrification stages. Descriptive statistics results indicated that non-electrified (67.1percent) and recently electrified (54.3percent) villages are dominated by female-headed households, while in electrified households there are more male head households (58.3percent). The results also show that among the households that have the highest total monthly income (greater than R15000), 34.5percent were electrified, 17.1 percent were recently electrified, and 4.3percent were non-electrified. The Binary logistic regression model's findings for the second objective revealed that household head factors such as age, monthly total household income, household size, and household agricultural income have significant effects on energy security. The study's findings revealed that household agricultural income has a significant impact at a 5 percent significant level on the adoption of electrical appliances. Binary logistic regression findings for the third objective revealed that on new electrical appliance adoption there was a significant effect of gender (at 5percent level), household size, energy security, and household agricultural income at a 1percent significance level. Binary logistic regression revealed that the coefficient of household size variable is positive and significant at a 1percent significant level on energy security and electrical appliance adoption. In this study, household agricultural income on the adoption of electrical appliances has been found to be the most critical factor influencing the energy security status of households among the selected rural households in Mnquma Local Municipality. As a result, policies must be put in place to facilitate access to electrical appliances through electrification programs, invention of affordable electric appliances, encourage participation in agricultural production and agricultural market access, that will provide households with social benefits. To improve energy security, electrical appliances should be simple to use and aid in the transition from biomass to electricity. , Thesis (MAgric) -- Faculty of Science and Agriculture, 2021

- Description: Mindfulness techniques can potentially facilitate increased self-awareness, improve impulse control, decrease emotional reactivity to challenging events, and improve one’s subjective experience of wellbeing. As yet, research within the child and adolescent population are in its early stages (Dellbridge, 2002. This study explores and describes the perceived wellbeing of adolescents participating in a Mindfulness-based adolescent programme. It uses a multiple case study format, within a qualitative paradigm. The sample of five adolescents are from the NGO, Masifunde, in the Eastern Cape, and were selected through a nonprobability purposive sampling. Participants were between the ages of 16 and 18 years. Data was collected using a pre-test post-test format, administering the Child and Adolescent Mindfulness Measure (CAMM), the Five Facet Mindfulness Questionnaire (FFMQ-15), and the Emotional Regulation Questionnaire for Children and Adolescents (ERQ-CA). After the Mindfulness-based Adolescent Programme (MBAP), individual semi-structured interviews were used to explore the adolescent’s perceived experience of the programme. Data was analysed using Braun and Clarke’s (2006) method of thematic analysis for qualitative data. The researchers reflective journaling was also used to expand on findings. Themes that emerged include the participants reflecting awareness of change in perceived experience of mindfulness, growing emotional awareness and regulation, development of attentional abilities, development of metacognition, reduction in physical discomfort, building and enhancing relationships, and experiencing body-based practices as most beneficial. The themes that came out most strongly were the reduction of physical discomfort, and positive experiences of body-based practices, which was understood by the researcher within the cultural heritage of participants. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: HIV and AIDS epidemic has caused much devastation and has left many children destitute and in need of care and supervision. The present study investigated the psychological experiences of caregivers caring for HIV infected orphans and vulnerable children (OVC). The context of working and living in orphanages is accepted as challenging for all concerned, yet the number of studies examining the challenging experiences of caregivers The study was informed by a qualitative research method and semi-structured interviews were used for data collection. The theoretical framework that informed this study is the Stress, Burnout and Coping Models. The study made use of a Interpretative Phenomenological approach to explore the lived experiences of ten caregivers who participated in the study. From the themes that were abstracted it was evident that caring for HIV infected OVC is emotionally, physically and mentally strenuous for the caregivers. It was better recommended that caregivers be given recognition for their challenging work and be included in the planning and development of programmes that affect their caregiving role. Furthermore, emotional, psycho-social, and income-generating skills support programmes including training and educational programmes should be implemented. This will alleviate the distress inherent to the caregiving role and to equip them with the necessary skills for handling the demands of their work. , Thesis (MSoc (Psy)) -- Faculty of Social Sciences and Humanities, 2013

- Description: Educational policy documents, which are intended to enlighten teachers about what they should teach and how they should assess learners, contain both language and knowledge. How this knowledge is construed through language may reveal the kind of teacher envisaged by the document, and the assumptions made regarding the dispositions of these educators. There is a plethora of research on the relationship between the Curriculum and Assessment Policy Statement for English First Additional Language in the Further Education and Training Phase (CAPS-EFAL) and its impact on the learner in the classroom, but little evidence of research related to how curriculum documents envisage the teacher, and linguistic research pertaining to CAPS-EFAL. This research aims to use linguistic analysis to discover how the teacher is envisaged in this document, while speaking to the broader subject of the relationship between teacher and curriculum policy. This study adopts a framework which inspects this language using Systemic Functional Linguistics to analyse language in relation to its functions in social contexts, and the instructional knowledge built in CAPS-EFAL through applying elements of Legitimation Code Theory, analysing processes of knowledge production and recontextualisation. An investigation of the language revealed assumptions that the envisaged teacher is one who is already highly trained in aspects of language teaching and classroom methodology and pedagogy. While the analysis also revealed a high level of guidance for the teacher, there was a strong focus on the knowledge within the curriculum, and several assumptions made regarding the teacher’s prior knowledge before encountering or utilising the document. The analysis also revealed that CAPS-EFAL acknowledges that the teacher requires a sound knowledge of technical terminology related to language teaching, as well as general classroom pedagogies and routines. In addition, the document assumes that the disposition of the teacher is one who can make decisions without the need for absolute confirmation or authority from curriculum documentation. Overall, the analysis revealed an élite code in terms of Specialization; CAPS-EFAL is therefore based on the legitimacy of both specialised knowledge and the disposition of the teacher. , Thesis (MA) -- Faculty of Humanities, Linguistics and Applied Language Studies, 2022

- Description: In this work, the rheological properties of alumina slurries milled to different particle sizes were investigated. Viscosity increases as the particle size decreases. When increasing amounts of calcium hydroxide, strontium hydroxide or barium hydroxide are added, the viscosity first goes down and then goes up. This can be explained in terms of changes in pH and changes in ionic strength impacting on the surface potential of the particles in suspension. Adding the same concentration of different cations results in different viscosities, with the order being (from high to low viscosity) Ba>Sr>Ca. Effects of partial dissolution of and structural changes to the alumina particles at high pH cannot be excluded. In order to better understanding the different effects, it was attempted to measure the zeta potential of the slurries at different pH values. This resulted in highly positive zeta potential values over the complete pH range, without the observationof an iso-electric point. This does not fit to the observed changes in rheology and contrasts withliterature data. One explanation would be that the measurement system used is unsuitable to yield correct zeta potential values for the materials under investigation. , Thesis (MSc) -- Faculty of Science, Department of Chemistry, 2021

- Description: The South African abalone, Haliotis midae, is a commercially important species of mollusc which contributes significantly to the value of the South African mariculture industry. One of the primary challenges experienced by abalone farmers is the consistent production of juvenile abalone (spat) in sufficient volumes to keep stocking farms and facilitate expansion of the industry. One of the key production bottlenecks of H. midae is achieving adequate levels of larval attachment and metamorphosis (settlement). The larvae of H. midae are settled on polycarbonate plates which have been pre-conditioned with biofilms in seawater which is pumped ashore onto farms. The seasonal variability in settlement success reported by hatchery managers in South Africa is hypothesised to be as a result of different diatom species compositions colonising the settlement plates at different times of the year, with settlement success being lowest during the winter months. The following study investigated whether the addition of conspecific mucous to biofilms could result in elevated settlement success, and whether there was potential for sterilisation of this mucous. A novel method of mucous application, spraying it onto the plates as opposed to pre-grazing, was tested in settlement assays and the trials revealed the following results: • The addition of H. midae mucous induced significantly more larvae to attach to settlement plates, when mucous was harvested around the spawning season. • Elevated attachment of larvae on mucous treated plates did not result in more post-larvae occupying the plates at the end of trials, and increased mortality is likely attributed to introduction of pathogens in conjunction with mucous. • No increase in the final proportion of settled larvae which had metamorphosed or the rate at which they metamorphosed was observed between mucous application treatments and biofilm only treatments. Subsequent trials assessed whether methods of mucous handling could reduce the biosecurity risk associated with mucous use, and so mucous was either UV irradiated or autoclaved. These trials revealed the following findings: • No difference in attachment was seen between any treatments, including the untreated mucous. This is contrary to the findings of our initial experiments and illustrates that the attachment-inducing properties within mucous may be seasonally expressed. ii • Numbers of observed larvae/post-larvae on plates applied with UV and autoclaved mucous where less stable than biofilms only, especially in the second trial, illustrating that mucous still presents a biosecurity risk even after undergoing these handling methods as it may act as a substrate on which pathogenic bacteria could colonise. , Thesis (MSc) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: Aim: Over the last few years, there has been a significant increase in mental health challenges in adolescents, specifically anxiety and depression. There has thus been concern around what could be causing this increase. The present study therefore aimed to examine the link between maternal attachment and adolescent anxiety. Methodology: The research was conducted using a qualitative systematic review as the methodological approach. The sample included ten academic journal articles. These articles were searched using Google Scholar and The University of Fort Hare’s library database search engine. Final articles were selected based on the systematic review process of ensuring that the articles matched the inclusion criteria, centred on the main research question and sub-questions. Findings and Results: At the end of the systematic review process, the final literature articles were analysed using thematic analysis, which identified, analysed, and reported emerging themes. The study revealed that secure attachment and sensitive parenting buffer and protect against the risk and onset of anxiety and adolescent internalizing behaviours. The thematic analysis findings identified emerging themes based on the data analysis, which include: ‘Sensitive parenting as a buffer’, ‘Quality attachment protects’, ‘Safe haven’, ‘Insecure attachment precedes emotion regulation difficulties’, ‘Insecure attachment is associated with anxiety’, ‘Social problems,’ and ‘Negative parental-control undermines attachment security’. Conclusion and recommendations: The extracts provided by the literature were able to successfully give sufficient information to meet all of my study’s research objectives. The findings revealed that very few articles spoke about interventions that can be applied to assist in the development of healthy maternal attachment. Therefore, it is recommended that research be conducted on attachment-based interventions and building restorative adolescent attachment bonds. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2022

- Description: Introduction: School going adolescents have been identified as a group that is at risk of obtaining insufficient sleep due to shortened and irregular sleep, all of which can affect the overall wellbeing of adolescents. While there has been extenstive research on adolescent sleep around the world, research in South Africa has been limited. Of the research performed in this context, most has been conducted in city or urban contexts, but there has been comparatively less research on sleep in adolescents from rural and township areas. Therefore, this study focused on characterising and comparing the sleep-wake behaviour of late adolescents from selected rural and township areas in Alice in the Eastern Cape of South Africa. Methods: An adapted version School Sleep Habits Survey (SSHS) was included in the study and assessed demographic, academic, sleep-wake behaviour, lifestyle, and behavioural information of adolescents from rural and township schools in and around Alice. The survey was distributed physically to all the learners from four co-educational rural and township schools. The responses to the survey were analysed with descriptive and non-parametric inferential statistics, as all data were not normally distributed. Results: A total of 123 learners completed the survey. All the participants were in Grade 12, aged 16 to 26 years (median =18, IQR= 18-19) from rural (n=28) and township (n=95) schools. Seventy-four female and 49 male learners participated in the study. Within the sample, there were also a group of participants who were not adolescents (n=22) whose age ranged between 20 and 26. Reported sleep during both the week and weekend (7hours) was lower than both the recommended duration for adolescents and their own self-reported sleep need of a median of 8 hours and 14 minutes. Bedtimes were significantly earlier on weekdays than weekends. The need to do homework and feeling sleepy were cited as the main reasons for going to sleep during the week and the weekends. Wake times on weekdays and weekends did not differ, with most learners citing being woken up by an alarm clock as the main reason for waking during both weekdays and weekends. Most learners (n=47; 38%) reported walking to get to school, while 41 (33%) relied on public transport to get to school. There were no significant effects of gender or of being rural and township scholars in relation to their sleep variables. Comparisons between non-adolescents and adolescents revealed that non-adolescents reported sleeping longer (7 hours and 30 minutes) compared to adolescents (7 hours) than adolescents did on weekends. As a group, the learners in this sample were morningness-orientated in terms of chronotype, presented with low day time sleepiness, some evidence of sleep-wake behaviour problems and of depressive mood symptoms. Nearly half (n=53; 43%) the group reported napping occasionally on school days. In terms of caffeine consumption, just over half (n=64; 52%) of the learners reported never consuming caffeinated substances such as soda, coffee, or tea. Conclusions: The reported sleep duration of learners in this study was consistent on both the week and weekend but was shorter than the recommended 8-10 hours for late adolescents. While learners in this sample reported early bedtimes, sleep was likely curtailed by the early rise times due to the contextual constraints where scholars had to commute, by either walking or taking public transport, to make the early school start times. There was a high prevalence of sleep disturbances in this sample however, the effects of this (increased daytime sleepiness) were lower which can be attributed to low reported prevalence of caffeine consumption combined with the high prevalence of reported day time napping on school days and weekends. While only a snapshot, the results of this study support previous research that has highlighted the challenges that many adolescents across the globe experience when it comes to obtaining enough sleep. The results of this study highlighted the need for more research to understand the sleep-wake behaviours of learners and their lifestyles more objectively. Given the early starts for many participants in this study, interventions such as delaying school start times may help to improve the amount of sleep that learners get during the week. However, extensive consultations would be needed to ensure that systemic changes that aim to improve sleep of adolescents are applicable for the context of rural and townships areas in South Africa. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2022
