  • Description: This study examined the implementation of Tourism curriculum in Secondary Schools in Fort Beaufort Education District in the Eastern Cape. The study arose from a concern that despite the Government of the Eastern Cape organizing workshops to facilitate the implementation of Tourism curriculum for secondary school teachers, research has shown that teachers have not improved their classroom practice. It discussed the concept of Tourism curriculum implementation and highlighted problems militating against curriculum implementation at secondary school level. The researcher adopted the mixed method methodology which is embedded in the post-positivist research paradigm. The post-positivist research paradigm explains the way things are and views objectivity as an ideal that can never be achieved, however research should be conducted with greater awareness of subjectivity. By combining qualitative and quantitative methodologies, it assisted the researcher to strike a balance and avoid being subjective on issues of teacher capacity, teaching strategies and assessment, availability and use of resources and support and monitoring. The research methods used in this study include questionnaires, interviews, document analysis and observations. The findings of the study showed that there are limitations in the implementation of Tourism curriculum because of lack of capacity of School management Teams and teachers who are implementing NCS Tourism. Although the teaching strategies and assessment are stipulated in the curriculum document teachers are not using appropriate methods and assessment. Moreover, there are crucial resources and facilities provided by SMTs and the Department of Education to implement Tourism curriculum, inadequate compared to those provided for other subjects. Moreover there are limitations in terms of support (including training) and monitoring systems which are in place to enable the implementation of NCS Tourism. Possible areas for future research were highlighted and recommendations were made, for example the researcher recommends teachers to be trained adequately in order to effectively implement the Tourism curriculum. Teachers should be encouraged to use new learner-centred teaching strategies and resources should be provided in all secondary schools through the combined effort of the government, Fort Beaufort Education district and the School Management Teams (SMTs). Support and monitoring systems should be in place for proper implementation of Tourism curriculum. Tourism industries should contribute through provision of instructional materials and teachers as implementers of the curriculum should be involved in decision-making and curriculum planning. The government should employ enough teachers qualified to teach Tourism. On the other hand subject advisors should be adequately trained to enable them to provide relevant support to teachers in Fort Beaufort secondary schools. All stakeholders should be involved in fostering skills and capacities at local level to develop sustainable Tourism and local development in an integrated way. The study identified a possible an alternative model for the implementation of Tourism curriculum. , Thesis (PhD) -- Faculty of Education, 2012

  • Description: Soil erosion by water is the major source of soil degradation in the world, and South Africa (SA) is not an exception particularly in the Free State (FS) Province. In South Africa, the Caledon River Catchment in the FS Province has been identified as one of the regions where soil erosion has been prevalent for decades. Evidence across many parts of the catchment show a widespread of soil erosion and the contaminant flux associated with sediment into river systems and reservoirs; including the Welbedatcht dam and Carthcart-drift dam in Ladybrand. It is of these issues that the current work aimed at enhancing the understanding of sediment sources and soil erosion dynamics at the Caledon River Basin. The objectives of the study were to locate sources of suspended sediments and to assess and quantify the contribution of Land Use Cover (LUC) classes to water erosion and sediment yield at a sub – catchment level of the Caledon River Basin. To achieve the objectives set out for this research, a study was conducted at a sub - catchment level of the Caledon River Basin in the FS Province, South Africa. The sediment–fingerprinting approach and the Revised Universal Soil Loss Equation (RUSLE) model were used in the study under Geographic Information System (GIS) settings. A qualitative and quantitative interpretation of the geochemical data were used to evaluate the potential for distinguishing catchment sediment sources. The application of multivariate sediment mixing models incorporating Monte Carlo simulations was undertaken to investigate recent variations in sediment sources. Lastly, to document the impact of LUC change on soil erosion; data from soil profile database, Landsat 8 OLI–TIRS and climate (i.e. rainfall) were used to assess and map the spatial and temporal pattern changes of soil erosion at a sub – catchment level as related to LUC changes. In this study, the sub–catchment was classified into 6 LUC classes. Thereafter soil erosion was quantified for three consecutive years namely; 2015, 2016 and 2018 using the soil erosion factors as GIS–layers. The investigation of sediment source types and spatial provenance in the catchment showed that the grassland areas have consistently been the main sediment source (83 percent) throughout the study period. Findings further showed that there was an increase in contributions from cultivation and abandoned cultivated fields. Sediment contribution from surface sources was dominant (54 percent) and thereafter, subsurface sediment input increased (62 percent). This trend is indicative of increased severity of gully erosion in the area and thus is consistent with other studies. To comprehend the influence of LUC class modification dynamics on soil erosion, water erosion in particular at the sub-catchment commencing from 2015 to 2018 (4 years), multi-temporal Landsat 8 information jointly with the RUSLE model were used. A post-classification, LUC class alteration comparison revealed that water bodies, shrubs and forested region and grassland declined by 0.27 percent, 15.60 percent, and 37.60 percent, respectively. On the other hand, regions under Bad lands, and bare-soil and built-up regions including agricultural region expanded by 2.22 percent, 5.78 percent, and 45.67 percent respectively, between 2015 to 2018 study period. The average yearly soil loss decreased at the sub-catchment and was 10.23,5.71 and 5.82 t ⋅ ha -1 ⋅ yr-1 for 2015, 2016 and 2018 respectively. Although soil loss lessened for the duration of the perceived period, a closer scrutiny revealed that there were nonetheless seeming signs of persistent escalation in soil loss risk. These signs were mostly shown in the elevated parts of the sub-catchment as shown by the red regions on the soil loss map. Additional examination of soil loss findings by LUC classes categories further indicated that most LUC classes categories, including Bare-soil and built-up area, agricultural-land, grassland, and region under shrubs and forests, showed increased soil loss levels during the 4 years’ study period at the sub-catchment. The information on the comparative vividness of diverse sediment sources given by the study must be observed as a noteworthy development towards an understanding of the sediment source dynamics in agricultural river based catchments; more so of the Caledon River Basin. Further research is recommended for other erosion prone catchments in South Africa to identify additional evidence of the spatial and temporal variations in soil erosion and sediment sources. The results of the study suggest that the procedure of assimilating the GIS and RS with the RUSLE model is not just precise, time-efficient and exact in recognizing soil erosion susceptible regions in geospatial and temporal standings. However, it is a cost-efficient substitute to standard field-founded approaches. , Thesis (MSc) (Soil Science) -- University of Fort Hare, 2021

  • Description: Orientation: Nutrition knowledge is an important aspect which shapes the lived experiences of women when they are making a purchase. South Africa, being a developing country, is faced with many challenges that have in turn subjected rural women to various challenges in approaching nutrition. These challenges include but are not limited to low economic status, low levels of education, and lack of developmental programmes that are structured to cater for rural women. Purpose: The purpose of this study was to understand the experiences and the perceptions of rural women concerning nutrition knowledge. Motivation for the study: This study was conducted with a motivation to understand how a sample of women in a rural area approach issues of nutrition. In understanding this, women can be empowered in asserting the approach to consumer behaviour. Research design: A phenomenological philosophy was adopted using a qualitative tradition in pursuit of the research objective. A judgemental sampling technique was utilised to sample 20 women and semi-structured interviews were undertaken and the gathered data on the experiences and perceptions of women was analysed by way of narrative analysis. , Thesis (MCom) -- Faculty of Management and Commerce, 2021

  • Description: For the past decades, technical efficiency and service effectiveness have become topical as performance measures in various sectors. However, a comparison of technical efficiency and service effectiveness for freight rail transport has received less attention in African and European countries. To address this challenge the current study seeks to analyse technical efficiency and service effectiveness of rail freight in African and European countries. Due to data unavailability in other countries, this study selected four African countries (South Africa, Morocco, Democratic Republic of Congo and Algeria) and four European countries (Lithuania, Austria, France and Germany). The data has been collected from the World Bank, International Union of Railway Statistics and Knoema for the period 2017. Input oriented and output oriented data envelope analysis (DEA) were used to analyze technical efficiency and service effectiveness, respectively. The application of DEA requires the selection of appropriate inputs, production and output variables. This study selected a number of employees and length of rail lines as input variables, gross train tonne kilometres (km) as production variable, tonnes carried and tonne kilometres (km) as output variables. The result shows that five out of eight countries were technical efficient and their services effective with values equal to 1.00. The Pearson correlation coefficient was used to analyse the relationship between technical efficiency and service effectiveness. The results indicate that there is a statistically significant positive correlation between technical efficiency and service effectiveness. To determine the impact exogenous variables on technical efficiency and service effectiveness, a Tobit regression analysis was conducted. The results show that technical efficiency and service effectiveness are not significantly affected by exogenous variables. On the other hand, technical efficiency is significantly affected by the number of employees while service effectiveness is significantly affected by gross train tonne km. This study recommends the use of less labour intensive assets and monitoring of gross train tonne km should be viewed as important strategies to improve technical efficiency and service effectiveness, respectively. , Thesis (MCom) -- Faculty of Management and Commerce, 2021

  • Description: In South Africa different species, from the genus Crataegus, including Crataegus monogyna Jacq and C. mexicana DC have been introduced for various reasons in the past. Populations of these plants have now established in multiple provinces. However, the invasive status, risk and insect pollinators that promote their reproduction and dispersal have never been studied in South Africa. This study was aimed at 1) Assessing the risk of, and mapping two Crataegus species, Crataegus monogyna Jacq and C. mexicana DC in South Africa, 2) Determining the role and effectiveness of insects pollinators to fruiting of C. monogyna and C. mexicana, 3) Identifying flower visitors of C. monogyna and C. mexicana, and 4) documenting potential dispersal vectors for both species in the Eastern Cape Province. A framework entitled “Framework and guideline for conducting risk analysis under NEM: BA Alien and Invasive Species Regulation of 2014” was used to assess the risk of the two Crataegus spp, and we conducted field trips to various provinces in SA to map their distribution. The author conducted an exclusion experiment to determine the role and effectiveness of insect pollinators. Observations were conducted to identify flower visitors and potential dispersal vectors for both species. The risk analysis results suggested that both species pose a high risk of becoming invasive in South Africa. The eradication feasibility of both species was found to be medium with C. monogyna having an eradication feasibility score of 5 and C. mexicana having an eradication feasibility score of 4. This meant that there was a 50 percent chance for both species to be eradicated in South Africa currently. After a thorough risk analysis, it was recommended that both species be listed under category 1b on the National Environmental Management Biodiversity Act. Category 1b species are invasive species that need to be controlled, and if possible, they must be eradicated, trading of species from this category is not allowed. Crataegus mexicana was found to be widespread in South Africa with ten relatively small populations distributed in 5 provinces; Limpopo, Mpumalanga, KwaZulu-Natal, Free State and Eastern Cape Province. Crataegus monogyna was found not to be widespread in South Africa, with only three populations found in the Eastern Cape Province. Insect pollinators contribute to the fruiting of both species in SA. However, the exotic plants were also observed to be able to self-pollinate when insects are excluded. Flowers of C. monogyna were visited by various insect species from orders Lepidoptera, Hymenoptera, Coleoptera and Diptera, while C. mexicana is visited by species from the order Hymenoptera, Diptera, Lepidoptera and Coleoptera. Seventy-seven percent (77 percent) of potential dispersal vectors observed for C. monogyna were birds, and 15 percent were mammals. For C. mexicana, 71 percent of potential dispersal vectors observed were mammals, and 29 percent were birds. Crataegus monogyna and C. mexicana are emerging invasive alien species in South Africa, and not much is known about them. Although the two species are listed as invasive weeds in South Africa, very little is known about their invasive status in other parts of the world. This study has managed to give baseline information and data about both species which are already in South Africa. The baseline information and data include the population structure of both species, their distribution, the risk they pose to South Africa biodiversity and their reproduction ecology. Currently, there are no management plans in place for both species in South Africa, and this is because they are not listed yet in the National Environmental Management Biodiversity Act of South Africa. However, this study recommends that current populations continue to be monitored, awareness of both species in various provinces be initiated to help in the discovery of new and emerging populations, and management options of large populations developed in the future. , Thesis (MSc) (Entomology) -- University of Fort Hare, 2021

  • Description: This mini dissertation investigates civil protests and their impact on human rights in the Republic of South Africa. South Africa is a democratic country that subscribes to representative democracy. Its civilians vote for political parties that elect members to represent them in parliament or in government. Civilians are not members of armed forces, such as police, soldiers, or fire fighters. These people are ordinary citizen with no power or authority to engage in war as they do not have arms or gear to do so. Whenever they feel aggrieved with situation or action by authorities (political leaders, government, or employers), they embark on protest to voice their grievances or disapproval. However, in the process of protest there have been developments of intimidation, vandalism, abuse, and violation of other people's rights. This happens even though the right to protest is enshrined to the Constitution of the Republic of South Africa. Section 17 of the constitution guarantees civilians the right to protest. It further stipulates the way in which protests should be conducted. The fact that protest is recognised as a right, means it plays an important role in assisting civilians expressing dissatisfaction with current situations and assert demands for social, political, and economic change. Additionally, the right to protest gives citizens right to participate in discourse. It is the individual and/or collective exercise of existing and universally recognised human rights that affords civilians opportunity to demand dignity, freedom of association and expression from authorities. Although this right is fundamental, it has its limitations, and its impact is crucial to human rights. This is so because every protest is human right inclined. Hence, this mini dissertation attempts to contribute to academic discourse by bringing forth human rights perspective on the impact of civil protest. The discourse has been majorly influenced by the following disciplines: sociology, social psychology, anthropology, political science, economics, and public administration. The existence of this study attempts to conscientize civilians about the importance of respecting, supporting, and protecting human rights. The study found that violent protests have negative impact on human rights. The negative impact is not only experienced by non-protesting civilians, but by protesting civilians. Because of the interdependency of rights, the study has also found that infringement of one right can lead to the violation of other rights. For instance, the burning of infrastructure such as clinic does not violate the right to access health only, but also violate the right to life, education, and security. Therefore, the study concludes that civilian's use of violence during protest action does not advance section 17 of the Constitution. Instead, it violates the same section or right. Moreover, negative impact of violent protests cost civilians dearly. Because after destroying property, the same civilians that destroy property are the ones who suffers. For instance, burning of police vehicles, makes it difficult for police to attend civilian's calls for help. Lastly, this mini dissertation concludes by recommending areas where government and civilians need to consider in respecting, supporting, and protecting human rights in a protest. , Thesis (MPhil) -- Faculty of Law, 2021

  • Description: Small, micro and medium-scale enterprises (SMMEs) contribute significantly to economic growth, employment and boosting the livelihoods of the poor in Zimbabwe. In the context of the Fast-track Land Reform and Re-distribution programme, agricultural SMMEs are viewed as the main pillar that anchors the recovery of the agricultural sector. Despite the key role they play, these SMMEs operate in a financially constrained environment in which access to funding is limited. In such a context, the ability of the SMMEs to perform their role depends on the strategic use of limited funding. One way to achieve this is to ensure that the funding used at each of the life-cycle stages of the business is the most suitable in addressing the main threats to business success. Much has been studied about how the supply-side factors have constrained growth and development. However, very limited focus has been placed on how SMME owners use the limited funding secured to address the main operational problems faced. The funding behaviour of the owners has to support the supply-side initiatives if the SMMEs are to survive and fulfil their envisaged role in the economy. This study thus analyses the use of funding by the owners along the business life-cycle based on a six-stage life-cycle model. It further analyses the suitability of such funding given the unique operational needs and challenges per stage as well as best practices. The specific objectives of the study are to identify the level of knowledge that SMME owners have about the financing options available and which ones are mostly used, determine the use and suitability of life-cycle financing focusing on agricultural SMMEs and also determine the most suitable life-cycle funding in terms of best practices for sector development. A cross-sectional survey research design was used given the lack of accurate time-series data and it followed a mixed-methods approach. Quantitative and qualitative data were analysed. The owners or managers of agricultural SMMEs and the institutions providing funding constituted the two populations studied. A multiple-stage sampling strategy was used to determine a final sample of 320 owners of agricultural SMMEs while purposive sampling was used to draw a sample of 12 main SMME financing institutions. A semi-structured questionnaire was used to collect data from the owners while an administered semi- structured questionnaire was used for financing institutions. The unit of analysis was the funding used along the business life-cycle. Frequency, binary logistic regression, Chi-Square tests of association and Odds-ratio analysis were used for quantitative data analysis while Qualitative-failure mode, effects and criticality analysis (Q-FMECA) and thematic analysis were used to analyse qualitative data. Results show a persistent rather than transitory reliance on internal funding contrary to theoretical propositions on life-cycle financing. Overall, life-cycle funding used was not in line with best practices for funding SMMEs especially in financially constrained environments where funding should be effectively and efficiently used. The study adds to literature on agricultural SMMEs funding in financially constrained environments and makes offers some policy recommendations to improve financing for development of the key subsector. , Thesis (DPhil) -- Faculty of Management and Commerce, 2021

  • Description: The purpose of the study was to assess multi-grade classroom teaching strategies in rural primary schools at Amatole East Education District. The lens with which to view pedagogical practices of multi-grade teaching was through Bronfenbrenner Ecological System on Human Development and Vygotsky’s Social Learning Theory. An interpretivist paradigm within a qualitative research approach was chosen as befitting the study. The study sampled four primary schools in Amathole East Education District, with eight participants purposively selected. Data collection methods included semi-structured interviews, classroom observations and documents. Data gathering instruments utilised were Interview Schedule, Observation Sheets and Document Checklist. Data was analysed and interpreted through thematic and content analysis. Peer tutoring, self-directed learning and group-work were found to be the most effective teaching strategies in classroom-based teaching. Instructional techniques that involved teacher–directed activities and learner-directed learning activities were viewed as most beneficial for learners in multi-grade settings. However, multi-grade teachers struggled in coping with the utilisation of time and resources in teaching learners of different grade levels combined in the same classroom. The study concludes that during separate grade teaching, grade-by-grade approach, thematic teaching or individual seatwork utilisation of differentiated tasks accommodate application of a variety of teaching strategies. Thus the study suggests that pedagogical practices can be differentiated to address learners’ diverse learning needs, paying more attention to struggling learners. It is further recommended that teachers in multi-grade situations be equipped with special multi-grade teacher training through in-service training programs to overcome challenges of teaching in multi-grade settings. , Thesis (MEd) -- Faculty of Education, 2021

  • Description: Scavenging chicken production plays a significant role in the lives of rural farmers as it ensures food security by providing eggs and meat to rural farmers almost in all developing nations. Rural farmers not only consume scavenging chickens, they also sell live chickens to customers to generate immediate income and are able to acquire other products using the money from the sales. The purpose of this study was to investigate production performance, socioeconomic benefits, and agricultural extension services support for scavenging chicken producers. The study was carried out in eight villages in Raymond Mhlaba Local Municipality in the Eastern Cape Province of South Africa. This study employed the multistage sampling technique for data collection from respondents between October and November 2018. The study used descriptive statistics, frequencies, percentages and multiple linear regression models to analyse quantitative data that was collected from a survey of 161 rural farmers that rear scavenging chickens. The results reveal that the majority (68.3percent) of the respondents in Raymond Mhlaba Local Municipality were women, while 52percent were married. Forty-eight percent of the respondents had attained high school education. The majority (53.4percent) relied on social grants and a further majority (68.3percent) had 1 to 10 years of experience in scavenging chicken production. The majority (84.5percent) of the households had between 1 and 50 chickens, with an overwhelming majority (95percent) practising free range system. Most (74.5percent) of the chicken houses were built with scrap material found within the community. The supplementary feed that was mostly offered to scavenging chickens was maize. The majority (95.7percent) of respondents experienced disease outbreaks, the most dominant of which was the Newcastle disease. Most (94.4percent) of the farmers offered a variety of indigenous medicines, mainly Aloe Ferrox. In addition, the majority (88.8percent) of the respondents experienced predation challenges The primary purpose of rearing scavenging chickens was consumption. Chickens were slaughtered for home consumption while forty-two percent at most. Most (50.9percent) of the respondents indicated that they offered chickens as gifts and as friendly gestures. The majority (82.0percent) indicated that they did not use chicken for any cultural rituals. A large (88.2percent) number of the respondents felt food secured as a result of rearing scavenging chickens, as they access products such as eggs and meat. The majority (98.8percent) of the respondents had never received any form of training from agricultural extension services. The results of the multiple linear regression model revealed that independent variables such as number of chickens, type of cockerels, number of hens, type of housing, type of training and cost of trainings had strong statistical significant values (p<0.001) zero-order correlation with production performance,while age and gender had statistical significant values at (p<0.05) and (p<0.010). For the improvement of the production performance of scavenging chicken production of rural farmers, the study recommends massive campaign among the farmers by agricultural extension services to create awareness on the dangers inherent in the use of unorthodox approaches to treating pests and diseases in scavenging chicken. Scavenging chicken farmers could be supported with simple technologies that are affordable on housing, medication and feed supplements. Training should focus on housing, disease management and feeding of scavenging chickens. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

  • Description: This study seeks to interrogate the presentation of women in selected South African texts written by a male and female South African author, whose central thematic thrust is the role of women in their day-to-day struggles during the apartheid era. An in-depth analysis of the texts enables this dissertation to provide a comparative study of the representation of women in both texts. The study also examines the kinds of fictional representations that are found in the texts and their significance in the emancipation journey of women from the supremacy of apartheid and customary laws. This study is informed by African feminism, focusing on the stance of Obioma Nnaemeka and Molara Ogundipe-Leslie. African feminism is chosen as a framework for exploring the texts because it is a theory shaped by the resistance of African women against Western rule. The theory embraces debates about motherhood and the contestation about the roles of motherhood in a society. The theory ponders how motherhood is a source of empowerment, liberation and achievement in African societies. The theory affirms that women should equip themselves for effective resistance and participation in societal transformation. These two theorists are relevant because they are both committed to a critical investigation that seeks to differentiate present social conditions and their historical development. Their research examines the conceptualization of frameworks aimed at a social and cultural change grounded on the local and everyday experiences of women. The first chapter provides a broad overview of the study. This chapter highlights the significance of the study in terms of what it can contribute to scholarship on the representation of women in South African texts that reflect on the apartheid era, by analysing them through the lens of African feminism. The second chapter provides context to the critical reception of both novels, which outlines the focus of the research. This chapter also provides the theoretical framework, which provides an overview of the relevant theory on African Feminism that informs the study and highlights Nnaemeka and Ogundipe-Leslie’s concepts of ‘Nego-Feminism’ and ‘Stiwanism’. The third chapter focuses on analysing the portrayal of women in the texts, examining their interactions with one another, with men, and the subjugation they endure because of living in a patriarchal society. The fourth chapter provides a comparative study of the texts. Finally, the last chapter provides a conclusion, analysing the research findings. The study thus brings to the fore the similarities and differences in the representation of women in South African texts that were written in different decades by a male and female writer, that are nevertheless highlighting the same issues. Secondly, in exploring how women in the texts challenge the status quo, this research will hopefully expose how women are not constantly compliant and embracing marginalization as some texts present them but can be seen as having emancipative agency. The study, in particular, provides an analysis of the representation of women in the two novels, specifically, intending to compare and contrast the modalities of their representation in these works. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2021

  • Description: The main aim of this thesis is to provide a literary study through a comparative analysis of how sexual politics are played out in the texts Mating Birds by Lewis Nkosi and Hate No More by Arthur Maimane. It seeks to determine the modalities of representation of rape in each text and also to investigate the extent to which the novels are similar or different in the way in which they represent sexual politics or the politics of rape during the apartheid era. This investigation was done using Frantz Fanon‟s postcolonial theory and, particularly, his seminal work, Black Skin, White Masks. Most importantly, for the purpose of this study, is Fanon‟s chapter on the love/sexual relationships between the man of colour and the white woman. This is helpful as Fanon touches on what he believes the attraction of the man of colour to the white woman stems from. Using Fanon‟s theory, one discovers that the motivation for Ndi Sibiya to allegedly rape Veronica stems from his anger at the system of apartheid and its oppression of black people. This is similar to Philip Mokone‟s case; the novel explicitly states that he was motivated by anger and his rape of Jean Ryan was a form of communication to the white people and the apartheid system. , Thesis (MA) (English) -- University of Fort Hare, 2021

  • Description: Sexual Reproductive Health (SRH) is a significant aspect of adolescent’s growth. Adolescents particularly girls face the risk of exposure to Human Immunodeficiency Virus (HIV), Sexually Transmitted Diseases (STDs), child marriages, high rates of unwanted pregnancy and the risk of those pregnancies can lead to unsafe abortion. In South Africa, considerable progress has been made in achieving improved access to Sexual Reproductive Health and Rights (SRHR) among the general population, however, some factors influencing SRHR of adolescents and young people have been slow to achieve. The study aims to investigate factors influencing Sexual Reproductive Health and Rights of adolescents in Alice, which is located in the Eastern Cape Province of South Africa. The Social-Ecological Model was considered appropriate for this study as it provides a comprehensive understanding of the multiple and interacting determinants of Sexual Reproductive Health and Rights. A qualitative methodology was adopted, involving focus groups with high school learners, in-depth interviews with institutional actors (Department of Health, Basic Education and Social Development), and participant observations. The study reveals that adolescents’ have access to Sexual Reproductive Health services from healthcare centres but only a few utilize or access them due to barriers such as the geographical location, denial and judgement about young people's sexuality limits their access to comprehensive knowledge to protect and promote their Sexual and Reproductive Health. The findings show that the adolescents who were most affected by Sexual Reproductive Health and Rights challenges were those from deep rural areas. They had minimal information/education compared to those residing in areas close to the town of Alice and major roads. Multi-sectoral interventions empowering adolescents and young people to exercise their rights to optimize SRHR service yield better results. , Thesis (MSc) -- Faculty of Science & Agriculture, 2021

  • Description: The ‘Fees Must Fall’ movement which occured in 2015 and 2016 was a major national event which affected most higher education institutions in South Africa. This research considers the constructions of the ‘Fees Must Fall’ movement at an historically black university, namely, the University of Fort Hare. Furthermore, the research analyzes how students are positioned in their constructions in relation to the movement. The study aims to contribute to the understanding of the lived experiences of student activists in the 2015 and 2016 ‘Fees Must Fall’ movement at the University of Fort Hare. The data collection method used was a convenience sampling method with seven participants interviewed. Making use of the guidelines of a Foucauldian Discourse Analysis, four primary discourses were identified from the data collected: coercion discourses; fear discourses; financial discourses; and meritocracy discourses. The positions of students were varied and consisted of both agentic and submissive positions, with the student representative council frequently being positioned dominantly. The theoretical framework also included Michel Foucault’s theories of governmentality and biopower which contributed significantly to the understandings of institutional power in the university context. The research is conducted against ethical backdrop of the philosophies and guidelines of postcolonial psychology. The broader context of South Africa is observed and discussed, specifically recognizing the legacy of apartheid and other historical antecedents such as colonization. The issues of transformation, institutional racism, and decolonization are placed at the forefront of this research endeavour. , Thesis (MSoc Sci) (Psychology) - - University of Fort Hare, 2021

  • Description: This study focuses on the East London Industrial Development Zone (ELIDZ) in South Africa. The ELIDZ strategy came as a response to the need for a robust catalyst for sustainable regional economic development, industrial diversification and to create meaningful employment opportunities in the country. It was supposed to provide customised solutions for various industries including automotive, agro-processing and aqua-culture. However, an Industrial Development Zone should promote innovati on and entrepreneurship to stimulate economic growth and global competitiveness. Economic stagnation, joblessness and inequality continue to be a reality for the previously marginalised groups after 16 years of the ELIDZ despite significant investments in the automotive sector, the growth of companies that supply Mercedes Benz with parts and the establishment and growth of innovative start-up companies at the ELIDZ Science and Technology Park (STP). Massive joblessness, poverty and economic stagnation had followed the collapse of the old industrial parks. The ELIDZ strategy of industrial development came as a response to the demise of the old parks and was meant to become the main vehicle for job creation, local innovation and global competitiveness. This study therefore investigated the extent to which innovation and entrepreneurship have fared in driving sustainable local economic development and how they have impacted jobs at the ELIDZ and within the East London community. The study was qualitative in nature and employed the non-probability sampling technique. In-depth semi-structured interviews were conducted with key informants that included Industrialists, Business Executives that were tenants at the ELIDZ, the Buffalo City Municipal Metro and community members with knowledge of and association with the ELIDZ. This was augmented by desktop and observational data. It was found that innovation and entrepreneurship was still a fairly new phenomenon at the ELIDZ and their flagships had the vision but were not yet driving sustainable local economic development to a large extent. The model lacks adequate diversification as most of the innovation projects are in the renewable energy and information communication spaces. Very few have made it to mass production with downstream industry employment creation for plumbers, artisans and marketers involved in the supply, distribution, instalment and maintenance of the Hotspot and Thin-film solar panels. New industrialists like YEKANI Technologies and Manufacturing and KGI Holdings, already employ some people and have the vision to employ thousands more of young people. The main innovation and entrepreneurship projects of the ELIDZ have had some impact at the grassroots level even though it is still limited. Too few jobs have been created compared to the old industrial parks model. The ELIDZ is therefore playing an important (albeit limited) role as a local employment creator, even though it has not revitalised the Eastern Cape manufacturing landscape. Due to its highly technology driven and specialised skills nature, the ELIDZ model is benefiting the few and therefore has not yet been an effective instrument to resolve the disturbing levels of inequality, poverty and unemployment, that underlie racial, class and gender dynamics in East London. The study concluded that innovation and entrepreneurship projects at the ELIDZ were contributing towards driving sustainable local economic development to some degree. However, due to its narrow industrial focus and highly technical and specialised skills driven business model, it excludes most historically disadvantaged communities and the local academic institutions need to do more to produce the skills relevant to support local innovation and local industrial development in a time when economies rely more on intellectual capabilities rather than natural resources. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

  • Description: Mob justice is a major issue that will continue to occur as long as criminal activities exist. In South Africa, mob justice has become a major challenge for the government, particularly the South African Police Service as well as the society at large. The South African Police Service (SAPS) has partnered with all relevant role-players in the fight against mob justice and other community problems which threaten the safety of inhabitants. However, concerted efforts have also been made by the government to assist the SAPS to address the occurrence and re-occurrence of mob justice by introducing strategies such as visible policing but the problem seems to persist. The study, thus, analyzed the challenges faced by the police that lead to their ineffectiveness in eliminating mob justice. This thesis draws from two theories, namely Structural Violence theory pioneered by Galtung (1969) and Just World Theory (JWT) by Adelstein (1999) to explore the challenges faced by the police in Gqeberha. This study was conducted in the Eastern Cape Province, in Gqeberha within four townships, namely Kwadwesi, Kwazakhele, Motherwell, and New Brighton. The findings gathered by utilizing Focus Group Interviews (FGIs) and semi-structured interviews with a total number of forty-eight (48) respondents comprising of sixteen (16) SAPS members, eight (08) Community Policing Forum (CPF) representatives, four (04) community leaders and twenty (20) community members. This is a qualitative research project in which participants were chosen using purposive sampling. Participants were chosen based on their knowledge and experiences relating to the phenomena being explored. The aim was to gain an in-depth understanding of the challenges encountered by the police in combating mob justice to discover some techniques to improve and strengthen the police service to make communities safer. To analyse the data thematic analysis was utilized. The results of the study indicate that an increase in mob justice in Gqeberha has been reported to be a result of the high rate of crime. However, the fact that people know they will not get arrested for participating in mob justice is one of the concerns that have led to an escalation in mob justice. The study demonstrates that in most incidents the community members have once witnessed in their respective areas, the victims were killed while few survived and in all those incidents only a few arrests were made and in those few arrests, no convictions were made. Based on this issue of arrests, results indicate that the SAPS members are confronting some difficulties in identifying and arresting the perpetrators of mob justice. The reluctance of community members to report mob justice cases and to provide information was found to be the main challenge faced by the police in combating mob justice in Motherwell Cluster precincts. These challenges have been reported to negatively affect police work performance. Further analysis revealed that CPF, community members and community leaders as part of stakeholders who are working together with SAPS are also facing some challenges in addressing this issue of mob justice. The results also indicate that mob justice does not only harm members of the community who are subjected to these occurrences, but also the police, the victims and the perpetrators themselves. Evidence-based techniques to help eradicate mob justice incidents were developed in response to this problem of mob justice. The participants suggested that the police must be provided with adequate manpower, more community patrols and vehicles. It is believed that if the police could act in time and arrest the suspected criminals, a large number of people would be rescued from being killed in mob justice. The respondents also indicated that the police must build good relations with the communities by being visible and transparent in communities. Furthermore, the SAPS participants alluded that when people are sentenced, a community engagement needs to be conducted before those people are released outside as parolees. Other respondents mentioned the issue of education, proposing that the Criminal Justice System (CJS) should frequently conduct awareness campaigns, imbizos and public meetings to teach and inform people about its operations. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

  • Description: Chicken feathers are by-products of poultry processing which are generated in large amount because of the global growing demand for poultry meats. They have high contents of crude proteins in the form of keratin which could be valorized into digestible products. Keratinases are classified as a specific collection of proteolytic enzymes that have the ability for the degradation of recalcitrant keratinous substrates. Isolation and characterization of these enzymes from various microbial producers are gaining prominence in recent years due to their industrial and biotechnological application potentials. For this research, the collection of soil samples was done as well as the isolation of bacteria and the screening for keratinolytic activity. 16S rDNA sequencing and phylogenetic analysis were used to identify the isolates with efficient chicken feathers degrading capacity. Optimum conditions for the fermentation prcocess was enhanced for the production of keratinase. The fermentation broth was also analysed for various amino acids of protein, and the biochemical properties of the enzymes were likewise determined. Twenty two (22) bacteria were isolated from the soil samples, and 18 out of the 22 isolates showed proteolytic activity on solid media with diameters of halo zone that ranged from 5 ± 0.71 mm for isolate coded as PSS-03 to 25 ± 1.41 mm for isolate coded as PSS-06. Intact chicken feathers were degraded by proteolytic bacterial isolates in variable degree that ranged from 24percent for PSS-10 and 81percent for DSS-02. Extracellular keratinase production recorded for the isolates ranged from 63.63 ± 4.14 U/mL for PSS-10 to 693.63 ± 62.99 U/mL for DSS-02. Based on 16S rDNA sequence and phylogenetic analysis, the 2 isolates with remarkable keratinolytic activity coded as DSS-02 and PSS-14 were identified as Chryseobacterium proteolyticum FGNn and Pseudomonas aeruginosa GNFx. C. proteolyticum showed the maximum keratinase production of 756.36 U/mL after 72 h of incubation at optimized fermentation conditions which involved initial medium pH (4), incubation temperature (30 oC), inoculum size (2percent; v/v), and chicken feathers (1.5percent; w/v). Similarly, P. aeruginosa optimally produced keratinase (1055.45 U/mL) after 96 h of incubation at optimized fermentation conditions that involved initial medium pH (7-8), incubation temperature (30 oC), inoculum size (5percent; v/v), and chicken feathers (2.5percent; w/v). Furthermore, feather hydrolysate from C. proteolyticum FGNn had relatively higher abundance (>1.5g/100g sample) of arginine (1.85), serine (1.63), glycine (1.9) and lysine (1.62); while P. aeruginosa GNFx feather hydrolysate showed high abundance of arginine, serine, aspartic acid, glutamic acid, glycine, alanine, valine, and leucine with respective concentration of 2.06, 1.67, 2.39, 3.05, 1.87, 1.73, 1.56 and 1.65 (g/100g sample). The results showed that keratinases from the two bacterial isolates were optimally active at pH 8, and temperature of 50 oC for FGNn keratinase and 50-60 oC for GNFx keratinase. The enzymes displayed remarkable pH stability. Keratinase from C. proteolyticum was catalytically inhibited by EDTA and 1,10-phenanthroline but not affected by PMSF; while P. aeruginosa keratinase was not significantly affected by those class of protease inhibitors. Adiitionally, FGNn keratinase demonstrated high residual activity of 90percent, 103percent, 101percent, 110percent, 130, and 105percent in the presence of DTT, hydrogen peroxides, acetonitrile, triton X-100, tween-80 and SDS, respectively. Similarly, catalytic efficiency of GNFx keratinase was promoted in the presence of hydrogen peroxides (119percent), triton X-100 (140percent), tween-80 (150percent) and SDS (147percent) compared to the control. Furthermore, the keratinases from the both bacterial isolates exhibited catalytic efficiency enhancement and remarkable structural stability in the presence of laundry detergents tested. The findings from the study suggest the application potentials of the isolates for the bioconversion of recalcitrant keratinous wastes into digestible and quality protein hydrolysates. The properties of these microbial keratinases indicate that they may be exploited for various biotechnological and industrial processes especially in the formulation of detergents. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

  • Description: Keratinous biomass contributes a significant proportion of agro-based wastes in the ecosystem with minimal potentials for valuable product recovery. The generation of huge quantities of chicken feather from poultry processing farms prompts the valorization attempt via diverse avenues. Chicken feathers are a rich source of valuable keratin, yet the overall value chain is rudimentary based on unsustainable recovery techniques involving corrosive chemicals and high energy input processes. Although attempts have been made to extract keratin using microbial techniques successfully, the pre-treatment stage remains dominated by chemical use. Chicken feathers are composed of approximately 91percent keratin, 1percent lipids, and 8percent water. Therefore, lipid removal is a critical step in the valorization process as they contribute to access hindrance of the keratinases and other sulfitolytic systems to keratin. Consequently, the study undertook to explore the environment for lipolytic bacteria capable of degrading chicken feathers' lipid components. Sediment samples were collected for bacteria isolation. The bacteria were evaluated for lipolytic activity, and the potent isolates were identified based on 16S rRNA gene sequencing. The fermentation conditions for the production of extracellular lipases were optimized, and the produced lipases were characterized. Lastly, chicken feather lipids were hydrolysed with lipolytic bacteria. Out of twenty bacteria isolated from the sediment samples, six isolates coded as ACT003, ACT004, ACT010, ACT013, ACT016, and ACT019 showed lipolytic activity on solid media with a respective diameter of 12 mm, 66 mm, 29 mm, 11 mm, 12 mm, and 10 mm. Based on 16S rRNA gene sequencing and phylogenetic analysis, the isolates coded as ACT004 and ACT010 were identified as Bacillus sp. TTs1 and Bacillus sp. TTs2; and the nucleotide sequences were submitted to GenBank (NCBI) with the accession numbers MW556206 and MW556207, respectively. Bacillus sp. TTs1 showed the maximum lipase production of 641.25 U/mL at 72 h, under optimized conditions that included initial pH (5), inoculum size (2percent, v/v), incubation temperature (45 oC), agitation speed (140 rpm), CaCl2 (0.01percent, w/v), yeast extract (1percent, w/v), and tween-80 (10percent, v/v). Similarly, the lipase production by Bacillus sp. TTs2 peaked at 96 h with enzyme activity of 618.8 U/mL in improved fermentation conditions consisting of initial pH (5), inoculum size (2-8percent, v/v), incubation temperature (25 oC), agitation speed (180 rpm), CaCl2 (0.01percent, w/v), yeast extract and peptone (1percent, w/v), and tween-80 (10percent, v/v). The evaluation of chicken feather concentrations on free fatty acid liberation showed that 6-8percent (w/v) chicken feather was adequate with free fatty acids contents of 0.58percent and 0.86percent for Bacillus sp. TTs1 and Bacillus sp. TTs2, respectively. Both isolates' lipases showed remarkable catalytic efficiency at pH and temperature of 7 and 40oC, respectively. The comparative analysis of residual lipids between pre-and post-fermentation indicated a 39.9 ± 7.8percent and 51.2 ± 20.2percent hydrolysis efficiency for Bacillus sp. TTs1 and Bacillus sp. TTs2, respectively. This study's findings indicated the lipolytic potentials of Bacillus spp. and suggest the possibility of a full bio-based approach for chicken feather lipid removal in the valorization of chicken feathers. , Thesis (MSc) -- Faculty of Science and Agriculture, 2021

  • Description: Promoting a clearer understanding of the role of schools in developing democratic dispositions among young citizens is a matter of importance across the world. This is because school is believed to be the best place where future free and democratic citizens can be prepared. Similarly, it is a place where young people are equipped with the necessary skills and knowledge that will assist them in deliberating democratically, developing a better understanding of political structures and economic and world history, and learning the relevant numeracy, literacy and critical thinking skills. Unfortunately, current teacher education programmes appear to represent potential stumbling blocks to schooling playing a greater role in educating the youth for democracy and democratic citizenship. This study explored two contradictory theoretical roles for mathematics teacher education programmes, in relation to power and control in education and society. The first is that, in reality, mathematics teacher education is essentially re-productive, in that its authoritarian relationship does not encourage confrontational discussion or critique, or challenge existing and dominant practices. The second is that, in a world where democracy is increasingly becoming a global phenomenon central to development, teacher education is (or should be) essentially democratic in nature. Thus, underpinned by the interpretivist paradigm, this study employed a qualitative research approach. It also utilised a case study design as a strategy for data collection, in order to explore how the mathematics teacher education programmes in South African universities prepare learners for democratic citizenship. As such, three universities in two provinces in South Africa participated in the study, and data were collected through interviews, observation and document reviews. At each institution, interviews were carried out with mathematics teacher educators and pre-service mathematics student teachers in their second to fourth year of study. Similarly, observations took place in different teaching sessions at each institution, and in different formats. Relevant documents were also reviewed for the study. The research findings revealed that the concepts of democracy and democratic citizenship are multifaceted. The participants’ understanding of these concepts was influenced by their individual expectations, as well as their social, political and economic environments, among many other factors. In addition, it was evident that mathematics teacher education programmes play a significant role in developing socially active citizens and democratic mathematics teachers. The research findings revealed, however, that contradictions exist between pedagogical approaches that are capable of developing democratic citizens, mathematics teacher educators’ ideal image of their practices within the classroom, and the participants’ conception of mathematics. As a result, no engagement occurs in social and critical pedagogy within mathematics education classrooms, to allow learners to view mathematics as a tool for confronting issues of justice and inequality in their community and the world at large. The research findings also revealed that the practices of the main structures which are tasked with the responsibility of promoting democratic practices within higher education institutions seem ineffective, as a result of favouritism and an autocratic approach to decision making. Based on the research findings, a recommendation is made that mathematics educators democratise their classrooms, in order to develop democratic citizens who are committed to democratic principles. Another recommendation is that, in their mathematics classrooms, educators use a problem-posing pedagogical approach which is capable of challenging power structures, thereby empowering learners as users of mathematics. This will not be possible without a professional development programme guiding mathematics teacher educators in establishing and managing their democratic classrooms. Similarly, it is recommended that student representative councils, as the structures that are best known for supporting democratic citizenship at universities, strive to follow the basic principles of democratic governance. Finally, the researcher concluded that mathematics education and the task of preparing mathematics student teachers for democratic citizenship are of the utmost importance, if South Africans are to cultivate and maintain a democracy that contributes to a culture which fundamentally supports democratic principles. , Thesis (PhD) -- Faculty of Education, 2021

  • Description: This research was aimed at preparing carbon dots using the microwave method as a bottomup synthetic approach. The prepared carbon dots were them to be used as an electrode modifier in electrochemical detection of metal ion. The structure of the carbon dots prepared were characterized using different techniques including the FTIR, TEM, UV-Vis, PL, XRD and Raman Spectroscopy. It was observed that the nanoparticles consisted of carboxylic acid, amine and alcohol functional groups at their core and surface. UV-Vis and PL revealed that the carbon dots absorb more light in the visible and ultraviolet region, and the sizes of the carbon dots prepared were less than 10 nm. The carbon dots were then utilized for electrochemical sensing of Cd2+ ion, which is considered as one of harmful heavy metal ion when not controlled. Glassy carbon electrode modified with the carbon dots was utilized for the detection of Cd2+ through square wave voltammetry. Effect of different experimental parameters was studied which include electrode preparation, frequency, and amplitude. The electrochemical characterization of the electrode was done using the cyclic voltammetry and electrochemical impedance spectroscopy (EIS), the modified electrode was found conductive with much improved electrochemical performances. The obtained detection limit for Cd2+ sensing was 9.39 ppb, the developed C-dots modified GCE electrode was also tested with tap water Cd2+ spiked solution to demonstrate its implementation in real sample analysis. , Thesis (MA) -- Faculty of Science and Agriculture, 2021
