- Description: Photodynamic antimicrobial chemotherapy (PACT) is a well-known antimicrobial therapy technique used against multi-drug resistant pathogens. In this study, the syntheses, characterization, photophysicochemical properties, and the applications of symmetrically and asymmetrically substituted cationic indium (III) porphyrins linked to silver/copper ferrite core-shell (Ag/CuFe2O4) magnetic nanoparticles (MNPs) as potential photosensitizers for PACT are reported. The synthesized complexes include axially modified porphyrins quaternized through an axial ligand. All the asymmetrically substituted porphyrins were linked to the NPs via an ester bond and the symmetrically substituted porphyrins were linked (peripherally and /or axially) via self-assembly (Ag-S and/or Ag-N). The impact of axial modification, peripheral substituents, conjugation to the NPs, the number of positive charges, and the chain length of the alkyl halides quaternizing agents on PACT efficacy and photophysicochemical properties of porphyrins were studied. High singlet oxygen quantum yields and antimicrobial log reductions were observed. Lipophilicity and hydrophilicity of the porphyrins were also studies, where the complexes quaternized with methyl iodide showed relatively high hydrophilicity character. Upon in vitro PACT studies, the quaternized complexes were observed to have 0% viable colony, signifying their effectiveness. Moreover, the highest log reductions of 9.27 were observed against S. aureus and 9.58 were observed against E. coli. The findings from this work delineate that singlet oxygen generation alone is not a distinct factor on the PACT efficacy of the porphyrin complexes, since some of the complexes have practically the same singlet oxygen quantum but different PACT activity. However, other contributing factors including water solubility play a significant role. , Thesis (MSc) -- Faculty of Science, Department of Chemistry, 2021

- Description: This thesis presents the development of a regional ionospheric storm-time model which forms the foundation of an index to provide a quick view of the ionospheric storm effects over South African mid-latitude region. The model is based on the foF2 measurements from four South African ionosonde stations. The data coverage for the model development over Grahamstown (33.3◦S, 26.5◦E), Hermanus (34.42◦S, 19.22◦E), Louisvale (28.50◦S, 21.20◦E), and Madimbo (22.39◦S, 30.88◦E) is 1996-2016, 2009-2016, 2000-2016, and 2000-2016 respectively. Data from the Global Positioning System (GPS) and radio occultation (RO) technique were used during validation. As the measure of either positive or negative storm effect, the variation of the critical frequency of the F2 layer (foF2) from the monthly median values (denoted as _foF2) is modeled. The modeling of _foF2 is based on only storm time data with the criteria of Dst 6 -50 nT and Kp > 4. The modeling methods used in the study were artificial neural network (ANN), linear regression (LR) and polynomial functions. The approach taken was to first test the modeling techniques on a single station before expanding the study to cover the regional aspect. The single station modeling was developed based on ionosonde data over Grahamstown. The inputs for the model which related to seasonal variation, diurnal variation, geomagnetic activity and solar activity were considered. For the geomagnetic activity, three indices namely; the symmetric disturbance in the horizontal component of the Earth’s magnetic field (SYM − H), the Auroral Electrojet (AE) index and local geomagnetic index A, were included as inputs. The performance of a single station model revealed that, of the three geomagnetic indices, SYM − H index has the largest contribution of 41% and 54% based on ANN and LR techniques respectively. The average correlation coefficients (R) for both ANN and LR models was 0.8, when validated during the selected storms falling within the period of model development. When validated using storms that fall outside the period of model development, the model gave R values of 0.6 and 0.5 for ANN and LR respectively. In addition, the GPS total electron content (TEC) derived measurements were used to estimate foF2 data. This is because there are more GPS receivers than ionosonde locations and the utilisation of this data increases the spatial coverage of the regional model. The estimation of foF2 from GPS TEC was done at GPS-ionosonde co-locations using polynomial functions. The average R values of 0.69 and 0.65 were obtained between actual and derived _foF2 over the co-locations and other GPS stations respectively. Validation of GPS TEC derived foF2 with RO data over regions out of ionospheric pierce points coverage with respect to ionosonde locations gave R greater than 0.9 for the selected storm period of 4-8 August 2011. The regional storm-time model was then developed based on the ANN technique using the four South African ionosonde stations. The maximum and minimum R values of 0.6 and 0.5 were obtained over ionosonde and GPS locations respectively. This model forms the basis towards the regional ionospheric storm-time index. , Thesis (PhD) -- Faculty of Science, Physics and Electronics, 2021

- Description: Literature has revealed that indigenous learners, especially in many African nations are subjected to learning school science in unfamiliar contexts. Learners in Namibia where this study was conducted are no exception. In consequence, learners experience cognitive conflict between school science and the experiences learnt at home and in the community. This is exacerbated, in part, by the fact that science teachers do not seem to know how to integrate indigenous knowledge in their science teaching. As an attempt to address this problem, some scholars call for the integration of indigenous knowledge into the science curriculum to provide a much needed context for learning science. It is against this background that this study sought to use the indigenous technology of dyeing and weaving baskets as a cultural tool to mediate learning of chemical and physical changes. Underpinned by the interpretivist and Ubuntu paradigms, the study employed a qualitative case study research design. The study was conducted in the Zambezi region in Namibia. Four grade 8 Physical Science teachers, an expert community member, and a critical friend were involved as participants in this study. Data were gathered using semi-structured interviews, workshop discussions, participatory observation, and journal reflections. Vygotsky’s socio-cultural theory and Mavhunga and Rollnick’s topic specific pedagogical content knowledge were used as theoretical and analytical frameworks, respectively. A thematic approach to data analysis was employed to come up with sub-themes and themes. The findings of the study revealed that all the participating teachers in this study had never been exposed to ideas on how to integrate indigenous knowledge in their science teaching. As a result, they all embraced and valued the indigenous technology of dyeing and weaving as relevant and useful in the teaching and learning of chemical and physical changes. This study recommends that there is a need to empower science teachers on how to integrate indigenous knowledge in their science teaching in order to make science accessible and relevant to their learners’ lived worlds. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: The rationale of this treatise is to synthesize current research, nationally and internationally, both qualitative and quantitative with regards to methylphenidate and its use amongst university students. The study is undertaken to explore the use of methylphenidate by students, as well as the advantages and/or disadvantages of the substance as a performance-enhancer in tertiary institutions. The researcher chose a systematic review, because it summarizes the literature and it critically appraises and synthesizes a specific issue. It synthesizes the results of multiple primary studies that is related to each other, by using strategies that reduce biases and random errors. The methodology employed in this study is derived from Petticrew & Roberts (2006). They recommend that the proceeding 7-steps be noted and followed in conducting a systematic review namely: find existing reviews; define the research question; write the review protocol; decide on inclusion/exclusion criteria; source the literature; assess/appraise the literature; and write the report. The body of literature was accessed through the Nelson Mandela University’s Online Library Catalogue, specifically the accompanying databases: EBSCOhost, Digital Commons, Psych-info, Academic Search Complete, Sage Publications, Science Direct, JSTOR, and Taylor and Francis Online. This study, in the form of a systematic review, is undertaken to provide clarity and a broader perspective of the use of methylphenidate, the rationale or reasoning behind the use, as well as the negative consequences of non-prescription use of methylphenidate in universities, globally. The study is further undertaken to aid policy development in the construction of ethics concerning the use of methylphenidate in universities. Lastly, in relation to the analysis of data, the literature obtained from the systematic review was analysed using Braun and Clarke’s (2006) method of thematic analysis. Thematic analysis is a method for identifying, analysing, and reporting patterns (themes) within data (Braun and Clarke, 2006). Analysis will also be done by an independent reviewer to maintain rigour and reliability. , Thesis (MA) -- Faculty of Health Sciences, 2021

- Description: The knowledge base of the social sciences and helping professions is characterised by paradigms and theories that have stemmed from a Western intellectual perspective. This has produced many challenges; the main one being that the people of African origin unconsciously embrace the Western worldview leading to the marginalisation of their own view of the world which was a motivation for this study. A further motivation for the study emerged from the divorce rate in customary marriages that is higher than that of statutory marriage in the Makhoaseng Village (Elundini Local Municipality Integrated Development Plan Report, 2015-2016). Employing social constructionism as its theoretical framework, this study, which was located in a rural village in the Eastern Cape, sought to enhance understanding of the stressors and strengths of customary marriage, as well the value of indigenous marital counselling. This qualitative research study was guided by a narrative research design that involved the recruiting of a sample of twenty research participants through the nonprobability purpose sampling, with the local chief serving as a gatekeeper. The data were collected through two separate focus group interviews for males and females, respectively, each of whom were in customary marriages for a period of twenty years and more. As per cultural tradition, the focus group interview for females was conducted by a female colleague, whilst the researcher recorded the observations and the fieldwork notes. The thematic analysis generated four main themes around the participants’ perceptions and experiences of customary marriage, marital stressors, marital strengths and the value of indigenous counselling. The findings make a valuable contribution to the generation of guidelines for marriage counselling from an African worldview. , Thesis (MSW) -- Faculty of Health Sciences, 2020

- Description: This study was an appraisal of selected support services rendered by social workers to older persons in De Aar Service Area, Northern Cape Province in South Africa. The study endeavoured to achieve the following specific objectives: i) to appraise the nature and extent of the existing support services rendered by social workers to older persons; ii) to explore challenges experienced by older persons receiving support services from social workers; iii) to establish strategies that can be adopted by the Department of Social Development to restructure its interventions to enhance the services rendered to older persons; iv) and to assess measures that can be adopted by the service beneficiaries to ensure that they receive quality services. The study was premised on the theoretical lenses of sociology of weak ties (SWT) theory, Maslow’s Hierarchy of Needs model, and Social Exchange theory. The study was prompted by the growing number of elderly people who need the support services rendered by social workers as well as community based care. Methodologically, the study used a qualitative paradigm and was thus guided by the research design which was a case study complemented by explorative and descriptive study design types. The data was collected through in-depth one-on-one interviews, focus group discussions and key informants to strengthen the qualitative aspect of the study.

- Description: This study was an appraisal of selected support services rendered by social workers to older persons in De Aar Service Area, Northern Cape Province in South Africa. The study endeavoured to achieve the following specific objectives: i) to appraise the nature and extent of the existing support services rendered by social workers to older persons; ii) to explore challenges experienced by older persons receiving support services from social workers; iii) to establish strategies that can be adopted by the Department of Social Development to restructure its interventions to enhance the services rendered to older persons; iv) and to assess measures that can be adopted by the service beneficiaries to ensure that they receive quality services. The study was premised on the theoretical lenses of sociology of weak ties (SWT) theory, Maslow’s Hierarchy of Needs model, and Social Exchange theory. The study was prompted by the growing number of elderly people who need the support services rendered by social workers as well as community based care. Methodologically, the study used a qualitative paradigm and was thus guided by the research design which was a case study complemented by explorative and descriptive study design types. The data was collected through in-depth one-on-one interviews, focus group discussions and key informants to strengthen the qualitative aspect of the study. This current study used a probability sampling method, specifically a purposive sampling technique, to purposefully select a study sample that has all the characteristics needed to contribute immensely to the phenomenon under study.

- Description: Modern sports have made many claims, one of which is to give surety of equality within sporting codes. They also specifically focus on providing equal rights to allow individuals to compete in sports. The political history of South Africa is particularly important as it is essentially linked to the capacity to participate in sport in South Africa. Therefore, it is safe to say that politics and sports are intrinsically entwined in the country. Sport played a vibrant role in the struggle against the system of apartheid and has a vigorous role to play in the transformation and nation-building of South Africa. Islam has been open to growth and development, adaptation, and even change. Since its revelation, Islam has been filtered through a succession of cultural growth, reflecting the complex ways in which religious beliefs and social reality accommodate one another. Islam possesses a unifying framework which is provided by the Quran (Islam’s primary source regarded by Muslims as God’s revealed word) as the quintessential source along with the Hadith (the statements and deeds of Prophet Muhammad [Peace be unto him]) and language of the religion of Islam. This unity is accompanied by a multitude of diversities that must be considered in any discussion regarding Islam and its practice by Muslims. The Muslim women presented in this thesis were specifically from the Malabar area in Port Elizabeth, where different interpretations or perspectives of Islam exist. Malabar was created in 1961 under the Group Areas Act of 1950 in terms of which the Apartheid government forced people of different race categories to live separately. In a variety of societies and communities where legislation, customs, and traditions are affected or inspired by interpretations of the Quran and Sunnah, they combine to define the roles and status of men and women. Within a specific Muslim society, however, these may vary from one class or generation to another. Muslim women’s lives and the choices they face are influenced as much by patriarchal social arrangements as they are by religious ideology. The research is centred around the interpretations of Islam and what these interpretations mean for Muslim women and their participation in sports, while also considering the interconnectedness of personal choice and the rules and regulations of Islam. The objective of this study was to critically analyse the effect that the different interpretations of Islam have on Muslim women’s participation in sporting activities, as iii well as the barriers that Muslim women face during their involvement in sports. The research adopted a qualitative research method in which 20 Muslim women were interviewed, with the use of semi-structured interview schedules, as well as participant observation to collect the necessary data. A case study method was used to share the data collected from interviews. Furthermore, an auto-ethnographic method is also utilized for self-reflection and to explore personal experience relevant to this research. This thesis also draws on the Marxist feminist theoretical approach, focusing on investigating and explaining how women are oppressed through systems of capitalism and private property. Marxism and feminism are theories of power, which is distributed unequally in society. In researching gender, religion, and sport, I found that the relationship between Muslim women and sport is understood in different ways because of different interpretations of Islam and its teachings, often between one generation to the next and amongst various Muslim communities. Thus, individuals who are passionate about their sport will go the extra mile to ensure participation. In some cases, this would be regardless of the rules and regulations of Islam. Muslim women across the world have made many strides and overcome many barriers in sport. Over the years, although not favourably portrayed in the media, participation by women has increased drastically over time. This thesis explores gender, religion, and sport as well as the ‘lived body’ experiences of veiled Muslim women in sport and physical activity. I attempt to explain the relationship between religious requirements and participation in sport and physical activity. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: Everyday activities of communities are dependent on services provided by the local municipality, district or regional council and the national government. These activities range from water flowing freely from taps, a roof to hide under, and a clean and healthy environment, just to name a few. The Batho Pele principles were introduced to ensure that these services are provided for the benefit of the people. They were introduced to make sure that people are involved in the process of service delivery so that services are exactly what they need. It is important to note that the Batho Pele principles inform service standards and a customer care charter. This means that the government or providers of service listen to citizens’ views and take them into account when making decisions about service delivery. Informing service standards and a customer care charter also means that service providers or the government responds swiftly and sympathetically when the service standard falls below the promised standard. The problem occurs when citizens are not being consulted about the type of services they are entitled to. The citizens of Buffalo City Metropolitan Municipality had an issue with how services are provided. They stated that even though service delivery was improving, the manner in which these services were provided was not satisfactory. They complained that they were not asked about what they needed and what their priorities were. Moreover, they stated that when they complained, they did not receive an effective response. The main objective of this research was to establish citizens’ experience with consultation and redress as core functions of the Batho Pele Principles. Furthermore, this research sought to establish important elements of proper citizen consultation and redress in the literature, to determine the extent to which these principles are adopted in in BCMM, to establish the effects of current consultation and redress practice on citizens’ trust in their local government and to make recommendations on effective approaches to consultation and redress. The theories that guided the study are the agency theory, the social equity theory and the procedural justice as a derivative of social equity theory. The legislative framework includes the White Paper on Transforming Public Service Delivery (Notice No 1954 Of 1994), the Constitution of the Republic of South Africa, the Municipal Systems Act no 32 of 2000 and the Promotion of Administrative Justice Act 3 of 2000. The study used both the qualitative and quantitative methods. It also used a case study design. The study used a sample of 110 respondents and the data was collected using interviews, questionnaires and a focus group discussions. Analysis of data followed the narrative and descriptive paradigms. Most importantly, all the objectives of the study were met. , Thesis (MCom) -- Faculty of Management and Commerce, 2020

- Description: This thesis has engaged in a debate that the establishment of colonial administration in Buganda in the 19th century more than anything else saw the transformation the Buganda state into an African feudal state. Basic explanation for this state of affairs was the need by the colonial authority to establish a dependent commodity producing economy in Buganda. The African feudal state contextually referred to is the transformation of power, labour and economic relations in this period to suit circumstances that favoured the process of commodity production in the Buganda state; a process that involved the strengthening of the political power base, by creating a landed oligarchy, thus destroying the traditional patron–client relations and creating out of such a relation a class of civil servants, yet also extracting land rent from siting tenant in an agrarian economic system. This period saw an interplay of numerous actors like the Christian missionaries and their Buganda collaborators, the Christian elite (Abasomi), the Learners. The second phase of this study examines the creation of a colonial economic system based on commodity production and the colonial authority creating a frame work of operation, as to how the economy-based commodity production was to operate as to either allow a settler plantation or a peasant mode of production. Coupled with the effects of the wars of nations the deteriorating economic conditions and the age of the rise of the spirit of nationalism in the 1950s, created a class of agitators against the colonial authority. Using the historical methodology, the study employed the use of oral interviews, archives, primary printed journals, and secondary sources, to trace the evolution of labour, political and economic relations in the Buganda state. This was in order to understand the process leading to the creation of the modern Buganda colonial state by 1962. The study puts it that the intercourse between the British colonial administrators and the Buganda state leaders was responsible for the resultant state of affairs. Intentionally or unintentionally, the British colonial authority created a new nation state dominated by a landed class elite. It is this elite class that led the independence struggle not for the whole nation but for one region of the country - their kingdom Buganda - the cause of conflict between the British colonial authority and the Buganda Kingdom, but also a source of economic and political competition between Buganda and other regions of Uganda. , Thesis (PhD) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: In 1998, following a recommendation made by the United Nations Educational, Scientific and Cultural Organisation (UNESO), the Joint United Nations programme on HIV and AIDS (UNAIDS) adopted a cultural approach to HIV and AIDS prevention and treatment for sustainable development. Cultural identity, values and norms are all influential factors in health decision making and may be especially important in the context of HIV infection. The research aim of this study was to explore and describe the experiences of HIV positive Xhosa males in relation to understanding how cultural identity, cultural values and norms influence the health decision making behaviour of Xhosa males. A qualitative study design was adopted. A descriptive and interpretative approach was applied. Semi-structured interviews were conducted with 10 HIV positive Xhosa males aged 25 to 49 years in four primary healthcare clinics in the Nelson Mandela Bay. Thematic data analysis was utilised to analyse the data through the lens of literature and the bio-ecological model. The data was coded by the researcher and an independent coder. Three themes and six sub themes emerged from the study. Theme one is: significance of culture for HIV positive Xhosa males. Theme two is: perspectives on factors that have an influence on health decision making. Theme three is: perceived beliefs and perceptions about HIV and AIDS in the Xhosa ethnic group. The study indicated that cultural factors such as ancestral beliefs regarding illness, traditional circumcision, initiation school and masculine roles and expectations influenced health decision making of the Xhosa males. In addition, there are other factors that have an influence on health decision making such as psycho-social factors of peer pressure and biological factors which include physical developmental changes. In addition to factors that have an influence to health decision making, it became apparent in the study that there was perceived stigma attached to HIV and AIDS from family members and the Xhosa community. Participants also experienced internalised stigma and expressed a v fear of not having an heir; thus, influencing risk taking health decision in fear of being stigmatised. Perceptions of HIV positive Xhosa males on cultural factors that have an influence on health decision making such as risk behaviour and adherence to treatment are: ancestral belief of protection against illness, traditional circumcision, initiation school and masculine roles and expectations. , Thesis (MA) -- Faculty of Health Sciences, School of Behavioural Sciences, 2020

- Description: South Africa has experienced a high and rising burden of non-communicable diseases (NCDs) and lifestyle risk factors over the past decade. Health as a category of human capital is generally ex-pected to influence an individual’s labour supply and productivity. Despite the increasing burden of non-communicable diseases, the high rate of economically inactive population and persistent wage inequalities in South Africa, there is limited empirical research on the effect of NCDs on labour force participation, employment status and wage differentials. Given this, the main object-ive of this study was to determine the effects of NCDs on three labour market outcomes: labour force participation, employment status and wage differentials in South Africa. This was divided into three major analytical objectives. Data used was extracted from the five waves of the National Income Dynamics Study, a nationally representative survey collected by the South African Labour and Development Research Unit (SALDRU). Several econometric tests, including cross-sectional data analysis, panel data analysis and the Blinder-Oaxaca decomposition methods, were used in the study. The first analytical objective focused on estimating the effect of lifestyle risk factors on labour force participation through NCDs by gender. Endogenous multivariate probit models with a recur-sive simultaneous structure were employed as a method of analysis. The empirical findings suggested that NCDs and associated risk factors have detrimental effect on labour force participation. The analysis was further expanded to analyse the effect of gender differences, considering that the effect of NCDs may be gender-specific. The results revealed that the effect of stroke and heart diseases were significant only for men, while diabetes and high blood pressure were only significant for women. The results also emphasised the significant indirect influence of obesity, physical inactivity, and alcohol consumption on labour force participation through NCDs, especially for men. The second analytical chapter focused on investigating the effect of NCDs on employment status – that is, those employed, unemployed and economically inactive in the population of South Africa by gender. The estimation technique known as generalised linear latent and mixed methods (GLLAMM) was employed to fit the multinomial logit model with correlated random intercept. The findings suggest that NCDs affect the economically inactive population significantly relative to those employed, and the magnitude is larger for women than for men. There was no significant difference found in the effect of NCDs on the unemployed relative to the employed segment of the population. In addition, the results revealed gender differences on the effect of NCDs on employment status and that stroke had a significant influence on the employment status of both sexes, while heart diseases had significant influence only in men, whereas diabetes had significant effects only in women. The last analytical chapter focuses on estimating the effect of NCDs on wage differentials in South Africa by gender. The recentred influence function regression model and Blinder-Oaxaca de-composition with RIF were used in the chapter. The empirical results revealed that the effect of NCDs on earnings differ by gender. It was found that women with NCDs earn less than those without NCDs, while men with NCDs were found to earn more than their counterparts without NCDs. The results further revealed that women with NCDs suffer from wage discrimination in South Africa. The policy implications of this study are gender-specific. The results highlight the necessity for undertaking a massive awareness campaign regarding the prevention and control of NCDs, espe-cially among women. This can be achieved through specific female health programmes, including maternal healthcare. The findings of the study imply largely that calls for gender-responsive health approaches which take into account gender-specific needs and priorities should be promoted, compared to a blanket approach. In addition, there is a need for the government to complement education policies to promote labour market outcomes. Policies aimed at increasing access to education should continue to improve access to higher education and so to enhance participation in the labour force and reduce wage gaps. , Thesis (PhD) -- Faculty of Management and Commerce, 2020

The analysis was further expanded to analyse the effect of gender differences, considering that the effect of NCDs may be gender-specific. The results revealed that the effect of stroke and heart diseases were significant only for men, while diabetes and high blood pressure were only significant for women. The results also emphasised the significant indirect influence of obesity, physical inactivity, and alcohol consumption on labour force participation through NCDs, especially for men. The second analytical chapter focused on investigating the effect of NCDs on employment status – that is, those employed, unemployed and economically inactive in the population of South Africa by gender. The estimation technique known as generalised linear latent and mixed methods (GLLAMM) was employed to fit the multinomial logit model with correlated random intercept. The findings suggest that NCDs affect the economically inactive population significantly relative to those employed, and the magnitude is larger for women than for men. There was no significant difference found in the effect of NCDs on the unemployed relative to the employed segment of the population. In addition, the results revealed gender differences on the effect of NCDs on employment status and that stroke had a significant influence on the employment status of both sexes, while heart diseases had significant influence only in men, whereas diabetes had significant effects only in women. The last analytical chapter focuses on estimating the effect of NCDs on wage differentials in South Africa by gender. The recentred influence function regression model and Blinder-Oaxaca de-composition with RIF were used in the chapter. The empirical results revealed that the effect of NCDs on earnings differ by gender. It was found that women with NCDs earn less than those without NCDs, while men with NCDs were found to earn more than their counterparts without NCDs. The results further revealed that women with NCDs suffer from wage discrimination in South Africa. The policy implications of this study are gender-specific. The results highlight the necessity for undertaking a massive awareness campaign regarding the prevention and control of NCDs, espe-cially among women. This can be achieved through specific female health programmes, including maternal healthcare. The findings of the study imply largely that calls for gender-responsive health approaches which take into account gender-specific needs and priorities should be promoted, compared to a blanket approach. In addition, there is a need for the government to complement education policies to promote labour market outcomes. Policies aimed at increasing access to education should continue to improve access to higher education and so to enhance participation in the labour force and reduce wage gaps. , Thesis (PhD) -- Faculty of Management and Commerce, 2020

- Description: The democratic legitimacy of African executives has been called into question substantially over the last decade. Using the Democratic Republic of Congo (DRC) as a case study, this evaluative research seeks to analyse how African executives and political elites continue to play a crucial role in inducing civil unrest and electoral violence. For African democracy to develop, there must be enforced resolutions to eradicate issues facing both procedural and substantive democracy on the continent. This research examined electoral violence and unconstitutional acts that aggravate electoral system abuse and diminish the consolidation of democracy in sub-Saharan African states, in particular the DRC. A specific focus on the leadership of Joseph Kabila in the DRC forms the case study component of this research. In 2016, elections were postponed in the DRC and the DRC’s constitutional court interpreted Article 70 and Article 73 of the constitution in a manner that allowed President Kabila to remain in office until a newly elected president was installed. The court’s ruling and interpretation of Article 70 and Article 73 was an attempt to avoid a power vacuum. The study evaluated the components that trigger the escalation of electoral violence in Sub-Saharan African states. The study reports on different contributory factors, including but not limited to, the impact of predatory and rent-seeking leadership towards electoral manipulation; and the effect of patron-client relations on democratic institutions. Even though elections are not the only indicator of democracy stability in a state, this study demonstrated how electoral violence threatens the consolidation of democracy in sub-Saharan African states, in particular the DRC. In examining electoral violence, a desktop analysis method, which was used in the study, involved the collection of data from existing resources in order to provide a more critical lens to understanding electoral violence in the DRC. The theoretical analysis used in the study is the Höglund (2009) framework on electoral institutions which outlined how political violence remains a pervasive feature in Sub-Saharan countries by linking the framework to patron-clientelism. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: Heavy metal ions are elements that are discharged into water streams from municipal or industrial waste. In abundance, they can be threating to the environment and human health. Amongst other several convention methods, adsorption has been proven to be the most effective method in the removal of heavy metal ions from wastewater. The aim of this research was to fabricate electrospun polyacrylonitrile (PAN) nanofibers and modify their surface to improve the adsorption efficiency for Chromium and Cadmium metal ions from synthetic wastewater. Electrospun nanofibers PAN nanofibers were fabricated via electrospinning process though careful monitoring of its parameters and modified via two-step process: hydrolysis with sodium hydroxide (NaOH), hydrochloric acid (HCl) and ethylenediamine (EDA). The morphologies, functional groups, thermal stability, chemical composition and crystallinities or amorphous structures of the nanofibers were characterised by Scanning electron microscopy (SEM), Fourier-Transform Infrared spectroscopy (FTIR), Thermogravimetric analysis (TGA), Energy dispersive X-ray analysis (EDX) and X-ray diffraction (XRD), respectively. The experiments were conducted in batch tests to analyse the effect to pH, contact time and initial concentration of the solution. Ultraviolet-Visible spectroscopy (UV-Vis) was used to analyse the concentration of metal ions. The adsorption equilibrium was reached after 120 min with a maximum adsorption capacity of 301.1 mg/g for Cd(II) ions and 195.02 mg/g for Cr(VI) ions. The adsorption capacity increased with increasing pH and initial concentration of the solution. The adsorption capacity of Cd(II) and Cr(VI) ions was higher at pH 8 and 10, respectively. The equilibrium data was best described using Freundlich isotherm with a maximum adsorption capacity for Cd(II) ions than Cr(VI) ions. Pseudo-second order kinetic model best fitted both heavy metal ions with R2 value of 0.99 for Cr(VI) ions and 0.67 for Cd(II) ions. Heavy metal ions were desorbed from the nanofibers after one regeneration cycle with an equilibrium concentration of 4.83 mg/L for Cr(VI) ions and 43.06 mg/L for Cd(II) ions. , Thesis (MSc) (Chemistry) -- University of Fort Hare, 2021

- Description: This study was aimed at exploring the teaching and learning of Euclidean Geometry in five selected senior secondary schools in the O R Tambo Coastal District of the Eastern Cape, South Africa. The literature review was based on existing knowledge in the teaching and learning of Euclidean geometry. The study was built on analyzing the effective teaching strategies based on the teacher’s Pedagogical Content Knowledge (PCK) in Euclidean Geometry (EG). Shulman and Ma’s perspective on teachers’ competencies and knowledge of Mathematics was used as the theoretical framework of the study. A mixed-methods sequential explanatory design was adopted for the study. A purposive convenience sampling technique was used to select research sites and participants. The main instruments used were questionnaires, semi-structured interviews, classroom observation schedules, and document analysis. Quantitative data was analyzed descriptively utilizing tables and graphs. Qualitative data were analyzed using thematic data analysis. The various findings were interpreted through the literature and the theoretical framework. It was found that learners have a poor foundation in geometry and the methods teachers employed to teach Euclidean Geometry were inappropriate. Recommendations and suggestions were made. It is hoped that these recommendations would be noted by the appropriate stakeholders to ensure that improvement in the teaching and learning of Euclidean Geometry is achieved in our secondary schools to help matriculates’ obtain good marks in the final certification examination.

- Description: Coastal mangrove vegetation at Mngazana continues to be threatened and reduced periodically due to unmonitored harvesting. Covering an area of 148ha, the Mngazana mangrove forest remains unreserved, thus, research on the Mngazana mangroves is essential in order to monitor their state and sustainable management. Since in-situ monitoring of mangrove areas is both challenging and time-consuming, remote sensing technologies have been used to monitor these ecosystems. This study was carried out to monitor the impact of deforestation using ASTER satellite images over ten years: from 2008 - 2018. Validation was carried out by comparing classification results with the ground-referenced data, which yielded satisfactory agreement, with an overall accuracy of 94.64 percent and Kappa coefficient of 0.93 for 2008; and in 2009, the overall accuracy was 88.62 percent and a Kappa coefficient of 0.85. While the overall accuracy of 95.08 percent and a Kappa coefficient of 0.92 for 2016 and 2018 were observed, the overall accuracy of 93.58 percent and a Kappa coefficient of 0.91 was yielded. NDVI and SAVI indices were used as monitoring indicators. The results obtained in the study indicated that the canopy density of the mangrove forest remained unchanged in the years under investigation. However, insignificant changes in canopy density were identified between 2009 and 2016. , Thesis (MSc) (Applied Remote Sensing & GIS) -- University of Fort Hare, 2021

- Description: The Eastern Cape Provincial Government is comprised of 14 departments, including the Provincial Legislature, and ten (10) public entities. The legislative mandate of Eastern Cape Provincial Treasury (ECPT) is delegated by National Treasury to ensure transparency, accountability and sound financial controls in the management of public finances in accordance with the Constitution, PFMA and Treasury Regulations. The focus of the study is to investigate the perceived leadership style that exists at ECPT. Data was collected by means of a survey questionnaire which consisted of closed questions and distributed to a sample of employees at ECPT who hold positions for senior managers, middle managers and other employees outside these categories, such as administrative assistants. The following leadership styles were examined: Autocratic leadership style, Democratic leadership style, Laissez-faire leadership style and Transformational leadership style. The leadership styles were considered as dependent variables, including Intention to resign, while staff motivation was considered to be the dependent variable. Leadership is described as the social process of persuading people to work towards an institutional goal happily, enthusiastically and persistently. The results of the study revealed autocratic leadership was perceived as the most dominant style that exists at ECPT. Recommendations are made to management to pay attention to the autocratic leadership style as this style has been proven by researchers to have a negative effect on employee motivation. Motivation is described as the force within us that stimulates, directs and sustains our behaviour. The research study further explored the perceptions of employees on motivation. Maslow’s hierarchy of needs theory was explored as part of the motivation theories. Results based on this theory revealed that the Physiological needs of staff at ECPT are not met. These needs include biological needs such as water, food and air. Chapter 2 of the Constitution of South Africa states that everyone has the right to have access to sufficient food and water. In light of the constitutional requirements on human rights and legislative environment that ECPT operates in, it is recommended that management ensures employees have access to clean water and basic sanitation and accommodation, particularly in the working environment. McClelland’s needs ix theory revealed that staff at ECPT have a high need for achievement, moderate need for power and a low need for affiliation as respondents remained neutral on whether their needs for affiliation were met. It is recommended that management adopts initiatives such as team building, meeting teams regularly to communicate departmental strategies and to involve staff in decision-making and policy updates. The study confirms that when employees are motivated, they go the extra mile in fulfilling responsibilities and by ensuring that staff morale is considered and boosted, ECPT stands to benefit from a motivated workforce that will lead the department in excelling on its mandate of ensuring that the lives of the people of Eastern Cape are improved. It further adjudicates that the appropriate style of leadership is needed that will augment staff morale. , Thesis (MBA) -- Faculty of Business and Economic Sciences , Business School, 2020

- Description: South Africa’s disappointing economic performance over the last decade has resulted in a socio-economic crisis, with unemployment and inequality rates being of the highest rates anywhere in the world. Furthermore, unemployment is concentrated among the young, unskilled, and previously disadvantaged population posing a considerable threat to South Africa’s new democracy. Internationally, a method to absorb job seekers into the economy is to make small business the engine-room of economic growth and development. Consequently, the South African Government has identified in its National Development Plan the establishment of small businesses as a priority, including the development of small businesses in rural and marginalised communities. As rural communities in South Africa experience systemic problems such as the lack of infrastructure, financial capital, skills and potential markets, establishing enterprises in rural settings is often more complex than those more advanced parts of the economy elsewhere where fewer constraints exist. This makes the task of establishing and growing rural entities particularly challenging, suggesting bespoke policy and support is required. This study analyses the literature to gain an understanding of economic development theory and how this intersects with and informs small enterprise development policy. It then looks at South Africa’s strategy and policy framework pertaining to enterprise development. Specifically, the literature examines the role of rural enterprise development to establish whether this enables people to move out of poverty or further entraps people in poverty. The study collates data from a rural and marginalised community through observation and interview techniques. Firstly, multiple in-depth interviews were conducted with nineteen entrepreneurs in a rural community to collect data on business opportunities and explore the type of support entrepreneurs would require from government. Secondly, a focus group interview was conducted with entrepreneurs that had ii experienced institutional support to understand how well current policy and programmes support rural enterprise development. The primary data was analysed in conjunction with the literature on economic theory and enterprise development using the technique of triangulation to avoid logic leaps and formation of false assumptions. The insights and findings from the analysis reinforced certain facts within the body of knowledge pertaining to enterprise development, but there were also some interesting new insights that emanate from the data. South Africa has been able to introduce a wide range of policy initiatives and has multiple programmes and strategies to support small enterprise development. It has achieved firm success and impetus as well as experiencing certain failures. The study clearly highlights both and makes recommendations to improve policy promoting rural enterprise development as a means to alleviate poverty. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2020

This study analyses the literature to gain an understanding of economic development theory and how this intersects with and informs small enterprise development policy. It then looks at South Africa’s strategy and policy framework pertaining to enterprise development. Specifically, the literature examines the role of rural enterprise development to establish whether this enables people to move out of poverty or further entraps people in poverty. The study collates data from a rural and marginalised community through observation and interview techniques. Firstly, multiple in-depth interviews were conducted with nineteen entrepreneurs in a rural community to collect data on business opportunities and explore the type of support entrepreneurs would require from government. Secondly, a focus group interview was conducted with entrepreneurs that had ii experienced institutional support to understand how well current policy and programmes support rural enterprise development. The primary data was analysed in conjunction with the literature on economic theory and enterprise development using the technique of triangulation to avoid logic leaps and formation of false assumptions. The insights and findings from the analysis reinforced certain facts within the body of knowledge pertaining to enterprise development, but there were also some interesting new insights that emanate from the data. South Africa has been able to introduce a wide range of policy initiatives and has multiple programmes and strategies to support small enterprise development. It has achieved firm success and impetus as well as experiencing certain failures. The study clearly highlights both and makes recommendations to improve policy promoting rural enterprise development as a means to alleviate poverty. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2020
