- Description: Colorectal cancer (CRC) has become a health burden, being the third common cancer worldwide. Treatment of colorectal cancer is very important to manage the high prevalence rate of this disease. The available treatments for CRC have their drawbacks and side effects. Available treatments of colon cancer include surgery, chemotherapy, and radiation. Due to the side effects associated with these treatments, alternative treatments that pose less side effects are being developed worldwide. Nanotechnologies have gained global consideration due to their potential to improve the current standards and techniques for the diagnosis and treatment. The use of plants for synthesis of gold nanoparticles has opened a new venture of synthesizing environmentally friendly and cost-effective nanoparticles which possess great properties for CRC treatment. The aim of this study was to investigate the use of green synthesized AuNPs from Bridelia ferruginea for potential cancer treatment. In this work study gold nanoparticles were synthesized utilizing Bridelia ferruginea stem bark extract. The nanoparticles were characterized using UV–Vis spectroscopy, Dynamic Light Scattering (DLS), Fourier Transform Infrared Spectroscopy (FTIR) and High-Resolution Transmission Electron Microscopy (HRTEM). The in vitroanti cancer activity of the AuNPs was investigated using Presto Blue assay, cellular morphology, caspase 3/7 assay on the human colon cancer cell line at different times to assess the optimum time for cell death. The cellular uptake and localization of AuNPs was investigated using HRTEM to assess uptake and location of the AuNPs within the cell. Results obtained from this study showed that the AuNP synthesis from Bridellia ferrugenia was successful. The Presto Blue cell viability results showed that the AuNPs reduced cell viability (%) significantly (p<0.05) after 24 h. The optimum treatment time of HT-29 cells with AuNPs was determined to be 24 h. The apoptotic effects of the AuNPs were assessed using Cell Event reagent, and the results from this assay indicated that caspase 3/7 was activated with treatment with AuNPs which induced cell death via apoptosis. The HRTEM results indicated that there was no uptake of AuNP targeting in HT-29 therefore localization could not be determined. It can be concluded that the AuNPs synthesized from Bridellia ferrugenia have anti-cancer properties and are able to induce cell death through apoptosis. Furthermore, this study revealed that optimization of the AuNPs for cellular uptake is needed to further understand the interaction between the nanoparticles and the cells. This will provide more insight on how cellular death is induced by the nanoparticles. , Thesis (MSc) -- Faculty of Science, Department of Biochemistry and Microbiology (including Physiology), 2021

- Description: Water availability is one of largest constraints on plant survival, growth, and species distribution globally. The recent escalation in tree mortality coupled with declining precipitation and amplified temperatures has implicated drought as a major cause behind many large-scale dieback events observed across the world. Raising the question, what makes some species more resistant and persist while others dwindle and vanish from the landscape? The observed variability in species drought susceptibility demonstrates the complexity of physiological responses of plants to changes in water availability. Hydraulic dysfunction in plants has been purported to be the key mechanism behind drought-induced mortality provoking interest in hydraulic traits and critical thresholds of xylem physiological function. The capability of species to maintain hydraulic functionality under drought strongly influences the survival and general productivity towards water deficits. Hence, two core objectives, and subsequently aims, of this thesis are firstly to investigate the effect of drought on Subtropical Thicket vegetation health and productivity, and secondly to examine the underpinning physiological mechanisms and functional thresholds relaying speciesspecific drought vulnerability within this semi-arid biome. In first data chapter, this thesis offers an assessment of vegetation change under drought and its influence on plant physiological function and productivity across a subsection of Subtropical Thicket distribution. Additionally, this chapter provides a regional scale perspective of drought on Subtropical Thicket flora in the Eastern Cape of South Africa. A severe anomalous dieback event, which coincided with extreme, accumulative drought conditions was observed in 2020. Employing a combination of field-based approaches and remote sensing, this chapter aimed to provide a comprehensive report of the extent and severity of crown defoliation and canopy dieback following this event, additionally describing predisposing and compounding factors. Based on Standardized Precipitation Evapotranspiration and Standardized Precipitation Indices this event began in 2015 and coincided with amplified temperatures, exacerbating evaporative demand. Aerial UAV surveys and field-based investigations were undertaken. Remotely sensed (RS) indices provided an avenue for extensive spatiotemporal investigations to uncover the extent of drought-related impact on vegetation productivity and discuss potential underpinning mechanisms behind drought-induced mortality in Subtropical Thicket. Leveraging long-term time series RS data, Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI), from Moderate Resolution Imaging Spectroradiometer (MODIS) satellites as a proxy vegetation physiological status in combination with SPI and SPEI describing drought condition and groundbased surveying defining canopy vitality condition this study incidentally addressed the aim of endeavoring to link drought-induced mortality and early warning symptoms observed in the field with RS time series data to describe drought impacts across Subtropical Thicket. Furthermore, the findings of this chapter demonstrate the spatial and temporal heterogeneity in drought impacts on Subtropical Thicket. The recent drought of 2015 till 2021 is the longest documented period for the past 50 years in which there has been no accumulated net positive water availability, this apparently perpetual state of water deficiency has enacted a high cost for vegetation productivity and growth for the study area, exhibited well by average NDVI values of less than -0.5 for over 70% of the research site. The findings of this chapter report, to the contrary of anecdotal suggestions in the literature, on the intrinsic tolerance of Subtropical Thicket and that ii drought has a far more significant role on overall vegetation productivity, growth, and mortality in this region. The second data chapter assess whole-plant physiological functionality during a drought event in the Eastern Cape, South Africa. This is the first study in Subtropical Thicket to quantify in situ hydraulic functional integrity under a natural drought event testing the leading hypothesis describing tree mortality – hydraulic dysfunction. This chapter firstly, investigates hydraulic traits (e.g., turgor loss point) and describe key physiological thresholds (e.g., P50) for maintaining function during drought. Secondly, levels of native embolism were determined under drought conditions and combined with measurements of xylem vulnerability to embolism providing an estimation of degree of hydraulic dysfunction experienced by six dominant woody canopy species in Subtropical Thicket – to quantify interspecific drought tolerance and susceptibility. Subtropical Thicket species exhibited remarkable tolerance towards desiccation (TLP from as low as -3MPa) and hydraulic functional resistance to embolism (P50 value as low as -7.89MPa). The observed unexpected drought resilience of subtropical derived lineages highlights the intrinsic evolutionary role aridification had, selecting for greater embolism resistance and community-level conservatism in drought resistance of Subtropical Thicket. The level of native embolism and hydraulic safety margins identified two species (Schotia latifolia and Polyagla myrtifolia) that were the most vulnerable, and a third (Pappea capensis) moderately vulnerable, then the remaining studied species – this could result in community-level adjustments in species composition and structure under future projected climate change scenarios where, increased frequencies of drought events are anticipated. This retrospective assessment of canopy vigor with physiological functional thresholds evokes hydraulic dysfunction as the principal mechanism of observed Subtropical Thicket dieback to drought. This chapter provides crucial in situ data for predictive assertions around drought-induced mortality risk in a phylogenetically diverse and climatically unique biome of southern Africa; and is the first to identify critical hydraulic thresholds for tree species within this region. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The study of happiness, originally with a basis in psychology and sociology, became more scientific when methods were found to measure the complex concept. Humanity believe that happiness is meaningful, important, and worth achieving because, it is one of the most significant dimensions of human experience and emotions. The rewards of being happy for individuals and society are many including health, positivity, and productivity. The debate rages on whether subjective wellbeing increases as gross domestic product increases in countries and cities. Research has affirmed that happy employees are more productive, thereby improving financial sustainable, financial results for organisations and society. The opposite perspective is that unhappy employees negatively affect the performance, moral of fellow employees leading to negative results for organisations and poor social conditions. The Steel Wire and Rope manufacturing plant serves many organisations worldwide, where large industries exist including mining, offshore, agriculture and general-purpose applications. The manufacturing industry in which the study is based is strategic to South African local manufacture with critical applications in mine winding, by hoisting materials and men to the surface from the deepest mines in the world. Achievements include the longest and heaviest rope in the world. Happiness in this industry has not yet been explored, making this study new in this particular industry. The Steel Wire and Rope factory are a manufacturing facility and manufacturing companies can benefit from improving employee happiness levels. This makes this study of a steel wire and rope manufacturing facility important, as it would provide insight into similar manufacturing industries. The purpose of the study is to understand the happiness levels of employees in the steel, wire and rope manufacturing facility. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: The study of happiness, originally with a basis in psychology and sociology, became more scientific when methods were found to measure the complex concept. Humanity believe that happiness is meaningful, important, and worth achieving because, it is one of the most significant dimensions of human experience and emotions. The rewards of being happy for individuals and society are many including health, positivity, and productivity. The debate rages on whether subjective wellbeing increases as gross domestic product increases in countries and cities. Research has affirmed that happy employees are more productive, thereby improving financial sustainable, financial results for organisations and society. The opposite perspective is that unhappy employees negatively affect the performance, moral of fellow employees leading to negative results for organisations and poor social conditions. The Steel Wire and Rope manufacturing plant serves many organisations worldwide, where large industries exist including mining, offshore, agriculture and general-purpose applications. The manufacturing industry in which the study is based is strategic to South African local manufacture with critical applications in mine winding, by hoisting materials and men to the surface from the deepest mines in the world. Achievements include the longest and heaviest rope in the world. Happiness in this industry has not yet been explored, making this study new in this particular industry. The Steel Wire and Rope factory are a manufacturing facility and manufacturing companies can benefit from improving employee happiness levels. This makes this study of a steel wire and rope manufacturing facility important, as it would provide insight into similar manufacturing industries. The purpose of the study is to understand the happiness levels of employees in the steel, wire and rope manufacturing facility. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMU Business School, 2021

- Description: In this study, we re-examine Fisher’s hypothesis for the South African economy during the post-inflation targeting era of 2002:Q1 to 2019:Q4, and in doing so, we present four noteworthy empirical contributions. Firstly, we employ two nonlinear frameworks to carry out our empirical analysis, i.e. i) Flexible Fourier Function (FFF) unit root tests, and ii) Nonlinear Autoregressive Distributed Lag model (NARDL). Secondly, we take the disaggregated approach in examining Fisher’s hypothesis by making use of survey-based inflation expectations data for financial analysts, the business sector, trade unions representatives, and household participants. Thirdly, we capture our inflation expectations using three different forecast horizons (i.e. current, 12-month ahead, and 24-month ahead). Lastly, we conduct a sensitivity analysis. After employing our FFF based tests, the empirical results highlighted the Reserve Bank’s success of stabilizing real interest rates for periods subsequent to the 2008 Subprime crisis, as compared to periods before the crisis. Furthermore, after employing the NARDL model, we observed that nominal interest rates are more responsive to the falling inflation expectations across all economic agents except for trade unions during the pre-crisis period. On the other hand, nominal interest rates were found to be more responsive to rising expectations of all economic agents in the post-crisis period. Essentially, our findings have important policy implications for monetary policy. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: Recent unfavourable macroeconomic and socio-economic conditions have placed South Africa’s economy in a difficult fiscal situation with rapidly growing public debt and large government deficits. South Africa’s government expenditure cuts and tax hikes have not achieved the goal of Public debt reduction and economic growth has been shrinking, recorded to have shrunk by an annualised 0.6% in 2019. Fiscal policy is a mix of government spending and tax and this study reviewed the tax side of fiscal policy and its effectiveness in reducing government debt, the study further explored the behavioural factors that influence taxpayers’ decisions to comply with tax and the strategies that can be used to increase compliance and improve tax administration and collection by the South African Revenue Services (SARS). This study employed the ordered logistic model to compare the behaviour of South African citizens towards tax compliance and tax evasion. findings revealed that the perceptions, attitudes, and behaviour of South African citizens have generally shifted from a society that values tax compliance to a nation that justifies cheating on taxes. The main behavioural factors that shape perception and behaviour towards tax compliance and tax evasion were found to be amongst others demographic factors such as age, level of education, employment status, social class, income level, and ethnic group. In addition to demographic factors, the level of confidence and patriotism have proved to be important variables that shape taxpayers’ compliance decision. Regarding the aforementioned variables, the study found that the level of confidence in the government has significantly reduced as well as the degree of patriotism. , Thesis (MA) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: Post the 2008/09 global economic and financial crises, increased calls have been made for exploration and consideration of alternative sources of funding for economic development at a local level. To limit dependence on restricted and sometimes dwindling public finances from central government, many countries in the world have considered various alternative forms of financing. In South Africa, only four of the eight metropolitan municipalities (in short metros), have introduced municipal bonds primarily to finance their infrastructure development initiatives. Having noted the reluctance of metros and secondary cities in South Africa to explore alternative sources to finance their local economic development (LED) initiatives, this study advocates for the use of municipal bonds in the Mangaung Metropolitan Municipality (henceforth Mangaung Metro), as an alternative source of finance for its LED initiatives, especially its infrastructure development programme. The study further presents evidence for the other metros in South Africa, where municipal bonds have worked as an additional and/or alternative source of finance. Using analysis of socio-economic conditions as well as selected financial ratios, the study compares Mangaung Metro to the other four metros that have issued municipal bonds in order to assess the state of readiness and the viability of a municipality bond for the metro. On the analysis of socio-economic conditions, this study found that on the one hand, the Mangaung Metro lags all the other metros under review on almost all the indicators, whilst the economic and labour market data highlights the development potential of the metro. On the financial analysis, the study found that Mangaung Metro’s financial situation seems to have been improving and could have been described as sound up to 2015/16, and that the deterioration in the metro’s finance coincided with the changes in the political and 6 administrative leadership and management of the metro. , Thesis (MPhil) -- Faculty of Business and Economic Sciences, School of Economics Development and Tourism, 2021

- Description: The study investigated the factors influencing retention of academic staff at South African Higher Education Institutions (HEIs). The Job Embeddedness theory and Herzberg’s theory on retention were used to explore the retention of employees with special focus on the challenges and strategies of enhancing retention. The study adopted desktop research to explore the retention of academic staff in HEIs. This study discussed the challenges and factors influencing staff retention in universities and Technical and Vocational Education and Training colleges (TVETs) in South Africa. The findings of the study revealed that the challenges that impede staff retention include a lack of capacity; massification of tertiary education; transformation of higher education; redressing historical imbalances; staff turnover; a lack of mentoring and coaching; and the impossibility to satisfy everyone’s needs. The study identified strategies that can be adopted to enhance staff retention that focus on remuneration and compensation; professional development; workplace climate; appointments and promotions; institutional governance; institutional infrastructure and adaptation to change. Factors that contribute to effective staff retention were also identified as organisational culture; the rewards system; mentoring and development programmes; retention tracking, recruitment; selection; the life cycle of an employee; onboarding; performance management systems, career management, bureaucratic organisational structures; and effective support from Deans and Vice-Chancellors. Lastly, the study recommended the following on how HEIs can retain their academic staff: career advancement opportunities to boost morale and loyalty of the staff; mentoring and coaching provided to the junior staff by the senior staff; job satisfaction through the provision of remuneration and rewarding performance; and implementing sound performance management and appraisal systems. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2020

- Description: The process of deciding on a career is a dauntingand life-changing decision,which all scholarshave had to make. Various factors influence a first-year student’s career choice decision and selected field of study. Career decision-making,as a field of study, has been extensivelyresearched,globally. The research studies focusingon IT career choicesof studentshave indicated that scholars choosing careers in Information Technology (IT) are influenced by factors such as salaries, knowledge of career opportunities, the reputation of IT-related fields in society and by parents, teachers and role models. Recent research indicates that exposure to new technologies and programming concepts at the school level can influence a scholar’s IT career choice. Theories relating to career choice have focused on the characteristics of individuals and their environment. Career choice models have identified factors that influenced a student’s career choice.In South Africahowever,there have been limited studies investigating the factors influencing students’ career decisions in choosing careers in Computer Science (CS), Information Systems (IS) and Information Technology (IT)using mixed-methods.This study aims to investigate the factors that influence first-year students’ decisionsin choosing an IT career at the Nelson Mandela University.The research study pursueda pragmatisticapproach,using a mixed-methods approach. In investigating theories andfactors that influence students’ decisionsin choosing IT careers,the study used systematic literature reviews. The decision-making theories and factorsin theliterature review facilitated the creation of the conceptual framework for IT career decision making. A questionnaire was developed and distributed amongst ITand Non-ITfirst-year studentsin 2021. Fourhundredand eightparticipants completed the survey. The data obtained from the survey were statistically analysed, includingdescriptive analysis andExploratory Factor Analysis(EFA). Additionally, inferential statistics were used namely; Correlations, t-test, Confirmatory Factor Analysis(CFA)and Structural Equation Modelling(SEM). The study results wereinterpreted andcompared with iiiotherrelevantstudies. Recommendations were madeto address the factorsthat influencefirst-year students’ IT career decisions.The study highlighted that high academic confidence and personal attributes amongststudents,whowereinvolved at an early age in programming and using computers,chose IT as a career. The study showed significant statistical differences betweenIT and Non-IT groups in perceptions about the IT industry and identifying job title descriptions.Additionally, a significant statistical difference between languages and genders was identified in understanding careers. , Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 2021

- Description: This study sought out to empirically investigate whether it is export diversification or export concentration that would help achieve and sustain higher economic growth in the G20 countries using data over the period of 1995 to 2017. The empirical analysis uses the Autoregressive Distributed Lag (ARDL) model within a Pooled Mean Group (PMG) to evaluate the existence of a long run cointegration and as a baseline for examining whether the relationship between export diversification (concentration) and growth is nonlinear through a Nonlinear Autoregressive Distributed Lag (NARDL) model. The ARDL model confirms that the is a long run cointegration between the variables where both export diversification and concentration have a positive impact on growth. On the other hand, the NARDL model confirms that the relationship between export diversification and growth in the G20 countries is a nonlinear where a positive change in diversification has a negative effect on growth, while negative changes have a positive effect, thus, diversification has a negative effect on growth. The NARDL results for concentration do not confirm any nonlinearities, this implies that both positive and negative changes in concentration have negative and statistically insignificant effects on growth. Both the panel ARDL and panel NARDL model are superior models that can account and correct any serial autocorrelation that may exist, thus making the results robust enough. Seemingly, that both export diversification and concentration have a negative effect on growth and this effect may be attributed to the sample being a mixture of developed and developing economies, the study further analysed the effect on to sub-samples (G7 and non-G7). The results for the G7 panel show that there is no evidence of a nonlinear relationship between growth and concentration, as a positive change has a positive effect and a negative change has a negative effect. Overall, the G7 NARDL results are show that concentration will accelerate growth in developed economies in the long run more than diversification. The results for the non-G7 panel the NARDL results show that there is a linear relationship between export diversification (concentration) and growth. The overall, results of the study suggest, that for the G20 countries developmental levels need to be considered in order to know the correct export composition strategy to adopt in order to accelerate growth. With that said, in developed countries like the G7 export concentration would be beneficial in accelerating growth, while in developing countries like the non-G7 countries export diversification would accelerate growth. , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 2021

- Description: This study explores the nature and scope of food insecurity among postgraduate students at Nelson Mandela University, South Africa. The study employed a mixed method approach to access postgraduate students and university officials to investigate the prevalence of food insecurity. The approach also assesses the demographic factors; academic and mental implications along with the coping mechanisms associated with the experiences of food insecurity in higher education South Africa. The study incorporates an adapted conceptual framework from Alaimo’s food insecurity socio-economic risk models (2005) to understand the higher education context. Alaimo’s model seeks to connect the household conditions and broader systematic socio-economic mechanisms that households adopt to secure food. This model was adapted and employed in understanding the data collected while using a mixed-method approach between June and August 2021. The study employed an online survey for only postgraduate students enrolled at Nelson Mandela University (NMU) during the time of the study. This was supplemented by semi-structured interviews with student affairs officials that are directly involved in the formulation of strategies used to alleviate food insecurity at NMU. With 78 postgraduate students responding to the online survey, the study seems to confirm some of the studies done in this field on the inadequacy of food banks and food gardens in addressing food challenges effectively on campus. Similarly, the study found that the experiences of food insecurity were prevalent amongst postgraduate students that identified as black, low-income, and making access of the campus clinic for food relief. The study concluded by recommending a collaborative and a multi-level systematic approach in alleviating food insecurity in higher education. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: While there is extensive research exploring the influence of a client’s cultural beliefs on the therapeutic process; there is still a scarcity of information on how the cultural beliefs held by a psychologist may affect or influence the therapeutic process. Psychologists are trained to work with clients objectively by suspending their own beliefs, ideas, and values. Despite this, it would be interesting to explore how South African psychologists’ personal belief systems are navigated within the therapeutic space. Given the diversity of cultures within the South African context, it becomes important to explore and understand psychologists’ cultural belief systems, as they may influence the therapeutic relationship but to also, understand how they assimilate these belief systems into the therapeutic relationships with diverse clients. Drawing on the qualitative methodology, the study sought to draw participants using a purposive sampling technique. Participants were sourced through different databases, such as the Eastern Cape database of registered and practicing psychologists. Participants who agreed to partake in the study were sent an email with the interview schedule and the link to either MS Teams or Zoom, depending on their preference. The collected data was transcribed and then analysed using thematic analysis through which three themes and six sub-themes were identified and discussed. The identified themes are as follows; 1) Culture as perceived by psychologists, 2) Cultural beliefs in therapy and, 3) The therapeutic alliance. The study found that shared cultural beliefs between psychologists and clients facilitated rapport building. It allowed the therapeutic process to move in a positive direction. The study applied the principles of ethics and trustworthiness. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: Social workers are mandated to address environmental justice issues as part of working towards promoting community and environmental sustainability within and between communities. This thesis reports from a research study that was aimed at exploring the preparedness of social workers to address pollution in King Sabata Dalindyebo communities with the objective to: understand the social work intervention strategies social workers use to address pollution in KSD communities; identify the challenges if any social workers face when addressing pollution in KSD communities; and explore the confidence of social workers when addressing pollution in KSD communities. To achieve its aim and objectives, this study was exclusively informed by a qualitative research approach and thus utilised an explorative case study design to obtain in-depth qualitative data. Semi-structured interviews were conducted with twelve social workers using a semi-structured interview guide. The interviewed social workers were sampled utilizing convenience and snowball sampling techniques. Mass collected data was analysed thematically and thus presented according to themes and subthemes. Findings indicated that social workers are not sufficiently prepared to address pollution in KSD communities because of lack of environmental education and training, coupled with lack of enabling resources. Therefore, this study recommended environmental social work education and training through organisational workshops as well as improved support and resourcing. This study also recommended a future study that will explore the progress of social work towards promoting environmental sustainability in communities. , Thesis (MSW) -- Faculty of Social Sciences and Humanities, 2021

- Description: This study aimed to exam the implementation of the Department of Social Development’s Fatherhood Strategy by Families South Africa (FAMSA) Eastern Cape. FAMSA is a non-profit organization providing vital services to people in families while providing them with psychosocial and emotional support. FAMSA has been in existence since 1954. To achieve this aim, the study’s objectives were underpinned by understanding the implementation of the Department of Social Development’s Fatherhood Strategy in Buffalo City Metro, establishing FAMSA’s response to the implementation of the Department of Social Development’s Fatherhood Strategy as well as exploring the challenges faced by FAMSA in implementing the Department of Social Development’s Fatherhood Strategy. A qualitative research methodology was implemented to gather information from FAMSA and DSD. Findings from literature revealed that the fatherhood strategy has been a concern worldwide evidenced by the high levels of father-child non-residency. Data from this study revealed that FAMSA had been implementing the programme effectively regardless of numerous challenges that include funding human resources. Conclusively, a lot must be done to advocate for fatherhood. Recommendations also point to the need for several interventions which need to be done in research, social work practice and also policy formulation and development. , Thesis (MA) -- Faculty of Social Sciences and Humanities, 2023

- Description: Public programming initiatives are an integral part of archival operations worldwide as they support the greater use of archival records by attracting prospective users and sponsors. Public programming comprises a sequence of strategies for publicizing and marketing archives to the public, which are crucial in archival operations as they promote better use of archives and records.

Services depends on provisions of the National Archives of South Africa Act of 1996 in its strive to promote access and use of archives as sources of information. . unknown and therefore not used to their maximal utility value, likely due to low-key and ineffective archival public programming initiatives. Consequently, the primary purpose of this research study was to evaluate the extent of public programming strategies used by the Eastern Cape Provincial Archives and Records Services (EAPARS). The study used a mixed-method, embracing qualitative and quantitative research approaches. As an integrated record-keeping framework, Record Continuum was used as a theoretical framework to guide the study. Sixteen copies of questionnaire were distributed among staff and users ECPARS. The research uncovered that ECPARS does not have specific regulations and policies on public programming, but relies on the more general provisions of the Provincial Archives and Records Services Act of 1996 as a guiding instrument in executing its public programming operations. The study further revealed various factors, such as the limited budget and inadequate staff, as key hindering factors in the smooth execution of archival public programming plans by ECPARS. The study recommends a review and update by ECPARS of how it can specifically effectively implement the provisions of the 1996 Act to the modern ways of taking public archives to the people. The research also recommends that ECPARS engage additional staff or outsourced services to strengthen its the public programming of its archival resources and services workforce for Eastern Cape Provincial Archives and Records. The study concludes that improved financial resources, use of ICTs, and coherent policy framework, and public awareness creation and education can facilitate better to acquire, widen access to use of its archives.

- 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
