- Description: Strategy implementation faces many challenges within the public sector of South Africa. Previous research suggests that factors such as strategy formulation, strategy control and follow-up, leadership and suitability motivation, management and employees and corporate governance leading the change influence strategy implementation to various degrees. These factors are said to influence strategy implementation positively. The aim of the study was to investigate the relationships between the above-mentioned independent variables against a dependent variable, namely, strategy implementation. In the literature review, various topics such as leadership, strategy formulation and motivation, were discussed. Descriptive statistics were derived with regard to the prevailing levels of the various independent variables within the Coega Development Corporation. The sample of this study consisted of 50 employees at different levels within the Coega Development Corporation in the Eastern Cape. The regression analysis of this study showed that all factors were statically significant except leadership and suitability motivation, management, and employees. This factor was found to be statistically insignificant as the p value was greater than 0.05 (p= 0.169289). Furthermore, the statistical data analysis indicated that strategy implementation within the Coega Development Corporations is influenced positively by factors such as strategy formulation, strategy control and follow-up and corporate governance leading the change. The managerial implications of the empirical results were discussed in the study. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: South Africa is the third largest economy on the African continent. Moreover, it is the most technological, industrialised and diversified economy in Africa. Its economy consists of various sectors, such as mineral resources, financial, services and manufacturing sectors, as well as other sectors. It is imperative that these sectors are and remain competitive as they impact directly on the economy of the country and the continent which has an impact on all citizens in the country. An important resource is that of human resources in these sectors. Employees in these sectors form part of various departments of the specific organisation they are employed by, with their own duties and responsibilities. All departments in an organisation have an integral part to play to ensure that an organisation is indeed successful and sustainable. The human resources department plays an integral role and provides service to the various departments and thus impacts the success of the organisation. The HR practitioners who work within the HR department need to be engaged to fulfil their duties effectively. The purpose and primary objective of this study was to identify factors that influence the engagement of HR practitioners. To achieve this, a quantitative research approach was followed. HR practitioners were sent an electronic survey questionnaire to gauge their levels against communication, leadership support, meaningful work and rewards and recognition. The data from the empirical study was analysed by using descriptive and inferential statistics. The study was also tested for validity and reliability. The study concluded with recommendations on how HR practitioners can be further engaged. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: the change in South Africa, post the apartheid regime when the labour laws were amended and the law of equality instilled, women are still under-represented in the construction industry of South Africa, particularly in senior management positions. The purpose of this study was to investigate the factors affecting the career growth of female engineers in the construction industry of South Africa. The study was guided by the following objectives: to investigate if education influences women’s career advancement in the construction industry of South Africa, to establish the extent to which gender negatively impacts women’s career advancement in the construction industry of South Africa, to determine the rate at which women are promoted to senior leadership positions in the construction industry of South Africa, and to establish the extent to which the construction industry of South Africa goes to retain women within the industry. According to the study's findings, women in South Africa's construction industry have prospered from their qualifications (education). They stated that their education influenced their career path. The respondents believe that their gender does not prevent them from pursuing management positions. Women's retention in the construction industry is gradually improving. It was suggested that women be allowed more liberty in leadership roles so that they can perform to their full potential. Flexible working hours must be made available to women in order for them to be able to manage job and family obligations. This is not to say that women aren't capable; rather, it's a means of inspiring and recognising that, just as they are in the office, they are also leaders at home. , Thesis (MA) -- Faculty of business and economic sciences, 2022

- Description: Spaza shops, originating in South Africa during the 1970’s, often operate in townships, selling products and services to customers who live mostly within walking distance of the shop. Almost five decades later, and spaza shops abound across most townships in South Africa. These businesses not only provide grocery items and services to customers in the township community but are a means for people to earn a livelihood for themselves and also contribute economically through creating employment opportunities in the informal sector. Research about spaza shops shows that there is a growing customer interest in purchasing products and services from spaza shops, and that if spaza shops are to continue growing, they need to be more competitive. Research by renowned authors in the field of experience marketing, Pine and Gilmore (2013) puts forward that experiences are the new relevant economic offering, and an essential value creating platform for businesses to be more competitive. However, before customer experience can be enhanced in spaza shops, it is important to first identify the factors that influence customer experience in a spaza shop context. Considering the latter, the primary objective of this study was to measure factors that influence customer experience in spaza shops. A descriptive research design was selected for this study, followed by a positivistic research paradigm and quantitative research methodology. Secondary data was collected through articles, journals, books and from newspapers. Primary data was collected using a survey in the form of a self-administered questionnaire. The target population for this study was customers who are older than 18 years, who had bought grocery items (products and services) in spaza shops located in Nelson Mandela Bay townships specifically in Walmer Township, KwaZakhele, Zwide, Motherwell, KwaMagxaki and New Brighton. A non-probability sampling method and convenience sampling technique were used to distribute a total of 200 selfadministered questionnaires. Once the data collection phase was completed, the data from the questionnaires was recorded, coded, and cleaned on a single excel spreadsheet. After the latter was done, a total of 185 questionnaires were deemed useable and considered for data analysis, which was conducted with the aid of IBM SPSS Statistics version 27 (computer software). , Thesis (MCom) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2022

- Description: Given the historically disadvantaged position of women and their heavy reliance on climate-sensitive activities in many societies, the vagaries of the climate threaten the agrarian livelihoods of women in Chivi district. This study focuses on the impacts of climate change on women working in agriculture in one ward of Chivi district and on the feminization of agriculture during the period from 2000 to 2019. It explores how the roles of women have changed in agricultural production and in relation to household food security. It assesses women’s involvement in decision-making in agriculture as well as in household food security, and analyses the socio-economic impacts of climate change on women subsistence farmers, exploring the adaptation strategies that rural women working in agriculture implement in response to climate-risk events and threats. The study was influenced by ecofeminist theories and the Sustainable Livelihood Framework. Comparative analysis of household types was done after data gathering using participatory rural appraisal tools with women from three villages. Interviews were conducted with key informants from government departments and development institutions. The results show that climate-risk events and threats have resulted in feminization of agricultural labour as men branch out into wage labour, but that changing power relations in the form of decision-making in agriculture and issues related to household food security vary with the type of the household. Worsening climatic conditions have made it difficult for women to ensure household food security and to generate income through agrarian livelihoods. However, women have implemented adaptation strategies including conservation agriculture to mitigate crop failure, and to improve agricultural output and household daily consumption, and thus survive peak hunger periods. The study contributes to our understanding of the resilience of women in the Global South to climate-risk events and threats and contributes to our understanding of participatory rural appraisal tools in addition to conventional data collection tools. The study recommends that development institutions promote gender equality and that development institutions construct dams, rehabilitate collapsed irrigation schemes and accelerate the implementation of novel climate smart technologies in arid regions. , Thesis (PhD) -- Faculty of Business and Economic science, 2022

- Description: As top predators, seabirds occupy the upper trophic level of marine ecosystems. They are consequently important for the maintenance of ecosystem structure and function, while also possessing characteristics which are useful for identifying climate-driven changes in oceanography at all trophic levels. This important faunal group is one of the most threatened, with climate change and fisheries bycatch mortality being the primary drivers of population declines. Understanding these threats is important for the management of threatened seabird populations. One impact of climate change and variability in climate occurs through changes in prey availability. As central place foragers, breeding seabirds have trip duration constraints due to the obligation of nest duties. This makes them particularly vulnerable to changes in prey availability within their foraging ranges. The ability to adjust foraging behaviour during environmental conditions which alter prey availability is an important attribute which can contribute to breeding success. Thus, investigating for this foraging behavioural plasticity during different breeding stages provides insights into how a species is likely to be impacted by climate change. The sooty albatross population on Marion Island was studied and displayed a degree of foraging behavioural plasticity during the five-year period of pronounced climatic variability studied. Incubating birds mainly foraged in the subtropical convergence zone (STCZ), the Sub Antarctic Front (SAF) and Subtropical Front (STF) which border it, and the region north of the STF. Brooding birds mainly used the SAF and Polar Frontal Zone (PFZ). Significantly different areas were used between years during both breeding stages. This population showed a lack of consistent habitat preferences which may offer resilience to progressive climatic variability and change. Interactions of sooty albatrosses, as well as white-chinned petrels for comparative purposes, with fisheries were also assessed. The two species were compared to shed light on possible explanations for differences in seabird-fishery interactions between the species. The impact of fisheries-related mortality (bycatch) is dependent on exposure to fishing activity and attraction to fishing boats encountered while foraging. Bycatch mortality has previously been proposed as the main cause of this sooty albatross population’s decline. Exposure and 6 attraction to fishing boats was found to be lower than that of white-chinned petrels which are bycatch prone. However, the current level of attraction exhibited by this sooty albatross population may expose a significant fraction of the population to bycatch risk due to its small population size. Additionally, all fishing boats were encountered north of the STF where non breeding individuals are now known to be distributed. Thus, the impact of fisheries on this population may mainly be mediated by more bycatch prone non-breeding individuals. Overall, the relative impact of fisheries bycatch mortality is suggested to be higher than that of climatic impacts on the sooty albatross population on Marion Island. However, this study did not incorporate dietary and demographic information which would reveal whether there are nutritional differences between years that may impact on breeding success. An integrated rather than independent assessment of foraging behavioural responses to climatic variability and fishing activity is recommended for improving our understanding of current and future conservation priorities. , Thesis (MSc) -- Faculty of Science, Zoology , 2021

- Description: The study analyses the role that hard and soft infrastructure plays in attracting FDI inflows in the SADC region. As proxy for soft infrastructure, Internet users and governance indicators were used. Panel data was used for the analysis, for sixteen SADC member states, covering the period 2000 to 2018. Data was analysed using the multiple linear regression technique, applying the Random Effects Model. The results show that for soft infrastructure, government effectiveness (positive) and rule of law (negative) plays a vital and significant role in attracting FDI inflows into the SADC region. For hard infrastructure, telephone density and gross capital formation have a positive relationship with FDI. Soft infrastructure was found to be of more significance in attracting FDI inflows compared to hard infrastructure. Other variables, such as population growth rate, market size and trade openness were also found to have a significant relationship with FDI inflows in the SADC region. The study concludes that, although soft infrastructure plays a more significant role the two forms of infrastructure play a complimentary role in the attraction of FDI. To improve FDI inflows in SADC, the study recommended that SADC member states must dwell more on improving soft infrastructure, but also working on hard infrastructure development and making policies that attract FDI in the region. SADC countries should consider consolidating their policies towards both soft and hard infrastructures to obtain some form of convergence on infrastructural levels within the region. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: Various pharmaceutical materials are known to take up moisture during both storage and manufacture. This phenomenon, termed hygroscopy, can result in unacceptable levels of moisture, potentially having deleterious effects on product quality, and consequently product efficacy and safety. Drug inefficacy specifically can result in life-threatening complications for the pregnant mother with uncontrolled blood pressure. Marketed as immediate release tablets, methyldopa is an antihypertensive drug commonly used in South Africa to treat hypertensive disorders of pregnancy. Despite being in use for over 50 years, the physicochemical challenges posed by methyldopa remain ever present. Methyldopa is not only significantly hygroscopic, but also prone to oxidative and hydrolytic degradation that can be accelerated by moisture. Poor compression behaviour, another limitation of methyldopa, leaves the formulation scientist with a constellation of formulation hurdles that must be faced, understood and overcome. This is a task that can be tackled using elements of the Quality by Design (QbD) approach. Using this approach, the impact of these phenomena on tablet quality can be better understood and controlled. This study was aimed at using this approach to develop a formulation of methyldopa 250 mg tablets. Direct compression, a simple and moisture-free process, was selected for the manufacture of methyldopa tablets. After careful review of literature and consultation with experts, excipients were selected for the candidate formulation and preliminary concentrations established for each. Similarly, settings for mixing and compression variables were established. Adopted from the QbD framework, the risk posed to tablet quality by these factors was qualitatively analysed using Preliminary Hazard Analysis (PHA) and quantitatively evaluated using Failure Modes and Effect Analysis (FMEA). Eight (8) factors determined to be high risk were further investigated in a preliminary experiment that followed a 12-batch Plackett Burman design. Data from this experiment was used to draw statistical relationships between the aforementioned factors and tablet quality attributes, thus shedding light on excipients and process parameters with practically significant impact on methyldopa tablet quality. Multivariate Analysis of Variance (MANOVA) of the response data reported SSG concentration, citric acid monohydrate xxvii concentration and mixing speed as key factors (p<0.05), demonstrating the need to control these factors for quality targets to be met. These three factors underpinned the 16-batch definitive experiment that followed, conceived using a Box Behnken design (BBD) including four batches prepared at the centerpoint values in the region of experimentation. The optimal methyldopa tablet formulation was achieved at the following settings: 1.0 % m/m magnesium stearate, 1.0 % m/m colloidal silica, 3.9 % m/m sodium starch glycolate, 1.7 % m/m citric acid monohydrate, mixing speed of 101 rpm, 6 minutes of pre-lubrication mixing, 2 minutes of lubrication and compression speed of 20 rpm. These settings were included in the design space and subsequent control strategy. It was learned that, within the design space, the risk to tablet quality and, by extension, the patient, was insignificant. This demonstrated that, using the QbD approach, challenges to pharmaceutical development can be effectively overcome. , Thesis (MA) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Various pharmaceutical materials are known to take up moisture during both storage and manufacture. This phenomenon, termed hygroscopy, can result in unacceptable levels of moisture, potentially having deleterious effects on product quality, and consequently product efficacy and safety. Drug inefficacy specifically can result in life-threatening complications for the pregnant mother with uncontrolled blood pressure. Marketed as immediate release tablets, methyldopa is an antihypertensive drug commonly used in South Africa to treat hypertensive disorders of pregnancy. Despite being in use for over 50 years, the physicochemical challenges posed by methyldopa remain ever present. Methyldopa is not only significantly hygroscopic, but also prone to oxidative and hydrolytic degradation that can be accelerated by moisture. Poor compression behaviour, another limitation of methyldopa, leaves the formulation scientist with a constellation of formulation hurdles that must be faced, understood and overcome. This is a task that can be tackled using elements of the Quality by Design (QbD) approach. Using this approach, the impact of these phenomena on tablet quality can be better understood and controlled. This study was aimed at using this approach to develop a formulation of methyldopa 250 mg tablets. Direct compression, a simple and moisture-free process, was selected for the manufacture of methyldopa tablets. After careful review of literature and consultation with experts, excipients were selected for the candidate formulation and preliminary concentrations established for each. Similarly, settings for mixing and compression variables were established. Adopted from the QbD framework, the risk posed to tablet quality by these factors was qualitatively analysed using Preliminary Hazard Analysis (PHA) and quantitatively evaluated using Failure Modes and Effect Analysis (FMEA). Eight (8) factors determined to be high risk were further investigated in a preliminary experiment that followed a 12-batch Plackett Burman design. Data from this experiment was used to draw statistical relationships between the aforementioned factors and tablet quality attributes, thus shedding light on excipients and process parameters with practically significant impact on methyldopa tablet quality. Multivariate Analysis of Variance (MANOVA) of the response data reported SSG concentration, citric acid monohydrate xxvii concentration and mixing speed as key factors (p<0.05), demonstrating the need to control these factors for quality targets to be met. These three factors underpinned the 16-batch definitive experiment that followed, conceived using a Box Behnken design (BBD) including four batches prepared at the centerpoint values in the region of experimentation. The optimal methyldopa tablet formulation was achieved at the following settings: 1.0 % m/m magnesium stearate, 1.0 % m/m colloidal silica, 3.9 % m/m sodium starch glycolate, 1.7 % m/m citric acid monohydrate, mixing speed of 101 rpm, 6 minutes of pre-lubrication mixing, 2 minutes of lubrication and compression speed of 20 rpm.

- Description: African has relatively low levels of economic complexity as the continent is centred on the production and exporting of natural agricultural goods, non-renewable natural resources, minerals, and crude oil, additionally the agricultural sector continues to be the prevalent employer. The purpose of this study is to examine the relationship between governance, institutional quality, with economic complexity in Africa. Panel data for the period 1996 - 2019 is employed and the generalised method of moments (GMM) technique was selected due to the number of countries (36 countries) being more than the time periods (22 years). The Granger non-causality test of Juodis, Karavias, and Sarafidis (2021) is used to figure out the direction of causality between the variables used in the study. The GMM results indicate that governance and institutional quality have a positive effect on economic complexity. The Granger causality test suggests that there is one directional causality from governance to economic complexity and from institutional quality to economic complexity. It is recommended that African countries improve governance through electing selfless leaders whose goal is improve the lives of its individuals. With regards to institutions, Africa needs to adopt strategies that support institutional quality which in turn will promote economic complexity. Policy makers should also create an environment or policies that are conducing for domestic and foreign investments, which in turn would improve the continent’s economic complexity. , Thesis (MA) -- Faculty of Business and Economic science, 2022

- Description: This study sought to examine how the socio-ecologically displaced Tokwe-Mukorsi community in southern Zimbabwe grappled with adverse circumstances that threatened to obliterate their age-old food and livelihood practices after five years of being resettled 150km away in Chingwizi. The investigation is done against the backdrop of the dominant narrative on resilience, which often overlooks resilience outcomes associated with specific contextual experiences of socio-ecological disadvantage. The study examined the nature and character of emergent food and livelihood practices in Chingwizi, with a view to establishing how they were impacted by socio-political dynamics encountered vis-à-vis displacement, resettlement and in processes of attempting to recover. The study also examined how local narratives about the new food and livelihood practices in Chingwizi intersect with dominant resilience discourses, especially those related to climate change adaptation, sustainability and food security. A triangulated research design was utilised. It consisted of survey, focus group discussion, in-depth interview, and key informant interview. Qualitative research participants were selected based on their knowledge and experience on food and livelihood practices before and after displacement. This included the displaced flood victims that met this criterion, local leaders, government officials and local opinion leaders. The findings revealed that food and livelihood practices in Chingwizi had deteriorated over the five-year period under investigation. This was reflected in a diminution in livestock herds, crop production, income streams and average household monthly incomes. As a result, food insecurity was very high, and households were forced to rely more on donations. The displaced flood victims, however, adapted to the harsh conditions by engaging in a variety of livelihood alternatives, including food vending, buying and selling, craftwork, small livestock rearing, and migrating to neighbouring South Africa to seek employment opportunities. Nevertheless, efforts to rebuild food and livelihood practices were hampered by socio-political dynamics. This resulted in the loss of key livelihood assets, a situation aggravated by compensational injustice, contestations over land and resources by the host communities, dysfunctional social networks, and victims’ cultural ‘fixations’. The study concludes from these and other findings that achieving transformation in the form of adaptation, food security and sustainability following involuntary displacement and resettlement is more than just a question of resilience, and that displacement and resettlement are complex processes that create invidious dynamism for the stakeholders concerned. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2022

- Description: In 1994 the new democratic government of South Africa introduced the Reconstruction and Development Programme (RDP) which was aimed at massive infrastructure expansion. Tackling the housing crisis has been encountered by growing demands for low carbon footprint, reduced use of non-renewable resources and as part of the green agenda. In line with the Sustainable Development Goals (SDGs), the South African government set a variety of objectives aimed at achieving an environmentally sustainable future for all. While South Africa has embraced green economy principles, tested integrated approaches are still to be seen in housing construction. This study sought to explore the greening of Ndlambe green village in the Port Alfred area in the Eastern Cape Province of South Africa. To achieve the study objectives, a qualitative research approach was used, employing the case study research strategy and primary data was collected by means of focus groups. Community members, engineers, environmentalists and town planners constituted the study sample. Secondary data sources were also used in this study, along with field observation. The collected data was analysed using the thematic analysis technique. Findings from the study revealed that community members perceived Green village initiative as important and is required in South Africa given the challenges that are experienced such as energy consumption load shedding, water shortages. The economic value proposition of green building is measured through two different lenses, namely economic profit and social profit. The municipalities must take a leading role in by forming policies supporting environmentally friendly activities, with building being one crucial area. Recommendations from the study proposed that partnerships involving communities, private companies, the government and other various interest groups are imperative in order to accelerating the green building agenda. The government must be challenges to develop sustainable funding solutions for a green economy. Lastly, increased awareness about green building among the society may also drive better acceptability and ultimately, a strong social reputation. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: Globally, the construction industry is infamous for a high level of fatalities. Construction sites are a very important place, as a considerable number of workers are involved in the construction process and activities, and H&S is critical to reduce hazards and the risk of being injured at work. The aim of the study was to evolve a framework of interventions to mitigate hazards, diseases, illnesses, injuries, fatalities, stress, and absenteeism in the construction industry. The objectives were to determine: why workers become ill due to construction and the implications; the causes of stress among construction workers, and worker absenteeism; what injuries workers experience, and the causes of fatalities, and if the current control measures are sufficient or whether more can be done. The research process commenced with a literature review relative to hazards and risks in the construction industry. A quantitative study was conducted among civil engineers, site supervisors, and construction H&S officers (CHSOs) in the construction industry using a questionnaire. The salient findings of the study suggest that the existing H&S legal and regulatory framework is barely effective. Although building contractors are aware of the most common H&S hazards and risks in construction, compliance is irregular. The study concluded that the identification of H&S hazards and risks is critical to mitigate fatalities, injuries, and illness. H&S education and training, and hazard identification and risk assessment (HIRA) should be improved and intensified, and a comprehensive risk mitigation plan should be developed and implemented on projects. , Thesis (MA) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: In an online space where individuals are meeting and creating relationships, it is important to explore and understand the nuanced, complex psychological phenomena that occur. Current psychological research into the phenomena of online addictiveness has gained traction with international studies exploring and expanding on this phenomena. Definitions of internet addiction differ widely, but research indicates that addicts expend large amounts of time online and that using the internet becomes a significant part of their everyday lives. Consequently, exploring individual’s experiences of online addiction within a romantic context becomes more relevant. The aim of this study was to explore and describe adults lived experiences of addictiveness in the context of online romantic relationships by expanding on the previous data of Froneman’s (2016) study. The present study utilised a qualitative approach and was exploratory and descriptive in design. The sample size of the present study was seven adult participants and semi-structured interviews were utilised as the method of data collection. Themes including motivation for using online dating, spending time online and the Biopsychosocial dynamics were identified through the participant’s narratives. These findings ultimately can be used for future research. , Thesis (MA) -- Faculty of Health Sciences, 2022

- Description: Food waste is becoming an important issue considering greenhouse gas emissions from landfills. However, data on the quantities of food disposed remains limited, especially for developing, countries including South Africa. Global food waste estimates suggest that households in developed countries waste more food than those in developing countries. Further, research shows that lack of food waste management impacts negatively on the global efforts to combat food waste generation. I therefore set out to present primary data relating to household food waste generation and minimisation within a South African context. The case study covers two towns in the Eastern Cape province, namely Cradock and Middelburg, with a combined population of 55 352 people. Household food waste assessment and quantification was undertaken using two methods, 1) questionnaires to explore quantities of different types of food wasted by households, and 2) kitchen scales to measure the amounts of food discarded by households. Participating households in each suburb were selected randomly. Differences in shopping and household food waste behaviour in households from different income suburbs is vital to understand as it sets an effective approach to food waste interventions that might have a positive impact in minimising food waste generation. In this thesis, differences in shopping and household food waste behaviour across households in the affluent, middle and low-income suburbs is uncovered. A questionnaire was conducted and households in the affluent suburbs purchased food more frequently and had the highest percentage of respondents that used shopping list when buying food than those in the middle and low-income suburbs. The thesis also indicates that households in the low-income suburbs were more attracted to food special offers and had a higher proportion of respondents who could not distinguish between “Use by” and “Best before” dates than those in the affluent and middle- income suburbs. The reasons to food waste generation overlap between the towns. However, between the suburbs, the respondents from households in the affluent suburbs pointed that they were mainly generating and disposing food waste because they did not think it is an issue. Excessive cooking and food expiring before being consumed were found to be the most common reasons for food waste generation and disposal among households in the low and middle-income suburbs. The times which households are likely to generate more food waste were investigated. Nonetheless, only a few households indicated that there were times that they generated and disposed more food in the bins. The most cited times in the affluent suburbs were during Christmas (54%) and in summer (41%). Festive season (65%) and traditional ceremonies (37%) were the most cited times in the middle-income suburbs, while festive season (46%) and the summer season (36%) were the most cites among households in the low- income suburbs. The dimensions of shopping and household food waste behaviour is reflected in the types and quantities of food waste generated. The results reveal that vegetables were the most wasted food type in Cradock (26%) and in Middelburg (30%), while tinned food and dairy were the least discarded food types in both study towns with no significant differences in proportions of households discarding all six food types. One of the key results is that the average self-reported and weighed food waste generated per capita per annum for the two towns was 23.40±47.20 and 202.60±128.30 kg/capita/year, respectively as compared to the estimated 6-11 kg per annum in sub-Saharan Africa and South and Southeast Asia. Between the towns, Cradock generated more food waste (5.05±2.68 kg) than those in Middleburg (3.84±2.59 kg) in the previous 48 hours. It was also evident that each household and each person in Cradock generated more food waste at breakfast and the least at lunch, while in Middelburg the highest average amount of food waste generated was observed at supper and the least at lunch. The results indicate that household size and employment status were negatively correlated to food waste generation, while wealth status and gender were positively correlated to food waste generation. Majority of households (74% in Cradock and 73% in Middelburg) had no household food waste minimisation strategies implemented. The most cited strategies in place were cooking less frequently, cooking small portions and chopping and freezing vegetables as an anti-food waste strategy. Worth noting is that the small proportion of households with strategies in place are faced with a challenge of some household members showing unwillingness to effectively implement the strategies. The results also reveal that children wasted more food than adults, particularly girls. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2022

Majority of households (74% in Cradock and 73% in Middelburg) had no household food waste minimisation strategies implemented. The most cited strategies in place were cooking less frequently, cooking small portions and chopping and freezing vegetables as an anti-food waste strategy. Worth noting is that the small proportion of households with strategies in place are faced with a challenge of some household members showing unwillingness to effectively implement the strategies. The results also reveal that children wasted more food than adults, particularly girls. , Thesis (MSc) -- Faculty of Science, Environmental Science, 2022

- Description: The main objective of this study was to determine the extent and nature of value that HRM digitalisation can add to the South African workplace. Digitalisation is a product of 4IR, which refers to the process of leveraging and applying 4IR technologies within organisational operations, including HRM, with the aim of optimising business processes. HRM digitalisation refers to the adoption and application of digital HRM technologies of the 4IR in the conduct of HRM practices, policies, activities and transactions to optimise the HRM function. Due to a shortage of studies that shed light on the value contributed by HRM digitalisation in the workplace, a need arises to determine the extent and nature of this value and the strategies needed to unlock this potential in the context of the 4IR. Moreover, in most South African (SA) organisations, there has been a lack of a fully integrated approach to digital HRM. Thus, this study aims at exploring HRM digitalisation and the value it contributes to South African organisations, with the expectation of developing an articulated and integrative HRM digital strategy for South African organisations. This study was accomplished by means of a literature and an empirical study. The literature study provided theoretical information related to challenges and opportunities introduced by the 4IR in the world of work, with specific reference to the South African workplace and which therefore impact HRM and necessitate the need for digitalisation of HRM. In addition, the following were explored: HRM Digital Strategies that could be adopted and add value in the South African workplace; the extent and nature of that value; the challenges probably encountered in doing so and possible means to overcome the challenges. The discussion led to the development of a hypothetical, theoretical model of HRM digitalisation in the South African workplace. The hypothetical model was used as the basis for the development of a measuring instrument used to collect empirical data for this study. The empirical study used the online questionnaire survey as the data collection instrument that measured the extent and nature of value that various HRM Digital Strategies could vii | P a g e add to the South African workplace; perceived value and hard evidence of the impact of HRM digitalisation; and the extent and nature of challenges associated with the Adoption of HRM Digital Strategies across the HR value chain. The online survey questionnaire was administered to HR directors, HR managers, HR practitioners and line managers who worked in the automotive manufacturing industry in the municipalities of Nelson Mandela Bay in Port Elizabeth and Buffalo City in East London in the Eastern Cape Province of South Africa. A non-probability sampling procedure which comprised a combination of purposive and snowball sampling methods was used to select participants for the study (n = 312). The results from the empirical study, computed using Exploratory Factor Analysis (EFA), descriptive statistics and inferential statistics (such as paired-sample t-tests, Pearson’s product moment correlation and regression analysis) showed that organisations in South Africa had invested and adopted more of Digital Talent and Digital Media strategies and less of Digital Org (Design & Culture) and Digital ERM HRM strategies across the HR value chain and as a result, had gained more value at relational level, followed by that at operational level. They gained the least value at transformational level. It was therefore revealed that if HRM professionals, managers and leaders within organisations want to boost the contribution of the HRM function towards achieving the strategic goals of the organisation (transformational level), digitalising the function is one of the best ways. They can achieve this by investing more of HRM Digital Strategies related to Digital Org (Design & Culture), followed by Digital Talent and Digital ERM strategies. Challenges related to the adoption of digital strategies across the HR value chain were only found to negatively influence Digital Org (Design & Culture) and Digital ERM strategies, whereas Digital Talent and Digital Media strategies were not negatively influenced. Based on the literature and empirical results of this study, an integrative HRM digitalisation model was designed to provide a framework approach for implementing HRM digitalisation in South African organisations. , Thesis (PhD) -- Faculty of Business and Economic science, 2022

- Description: Improved healthcare enables people to live longer and thus spend more time in retirement than ever before. In addition, South Africans have a low propensity to save and invest, resulting in the danger of them living longer than their finances permit. The financial planning industry is also experiencing the technological automation of many transactional services, which could make the “traditional” role of financial planners redundant. Furthermore, financial planning businesses are prone to failure, especially during the start-up phase. As such, appropriate business management strategies, especially those relating to human capital, are critical to facilitate the effective development of financial planning businesses and which will enable financial planners to better engage with existing and new clients, resulting in creating more value creation for their financial planning businesses and benefitting the South African economy at large. It is a well-known fact that people who engage with a financial planner report better outcomes in terms of financial and general well-being than those who approach financial planning with a “do-it-yourself” mindset, which further emphasises why the longevity of financial planning businesses in South Africa is important. To date, however, limited academic research has been conducted on the influence of financial planners’ human capital on value creation in their financial planning businesses. Furthermore, although research in the financial planning field is growing, previous research has mostly focused on areas pertaining to financial advice, the financial planning process and products used in financial planning, rather than on the creation of profitable businesses or on how to create value within these businesses. Against this background, the primary objective of this study is to investigate the influence of selected Human capitals of financial planners on value creation in South African financial planning businesses. More specifically, the study investigates the influence of the independent variables of Social capital (measured individually in terms of its sub-categories, Relational social capital, Network social capital and Cognitive social capital), Entrepreneurial capital and Psychological capital on the dependent variables (Perceived financial value creation and Perceived non-financial value creation). v Based on the primary objective and research questions of the study, as well as the assumptions of the researcher, this study was positioned in the positivistic research paradigm and a deductive approach to theory development was adopted. The purpose of the study was explanatory, and a mono-method, quantitative methodological approach was selected. A survey strategy using a cross-sectional approach was undertaken and a measuring instrument in the form of an online questionnaire was developed to gather the data required. After undertaking a pilot study, the electronic link to the covering letter and online questionnaire was sent to potential respondents identified through the convenience and snowball sampling techniques. The data collection yielded 360 usable responses from South African financial planners on which to undertake the statistical analysis. Data analysis ensued to investigate the hypothesised relationships between the independent and dependent variables. A confirmatory factor analysis (CFA) was performed on each of the factors that made up the measurement models. These CFAs were compared to the various goodness-of-fit indices and then validity and reliability assessments of the factors were conducted to confirm the suitability of the measuring instrument. Thereafter, Cronbach’s alpha coefficients, average variance extracted (AVE) estimates and squared correlations between the constructs were reported. The hypothesised model was confirmed based on these analyses. Descriptive statistics and correlation results on the dependent and independent variables were then reported. Structural equation modelling (SEM) was used as the statistical technique to test the significance of the hypothesised direct and moderating relationships. The results confirmed a direct, significant relationship between all the independent variables, namely, Social capital (measured individually in terms of its sub-categories, Relational social capital, Network social capital and Cognitive social capital), Entrepreneurial capital and Psychological capital, and the dependent variables (Perceived financial value creation and Perceived non-financial value creation). Regarding the hypothesised moderating influence of Social capital on the relationships between the independent variables Entrepreneurial capital and Psychological capital, and the dependent variables, it was found that only Relational social capital and Network social capital moderated the relationship between Psychological capital and Perceived financial value creation. vi This study has contributed to the body of knowledge of financial planning in general, as well as how the human capital of financial planners influences both financial and non-financial value creation in financial planning businesses. Practical recommendations were made that could enhance financial planners’ value creation in financial planning businesses, which, in turn, would influence the sustainability of these important businesses. , Thesis (PhD) -- Faculty of Business and Economic science, 2022

- 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: This thesis centres itself around an investigation into the representations of the relationship between intimacies and ideas of romance, love, desire, and vulnerability in male relationships. The premise for this body of work was sparked by my own observations on the conflation of sex and intimacy in representations of queer male love—particularly (but not exclusively) in mainstream film and media. Whilst intimacy and sex are not unrelated, the over-emphasis on the physical when trying to represent the connection between two men led me to consider other ways in which a relationship or special connection could be gestured towards — through other kinds of signifiers that last longer than physical contact and point to the importance of a particular connection. In the introduction, I consider my own experiences as a closeted queer teen when contemplating representations of queer relationships in mainstream media. I explore several studies by gender and film theorists who consider reasons and modes in which the representations of queer intimacies on-screen are distorted to favour a presumed heterosexual audience. In the first chapter, I discuss two potential means by which to relay a more complex emotional state via the use of narrative signifiers. I examine T.S. Eliot's (1919) theory on the objective correlative in narratives as a means to explore the emotional state of a character through metaphors which open up the reading rather than illustrating it through dialogue or direct speech. I then explore Susan Stewart's (1992) ideas on souvenirs of personal experience. In Chapter Two, I conduct a close reading of three mainstream films, which employ such signifiers in the attempt to share more complex representations of queer male intimacies through well-developed storylines and characters. The films Brokeback Mountain (2006), Moonlight (2016), and Call Me by Your Name (2017) have been selected based on their use of the objective correlative and souvenirs as plot devices (rather than exclusively physical intimacy) to demonstrate the emotional resonance between characters. The third and final chapter explores my own use of objective correlatives and souvenirs as symbolic, narrative devices in my practical body of work: an online garden of remembrance. My practical work focuses largely on the process of creation of these intimacy objects (the objective correlative or the souvenir) through an investigation into my own poetry, which details my experiences of intimacies with other men, specifically where vulnerability and secrecy played a large role. , Thesis (MFA) -- Faculty of Humanities, Fine Arts, 2022

- Description: Isahluko sokuqala sixoxa ngengxaki yophando esi siseko kolu phando, nemibuzo yophando kunye neenjongo zokuba isifundo esikhoyo sifuna ukufezekisa ntoni. Ngokunxulumene nengxaki ephandwayo, esi sahluko sigxile kuphononongo loncwadi ukuze kuhlolwe ubudlelwane phakathi kolwimi lokufundisa kunye nempumelelo yabafundi kwiBanga le-12 kwisifundo seJiyografi. Ukuhlolwa koncwadi kuthathwe kwimigaqo-nkqubo yokufundisa kunye neethiyori zophuhliso lokuqonda nenkcubeko. Inkqubo yeethiyori ezikhethiweyo zisetyenziselwa ukwenza ingqiqo yokuba ulwimi lokufundisa luba nefuthe njani ekufundiseni nasekukhuleni kwengqondo nokuqiqa komfundi. Ngophononongo loncwadi, umphandi unqwenela ukufumanisa ubunzima abahlangabezana nabo abafundi ekufundeni iJiyografi ngolwimi lwesiNgesi kwiBanga leshumi elinesibini. Olu phando luza kuphonononga nzulu ifuthe leelwimi kwimpumelelo yabafundi kwisifundo seJiyografi kubafundi besigaba seshumi elinambini kujoliswe kwindlela abaphumelela ngayo kwiimviwo zokuphela konyaka.Olu phando luza kujongwa kwizikolo ezibini kwiphondo leMpuma Koloni kwisithili saseMonti phakathi kweminyaka wama-2016 ukuya kuma-2018.Ngokophando esele lwenziwe, abafundi abalwimi lwabo lwasekhaya lusisiXhosa kufanele ukuba bafundiswa ngolwimi lwabo abazikhethele lona ukutsho oko isiXhosa kwaye bavavanywe kwangalo. Oku akunjalo njengoko amaphepha abo ovavanyo engolwimi lwesiNgesi, lwimi olo olufika lubabeke phantsi konxinzelelo olukhulu olubenza bangabinakho ukuzithemba nokuziva bekhululekile xa bephendula imibuzo emagumbini okufundela. Umphandi olu luvo uluseka ngengxelo ayifumene kumaxwebhu eSebe lezeMfundo (2018 NSC Chief Markers Report) yesifundo seJiyografi iphepha lokuqala. , Thesis (MA) -- Faculty of Humanities, School of Language, Media and Communication, 2022

Illicit economic activities of irregular warfare groups: A case study of the Islamic state (is) and the response of the international community

- Description: This study is about the illicit economic activities (especially oil smuggling) of the Islamic State (IS) and the response of the international community (UNSC, national governments, and nonstate actors) from 2014 until 2021. The context of the study is the ongoing Syrian civil war and the IS Caliphate, in Syria and Iraq. Through Critical Terrorism Studies (CTS) as a critical approach to terrorism studies the study investigates the contribution of oil smuggling to the military strength of the IS. The study evaluates the effectuality of the force-based counterterrorism strategies deployed by the international community against the IS. Ultimately, the study develops a CTS-oriented approach to understanding how actions can be taken to counteract similar global terror threats in the future. The IS is a global Salafi Islamic irregular warfare group that originates from the Middle East. In June 2014, the IS proclaimed a Caliphate (Islamic state) in the Middle East, only for it to be dismantled by the US-led coalition forces and local Kurdish forces in 2019. The study applies qualitative documentary research. It utilises both primary and secondary sources. The research findings reveal that oil smuggling was a significant source of income for the IS only for a short period of time (early 2014 till late 2015). However, few other economic activities of the IS were consistent in generating income throughout. Furthermore, no evidence suggests that illicit oil trade profits of the IS were used to strengthen the military capacity of the organization. Instead, data revealed that the IS relied heavily on military weapons seized from its opponents on the battlefield including weapons from the US that were meant for the local Kurdish forces. The findings further reveal that while military force (mainly airstrikes) by the international community significantly reduced IS’s oil production and smuggling activities, they at the same time also exacerbated social challenges such as the refugee crisis, damage to infrastructure and loss of innocent civilian lives. , Thesis (MA) -- Faculty of Humanities, History and Political Studies , 2022
