- Description: This treatise is a study that concerns itself with the exploration into an international convention and exhibition centre for Namibia and the appropriate architectural response in terms of its program and context. Typically convention centres tend to be large introverted buildings, lacking an engagement with its surroundings and a true sense of place. The study will aim to capture the unique essence, identity, and the spirit of place, which will be key to the development of the brief and expression of the building. The investigation and analysis will bring about a design proposal that aims to respond to the relevant issues and topic of the treatise in a meaningful, sensible, and appropriate architectural manner.

Land reform and rural livelihoods of evicted farm workers: a case study of Radway Green Farm Project

- Description: The land issue has remained a contentious one more than two decades into a democratic South Africa. With the dispossession of the indigenous people from their land stretching back as far as 1913, eviction of farm workers and farm dwellers has increased tremendously even in the post-Apartheid era. Thus, the main goal of this study is to analyse the impact of the eviction on the Radway Green farm workers’ community and to examine the factors affecting the generation of livelihood activities in their new settlement. In doing so, I used the Sustainable Rural Livelihoods Approach (SRLA) as my theoretical framework as it conceptually grounds my area of study. It was employed to analyse data gathered from the field through in-depth interviews, focus groups, key informant interviews and descriptive observation of the case study. The centrality of the SRLA concept is on rural development, poverty eradication and the ability or sustainability of the vulnerable and poor to cope with stresses and shocks as they make a living (Scoones, 1998: 5). In that regard, the theoretical framework became an important cornerstone in analysing the impact of eviction of the Radway Green farm workers’ community and examining the factors affecting the generation of livelihoods activities in their new settlement. To analyse the research findings, various themes were utilised Forced Evictions and Resettlement; Eviction or Displacement; The Struggles of Recreating Livelihoods; The Need for Security of Land Tenure and Access to Infrastructure. Under these themes, the study revealed how the eviction was detrimental to the livelihoods of the farm workers and farm dwellers as they lost the land that was a primary source for the construction of their livelihoods. They lost employment, homes, agricultural land for food security and natural resources, social and family structures and most importantly cultural disruption. It is well documented that the rural poor who constitute the farm workers and the farm dwellers are some of the vulnerable people who need constant governmental support through the promulgation of laws that protect them and assist in livelihood construction. Thus, this study also served to examine how the evicted workers and their families have settled into their new homes and how they, in conjunction with the Department of Rural Development and Land Reform and any other government agencies are faring in terms of the establishment of income generating projects for their livelihoods at the new settlement.

An in depth study was undertaken to review the Mhlontlo LED strategy using document analysis to look at the relevance of the strategy to the current economic activities, its alignment to the current national and provincial development plans. The LED Strategy is no longer aligned to the current development plan, the National Development Plan. It was clear during the study that the Mhlontlo LED Strategy was never understood by both councilors and officials, not working in the LED department and that led to the neglect of the LED strategy in the development plans of the various departments in the municipality. This had adversely compromised the development corridors identified in the LED strategy. The recommendation is that the LED Strategy be holistically reviewed, so that it can be aligned with the National Development Plan, the Mhlontlo Local Municipality Integrated Development Plan 2017-2021 and other municipal documents. Both Mhlontlo municipality councilors and officials should be trained on the role of the LED strategy in development taking place in the municipality.

- Description: Performance management and development in the South African Public Service is a critical aspect that engenders officials and management to be committed to the provision of efficient and effective service delivery. The Public Service Regulations (2001) as amended requires all spheres of government to develop and implement policy parameters that address measurable service delivery aligned to their strategic functions. The imperatives of these policy parameters allow employees’ performance with notch increments. The National Department of Sport and Recreation South Africa (SRSA) developed a performance management system that links Employee Performance Management and Development System (EPMDS) at salary levels 5 – 12 to notch increments and Human Resource Development programmes. This system aims to achieve consideration of the desired outputs; meaning the delivery of work required, which is emphasised in the setting of objectives and looking at the necessary inputs; meaning the knowledge, skills, training and resources needed, which are considered in the appraisal and reviewing of the progress that was made. The performance of Sport and Recreation South Africa has not been commensurate with the aims and objectives of the EPMDS system, as the results are not yielding the best outcome on this system. This study sought to investigate whether the EPMDS contributes to improve performance of the employees and that of the entire organisation in SRSA. It would examine whether the employees do get feedback on their performance after the performance assessment period. The study would establish whether those employees who under-performed do get remedial interventions like training, coaching, mentoring and development on the competencies they lack; so that their performance is improved. The study also sought to determined the perception of the employees regarding the effectiveness of the Performance Management and Development System in SRSA Knowledge of employees' perceptions of the performance management system will assist management to implement such a system more effectively. The findings of this study indicate that managers use performance management as a tool to control and discipline subordinates, whilst subordinates use performance management as a means of getting extra money through performance bonuses. This could be the reason that performance assessment period is viewed as a period of high tension between supervisors and subordinates. The main recommendation on the basis of this finding is that there should be a regular and thorough training of officials at all levels within SRSA about the EPMDS and how it influences productivity. Other additional recommendations include, inter alia, that the identification of gaps on unsatisfactory performance should be made immediately after each performance period. Remedial interventions to address those gaps like training, retraining, coaching and counselling should be formulated, agreed upon and implemented.

- Description: This thesis contributes to the history of the information and propaganda policy and practice of the government of the Federation of Rhodesia and Nyasaland by examining this government's pro-Federation print and radio propaganda for Africans in the Federation. Using a multi-theoretical approach, it analyses the character of this propaganda, highlighting its main methods and themes as well as the policy considerations, plus political and economic circumstances that gave rise to it. It also discusses how Africans in the Federation reacted to this propaganda and assesses its effectiveness in gaining the support of these Africans for Federation and the policies of the Federal government. The thesis argues that Federal government propaganda aimed at gaining the support of Africans for Federation was predominantly panic-driven propaganda and was the product of an information panic that lay at the heart of the very idea of Federation itself. This information panic arose out of the Federal government's belated recognition of the strength of African opposition to Federation and of how this opposition seriously threatened the continued survival of the Federation. It is also argued that this panic-driven pro-Federation propaganda elicited largely hostile reactions from the majority of Africans in the Federation and failed to persuade them to support Federation.

- Description: Significant changes have occurred in South Africa during the past decades in household saving and borrowing behaviour. The rapid increase in South Africa’s household debt over the last twenty years has been an international phenomenon. In most countries, household debt increased from the 1990s until the crisis of 2007–2008 before stabilising due to a recession and deleveraging. The study used an ARDL model to investigate the determinants of household debt in South Africa. Pairwise regression is used to select the most relevant variables affecting household regression in the country. The results of the study showed that consumer confidence, the bond market index and the vulnerability index have a positive effect on household debt. As consumers' faith in the performance of the economy increases, household debt also increases as expected, reflecting consumers' belief in increased future wealth. The positive influence of the vulnerability index suggests that households tend to resort to borrowing to smooth consumption when incomes and other related factors decline. It is recommended that national policy should tighten regulations around access to unsecured credit to minimise the stress on already vulnerable households.

The Department of Correctional Services is committed to providing a needs-based approach to all offenders including female offenders, who are recognised as special category offenders. The study made use of a qualitative approach and the research design was based on a case study. Data was gathered by means of in-depth interviews with nineteen participants at the Worcester Female Correctional Centre. A literature study was conducted on the importance of strengthening and supporting the mother/child relationship during maternal incarceration, and the challenges experienced in maintaining the mother/child relationship. Thereafter, an empirical exploration was done and the results were purposefully processed and analysed. Through processing and analysing the results, the researcher was able to derive certain conclusions and make recommendations, which are presented in Chapter Five of this thesis. The most important conclusion resulting from the research study is the importance of the maintenance of the mother/child relationship during maternal incarceration. The study made various recommendations that the Department of Correctional Services can utilise to improve its services to female offenders, especially those with children.

- Description: The intention of this research was to explore and discuss the importance of the mother/child relationship during maternal incarceration for aiding a successful reunificationupon release. The Department of Correctional Services is committed to providing a needs-based approach to all offenders including female offenders, who are recognised as special category offenders. The study made use of a qualitative approach and the research design was based on a case study. Data was gathered by means of in-depth interviews with nineteen participants at the Worcester Female Correctional Centre. A literature study was conducted on the importance of strengthening and supporting the mother/child relationship during maternal incarceration, and the challenges experienced in maintaining the mother/child relationship. Thereafter, an empirical exploration was done and the results were purposefully processed and analysed. Through processing and analysing the results, the researcher was able to derive certain conclusions and make recommendations, which are presented in Chapter Five of this thesis. The most important conclusion resulting from the research study is the importance of the maintenance of the mother/child relationship during maternal incarceration. The study made various recommendations that the Department of Correctional Services can utilise to improve its services to female offenders, especially those with children.

- Description: The distribution of the platinum group element (PGE), in the Merensky Reef was characterized by, first determining the occurrence of the platinum group minerals (PGM), then by establishing the PGE concentration in the base metal sulphides (BMS) associated with the PGE mineralization in the Merensky Reef from selected borehole intersections, at the Two Rivers (TRP) and Modikwa Platinum Mines in the Eastern Bushveld Complex. A mineral liberation analyser (MLA) was then used to identify the PGM phases; their silicate and base metal associations; and their grain size distribution. Electron microprobe quantitative analysis and mapping were then used to determine the compositional variation of the PGM and the PGE elemental distribution in the BMS, respectively. The study showed that the BMS including pyrrhotite, pentlandite, and chalcopyrite were the principal sulphides, where pyrrhotite was most prominent with minor quantities of pyrite. Orthopyroxene, clinopyroxene and plagioclase were the most abundant primary silicate minerals identified, while secondary silicates identified included talc, serpentine and amphibole. Platinum group minerals showed three distinct groups with respect to the mineralogical association with the PGE; (i) BMS association; (ii) chromite association; and (iii) silicate association. Of the BMS, chalcopyrite showed the most dominant association with the PGMs. All samples from both mines exhibited a wide range of PGMs, including maslovite, braggite, cooperate, laurite and PGE alloys such as ferroplatinum as well as other unidentified platinum and palladium sulphides, arsenides and bismuthides, while gold was present as electrum. The PGMs ranged in size from less than a micron to about 125 microns with an average of 20 microns. The close association of PGM with BMS along the margins of sulphides indicates that the PGMs were derived from the sulphide melt. PGE distribution in the sulphides at Modikwa showed pentlandite contained the highest concentrations of palladium (up to 379 ppm) and chalcopyrite hosting the highest rhodium concentrations (up to 793 ppm). Samples from Two Rivers revealed pentlandite as the principal host to both palladium and rhodium, with concentrations reaching up to 695 and 930 ppm, respectively. Magnetite at both Modikwa and Two Rivers showed significant rhodium content, reaching up to 982 and 930 ppm, respectively. The pyrrhotite compared to other sulphides contained all the elements found in the platinum group (PPGE), namely, platinum, palladium and rhodium, with all the platinum identified found in the pyrrhotite. The concentrations for the iridium group (IPGE) namely, iridium, osmium, and ruthenium were below the detection limit. The PGE mineralization in the stratigraphy varied within each mine. The mineralization revealed top loading in the central sector (Modikwa) and bottom loading in the southern sector (Two Rivers). The sequence of the Merensky Reef at the two sectors of the Eastern Bushveld Complex showed a remarkable similarity in their mineralogy suggesting that these two sectors were formed from the same liquid or formed simultaneously within a single magma chamber; however the PGE distribution within the stratigraphy may have been controlled by the presence of cumulate sulphides.

- Description: South Africa is endowed with a well-developed and regulated financial system which compares favourably with those of other developed economies. Therefore the financial sector is intended to play a significant role in supporting the real economy, by enhancing trade and stimulating economic growth and development. Despite the existence of a stable, developed and well-regulated financial sector, the South African economy has experienced current account deficits for the past 10 years and economic growth rates have mostly trailed behind the targets prescribed by the socio-economic programs formulated and implemented since 1994. To solve the trade – financial development – economic growth nexus problem, most studies have focused on other countries while research studies on South Africa did not explicitly investigate the trade – financial development – economic growth triangle, the linkage which failed to yield the desired outcome for South Africa’s post 1994 era.Therefore, this study employs Cointegration Vector Autoregressive (CVAR) methodology to investigate the relationship between trade, financial development and economic growth in South Africa. The unit root test revealed that the variables considered in the study are I(1) variables and the Johansen cointegration test justified the existence of a long run relationship among the variables. The empirical findings indicate that imports and financial development are positively related to exports whilst economic growth is negatively related to exports. The VAR Ganger causality test has shown that there is a uni-directional causality running from financial development to economic growth, exports and imports and that imports Granger cause exports. The results of this study form the basis for further investigation into the non-performance of exports and economic growth in the nexus. The research study opens up new policy insights by suggesting that financial policy can be used to be more supportive to the production of intermediate and finished products destined for both international and domestic markets.

- Description: Hostile school environments are a cause of concern and a perennial international educational problem. The UNICEF’s Child-Friendly Schools (CFS) approach is an international intervention meant to safeguard learners against hostile school environments. The CFS approach mandates schools to offer learners environments and conditions that uphold children’s rights and enhance their development to full potential. The purpose of this mixed methods research study, employing a concurrent triangulation design, was to explore the role of teachers in the promotion of CFS environments. Holsti’s (1970) role theory formed the theoretical framework of this study. The research questions focused on teachers’ understanding of the CFS concept, support offered, strategies employed, challenges encountered, and the implications for teacher professional development. The data collection methods were questionnaires, in-depth interviews, and document analysis with school heads, teachers and learners in the seven government urban secondary schools in Mutare district of Manicaland province in Zimbabwe. Quantitative and qualitative data were independently analysed and merged at the interpretation stage through triangulation of results. Major findings reveal that teachers have poor understanding of the CFS concept, are offered moderate support, occasionally employ viable strategies, and are hindered by various factors in the process of promoting CFS environments. The study’s implications for teacher professional development are rooted in identifying sustainable approaches that adequately equip teachers with relevant information, skills and attitudes that ensure the promotion of CFS environments.

- Description: Despite the importance of retirement planning, many South Africans have been documented as reaching retirement age without adequate retirement funding. A vast amount of research has been conducted on how proper retirement planning can be beneficial for individuals; however, there has been a lack of attention given to researching the retirement planning of black individuals in South Africa. Thus, the primary objective of this study was to identify, investigate and empirically test which factors influence retirement planning, and which aspects of retirement planning influence the retirement funding adequacy of black individuals. After a comprehensive literature review was undertaken on the factors influencing the retirement planning and retirement funding adequacy of individuals, the following independent variables were identified as influencing the mediating variable (Aspects of retirement planning) and the dependent variable (Retirement funding adequacy) in this study: • Financial literacy; • The role of the financial planner; • Family support structure; and • Health status. These independent variables were selected to construct a hypothesised model and research hypotheses, as they have been identified as the prominent factors that influence the retirement planning of black South Africans. Furthermore, these independent variables were used in determining whether they have an influence on the Aspects of retirement planning (incorporating Retirement provisions, Retirement attitudes and Retirement intentions) and, ultimately, improve the Retirement funding adequacy of individuals. In order to establish the influence of the aspects of retirement planning on the retirement funding adequacy of individuals, an empirical investigation was undertaken. A measuring instrument, in the form of a questionnaire, was compiled from secondary literature sources. The respondents were identified though a mixed sampling approach, whereby stratified sampling and convenience sampling were used to attain 441 usable questionnaires that were subjected to statistical analyses. Descriptive statistics, in the form of frequency distributions, were used to summarise Section A and Section B of the measuring instrument. The validity and reliability of the measuring instrument were confirmed by means of exploratory factor analyses (EFA), and Cronbach’s alpha coefficients were also calculated for this purpose. As a result of conducting the EFA, two independent variables (Family support structure and Health status) loaded together, and the factor was renamed accordingly. From the EFA, the independent variables that emerged were The role of the financial planner, Family, health, and financial well-being, and Financial literacy. Furthermore, the EFA revealed that three mediating variables emerged from the mediating variable Aspects of retirement planning. These three mediating variables were consequently named Retirement intentions, Retirement attitudes, and Retirement provisions. There were no eliminated variables in this study. Based on the results of the EFA, some of the definitions of the variables were adapted. Consequently, the hypothesised model and its research hypotheses were adapted to reflect the results of the EFA. The results of the Cronbach’s alphas calculated reported that all the measuring scales used in the questionnaire of the study were reliable. Furthermore, descriptive statistics were also calculated to summarise the sample data, and Pearson’s product moment correlations were calculated to establish the correlations between all the variables used in this study. A multiple regression analysis was used to investigate the influence of the various independent variables on the mediating variables and the dependent variable. Furthermore, structural equation modelling (SEM) was used as the main statistical procedure to test for mediation in the study. SEM was also used to assess and confirm the results of the multiple regression analyses. Based on the results of the multiple regression analyses and SEM, the hypothesised relationships of the study were accepted or rejected. Additionally, the results of SEM revealed that the revised model of the study displayed acceptable model fit. To conclude the empirical investigation, t-tests and an analysis of variance (ANOVA) tests were performed to assess whether the respondents’ perceptions of the variables used in the study differed as a result of the respondents’ demographic information. Furthermore, to establish significant differences between individual mean scores, post-hoc Tukey tests were calculated, and practical significance was assessed by calculating Cohen’s d values. The main empirical results of the study found that statistically significant relationships exist between the independent variables The role of the financial planner and Family, health, and financial well-being, and the mediating variable Retirement intentions. Furthermore, a significant relationship was found between the independent variable Financial literacy and the mediating variable Retirement attitudes. Other significant relationships were present between all the independent variables The role of the financial planner, Family, health, and financial well-being and Financial literacy, and the mediating variable Retirement provisions. The study also established statistically significant relationships between the mediating variables Retirement attitudes and Retirement provisions and the dependent variable Retirement funding adequacy. Statistically significant relationships were also present between the independent variables Family, health, and financial well-being and Financial literacy and the dependent variable Retirement funding adequacy. This study has added to the limited amount of academic literature in the field of retirement planning in South Africa. Through the hypothesised model developed in this study, a significant contribution has been made towards investigating the factors that influence the retirement planning and retirement funding adequacy of black individuals residing in South Africa. This study presents recommendations to black individuals on practical strategies that could help to improve their retirement planning and retirement funding adequacy. Furthermore, suggestions are presented to financial planners and financial institutions, in order to assist black individuals or potential clients to improve their retirement planning and to help ensure that individuals are financially independent when they reach retirement age. It is recommended that financial institutions provide financial products/services that will cater to black South Africans.

- Description: The purpose of this study was to determine whether gifted pupils can master an enriched advanced level curriculum in mathematics using self-regulated learning strategies. A mathematics curriculum for class five primary school learners in Nigeria was developed for this study. An empirical study was conducted on primary five pupils who were seen to be significantly gifted in mathematics. The study employed the quantitative method of research, that is, the true experimental research. The pre-test, post-test control group design was used. Sixty gifted pupils who participated in a mathematics enrichment programme (MEP) were assigned into two groups of the control group and experimental group with thirty pupils forming each group. The control group was exposed to direct teaching (DT) while the experimental group used self-regulated learning (SRL) strategies. Four teachers served as facilitators in the MEP. The teaching and learning activities were carried out at a higher cognitive level as opposed to the regular curriculum, ensuring that the contents of the MEP were enriched and accelerated. Pupils in both the experimental group and the control group were administered a pre-test, problem-solving exercises, and post-test. These pupils also completed an attitudinal questionnaire to provide feedback about the MEP. The empirical results show that gifted pupils in primary five are capable of self-regulating their own learning through self-monitoring, self-evaluation, and self-reinforcement. The empirical results also show that there is a significant relationship between self-regulated learning, gifted learners, and an enriched advanced level differentiated curriculum as a realistic alternative to the present regular curriculum for gifted pupils in the mainstream of education. The findings further show that the lack of differentiation of instruction, lack of facilities such as libraries, media centres, and support materials contributes to low achievement of gifted pupils. Furthermore, the findings show that pupils were challenged and motivated with the MEP to the extent that they were engaged to think divergently and applied their metacognitive skills in finding solutions to mathematical problems. Therefore, the findings of this study could have significant implications for the future direction of gifted primary school education as well as teacher education. This study has made a significant contribution to the existing body of knowledge for implementing an enriched advanced level curriculum using SRL strategies for mathematically gifted pupils in the mainstream of primary school education.

The empirical results show that gifted pupils in primary five are capable of self-regulating their own learning through self-monitoring, self-evaluation, and self-reinforcement. The empirical results also show that there is a significant relationship between self-regulated learning, gifted learners, and an enriched advanced level differentiated curriculum as a realistic alternative to the present regular curriculum for gifted pupils in the mainstream of education. The findings further show that the lack of differentiation of instruction, lack of facilities such as libraries, media centres, and support materials contributes to low achievement of gifted pupils. Furthermore, the findings show that pupils were challenged and motivated with the MEP to the extent that they were engaged to think divergently and applied their metacognitive skills in finding solutions to mathematical problems. Therefore, the findings of this study could have significant implications for the future direction of gifted primary school education as well as teacher education. This study has made a significant contribution to the existing body of knowledge for implementing an enriched advanced level curriculum using SRL strategies for mathematically gifted pupils in the mainstream of primary school education.

- Description: Biological control of invasive alien plant (IAP) species is the use of introduced, highly selective natural enemies (usually herbivorous arthropods or pathogens) to control plants. It has been used in 130 countries as a valuable tool for the control of IAP species, with a total of over 550 biological control agents having been released (Winston et al. 2014). The benefits of biological control to natural ecosystems are significant (Van Driesch et al. 2010), with some specific examples of threatened indigenous species being protected by the action of biological control agents (Barton et al. 2007; Meyer, Fourdrigniez & Taputuarai 2011). Detailed analyses of programmes on biological control of IAPs have also clearly indicated that the risks of non-target effects from biological control agents are minimal (Fowler, Syrett & Hill 2000; Funasaki et al. 1988; Moran & Hoffmann 2015; Paynter et al. 2004; Pemberton 2000; Suckling & Sforza 2014). Less than 1% of all the agents released have a negative impact on non-target plant populations, and those that do could have been predicted to do so, and would not be released today (Suckling & Sforza 2014).
