  • Description: A study of the available literature on Workplace Well-being, Positive Organisational Capital and Workplace Trust revealed that enormous potential existed for further research. This is a relatively new field with limited literature and research evidence available. It became very clear from the beginning that the relationships between these constructs could successfully be researched. It was therefore decided to embark on an academic research journey in order to contribute to the existing knowledge available on these constructs within the South African business scenario. This quantitative research was used to obtain more clarity about the relationships between the three constructs and to gather the responses from the research population. This research group consisted of 228 managers from the manufacturing operation of a motor vehicle production company and 224 managers from their National Dealership network. The research sample consisted of 452 managers. Three questionnaires were integrated to develop the composite Workplace Wellbeing Questionnaire and consisted of i) Workplace Well-being questionnaire developed by Parker and Hyett (2011), ii) PSYCAP Questionnaire developed by Luthans, Youssef and Avolio (2007), and iii) Workplace Trust Survey developed by Ferres (2001). The managers (n = 452) responded to a 91–item electronic questionnaire. Seven research questions were formulated and covered areas such as: The content, validity and portability of the measuring instruments; The configuration of the various constructs; Relationships between some of the variables; The effect of demographical data on the research variables and; The building of a research model. The content and the structure of the measuring instruments were assessed by means of Confirmatory Factor Analysis (CFA) and Exploratory Factor Analyses (EFA). These assessments showed that the original measuring instruments are not portable to a culture which is different to the one where they were originally developed. The relationships between the variables were determined by: Pearson product moment correlation; Multiple Regression co-efficient; ANOVA and Cohen’s d Test. The relationship between aspects of Workplace Well-being (Job satisfaction) and trust is a significant finding; so are some aspects of PSYCAP (sense of achievement and optimism) and Trust and Well-being. Trust has shown a definite relationship with Work- place well-being. A structural equation model was built to test the relationships between the elements of Workplace Well-being, PSYCAP and Workplace Trust. No satisfactory fit of the model on the data was obtained, although strong correlations between some of the variables existed. The significance of the findings of this study and the contribution that it makes to the existing theory is seen in the importance of the portability of measuring instruments. Recommendations in this regard have been made in Chapter 5. Various findings have also highlighted the relationships between Workplace Well-being, PSYCAP and Work-place Trust. The importance of future research topics has been recommended and a proposal has been made to consider a longitudinal well-being research study.

  • Description: The South African government has endeavored to provide settlement to citizens and policies have been formulated since 1994 to guide these efforts. The South African Constitution (1996, section 26) stated that everyone has the right to have access to adequate housing. Furthermore the African National Congress’s Freedom Charter (1955) made it clear that: “there shall be houses, security and comfort for all, everybody shall have the right to live where they choose, to be decently housed, and to bring up their families in comfort and security. Slums shall be demolished and new suburbs built, where all shall have transport, roads, lights, playing fields, crèches and social centers”. However, after 19 years of democracy the state of housing is still a critical issue that addresses whether development has served to further the cause of sustainable development with respect to the pillars of human settlement such as shelter, infrastructure and economic opportunities. The study was conducted in the Litchis Bay settlement in East London, Eastern Cape Province. Mixed approaches of quantitative and qualitative methods were used to solicit data. Random Sampling techniques were conducted to select the sample population. Data was captured on Excel sheets to generate graphs. Findings of the study and conclusions were drawn. Therefore when measuring the term ‘sustainable human settlement’ against the findings on RDP houses in Litchis Bay, one can conclude that sustainable human settlement is not fully absorbed in defining the sustainability of RDP houses in Litchis Bay. Moreover the majority of houses have defects, and social amenities are not easily accessible.

  • Description: Today’s production industry is faced with the challenge of maximising its resources and productivity. Tool condition monitoring (TCM) is an important diagnostic tool and if integrated in manufacturing, machining efficiency will increase as a result of reducing downtime resulting from tool failures by intensive wear. The research work presented in the study highlights the principles in tool condition monitoring and identifies acoustic emission (AE) as a reliable sensing technique for the detection of wear conditions. It reviews the importance of acoustic emission as an efficient technique and proposes a TCM model for the prediction of tool wear. The study presents a TCM framework to monitor an end-milling operation of H13 tool steel at different cutting speeds and feed rates. For this, three industrial acoustic sensors were positioned on the workpiece. The framework identifies a feature selection, extraction and conditioning process and classifies AE signals using an artificial neural network algorithm to create an autonomous system. It concludes by recognizing the mean and rms features as viable features in the identification of tool state and observes that chip coloration provides direct correlation to the temperature of machining as well as tool condition. This proposed model is aimed at creating a timing schedule for tool change in industries. This model ultimately links the rate of wear formation to characteristic AE features.

  • Description: The role of mineral beneficiation in the survival, growth, development and sustainability of a developing economy cannot be overstated. Our development as a human species has always been involvedly linked with the use of mineral resources from the stone, bronze and iron ages through the early modern eras to the present. In the current modern era, characterized by highly technological equipment, fourth industrial revolution (4IR) and new energy technologies, the role of mineral beneficiation has been elevated. Precious metals find use in the fine chemicals and petrochemicals industry, fuel cells, electrical and electronic products, medical and dentistry applications, jewellery, autocatalysts, and glass and ceramics. The markets for precious metals keep growing and the supply does not meet demand. The development of methods for recovery of metal value from feeds of mineral ore solutions, solutions of spent secondary resources and from mining wastewaters remains of great importance. Further beneficiation strategies for utilization of mineral products in other “value-added” applications are also important for the growth of the mineral markets. The usage of platinum, palladium and rhodium in the autocatalyst industry has grown significantly and this has further elevated the importance of platinum group metals (PGMs), but other areas of application of the strategic metals need to be harnessed. The four stages of beneficiation, namely, primary, secondary, tertiary and final stage, provide an opportunity to beneficiate to greater value for domestic or export use. Our own research work is engaged in several of these stages, from hydrometallurgical recovery of base metals and platinum group metals from feeds of primary mining and solutions of waste secondary resources such as spent catalytic converters and e-waste to the use of metals in “value added” products such as metalbased catalysts for the fuel industry and in metallodrugs. Examples of “value added” products include rhodium as a promoter in molybdenum sulfide as a catalyst for hydrodesulfurization of fuel oil, vanadium as a catalyst in oxidative desulfurization of fuel oil, vanadium and palladium as therapeutic agents for diabetes and cancer, respectively. Current and future work involves (i) the development of metal-selective scavengers to recover lost metal value in mining wastewaters, and (ii) the design of metal-based catalytic materials for refinement of bio-based oils to biofuel as well as for production of green LPG through hydroprocessing. Our work centres around both basic and applied chemistry towards mineral beneficiation and with a bias towards greener production.

  • Description: This study was intended to establish which polymer material is best suited as the material for bushes used in high force small oscillating angular contact applications as typically found in a large sugar mill coupling. A Tribometer as well as a designed and manufactured Bearing Testing Machine, which simulates and accelerates the wear caused in the intended application, was used to determine the wear rates and coefficients of friction for seven polymer materials. Materials were selected for their superior mechanical and thermal properties. The Tribometer was fitted with a linear reciprocating rig, so as to simulate the small oscillating movement prevalent in the intended application. Each Tribometer test ran for a duration of two hours with a frequency of 33.1 Herts and a normal loading of 40N. Bearing Testing Machine tests were done under similar constraints but with 30kN loading present on the surface of a bushes inner race. These tests had a longer duration of 24 or 48 hours or until intense wearing occurred. Initially both testing methods will be analysed independently of each other in order to try and identify a relationship between the wear rate and coefficient of friction for the different polymers. The different testing methods’ results will be compared to each other in order to establish if a correlation between the materials tested could be found.

  • Description: The purpose of this lecture is to explicate the future of financial inclusion with a focus on Africa. Understanding financial inclusion, its advantages, and its trajectory into the future sets a scene for future research and debates. Materials and methods: In preparing this lecture, I used systematic literature and bibliometric analysis complemented with field research done in two selected areas (Masvingo district in Zimbabwe and the Kirkwood area in the Eastern Cape, South Africa). Results/Findings: Results show that financial inclusion benefits poverty alleviation, job/employment creation, small business growth (through innovation and creativity), sustainability, closing inequality gaps, inclusive economic growth and development (local, national, regional, and global), closing gender gaps, and the promotion of digital finance. In other words, it creates opportunities for individuals, businesses, and economies in various ways. It also contributes to the attainment of sustainable development goals (SDGs). Globally, stakeholders such as governments, supranational organisations (the UN, the WB, the IMF, the G20) and development banks are working together to achieve financial inclusion. Alleviation or elimination of financial exclusion (FE) is the ultimate. Social implications: Financial inclusion promotes socio-economic transformation and livelihood enhancement. The unbanked, or the financially excluded, and the underbanked benefit from financial inclusion, thus allowing them access to financial services. Conclusions and recommendations: Extant literature and empirical research demonstrate the immense contribution of financial inclusion. It helps to defy the triple challenges of poverty, unemployment, and inequality. This lecture therefore recommends deliberate policy intentions by governments in developing countries to support financial inclusion to benefit the marginalised and promote the attainment of Sustainable Development Goals(SDGs). There is a need to digitise the financial systems for inclusivity. I argue that the future of financial inclusion is achieved not only by technology, but also by acceptance, behaviour, and collaboration/synergy, built around strong ecosystems. An underlying thesis is that financial inclusion benefits economies in many ways.

  • Description: All over Africa today, and particularly in the Southern Region, women in trade unions are wanting to stand up and be counted. How do we get counted, is a question we ask ourselves? Education being the unanimous answer, we were all very happy when the CTUC decided to fund a Women's Handbook project with the blessing of the Southern African Trade Union Co-ordination Council. The project was implemented in July 1986 in Harare, Zimbabwe. Sisters from Botswana, Lesotho, Swaziland, Zambia and Zimbabwe got together and our initial objectives were:- • To identify problems faced by working women in the region. • To come up with solutions to these problems. Once the main topics had been defined - i.e. women in society, in trade unions and the law, bargaining issues, health care and education for women - we set about drafting material which was to be used for pilot courses with women workers in each country. Now, nearly a year later, after having met again in Mbabane, Swaziland in March/April 1987, we have our handbook. We want this book to be used to help women educators run courses for the rank and file women workers. Here it should be noted that as women who feel we have always been discriminated against, we do not wish to carry this on by excluding our male counterparts. Therefore even though our book is aimed at women, we would welcome assistance from our brothers! Finally, we hope that this book will be instrumental in bringing about an end to our struggle for women in the labour movement.
