- Description: Work gratification and expectancies are of the utmost importance to the skilled workforce in the South African construction industry. The price paid for a demotivated workforce in this industry is very high and it leads to friction in the workplace, displeasing work outcomes and time delays. Furthermore it leads to increased incidences of theft,absenteeism and outputs that arebelow standard in terms of productivityand thequality of the work.In order to motivate the workforce in the construction industry,a day-by-day, step-by-step,hands-on approachmust be used. The aforesaid aids site managers to manage effectively and this in turn leads to an increase in production by way of enhanced productivity. Research shows that a correlationbetweenmotivation, excelling at work, improved productivity and fulfilment and expectancyexist. The reason why individuals act in a specific manner and choose not to act in a certain way can be directly linked totheirmotivation and engagement.As a member ofthe construction industry in South Africa, Stefanutti Stocks isseen as one of the leading construction groups. Employing more than 12 000 workers it has the ability to provide a wide variety of different scale projects for a host of clients in varied markets. The division concentrated on in this study is the Roads, Pipelines and Mining Services (RPM)Business Unit. The MD of the RPM Business Unit when starting at the company a few years ago came to the conclusion that in order for the RPM Business Unit to function optimally certain business inconsistencies regarding employee engagement needed to be addressed. Based on this he decided to use a consulting firm, AIM,to establish what the exact concernswere and what interventions wererequired to deal with them. ivInterventions facilitatedby AIM includedManagement Training Programmes and Workshops as well as one-on-one coaching sessions with selected individuals.The methodology used in this study was to measurethe current level of employee engagement subsequent toengagement interventionsconcludedby AIM.The approach used was the use of surveys distributed through AIM in conjunction with the RPM Business Unit’sHR Department. The surveys were distributed via Survey Monkey Software owned by the RPM Business Unit of Stefanutti Stocks. , Thesis (MBA) -- Faculty of Business and Economic Sciences, NMMU Business School, 2021

- Description: Our understanding of the evolution of dune morphology has been hampered by a lack of empirical observations of airflow behaviour over dune forms. Sand dunes intrude into the atmospheric boundary layer and convergence of streamlines results in an acceleration of airflow up the windward slopes of dunes. This study examines the airflow structure and corresponding bedform development on the windward slope of a 7 m high transverse dune on the edge of the Alexandria coastal dunefield, Algoa Bay, South Africa. The Alexandria dunefield is subjected to a trimodal wind regime, consisting of the dominant south-westerly which blows all year round, summer easterlies and winter northwesterlies. The morphology of the study dune, Dune13, is controlled by the easterlies and north-westerlies, and reverses seasonally with respect to these two winds. Seven section lines 30 m apart and normal to the dune crest were surveyed regularly over the period of a year to monitor the reversal process. Three detailed topographic surveys were also done during this period. Airflow behaviour was monitored during the year. Wind speed profiles on the windward slope of the dune were measured using 4 to 5 vertical arrays of anemometers positioned from the base of the dune to the crest on a 1 selected section line. Usually 4 to 5 anemometers were deployed in each vertical array, from a height of 6 to 10 cm above the surface, up to a height of 150 cm above the surface. Initially 8 microanemometers were available; ultimately 28 anemometers were run simultaneously. An independent weather station at an elevation of 6 m recorded the unaccelerated flow. Local gradient measurements and erosion and deposition rates were recorded along selected section lines. Strong summer easterly winds (14 m/sec at 1.4 m above the dune crest) were measured on a dune slope in the process of being transformed from a slipface to a stoss slope. The following winter, light north-westerly winds (typically B m/sec at 1.6 m above the dune crest) were measured on the new windward slope already reversed by the prevailing winter wind. Airflow data confirm the compression of airflow against the windward slope resulting in a non-logarithmic wind speed profile. Compression results in an increased shear velocity within 30 cm of the dune surface, and the dune slope is eroded. Higher up in the wind speed profile, shear velocity decreases to 0.1 m/sec. It is not known at what height the wind speed profile recovers from the intrusion of the dune into the boundary layer. High values of shear velocity (1.6 m/sec) above the rounded crestal area of the dune record the recovery of the wind speed profile from flow divergence, which is a response to the rapid reduction of dune gradient and is accompanied by deposition of sand in this region. 2 The erosion pin data act as a simple and sensitive test for changes in gradient, reflecting the dune's response to changes in the airflow regime. The shape of the dune plays a major role in determining the extent of the compression and the distribution of shear velocity up the slope. Increased shear velocity is experienced on that part of the slope which is nonaerodynamic with respect to the prevailing wind. Under unidirectional conditions, feedback between flow and form results ultimately in a slope with a curvature such that shear velocity increases systematically upslope. The survey data and erosion pin data record the reversal process as the dune achieves a new steady state during each wind season. The existence of a non-logarithmic wind speed profile makes it difficult to know what relevant measure of shear velocity is to be used in sand transport equations. Future work should include wind speed measurements within 10 cm of the surface. An ideal study modelling aeolian bedform development would utilise wind tunnel measurements, combined with field measurements such as obtained in this study, for comparison with numerical modelling. The study needs to be extended to 3-dimensional airflow measurements. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2021

- Description: The purpose of the study was to make an enquiry on the perceptions on female sterilisation adult participants, residing in Gunguluza Township, Uitenhage had. A qualitative research approach was used to collect the responses of 10 participants. These included eight women, one man and one traditional healer registered within the Traditional Healers Association of South Africa. The interviews had been semistructured with open-ended questions pre-set to help the researcher guide the conversation. Conversation analysis was the technique used to transform the information into research data that would attempt to answer the research question. The question this research attempted to answer was to form an understanding of how information and education resources provided by both Western and Traditional sources, including their availability and accessibility with regards to female sterilisation, as a form of contraception, have been understood, received and interpreted by adults residing in the research area of Gunguluza township. Gunguluza forms part of the area formally known as the Kwanobuhle 10 and Kwanobuhle 11 respectively. Some limitations, including limiting resources that resulted in only 10 participants being interviewed. The results had shown that participants had shown interest in acquiring more knowledge about female sterilisation and other reproductive health issues, in order to make informed decisions about their bodies, with contraceptive choice and use in particular. Most felt the need to engage with their partners about the choice of sterilisation largely due to the support they would need. With regard to traditional health as an alternative or interchangeable method of contraception, participants had very little knowledge of, with some expressing some importance and relevance in acquiring such knowledge, in a modern context. These findings came with sets of recommendations which placed an emphasis on the building of indigenous knowledge and its inclusion in formal spaces for open engagement and discussion. Traditional knowledge needed to be transferred from an oral to being documented into literature for future preservation and to eliminate any distortion. There was a gap for formal western medicine to collaborate or accommodate traditional medicine. The study made use of female sterilisation as a conceptual framework, with time and more future research could build and produce new theoretical understandings of the concept, from an Afrocentric context in particular. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021

- Description: The Eastern Cape is one of the poorest provinces in South Africa. The level of poverty, and lack of basic resources has given way to inadequacies in many of the services available to communities. From improper infrastructure, to a flawed or lacking public education system. Past and future research into the inadequacies and inequity that exists in the public education system need to act as a catalyst to policy changes, and intervention implementations to solve the issues that continue to persist. This study focuses on the factors that influence the academic performance of learners in matric in King Williams Town. The importance of this research is to investigate the issues that negatively impact on the performance of Grade 12 learners at Breidbach High School. Further, the importance of this study is to share the findings of the research with community members as well as the Department of Basic Education with the view and hope that they will address these issues. The research question is: What are the factors influencing academic performance of Grade 12 learners at Breidbach High School in Breidbach outside King Williams Town? The research objectives are as follows: to investigate and highlight factors associated with poor academic performance in the participating high school at Breidbach in King Williams Town, to contribute within the anthropology of education, adding to an already existing body of knowledge, with specific reference to the participating high school in King William’s Town and to come up with the recommendations with the view of addressing some of the challenges faced by the participating high school in King Williams Town. The study followed a qualitative approach which included various techniques and ethical compliance was adhered to. For the proposed study, the researcher will use ‘academic performance’ as a guideline for the conceptual framework. , Thesis (MA) -- Faculty of Humanities, Department of Sociology and Anthropology, 2021

- Description: New technological developments in the field of Hybrid Electric Vehicles (HEV’s), vehicle stop-start applications and electrical power utility devices have brought about new demands on the use of energy storage devices such as the Pb-acid battery. These applications require a new understanding and research into the material chemistry of the battery where it has to functionin a Partial State of Capacity Cycling (PSoCC) or High Rate Partial State of Capacity Cycling (HRPSoCC)duty. The Pb-acid battery is well known for its use in the automotive industry where it had worked for decades as a typical Starter, Lighting and Ignition (SLI) power source. However, the conventional Pb-acid battery is not suitable for the new types of vehicle demands and applications. When the Pb-lead acid battery is subjected to PSoCC conditions, very quickly excessive amount of non-conducting PbSO4crystals are formed on the negative plates of the battery that then drastically reduce its useful life in application. Over the years, researchers have shown that the small addition of certain carbon types to the negative plate active material (NAM) during battery manufacturing can reduce the sulfation effect thereby increasing its use the modern vehicle applications. This study investigated industrial manufactured cells that contained up to 0.5 % by weight two types of carbons in the NAM. These were compared to standard built cells in terms of their standard achievable capacities at various rates, their Cold Cranking Ability (CCA), their Dynamic Charge Acceptance (DCA) and a simplified PSoCC test. The carbons were classified as an activated carbon and a carbon nano-fiber and were included as a dry weight additive during the standard paste manufacturing process of the negative plate. Cells were built with a 9-plate configuration using standard expanded grid positive plates with a nominal rated capacity of 36 Ah. The cells were formed and subjected to a number of electrochemical tests, of which selected negative plates were then studied using Scanning Electron Microscopy (SEM) and Electrochemical in-situ Atomic Force Microscopy (EC-AFM). The microscopic study was then used to try and relate the observed material characteristics of the NAM with the carbons to the electrochemical results observed when testing a built cell. , Thesis (MA) --Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: The purpose of this study was to establish the extent to which the provision of social housing can be enhanced through public-private partnerships (PPPs) in the Buffalo City Municipality. A total quality management approach was used as a foundation to understand the application of PPPs in social housing delivery in the Buffalo City Municipality. The study was desktop research to understand the role of PPPs in the provision of social housing. The findings of the study revealed that PPPs provide additional capital for social housing development. The study highlighted that PPPs play a crucial role in providing alternative management and implementation skills as well as offering greater efficiency in the utilisation of financial resources in the delivery of social housing. The findings of the study further revealed that PPPs accelerate social housing delivery through the provision of additional sources of finance where the government is unable to increase public debt to meet investment needs. The study also identified a plethora of constraints that can hinder the adoption of PPP initiatives in social housing delivery. These include capacity constraints, financial constraints, lack of access to land and an unfavourable policy environment. Subsequently, the study advanced a set of recommendations in this regard that includes the creation of transparent and competitive procurement processes, government support in terms of financial incentives, review of the regulatory framework to improve access to land and the regulation of financial services institutions for access to affordable housing credit. , Thesis (MA) -- Faculty of Humanities, Department of Public Management and Leadership , 2021

- Description: The separation of [IrCl6]2- from [RhCl5(H2O)]2- by silica microparticles functionalized with 1,10-diamindecane (C10) and quaternized with 4-nitrobenzylchloride (NO2Benz) in various hydrochloric acid mediums was investigated by continuous column studies. The sorbent materials were synthesized using three different routes: Synthesis route 1 (NaI catalyzed synthesis of diammonium functionalized silica microparticles), Synthesis Route 2 (via silylazation of silica followed by functionalization) and Synthesis Route 3 (silane-based sorbent material). The functionalized sorbent materials were characterized by NMR, Microanalysis, SEM-EDS, FT-IR, TGA and BET surface area. The separation efficiency of the quaternary diammonium cations was investigated under dynamic flow adsorption conditions. Preliminary ICP-OES runs were done, at 6 M HCl, to assess which synthesis route gave the best performing sorbent material. [IrCl6]2- selectivity of the sorbent materials was achieved by washing with an HCl solution to remove unadsorbed metal species, then stripping off the [RhCl5(H2O)]2- with 0.05 M of sodium chlorate and the iridium species was eluted with a 20% HCl solution. From the preliminary ICP-OES, loading capacities were calculated, and it was observed that the three sorbent materials from synthesis route 2 (13.89 mg/g for (4) SSC10NO2Benz-A, 1.44 mg/g for (5) SSC10NO2Benz-HoA, and 1.0859 mg/g for (6) SSC10NO2Benz-DoA) showed the highest uptake of [IrCl6]2- and route 1 (1.89 mg/g for (1) SSC10NO2Benz-A, 1.25 mg/g for (2) SSC10NO2Benz-HoA and 0.99 mg/g for (3) SSC10NO2Benz-DoA ) and Route 3 (0.55 mg/g for (7) SC10-AI and 0.755 mg/g for (8) SC10-ACl) materials did not perform efficiently enough, thus were not used further for the HCl study. Within synthesis route 2, three sorbent materials were evaluated, which had varying quantities of the cation: SSC10NO2Benz-A (having a quantity previously used in our research and denoted A), SSC10NO2Benz-HoA (having a quantity Half of A) and SSC10NO2Benz-DoA (having a quantity double of A). SSC10NO2Benz-A showed the highest loading capacity than SSC10NO2Benz-HoA and SSC10NO2Benz-DoA; HCl studies were carried out using SSC10NO2Benz-A. HCl solution having different concentrations (5, 5.5 , 6 , 6.6 and 6.8 M) were used to prepare the metal solutions. This was done to assess which HCl concentration gave the best metal solution containing high amounts of [IrCl6]2- and [RhCl5(H2O)]2-, which would result in a more efficient separation. An auto titrator was used to standardize the HCl concentrations, and the metal ion chloride species solutions were determined by UV-Vis, and their concentrations were confirmed with ICP-OES. Column sorption of iridium and rhodium on SSC10NO2Benz-A using these HCl solutions was carried out, and loading capacities of [IrCl6]2- were obtained. The loading capacities of the 5 M, 5.5 M, 6 M, 6,6 M and 6.8 M HCl solutions for [IrCl6]2- were 2.64, 4.01, 13.89, 18.15 and 7.23 mg/g, respectively. The optimum separation conditions were thus determined by investigating effective parameters such as the method of synthesis, silica to cation ratio, HCl concentration and flow rate. This thesis presents quaternary diammonium sorbent materials that could be applied in feed solutions from ore processing for iridium recovery. , Thesis (MSc) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2021

- Description: In this work, the rheological properties of alumina slurries milled to different particle sizes were investigated. Viscosity increases as the particle size decreases. When increasing amounts of calcium hydroxide, strontium hydroxide or barium hydroxide are added, the viscosity first goes down and then goes up. This can be explained in terms of changes in pH and changes in ionic strength impacting on the surface potential of the particles in suspension. Adding the same concentration of different cations results in different viscosities, with the order being (from high to low viscosity) Ba>Sr>Ca. Effects of partial dissolution of and structural changes to the alumina particles at high pH cannot be excluded. In order to better understanding the different effects, it was attempted to measure the zeta potential of the slurries at different pH values. This resulted in highly positive zeta potential values over the complete pH range, without the observationof an iso-electric point. This does not fit to the observed changes in rheology and contrasts withliterature data. One explanation would be that the measurement system used is unsuitable to yield correct zeta potential values for the materials under investigation. , Thesis (MSc) -- Faculty of Science, Department of Chemistry, 2021

- Description: This research was directed towards the current state of the relationship between the Performance Management Development System and compensation in the City of Cape Town Municipality. The research approach adopted in this study was a qualitative method. Desktop analysis and case study design were used as secondary data collection tools. Since the democratization of South Africa in 1994, the focus has been directed towards the maximising of economic growth and development. The road to development has been challenging since the inception of democracy. Organisations are operating in a dynamic and highly competitive environment which requires adjustments and development of strategies to remain relevant. Compensation is one of the ways different organisations have adopted as a strategy for attracting and retaining suitable employees as well as maintaining performance management. The essence of a well-functioning performance management development system has played a critical role in providing an effective system in the public service. The main objective of compensation is to ensure an organisation has the right resources necessary to motivate employees’ performance needed to achieve the organisational strategy. The study found that a compensation strategy leads to increased employees’ performance. The findings indicated that there is a positive connection between the compensation strategy and the performance of the employees. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2021
