  • Description: Thermoluminescence of synthetic quartz annealed at 1000 ºC for 10 minutes has been studied. The aim was to study mechanisms of thermoluminescence in annealed synthetic quartz and to discuss the results in terms of the physics of point defects. The sample was irradiated with a beta dose of 10 Gy of beta radiation and then heated at a linear heating rate of 1 ºC.s-1 up to 500 ºC. The thermoluminescence (TL) glow curve consists of three glow peaks. Peak I at 74 0C (main peak) with high intensity as compared to the other two peaks. Peak II at 144 ºC is more intense than peak III at 180 ºC. This study was on the main peak (MP) at 74 ºC and peak III at 180 ºC. Kinetic analysis was carried out to determine the trap depth E, frequency factor s and the order of kinetics b of both peaks using the initial rise, peak shape, variable heating rate, glow curve deconvolution and isothermal TL methods. The values of kinetic parameters obtained were around 0.7 to 1.0 eV for trap depth and in the interval of 108 to 1015 s-¹ for frequency factor for both peaks. The effect of heating rate from 0.5 to 5 ºC.s-¹ on the TL peak intensity and peak temperature was observed. Also the effect of thermal quenching was observed at high heating rates. Since the TL glow curve has overlapping TL peaks, the Tm-Tstop method from 54 ºC up to 64 ºC and E -Tstop methods were introduced where a first order single peak was observed. Phototransfered thermoluminescence (PTTL) was investigated and characterized by three peaks. First PTTL peak I at 72 ºC, peak II at 134 ºC and peak III at 176 ºC. Analysis was carried out on peaks I and III for the effect of dose dependence from 20-200 Gy. Thermal fading was observed on PTTL peaks I and III, after storage time of 30 minutes.

  • Description: This study is aimed at extracting cellulose and nanocelluloses (cellulose nanocrystals (CNCs) and cellulose nanofibres (CNFs)) from maize stalks and flax fibres. Both flax fibres and maize stalks are composed of cellulose, lignin, hemicellulose and extractives. The extraction of cellulose involves the removal of lignin, hemicellulose and extractives. The presence of these components in plant fibres hinders the extraction of cellulose and nanocelluloses. Prior to extraction of cellulose, the different concentrations (1 wt.%, 1.5 wt.% and 2 wt.%) of NaOH were optimised. However, chemical compositions and XRD results revealed that the treatment of flax fibres with 1.5 wt.% sodium hydroxide (NaOH) gives optimum results and this concentration was further selected for the extraction of cellulose. Cellulose was extracted by chemical treatments (sodium hydroxide (NaOH), sodium chlorite (NaClO2) and potassium hydroxide (KOH)) and a combination of chemical treatments and mechanical process (supermass colloider). The materials obtained after each treatment stage during the extraction process were characterised by different characterisation techniques such as Fourier transform infrared (FTIR) spectroscopy, environmental scanning electron microscopy (ESEM), X-ray diffraction (XRD) and thermogravimetric analysis (TGA). The results from the aforementioned characterisation techniques confirmed that cellulose was successfully extracted from flax fibres and maize stalks. Cellulose nanocrystals (CNCs) were extracted by sulphuric acid hydrolysis accompanied with ultra-sonication from cellulose obtained from flax fibres and maize stalks. The extracted CNCs were rod-like material with diameters and lengths in nanoscale and microscale, respectively. On the other hand, cellulose nanofibres (CNFs) were extracted by mechanical process (supermass colloider). The extracted CNFs were web-like material with diameters and lengths in nanoscale and microscale, respectively. The dimensions of nanocelluloses were measured by atomic force microscopy (AFM). Their dispersion was investigated by light polarised microscopy. The extracted nanocelluloses and cellulose were used to produce nanopapers and micropaper. Nanopapers mimic the traditional paper, the only difference of the nanopapers is that they are produced from high aspect ratio nanomaterials. Both nanopapers and micropapers were prepared by solvent evaporating method. Their thermal, optical and mechanical properties were investigated and compared. The mechanical and thermal properties of nanopapers produced from CNFs were better than those produced from CNCs and micropapers. On the other hand, nanopapers produced from CNCs were more transparent in comparison to nanopapers produced from CNFs and micropapers. Cellulosic fibres have attracted a considerable attention in composite materials due to their high tensile strength and tensile modulus. This study is focused on the development of biocomposites of polyfurfuryl alcohol (PFA) by in-situ polymerisation in the presence of acid catalyst (p-toluene sulphonic acid). Biocomposites were produced by reinforcing PFA with flax fibres (untreated and treated), nanoparticles and CNCs. The biocomposites reinforced with CNCs and flax fibres showed an improvement in mechanical, thermal and thermo-mechanical properties. On the other hand, biocomposites reinforced with nanoparticles obtained from treated maize stalks showed an improvement in mechanical and thermal properties while biocomposites reinforced with nanoparticles obtained from untreated maize stalks showed lower mechanical properties and decreased thermal stability.

  • Description: This report is the result of a literature study and questionnaire which gave insight on the role of officials in the rehabilitation process. Correctional Services has adopted a new approach, where offenders need to change their negative behaviour and be rehabilitated. Corrections have a societal responsibility towards the community to guide the offender on his rehabilitation path. This study was conducted to give a better understanding of rehabilitation to offenders The purpose of this research is to determine if the Department of Correctional Services delivers on its legal and social responsibility towards the rehabilitation of offenders. In this study the researcher gathered information on the department policies, training of officials, the programmes currently available in Correctional Services, and also the involvement of the community in this process. Corrections cannot work alone, and needs the help of the community and leaders in the community to assist it in this process. Correctional Services faces many challenges in order to succeed in the rehabilitation of offenders. Currently there is a shortage of officials in the Department of Correctional Services, and the Department cannot, therefore, fully succeed in its rehabilitative role. Another aspect is that rehabilitation programmes are voluntary, and offenders can decide if they want to become involved or not.

  • Description: With the rising day to day expenses especially post retirement when income streams are running low, financial planning helps to better manage such events more effectively. Through a proper financial plan individuals do not just deal with wealth creation and wealth protection but are able to start from the basics of budgeting, were individuals are taught how to live within their means. In South Africa, financial planning has been seen to be focusing on the more affluent clients. This has resulted in a distinct lack of academic literature done on middle income black professionals in relation to financial planning. This is despite the increase of the black middle class population which has been accompanied with an increased purchasing power exceeding that of the previously wealthier white middle class. The growth of the black middle class in South Africa has been accompanied with stumbling blocks, ranging from the lack of financial literacy of the black middle class, negative attitude towards the financial services industry that influence financial decision making, and the pre-existing perception that are built on the lack of financial awareness, a legacy left by the history of division that South Africa had. Therefore the main aim of this study was to investigate the factors that influence middle income black professionals’ intention to seek financial planning assistance. Both secondary and primary data were used to help achieve the primary research objective of the study. An in-depth literature review on the financial planning industry in South Africa that included the nature of financial planning, the role of the financial planner, the six step financial planning process, the importance and benefits of financial planning, current trends in the financial planning industry, financial planning and the middle income black professionals and the factors that influence the middle income black professionals’ intention to seek financial planning assistance was conducted. Selected study of the literature revealed six factors that might influence an individual’s intention to seek financial planning assistance, namely Attitude, Awareness, Family financial norms, Financial self-efficacy, Trust and Perceived rewards. A theoretical framework was proposed illustrating the relationships between the factors influencing middle income black professionals’ intention to seek financial planning assistance that were to be empirically tested. A positivistic research paradigm was followed and a quantitative approach was implemented. Snowball and convenience sampling was used and a total of 300 questionnaires were distributed to middle income black professionals in the Eastern Cape. For the purpose of this study, middle income black professionals refer to qualified working individuals in the middle income bracket, including teachers, nurses, administrative workers, office-based municipal workers and employees in the private sector, such as those working in the banks and retail supervisors. These were distributed to verify their intentional behaviour with regards to seeking financial planning assistance. From the 300 questionnaires distributed, 271 usable questionnaires were yielded. Statistical techniques including descriptive statistics, Pearson’s product moment correlations and multiple regression analysis were performed on the gathered data. Demographic data relating to the gender, age and first language of the respondents was collected. An exploratory factor analysis was undertaken, and Cronbach’s alpha coefficients were calculated to assess the validity and reliability of the measuring instrument. As a result of the factor analysis the operational definitions were rephrased. The Cronbach’s alpha coefficients reported were all greater than 0.7, deeming the scales measuring the various dimensions reliable. Descriptive statistics were calculated to summarise the sample data, and Pearson’s product-moment correlation coefficients were established to investigate the associations between the variables. Significant positive correlations were reported between all of the variables. The results of the descriptive statistics showed that the majority of respondents agreed that Attitude (77.73%), Financial self-efficacy (61.13%) and Perceived rewards (76.98%) were the most influencing factors. The results of the multiple regression analysis revealed that three factors had a significant positive influence on the dependent variable Intention to seek financial planning assistance, namely Attitude, Awareness and Perceived rewards. The factors Family financial norms, Financial self-efficacy and Trust were rejected as there was no significant relationship found between them and the Intention to seek financial planning assistance. Based on the results, it is recommended that financial service providers focus on financial education by engaging with the middle income black professionals through accessible media such as radio and television. Furthermore, financial service providers should shift from a sales orientated philosophy to a lifestyle financial planning advice philosophy that encourage value for the service rendered to the client and sells benefit than product. The Department of Education should put in place basic financial planning curriculum that can be deliverable at schooling level and is examinable in order to improve the basic financial knowledge and awareness amongst the next generation. Lastly the middle income black professionals are encouraged to read their documents when taking out financial products as well as financial related articles to develop their financial knowledge.

  • Description: This treatise revisits the process of the implementation of the Coega Project and discusses political economic issues which emerge therein locating them in the political economic context of post-1994 South Africa. Based on an in-depth study of the “Coega Story”, and three years of observing the Coega Development Corporation engaging in the political economic space to implement the project, key themes which are relevant in understanding the nature of politics in the country are highlighted and discussed with a view to drawing lessons for future implementers of economic development projects and policy makers. Key discussions in the study include a critical analysis of the symbiotic relationship between politics and development (or broadly the economy) – where emphasis is made about the centrality of politics in implementing economic development projects; the developmental state – where key characteristics of a developmental state are highlighted; the transition from apartheid to democracy and its implications on the nature of political relations post-apartheid; industrial development as a growth strategy and the interplay of social forces in the post- 1994 political economic space. The Coega Project is located within the broader context of the ruling party seeking to advance what is called the second and, perhaps the ultimate task of the liberation struggle, socio-economic liberation. Its strategic fit in that task is discussed critically taking into account paths to industrialisation as they have been observed from Newly Industrialising Countries and South Africa’s attempts at industrialisation before and after 1994.

  • Description: In democracies and purportedly free market economies, questions of “who gets what, when, and how” ought to be resolved mainly through free competition, where those with the competitive advantage on merit are guaranteed to succeed. If it is political parties, they only have to compete well and fairly to win elections. If it is businesses, they ought to have the best value and price and they win customers. However, there are institutions which regulate this competition and political economic behaviour. Interest groups such as business chambers, industry and professional associations, as well as various structures of representation engage in the political economic space to sway the distribution outcomes from these “institutions” in the favour of their members. To do so, at times they use methods that affirm the principles and spirit of free competition and at other times, they do not. This thesis reviews the political economy of transformation within the construction sector in Nelson Mandela Bay to further advance knowledge within the subfield of political economy in South Africa. By looking at a specific economic sector, the study adds an important element to the sub-discipline, a nuance to the debates about the role of the state in the economy or macroeconomic policy and the much studied mining-energy complex. The study focuses on the role of small business forums created mostly by newcomers within the construction sector in the city and the methods they used to increase the share of their members in construction sector revenues. Their methods were unconventional and earned them the unfavourable term of ‘the construction mafia’. Through a grounded theoretical research process, this study details the story of the rise and fall of forums and dissects it in line with ongoing debates within political economy and related disciplines, particularly about the nexus between politics and business as well as the role of interest groups in pluralist political systems. Among other things, the study finds that the forums did not see the construction industry as a free market and did not take principles of competition in the sector as a given. As such, they sought to make and remake institutions of the sector in ways that could increase their share of revenues. In similar fashion to the roles of iinjoli nosokhaya in traditional isiXhosa ceremonies, they accorded to themselves the right to distribute benefits to their members contrary to legal and general market prescripts. , Thesis (PhD) -- Faculty of Humanities, School of Government and Social sciences, 2022

  • Description: This study examined whether or not financial intermediation can explain the variations in the savings-investment ratio in South Africa during the period 1990 to 2012. The study specifically tests the McKinnon Conduit Effect hypothesis which states that increasing interest rate raises the capacity of financial savings via financial intermediaries based on data from South Africa. Apart from informal graphical test, this study employed formal tests such as the Augmented Dickey-Fuller and Phillips Perron stationarity tests to test the properties of the variables considered, including interest rates, for stationarity. In order to ascertain the long-run and short-run dynamics between its variables, the Johansen co-integration test is utilized, while the Error Correction Mechanism is also employed. Results from the study state that financial assets (a proxy for financial intermediation), income and real interest rate all positively impact the savings-investment ratio. Additionally, short-run analysis results showed that income, financial assets and real interest rates positively influence the savings-investment ratio. Real interest rates were seen as being both positive and statistically significant. Therefore the study recommended that the financial services sector and the South African Reserve Bank (SARB) should work together as this will result in the improvement of efficiencies in price discovery with regards to bank charges, access to banking facilities and the timely provision of services in order to encourage savings (for investment purposes) in the South African economy.

  • Description: Alzheimer’s disease (AD) is the most devastating neurodegenerative disorder that effects the aging population worldwide. In this study three hypotheses of AD are explored, the β-amyloid cascade hypothesis, the β-amyloid metal binding hypothesis and the oxidative stress hypothesis are explored. In the first case compounds from the South African Natural Compounds Database (SANCDB) are docked to models of β-amyloid fibrils and the properties of these fibrils under pulling simulations are compared to a known small molecule disruptor of β-amyloid, wgx-50. In these simulations SANCDB compounds are identified that disrupt β-amyloid in a similar manner to wgx-50. In these simulations the disruption to the free energy of binding of chains to the fibrils is quantified. For metal binding and oxidative stress hypotheses, problems in simulation arise due to only fragments of β-amyloid being present in the Research Collaboratory for Structural Bioinformatics protein data bank (RCSB PDB), as determined from NMR experiments. In this work, β-amyloid is set up under periodic boundary conditions to simulate a fibril under reasonable computational time. Within these periodic boundary conditions, β-amyloid has been solvated in copper and zinc rich environments and diffusion of these metals around the fibrils has been explored. The localization of these metals (in simulation only using van der Waal’s and electrostatic terms) around the fibril has led us to explore other possible metal binding sites. Metal bound to the infinite fibril has been optimized at the QM/MM level and some of the reactive oxygen species in the presence of the fibril are quantified.

  • Description: Climate variability affects rural households and agricultural productivity, yet it is just one of many stresses that vulnerable rural households have to cope with. Climate variability is not as noticeable as weather variability, because it happens over seasons and years. It is the manner in which climate fluctuates above or below a long-term average value. Without measures at local and national level to adapt to climate variability, risk of food insecurity will continue to increase at household level. The objective of the study was to determine factors affecting adaptation to climate variability. Purposive sampling was used to identify households who participated because of un-availability of sampling frame. Information was elicited from the selected households with the aid of a semi-structured questionnaire. The study utilised a cross-sectional survey of 205 farming households in Tyhume Valley communities. Data gathered was subjected to descriptive statistics, Cross tabulations and Binary logit model. The results indicate that rural households from Tyhume Valley communities practiced coping adaptation through use of the following adaptation strategies; crop rotation, planted drought resistant crops, changed planting dates and used indigenous strategies such as using ash to kill mule (intuku). Most of the households used irrigation as the coping strategy to adapt to climate variability. However, heatwave, high winds, employment status, cell phones, age and gender of the rural households’ heads have effects on households’ adaptation to climate variability in Tyhume Valley. In view of the research findings, a large number of farming households are old and are females, there is a need for development of labour saving technologies and extension services to increase the likelihood of adaptation of climate variability by vulnerable farmers such as women and elderly farmers.The study also recommends that there must be a development of infrastructure for farmers as they are negatively affect by high winds due to low infrastructural development.The study also shows that farming households who have access to cellphones are more likely to adapt to climate variability, therefore the study recommends that communication of farming households must be improved.Adapting to climate variability is an increasingly important issue in agriculture and one that is likely to persist for many years.

  • Description: The sustainable use of the environment for agriculture has become a global priority, requiring urgent solutions in view of intensifying competition. The South African government and the agricultural sector drafted a strategic plan for South African Agriculture. In this plan it was argued that the potential for the horizontal expansion of agricultural production is limited with one of the limitations being that unused high and medium potential land is scarce. This implies that the challenge for higher agricultural production is immense because primarily it would have to come from increased efficiency. All businesses are confronted by change at some time in their history in which agribusiness in South Africa has been subjected to changes in its past. In this era of hyper competition, agribusinesses are faced with constant change. It is how businesses deal with that change that will determine how successful they will remain in the future. The main problem of this research was to determine if farmers in the Great-Kei Region have the appropriate strategies in place to manage environmental constraints effectively. Therefore, the identification and isolation of prominent environmental constraints, through literature review and survey data gathered and analysed, would assist agribusinesses in the planning and prioritising of investments. The investment would be aimed at facilitating the development and sustainable growth in the Great-Kei Region. In this study, a quantitative, descriptive and non-experimental research design was followed. The target population of the study was farmers with farming businesses operating in the Great-Kei Region. There was data obtained from the Eastern Cape Department of Agriculture provincial office in Komga servicing the Great-Kei Region. The data obtained were lists of registered commercial farmers from the Komga iv Agricultural Association and emerging farmers operation in the region. The data obtained did not include all the farmers operating in the Great-Kei Region. The combined sum of farmers from both lists was 38 farmers (N = 38). The population N = 38 was used as a sampling frame representing the population of farmers in the Great-Kei Region. The population of this study consisted of owners or farm managers running the farming businesses and excludes other farm employees employed at the farms. Farmers with agribusinesses in the area who produced either livestock farming or crop farming or both were included for the study. The results of the survey revealed key findings, which enabled the researcher to draw meaningful conclusions and recommendations. The recommendations suggested how farmers can overcome the identified macro, micro and internal environmental constraints affecting them in the Great-Kei Region. Further identification of strategies currently employed by farmers in managing environmental constraints and the competency levels, indicated where gaps resided with strategies currently employed by farmers and where possible change would be required.

  • Description: Despite existing literature that indicates that Information and communication technologies (ICTs) act as tools for social change and development, there is still limited empirical evidence that demonstrates this. An outcome and impact assessment based on a comprehensive (holistic) evaluation is deemed appropriate at a time when many ICT4D programmes fail to effectively demonstrate their impact towards rural development. A comprehensive evaluation is one that incorporates the evaluation of the need, design, implementation, outcome and impact, efficiency, and scalability of a programme. These stages make up the different domains of an evaluation lifecycle. The following study aims to develop an outcome and impact assessment framework for ICT4D programmes. It forms part of continuous research associated with the development of a rural ICT Comprehensive Evaluation framework. A theoretical approach, using Design Science and Weick’s theorizing process, was applied to investigate the development of a framework (design artefact) for outcome and impact assessment of ICT4D programmes. The theorizing process analysed existing outcome and impact assessment frameworks from social programmes, information systems/technology programmes, and ICT4D programmes. The output of the theorizing process proposes five critical themes of outcome and impact assessment of rural ICT4D programmes that should be assessed. These themes include: Strategic Value, Most Significant Change, Empowerment, Livelihoods, and Sustainability. To assess its utility, the framework was implemented in the Siyakhula Living Lab and Information and Communication Technology for Rural Education (ICT4RED) projects in South Africa. Through the application of the framework in real life ICT4D contexts, the lessons learned contributed to its revision and enhancement. The proposed framework aims to guide evaluators through the assessment of outcomes and impacts in ICT4D programmes. It provides a foundation and justification for the selected outcome and impact assessment themes that contribute to a comprehensive evaluation. An outcome and impact assessment that is informed by: baseline; needs assessment; programme theory assessment; and process assessment data, provides ICT4D evaluators and project stakeholders with meaningful outcome and impact feedback. Having such an approach to outcome and impact assessment ensures that the evaluation process is seen more holistically as part of the ICT4D project as a whole. , Thesis (PhD) -- Faculty of Commerce, Information Systems, 2017
