Brand image legacy of the 2010 FIFA World Cupтм : a long-term assessment
No full textThesis (MTech (Tourism and Hospitality Management))--Cape Peninsula University of Technology, 2018.Sport mega-events are a powerful tool for branding nations. There has been a significant shift in countries that bid for and win the rights to host sport mega-events. Historically, Western countries used to be leaders in winning rights to host such events; however a new emerging trend has seen developing countries winning the rights ahead of developed ones, for example, South Africa, Brazil and Russia winning the rights to host the FIFA World CupTM. South Africa faced a serious branding challenge leading up to the 2010 FIFA World CupTM. Therefore, one of the primary objectives of hosting this tournament was to change international tourists’ perceptions of South Africa. There has been limited research on the brand legacies of the 2010 FIFA World CupTM, hence this research examined the brand image legacies of the tournament in the long run. It is believed that the football fans who attended the 2016 UEFA European Championship either visited South Africa during the 2010 FIFA World CupTM or watched the tournament on television (TV) at home, therefore they have certain perceptions of South Africa as a sport tourism destination. A quantitative methodology was employed to survey football tourists at fan parks and stadium precincts in five metropolitan cities in France during the 2016 UEFA European Championship, using a spatially based systematic sampling technique. In total 391 football tourist questionnaires were completed. The key findings reveal that prior to the 2010 FIFA World CupTM, football tourists’ perceptions of South Africa as a sport tourism destination were generally positive; however they indicated that they were very concerned about safety and security, as well as segregation issues, prior to the tournament. It can be argued that the tournament had a significant impact on reinforcing the positive perceptions of the destination as well as reducing the negative perceptions of the destination. The findings reveal statistically significant differences in most aspects between tourists’ perceptions prior to, and six years after, the 2010 FIFA World CupTM. Tourists’ perceptions on most aspects changed positively six years after the event, including those that were major concerns prior to the tournament. The findings also show that there has been very little repeat visitation to South Africa since South Africa hosted the 2010 FIFA Word CupTM. However, an overwhelming majority of respondents indicated that they were willing to travel to South Africa should it host another sport mega-event in the near future. The key findings of this study have a wider applicability to sport mega-events legacy research and body of knowledge. These key findings can assist destination marketers in managing the destination image and foster a greater understanding of brand image legacies of past mega-events in order to inform the bidding and hosting of future sport mega-events
Reengineering the residence application and admission business processes at a selected tertiary institution
No full textThesis (MTech (Business Information Technology))--Cape Peninsula University of Technology, 2018.Institutions of higher learning are operating in an environment that is continuously informed by the markets and government regulations, hence the need for continuous improvement initiatives in order to remain relevant to the dynamic changes in higher education. The improvements are done by reviewing the course content, operations, and business processes, which includes an application and admission process. This study analyses the residence application and admission process (RAAP). The business processes and Enterprise Resource Planning (ERP) system support the realisation of the application and admission process of the university. The review of the current application and admission process will be based on business processes, business process reengineering, and the business process modelling theory. Therefore, the problem statement for the study is that the impact of information flow during the application and admission of students for residency at the university involves business processes that are inefficient and ineffective. This results in mistakes being made by administrators, and students who are dissatisfied. The study is based on two research questions: Firstly, what strategies can be used to improve the application and admission process of the role players at the selected tertiary institution, and secondly, how does the application and admission process affect service delivery to the students and residence administrators at the selected tertiary institution? The aim of the study is to explore how the participating students and administrators in the residence application and admission process perceive the efficiency of university business processes. A further aim is to explore how the processes can be reengineered to fulfil the requirements of the students and administrators. The research methodology employed to resolve the problem logically is qualitative in nature. A research paradigm guides the actions of the researcher with regard to the generation and interpretation data, which results in knowledge production. The inductive research approach is well suited for the research strategy. For the purpose of this study, a case study strategy is deemed suitable because of its qualitative nature, and comprehensive knowledge of the university processes is required to understand and address the research problem. The unit of analysis of the study is the university’s administrative department business processes. The purposive, non-randomly selected students who applied for residency and the employees of the applicable departments within the university form the unit of observation, which is also a source of data. The data are collected by means of interviews using semi-structured questionnaires, with the samples being non-random and purposively selected. The data collected in the case study are then be summarised and categorised into themes. The themes are uses to present the “As-Is” and the “To-Be” application and admission process
An analysis of the environmental impacts of biomass application in hybrid microgrids in South Africa
No full textThesis (Master of Engineering in Electrical Engineering)--Cape Peninsula University of Technology, 2018.In Sub-Saharan Africa (SSA), there are several challenges that hinder development. One of these challenges is access to electricity. There are numerous benefits to having access to reliable electricity. These include less time spent fetching water from rivers and dams, as water purification systems for households could be used in villages; children in villages would be able to spend more time doing their schoolwork and not fetching wood for fire; and automated irrigation systems could be used for villagers to farm and make an income. Finding alternative ways to generate electricity would enable access to electricity for regions that currently do not have the electricity. This means that large organisations need to find alternative ways of generating electricity, as they have the means to do so. With the current renewable energy technologies available, there are now more ways in which electricity could be generated. The use of biomass is no exception to this. With constant developments in the renewable energy sector, waste-to-energy (WtE) is proving to be a viable method to generate electricity. The main aim of this research was to determine if a commercial food retailing organisation could use their food waste for generating electricity for their own use to reduce their demand from the central grid. A way of determining the viability of this type of technology is using a software that simulates renewable energy projects. In this research, an organisation was contacted for waste data. Systems for two of the stores will be simulated and results will be discussed. The organisation will remain anonymous. The software used in this research is System Advisor Model (SAM), which was developed by the National Renewable Energy Laboratory (NREL) in the United States. In the results, three results were discussed. These are the monthly energy, monthly heat rate and the monthly boiler efficiency for each of the stores for Store 1, the annual energy simulated was 138,509 kWh and 131,677 kWh for Store 2. Monthly energy averages for each store were 11,542 kWh for Store 1 and 10,973 kWh for Store 2, respectively. There are several opportunities for research based on the findings. These include researching other food sectors in the study; conducting a financial analysis of small-scale WtE systems; constructing a prototype of the system; and using three different softwares to simulate a system for the same project
In-vitro propagation studies of the endangered succulents Drosanthemum Micans and Drosanthemum Hallii (Aizoaceae)
No full textThesis (MTech (Horticulture))--Cape Peninsula University of Technology, 2018.Drosanthemum micans and Drosanthemum hallii are endangered succulent shrubs of horticultural and medicinal value. They are restricted to the Succulent Karroo, which is one of the world’s biodiversity hotspots. The species risk extinction from illegal over-harvesting for water-wise gardens, erosion by occasional flush floods from ephemeral rivers, competition from alien invasive species, overgrazing and clearing of land for agriculture and human settlement. Although seeds and cuttings may be used in propagating these species, they often require seasonal collection and planting and cuttings struggle to establish, hence the need for in-vitro propagation as an alternative solution. Thus, the main objective of the study was to develop a method for rapid in-vitro shoot and root multiplication and acclimatization of D. micans and D. hallii. To initiate shoot formation, disinfected leaf and stem nodal explants were cultured in Murashige and Skoog (1962) media supplemented with different rates (0, 10, 20 or 30μM) of 2-isopentyladenine, 6-Benzyladenine and kinetin for D. hallii or 2-isopentyladenine, 6-Benzyladenine and Thiadiazuron for D. micans. Shoots from explants were rooted in varying rates (0, 10, 20 or 30μM) of IAA for root initiation. Three media, which were used in previous studies, were tested for acclimatization of rooted explants in i) vermiculite, ii) sand (50%): vermiculite (50%) or iii) sand (75%): perlite (25%). For quantitative evaluation of plant stress, chlorophyll fluorescence index (Fv/Fm) was measured as a proxy for plant stressf stress. It emerged that stem nodal explants of D. hallii tend to produce multiple shoots whilst leaf explants tended to produce callus when cultured in full-strength Murashige and Skoog (1962). Shoot multiplication was optimal in both D. hallii and D. micans at 10 μM of kinetin. Root formation in both D. hallii and D. micans only occurred when shoots were transferred to a full-strength Murashige and Skoog (1962) media without any phytohormones added. The intensity of tissue browning increased at higher levels of cytokinins, suggesting an interaction of plant growth regulators with exudates from explants. Different acclimatization media tested showed no significant differences in the level of stress (Fv/Fm). It is recommended that Murashige and Skoog (1962) media with10 μM kinetin be used for shoot development and multiplication, followed by transfer of the shoots to fresh full-strength Murashige and Skoog (1962) media without hormones for root development. Acclimatization of the rooted explants was possible in one of the following media: i) vermiculite, ii) sand (50%): vermiculite (50%) or iii) sand (75%): perlite (25%) and in a misted greenhouse (ca. 60% RH), with gradual weekly reductions in humidity by 10% over 2 weeks
Multiple stakeholders’ perceptions of the impacts of a carnival in Cape Town
No full textThesis (MTech (Tourism and Hospitality Management))--Cape Peninsula University of Technology, 2018.Carnival events have become significant factors in tourism development and marketing initiatives of most destinations. The developments, in threefold, economic, socio-cultural and environmental experienced by host communities of tourism attractions and resorts result in the emergence of carnival events as critical destination products. The current research found that the selected stakeholders, particularly residents, businesses and event attendees’ perceptions are often overlooked although they are directly impacted by carnival events, especially when they reside (for residents and businesses) in close proximity to the event location. In addition, tourism businesses operating in the Green Point area, the place where the carnival parade takes place, were included in this study to ascertain their views about the Cape Town Carnival. In most cases, successful carnival events are underpinned by community support as well as the visitors or attendees to the event; therefore, it is crucial to examine stakeholders’ perceptions towards such events.
The aim of this study was to determine how selected stakeholders (residents, businesses, and event attendees) perceive an annual cultural event, the Cape Town Carnival, hosted in a Cape Town suburb. It also sought to establish the overall value of this event following a triple bottom-line approach (economic, socio-cultural, and environmental). This investigation explored the perceptions and experiences of the residents, businesses, and event attendees in Green Point in relation to the carnival, as well as highlighting the positive and negative aspects of their experience. The research primarily adopted quantitative research approach by using three survey questionnaires (residents, businesses and event attendees) with both closed and open-ended questions. The data were analysed using SPSS version 24 and the findings were visually presented by the use of frequency tables and charts. The general findings indicated that the selected stakeholders were in favour of the Cape Town Carnival to continue being hosted in the Green Point area, although there were some issues that were viewed as the negative impacts of hosting this event. The study’s findings show that the event is perceived positively by the stakeholders even though some had reservations to the idea of the event continuing in the area. Community involvement and enhancing safety and security during event period were some of the recommendations that could see the event continuing flawlessly. The study notes the importance of event organisers to understand the three stakeholders since they contribute to the success of the event. However, even though there are many benefits that are likely to accrue to residents, businesses and event attendees associated with hosting an event of this magnitude, one should not overlook the negative impacts that are potentially connected to such a hosting since this informs how the stakeholders perceive the event
A decision support system framework for testing and evaluating software in organisations
No full textThesis (DPhil (Informatics))--Cape Peninsula University of Technology, 2018.Increasingly, organisations in South African and across the world rely on software for various reasons, such as competitiveness and sustainability. The software are either developed in-house or purchased from the shelf. Irrespective of how the software was acquired, they do encounter challenges, from implementation to support, and use stages. The challenges sometimes hinder and are prohibitive to processes and activities that the software is intended to enable and support. Majority of the challenges that are encountered with software are attributed to the fact that they were not tested or appropriately tested before implementation. Some of the challenges has been costly to many organisations, particularly in South Africa. As a result, some organisations have been lacking in their efforts toward growth, competitiveness and sustainability. The challenges manifest from the fact that there are no testing tools and methods that can be easily customised for an organisation’s purposes. As a result, some organisations adopt more tools and methods for the same testing purposes, which has not solved the problem, as the challenges continue among South Africa organisations. Based on the challenges as stated above, this study was undertaken. The aim was to develop a decision support system framework, which can be used for software testing by any organisation, owing to its flexibility for customisation. The interpretivist and inductive approaches were employed. The qualitative methods and the case study design approach were applied. Three South African organisations, a private, public and small to medium enterprise (SME) were used as cases in this study. A set of criteria was used to select the organisations. The analysis of the data was guided by two sociotechnical theories, actor network theory (ANT) and diffusion of innovation (DOI). The theories were complementarily applied because of their different focuses. The actor network theory focuses on actors, which are both human and non-human, heterogeneity of networks, and the relationship between the actors within networks. This includes the interactions that happen at different moments as translated within the heterogeneous networks. Thus, ANT was employed to examine and gain better understanding of the factors that influence software testing in organisations. The DOI focuses on how new (fresh) ideas are diffused in an environment, with particular focus on innovation decision process, which constitute five stages: knowledge, persuasion, decision, implementation and confirmation. Findings from the data analysis of the three cases were further interpreted. Based on the interpretation, a decision support system framework was developed. The framework is intended to be of interest to software developers, software project managers and other stakeholders, most importantly, to provide guide to software testers in their tasks of testing software. Thus, this research is intended to be of interest and benefit to organisations and academic through its theoretical, practical and methodological contribution as detailed in the chapter seven (conclusion).
In conclusion, even though this research is rigorous, comprehensive and holistic, there are room for future studies. I would like to propose that future research should be in the areas of measurement of software testing. Also, sociotechnical theories like structuration theory and technology acceptance model should be considered in the analysis of such studies
The formulation and validation of PV inverter efficiency under South Africa climate conditions
Get PDFThesis Submitted in Partial Fulfilment of the Requirements for the Degree of Master of Technology: Electrical Engineering (Energy) in the Department of Electrical, Electronic and Computer Engineering
at the Cape Peninsula University of Technology, South Africa.In photovoltaic power systems, the DC/AC conversion efficiency depends on weather conditions causing PV inverters to operate under fluctuating input power from PV modules. The peak efficiency stated by the inverter manufacturers are often used by project designers to estimate how much power PV plants can produce. However, the varying nature of the DC input power to the inverters, occasioned by varying irradiation and temperature, leads to deviations of the actual efficiency from the peak efficiency.
Literature surveys prove that inverter efficiencies must be evaluated against local irradiation profiles to get more precise annual energy yield estimations, since meteorological conditions and solar irradiation profiles vary from one site to another around the planet
Evaluating the quality of the national government self-help housing scheme in the Western Cape; before and after NHBRC involvement
Get PDFThesis (MTech (Business Administration in Project Management))--Cape Peninsula University of Technology, 2018.According to Section 26 (1) of the constitution of Republic of South Africa, everyone has a right to have a satisfactory house to restore and honour the dignity of the South Africans. However South African government implemented several housing programmes to bridge the gap of housing backlog in South Africa. One of the housing programmes that South African government implemented is People Housing Process (PHP). It was approved in 1998 by South African government. South African government shifted focus on the quality of houses and mainly focused on the quantity of houses delivered through the financial year. There have been a lot of quality complaints on PHP. The quality defects are signs of foundation failures, cracks on foundations, water flooding around the houses, water not properly channelling to the drain, cracks on walls, dampness of walls, mould on walls, water seeping through the windows, poorly applied external plaster, incorrect bonding of internal walls to external walls, walls that are not straight walls, sagging ceiling panels, gable not properly filled with mortar, roof structure not properly tied up, sagging roof coverings, roof leaks, sagging roof tiles and ridges, rust on painted iron material, poor quality of blocks used, insufficient cement on mortar mix and peeling off paint. National Home Builders Registration Council (NHBRC) are the custodians of the home building industry. They were excluded from PHP from 1998 till March 2012. NHBRC was approved to inspect PHP house in April 2012. Thus, the aim of the study was to compare the houses that were built before NHBRC involvement in PHP with those that were built after NHBRC involvement in PHP. The sample included 50% of each of the two groups (those in houses built without NHBRC involvement and those built with NHBRC involvement), the research involved at least 50 respondents per group (McMillan, et al 2001:177 – recommends 15 respondents per group). The sample size per group has been put at 50 since the larger the sample the higher the accuracy. The study is classified as quantitative research because it intended to quantify the variation in occurrence, situation, problem or issue; the information was gathered using predominantly quantitative variables and the analysis was geared to ascertain the magnitude of the variation. The findings of the study revealed that the quality of the houses that were built under PHP programme before NHBRC intervention on PHP was not up to standard however the quality on those that were built after NHBRC involvement improved. Therefore it is recommended for Western Cape government to implement the rectification programme which was approved by National Department of Human Settlements in 2009 mainly focusing on houses that have been severely structurally compromised and are regarded as unfit for human habitation as it poses a threat to the health and safety of the occupants (The National Housing Code, 2009: 11-13)
Co-digestion of Cassava Biomass with Winery Waste for Biogas Production in South Africa
No full textThesis (Master of Engineering in Chemical Engineering)--Cape Peninsula University of Technology, 2018.Renewable energy security for the future and better use of natural resources are key challenges that can be concurrently managed by a practical anaerobic co-digestion approach in the production of methane. For this study, co-digestion of cassava and winery waste was investigated for the production of biogas. Cassava biomass is a good substrate for biogas production due to its high carbohydrate yield per hectare (4.742 kg/carb) than most plants. Winery wastes constitute a lot of challenge in South Africa due to high amounts currently being dumped at landfills. Due to the chemical properties of the two substrates, it is envisaged that their co-digestion will produce more biogas than use of a single substrate. Biomethane potential (BMP) tests were carried out in a batch, mesophilic (37 °C±0.5) reactor using cassava and winery waste singly and in combination at a ratio of 1:1 and ran for 30 days. Biogas optimization was also evaluated. The optimal conditions for methane production from anaerobic co-digestion of cassava biomass and winery solid waste using response surface methodology (RSM). The effects of temperature, pH and co-substrate ratios on the methane yield were explored. A central composite design technique was used to set-up the anaerobic co-digestion experiment was determined. Once the optimized values were established, biogas production from co-digestion of cassava biomass with winery waste was investigated using a single-stage 5 L mesophilic batch digester and the microbial dynamics inside the digester during co-digestion of cassava and winery waste in the single-stage 5 L mesophilic batch digester. The samples were collected on days 1, 15 and 30 of the anaerobic digestion period and DNA extracted from them while 16sRNA bacterial sequencing was performed. The results for the BMP tests showed that cumulative methane yield for cassava, winery waste and in combination were 42, 21 and 38 mLCH4 respectively. It was concluded that biogas production from anaerobic digestion was dependent on many factors such as pH, substrate properties and the ratio of different feedstocks used during co-digestion. The results from the optimization study were pH 7, temperature of 35 °C±0.5 and co-digestion ratio of 70:30 cassava to winery waste. The maximum methane yield of 346.28 mLCH4/gVSadded was predicted by the quadratic model at the optimal temperature of 35 oC±0.5, pH of 7 and 70:30 ratio of cassava biomass to winery solid waste. Experimental results showed a close fit but higher methane yield (396 mLCH4/gVSadded) than predicted values as indicated by the coefficient of determination (R2) value of 0.9521. The response surface model proved successful in the optimization process of methane yield. The single-stage 5L mesophilic batch digester with a co-substrate ratio of 70:30 cassava to winery waste produced a total of 819.54 mL/gVS biogas with a 62 % methane content. The study of microbial community dynamics showed the presence of the bacteria that is responsible for each stage of anaerobic digestion. The study concluded that both winery waste and cassava substrates were favourable for biogas production and most underprivileged people in the rural areas with no access to electricity can produce & utilise it
Gold recovery from waste mobile phones PCBs using ammonia thiosulphate leaching and copper cementation process
No full textThesis (Master of Engineering in Chemical Engineering)--Cape Peninsula University of Technology, 2018.The rate of waste electrical and electronic equipment (WEEE) is growing at an alarming rate, especially in countries where markets are saturated with huge quantities of new electronic goods. Printed circuit boards (PCBs) are a substantial portion of the value contained in waste from WEEE although they are only 6% of the total weight. It is reported that WEEE is currently the fastest growing waste stream in South Africa as the general population’s access to electronic goods in the last decade has increased, especially access to mobile phones. PCBs are found in any piece of electrical or electronic equipment and consist of various metals including precious metals such as gold (Au), silver (Ag) and palladium (Pd). It is reported that gold has the highest economic incentive at 15,200 $ per ton of PCBs. The rapid introduction of new and advanced technology into mobile phones has caused mobile phones to have a relatively short life span, 1 to 2 years to be exact. Mobile phones printed circuit boards (MPPCBs) have more Au content compared to computer circuit boards. They contain 350 g/ton Au whereas computer (PC) PCBs contains 250 g/ton. This research project will recover gold from waste mobile phones PCBs pregnant ammonia thiosulphate leach solution using copper cementation. The cementation process is preferred to all the other technologies of metals extraction from solution due to ultrahigh purity metals that can be obtained and to the less consumption of materials and energy. Electronic parts on the PCBs were manually removed using pliers and screwdrivers. PCBs were then cut to smaller pieces of about 2 x 2 m. The pieces were crushed and milled respectively. Some of the particles were recycled back to the crusher to get finer particles. The particles were separated to particles of sizes between 0 and 1350 μm using a shaker. The comminuted fractions of the PCBs were then used in the leaching step. Batch cementation experiments were performed by bubbling N2 in glass reaction vessel with a working volume of 0.5 L. The reactor was connected to a circulating water bath for temperature control. The recovery percentage of gold at various temperatures, agitation speeds and different amounts of copper powder used, was determined while pH was monitored. The temperature was varied at 30 °C, 40 °C, and 50 °C and the agitation speeds at 300 RPM and 900 RPM. Copper powder was added at 0.5 g/L, 1 g/L, and 1.5 g/L. Gold concentrations were measured by atomic adsorption spectrophotometer (AAS). Scanning electron microscope (SEM) and Energy-dispersive x-ray spectrometry (EDS) analyses of the copper powder after cementation (precipitates) were used to determine the surface morphology and to evaluate the quantitative aspect of the precipitate. It was found that the recovery of gold from ammonia thiosulphate leach solution was greatly affected by agitation speed. At an agitation speed of 900 rpm, 40 °C and 0.5 g of Copper powder, 96% of the gold was recovered from the leach solution. The cementation rate increased as temperature was elevated from 30 to 40 °C, but slightly decreased as the temperature reached 50 °C. The change in experimental conditions affected the gold concentration on the precipitate recovered. This study will provide a possible solution to the WEEE problem and more specifically mobile cell phones, in South Africa
