Greening Ndlambe Village
Get PDFIn 1994 the new democratic government of South Africa introduced the Reconstruction and Development Programme (RDP) which was aimed at massive infrastructure expansion. Tackling the housing crisis has been encountered by growing demands for low carbon footprint, reduced use of non-renewable resources and as part of the green agenda. In line with the Sustainable Development Goals (SDGs), the South African government set a variety of objectives aimed at achieving an environmentally sustainable future for all. While South Africa has embraced green economy principles, tested integrated approaches are still to be seen in housing construction. This study sought to explore the greening of Ndlambe green village in the Port Alfred area in the Eastern Cape Province of South Africa. To achieve the study objectives, a qualitative research approach was used, employing the case study research strategy and primary data was collected by means of focus groups. Community members, engineers, environmentalists and town planners constituted the study sample. Secondary data sources were also used in this study, along with field observation. The collected data was analysed using the thematic analysis technique. Findings from the study revealed that community members perceived Green village initiative as important and is required in South Africa given the challenges that are experienced such as energy consumption load shedding, water shortages. The economic value proposition of green building is measured through two different lenses, namely economic profit and social profit. The municipalities must take a leading role in by forming policies supporting environmentally friendly activities, with building being one crucial area. Recommendations from the study proposed that partnerships involving communities, private companies, the government and other various interest groups are imperative in order to accelerating the green building agenda. The government must be challenges to develop sustainable funding solutions for a green economy. Lastly, increased awareness about green building among the society may also drive better acceptability and ultimately, a strong social reputation.Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 202
The legality of anticipatory self-defence against a maritime cyber-attack
Get PDFThis research aims to determine how the principle of anticipatory self-defence, in line with article 51 of the UN Charter, can be applied to the context of maritime cybersecurity. Despite the debates by some scholars to clarify the international law position on anticipatory self-defence in the maritime context, there is no universally accepted legal provision for States to rely on in carrying out anticipatory self-defence against imminent maritime cyber-attacks. This raises the questions concerning the lawful steps States can take in self-defence against maritime cyber-attacks. This research shows the challenges facing States in their bid to comply with the provision of article 51 of the UN Charter to anticipatorily defend against an MCA. The recommendations made are intended to guide States in making policies and mapping our strategies to lawfully tackle the emerging threat of cyber-attacks against maritime security.Thesis (PhD) -- Faculty of Law, School of Environmental Sciences, 202
Social upgrading or dependency?: Investigating the implications of the inclusion of commercial wine farms within South African Fairtrade certification
Get PDFThe South African wine industry is one of the oldest sectors of the country’s economy, beginning in the early years of South African colonialism in the 17th century through the use of slave and slave-like labour. As an industry that has been defined by farm paternalism and dependency, the South African wine industry has had to demonstrate changes from its history of extreme racial and gendered exploitation to an industry that reflects the democratic values of a new South Africa. Ethical certifications are considered one way through which the post-apartheid South African wine industry can demonstrate that it has moved away from its historical practices and is now characterised by practices of decent work and social transformation. An important certificatory label that allows local wine producers entry into global wine production networks is Fairtrade International. While Fairtrade certification is often reserved for small-scale producers, this certification has been extended to large-scale, commercial producers within the South African wine industry despite its history of farm paternalism and dependency. This research asks if this inclusion promotes decent work through social upgrading or if it offers a platform for the continuation of farm dependency under the guise of ‘Fairtrade’. In this study, social upgrading has been defined through a ‘bottom-up’ approach that prioritises workers’ independence as a key means of improvement. Four key pillars are applied as embodying the concept of social upgrading: regular employment with set working hours; legally enforceable worker rights; social protection through collective and individual bargaining power; and non-discriminatory social dialogue that promotes significant socio-economic progression. A key finding of this research is that practices of dependency and paternalism continue on some large-scale commercial farms, despite their Fairtrade certification. Furthermore, the findings suggest that the benefits that farmworkers receive lock farmworkers into their position on the farm with marginally improved conditions and cease if workers depart from the Fairtrade wine farm. This suggests that, at best, this inclusion of commercial farmers within Fairtrade certification appears to create a top-down form of social upgrading that locks farmworkers into their position on the farm with marginally improved conditions and beneath a glass ceiling of development. At worst, this Fairtrade inclusion facilitates a global poverty network through paternalism and dependency under the guise of ‘Fairtrade’. As a result, where meaningful, bottom-up social upgrading may occur on South African wine farms, the study suggests that this is despite the presence of Fairtrade and not a result of it.Thesis (PhD) -- Faculty of Humanities, Political and Interntional Studies, 202
An examination of activism and ‘political listening’ during the year of student protest at the University of Cape Town from 9 March 2015 to 9 March 2016
Get PDFThis study sets out to examine democratic participation in South Africa and the role that ‘political listening’ could play in making participation more equitable. It considers protest action on a South African university campus, which at times not only resulted in significant and swift concessions from the university leadership but also sparked national political action which got an equally swift response from the South African government. It considers the social movement, the RhodesMustFall movement (RMF), as one way in which students can organise themselves to get a better hearing from the University of Cape Town (UCT) management in their attempt to make a meaningful contribution to the university’s micro democracy. This study examines whether the interaction between the UCT management and RMF could be considered ‘political listening’, and the possible role of the Cape Times newspaper within this context of participation. Using data gathered through interviews, written communications, observation and newspaper articles, the study shows that in all of the interactions between RMF and the UCT management, both groups were seldom willing to forego their power to engage in genuine listening. Instead, the two parties guessed at what power the other party might have and acted to reduce that power. It is in this context of guessing at and figuring what power the other party has that listening occurs. Furthermore, the study shows that during the RMF protest, the UCT management viewed their responsibility for the institution mainly through the lens of Private Property Law which framed protest as something to be dealt with by restoring law and order. The study also details the role of the Cape Times newspaper in the interactions between RMF and the UCT management and considers if this role could be political listening. The study is exploratory and demonstrates how political listening could work more optimally in real-life instances.Thesis (PhD) -- Faculty of Humanities, Journalism and Media Studies, 202
Exploring the Correlation of Two Field Tests with Match-Related Performance in Female Premier League Hockey Players
Get PDFBackground: Field hockey is a stick and ball team sport which is comprised of technical and tactical components and requires elevated physical conditioning. Due to the intermittent and complex nature of field hockey, it has become increasingly difficult for coaches to accurately measure the players hockey specific fitness levels. For this reason, various fitness tests have been developed over the years. However, some of the fitness tests utilised to this day do not incorporate movements similar to match situations, and therefore, do not stress the same energy systems in a similar manner to match-play. Hence, the INTER test and Dynamic Yo-Yo test are being utilised in the current study as they incorporate similar movements seen in match-play, and they incorporate varying rest periods. The INTER test is a test that incorporates shuttles, maximal sprints and agility movements. Whereas the Dynamic Yo-Yo test only incorporates shuttles running with differing changes in angles. However, both of these tests have previously only been used in a soccer context, therefore, the results obtained were compared to soccer specific data. Match-related data was compared to current field hockey data. Aim and Objectives: The main aim of the research study was to determine whether the INTER test and the Dynamic Yo-Yo test correlate with match-related physiological demands and physical performance. There were three main objectives of the study. First, to determine and describe the physical and physiological responses in selected cohort off hockey players during match-play, the INTER test and the Dynamic Yo-Yo test. Second, to run correlations between the two field tests and match-play to identify relationships. Third was to identify the differences between the two field tests. Methods: Using a combination of purposive and convenience sampling, a total of 20 field hockey players from the Eastern Cape Premier Hockey League voluntarily participated in the study (age: 22.25 ± 3.16 years; height: 167.3 ± 2.61cm; weight: 59.4 ± 3.87). The participants were monitored during the INTER test, Dynamic Yo-Yo test and the field hockey matches. The following physiological and physical variables were monitored: heart rate, breathing rate, distance and speed. The participants were given a minimum of 24 hours recovery time between field tests and matches to ensure fatigue did not impact results. The monitoring during the field tests and match-play was done by all participants wearing the Zephyr BioHarness and QStarz global positioning system. VI Results: The mean distance achieved in the INTER test and the Dynamic Yo-Yo test both produced a statistically strong relationship to the mean distance achieved in the matches (r=0.82, p=0.000). The time spent in the INTER test and the Dynamic Yo-Yo test compared to the time spent in match-play showed a very weak correlation (r=0.19; r=-0.08). Both the mean breathing rate for the INTER test and the Dynamic Yo-Yo test resulted in a very strong correlations (r=0.8) which was statistically significant (p=0.000). Participants spend on average 72% of match-play at >85% HRpeak compared to the 52% and 78% spent at >85% HRpeak during the INTER test and the Dynamic Yo-Yo test respectively. The INTER test produced a greater number of statistically significant correlations with the combined matches compared to the Dynamic Yo-Yo test. When identifying the differences between the variables measured in the INTER test and the Dynamic Yo-Yo test, it was identified that there were many significant differences. Conclusions: Both the Dynamic Yo-Yo and the INTER test can be used by hockey coaches. However, the researcher would recommend the utilisation of the INTER test, because it displayed stronger, more significant correlations to match-play. The set-up of the INTER test is also more convenient as it can be conducted on the astro turf. While, both tests did have some correlations to match-play, additional tests would need to be included in a testing battery to provide coaches with complete profiles of the players in order to assist in team selections.Thesis (MA) -- Faculty of Health Sciences, 202
An exploration of burnout among health Professions academics employed in Health sciences faculties at a south African university
Get PDFThe label of ‘stress factories’ is becoming a way to collectively refer to higher education institutions due to the changing academic landscape. Academics within health professions face key stressors related to excessive workloads, and insufficient resources resulting in burnout. Some of the most pertinent consequences of burnout include deterioration in physical and mental health, incline in absenteeism and a negative impact on the well-being and performance of students, patients, and organisations. There is a lack of research conducted on health professions academics in South Africa. The overall aim of this study was, therefore, to explore burnout among health professions academic staff who worked within the Community and Health Sciences (CHS) and Dentistry faculties (collectively referred to as Health sciences faculties) at a historically disadvantaged university. The study adopted an online survey design. Participants were selected using simple random sampling. Frequency tables were used to summarise and describe the participants, while correlation analysis was used to test associative relationships. ANOVA was used to test group differences and Scheffé tests were used for posthoc analysis. Ethics clearance was obtained from the Bio-Medical Research Ethics Committee of UWC. Permission to conduct the study was given by the Registrar of UWC. Informed consent was sought from participants for their voluntary participation. Their identities were kept anonymous and responses confidential. Overall findings from the current study indicated that this sample of Health Professional Academics (HPAs) experienced moderate to high levels of burnout, as measured by the Oldenburg Burnout Inventory. No demographic factors were found to correlate with the total score of burnout. Two variables were significantly related to exhaustion, namely the level of qualification and whether participants were studying at the time of completing the survey. Furthermore, nurses and participants currently studying towards a PhD reported significantly higher levels of burnout than the rest of the sample of HPAs. The impact of this study shows HPAs’ experience of moderate to high levels of burnout require interventions to decrease job demands and increase job resources.Thesis (MA) -- Faculty of Health Sciences, 202
The effect of stakeholder management within entities of Nelson Mandela Bay Municipality
Get PDFThe title of this research paper is the effect of stakeholder management within the entities of Nelson Mandela Bay Municipality, a metropolitan municipality in Eastern Cape Province, South Africa. The aim of the research was to investigate the effects of stakeholder management amongst Nelson Mandela Bay Stadium (NMBS), Mandela Bay Development Agency (MBDA) and Nelson Mandela Bay Municipality (NMBM) as the main shareholder to the two entities. The challenges in how municipalities understand the role of internal and external stakeholders and how they are managed effectively continues to face them. Stakeholder management assists municipalities and ensures that key stakeholders are involved in strategic engagements and this helps to improve their decision making in relation to the provision of services. Stakeholder management is considered vital in building fundamental relations among stakeholders. It is thus important for NMBM management to have the understanding of the role, impact and the benefits of effective stakeholder management. Furthermore, stakeholder engagements and good communication can assists to enhance relationships amongst these entities. The study ascertained the role of stakeholder management amongst NMBMB, MBDA and NMBS and conducted and in-depth analysis of the current support system for NMBS. The study also conducted literature review on various frameworks used by South African Municipalities to enable effective communication and stakeholder management within their entities. The study employed a qualitative research design in meeting the primary and secondary aims and focused on the senior management of the three institutions in line with decision making factors that are key to effective stakeholder management. The structured interviews were held with senior managers from NMBM-Economic Development Tourism and Agriculture(EDTA) Directorate, MBDA and NMBS. The study found that there is good understanding of the role of stakeholder management amongst the senior managers. However, it also established that there was a 8 disjuncture in the stakeholder engagements with the NMBM and NMBS and that this may hinder them to deliver on their mandate. Finally the study makes recommendations regarding how best NMBS can manage stakeholder relations with MBDA and NMBM and assesses the value that is created from stakeholder engagement. A framework model that will be inclusive of all stakeholders and that would encourage effective communication must be developed. A study on the role of stakeholder management in Nelson Mandela Bay Municipality is recommended to be conducted.Thesis (MA) -- Faculty of Business and Economic science, 202
The role of climate change on food security in Northern Uganda a case study of Lira district
Get PDFThe study examines the effects of climate change in Northern Uganda to create food security solutions through the improvement of local resilience mechanisms and adaptation devices. The study adopted the interpretive paradigm within the qualitative research methodology as it investigated the subjective opinions of the respondents about the role of climate change on food security in the Lira district. The researcher used non-probability purposive sampling to identify nine officials that possessed knowledge on resilience mechanisms and also interacted directly with individual farmers. The researcher used semi-structured interviews as a tool to collect data and thematic analysis to make conclusions on findings based on the emerging themes. The findings from the study revealed that the four determinants of food security are greatly affected by climate events and these are: food utilisation, food production, food availability and access to food as well as the stability of food supply. Food storage is a problem facing the community of Lira due to extreme climate events. Climate change was found to affect food prices in such a way that when agricultural inputs are bought expensively, it leads the cost of producing crops to increase, which in turn makes food more expensive at the market. The findings also displayed that Lira’s local communities are trying to apply adaptive farming practices to ensure there is an adequate food supply, such as planting a local variety of seeds that withstand the effect of climate change, such as sorghum millet and cassava. Based on the findings, valuable recommendations are offered. These include the government rolling out a national irrigation scheme to ease the use of the drip irrigation mechanism. Also, there is a need for more interventions that support local resilience mechanisms such as the use of agricultural inputs, as these require subsidisation. It emerged from the findings of this study that there is a need for better interventions to deal with flooding. For future researchers, it was found that there is a need to explore the best post-harvest handling methods as well as food storage.Thesis (MA) -- Faculty of Business and Economic Sciences, 202
Reaction of Perrhenate with Phthalocyanine Derivatives in the Presence of Reducing Agents and Rhenium Oxide Nanoparticles in Biomedical Applications
Get PDFA novel alternative route to access rhenium(V)−phthalocyanine complexes through direct metalation of metal-free phthalocyanines (H2Pcs) with a rhenium(VII) salt in the presence of various two-electron reducing agents is presented. Direct ion metalation of tetraamino- or tetranitrophthalocyanine with perrhenate (ReO4−) in the presence of triphenylphosphine led to oxidative decomposition of the H2Pcs, giving their respective phthalonitriles. Conversely, treatment of H2Pcs with ReO4− employing sodium metabisulfite yielded the desired ReVO−Pc complex. Finally, reaction of H2Pcs with ReO4− and NaBH4 as reducing agent led to the formation of rhenium oxide (RexOy) nanoparticles (NPs). The NP synthesis was optimised, and the RexOy NPs were capped with folic acid (FA) conjugated with tetraaminophthalocyanine (TAPc) to enhance their cancer cell targeting ability. The cytotoxicity profile of the resultant RexOy−TAPc−FA NPs was assessed and found to be greater than 80 % viability in four cell lines, namely, MDA−MB-231, HCC7, HCC1806 and HEK293T. Non-cytotoxic concentrations were determined and employed in cancer cell localization studies. The particle size effect on localization of NPs was also investigated using confocal fluorescence and transmission electron microscopy. The smaller NPs (≈10 nm) were found to exhibit stronger fluorescence properties than the ≈50 nm NPs and exhibited better cell localization ability than the ≈50 nm NPs
Novel cationic-chalcone phthalocyanines for photodynamic therapy eradication of S. aureus and E. coli bacterial biofilms and MCF-7 breast cancer
Get PDFNew tetrasubstituted zinc (II) and indium (III) phthalocyanines bearing dimethylamino chalcone group (complexes 3 and 4) as well as their quaternized analogs (3a and 4a) have been assessed for their photodynamic therapy (PDT) of cancer as well as photodynamic antimicrobial chemotherapy activities against biofilms and planktonic cultures of pathogenic bacteria of Staphylococcus aureus and Escherichia coli. Compared to the non-quaternized phthalocyanines 3 and 4, the cationic phthalocyanines 3a and 4a exhibit a higher photodynamic inactivation against the planktonic cells with log reduction values above 9 at a concentration of 1.25 µM. This was attributed to the positive charge which enhances cellular uptake. More interestingly, 3a and 4a show a higher photodynamic inactivation (less than 3% of S. aureus survived) on their biofilm counterparts thanks to their stronger affinity to these cells. 3a and 4a Pcs also exhibited interesting PDT activity against MCF-7 cancer cells giving IC50 values of 17.9 and 7.4 μM, respectively following 15 min irradiation. The obtained results in this work show that the positively charged phthalocyanines 3a and 4a are potential antibacterial photosensitizers that show some selectivity toward the Gram-positive and Gram-negative bacteria as well as MCF-7 breasts cancer cells
