- Description: The idiosyncratic allure of cryptocurrencies, in particular Bitcoin, has attracted widespread, if reticent, attention in the financial markets. Since Bitcoin’s introduction in 2008 there has been a growing interest in digital assets possibly supplanting traditional payment methods. Two conceptual questions raised regarding cryptocurrencies are firstly, whether cryptocurrencies meet the traditional functions of money; secondly, what is the future of cryptocurrencies? This dissertation seeks to examine the future of cryptocurrency by reference to money and monetary policy. The further question, whether cryptocurrencies meet the traditional functions of money, is tested via a combination of theoretical and empirical analysis. The study explores both statistical and empirical models, in illustrative comparative detail, provided by analysis which included ADF and KPSS test models, alongside an ARMA(p,q)-GARCH(1,1) model. Cryptocurrencies present both significant benefits, alongside immense shortcomings. They provide the novel ability to conduct anonymous international transactions on a decentralised platform with lower transaction fees. However, the very nature of that anonymity could provide their downfall as much as they open a market for illicit activities. In addition, cryptocurrency’s significant energy consumption through the mining of cryptocurrencies is of concern to environmentalists. The empirical section of the dissertation consists of a comparative analysis between Bitcoin/USD time series to the Rand/USD time series, with specific attention devoted to the level of volatility of each time series. This was important in determining whether cryptocurrencies fulfil the store of value function of money. The dissertation concluded that Bitcoin/USD time series exhibited identifiable adverse characteristics of autocorrelation and ARCH effects, thus suggesting that Bitcoin/USD is strongly associated with volatility. The Rand/USD signified the same effects although of significantly lesser order than that of Bitcoin/USD. Consequently, cryptocurrencies are seen to act more as an asset than a currency. Nonetheless, cryptocurrencies seem likely to grow as a medium of exchange as more and more businesses gain knowledge of the innovation and seek to adopt innovative ways to become more efficient and follow technology trends. Currently, fiat currencies remain superior in the financial market, simply because cryptocurrencies are perceived not to fulfil the traditional functions of money. However in the future, the market share of cryptocurrencies is likely to increase, and so the future of the financial markets will surely include a coexistence of both fiat and cryptocurrencies, as people’s preferences determine where they feel safe to hold their money.

- Description: This study focuses on an evaluation of communication effectiveness between the school administration office in Nelson Mandela Bay and its representative schools in advancing the business case of school development and heightened learner experience in line with the national development goal. The research uses a qualitative research approach to gather rich insights into the challenges, opportunities and problems that heighten and affect the quality of communication methods, channels and the roles of communication that the interviewed stakeholders representing both the district and schools depict and understand within the communication processes and methods used. Fourteen interviewees were identified using a judgemental and purposive sampling technique. They were identified from the Nelson Mandela Bay district office and schools within the district. Findings from the study reveal that the critical areas of concern include the roles of communication, stakeholder roles in the communication process, methods of communication, and challenges in communication effectiveness. While schools and the district office share the responsibility for providing quality education, it is critical that an effective communication strategy, which embraces computer-mediated communication as a supplementary tool, should be adopted to ensure that this shared mandate could be achieved.

- Description: Time remains a frequently discussed issue in physics and philosophy. One interpretation of growing popularity is the ‘timeless’ view which states that our experience of time is only an illusion. The isolated Universe model, provided by the Wheeler-DeWitt equation, supports this interpretation by describing time using clocks in the conditional probability interpretation (CPI). However, the CPI customarily dismisses interaction effects as negligible creating a potential blind spot which overlooks the potential influence of interaction effects. Accounting for interactions opens up a new avenue of analysis and a potential challenge to the interpretation of time. In aid of our assessment of the impact interaction effects have on the CPI, we present rudimentary definitions of time and its associated concepts. Defined in a minimalist manner, time is argued to require a postulate of causality as a means of accounting for temporal ordering in physical theories. Several of these theories are discussed here in terms of their respective approaches to time and, despite their differences, there are indications that the accounts of time are unified in a more fundamental theory. An analytic analysis of the CPI, incorporating two different clock choices, and a qualitative analysis both confirm that interactions have a necessary role within the CPI. The consequence of removing interactions is a maximised uncertainty in any measurement of the clock and a restriction to a two-state system, as indicated by the results of the toy models and qualitative argument respectively. The philosophical implication is that we are not restricted to the timeless view since including interactions as agents of causal interventions between systems provides an account of time as a real phenomenon. This result highlights the reliance on a postulate of causality which forms a pressing problem in explaining our experience of time.

- Description: The purpose of this research study was to explore the interventions NGOs used in addressing the prevalence of HIV/AIDS along with an exploration of the management and causal factors behind project failures and success. Five districts in the province of the Eastern Cape, South Africa were used in the study. The study had three objectives- the first being to identify the various approaches used to manage HIV/AIDS by NGOs; the second was to consider the influence HIV/AIDS policies on the health sector NGOs and finally the third objective of the study was to explore the monitoring and evaluation mechanism set in place to track progress, or lack of, in HIV/AIDS programs. The research design followed a qualitative methodology and data was gathered from ten participants through semi-structured interviews and supported by a document analysis of existing HIV and AIDS policies from both a national and provincial level which were qualitative. The findings showed that a lack of adequate or delayed funding affected the overall performance of NGOs as well as approaches such as home-based care and educational support programs. Resource mobilization and fundraising ought to be diversified so that there is a committed and varied pool of funds to enable the execution of HIV/AIDS services and programs. The government and other stakeholders should build on local capacity to implement these various programs and build financial, social and organizational sustainability.

In addition, the negative stigma associated with HIV/AIDS has been a looming issue since 2004 which continues to undermine efforts of NGOs in their means to manage HIV/AIDS. The consequences of stigma from the findings are treatment adherence issues and little to no attendance of HIV/AIDS programs provided by the respective NGOs. Effective planning and management along with capacitated staff and volunteers increased the positive outcome of HIV/AIDS programs and services offered by the NGOs. From the study findings, it is recommended that the planning of HIV/AIDS approaches should consider resource planning to avoid abandoning projects midway due to a lack of resources. The management and monitoring of NGOs within the health sector, dealing with epidemics such as HIV/AIDS need to build on flexibility in implementation and have effective risk assessments in place as a contingency, so that corrective action is taken.

- Description: The first study conducted in South Africa of a prominent figure traces back as far as 1939. Since then, extensive research has been done in the field of psychobiography, resulting in a growing interest in this field and evolving into an established research genre in South Africa. Despite the increase in the use of psychobiographies as a research approach internationally and specifically in South Africa, its use is still considered relatively under-utilised and, therefore, the pursuit of further development of psychobiographies in South Africa is required. In light of South Africa’s effort to promote and advance the use of psychobiographies, South African researchers may be motivated to continue studying significant and exceptional lives in South Africa and abroad. Viktor Frankl was selected for this study based on his uniqueness, significance and his interesting life. He is also considered an exceptional individual who has shaped modern psychological thinking. Frankl had written over 40 books on his theory and many studies have been conducted based on his existential theory. Frankl’s contribution to the academic world has been recognised and acknowledged by significant institutions through his own and others’ research. Although much has been written on the life and work of Frankl, none of the literature utilises specific psychological focus and no psychobiographical study of the life of Frankl exists. Therefore, the researcher selected Frankl as the subject for this psychobiography through purposive sampling. The aim of the study was to provide a psychological exploration and description of Frankl’s life against the backdrop of his socio-cultural context. In order to achieve this aim, the researcher employed two psychological frameworks to guide in the description and exploration of his life. The psychological frameworks included Levinson’s life structure theory of adult development and Frankl’s existential theory. The study aimed to describe Frankl’s development with the use of Levinson’s theory while describing how he attained meaning in his life with the use of his own existential theory. Due to the exploratory-descriptive nature of this study, the objective fell within the inductive research approach. The researcher utilised a systematic coding method to arrange the data. The theoretical framework of Levinson’s life structure theory guided the coding system, as well as the key concepts of Frankl’s existential theory. In addition, the researcher utilised Alexander’s guidelines for the extraction of salient data, together with McAdam’s methods and recommendations for managing the data. Lastly, the researcher followed the 12-step method of conducting a psychobiography, as proposed by Du Plessis. Findings from this study found a correlation between Frankl’s life and the eras and transitional periods as theorised by Levinson’s theory. The findings of this study, therefore, support the use of Levinson’s theory with regards to the time frames and its use in understanding Frankl’s development. Also, the researcher found that Levinson’s theory was useful in understanding Frankl’s personality development within his context throughout his lifespan. With regards to Frankl’s existential theory, the researcher found that the use of the theory was suitable in understanding Frankl’s search for meaning. Frankl’s concepts of freedom of will, will to meaning, meaning of life, existential vacuum, supra-meaning, dimensional ontology, the three triads and noö-dynamics assisted in explaining Frankl’s drive to find meaning in his life, take responsibility to attain such meaning and to strive for transcendence beyond his suffering. The researcher found Frankl’s theory useful in explaining his drive, motives, needs and patterns of behaviour within this context. The holistic and integrative approach of the study allowed for an in-depth exploration and description of Frankl’s life and development within his socio-historical context. In addition to contributing to the existing body of knowledge on Frankl, his life and his theory, the study also contributed to the growing field of psychobiographical research. The study acknowledged and highlighted that further in-depth examination of the lives of extraordinary personalities could significantly contribute to psychobiographical studies. Based on the psychological frameworks used to explore and describe Frankl’s life, recommendations are made for future research.

- Description: Many contemporary ICT for development (ICT4D) studies focus on the benefits of mobile phones on the socio-economic development of marginalised communities. For many people in poorly resourced rural areas, one of the significant benefits of mobile phone usage is the expansion of social networks for resources or support. Social capital is one of the concepts that have been found to directly or indirectly influence many aspects of social life, communities and development. In the present study, I explore how mobile phones mediate bonding, bridging and linking social capital in a rural area on the Wild Coast of South Africa, Dwesa. I use individual semi-structured interviews with purposefully selected participants who are mobile phone owners in the area. I employ a thematic analysis to analyse their responses in relation to three dimensions of social capital, i.e. 1) trust and solidarity, 2) social cohesion and inclusion and 3) collective action and empowerment. Like in many South African rural areas, in Dwesa there is endemic poverty, inadequate services and infrastructure and high unemployment. The study found that by increased communication, mobile phones mostly strengthen bonding social capital between close ties who rely on each other for various forms of support. Mobile phones also facilitate the building of bridging social capital among members of various community groups by using WhatsApp group chats and Facebook. The little evidence on the relationship between mobile phone use and linking social capital in the area relates to group networks providing opportunities for interaction between community members and individuals in tertiary institutions and local government positions.

- Description: Despite increasing global recognition of the importance of recreational fisheries, their management largely remains poor. This is because they exhibit unique human-nature relationships and are nested within complex social-ecological systems (SESs). Recreational fisheries in the developing world have large potential for socio-economic development, but are generally underappreciated, in terms of their value and their impact, and are poorly governed. This is particularly concerning as they are highly complex and often compete for resources with dependent artisanal and subsistence fisheries. Developing world recreational fishery SESs are not well understood and present an important research gap for improved governance. The general aim of this thesis was to explore the recreational fishery targeting Polydactylus quadrifilis on the Kwanza Estuary, Angola, and provide context for how managers should approach recreational fisheries in the developing world and in Africa. To do this, the recreational fishery SES was explored using a combination of methodologies including those characteristic of traditional fisheries science, and new methods involving biology, sociology, and economics. The thesis contains an introductory chapter, a chapter describing the background, study area and study species, five data chapters and a discussion chapter. Chapter 3 aimed to investigate the reproductive style of P. quadrifilis. Results identified the species as a protandrous hermaphrodite. Evidence to suggest this included degenerating testicular tissue and the presence of early developing ovarian tissues in transitional individuals. Early-stage oocytes were commonly found in the outer area of male regions and residual late-stage spermatids and spermatozoa were found in the luminal space of ovarian regions, suggesting a process of sex change from the outside inwards. Owing to the species’ reliance on large highly fecund females for reproduction, it is likely that P. quadrifilis will be sensitive to fisheries that target larger individuals, such as trophy recreational fisheries and line fisheries within other sectors. Chapter 4 aimed to investigate alternative methods for adequately describing the growth of P. quadrifilis individuals belonging to either one of two distinct hypothetical life-history pathways: pathway I (‘changers’) – initial maturation as a primary male followed by a sex change to female; pathway II (‘non-changers’) – initial maturation as a male fish with no subsequent sex change, using von Bertalanffy Growth Functions (VBGFs). Other specific objectives included determining the size- and age-at-maturity and size- and age-at-sex-change for P. quadrifilis. Otolith aging revealed rapid growth and early maturation (L50 = 399.2 mm FL, A50 = 1.50 years) and sex change occurred over a wide size (790–1125 mm FL) and age (3–8 years) range. There was strong evidence for partial protandry in P. quadrifilis with several extremely old male fish (up to 22 years) observed in the population. When compared to the conventional model produced for the entire population, there were significant differences in the models for the ‘non-changers’ (LRT, p < 0.01) and their parameters L∞ (full model = 130.8, ‘non-changers’ = 113.3, p < 0.01), k (0.32, 0.44, p < 0.01) and t0 (0.23, 0.43, p = 0.03) in the first approach and the models (LRT, p < 0.01) and their L∞ (‘changers’ = 113.7, p < 0.01) values in the second approach. This suggests that utilising conventional modelling techniques may be inappropriate for the stock assessment and management of P. quadrifilis and, potentially, other sequentially hermaphroditic fishery species. Chapter 5 aimed to assess the sensitivity of P. quadrifilis to recreational C&R within the foreign recreational fishery using a rapid assessment approach. To do this, a number of C&R variables including fight time, air exposure, hook placement, hooking injury, total time of the stress event, river depth and angling method were measured and related to two indicators of fish health and survival – the physiological stress indicators blood glucose and blood lactate concentration and reflex action mortality predictors (RAMPs). Air exposure was identified as a major contributor to motor impairment (Cumulative Link Model: p < 0.01) and fight time was an important contributor to motor impairment via its interaction with air exposure (Cumulative Link Model: p = 0.02). Handling practices appear to be particularly important for larger individuals as fish size was positively correlated with air exposure (Pearson’s r coefficient = 0.41, p < 0.01) and fight times (0.88, p < 0.01). The findings suggest that recreational C&R may result in mortalities directly, via C&R, and indirectly, via predation, and several recommendations were made for best practice. Chapter 6 aimed to assess the direct economic contribution of the recreational fishery for Polydactylus quadrifilis on the Kwanza Estuary. Results indicated that the recreational fishery for contributed significantly to the economy of an area that would otherwise likely receive little external input ($282 054 per four-month fishing season). However, high rates of economic leakage from the study area were identified (58.7%–92.9% of locally spent revenue) and were attributed to the sourcing of lodge supplies, services and staff outside of the local area and the repatriation of profit by foreign business owners. Capacity building within the local community is likely required to develop ‘linkages’ between the local community and the recreational fishery. Greater community involvement in the fishery is suggested to incentivise the protection of recreationally important fishery species and their associated ecosystems. Chapter 7 aimed to investigate the resource user groups involved within the SES. Results illustrated that artisanal and domestic recreational anglers are well-established and are characterised by long histories of participation. The artisanal fishery was highly valued as a source of livelihoods for the local community. Artisanal fishers were eager for involvement in the recreational sector, through the chartering of their vessels, due to the attractiveness of extra earnings. Both recreational and artisanal fishers reported recent decreases in P. quadrifilis catch and anticipated further declines. Domestic recreational anglers appeared to be highly consumptive in their use of the fishery and C&R angling was uncommon. User conflict may be problematic for future management as recreational anglers perceived the artisanal gill-net fishery to be a threat towards P. quadrifilis stocks. In conclusion, the open-access nature of the fishery was identified as the most pertinent threat to its sustainability and likely needs to be addressed. Potential solutions involve offering users the opportunity to purchase access rights (e.g. day permits), thus initiating the concept that users must pay for their use of public resources. Management should aim to protect large female fish due to their increased reproductive value and worth as trophy fish. Thus, C&R angling is likely to be an important interaction between users and the resource. However, angler behaviour will need to be manipulated to promote C&R and minimise C&R-related mortalities. Solutions include angler educational drives and interventions and the implementation of competitive C&R-only angling. Foreign recreational fisheries, although touted as potential ecotourism ventures, will only succeed in improving the lives of local people if they fully integrate the community into the operation of the fishery.

- Description: Despite increasing global recognition of the importance of recreational fisheries, their management largely remains poor. This is because they exhibit unique human-nature relationships and are nested within complex social-ecological systems (SESs). Recreational fisheries in the developing world have large potential for socio-economic development, but are generally underappreciated, in terms of their value and their impact, and are poorly governed. This is particularly concerning as they are highly complex and often compete for resources with dependent artisanal and subsistence fisheries. Developing world recreational fishery SESs are not well understood and present an important research gap for improved governance. The general aim of this thesis was to explore the recreational fishery targeting Polydactylus quadrifilis on the Kwanza Estuary, Angola, and provide context for how managers should approach recreational fisheries in the developing world and in Africa. To do this, the recreational fishery SES was explored using a combination of methodologies including those characteristic of traditional fisheries science, and new methods involving biology, sociology, and economics. The thesis contains an introductory chapter, a chapter describing the background, study area and study species, five data chapters and a discussion chapter. Chapter 3 aimed to investigate the reproductive style of P. quadrifilis. Results identified the species as a protandrous hermaphrodite. Evidence to suggest this included degenerating testicular tissue and the presence of early developing ovarian tissues in transitional individuals. Early-stage oocytes were commonly found in the outer area of male regions and residual late-stage spermatids and spermatozoa were found in the luminal space of ovarian regions, suggesting a process of sex change from the outside inwards.

- Description: Introduction: Sports participation has been associated with a number of benefits to young athletes, outside of purely physical health. One of the key components of a successful sports talent identification and development program is effective coaching. A foundation of effective coaching is the coach’s knowledge which can be developed through formal, non-formal and informal means of education. The majority of coach education literature has however focused on coaches from developed countries. Limited studies have looked at the educational experiences and needs of South African coaches, particularly football coaches. The purpose of the current investigation is to establish Local Football Association (LFA) coaches’ perceptions of their educational backgrounds and what knowledge they deem important to be effective coaches. Method: A mixed methods approach was used in which (n=25) Makana LFA coaches answered a questionnaire with the aim of identifying their educational histories and what their current educational needs were. A semi-structured interview was also implemented in which some of the respondents (n=4) were asked more in-depth questions around the same topics, to create a more complete coaching profile. Results: The questionnaire responses highlighted that only 8% of the coaches possess a formal coaching qualification and all of the coaches work on a volunteer basis. Previous experience as a player is the chief source of knowledge for Makana LFA coaches. Not having enough available time is the main perceived barrier for 56% of participants to seeking out further educational opportunities. Fundamentals of coaching was selected by 56% of the coaches as a key subject they want to learn more about. Findings from the interview demonstrate that participants coach multiple teams and often have to rely on senior players to take up assistant coach positions, as well as managing their time effectively to work with all their teams. Informal education is the main source of information for the coaches which includes asking for advice, reading coaching manuals or having a mentor. The coaches value all 3 forms of education, however non-formal workshops are favoured. This is due to all of the coaches already having some form of informal learning experience and formal learning opportunities being too costly to pursue. A combination of lectures, practical sessions and group discussions is desired as a delivery method of coaching knowledge. Discussion: The level of coaching qualifications in the LFA is low, this may have significant implications for talent identification and development in the Sarah Baartman region. All the coaches are volunteer coaches, who primarily rely on informal means of coaching education. ‘Time’ was indicated to be a major barrier, to coaches seeking out educational opportunities. Coaches indicated that they would benefit from a coaching program if it took into consideration their needs, such as wanting to learn more about interpersonal and intrapersonal awareness. Conclusion: If local coaching programs are to be effective, they must reflect the educational needs of their community.

- Description: This study investigated the causes and effects of the underutilisation of Information Communication Technology (ICT) in the building section of the Amathole Region. The construction industry’s daily processes demand both heavy usages of data and data communication between project participants to meet client requirements. This industry is characterised by inaccurate and untimely communications that often result in costly delays and extensions of the project timeframe. ICT is a potential solution to this problem. The objectives of the study are, therefore, to determine why the above, a technically skilled occupational government institution in the Eastern Cape, does not employ ICT efficiently and optimally during this time of the looming global fourth industrial revolution. The literature review detailed the causes of and impact level of ICT’s utilisation and its potential benefits. For data collection, the researcher held unstructured interviews with a Chief Quantity Surveyor, Chief Architect, Engineer, Building Inspectors, and a Quantity Surveyor who dealt directly with construction projects. The key findings revealed that a lack of understanding of existing and newly available ICT software and hardware technology existed amongst certain senior officials within the building technology. The previously alluded, combined with the fear of the inability to learn and apply such new technology, has led to a culture of resistance to change from these more senior officials to utilise applications such as AutoCAD. The above-mentioned resistance, has also triggered the prevention of access to and lack of ICT resources, training, and inadequate funding, thereby eventually resulting in the underutilisation of ICT within the whole building section. This change also adversely affects all officials, especially the junior officials who have graduated using the most recent ICT technology during their studies. The researcher deduced, from the above findings, that adequate change management and continuous development, combined with the allocation of proper resources, would be necessary for all staff members. It was also determined that investments had to be made in the ICT equipment through the provision of a sufficient budget in the building section at AR.

- Description: Health care facilities in the South African public sector have, over time, become notorious for poor service delivery, peppered with issues of poor governance, weak administration capabilities, and ailing working conditions. Often, the consequence hereof is a loss of good talent to both the private sector and health sectors abroad, all the while placing more strain on institutional service delivery capabilities. To achieve the United Nation’s Sustainable Development Goal (SDG) of Universal Health Coverage (UHC) by 2030, the strengthening of health systems is critical. The purpose of this study is therefore to offer supportable solutions to improve and maintain a sustainable rehabilitation service in the Nelson Mandela Metro through successful retention of staff. The aim of this study then is to investigate the influence that Human Resources (HR) processes, working conditions and leadership have had on retention of staff. A review of the available literature was conducted on possible factors that contribute to the problem and the solutions thereof. The study population included all staff that worked in rehabilitation service departments in the public health institutions in the Nelson Mandela Metro, namely; physiotherapy, occupational therapy, speech therapy and audiology. The sample constituted n=51 respondents. Data was collected via a questionnaire as the selected measurement tool. The data was analysed using the statistical data analysis software system, TIBCO Statistica (version 13), and selected methods for quantitative data. The results of the study showed that only HR processes were significantly and positively (r = 0.67, p < 0.05) related to retention. It means that satisfying the HR needs of this population is most likely to retain their employ and improve and maintain rehabilitation service delivery in the selected metro. Descriptive statistics of all the variables were also calculated and reported on. Lastly, the managerial implications of the study findings were reported on.

- Description: To remain competitive, organisations must continuously adapt to their global environment. Hill, Schilling and Jones (2018:81) identifies various key factors with human capital being a key contributor to attaining a competitive advantage. Against this background, the focus of this study was to investigate the organisational factors that impact on the success of employee retention strategies. The drivers in the model adopted for this study included: staff compensation, organisational culture, leadership, career development, staff empowerment and value-based staff recognition. The purpose of the study was to understand the perceived effectiveness of retention strategies in South African businesses. An overview of the literature was provided whereby the importance of retention as a source of competitive advantage was highlighted. The literature identified six strategies that would reduce turnover, and thus have a positive effect on the perceived success of staff retention. The six independent variables, namely organisational culture, staff empowerment, value-based staff recognition, staff compensation, leadership and career development formed the foundation of the theoretical framework.The research paradigm adopted for this research was positivistic and the methodology was quantitative research. The primary data was collected via a survey in a self-administered questionnaire format. Non-probability convenienceand snowball samplingwas used,and the questions were formulated from existing measuring instruments in the literature. A sample size of 237 respondents was surveyed.The statistical data analysis methods included frequency distribution, correlation and multiple linear regression to evaluate the relational aspects of the model to measure the determinants of the success of staff retention.The findings of the study revealed that five variables, namely strategies related to value-based staff recognition, staff compensation, organisational culture, leadership and career development, were significantly related to employee retention. A positive relationship between all the variables and retention was proved in this study.

- Description: Background:The complex nature of healthcare systemsoftenresultsinthe emergence of context-specific barriers that limit the ability for healthcare stakeholders to ensure safe and effective care delivery. In low-to middle-income (LMIC) countries, such as South Africa (SA), limited financial, material and human resources coupled withpoor infrastructure and poor public health determinants, includingpoverty andpoor education, affectthe ability to maintain andimprove on quality care outcomes.Understanding what different stakeholders perceive as barriers, and if these barriers are understood at different levels, is therefore important when attempting to mitigate the risk for unsafe or inefficient care delivery. Human Factors and Ergonomics (HFE) adoptssystems and participatory approaches for the exploration, analysis, and design of socio-technical systems to optimize both human wellbeing and system performance.The barriers to safe and effective healthcare delivery, from an HFE perspective, are not known in the South African context, particularly in parts of the Eastern Cape Province. Elucidatingthesebarriers, even if self-reported,may guidefuture efforts aimed at mitigating risks.The purpose of this study, therefore,wasto explore and highlight the perceived systemic barriers to local and national healthcare delivery, within the Sarah Baartman District in the Eastern Cape Province of South Africa.Methods: Ashort discussion aimed at introducing HFE and components of the Work Systems Model, followed by a survey that captured participant demographics, job characteristics, the perceived national and local systemic barriers, and proposed solutions, was administered withhealthcare stakeholders from 14 primary healthcare facilities and 1 department office within the Sarah Baartman District.Participants (n=120) included management, pharmacy, administration, maintenance, community-and home-based care and nursing staff.Data from the surveys were thematically analysed and categorised according to components of the work system model (Carayon, 2009) and respective workgroup.Results: The findings revealed many overlapping,systemic barriersthat includedshortages of staff, poor management and leadership, a lack of equipmentand basic necessities, poor infrastructure, patient complexity,and high workloads. The results further indicate that the way in which the reported barriers affect worksystem interactionsand performance are unique to different workgroups. Stakeholders iiproposedthat,among others, the absorption of contract workers, the provision of training and adequate human and medical resources and the maintenance of facilities may mitigate the barriers and improve healthcare delivery.Conclusion: The findings highlight a myriad of perceived systemic barriers perceived in the Sarah Baartman district, some of which were fundamental for the effective function of any healthcare system. These barriers may have wide-spread implications for stakeholders at all levels, ultimately affecting the performance, satisfaction and safety and the quality of care. It is especially important to consider these barriers in light of the COVID-19 epidemic, which emerged throughout this study and the major threat it presents to South African healthcare systems. Future research should aim to explore how these barriers interact to contribute to processes and outcomes, as well as explore the perceptions at provincial and national levels in order to better identify areas and strategies for improvement.

- Description: The World Alzheimer Report statedin 2016 that approximately 46.8 million people were living with dementia and this figure is expected to triple by 2050. Alzheimer’s Disease was discovered to be a precursor to dementia in 1976 and since then efforts to understand Alzheimer’s have been prioritized. To date, there are very few effective forms of treatment for Alzheimer’s, many are known to offer only mild calming of the symptoms and have side effects such as diarrhea, nausea, loss of appetite and sleep disturbances. This has been due to lack of understanding on how Alzheimer’s is caused. With the two main hallmarks of the disease now being more understood it has opened the doorway into the discovery of new treatments for this disease. This study focuses on the hallmark involving the aggregation of the β-amyloid protein to form plaques surrounding the neurons of the brain. Copper, Zinc and Iron have also been found in high concentrations in and surrounding these plaques. This study focused on the screening of the South African Natural Compound database (SANCDB) to discover hits that have potential destabilizing action against the Beta-amyloid aggregate. If one of these compounds could prove to have destabilizing action on the aggregate it could open the doorway to new potential forms of treatment. Over 700 SANCDB compounds were docked, and the top hits were taken to molecular dynamics to further study the interactions of the compounds and the aggregate. However, the hits identified had strong binding to the aggregate causing it to become stable instead of the desired effect of destabilizing the structure. This information, however, does not rule out the possibility of these compounds preventing the formation of the aggregates. Further, interactions of copper with β-amyloid and copper were determined by solubilizing the aggregate and introducing copper ions in a dynamics simulation. Possible interactions between copper and the methionine residues were visualised.

- Description: Marine ecosystems are experiencing rapid changes due to climate change. The associated temporal and spatial changes in resource distribution impacts on the foraging behaviour of marine top predators. If these changes negatively affect the ability of marine predators to forage efficiently, there may be dire consequences for their populations. However, evidence of foraging plasticity during adverse conditions, or generalist foraging behaviour, can allow inference about the resilience of species to environmental change and provide essential knowledge towards effective and proactive conservation measures. I examined plasticity in the trophic ecology of 12 marine predator species breeding on Marion Island, southern Indian Ocean, over three years (2015 – 2018), a period characterized by pronounced environmental variability. Firstly, I correlated behavioural states inferred along the GPS tracks of incubating wandering, grey-headed, sooty and light-mantled albatrosses to environmental variables that are indicative of biologically productive oceanographic features. Secondly, I analysed δ13C and δ15N blood values in 12 marine predator species (the afore-mentioned albatrosses as well as king, gentoo, macaroni and eastern rockhopper penguins, northern and southern giant petrels and Antarctic and sub-Antarctic fur seals) over two seasons: summer and autumn. My results revealed that the foraging behaviour of all the species is, to some degree, either plastic (temporally variable isotopic niche) or general (large isotopic niche which remained similar over time), except for the king penguin (small isotopic niche which remained similar over time), a known foraging specialist. Furthermore, despite their dynamic foraging behaviour, resource partitioning among the predators was maintained over time. Due to the ease and relatively low cost of collecting tissues for stable isotope analysis it has the potential to be a powerful tool to monitor the trophic ecology of marine predators. I thus used my simultaneously collected dataset of GPS tracks with the stable isotope blood compositions to investigate some of the assumptions underlying the inferences made from marine predator δ13C and δ15N blood values. I reconstructed species- and guild- specific δ13C and δ15N isoscapes for eight seabird species. Following this, I coupled individual-based movement models of northern giant petrels with global marine isotope models to explore the sensitivity of tissue δ13C values to a range of extrinsic (environmental) and intrinsic (behavioural, physiological) drivers. My results demonstrate the strong influence of reference isoscapes on the inference of stable isotope compositions of marine predators. Furthermore, I show that caution should be used when using non-species-specific or temporally inaccurate isoscapes. I furthermore demonstrate that biological interactions, such as competition for food resources, either past or present, as well as spatio-temporal distribution of food patches strongly influence the foraging behaviour of marine predators. These findings highlight the importance of integrating biological interactions in species distribution models which are used to predict possible distributional shifts of marine predators in the context of global changes. My thesis further developed previously available methods and presents a novel approach to investigate sources of variance in the stable isotopic composition of animals’ tissues.

- Description: This study identifies and analyses the effectiveness of the tax tools available to the small businesses that make up more than 99 per cent of all businesses in the United States and the state of Oklahoma through an extensive investigation of the small business resources offered by federal and state government agencies, higher education institutions and the professional accounting community. The study uses numerous measurements in order to acquire multiple perspectives and relies on the examination of government websites and documents, interviews, experiments, surveys, and questionnaires to determine the existing small business tax tools and their limitations. The research offers an in-depth analysis of the facts and limitations of the small business services offered by the Internal Revenue Service (IRS). The IRS is determined the largest source of small business tax tools, but limitations plague their effectiveness. Higher education is found guilty of not providing small business education in business or accounting disciplines, leaving college graduates ill-prepared to assist small businesses. Higher education is urged to implement a small business accounting curriculum that couples field experience with classroom lectures and textbooks. This study finds the accounting profession apathetic with regard to informing small businesses of accounting services and presses certified public accountants to be more involved in the education of future small business accountants. The study concludes with recommendations to reduce the small business tax burden by improving the existing small business tax tools.

Morgan–Javis (2015) further maintains that in 2011 decentralisation was launched with a view to decentralise health services from the Ministry of Health (MOH) to the Ministry of Local Government and Chieftainship Affairs (MOLGCA). There has been increased attention on the restructuring process of the health sector reform but little priority has been given as to how to decentralise key human resources functions. A guiding policy was developed and endorsed in 2014, but still excludes how these human resources functions are to be decentralised. Centralised human resources services is an impediment in the transformation process of improved health care services for the Basotho Nation (Morgan–Javis, 2015).Ulrich’s (1998) HR model formed the theoretical model of study.This study aimed to explore how the Human Resources (HR) functions support the decentralisation in the Ministry of Health.

- Description: The dissertation examines the Ugandan labour dispute resolution system by undertaking an analysis of international labour standards and a case study of South Africa’s labour dispute system. The study pronounces the legislative provisions of the Employment Act and Labour Disputes (Arbitration and Settlement) Act that exist for the effective and efficient resolution of labour disputes through an alternative dispute resolution (ADR) system. The study contends for the provision of a proactive and expeditious dispute resolution system that helps to resolve labour disputes in the most effective and efficient manner, without necessarily having to resort to the courts. The dissertation further examines the provisions of relevant international labour standards on labour dispute resolution to ascertain their adequacy as part frameworks that apply to Uganda’s obligation to provide ADR systems that respond to the needs of the labour relations community. The study contends that ratifying particular ILO conventions creates obligations upon a country to comply and apply provisions of these conventions in national legislation. It is further argued that by having ratified those international labour standards that provide for ADR, Uganda assumes specific obligations under international law, enjoining the country to provide the required ADR system of conciliation and arbitration, which is reliable and trusted by the countries citizens. A case study of South Africa is adopted with the primary focus on whether Uganda can learn from South African’s ADR system which is arguably more effective and efficient. South Africa has a labour dispute resolution system that has influenced majority of the Southern African Development Community (SADAC) law, hence prompting this study to borrow its ADR system predominantly the Commission for Conciliation Mediation and Arbitration (CCMA). Despite the differences between Uganda and South Africa, the study also indicates fundamental similarities. Preferably, disputes should be resolved at conciliation level, resulting in the minority of disputes being referred to arbitration or the Industrial Court. This is far from the reality of the situation in Uganda. The study acknowledges that the Labour Disputes (Arbitration and Settlement) Act and Employment Act have put up provisions to establish a fast and effective labour dispute system, however, the gap exists at implementing these effective provisions in the Labour Disputes (Arbitration and Settlement) Act and the Employment Act. These lacunae in implementation make the attainment of an effective and efficient labour dispute resolution difficult. For this reason, the author proposes several remedial interventions in line with international labour standards and lessons from South Africa’s system that look to the future and the continued provision of fast, effective, and user-friendly ADR services. For Uganda to solve successfully apply these remedies, a strong political will as well as concerted efforts from all role players in the labour relations community is required.
