- Description: Introduction: School going adolescents have been identified as a group that is at risk of obtaining insufficient sleep due to shortened and irregular sleep, all of which can affect the overall wellbeing of adolescents. While there has been extenstive research on adolescent sleep around the world, research in South Africa has been limited. Of the research performed in this context, most has been conducted in city or urban contexts, but there has been comparatively less research on sleep in adolescents from rural and township areas. Therefore, this study focused on characterising and comparing the sleep-wake behaviour of late adolescents from selected rural and township areas in Alice in the Eastern Cape of South Africa. Methods: An adapted version School Sleep Habits Survey (SSHS) was included in the study and assessed demographic, academic, sleep-wake behaviour, lifestyle, and behavioural information of adolescents from rural and township schools in and around Alice. The survey was distributed physically to all the learners from four co-educational rural and township schools. The responses to the survey were analysed with descriptive and non-parametric inferential statistics, as all data were not normally distributed. Results: A total of 123 learners completed the survey. All the participants were in Grade 12, aged 16 to 26 years (median =18, IQR= 18-19) from rural (n=28) and township (n=95) schools. Seventy-four female and 49 male learners participated in the study. Within the sample, there were also a group of participants who were not adolescents (n=22) whose age ranged between 20 and 26. Reported sleep during both the week and weekend (7hours) was lower than both the recommended duration for adolescents and their own self-reported sleep need of a median of 8 hours and 14 minutes. Bedtimes were significantly earlier on weekdays than weekends. The need to do homework and feeling sleepy were cited as the main reasons for going to sleep during the week and the weekends. Wake times on weekdays and weekends did not differ, with most learners citing being woken up by an alarm clock as the main reason for waking during both weekdays and weekends. Most learners (n=47; 38%) reported walking to get to school, while 41 (33%) relied on public transport to get to school. There were no significant effects of gender or of being rural and township scholars in relation to their sleep variables. Comparisons between non-adolescents and adolescents revealed that non-adolescents reported sleeping longer (7 hours and 30 minutes) compared to adolescents (7 hours) than adolescents did on weekends. As a group, the learners in this sample were morningness-orientated in terms of chronotype, presented with low day time sleepiness, some evidence of sleep-wake behaviour problems and of depressive mood symptoms. Nearly half (n=53; 43%) the group reported napping occasionally on school days. In terms of caffeine consumption, just over half (n=64; 52%) of the learners reported never consuming caffeinated substances such as soda, coffee, or tea. Conclusions: The reported sleep duration of learners in this study was consistent on both the week and weekend but was shorter than the recommended 8-10 hours for late adolescents. While learners in this sample reported early bedtimes, sleep was likely curtailed by the early rise times due to the contextual constraints where scholars had to commute, by either walking or taking public transport, to make the early school start times. There was a high prevalence of sleep disturbances in this sample however, the effects of this (increased daytime sleepiness) were lower which can be attributed to low reported prevalence of caffeine consumption combined with the high prevalence of reported day time napping on school days and weekends. While only a snapshot, the results of this study support previous research that has highlighted the challenges that many adolescents across the globe experience when it comes to obtaining enough sleep. The results of this study highlighted the need for more research to understand the sleep-wake behaviours of learners and their lifestyles more objectively. Given the early starts for many participants in this study, interventions such as delaying school start times may help to improve the amount of sleep that learners get during the week. However, extensive consultations would be needed to ensure that systemic changes that aim to improve sleep of adolescents are applicable for the context of rural and townships areas in South Africa. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2022

- Description: Patient Safety Incidents (PSI) are a frequent occurrence within the South African public healthcare system wherein a patient is unnecessarily maimed, harmed, killed, or put through significant trauma, emotional or physical. These incidents have a significant impact on the performance of the system and the well-being of individuals involved. Often PSI are the result of multiple system failings that provide the necessary preconditions for the PSI to occur. Thus, to provide appropriate patient safety recommendations to address and aid in the prevention of future PSI it is necessary to apply a systems approach to PSI analysis. A systems approach supports a ‘bigger picture’ view of an incident which includes looking beyond the immediate causes of a PSI and taking the different levels of the healthcare system into consideration during incident analysis. Human Factors and Ergonomics (HFE) is at its core a systems discipline and has been successfully applied to multiple fields including healthcare. HFE offers multiple incident analysis tools grounded in systems theory. The Life Esidimeni incident, a PSI that resulted in the death of 144 MHCU, is the biggest PSI in recent South African history and is therefore an important potential case study for the application of HFE systems tools within the South African healthcare context (an area that is lacking in existing literature). The objectives of this research were to (i) Systematically uncover the causal factors that led to the outcome of the of the Life Esidimeni incident; (ii) Identify critical faults, and gaps within the healthcare system that led to the Life Esidimeni PSI; and (iii) Provide proactive recommendations for future prevention of PSI. To fulfil these objectives a descriptive case study research method design was adopted using a qualitative systems-based tool, AcciMap. The application of AcciMap to Life Esidimeni enabled both the sharp end and blunt end causal factors that contributed to the outcome of the incident to be identified. Importantly this provided insight into the critical faults and gaps of the South African public healthcare system. The results of the AcciMap indicated that there were four main broad systemic faults in the system. These broad areas were categorized as key themes, which include: (i) competency, (ii) safeguards, (iii) time pressures, and (iv) vertical integration. From these key themes recommendations aimed at addressing the critical faults and gaps in the system and preventing future PSI were made. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2022

- Description: This is an autoethnographic and performance-based study on the correlation between indigenous and modern cultures. It discusses the influence of globalisation, modernity, and of the Chopi people migrations to Maputo, the main city of Mozambique and to gold and platinum mines in South Africa, on timbila music. Timbila is both the name of a musical instrument (xylophone) and of a cultural manifestation, practiced by the Chopi people from Mozambique. It is one of the most documented music and dance cultures in Mozambique and was proclaimed as a masterpiece of the oral and immaterial heritage of humanity by UNESCO in 2005. The oldest references by Father Andre Fernandes date from the 16th century. However, the most well-known timbila sources were written and recorded by Hugh Tracey, the founder of the International Library of African Music (ILAM), from 1940s. All these sources were based on traditional timbila music. None refers to contemporary timbila music, which is a mixture of timbila with Western musical instruments. The research is thus based on both historical and is new research to understand the role of the phenomena mentioned above to the reinterpretation of timbila music over the time. Performance based and autoethnography methods were selected because of my role as a pedagogue of the music and culture of timbila, allowing me to express my knowledge on this cultural expression. Literature review and interviews are the two procedures of data collecting employed to get an understanding of the research methods; the phenomena of modernity, globalisation and of the Chopis migration for the searching of better living conditions in Maputo and South Africa; and the approaches of different scholars who have written about timbila. The use of these methods and methodologies, allowed me to conclude that, Chopis migrations, modernity and globalisation has allowed the emergence of a modern version of timbila music; internationalisation and dissemination of this musical expression; and contributes to the extinction of traditional timbila orchestras in Zavala. Despite considerable studies on timbila music and culture, this thesis is important and pioneering, from the perspective of studying the influence of Chopis migrations, globalisation and modernity on timbila and is one of the few sources that approach the contemporary timbila music. , Thesis (MMus) -- Faculty of Humanities, Music and Musicology, 2022
