Item Could Not Sing in the Dead Heat: Liner Notes Under the Sun(University of the Witwatersrand, Johannesburg, 2022) Ramphalile, Molemo Karabo; Schuhmann, AntjeOn the one hand we place blackness as a historical if inconsistent category inextricable with morbidity, disfavour, depravity, mystery, wretchedness, penumbra, opacity or absence of light, and the abyssal – in both secular and religious metaphysical symbolism. On the other hand we place space as a historical and physical category denoting area, range, clearance, scope, volume, expanse, lacunae, aperture, margin, and in its instance as verb – opening, arranging, ordering, placing, separating, and locating; which in cosmography, geography and cartography finds its varied imaginative and applied interpretation. We coalesce what is in both hands in order to envisage how blackness persistently becomes and comes to be the extractable property of sub-Saharan Africans. Through various ontological-cosmographic- geographic designations such as Torrid Zone, ‘land of the blacks’ or even terra nullius, we encounter visualisations of a territory and expanse that is always either completely devoid of people or inadequately peopled, that is, the territory whence blackness as inextricably embodied (or fleshened) exists and is cultivated. Blackness: not only does it determine our modes of being, or non-being, in this world, but for us in this study, it is also an experiential, experimental and analytical lens permitting the suggestion and scribing of historical narratives and discourses that centre the inveterate decentring of blacks. In the tradition of liner notes, this study is written in a performative relation to the subject or object at hand; there under the sun, in the dead heat.Item Voiding cystourethrography in the renal pre-transplantation workup: an essential investigation?(University of the Witwatersrand, Johannesburg, 2022-10) Sofianos, Zelia; Rajkumar, Leisha; Lucas, SusanINTRODUCTION: Due to resource constraints in the South African public healthcare sector, patients with End-Stage Renal Disease (ESRD) are eligible for renal replacement therapy only if they are also found to be eligible for renal transplant. AIM: The aim of this study is to document Voiding Cystourethrogram (VCUG) findings in potential renal transplant candidates to assess the contribution of the VCUG as a standard investigation in the renal transplant workup. METHODS: Of the patients who underwent VCUG in Klerksdorp/Tshepong Hospital Complex (North West province, South Africa) from 1 January 2019 to 31 March 2020, 85 patients were included in the study and their VCUG findings retrospectively analysed. RESULTS: The mean age was 40.0 years (range 21-62 years), with males constituting 57.7% of patients and females 42.3%. Lower urinary tract abnormalities were identified in 24.7% of patients, some of whom had more than one abnormality. Of the total abnormalities, VUR (vesicoureteral reflux) accounted for 15.3%, bladder diverticula for 5.9%, urethral strictures for 3.5% and a significant post-void residual volume for 4.7%. No comorbidities were found to have a statistically significant association with the presence of VCUG abnormalities. CONCLUSIONS: To ensure that patients with End-Stage Renal Disease are adequately prepared for renal dialysis and potential renal transplant, and that their comorbidities and lower urinary tract are optimised should abnormalities be identified on VCUG, the VCUG remains an essential investigation in the renal transplant workup.Item Adherence to the Standard Treatment Guidelines in managing patients with hypertension at Chiawelo Community Health Centre, Gauteng, South Africa(University of the Witwatersrand, Johannesburg, 2022-04) Dawduth, Nikkeeta; Torlutter, MicheleBackground: Hypertension is a highly prevalent chronic disease, causing significant morbidity and mortality and is poorly managed and controlled in primary care, with only 24.5 to 56% of patients being controlled. Aim: The aim of the study was to determine health care worker adherence to the Standard Treatment Guidelines in managing hypertensive patients in primary care. Methods: The study was conducted at Chiawelo Community Practice Johannesburg. A retrospective file review was done on 261 hypertensive patients and information extracted to determine whether health care workers performed correct baseline tests at diagnosis; correct investigations were done on ongoing basis; lifestyle modification was addressed; and correct pharmacological therapy was prescribed and titrated. Data analysis included descriptive statistics and bivariate analysis. Results: A total of 77% of participants were female and 23% were male of which 80.5% participants had co-morbidities. Patients were treated by a doctor in 97% of cases; 84.3% by clinical associate, and 0.6% by a nurse only over time. Baseline findings recorded in the file at diagnosis were: weight 65.9%, height 73.2%, potassium 32.2%, BMI 50.2%, abdominal circumference 51.7%, and urine dipsticks 47.9%. Vitals and investigations recorded in the file: BP 99.6%, weight 19.5%, blood glucose 86.6%, creatinine 95.4%, eGFR 94.3% and urine protein 3.4%. Lifestyle modification was recorded for 23.7% and medication adherence was checked and recorded for 36.4% of patients. The correct antihypertensive medications were prescribed in 96.5% of patients but titrated correctly in only 73.5% of patients. 52.8% of patients were controlled on treatment. Conclusion: Adherence to guidelines by health care workers was suboptimal and several aspects of care warrants quality improvement processes.Item Financial inclusion through WhatsApp banking in Johannesburg(University of the Witwatersrand, Johannesburg, 2022) Miller, Jade Rowan; Balabanoff,GarthApproximately three billion people will use mobile banking by 2024. Mobile devices and widespread Internet access are helping to boost mobile banking's popularity. Retail banks can now offer their customers even more convenience with mobile banking applications like WhatsApp. Consumers and financial institutions have embraced advanced technologies, including mobile banking, in recent years. Social media, mobile banking and new ideas like WhatsApp banking have made it easier for people to do business. Mobile banking is now possible thanks to high smartphone penetration and technological advancements. The fourth industrial revolution will continue to exponentially transform the modern economy. Globalisation has forced banks to open new channels to remain competitive in today's market. Banks have had to cut costs and improve their financial position by introducing new products and services. Mobile banking has grown rapidly globally due to the rapid development of information technology. Due to multi-channel distribution, most banks now have a global presence with cross-border customers. A quantitative approach was taken to examine factors that may influence behavioural intention to use WhatsApp banking in the context of financial inclusion. A questionnaire was used as the primary data collection instrument. The survey was conducted using an online questionnaire distributed to people living in Johannesburg, South Africa. The study adds to the body of knowledge by identifying factors that influence WhatsApp banking adoption, particularly in developing countries. The Technology Acceptance Model by Davis (1985) was used to investigate behavioural intention to use WhatsApp banking. My findings show that perceived trust, banking inclusion, perceived usefulness and awareness all play a significant role in WhatsApp banking adoption. Managers in financial institutions should focus on increasing consumer trust across all age groups to increase customer comfort with non-traditional banking platforms in general and thus increase financial inclusion. This is crucial because ix WhatsApp banking has the potential to bank the unbanked and underbanked while also increasing financial inclusion.Item The nexus between the World Governance Indicators’ scores on corruption and the financial performance of SOEs in South Africa(University of the Witwatersrand, Johannesburg, 2022) Mdluli, Mthokozisi XolaniSouth Africa, according to Crompton et al. (2017), is dealing with a triple threat of poverty, inequality, and unemployment. As a result, the government is faced with the task of meeting all of these urgent demands while being hampered by a tight budget and weak economic growth. Procurement is a critical component of the government's service delivery system, and it has been utilised as a policy tool to achieve the government's socioeconomic goals (Badenhorst-Weiss, 2012). Government spending is required to be thoroughly thought out on this basis before any public funds are spent. As a result, government expenditure should be monitored and evaluated as part of the architecture of all government-led projects (Crompton et al., 2017). SOEs (State-owned entities), also known as public entities, are tasked with specific responsibilities by the country's constitution in order to assist the state in fulfilling its mandate (Ovens, 2013). In line with international trends, South Africa has implemented corporatisation, or the transfer of state assets or agencies into state-owned corporations, in a number of areas to encourage more effective and efficient service delivery. Increased public procurement is the result of this. Public procurement involves a large amount of money, which has attracted corruption because of the scale at which it is carried out (Crompton et al., 2017). According to the South African Department of Commerce and Industries, government purchasing power contributed between 15% and 25% of GDP in 2016 (Makube, 2016). Makube (2016) estimates that, between 2013 and 2016, public infrastructure investment in healthcare facilities, schools, water, sanitation, housing, and electrification totalled R827 billion. As a result, the SOEs have been subjected to outside intervention, as well 2 as possible wrongdoing and corruption. According to recent media reports, the country has unacceptably high levels of corruption (Mantzaris, 2016). Understanding how this corruption affects the workings of SOEs is important if the country wants to attempt to start addressing this scourge. Therefore, this study seeks to investigate the relationship that exists between a known measure of governance in a country, namely the World Governance Indicators and the financial performance of SOEs in South AfricaItem The adoption of efficient technology in emerging markets within State Owned Bank in South Africa(University of the Witwatersrand, Johannesburg, 2022) Malatji , Jaftha Sechube; Dladla, PholileThis study aims to explore the adoption of efficient technologies in a South African state-owned enterprise (SOE) or state-owned bank (SOB), specifically investigating the factors that affect how efficient technologies are adopted, the challenges that come during the adoption phase, and the advantages that result from successfully adopting efficient technologies. The research study applied a qualitative research design and used interviews with open-ended questions to collect data. The findings reveal a complex landscape influenced by various elements such as communication, leadership, organisational culture, and operational efficiency. The study highlights the importance of technology adoption within an SOE or SOB. Based on the findings, recommendations were formulated that can be used to enhance how the South African State-Owned Bank can manage the adoption of new technologies efficiently while reducing the risks connected with technology adoption. Despite certain limitations, the study provides valuable insights into the intricate dynamics of new technology adoption in a traditionally oriented country like South Africa.Item Leadership style and supervisory behaviour on employee wellbeing and performance at two Retail Banks in South Africa(University of the Witwatersrand, Johannesburg, 2022) Harris, CandyThis study investigates leadership style and supervisory behaviour on employee wellbeing and performance at two retail banks in South Africa. The study aims to contribute to the existing body of knowledge on management and leadership and with this, provide additional insight into the importance of wellbeing within the two banks. The concepts of motivation and supervisory behaviours were explored in relation to different styles of leadership while the importance of employee wellbeing was further investigated in relation to performance. The study was conducted and analysed using quantitative data that was collected through an online questionnaire. The sample size included 144 employees from two Retail Banks. Most of the sample included back-office managers, professional bankers and analysts which included 50% from Retail Bank A, and the other 50% were from Retail Bank B, both in Sandton, Johannesburg. The study found that democratic and transformational leadership styles were most effective at increasing employee motivation and employee performance. These two forms of leadership styles have a positive influence on productivity, job satisfaction, and overall employee performance. It was also found that the autocratic leadership style had negatively affected supervisory behaviour. Autocratic leadership style demotivated employees causing higher levels of job dissatisfaction. Relationships between supervisory behaviour and employee wellbeing together with employee performance were also identified.Item Perceived barriers to digitalization by small-scale farmers Gauteng Province(University of the Witwatersrand, Johannesburg, 2022) Choguya, DonaldDigitalization in the fourth industrial revolution era has transformed many industries across the board. However, there are some that have been affected more than the others as depicted in the digital vortex. Lagging is the agricultural sector. This study was a quantitative research study that utilized a sample of 40 small-scale farmers to be representative of the Gauteng Province small-scale farmers. The research related the perceived barriers to digitalization and its impact to the agricultural activities of small-scale farmers in Gauteng Province. The data was analysed using the multiple regression analysis and correlation coefficient. Analysis of the results showed a massive gap between small-scale farmers and commercial farmers on the adoption of digitalization. Further analysis indicated that small-scale farmers were less likely to be impacted by digitalization to adopt technological utilization. It was also found that small-scale farmers were contributors to food production. Finally, it was also discovered that small-scale farmers were less established to adapt and adopt to digitalization in their agricultural activities due to various barriers. The recommendations were that there was need to do more research to find ways to bridge the gap to digitalization between small-scale farmers in Gauteng Province and commercial farmers. So that small-scale farmers in Gauteng Province especially the small-scale farmers in rural areas could also be exposed to the digitalization of operations to enable them to improve productionItem From Fatherlessness to fatherhood: Experiences of adult Black South African men in the Gauteng Province.(University of the Witwatersrand, Johannesburg, 2022) Senwamadi, Jacob Ramasoane Makgoane John; Matee, HopolangThis study aimed to explore the experiences of Black South African first-time fathers who grew up without their biological fathers, as well as how these men perceive their fathers’ absence to have influenced their experiences of fatherhood. Individual semi-structured interviews were conducted with five Black first-time fathers between the ages of 25-30. The study followed a qualitative explorative design where the participants were recruited using purposive sampling. The findings of the study revealed that some of the first-time fathers had known their biological fathers’ identities during childhood even though they were not physically or financially present in their lives. Furthermore, they did not form any close relationship with them. The participants reported to have experienced rejection from their fathers while growing up. There was a common thread amongst the participants with regards to the need to feel accepted by their biological fathers. This appeared to be a powerful motivational basis for the men’s’ interpersonal experiences. The experience of rejection in childhood has been found to have many negative effects on an individual’s development later in life. This includes increased aggression, increased internalising of difficulties in adolescence, and psychopathological symptoms in adulthood. It has also been found that individuals with this experience are more likely to hold distorted mental representations that could lead to perceiving rejection and hostility in interpersonal relationships, and to further interpret relationships as being untrustworthy and unpredictable. What the participants experienced in this study is consistent with what has been reported in psychoanalytic literature; fatherhood is defined in connection to the father's function in the Oedipus complex where his function as an intrapsychic construct, also known as the "internal father," and their involvement in child development. It was concluded that in post-apartheid South Africa, numerous factors such as high levels of unemployment, poverty, and inequality are amongst the major determinants of family disruptions particularly among the Black people. The situation is exacerbated by the burden of HIV/AIDS and violence-related mortality. The family and parental practices have been significantly affected leaving so many children growing up without biological fathers, either through rejection or premature death.Item Innovative Financing Models for Rural Electrification in the Eastern Cape, South Africa(University of the Witwatersrand, Johannesburg, 2022) Maphosa, Thobile; Soumonni, OgundiranThis research report is based on a case study that examines innovative financing models for rural electrification in the Eastern Cape, South Africa.
