Item Caregiver's oral health knowledge, attitudes and practices towards children with special health care needs in Harare Province, Zimbabwe(University of the Witwatersrand, Johannesburg, 2023-11) Mashanda, Vimbai; Tootla, Saidah; Malauy, CathrineBackground: Children with Special Health Care Needs (CSHCN) are prone to oral diseases such as dental caries and periodontal disease. This is due to limitations in oral hygiene practices because of their debilitating conditions. Therefore, caregivers play a major role in the maintenance of CSHCN’s oral health. As a result, caregiver’s oral health knowledge and attitudes are important to ensure that the oral health of CSHCN is maintained. Aim and Objectives: The aim of this study was to describe the caregiver’s oral health knowledge, attitudes, and practices (KAP) towards CSHCN. The objectives of the study were to determine the caregiver’s demographic profile, to assess the caregiver’s oral health KAP towards CSHCN and to assess whether there is a relationship between the caregiver’s level of education, demographic characteristics, and oral health KAP and factors related to oral health practices. Methods: A quantitative cross-sectional study design and convenience sampling method was utilised. Caregivers above 18 years of CSHCN who attended support group meetings in Harare Province, Zimbabwe and were willing to participate, took part in the study. A modified self-administered questionnaire (SAQ) was used for data collection. The SAQ comprised of a demographics section for the caregiver, child’s disability type and oral health KAP questions. Two sample t-tests and Analysis of Variance (ANOVA) was used to compare the means of caregivers KAP. Multiple linear regression model was used to assess the association between caregivers’ KAP and demographic characteristics. Only the variables with p<0.15 in the univariate model were included in the multiple linear and multivariate logistic regression models. Multivariable logistic regression was used to assess the association between caregivers’ oral health practice and demographic characteristics. Apriori variables such as age, level of education, knowledge and attitude were selected for all multivariable logistic models. All variables with p<0.05 were considered to be statistically significant and statistical analysis were performed using Stata. Results: The response rate was 76.8% n=295). Almost 90% (89.2%, n=263) of the caregivers were females and nearly three quarters (72.5%, n=214) were mothers. A third (33.6%, n=99) of the caregivers were aged between 31-40 years. Fifty-three percent (n=157) of the caregivers were unemployed and 61.7% (n=182) were educated up to high school level. Forty-six percent (n=135) of the CSHCN had cerebral palsy. Out of the 295 caregivers, 45.4% (n=134) had fair oral health knowledge, 79.7% (n=235) had a good attitude towards oral health and 62% (n=183) had fair oral health practices. Conclusions: Most of the caregivers had good oral health attitude, however their knowledge and practices were fair. Factors associated with caregivers’ attitude were their knowledge and level of education, and the caregivers’ practices were associated with knowledge and attitude.Item Knowledge, attitudes and practices of clinician management of adults presenting with acetylcholinesterase inhibitor poisoning(University of the Witwatersrand, Johannesburg, 2024) Redant, Dean PatrickBackground: Acetylcholinesterase inhibitor (AChE-I) poisoning is a common cause of deliberate self-harm in South Africa (SA). Whilst there is existing literature on the epidemiology and management of AChE-I poisoning, there is a lack of research on the South African clinician’s knowledge, attitudes and clinical practice when managing these patients. Objectives: To describe the knowledge, attitudes and practices (KAP) of clinicians when managing adult patients with AChE-I poisoning in academic emergency departments (ED) in Southern Johannesburg, Gauteng. To describe the correlation between the clinician’s demographics and experience to their knowledge, attitudes and practices in this setting. Methods: One hundred and forty-five clinicians completed a structured questionnaire used to gather data on clinicians’ knowledge, attitudes and practices (KAP) with regards to their management of patients with AChE-I poisoning. Descriptive and inferential statistics were used to analyse the data and to infer correlation between clinician’s KAP vs clinician’s demographics and experience. Results: One hundred and forty-five questionnaires from 5 EDs were completed and analysed. Of which 86 (59%) of participants were female and 59 (41%) were male. The majority of participants were under the age of 40 (84%) and employed as Grade 1 Medical Officers (39%). Years of experience were divided into <2 years, 2 – 5 years and ≥5 years with each group representing a third of the sampled population. Clinician average knowledge scores on AChE-I poisoning were good (77.9% n= 12.46/16) with scores improving predictably with years of experience (72.5% in <2 years to 83% in ≥5 years). Attitudes towards managing patients with AChE-I poisoning were overall neutral. Clinician practices varied greatly, particularly with adjustment of atropine infusions and adjunctive treatments used. Conclusion: Clinicians had an overall good knowledge of AChE-I poisoning which improved predictably with greater experience managing these patients. Practices were highly varied across all demographic groups despite access to protocols in most departments studied. Attitudes were generally neutral with no clear impacting factors. Clinicians agreed unequivocally that the public health system did not provide sufficient primary preventative care in order to address the underlying factors driving patients to self-harm. This research revealed that the medical and psychosocial management of adult patients with AChE-I poisoning can be improved upon through specific clinician training.Item The Adaptation of the Shadow Corpse Belief System for Change Management in Corporate Organisations(University of the Witwatersrand, Johannesburg, 2021) Chazuza, Richard G.; Maier, ChristophThis thesis examines how the use of an African natural idea and practice, Mumvuri loosely translated in English to the Shadow on the Corpse Belief System can be adapted and used to understand change management in corporate organisations. While the talk of Ubuntu and other African ideas has received a lot of prominence in organisations and academia of its potentially untapped value in management, few to non-existent African ideas and practices are known to realistically permeate and guide management thinking and practices in corporate organisations. This thesis is informed and guided by the interpretive paradigm. It adopted and followed the qualitative approach where the basic interpretive qualitative research design was used. In-depth, semi-structured, open ended and thematised interviews were used to collect data from 35 carefully selected experts that were placed into 3 homogeneous groups. Thematic analysis was used as the data analysis method aided by ATLAS ti version 8 software package, a computer assisted data analysis software package (CAQDAS). The evidence from the research revealed that Mumvuri is a known and commonly practised African socio-cultural belief system. Even though it is rooted in the Karanga ethnic culture of modern day Zimbabwe, its traces are found in other African cultures. Despite the prevalence of Mumvuri in African culture, it has not been adapted and used in corporate organisations. The main contribution was the development of a conceptual framework for change management in corporate organisations and the accompanying guidelines of implementation for executives and practitioners. These guidelines outline the process of adaptation of Mumvuri as an African idea, belief and concept in management. The thesis makes an empirical, methodological and practical contribution. Further research is suggested in testing this conceptual framework in corporate organisations.Item Examining the technologies and practices that can help SA mining industries meet carbon blueprint reductions(University of the Witwatersrand, Johannesburg, 2023) Lakhna, Adheesh; Oro, Ufuo OroMining has always been regarded as a black sheep due to its legacies of environmental accidents, pollution, and safety incidents. However, for economies to grow, they need energy and energy requires metals to generate, transmit and store power. These metals are mostly sourced from mining and so as the world changes to cleaner and greener energy options, it is only fitting that mining equipment also becomes more environmentally friendly and keep up with the times. Heavy mining equipment such as ultra class dumptrucks and face shovels have 2-3MW diesel engines which can easily burn hundreds of litres of diesel per hour (Komatsu, 2022). Diesel has been the fuel of choice for many years due to its developed supply chains, ease of storage, high energy density and reliable engines. High fuel consumptions coupled with increasing fuel prices and deepening mines means that in addition to increasing expenses and pressure from environmental organisations, South African mines are becoming more and more carbon intensive. In December of 2015, at the 21st Conference of the Parties (COP21) to the United Nations Framework Convention on Climate Change (UNFCCC) held in Paris, an international treaty on climate change was adopted by 195 parties. This treaty also known as the Paris agreement was a landmark agreement since this was the first legally binding treaty aimed at fighting climate change (United Nations Climate Change, 2015). The Paris agreement covered many items but these are some of the most crucial ones; Long-term temperature goals with the aim of restricting global temperature increases to below 2 degrees Celsius or even further to 1.5 degrees Celsius; National Adaptation Plans which outlines plans and actions for different nations based on their needs and priorities; Finance, technology and capacity-building support that addresses developed countries providing financial assistance to less endowed countries for adaption and accelerating technology developmentItem The perception of the impact of the Fourth Industrial Revolution on the production in South African mines(University of the Witwatersrand, Johannesburg, 2022) Ledwaba, SolomonThe aim of the study was to explore the perception of Fourth Industrial Revolution(4IR) strategies and practices in relation to production process performance in the mining industries at selected mines in South Africa. The study followed a quantitative research methodology, and a sample of 110 employees at the selected mines in South Africa, consisting of 60 mine workers, 10 information technology employees, 10 middle managers, 10 operations managers, 10 health and safety personnel, and 10 executive officers were drawn using a simple random sampling approach. Primary data was collected using a questionnaire with a 5-point Likert Scale. Data were analysed using the SPSS version 4.1. Findings from the study reveal that employee level of awareness of the concept of 4IR and associated technologies had a significant impact on how employees perceived the current 4IR strategies. Though findings show that a high percentage of employees were involved in the 4IR strategy development process, most believe that the current 4IR strategies and practices did not fully represent the interests of all stakeholders. While some were of the perception that the strategies and practices were designed to improve productivity and reduce employment costs, others believe that it puts workers’ jobs at risk, as mines had started replacing humans with 4IR technologies such as robots and drones. However, findings reveal that the adoption of the 4IR technologies according to the perception of employees, has improved health and safety within the mines
