The identities and practices of faculty managers in a higher education institution in South Africa

Magister Commercii - MComThis study addressed the identities and practices of faculty managers (FM) in a higher education institution (HEI) in South Africa. There is limited research on faculty managers in South African HEIs, specifically in relation to their self-formed ethically related identities and practices. My aim in this study was to fill this gap. Ethics as self-formation is related to how people construct themselves. As a result of changes in the managerial discourse in HEIs in South Africa, the new social identity of the faculty manager, which is a non-teaching professional social identity, has been created. At the same time, individuals have ethical aspirations that they bring with them when they occupy new management positions. These ethical values and aspirations influence how these individuals enact and fashion their identities at work. The major goal of this study was to explore how individuals who are faculty managers construct their ethically infused identities and enact their practices. In analysing the empirical evidence I used a Foucauldian ‘ethics of the self’ theoretical lens. In setting up and gathering the data for this study, I used the case study qualitative research approach in order to gain a contextual and deep understanding. The findings of this study show the various shapes and shades of ethically infused subjectivities that people who occupy the positions of faculty managers enact and instantiate. In addition, the study sheds light on the roles and responsibilities of faculty managers and shows the major contribution they make to the management and administration of higher education institutions

South African and non-South African residents in Cape Town: Awareness level, purchase intention and buying behaviour towards purchasing halal food products

Philosophiae Doctor - PhDMuslims and non-Muslim consumers regardless of who they are or from where they come, whether natives or foreigners in a particular country are much concerned with consuming food products. However, not any researchers in South Africa (SA) have addressed the consumers who buy food products labelled halal. This doctoral dissertation primarily aims to explore and bring new knowledge towards halal food purchasing behaviour. It specifically focuses on understanding the current purchase intention and behaviour of halal consumers in Cape Town, South Africa. For this purpose, the Theory of Planned Behavior (TPB) was utilised as the theoretical framework to measure the purchase intention and subsequently the buying behaviour of halal consumers. An exploratory sequential mixed method was adopted. A qualitative approach formed the first phase of the study, while a quantitative approach formed the second phase of the study. For the qualitative phase, data was collected purposively through 9 intensive semi-structured interviews. Nonetheless, for the quantitative phase, data was collected by means of 516 self-administrated questionnaires using a stratified random sampling. In analysing the qualitative data, thematic analysis was applied. However, for the quantitative phase, data was analysed using multivariate statistical analysis known as the Structured Equation Modelling (SEM)

Myasthenia Gravis Exacerbation Following COVID-19 Vaccine: A Case Report

Background: As of December 2021, the World Health Organization (WHO) reports that Coronavirus disease 2019 (COVID-19) led to about 5,403,662 deaths. While COVID-19 has resulted in millions of deaths worldwide to date, vaccination remains the mainstay of infection control. AZD1222 (AstraZeneca vaccine) was distributed in Sudan by the COVID-19 Vaccines Global Access facility in March 2021. It was added to the emergency use list by WHO in the middle of February 2021. However, vaccine safety among patients with autoimmune diseases, such as myasthenia gravis (MG), is yet to be established. MG is a relatively rare illness that could result in life-threatening complications. Myasthenic crisis is considered the most serious complication of MG that can lead to death due to aspiration and respiratory failure. Plasma exchange (PLEX), Immunoadsorption (IA), and intravenous Immunoglobulin (IVIG) are the first-line treatment for myasthenic crisis. It is proven that cortisone has a positive effect when used as add-on therapy with PLEX/IA and IVIG.   The case: We report the case of a 37-year-old Sudanese female who presented to the emergency room with an exacerbation of her previously well-controlled MG following her second dose of AZD1222 vaccination. The exacerbation symptoms at time of presentation were severe generalized body weakness that increasing overtime and shortness of breath. Computerized tomography of the chest was performed, and it revealed no evidence of COVID-19. Management at the ER started with rehydration and IV methylprednisolone 1g, followed by IV hydrocortisone 200mg. She continued to deteriorate and was admitted to the intensive care unit where she was intubated and placed on a mechanical ventilator. IVIG was requested but couldn't be obtained due to the low-income setting, and fourteen days after admission patient died due to circulatory collapse. Our study aims to present an MG case with features of MG exacerbation following the administration of the second dose of AZD1222.   Conclusion: Little is known about the effect of different COVID-19 vaccines on subgroups of patients with autoimmune diseases like MG. Although the safety profile of AZD1222 is generally reassuring, people with severe underlying diseases were excluded from trials. Therefore, more efforts and experimental studies may be needed, with closer vigilance in MG patients. It has not been elucidated how the COVID-19 vaccine might provoke autoimmunity, but several theories have been proposed. Molecular mimicry theory can explain how the genetic material of a virus could provoke autoimmunity, it describes the cross-reactivity of antibodies produced against proteins that are encoded by viral genetic material with the proteins located at the post-synaptic membrane. There is a debate about whether vaccine benefit outweighs the risk in MG patients or not. However, we believed that MG patients should be informed about the benefit and risks of COVID-19 vaccination. &nbsp

Review an assessment of electromagnetic wave propagation in sand and dust storms at microwave and millimeter wave band - part II

Suspended particles in the atmosphere during sand and dust storms have numerous consequences on electromagnetic wave propagation in arid regions. The electromagnetic wave signal may suffer attenuation and cross polarization upon encounter with the suspended particles. However, meager information has hitherto been reported about effect of storms on the telecommunication systems operating in such regions. This paper presents a survey of current understanding of the electromagnetic wave propagation in sand and dust storms. A review of the literature covering electromagnetic scattering theory and applications is given. The review describes the principle of approach and technology adopted for the investigation highlighting both strengths and drawbacks. Detailed parametric assessment of the effects of storms on wave propagation as it concerns signal attenuation and cross polarization is also carried out. The results demonstrate that most authors have calculated the attenuation effect, revealing that it is not very significant unless very high suspended dust densities are assumed (i.e., during severe sand and dust storms). A few papers indicate the possibility of more significant cross polarisation. The obvious gap in knowledge of this field is finally also clearly established

Factors affecting consumers’ intention towards purchasing halal food in South Africa: a structural equation modelling

This research study highlighted the factors that influence the intention of consumers to buy halal food products. In this study, the researchers have chosen to address the gap in the literature pertaining to non-South African consumers’ purchase intention. Non-South Africans are foreign people who reside in South Africa including immigrants, workers, and students. Through utilising the theory of planned behaviour, this study aims to determine the attitudes, subjective norms, perceived behaviour control, and awareness of non-South African towards purchasing halal food products. This also attempts to identify the strongest factor that influences the purchasing intention of halal food by non-South African consumers. The sample of the study consisted of 230 non- South African consumers in Cape Town. Data were collected through self-administered questionnaires. Structural equation modelling (SEM) was used to identify the structural relationships among the constructs identified and to test the study hypotheses. The findings of this study indicate that there is a significant relationship between awareness and buying behaviour. Interestingly it found that only the attitude dimension of TPB had a significant relationship with purchase intention, whereas subjective norms and perceived behavioural control did not show a significant relationship with the consumer intention variable

Myasthenia Gravis Exacerbation Following COVID-19 Vaccine: A Case Report

Background: Vaccination remains the mainstay of strategy for prevention of Coronavirus Disease-2019 (COVID-19). AZD1222 (AstraZeneca vaccine) was distributed in Sudan by the COVID-19 Vaccines Global Access facility in March 2021. It was added to the emergency use list by the WHO in mid-February 2021. However, vaccine safety among patients with autoimmune diseases, such as myasthenia gravis (MG), is yet to be established. MG is a relatively rare illness that could result in life-threatening complications. Myasthenic crisis is considered the most serious complication of MG that can lead to death due to aspiration and respiratory failure. The case: We report the case of a 37-year-old Sudanese female who presented to the emergency room with an exacerbation of her normally well-controlled MG following her second dose of AZD1222 vaccination. She continued to deteriorate and was admitted to the intensive care unit, where she was intubated and placed on a mechanical ventilator. The low-income setting was a major barrier in obtaining intravenous immunoglobulin until the patient died. Our study aims to present an MG case with features of MG exacerbation following administration of a second dose of AZD1222. Conclusion: Little is known about the effect of different COVID-19 vaccines on subgroups of patients with autoimmune diseases like MG. In our case, an exacerbation of MG may have been precipitated by the COVID-19 AstraZeneca vaccine. Therefore, more efforts and experimental studies may be needed, with closer vigilance in MG patient
