Physical sciences teachers' experiences of online teaching during the COVID-19 Pandemic
No full textText in EnglishThe inspiration for this study came from the researcher's own learning experiences during the COVID-19 pandemic. This researcher's experience made them consider how practical learning is essential for scientific learners. The purpose of the research was to determine how physical science subjects are taught and learned in high schools in the Amajuba District of KwaZulu-Natal. To explore the phenomenon, a mixed-method approach was employed which combined qualitative and quantitative approaches. Educators who were involved in teaching physical sciences were the target demographic for this study. There were three stages to the data gathering. In the first stage, the quantitative data were collected from 120 teachers through a structured closed-ended questionnaire. In the second stage, qualitative data were collected from 10 physical sciences teachers through in-depth interviews. For the qualitative approach, the interview guide and open-ended questions were used, and a face-to-face in-depth interview was conductePh. D. (Natural Sciences)College of Educatio

Ubuntu and asset building: decolonising and practicalising cattle ownership in rural South Africa
Get PDFThis is a qualitative paper built on literature review. Some literature allege that subsistence communal cattle farmers were unwilling to participate in mainstream marketing as a matter of choice, alternatively lack of capital and skills. My doctoral thesis similarly found but one factor stood out to the contrary. It found that the majority of the participants instead kept animals for other people without owning such animals. This impacted on lack of decision regarding market participation. Various strategies and policy tools have been adopted in most African communities to empower poor individuals to own cattle, but these strategies have achieved mixed results. My lecture here this evening extracted lack of ownership as needing attention to redress the problem. This lecture builds on the assertion that African indigenous instruments and tools can address the problem. This paper adopted the Girinka approach which was used in Rwanda to transfer cattle to empower poor households to own cattle as the framework. This Girinka produced good results and empowered many households on cattle ownership. Poor households managed to build asset base which enabled them to build wealth. This lecture uses Ubuntu as an instrument which could be used to transfer cattle from the fortunate to the less fortunate households to empower the poor to own cattle and build sustainable wealth.Development Studie
Knowledge management systems implementation in selected mobile telecommunication companies in Namibia
No full textOrganisational knowledge management systems (KMS) garner global attention in
organisational environments for organisational knowledge management (KM)
practices. Organisations are grappling with the best ways to manage organisational
knowledge (OK) to foster innovation and increase organisational competitiveness.
Organisational KMS enable critical processes such as knowledge acquisition,
creation, transfer, sharing, dissemination, classification, identification, and capture
within an organisation to foster continuous innovation for competitive advantage.
Mobile telecommunication (MT) companies in Namibia must therefore recognise that
the success of their organisational KMS implementation contributes significantly to
organisational KM practices that can enhance employee and organisational
performance.
The study explored the current state of organisational KMS implementation in selected
MT companies in Namibia. The study used the technology organisation environment
(TOE) and the socialisation externalisation contribution and internalisation (SECI)
theories to aid in conceptualising the framework of the study. The study used a mixed method approach via a convergent parallel design.
The sample of the study was made up of 329 employees from two selected MT
companies in Namibia. Twenty interviews and document analysis were employed in
the qualitative method. On the other hand, the survey was conducted under a
quantitative method. Purposive sampling was used to select qualitative participants
and documents. Three hundred and nine respondents for the quantitative phase were
identified using proportionate simple random selection under probability sampling, and
the response rate was 57%. The Statistical Package for the Social Sciences (SPSS)
22.0 was utilised to analyse quantitative data and generate descriptive statistics in the
form of tables and graphs. ATLAS.ti 22 was utilised to extract, categorize, and link
data segments from interviews with eleven participants and documents to discover
patterns and themes.

Exploring the perceptions of managers concerning the trainee audit programme as an employment equity tool at the Auditor General of South Africa
No full textIncludes summaries in Afrikaans and Northern SothoSuid-Afrika is 'n land met baie wette, en een daarvan is die Wet op Gelyke Indiensneming (EEA), No. 55 van 1998. Die EEA het in 1998 in werking getree met die doelwitte om gelyke geleenthede en billike behandeling in indiensnemingspraktyke te bevorder. In reaksie op die vereiste van die EEA het die ouditeur-generaal van Suid-Afrika (OGSA) se EE-beleid ten doel om konsekwentheid onder werknemers te verseker wanneer EE in die werkplek geïmplementeer word. Ten spyte van die EE-beleid wat bestaan en gereeld hersien word, en 'n spesifieke opleiding- en ontwikkelingsprogram vir leerlingouditeure (TA) wat ontwerp is om die poel opgeleide werknemers uit alle aangewese groepe te vergroot, slaag die OGSA steeds nie daarin om hul teikens te bereik soos uiteengesit in hul EE-plan nie. Die studie was bedoel om die volgende vraag te beantwoord: wat is die ouditeur-generaal van Suid-Afrika bestuurders se persepsies oor die leerling oudit (TA)-program as deel van hul gelyke indiensneming (EE) implementeringsplan van aksie?
Kwalitatiewe navorsing is toegepas. Dertien deelnemers is met behulp van doelgerigte steekproefneming geïdentifiseer. Semi-gestruktureerde onderhoude is gebruik om data in te samel. As deel van die inhoudsanalise is die getranskribeerde onderhoude met behulp van ATLAS.ti ontleed.
Die resultate het aan die lig gebring dat sommige deelnemers nie saamgestem het dat die TA-program 'n komponent van EE is nie. Soveel as wat die resultate getoon het dat die meeste deelnemers die TA-program as 'n pyplyn gesien het wat bestuur kan gebruik om vakatures te vul, is EE volgens die deelnemers nie oorweeg tydens die werwing van die leerling ouditeure nie.
Die studie is beperk deur die feit dat dit slegs op hierdie organisasie gesentreer is, en geen ander organisasie in Suid-Afrika vervul dieselfde mandaat as die AGSA in die openbare sektor nie.South Africa is a country with many laws, and one of them is the Employment Equity Act (EEA), No. 55 of 1998. The EEA came into effect in 1998 with the objective to promote equal opportunities and fair treatment in employment. In response to the requirement of the EEA the Auditor General of South Africa (AGSA’s) EE policy aims to ensure consistency among employees when implementing EE in the workplace. However, despite the EE policy that exists and is frequently reviewed, and a specific Trainee Auditors (TA) training and development programme designed to increase the pool of trained employees from all designated groups, the AGSA still fails to achieve their targets as set out in their EE plan. The study intended to answer the following question: what are Auditor General of South Africa (AGSA) managers' perceptions about the trainee audit (TA) programme as part of their employment equity (EE) implementation plan of action?
Qualitative research was applied. Thirteen participants were identified using a purposive sampling strategy. Semi-structured interviews were used to collect data. As part of the content analysis, the transcribed interviews were analysed using ATLAS.ti.
The findings revealed that some participants disagreed that the TA programme is a component of EE. As much as the findings showed that most participants saw the TA programme as a pipeline that management could use to fill vacancies, EE, according to the participants, was not considered during the recruitment of trainee auditors.
The study was limited by the fact that it is only centred on this organisation, and no other organisation in South Africa fulfils the same mandate as the AGSA in the public sector.Afrika Borwa ke naga yeo e nago le melao e mentši, gomme e nngwe ya yona ke Molao wa Tekatekano ya Mešomo (EEA), No. 55 wa 1998.

Economic sectors and globalization channels to gender economic inclusion in Sub-Saharan Africa
No full textThis study complements the extant literature by assessing economic sector and globalization channels for gender economic inclusion. The study is focused on 35 countries in sub-Saharan Africa for the period 1995-2019 and the empirical evidence is based on fixed effects regressions. The following findings are established. First, economic and political globalization positively affect female employment in agriculture and the positive effect of economic globalization is driven by the trade globalization dynamic while social globalization negatively affects female employment in agriculture and the negative effect of social globalization is driven by cultural and informational globalization dynamics. Second, aggregate globalization and sub-components (i.e. economic globalization, social globalization and political globalization) negatively affect gender employment in the industry and the negative effect is driven by the financial globalization sub-component of economic globalization and by the informational and cultural components of social globalization. Third, aggregate globalization and sub-components positively affect gender employment in the service sector and the corresponding positive effect is driven by the trade globalization sub-component of economic globalization and by all sub-components (i.e. interpersonal, informational and cultural dimensions) of social globalization. In the terms of policy implications, policy makers should focus on promoting dimensions of globalization that are established to positively influence female employment as well as put in place measures that are designed to reverse the negative incidence of globalization dynamics that have been established to affect female employment. Moreover, policy makers should also be aware of the fact that when formulating the corresponding policies, the effect of globalization is contingent on globalization dynamics as well as on various economic sectors.Economic
Selected clan praises as importers of heritage: a case of Ema Swati of eSwatini
No full textClan praises are of paramount importance in Eswatini. This research examined selected EmaSwati clan praises to establish if clan praises are importers of heritage to the present generation. Underpinned by the diffusionist and functionalism theories, the study was qualitative, with research conducted among twenty (25) EmaSwati clan names belonging to the four groups of clans namely: Bemdzabuko, Emakhandzambili, Ematalankhosi, and Emafikamuva. A systematic sample of fifty (50) participants was drawn, and semi-structured interviews were used to gather data. After a descriptive content analysis of data, it was revealed that clan praises are importers of heritage to the present generation and confirmed that clan praises are esteemed among EmaSwati of Eswatini, but the youth have limited knowledge of them. In light of these findings, the study recommended that the government incorporates clan praises into the curriculum, initiate writing competitions, and campaigns on clan praises.M.A. (African Languages)African Language
Cyclical Longitudinal Ethnography as an Innovative Design for Addressing Sexuality Education in South African Rural Farm Schools
No full textAddressing Sexuality Education among learners in rural schools can be challenging when using traditional designs such as ethnography
and phenomenology. This paper introduces Cyclical Longitudinal Ethnography as an innovative design for addressing Sexuality
Education in South African rural farm schools. This design was developed as part of an engaged scholarship on HIV prevention in rural
farm schools in Soutpansberg North Circuit, Limpopo Province, South Africa. The paper provides an overview of Sexuality Education
at schools and the challenges thereof. It further provides the basics of ethnography and its limitation. The paper then introduces and
describes cyclical ethnography as an alternative to original ethnography. The design allows researchers to still have a prolonged
engagement with the community without gross disruption of other academic responsibilities such as tuition, academic citizenship,
leadership, and administration. The design allows the researcher to visit the area several times over the years, enabling the researcher
to observe variations of a phenomenon over time. The Cyclical nature of the design allows data collection, analysis, intervention,
monitoring, and evaluation to be conducted iteratively. Though there are primary key informants, the findings could lead to other key
informants, settings, and interventions which were not part of the initial plan and objectives. In this study, the target population was
educators teaching Sexuality Education, but it ended up involving learners, parents, and community members. The Longitudinal nature
of the design enables the researchers to see the impact of the interventionsCollege of Human SciencesMedical Research Council of South Africa

Factors associated with stunting in children 0-59 months in the Manzini region in eSwatini
Get PDFText in EnglishThis study aimed to identify and describe factors associated with stunting in children the Manzini region so that evidence-based recommendations could be made to relevant policymakers. A quantitative, cross-sectional study design was employed. Convenience sampling was done at two child welfare clinics, and data was collected from 338 mother-child pairs using a questionnaire and a checklist for anthropometric measurements. On multivariate analysis, statistically significant factors associated with stunting were children with an age gap of less than two years their older sibling [OR = 2.47, p = 0.05] , a birthweight of less than 2500g [AOR = 4.00, p = 0.005]. Drinking treated water [AOR = 0.36, p = 0.01] had a statistically significant protective effect. Therefore, to reduce stunting and its consequences, policymakers must improve nutritional support for children born with low birth weight, maternal access to family planning, and the provision of clean, safe water to Manzini residents.M.A. (Public Health)Health Studie
The effect of value-added tax on economic growth in South Africa
Get PDFIncludes summaries in Sesotho and AfrikaansThe study investigated the effect of value-added tax on economic growth in South Africa using the Autoregressive Distributed Lag (ARDL) bounds tests approach for cointegration for the period 1991 to 2020. The results of the study showed that there was a long-run relationship between the variables when investment was used as the dependent variable. The results of the ECM showed that GDP growth had a significant and positive effect on investment, while VAT had a positive but non-significant effect on investment. The causality test results showed that GDP Granger-cause investment, and that a bi-directional causal relationship existed between VAT and investment. These results therefore prove that growth could be achieved in South Africa when government allocates the revenue raised through a well-designed value-added tax to productive expenditure, such as human capital, research and development and investing in infrastructure. In other words, the findings of the study confirms that VAT has the potential to impact economic growth when the increased revenue is allocated towards well-targeted investment. To mitigate the adverse effect of a VAT increase on the disadvantaged, this could be addressed by diverting the revenue back to the poor through increased spending on housing and health to reduce poverty and inequality.Patlisiso e batlisitse sephetho sa lekgetho la boleng bo ekeditsweng ho kgolo ya moruo Afrika Borwa ka ho sebedisa mokgwa wa diteko tsa mellwane tsa Autoregressive Distributed Lag (ARDL) bakeng sa kopanyo bakeng sa nako ya 1991 ho isa ho 2020.

Die resultate van die studie het getoon dat daar 'n langtermyn was verband tussen die veranderlikes wanneer belegging as die afhanklike veranderlike gebruik is. Die resultate van die ECM het getoon dat ekonomiese groei 'n beduidende en positiewe uitwerking op investering gehad het, terwyl belasting op toegevoegde waarde 'n positiewe maar nie-beduidende uitwerking op investering gehad het. Die oorsaaklikheidstoetsresultate het getoon dat ekonomiese groei Granger investering veroorsaak, en dat 'n tweerigting-oorsaaklike verband tussen belasting op toegevoegde waarde en investering bestaan het. Hierdie resultate bewys dus dat groei in Suid-Afrika behaal kan word wanneer die regering die inkomste wat verkry word deur 'n goed ontwerpte belasting op toegevoegde waarde toewys aan produktiewe uitgawes, soos menslike kapitaal, navorsing en ontwikkeling en investering in infrastruktuur. Met ander woorde, die bevindinge van die studie bevestig dat belasting op toegevoegde waarde die potensiaal het om ekonomiese groei te beïnvloed wanneer die verhoogde inkomste aan goedgerigte belegging toegewys word. Om die nadelige uitwerking van 'n belasting op toegevoegde waarde verhoging op die benadeeldes te versag, kan dit aangespreek word deur die inkomste na die armes terug te lei deur verhoogde besteding aan behuising en gesondheid om armoede en ongelykheid te verminder.M.
