- Description: The achievement of the right to education for all children in Namibia is fundamentally dependent upon the quality of education provided to these learners irrespective of their social circumstances. Being a sparsely populated region, nearly half of the primary schools in the Kavango West region have fewer than 100 learners; thus, these small schools are regarded as not economically viable. The educational development in rural regions is shaped by limited access to quality, inclusive education and the persistence of low-quality primary education which has resulted in high repetition rates and dropouts. This research is a Critical Discourse Analysis of the education policies and regulations. As a case study, it unpacks Formal Education Circulars on staffing norms and on the closure of small schools, looking at their affordances/constraints on the provision of inclusive quality education for children schooling at small schools in Namibia. Interviews and document analysis were used to gather data. Critical Theory frames the process of ideological critique which, among other things, identifies inequalities and factors that limit human freedom and how such factors can be alleviated. The research asks the question: what are the explicit and implicit underlying realities experienced at one-man schools, which depict the varied situations in which these schools survive? Factors emerging from the study showed that small schools in Namibia are symbols of inequity and the exclusion of educationally marginalised children and their poor communities. Small schools are hardly able to sustain and draw in the resources required to meet the education needs of marginalised communities which fall under the multidimensional poverty index in Namibia. The study found that at the moment there are no deliberate efforts from the Ministry of Education to bring about the necessary changes to small schools, and therefore one-man schools have continued to operate as isolated sections of an inflexible system. It is my contention that deliberate efforts are still needed to improve small schools. Policy decisions that respond to the current challenges faced by one-man schools may be sufficient to bring about noteworthy changes in the operations of one-man schools and these changes could effectively impact the learners learning. The decision to drive change requires a multilayered approach that articulates a clear vision, which is systematically implemented to improve one-man schools in Namibia. , Thesis (MEd) -- Faculty of Education, Primary and Early Chilhood Education, 2023

- Description: To investigate the potential anti-diabetic/obesity properties of oral cannabis administration in an obese and streptozotocin (STZ)-induced diabetic rat model, as well as an obese rat model, and to determine the mechanism of action, with a focus on the peritoneal and intramuscular fat depots. Experimental Design: Obese and STZ-induced diabetic rats were allocated a high fat diet (HFD) and intraperitoneally injected with STZ to mimic an obese and diabetic state. The rats were then orally administered cannabis extract (CE) of 1.25, 2.5 and 5.0 mg/kg body weight (relative to tetrahydrocannabinol (THC) content) or metformin as a positive control. For the obese rat model, the rats were allocated either a high carbohydrate diet (HCD) or high fat diet (HFD) and orally administered with cannabis extract of 1.25 mg/kg body weight (relative to THC content). Weight, blood and insulin-resistant parameters of the rats were monitored. The mitochondrial to genomic DNA ratio (MT:18S DNA), average adipocyte area of the various adipose tissues, citrate synthase and carnitine palmitoyltransferase 1 (CPT1) enzyme activities of the peritoneal and intramuscular fat were measured. Gene expression levels of uncoupling protein 1 (UCP1), cell-death inducing DNA fragmentation factor alpha like effector-a (Cidea), perilipin, hormone-sensitive lipase (HSL) and mitochondrial transcription factor A (TFAM) were measured in peritoneal fat, intramuscular fat and brown adipose tissue (BAT). Main Findings: Obese and STZ-induced diabetic rat model: Due to the biphasic nature of cannabinoids, cannabis dosage plays an important role in the observed effects. CE1.25 was the only cannabis treatment effective in improving the insulinresistant parameters of the rats unlike the other higher cannabis concentrations (CE2.5 and CE5.0). In the peritoneal fat, CE1.25 increased MT:18S DNA, increased citrate synthase activity, and decreased the average adipocyte area when compared to the STZ group. CE1.25 also induced fat beigeing by upregulating gene expression levels of UCP1 and Cidea. XIX Furthermore, an increase in gene expression levels of perilipin, HSL, and TFAM showed increased fat mobilization and metabolic activity. In the intramuscular fat, CE1.25 also reduced the average adipocytes area. However, a different mechanism of action was observed where CE1.25 did not induce fat beigeing, but instead increased both citrate synthase and CPT1 enzyme activities and gene expression levels of HSL, thereby indicating increased fat oxidation and mitochondrial activity. , Thesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Sciences, 2023
