- Description: The aim of the study was to explore the experiences of student nurses regarding the implementation of CBE and allow them to tell their story of how CBE impacted to their academic experience. Purposive non-probability sampling was the method of choice. The following research question guided this study: What are the experiences of nursing students at the nursing college on the implementation of CBE as a teaching-learning strategy? The participants in this study were the fourth year students registered in the four year diploma and have been exposed to CBE, according to regulation 425 of the Nursing Act, 2005(Act No.33 of 2005). Fifty (50) students voluntarily participated in the focus groups discussions. Data analysis was done concurrently with data collection. Data was analysed manually as it was categorised into themes, categories, and subcatagories. For this study, a category system/ template was developed to code the data according to the categories, therefore related concepts were grouped together to facilitate the coding process. The final analysis led to the development of a report presenting the interpretation and presentation of results. RESULTS The study results revealed that students had benefited from CBE as a teaching learning strategy. Furthermore, participants reported that CBE had an impact in their training in terms of acquisition of skills, personal and professional growth and correlation of theory to practice. Discussions of findings, along with recommendations for practice conclude the study. Suggestions might be made to improve ways in the implementation of CBE in the nursing college

- Description: Significant changes have occurred in South Africa during the past decades in household saving and borrowing behaviour. The rapid increase in South Africa’s household debt over the last twenty years has been an international phenomenon. In most countries, household debt increased from the 1990s until the crisis of 2007–2008 before stabilising due to a recession and deleveraging. The study used an ARDL model to investigate the determinants of household debt in South Africa. Pairwise regression is used to select the most relevant variables affecting household regression in the country. The results of the study showed that consumer confidence, the bond market index and the vulnerability index have a positive effect on household debt. As consumers' faith in the performance of the economy increases, household debt also increases as expected, reflecting consumers' belief in increased future wealth. The positive influence of the vulnerability index suggests that households tend to resort to borrowing to smooth consumption when incomes and other related factors decline. It is recommended that national policy should tighten regulations around access to unsecured credit to minimise the stress on already vulnerable households.

- Description: Biomass gasification has become a study of great interest over the years and plant biomass with cellulose, hemicellulose, and lignin found to be an ideal resource for conversion into heat and power through thermochemical processes such as gasification. The inadequate supply of the energy in the country has become critical with the national energy provider struggling to meet the energy demands of the ever growing population of South Africa. The depletion of natural resources and the unstable prices as well as the cost of transporting the fuels together with the environmental effects of burning fossil fuels are contributing factors to the energy crisis. Alternative sources of energy that are locally available, sustainable, and environmentally friendly are presently in demand as municipal organic wastes has been considered a source of renewable energy with gasification deemed one of the leading edge technologies to harness the energy. This research only studied the characteristics and kinetics of selected municipal organic waste including decaying wood, tomatoes, onions, cabbage, butternut and bones. The research did not involve the gasification process because of expenses associated with gasification processes, however, this has been considered as future studies under the conditions of available resources to carry out the actual gasification experiments. The characteristics of selected municipal organic wastes for energy conversion through gasification were actually investigated in this study and the implication of the value of each property interpreted in relation to gasification with specific reference to information available in the literature. Proximate analysis conducted on the wastes indicate that the physical properties in terms of the weight percentages of moisture, volatile matter fixed carbon and ash contents of the wastes vary considerably, especially with regards to the last three properties. The reason for this wide variation was attributed to the source of the wastes and the standard of living of the people vi in the area where the wastes were collected. However, the values obtained for these properties are within limits for the wastes to be adequately used as feedstocks in a gasification process, except for their content of ash, which was significantly high in all of the wastes for the aforementioned reasons. The ultimate analysis of the wastes as determined using the Energy Dispersive X-ray spectroscopy gave the percentage composition of the chemical elements present in the wastes, which suggest that carbon is the chief elemental constituent of the wastes. The highest carbon content of about 47% was recorded for bone due again to the reasons previously adduced. According to McKendry, 2002, the high carbon content of the wastes implies increased calorific value as well as increased gas production during gasification. A number of ash–forming elements were also found in the wastes, which included magnesium and potassium in low concentrations that does not pose any technical challenges during gasification, although their concentration may increase under high temperature gasification, which may equally result to some catalytic effect that would contribute to the overall gasification efficiency (Anukam et al., 2016). Calorific value analysis also suggests that the wastes contain reasonable amount of energy that can be converted to useful energy through gasification. Although, variation in calorific value was also noted, the highest calorific value of about 18 MJ/kg was recoded for bones, which correlates its data on the highest carbon content of all wastes. However, the data on the calorific value of the wastes suggests that the wastes are well suited for gasification by virtue of their calorific value. FTIR analysis revealed the major functional groups present in the internal structure of the wastes. The common functional groups observed were the OH group found in the band around 3600–3400cm-1 for most of the wastes; the C–H stretching band at 2970-2780 cm-1; and the C–O as well as the C–O–C observed in the region of 1740–1710 cm-1 and 1250-1220 cm-1 for all samples, respectively. Most functional group in the internal structures of gasification feedstocks function to facilitate faster vii rates of reaction and consequently faster rates of gasification that contributes to optimum efficiency under any conditions of gasification (Anukam et al., 2016). While thermogravimetric analysis established thermal parameters that are likely to have positive influence on the gasification of the wastes, kinetic investigation revealed two parameters that may also impact on the gasification of the wastes. These are activation energy and pre–exponential factor, which were found to be in good agreement with the values obtained in the literature even though variation in these parameters was noted. The values obtained for activation energy and pre–exponential factor using the Kissinger method of kinetic analysis showed a far less value for these two parameters when compared to commonly used feedstocks like wood and coal. This was a reason attributed to the chemical characteristics of the wastes, mainly their lower content of carbon compared to these two (wood and coal) commonly used fuels.

- Description: Selecting appropriate normative data for the purpose of evaluating psychometric test scores forms an integral part of the interpretative psychological assessment process. This highlights the well-known problem of utilising measures developed in the United Kingdom (UK), or the United States (US) and accepting their norms unreservedly for the practice on local populations, which questions the tests’ validity and reliability. The current study, which aimed to collect normative indicators on the Bender Gestalt Test (Second Edition), forms part of the continuing effort to develop norms for psychological tests in South Africa, and to focus on the valid and reliable use of measures within the context of South Africa’s multicultural and multilingual population groups. The participants of the research were Black isiXhosa-speaking Grade 3 and Grade 7 learners aged 8 to 9 years (N = 38 ), and 12 to 13 years (N = 23), obtaining their school education in the disadvantaged educational setting of the former Department of Education and Training (ex-DET) schools. The tests were scored according to the Bender Gestalt Test (Second Edition) manual, using the Global Scoring System. Thereafter, the raw scores were converted to Standard Scores, T-scores and Percentile Ranks using the US normative tables, according to chronological age categories. When the two groups were compared to the US norms, the results equated favourably for the present study sample. There were no significant findings in relation to the classroom size or any difference in performance between the schools who participated. The only significant difference revealed between male and female participants was with the Grade 7 sample group, where the males scored significantly lower than females on the Recall phase. These results support the prospect of the continuous revision of norms, and it is suggesting that the cognitive processes measured by this test are likely to derive from robust neurological substrates that are relatively stable across cultural groups.

- Description: This study was conducted to assess the effect of including Tenebrio molitor larvae (T. molitor L) as a protein source in different diets on broiler performance, carcass characteristics and meat quality. A total of 144 day-old Cobb-500 chicks were randomly allocated into three treatment groups, each was allocated 16 birds and reared in 9 identical pens. Experimental diets used were as follows: T1 Control (no T. molitor L inclusion); T2 and T3 contained levels of T. molitor L at 5 percent and 10 percent of dry matter (DM) intake, respectively. Body weights (BW), average daily gain (ADG), feed intake (FI), and Feed conversion ratio (FCR) were measured for the 1st experimental chapter. For the second experimental chapter; live weights (LW) of broilers were recorded before slaughter and thereafter carcass weights (CW), meat yield (weights of breast, thigh, drumstick and wing) were recorded. The dressing percentage (DP percent) was also calculated. Breast muscles were sampled for meat pH and colour measurements. The LW of birds from T1 (0 percent T. molitor L) were significantly different (P<0.05) from both T2 (5 percent T. molitor L) and T3 (10 percent T. molitor L) which were similar to each other, with T2 exhibiting the highest live weights (2166g) and the control treatment exhibiting the lowest live weights (2018.3g). In CW, T1 was significantly different (P<0.05) from T2 while it was similar (P>0.05) to T3. The dressing percent of T1 was significantly different (P<0.05) from T2 and T3 which were similar to each other, with T2 having the highest dressing percentage (78, 2 percent) and T1 having the lowest DP percent (66 percent). The breasts in T2 were significantly higher and different (P<0.05) from both T1 and T3 which were similar to each other. The drumsticks in T3 were significantly different (P<0.05) from T1 while they were similar to T2 with values with T2 having highest values. After 45 minutes of slaughter, a significant difference (P<0.05) was observed in L⃰ among all treatments. In redness (a⃰), T3 was significantly different from T1 but was similar to T2 and all treatments in this study exhibited a darker red meat, with T3 muscles exhibiting darker red colour than the other treatments. Similar results were observed in yellowness (b⃰), where the breast muscles from T3 were more yellow than the other treatments. After 24 hours of slaughter, T2 L⃰ values were significantly different (P<0.05) from both T1 and T3 which were similar to each other. It was also found that the broiler chickens given diet with no T. molitor L inclusion (T1) had lower values of BW, FI, ADG and FCR throughout the experiment than those that were in T2 and T3 with 5 percent and 10 percent T. molitor L inclusion levels, respectively. However, it was also found that although broilers with 5 percent T. molitor L inclusion (T2) in their diet had high ABW and ADG than the broilers with 10 percent T. molitor L inclusion (T3), the T3 birds compared favourably to T2 birds as they required low feed intake to reach the same slaughter weight due to high FCR. It was, therefore, concluded that T. molitor L meal can be incorporated into the diets of broilers to produce heavy birds either at 5 or 10 percent. However, although 5 percent T. molitor L inclusion yields heavier carcasses, the 10 percent T. molitor L inclusion compared favourably to 5 percent inclusion since it required low feed intake to reach the same slaughter weights and there were slight differences on meat quality attributes between the two treatments.Thus T. molitor L at 10 percent inclusion levels was the best inclusion level to enhance broiler growth performance, carcass yield, meat yield and meat quality.
