- Description: Mbashe River passes through three districts of Eastern Cape, South Africa, with catchments that have been modified by anthropogenic activities. To determine the effects of anthropogenic activities on the river particulate organic matter, (δ13CPOM), (δ15NPOM) and C/N ratios of particulate organic matter were investigated. Six sampling sites from three sections of the river were identified and selected according to anthropogenic activity occurring close to the river and sampled over a period of twelve months. The results indicated that different anthropogenic activities had significant effect on the POM stable isotope dynamics, resulting in uniquely distinct stable isotopes signatures varying both temporally and spatially. The C/N ratios, (δ13CPOM), and (δ15NPOM) isotopic values varied significantly (95% confidence interval) and revealed that POM was derived from different sources in the river catchment. Anthropogenic activities affected C/N ratios and δ15NPOM temporally, spatially and between river sections. The upstream was δ15NPOM depleted (4.5‰) while downstream the river δ15NPOM was enriched (5.8 ‰). The δ13CPOM values ranged from -12‰ to -32‰ temporally during the study period. The study revealed that POM was mainly derived from allochthonous sources (C/N ratios >8). The (δ15NPOM) revealed that upstream was more affected by anthropogenic activities than downstream. Our findings suggest that anthropogenic activities had more temporal effect than site to site. Further research is recommended and required to check whether isotopic dynamics observed can be replicated and determine whether the effect of anthropogenic activities is increasing or decreasing.

- Description: Children from low socio-economic communities in the Eastern Cape Province of South Africa and in South Africa at large are frequently infected by intestinal parasites. The parasites are diverse and complex pathogens that include multi-cellular helminths and single-celled protozoa. Because of this diversity, immunity to parasites is more difficult to sustain. Tuberculosis also, remains a problem in South Africa and worldwide. Infection with Mycobacterium tuberculosis can result either in the disease itself or, more commonly, latent infection. A variety of mechanisms that include both humoral and cell mediated immunity achieve host protection against mycobacterial pathogens. Macrophages and cell-mediated immunity are the primary defence mechanisms against mycobacteria. According to the literature, parasitic infections impair the body’s immune response to tuberculosis, but these diseases are not adequately researched in this province. The extent to which the school children of Mthatha are infected with intestinal parasites and latent tuberculosis, or even how their immune systems respond to these infections have not been investigated. Therefore, the immune response of school children, both of those infected and those not infected with parasites, to specific Mycobacterium tuberculosis antigens was evaluated. The present study used two study design methods: firstly, a descriptive cross-sectional design for the prevalence rates of intestinal parasites and, secondly, a case-control study for comparison of interferon gamma and T-helper 1 and T-helper 2 cytokines in parasite infected and non-parasite infected participants. A total of 137 school children participated in the survey and all were analyzed for parasites. Due to the high cost of the reagent kits, only 75 participants were included in the case-control study. Data collection methods: i) for the prevalence of intestinal parasites, formalin ethyl acetate sedimentation technique was used to process stool specimens, ii) for immune response to Mycobacterium tuberculosis antigens (measurement of interferon gamma for latent tuberculosis),the QuantiFeron TB Gold In-Tube assay was used, and iii) for the quantification of Th1 and Th2 cytokines, the Bio-Plex Pro assay was used. Out of 137 school children analyzed, 66.4% (91/137) were positive for parasites (ova and cysts). The most prevalent parasite was the pathogenic helminth, Ascaris lumbricoides at 21.9% (30/137), followed by Trichuris trichiura at 8.8%. The pathogenic protozoa, Giardia lamblia and Blastocystis hominis were both at 2.9% (4/137). The non-pathogenic protozoa, Entamoeba coli and Endolimax nana had high prevalence rates at 32.1% (44/137) and 29.2% (40/137) respectively. Associations between parasitic infections and sociodemographics showed a significant difference in participants whose parents had a low level of education and those who were unemployed (P = 0.004; P = 0.005 respectively). Out of 75 participants analyzed for tuberculosis, 53.3% (40/75) were positive. In conclusion, the present study demonstrates high prevalence rates of parasitic as well as latent tuberculosis infections in Mthatha. The study also showed that intestinal parasites, especially helminths, interfere with immune responses to TB by down-regulating Th1 response leading to reduced production of interferon gamma, a cytokine that mediates protection against TB.

- Description: The purpose of this study was to investigate the factors influencing enrolment in rural primary schools in one Circuit in Port St. Johns CMC in OR Tambo Coastal Education District. The literature review looked into each of the following aspects of factors influencing enrolment in rural primary schools: challenges resulting in policy issues, the challenge of infrastructure, other factors that influence enrolment in rural school and strategies to overcome enrolment challenges in rural schools. The study was qualitative in nature and employed case study research design. Convenient sampling was used to select four rural primary schools in one Circuit in Port St. Johns Circuit Management Centre (CMC) in OR Tambo Education District. The principal, one (1) educator, one (1) parent and one (1) learner were purposively selected from each school and this made a total of sixteen (16) participants. Face-to-face individual interviews were conducted to gather data about the views and opinions of the participants. Data were analysed using the interpretational analytical strategies. Themes were drawn from the responses of the participants. The major findings were:When the number of learners decreases, the number of educators is also reduced proportionately as a results educators have to take more subjects.There was a negative effect of the relocation of parents, there was poor quality of teaching and learning, the effect of instability crippled normal functioning of the school, there was poor school management as the schools were hit by having no principals due to internal disputes, there were disruptions of teaching and learning due to instability in rural primary schools. The main recommendations are: Rural primary schools should gradually improve the quality of teaching and learning provisioning and arrest the decline in enrolment;At least each class should have an educator, so that discipline can be maintained in all classes; Given the highly technical nature of the process involved in determining the PPN of schools, the DBE, the Provincial Education Departments as well as educator unions should as a matter of priority engage in a massive campaign to capacitate principals on the application of the PPN and its related formula; An audit into the schools' physical infrastructure be conducted to redress the meaningful pedagogical environment of teaching and learning.

- Description: This study aimed at investigating the conceptions and alternative conceptions regarding the optical phenomena ‘reflection’, ‘refraction’ and ‘total internal reflection’ amongst Grade 11 learners at a selected school in Mthatha, Eastern Cape, South Africa and developing remedies to enhance their conceptual understanding of this area. The study adopted a quasi-experimental pre-test – post-test design. To enhance the credibility of the findings of the study, the data were collected using mixed methods (both questionnaires and interviews). The questionnaires developed for the study were 4 tier Optics Diagnostic Instruments (4ODIs) which were designed in such a way that both qualitative and quantitative data could be collected. To explore the findings from the pre-tests, face-to-face interviews with selected learners from both the groups were conducted. This stage was followed by the design an optics teaching module which aimed at enhancing the experimental group learners’ conceptual understanding of the optical phenomena, whereas the comparison group was taught in the traditional teaching method. To test the effectiveness of the designed teaching module, the 4ODIs were administered as post-tests to both groups. To enhance the credibility of the findings from the post-tests, face-to-face interviews were conducted with some selected learners from the experimental group. Since the aim of the interviews at this stage was to test how the designed optics teaching module helped the experimental group learners in enhancing their conceptual understanding, the comparison group learners were not interviewed at this stage since they were taught in the traditional teaching method. The quantitative analyses were carried out using Microsoft Excel and the statistical software, IBM SPSS Version 20. The qualitative analysis was carried out manually by coding and categorizing the learners’ responses from the questionnaires and the interviews. The item analysis of the 1st tiers was carried out using Microsoft Excel. The statistical comparisons of the test scores of the 1st tiers of the tests (pre-test – post-test comparison of both the groups and the experimental group – comparison group comparison of both the pre-tests and the post-tests) were performed using t-tests (independent samples t-test and paired samples t-test). The 2nd tiers (learners’ confidence levels in their responses to the corresponding 1st tiers) and the 4th tiers (learners’ confidence levels in their responses to the corresponding 3rd tiers) were analysed by (using SPSS) calculating measures of central tendencies of their responses. The 3rd tiers (open-ended questions) and the interviews were analysed manually by coding and categorizing learners’ responses. Before the implementation of the optics teaching module, both the experimental and the comparison groups were found to hold a variety of alternative conceptions about the optical phenomena. Moreover, the performances of both the groups were the same. It was also found that the learners from both the groups were not confident when they approached the pre-tests. The qualitative analyses of the learners’ responses to the 3rd tiers and the interviews suggested that most of the correct responses given by the learners to tier-1 of the pre-test questionnaires originated from a faulty or vague understanding of the scientific concepts. Moreover, some of the incorrect responses identified could not be considered as alternative conceptions because of the very low confidence levels the learners displayed in these responses. Such responses were categorized as ‘errors due to lack of knowledge’. The analyses of the post-test questionnaires, and face-to-face interviews conducted immediately after the post-tests, revealed that the experimental group outperformed the comparison group in terms of their conceptual understanding of the optical phenomena. In other words, the number of experimental group learners who held scientifically-accepted concepts increased for some questions of the post-tests and in some other questions, the experimental group learners developed new scientific understanding of many situations with regard to the optical phenomena. To conclude, the findings of the study proved that the Grade 11 learners in the selected school held a variety of alternative conceptions and errors due to lack of knowledge. However, the optics teaching module, which was designed by taking into consideration the learners’ prior knowledge regarding the particular learning area, could remedy most of the alternative conceptions and errors which were merely due to lack of knowledge.

- Description: This study aimed at investigating the conceptions and alternative conceptions regarding the optical phenomena ‘reflection’, ‘refraction’ and ‘total internal reflection’ amongst Grade 11 learners at a selected school in Mthatha, Eastern Cape, South Africa and developing remedies to enhance their conceptual understanding of this area. The study adopted a quasi-experimental pre-test – post-test design. To enhance the credibility of the findings of the study, the data were collected using mixed methods (both questionnaires and interviews). The questionnaires developed for the study were 4 tier Optics Diagnostic Instruments (4ODIs) which were designed in such a way that both qualitative and quantitative data could be collected. To explore the findings from the pre-tests, face-to-face interviews with selected learners from both the groups were conducted. This stage was followed by the design an optics teaching module which aimed at enhancing the experimental group learners’ conceptual understanding of the optical phenomena, whereas the comparison group was taught in the traditional teaching method. To test the effectiveness of the designed teaching module, the 4ODIs were administered as post-tests to both groups. To enhance the credibility of the findings from the post-tests, face-to-face interviews were conducted with some selected learners from the experimental group. Since the aim of the interviews at this stage was to test how the designed optics teaching module helped the experimental group learners in enhancing their conceptual understanding, the comparison group learners were not interviewed at this stage since they were taught in the traditional teaching method. The quantitative analyses were carried out using Microsoft Excel and the statistical software, IBM SPSS Version 20. The qualitative analysis was carried out manually by coding and categorizing the learners’ responses from the questionnaires and the interviews. The item analysis of the 1st tiers was carried out using Microsoft Excel. The statistical comparisons of the test scores of the 1st tiers of the tests (pre-test – post-test comparison of both the groups and the experimental group – comparison group comparison of both the pre-tests and the post-tests) were performed using t-tests (independent samples t-test and paired samples t-test). The 2nd tiers (learners’ confidence levels in their responses to the corresponding 1st tiers) and the 4th tiers (learners’ confidence levels in their responses to the corresponding 3rd tiers) were analysed by (using SPSS) calculating measures of central tendencies of their responses.
