- Description: This is a mixed method research study that aims to investigate the Geometry Proficiency of Grade 11 learners in rural senior secondary schools of Mount Frere in Alfred Nzo Education District, in the Eastern Cape, South Africa. The study is oriented in interpretive paradigm and utilizes both quantitative and qualitative methods. The study was conducted in 10 rural senior secondary schools that were selected using convenient sampling technique. The quantitative part employed a survey that consisted of 19 mathematics teachers and total of 162 Grade 11 learners. Out of 10 rural senior secondary schools, three were purposively selected with their three (3) classes, three (3) Mathematics teachers and three (3) Heads of Mathematics and Science Divisions for qualitative part. Questionnaires were administered to 19 Mathematics teachers and 162 learners. Three teachers in three different schools were observed as they taught Grade 11 learners Circle Geometry in their respective classes. Qualitative data through observations, interviews and document analysis were gathered. The study targeted to provide an in-depth understanding of the Geometry Proficiency of the learners in the sample. The quantitative data were analysed using IBM Statistical Package for Social Sciences (SPSS) Version 22. The study found the failure of teachers to instate teaching strategies appropriate for generating acceptable levels of Geometry Proficiency and a myriad of challenges that were experienced by learners. These included inadequate preparation by teachers, lack of learning and teaching support materials, the manner in which Geometry was taught, learners' problem solving skills, absenteeism, illiterate and impoverished parents, and failure to understand the utilitarian value of Geometry. The study recommends that Van Hiele’s levels of Geometric thought as well as the Van Hiele’s phases of learning be implemented in the schools particularly in rural schools. These should be integrated with appropriate teaching strategies and learner teaching support materials, particularly the ones that include practical investigations. , Thesis (D.Ed) -- Faculty of Education Sciences, 2020

- Description: Type 2 diabetes mellitus (DM) is a frequent adverse effect of antiretroviral drugs for those who are on ARVS. People with type 2 DM can suffer multiple complications that hinder the quality of life. In South Africa research has shown significant increase in neuropathy, heart and kidney diseases among patients living with type 2 DM and HIV/AIDS compared to DM without HIV. Accessed knowledge lacked consistency on the predictors of DM in HIV/AIDS patients with regards to the type of ARVS with higher risks of DM. Research needed to be done to find the determinants of type 2 DM in HIV/AIDS context. The purpose of this study was to describe the determinants of type 2 DM among HIV/AIDS patients on ARVS in the OR Tambo District, SA in order to develop intervention strategies to mitigate the long-term effects of type 2 DM. A quantitative research methodology using a case control retrospective study was used. A sample of 177 (33%) cases with HIV/AIDS and type 2 DM was selected using a one stage stratified sampling with allocation proportional to size of each stratum of the four sub-districts of OR Tambo District. Two non-diabetic patients with HIV/AIDS were selected as controls per case unpaired and totalled up to 354 (67%) controls. A self-administration questionnaire adopted from the WHO (2011) STEPwise surveillance tool for chronic diseases was used for data collection. Stata (standard version 13.0, Stata Corp., Lakeway Drive USA) was used for data management and analysis. Findings of the study revealed determinants of type 2 DM grouped as the socio-demographic determinants; tertiary education and marital status, levels of physical activities; lack of vigorous activity and sport, types of diets; high fruits and vegetables and healthy eating out at restaurants, arterial blood pressure; lack of routine BP check and known HPT and types of ARVS used in HIV/AIDS therapy. Compared with patients who received FDC, the risk of type 2 DM was 43 times and 22 higher when a tri-therapy regimen contained Ritonavir and Lopinavir respectively . The majority of DM patients (n=177) were diagnosed type 2 DM after ARVS at n=108 (61%). In managing the diabetic patients a shift from a single disease to multiple-chronic disease focus is required to mitigate the complex drug interactions that exist in the control of NCDs such as HIV/AIDS, DM, HPT and other long-term diseases. The HIV/AIDS and type 2 DM awareness and care intervention strategy is recommended as healthy lifestyle, monitoring of side effects and drug interactions, enhanced FDC roll out and elimination of unsafe ARVS to improve the health outcomes of type 2 DM patients in an HIV/AIDS context in OR Tambo District.

- Description: This study investigated whether the funding of section 21 schools improves the quality of teaching and learning in six schools in the Mthatha Education District, in the Eastern Cape Province of South Africa. Despite the large funds that are pumped into schools by the Department of Education, the schools appear to be under resourced, underdeveloped and therefore underperforming. The researcher used the theories of school improvement to ground this study and to investigate whether the schools improve or not, and are offered support where necessary, as they are continuously being funded by the Department of Education. The study had these objectives: To investigate how the funds are spent by Section 21 schools in the Mthatha district of Education: to assess whether the SGB manages the spending of funds and whether there is any collaboration between the Principal and the SGB in financial issues and: to evaluate whether Procurement procedures are followed when purchasing. Systematic random sampling, amongst 6 schools, has been conducted. A questionnaire was administered to the school Principals, 2 Finance committe members, 1 Educator and 1 learner and SGB chairpersons from each of the 6 schools. Thus, both qualitative and quantitative methods of inquiry were used in this study. 3 Junior Secondary and 3 Senior Secondary schools were considered in the sample. The findings that emerged were a lack of capacity, on the part of SGBs to monitor recurrent allocations as stipulated in the South African Schools Act (No 84 of 1996). Another factor that emerged was that schools still need training and workshops on procurement procedures. Also evident was that there appeared to be little evidence of collaboration between principals and SGBs, especially in financial matters. Finally, recommendations and suggestions were made that schools need to be provided with a series of workshops on procurement procedures and policies. SGBs were to be capacitated so that they could be on board on financial management. The principals were to be encouraged to cooperate and be transparent on financial matters especially since, as stipulated in SASA, as an official of the Department of Education, the principal has a responsibility to advise the governing body when they issue instructions or act in a manner that contravenes departmental instructions or policy.

- Description: Most invertebrate species are becoming extinct due to habitat loss and alien plant invasions. Hence this study aimed at determining the response of invertebrates to alien and indigenous vegetation within protected areas in the King Sabatha Dalindyebo (KSD) Local Municipality, Eastern Cape, South Africa. Invertebrates were collected using pitfall traps, during 12 sampling occasions from May 2010 to April 2011 numbers of sampling sites. Although the sampling method was adapted to collecting ground dwelling invertebrates, opportunistic flying invertebrates were also collected. A total of 7 flying invertebrate orders, 25 families, 34 species and 248 individuals were attracted to traps while 5 orders, 19 families, 50 species and 1976 individuals of soil surface-dwelling invertebrates were collected. ANOVA test showed no significant differences (p > 0.05) in species richness and abundance across sites for soil surface-dwelling invertebrates. Bray-Curtis similarity measures in PRIMER and correspondence analysis (CA) in CANOCO showed that sampling units with alien invasive plants shared most soil surface-dwelling invertebrate species at ± 75% level of similarity. Sampling unit A from the Mix alien (MA) site shared most species with indigenous vegetation sites. Sampling units from indigenous vegetation sites shared most species at ± 65% level of similarity. Multivariate analysis using CANOCO indicated that certain site variables such litter depth influenced the distribution of soil surface-dwelling invertebrates across sites. The study provided preliminary data and information for promoting invertebrate biodiversity conservation within protected areas (Nduli and Luchaba Nature Reserves) of the KSD Local Municipality. Key words: invertebrates, indigenous vegetation, alien vegetation, Lantana camara, Acacia mearnsii, and Eucalyptus.

- Description: ABSTRACT Haliotis midae Linnaeus, 1758 is the largest among six abalone species found in South Africa, making it the second largest around the world. This species is highly sought after due to its size and delicacy. However, it’s expensive formulated feed and slow growth rate has prompted increasing research on improving its growth using natural feeds. Inclusion of fresh and dried macroalgae (Ulva lactuca Linnaeus, 1753 and Gracilaria gracilis Irvine & Farnham, 1995) onto artificially formulated feed (Abfeed®) was tested on the growth of juvenile weaning H. midae. Therefore the three treatments were referred to as: Abfeed®, Abfeed® plus fresh seaweed and Abfeed® plus dried macroalgae. The growth of U. lactuca and G. gracilis was also compared using four different liquid fertilizers. Results revealed that inclusion of dried macroalgae was the best feed as it showed better consumption (92±0.48%) and growth (SGR = 2.9±0.04 % g. day-1 , DISL = 12.04±0.48 µm. day-1 and CF= 0.97±0.07 g. mm-1 ) rates. The study exhibited no differences in survival rate and feed conversion ratio in all the treatments used. Enriching with different fertilizers at 10 % concentration revealed that Nutrisol® promoted the best growth for U. lactuca among four different fertilizers used while Kelpak® yielded the best growth for G. gracilis. Increasing concentrations to 20 % resulted in Nitrosol® performing better than other fertilizers in U. lactuca growth while G. gracilis grew best in Nitrosol® and Kelpak®. This study therefore demonstrates the potential to develop abalone feeds with inclusions of dried macroalgae meal. Abfeed® as a diet alone performed poorly against the feeds tested as expected due to many previous studies favoring mixed diet. The study further revealed that macronutrient (nitrogen and phosphorus) is the limiting ii factor for macroalgal growth and their level in culture system is very critical as it determines growth rate. Key words: Consumption rate, Feed conversion ratio, Fertilizer, Formulated feed, Survival rate

- Description: Abstract text To effectively reduce HIV transmission to newborns requires a reduction of HIV prevalence among pregnant women and a full understanding of its epidemiology. There is however, a literature gap: few recent HIV studies focus on women attending antenatal care in rural areas in South Africa. A Cross-sectional study of women attending antenatal care in four Primary Care facilities was conducted. An interviewer-administered questionnaire to collect information on socio-demographic characteristics and medical history was used. Binomial logistic regression analyses were used to determine factors associated with HIV and to estimate the prevalence ratio (PR). The 95% confidence interval (CI) is used for precision of estimates; p≤0.05 for statistical significance. A total of 343 participants were recruited. Most participants (n = 341 or 99.42%; CI: 97.91 – 99.93) knew their HIV status. The antenatal HIV prevalence was 38.19% (CI: 33.17 – 43.48). Participants older than 40 years were 3.99 and 3.81 times more likely to be HIV positive compared to teenagers (PR = 3.99; CI: 1.11 – 14.30; pstxvalue = 0.034) and those in the 20-29 age group (PR = 3.81; CI: 1.07 – 13.60; pstxvaluevalue = 0.039) respectively; and this was statistically significant. Unemployed participants were 34% (PR = 1.34; CI: 1.16 – 1.55; p-value less than 0.0001) and 41 percent (PR = 1.41; CI: 1.23 – 1.61; p-value less than 0.0001) more likely to be HIV positive when compared to tertiary students and self-employed individuals respectively. The antenatal HIV prevalence remains high and is increasing in this population. However, findings suggest a changing and maturing epidemic. , Thesis (MMED) -- Faculty of Health Sciences, 2019

- Description: Citrus limon commonly known as lemon is the third most cultivated citrus genus in South Africa mainly cultivated for its juice. This study aims at analysing the chemical composition of Citrus limon waste (leaf and peel) and evaluation of their insecticidal properties. Leaves and peels of Eureka lemons were collected from three South African citrus farms (Addo, Riverside and Mystic), while Lisbon lemons were only collected from two citrus farms (Addo and Riverside) in 2017 and 2018. A total of 36 essential oils were extracted using the Clevenger like apparatus. Analyses of these oils were done using GCMS. An infusion extract of C. limon was prepared according to the standard method and subjected for phytochemical screening to detect and quantify secondary metabolites present. D-Limonene was the major compound identified in all the 36 oils from Eureka and Lisbon peels and leaves (27.9-74.8%). Other dominant compounds identified in Eureka leaf and peel oils were -pinene (5.8-13.2%), -terpinene (4.8-6.7%), geranial (4.0-15.4%), z-citral (6.7-11.7%), sabinene (4.5-6.3%), nerol (4.0-5.4%) and neryl acetate (6.3-9.5%). Some compounds were however present only in some oil such caryophyllene (6.5%) in Mystic dry leaf oil, geraniol (8.0%) in Addo dry leaf oil, as significant compounds. Lisbon leaf and peel essential oils -pinene (4.4- 11.8%), p-cymene (4.2-6.3%), -terpinene (4.4-6.9%), geranial (8.6-17.3%), z-citral (7.1-13.6%), neryl acetate (4.7-9.1%) (5.4-5.9%) were the other prominent peaks identified in the oils. These C. limon essential oils were further tested for insecticidal activities against maize weevils by conducting repellent assay, fumigant assay and contact toxicity; also plant viii powder was used against maize weevils. In general, for all the bioassay, mortality of the insect increased as the contact days with the oil increased. Contact toxicity assays of C. limon peel essential oils were most effective against S. zeamais in which all weevils were dead by day 3 (100% mortality) at 300 μL, while at other concentrations (50, 100, 200 μL) over 50% mortality was observed. The fumigant potential was high with the peel oil with over 50% mortality at 32 and 40 μL in day 4. The oil had moderate repellent effect on the maize weevil. Riverside Eureka dried powder peel was the most effect in all. These results unveil the medicinal potential of South African citrus waste in post-harvest crop protection and good sources of some chemical compounds which are of medicinal value. Furthermore, this study also reveals the economic potential of these wastes in job creation.

- Description: Citrus limon commonly known as lemon is the third most cultivated citrus genus in South Africa mainly cultivated for its juice. This study aims at analysing the chemical composition of Citrus limon waste (leaf and peel) and evaluation of their insecticidal properties. Leaves and peels of Eureka lemons were collected from three South African citrus farms (Addo, Riverside and Mystic), while Lisbon lemons were only collected from two citrus farms (Addo and Riverside) in 2017 and 2018. A total of 36 essential oils were extracted using the Clevenger like apparatus. Analyses of these oils were done using GCMS. An infusion extract of C. limon was prepared according to the standard method and subjected for phytochemical screening to detect and quantify secondary metabolites present. D-Limonene was the major compound identified in all the 36 oils from Eureka and Lisbon peels and leaves (27.9-74.8%). Other dominant compounds identified in Eureka leaf and peel oils were -pinene (5.8-13.2%), -terpinene (4.8-6.7%), geranial (4.0-15.4%), z-citral (6.7-11.7%), sabinene (4.5-6.3%), nerol (4.0-5.4%) and neryl acetate (6.3-9.5%). Some compounds were however present only in some oil such caryophyllene (6.5%) in Mystic dry leaf oil, geraniol (8.0%) in Addo dry leaf oil, as significant compounds. Lisbon leaf and peel essential oils -pinene (4.4- 11.8%), p-cymene (4.2-6.3%), -terpinene (4.4-6.9%), geranial (8.6-17.3%), z-citral (7.1-13.6%), neryl acetate (4.7-9.1%) (5.4-5.9%) were the other prominent peaks identified in the oils. These C. limon essential oils were further tested for insecticidal activities against maize weevils by conducting repellent assay, fumigant assay and contact toxicity; also plant viii powder was used against maize weevils. In general, for all the bioassay, mortality of the insect increased as the contact days with the oil increased.

- Description: Workplaces are required by law to provide HIV and AIDS workplace programmes to educate and prevent the spread of HIV, and stigmatisation and discrimination against workers infected or affected by HIV and AIDS. This study was a descriptive cross-sectional study conducted in the public and private sector at Mt Fletcher in the Eastern Cape Province. It aimed at assessing the availability and implementation of HIV and AIDS workplace programmes at Mt Fletcher. The study’s objectives were: to assess knowledge of HIV and AIDS among employees; to determine the availability of HIV and AIDS psychosocial programmes; to assess the employees’ knowledge on HIV and AIDS workplace guidelines that prevent stigma and discrimination. This was a quantitative study. A self-administered questionnaire was used to collect data. A total of 81 respondents from both public and private sectors participated in the study. Stratified random sampling was used to select participating workplaces. Simple random sampling was used to select respondents. The findings indicated that both public and private sector workplaces have HIV and AIDS programmes. However, all private sector workplaces at Mt Fletcher had no onsite clinic as required, but use the local public HIV and AIDS clinics. However, 24% of public and 23% of private sector employees had no knowledge of the existence of the HIV and AIDS programmes at their workplaces. About 13% of public and 10% of private sector employees indicated that stigmatisation and discrimination against people living with HIV and AIDS was a problem in the workplace. They also indicated that they would not disclose their HIV status to their employers because they were afraid of losing their jobs. The lack of disclosure further disadvantages workers living with HIV as they do not get the support they deserve from their employers. Furthermore, lack of support, stigma and discrimination have an impact on the performance and productivity of the infected and affected employees and therefore affecting the expected output of their workplaces.

- Description: The purpose of this study is to identify why and how the females are marginalized in senior positions. This qualitative case study explores the experiences of women leaders as school principals in Rural Secondary Schools of Butterworth District. It was undertaken in two conveniently selected Rural Secondary Schools of Butterworth that are led by female principals. The data was collected through the use of interviews. This data was collected directly from the female principals. The findings of this study clearly identified that gender has more effectively worked against the women’s success as leaders. Females start to encounter a challenge from even being shortlisted for the senior positions and that becomes worse in being appointed as leaders. Even those few women appointed as leaders are being undermined by fellow colleagues as well as communities around them. It was recommended that in order to improve women representation in educational leadership, great efforts must be made in addressing a number of issues. A significant step would be to disseminate law on gender equality widely written throughout the country to raise public awareness about gender issues. Women should be encouraged and supported to participate in leadership. Also women should be prepared by being offered leadership preparation and leadership programmes so that they feel more self-confident and function effectively once appointed.

- Description: Background: Dysfunction of the vascular endothelium is an early finding in the progression of cardiovascular disease and is closely related to clinical events in patients with obesity and hypertension. Vascular function is mediated by nitric oxide (NO) and endothelin (ET-1) which serve as natural counterparts. The aim of the study was to determine the physiological effects of HIV infection, blood pressure and body composition on the changes of ET-1 and NO and association between ET-1 and NO. Methods and results: This was a descriptive and comparative study. A Quota sample method was used. The study population consisted of 154 participants categorized into the following groups: 57 HIV negative participants (A), 40 HIV positive not on treatment participants and 57 HIV positive on treatment participants. Enzyme immunoassay kit was used for the quantitative determination of ET-1 and Nitrate/nitrite colorimetric assay kit was used for the determination of NO. Anthropometric measurements, body composition were determined. Hemodynamic measurements were also taken into account. Results: Resting metabolism, waist circumference (WC) and hip circumference had low mean levels in both HIV positives groups compared to HIV negative group. On lipid profiles visceral fat (VF), whole fat (WF) had low mean levels but skeletal muscle fat (SMF) showed the highest mean levels in both HIV positive groups. All the blood pressures between HIV groups were on a normal range scale. Mean values of endothelin and nitric oxide are increased in HIV positive not on ART and HIV (+) on ART compared with the HIV negative group. Conclusion: NO, ET-1, ART and HIV itself were associated with the pathogenesis of endothelial dysfunction in persons with HIV infection. Elevated endothelial markers namely ET-1 and NO can lead to improvement of endothelium dependent relaxation to some extent but not completely. Although these markers have deleterious effect on the endothelium but can also serve as up-regulator of hypertension. Key words: HIV-infection, antiretroviral therapy, endothelial dysfunction, Endothelin1 (ET-1), nitric oxide (NO), blood pressures (BPs). , Thesis (MSc) -- Faculty of Health Sciences, 2015

- Description: The study aimed to investigate the key performance factors in circumventing the effects of sanctions imposed by the Gulf Cooperation Council (GCC) on Qatar. A case study of Qatar Airways (2016-2020) in the form of desktop analysis/document review coupled with observation was carried out. Effects of sanctions identified included the closure of air corridors, increased operational costs, and in-access to services from certain insurance companies and travel agencies. From the results, management was observed to have implemented the following measures to caution the airlines from the effects of sanctions: close monitoring of flights, integration of all operations activities, network expansion, effective marketing, continued engagement with the sanction imposers, consistency in terms of management action and the messages communicated and fighting sanctions legally through the courts. Key Success Factors (KSFs) were extracted from these management initiatives credited with the continued success of Qatar Airways which included marketing, Corporate Social Responsibility (CSR), service quality, marketing, security, resources availability, technology, synergies, diversification, and government support. From the management initiatives, Key Performance Indicators (KPIs) were also extracted which acted as barometers to indicate the progress being made by implementation of these management initiatives in the fight against sanctions. These included accolades, passengers/cargo, fleet size, revenue, employees, and crisis indicators. These findings from the study can be used by other airlines that may find themselves under sanctions. , Thesis (MCom) -- Faculty of Commerce and Administration, 2021

- Description: The National Department of Education has undergone drastically changes from 1994. This study is about teacher‘s perceptions of the implementation of NCS. This study seeks to reveal the perception, feelings and the beliefs of teachers towards the implementation of the New Curriculum Statement in Mount Fletcher District of Eastern Cape Province. A mixed mode approach was conducted in this study in a form of quantitative and qualitative methods. Stratified random sampling (schools) and purposive sampling was used to draw the participants (teachers) from different High schools in Mt Fletcher. Data was analyzed following this pattern of organizing, transcribing, coding, establishing themes or categories, structuring, findings which paved way for the recommendations of this study and conclusion. The findings of this study reveals that teachers are just shooting in the dark in the sense that few teachers are implementing NCS successfully using their own methods and strategies of teaching and learning with a very limited clear understanding of the policy documents related to NCS principles while most schools and teachers are implementing through trial and error method, policy documents are just ―blue print to them as they received no clarity of them. And above all, teachers are lamenting on systematic, pedagogical and societal challenges that hindering the process of thorough implementation of NCS. Based on the findings the researcher recommends that the National Department of Education must pay attention for the Systemic challenges e.g. thorough training of teachers on methods of teaching and learning so that they can be able to understand the policies and methods of teaching and learning. She also recommends that whenever the NDoE is introducing new reforms on education, advocacy and awareness must reach the level of implementers not the understanding of the delegates. The NDoE again must pay attention to overcrowded classrooms and classes that are not conducive for teaching and learning (poor infrastructure), lack of basic and appropriate learning materials; Societal challenges e.g. Lack of parental support and Pedagogical challenges e.g. inappropriate teaching methods as well as learning and teacher support material, unqualified and under-qualified teachers, inappropriate assessment procedures, lack of support for teachers.

- Description: Diarrhea diseases remain one of the greatest health problems in many parts of the world. In some cases, the disease is mild and self-limiting; however, the symptoms may be very severe in the elderly and young children (Smith and Cheasty, 1998), as well as in immune compromised patients such as HIV/AIDS patients. The disease is one of the hallmarks of HIV/AIDS in developing countries and is also a cardinal clinical manifestation of water borne infections (Obi et al., 2007). According to a World Health Organization report (WHO, 2004), diarrhea was rated second, after respiratory infections out of the eight deadliest diseases worldwide and was responsible for 1.8 million deaths per year. This infectious disease which can cause dehydration is primarily a symptom of gastrointestinal infection, but chemical irritation of the gut or non-infectious bowel disease can also result in diarrhoe. Studies have shown that the predominant causative agents of acute and persistent diarrhoe are Gram-negative rods such as Escherichia coli, Vibrio cholerae, Aeromonas, Campylobacter, Salmonella species, Shigella species, Plesiomonas shigelloides and Yersinia enterocolitica (Obi et al., 1995, 1998, 2003; Lainson and Silva, 1999; Coker et al., 2002; Oyofo et al., 2002). Aside from bacterial agents of diarrhoea, other causative pathogens include protozoa such as Giardia lamblia and Cryptosporidium parvum; viruses such as norwalk virus and rota virus. Although fungal agents such as Candida have been shown to be prevalent in children with diarrhoe (Enweani et al. 1994), a more recent study (Forbes et al., 2001), associated higher Candida counts with recent antibiotic use. Faecal concentrations of Candida were higher in patients with diarrhoe, but the study confirmed no association between faecal candida or other yeasts and diarrhoe. Norwalk viruses, calci-like viruses and rota viruses are the major viral agents of diarrhoe. According to Parashar et al., (2006), rota virus is the leading cause of diarrhoe hospitalisation among children worldwide, causing 440,000 annual deaths in children under 5 years of age.

- Description: Diarrhea diseases remain one of the greatest health problems in many parts of the world. In some cases, the disease is mild and self-limiting; however, the symptoms may be very severe in the elderly and young children (Smith and Cheasty, 1998), as well as in immune compromised patients such as HIV/AIDS patients. The disease is one of the hallmarks of HIV/AIDS in developing countries and is also a cardinal clinical manifestation of water borne infections (Obi et al., 2007). According to a World Health Organization report (WHO, 2004), diarrhea was rated second, after respiratory infections out of the eight deadliest diseases worldwide and was responsible for 1.8 million deaths per year. This infectious disease which can cause dehydration is primarily a symptom of gastrointestinal infection, but chemical irritation of the gut or non-infectious bowel disease can also result in diarrhoe. Studies have shown that the predominant causative agents of acute and persistent diarrhoe are Gram-negative rods such as Escherichia coli, Vibrio cholerae, Aeromonas, Campylobacter, Salmonella species, Shigella species, Plesiomonas shigelloides and Yersinia enterocolitica (Obi et al., 1995, 1998, 2003; Lainson and Silva, 1999; Coker et al., 2002; Oyofo et al., 2002).

- Description: The digestive system of Tilapia sparrmanii, Smith 1894, a small sized cichlid fish widely distributed in Southern Africa and of little economic importance was studied by light microscopy as part of establishing base-line data for future references. The gut in T. sparrmanii was a simple long coiled tube. With greater fish length, the gut progressed into a complexly-coiled definitive form. Strong linear correlations were observed between fish size and gut length. The esophagus was relatively very short and the stomach sac-like and small. Histologically, T. sparrmanii displayed a stratified esophagus epithelium with goblet cells which displayed both neutral and acid mucus at the anterior region. The stomach of T. sparrmanii was divided into three distinct segments the cardiac, fundic, and pyloric portions. The study revealed that the gastric wall is composed of several tunicae: mucosa, submucosa, muscularis and serosa. The tunica mucosa was thrown up into a number of high longitudinal folds projecting into a lumen. The mucosal surface had surface epithelial cells. The epithelium in this region was simple columnar devoid of goblet cells, with glandular regions in the lamina propria. The mucosa of the fundic region had gastric pits lined by columnar epithelium, and simple tubular glands filled most of the lamina propria. The pyloric part of the stomach was very short and its mucosa was slightly folded and devoid of both gastric pits and mucous glandular cells. The lining epithelium of this portion of the stomach was simple columnar and a few goblet cells were seen at its junction with the first part of the intestine. The tunica muscularis of the stomach contained skeletal muscle in the initial and terminal regions, usually intermingled with smooth muscle fibres. Skeletal muscle fibres were also observed in the first portion of the proximal intestine, iii near the junction with the stomach. Gastric pits were present as invaginations of the mucosal surface. Their epithelium secreted both neutral and acid mucins. Simple, straight, tubular unbranched gastric glands occupied most of the surface of the mucosa, and were lined with cells that had eosinophilic granules. The tunica muscularis of the stomach consisted of skeletal muscles usually mixed with smooth muscle fibres. Also, the stomach was separated from the proximal intestine by a pyloric sphincter. Results demonstrate that the intestine was a relatively undifferentiated muscular tube lined with a simple columnar epithelium interspersed with goblet cells. The proximal region had a greater surface area, as revealed by the presence of elongated mucosal ridges. The enterocytes were covered apically with uniform microvilli. The number of goblet cells were moderate in the proximal intestine and fewer in the medial intestine. All segments of the intestine contained neutral and acidic mucins. The distal intestine mucosa was thinner and less elaborately folded and consisted of columnar cells with shorter and sparser microvilli. After the intestinerectal valve, the rectum displayed lower mucosal folds, numerous goblet cells and a thicker muscularis. An ileorectal valve was observed. This confirms that separate intestine and rectum does exist in T. sparrmanii.

- Description: This dissertation is a report of the study that was conducted in rural schools of Tsolo district in Eastern Cape Province of South Africa. The study was about the relationship between union representatives and school management teams. The study was conducted because the researcher is a site steward in the present school where the researcher working and is always dealing with conflicts that usually occur between the S.M.T and Union members and has to address these issues regularly. This problem made the researcher to be interested and want to know further from other schools of what is the situation. This was done through focus group interviews and the study was qualitative research paradigm. There were questions that were drafted and participants were asked to respond according to the questions. The participants were as follows 11 SMT members and 18 union representatives. The study findings highlighted the role that SMT could play in the smooth running of the school and in addressing tensions to enhance effective work. The study also illuminated the issue of being bias among the SMT in some unions and dictatorship by S.M.T members. The study findings highlight the role the S.M.T should play and the issue of consultation before any decision should be taken as an integral part. The study also showed that there was a need for schools to know the South African legislation so as to go along with correct rules and regulations when addressing different issues.
