- Description: The aim of this study was to prepare composite materials based on titanium dioxide (TiO2) and silicon dioxide (SiO2), and to evaluate their photo-catalytic and antimicrobial properties. Carbon and nitrogen doped TiO2nano-particles were prepared via a sol gel synthesis, which is a simple hydrolysis and condensation technique. In situ doping was carried out using glucose and urea as carbon and nitrogen sources respectively. Doping increased the spectral response of titanium dioxide photo-catalyst, allowing it to utilise the visible region which is much wider than the UV region (about 40 % of the solar spectrum), thus making it a more efficient photo-catalyst. The carbon and nitrogen doped TiO2-SiO2nano-particles were immobilized on glass support material to allow for easy separation of the spent photo-catalyst after the photo-degradation process. Tetraethyl orthosilicate (TEOS) was employed as both a binder and precursor for silicon dioxide. A mixture of TiO2 and TEOS in a 1:1 ratio was allowed to polymerize on a glass support which had been treated with hydrofluoric acid to introduce OH groups. The prepared photo-catalytic material was characterized by FT-IR, XRD, DRS, TEM, EDX, and BET analyses. Carbon was found to be more effective as a dopant than nitrogen. It brought about a band gap reduction of 0.30 eV and a BET surface area of 95.4 m2g-1 on the photo-catalyst as compared to a gap reduction of 0.2 eV and surface area of 52.2 m2g-1 for nitrogen doped TiO2. On the other hand, introduction of SiO2 allowed utilization of visible light by the TiO2-SiO2 nano-composite leading to an improved rate of photo-degradation of both methyl orange and phenol red. However, the immobilization of TiO2 on support material made it less effective towards inactivation of E. coli ATCC 25922 bacterial cells when compared to powdered TiO2 which was able to inactivate about 98 % of the bacterial cells within an hour of treatment.

- Description: More and more people worldwide are becoming “carbon conscious”. This means they are becoming increasingly aware of the imminent adverse effects of global warming. Of late there has been an urgent drive for governments to be on the forefront of all carbon mitigation initiatives. One such drive involves the United Nations Framework Convention on Climate Change whose parties have been meeting regularly under the banner of Conference of Parties (COP) since 1995. At this conference, parties to the convention review progress made in dealing with climate change. Also key to the deliberations in such meetings are better ways of developing cleaner “carbon free” energy sources. Energy sources of this nature are commonly known as renewable energy sources. In essence global energy trends are constantly moving towards development of more renewable energy sources. It is an undeniable fact that some of viable renewable energy sources especially those with bulk capacity are usually located remotely from load centers. This inevitable reality necessitates the construction of long distance bulk power transmission corridors to link generation sites with load centers. Due to its many inherent advantages over High Voltage Alternate Current (HVAC) for long distance power transmission, High Voltage Direct Current (HVDC) is gradually winning the favor of many utilities. In fact, recent advances in HVDC technology have encouraged many utilities to explore the possibility of harnessing remotely located renewable energy sources which would have otherwise not been viable with HVAC transmission. Through the unfortunate and inevitable phenomenon known as corona effect, overhead HVDC conductors suffer real power losses to the air dielectric surrounding them. Through corona, part of the energy carried on the transmission line is expended through ionization and movement of charges in the air dielectric. This study combined physics, mathematical as well engineering concepts to review corona phenomenon around HVDC lines with specific emphasis on space charge generation and motion within ionized DC fields as well as the influence of temperature on corona discharge or power loss. Also, unlike HVAC, performance of an HVDC system relies heavily on the availability of a reliable and robust telecommunication system. One of the key ways of ensuring reliability of a telecommunication system is by making sure that reliable power supplies are in place to power remote repeater stations. A novel concept of quasi-autonomous corona-based power supply (or QC power supply in short) that works on the principle of magnetohydrodymic (MHD) power generation was developed. A small scale experiment was then designed to assess the feasibility of such power supplies. The experiment was conducted with DC supply of a maximum rated voltage of 30 kVDC and generated up to 6 VDC at an optimum ambient temperature of 23°C. These results have confirmed that with further development QC power supplies have the potential of proving reliable power to remotely located repeaters or any other small critical loads along the stretch of the HVDC transmission line. Practical HVDC transmission systems operate voltages in the excess of 500 kV. By linear extrapolation of the above mentioned results; one would expect to yield up to 100-, 120- and 160-VDC from a 500-, 600- and 800- kV HVDC system, respectively. Although the study succeeded in conceptualizing a CMHD idea upon which the novel QC power supply was developed, quite extensive and rigorous design, modeling, prototyping and experimentation processes are still required before the first QC power supply can be commissioned on a practical HVDC line

- Description: This thesis presents the development of chlorophyll, cholic acid, aflatoxin B1 molecularly imprinted polymer (MIP) particles and cholic acid MIP nanofibers for application as selective solid phase extraction (SPE) sorbents. The particles were prepared by bulk polymerization and the nanofibers by a novel approach combining molecular imprinting and electrospinning technology. The AFB1 MIP particles were compared with an aflatoxin specific immunoextraction sorbent in cleaning-up and pre-concentrating aflatoxins from nut extracts. They both recorded high extraction efficiencies (EEs) of > 97 % in selectively extracting the aflatoxins (AFB1, AFB2, AFG1 and AFG2). High reproducibility marked by the low %RSDs of < 1% and low LODs of ≤ 0.02 ng/g were calculated in all cases. The LODs were within the monitoring requirements of the European Commission. The results were validated with a peanut butter certified reference material. The chlorophyll MIP on the other hand selectively removed chlorophyll that would otherwise interfere during pesticide residue analysis (PRA) from > 0.6 to <0.09 Au in green plants extracts. The extracted chlorophyll was removed to far below the level of ≥ 0.399 Au that is usually associated with interference during PRA. Furthermore, the MIP demonstrated better selectivity by removing only chlorophyll (> 99%) in the presence of planar pesticides than the currently employed graphitized carbon black (GCB) that removed both the chlorophyll (> 88%) and planar pesticides (> 89%). For the interfering cholic acid during drug residue analysis, cholic acid MIP electrospun nanofibers demonstrated to be more sensitive and possessing higher loading capacity than the MIP particles. 100% cholic acid was removed by the nanofibers from standard solutions relative to 80% by the particles. This showed that the nanofibers have better performance than the micro particles and as such have potential to replace the particle based SPE sorbents that are currently in use. All the templates were optimally removed from the prepared MIPs by employing a novel pressurized hot water extraction template removal method that was used for the first time in this thesis. The method employed only water, an environmentally friendly solvent to remove templates to ≥ 99.6% with template residual bleeding of ≤ 0.02%.

- Description: Many Active Pharmaceutical Ingredients (API) such as the antiviral agent famciclovir (FCV) are required for paediatric treatment but are not commercially available in age-appropriate dosage forms. It is common practice to prepare oral liquid dosage forms using commercially available tablets, capsules or powdered API and then dispersing or dissolving the crushed and/or powdered materials in a vehicle that the patient can swallow. Vehicles that are commonly used for this purpose include methylcellulose, syrup or combinations of these carriers where possible or commercially available suspending agents such as Ora-Sweet®, if available, can be used. However, several critical factors are overlooked when manufacturing extemporaneous formulations including, but not limited to, physical and chemical properties of the API, excipients, compatibility, stability and bioavailability issues. A stability-indicating High Performance Liquid Chromatography (HPLC) method for the analysis of FCV was developed and validated according to the International Conference on Harmonization (ICH) guidelines. The method is sensitive, selective, precise, accurate and linear over the concentration range 2-120 μg/ml. The stability of 25 mg/ml FCV formulations was assessed in vehicles manufactured from syrup simplex, hydroxypropyl methylcellulose (HPMC), Ora-Sweet® and an aqueous buffer (pH 6) following storage at 25 °C/60% RH and 40 °C/75% RH over six (6) to eight (8) weeks. The shelf life of the products was calculated as the longest period of storage for approximately 90% of the added FCV to be recovered. Formulations were manufactured using syrup simplex or HPMC with methylparaben and propylparaben individually or in combination and with sodium metabisulphite, ascorbic acid or citric acid as antioxidants. The resultant products were subject to quality control analysis for API content, viscosity, pH and appearance and the resultant data were subject to statistical analysis. The degradation rates were calculated for each product and a degradation profile plotted. The degradation rates of FCV in extemporaneous formulations were compared to those of FCV manufactured using a commercially available suspending agent and a buffered vehicle. FCV undergoes major degradation in the presence of sucrose, as observed for formulations in which the vehicle was syrup and Ora-Sweet®. FCV was found to be most stable when dissolved/dispersed in an HPMC vehicle incorporating sodium metabisulphite and a combination of parabens. The formulation that exhibited the maximum stability was manufactured using an aqueous solution buffered to pH 6. Due to the enhanced stability of FCV when added to a buffered vehicle a formulation in which an HPMC vehicle buffered to pH 6 with sodium metabisulphite, methylparaben and propylparaben was selected for optimisation using a Central Composite Design approach (CCD). In this way it was possible to establish a relationship between input variables such as pH, % w/v HPMC, % w/v antioxidant and % w/v preservative and the responses selected for monitoring by means of response surface modelling. A quadratic model was found to be the most appropriate to describe the relationship between input and output variables. Thirty batches of product were randomly manufactured according to the CCD and analysed to establish the stability in respect of viscosity, pH and the amount of FCV remaining following storage and the data were fitted to models using Design-Expert® software. A correlation between input variables and the responses was best described by a quadratic polynomial model. Analysis of Variance indicated that the response surface models were significant (P-value < 0.0001). The pH to which a FCV formulation was buffered was the most significant factor to effect the % drug content and the ultimate pH of the formulation, while the % w/v HPMC had the most significant effect on the viscosity of the product. The optimum composition for the manufacture of an oral liquid FCV formulation was predicted using the optimisation function of the Design-Expert® software. A low % error of prediction was established, indicating that the model is robust and that RSM is an appropriate formulation optimisation tool as it has a high prognostic ability. A liquid FCV formulation was developed, optimised and found to be suitable for its intended purpose. However further optimisation is required in respect of colourants, sweeteners and/or flavourants. The approach followed is useful in ensuring the development of quality products and can be applied in future.

- Description: The tourism sector in Zanzibar Tanzania has emerged strongly in the past 15 years, helping the development of other Industries that support it. As a result, Industries such as telecommunication, IT, transport and hospitality have also emerged recently. It is, however, speculated that organizations in the tourism sector in Zanzibar generally lack the effective performance that is required of them to compete in the contemporary complex and turbulent market environment. This research thus set out to explore and diagnose the organizational effectiveness of the accommodation units of the tourism sector in Zanzibar. The research had specific objectives of diagnosing and finding the gap between the current and the optimal organizational performance in two particular units of accommodation as well as determining the factors affecting organizational performance in these units. The study furthermore set out to recommend implementation of suitable intervention activities to improve organizational performance in the units analyzed. In order to achieve the above objectives the research deployed an action research strategy with the Weisbord’s six box model as a framework to diagnose two five star grade accommodation units in Zanzibar. A qualitative method was used to collect data. Key findings of the research are briefly presented below: - The service output of the accommodation units analyzed was not very consistent and fell short of the expectation of their customers. This showed a gap in terms of the organizations’ performance. - Factors affecting organizational effectiveness were found to be mainly in the Purpose and Rewards functions of the organizations. - The specific areas in the Purpose function that appeared to have substantial problems were: -- Goals of the organization were not clearly stated -- Employees did not understand the purpose of the organization -- Employees were not involved in deciding their work unit goals -- Employees were not in agreement with the goals of their work units. -- Employees did not understand priorities of the organization The specific areas in the Reward function that appeared to have substantial problems were: -- The pay scale and benefits of the organization did not treat employees equitably. -- Employees felt that the salary they received was not commensurate with the jobs they performed. -- Not all tasks to be accomplished were associated with incentives. Following the diagnostics findings above, the research suggested the following intervention activities that could possibly help to address the above mentioned problems: - A Management by Objectives (MBO) process was suggested to redress the problems indicated in the Purpose function. This would help to set clearly agreed goals at all levels of the organizations. Employees and resources would then be directed towards achieving these goals that would enable the organizations to perform more effectively. - Revision of the current reward system was suggested to redress the problems indicated in the Reward function. The reward system should be implemented in a manner that creates a feeling of both internal as well as external (market) equity among employees. Furthermore, rewards should be linked to performance in order to direct behaviour and motivation among employees. The performance based reward system can also help to achieve the MBO process proposed above since rewards will be designated for achievement of individual, departmental and finally organizational objectives, thus increasing organizational effectiveness.

- Description: The small business sector in today‘s world is considered seriously by researchers, scholars, policy-makers and governments as an important answer in addressing problems of unemployment, poverty alleviation, and redistribution of wealth. Promoting and encouraging the development of the small business sector is without any doubt a key factor for economic growth. However, this sector faced a high rate of businesses failure due to the many challenges among them, for example, the lack of marketing strategy and implementation in the conduct of the business. Several researches show the important role of marketing in a business but unfortunately it is still not a strong component in many organisations especially within the small business sector.For this reason the aim of this study was to investigate the difficulties experienced by small business managers in marketing their businesses. Taking the aim of this study into consideration, the primary objectives were to firstly look at the practice of marketing in small businesses and secondly to identify the difficulties of marketing experienced by small business managers.The literature study provided a brief overview of the small business sector, followed by a presentation of the practice of marketing in an organisation especially within small business enterprises. Moreover a discussion of the difficulties experienced by small business managers in marketing their businesses was also addressed through the literature review. The literature classified those difficulties into two types; (a)internal factors (lack of marketing planning and strategy, cost of marketing, lack of marketing expertise, perception of marketing) and (b) external factors (lack of knowledge of the market environment).The empirical study was conducted to evaluate the practice of marketing in small businesses and to see what marketing difficulties were experienced by small business owners and/or managers. Data were collected by means of a survey, using a questionnaire. Respondents were identified using the snowball sampling technique through the database of the Nelson Mandela Bay Chamber of Commerce. The data gathered from 67 usable questionnaires were analysed and interpreted. The results of the empirical study revealed that the biggest problems experienced by small business managers in the sample were the heavy cost of marketing followed by the lack of marketing expertise and finally the lack of marketing segmentation strategy. This study contributes to the enhancement of the literature on small business marketing with a focus on the difficulties experienced by owners and/or managers in implementing marketing. As a result this study presents recommendations and suggestions to assist managers in marketing their businesses.

- Description: The small business sector in today‘s world is considered seriously by researchers, scholars, policy-makers and governments as an important answer in addressing problems of unemployment, poverty alleviation, and redistribution of wealth. Promoting and encouraging the development of the small business sector is without any doubt a key factor for economic growth. However, this sector faced a high rate of businesses failure due to the many challenges among them, for example, the lack of marketing strategy and implementation in the conduct of the business. Several researches show the important role of marketing in a business but unfortunately it is still not a strong component in many organisations especially within the small business sector.For this reason the aim of this study was to investigate the difficulties experienced by small business managers in marketing their businesses. Taking the aim of this study into consideration, the primary objectives were to firstly look at the practice of marketing in small businesses and secondly to identify the difficulties of marketing experienced by small business managers.The literature study provided a brief overview of the small business sector, followed by a presentation of the practice of marketing in an organisation especially within small business enterprises. Moreover a discussion of the difficulties experienced by small business managers in marketing their businesses was also addressed through the literature review. The literature classified those difficulties into two types; (a)internal factors (lack of marketing planning and strategy, cost of marketing, lack of marketing expertise, perception of marketing) and (b) external factors (lack of knowledge of the market environment).The empirical study was conducted to evaluate the practice of marketing in small businesses and to see what marketing difficulties were experienced by small business owners and/or managers.

- Description: Small and Medium Enterprises (SMEs) significantly contribute to the growth of the economy and the employment sector. However, it is indicated that SMEs lack access to the financial products and services that are critical to their growth. Therefore, the primary objective of this study was to investigate the difficulties experienced by small businesses in accessing finance. An online questionnaire survey was considered an appropriate measurement method for this study. The targeted population of the study included all small businesses operating in the Nelson Mandela Bay Metropole. Thus, some 208 companies were identified as part of the study sampling frame. A total number of 66 questionnaires were returned out of the 208 targeted companies - giving a response rate of 29 percent. The quantitative data were processed using a STATISTICA program, leading to appropriate descriptive statistical analyses, including frequencies, means, medians and standard deviations. In order to obtain a better understanding of the difficulties experienced by small businesses in accessing finance, hypotheses were also formulated and a t-test was used to establish the statistical significance of certain demographic variables and company characteristics regarding the problems experienced by small businesses in accessing finance. The results of the empirical study revealed that the major difficulties faced by small businesses in their access to finance were the lack of collateral and security, the high cost of borrowing interest and the delay in feedback from the financial institutions. Further, by testing the hypotheses, it was also revealed that the ethnic group of the applicant, the total years of business experience of the applicant and the annual turnover of the business have an impact on the access to finance. Based on the relevant literature study and the empirical results, recommendations were made in order to address the identified problems. However, the unavailability of an exhaustive small business database in the Nelson Mandela Bay Metropole did not allow the research to draw on a larger representative sample. Thus, this limitation has impeded in-depth statistical analysis that would have allowed the research to obtain more accurate findings. Further studies could investigate the reasons why in many cases financial institutions reject the funding of small businesses.

- Description: In South Africa, it is evident that women are uniformed of their essential human rights, especially their inheritance and succession rights, including protection of such rights. Human rights are international norms that protect individuals everywhere from the states’ political, legal and social abuse. Human rights are entitlements which human beings have in order to enhance their human condition. They are the fundamental entitlements or minimum standards to be met for individual so that they live with dignity. This study focused on discrimination of women under customary law in South Africa with reference to inheritance and succession. The study validated the findings of other researchers on the impact of cultural practices on women’s rights to inheritance and succession. In addition the findings revealed that efforts t eliminate traditional practices, should foremost come from men and from communities that hold such destructive attitudes towards women. The outcomes and recommendations of this study would assist the government and other institutions to adopt effective measures to empower women and especially educate them so that they can assert and defend their human rights

Dreams, sexuality and fantasy: a psychoanalytic reading of K. Sello Duiker’s novels

- Description: The primary aim of this thesis is to provide a text-based literary study exploring the characters and themes created by K. Sello Duiker in the three novels, Thirteen Cents, The Quiet Violence of Dreams and The Hidden Star. Duiker’s work is significant because it highlights prominent societal challenges prevalent in post-apartheid society. By analysing Duiker’s novels one acquires a better understanding of this author, an understanding of the world that contributed to the creation of his texts and his contribution to South African literature. Insight into Duiker’s fictional world allows for a careful investigation of the prominent societal issues prevalent in Duiker’s work - a world riddled with violence, issues of sexuality and psychological distress. For this purpose this thesis is premised on the notion that underpinning K. Sello Duiker’s oeuvre is a central focus on dreams, sexuality and fantasy. Logically, therefore, the main focus of the study is specifically on the inner working of the characters’ minds and how they deal/ or are unable to cope with contemporary social concerns, often resulting in psychological turmoil and dysfunctionality. For this reason, prominent themes examined in this study are the interpretation of dreams, an exploration of sexuality and an examination of fantasy in the three novels. Psychoanalytic literary theory, with the main focus being specifically on the theories presented by Sigmund Freud is used as an analytic tool to read Duiker’s texts. Psychoanalytic theory is arguably the most appropriate for analysing Duiker’s novels as it allows one to investigate the characters’ psyches and the psychological effect of societal influences on these characters. In addition, one is also able to examine how the characters are able/ unable to deal with the trauma caused by the contemporary issues in society – issues of violence, sexuality and psychological distress. Thus, one is able to grasp an overall understanding of the characters’ behaviour and actions. Furthermore, the characters’ experiences are based on the behaviour and incidents of real people, people suffering from psychological dysfunctionality, sexuality issues and identity crisis. The first chapter discusses post-apartheid literature, and provides a brief background on Duiker, his works and his conception as a writer. Chapter two provides an overview of psychoanalytic theory and on the relevant theories of Sigmund Freud. Chapter three offers a reading of Thirteen Cents, a novel that pays particular attention to the lives of children living on the streets of Cape Town. In the next chapter The Quiet Violence of Dreams is examined with a special focus on Duiker’s experimentation with form in the construction of this novel. Aspects pertaining to sexuality and dreams are also examined. Chapter five pays particular attention to magical realism and fantasy in The Hidden Star.

- Description: The study explores drug abuse by learners in selected Grahamstown high schools. The study`s main concern is that drug abuse by learners is on the rise but yet there is less research on the drugs which are being used and the factors which motivate the learners to use such drugs. There are several drug abuse prevention strategies which are being implemented but yet they seem not to be very effective. It is in this frame of reference that this study saw it vital to focus on drug abuse by high school learners in Grahamstown. The study aims to identify the most commonly abused drugs by learners in the high schools of Grahamstown and the reasons why they use these drugs. The study made use of the mixed method research that is making use of both qualitative and quantitative research. The questionnaire was the instrument of data collection in quantitative data and interviews for the qualitative data. The packages which were used for the analysis of data include the Statistical Analysis System (SAS) V8 which was used to provide descriptive analysis and correlations. The findings of the study establish that the commonly abused drugs by learners are: alcohol with 58%, followed by cigarettes 22%, hookah-pipe 9%, dagga 7%. The main reasons why learners use drugs are: peer pressure, role models, availability, environment, and curiosity. Differences in drug use between male and female learners were noted. Twenty-five percent of the male learners and 16% of the female learners reported to be using drugs. In the view of these results, the researcher recommends that a comprehensive drug abuse prevention framework be formulated which focuses on preventing drug abuse at individual, family and community levels.

- Description: Since 1994, the educational landscape in South Africa has been subjected to on-going policy changes. The national Curriculum and Assessment Policy Statement (CAPS) which has been promulgated recently, is the third version of a post-apartheid national school curriculum. Teachers, in particular, fulfil critical roles as change agents during a process of educational transformation, as they need to facilitate the change by implementing the new national school curriculum. This study aimed to ascertain teacher experiences of continuous curriculum change, by focusing in particular on the views of selected FET teachers. Focus group interviews were conducted with teachers employed at secondary schools in an urban township in the Eastern Cape. The data revealed that the teachers‟ responses could be categorised into four broad themes, namely CAPS itself, the learners in relation to CAPS, the teacher in relation to CAPS and the Department of Education in relation to CAPS. Despite several frustrations and uncertainties, it was clear that the teachers wanted to assume agency as they expressed a commitment towards change and a willingness to implement CAPS to the best of their ability. This study however concludes that the FET teachers who participated struggled to assume full agency, due to restrictive and disabling conditions which are mostly beyond their control.

- Description: The problem of school under-performance as defined by the level of pass rates of learners in the matric examinations has been a point of educational debate in South Africa for a number of years, especially after the attainment of democracy. In the Eastern Cape, Matric Intervention Strategies (MIS) have been used to address the problem. The aim of this study was to investigate educator perceptions of the impact of the MIS on selected under-performing high schools in the Queenstown District.Two case study schools classified as consistent under-performers participated in the study. Data was collected through in-depth interviews of key educators in these schools. There were five main findings. First, educators felt that Departmental intervention strategies had not made any significant improvement in addressing underperformance in the two case study schools. Second, participants saw underperformance by schools as caused by a myriad of factors which include those related to leadership and management at school and district levels and educator and learner factors, as well as teacher union interference. They did not see MIS as being able to address the causes simultaneously. Third, the implementation of the (MIS) at school level was poorly monitored by the Departmental officials. It was reported that under-performing schools were hardly visited and supported by the subject advisors and (MIO)s. Fourth, educators perceived the role of subject advisors to be limited to CASS moderation as they did not provide any developmental support to educators experiencing content gaps. Finally, educators saw the MIS as a money making scheme for certain educators and district officials. They claimed this was linked to corrupt practices during the appointment of tutors. The teachers did not have confidence in the appointment procedures used by the district for tutors.It can be concluded that the Matric Intervention Strategies in the two schools arenot likely to achieve the intended results as long as educators do not think thatthe strategies are addressing the problems they face. Another conclusion is that the Matric Intervention Strategies are seen as ‘quick fix’ responses to what arereally deep-seated and systemic problems in education. Given the findings of this study, it is recommended that the impact of Matric Intervention Strategies be the focus of a survey research for which a probability sample must be drawn that can generate findings that are generalisable across the participating target population. For the delivery of the MIS it is recommended that the weaknesses identified by educators of the two schools be further investigated so that new implementation plans can be developed.

- Description: The development and implementation of policy guidelines remains a contentious issue. Over the past few years, difficulty still exists in implementing the Department of Education (DoE) 1999, National Education Policy Act, 1996 (No. 27 of 1996): National Policy on HIV/AIDS for learners and educators in public schools, and students and educators in further education and training institutions [here after referred to as DoE HIV/AIDS policy (1999)], while at the same time trying to transform the entire education system. This research explored the perceptions of educators in the Port Elizabeth District regarding the implementation of DoE HIV/AIDS (1999) policy guidelines. A secondary objective was to provide a reflection of how the implementation of guidelines on HIV/AIDS interventions within the schools of the Port Elizabeth District either conformed to or deviated from the guidelines outlined in the DoE HIV/AIDS policy (1999). The study was executed within the paradigm of qualitative research and employed an exploratory, descriptive and contextual design. The researcher conducted a pilot study to enhance the trustworthiness of the study. Purposive sampling was employed to recruit research participants, consisting of 12 educators from 10 schools in the Port Elizabeth District where HIV/AIDS interventions were being implemented. Data was gathered through semi-structured interviewing and analysed using Tesch’s (1990) in De Vos, Strydom, Fouché & Delport (2005:340-341) framework for analysis of qualitative data. Guba’s model (in Krefting, 1991) was used to ensure the trustworthiness of the study. Three themes emerged from the results of the in-depth semi-structured interviews: (1) Educators’ views on the DoE HIV/AIDS policy (1999) guidelines and its implementation (2) Gaps or shortcomings in implementation of the DoE HIV/AIDS policy (1999) and (3) Educator suggestions’ to inform implementation of the DoE HIV/AIDS policy (1999) in schools. The results from the study indicate that there is inconsistency in the policy implementation approach employed by DoE district level representatives and there is a need for knowledge and capacity development at district and school level. The value of the study is outlined as well as recommendations.

- Description: The development and implementation of policy guidelines remains a contentious issue. Over the past few years, difficulty still exists in implementing the Department of Education (DoE) 1999, National Education Policy Act, 1996 (No. 27 of 1996): National Policy on HIV/AIDS for learners and educators in public schools, and students and educators in further education and training institutions [here after referred to as DoE HIV/AIDS policy (1999)], while at the same time trying to transform the entire education system. This research explored the perceptions of educators in the Port Elizabeth District regarding the implementation of DoE HIV/AIDS (1999) policy guidelines. A secondary objective was to provide a reflection of how the implementation of guidelines on HIV/AIDS interventions within the schools of the Port Elizabeth District either conformed to or deviated from the guidelines outlined in the DoE HIV/AIDS policy (1999). The study was executed within the paradigm of qualitative research and employed an exploratory, descriptive and contextual design. The researcher conducted a pilot study to enhance the trustworthiness of the study. Purposive sampling was employed to recruit research participants, consisting of 12 educators from 10 schools in the Port Elizabeth District where HIV/AIDS interventions were being implemented. Data was gathered through semi-structured interviewing and analysed using Tesch’s (1990) in De Vos, Strydom, Fouché & Delport (2005:340-341) framework for analysis of qualitative data. Guba’s model (in Krefting, 1991) was used to ensure the trustworthiness of the study. Three themes emerged from the results of the in-depth semi-structured interviews: (1) Educators’ views on the DoE HIV/AIDS policy (1999) guidelines and its implementation (2) Gaps or shortcomings in implementation of the DoE HIV/AIDS policy (1999) and (3) Educator suggestions’ to inform implementation of the DoE HIV/AIDS policy (1999) in schools. The results from the study indicate that there is inconsistency in the policy implementation approach employed by DoE district level representatives and there is a need for knowledge and capacity development at district and school level. The value of the study is outlined as well as recommendations.

- Description: One of the essential sectors that needed a drastic change in the post apartheid era in South Africa, was the education system or policy of the country. The government had a responsibility of combining together the nineteen different Departments of Education into which the schools were fragmented. It is in the interest of the country that, out of the eleven official languages of the country, learners should at least be fluent in two languages namely, the learner‟s mother language and any official language which will be treated as an additional language, thus, promoting additive bilingualism. This is on line with the country‟s constitution which has granted equal status to the eleven languages. That resulted in the formulation of two very imperative policies pertaining to schools; 1) The South African Schools Act (SASA) of 1996 which repeal all discriminatory policies of apartheid. On the issue of language the SASA placed the responsibility of choosing the school subjects to the School Governing Bodies (SGB) and 2) The Language-in- Education Policy (LiEP) of 1997 which is based on the recognition that South Africa is multilingual, and promotes learning of more than one official language. In an attempt to accomplish the constitutional obligation, and establish uniformity or equality in education, Curriculum 2005 which was later revised and known as the Revised National Statement and later revised and known as the NATIONAL Curriculum Statement, with the Outcomes Based Education as its approach, was introduced. The study investigated the experiences of educators with the implementation of NCS EFAL in Grade 11 in the Fort Beaufort Education District. English First Additional Language is used by the majority of schools as the Language of Learning and Teaching (LoLT). The study is located in the interpretive paradigm which sought to explore people‟s experiences and their views. Qualitative research approach was adopted in the study with the intentions of finding as much detail as possible on the experiences of educators with the implementation of NCS EFAL in the Grade 11 classrooms. Six EFAL educators in the Fort Beaufort Education District in the Nkonkobe Municipality were purposely selected for the study. Semi structured interviews consisting of precisely defined questions that were pre-prepared, yet at the same time permitted the EFAL educators to answer beyond what the researcher enquired, were also employed in the study. The results pointed out that all EFAL educators interviewed were qualified teachers and had specialized in English teaching. In addition, the study revealed that in the Fort Beaufort Education District, there were two categories of EFAL educators who were trained for the implementation of NCS EFAL; those who only received one week departmental workshop and those who on top of the one week departmental workshop, received a two year training in Advanced Certificate In Education (ACE) English Language Teaching (ELT) from a Higher Education. The dissimilarity between the two groups manifested in their respective schools between the educators and their Heads of Departments (HOD) who happen to have little knowledge of the implementation of the curriculum. It became evident that the group of educators who were trained in ACE ELT were more familiar with the requirements of the NCS EFAL. The other group which was not conversant with the NCS EFAL policies decided to maintain their old teaching methods. Key recommendations of the study: Policy makers should clarify terminology to be understood by all educators, the Department of Education should take full responsibility of retraining educators to ensure uniformity in training through the in-service trainings yearly.

- Description: The researcher, who is also an educator, a School Management Team member and a union official, observed that conflict among educators at schools was a cause of concern. This situation prompted the researcher to explore how school leaders and educators perceived conflict among educators at school in order to determine the perceived possible causes of conflict, the perceived possible consequences of conflict, how conflict was currently dealt with and the perceptions regarding appropriate measures to address the handling of conflict. The research was underpinned by the interpretive paradigm and followed a case study approach that involved three primary schools residing in close proximity to one another in the Northern Areas of Port Elizabeth, South Africa. Data was collected from educators and school leaders ranging from Post Level One educators to principals and covering educators from the Foundation Phase, Intermediate Phase and Senior Phase. Data was gathered by making use of an open-ended questionnaire, semi-structured personal interviews and semi-structured focus group interviews. The findings revealed that the research participants mostly viewed conflict negatively and associated it (conflict) with disagreements, misunderstandings, verbal and non-verbal fighting, and diverse views or opinions. The possible causes as identified by the participants were categorised into data-based conflict, relationship conflict, structural conflict, interest-based conflict and needs-based conflict. Data-based conflict related to issues concerned with communication, a lack of transparency and consultation, and the spreading of gossip and untruths. Relationship conflict pertained to favouritism, not valuing the opinions of others, and a lack of respect or tolerance. Structural conflict, as highlighted by the participants, were linked to issues of management and leadership, workload allocations and time tabling, punctuality and time issues and the role and responsibilities of employees. Value-based conflict was ascribed to different beliefs and viewpoints of people and differences in valuing guidance from others. Interest-based conflict was closely connected to appointments and limited possibilities around promotion posts as well as to issues with resources. Needs-based conflict focused on individuals‟ self-esteem needs and people‟s need for power and (or) status. Conflict was also perceived as having both positive and negative consequences. Positive aspects related to improved relationships, better understanding, change and improved attitudes and the development of personal growth. Negative aspects of conflict were associated with the manifestation of defiant attitudes and intolerance, poor cooperation, the formation of groups and cliques, poor morale and work ethic, poor health and stress, absenteeism and negative effects on teaching and the learners. Regarding the handling of conflict, the findings highlighted the perception that conflict is mostly avoided and (or) inadequately handled and when it was dealt with, it was done unprofessionally and inappropriately. The findings also pertained to suggestions in dealing with conflict in an appropriate manner. Here, the following important practical ways or aspects of handling conflict were suggested, namely ensuring that aggrieved parties were provided with opportunities to raise their issues, listening with serious intent, applying confidentiality and professionalism, openness and transparency, provision of fair hearings and treatment, the utilisation of policies and procedures, the value of conflict management training and the inclusion of external intervention in resolving conflict. Various outcomes were suggested by the findings. These were linked to striving towards a win-win situation, respect and understanding for all, compromise and agreement and satisfying all parties with agreements reached. The promotion of third party intervention was emphasised, with participants highlighting the characteristics that these third parties had to reflect and the procedures which they had to follow when attempting to resolve conflicts. Recommendations are also provided. In terms of these recommendations drafted, this study concludes that the recommendations can be grouped related to professional development opportunities and policies and procedures. Finally, in exploring educators‟ perceptions of conflict in three Northern Areas primary schools in Port Elizabeth, the researcher gained valuable insights into conflict among educators at schools, which could benefit educators (teachers, SMT‟s and principals) and education in general.

- Description: Bast fibrous renewable materials, as commercial crops for the manufacture of textile based and other products, have been used for thousands of years to satisfy certain human needs, such as for shelter, clothing, source of energy and tools, and to sustain the livelihood of many communities in countries, such as in Asia, Europe and Africa. Concern for the environment has led to a number of global initiatives that favour the use of natural fibres. It is forecast that the global fibre demand by 2050 will be 130 million tonnes, which the cotton and synthetic fibre production will not be able to meet. Other than the environmental concerns, the renewed global interest in natural fibres, such as flax and hemp, forms part of a strategy to satisfy the fibre demand. South Africa, notwithstanding the fact that the flax and hemp industries have long been established for thousands of years in Europe, Asia and Egypt (Africa), has no history of the breeding, growing, processing and production of these cash crops. The renewed global interest in these crops has also stimulated interest from South Africa with respect to the development of a flax and hemp fibre industry so as to address some of the socio-economic challenges confronting the country today in its attempts to bring about real development in the rural areas through the cultivation and complete beneficiation of these fibre crops. In this regard, the relevant stakeholders, namely government, research councils, tertiary education institutions, farmers and communities worked together to investigate whether South Africa has the agronomic and climatic conditions, technical expertise as well as the necessary processing and production infrastructure to support the development of a local flax and hemp agro-industry. The purpose of this study was firstly to evaluate the performance of EU flax and hemp cultivars grown under different agronomic conditions in South Africa, and their effect on straw biomass yield, fibre yield and total fibre yield per hectare as well as associated fibre properties, and secondly to undertake mechanical fibre modification trials aimed at producing flax and hemp fibres with fibre diameters close to those of cotton. The minimum fibre diameter targeted being 20μm. In accordance with the project objectives and work plan, selected dew retted flax and hemp straw samples from the various planting sites selected by the Agriculture Research Council – Institute for Industrial Crops, representing all the agronomic conditions under investigation, were taken to the CSIR for fibre extraction and testing. A relatively inexpensive and easy to operate Russian designed and manufactured machine, the CMT-200M breaker-cum-scutcher, was used for fibre extraction and the resultant extracted fibre bundles were further refined, using a steel comb, to obtain optimal fibre separation before their physical and chemical properties were evaluated. Results obtained in this research study proved that the climatic and agronomic conditions in South Africa were suitable for the cultivation of flax and hemp, notwithstanding the fact that the fibre yields achieved for hemp were lower than the minimum criteria of 23 percent, and that for flax only just exceeded the 25 percent minimum. The lack of local technical expertise on the growing and retting of flax and hemp, contributed to the low fibre yields. The planting parameters which were found to produce good results for the cultivation of hemp were the October planting date, using a row spacing of between 12.5 to 25 cm, with a seeding density of between 80 – 100kg, and the application of 50 – 100kg nitrogen fertiliser. The use of extra artificial lighting and herbicide treatment did not appear to beneficially improve the hemp fibre yields. Similar considerations for flax cultivation in the Southern Cape region, particularly Oudtshoorn and Outeniqua, indicated that May to July planting dates, using inter-row spacing of 25cm and sowing density of 63kg seed.haˉ¹, produced a fibre yield and total fibre yield per hectare above the minimum values of 25 percent and 0,8 tonnes per hectare, respectively, quoted in the literature.

- Description: The objective of this study was to compare the nutrient status of full scavenging and semi-scavenging village chicken production systems. The semi-scavenging chickens were given broiler finisher mash between 14-24 weeks of age, whilst the full scavenging relied on natural foraging. The study also sought to compare the quality of meat from chickens from the two systems. After slaughtering the chickens, the crop contents were physically separated and analysed for chemical composition. Meat pH and colour were measured on the breast muscle of individual carcasses and a consumer sensory evaluation was also done on the breast muscle. The mean crop content weights per day were significantly higher in full scavenging chickens (±16.7g/day biomass) than in semi-scavenging chickens (±9.14g/day). Dry matter, calcium, and phosphorus levels were higher in the crop contents of the full than in the semi-scavenging chickens but crude protein, crude fibre and metabolisable energy were higher in the latter system. Semi-scavenging (1.3 ± 0.05kg) carcasses were heavier (P<0.05) than full scavenging ones (1.0 ± 0.06kg). The ultimate pH (24h) (pHu) of meat from full scavenging chickens (6.0 ± 0.03) was higher (P<0.05) than that of meat from the semi-scavenging chickens (5.7 ± 0.04). Meat from the full scavenging chickens had higher L* values (60 ± 1.2) than meat from the semi-scavenging chickens (47 ± 0.8). The a* value of meat of full scavenging chickens was significantly (P<0.05) less (4 ± 0.4) than that of meat from semi-scavenging chickens (15 ± 1.3). There was a significant positive (0.60) correlation between pHu and L* of meat from village chickens across rearing systems. The semi-scavenging system meat had better sensory attributes than the meat from the full scavenging system. Female consumers scored the typical flavour of village chicken meat across rearing systems higher (P< 0.05) than male consumers. The Shona consumers scored the meat higher (P< 0.05) than the Xhosa, Zulu, Ndebele and other tribes for initial juiciness, first bite impression and muscle fibre and tenderness of the chicken across rearing systems. Consumers scored of the meat from the semi-scavenging system higher (P<0.05) on initial juiciness (4.3 ± 0.20), first bite impression (4.2 ± 0.197), muscle fibre tenderness (4.5 ± 0.217) than meat from the full scavenging chickens. There were positive correlations (0.46) between aroma intensity and overall flavour intensity across both rearing systems. The semi-scavenging system produced better carcass characteristics, lighter (L*) meat and more consumer acceptable meat than full scavenging chickens. Therefore the full scavenging rearing system had better nutrient composition in its scavenging feed resource base, although the semi-scavenging systems produced chickens with better carcass, meat pH, colour and sensory characteristics than the full scavenging chickens.

Therefore the full scavenging rearing system had better nutrient composition in its scavenging feed resource base, although the semi-scavenging systems produced chickens with better carcass, meat pH, colour and sensory characteristics than the full scavenging chickens.

- Description: The effect of stage of lactation on milk yield, somatic cell counts, mineral and fatty acid profiles in pasture-based Friesian, Jersey and Friesian × Jersey cows was investigated. Twenty Friesian, twenty Jersey and twenty Friesian × Jersey cows were randomly selected from a dairy herd. A total of 202 milk samples were collected and analysed in three stages of lactation. Genotypic differences were observed in milk yield and fat content. Friesian cows produced the highest yield and lowest fat content whereas the opposite was true for Jersey cows (P<0.01). No significant differences were observed in SCC in the different genotypes, but SCC levels were higher in mid and late lactation (P<0.001). There was no effect (P<0.005) of genotype and stage of lactation interaction on Ca, P, Mg, Na, Mn and Bo concentration. Jersey cows had the least concentration of Fe and Cu in all stages of lactation. Strong positive correlations were observed among Ca and P, Mg and Zn. Aluminium had a strong positive relationship with Bo, Fe, Mn and Zn (P<0.001). Generally, SCC had a weak positive relationship with macro elements but a significant negative relationship with microelements. Yield levels were negatively correlated with Mg, Na, Al, Mn and SCC. Pasture ALA, SFA, n-3, n-6/n-3 and PUFA/MUFA concentration did not differ across the study period. Linoleic acid was highest in the second phase which coincides with mid lactation in cows (P<0.001). Highest moisture content coincided with the least fat free dry matter content in early lactation (P<0.001). Significantly high fat content was observed in late lactation than in early lactation. Highest butyric, caproic, linoleic, n-6 and PUFA were observed for Friesian cows. All other fatty acids ratios were not significantly different among different genotypes. Highest CLA, ALA, LA, SFA, PUFA, n-6, and n-3 and atherogenicity index were observed in early lactation whereas desaturase activity indices were highest in late lactation. Strong positive correlations were observed among milk vaccenic, ALA, LA and CLA concentrations. Inverse relationships were observed between SFA and long chain fatty acids. It can be concluded, it may be of advantage to consume milk from early stage of lactation poses a lower risk to coronary diseases and are much safer to consume.

- Description: This study examined the existing levels of effectiveness and efficiency in local government with the application of performance management systems in the provision of municipal services. The provision of district-wide water services in Cacadu District Municipality in the Province of the Eastern Cape, South Africa is used for particular reference. Local government reforms after 1994 led to the creation of the district municipality (which groups together a number of local municipalities) to drive district-wide services provision, the introduction of systematic services provision standards and performance management as part of management reforms in municipalities. The problem for the research deals with how the Cacadu District Council and the councils of the local municipalities within the district are collaborating in using performance management systems, what effects this could have on programmes and services provision and how communication of performance information would improve service provision. Conceptual and practical difficulties encountered in effective and efficient utilisation and some obstacles that contribute to impeding progress in the use of performance management systems in municipalities were analysed. The qualitative research included a review of documents from the public administration and management literature; discourse analysis of interviews with municipal councilors and appointed officials, community members and provincial managers. The document review included a review of municipal documents that incorporated performance management or described development and use of performance management systems. It also included the legal frameworks and statutory requirements for municipal government and administration. All the responding municipal councils within the Cacadu District Municipality reported using performance management over the past five years yet little empirical evidence explains usage for district-wide programmes and services provision. Research shows that a comprehensive performance management approach to programmes and services has a more effective and efficient impact on service improvement than utilisation of personnnel appraisal (Ammons and Rivenbark, 2005). Despite the expected benefits, personnel performance appraisal is often flawed and the need exists in the district municipal model to develop and utilise performance management systems that validly assess the work performance of personnel (Hindo, 2010). Performance management system utilisation in decision making management is more related to the long-term benefits of effectiveness and efficiency than personnel appraisal for performance rewards and reporting. To overcome and address a situation of managing performance without a performance management system the study proposes a programme performance measurement and management system which incorporates information on management inputs, programme-specific data and citizens' feedback for outcomes and impact of the service. The suggested design for district-wide and specific municipal services provision elicit and provide relevant and appropriate performance information for management, decision-making and accountability to community. The effectiveness of the proposed system is to provide information for decision-making, long-term planning, strategic management and accountability reporting. The proposal is built on the exisiting method and thus efficient in the utilisation of resources. This has implications both for the theory of Public Administration and Management and the practical application of performamce management in public institutions. The study explicity provides a Public Administration perspective on management in a multi-municipal district context with different authorities. The study contributes to the theory of administrative policy and management context of the municipality with special attention to functions for which different authorities are responsible and the role of a performance system for better insught into managing overlapping authority, gaps and duplications. A central purpose of public management research is to theorise and influence practice. The practical utilisation of the proposed method is intended to assist managers and politicians with better understanding of a sustainable performance management system.

- Description: The aim of the study was to explore, describe and compare the impact of a 12-week intervention on selected physical fitness variables in sub-elite martial artists. The experimental group (expG) participated in a combination of alternating dojo and gymnasium-based resistance training, each bi-weekly, with the comparison group (comG) exclusively undergoing four conventional dojo training sessions weekly. The variables measured included; anthropometric measures (height, body mass and percentage body fat); functional core muscular endurance; hamstring flexibility; upper body muscular strength and endurance; lower body muscle strength; and static balance. A quasi-experimental research design was employed, with pre - and post - test assessments after a 12 week intervention period. Purposive and snowball sampling techniques were employed from existing dojo’s in Port Elizabeth, with a randomised allocation of participants into two groups. The gymnasium-based training programme was designed according to the national conditioning and strength association (NCSA) principles of resistance training. The identified variables were tested at a 95% level of probability (p < 0.05). Similar trends in performance improvement were evident for both the expG and compG in of the majority of the selected physical fitness variables. One-way, two-sample and independent t-tests analysis found no statistical significant intra- group or inter-group differences in any of the selected dependant variables for both groups. Thus, the supplemental resistance training programme was not superior to that of the conventional dojo training programme in improving aforementioned variables. Despite the lack of statistical significance, these results indicate that a structured and supervised resistance training programme in a gymnasium may serve as an alternative method of intervention for improving physical fitness in sub-elite mixed martial artists. The resistance training programme should be specifically adapted according to the individual practitioner’s strengths and weaknesses, as well as to the type of martial art being practised.
