- Description: The Namibian government through the Ministry of Education seeks for teachers to meet the demands and rise to the challenges of the post-independence basic education system. Therefore the University of Namibia Education Faculty must ensure through the training of student teachers for both lower, upper primary and secondary school level that these demands are met. Research shows that one of the major challenges in teacher training programs, specifically in the mathematics education programmes, lies with the student teachers’ difficulties in dealing with various topics in mathematics, particularly fractions. The teaching of fractions is a challenging area at primary level and lays the foundation for understanding different topics in upper grades such as algebra, ratio and proportion, statistics and probability, to mention just a few. This study focused on an exploration of teaching fractions by five student teachers during their teaching practice.The main purpose was to gain an understanding of the experiences of the level 5-7 student teachers with regard to their practice of fraction teaching; their experience of the mathematics education course with respect to the teaching of fractions; and their prior experience related to fractions and fraction teaching at Grade 6 level. The findings from this research showed that student teachers viewed mathematics, specifically fractions, as just about doing calculations, doing drill and practice as in this way learners’ understanding of fractions is enhanced. The importance of using rules and procedures was emphasized as paving the way to mastering fractions. The data analysis also revealed that student teachers employed different teaching approaches when they considered learners’ prior knowledge. However, they misinterpreted the learner-centred approach in terms of group work and class discussion in their teaching of fractions. The data also revealed that some student teachers had an understanding of fractions as they managed to redirect their learners from applying some fraction misconceptions. The findings further showed that due to lack of understanding most of the participants experienced fear and anxiety in their fraction teaching; attempted an approach then reverted to old practices used in schools; taught fractions as symbolic representations where no meaning was involved; used incorrect terminologies such as ‘1 over 4’ or ‘1 out of 4’ instead of a ‘quarter’ or ‘one-fourth’. It is further revealed that the some student teachers viewed a fraction as a pair of two different whole numbers and can be broken apart. The findings of this study yielded one main implication for the teaching of mathematics: that the teacher training programs, specifically for mathematics teachers, must take into consideration the weaknesses and strengths of the student teachers shown in this study to properly train and prepare them to become effective mathematics teachers.

- Description: The primary purpose of the study was to investigate the extent to which the Nkonkobe Local Municipality is able to meet its obligations in terms of the LGTAS - specifically as a rural municipality. Further to investigate what impact, if any, the Report on the State of Local Government in South Africa has had on the municipality. The study moved from the premise that municipalities are different, and that a rural municipality’s response to service delivery and the LGTAS, should be understood in the context of additional challenges, because of its remote locality. The study therefore is based on the assumption that the Nkonkobe Local Municipality has not been able to fully meet the objectives, as they are contained in the LGTAS that was approved by Cabinet in December 2009. The study proposed to give a background of the origin of municipalities and evolution and transformation of Developmental Local Government in South Africa. The in-depth literature review was undertaken on Developmental Local Government to achieve the objective of the study. Local Government Turnaround Strategy analysis with reference to Nkonkobe Local Municipality is also presented to test the proposed hypotheses. The empirical survey and research methodology used in the study is described and explained in-depths and followed by data collection in a form of a questionnaire. The research findings of the empirical survey are then analysed and reported in statistical form. In the final chapter; recommendations are presented based on the empirical survey findings through the respondent’s inputs in the questionnaire. Recommendations are also presented on how Nkonkobe Local Municipality can improve its business to achieve the objectives of LGTAS.

- Description: The Northern Areas of Port Elizabeth are mostly comprised of the so called “Coloured” community and is vibrant in tradition and musical activities. Community music in the form of marching bands, brigade bands, wind bands and brass bands form a central part of the music activities in this area. The non-availability of music education in schools combined with the multitude of social challenges creates a cultural and moral vacuum. Children are not exposed to the finer arts and music in particular and without these bands and groups probably never will. This study will explore five community bands/groups and the role they play in the lives of people and especially the children and the youth. The impact and influence music has on the social upliftment of under-privileged children in this area has never been studied. The study shows the big impact these bands/groups have on the children and the communities they serve and highlights the dedication and good work of those band managers working with these groups. The study concludes with a proposal that an art/music centre be established in the Northern Areas of Port Elizabeth.

- Description: This study took place at a private high school in the Kavango region with my 32 grade 10B learners as the research participants. Its objective was to investigate how the grade 10 learners make sense of concepts on refraction of light through exploring their cultural beliefs/everyday experiences about the rainbow. This research study was essentially triggered by my own classroom experience of teaching the topic on refraction of light. In order to achieve the goal of this research, a qualitative case study located within an interpretive paradigm was adopted. To gather data I used multiple data gathering techniques such as brainstorming session, learners conducting interviews in the community, practical activities and focus group interviews. This resulted in descriptive data that qualified to be analyzed in a qualitative way. The themes that emerged from the generated data were coded using upper letter cases and various colours. A methodological triangulation was employed by using multiple data generation techniques. Member checking during focus group interviews also ensured validity in this case study. The findings of this study revealed that the use of learners’ cultural beliefs/everyday experiences can be used to enhance learner engagement, meaning making and conceptual development during the science lessons. In addition, the ways in which practical activities are designed and presented to learners in the science classroom determine learners’ participation and conceptual attainment. Therefore, based on my research findings, I recommend that teachers need to be trained to be able to elicit and integrate learners’ cultural beliefs/everyday experiences in conjunction with hands-on practical activities which focus on conceptual development during their science lessons. However, although this study had many benefits, it also showed that it is not easy to close the gap between learners’ prior everyday knowledge and school science. This warrants further research.

- Description: The research area of this work is online threat awareness within an information security context. The research was carried out on secondary school learners at boarding schools in Grahamstown. The participating learners were in Grades 8 to 12. The goals of the research included determining the actual levels of awareness, the difference between these and self-perceived levels of the participants, the assessment of risk in terms of online behaviour, and the determination of any gender differences in the answers provided by the respondents. A review of relevant literature and similar studies was carried out, and data was collected from the participating schools via an online questionnaire. This data was analysed and discussed within the frameworks of awareness of threats, online privacy social media, sexting, cyberbullying and password habits. The concepts of information security and online privacy are present throughout these discussion chapters, providing the themes for linking the discussion points together. The results of this research show that the respondents have a high level of risk. This is due to the gaps identified in actual awareness and perception, as well as the exhibition of online behaviour patterns that are considered high risk. A strong need for the construction and adoption of threat awareness programmes by these and other schools is identified, as are areas of particular need for inclusion in such programmes. Some gender differences are present, but not to the extent that, there is as significant difference between male and female respondents in terms of overall awareness, knowledge and behaviour.

- Description: The participation of communities and community organizations in Municipal governance is set in terms of the law as a mechanism to deepen democracy. Municipalities are required to develop a culture of governance that complements representative democracy with community participation. However the participation of communities in local governance has not translated to the strengthening of governance and the deepening of democracy as municipalities have not done enough to involve communities in municipal affaires. Lack of human resources, and financial capacity have been cited as some of the reasons that beset municipalities and undermine citizen participation. Municipalities have taken steps to encourage community participation and these include establishment of structures to enable participation, however without the guidance and financial support of the municipalities these structures are not able to perform their functions. In spite of all the efforts made by municipalities to encourage participation, a culture of community participation has not yet taken root in local government. While the legislative framework provides for communities to participate, practice shows that the implementation of legislation is complex and requires dedicated capacities within the councils to be effective. This can be achieved when municipalities develop their own community participation policies which address their special circumstances, which must be reviewed on a regular basis. Unless communities are empowered with knowledge on the available participation mechanisms, the dream of a culture of participation will remain just that, a dream. Thus civic education coupled with capacity building of officials will assist in ensuring the development of a culture of participation. Council must also develop mechanisms to evaluate the effectiveness of community participation processes and procedures, to avoid a one size fits all approach. It is imperative that councils as the legislative arm of municipalities must lead the process and not leave everything to the executive arm.

- Description: Microbiota are present in large numbers and as a diverse population within the gastrointestinal tract. There are approximately 400 different species of microbiota which may be beneficial, harmful or both, but each play an important role in the regulation and modulation of the hosts’ bowel processes (McOrist et al. 2008; Dethlefsen et al. 2008). Many of these colon microbiota allow for saccharolytic fermentation of non-digestible dietary fibres and carbohydrates into by-products and intermediates, followed by a subsequent conversion into short chain fatty acids (SCFAs) (mainly n-butyric acid, propionic acid and acetic acid) each of which play an important role in maintaining colon homeostasis (Topping & Clifton 2001). A balance of ‘good’ microbiota (e.g., Bacteroides spp./ Bifidobacteria spp.) and ‘bad’ microbiota (e.g., Veilonellae) and the optimal production of various SCFAs within the gut could possibly allow for proper functioning of the large intestine and assist in decreasing the onset of various colonic disorders such as Irritable Bowel Syndrome (IBS). The sample group for the study consists of male and female patients, with an average age of 40 to 50 years old, whom of which have been diagnosed with either constipation IBS (C-IBS) or diarrhoea IBS (D-IBS) via the Rome III criteria system for IBS diagnosis. DNA and SCFA extractions were optimised for human stool, colonic fluid and tissue biopsy sample obtained from the aforementioned patients. Optimization steps allowed for starting material with high analysis integrity. Different methods of microbiota analysis, such as ARISA, were investigated; however, real-time qPCR was selected as the best method to identify and quantify specific microbiota. Extracted SCFAs were separated via gas chromatography and identified and quantified via Mass Spectrometry. Significant changes in microbial content and SCFA profiles were found to be associated with healthy and IBS patients. Results obtained would however be influenced by external factors typical of clinical studies of this nature. This study allows for opportunities for future research into understanding IBS.

- Description: black owners by white colonialists. Even though whites made up less than 20% of the nation‟s population, they took more than 80% of the agriculturally productive land and drove the original owners to the unproductive reserves where they were cramped and could not practice agriculture at all. Various acts such as the Black Land Act of 1913, Development Trust Act of 1936 and the Native Laws Amendment Act of 1937 were introduced which further frustrated the displaced black population thereby plunging it deeper and deeper into poverty. The main objective behind the introduction of these acts was to restrain the black population from earning livelihoods through agriculture thus forcing them to offer their labour to white farmers for low wages just to earn some form of livelihood. Such unfair practices and distribution of land prompted the first democratically elected government of South Africa to embark on a drive to redistribute the nation‟s land equitably amongst its citizens to foster national reconciliation, stimulate economic growth and compensate those that were forced out or lost their land during the apartheid era. This initiative was called the Land Reform Programme (LRP) and was implemented with three prongs namely (i) land redistribution; (ii) restitution; and (iii) land tenure. Among the beneficiaries of the LRP were farmers from a community called Marselle in Kenton-on-sea. In addition to getting land for farming purposes, the Marselle farmers also obtained financial support from the government‟s Land Bank to help them kick-start their farming activities. However, in spite of such interventions, they have struggled to turn their activities into sustainable livelihood sources. One most likely cause for this is the lack of farming knowledge and skills needed to make them more efficient and productive. This study was thus geared towards evaluating the knowledge and skills gap in Marselle which, when addressed, could make the Marselle farmers more productive. Its focus was limited to the 32 livestock and 8 chicory farmers that are recognized members of their respective projects. Focus was limited only to these farmers since the next phase of this study will involve building their capacity based on the skills gaps identified through this study. The findings showed that the two projects benefited at least 130 individuals belonging to the farming households, with 67.5% of these households headed by males. The age of these farmers was equally shared at 40% each between those above 65 years and those that only went as far as fourth grade. No one went to tertiary at all. At least 75% of the investigated farmers were unemployed and 42% of this population was pensioners. In terms of income though, 64.98% of it was from external sources. The Masakhane Silime (Chicory) project was implemented to generate income and provide job opportunities for the locals but neither of these objectives had been met at the time the data for this study was collected due to various challenges like lack of funds and infrastructure to enhance productivity. Just like the chicory project, the livestock project had its own objectives, namely; to remove animals from the residential areas, provide the animals with a safe place, reduce road accidents and also to provide a livelihood source for local farmers. Due to overgrazing the pastures, lack of proper camps and other challenges, some effort still needs to be put to achieve these objectives. Even though the livestock project was formed with these objectives in mind, the farmers themselves reared livestock either for personal consumption, selling, ritual purposes, store of wealth or all these combined. Regarding technical skills, livestock farmers were found to rely mostly on indigenous knowledge sources to attain farming knowledge. Only animal healthcare knowledge was popular to more than half the respondents. This was said to be due to the focus group meetings held on the farm every other Wednesday to share information with local extension officers. In spite of these information sharing events, livestock farmers identified training on how to feed; market; handle; and treat their livestock as key intervention knowledge areas. Attendance to these focus group meetings was limited to livestock farmers only. Various socio-economic factors were also found to have some form of influence on the acquisition of livestock knowledge. Education was the most dominant factor, with a significant association with the farmers‟ feeding (p=0.033); animal healthcare (P=0.038); marketing (p=0.009); veld management (p=0.036); and cattle slaughtering (p=0.027) knowledge. Other variables most influential include the gender and age of the household head. The former was significant at 95% confidence level for farmers‟ feeding knowledge (p=0.021); animal healthcare (p=0.039); marketing (p=0.043); livestock housing and handling (p=0.023); veld management (p=0.018); and cattle slaughtering (p=0.043). The dominance of males in acquiring these skills could be explained by the fact that the majority of the livestock project members were males. The majority of the few female members became members by default after the passing on of their husbands but their participation in the project was done through other project members who looked after their animals on their behalf. The number of farming years also had some positive and significant influence on other knowledge areas such as feeding (p=0.021) and livestock housing and handling (p=0.013). The logic supporting this association is that farmers tend to accumulate new and more skills the longer they stay in the same enterprise. In addition, most of the interviewed farmers were farm labourers prior to relocating to Marselle hence they acquired the necessary knowledge long before the project started. Concerning the chicory project, its members also relied heavily on indigenous knowledge sources for farming knowledge. Soil preparation (24.1%); planting (20.7%); land care (24.1%); and mechanical weed control (48.3%) were the knowledge areas lacked by more than half the respondents. The farmers identified land preparation (75%); communication skills (25%); marketing (100%); financial management (62%); and harvesting (88%) as the key crucial intervention areas they needed prioritized. As a study meant to inform the capacity building phase of the Land Bank project, this study identified the existing skills gaps in the two projects implemented in Forest Hill. When implementing the Capacity Building (CB) phase, various socio-economic factors will have to be considered. For example, the proposed intervention should not discriminate against anyone on the grounds of gender or physical abilities. The skills introduced should also be simple enough to be accepted and acquired even by the illiterate, especially when one considers the high illiteracy levels amongst the respondents. Efforts should also be made to create partnerships with the right organizations or groups of people so that they provide the required expertise and resources for the benefit of the farmers as and when required.

- Description: black owners by white colonialists. Even though whites made up less than 20% of the nation‟s population, they took more than 80% of the agriculturally productive land and drove the original owners to the unproductive reserves where they were cramped and could not practice agriculture at all. Various acts such as the Black Land Act of 1913, Development Trust Act of 1936 and the Native Laws Amendment Act of 1937 were introduced which further frustrated the displaced black population thereby plunging it deeper and deeper into poverty. The main objective behind the introduction of these acts was to restrain the black population from earning livelihoods through agriculture thus forcing them to offer their labour to white farmers for low wages just to earn some form of livelihood. Such unfair practices and distribution of land prompted the first democratically elected government of South Africa to embark on a drive to redistribute the nation‟s land equitably amongst its citizens to foster national reconciliation, stimulate economic growth and compensate those that were forced out or lost their land during the apartheid era. This initiative was called the Land Reform Programme (LRP) and was implemented with three prongs namely (i) land redistribution; (ii) restitution; and (iii) land tenure. Among the beneficiaries of the LRP were farmers from a community called Marselle in Kenton-on-sea. In addition to getting land for farming purposes, the Marselle farmers also obtained financial support from the government‟s Land Bank to help them kick-start their farming activities. However, in spite of such interventions, they have struggled to turn their activities into sustainable livelihood sources. One most likely cause for this is the lack of farming knowledge and skills needed to make them more efficient and productive. This study was thus geared towards evaluating the knowledge and skills gap in Marselle which, when addressed, could make the Marselle farmers more productive.

- Description: This research sought to investigate the sources and type of tasks used in the teaching of trigonometry in Zambia’s secondary schools, and to investigate the criteria used and decisions made by teachers in their selection and implementation of tasks. The study was conducted in three different school types located in high cost, medium cost and low cost respectively. One participant was chosen from each of the different categories of schools. The research was located within an interpretive paradigm. Data were collected through semi-structured interviews, lesson observations and document analysis which include: lesson plans for five consecutive days, pupils’ activity books and three textbooks predominantly used by the teachers. Document analysis was informed by the task analysis guide and essential themes which were used to tease out teachers’ task practice with regard to criteria used and decisions made in the selection and implementation of tasks. Essential themes that were qualitatively established were validated and explicated by the qualitative analysis. The findings of the study indicate that teachers picked tasks from prescribed textbooks. The study further suggests that teachers selected a mix of low and high level tasks, procedures without connections and procedures with connections tasks to be specific. There were no memorisations and doing mathematics tasks. Their choice of tasks was based on the purpose for which the task was intended. Some tasks were selected for the purpose of practicing the procedures and skills, other tasks for the promotion conceptual development. Most of high level tasks decline to low level tasks during implementation. The findings also indicate that teachers selected and implemented a variety of tasks and concepts. Furthermore, teachers presented tasks in various forms of representations and in a variety of ways. However, the results of this study could not be generalized because of the small sample involved. The results presented reflect the views and task practices of the target group. A possibility for future study would be to consider a large population, drawn across the country.

- Description: The shopping centre has evolved into an integral part of modern day society. New generations especially are unable to imagine a world without shopping centres. In 2008 a world wide economic down turn emphasized the competition to attract a buying market to shopping centres, some centres thrived and some centres struggled. The need to understand what creates these different responses to highly competitive scenarios is discussed in this study, with particular attention given to the tenant mix that exists in different shopping centres. Criteria that determine an optimum tenant mix are examined and the constraining factors are discussed. A literature review of shopping centres is discussed and the evolution of the shopping centre to our current day understanding of the term shopping centre is examined. Accepted definitions and categorisations of shopping centres along with a brief history of the shopping centre, as revealed by the literature, is presented. To create a tenant mix the body of tenants needs to be divided into sub- categories and various ways to achieve this are examined. The objectives of this study are to determine what strategic approaches to managing the tenant mix exists in the literature and what factors determine the formulation of this mix. Furthermore the study examines to what extent these or other strategic approaches are used in practice and finally makes recommendations to promote the optimum tenant mix in shopping centres. A literature review was conducted to determine what the theory reveals about the shopping centre industry. This was followed by an empirical survey conducted in the Port Elizabeth area of the Nelson Mandela Metropole. Finally the findings and theory were compared to make conclusions and suggest recommendation to achieve synergy in shopping centres through a optimum tenant mix.

- Description: This study is concerned with the constructions of the Tanzanian nation in the press. It has confined its focus, first, to the coverage from 2005 to 2011 on Union Day that marks the Union between Tanganyika and Zanzibar and the formation of the United Republic of Tanzania and, second, to two prominent Tanzanian newspapers, namely the state-owned Daily News, and the privately-owned The Citizen on Union Day. As the Union remains a contentious issue, the relevance of this research relates to the press’s considerable power to shape understandings and influence attitudes. The study works within a broad cultural and media studies framework and is informed by a constructionist approach to representation and to culture, and to nation in particular. It also draws of journalistic theories of agenda-setting and the normative roles of the press to probe the agendas set by the press on Union Day and to interrogate how the two newspapers construct and frame the Union of Tanganyika and Zanzibar as nation. The research responds to the question: ‘How has the Tanganyika-Zanzibar Union been represented in The Citizen and Daily News newspapers from 2005 to 2011?’ It employs quantitative and qualitative (thematic) content analysis to investigate the coverage in the editorials and feature articles of The Citizen and Daily News newspapers on Union Day (26 April) of 2005 to 2011. This study finds that the government-owned newspaper, Daily News, publishes more articles related to Union on Union Day than the privately-owned, The Citizen and collaborates more determinedly with the state in the process of constructing the nation. However, both newspapers adopt a collaborative role consistent with the development journalism tradition that endorses an informal partnership between media and the state in the process of development (Christians et al, 2009:201). Both publications tend to emphasise the hegemonic ideology pertaining to Union while giving limited attention to challenges to such constructions. While both newspapers do identify certain problems of the Union and thus exercise a monitorial role to varying extents, it is apparent that the press in Tanzania tends to be largely acritical, perhaps attributable to a long period under single party rule

- Description: Lightning as a natural phenomenon is shallowly presented in the Namibian curriculum documents such as the syllabus and textbooks. This gap in curriculum triggered my interest to investigate whether learners’ meaning-making in static electricity was enabled or constrained by elicitation and integration of their cultural beliefs and experiences about lightning and by their practical activities. This study was conducted with my grade 8 learners at the school where I am currently teaching. The school is located in a rural area in Ohangwena region in Northern Namibia. The study is situated within an interpretive paradigm. Within the interpretive paradigm, a qualitative case study approach was adopted. I considered this methodological orientation appropriate in this study as it allowed me to use the following data gathering methods: document analysis, brainstorming, discussions and presentations, semi-structured interview, focus group interview, observation and an assessment test. Multiple methods to gather data were used for triangulation and validation purposes. For data analysis purposes, the data sets were colour-coded to derive themes and analytical statements. Ethical considerations were also taken seriously in this study and all participants gave consent. An analysis of data revealed that there is no learning objective or basic competence in the Namibian Physical Science syllabus for grade 8-10 that requires learners to bring in their cultural beliefs and experiences, in particular, about lightning. Yet the study revealed that learners possess a lot of prior everyday scientific and non-scientific knowledge and experiences about lightning that they had acquired from their communities. Also, mobilization of learners' everyday knowledge and experiences about lightning enabled learner engagement during the science lessons. Likewise, engaging learners in practical activities in static electricity helped them to make meaning of scientific concepts. Based on my research findings, I therefore, recommend that learners' prior everyday knowledge and experiences about lightning should be incorporated during teaching and learning of the topic on static electricity.

- Description: The study examined the use of multiple representations such as the real world, written symbols, spoken symbols, diagrams and manipulatives by learners to promote the learning of percentages and fractions through social interaction. This investigation was carried out through a teaching and learning programme which was developed and implemented by me, the researcher. The effect of the implemented programme was the main focus of the research. The qualitative study was oriented in the interpretive paradigm – a paradigm that seeks to understand the meaning attached to human actions. Twenty learners participated in the implementation of the programme and 9 learners were selected for focus group interviews. The purpose of the interviews was to explore learners' understanding and feelings about the use of multiple representations in the learning of percentages and fractions through social interactions. The other tools employed in this study were pre-and-post diagnostic tests, observations, learners' work and a journal. The pre-test was used to determine learners' prior knowledge for the program design and implementation, while the post-test and learners' work were used to analyze the effect of the programme. Observations were used to investigate how multiple representations promoted or did not promote the learning of percentages and fractions. The teacher's journal was to record and reflect on any relevant information gathered on each lesson observed. The data shows that the effective use of multiple representations helped learners learn the concept of percentages and fractions better. Learners were able to look at representations in useful ways; multiple representations made some aspects of the concept clear; and multiple representations enabled learners to correct errors. Through the interaction between the teacher and learners, the following was found: all the learners changed words to change focus; learners made links between multiple representations; the learners deepened their concepts of percentages and fractions; learners could convert between fractions using multiple representations; learners could work out percentages of a quantity; and learners could express one quantity as a percentage of another. Furthermore, through the interaction between learners and learners all learners could identify more equivalent fractions of an initial fraction which was given to them; and they could increase and decrease a quantity by a given percentage. On the basis of this research, it can be concluded that the programme promoted the learning of percentages and fractions through three effective methodologies. The first methodology consisted of the effective use of multiple representations; the second methodology concerned the interaction between the teacher and learner during the learning process and the last methodology related to the interaction between the learners - interactions that were not strongly mediated by the teacher. I would recommend that teachers use these three effective approaches when teaching percentages and fractions to promote the learning of the concepts.

The qualitative study was oriented in the interpretive paradigm – a paradigm that seeks to understand the meaning attached to human actions. Twenty learners participated in the implementation of the programme and 9 learners were selected for focus group interviews. The purpose of the interviews was to explore learners' understanding and feelings about the use of multiple representations in the learning of percentages and fractions through social interactions. The other tools employed in this study were pre-and-post diagnostic tests, observations, learners' work and a journal. The pre-test was used to determine learners' prior knowledge for the program design and implementation, while the post-test and learners' work were used to analyze the effect of the programme. Observations were used to investigate how multiple representations promoted or did not promote the learning of percentages and fractions. The teacher's journal was to record and reflect on any relevant information gathered on each lesson observed. The data shows that the effective use of multiple representations helped learners learn the concept of percentages and fractions better. Learners were able to look at representations in useful ways; multiple representations made some aspects of the concept clear; and multiple representations enabled learners to correct errors. Through the interaction between the teacher and learners, the following was found: all the learners changed words to change focus; learners made links between multiple representations; the learners deepened their concepts of percentages and fractions; learners could convert between fractions using multiple representations; learners could work out percentages of a quantity; and learners could express one quantity as a percentage of another. Furthermore, through the interaction between learners and learners all learners could identify more equivalent fractions of an initial fraction which was given to them; and they could increase and decrease a quantity by a given percentage. On the basis of this research, it can be concluded that the programme promoted the learning of percentages and fractions through three effective methodologies. The first methodology consisted of the effective use of multiple representations; the second methodology concerned the interaction between the teacher and learner during the learning process and the last methodology related to the interaction between the learners - interactions that were not strongly mediated by the teacher. I would recommend that teachers use these three effective approaches when teaching percentages and fractions to promote the learning of the concepts.

- Description: Decentralization of governance is one of the many reforms that has been undertaken by the Department of Education in the Republic of South Africa since the attainment of democracy in 1994. The concept of decentralisation originates from the belief that the state alone cannot control schools, but should share its power with other stakeholders, particularly those closer to the school, on a partnership basis (Marishane, 1999:78). The South African Schools Act (SASA) No 84 of 1996 mandates the establishment of democratic structures of school governance in all schools (RSA, 1996a, section 16). According to the South African Schools Act No 84 of 1996, School Governing Bodies have been mandated to be responsible for the recommendation of teachers for appointment through interviews. This study was conducted in the Libode District in the Eastern Cape. Libode is composed of rural villages which are characterised by poverty, a high rate of unemployment and illiteracy. Many schools in the Libode district of education are experiencing problems emanating from the recruitment of teachers carried out by the SGBs. Interviews conducted by the SGBs are more often than not nullified and the selection and interview processes have to be repeated. They (SGBs) fail to defend their recommendations with valid facts when challenged by union representatives or by candidates themselves. The major concern of this study is to investigate the stakeholders' perceptions of the involvement of school governing bodies in the appointment of teachers in Libode district. A qualitative approach was employed for this research study. Purposive sampling was used for sampling the schools from which interviewees were selected. There were 14 respondents in the sample. Three (3) school principals , three teachers, three (3) teacher candidates, one SADTU teacher, one NAPTOSA teacher, two (2) SGB parents from the parent component and two (2) circuit managers were interviewed. The case study research design was employed to explore the perceptions of the stakeholders regarding teacher appointments. This research employed three data collection techniques, namely semi-structured interviews, documents analysis and observations. The main findings of this study reveal that the involvement, or participation, of the SGBs (parent components) in the recruitment of teachers is the source of conflict and disputes. The SGBs lack capacity, capacity to draft criteria for shortlisting qualified teachers, and capacity to conduct interviews properly and fairly. Findings suggest that problems still exist around SGBs' knowledge of Policies and Acts that enshrine procedures pertaining to teacher recruitment. In conclusion, from the findings, it appears premature for the system to mandate this professional function of teacher recruitment to the office of the SGBs.

- Description: Detpak South Africa is a subsidiary paper and board company of Mpact Limited, formally known as Mondi Packaging South Africa. The Mpact group of companies operates across 31 sites and employs more than 3 700 employees. Detpak South Africa specializes in three respective niche markets: international fast food packaging, industrial packaging and disposables packaging. The primary objective of this study is to propose an operational model for improving customer satisfaction levels within the disposables market for Detpak South Africa. Further, Detpak’s competitive position with respect to customer satisfaction was assessed and an empirical assessment was conducted to identify imperative attributes impacting on overall customer satisfaction. It is noted from marketing journals that providing a quality product at the right price no longer suffices as an adequate value proposition. Numerous authors have noted that there is no longer a difference between a goods market and a service market, in its purest form, and that manufacturers of goods must embrace the principles of service marketing to develop a competitive advantage within the market. A quantitative research was conducted to obtain data. The measuring instrument used to obtain data was a self-administered questionnaire. A total of 84 questionnaires were distributed nationally across South Africa. From the 84 questionnaires a total of 62 questionnaires were obtained from respondents, from which a final sample of n=59 was considered for capturing. Three questionnaires were excluded from the sample due to response error of non-completion. Correlation coefficient analysis was used to calculate the relationships between independent and dependant variables. It was found that all customer satisfaction attributes, listed below, had a positive relationship to overall customer satisfaction: Customer value; Product quality; Price; Communication; Reliability; Responsiveness; Customer service; Sales support. The hypothesized relationship between overall customer satisfaction and customer loyalty was measured and confirmed to be strongly positive. It can be concluded that a positive movement in overall customer satisfaction will be accompanied by a similarly positive movement in customer loyalty. Furthermore, through secondary review it was noted that the retention of existing customers costs much less and is more profitable than the acquisition of new business. The results presented within this study indicate a strong market position for Detpak South Africa in terms of product quality compared against competitive activity, which means a competitive advantage in the market for the company and which will assist in attaining its strategic objectives. The results also identified a number of customer satisfaction attributes which Detpak South Africa could improve to allow them to establish a firm position in the market through the overall improvement of customer satisfaction levels. Finally, an operational model integrating the important concepts identified within the literature study was proposed to assist Detpak South Africa in enhancing levels of perceived customer satisfaction. The model integrates the important business philosophies of customer relations, best practices, continuous improvement and, finally, customer satisfaction attributes.

While its focus is on Kenya, it evaluates the normative quality of protection and standards offered by regional instruments against the existing, as well emerging, parameters for implementation at the domestic level. In this regard, the article examines the propriety of Kenya’s newly promulgated law on internal displacement in providing for protection for the development induced IDPs, the implementation programme that it establishes and its prospects for furthering the vision of the UN Guiding Principles on Internally Displaced and other regional instruments.

- Description: There are some fundamental underlying requirements that need to be in place for a system of precedent to operate. Of these I wish to isolate two that are germane to this note. The first is that court decisions (especially those in which a written judgment is handed down) need to be clearly reasoned and logically articulated to be understandable, effective and to have value in a system of precedent that finds its ultimate lodestar in the rule of law. There is no constitutional or statutory requirement that a court in all cases must furnish reasons, or even written reasons, for its decision But the practice of doing so, the Constitutional Court has said, supports the rule of law, ensuring that judicial decision-making does not occur in a manner that is arbitrary, and ensures that judges may be held accountable for their decisions. The second requirement is a technical rule – the rule of majority: if the case is heard by a full bench, and where differing opinions are handed down by the judges hearing the case, the ratio decidendi can only be identified from those judges whose reasoning is in the majority.

- Description: Records from community-based coastal management initiatives indicate that local communities who are key actors in activities that aim at safeguarding the health status of terrestrial and marine ecosystems face a lot of challenges associated with adapting andapplying indicators that are scientifically abstracted and methodologically too reified, given varying social, contextual and technical conditions prevailing amongst them. This paper brings into view possible challenges of adapting and applying scientific indicators in community-based monitoring of mangrove ecosystem and suggests a new approach that may lead to development of indicators which are less reified, more congruent to users (coastal communities) and likely to attract a wider social learning in the mangroverestoration context. It also sets a bridge for scientific institutions (including universities), tounderstand various social, cultural and contextual needs that determine epistemological access between them and local communities, which need to be addressed prior to engaging targetcommunities in participatory monitoring programmes.The paper attempts to analyse learning at the interface of knowledge that scientific institutions produce and the potential knowledge that exists in local context (traditional ecological knowledge) for purposes of widening and improving knowledge sharing and safeguarding the health status of mangrove species and fisheries that use them as key habitats. The paper stems from a study which employs processes of abstraction and experiential learning techniques such as Experiential Learning Intervention Workshop carried out in 2012,to unlock knowledge that local communities have, as an input for underlabouring existing scientific indicators in the eastern coast of Tanzania.It brings into view the need to consider contextual realities on ground, the level of education that the participating group has, the minimum level of participation that is required, structures that govern coastal monitoring practices at local level and the need for scientific institutions to consider the knowledge that local people have as an input for enhancing or improving coastal monitoring, especially monitoring of mangrove and fishery resources. The paper finally comes up with a framework of indicators which is regarded by coastal communities as being less reified, more contextually and culturally congruent and which can easily be used in detecting environmental trends, threats, changes and conditions of mangrove and fisheries resources, and attract wider social learning processes.

- Description: A hydrokinetic coil pump (HCP) is described by its name. It is a coil pump driven by the kinetic energy in flowing water. The hydrokinetic energy is converted into mechanical energy by means of a paddle-wheel. The coil pump makes up part of the paddle-wheel and together is called a HCP. The HCP floats in a stream of flowing water while tethered to the bank. The focus of the study was to identify and analyse the factors influencing the HCP. The HCP was then optimized for rural application. Data acquisition took place through experimentation on a full scale experimental platform according to a central composite experimental design. Variables used for the experimentation included; Stream Velocity, Delivery Head, Number of Coils, Discharge, Number of Paddles, Paddle-Wheel rotational speed Overall HCP efficiencies of up to 22 percent were obtained. The efficiency would drop as the stream velocity increased. Stream velocity has been identified as the most influential factor with regards to the variables analysed by this study. The HCP is ideal for rural application. The simplicity of the design ensures reliability as well as an effective water supply solution. The HCP is ideal for slow flowing rivers and can deliver up to 1190ℓ/h to a delivery head of 5m with a stream velocity of 1.2m/s. This is sufficient to supply a small rural community with running water.

- Description: Developing countries such as South Africa have a tremendous potential for rapid and sustainable economic and social development by leveraging the benefits and advantages of Information and Communication Technology (ICT) and applying it appropriately within the local government sector. As such, the Local Government Turnaround Strategy’s (LGTAS) vision states that: Each municipality must have the necessary ICT infrastructure and connectivity; and that ICT systems must be put in place across all municipalities to accelerate service delivery, and improve efficiency and accountability. However, technology on its own cannot achieve much; it must be supported by capable people and tested processes to provide services in which the public can have confidence. Disparities, both from within the municipal sector as well as in the larger South African ICT landscape, have influenced the manner in which municipalities make use of ICT. Nevertheless, it has been observed that despite the use of ICT, there has been a lack of utilising ICT governance to enhance corporate governance in the public sector, particularly in municipalities. In this study, an analysis was made of ICT governance initiatives, as a mechanism to enhance corporate governance, with particular reference to the Nelson Mandela Bay Municipality (NMBM) in the Eastern Cape. The research itself has identified risk levels that exist as a result of the lack of ICT governance and risk management. The respondents were given an opportunity to agree or disagree with statements regarding the state of ICT provision and support, corporate governance and other elements within the institution. The researcher has formulated recommendations to solve identified problem based in the research results in ICT governance and corporate governance. While governance developments have primarily been driven by the need for transparency regarding enterprise risks and the protection of shareholder value, the pervasive use of technology has created a critical dependency on ICT that calls for a specific focus on ICT governance. ICT governance is part of corporate governance,which is the responsibility of the organisation’s top executive, to ensure that its information technology supports the goals and objectives of the organisation, through a variety of structural mechanisms, processes and mechanisms for communication. Fundamentally, ICT governance is concerned with whether ICT is delivering value and the management of ICT risks, driven by a strategic alignment between business and ICT, resources management and performance management. The corporate governance of ICT involves evaluating and directing the plans for the use of ICT to support the Institution and monitoring these. It includes the strategy and policies for using ICT within the institution. The executive authority and executive management are accountable and responsible for ensuring that the governance of ICT is implemented in the institution in line with this framework.
