  • Description: The primary motivation for this research was to examine political apathy amongst students at Nelson Mandela Metropolitan University. The secondary motivation was to question whether youth political apathy threatens the consolidation of democracy. More specifically, the purpose of the study was to critically analyze contemporary literature on the politics of young people in post apartheid South Africa, in order to identify its shortcomings and give an in-depth explanation for youth political apathy, and how it impacts democracy. The writer has employed a qualitative method. Four focus groups were arranged by the researcher at Nelson Mandela Metropolitan University. All participants of the study were Nelson Mandela Metropolitan University (NMMU) undergraduate and postgraduate black students aged 21-35. The sample of this study included fifty participants. Thus the researcher has utilized a purposive sampling technique. Participants were encouraged by the researcher to have maximum participation in the focus group deliberations. The researcher also made use of elite interviews in the study. The findings of this study suggest that political apathy amongst students at Nelson Mandela Metropolitan University does exist. Most of the participants in the focus groups indicated that young people in post-apartheid South Africa have no interest in politics.

  • Description: It has been estimated that between 3000 and 4000 plant species are used for their medicinal properties throughout South Africa, with approximately 27 million South Africans making use of traditional medicines. Of this 27 million, 3 million South Africans rely on traditional medicine as their primary source of health care. Of the 250 000 to 500 000 known plant species, very few have been investigated for their pharmacological qualities, and compounds of significant medicinal value may still remain undiscovered in many plant species. The aims of this study included investigating the antimicrobial properties of Geranium incanum and Artemisia afra, both plants traditionally used for their medicinal properties, and comparing the antimicrobial activity of the latter to that of Artemisia absinthium, as well as investigating the anticancer properties of G. incanum and A. afra, and comparing the anticancer activity of the latter to that of A. absinthium. Infusions, aqueous-, methanol- and acetone extracts of the three plants were prepared and used for anticancer and antimicrobial screening. Plant specimens used to prepare extracts for antimicrobial activity were collected and extracted over three seasons, while extracts used for anticancer screening were prepared from plants collected during the summer only. Considerable variation existed in the percentage crude extract yields obtained when different extractants were used, while the season in which the plants were harvested and extracted also appeared to play a significant role in the amount of extract obtained. The plant extracts were screened for antimicrobial activity against various strains of Candida albicans, Escherichia coli, Pseudomonas aeruginosa, Enterococcus faecalis, Staphylococcus aureus and Bacillus cereus, using an agar dilution method. G. incanum and A. afra possessed activity for C. albicans, while all three plants showed activity for S. aureus and B. cereus. Activity was largely dependent on the extraction method used. iii The 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay was used to screen for anticancer activity of the respective extracts, at varying concentrations, against MCF-7 (human breast adenocarcinoma) cells, HT-29 (human colonic adenocarcinoma) cells and HeLa (human cervical cancer) cells. All of the extracts showed cytotoxic activity in all three cell lines to varying extents, depending on the extract used and cell line screened. The acetone extract of A. afra proved to be the most effective inhibitor with the lowest IC50 (2.65 ± 1.05 μg/ml) having been shown in MCF-7 cells. A. afra and A. absinthium showed similar inhibitory patterns, with the methanol- and acetone extracts having been the most potent inhibitors of each of the respective cell lines in general. Fluorescence microscopy employing 4',6-diamidino-2-phenylindole dihydrochloride (DAPI) and propidium iodide (PI) staining indicated that the acetone extract of A. afra induces apoptosis in MCF-7 cells as apposed to necrosis, and the results were comparable to those obtained for cells exposed to cisplatin. Screening of the A. afra acetone extract for toxicity in normal human cells using the CellTiter-Blue® assay indicated the extract to be toxic to peripheral blood mononuclear cells (PBMC’s) at concentrations comparable to that for MCF-7 cells, while cell cycle analysis of MCF-7 cells exposed to the A. afra acetone extract indicated the extract’s ability to induce apoptosis comparable to that of cisplatin, with the extract exerting its activity at a point during or just prior to the S phase of the cell cycle.

  • Description: Simulation is a complex task with many research applications - chiey as a research tool, to test and evaluate hypothetical scenarios. Though many simulations execute similar operations and utilise similar data, there are few simulation frameworks or toolkits that allow researchers to rapidly develop their concepts. Those that are available to researchers are limited in scope, or use old technology that is no longer useful to modern researchers. As a result of this, many researchers build their own simulations without a framework, wasting time and resources on a system that could already cater for the majority of their simulation's requirements. In this work, a system is proposed for the creation of a scalable, dynamic-resolution network simulation framework that provides scalable scope for researchers, using modern technologies and languages. This framework should allow researchers to rapidly develop a broad range of semantically-rich simulations, without the necessity of superor grid-computers or clusters. Design and implementation are discussed and alternative network simulations are compared to the proposed framework. A series of simulations, focusing on malware, is run on an implementation of this framework, and the results are compared to expectations for the outcomes of those simulations. In conclusion, a critical review of the simulator is made, considering any extensions or shortcomings that need to be addressed.

  • Description: This study looks at aspects of the development of environmental education in South African National Parks (SANParks), in relation to the emergence of national and organisational policy frameworks. In order to put current environmental education practices into context, the study firstly looks at the historical development line of environmental education in SANParks, as well as in the broader national context. This provides a framework within which the processes of change and development can be traced in terms of social, political and economic influences on an international and national front. The study finds that the promulgation of legislation, including the Constitution, National Acts and various other policies, reflected the trends of thinking and set the pace in a democratic South Africa, which led to the emergence of more explicit processes and refined policies. Popkewitz’s finding, that education emerged in modernity, is used in the study to illustrate this tendency. It finds that these changes in South Africa resulted in the establishment of more structured environmental education processes within SANParks, and led to the expansion, diversification and strengthening of environmental education as a field of practice over time. The study traces significant processes of recontextualisation of international and national environmental education related policies according to the framework established by Bernstein (1980). These processes of recontextualisation were followed in the formulation processes of SANParks policy and strategy documents in the period from 1999 to 2005, and resulted in an official pedagogic discourse for environmental education in SANParks. The study establishes a second level of recontextualisation, that is, the official pedagogic discourse of environmental education in SANParks is recontextualised to a pedagogic discourse of reproduction. The pedagogic discourse of reproduction relates to park practices, where contextualisation within park-based programmes appears to be strong. The park-based programmes resemble a ‘curriculum in practice’, which brings us to Cornbleth’s critical curriculum approach. The study utilises this approach to explore and explain the meaning of the critical perspective taken on curriculum construction and change efforts at park implementation level (Cornbleth, 1990). The study finds that the contextualisation of park programmes and practices lead to variety in park programmes, which adds richness to environmental education programmes and activities, and further highlights the fact that environmental education practices are prolific in national parks. The study also finds that historical and contextual processes associated with specific parks strongly characterise environmental education programmes and practices in those parks, and that partnership programmes, such as the Kids in Parks programme, contribute towards, and enhance the growth of environmental education as a specialised field of practice in SANParks. The study comments on the need for environmental education practices in SANParks to be reviewed and expanded in line with the contemporary approach towards the environment as a social construct of interacting components. These components include the biophysical, social, economic and political dimensions. The study also highlights the need for the recognition and acknowledgement of the long, historical development line of environmental education in SANParks in order to build on established structures in a holistic way. The study further determines a need for strong leadership to successfully expand this specialised field of practice and encourages a participatory approach in the review and further development of this field of practice in SANParks. The study ultimately finds that environmental education in SANParks has a long and rich development profile, which has placed it in a strong position for further development. However, it concludes that there is a great need for a rejuvenated approach, which requires expert knowledge, professionalism and broad based networking approach to enable meaningful expansion within this specialised field of practice.

  • Description: The socio-economic dimension of conflicts has enjoyed increasing attention in research dealing with the dynamics of contemporary conflict. The underlying assumption of this study is that the socio-economic dimension of conflict can be hugely informative in terms of providing an understanding as to why peace agreements fail and in that sense can contribute to the resolution of conflicts if taken into account during the formulation of peace agreements. This study explores the way in which conflict theory has dealt with conflict and determines to what degree peace agreements in the Sudan have taken into consideration the socio-economic dimension of the conflict between the North and South Sudan since February 1972 to January 2005. This study proposes a number of recommendations in terms of the peace process in the Sudan with possible wider application to other future peace agreements.

  • Description: South Africa has, since 1994 undergone significant political, social and economic changes and all these changes have had an effect in most of the governmental departments. One department adversely affected in particular, is the Department of Education (DoE). The implementation of a large number of educational policies being developed at national and provincial levels to bring about radical changes, leave much to desire. That has led the researcher to be investigating Teachers’ Formative Assessment Practices in Grade 9 Technology classrooms of selected schools in the Fort Beaufort District of Education. The DoE had explored ways to better educate learners and to improve the entire school performance, hence the introduction of the new methods of assessment, to quote but one, assessment policy No. 19640 of 1998. The new assessment policy in the GET Band is a means of assessing learners in order to enhance individual growth and development; to monitor the progress of learners; and to facilitate their learning. This policy states that assessment and feedback are integral to the teaching and learning process and policy planners and practitioners must be adequately prepared to implement these policies. Assessment is the most powerful lever educators use to influence the way learners respond to teaching and behave as learners. It is crucial that appropriate and effective methods of assessment are employed to ensure effective learning. Therefore, the study examined, within the interpretive paradigm and taking a constructivist approach, experiences and concerns raised by participants concerning the implementation of formative assessment in the case. In order to investigate teachers’ perceptions and the implementation of formative assessment practices, in relation to emerging educational policies, one Grade 9 learning area – Technology - in five schools were purposefully sampled. Data from the participants were mainly collected employing qualitative methods, being in-depth interviews, observations and document studies. The main findings of the study were that participants’ (School Management Team members, teachers and learners) perceptions were not quite clear pertaining to what formative assessment is all about. They did not know how to implement it in their classes and as a result had a negative impact on them. This led to recommending that these practitioners must adequately and rigorously be re-trained in implementing the policy. The DoE ought to outsource such trainings to tertiary institution for certification purposes. In future, the DoE should, before implementing any policy, make sure facilitators know the policy, are adequately and thoroughly trained and skilled before embarking on any further training of policy practitioners.

  • Description: Digital audio network technologies are becoming more prevalent in audio related environments. Yamaha Corporation has created a digital audio network solution, named mLAN (music Local Area Network), that uses IEEE 1394 as its underlying network technology. IEEE 1394 is a digital network technology that is specifically designed for real-time multimedia data transmission. The second generation of mLAN is based on the Plural Node Architecture, where the control of audio and MIDI routings between IEEE 1394 devices is split between two node types, namely an Enabler and a Transporter. The Transporter typically resides in an IEEE 1394 device and is solely responsible for transmission and reception of audio or MIDI data. The Enabler typically resides in a workstation and exposes an abstract representation of audio or MIDI plugs on each Transporter to routing control applications. The Enabler is responsible for configuring audio and MIDI routings between plugs on different Transporters. A Hardware Abstraction Layer (HAL) within the Enabler allows it to uniformly communicate with Transporters that are created by various vendors. A plug-in mechanism is used to provide this capability. When vendors create Transporters, they also create device-specific plug-ins for the Enabler. These plug-ins are created against a Transporter HAL Application Programming Interface (API) that defines methods to access the capabilities of Transporters. An Open Generic Transporter (OGT) guideline document which models all the capabilities of Transporters has been produced. These guidelines make it possible for manufacturers to create Transporters that make use of a common plug-in, although based on different hardware architectures. The introduction of the OGT concept has revealed additional Transporter capabilities that are not incorporated in the existing Transporter HAL API. This has led to the underutilisation of OGT capabilities. The main goals of this investigation have been to improve the Enabler’s plug-in mechanism, and to incorporate the additional capabilities that have been revealed by the OGT into the Transporter HAL API. We propose a new plug-in mechanism, and a new Transporter HAL API that fully utilises both the additional capabilities revealed by the OGT and the capabilities of existing Transporters.

  • Description: The Struandale Engine Plant (SEP) was set up in 1924 and was the 16th Ford plant outside North America. The plant has since produced a variety of different components ranging from wheel hubs, to engine components such as crank shafts and cylinder blocks, to the assembly of engines. Manufacturing at this plant has predominantly been via the job-shop method, where mass production techniques were used. The RoCam programme preparation started in 1999. In 2001, SEP experienced a very steep ramp-up due to an unexpected surge in volume requirements. This forced the plant’s Human Resources team to embark on an “emergency” recruitment drive to cover the required human resources to support the programme. Due to this action being taken by the Human Resources department, the educational level of the employees was at a very basic level and had an adverse effect on productivity. The SEP operating committee made a decision in 2004 to focus on the implementation and maintenance of the Ford Production System (FPS). This initiative was important because ageing equipment needed to be maintained at predetermined intervals through continuous improvement techniques that form part of the FPS programme. If these techniques are not in place, the Overall Equipment Efficiency (OEE) suffers. This programme comprises a number of critical elements such as FTPM that requires a certain education and skill level in effort to completely comprehend the system. Evidently, education was an issue and an effort had to be made to upgrade the workforce skill’s level, specifically the team leaders. On the 30th January 2008, Ford Motor Company of Southern Africa (FMCSA) had announced plans to invest more than R1.5-billion to expand its operations in South Africa for the production of Ford's next-generation compact pick-up truck iv and Puma diesel engine. In an effort to secure and retain the Puma contract at SEP, the plant had to prove that it could compete globally; hence it had to improve OEE levels to the world-class standard. The Puma engine contract had been contracted to South America, Turkey, Thailand, and South Africa. This was a strategic move in order to retain flexibility within the supply chain i.e. if one supplier / plant cannot deliver, demand can be shifted to one of three alternative suppliers. The problem statement which will be addressed by this research is: What are the main causes for the poor Overall Equipment Efficiency level (OEE) at the Struandale Engine Plant of Ford Motor Company of Southern Africa? The Primary Objective of this research is to: Identify the main causes for the poor Overall Equipment Efficiency level (OEE) at the Struandale Engine Plant of Ford Motor Company of Southern Africa

  • Description: I embarked upon this study to investigate mathematics teachers' practices that have led to the persistence of traditional teaching methods in grade 9 mathematics classrooms in Rundu. The study was conducted from a learner-centred (L-C) perspective or reform approach in the Namibian context. It is a qualitative study oriented in the interpretive paradigm- a paradigm that seeks to understand the meanings attached to human actions. The participants involved in this study were purposively selected and they are composed of two mathematics teachers and their grade 9 learners. This study was conducted at two schools in Rundu. One is an urban school while the other one is a rural school on the outskirts of Rundu. The research tools employed in this study are questionnaires, interviews and observations. The questionnaires were used to identify and select my participants while the observations were used to investigate the participants teaching strategies. The purpose of the interviews was mainly to investigate teachers' understanding, interpretation and implementation of learner-centre education (LCE). Amongst other findings, this study reveals that inadequate teacher-training, controversial educational policies and challenges such as overcrowdedness in mathematics classrooms, lack of teaching and learning materials, lack of cooperation among mathematics teachers and learners' negative attitude towards mathematics are some of the contributing factors to the persistence of traditional teaching methods in mathematics classrooms. Moreover, the study reveals that the persistence of traditional teaching methods in mathematics classes can no longer be attributed to the lack of understanding of LCE. The teachers in this study seem to be well acquainted with the theoretical aspect of the LCE framework while the implementation aspect seems to be a concern.

  • Description: The introduction of school governing bodies provided communities with an opportunity to play a significant role in the organisation and governance of their schools. This involvement of significant stakeholders is purported to oversee that schools offer education of high quality to the learners. However, school governance is a legal responsibility, which requires the skills, knowledge and expertise to ensure that SGB members will be able to fulfil their concomitant legal duties. The aim of the study was to investigate the impact of the SGBs role in school governance in Kuyasa Secondary School, King Williams Town District. The findings revealed that the SGBs knowledge and understanding of their roles and responsibilities, and the type of training they receive have a marked effect on their functionality. There is also a need to recruit SGB members with a particular level of education, knowledge, understanding and expertise to minimise the chances of failure.

  • Description: The issue of student participation in school governance is not a new concept in Namibian schools. Student involvement dates back to the 1970's when the country's administration was under the South African apartheid regime. Back then the involvement of students in school affairs was seen by the regime as a political act and attempts by student leaders to involve themselves in educational issues were often quashed. When the country became independent student representation continued as Student Representative Councils (SRC's), later renamed Learners Representative Councils (LRCs). This study attempted to investigate the perceptions of LRCs and other stakeholders - narnely the school principals and the school board members - of the role of students in school governance. The study was conducted in three Senior Secondary Schools in the Kavango region in Namibia. The research respondents were school principals, chairpersons of the LRCs and one chairperson of a school board. The study was conducted in the interpretive paradigm employing the following three qualitative research methods interviews, observation and document analysis to collect data. Through triangulation it was possible to formulate a rich response to the research question. The study found that, although the notion of student participation in school governance was widely accepted, a number of challenges exist that hamper the effectiveness of LRCs in the schools. It was revealed that there was no national policy docunlent that outlined the roles and function of the LRCs. As a result schools had little direction about the LRCs and subsequently they were given little or no attention by the school authorities. This resulted in misunderstandings and in some cases conflict between learners and the school management. The most significant consequence of these problems was the fact that LRCs were not regarded as true role players in school governance. The study thus recommends that a national policy document that legitimates the role of students in school governance be drafted to provide direction and that schools embark on meaningful training programmes for LRC members. The study also calls for further research to address the gap in literature on this phenomenon, particularly in Namibia.

  • Description: South African School Governing Bodies play a crucial role in the governing of schools. One of the key challenges facing the School Governing Bodies is to contribute towards the creation of an atmosphere which is conducive for effective learning and teaching. This, among other ways, could be done by formulating a code of conduct for learners. The purpose of this study was to find out the role of the School Governing Body in formulating the code of conduct for learners. The subjects of the study were the parent and teacher components of the School Governing Bodies. Data collection for this study included questionnaires which were completed by parents and teachers who are members of the School Governing Bodies. Such data has been used to analyze and interpret the role played by the School Governing Bodies in formulating the code of conduct for learners. Among others, the study found that some members of the School Governing Bodies were not aware about their respective roles in the formulation of codes of conduct for learners and the policy relating to the code of conduct for learners. However, some School Governing Bodies have adopted the Provincial guidelines on the code of conduct as the code of conduct for their schools. The study recommends that the members of the School Governing Bodies should be empowered through, among others, continuous training courses relating to their respective roles in school governance.

  • Description: Many secondary schools in the Eastern Cape and else where in South African are facing a drop out crisis but a proportion of these dropouts return to school to complete their education. The kind of social experiences that dropouts have as they reenrol and reintegrate in school remains an under-research aspect in the discourse on education access. The purpose of this study was to investigate the factors that prompted dropouts to reenrol in school and the social life experiences of these learners in school. It was also to explore school leaders‟ reactions towards these experiences, and the implications for school leadership of the dropouts‟ experiences. Using qualitative methodologies, involving a sample of 15 dropouts and two school leaders, the study found multiple motives, associated with individual characteristics of dropouts and the institutional characteristics of their family and the labour market, prompting reenrolment. Institutional characteristics at the school level were not featured. Regarding social life at school, it found that while some participants had positive social experiences, which reinforced their motivation to pursue their education, others experienced the school context as socially hostile. The nature of the social hostility is described, but school leaders seem insensitive to many of the social integration challenges that confront dropouts. Several implications for school leadership have been drawn out, including the view that while there are a variety of leverage points for addressing the social hostility problems, the social development of dropouts who experienced hostility stand to wither if supportive measures are not implemented to help them reintegrate. While the research provides new insights into the experiences of dropouts in school, it had the limitation of being a case study whose findings cannot be generalised.

  • Description: Design guidelines are used in interaction design (IxD) for physical design and for evaluating the usability of designs and interactive products. Guidelines are widely used for physical design and evaluation, but have a number of problems. IxD patterns have been proposed as an alternative to guidelines, as they are claimed to have several advantages over guidelines. A small number of empirical studies provide evidence that patterns are beneficial when used in IxD. Additional research on the usefulness of IxD patterns is required. The primary research question investigated in this thesis was thus: How useful are IxD patterns as physical design and evaluation aids in IxD, as compared to design guidelines? The role of guidelines and patterns as design and evaluation aids in IxD was investigated and a comparison of guidelines and patterns, based on a set of guideline and pattern properties, was conducted. The concept of pattern and guideline usefulness was explored and a research agenda for guidelines and patterns was identified, together with a set of research questions for an empirical study. The empirical study of the use of patterns for evaluation, redesign and new design, as compared to guidelines, was conducted at the Nelson Mandela Metropolitan University in 2004. The participants were a purposive sample of post-graduate Computing students, who were regarded as novice interaction designers. Two equivalent groups were formed, one that used patterns and one that used guidelines. Patterns were found to be as useful as guidelines when used as evaluation aids. Guidelines and patterns were identified as effective tools for identifying and explaining usability issues and design features. Best-effort matched sets of guidelines and patterns produced substantially different result sets when used to identify issues and features, with fairly low overlap. A substantial evaluator effect was observed for the use of guidelines and patterns for evaluation, and the results obtained were similar to those obtained by Molich et al. in their Comparative Usability Evaluation (CUE) studies. There was no statistically significant difference between the effectiveness of guidelines and patterns for evaluation. There was also no statistically significant difference between the perceived efficiency, effectiveness and satisfaction in use of guidelines and patterns for evaluation. Guidelines and patterns were found to be used in similar ways for evaluation. Patterns were found to be more effective than guidelines for redesign. Patterns were found to be as useful as guidelines when used for new design. There was no statistically significant difference between the effectiveness of guidelines and patterns for new design. There was also no statistically significant difference between the perceived efficiency, effectiveness and satisfaction in use of guidelines and patterns for redesign and new design. Guidelines and patterns were found to be used in similar ways for design. There was no statistically significant difference between the perceived usefulness of the format, content, ease of learning, and usefulness as personal and shared design languages, of guidelines and patterns. Both participant groups were equally agreeable to using guidelines and patterns in the future. The perceived usefulness of pattern collections was found to depend on the usability of the collection interface and the content quality of the patterns. The results of the empirical study thus provided empirical evidence that patterns were as useful as guidelines for evaluation and new design, and were perceived as positively as guidelines were. Patterns were found to be superior to guidelines for redesign. Patterns can therefore be used with a measure of confidence as early stage design aids for physical design and evaluation in the future. In addition to these findings, a number of opportunities for further research were identified.

  • Description: The purpose of this research is to propose metrics to evaluate the user interface factors that impact on the user experience of Software Accounting Applications (SAAs) used to support the accounting business activities in Small Medium and Micro Enterprises (SMMEs) operating in developing countries. The research commences by outlining the conceptual background that introduces the study. In the introductory chapter, the problems together with the objectives that motivate the significance of the study are presented. In the same chapter, the overall research focus and how each of the research questions are treated to accomplish the intended goals are defined. In Chapter 2, the typical accounting business activities for SMMEs operating in developing countries are investigated. Findings from the preliminary survey revealed that Pastel accounting is the commonly used SMME accounting application used in developing countries. Inventory management, cash book processing, preparation of financial statements, customer and supplier documents processing are revealed as the most prevalent SMME accounting activities. This chapter highlights the problems that inhibit the implementation and the delivery of full benefits of using these SAAs. After indentifying the SAA problems, user experience aspects of the SAA are addressed in Chapter 3. User experience (UX) is defined and existing UX evaluation criteria are discussed. The findings form the basis for choosing the applicable criteria for evaluating the User Interface (UI) factors impacting on the UX of Pastel accounting. The proposed user experience evaluation metrics are described in Chapter 4. A discussion on how the metrics are implemented and what UI aspect they measure is presented. The research design and methodology followed is discussed in Chapter 5. The chapter outlines the possible research philosophy, strategy, methods and data collecting methods. A choice is made about the appropriate approach to answer the stated research questions to satisfy the intended overall research objective. A phenomenologist, qualitative inductive approach is adopted in the study. A contextual inquiry case-study strategy is chosen as applicable to this research. Data is collected using expert reviews, user observation and subjective questionnaires. After the choice of the research techniques, the case study results are presented and analysed in Chapter 6. It is found that Pastel UI is attractive and the users are happy with the visual design of the application. The major factors that impact on Pastel accounting are its lack of 4 feedback and its complexity which makes it difficult for first time users to use the application and the paucity of the help function. After the observed findings, the conclusions and recommendations of the research are presented in Chapter 7. It has been concluded that Pastel accounting UI fails to captivate a positive user experience for first-time users; the users do not find the expected help from the Help function and are often left wondering about the status of the system and the outcome of their actions on a task. Recommendations on how designers would make Pastel user interface more helpful, easy to use, and provide adequate feedback are presented in Chapter 7.

  • Description: Cultural and heritage tourism, one of the fastest growing segments of the tourism industry, is becoming a major pillar in the tourism strategy of many countries. Like elsewhere in the world, museums play a significant role in heritage tourism. South Africa has a rich history of intangible cultural heritage which manifests itself in oral history, traditional music and dance, social practices and indigenous knowledge systems. It is becoming more important for museum managers to identify the variables that will enhance the attraction and retention of museum visitors. The aim of the study was to determine tourists’ satisfaction with their visit to Port Elizabeth’s heritage museums by comparing their expectations and experiences. This could help museum marketers to better understand their customers, and design experiences that match their expectations. The literature review presented a brief overview of heritage tourism, the museum experience, and visitors’ satisfaction. Concepts of heritage tourism, functions of museums and the different museum attributes that might impact customer satisfaction were discussed. Literature on visitors’ satisfaction included descriptions of the expectations and approaches to measuring customer satisfaction. A museum satisfaction conceptual model resulted from these reviews. ii The proposed model was modified in the empirical study. The data were collected by means of a survey, using self-administered questionnaires distributed to visitors at three heritage museums in Port Elizabeth. Two hundred and twelve useable questionnaires were received. The empirical findings did not fully support the conceptual model. By conducting a factor analysis, the data was reduced to eight factors, namely, human interaction, physical evidence, facilities, facility quality, exhibition, edutainment, escape and aestheticism. It was found that the satisfaction mean scores were consistently higher than the expectation mean scores. This implies that museum visitors were satisfied with their experience of the three heritage museums in Port Elizabeth. Finally, the results of the paired sample t-test and regression analyses tested and explained formulated hypotheses. The principal recommendations emanating from this study are summarised in two groups, namely: • recommendations pertaining to the strategic implications of the findings in terms of service, facilities and experience. For example, the museum administration could establish more facilities for the disabled and the elderly, consider discounting and promotion programmes, and increase the use of technology in their displays. • recommendations for future research. For example, future studies could be applied to investigate visitors’ satisfaction with other heritage museums in South Africa.

  • Description: Small towns internationally and in South Africa are becoming increasingly marginalised, and they are often experiencing economic downturn, demographic shifts and a rearticulation of their role in the urban hierarchy. In the case of South Africa many of these small towns are also faced with low levels of social development. The urgent need to address such conditions is evident by the fact that a large proportion of the South African population resides in small towns, and their surrounding hinterlands. This said, there are examples of small towns, internationally and in South Africa which, through the use of various Local Economic Development actions, have managed to remain sustainable, and in some cases become economically viable localities once again. In light of the above, the research conducted for this thesis seeks first to establish the socio-economic changes occurring over time in three small towns in the Eastern Cape Province of South Africa, namely Stutterheim, Bedford and Hamburg. Secondly, the research aims to identify the nature of LED activities in the three small towns, highlighting those factors contributing to the success of LED initiatives as well as those factors inhibiting LED in small towns. This is done with the intention of developing future lessons for LED in small towns. The research was conducted using a mix of qualitative and quantitative data generated through the interviews with key role players in each town, as well as secondary data sources. Findings from the research suggest that the small towns investigated are characterised by low levels of socio-economic development. In addition, it appears that the development opportunities for the towns are limited. Current initiatives are being driven by private role players with local government being largely uninvolved. Such initiatives are limited in nature, with benefits only felt by small groups of the local community. However, examples do exist of where LED has successfully benefited the broader spheres of the local community, thus suggesting that if implemented properly such an approach does have potential to assist in the socio-economic development of small towns. In light of this, a number of lessons are identified for LED in small towns, including the need for strong leadership, community involvement, partnerships between role players, and planning for project sustainability.

  • Description: The poor performance in mathematics of learners in schools in Namibia, especially in the grades where learners sit for the national examinations, has been a concern of everybody. Since independence, the Ministry of Education in collaboration with several donor agencies has been aware of the poor performance in mathematics in the country. Several international and local studies have been made in an effort to identify the problems that are hindering learners’ performance in mathematics in Namibia. The findings of some studies that were conducted in the country such as the Southern Africa Consortium Monitoring Education Quality (2004), the Presidential Commission on Education, Culture and Training (1999), and the Mathematics and Science Teachers Extension Program (2002) revealed that the inadequate proficiency of primary teachers in mathematics content could be responsible for learners’ poor performance in mathematics. This study, therefore, is aimed at investigating the mathematical proficiency of lower primary (LP) teachers in Namibia. The study used three instruments to collect data namely, a profile questionnaire – to collect teachers’ demographic data, a proficiency test – to test their proficiency level of mathematics using the content of Grade 4 and 5 learners’ mathematics syllabi and a semi-structured interview schedule – to get views about their own mathematics content knowledge, attitudes towards mathematics as well as problems that hinder effective teaching and learning of mathematics at LP phase. The study was conducted with 30 lower primary teachers from five primary and combined schools in the Ohangwena circuit of the Ohangwena region. The study found out that: (1) the mathematical proficiency of LP teachers is below the Grade 7 Mathematics content. Most teachers are not able to solve the content of mathematics at upper primary (UP) phase. (2) LP education is receiving very little support from the Ministry compared to other phases. (3) There are no workshops or training courses organised for LP teachers. They do not receive enough textbooks and materials, their classrooms are overcrowded and teachers cannot pay attention to individual learners. (4) There is a dire need for LP Head of Departments (HODs) who are specialised at LP; most HODs for LP at schools are not specialised in this area. When it comes to views about future content of mathematics that should be given to LP teachers in Namibia, respondents recommended that future LP teachers should have knowledge of mathematics up to at least Grade 10 but preferably up to Grade 12. They do not want to be restricted to LP mathematics, but would like to have a broader knowledge of mathematics content. This would make them more confident in solving their children’s problems in mathematics. Overall, participants recognised the value of mathematics and the role that it plays in society.

  • Description: This research is based on a case study of MoAfrika, a news organisation that has embraced digitisation to produce and distribute content across three platforms. It draws upon observation and in-depth interviews to show how MoAfrika's embrace of a degree of convergence has led to a fragmentation for journalists whose daily work now include additional responsibilities and pressures of time. While there is an increase in the quantity of news disseminated via radio, newspaper and online, questions arise about the quality of such news produced in a multi-skilled, multiple media news production environment. The result is repurposed stories with little original content and augmented employee workloads without training and compensation. The study examines these issues drawing on theories of gatekeeping and convergence. The decision to include a news story at MoAfrika depends partly on which medium it fits into most easily. News values, deadlines, organisational norms and national trends are some of the considerations which factored into gatekeepers' decisions. Primary decision-making was made within a group which also considered expense and expertise, and where the Managing Editor made the final call and set the frameworks for how content played across the enterprise's three platforms.

  • Description: With the dawning of a new era in South African politics in 1994 it became evident that education was going to be re-organised along with other government structures in South Africa. I begin the study by reviewing this curriculum change in South Africa that has taken place since 1995. This involved the development Curriculum 2005 (C2005) and the subsequent revision of C2005, which is now the National Curriculum Statement (NCS). This curriculum introduced an environmental focus into all the Learning Areas, which gave teachers a mandate not only to teach about environmental concepts and issues (such as biodiversity) at schools but to also address them in the communities outside the schools. This study considers biodiversity issues as biodiversity is a new focus in South African policy more broadly, and particularly in the Natural Science Learning Area. Our school has received vegetable and indigenous plant gardens from the South African National Biodiversity Institute, which provides a rich new resource for teaching about biodiversity, particularly in the Natural Sciences. My interest in the study was to investigate how schools (teachers) can use school gardens in the recontextualisation of the National Curriculum Statements focusing on the Natural Science Learning Area in Grade 7 at my school. I used Bernstein’s (1990) concepts of delocation, relocation, ideological transformation and selective appropriation and Cornbleth’s (1990) theory of curriculum contextualization to understand and interpret the recontextualisation process in the four lessons studied. In this research I was involved in the planning of the lessons with the Grade 7 Natural Science teacher. I taught one lesson as a demonstration and then observed while the teacher taught the other three lessons. I conducted this study as an action research case study. I used focus group interviews, classroom observations, document analysis and interviews as methods of data collection. The study found that the use of school gardens for teaching biodiversity can help with the recontextualisation of NCS in schools, and for the teaching of biodiversity, but that there is a need to understand and address various recontextualisation issues if this is to be done effectively. The study revealed that use of the school gardens for learning about biodiversity in the NS Learning Area is influenced by teachers’ knowledge, experience, teaching styles and available resources, as well as management issues and the complexity of the NCS discourse itself. The study also revealed that socio-cultural and structural factors (e.g. language and class size) also affect how biodiversity is taught in schools, and thus how the recontextualisation of the NCS takes place. The study concludes by making recommendations for taking this work forward in the context of our school as it addresses the gap that exists between policy and practice.
