- Description: The restructuring of higher education through incorporations and mergers has attracted a lot of attention over the past few years in South Africa. These incorporations and mergers have displaced institutions of higher education and positioned them in new organisational homes, thus subjecting faculties, schools and departments to a process of relocation, new knowledge acquisition, identity change and meaning-making processes. The merger has resulted in three types of universities; i.e. traditional universities, comprehensive universities and universities of technology. The introduction of the comprehensive university as a new institutional type has brought with it questions about the idea of the university and the purpose of higher education in general. Mergers in particular have initiated conversations about sense-making and meaning during change. Amidst all this, people within the merging institution have been confronted with a new organisation with which they have to identify. At universities in particular, questions about academic identity and organisational identity have become unavoidable. The boundaries that gave definition to a university have been (re)moved. The structure of the university, as it was known, has changed. Hence, in the newly merged NMMU, academics are in the process of internalising and giving meaning to the new organisational values and norms of a comprehensive university. Needless to say, the challenges facing the newly merged NMMU are cultural, structural and geographic. Bringing together different institutional and personal cultures involves a human dimension that needs to be nurtured by trying to form a coherent and cohesive organisation that is created from culturally diverse and uncomplementary institutions. Another challenge is bringing together different organisational structures, systems and programmes that are informed by different institutional cultures. Furthermore, the challenge of having multiple campuses that are geographically separated exacerbates the situation. Along with all these challenges, the NMMU has the task of constructing an integrated institutional identity through organisational forms and programme models that will embody the multiple functions that are typical of a comprehensive university. The aim of the current study was to explore how the meanings that academics assign to the notion of a comprehensive university are instrumental in constructing an organisational identity; describing in detail how at the NMMU academics make meaning of the comprehensive university and how that meaning-making process influences the construction of an organisational identity; and formulating recommendations based on the qualitative findings and quantitative results of the research. In an effort to achieve the aim alluded to above, this study employed the mixed methods approach that used a sequential, exploratory, transformative design. The complexity of the study was such that it required to be investigated through qualitative and quantitative analytical methods in order to confirm, triangulate and obtain a holistic picture of the situation under investigation. The sample for the qualitative interviews consisted of thirteen purposefully selected academics from all levels at the NMMU. The interviews were transcribed and coded into themes, categories and sub-categories. These themes were then developed and translated into statements for the questionnaire that was administered randomly to all NMMU academics. A total of 108 academics responded to the questionnaire. The responses to the questionnaire were analysed using the SPSS programme. The findings and results of the study revealed that there was a fairly common understanding of the term comprehensive university among academics. However, the details about its procedures appeared to be the privileged ownership of management. This situation mitigated the necessity for a sense-making process that would allow for negotiation, modification and alteration of already held assumptions. A pertinent concern amongst academics was the neglect of the ‘human factor’ during the change process. The management style also came under scrutiny, especially in terms of the facilitation and mediation of change. There was a consensus on the call for cohesion and unity that was believed to be one of the main features that would make the construction of the NMMU organisational identity possible. The vision, mission and values of the NMMU were believed to be central to the creation of cohesion and unity, which would subsequently result in the birth of an organisational culture that could inform the organisational identity of the NMMU. Strategies to actualise and realise the organisational identity were proposed by participants. Notwithstanding, the impact of the merger was identified as having a major influence in shaping the organisational identity of the NMMU.

A critique of baroque performance practice with specific reference to the organ preludes and fugues by Johann Sebastian Bach

- Description: This study aims to provide a critique of Baroque performance practice, with specific reference to the organ Preludes and Fugues of Johann Sebastian Bach. Drawing from the extensive body of literature pertaining to Bach’s keyboard music, a number of relevant issues are explored in so far as these may provide understanding of the manner in which the organ Preludes and Fugues should be performed today. These include: • The notion of Bach’s ‘generic’ keyboard works. Were the generic keyboard works as a whole intended to be performed on more than one keyboard instrument? The instrumental designations given by Bach in these works are a valuable source of information in answering this question. • The type of organ that was known to J.S. Bach and typical registration used in the Baroque, called the plenum. • Identification of the grey area that persists in the interpretation of Bach’s organ works with regard to registration, tempo, rhythm, articulation, phrasing, fingering and ornamentation. This study also engages with the current authenticity debate in musical performance as seen from the modernist and postmodernist points of view. The modernist ideal of authenticity is to “re-create” or “reconstruct” performances of Bach’s music with as much accuracy as the evidence of historical musicologists can provide. For the postmodernist, however, authenticity lies in embracing the human element of contingency in musical performance, along with a thorough grounding of such performance in historical evidence. In aligning itself with the postmodernist point of view, this study ultimately argues that we cannot learn everything there is to know about Baroque performance practice from books. Instead, in addition to historical evidence, we draw much of our understanding in this regard from our innate or tacit levels of knowing. In this regard the scholar of Bach’s organ works can draw valuable lessons from the levels of tacit knowledge of leading organ pedagogues and performers on the subject of Baroque performance practice.

A difficult equilibrium: torture narratives and the ethics of reciprocity in apartheid South Africa and its aftermath

- Description: This thesis takes the form of an enquiry into the development of the ―generic contours (Bakhtin 4) for the narration of torture in South Africa during apartheid and its aftermath. The enquiry focusses on the ethical determinations that underlie the conventions of this genre. My theoretical framework uses Adam Zachary Newton‘s conceptualization of narrative ethics to supplement Paul Ricoeur‘s writings on narrative identity and the ethical intention, thus facilitating the transfer of Ricoeur‘s abstract philosophy to the realm of literary criticism. Part I presents torture as a disruption of narrative identity and a defamiliarization of the intersubjective encounter. The existence of torture narratives thus attests to the critical role of narration in the reconstruction of the tortured person‘s identity and the re-establishment of benign frameworks of intersubjective communication. Literature‘s potential to act as a laboratory for the testing of the limitations of narrative identity and the resilience of ethical mores suggests that the fictional representation of torture also has an important role to play in this attempt at rehabilitation. Part II takes the form of a comparative analysis of non-fictional and fictional accounts of torture originating from apartheid South Africa. This shows that the ethical determinations underlying the narration of torture in South Africa range from intersubjective estrangement to a ―solicitude of reciprocity (Bourgeois 109). However, because the majority of these texts used the presentation of human rights abuses to galvanize international opposition to apartheid, the scope for experimentation was limited by the political exigencies of the time. Part III examines the stylistic and generic shifts in the narration of torture that accompanied South Africa‘s transition to democracy. It suggests that the discursive dominance of the Truth and Reconciliation Commission replaced the fruitful—in literary terms—dialogue between authoritarianism and resistance that characterized the apartheid era with a monologic grand narrative of emotional catharsis, reconciliation and nation building. It also suggests that the ―truth-and-reconciliation genre of writing (Quayson 754) that shaped the literary milieu of the post-TRC period be seen in terms of a resurgence of the apartheid–era paradigms for the narration of human rights abuses that were repressed during the initial phase of democratic transition. By framing the TRC as a catalyst for individual journeys of self-discovery, these novels raise important questions about what it means to be a part of the ―new South Africa. In contrast to the majority of apartheid era literature, the novels of the post-TRC period privilege the literary prerogative over the political, and thus bring to fruition the experimental potential of the previous paradigm. In doing so, they not only go beyond solicitude to achieve an ―authentic reciprocity in exchange (Ricoeur, Oneself 191), but also initiate a process of long-awaited literary expansion, in which authors look beyond the limits of apartheid and begin to critically engage with the region‘s pre-apartheid history and its post-apartheid present.

- Description: The notion of a global knowledge society is somewhat of a misnomer due to the fact that large portions of the global community are not participants in this global knowledge society which is driven, shaped by and socio-technically biased towards a small fraction of the global population. Information and Communication Technology (ICT) is culture-sensitive and this is a dynamic that is largely ignored in the majority of ICT for Development (ICT4D) interventions, leading to the technological determinism flaw and ultimately a failure of the undertaken projects. The deployment of ICT solutions, in particular in the context of ICT4D, must be informed by the cultural and socio-technical profile of the deployment environments and solutions themselves must be developed with a focus towards context-sensitivity and ethnocentricity. In this thesis, we investigate the viability of a software architectural framework for the development of ICT solutions that are context-sensitive and ethnocentric1, and so aligned with the cultural and social dynamics within the environment of deployment. The conceptual framework, named PIASK, defines five tiers (presentation, interaction, access, social networking, and knowledge base) which allow for: behavioural completeness of the layer components; a modular and functionally decoupled architecture; and the flexibility to situate and contextualize the developed applications along the dimensions of the User Interface (UI), interaction modalities, usage metaphors, underlying Indigenous Knowledge (IK), and access protocols. We have developed a proof-of-concept service platform, called KnowNet, based on the PIASK architecture. KnowNet is built around the knowledge base layer, which consists of domain ontologies that encapsulate the knowledge in the platform, with an intrinsic flexibility to access secondary knowledge repositories. The domain ontologies constructed (as examples) are for the provisioning of eServices to support societal activities (e.g. commerce, health, agriculture, medicine) within a rural and marginalized area of Dwesa, in the Eastern Cape province of South Africa. The social networking layer allows for situating the platform within the local social systems. Heterogeneity of user profiles and multiplicity of end-user devices are handled through the access and the presentation components, and the service logic is implemented by the interaction components. This services platform validates the PIASK architecture for end-to-end provisioning of multi-modal, heterogeneous, ontology-based services. The development of KnowNet was informed on one hand by the latest trends within service architectures, semantic web technologies and social applications, and on the other hand by the context consideration based on the profile (IK systems dynamics, infrastructure, usability requirements) of the Dwesa community. The realization of the service platform is based on the JADE Multi-Agent System (MAS), and this shows the applicability and adequacy of MAS’s for service deployment in a rural context, at the same time providing key advantages such as platform fault-tolerance, robustness and flexibility. While the context of conceptualization of PIASK and the implementation of KnowNet is that of rurality and of ICT4D, the applicability of the architecture extends to other similarly heterogeneous and context-sensitive domains. KnowNet has been validated for functional and technical adequacy, and we have also undertaken an initial prevalidation for social context sensitivity. We observe that the five tier PIASK architecture provides an adequate framework for developing context-sensitive and ethnocentric software: by functionally separating and making explicit the social networking and access tier components, while still maintaining the traditional separation of presentation, business logic and data components.

- Description: The aim of this dissertation is to extract information from shipwreck survivor narratives, which will add to the known body of knowledge of the pre-colonial history of Southern Africa during the years 1552 to 1782. The discourse analysis focuses on the voice of the African peoples where the Europeans are the 'Strangers', the 'Other', reversing the view that the people of non-European cultures were termed as the 'Other'. Indigenous inhabitants of south-east Africa, south of Kosi Bay, first encountered Europeans in 1552 when a Portuguese ship was wrecked at present-day Port Edward. Subsequently, eight more Portuguese ships were wrecked between Plettenberg Bay and Kosi Bay between the years 1554 to 1647. Two Dutch ships landed on the shore, one south of the Bay of Natal in 1686, and the other being wrecked near the mouth of the Keiskamma River in 1713. There were also two English ships, with one striking the rocks on Bird Island in Algoa Bay in 1755 and the other, the more famous Grosvenor of 1782, coming aground at Lambazi Bay, north of the Mzimvubu River. The survivor groups were large, varying in size from 72 to 500, and most included a large complements of slaves. The survivors of the Portuguese ships made their way to present-day Mozambique where the Portuguese had trading outposts. The survivors of the Dutch ships, as well as those of the Grosvenor tried, with limited success, to make their way to Cape Town. The survivors from two of the Portuguese wrecks and the English group on Bird Island, constructed small ships and managed to sail away.

- Description: There is confusion in the literature concerning the taxonomic status of the Turdus smithi—T. olivaceus species complex. Here we attempt to clarify morphological differences within this complex. In addition, we attempt to clarify identification of the respective taxa. Although mean measurements of morphometric features differed significantly between species and subspecies, these features are not useful in separating species or subspecies due to considerable overlap in measurements. Furthermore, there were often larger differences between subspecies of T. olivaceus (particularly the geographically isolated T. o. swynnertoni) than between T. olivaceus and T. smithi. We therefore suggest that further work investigates the elevation of T. o. swynnertoni to full species status. Plumage characteristics proved more useful in separating T. olivaceus and T. smithi in the field, except in regions where the distributions overlap (potential hybridisation zones). We highlight the importance of clarifying the delineation of separate species particularly with respect to bird census data (e.g. Southern African Bird Atlas Project 2) and studies related to these species.

- Description: There is confusion in the literature concerning the taxonomic status of the Turdus smithi—T. olivaceus species complex. Here we attempt to clarify morphological differences within this complex. In addition, we attempt to clarify identification of the respective taxa. Although mean measurements of morphometric features differed significantly between species and subspecies, these features are not useful in separating species or subspecies due to considerable overlap in measurements. Furthermore, there were often larger differences between subspecies of T. olivaceus (particularly the geographically isolated T. o. swynnertoni) than between T. olivaceus and T. smithi. We therefore suggest that further work investigates the elevation of T. o. swynnertoni to full species status. Plumage characteristics proved more useful in separating T. olivaceus and T. smithi in the field, except in regions where the distributions overlap (potential hybridisation zones). We highlight the importance of clarifying the delineation of separate species particularly with respect to bird census data (e.g. Southern African Bird Atlas Project 2) and studies related to these species.

- Description: Alien invasive species pose a great threat to ecosystems and human communities (Richardson & van Wilgen 2004; Hobbs & Humphries 1995). On private lands, there is a need to find institutional, administrative and scientific responses to the alien plant problem that operate beyond the scale imposed by property boundaries (Slocombe 1998; Grumbine 1994). One such response is the development and support of institutions, such as the St Francis Conservancy, that foster cross-boundary management of landscapes (Hurley et al. 2002). This study seeks to promote collective decision-making and collaborative management by private landowners through the development of a resource allocation system for the control of alien invasive plants on the St Francis Conservancy. The conservancy is located in the south-eastern lowlands of the Cape Floristic Region, between the villages of Cape St Francis and Oyster Bay, and is comprised of the properties of multiple landowners. Mutliple Criteria Decision Analysis (MCDA) and Geographical Information Systems (GIS) techniques were integrated to provide a spatially explicit resource allocation system that considered environmental, social and economic concerns. The MCDA technique selected for use was the Analytical Hierarchy Process (AHP). This technique has a record of providing robust, defensible decisions and enabled the resource allocation decision-problem to be decomposed into a hierarchy of objectives, criteria and indicators. Stakeholders participated in the development of the resource allocation system, especially through providing input into the determination of the relative importance of criteria and indicators through the assignment of weights. Various weighting scenarios were presented and these were interpreted into an ii implementation plan. The costs and effort required to clear alien plants were estimated, and obstacles facing the implementation of the plan were identified.

- Description: The main aim of this study was to assess the impact of the Best Management Practices (BMP) project on social and economic wellbeing at Zanyokwe Irrigation Scheme (ZIS) in central Eastern Cape Province. The BMP project is a knowledge-based initiative aimed at introducing management practices (mainly soft skills) in order to improve production and livelihoods in the study area. The study employed a survey to collect socio-economic data amongst farming households. The 2005 situation analysis, which was conducted amongst the same respondents before the introduction of the new practices allowed for comparisons in order to track changes or impacts after the implementation of the project. Also, the social and economic impact assessment (SEIA) framework was used to assess the impacts. The results of the impact assessment showed the BMP project to have an impact on social and economic well being of households. The skills introduced were in the areas of water management, agronomic practices, marketing and institutional arrangements. More than 90% indicated that there was improvement in agronomic practices and water management and 68% in marketing. More than half of farmers worked in their farms on a daily basis, which is a big change as none of the farmers worked during weekends in 2005. The average time spent on the farms also increased from four (in 2005) to seven hours (this investigation) on average per day. The BMP project also had a positive impact on social relationships and networks between farmers and the BMP project team as well as well as farmers and non-farmers. Land use intensity improved due to increases in acreage of main crops as well as cultivating at both seasons. More than 40% of farmers cropped their land at both seasons (winter and summer). In 2005, most of the land was fallow in winter. While some of the new practices introduced had a negative impact on input expenditures, the returns were positive. These extra efforts and expenditures resulted in improvement in incomes. Agricultural contribution to household income increased from 71% in 2005 to 81% in 2007. The increase in household incomes had a positive effect on poverty and food security status of households. The proportion of households earning incomes that are below poverty line dropped from 61% in 2005 to 38% in 2007. Changes in the diet of the households were noticed. In addition to the consumption of staples such as samp, maize meal and rice, people added a variety of vegetables. Own production was the main source of these vegetables as was indicated by 66% of respondents compared to only 25% in 2005. Food remained the main expenditure category though, as was the case in 2005. Improvements in marketing such as performing extra marketing functions and adopting a marketing strategy (collective action) also led to improvements in economic wellbeing.

- Description: Since the inception of the new dispensation, entrepreneurship has been identified as one of the key enablers of economic participation. For this reason the government has established strategic institutions and mandated them to promote entrepreneurship in the country with the aim of increasing economic participation and entrepreneurial activities. One of the key and the fastest growing industries that have been identified as needing attention with regards to increasing participation of the women entrepreneurs is the tourism industry. There is now a noticeable growth of women entrepreneurs in this industry. They are found running bed and breakfasts (B&Bs) and conducting tours in urban areas as well as townships and rural areas. This is further evident if one looks at the value chain in the tourism sector. However, women entrepreneurs that are found in this sector are facing specific challenges that hinder their progress towards achieving sustainable businesses, especially those running or intending to run B&B businesses. Some of these challenges are sector related and some are just inherent to pursuing an entrepreneurial journey. The participation of women in the mainstream of entrepreneurship presents unique challenges as well. Women were never allowed to participate fully in the entrepreneurial activities. The latter still contributes to the challenges faced by women in their journey towards developing and operating sustainable businesses irrespective of the industry in which they operate in. Based on the above discussion, the main problem statement of this study is: To develop a strategic entrepreneurial model to enable female entrepreneurs to operate sustainable B&B businesses in the tourism industry.

- Description: This study is influenced by the objectives of the Mainstreaming Environment and Sustainability in African Universities Partnership which aims to enhance the quality and relevance of university education through implementation of Environmental Education and sustainability across university functions and operations. It contributes to Education for Sustainable Development through the development of tools to assess sustainability in higher education, investigating sustainability practices in universities and proposing strategies for improving mainstreaming of sustainability. It also contributes to systems approaches in mainstreaming contextual sustainability challenges in university functions and operations. The aim of the study was to investigate how universities can mainstream sustainability in their functions and operations in response to contextual sustainability challenges in a changing environment using a systems approach. The research was a case study of Rhodes University in South Africa, which is situated in the impoverished Eastern Cape Province. The study involved 12 teaching departments (representing all faculties at the university), four research units and institutes, five managements units, the Estates Division and the Student Representative Council. The theoretical framework of the study draws from a critical realist ontology and systems thinking epistemology. Systems thinking emphasises the interdependencies of phenomena, thus providing the methodology and tools for a systems view of relationships between education and the environmental context in which it is embedded. Critical realism was employed as an underlabourer to systems thinking as it provides for some of the dimensions absent in systems thinking including its depth ontology which facilitates isolating causal factors influencing empirical reality. It recognises that explanation of phenomena can be embedded in history and acknowledges the fallibility of knowledge. The data collection methods employed in the study include a sustainability assessment using a Unit-based Sustainability Assessment Tool developed as part of the study, interviews, content analyses and observations. Data analyses were performed through employing morphogenetic analysis, and inductive, abductive and retroductive modes of inference. The morphogenetic analysis of social transformation/reproduction was employed to trace the historical emergence of sustainability initiatives at Rhodes University. Induction facilitated reorganisation of the data into themes which particularly represent the main sustainability activities at Rhodes University. Abduction, through recontextualising data in a systems thinking framework, enabled further insights into the phenomena. In the study, it enabled use of systems lenses as a framework and led to identification of systemic issues affecting mainstreaming and later, the development of systems thinking approaches in mainstreaming sustainability. Retroduction enabled identification of causal mechanisms which influenced the emergence of sustainability initiatives at the university. The study established that the emergence of sustainability initiatives at Rhodes University followed the 1990 Talloires Declaration and paralleled international institutional developments in relation to environmental and sustainability challenges. Since then, sustainability initiatives have continuously been emerging in various operational dimensions of the university in line with emerging sustainability challenges which resulted in a morphogenetic cycle. The study revealed that Rhodes University has mainstreamed sustainability across the functions and operations of most of the departments/divisions/units forming part of the study, especially in functions like teaching, research, community engagement and operations. There were a few exceptions like the Human Resources Division and to an extent the Research Office/Management Division which are not yet considering sustainability in their operations. While most of the teaching departments had sustainability initiatives in teaching, research and community engagement, there was diversity in the dimension(s) of sustainable development that the departments addressed and this seemed to relate to the disciplinary content of their subjects. In the Estates Division sustainability initiatives included sustainable landscaping, campus environmental management, water and energy conservation initiatives, waste recycling, use of biodiesel, to mention a few. Students were also involved in various sustainability activities especially through voluntary community engagement initiatives. Sustainability initiatives at the university were also discovered to be embedded within and responding to sustainability challenges of the immediate university environment of Makana District. The study unearthed the causal mechanisms enabling and constraining mainstreaming activities at the university. These were found to be embedded in the history and context within which the university is operating, and other factors related to university structures and agency of lecturers, other employees and students. Examples of these factors are unsustainable patterns in society, policies and the need to redress past inequalities. The study noted the existence of systemic issues at the university which need to be addressed to enable and enhance the promotion of a systems approach to mainstreaming: notably, complexity owing to diversity of approaches employed in mainstreaming, the absence of clearly defined university sustainability goals, problems of institutional support and in some cases, disciplinary governing rules which do not leave room for mainstreaming sustainability. The study established the possibility of improving mainstreaming of sustainability through the adoption of more explicit systems approaches. It suggests use of systems models including the systems-environment model, the functions/structure model and the motion picture model in the process. It recommends making the goal of mainstreaming more upfront, developing a shared understanding of sustainability and mapping out/defining contextual sustainable development issues to grapple with. The study also recommends adopting a holistic approach in mainstreaming, making it a campus-wide initiative, involving all students and developing interdisciplinary curricula. It suggests setting up of supporting mechanisms to strengthen, extend and spearhead mainstreaming and enhancement of collaborative work in sustainable development issues.

- Description: It has been suggested that plants which are good colonizers will generally have either an ability to self-fertilize or a generalist pollination system. This prediction is based on the idea that these reproductive traits should confer resistance to Allee effects in founder populations and was tested using Gomphocarpus physocarpus (Asclepiadoideae; Apocynaceae), a species native to South Africa that is invasive in other parts of the world. We found no significant relationships between the size of G. physocarpus populations and various measures of pollination success (pollen deposition, pollen removal, and pollen transfer efficiency) and fruit set. A breeding system experiment showed that plants in a South African population are genetically self-incompatible and thus obligate outcrossers. Out-crossing is further enhanced by mechanical reconfiguration of removed pollinaria before the pollinia can be deposited. Selfpollination is reduced when such reconfiguration exceeds the average duration of pollinator visits to a plant. Observations suggest that a wide variety of wasp species in the genera Belonogaster and Polistes (Vespidae) are the primary pollinators. We conclude that efficient pollination of plants in small founding populations, resulting from their generalist wasp-pollination system, contributes in part to the colonizing success of G. physocarpus. The presence of similar wasps in other parts of the world has evidently facilitated the expansion of the range of this milkweed.

- Description: This treatise provides recorder performers and teachers with a guide to understanding the unconventional notation symbols encountered in Music for a Bird by Hans-Martin Linde and Sieben Stücke Für Altblockflöte by Markus Zahnhausen. Given the context of the overall history of notation, it argues that the idiosyncrasies of the unconventional notation symbols encountered in the recorder repertoire of contemporary composers such as Linde and Zahnhausen are by no means an anomaly. Throughout history, notated scores have functioned merely as incomplete guides to the reconstruction and the realization of musical works. Along with the decoding of these instructions, a host of acculturated meanings have always been taken for granted on the part of the writers of such guidelines. In the light of the modernist crisis and the resultant exacerbation of the gulf between composers and their audience, however, it would seem that the need for such acculturated intervention is greater then ever before. This treatise serves to bridge the gulf between the works of Linde and Zahnhausen on the one hand, and the average performer and teacher of the recorder on the other, by offering an analysis both of the meaning of the unconventional symbols these works contain as well as of the method according to which they should be executed on the recorder.

Given the context of the overall history of notation, it argues that the idiosyncrasies of the unconventional notation symbols encountered in the recorder repertoire of contemporary composers such as Linde and Zahnhausen are by no means an anomaly. Throughout history, notated scores have functioned merely as incomplete guides to the reconstruction and the realization of musical works. Along with the decoding of these instructions, a host of acculturated meanings have always been taken for granted on the part of the writers of such guidelines. In the light of the modernist crisis and the resultant exacerbation of the gulf between composers and their audience, however, it would seem that the need for such acculturated intervention is greater then ever before. This treatise serves to bridge the gulf between the works of Linde and Zahnhausen on the one hand, and the average performer and teacher of the recorder on the other, by offering an analysis both of the meaning of the unconventional symbols these works contain as well as of the method according to which they should be executed on the recorder.

An anthropological study of witchcraft-related crime in the Eastern Cape and its implications for law enforcment policy and practice

- Description: This research sought to investigate the phenomenon of witchcraft-related crime in the Eastern Cape Province of South Africa, and its implications for law enforcement policy and practice. The primary motivation for a study such as this emerged from the need to address the lack of academic knowledge about witchcraft-related crime, especially in the Eastern Cape. The study is anthropological in focus, and is thus based on anthropological techniques of data gathering. Specifically, a literature study and fieldwork (semi-structured interviews and case studies) formed the basis of the research methodology employed. The geographical focus of the study was the northeastern part of the former Transkei, an area commonly referred to as Pondoland. Interview data were obtained from two categories of informants, namely community informants and informants of the South African Police Service (SAPS). Various towns and their surrounding villages were visited during fieldwork in order to gather data through interviews. Witchcraft continues to play an integral role in the cultural interpretation of misfortune, illness and untimely or mysterious death, particularly among local Xhosa-speaking communities that are predominantly rural. Beliefs associated with witchcraft were widespread in the study area and this was linked to high frequencies of witchcraft accusations and witchcraft-related violence. Police investigations of witchcraft-related cases were, for the most part, evaluated negatively by the majority of local community informants, while the SAPS informants indicated mixed responses as to the success of their investigations of these cases. The high frequency of unreported cases suggested that witchcraft-related crime is a problem in the Eastern Cape and that the local police were struggling to deal with these cases. The traditional leadership in various communities also struggled with the problem of an ambiguity in their role regarding witchcraft cases. Traditional leaders not only had jurisdictional limitations, but also indirectly seemed to encourage witchcraft-related violence by punishing those who accused others of witchcraft. In general, the relationship between communities, traditional leaders and the police were strained by witchcraft-related cases.

- 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.

- Description: According to Jensen (2000:215), though we talk of the growing digital divide between rich and poor countries, Africa has shown encouraging signs that it is rapidly adopting the Internet and making innovative use of the technology. Nevertheless, the continent is still well behind other developing regions of the world in taking advantage of the information and communication revolution. The main reasons for this are the limited and expensive telecommunication infrastructure, small markets, and lack of skills and awareness. At the end of 1996, just 11 of Africa’s 54 countries had local Internet access, but by February 2000 all of the continent’s countries had access in the capital cities (Jensen 2000:215). Excluding South Africa, the number of computers permanently connected to the Internet in Africa exceeded 10,000 early in 1999 (Jensen 2000:215). By January 2000, the total had increased to about 25,000, which means Africa, with an estimated population of 780 million people, has about as many Internet-connected computers (hosts) as Latvia, which only has a population of 2.5 million (Jensen 2000:215). Measuring the actual number of Internet users is difficult, but figures for the number of dial-up accounts supplied by Internet service providers (ISPs) show that Africa has more than 500,000 subscribers (Jensen 2000:215). Each computer with an Internet or e-mail connection supports an average of three users, a recent study by the UN Economic Commission for Africa (ECA) has found (Jensen 2000:215). This puts current estimates of the number of African Internet users at somewhere around 1.5 million. Most are in South Africa with approximately 1 million (Jensen 2000:215). Apart from the widespread use of Internet for business and entertainment purposes, social networking sites are becoming widely popular in South Africa. Although there has been little academic research on social networking sites in South Africa, there have been a few articles on websites, newspapers, and magazines that have touched on this phenomenon. Social networking sites, particularly Facebook, have become very popular among the adult internet user population, as both business and private applications. BMW South Africa, for example, has a Facebook page where video posts of recent car models and photos of cars are placed. The Facebook page also has a link to the company’s website (www.bmw.co.za) on the profile which takes a user straight to the commercial website. FM Tech (www.fmtech.co.za) is technology industry news and opinion website edited by Duncan McLeod, associate editor at the Financial Mail, South Africa’s top-selling and best-read weekly business, technology and current affairs magazine. McLeod’s article, What SA Internet users searched for in 2008, revealed that “Facebook”, “Cape Town” and “games” are the terms that South African Internet users searched for most often in 2008. Farber (2008) suggests that this is according to the results of US Web search giant Google’s annual “Zeitgeist” survey of the top searches worldwide. Farber also includes the year’s list of fastest-rising search terms which showed an enormous interest in international social networking sites. 1.2 Articles from popular media The following four popular articles describe the nature of social networking sites and its influence on South African users. Article 1: Cathryn Reece (2007) wrote an article entitled Facebook fever grips SA. “Cape Town - South Africans have embraced the internet social networking revolution, with over 50 000 new users signing on to the local Facebook network. The Facebook "South Africa" network currently has over 87 000 members - up from 35 000 in May.

- Description: Vegetation stress as a form of degradation is a widespread problem in many catchments in the Eastern Cape province. The Keiskamma is one of the catchments where considerable parts of the thicket biome are stressed. This necessitates an assessment of the status of the thicket biome by way of detecting vegetation stress in the area. The underpinnings of vegetation stress are investigated in this study. As a basic method to evaluate the thicket condition, remotely sensed data were acquired. High resolution ASTER imagery for the Keiskamma area at two different dates (2001 and 2005) was used to compute SVI and NDVI as indicators of vegetation stress conditions. A Digital Elevation Model (DEM) was used to derive slope angle and aspect. By way of digitizing from ortho-photo maps, various land-use types were mapped using Arc View GIS. The relationship between land use, terrain, soil erosion and vegetation stress was established. Field based techniques comprising stomatal conductance measurements were used and compared to remotely sensed data. The SVI and NDVI resultant images expressed similarities in areas depicting vegetation stress conditions at both epochs. A strong linear regression between NDVI and stomatal conductance measurements (mmol/m²) serve to confirm that the NDVI is a reliable indicator of vegetation stress condition. Slope angle and aspect were found to have a significant influence on vegetation stress conditions. Similarly variations in soil moisture and soil surface condition have strong implications for vegetation stress. Amongst other land-use types, abandoned lands were found to have the lowest NDVI values implying an association with the worst vegetation stress scenarios. It was concluded that an element of persistent stress conditions exists amongst the thicket vegetation of the Keiskamma catchment. This was mainly due to land use activities in the area.

- Description: Over three decades of research has shown that memories have significant effect on the behaviour, attitudes, beliefs, and identities of individuals and collectives, revealing also how experiences of trauma and acts of narrativisation have pertinence to the ways in which memories are stored and reconstructed. In this thesis a link is developed between memory, trauma, narrativisation processes and the interpretation of works by Jane Alexander, a contemporary artist whose work is informed by observations about South African life. Alexander’s sculptures are revealed to be not only important vessels of collective memories and experiences, but also evocations of individuals’ countermemories and traumas that remain unarticulated and invisible. Through an exploration of the workings of memory and its relation to her art, it is revealed how the past continues to exert its influence on many of South Africa’s present sociopolitical concerns and interpersonal dynamics. Indeed constantly changing memories have a significant effect on future generations’ perceptions of, and connectedness to, the past. While theories about memory have been deployed in Art History as well as the Humanities in general, Alexander’s work has not previously been considered in light of the influence of these ideas. This thesis thus contributes a new dimension to literature on the artist.

- Description: Temporarily open/closed estuaries (TOCE’s) are the numerically dominant type of estuary accounting for ≈ 70 % of all estuaries along the South African coastline. Despite their numerical dominance, aspects of the biology of organisms within these systems, particularly macrocrustacea remain poorly understood. This study firstly assessed the abundance and biomass of the most common isopod, Exosphaeroma hylocoetes, in three Eastern Cape TOCE’s, (the West Kleinemonde, East Kleinemonde and Kasouga Estuaries), and their response to mouth breaching events. This study was followed by aspects of the biology of the isopod including their utilisation of submerged macrophytes as a refuge from predation and/or possible food source, as well as the growth rates of the isopods in the laboratory under different environmental conditions. Mean isopod abundances and biomasses ranged between 0 and 4 791 ind. m⁻² and 0 and 9.65 mg dwt. m⁻² in the West Kleinemonde Estuary and between 0 and 108 ind. m⁻² and 0 and 0.318 mg dwt. m⁻² in the nearby East Kleinemonde Estuary. In the Kasouga Estuary, the values ranged between 0 and 3 650 ind. m⁻² and 0 and 5.105 mg dwt. m⁻². Temporal and spatial changes in the abundance and biomass of E. hylocoetes within the three systems was primarily linked to mouth phase, with populations declining when the mouth was open and to a lesser extent, seasonality. In all three estuaries maximum isopod abundances and biomasses were recorded in their middle and upper reaches, which could be ascribed to the presence of submerged macrophytes particularly Ruppia maritima, in two of the estuaries. Males (5.71 ± 0.41 mm) were significantly larger than females (3.99 ± 0.26 mm), but the sex ratios were skewed in favour of females, (a common feature in many isopod populations). Females were found carrying brood throughout the study, releasing offspring directly into the water column, to allow recruitment to the populations. The larger the female, the larger the brood carried (up to a maximum of 72 embryo/mancas). Results of laboratory experiments indicate that the close association of Exosphaeroma hylocoetes with submerged macrophytes is a result of the plant stands providing a refuge against predation by selected ichthyofauna. However stable carbon isotope and fatty acid analyses indicate that E. hylocoetes made use of ephiphytic algae and detritus on the stems of R. maritima, rather than the submerged macrophyte itself. There were no significant differences in the growth rates of male and female isopods at combinations of temperature (15 and 25 °C) and salinity (15 and 35 ‰). Laboratory growth studies revealed that males lived longer than females (25.77 ± 3.40 weeks vs 21.52 ± 3.00 weeks), and therefore achieved larger overall size. Females, however, reached sexual maturity (at 2.5 mm) at a faster rate (two to four weeks) than males (5.5 mm after 6.5 to 11 weeks), dependent on temperature. Exosphaeroma hylocoetes with its association with submerged macrophytes, early maturity, its growth rates and longevity, female-biased sex ratios and year-round breeding, all contribute to its success in temporary open/closed estuaries.

- Description: Temporarily open/closed estuaries (TOCE’s) are the numerically dominant type of estuary accounting for ≈ 70 % of all estuaries along the South African coastline. Despite their numerical dominance, aspects of the biology of organisms within these systems, particularly macrocrustacea remain poorly understood.

- Description: Mathematics and science form an integral part people’s daily lives. South African people suddenly find themselves on a technological highway, where mathematical, scientific and creative thinking as well as problem solving skills take centre stage. However many people fear these, and believe that they are unable to tackle them. Mathematics and science educators therefore have need to have knowledge and understanding regarding 6 the foundation of the teaching of these subjects in the intermediate and senior phases at schools. This should enable them to contribute positively towards changing people’s perceptions about these subjects. Based on the above information I felt it imperative for me to investigate the impact of shortages of maths and science educators with special reference to the Buffalo City Area. Purpose of the study: 1 To determine whether schools are able to attract and retain qualified maths and science educators, 2 To identify the quantity of quality maths and science learners schools are able to produce for tertiary education, 3 To investigate the rate of turnover of maths and science educators, 4 To identify the number of maths and science learners who are willing to study maths and science at tertiary level and thereafter join the teaching fraternity.
