- Description: This research was concerned with investigating “the absence of Total Productive Maintenance (TPM)” at a plastic painting plant. TPM is a combination of operations and maintenance activities and is performed by operators under their own authority and is called “autonomous maintenances”. The author has tested the degree of implementation of TPM by using a sevenstep TPM implementation model this highlighted an absence of TPM in the organisation investigated. TPM is a relatively new concept in the South African automotive industry and has not been fully accepted by management as a solution to the maintenance problems in the organisation. Due to a long implementation period and the difficulty in measuring the benefits of the TPM program for the organisation TPM tends not to be implemented by companies. The research studies several maintenance philosophies each with its own advantages and disadvantages. The benefits that arise from the implementation of an effective TPM philosophy were explored. The development of an effective improved model for the implementation of TPM was investigated. Maintenance engineers and managers in any organisation can use this model to implement an effective TPM program. The seven-step TPM implementation model formed the basis for the compilation of a questionnaire. A survey was conducted to determine if an absence of TPM existed in a plastic painting plant. The results from the survey were drawn up and recommendations to further develop a model for the implementation of TPM was put forward.

- Description: The process of extradition is a vital component of International Criminal Law as a means of ensuring the suppression and prevention of international crimes. It is the internationally accepted method used by states to surrender an offender back to the state where the alleged offence was committed so that such offender can be tried and punished. Without such process, and with the ease of modern global travel, offenders would, in all likelihood be able to escape prosecution and punishment. Most organized democratic societies recognize that the suppression of crime is necessary for peace and order in society and that extradition is an effective tool to be used to bring to justice a fugitive attempting to evade the law by fleeing to another country. What follows is a discussion, firstly on the theory of extradition and secondly on the effect that human rights has had on the law of extradition. The theory of extradition involves an analysis of extradition from its ancient roots to its position in society today. With regard to extradition in South Africa, reference is made to the various periods of the country’s history. The colonial era before South Africa acquired Republican status in 1961 is referred to in order to establish a basis for the present law of extradition in South Africa. The period during the apartheid era after achieving Republican status in 1961 is discussed in order to show how and why South Africa moved away from its common law roots based on English Law. This era is also of importance as it led to the introduction of the present Extradition Act 67 of 1962. Finally the current position spanning from 1994 to the law as it stands in South Africa today, as influenced by the introduction of Constitutional law, is examined. The rule on non-inquiry is also examined in order to compare the traditional approach by states, where state sovereignty was of paramount importance, with the modern trend of emphasis being placed on fundamental human rights. The methods in terms of which extradition is accomplished, both in South Africa and internationally is also discussed. Such reference to the theory and nature of extradition is done to provide general background on the complex issue to be discussed. The crux of the treatise relates to the impact that the rise in status of fundamental human rights has had on the extradition process. Reference will be made to aspects relating to the protection of the offender’s procedural rights as well as to the protection of the individuals right to life, dignity and bodily integrity. Such examination will refer to the position in South African law as well as the position on the international front. Attention is given to developments in case law as well as to how the courts approach the tension between extradition and human rights both locally and internationally. Finally, in conclusion it is submitted that the extradition process is the most effective procedure available to return an offender to the state seeking his prosecution. The process has however, in modern times adapted to uphold the rights of the offender whose return is requested. This can be seen from the provisions included in recent treaties and conventions, most notably the European Convention on Extradition to which South Africa became a party in 2003. Extradition is clearly concerned with the balancing of the offender’s human rights and the need for effective enforcement of criminal law.

- Description: This research project investigates the implementation of formative assessment policies in the Life Science curriculum at two schools in the Keetmanshoop District, Karas Education Region. It takes the form of an interpretive case study and adopts a qualitative approach. Several data collection tools were used: classroom observation, document analysis and semi-structured interviews. Two of the eleven schools in the Karas Region offering Grade 10 Life Science were selected for the study, and the research participants at each school consisted of one Grade 10 Life Science teacher and five of their learners. The study situates itself in the context of Namibian educational reform by reviewing relevant literature pertaining to learner-centred (constructivist) education and assessment practices in pre- and post-independent Namibia. The study highlights issues pertaining to formative assessment that are at variance with reform policies, identifying six recurring themes that explain how formative assessment policies are implemented. These are teachers' perceptions of formative assessment and its role in teaching and learning, the type of learning being developed, marking/assessing assessment tasks, the integration of formative assessment into classroom instruction, strategies teachers used to implement formative assessment, and types and purpose of activities. The themes that evolved during the data gathering process provide insight into the ways in which teachers perceive formative assessment in relation to the ideals of Namibian educational reform policies. In the light of these findings, the study makes recommendations concerning the implementation of formative assessment policies so as to render these congruent with the theory underpinning leamer-centred education.

- Description: Indigenous forests and savannas, along with plantation forests, offer numerous benefits to rural communities and society at large. Yet, the role of forests and forestry in contributing to sustainable livelihoods and poverty alleviation are widely debated. However, much of the debate pertains to lessons from the humid tropics, with little consideration of the widespread dry forests and savannas. This paper considers the role of dry forest types, including savannas, using South Africa as a case example. It concludes that a large proportion of the population makes use of forests and the resources from them. These are vital components of local livelihoods, which probably prevent people from slipping into deeper poverty. Moreover, for a measurable proportion, engagement in informal forest activities, as well as the formal forestry sector, has resulted in them being able to move out of poverty. Additionally, the generally dry nature of forests in South Africa, coupled with the high unemployment rate, limit the extent of alternative locally based livelihood options, thereby magnifying the contributions from forests and forest products. The depressing effects of widespread HIV/AIDS on labour availability, economic activities and livelihoods has exacerbated peoples' dependence on forest products.

- Description: In Kenya, like in many developing countries, Micro and Small Enterprises (MSEs) have become the main focus for achieving the much-needed social and economic development and alleviating poverty. However, their development has been hampered by lack of access to appropriate financial and related services. Micro financing has been seen as a viable alternative to providing financial services to entrepreneurs in the MSE sector. The focus of this study was to explore the role of MFIs in the development of MSEs and to see if there are ways in which this role can be enhanced to better support the growth of MSEs. Such enhancement would contribute greatly towards government efforts to foster social-economic development. The results of the research indicate that generally, MFIs appear to have positively influenced the growth of MSE in Kenya and have potential to further influence MSE growth. There were however a number areas that if paid attention to could enhance this influence. These include the need for MFIs to offer supportive services as opposed to merely credit facilities to MSEs and the need for government intervention by putting in place a suitable Act to regulate the operations of MFIs.

- Description: Healthcare today has become a competitive industry, not only locally, but on a global level as well. In the South African economy the healthcare sector presently offers healthcare seekers two options to satisfy their healthcare needs – either through private business enterprises in the private sector or public enterprises in the public sector. Likewise, in the healthcare sector's hospital environment, patients can receive treatment from either private or public hospitals. As private business enterprises offering a relatively 'pure', but generally unsought-after service, private hospitals compete aggressively to attract patients. Patients are a hospital's lifeblood and they rightfully expect a high standard of customer service throughout the stay. With today's consumers being better informed, more sophisticated and more demanding than in the past, experts agree that the key to survival in the service industry today, almost without exception, is the quality of the service. The cornerstone of the service industry is without doubt the ability to deliver superior service quality that results in customer satisfaction. And the healthcare industry is no exception. Most consumers will experience a need for healthcare services at some time in their lives, but in South Africa, escalating medical costs in general and private hospitals in particular, have made private healthcare increasingly more expensive for the majority of the country's healthcare seekers. This situation raises the question of customer service in the private hospital industry and how patients' perceive service quality and evaluate customer satisfaction after a hospital stay. There is a growing body of empirical evidence from United States studies to show that service quality and customer (patient) satisfaction positively influence patients' behavioural intentions to reuse the hospital or recommend it to others (word-of-mouth endorsements). However, in South Africa, empirical studies to investigate these relationships have not been adequately addressed. This study was therefore an attempt to address the lack of scientific evidence and debate in the area of patient satisfaction. Against this background, the primary objective of this study was to measure patients' perceptions of service quality and customer satisfaction with a private hospital experience and to estimate the effect that each of these constructs will have on future behavioural intentions. More specifically, the present study was an attempt to assess empirically the most important dimensions of service quality and transaction-specific customer satisfaction dimensions that drive both patient loyalty and ‘overall’ or cumulative satisfaction in the South African private hospital industry. For the purpose of this study, buying intentions was used as a surrogate measure of loyalty as measured by willingness to reuse the hospital and/or willingness to recommend it to others (word-of-mouth endorsements). Initial exploratory research was conducted with the aim of assessing the views of three private hospital stakeholder groups, namely former patients, doctors and management about what the quality of service and customer satisfaction meant to each individual interviewed. A service enterprise that specialises in patient satisfaction surveys in the US provided particularly useful information during this phase of the study. Several case studies of patient satisfaction programmes, mostly at US hospitals, provided additional insights in this area. The study was conducted nationally at private hospitals owned by one of South Africa's three major hospital groups. Five private hospitals in four major centres were selected on a non-probability convenience basis to participate in the study. The hospital group's senior management and the management at each selected hospital gave their full commitment to ensure that the survey was successfully conducted in their hospital wards. Data were collected by means of a quantitative study using a selfadministered, structured questionnaire. Patients had to meet certain qualifying criteria which included being of adult age, in the hospital for an operation and at least one overnight stay. A total of 3 800 questionnaires was distributed to patients on a random basis in selected wards at the five hospitals by senior hospital staff designated for this task. From this distribution, 425 questionnaires were returned of which a final sample of 323 could be statistically analysed. To confirm the internal reliability of the measuring instrument, Cronbach alpha coefficients were calculated for each of the factors identified by the exploratory factor analysis. In order to assess the discriminant validity of the measuring instrument used to measure both service quality and customer satisfaction, the items were subjected to an exploratory factor analysis. The factors that emerged after the exploratory factor analysis were then used as independent variables in the four subsequent multiple regression analyses to assess the study's four hypothesised relationships. The findings revealed that the service quality dimensions that impact positively on both loyalty and cumulative satisfaction are Empathy of nursing staff and Assurance. The customer satisfaction dimensions to impact positively on both loyalty and cumulative satisfaction are Satisfaction with the nursing staff, Satisfaction with meals, and Satisfaction with fees charged.

- Description: School vandalism is a serious problem in South Africa, particularly, as it places a heavy burden on education budgets. It could also cause learning to collapse, since it infringes on the right of learners to be taught in clean, well kept school buildings, and to develop their full potential. It is generally accepted that cared for school facilities, adequate furniture and equipment, as well as clean ablution facilities, are conducive to a healthy learning environment. The aim of this research was to determine whether vandalism at schools in Nelson Mandela Metropole (NMM) has an influence on learners’ scholastic achievement. Against the background of the literature review, this investigation endeavours to report on the nature and extent of vandalism at a sample of South African schools, as well as preventative measures that be introduced to combat such vandalism. The research comprised of a study of relevant literature, followed by a qualitative research design. The literature study covered aspects regarding the nature, extent and consequences of vandalism at schools. The sample group consisted of learners, teachers and parents from four secondary schools in the western region of the Uitenhage District. The respondents completed questionnaires regarding their viewpoints on the role that the school, the parents, the community, the police and the media could play in curbing acts of vandalism at schools. The respective principals and some members of staff were also interviewed. The research revealed that both teachers and learners were of the opinion that preventative measures need to be put in place to combat the scourge of vandalism at schools. However, such programmes should be implemented in collaboration with the community, the parents, the South African Police Services and the media. In conclusion some recommendations were made to combat the scourge of vandalism at schools and these may be of value to all schools in South Africa that experience similar problems.

- Description: Substitute care is a temporary or permanent placement of children under the supervision of an adult person due to the absence of their biological parents. The escalating divorce rate, increase in extramarital births, high incidence of family violence, the growing number of children orphaned by HIV/AIDS, and the increasing career-orientatedness of parents have led to the development of diverse family structures. Grandparents and other family members are increasingly becoming the primary caretakers for children. Whilst it is generally assumed by society that children’s well-being is better served when they are raised by their biological parents, the purpose of this study is to: • explore what influence substitute care has on learners’ motivation; • formulate guidelines and recommendations for educators to improve the current levels of motivation of learners in substitute care. The literature related to substitute care and motivation were reviewed, with the aim of providing a firm theoretical basis for the study. Concepts related to motivation discussed, included types of and sources of motivation. Concepts related to the second focus of this study included forms of substitute care. Motivational theories related to this study were briefly discussed, namely: the Attribution Theory, the Drive Theory, Goal Theory, and the Self-worth and Selfefficacy Theories. Factors that have a motivational influence on learners, such as acceptance versus rejection, praise versus criticism, success versus failure and positive self-concept versus negative self-concept, were also discussed. A link was then drawn between motivation and substitute care. ii The research design chosen for this study can be described as qualitative, interpretive and constructive in nature. The research study was conducted in two phases: Phase One provided an investigation of the research problem by means of the following open-ended question: What is the influence or impact of your status as a child in substitute care on your motivation? Data were collected by means of eleven unstructured, in-depth personal interviews. Purposeful sampling was undertaken, which included high school learners all in substitute care. Data were analysed, as proposed by the eight steps of Tesch. Discussions between the observer, moderator and an independent re-coder took place to determine the final results of the research through a consensus principle. Key and related concepts were clustered together to formulate themes, categories and sub-categories. The following three themes emerged, based on the results of the data analysis. I. Problems in the close family circle have profound effects on learner motivation. II. Certain motivating forces help learners in substitute care to cope. III. Substitute care does influence learner motivation. Phase Two offered recommendations, derived from the findings of Phase One, to empower teachers in effectively supporting and motivating learners in substitute care. The conclusion was reached that substitute care does have an influence on the motivation of learners. This motivation can either be positive, which means encouraging learners towards their goal, or negative, which implies that it moves learners away from their goal.

- Description: This small scale exploratory research project investigated the grounding of rational number concepts in informal, everyday life situations. A qualitative approach was taken to allow for the identification and then in depth investigation, of issues of importance for such a grounding of rational number understanding. The methodology followed could be seen as a combination of grounded theory and developmental research. And the data was generated through in-depth and clinical interviews structured around a number of grounded tasks related to rational numbers. The research comprised three cycles of interviews that were transcribed and then analysed in detail, interspersed with periods of reading and reflection. The pilot cycle involved a single grade three teacher, the second cycle involved 2 grade three teachers and the third cycle involved 2 grade three children. The research identified a number of different perspectives that were all important for the development of a fundamental intuitive understanding that could be considered personally meaningful to the individual concerned and relevant to the development of rational number concepts. Firstly in order to motivate and engage the child on a personal level the grounding situation needed to be seen as personally significant by the child. Secondly, coordinating operations provided a means of developing a fundamental intuitive understanding, through coordination with affording structures of the situation that are relevant to rational numbers. Finally, goal directed actions that are deliberately structured to achieve explicit goals in a situation are important for the development of more explicit concepts and skills fundamental for rational number understanding. Different explicit structures give rise to different interpretations of rational numbers in grounding situations. In addition to these perspectives, it became evident that building and learning representations was important for developing a more particularly mathematical understanding, based on the fundamental understanding derived from the child's grounded experience. The conclusion drawn in this research as a result of this complexity, is that to achieve a comprehensive and meaningful grounding, children's learning of rational numbers will not follow a simple linear trajectory. Rather this process forms a web of learning, threading coordinating operations for intuitive development, interpretations for explicit grounding and representations to develop more formal mathematical conceptions.

- Description: The reduction of osmium tetroxide by a series of alcohols was studied spectrophotometrically. The reaction was observed to occur in two steps, unlike previously reported studies on this reaction. The identities of both reactants and products were established via a range of techniques. Equilibrium and kinetic data were gathered and reaction models were evaluated using equilibrium and kinetic modelling software. The following complexation reaction model emerged that simulates both the equilibrium and kinetic data. Os(VIII) + RCH2OHOs(VI) + RCHO2 Os(VIII) + Os(VI)k+2k1Complexk-2 Conditional rate constants and equilibrium constants were generated. Rate constants for the alcohol reactions were correlated with the Taft σ* constant. The ρ* value obtained (-1.4) is consistent with a hydride transfer mechanism coupled with synchronous removal of the hydroxyl proton. The identity of the osmium(VIII)-osmium(VI) complex has been suggested. Thermodynamic parameters were also reported. The rate constants for benzyl alcohol and 2-chloroethanol deviated from those predicted by the Taft plot. An explanation of enhanced resonance effects is offered for benzyl alcohol and an alternative reaction mechanism, involving proton abstraction, is offered for 2-chloroethanol. The reaction of the oxidation products of alcohols, namely ketones, with osmium tetroxide produced rate constants that were, perhaps surprisingly, far larger than those of the alcohols. A reaction mechanism for the oxidation of the ketones is suggested, which involves the enolate ion as the reactive starting reagent.

- Description: The crime of in-transit robbery is a sub-specie of the common law crime of robbery, which in essence is a crime of theft with violence. Robbery had evolved from begging, where beggars would harass their victims for money or items of value and then elevating their begging efforts to threats of violence, and in certain instances the usage of physical violence to solicit alms. As soon as road transport became prominent in society, the incidence of in-transit robbery increased where violence was used to overcome any form of resistance from the victim. During sea-faring transportation, piracy occurred using similar methods of violence to obtain goods from victims. In-transit robbery has undergone many changes in terms of modus operandi. From the early days of violent begging during the Roman Empire it has now become a greed driven, carefully planned crime, which is executed with military precision with high technology weapons of war. Robbery has advanced in judicial terms from a non-codified crime to a specific defined crime which carries prescribed minimum sentencing as punishment. , Abstract

- Description: Immovable asset management is the key element in enabling better service delivery by the national government. An improvement in the management of government’s immovable assets is required in South Africa to ensure that assets are optimally utilised for service delivery. The entire research attests to the importance of excellent management of government immovable assets throughout its life cycle within a framework of cost effectiveness, efficiency and reduced risk. The study discusses three technical challenges which comprise the incompleteness of the asset register, immovable asset life cycle management, a lack of implementation of the immovable asset management plan, the asset performance measures and standards for the immovable assets. The National Department of Public Works was targeted as a potential candidate to participate in this research. Primary data was collected through questionnaires and interviews to reveal the strengths and weaknesses and to develop the current theories and models. Secondary data was collected from books, journals, internet and conference papers. The asset management branch in the department was formed recently. The results of the research indicated that the asset management frameworks and the immovable asset management plans are not implemented as designed and there is no integration between the asset’s life cycle processes. The corrosion of information in the asset register was because of a lack of asset-computerized systems, competent personnel and adequate skills. In conclusion, immovable assets should be managed through integrated life cycle processes, policies and procedural documents should be developed and planning is important to the management of immovable assets. The asset register should work as a basic system for the management of immovable assets.

- Description: Cyclic dipeptides are widely used as models for larger peptides because of their simplicity and limited conformational freedom. Some cyclic dipeptides have been shown to produce antiviral, antibiotic and anti-tumour activity (Milne et al., 1998). In this study the cyclic dipeptides, cyclo(Ser-Ser) and cyclo(Ser-Tyr), were synthesised from their corresponding linear precursors using a modified phenolinduced cyclisation procedure. The phenol-induced cyclisation procedure resulted in good yields and purity of the cyclic dipeptides. Quantitative analysis and evaluation of the physicochemical properties of the cyclic dipeptides was achieved by using high-performance liquid chromatography, scanning electron microscopy, thermal analysis and X-ray powder diffraction. The structures of the synthesised cyclic dipeptides were elucidated using infrared spectroscopy, mass spectrometry, nuclear magnetic resonance spectroscopy and molecular modelling. The study aimed to determine the biological activity of cyclo(Ser-Ser) and cyclo(Ser-Tyr) with respect to their anticancer, antimicrobial, haematological and cardiac effects. Anticancer studies revealed that cyclo(Ser-Ser) and cyclo(Ser- Tyr) inhibited the growth of HeLa (cervical cancer), HT-29 (colon cancer) and MCF (breast cancer) cancer cell lines. Both cyclic dipeptides also inhibited the growth of certain selected Gram-positive, Gram-negative and fungal microorganisms in the antimicrobial study. Although the inhibition of growth in the anticancer and antimicrobial studies was statistically significant, the clinical relevance is questionable, since the inhibition produced by both cyclic dipeptides was very limited compared to other pre-existing anticancer and antimicrobial agents. Cyclo(Ser-Tyr) exhibited significant activity in the haematological studies, where it increased the rate of calcium induced-coagulation, and decreased the rate of streptokinase-induced fibrinolysis. Both cyclic dipeptides, however, failed to produce any significant effects on thrombin-substrate binding and ADPinduced platelet aggregation. Cardiac studies revealed that cyclo(Ser-Ser) and especially cyclo(Ser-Tyr) reduced the heart rate, coronary flow rate and ventricular pressure of isolated rat hearts.

- Description: Acid mine drainage is a well known environmental pollutant, not only in South Africa, but throughout the world, and the use of microbial processes in the treatment of these wastes has been the subject of investigation over past decades. Lignocellulose packed-bed reactors have been used in passive treatment systems, and, although effective initially, they show early decline in performance while the packing material remains largely un-utilized. Little is known about this phenomenon which remains a severe constraint in the development of efficient passive mine water treatment systems. It has been proposed that the degradation pathways of the complex lignocellulose substrate may be limited in some way in these systems during the manifestation of this effect. This study has addressed the problem using a molecular microbial ecology methodology in an attempt to relate trophic functions of the microbial population to the physico-chemical data of the system. A field-scale lignocellulose packed-bed reactor located at Vryheid Coronation Colliery (Northern Kwa-Zulu Natal province, South Africa) was monitored for six years and the results showed the classic profile of performance decline related to a slowdown in sulphate reduction and alkalinity production. The reactor was decommissioned , comprehensive samples were collected along the depth profile and the microbial populations investigated by means of 16S rRNA gene methodology. The population was found to include cellulolytic Clostridia spp., CytophagaIFlavobacterlBacteroidetes, Sphingomonadaceae and as yet uncultured microorganisms related to microbiota identified in the rumen and termite gut. These are all known to be involved as primary fermenters of cellulose. Oesulphosporosinus was present as sulphate reducer. A comparison of substrata sampling and population distribution suggested that spatial and temporal gradients within the system may become established over the course of its operation. Based on these findings, a laboratory-scale reactor was constructed to simulate the performance of the packed-bed reactor under controlled experimental conditions. The laboratory-scale reactor was operated for 273 days and showed comparable performance to that in the field in both biomolecular and physicochemical data. Clearly defined trophic niches were observed. These results suggested that a sequence of events does occur in lignocellulose degradation over time. Based on the spatial and temporal column studies, a descriptive model was proposed to account for these events. It was found that fermentative organisms predominate in the inlet zone of the system using easily extractable compounds from the wood, thus providing feedstock for sulphate reduction occurring in the succeeding compartments. Production of sulphide and alkalinity appears to be involved in the enhancement of lignin degradation and this, in turn, appears to enhance access to the cellulose fraction. However, once the readily extractables are exhausted, the decline in sulphide and alkalinity production leads inexorably to a decline in the overall performance of the system as a sulphate reducing unit operation. These observations led to the proposal that with the addition of a limited amount of a readily available carbon source, such as molasses, in the initial zone of the the reactor, the ongoing generation of sulphide would be sustained and this in turn would sustain the microbial attack on the lignocellulose complex. This proposal was tested in scale-up studies and positive results indicate that the descriptive model may, to some extent, provide an account of events occurring in these systems. The work on sustaining lignocellulose degradation through the maintenance of sulphate reduction in the initial stages of the reactor flow path has led to the development of the Degrading Packed-bed Reactor concept and that, has subsequently been successfully evaluated in the field.

- Description: This thesis presents a history of the landscape of Nqabara, an administrative area in a rural and coastal area of the Eastern Cape Province, South Africa. In the process of investigating landscape history, the inquiry engages with a range of data sources from diverging discursive contexts, including data from ethnographic fieldwork, from the consultation of archival documents and historical reports as well as from comparative historic and ethnographic research, necessitating a critical consideration of the epistemological contexts of data production and the dialogue between researcher and data. Furthermore, in its aim to move beyond historical description towards explanation, the study interrogates the dualist ontological conceptualisations of nature and culture, society and ecology, object and meaning upon which are built three dominant conceptual frameworks concerned with human-environment relationships: social-ecological systems theory, transdisciplinary landscape studies and political ecology. Drawing primarily upon the works of James Gibson, Anthony Giddens and Tim Ingold, an ontological foundation is developed to guide the enquiry and move towards an alternative understanding of the relationship of people’s livelihoods with respect to the landscape in which it is lived, which I call here the praxisembodiment perspective. This ontology takes the situated patterns of action of a situated agent-in-its-environment as its point of departure and proceeds to develop a framework explaining how relations among the patterns of action of different agents-in-their-environment, emerge in structures that simultaneously enable and constrain future action. The foundation is thereby provided for a monist understanding of how landscape and social structure emerge simultaneously from the complex intersection of patterns of actions and interactions of agents in their environment. This framework calls for an understanding of time, space and scale, not as independent variables influencing process and action, but as emergent properties arising from the patterns of actions of situated agents. Finally the alternative ontology is applied to the history of landscape and livelihoods of people of Nqabara. It is concluded that an appropriate understanding and explanation of the critical transformations in the landscape as well as in social institutions, should be sought through analysis of the complex ways in which patterns of action of multiple spatial and temporal rhythms and between multiple agents in an environment, intersect and resonate.

- Description: Despite the current widespread implementation of inclusive education into the South African educational system, it appears that little, if any, studies have been undertaken as to whether South African educators are adequately equipped to manage the changes that will be required with the implementation of this new approach to education. More specifically, whether our educators would be more aptly prepared for the many adaptations should they be in possession of a remedial qualification. This study is aimed at providing a detailed account of the implications of introducing inclusive education into the South African school system, with particular focus being placed on learners who present with barriers to learning as well as the essential curriculum, classroom and teaching adjustments required in order for these learners to reach their full potential within a mainstream classroom environment. The sample for this study firstly comprised of educators’ perceptions regarding their capabilities in coping with the demands of inclusive education. The viewpoints of 122 educators, within the Nelson Mandela Metropolitan area of the Eastern Cape, were recorded through the completion of individual questionnaires and interviews. Secondly, the files of 111 learners, from a remedial practice, who presented with barriers to learning were analysed to determine the effectiveness of appropriate remedial intervention in overcoming the respective barriers. The major findings of the present study were as follows: Many classroom modifications, changes in teaching styles and curriculum adaptations would have to be implemented to adjust to the demands of inclusive education; Educators would have to be trained regarding the different categories of learners with barriers to learning and their special educational needs; The majority of Eastern Cape educators do not feel suitably qualified to cope with the demands of inclusive education; Educators in positions of authority (principals, deputy principals and heads of department) indicated their inadequacies regarding coping and assisting parents and fellow educators with the demands of inclusive education; A large percentage of the responding educators indicated that they would be better suited to cope with the demands of inclusive education with a remedial qualification and were prepared to register at a tertiary institution to obtain such a qualification depending on certain incentives offered by the Education Department. In view of the findings of this study, recommendations have been made to enhance the current qualification levels of educators, to specifically include a remedial qualification, of which guidelines have been provided. This approach should vastly assist educators in coping with the demands of inclusive education and will ensure that they are suitably empowered to meet the needs of learners with barriers, who have been thrust into this system. Guidelines are also offered for a proposed remedial course that could be offered to education students as well as to those educators who are presently in the employ of the Education Department.

- Description: In contrast to many other African countries, inland fisheries in South Africa are poorly developed and the fish populations in many of the country’s 3 000 major dams are under-utilised. While the primary purpose South Africa’s dams is to supply water for domestic and agricultural use, there has been an increasing realisation that their fish populations could make a contribution to food security through the establishment of capture fisheries. Historically, the fish in most South African dams have primarily been utilised for recreational fishing purposes, as subsistence use was criminalised by the apartheid regime in all waters except in the former homeland areas. This legacy persists as many of South Africa’s rural communities do not have a fishing tradition and there is a lack of an institutional framework to facilitate managed and sustainable access to the fish resource in inland waters. Current utilisation of many inland dams is often complicated by the existence of multiple authorities and interest groups, often with competing agendas. As a result, the economic potential of these water bodies is unknown and often grossly underutilised. Our study outlines a case study of fisheries resources in the North West Province of South Africa that could be used for the creation of income and food security for local communities through the development of subsistence, commercial, and recreational fisheries. The study identifies the lack of guidelines for the development of inland fisheries and the lack of an inland fisheries policy, both at the provincial and national level, as major bottlenecks for the sustainable development of these resources and outlines possible focal areas for intervention.

The origins, developments, and current performance practices of African neo-traditional choral music of Southern Africa

- Description: This study deals with African neo-traditional choral music of sub-Saharan- and Southern Africa, with specific reference to extemporisation. The research focussed on the evolution of this music through an amalgamation of western choral music and African indigenous and traditional musical practices of sub- Saharan and Southern Africa. Specific reference to the syncretism of western music, which came to Africa through colonisation, and the way African indigenous musical traditions influenced it, is preceded by descriptions on African indigenous musical practices and western choral music traditions. The incorporation of traditional folk songs into African makwaya, or “choir music”, was inevitable. This development saw the birth of African neotraditional choral music as a formal part of many choirs’ programmes. A description of five sample choirs engaging with this music was followed by a case study on the Drakensberg Boys’ Choir. The way these choirs deal with different aspects regarding the preparation and performance of this music highlighted many parallels with African indigenous traditions. It also emphasises the important role of this music in choral performance, as well as choral education. As a genre in evolution, one aspect of this music, namely extemporisation, was studied in more detail in order to suggest another way of engaging with this music. Not only is choral extemporisation a possibility in African neo-traditional choral music of Southern Africa, but it is also a flourishing art form in Scandinavia. In Norway and Sweden it also utilises characteristics and techniques of folk music, which raised the status of this music to be a major art form. This notion prompted the suggested application of choral extemporisation to African neo-traditional choral music of Southern Africa. Even if any method of extemporisation may be utilised, it is proposed that characteristics of African sub- Saharan- and Southern African indigenous music be applied. This may result in the incorporation of more of these African indigenous elements in the neo-traditional choral music discussed than the current western harmonic emphasis. However, the suggestion is seen as a next step in the evolution of this music, which corresponds with international practices, and not to return to indigenous practices as such.

- Description: Stormwater attenuation policy has, over recent years, become a highly contentious issue for the property development community. Increased urbanisation, locally and internationally, has forced municipal authorities to reconsider the role of stormwater management in this evolving urban landscape. It is within this context that the legislative support and municipal policy for stormwater management in the City of Johannesburg has been explored, particularly in terms of the economic impact on property developers. The research aimed to explore the relationship between stormwater attenuation policy and the economic impact thereof on private property developers. Consideration was given to the cost, risk and time factors of legislative and policy requirements within the development process. Further consideration was given to the physical environment that has brought about current pressures. Based upon research of international issues highlighted in countries with well developed attenuation policy, a questionnaire was constructed to evaluate the response of local private property developers to selected issues as key sub-problems. The responses were tested against the developed set of hypotheses. The research indicated that developers had a generally poor level of knowledge with regard to the stormwater management policy of the City of Johannesburg, as well as the supporting legislative requirements of provincial and national policy documents. The results of the survey also indicated that developers were strongly opposed to the loss of developable area, but indicated a limited financial impact of the current stormwater attenuation policy. The risk inherent in incorporating an attenuation facility within a development was identified as being low with little perceived impact. Developers further indicated that the inclusion of attenuation facilities was seen as a significant contributing factor in the delay, approval and acceptance of new developments in which attenuation facilities were required, while maintenance costs were indicated to be of a low level of importance. Recommendations in response to the research findings included the establishment of detailed policy documentation and support for effective distribution channels in conjunction with industry and public focused information campaigns, improved municipal capacity and a greater level of technical support. A need for additional stormwater research and an increase in the capture of relevant data for GIS purposes was identified.
