- Description: This study was conducted in Grahamstown in the Eastern Cape, South Mrica. Triggered by the demands of South Mrican post-apartheid curriculum transformation, the study focused on establishing a sustainable science teachers' trans formative and continuous professional development (TTCPD) network with the view to improving their practice. It is premised on the assumption that teachers are capable of taking responsibility for their own professional development. It is a case study carried over a period offour years with a group of eight teachers. Rooted in the socially critical-emancipatory orientation in conjunction with the participatory action research approach, and located in the qualitative and interpretive research paradigms, it focuses on doing research in democratic and egalitarian ways through working with teachers rather than on them. Such a stance supposes a collaborative partnership and a dialogic relationship viewed as being both reciprocal and mutually enriching for the teachers who were seen as co-learners and co-researchers in this study. Two main goals of the study may be identified. For the first goal, the actors in this study established a sustainable and participative approach to professional development. This was explored through the formation of a TTCPD network which was informed by the actor-network theory framework. Our focus was on co-construction of scientific knowledge utilising the development and adaptation of learning and teaching support materials (LTSMs) as a catalyst to drive the process. The second goal was to examine how the TTCPD network enhanced the teachers' subject-content knowledge, pedagogical-content knowledge as well as individual and collaborative reflections. The research process evolved into three mam phases: The initial phase involved adapting and modifying LTSMs which were initially used in conjunction with microscale science kits and pilot tested with a group of Grade 10 students. This led to the second phase of the research project, which was aimed at gaining insights into the science teachers' capabilities in developing teaching and learning units of work. ii \ The second phase focused on the development of a collaborative orientation to the development of LTSMs and culminated in the formation of sub-networks responsible for certain tasks within the broader network. AB common ground, we focused on developing teaching and learning units of work on the following science topics: electrostatics, electricity, and electrochemistry, to illuminate and foster integration within science. The third phase was concerned with gaining insights into the science teachers' practice in their classrooms. This phase focused on putting theory into practice through the collaborative implementation of teaching and learning units of work. Feedback on the lessons was discussed during our workshops as an attempt to further enhance collaborative reflections. Data was generated usmg workshop discussions with reflective notes; active interviews; focus group discussions; co-teaching, participant observation and videotaped lessons with reflective notes; and a research journal. A variety of data generation techniques were employed to enhance validity and quality of the research. Techniques for validation and trustworthiness of data included triangulation; member checks orface validity; prolonged engagement; catalytic validity and peer validation. The study exposed the underlying historical, ideological and epistemological contradictions of the teachers' past educational backgrounds. It emerged that the ways in which they were taught were at times an inhibitor to innovativeness, perpetuating transmissive approaches to teaching and learning. Lack of professional development and support, and the tensions between policy formulation and implementation exacerbated this. Reflections from the teachers' experiences further revealed that, for teachers to be effective agents of change in the reform process, empowerment opportunities are vital. AB a result, exposure to the TTCPD network was useful in capacitating the teachers with the development of LTSMs, which led to the enhancement of their pedagogical, and science content knowledge conceptual development as well as collaborative reflections.The main findings of this study is that, science teachers' transformative and continuous professional development based on participative approaches and mutual collegial support are indispensable, and that teachers' socio-cultural contexts and experiences should be taken into consideration during this process. Teachers should be regarded as central in the process, and mutual respect and dialogical relationships are pivotal. A further recommendation of this study is that capacity-building is critical for quality teaching and learning, and there is a need to move beyond the rhetoric of complacency to pro-activism, supporting ongoing development of teachers in professional transformative networks. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The diet and growth of sharptooth catfish, Clarias gariepinus, in an oligotrophic system (Kat River Reservoir, Eastern Cape, South Africa) were compared to those in a eutrophic system (Laing Reservoir, Eastern Cape) to determine if the trophic status of a waterbody had an effect on the growth rate of the species. In order of importance, the diet of catfish in Kat River Reservoir consisted of fish, insects, zooplankton, plant material and other items, while the diet of catfish in Laing Reservoir consisted of fish, plant material, zooplankton, other vertebrates and insects. The diets of catfish in the two reservoirs had a similarity index of 68.1% and there was no significant difference in their nutritional value. Fish prey was the most important dietary component in both reservoirs. Temperature regime and zooplankton and zoobenthos density were similar in both systems. However, fish prey density was significantly higher in the eutrophic Laing Reservoir and catfish grew significantly faster in that system. The slower growth rate in Kat River Reservoir was attributed to the higher energy costs associated with the capture of fish prey, which was less abundant than in Laing Reservoir. Trophic status therefore had an indirect effect on catfish growth by influencing the availability of fish prey.

- Description: Estuaries are important in the life history and the maintenance of the diversity of coastal fish species because of their function as nursery areas for juveniles as well as feeding grounds for adults (Cyrus 1991). The dependence of many fish species on estuaries is well documented (e.g. Wallace et al. 1984, Lenanton and Potter 1987, Blaber et al. 1989, Whitfield 1990, Hoss and Thayer 1993). Spotted grunter Pomadasys commersonnii (Haemulidae) (Lacepède 1801) is an estuarine-dependent species which spawns in the KwaZulu-Natal inshore coastal waters, between August and December (Wallace 1975b, Wallace and van der Elst 1975, Harris and Cyrus 1997, 1999). The eggs and larvae are transported southwards by the Agulhas Current, and juveniles between 20 mm and 50 mm TL recruit into the KwaZulu-Natal and south-eastern Cape estuaries (Wallace and van der Elst 1975, Whitfield 1990). Juvenile spotted grunter make use of the abundant food resources in estuaries, where they grow rapidly and remain for a period of 1–3 years (Wallace and Schleyer 1979, Day et al. 1981). Upon attaining sexual maturity (at between 300 mm and 400 mm TL), they return to the marine environment (Wallace 1975b). Some adults, however, return to estuaries to feed and to regain condition after spawning (Wallace 1975b, Whitfield 1994). The return of post-spawning fish coincides with increased catches by fishers in estuaries between July and January. These events are known as ‘grunter runs’ (Wallace 1975a, Marais and Baird 1980, Marais 1988, Pradervand and Baird 2002). It is suggested that adults spend up to several months in estuaries, before moving back to sea where they undergo gonadal development and ultimately spawn (Wallace 1975b, Wallace and van der Elst 1975). It is believed that adult fish also enter estuaries in a prespawning state to gain condition en route to their spawning grounds in KwaZulu-Natal (Webb 2002).

- Description: Nathaniel Merriman’s lectures on Shakespeare were published in 1857 and 1858. The first, “On the Study of Shakspeare,” was delivered in the Court House, Grahamstown on the 2nd September 1857 to an audience of more than four hundred and fifty people. The second, “Shakspeare, as Bearing on English History,” was given in the same venue two months later, on Friday, 6 November 1857, and was also well attended. The lectures were published under the auspices of the Committee of “The General Institute,” which sponsored the lectures, and printed at the Anglo-African Office in the High Street. The two lectures and their context are little known in Shakespeare studies because the original pamphlets are rare. The first lecture appears in Mendelssohn’s South African Bibliography (1910), while the second is picked up only in the 1979 revision of that work. Copies of “On the Study of Shakspeare” are held by the Mendelssohn Library in the Library of Parliament, Cape Town; by The South African Library, Cape Town; and in the Oppenheimer Collection, Johannesburg. Copies of “Shakspeare, as Bearing on English History” are held by the Mendelssohn Library; by the University of the Witwatersrand Library, Johannesburg; and by the Kimberley Public Library. The purpose of preparing annotated editions of these lectures is to make them more accessible to scholars and draw them further into the mainstream of international discussion on colonial Shakespeare.

- Description: The biosorption of copper, nickel, gold and platinum from single metal aqueous solutions by the nickel hyperaccumulator Berkheya coddii plant biomass was investigated. Potentiometric titrations of the biomass and determination of optimal sorption pH for each metal showed that nickel ions were released from the biomass into solution. The presence of free nickel ions interfered with the uptake of the other three metals and further biosorption investigations were discontinued. Three fungal isolates found colonising metal solutions were cultured and screened for their ability to remove 50 mg.l⁻¹ of copper, nickel, gold and platinum from solution and to survive and grow in precious metal refinery wastewaters. One isolate was selected for further studies based on its superior metal uptake capabilities (35 and 39 mg.l⁻¹ of gold and platinum, respectively) and was identified as Phoma glomerata. Copper, nickel, gold and platinum uptake studies revealed that nickel and gold were the most toxic metal ions, however, toxicity was dependent on pH. At pH 6 more biomass growth was achieved than at lower pH values and metal uptake increased by 51 and 17 % for copper and nickel, respectively. In addition, the production of extracellular polymeric substances played a role in base metal interaction. Precious metals were observed to be preferentially removed from solution, complete removal of gold and platinum was observed at all initial pH values, 89 % of copper was bioaccumulated at an initial metal concentration of 55 mg.l⁻¹ (pH 6) and only 23 % of nickel was removed from solution under the same conditions. Metal bioaccumulation was confirmed through transmission electron microscopy and micro particle induced X-ray emission. The effect of P. glomerata immobilised in a packed bed reactor on precious metal refinery wastewaters was investigated. It was found that the fungal isolate was not able to remove the high salt and chemical oxygen demand concentrations found in the wastewaters, however due to its ability to survive and grow in undiluted wastewater and remove metal ions from solution it may be utilised as a metal detoxification step in the treatment process train. , PDFCreator Version 0.9.0 , AFPL Ghostscript 8.53

- Description: This thesis examines selected speculative novels by Margaret Atwood, Ursula K. Le Guin, Doris Lessing and Marge Piercy. It argues that a specifiable ecological ethic can be traced in their work – an ethic which is explored by them through the tensions between utopian and dystopian discourses. The first part of the thesis begins by theorising the concept of an ecological ethic of respect for the Other through current ecological philosophies, such as those developed by Val Plumwood. Thereafter, it contextualises the novels within the broader field of science fiction, and speculative fiction in particular, arguing that the shift from a critical utopian to a critical dystopian style evinces their changing treatment of this ecological ethic within their work. The remainder of the thesis is divided into two parts, each providing close readings of chosen novels in the light of this argument. Part Two provides a reading of Le Guin’s early Hainish novels, The Left Hand of Darkness, The Word for World is Forest and The Dispossessed, followed by an examination of Piercy’s Woman on the Edge of Time, Lessing’s The Marriages Between Zones Three, Four and Five, and Atwood’s The Handmaid’s Tale. The third, and final, part of the thesis consists of individual chapters analysing the later speculative novels of each author. Piercy’s He, She and It, Le Guin’s The Telling, and Atwood’s Oryx and Crake are all scrutinised, as are Lessing’s two recent ‘Ifrik’ novels. This thesis shows, then, that speculative fiction is able to realise through fiction many of the ideals of ecological thinkers. Furthermore, the increasing dystopianism of these novels reflects the greater urgency with which the problem of Othering needs to be addressed in the light of the present global ecological crisis.

- Description: The primary thesis of this dissertation is that the development of narrative strategy and technique through the course of Samuel Beckett’s fictional oeuvre enacts a parody of the Cartesian method of doubt, in which the search for first principles, instead of providing grounds for certainty, is a hopeless, grotesque quest for a self which eludes any and every assertion. My chief concerns are thus, firstly, to explicate and elucidate the nature of such narrative strategies and techniques, and how these can be said to parody epistemological procedure; and secondly, to interrogate the implications of this parody for the epistemological and interpretative endeavour of which the human sciences are comprised. These two issues are explored by way of an examination of Beckett’s earliest novel, Murphy, and the narrative impasse that arises from the contradiction between this work’s largely realist form and quasi-postmodern content. I thereafter argue that the later fiction, most particularly the Trilogy, achieves formal and stylistic solutions to the aesthetic and epistemological challenges raised by the earlier work. Beckett’s fictional oeuvre, I contend, can best be construed as an attempt to attain that which exceeds and escapes narrative in and through narrative, namely madness or death. The achievement of either would entail the obliteration of the possibility of narrating at all, and the novels, engaging in a self-deconstructing endeavour, thus occupy a profoundly paradoxical position. Any attempt to interpret a body of work of this nature can only respond in an analogous manner, by trying to make meaning of the subversion of meaning, and deconstructing the assumptions that inform its procedures. This dissertation argues that it is precisely in the way in which it necessitates such selfreflexive discursive analysis that the import of Samuel Beckett’s fiction lies, and extrapolates the significance of this for an understanding of discourse, literary criticism, and epistemological procedure.

- Description: The primary thesis of this dissertation is that the development of narrative strategy and technique through the course of Samuel Beckett’s fictional oeuvre enacts a parody of the Cartesian method of doubt, in which the search for first principles, instead of providing grounds for certainty, is a hopeless, grotesque quest for a self which eludes any and every assertion. My chief concerns are thus, firstly, to explicate and elucidate the nature of such narrative strategies and techniques, and how these can be said to parody epistemological procedure; and secondly, to interrogate the implications of this parody for the epistemological and interpretative endeavour of which the human sciences are comprised. These two issues are explored by way of an examination of Beckett’s earliest novel, Murphy, and the narrative impasse that arises from the contradiction between this work’s largely realist form and quasi-postmodern content.

- Description: This research investigates contemporary South African performance within the context of prominent social and cultural change following the political transition from an apartheid state to democracy. Specifically, it looks at the relationship between a popular comic variety show The Most Amazing Show (TMAS), and aspects of contemporary South African society and culture, particularly relating to prominent efforts to affect post-election transformation of South African society and culture through the construction of a South African 'rainbow nation'. By analysing TMAS in terms of broader historical, performative and discursive contexts, it engages a relational reading of the performance. The study argues that TMAS both challenges and participates in the manner in which rainbow nation discourse constructs South African society and culture. Firstly, it considers the performance's construction of hybrid South African identities, including white Afrikaans, white English and white masculine identities. It argues that these reconstructions undermine the tendency within rainbow nation discourse to construct cultural hybridity in terms of stereotypically distinct identities. Secondly, it considers TMAS' construction of collective experience and social integration, which subverts the often glamorised and superficial representations of social healing and integration that are constructed within rainbow nation discourse. The analysis makes prominent reference to the notion of 'liminality' in order to describe the manner in which TMAS constructs significance within the tension that it establishes between oppositional, and often contradictory, positions. Furthermore, it attempts to establish a link between this notion of liminality and notions of theatrical syncretism that are prominent in contemporary South African theatre scholarship, and emphasise processes of signification that are constantly shifting and unstable.

- Description: The issue of refugees in South Africa has come under the spotlight recently, particularly in the light of the xenophobic violence that swept the country in 2008. As a Baptist pastor, working in a congregation which has a vital ministry towards refugees, the writer became aware that only a handful of Baptist congregations in the Western Cape had a similar concern for refugees and asylum seekers. These observations raised the question of ministry to refugees on the part of Baptist churches in SA.

This dissertation seeks to provide such a biblical theology of ministry to refugees that can in turn provide a basis from which local congregation can develop such ministry. To provide the context of refugees in SA, this study begins by outlining the phenomenon of refugees in the context of SA, as well as the conditions experienced by refugees. This dissertation further seeks to delineate a number of Baptist principles that relate to the issue of Baptist churches and ministry to refugees.

- Description: Syntheses of Schiff bases were carried out by reacting salicylaldyhde, ortho-vanillin, para-vanillin or vanillin with aniline, 1-aminonaphthalene, 4- and 3-aminopyridine, and also with 2- and 3-aminomethylpyridine. The various Schiff bases obtained from the condensation reaction were reacted with CoCl₂.6H₂0, triethylamine stripped CoCl₂.6H₂0 or Co(CH₃COO)₂ to form cobalt(Il) complexes of ratio 2:1. The complexes obtained from cobalt chloride designated as the "A series" are of the general formulae ML₂X₂.nH₂0 , (L = Schiff base, X = chlorine) while those obtained from cobalt acetate or triethylamine stripped cobalt chloride denoted as "B" and C" are of the general formulae ML₂. nH₂0. The few complexes that do not follow the general formulae highlighted above are: IA [M(HL)₃.Cl₂], (L = N-phenylsalicylaldimine), 4A = (MLCl₂), (L = N-phenylvanaldiminato), 7 A and 21 A (ML₂), (L = N-naphthyl-o-vanaldiminato, and N-methy-2-pyridylsalicylaldiminato respectively), 8A = MLCI, (L = N-naphthylvanaldiminato), 12A = M₂L₃Cl₂, (L = N-4-pyridylvanaldiminato), 15A (MLCI), (L = N-3-pyridyl-o-vanaldiminato). The ligands and their complexes were characterized using elemental analyses and cobalt analysis using ICP, FT-IR spectroscopy (mid and far-IR), NIR-UV/vis (diffuse reflectance), UV/vis in an aprotic and a protic solvents, while mass spectrometry, ¹HNMR and ¹³CNMR, was used to further characterized the ligands. The tautomeric nature of the Schiff bases were determined by examining the behaviour of Schiff bases and their complexes in a protic (e.g. MeOH) and non-protic (e.g. DMF) polar solvents. The effects of solvents on the electronic behaviour of the compounds were also examined. Using CDCl₃, the NMR technique was further used to confirm the structures of the Schiff bases. The tentative geometry of the complexes was determined using the spectra information obtained from the far infrared and the diffuse reflectance spectroscopy. With few exceptions, most of the "A" series are tetrahedral or distorted tetrahedral, while the "B + C" are octahedral or pseudooctahedral. A small number of complexes are assigned square-planar geometry owing to the characteristic spectral behaviour shown. In order to determine their biological activity, two biological assay methods (antimicrobial testing and brine shrimp lethality assay) were used. Using disc method, the bacteriostatic and fungicidal activities of the various Schiff bases and their respective complexes to Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa as well as Aspergillus niger, were measured and the average inhibition zones are tabulated and analysed. Both the Schiff bases and their complexes showed varying bacteriostatic and fungicidal activity against the bacteria and fungus tested. The inhibition activity is concentration dependent and potential antibiotic and fungicides are identified. To determine the toxicity of the ligands and their corresponding cobalt(II) complexes, brine shrimp lethality assay was used. The LD₅₀ of the tested compounds were calculated and the results obtained were tabulated for comparison.

- Description: Falling within the ambit of the Department of English Literature but with interdisciplinary scope and method, the research undertaken in this thesis examines Michael Radford’s 2004 film production William Shakespeare’s The Merchant of Venice using the Book History approach to textual study. Previously applied almost exclusively to the study of books, Book History examines the text in terms of both its medium and its content, bringing together bibliographical, literary and historical approaches to the study of books within one theoretical paradigm. My research extends this interdisciplinary approach into the filmic medium by using a modified version of Robert Darnton’s “communication circuit” to examine the process of transmission of this Shakespearean film adaptation from creation to reception. The research is not intended as a complete Book History study and even less as a comprehensive investigation of William Shakespeare’s The Merchant of Venice. Rather, it uses a Shakespearean case study to bring together the two previously discrete fields of Book History and filmic investigation. Drawing on film studies, literary concepts, cultural and media studies, modern management theory as well as reception theories and with the use of both quantitative and qualitative data, I show Book History to be an eminently useful and constructive approach to the study of film.

- Description: Economic development remains elusive for many world economies, but especially those of African countries. The current global inequalities in terms of GNP per capita and human living standards between developed and developing nations have ensured that the challenges of food insecurities are only some of the many negative experiences of underdevelopment in the African continent. Hence, delivery pressures are increasing on policy makers and researchers to provide tangible and timely economic solutions to the resilient state of underdevelopment. In the policy fights against the challenges posed by a lack of development in South Africa, the agricultural sector has in the past and continues in the present to play a central role. Such is the case because the majority of citizens rely on agricultural production activities for their livelihoods. For instance, even though the sector only contributed four percent towards the national Gross Domestic Product in 2006, in the Eastern Cape Province, more than seventy percent of the total population resided in rural areas. Moreover, in 2004 more than sixty percent of the national formal and informal employment levels were found in the sector. These economic indicators do not only reinforce the assertions that high levels of geographical and sectoral inequalities exist in the country’s economy, but they also illustrate the importance of the agricultural sector in public policy attempts, which are aimed at achieving food security alongside long-term developmental objectives. Some economists, especially the proponents of institutionalism, have argued that most of the recommendations to public policy interventions from mainstream economic research endeavours are not adequately helpful. The recommendations generally lack well considered and socially effective ideas, mainly because there remains some level of ignorance about the impacts that institutions have on economic and social systems. Some argue that this ignorance is reflected in (flawed) hedonistic and rationalist assumptions made about economic actors and in the methodological thinking of many research designs and economic analyses. The misuse of formal tools and statistical methods, for example, are some of the important factors, which have led to failures of the discipline of economics to provide effective policy solutions to problems of underdevelopment and poverty, especially in poor country environments. The thesis, having taken account of the majority of criticisms levelled against the classical and new-classical economic schools of thought, argues that the discipline as a whole lacks a paradigmatic integration of institutional and new-classical economic perspectives to offer appropriate guidelines for a methodology aimed at achieving socially responsive research outputs. The lack of this integration has resulted in a skewed selection of methods by economists, which are employed in research without a supportive and in-depth understanding of institutional and social factors. To support the thesis, a more effective and integrated framework for economic research is developed and presented with case study illustrations in a cumulative manner. The 20th century history of agricultural policies in South Africa, the agricultural and institutional case studies from the Eastern Cape Province alongside reviews of other agricultural studies are all used in presenting a case for rigorous institutional investigations in general economic research. These are also used in developing the proposed integrated framework, which aims to give guidance in developing research methods, which are more socially responsive. Having shown the usefulness of the proposed research framework, the thesis recommends that public policy interventions (at national and local levels) should aim to eliminate all types of institutions which have high associated transactional costs. The interventions should also encourage the emergence and growth of the types of institutions, which present the lowest costs to initiatives of economic development. In the primary case studies from the Eastern Cape Province, the insecurity of land tenure and the various local initiatives of business ventures are highlighted as two examples of the types of institutions, which respectively present high and low transactional costs to local initiatives of agricultural and economic development.

- Description: The Printing and Packaging Industry in South Africa has become very competitive over the last decade. Imports and the move towards environmentally friendly packaging have put additional strain on certain sectors of this industry. EH Walton Packaging (Pty) Ltd is one of oldest converters in the industry, established in 1845, and has always been a leader with regards to new technology. It has grown from a small, family business to one of the biggest and most respected in South Africa, but it is still a private company. Due to the rapid growth the shareholders approved a multi-million rand expansion project in 2000. After completion the anticipated increase in shareholder value did not materialize, even though the production facility is always busy. The objective of this research study is to demonstrate to senior management that quality does not end with accreditation of ISO 9001:2000, but that total quality management is invaluable as a business strategy to reach world class manufacturing standards and to sustain organisational excellence. The research will investigate the origins and development of total quality management and world-class manufacturing and extract the most important elements that form the basis of sustainable competitiveness, as well as research done on the reasons why businesses fail. These elements will be further investigated, with special emphasis on the African/South African environment. Research showed that sustained excellence in business and quality is based on customer focus, guided by strategic planning, with leadership at the core, enhanced by philosophy, employee improvement and involvement, and quality assurance. Failure of achieving excellence is best summarized by Deming’s Seven Deadly Sins. The case study approach that was followed to determine the status of total quality elements within the company yielded contrasting results. A number of the “sins” were identified as present in the business strategy; levels of leadership varies from traditional Summary to high performance; understanding of where the company is heading is fragmented; there are no social programs in place and training only concentrates on apprenticeships and not on developing shop floor skills – to mention a few. Surprising is the world-class orientation with regards to customers; but again, this is contrasted with the lack of active customer satisfaction initiatives. The study concludes that although many negative aspects exist and that the prevailing culture does not appear to support change towards world-class growth, there is an element of positive energy among employees. Most of the employees who participated in the study believe that the company has a bright future. It is these attitudes that must be used to drive change, with a clear vision, good strategies and world-class leaders.

- Description: The Printing and Packaging Industry in South Africa has become very competitive over the last decade. Imports and the move towards environmentally friendly packaging have put additional strain on certain sectors of this industry. EH Walton Packaging (Pty) Ltd is one of oldest converters in the industry, established in 1845, and has always been a leader with regards to new technology. It has grown from a small, family business to one of the biggest and most respected in South Africa, but it is still a private company. Due to the rapid growth the shareholders approved a multi-million rand expansion project in 2000. After completion the anticipated increase in shareholder value did not materialize, even though the production facility is always busy. The objective of this research study is to demonstrate to senior management that quality does not end with accreditation of ISO 9001:2000, but that total quality management is invaluable as a business strategy to reach world class manufacturing standards and to sustain organisational excellence. The research will investigate the origins and development of total quality management and world-class manufacturing and extract the most important elements that form the basis of sustainable competitiveness, as well as research done on the reasons why businesses fail. These elements will be further investigated, with special emphasis on the African/South African environment. Research showed that sustained excellence in business and quality is based on customer focus, guided by strategic planning, with leadership at the core, enhanced by philosophy, employee improvement and involvement, and quality assurance. Failure of achieving excellence is best summarized by Deming’s Seven Deadly Sins. The case study approach that was followed to determine the status of total quality elements within the company yielded contrasting results. A number of the “sins” were identified as present in the business strategy; levels of leadership varies from traditional Summary to high performance; understanding of where the company is heading is fragmented; there are no social programs in place and training only concentrates on apprenticeships and not on developing shop floor skills – to mention a few.

- Description: The recruitment, enlistment and forceful conscription of children as soldiers is a cause for grave concern all over the world and most especially in Africa, where years of factional fighting, civil wars and cross border conflicts have raged, children and youth have been pulled into violence not only as victims, but also as perpetrators. The involvement of children in war posses a severe challenge to prevailing moral and legal norms of the conduct of modern warfare. A major problem and most controversial issue, among others, is on the age at which children should be eligible to become combatants. Children, who may be viewed as a valuable resource due to their often inherent malleability, wish to avenge family member(s) killed in war, sense of immunity to danger, and or feeling of power in participating in the violence. Can the use of children as soldiers be effectively regulated in Africa? All efforts to assist child soldiers in recovering from the devastating effects of wars often unwillingly helped promote the growing number of child soldiers. This is in part because wars are now more fought internally among rebel armies and factions vying for power with the government and thus enlist children into their various armies. The study comes to a conclusion that drastic steps need to be taken to ameliorate this unfortunate situation. This formed the basis of the recommendations offered in the thesis to assist the African continent.

- Description: South Africa's right to tax the income of a non-resident is determined in terms of the South African "source rules" established by court decisions in relation to the imposition of tax in terms of the Income Tax Act. Unless a non-resident's income is captured by the South African "source rules" (on the basis that hi slits income is derived from a South African source), South Africa would have no right to tax such income, even if such non-resident creates a permanent establishment in South Africa by performing business activities within South Africa which could be considered essential (but not dominant) in nature. In such scenario the activities performed by the non-resident in South Africa may utilise the natural resources and the infrastructure of South Africa, but the South African fiscus would be deprived of the right to any tax revenues attributable to the income produced partly by such activities within South Africa. The South African "source rules" refer only to the main or dominant activities giving rise to the income for the purpose of determining the source of such income (and accordingly the right to tax such income). On the other hand, the "permanent establishment rules" as set out under the Organisation for Economic Cooperation and Development Model Tax Convention on Income and on Capital refer to all the taxpayer's essential business activities for the purpose of determining whether or not such activities create a pennanent establishment. The result of the narrow nature of the South African "source rules" is that, under certain circumstances, the South African fiscus would not necessarily be granted the right to tax all income produced partly within South Africa. The research demonstrated that incorporating the principles underlying the "pennanent establishment rules" into South African legislation would be a reasonable and logical solution to the problem of detennining the source of income. In so doing, the South African "source rules" would determine the source of income, and consequently South Africa's taxing rights, with reference to the essential business activities giving rise to such income. In such case South Africa would be afforded the right to tax the income of a non-resident in the event that it performs any of its essential business activities within South Africa, albeit not the dominant or main activities giving rise to the income.

- Description: Labour law is a system of rules regulating the labour force in the society. These rules of labour are legal rules and are legally enforceable which means that if there is a breach of rules a party may approach a court of law or any other institution to obtain relief in respect of the breach of the rules. As a large percentage of the population at any given time in the world is involved with employment relationship, the labour relationships between employer and employee cannot be ignored as it affects both socio-economic and political factors in our society. Labour Law in general focuses on various relationships, including the relationship between the employer and employee, between the employer and a trade union or a group of employees, employers and employers’ organization. From the foregoing it can be deduced that there are two components of labour law which must be distinguished, namely individual and collective labour. The individual relationship focuses on the relationship between the employer and the employee while collective labour laws deal with matters such as legal nature of trade unions (and employers’ organization), the legal nature and enforceability of collective agreements, collective bargaining institutions and the legal consequences that flow from strikes, lock outs and other forms of industrial action. Collective labour law can therefore be said to be the body of rules which regulates the following collective relationships between: • employees and the trade union they belong to • employers and employers’ organization • employers and /or employers organization and trade unions • the government and trade unions • the government and employers organization However the collective labour law cannot be said to be absolute but is interdependent with individual labour law because the collectively agreed terms become part of the individual employment relation. This study mainly focuses on the collective labour aspect of the labour law system which shall be discussed in detail in the chapters to follow.

A comparison of the values of water inflows into selected South African estuaries : the Heuningnes, Kleinmond, Klein, Palmiet, Cefane, Kwelera and Haga-Haga

- Description: “An estuary is a partially or fully enclosed body of watera) which is open to the sea permanently or periodically; b) within which the sea water can be diluted, to an extent that is measurable, with freshwater drained from inland” (National Water Act, 1998). Estuaries are ecologically important because they are habitats for birds, fish and plants and they are valuable because they provide human beings with food (fish) and recreational pleasure in the form of unique views, bird watching and opportunities for swimming and boating. It is in this context that they may be said to provide economic goods and services for current and future generations. The provision of these services is dependent on the inflow of freshwater into estuaries. The problem with estuarine freshwater demand is that estuaries are the ‘last in line’, literally and perhaps in the typical prioritisation of human wants by government. Clearly it is imperative that the value of freshwater inflows into estuaries be determined and these values incorporated into catchment management decision making. South African estuaries have in the past mainly been managed on a piecemeal basissometimes in the interest of fishermen, sometimes property development owners and sometimes other local interest groups. This situation changed with the National Water Act of 1998. One of its objectives was to address the mismanagement and inadequate research about water inflow impacts on estuaries (Allanson and Baird, 1999). The global warming phenomenon is going to negatively affect estuaries and put more pressure on the availability of freshwater inflows into estuaries, as well as the availability of drinking water. The majority of South African estuaries are temporally open/closed and experiencing reduced functioning due to reductions of freshwater inflow to them. Given the overwhelming evidence available on the significance of freshwater inflow to estuary functionality, it is clear that an important component of catchment management is the allocation of river water into estuaries. Economic guidance comes in the form of comparisons of value. There are seven estuaries for which values were generated, the Heuningnes, Kleinmond, Klein, Palmiet, Cefane, Kwelera and Haga- Haga. All of the seven estuaries fall in areas characterized by warm temperate climates and low rainfall levels. Estuary services, like many other environmental services, are not traded in the markets. For this reason, in order to estimate their value, reference must be made to proxy markets, and methods of valuation have to be employed that can use proxy market information - like the contingent valuation method (CVM), the travel cost method (TCM) and the hedonic pricing method (HPM). For the purpose of this research the CVM was preferred because it is best suited to including passive or nonuse values. The CVM estimated values are compared with other values generated using the TCM. The information required to make the CVs was gathered through surveys in at the seven selected estuaries from December 2005 to April 2006. From this information sample mean and median Willingness to Pay (WTP) values for freshwater were calculated, socio economic profiles were generated, the importance that respondents attached to various activities in the estuary was deduced, and, Tobit and Ordinary Least Squares (OLS) statistics models were used to predict household WTP. The Total WTP (TWTP) for each estuary was obtained by multiplying the median WTP by the total number of households that use the estuary. The median WTP is preferred to the mean WTP because of a skewed bid distribution of WTP among the users. The value per m3 of freshwater was obtained by dividing the TWTP by the total forecast reduction in water inflows into the estuary.

- Description: Whole Body Vibration (WBV) training is a new addition to the field of Exercise and Sports Science and has been developed for the use in strength and conditioning exercises. With the introduction of this new mode of exercise, the study focused on comparing the strength gaining effect of WBV training versus conventional resistance training. The study was conducted in a descriptive, exploratory manner utilizing a quasi-experimental approach with a three group comparison pre-test-post-test design consisting of an experimental-, comparison- and control group. Convenience and snowball sampling were used to select 43 male and female healthy, sedentary volunteer participants. The research focused on reviewing the contribution that each mode of training offers to increase strength in the upper leg and underlines the important physiological adaptations that the human body undergoes to bring about an increase in muscle strength. Both the whole body vibration and land-based resistance groups trained three times a week over an eight week intervention period. Exercises were performed with progressive increments in the frequency, amplitude and duration for the WBV- and in workload, number of sets and repetitions for the conventional resistance training program. The control group remained sedentary throughout the duration of the study. The dependent variables of peak torque flexion and extension of the knee joint in both legs were analyzed using descriptive and inferential statistics. Analysis of covariance (ANCOVA) was done to determine intra-group differences. Post-hoc analysis in the form of Scheffé’s test was done to determine and compare inter-group differences. Practical significance was indicated by means of Partial eta2 The analysis of the results revealed significant strength increases in both conventional resistance training and WBV for most of the dependent variables, except for peak torque extension, where the WBV group did not increase significantly. Based on these results, it can be concluded that both modes of conventional resistance and whole body vibration increased selected dependent variables for upper leg strength in previously inactive individuals.

- Description: his study builds on South African cross-cultural research which demonstrated the importance of careful stratification of multicultural/multilingual normative samples for quality of education in respect of English and African language (predominantly Xhosa) speaking adults and children tested with the WAIS-III and WISC-IV, respectively. The aim of the present study was to produce an expanded set of preliminary comparative norms on the WISC-IV for white and coloured Afrikaans, white English and black Xhosa speaking Grade 7 children, aged 12 to 13 years, stratified for advantaged versus disadvantaged education. The results of this study replicate the findings of the prior South African cross-cultural studies in respect of quality of education, as groups with advantaged private/former Model C schooling outperformed those with disadvantaged former DET or HOR township schooling. Furthermore, a downward continuum of WISC-IV IQ test performance emerged as follows: 1) white English advantaged (high average), 2) white Afrikaans advantaged and black Xhosa advantaged (average), 3) coloured Afrikaans advantaged (below average), 4) black Xhosa disadvantaged (borderline), and 5) coloured Afrikaans disadvantaged (extremely low). The present study has demonstrated that while language and ethnic variables reveal subtle effects on IQ test performance, quality of education has the most significant effect – impacting significantly on verbal performance with this effect replicated in respect of the FSIQ. Therefore caution should be exercised in interpreting test results of individuals from different language/ethnic groups, and in particular those with disadvantaged schooling, as preliminary data suggest that these individuals achieve scores which are 20 – 35 points lower than the UK standardisation.

- Description: This thesis investigates the challenges facing developmental local government in South Africa, using the Nelson Mandela Metropolitan Municipality as a reference. The thesis comprises eight chapters. The study is based on the assumption that the Nelson Mandela Metropolitan Municipality, like other municipalities in South Africa, is confronted by numerous challenges in implementing its constitutional developmental mandate conferred on it by the Constitution of the Republic of South Africa Act 108 of 1996. It is vital that local government understands and contextualises these challenges, so that appropriate interventions may be developed. The widespread recent service delivery protests which, in many instances, have turned violent, have sounded an alarm that cannot be ignored. If local government is already struggling to fulfill its traditional mandate of service delivery, then it would find it difficult to spearhead social and economic transformation and development. This study proposes to provide a brief historical background on the evolution and transformation of local government in South Africa. Issues such as the new status and developmental mandate of local government, the extent to which local government has succeeded in complying with its developmental mandate, as well as the challenges it has encountered along the way, will be addressed. Recommendations are presented on how the existing status quo can be changed to enhance service delivery and development and enable low government to fulfil its developmental role more efficient and effectively, with particular reference to the Nelson Mandela Metropolitan Municipality. The empirical survey and research methodology employed in the study is described. This is followed by the operationalisation of the survey questionnaire used for gathering the data needed for analysis. The research findings of the empirical survey are then statistically analysed and reported. The concept of models is introduced, and selected models are explained. This is followed by an explanation of the proposed normative model for monitoring and evaluating service delivery and development in the Nelson Mandela Metropolitan Municipality, for possible replication in other South African municipalities. Various recommendations flowing from the results of the empirical study, namely the responses made by the respondents during the empirical survey, are proposed in the final chapter. If adopted, these recommendations will enable the Nelson Mandela Metropolitan Municipality to deal with the developmental challenges facing it, ultimately rendering the Municipality a more efficient and effective developmental agent.
