- Description: Since the twentieth century, protected areas, usually in the form of nature reserves or national parks, have become increasingly more dominant as an international conservation strategy. An important factor in protected area management is the relationship between protected areas and its surrounding communities. Historically, the fortress conservation model based on the exclusion of human use and occupation prevailed in relation to protected areas. It is known that this approach brought with it many social and environmental injustices to local communities living in or adjacent to parks. However, a shift in conservation thinking occurred towards the end of the twentieth century, where it has increasingly been advocated for a more participatory approach in protected area management. South Africa has signed the international Convention on Biological Diversity that promotes a participatory approach to nature conservation, which is also reflected in the country’s national laws and policies. In relation to the literature and the lens of political ecology, this thesis sets out to assess in what ways and to what extent the participatory approach has been embraced by South Africa’s conservation authorities. As a case study, it looks at the Tsitsikamma National P ark ( incorporated into the larger Garden Route National Park). In order to get insight on h ow the participatory approach plays itself out at the T NP and what the nature of local communities’ relationship with the park is, this study looks at the aspects of (1) local communities’ socio-economic conditions, (2) their relationship with their natural environment, (3) their perception of nature conservation and (4) their perception of tourism. Then, taking all these aspects into account, (5) how local communities, in general, perceive their relationship with the p ark and its authorities. This study looked at the communities of Kurland, Nature’s Valley, Covie and Storms River. It shows in concurrence with other studies, that despite progressive laws and policies that express the intention of the South African state and SANParks to embrace the participatory approach, its implementation o n t he g round is riddled with challenges. , Thesis (MSocSc) -- Faculty of Humanities, Athropology, 2021

- Description: This study investigates whether a leadership and management development programme changed the management perceptions of the teachers of one of the schools that participated in the programme. The programme seeks to change the organisational culture of schools and develop effective management. The development philosophy of the programme is informed by literature on school effectiveness, organisation development, whole school development and systemic change. My research is conducted in the interpretive paradigm. Interpretive researchers view reality a construct of the human mind, and therefore the way people perceive the world is not necessarily the same since there can be different understandings of what is real. I employ convenience sampling to select the school and purposive sampling to identify my research participants. Whilst overall impression that the data conveys is that much of the programme does not seem to have had a lasting effect on the culture of the school, it nonetheless made an impression on the teachers’ perceptions of management. There clearly seems to be a greater appreciation of participative management processes. The reintroduction of proper prior planning played a decisive role in re-establishing sound work ethics at the school and contributes to a more structured approach to events at the school. Some sort of organisational learning has also been introduced at the school. The realisation on the part of the staff that they now have their destiny in their own hands is an especially critical development. And whilst the vision is not a compelling force in the organisation, it has nevertheless produced some strategic focus at the school. The insights and skills they acquired concerning resource management will also stand them in good stead.

- Description: Tax avoidance has been the subject of intense scrutiny lately by both the South African Revenue Service ("the SARS") and the media. This attention stems largely from the recent withdrawal of section 103(1) together with the introduction of section 80A to 80L of the South African Income Tax Act. However, this attention is not limited to South Africa. Revenue authorities worldwide have focused on the task of challenging tax avoidance. The approach of the SARS to tackling tax avoidance has been multi-faceted. In the Discussion Paper on Tax Avoidance and Section 103 (1) of the South African Income Tax Act they begin with a review of the distinction between tax evasion, tax avoidance and tax planning. Following a call for comment the SARS issued an Interim Response followed by the Revised Proposals which culminated in the withdrawal of the longstanding general anti-avoidance rules housed in section 103(1) and the introduction of new and more comprehensive anti-avoidance rules. In addition, the SARS has adopted an ongoing media campaign stressing the importance of paying tax in a country with a large development agenda like that of South Africa, the need for taxpayers to adopt a responsible attitude to the management of tax and the inclusion of responsible tax management as the greatest measure of a taxpayer's corporate and social investment. In tandem with this message the SARS have sought to vilify those taxpayers who engage in tax avoidance. The message is clear: tax avoidance carries reputational risks; those who engage in tax avoidance are unpatriotic or immoral and their actions simply result in an unfair shifting of the tax burden. The SARS is not alone in the above approach. Around the world tax authorities have been echoing the same message. The message appears to be working. Accounting firms speak of a "creeping conservatism" that has pervaded company boardrooms. What is not clear, however, is whether taxpayers, in becoming more conservative, are simply more fully aware of tax risks and are making informed decisions or whether they are simply responding to external events, such as the worldwide focus by revenue authorities and the media on tax avoidance. Whatever the reason, it is now critical, particularly in the case of corporate taxpayers, that their policies for tax and its attendant risks need to be as sophisticated, coherent and transparent as its policies in all other areas involving multiple stakeholders, such as suppliers, customers, staff and investors. How does a company begin to set its tax philosophy and strategic direction or to determine its appetite for risk? A starting point, it is submitted would be a review of the distinction between tax evasion, avoidance and planning with a heightened sensitivity to the unfamiliar ethical, moral and social risks. The goal of this thesis was to clearly define the distinction between tax evasion, tax avoidance and tax planning from a legal interpretive, ethical and historical perspective in order to develop a rudimentary framework for the responsible management of strategic tax decisions, in the light of the new South African general anti-avoidance legislation. The research methodology entails a qualitative research orientation consisting of a critical conceptual analysis of tax evasion and tax avoidance, with a view to establishing a basic framework to be used by taxpayers to make informed decisions on tax matters. The analysis of the distinction in this work culminated in a diagrammatic representation of the distinction between tax evasion, tax avoidance and tax planning emphasising the different types of tax avoidance from least aggressive to the most abusive and from the least objectionable to most objectionable. It is anticipated that a visual representation of the distinction, however flawed, would result in a far more pragmatic tool to taxpayers than a lengthy document. From a glance taxpayers can determine the following: That tax avoidance is legal; that different forms of tax avoidance exist, some forms being more aggressive than others; that aggressive forms of tax avoidance carry reputational risks; and that in certain circumstances aggressive tax avoidance schemes may border on tax evasion. This, it is envisaged, may prompt taxpayers to ask the right questions when faced with an external or in-house tax avoidance arrangement rather than simply blindly accepting or rejecting the arrangement.

- Description: The development of the High Rate Algal Pond (HRAP) as an independent tertiary treatment unit operation for phosphate and nitrate removal is reported. A novel Integrated Algal Ponding System (lAPS) design is proposed for nutrient removal from the effluents of both a conventional domestic sewage treatment plant and from an Advanced Integrated Wastewater Ponding System (AIWPS). The viability of an independently operated HRAP has been identified and termed the Independent High Rate Algal Pond (l-HRAP). A 500 m² pilot 1- HRAP was operated in such a way as to facilitate the precipitation of calcium phosphate, known to be controlled by pH (greater than 9.4) and resulting in final phosphate levels of less than 1 mg.L⁻¹ as P0₄-P. The incorporation of the I-HRAP into a denitrification process was also investigated. Continuously fed column reactors, utilising algal biomass as a carbon source, showed that the heterotrophic bacterial community dominant in the anaerobic algal sludge were denitrifying the nitrate in the feed. It was demonstrated that as the cultures were stressed (using increased nitrate concentrations, anaerobiosis and light starvation) total polysaccharide (TPS) concentrations increased, with a notable increase 111 the exopolysaccharide (EPS) fraction. These experiments corroborated the hypothesis that harvested microalgal biomass can be manipulated to produce, and release, exopolymeric substances under stress conditions, and which may serve as carbon source for denitrification. In both batch flask studies and in laboratory-scale reactor systems, harvested microalgal biomass from an HRAP was shown to produce exopolymeric substances under stress conditions. Initial high loading-rates of greater than 20 mg.L⁻¹ NO₃-N resulted in double the amount of exopolysaccharide production than in flasks with initial low loading-rates (less than 5 mg.L⁻¹ NO₃-N). Making use of an upflow anaerobic sludge blanket-type degrading-bed reactor, and an anaerobic, flooded trickle filter (ANTRIC) receiving HRAP effluent, the relationship between denitrification and the changes in polysaccharide content was investigated. This phenomenon has considerable beneficial implications in biological wastewater treatment systems where high nitrate concentration in the final effluent is a potential mitigating factor. Identification of the heterotrophic bacteria active in the denitrification process was attempted. This study presents a first report on the development and operation of the I-HRAP and has been followed by a technical-scale pilot plant evaluation of the process in the tertiary treatment of domestic wastewaters.

An ecological study of territoriality in four Cichlid species resident on rocky shores near Monkey Bay, Lake Malawi

- Description: This study centres on a diverse assemblage of epilithic algal grazing fish (17 cichlids and 2 cyprinids) found on the rocky shores near Monkey Bay, Lake Malawi. Diet overlap among these species is large, but competitive exclusion is apparently avoided by the species having different feeding structures, behaviour and distribution on the shore. In many respects the ecology and behaviour of the cichlid fishes inhabiting the rocky zones of Lake Malawi parallel those of coral reef fish. In both communities there are species which are highly territorial, resulting in resource subdivision and, in some cases, the development of algal gardens. As this behaviour has not been previously reported for cichlid species, this thesis describes the territoriality of the rock-dwelling cichlids of Monkey Bay, Lake Malawi, and poses three specific questions: 1. What is the function of territoriality? 2. How do the territorial species subdivide the space resource? 3. What prevents one species taking over all the available space? It is suggested that interspecific territoriality evolved in response to a shortage of food, and, at present, serves principally to defend an algal garden i.e. a food supply of high standing crop. The species studied are extremely site specific. The rocky shore is subdivided among the four species according to the rock configuration, size, algal mat composition and position on the shore, of the available sites. An experimental study of the space utilization of the two common territorial species, referred to as 'Pseudotropheus orange cheek' and 'Pseudotropheus aggressive', showed that suitable territory sites are in short supply and that these species are in competition for some sites. These results do not support those of Fryer (1959) who suggested that a superabundance of food enabled fish to coexist by sharing the same food resource. Indeed it now appears that a shortage of food may have been a major driving force during the recent evolution of the species studied.

- Description: The aim of this thesis is to examine what affect, if any, finding an argument both unanswerable yet unbelievable has on three purported first-person doxastic constraints. The three proposed constraints are the principle of truth, the principle of adequate reason and the principle of epistemic explanation. In Chapter 1, I lay out the claim of each of these constraints; differentiate them from one another, examine under what conditions they can be said to apply and provide what I take to be the strongest arguments for each of them. In Chapter 2, I explicate what I mean by finding an argument unanswerable yet unbelievable. In Chapters 3, 4 and 5, I detail how it is that finding an argument unanswerable yet unbelievable could constitute a threat to each of these constraints. I conclude that while the principle of adequate reason is undermined in the face of this threat, both the principle of truth and the principle of epistemic explanation fail to be undermined by this challenge.

- Description: The aim of this thesis is to examine what affect, if any, finding an argument both unanswerable yet unbelievable has on three purported first-person doxastic constraints. The three proposed constraints are the principle of truth, the principle of adequate reason and the principle of epistemic explanation. In Chapter 1, I lay out the claim of each of these constraints; differentiate them from one another, examine under what conditions they can be said to apply and provide what I take to be the strongest arguments for each of them. In Chapter 2, I explicate what I mean by finding an argument unanswerable yet unbelievable. In Chapters 3, 4 and 5, I detail how it is that finding an argument unanswerable yet unbelievable could constitute a threat to each of these constraints. I conclude that while the principle of adequate reason is undermined in the face of this threat, both the principle of truth and the principle of epistemic explanation fail to be undermined by this challenge.

- Description: The two point threshold was studied extensively by the psychophysical experimenters of the last century. More recent formulations in signal detection theory have suggested that the statements of these workers about absolute thresholds should be viewed with caution. This study investigates the two point threshold in the light of these formulations, and has two main aims :- (1) To state and deal with the problem of relating a limitation in perceptual ability, such as that which is represented by the two point threshold, to the receptor organisation of the body. (2) To demonstrate a practice effect on the two point threshold, and to consider this in the light of (1) above. To fulfil these two aims, a model of the neural mechanisms underlying the discrimination of two points applied to the skin is proposed, and this is able to accommodate what is known of the two point threshold. Although the model is simple it explicitly accounts for size transfer and the practice effect, and provides some clues as to the type of neural mechanism capable of producing them. The practice effect is demonstrated experimentally, and the results are then referred to the model proposed. The physiology of an organism sets the limits for its behaviour. 'The first aim is thus an important one, in that it considers a specific case of this general problem. And secondly, the practice effect on the two point threshold is typical of a number of fairly simple "learning" phenomena, which are part of the psychologists' study of learning.

- Description: Iron polychlorophthalocyanine (FePc(Cl)₁₆) and tetrasulfophthalocyanine ([M¹¹TSPc]⁴) complexes of iron, cobalt and manganese are employed as catalysts for the oxidation of cyclohexane using tert-butyl hydroperoxide (TBHP), chloroperoxybenzoic acid (CPBA) and hydrogen peroxide as oxidants. Catalysis using the FePc(Cl)₁₆ was performed in a dimethylformamide:dichloromethane (3 :7) solvent mixture. For the [Fe¹¹TSPc]⁴⁻, [Co¹¹TSPc]⁻ and [Mn¹¹TSPc]⁴⁻catalysts, a water:methanol (1:9) mixture was employed. The products of the catalysis are cyclohexanone, cyclohexanol and cyclohexanediol. The relative percentage yields, percentage selectivity and overall percentage conversion of the products depended on types of oxidant, or catalyst, concentrations of substrate or catalysts and temperature. TBHP was found to be the best oxidant since minimal destruction of the catalyst and higher selectivity in the products were observed when this oxidant was employed. Of the four catalysts investigated [Fe¹¹TSPc]⁴⁻ yielded the highest overall percentage conversion of 20%.The mechanism of the oxidation of cyclohexane in the presence of the FePc(Cl)₁₆ and [M¹¹TSPc]⁴⁻ involves the oxidation of these catalysts, forming an Fe(IlI) phthalocyanine species as an intermediate. Electrocatalysis using [Co¹¹TSPc]⁴⁻ as catalyst, employed an aqueous pH 7 buffer medium for electro-oxidation of 4-pentenoic acid. An enone is suggested as the only oxidation product of 4-pentenoic acid. No degradation of [Co¹¹TSPc]⁴⁻ was observed during the electrocatalytic process. In this process water was used as a source of oxygen therefore eliminating the production of by products from oxidant as in the case of TBHP and CPBA. This system was studied In an attempt to set up conditions for alkane electrocatalytic oxidation.

- Description: The human resource is constantly cited as an organisation's greatest asset. In a rapidly changing technological environment this is most applicable to the Information Technology (IT) function. Organisations are experiencing IT human resource problems such as low satisfaction, early plateauing, high turnover, burnout, limited advancement potential, nominal corporate commitment, supervisory aversion, poor organisational culture, and exceptional compensation. These problems are directly related to the IT professional's career. There is a lack of information and awareness surrounding IT careers to deal effectively with these problems. The research aims to create increased awareness of IT careers and the inherent problems through the development of a career management model. The research aims to identify the factors that influence IT careers, provide career management with a means to measure compatibility of the factors, and suggest solutions to incompatibility. The solving of this problem will be of mutual benefit to both organisations and individuals as they seek to better manage IT careers. After reviewing research literature relating to career anchors, IT job types, IT skills portfolios, and career dynamics a model for Effective IT Career Management (EITCM) has been constructed. The model represents the dynamic interactions between individual, organisational, and dependent factors. The model examines the compatibility of these interacting factors by measuring the levels of relevant career variables. The model suggests appropriate career management techniques to increase the compatibility of the interacting factors. An empirical study was designed and launched online to provide data that would confirm the seven Critical Success Factors (CSF) relating to the proposed model. The responses from the members of the Computer Society of South Africa (CSSA) allowed the seven hypotheses derived from the CSFs to be tested. The results of the empirical study were positive but required modification to five of the CSFs before they could be confirmed. The EITCM model was modified to reflect the improved CSFs. An awareness of career influencing factors combined with active career management is advantageous to both IT professionals and their organisations.

- Description: Many white primary schools in South Africa have acquired computers which are being used in various ways. In my experience few members of staff are confident enough to use the computers in the school for educational purposes. Those who have been using them, generally have been doing computer literacy. The teachers in our school expressed the view that they would like to be able to use the computer, but that they lack the necessary skills and therefore would welcome some form of training. In my opinion computers should form an integral part of a child's learning environment. It has, for some time formed a part of his social environment, either in the home or in the workplace. For computers to be used effectively in the classroom, it follows that the teachers need to be trained to use them. In an attempt to overcome this problem, I designed and presented an in-service course, which used selected computer assisted learning (CAL) programs with teachers. These teachers then used these programs with the pupils in their class and evaluated the pupils' reactions to the innovation. As a result of the observations and the feedback provided by the sample of teachers, it is suggested that this might be a possible approach to in-service training for other schools. With adaptation it should be possible to follow this approach in any school which has a computer and someone on the staff who is willing to take the initiative to implement such an innovation.

- Description: Driven by the needs of growing populations, industrial and governing powers are successfully accelerating the rate of industrial consumption, production and employment as if the earth’s resources are in unlimited supply. In contrast, a range of international sustainable development forums, inspired by visionary individuals, have made significant progress in creating awareness that the footprint of human activity is exceeding the earth’s sink and source capacity; and educating people in government, workplaces and communities to slow down industrial consumption and clean up production. Turning around conventional and short sighted ‘business as usual’ logic, and directing economies toward greener, long-term sustainability outcomes, still meet with resistance and hidden unsustainable agendas. The ‘green economy’ drive nevertheless since 2008 attracts financial and human resources and bold action in favour of more sustainable management of human-nature relations. The sustainable development movement for example advocates a ‘triple bottom line’ approach, holding that socially and ecologically responsible economic development would be sustainable. The sustainability movement has attained significant buy-in among governments and business communities. It forms the under-labouring philosophy of the programmes reviewed in this case study. The thesis reviews social-economic events paving the way for a global green economy. Taking a leadership role in the sustainable development movement the United Nations (UN) and the Organisation for Economic Co-Operation and Development (OECD) concurred to respond to the 2008 world-wide economic meltdown with a two-pronged ‘Green New Deal’ (UNEP, 2008). The Green New Deal financial package helps restore multi-national economic growth, employment and markets while re-shaping economies to follow an ecologically and socially responsible growth trajectory. South Africa implements green economy principles as part of the 2010 The New Growth Path overarching policy framework, with an implementation strategy embedded in the 2011 National Development Plan (NDP) (RSA. The Presidency, 2010; 2011). The New Growth Path emphasises that the transformation of South Africa’s un-sustainable economic and educational legacy to a more sustainable future is not expected to follow a smooth, linear process. The transition to a green economy is rather expected to be an event of “… noisy, healthy democracy” (RSA. The Presidency, 2010). A green, low carbon economy particularly constitutes a pledge to slow down and turn the human induced climate change trajectory around. McKinsey (2009) argues that this pledge is attainable on a world-wide scale, as sufficient and suitable environmentally sound techniques and technologies are already in place. Attaining buy-in from business stakeholders toward re-thinking and amending an economy’s self-defying large environmental footprint (inclusive of carbon, water and waste footprints) however requires education starting with awarenessraising followed by educational programmes and official curricula aimed at implementation and continuous improvement of green practices in day to day ‘doings and beings’ (Sen, 1997). This study at implementation level reviews two green economy training programmes and their emergence in South Africa around this rationale. The awareness generation and training programmes elected as case study examples are the ‘Resource Efficient and Cleaner Production’ (RECP) and ‘Industrial Energy Efficiency’ (IEE) programmes, of the hosting agency National Cleaner Production Centre of South Africa (NCPC-SA). The RECP and IEE teams reach out to decision makers, engineers and artisans at industrial workplaces and workplace related events to add green competences to their business-as-usual skill sets. Implementing green options in industry typically slows down industrial scale resource consumption, pollution, waste generation and green-house gas (GHG) emissions while optimising resource productivity and enterprise excellence. Optimised supply side systems allow industry to reduce energy and material intensity of products thus reducing cost and producing more with less. In transitioning to a ‘Green GDP’ economy South Africa is awakening to the reality that natural resources constitute the original, albeit limited feedstock for growth and employment. The RECP and IEE approach also contribute to reduction of industrial waste, waste-to-landfill, and energy and resource security. Literature reviewed for this research provides evidence that the green economy’s triple bottom line philosophy is quantifiable thus manageable. A range of green economy management tools are emerging, including guidelines for carbon, water and environmental footprinting and the green-house gas abatement cost curve (see section 2.2.5) (McKinsey and Company, 2009). Transitioning from business as usual to ecologically sustainable industrial sectors however requires visionary, educated leadership, willing and capable of introducing modern and more efficient techniques and technologies. The boundaries of this half thesis embrace the globally and historically significant Tbilisi Declaration and other education and sustainable development agreements produced by United Nations and OECD mechanisms. Participating nations like South Africa incorporate the essence of these agreements into domestic policies and strategies, and align industries to remain competitive in international markets, which are increasingly enforcing green standards like ISO 14001 and ISO 50001. The focus of this case study guided by inductive, abductive and retroductive inference is to understand how the two sustainability learning programmes for people in industrial workplaces, supported by the United Nations Industrial Development Organisation (UNIDO) and relevant donors, and overseen by the South African Department of Trade and Industry (the dti), relate to emerging green learning aspects. Producing a review of this nature requires a framework of laterally understanding emerging green learning aspects, for which I have reviewed green economy literature and also green learning and conventional education and training literature respectively. Themes emerging from the literature review informed an analytical instrument (questionnaire) in Phase One. In Phase Two the questionnaire was applied through nested case study methodology to show how the educational content and approaches of the RECP and IEE programmes relate to emerging green learning aspects and as such is suitable for mainstreaming in the national educational system. From an explicit educational perspective potential partners for collaboration include the Department of Higher Education and Training (DHET) the South African Qualifications Authority’s (SAQA’s) Quality Council for Trades and Occupations (QCTO) and the Sector Education and Training Authorities (SETAs) representing the training needs of the industrial workforce but affiliated to QCTO and SAQA. In the extended scenario the NCPC-SA as a dti programme recognises the Department of Environmental Affairs (DEA) as lead agency guiding implementation of South Africa’s green economy, and specifically DEA’s National Environmental Sector Skills Planning Forum (NESPF), a national leader in green skills development in South Africa, as conduit for productively mainstreaming relevant RECP and IEE content and approaches toward green skills development for the green economy.

- Description: From introduction: This is a study of the physical landscape, climate, natural vegetation, historical geography and rural land use of the Bedford, Adelaide, Fort Beaufort, Stockenström and Victoria East magisterial districts. These five districts may be regarded as a natural region bounded by the crest of the Amatole-Winterberg range in the north and by the Great Fish River in the west. The southern boundary is a zone of semi-arid scrub bordering the Great Fish River valley. The Ciskei may be regarded as the eastern boundary of the region.

- Description: Berkheya Ehrh. is a genus of daisies in the tribe Arctotideae, subtribe Gorteriinae with over 80 species, most of which occur in southern Africa. This genus has centres of diversity associated with the montane regions of South Africa, including the Drakensberg Alpine Centre and Mpumalanga escarpment regions. Previous molecular and morphological studies indicate that Berkheya is paraphyletic. I present phylogenies based on nrDNA (ITS; Internal Transcribed Spacer) and cpDNA (psbA-trnH) sequence data analysed with Bayesian Inference and Parsimony. A phylogeny of combined cp- and nrDNA is also presented. These phylogenies are used to assess generic limits and to investigate the biogeographic patterns of Berkheya and its allies. The ITS phylogeny shows five well supported clades of Berkheya, two of which (Clades I and 2) are monophyletic summer rainfall region clades. Clades 3 to 5 are all paraphyletic winter rainfall clades with Cullumia occurring in the third clade, Cuspida occurring in the fourth and Didelta in Clade 5. Both psbA-trnH and combined phylogenies show concordance with the clade distribution shown in the ITS phylogeny. The ITS phylogeny was used to analyse correspondence with Roessler’s (1959) Series. It was found that the phylogeny showed considerable agreement with Roessler’s series, but B. bipinnatifida and B. spinosa of Series Speciosae may require some revision as well as taxa of monotypic series Cruciatae and Angustae. It is suggested that the latter series be merged with Cullumia species to form a single series. Some consideration should be taken to include Didelta species into Series Fruticosae as Didelta occurs in subclade 5b of Clade 5 with other Series Fruticosae taxa. Achene morphology was examined from species from each of the five clades to investigate the relationships of Berkheya and its allies, as well as to determine if there were any consistent achene features for each clade. The structure of surface cells on the fruit, the presence, absence and morphology of twin hairs as well as the structure of the pappus scales were found to be most useful in reflecting phylogenetic relationships within the clades. When compared with the clades of the ITS phylogeny, achene morphology showed consistent characters between taxa occurring in the same clades. As the most comprehensive study involving Berkheya, this phylogenenetic investigation was able to confirm that Berkheya is a paraphyletic genus with Didelta, Cullumia and Cuspida needing to be subsumed into Berkheya. An alternative classification is that taxa of Clade 5 could possibly be erected as an expanded Didelta, separate and sister to Berkheya.

- Description: This thesis takes the form of an in-depth case study within which the play therapy process of an aggressive 5-year-old boy was explored. The aim of the research was to examine the abundant expressions of aggression that were present within his therapy, and in so doing reflect their rich communicative content and their relevance and purpose in the development of his Self. Object relations theory formed the lens and theoretical context for this research with Winnicott’s contributions and Parens' model of aggression being considered in particular. A detailed data resource of the therapy process was compiled and transposed into narrative form. These narratives were reviewed with a reading guide as a means to facilitate a hermeneutic exploration of the data. The emergent themes were considered against the case data and the current theory, which allowed for their further analysis and development. From this the value of using Parens’ model was considered and deemed useful although limited in its contribution. The analysis and the themes which emerged conveyed how within this case the child’s aggression presented as: a significant feature of his ambivalence towards relationships; a powerful and pervasive protective fantasy of omnipotence; inherently linked to his sense of self and self expression; and as actively involved in his True Self’s hope-filled attempts for an alternative experience. This thesis provides a descriptive account of a challenging case, offering insights into the value and meaningful content of aggressive behaviours, with the intention being to reflect that which is often not easily appreciated or readily observable within such a therapy process, a trace of hope.

A theological consideration of the office, sacrifice, ministry and perfection of Christ as high priest in the Epistle to the Hebrews, and their significance for the believer and the community of faith

- Description: In these last days God has spoken his last and most complete word to man in a Son, Jesus Christ. In his person and ministry Christ is the agent of creation and heir of the spiritual and material estate of God. He is the locus of the fulfilment of the revelatory plan of God, and, as such, is superior to the angels, the ministers of salvation within the created order, and Moses, the faithful minister of God's people Israel. Christ not only fulfils the necessary qualification for priesthood under the old covenant, that of divine appointment, but is appointed by God a high priest for ever after the order of Melchizedek. This establishes and authenticates the high priestly office of Christ. Jesus Christ, Iike the high priests of the old covenant, must offer gifts and sacrifices to God. The sacrifice of Christ fulfils the sacrificial code of Leviticus 1-7, his sacrifice being a gift to God, communion with God, and an expiatory sacrifice. But more than this the sacrifice of Christ fulfils the Day of Atonement ritual of Leviticus 16 as well as the covenant sacrifice of Exodus 24. The sacrifice of Christ is essentially once for all, being that unique action which alone can ultimately deal with sin. The uniqueness of Christ's sacrifice depends on the uniqueness of the person of Christ and his superior high priestly office. In his sacrificial action Christ is also the sin-bearer. The high priestly sacrifice of Christ determines the form of the high priestly ministry of Christ, which is also gift to God, communion with God, has expiatory significance, and is a ministry of the new covenant . The high priestly ministry of Christ is a ministry which is continuous through time and is both contemporaneous with and subsequent to his sacrifice. In this continuity through time the ministry of Christ is the foundation of both the faith of believers and their perfection as sons. In the execution of his high priestly ministry Christ is perfected by God through the learning of obedience. The humiliation of Christ and his learning of obedience becomes the foundation of the perfecting of believers. It is as the One who is perfected through suffering that Christ becomes the pioneer of salvation and the pioneer and perfecter of the faith of the people of God. Through faith in Christ the people of God constitute a pilgrim people who, on the basis of Christ's perfection, are themselves perfected and brought to glory. The pilgrim people of God share in the priesthood of Christ and constitute a priesthood of all believers. In their pilgrimage of faith they are to demonstrate their confidence, endurance, obedience, and discipline, and in their running of the race of pilgrimage are to exercise their own ministry as they progress to glory and the sabbath rest of God. The high priesthood of Christ has implications for the common life of the people of God and is at the foundation of our understanding of the Christian life.

- Description: Since 2001, South African teachers have been attempting to practise inclusive education in classrooms in ordinary, public schools. Previous research has shown the many challenges South African teachers face in our current educational environment. Strong arguments, however, have been made for more research to be done on actual teacher engagement with learners in our ordinary, public school classrooms, and the extent to which classroom practices are inclusive (Engelbrecht, Nel, Nel & Tlale, 2015, p. 3). This study sought to do an in-depth critical analysis of three foundation phase teachers and their engagement with learners in their classrooms at an Eastern Cape school. The aim was to examine how inclusive education was being enacted by the teacher with learners in real classroom settings, with particular attention paid to ways in which learners experience barriers to learning. A micro-level analysis was conducted in a single unit case study and using a qualitative research approach in an interpretive paradigm. Questionnaires, observations, and semi-structured interviews were conducted in an attempt to gather in-depth data. It was heartening to observe the extent to which inclusive education and practices were being enacted at the school and in the classrooms, and instructive in providing examples of what can work in the South African context. Key findings of this study include the generation of a framework for analysing inclusive classroom practice at the micro level. Criteria were identified as indicators of inclusive education of learners including those experiencing barriers to learning in the classroom. This study builds on and extends what has been developed at the macro and micro level of inclusive education in schools and in the classroom. It found that a number of challenges remain for enabling the implementation of an inclusive education. At the macro level, these include the provision of clear directives for implementation of inclusive education by the appropriate authorities; the provision of well-structured professional teacher training and development programmes in inclusive classroom practices, as well as in barriers to learning and how to address them; and the provision of funding for school and classroom infrastructure and resources. At the micro level, these include the successful implementation by teachers of inclusive classroom practices and the provision of the necessary support for learners experiencing barriers to learning in their classrooms, including expert personnel, resources, and assistive devices.
