- Description: This thesis analyses the doctrines of the sham and the alter-ego and their application to the law of trusts in South Africa. Following an initial examination of the historical development of the law of trusts in English law and the principles of equity law, the study focuses on the current legal status of the trust inter vivos in South Africa and the similarities to its English forerunner. The work traces the sham doctrine back to its origins in English law, where the term “sham” was first used in the context of fraud and dishonesty in cases involving matters arising from hire-purchase agreements, and explains how it gradually began to find its place in the law of trusts. During the exploration, the work highlights the cornerstone of the sham doctrine’s development, the Snook test, which in effect became the internationally accepted guideline for any sham trust enquiry. In terms of the alter-ego doctrine, the work highlights the birth of the principle in Australian law and the doctrine’s immediate reception into other common law jurisdictions and its resultant development. The growth, maturity and popularity of the doctrines are key to the thesis and, in the course of the investigation, the study provides a legal-comparative analysis of the treatment of the doctrines in the context of trusts against that in other common law countries. The study then shifts its focus to South Africa’s interpretation and application of these doctrines in trust law, and reveals the erroneous judicial development in which the courts have in some instances mistakenly replaced the sham doctrine with the company law doctrine of piercing the corporate veil or, in other instances, have erroneously conflated the two trust doctrines. The results highlight a breach of a fundamental rule observed overseas – the “no half way house” rule, which specifically cautions against South Africa’s chosen direction when allowing the lifting of a trust’s veil. The study closes with suggestions as to how the country could reconcile the problems underlined in the thesis by means of law reform, as well as offering practical advice for settlors, trustees and beneficiaries, the core of which is given in the handbook that accompanies this thesis.

- Description: Novel oxovanadium(IV) complexes of glycine, ʟ-alanine, 1-methylimidazole-2-carboxylic acid, imidazole-2-caboxylic acid and imidazole-4-carboxylic acid were synthesized and isolated in the solid state. The ligands and complexes were characterized by elemental analysis, melting point, NMR, IR and UV-vis spectroscopy. The IR studies showed that glycine and ʟ-alanine coordinate monodentately through the amine nitrogen whilst the imidazole-carboxylic acid derivatives assume a bidentate chelation. The electronic spectroscopic studies indicate distorted octahedral geometry for the oxovanadium complexes of amino acids and a square pyramidal geometry for oxovanadium(IV) complexes of imidazole carboxylic acid derivatives. The reaction of vanadyl (VO2+) with glycine, ʟ-alanine, imidazole-2-cabrboxylic acid, imidazole-4-carboxylic acid and 1-methylimidazole-2-carboxylic acid was studied in aqueous solution by pH-potentiometry under oxygen and carbon dioxide-free conditions. The data obtained from these titrations were used to calculate the protonation and stability constants. The results showed that all ligands are suitable for bidentate coordination in the formation of monomeric species although the solid state studies of the oxovanadium(IV) complexes of amino acids showed a monodentate coordination. The overall stability constants for the (VIVO)-ʟ-alanine system (log β120 = 18.27(6)), (VIVO)-glycine system (β120 = 17.22(6)), (VIVO)-imidazole-4-carboxyic acid (β120 = 11.38(8)), (VIVO)-imidazole-2-carboxylic acid (β120 = 11.62(6)) and (VIVO)-1-methylimidazole-2-carboxylic acid (β120 = 15.49(9)) were obtained. The calculations for the species distribution in the experimental pH range showed that the neutral bis-coordinated complexes are dominant over the biological pH range. The glucose uptake effect of oxovanadium(IV) complex of ʟ-alanine, imidazole-4-carboxylic acid, imidazole-2-carboxylic acid and 1-methylimidazole-2-carboxylic acid was investigated using 3T3-L1 adipocytes, Chang liver and C2C12 muscle cells at various concentrations. The compounds had significant glucose uptake on Chang liver cells only at a concentration of 0.1-10 μM whilst in the C2C12 muscle and 3T3-L1 cells the compounds showed little to no activity probably due to the lower concentrations employed as a result of the cytotoxicity of these compounds on these two cell lines.

- Description: FundaWethu is reading software that is designed to deliver reading lessons to Grade R-3 (foundation phase) children who are learning to read in a multilingual context. Starting from a premise that the system should be both educative and entertaining, the system allows literacy researchers or teachers to construct rich multimedia reading lessons, with text, pictures (possibly animated), and audio files. Using the design-based research methodology which is problem driven and iterative, we followed a user-centred design process in creating FundaWethu. To promote sustainability of the software, we chose to bring teachers on board as “co-designers” using the lesson authoring tool. We made the authoring tool simple enough for use by non computer specialists, but expressive enough to enable a wide range of beginners reading exercises to be constructed in a number of different languages (indigenous South African languages in particular). This project therefore centred on the use of designbased research to build FundaWethu, the design and construction of FundaWethu and the usability study carried out to determine the adequacy of FundaWethu.

- Description: Since the 1970s, the international economic system has become prone to the volatility and undue effects associated with booms and busts. This forty year period spanning the present has exhibited restrained growth and repressive economic development. Critical changes to the system are presented by the transition from "Fordism" to the post 1970s neoliberal regime and the globalization of world markets. Underpinning this transformation is an ideological shift towards free market capitalism and the adoption of "reduced form" market models. These "reduced form" models appear to hinder economic sustainability as their grounding in economics fails to account for real economic activity. This thesis aims to provide a more holistic perception of sustainability, one that provides a sound basis on which to develop sustainable economic policy. The Regulationist Approach presents the requisite understanding of economic sustainability required within this research. The inclusion of economic, historical and socio-political fields of research proposes a wider understanding of the political economy and sustainability. The application of the Regulation Approach to the South African economy illustrates many problem areas that require attention. The examination found that firstly, aggregate demand in the South African economy was unsustainable due to the debt driven nature of demand under the asset price bubble of the mid to late 2000s. Secondly, aggregate supply also proved unsustainable as government is failing to provide any substantive growth within important sectors of the economy such as education and the provision of general services. Furthermore, the adoption of inflation targeting in South Africa poses a barrier to sustained economic growth as it focuses singularly on price inflation. The "reduced form" model of inflation targeting fails to account for market failures and a number of vital indicators of sustainability most notably, debt levels and asset prices. The inclusion of these indicators, and financial stability more generally, are found to provide a more holistic and sustainable approach to macroeconomic policymaking.

- Description: South Africa enjoys strong policy support for the integration of environmental issues into school curricula. However, much doubt exists over the extent to which this has been converted into appropriate classroom practice at the majority of under-resourced rural schools in the country. This article reports on a study which piloted a research tool which can be used to analyse teachers’ lessons, with the aim of gaining insight into the extent to which they integrate natural resource management issues. The research tool was based on Bernstein’s concept of classification and consisted of five indicators of natural resource management integration into Life Sciences lessons. The study contributes to the design of research tools that can be used to analyse and monitor the integration of environmental issues into teachers’ lessons. It also provides some insight into the environmental content of a sample of Grade 10 Life Sciences lessons at four rural underresourced schools in the Eastern Cape.

- Description: The southern African marine realm is located at the transition zone between the Atlantic and Indo-Pacific biomes. Its biodiversity is particularly rich and comprises faunal and floral elements from the two major oceanic regions, as well as a large number of endemics. Within this realm, strikingly different biota occur in close geographic proximity to each other, and many of the species with distributions spanning two or more of the region's marine biogeographic provinces are divided into evolutionary units that can often only be distinguished on the basis of genetic data. In this review, we describe the state of marine phylogeography in southern Africa, that is, the study of evolutionary relationships at the species level, or amongst closely related species, in relation to the region's marine environment. We focus particularly on coastal phylogeography, where much progress has recently been made in identifying phylogeographic breaks and explaining how they originated and are maintained. We also highlight numerous shortcomings that should be addressed in the near future. These include: the limited data available for commercially important organisms, particularly offshore species; the paucity of oceanographic data for nearshore areas; a dearth of studies based on multilocus data; and the fact that studying the role of diversifying selection in speciation has been limited to physiological approaches to the exclusion of genetics. It is becoming apparent that the southern African marine realm is one of the world's most interesting environments in which to study the evolutionary processes that shape not only regional, but also global patterns of marine biodiversity.

(Salviniaceae), water lettuce, Pistia stratiotes L. (Araceae), parrot's feather, Myriophyllum aquaticum (Vell.) Verdc. (Haloragaceae), and red water fern, Azolla filiculoides Lam. (Azollaceae) has been ongoing in South Africa since the release of the first biological control agent on water hyacinth in 1974. This review provides an account of progress for the period from 1999. Post-release evaluations over the last three years have shown that, with the exception of water hyacinth, all of these problematic aquatic plants have been suppressed effectively using classical biological control. In eutrophic water bodies at high elevations that experience cold winters, an integrated approach, that includes herbicide application and augmentive biological control, is required against water hyacinth. The grasshopper Cornops aquaticum (Brüner) (Orthoptera: Acrididae: Leptysminae) has recently been released as a new agent for water hyacinth, and Megamelus scutellaris Berg (Hemiptera: Delphacidae) and Taosa longula Remes Lenicov (Hemiptera: Dictyopharidae) are being considered for release on water hyacinth. The longterm management of alien aquatic plants in South Africa relies on the prevention of new introductions of aquatic plant species that could replace those that have been controlled, and, more importantly, on a reduction in nutrient levels in South Africa's aquatic ecosystems.

- Description: Pyura stolonifera is a large solitary ascidian found in Africa, Australasia and South America. The taxonomic status of different populations of this species is disputed, especially since there is evidence for several distinct morphological and genetic units that point towards the existence of multiple cryptic species. While some researchers still recognize P. stolonifera as a single species, others treat the different populations as distinct species. Here, we present a revision of the P. stolonifera species complex based on the examination of samples from all regions where there are reliable reports of this taxon. We recognize four species that are both morphologically and genetically distinct, one of which is new to science and is formally described here. This species is morphologically distinct from the other three members of the species complex in terms of the colour and texture of the tunic, the arrangement of the gonads within the gut and the shape of the dorsal tubercle, among other characters. We name the new species Pyura dalbyi after Dr. J.E. Dalby Jr., whose research on its ecology and distribution provided the incentive for examining this species more closely.

- Description: This journal reflects a diversity of environment and sustainability education research and viewpoints alongside two synthesis papers. Read as a whole and within a widely held ideal that diversity reflects resilience, the environment and education for sustainable development landscape in Africa might be said to be healthy and proliferating. But read against the pressure to produce tangible evidence of change on an African landscape of persistent climate variation and poverty, along with a widening gap between rich and poor, the picture remains challenging. These contrasting readings are notable at a time when we are looking towards the Association for the Development of Education in Africa (ADEA) Triennial in February, 2012, the Rio+20 Earth Summit in June 2012 and our own EEASA +30 conference in September 2012. The UN Decade of Education for Sustainable Development is characterised by a proliferation of education imperatives. These emerged as modern education in response to the issues of the day and now a modernity in deepening crisis.

- Description: This journal reflects a diversity of environment and sustainability education research and viewpoints alongside two synthesis papers. Read as a whole and within a widely held ideal that diversity reflects resilience, the environment and education for sustainable development landscape in Africa might be said to be healthy and proliferating. But read against the pressure to produce tangible evidence of change on an African landscape of persistent climate variation and poverty, along with a widening gap between rich and poor, the picture remains challenging. These contrasting readings are notable at a time when we are looking towards the Association for the Development of Education in Africa (ADEA) Triennial in February, 2012, the Rio+20 Earth Summit in June 2012 and our own EEASA +30 conference in September 2012. The UN Decade of Education for Sustainable Development is characterised by a proliferation of education imperatives. These emerged as modern education in response to the issues of the day and now a modernity in deepening crisis.

- Description: In 2009, South African police statistics revealed that more than 68 332 women were raped in the country. The evidence from independent researchers has shown that SAPS statistics are highly susceptible to under-reporting and the actual figure is more than double this amount. One pervasive feature of the phenomenology of rape is post-traumatic stress disorder (PTSD). PTSD is a highly debilitating condition with severe individual and societal costs. The condition takes a critical toll on occupational functioning, schooling and personal relationships and is associated with depression, suicide risk, self-harming behaviours and alcohol-abuse problems. The Ehlers and Clark (2000) cognitive model represents the most efficacious treatment for PTSD but the approach is severely under-utilised by South African practitioners working with sexual trauma. The reasons for such under-utilisation relate to a lack of exposure and training surrounding the model and concerns about the transportability of the treatment to a multi-cultural context. One method of addressing these barriers to treatment delivery is through systematic case-based research. Systematic case-based research offers a complementary means of refining theory and developing evidence-based practice in the context of a developing country. The method offers an intensive analysis and description of the particular phenomena under study within its real-life context. It allows the researcher to intensively examine and identify the specific aspects of the therapist’s responses and client’s reactions that contributed to significant change. Unlike efficacy studies, generalisability in case-study research is based on replication on a case-by-case basis and the creation of case law. This research study uses a systematic-case study approach to investigate the applicability of the Ehlers and Clark (2000) model in the treatment of rape-related PTSD in South Africa. The study aims to demonstrate the transportability of the model and develop a needed evidence base for service providers in the country. Seven women participated in the project and lent their treatment process to the research. The participants varied in terms of age, race, culture, socio-economic status and the nature of their sexual trauma. Through synoptic thematic analysis of their therapy process specific client-related personal aspects, client-related contextual factors and state-level factors were found to impede treatment delivery and implementation. The implications of these aspects for clinical practice and social policy are comprehensively discussed.

- Description: Global increases in urbanization and anthropogenic activity within wa-tersheds and catchment areas have resulted in excessive nitrogen loads in aquatic ecosystems. South Africa is deeply dependent on nat-ural resources for its economic health and as a consequence is particu-larly vulnerable to the degradation of its natural capital. Increased nitro-gen loading can result in widespread aquatic ecosystem degradation including: harmful algal blooms, increased turbidity, hypoxia, loss of aquatic vegetation and habitat and fish kills, it is also one of the mecha-nisms driving aquatic weed invasions. Understanding the fate and pro-cessing of anthropogenic nutrients in natural systems is therefore criti-cal for both preserving the well-being and biotic heritage for future gen-erations as well as providing a tremendous opportunity to improve the management driven by science. The objectives of this study were to evaluate the feasibility of mapping anthropogenic pollution through sta-ble isotopes signatures of aquatic plants, to investigate the potential for identifying different pollution sources, concentrations and distributions in a freshwater environment and to determine the utility of these tech-niques in indentifying early eutrophication.

In exploring some of the connections between musical identity and national identity, it sets out to discover what value WEAM holds for a certain group of student pianists. Qualitative empirical data was collected in the form of in-depth, semi-structured interviews and questionnaire responses, and the findings point to numerous, nuanced expressions of self and varied intersections of the nation with musical identity in the life of the individual. Further, WEAM appears to represent a crucial point of identification for these individuals, in each case generating positive affirmations of the self.

- Description: The aim of this thesis is to study a class of left-invariant optimal control problems on the matrix Lie group SE(2). We classify, under detached feedback equivalence, all controllable (left-invariant) control affine systems on SE(2). This result produces six types of control affine systems on SE(2). Hence, we study six associated left-invariant optimal control problems on SE(2). A left-invariant optimal control problem consists of minimizing a cost functional over the trajectory-control pairs of a left-invariant control system subject to appropriate boundary conditions. Each control problem is lifted from SE(2) to T*SE(2) ≅ SE(2) x se (2)*and then reduced to a problem on se (2)*. The maximum principle is used to obtain the optimal control and Hamiltonian corresponding to the normal extremals. Then we derive the (reduced) extremal equations on se (2)*. These equations are explicitly integrated by trigonometric and Jacobi elliptic functions. Finally, we fully classify, under Lyapunov stability, the equilibrium states of the normal extremal equations for each of the six types under consideration.

- Description: This article explores intersections between understandings of masculinity and nationalism. Etymologically, ‘patriotism’ refers to a love for a fatherland and a patriarchal order; it includes notions of loyalty, honour and a range of qualities often associated with conceptions of masculinity. But if gender remains fixed to these normative constructions, what happens to one’s sense of masculine identity when the national state changes? My interest lies in exploring how white South African men have been repositioned in terms of a shift in their gendered identification, with a reflection on the possibly tragic consequences of maintaining an overly rigid gender role identification. As long as masculinity is embedded within nationalism, it will be caught up within a defensive reactive mode which can turn self-destructive. In order to explore these ideas the article employs as its central metaphor the character of Dawid Olivier, who is the protagonist of Athol Fugard’s Sorrows and Rejoicings (2002).

In her Cape Town apartment she has nightmares about other houses. Her visits to her family home, where her elderly father lives alone, are similarly burdened by presences and memories she finds unwelcoming. And, her extended vacation to the UK, once she has discovered her family's secret, is a choice of “a place in which to cry” (Wicomb 2006: 191).

- Description: Arid and semi-arid environments are characterized by extreme fluctuations in temperature and low rainfall, which present significant challenges to the animals inhabiting these areas. However, the presence of burrows may allow animals to avoid climatic extremes and predators and may act as valuable foraging sites. We assessed the microhabitat conditions (maximum and minimum temperature, relative humidity and seed abundance) of aardvark (Orycteropus afer) burrows in relation to paired non-burrow areas at three sites in South Africa. We also describe the extent to which they are used as resources by other vertebrates. Maximum temperatures were significantly lower and minimum temperatures and relative humidity values were significantly higher inside the burrows than outside. The concentration of seeds inside the burrows and at the paired non-burrow sites was similar. Twenty-seven vertebrate species (21 mammals, two birds, three reptiles and one amphibian) were recorded making use of the burrows and it is likely that these species accrue benefits (e.g. a buffered microclimate) from burrow use. However, our sampling was biased towards mammals and nocturnal species. Consequently, we recommend further work to establish the overall reliance of vertebrate taxa on aardvark burrows in arid and semi-arid environments.

- Description: This research examines men’s talk around abortion using critical discourse analysis. Current literature indicates a dearth of studies addressing the topic of men and abortion in various domains. An understanding of men’s relationship to abortion, however, is crucial to understanding abortion as a social phenomenon. This study utilises the work of Foucault around discourse and power, as well as Butler’s work on gender to create a theoretical framework to approach data. Data were collected in the form of interview groups made up of men, as well as newspaper articles and on-line forum discussions that featured men as the author. What emerged from theses texts was a ‘Familial Discourse’ which posits the nuclear, heterosexual family as a long term relationship between a mother and father, which forms the ideal site to raise children. Discourses that support the family are a discourse of ‘Equal Partnership’ which establishes the man and the woman as being in a heterosexual relationship where each partner is seen to have equal power, and a discourse of ‘Foetal Personhood’ which constructs the foetus as a child in need of a family. Related to the heterosexual matrix, the formation of a family unit comes to be constructed as ‘natural’. Abortion acts as a disruptor to these discourses. By disrupting the formation of the family unit, abortion negatively affects the individuals involved. A relationship where a formation of a family unit was disrupted cannot survive. If the female partner has an abortion without her partner, it is seen as disrupting the equal partnership between the man and the woman. Men in this case see themselves as ‘powerless’ compared to women. From this point a ‘New Man’ discourse emerges, where men position themselves as loving and responsible in the context of a nuclear, heterosexual family unit. Abortion disrupts ‘Foetal Personhood’ and is constructed as murder. In the case of rape the ‘Familial Discourse’ can be invoked either to justify abortion or resist abortion, based on whether or not a family unit can be formed. These discourses reproduce patriarchy.

- Description: Enumeration of carbon stocks at benchmark sites is a necessary activity in assessing the potential carbon sequestration and possible generation of credits through restoration of intensively impacted sites. However, there is a lack of empirical studies throughout much of the savannas of sub-Saharan Africa, including South Africa. We report an estimation of species specific and site biomass and carbon stocks, and general vegetation structural attributes from three protected areas along a rainfall gradient in the central lowveld, South Africa. Estimates of biomass and carbon stocks were effected through destructive sampling to establish locally derived allometric equations. There was a gradient of increasing woody density, height of the canopy, number of species, density of regenerative stems and a greater proportion of stems in small size classes from the arid locality to the mesic locality, with the semi-arid locality being intermediate. The proportion of spinescent species decreased with increasing rainfall. The mesic locality was significantly more woody than either the arid or semi-arid sites, having double the biomass, four times the density and 40% higher basal area. Above ground carbon pools were also higher; carbon stocks were approximately 9 t/ha for the arid and semi-arid sites and 18 t/ha for the mesic site.

- Description: There has been a growing need in environmental education to develop students' ability and will to take part in democratic processes that enable them take environmental action in their local environment. This study examined learner action competence in waste management practices in two primary school contexts in the Eastern Cape, South Africa. An interpretive case study design is used to probe how learner participation in Eco-School waste management practices enabled the acquisition of knowledge in purposeful learning and action experiences that developed the vision and agency of informed action. The research was centred on two guiding questions: 1. How informed, purposeful and action-orientated is learner participation in Eco-School waste management activities? 2. What Eco-School waste management activities are fostering active participation towards a learner-led agency? Educators in the two schools were interviewed and Eco-School portfolios were examined for evidence of the learning activities and learner achievement. This provided the contextual data for reviewing focus group interviews to probe what was significant to learners, what they came to know and how they had contributed to the process of developing better waste management in the Eco-School context. The evidence generated in the study was used to identify the roles of the various players, the significant activities and processes that enabled and constrained the emergence of learner-led agency. The main findings in the study were that teacher intentionality and school management ethos were significant in engaging learners in meaningful waste management activities in both cases. The study also revealed that although most of the waste management activities in both cases were teacher-initiated, there were spaces open for learner initiatives. However, it appeared that the activity based waste management practices mostly allowed learners to learn how to do waste management more than allowing them to find out more about the scope and nature of ii the problem of waste. This then resulted in learners talking more about what they were doing with waste than talking about what they knew about waste. There were differences in the way in which learners approached waste in the two cases. In the one case, Kingswood Junior School learners used waste artistically and carried out activities that allowed for better use of waste resources like paper while in the other School, Grahamstown SDA School, learners approached waste as a resource for making money. However, in both cases, learners appeared to enjoy the positive experiences of doing things that contributed to a cleaner environment and were of benefit to others and this gave them a sense of pride to share their experiences with others. This study was significant as it allowed me to probe learner participation and examine the development of their action competence through listening to the voices of the learners themselves and understanding what was important to them about the knowledge they gained and their vision of better waste management.

- Description: There has been a growing need in environmental education to develop students' ability and will to take part in democratic processes that enable them take environmental action in their local environment. This study examined learner action competence in waste management practices in two primary school contexts in the Eastern Cape, South Africa. An interpretive case study design is used to probe how learner participation in Eco-School waste management practices enabled the acquisition of knowledge in purposeful learning and action experiences that developed the vision and agency of informed action. The research was centred on two guiding questions: 1. How informed, purposeful and action-orientated is learner participation in Eco-School waste management activities? 2. What Eco-School waste management activities are fostering active participation towards a learner-led agency? Educators in the two schools were interviewed and Eco-School portfolios were examined for evidence of the learning activities and learner achievement. This provided the contextual data for reviewing focus group interviews to probe what was significant to learners, what they came to know and how they had contributed to the process of developing better waste management in the Eco-School context. The evidence generated in the study was used to identify the roles of the various players, the significant activities and processes that enabled and constrained the emergence of learner-led agency. The main findings in the study were that teacher intentionality and school management ethos were significant in engaging learners in meaningful waste management activities in both cases. The study also revealed that although most of the waste management activities in both cases were teacher-initiated, there were spaces open for learner initiatives. However, it appeared that the activity based waste management practices mostly allowed learners to learn how to do waste management more than allowing them to find out more about the scope and nature of ii the problem of waste. This then resulted in learners talking more about what they were doing with waste than talking about what they knew about waste. There were differences in the way in which learners approached waste in the two cases. In the one case, Kingswood Junior School learners used waste artistically and carried out activities that allowed for better use of waste resources like paper while in the other School, Grahamstown SDA School, learners approached waste as a resource for making money. However, in both cases, learners appeared to enjoy the positive experiences of doing things that contributed to a cleaner environment and were of benefit to others and this gave them a sense of pride to share their experiences with others.
