- Description: Income Tax in South Africa is levied in terms of the Income Tax Act 58 of 1962 on taxable income, which, by definition, is arrived at by deducting from "gross income" receipts and accruals that are exempt from tax as well as deductions and allowances provided for in the Act. The Income Tax Act provides no guidance with regard to the taxation of illegal activities, except to prohibit the deduction of expenditure incurred in paying fines or in relation to corrupt activities, as defined. An analysis of the taxation of income derived from theft, fraud and prostitution and the deductibility of expenses relating to that income, is the question addressed in this thesis. In this thesis, an analysis was made of relevant case law in relation to the provisions of the Income Tax Act in an attempt to provide clarity. A brief comparison was also macie of American, United Kingdom and South African tax law. Similarities were found between the American, United Kingdom and South African tax regimes in relation to the taxation of income, but there appeared to be more certainty in America and the United Kingdom in relation to the deduction of expenses. The thesis concludes that recent case decisions have provided certainty in relation to income from illegal activities, but the tax status of the deduction of expenses remains uncertain.

- Description: Geomagnetically induced currents (GICs), resulting from adverse space weather, have been demonstrated to cause damage to power transformers at mid-latitudes. There is growing concern over possible GIC effects in the Southern African network due to its long power lines. Previous efforts to model the electric field associated with GICs in the Southern Africa region used a uniform ground conductivity model. In an effort to improve the modelling of GICs, GIC data together with Hermanus Magnetic Observatory geomagnetic field data were used to obtain a multilayered ground conductivity model. This process requires a definition of the network coefficients, which are then used in subsequent calculations. This study shows that GIC computed with the new network coefficients and the multilayered ground conductivity model improves the accuracy of GIC modelling. Then GIC statistics are derived based on the recordings of the geomagnetic field at Hermanus, the new network coefficients and ground conductivity model. The geoelectric field is modelled using the plane wave method. The properties of the geomagnetic field, their time derivatives and local geomagnetic indices were investigated to determine their characteristics in relation to the GIC. The pattern of the time derivatives of the horizontal geomagnetic field closely follow the rate of change of the north-south geomagnetic component rather than the east-west component. The correlation between the GIC and the local geomagnetic field indices was also investigated. The results show that there is a higher correlation between the GIC and the east-west components of the geomagnetic local indices than between the GIC and the north-south components. This corresponds very well with the orientation of the power lines feeding the power transformers at the South African Grassridge electrical substation GIC site. Thus, the geoelectric field driving the GIC at Grassridge is north-south oriented. Further, it is shown that the geomagnetic observation sites have a strong directional preference with respect to the Grassridge GIC site.

- Description: The geomorphology and dynamics of the Mfolozi River floodplain and estuary, located in the subtropical region of northern KwaZulu-Natal, South Africa, were considered with respect to existing models of avulsion and alluvial stratigraphy. The Mfolozi River floodplain may be divided into regions based on longitudinal slope and dominant geomorphic processes. Confinement of the Mfolozi River above the floodplain has led to the development of an alluvial fan at the floodplain head, characterized by a relatively high sedimentation rate and avulsion frequency, at a gradient of 0.10%. The lower floodplain is controlled by sea level, with an average gradient of 0.05%. Between the two lies an extremely flat region with an average gradient of 0.02%, which may be controlled by faulting of the underlying bedrock. Avulsion occurrences on the Mfolozi floodplain are linked to the two main zones of aggradation, the alluvial fan at the floodplain head, and toward the river mouth in the lower floodplain. On the alluvial fan, normal flow conditions result in scour from local steepening. During infrequent, large flood events, the channel becomes overwhelmed with sediment and stream flow, and avulses. The resulting avulsion is regional, and affects the location of the channel from the floodplain head to the river mouth. Deposits resulting from such avulsions contribute significantly to the total volume of sediment stored in the floodplain, and tend to persist for long periods after the avulsion. Contrastingly, on the lower floodplain, reaching of the avulsion threshold is not necessarily linked to large flood events, but rather to long-term aggradation on the channel that decreases the existing channels gradient while increasing its elevation above the surrounding floodplain. Resultant avulsions tend to be local and do not contribute significantly to the overall volume of floodplain alluvium.

- Description: This paper outlines the design of gPF, a fast packet classifier optimised for parallel execution on current generation commodity graphics hard-ware. Specifically, gPF leverages the potential for both the parallel classi-fication of packets at runtime, and the use of evolutionary mechanisms, in the form of a GP-GPU genetic algorithm to produce contextually opti-mised filter permutations in order to reduce redundancy and improve the per-packet throughput rate of the resultant filter program. This paper demonstrates that these optimisations have significant potential for im-proving packet classification speeds, particularly with regard to bulk pack-et processing and saturated network environments.

- Description: The educational reform policy in Namibia adopted the principles and practice of learner-centred education, a policy based on constructivist epistemology. This approach emphasises that learners are constructors of knowledge and that they must discover information and construct their own learning. Constructivist techniques require the use of critical thinking through learners’ active involvement in the learning process. The aim is for learners to use critical thinking to identify problems, ask questions, reason, examine and solve problems in real situations and make sound decisions. This approach provides learners with activities and experiences that stimulate them to learn to think for themselves and to ask questions. Therefore, teachers need to design activities that require learners to think critically and act independently through mastering these various modes of inquiry. The purpose of this study was to explore how the selected Grade 10 Life Science teachers understand and implement critical thinking in their teaching practice. I conducted the study in two secondary schools from the Omusati region in Namibia using a case study to gain insight into the implementation of critical thinking. Three data collection instruments: interviews, document analysis and class observations were used. The reason for conducting this study was to gain a better understanding of how teachers use various strategies to foster critical thinking skills in Life Science and the challenges they experience in teaching in secondary schools. The results of the study revealed that teachers have a theoretical understanding of what critical thinking implies and the role it plays in learning. They are also aware of the strategies used to develop critical thinking skills. However, these theoretical perspectives do not reflect in their teaching in that some of the strategies that the teachers used did not bring about meaningful learning. Learners are still required to recall factual knowledge, thus active involvement of the learners is limited. The study also revealed that there are specific issues that hamper the implementation of critical thinking, which include superficial understanding of learner-centered education, teacher-tell approach, overcrowded curriculum, inexplicit syllabus, lack of good examples from the textbooks and examinations, too short lesson periods, lack of language proficiency and lack of professional development. The findings indicate that despite the theoretical understanding of the teachers in this study, their actual practice of developing critical thinking skills is problematic. The study concludes that teachers should be encouraged to design better-structured activities in order to involve learners beyond just being listeners. In light of these findings, the study recognizes a need for ongoing in-service professional development to support teachers in modelling critical thinking to their learners and to teach them to think critically. The findings of the study will serve to inform both my and my colleague’s professional practice as advisory teachers with regard to what to focus on when advising and supporting the teachers in schools.

- Description: preprint , This paper reports on the writing of grade 7 learners in English as an additional language at four differently-resourced schools in the Eastern Cape Province, South Africa. Because grade 7 is the start of the senior phase of schooling, it is vital that learners achieve grade-level competence in the language used as medium of instruction. Learning outcome five which states that ‘the learner will be able to use language to think and reason, as well as access, process and use information for learning’ (Department of Education 2002) is particularly relevant. The primary research question asked what the writing practices in grade 7 additional languages were, and how these contribute to the development of learners’ writing. The findings were that literacy practices at all four schools privilege grammar exercises and personal, expressive writing. In terms of Cummins’s (1984) constructs of BICS (Basic Interpersonal Communicative Skill) and CALP (Cognitive Academic Language Proficiency), learners’ written competencies are mainly conversational (BICS). The personal expressive texts which predominate in learners’ writing have done little to develop a formal, impersonal academic register (CALP). Learners need to become familiar with the more abstract impersonal factual genres associated with disciplinary-based knowledge.

- Description: Trees provide a wide range of goods and services to rural households which, when incorporated into their livelihood strategies, help reduce their vulnerability to adversity. Governments and policy makers often ignore the contribution made by trees and consequently resources are focussed on cash crops and livestock. Villagers in the Eastern Cape and Limpopo Province, South Africa utilise a range of trees from home-gardens for various purposes, although predominantly for fruit and shade. Trees are either planted or actively retained in households' home-gardens. There were noticeable differences between the villages in the Eastern Cape and those in Limpopo Province, particularly with respect to the overall density of trees per hectare and the number of species per household, both being significantly greater in Limpopo Province. The five most preferred species were listed for each village, revealing a preference for exotic fruit trees in Limpopo Province and a mix of exotic fruit trees and shade trees in the Eastern Cape. Households also retained useful indigenous species, predominantly fruit-bearing species. A range of factors constrain tree growing in home-gardens and households engage in practices to grow and maintain their trees. Not all of these constraints and practices were significantly different between the various localities.

- Description: Women are subject to a number of societal recommendations about what it means to be an 'ideal' woman. These recommendations take the form of social scripts, constructing an idea of ideal femininity, which women must perform in order to be socially accepted and successful. 'Emphasized femininity', a white, Western, script of femininity is dominant and has been critiqued by feminists, social theorists, and individual women for the limits that it places on women's behaviour. As a result a number of alternative scripts of femininity have arisen. These scripts can provide alternatives to restrictive understandings of female sexuality and beauty - they can serve to challenge 'appropriate' feminine behaviour and hence allow women to live more freely. Raunch femininity is a contemporary alternative that uses sexually explicit public performance, and encourages specific body and dress norms, in an attempt to challenge the norms of emphasized femininity. This thesis looks at raunch femininity, specifically its norms of sexuality and beauty, in the hopes of understanding what the effects of such a script are on women's behaviour. Theoretical understandings and explanations of women's lives are often contradicted by reports that women provide of their lived experiences. For this reason, this thesis investigates the lived experiences of women who self-identify as subscribers to this script in order to assess to what extent superficial expressions of freedom have deeper effects on women's freedom. The tension between theory and empirical reports is evident. However, in many cases, the reports of research participants reveal that the script of raunch femininity, like other scripts of feminine behaviour, has its own limits that women must abide with in order to be accepted. This thesis argues that these limits outweigh the benefits of this script. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: The problems of illiteracy in health contexts have been well documented in the literature and include such serious repercussions as medication non-compliance and failure to seek medical help during the course of an illness. The Rapid Estimate of Adult Literacy in Medicine (REALM) is a standardised health literacy test developed in the United States that has been previously administered and researched in South Africa (Lecoko, 2000). It is an objective vocabulary test, designed as a screening instrument to identify the health literacy levels of patients in clinics, which uses item recognition of 66 health-related words. Lecoko found that, in a South African setting, only 8 out of the 66 words in the US-developed test could be deemed acceptable. Therefore, the current study focused on the principled relexicalisation of the REALM, using words gathered from health information and promotional texts in local clinics, hypothesising that this would improve its applicability. After administration to a statistically similar group of respondents, the number of acceptable words on the test increased from eight to 38. Thus it is concluded that principled relexicalisation may be one way of improving the applicability of standardised health literacy tests to local populations and settings. However, the limitations of standardised tests may prove to be a significant barrier overshadowing the value of relexicalisation.

- Description: The aim of this research was to assess three hierarchical aspects of alga-grazer interactions in intertidal communities on a small scale: spatial heterogeneity, grazing effects and spatial stability in grazing effects. First, using semivariograms and cross-semivariograms I observed hierarchical spatial patterns in most algal groups and in grazers. However, these patterns varied with the level on the shore and between shores, suggesting that either human exploitation or wave exposure can be a source of variability. Second, grazing effects were studied using manipulative experiments at different levels on the shore. These revealed significant effects of grazing on the low shore and in tidal pools. Additionally, using a transect of grazer exclusions across the shore, I observed unexpected hierarchical patchiness in the strength of grazing, rather than zonation in its effects. This patchiness varied in time due to different biotic and abiotic factors. In a separate experiment, the effect of mesograzers effects were studied in the upper eulittoral zone under four conditions: burnt open rock (BOR), burnt pools (Bpool), non-burnt open rock (NBOR) and non-burnt pools (NBpool). Additionally, I tested spatial stability in the effects of grazing in consecutive years, using the same plots. I observed great spatial variability in the effects of grazing, but this variability was spatially stable in Bpools and NBOR, meaning deterministic and significant grazing effects in consecutive years on the same plots. Both the significance in grazing effects and spatial stability depended on the level of resolution (species, functional, biomass) at which the algal assemblage was evaluated, suggesting hierarchical variability. In order to be able to predict spatial variability in the effects of grazers in the upper eulittoral zone using biotic and abiotic micro- and macrofactors, a conceptual model was proposed, based on data from several multiple-regressions. This linked the interactions among three elements: idiosyncratic heterogeneity, micro and macrofactors. This suggests that spatial variability can be a product of these factors, while spatial stability can be caused by the same or different combinations of factors. In conclusion, grazing and other ecological phenomena must be studied hierarchically, not only through spatiotemporal scales, but also at different levels of resolution, as these also influence our perception of patterns.

- Description: This study was conducted as a case study at the rural Ethridge Junior Secondary School which is located in the Eastern Cape Province of South Africa. The aim of the study was to investigate how school gardens could be used to teach environmental activities in the Technology Learning Area at senior phase. The study examined how environmental activities in the school garden can be used to develop technological concepts and knowledge and for developing technological problem-solving abilities. Furthermore, it examined the relationship between technology, society and environment, and how structural and socio-cultural factors influence the use of environmental activities in the school garden. The overall approach was a case study. The data was generated using qualitative methods such as interviews, observation, workshops and document analysis of learners’ work. Of all the research tools used, the interviews and observations were the most fascinating and informative methods. The study focused on various activities undertaken by Grade 8 learners in their Technology Learning Area. These activities were compost making, planting and irrigating. The study showed how learners from poor rural homes can use available resources and suitable technology processes to plant vegetables. In terms of resources, virtually all resources used in the study were free, sourced locally and/or borrowed. This indicated that even in poor, rural areas materials are available to make structures and complete activities. In terms of available suitable technology, learners in the study explored the use of old car tyres for planting containers that can be easily transported. They also, using easily available resources such as tin cans, explored how to design and construct an effective, low-water consumption, low cost irrigation devise. The study explored the achievement of Learning Outcomes (LO) using the school garden. This study uses the school garden as a teaching aid to achieve the three main LO’s in the Technology Learning Area (LA). This study has also indicated that LO’s are sometimes intertwined, that is to say that more than one can be achieved at the same time. The three activities (compost making, planting and irrigation) were used to attain the required LO’s. The study indicates that LO 1 (related to applying technological processes and skills ethically and responsibly) can easily be achieved by designing a compost box and a compost heap, making them and evaluating the process. LO 2 (related to understanding and applying relevant technological knowledge) could easily be achieved in the irrigation activity, and LO 3 (related to demonstrating interrelations between science, technology, society and environment) could easily be attained in both compost making and planting. The study also showed that curriculum activities, such as those used in this study, are influenced by socio-cultural and structural factors that influence the curriculum contextualizing process. The main findings of the study are captured in five analytical statements. These form the basis for a set of recommendations to inform the use of school gardens as a resource for technology teaching in Ethridge Junior Secondary School, and possibly for other rural schools.

- Description: The Bonn Declaration, approved by the 900 participants at the UNESCO World Conference on Sustainable Development, differs from other conference declarations in that it is the first declaration to deal exclusively with education for sustainable development. It received input from official State representatives and, perhaps because of that, it is somewhat less provocative than some nongovernmental or university-sponsored declarations. Also, it actually sets out, with some authority, an agenda for UNESCO, the manager of the UN Decade of Education for Sustainable Development. Though some may question the usefulness of conference declarations, history shows that such declarations do have at least some guiding power in that they provide common starting points for deliberation on possible changes at national and international levels.

- Description: Since the demise of the Berlin Wall and communism, many African countries have adopted a Western-model democracy as a system of governance. However, the media has not been liberalised to reflect this new discourse as constraints in many African countries pertaining to press freedom still exist. The internet appears to have the potential to challenge the political power of governments (Tsagarousianou, 1998:167). It has been posited that it has the potential to offer more platforms for information especially in the case of restrictive media environments. This study set out to investigate the impact of on-line publishing in Malawi. It explored how the emergence of this new form of publishing through the internet has affected the public sphere, democracy and press freedom in Malawi. The main focus was the level of press freedom at on-line newspapers as compared to traditional newspapers. It used the public sphere theory and literature on the internet as a technology of freedom as its theoretical framework. Using a case study approach by focusing on two newspapers; Nyasatimes on-line and Daily Times, the study used the coup plot coverage in May 2008 in Malawi by both newspapers as reference for the measurement of the level of press freedom. The study used qualitative content analysis and semi-structured interviews as its research methods. The research revealed that Nyasatimes enjoys more freedom to publish and therefore appears to have more press freedom than its more traditional counterpart. However, Nyasatimes also faces some unique challenges. The findings also revealed that press freedom in Malawi is not only affected by government through legislation but other factors and players as well play a central role in determining the level of press freedom for traditional media. The study therefore concludes that despite the internet’s ability to transcend local regimes of authority and censorship pertaining to press freedom, the challenges facing traditional media still need to be addressed as it is the primary source of information for most people in Malawi with on-line newspapers being simply supplementary.

Human-river relationships in the Kat River catchment and the implications for integrated water resource management (IWRM) : an exploraratory study

- Description: Through out this study ‘relational scenarios’ were seen as the possible outcomes of the expression of human-river relationships in a catchment. Working within Inglis’s (2008, pg. 10) comment that ‘the Human World Relationship is expressed through a person’s views and behaviour towards the natural world, which can be either constructive or destructive’, two relational scenarios were selected to represent these two predicted outcomes of human-environment (or in the case of this thesis human-river) relationships: IWRM, seen as constructive and mutually beneficial to both the social and ecological system, and the Tragedy of the Commons, seen as destructive and parasitic in nature. In respect to this assertion, a conceptual framework or model was developed and used to guide the inductive process of this research. Through a social survey (administered via semi-structured interviews) of stakeholders (water-users) in the Kat River Catchment, Eastern Cape, South Africa, social attitudes towards the Kat River were explored. These attitudes were considered as variables that relate to the expression of ‘Human World Relationships’ namely ‘values and behaviour’ (Inglis, 2008, pg. 10). The findings of this thesis confirm that attitudes are influential components of human-river relationships in the Kat River Catchment. It was observed from the findings that the attitudes individuals have towards the Kat River have the potential to influence the ways people interact with the River and its associated resources, and are in turn influenced by the condition of the River and connections people have or make with the River within their daily lives. Such relationships in turn affect the management of the River and its water resources and influence how individuals approach water-related issues and undertake the associated activities. Given this understanding it was then proposed that attitudes could provide information that enables the prediction of likely ‘relational scenarios’ (IWRM or the Tragedy of the Commons) in a catchment. The findings appear to support this proposal, and three main attitude groups (utilitarian, associative and dissociative) were identified and used to further the discussion into how this knowledge could be used in predicting possible relational scenarios based on human-river relationships. Further exploration of the identified attitude groups suggested that these variables are significantly influenced by environmental ethics and place attachment (present in the community) and a series of guiding frameworks were developed to facilitate the exploration of the attitude groups relative to these concepts. The frameworks were generated from the hypothesis that knowledge of attitude groups in a catchment, in connection with the relative degrees to which moral values and worldviews are expressed, could provide insight into the readiness of a catchment system for the implementation of IWRM and/or the facilitative steps needed to shift the influence of unfavourable attitude groups (i.e. dissociative attitudes). Such steps would most likely involve extensive educational, awareness and capacity building programs. Finally, given the above theoretical frameworks, inductively developed from the findings of the social survey and related literature, the conceptual model was reevaluated and extended to include the thesis findings and hypotheses. It is suggested that in a catchment where there is a balance between the expression of utilitarian and associative attitude groups, then there is a high probability of finding present evidence of mutually beneficial human-river relationships already in play, as well as ‘fertile soil’ for the promotion of IWRM and philosophies and skills that generate such relationships. Alternatively in an area with a strong expression of dissociative attitudes, it is more likely to find evidence of destructive, more parasitic-like relationships being expressed, and a lack of commitment and interest in being involved in changing the status quo. It is likely that where both associative and dissociative attitudes are present there will be an overlap of elements of both scenarios – a situation that is probable in most catchments – depending on the strength of expression of either attitude group the balance will shift (be shifting) between the two relational scenarios.

- Description: Through out this study ‘relational scenarios’ were seen as the possible outcomes of the expression of human-river relationships in a catchment. Working within Inglis’s (2008, pg. 10) comment that ‘the Human World Relationship is expressed through a person’s views and behaviour towards the natural world, which can be either constructive or destructive’, two relational scenarios were selected to represent these two predicted outcomes of human-environment (or in the case of this thesis human-river) relationships: IWRM, seen as constructive and mutually beneficial to both the social and ecological system, and the Tragedy of the Commons, seen as destructive and parasitic in nature. In respect to this assertion, a conceptual framework or model was developed and used to guide the inductive process of this research. Through a social survey (administered via semi-structured interviews) of stakeholders (water-users) in the Kat River Catchment, Eastern Cape, South Africa, social attitudes towards the Kat River were explored. These attitudes were considered as variables that relate to the expression of ‘Human World Relationships’ namely ‘values and behaviour’ (Inglis, 2008, pg. 10). The findings of this thesis confirm that attitudes are influential components of human-river relationships in the Kat River Catchment. It was observed from the findings that the attitudes individuals have towards the Kat River have the potential to influence the ways people interact with the River and its associated resources, and are in turn influenced by the condition of the River and connections people have or make with the River within their daily lives. Such relationships in turn affect the management of the River and its water resources and influence how individuals approach water-related issues and undertake the associated activities. Given this understanding it was then proposed that attitudes could provide information that enables the prediction of likely ‘relational scenarios’ (IWRM or the Tragedy of the Commons) in a catchment. The findings appear to support this proposal, and three main attitude groups (utilitarian, associative and dissociative) were identified and used to further the discussion into how this knowledge could be used in predicting possible relational scenarios based on human-river relationships. Further exploration of the identified attitude groups suggested that these variables are significantly influenced by environmental ethics and place attachment (present in the community) and a series of guiding frameworks were developed to facilitate the exploration of the attitude groups relative to these concepts. The frameworks were generated from the hypothesis that knowledge of attitude groups in a catchment, in connection with the relative degrees to which moral values and worldviews are expressed, could provide insight into the readiness of a catchment system for the implementation of IWRM and/or the facilitative steps needed to shift the influence of unfavourable attitude groups (i.e. dissociative attitudes). Such steps would most likely involve extensive educational, awareness and capacity building programs. Finally, given the above theoretical frameworks, inductively developed from the findings of the social survey and related literature, the conceptual model was reevaluated and extended to include the thesis findings and hypotheses. It is suggested that in a catchment where there is a balance between the expression of utilitarian and associative attitude groups, then there is a high probability of finding present evidence of mutually beneficial human-river relationships already in play, as well as ‘fertile soil’ for the promotion of IWRM and philosophies and skills that generate such relationships. Alternatively in an area with a strong expression of dissociative attitudes, it is more likely to find evidence of destructive, more parasitic-like relationships being expressed, and a lack of commitment and interest in being involved in changing the status quo. It is likely that where both associative and dissociative attitudes are present there will be an overlap of elements of both scenarios – a situation that is probable in most catchments – depending on the strength of expression of either attitude group the balance will shift (be shifting) between the two relational scenarios.

- Description: This paper investigates the feasibility of developing a CSP to Python translator using a concurrent framework for Python. The objective of this translation framework, developed under the name of Hydra, is to produce a tool that helps programmers implement concurrent software easily using CSP algorithms. This objective was achieved using the ANTLR compiler generator tool, Python Remote Objects and PyCSP. The resulting Hydra prototype takes an algorithm defined in CSP, parses and converts it to Python and then executes the program using multiple instances of the Python interpreter. Testing has revealed that the Hydra prototype appears to function correctly, allowing simultaneous process execution. Therefore, it can be concluded that converting CSP to Python using a concurrent framework such as Hydra is both possible and adds flexibility to CSP with embedded Python statements.
