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

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

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

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

- Description: This thesis examines the political implications of the integrated development planning process embarked upon by South African municipalities in the period 1998-2004. Through the use of case study methodology that focuses on the Eastern Cape municipalities of Buffalo City and Ngqushwa, the conventions of municipal planning are examined. This inquiry into municipal planning draws upon official government documents and reports and publications from the nongovernment sector. The thesis is particularly focused on the claims made in policy documents and related secondary sources and compares these to more critical reports and publication as well as the author's personal experience of the integrated development planning process. Of key interest is the possibility that planning serves political interests and the material needs of an emerging municipal elite and that this is seldom acknowledged in official planning documentation or government sanctioned publications on the topic. The primary findings of the thesis are as follows: • That the 'reason' of expert policy formulations that accompanied integrated development planning has weakened political economy as a prism of understanding and separated itself from the institutional reality of municipal government • That the dominant critique of planning and other post-apartheid municipal policy is concerned with the triumph of neoliberalism but this critique, while valid, does not fully explain successive policy failures especially in the setting of Eastern Cape local government • That function of policy and its relationship to both the state and civil society is usually understood only in the most obvious sense and not as an instrument for wielding political power • That planning still derives much of its influence from its claim to technical rationality and that this underpinned the 'authority' of the integrated development planning project in South Africa and reinforced its power to make communities governable.

- Description: Rural schools generally find it hard to function effectively for a variety of reasons, and managing and leading these schools brings additional challenges. This study explored the role of the principal in an academically successful rural school in Namibia. It drew on leadership theory and findings from related studies to make sense of this particular case of leadership against the odds. Using the interpretive orientation, the research explored selected organisation members’ perceptions of the principal’s leadership through semi-structured interviews. The study found that the actions and attitudes of the leader had a significant influence on the school’s performance. The manner in which the principal conducted himself, the shared vision he encouraged and his insistence on associating with all stakeholders involved in education, were instrumental in the organization’s positive achievements. The principal was shown as committed and a leader with good interpersonal working relationships. The study also revealed that this principal was both a person- and taskoriented leader, and closely resembled the ideals of transformational leadership. This study further found that, through the principal’s instructional leadership, teaching and learning are seen as the core of the school’s activities. Finally, the principal’s leadership role opens the school to the community and results in strong and mutually beneficial relationships between the school and its community.

- Description: After careful review of all the relevant literature pertaining to motivation, performance management and compensation in the form of incentives, this thesis focuses primarily on determining whether a statistically significant relationship exists between individual needs and the choice of an incentive scheme option. The secondary aims of the research are to determine whether: A relationship exists between the job grade of an individual and the choice of an incentive scheme. A particular incentive scheme option is preferred by the employees in The South African Breweries (SAB). A particular preference exists, and if so, to make recommendations to SAB for consideration as alternatives to their existing incentive scheme options. After collation of the survey data from the respondents in the sample, the analysis and discussion of the results determined that no significant relationship exists between individual needs and the choice of an incentive scheme option. It was, however, determined that a significant relationship exists between the grade of the employees in SAB and their choice of an incentive scheme. 81% of all respondents indicated a desire for shares as an option in their Short Term Incentives (STI) which indicates a desire for shares in some form or another and may well indicate a level of confidence and commitment by the employees to the organisation. Although the research hypothesis was not proven, significant insights into remuneration within SAB was obtained, which has resulted in recommendations being made for further research into the option of shares in some form or another in the organisation. A further recommendation for SAB is to consider some form of share options for all employees in the organisation. As many other organisations that are performing at remarkable levels attest this performance to share ownership and the behaviour that emanates from it, it would be in the interests of SAB to further investigate the issue as it may improve performance, ownership and retention within the company.

- Description: This research investigates the relationship between leadership styles and different types of organisational commitment in Eskom Eastern Region. The literature provided discusses the leadership and organisational commitment. Information was gathered, using two instruments, from a sample of 86 leaders and 334 raters. The Multifactor Leadership Questionnaire, which was formulated from Bass and Avolio’s (1997) Full Range Leadership Development Theory, was used to determine leadership style within the organisation. Employee commitment was captured using Bagraim’s (2004) Organisational Commitment, a South African adaptation of Meyer and Allen’s (1997) Three-Component Model of employee commitment. Leadership was identified as the independent variable and organisational commitment as the dependent variable. Data obtained from each of the research instruments was then statistically analysed. Two-tailed correlation analysis showed that although the relationship is not strong, there is a positive relationship between the transformational leadership behaviours and commitment (affective commitment, continuance commitment and normative commitment). The correlation analysis also indicates a weak, but significant, positive relationship between transactional leadership behaviours and continuance commitment. However, no statistically significant correlation was found between transactional leadership behaviours and affective commitment as well as between transactional leadership behaviours and normative commitment. The correlation results showed a weak, but significant, negative correlation between laissez-faire leadership behaviours and affective commitment. There was no statistically significant correlation between laissez-faire leadership behaviours and continuance commitment as well as between laissez-faire leadership behaviours and normative commitment. Overall findings from this study suggest that transformational and transactional leadership behaviours do play important roles in determining levels of affective commitment, continuance commitment and normative commitment. These findings also reveal that the laissez-faire leadership behaviour had a negative relationship with affective commitment. This research therefore adds a new dimension to the body of literature that will help researchers’ efforts to understand the relationship between leadership style and organisational commitment. As this research takes place in the South African context, it contributes to the bank of findings relating to the development of organisational commitment.

- Description: This study analysed the representation of South African women politicians in the Sunday Times’ election news during the 2004 Presidential and general elections, by drawing on perspectives from cultural studies, the constructionist approach to representation and the sociology of news production. Using content analysis and critical discourse analysis, the study found that very few women politicians were used as news actors/sources in the Sunday Times, and that when women politicians were figured, the paper tended to present them in ways that serve to sustain women’s subordinate status in society. Using content analysis, the study analysed 106 news items published between January 1, 2004 and April 30, 2004, and found that of all the 588 identifiable news actors/sources counted, 135 were women and 453 were men. Of these, only 7.67% (or 26) were women politicians and 92.33% (or 313) were men politicians. On average however, the amount of words allocated to a woman politician was more than that allocated to a man politician. The discourse analysis also revealed how the Sunday Times managed to reproduce textually the hegemonic power relations between women and men, by constructing different subject positions for women politicians and men politicians, which generally tended to be negative and positive respectively. In the representation of women politicians, the study revealed patterns that tended to ascribe them negative personality traits, accentuate their passivity and dependency on men, and construct them as incompetent political leaders. This study’s conclusions pose a challenge to the role of the national newspaper in the transformation of gender relations and the promotion of equal access to political and decision-making positions, and to the news media. News discourse, as a social practice, both determines and is determined by the social structure in which it is produced. By systematically reproducing subordinate subject positions for women in the news, the Sunday Times helps to further women’s subordinate status in society. Particularly, as part of the broader social cultural context that is embedded in patriarchal and gender ideologies, the Sunday Times does not merely reflect but actively and effectively constructs the reality it claims to be representing.

- Description: This thesis is an investigation into the socio-economic constraints that influence the decisions of tuberculosis sufferers in the health seeking process and therapeutic management of tuberculosis in Grahamstown, the Eastern Cape. It is shown that structural violence influences experiences and perceptions of tuberculosis at all levels. Management of tuberculosis in the formal health sector is explored at local levels and related to national and global strategies of health care. The role of health workers, and particularly voluntary health workers, is explored and it is shown that they work within a context of growing burden of sickness and co-infections and a lack of government commitment to deal with increasing TB and HIV incidences. Kleinman’s notion of explanatory models is explored and it is evident that although knowledge of the aetiology of tuberculosis is well-known to patients and general members of the communities, they are nevertheless victims of increased stigmatisation and marginalisation as a result of illness. The importance of social support in curing tuberculosis is explored using Janzen’s concept of therapy managing groups. Social capital is a fundamental component in adhering to biomedical therapy, but is commonly weak among the structurally poor. The availability of temporary social grants for people living with TB influences health seeking behaviour. In a context of structural poverty the sick are faced with what Nattrass terms “perverse incentives”, having to choose between the right to health and the right to social security, both guaranteed in the South African Constitution, for him/herself and dependants. Although adherence to biomedical therapy is essential in curing tuberculosis, it is shown throughout this thesis that ignoring wider structural causes of disease limits the patient’s ability to get well. The ethnography shows that the right to health is a social and economic right which is not the reality for most South Africans.

- Description: The existence of an occupational health and safety policy is believed to be evidence of management accepting their occupational health and safety role in terms of the Occupational Health and Safety Act. It is accepted that this results in management ensuring the provision of a safe workplace. Despite the emphasis in legislation (the Occupational Health and Safety Act) on the need for management to implement comprehensive occupational health and safety policies, there is a lack of research on the implementation and efficacy of occupational health and safety policies in the workplace. This study investigates the efficacy with which management carries out their occupational health and safety duties and responsibilities when implementing the provisions of an occupational health and safety policy in the workplace. A number of factors are essential to the efficient performance of management in this regard. These factors include managerial commitment, practices and strategies; communication practices and structures; training initiatives and information; the extent of employee and trade union involvement; and the infrastructure of the organisation. This research study is primarily qualitative in nature. Semi-structured interviews were the primary tool used by the researcher to collect the data. The case-study research method was employed to assist the researcher in collecting the data. The participants involved in the research were selected using the principles of strategic informant sampling and expert choice sampling. The participants consisted of a sample of management, employees and shop stewards. The research findings indicate that firstly, the presence of occupational health and safety policies, practices, strategies and systems in the workplace do not automatically result in reduced hazards, accidents or deaths in the workplace. Secondly, the participation schemes and the communication practices put in place by management are weak. The reason for their weakness is their ineffective implementation by management and use by employees and the trade union. Thirdly, management has a definite impact on the involvement, attitudes and actions of the employees and the trade union in occupational health and safety issues. Fourthly, there is an unequal partnership between management and employees as a result of the educational differences regarding occupational health and safety between them. The outcome is that management and employees are faced with numerous challenges in relation to occupational health and safety. Contributing to this challenge is a lack of sufficient resources allocated to training, resulting ultimately in the ineffective monitoring of occupational health and safety in the workplace. The existence of occupational health and safety structures and systems does not provide the essential evidence to suggest that their mere presence makes a difference to the workplace safety level. However, through more co-operation and participation by all the parties, these structures and systems have the potential to be effective. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The role of aardvarks (Orycteropus afer) as ecosystem engineers in arid and semi-arid landscapes of South Africa

- Description: Arid and semi arid environments are characterised by extreme fluctuations in temperature and low rainfall which present significant challenges to the animals inhabiting these areas. Mammals, such as aardvarks (Orycteropus afer, Pallas 1766), excavate burrows in order to avoid predators and climatic extremes and are termed “ecosystem engineers” as they physically modify their environment and in doing so create new habitats and alter the availability of resources to other species. In this study I assessed the microhabitat conditions (maximum and minimum temperature, relative humidity and seed abundance) of aardvark burrows in relation to paired control sites. In addition, I evaluated the use of aardvark burrows by other vertebrate and invertebrate species and investigated the impact of aardvark burrow mounds on landscape scale floristic diversity. Maximum temperatures were significantly lower (p < 0.05) and minimum temperatures and midday humidity were significantly higher (p < 0.05) inside the burrows at the three study sites, Kwandwe Private Game Reserve (Kwandwe), Mountain Zebra National Park (MZNP) and Tswalu Kalahari Reserve (Tswalu). There were no significant differences between the concentration of seeds, the average numbers of unique individual small mammals, trap success or small mammal species richness recorded inside the burrows compared to outside (p > 0.05). At all three sites, small mammal species diversity was higher in the burrows but this result was also not significant (p > 0.05 for all). Trap success and the number of individuals captured was higher at Tswalu than the other two sites (p < 0.05 for both). The different methods used in this study revealed a total of 25 mammal, seven bird, one amphibian and six reptile species utilising aardvark burrows. There were significant differences in insect community assemblages between the burrows and open control areas at Kwandwe and Tswalu (p < 0.05 for both) but not at MZNP (p > 0.05). The parasitic guild was more prominent inside the burrows than outside but their abundance was not as high as anticipated, possibly due to the placement of traps closer to the burrow entrances than the sleeping chambers. The complex structure of the burrows prevented the placement of traps in close proximity to the sleeping chambers. As expected, the amount of bare earth was significantly higher on active and recently abandoned burrow mounds compared to the old burrow mounds and reference plots at all three sites (p < 0.05 for all), with the exception of the active burrows at Tswalu. Overall, the different plot types were characterised by significantly different plant communities during all the seasons at MZNP, during three of the seasons at Kwandwe and only during winter at Tswalu. The total species richness recorded on the reference plots was higher than on the burrow mounds at all three sites. However, species diversity on the reference plots was not significantly higher than the burrows at any of the sites (p > 0.05 for all sites). Although the results were not significant, the overall species diversity at a site level was greater than the reference patches at Kwandwe and Tswalu (p > 0.05 for both). Aardvarks fulfil the criteria of a significant ecosystem engineer and their presence in arid and semi-arid environments is likely to be critical to the survival of other individual organisms and species, particularly when alternative burrowing animals are either absent or restricted in their activities. Thus, aardvark populations should be considered a conservation priority in arid and semi-arid ecosystems.

- Description: Fundamental processes underpinning the biotransformation of coal by fungal biocatalysts have been intensively investigated, however, limited large-scale industrial applications using such systems have been reported. The un-anticipated sporadic growth of Cynodon dactylon on the surface of un-rehabilitated discard coal dumps has been noted and this was found to be coupled with the breakdown of coal into a humic soil-like material in the top 1.5 metres of the dumps. Extensive fungal growth was observed to be associated with the Cynodon dactylon root system and examination of plant roots indicated the presence of mycorrhizal fungi. Analysis of the Cynodon dactylon plant roots around which coal biotransformation was occurring confirmed the presence of arbuscular mycorrhizal colonisation with the species Glomus clarum, Paraglomus occultum, Gigaspora gigantea and Glomus mosseae identified to be associated with the plants. Further molecular characterisation of non-mycorrhizal rhizospheric fungi showed the presence of fungal species with coal-degrading capabilities that most likely played a role in the coal biotransformation observed. The discard coal dump environment was simulated in pot and column studies and coal biotransformation was reproduced, with this process enhanced by the addition of mycorrhizal and non-mycorrhizal rhizospheric fungal inocula to the environment. Mycorrhizal and non-mycorrhizal species in the inoculum were re-isolated from the simulated environment fulfilling a number of Koch’s postulates and indicating a causal role in the biotransformation of coal. An inversion of conventional mycorrhizal colonisation was demonstrated in this system with reduction in extraradicular presence and an increase in intracellular colonisation compared to soil controls. A descriptive model was formulated suggesting a two-part fungal system involving organic carbon and nutrient exchange between the plant, mycorrhizal fungi and non-mycorrhizal coal-degrading rhizospheric fungi ultimately resulting in the biotransformation of coal. The biotransformation observed was comparable to reports of “rock-eating fungi”. Results suggest that the biological degradation of coal in situ with the production of a soil-like substrate could provide a feasible method of discard coal dump rehabilitation as well as provide a humic-rich substrate that can be utilised in further industrial applications.

- Description: This investigation looks at the role played by school-based studies in the development of reflective practice among student teachers at a Namibian college of education. Literature reviewed indicates that reflective practice helps teachers continually grow and enhance their professional insights and practices. The study focused on the perceptions and experiences of a group of teacher educators, support teachers and student teachers involved in a particular teacher education programme. A case study was chosen, and built up using an interpretive paradigm. This enabled the researcher to make meaning of information often taken for granted. Triangulation was used to ensure the development of as broad and authentic a picture of the case as possible. Key findings reveal that despite claims that Namibia’s three-year Basic Education Teacher Diploma programme (BETD) is explicitly designed to facilitate the development of critical reflective and reflexive practice in student teachers, the way in which aspects of the programme are implemented frequently undermines this design intention. A lack of careful and explicit mentoring on the importance of reflection for enhancing teaching, plus a measure of distrust between student teachers and teacher educators prevents college students from fully exploiting the opportunities afforded by school-based studies for the development of reflective skills.

- Description: This study uses a systems thinking perspective to explore the role and meaning of participation, capacity development and project sustainability in the Zimbabwe Secondary Teacher Training Environmental Education Project (St²eep). Since there was no consistent critical reflection upon the different assumptions that underpin these important aspects of St²eep in the original project design, this study aims to articulate a theoretical framework for guiding the project. St2eep is a donorfunded project, located in the Ministry of Higher and Tertiary Education in Zimbabwe that seeks to integrate environmental education across the curriculum of secondary teacher education. The study first develops a theoretical framework drawing on systems thinking. In particular it uses the holistic and constructivist perspectives embedded in systems thinking to describe a number of analytic frameworks that are used as a guide to investigate participation, capacity development and project sustainability in the St²eep case study. The research methodology comprises a qualitative case study approach, which contains elements of an instrumental, evaluative and critical case study. Data-collection methods include document analysis, focus group discussions, focus group interviews, semi-structured face-to-face interviews and participant observation. Data analysis follows the constant comparative method of coding and categorising data as outlined by Strauss and Corbin (1998). The outcomes of this research show that participation processes in St²eep evolve around the interactions between a political dimension and a learning dimension. The political dimension relates to giving the project stakeholders a critical voice, allowing them to shape the project and involving them in the decision-making process. This approach has fostered an ongoing learning process in a small team of committed stakeholders based on the principles of collaborative learning, team learning and action research. Participation was shown to enhance capacity-development processes at individual and institutional level by the provision of support through learning teams, and by the renegotiation of responsibilities and power relations between lecturers involved in St²eep, donor representatives and college administrations. The strong operational role of the donor organisation was seen as a serious threat towards individual and institutional capacity development since it creates a functional but artificial and independent project system within the college system and takes over any local institutional support structure that it might seek to develop. Fostering continuous learning and capacity development, St²eep’s participatory approach was shown to contribute to a better understanding of the interconnectedness of factors that influence future sustainability of the project and the implementation of environmental education. This has assisted in the development of different scenarios on the sustainability of the project. The research shows that the project-ustainability planning process draws directly from St²eep’s ongoing learning process, with individual and institutional capacity development featuring strongly in the different scenarios, and with the external context such as the economic situation and the low priority of environmental education being recognised as important factors that need to be considered. Drawing on the findings from the case study, this study makes a tentative recommendation that donor organisations should focus more on capacity-development initiatives and avoid taking on a strong operational role in project activities. The research also recommends that there is need for a deliberate focus on both the political and learning dimensions of the participation process in order to foster local ownership. Making the learning aspect much more central in St²eep is presented as a possible strategy for motivating a larger number of college lecturers to become involved in the project and the implementation of environmental education. The study also urges St²eep to combine the different scenarios that have emerged during the project sustainability planning process and to focus on the benefits that stakeholders want to see sustained.

- Description: This study uses a systems thinking perspective to explore the role and meaning of participation, capacity development and project sustainability in the Zimbabwe Secondary Teacher Training Environmental Education Project (St²eep). Since there was no consistent critical reflection upon the different assumptions that underpin these important aspects of St²eep in the original project design, this study aims to articulate a theoretical framework for guiding the project. St2eep is a donorfunded project, located in the Ministry of Higher and Tertiary Education in Zimbabwe that seeks to integrate environmental education across the curriculum of secondary teacher education. The study first develops a theoretical framework drawing on systems thinking. In particular it uses the holistic and constructivist perspectives embedded in systems thinking to describe a number of analytic frameworks that are used as a guide to investigate participation, capacity development and project sustainability in the St²eep case study. The research methodology comprises a qualitative case study approach, which contains elements of an instrumental, evaluative and critical case study. Data-collection methods include document analysis, focus group discussions, focus group interviews, semi-structured face-to-face interviews and participant observation. Data analysis follows the constant comparative method of coding and categorising data as outlined by Strauss and Corbin (1998). The outcomes of this research show that participation processes in St²eep evolve around the interactions between a political dimension and a learning dimension. The political dimension relates to giving the project stakeholders a critical voice, allowing them to shape the project and involving them in the decision-making process. This approach has fostered an ongoing learning process in a small team of committed stakeholders based on the principles of collaborative learning, team learning and action research. Participation was shown to enhance capacity-development processes at individual and institutional level by the provision of support through learning teams, and by the renegotiation of responsibilities and power relations between lecturers involved in St²eep, donor representatives and college administrations. The strong operational role of the donor organisation was seen as a serious threat towards individual and institutional capacity development since it creates a functional but artificial and independent project system within the college system and takes over any local institutional support structure that it might seek to develop. Fostering continuous learning and capacity development, St²eep’s participatory approach was shown to contribute to a better understanding of the interconnectedness of factors that influence future sustainability of the project and the implementation of environmental education.

- Description: This study was conducted in two rural villages in South Africa with the purpose of investigating the safety-net role of non-timber forest products (NTFPs). The use of NTFPs as a safety-net is reported as a common feature of rural livelihoods however empirical data supporting this function is limited. Therefore, policy makers and land-use planners underappreciate the probable role and consequent value of the safety-net function. The findings show that poor, rural households are vulnerable to a range of risks. Over a two year period 100% of households reported experiencing crises including unexpected idiosyncratic risks (e.g. illness, retrenchment, crop failure and death) as well as expected expenses and periods of vulnerability (e.g. the payment of school fees and seasonal crop shortfalls). Households are prone to these risks irrespective of wealth or gender of the de jure household head. To secure their livelihoods households in both villages rely on a variety of livelihood strategies including waged labour (53%), self-employment (30%), government grants (60%), arable agriculture (56%), animal husbandry (64%) and the use (100%) and sale (22%) of NTFPs. In terms of the proportion of households involved, the findings suggest land-based strategies make an important contribution. Formal employment and old-age pensions distinguish wealthy households from poor and allow for investments in assets and saving schemes (62%). In response to the risks experienced households employed a variety of coping strategies. Generally the most commonly used strategies were kinship (85%), reduced household spending (72%), changes to food consumption and saving (72%) and relying on NTFPs (70%). Kinship and NTFPs show no differences for wealth or gender of the de jure household head. The remaining strategies are influenced by wealth. The use of NTFPs as a safety-net manifested predominantly through the increased use of products, then the substitution of commercial goods by NTFPs and lastly through the sale. Of those using NTFPs as a rural safety-net 41.4% used of wild foods, 40% used medicinal plants, 25.7% substituted paraffin with fuelwood, 10% sold fuelwood and 8.6% sold other products.

- Description: Many research papers have documented the positive relationship between the slope of the yield curve and future real economic activity in different countries and different time periods. One explanation of this link is based on monetary policy. The forecasting ability of the term spread on economic growth is based on the fact that interest rates reflect the expectations of investors about the future economic situation when deciding about their plans for consumption and investment. This thesis examined the predictive ability of the term structure of interest rates on economic activity, and the effects of different monetary policy regimes on the predictive ability of the term spread. The South African experience offers a unique opportunity to examine this issue, as the country has experienced numerous monetary policy frameworks since the 1970s. The study employed the Generalised Method Moments technique, since it is considered to be more efficient than Ordinary Least Squares. Results presented in this thesis established that the term structure successfully predicted real economic activity during the entire research period with the exception of the last sub-period (2000-2004) when using the multivariate model. In the periods of financial market liberalisation and interest rates deregulation the term structure was found to be a better predictor of economic activity in South Africa. These findings emphasise the importance of considering the prevailing economic environment in testing the term structure theory.

- Description: The study investigates how rural Grade 4 teachers and learners experience the transition from Oshikwanyama to English as a medium of instruction. The study was conducted at a rural school in Oshana region in northern Namibia. The research site and participants were purposefully selected. Grade 4 teachers and learners were interviewed and observed. Relevant documents were also analyzed. The purpose was to understand participants’ experiences, perceptions and practices in relation to their experience of the transition to English medium instruction. The study revealed out that both Grade 4 teachers and learners are struggling to teach and learn through the medium of English. This was borne out by participants’ responses, classroom practices and document analysis, especially learners’ oral presentation and written work. The conclusion is drawn that limitations in English proficiency overshadow the good intentions of the curriculum. This was evident in the fact that Grade 4 learners at a selected school found it difficult to cope with the demands of the curriculum. In addition, most of the learners have poor literacy skills even in their mother tongue, Oshikwanyama. In the linguistic sense, proficiency in the first language can pave the way for second language to flourish. If the reverse is the case then the learner might find it difficult to acquire linguistic skills in the second language. The study concludes that for the sake of effective learning, an intervention on professional development needs to be in place. This might help rural lower primary teachers to upgrade their existing skills particularly in terms of the English language proficiency as well as how to prepare learners for the transition to English.

The trouble with culture : Plato's critique of poetry

- Description: In this thesis I argue that Plato's critique of poetry, taken in its proper context, is a serious and relevant critique of popular culture. In the first chapter I argue that the poetic reforms proposed in Books 2 and 3 and Book 10 of Republic stand at the front of a total reform of Greek culture. I argue for the consistency of Plato's whole argument and then I claim that if we get Plato's targets right, not fine art or literature, and focus on appropriate modern analogues then we can see why his critique is still important. If we share his claim that we are influenced by popular culture in important and often insidious ways and agree that culture can promote corrupt values, then we have accepted the core of Plato's challenge. If we find his solution distasteful, then the task is to come up with a democratic alternative. In the remaining two chapters I focus specifically on the challenge to the poets, putting the other reforms to the side. In the second chapter I consider a possible reply to the challenge focusing on the worth of the poetry that was expelled. I first look elsewhere in the Platonic oeuvre at the account of beauty in Symposium and Phaedrus but I argue that neither of them gives anything like aesthetic value that could be usefully applied to poetry. Next I look to some modern accounts of aesthetic value. I argue that while they might go some of the distance against Plato's challenge, they face a difficult task because it is not sufficient positing the value, an account is needed of their positive benefit. In the third chapter I turn to a more direct response to the challenge. Arguably Aristotle offers such a response in the Poetics, in terms of the notion of katharsis. I consider two interpretative candidates for katharsis. The first takes the benefit of poetry to be psychological - katharsis is a purgation of otherwise pathological emotions. I argue that this fails because it misunderstands precisely what Plato's concerns about poetry are, and, furthermore, this account could even be compatible with Plato's worries. The second interpretation takes the benefit of poetry to be ethical- katharsis is a type of ethical clarification which is beneficial in training our emotional responses. I claim that the clarification, and education, is worryingly conventionalist, and doesn't take seriously that Plato's target was popular culture and not great, educative literature. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

The use of Landsat ETM imagery as a suitable data capture source for alien acacia species for the WFW programme

- Description: Geographic Information System technology today allows for the rapid analysis of vast amounts of spatial and non-spatial data. The power of a GIS can only be effected with the rapid collection of accurate input data. This is particularly true in the case of the South African National Working for Water (WFW) Programme where large volumes of spatial data on alien vegetation infestations are captured throughout the country. Alien vegetation clearing contracts cannot be generated, for WFW, without this data, so that the accurate capture of such data is crucial to the success of the programme. Mapping Invasive Alien Plant (IAP) data within WFW is a perennial problem (Coetzee, pers com, 2002), because not enough mapping is being done to meet the annual requirements of the programme in the various provinces. This is re-iterated by Richardson, 2004, who states that there is a shortage of accurate data on IAP abundance in South Africa. Therefore there is a need to investigate alternate methods of data capture; such as remote sensing, whilst working within the existing WFW data capture standards. The aim of this research was to investigate the use of Landsat ETM imagery as a data capture source for mapping alien vegetation for the WFW Programme in terms of their approved mapping methods, for both automated and manual classification techniques. The automated and manual classification results were compared to control data captured by differential Global Positioning Systems (DGPS). The research tested the various methods of data capture using Landsat ETM images over a range of study sites of varying complexity: a simple grassland area, a medium complexity grassy fynbos site and a complicated indigenous forest site. An important component of the research was to develop a mapping (classification) Ranking System based upon variables identified by WFW as fundamental in data capture decision making: spatial and positional accuracy, time constraints and cost constraints for three typical alien invaded areas. The mapping Ranking System compared the results of the various mapping methods for each factor for the study sites against each other. This provided an indication of which mapping method is the most efficient or suitable for a particular area.
