- Description: Knowledge Management is associated with organisational initiatives in response to the demands of a knowledge-based economy in which the potential value of knowledge as a source for competitive advantage is recognised. However, the lack of a common understanding about knowledge itself, its characteristics and how it is constructed has led to diverse approaches about how to "manage" it. This study presents a critical overview of traditional and contemporary KM approaches. The main focus of this study was to discover and apply a suitable methodology for assessing an organisation's knowledge processing environment. This includes an analysis of the current practices and behaviours of people within the organisation relating to the creation of new knowledge and integrating such knowledge into day-to-day work. It also includes inferring from the above practices those policies and programmes that affect knowledge outcomes. This research makes extensive use of the Knowledge Life Cycle (KLC) framework and the Policy Synchronisation Method (PSM) developed by advocates of the New Knowledge Management movement. A case study approach was followed using a range of data collection methods, which included personal interviews, a social network survey and focus group discussions. The selected case is the small IT department at the East London campus of Rhodes University. Evidence from the case suggests that the knowledge processing environment within the IT department is unhealthy. The current knowledge processing practices and behaviours are undesirable and not geared towards the creation of new knowledge and the integration of such knowledge within the business processes of the IT department. There is little evidence of individual and organisational learning occurring and the problem solving process itself is severely hampered by dysfunctional knowledge practices. The study concludes that the above state of affairs is a reflection of the quality and appropriateness of policies and programmes in the extended organisation. Equally, the local definition of rules, procedures and the execution thereof at a business unit level is mostly lacking. The study illustrates that a systematic assessment of the knowledge processing environment provides the organisation with a sound baseline from where knowledge-based interventions can be launched.

- Description: Prior to the democratic elections of 1994, South Africa was daunted by legislation flooded with racial segregation. Adoption across racial lines is, because of South Africa’s racially segregated past, a relatively recent phenomenon in this country. The number of legal adoptions has increased dramatically, especially after its legalization in 1991. Parents may adopt across racial lines for an array of different reasons, from not being able to conceive a baby, to wanting to give a child the best opportunity in life. This study explored the experiences of white parents who have adopted black children, paying particular attention to how they deal with issues of “racial” identity. In-depth interviews were used to generate qualitative data pertaining to the parental perceptions of their motivation for, and experiences of adopting a child transracially in South Africa. The study aimed to explore their motivation for adopting and experiences, as well as issues relating to “racial” identity. Recommendations have been made to assist parents who are interested in adopting transracially. The report presents findings relating to the unique characteristics of the participants who have adopted transracially. These include adopters’ motivation and thought processes before taking the relevant steps to adopt transracially; the support that they have received from others in their decision to adopt transracially; communication patterns; their relevant concerns regarding the future of their adopted child; and issues pertaining to race, culture, heritage, prejudices and stereotypes. The findings suggest that parents were pragmatic, without regrets, in their views about adopting across racial lines. The parents’ motivations for adopting across racial lines were very similar to various perspectives, but were all due to the fact that they were unable to have biological children. Parents were aware of the child’s identity and cultural issues, which may be more perceptible in the future. Their perceptions, views and opinions, and the future concerns of their children were not unrealistic. Due to the children’s young age a follow-up study of these children should be considered.

- Description: This thesis attempts to examine the construction of 'professionalism' within the newsroom of the Cape Argus, an English-medium newspaper in post-apartheid South Africa. It is a qualitative study which tries to evaluate how a particular mainstream media discourse of 'professionalism' is enacted and struggled over in the attitudes, behaviour and perceptions of entry-level journalists and news managers at the newspaper. It asks what the process of 'becoming a journalist' requires of entry-level journalists in terms of their previous education and personal qualities - and examines the newsroom strategies employed by news managers when entry-level journalists do not meet these particular requirements. This thesis looks at how the pressures of operating a daily English-language commercial newspaper may shape both the 'professional' expectations of news managers and their ability to positively contribute to entry-level journalists' 'newsroom training'. In attempting to examine the nature of journalistic 'professionalism', this study explores the ideology of knowledge construction within mainstream South African media. Operating from a 'radical democratic' perspective of journalism, which prioritises journalism as a vehicle for diverse social, cultural and political expression, this thesis suggests that South African media education needs to enable journalism students' understanding of the ideological construction of journalistic 'professionalism'.

- Description: A new policy incorporating an operational protocol was developed for the establishment of new fisheries in South Africa. The common octopus, Octopus vulgaris was used as a candidate species for the project. The operational protocol consisted of a three-phased development framework, namely information gathering (Phase 0), an experimental fishery (Phase 1) and the final implementation of a commercial fishery (Phase 2). The present study focussed on phase 0 of this theoretical framework and protocol and was implemented by using a proposed octopus pot fishery in South Africa as a case study. Phase 0 included a desktop study, information gathering in the field, an economic feasibility study and the formulation of a Fishery Management Plan and experimental design for the fishery. Information gaps identified during the desktop study were addressed during field investigations into the population structure and biology of O. vulgaris along the southeast coast. Immature females were found to use the intertidal area to feed and grow before migrating to the subtidal area to mature and spawn. Mean size differed substantially between intertidal and subtidal areas, with larger octopus found subtidally. Age and growth trials using tetracycline as a marker showed that O. vulgaris deposit daily growth lines in their beaks. A genetic study showed that there is most likely only one panmitic population along the coast. The economic feasibility study indicated that a longline pot fishery could be feasible provided a 30% catch in 6600 pots/month is attained. Only existing, debt-free vessels should be used in this fishery. The Fishery Management Plan proposed in this study includes management measures such as effort limitation of licences and gear, size restrictions, vessel monitoring systems, and observer programmes. Based on the population dynamics and biology of O. vulgaris it is suggested that a precautionary approach to developing fisheries for this species in both the inter- and subtidal areas along the South African coast.

- Description: The South African coastline has a high potential for mariculture development, particularly in land-based systems, due to excellent water quality, good infrastructure, and relatively cheap land in certain areas. Development of mariculture however, has been slow primarily due to the absence of a national sector development plan to coordinate contribution to development by government, industry and academia. Recent mariculture development plans however, supported by government commitment to stimulate coastal development, offers new opportunity for the sector's growth. These new sector development plans require a multi-disciplinary intensive information base with a strong regional and national spatial component. Geographic Information System (GIS) is a spatial analytical tool, which is capable of handling such large coastal databases and analysing them. Nevertheless, many mariculture GIS planning applications, often developed in isolation and with limited practical use for decision makers, highlighted the need to develop GIS in relation to the mariculture sector development plan. Hence, the aim of this study was to develop and evaluate a GIS for the national and regional mariculture sector planning process in South Africa, in order to identify potentially suitable areas along the South African coastline for mariculture operations. The GIS development in this study was based on the mariculture planning approach developed by PAP/RAe (1996), which recognizes the variations of scales in mariculture planning. Three case studies, representing the diversity of the South African sector plan, were selected to develop the GIS. They included: a national suitability analysis for all land-based culture systems, a specific national analysis on abalone ranching, and a detailed regional analysis of land-based culture and abalone ranching along the Namaqualand coastline. The GIS was developed separately for each case study based on a strategy consisting of six main phases, including: identification of project requirements, developing analytical framework, selection and location of data sources, organization and manipulation of data, analysing data and verifying and evaluation of the outputs. Biophysical, coastal use, and infrastructure criteria were collected, sorted and analysed to identify development constraints. Based on a set of conditions, and Boolean logic and arithmetic operations, unsuitable areas were identified and eliminated. Main constraints for national land-based development included competition over space along KwaZuluNatal Province coastline and restricted access to the coast along the south region of the Northern Cape Province, Wild Coast along the Eastern Cape Province, and Maputaland along KwaZulu-Natal Province. Ten areas along the country coastline were therefore identified as potentially suitable for land-based mariculture. Furthermore, South African abalone ranching potential was found to be limited mostly along the Western and Northern Cape Province's coastline due to the high risk of Paralytic Shellfish Poison (PSP) occurrences, alternative resource use and activities such as commercial fishery, poaching, and conservation. Hence, a total of nine areas along the Northern Cape, Western Cape, and Eastern Cape coastlines were identified as premier areas for abalone ranching. The regional study along the Namaqualand coastline revealed potential conflict between mining activity and mariculture development due to security issues and restricted access to the coast. Land-based mariculture development was confined to the four main coastal urban areas. The highest potential for land-based mariculture was along Port Nolloth and Kleinsee coastlines, whereas marine-based (i.e. abalone ranching) potential was poor along the north part of the coast due to intense marine mining activities, restricted access to the coast, and low kelp bed density. High potential abalone ranching areas were identified south to Kleinsee, and around Port Nolloth. Potential conflict with marine mining activity was minimal since it was localised and not related to kelp bed locations. It was concluded that GIS is a relevant and compatible tool for South African mariculture sector planning. However, future development of GIS as integrated planning tool in mariculture and coastal planning, requires updated spatial data (e.g. recreational activity), and continued interaction among project planners, mariculture specialists and GIS analysts.

- Description: The interaction between farmers, agricultural scientists and extension workers is sometimes overlooked in agricultural entomology. In an attempt to respond to this reality this study examines some foundation of this interaction in relation to the pest management practices of subsistence and small-scale farmers and also highlights the problems that might arise in the implementation of IPM. Problems involving pests occurrence; language barriers; beliefs, knowledge and perception about insects, and visual literacy are examined. The thesis has a two-fold focus, firstly the study of pests on cabbages of subsistence farmers in Grahamstown and secondly a broader focus on other aspects such as cultural entomology, perception of insects and visual literacy specifically in relation to Xhosa speaking people in the Eastern Cape. The most important crop for emergent farmers in the Eastern Cape are cabbages, which have a variety of pests of which diamondback moths and are the most important. Traditional pest management practices tend to influence the development of IPM programmes adopted by these farmers. Eastern Cape farmers apply periodic cropping systems, which had an effect on the population densities of diamondback moth (DBM), other lepidopteran pests and their parasitoids. Considering the maximum population densities of DBM, which were 0.2 - 2.9 larvae/plant, there were no major pest problems. The availability of parasitoids, even in highly disturbed and patchy environments, showed good potential for biological control. Since some extension officers cannot speak the local farmers’ language, a dictionary of insect names was formulated in their language (isiXhosa) to assist communication. Response-frequency distribution analysis showed that the dictionary is essentially complete. The literal translations of some names show that isiXhosa speakers often relate insects to people, or to their habitat or classify them according to their behaviour. Farmers from eight sites in the Eastern Cape were interviewed regarding their knowledge and perception of insect pests and their control thereof. To some extent, farmers still rely on cultural control and have beliefs about insects that reflected both reality and superstition. There is no difference between the Ciskei and Transkei regions regarding insect-related beliefs. Farmers generally lack an understanding of insect ecology. There is a need for farmers to be taught about insects to assist with the implementation of IPM. Leftover pesticides from commercial farms or detergents are sometimes used to manage the pests. When training illiterate or semi-literate farmers, it is important to understand their media literacy so as to design useful graphic and object training media. Generally farmers showed that they either understand graphic or object media depending on the features of the insects being looked at. These findings are discussed with regard to the potential development of IPM training material for subsistence and small-scale farmers in a community.

- Description: The aim of this study is to find out, against the news genre norms, how representations of particular regions are produced in the structure of newspaper reporting in the foreign news sub-genre. The study focuses on news reports concerning Africa, or African countries, in one Tokyo-based newspaper: The Japan Times/Online. The study is theoretically informed by Cultural Studies – a field of study concerned with the study of ideology and power in discourse – and investigates how Africa and African countries are represented as “other” than developed countries. This is a textual study that focuses on the production moment using Critical Discourse Analysis methods. Critical discourse analysis is interested in the study of ideological forms that have become naturalised over time, so that ideology has become common sense. The first part of the study analyses headlines and reveals evidence of ideological positions adopted by The Japan Times/Online in the representation of, firstly, home or Japanese actors, which is very different to the representation of African actors. The second part of the analysis examines the structures of the texts and the language used therein. The evidence from this analysis shows how Africa is represented as a Third World entity through various crises, including a health epidemic, perceptions of political instability and economic instability, an inadequate business image, as well as market and managerial skills, and wars and conflict. The study concludes with a discussion of the representation of Africa and African countries as a part of the Third World entity. This representation reflects and naturalises social inequality between developed countries and those of the Third World, of which Africa is a part. The representation of Africa as a Third World entity also naturalises the social, health, economic and political conditions said to be characteristic of African countries. It is this process of representation that reveals the power relations between Japan as a First World country and Africa as part of the Third World.

- Description: The aim of this study is to find out, against the news genre norms, how representations of particular regions are produced in the structure of newspaper reporting in the foreign news sub-genre. The study focuses on news reports concerning Africa, or African countries, in one Tokyo-based newspaper: The Japan Times/Online. The study is theoretically informed by Cultural Studies – a field of study concerned with the study of ideology and power in discourse – and investigates how Africa and African countries are represented as “other” than developed countries. This is a textual study that focuses on the production moment using Critical Discourse Analysis methods. Critical discourse analysis is interested in the study of ideological forms that have become naturalised over time, so that ideology has become common sense. The first part of the study analyses headlines and reveals evidence of ideological positions adopted by The Japan Times/Online in the representation of, firstly, home or Japanese actors, which is very different to the representation of African actors. The second part of the analysis examines the structures of the texts and the language used therein. The evidence from this analysis shows how Africa is represented as a Third World entity through various crises, including a health epidemic, perceptions of political instability and economic instability, an inadequate business image, as well as market and managerial skills, and wars and conflict. The study concludes with a discussion of the representation of Africa and African countries as a part of the Third World entity. This representation reflects and naturalises social inequality between developed countries and those of the Third World, of which Africa is a part. The representation of Africa as a Third World entity also naturalises the social, health, economic and political conditions said to be characteristic of African countries. It is this process of representation that reveals the power relations between Japan as a First World country and Africa as part of the Third World.

- Description: [From Introduction]. The study involved student teachers and teacher educators providing me with information concerning their perception and understanding of the BETD broad curriculum and needlework and clothing syllabus. The above mentioned are the people who are involved in teacher education thus I found it relevant to have their opinions and understanding of the documents. The contextual analysis has engaged me in exploring a possible area of research specialisation for the two years during the course of studies with Rhodes University; this will serve as an introduction to the particular research to be done through the course of my studies. The focus of this report includes the following: • A critical analysis of (BETD) needlework and clothing syllabus in relation to the BETD broad curriculum; • A socio-historic and economic analysis of the context for which the syllabus has been designed; • An analysis of the learners for whom the syllabus is designed. In this case students provided their autobiography; • An analysis ofthe learning environment in which the syllabus operates; the physical structure and resources. Together with the critical analysis of the curriculum a small scale survey intending to find out the following information from the student teachers and teacher educators was conducted. • The extent to which the broad curriculum differs from the previous teacher education on issues related to democracy, quality, access, cultural bias, racial discrimination and classes (level of economic status); • How the needlework and clothing syllabus addresses the needs of student teachers; • Whether the needlework and clothing syllabus has enough content; • The challenges facing teacher education and how they can be addressed; • Whether the needlework and clothing syllabus is learner-centred; • Whether the syllabus is gender oriented or biased. This evaluation framework provides a foundation for later investigation

- Description: Endoglucanases play an important function in cellulose hydrolysis and catalyse the initial attack on the polymer by randomly hydrolysing the β-1,4 glucosidic bonds within the amorphous regions of cellulose chains. Cellulolytic bacteria have been isolated and characterised from the sewage sludge and the activation of several hydrolytic enzymes under biosulphidogenic conditions of sewage hydrolysis has been reported. The aims of this study were to: identify, induce production, locate and isolate, characterise (physicochemical and kinetic) and purify endoglucanases from anaerobic biosulphidogenic sludge. The endoglucanase activities were shown to be associated with the pellet particulate matter and exhibited a pH optimum of 6 and temperature optimum of 50 °C. The enzymes were thermally more stable when immobilised to the floc matrix of the sludge than when they were released into the aqueous solution via sonication. For both immobilised and released enzymes, sulphate was slightly inhibitory; activity was reduced to 84 % and 77.5 % of the initial activity at sulphate concentrations between 200 and 1000 mg/l, respectively. Sulphite was stimulatory to the immobilised enzymes between 200 and 1000 mg/l. Sulphide stimulated the activities of the immobilised endoglucanases, but inhibited activities of the soluble enzymes above 200 mg/l. The enzyme fraction did not hydrolyse avicel (a crystalline substrate), indicating the absence of any exocellulase activity. For CMC (carboxymethylcellulose) and HEC (hydroxylethylcellulose) the enzyme had K_m,app_ values of 4 and 5.1 mg/ml respectively and V_max,app_ values of 0.297 and 0.185 μmol/min/ml respectively. Divalent ions (Cu²⁺, Ni²⁺ and Zn²⁺) proved to be inhibitory while Fe²⁺, Mg²⁺ and Ca²⁺ stimulated the enzyme at concentrations between 200 and 1000 mg/l. All the volatile fatty acids studied (acetic acid, butyric acid, propionic acid and valeric acid) inhibited the enzymes, with acetic acid eliciting the highest degree of inhibition. Sonication released ~74.9 % of the total enzyme activities into solution and this was partially purified by PEG 20 000 concentration followed by DEAE-Cellulose ion exchange chromatography, which resulted in an appreciable purity as measured by the purification factor, 25.4 fold.

- Description: My study arose in the context of an intervention programme aimed at the development of a child with autism’s communication and social interaction skills. The approach I take is a social constructionist one in which language is considered to be constructive and constitutive of social and psychological reality. This orientation challenges the assumptions of a western psychiatric approach that emphasizes the impairment and deficits associated with autism. The participants of the study are a 6-year-old boy diagnosed with Pervasive Developmental Disorder (Autistic Spectrum), and his mother, father, sister and a volunteer on the intervention programme. The discourse analytic method of conversation analysis is employed as a means of elucidating the collaborative mechanisms employed by both the child and his co-participants in making sense of one another. The specific aims of the study are to closely examine the communicative behaviour and interactive styles of the child and his coparticipants, their implications for communicative success (co-ordinated interaction) or breakdown (discordant interaction), and the implications for how the child is positioned within the discourse in relation to his co-participants. My constructions of the data suggested that a playful, activity-based interactive style constituted by non-verbal turns, affection and short, simple utterances enhance mutual participation and the accomplishment of co-ordinated interaction. Barney’s co-participants sometimes tend to dominate interaction and frequently employ a strategy of repetitive questioning, which functions to direct and constrain the interaction and results in the child’s withdrawal and discordant interaction. This tendency to withdraw, however, seems to function as a means by which the child is able to actively resist positioning by others, and thus constitutes himself in a position of greater power. Furthermore, his use of the pronoun ‘I’ and collaborative negotiation of the words yours and mine suggest the active co-construction and positioning of himself as a separate person in relation to his co-participants. This research informs intervention efforts and encourages the co-participants to reflect on how interaction is co-constructed between themselves and the child.

- Description: The occurrence of Nosema disease, tracheal mites and the “pseudo-parasitic” behaviour of Cape honeybee workers when placed amongst African honeybees – known as the Cape Bee Problem – were studied over a 18 month period. Three surveys, approximately 6 months apart were done. The aims of this study were to establish the distribution and severity of the diseases and compare the disease with the presence of the Cape Bee Problem. Before this survey commenced European Foul Brood disease, Sacbrood (virus), Nosema, Brood nosema, and Tracheal mite have sporadically been reported in the summer rainfall region of South Africa. In the first survey 1005 colonies in 61 apiaries were surveyed, 803 colonies in 57 apiaries in the second, and 458 colonies in 41 apiaries in the third. Samples for disease and parasite analysis were taken at 4 colonies per apiary. Ten colonies per apiary were inspected for Cape Problem Bees, and samples of workers were collected and dissected at each of these colonies. Even with the addition of apiaries to 'fill-up' lost colonies during the second survey, 63% of all colonies were lost by the third survey. There was only a small difference in colony loss between sedentary and migratory beekeepers of 22% compared to 27%. Nosema was more prevalent amongst commercial beekeepers and increased in migratory operations during the survey period. The percentage of colonies infected increased during the survey period from 23% to 32% to 34%. The placement of colonies in Eucalyptus plantations may boost infection. Trachea mites seem to have spread quite rapidly in South Africa since its discovery. This parasitic mite was present in all regions, although in low numbers in three most northern regions. Sedentary colonies had higher levels of infestation than migratory colonies. The number of colonies infested diminished over the survey period, which may be a result of general colony loss. The Cape Problem Bee was less of a problem than anticipated. Colonies succumbed to Cape Problem Bees in all regions. When beekeepers reported high levels of infestation in their bee stocks the colonies would be dead within six months. In apiaries with low infestation the die-out was slower.

- Description: The main question of this thesis is to what extent the rights-based and market-driven nature of the restitution program has given rise to a legalistic and bureaucratic process that negates both the demand-driven and the developmental aspects of restitution as land reform. I answer this question by showing that the choice of a Constitutional model with a Bill of Rights provides the background for a rights-based land reform program. This is especially true for the restitution sub-program, one of the three branches along with redistribution and tenure of the overall land reform program. I then consider the debate around the property clause, and how its inclusion provided the context for a market and rights-based approach to land reform as opposed to a supply-led administrative approach. Because the property clause as a First Generation right prevents expropriation of land without market-related compensation, a complex and legalistic land reform program falling within the ambit of Second Generation rights was formulated to address the gross imbalance in land ownership in South Africa. I argue that the contemporary origin of Second Generation human rights lies within the context of class and anti-globalisation struggles for democracy, and that they are something to be fought for and defended. I discuss the distinction between First, Second and Third Generation rights and identify four spheres within which the struggle for Second and Third Generation rights takes place within modern democratic states. These are the state, the representative public sphere, civil society and the private sphere. I then deal with the problem of trying to turn "paper rights" into realisable rights for the more disadvantaged sectors of society. I also look at what impedes their realisation. I argue that a number of strategies are necessary to ensure the delivery of Second and Third Generation rights. These are an adequate legislative framework, a good communication strategy, the development of institutional capacity to deliver, and if all else fails, access to conflict resolution mechanisms. I consider the major impediments to the realisation of Second and Third Generation rights to be the way in which they are defined in relation to First Generation rights, especially the property clause, the way in which access to rights-backed resources through formal institutions are mediated by the operation of informal institutions, and the dearth of administrative competence in South Africa. My point is that in order for Second and Third Generation rights to have practical benefit for the dispossessed and poor, extraordinary measures are needed. The Restitution arm of the land reform program provides in theory just such extraordinary measures, albeit for only a section of the population. I analyse the effectiveness of the Land Claims Court in assisting restitution claimants and the rural poor to realize their rights. I trace the slow and haphazard shift from a positivistic statutory interpretation (narrow, literal, legalistic) to a purposive interpretation (informed by the Constitutional spirit and social purpose of the legislation) by the Court. This is followed by an analysis of the restitution business process, which means tracing the path of the claim from lodgement to settlement. I set out the costly, complex and legalistic implementation and policy process in some detail. My argument is that in order for a rights-based approach to overcome the impediments outlined in Chapter 3, as well as the property clause in the Constitution, its architects designed a complex process that in the end proved counter-productive in terms of its original aims. The failure of the process to deliver led in 1998 the then Minister of Land Affairs, Derek Hannekom, to appoint a Ministerial Review to investigate the problems. Problems included: slowness of delivery, the crisis of unplannability, low levels of trust between implementers, and high levels of frustration. Two issues are analysed more fully, the rights-driven approach as opposed to the rights-based approach and the lack of claimant participation in taking control of the restitution process. I examine the relationship of the Restitution Commission to the Department of Land Affairs and to municipal land use planning processes. The emphasis on rights within the restitution program had the effect of distancing restitution, especially in the first few years of the programs' existence, from the rest of the land reform program, as well as from the local government process of formulating land development objectives (LDOs), and the Integrated Development Planning (lOP) process. I look at the Port Elizabeth Land and Community Restoration Association (Pelcra) as a case study as it embodies an approach that tries to move beyond a mere reclaiming of rights in land and attempts to implement a developmental approach. I conclude that the rights-based restitution program in spite of its many shortcomings has had some success. It has moved slowly from an overly legalistic judicial program to a more administrative but still bureaucratic process, that has delivered only 27 percent of its product as land reform, the rest going to monetary compensation mainly in urban areas. Thus it can be argued that restitution has been more successful as a program to promote reconciliation along the lines of the Truth and Reconciliation Commission, than as a land reform program, especially if one regards land reform as the restoration of rural land to the indigenous population. There have also been some successful attempts by the Commission, such as in the case of PELCRA, to integrate the processing of its claims with local government planning processes, but progress in this direction remains patchy.

I look at the Port Elizabeth Land and Community Restoration Association (Pelcra) as a case study as it embodies an approach that tries to move beyond a mere reclaiming of rights in land and attempts to implement a developmental approach. I conclude that the rights-based restitution program in spite of its many shortcomings has had some success. It has moved slowly from an overly legalistic judicial program to a more administrative but still bureaucratic process, that has delivered only 27 percent of its product as land reform, the rest going to monetary compensation mainly in urban areas. Thus it can be argued that restitution has been more successful as a program to promote reconciliation along the lines of the Truth and Reconciliation Commission, than as a land reform program, especially if one regards land reform as the restoration of rural land to the indigenous population. There have also been some successful attempts by the Commission, such as in the case of PELCRA, to integrate the processing of its claims with local government planning processes, but progress in this direction remains patchy.

- Description: The development of conservation and management programs for an animal population relies on a knowledge of the number of individuals in an area. In order to achieve reliable estimates, precise and accurate techniques for estimating population densities are needed. This study compared the use of direct and indirect methods of estimating kudu (Trage/aphus strepsiceras), bush buck (Trage/aphus scriptus), common duiker (Sy/vicapra grimmia), and blue duiker (Philantamba manticala) densities on Shamwari Game Reserve in the Eastern Cape Province, South Africa. These species prefer habitats of dense forest and bush for concealment and are therefore not easily counted in open areas. Herein direct observation counts were compared to indirect sampling via pellet group counts (clearance plots, line transects, variable-width transects, and strip transects). Clearance plots were examined every 2 weeks, while all other methods were conducted seasonally, from August 2002 until August 2003. The strip transect method provided the lowest density estimates (animals per hal ranging from 0.001 for bushbuck to 0.025 for common duiker, while direct observations yielded the highest estimates, ranging from 0.804 for bush buck to 4.692 for kudu. Also, a validation of methods was performed against a known population of kudu during which the DISTANCE method yielded the most accurate results, with an estimated density of 0.261 that was within the actual density of 0.246 to 0.282. In addition, the DISTANCE method was compared to helicopter counts ofkudu and its estimates were found to be approximately 2.6 times greater than the helicopter count results. When the assessment of the methods was made, the cost, manpower and effort requirements, coefficient of variation, and performance against a known population for each method were taken into consideration. Overall, the DISTANCE method performed the best with low cost, minimal manpower and effort requirements, and low coefficient of variation. On Shamwari Game Reserve, the DISTANCE method estimated 0.300 kudu, 0.108 bushbuck, 0.387 common duiker, and 0.028 blue duiker per ha, which, when extrapolated to the total number of animals present within subtropical thicket habitat, estimated 1973 kudu, 710 bush buck, 2545 common duiker, and 184 blue duiker.

- Description: This thesis reports on a critical, ethnographic investigation into the reading practices of a group of 14 foundation year students at Rhodes University in 2002. The university had identified all the student-participants as 'underprepared' for university learning: they were from poor, socio-economic backgrounds, used English as an additional language, and had been educated in township or rural schools. Using the Socio-cultural model of literacy (Heath, 1984; Gee, 1990 & Street, 1993), the study explores the culturally-shaped attitudes and assumptions about reading that the students brought with them into a tertiary learning context from their homes, communities and schools. It reports on their subsequent efforts to become academic readers in the disciplinary context of History. Framing Theory (Reid and MacLachlan, 1994) was employed to analyse the kinds of matches and mismatches that arose between the students' frames about the nature and purpose of reading, and those implicitly accepted as normative by teachers in the History department. It accounts for the students' difficulties in achieving epistemological access in terms of a conflict of frames: both the students and their teachers usually failed to recognise each others' constructions about the nature and purpose of 'reading for a degree'. The study'S critical purpose required that its potential for generating emancipatory consequences needed to be investigated. Thus the study reports on how both sets of participants began to reframe their understanding of academic reading, by describing the ways in which they reflected on the findings in the final stages of the research process. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

A case study of the strategic nature of DaimlerChrysler South Africa's corporate social investment programmes in the local communities of the Border-Kei region in the Eastern Cape Province

- Description: Corporate social responsibility has become the business issue of the 21st century. Heightened expectations of the business sector, globalisation and increased media attention on the role of business in society are casting an intense spotlight on this issue. As a result, pressure has built on business to play a larger role in bringing about socio-economic development to many local communities where they operate. While for a long time companies have been involved in the community on a philanthropy basis, many companies today are reassessing the manner in which they conduct their corporate social responsibility programmes. Many companies are including corporate social responsibility issues into their strategic planning process and overall corporate strategy. Emphasis is given to certain strategic indicators that must be present in order for a company to be said to have taken a strategic approach to corporate social responsibility. This study adopted a critical-realist approach using a case study method to evaluate DaimlerChrysler South Africa’s corporate social investment programmes in the local community of the Border-Kei region against these strategic indicators. This new form of engagement is even challenging for a multinational corporation, which may feel that it is only obliged to assist the local community where its corporate headquarters is located. But as companies derive an everlarger share of revenue and profits from international operations, multinational companies are being called upon to redefine “community”, by looking beyond local, domestic and geographical communities to include those in regions where they have factories or factories operated by key suppliers. This study found that DCSA was strategically involved and had a good relationship with its local community. However, the company needs to be more connected with the rural communities to make local projects more successful especially after handover.

The role of management and leadership in the schooling of at-risk learners: a case study of a school in Namibia

- Description: Most schools that serve learners who come from disadvantaged areas and backgrounds face unusually difficult challenges. These schools experience poor performance and disciplinary problems, and teachers lack motivation and commitment. This study explores the role of leadership and management in the schooling of at-risk learners at Pandu Primary School. This school accommodates learners mostly from Hafo, a township characterised by poverty with a high crime rate. However, in spite of these factors school inspectors and advisory teachers perceive the school to be successful. The school uses an abundance of energy and unusually high levels of human effort in a very focused way to improve the teaching and learning standard. The study found the co-existence of apparently conflicting management and leadership approaches in managing and leading the school. Strict control used in the school to make teachers work hard is an element of classical organisational theory, with its emphasis on span of control or number of workers supervised. Policies with strict rules are in place to create a calm atmosphere and serve as directives for teachers and learners. On the other hand, constructivist approaches – such as instructional leadership, transformational leadership, collegial model of management and open systems – are also clearly evident in the findings. Instructional leadership is evident in the emphasis on improvement of classroom practice. Elements of transformational leadership are seen in that the principal motivates the teachers and serves as a role model. The school also has some features of the collegial model of management, and can be described as an open system. Thus, by drawing on management and leadership approaches informed by different traditions and philosophies, the school succeeds against severe odds.

The doctrine of duress in the law of contract and unjustified enrichment in South Africa

- Description: This thesis analyses the doctrine of duress and its application in the law of contract and unjustified enrichment in South Africa. Following an initial examination of the historical development of the doctrine from its roots in Roman and Roman-Dutch law, the study focuses on the current legal position in the two areas of law under review, identifies the substantive and formal deficiencies in the current approach, and suggests, using comparative authorities, how the law might be developed. As far as the law of contract is concerned, after exposing the difficulties inherent in the current approach, and placing the doctrine in its proper context in the South African law of contract generally, it is argued that the duress doctrine finds its juridical basis in the principle of good faith. A more modern and coherent test for duress is then proposed: one that concentrates on the question whether an illegitimate threat was made, which induced a contract in that it left the other person no reasonable choice but to succumb to the proposal. Additionally, the need for South African contract law to recognise and deal with cases of economic duress is emphasised. The study then shifts to an examination of the position in situations where non-contractual performances have occurred under duress: cases that are decided in terms of the principles of the law of unjustified enrichment. The current position is reviewed, and it is shown that the approach to duress cases is substantially different to the approach that applies in contract. An attempt is made to reconcile this problem. From a structural perspective, the nature and application of the relevant enrichment action where a non-contractual performance is made under duress (the condictio indebiti) is also investigated, in the light of approaches to enrichment adopted in both Germany and England, in an attempt to make better sense of this enrichment action in the South African context. The study closes with an analysis of the various contractual, delictual and enrichment remedies that are available once a case of duress has been proved.
