- Description: Research suggests numerous views to account for the influence on practice of teachers’ beliefs. One view states that teachers’ lived experiences shape their beliefs about practice. Another view attributes the influence to school experiences. This research sets out to gain insight into teachers’ beliefs on the role of extensive reading in second language learning. A case study of 9 teachers from 3 schools in Grahamstown, South Africa selected purposefully and conveniently was utilised. The teachers were viewed to be knowledgeable on this matter by virtue of their profession while the 3 schools were selected to represent a private school, a former Model C and former Department of Education and Training (DET) school. Data was mainly collected by means of semi-structured interviews, which utilised in-depth open-ended questions to yield teachers’ past experiences. The findings revealed the following: all the teachers appeared to believe that extensive reading was invaluable and enhanced language skills. However, white and black teachers differed in terms of their early experiences of reading. Whereas for white teachers early experiences with literacy were encountered in the home, for black teachers the school was where they had their first exposure to literacy. In addition formal training in the form of an ACE (Advanced Certificate in Education) seemed to have influenced black teachers’ beliefs about the subject at hand, whereas the role of teacher education/ training was not as significant for white teachers.

- Description: This thesis reports the calibration, imaging and analysis of one epoch of VLBI observations of the v (italics) = J (italics) = 1-0 transition of SiO towards VY CMa. Full polarisation information was recorded, allowing high resolution synthesis maps of each of the four Stokes parameters to be produced. A total of 81 maser components were extracted from the total intensity map, each approximately 1 mas in size. The emission spans approximately 100 x 80 mas in right ascension and declination and is concentrated to the east. The maser component positions were fitted to a ring of radius ~ 3.2R₊ (italics), or 7.2 x 1O¹⁴ cm for a stellar distance of 1.5 kpc. If the stellar position is assumed to be the centre of this ring then almost all of the maser components fall within the inner dust shell radius, which is at ~ 5R (italics)ϰ All of the maser components fall between 1.5R (italics)ϰ and 6R (italics)ϰ. A velocity gradient with position angle was observed in the sparsely filled western region of the maser ring. If interpreted as evidence of shell rotation, this gradient implies a rotational velocity of v (italics) rot (subscirpt) sin i (italics) = 18 km.s⁻¹. The fractional circular and linear polarisations of the maser spots were derived from the Stokes parameter maps. The mean fractional circular polarisation of the masers components was ~ 2 percent and the median fractional linear polarisation was ~ 6 percent, with many spots displaying over ~ 30 percent linear polarisation. The mean circular polarisation implies a magnetic field of ~ 4 G in the SiO maser region if the polarisation is due to Zeeman splitting. Two maser components display a rotation of linear polarisation position angle with velocity, possibly implying a connection between the magnetic field and the velocity field variations in the region of these components.

- Description: This thesis critiques hegemonic theory – especially the impact of a hegemonic state on the ability of small states to develop an independent foreign policy. The research uses Lesotho as a case study of a subordinate state in relation to the Republic of South Africa (RSA) as a hegemonic state. It draws on the history of Lesotho’s quest for sovereignty and argues that this sovereignty is constantly eroded to the advantage of its hegemonic neighbour. This constrains Lesotho’s ability to develop an independent foreign policy.

- Description: The nutrient dynamics in two contrasting estuaries and in the adjacent nearshore environment along the south-east coast of South Africa was investigated seasonally. Due to an inter-basin transfer of water from the Gariep Dam to the Great Fish River, the Great Fish estuary is a fresh water dominated, terrestrially driven system with an annual fresh water inflow of 250 – 650 x 10⁶ m³ per year. In contrast, the Kariega estuary is a fresh water deprived, marine dominated system with a fresh water inflow estimated at 2.5 – 35 x 10⁶ m³per year. The reduced fresh water inflow into the estuary is attributed to regular impoundments along the Kariega River. Water samples were collected from surface and subsurface layers along the length of the estuaries as well as from a series of transects occupied in the nearshore environment. Samples were analysed for nitrate, nitrite, ammonium, phosphate and silicate. Temperature and salinity were recorded at each station. A Land-Ocean Interactions in the Coastal Zone (LOICZ) budget was constructed for each estuary to describe the role of ecosystem-level metabolism as either a sink or a source of phosphorus, nitrogen and carbon. Seasonal variation in physico-chemical properties and nutrient concentrations in the Kariega estuary was minimal due to constant low inflow, while in the Great Fish estuary, concentrations varied in response to changes in flow rate. Nutrient concentrations were consistently higher in the Great Fish estuary than in the Kariega estuary, largely reflecting differences in fresh water inflow. During periods of high flow (32.92 m³.s⁻¹in the Great Fish River) dissolved inorganic nitrogen (DIN) concentrations in the Great Fish estuary were an order of magnitude higher than those recorded in the Kariega estuary. Results of the LOICZ budgeting procedures revealed that in spite of the contrasting hydrodynamic features, the estuaries behave in largely the same manner – both predominantly sources of nutrients with heterotrophic processes dominating over autotrophic actions and both were net denitrifyers during all surveys. This was, however, due to different sets of processes operating in the two estuaries, namely low nutrient concentrations resulting in microbial activity in the Kariega estuary, and riverine influx of nutrients and phytoplankton combined with a short residence time of the water in the Great Fish estuary. In the marine nearshore environment, higher nutrient concentrations were recorded adjacent to the Great Fish estuary than offshore of the Kariega estuary. This was due to a surface plume of less saline water leaving the Great Fish estuary, which acted as an ‘outweller’ of nutrients. Offshore of the Kariega estuary, on the other hand, the nutrient concentrations were characteristic of marine waters due to a lack of fresh water outflow from the estuary. Nutrient concentrations in the marine environment adjacent to the Kariega estuary were, at times, higher than those recorded within the estuary. This observation supports previous statements which suggest that the Kariega estuary is not an ‘outweller’ of dissolved nutrients and particulate material, but rather an extension of the marine environment.

- Description: The reaction of various 2-nitrobenzaldehyde derivatives with methyl vinyl ketone (MVK) in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) has afforded the Baylis-Hillman adducts in moderate to good yield. Dissolution of the catalyst in the solvent before the addition of the aldehyde was observed to improve the yield. Reduction of the Baylis-Hillman adducts was effected by catalytic hydrogenation using a 10% palladium-on- carbon catalyst in ethanol to give quinoline and quinoline-N-oxide derivatives and, in some cases, acyclic reduction products. All products were characterised using NMR and, where appropriate, HRMS methods. Selected quinoline-N-oxides were successfully converted to their corresponding quinoline derivatives using phosphorus tribromide (PBr₃) and DMF as solvent. Conjugate addition of the benzylamine and piperidine nucleophiles to the Baylis-Hillman adducts was also investigated but proved problematic, with one of the substrates undergoing a retro-Baylis-Hillman reaction to afford the aldehyde in ca. 40% yield, but seemingly only traces of the required product. Perkin-type coupling of two 2-methylquinolines with benzaldehyde was successfully effected to afford the desired styrylquinoline derivatives confirming the potential of the Baylis-Hillman approach to the construction of the analogues of known HIV-1 integrase inhibitors. Three ¹³C NMR chemical shift prediction programmes, viz., Chem Window, neural network and HOSE (hierarchically ordered spherical description of environment) methods were applied to selected representative compounds prepared in the project. The results from the three programmes correlated reasonably well with the experimental carbon-13 chemical shift data for each of the selected compounds.

- Description: For a long time the rights of disabled persons have been ignored worldwide. A major obstacle faced by disabled persons is discrimination in the workplace. Due to the development of a social approach to disability and the efforts of the Disability Rights Movement, legislation has been passed throughout the world to improve this dire situation. The thesis considers the efficacy of some of these statutes. It is concluded that stigma and negative stereotypes remain a constant hurdle in overcoming discrimination. The forthcoming UN Disability Convention is demonstrative of the recognition of the importance of the needs and rights of disabled people. The convention proposes some innovative measures to overcome stigma and stereotyping. Mental health problems constitute one of the leading causes of disability. The thesis explores how people with mental health problems fit within the concept of people with disabilities and whether they are included in anti-discrimination legislation and affirmative action measures. Special attention is given to statutory definitions of disability, the different forms of discrimination and the concept of reasonable accommodation. A comparative approach is taken to analyse how South Africa's disability law measures up against that of Britain and Australia in terms of its substantive provisions and enforcement thereof. In considering the South African position American and Canadian jurisprudence is consulted in order to aid in interpretation. It is concluded that although South Africa has a comparatively good legislative framework, it is held back by an overly restrictive and medically focused definition of disability. As a result many individuals with mental health difficulties, desirous of obtaining and retaining employment may be excluded from protection against discrimination in the workplace. It is argued that it will be necessary either to amend the Employment Equity Act or for the courts to adhere strictly to the concept of substantive equality in order to ensure that the rights and dignity of people with mental health difficulties are adequately protected.

- Description: The arts in many countries, but particularly in developing ones, are coming under increasing financial pressure and finding it difficult to justify the increases in government funding needed to maintain and grow the cultural sector. The trend in cultural economics, as well as in other areas, appears to be towards including qualitative valuations, as well as the more traditional quantitative ones. This thesis argues that the value of cultural events should include long term historical qualitative analysis, financial or economic impact and a valuation of the positive externalities provided by cultural events and that any one of these should only be regarded as a partial analysis. Four methods of valuing the arts using the South African National Arts Festival (NAF) as an example are demonstrated. Firstly, a qualitative historical analysis of the role of the NAF in South Africa’s transformation process from Apartheid to the democratic New South Africa is examined, using theories of cultural capital as a theoretical basis. It is argued that the value of cultural events needs to take into account long-term influences especially in countries undergoing political and social transformation. The second valuation method applied is the traditional economic impact study. Four economic impact studies conducted on the NAF are discussed and methodologies compared. It is concluded that, despite the skepticism of many cultural economists, the method can provide a useful partial valuation and may also be used for effective lobbying for government support of the arts. Chapter four discusses willingness to pay studies conducted at the NAF in 2000 and 2003 (as well as a pilot study conducted at the Klein Karoo Nationale Kunstefees). It is found that lower income and education groups do benefit from the positive externalities provided by the Festival and that this is reflected in their willingness to pay to support it. It is also argued that such contingent valuation studies can provide a reasonably reliable valuation of Festival externalities, but that they may be partly capturing current or future expected financial gains as well. Finally, the relatively new choice experiment methodology (also called conjoint analysis) is demonstrated on visitors to the NAF. The great advantage of this method in valuing cultural events is that it provides part-worths of various Festival attributes for different demographic groups. This enables organizes to structure the programme in such a way as to attract previously excluded groups and to conduct a cost-benefit analysis for each part of the Festival.

- Description: A novel glucose oxidase from Penicillium canescens (Tt42) was isolated, purified and characterised. The P. canescens Tt42 was cultivated using an optimised growth medium from literature, and maximum glucose oxidase activities of 11.5 U/ml and 6.9 U/ml for the intra- and extracellular fractions were obtained. Maximum glucose oxidase production was achieved after 72 hours at 28°C which coincided with glucose depletion. A total of 1104 U (from 60ml) of glucose oxidase was produced with a biomass specific glucose oxidase activity of 1.08 Umg[superscript -1] Four methods of cell disruption were evaluated for release of intracellular glucose oxidase from P. canescens Tt42 cells. These methods were; sonication, French press, Freeze-Thaw and a high pressure cell disrupter (Z-Plus Series) from Constant systems. All the methods were successful in releasing the intracellular glucose oxidase from P. canescens Tt42. The use of the Constant Systems high pressure cell disrupter was preferred, since it was the simplest and most rapid method. Ammonium sulphate precipitation was shown to be effective as an initial purification step for extracellular glucose oxidase from P. canescens Tt42. Comparison of the intra- and extracellular glucose oxidase fractions using isoelectric focusing showed 2 isoenzymes in both fractions. The pI values of the isoenzymes were determined to be 4.30 and 4.67, with the former being dominant. Since both the intra- and extracellular fractions contained the same isoenzymes of glucose oxidase, further purification studies were performed using the extracellular fraction. The glucose oxidase from P. canescens Tt42 was purified using 3 main techniques: ammonium sulphate precipitation (60% - 70% cut), anion exchange chromatography (Super Q 650M) and size exclusion chromatography (Sephadex S200HR). The glucose oxidase was determined to be ±80% pure by size exclusion chromatography. The final purified glucose oxidase was lyophilised, and an overall purification yield of 10.3% was achieved with an 8.6-fold purification. The purified glucose oxidase was confirmed to be catalase free. Glucose oxidase from P. canescens Tt42 was determined to be a dimeric protein (M[subscript r] ±148kDa) likely consisting of 2 equal subunits (M[subscript r] ± 70kDa). The temperature optimum range was shown to be 25-30°C. The optimum pH for the oxidation of β-D-glucose was pH 7. The enzyme was shown to be stable at 25°C for 10 hours, with a half life of approximately 30 minutes at 37°C. The lyophilised enzyme was stable at -20°C for 6 months. The properties of glucose oxidase from Tt42 were comparable to alternative glucose oxidase enzymes from Aspergillus and other Penicillium species. Glucose oxidase from P. canescens Tt42 was shown to have distinct kinetic characteristics. The V[subscript max] and K[subscript m] were shown to be 651 Umg[superscript -1] and 18.4 mM towards β-D-glucose. The catalytic kcat and specificity k[subscript cat]/K[subscript m] constants for glucose oxidase from P. canescens Tt42 were shown to be 791 s[superscript -1] and 40 s[superscript -1]mM[superscript -1] each respectively. The specificity constant (k[subscript cat]/K[subscript m]) of glucose oxidase from P. canescens Tt42 was determined to be 1.3-fold higher than that that of A. niger (Sigma Type VII) and 8.7-fold lower than that of P. amagasakiense (ATCC 28686) from literature.

- Description: A novel glucose oxidase from Penicillium canescens (Tt42) was isolated, purified and characterised. The P. canescens Tt42 was cultivated using an optimised growth medium from literature, and maximum glucose oxidase activities of 11.5 U/ml and 6.9 U/ml for the intra- and extracellular fractions were obtained. Maximum glucose oxidase production was achieved after 72 hours at 28°C which coincided with glucose depletion. A total of 1104 U (from 60ml) of glucose oxidase was produced with a biomass specific glucose oxidase activity of 1.08 Umg[superscript -1] Four methods of cell disruption were evaluated for release of intracellular glucose oxidase from P. canescens Tt42 cells. These methods were; sonication, French press, Freeze-Thaw and a high pressure cell disrupter (Z-Plus Series) from Constant systems. All the methods were successful in releasing the intracellular glucose oxidase from P. canescens Tt42. The use of the Constant Systems high pressure cell disrupter was preferred, since it was the simplest and most rapid method. Ammonium sulphate precipitation was shown to be effective as an initial purification step for extracellular glucose oxidase from P. canescens Tt42. Comparison of the intra- and extracellular glucose oxidase fractions using isoelectric focusing showed 2 isoenzymes in both fractions. The pI values of the isoenzymes were determined to be 4.30 and 4.67, with the former being dominant.

- Description: This thesis seeks to gain a holistic understanding of consumption issues in the popular music market, such that it needs to account for the influence of 1) technological factors, 2) institutional factors, 3) cultural factors, and 4) an ontological aspect; as these are identified to be the most prominent aspects in the literature on the market. While there is a bourgeoning literature on the market, there has been little formal attempt to link such issues in a comprehensive fashion. The methodology applied provides a critique of the literature on specific consumption theories which have apparent pertinence to the music market. Each of the sociological, psychological, and economic theories (neoclassical and radical) is found to be too generalized to provide such an understanding, in that many issues concerning the music market would need to be eschewed if these theories were to be applied in an orthodox fashion. Moreover, the theories tend to point towards each other for the possibility of a credible, holistic consumption analysis. The most useful and all-encompassing consumption theory reviewed is the systems of provision approach advanced by Fine and Leopold (1993), in that the approach aims to be sensitive to the difference between commodities in terms of the economic and social processes and structures by which they become commodities, and thus it can allow one to consider adequately the four requirements identified above for a holistic understanding of the market. This approach is then applied to the western music market with the aim of 1) testing the approach identified, and 2) making a specific comment of the market. The market is found to be characterized historically by three distinct periods, each with distinct systems of provision (i.e. each with the four factors identified above relating to each other in a certain manner). It is proposed that preference formations in the final period identified have been institutionalized to a large extent, and there is a low probability of change occurring. The systems of provision approach is argued to be beneficial in highlighting which aspects of the existing consumption theories are relevant to the market at a point in time, and to what extent. Thus the richness of the approach stems from its ability to gain a holistic understanding, and to identify theoretical discussion topics, such as those concerning political economy. The approach is then applied to the South African music market, using the same historical methodology, in conjunction with current empirical evidence from the market. Doing this allows one to test the generality of the systems of provision approach, and to attempt to make a comment on the South African market. The techniques for obtaining empirical evidence are argued to be sound, but resource constraints prevented the research from reflecting a holistic view of the market. Nonetheless, a rich perspective is provided from interviews with prominent agents in the market, and thus the chapter is argued to provide the beginning of an understanding of preference formations in the South African music market, in which little research has been conducted (Stella, 2005).

- Description: The use of electronic mail (email) has evolved from sending simple messages to task delegation and management. Most mail clients, however, have not kept up with the evolution and as a result have limited task management features available. On the other hand, while issue tracking systems offer useful task management functionality, they are not as widespread as emails and also have a few drawbacks. This thesis reports on the exploration of the integration of the ubiquitous nature of email with the task management features of issue-tracking systems. We explore this using simple ad-hoc as well as semi-automated tasks. With these two working together, tasks can be delegated from email clients without needing to switch between the two environments. It brings some of the benefits of issue tracking systems closer to our email users.The system is developed using Microsoft VisuaI Studio.NET. with the code written in C#. The eXtreme Programming (XP) methodology was used during the development of the proof-of-concept prototype that demonstrates the integration of the two environments, as we were faced at first with vague requirements bound to change, as we better understood the problem domain through our development. XP allowed us to skip an extended and comprehensive initial design process and incrementally develop the system, making refinements and extensions as we encountered the need for them. This alleviated the need to make upfront decisions that were based on minimal knowledge of what to expect during development. This thesis describes the implementation of the prototype and the decisions made with each step taken towards developing an email-based issue tracking system. With the two environments working together, we can now easily track issues from our email clients without needing to switch to another system. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This thesis develops the first open population model for any shark species worldwide using the Cormack-Jolly-Seber (CJS) model. In conjunction with a tagging study, five auxiliary studies were conducted to investigate stock structure, post-release mortality, tag shedding, and tag-reporting rates. The results from each of the studies were used to correct for any violations of the models assumptions to provide the first unbiased estimates of survival and abundance for the raggedtooth shark (Carcharias taurus) in South Africa. The C. taurus population exhibited complex stock structuring, by size and sex. Competitive shore anglers fished an estimated 37, 820 fishing days.year⁻¹ (95% C.I. = 28, 281 - 47, 359 days.year⁻¹) for sharks, and caught 1764 (95% C.I. = 321 – 3207) C. taurus. Although released alive, post-release mortality ranged from 3.85% for young-of-the-year sharks to 18.46% for adult sharks. Between 1984 and 2004, a total of 3471 C. taurus were tagged. In all, 302-tagged sharks (8.7%) were recaptured. Both juvenile (< 1.8 m TL) and adult sharks (> 1.8 m TL) displayed philopatric behaviour for specific parts of their ranges, including gestating and parturition areas. Significant differences were observed in the percentage of recaptures between the different tag types, tagging programs, individual taggers and capture methods used to tag sharks. The annual tag retention rate for juvenile sharks, 94.19% (95% C.I. = 80.68% - 100.00%) was significantly higher than for adult sharks, estimated at 29.00% (95% C.I. = 6.76% - 64.39%). Tag reporting rates, from fishermen varied both spatially and temporally from 0.28 (95% C.I. = 0.00 – 0.63) to 0.77 (95% C.I. = 0.56 – 0.97). Associated tag wound damage and biofouling growth indicated that B-type tags were a suitable tag type for use on C. taurus, whereas C-type tags were not. The CJS bias-adjusted estimate for juvenile survival was 0.456 (95% C.I. = 0.367 – 0.516) and for adult sharks, 0.865 (95% C.I. = 0.795 – 0.915). From 1984 to 2004 the mean bias-adjusted population size for juvenile sharks was estimated at 3506 (95% C.I. = 2433 – 4350) and for adult sharks, 5899 (95% C.I. = 7216 – 11904). Trends in abundance over the 20-year study period indicated a stable, healthy population.

- Description: The research explored the causal relationship between the communal land tenure and the stagnant agricultural productivity in rural villages. It is assumed that there is covariance between the communal land tenure and the stagnant agricultural productivity. The communal land tenure deprived the villagers of the land ownership rights to mortgage their landholdings to secure agricultural credit from financial institutions, or to advance them as own contributions to obtain Government-provided grants under the ILRAD. Under such circumstances, the villagers could not raise the level of agricultural productivity. The Permit to Occupy (PTO) certificates, issued to the landholders, provided for usufruct rights only i.e. right to occupy and use an allotment. The related research was conducted at Nonkcampa village. The metatheory, “Positivism” and the quantitative paradigm were applied to collate and analyse the data. The research findings confirmed the correlation between the land tenure and the agricultural productivity, as the respondents claimed not to have had any access to agricultural inputs. Hence, the agricultural productivity on the arable land had stagnated.

- Description: At present, there is an emphasis in South African education on promoting multicultural classrooms in schools. This thesis examines the classroom culture of a South African English-medium school, where the majority of the learners are Second Language English learners. It first describes, in the form of a case-study, how two teachers have constructed the culture of their foundation phase classrooms. It then considers why the two teachers have constructed their classrooms in such ways by exploring their knowledge and understanding of, and attitudes towards, multiculturalism, second language acquisition and multilingualism. The study also briefly considers whether teacher training has sufficiently prepared these teachers for the challenges of a multicultural classroom. The data is discussed in terms of education and second language acquisition theory and South African education and language policies. The results of this study indicate that for the most part the classroom culture is distinctly Western and that the teachers have two fundamental assumptions that underpin their action and classroom construction. The first is that a lack of exposure to English is the primary cause of language problems for L2 learners and the second is that the L1 does not need to be maintained or promoted in the school environment because learners are sufficiently exposed to their L1 in the home. The thesis concludes that shortcomings in training and information encourages these two assumptions to take root and that more in-service training that focuses specifically on the nature of second language acquisition and multiculturalism is necessary.

- Description: This paper explores the utility of Weingarten's (2003) witness positions in the understanding of compassion fatigue in people who care for their own family members with AIDS. The research is embedded in Weingarten's theory of witnessing and narrative theory and practice. The literature review explores the shift from hospital-based care to community/home-based care which has led to family members assuming the role of caring for their family members with AIDS, an overview of the effects of caring for AIDS patients on caregivers and an overview of Weingarten's (2003) theory of witnessing with special emphasis on the witnessing positions and their consequences. Interviews, based on narrative theory and practice in which Weingarten's theory is rooted, gave access to the participants' experiences, which were then analysed and interpreted through a framework developed from the witnessing theory. This article demonstrates the utility of Weingarten's (2003) theory of witnessing to people who are caregivers to their own family members with AIDS. I argue that witness positions occupied by caregivers during witnessing determine whether the caregivers will experience compassion fatigue. The negative consequences related to compassion fatigue that will be reviewed could probably be prevented through active, intentional, compassionate witnessing.

- Description: This paper explores the utility of Weingarten's (2003) witness positions in the understanding of compassion fatigue in people who care for their own family members with AIDS. The research is embedded in Weingarten's theory of witnessing and narrative theory and practice.

- Description: This thesis looks at file execution as an attack vector that leads to the execution of unauthorized code. File integrity checking is examined as a means of removing this attack vector, and the design, implementation, and evaluation of a best-of-breed file integrity checker for the Linux operating system is undertaken. We conclude that the resultant file integrity checker does succeed in removing file execution as an attack vector, does so at a computational cost that is negligible, and displays innovative and useful features that are not currently found in any other Linux file integrity checker.

- Description: This research which makes reference to Sappi South Africa is grounded in a South African context, within the forestry industry. The aims of the study are to- 1. Provide a description of corporate social investment (in a Sappi/ South African context) from a theoretical, corporate and legislative perspective which will describe current Sappi CSI activity, its implementation, measurement and the driving force behind them. 2. To articulate a sound understanding without judgement of the current status of corporate social investment based upon the application of (1) above. 3. To position Sappi’s CSI approach on a macro government/ corporate power scale which will facilitate rich understanding concerning the long term sustainability of Sappi’s CSI approach on the corporation, the forestry industry and the South African economy. 4. To distill a consensual interpretation that is more informed and sophisticated than previous constructions within Sappi Forest Products Division. The qualitative research is descriptive. A single case-study method has been adopted. Corporate Social Responsibility (CSR), as a late twentieth-century American movement, is a modern manifestation of an ancient debate amongst philosophers and theologians in many lands and cultures about the morality of commerce itself (Hood, 1996). Friedman (1962) quoted in Anshen (1980:10) argues that business should not and must not deviate from its profit orientation and that it should be concerned only with its economic performance. Friedman supported the notion ‘the business of business is business’ and adds, as quoted in Smith (1990:60), that to suggest corporations should have a social responsibility is to fail to understand the way in which the market is and must be played and asks, ‘if business does have a social responsibility other than making profits for shareholders, how are they to know what it is? Frederick et al, (1998:36) argue that Corporate Social Responsibility balances power with responsibility, responds to public needs and expectations and can contribute to correcting societal imbalances implicit in most economies. Smith (1990:89) suggests that the social control of business is achieved by either virtue of moral obligation, market forces and legislation, or, manipulation, inducement and force. Beesley and Evans (1978) quoted in Smith (1990:54) note ‘there is recognition of the growth of corporate power and the consequent perception of relative shift from government to companies as the source of social improvement and the means to promote specific items of social welfare.’ On this basis it may therefore be concluded that societal responsibilities should be shared between government and business, and in this way power balanced and a healthy pluralistic state developed. The vision of Sappi’s Corporate Social Investment program is to be instrumental in empowering and creating opportunities for both personnel and their dependent communities in order to address their self-defined needs. Sappi’s CSI activity is concentrated on education and community development, environmental preservation and conservation, social welfare and arts and culture. CSI practices are driven by morality, enlightened self-interest and by the South African Government. If the corporation had only started trading in 2005 would the CSI vision be driven by the same ‘gears’, or would the moral obligation and enlightened self-interest become less apparent? It is recommended that the Sappi CSI initiative must embrace CSI and uplift it to the next level by implementing the change management process, outsourcing at least the rural CSI initiative and expanding into a more brand orientated CSI strategy. Sappi also needs to make strategic CSI alliances with other organizations.

- Description: sustained multiple concussions may be at risk of cumulative impairment. The role of neuropsychological testing in the management of sports-related concussion is a contentious and challenging issue which has gained credibility given the lack of clear and well-established guidelines pertaining to the diagnosis, assessment and return-to-play decisions following concussion. Despite various traditional paper and pencil tests being shown to be effective indicators of postconcussive neuropsychological dysfunction, testing has not been widely implemented, due to time- and labour-demands. ImPACT, a computer-based neuropsychological assessment instrument, has been recognised as a valid and reliable tool in the monitoring of athletes' symptoms and neurocognitive functioning preseason and postconcussion. As a part of larger-scale concussion research conducted on top-team university rugby players, this is an in-depth case study conducted on a 20-year old participant with a history of multiple concussions, who was referred following a concussion sustained during the season. The objectives of the study were: (i) to determine the sensitivity of ImPACT versus WAIS-III Digit Span and Trail Making Test during the acute postconcussive phase; and (ii) to examine the sensitivity of ImPACT versus a comprehensive battery of neuropsychological tests to possible residual deficits as a result of the multiple concussions. ImPACT was determined to be more sensitive to acute postconcussive impairment following concussion than Digit Span and Trail Making Test. Furthermore, the ImPACT preseason baseline scores appear to be sensitive to neurocognitive dysfunction, possibly due to cumulative concussive injuries.

A case study of teacher modification strategies in an ESL classroom context

- Description: The purpose of this study is to explore and discuss the use of teacher modification strategies by a high school teacher in the Eastern Cape province of South Africa in an English second language classroom. This teacher does not share the mother tongue of the learners. Unlike other teachers who resort to code switching when teaching L2 learners, this particular educator does not have that liberty. Code switching has been found to be a useful strategy for teaching and learning (Adendorff 1996, Marawu 1996). Code switching will henceforth be abbreviated as CS in the rest of the text. Often teachers use CS to help students understand as an avoidance strategy to teach in English. They have no other way of getting through to students because they haven't been shown the benefits of teacher modification strategies employed by the teacher I have observed in this study. The study therefore seeks to establish or investigate and describe the modification strategies the teacher uses to make his lessons comprehensible to his learners and to accommodate the needs of his L2 learners in view of the fact that he does not share the language of his learners. The motivation behind this study stems from the difficulties experienced by L2/ESL learners learning through the medium of English. These problems are described by researchers such as Macdonald (1990), Eiseman (1992), NEPI report (1992). These difficulties relate to the lack of vocabulary, low proficiency levels and comprehension skills. In view of the above, this case study research was conducted on one teacher to find out or investigate how he modifies his teaching strategies. It has been revealed in the literature studied / reviewed that teachers employ a variety of teaching strategies to adapt to the needs of their L2 learners. (Long (1983), Wong-Filhnore (1985), Chaudron (1988), Huizenga et al (1990)). The teacher in this study has also been found to employ the main strategies to modify his teaching practice. It is clear from the interviews with both the teacher and his students, that this particular teacher makes full use of a range of language and methodological strategies to help his students understand his lessons. It is hoped that the findings of this research may illuminate some valuable insights in the necessity and usefulness of teacher modification strategies for all teacher trainers so that our teaching institutions can provide a variety of methods for teacher trainees to help L2 students develop their English language skills.

- Description: The benefits of informal mentoring are numerous and organisations have recognised these benefits in terms of organisational development. There has been an attempt to harvest these benefits through the introduction of formal mentoring programmes as a tool to fast track and then ultimately retain internal capability. This research on formal mentoring programmes occurred within a qualitative paradigm and data was obtained through document analysis and interviews from five mentoring pairs in one organisation and four mentoring pairs in another. The data was then presented and analysed in terms of the models proposed in the literature. The aim of this research was to evaluate formal mentoring programmes within South African organisations based on a framework provided by the literature. It was found that the literature proposed no formal evaluation model and thus, one was developed based on models of programme evaluation and formal mentoring implementation models. On the evaluation of the two formal mentoring programmes, it was found that there are some issues raised in the literature that are pertinent to both organisations but that there were also issues that were only relevant to one of the programmes. According to the research the differences in perceived success of the mentoring programme lay in the goals of the programme relating to the broader goals and culture of the organisation. It is recommended that future research investigate the impact of organisational culture on the effectiveness of formal mentoring programmes. The research also identified a need for supportive resources although this study did not assess the appropriateness and sufficiency of the resources. Organisations also need to implement effective evaluative practices in order to implement effective changes to the programme.

- Description: On the 21st September 1995, the government introduced the Motor Industry Development Programme (MIDP), in compliance with the General Agreement on Tariffs and Trade (GATT) and the World Trade Organization (WTO). Deliberate efforts by the South African government were required to promote structural changes to the domestic motor industry by opening up the economy to international competition through a programme of tariff reduction and export promotion. The integration of the South African automotive industry into global markets would have been extremely difficult, if not impossible, without the MIDP and it would thus be safe to conclude that the economic performance of the researched would have been close to impossible if it was not for the MIDP. The MIDP, as an economic policy, has been embraced by the researched company as a "vehicle" to drive corporate goals in terms of value creation for all stakeholders. The research proposition that the MIDP as an economic policy has contributed to the economic performance of the researched company is examined. In this respect, Annual and Management Accounting reports were analyzed to determine the effect the MIDP has had on the researched company over the last ten years. In addition, two semi-structured interviews were also conducted with the Strategic Finance Planning executive and the Financial Controller of the company. The results show that the MIDP has had positive spin-offs for the researched company. The same results should be valid for the other original equipment manufacturers (OEMs) in the local automotive industry that have embraced the MIDP as a vehicle to create economic value added.
