- Description: Terracettes and turf-banked terraces exist at Tiffindell Ski Resort in the Drakensberg of the Province of the Eastern Cape at altitudes between 2750 m and 2880 m on slopes of between 15°and 26°. Ice lenses and interstitial ice exist within turf-banked terraces in winter. During post-winter thaws, soil moisture reaches saturation in at least the upper part of the regolith in which turf-banked terraces occur. These terraces move downslope under the influence of gelifluction (which is essentially a combination of frost creep and solifluction). Terracettes appear to move as a result of frost creep, processes associated with needle ice, and slope wash. Both turf-banked terraces and terracettes are part of the periglacial environment and are active under present climatic conditions at Tiffindell.

- Description: Clark and Wells (1995) constructed a comprehensive cognitive model of social phobic behaviour, in terms of which social phobic behaviour is activated and maintained by a system consisting of negative thoughts and beliefs, anxiety s)mptoms, avoidance and safety behaviours, and processing of self as a social object. The interaction of these elements creates a series of vicious circles which escalate and which keep the phobic individual in a state of chronic -disability, either because they chronically avoid significant social situations or because they find themselves incapacitated by anxiety when they enter them. The Clark and Wells (1995) treatment programme is designed to alleviate the social phobia by targeting the components that form the vicious maintenance cycle and replacing these by new patterns of cognition and behaviour. This treatment programme was designed for individual treatment, and the present study adapted it to a group format. Seven social phobic university students participated in the adapted group treatment format over the course of 13, 2-hour group sessions. Regular assessment of participants' response to the programme was carried out weekly and at two follow-up assessments, with the use of a series of questionnaires. In addition, sessions were audio taped and videotaped, facilitators took notes during sessions and keep records made by participants of their homework exercises. Individual case studies were written for all participants (including two non-completers) in which case narratives were juxtaposed against their responses to each of the self-report questionnaires. These we used as a basis for evaluating the validity of the Clark and Wells theoretical model and in examining the effectiveness of the treatment programme in bringing to awareness and interrupting the cycles that maintained the phobic behaviour. It is concluded that the group programme showed evidence of being very effective and, a group treatment manual was constructed so that it can be employed clinically and in future research.

The biology and molecular ecology of floating sulphur biofilms

- Description: Floating sulphur biofilms have been observed to occur on sulphate-containing natural systems and waste stabilization ponds. It has been postulated that these biofilms form on the surface of the water because sulphate reducing bacteria present in the bottom layers of the water body reduce sulphate to sulphide which then diffuses upwards and is oxidized under the correct redox conditions to sulphur by sulphide oxidizing bacteria. Very little information exists on these complex floating systems and in order to study them further, model systems were designed. The Baffle Reactor was successfully used to cultivate floating sulphur biofilms. Conditions within the reactor could be closely scrutinized in the laboratory and it was found that sulphate levels decreased, sulphide levels increased and that sulphur was produced over a period of 2 weeks. The success of this system led to it being scaled-up and currently a method to harvest sulphur from the biofilm is under development. It is thought that biofilms are highly complex, heterogeneous structures with different bacteria distributed in different layers. Preliminary work suggested that bacteria were differentially distributed along nutrient and oxygen gradients within the biofilm. Biofilms are very thin structures and therefore difficult to study and Gradient systems were developed in an attempt to spatially separate the biofilm species into functional layers. Gradient Tubes were designed; these provided a gradient of high-sulphide, low oxygen conditions to high-oxygen, low-sulphide conditions. Bacteria were observed to grow in different layers of these systems. The Gradient Tubes could be sectioned and the chemical characteristics of each section as well as the species present could be determined. Silicon Tubular Bioreactors were also developed and these were very efficient at producing large amounts of sulphur under strictly controlled redox conditions. Microscopy and molecular methods including the amplification of a section of Ribosomal Ribonucleic acid by Polymerase Chain Reaction were used in an attempt to characterize the populations present in these biofilm systems. Denaturing Gradient Gel Electrophoresis was used to create band profiles of the populations; individual bands were excised from the gels and sequenced. Identified species included Ectothiorhodospira sp., Dethiosulfovibrio russensis, Pseudomonas geniculata, Thiobacillus baregensis and Halothiobacillus kellyi.

- Description: The potential of using mushroom polyphenol oxidase (EC 1.14.18.1) as a biocatalyst for the biotransformation of phenols to produce catechols in an aqueous medium was investigated. Polyphenol oxidase is characterised by two distinct reactions i.e., the ortho-hydroxylation of phenols to catechols (cresolase activity) and the subsequent oxidation of catechols to orthoquinones (catecholase activity). In order to facilitate the development of a process to produce catechols, the accumulation of catechol as a true intermediate product released in the reaction system needed to be investigated, as its release had been disputed due to the oxidation of catechols to o-quinones. Using LC-MS, catechol products were successfully identified as true intermediate products formed during biocatalytic reactions in water.

- Description: The false codling moth (FCM), Cryptophlehia Leucatreta, causes widespread damage to economically important fruit crops throughout sub-Saharan Africa. Fruit are rendered unfit for consumption once they have been stung by FCM larvae. Larval infestation of fruit can lead to significant pre-harvest losses or post-harvest waste, posing a major problem to the citrus industry. Current control of the pest includes the use of chemical pesticides. The larval form of FCM is known to be infected by a granulovirus called Cryptophlebia leucotreta granulovirus (CIGV). Granuloviruses are highly specific against their hosts and are harmless to vertebrates, plants and the environment. The development of CIGV into a biological control agent would offer an attractive and safer alternative for the control of this pest. A full characterisation of CIGV is required prior to the virus being disseminated into the environment. In this project, the characteristics of CIGV will be examined. Viral DNA was extracted from infected larvae and the DNA analysed by restriction fragment length polymorphism (RFLP). Fragmentation profiles of the South African and Cape Verde (CV3) isolates of the virus were compared, revealing distinct differences between them. The size of the CIGV-SA genome was calculated to be 112 kbp, identical to the size of the CV3 isolate. Physical maps for five restriction enzymes were constructed for the CIGV-SA genome. The alignment of these maps with maps the CV3 isolate (for the same enzymes) further highlighted the differences between the isolates. The genetic engineering of granuloviruses could significantly improve the speed of kill of these viruses. Therefore essential genes like egt and granulin were isolated (by PCR) and their position located in the genome. Both genes were sequenced and their phylogeny with other granulin and egt genes investigated. Finally, tbe incidence of CIGV in natural populations of FCM larvae was investigated, by screening field-collected larvae for the presence of the virus. CIGV was successfully detected from dot blots of larval DNA using both radiolabelled and non-radiolabelled probes and by PCR. Trends regarding the incidence of CIGV in natural populations of larvae were also determined.

- Description: The Eastern Cape Region, once had sufficient job seekers with automotive component manufacturing skills and experience. Indications are that this pool has been desiccated. The draining of skills out of the area is starting to affect growth potential and competitiveness in the industry in the area. In 1998, the Skills Development Act was passed to implement the National Skills Development Plan, and to encourage employers to train personnel. The strategy promotes a three faceted approach to encourage the development of skills; Workplace Skills Development Plans, Learnerships and Sector Specific Initiatives. This study will focus on the implementation of learnerships in the Catalytic Converter Canning Industry. The aim of this research is to verify the skills shortages; identify which skills are required by the Catalytic Converter Canning Industry in the Eastern Cape and propose a strategy of addressing these needs by means of learnerships. By studying the Legislation supporting the National Skills Development Plan, conducting a literature study, and interviewing knowledgeable people in the industry, the skills requirements of the industry were identified. Thereafter, a questionnaire was drawn up and completed together with representatives from Eberspächer South Africa, Faurecia Exhaust Systems South Africa, Precision Exhaust Systems and Tenneco Automotive South Africa, the active manufacturers of catalytic converters, for OEM’s worldwide, who are based in the Eastern Cape Region. The empirical study confirmed the findings of the research and skills deficiencies were identified. In conclusion, a strategy is proposed whereby the Catalytic Converter Canning Industry could address the skills shortage by the implementation and development of learnerships.

- Description: This study researched a project to set up a national television service for Botswana to find out whether the service could be used for rural development generally, and in particular to assist the Ministry of Health to implement its health projects in the rural areas and including the fight against the AIDS disease. It reviews conceptions of development and also analyses various communication models that usefully inform the conceptualisation of a TV service that can contribute to development. The study was done by going through reports of feasibility studies on the project and through letters of official correspondence among officials of the Government of Botswana who debated the subject of whether or not the country should have a national TV service. The reports and correspondence were supplemented with interviews of key people involved in the implementation of the project, as well as interviews of officials of the Ministry of Health. The findings of the study are that the Botswana television service project started and ended on a footing that forgot about television, a medium that is dependent on professional and organisational capacity and purpose, and as a result the project did not take-off. A qualitative method was used as the study required in-depth interviews during which new issues kept on emerging and nothing could be pre-determined because the study took place as the project was being implemented. The study was completed in June 2000, at a point where the project should have been completed but it was discovered that the station could not go on air as a television service had not been conceptualised and there was no management structure in place and the Government of Botswana appealed to the British Government for the staff of the British Broadcasting Corporation to come quickly to Botswana to rescue the project and put it on track, supposedly. The study has concluded that the Botswana television service project became stillborn because there was a lack of professional and intellectual capacity to conceptualise the service, and instead there had been too much concentration on the construction of the TV building and acquisition of equipment.

- Description: This study researched a project to set up a national television service for Botswana to find out whether the service could be used for rural development generally, and in particular to assist the Ministry of Health to implement its health projects in the rural areas and including the fight against the AIDS disease. It reviews conceptions of development and also analyses various communication models that usefully inform the conceptualisation of a TV service that can contribute to development. The study was done by going through reports of feasibility studies on the project and through letters of official correspondence among officials of the Government of Botswana who debated the subject of whether or not the country should have a national TV service. The reports and correspondence were supplemented with interviews of key people involved in the implementation of the project, as well as interviews of officials of the Ministry of Health. The findings of the study are that the Botswana television service project started and ended on a footing that forgot about television, a medium that is dependent on professional and organisational capacity and purpose, and as a result the project did not take-off. A qualitative method was used as the study required in-depth interviews during which new issues kept on emerging and nothing could be pre-determined because the study took place as the project was being implemented.

- Description: Most South African manufacturing companies provide some sort of training for its shop floor employees to help them improve productivity and reduce wastage. Unfortunately, training presented on-the-job to operators is more often than not implemented in an unstructured and unplanned manner, usually when a crisis occurs and fires need to be put out quickly. The introduction of the National Qualifications Framework (NQF) demands that training practitioners structure their training efforts and ensure that all training leads to national qualifications. This study is aimed at making a contribution towards the NQF and in particular, the development of shop floor employees. Firstly, a model for operator training was developed from a survey of the relevant literature. This phase of the study identified the components of the model and their respective guidelines. Secondly, the model was e.mailed to managers working in confectionery companies requesting their opinion on the guidelines of the model. Lastly, the feedback received from the empirical study was evaluated, conclusions were drawn and recommendations made, based on the information obtained from both the literature study and empirical study. The results from the empirical study indicated strong concurrence with the theoretical model on operator training. In contrast to theory that the use of rewards after training results in improved productivity, the majority of respondents disagreed with the implementation of a reward What are the long term benefits to an organization with a productivity reward system in place? · What kind of reward system would work best in the confectionery industry? · How would management implement an effective performancerelated reward system at shop floor level?

- Description: The world population is ageing, and this is also relevant to South Africa. At the same time the potential support ratio (the number of persons aged 15 to 64 years per one older person aged 65 years or older) is falling, and the dependency burden on potential workers increases. To alleviate the financial burden on the aged, and their families, it has become necessary to develop a financial plan to cover the cost of frail care. The overall purpose of this research is to determine whether any financial plans exist which are relevant. If nothing existed, a plan had to be developed. The research methodology for this study comprised the following steps: Firstly, the demographics of the world and South Africa were researched. The concept of frail (long-term) care in the United States of America and New Zealand was investigated to determine what is available. The subsidisation concept of the South African Government towards caring for the elderly was also investigated. Secondly, a questionnaire was sent to the residents of five retirement complexes in George to determine their interest in such a plan. The records of the frail care unit that these residents utilise were analysed to determine the number of residents needing frail care. A comparative study of the cost of frail care in the Southern Cape was undertaken. Thirdly, two options to partly subsidise the cost of frail care were examined, where the first option covers the running cost, and the second option, subsidising one third of the frail care cost, builds up a sustainable fund after the first five year period. The funds of the second option can then be utilised in the subsequent years to increase the subsidisation portion of frail care cost. The final step of this study entailed the formulation of recommendations to implement the frail care nursing levy as soon as possible, with special attention given to the following: a) It must be compulsory for new residents to join the fund. b) A yearly capital amount of R100 000 or more is needed to sustain the fund. c) A contract must be drafted to set out all the rules and regulations to the residents. d) An attitude change amongst some residents is required. Individuals must realise that the success of this plan depends upon themselves and with the necessary support could make a significant contribution towards their own peace of mind if and when frail care is needed.

- Description: The research problem addressed in this study was to develop a comprehensive marketing plan that would help an emergency medical service (EMS) in the Nelson Mandela Metropolitan Municipality (NMMM), capture a significant market share and gain a competitive advantage over competitors. To achieve this object, a literature study to determine the key components of a marketing plan was undertaken and used as a theoretical model in developing an actual marketing plan. In addition to the literature study, an empirical study was conducted to identify the key issues critical to the development of a marketing plan for the EMS. The survey method used, based on the key components gained from the literature study, consisted of an in-depth scan of the macro-environment and thorough market investigation of the target industry. The investigation involved the general management and senior personnel from the local emergency medical industry, medical aid schemes and private hospitals and clinics delimited in the study. The results of the above literature study were finally combined with the results of the empirical study and a marketing plan for an emergency medical service was developed. This study concludes with recommendations applicable for the implementation of the actual marketing plan.

- Description: The focus of this study is on assessment in an Outcomes Based Education environment. The question arises as to how assessment of Entrepreneurship and Business Management-N4 can be changed to suit an Outcomes Based Education approach. Action research was used as the research methodology and the findings were reported as case studies. A sample of three colleges in the Eastern Cape was chosen to take part in the study. Only two modules of the Entrepreneurship and Business Management-N4 syllabus were adapted to suit an Outcomes Based Education approach, as the students still had to write the normal external examination at the end of the semester as required by the Department of Education. In the first two cycles the participants implemented Outcomes Based Education in the classroom using only the resources available at the college for the old education system. During the third cycle the researcher implemented Outcomes Based Education in the classroom under the same circumstances, but with the advantage that the researcher benefited from the reflections of the first two cycles. In order for assessment to meet the requirements of an Outcomes Based Education approach, it was necessary to change teaching practices as well. Important aspects such as group work, new assessment methods, the role of resource materials and the training of lecturers were included in the study. At the end of the third cycle a model for the assessment of Entrepreneurship and Business Management-N4 was developed. Recommendations on aspects such as students, lecturers, resources and assessment were made.

- Description: This paper aims at developing a model on which to base good quality franchise relationships. The franchise sector has the potential to generate wealth for the franchisee and the franchisor, create employment and be a tool of empowerment. It is also associated with relatively less risk than other forms of self-employment. However, there have been a disturbing number of failures in the sector and reported cases of abuses of franchisees by franchisors. Some franchisors have sought liquidation of franchise units in courts of law. An investigation was commissioned into the sector with the objective of uncovering problems in the quality of the relationships in the sector. The obligations of both the franchisees and franchisors were stipulated. Aspects of quality were then considered to lay a foundation upon which improvements in the relationships could be based. This was followed by a survey to find the performance gap between the quality of service that was expected from the franchisor and what the franchisees were actually receiving. Five dimensions of service quality – tangibles, reliability, responsiveness, assurance and empathy were empirically investigated. The findings of this research revealed that the quality of service of franchisors fell short in all dimensions. It is arguable that other aspects of quality are being neglected by the franchisors. It is against this backdrop that a model is proposed to improve the quality of service in the franchise relationships. The model incorporates contemporary ideas on quality. Principles of total quality management, quality function deployment, customer satisfaction and self-assessment are applied to the franchise relationship. The use of the model will contribute towards better relationships in the franchise sector.

- Description: With global competition becoming a key concept in the majority of companies worldwide, it is necessary for organisations to develop operations strategies that enable them to meet their customers‘ needs. Organisations will never be capable of reaching future goals without their customers. For this reason it is imperative for organisations to identify what competitive factors are required by the market, and which performance objectives are needed in order to increase the competitiveness of the organisation. In this research, Chapters 1 and 2 were used to identify the main and subproblems of the research, to delimit the research and to provide literature background to operations strategies and related operations topics. The empirical study in Chapter 3 was used to gather information pertaining to the specific requirements of ESA’s customers, and the operations performanceof ESA. Chapter 4 was used to analyse the data gathered from the empirical study. From this analysis it was possible for the researcher to identify the specific requirements of ESA’s customers and the operations performance of ESA. Chapter 5 was used to provide recommendations to bridge the performance gap between the customer requirements and the operations performance of ESA. By effectively implementing all of the recommendations suggested in this research, ESA will be able to improve its operation performance and meet the specific requirements of its market and its customers.

- Description: Education is a powerful and pervasive agent of change. Therefore, it is the key to unlock the doors to development and modernisation. Currently, business and communities knowledge very little about what the FET/Technical College is offering and its importance to the society as whole. Therefore there is a great need to market the technical sector so that the community is knowledgeable about the FET/Technical Colleges. The research conducted focuses on which promotional strategies are effective in marketing the FET Colleges. In order to make technical college students marketable it is necessary to market the institutions effectively so that all the stakeholders can be aware of what technical colleges can offer. Because of high competition in this industry, it is of vital importance not to be out-marketed by competitors by keeping abreast of new trends in promotional strategies. In order to obtain more relevant information about promotional strategies a literature study was conducted to develop a questionnaire to survey the importance of promotional strategies and determine which promotional strategies are being used by the FET Colleges. The East-London, Queenstown and Ezibeleni Public FET Colleges form the respondents. From each college five academic staff, two management members and five students formed the respondents. Community members, business community members, the Department of Education and the Department of Labour representatives were also included in the sample from each of the selected FET Colleges. The findings of the survey revealed the high level of agreement in terms of the importance of the promotional strategies identified in the literature study with the exception of some promotional strategies, which were identified as not compatible with the FET target market. The study recommended that further research be done on a larger sample size focusing on particular stakeholders eg. students of the FET Colleges in a specific area.

- Description: The Mount Ayliff Complex of the Eastern Cape province of South Africa is a layered intrusion of some 800 km2 surface area and up to 1,200 m thickness. On the basis of compositional similarities and spatial association, it is generally interpreted to form part of the Karoo igneous province. Similarities between the Mount Ayliff Complex and the staging chambers and feeder conduits to flood basalts that host magmatic sulfide ores elsewhere in the world suggest that the Mount Ayliff Complex may have an enhanced potential for Noril’sk-Talnakh–type massive Ni-Cu sulfide ores, an idea that is supported by the well-known sulfide occurrence at Waterfall Gorge.

- Description: Red-billed Quelea Quelea quelea have expanded their range in the Eastern Cape and now occur throughout the year in new areas. Recent changes in agricultural practice have probably been a contributing factor as flocks are larger than previously recorded and were more often associated with artificial food sources than natural grasses. Ringing and census data indicate that quelea have reduced movements during the non-breeding season and may display strong fidelity (over successive years) to dry season quarters with reliable food supplies. Although the recapture/recovery rate for quelea in the Eastern Cape (1.0-2.5%) was higher than the national average, it was still lower than expected and there may be considerable movement between nearby feeding sites. Some quelea breed locally, but most disperse during summer and their numbers at the feedlots were generally highest in winter and spring. The breeding season of quelea is later than other ploceids in the region and post-nuptial moult overlaps with winter. Replacement of primary wing feathers is relatively slow (124 days), and this is considered an adaptation to minimise disruption of flight capabilities and insulation. Significantly more quelea in the Eastern Cape have breeding plumage suffused with pink than in other southern African populations. However, during the non-breeding season there is apparently considerable intermixing between local populations and those from further north and the existence of a local sub-species is not supported. Seeds of two grass species, Echinochloa sp. and Urochloa panicoides, and two weed species, Amaranthus sp. and Chenopodium sp., were important in the diet of both quelea and Laughing Doves Streptopelia senegalensis. Maize comprised a large proportion of the diet of these species and losses at one ostrich feedlot were estimated at over R 17 000 in two years. Dependence on artificial food sources was generally greatest in winter and spring, but economically significant damage was not confined to this period. Alpha-chloralose showed good potential for reducing numbers of problem birds at livestock feedlots. However, the dynamic nature of problem bird populations favours a non-lethal management approach. Reduction of feed loss through manipulation of the ostrich ration could provide a relatively cheap and effective alternative to lethal control if applied appropriately.

- Description: Understanding the mechanisms and adaptations that allow only certain species to thrive in the potentially stressful foredune environment requires a knowledge of the basic ecophysiology of foredune species. Ecophysiological measurements were conducted on the foredune pioneer species Arctotheca populifolia (Berg.) Norl., Ipomoea pes-caprae(L.) R. Br. and Scaevola plumieri (L.) Vahl. and showed significant differences among species with respect to the physiology associated with biomass production, water and nutrient relations. Differences related to CO₂ assimilation included differences in photosynthetic and respiratory rates, susceptibility to light stress and leaf and stem non-structural carbohydrate concentrations. These resulted in differences in primary production rates of shoots. Mechanisms leading to the differences in CO₂ assimilation among species included differences in stomatal behaviour, carboxylation efficiencies, efficiencies of utilisation of incident photosynthetic photon flux density (PPFD) and rates of ribulose-1,6-bisphosphate (RuBP) regeneration. Correlated with differences in photosynthetic capacity were differences in chlorophyll contents but not differences in leaf nitrogen content. Differences in interspecific stomatal behaviour resulted in significantly different transpiration rates which in combination with differences in assimilation rates resulted in differences in water-use efficiency. The absolute amounts of water transpired, although significantly different among species, were moderate to high in comparison with species from other ecosystems and were typical of mesophytes. Transpiration rates in combination with plant hydraulic conductances and soil water availability resulted in leaf water potentials that were not very negative and none of the investigated species showed evidence of osmotic adjustment. The volume of water transpired by each of the species per unit land surface area was estimated from the relationship between abiotic factors and plant water loss. These relationships varied among species and had varying degrees of predictability as a result of differences in stomatal behaviour between the three species. The water requirements of A. populifolia and S. plumieri were adequately met by the water supplied by rainfall and the water stored in the dune sands. It was therefore not necessary to invoke the utilisation of ground water or the process of internal dew formation to supply sufficient water to meet the requirements. However, I. pes-caprae despite its lower transpiration rates and due to its higher biomass, lost greater volumes of water per unit dune surface area than either A. populifolia or S. plumieri. This resulted in periods of potential water limitation for I. pes-caprae. Incident light was the most important determinant of leaf photosynthetic CO₂ assimilation and transpiration, particularly as a linear relationship between incident PPFD and atmospheric vapour pressure deficit (VPD) could be demonstrated. Whole plant photosynthetic production by S. plumieri was shown to be light limited as a result of mutual shading despite high incident and reflected PPFD occurring in the foredune environment. The leaf hair-layer of A. populifolia was shown to be important in reducing transmitted UV and hence reducing photoinhibition but it also caused reduced transpiration rates because of the thicker boundary layer and thus increased leaf temperatures. The nutrient content of above-ground plant parts of the investigated species were typical of higher plants despite the low nutrient content measured for the dune soils. With the possible exception of nitrogen the nutrient demand created by above-ground production was adequately met by the supply of nutrients either from sand-water or from aquifer-water transpired by the plants. Differences in the volumes of water transpired, and hence the quantity of nutrients potentially taken up via the transpiration stream, resulted in interspecific differences in above-ground plant macronutrient content. The reallocation patterns of nutrients differed both between the various nutrients measured and interspecifically. Standing biomass and the density of plants per unit land area was low in comparison to that of other ecosystems and was different among investigated species. This may be important in maintaining the adequate supply of resources (water, nutrients and light). As a result of the interspecific differences in biomass when production was expressed per unit land surface area the resultant productivity was not dissimilar among species. Productivity was high when comparisons were made with species from other ecosystems. No single resource (water, nutrients or light) could be identified as the controlling factor in the foredune environment and a combination of both resource stress and environmental disturbance are likely to be involved. Physiology, production, growth and growth characteristics conveyed certain adaptive advantages to these species in respect to both resource stress and environmental disturbance. Interspecific differences in these adaptations can be used to offer explanations for the observed microhabitat preferences of the three investigated species. Furthermore features common to all three species offer some explanations as to why these species and not others are able to inhabit the foredunes.
