- Description: This study is a case-study of a patient who was diagnosed as having co-morbid Anorexia Nervosa and Factitious Disorder. It would appear that central to an understanding of both of these disorders is the patient's disturbed relationship to her own body. The existing literature on co-morbid Factitious Disorder and Anorexia Nervosa is rare, with only three cases published. A careful reading of these cases suggests that in all of these cases, Factitious Disorder may have been the primary diagnosis. In this case there was as overidentification with the patient role, and the patient's anorexic symptoms appeared to serve the function of meeting the patient's acute dependency needs. Thus, the patient's Anorexia Nervosa masked the Factitious Disorder and appeared to be secondary to the Factitious Disorder. It is argued that these disorders share several common dynamics, namely the inability to separate from the mother, high parental expectations as well as the use of the body as a transitional or pre-cursor object. In addition there are some common dynamics in the psychotherapy of these patients. All of these factors suggest that in both these disorders the developmental arrest may be located at a pre-verbal level.

- Description: To know your law and not to understand it is like a legal barbarian lost in the battlefield of legal theory. A proper and thorough understanding of the law of evidence and hearsay evidence in particular, is of paramount importance not only for lawyers but also for persons who regard themselves as labour law experts. It takes a great deal of experience before a lawyer truly becomes confident with the law of evidence and its application. The only way one becomes good at it is firstly to know the law. (Where does it come from and why is it there?) Then one must get to understand it by looking at examples and apply it in practice. Only then will a person gain practical experience. The aim of this treatise is not to try and educate experienced lawyers. This article is aimed at those that need some motivation to pursue their journey in the labour law process. Remember we all assume that lawyers know and understand their subject until they proof the contrary. In this work I shall try to highlight the importance of the law of evidence in labour law proceedings. Firstly the meaning of the law of evidence and hearsay evidence is considered. Further emphasis will be on the approach and application of the law of evidence, and in particular the hearsay rule, in labour law proceedings.

The bioaccumulation of platinum (IV) from aqueous solution using sulphate reducing bacteria: role of a hydrogenase enzyme

- Description: The enzymatic reduction of a high-valence form of metals to a low-valence reduced form has been proposed as a strategy to treat water contaminated with a range of metals and radionuclides. Metal reduction by sulphate reducing bacteria (SRB) is carried out either chemically (involving reduction by hydrogen sulphide) or enzymatically (involving redox enzymes such as the hydrogenases). While reduction of metal ions by hydrogen sulphide is well known, the enzymatic mechanism for metal reduction is poorly understood. The aims of this study were to investigate the role of SRB in facilitating platinum removal, and to investigate the role of a hydrogenase in platinum reduction in vitro. In order to avoid precipitation of platinum as platinum sulphide, a resting (non-growing) mixed SRB culture was used. The maximum initial concentration of platinum (IV), which SRB can effectively remove from solution was shown to be 50 mg.l⁻¹. Electron donor studies showed high platinum (IV) uptake in the presence of hydrogen, suggesting that platinum (IV) uptake from solution by SRB requires careful optimization with respect to the correct electron donor. Transmission electron microscopy (TEM) and energy dispersive X-ray (EDX) analysis indicated that platinum was being precipitated in the periplasm, a major area of hydrogenase activity in SRB. Purification of the hydrogenase by ammonium sulphate precipitation (65%), Toyopearl-Super Q 650S ion exchange and Sephacry 1 S-100 size exclusion chromatography revealed that the hydrogenase was monomeric with a molecular weight of 58 KDa, when analyzed by 12% SDS-PAGE. The purified hydrogenase showed optimal temperature and pH at 35°C and 7.5 respectively, and a poor thermal stability. In vitro investigation of platinum reduction by purified hydrogenase from mixed SRB culture showed that hydrogenase reduces platinum only in the presence of hydrogen. Major platinum (IV) reduction was observed when hydrogenase was incubated with cytochrome C₃ (physiological electron carrier in vivo) under hydrogen. The same observations were also noted with industrial effluent. Collectively these findings suggest that in vitro platinum reduction is mediated by hydrogenase with a concerted action of cytochrome C₃ required to shuttle the electron from hydrogenase.

The biogeography of the Prosopistomatidae, with a particular emphasis on Southern African species

- Description: The mayfly family Prosopistomatidae consists of the single genus Prosopistoma Latreille. Its known distribution includes species from Africa, Madagascar, the Comores, Europe, the Levant, India, Sri Lanka, China, Vietnam, the Philippines, Malaysia, Sumatra, Java, the Solomon Islands, Papua New Guinea and northern Australia. A tropical Gondwanaland origin of the family has been suggested. No species are currently known from the Neotropical or Nearctic regions, though the family may yet be discovered in northeastern South America, since this region separated from West Africa only c.120 mya. Focussing on southern Africa, several undescribed species have recently been discovered, with interesting implications to the biogeography on a more localised scale. In the western Cape, a prosopistomatid species has been collected in the Olifants River, extending the distribution of this family further south into a more temperate region. Geological evidence indicates that the Olifants River was connected to the Orange River during the Tertiary period. Prosopistomatidae are known from the Orange River today, and the presence of the family in the Olifants River in the western Cape supports the geological evidence of the historical link between these two rivers. Another unexpected discovery was from the Buffalo River in the eastern Cape, at 33ºS. A subtropical zone extends along the east coast of South Africa as a result of the warm Agulhas current offshore, allowing the southerly extension of the distribution of more tropical species. , Research Update on Ephemeroptera & Plecoptera: Proceedings of the Tenth International Conference on Ephemeroptera, 8-11 August 2001, Perugia, Italy.

- Description: In 1891 Lord Randolph Churchill, father of the more famous Winston, visited South Africa and the soon-to-be Rhodesia on a trip that was intended to combine big-game hunting with the even more exciting prospects of entering the gold mining business. During the eight months of the visit, Churchill contributed a series of letters to the Daily Graphic on his thoughts and experiences, in one of which he had this to say about the Boers: The Boer farmer personifies useless idleness. Occupying a farm of from six thousand to ten thousand acres, he contents himself with raising a herd of a few hundred head of cattle, which are left almost entirely to the care of the natives whom he employs. It may be asserted, generally with truth, that he never plants a tree, never digs a well, never makes a road, never grows a blade of corn…. He passes his day doing absolutely nothing beyond smoking and drinking coffee. He is perfectly uneducated. With the exception of the Bible, every word of which in its most literal interpretation he believes with fanatical credulity, he never opens a book, he never even reads a newspaper. His simple ignorance is unfathomable, and this in stolid composure he shares with his wife, his sons, his daughters, being proud that his children should grow up as ignorant, as uncultivated, as hopelessly unprogressive as himself. In the winter time he moves with his herd of cattle into the better pastures and milder climate of the low country veldt, and lives as idly and uselessly in his waggon as he does in his farmhouse. The summer sees him returning home, and so on [sic], year after year, generation after generation, the Boer farmer drags out the most ignoble existence ever experienced by a race with any pretensions to civilization. (94–95) The piece caused an outcry, and when a year later Churchill republished the letters as Men, Mines and Animals in South Africa (1892), he attempted to exonerate himself by claiming that these views were intended “to be exclusively confined to…the Dutch population of the Transvaal,” not “generally to the Dutch in South Africa” and went on: “The Dutch settlers in Cape Colony are as worthy of praise as their relatives, the Transvaal Boers, are of blame. The former, loyal, thrifty, industrious, hospitable, liberal are and will, I trust, remain the back-bone of our great colony at the Cape of Good Hope”

- Description: The pandemic of HIV/AIDS has challenged several aspects of contemporary social life. HIV/AIDS counselling has developed as a social response to provide support for those infected with the disease. Due to the nature and complexity of the disease, HIV/AIDS counsellors encounter a diversity and intensity of emotions when counselling. A support system that includes effective management and supervision may assist in resolving emotions and reactions that HIV/AIDS counsellors may experience as a result of working with HIV/AIDS clients. This study examines the difficulties that both managers and the HIV/AIDS counsellors at a rural district hospital in the Eastern Cape and its surrounding clinics are faced with, in providing the HIV/AIDS counsellors with the support they need. Engestrom's (1987) model of activity theory was used as a conceptual framework guiding both the analysis and interpretation of the data. This model facilitates the identification of tensions and contradictions thereby opening a space for change and transformation within an activity system. Multiple sources of data collection were used that included focus groups with managers and HIV/AIDS counsellors, interviews with senior hospital staff and an official from the Department of Health, Eastern Cape, and a tour of the rural district hospital. The findings suggest that HIV/AIDS counsellors do not feel supported by their managers. Managers in turn are of the opinion that they do not offer the support the HIV/AIDS counsellors' need. The lack of support is attributed to geographic distances between hospitals and the clinics they serve, lack of available transport and the multiplicity of roles of both managers and the HIV/AIDS counsellors.

- Description: The aim of this study was to compare the quality of oral interaction between a grade 5class and their teacher when either English or isiXhosa was used as medium ofinstruction in two different lessons and of their writing which arose out of the lessons. The research was carried out within the interpretive paradigm and took the form of a casestudy. The researcher took the stance of being a non-participant observer. A variety oftechniques were used to collect data, namely, piloting, video recording and transcribing lessons, observing and making field notes, questionnaires and an interview. The interview was recorded and transcribed by the researcher. The two lessons were transcribed and analysed. Also the learners’ writing was analysed. The findings of this study showed that learners have little competence in English compared to isiXhosa. As a result most of them used short and vague sentences when responding to and discussing pictures in English. They also used short and simple sentences when writing in English compared toisiXhosa. Although this is a small-scale study it is recommended that the school’s language policy is revised and teachers are equipped with necessary skills, which would help them teach English to second language learners effectively. It is also recommended that the learners’ first language continue to be well taught even if it is no longer the classroom language.

- Description: The “conjugalisation of reproduction”, in which childbearing is legitimated only within a marital alliance, underlies some of the pathologisation of the single, female-headed household in the pre-democracy South African teenage pregnancy literature. I utilise a poststructural feminist framework that draws on elements of Derrida’s and Foucault’s work to analyse the conjugalisation of reproduction in South African research. The conjugalisation of reproduction relies on (1) the insidious “unwed” signifier which interpenetrates the term “teenage pregnancy”, allowing the scientific censure of non-marital adolescent re-production without the invocation of moralisation, and (2) the fixation of the husband-wife and parents-children axes of alliance as the main elements for the deployment of sexuality and reproduction in the form of the family. Pregnant teenagers are, in Derridean terms, undecidables: they are neither children (owing to their reproductive status) nor adults (owing to their age), but simultaneously both. Marriage is the authority that decides them, allowing them to join the ranks of adult reproductive subjects.

- Description: The right to legal representation at labour proceedings of an administrative or quasi-judicial nature is not clear in our law, and has been the subject of contradictory debate in the South African courts since the1920’s. Despite the ambiguities and uncertainty in the South African common law, the statutory regulation of legal representation was not comprehensively captured in labour legislation resulting in even more debate, especially as to the right to be represented by a person of choice at these proceedings in terms of the relevant entrenched protections contained in the Bill of Rights. The Labour Relations Act 12 of 2002 (prior to amendment) is silent on the right to representation at in-house disciplinary proceedings. Section 135(4) of Act 12 of 2002 allows for a party at conciliation proceedings to appear in person or to be represented by a director or co employee or a member or office bearer or official of that party’s registered trade union. Section 138(4) of the same Act allows for legal representation at arbitration proceedings, but subject to section 140(1) which excludes legal representation involving dismissals for reasons related to conduct or capacity, unless all parties and the commissioner consent, or if the commissioner allows it per guided discretion to achieve or promote reasonableness and fairness. The abovementioned three sections were however repealed by the amendments of the Labour Relations Act 12 of 2002. Despite the repealing provision, Item 27 of Schedule 7 of the Amendment reads that the repealed provisions should remain in force pending promulgation of specific rules in terms of section 115(2A)(m) by the CCMA. These rules have not been promulgated to date. The common law’s view on legal representation as a compulsory consideration in terms of section 39 of the Constitution 108 of 1996 and further a guidance to the entitlement to legal representation where legislation is silent. The common law seems to be clear that there is no general right to legal representation at administrative and quasi judicial proceedings. If the contractual relationship is silent on representation it may be permitted if exceptional circumstances exist, vouching such inclusion. Such circumstances may include the complex nature of the issues in dispute and the seriousness of the imposable penalty ( for example dismissal or criminal sanction). Some authority ruled that the principles of natural justice supercede a contractual condition to the contrary which may exist between employer and employee. The courts did however emphasize the importance and weight of the contractual relationship between the parties in governing the extent of representation at these proceedings. Since 1994 the entrenched Bill of Rights added another dimension to the interpretation of rights as the supreme law of the country. On the topic of legal representation and within the ambit of the limitation clause, three constitutionally entrenched rights had to be considered. The first is the right to a fair trial, including the right to be represented by a practitioner of your choice. Authority reached consensus that this right, contained in section 35 of the Constitution Act 108 of 1996 is restricted to accused persons charged in a criminal trial. The second protection is the entitlement to administrative procedure which is justifiable and fair (This extent of this right is governed y the provisions of the Promotion of Access to Administrative Justice Act 3 of 2000) and thirdly the right to equality before the law and equal protection by the law. In conclusion, the Constitution Act 108 of 1996 upholds the law of general application, if free and justifiable. Within this context, the Labour Relations Act 66 of 1995 allows for specific representation at selected fora, and the common law governs legal representation post 1994 within the framework of the Constitution. The ultimate test in considering the entitlement to legal representation at administrative and quasi judicial proceedings will be in balancing the protection of the principle that these tribunals are masters of their own procedure, and that they may unilaterally dictate the inclusion or exclusion of representation at these proceedings and the extent of same, as well as the view of over judicialation of process by the technical and delaying tactics of legal practitioners, against the wide protections of natural justice and entrenched constitutional protections.

- Description: This article examines the talk of male Psychology students about women and heterosexual relationships in all-male discussion groups. Four vignettes depicting difficult situations in heterosexual relationships were used to initiate discussion. Eight men attending a historically black university participated in the group discussions, which were facilitated by a male postgraduate Psychology student. The study explored masculine identity construction by identifying interpretive repertoires deployed by respondents to construct and account for themselves and their social worlds, within the context of discussions about relationships with women. Three interpretive repertoires of masculinity: the male-as- breadwinner/provider, male-as-protector and the "New Man" repertoire were identified. The complex and contradictory nature of masculine identity construction is highlighted. Drawing on the work of Hollway (1984), two discourses of heterosexuality were also identified: the have/hold discourse and the permissive discourse. The invocation of the "New Man" repertoire and pro-feminist discourses of heterosexuality in the men's talk may signify a move towards more enlightened and less oppressive constructions of masculinity, heterosexuality and gender.

The construction of news texts on 'peace' an analysis of Sunday Times' coverage of the Peace Summits in the Democratic Republic of Congo (August 1998 - January 2001)

- Description: This study examines the construction of news texts on peace and the peace process in the Democratic Republic of the Congo (DRC) in Sunday Times articles dating from August 1998 to January 2001. Peace is an ideological frame that is applied to a complex process that Muller (2000) argues involves and employs a variety of dynamics: diplomacy, economics, force/military intervention and propaganda. As a consequence, different interest groups and nations define peace in different ways. But whatever the definition, the common objective is to restore normalcy via a ceasefire. Peace as a phenomenon has been heightened and sustained by repetitive media attention, thus effectively separating it from international politics (i.e. colonialism of the mind, economy and land), and firmly locating it as a matter of not just public concern, but of international public concern. Using the cultural studies approach to a study of media texts provides a rich foundation for this study. Textual analysis of the articles explores themes and participation and places emphasis on the display of patterns of belief and value that are encoded in the language. What results is a sustained examination of media texts within their socio-cultural and historical context. This study s findings challenge the claim that the media report peace objectively and on its own terms. In particular, the study denies that the Sunday Times objectively, fairly and truthfully reported the experience and process in the DRC between August 1998 and January 2001. Instead it finds that the newspaper constructed a particular understanding of peace, peace talks and the peace process, characterised by repetition, ritualisation and personalisation. Furthermore, this study proposes - and echoes the call for - an alternative news reporting model that will enhance audiences understandings of conflict and its resolution, thereby enhancing the quality of their life.

The decline of agriculture in rural Transkei: ʺthe case of Mission Location in Butterworthʺ

- Description: The following dissertation sets out to investigate the decline of agriculture in Mission location at Butterworth, Transkei, using the Rehabilitation Scheme as a benchmark. The scheme was introduced in 1945 to combat soil erosion and improve agriculture in the African reserve areas, as the South African government claimed. The dissertation argues that this claim by the government served to mask the real intentions behind the scheme namely, to regiment the migrant labour system by depriving as many Africans as possible of productive land so that they were unable to fully subsist by means of agriculture. This is further shown by analysing the impact of the Rehabilitation scheme in Mission location in which a substantial number of people lost arable land as a result of the implementation of the scheme in 1945. These people were consequently denied the wherewithal to subsist by agriculture. Moreover, the efforts of the government resulted to a modernisation of agriculture by making it more cash-based- for example through the introduction of fencing, the need for tractors as a result of a decline in stock numbers (in part as a result of stock culling). Most people could hardly afford this type of agriculture and were consequently forced off the land. The dissertation concludes that indeed the decline of agriculture in Mission location can be linked to the changing agricultural and land-holding practices brought about by the government- especially the introduction of the Rehabilitation scheme.

- Description: A granulovirus isolated from Cryptophlebia leucotreta larvae was shown through restriction endonuclease analysis to be a novel strain (CrleGV-SA). No more than one isolate could be identified from a laboratory culture of C. leucotreta. However, a preliminary examination of restricted DNA profiles of isolates from different geographical regions indicated some minor differences. In surface dose bioassays on artificial diet, LC50 and LC90 values with neonate larvae were estimated to be 4.095 x 103 OBs/ml and 1.185 x 105 OBs/ml respectively. LT50 and LT90 values with neonate larvae were estimated to be 4 days 22 h and 7 days 8 h, respectively. Detached fruit (navel orange) bioassays with neonate larvae indicated that virus concentrations that are likely to be effective in the field range from 1.08 x 107 to 3.819 x 1010 OBs/ml. In surface dose bioassays with fifth instar larvae LC50 and LC90 values were estimated to be 2.678 x 107 OBs/ml and 9.118 x 109 OBs/ml respectively. LT50 and LT90 values were estimated to be 7 days 17 h and 9 days 8 h, respectively. A new artificial diet for mass rearing the host was developed. Microbial contamination of diet was significantly reduced by adding nipagin and sorbic acid to the diet and by surface sterilising C. leucotreta eggs with Sporekill. Almost 20 % more eggs were produced from moths reared on the new diet compared to moths reared on the old diet. A further 9 % improvement in egg production and a reduction in the labour required to produce eggs, was made with the development of a new oviposition cage attached to the moth eclosion box. Virus was mass produced in fifth instar C. leucotreta larvae by surface inoculating diet with the LC90. When 300 individuals were placed onto inoculated diet, 56 % of them were recovered six to 11 days later as infected larvae. Mean larval equivalents was 1.158 x 1011 OBs/larva. When larvae and diet were harvested together, highest yields of virus were achieved at eight days after inoculation. Microbial contamination in semi-purified preparations of CrleGV ranged from 176211 to 433594 (OB:CFU ratio). Half-life of CrleGV in the field was estimated to be less than 1 day on the northern aspect of trees and between 3 - 6 days on the southern aspect. Original activity remaining (OAR) of the virus dropped below 50 % after 5 days on the northern aspect of trees and was still at 69 % on the southern aspect of trees after 3 weeks. In field trials, CrleGV reduced C. leucotreta infestation of navel oranges by up to 60 % for a period of 39 days. CrleGV in combination with augmentation of the C. leucotreta egg parasitoid, Trichogrammatoidea cryptophlebiae, reduced infestation by 70 %. The integration of CrleGV into an integrated pest management (IPM) system for the management of C. leucotreta on citrus is proposed.

- Description: The capsid protein of Helicoverpa armigera stunt virus (HaSV) a T=4 insect virus was expressed in Spodoptera frugiperda 9 cells using a baculovirus vector. When the insect cells were infected at a high MOl the expressed coat protein assembled into virus-like particles (VLPs) that spontaneously underwent maturation and were morphologically indistinguishable from wild-type HaSV. The VLPs were electron dense when viewed under EM and encapsidated their coat protein mRNA. When Sf9 cells were infected at a low multiplicity of infection (MOl) the expressed capsid protein assembled into procapsids that did not spontaneously undergo maturation. These procapsids underwent autoproteolytic maturation cleavage when they were treated with an acidic buffer. The procapsids were used in the encapsidation of a FITC labelled peptide. The peptide encapsidating VLPs showed an increase in their buoyant density that was not collaborated by an increase in the concentration of the FITC labelled peptide detected when these samples were compared to control samples with similar buoyant densities.

The peptide encapsidating VLPs showed an increase in their buoyant density that was not collaborated by an increase in the concentration of the FITC labelled peptide detected when these samples were compared to control samples with similar buoyant densities.

- Description: Limited research has been conducted on financial performance indicators in South Africa. In European countries, Australia and the United States of America, literature has shown that there has been extensive research and implementation of performance indicators, to measure the achievements of objectives. A literature study was conducted for this research on the usage of PI’s, with a view to pinpointing the financial indicators. The literature study was used to develop a questionnaire. The questionnaire was distributed to universities and Technikons in South Africa, to obtain a measure of relevance and agreement on the performance indicators. The findings of the questionnaire culminated in a model that only consists of those indicators with a high level of concurrence among respondents. Performance indicators can serve as a management tool to measure performance and as a means to enhance transparency and accountability.

- Identifier: vital:10913 , http://hdl.handle.net/10948/119 , Sales promotion , Profit
- Description: This paper concerns itself with the devising of a model which organisations can consult when considering hosting any sales promotional activities. The success regarding profits derived from these sales promotions activities vary. These anomalies prompted a further investigation into the need for a single promotional model which could be utilized in varied business environments to optimize profits derived from sales promotions. The uniqueness of the South African environment was also taken into account when considering the various criteria in the development of the model. Sensitivity with regards to the types of barriers peculiar to South Africa is vital. The following excerpt from East Cape Weekend (An Eastern Cape newspaper) reinforces the belief that there are factors to which global environments are not exposed, and thus, the model should and will be designed to cater for these South African peculiarities by virtue of the fact that it will be based on the critical success factors of successful South African retail organisations. Resistance to technological progress due to the threat of possible job redundancy is one of the South African peculiarities that is referred to in the East Cape Weekend 09/06/2001 Michelle Pugh-Parry, “Controversial telephone technology will make paying bills safer”. Besides safety and convenience, the system can alleviate the R600m PE municipal areas debt, yet the union has outwardly rejected the plan and stormed the municipal buildings, protesting that it may cause job loss. It is precisely this type of peculiar barrier to progress that the author intends to accommodate for in the devising of his model. South African organizations will be considered when performing the empirical and primary studies in order to formulate a model that has been adapted to and caters for local needs due to its fundamental aspects being based on the South African circumstance. The information in this study contains the analysis of promotions in a broad context in terms of the following six facets of retail management, namely, operations, human resources, marketing, organizational behaviour, economics and strategies. The results of an analysis of promotional activities used by organizations in the Port Elizabeth municipal area was gained via the application of a questionnaire. An empirical study was performed and provided information that could be used in the development of a promotional model. The application of the model, benefits to whom and importance of the model was debated in the summary, conclusions and recommendations. The table of contents follows.

- Description: The twenty-first century has found education at the crossroads of change. There are burgeoning challenges facing the modern educator. To rise to the importuning, educators find themselves turning to Information Technology for the answers. The technologies utilised in attempts to overcome the challenges often include the Internet and electronic educational resources. Although the Internet is not unduly called the Information Highway, it is also fraught with misleading and incorrect information. Educators’ arduous searches result in few good and useable resources. Thus, to store, organise and efficiently retrieve the discovered resources is a matter of time-saving. The aim of the study was to develop a method to organise and retrieve educational resources in an efficient and personalised manner. In order to do this, an exploration into pedagogy and educational paradigms was undertaken. The current educational paradigm, constructivism, proposes that each learner is an individual with unique learning and personal needs. To develop a new model, the current models need to be understood. The current solutions for the organising of educational resources are realised as several software packages, also called e-learning packages. A list of criteria that describes the essential requirements for organising educational resources was established. These criteria were based upon the pedagogical principles prescribed by educators and the practical technological frameworks necessary to fulfil the needs of the teaching/learning situation. These criteria were utilised to critique and explore the available solutions. It was found that although the available e-learning packages fulfil a need within their genre, it does not meet with the core requirements of constructivism. The resource base model seeks to address these needs by focussing on the educational aspects of resource delivery over an Intranet. For the purposes of storing, organising and delivering the resources, a database had to be established. This database had to have numerous qualities, including the ability to search and retrieve resources with great efficiency. Retrieving data in an efficient manner is the forte of the star schema, while the storing and organising of data is the strength of a normalised schema. It is not standard practice to utilise both types of schemas within the same database. A star schema is usually reserved for data warehouses because of its data retrieval abilities. It is customary to utilise a normalised schema for operational databases. The resource base model, however, needs both the storage facilities of an operational database and the efficient query facilities of a data warehouse. The resource base model, therefore, melds both schemas into one database with interlinking tables. This database forms the foundation (or the back-end) of the resource base. The resource base model utilises web browsers as its user interface (or front-end). The results of the study on the pedagogy, the current e-learning solutions and the resource base were written up within this dissertation. The contribution that this dissertation makes is the development of a technique to efficiently store, organise and retrieve educational resources in such a manner that both the requirements of constructivism and outcomes-based education are fulfilled. To this end, a list of technological and pedagogical criteria on which to critique a resource delivery technique has been developed. This dissertation also elaborates on the schema designs chosen for the resource base, namely the normalised schema and the star schema. From this schema, a prototype has been developed. The prototype’s function was two-fold. The first function is to determine the feasibility of the technique. Secondly, to determine the success of the technique in fulfilling the needs expressed in the list of criteria

- Description: The research problem addressed in this study was to identify the generic strategies that small, medium and micro enterprises (SMME’s) are required to implement in order to achieve competitive advantage in the highly competitive global automotive market. Markets have merged into one huge global marketplace, increasing the competitive forces on all the participants in the automotive markets. Strategies to achieve competitive advantage has changed from the traditional domestic strategies to that of strategies required for global competitive advantage. This has created challenges for SMME’s to attain competitive advantage essential in the fast-changing global markets. The East Cape Motor Industry Cluster (ECMIC) is the heart of the SA automotive industry with three of the major automobile manufacturers having their assembly plants located in the Buffalo and Nelson Mandela Metropoles. A significant number of component manufacturers and their suppliers serve these manufacturers, as well as the other automobile manufacturers located elsewhere in South Africa. Many of these component manufacturers and suppliers are SMME’s. The need to become globally competitive is thus critical for SMME’s in the region. This study investigates the generic strategies that SMME organisations are required to implement in order to achieve competitive advantage in the ECMIC, and based on this and the empirical study that seeks opinion from management of SMME firms in the ECMIC, a model of generic strategies to create competitive advantage is developed.

- Description: This research study addresses the problem of whether local government can afford free basic water in rural areas. To achieve this objective a comprehensive literature study was performed, which included: · Lessons in water sector approaches from international experience and how these experiences compare with the South African situation. 1.The current basic water supply legislation in South Africa and how this legislation affects the subsidy arrangements and the financing of free basic water. 2.The operation and maintenance cost and the benefits of effective operation and maintenance of water supply schemes. A model was developed that could estimate the cost of rural water supply per household per month from the operation and maintenance data that was collected over a period of twenty-two months from a water supply scheme. As part of the provision of free basic water, a nine-step flow chart was developed to determine rural water operation and maintenance subsidy and a free basic water policy to help local government make informed decisions. The model was tested on different water supply schemes to verify the accuracy of the models estimation of the cost of rural water supply per household per month. The information obtained from the literature and from the test of the model resulted in various recommendations and conclusions.
