- Description: Child sex tourism is tourism organised with the primary purpose of facilitating a commercial sexual relationship with a child. It involves a segment of the local child sex industry that is directly connected to both an international and domestic tourist market. The increase of tourism has brought with it complications in that tourism is being used as a means for sex tourists to initiate contact with children. Aside from child sex tourists who are paedophiles, there are those who engage in the opportunistic exploitation of children while travelling on business or for other reasons. There are a number of social and economic factors leading to child sex tourism and the effect is that child victims are exposed to immediate harm, irreversible damage and even death. As South Africa's tourism industry expands into one of the country’s top earners of foreign currency, it is unfortunate to note that its child sex tourist trade is also on the increase. Reports show that sex tours are as easily organised as wine route tours in Cape Town. Commercial sexual exploitation of children is prevalent in South Africa and has become more organised in recent years. A comprehensive response to the problem is essential to ensure that South Africa does not become a “safe haven” for child sex tourists. Effective laws at home and the extraterritorial application of these laws to prosecute South African nationals for crimes committed abroad are imperative. Significant steps are being taken both nationally and internationally to target child sex tourism. South Africa has ratified several international instruments on children’s rights, trafficking in persons, child labour, and discrimination against women and young girls, all of which relate to child sex tourism. In doing so, South Africa has made an international commitment to uphold the provisions of these instruments and give effect to them. South Africa is therefore under an international obligation to create the necessary structures and apply mechanisms and resources to combat child sex tourism.

- Description: The importance of properly securing an organization’s information and computing resources has become paramount in modern business. Since the advent of the Internet, securing this organizational information has become increasingly difficult. Organizations deploy many security mechanisms in the protection of their data, intrusion detection systems in particular have an increasingly valuable role to play, and as networks grow, administrators need better ways to monitor their systems. Currently, many intrusion detection systems lack the means to accurately monitor and report on wireless segments within the corporate network. This dissertation proposes an extension to the NeGPAIM model, known as NeGPAIM-W, which allows for the accurate detection of attacks originating on wireless network segments. The NeGPAIM-W model is able to detect both wired and wireless based attacks, and with the extensions to the original model mentioned previously, also provide for correlation of intrusion attacks sourced on both wired and wireless network segments. This provides for a holistic detection strategy for an organization. This has been accomplished with the use of Fuzzy logic and neural networks utilized in the detection of attacks. The model works on the assumption that each user has, and leaves, a unique footprint on a computer system. Thus, all intrusive behaviour on the system and networks which support it, can be traced back to the user account which was used to perform the intrusive behavior.

- Description: The promulgation into law of the concept of workplace forums has been beset with immense criticism and opposition from organized labour and some quarters of organized business. Last ditch efforts by the Ministerial Task Team had won the day for the inclusion of this controversial provision in the new Labour Relations Act.1 Commentators on the Act tend to agree that the fallout with organized labour at the negotiations has probably set the scene as to whether the provisions would be widely used or not. History has shown that the establishment of such forums in workplaces has been low. In some situations where workplace forums had been established, their continuous sustainability was put into doubt. This has led to the de-establishment of some of these forums in some workplaces. Various reasons were provided, but the prime factors for its failure could be traced back to the negotiations at NEDLAC. The unions opposed the original proposal by government that minority unions and even non-union employees can trigger the establishment of a workplace forum and insisted that this be restricted to majority unions. The voluntary nature regarding the establishment of a workplace forum and the trigger that only a majority union can invoke the provisions has still seen unions reluctant to utilize the provisions since it did not serve their purpose. The aims of the provisions, namely to increase workplace democracy, was therefore thwarted in favour of more informal procedures. Although the idea is a noble one, it is argued that the introduction of the provisions was ill-timed and inappropriate. The lesson that the legislature can take is that for any provision to be a success, buy-in from all stakeholders is paramount. Research has shown that there was a steady decline in the establishment of workplace forums. Since December 2004 there was not a single application received by the Commission for Conciliation, mediation and Arbitration. There is also doubt as to whether any of the Forums that were previously established are still functional. What is certain is that statutory workplace forums is not at the forefront as a vehicle for change that was envisaged in the Explanatory Memorandum that accompanied the new Labour Relations Act. What is also certain is that employers and employees are utilizing other forums to ensure workplace participation. These forums, however, only provide a voice to unionized workers. The vast majority of non-union workers remain voiceless. The proposed amendments in 2002 that intimated that the trigger be any union and not only majority unions failed to be passed into law. Perhaps it is that type of catalyst that is required to give life to the provisions. The future of workplace forums in South Africa is bleak and will continue to be if there is no intervention by the parties at NEDLAC to revive it. A complete revamp of the legislation would be required for such a revival. Some commentators have made meaningful suggestions on changes that can be made to the legislation to make workplace forums more attractive. Some have suggested it be scrapped altogether and future workplace participatory structures should be left to the parties to embrace voluntarily. Workplace forums are a novel innovation with great potential to encourage workplace democracy. There is nothing wrong with the concept. The application of such forums in the South African context is what is concerning. Perhaps prior experience and experimentation with similar type forums have tarnished workplace participation. The strategies by the previous regime and some employers have caused such participation to equate to co-option. Perhaps not enough spade work was done to ensure that the climate and attitude of the parties was conducive for its introduction. What is paramount no matter the form it takes is that workplace participation is crucial for economic growth and the introduction of new work methods to improve productivity. Without the establishment of such forums, whether voluntary or statutory, the ‘second channel principle’ that promotes non-adversarial workplace joint decision-making would be lost and conflict based participation could spiral leading to economic disaster.

- Description: CD23, the low affinity IgE receptor, is expressed by various cell types and has numerous functions depending on the form of the protein, its interaction with various ligands and the type of cell involved. CD23 is pivotal in the regulation of IgE, with the soluble form involved in up-regulation, while the membrane bound form is involved in the down-regulation. It is clear why it is believed to be a central molecule in allergic responses, and a therapeutic target for the treatment of allergic disease. In this study a recombinant form of the entire extracellular domain of the protein, exCD23, was produced by PCR cloning and expressed in E. coli. His•Tag™s were introduced onto the C-terminus and N-terminus, respectively, in order to simplify the purification procedure. After renaturation and purification, the recombinant exCD23 bound IgE, indicating its activity. From the IgE binding studies it was established that the position of the tag did not influence the binding. GST•Tagged™ exCD23 was also produced in an attempt to increase the solubility of the recombinant protein, but this proved unsuccessful. Butyrate differentiated EoL-1 cells were treated with the Nterminal His•Tagged™ exCD23, and the protein appeared to suppress the secretion of the constitutively expressed cytokines, especially IL-8 and IFN- , when compared to untreated cells. In addition, treatment of the EoL-1 cells with exCD23 had a significant proliferative effect, but could not induce differentiation of this cell line into mature eosinophilic-like cells.

- Description: Many academic studies in the past have focussed on how to create value for businesses in terms of adding profit to the bottom line through performance, and many argue that adding value for the client is also viewed as a profitable business strategy. This strategy translates as a win-win business relationship since long-term relationships ensure customer loyalty, customer retention and repeat business. In the services sector, it is difficult to quantify the worth or value that a particular service has since services are intangible products. The perception of value of such a service is known as “perceived value” since value recognition rests with the consumer who attempts to quantify the worth of that service. It is generally accepted in the services sector that establishing long-term, mutually beneficial, meaningful business relationships add value for the client and helps them to attach a value to the services that company provides. A company cannot establish such relationships without the help of its employees who represents the face of the organisation and implements the value adding strategy on the organisation’s behalf. Recent studies have begun to address this, examining value creation in business relationships in the context of the sale of tangible goods. The process of value creation for customers in services relationships remains underresearched. Perceived value explains why customers choose one particular service over another, why service companies gain competitive advantage by maintaining genuine longterm customer relationships, and why “the personal touch”, created through emotional attributes such as trust, caring and empathy, adds value from customers’ perspective. This dissertation presents a study of perceived value from the perspective of the customer within the context of the delivery of a credence product in a services relationship model. Using grounded theory methodology; following in-depth interviews with consumers of general insurance, a number of customer-value creation dimensions for businesses have been identified. Parallel interviews with members of staff from the supplier company add a further perspective. This research demonstrates how organisations or suppliers in the services industry can add value when delivering a credence product in a services relationship context. It is believed that an understanding of the value-adding dimensions can be implemented to create opportunities to build value for customers, with commensurate benefits for suppliers. Following analysis of the interviews held with each buyer, a total of six value dimensions are identified in the findings chapter. Each dimension is individually described, discussed, and illustrated with quotations from customers and supplier’s staff. Other issues relating to value arising from the interviews are examined in the discussion chapter. Three areas for further research are proposed in the conclusion.

- Description: This research study endeavoured to explore and describe the experiences of women who participated in the Prevention of Mother-To-Child Transmission (PMTCT) of HIV Programme. Data relating to evaluation of the PMTCT Programme in the piloted sites compiled by other researchers in the Department of Health focus on the process, progress and extent of service implementation. There appears to be a dearth of information available from women participants in the PMTCT Programme. The objectives of the study were to: · Explore and describe postnatal women’s experiences of the PMTCT Programme offered in the East London Hospital Complex. · Propose recommendations into the existing guidelines for midwives who implement the PMTCT Programme in the health services to ensure optimal implementation of this programme. The research population included postnatal women who participated in the PMTCT of HIV Programme at the East London Hospital Complex (Frere site). Permission to conduct the research was obtained from the Eastern Cape Department of Health Ethics Committee, Chief Executive Officer of the hospital complex and the Advanced Degrees Committee and Human Ethics Committee at the Nelson Mandela Metropolitan University. The research study was qualitative, exploratory, descriptive and contextual in design. Data collection was carried out by face-to-face semi-structured interviews with postnatal women at the East London Hospital Complex (Frere site). The tape-recorded interviews were transcribed verbatim with the aid of field notes. Data analysis was done according to Tesch’s method of data analysis (in De Vos et al, 2000:343). Themes were identified from the transcriptions and finalised after consensus discussions with an independent coder who was experienced in qualitative research. Literature control, guided by the themes identified in the interviews, was carried out to compare and verify the findings of the study. Three major themes with sub-themes were identified during data analysis. The major themes were identified as follows: · The participants expressed feelings of being devastated by the results that confirmed their HIV positive status. · The participants expressed a thirst for knowledge on how to live with the diagnosis and on how to continue with the PMTCT Programme. · The physical environment where counselling and testing were done, as well as the practical arrangements, were not conducive to the full implementation of the PMTCT Programme at the antenatal clinic. Conclusions were drawn and recommendations were made in the form of additional guidelines for midwives implementing the PMTCT Programme in the antenatal clinic health services. Guidelines for further midwifery-related research were formulated.

- Description: The Orange River is an important source of freshwater and like many other wetlands in semi-arid regions, supports various social (Spurgeon, 1998), economic (Spurgeon, 1998; Bornman et al., 2005) and ecological functions. The saltmarsh at the Orange River Mouth has become degraded over time following numerous anthropogenic impacts. As a result the Transboundary RAMSAR site was placed on the Montreux record emphasising the importance for rehabilitation. The potential of the marsh for natural rehabilitation was assessed through three physical factors which were considered to have the most influence on the saltmarsh i.e. 1) sediment 2) water 3) wind. Three sampling areas were chosen to investigate the sediment characteristics of the ORM saltmarsh and the suitability for seed germination and adult survival. Site A was representative of the general marsh area, Site B was thought to have favourable sediment conditions for saltmarsh growth because of the large numbers of seedlings and Site C was prone to inundation by wind blown sediment. The sites were sampled in 2005 (dry conditions) and in 2006 after high rainfall and river flooding. Electrical conductivity (EC) of the sediment throughout the marsh was hypersaline in many instances above the tolerance range for S. pillansii (> 80 mS.cm-1) The freshwater event in 2006 lowered salinity significantly in two of the three sites. Differences in sediment characteristics were also compared for three habitats i.e. driftlines, open sites and under vegetation. Driftlines (C. coronopifolia = 872 seedlings m-2; S. pillansii = 1296 seedlings m-2) and the microhabitat associated with adult plants (C. coronopifolia = 803 seedlings m-2; S. pillansii = 721 seedlings m-2) created favourable conditions for seedling growth, however open unvegetated (C. coronopifolia = 56 seedlings m-2; S. pillansii = 49 seedlings m-2) areas had significantly lower seedling density. Due to the marsh currently being in a desertified state this study aimed to establish whether the remaining vegetation could produce enough seed to revegetate the marsh. Laboratory studies indicated that seeds of both species germinated best in freshwater (0 psu). The germination of S. pillansii seeds was 40 percent at 0 psu compared to 5 percent at 35 psu. After storage under hypersaline conditions (35 psu) C. coronopifolia showed 100 percent seed germination when returned to freshwater whereas storage at 70 psu decreased the viability of S. pillansii seeds. The plants are producing adequate seed that will allow for regrowth and rehabilitation if sediment and groundwater characteristics are suitable for seed germination, seedling growth and adult survival. However the increase in bare areas at the Orange River mouth as a result of salt marsh dieback has increased the available sediment source. The wind blown sediment has covered large areas of the remaining adult salt marsh vegetation, particularly in the northern corner at Site C, causing further die-back.

- Description: The Orange River is an important source of freshwater and like many other wetlands in semi-arid regions, supports various social (Spurgeon, 1998), economic (Spurgeon, 1998; Bornman et al., 2005) and ecological functions. The saltmarsh at the Orange River Mouth has become degraded over time following numerous anthropogenic impacts. As a result the Transboundary RAMSAR site was placed on the Montreux record emphasising the importance for rehabilitation. The potential of the marsh for natural rehabilitation was assessed through three physical factors which were considered to have the most influence on the saltmarsh i.e. 1) sediment 2) water 3) wind. Three sampling areas were chosen to investigate the sediment characteristics of the ORM saltmarsh and the suitability for seed germination and adult survival. Site A was representative of the general marsh area, Site B was thought to have favourable sediment conditions for saltmarsh growth because of the large numbers of seedlings and Site C was prone to inundation by wind blown sediment. The sites were sampled in 2005 (dry conditions) and in 2006 after high rainfall and river flooding. Electrical conductivity (EC) of the sediment throughout the marsh was hypersaline in many instances above the tolerance range for S. pillansii (> 80 mS.cm-1) The freshwater event in 2006 lowered salinity significantly in two of the three sites. Differences in sediment characteristics were also compared for three habitats i.e. driftlines, open sites and under vegetation. Driftlines (C. coronopifolia = 872 seedlings m-2; S. pillansii = 1296 seedlings m-2) and the microhabitat associated with adult plants (C. coronopifolia = 803 seedlings m-2; S. pillansii = 721 seedlings m-2) created favourable conditions for seedling growth, however open unvegetated (C. coronopifolia = 56 seedlings m-2; S. pillansii = 49 seedlings m-2) areas had significantly lower seedling density.

- Description: The purpose of this study was to investigate the feasibility of an Indoor Aquatic Centre for the Nelson Mandela Bay Metropole. The main problem was to establish the minimum aquatic facilities an Indoor Aquatic Centre must have, to be able to host National and International aquatic events. The sub problems identified to address the main problem were as follows: - Should accommodation be available at the Indoor Aquatic Centre? - Should medical facilities be available at the Indoor Aquatic Centre? - Should there be a gymnasium at the Indoor Aquatic Centre? - Should there be food malls available at the Indoor Aquatic Centre? - Will sports tourism in the Nelson Mandela Bay Metropole benefit from an Indoor Aquatic Centre? In this study the researcher discusses current tourism opportunities, possible sports tourism opportunities and the current aquatic facilities the Nelson Mandela Bay Metropole has to offer. From the discussion regarding these issues it was found that the metropole do offer many attraction opportunities including the following: - Adventure and Sport; - Agriculture; - Arts and Culture; - Business and Conferencing; - Coastal and Beaches; - Entertainment and Shopping; - Historical; - Wild Life and Nature. Adventure and Sport attractions contribute to sports tourism in the metropole and an Indoor Aquatic Centre could enable the metropole to improve sports tourism figures to the metropole. Sports tourism is defined as any tourism that is linked with a sports event. The conclusion can be made that the main initiative for sports tourism is to host a major sporting event to attract tourists. Adding other tourist attractions makes the destination more attractive. It is also important that the community is educated and informed about sports tourism so that the tourist and the community benefits from the event. Indoor Aquatic Centres found in countries like Australia, Canada, Europe, Russia, The Far East, United Kingdom and the United States of America, were discussed to identify the minimum requirements for an Indoor Aquatic Centre. The literature study has shown that the Indoor Aquatic Centre should be a multi purpose centre with a minimum of two heated pools and leisure facilities included. This will enable the centre to generate different streams of income to enhance sustainability. The aquatic centre should also be designed to host National and International events, but not necessarily for Olympic Games events. An empirical study was done to see if the respondents agree on the minimum requirements for an Indoor Aquatic Centre, identified by the literature study and if they agree that sports tourism within the Nelson Mandela Bay Metropole will benefit from an Indoor Aquatic Centre. The conclusion of the empirical study is that the respondents’ view correlate with the information found during the literature study regarding the minimum requirements for an Indoor Aquatic Centre listed as follows: - The minimum number of heated pools are two consisting of a fifty metre ten lane pool and a twenty five metre ten lane pool; - A food mall that consists of a restaurant, fast food stalls and a food store; - Medical facilities, conference facilities, gymnasium and other leisure facilities must also be available; - Accommodation facilities must be available and consists of two and three bedroom fully serviced apartments; - The Indoor Aquatic centre must be able to have seating for 2000 people and parking for 1000 vehicles. The study has addressed the main problem and the sub problems, but further research needs to be conducted regarding the funding of the Indoor Aquatic Centre as this issue was not successfully addressed. More information is needed regarding the different ways of funding and who the stakeholders should be in this process.

The constitutional right to food in South Africa

- Description: This dissertation is a study of the ambit of the right to food as it is contained in the South African Bill of Rights and the steps needed to realise the right. Existing and potential food insecurity, hunger and malnutrition provide the social context for this research. The rationale for conducting the research is primarily two-fold. Firstly, the access to sufficient food is an indispensable right for everyone living in this country. Secondly, the right to food in South Africa has not been subject to extensive academic study to date. Socio-economic rights are fully justiciable rights in this country, equally worthy of protection as civil and political rights. Furthermore, socio-economic rights (like the right to food) are interdependent with civil and political rights: neither category can meaningful exist without realisation of the other. The right to sufficient food is found in section 27(1)(b) of the South African Constitution. Children have the additional right to basic nutrition in terms of section 28(1)(c). The right to sufficient food is subject to the internal limitation of section 27(2) that the state must take reasonable measures, within its available resources, to achieve the progressive realisation of the right. Furthermore, as with all rights in the Bill of Rights, both these rights are subject to the general limitations clause found in section 36. There is international law authority in various human rights instruments for the protection of the right to food and what the right entails. In accordance with section 39 of the Constitution, such international law must be considered when interpreting the right to food. It is argued that a generous and broad interpretation of food rights in the Constitution is called for. Existing legislation, state policies and programmes are analysed in order to gauge whether the state is adequately meeting its right to food obligations. Furthermore, the state’s food programmes must meet the just administrative action requirements of lawfulness, reasonableness and procedural fairness of section 33 of the Constitution and comply with the Promotion of Just Administrative Justice Act. The dissertation analyses the disparate and unco-ordinated food and law policies in existence, albeit that the National Food Security Draft Bill offers the hope of some improvement. Particular inadequacies highlighted in the state’s response to the country’s food challenges are a lack of any feeding schemes in high schools and insufficient food provision in emergency situations. Social assistance grants available in terms of the Social Assistance Act are considered due to their potential to make food available to grant recipients. On the one hand there is shown to be a lack of social assistance for unemployed people who do not qualify for any form of social grant. On the other hand, whilst presently underutilised and not always properly administered, social relief of distress grants are shown to have the potential to improve access to sufficient food for limited periods of time. Other suggested means of improving access to sufficient food are income generation strategies, the introduction of a basic income grant and the creation of food framework legislation. When people are denied their food rights, this research calls for creative judicial remedies as well as effective enforcement of such court orders. However, it is argued that education on what the right to food entails is a precondition for people to seek legal recourse to protect their right to food. Due to a lack of case authority on food itself, guidance is sought from the findings of South Africa’s Constitutional Court in analogous socio-economic rights challenges. Through this analysis this dissertation considers the way forward, either in terms of direct court action or via improved access to other rights which will improve food access.

- Description: Schizophrenia cuts across all racial, gender, and socioeconomic lines. Schizophrenia affects 1 percent of the population in Ireland: 35000 people (Schultz & Andreason, 1999); and affects 1.4 - 4.6 percent per 1000 people in the USA: 2.8 million - 9.8 million people (Jabelensky, 2004). In South Africa the figure is approximately 1 percent of the population or 500 000 people (Nicholas, Malcolm, Krosigk & Pillay, 2003). The median age of onset is 21.4 years for men and 26.8 years for women (Daubenton & van Rensburg, 2001), with only 10-20 percent recovering fully after the first psychotic episode (Saddock & Saddock, 2003). The schizophrenic patient is often unable to continue life as before diagnosis, and may progressively need more care as the years pass. Deinstitutionalization over the course of a number of decades has resulted in responsibility for care of mentally-ill individuals shifting to the individual’s family. The struggles faced by such a family can be overwhelming as they struggle with this responsibilty due to lack of training, lack of knowledge and insufficient professional support (Winefield & Harvey, 1994). The stress on the caregivers is often magnified as their support structures around them may ‘shut down’ out of fear of the schizophrenic illness (Williams & Mfoafo-M’Carthy, 2006). The characteristic symptoms used to define schizophrenia include various forms of delusions, hallucinations, thought disorders and abnormalities in emotional expression, social interaction, attention, volition and drives. The functional decline of the schizophrenic individual leads not only to social difficulties, but also economic difficulties that may cripple a family (Fadden, Bebbington & Kuipers, 1987). When first diagnosed, some families may be so overwhelmed by the ‘label’ given to their family member, that they see little hope or way to move forward. One explanation is offered by an American psychiatrist whose own son was diagnosed with schizophrenia, “We experience this terrible feeling of loss and grief for the son we knew. There is also this terrible loss of expectations. We feel cheated out of watching him mature…it is a mourning without end because, of course, Gary is not dead at all. He is very much still with us, seeming eternally twelve years old, needing constant care and attention” (Willick, 1994, p.14). Providing such care is associated with high levels of distress. Accordingly, much attention has been given to understanding the pressures faced by family members, with the hope of understanding how coping resources may be strengthened to sustain these care-giving relationships (Harvey, Burns, Fahy, Manley & Tattan, 2001). However, despite gains in understanding the needs of a schizophrenic family member once out of the hospital environment, care-giving relationships can still break down. The individual with the illness is often left more vulnerable to relapse, recurrent hospitalizations, homelessness and other negative outcomes (Jewel & Stein, 2002). The stress of not only interacting with the afflicted family member, but also with the grief associated with the illness, places an incredible strain on the day-to-day functioning of that family (Pollio, North, Reid, Miletic & McClendon, 2006). From the brief review provided, it is evident that research has been conducted regarding the stressors, strains and difficulties of caregivers of schizophrenic family members. However, the strengths of these families are under-investigated, and the current study will attempt to start filling this void.

- Description: Over the past couple of decades traditional manufacturing techniques have been replaced by lean production around the world. This change in production methodology brought about the opportunity for numerous companies to reduce costs and customer lead time through the application of this lean philosophy. The worldwide shift from traditional manufacturing to lean manufacturing can be ascribed to the success of Toyota Motor Company. Lean manufacturing refers to a manufacturing improvement process in order to minimize or eliminate waste while maximizing production flow (Tapping, et al., 2002:30). A value stream includes all the operations and processes to transform raw material into finished products or services. Value stream is a management tool used for the planning of a production process involving lean techniques through systematic data capturing and analysis (Tapping 2002 et al., 41). Value stream is a proven process for planning the improvements that will allow companies to develop lean practices. One key to Toyota’s success that GMSA and many other South African companies have not been able to emulate is the transformation of their suppliers to apply the lean philosophy. This lack of supplier transformation is due to various reasons including supplier proximity, supplier relationships, supplier performance levels, and the ordering policies used for supplied parts. Even though many manufacturing organizations realize the importance of practicing lean manufacturing techniques, few organizations apply lean techniques with the required knowledge and tools to transform their organization from traditional manufacturing to lean manufacturing. This research project is based purely on the lean manufacturing principles and philosophies. The aim of the study is to make GMSA’s suppliers aware of the principles and processes of lean manufacturing and to develop a lean implementation strategy to assist organizations with the successful implementation of lean practices. In order to correctly implement and sustain lean manufacturing practices this study will also focus on supplier support and development and the behavior an organization must exhibit to make this transformation a success. The research methodology comprised the following steps: • A literature study was performed by the researcher to get a better understanding of the principles and philosophies of lean manufacturing; • A second literature study was also performed to get a better understanding of the continuous improvement philosophies of lean manufacturing including supplier support & development; and • To accomplish the objectives of this study, interview sessions were conducted with four senior managers of General Motors South Africa. The researcher selected the interviewees from the following departments within General Motors South Africa: Global Purchasing and Supply Chain; Supplier Quality and Development; Vehicle Assembly Operations and Material Supply. The interviewees from General Motors South Africa were identified as qualified data sources for this research project, as their professional opinions and viewpoints could best address the research questions.

Value stream is a management tool used for the planning of a production process involving lean techniques through systematic data capturing and analysis (Tapping 2002 et al., 41). Value stream is a proven process for planning the improvements that will allow companies to develop lean practices. One key to Toyota’s success that GMSA and many other South African companies have not been able to emulate is the transformation of their suppliers to apply the lean philosophy. This lack of supplier transformation is due to various reasons including supplier proximity, supplier relationships, supplier performance levels, and the ordering policies used for supplied parts. Even though many manufacturing organizations realize the importance of practicing lean manufacturing techniques, few organizations apply lean techniques with the required knowledge and tools to transform their organization from traditional manufacturing to lean manufacturing. This research project is based purely on the lean manufacturing principles and philosophies. The aim of the study is to make GMSA’s suppliers aware of the principles and processes of lean manufacturing and to develop a lean implementation strategy to assist organizations with the successful implementation of lean practices. In order to correctly implement and sustain lean manufacturing practices this study will also focus on supplier support and development and the behavior an organization must exhibit to make this transformation a success. The research methodology comprised the following steps: • A literature study was performed by the researcher to get a better understanding of the principles and philosophies of lean manufacturing; • A second literature study was also performed to get a better understanding of the continuous improvement philosophies of lean manufacturing including supplier support & development; and • To accomplish the objectives of this study, interview sessions were conducted with four senior managers of General Motors South Africa. The researcher selected the interviewees from the following departments within General Motors South Africa: Global Purchasing and Supply Chain; Supplier Quality and Development; Vehicle Assembly Operations and Material Supply. The interviewees from General Motors South Africa were identified as qualified data sources for this research project, as their professional opinions and viewpoints could best address the research questions.

- Description: It is an acknowledged fact that many novice programmers experience difficulty in the process of learning to program. One of the contributing factors to this difficulty is the Program Development Environment (PDE). Professional-PDEs are those developed specifically for professional programmers, but are often used by educational institutions in the instruction of programming. It has long been accepted that such environments are inappropriate in the instruction of programming due to unnecessary complexity and lack of support for novice programmers in the learning process. Numerous pedagogical-PDEs supporting the mechanics of programming have been developed in response to this. A review of literature, however, indicates that very limited empirical studies comparing pedagogical-PDEs and professional-PDEs have been conducted. The current study investigates whether there are measurable benefits to using a pedagogical-PDE supporting the mechanics of programming in the instruction of programming instead of a professional-PDE. A comparative study of this nature requires a representative pedagogical-PDE and representative professional-PDE be compared with one another. The first part of the current study determines a set of requirements that a pedagogical- PDE should adhere to based on literature. A set of representative features for a pedagogical-PDE is derived by examining the features of existing PDEs in conjunction with the set of requirements. Based on these features, a pedagogical-PDE, known as SimplifIDE, is developed that implements the representative set of features and that meets are the requirements for a pedagogical-PDE. The second part of the current study is the specification and administration of an empirical experiment in which SimplifIDE and Borland© DelphiTM are compared with one another. A holistic approach in determining the differences between the PDEs is taken and three main areas are examined, namely academic performance, perceptions and programming behavior.

- Description: This dissertation proposes the development of an identification verification model that can be implemented within the context of the Eastern Cape, South Africa in order to ensure that vulnerable children are provided with the requisite care that they deserve from the state. The dissertation provides both a developed and developing world perspective on the identification verification needs of vulnerable children by providing an overview of relevant South African policy with regard to caring for vulnerable children and presenting an international perspective with specific reference to current legislative developments in the United Kingdom and Malaysia. Chapter 1 provides a motivation for a framework to be used for the identification verification of children in developing countries by emphasising that the provision of basic social services to children is an urgent requirement for poverty eradication and is a necessity as documented in the United Nations Convention on the Rights of the Child. A background to the needs of vulnerable children in South Africa is given and the scope, limitations and research methodology used in the dissertation is presented. Chapter 2 provides an overview of child related policy in the South African Context both from a National Government and Eastern Cape perspective. Although extensive progress has been made in the development of policies aimed at protecting vulnerable children, the practical implementation of these policies has been hampered by numerous issues including the lack of coordination between key entities. Chapter 3 provides an introduction to several noteworthy international developments with regard to the identity verification of vulnerable children. Lessons learnt from identity verification systems from the United Kingdom and Malaysia are analyzed for applicability to the South African context. In addition to this, the use of biometric technology in identity verification systems and a number of biometric identification methodologies available are discussed. Chapter 4 proposes the development and implementation of a biometric identity verification model in the Eastern Cape Province of South Africa based on lessons learnt from the assessment of South African policy and international best practice. The system should be piloted in the Eastern Cape and, if successful, be implemented throughout South Africa with a possible view to future implementation on the African continent. The scope of the system, the technological requirements and a high level implementation plan together with the need to further research certain key aspects e.g. the cost implications are discussed. It is clear that the development of such a model and the implementation of such a system will ensure that vulnerable children are provided with the requisite care that they are constitutionally entitled to. Significant follow up research is required during the development of the model to ensure that all aspects of the model are well documented and during the implementation of the system to ensure that the requirements of the users both within the government and the general public are met.

- Description: Child assessment has become imperative today as parents and teachers recognize the need for early diagnostic assessments to adequately cater for children’s’ diverse and growing needs so that children can benefit from services and attention in a psychological or educational setting. The Griffiths Mental Development Scales, an established and well-researched instrument is reported to be one of the most carefully designed measures of child development . Studies in various parts of the world have demonstrated that the Griffiths Scales are applicable to diverse populations and that they tap experiences that are common to different cultures. The recent revision and restandardisation of the Griffiths Mental Developmental Scales-Extended Revised (GMDS-ER) has necessitated investigations into its psychometric properties. In view of the important role that assessment measures play in the early identification of developmental delays, it is important that assessment measures are reliable and valid for their intended purpose(s). This study, which is part of a larger research project, attempted to explore and add further evidence of the construct validity of one of the six Subscales of the GMDS-ER, namely the Personal-Social Subscale (Subscale B). An exploratory-descriptive design using a triangulation approach was utilized to explore the construct validity of the Personal-Social Subscale. A nonprobability purposively selected sample of 18 experts working with children participated in the facet analysis to identify the constructs underlying Subscale B (the qualitative aspect of the study). The sample for the quantitative aspects of this study (i.e., the empirical validation of the identified constructs) was collected as part of the broader restandardisation and represented a stratified random sample of 1026 children between the ages of 3 and 8 years from across the United Kingdom and Eire. Three measures, namely a biographical questionnaire, the GMDS-ER and a construct evaluation form were used to gather the qualitative and quantitative data. The qualitative data was analysed by means of facet analysis and literature control. The quantitative data was analysed by using exploratory common factor analysis using oblique (DQUART) rotation to empirically verify the qualitatively identified construct model by specifying a onefactor solution for each underlying construct.

- Description: Optimal management of a chronic disease, like asthma, requires the active participation of patients. To achieve this, patients require education about asthma. Many of the recommended components of asthma care and management might not be effective without adequate patient education. Pharmacists in community, hospital and clinic practice are well placed to provide continued information and reinforcement of key messages, in order to improve compliance with medication and the outcomes of asthma management plans. Pharmacists may be able to increase medication adherence with patient counselling and monitoring systems and by facilitating communication with physicians. However, regardless of this, it remains uncertain whether pharmacist-patient interactions improve patient outcomes, and in spite of recommendations for teamwork and a multidisciplinary approach in the education of asthma patients, medical doctors and nurses are still largely responsible for carrying out the greatest part of patient education. The objectives of this study were therefore to determine the impact of pharmaceutical care services at a primary health care level on the management and well-being of asthmatic patients; to determine the effect of complex or multi-faceted pharmaceutical interventions, in patients with asthma, on lung function, asthma knowledge, attitudes and perceived self-management efficacy, asthma related quality of life and asthma control; and to determine the extent to which pharmacotherapeutic interventions, with regards to medication changes and dosage changes, are accepted and implemented by doctors. A randomised-control study was conducted at a primary health care clinic in the Eastern Cape. A total of 120 patients were allocated to two groups of sixty patients each (a Control Group and an Intervention Group). Baseline values were measured and follow-up interviews and post-intervention data collection were conducted three months afterwards for each group. Patients in the Control Group were attended to by the clinic staff as usual. Patients in the Intervention Group were educated on their disease by a pharmacist. The use of a customised 500ml plastic bottle as a spacer was suggested and each patient’s medication was evaluated against the Standard Treatment Guidelines for the management of asthma in adults at the primary health care level and where necessary, prescribing recommendations were made. Following assessment of the medication regimens of the patients in the Intervention Group, a total of 49 prescribing recommendations were made, of which 73 percent were accepted by both the doctor and patient. After educating the patients in the Intervention Group on inhaler technique, a significant improvement in technique was observed at the 3-month follow-up assessment (p<0.05). Using a short form of the Asthma Quality of Life Questionnaire (AQLQ(S)), a significant improvement post-intervention in mean total quality of life score (p<0.05) and mean average quality of life score (p<0.05) in the Intervention Group, were demonstrated. An improvement in mean activity limitation score in the Intervention Group post-intervention was also recorded for the activity limitation subscale of the AQLQ(S) (p<0.05). On measuring changes in asthma related knowledge, attitudes and self-efficacy, using a questionnaire (KASE-AQ), a significant improvement in mean knowledge score in the Intervention Group after the intervention (p<0.05) was also shown. With regards to lung function, both vital capacity (percent FVC) and expiratory flow volumes (percent FEV1) improved significantly in the Intervention Group (p<0.05). This study therefore demonstrated that multi-faceted pharmacist interventions, including medication assessment, asthma education, education on inhaler technique and the provision of medication aids in the form of spacers, can significantly improve the management of asthma patients and improve their well-being and quality of life.

- Description: Friction Stir Processing (FSP) of aluminium alloys has been used to modify and improve the microstructure and relevant properties of fusion welded aluminium alloys. The effect of FSP on MIG-Laser Hybrid (MLH) welded aluminium alloy 6082-T6 mechanical and microstructural properties has been studied in this research. The FSP process was used on 6mm thick aluminium alloy plates and a tool was designed specifically for FSP, and the effect of varying speeds was analysed before the final FSP welds were made. The effect of FSP was analysed by optical microscopy, tensile, microhardness and fatigue testing. The aim of the study was to determine whether the FSP process has a beneficial influence on the mechanical properties and metallurgical integrity of MIG-Laser Hybrid welded 6082-T6 aluminium alloy with varying gap tolerances. Three welding processes were compared, namely combined Friction Stir Processing on MIG-Laser hybrid process (FSP-MLH), MLH and Friction Stir Welding (FSW) as part of the analysis. (FSP was carried out on MLH components when it was found that FSP is not an entirely complete welding process but rather a finishing process per se.) The aim of this dissertation is to investigate the effects of the FSP process on the weld quality of MLH welded joints and also to compare this to individual processes like FSW and MLH. This investigation was undertaken in order to gain an understanding of the effect of these processes on fatigue performance and microhardness distribution on aluminium alloy 6082-T6 weld joints.

- Description: The focus of this research was to establish how black primary school principals in some Port Elizabeth schools manage the problems of poverty, vandalism and non-payment of school fees. The aim of this research was to improve these burning issues at my own school, but also to assist other schools which are encountering similar problems with regard to these three issues. Qualitative research methods were used. Data was collected by studying relevant literature and conducting semi-structured interviews and participant observation. Composite case studies of the schools were compiled. Content analysis was used to analyse the data and recommendations for improvement were made. The results of the research indicate that since 1994, when democracy and equal human rights were declared, primary schools have actually been experiencing escalating problems in terms of poverty, vandalism and school fee payment. As the school system is closely intertwined with the socio-economic and political dimensions of society, these challenges can only be effectively addressed if all stakeholders in education collectively take up ownership of these problems and commit themselves to finding unique and effective solutions in the Port Elizabeth urban and rural areas.

- Description: It is clear that the concept of inclusive education implies that learners experiencing barriers to learning should, wherever possible and with suitable support, be educated with others in a regular school setting and through a regular curriculum. It is assumed that suitable facilities, resources and assistance, where needed, will be available. An adaptable curriculum that accommodates the specific learners who experience barriers to learning is also essential for inclusive education. The focus on providing equal educational opportunities for learners experiencing barriers to learning means that the traditional roles and responsibilities in education will inevitably change. Teachers have to modify their views of themselves, their teaching methods and the roles that they have to play during the implementation of inclusive education. Teachers will have to be adequately trained to effectively and confidently provide appropriate education to learners experiencing barriers to learning. The primary goal of the study is to explore the experiences, perceptions and needs of teachers regarding inclusive education. The secondary goal is to develop a training model to equip in -service teachers better for inclusive education. The research process was structured by the application of a qualitative research approach within a theory generative design, utilising five steps of theory generation in order to reach the objectives of the study. The qualitative approach was selected, as it is exploratory in nature. Founded in this exploratory research, a central concept was identified, with the aim of developing a model to assist teachers in implementing inclusive education. ABSTRACT (xvii) The research was conducted in two phases. The first section of the research comprised an exploration of the experiences, perceptions and needs of teachers regarding inclusive education. It embraced several decisions relating to data collection and analysis processes, such as defining the population and selecting the sample procedure and the data collection method, namely personal interviews with teachers, in order to determine their experiences, perceptions and needs. Concepts in the transcripts were categorised into themes and sub-themes and were verified by a literature review. A central concept was identified ( of the theory-generative research design) that can be further analysed in the second section of the research. The second section of the research was based on the findings of the research and the work of Chinn and Kramer (1995) in order to develop a training model to assist teachers in implementing inclusive education. The following additional steps of model design were employed: - Step Two : Concept definition and classification - Step Three : Construction of relationship statement - Step Four : Description and evaluation of the model - Step Five : Model operationalisation After data analysis was completed, the research established that the participating teachers were not in favour of inclusive education and therefore perceived it negatively. They also viewed themselves as not suitably equipped to work in inclusive settings. They were also discontented and experienced an intense feeling of incompetence. The researcher identified the in teachers as the central concept, which served as the foundation of the design of a model for teachers with regard to inclusive education. The essential criteria of the concept were identified and linked to each other by means of relationship statements. The model was described and evaluated according to the five criteria of clarity; simplicity; generality; accessibility; and significance, as proposed by Step One revitalisation of competence Chinn and Kramer (1995). The researcher also reflected on the limitations inherent to this research study and presented guidelines and recommendations for the operationalisation of the model in practice, to guide future research and in-service training programmes.

- Description: It is clear that the concept of inclusive education implies that learners experiencing barriers to learning should, wherever possible and with suitable support, be educated with others in a regular school setting and through a regular curriculum. It is assumed that suitable facilities, resources and assistance, where needed, will be available. An adaptable curriculum that accommodates the specific learners who experience barriers to learning is also essential for inclusive education. The focus on providing equal educational opportunities for learners experiencing barriers to learning means that the traditional roles and responsibilities in education will inevitably change. Teachers have to modify their views of themselves, their teaching methods and the roles that they have to play during the implementation of inclusive education. Teachers will have to be adequately trained to effectively and confidently provide appropriate education to learners experiencing barriers to learning. The primary goal of the study is to explore the experiences, perceptions and needs of teachers regarding inclusive education. The secondary goal is to develop a training model to equip in -service teachers better for inclusive education. The research process was structured by the application of a qualitative research approach within a theory generative design, utilising five steps of theory generation in order to reach the objectives of the study. The qualitative approach was selected, as it is exploratory in nature. Founded in this exploratory research, a central concept was identified, with the aim of developing a model to assist teachers in implementing inclusive education. ABSTRACT (xvii) The research was conducted in two phases. The first section of the research comprised an exploration of the experiences, perceptions and needs of teachers regarding inclusive education. It embraced several decisions relating to data collection and analysis processes, such as defining the population and selecting the sample procedure and the data collection method, namely personal interviews with teachers, in order to determine their experiences, perceptions and needs. Concepts in the transcripts were categorised into themes and sub-themes and were verified by a literature review. A central concept was identified ( of the theory-generative research design) that can be further analysed in the second section of the research. The second section of the research was based on the findings of the research and the work of Chinn and Kramer (1995) in order to develop a training model to assist teachers in implementing inclusive education. The following additional steps of model design were employed: - Step Two : Concept definition and classification - Step Three : Construction of relationship statement - Step Four : Description and evaluation of the model - Step Five : Model operationalisation After data analysis was completed, the research established that the participating teachers were not in favour of inclusive education and therefore perceived it negatively. They also viewed themselves as not suitably equipped to work in inclusive settings. They were also discontented and experienced an intense feeling of incompetence.

- Description: History and Background: The history of statutory labour dispute resolution of South Africa dates back to 1909, when the Transvaal Disputes Prevention Act of 1909 was promulgated which applied only to the Transvaal. The Industrial Conciliation Act of 1924 established industrial councils and ad hoc conciliation boards and excluded black workers from the statutory definition of employee and this resulted in a dual industrial relations system that existed up to 1979. The history of statutory labour dispute resolution of Swaziland dates back to 1980 when the first Industrial Relations Act of 1980 was promulgated which established the first Industrial Court. Research Findings: The dispute resolution systems of South Africa and Swaziland contain both similarities and differences. Lessons for Swaziland include combining general and specific dispute resolution procedures, providing the right of a referring party to apply for condonation for late referral of a dispute, using conciliation-arbitration, making arbitration proceedings public hearings, influence of parties on the appointment of arbitrators, court adjudication, pre-dismissal arbitration, court adjudication by judges only, establishment of a constitutional court, full protection of protected strikes/ lockouts from interdicts, legalization of sympathy strikes, and removal of strikes/ lockout ballot. Lessons for South Africa include plural representation of parties at conciliation and arbitration, re-direction of some disputes by the Labour Court to the Commission for arbitration, reporting of labour disputes direct to the Head of State for determination.
