- Description: This article seeks to investigate this balance and to interrogate the difference between horror and terror in an attempt to contribute to the development of a systematic genre typology. A brief history of the genre will be given, after which the focus will fall on contemporary Horror film, paying specific attention to the relationship between violence and horror, the theme of sacrificial violence, and the transgression of ‘natural’ laws. An eclectic approach is followed, drawing from literary theory, theology, psychology, and, of course, film theory.

- Description: Levels of diabetic care in primary health care settings in South Africa have been found to be sub-optimal. Knowledge deficits and inadequate practices have been implicated in the poor quality of local diabetes care. Type 2 diabetes and hypertension are commonly associated chronic conditions hence to optimise diabetic care, tight control of blood pressure is essential. Although guidelines for the overall management of diabetes in a primary health care setting have been published (Working Group of the National Diabetes Advisory Board, 1997; Society for Endocrinology, Metabolism and Diabetes of South Africa, 2002a), adherence to these guidelines has not yet been optimised in the primary health care setting. The objectives of the study were: to design and implement an educational intervention aimed at nursing staff, based on the South African guidelines for type 2 diabetes and hypertension, at a public sector primary health care clinic; to determine the impact of the educational intervention on the level of knowledge and attitudes of the nursing staff, and on the level of diabetic and blood pressure control achieved in the patient population, and to determine the impact of the educational intervention on pharmacological management of patients. A questionnaire was used to quantitatively assess the nursing staffs’ knowledge of the management of type 2 diabetes and hypertension at a primary health care level. A qualitative evaluation of the nursing staff attitudes was obtained using focus group interviews. The educational intervention, in the form of lectures and based on national diabetes and hypertension guidelines (Working Group of the National Diabetes Advisory Board, 1997; Society for Endocrinology, Metabolism and Diabetes of South Africa, 2002a; Milne et al., 2003), was then implemented and directed at the nursing staff at a primary health care clinic. A post-intervention evaluation was performed after four months by repeating the questionnaire and focus group interviews. Comparisons between the pre- and post-intervention questionnaire and focus group interviews evaluated the impact of the educational intervention on the knowledge and attitudes of nursing staff towards the management of type 2 diabetes. Pre- and post-intervention patient data was collected from patient medical files and compared to determine if the management of diabetes and hypertension improved in the patient population after the implementation of the educational intervention. The patient population consisted of 103 patients. The educational intervention resulted in an extremely significant improvement in the level of knowledge of the nursing staff [93 correct responses (28.3 percent; n = 329 (pre-intervention)) vs 223 correct responses (67.8 percent; n = 329 (post-intervention)); p < 0.0001, Fisher’s Exact test]. The educational intervention resulted in improved attitudes of nursing staff towards the management of diabetes. Ideal random blood glucose concentrations improved significantly [16 percent; n = 100 (pre-intervention) vs 22 percent; n = 100 (post-intervention); p = 0.0003; Student t test]. The number of patients with a compromised HbA1c level (> 8 percent) decreased by 2 [51; 49.5 percent, n = 103 (pre-intervention) vs 49, 47.5 percent, n = 103 (post-intervention)] which was not a significant improvement. Ideal blood pressure control improved by one from 38 patients [36.9 percent; n = 103 (pre-intervention)] to 39 patients [37.9 percent; n = 103 (post-intervention)] which was not significant. Optimal change of pharmacological management following the referral of an uncontrolled diabetic patient was only noted for 18 patients (20.2 percent, n = 89) referred in the post-intervention phase. Clinical inertia was identified as a major limitation to the optimisation of diabetes care. Implementation of an educational intervention based on the South African diabetes and hypertension guidelines at a public sector primary health care clinic was successful in improving the knowledge levels and attitudes of nursing staff

- Description: Operating room nurses form the corner-stone of the operating room because perioperative care of the patient rests mainly in the hands of the nursing personnel. Unique challenges face nurses functioning in the stressful surgical environment where anticipation to prevent or cope with life-threatening situations is the order of the day. The operating room nurse must be knowledgeable, skilled and alert, as he/she is held accountable for all acts of commission and omission. To ensure that nurses are appropriately educated and trained and able to keep trend with the changing technology in the operating room, it is essential that learning programmes meet the minimum standards for registration as prescribed by the South African Nursing Council. Reviewing and evaluating learning programmes on a regular basis by specialist nursing educationists, are therefore essential to ensure that the standards of education and training are maintained and upgraded if required. The aim of this study is to explore and describe the various Operating Room Nursing Science Learning Programmes offered at accredited Higher Education Institutions, utilized for the education and training of the operating room nursing students in South Africa. The proposed research is based on a qualitative paradigm and the theoretical grounding is found in Bergman’s model for professional accountability (Bergman, 1982:8). A document analysis of five approved comprehensive Operating Room Nursing Science Learning Programmes from higher education institutions in South Africa (nursing colleges and universities) was carried out, together with a sixth programme, the Operating Theatre Learning Programme, as suggested by the Standard Generating Body. Requests for permission were forwarded to the management of the selected colleges or universities for inclusion of the respective programmes in the study. The researcher formulated and utilized thirty-four essential criteria derived from three documents, the first being a document entitled “Proposed Standards for Nursing and Midwifery Qualifications” submitted to the SANC and SAQA by the SGB for Nursing and Midwifery (2001-2004). The second document entitled the Public and Private Higher Education Institutions format template for criteria for the Generation and Evaluation of Qualifications and Standards within the National Qualifications Framework was also utilized (SAQA, 1430/00) and thirdly the researcher included the most relevant criteria from the list of criteria for curriculum development as indicated by the South African Nursing Council. Various tables were compiled, to reflect the findings of the document analysis according to the thirty-three criteria indicated above, to provide a clear and broad overview of the specific data in the respective six Operating Room Nursing Science Learning Programmes utilized in the study. In conclusion recommendations for a broad macro-curriculum were made to facilitate formulation of programmes in Operating Room Nursing Science relevant to the South African context.

- Description: The microstructure and physical properties of hot pressed (Hf, Ti) C have been investigated with the aim of producing a cutting tool material with similar hardness to that of WC-Co and TiC-based cermets. Sintered samples were hot pressed from HfC0.7 and TiC0.9 powders using powder metallurgical techniques and the processing cycle was optimized for this system. Ni was used as a binder in selected samples and C black was added to compensate for sub-stoichiometry and to aid in the reduction of oxides formed during milling. Microstructural analyses were performed by scanning and transmission electron microscopy (SEM and TEM) and the composition was determined from X-ray diffraction (XRD) and energy dispersive X-ray spectrometry (EDS). The physical properties measured are density and Vickers hardness, and the indentation fracture toughness was determined using the Shetty formula. The fundamental interactions between HfC, TiC and Ni during hot pressing were investigated and the results obtained used to explain the microstructure that develops in samples made from powder mixtures. The interactions studied are the inter-diffusion of HfC and TiC through the solid state, and the dissolution and re-precipitation rate of the carbides in a liquid Ni binder. EDS analysis revealed that the rate at which Ti diffuses into HfC is higher than the rate at which Hf diffuses into TiC. Upper limits to the diffusion coefficients for these processes are determined and show that solid solution carbides will form from HfC + TiC powder mixtures at 2000 ºC in 1 hour if the average powder particle size is less than 5 μm. The diffusion rates decrease with a decrease in hot pressing temperature but mass transport between the phases can be enhanced by addition of a metallic binder. TEM and EDS analysis shows that Ni wets TiC more efficiently than HfC and that the solubility of TiC in Ni is also higher than that of HfC. The grain size of the carbide phases increases with an increase in the rate at which they dissolve into and re-precipitate from the liquid binder. The crystal structure of the binder phase depends on the concentration of Ti and Hf that remain in the binder after cooling and the carbide phase in which the binder is embedded. Analysis of TEM electron diffraction patterns show that the binder phase consists of cubic solid solutions as well as intermetallic and cubic phases in which atomic ordering is observed.

- Description: This study originated from an evaluation of the performance of a commercially available high concentration point focus concentrator PV system. The effect of module design flaws was studied by using current-voltage (I-V) curves obtained from each module in the array. The position of reverse bias steps revealed the severity of mismatch in a string of series-connected cells. By understanding the effects of the various types of mismatch, power losses and damage to the solar cells resulting from hot spot formation can be minimized and several recommendations for improving the basic performance of similar systems were made. Concern over the extent and type of defect failure of the concentrator photovoltaic (CPV) cells prompted an investigation into the use of a light beam induced current (LBIC) technique to investigate the spatial distribution of defects. An overview of current and developing LBIC techniques revealed that the original standard LBIC techniques have found widespread application, and that far-reaching and important developments of the technique have taken place over the years. These developments are driven by natural progression as well as the availability of newly developed advanced measurement equipment. Several techniques such as Lock-in hermography and the use of infrared cameras have developed as complementary techniques to advanced LBIC techniques. As an accurate contactless evaluation tool that is able to image spatially distributed defects in cell material, the basis of this method seemed promising for the evaluation of concentrator cells.

- Description: Educational change in South Africa has been met with stern resistance and educators are faced with enormous difficulty in implementing new policies and curricula. Educators who have been deskilled over the years are now all of the sudden required to think ‘outside the box’ and to undergo a complete mindset change regarding the implementation of the new Further Education and Training curriculum. The new challenges educators have to cope with, heavily impacts on their day to day working conditions and subsequently their motivation. Due to the increased awareness and concern with regards to the level of educators’ motivation, this research study is based on the research question, namely how motivated educators were for the implementation of the new Further Education and Training curriculum and secondly, to explore guidelines to enhance their motivation. In an attempt to provide answers to the research problem, a qualitative research design was adopted for this research and was undertaken in two phases. In Phase 1, the data gathering consisted of semi-structured group interviews. The data was then coded into themes, sub-themes and categories and served as the basis for the interpretation of how motivated educators were for the implementation of the new Further Education and training curriculum. Four main themes emerged from the data analysis; Teachers expressed distrust in the Department of Education; Negative expectations of FET are based on the inadequate training teachers received; Teachers are de-motivated and display a low morale; Few aspects contribute to a positive attitude. Phase 2 offered recommendations, derived from the findings of Phase 1, to enhance the motivation of educators for the implementation of the new Further Education and Training curriculum. It was evident from the data analysis that educators were experiencing difficulties in coping with the heavy demand being placed on their shoulders to effectively implement the new curriculum. They displayed negative feelings towards the Department of Education who expected them to implement change within a limited time-frame. The conclusion was reached that educators are in desperate need for motivational strategies and support to enhance their emotional well-being, motivation and self-efficacy.

It was evident from the data analysis that educators were experiencing difficulties in coping with the heavy demand being placed on their shoulders to effectively implement the new curriculum. They displayed negative feelings towards the Department of Education who expected them to implement change within a limited time-frame. The conclusion was reached that educators are in desperate need for motivational strategies and support to enhance their emotional well-being, motivation and self-efficacy.

- Description: In this work, a systematic study relating the surface morphologies, electrical and structural properties of both doped and undoped InAs and InAsSb epitaxial films grown by metalorganic chemical vapour deposition (MOCVD) was undertaken. A comparative study using TBAs and AsH3 as the group V source in the growth of InAs revealed a considerable improvement, primarily in the electrical properties of InAs grown using TBAs with no significant difference in the surface morphology. InAs layers grown using TBAs, exhibited superior 77 K mobilities of up to 46 000 cm2/Vs, exceeding the best MOCVD data to date. The feasibility of tetraethyl tin (TESn) as an n-type dopant in InAs was to our knowledge investigated for the first time. The incorporation efficiency of this dopant was extensively studied as a function of substrate temperature, V/III ratio, substrate orientation and TESn flow rate. Results from this study show that the doping efficiency is temperature dependent and is not influenced by a variation of the V/III ratio or substrate orientation. Furthermore, Sn doping concentrations could be controlled over 2 orders of magnitude ranging between 2.7 x 1017 and 4.7 x 1019 cm-3 with 77 K mobilities ranging from 12 000 to 1300 cm2/Vs. The electrical properties of zinc doped InAs employing dimethyl zinc (DMZn) as the ptype dopant, were studied as a function of V/III ratio and substrate orientation. The effect of a variation of these parameters on the structural properties and surface morphology of InAs is also reported. The substrate orientation appears to have no influence on the Zn incorporation. An increase in Zn incorporation resulted in a deterioration of both the surface morphology and structural quality of the InAs layers. The incorporation efficiency of DMZn in InAsSb was studied as a function of growth temperature, V/III ratio and DMZn flow rate. A higher Zn incorporation was observed in InAsSb epitaxial layers grown at a lower temperature and V/III ratio as opposed to the layers grown at a higher temperature and V/III ratio. This study also revealed that the use of DMZn caused a dopant memory effect. A two-layer model proposed by Nedoluha and Koch (1952) was used to simulate the Hall measurements of Zn doped InAs and InAsSb in order to correct the shortcomings of conventional Hall measurements in determining the electrical properties exhibited by these materials.

- Description: One of the most critical assets in most organisations is information. It is often described as the lifeblood of an organisation. For this reason, it is vital that this asset is protected through sound information security practices. However, the incorrect and indifferent behaviour of employees often leads to information assets becoming vulnerable. Incorrect employee behaviour could have an extremely negative impact on the protection of information. An information security solution should be a fundamental component in most organisations. It is, however, possible for an organisation to have the most comprehensive physical and technical information security controls in place, but the operational controls, and associated employee behaviour, have not received much consideration. Therefore, the issue of employee behaviour must be addressed in an organisation to assist in ensuring the protection of information assets. The corporate culture of an organisation is largely responsible for the actions and behaviour of employees. Therefore, to address operational information security controls, the corporate culture of an organisation should be considered. To ensure the integration of information security into the corporate culture of an organisation, the protection of information should become part of the way the employees conduct their everyday tasks – from senior management, right throughout the entire organisation. Therefore, information security should become an integral component of the corporate culture of the organisation. To address the integration of information security into the corporate culture of an organisation, a model was developed which depicted the learning stages and modes of knowledge creation necessary to transform the corporate culture into one that is information security aware.

- Description: The project was concerned with studying the capability of a micellar-enhanced ultrafiltration system (MEUF) to remove platinum group metal ions namely Pt (lV) and Pd (ll) chloro anions from aqueous industrial waste effluents. South Africa has the world’s largest reserves of platinum group metals (PGMs) and other valuable metals such as manganese, chrome ores, titanium minerals etc. which are required for new automotive and other technologies, including fuel cells, catalytic converters and lighter components. The consistent loss with the industrial waste stream and the toxicological effects of these precious metals led to the need to develop new and effective methods to recover them from industrial waste effluents. With such a wide variety of fields where these PGMs are used and the failure of the traditional techniques namely sedimentation, fermentation etc. to effectively reduce or recover these highly toxic and precious metal ions prior to discharging industrial waste effluents, it is necessary to explore other techniques such as membrane technology that can be used to recover these valuable species from industrial waste streams. The present study involved the use of a cationic surfactant, viz cetylpyridinium chloride, which was introduced into an aqueous solution containing palladium and platinum metal anions. The surfactant forms charged micelles above a certain critical concentration value. The metal anions adsorb onto the available oppositely charged sites on the micelle surfaces and are then able to be retained by a suitable membrane. Hollow fibre ultrafiltration membranes with the MWCO of +/- 10 kD and +/-30nm pore size were used as a filter component in this study. For this MEUF system to be effective, it was vital that the anionic metal ion species adsorbed sufficiently onto the available oppositely charged sites of the micelles and that the micelles were retained efficiently by the membrane. Results obtained during the investigation made it possible to make certain predictions about the micellisation process. It was also found that, it was not only the metal ion: surfactant (M:S) ratio that was critical, but the presence of other electrolytes in the aqueous stream proved to have a huge impact on the capability of the MEUF system. Findings of this research study showed that the MEUF system using cetylpyridinium chloride (CPC) can be used to recover or retain Pt (lV) and Pd (ll) anions from industrial waste effluents. It was also found that PtCl6 2-, due to its greater adsorption capabilities onto the micelle surface than PdCl4 2- or PdCl3(H2O)-, was preferentially retained in neutral medium. This may be exploited as a possible means of separating the two metal ions. The developed system offers the following advantages over some traditional and current methods: simplified unit operation line flow process, smaller amounts of chemical usage and no solid toxic sludge to be disposed of. Applications of this work could be of vital importance in catalytic converter recycling, especially in Port Elizabeth where extensive automobile parts manufacturing occurs.

- Description: The purpose of this study was to study marital turnarounds by focusing on the exploration of the reasons for couples remarrying each other. A comprehensive approach based on human ecology provided a framework for exploring the reasons for marital turnarounds ranging from micro to macro level factors. Data was collected through six semi-structured interviews, with two African marital turnaround couples from the Nelson Mandela Metropole. Data analysis was carried out systematically through a stepwise process. Data verification and trustworthiness was also performed. Five major themes emerged from the data analysis of the interviews as follows: Culture and religious influences, individual influences, personal growth, family influences and the influence of friends. Culture and religion emerged as powerful theme in shaping decisions about marital turnaround. An important sub-theme was that, in a culture that continues to value marriage as a permanent commitment, spouses internalised the social and religious norm of marriage as a permanent commitment.

- Description: This treatise begins with a discussion of different clauses of the Bill of Rights in the South African Constitution and the land reform policies of the South African government. The inequality and injustice caused by decades of apartheid land law forms the background of the land reform programme. The treatise addresses the consequences of this legacy on the implementation of the South African Constitution including the right to property. The discussion includes the three key elements of the land reform programme namely restitution, redistribution and tenure reform. The content of this treatise ranges over these three elements of land reform, applying constitutional issues to the relevant case law, The balancing and the reconciliation of rights and interest between the individual and the public in a just manner will be the barometer. The conclusion shows that the Constitution both protects existing rights and authorises the promotion of land reform within the framework of Section 25 of the Constitution, and that every aspect of the property clause has to be regarded as part of a constitional effort in balancing individual interest and public interest in terms of a constitutional order. It is my sincere hope that this treatise will contribute toward the achievement of equity, stability and by the values of an open and democratic society based on human dignity, freedom and human rights.

- Description: This study focuses on the role of media portrayal and coverage in serial killing. The first objective of the study is to develop a conceptual structure that aids in the understanding of the cyclical relationship between media, serial killer, and audience. The media acts as a catalyst in this relationship, providing the stage on which serial killer and audience form a fatal relationship in which celebrity status forms the ultimate motivation. Media sensationalism of serial killing and the extreme glamorization in fictional representations has obviously negative consequences. In developing such a structure I hope to demonstrate that there is an alternative to the sensationalizing and glamorizing of serial killers in the media. This alternative will take the form education and a more documentary-style approach to films about serial murder. The study focuses mainly on developing a theoretical framework that emphasizes each of the three elements of the cyclical relationship mentioned above separately. The second chapter is devoted to the media and its role. The third chapter focuses on serial killers and the motivations involved. The fourth chapter deals with the audience attracted to serial killing as a source of identification. A number of thinkers’ work is used in coming to grips with this relationship, including both American and South African authors. The fifth and final chapter takes into consideration the moment of application by addressing the South African situation. I conclude by discussing the repercussions of media glamorization and possible documentary-style alternatives.

- Description: Acquired Immunodeficiency Syndrome (AIDS) is a human disease caused by the human immunodeficiency virus type 1 (HIV-1) and it is one of the biggest social, economic and health challenges in the world. The Joint United Nations Programme on HIV/AIDS (UNAIDS) and World Health Organization (WHO) estimated that between 33.4 to 46.0 million people around the world were living with HIV/AIDS in December 2005 and the highest estimates are in the Sub-Saharan Africa (around 25 million). In more developed countries a combined antiretroviral therapy called highly active antiretroviral therapy (HAART) is used, which results in reduced progression to AIDS in most patients. Despite the beneficial effects of HAART, significant side effects are experienced by treated patients. In addition, most infected people live in countries where the treatment is very expensive or, in many cases, not available at all. These people therefore rely on medicinal plants for health care. In this study, aqueous extracts from Sutherlandia frutescens and Lobostemon trigonus were screened for potential anti-HIV activities in a series of in vitro enzymatic assays, including reverse transcriptase, HIV-1 protease and glycohydrolases. Two extracts of Sutherlandia leaves (SFL-1 and SFL-2) were prepared that inhibited HIV reverse transcriptase and a Lobostemon leaf extract (LTL) was shown to also inhibit this enzyme. All extracts were assayed at 1.25mg/ml. Tannin content was determined for all active extracts using a tannic acid assay. SFL-1 and SFL-2 were found to contain about 6 percent and 7 percent tannins, respectively, and LTL contained 31% tannins by weight. Tannins were removed using polyamide columns and three fractions were collected for each. The extracts were also fractionated with Sephadex G-25, Amberlite IR 120 and Dowex 1-X8 as size exclusion, cation exchange and anion exchange, respectively. Extracts were also fractionated by preparative thin layer chromatography where two compounds were separated from S. frutescens extract with high activity against reverse transcriptase while showing insignificant inhibition towards other enzymes tested. SFL-BFW-10 and SFL-WEF-7 inhibited reverse transcriptase by almost 100 percent and the IC50 values calculated for these compounds were 0.34 and 0.23mg/ml, respectively. Cytotoxicity of these compounds was evaluated on Chang liver cells and peripheral blood mononuclear cells (PBMCs). None of these compounds showed any significant inhibition of cell proliferation. The purity of these compounds could not be confirmed because there was insufficient material to use in the techniques required to show purity and identification. Therefore, TLC was used to determine the nature of these compounds. SFL-BFW-10 was identified as an organic acid and SFL-WEF-7 was identified as flavonoid.

- Description: The IL’s used in this study were either synthesized or commercially available. Preparation of the IL’s involved 2 step processes: firstly the heating of distilled 1-methylimidazole with distilled 1-chlorobutane under reflux to obtain 1-butyl-3- methylimidazolium chloride; secondly, the metathesis reaction of sodium tetrafluoroborate with 1-butyl-3-methylimidazolium chloride to obtain 1-butyl-3- methylimidazolium tetrafluoroborate. The addition of sodium tetrafluoroborate, sodium hexafluorophosphate and lithium trifluoromethane sulfonamide with 1-butyl-3-methylimidazolium chloride produced good yields of 1-butyl-3-methylimidazolium tetrafluoroborate, 1-butyl-3-methylimidazolium hexafluorophosphate and 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide respectively. The IL’s are hygroscopic and must be stored under a nitrogen atmosphere. The IL’s were analyzed using 1H and 13C NMR analysis with CDCl3 as solvent. The physical and chemical properties of these IL’s were compared to commercial products. The physical and chemical properties compared well to reference values from the literature. The physical properties measured include the density, conductivity and electrochemical window. The electrochemical window is dependant primarily on the resistance of the cation to reduction and the resistance of the anion to oxidation. The electrochemical windows of the IL’s were very similar to the reference windows obtained from literature and it can be seen that some IL’s have a slightly lower window which can be due to water present. Water content in the IL’s was determined with the use of a Karl Fischer titrator, with Hydranal 5 Composite as titrant and HPLC grade methanol as the base. The concentration of halide in the IL’s was determined with a Perkin-Elmer ICP-MS.

- Description: This investigation attempts to examine the influences of validation on pharmaceutical processes especially at a new manufacturing facility that has to meet international requirements, and fulfil a cost effective business strategy. At Aspen Pharmacare, a pharmaceutical organisation, there are two manufacturing facilities situated adjacent to each other, one new and one old. The new facility creates ideal opportunities to supply products to local and international markets. The investigation compares legal requirements from local and international regulatory authorities. Validation and qualification practices as well as the problems encountered during the different phases are discussed. Particular attention is given to the validation approach at the new Aspen facility. Problems and proposed solutions relating to the design review, installation, operational, and performance qualification are discussed. Validation of analytical methods for cleaning analysis, cleaning validation of equipment, and optimisation of some tablet manufacturing processes are described. Statistical evaluations of analytical results are included to find the optimum conditions for integrating new personnel with new processes and equipment. A business model reviews the cost of non-conformances of the enalapril maleate 10 mg tablets manufactured at the two manufacturing facilities. Finally the dissertation proves that validation is not only a regulatory requirement but that it also provides benefits such as adding value to the business, and ultimately reducing the cost of medicines.

- 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.

- Description: In today’s computing environment, awareness programmes play a much more important role in organizations’ complete information security programmes. Information security awareness programmes are there to change behaviour or reinforce good security practices, and provide a baseline of security knowledge for all information users. Security awareness is a learning process, which changes individual and organizational attitudes and perceptions so that the importance of security and the adverse consequences of its failure are realized. Therefore, with proper awareness, employees become the most effective layer in an organization’s security defence. With the important role that these awareness programmes play in organizations’ complete information security programmes, it is a must that all organizations that are serious about information security must implement it. But though awareness programmes have become increasing important, the level of awareness in most organizations is still low. It seems that the current approach of developing these programmes does not satisfy the needs of most organizations. Therefore, another approach, which tries to meet the needs of most organizations, is proposed in this project as part of the solution of raising the level of awareness programmes in organizations.

- Description: Pharmaceutical advertising involves the advertising of medicines, medical devices, and healthcare services. A review of available international literature indicates the belief that pharmaceutical advertisements negatively affect healthcare decisions made by consumers. Very little research has been conducted to determine how consumers in South Africa (SA) are affected by pharmaceutical advertisements. This study aimed to determine how consumers in the Nelson Mandela Metropole (NMM) perceive pharmaceutical advertisements. More specific objectives included the investigation of legislation in SA employed in pharmaceutical advertisements, the interpretation and misinterpretation of the advertisements, and the identification of problematic areas in this form of advertising. South African legislation applied to pharmaceutical advertisements was investigated by means of a literature review. A qualitative research design was also used to achieve the aim and objectives. This included a focus group consisting of six randomly selected participants in the NMM. A consumer survey, consisting of a 100 consumers obtained from 10 randomly selected community pharmacies within the NMM, supported the findings of the qualitative techniques. The themes identified in the focus group were incorporated into a questionnaire used in the consumer survey. Three randomly selected pharmaceutical advertisements were also decoded to interpret the components employed in each. The results determined that pharmaceutical advertising is a marketing tool that incorporates various emotional and psychological techniques to persuade consumers. It was also evident that consumers can misinterpret pharmaceutical advertisements. Various legal and ethical problems were identified in pharmaceutical advertisements. These results showed that pharmaceutical advertisements have the possibility of negatively affecting consumers’ healthcare decisions and warrants further investigation.
