- Description: The aim of this study was to develop a standardised set of Environmental-Health work methods and procedures, with the purpose of contributing to the effective surveillance and control of Cholera in the KwaZulu-Natal province, South Africa. The researcher followed a qualitative research design, which was explorative, descriptive, inductive and deductive by nature. The methods of data collection were documentary research and focus-group interviews. A documentary research approach was employed as the primary method of data collection for the study. The researcher has used semi-structured questions to obtain relevant information from the participants in the focus groups. The purpose of using semi-structured questions in the focus groups was to draw on their knowledge and experience of communicable disease surveillance and control in relation to Cholera, as well as to ascertain their views on the role of the Environmental-Health Practitioners in the Communicable - Disease Outbreak- Response Teams at the three different spheres of government. The process of qualitative data analysis was followed. This was based on data reduction and interpretation; and it was conducted as an activity simultaneously with data collection, data interpretation (coding) and narrative writing. The information obtained from the analysed data assisted in the development of the environmentalhealth work methods and procedures for the surveillance and control of Cholera in the KwaZulu-Natal province, South Africa. In this study, firstly, the epidemiology of Cholera was described and analysed against the background of its manifestation in South Africa. Secondly, the national health care system, with specific reference to the place and role of environmental health practitioners at national, provincial and municipal spheres – in relation to Cholera surveillance and control – was analysed. Thirdly, the relevant research that has been done globally has been analysed against the background of the findings of the above, together with work methods and procedures to be used by environmental-health practitioners during the surveillance and control of Cholera in the KwaZulu-Natal Province, South Africa. These include, inter alia: Work methods and procedures for Cholera case investigation; Work methods and procedures for sanitary investigations; and Work methods and procedures for identifying the sources of contamination in environmental waters. Finally, the conclusion and limitations was presented, and appropriate recommendations were made. These include: he need to educate all role - players, on the recent developments in the identification of Vibrio cholerae from environmental surface waters; Communication systems should be developed that allow the Director: Environmental Health to communicate urgent environmental health information directly to the Minister of Health; he training of environmental-health practitioners on detailed work methods and procedures for the surveillance and control of Cholera; and the existing national Cholera control guidelines need to be updated to include relevant environmental health situations when emergencies arise.

- Description: It was the objective of this project to provide a glass cleaner formulation for a wet wipe application with cleaning and anti-fogging properties. This glass cleaner formulation was developed for automotive glass i.e. interior of windscreens. This formulation relates to a glass cleaner with a composition comprising of: (a) a blend of amphoteric surfactants; (b) a solvent system with a combination of glycol ethers; and (c) an aqueous solvent system. This glass formulation must provide good cleaning properties while also providing good wetting and sheeting properties to assist with anti-fogging properties. The objectives were obtained using 2 specific approaches: The first was by using a blend of 2 amphoteric surfactants in an alkaline medium, allowing the glass surface to become more hydrophilic which will also assist with reduction of surface tension on the glass surface. The second was by using the glycol ethers that have good coupling properties and surface tension reducing properties. The formulation was evaluated using commercial standard test methods as per the industry. A predictive model was successfully obtained for each of the five criteria that were evaluated using the 25 formulations derived from the statistical design. There were variables and variable interactions that were antagonistic for some of the criteria which were found to be synergistic for others. To achieve satisfactory cleaning, the fogging rating had to be compromised.

- Description: Information plays a vast contributing role to all resources within an organisation. Organisations should recognise the importance of information and implement information security controls to protect their information as this will ensure that the organisation‟s information retains its confidentiality, integrity and availability. Information security controls, which are the means of managing information risks, rely heavily on the user‟s knowledge regarding the use of these controls for their effectiveness, and as such, users should be educated in order to maximise effectiveness of these controls. Current information security educational programmes are created without necessarily taking into account the target audience, who comprises of all employees, stakeholders, suppliers, third parties, customers or other external parties or third party that requires access to the organisation‟s information. This results in programmes that are not linguistically appropriate; or that present knowledge at an inappropriate level for the target audience. This could leave users bored or confused, without successfully changing their behaviour or improving knowledge. This dissertation identifies a baseline for information security knowledge targeted at end users. This was done by means of a Delphi Study, where a profile of “generic” end users comprised of information security topics and concepts were rated by experts from the field of information security education. This resulted in the elimination of inappropriate topics and concepts and retaining the relevant and appropriate aspects. This baseline for information security knowledge can be characterised as a minimum standard that everybody should be educated on as an introductory or refresher course. This can also serve as the foundation phase to educate end users with knowledge of the basic topics and concepts to enable them to fulfil their responsibilities in order to protect information. If needed, topics and concepts could be added to the baseline for information security knowledge for specialised target audiences (e.g. specialised End Users, ICT Staff or Top Management).

- Description: If you do not own the latest technology today it is thought that you are left behind in this technology driven age. More businesses use Self- Service channels to accommodate the increasing demands of customers. It has been said that the use of self-service channels can reduce input costs, increase efficiency and improve customer service. Unfortunately, many customers are left unsatisfied because retail banks are moving away from the human interaction when visiting a branch or advise customers to use their self-service channels, sometimes without any assistance. This causes customers to move banks, complain and in so doing reduce profits and customer relationships with their banks.This research’s main objective was to determine the impact of customer relationship management on retail banks that make use of self-service channels. A theoretical overview of self-service channels and customer relationship management was given. Advantages and disadvantages of each option were explored. The researcher wanted to explore the relation between customers using self-service channels and the assistance and protection provided by retail banks. The customer experience questionnaire used in this research asked retail banking customers from the South African population to determine how customers perceive and experience their banks’ self-service channels and customer service. Many questions relating to their needs and wants with regards to banking have been explored. The results show that most customers are satisfied with their banks in general but do feel that the banks can improve their customer service and assistance with regards to using self-service channels like ATM’s, online and telephone banking and E-Wallet. It has concluded that most customers choose their banks based on advertisements and other media, not customer service, product range or word-of-mouth. The general perception is that customers say that their bank charges do justify the customer service received.

- Description: The main objective of the study is to explore how cloth, the body and movement are able to communicate possible symbolic meaning in Loïe Fuller’s Serpentine Dance film and Moderat’s Rusty Nails music video. The study further attempts to establish the characteristics of fashion film to include cloth, the body and movement and provide a methodology that locates fashion film as a sign system using a visual semiotic analysis framework. The films were then compared and contrasted to determine similarities and differences in their use of cloth, the body and movement. The findings from the film analysis suggest that cloth, the body and movement communicate symbolic meaning in the films based on their associated meanings that are generated both inside and outside the film context. By focussing on cloth, the body and movement as primary communicators (rather than secondary or supporting communicators) in film, new meanings can be interpreted from their interrelationship. The results inform new ways for fashion designers and fashion filmmakers to engage with cloth, the body and movement in fashion film.

- Description: It has been found that many small, medium and micro-sized enterprises (SMMEs) do not comply with sound information security governance principles, specifically the principles involved in drafting information security policies and monitoring compliance, mainly as a result of restricted resources and expertise. Research suggests that this problem occurs worldwide and that the impact it has on SMMEs is great. The problem is further compounded by the fact that, in our modern-day information technology environment, many larger organisations are providing SMMEs with access to their networks. This results not only in SMMEs being exposed to security risks, but the larger organisations as well. In previous research an information security management framework and toolbox was developed to assist SMMEs in drafting information security policies. Although this research was of some help to SMMEs, further research has shown that an even greater problem exists with the governance of information security as a result of the advancements that have been identified in information security literature. The aim of this dissertation is therefore to establish an information security governance framework that requires minimal effort and little expertise to alleviate governance problems. It is believed that such a framework would be useful for SMMEs and would result in the improved implementation of information security governance.

- Description: Information and Communication Technology (ICT) has become an integral part of almost every individual’s life. Although ICT, particularly the Internet, might offer numerous opportunities, individuals should also be aware of the associated risks. Especially with the younger generations who can be seen as being the most vulnerable to online dangers as they are becoming more involved in online activities. Children are utilizing new technologies from an early age and should know how to keep themselves and others safe whilst accessing the Internet. However, most of them do not have the required knowledge and expertise to protect themselves. This is because, under most circumstances, the parents do not understand their children’s online behaviours and activities and are, therefore, unable to teach their children how to utilize it safe and responsibly. A school can be seen as the perfect place to teach children safe online behaviours. However, there is currently a definite lack of e-Safety in South African schools, because no e-Safety policies are in place and there is little or nothing in curricula with regards to e-Safety. This can lead to additional concerns. The primary objective of this research study is, therefore, to develop, motivate and verify a framework that might contribute towards the development of an e-Safety culture. This e-Safety culture should allow individuals to adapt their behavior towards the secure utilization of ICT. However, for the purpose of this research study, the focus will primarily be on learners from primary and secondary schools.

- Description: The aim of this study was to establish whether samples of South African-mined clinoptilolite could be used to remove selected metal cations from aqueous solution. The clinoptilolite samples supplied, (by Pratley SA) were in four different particle sizes. Batch study results revealed a decrease in the initial metal concentration in samples that were in contact with clinoptilolite. The finer particle size clinoptilolite had a greater capacity to remove metal cations from aqueous solution. However, ion-exchange results from atomic absorption analysis showed that the larger particle sizes, removed more magnesium ions. Magnesium was the only ion investigated in this study that was present as an exchangeable ion in the Pratley clinoptilolite chemical formula, (MgCaNa2K2)2.5(AlO2)7(SiO2)30.21H2O. Results from the ion-exchange studies showed that the decreasing order of percentage metal removal at pH 3.00 was as follows: Pb > Ni > Cu > Fe > Mg. The mass of metal ions that accumulated on one gram of clinoptilolite as determined from the isotherms was calculated to be 6.16 mg/g for lead and 0.74 mg/g for copper. Data from the lead equilibrium studies were fitted into Langmuir and Freundlich equations and linear regression was used to calculate linearity coefficients for the isotherms. The results showed that the removal of lead ions by clinoptilolite is complex as both monolayer and multilayer adsorption occurs on a heterogeneous surface.

- Description: Businesses are continuously exposed to a changing business environment which may either exert positive or negative influences on profitability. The banking industry, in particular, is highly competitive and bank failures can have significant consequences for customers. Commercial banks, therefore, have a responsibility to protect their customers by implementing sound risk management strategies. In light of the recent financial crises (since 2007), risk management has once again become a popular topic of discussion since adequate risk management should have prevented or minimised the impact of the risks faced by failed banks. The primary objective of this study was to develop a framework that could be used by South African commercial banks to investigate risk management. Qualitative research was conducted in this regard. From this, findings and recommendations were derived in order to provide banks with a tool by which they could assess their exposure to risk. Various journals, websites, newspapers, bank reports and textbooks were consulted in support of the literature. The literature provided background information on the history and development of the risk management process. Considerable attention was given to the categories of risk that an adequate risk management framework should address. Furthermore, the current models used to manage risk in commercial bank were provided, as well as the specific reasons for bank failures. The main findings of this study were the identification of the most significant reasons for banking failures. These were identified as capital inadequacy, credit risk due to non-performing loans and a lack of banking supervision. In addition to these reasons, several other contributing principles were identified as important factors to be included in a risk management framework. A risk management framework was thus constructed in Table 5.1 based on the literature regarding global banking failures and the relevant conclusions made by the researcher.

- Description: Businesses are continuously exposed to a changing business environment which may either exert positive or negative influences on profitability. The banking industry, in particular, is highly competitive and bank failures can have significant consequences for customers. Commercial banks, therefore, have a responsibility to protect their customers by implementing sound risk management strategies. In light of the recent financial crises (since 2007), risk management has once again become a popular topic of discussion since adequate risk management should have prevented or minimised the impact of the risks faced by failed banks. The primary objective of this study was to develop a framework that could be used by South African commercial banks to investigate risk management. Qualitative research was conducted in this regard. From this, findings and recommendations were derived in order to provide banks with a tool by which they could assess their exposure to risk. Various journals, websites, newspapers, bank reports and textbooks were consulted in support of the literature. The literature provided background information on the history and development of the risk management process. Considerable attention was given to the categories of risk that an adequate risk management framework should address.

- Description: This dissertation involves the experimental investigation of commercially pure titanium (CP Ti) which was subjected to laser forming and mechanical forming processes. Commercially pure titanium grade 2 was formed to a radius of curvature of approximately 120 mm using three forming procedures, i.e. i) laser forming; ii) mechanical forming (stretched forming) and iii) a combined forming process (laser-mechanical forming). Fatigue testing revealed, for all the forming processes, that samples produced by laser forming performed the best at high load settings. However, mechanically formed specimens performed the best at low load settings, whereas the laser-mechanical process resulted in midway performance between laser and mechanical processing. Considering microstructure vs fatigue; impact vs fatigue; and residual stress vs fatigue; at high load settings it is evident that the microstructure is the dominant contributor to crack initiation and growth. Crack morphology of fatigue samples revealed that secondary cracks (parallel to main crack front) followed the grain boundaries of the Widmanstätten microstructure, whereas irregular secondary cracks grew parallel and through the twinning planes and along the grain boundaries of the equiaxed microstructure. Laser forming resulted in microstructural changes from equiaxed grains to a Widmanstätten structure due to fast cooling rates. Excessive twinning is developed within the equiaxed microstructure after the mechanical forming procedure. This is due to cold working / strain hardening. The combined process shows a combination of equiaxed grains and Widmanstätten microstructure. Residual stress relieved for all forming processes revealed an increase in the magnitude of the residual stress compared to the parent plate and that the maximum values were obtained at the inner radius of curvature (i.e. 118.4 mm). Laser forming revealed the highest values in residual stress whereas the other two processes i.e. mechanical and laser-mechanical forming exhibited an increase midway between the parent plate and laser forming. The second most influential factor with regards to fatigue was the magnitude of the residual stress, especially at medium to low load settings. When considering theoretical models to predict fatigue life it was found that the Goodman model showed the closest relation to the actual fatigue data when considering the entire theoretical curve. Vickers microhardness profiling was applied to the thickness of the samples for the parent plate and all forming processes. No significant hardening occurred due to the forming processes and differences in hardness were considered negligible. Charpy impact testing revealed that the laser formed specimens exhibited the most brittle behaviour when compared to the parent plate results. Mechanical formed specimens showed a slight increase in brittleness compared to parent plate whereas the combined process yielded results midway between the laser and mechanically formed specimens. Mathematical equations are formulated and presented for predicting the fatigue life of CP Ti grade 2 for the parent plate and the three forming processes. This study proved that the laser forming process can be successfully used as a production stage in the forming of CP Ti grade 2.

- Description: Information is a vitally important asset to organizations and the information should be protected to sustain the value it provides to the organization. Information is transferred via different mediums in these organizations. An example would be Terrestrial Trunked Radio or TETRA, which is utilized within organizations to provide a technically very secure form of digital radio communication. TETRA is a communications technology that is currently being successfully used throughout the world for secure, reliable and robust critical communication. TETRA is used by Public Safety and Security (PSS) and transportation sectors, amongst others. PSS includes police officers, fire marshals and emergency medical units who require protected and accurate information that could influence decisions that could make difference between life and death. The TETRA educational programme offered by the TETRA Academy at the Nelson Mandela Metropolitan University (NMMU), educates TETRA users in various aspects of the TETRA standard. TETRA is viewed as a technically very secure communication standard, as it utilizes security features such as mutual authentication, air interface encryption, end-to-end encryption, jamming detection and ambience listening, amongst other security techniques to ensure that the information traversing through the network is kept secure. The TETRA educational programme material includes many physical and technical controls to assist TETRA users in protecting information. However, to what extent does the TETRA educational programme address operational controls? Operational controls address what is often referred to as the weakest link in information security – human behavioural issues. Humans can be exploited through human manipulation attacks, which include social engineering and bribery. Therefore, this study argues towards adapting the TETRA educational programme offered at the NMMU to address these human behavioural issues.

- Description: Since the deregulation of Voice over Internet Protocol (VoIP) in 2005, many South African organizations are now attempting to leverage its cost saving and competitive values. However, it has been recently cited that VoIP is one of the greatest new risks to organizations and this risk is cited to increase Information Security insurance premiums in the near future. Due to the dynamic nature of the VoIP technology, regulatory and legislative concerns such as lawful interception of communications and privacy may also contribute to business risk. In order to leverage value from the VoIP implementation, an organization should implement the technology with knowledge of the potential risk of civil liability. This is further highlighted by the King III Report which indicates that the Directors of an organization should be ultimately responsible for Corporate Governance and, therefore, IT Governance and Information Security Governance. The report goes further to say that any newly implemented technology, such as VoIP, should comply with all South African legislation and regulations. This responsibility encourages the practice of both due care and due diligence. However, recent trends exercised by Information Security professionals, responsible for drafting Information Security policies and related procedures, often neglect the regulatory requirements and choose to only implement international best practices with no consideration of the risk of civil liability. Although these best practice frameworks may inadvertently comply with existing local legislation, a chance of an oversight is possible. Oversights may not only result in criminal sanctions, but also civil action due to losses or damages suffered. With regard to implementing VoIP, good Corporate Governance could potentially be ensured through the use of both identified regulations and relevant international best practices. This dissertation aims to aid organizations in avoiding or at least mitigating the risk of civil liability to better leverage VoIP’s value, through good Corporate Governance practices. This should aid in the exercise of due care and due diligence when implementing VoIP as a means of conducting business communication.

- Description: The rate of obesity has risen dramatically over recent years and is an epidemic in many countries. School pupils and university students are no exception to this. The negative effects physically, mentally and emotionally of being overweight are detrimental to one’s quality of life. It is therefore critical to encourage pupils and students to participate in physical activity. Formalised sport is a key component of encouraging physical activity. The habits learnt in childhood and early adulthood are often carried through for the rest of one’s life. The benefits of participating in sport need to be promoted extensively to the students, as research has shown students that participate in sport are not only healthier but achieve better academic results. This study examined the constraints to students’ participation in formalised sport. The empirical data was collected by means of a survey, using self-administered questionnaires distributed to students on the three Summerstrand campuses at the Nelson Mandela Metropolitan University in Port Elizabeth. Two hundred and eighty three usable questionnaires were received. Time and scheduling was found to be the most constraining factor to participation in sport. I am too busy with my university studies attracted the highest mean score of all the items on the questionnaire. It is recommended that: • sport organisers at NMMU emphasise to the students the benefits of regular participation in physical activity; • the effectiveness of the current NMMU sport programmes and accessibility be further investigated as only 18 per cent of the students in 2011 were participating in sport programmes at NMMU; • time management skills be taught to the NMMU students as the Time and scheduling constraint was the most profound constraint to participation in formalised sport; • NMMU academic staff work more closely with the staff at the University Sport Bureau to promote regular sport participation and to disseminate sport related information that could promote being more actively involved in sport; and • relevant introductory sport programmes and more internal leagues be offered, that gently introduce various sport codes to the students.

- Description: The human environment is under serious threat as natural resources such as air, water and forests are being overused. Worldwide, people have become more aware of the threatening situation and consequently many more individuals are showing concern for the environment. Often this concern is not displayed in consumers’ purchasing behaviour, as consumers who claim to be concerned about the environment are not necessarily consuming or showing a preference for environmentally–friendly products. This study examined two sets of variables, namely, person related and marketing related factors, and determined the extent to which these factors influence consumers’ behaviour when buying environmentallyfriendly products. The empirical data was collected by means of a survey, using self-administered questionnaires distributed to adult employed consumers residing in Port Elizabeth. Two hundred usable questionnaires were received. Three person related factors, namely, norms, environmental concern and environmental knowledge, and four marketing related factors, namely, price, product, place and promotion - were found to influence respondents’ behaviour when purchasing environmentally-friendly products. Environmental concern explained the largest portion of variation in purchase behaviour, while promotion explained the smallest portion of variation. Significant differences in the influence of age were found for norms, nvironmental concern, environmental knowledge and price. It is recommended that suppliers of environmentally-friendly products should ensure that these products are located at outlets which are convenient to consumers; more should be done by the relevant stakeholders to increase environmental knowledge and educate South Africans about the benefits of leading a more environmentally-friendly lifestyle; marketers find more innovative methods to convince consumers to act on their environmental concern; further attempts be made to minimise the price difference between environmentally-friendly products and traditional products; marketers should pay more attention to advertisements promoting environmentally-friendly products to ensure that these appeal to their target markets; and the performance of environmentally-friendly products should be on a par with the performance of traditional products.

- Description: This study presents an investigation into the process of constructing an autobiographical self within the genre of the autobiographical picture narrative, and explores this process both in terms of a theoretical study of this concept as well as an interpretation of a number of photographs. The interpretation entails a reading of selected autobiographical picture narratives by the artist-photographers Maggie Taylor and Lori Nix by means of a method derived from visual social semiotics. Specifically, the semiotic reading focuses on Taylor and Nix’s photographs Twilight swim (2004) and Ice Storm (1999), respectively, after which the researcher’s own autobiographical photograph entitled Fennel and coriander is read by means of the same methodological approach. The semiotic reading is guided by five salient characteristics of the autobiographical picture narrative, namely fabrication and reality, autobiographical memory, socio-cultural relevance, commonalities in female narration and narrative function. Harrison’s (2003) visual social semiotic framework (which reflects the work of social semioticians Kress and Van Leeuwen, 2002) was augmented in light of the five salient characteristics in order to construct an appropriate methodological framework. A comparative reading of the works by Taylor, Nix and the researcher reveals that although each of the artistphotographers followed a peculiar and unique approach in constructing the autobiographical picture narrative, parallels can be established in terms of various central concepts, as is evident from the semiotic reading. In particular, the role of memory and the interpretation of autobiographical elements emerged as common denominators. The process of constructing an autobiographical memory therefore provides the narrator-photographer with the options of escaping into and not from memory, thus allowing for unique possibilities in terms of interpretation, fantasy and construction.

A comparison will then be made between these liquidity ratios. The second objective is to illustrate that cash flow ratios are a better indication of liquidity of an entity than the traditional ratios. The traditional and cash flow ratios will illustrate the position of liquidity with information utilised from the various bankrupt companies’ financial statements, including the statement of financial position and statement of cash flows. Four years’ financial statement data will be used to illustrate the deteriorating liquidity positions of the companies.

- Description: The activity-based costing (ABC) system is a cost allocation technique which appears to have many benefits over the traditional costing systems. However, companies that have attempted to implement ABC have encountered various difficulties. Thus, there is a need to investigate the problems faced by companies while implementing ABC. The main objective of this study was to find solutions to overcome the problems encountered by South African companies during the implementation of an activity-based costing system.

- Description: Small and Medium Enterprises (SMEs) significantly contribute to the growth of the economy and the employment sector. However, it is indicated that SMEs lack access to the financial products and services that are critical to their growth. Therefore, the primary objective of this study was to investigate the difficulties experienced by small businesses in accessing finance. An online questionnaire survey was considered an appropriate measurement method for this study. The targeted population of the study included all small businesses operating in the Nelson Mandela Bay Metropole. Thus, some 208 companies were identified as part of the study sampling frame. A total number of 66 questionnaires were returned out of the 208 targeted companies - giving a response rate of 29 percent. The quantitative data were processed using a STATISTICA program, leading to appropriate descriptive statistical analyses, including frequencies, means, medians and standard deviations. In order to obtain a better understanding of the difficulties experienced by small businesses in accessing finance, hypotheses were also formulated and a t-test was used to establish the statistical significance of certain demographic variables and company characteristics regarding the problems experienced by small businesses in accessing finance. The results of the empirical study revealed that the major difficulties faced by small businesses in their access to finance were the lack of collateral and security, the high cost of borrowing interest and the delay in feedback from the financial institutions. Further, by testing the hypotheses, it was also revealed that the ethnic group of the applicant, the total years of business experience of the applicant and the annual turnover of the business have an impact on the access to finance. Based on the relevant literature study and the empirical results, recommendations were made in order to address the identified problems. However, the unavailability of an exhaustive small business database in the Nelson Mandela Bay Metropole did not allow the research to draw on a larger representative sample. Thus, this limitation has impeded in-depth statistical analysis that would have allowed the research to obtain more accurate findings. Further studies could investigate the reasons why in many cases financial institutions reject the funding of small businesses.
