- Description: In the higher education sector, a number of Higher Education Institutions (HEIs) are playing a leading role in promoting sustainable initiatives. Effectively managing these initiatives however can be a complex task and requires data and information from multiple aspects of operations. In an HEI, operating sustainably means ensuring financial sustainability, social sustainability, environmental sustainability and educational sustainability. In order to manage sustainability effectively, HEIs require an integrated tool that can provide information on all areas of sustainability. HEIs face a number of challenges in effectively managing sustainability information, such as siloed data and information, and poor sharing and communication of information. Business Intelligence (BI) can assist in overcoming many of the challenges faced by organisations in effectively managing strategic sustainability information. This study investigates both the constraints to effective sustainability information management and the challenges of BI. A BI framework to support effective strategic sustainability information management is proposed. Nelson Mandela Metropolitan University (NMMU) is one such HEI, which is affected by the challenges of managing strategic sustainability information. NMMU is therefore used as a case study in this research. A BI solution, Sustainable BI, was developed based on the proposed framework. The main goal of sustainable BI is to provide strategic management at NMMU with a tool that can provide integrated sustainability information that can assist in overcoming the challenges in effectively managing strategic sustainability information. Sustainable BI was evaluated by strategic management at NMMU who are responsible for managing sustainability at NMMU. The evaluation took place through a usability study. The study revealed to what extent Sustainable BI could effectively manage strategic sustainability information at NMMU. The BI framework was iteratively improved on based on the results of the evaluations. The contributions from this study are a model for sustainability management, a BI Framework to support strategic sustainability information management and a BI solution, Sustainable BI.

- Description: The study investigates the role of media in promoting free debate in Lesotho: A case study of democratic debate on People’s Choice (PC) FM “Thahameso” and Harvest FM “Tsa Mabatooa in Lesotho. Firstly, the study looked at the democratic communication in the volatile democracy of Lesotho, by providing historical factors of pre-independence and authoritarian governments, democrocatic governments prevailing and the dependence on South Africa. Secondly, the study provided literature on the role of broadcast media in different forms of government globally. Thirdly, it provides the analysis and transcription of one month’s recordings of the two political talk shows in Sesotho and identifies the communicative strategies used in this live on-air political discussion by talk show hosts, guests and callers. In these talk shows the researcher identifies the caller, host and guest behaviour and attitudes in discussions that relate the current political situation to the historical development of democracy in Lesotho alongside the economic and political influences from South Africa. The researcher also identifies that the talk show, guests and callers in the challenging political climate use traditional figurative expressions and biblical quotations to express their views. This leads the researcher to conclude that the political talk shows indeed facilitate participatory communication.

- Description: In South Africa the economic gaps imposed by the previous apartheid government aggravated economic inequalities and caused considerable disparities, which has resulted in high unemployment rates. Inequalities were also manifest in the neglect of infrastructural and service provision as well in the effective absence of independent governance among some race groups. This led to a call for pro-active initiatives by the post-1994 democratic government to remedy the living condition of the previously disadvantage people. As part of this poverty relief drive the South African government has embarked on a series of developmental initiatives in bringing infrastructure related service to the poor and to reduce the enormous prevailing backlog, with the aim of increasing community participation, improving service delivery and promoting the upliftment of the lives of poor people through the medium of local governance. This study investigated the integrated Development Planning, which has been undertaken in Cookhouse in Blue Crane Route Municipality in the Eastern Cape to respond to the prevailing poverty and underdevelopment among the poor communities.

- Description: In this day and age, Environmental issues are considered to be very pertinent in a business environment. Lee (2010) argues that the natural environment is not only important for the general population, but the concern for the natural environment has become increasingly important within the accounting practice. Lee (2010) references (Porter & Van der Linde, 1995; Schaltegger & Wagner, 2006; Lee, 2009), in supporting his argument that there has been increasing interest in the relationship between environmental and economic performance, that is to say reducing costs while simultaneously improving environmental performance. Organisation in the past decades have either opted to disregard or embrace change as a result of this global phenomenon. Within organisations current leaders have had to manage operations in their local areas with a global mindset. Hill (2011:4) defines globalisation as a process whereby barriers to cross border trade and investment are declining, perceived trading distances are shrinking, material culture is starting to look similar and where national economies are merging to an interdependent, integrated economic system. With the increased hype and awareness of environmental and sustainability issues within the manufacturing environment, certain companies have adopted best practices that focus on firms' production processes (Hart, 1995; Stead & Stead, 1995) that can result in cost advantage. Within the South African context, the government has put in place a legislative framework laid down by the South African Constitution that enforces the responsibility of sustainable use of natural resources and responsible management of process outputs such as waste, effluent and gas emissions. General Motors adopted an Environmental Management System. The fundamental principles of EMS are based on continuous improvement where most of improvement opportunities and challenges exist within the implementation stages. The fundamental questions the study seeks to address are: As General Motors South Africa put in place this sustainability tool, how does the company ensure that in line with continuous improvement, the improvements are sustained? What interventions can the company implement to drive the change to ensure that it improves the implementation of its Environmental Management System so as to reap the benefits as outlined? This research effort discussed recommendations for achieving the objective of developing a change management model for improving implementation of sustainability principles at General Motors South Africa. Based on the outcome of the survey and the interview, the current senior managers at General Motors South Africa have embraced environmental issues, but there is no clear indication that the future leaders will also do the same. Based on the eight steps for transforming an organisation by Kotter (2006), the following are recommendations: A communication strategy to all employees (including leadership) that will continuously articulate connections between new behaviours and corporate success throughout the organisation, and not limit to manufacturing operations. Secondly, the company needs to ensure that there are programmes in place for leadership development and succession.

- Description: For business firms to continue as going concerns, productivity is a primary goal. In order for the firms to remain productive, it is imperative that managers continuously explore ways of improving productivity and employee performance. Employee productivity, in particular, is the measurement of performance and competitiveness in any business firm. A competitive advantage enables a business firm to, amongst others, survive financially, expand its operations and grow its market share. Creativity and innovation are fundamental sources of competitive advantage. In order for a business to retain its competitive edge, it must effectively enhance employee productivity, creativity and innovation. The primary purpose of this study was to investigate a creativity model that could contribute to the enhancement of employee productivity. More specifically, the study investigated how employee productivity (the dependent variable) was influenced by the independent variables rewards, a climate conducive for creativity and innovation, employee creativity, self-esteem and performance intent. The sample consisted of 82 blue-collar employees from various manufacturing firms in Port Elizabeth. The empirical results revealed that the firms’ rewards for performance and their climates for creativity and innovation were positively related to the creativity of their employees. The creativity and self-esteem of their employees were positively related to their employees’ performance intentions, while collectively these three variables were positively related to their employees’ productivity. The managerial implications of these and other findings are discussed in the study.

- Description: The main purpose of this study is to provide a critical analysis of selected literary techniques in P.T. Mtuze’s prose narratives. This study seeks to analyse his style of writing in all his texts. The aspects of his style under stylistic techniques and criticism will serve as a foundation theory that will link the study to the analysis of definitions and referencing under imagery and its aspects; including humour, satire, idioms, proverbs, literary techniques, and figures of speech. Mtuze is noted as one of the most prolific writers due to his ingenuity in language skills, especially in isiXhosa. Mtuze is one of the best humoristic writers; hence he is popular due to applying humour in the prose works he wrote. This study is divided into seven chapters, and the theory which is used for this study is also scrutinised in order to get a sense of what the author intended to deliver through his texts.

- Description: Moneymaking schemes such as prostitution, drug dealing, fraud, corruption, pyramid schemes and the sale of counterfeit goods have been around for years. The taxing of these transactions/schemes has become a contentious issue. It has recently been reported in the press that SARS has lodged a claim for R183 million in income taxes against the estate of the slain mining magnate, Brett Kebble, in respect of the R2 billion allegedly stolen by him from the mining companies of which he was a director.4 It is further reported that the Master of the High Court has rejected the claim on the grounds that the amounts on which SARS sought to levy tax constituted money stolen by Kebble, and that stolen money is not subject to income tax. It has been reported that SARS is to take the Master’s decision in this regard on review.5 The Kebble case raises an interesting and unresolved tax issue and, in view of the large sum at stake, it may be a case that will go all the way to the Supreme Court of Appeal and bring long-overdue certainty to the law. The Income Tax Act No. 58 of 1962 (the Act) is of no assistance in determining the issue. Section 23(o) states that payments that are illegal in terms of Chapter 2 of the Prevention and Combating of Corrupt Activities Act No. 12 of 2004 or that constitute a fine or penalty for any “unlawful activity carried out in the Republic or in any other country if that activity.

- Description: This study researched team building as a tourism offering. Team building has particular potential to benefit tourism in the Western Region of the Eastern Cape. Team building has grown in popularity and is offered by several tourism operators in the Western Region of the Eastern Cape. Team building can be practiced throughout the year by the use of numerous indoor and outdoor activities thereby attracting participants and tourists. The activity involves a wide range of tourism-related services and facilities which shows its potential value as tourism resource. The research methodology for this study aimed to identify the link between team building and tourism. Additionally, the study draws attention to team buildings possible socio-economic value which is added to a tourism business’s offering range and its effect on the host destination. A survey was conducted among a randomly selected target population representing role-players involved in team building and tourism activities, for which a questionnaire was developed by adapting the SERVPERF model. This enabled the researcher to identify the team building participants’ level of satisfaction with the team building operator, activity and host destination. Emerging from the gained insight into the dynamics between team building offerings and tourism businesses, recommendations have been formulated as to the relevance of team building for a tourism businesses’ offering range and the impact on the host destination. The research study identified numerous beneficial spin-off effects for the Western Region of the Eastern Cape driven from team building activities. These benefits were an increase in awareness of the destination, improved image of the Western Region of the Eastern Cape, and tourist engagement in other tourism offerings during their stay at the destination, among others.

- Description: The International Affective Picture System (IAPS) was developed in an attempt to provide a standardised tool to elicit and measure emotions for research purposes. The IAPS is unique, in that it is completely pictorially based. An emotional response is stimulated by the pictures, which are then used to measure the emotional response. This has obvious benefits in South Africa. The overall aim of this study was to conduct a cross-cultural exploration of the IAPS, with a sample of South African university students, in order to come to an initial understanding of the measure’s performance within the South African context. A quantitative methodology was used, in order to reach the research aim and objectives. The overall research approach was exploratory and descriptive in nature and the actual data gathering consisted of a single measurement instance. The procedure for this study was based on that used by the developers of the IAPS to norm the instrument. Convenience sampling was used, resulting in a total sample of 169 participants, 31 male, and 136 female. For analysis purposes, participants were grouped according to a race and language combination, thus operationalising ethnicity. This resulted in four primary ethnic groupings. In summary, it was found that a large number of items seem to travel well in terms of equivalence. The correlations achieved and affective space plot are consistent with that outlined in the IAPS instruction manual, and are similar to international studies using the same procedure. However, when items were examined in greater detail, statistically significant differences raised concerns about the level of equivalence and suggested that not all items travel equally well. Similarly, although many items were statistically similar between the South African ethnic groups, differences were also found on specific items.

- Description: A key question that marketers and salespeople face is based on the dilemma of which customer to pursue and which not. This choice has far reaching effects in both company success. Investigating a client’s seriousness to make a purchase at the time of an enquiry is key. This will assist the firm in determining which future clients offer the firm the most potential value in sales turnover and company profits. By taking the client’s background and history into consideration the marketer has the opportunity to determine which clients have or have not previously committed to the firm and which did not. By profiling the customer, providing a yardstick against which one can measure probability of a purchase can be developed. New or prospective customer against those attributes of customers can then be benchmarked against the attributes that attest to whether interest and intention to purchase can be converted into a sale. Identifying these customers who will be most likely to make a purchase is a very important area of study for any business that focuses on the marketing and sales of products or services. Having an accurate profile of potential customers, of who will buy and who will not, will play a key role in the success of any organization. The focus of this study will be on investigating the profile of a potential customer/company as a benchmark for sales lead qualification. The profile will also be a precursor to determining the lifetime value of the prospective customer. Profiling of high sales potential customers is a management issue. It directly influences the number of hours key personnel in the sales department spend on key tasks, which can alternatively be spent more productively on other projects.

- Description: Place branding has grown in popularity since the late 1990s. In this regard, place branding is an endeavour to not only construct an image or message of a place but also to communicate and manage it. Place branding can be viewed from a functionalist point of view as a strategic instrument to be managed in a similar manner as a product or corporate brand in order to enhance competitiveness. The focus of place branding has overwhelmingly been on the customers who are mainly tourists. However, there have been recent calls to take into account the perspectives of others stakeholders, in particular internal residents, in the place branding process. It has been noted that place branding is effective through its ability to authentically represent the setting of its constituents and through it to reveal a compelling narrative of the place. This authentic setting is represented by the place identity, which can be discovered from the perspectives of the place‟s internal residents. The current study was anchored in stakeholder theory and set out to propose a simple exploratory model for understanding place identity through the perspectives of internal residents. The study explored various frameworks and models proposed in the literature up to date to understand place identity. The overarching variables were filtered out from the different frameworks and an exploratory place identity framework was proposed. A non-experimental study was carried out in the city of Nelson Mandela Bay. The study was exploratory and its variables had not been previously tested in the city. A questionnaire, which was partly self-administered and partly administered through face-to-face interviews, was distributed electronically and manually. The framework proposed variables were city role, cognitive evaluations, envisioned future as well as affective evaluations and they were operationalised from the literature. The relationship between the variables was confirmed through correlation analysis. The hypotheses in the study were tested through descriptive statistics, correlation analysis, ANOVA, t-tests and Chi-squared tests. A destination identity framework for Nelson Mandela Bay.

- Description: Information and communication technologies (ICTs) have been widely researched as a mechanism for improving the socio-economic status of disadvantaged, rural communities. In order to do this numerous technology-based initiatives have been introduced into disadvantaged, rural communities to assist them in various aspects of their lives. Unfortunately, even when the proposed benefit of a particular technology is clearly evident to its initiators, the adoption by the target users is often uncertain. This has also been the case with e-commerce in agriculture. Despite the numerous benefits of e-commerce for agricultural producers, the uptake has been low. Trust is a critical pre-condition for the adoption of e-marketplaces. E-marketplaces expose consumers to the risk of non-delivery or misrepresentation of goods ordered and the misuse of personal information by external parties. Additionally, the time investment needed to make a shift to e-marketplaces and the opinions of important reference groups affects the user’s willingness to trust and depend on an e-marketplace. This study was undertaken to assess the extent to which rural users with limited ICT experience would trust and, consequently, adopt an e-marketplace to support agricultural trade. A pragmatic philosophy was adopted in this study, indicating that the researcher’s view of reality is founded on the practical implications and outcomes that are observed. This study used a Canonical Action Research strategy to design, develop and deploy a voice based e-marketplace to assist the trading activities of a Western Cape based aloe community. The community was allowed to utilise thee-marketplace over a period of eight weeks. Thereafter, interviews were held with the participants to investigate their perceptions of the technology. As a result, a model proposing the factors that must be in place for trust to be achieved in a voice based e-marketplace was proposed. The study found that the trustworthiness of a technology results from the technology’s technical capability to satisfy the needs of its users reliably. Usability and security were found to be important determinants of the trustworthiness of a technology. Furthermore, the requirements elicitation process was found to be central to achieving trust as it defines the necessary criteria for developing secure, usable, functional, and reliable technologies that meet the needs of their users.

- Description: In several countries around the world, grain commodities are traded as assets on stock exchanges. This indicate that the market and effectively the prices of the grain commodities in such countries, are controlled by several local and international economic, political and social factors that are rapidly changing. As a result, the prices of some grain commodities are volatile and trading in such commodities are prone to price-related risks. There are different trading strategies for minimising price-related risks and maximising profits. But empirical research suggests that making the right decision for effective grain commodities trading has been a difficult task for stakeholders due to high volatility of grain commodities prices. Studies have shown that this is more challenging among grain commodities farmers because of their lack of skills and the time to sift through and make sense of the datasets on the plethora of factors that influence the grain commodities market. This thesis focused on providing an answer for the main research problem that grain farmers in South Africa do not take full advantage of all the available strategies for trading their grain commodities because of the complexities associated with monitoring the large datasets that influence the grain commodities market. The main objective set by this study is to design a framework that can be followed to collect, integrate and analyse datasets that influence trading decisions of grain farmers in South Africa about grain commodities. This study takes advantage of the developments in Big Data and Data Science to achieve the set objective using the Design Science Research (DSR) methodology. The prediction of future prices of grain commodities for the different trading strategies was identified as an important factor for making better decisions when trading grain commodities and the key factors that influence the prices were identified. This was followed by a critical review of the literature to determine how the concepts of Big Data and Data Science can be leveraged for an effective grain commodities trading decision support. This resulted in a proposed framework for grain commodities trading. The proposed framework suggested an investigation of the factors that influence the prices of grain commodities as the basis for acquiring the relevant datasets. The proposed framework suggested the adoption of the Big Data approach in acquiring, preparing and integrating relevant datasets from several sources. Furthermore, it was suggested that algorithmic models for predicting grain commodities prices can be developed on top of the data layer of the proposed framework to provide real-time decision support. The proposed framework suggests the need for a carefully designed visualisation of the result and the collected data that promotes user experience. Lastly, the proposed framework included a technology consideration component to support the Big Data and Data Science approach of the framework. To demonstrate that the proposed framework addressed the main problem of this research, datasets from several sources on trading white maize in South Africa and the factors that influence market were streamed, integrated and analysed. Backpropagation Neural Network algorithm was used for modelling the prices of white maize for spot and futures trading strategies were predicted. There are other modelling techniques such as the Box-Jenkins statistical time series analysis methodology. But, Neural Networks was identified as more suitable for time series data with complex patterns and relationships. A demonstration system was setup to provide effective decision support by using near real-time data to provide a dynamic predictive analytics for the spot and December futures contract prices of white maize in South Africa. Comparative analysis of predictions made using the model from the proposed framework to actual data indicated a significant degree of accuracy. A further evaluation was carried out by asking experienced traders to make predictions for the spot and December futures contract prices of white maize. The result of the exercise indicated that the predictions from the developed model were much closer to the actual prices. This indicated that the proposed framework is technically capable and generally useful. It also shows that the proposed framework can be used to provide decision support about trading grain commodities to stakeholders with lesser skills, experience and resources. The practical contribution of this thesis is that relevant datasets from several sources can be streamed into an integrated data source in real-time, which can be used as input for a real-time learning algorithmic model for predicting grain commodities prices. This will make it possible for a predictive analytics that responds to market volatility thereby providing an effective decision support for grain commodities trading. Another practical contribution of this thesis is a proposed framework that can be followed for developing a Decision Support System for trading in grain commodities. This thesis made theoretical contributions by building on the information processing theory and the decision making theory. The theoretical contribution of this thesis consists of the identification of Big Data approach, tools and techniques for eradicating uncertainty and equivocality in grain commodities trading decision making process.

- Description: South Africa is one of the countries in the world with the highest number of people living with HIV/AIDS. Workplace HIV/AIDS programmes have been singled out by the Government as one of the measures to fight against the spread of the disease. However, it is quite concerning that managers in most organisations are very reluctant to actively participate in the programmes. One of such organisations is the Chris Hani District Municipality. Reluctance by managers to participate in these programmes has given rise to effects such as lower level employees also not willing to participate in the programmes; thereby undermining efforts by the municipality and the National Government as a whole to fight against the spread of the disease in South Africa. This study has developed a framework that may enable municipal managers to participate in HIV/AIDS programmes in the municipality. In addition the study has also explored factors that discourage managers from participating in HIV/AIDS programmes. The study took place in the Chris Hani municipality. The sample population was municipal managers from the different directorates. The methodological approach was quantitative. Data was collected with use of a questionnaire. The questionnaire was distributed physically and electronically by the researcher. The findings of the study show that in order for managers to actively participate in the programmes of HIV/AIDS, measures should be put place to enhance the following: self-awareness, positive attitude, effective communication, management involvement, management support, and relationship building. The researcher hopes that the study will not only enhance management participation in the Chris Hani municipality, but also other municipalities and organisations in South Africa interested in the fight against the spread of the HIV/AIDS disease.

- Description: Vast amounts of data are collected on a daily basis, making it difficult for humans to derive at valuable information to make effective decisions. In recent years, the field of Business Intelligence (BI) and Information Visualisation (IV) have become a key driver of an organisation’s success. BI tools supporting decision making need to be accessible to a larger audience on different levels of the organisation. The problem is that non-expert users, or novice users, of BI tools do not have the technical knowledge to conduct data analysis and often rely on expert users to assist. For this reason, BI vendors are shifting their focus to self-service BI, a relatively new term where novice users can analyse data without the traditional human mediator. Despite the proliferation of self-service BI tools, limited research is available on their usability and design considerations to assist novice users with decision making and BI analysis. The contribution of this study is a conceptual framework for designing, evaluating or selecting BI tools that support non-expert users to create dashboards (the BI Framework). A dashboard is a particular IV technique that enables users to view critical information at a glance. The main research problem addressed by this study is that non-expert users often have to utilise a number of software tools to conduct data analysis and to develop visualisations, such as BI dashboards. The research problem was further investigated by following a two-step approach. The first approach was to investigate existing problems by using an in-depth literature review in the fields of BI and IV. The second approach was to conduct a field study (Field Study 1) using a development environment consisting of a number of software components of which SAP Xcelsius was the main BI tool used to create a dashboard. The aim of the field study was to compare the identified problems and requirements with those found in literature. The results of the problem analysis revealed a number of problems in terms of BI software. One of the major problems is that BI tools do not adequately guide users through a logical process to conduct data analysis. In addition, the process becomes increasingly difficult when several BI tools are involved that need to be integrated. The results showed positive aspects when the data was mapped to a visualisation, which increased the users’ understanding of data they were analysing. The results were verified in a focus group discussion and were used to establish an initial set of problems and requirements, which were then synthesised with the problems and requirements identified from literature. Once the major problems were verified, a framework was established to guide the design of BI dashboard tools for novice users. The framework includes a set of design guidelines and usability evaluation criteria for BI tools. An extant systems analysis was conducted using BI tools to compare the advantages and disadvantages. The results revealed that a number of tools could be used by non-experts, however, their usability hinders users. All the participants used in all field studies and evaluations were Computer Science (CS) and Information Systems (IS) students. Participants were specially sourced from a higher education institution such as the Nelson Mandela Metropolitan University (NMMU). A second field study (Field Study 2) was conducted with participants using another traditional BI tool identified from the extant systems analysis, PowerPivot. The objective of this field study was to verify the design guidelines and related features that served as a BI Scorecard that can be used to select BI tools. Another BI tool, Tableau, was used for the final evaluation. The final evaluation was conducted with a large participant sample consisting of IS students in their second and third year of study. The results for the two groups revealed a significant difference between participants’ education levels and the usability ratings of Tableau. Additionally, the results indicated a significant relationship between the participants’ experience level and the usability ratings of Tableau. The usability ratings of Tableau were mostly positive and the results revealed that participants found the tool easy to use, flexible and efficient. The proposed BI Framework can be used to assist organisations when evaluating BI tools for adoption. Furthermore, designers of BI tools can use the framework to improve the usability of these tools, reduce the workload for users when creating dashboards, and increase the effectiveness and efficiency of decision support.

- Description: The aim of this study was to explore the experiences of students with visual impairments in a selected state university in Zimbabwe in order to develop a framework for their inclusion. The study was necessitated by the increased enrolment of students with visual impairments in universities worldwide in response to inclusion in education and the continuous search for the best placement model for students with disabilities. Studies conducted internationally show that students with visual impairments have unique learning needs which must be addressed if their inclusion in universities is to be successful. The study was informed by Bronfenbrenner’s ecological and Bandura’s agentic theories, both of which stress the bi-directional relationship between an individual and the environment. The transformative paradigm which guided this study, lays emphasis on the need to improve the social situation of individuals with disabilities in order to bring about a more equitable society. Since the study intended to gain an understanding of how students with visual impairments interpret their experiences within a selected state university in Zimbabwe which practices inclusion, the qualitative case study design was used. Purposeful sampling was also used in the selection of both the university studied and the participants. Data generation methods employed included the semi-structured interview, photo-voice, document analysis and observation. Data generated were analysed following emergent themes that were used to answer the research questions. Findings revealed that the university started enrolling students with visual impairments in 2004 and has since established a Disability Resource Centre which is equipped with assistive devices and is manned by caring staff. Findings revealed a glaring absence of a university policy on inclusion. The guiding principles used did not clearly articulate issues of inclusion. The students’ positive experiences resulted from single rooms allocated to them and the support received from friends and caring staff. Negative experiences emanated from bureaucratic admission procedures, challenges of adjusting to university life in the absence of orientation and mobility training, financial challenges, hostile social environment and the students’ perceptions of themselves. The students suggested that the university should assist them with fees and expressed their wish to be consulted on matters that concern them. They xviii also suggested close co-operation between the administration and the Disability Resource Centre. The conclusion reached was that although the university was sensitive to issues of inclusion, there were still some deficiencies in the system that were impacting negatively on the inclusion of students with visual impairments. The study recommended a framework which shows the different committees and support systems which can be formed at different levels to facilitate the development of a comprehensive policy on inclusion and expedite its implementation. The involvement of students with visual impairments in the different committees was also recommended. This would afford them the chance to exercise their agentic resources and be involved in matters which concern them, rather than rely on decisions made by sighted individuals who might not possess adequate knowledge of what visual impairment entails.

- Description: The use of technology in society moved from satisfying the technical needs of users to giving a lasting user experience while interacting with the technology. The continuous technological advancements have led to a diversity of emerging security concerns. It is necessary to balance security issues with user interaction. As such, designers have adapted to this reality by practising user centred design during product development to cater for the experiential needs of user - product interaction. These User Centred Design best practices and standards ensure that security features are incorporated within End User Programs (EUP). The primary function of EUP is not security, and interaction with security features while performing a program related task does present the end user with an extra burden. Evaluation mechanisms exist to enumerate the performance of the EUP and the user’s experience of the product interaction. Security evaluation standards focus on the program code security as well as on security functionalities of programs designed for security. However, little attention has been paid to evaluating user experience of functionalities offered by embedded security features. A qualitative case study research using problem based and design science research approaches was used to address the lack of criteria to evaluate user experience with embedded security features. User study findings reflect poor user experience with EUP security features, mainly as a result of low awareness of their existence, their location and sometimes even of their importance. From the literature review of the information security and user experience domains and the user study survey findings, four components of the framework were identified, namely: end user characteristics, information security, user experience and end user program security features characteristics. This thesis focuses on developing a framework that can be used to evaluate the user experience of interacting with end user program security features. The framework was designed following the design science research method and was reviewed by peers and experts for its suitability to address the problem. Subject experts in the fields of information security and human computer interaction were engaged, as the research is multidisciplinary. This thesis contributes to the body of knowledge on information security and on user experience elements of human computer interaction security regarding how to evaluate user experience of embedded InfoSec features. The research adds uniquely to the literature in the area of Human Computer Interaction Security evaluation and measurement in general, and is specific to end user program security features. The proposed metrics for evaluating UX of interacting with EUP security features were used to propose intervention to influence UX in an academic setup. The framework, besides presenting UX evaluation strategies for EUP security features, also presents a platform for further academic research on human factors of information security. The impact can be evaluated by assessing security behaviour, and successful security breaches, as well as user experience of interaction with end user programs.

- Description: For many decades, black rural women have been underprivileged, illiterate, with limited access to resources in general. They were not only faced with discrimination and segregation, both in organised labour markets and in informal sector employment, but they also had different legal rights regarding inheritance, land and credit. They got less education if any at all, lower pay, although they worked longer hours and had less access to professional training then men (Moser, 1993). For many years, development projects have been technical projects or construction projects focussing on construction work. Since the 1970s, possibilities for women participating in the planning, management and maintenance of development projects were broadened. In many of the projects, the project managers/planners would say that they have worked with the villages, leaders and committees, yet the majority of the time, they work with males living in the village. Women are usually targeted only for health education. More gender sensitive approach was shown in the 1980s, when women had several roles to play in matters of development (Syme, 1992: 6). In the past couple of years, South Africa has had a growing acceptance of a gender-focused approach to development. In accepting the gender-focused approach to development, the country went as far as creating a department of women, children and disabled to fight for the rights of women, children and the disabled. The country also signed a protocol of the SADC on gender and development. This protocol encompasses commitments made in all regional, global and continental instruments for achieving gender equality. It enhances these instruments by addressing gaps and setting specific, measurable targets where these do not already exist. The protocol advances gender equality by ensuring accountability by all SADC member states, as well as providing a forum for the sharing of best practices, peer support and review (SADC, 2008).

- Description: The marketing of infant feeding products is almost impossible as the infant nutrition industry is highly regulated. Despite operating under strict regulations, the infant formula manufacturing companies still generate high revenues on an annual basis. The infant formula manufacturing industry operates under a value chain which can be broken down into six sequential steps. These steps are: (1) Translational science; (2) Product development; (3) Clinical research; (4) Product notification; (5) Reimbursement granting and (6) Product marketing. Medical nutrition companies aspire to understand product requirements of healthcare professionals and medical representatives. This is to enable direct investment to acquire market share without wasting resources. The medical nutrition industry currently makes use of medical representatives to execute product marketing. Manufacturing companies invest a lot of money into developing their products, employing and training medical representatives and trust that this will be enough to persuade healthcare professionals to recommend their products to parents. This study analyses the main contributing factors that enhance prescription of specialised infant formula by healthcare professionals. This study was conducted in a positivistic paradigm by making use of a quantitative approach. Healthcare professionals from Port Elizabeth, working with paediatric patients were included in this study. The healthcare professionals were chosen by a convenience sampling method and were then interviewed. The empirical interview results were substantiated with the interpretive findings which were in the form of verbatim statements extracted directly from the research questionnaire. Linkage between the dependable variable (prescription) and independent variables (manufacturing company; product composition; cost of product; medical representative and peers) were established and analysed. The research revealed that prescription behaviour is an important construct which can be measured in medical practices. Prescription behaviour is correlated with positive business and medical outcomes and manufacturing companies are able to exert influence over it through the identified variables. Of these variables, efficacy of vii a product, trusted manufacturing company and the medical representatives were found to have direct and significant effects. Healthcare professionals tend to prescribe a specialised infant formula if they have seen results and trust the outcome of the product. It is advisable for manufacturing companies to exert great effort before appointing a medical representative, to make sure that the right candidate represents the face of the company.

- Description: In this treatise a SEIR model for the transmission of tuberculosis was proposed. It assumes that the latent infected individuals progress to active tuberculosis through endogenous reactivation and exogenous re-infection and that the individuals who have recovered from the disease through treatment are not immune to tuberculosis re-infection. While most features of the original model were kept, the model was modified to incorporate two control measures in the form of post-exposure tuberculosis prophylaxis for the treatment of latent individuals and tuberculosis therapeutics for the treatmentof individuals with active tuberculosis. Mathematical analysis of the modelwas done under the assumption that the two control measures are positiveconstants. The disease-free equilibrium point was locally asymptotically stable when the basic reproduction number was less than unity and unstable when this epidemic threshold exceeds unity. An optimal control problem was formulated and the necessary conditions for optimality were derived.The numerical results based on data from Port Elizabeth suggest that using both forms of control measures simultaneously is more effective in reducing the total number of infected individuals than applying single controls separately.
