- Description: This study investigated family grief and resilience following a child’s death. Representing 23 families, 35 bereaved parents completed biographical questionnaires, the Family Hardiness Index, and the Family Attachment and Changeability Index 8. Significant positive correlations were found between family hardiness and family adaptation, and between parents’ age and family hardiness. Using grounded theory, interviews allowed for the formulation of categories including grief, continuing bonds, external support, religion, and family hardiness. The study reveals the need for exploring unique experiences of families bereaved by children’s deaths and identifies family hardiness as a potential resilience factor for this population

- Description: The human immunodeficiency virus / acquired immune deficiency syndrome pandemic (HIV/AIDS) continues to increase in prevalence worldwide, particularly in South Africa. There is a concurrent and distinct increase in the prevalence of HIV/AIDS and HIV-related diseases in the paediatric population in South Africa, particularly those using public sector health services, with a corresponding increase in morbidity and mortality rates (Abdool Karim & Abdool Karim, 2010:363), which impacts greatly on paediatric healthcare services. Adding to this, the provision of paediatric antiretroviral care has numerous stumbling blocks, not least of which is lack of decentralisation of facilities to provide treatment. There is the additional shortage of staff, which includes staff that are comfortable dealing with children, lack of training programmes on the provision of antiretroviral therapy to children, and minimal on-site mentorship of staff regarding HIV/AIDS disease in children. This lack of capacity in the healthcare system means that not all of those who require treatment will be able to access it, and this is particularly pertinent to paediatric patients (Meyers et al., 2007:198). Therefore the purpose of this research was to develop a nursing model that would assist healthcare professionals, in particular professional nurses, to optimise the comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy at PHC clinics. To achieve the purpose of this study, a theory-generating design based on a qualitative, explorative, descriptive and contextual approach was implemented by the researcher to gain an understanding of how the healthcare professionals and parents/caregivers of HIV-positive children experienced the comprehensive treatment, care and support provided at primary healthcare clinics. The information obtained was used to develop a chronic care coordination model for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy. The study design comprised the following four steps: Step One of the research design focused on the identification, classification and definition of the major concepts of the study. This involved describing and selecting the research population and the sampling process prior to conducting the field work which comprised in-depth interviews with two groups of participants, namely healthcare professionals and parents/caregivers who accompany their HIV-positive children to PHC clinics in order to receive antiretroviral therapy. Step Two of the research design focused on the development of relationship statements in order to bring clarity and direction to the understanding of the phenomenon of interest. Step Three of the design concentrated on the development and description of the chronic care coordination model for optimising comprehensive treatment, care and support for HIV-positive children who require antiretroviral therapy in order to ensure a well-managed child on ART. A visual representation of the structure of the model for chronic care coordination was given and described as well as a detailed description of the process of the model. Step Four was the last step of the research design and its focus was the development of guidelines for the operationalisation of the model for chronic care coordination for the optimisation of comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy at PHC clinics. Guidelines and operational implications for each of the five sequential steps of the model were developed. The evaluation criteria of Chinn & Kramer (2008:237‒248) were used to evaluate the model. It is therefore concluded that the researcher succeeded in achieving the purpose for this study because a chronic care coordination model that is understandable, clear, simple, applicable and significant to nursing practice has been developed for use by healthcare professionals, particularly professional nurses, in order to optimise the comprehensive treatment, care and support for HIV-positive children requiring antiretroviral therapy at primary healthcare clinics.

- Description: The relationship between the fabric parameters, as independent variables, and the comfort related properties, as dependent variables, of commercial suiting fabrics, containing both natural and man-made fibres, have been studied. The fabric parameters measured in the study were mass, thickness, density, and air permeability. The comfort related properties, tested on a Permetest instrument, included water vapour permeability, water vapour resistance, and thermal resistance, with the moisture permeability index being derived. A total of 26 commercial suiting fabrics, covering a wide range of mass, as well as different fibre types and blends and fabric structures, was tested. The fibres covered, included wool, polyester, viscose, and cotton, while the fabric structures covered were 1x1 plain weave, 2x1 twill and 2x2 twill weave. The objectives of this study were to determine the empirical relationships between the measured fabric properties and the measured comfort related properties, and to determine the role, if any, of fibre type and fabric structure, since many claims are made in practice concerning the relative advantages, in terms of comfort, of a specific fibre type or blend, or fabric structure, over others, some of which being supported by research results. Since the fabrics covered, were commercial and were not engineered so that the different fabric parameters (independent variables) and fibre type and blend, as well as fabric structure could be varied independently of each other, the effects of the various fabric parameters on the fabric comfort related properties were determined and quantified by multiple regression analyses (multi-linear and multi-quadratic), and the best fit regression equations, and contribution of each parameter to the overall fit established. It was found that fabric thickness and fabric mass had the largest effect on the comfort related properties as measured here, fabric mass determining, to a large extent, water vapour permeability, and fabric thickness, thermal resistance. The rest of the fabric parameters included in the study had only a relatively small effect on the measured comfort related properties. The influence of fabric parameters, with particular reference to mass and thickness, on the measured comfort related properties, were much greater than that of fibre type or blend, or fabric structure. It was, therefore, concluded from this study, that the fabric parameters, as opposed to the intrinsic characteristics of a particular fibre, whether natural or man-made, largely determined those fabric comfort related properties measured here.

- Description: The principle of the right to strike is Internationally recognised. Although the right to strike is not set out explicitly in the International Labour Organizations (ILO) Conventions and Recommendations. It has been discussed on several occasions in the International Labour Conference during the course of preparatory work on instruments dealing with related topics, but for various reasons this has never given rise to international standards (Conventions or Recommendations) directly governing the right to strike. The ILO has determined that the right to strike can be derived from the right to Freedom of Association. The ILO Committee does however recognises certain limitations on the right to strike such as not finding any objection to national legislation that would prohibit the right to strike of armed or police forces. Both the Committee on Freedom of Association and the Committee of experts were also mindful, where public servants are concerned, that the recognition of the right to association of public servants in no way prejudges the question of the right of public servants to strike. The ILO also makes provision for the establishment of essential services as to ensure the continuation of services were the interruption of such would endanger the life, personal safety or health of the whole or part of the population. In this limitation it however holds that a “minimum safety service” may be imposed to ensure the safety of persons, the prevention of accidents and the safety of machinery and equipment In our Constitution, the supreme law of the Country, the right to strike is enshrined and protected in section 23 under the bill of rights. The Constitution however allows enabling legislation, under specific circumstances, to limit a right listed in section 23. The Labour Relations Act (LRA) places a limitation on the right to strike, specifically providing that no person may take part in a strike if that person is engaged in an essential service. Because the right to strike is so important, a limitation of these kind needs to be justified and, to be justified it needs, among other things, to be limited. In section 72 of the LRA provision is made for a minimum service within a designated essential service. Therefore, the ambit of the designated essential service is shrunk to the minimum service and those employees who were denied the right to strike while the broader essential service designation was in place, but who fall outside the defined minimum service, regains the right to strike. The concept of minimum services has however became a matter of regular discussion and debate. The concept of minimum services is not defined to the letter but it is regarded as the minimum service an industry or workplace would require as to ensure interruption of services would not endanger the life, personal safety or health of the whole or part of the population. Our legislatures have also been grappling with the concept of essential and minimum services. They have developed a comprehensive set of amendments trying to address some of the concerns in the composition, powers and functions of the Essential Services Committee (ESC). It is debatable if these proposed amendments would bring forth the necessary change to address these concerns or just become a further bureaucratic hindrance and due to the extreme complexity may even pose a limitation on the right to strike. There is also no differentiation made in the current labour legislation and the proposed amendments, between the public service and the private sector in application of the principle of essential and minimum services. Implementation of these principles in the public services has shown to be extremely challenging. Part of the proposed amendments however makes provision for the specific inclusion of government in the composition of the ESC. It is viewed by the drafters, that the introduction of government nominees to be an innovation to ensure that government is adequately represented on the essential services committee in its capacity as an employer, as a high proportion of essential service matters occur within the public service. This may be viewed as contrary to International standards as the ILO makes clear provision for a differentiated interpretation of the right to freedom of association, the right to strike, essential services and minimum services for people performing functions in the name of the State (public servants). The concept of public servant varies considerably from one country to another. Germany within their governance structure makes provision for a differentiation between civil servants and public servants and the labour rights the two groups may have. In France the military, police and prison services does not have the right to strike. In India public service employees have very limited organising and collective bargaining rights. In Brazil the police and the military do not have the right to strike and there are no legal provisions concerning the right to strike for civil servants. This is in strong contrast with the South African model. The South African Constitution and National Legislation does not allow for a differentiation in the application of labour legislation in the public service and the private sector. The application of the principles of labour relations and more specifically that of the right to strike and the determination of essential services must differ in the public services from that of the private sector. The public service is unique in that when workers in strike action it is not a purely defined labour process between an employer and employees but the public at large becomes a third player within the process. When public servants engage in industrial action they do not only deprive the community of certain rights, but indirectly deprive themselves from the same rights. There has been a resistant fear to implement the provisions of minimum services within the designated essential services within the public service, mainly because of the challenges in conceptualization of the practical implementation of the same. The environment created by the LRA does not specifically provide for the unique circumstances of the public service. The right to strike is a fundamental right for workers and therefore public servants won’t forfeit such. There is a recognition that the State needs to deliver services which will necessitate the application of the principle of essential services. However the answer will be in how minimum services is determined within these essential services. An answer that may not necessarily be contained within the Labour Relations Act.

- Description: The modern organisation relies heavily on information to function effectively. With such reliance on information, it is vital that information be protected from both internal (employees) and external threats. The protection of information or information security to a large extent depends on the behaviour of humans (employees) in the organisation. The behaviour of employees is one of the top information security issues facing organisations as the human factor is regarded as the weakest link in the security chain. To address this human factor many researchers have suggested the fostering of a culture of information security so that information security becomes second nature to employees. Information security culture as defined for this research study exists in four levels namely artefacts, espoused values, shared tacit assumptions and information security knowledge. An important step in the fostering of an information security culture is the assessment of the current state of such a culture. Gaps in current approaches for assessing information security culture were identified and this research study proposes the use of a control framework to address the identified gaps. This research study focuses on the assessment of information security culture and addresses 5 research objectives namely 1) to describe information security culture in the field of information security, 2) to determine ways to foster information security culture in an organisation, 3) to demonstrate the gap in current approaches used to assess information security culture, 4) to determine the components that could be used for the assessment of information security culture for each of the culture’s underlying levels and 5) to describe a process for the assessment of information security culture for all four levels. This research study follows a qualitative approach utilising a design science strategy and multi-method qualitative data collection techniques including literature review, qualitative content analysis, argumentation, and modelling techniques. The research methods provide a means for the interpretation of the data and the development of the proposed control framework.

- Description: This study sought to find out the extent to which decentralisation has brought about development in the rural areas in Malawi, specifically focusing on Salima District Council. It sought the views from the local communities themselves and government officials at district level on decentralisation in relation to rural development. Although the study used both qualitative and quantitative approaches, it was predominantly qualitative. As such, it used mixed methods of data collection, which included in-depth interviews, direct observations, questionnaires, focus group discussions (FGDs) and documentary search. Qualitative data was developed into themes and concepts and was subsequently interpreted in a trustworthy manner so as to reflect the true meaning of the data. In other words, explanations were attached to each theme or concept in an attempt to give the meaning of the data. The study found out that decentralisation is effective in terms of rural development such that local people are able to demand for services of their choice from local governments but the main challenge or constraint is availability of financial resources to cater for all the demanded public services. Other major barriers to rural development include capacity deficiencies at district and grassroots level and tensions among key stakeholders competing to maximize their role in local governments. Basing on these findings, and financial resources being the major barrier to rural development, the study recommends that Government should make sure that enough financial resources are released and channelled to district councils to cater for the needs of the communities. The study also recommends that councils should strive to generate more local revenues to cope up with the demand from the communities. And finally, the study recommends that Government should recognize local governments as entities on which is bestowed a huge responsibility of improving socio-economic conditions of the rural areas where 87 percent of the population lives, therefore provision of resources and enabling legislation to enhance rural development should be the primary focus. Of course, these recommendations should be understood within the context of the studied district. Otherwise there is potential for different and expanded recommendations if one replicated the study to cover the entire country.

- Description: This study sought to find out the extent to which decentralisation has brought about development in the rural areas in Malawi, specifically focusing on Salima District Council. It sought the views from the local communities themselves and government officials at district level on decentralisation in relation to rural development. Although the study used both qualitative and quantitative approaches, it was predominantly qualitative. As such, it used mixed methods of data collection, which included in-depth interviews, direct observations, questionnaires, focus group discussions (FGDs) and documentary search. Qualitative data was developed into themes and concepts and was subsequently interpreted in a trustworthy manner so as to reflect the true meaning of the data. In other words, explanations were attached to each theme or concept in an attempt to give the meaning of the data. The study found out that decentralisation is effective in terms of rural development such that local people are able to demand for services of their choice from local governments but the main challenge or constraint is availability of financial resources to cater for all the demanded public services. Other major barriers to rural development include capacity deficiencies at district and grassroots level and tensions among key stakeholders competing to maximize their role in local governments. Basing on these findings, and financial resources being the major barrier to rural development, the study recommends that Government should make sure that enough financial resources are released and channelled to district councils to cater for the needs of the communities. The study also recommends that councils should strive to generate more local revenues to cope up with the demand from the communities. And finally, the study recommends that Government should recognize local governments as entities on which is bestowed a huge responsibility of improving socio-economic conditions of the rural areas where 87 percent of the population lives, therefore provision of resources and enabling legislation to enhance rural development should be the primary focus.

- Description: The strict and narrow scope of the general deduction formula may result in taxpayers being denied deductions for business expenditure, which are clearly and legitimately incurred in the course of operating their businesses, which in turn will result in an increase in tax costs, an important component of business costs. Although audit fees often fail the deductibility test, in general they are regarded by taxpayers as automatically deductible despite the fact that such fees were not incurred in the production of income. The deductibility of audit fees reached the High Court recently for the first time in the MTN case. It was argued by the South African Revenue Service (SARS) in this case that audit fees should never been allowed as a deduction because the role of an auditor does not relate to the production of income and that an auditor’s duty is restricted to verification of financial information ex post facto for the benefit of investors, creditors and other users of the financial information. The Court held that statutory audit fees should be deductible relying on the basis of the time spent during the audit in verifying deductible and non-deductible income. It is concluded by the author that law which creates uncertainty needs to be updated in keeping with the Government’s intention of creating a business environment in order to promote commerce and entrepreneurship. It is therefore proposed that all audit fees relating to statutory audits should be declared as a specific statutory deduction to ensure legal certainty.

- Description: Citizens interact with government departments and agencies for public services and goods which lead to a service encounter between a public official and client. Various initiatives and policies have been developed and are being implemented in the public service to adopt a client-centred approach to service delivery. The White Paper on the Transformation of the Public Service of 1997, identifies the eight Batho Pele principles which sets the framework for implementation of service quality within the South African public service. Government departments are expected to implement measurable service standards to determine levels of service quality to be met that will define levels of client satisfaction with service provision. The assessment of the service encounter by the client informs perceived levels of satisfaction held. This assessment of service quality by clients is therefore value-laden, subjective and periodic. The study focused on the implementation of measures to create and maintain a clientcentric public service in South Africa that would lead to levels of client satisfaction with service quality. The study assessed the implementation and maintenance of service quality at the Social Security Agency of South African the Eastern Cape. The SASSA is responsible for the disbursement of various social grants to facilitate a quality of life as enshrined by the Bill of Rights in the Constitution of South Africa, 1996. The focus of the study was linked to beneficiary maintenance and customer care at SASSA. The study included three different sample groups namely the clients, officials engaged in grant administration and different levels of management which included senior management, district and area managers. The findings revealed that the SASSA has implemented numerous new programmes aimed at a client-centric approach to service delivery. Analysis of the findings revealed expectation as well performance gaps which indicated that officials do not comply with the protocols of the agency and the Batho Pele principles. The promised service standards specified within the SASSA Customer Care Charter is not being realised which fundamentally indicate inefficient and ineffective monitoring of compliance with norms and standards. A conclusion drawn therefore is that the human dignity of clients in search of socials assistance who chiefly constitute vulnerable groups is being infringed. Three key service quality dimensions are identified that needs intervention for improved service quality. These dimensions include tangibility, assurance and responsiveness of functional components identified in respect of nine themes.

- Description: The Internet is becoming increasingly interwoven in the daily life of many individuals, organisations and nations. It has, to a large extent, had a positive effect on the way people communicate. It has also introduced new avenues for business and has offered nations an opportunity to govern online. Nevertheless, although cyberspace offers an endless list of services and opportunities, it is also accompanied by many risks. One of these risks is cybercrime. The Internet has given criminals a platform on which to grow and proliferate. As a result of the abstract nature of the Internet, it is easy for these criminals to go unpunished. Moreover, many who use the Internet are not aware of such threats; therefore they may themselves be at risk, together with businesses and governmental assets and infrastructure. In view of this, there is a need for cyber security awareness and education initiatives that will promote users who are well versed in the risks associated with the Internet. In this context, it is the role of the government to empower all levels of society by providing the necessary knowledge and expertise to act securely online. However, there is currently a definite lack in South Africa (SA) in this regard, as there are currently no government-led cyber security awareness and education initiatives. The primary research objective of this study, therefore, is to propose a cyber security awareness and education framework for SA that will assist in creating a cyber secure culture in SA among all of its users of the Internet.

- Description: Cloud computing is a relatively immature computing paradigm that could significantly benefit users. Cloud computing solutions are often associated with potential benefits such as cost reduction, less administrative hassle, flexibility and scalability. For organisations to realize such potential benefits, cloud computing solutions need to be chosen, implemented, managed and governed in a way that is secure, compliant with internal and external requirements and indicative of due diligence. This can be a challenge, given the many concerns and risks commonly associated with cloud computing solutions. One cloud computing solution that is being widely adopted around the world is cloud-based email. One of the foremost adopters of this cloud computing solution is higher education institutions. These higher education institutions stand to benefit greatly from using such services. Cloud-based email can be provisioned to staff and students at these institutions for free. Additionally, cloud service providers (CSPs) are able to provide a better email service than some higher education institutions would be able to provide if they were required to do so in-house. CSPs often provide larger inboxes and many extra services with cloud-based email. Cloud-based email is, therefore, clearly an example of a cloud computing solution that has the potential to benefit organisations. There are however, risks and challenges associated with the use of this cloud computing solution. Two of these challenges relate to ensuring conformance to internal and external (legal, regulatory and contractual obligations) requirements and to providing a mechanism of assuring that cloud-based email related activities are sound. The lack of structured guidelines for assuring the conformance of cloud-based email is putting this service at risk at higher education institutions in South Africa. This work addresses this problem by promoting a best practice based approach to assuring the conformance of cloud-based email at higher education institutions. To accomplish this, components of applicable standards and best practice guidelines for IT governance, IT assurance and IT conformance are used to construct a framework for assuring the conformance of cloud-based email. The framework is designed and verified using sound design science principles. The utility and value of the framework has been demonstrated at a higher education institution in South Africa. This framework can be used to assist higher education institutions to demonstrate due diligence in assuring that they conform to legal and best practice requirements for the management and governance of cloud-based email. This is a significant contribution in the relatively new field of cloud computing governance.

- Description: In the South African Social Security Agency (SASSA) Annual Report of 2011/2012 it is stated that there were more than 15 million social grants paid out to needy beneficiaries of which 10 927 731 were Child Support Grants. A major challenge that is continually being addressed is the management and administration of these grants. In particular, the focus is on service delivery and zero tolerance to fraud and corruption. SASSA has made various attempts to address these issues, such as the rollout of biometric smart cards in 2012. This research endeavour attempts to discover whether a framework can be designed where necessary factors are taken into consideration to provide for an efficient social grant application and delivery process that uses biometrics. The framework aims to suggest improvements in the use of biometrics for the social grants. Seeing that biometrics in this case is used as a technology to improve a system involving humans, this study followed a Design Science approach and made use of a case study to collect the data required for the study. Literature studies reviewed the fields of social grants and biometrics. The challenges and lessons learnt from current implementations of social grants and biometrics within the South African context and further abroad were also relevant for the study. The framework that resulted from the above was evaluated for validity and applicability after which a modified framework is presented. The research concludes with specific implementation guidelines as well as areas for future research.

- Description: In recent years the field of Business Process Modelling (BPM) has gained increasing attention from both the business and research communities. One of the primary drivers for BPM is the improved understanding of Business Processes (BPs) and the competitive advantage gained over competitors. In addition, BPM can improve communication in an organisation and facilitate increased support for change management. BPM is a collaborative activity that needs to be carried out in a team environment, and Collaborative Business Process Modelling (CBPM) promotes improved readability, accuracy and quality of process models as well as a reduced workload for modellers. In spite of the increased popularity of CBPM, there is limited research related to the collaborative nature of the modelling tasks performed by modellers and specifically to the synchronisation of shared process models. In addition, tools and techniques to support CBPM do not support this synchronisation effectively or efficiently. This study proposes a conceptual framework for CBPM using touch technologies in a colocated collaborative environment. The main research problem addressed by this study is that modellers experience difficulties conducting BPM activities in a co-located collaborative environment. In order to address the research problem and clarify and elaborate on the problems of CBPM, a two-fold approach was undertaken. Firstly, after an in-depth literature review, a BPM survey was designed and then sent to modellers in South African Information Technology (IT) consulting companies in order to provide a more in-depth understanding of the status and challenges of CBPM in IT consulting organisations. The results revealed that available BPM software do not adequately cater for CBPM and software tools do not enforce versioning and synchronisation. In addition, hardware constraints were reported as well as problems with integrating different parts of the process model that the modellers were working on. The results of the survey also showed that the positive aspects of CBPM are that ideas could be shared and overall there is a better understanding of the BPs being modelled. The second part of the problem elaboration consisted of usability field studies with participants from both education and industry using a traditional popular BPM software tool, Enterprise Architect (EA). Whilst several benefits of CBPM were confirmed, several challenges were encountered, particularly with regard to the integration and synchronisation of models. To overcome the problems of CBPM, a framework was developed that allows for co-located CBPM using tablet PCs. The framework includes a developed prototype of the BPMTouch software which runs on tablet PCs, as well as some theoretical aspects of CBPM. The BPMTouch software supports effective and efficient CBPM and the synchronisation of process models since it allows multiple modellers to work together on one BP model, with each modeller using his/her own tablet. If one modeller makes changes to the model, the changes are immediately reflected on the tablets of the other modellers since the changes to the model are updated in real time. Modellers cannot draw on the same model simultaneously, however, everyone can see what the active modeller (active participant with the green flag) is doing. Other participants can then become the active modeller and make changes to the model once the flag has been released and re-allocated. The results from the field studies, industry surveys and usability evaluations were all incorporated into the BPMTouch software tool design and into the aspects of CBPM in order to assist with the process of co-located CBPM using touch technologies. Usability evaluations were carried out in which industry and student participants used BPMTouch to create an integrated model and simultaneously and synchronously create a process model. The evaluations of the BPMTouch prototype revealed that participants prefer this system over traditional BPM software since the BPMTouch removes the need for post modelling integration. The theoretical contribution of the framework consists of aspects proposing that organisations should take the potential benefits and challenges of CBPM into consideration and address the Critical Success Factors (CSFs) before embarking on a CBPM project. These aspects can help with decisions relating to CBPM. The use of this framework can improve the quality of process models, reduce the workload of modellers and in this way increase the success rate of CBPM projects.

- Description: The concept of social media has grown rapidly in the last years. This can be attributed to the rate of adoption and the penetration of social media around the world. Currently, there is an estimate of over two billion people that are actively using social media. The increased usage of social media has changed the way people interact and communicate. Literature suggests that Internet-enabled social networks (relationship between or among individuals and groups) are developing faster than offline relationships. Previous studies have linked social media to the social network theories that define social relationships based on the actors, the ties that exist and the flow of resources among them. This is made possible by social networking sites and other Internet enabled services that allow friends to meet, connect and interact. Social media allow for individuals, groups or organisations to build their social network of friends and followers. It also facilitates the formation of communities with common interest. Social media facilitate the creation and exchange of content such as text messages, images, audio and video formats among individuals or communities that share a common interest or belong to the same social network. Social capital theorists suggest that the ties that exist in social interaction like on social media have the ability to create benefit for the actors in the networks. This provides the foundation to study the benefits that individuals and organisations can obtain from social media. The opportunity to target and communicate directly with the target market and potential customer qualifies social media as a valuable marketing tool and an important component of the integrated marketing communication. As a marketing communication tool, social media introduces a completely new paradigm into marketing communications. Therefore marketing professionals and academics are continuously seeking how to take advantage of social media for different industries. In the field of politics, the use of marketing concepts to engage voters and drive collective participation in political processes has become critical due to stiff competition. The use of social media for political campaigning and engagement could be beneficial, but politicians and political organisations are not taking full advantage of the concept. Previous studies show that organisations are aware of the opportunities that social media could provide for their organisations. However, they are reluctant because they are faced with the problems of lack of information on how to implement social media for business purposes. This treatise investigates the approach and critical success factors for the use of social media for political campaigning and engagement. To evaluate the conceptual framework that was suggested by this study based on the literature review and case studies, an empirical study was conducted among the members of the Democratic Alliance in the Eastern Cape. A survey was conducted among the members of the Democratic Alliance in the Eastern Cape using a questionnaire and 92 responses were received. The questionnaire measured the respondents’ social media usage, level of political engagement, perception on the use of social media for political engagement and the level of political activities on social media. Also, hypotheses were tested to examine the assumption that there might be an association between the respondents’ gender, population group and level of political activities on social media. The findings of this study indicate that a structured approach, a strong emphasis of engaging followers socially and micro-targeting are critical to effective implementation of social media for political campaigning and engagement. Other factors include the direct involvement of leadership, listening and encouragement of user generated contents. This study concludes that political organisations can use social media to establish multi-levelled social networks that provide access to their target audience and also reach potential audience through their friends. This social connectedness can then be translated into political social capital for campaign and engagement purposes.

- Description: The concept of social media has grown rapidly in the last years. This can be attributed to the rate of adoption and the penetration of social media around the world. Currently, there is an estimate of over two billion people that are actively using social media. The increased usage of social media has changed the way people interact and communicate. Literature suggests that Internet-enabled social networks (relationship between or among individuals and groups) are developing faster than offline relationships. Previous studies have linked social media to the social network theories that define social relationships based on the actors, the ties that exist and the flow of resources among them. This is made possible by social networking sites and other Internet enabled services that allow friends to meet, connect and interact. Social media allow for individuals, groups or organisations to build their social network of friends and followers. It also facilitates the formation of communities with common interest. Social media facilitate the creation and exchange of content such as text messages, images, audio and video formats among individuals or communities that share a common interest or belong to the same social network. Social capital theorists suggest that the ties that exist in social interaction like on social media have the ability to create benefit for the actors in the networks. This provides the foundation to study the benefits that individuals and organisations can obtain from social media. The opportunity to target and communicate directly with the target market and potential customer qualifies social media as a valuable marketing tool and an important component of the integrated marketing communication. As a marketing communication tool, social media introduces a completely new paradigm into marketing communications. Therefore marketing professionals and academics are continuously seeking how to take advantage of social media for different industries. In the field of politics, the use of marketing concepts to engage voters and drive collective participation in political processes has become critical due to stiff competition. The use of social media for political campaigning and engagement could be beneficial, but politicians and political organisations are not taking full advantage of the concept.

- Description: We live today in the information age with users being able to access and share information freely by using both personal computers and their handheld devices. This, in turn, has been made possible by the Internet. However, this poses security risks as attempts are made to use this same environment in order to compromise the confidentiality, integrity and availability of information. Accordingly, there is an urgent need for users and organisations to protect their information resources from agents posing a security threat. Organisations typically spend large amounts of money as well as dedicating resources to improve their technological defences against general security threats. However, the agents posing these threats are adopting social engineering techniques in order to bypass the technical measures which organisations are putting in place. These social engineering techniques are often effective because they target human behaviour, something which the majority of researchers believe is a far easier alternative than hacking information systems. As such, phishing effectively makes use of a combination of social engineering techniques which involve crafty technical emails and website designs which gain the trust of their victims. Within an organisational context, there are a number of areas which phishers exploit. These areas include human factors, organisational aspects and technological controls. Ironically, these same areas serve simultaneously as security measures against phishing attacks. However, each of these three areas mentioned above are characterised by gaps which arise as a result of human involvement. As a result, the current approach to mitigating phishing threats comprises a single-layer defence model only. However, this study proposes a holistic model which integrates each of these three areas by strengthening the human element in each of these areas by means of a security awareness, training and education programme.

- Description: The effect of the inclusion of sexual behaviour, particularly three sexual orientation classes, on the transmission dynamics of HPV and cervical cancer incidence was investigated. A comprehensive literature review of mathematical models of HPV transmission and the natural history of cervical cancer was concluded. A mathematical model using ordinary differential equations was developed, which incorporated the three sexual orientation classes, and a sexual mixing algorithm for modelling the transmission dynamics. Reproduction numbers, determined through a simplified version of the developed model, indicated that the bisexual population could form a bridge between the heterosexual and homosexual population. The level of interaction is determined by the selection preferences of a bisexual individual to form a partnership with an individual of the same or opposite sex. The model was simulated, with parameters based on a South African population and HPV type 16/18, to investigate the effects of HIV status, sexual orientation and various vaccination strategies on HPV transmission and cervical cancer incidence. The results indicated that HIV status is a significant factor when determining cervical cancer incidence. The results regarding vaccination strategies agreed with results from the literature review with a two sex before sexual debut and catch up program the most effective, noting that with increased vaccination coverage of females the marginal impact on cervical cancer incidence of this approach diminished.

- Description: Mentoring is a powerful developmental tool that can be utilised in organisations to enable learnerships to learn various skills – hard and soft – that will enable them to become more equipped for the workplace. The hard skills refer to technical competencies, e.g. computer literacy, and soft skills refer to competencies such as interpersonal skills, communication skills, work etiquette, etc. Mentoring is no quick fix to filling all the gaps within a learnership, but it can add significant value to have a formal mentoring strategy within organisations to transfer much needed skills and competencies. The literature on mentoring provides many examples of possible strategies, and in this research project, the competencies of both mentor and mentee were highlighted, together with the advantages, disadvantages, myths and challenges in formal mentoring strategies. The process of developing a mentoring strategy is not complex, but requires support and involvement from various stakeholders to ensure the sustained success of a mentoring strategy. The different models of mentoring strategies in the literature review provided a framework for the researcher to develop a mentoring strategy that was tested through the completion of questionnaires sent to organisations that employ learnerships. The research study rated the responses of the respondents on the suggested model and various steps to be followed in the process. The research study concluded with a formal mentoring strategy or model that can be used within organisations that employ learnerships.

- Description: Since the beginning of the millennium there has been a drive by organisations to achieve more with fewer resources. This has been heightened further by the global financial recession which has both direct and indirect effects on South Africa. Employee engagement has now become a critical business issue as the economic landscape becomes increasingly turbulent and organisations need coherent strategies to maintain their competitive advantages. Employee engagement is a business management concept that is particularly relevant to organisations that leverage off human capital and involves the maximising of individual commitment to and satisfaction with work. When the current healthcare environment is taken into consideration, with its dire shortage of medical doctors, a human resources scheme that has employee engagement at its heart must be considered an imperative by medical organisations. Upon embarking on the research into the topic it became evident that there was a scarcity of investigations into employee engagement as it applied to physicians. The purpose of this treatise, then, is to examine the key drivers of employee engagement in emergency medicine doctors and develop an engagement model that can be used by organisations to enhance this positive psychological state for their good, the good of the medical doctor and, in due course, for their patients. In order to achieve this goal a thorough literature review was performed which drew on both academic and practitioner sources of information into the concepts of employee, knowledge worker and physician engagement. This led to the development of a hypothesised model which was tested using rigorous measures incorporating questionnaire-style, quantitative data collection and statistical analysis. The results of the research show that communication; work-life; company alignment; growth and development; recognition and reward; management support; autonomy; and mission and purpose are all closely associated with the construct of employee engagement. Work-life and company alignment, in particular, were shown to have direct positive associations with the concept and are postulated to be key areas for emergency medical organisations to focus their attentions in the quest for engaged and motivated doctors. Ultimately, employee engagement is shown to be valuable, measurable and actionable. The devised model for employee engagement in emergency medical doctors can be utilised in the harnessing of physicians hearts and minds to the work that they love doing and the organisations that they love doing it for. This is a win-win result for all of the important stakeholders of healthcare in South Africa.

- Description: New innovative products are being designed while the user interface of existing products is constantly being revamped to give them a new look. All this is an effort to bring a satisfactory interacting experience for the user. However, in most cases users do not feel that they experience that benefit. The introduction of a new product, or the enhancement of the functionality and user interface of an existing product, often faces criticism and brings resistance to the acceptance and usage of the product by the users. Therefore, the change in user interface or introduction of new products does not only affect the business processes but also the lifestyles of the users, as well as their overall user experience. One of the most important components for the success of any product is a positive user experience. User experience refers to the subjective feeling of the user that results from their interaction or intention to interact with a product in order to perform a specific task in a specific environment. When the user interface and functionality of a product match the expectations of the users and make the users effective and efficient, feel safe and attain some level of self-worth from using or possessing the product, their interaction with the product becomes more satisfactory. User experience practitioners are in agreement that a change to the user interface influences the user experience of the people when interacting with the product; hence it affects change in the user experience of the people. A vast body of literature exists on the methods for evaluating user experience as well as on the principles that are aimed at guiding the design of products for a positive user experience. However, there is a lack of a means to manage this change in user experience that results from the changes in the features of the user interface or the product functionalities. This inadequacy opens up the potential for integrating change management principles in order to manage user experience. However, existing change management principles do not address the user experience aspects when managing change. Following the above premise, this study focused on the development of a model for managing user experience: the User Experience Management Model (UXM2). The UXM2 infers its components from the disciplines of user experience and change management. Its uniqueness is seated in its people-centred approach that aims to effect a free-will change in the individuals towards a long-term positive user experience. The proposed model further aims to promote the voluntary acceptance of a product, which is contrary to the mandatory change that is guided by the policies of the organization, as discussed in the study. The UXM2 was developed from a thorough argumentation of literature on user experience and change management. The components that were required for development of the model were identified from literature, and were evaluated for their relevance by means of academic publications in subject domain international conferences. The academic publications underwent double-blind peer review with subject domain experts. The model was evaluated for its relevance and potential applicability through interviews and discussions with subject domain experts. The subject domain experts consist of user experience practitioners and academic professionals in the domain of HCI. The subject domain experts also evaluated the model by means of an evaluation tool comprising of a Likert scale rating of the proposed components and related activities for managing user experience. The target users of the UXM2 are user experience practitioners and product developers who aim to promote a sustainable long-term positive user experience for the people interacting with their products. The UXM2 is aimed at being used for the design of products that are meant for institutional use, personal use, mandatory use and optional use. It is believed that adoption of the UXM2 will promote acceptance of the product by users, with an associated sustainable positive long-term user experience.

- Description: University sustainability is a field of research that has been gaining increased interest in recent years. The reduction of environmental impact has become a strategic objective of universities globally. Universities have been prompted to take necessary action to ensure that their environmental impact is at a minimum. The environmental component of sustainability deals with the current conservation of the earth’s natural resources so that future generations can also have access to them. Human beings, due to their increasing needs, are accountable for the exploitation of natural resources. They are regarded as the main contributors to imbalances in the natural systems. Environmental concerns such as global warming, deforestations, disposal of wastes, and ozone reduction are the outcomes of the damage caused by humans on the environment. The aim of environmental education is to acquire remediation of the environment by making individuals aware of the environment and by educating them about how to live a more sustainable lifestyle. Environmental awareness is perceived as knowledge of the factors that affect the environment and having sensitivity towards the environment. Higher Education Institutions (HEIs) bear the responsibility of educating individuals about environmental issues since they provide education to future leaders in society who may have an influence on future conditions in the environment. Social media are capable of delivering information to a large spectrum of audiences at a low cost. The Pew Internet American Life Project reported that the number of adults who utilise social media has increased by 57 percent from 2005 to 2011. Several environmental activist organisations utilise social media to carry out environmental awareness campaigns. In this study two environmental awareness campaigns which were powered by social media were conducted to improve environmental awareness of individuals in a higher education environment. A Social media Model for ENvironmental Awareness (SMENA) was developed to facilitate the environmental awareness campaigns. The SMENA includes a website, social media as well as theoretical guidelines for creating environmental awareness campaigns, and for using social media for environmental awareness campaigns. A case study at the Nelson Mandela Metropolitan University (NMMU) was used to empirically evaluate SMENA. Students at the Department of Computer Sciences of NMMU were exposed to information about environmental issues through social media with the intention of improving their environmental knowledge and awareness. The SMENA website usability was rated positively and students enjoyed the blogs and information distributed by means of social media. The results of the study intervention were positive and showed that social media can be used to improve the environmental knowledge of students. This study provides a valuable contribution to both the field of environmental education and social media usage and acceptance. The guidelines and requirements for using social media to improve environmental awareness provided in this study can be used to assist educators and university management with addressing the problems of reducing environmental impact.
