- Description: The IPv6 increased address pool presents changes in resource impact to the Enterprise that, if not adequately addressed, can change risks that are locally significant in IPv4 to risks that can impact the Enterprise in its entirety. The expected conclusion is that the IPv6 environment will impose significant changes in the Enterprise environment - which may negatively impact organisational security if the IPv6 nuances are not adequately addressed. This thesis reviews the risks related to the operation of enterprise networks with the introduction of IPv6. The global trends are discussed to provide insight and background to the IPv6 research space. Analysing the current state of readiness in enterprise networks, quantifies the value of developing this thesis. The base controls that should be deployed in enterprise networks to prevent the abuse of IPv6 through tunnelling and the protection of the enterprise access layer are discussed. A series of case studies are presented which identify and analyse the impact of certain changes in the IPv6 protocol on the enterprise networks. The case studies also identify mitigation techniques to reduce risk.

- Description: As a result of the different tax systems adopted by countries, foreign-sourced income earned by taxpayers may be subject to double taxation. This may therefore impede cross-border trade and investment. Double taxation relief is provided unilaterally, in terms of a country’s domestic laws or bilaterally in terms of Double Taxation Agreements. South African residents earning income from the Democratic Republic of Congo may be subject to tax in both countries. To eliminate such double taxation the South African Income Tax Act, No 58 of 1962, provides for unilateral relief from double taxation in the form of exemptions, rebates and deductions. The double tax agreement between South Africa and the Democratic Republic of the Congo came into effect recently and double taxation relief for South African residents is now also available in terms of tax treaty law. The objective of the research was to determine whether the combination of the unilateral measures and the double tax agreement provide relief in respect of all types of income earned by South African residents in the Democratic Republic of the Congo. It was concluded that the double tax agreement, together with the unilateral relief provided for in the Income Tax Act will grant relief for all types of income earned by South African residents in the Democratic Republic of the Congo.

- Description: Stories have the ability to evoke feelings and emotions in humans and have since been used by brands as part of corporate communication, communicating their vision and values. However, the growing technological trends have not only shifted the platforms for communication but also changed the techniques of communication as audiences on social media expect two-way communication instead of the traditionally used one-way communication. This is exacerbated by the power of word-of-mouth on social media as well as the presence of digital natives who are increasingly visual in their nderstanding and are immersed in their lives online. This has given rise to the use of visual storytelling as a corporate communication strategy as brands are using it to connect, transmit and receive messages from their audiences. This study examines the ways in which South African brands are making use of visual storytelling on social media and aims to determine the extent to which the use of visual storytelling promotes brand-audience engagement. The study is based on the philosophical assumptions of the Visual Rhetoric framework, which is concerned with the symbolic processes by which images perform communication. The hermeneutic – interpretive research method design is applied to justify knowledge produced by this study. A content analysis of six social media pages was conducted, looking at the visual content posted as well as interpretation of comments and interactions by fans of the selected brand pages. Overall, South African brands make use of visual storytelling to promote brand-audience engagement but they are not utilising the communication strategy to its fullest extent.

- Description: Due to innovation, Information Technology (IT) is changing all the time. One of the fast growing IT innovations is cloud computing. The phenomenon of cloud computing has changed the way that business consumes IT and in particular Enterprise Resource Planning (ERP) systems. This phenomenon has led to a need for research in the field of cloud ERP systems. A review of the literature revealed a gap in research related to cloud ERP systems and particularly to the adoption of these systems in South African companies. Only a few studies have been done regarding the adoption of cloud computing in South Africa, and the extent of adoption of cloud ERP systems in South Africa is not known. This study set out to answer the research question “What is the extent of understanding and adoption of ERP system in South African companies?” The study will be useful to the ERP industry in understanding the level of adoption of and perceptions about cloud ERP systems by South African companies. In order to answer the research question a survey research strategy was adopted and was of an exploratory nature. The sample was composed of IT professionals and line managers in South African companies. Questionnaires were sent via web link and 41 complete responses were obtained. The results showed that the respondents had a good understanding of the advantages/benefits of cloud ERP systems. However, a lack of clear understanding of the disadvantages/drawbacks of cloud ERP systems was evident in the research data which could lead to non-adoption of cloud ERP systems. Adoption of cloud ERP systems was highest in the engineering, manufacturing and IT sector. It was evident that IaaS and PaaS have not been adopted at all. The majority of the companies (60 percent) that had adopted cloud ERP systems were SMEs. This is in line with international studies that show that SMEs are driving the change in IT innovation such as cloud ERP systems.

- Description: The problem investigated by the researcher is that of alignment of the Integrated Development Plan of Amathole District Municipality with those of the selected local municipalities under its area of jurisdiction. The aim of the study was to investigate the extent to which there is or there is no alignment amongst these. The study articulated the background of municipal planning in terms of the provisions of enabling pieces of legislation. It further provided a conceptual and theoretical framework for integrated development planning within the local government sphere. The literature raised critical issues revolving around the importance of the district municipality in achieving congruence of development plans of the district and those of its local municipalities. The data was collected using a combination of qualitative and quantitative approaches, to realize the objectives of the research study. The methods used to collect data included, document study, interviews, observation, and questionnaires. The study findings showed that, there is a lot of planning efforts put into achieving alignment of the IDPs of the District and local municipalities under it. The study concluded that, with this good planning by the district municipality a correlating hands on support and monitoring by the municipal unit needs to be firmed up. The recommendations are an evidence that there are processes deliberately put in place by the District municipality to ensure alignment between the IDP of the District and those of its Local Municipalities.

- Description: Publisher version , Traditional approaches to monitoring aquatic systems are often limited by the need for data collection which often is time-consuming, expensive and non-continuous. The aim of the study was to map the spatio-temporal chlorophyll-a concentration changes in Malilangwe Reservoir, Zimbabwe as an indicator of phytoplankton biomass and trophic state when the reservoir was full (year 2000) and at its lowest capacity (year 2011), using readily available Landsat multispectral images. Medium-spatial resolution (30 m) Landsat multispectral Thematic Mapper TM 5 and ETM+ images for May to December 1999–2000 and 2010–2011 were used to derive chlorophyll-a concentrations. In situ measured chlorophyll-a and total suspended solids (TSS) concentrations for 2011 were employed to validate the Landsat chlorophyll-a and TSS estimates. The study results indicate that Landsat-derived chlorophyll-a and TSS estimates were comparable with field measurements. There was a considerable wet vs. dry season differences in total chlorophyll-a concentration, Secchi disc depth, TSS and turbidity within the reservoir. Using Permutational multivariate analyses of variance (PERMANOVA) analysis, there were significant differences (p < 0.0001) for chlorophyll-a concentration among sites, months and years whereas TSS was significant during the study months (p < 0.05). A strong positive significant correlation among both predicted TSS vs. chlorophyll-a and measured vs. predicted chlorophyll-a and TSS concentrations as well as an inverse relationship between reservoir chlorophyll-a concentrations and water level were found (p < 0.001 in all cases). In conclusion, total chlorophyll-a concentration in Malilangwe Reservoir was successfully derived from Landsat remote sensing data suggesting that the Landsat sensor is suitable for real-time monitoring over relatively short timescales and for small reservoirs. Satellite data can allow for surveying of chlorophyll-a concentration in aquatic ecosystems, thus, providing invaluable data in data scarce (limited on site ground measurements) environments.

- Description: The South African Constitution of 1996, as amended, provides for three spheres of Government, namely National, Provincial and Local Government. The local sphere of government is mandated to provide developmental and accountable local government and to ensure the provision of basic services to communities in a sustainable manner. The Department of Provincial and Local Government Community-Based Workbook and Guide provided that local government legislation has been put in a place to enable South Africa to constructively work towards providing basic services and improving the social and economic lives of citizens. As local government is the sphere of government where delivery takes place at community level, it is important to ensure and secure the support and participation of communities. It is critical to mention that local government faces many challenges in providing services that will contribute to developing a peaceful, stable and healthy environment. In adherence to Local Government legislation, which includes, inter alia, the Municipal Systems Act and the Municipal Finance Management Act, the local authorities are required to provide systems and processes to enable public participation processes in the affairs of the municipalities. This requirement is mandatory to ensure that citizens contribute by making input in the planning of the municipality. Amathole District Municipality adopted a Public Participation and Petitions Policy to ensure that citizens participate in the activities of the municipality. The main purpose of this study was to establish whether those structures are effective and whether the municipality, in its planning processes, considered the views and input of the communities. The study investigated the extent of community participation in municipal planning and performance and also investigated the effectiveness of ADM community participation strategies. Quantitative research methods were used to collect data for the study. The research questionnaire covered a wide range of council related activities ranging from knowledge of local government legislation relating to public participation, understanding of public participation processes by councillors, compliance of the municipality with public participation processes and related legislation and feedback to communities on the input they make to the Integrated Development Plan (IDP) and the Budget planning processes. The questionnaires were administered to all Councillors within the municipality to ensure that all municipal programmes were covered, and the Executive Mayor, Council Speaker who ensures that council resolutions are implemented and the Chief Whip of Council, who is responsible for the welfare of all political parties in Council. There was also the inclusion of the Chairperson of the Municipal Public Accounts Committee who is responsible for oversight and monitoring the performance of the Executive. The sample group was carefully chosen to represent a wide range of councillors who serve in the ADM Council. The positive response rate therefore provided an acceptable scientific basis for analysis and objectivity to the study.

- Description: E-tolling was recently implemented on roads in Gauteng, South Africa. This gave rise to a great deal of protest by road users and a court battle between the South African National Roads Agency (SANRAL) and the Opposition to Urban Tolling Alliance, a body representing road users. The e-tolling system was criticised at various levels and on numerous grounds, some financial and others appearing to be emotional. This thesis attempted to analyse the various grounds for objection against the system, the main goal of the research being to analyse e-tolling in Gauteng to ascertain whether or not the introduction of e-tolling was justified or whether an alternative method of taxation to pay for the upgrading of Gauteng roads would have been more cost-effective. Secondary data in the form of documents from multiple sources was used in the analysis, including an Economic Impact Assessment that was one of the key inputs into the decision to introduce e-tolling. It was found that there are multiple problems plaguing the e-toll system and e-tolling is not the most cost-effective taxation method of paying for Gauteng roads. Using a fuel levy or general tax revenue available to the National Treasury were both found to be more cost-effective methods as they would have achieved the same result (repairing and upgrading specific Gauteng roads), at a cost of R20,0913 billion less than e-tolling. It was suggested that the best taxation method/s to pay for the roads would have been using a fuel levy and general tax revenue as the primary funding methods, with vehicle licensing fees and long distance toll roads as secondary methods to aid the primary methods.

This thesis attempted to analyse the various grounds for objection against the system, the main goal of the research being to analyse e-tolling in Gauteng to ascertain whether or not the introduction of e-tolling was justified or whether an alternative method of taxation to pay for the upgrading of Gauteng roads would have been more cost-effective. Secondary data in the form of documents from multiple sources was used in the analysis, including an Economic Impact Assessment that was one of the key inputs into the decision to introduce e-tolling. It was found that there are multiple problems plaguing the e-toll system and e-tolling is not the most cost-effective taxation method of paying for Gauteng roads. Using a fuel levy or general tax revenue available to the National Treasury were both found to be more cost-effective methods as they would have achieved the same result (repairing and upgrading specific Gauteng roads), at a cost of R20,0913 billion less than e-tolling. It was suggested that the best taxation method/s to pay for the roads would have been using a fuel levy and general tax revenue as the primary funding methods, with vehicle licensing fees and long distance toll roads as secondary methods to aid the primary methods.

- Description: The aim of this study was to assess the perceptions of employees towards performance appraisal (PA) with special reference to Statistics South Africa (Stats SA) in the Eastern Cape Province. The research objectives included, inter alia; assessing employee perceptions towards effective administration of PAs, assessing perceptions of employees towards the fairness of the PA process, identifying the motivating factors for the improvement of employee performance and identifying the challenges facing the PA process. To achieve these objectives, a mixed methods research approach was used. The mixed methods approach utilised a combination of qualitative and quantitative research methods. The sample was selected using a purposive sampling technique whereby employees with tenure of at least one year and above in the organisation were targeted. Employees who met this criterion were considered to have reasonable understanding of the PA process and practice of Stats SA. The literature review for this study revealed that employee perceptions towards the PA process are crucial in determining the long-term effectiveness of the PA system. It also emerged that the appraisal process can become a source of extreme dissatisfaction when employees believe the system is biased, political or irrelevant. The findings revealed that 65% of employees perceive the administration of PAs as ineffective whilst 35% of employees consider PA administration at Stats SA to be effective. Ineffective administration of PA was further confirmed by 81% of managers who stated that the evaluation process is not integrated effectively with other human resource (HR) processes at Stats SA. Furthermore, 58% of employees are not satisfied with the fairness of the appraisal process. These negative perceptions towards the PA process were reaffirmed by 88% of managers who also indicated that they are not satisfied with the fairness of the PA process. The research showed that the motivating factors for improving job performance include allocation of adequate resources, training, recognition and appreciation, improved communication along with a good working relationship as well as a performance bonus. According to the research findings, 45% of employees consider the current Performance Management System (PMS) at Stats SA as having a motivational effect on staff to improve their performance whilst 42% held a contrary view and 13% were unsure. The respondents identified the challenges facing the PA process at Stats SA, namely; favouritism and bias, dropping of scores by the provincial moderating committee without clarifying the criteria followed, supervisors scoring themselves high whilst scoring those who are doing the work on the ground low, failure by HR to provide guidance and training on performance management (PM), failure by supervisors to provide performance feedback after the appraisal process, failure to comply with PM policies and procedures, the ambiguous role of the provincial moderating committee, and a narrow focus on monetary reward. The findings suggest that the effectiveness of a Performance Management System (PMS) such as the Performance Appraisal System depends on the achievement of various purposes and objectives for which the PMS is designed and implemented in an organisation. This requires managers and supervisors to be fully involved and committed in the day to day management of employee performance in order to ensure that the strategic goals of the organisation are fully achieved.

- Description: The study critically examined the implementation of Public Accountability strategies and mechanisms: A case of Buffalo City Municipality. The problem statement gave emphases on the multiple cases drawn from stats reflected in domestic surveys that shows how corruption and maladministration have impacted the province negatively as well as the extreme poverty lines that dominate the communities in the republic and also the province. The New Public Management Theory was used to interpret the manner in which the participants were expected to give their views on leadership and accountability among others key issues. The objectives of the study were to; To assess the mechanisms implemented by Buffalo City Municipality., To explore the challenges affecting public accountability enforcement mechanisms in Buffalo City Municipality towards eradicating corruption, Determine the manner through which the Buffalo City Municipality can adopt tried and tested mechanism from Regional, national & international case studies on how to effective enforce public accountability for the sustainable management and curbing of corruption for effective and efficient service delivery and to recommend new mechanisms which Buffalo City Municipality can utilise in enforcing public accountability towards eradicating corruption in its institutions in order to encourage sustainable community development through service delivery. The study adopted a case study approach based on a mixed method paradigm where data was collected through a questionnaire, interviews and document analysis. Case studies are normally associated with qualitative research, but can also be used as a method of inquiry employing a positivist epistemology and ontology. A total sample of 50 participants was chosen through a non-probability sampling technique. The major findings of the study reflected that there is a huge break in communication between government and the citizens in the locality while also establishing that the mechanisms currently being used were only as good as the factors influencing their implementation among other issues.

- Description: The Office of the Auditor -General’s role is by no means minor, for it plays a major role in curbing corruption and acts as a ‘’watchdog’’ of the nation over public funds. Amidst high mismanagement and misuse of public resources, as well as corruption, especially in developing countries, the major question one asks is how effective the Auditor -General can be in ensuring good governance within state departments so as to improve service delivery. The gaps between approved budgets and the realisation of policy and development goals stand among key governance challenges in many developing countries. Supreme Audit Institutions (SAIs) play an important role in holding governments to account. However, many SAIs including AGSA face serious challenges when trying to evaluate the expenditures and performance of government agencies. Therefore this study suggests that more resources should be invested in the office of the AG so as to allow it to carry out its duties without impediments. Good governance and public finance accountability is becoming increasingly important in the public sector. One means of effecting good governance and accountability is through auditing. For this reason the Office of the Auditor-General through the Constitution of the Republic of South Africa 1996 (Act 108 of 1996 section 216 (1)) was established to facilitate and encourage good governance and effective accountability through auditing.

- Description: Rotenone, a naturally occurring ketone, is widely employed for the management of invasive fish species. The use of rotenone poses serious challenges to conservation practitioners due to its impacts on non-target organisms including amphibians and macroinvertebrates. Using laboratory studies, we investigated the effects of different rotenone concentrations (0, 12.5, 25, 37.5, 50, 100 μg L-1) on selected invertebrate groups; Aeshnidae, Belostomatids, Decapods, Ephemeroptera, Pulmonata and zooplankton over a period of 18 hours. Based on field observations and body size, we hypothesized that Ephemeropterans and zooplank- ton would be more susceptible to rote none than Decapods, Belostomatids and snails. Experimental results supported this hypothesis and mortality and behaviour effects varied considerably between taxa, ranging from no effect (crab Potamonuates sidneyi) to 100% mortality (Daphnia pulex and Paradiaptomus lamellatus). Planktonic invertebrates were par- ticularly sensitive to rotenone even at very low concentrations. Future research should investigate the recovery time of invertebrate communities after the application of rotenone and conduct field assessments assessing the longer term effects of rotenone exposure on the population dynamics of those less sensitive organisms.

- Description: This study looks at School Governing Bodies and its role and their effectiveness in school management. In terms of the South African Schools Act, all schools are now required to have School Government Bodies to compliment the formal school administrative structures. The research looks at how these bodies have functioned in a rural context. The empirical evidence, supported by other research evidence show that even though these bodies are sometimes dutifully constituted in schools, their functionality and effectiveness remains limited due to a number of reasons. This research study has shown that the ineffectiveness of SGBs in a rural context is attributed to that following key issues- firstly, there is limited knowledge of the functions of SGB, which can be traced to the lack of training on the body member; secondly, there is a inadequate framework in many public schools to engage with the SGBs; and finally there is a lack of school resources to make effective use of these bodies.

- Description: During the apartheid era black people were systematically excluded from all positions of influence in the state and civil society. The majority of senior posts in government were held by whites, in particular, white males. Women and people with disabilities were similarly disadvantaged and marginalised, particularly those from black communities. With the new post-apartheid dispensation, the democratic government took a conscious decision to change that situation. It is against this background that that the Employment Equity Act (EEA) was introduced in 1998. The two main aims of the Act are: to achieve employment equity by promoting equal opportunity and fair treatment in employment through the elimination of unfair discrimination; and to implement the affirmative action measures, to redress the disadvantages in employment experienced by designated groups in order to ensure their equitable representation in all occupational categories and levels in the workforce. The implement of EEA in the Eastern Cape Department of Transport (ECDOT) has so far not been very successful as the Department still has not managed to meet the set targets. According to their Employment Equity Plan (EEP), the senior management level (SMS) is still dominated by males. Although the situation is slightly better at the middle management level, it is still far from being ideal. The lower ranks are dominated by females. With regard to people with disabilities (PWDs) the Department is still far from meeting their 2% target. The purpose of this research was to determine if the ECDOT has been able to implement the dictates of the EEA. It aims to look at ways in which the EEA can best be implemented in order to ensure that the desired results are achieved. This study was prompted by the fact that the ECDOT has not managed to reach the EEA targets in hiring people with disabilities (PDWs) and elevating women to senior positions. The study explored the views of the employees of the Department regarding the implementation of EE. It was conducted using the quantitative approach. 90 employees were asked to respond to a structured questionnaire designed by the researcher. The findings of the study indicate that although in some areas the Department has been able to successfully implement EE, issues of racial equity, diversity, infrastructure conducive for people with disabilities, recruitment practices, and management commitment still need to be improved on. The study recommends, amongst others, that managers should provide leadership in the implementation process, more recruitment sources should be explored, suitable infrastructure must be provided, diversity issues must be addressed through workshops and training sessions, employee participation needs to be ensured, and that feedback must always be provided to EE beneficiaries in order to keep make sure they remain within the organisation and continue to improve.

- Description: During the apartheid era black people were systematically excluded from all positions of influence in the state and civil society. The majority of senior posts in government were held by whites, in particular, white males. Women and people with disabilities were similarly disadvantaged and marginalised, particularly those from black communities. With the new post-apartheid dispensation, the democratic government took a conscious decision to change that situation. It is against this background that that the Employment Equity Act (EEA) was introduced in 1998. The two main aims of the Act are: to achieve employment equity by promoting equal opportunity and fair treatment in employment through the elimination of unfair discrimination; and to implement the affirmative action measures, to redress the disadvantages in employment experienced by designated groups in order to ensure their equitable representation in all occupational categories and levels in the workforce. The implement of EEA in the Eastern Cape Department of Transport (ECDOT) has so far not been very successful as the Department still has not managed to meet the set targets. According to their Employment Equity Plan (EEP), the senior management level (SMS) is still dominated by males. Although the situation is slightly better at the middle management level, it is still far from being ideal. The lower ranks are dominated by females. With regard to people with disabilities (PWDs) the Department is still far from meeting their 2% target.

- Description: It is estimated by the World Health Organization (WHO) that by 2040 neurodegenerative disorders will collectively surpass cancer as the primary cause of death in industrialised countries (WHO,2006). Natural flora represents one of the most important therapeutic sources in modern drug discovery, however only a limited number of plant species have been screened for their neuroprotective value. The neuroprotective potential of eleven Algerian and two South African medicinal plant extracts were assessed in this study, aiming to identify promising candidates for future research. Neurodegenerative disorders such as Parkinson’s disease are characterised by distinct biochemical features, including protein misfolding/-aggregation, excessive oxidative stress and apoptotic cell death. As such, medicinal plant extracts were screened for biological properties directly relevant to neurodegeneration. The capacity to induce autophagy was also investigated as mounting evidence suggests that activation of this pathway may reduce abnormal protein aggregation and promote neuronal survival.

- Description: The study sought to assess the impact on learners‘ academic performance of the management of the quality of education in South African schools. The study was conducted in ten independent and ten public schools in Mthatha. The study elicited information for quantitative data from 60 school management team (SMT) members, 200 educators and 400 learners who were randomly sampled from the participating purposively sampled schools. Qualitative data and document analysis were used to triangulate quantitative findings. Data collected was coded and analysed thematically. Quantitative data were analysed with the aid of the SPSS version 22 and qualitative data were analysed through content analysis. Quantitative data were presented through a blend of both descriptive and inferential statistics using tables and graphs. The study found that school management teams (SMTs) and educators were more aware than learners that there are national and provincial legislation mandates that guide the management of quality in education. However, stakeholders were of the view that schools did not use relevant national, provincial and school-based policies and procedures to guide the provision and management of quality in education. It also emerged that learners did not conduct themselves in a manner that promoted the provision of quality education. Participants were, nevertheless agreeable on the indicators of high-quality education. SMTs and educators held stronger views than learners about schools having clear vision and mission statements (VMS) in place but neither were displayed for all to see nor were they well known to and supported by the ii SMTs, educators and learners, thus they were not implemented. The study also established that respondents were aware of the educator-centred, SMT-centred as well as learner-centred factors that affected the quality of education and that factors that promote high-quality education were largely absent in schools. Stakeholders also agreed about the effects of factors that affected the quality of education on learner performance such as poor training and development of educators. It emerged that there were positive SMT-centred factors such as promoting professional development of staff; educator-centred factors including maintaining exceptional lesson planning standards and presentation skills; learner-centred factors being geared towards school work while high parental involvement in school activities emerged as the overriding home-based factor noted to have a strong, positive impact on the provision of quality education and learner performance. It also emerged from the study that inter-alia, stakeholders viewed performance measurement and management as important and holding SMTs and educators accountable for poor school performance as an imperative measure for the provision of quality education. Recommendations for practice and for further research were made with a view to improving the management of the quality of education in schools. In light of that, a model for the management of the quality of education and learner performance was proposed.
