- Description: A comprehensive academic support at the public nursing college is important. Despite this, there is no such support in public nursing colleges in the Eastern Cape Province of South Africa. The aim of the study was to develop an academic support programme for students in order to improve their success in Higher Education. The study endeavoured to answer the following questions: What are the academic support needs of students at the public nursing college in the Eastern Cape of South Africa? What conceptual framework can be developed for the academic support programme of students? What academic support programme can be developed for students at the public nursing college? What guidelines can be developed for implementation of academic support programme of students? The objectives were: to describe academic support needs of students at the public nursing college in the eastern Cape Province of South Africa; to develop a conceptual framework for the academic support programme for students at the public nursing college in the Eastern Cape of South Africa; to develop an academic support programme for students at the public nursing college in the Eastern Cape in south Africa and lastly to describe guidelines for implementation and evaluation of the academic support programme. The research design used in this study was quantitative, qualitative, descriptive, evaluative, and theory generation. The study was conducted according to four phases. Phase one focussed on academic supports needs of the student. Phase two focussed on development of conceptual framework for the students at the public nursing college in Eastern Cape Province. Phase three focussed on the development of the academic support programme for the students, whereas phase four focussed on description of guidelines for implementation and evaluation of the academic support programme. The population of the study consisted of students undergoing training in a four-year programme at the Public Nursing College. The target population was the students in the same programme from level one to level four of training. The sampling technique used was a probability sampling with multi-stage and cluster sampling techniques being utilized. The total sample was n=333 participants. A quantitative self-developed questionnaire was used to collect empirical data. The questionnaire consisted of eight sections. Descriptive data was analysed using Statistic Package of Social Sciences (SPSS) version 24. Exploratory factor analysis was conducted on the descriptive data collected in phase one. Concept analysis and identification were done through the utilisation of exploratory factor analysis. The conceptual framework for the academic support programme was identified through the analysed factors. Fifteen factors were derived from the descriptive data. The conceptual framework of the academic support programme discussed in Chapter 5 was used also in the development of the academic support programme. It is in this chapter that assumptions, context, stakeholders, process, outcome, dynamics and, lastly, the recipient were discussed, along with a description of the programme. The programme was evaluated in accordance with the criteria for programme evaluation. The recommendations brought forward for the academic support programme were: The guidelines have to be tested for the implementation of the programme; benchmarking should be done to compare with other institutions of higher learning regarding their academic support programmes; an academic brochure regarding academic support must be available in the college and should be given to students on arrival as part of a package; and neutral researcher should conduct the same research in the same college.

- Description: Public service broadcasting in South Africa is the responsibility of the South African Broadcasting Corporation (SABC), which is the only national public service broadcaster mandated through the South African Broadcasting Act. Consequently, the SABC is meant to be a tool for information, entertainment and education that is accessible by all citizens, regardless of their social and economic status in the community. However, like all enterprises, the SABC requires a sustainable source of revenue to function effectively. It is of the utmost importance that the SABC has the necessary resources and stable source of revenue to fulfil its public service responsibilities, as a lack of proper resources and insufficient funds can hinder the provision of these services. The global economic crisis has put all public and private sector companies under financial pressure. The effect of this financial pressure was felt by the SABC and led to financial loss, subsequently posing a serious threat to the financial sustainability of the SABC. Given this situation, this study sought to develop a sustainable funding framework by identifying factors that influence the financial sustainability of the public broadcaster in South Africa and to provide alternative strategies for improving the financial sustainability of the public broadcaster in South Africa, which has thus far proved unsustainable and insecure. Past research has focused mainly on defining a public service broadcaster or a public mandate, or considered the future of public service broadcasters. In these past studies, researchers mostly debated the SABC funding challenges without attempting to develop a funding framework for the SABC. To achieve the objectives of this study a quantitative approach using a web-based distribution survey method was adopted to test the hypotheses. The participants were randomly selected in each provincial SABC office from the database of managers, unionised and non-unionised employees, as well as the database list of freelancers. A total of 432 participants, selected through a stratification sampling technique, were considered and 175 respondents completed the survey. However, after data clean-up only 168 respondents’ data was usable. Based on the analysis of various secondary sources, a theoretical framework regarding sustainable funding of the public broadcaster in South Africa was constructed. The proposed theoretical framework indicated that the intervening variable, which is sustainable funding, is possibly influenced by three independent variables namely, internal stakeholders, a competitive environment and the management of resources. The perceived outcomes (dependent variables) of a sustainably funded public broadcaster were identified as customer benefits and organisational performance. The computer programme STATISTICA was used for data analysis. Descriptive statistics was used to summarise the data of the respondents and allow easy interpretation by the researcher. Inferential statistical analysis was used to test for relationships between identified variables using a validity test, reliability test and correlation and regression analysis. The empirical results revealed that sustainable funding formed two separate intervening variables. These variables were renamed sustainable funding enabler and sustainable funding as part of management control. The dependent variable customer benefits and organisational performance also loaded onto a single factor and was renamed organisational outcomes. Given the results, it was determined that internal stakeholders, competitive environment and management of resources have a significant positive influence on the sustainable funding enabler for the public broadcaster. In turn, sustainable funding enabler had a significant positive influence on the organisational outcomes (customer benefits and performance). On the other hand, only the management of resources had a positive influence on sustainable funding as part of management control of the public broadcaster. Furthermore, sustainable funding as part of management control still had a significant positive influence on the organisational outcomes. The majority of the respondents agreed in their responses in relation to the variable items measuring sustainable funding as a part of management control and its influence to the organisational outcomes of the public broadcaster. In conclusion, sustainable funding of the public broadcaster is influenced by the identified variables, namely internal stakeholders, competitive environment and management of resources. In turn, sustainable funding has a positive influence on the organisational outcomes (customer benefits and performance). It is envisaged that the empirical evidence provided in this study will assist the SABC in understanding the factors influencing financial sustainability and thereby assist the organisation during strategy development and decision making. This study provides relevant and practical recommendations that will make the SABC financially sustainable. Finally, the objectives of this study were achieved and the research questions were answered. This study can also act as a foundation for other studies, thereby contributing to the body of knowledge.

- Description: Psychobiographical researchers methodically formulate life histories and interpret them by means of psychological theories. The research typically focuses on exemplary and completed lives. The cases that are studied are usually of individuals who are of particular interest to society as a result of excelling in their particular fields, be they to benefit or detriment of society. Temple Grandin was chosen for this study using purposive sampling as she meets the psychobiographical requirement of being an extraordinary individual. As an individual with autism Grandin faced many challenges growing up. Despite a difficult and absent beginning, Grandin developed into a stable and scientifically creative adult who contributes to society. She excels as an animal scientist and designer of humane livestock handling facilities and has an international reputation for her contribution to the livestock industry and animal welfare. The primary aim of this study is to describe and interpret the life of Temple Grandin through Erikson’s (1950/1973) theory of psychosocial development. A mixed method approach (Yin, 2006) was employed for the conduction of this study. The overarching data processing and analysis guidelines for this study were provided by Miles and Huberman (1994, 2002a, 2002b). The conduction of the processing and analysis of data was aided by Alexander’s (1988, 1990) method of asking the data questions as well as an integration of Yin’s (2014) time series analysis with Erikson’s (1950/1973) triple bookkeeping approach. This study contributes to the development of psychobiographical research in South Africa as well as to personality and developmental theory.

- Description: The importance of education cannot be overemphasized. Education has been identified as the most critical instrument for empowering individuals with the necessary knowledge and skills, which can give them access to productive employment. Also, the future of a country is based on the quality of education acquired by its citizens which helps in transforming it from pre-literate to contemporary nationhood. Many international treaties and initiatives in the world have made special provisions for education as a duty of every government which must be given to every citizen as of right, irrespective of gender or social class. Amongst these international initiatives is the Education for All (EFA) Goals, a time-bound global movement towards the provision of education for every one led by the United Nations Educational, Scientific and Cultural Organization (UNESCO). There are six goals in all. This study investigated one of the EFA goals, the goal 5. The aim of the study was a qualitative assessment of the achievement of gender equality goal under the Education for All (EFA) goals, a study of Lagos State, Nigeria. The theoretical framework of the study is informed by the Social Justice Theory and the Social Justice Praxis Theory. Scholarly works and literatures on girl-child education, gender and education, and gender balancing in education were reviewed. The study followed qualitative research approach which utilizes an interpretive research paradigm that provides a collective voice from the participants. The research area was purposively selected as Lagos State being a former capital of Nigeria and still the commercial nerve centre of the nation. Although it is the smallest state in Nigeria in term of size, it remains the most populous in the country with a projected population of 20,546,999 (13.5percent Nigeria’s total population). A sample of 16 participants were purposively selected because they were the officers directly in charge of the implementation government policies on education in the State. The data was collected through in-depth recorded interview sessions and secondary data were sourced through official documents downloaded online and from Lagos State Ministry of Education. Based on the thematic analysis of the data collected, the study found out that the State government had established policies and measures to provide qualitative education for all the citizens on a non-discriminatory basis. Thus, the goal of gender parity in terms of enrollment of boys and girls has been relatively achieved in the state. However, there were still some challenges of equality in the learning process and outcome. The study therefore recommends that schools should be made attractive and conducive as possible to assist the educational attainment of any student. This could be achieved by promoting positive values and attitudes towards education, all the stakeholders in the education sector must be involved in the business of running the school. There should also be a form of resourcing and expansion of the school facilities through the Public - Private Partnership in education.

- Description: This study was centred on the Agricultural Innovation System in the North West Province, South Africa as a response to climate change. The study developed during a time when Climate-Smart Agriculture emerged in policy and was developed as a strategic agricultural innovation process in response to changes in climate that increased food insecurity. The Agricultural Colleges embedded in the agricultural system realised that they were teaching students without a clear provision for climate change and therefore needed to initiate climate responsive innovations to comply with the Climate-Smart strategy that had been proposed by the provincial authorities. This provided the context for the study to track and support the innovation process of transitioning towards Climate-Smart responsive curriculum and learning practices within the system. A theoretical framework for the study was developed using a Cultural Historical Activity Theory perspective. This allowed the researcher to approach the research process as two case studies of innovation within the Agricultural Innovation System of the North West Province. The study developed as an iterative process of innovation support and tracking. At the early stages of the research process, data were generated through document analysis and a survey completed by the research participants at the preliminary consultative workshop. The contextual data allowed the researcher to begin to develop a clear contextual profile for both case studies. The consultative workshops were held to orientate the research around the central problems and challenges related to curriculum alignment with provincial Climate-Smart Agricultural policies. The methodology thereafter was developed as an iterative process of successive intervention-innovation workshops where the participating staff in each college reviewed their curriculum with the support of a Climate-Smart Innovation Tool. This tool was developed as a mediating resource for participants to undertake intervention work towards curriculum innovation in their context. The historical analysis from the two consultative workshops and the data derived from the initial use of the Climate-Smart Innovation Tool was used to model the activity systems in the respective colleges and the provincial system. This analysis enabled the researcher to scope how the system was currently functioning and how it had changed over time. During the workshops, curriculum innovations were reviewed and a fuller picture of the challenges of system innovation emerged, especially from a curriculum innovation vantage point. This system analysis was used to analyse emergent tensions and contradictions within the system and to build a picture of the complexities of participating staff initiating innovations towards Climate-Smart responsiveness in the colleges and within the Agricultural Innovation System. During the review and tracking of the supported innovation process the Climate-Smart Innovation Tool was developed into online sub-tools where either Departments or individual lecturers could review and track their own Climate-Smart responsiveness. The tool was shown to be a useful tool for surfacing contradictions, and identifying absences, and thus for charting out the start of reflexive learning and change processes needed for introducing climate responsive knowledge into the system. The study reveals that catalysing of curriculum and learning system innovation aligned with wider innovations in the agricultural innovation system requires specific tools, time and the understanding of the importance of micro-level innovation. The innovations within the system revealed the significance of allowing for time and processes that facilitate ‘ascending’ from the abstract concept of Climate-Smart Agriculture into more concrete curriculum processes. The curriculum review tool developed for this study served as an important double stimulation tool, along with activity system mapping, and ongoing refinement and clarification of the object of Climate-Smart Agriculture and associated contradictions and action plans for climate smart responsiveness in the college context. The tools and processes that were developed during this study, assisting in the emergence of micro-level innovation of the curriculum and learning system. The barriers and processes hampering curriculum and learning innovation within the system were identified. The study concludes with the recommendations on how a Climate-Smart innovation process might best be supported with reflexive tools within a curriculum and learning system during a time of institutional flux.

Social media websites are reported to be the most popular around the world. In the government sphere, social media is purported as a technology that will revolutionise citizen participation, service delivery and government-citizen interactions. Accordingly, governments around the world are steadily implementing social media in a bid to meet citizens’ demand for immediate and constant access to information, as well as increased opportunities to participate in government. Public participation has become an important focus area for government which could be used to effectively engage citizens and foster citizen trust. The United Nation’s E-government survey reports the presence of 125 countries on social media platforms. Despite the increased use of social media by governments, consensus among researchers is that governments need guidance on how to use social media effectively to achieve the potential benefits proposed by these technologies. Many social media adoptions by governments have been deemed as experimental; no formal action plan was designed, and many government employees are expected to learn social media use on-the-job. The aim of this research was to investigate and propose a social media model for public participation to leverage the opportunities provided by social media and present an effective and structured approach towards public participation. The research was designed as a mixed methods research using a case study based in the Eastern Cape Province of South Africa. The research involved a survey of citizens in the selected municipality based on the Uses and Gratifications Theory, interviews with employees responsible for social media in said municipality and a contents analysis of the existing social media pages of the municipality. The model was developed from the findings of the survey, interviews and existing literature. The implementation of the model was done in the Nelson Mandela Bay Municipality. The municipality appointed a social media champion responsible for obtaining support from top management and politicians within the municipality. Additional staff were added to the social media team and formal social media training was provided to the team. An official social media strategy was drafted and at the time of writing, needed to be approved by top management. The proposed model was operationalised within the Nelson Mandela Bay Municipality. This research makes several contributions to the E-government and social media fields in South Africa. The major contribution is the provision of guidance for South African municipalities to implement and use social media in an effective manner to achieve public participation. The research provided a phased approach to social media implementation that eliminates ad hoc experimentation and ensures the municipality’s social media activities are effective. The development of the model was based on the characteristics of the municipality and its citizens derived from the interviews and survey carried out. There are five phases in the model; Initialisation, Setup, Organisation, Institutionalisation and Maintenance. The model can be thought of as a guideline, and as such municipalities should adapt the implementation of the model to fit their organisational characteristics. The social media model will assist municipalities to determine the resources, tools and tactics to enable them to implement social media effectively, which will result in an improved engagement and participation process with citizens, and thereby foster trust.

- Description: The possible role and involvement of the Church in social development has reemerged as an important focus of contemporary academic and religious development discourse in South Africa. There are strong voices arguing for churches and other Faith-Based Organisations to be regarded as strategic in contributing to addressing the challenge of poverty as agents of social development. Yet, as church congregations multiply throughout South Africa, they appear to be less responsive to the challenge of poverty facing South African communities, contrary to the rich history of churches in the past. The need for churches to be involved in sustainable community-driven development initiatives to fight poverty in their local communities cannot be denied nor be met with just rhetoric and scholarly dissertations by theologians and academics. The vicious cycle of poverty in our communities must be eradicated as it represents a social injustice in terms of South Africa‘s Constitution and speaks to deep structural inequalities inherent in our society. Whilst researchers have made several proposals for churches to move from social welfare and relief, there appears to be little research with a clear practical strategy which congregations can implement to enhance their social service delivery role from social relief to sustainable community development. This has left a considerable gap which the current research sought to address. This study thus responds to the call by previous research for churches to implement strategies other than mere relief. Hence, this study contributes to the religious development discourse in South Africa, by developing a strategy to enhance Church-based social service delivery initiatives from social relief efforts which are not sustainable, to community development efforts which are sustainable and which will be consistent with the current social development policy context and contextually relevant to the socio-economic challenges of poverty and its consequences in South Africa. The study was conducted in two phases. During phase one, the main purpose was to gain a deeper understanding of the historical and current involvement of the Church in providing social services which address poverty in communities, to enhance understanding of the factors which influence the provision of social services by churches, as well as to understand participants views of how church-based social service delivery can be improved in order to fight poverty. For phase two, the goal was to develop a strategy to enhance church-based social service delivery from being social relief to being community development oriented. The following objectives guided the research process: To review selected and applicable literature to gain a deeper understanding of the historical and current involvement of the Church in the delivery of social services in order to fight poverty; To explore and describe the perceptions of church leaders and congregation members of the historical and current involvement of the Church in the delivery of social services in order to fight poverty; To explore and describe the factors which influence Church-based social service delivery in fighting poverty; To explore the views of church leaders and congregation members on how church-based social service delivery can be improved in their churches to inform the development of a strategy to enhance church-based social service delivery in fighting poverty. This study employed a qualitative research approach grounded in the interpretivist social science paradigm. The qualitative research approach necessitated an exploratory, descriptive and contextual method of inquiry. A descriptive case study method was also used, with the Methodist Church of Southern Africa selected as the main case of focus. The target population in this research comprised of Christian churches with a historical involvement in social service delivery in pre-apartheid South Africa. Purposeful sampling of 5 churches was undertaken, namely; Roman Catholic Church (RCC), Anglican Church (AC), Dutch Reformed Church (DRC), KwaSizabantu Mission (KSB) and Methodist Church of Southern Africa (MCSA). Data collection was conducted in two phases. Phase one comprised a literature review; Phase two comprised gathering empirical evidence by conducting face to face semi-structured interviews with clergy and from conducting one focus group interview with congregants. The information obtained from participants was transcribed, coded and analysed using content analysis and by a computer-assisted qualitative data analysis software (CAQDAS), namely ATLAS.ti. Findings revealed a marked difference between the historical and current churchbased social service delivery suggestive of decline, accompanied by the lack of empowerment opportunities for current church leaders and congregation members in community development facilitation. Further evidence suggest the lack of cooperation between church leaders and congregation members; as well as the lack of sustainability of interventions owing to an absence of resources and the lack of capacity to create sustainable economic opportunities. Findings also revealed that church congregations are rich with people with various assets - skills, strengths, capabilities, passions, gifts, talents in various fields, which they can share with one another as congregations and communities. The discussion of findings reflected that historically, Church-based social service provision involved holistic intervention mechanisms, empowerment, collaborations and sustainability of interventions suggestive of second generation strategies of community development, while currently, Church-based social service provision involves mostly social relief and social welfare efforts suggestive of first generation strategies. The findings suggest a holistic strategy for ―reawakening the co-operativeness‖ of congregations to facilitate sustainable Church-based social service delivery towards fighting poverty in local communities. The strategy which was then developed and described with its sub-strategies, namely: Establishment of collaborative relationships Creation of empowerment opportunities Facilitation of holistic interventions The goal of the strategy is to guide church leaders and congregation members in facilitating sustainable Church-based social service programmes to fight poverty.

- Description: Reading is an integral part of education from which one gets access to information. Unfortunately, reading ability among primary school pupils, the foundation level of education, is at its lowest ebb. These pupils when they get to secondary schools eventually fail external examinations-a situation which according to National Examination Council, is caused by inappropriate teaching methods. Consequent upon this, this study assessed active learning strategies used by teacher during English reading comprehension lessons in six selected primary schools in Nigeria. The main research question was: How do teachers employ active learning strategies in teaching English reading comprehension? The study adopted qualitative approach and case study design. With the use of purposive sampling technique to select six head teachers, six primary VI teachers, two members of the School Basic Committee, the Director Local Government Education Authority and six focus groups. The study used interviews, documents and focus group interview as research instruments to collect data. Data were analysed based on interpretivism paradigm which interpreted participants’ views according to the word view of the participants. The study found out that teachers have good knowledge of active learning strategies and use them in teaching English reading comprehension lessons but are faced with some daunting challenges such as non-availability of instructional materials, lack of library, lack of qualified teachers and lack of time. The study concluded that students fail woefully in English reading comprehension because teachers do not use appropriate teaching techniques. The study recommend that teachers must use active learning strategies effectively and more often during English reading comprehension, more time should be allocated for English reading comprehension, effective use of instructional materials should be considered and the government should employ specialist teachers to teach English reading comprehension.

- Description: There is an ever present need from Internet users for more bandwidth. This is manifested by continuous increase in bandwidth demanding applications such as 5G wireless, new end user consumer links like thunderbolt, video conferencing, high definition video-on-demand transmitted over the Internet and massive data transfers required with and within data centres for backup, storage and data processing in cloud computing. Fibre optic communications technologies are playing a pivotal role in communication, being a major enabling technology in our increasingly Internet-centric society. As network services continue to become more dynamic and diverse, Internet service providers are faced with a challenge of cost reduction in the transmission network, power and spectral efficiency as well as scalability of the optical network infrastructure to support incremental expansions and virtual machines. Intelligent design of terrestrial optical networks to allow for simultaneous signal transmission through shared network infrastructure, and the use of low cost, power efficient, high bandwidth transmitters such as vertical surface emitting lasers (VCSELs) as well as exploitation of spectral efficient in-complex advanced modulation formats is a viable approach to this situation. In this study, techniques for spectral efficiency upgrade and simultaneous transmission of data signal, reference frequency (RF) clock signal and pulse-per-second (PPS) over shared infrastructure have experimentally been optimized in a laboratory environment for adoption in next-generation telescope array networks such as the Square Kilometre Array (SKA), time keeping systems such as banking systems, Coordinated Universal Time(UTC) timing and Global Positioning Systems (GPS), as well as high capacity spectral efficient short reach optical fibre networks such as data centres. This work starts by experimentally optimizing VCSEL technology for simultaneous transmission of 10 Gbps data and 1.712 GHz RF clock signal over a single G. 655 optical fibre of length 24.75 Km at different channel spacing and different propagation direction for implementation in a cost effective next-generation telescope array network. The wavelength tuneability property of VCSEL transmitters allows for wavelength adjustment, a key requirement for simultaneous data and RF clock signal transmission over a single optical fibre. A receiver sensitivity of -19.19 dBm was experimentally achieved at back-to-back analysis. A 24.75 Km of simultaneous data and RF clock signal transmission performed at 0.4 nm channel spacing introduced a transmission penalty of 1.07 dB and 1.63 dB for counter and co-propagation scheme respectively. This work mainly utilized direct modulation and direct detection using a positive intrinsic negative (PIN) due to its simplicity and cost effectiveness. A novel modulation technique for simultaneous data and polarization-based pulse-per-second timing clock signal transmission using a single VCSEL carrier is experimentally demonstrated. Two signal types, a directly modulated 10 Gbps data signal and a polarization-based pulse per second (PPS) clock signal are modulated onto a single mode 10 GHz bandwidth VCSEL carrier at 1310 nm. Spectral efficiency is maximized by exploiting the inherent orthogonal polarization switching of the xiv VCSEL with changing bias in transmission of the PPS signal. A 10 Gbps VCSEL transmission with PPS over 11 Km of G.652 fibre introduced a transmission penalty of 0.52 dB. The contribution of PPS clock signal to this penalty was found to be 0.08 dB. A technique for simultaneous directly modulated data and phase modulated reference clock signal transmission over a signal channel in wavelength division multiplexing (WDM) solutions is experimentally demonstrated. This is to prepare solutions to the ever-increasing demand over gigabit/s, terabit/s and gigahertz capacities in WDM-based terrestrial optical fibre transmission systems such as telescope array networks. a total capacity of 30 Gbps (310 Gbps) data and 12 GHz ( 4 3 GHz) reference clock signal are multiplexed at a channel spacing of 100 GHz and simultaneously transmitted over a single mode G.655 fibre of length 24.73 Km. The recovery of the phase modulated RF clock signal using a differential delay line interferometry technique is experimentally demonstrated. A 625 Gbps (2525 Gbps) DWDM data transmission system is further implemented in simulation by multiplexing 25 channels at 25 Gbps per channel using 50 GHz channel spacing. A four level pulse amplitude modulation (4-PAM) data modulation format employing VCSELs is experimentally demonstrated for adoption in high bitrate networks such as big data science projects and data centre networks. 4-PAM offers a good trade-off between complexity, efficiency, reach, and sensitivity. A software defined digital signal processing (DSP) receiver is designed and implemented in MATLAB to recover the transmitted 4-PAM data signal cost effectively without the necessity of costly receiver hardware. A novel technique for maximizing carrier spectral efficiency through simultaneous 20 Gbps 4-PAM data and phase modulated 2 GHz RF clock signal transmission on a single mode 10 GHz bandwidth VCSEL carrier at 1310 nm is experimentally demonstrated for the first time to the best of our knowledge. Data transmission and clock stability performance of the designed high spectral efficient VCSEL-based link network is evaluated through BER curve plots, phase noise measurements and Allan variance analysis respectively. VCSEL-based Raman amplification is experimentally demonstrated as a viable approach for RF clock signal distribution in extended reach astronomical telescope array networks and other extended reach terrestrial optical fibre network application. This is achieved by adopting two pumping techniques namely forward pumping and backward pumping. A maximum on off gain of 5.7 dB and 1.5 dB was experimentally attained for forward pumping and backward pumping at 24 dBm pump power respectively, while a maximum 100.8 Km fibre transmission achieved experimentally. In summary, this study has successfully demonstrated in-complex, spectral efficient, low cost and power efficient simultaneous data signal, reference frequency (RF) clock signal and pulse-per-second (PPS) transmission techniques over shared network infrastructure. Simultaneous transmission of data, RF clock and PPS timing signal is relevant in nextgeneration telescope array networks such as the Square Kilometre Array (SKA), time keeping systems such as banking systems, Coordinated Universal Time (UTC) timing and Global Positioning Systems (GPS), as well as high capacity spectral efficient short reach optical fibre networks such as data centres.

- Description: This work shows how legacy and novel radio Interferometry software packages and algorithms can be combined to produce high-quality reductions from modern telescopes, as well as end-to-end simulations for upcoming instruments such as the Square Kilometre Array (SKA) and its pathfinders. We first use a MeqTrees based simulations framework to quantify how artefacts due to direction-dependent effects accumulate with time, and the consequences of this accumulation when observing the same field multiple times in order to reach the survey depth. Our simulations suggest that a survey like LADUMA (Looking at the Distant Universe with MeerKAT Array), which aims to achieve its survey depth of 16 µJy/beam in a 72 kHz at 1.42 GHz by observing the same field for 1000 hours, will be able to reach its target depth in the presence of these artefacts. We also present stimela, a system agnostic scripting framework for simulating, processing and imaging radio interferometric data. This framework is then used to write an end-to-end simulation pipeline in order to quantify the resolution and sensitivity of the SKA1-MID telescope (the first phase of the SKA mid-frequency telescope) as a function of frequency, as well as the scale-dependent sensitivity of the telescope. Finally, a stimela-based reduction pipeline is used to process data of the field around the source 3C147, taken by the Karl G. Jansky Very Large Array (VLA). The reconstructed image from this reduction has a typical 1a noise level of 2.87 µJy/beam, and consequently a dynamic range of 8x106:1, given the 22.58 Jy/beam flux Density of the source 3C147.

- Description: This work shows how legacy and novel radio Interferometry software packages and algorithms can be combined to produce high-quality reductions from modern telescopes, as well as end-to-end simulations for upcoming instruments such as the Square Kilometre Array (SKA) and its pathfinders. We first use a MeqTrees based simulations framework to quantify how artefacts due to direction-dependent effects accumulate with time, and the consequences of this accumulation when observing the same field multiple times in order to reach the survey depth. Our simulations suggest that a survey like LADUMA (Looking at the Distant Universe with MeerKAT Array), which aims to achieve its survey depth of 16 µJy/beam in a 72 kHz at 1.42 GHz by observing the same field for 1000 hours, will be able to reach its target depth in the presence of these artefacts.

- Description: It has become standard practice at Higher Education Institutions (HEIs) for their Internet management and relevant Information and Communication Technology (ICT) resources, specifically Internet resources, to be continuously investigated by HEI Management as well as by their users. The reason is that the Internet has become the foundation on which most ICT and business resources function and therefore is labelled as a distinctive competency for the HEI. HEIs, however, have limited ICT Internet resources and are expected to use these resources optimally, to ensure efficient and effective Internet connectivity on all campuses and to all users and systems. The management of Internet resources at South African Higher Education Institutions (SA HEIs) are the focus of this thesis. The primary purpose therefore, is to provide a proposed adaptive Internet Management Model for HEIs which will assist them to achieve prime value from their Internet management resources. This was realised by firstly; identifying the current Internet Management Business Models of the SA HEI landscape; secondly, determining what the Internet users of the Nelson Mandela University, a South African Higher Education Institute situated in the Eastern and Western Cape area in South Africa, were using the Internet for; thirdly, comparing these findings to the actual Nelson Mandela University Firewall data and lastly, using the combined findings to draw conclusions and create a proposed adaptive Internet Management Model for HEIs. This can assist the HEI ICT Management team to realign the Internet resources to match the current business and customer requirements. This thesis is an exploratory, mixed method study which consists of literature studies, surveys and cross sectional studies. The literature studies were conducted on secondary sources to identify the national and international governance structures that influence Internet management. The empirical study which consisted of two surveys was compiled from existing surveys as well as from literature studies and was completed by its respective respondent groups. The first survey was used to gain insight into what was considered the standard Internet Management Business Model at HEIs in South Africa. The second survey was used to gain insight how the Internet was being used at Nelson Mandela University by staff and students. Lastly, an extract of the Nelson Mandela University Firewall data were gathered and used to confirm or deny results from the previous survey. The findings of the first survey, HEI Internet Management Survey (HEIIMS), confirmed that the Internet and its relevant resources are extremely important to all HEIs. The HEIs Internet Management Business Models are to a large extent aligned with the National Research an Education Networks (NRENs) business models with some adjustments. The HEIs indicated that they cater for a large Internet community but do not differentiate between them. The findings do, however, specify that some differentiation does take place. The HEI Internet is provided to the Internet community at no cost and is funded by Council funds. The requirements of staff and students are mostly similar with some priority differences to key content needs. The Internet resources of the HEIs are very much aligned to support the physical infrastructure of the Internet. HEIs consider the NRENs to be key partners and suppliers with additional local suppliers used as secondary support. The second survey, Nelson Mandela University Internet Usage Survey (NMUIUS), indicated that there was a wide gap between how the Internet was used by the staff and students. The findings indicated that staff tend to be more aware of the policies and surrounding practices while students appeared somewhat unaware. The staff and students have different needs for the Internet and these needs also change slightly according to the time of day and day of the week. Regarding content access (including Firewall data), some of the users said Internet practices were true whilst others were false. The majority of those giving a false opinion said that said Internet practices were focused on activities linked to cyberloafing content. In addition, they stated that these activities were undersold, meaning that they said that they access the Internet content rarely while the Firewall data indicated that it was frequently being accessed and by many users. It was clear that the staff received a pleasant Nelson Mandela University Internet experience while the students received a slightly degraded Internet experience. The study concluded with the development of a proposed adaptive Internet Management Model for HEIs and recommendations and considerations on how to improve the current Nelson Mandela University Internet management strategy. This thesis makes a contribution towards the body of knowledge by identifying and discussing current national and international Internet Governance (IG) practices. It continues by identifying the current SA NRENs and their business models which overflow into the HEI landscape. This is followed by an investigation into the various HEI Internet Management Business Models, current usage of the Nelson Mandela University Internet and patterns of use and Nelson Mandela University Firewall data. The thesis will therefore assist readers to understand the effective and efficient management of their Internet usage requirements and the provision of Internet resources. This in turn, will confirm that the availability of the Internet for its users and systems becomes a productive, reliable and pleasant experience.

- Description: The South African government has attempted to address various transformation and efficiency challenges in the system through the steering mechanisms at its disposal. This study analyses the implementation of one of these mechanisms, the Teaching Development Grant (TDG), which is designed to enhance student learning through the improvement of teaching and teaching resources at South African universities. Since the inception as an earmarked grant ten years ago, a total of R5.5 billion has been allocated for the TDG. The study thus sought to answer the question: What are the factors enabling and constraining the use of the TDG to enhance teaching and student success at South African universities? A total of 275 TDG progress reports and budget plans were analysed alongside other TDG documentation such as TDG payment letters to universities and institutional submissions that universities made on the use of the TDG for the 2008 TDG Review. The TDG criteria and policy over the years were also included as data. The analysis used Archer’s (1995; 1996) morphogenesis/stasis framework, which is concerned with how change does or does not happen over time. Archer’s analytical dualism was used to identify the interplay of structural, cultural and agential mechanisms shaping the emergence of and practices associated with TDGs in order to make sense of the events and experiences in the data. One of the main findings of the study was that the historically-based differentiated nature of the South African higher education landscape constrained the implementation of the TDG. The stark resource differences in the sector has meant that the TDG has not fully translated into system-wide gains. In the initial years of TDG implementation from 2004 to 2013, most institutions did not use the TDG for teaching development initiatives per se, but rather spent the bulk of the funds on infrastructure and equipment. Such resource gaps have persisted and continue to compromise the academic enterprise at affected universities. The data also showed that universities which have access to additional funding other than state funding have been able to augment and advance their own funds and were thus able to at least partially counter late payments of the TDG, fluctuations in allocations, and the short-term nature of TDG budgets and inadequate allocations. This enabled relatively straightforward implementation of the teaching and learning enhancement programmes at these universities, while there were ongoing implementation difficulties at the universities with the lowest success rates, the very institutions the grant was most targeted to address. The study showed that the shortage of appropriate teaching and learning staff constrained the nature and type of interventions. Historically Disadvantaged Institutions in particular struggled to attract and retain the much-needed expertise. This emerged from multiple structural constraints such as geographical location, conditions of work, inefficient human resources systems, lack of access to financial resources for competitive packages, and instability in governance and management structures at some universities. Emerging from the data in the study is the fact that staffing challenges remain one of the core constraints in the implementation of the TDG. In particular, the data indicated that teaching and learning staff hired on the basis of TDG funds were generally hired as part-time or contract staff. This meant that their academic qualifications and experience in teaching development were limited and, in many cases, it meant that the posts were not filled at all. In some cases, the fluctuating budgets meant that some projects had to be downscaled or abandoned altogether. The study found that many of the interventions that were implemented had tenuous links to teaching and learning and, even where there were such links, these interventions were often based on fairly a-theoretical, common-sense understandings of what would develop teaching. In many universities, there was little evidence of institution-level planning of interventions aimed at fundamentally addressing the need for teaching development. The limited access to teaching and learning expertise across the sector was mirrored in the uneven distribution of expertise in administration, financial management, institutional planning and human resource divisions, which had implications for the establishment of monitoring systems and implementation processes of the TDG. The lack of strong systems and policies encouraged cultures that did not value transparency, accountability or compliance to the TDG policy. The role of corporate agency in the form of leadership and ownership of projects emerged as a key enabler in the implementation of the TDG. All of these structures shaped the ability of institutions to spend the TDG and in some cases millions of Rands in funds were not spent and so were withheld. The study found that the inability of some universities to spend was exacerbated by the problem of a lack of alignment between the DHET financial year and the academic year. Although the TDG has made a notable contribution to the advancement of teaching and learning (T&L) nationally, this study revealed that the blunt implementation of the TDG across the sector constrained the gains. In particular, the practice of withholding unspent funds focused only on the symptoms of underspending and not on the structural, cultural and agential mechanisms that led to such under-expenditure. The withheld funds were redirected by the government for national projects but as all universities including the well-resourced Historically Advantaged Institutions (HAIs) had access to these withheld funds this translated into a regressive distribution of the TDG. Limited capacity within DHET to direct, manage and monitor the grants has also had a constraining effect on their use and the secondment of a teaching and learning expert to the department was seen to be a significant but short-term enablement in this regard. The findings of how the TDG implementation has emerged in the South African higher education sector are particularly important at this point in time as the TDG together with the Research Development Grant will be reconfigured into a new grant called the University Capacity Development Grant as from 2018. This study provides significant insights into the structural, cultural, and agential enablements and constraints of this new grant being able to drive changes in the sector. The findings also provide insights into the implementation of other earmarked grants. , Boma la South Africa layesera kuthetsa mavuto omwe amadza posintha ndi kulongosola zinthu kudzera mu njira zosiyanasiyana.

- Description: This thesis examines the role of cash and in-kind transfers in alleviating urban household food insecurity in Makokoba and Njube townships in Bulawayo, Zimbabwe. This assessment focuses on understanding the extent to which these transfers improve poor household access to food. The implications of cash and in-kind transfers on household dietary diversification are also examined. The thesis also scrutinises factors that deter the effectiveness of these transfers in addressing urban household food insecurity in the two townships. The study is guided by the Entitlement Approach (Sen, 1981) and Household Livelihood Security Framework (Frankenberger et al., 1995). The study combined qualitative and quantitative research methods in gathering and analysing data. Semi structured in-depth interviews, questionnaires, and key informant interviews were used to collect primary data. The thesis finds that cash and in-kind transfers have not significantly alleviated urban household food insecurity in Makokoba and Njube townships. As a result households receiving these transfers have not meaningfully improved their food consumption behaviours. Households continued to experience food insecurity characterised by skipping meals and eating small portions. Most households prioritised non-food expenditures and this has resulted in expending a small proportion of their cash transfers on purchasing inadequate food items. Both transfers have not meaningfully played a complementary role in enabling poor households to access a variety of food groups necessary for diversifying diets. The thesis also finds that a legion of factors deter the effectiveness of cash transfers in these townships. These include irregular distributions, low cash transfer value, incomplete food baskets, weak targeting mechanisms, less flexible implementation processes, automatic deletion of households from beneficiary database and duration of programmes. This thesis recommends redesigning of these cash and in-kind transfer programmes to effectively alleviate urban household food insecurity.

- Description: Tanzanians continue to demand improved performances and better-quality services from public organizations and the government at large. Since independence in 1961, the Tanzanian government continued to undertake a restructuring of different policies, laws and regulations in public services to improve performances and service delivery. Among the results of the restructuring was introduction of Performance Management System(PMS) across public organizations. The system meant to address and redress not only the concerns of the public on improved performances and better services, but also inculcate performance-oriented culture and accountability for results. Despite such efforts by the government, some of the problems existed before the introduction of PMS such as among others weak incentives and accountabilities, and management skills continue to impede issues of improved performance and service delivery in public organizations. It is from this context that the researcher was encouraged to research on issues of performance management system, highlighting specific areas of its effectiveness to improve performance, motivational factors, use of performance appraisal results on different decisions-making and factors for underperformances which affect organizational performances in public organizations. This study employed a mixed method research design involving both quantitative and qualitative strategies. For the qualitative strategy, data were gathered using in-depth interviews and document reviews; and for the quantitative strategy, questionnaires were used in which the relationship of different variables for the study were statistically analyzed using the SPSS Version 22. In the overall, the study evidences show a strong pressure of support at government level in terms of formulating policies, laws and regulations to back up performance management system to improve performance quality service delivery, but there is less support in public organizations levels. It became clear that many problems still make PMS effectiveness not pragmatic: Political interferences to management of public organizations, government bureaucratic procedures in amendments of outdated laws, inflexible scheme of services important for rewards and incentives and the use of manual voting system for good performances are among problems that the study identified. Furthermore, evidences have shown that a top-down management approach bottlenecks the overall implementation of performance enhancing tools for performance management system effectiveness. There is lack of workers’ participation and ownership of tools such as, strategic plans, client service charters and open performance reviews and appraisal system and the general system, and thus becoming hard to implement it in the public organizations. The study suggests practical initiatives by the government to establish highly strict quality service delivery satisfaction tracking system to allow both employees and citizens to evaluate internal and external performances of the public organizations. The findings upheld vulnerability of PMS to improve performance and service delivery, and therefore more attention and adherence to principles of performance management and laws that are biting to issues of underperformances are imperative.

- Description: The implementation of Small, Medium and Micro Enterprise (SMME) strategy are not well understood and have rarely been addressed all nationally. The objectives of this study are, therefore, to establish a base level of understanding in order to assess the implementation of SMME strategy used by the Amathole District Municipality (ADM) Local Economic Development (LED) managers in disseminating information; analyse the structure for implementing SMME strategy used by the ADM LED managers; examine the challenges confronting the ADM LED managers in implementing SMME strategy; examine the skills needed by the ADM LED managers to adequately formulate and implement SMME strategy; and make recommendations to the municipality on how best the implementation of SMME strategy can support growth and development in the ADM. The study used a qualitative research design that involves a systematic review of documents. Data was collected through the review and analysis of available existing documents. Data analysis included using the documentary analysis derived from the journals, and books as well as reviewing the various data analysis done in relation to an assessment of the implementation of SMME strategy: A Case of Amathole District Municipality. Findings from previous literature revealed that there are constraints faced by the Amathole District Municipality (ADM) Local Economic Development (LED) Managers in implementing SMME strategy. The study confirmed some of the operational challenges were due to incompetency among the municipal managers, and lack of clear understanding of the implementation of SMME strategy used to support grow and development of SMME in the Amathole District. This study provides effective solutions to the identified challenges and impact as well as strategies to be adopted in order to alleviate poverty and provide job opportunities to the local communities. The implications of the findings are that unless the barriers named above are resolved, poverty and unemployment will continues escalating, communities will continue receiving and experiencing poor service delivery in the ADM and thus, would undoubtedly lead to poor economic growth and development. Management of the municipality must ensure that qualified ADM Managers are permanently employed and allowed to partake in the implementation of SMME strategy and community participation should be well encouraged as well as embarking on effective implementation of SMME strategy that would create an enabling and conducive environment for the small firm enterprises.

- Description: The study sought to assess the role of Life Orientation teachers in promoting Career Guidance and Counselling for learners in secondary schools, and to establish strategies that can be implemented to improve their practice. The study followed a qualitative approach with case-study research design. The population consisted of Life Orientation teachers and learners from secondary schools. Purposive sampling was used to select 18 Life Orientation teachers who are teaching the subject in six secondary schools. A total number of 12 learners from Grade 10- 12 were selected to participate in the study. The study employed three data collection instruments; namely, one-on-one interviews, focus group discussions and questaviews. Data were categorised into themes, analysed and discussed accordingly. A number of findings emanated from the study. Life Orientation teachers understand their role but despite their understanding of such roles, they lack the necessary skills to fully equip learners with relevant knowledge so that they are able to choose careers that match with their subjects of specialization. The study revealed that Life Orientation teachers experience challenges, lack of training, lack of support by different stakeholders, the negative attitude towards the subject by both learners and Life Orientation teachers, the shortage of Life Orientation teachers, the subject is not valued like other subjects, poor parental involvement by parents and constant rotation of Life Orientation teachers. As a result, learners were not fully equipped in terms of knowledge and skills to choose the right subjects for specific careers and instead, some relied on their intuition while others relied on their peers. The study recommended that the Department of the Basic Education should appoint competent staff to address the unique academic/educational, psycho-social and career/vocational problems faced by learners in school, and for them to train the Life Orientation teachers as well. The subject should be taught by permanently by qualified teachers without being shifted to other subjects and to ensure that such teachers gain experience in the subject. This would add status and value to the subject.

- Description: This study undertook an extensive evaluation of state assisted Human Settlement development, with specific vigor on the case study of Reeston Human Settlement project in Buffalo City Metropolitan Municipality in the Eastern Cape. This was motivated by a number of factors such as satisfaction issues in the area of Human settlements and the issues that continue to hinder the effective delivery of houses such as availability of land, the willingness of the beneficial to relocate to the allocated houses. South Africa is in its 24 years of democratic dispensation, the human settlements continue to be the thorn in a flesh in the government effectiveness. The existing legislation on the housing development serves as the cornerstone of development, housing theories also continue to be the guiding principles under which the development can flourish if followed to the latter. It is evident that, the democratic government in the country has delivered millions of houses to the beneficiaries, thus restoring dignity to many. However, there has been significant backlog of over 2.1 million houses. This is based on the housing waiting list available with the various Local Municipalities and the respective provinces department is Human Settlements. The objectives of the study was taken into consideration in ensuring congruence with the study aim. The objectives are stated below is to evaluate the application of Human settlement programmes, policy imperatives, implementation and practice in South Africa by means of the case study of the Reeston project in the Eastern Cape. The following objectives are set for the study: To analyse the policy and institutional framework guiding the establishment of state-assisted human settlement projects in the country. To analyse the level of execution in the selected human settlement projects in the Buffalo City Metropolitan area reflected the policy and institutional framework for the establishment of state-assisted human settlements. v To ascertain the beneficiaries’ narratives about the projects (and the overarching policy/institutional framework), and what socio-cultural and/or economic factors, if any, mediate those narratives. To detail the socio-economic conditions and livelihood strategies of Reeston Human settlements residents. The study took the combined method of research, being the qualitative and quantitative research method. The choice of a research approach is guided among others by three main aspects: the research problem, the researcher’s experience and the audience at whom the research is directed. A mixed approach method has been employed for this study, because as several authors confirm, this is how to get the best out of both the qualitative and quantitative approaches. The evaluation took the analysis of the Duncan Village, looking at the transition from the informal settlements to the Reeston Housing development in the Eastern Cape Province. Respondents were visited in their places of comfort where they were able to express themselves so that the researcher can be able to retrieve more information in this regard. The findings of the research revealed the level of satisfaction, dwelling attributes, neighborhood issues, environmental issues for consideration in the housing development as a form of dwelling. The study contributes significantly to the body of knowledge as it provides solution to the provision of housing development in South Africa, especially the Duncan Village as a prime site for development for Buffalo City Metropolitan Municipality. The study presents a new model for developing houses in the informal settlements without relocating the beneficiaries from their area of comfort. A sustainable housing development to the need of the people will be the one that is re4sponsive to the findings of this study, these are: satisfaction with the government services rendered in the area, the surroundings in the dwellings and most importantly the environmental considerations

The evaluation took the analysis of the Duncan Village, looking at the transition from the informal settlements to the Reeston Housing development in the Eastern Cape Province. Respondents were visited in their places of comfort where they were able to express themselves so that the researcher can be able to retrieve more information in this regard. The findings of the research revealed the level of satisfaction, dwelling attributes, neighborhood issues, environmental issues for consideration in the housing development as a form of dwelling. The study contributes significantly to the body of knowledge as it provides solution to the provision of housing development in South Africa, especially the Duncan Village as a prime site for development for Buffalo City Metropolitan Municipality. The study presents a new model for developing houses in the informal settlements without relocating the beneficiaries from their area of comfort. A sustainable housing development to the need of the people will be the one that is re4sponsive to the findings of this study, these are: satisfaction with the government services rendered in the area, the surroundings in the dwellings and most importantly the environmental considerations

- Description: Low risk and high risk pregnant women (HRPW) with gestational diabetes mellitus (GDM) who practise sedentary life style are at risk of overweight and obesity that predispose to gestational diabetes mellitus (GDM). The purpose of the study is to describe the effectiveness of an intervention strategy of modified diet and planned physical activity implemented amongst low-risk and high-risk pregnant women with GDM in Buffalo City Metropolitan Municipality in the Eastern Cape, South Africa. Quantitative experimental intervention design and stratified random sampling was used for drawing a sample of low-risk and high risk pregnant women with GDM. A sample size 291 of LRPW and n=34 HRPW were eligible for the study. The sample frame of the study was taken from the registers of the CHCs, Frere Hospital and Cecilia Makiwane Hospital (CMH). Questionnaires were used to collect data from the low and high risk pregnant with GDM. Descriptive statistics (frequency, percentages, mean and standard deviation) were used for categorical variables. A p-value of < 0.05 was considered statistically significant. The total analysed of LRPW were n=135 and HRPW n=34 all in control group due to miscarriages, phone loss and relocation. LRPW had some risk factors of overweight (6.2 percent), obesity (15.5 percent), family history of diabetes (16.5 percent). HRPW also had overweight and obesity of (14.7 percent) and family history of (26.4 percent) as the Pvalue was statistically significant of weight was 001, MUAC Pvalue of 000 and Pvalue of BMI 000. There were alarming abnormalities of urinalysis of protein, glucose, leucocytes and blood in urine. The LRPW and HRPW had consumption of high content of carbohydrates, vegetables, fats and low in fruit, vegetables and fibre diet. Both LRPW and HRPW were also interested on the education about modified diet benefits (95.1 percent) and modified diet programs networks (87.5 percent). The barriers showed that LRPW and HRPW were low motivation (90 percent) minimal knowledge and benefits of modified diet (93 percent) and socio-cultural issues (86 percent). The majority of participants both LRPW and HRPW showed the interest in the planned physical activity benefits especially frequent education (96.9 percent) and encouragement of social support networks (90.2 percent) and convenient location (89.4 percent). But the HRPW had lower engagement than the LRPW in planned physical activity and is associated with risk of GDM. Although pregnant women were faced with fatigue and low energy (98.6 percent), as pregnancy progresses, minimum information regarding benefits of planned physical activity (87.6 percent) and the socio-cultural influence (77.8 percent). The recommendations are education on frequent use of modified diet and planned physical activity that is available, less economical and within their context. Frequent screening of all pregnant women during pregnancy of BMI, MUAC and weight and educate accordingly. The availability of dietician and physical activity speciality is needed.

- Description: Several pyrroloiminoquinone alkaloids exhibiting cytotoxic, anti-tumour activity have been isolated from sponges within the Latrunculiidae family that are endemic to the South African coastline. Other, structurally similar pyrroloiminoquinone compounds have been isolated from geographically distant and phylogenetically distinct marine sponges, as well as terrestrial myxomycetes which suggested that sponge-associated bacteria may be the true biosynthetic origin of pyrroloiminoquinone compounds. Previous studies have shown that there is conservation of spirochete and betaproteobacterial species in the bacterial communities associated with South African Latrunculiidae sponges and it was proposed that these conserved bacteria represented candidate pyrroloiminoquinone-producers. This study aimed to confirm the conserved dominance of betaproteobacteria and spirochetes within bacterial communities associated with South African latrunculid sponges and employed a shotgun metagenomic approach to assess the functional and biosynthetic potential of associated microbiota in Tsitsikamma favus sponges. Clustering of assembled contigs revealed twenty-three putative bacterial genomes, of which, two were identified as representatives of the conserved betaproteobacteria and spirochete species previously identified in Tsitsikamma sponges. It was shown that the spirochete was most likely an obligate symbiont that benefitted the host sponge through possible defence against pathogenic bacteria and/or nutrient acquisition. The putative genome representing the conserved betaproteobacteria was found to be heavily contaminated and further sequencing is required to accurately resolve the genome for functional characterization. Several biosynthetic gene clusters were identified and demonstrated the bioactive potential of Tsitsikamma favus-associated bacteria. A biosynthetic gene cluster was identified on an unclustered contig that included several genetic features that were indicative of possible pyrroloiminoquinone production.

- Description: In a world of economic uncertainty and manifold social problems, South Africa has its own unique challenges of low economic growth, persistent budget deficits that produce increasing government debt and the highest level of economic inequality in the world. The history of injustice and economic marginalisation and the failure of the economy to provide inclusive growth drives an urgent need to address economic inequality through tax policy, placing ever more focus on wealth taxes as a possible solution. There is a hope is that taxing the wealthy may provide the opportunity to redistribute desperately-needed resources to those denied the opportunity to build wealth and who are trapped in the cycle of poverty. Yet, as appealing as a new wealth tax may seem, the introduction of such a tax carries with it a range of risks, not all of which are known. Of great concern is the possible effect on the economy, which, in its vulnerable state, cannot afford any loss of capital and investment. Very little research has been done on wealth tax in the South African context and there is a dearth of literature focusing on the views and perceptions of the wealthy individuals themselves. This qualitative study investigates the merits and disadvantages of a new wealth tax and seeks to identify any unintended consequences that could result from the implementation of a new wealth tax in South Africa, drawing from historical and international experience and primary data obtained from interviews with individuals likely to be affected by such a tax. Having explored the literature and international experiences with wealth tax and having probed the thinking of wealthy individuals who would be the payers of a wealth tax, the study finds that a new wealth tax may contribute towards the progressivity of the tax system, but it is doubtful whether such a tax would provide a sustainable revenue stream that would be sufficient to address economic inequality and there is a risk of causing harm to the economy. Recognising that the motivation for wealth taxes is often driven more by political argument and public perception than by rational quantitative analysis, the study also anticipates the introduction of a new wealth tax and suggests guidelines for the design of such a tax within the framework for evaluating a good tax system. This study informs the debate on wealth taxes in South Africa and contributes to the design of such a tax, should it be implemented.
