- Description: The devastation and destruction caused by natural and man-made disasters have become a global concern, particularly as such disasters affect the most vulnerable in society. The devastation they wreak frequently involves loss of lives and property. Globally, Disaster Management has moved in approach from reactive to proactive. Disaster management is now more than a field of study; it is the application of practices and principles which enable disasters to be managed both prior to and in the aftermath of their occurrence. Disaster risk management is the development approach to Disaster Management. The study addresses the integration of disaster risk management into integrated development planning at the local level in South Africa. The impact of disasters on social and economic development is of special interest. In many instances, resources that have been planned for development have to be diverted for response activities during disasters. Thus, development and disaster risk management are two sides of the same coin and should be dealt with in unison and not separately. There is also now widespread international acknowledgement for the idea of mainstreaming disaster risk management into development planning, particularly at the local level of government. The central argument of this study is that by integrating disaster risk management plans into integrated development plans at the local level, the risks faced by communities can be reduced. Risks can be even further reduced, and development enhanced when communities play an active role in disaster risk management. Within this context, the main objective of the study was to develop a model for integrating disaster risk management plans into integrated development plans at the local level. To achieve this key objective, the study used theoretical and empirical studies. The theoretical aspect focussed on international frameworks and national legislation for Disaster Management. Legislative requirements pertaining to the involvement of communities in integrated development planning were explored, as was the literature on asset-based community development. Empirical research complimented the theoretical research through the use of qualitative methods to collect data. This involved semi-structured interviews with eight government officials involved in provincial, district and municipal Disaster Management programmes, and focus group discussions with sixty ward committee members, so that community viewpoints would be included. The findings of the study reveal that the integration of disaster risk management plans into integrated development plans at the local level can greatly contribute towards reducing the risks faced by communities, especially high-risk communities. The study also revealed that by carefully considering and using community assets, local government could ameliorate the financial effects of Disaster Management and empower communities as first responders. The thesis gives an outline of a model that may be used by local government to integrate risks and community assets into an integrated development plan.

- Description: The search for the cure for cancer is currently a multi-billion dollar industry and the search for the elusive “magic bullet”, i.e. the perfect cancer drug that would interact therapeutically with cancerous tissues while having a minimal effect on healthy cells, is the topic of many research studies in the world today. A large number of novel drugs or drug complexes and conjugates are being synthesized and subjected to rigorous evaluation in the race to find the perfect cure. ECDG (Ethylene diCysteine DeoxyGlucose) seems to have promising cancer targeting ability. Even though this compound has been described in a few publications, we could not find any reference to the current use of ECDG in oncology clinics, either as a therapeutic agent, or as a diagnostic tool for imaging purposes. It was also not possible to purchase pure ECDG anywhere in the world. This prompted us to further investigate ECDG as a possible candidate for cancer targeting research, either as an imaging agent for cancer diagnosis or complexed with an anti-cancer agent for therapeutic purposes. Detailed investigations done in our laboratory can be divided into the following categories: - Development of a synthetic method for ECDG on a multigram scale ; - Purification of prepared ECDG not using the described dialysis method that only allows the purification of small quantities of ECDG (mg scale) ; Detailed investigation of the chemistry involved in the preparation of pure ECDG and its metal complexes ; - Investigation of the stability of ECDG and its metal complexes that is essential data required for any pharmaceutical agent ; - Preparation of ECDG complexes for use as a diagnostic tool, i.e. complexation with 99mTc ; Investigation of the bio distribution of ECDG-ReO complexes ; - Preparation of an ECDG kit as a diagnostic tool for use in oncology clinics. The development of novel aromatic ligands having similar characteristics compared to ECDG, containing an N2S2 chromophore as donor atoms, to further investigate their targeting capabilities, have also been investigated. All intermediates and final compounds were characterized mainly by ESI MS, in some cases IR and NMR whenever available. Successful preparation and purification of ECDG ands its metal complexes was achieved and extensively characterized and evaluated. Efforts directed towards the development of ECDG at NECSA, South Africa, were also rewarded with significant success. Furthermore, significant development regarding the synthesis of two novel compounds with ECDG-like characteristics was also completed.

- Description: The regulation pertaining to a Standard Chart of Accounts (SCOA) for Municipalities was published in 2014 and is applicable to all 257 municipalities and municipal entities in South Africa. The regulation represents a data classification framework or structure and affects all financial management and internal control systems (FMICS) used by municipalities and municipal entities, and affects key business processes within these organisations. Compliance with the SCOA regulation means that the full municipal accountability cycle should accommodate all seven of the SCOA segments, from the budget through transacting and reporting at the transaction level, with all seven of the segments being embedded in the master data table of the municipal FMICS. While the change to technology and systems may be self-evident, the related business change should not be underestimated. This information technology (IT) driven organisational change across the whole municipal environment represents the research topic and key objective of this research study, namely, a strategy towards implementing standard data structures in municipal IT systems. The study followed a pragmatic philosophy using diagnostic reasoning based on an inductive approach, multiple action research methods and a descriptive case study to derive the proposed implementation strategy. The research subjects, which included 25 pilot municipalities, were studied for the duration of the pilot implementation of the strategy with the objective of identifying and utilising the lessons learnt from their experience to fast track the rollout of the strategy to non-pilot municipalities. The study was limited to the local government environment and to South Africa as a geographic area and involved an accidental sample aligned to the implementation project under investigation. The proposed implementation strategy was, however, of a generic nature and is therefore applicable to any other institution or environment engaged in a similar implementation project. The main contribution of the study is an implementation strategy for standard data structures in municipal financial information systems and which consists of seven diagnostics, 17 guiding policies and 48 coherent actions. The strategy was developed and refined during six cycles of data collection, which were conducted at 25 municipalities actively involved in implementing of the standard data structures. The secondary contributions of the research study include three conference papers and one submission to an academic journal.

- Description: Student housing facilities (SHFs) are an integral part of universities’ physical facilities. Therefore, the management of SHF should be seen as part of broader university facility management. Moreover, it can be argued that by understanding the requirements of occupants, facility managers would be able to effectively prioritise the spaces and services required in the SHFs. However, studies from many parts of the world, including Ghana, show that users’ requirements and expectations are not duly incorporated into the management process of university building facilities. As a result, users’, in this case students requirements are not well prioritised by facility managers. Thus, the facility departments are unable to adequately provide and deliver SHF spaces and services to meet students’ requirements. With this in mind, this research aimed to develop a prioritisation and a standard SHF frameworks to enhance the provisioning and management of the on-campus SHF spaces and services at southern Ghana universities. The overarching research methodology was subjective. The qualitative method was adopted for the study. The research was conducted within the southern part of Ghana and limited to five universities. A total of ten focus group discussions were carried out in the five universities. Other sources of primary data were interviews and site visit. The study found that washrooms (toilet and bath), sleeping spaces, kitchens, study areas, libraries, sick bays, computer labs, bookshops, drying areas and discussion rooms as well as electricity, water, security, internet, cleaning services, maintenance services, generators, ventilation (fans), health services, library services, electric sockets, study furniture, refuse collection, pest control and fire extinguishers are extremely important spaces and services that students expect to have in a SHF. Furthermore, it was found that only 3 spaces out of the 10 rated as extremely important were rated as basic, whilst 10 out of the 15 services rated as extremely important received a basic priority rating. However, the study also found that some of these extremely important spaces and services such as study areas, computer labs, kitchens and internet were not provided in some SHFs. The study also revealed that students were generally not satisfied with some of the spaces and services that were provided in the SHFs; dissatisfaction was expressed with: the infrequent water supply; the poor condition of washrooms, i.e. bath and toilet facilities; the lack of study areas and also the condition, adequacy and availability of chairs and tables in the study rooms; the slow response of maintenance departments; the poor standard/quality of cleaning and availability of cleaners; the lack of adequate kitchens and the lack of stable internet connectivity. The study has achieved its aim by developing a prioritisation framework as well as an ideal SHF framework to enhance the provision and management of the on-campus SHF spaces and services at southern Ghana universities. It is recommended that SHFs which do not meet average students’ expected standards should be upgraded to meet such standards. The frameworks developed in the study could be used by facility managers or departments as a guide for effective on-campus SHF management.

- Description: This study seeks to interrogate the effects of 99-year leases on newly resettled farmers, with focus on Zimbabwe’s Fast Track Land Reform programme, shifting from its causes and processes to its variegated outcomes., The focus was on how the leasehold system has impinged on three variables: farm improvement, productivity, and empowerment. Quantitative data was collected from 92 newly resettled farmers randomly selected from three different farming regions in Zimbabwe: Region 2, an agriculturally well-endowed area concentrating on crop production, Region 4, an arid and hot region concentrating on livestock, and Region 5, specialising in sugar cane production under irrigation. To corroborate the survey findings, follow-up interviews and focus group discussions (FGDs) were carried out in these regions. Interviews with purposively sampled experts in agriculture in Zimbabwe were also conducted. Data are presented in charts and graphs as well as detailed descriptions. The study found that the 99-year leases influenced the fortunes of the farmers in different ways. In some areas, depending on the crop grown, the 99-year leases were accepted as a basis for a loan. In other instances, the leases have not been accepted as collateral and this has constrained the farmers’ ability to optimally utilise their farms optimally. Despite a general sense of insecurity, the farmers have shown a willingness to re-invest in the farms., Many improvements such as new accommodation for employees, the erection of fire guards, and the development of water sources are being made on the farms, all pointing to a desire for sustained utilisation of the A2 farms. The researcher proposes that serious effort has to be made towards making the 99-year leases acceptable as collateral for loans because otherwise, in the context of general undercapitalisation among the farmers, their ability to make the medium-scale farms optimally contribute to national accumulation will remain constrained. The form of tenure is related to the empowerment of the farmers, both materially and socially. This is in turn related to the sustainable use of the land and hence to sustainable development in Zimbabwe.

- Description: To make education a profitable enterprise and contributor to social development requires that schools infuse values into schooling as part of the ethical construction of learners and citizenship building. This research used Kampala district as the case study to conduct a qualitative inquiry with grounded theory to examine the integration of values into the management of learners’ discipline in Ugandan schools. Using a sample of 60 participants, the researcher gathered data using personal interviews, focus group interviews, and documentary analysis. Through the analysis of this data, the researcher established that the School Governing Body (SGB), government, educators, missionaries and the community are stakeholders highly involved in directing the process of values integration into learners’ discipline. He also discerned that different schools impart moral, spiritual, academic, aesthetic, social and universal values into the learners. However with the 1963 Castle Report on Education that led to the nationalization and secularization of schools, denominational schools strongly felt that government robbed them of their powers to control and manage schools through the “principle of subsidiarity”. This seems to have led to the gradual erosion of values and breakdown of discipline in the denominational schools as well as the others. The central argument of this thesis is that integrating values into school discipline in Uganda would result into an inclusive education system that supports both theist and atheist attitudes towards formal schooling. Some respondents argued that values should be directly integrated into learners’ discipline while others opposed values integration. Those who supported values integration into school discipline pointed out that it is an integral part of life-education. On the other hand, those who oppose integrating values argued that values integration might be misused to impose secular influences on the learners. The existing avenues of optimal integration of values into school discipline include use of physical punishment and restorative justice, although custodial methods are widely condemned by human rights activists for being too harsh, punitive and retaliatory. Restorative justice methods used include the use of religious and social clubs as well as counseling and guidance. Collective stakeholder participation in school management is also widely used where school management, government, parents and the community take on a collaborative role in empowering and creating an environment for positive discipline. Finally, missionary educators play a significant role in learners’ behavioural modification. The challenges of values integration into school discipline, on the other hand, are policy-related; including poor school administrative styles, failure to define which values to emphasize in disciplinary management, lack of staff motivation and educators’ unethical behaviour. The classroom-related challenges were an over emphasis on academic values that, consequently, turn education into a theoretical rather than a practical exercise. This is compounded by the poor teaching methodologies used like rote-learning due to the problem of dealing with large classes especially in UPE and USE schools and the strict emphasis on an examination-centered syllabus. The social-related challenge observed was the negative influence of the media on young people’s life styles, consequently, leading to permissiveness, aggressive, violent and militant behaviours now common in schools. The study underscored the need to emphasise stakeholder responsibility in school disciplinary management, and the necessity to offer visionary and collegial leadership, identify a common set of values critical to the promotion of life-long learning, promotion of life-education to ensure formation of morally upright learners, and encourage inclusive education (UBUNTUISM). Government should draft a national education philosophy to guide schools in integration of values education, emphasizing secular, moral and religious values, as well as the need for restorative justice, and employing more pragmatic teaching methodologies. There is also the need to create role-models and staff motivation. All these are cardinal remedies in ensuring constructive school discipline. Finally, the central theory that explains the integration is an Integrated Values Framework (IVF) for Positive Discipline (PD). It advocates that discipline is a process of nurturing learners through the provision of inclusive education, life-long learning and citizenship building.

The study underscored the need to emphasise stakeholder responsibility in school disciplinary management, and the necessity to offer visionary and collegial leadership, identify a common set of values critical to the promotion of life-long learning, promotion of life-education to ensure formation of morally upright learners, and encourage inclusive education (UBUNTUISM). Government should draft a national education philosophy to guide schools in integration of values education, emphasizing secular, moral and religious values, as well as the need for restorative justice, and employing more pragmatic teaching methodologies. There is also the need to create role-models and staff motivation. All these are cardinal remedies in ensuring constructive school discipline. Finally, the central theory that explains the integration is an Integrated Values Framework (IVF) for Positive Discipline (PD). It advocates that discipline is a process of nurturing learners through the provision of inclusive education, life-long learning and citizenship building.

- Description: Contemporary debates about development confer a prominent role to citizen participation and decentralization. Growing scepticism about the efficacy of narrowly conceived measures add pressure to reform development both theoretically and in practical terms. There is a greater understanding that ‘traditional’ development approaches and policies need to be reformulated and decentralization and citizen participation have been proposed as remedies to previous development failures. It is frequently argued that citizen participation will improve the efficiency and efficacy of public services. Citizen participation is meant to render local government more accountable and to contribute to deepening democracy, by reinforcing representative democratic institutions with participatory forms. At the same time, decentralization reforms have been proposed as a response to the failures of highly centralized states. From a political perspective, it is argued, decentralization reforms can help the central state gain legitimacy and have been seen as a strategy for maintaining political stability. It has been repeatedly suggested that physical proximity makes it easier for citizens to hold local officials accountable for their performance. From an economic perspective, decentralization can improve the match between the mix of services provided by the public sector and the preferences of the local population. It has also been noted that people are more willing to pay for services that respond to their priorities and that increased competition between local governments generates spaces for more creative responses adapted to local needs. But then, can decentralization and citizen participation live up to the faith and expectations that they have inspired? I argue that the literature commonly over-emphasises the role of citizen participation and decentralization in development and what these processes and reforms can achieve. Much of the evidence is anecdotal in nature and tends to neglect the specific contexts in which these processes take place. Also largely ignored are political economy considerations and a critical exploration of the relationship between these two key words. At best, when their interrelationships are addressed decentralization and citizen participation are conceived as based on a symbiotic relationship. I suggest, however, that the relationship between these two processes is not as straightforward as most of the literature assumes. The meanings of these two key words in current development lexicon are explored and critically assessed. I argue that whether or not the rising prominence of these two words actually means the emergence of a new development agenda is a moot point. It critically depends on the understandings of these ambiguous terms. The thesis adopts a political economy approach. Combined with this is an awareness of the broader historical and socio-economic context in which citizen participation and decentralization take place. The thesis applies these ideas triangulating diverse research methods and data sources. It combines a literature review and documentary analysis, a survey conducted with municipal authorities and civil society organizations in the Eastern Cape as well as structured interviews with Ward councillors and with key informants. From a theoretical perspective, the study lays a foundation for understanding the relationship between development policies outcomes and the nature of citizen participation and decentralization in developing countries. This, in turn, provides a basis from which citizen participation and decentralization in South Africa can be assessed and understood. The thesis presents evidence from a case study of the Eastern Cape, South Africa. By revealing how different dimensions of decentralization and citizen participation operate and intersect, the findings demonstrate, that contrary to common knowledge, citizen participation and decentralization are frequently at odds. Moreover, contrary to frequent statements, the research also shows that opening new spaces for participation in decentralized local governance can result in fewer changes and disappointing results at best, undermining the transformative potential of the concepts of participation and decentralization.

- Description: Approximately sixty percent of Africans depend on rainfed agriculture for their livelihoods. South Africa is evidenced to be susceptible to inclement climate which impacts on rural livelihoods as well as on farming systems. While South Africa is considered to be food sufficient, it is estimated that approximately 35percent of the population is vulnerable to food insecurity. Therefore with the application of surveys and interviews this study investigates the factors influencing household, subsistence and small-scale farmer perceptions of vulnerability to climate variability as well as the determinants of adaptive capacity. A sample of 308 households is surveyed and four focus group discussions are administered in Ngqushwa Local Municipality as a case study. Furthermore, the study also focuses on the biophysical changes or factors (scientific analysis of the prevailing climatic regimes–rainfall trends); the interrogation of the impact of food systems on both food prices as well as its implications on food sovereignty. The study also interrogates the relationship between crop yield and rainfall data over a 30-year period. Therefore the study adopts a mixed method approach to ensure triangulation. The study finds that rural communities are able to perceive climate variability and its related changes as well as its negative impact on crop production, food access and availability. The perceived rainfall trends also corroborate this Pearson product-moment correlation coefficient reveals that there is a strong correlation between crop yields and rainfall (r = 0.69). Meteorological analyses also show that the rainfall trend has been significantly variable over 112 years (1900 - 2011) with several dry spells threatening the subsistence and small-scale farmers’ sustainable livelihoods. The food systems pose threats to food safety, food security and historical food sovereignty for the rural community of Ngqushwa Local Municipality. Adaptive capacity is greatly impaired by the lack of co-ordination of adaptation strategies, which communally benefit the majority of the farming respondents in the study area. Therefore vulnerability to climate variability impacts on the ability of the respondents to achieve food security. The study also finds that there is perceived competition between the farmers and wild life for the natural resources. The respondents’ perception is that climate variability and change is responsible for such competition. The study recommends that the national, provincial and local governments must foster a new food production model that is not based on the agro-business model and its attendant technologies but on one that is based on robust agro-ecological farming techniques which enhance adaptive capacity; which foster food safety; which promote food sovereignty; and which reduce vulnerability in a sustainable manner. Given the extent of climate variability in the study area the restoration of the NLM weather station infrastructure can also aid the farmers in taking advantage of a robust early warning system for better estimation of climate trends which enhance crop production.

- Description: Organizations face challenges constantly owing to limited resources. As such, to take advantage of new opportunities and to mitigate possible risks they look for new ways to collaborate, by sharing knowledge and competencies. Coordination among partners is critical in order to achieve success. The segmented South African public sector is no different. Driven by the desire to ensure proper service delivery in this sector, various government bodies and service providers play different roles towards the attainment of common goals. This is easier said than done, given the complexity of the distributed nature of the environment. Heterogeneity, autonomy, and the increasing need to collaborate provoke the need to develop an integrative and dynamic coordination support service system in the SA public sector. Thus, the research looks to theories/concepts and existing coordination practices to ground the process of development. To inform the design of the proposed artefact the research employs an interdisciplinary approach championed by coordination theory to review coordination-related theories and concepts. The effort accounts for coordination constructs that characterize and transform the problem and solution spaces. Thus, requirements are explicit towards identifying coordination breakdowns and their resolution. Furthermore, how coordination in a distributed environment is supported in practice is considered from a socio-technical perspective in an effort to account holistically for coordination support. Examining existing solutions identified shortcomings that, if addressed, can help to improve the solutions for coordination, which are often rigidly and narrowly defined. The research argues that introducing a mediating technological artefact conceived from a virtual community and service lenses can serve as a solution to the problem. By adopting a design-science research paradigm, the research develops a model as a primary artefact to support coordination from a collaboration standpoint. The suggestions from theory and practice and the unique case requirement identified through a novel case analysis framework form the basis of the model design. The proposed model support operation calls for an architecture which employs a design pattern that divides a complex whole into smaller, simpler parts, with the aim of reducing the system complexity. Four fundamental functions of the supporting architecture are introduced and discussed as they would support the operation and activities of the proposed collaboration lifecycle model geared towards streamlining coordination in a distributed environment. As part of the model development knowledge contributions are made in several ways. Firstly, an analytical instrument is presented that can be used by an enterprise architect or business analyst to study the coordination status quo of a collaborative activity in a distributed environment. Secondly, a lifecycle model is presented as meta-process model with activities that are geared towards streamlining the coordination of dynamic collaborative activities or projects. Thirdly, an architecture that will enable the technical virtual community-centric, context-aware environment that hosts the process-based operations is offered. Finally, the validation tool that represents the applied contribution to the research that promises possible adaptation for similar circumstances is presented. The artefacts contribute towards a design theory in IS research for the development and improvement of coordination support services in a distributed environment such as the South African public sector.

- Description: The remnant life monitoring of creep loaded high temperature and pressure components in power stations is critical to ensuring their safe and cost effective operation as failures can have severe consequences. Effective creep life condition monitoring allows for optimising component life predictions and subsequent plant maintenance decisions. In South Africa many power generation stations have been in operation well beyond their 30 year design service life, as such knowledge of the remnant creep life of high temperature and pressure components, such as steam pipelines, becomes of utmost importance. Techniques for the remnant creep life assessments of critical high temperature and pressure components must therefore be as effective as possible. The common and well accepted in-situ inspection technique for assessing creep damage in steam pipes is by the metallographic replication technique. The technique is however limited to the outer surface of the pipe, without information on damage within the wall. This research will illustrate a means of obtaining a sample for creep life analysis with depth through the wall of a pipe, as wells as an alternative technique for the repair of the sample retrieval site. A sample retrieval technique was developed that would retrieve a small diameter cylindrical sample from a cored blind hole for creep analysis by visual creep void assessment or by the small punch creep test. The small punch creep test requires only a small diameter thin disc of material for testing for which its results are comparable with conventional uniaxial creep testing which requires a much larger sample of material. The smaller sample requirement of the small punch creep test therefore allows for a vastly reduced invasive sample retrieval operation and consequently smaller repair size area. Also the fact that the sample is retrieved from a blind hole is advantageous since the pipe wall is not penetrated which would require full plant shutdown. A friction welding technique was identified as an alternative to traditional arc fusion welding for the repair of the sample retrieval site, this technique being the Friction Hydro Pillar Processing technique. Friction Hydro Pillar Processing is a solid-state welding technique and as such has a number of inherent benefits over arc fusion welding as the weld is performed below the melting temperature of the material. From a process point of view Friction Hydro Pillar Processing is ideally suited for automation, has virtually no fumes generated, minimal distortion is experienced and no spatter has to be removed afterwards. The technique has yet to see industrial application and as such development of suitable process parameters was undertaken. Finally, to apply the sample retrieval and repair operations in-situ to a steam pipe in a power plant suitable equipment was developed. Existing friction welding equipment is generally bulky workshop based equipment and is unsuitable for on-site work due to its size and weight. Therefore development of dedicated equipment was required to enable Friction Hydro Pillar Processing to be applied to steam pipes within a power plant environment.

- Description: Marine ecosystems are experiencing rapid changes due to climate change. The associated temporal and spatial changes in resource distribution impacts on the foraging behaviour of marine top predators. If these changes negatively affect the ability of marine predators to forage efficiently, there may be dire consequences for their populations. However, evidence of foraging plasticity during adverse conditions, or generalist foraging behaviour, can allow inference about the resilience of species to environmental change and provide essential knowledge towards effective and proactive conservation measures. I examined plasticity in the trophic ecology of 12 marine predator species breeding on Marion Island, southern Indian Ocean, over three years (2015 – 2018), a period characterized by pronounced environmental variability. Firstly, I correlated behavioural states inferred along the GPS tracks of incubating wandering, grey-headed, sooty and light-mantled albatrosses to environmental variables that are indicative of biologically productive oceanographic features. Secondly, I analysed δ13C and δ15N blood values in 12 marine predator species (the afore-mentioned albatrosses as well as king, gentoo, macaroni and eastern rockhopper penguins, northern and southern giant petrels and Antarctic and sub-Antarctic fur seals) over two seasons: summer and autumn. My results revealed that the foraging behaviour of all the species is, to some degree, either plastic (temporally variable isotopic niche) or general (large isotopic niche which remained similar over time), except for the king penguin (small isotopic niche which remained similar over time), a known foraging specialist. Furthermore, despite their dynamic foraging behaviour, resource partitioning among the predators was maintained over time. Due to the ease and relatively low cost of collecting tissues for stable isotope analysis it has the potential to be a powerful tool to monitor the trophic ecology of marine predators. I thus used my simultaneously collected dataset of GPS tracks with the stable isotope blood compositions to investigate some of the assumptions underlying the inferences made from marine predator δ13C and δ15N blood values. I reconstructed species- and guild- specific δ13C and δ15N isoscapes for eight seabird species. Following this, I coupled individual-based movement models of northern giant petrels with global marine isotope models to explore the sensitivity of tissue δ13C values to a range of extrinsic (environmental) and intrinsic (behavioural, physiological) drivers. My results demonstrate the strong influence of reference isoscapes on the inference of stable isotope compositions of marine predators. Furthermore, I show that caution should be used when using non-species-specific or temporally inaccurate isoscapes. I furthermore demonstrate that biological interactions, such as competition for food resources, either past or present, as well as spatio-temporal distribution of food patches strongly influence the foraging behaviour of marine predators. These findings highlight the importance of integrating biological interactions in species distribution models which are used to predict possible distributional shifts of marine predators in the context of global changes. My thesis further developed previously available methods and presents a novel approach to investigate sources of variance in the stable isotopic composition of animals’ tissues.

- Description: Much emphasis has been placed on democracy, equality and human rights since the dawn of the democratic South Africa in 1994. Efforts to align the South African education system with the democratic principles of the Constitution, not only in terms of eradicating past racial divides, but also in terms of accessibility to learners who experience barriers to learning are eminent. The South African Government issued various policies to ensure quality, equitable and accessible education for all, irrespective of ability. Theoretically, no learner should therefore being discriminated against on any basis. In practice, however, thousands of learners, especially those who experience barriers to learning are denied the opportunity to receive meaningful development opportunities in many mainstream primary schools, resulting in their early drop out from school without having acquired the basic skills and knowledge to become self sustainable members of their communities. With the adoption of Bronfenbrenner’s ecological model as theoretical framework for this study, the primary aim of this qualitative investigation was to investigate and describe how effective learners who experience barriers to learning are managed in mainstream primary schools and to develop a framework for the creation of more sustainable management systems to ensure that the needs of all learners are met. The findings of the empirical investigation revealed that most learners who experience barriers to learning are currently not managed effectively in mainstream primary schools due to factors situated across the whole education system, to the detriment of learners who experience barriers to learning. Based on the findings of the empirical investigation, this study proposes a framework which will ensure the effective management of learners who experience barriers to learning in mainstream primary schools. The framework include recommendations to be implemented across all layers of the ecological system.

- Description: Much emphasis has been placed on democracy, equality and human rights since the dawn of the democratic South Africa in 1994. Efforts to align the South African education system with the democratic principles of the Constitution, not only in terms of eradicating past racial divides, but also in terms of accessibility to learners who experience barriers to learning are eminent. The South African Government issued various policies to ensure quality, equitable and accessible education for all, irrespective of ability.

- Description: AIDS is one of the most destructive diseases humankind has ever faced and also brings with it profound social, economic and public health consequences, making it one of the most serious health and development challenges in the world today. Zimbabwe, situated in southeastern Africa, is not spared from the pandemic. It continues to be one of the Sub-SaharanAfrican countries mostly heavily impacted by the AIDS epidemic, with almost 1.2 million people infected and over 1.1 million orphans. It ranks, therefore, as fifth highest in the world in the impact HIV and AIDS has had on the country. The most effective response has been to introduce programmes to reduce the number of new infections. Recent research has demonstrated treatment as a preventative measure to be very effective. This approach involves targeting those who are infected so that they are not able to transmit the disease. The decision that has to be made by an infected person, however, is whether to look for traditional treatment, conventional treatment or a combination of the two. Herbal medicine use is becoming very common in many countries, especially in the developing world, where public health safety has become a concern. It has become common to use herbal medicine concomitantly with allopathic or conventional medicine. The present study focused on investigating perceptions leading to the choice of treatment with the traditional alternative medicines (TAM) as (a)/n alternative or compliment to the conventional or allopathic option. This is a qualitative study that explores and describes participant’s perceptions, beliefs, attitudes and feelings around the use of traditional medicine, within the context of the Integrative Behaviour Model (IBM). Data was collected from 20 people living with HIV and AIDS from urban and rural settings of different ethnicities (Shona and Shangani). The data analysis was informed by The Interpretive Phenomenological Analysis with the aid of NVivo (V.10), a computer-assisted Qualitative Data Analysis Software. As predicted by the IBM, both perceived individual and environmental factors were found to be key in influencing decision-making on the use of TAM by people living with HIV and AIDS. Although there were a number of incidents in which either individual or environmental factors were perceived as independently influencing the TAM-use decision-making process, there was a lot of mutual influence between the environment and the individual. Such mutual causation was abstracted as reciprocal determinism. The IMB model assumed a unidirectional causation in which the environment could affect the individual factors. While the present study identified and demonstrated these environmental effects on the individual, it also identified and presented a reverse causation in which the individual would also affect the environment with respect to motivation for TAM use. Individual factors were psychological properties that drove the individual to use TAM. Attitude, social influence and personal agency emerged as the three dimensions of individual factors. Attitudes helped in identification of orientations that located objects of thought on dimensions of judgment about the use of TAM. Social influence explained social pressure experienced and expected regarding the use of TAM. The study demonstrated the importance of both the descriptive and injunctive norm with participants indicating that they perceived important others to be using traditional medicine and that they felt perceived expectations from others to do the same and hence the motivation to comply. Personal agency pointed to the participants’ capacities to originate and direct actions for the purposes of TAM use. All these constructs were found to be very important as perceived determinants of the behavioral intentions of people living with HIV and AIDS to use traditional medicines. In experiential attitude, generally the respondents showed more perceived positive evaluations of pleasurable experiences in their use of traditional medicines. However, there were other outcome evaluations that seemed to be ambivalent and which appeared to cause a lot of tension. The comprehension of experiential attitude was found therefore found to be trichotomous rather than dichotomous as per the IBM. The effects of the instrumental attitude were revealed in the ratings of the extent to which the use of traditional medicine was perceived as useful or rewarding, with the study revealing high ratings of usefulness. It becomes clear, therefore, that for people living with HIV and AIDS social influence, perceived attitudes and personal agency are important decision-making factors in their use of traditional and alternative medicine. Efforts towards education, integration and behaviour change programmes should design messages targeting these behavioral determinants. Understanding of these perceived determinants is crucial to influencing policy as well as the adoption of health practices through education, marketing and other modes of health promotion.

- Description: This research study has emerged as a result of my concern regarding the apparent low self-efficacy amongst initial teacher education students in my mathematics education classes. It also reflects a reported renewed interest in values, and the promotion of excellence in education. The effects of a values-based approach to mathematics education towards improving students’ self-efficacy and promoting excellence have been investigated, grounded within my ontology of excellence in mathematics education, which incorporates the values of respect, fairness, accountability, honesty and compassion. An inquiry-based teaching and learning approach formed the framework within which the study took place. Notions of ‘new scholarship’, premised on the view that teaching is about engagement in participatory learning, and the development of communities of creative students, provided the theoretical framework. Both quantitative and qualitative data gathering methods were used. Data-collection tools included affective-disposition statements, interviews, journal entries, as well as a video recording of a mathematics education lesson. The quantitative and qualitative data generated suggest improved levels of self-efficacy amongst the students who participated in the study. The data also suggest that a valuesbased approach to teaching can be used as an effective approach by mathematics teachers – and mathematics teacher educators – for the purpose of promoting the pursuit of excellence. As teacher education worldwide is currently characterised by a lack of vitality in teacher preparation (Grossman, 2008), the findings of this study should provide insights for teacher educators, teachers and policy makers who wish to promote mathematics self-efficacy, excellence and facilitate enhanced vitality within the teaching profession.

- 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: The assessment of the motivational value of rewards in the world of work is interesting but difficult to understand. Variations in research reports and inadequate comprehension of the efficiency and motivational value of rewards have brought about confusions, controversies and contradictions among authors, researchers, consultants and practitioners in the field of Industrial and Organisational Psychology (Mangham, 2007; Muula, 2006; Muula & Maseko, 2005; Palmer, 2006; World Bank, 2004). As a consequence, organisations are applying theories and models of motivation selectively depending on their beliefs, ideological framework of values and assumptions (Dzimbiri, 2009). The study was therefore carried out as a positive contribution to the existing knowledge and debate on the motivational value of rewards for health professionals in the public health sectors of the developing countries. Through a systematic sampling method, 571 health professionals were sampled for the study. Data were collected through the use of a self-administered questionnaire which was composed based on the data collected from desk research/literature review, focus group discussions and interviews. The findings of the study revealed that the Malawi‟s Ministry of Health (MoH) is failing to attract, motivate and retain health professionals; there is perception of inequity of the rewards among the health professionals; health professionals develop coping strategies to supplement their monthly financial rewards; health professionals engage in corrupt practices to supplement their monthly financial rewards; and there is erosion of industrial democracy in the Malawi‟s Public Health Sector. While the statistical testing of the hypothesized model proved a lack of fit between the variables, the statistical testing of the re-specified model suggests that there is a positive relationship between financial rewards and reward-related problems being faced by health professionals in the Malawi‟s MoH. Through the Structural Equation Modeling (SEM) exercise, an inverse (negative) relationship between financial and non-financial rewards was deduced, and scientifically and graphically demonstrated. Both the re-specified and graphical models symbolize a pragmatic departure from the theoretical model whose authors (Franco, Bennett, Kanfer & Stubblebine, 2004) are largely inclined to the use of non-financial rewards and suggest that financial rewards should be used with caution. These findings also reject the Herzberg‟s two factor theory (Herzberg, 1960) which claims that financial rewards (salaries) are not a motivator. The major recommendations of the study are that the Franco et al.‟s (2004) model should be adopted and adapted in the Malawi‟s MoH with the view that the value of both financial and non-financial rewards (as motivators) varies from individual to individual due to individual differences and prevailing factors/forces in both the work environment and wider society in which the MoH operates; a hybrid reward system combining the strengths of time-based, performance-based and competence-based reward systems should be developed and implemented; the results of scientifically testing the re-specified model and the inverse (causal) relationship established between financial and non-financial rewards (as demonstrated in a graphic model) should be re-tested with other samples in the public health sectors of the developing countries; and the motivational value of non-financial rewards should be scientifically established and compared with the motivational value of financial rewards used independent of each other in business organisations to make an objective conclusion on the rewards-motivation debate.

- Description: Nurses are confronted with numerous work-related stressors that can result in burnout. This can contribute to absenteeism and high turn-over rates in the nursing profession. A review of the literature indicated that psycho-educational interventions to increase resilience could be an effective way of addressing this problem. The study aimed to develop a positive clinical-psychology approach to increasing resilience in State employed nurses. The study used a mixed-method approach to determine the current psychological functioning of a sample of 87 nurses. Quantitative data on personality traits, character strengths and levels of resilience were obtained, using the NEO PI-R, VIA – IS, and Resilience Scale. Qualitative data on the coping responses of nurses were obtained through the thematic analysis of focus groups. These data were integrated to create a positive clinical psychology conceptualisation of resilience and to develop therapeutic guidelines for a group psycho-educational intervention. The results of the study indicated a struggling psychological profile. This was defined as the ability to deal with work-related stressors – but with the potential risk of developing symptoms of burnout. The moderate levels of resilience were attributed to elevated character strengths in the sample. The distribution of personality traits indicated that the nurses in the sample were at risk of developing burnout; and this prevented them from flourishing. These data were synthesised to create therapeutic guidelines for developing resilience aimed: (1) increasing emotional stability and invulnerability; (2) increasing agreeableness; and (3) increasing conscientiousness. These guidelines were based on the personality traits that were deemed to negatively impact the resilience of the nurses. These personality traits were correlated with several character strengths that displayed strong relationships with resilience. This indicated that resilience could be developed through the cultivation of the following character strengths: perspective; perseverance; fairness; forgiveness; leadership; love; zest; hope; curiosity; and appreciation of beauty and excellence. These character strengths were identified to facilitate the positive adaptation of the personality traits identified in the therapeutic guidelines. A group psycho-educational intervention was developed, using the positive clinical psychology conceptualisation of resilience. The literature was reviewed to identify techniques to cultivate the ten character strengths specified in the therapeutic guidelines. These techniques were adapted to create experiential learning processes for the intervention. This psycho-educational programme can be applied as a secondary and tertiary intervention. It can be used to increase resilience to prevent burnout among nurses. It can also be used to psychologically empower nurses that have existing symptoms of burnout.

These guidelines were based on the personality traits that were deemed to negatively impact the resilience of the nurses. These personality traits were correlated with several character strengths that displayed strong relationships with resilience. This indicated that resilience could be developed through the cultivation of the following character strengths: perspective; perseverance; fairness; forgiveness; leadership; love; zest; hope; curiosity; and appreciation of beauty and excellence. These character strengths were identified to facilitate the positive adaptation of the personality traits identified in the therapeutic guidelines. A group psycho-educational intervention was developed, using the positive clinical psychology conceptualisation of resilience. The literature was reviewed to identify techniques to cultivate the ten character strengths specified in the therapeutic guidelines. These techniques were adapted to create experiential learning processes for the intervention. This psycho-educational programme can be applied as a secondary and tertiary intervention. It can be used to increase resilience to prevent burnout among nurses. It can also be used to psychologically empower nurses that have existing symptoms of burnout.

- Description: The extended role of today’s pharmacist with the emphasis on patient-focused care has highlighted the need for increased exposure of undergraduate pharmacy students to experiential learning in patient-centred environments, and additional skills development in therapeutics, problem solving and clinical decision making. At the Nelson Mandela Metropolitan University (NMMU), final year pharmacy students complete a university-coordinated, hospital-based, structured experiential learning programme (ELP) for the exit-level module, Pharmacology4. However, the students consistently experience difficulties in the application of pharmacological knowledge during the transition from lecture-based learning to the patient-focused clinical setting. The student population at the NMMU is diverse, with varied cultural, ethnic, language and secondary level education backgrounds, as well as different learning preferences and approaches. The extent to which these factors affect academic achievement in the experiential learning environment is unknown. Central research question The central research question for this study was therefore, “What would be the effect of an intervention aimed at supporting undergraduate pharmacy students during clinical placements, on academic achievement in, and student attitudes towards, experiential learning programmes (ELP)?” In order to explore the research question, several factors which may influence academic achievement in ELPs were investigated, namely: academic achievement (pre-university, in the BPharm programme and, in pharmacology); the admission route into the BPharm programme and the subsequent rate of academic progression; English reading comprehension ability; learning styles; problem solving ability; the extent to which students are prepared for application of knowledge in the ELP, in terms of assessment methods used prior to the final year and previous pharmacy work-based experience. In addition, the students’ lived experience of the ELP was explored, and the need for, and nature of, an intervention was determined. The research was based in a pragmatic paradigm, using an advanced mixed methods approach. An intervention-based, two-phase, quasi-experimental design was employed with an initial exploratory Preliminary Phase (in 2013) preceding the larger experimental framework (Phases One and Two, in 2014 and 2015 respectively). The research design was primarily quantitative, with pre- and post- testing conducted before and after the ELP. The ELP was completed by the comparator cohort in Phase One and the experimental cohort in Phase Two. Supplementary qualitative data was collected before, during and after the ELP. The intervention, in the form of supplementary academic support sessions, was developed from the qualitative data using an iterative approach, and implemented during the ELP in Phase Two. Attitudes and expectations of the students towards the hospital-based ELP were generally positive and realistic. Areas of concern included the difficulties experienced in the application and integration of pharmacological knowledge, both in the clinical setting and the clinical case study-based assessments; students feeling overwhelmed, inadequate and inferior in the clinical environment, compounded by an absence of clinical pharmacists as role models; and feeling unprepared for patient-focused care. The qualitative data strongly supported the need for supplementary academic support sessions. The intervention was developed and implemented in Phase Two, using patient case-based, active learning strategies. The majority of students (91.0%; n = 104) reported improved case analysis skills. A statistically significant (p = .030, Cohen’s d = 0.34) improvement was noted in the summative Pharmacology4 assessment marks obtained by the experimental cohort post-intervention, although of small practical significance. Predictors of academic achievement in the ELP were found to be language, specifically English reading comprehension skills, academic achievement in the BPharm programme and pharmacology, the university admission score, the rate of academic progression, and problem solving ability. Previous pharmacy-based work experience and assessment questions requiring application of knowledge were also found to influence achievement in the ELP. The need for an intervention in the form of supplementary academic support sessions was confirmed. The intervention was subsequently developed and successfully implemented, with student-reported self-perceived improvements in patient case analysis skills. These positive findings were supported by quantitative data which showed a statistically significant improvement in academic achievement in the ELP. Several predictors of academic achievement in the ELP were identified, and invaluable insight was gained into the nature of the difficulties experienced by pharmacy students in the transition from lecture-based learning to experiential learning in patient-focused environments.

- 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: Smart meter implementations are still in their infancy in many African countries. This is evident by the lack of research on the subject in the African context. Most of the research studies are either Eurocentric or US-centric. Although these studies are important and informative, they might not address the African challenges in context. Hence, South Africa was chosen as the testbed for an investigation that addresses the apparent knowledge gap. This study set out to formulate a framework for planning considerations in the implementation of smart meter technology within South Africa. Through extensive literature review and analysis, the technology acceptance model (TAM) was chosen as a foundational framework for this study. Although TAM is widely used for researching technology acceptance and use, its applicability was found to be inadequate in explaining customer centric factors in smart metering. Therefore, it was supplemented with factors from the theory of reasoned action (TRA), the theory of planned behavior (TPB), privacy calculus theory (PCT), as well as the unified theory of acceptance and use of technology (UTAUT). A total of 11 consumer-centric factors were identified, and these were statistically analysed using the structural equation modelling technique (SEM). Ten (10) consumer-centric factors was found to be significant. These were attitude, perceived value, monetary cost, privacy risk, perceived ease of use, perceived usefulness, facilitating conditions, social norms, trust in technology and behavioral intention. Hypothesis testing confirmed that, not one acceptance model could adequately be used to identify and explain the consumer-centric factors that can be incorporated for planning considerations for smart meter implementation in South Africa. It was further observed that the consumer-centric factors such as environmental issues, security, reliability and health issues that were important in developed countries were not deemed so in South Africa. From a methodological perspective, the study attests to contextual localised application as opposed to universal meaning and measurement invariance when incorporating planning consideration for smart meter implementation in South Africa as compared to European countries and the United States of America. Finally, the findings hold some practical implications, as they showed the practical utility of the model in predicting the consumer-centric factors that can be incorporated for planning considerations. In support, the Business Model Canvas (BMC) was found to be a useful tool in deriving and reporting on the formulation of planning consideration guidelines. Using the BMC, five planning consideration guidelines were derived: customer segmentation, partnerships, benefits communication, value identification and customer attitude. These planning considerations will allow smart meter providers to identify their customers, partners and value propositions they might need to offer consumers to facilitate a higher smart meter acceptance and use. The proposed planning consideration guidelines can practically be used by policymakers and regulators for several aspects for future pervasive technology acceptance studies. This research has, therefore, created a platform for further research in the smart technology domain while providing a usable predictive framework for the identification of consumer-centric factors and formulation of planning considerations guidelines for smart meter implementation within the South African context.
