- Description: Few studies have investigated the factors that influence roadkill occurrence in developing countries. In 2013, we monitored a 100‐km section of the road (comprising the R572 and R521 regional highways and the D2662) that pass through the Greater Mapungubwe Transfrontier Conservation Area in South Africa, to assess the possible factors influencing roadkill. Over a period of 120 days, and across the three ecological seasons, we recorded 981 roadkills (rate = 0.08 roadkill/km/day) from four vertebrate taxonomic groups. We generated predictive models of roadkill from one combined data set that considered eight variables identified from the literature as potential correlates of roadkill. The model that included the distance of the fence from the road, habitat type adjacent to the road, and the presence of a hill in the road (i.e., elevation) or a bank on the side of the road best explained roadkill occurrence.

- Description: The motor industry is a critical component of South Africa’s economy. It is also an industry that has become intensely competitive with a large variety of vehicle brands on offer for buyers to choose from. Given the competitive nature of this environment, Original Equipment Manufacturers (OEM’s) are constantly under pressure and have to consistently review and develop new strategies to keep their brands relevant in the market. The purpose of the study was to gain insight into customer preferences and specifically vehicle purchasing behaviour, and to establish if brand factors and personal factors influence consumer buying behaviour for particular vehicle brands. An empirical investigation was embarked on using a self-administered questionnaire with a seven-point Likert scale. Convenience sampling was used and resulted in the return of 215 usable questionnaires. The reliability of the measuring instrument was confirmed via acceptable Cronbach’s alpha coefficients. Descriptive statistics were used to analyse the data collected. The main findings indicate that numerous factors influence buyers’ behaviour when purchasing a vehicle. However, Quality, Safety and Price had the biggest influence on the buyer’s decision making when choosing a particular vehicle brand. Based on the findings, recommendations are made to dealers and OEM’s. These recommendations are practical and also linked to previous research as presented in the literature. Dealerships and OEMs should therefore take cognizance of these results and improve on these factors to influence vehicle buying behaviour. These factors should also be used as strong marketing components when advertising and selling vehicles. The value for money provided by vehicles should be emphasised. The link between Quality, Safety, and Price should therefore be accentuated.

- Description: Electronic Medical Record (EMR) systems have been identified as having the potential to improve health care and allow the health care sector to reap a number of benefits when implemented successfully. These benefits include enabling quick and easy access to patient files and also reducing the problem of misplaced or lost patient files. Such EMRs allow for patient records to be up to date, provided that health care practitioners capture standard and consistent data in the relevant fields. In Africa, there are only a few countries that have successfully implemented EMR systems due to social and technological challenges. Social factors include lack of computer skilled health workers, lack of adequate training, physician’s resistance to shift from using paper records to electronic records, either due to complex systems or the fear of being replaced by the systems. On the other hand, the technological factors include lack of Information Technology (IT) and clinical resources, lack of internet access, financial barriers to purchase the necessary technological hardware and implementation costs. A few South African health care institutions have implemented EMR systems, however, most of the public health care facilities still make use of a manual system to capture patient information. In the case where public health care facilities do have an EMR system implemented, there are problems with the consistency of the data that is captured. The inconsistency is caused by the different understandings that the health care professionals have regarding the importance of capturing the necessary information that is collected at various points in health care institutions, thus affecting data quality. For the successful implementation and use of EMR systems, everything within the health care organisation should be integrated. In other words, the steering committee and workgroup, the equipment, the product, the processes, the system and the facility design and construction should be incorporated to work together. The common problems identified in literature regarding data quality in EMRs include misspelled words, inconsistent word strings, inaccurate information entered on the record and incompleteness of the record. These problems lead to poor quality information, lack of accessibility of the record, poorly organised notes and inaccurate information about the patient. The South African strategy aims to implement a National Health Insurance (NHI) which will provide citizens with equitable access to health care. For the successful implementation of the NHI strategy, South African health care sectors should address the barriers which were identified and learn from other African countries that have successfully implemented EMR systems and had positive outcomes. Therefore, this study investigates how data quality can be improved on electronic medical records in public health care in South Africa? The qualitative research methodology approach was used for this study. Interviews were conducted with eight health care professionals at Klerksdorp, in the North West province to obtain data regarding the factors they would deem important for the improvement of data quality in EMRs. The Data Quality Framework (DQF) was applied in this study and six dimensions were identified as the factors to improve data quality. These dimensions include completeness, accuracy, consistency, conformity, timeliness, and integrity. From the analysis of the interview responses, it was discovered that there were, in fact, data quality issues experienced at the public health care facilities of South Africa. A need was identified for the use of data quality assessment tools and solutions to address the data quality issues or challenges that health care practitioners are faced with during their daily jobs. Seven barriers were also identified as having an impact on the successful implementation of EMRs at health care institutions. These barriers, together with the data quality issues, influence the successful use of EMRs and should not be overlooked. From these barriers the study developed seven Critical Success Factors which can be used by the National Department of Health to improve the quality of EMRs. , Thesis (MCom) -- Faculty of Management and Commerce, 2019

- Description: Over the years, there has been an increased research interest in the field of family business because of the entrepreneurial potential of these businesses, as well as their potential to outperform non-family businesses. However, a lack of longevity and a lack of transgenerational success has hindered the potential of family businesses. The widely recognised Successful Transgenerational Entreprenuership Practices (STEP) framework highlights that eight familiness resource pools influence performance outcomes and ultimately the transgenerational potential of family businesses. These eight family resource pools are: leadership, networks, capital, decision-making, culture, relationships, governance, and knowledge. Given the lack of knowledge that exists concerning the nature of familiness resource pools among family businesses in a developing country context, the purpose of this study was to investigate the familiness resource pools of two South African family businesses, so that the nature of these pools in a developing country can be described and potential sources of heterogeneity highlighted. Specifically, the study analyses these familiness resource pools as a source for creating value across generations and enhancing the longevity of family businesses. The study followed the research methodology guidelines and protocols of the global STEP project by adopting an interpretivistic paradigm and a qualitative methodological approach. The case study methodology was used, and two successful multigenerational family businesses operating in the South African automotive industry were selected by means of criterion sampling. The data was collected by undertaking personal interviews with key members of these family businesses, and the data analysis involved undertaking deductive content analysis using Atlas.ti and a comparative analysis. The findings of this study suggest that the familiness resource pools among family businesses in a developing country are similar in some respects to those of family businesses in a Western context. However, they differ in other respects, and differ from each other. As such, the existence of heterogeneity in family businesses and particularly among the familiness resource pools, is confirmed. The findings also identify several similarities and differences between the extant literature and real world evidence concerning the nature of the familiness resource pools in family businesses. In general, they suggest that real world evidence is often similar to that reported in extant literature with only some discrepancies being identified. The current study provides a better understanding of the nature of the familiness resource pools in a developing country, and has enhanced the knowledge of family businesses in this regard. In describing the eight familiness resource pools of two successful South African family businesses in the automotive industry, this study provides valuable insights into the nature of the resource pools of successful family businesses in a developing country context and highlights their heterogeneity. The findings also prove of value to the participating family businesses, because by highlighting shortcomings and differences between them, changes and improvement can be made where necessary.

- Description: Within the growing body of literature on sexuality education in South Africa, researchers have highlighted how teachers may face, or themselves be, barriers to the implementation of rights-based comprehensive sexuality education. Important issues with regard to educators are: firstly, the social and discursive space within which educators are located; and secondly, the complex emotional and psychic investments that educators take up within particular discourses and practices. This paper explores, through a psychosocial reading of an interview extract with a particular educator based in the Eastern Cape of South Africa, how discursive and psychic concerns are sutured within the complex subjectivity of the educator as the medium for sexual education in schools. Specifically, it highlights the numerous ways in which feminine sexuality and desire may be avoided, denied and silenced. Even when feminine desire is specifically evoked as in this case, it is done so in a way that ensures social and cultural respectability, thereby reproducing shame narratives that form and maintain traditional gender discourses. Our analysis demonstrates how engaging with educators as subjects with their own sexual history and psychic dynamics, and as individuals with raced, gendered and classed identities, is a potentially transformative perspective for effective sexuality education.

- Description: Since the identification of financial development for economic growth by Schumpeter (1911), the importance of financial development has been emphasised. However, the nature of the relationship is unclear, whether financial development is demand-following, supply-leading, feedback relationship or no causal relationship with economic growth. The revolution of the relationship between finance and economic growth has left a void of the exact nature of the relationship and importance of financial development in literature and empirical evidence. In addition, the variation of the nexus between financial development and economic growth in developed and developing countries has left policy makers uncertain on the exact policy to employ. In awe of this, after the discovery of diamonds and gold in South Africa, policy makers have attempted to improve the access, depth and efficiency of the finance sector to spur economic growth. However, South Africa has been subject to apartheid, low economic growth, global financial crises, international sanctions, unemployment and other challenges to the finance sector. In light of this, this study aims to empirically investigate the relationship between financial development and economic growth in South Africa. The study used the recently developed financial institutions index and financial markets index by the International Monetary Fund to represent bank-based and market-based financial development. This study utilises annual data over the period 1980 to 2014. The study applied the Autoregressive Disturbed Lag (ARDL) bounds testing, Vector Error Correction Model (VECM) Granger – Causality, Impulse Response Function (IRF) and Variance Decomposition to uncover the relationship between financial development and economic growth in South Africa. The ARDL was selected over the Johansen Cointegration because the variables can be I (1) or I(0) before carrying out the bounds testing. It is more suitable to a small sample size. It uses a reduced form equation, and it provides unbiased estimates of the long-run model. Lastly, it can be transformed into an error correction model. The VECM Granger-Causality was chosen because it represents the short-run and long-run causalities. After selection of the optimal lag, the ARDL bounds testing shows that economic growth, bank-based financial development, market-based financial development, savings and investment have a long-run relationship in South Africa. However, after estimation of the coefficients, financial development has a positive relationship with economic growth, but insignificant and only savings and investment were significant in determining long-run economic growth. The VECM granger-causality results show that financial development (bank and market), savings and investment granger cause economic growth in the long-run. While, economic growth, market-based financial development, savings and investment granger cause bank-based financial development in the long-run. Therefore, a feedback relationship exists between bank-based financial development and economic growth in the long-run. In the short-run, it was clear that bank-based financial development positively causes economic growth. The causality results show that a feedback relationship exists between bank-based financial development and economic growth in South Africa in the short-run as well. The IRF shows that a shock in economic growth negatively and positively affects bank based and market-based financial development respectively. A shock in bank-based financial development causes a positive effect on economic growth. Lastly, a shock in market-based financial development causes a positive effect on economic growth. Whilst, the variance decomposition shows that fluctuations in economic growth are increasingly explained by financial development (bank and market). While, fluctuations in bank-based financial development are increasingly explained by market-based financial development, savings and investment. The fluctuations in market-based financial development are increasingly caused by economic growth, savings and investment. It is recommended that policy makers utilise bank-based financial development for economic growth and reduced unemployment, to increase savings for long-run economic growth. Furthermore, challenges against market-based financial development should be reduced in order to create a positive relationship between investment and economic growth in the long run.

- Description: The financial sector plays a pivotal role in an economy of a country; hence the importance of financial development cannot be underestimated. Financial development is widely regarded as another conduit through which income inequality and poverty can be alleviated, however both theoretical and empirical literature does not reach consensus on the effect of financial development on income inequality and poverty. Against this background, the study empirically examines the effect of financial development on income inequality and poverty in selected Southern African Development Community (SADC) countries, employing the Generalised Method of Moments (GMM) technique for the period 1980 to 2011. Based on the inequalitydecreasing and Mckinnon Conduit effect, two models which link financial sector development and inequality and financial sector development and poverty were estimated using five different dimensions of financial development. Empirical results revealed that financial development overall does have an impact on income inequality and poverty in the selected SADC countries. An interesting observation from the empirical results is that the actual dimension of financial development plays a significant role in determining the relationship between financial development, income inequality and poverty in the SADC region. The impact of financial depth on poverty is not obvious in the study, depending on the variable used. On the relationship between financial system stability, income inequality and poverty, results reveal that a stable financial system is beneficial to the poor. Financial efficiency does not appear to have a significant role in reducing income inequality and poverty in the selected SADC countries. Overall, the findings from the study indicate that financial access or financial inclusion and financial stability is what reduces poverty instead of mere financial sector development at a broader level.

- Description: The financial sector plays a pivotal role in an economy of a country; hence the importance of financial development cannot be underestimated. Financial development is widely regarded as another conduit through which income inequality and poverty can be alleviated, however both theoretical and empirical literature does not reach consensus on the effect of financial development on income inequality and poverty. Against this background, the study empirically examines the effect of financial development on income inequality and poverty in selected Southern African Development Community (SADC) countries, employing the Generalised Method of Moments (GMM) technique for the period 1980 to 2011. Based on the inequalitydecreasing and Mckinnon Conduit effect, two models which link financial sector development and inequality and financial sector development and poverty were estimated using five different dimensions of financial development. Empirical results revealed that financial development overall does have an impact on income inequality and poverty in the selected SADC countries. An interesting observation from the empirical results is that the actual dimension of financial development plays a significant role in determining the relationship between financial development, income inequality and poverty in the SADC region. The impact of financial depth on poverty is not obvious in the study, depending on the variable used. On the relationship between financial system stability, income inequality and poverty, results reveal that a stable financial system is beneficial to the poor. Financial efficiency does not appear to have a significant role in reducing income inequality and poverty in the selected SADC countries. Overall, the findings from the study indicate that financial access or financial inclusion and financial stability is what reduces poverty instead of mere financial sector development at a broader level.

- Description: The relationship between financial inclusion and the growth of the economy is a topic of debate in the existing literature. Yet globally and at individual country level, policy makers have accepted financial inclusion as a developmental agenda. This study, therefore, empirically investigates the relationship between financial inclusion and economic growth in Ghana using quarterly time series data from 2005 to 2016. Employing the commonly used indicators, the ARDL bounds test with cointergration was applied to examine the short and the long run relationship between the variables. Furthermore, the Granger causality approach was also used to establish the direction between financial inclusion and economic growth in Ghana. The result of the findings confirmed mixed results and no clear cut relationship between the direction of causality between the indicators of financial inclusion and economic growth. The study concluded that whether financial inclusion positively or negatively impact economic growth rests on the indicators employed. The study therefore cautions in the choice of financial indicators as policy tools in designing and executing economic growth and development policies in Ghana.

- Description: This study provides an overview of hybridisation and methods to detect it in plants. This is documented in chapter 1. Another aim was to identify hybridisation between local and non-local species in the Proteaceae. This is covered in chapter 2. Finally the third aim was to develop a cheap and rapidly working method of detecting hybrids in this system. This is detailed in chapter 3. The model system for this research is the Van Stadens Wildflower Reserve. In 1984 the reserve manager introduced the non-local species, Protea susannae from Cape Agulhas. This represents a long-distance dispersal of over 600 km. This study is focused on looking at the impacts of the introduction of P. susannae on the local species P. eximia. I use genetic and morphological methods to detect hybrids. Hybridisation and the methods implemented to identify it are reviewed and discussed (Chapter 1). Morphological traits of the two species and direct sequencing of the nuclear ITS and chloroplast regions are compared (Chapter 2). This includes notes on the detection of hybrids and the potential for cryptic hybrids. I also focussed on testing of two rapid and low-cost techniques for detecting hybrids using Species Specific Primers (SSP’s) and High Resolution Melt (HRM). The Sanger sequencing method and ITS detected cryptic hybrids. The HRM was able to detect hybrids when comparing F1 putative hybrids to a ‘pure’ parent populations, but was not able to detect between a ‘pure’ parent population and F3 or F4 putative hybrids in the Van Stadens system. The SSP’s had the highest hybrid detection rate. Genetic methods, specifically the SSP’s were found to work well to detect hybrids in an environment where a hybrid swarm has taken place. The maps produced from this thesis will be useful for determining the distribution of hybrids in the reserve and for other similar hybrid systems. Long distance dispersal of Cape species may lead to the loss of genetic diversity or species as local and non-local hybridisation may occur, similar to the hybridisation between P. susannae and P. eximia in the Van Stadens Wild Flower Reserve. Genetic methods were shown to be superior to morphological hybrid detection (i.e. Sanger sequencing and SSP’s). The SSP approach tested here, which is dependent on the presence of fixed species specific SNP’s (Single Nucleotide Polymorphisms), could offer a rapid and effective method to explore hybridisation through space and time.

- Description: Education for Sustainable Development (ESD) in Higher Edu-cation has long been a subject of discussion (eg Sterling, 2010; Togo and Lotz-Sisitka, 2013; Baarth, Michelsen, Rieckmann, and Thomas, 2016), with an increasing number of arguments being put forward for transformative, and even transgressive (ie transgressing the taken for granted) learning in these contexts (Lotz-Sisitka, Wals, Kronlid, and McGarry, 2015). There is, however, as yet little theoretical or practical work that focuses on the border zone or the interface between Higher Education and Public Education, due perhaps to an overemphasis on internal change in Higher Education settings. Public Education brings sustainable development (SD) into everyday life focus (Von Poeck et al., 2012), as it is here that complex, ‘wicked’ problems (Rittel and Webber, 1973) are ex-perienced. Such problems defy easy resolution. In this chapter I address this gap in the ESD literature by drawing on three cases of public education praxis in the border zone between Higher Education and Public Education: 1) using mobile learn-ing tools to transform markets for small holder farmers; 2) build-ing social learning networks that cross boundaries between colleges, farmers, and universities; and 3) using arts-based creative practice methods for public action. I start with these case stories, exploring them theoretically in order to illuminate new possibilities for ESD praxis in the sections that follow.

- Description: A preliminary literature review indicated that little to no research exists on the Fintech phenomena in the South African context. The purpose of this study is to gain the perceptions of South African bankers on the Fintech phenomena and to develop a deeper understanding of the Fintech phenomena in the South African context. An empirical exploratory qualitative approach was employed and an interpretivism research paradigm was utilised. A detailed literature review was conducted into the Fintech phenomena as well as the financial services sector in South Africa. The use of purposive sampling was initiated, and the sample of the study consisted of five individuals who work for the largest South African banks. The data was gathered through in-depth structured interviews which consisted of ten predetermined research questions. Rich data was obtained which was then analysed through the use of content analysis and coding. This enabled the transcription of data and the extraction of codes which assisted in obtaining findings that answered the research question. Authenticity, rigor, trustworthiness and credibility criteria was applied from the onset and throughout the research study. The themes that emerged from the data analysis process were navigated so that findings could be reached by comparing the themes to previous literature. In conclusion, six themes emerged from the data analysis, namely; collaboration can create new markets and create market share, investing in Fintech to overcome legacy infrastructure by going digital, Fintech companies are more customer focused, balance regulation between protecting the industry and creating an innovative environment competition in future will be fiercer, competition is good for the performance of the financial services industry and the Fintech phenomena is positive for the banking industry. Certain findings and conclusions were drawn; regulations in South Africa do allow for innovation, regulation is not biased towards banks, banks innovate and collaborate through Fintech, Fintech is positive for the banking industry, South African banks are investing in preparation for Fintech, South African banks have limited budgets, there is no significant loss of market share for banks due to Fintech companies, market share can be gained by banks partnering with Fintech companies and the future of the financial services industry in South Africa.

- Description: Blue carbon is defined as the carbon sequestered and stored by coastal vegetated ecosystems including mangroves, seagrass and salt marsh. Research on blue carbon has rapidly escalated during the past decade following the 2009 United Nations Environment Program (UNEP) report, which highlighted the efficiency of these coastal habitats to act as carbon sinks. Mangrove forests in particular have been recognized for their significant role as carbon sinks and therefore have been prioritized in atmospheric carbon mitigation strategies. Despite global research efforts, there is still a notable knowledge gap on carbon storage potential of different mangrove tree species in underrepresented geographic regions. This study provides the first comprehensive assessment of blue carbon for a mangrove forest in a warm temperate estuary in South Africa. Carbon storage was quantified for Avicennia marina mangrove stands at the Nxaxo Estuary; using both elemental analysis and loss on ignition (LOI) techniques for sediment carbon pools and only elemental analysis for aboveground biomass (leaf litter, pneumatophores, wood).The environmental characteristics were the same at the five sites sampled and this was related to the estuary being well-mixed and permanently open to the Indian Ocean. Unexpectedly the carbon content was weakly correlated with that measured by elemental analysis. The cause of this is unknown and could potentially be an avenue for further investigation. The carbon content measured from elemental analysis was used in further calculations, as this method is reliable and meets global standards for comparisons. For the aboveground carbon pools, the pneumatophores (2.1 × 10-3 Mg C ha-1) stored significantly more carbon compared to the live trees (3.35 × 10-4 Mg C ha-1) and leaf litter (2.84 × 10-6 Mg C ha-1). The sediment carbon pool (228.05 Mg C ha-1) stored significantly more carbon than the aboveground carbon pools, which is in line with the findings of other studies from different regions. Sediment carbon storage was not related to mangrove tree population structure or sediment characteristics, such as moisture content and particle size. However, sediment carbon storage was highest at Site 2 which was located in a depositional area of the estuary. The total carbon storage is 1140.25 Mg C for the mangrove area of 9.5 the Nxaxo Estuary; this is considerably lower than what has been recorded for other regions. In South Africa, mangroves in warm--temperate regions occur at one of the southernmost limits globally and are restricted to occurring in sheltered estuaries due to the high--energy nature of the coastline. As a result, the growth and productivity of mangroves in these regions can be influenced by estuarine and climatic dynamics. Although total carbon storage was not variable between different sites at this estuary, this might not be the case on a regional scale as variability is expected to occur between estuaries within South Africa. Comparing the data collected from this study and others done globally, it is clear that the capacity for carbon storage by mangroves is variable. Therefore, regional scale blue carbon studies should be undertaken to provide estimates from direct quantification and allometric equation approaches. Carbon storage has been recognized as a valuable ecosystem service; therefore, going forward, accurate estimations of storage potential is essential, particularly for climate change mitigation and emission offset projects.

- Description: A functional hybrid of graphene quantum dots (GQDs) and cobalt pyrene-derivatized phthalocyanine (CoPc) used as a sensitive nanoprobe for the recognition of cyanide ion (CN−) is described in this work. The fluorescence of GQDs was quenched upon non-covalent (π-π stacking) hybrid formation with CoPc via a possible energy transfer pathway. However, in the presence of CN−, the interaction between GQDs and CoPc was perturbed, such that the fluorescence of GQDs initially quenched by CoPc was found to be efficiently recovered in the presence of CN−. Amongst the molecules and anions tested to ascertain their effects on the fluorescence behaviour of the hybrid, only CN− ion induced the tunable “off-on” restoration of the fluorescence of GQDs, which demonstrates the selectivity of the hybrid towards CN−. The restored fluorescence signals of the GQDs were linearly modulated by different concentrations of CN− and were used for the quantitative assay of CN− with high sensitivity coupled with rapid detection time. The detection was in the linear range of 1.0–50.0 nM with limits of detection (LOD) of 0.5 nM. The analysis of spiked samples for the recovery of CN− further demonstrated the applicability of the hybrid for the satisfactory detection of the target analyte.

- Description: The most policy document is the White Paper on Families, which aims to facilitate the mainstreaming of a family perspective into all government policy-making from the national to the municipal level and across multiple departments. The irony is that less than a third of South African families actually conform to the two cisgender heterosexual biological parent model that is favoured in family policy. South African research has shown that children of lesbian parents learn open-mindedness and to be comfortable with the family in which they live, and that men in same-sex relationships challenge gendered divisions of household tasks. Promoting the two-biological-parent family as the preferred family structure creates an impossible ideal for the majority of South Africans to live up to. Because such a family structure is strongly connected to class, it is out of reach for the majority of citizens, let alone those who live in queer relationships.

- Description: As the world continues to face widespread food insecurity, achieving food security for all at all times is increasingly complicated. In South Africa, social grants and the use of wild foods have been reported as some ways to improve household food insecurity and reduce poverty. The study examined if social grants and consumption of wild foods alleviate food insecurity in South Africa. Household surveys and focus group discussions were conducted along the rural-urban continuum in three South African towns situated along an agro-ecological gradient. We explored the differences in household food security indicators, mean monthly food expenditure and wealth index between households receiving social grants, households consuming wild foods, and those who did not. Households receiving social grants were more food insecure with lower mean monthly food expenditure and wealth index than those who did not.

- Description: As the world continues to face widespread food insecurity, achieving food security for all at all times is increasingly complicated. In South Africa, social grants and the use of wild foods have been reported as some ways to improve household food insecurity and reduce poverty. The study examined if social grants and consumption of wild foods alleviate food insecurity in South Africa. Household surveys and focus group discussions were conducted along the rural-urban continuum in three South African towns situated along an agro-ecological gradient. We explored the differences in household food security indicators, mean monthly food expenditure and wealth index between households receiving social grants, households consuming wild foods, and those who did not. Households receiving social grants were more food insecure with lower mean monthly food expenditure and wealth index than those who did not. Overall all towns, the use of wild foods improved household food security which was not true within towns where wild foods were mostly consumed by low income and more food insecure households. Social grants alone cannot eradicate food insecurity as the money is not enough to cater for all household needs whilst wild foods can potentially alleviate household food insecurity. As food prices continue to increase gradually and worsening household food insecurity, ways to shift ‘income circumstances’ of households and promote the use and consumption of wild foods which may increase dietary diversity and diversifying food access. Focus should be placed on capacity building, employment creation and promoting awareness on own food production which is one way to improve food security of poor households rather than depending on purchases from the grant money alone.

- Description: A well-nourished and healthy population is a central tenet of sustainable development. In South Africa, cultural beliefs and food taboos followed by some pregnant women influence their food consumption, which impacts the health of mothers and children during pregnancy and immediately afterwards. We documented food taboos and beliefs amongst pregnant isiXhosa women from five communities in the Kat River Valley, South Africa. A mixed-methods approach was used, which was comprised of questionnaire interviews with 224 women and nine focus group discussions with 94 participants.

- Description: In Africa, wetlands, such as shallow, ephemeral lakes provide ecosystem services, such as water purification, food supply, and flood control but are subject to dynamic flooding/drying cycles which vary in duration from years to decades. The stochastic nature of drying events subjects ephemeral lake fauna to persistent disturbance regimes, therefore understanding how biota respond to flooding and drying events is essential for their conservation and management. Primary production sources supporting consumer biomass in the shallow ephemeral Lake Liambezi (upper Zambezi Ecoregion), were investigated using stable isotope analysis, mixing models and stomach content analysis to investigate the following hypotheses: (1) algal primary production supports a higher consumer biomass than aquatic macrophytes; (2) the lake food chain is short, because the majority of fish fauna are detritivorous/herbivorous cichlids that are consumed by top predators; (3) fish community trophic structure will be similar between years; and (4) with short food chains and stochastic resource availability, there will be substantial competition for food among fish species.

- Description: The sky-averaged (global) spectrum of the redshifted 21-cm line promises to be a direct probe of the Dark Ages, the period before the first luminous sources formed and the Epoch of Reionization during which these sources produced enough ionizing photons to ionize the neutral intergalactic medium. However, observations of this signal are contaminated by both astrophysical foregrounds which are orders of magnitude brighter than the cosmological signal and by non-astrophysical and non-ideal instrumental effects. It is therefore crucial to understand all these data components and their impacts on the cosmological signal, for successful signal extraction. In this view, we investigated the impact that small scale spatial structures of diffuse Galactic foreground has on the foreground spectrum as observed by a global 21-cm observation. We simulated two different sets of observations using a realistic dipole beam model of two synchotron foreground templates that differ from each other in the small scale structure: the original 408 MHz all-sky map by Haslam et al. (1982) and a version where the calibration was improved to remove artifcats and point sources (Remazeilles et al., 2015). We generated simulated foreground spectra and modeled them using a polynomial expansion in frequency. We found that the different foreground templates have a modest impact on the simulated spectra, generate differences up to 2% in the root mean square of residual spectra after the log-polynomial best fit was subtracted out.

- Description: Nigeria has the largest population in Africa and with approximately 160 million people. Nigeria has one of the largest populations of poor people in the world. Over the years, the rate of maternal and child mortality reduction in Nigeria has been slow and this is largely due to bad infrastructure, low quality of education and poor health sector. This is largely due to government bureaucracy, problems within the aid administration process and its influence on developmental issues. The Millennium Development Goals (MDGs) were created for countries to address human developmental issues within different countries around the world. The countries had to meet MDGs by 2015. Nigeria was not able to meet many of the set targets and had made only few improvements within the health department. This is largely due to government bureaucracy and the slow pace that is maintained during the formulation and implementation of governmental policies and programs. This study seeks to explore various issues that are identified in the attainment of MDGs 4 and 5: MDGs 4 with target 5 - 2/3 reductions in under than five mortality rates and MDG 5 with target 6 - ¾ reductions in the maternal mortality rate. This study will assess the efforts made by local and international organizations during the implementation of MDGs 4 and 5. This study will identify the impact of foreign aid on the health sector, with an intervention on the maternal and child mortality ratio, key international donors in the maternal and child sector. Document analysis is been adopted as the methodological approach for this research. These analysis focuses on documents such as publications, reports, policy papers and academic literature. One of the key findings in this study is that - lack of good policies of health services is a major barrier to the improvement in maternal and child mortality in Nigeria.

- Description: This chapter addresses a research problem identified in the vocational agricultural learning system where there was a gap in vocational education and training knowledge flow from research institutions to knowledge users. The chapter develops a theoretical framework for dealing with the problem of ‘knowledge flow’ in vocational education and training settings. The problem emerges around the uptake and use of relevant research-based knowledge resources on rainwater harvesting and conservation practices for agricultural education and training focused on small-scale farmers and household food producers in South Africa. These resources, despite their con-temporary relevance, were not being used in agricultural col-leges or in the related agricultural learning support system. Drawing on a social ecosystemic approach to knowledge flow and mediation, the chapter surfaces five iterative mediation processes developed via a generative, formative interventionist research process over a five year period (Lotz-Sisitka et al. 2016; Pesanayi, 2019; cf. Chapter 8) that facilitated the development of a regional learning network which enabled vertical facilitatory processes and horizontal connectivities that impact-ed on farmers’ food production system, as well as the agricultural learning system. We illuminate key features of these as important for supporting knowledge flow within a regional social ecosystemic framework for skills development.
