- Description: Twenty-three (23) years have elapsed since South Africa parted ways with the apartheid system. Nevertheless, poverty, inequality, and unemployment pose the greatest threat to human dignity and social cohesion. Section 27 (1) (c) of the Constitution obligates the state to develop a comprehensive social security system. It affirms the universal right to access social security, including appropriate social assistance for those unable to support themselves and their dependants. It orders the state to take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of these rights. The underlying normative commitment of social security is the improvement of the quality of life of the population by promoting economic or material equality. The study provides a general overview of the system of Social Security in South Africa as a Member State of the ILO. In particular, the study underscores that South Africa has not ratified ILO Convention No. 102 Social Security (Minimum Standards) Convention, 1952 and other Conventions relevant to Social Security. The study examines the need to ratify the said Convention in order to receive extensive coverage that would, among other benefits receive guarantees for a well-established system and thereby potentially reduce poverty. The Constitution is the supreme law of the country, it clearly stipulates that when interpreting, and applying the statutes international law must be considered. The study illuminates the significant benefits the country would receive from ratifying Convention No. 102.

- Description: Since the principal source of retirement income is savings, the significance of projecting desirable savings behaviour during the pre-retirement phase can never be overestimated. Notably, the majority of low-income consumers in South Africa are not sufficiently prepared for retirement. This provides fertile ground for clarifying the importance of positive long-term savings behaviour. This study aimed to present a composite view by delineating both rational and irrational markers of financial efficacy and self-reported savings behaviour, whilst simultaneously discussing how such determinants can be predisposed towards increasing an individual’s retirement savings rate. Procedural techniques in the form of multiple regression analysis quantified the impact of financial risk tolerance, perceived income adequacy and social norms influence on individuals’ efficacy towards long-term savings behaviour. The findings of this study have practical implications for financial advisors, on how increased financial needs awareness amongst low-income consumers regarding future retirement life may be generated. Furthermore, this paper contributes towards the development of thriving communities by proffering knowledge on enhancing resource utilisation in lieu of increasing long-term financial security among low-income households.

- Description: The thesis engages with the photographic collection of Dr Pauline Ingle, an amateur photographer who lived and worked in the former Transkei as a medical doctor from 1948-1976. As a visual history project situated within critical visual studies, the thesis is concerned to attend to the disciplinary optics that have conditioned seeing and constituted genres; but also the ways in which these genres have constituted subjects and corralled them into positions commensurate with the spatialised demarcations of the rural and the urban, and the attendant associations of tradition and modernity. The thesis begins by exploring the biography of Pauline Ingle and tracks the movement of the photographs from a private collection into the public realm and its constitution as an archive. The thesis then moves into a discussion of the key determinants of the ethnographic genre and its entwinement with the discipline of anthropology, as a foundation against which to investigate the limits of reading her images within this genre and the disruptions that are discernible through an aesthetics of proximity and forms of image-making that do not control the visual field. Through a theorisation that proposes the image as an act, various readings are brought to bear on the images through the lens of the social and political. Mobilising the concepts of social acts and acts of citizenship, allows for a reading that breaks with the disciplinary conditioning that has fixed subject positions into ‘the native subject’ and the ‘liberal subject’ and calls into question the construction of the human. By proposing the subject as migrant, is to signal that the question of the human/subject is more complex and convoluted than previously thought.

- Description: In this paper, we present the design and implementation of a NPU-CPU heterogeneous network monitoring application. This application allows for both filtering and monitoring operations to be performed on network traffic based on country of origin or destination of IP traffic in real-time at wire speeds up to 1 Gbit/s. This is achievable by distributing the application components to the relevant candidate architectures, leveraging the strengths of each. Communication between architectures is handled at runtime by a low latency synchronous message passing library. Testing of the implemented application indicates that the system can perform geolocation lookups on network traffic in real-time without impacting network throughput.

- Description: Background: The initiation of ante-natal care booking is universally recommended in the first trimester of pregnancy. While working in the Oliver Reginald Tambo district in the Eastern Cape Department of Health, the researcher noticed that late booking was the norm in all sub-districts, especially in the King Sabata Dalindyebo (KSD) sub-district, resulting in impaired antenatal care and an increased potential for adverse outcomes such as maternal mortalities. Purpose of the study: The purpose of the study was to explore and describe the reasons for late booking for antenatal care by pregnant women in the KSD sub-district. Objectives: The objective of the study was to determine reasons why women were booking late for antenatal in KSD sub district. Methods: Thirteen in-depth, unstructured interviews were conducted with late bookers (i.e., those who sought antenatal care (ANC) after twenty weeks of pregnancy) between July and August 2015. The interviews were recorded and, subsequently, transcribed by a reputable linguist from Walter Sisulu University (WSU) and analysed using Creswell’s thematic analysis model. Findings: The average gestational age of booking was 22 weeks (ranging from 22 to 28 weeks). Most women were teenagers and young unmarried women, most of whom were still attending school. All were unemployed. Most had experienced previous pregnancies. All these women delayed attending clinic early due to their ignorance of the exact gestational period for one to start the clinic. Although most of the women did not have direct reasons, the bulk of their reasons for delays were linked to long distances being travelled, leading to the payment of expensive taxi fees. This may also be attributed to cultural factors that seem to promote a veil of secrecy regarding pregnancy, the desire for visual evidence of pregnancy first and the practice of married women having to care for sick relatives. Conclusion: Poor access to clinics is a fundamental systemic failure and a major contributor and one of the reasons why women delayed in attending antenatal care clinics. Low socio economic status and cultural beliefs, coupled with long distance and expensive taxi fare, are other reasons for late booking.

- Description: Records Management is playing a crucial role in government institutions, municipalities. This study sought to explore records management practices in for accountability in the Pixely ka Seme District in the Northern Cape Province in South Africa. The study sought to investigate whether the current records management practices upkeep or demoralize accountability and ultimate service delivery in the local municipalities. These are the objectives that were intended to be accomplished by the study: To find out the role of the provincial archives in the records management practices in Pixely ka Seme in the Northern Cape Province; To determine the extent to which records management practices in the Pixely ka Seme District in the Northern Cape Province comply with the legal and regulatory requirements; and To assess the impact records management practices on service delivery in the Pixely ka Seme District in the Northern Cape Province. Geographical Area; The district is comprised of eight local municipalities: Ubuntu, Umsobomvu, Emthanjeni, Kareeberg, Renosterberg, Thembelihle, Siyathemba and Siyancuma. Its main town is De Aar. Traffic flows through the region, linking the major industrial areas of the country. The area has a low rainfall, while the largest river in South Africa flows through it. Two of the major dams in South Africa, the Vanderkloof and Gariep Dams, are situated on the borders of the district municipality. Main Economic Sectors; Finance and business services (22.5percent), manufacturing (17.4percent), trade and accommodation (15.4percent), government services (12.9percent), transport and communication (11.3percent), mining (6.8percent), community and social services (5.6percent), construction (3.3percent), agriculture (2.7percent) Mixed methods were used for the investigation. Questionnaires and in depth interviews were used to collect data. Purposive sampling method was used to identify interview participants and adopted open ended questions to collect all necessary information by a questionnaire. The total population of the study was the Pixely ka Seme District employees in the Northern Cape Province. The Records Management Officials from eight local municipalities. The study sampled 18 participants but ended completing the investigation on 9 participants purposively. Total of Nine; 5 (56percent) of the participants were females while 4 (44percent) were males. The process was made possible through the use of purposive sampling to have the targeted respondents of the study. The study was enclosed within the theoretical frame of the “Life Cycle of a record” model and “Continuum model” to outline the whole process of record keeping discipline. The study discovered that records management negatively affected timely, effective and efficient accountability and in terms of audit results and service delivery. The results of the study revealed the dominance of the females in the records management practices in the Pixely ka Seme District. This finding was used was to analyze the impact of gender equality in the records management practices in the district. In this study, there is of a high number of females as compared to males and the study concluded that females led the records management structure in the Pixely Ka Seme District. Furthermore, the age range in this study proved to be one of the major factors that led to poor records management practice in the District. In addition, that qualification in relation to records management is the major hindrance in effective records management in the in the Pixely Ka Seme District in Northern Cape Province. Hereinafter, The Provincial Archives is not involved at all in the records management practices in the Northern Cape Province in the Pixely Ka Seme District. A large number of the municipalities do not have records management policies in place for the practice of proper records management. It is evident that records management compliance in compromised in this regard. A significant large number of the municipalities function without a legislative provision in terms of its record keeping. The study recommended that municipalities should now employ more and qualified records managers to rescue institutional records and the image of the organization. South African Local Government Association Records Management Forum (SALGA) as a municipal advocate must emphasize and command that municipalities must employ records managers at a managerial level to improve records section and professionalism in the field of records.

- Description: The thermoset market is dominated with petroleum-based products. The rising concerns on depletion of non-renewable resources and climate change has motivated researches and industries to find green alternatives for petroleum based materials. The thermoset polymer poly-furfuryl alcohol (PFA) displays good chemical, viscoelastic and moisture stability properties and importantly is bio-based, however, the cured PFA resin is very brittle. The approach of incorporating different types of particulate fillers into the PFA matrix and reinforcing the PFA matrix with flax fabric was used to address the brittleness issue associated with PFA. In the first study, flax fabric was treated with a diammonium phosphate based flame-retardant to reduce the flammability. Compression moulding was used to produce PFA biocomposites and PFA laminates. The effect of the flame-retardant was investigated using Scanning electron microscope (SEM), x-ray diffraction (XRD), fourier transform infrared (FTIR), and cone calorimeter, flexural and tensile tests. The flame-retardant treatment significantly improved the flammability properties, however, decreased the flexural and tensile properties. In the second study, 10 different fillers were selected, these being; ZnO, Clay, montmorillonite (MMT), Rubber, Chitin, Starch, CaCO3, Chitosan, Lignin and TiO2. These fillers were incorporated into the PFA resin at 2% and 5% concentration and reinforced with untreated (UT) flax fabric and flame-retardant (FR) treated flax fabric. Flexural, tensile and izod impact tests were performed on the cured laminates. Thermogravimetric analysis (TGA), SEM and micro x-ray computed tomography scan (CT scan) analysis was performed on selected samples. The inclusion of MMT and Rubber significantly increased the strength and the stiffness of the PFA/UT-Flax laminate while Clay and ZnO reduced the brittleness of the PFA/UT-Flax laminate. FR laminates generally exhibited poor mechanical properties regardless of the type of filler. This was the result of FR damaging the flax fibres during the compression moulding process and hindered the interaction between the PFA matrix and flax fabric. TGA results showed that FR treatment increased the thermal stability of the PFA laminate. SEM and CT scan analysis illustrated the large amount of voids between fabric layers, especially for UT-Flax laminates. The fillers MMT, Rubber and ZnO had a positive effect on the mechanical properties of UT-Flax laminates and therefore were used in the third study. A Box Behnken design of experiment was developed in which the concentration of MMT, Rubber and ZnO was varied between 0 – 5%. Multiple linear regression was used to model the mechanical properties of the PFA/UT-Flax laminates based on a full quadratic model. An optimized filler combination was determined with Solver ®. The experimental results of the optimised PFA/UT-Flax laminate were compared to the values predicted with the statistical model.

- Description: Smallholder farmers have been growing food in their communities, but some are still food insecure. Therefore, appropriate food systems are very important for smallholder farmers’ self-reliance as well as food and nutrition security. The study focuses only on community and regional maize food systems for rural households. The main aim of this study was to investigate the regional and community food systems for smallholder maize farmers in Mqanduli. The objectives of the study were to profile smallholder maize farmers, describing the existing maize food systems and patterns in Mqanduli and also to determine factors that influence farmers’ participation in local or regional markets. Availability or convenient sampling and random sampling techniques were used to collect primary data from smallholder maize farmers. Descriptive statistics was used to profile smallholder farmers, as well as, in describing the existing maize food systems at Mqanduli. The binary logistic regression model was used to analyse the variables that had influenced the smallholder famers’ participation in markets. Descriptive results revealed that, smallholder maize farmers in Mqanduli are characterised by high participation in both local and regional markets. Moreover, they utilized both community and regional food systems. Logistic regression results indicated that, out of 11 variables included in the analysis as factors influencing farmers’ participation, 6 of them (age, level of education, market information, distance, access to credit and extension visit) were found to be significant and 5 (gender, amount of land, transport availability etc) were not significant. However, access to credit and distance were found to be the most significant variables, showing a positive relationship to smallholder maize producer`s market participation. Therefore, it was recommended that, there must be more investment in research by government and policy makers when it comes to food systems especially in rural areas, to enhance smallholders’ livelihood. More access to credit is also needed by farmers in order to be able to market their produces.

- Description: Smallholder farmers have been growing food in their communities, but some are still food insecure. Therefore, appropriate food systems are very important for smallholder farmers’ self-reliance as well as food and nutrition security. The study focuses only on community and regional maize food systems for rural households. The main aim of this study was to investigate the regional and community food systems for smallholder maize farmers in Mqanduli. The objectives of the study were to profile smallholder maize farmers, describing the existing maize food systems and patterns in Mqanduli and also to determine factors that influence farmers’ participation in local or regional markets. Availability or convenient sampling and random sampling techniques were used to collect primary data from smallholder maize farmers. Descriptive statistics was used to profile smallholder farmers, as well as, in describing the existing maize food systems at Mqanduli. The binary logistic regression model was used to analyse the variables that had influenced the smallholder famers’ participation in markets. Descriptive results revealed that, smallholder maize farmers in Mqanduli are characterised by high participation in both local and regional markets. Moreover, they utilized both community and regional food systems.

- Description: This thesis investigates how regional value chains (RVCs) can be used to further development integration in the Southern African Development Community (SADC) region with a focus on the pharmaceutical manufacturing industry. The study is motivated by the apparent lack of attention given to the development of the pharmaceutical manufacturing industry in Southern Africa, the region’s high disease burden and the identification of the industry as economically and socially important by the SADC (2015) Industrialisation Strategy and Roadmap and the Department of Trade and Industry (DTI) (2017a) Industrial Policy Action Plan (IPAP). At the same time, South Africa and other countries in the region are exploring alternative approaches to regional integration, given the failure or stagnation of numerous formal integration arrangements throughout Africa, which have often lead to polarised rather than balanced development. This thesis argues that the development of RVCs within SADC may be an effective tool for development integration in the region, particularly in sectors such as pharmaceuticals. The study employs a value chain framework for the analysis and discusses development integration options, drawing on the East Asian experience with RVCs and on case studies involving India in the case of the pharmaceutical industry. It provides a sector profile of the industry in South Africa, due to its dominant status in the region, and also of Zimbabwe, due to that country’s potential to become a pharmaceutical industry leader in the region once again. The thesis first explores the important theoretical aspects underlying value chain analysis, namely governance and upgrading, while also outlining the rise of global value chains (GVCs). It analyses the complex relationships between RVCs and GVCs, and RVCs and regional integration. From this it concludes that RVCs are a stepping stone to participation in GVCs and that RVCs should be promoted within a development integration framework through strong regional cooperation. Value chain analysis is applied to the entire pharmaceutical manufacturing industry with a focus on SADC. The thesis examines how the sector is evolving with manufacturing multinational corporations (MNCs) outsourcing production and setting up centres of excellence in regional production hubs. The study argues that with the application of recommended policies, RVCs in sectors such as pharmaceutical manufacturing may provide a tool for achieving balanced development in the region. However, the study also finds that the pharmaceutical industry in SADC lags a long way behind the rest of the world and that many countries and firms will need to begin at the bottom of the value chain, with formulation, in order to contribute to the development of RVCs. The thesis concludes with recommendations on what policies are needed to foster the growth and development of pharmaceutical RVCs in the SADC region. These include strengthening public procurement, providing incentives for investment into the industry, incremental production and incremental export volumes, as well as certainty and predictability around the regulatory and business environment. Further, policy should aim to construct synergies and linkages on the ground between health systems and industrial developments; regulate service links important to pharmaceutical manufacturing; develop a coherent regional policy agenda; remove unnecessary non-tariff barriers to trade in the region and, in line with development integration, implement trade policy along with trade infrastructure that is efficient and includes airports, rail, roads and ports, as well as effective access to the internet.

- Description: South Africa has in the recent past seen employees embarking in strike action, even in sectors designated as essential services. The impact adversely affected inter alia economic growth, investor confidence, international credit ratings and the high rate of unemployment. The Labour Relations Act 66 of 1995 from its inception on 11 November 1996, and as amended, in 2002 and in 2015, has brought about some minor changes to the model aimed at regulating essential services, maintenance services and minimum services agreements. This research is aimed at investigating; whether essential services, maintenance services and minimum services agreements are designed to unjustifiably limit the right to strike or not. The Constitution1 and the Labour Relations Act, 19952 encourages parties in employment relationship to engage in collective bargaining. Mechanisms such as a no duty to bargain envisaged within the current LRA regulatory framework, appears to be undermining the significance of ensuring that parties engaged within services designated as essential and maintenance services exercise their fundamental right to strike and to bargain collectively. The Essential Services Committee when dispensing with its statutory functions may be unjustifiably limiting the right to strike for employees engaged in essential and maintenance services. Some employers may be to some degree reluctant to trigger maintenance services provisions as the LRA appears to be adopting a voluntarism principle when regulating collective bargaining, as the Act is encouraging employers to deal with the provision of maintenance services within collective agreements. An introduction of a judiciable enforceable duty to bargain collectively in services designated as essential and maintenance services may compel employers to conclude minimum services agreements. The extremely low number of services designated as maintenance services is a worrying reality and the solution is urgently required.

- Description: The extracellular matrix (ECM) serves as a scaffold for cells within tissues and is composed of an intricate network of glycoproteins, growth factors and matricellular proteins which cooperatively function in cell processes such as migration, adhesion and wound healing. ECM morphology is constantly undergoing remodelling (synthesis, assembly and degradation) during normal cell processes and when deregulated may contribute to disease. Heat shock proteins (Hsps) are involved in regulating processes that determine the assembly and degradation of the ECM at multiple levels, in both normal and diseased states. These roles include mediating the activation of ECM-degrading enzymes, maintaining matrix stability and clearing aggregated/misfolded proteins. Hsp may serve as chaperones and receptors or have cytokine-like functions. In this chapter, we review how Hsp90, Hsp70, Hsp40 and a number of ER resident chaperones contribute to ECM regulation. The role of the non-Hsp chaperones, SPARC and clusterin in the ECM is also discussed.

- Description: Protected areas are increasingly expected to justify their existence in terms of their importance to society. However, this importance, and the complex ways in which people relate to protected areas, cannot be captured by instrumental and intrinsic value framings alone. Rather, our understanding of the role of protected areas in society needs to take account of people’s relational values about nature. Here we review the literature on values associated with human-nature connection and related concepts to highlight which approaches are currently being used to understand expressions of relational values in empirical protected area research. Our results highlights seven ‘application domains’ for relational values research, highlighting expressions of relational values, and the stakeholder focus of each. Place-focused and psychological theories were most common across these domains. This work represents a first step in developing the foundations of a relational value research agenda in protected areas.

- Description: Background: Alcohol use prevalence has been found to be higher than 50 percent at some universities in South Africa. It is against this background that this study aimed to establish the relationship between alcohol use, knowledge of alcohol-attributable health conditions and biographical characteristics. Literature review: The study was based on a review of literature on prevalence and patterns of alcohol use among university students, knowledge of alcohol-attributable chronic diseases, foetal alcohol syndrome, sexual and reproductive health and alcohol use measurement. Methodology: Data were collected from 213 undergraduate students enrolled for the Statistics service courses on two campuses of the same university. The Mann-Whitney normal approximation and the Kruskal-Wallis tests were used to compare health knowledge across levels of alcohol use and biographical characteristics. The chi-squared test and multiple logistic regression analysis were used to determine the significance and patterns of associations between alcohol use and health knowledge and biographical characteristics. Results: The prevalence rates of alcohol use and risky alcohol use were found to be 58.2 percent and 42.7 percent, respectively. The mean health knowledge was 42.9 percent, which, is rather low. Males [OR=0.3; 95 percentCI (0.18; 0.68)], returning students [OR=0.5; 95 percentCI (0.25; 0.94)] and those with employed fathers [OR=2.3; 95 percentCI (1.19; 4.47)] were found to be at a higher risk of alcohol use. Health knowledge was significantly higher among alcohol users (Z=-2.7; p=0.0074) and those whose fathers had a post matric education (𝜒2=6.4; p=0.0410) and/or employment (Z=-2.7; p=0.0064). Conclusion: While prevalence rates of alcohol use and risky alcohol were high, health knowledge was disappointingly low. This suggests need for interventions designed to minimise alcohol use while at the same time increasing health knowledge.

More specifically, two moments in time are captured and analysed, namely, Mandela’s release from prison together with the lead up to the first democratic South African elections in 1994; and his passing in 2013. This analysis includes the work of poets such as Bongani Sitole, Maya Angelou, Raphael d’Abdon and Thabo Mbeki. The mechanics of translation and the interrelatedness of orality and literacy are explored. The poetic memory contained in this article presents us with an approximation towards the collage of collective memory in a country where economics, politics, and society still present multiple challenges, and where political power often challenges the true collective memory.

- Description: Energy is a critical component for the economic growth and development of developing countries. In particular Zambia’s economy requires energy in order to contribute to the reduction of poverty and inequalities in income and gender. Zambia faces an energy deficit which is compounded by lack of adequate financing and low electricity tariffs. The current energy deficit can challenge the achievement of such goals by Zambia. The aim of this research was to explore the impact of renewable energy project financing on Zambia’s economic growth and development. The mixed research methods through the use of questionnaires and interviews were used in achieving the research aim and objectives. In addition primary and secondary data were used as data sources for this research study. The current energy deficit in Zambia has negatively affected all the sectors in Zambia. In order to address the energy deficit, investments in the energy sector particularly through the use of project finance are required as such investments have the potential to improve energy generation, distribution and supply. Zambia has many sources of renewable energy such as solar, wind, hydro, biomass and geothermal making renewable energy project financing as the potential energy source to plug the energy deficit. By extension investments in renewable energy provide an opportunity for investors to expand their businesses and recoup their investments with high returns. Thus many sectors such as health, education, agriculture and service among others would benefit from the increased energy supply thereby improving their operations and spurring economic activities. Furthermore, renewable energy would improve access to energy in both urban and rural areas where electrification rates are as low as 25% and 3% respectively. Despite such positive impacts of renewable energy project the following account for the negative impacts: Externalisation of profits by investors; and, Over dependence on hydro-power. As energy is critical for economic growth and development of Zambia the major recommendations include the following: Seizing Project Finance Opportunities – with the abundance renewable energy resources such as solar, wind, geothermal and biomass, project finance in the form of debt and equity can be utilised to develop and implement renewable energy projects in order to improve energy generation, supply and distribution; Accelerating Renewable Energy Projects - Given the positive impacts of renewable energy project financing on economic growth and development in Zambia, renewable energy projects should be accelerated to result in increased economic growth and development; Removal of Red Tape - The government should reduce the red tape to ensure attraction of investments and implementation of renewable energy projects. Removal of red tape can accelerate investments and implementation of renewable energy projects as was the case in Kenya; Raising Awareness on Renewable Energy Benefits - Making investors and citizens aware (through investment forums and government websites) about the benefits of renewable energy would attract investors but would also allow local people to participate in the implementation of renewable energy projects. Further research – As this research involved organisations and participants in Lusaka province further research involving more participants and organisations outside Lusaka province is required to improve the research results. In addition further research is required to be conducted during reduced levels of energy deficits to improve research results. In this regard the recommendations are aimed at improving energy generation, distribution and supply so as to contribute to the economic growth and development of Zambia.

- Description: Assessing species phenology provides useful understanding about their autecology, to contribute to management strategies. We monitored reproductive phenology of Mimusops andongensis and Mimusops kummel, and its relationship with climate, tree diameter and canopy position. We sampled trees in six diameter classes and noted their canopy position. For both species flowering began in the dry season through to the rainy season, but peaked in the dry season, whilst fruiting occurred in the rainy season and peaked during the most humid period. Flowering was positively correlated with temperature. Conversely, fruiting was negatively correlated with temperature and positively with rainfall, only in the Guineo-Sudanian zone. For M. andongensis, flowering and fruiting prevalences were positively linked to stem diameter, while only flowering was significantly related to canopy position. For M. kummel, the relationship with stem diameter was significant for flowering prevalence only and in the Guineo-Sudanian zone. Results suggest that phylogenetic membership is an important factor restricting Mimusops species phenology. Flowering and fruiting of both species are influenced by climate, and consequently climate change might shift their phenological patterns. Long-term investigations, considering flowering and fruiting abortion, will help to better understand the species phenology and perhaps predict demographic dynamics.

- Description: Legislative and policy prescripts determine how the South Africa government plans for and reports on the services meant to benefit the citizens of the country. Legislators and the public should rely on an annual audits of financial and performance information to gauge the success of these services. the framework governing performance planning and reporting outlines a number of public sector reform objectives intended to enhance achievement of government's desired outcomes. Improvements in audit status over the past number of years have, however, been undermined by increasingly frequent service delivery protests, suggesting that the intentions of the framework are not realised.

- Description: This small-scale case study explores the potential for synergy between music and mathematics learning in early childhood education whereby music can be used to help enhance children’s mathematical proficiency. Informal observations of the young learners participating in an Early Number Fun programme initiated by the South African Numeracy Chair Project suggested that many children struggled to exercise executive functioning and self-regulated skills, and struggled also with fluency in basic numeracy concepts such as understanding pattern. This case study was set up to investigate the effect of the development and implementation of a programme in which African music and mathematics learning, (particularly in relation to pattern and sequencing) were blended. The study’s core aim was to contribute to strengthening learners’ executive function and self-regulated learning competencies, both of which are important to learners’ developing agency over their own learning. An Action-Research-embedded-in-Design-Research approach was employed. This allowed an iterative process in developing a new mode of learning through blending music and mathematics. The theory of enactivism provided a theoretical framework to the study. The basic assumptions of an enactive perspective are shared understanding and joint action through engagement (as exemplified through group interaction between learner and teacher, and learning through action). The programme was developed and implemented with ongoing refinements in two Grade R classrooms. Data collected through observation, interviewing, document analysis and the keeping of a reflective research journal, are qualitative in nature. Analysis of the data indicate that the use of African block notation, as a rhythmic medium was well within reach of the participating children, such that at the end of each 16 session intervention programme, learners at both research sites demonstrated their capacity to: • Focus their attention on one activity while a different activity was taking place alongside them. • Watch, listen and only then act. • Practise their numbers through play: to count out and to write up to 16 and beyond. • Notate, read and interpret rhythmic patterns through block notation and instrumentation. The findings suggest the intervention programme could be continued over a longer period for maximum benefit, possibly through following Grade R learners through to Grade 1. The findings further suggest that fun with rhythmic, number-based patterning can assist learners’ development of executive function and self-regulated learning skills.

- Description: The International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (IBRD) now the World Bank, were created in the mid-1940s. The IMF was tasked to manage the post-war international monetary system, while the World Bank’s role during its early years was to provide development finance to war-torn Europe. These institutions reformed some of their roles to make them relevant to the globalising world over the years and also responded to several post-war crises. Since these two institutions carry out their roles in a globalising world, this study has revealed that globalisation has different interpretations as many researchers refer to the economic and non-economic explanations of its meaning. Globalisation is also a historical process as it traces back several years ago. Since approximately the mid-2000s, the global economy experienced two economic crises, namely the US sub-prime financial crisis that later became the Great Recession and the Euro sovereign crisis. The two economic crises spread to other countries globally that were interconnected into the global economy regarding international trade, investment and banking. These two crisis events required responses from the IMF and the World Bank. The two institutions displayed a variety of strengths and weaknesses in dealing with the recession and the Euro crisis. The lending of both these institutions has been their strength as they have managed to expand their lending capacity during the two crisis periods examined. The IMF’s crisis intervention time frames have also been its strength, as the speed in which it has approved financial assistance requests has been within reasonable time frames. The IMF’s new lending instruments have been its weakness, as the success of these instruments has not been fully tested so far. This is because of the little use of the IMF’s new lending instruments. The IMF’s crisis prevention efforts through the use of its surveillance tools have also been its flaw. This is based on the fact that it has failed to prevent the US financial crisis (later the Great Recession) and the Euro sovereign crisis. Overall, this study found that these institutions played a significant role in responding to the Great Recession and Euro sovereign crisis as their strengths outweigh their weaknesses. However, the weaknesses of the IMF confirm that it needs to reform its role and learn from its flaws in the future.

- Description: Urban green infrastructure and its ecosystem services are often conceptualised in terms of a predominantly western perspective of cities and their wider social, economic and environmental challenges. However, the benefits which are derived from urban ecosystems are equally – if not more – important in the cities of the developing world. Cities in sub-Saharan Africa are well known to be facing severe pressures. Nevertheless, despite the challenges of rapid population change, high levels of poverty and seemingly chaotic urban development processes, there are also tremendous opportunities. Realising the opportunities around urban green infrastructure and its benefits requires harnessing the inherent local knowledge and community innovation associated with a multitude of inter-connected urban social-ecological systems. Such systems are a powerful driving force shaping urban realities. Associated planning regimes are frequently lambasted as being either absent, weakly enforced, corrupt or wholly inappropriate. Much of this criticism is justified. However, it must also be recognised that decision-makers are frequently working in contexts which lack the scientific foundations through which their decision-making might be made more effective and complementary to bottom-up initiatives. The paucity of research into urban ecosystems in sub-Saharan Africa and the lack of development of context-specific conceptual, theoretical and empirical foundations is a problem which must be addressed. Drawing on papers from a Special Issue centred on urban green infrastructure and urban ecosystem services in sub-Saharan Africa, we consider what concepts and frameworks are in use and what needs to be considered when framing future research. We also synthesise key messages from the Special Issue and draw together themes to help create a new research agenda for the international research community.
