- Description: There has been a rapid increase in atmospheric CO2 concentration, from pre-industrial values of 280 ppm to more than 400 ppm currently, and this is expected to more than double by the end of the 21st century. Studies have shown that plants grown above 600 ppm tend to have an increased growth rate and invest more in carbon-based defences. This has important implications for the management of invasive alien plants, especially for the field of biological control which is mostly dependent on herbivorous insects. This is because insects reared on such plants have been shown to have reduced overall fitness. Nevertheless, most of the studies on potential changes in plant-insect interactions under elevated CO2 are based on agricultural systems, with only a limited number of these types of studies conducted on alien invasive weeds. However, climate change and invasive species are two of the most prevalent features of global environmental change. Therefore, this also warrants active research and experimental studies to better understand how these systems will be affected by future climates. Thus, the aim of this study was to investigate the effects of elevated atmospheric CO2 on the biological control of four invasive aquatic weeds (Azolla filiculoides, Salvinia molesta, Pistia stratiotes, and Myriophyllum aquaticum). These species are a threat to natural resources in South Africa but are currently under successful control by their biological control agents (Stenopelmus rufinasus, Cyrtobagous salviniae, Neohydronomus affinis, and Lysathia n. sp.). To achieve this, the selected plant species were grown in a three-factor experimental design in winter (CO2 X nutrients X herbivory), and another two-factorial design in summer (CO2 X herbivory). Atmospheric CO2 concentrations were set at ambient (400 ppm) or elevated (800 ppm), as per the predictions of the IPCC. As per my hypothesis, the results suggest that these species will become more challenging in future due to increased biomass production, asexual reproduction and a higher C: N ratio which is evident under high CO2 concentrations. Although the biological control agents were in some instances able to reduce this CO2 fertilisation effect, their efficacy was significantly reduced compared with the levels of control observed at ambient CO2. These results suggest that additional biological control agents and other management methods may be needed for continued control of these invasive macrophytes, both in South Africa and further afield where they are problematic.

- Description: This study focuses on the effects of liberalisation and regulation of the telecommunications sector in South Africa. A qualitative research method was adopted and the researcher conducted focus group interviews with participants that were purposely selected to collect data from different suburbs around the Buffalo City Metropolitan area in the Eastern Cape Province, South Africa. The areas were Mdantsane, Selborne and Southernwood, which have large populations and obviously enjoy high cell phone usage. In addition, an in-depth interview was conducted with an official of the Independent Communications Authority of South Africa (ICASA), which is the monitoring body for telecommunications in South Africa. The findings of this study have shown that despite the airtime and data being expensive, the telecoms sector is critical to the people of South Africa, and the failure by the government to regulate and liberalise the telecoms sector has led to expensive cell phone charges on the public. As such, it can be noted that the majority of the urban poor, especially in the Buffalo City Metropolitan, endure expensive charges. More so, the study found that there has been frustrating slow progress of transformation of the telecommunications industry and associated key national policy objectives. In addition, the study also recognises that as a member of WTO South Africa had to adopt policies of globalisation or risk isolation should it operate outside it. In addition, this study revealed that in spite of the challenges that are related to regulation and liberalisation, progress can still be made in reducing price hikes, especially when strategic investments are made in the telecommunication sector in South Africa.

- Description: Using quarterly data from 2003:Q3 to 2017:Q1, this study investigates the effect of the stock and bond markets on economic growth in South Africa. The variables used in the study pertain to South Africa and include the JSE All-Share Index, real effective exchange rate, bond market growth, investment expenditure, inflation rate, government expenditure and gross domestic product. The empirical study is guided by an Autoregressive Distributed Lag (ARDL) model approach which includes unit root tests for stationarity, bounds tests for cointegration and causality tests using the long run and short run error correction models. Diagnostic tests and stability tests are performed on the various econometric models. Tests include the Jarque-Bera test, Ramsey Reset Test, Whites test, CUSUM and CUSUM square test. The findings suggest that the stock market growth and bond market growth have displayed significantly different results with regards to their effects on economic growth. Stock market growth has had a positive impact on economic growth in the long run, whilst growth and development in the bond market does not have a statistically significant relationship with economic growth in the long run. The study provides a solid foundation for establishing the effects of the stock and bond market on economic growth.

- Description: Introduction: Obesity is a metabolic disease in which the accumulation of excessive fat in the adipose tissue may interfere with the normal maintenance of a healthy state. However, there is only a limited number of drugs approved for the treatment of obesity. For this purpose, target therapies are receiving more attention as a preferred treatment to reduce the burden of chronic diseases which are associated with the current strategies. Nanotechnology is a highly promising field that offers a nanotechnology-based drug delivery system as a novel means of solving issues associated with the toxicity of conventional anti-obesity drugs. Vascular targeted nanotherapy (targeted bi-functionalized nanoparticles) as a strategy that can overcome the current available anti-obesity drugs. Aim: This study sought to understand the effects of nanotherapy in the hepatic lipid metabolism and secretion of bile acids Research focus: The effects of gold nanotherapy on the bile acid biosynthetic enzymes, transporters and lipogenic enzymes of rats that were on a high fat diet. Conclusion: The study shows low expression in the majority of genes responsible for bile acid synthesis and a lipogenic pathway; therefore, the effects of nanotherapy exhibit low toxicity in the hepatic lipid metabolism.

- Description: There is a high number of children placed in foster care in the Eastern Cape compared to other provinces as of 2017, this proves that foster care is the most preferred form of substitute care in South Africa. Despite the revelations that foster care is the mostly practiced form of substitute care in South Africa, children do not remain forever in the foster care system. Every year, hundreds of young adults age out of the foster care system in South Africa when they officially become adults at or around their 18th birthday. The aim of the study was to investigate the experiences of youth who have exited the foster care system in Kou-kamma Local Municipality in the Eastern Cape province. A qualitative research method was employed. The study made use of 26 participants, 21 youth who exited the foster care system were purposively selected from all six wards of Kou-kamma Municipality and six social workers were also purposively selected from three child welfare organizations in Kou-kamma Municipality. An interview guide was developed for both sets of participants and they were individually interviewed. The findings show that youth who have been exited from the foster care system experience a series of challenges after they have exited, including experimenting with drugs and alcohol as a negative coping mechanism, unplanned pregnancy, lack of support to enter tertiary education institutions, and financial challenges., Furthermore, the findings indicate that the youth developed coping strategies including working as seasonal workers on fruit farms of the langkloof and in the tourism and forestry of the Tsitsikamma. The youth also reported receiving support from their partners and former foster parents. Support services after the exit from the social service organizations was found to be non-existent and also the fact that social workers were facing a vii number of challenges in their quest to fulfil their roles. Some of these challenges include lack of resources, heavy caseloads, poor remuneration and inadequate office space which led to sharing. It is evident from the study that former foster youth in Koukamma are not exempted, they too encounter a lot of challenges after exiting the foster care system, more especially at the early stage of the exit with no form of support at all from child welfare organizations, they are made to find their own way in life as they are regarded as adults. It is recommended that a multi- stakeholder approach inclusive of different stakeholders needs to be adopted.

- Description: ARF GTPases are key regulators of the secretory and endocytic pathways. ARF1 is involved in the secretory pathway. ARF1 has been implicated in the endoplasmic reticulum to Golgi transport, function of the Golgi apparatus and transport from the trans-Golgi network to endosomes. ARFs cycle between active GTP-bound and inactive GDP-bound conformations. GDP/GTP cycling is regulated by large families of guanine nucleotide exchange factors (GEFs) and GTPase activating proteins (GAPs). ARF GEFs facilitate the activation of ARFs by mediating the exchange of GDP for GTP, while ARF GAPs terminate ARF function by stimulating the hydrolysis of the terminal phosphate group of GTP. Based on existing evidence gained from gene manipulation and cell biological investigations, ARF1 has been shown to be fundamentally important for cancer cell proliferation and metastasis and may be a promising target for the development of anti-cancer drugs. Additionally, the conservation of ARFs in eukaryotic organisms leads to an interesting question of whether a single drug target can be used to target multiple diseases. In this case, can a human cancer drug employed for cancer therapy be used in anti-malarial drug therapies? To confirm the drug target status of ARFs using chemical validation experiments, novel inhibitory compounds are needed. This requires the development of complex in vitro protein- protein interaction assays that can be used to screen chemical libraries for ARF GTPase inhibitors. In this study, we developed a fluorescence resonance energy transfer (FRET) assay and a novel in vitro colorimetric plate-based assay to detect the activation status of truncated human and Plasmodium falciparum ARF1. In the case of the FRET assay, active (GTP-bound) and inactive (GDP-bound) ARF1 could be distinguished with Z-factor values >0.5, suggesting that further development of the assay format to identify GEF and GAP inhibitors may be feasible. In the case of the colorimetric assay, robust signals could be detected and the assay was useful for detecting the activation status of ARF1. However, although the activation of ARF1 by the Sec7 domains of the BIG1 and ARNO was detectable, signals were not robust enough to employ in screening campaigns.

- Description: My novella tells the coming of age story of a young woman battling the trauma of objectification. It explores the intimate relationship between a woman and a man, the young and the old, and the camaraderie between women. Having spent the greater part of her youth in various parts of the world, my protagonist faces the stark reality of returning home to her native country. This triggers an angst which causes her to leap between lived experiences and memories. An elegy on how difficult it is to love while dragging the long shadow of shame, it uses short prose and prose poetry to reveal the intimacies and intricacies of self hate and clandestine romances, and to unravel the complexities of memory and forgetting. Built from non linear fragments it seeks to refuse cliches regarding love and to question easy assumptions around gender, family and the innocence of youth. I draw inspiration from Vita Sackville West’s’ All Passion Spent , which eloquently portrays the placid and flickering thoughts of an old woman taking leave from the frivolity of youth. I’m similarly inspired by the sincerity and confessional aspects of Virginia Woolf and French poet and photographer Alix Roubaud ’s journals and Van Gogh’s letters, as well as Lydia Yuknavitch, Max Porter and Elena Ferante’s autobiographical fiction. I also draw from J’Lyn Chapman’s chapbook A Thing of Shreds and Patches and finally Dostoevky’s Notes from Underground , for their blurring of life and writing, and their exploration of grief and death as a lingering thought, together with the oppressive urge to create. In addition I’m inspired by the poetry of a new generation of South African female writers like Vangile Gatsho.

- Description: This study aims to identify post-apartheid trends of inequality within Port Elizabeth, by analysing the spatial distribution of social well-being from 1996 to 2011. The spatial distribution of social well-being highlights the geography of inequality within Port Elizabeth, focusing on social indicators as a measure of social well-being. Mapping of these social indicators illustrates various levels of social well-being throughout Port Elizabeth based on the formulation of social indicators, application of these social indicators to census data, data processing and mapping. This results in the mapping of poverty, employment, education and standard of living for the census years of 1996, 2001 and 2011. From the mapping process, trends of social well-being and the associated inequality are illustrated and analysed, while providing insight into the progress of social well-being within a South African city. The findings of this study suggest that social well-being has incurred changes over time which have aided in the improvement of social well-being throughout Port Elizabeth. This improvement is marked by the relative increase and decrease of selected social indicators and their interrelated nature. The various social indicators, although focused on different datasets, highlight similar patterns of progress throughout their spatial distribution over time. As such, similar patterns of inequality can be noted throughout Port Elizabeth for various social indicators. Based on these similarities and the trends identified within the spatial distribution of inequality in Port Elizabeth, a progression towards a more even distribution throughout the study area was noted from 1996 through to 2011.

- Description: The Employment Equity Act places a positive obligation on employers to promote workplaces free from unfair discrimination. This obligation is reinforced by section 6 of the Employment Equity Act, commonly referred to as the prohibition clause. The 2014 amendments to the Employment Equity Act specifically introduced provisions relating to Equal Pay for Work of Equal Value which prior to 2014, had no specific provisions to guide employees and employers in relation to claims of discrimination, relating to remuneration and terms and conditions of employment. As such employees had to rely directly on section 6(1) to bring such claims which presented significant problems and challenges with the onus. The second key amendment for our purposes relates to the inclusion of the arbitrary ground under section 6(1) as a ground on which discrimination is also prohibited. In addition to the insertion and specific inclusion into law, the burden of proof in section 11 was also amended and must be read with the prohibition clause. It is this aspect which now confronts us with challenges and divergent approaches by the Courts and the development of the broad versus narrow approach in dealing with the ground of discrimination.

- Description: The purpose of the study was to investigate the impact of agricultural infrastructure on rural livelihoods of kwaZulu-Natal. The main objective of the study is to look into the ways in which rural infrastructure can improve the livelihoods of kwaZulu-Natal farmers. Government programmes such as agri-parks, one household-one hectare and cooperative funding, when implemented according to their objective, can improve the implementation of infrastructure development in rural areas of kwaZulu-Natal. The objectives of the study were achieved by reviewing the literature relevant to the topic. Data was sourced from primary and secondary sources. A qualitative method was used as the qualitative approach has been considered to be the most appropriate method in achieving research objectives. This approach puts emphasis on the meanings and experiences as found in the study of Lincoln and Denzin. This approach best describes events, opinions and views without the use of data in the form of numbers; rather it provides textual data that gives an insight into the occurrence being studied. The developments in agriculture would not be sustainable without developing the rural areas and addressing the issues of poverty and enhancing investment capacities of the resource-poor farmers. The linkage of infrastructure to positive economic development cannot be denied. Agricultural infrastructure is infrastructure such as irrigation, rural electrification, roads, and markets in close coordination with institutional infrastructure. There is a long list of infrastructure assets that affect rural development. There is basic agricultural infrastructure which forms the foundation for agricultural economic development of rural livelihoods. This infrastructure includes transport networks, access to water and livestock agricultural infrastructure. Thus, the study sought to establish the impact of existing agricultural infrastructure on agricultural economic development and improvement of rural livelihoods in kwaZulu-Natal. The study revealed that the rural farmers in this province were affected and limited by poor road infrastructure and that access to suitable water for irrigation was far from ideal. As a result, the sector is hindered and does not perform to its full potential and this slows economic development and negatively affects rural livelihoods.

- Description: The study provides insight into the views and perceptions of consulting engineers on the discounting of professional fees. The purpose of the research was to determine the impact of discounting professional fees in the civil engineering profession and ultimately potential ways in which the civil engineering profession could improve business sustainability. The study included a review of literature, which was utilised to develop a questionnaire. A total of 26 practicing consulting engineers, who are members of Consulting Engineers South Africa (CESA), and represented small, medium and large consulting engineering firms, participated in the questionnaire survey. The questionnaire investigates the respondents’ perceptions on the impact of discounting professional fees in the civil engineering profession and the amount of discount offered as well as the reasons for discounting fees. The results show that the practice of discounting professional fees is widespread, affecting small, medium and large consulting firms. The results also indicate that prevailing market conditions in civil engineering profession are the primary reasons why consulting engineers offer discounts on fees. Respondents agreed that projects are awarded to the lowest bidder during tender process. Respondents also agreed that experienced engineers are allocated less time on projects to manage project costs. The findings suggest that discounting of professional fees is a great concern that needs to be addressed in order to attain profession business sustainability. It is suggested that the Engineering Council of South Africa (ECSA) should regulate the fee structures and ensure that all professionals, whether employed in the public or private sector, understand the basic finances on running a professional consultancy to deliver a service.

- Description: In the fast-paced world of today, innovation is more relevant now than at any other time in our history. The dynamic nature of today’s business landscape presents complex challenges to organisations at macro and micro environment levels. To survive these challenging times, innovation has been identified to play a vital part in finding and developing opportunities for growth and sustaining a competitive edge. It is with no surprise that researchers have long sought to find the root drivers of great innovation. The consensus is that employees are the engine behind innovation and that innovation within an organisation is a direct result of employees engaging in innovative behaviour. Organisations that fail to tap into the creative potential of their employees lose out on benefits and advantages of being innovative organisations. There are various factors that influence employees’ engagement in innovative behaviour, and research into the topic has considered the influence of different factors such as: individual traits, natural inclinations to innovation, motivation, emotions, organisational culture, job requirements, leadership, and social relations. The purpose of this study was to empirically investigate the influence and significance of job satisfaction, perceived colleague support, perceived leadership support, perceived organisational support and job stress on employees’ engagement in innovative behaviour. Based on a review of current literature, the study investigated hypothesised direct and indirect relationships that exist between these factors and that can be used to improve the levels of employees’ engagement in innovation behaviour in Eskom distribution in the Eastern Cape operating unit. The study used on-line questionnaires to survey Eskom Distribution ECOU employees. 141 employees participated in the survey. Majority of the respondents were males and were from Specialised Maintenance and Support department. A large number of the respondents are university and Technikon graduates with half a decade or more in years of service to Eskom. The results of the survey show that there is a significant positive relationship between job satisfaction, colleague support, leadership support organisational support and innovative behavior. From this finding the researcher recommended that management that improves the levels of employee engagement in innovative behaviour by focusing on issues pertaining to job satisfaction, colleague support, leadership support and organisational support.

- Description: Globalisation, technological advancement and currency regulations are key motivators for companies to invest in foreign countries. As new entrants enter the market companies are faced with the threat of market share loss due to increased competition. The increase in the global competitive landscape has a direct impact on the rise of Mergers and Acquisitions (M&A). The growth potential of companies that experienced mergers has resulted in the boom of M&A over the past three decades. In most cases M&A have resulted in job losses and in some demotions. It is no surprise that these transactions result in an anxious and stressed workforce. The merger of the three soft drink bottlers in South Africa namely: CCF, Shanduka and ABI has brought about changes that have left some employees feeling anxious about the future. The combining of different cultures from the different entities can have a negative effect on employees as they would need to adapt to a different culture of the new formed entity. M&A were first introduced in the United States during the eighteenth century and moved into Europe in the nineteenth century. A large body of research has been concentrated in the United States and European markets to understand phenomena relating to such activities in developed countries. M&A activities have also transcended into developing countries. Over the past few years M&A transactions have become a critical gateway for investment in Africa for both local and universal market players. The aim of the study is to understand the employees’ state of mind in the workplace after the merger. The results of the study show that employee morale prior to the merger was higher when compared to post the merger, which implies that employee morale has declined post the merger. The results indicate that after the merger there was a significant decrease in trust, motivation, employee well-being and job satisfaction.

These methods enabled an in-depth understanding of minimum wages. Thus in-depth, semi-structured interviews were conducted as they provided detailed information by enabling the researcher and the participant to have an informal, but expressive conversation about the minimum wage. Contrary to the assumptions of orthodox economics, which claim minimum wages create a ‘shock’ resulting in job losses, this research found that the minimum wage was absorbed causing few disruptions in existing work and employment relations in the selected establishments. This capacity to absorb the minimum wage is largely the outcome of informal labour relations policies and practices.

- Description: Namibia is a member country of the Common Monetary Area (CMA) with Lesotho, Swaziland and South Africa. South Africa is the anchor country to which the smaller member states have surrendered monetary policy authority. This thesis therefore examines the empirical relationship between the South Africa repo rate (SArepo) on the one hand and Namibia’s repo rate (Namrepo), Prime Lending Rate (PLR), Private Sector Credit Extension (PSCE), Consumer Price Index (CPI) and Gross Domestic Product (GDP) on the other hand. The credit channel of the monetary policy transmission mechanism informs the theoretical foundation of the thesis. Vector Autoregression modelling, variance decomposition and impulse response functions were used to explore the nature and strength of the relationship between the SArepo and said variables in Namibia. This thesis used quarterly data for the period 2003 to 2017. The variation in the Namrepo was predominantly explained by the SArepo, which confirmed that the Namrepo strongly followed the SArepo. The impulse response function results found that the impact of a contractionary monetary policy shock (an increase in the SArepo) lasted for up to six quarters before the effect started to fade. The Namrepo exhibited a positive response to an increase in the SArepo, although the magnitude of the response started to fade after the third quarter. The PLR, as a representative of market rates in Namibia, also exhibited a positive response to an increase in the SArepo. The results were similar for the Namrepo and the PLR because changes to the NamRepo are passed through immediately to the market interest rates. On the real variables, the study found that a contractionary monetary policy shock initiated in South Africa resulted in an increase in inflation in Namibia of less than 0.4 percent, whereas output declined by less than 1.0 percent. Interestingly, a Namibia (domestic) contractionary monetary policy shock resulted in a decline in prices of less than 0.4 percent. GDP, on the other hand, exhibited a positive response to a contractionary monetary shock, with an increase of less than 2.0 percent in the first four quarters of the period observed. The results reflected that a contractionary monetary policy shock from South Africa was more effective with regard to its impact on GDP; however, a domestic monetary policy shock was more effective at impacting on domestic inflation compared to the impact from South Africa.

- Description: Prominent German automotive manufacturers had been tampering with emissions for some time before it became public knowledge in September 2015. It is then that that the term ‘Dieselgate’ was coined in reference to the scandal. As the scandal became public knowledge, manufacturers accused of emissions cheating faced challenges on several fronts, including legal, financial and environmental. While the ‘backlash’ as a result of the scandal was apparent in other countries, it was not as apparent in South Africa. This research paper set out to explore the impact that the Dieselgate scandal had in South Africa in terms of customer equity. Data analysis was undertaken using a two-pronged approach. The first of these was analysis of vehicle sales data using a paired t-test. This was to understand whether sales had seen a decline pre-, as well as post-scandal. The results point to a sales decline, this highlights that Dieselgate was a factor even though other, unexamined factors, were not investigated. The second instrument used was a customer equity questionnaire, this provided insight into the real opinions of consumers in South Africa about the affected brands. The analysis revealed that the affected manufacturers operating in South Africa had seen no negative effects in terms of customer equity. Based on the results, it could be said that market factors, which was not part of the research, play a great role in consumers’ preferences or mindsets. Additionally, manufacturers can operate with a degree of latitude in certain markets. This is based on market factors in a specific market as well as the regulations imposed and enforced in that market. Lastly, customer equity is a complex theory that includes a multitude of converging theories. Based on this fact, it is currently difficult to evaluate customer equity in its entirety in a single paper. A comprehensive model is yet to be developed that can effectively measure customer equity in an all-encompassing way.

- Description: This dissertation endeavours to unpack and understand the impact of the minimum wage on the hospitality industry with a specific focus on Grahamstown. The areas of impact that are of immediate interest were the impact on poverty and industrial relations. In operationalising this research, a qualitative research approach was adopted. The overall design of the study was a case study in a bid to ensure deeper insights may be extracted from semi-structured interviews that were then thematically analysed. Theoretically, the study was guided by the understanding of citizenship as articulated by Mamdani as well as Keynesian theory. The central theme when exploring the minimum wage in relation to poverty is that the minimum wage that is currently paid is enough to aid workers and their families in escaping abject poverty, however, it does not go far enough to further ensure that they totally escape poverty as measured by the Upper Bound Poverty Line. The inadequacy of the minimum wage in ensuring that people are pushed out of poverty would then mean that their claims to citizenship are compromised and the quality of life they can access is often below what would be readily accepted of a citizen of South Africa. Lifestyle entrepreneurs offer an alternative approach to doing business that can see higher pay as further entrench claims to citizenship. The central case around industrial relations is that the impact of the minimum wage is indeterminate for two reasons. Broadly speaking, the impact would need to be reviewed at a macro-level and not simply within the impacted sectors. This is the various interconnected value chains that could feel indirect impacts at the initiation of a minimum wage. Further, the impact such changes has to individual firms is also indeterminate as employers have a range of choices that they can adopt in absorbing the impact of a minimum wage, which may include simply increasing the price the end consumer pays or retrenching some staff members. However, the choice that employers would make in this context is not predetermined but rather would vary between firms due to the very specifics of each firm.

- Description: This study investigated the implementation of Grade R admission policy in Mopani District in Limpopo Province and focussed on four primary schools in Makhutswe circuit which has got Grade R classes. The interpretive paradigm was applied as the chosen methodology for the study. Data were collected through semi-structured interviews and focus group interviews. A review of secondary sources to corroborate the gathered information was also used. Data analysis was done using thematic analysis through emerging themes from the transcribed data from the interviews. The participants were purposively selected for the sample of this study. These included 1 principal per school, 1 Grade R educator per school, 5 SGB members per school, and 2 admission committee members per school. Through the participant’s responses from the schools under study, a transcript was formulated, coded, and categorized in view of the implementation of the Grade R Admission Policy in primary schools. The study found out that the admission policy for Grade R learners was not properly implemented in most of the primary schools due to lack of understanding how the policy must be implemented. It was also revealed that, most of the principals together with their admission committee members tend to use their own discretion concerning the admission of Grade R learners in schools. It further emerged that some of the learners denied admission despite the existing legislation that proscribes that every child has the right to education. Furthermore, the study found out that the district office did not involve the primary teachers before formulating the policy. Hence, the participants showed that they did not have good and proper understanding of the implementation process neither were they well versed about what entailed monitoring the admission policy. As a result, Department of Education resorted to coming up with ways of continuously training and conducting workshops for the educators before they can admit learners to Grade R.

- Description: The aim of the study was to investigate the implementation of the Back-to-Basics (B2B) programme in Raymond Mhlaba Municipality. The study used qualitative research design and data was collected using in-depth interviews. The finding of the study revealed that the municipality was able to sufficiently implement the appropriate B2B programme in the community areas. Moreover, the findings identified corruption and mismanagement of funds, improper understanding of the municipality’s IDP and the roles of different government departments, poor communication skills between the municipality ward councillors and the community members, as well as poor service delivery as some of the challenges faced by Raymond Mhlaba Municipality in implementing the Back-To-Basics programmes. Importantly, in respective community areas, the findings revealed that water crises, empty promises and unrealistic/fake promises are some of the negative impacts the community members experienced during the implementation of the B2B programme, which brought little growth and development to the communities. Besides, the findings revealed that the implementation of this programme created employment opportunities for the unemployed youths in the communities. The study, however, concluded that the municipality is not doing enough in the implementation of B2B programme as many communities still complain of poor service delivery. Hence, for effectiveness in the implementation of B2B programme, it is important that the municipality delegates powers to the ward councillors. Furthermore, municipality management needs to refrain from making empty promises to the communities, they must be honest and deliver qualitative services to communities. However, community members should show signs of appreciation to all municipal activities, as well be supportive and ii show lots of interest and willingness attending the municipality’s manifestoes. Finally, the municipality management should ensure transparency, effective communication with the community members, provision of good service delivery, fulfilment of promises, honesty, proper budgetary allocation and spending, effective monitoring and evaluation of the municipal officials, as well as avoiding of nepotism in awarding tenders for the purpose of achieving a smooth running of the municipality.

- Description: The study sought to establish how the indigenisation policy solves women discrimination by empowering them through the Community Share Ownership Trust revenue. Literature reveals that Zimbabwe was not the first country to implement the indigenization policy as it was implemented in neighbouring countries. The aim of the policy was to disempower foreign investors and empower local people with the aim of lifting up the standards of the discriminated and less privileged, such as women. Based on the results, the study establishes and concludes that discrimination of women was poorly addressed by the indigenization policy due to some factors such as poor presentation of women in the law-making bodies, patriarchal dominance as well as cultural beliefs that supress women, and lack of clarity on policy objectives. Therefore, a top-down approach was used to address the problem of discrimination faced by women at market place. As a result the approach yielded a negative outcome because empowerment of women without women ideas is impossible. Basic Need Approach (BNA) and Capability Approach (CA) are the two approaches discussed in relation to women and Indigenization, Economic and Empowerment policy in Zimbabwe, with a case reference to Mhondoro-Ngezi district. More preference was given to the capability approach. This was so because it helps to explain the abilities and potential in women as entrepreneurs who produce outcomes to development of society and the nation at large. The study was qualitative in nature of which descriptive research design was employed where semi-structured interviews and focus group discussions were used as research tools.
