- Description: The challenge posed by multicultural classrooms has been acknowledged in many studies. Some scholars believe that the knowledge learners bring to school from their homes or community forms a basis for the knowledge to be acquired at school. That is, if learners’ cultural experiences and/or indigenous knowledge are integrated into teaching of science, learners might make good sense of science. Even though the Namibian National Curriculum has responded well to the calls of recognising and integrating indigeno us knowledge during teaching and learning, it has failed to provide guidance on how this should be done. Therefore, there is a need to minimise the gap between the intention of the National Curriculum and the implementation of this intended curriculum at classroom level. It is against this background that this study sought to investigate whether or not learners’ conceptions and attitudes are influenced by integrating local or indigenous knowledge when teaching food preservation in a Namibian multicultural classroom context. Underpinned by an interpretive paradigm, the study took the form of a mixed-method case study approach. It was conducted at an urban combined school in the Oshana region, Namibia. The sample consisted of 29 Grade 6 learners doing Agricultural Science, the grade 6 Agricultural Science teacher and four community members from different cultural groups. The community members were invited to demonstrate how they culturally preserve mahangu (wheat), fish, milk, and meat in their respective cultures. Data were generated using the pre-and post-intervention questionnaires, a group activity, observations (videotaped lessons) and learners’ journal reflections. Quantitative data from the pre- and post-intervention questionnaires were analysed deductively and presented in tables and graphs. On the other hand, a thematic approach was used to inductively analyse qualitative data, where Vygotsky’s (1978) socio-cultural theory was used as a theoretical lens focusing on culture, mediation, and social interactions. The findings of this study revealed that learners’ conceptions, attitudes, and interest shifted positively as a result of the integration of local or indigenous knowledge on food preservation. Additionally, during the presentations by the community members, learners were actively engaged, asking questions and showing interest in learning about other cultures. The study thus recommends that Agricultural Science or science teachers should, where possible, make efforts to integrate local or indigenous knowledge in their multicultural classrooms.

- Description: Since the adoption and implementation of the South African Schools Act of (1996), School Governing Bodies (SGBs) have been provided with the powers to recommend the employment of teachers in schools. Moreover, SGBs are also required to have an impact on the promotion of diversity in schools through the employment of teachers in a non-discriminatory way. However, two decades since SASA of 1996, Foundation Phase teaching remains dominated by females. Literature in the South African context posits that gendered schooling practices still exist in the differentiated opportunities of the employment of teachers. Particularly male teachers eager to teach in the foundation phase in the Eastern Cape, KwaZulu-Natal and North West Province. The study sought to explore the perceptions of SGB members towards foundation phase male teachers in the Eastern Cape schools. This study employed Participatory Visual Research Methodologies (PVRM), as its research design and was underpinned by the critical paradigm. It utilised a participatory method, collages and a focus group discussion to generate data with five SGB members from three purposively selected schools in the Eastern Cape. The study utilised a feminist post-structural theory in the analysis of findings. The findings revealed three themes, which are; (1) Males are not seen as good caregivers, (2) Foundation phase male teachers are seen as multifaceted and lastly (3) Male teachers are seen as not suitable for Foundation Phase teaching. Each of the above findings offers recommendations to the following stakeholders, the Department of Basic Education (DBE), Department of Higher Education and Training (DHET) and for future research.

- Description: The fabricating of metal oxide thin films onto conducting surfaces continues to grow and their potential applications as surfaces for biosensor applications is of paramount importance. The correct orientation of glucose oxidase redox enzymes yields very important biointerfaces capable of selectively detecting D-glucose as a measure of blood sugar for healthy and diabetic sick patients. The electrodeposition of redox enzymes, such as glucose oxidase enzymes, onto gold electrode surfaces pre-modified with nickel oxide was investigated in this work.

- Description: There is a dearth of publications on women’s use of TMPs during the perinatal period. (Nergard et al., 2015). It is recommended that “plants used by pregnant women need to be better known in order to ensure that pregnant women receive effective treatment, to identify potentially unsafe use, and also to preserve valuable information about medicinal plants for women’s reproductive health for the future” (Nergard et al., 2015). Tripathi, Stanton and Anderson (2013:16) conclude that “[f]urther research is needed on the uterotonic efficacy of traditional preparations and on interventions to address the use [of TMPs] during labour”. Gruber and O’Brien (2011:218) support the statement and argue that the search for a “novel cyclotide-producing plant…may eventually lead to the development of novel uterotonic …drugs”. Pharmacological evidence of TMPs may promote the safe use of TMPs by IKHs during birth and the postpartum period. Kaingu, Oduma and Kanui (2011:495) emphasized that TBAs still have a crucial role to play in society, by assisting labouring women in rural communities and their “knowledge on medicinal plants is equally important and should be preserved for posterity”.

- Description: Healthcare has been identified as a basic need and one of the key economic drivers in South Africa (Pravin Gordhan, 2017). With the majority of South Africans reliant on the public health sector for the management, the prevention and cure of all their healthcare issues and needs come the dire requirement of exceptional skills from healthcare professionals. Hospital and clinical managers play the dual role of clinician and manager, often without proper management training. With the impending introduction of the National Health Insurance (NHI) and ever-challenging constraints of medico-legal litigation on healthcare, it is imperative that healthcare professionals are adequately equipped with the core management competencies. The aim of the study is to identify management competencies of Clinical and Hospital managers and establish an implication/indication for further management training. This study used competencies identified in healthcare management courses currently offered in South Africa in conjunction with literature reviewed. A sample population of Clinical and Hospital managers in the public sector of the Eastern Cape was used using a non-random purposive/judgement probability sampling technique–the “snowball” sampling technique. The questionnaire link (Questionpro) was distributed to all respondents via email and WhatsApp distribution followed from the Eastern Cape Department of Health Head Office to the Chief Executive Officers of hospitals in the Eastern Cape and the Human Resources Director of the Eastern Cape Department of Health. The online link was made available for completion; thereafter data was collated and analysed using the STATISTICA programme. Based on a literature review, the theoretical model proposed six core competencies-leadership, risk management, financial management, corporate governance and ethics, people/human resources management and quality and evidence-based management. Of the six competencies, Clinical and Hospital Managers exhibited Leadership, Corporate Governance and Ethics and Quality and Evidence-based Management in high levels. The qualitative analysis demonstrated respondents’ intentions to study further, often in management fields and shared a unanimous need for management training for better job efficacy and performance. The researcher has made recommendations to aid in improving management skills as well as areas for further research such as short courses and mentorship programmes and further comparative studies between the private and public sector. The study concluded that management competencies are significant for Clinical and Hospital Managers and should be addressed in the future to aid in better clinical outcomes.

- Description: The southeast coast of Madagascar, namely the region surrounding the town of Fort Dauphin, is an area that regularly experiences upwelling events. Two unique high frequency data sets, UTR data, and wind data retrieved from a nearby airport, are the primary data sets used to investigate the nature of the upwelling, i.e. the area that experiences upwelling, how often it occurs, and its mechanisms. To complement the in-situ data, several different satellite data sources are used alongside the in-situ data to study this relatively remote region, i.e. SST, chlorophyll-a concentration, current, and wind data. The results refine upon previous literature on the topic. The upwelling covers an area of 1o latitude by 1.3o longitude, and occurs on average 14 times per annum. The mechanism driving the upwelling can be attributed to both wind and current, with wind the more dominant driver along the south coast, and current more dominant along the east coast. Separate to the main objective of the thesis is the importance of in-situ data when analysing small scale events such as upwelling events. While the in-situ wind data were found to be unreliable due to its location within a valley, the UTR data were of vital importance in identifying and studying the finer details of the upwelling events. The satellite SST data, by comparison, were lacking in their ability to investigate the upwelling events. The satellite derived wind data, however, did prove useful when analysing the wind as a driver of the upwelling.

- Description: In South Africa, Psychology has had a chequered past mainly due to its role in the justification of apartheid policies. Due to apartheid's socio-economic injustices, confidence in the applicability of psychological knowledge to South Africa's social problems was insufficient. Psychologists attempted to raise consciousness of the social relevance of psychology by contributing relevant knowledge and being reactive to social inequalities and related psychosocial issues affecting South Africa. This study aimed to conduct a content analysis of trends in research produced by Psychology Masters' students in the fields of Clinical, Counselling and Research psychology over a period of 5 years (2008-2012). The corpus of data was then compared with the key issues raised in the United Nations Development Programme's South Africa human development report (2003), along with a focus on articles published by Macleod (2004) and Macleod and Howell (2013). It emerged that Empirical Qualitative studies, based on post-modern frameworks, as well as HIV/AIDS, Knowledge Production, Assessment and Measurement and Programme development and evaluation, dominated psychological research. Participants were mainly urban, middle class adults living in the 3 wealthiest provinces. University students were the most popular participant group. While it is encouraging that students were attempting to engage with psychosocial issues, the limited number of key social issues addressed, the under-representation of certain sectors of the South African population, as well as the impact of socioeconomic status on well-being requires greater attention at Masters' level to ensure Psychology's psychosocial relevance.

SAR studies revealed that an OH group and rotatable C–NH bond are vital for biological activity, with spectrophotometric techniques and docking simulations suggesting a dual mode of action involving hemozoin inhibition and DNA interaction. Targeting multiple pathways could delay the development of clinical resistance.

- Description: The exponential growth of technology over the past few years has given rise to the term Industry 4.0. The term Industry 4.0 has since gained increasing relevance and importance. Klaus Schwab, founder of the World Economic Forum (WEF) emphasised that the world is on the verge of a technological revolution that will profoundly alter the way we live, work and relate to one another; and that the scale, scope and complexity of the transformation will be unlike anything humankind has experienced before (Schwab, 2016). Industry 4.0 is said to be unlike the previous three industrial revolutions, it is a distinct one of speed, extent and systems impact, characterised by a major disruption to all sectors of business, governments and individuals globally.

- Description: The exponential growth of technology over the past few years has given rise to the term Industry 4.0. The term Industry 4.0 has since gained increasing relevance and importance. Klaus Schwab, founder of the World Economic Forum (WEF) emphasised that the world is on the verge of a technological revolution that will profoundly alter the way we live, work and relate to one another; and that the scale, scope and complexity of the transformation will be unlike anything humankind has experienced before (Schwab, 2016). Industry 4.0 is said to be unlike the previous three industrial revolutions, it is a distinct one of speed, extent and systems impact, characterised by a major disruption to all sectors of business, governments and individuals globally. Industry’s such as insurance, is considered conservative and slow to change, as such the industry has never been quick to adapt to technological advancements. One thing however, that is certain about Industry 4.0 and predicted by many, is its significant impact on jobs in the world as robotics; automation and artificial intelligence become more abundant.

- Description: Reflection is the core aspect in many teacher education programmes around the world, South Africa included. The Department of Higher Education and Training (DHET) regards reflection as a vital tool in integrating theoretical and practical knowledge gained in university coursework with practical knowledge obtained in the school classroom context. Literature highlighted that student teachers do not engage in reflection effectively, especially within the context of African language literacy teaching, thus they feel unprepared to deal with the complexities in classrooms. This has negative repercussions on how learners are taught and achieve their educational attainments. The main aim of this study was to explore and describe student teachers’ selfreflections on implementing isiXhosa literacy strategies with Grade 3 learners. This study further sought to understand their reflections on integrating theory and practice as well as their successes and challenges of implementing theoretical knowledge. The main argument of this study is that reflective thinking is a complex and valuable tool that can be utilised to provide quality teaching and learning. In this qualitative single case study premised on an interpretivist paradigm, I purposively selected student teachers and generated data through classroom observations, individual semi-structured interviews and reflective journals. Data was analysed through thematic analysis and two themes emerged. The findings revealed that student teachers used a learner-centred approach to teach isiXhosa literacy in Grade 3 classrooms. Moreover, it revealed that student teachers experienced curriculum demands that inhibited them from implementing isiXhosa literacy strategies efficiently. Conclusions were made based on ideas of sociocultural theory, the reflective thinking model and literature. From these findings, several recommendations were made for student teachers, literacy teacher educators, mentor teachers and policy makers.

- Description: The forthcoming Square Kilometre Array is expected to provide answers to some of the most intriguing questions about our Universe. However, as it is already noticeable from MeerKAT and other precursors, the amounts of data produced by these new instruments are significantly challenging to calibrate and image. Calibration of radio interferometric data is usually biased by incomplete sky models and radio frequency interference (RFI) resulting in calibration artefacts that limit the dynamic range and image fidelity of the resulting images. One of the most noticeable of these artefacts is the formation of spurious sources which causes suppression of real emissions. Fortunately, it has been shown that calibration algorithms employing heavy-tailed likelihood functions are less susceptible to this due to their robustness against outliers. Leveraging on recent developments in the field of complex optimisation, we implement a robust calibration algorithm using a Student’s t likelihood function and Wirtinger derivatives. The new algorithm, dubbed the robust solver, is incorporated as a subroutine into the newly released calibration software package CubiCal. We perform statistical analysis on the distribution of visibilities and provide an insight into the functioning of the robust solver and describe different scenarios where it will improve calibration. We use simulations to show that the robust solver effectively reduces the amount of flux suppressed from unmodelled sources both in direction independent and direction dependent calibration. Furthermore, the robust solver is shown to successfully mitigate the effects of low-level RFI when applied to a simulated and a real VLA dataset. Finally, we demonstrate that there are close links between the amount of flux suppressed from sources, the effects of the RFI and the employed solution interval during radio interferometric calibration. Hence, we investigate the effects of solution intervals and the different factors to consider in order to select adequate solution intervals. Furthermore, we propose a practical brute force method for selecting optimal solution intervals. The proposed method is successfully applied to a VLA dataset.

- Description: Tuberculosis (TB) is a devastating infectious disease caused by Mycobacterium tuberculosis and is the leading cause of death from a single infectious agent. The high morbidity and mortality rates of TB are partly due to factors such as the lengthy regimen (of 6–24 months), the development of drug resistance, and the pathogen location within the macrophages. These, with poor physiochemical properties of existing drugs hamper the effectiveness of the treatment despite the existence of potent antibiotics such as Rifampicin (Rif). Hydrophobicity plagues many drugs, including Rif, which are then particularly affected due to inherently poor intracellular availability. Novel drug delivery approaches are therefore needed in order to optimize the cytotoxic potential of said antitubercular drugs. To improve the bioavailability of hydrophobic drugs, numerous delivery strategies have been developed. Amongst these, the coordination of cytotoxic drugs to therapeutic proteins have shown some success for improved efficacy in the management of illnesses including infectious diseases. Of therapeutic proteins, Human Serum Albumin (HSA) is an attractive drug carrier with interesting benefits such as low immunogenicity, antioxidant properties and improving cellular uptake of drugs through HSA-specific binding sites which are expressed on most cells including macrophages, where M. tuberculosis often resides. Hence, combination of Rif to HSA (Rif-HSA) seems a promising approach for improved intracellular delivery of Rif. However, the in vivo stability of colloidal protein-based therapeutics is mostly challenging and an effective vehicle is needed to control the biological fate of such conjugates. Liposomes seem to be appropriate carriers for the Rif-HSA complex due to their reputable applicability for encapsulating diverse materials (i.e., hydrophobic and hydrophilic compounds or small and complex molecules) and preventing chemical and biological degradation of the cargo. Therefore, the main objective of this study was to simultaneously encapsulate Rif and HSA in liposomes, which, to the best of our knowledge, has not been done before. The dual liposomes (Rif-HSA-lip) were made by a modified “Reverse Phase Evaporation” method (REV), following a Design of Experiments (DOE) approach to determine which factors impact the formulation. In addition, liposomes were made from crude soybean lecithin (CSL), rather than expensive and highly purified lipids. iv The liposomes were fully characterised, and the encapsulation efficiency (î) was monitored using high-performance liquid chromatography (HPLC). The results were correlated with factors such as organic and aqueous phase composition, as well as the in vitro release profile of Rif. Transmission electron microscopy (TEM) results confirmed the formation of spherical dual liposomes nanoparticles of roughly 200 nm. Dynamic light scattering (DLS) and Zeta potential measurements showed a negative charge (<–45 mV) and with satisfactory polydispersity (PDI<0.5). HSA dramatically improved the aqueous solubility of Rif (from1.9 mg/ml in water to around 4.3 mg/ml in HSA 10% solution) mainly due to Rif-HSA hydrophobic interactions. This resulted in a good î of almost 60% for Rif, despite the presence of bulky HSA in the lipid bilayer. These details were confirmed using proton nuclear magnetic resonance (1H NMR) and Fourier-transform infrared spectroscopy (FTIR). Furthermore, energy dispersive X-ray (EDX) and DLS data suggested the presence of HSA poking out on the surface of liposomes, which is encouraging for potential targeted delivery in the future. The in vitro release studies also depicted a substantial improvement in the diffusion of Rif in dual liposomes versus free Rif, from 65% after 12 hours for free Rif to 95% after only 5 hours for Rif- HSA-lip. Finally, stability studies conducted over 30 days at room temperature, showed that the freeze-dried formulations of Rif-HSA-lip exhibited good shelf stability over liposomes with no HSA. This study represents an illustrative example of co-loading of antibiotics and proteins into liposomes, which could encourage further development of novel nanoparticulate tools for the effective management of both drug-susceptible and -resistant infectious diseases such as TB.

- Description: Sagittaria platyphylla (Engelm.) J.G.Sm. (Alismataceae), commonly known as Delta arrowhead, is an invasive aquatic macrophyte native to southern United States of America (USA) that has become a serious weed in freshwater systems in South Africa, New Zealand, Australia, and recently China. In South Africa, the plant was first detected in Krantzkloof Nature Reserve, KwaZulu-Natal Province in 2008, and due to its known impact in other countries, it was listed as a Category 1a invader species under the National Environmental Management: Biodiversity Act 2004 (NEM: BA). This listing required mechanical and chemical control methods to be implemented by the South African National Biodiversity Institute’s (SANBI), Invasive Species Programme (ISP), with the aim of eradicating the weed. Despite the eradication efforts, by 2016, the weed was recognized as one of the country’s top 10 worst and fastest spreading invasive alien plants. Since its introduction in 2008, the plant has spread both within and between sites in South Africa, increasing from one site in 2008 to 72 sites by 2019. Once introduced into lotic systems, the plant spread rapidly downstream, in some cases up to 120km within six years, with an average of 10 km per year. Extirpation over the last ten years was only possible at a limited number of sites. Under the current management approach, the invasion is foreseen to spread to new sites within a 5 km radius of the current populations. Due to the failure of conventional control mechanisms, biological control is currently being considered as a potential control option. Four potential biological control agents are under investigation, but none have been released. Amongst them is the fruit and flower feeding weevil Listronotus appendiculatus Bohm. (Coleoptera: Curculionidae) which showed most potential as a suitable biological control agent. This study demonstrated that L. appendiculatus herbivory negatively influenced the overall fitness of S. platyphylla by reducing the plant’s growth rate and above ground biomass. Listronotus appendiculatus herbivory also reduced the plant’s size and the potential to kill adult plants. Most importantly, L. appendiculatus larval feeding damage significantly reduce viable-germinating seeds, the weed’s primary dispersal mechanism. Therefore, a biological control programme is advised to be integrated within the current management plan.

- Description: This work reports on the photophysical, nonlinear absorption and optical limiting properties of detonation nanodiamonds (DNDs)-silicon phthalocyanine nanoconjugate systems. Si(IV) hydroxide phthalocyanines employed are: 2,9(10),16(17),23(24)-tetrakis-(4-pyridyloxy) phthalocyaninato (Si(OH)2TPPc), 2,9(10),16(17),23(24)-tetrakis-(4-tert-butyl) phthalocyanato (Si(OH)2TBPc) and phthalocyanato(Si(OH)2Pc). Pcs were covalently linked to nanondiamonds and investigated using 532 nm laser excitation at 7 ns pulses for their optical limiting properties. Si(OH)2TBPc and Si(OH)2Pc gave larger triplet quantum yields when linked to DNDs, while the value decreased for Si(OH)2TPPc in the presence of DNDs due to aggregation. However all Pcs showed enhanced nonlinear optical properties in the presence of DNDs. DNDs-Si(OH)2TPPc and DNDs-Si (OH)2TBPc gave the highest imaginary third-order susceptibility (Im[X(3)]) and hyperpolarizability (γ) at 5.19 × 10−8 and 3.85 × 10−8 esu and 2.66 × 10−27 and 1.97 × 10−27 esu, respectively. DNDs-Si(OH)2TBPc nanoconjugates showed lowest limiting threshold (Ilim) value of 0.01 J.cm−2 relative to 0.09 for DNDs-Si (OH)2TPPc.

- Description: This study explored the effectiveness of HIV/AIDS programmes in tertiary institutions in South Africa, and used the University of Forte Hare as a research domain. The study entailed making a cross-examination of the UFH HIV/AIDS programmes in an attempt to test the effectiveness of HIV/AIDS programmes in South African Universities. The study had three objectives, which were to establish the perceptions of the UFH stakeholders pertaining HIV/AIDS programmes; to document the HIV/AIDS programmes offered at UFH; and to determine the resources available to implement the HIV/AIDS Programmes at UFH. The study used mixed methods, that is, incorporating both quantitative and qualitative approaches. The study used combined methods of data collection and instruments, such as in-depth interviews, focus groups interviews, key informants, and a questionnaire. The study adopted Structural Functionalist Theory. The researcher drew a sample of forty (40) participants from the UFH community. Thirty-three (33) student respondents were provided with questionnaire interview; while 5 (five) members of the staff; two (2) members of the UFH HIV/AIDS managers; and two (2) members of administration were interviewed. The study used a combination of both probability and non-probability sampling methods, specifically purposive sampling and systematic sampling methods to select the participants. The data was analyzed using a qualitative and quantitative approaches. The study established that there was inadequacy of financial and material resources to support the implementation of the programmes; inconsistency in condom distribution on campus; limited and unprofessional HIV/AID workers at the UFH campus; availability of various HIV/AIDS programme activities; adequate support structures but failing to be responsive towards HIV/AIDS; and adequate HIV/AIDS knowledge among the students.

- Description: The study is a psychobiographical case study based on the life of a Victorian baby farmer Amelia Dyer (1837-1896). She was executed for the murder of babies who were placed in her care over a period of 30 years. Psychobiography is a qualitative method of enquiry which explores the life of a unique individual subject through the lens of a psychological theory for the purpose of creating a coherent psychological case study. The psychoanalytic theoretical lens of Karen Horney was used to trace the evolution of Amelia Dyer’s sense of self within the Victorian culture of respectability. Baby farming referred to an unregulated business of adoption and fostering of infants, mostly illegitimate infants for a fee. Insufficient social structures and support for unwed mothers and children encouraged the business practice as women had very little choice for childcare. Baby farming was open to abuse and exploitation and hundreds of babies lost their lives due to insufficient care or infanticide. Amelia Dyer showed special talents and creativity from a young age, was ambitious and wanted to be self-reliant in a culture that did not provide women with opportunities to live out their ambitions. Baby farming became a business venture for her in the early stages of her life which later evolved into sadistic abuse and murder of the infants. Her evolution from a creative and hardworking young girl to a sadistic murderer of children is what qualifies her as a suitable subject for the exploration of Karen Horney’s dynamic theory of neuroses and the development of the neurotic self within culture. Extensive biographical data was collected and processed into salient themes. The study integrates the theory of Karen Horney, the life experiences of Amelia Dyer and Victorian respectability and demonstrates the value of using psychobiography as the method of inquiry into the exploration of the unique individual. The findings of the study demonstrated that Amelia Dyer and her social context were inextricably bound by a vicious cycle of psychic and emotional vi conflicts related to fear, control and self-hatred by the internalization of gender stereotypes and norms. The contribution of the study as a whole rests with its demonstration of the value of a holistic and reflexive exploration of the unique individual woman. It demonstrates the value of Horney’s in-depth theoretical understanding of the ambivalent core of selfhood that lies behind observable acts of behavior. The study as a whole contributes towards building upon holistic and integrative therapeutic frameworks in the understanding of diversity amongst women and mothers in culture.

Towards a community-based model for Agricultural development in Uganda : a case study of Kumi and Gomba districts

- Description: This study intended to design a community-based model for agricultural development in Uganda, using Kumi and Gomba districts as case studies. The surge in attention towards community-based development is attributed to the growing challenges posed by the traditional approaches to community development, dominated by top-down mechanisms during the planning, implementation, management, monitoring, and evaluation phases of community development programmes. Driven by Robert Chambers and Conway’s theoretical perspectives, this study discusses that a community-based model is capable of filling knowledge gaps, not only in scientific research, but also in the community development process of many developing nations, such as Uganda. In this study particularly, a community-based approach has been identified as the better option in aiding and facilitating the current government efforts to transform the agricultural sector from its predominantly subsistence nature to commercial orientation. It has been acknowledged that the Ugandan government and its development partners do realise the significant role agriculture plays in directly or indirectly impacting the social welfare of Ugandans. The agricultural sector has been identified as a major source of livelihood for most rural Ugandans (over 95% depend on it for food, employment and income). Unfortunately, even with such recognition, coupled with many reforms initiated by government and supported by various development partners who have invested huge sums of money into the sector, agricultural productivity and profitability has remained extremely low. Most rural Ugandans still languish in abject poverty, hunger, malnutrition, vulnerability and powerlessness. This study has established that, while the agricultural sector in Uganda suffers from enormous institutional, technological, market, research and land-oriented challenges, if all these factors are kept constant, an effective community-based approach is capable of facilitating effective planning, implementation, management, monitoring, and evaluation of agricultural reforms, for increased agricultural productivity and profitability hence the improved quality of life of Ugandans. A qualitative elicitation interviewing technique involving in-depth discussions with agricultural extension workers, community development officers, representatives from NGOs, local farmers, farmers’ associations, local and religious leaders as well as key persons from the Ministry of Agriculture and other line ministries was conducted. The participants were selected through chain referrals until the level of theoretical saturation. In addition, directed field observations, document analysis and key informant interviews with other respondents selected through theoretical sampling enhanced the robustness of data acquisition methods. Group-based participatory data analysis and reflexive pragmatism also enhanced the rigour and quality of research findings intended to balance the knowledge generated from the recognised scientific audience and the views of the important but unknown “knowledge generators” (the local experts).The key findings indicate that, historically and currently, agriculture has been and is the predominant community development activity at household, community and national levels in Uganda. It is also anticipated that agriculture will remain a major contributor to the national economic development of Uganda even over the next hundred years. The efforts by government and its development partners to transform the sector are therefore justified by the sector’s strategic importance. It has been found out that although the sector faces huge challenges, there are numerous opportunities for the sector to become a driver of Uganda’s socio-economic development. A community-based model has been proposed as a viable option for facilitating faster agricultural development in Uganda, where technocratic developers tend to impose development reforms on local people. With the traditional approaches to planning and implementation, it was thought that local people do not know what they want, they are illiterate and ignorant and therefore incapable of driving government crafted programmes for effective change. From the proposed model, government technocratic development agents should engage local farmers who practically experience poverty, powerlessness, hunger, malnutrition and vulnerability, to jointly craft effective agricultural reforms that are not only life-changing, but also relevant and sustainable within the confines of community needs. Under this approach, the designers, planners, implementers, monitors, and evaluators, whether of government-initiated reforms, or initiatives from other development agencies, should learn to treat local people as subjects of the community development processes, as opposed to the traditional top-down mechanisms which view them as objects to be used and abused. The involvement of local experts during the planning, implementation, and management of development reforms, should cease to be applied as merely routine fulfilment of donor conditionality and requirements. Rather, the participation of local farmers during all phases of community programming should become intentional and consciously aimed at empowering local people to actively participate in the making of decisions critical to their own development.

- Description: The study examined the impact of human capital development on economic growth for 129 countries comprising of developed and developing countries. The primary focus of the study is on examining the contribution of human capital index components on economic growth for the period 2014 to 2017. The panel data model was employed in the study. Firstly, the hausman test was used to determine the suitable method between fixed and random effects. The fixed effects model was selected as the best panel econometric technique to be used in the study. The empirical results showed that there is a positive and statistically significant relationship between human capital index components (capacity, development, deployment and know how) and economic growth. The study also found that these components of human capital index have more impact on economic growth when they are interacted together based on theories of human capital and economic growth. Capacity and development are found to be the best contributors to economic growth for all the regions; thus, the study recommends that for economic growth to be increased, countries should invest more of their funds on capacity and development sub- indexes of human capital index. Exchange rates and inflation are found to have a negative relationship with the economic growth, while interest rates are found to have a positive and statistical relationship with the economic growth. The study also found out that there is a regional effect associated with human capital development, with European region being the best contributor to GDP. The components of human capital index also found to be important for all regions to invest on to improve economic performance. Deployment is found not to be significant is Sub-Saharan Africa. The existence of income group effect is found with developed countries performing much better compared to developing countries. The study also recommended that countries should invest more of their wealth in human capital development components such as education and health to enhance their economic growth
