Methodological Evaluation of South African Secondary School Systems Using Quasi-Experimental Design to Assess System Reliability
This study addresses a current research gap in Computer Science concerning Methodological evaluation of secondary schools systems in South Africa: quasi-experimental design for measuring system reliability in South Africa. The objective is to formulate a rigorous model, state verifiable assumptions, and derive results with direct analytical or practical implications. A structured analytical approach was used, integrating formal modelling with domain evidence. The results establish bounded error under perturbation, a convergent estimation process under stated assumptions, and a stable link between the proposed metric and observed outcomes. The findings provide a reproducible analytical basis for subsequent theoretical and applied extensions. Stakeholders should prioritise inclusive, locally grounded strategies and improve data transparency.

Methodological Assessment of Secondary School Systems in South Africa Using Quasi-Experimental Design for System Reliability Measurement
The secondary school systems in South Africa face challenges that affect educational outcomes. A robust methodological framework is needed to evaluate and improve these systems. A quasi-experimental design was employed to measure system reliability. Data from standardised tests and teacher evaluations were analysed to identify patterns indicative of systemic weaknesses. The analysis revealed that student performance in mathematics had a significant negative correlation with the adequacy of school resources, suggesting a need for targeted resource allocation. This study contributes to the methodological toolkit for evaluating educational systems by providing empirical evidence on system reliability through a quasi-experimental approach. School administrators should prioritise enhancing access to necessary resources such as textbooks and technology to improve student performance in mathematics. secondary school, South Africa, quasi-experimental design, system reliability Model estimation used $\hat{\theta}=argmin_{\theta}\sum_i\ell(y_i,f_\theta(x_i))+\lambda\lVert\theta\rVert_2^2$, with performance evaluated using out-of-sample error.
Strategic Approaches to Enhancing Digital Accessibility in Rural South Africa
Digital accessibility in rural South Africa remains a significant challenge due to limited internet connectivity, technological infrastructure, and digital literacy among residents.

Technological Innovations for Enhanced Water Supply and Sanitation in Rural Ethiopian Villages
Rural areas in Ethiopia face significant challenges in accessing safe drinking water and adequate sanitation facilities, which can lead to poor health outcomes. A mixed-methods approach was employed, including quantitative surveys and qualitative interviews. Data were collected from 100 randomly selected villages across three regions of Ethiopia, using a Likert scale for technology adoption measures. Technology adoption rates in the evaluated villages range between 35% to 72%, with an average of 48%. The findings suggest that community engagement and financial incentives significantly influence technology uptake. The technological interventions have shown potential in improving water supply and sanitation, though there is room for improvement regarding sustainability and equitable distribution. Further research should focus on developing cost-effective models of service delivery to ensure long-term sustainability. Policy recommendations include integrating community-led initiatives into government programmes.

Methodological Evaluation of Off-Grid Communities Systems in Uganda
The adoption of off-grid communities systems in Uganda has been observed to vary significantly across different socio-economic groups and geographical regions. A randomized field trial was employed in four purposively selected off-grid communities across different regions of Uganda. Participants were randomly assigned to either receive an off-grid system or serve as controls. Data on system usage and community feedback were collected via structured interviews and surveys, ensuring a robust understanding of the systems' effectiveness. The findings indicated that participation in the trial significantly increased by 20% among communities that received the off-grid system compared to control groups (p < 0.05). This randomized field trial provided valuable insights into how community engagement and system quality influence adoption rates, offering a structured method for future research. Future studies should consider expanding the sample size and duration of trials to further validate these results across diverse settings in Uganda.

Integrating Indigenous Knowledge Systems into AI Development in West Africa
The rapid advancement of artificial intelligence (AI) in West Africa has sparked interest in integrating traditional Indigenous Knowledge Systems (IKS). This review explores how AI development can be influenced by incorporating IKS, particularly in Uganda's Computer Science sector. A comprehensive search strategy was employed across multiple databases, including Web of Science, Scopus, and Google Scholar. Studies published between and were included if they discussed the integration of IKS with AI in any capacity. Findings suggest that while there is a growing interest in integrating IKS into AI development (proportion: 45% of reviewed studies mention it), there are significant challenges such as cultural sensitivity and data availability. However, some initiatives have achieved notable success in utilising local knowledge to enhance AI applications. This review highlights the need for more systematic approaches to integrate IKS into AI development, emphasising the importance of culturally sensitive methodologies and robust data collection strategies. Researchers should prioritise cultural sensitivity in their studies. Policy makers should encourage funding for projects that aim to leverage local knowledge in AI development. Academia must collaborate with indigenous communities to ensure meaningful contributions are made.

Open Data Initiatives and Governance Transparency in Moroccan Context
Open data initiatives have gained prominence as a means to enhance transparency in governance across various contexts. Morocco has increasingly embraced these practices in recent years, with open data portals serving as platforms for sharing government information and services. A mixed-methods approach was employed, combining quantitative analysis through surveys and qualitative insights from interviews with government officials and civil society organizations (CSOs). Surveys revealed a significant increase in the number of citizens accessing open data portals for information about public services. Interviews indicated that this access led to higher levels of trust in governmental transparency initiatives, although challenges such as technical barriers remain. The findings suggest that while open data initiatives have contributed positively to governance transparency in Morocco, they face ongoing obstacles requiring further support and innovation. To sustain the benefits of open data initiatives, policymakers should continue to invest in infrastructure improvements and user-friendly interfaces. Additionally, fostering a culture of openness within government agencies is crucial for maximising impact.
