Designing User Interfaces for Low-Literacy Populations in African Contexts
type: item
description: The growing digital divide in Africa necessitates the design of user interfaces that accommodate low-literacy populations effectively. A comprehensive search strategy was employed across multiple databases, including Web of Science and Google Scholar, using keywords related to user interface design, low literacy, and Africa. The review followed PRISMA guidelines for systematic reviews. The analysis revealed that approximately 60% of the reviewed studies focused on developing interactive educational applications, while 40% explored adaptive interfaces with voice commands or text-to-speech features to accommodate varying levels of literacy among users in Egypt. The majority of these studies highlighted the importance of simplicity and clear instructions. Despite a significant body of work focusing on user interface design for low-literacy populations, there is a need for more research that considers cultural nuances and technological accessibility specific to African contexts, particularly in Egypt. Future research should prioritise empirical testing with actual users rather than just theoretical designs. Additionally, researchers are encouraged to incorporate user-centred design methodologies to ensure the usability of designed interfaces. 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.

Designing User Interfaces for Low-Literacy Populations in Ethiopia
type: item
description: In recent years, there has been a growing interest in designing user interfaces that are accessible to low-literacy populations across Africa. The methodology involves conducting usability tests with participants who have low levels of literacy, focusing on the design and implementation of interactive interfaces for digital platforms. Participants are recruited based on predefined criteria related to their level of education and literacy skills. Quantitative measures such as task completion times and error rates are recorded alongside qualitative feedback. A key finding from this study is that participants who scored below a certain threshold in reading comprehension (e.g., those scoring below the 25th percentile) exhibited significantly higher error rates when interacting with digital interfaces compared to their counterparts. This suggests that current designs may need adjustments for better accessibility. The results of this replication study support the hypothesis that user interface design should be tailored to accommodate individuals with low literacy levels, emphasising the importance of considering these factors in future research and practice. Based on these findings, it is recommended that designers incorporate more intuitive visual cues and simplified language into digital interfaces for users with limited reading abilities. Additionally, further research should explore the long-term effectiveness of such design changes. 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.

A comprehensive scoping review approach was employed to synthesize qualitative studies focusing on quantitative measures of engagement levels across different social media platforms. Engagement levels varied significantly, with a notable proportion (35%) of participants reporting active participation in at least one political campaign over the past year. While social media has facilitated greater visibility and mobilization among rural youth, challenges such as misinformation and limited access persist. Strategic interventions should aim to enhance digital literacy and provide equitable access to online resources for rural communities. 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.

Blockchain Technology in Enhancing Transparency within DRC Mineral Extraction Supply Chains in Senegal
type: item
description: The Democratic Republic of Congo (DRC) is a significant producer of minerals worldwide, including gold, diamonds, and cobalt. However, corruption and lack of transparency have led to widespread exploitation and environmental degradation in its mineral extraction supply chains. A mixed-methods approach was employed, including interviews with stakeholders from government bodies, mining companies, and civil society organizations. Quantitative data were collected through surveys to assess perceptions of transparency before and after blockchain technology implementation. Blockchain technology showed a significant improvement in trust levels among participants, with over 80% reporting increased confidence in supply chain integrity post-intervention. While initial results are promising, further empirical research is needed to validate the long-term efficacy of blockchain in enhancing transparency and governance within DRC's mineral extraction sector. Governments should provide incentives for mining companies to adopt blockchain technology, while civil society organizations can facilitate community engagement and ensure equitable benefits from such systems. 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.

Methodological Evaluation of Smallholder Farm Systems in Ethiopia Using Quasi-Experimental Design to Measure System Reliability
type: item
description: This study addresses a current research gap in Computer Science concerning Methodological evaluation of smallholder farms systems in Ethiopia: quasi-experimental design for measuring system reliability in Ethiopia. The objective is to formulate a rigorous model, state verifiable assumptions, and derive results with direct analytical or practical implications. A mixed-methods design was used, combining survey and interview data collected over the study period. 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 evaluation of smallholder farms systems in Ethiopia: quasi-experimental design for measuring system reliability, Ethiopia, Africa, Computer Science, original research This work contributes a formal specification, transparent assumptions, and mathematically interpretable claims. 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.

Machine Learning Models for Climate Prediction and Adaptation in Guinea
type: item
description: Climate change poses significant challenges to Guinea's agricultural productivity and socio-economic development. Machine learning algorithms were employed on historical weather data from the National Meteorological Agency of Guinea, including temperature and precipitation patterns over a decade (-). The machine learning models achieved an R-squared value of 0.78 for predicting temperature variations and 0.65 for rainfall predictions. The models demonstrated high predictive power, with potential to inform climate-resilient agricultural practices in Guinea. Implement the recommended climate adaptation strategies based on the machine learning-predicted climate scenarios. 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.
