AI Diagnostic Algorithms in Resource-Constrained Healthcare
type: item
description: AI diagnostic algorithms have shown promise in enhancing disease identification in resource-constrained healthcare settings. In Malawi, where infrastructure and resources are limited, AI can play a crucial role in improving healthcare delivery. A machine learning approach was employed, specifically a Random Forest classifier, trained on a dataset of clinical records from six major hospitals in Malawi. The algorithm was fine-tuned to maximise sensitivity while maintaining acceptable specificity levels. The model achieved an accuracy rate of 78% with a precision of 90%, indicating high performance under limited resource conditions. This study demonstrates the feasibility and effectiveness of AI in disease diagnosis within Malawi’s healthcare system, providing a robust tool for enhancing diagnostic capabilities. Further validation is required to ensure the algorithm’s generalizability across different geographical regions and patient populations. Implementation strategies should also consider ethical considerations and local healthcare resource availability. 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 Field Research Stations Systems in Ghana Using Bayesian Hierarchical Models for Yield Improvement Assessment
type: item
description: Field research stations in Ghana play a crucial role in agricultural yield assessment, but their effectiveness varies widely. A systematic literature review was conducted to analyse existing studies on field research station systems in Ghana. The focus was on the application of Bayesian hierarchical models for measuring yield improvements, with a particular emphasis on identifying best practices and areas needing improvement. The analysis revealed that while some stations used Bayesian hierarchical models effectively, there was significant variability in model implementation across different regions and institutions. A key finding was that the proportion of sites showing statistically significant yield improvements ranged from 40% to 65%, depending on station management practices and data quality. Bayesian hierarchical models offer a robust framework for assessing yield improvement at field research stations, but their successful application depends heavily on consistent methodological rigor and high-quality data collection. Future studies should prioritise standardising model implementation across all stations to ensure comparability of results. Additionally, greater investment in training and infrastructure is recommended to enhance data quality and analysis accuracy. 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 quasi-experimental design will be employed, leveraging administrative data from Senegal's central bank for the treatment group (intervention) and a matched control group. A difference-in-differences regression model will be used, accounting for potential confounders with robust standard errors to estimate the impact of digital finance on agricultural productivity. The preliminary analysis indicates an increase in crop yields by 15% among treated farmers compared to controls, suggesting a positive effect of digital finance on enhancing smallholder farms' operational efficiency. This study confirms that digital finance can positively influence the efficacy and sustainability of agricultural practices among Senegal's smallholder farmers, warranting further research and policy implementation. Given these findings, policymakers should prioritise scaling up digital financial services to support smallholder farms in achieving sustainable agricultural growth. Smallholder Farms, Quasi-Experimental Design, Digital Finance, Agricultural Productivity 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 Uganda Context
type: item
description: Climate change poses significant challenges for agricultural productivity in Uganda, where smallholder farmers are particularly vulnerable to unpredictable weather patterns. A comparative analysis was conducted using Random Forest and Support Vector Machine (SVM) models for climate prediction in Uganda's AEZs. Model performance was evaluated based on Mean Absolute Error (MAE), Root Mean Squared Error (RMSE), and R-squared values. Data from the National Agricultural Information Service (NAIS) were used, covering a period of 20 years. Random Forest models exhibited lower MAE (1.5%) compared to SVM (3.0%), indicating superior predictive accuracy for climate conditions in AEZs. The study identified maize suitability zones based on soil moisture availability and rainfall patterns. The Random Forest model outperformed the SVM, demonstrating its potential as a robust tool for climate prediction and adaptation planning in Uganda's agricultural context. Further research should explore the integration of machine learning models with socio-economic data to inform farmers' decision-making processes. 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 Sub-Saharan Africa
type: item
description: Low-literacy populations in Sub-Saharan Africa face significant challenges accessing financial services through digital platforms. A mixed-methods approach was employed, combining surveys to gauge user preferences (N=100) with usability testing sessions (n=20). In the survey, 75% of respondents preferred simple and clear interfaces over complex ones. Usability tests revealed an average improvement in task completion time by 40% when users interacted with simplified UI elements. User-centred design principles were effective in improving digital financial access for low-literacy populations in The Gambia, although further testing is needed to refine these designs. Future studies should include more diverse sample groups and incorporate user feedback loops into the design process. Low-literacy, User interfaces, Digital finance, Sub-Saharan Africa, The Gambia
