A mixed-method approach including surveys and observational data collection was employed. Statistical analysis utilised regression models to assess the effects of network features on adoption rates. The regional monitoring networks showed an adoption rate of approximately 35% across all monitored areas, with higher uptake in urban centers compared to rural regions. The quasi-experimental design provided robust insights into factors influencing ICT adoption, offering a comprehensive understanding of current challenges and potential solutions. Further research should focus on developing tailored strategies for different educational contexts within Ghana based on the findings. 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.

Leveraging Mobile Technologies for Agricultural Knowledge Dissemination in Senegal
type: item
description: Mobile technologies have become increasingly prevalent in Senegal's agricultural sector, offering a means to disseminate knowledge and information more efficiently. The study employed mixed-methods research, including quantitative surveys and qualitative interviews with a sample of 150 farmers across three regions in Senegal. Data analysis utilised descriptive statistics and thematic coding to identify patterns and themes related to technology usage and outcomes. Findings indicated that the use of mobile applications significantly improved farmers' knowledge about agricultural practices, leading to an increase of 20% in crop yields among participants who used these tools regularly. The study concludes that mobile technologies can effectively enhance agricultural information dissemination and positively influence farmers' productivity, particularly when tailored to local contexts. Based on the findings, it is recommended that policymakers invest more in developing and promoting mobile applications designed specifically for Senegalese agriculture, alongside ongoing training programmes for users. 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.

Open Data Initiatives and Governance Transparency in Djibouti
type: item
description: Open data initiatives have gained traction as a means to enhance transparency in governance and foster informed decision-making. Djibouti has initiated several open data projects aimed at improving public services, but their effectiveness remains under scrutiny. A mixed-methods approach combining quantitative analysis of public sector performance metrics with qualitative interviews among government officials and civil society organizations (CSOs). Analysis reveals a positive correlation between the number of open data releases and improvements in service delivery efficiency, though these effects are not uniform across all sectors. While Djibouti's open data initiatives show promise, they require more robust governance frameworks to ensure equitable access and meaningful utilization by stakeholders. The government should establish clear guidelines for data quality assurance and expand outreach efforts to engage a wider audience of users.
