This study examines cognitive reserve theory by investigating the relationship between education and cognitive performance across developed and developing countries. Using numeracy and verbal fluency measures, it finds that higher education consistently improves cognition. However, cognitive performance is largely similar across countries once education level is considered, challenging assumptions about educational quality differences.

This research examines how vulnerable communities can finance renewable energy transitions without relying on fossil fuel industries. By analyzing international climate finance agreements, it proposes fairer, more accessible funding structures that empower marginalized regions—such as the Niger Delta—to pursue clean energy while addressing climate justice and inequality.
