Securing The Flow: Strategic Storage And Corridor Design For Maritime Energy Security Under Chokepoint Disruptions, Monit Sharma, Hoong Chuin Lau Jan 2026

Securing The Flow: Strategic Storage And Corridor Design For Maritime Energy Security Under Chokepoint Disruptions, Monit Sharma, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

Maritime disruption planning requires joint strategic storage and transport capacity decisions under uncertainty. We develop a two-stage stochastic multi-commodity network-design model for national energy security that integrates corridor commitments, port--commodity inventories, storage expansion, and scenario-dependent routing for crude oil, LNG, LPG, and fertilizer. The formulation incorporates decision-dependent probabilities, corridor concentration limits, and mean--CVaR risk, admitting an exact MILP reformulation. In a data-anchored India-inspired case study, stochastic modeling outperforms the expected-value policy by 1.35%, with decision-dependent probabilities worth 0.67%. Service levels are heterogeneous: crude and fertilizer maintain full coverage, while LNG and LPG drop to 34.6% and 33.3% under worst-case scenarios. …

Navigating School Re-Entry For Teen Mothers In Arua District, Uganda, Flavia Mane Eriku, Mweru Mwingi

Institute for Educational Development, East Africa

Uganda's 2020 Education Re-entry Policy supports teenage mothers to resume schooling after pregnancy, yet re-enrollment remains low. In a qualitative case study in two public secondary schools in Arua District, we identified key barriers to be inadequate guidance, stigma, discrimination, irregular attendance, limited knowledge and resources, and forced marriage. We recommend boosting teen mothers’ self-esteem through personalized counseling, mental health support, and community awareness of the value of education. Strengthening these areas can enhance policy implementation and help policymakers and practitioners improve monitoring and educational reintegration for teenage mothers.
