Disruption risks to global container shipping network in the presence of COVID-19 pandemic: a static structure and dynamic propagation perspective
Bibliographic record
Abstract
This study examines the disruption risks of the global container shipping network from a static structure and dynamic propagation perspective. First, the topological structure of the global container shipping network is investigated by constructing a weighted and directed network. Second, the hidden risks are uncovered by the proposed disruption risk propagation model in the global container shipping network. The results indicate that the global container shipping network is characterised by 'hub and spoke' feature with a 'robust yet fragile' structure. Ports in Asia play an essential role in the global container shipping network. Additionally, risky outbound ports are located in China, and risky inbound ports are located in India and Canada. The hidden shipping route risks are focused on China and Singapore, South Korea. Finally, the propagation speed of port inbound disruption is faster than that of port outbound disruption.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
