Abstract

fetched live from OpenAlex

Transport contributes around 11% of greenhouse gas emissions and the sector is also vulnerable to climate change. High temperatures can melt roads and distort rail lines while sea-level rise can disrupt coastal transport infrasructure. At the community level, cities and precincts can help mitigate climate change and adapt to changes by promoting active lifestyles with walking and bicyling replacing powered transport for short-distance travel and making cities more compact. Significant cost and health benefits can accrue from reduction of diseases associated with low physical activity and air pollution can also be mitigated. Increased provision and electrification of public transport based on renewable energy can decarbonise these services. The electification of sea and air transport present challenges but significant development work is underway with expected early availability of electrically powered short-haul aircraft. Phase-out of internal combustion engine cars and other vehicles is scheduled in several countries as battery-electric and hydrogen cars, buses and heavy transport vehicles emerge. Governments can help the transition with a range of policy initiatives.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
