Abstract

fetched live from OpenAlex

In this paper, a Stated Preference (SP) analysis was carried out to identify the factors that influence people to choose highway assistance services (FSP) over private assistance services (PAS). The Los-Angeles FSP was used as a test case and the B/C ratios were also calculated based on the utility the FSP provides to an individual. Different values were chosen for the average time of waiting of the FSP and the B/C ratios were calculated in each case. The results indicate that the probability of an individual choosing the highway assistance services depends on the attributes of the program like the time of waiting for assistance and cost of waiting for assistance. The B/C ratios for the Los Angeles FSP were in the range 6.2-6.3.

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.
