Three years after a disaster : the impacts of a derailed train on the behavior and health of High School students
Bibliographic record
Abstract
In July 2013, a train derailed in downtown Lac-Mégantic, Quebec. It was responsible for forty-seven deaths, forty-four buildings destroyed, 2000 evacuees, and a major oil spill. A survey has been conducted during winter 2017 among high school students to examine their psychological and social characteristics and the impact of this disaster in regards of exposure or no exposure to this event. The results show that the majority of the respondents are satisfied with their school, their family, and their social life. They have good self-esteem. Many traumatized students thought about suicide in the twelve months prior to the survey. They also report more self-injurious thoughts than non-exposed students. They also showed more moderate to severe post-traumatic stress disorders (scores of twnety-six or more at the Impact of Event Scale). Exposed students were also significantly more likely than non-exposed students to report a deterioration in the quality of life within their municipality.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
