Abstract

fetched live from OpenAlex

Ashley Smith, who is typically presented in the media as mentally ill, was nineteen years old when she died from self-strangulation in an Ontario women's prison on October 19 th , 2007.In this thesis, I explored how Ashley Smith's actions and death were portrayed in four mainstream Canadian newspapers (Globe and Mail, Telegraph-Journal, Toronto Star and National Post).My aim in this thesis is to critically analyze patterns of stereotypes of mental illness present in these news articles and connect these patterns to labeling theories.To accomplish this goal, I used a mixed methods approach that combined computerized topic modeling with critical reading.Topic modeling revealed three variables that affected topic weight: the timing of the news coverage, newspaper political affiliation and circulation/location.These three variables also impacted how these newspapers depicted Ashley Smith as mentally ill, through their use of generic and/or negative terminology, medicalization and vulnerability stereotypes.iii Dedication This thesis is dedicated to the memory of Pat Seguin.A fierce feminist advocate and friend who encouraged me to return to academics and constantly reminded me to never give up without a fight.I would like to take the opportunity to express my deep gratitude to several people for their support during the process of completing this thesis.First, I would like to thank my partner and topic modeling research

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.
