Talking to Twitter users: Motivations behind Twitter use on the Alberta oil sands and the Northern Gateway Pipeline
Bibliographic record
Abstract
Environmental issues are being discussed through social media with increased frequency. Researchers are starting to question whether social media demonstrates a green virtual sphere: a virtual public space to discuss environmental issues that is not governed by a single authority and that anyone can access. We investigate why people use Twitter to communicate about two Canadian-based environmental issues using interviews with 10 highly engaged users. We found that they used Twitter to access news and engage in debates; however, they also raised a number of concerns: the potential for overestimating the impact of their own and others’ online activities; the prospect of harassment from other users; and the possibility of being labelled an extremist. Given these findings, we conclude that in this case, Twitter only partially demonstrates the characteristics of a green virtual sphere because it increased access to information and provided a space for debate but access to the space was not equal and users were aware that discussions were likely being monitored.
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.

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.
