Ambulant vendors’ living labour on Copacabana beach
Bibliographic record
Abstract
Abstract This article uses video-ethnography to offer the first examination of the working practices of ambulant vendors on Copacabana Beach in actual time. It focuses on how these workers enact agency as they navigate the limiting physical and social boundaries of the beach to earn a living. It does this by adopting the notion of “bounding” and drawing on the metaphor of the fresta (“interstice”). The analysis unveils the assemblage of communicative resources vendors deploy in real-time to maximise their presence to beachgoers and minimise the risk of detection by authorities. It shows how successive and simultaneous modalities (mobile, visual, verbal) reinforce each other’s capabilities according to the spatiotemporal juncture of vendors’ bounding activity. The article expands our understanding of how language as an agentic multimodal tool is used to challenge systemic inequalities.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
