Systems of practice and the Circular Economy: Transforming mobile phone product service systems
Bibliographic record
Abstract
Of late, policy and research attention has increasingly focused on making the Circular Economy a reality. A key part of this agenda is the creation of Sustainable Product Service Systems (SPSS) that meet consumers’ needs whilst lessening negative environmental impacts. Although the SPSS literature has grown recently, key aspects require further examination. In response, this paper discusses empirical research exploring consumers’ reactions to a novel, hypothetical mobile phone SPSS, utilizing qualitative methods that included ‘business origami’. It examines consumers’ knowledge about current mobile phone life cycles, and responses to the proposed SPSS, drawing on a ‘systems of practice’ framework to discuss the potential for significant changes in phone purchase and use. It outlines barriers to alterations in practices, underscoring the centrality that connectivity and data storage now have in many peoples’ daily lives, which have for some become clustered around the capabilities and accessibility of the mobile phone.

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.
