2 - Enhancing Doctoral Supervision Practices in Africa: Reflection on the CARTA Approach
Bibliographic record
Abstract
High quality research supervision is crucial for PhD training, yet it continues to pose challenges globally with important contextual factors impacting the quality of supervision. This article reports on responses to these challenges by a multi-institutional sub-Saharan Africa initiative (CARTA) at institutional, faculty and PhD fellow levels. The article describes the pedagogical approaches and structural mechanisms used to enhance supervision among supervisors of CARTA fellows. These include residential training for supervisors, and supervision contracts between primary supervisors and PhD fellows. The authors reflect on the processes and experiences of improving PhD supervision, and suggest research questions that CARTA and other training programmes could pursue in relation to PhD supervision in Africa and other lower- and middle-income countries.

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.
