Understanding the causes of urban fragmentation in Hanoi: the case of new urban areas
Bibliographic record
Abstract
Since the late 1990s, a new model of urban development has been promoted in Vietnam. So-called 'new urban areas' are being built on the agricultural lands at the periurban interface of cities across the country. These large-scale redevelopments feature commodity housing and public services, along with commercial and office space. Foreign scholars have criticised the lack of integration between these built environments and existing urban agglomerations. The resulting urban fragmentation is commonly blamed on the imposition of a foreign model of urban development that promotes a break with previous urban space production mechanisms. This paper provides a nuanced view on these ideas by exploring the history of housing policy in Vietnam and in the region of Hanoi in particular. This approach underscores the locally situated nature of the new urban area experiments. At the same time, it reveals the need to explore ongoing shifts in the way various groups straddling the state, markets and society interact in contemporary urban space production processes.

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.
