Ali K., Olfert M. R. and Partridge M. D. Urban footprints in rural Canada: employment spillovers by city size, Regional Studies. Growing rural-to-urban commuting epitomizes a de facto regionalization process that is unique for each urban area and its spatial setting. In evaluating these relationships, commuting patterns for 115 Canadian urban areas are estimated empirically. A novel weighted-averaging process reveals a rich spatial pattern that illustrates significant heterogeneity attributable to differences in urban size and to geographical diversity. Strong distance attenuation effects exhibit non-trivial variations in their intensity and geographic reach across the country. The general patterns are consistent with urban hierarchy notions of functional regions that both compete with and overlap one another. Governance and infrastructure planning would benefit from understanding these interdependencies.Ali K., Olfert M. R. et Partridge M. D. Les traces urbaines en milieu rural au Canada: des excédents d'emplois par taille des grandes villes, Regional Studies. La croissance des migrations ruralo-urbaines quotidiennes incarnent de facto un processus de régionalisation qui est unique à chaque zone urbaine et à son cadre géographique. Pour évaluer ces rapports, on estime empiriquement les migrations quotidiennes pour 115 zones urbaines au Canada. Un processus original de moyennes pondérées laisse voir une riche distribution géographique qui illustre une importante hétérogénéité imputable aux différences de la taille urbaine et de la diversité géographique. D'importants effets de modération quant à la distance laissent voir des variations non-négligeables de leur intensité et de leur portée géographique à travers le pays. Les distributions générales conforment à des notions hiérarchiques urbaines de régions fonctionnelles qui se font la concurrence et se chevauchent. Une meilleure compréhension de ces interdépendances serait au profit de la gouvernance et de la planification de l'infrastructure.Migrations quotidiennes Régionalisation Marchés du travail régionauxAli K., Olfert M. R. et Partridge M. D. Urbane Fußabdrücke in ländlichen Gebieten Kanadas: Übertragung von Beschäftigung je nach Stadtgröße, Regional Studies. Ein wachsender Pendlerverkehr von ländlichen in städtische Gebiete ist der Inbegriff eines De-facto-Regionalisierungsprozesses, der für jedes städtische Gebiet und seine räumliche Umgebung einzigartig ist. Zur Bewertung dieser Beziehungen wurden die Pendlerströme von 115 Stadtgebieten Kanadas empirisch geschätzt. Ein neuartiges Verfahren zur Ermittlung des gewichteten Durchschnitts führt zu einem erweiterten räumlichen Muster, das eine signifikante Heterogenität verdeutlicht, die durch Unterschiede hinsichtlich der Größe und geografischen Diversität der Städte verursacht wird. Starke entfernungsbedingte Abschwächungseffekte führen landesweit zu nicht vernachlässigbaren Variationen hinsichtlich der Intensität und geografischen Reichweite. Die generellen Muster stimmen mit der Auffassung von der urbanen Hierarchie funktionaler Regionen überein, die miteinander konkurrieren und sich zugleich überschneiden. Die Planung von Politik und Infrastruktur würde von einem Verständnis dieser Wechselwirkungen profitieren.Pendlerverkehr Regionalisierung Regionale ArbeitsmärkteAli K., Olfert M. R. y Partridge M. D. Huellas urbanas en las zonas rurales de Canadá: desbordamientos de empleo según el tamaño de las ciudades, Regional Studies. El creciente proceso de desplazamientos al trabajo de un área rural a otra urbana epitomiza un proceso de regionalización de facto que es único para cada área urbana y su entorno espacial. Al evaluar estas relaciones, se calculan empíricamente los modelos de desplazamientos en 115 áreas urbanas de Canadá. Un nuevo proceso de promedios ponderados indica un amplio modelo espacial que ilustra una heterogeneidad significativa atribuible a las diferencias en el tamaño urbano y la diversidad geográfica. Los fuertes efectos de atenuación de las distancias muestran variaciones no triviales en su intensidad y alcance geográfico en todo el país. Los modelos generales son coherentes con las nociones de jerarquías urbanas de las regiones funcionales que compiten y se solapan entre ellas. La gobernanza y la planificación de infraestructura se beneficiaría si fuese capaz de entender estas interdependencias.Desplazamietos al trabajo Regionalización Mercados laborales regionales

Not 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.
