Playing Under Pressure: Lived Meanings, Tensions, and Re-Significations in Teachers’ Ludic Mediation Through Play and Toys

Play and toys are central resources for learning; however, their integration into schooling is typically traversed by curricular, evaluative, disciplinary, and institutional tensions, particularly in resource-limited contexts. This study examined the meanings, tensions, and re-si...

Comparative Evaluation of Machine Learning Models for Global Horizontal Irradiance Estimation in an Arid Coastal Climate

Accurate estimation of global horizontal irradiance (GHI) is relevant for characterizing solar resources in regions with limited measurement infrastructure. This study compared six machine learning models Polynomial Ridge Regression, Decision Tree, Random Forest, XGBoost, Artific...

Real-World Emission Factors for Andean Light-Duty Vehicles Based on a PSVm10-Validated Driving Cycle Across 0–4000 m Altitude

Emission inventories for high-altitude Andean cities rely on sea-level certification cycles that misrepresent real-world combustion conditions. This study derives altitude-resolved emission factors (EFs) for light-duty gasoline vehicles across 0–4000 m a.s.l. in Ecuador using the...
