Spatio-Temporal Modeling of Land-Use/Land-Cover Change and Land Surface Temperature Using SVM and CA-Markov in Dilla Town, Ethiopia. [PDF]

Glob Chall
Multi‐temporal Landsat imagery (2001, 2011, 2021) was used to map land use/land cover and retrieve land surface temperature, quantify change, and model future scenarios. Results indicate rapid expansion of built‐up land accompanied by declining mixed forest and cropland and increasing thermal hotspots.

Optimizing Measurement of Communication in Autistic Children and Their Caregivers: Dependability of the Caregiver-Child Interaction. [PDF]

Autism Res
ABSTRACT Despite widespread use of caregiver‐child interactions (CCX) to evaluate outcomes in autism interventions, little research has examined the dependability of this measure. This study applied generalizability theory to determine optimal conditions for dependable assessment of child communication and caregiver implementation of communication ...
