Criminology, EarlyView.Abstract To mitigate the consequences of school punishment, we must move from documenting the school‐to‐prison pipeline (STPP) toward understanding how punishment increases criminal legal system involvement. Beyond impacting academic performance, punishment may encourage disengagement from school, teachers, and peers; delinquency; and secondary ...

Seasonal Habitat Selection by a Threatened Ungulate in an Industrializing Boreal Landscape
Animal Conservation, EarlyView.Understanding habitat selection by Threatened wood bison in landscapes characterized by anthropogenic disturbance is important for conservation planning. During summer and winter, bison selected for linear (e.g., roads, seismic lines, pipelines) and polygonal (e.g., well sites) disturbances, unless there were high densities of linear features.
