The complexity of neighborhood effects: A developmental and ecological framework for violent victimization

open access: yesCriminology, EarlyView.
Abstract Extensive research has established a link between low self‐control and child victimization. However, the specific neighborhood conditions under which low self‐control most strongly influences victimization have been little examined, and, more importantly, no previous studies have investigated the complex ways in which neighborhood context ...

Comparing verbenone‐based repellents for ambrosia beetle management in eastern apple orchards

open access: yesAgricultural and Forest Entomology, EarlyView.
Non‐native ambrosia beetles (Xylosandrus germanus, X. crassiusculus, Anisandrus maiche) damage high‐density apple orchards across the eastern United States, motivating the search for selective, semiochemical‐based repellent strategies. Across Ohio, New York and Pennsylvania, three verbenone formulations, sachets, SPLAT® VERB and a test SPLAT ...
