The soft channels of policy diffusion: Insights from local climate change adaptation policy
Policy Studies Journal, Volume 52, Issue 4, Page 881-906, November 2024.Abstract Diffusion has become both an important concept for studying policy spread and a popular governance approach, particularly where direct coercion is unavailable or undesirable. However, the prevailing mechanism‐centered concept is difficult to measure and poorly captures the governance potential of policy diffusion. To address these issues, this

Reframing wildlife disease management problems with decision analysis
Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Contemporary wildlife disease management is complex because managers need to respond to a wide range of stakeholders, multiple uncertainties, and difficult trade‐offs that characterize the interconnected challenges of today. Despite general acknowledgment of these complexities, managing wildlife disease tends to be framed as a scientific ...
