Structuring wicked problems in science communication
Review of Policy Research, EarlyView.Abstract Public policy scholars increasingly deal with wicked problems and how diverse actors structure these problems in policy processes. However, the role of actors at the interface of science and society such as science communicators in structuring wicked problems remains widely unclear.

Using porous metals to enhance heat transfer in phase change materials (PCMs) [PDF]
, 2011 Heat transfer enhancement mechanism of Phase Change Materials (PCMs) by high-porosity metal foams was investigated in this study. The Darcy-Brinkman-Forchheimer modified flow model was employed in the numerical simulations to consider the non-Darcy ...

Review of Policy Research, EarlyView.Abstract Short‐term policy (STP) has attracted considerable attention as a form of time‐related public policy and is typically used to solve urgent problems. The objective of this study, which considers STP as policy myopia from an information science perspective, is to discuss the challenges encountered during the STP policymaking process and their ...

Veterinary Dermatology, EarlyView.Background – Recurrent urticaria is common in horses. The pathophysiology is poorly understood and treatment options are limited. Often only glucocorticoids are effective for controlling clinical signs, albeit with potential adverse effects. Studies investigating new treatments need a validated objective scoring system for the grading of skin lesions ...
