A Novel Multilevel Conceptual Framework for Flood Risk Governance

Environmental Policy and Governance, EarlyView.
ABSTRACT Globally, flood risk is increasing as climate change progresses. Contemporary flood risk management practice often utilises hydrodynamic modelling (for hazard risk assessments), social vulnerability assessments, and risk communications in silo, which fragments evidence‐based decision‐making for effective flood risk management. We hence develop

Self‐Powered Diamond Homojunction Photodetectors for Stable Ultraviolet Sensing Under High Temperatures

Electron, EarlyView.
In this work, we report an unintentionally doped/boron‐doped diamond homojunction ultraviolet photodetector grown by microwave plasma chemical vapor deposition. The device achieves self‐powered ultraviolet detection with negligible performance degradation even at temperatures of up to 250°C.

Digital Rights Activism in Multilevel Governance

European Policy Analysis, EarlyView.
ABSTRACT Multilevel governance (MLG) without a clear hierarchical structure can create power imbalances among various actors, particularly in settings with overlapping jurisdictions and policy areas. This dynamic is especially pronounced in Internet governance, which faces a complex interplay of domestic laws, state interdependence, and heightened ...
