Earthquake loss estimates in near real‐time [PDF]

open access: yesEos, Transactions American Geophysical Union, 2006
The usefulness to rescue teams of nearreal‐time loss estimates after major earthquakes is advancing rapidly.The difference in the quality of data available in highly developed compared with developing countries dictates that different approaches be used to maximize mitigation efforts. In developed countries, extensive information from tax and insurance

Comparing Discounting of Potentially Real Rewards and Losses by Means of Functional Magnetic Resonance Imaging

open access: yesFrontiers in Systems Neuroscience, 2022
AimDelay discounting (DD) has often been investigated in the context of decision making whereby individuals attribute decreasing value to rewards in the distant future. Less is known about DD in the context of negative consequences. The aim of this pilot
