Computer Simulation of the Electrical Stimulation of the Human Vestibular System: Effects of the Reactive Component of Impedance on Voltage Waveform and Nerve Selectivity.

The vestibular system is responsible for our sense of balance and spatial orientation. Recent studies have shown the possibility of partially restoring the function of this system using vestibular implants. Electrical modeling is a valuable tool in assisting the development of these implants by analyzing stimulation effects.

Intuition and Deliberation in the Stag Hunt Game.

We present an incentivized laboratory experiment where a random sample of individuals playing a series of stag hunt games are forced to make their choices under time constraints, while the rest of the players have no time limits to decide. We find that individuals under the time pressure treatment are more likely to play stag (vs. hare) than individuals in the control group: under time constraints 62.

Improved Repeatability of the Estimation of Pulsatility of Inferior Vena Cava.

The inferior vena cava (IVC) shows variations of cross section over time (pulsatility) induced by different stimulations (e.g., breathing and heartbeats).

Modernization, weather variability, and vulnerability to famine.

This paper shows that under weather variability the transformation from a rural to an incomplete market economy can increase the vulnerability of peasants to famine. This can occur even if improvements in technology have raised agricultural productivity and made production less responsive to weather variability. Indeed, negative environmental shocks can produce a drop in wages that outweighs the increase in wages due to an equivalent positive environmental shock.
