The aim of this paper is to construct a time-varying estimator of the investors' risk aversion function. Jackwerth (1996) and Aït-Sahalia and Lo (1998) show that there exists a theoretical relationship between the Risk Neutral Density (RND), the Subjective Density (SD), and the Risk Aversion Function. The RND is estimated from options prices and the SD is estimated from underlying asset time se...

DEAR LADIES AND GENTLEMEN OF THE American Science Community: As I write this from my troubled home state of Kansas, the State Board of Education is debating once again whether to de-emphasize the theory of evolution. Those in the majority on the Board have stated that they are considering changing the very definition of science to allow for science classes to discuss the merits of intelligent d...

Illustrated descriptions of the larvae of the water mite species of Lebertia longiseta Bader, 1955, Oxus nodigerus Koenike, 1898 and redescription of the larva L. dubia (Thor, 1899) are presented.

Normal aging is typically characterized by abnormal resting-state functional connectivity (FC), including decreasing connectivity within networks and increasing connectivity between networks, under the assumption that the FC over the scan time was stationary. In fact, the resting-state FC has been shown in recent years to vary over time even within minutes, thus showing the great potential of i...

I review the ways that have been proposed to measure the quark transversity distribution in the nucleon. I then explain a proposal, developed by Xuemin Jin, Jian Tang and myself, to measure transversity through the final state interaction between two mesons (ππ, KK, or πK) produced in the current fragmentation region in deep inelastic scattering on a transversely polarized nucleon.
