Aging, Probability Weighting, and Reference Point Adoption: An Experimental Study

We examine generational differences in risk-taking behavior by means of a laboratory experiment with monetary incentives. We estimate the parameterized models in the framework of cumulative prospect theory and examine the risk aversion, probability weightings and reference point adoption of elderly and young groups. The results of our experiment indicate that the elderly group is less sensitive to changes in probability and tends to underestimate large probabilities and overestimate small probabilities more strongly than does the young group. Furthermore, we find that the elderly update their reference point after gains and tend to derive their utility from gains and losses not from levels of wealth. In sum, we find that the elderly group's behavior departs more from the traditional expected utility theory than does the young group's behavior.

An Abelian effective action reproducing screening and confinement in quenched SU(2) QCD

In an Abelian projection SU(2) gluodynamics contains Abelian gauge fields (diagonal degrees of freedom) and Abelian matter fields (off-diagonal degrees). The matter fields are essential for the breaking of the adjoint string. We obtain numerically the effective action of the Abelian fields in quenched SU(2) QCD and show that the Abelian matter fields provide an essential contribution to the total action even in the infrared region.Comment: 3 pages, 3 figures, 1 table, uses espcrc2.sty; Lattice2003(topology

Boiling heat transfer enhancement by nano-particles-assembled bi-porous layers

Nanoparticles-assembled bi-porous structure is newly proposed as boiling heat transfer enhancement technique. In order to assemble nanoparticles onto a heat transfer surface as a thin layer, a boiling adhesion method (BAM) is originally introduced in which, water or water/ethanol solution with mono-dispersed nanoparticles is dropped or sprayed onto a high temperature surface, and then the nanoparticles deposit onto the heat transfer surface during the boiling. In addition to that, it is expected that boiling bubbles can produce micro or milli scale of larger pores at the same time, which enables to fabricate bi-porous structure.
