Complete Monotonicity, Background Risk, and Risk Aversion.

This paper analyzes how the statistical properties of a risk affect the attitutde of individuals towards accepting another independent risk. We conduct the analysis for the class of increasing utility functions having all their derivatives with alternating sign.RISK;DECISION MAKING;UNCERTAINTY

New Measurements of the 81Kr Atmospheric Abundance

We have determined the 81Kr activity to be (0.067 +/- 0.003) decay/min. 1 krypton. Using this activity in conjunction with our new measurement of the 80 KR(n,y)81Kr reaction cross-section of (12 +/- 4)b, we infer that the 81Kr activity is 1.5-2.0 times that which would be calculated calculated using the current cosmic ray flux. This implies that the average cosmic ray intensity in the atmosphere during the 81Kr life-time was greater than the current intensity, a fact that has implications for the 14C time scale.This material was digitized as part of a cooperative project between Radiocarbon and the University of Arizona Libraries.The Radiocarbon archives are made available by Radiocarbon and the University of Arizona Libraries.

The first cryogenic dark matter experiment

An experimental search for dark matter particle candidates using cryogenic detectors requires a low radioactive background environment. We discuss the status of a cryogenic dark matter experiment to be performed in the Stanford Underground Facility. The detectors will be cooled in a specially designed cryostat connected to a modified side access Oxford 400 dilution refrigerator. Details of the cryostat design and its operating performance are presented. The effectiveness of the multi-level shield surrounding the cryostat, as well as the background levels we expect to achieve in the pilot experiment are discussed. Finally, we examine the limits which can be set on dark matter candidates with such an experiment
