Several issues associated with the hazard identification and dose response assessment of trichloroethylene are discussed. These issues include the identification of TCE’s critical effect and overall cancer weight of evidence, the use of the recently harmonized TCE PBPK model for improving extrapolations from experimental animal to humans, an understanding of uncertainty in dose response assessm...

Many aspects of human motor behavior can be understood using optimality principles such as optimal feedback control. However, these proposed optimal control models are risk-neutral; that is, they are indifferent to the variability of the movement cost. Here, we propose the use of a risk-sensitive optimal controller that incorporates movement cost variance either as an added cost (risk-averse co...

We compare capital requirements derived by tail conditional expectation (TCE) with those derived by tail conditional median (TCM) and find that there is no clear-cut relationship between these two measures in empirical data. Our results highlight the relevance of TCM as a robust alternative to TCE, especially for regulatory control.

We present results from laboratory emissions markets designed to investigate the effects of price controls and permit banking on limiting permit price risk. While both instruments reduce between-period price volatility and within-period price dispersion, combining price controls and permit banking yields important benefits. Banking alone produces high permit prices in earlier periods that fall ...

In statistical disclosure control of tabular data, sensitivity rules are commonly used to decide whether a table cell is sensitive and should therefore not be published. The most popular sensitivity rules are the dominance rule, the p%-rule and the pq-rule. The dominance rule has received critiques based on specific numerical examples and is being gradually abandoned by leading statistical agen...

The post earthquake collapse is one of the important causes of the mountain town houses damaged and traffic congestion, it has important significance to carry on the scientific and reasonable assessment to take preventive measures accordingly. Aiming at the complexity of post earthquake collapse formation mechanism and the uncertainty of evaluation index, according to evidence theory and fuzzy ...

We present an approach for evaluating risk using risk–contributing factors. This approach could be applied recursively to a hierarchy of risk–contributing factors. We also use a MANET scenario to demonstrate how the approach may be applied. We believe that the scenario covers some of the most important risk factors regarding access control for information in a MANET. The set of risk factors dis...

The purposes of this paper are two-fold. On the one hand, we shall provide a decision analysis justification for the Value at Risk (VaR) approach based on ex-post, disappointment decision making arguments. We shall show that the VaR approach is justified by a disappointment criterion. In other words, the asymmetric valuation between ex-ante expected returns above an appropriate target return an...

In this paper, we develop a new model to describe a dynamic revenue-sharing problem between an online shopping mall and a store in an E-commerce market. We formulate the revenue-sharing problem as a dynamic principal-agent problem, which is then transformed to a risk-sensitive stochastic optimal control problem where the objective of the risk-averse shopping mall is to find a risk-sensitive rev...
