This study uses both risk-risk and risk-dollar approaches to assess intangible health losses associated with multiple sclerosis (MS). Using an estimation approach that adjusts for potential perceptional biases that may effect the expressed risk tradeoffs, we estimated parameters of the utility function of persons with and without MS as well as the degree of subjects" overestimation of the proba...

Endpoint admission control solutions, based on probing a transmission path, have been proposed to meet quality requirements of audio–visual applications with little support from routers. In this paper we present a mathematical analysis of a probe–based admission control solution, where flows are accepted or rejected based on the packet–loss statistics in the probe stream. The analysis relates s...

In many risk management situations, instead of the exact probability values, specialists use a granule to which this probability belongs. Specifically, they use five granules, corresponding to thresholds 10%, 40%, 60%, and 90%. In this paper, we provide an explanation for such non-uniform granulation. 1 Formulation of the Problem In risk management, it is often important to group probabilities ...

We study the recovery results of lp-constrained compressive sensing (CS) with p ≥ 1 via robust width property and determine conditions on the number of measurements for standard Gaussian matrices under which the property holds with high probability. Our paper extends the existing results in Cahill and Mixon (2014) from l2-constrained CS to lp-constrained case with p ≥ 1 and complements the reco...

The Internet uses a window-based congestion control mechanism in TCP (Transmission Control Protocol). In the literature, there have been a great number of analytical studies on TCP. Most of those studies have focused on the statistical behavior of TCP by assuming a constant packet loss probability in the network. However, the packet loss probability, in reality, changes according to packet tran...

This article presents the results of a survey designed to test, with economically sophisticated participants, Ellsberg’s ambiguity aversion hypothesis, and Smithson’s conflict aversion hypothesis. Based on an original sample of 78 professional actuaries (all members of the French Institute of Actuaries), this article provides empirical evidence that ambiguity (i.e. uncertainty about the probabi...

Finite queues with overflow are most natural in communications (in both circuit and packet switch networks). For such queues, there is no simple analytic expression for the loss probability. It is shown however that the principle of call packing leads to • an upper bound (for the loss probability) • an analytic error bound for its accuracy and • a quite reasonable approximation (superior to Erl...

INTRODUCTION Unmedicated Parkinson's disease patients tend to be risk-averse while dopaminergic treatment causes a tendency to take risks. While dopamine agonists may result in clinically apparent impulse control disorders, treatment with levodopa also causes shift in behaviour associated with an enhanced response to rewards. Two important determinants in decision-making are how subjects percei...
