Reducing the Risk of Human ExtinctionRisk Analysis - Tập 27 Số 5 - Trang 1335-1344 - 2007
Jason Matheny
In this century a number of events could extinguish humanity. The probability of these events may be very low, but the expected value of preventing them could be high, as it represents the value of all future human lives. We review the challenges to studying human extinction risks and, by way of example, estimate the cost effectiveness of preventing extinction‐level asteroid impacts.
Resource Distribution in Multiple Attacks with Imperfect Detection of the Attack OutcomeRisk Analysis - Tập 32 Số 2 - Trang 304-318 - 2012
Gregory Levitin, Kjell Hausken
This article extends the previous research of consecutive attacks strategy by assuming that an attacker observes the outcome of each attack imperfectly. With given probabilities it may wrongly identify a destroyed target as undestroyed, and wrongly identify an undestroyed target as destroyed. The outcome of each attack is determined by a contest success function that depends on the amount ...... hiện toàn bộ
The Aggregation of Expert Judgment: Do Good Things Come to Those Who Weight?Risk Analysis - Tập 35 Số 1 - Trang 12-15 - 2015
Roger Cooke
This responds to an “evaluation” of the classical model for structured expert judgment by Bolger and Rowe in this issue. This response references extensive expert judgment performance data in the public domain which played no role in their evaluation.
A Probabilistic Model for the Failure Frequency of Underground Gas PipelinesRisk Analysis - Tập 18 Số 4 - Trang 511-527 - 1998
Roger Cooke, Eric Jager
A model is constructed for the failure frequency of underground pipelines per kilometer year, as a function of pipe and environmental characteristics. The parameters in the model were quantified, with uncertainty, using historical data and structured expert judgment. Fifteen experts from institutes in The Netherlands, the United Kingdom, Italy, France, Germany, Belgium, Denmark, and Canada...... hiện toàn bộ
Quantitative Risk Estimation for a Legionella pneumophila Infection Due to Whirlpool UseRisk Analysis - Tập 33 Số 7 - Trang 1228-1236 - 2013
Martijn Bouwknegt, Jack Schijven, J.A.C. Schalk, Ana Maria de Roda Husman
Quantitative microbiological risk assessment was used to quantify the risk associated with the exposure to Legionella pneumophila in a whirlpool. Conceptually, air bubbles ascend to the surface, intercepting Legionella from the traversed water. At the surface the bubble bursts into dominantly noninhalable jet drops and inhalable film dr...... hiện toàn bộ
Socioeconomic Vulnerability and Adaptation to Environmental Risk: A Case Study of Climate Change and Flooding in BangladeshRisk Analysis - Tập 27 Số 2 - Trang 313-326 - 2007
Roy Brouwer, Sonia Akter, Luke Brander, Enamul Haque
In this article we investigate the complex relationship between environmental risk, poverty, and vulnerability in a case study carried out in one of the poorest and most flood‐prone countries in the world, focusing on household and community vulnerability and adaptive coping mechanisms. Based upon the steadily growing amount of literature in this field we develop and test our own analytica...... hiện toàn bộ
