From the Editors


  • Michael Greenberg,

  • Karen Lowrie

The June 2011 issue contained the first part of our risk regulation theme issue. September presents the second segment, beginning with an introductory editorial by Lisa Robinson, followed by four perspectives and three research papers.

This issue also offers four research articles on three themes: air toxins, food contamination, and homeland security. Supported by Argentina's Agency for the Promotion of Science and Technology, Alejandro Acquesta et al. created a simulation process that estimates damage associated with airborne chemical exposures. They tested the model with chlorine in the City of Pilar, which is part of Buenos Aires Province.

Funded by the European Union Integrated Project BIOTRACER, J. H. Smid et al. built a stochastic simulation model to track concentrations of Salmonella in a Dutch pork slaughterhouse, leading to a better understanding of the sources of contamination.

Ralph Keeney and Detlof von Winterfeldt discuss the logic of building a value model that defines objectives and metrics for these objectives, builds a utility function, and finds tradeoffs that can be used to make homeland security investments.

The issue ends with a fascinating effort by Jason Merrick and Gregory Parnell, supported by the U.S. Department of Homeland Security, to build and test PRA and intelligent adversary tools for counterterrorism.

We are pleased to announce the hiring of two editors. Joining our staff as Associate Editor for the Risk Perception and Communication Area is Katherine McComas, who is an Associate Professor of Communication at Cornell University and has served on SRA's Communications Committee since 2008. Sally Kane, an independent consultant and newly elected president of SRA's National Capital Area Chapter, will be our first Book Review Editor. In this new role, Sally will expand our current book review offerings and she welcomes your ideas.
