AIHA Hosts Bayesian Decision Analysis TeleWeb

The American Industrial Hygiene Association will host "Introduction to Bayesian-Based Decision Making," an introductory TeleWeb Virtual Seminar, on April 17, 2008, from 2–4:30 p.m. ET. Featured speakers include Paul Hewett, Ph.D., CIH, and J. Barry Graffeo, CIH.

Hewett is the founder and president of Exposure Assessment Solutions Inc. and worked for 25 years as an industrial hygienist for NIOSH's Division of Respirable Disease Studies specializing in the measurement of pneumoconiosis-producing dusts. He is also the author of numerous articles and chapters on exposure assessment and statistics for industrial hygienists, as well as having served as a past chair of the AIHA Exposure Assessment Strategies Committee.

Graffeo is the corporate industrial hygienist at Eli Lilly and Company, and consults with research and manufacturing sites around the world to implement comprehensive exposure assessment programs. He has more than 16 years experience in bulk chemical, biochemical, and pharmaceutical manufacturing, as well as research and development activities. Graffeo has taught numerous exposure assessment courses and coordinated symposiums on the subject and is a past chair of the AIHA Exposure Assessment Strategies Committee.

The first presentation will be an overview of the theory behind Bayesian Decision Analysis, assumptions and limitations, a comparison to standard statistical analysis, as well as an overview of how Bayesian methods permit the explicit use of professional judgment in the calculations.

The second presentation is an introduction to IHDataAnalyst-LiteEdition, which covers an overview of a freeware program for performing standard statistical analyses, plus Bayesian Decision Analysis of occupational exposure data.

The third presentation will address integrating Bayesian-based decision making into the AIHA Exposure Assessment Model, which is based on determining whether the exposure profile falls within one of five exposure ranges.

To register for the seminar, call toll free at (800) 651-7916 or register online at www.aiha.org/Content/CE/DL/TelewebBaysian.htm.
