Fogarty International Scholars in Occupational & Environmental Health (M Keifer, PI; Daniell, co-PI)
The major goal of this project is to provide Occupational & Environmental Medicine research and training opportunities to physicians and scientists in Southeast Asia.
Third International Scientific Conference on Occupational and Environmental Health. (NIOSH; M Keifer, PI; Daniell, co-PI)
This grant supports the third offering of this international conference, scheduled to occur in October 2008 in Hanoi, Vietnam.
Effectiveness training and reinforcement on HPD use among construction workers. (NIOSH; N Seixas, PI; Daniell, investigator)
This study is designed to assess the effectiveness of three interventions on hearing protector use: a standard hearing conservation training session, use of a novel personal noise level indicator, and follow-up reinforcement training.
