Identifying Etiological Agents Causing Diarrhea in Low Income Ecuadorian Communities
Autor: Gabriel Trueba, Martha Eguiguren, Gabriela Vasco, Joseph N. S. Eisenberg, Richard Atherton, Thamara Andrade, Manuel Calvopiña, William Cevallos
Continued success in decreasing diarrheal disease burden requires targeted interventions. To develop such interventions, it is crucial to understand which pathogens cause diarrhea. Using a case-control design we tested stool samples, collected in bot

Annual and Multi-Year Variability in Ozone Expected Exceedances
Autor: Thomas McCurdy, Richard Atherton
Publikováno v: Journal of the Air & Waste Management Association. 41:1189-1194
Ozone data from 184 metropolitan statistical areas (MSAs) for the time period 1979-1989 were analyzed to: (1) put the large number of O3 exceedances observed in 1988 into perspective, and (2) determine if increasing the averaging time used to calcula

Variability of ozone air quality indicators in selected metropolitan statistical areas
Autor: Richard Atherton, Thomas McCurdy
Publikováno v: Journal of the AirWaste Management Association. 40(4)
This article analyzes numerical variability in ozone air quality data to understand how this variability affects the number of violations seen each year in metropolitan statistical areas (MSAs). Three commonly cited violation indices are used: (1) th
