A PEM is an objective measurement device showing a high correlation between information from the operator's log data, particularly with regard to the exposure index
of the PEM limited to mobile communication.
One possible explanation for this pattern of results is that the neighborhood poverty exposure index
failed to capture other important aspects of spatial disadvantage that may contribute to poor birth outcomes among island-born Puerto Rican women.
Among the results of our study was the fact that the average sun exposure index
of the population studied was 19.6; because the index ranged from 0 to 38, this figure would seem to indicate that the members of the study population experienced an average level of sun exposure.
This exposure index
was not a perfect measure of wave energy because factors such as depth, slope, offshore reefs, wave refraction, and wind direction were not taken into account.
The personal exposure index
is also called the air quality index in the inhaled air.
The measured concentration of isocyanate aerosols during the application of the polyurethane lacquer is low (exposure index
is less than 0.1 on the person that shifts the chairs).
The other seven items were coded 1 for "never," 2 for "hardly ever," 3 for "sometimes," and 4 for "regularly." Cronbach's coefficient alpha for the eight-item News Media Exposure Index
Panel B presents analogous results using the poverty exposure index
to measure social access with quite similar results.
If the same analysis is done omitting districts in which Smart Choices was not taught at all, the overall exposure index
is still significantly higher in the live workshop districts.
All five workers who were tested had urine mercury levels exceeding the American Conference of Governmental Industrial Hygienists (ACGIH) biologic exposure index
of 20.0 [micro]g/g creatinine, and two had tremor on physical exam.
The team used mean daily temperature as the exposure index
, with data back to 1985 in some locations.
We modeled health parameters with the HASI exposure index
to confirm the results derived from the single-pollutant models.
