We also accounted for the clustering of children by mothers and included fixed effects of survey years in the model, specifying the exposure time for each child within each age band as defined above.
However, until interrater reliability is specified, the exposure measures cannot be assumed to be consistent across locations.
The consent form did not specify the exposure biomarkers to be analyzed, include specific language about reporting these results to the study families, or include the option to decline receipt of test results.
In addition, the questionnaire did not include details on frequency of use, chemicals used, or conditions of use, which might have specified the exposure but might also have been more difficult to recall.
The response variability changes with the experimental setup, which is specified by the exposure condition as well as the data source factors.
A digital camera could easily store a table that specifies the ideal number of exposures for any set of circumstances, Hasinoff says, and the camera could have a distinct operational setting that invokes the table.
It remains possible that the lead exposure during adulthood that we measured directly via tibia lead is a proxy for lead exposures and its consequences endured during childhood and, therefore, that the association between tibia lead and cognition mis specifies the importance of adult exposures.
For many observations, it is only necessary to specify the instrument, the exposure time, and the target coordinates.
In this study, the indigenous leaders of the seven communities requested the study and set the research question; they specified the cultural exposures of interest; they participated in the design and testing of instruments; they led interpretation of results; and they are the primary research users, sharing the results with their communities in support of traditional health practices.
Wood composites have shown very good performance, and substantial service lives when correctly specified for the exposure risks present.
