The exercise of pre-identifying parks using geocoded satellite/administrative data prior to observers entering the field facilitated the on-site evaluation process.
Inter-observer variability was not measured, but limited by training of observers prior to the start of the observations.
This was also found by Miller et al (2000) who showed that prion infection in deer increased the rate of predation of deer by mountain lions (Puma concolor) nearly fourfold, even if few of the deer killed were recorded as "noticeably ill" by field observers prior to their deaths [31].
Few of the deer killed by mountain lions were recorded as noticeably ill by field observers prior to their deaths, suggesting that relatively subtle changes in behavior or condition may have been sufficient cues to draw a predator's attention to infected individuals or increase their vulnerability to attack.
Prior to presentation, observers were notified whether the target stimuli would be visual or auditory.
No consensus in how to measure was agreed on between the observers prior to the study.
A manual of detailed protocols was developed and used to train and standardise the observers prior to the study, and for reference during the study.
In order to mimic that various interpreters are using the methods during clinical work, and for screening in health programs, no consensus in how to measure the relevant diameters was agreed on between the observers prior to the study.
In this paper, we present data that suggest specific priors in how observers infer 3D structures from 2D cross-sections; these priors influence both the accuracy of observers' inferences and recognition of when accurate inferences are not possible.
Although the observation technique used in this study was standardised and the observers trained prior to commencement, observation has the potential to influence the activity of the staff or patients observed.
