How to assess intra- and inter-observer agreement with quantitative PET using variance component analysis:a proposal for standardisation [PDF]

open access: yes, 2016
BACKGROUND: Quantitative measurement procedures need to be accurate and precise to justify their clinical use. Precision reflects deviation of groups of measurement from another, often expressed as proportions of agreement, standard errors of measurement,

Spatial Models to Account for Variation in Observer Effort in Bird Atlases

open access: yes, 2017
To assess the importance of variation in observer effort between and within bird atlas projects and demonstrate the use of relatively simple conditional autoregressive (CAR) models for analyzing grid-based atlas data with varying effort. Pennsylvania and

Longitudinal Intergroup Contact Effects on Prejudice Using Self- and Observer-Reports [PDF]

open access: yes, 2012
Longitudinal effects of intergroup contact on prejudice were investigated in a sample of 65 young adults (Sample 1) and a sample of their close friends (Sample 2, N = 172), adopting a full cross-lagged panel design.

Dynamic urban projection mapping [PDF]

open access: yes, 2017
“Dynamic projection mapping” is a variation of the best-known “projection mapping”. It considers the perceptual analysis of the urban landscape in which the video projection and the observer’s displacement speed are hypothesized.

Observer Variation in Esophageal Pressure Assessment

open access: yesGastroenterology, 1973
Esophageal pressure tracings of 10 normal subjects were used to determine the observer variation in assessing base line pressures and sphincter landmarks. These parameters were identified by two observers on two occasions. Comparison was made between one observer’s two assessments (intraobserver variation), and between the assessments made by the two ...

Observable Variations in Human Sex Ratio at Birth [PDF]

open access: yesPLOS Computational Biology, 2020
AbstractThe human sex ratio at birth (SRB), defined as the ratio between the number of newborn boys to the total number of newborns, is typically slightly greater than 1/2 (more boys than girls) and tends to vary across different geographical regions and time periods. In this large-scale study, we sought to validate previously-reported associations and
