conclusion investigative assessment of breast us by residents is inadvisable. we recommend continued professional resident training to improve the degree of agreement and performance. results for the faculty members, fair-to-good agreement was obtained in all descriptors and final assessment, while for residents, poor-to-moderate agreement was obtained. the areas under the roc curves were 0.78 ...

Although the effects of negative stereotypes and observer pressure on athletic performance have been well researched, the effects of positive stereotypes on performance, particularly in the presence of observers, is not known. In the current study, White males watched a video either depicting Whites basketball players as the best free throwers in the NBA (positive stereotype), Black basketball ...

results the interobserver agreement for sonographic descriptors changed between fair and substantial. the highest agreement was detected for mass orientation (κ=0.66). the lowest agreement was found in the margin (κ=0.33). the interobserver agreement for bi-rads final category was found as fair (κ=0.35). the intraobserver agreement for sonographic descriptors changed between substantial and alm...

Recent developments in optimal observer design for dynamic positioning have led to application of contraction analysis. In this paper a theoretical method for nonlinear optimal observer design and a suboptimal observer using a state-dependent Riccati equation approach are presented. The observer will be compared to an existing observer and its properties and performance is discussed. Early obse...

This paper deals with the design of an H∞-observer to estimate the state variables of the vertical car dynamics to be used for suspension control applications. The proposed methodology allows to cope with both the disturbance decoupling problem (for the road profile effects) and the implementation issue (through observer pole placement). The considered model is a 7 DOF full-car vertical model s...

For the past 10 years, research on the effects of observer presence on test performance has expanded in the neuropsychological literature. Previous studies have shown that the presence of a third party observer is associated with poorer performance on tests of effort, attention, concentration, learning, and memory. The present study was designed to investigate whether performance on tests of ex...
