Three training conditions were compared in a task of learning locations of cities on a map: one in which participants could avoid errors by searching for the name of the correct city, and two others in which either immediate feedback after each response or delayed feedback after all responses had been …

This letter to the editor argues that the assumption of a single value for the acetate recovery factor in carbon-13 stable isotope research for different individuals, can lead to significant errors in the outcomes of substrate utilization measurements.

OBJECTIVES: To evaluate the results of an ergonomic-educational course for nurses we assessed the number and percentage of harmful postures and of ergonomic and biomechanical errors made before and after the course. We also studied the perceived physical exertion. MEANS AND METHODS: In all, 12 nurses …

OBJECTIVES: The objectives of this study were (i) To establish whether it is possible to assess by means of a check-list in a reliable way errors which violated biomechanical and ergonomical principles during nursing tasks, and (ii) to study the effectiveness of an ergonomic-educational course by using …

Estimation of the factor model by unweighted least squares (ULS) is distribution free, yields consistent estimates, and is computationally fast if the Minimum Residuals (MinRes) algorithm is employed. MinRes algorithms produce a converging sequence of monotonically decreasing ULS function values. Various …
