RATIONALE, AIMS AND OBJECTIVES We examined the effect of two interventions on both the reliability and validity of regulatory judgments: adjusting the regulatory instrument and attending a consensus meeting. METHOD We adjusted the regulatory instrument. With a randomized controlled trial (RCT) we examined the effect of the adjustments we made to the instrument. In the consensus meeting inspec...

A new improved model is introduced for the performance of inspectors of user requirements documents. The model, which is based on a linearity assumption employs only two non-dimensional metrics in the [0;1] interval. They characterise the error detection ability of the inspectors and their domain knowledge level. It is our experience that one learns to reason with these two metrics. The applica...

The character of cracks is an important parameter in manufacturing of test pieces for UT qualification. In these studies we (Trueflaw and Fortum Nuclear Services) have manufactured 22 cracks by different production methods. Opening of cracks have been manipulated for different values. Sizing of the true dimensions of cracks has been made by destructive tests. These values are the basis for the ...

Introduction An early textbook in hydrology (Mead 1919) contains a remarkable chapter on ground water as well as two chapters on geology. The author, Daniel W. Mead, a professor of hydraulic and sanitary engineering at the University of Wisconsin (now the University of WisconsinMadison), based the text on lecture notes (published earlier, Mead [1904]) for his course in general hydrology. In fac...

This paper introduces the PlaceMemo prototype, a system developed to support road inspectors in their daily work. The concept is based on an ethnographic study conducted at the Swedish National Road Administration-Production during 2000. PlaceMemo supports the articulation work, allowing road inspectors to save, and share, interpretations of objects in their geographically widespread working ar...

A cognitive work analysis of quality inspection in the optical industry has been carried out in order to devise a training programme. The task concerned the inspection of high quality human eyeglass lenses. We conducted an experimental investigation of defect detection and acceptability decision-making tasks in 18 experts and novice inspectors. Detection and decision-making were investigated to...
