Perceptual disturbances and motion sickness are often attributed to sensory conflict. We investigated several conditions: head movements in microgravity, periodic motions in 1-g, and locomotion with vestibular disorders. In every case, linear vectors such as linear and gravitational acceleration are crucial factors, as previously found for head movements in artificial gravity, and thus the impo...

Purpose: To compare the usage of ‘provocative’ terms in two patient education booklets for lumbar surgery. Background: The recently completed FASTER trial failed to support the use of an evidence-based educational booklet to significantly improve postsurgical outcomes over rehabilitation and usual care. The use of a different booklet in another recently completed trial resulted in a significant...

Coronary artery spasm (CAS), an intense vasoconstriction of coronary arteries that causes total or subtotal vessel occlusion, plays an important role in myocardial ischemic syndromes including stable and unstable angina, acute myocardial infarction, and sudden cardiac death. Coronary angiography and provocative testing usually is required to establish a definitive diagnosis. While the mechanism...

This study analyses school mathematics teachers’ attitudes towards using provocative questions in teaching and assessment as a potential pedagogic innovation. By question, we mean here question designed to deliberately mislead the solver. It normally calls for an impossible task. For example, might ask proof of something that is not provable or show existence solution equation does have solutio...
