As Director of the Office of Scientific Research and Development, Dr. Vannevar Bush has coordinated the activities of some six thousand leading American scientists in the application of science to warfare. In this significant article he holds up an incentive for scientists when the fighting has ceased. He urges that men of science should then turn to the massive task of making more accessible o...

How do experienced users extract information from a complex visualization? We examine this question by presenting experienced weather forecasters with visualizations that did not show the needed information explicitly and examining their eye movements. We replicated Carpenter & Shah (1998) when the information was explicitly available on the visualization. However, when the information was not ...

The importance of socioeconomic position, measured at multiple levels (e.g., individual, household, area) and across the life course, for studying health disparities is now well recognized (1–7). Our multilevel study (8) reported that individual-based socioeconomic measures (IBSMs) and area-based socioeconomic measures (ABSMs) together capture birth weight inequalities that otherwise would have...

Background: Many studies have shown that contaminated medical equipments act like a vector for crossinfection. Infection control programmes are effective in decreasing hospital-acquired infection rate, however, the implementation of such programmes is hindered by poor compliance of health care workers. Methods: Random selection of health care workers, at our institution, was given questionnaire...

OBJECTIVE In this study, we investigated the accuracy of measuring walking steps with commercially available pedometers and an accelerometer-based step-counter in normal and overweight children. Our primary hypothesis was that commercially available pedometers are not an accurate measure of walking steps in normal and overweight children while walking. Our secondary hypothesis was that the acce...
