This paper summarizes two companion studies that were designed to investigate the impacts of an inquiry teaching method on Earth science students’ achievement and attitudes toward Earth science in secondary schools. Subjects were 557 Earth science students (9th grade) enrolled in 14 Earth science classes. Two Earth science units including topics of astronomy and meteorology were developed and t...

BACKGROUND Differences in the cortisol response have been reported between children exhibiting the inattentive and hyperactive/impulsive subtypes of attention deficit hyperactivity disorder. However, there is no such information about adults. The aim of the present study was to determine the possible differences between the combined and inattentive subtypes in the cortisol response to stress. ...

The imminent availability of large arrays of large light collectors deployed to exploit atmospheric Cherenkov radiation for gamma-ray astronomy at more than 100 GeV, motivates the growing interest in application of intensity interferometry in astronomy. Indeed, planned arrays numbering up to one hundred telescopes will offer close to 5,000 baselines, ranging from less than 50 m to more than 100...

The high-latitude Galactic H I cloud toward the extragalactic radio source 3C 225 is characterized by very narrow 21 cm emission and absorption indicative of a very low H I spin temperature of about 20 K. Through high-resolution optical spectroscopy, we report the detection of strong, very narrow Na I absorption corresponding to this cloud toward a number of nearby stars. Assuming that the turb...

Abstract The crosswise model is an increasingly popular survey technique to elicit candid answers from respondents on sensitive questions. Recent studies, however, point out that in the presence of inattentive respondents, conventional estimator prevalence a attribute biased toward 0.5. To remedy this problem, we propose simple design-based bias correction using anchor question has item with kn...
