We present high‐resolution spectra (1.0 km s−1 FWHM) of the circumstellar Ca K line towards β Pictoris obtained on 1997 June 19 and 20. On the former date a strong absorption component was found at a heliocentric velocity of vhelio = +8 km s−1, that is blueshifted by 14 km s−1 with respect to the main, ‘stable’, circumstellar component at vhelio = +22 km s−1. To our knowledge, this is the first detection of a blueshifted Ca ii component with a strength comparable to the more frequently observed redshifted events. On the following night a blueshifted component was still present, but its strength had decreased significantly; in addition, a strong redshifted component had appeared at vhelio = +54 km s−1 which was absent on the previous night. The implications of these observations for the evaporating ‘comet’ model of spectral variations in the β Pictoris disc are discussed.
Over a period of three years (2006-2008) students entering [university] were asked to complete the Student Leadership Practices Inventory (S-LPI), and 2,855 initial responses were received. Responding students were asked to complete the S-LPI again at the end of their first and third years of study. No significant differences were found in student use of the leadership practices based on age, geographic origin, or whether the student lived on or off campus during his or her first year. Significant differences were found based on students' gender and program of study. Implications for leadership development programming are considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
