We calculate the line shape and linewidths for electromagnetically induced transparency EIT in optically thick, Doppler broadened media buffer gasses are also considered . In generalizing the definition of the EIT linewidth to optically thick media, we find two different linewidth definitions apply depending on whether the experiment is pulsed or continuous wave cw . Using the cw definition for...

We investigated whether students liked and learned more from PowerPoint presentations than from overhead transparencies. Students were exposed to lectures supported by transparencies and two different types of PowerPoint presentations. At the end of the semester, students preferred PowerPoint presentations but this preference was not found on ratings taken immediately after the lectures. Studen...

Existing measures of aid transparency overwhelmingly focus on how much information donor agencies are willing to share with the international community, overlooking that is about increasing citizens' access in order improve government accountability. In this article, we present Citizen Aid Transparency Dataset (CATD). Using factor and correlation analysis, show CATD captures a different dimensi...
