Discourse Studies is a bimonthly peer-reviewed academic journal that covers the field of discourse analysis, especially articles that offer a detailed, systematic and explicit analysis of the structures and strategies of text and talk, their cognitive basis and their social, political and cultural functions. It specifically also publishes studies in conversation analysis. The journal was established in 1999 by Teun A. van Dijk.
The brightness of the Sun varies on all time scales and wavelengths. An EU-funded initiative is gathering scattered observations from over 25 instruments to accurately represent how solar irradiance variability influences Earth's climate.
