Asabasis for a systematic approach to investigating the effects ofwritten corrective feedback, this article presents a typology of the different types available to teachers and researchers. The typology distinguishes two sets of options relating to (1) strategies for providing feedback ( for example, direct, indirect, or metalinguistic feedback) and (2) the students’ response to the feedback ( ...

Abstract. Fire is an important source of ozone (O3) precursors. The formation surface O3 can cause damage to vegetation and reduce stomatal conductance. Such processes feed back inhibit dry deposition indirectly enhance O3. Here, we apply a fully coupled chemistry–vegetation model estimate the indirect contributions global fires through O3–vegetation feedback during 2005–2012. emissions directl...
