The Present Perfect in Non-Native Englishes: A Corpus-Based Study of Variation /by Julia Davydova. The present work is the result of a two-year project (from 2007 till 2009) earned out at the collaborative research centre (SFB 538) on multilinguahsm and at the University of Hamburg. First and foremost, I would like to thank Prof. Peter Siemund, my Doktorvater, for giving me a chance to embark upon a journey that has taken me as far as Bnansk (Russia) and New Delhi (India); for providing input to my work in the form of discussions; for challenging and nurturing and, more importantly, for giving me enough time and space for my ideas to grow. Funding by the Deutsche Forschungsgememschaft is gratefully acknowledged.
