The book presents the results of multi-parameter corpus research on Polish and English scientific discourses in the field of Linguistics. Highlighting the relevance of contextual variables (including time, culture, L1 vs. L2 language) in research framework, the study develops a discourse model of the scientific article, integrating paradigmatic, interpersonal and textual dimensions. The model is applied to investigate distribution patterns of linguistic exponents of claim-making and claim-challenging, i.e. two processes fundamental to scientific argumentation. The results show the changes which English and Polish linguistic discourses underwent between 1980 and 2010, and the extent to which English as lingua franca of modern science affects Polish L1 and English L2 linguistic discourses.

The volume brings together papers emerging from the GlobE conference (University of Warsaw). The authors explore major topics in Discourse Studies, offering insights into the field's theoretical foundations and discussing the results of its empirical applications. The book integrates different lines of research in Discourse Studies as undertaken at academic centres Europe-wide and beyond. In this diversity, the editors identify certain dominant lines of study, including (new) media discourse, political discourse in the age of social/digital media, or professional discourse in globalized workplace contexts. At the same time, the volume shows that Discourse Studies not only investigate emerging language phenomena, but also critically reassess research issues formerly addressed.

The volume takes a close look at discourse perspectives on academic genres. In the context of scientific communication and the evolution of postmodern culture and society, academic genres have undergone various changes. The study shows that cultural heterogeneity of academic genres, styles and discourses now gives way to an increasing hybridization and discusses theoretical aspects of this process. The second part focuses on specific dimensions of hybridization, in particular between global and local academic genres and discourses, and between real and virtual ones.
