Descriptions of different languages help us understand what speakers of different languages share worldwide. At the same time, having descriptions of languages available can also change local education and open our eyes to cultural and linguistic diversity. But what if a language has not yet been (fully)…

When alumnus Jonathan Katzman started his master's programme in Russian and Eurasian Studies, he didn't foresee how useful those skills would be in the near future. Now, he manages a refugee centre for Ukrainians who have fled their war-torn country.

This research cluster aims to analyse and interpret the formation and transmission of Graeco-Roman culture by exploring the relationships between cultural products (texts, objects, practices) and their societal and historical contexts.

Computational thinking, programming, and algorithms form the basic of many of the things that are shaping our world, the way we work, interact, organize ourselves, and even spend our free time with social networks, streaming media, and games. And this transformation is far from being complete, it is…

Like any language, the natural sign languages (henceforth: SLs) of deaf communities differ from each other in their grammars and lexicons. A growing number of studies indicates that SLs make use of the gestures of hearing speakers to build linguistic structure. This implies that variation and similarities…

Morality, mathematics, geometry, geography, music, navigation, and language are traditionally viewed as uniquely human cultural achievements and abilities. The study of their development and variation is classified as part of the humanities and social sciences. These fields have been mainly studied…
