In a world marked by fluctuating borders, diverse identities, and global interconnectedness, the concepts of hospitality and hostility present complex meanings and challenges. This conference invites scholars and researchers to explore the diverse manifestations of hospitality and hostility across linguistics, literature, culture, social sciences, and political discourse. From acts of welcoming to experiences of exclusion, from cultural exchange to conflict, this theme highlights the delicate balance between openness and resistance, friendship and enmity, inclusion and exclusion.
