The Accession of Finland and Sweden to NATO: Geopolitical implications for Russia’s position in the Baltic Sea region
... particular, Frederik Mertens, an analyst at the Hague Centre for Strategic Studies, argues that NATO in the Baltic already has an overwhelming advantage over Russia not only in the sea but also in air potential, and with Sweden joining NATO, Russian surface ships can only rely on ground-based air defence. There hardly is a spot of the Baltic left, Mertens argues, where a Russian surface ship cannot expect the imminent attack of an advanced sea-skimming missile. Besides, Sweden will be much more integrated ...

The author shows how, in the early seventies, both cultural anthropology and TS saw a change in paradigm that brought the two disciplines closer at the surface level (as the metaphor of culture as a text gained grounds), but that draw them very much apart from an epistemological viewpoint. Indeed, while ethnography was undertaking an interpretive turn, TS chose to define itself as an empirical discipline ...
