to strictly alternating onsets (symbolised by "C") and nuclei ("V") - all surface clusters sandwich empty categories, which conform to the ECP (see above). This version of GP has become known as Strict CV Phonology or CVCV Phonology, and is currently the most widely accepted model of prosodic structure within GP circles. (See Tobias Scheer's and Péter Szigetvári's work.) The other major current trend in GP is represented by Pöchtrager and his colleagues, who propose GP 2.0, another version of GP that strives to further reduce the number of elements by capturing manner of articulation (old (ʔ) and (h)/(H)) as well as element (A) with structure. Unlike CVCV Phonology's flat prosodic structure, configurations within GP 2.0 remain hierarchical and involve multiple layers, with the nodes entering into governing and m-commanding relations, very much as in X-bar theory syntax. Further work in GP and GP-friendly frameworks includes ET-based research in laryngeal phonology, as well as analyses in Loose CV Phonology and Precedence-Free Phonology. GP-ists and related researchers regularly meet at the Government Phonology Round Table (GPRT), a semi-informal meeting originally (starting in 1997) organised by teams of scholars at universities in Budapest, Hungary and Vienna, Austria. Later, a few events were organised in Slovenia. Recently, Budapest and Vienna have taken turns again as venues. Further reading Cyran, Eugeniusz (2003) Complexity Scales and Licensing in Phonology.
