We generalize stochastic Kripke models and Markov transition systems to stochastic right coalgebras. These are coalgebras for a functor with as an endofunctor on the category of analytic spaces, and is the subprobability functor. The modal operators are generalized through predicate liftings which are set-valued natural transformations involving the functor. Two states are equivalent iff they cannot be separated by a formula. This equivalence relation is used to construct a cospan for logical equivalent coalgebras under a separation condition for the (...) set of predicate liftings. Consequently, behavioral and logical equivalence are really the same. From the cospan we construct a span. The central argument is a selection argument giving us the dynamics of a mediating coalgebra from the domains of the cospan. This construction is used to establish that behavioral equivalent coalgebras are bisimilar, yielding the equivalence of all three characterizations of a coalgebra’s behavior as in the case of Kripke models or Markov transition systems.

This article examines the discursive uses of frequent response initiators by Republican and Democratic presidential candidates in the genre of televised US primary debates. Ten full transcripts of debates held between February and April 2016 are investigated from the perspectives of political discourse studies and conversation analysis. It is shown that the response initiators well, first of all, look, you know and let me speech act verb fulfill specific discursive functions in competitive media discourse. On the textual level, candidates exert (...) power and control by negotiating turn-taking processes and managing the information flow. On the interactional level, competitors use response initiators to frame themselves as likable and competent personas, to establish common ground with voters and to enhance negative perceptions of opponents. Conclusively, in the multilogue of election debates, response initiators significantly contribute to the construction of individual preferability. (shrink)

A close reading of a chapter of Gellius’ Noctes Atticae on the quantity of prefixes reveals that the two prose quotations from the elder Cato, which seem to be inappropriate in a discussion that otherwise consists of nothing but poetic examples, are in fact not at all out of place, since Cato himself offered poetic material in these quotations. Through this, two fragments of Old Latin poetry can be recovered. The first, the ending of a hexameter, is probably taken from (...) a satiric context. The content of the second fragment, an iambic octonarius, may indicate occasional poetry. (shrink)
