This paper presents the core of a descriptive theory of indirect speech acts, i.e. utterances in which one speech act form is used to realize another, different, speech act. The proposed characterization of indirect speech acts is based on principles of goal formation, viewed in the context of a general structural model of action. The model of action is used to develop rules that characterize a...

Biological functions of antibiotics are not limited to killing. The most likely function of antibiotics in natural microbial ecosystems is signaling. Does this signaling function of antibiotics also extend to the eukaryotic - in particular mammalian - cells? In this review, the host modulating properties of three classes of antibiotics (macrolides, tetracyclines, and β-lactams) will be briefly ...

Background: Translating a known metabolic network into a dynamic model requires reasonable guesses of all enzyme parameters. In Bayesian parameter estimation, model parameters are described by a posterior probability distribution, which scores the potential parameter sets, showing how well each of them agrees with the data and with the prior assumptions made. Results: We compute posterior distr...

veryfew attempts have been made in the past to develop instruments to measure pragmatic knowledge of second language (l2) learners. the absence of such instruments in the literature of english language teaching (elt) underscores the need for the researchers to develop new tests that are specifically designed to assess this crucial but less explored aspect of language learners’ (lls) knowledge. ...
