During the past decade New Zealand has introduced far-reaching reforms in the structure and operation of government departments and agencies. This model has attracted interest in developing countries because it promises significant gains in operational efficiency. But developing countries, which are dominated by informal markets, are risky candidates for applying the New Zealand model. The auth...

ASHER and ALEX LASCARIDES INDIRECT SPEECH ACTS

In this paper, we address several puzzles concerning speech acts, particularly indirect speech acts. We show how a formal semantic theory of discourse interpretation can be used to define speech acts and to avoid murky issues concerning the metaphysics of action. We provide a formally precise definition of indirect speech acts, including the subclass of so-called conventionalized indirect speec...

Model-Theoretic Characterization of Asher and Vieu's Ontology of Mereotopology

We characterize the models of Asher and Vieu’s first-order mereotopology RT0 in terms of mathematical structures with well-defined properties: topological spaces, lattices, and graphs. We give a full representation theorem for the models of the subtheory RT− (RT0 without existential axioms) as p-ortholattices (pseudocomplemented, orthocomplemented). We further prove that the finite models of RT...
