The information conveyed by any utterance is a motley ensemble. Utterances carry content about the world as it is according to the speaker, but also about speakers’ attitudes, the way they speak, what has been said before, and so on. There are many kinds of information that are conveyed by way of language, and differences in kind correlate with differences in status. Presupposed information exh...

This paper presents a pragmatic approach to Discourse Representation Theory (DRT) in an attempt to address the pragmatic limitations of DRT (Werth 1999; Simons 2003). To achieve a more pragmatic DRT model, this paper extends standard DRT framework to incorporate more pragmatic elements such as representing agents’ cognitive states and the complex process through which agents recognize utterance...

This paper discusses some issues in various approaches to Discourse Representation Theory. This is not intended to be detailed descriptions of various systems but general comparisons between both implementations of DRT and descriptions of DRT in some other context (e.g. a situation theoretic framework). The intention is to show how close (or how diierent) these approaches are and which aspects ...

This paper shows an extended Discourse Representation Theory (DRT) model which represents clarification dialogue and clarification dialogue acts and relates them to agents’ intentions. Agents’ intentions are linked to the dialogue acts associated with their utterances. The effect dialogue acts have on the speaker and the hearer is translated into an extended computational DRT model and linked t...

Directed-ratchet transport (DRT) in a one-dimensional lattice of spherical beads, which serves as a prototype for granular chains, is investigated. We consider a system where the trajectory of the central bead is prescribed by a biharmonic forcing function with broken time-reversal symmetry. By comparing the mean integrated force of beads equidistant from the forcing bead, two distinct types of...

In developed countries, Demand Responsive Transport (DRT) (loosely termed ‘paratransit’ in US parlance) emerged in the 1970s to serve the specialist niche market of people with mobility difficulties. DRT systems are starting become a mainstream public transport mode and this paper examines mainstream public transport DRT schemes from around the world that have failed, in order to identify the r...

IN BRIEF This article describes a study to gain insight into the utility and perceived feasibility of the American Diabetes Association's Diabetes Risk Test (DRT) implemented by nurse practitioners (NPs) in the retail clinic setting. The DRT is intended for those without a known risk for diabetes. Researchers invited 1,097 NPs working in the retail clinics of a nationwide company to participate...

We discuss some consequence relations in DRT useful to discourse semantics. We incorporate some consequence relations into DRT using se-quent calculi. We also show some connections of these consequence relations and existing partial logics. Our attempt enables us to display several versions of DRT by employing different consequence relations.

BACKGROUND In the last 10 years, dopamine replacement therapy (DRT) has become a well-known risk factor for developing an impulse control disorder, such as gambling disorder (GD). Another medication, aripiprazole (ARI), has been more recently identified as another risk factor. Dopamine replacement therapy and ARI share a dopamine agonist action. Our work aimed at comparing patients with PG acco...
