Successfully promoting engagement within learning environments is a subject of increasing attention within the AI in Education community. Evidence is mounting that game-based learning environments hold great potential to engage students, but disengaged behavior is still observed. Devising adaptive strategies to re-engage students in the learning task is a key open research question. Toward that...

This article explores ways to promote symmetrical dialogue among knowledge-practices of artisanal fishing communities, primary education teachers, and academic researchers in the state Bahia, Brazil. We describe multiple engagements an inter- transdisciplinary project that integrates research, educational, conservation activities two communities living estuarine ecosystem. Most community member...

Aiming at robust spoken dialogue interaction in motorcycle environment, we investigate various configurations for a speech front-end, which consists of speech pre-processing, speech enhancement and speech recognition components. These components are implemented as agents in the Olympus/RavenClaw framework, which is the core of a multimodal dialogue interaction interface of a wearable solution f...

In this article, VET-related collaborative research is discussed as a potential transformative experience for workers/work collectives/work organizations. Three main ideas in the creation of dialogical frameworks for collaborative research are presented: (a) Vygotsky’s research focus on provoking development in order to study it (Vygotsky, 1934/1986); (b) Oddone’s ideas on close collaboration w...

This paper describes our motivation for and approach to the design and implementation of mixed-initiative dialogue systems for collaborative problem solving. Our model allows true mixed-initiative dialogue, where goals (and other joint commitments) can come from either the user or the system. The system’s behavior with respect to its commitments is driven by a formal model of collaboration base...

The status and the treatment of detainees in the ‘war on terror’ is one of the major contentious topics in current transatlantic relations. This article aims to explain the reasons for transatlantic disunity on this issue as well as to assess its impact on the stability and the persistence of the transatlantic security community. I argue that divergent strategic cultures are the main source of ...

We describe a model for task-driven, naturallanguage-based human-robot interaction where the roles of the two participants are fully interchangeable, both at the conversational level and at the task level. This model provides a general treatment of joint-action dialogue, and also allows models based on the analysis of human-human joint-action dialogues easily to be implemented and evaluated. I....
