Technology Design As Educational Research: Interweaving Imagination, Inquiry & Impact
New models of the research projects that include technology design are needed that draw upon the idealistic potential of technology, but engage with the practical problems of educational reform in a rapidly changing society.

Costs Of ICT Use In Higher Education
This article focuses on the costs of use of Information and Communication Technologies (ICT) for teaching and learning in higher education, bearing in mind that these technologies also support a wide range of other core activities in higher education institutions.

Prosody-Based Automatic Segmentation of Speech into Sentences and Topics
Using decision tree and hidden Markov modeling techniques, we combine prosodic cues with word-based approaches, and evaluate performance on two speech corpora, Broadcast News and Switchboard. Results show that the prosodic model alone performs on par with, or better than, word-based statistical language models–for both true and automatically recognized words in news speech.

A Survey of Research in Distributed, Continual Planning
In this article, we describe a new paradigm for planning in complex, dynamic environments, which we term distributed, continual planning (DCP). We argue that developing DCP systems will be necessary in order for planning applications to be successful in these environments.

Coordinating Planning Activity and Information Flow in a Distributed Planning System
Distributed SIPE (DSIPE) is a distributed planning system that provides decision support to human planners in a collaborative planning environment.

Data-Driven Subclassification of Disfluent Repetitions Based on Prosodic Features
This study delves into the acoustic and prosodic information of repetitions, one of the most common disfluencies. A hierarchical clustering of prosodic features reveals three subsets of repetitions, each reflecting different problems in planning.

Phonetic Consequences of Speech Disfluency
Analyses of American English show that disfluency affects a variety of phonetic aspects of speech, including segment durations, intonation, voice quality, vowel quality, and coarticulation patterns. These effects provide clues about production processes, and can guide methods for disfluency processing in speech recognition applications.

Modeling the Prosody of Hidden Events for Improved Word Recognition
We investigate a new approach for using speech prosody as a knowledge source for speech recognition. The idea is to penalize word hypotheses that are inconsistent with prosodic features such as duration and pitch.
