National Early Intervention Longitudinal Study (NEILS): Service Record A
For the study, every six months an early intervention professional completed a questionnaire on received services, including information regarding the transition out of early intervention.

National Early Intervention Longitudinal Study (NEILS): Service Record B
An early intervention professional completed a questionnaire on the services provided to each NEILS family, including information regarding the transition out of early intervention. Version A of the service record was used for each six-month period the child was in early intervention until version B of the service record was used.

A Prosody-based Approach to End-of-Utterance Detection That Does Not Require Speech Recognition
In this paper we demonstrate that the improvements due to the prosodic knowledge can be realized largely without alignment information, i.e., without requiring a speech recognizer. A prosodic end-of-utterance detector using only speech/nonspeech detection output is still considerably more accurate and has lower latency than a baseline system based on pause-length thresholding.

Fast Symbolic Evaluation of C/C++ Preprocessing Using Conditional Values
We present a new approach for symbolic evaluation that can efficiently compute these conditions by binding variables to conditional values and avoiding the path feasibility analysis of traditional symbolic evaluation.

Interactive Execution Monitoring of Agent Teams
We describe a monitoring framework for integrating many domain-specific and task-specific monitoring techniques and then using the concept of value of an alert to avoid operator overload.

Design Patterns For Assessing Science Inquiry (Padi Technical Report 1)
This paper reports progress on one facet of PADI: design patterns for assessing science inquiry. Design patterns bridge knowledge about aspects of science inquiry that one would want to assess and the structures of a coherent assessment argument, in a format that guides task creation and assessment implementation.
