Direct Modeling of Prosody: An Overview of Applications in Automatic Speech Processing
We describe a direct modeling approach to using prosody in various speech technology tasks. Prosodic features are extracted directly from the speech signal and from the output of an automatic…

Implementation variation and fidelity in an inquiry science program: An analysis of GLOBE data reporting patterns
We examined associations among teachers’ responses to survey items to patterns in GLOBE data reporting to develop hypotheses about important contextual factors related to program implementation. Implications for the study…

Rewrite Systems for Symbolic Evaluation of C-like Preprocessing
We present convergent rewrite systems over conditional values that can interact with macro expansion and evaluation and transform them into Boolean expressions.
