This research explores the ability of grade 2 students to engage in productive discussion about the state of their knowledge building using group-level feedback tools to support their metadiscourse. Two aspects of knowledge work were common to the comparison and experimental classes: BKnowledge Building talk^ (KB talk) involving teacher-student discussions and the use of Knowledge Forum, an onl...

(1) For every macro instruction I and for every integer location a holds card(if a = 0 then I; Goto(insloc(0)) else (StopSCMFSA)) = card I +6. (2) For every macro instruction I and for every integer location a holds card(if a > 0 then I; Goto(insloc(0)) else (StopSCMFSA)) = card I +6. Let a be an integer location and let I be a macro instruction. The functor while a = 0 do I yields a macro inst...

In this study, we propose dynamic prioritization of image macro-blocks for Wireless Multimedia Sensor Networks (WMSN). An encoding scheme is employed at the source node by labeling the blocks as “important” or “not-important” based on the information they contain. We introduce a set of novel priority measures to weigh importance of macro-blocks using their intrinsic properties. Experimental res...

PURPOSE This study explored contributions that patients' companions (seizure witnesses) make to interactions in the seizure clinic and whether the nature of the companions' interactional contributions can help with the differentiation of epilepsy and psychogenic nonepileptic seizures (PNES). METHODS Conversation analysis methods were used to examine video recordings and transcripts of neurolo...

We conducted twenty semi-structured interviews with university professors from eight states in the US about their collaborations via computer mediated communication. Our thematic analysis of verbatim transcripts uncovered four dialectical tensions (an interplay of opposing and contradictory forces typically resolved through communication) in such interactions: relational connection and personal...

This study examines the effect of smiling on GOAT fronting, a sound change common to many varieties of American English. The data are audiovisual recordings of ten speakers of American English recorded in dyadic conversations in an interactional sociophonetics laboratory. We applied an existing computer vision algorithm for smile detection to the video recordings to identify smiling intervals. ...
