For successful written communication, the writer not only must engage the readers’ attention but also must sustain their interest till the end whatever the length of the communication. The subject of the communication, the information or the propositional content alone, cannot hold the reader’s attention for long. A writer’s success depends not only on what is being conveyed but also on how wel...

The ability to sustain attention influences different domains including cognitive, motor, and communicative behavior. Previous research has demonstrated how an infant's parent can influence sustained attention. The purpose of our study was to expose infants systematically to both sensitive and redirective patterns of behavior to examine how unfamiliar individuals could influence attention. Resu...

Ninety-three 1%year-olds were tested with measures thought to tap information processing, sustained attention, executive function, and intelligence. The visual fixation patterns and home rearing conditions of these adolescents, born preterm, had been observed in early infancy. Infant fixation durations were negatively associated with information processing, executive function, and intelligence ...

Previous computer conferencing research has been concerned with the organizational, technical, social, and motivational factors that support and sustain online interaction. This article studies online interaction from a different perspective. Rather than analyze the processes that sustain discourse, the following research examines how and why discussions shut down. A computer simulation of asyn...

Tissue engineering promises to replace and repair body organs but has largely been overlooked for artistic purposes. In the last 6 years, the authors have grown tissue sculptures, asemi-living objects,o by culturing cells on arti® cial scaffolds. The goal of this work is to culture and sustain for long periods tissue constructs of varying geometrical complexity and size, and by that process to ...

Based on human visual attention mechanism and texture visual perception, this paper proposes a method for man-made object detection by extracting texture and geometry structure features. Followed by clustering the texture feature, geometry structure feature is obtained to realize final detection. Then a man-made object detection scheme is designed, by which typical man-made objects in complex n...

This paper describes an algorithm, which performs monophonic music transcription. A pitch tracker calculates the fundamental frequency of the signal from the autocorrelation function. A continuity-restoration block takes the extracted pitch and determines the score corresponding to the original performance. The signal envelope analysis completes the transcription system, calculating attack-sust...

Research-based calls for science education reform emphasize that, for inquiry and deep learning to occur, teachers must attend to the substance of students’ ideas, which must play a prominent role in class. Using classroom video and teacher interviews, we illustrate two different ways of attending to students’ ideas, both of which sustain students’ sensemaking. These two different kinds of atte...
