We report on a study with 65 middle-school students who learned about the concept of diffusion through observation. We manipulated two factors: the number of observers, solo vs. dyad, and the type of video students observed, tutorial dialogue vs. monologue. Our findings show that dyad observers learn significantly better than solo observers, and that for certain types of questions, observing di...

This research examines the impact of various factors on the use of IT in clinical practice, prescriptions, and patient information. This was done using a national sample of 3425 physicians who worked in a solo or group practice in the United States. Besides the extent of use of electronic medical records by physicians and number of physicians in practice, none of the other factors consistently ...

Solo is a cognitive assistive device which provides support in remembering when to perform tasks, executing the steps in a task, and recovering from unexpected events. The system includes an interface for clients to receive reminders, an interface for caregivers to enter information about the client’s scheduled tasks, and a Cognition Manager which provides reminders and task guidance at appropr...

Objective: Comparison of program defects caused by programmer pairs and solo developers. Design: Analysis of programs developed during two counter balanced experiments. Setting: Programming lab at University. Experimental Units: 42 programs developed by computer science students participating in an extreme programming lab course. Main Outcome Measures: Programmer pairs make as many algorithmic ...

IMPROVISATION Kjell Bäckman Informatics Department University West Trollhättan, Sweden ABSTRACT Recent work by the author has revealed the need for an automatic fitness function in the evolutionary algorithm for generation of jazz solos. A computer based automatic fitness function enables greater populations and a great number of generations within a manageable time. This paper describes how th...

237 participants listened to a 37 second extract of original music for solo piano, and were asked to retrospectively verbally estimate elapsed duration. Differences were found for age (mean estimate for ages 5-8: 76.11 seconds, ages 9-10: 66.38, 11-13: 54.88 seconds, ages 14 to adult: 65.17 seconds) and a correlation found between adult age and estimate. Estimates were found to be significantly...

This article is concerned with the F0 tracking in monodic instrument solo recordings. Due to reverberation, the observed signal is rather polyphonic and single-F0 tracking techniques often give unsatisfying results. The proposed method is based on multiple-F0 estimation and makes use of the a priori knowledge that the observed spectrum is generated by a single monodic instrument. The predominan...
