In this paper we discuss the Network Analysis Visualization (NAV) project, a tool for investigating high level network events. Monitoring network activity has been a critical task for administrators since networks were first introduced, both for maintaining system security and tracking resource utilization. Traditionally, the tools used by both enterprise(More)
PhotoTalk is an application for a mobile device that allows people with aphasia to capture and manage digital photographs to support face-to-face communication. Unlike any other augmentative and alternative communication device for people with aphasia, PhotoTalk focuses solely on image capture and organization and is designed to be used independently. Our(More)
Individual yeast cells display a finite replicative capacity. LAG1 was identified as a gene that is differentially expressed during the yeast replicative life span and was shown to play a role in determining yeast longevity. This gene is not essential, but simultaneous deletion of LAG1 and its close homologue LAC1 is lethal. Lag1p and Lac1p have been found(More)

Current methods of playlist creation and maintenance do not support user needs, especially in a mobile context. Furthermore, they do not scale: studies show that users with large mp3 collections have abandoned the concept of playlists. To remedy the usability problems associated with playlist creation and navigation - in particular, reliance on visual(More)
We report on an exploratory study we conducted to investigate what kind of diagrammatic tool support, if any, is desired by programmers. The study involved 19 professional programmers working at three different companies. We found that the study participants desire a wide range of information content in diagrams, which would change depending upon the(More)

Our study explores the use of tinkering strategies across genders in undergraduate students of Computer Science. We present a definition and a framework for tinkering as it applies to this context, and use these to investigate how students across genders tinker with hardware and software. Our goal is to examine gender-based differences in tinkering(More)
