BACKGROUND Few studies have investigated the independent associations of lifestyle behaviors (diet, physical activity, sleep, and screen time) and body weight status with academic achievement. Even fewer have investigated the combined effect of these behaviors on academic achievement. We hypothesize that the combined effect of these behaviors will have a higher impact on academic achievement th...

This writing task was found to lead to significantly improved health outcomes in healthy participants. Health was enhanced in 4 outcome types--reported physical health, psychological well-being, physiological functioning, and general functioning--but health behaviors...

This study asks the question: Can a robot learn to identify object-surface pairs that are useful for trace-making and, thus, facilitate writing? Writing is an important skill that humans use everyday and future household robots may have to master in order to be useful. Specifically, our robot performed scribbling behaviors with different objects on different surfaces and monitored which objects...

For instance, this challenge is modeling of computer supported collaborative writing. highlighted by the situated actions paradigm, which emThe aim of this dynamic modeling approach is to capture phasizes the contingent nature of the organization and the structure of user behavior as they interact with a evolution ...

Character behaviors in computer role-playing games have a significant impact on game-play, but are often difficult for game authors to implement and adapt. We present a behavior model that requires no manual script writing. In this model, behaviors can be interrupted and resumed, they can transition to other behaviors depending on game events, and they can be chosen based on motivations. We hav...
