Overactivity is a frequently used term in chronic pain literature. It refers to the phenomenon whereby individuals engage in activity in a way that significantly exacerbates pain, resulting in periods of incapacity. Overactivity, as a construct, has been derived solely from patients' self-reports, raising concerns about the legitimacy of the construct. Self-reported overactivity reflects an ind...

Computation is now packaged in a variety of devices. Smaller and lighter laptop/notebooks, as powerful as conventional personal computers, free us from the confines of the single desk. Specialized devices such as handheld personal organizers are portable enough to be with us all the time. Wireless technology allows devices to be fully interconnected with the electronic world. Cameras and VCRs a...

Currently handheld and palmtop computers are widely used for personal information management. In the near future they will also be used to access enterprise data. There are however, numerous technical challenges in enabling an end-to-end system that provides enterprise data access from mobile computers. The challenges include heterogeneity, various resource constraints, scalability, and securit...

Recent research in the area of Computer Support for Collaborative Learning (CSCL) suggests that collaborative learning activities give learners new insights and perspectives in their learning process. In order to support collaboration, learners need appropriate tools to share, exchange and argument their ideas. The use of wireless networked handheld computers in education is rapidly increasing,...

The typical user environment load spectrum varies significantly between different electronic applications but changes in temperature are involved in nearly all of them. Owing to the increasing number of integrated high-performance functions, smartphones and handheld computers, for example, can experience significant changes in temperature during normal operation. The changes in temperature are ...

INTRODUCTION Portable handheld computers and electronic data management systems have been used for national surveys in many high-income countries, however their use in developing countries has been challenging due to varying geographical, economic, climatic, political and cultural environments. In order to monitor and measure global adult tobacco use, the World Health Organization and the US Ce...

Survey agencies in the United States continue to move many map-based surveys from paper to handheld computers. With large highly diverse workforces, it is necessary to test software with a diverse population. The present work examines the performance of participants grouped by their level of spatial visualization. The participants were tested in either the field or in a fully immersive virtual ...

Effective emotion regulation may promote resilience and preschool classroom adjustment by supporting adaptive peer interactions and engagement in learning activities. We investigated how hypothalamus-pituitary-adrenal axis (HPA) regulation, cardiac reactivity, and classroom emotion displays related to adjustment among low-income preschoolers attending Head Start. A total of 62 four-year-olds co...

The rise in the ubiquity of wireless internet access and handheld computing devices has opened several avenues for Location-Based and Location-Aware applications. Our work introduces an adaptation of a notification system based on Location-centric events and features. Real-time information can be used in order to increase a users’ comprehension of his environment. Our prototype system, seeVT, p...

This article examines several new and exciting communication technologies. Many of the technologies were developed by the entertainment industry; however, other industries are adopting and modifying them for their own needs. These new technologies allow people to collaborate across distance and time and to learn in simulated work contexts. The article explores the potential utility of these tec...
