OBJECTIVE The purpose of this article is to present and expand on current theories and measurement techniques for assessing team workload. BACKGROUND To date, little research has been conducted on the workload experienced by teams. A validated theory describing team workload, which includes an account of its relation to individual workload, has not been articulated. METHOD The authors revie...

backgrounds: situation awareness is an important factor in industrial accidents. improving situation awareness may help to prevent occupational accidents. determination of factors influencing situation awareness will help to plan and take measures for betterment of working condition and development of a safer workplace. in this study, we examined the role of work overload and job stress in pred...

To contribute to systems that reason about human attention, our work empirically demonstrates how a user’s mental workload changes during task execution. We conducted a study where users performed interactive, hierarchical tasks while mental workload was measured through the use of pupil size. Results show that (i) different types of subtasks impose different mental workload, (ii) workload decr...

With the development of search engines, more and more web crawlers are used to gather web pages. The rising crawling traffic has brought the concern that crawlers may impact web sites. On the other hand, more efficient crawling strategy is required for the coverage and freshness of search engine index. In this paper, crawlers of several major search engines are analyzed using one six-months acc...

Two basic approaches are taken when modeling workloads in simulation-based performance evaluation of parallel job scheduling algorithms: (1) a carefully reconstructed trace from a real supercomputer can provide a very realistic job stream, or (2) a exible synthetic model that attempts to capture the behavior of observed workloads can be devised. Both approaches require that accurate statistical...

BACKGROUND Research on resident workloads has focused primarily on the quantity of hours worked, rather than the content of those hours or the variability among residents. We hypothesize that there are statistically significant variations in resident workloads and better understanding of workload intensity could improve resident education. METHODS The Stanford Children's Health research datab...

conclusions the results showed that the heat stress increased by increasing air velocity and humidity in both groups. the air velocity with high humidity can be considered as a positive factor in the occurrence of heat strain. therefore, the incidence of heat stress decreases with the increase of humidity and reduction of air velocity or with increase of air velocity and reduction of humidity i...

The mental workload imposed by systems is important to their operation and usability. Consequently, researchers and practitioners need reliable, valid, and easy-to-administer methods for measuring mental workload. The ratio of perceived time to clock time appears to be such a method, yet mental workload has multiple dimensions of which the perceived time ratio has mainly been linked to the task...
