The literature agrees that the major threat to IS security is constituted by careless employees. Therefore, effective IS security requires that users are not only aware of, but also comply with organizations’ IS security policies and procedures. To address this important concern, different IS security awareness, education and enforcement approaches have been proposed. Prior research on IS secur...

Teams performing physical tasks must often be distributed in space, and are often organized hierarchically. This means that systems to support collaboration between members must account for the asymmetry in physical environment, organizational roles, and available technology. Using urban search and rescue as an example, we first describe the factors that cause this asymmetry. We then discuss th...

In hierarchical planning, landmarks are abstract tasks the decomposition of which are mandatory when trying to find a solution to a given problem. In this paper, we present novel domain-independent strategies that exploit landmark information to speed up the planning process. The empirical evaluation shows that the landmark-aware strategies outperform established search strategies for hierarchi...

In a controlled experiment on the effects of frequent and local digital annotations, 137 volunteers covered an online course at 3 conditions: no/free/question-based electronic annotations. Results show no difference in performance between groups. However, analyses conducted within treatments suggest positive impacts on performance when annotation rates are taken into consideration, and coupled ...

Learner’s self-awareness of the breadth and depth of their expertise is crucial for self-regulated learning. Further, of learners report self-knowledge assessments to teaching systems, this can be used to adapt teaching to them. These reasons make it valuable to enable learners to quickly and easily create such models and to improve them. Following the trend to open these models to learners, we...

The construct of situation awareness (SA) has become a core theme within the human factors (HF) research community. Consequently, there have been numerous attempts to develop reliable and valid measures of SA but there is a lack of techniques developed specifically for the assessment of SA in command, control, communication, computers and intelligence (C4i) environments. During the design, deve...

The availability of applications able to exploit multi-device environments is steadily increasing. Rather than using all devices in the same way, users tend to assign different roles to devices due to the capabilities needed, such as computational power and screen size. Researchers and developers have started to introduce various techniques and tools to support managing applications across mult...
