When collaborating across distances, situation awareness is mediated by technology. There are few guidelines to help system analysts design systems or applications that support the ...

There has been much activity over the past two decades in developing conceptual models under the titles of data fusion and situation awareness. In this paper we will explore the two most popular models and show how they complement each other in developing an overall framework for situation awareness. We will also demonstrate how this framework has been applied to a sample “monitoring” problem.

Infinite hierarchies of awareness and beliefs arise in games with unawareness, similarly to belief hierarchies in standard games. A natural question is whether each hierarchy describes the player’s awareness of the hierarchies of other players and beliefs over these, or whether the reasoning can continue indefinitely. This paper constructs the universal type structure with unawareness where eac...

We first describe the theoretical framework we are using to analyze the role of visual information in physical collaboration. Then, we present ...

In this paper we argue for an experientially grounded view of IT professionals’ ethical formation and support.

To this end, we present a Model of Ethical IT, which is based on an examina...

The proliferation of mobile devices, and the migration of the information access paradigm to mobile platforms, motivate studies of power consumption behaviors with the purpose of increasing the device battery life. The aim of this work is to profile the power consumption of a Samsung Galaxy I7500 and a Samsung Nexus S, in order to understand how such feature has evolved over the years. We perfo...

This study investigated whether the negative effect of complexity on artificial grammar learning could be compensated by adding semantics. Participants were exposed to exemplars from a simple or a complex finite state grammar presented with or without a semantic reference field. As expected, performance on a grammaticality judgment test was higher for the simple grammar than for the complex gra...

The non-technical skills of situational awareness and the formation of effective interpersonal relationships are essential to enhance surgical outcomes. However, most scrub practitioners demonstrate only tacit awareness of these skills and develop such qualities on an informal basis. Application of non-technical skills may be assessed formally, using a structured framework, to transform normati...
