TL;DR: The results show that both cognitively and visually demanding tasks interfere with the maintenance of a correct situation model in memory.
Abstract: For safe driving it is necessary that the drivers perceive the relevant objects of a situation, comprehend the meaning of these objects to form a holistic understanding of the current situation, and predict the future development of the situation. A concept that aims to describe and integrate these different cognitive processes is situation awareness, for example [1]. According to this concept it is assumed that a mental representation is constructed, maintained, and updated while driving. Attentional and working memory (WM) resources are involved in these processes. If secondary tasks performed while driving impose significant load on visual attention and WM, then one can expect that situation awareness is impaired. We investigated these predictions in 2 experiments. The results show that both cognitively and visually demanding tasks interfere with the maintenance of a correct situation model in memory. Visually demanding tasks do not always seem to interfere with visual attention processes in ways that lead to degraded situation awareness.

TL;DR: An overview of ARINC Report 811, Commercial Aircraft Information Security Concepts of Operation and Process Framework is provided, which describes a three-step risk-based information security process framework that considers existing airline operations and the organizational impact associated with the introduction of new aircraft information security procedures.
Abstract: In today's highly competitive air travel market, there is a growing demand among commercial airlines for on-aircraft systems, applications, and services that reduce airline operating costs, increase revenue opportunities, and improve the passenger experience. Systems such as Electronic Flight Bag (EFB) will improve efficiency of pre-flight and post-flight procedures and in-flight decision support. Enhanced communication, navigation, and surveillance systems will improve routing efficiency and situational awareness. Advanced maintenance systems will improve prognostics, diagnostics, and scheduling of maintenance actions. New cabin applications will enhance passenger services, such as buy-on-board programs and flight re-booking; passenger entertainment, including live audio and video; and passenger communications, such as in-flight cellular service and broadband Internet access for e-mail and web browsing. While many of these "new" aircraft functions may appear routine to users of the Internet, the inter-networking that is required both on and off the aircraft poses significant technical and operational challenges for airlines and their suppliers. Aircraft information security is one of the key challenges. This paper provides an overview of ARINC Report 811, Commercial Aircraft Information Security Concepts of Operation and Process Framework [1]. ARINC Report 811 was developed by airline and industry participants of the Airlines Electronic Engineering Committee (AEEC) Aircraft Information Security (SEC) Subcommittee, and it was adopted by the airline members of the AEEC in October 2005.

TL;DR: An approach using information extraction, topic and event identification and its application in a case study indicates that despite the ill-formed, variable quality and conversational nature of forum posts a degree of coherent event information can be acquired.
Abstract: With the recent exponential growth in the use of public forums for communication and sharing of information, Emergency Response organisations are realising that there is a potential to exploit these forums to extract information to improve the overall awareness of the events that occur during an emergency. This paper describes an approach using information extraction, topic and event identification and its application in a case study. The results indicate that despite the ill-formed, variable quality and conversational nature of forum posts a degree of coherent event information can be acquired.

TL;DR: The situational awareness model can provide a reference for designing new cockpit display interfaces and help reducing human errors and predicting changes of situation awareness for pilot operating with different display interface and tasks.
Abstract: To predict changes of situation awareness (SA) for pilot operating with different display interfaces and tasks, a qualitative analysis and quantitative calculation joint SA model was proposed Based on the situational awareness model according to the attention allocation built previously, the pilot cognitive process for the situation elements was analyzed according to the ACT-R (Adaptive Control of Thought, Rational) theory, which explained how the SA was produced To verify the validity of this model, 28 subjects performed an instrument supervision task under different experiment conditions Situation Awareness Global Assessment Technique (SAGAT), 10-dimensional Situational Awareness Rating Technique (10-D SART), performance measure and eye movement measure were adopted for evaluating SAs under different conditions Statistical analysis demonstrated that the changing trend of SA calculated by this model was highly correlated with the experimental results Therefore the situational awareness model can provide a reference for designing new cockpit display interfaces and help reducing human errors
