Communication networks involve the transmission and reception of large volumes of data. Research indicates that network traffic volumes will continue to increase. These traffic volumes will be unprecedented and the behaviour of global information infrastructures when dealing with these data volumes is unknown. It has been tshown that complex systems (including computer networks) exhibit self-organized criticality under certain conditions. Given the possibility in such systems of a sudden and spontaneous system reset the development of techniques to inform system administrators of this behaviour could be beneficial. This article focuses on the combination of two dissimilar research concepts, namely sonification (a form of auditory display) and self-organized criticality (SOC). A system is described that sonifies in real time an information infrastructure's self-organized criticality to alert the network administrators of both normal and abnormal network traffic and operation.

This chapter treats computer networks as a cyber warfighting domain in which the maintenance of situational awareness is impaired by increasing traffic volumes and the lack of immediate sensory perception. Sonification (the use of non-speech audio for communicating information) is proposed as a viable means of monitoring a network in real time and a research agenda employing the sonification of a network's self-organized criticality within a context-aware affective computing scenario is given. The chapter views a computer network as a cyber battlespace with a particular operations spectrum and dynamics. Increasing network traffic volumes are interfering with the ability to present real-time intelligence about a network and so suggestions are made for how the context of a network might be used to help construct intelligent information infrastructures. Such a system would use affective computing principles to sonify emergent properties (such as self-organized criticality) of network traffic and behaviour to provide effective real-time situational awareness.

In 1222, Adam, bishop of Caithness, was murdered by a group of Caithness landholders. Although it appears in a fourteenth century manuscript, the Old Norse text Brenna Adams Byskups (The Burning of Bishop Adam) originated in Iceland in the 1230s. It provides a Caithness-based perspective on Adam’s death to compare with other accounts from around the world. Including a new transcription and translation of the text, this article contextualises Brenna Adams Byskups and the events of Adam’s death. At this time, the bishops of Caithness were used by the Scottish kings to promote royal authority in the territory of the jarls of Orkney and Caithness, leading to moments of violence. By comparing Brenna Adams Byskups to other accounts, Jarl Jón’s (died 1231) role in Adam’s death can be established, as can the extent of King Alexander II’s (1214–49) punishments. Adam’s murder had a significant impact on northern Scotland, consolidating Scottish royal authority in Sutherland and possibly contributing to Jarl Jón’s murder in 1231.
