This research project explores the effectiveness of an auditory display (AD) prototype for the sonification of perceived internet e-waste of CO 2 emissions to a small user group within their office context. To date, methods do not exist for the reporting of e-waste to users of personal computing while they perform simple internet enquiries. Underpinning the theoretical development of this project is a focus on AD guided by a soundscape theory, and on approaches to sonification to convey subtle, unobtrusive, and useful information. Evaluation of the prototype takes place as a field study in an office context. The following paper gives an account of the design and development of the AD prototype and its respective sonification, the design methodology employed and the research findings, and concludes with recommendations for further exploration of the balance between ambient and salient information.

Although self-injury is a relatively common behaviour, the meanings of such behaviour for those who engage in it remain poorly understood. Here we report findings from an exploratory study of how contributors negotiate self-injury in the context of online discussion forums. Data come from forums identified through use of internet search engines. Contributors’ postings to discussion threads on these forums were analysed using discourse analysis. Within discussion threads, contributors construct self-injury as positive, either in itself or in certain forms, rather than negative or harmful behaviour. These constructions present challenges for health promotion initiatives. More research is needed into how descriptions of self-injury are bound up with negotiations of individual identities.
