Pick-n-mix approaches to technology supply : XML as a standard “glue” linking universalised locals

We report on our experiences in a participatory design project to develop ICTs in a hospital ward working with deliberate self-harm patients. This project involves the creation and constant re-creation of sociotechnical ensembles in which XML-related technologies may come to play vital roles. The importance of these technologies arises from the aim underlying the project of creating systems that are shaped in locally meaningful ways but reach beyond their immediate context to gain wider importance. We argue that XML is well placed to play the role of "glue" that binds multiple such systems together. We analyse the implications of localised systems development for technology supply and argue that inscriptions that are evident in XML-related standards are and will be very important for the uptake of XML technologies

Healthcare technologies and professional vision

This paper presents some details from an observational evaluation of a computer assisted detection tool in mammography. The use of the tool, its strengths and weaknesses, are documented and its impact on reader's 'professional vision' (Goodwin 1994) considered. The paper suggests issues for the design, use and, importantly, evaluation of new technologies in everyday medical work, pointing to general issues concerning trust – users’ perception of the dependability of the evidence generated by such tools and suggesting that evaluations require an emphasis on the complex issue of what technologies afford their users in everyday work

Abstractions, accounts and grid usability

The vision of the Grid is one of seamless, virtual and constantly changing resources where users need not concern themselves about details, such as exactly where an application is running or where their data is being stored. However, seamless and virtual often imply a lack of control that users may be wary of, or even opposed to. Drawing upon our studies of HCI and of collaborative work, this paper examines whether the Grid development community should be taking this vision literally and argues for the need for accountability of systems ‘in interaction’. We give examples of an alternative approach that seeks to provide ways in which administrators, technical support and user communities can make sense of the behaviour of the complex socio-technical ensembles that are the reality of Grids

Authority as an interactional achievement: Exploring Deference to Smart Devices in hospital-based resuscitation

Over the years, healthcare has been an important domain for CSCW research. One significant theme carried through this body of work concerns how hospital workers coordinate their work both spatially and temporally. Much has been made of the coordinative roles played by the natural rhythms present in hospital life, and by webs of mundane artefacts such as whiteboards, post-it notes and medical records. This paper draws upon the coordinating role of rhythms and artefacts to explore the nested rhythms of the Cardio-Pulmonary Resuscitation (CPR) protocol conducted to restore the proper heart rhythm in a patient who has suffered a cardiac arrest. We are interested in how the teams delivering CPR use various ‘smart’ assistive devices. The devices contain encoded versions of the CPR protocol and are able to sense (in a limited way) the situation in order to give instructions or feedback to the team. Using an approach informed by ethnomethodology and conversation analysis (EM/CA) we analysed video of trainee nurses using these devices as they delivered CPR in dramatized training scenarios. This analysis helped us to understand concepts such as autonomy and authority as interactional accomplishments, thus filling a gap in CSCW literature, which often glosses over how authority is formed and how it is exercised in medical teams. It also helps us consider how to respond to devices that are becoming more active in that they are being increasingly imbued with the ability to sense, discriminate and direct activity in medical settings
