Distributed Cognition is growing in popularity as a way of reasoning about group working and the design of artefacts within work systems. DiCoT (Distributed Cognition for Teamwork) is a methodology and representational system we are developing to support distributed cognition analysis of small team working. It draws on ideas from Contextual Design, but(More)
Processes that enable an effective response to unexpected events and vulnerabilities that lie outside the scope of formal procedures can be described as being resilient. There are many such descriptions of resilience within and across different domains. Comparison and generalisation is difficult because resilience is not a component of a system and should(More)
Grounded Theory (GT) is used within HCI research, but nuances and more modern interpretations of the method are rarely discussed. This paper has two intentions: to offer guidance on practical issues when applying GT, and to clarify the space of methodological possibilities. We describe an extended GT study on understanding why practitioners choose(More)
Renal cell carcinoma is a relatively uncommon tumour with a widely varying prognosis depending on several tumour and clinical factors. This review discusses these factors and critically appraises their value both as individual markers and when they are incorporated into scoring systems/models or algorithms. Disease stage (assessed pathologically and/or(More)
Emergency medical dispatch (EMD) is typically a team activity, requiring fluid coordination and communication between team members. Such working situations have often been described in terms of distributed cognition (DC), a framework for understanding team working. DC takes account of factors such as shared representations and artefacts to support reasoning(More)
Much of the knowledge used within an XP team is tacit, i.e. it is hidden and intangible. Two tangible artefacts that carry information about the team’s work are the index cards which capture stories and tasks to be implemented and the wall where they are displayed (which we refer to as the ‘Wall’). It is widely acknowledged that these are key elements(More)
In this paper we describe results from an exploratory study observing infusion pump use in practice. From 31 observations of pump programming we note 10 low-level disturbances, which we conceptualise in terms of unremarkable error. This data supports a view that well performing systems cope with error as part of their normal work. Users are able to recover(More)
That version may differ from the current one. ABSTRACT There is a wealth of user-centred evaluation methods (UEMs) to support the analyst in assessing interactive systems. Many of these support detailed aspects of use – for example: Is the feedback helpful? Are labels appropriate? Is the task structure optimal? Few UEMs encourage the analyst to step back(More)
The mouse mutant Doublefoot (Dbf) shows preaxial polydactyly with 6-9 triphalangeal digits in all four limbs and additional abnormalities including a broadened skull, hydrocephalus, and a thickened, kinked tail. The autopod undergoes a characteristic expansion between late embryonic day (E) 10.5 and E11.5, following the onset of ectopic Indian hedgehog(More)
