This article addresses the under-theorization of visual techniques for social science research applications through the cultural-historical activity theory (CHAT). The "problem" of "the visual" in research is given an ontological framing by highlighting the ways in which the use of visual techniques as research tools--designed to elicit participant responses--has a bearing upon the types of data that are produced: the "how" to some degree shapes the "what" of research output. CHAT, by drawing our attention to the ways in which the artefacts we use to mediate researcher-participant relationship (our visual research tools) also affects them, alerts us to the meanings that we (inadvertently, reflexively or even deliberately) create in the research process. Three different kinds of visual techniques are explored according to a CHAT-informed typology: diagrams as a means of eliciting technical information, drawings as a means of eliciting interpretations and judgements and fictional characters as a means of eliciting personal identification. In each case, the ontological consequences of the choice of visual technique for the insight produced are discussed to explore the value of CHAT as one approach to deepening our understanding and appreciation of the value of "the visual" in research.

The use of graphic representations of experience and the social environment in the data collection process is an emerging approach. The terms diagramming, mapping and drawing are often used interchangeably, with no common interdisciplinary understanding of what they mean. The lack of a unifying terminology has resulted in simultaneous but separate developments undermining a more coherent approach to this emergent method. By defining what a diagram is and examining where diagramming fits amongst other data collection approaches, this paper proposes the term diagrammatic elicitation to refer to the use of diagrams in the data collection process. Two subcategories of this approach include: (a) participant-led diagrammatic elicitation, where participants create original diagrams and (b) researcher-led diagrammatic elicitation, where the researcher draws the diagram during the data collection process for discussion or participants edit a researcher-prepared diagram. Establishing these terms will allow researchers to share best practice and developments across disciplines. [ABSTRACT FROM AUTHOR]

Background Non-drug technologies offer many benefits, but have been associated with adverse events, prompting calls for improved postmarket surveillance. There is little empirical research to guide the development of such a system. The purpose of this study was to identify optimal postmarket surveillance strategies for medical and surgical devices. Methods Qualitative methods were used for sampling, data collection and analysis. Stakeholders from Canada and the USA representing different roles and perspectives were first interviewed to identify examples and characteristics of different surveillance strategies. These stakeholders and others they recommended were then assembled at a 1-day nominal group meeting to discuss and prioritise the components of a postmarket device surveillance system, and research needed to achieve such a system. Results Consultations were held with 37 participants, and 47 participants attended the 1- day meeting. They recommended a multicomponent system including reporting by facilities, clinicians and patients, supported with some external surveillance for validation and realtime trials for high-risk devices. Many considerations were identified that constitute desirable characteristics of, and means by which to implement such a system. An overarching network was envisioned to broker linkages, establish a shared minimum dataset, and support communication and decision making. Numerous research questions were identified, which could be pursued in tandem with phased implementation of the system. Discussion These findings provide unique guidance for establishing a device safety network that is based on existing initiatives, and could be expanded and evaluated in a prospective, phased fashion as it was developed.
