We outline three challenges involved in designing external representations that promote sustainable use of natural resources. First, the task environment of sustainable resource-use is highly unstructured, and involves many uncoordinated and asynchronous actions. Following from this complex nature of the task environment, more task constraints and task interactions are involved in designing representations promoting sustainability, compared to representations that seek to make tasks easier in structured task environments, such as aircraft cockpits and control rooms. Second, external representations promoting sustainable resource-use (...) need to motivate people to make decisions that sustain resources, and persist with this behavior, even though alternate behaviors are easier and commonplace. Third, external representations promoting sustainability also need to lower the cognitive load involved in sustainability decisions. This three-tiered function (meeting complex task constraints, providing motivation, lowering cognitive load) makes such representations challenging to design. However, some early prototype designs promoting sustainable resource-use have appeared recently, primarily addressing electricity use. Analyzing these digital prototypes, we outline three design principles they share, and show how these seek to address the complexities of the sustainability problem-space (complexity of task environments, goals, and representations). We then argue that at least two further cognitive scaffolds are required for effectively promoting sustainable resource use (action scripts, deconstruction). We close with some of the limitations of this approach to promoting sustainability, and outline future work. (shrink)

In this article we study how members of an interdisciplinary research team use an online forum for communicating about their research project. We use the concepts of "community of practice" and "connectivity" to consider the online interaction within a wider question of how people from different academic traditions "do" interdisciplinarity. The online forum for this Grey and Pleasant Land project did not take off as hoped, even after a series of interventions and amendments, and we consider what the barriers were (...) and how they might be overcome. Barriers to involvement included participants' expectations of interaction and collaboration--expectation that real interaction happens elsewhere, tensions between academic discourse and forum talk norms, unfamiliarity with the technology, and different conceptions of appropriate academic discussion. We suggest that common academic practice does not prepare us well for creating interdisciplinary research communities through online collaboration tools, whereas such tools are our best bet currently for including geographically dispersed members in collaborative projects. Therefore, careful planning and competence building would be necessary if such tools are to be used in collaborative research. Suggested interventions, based on our experience, include providing a more focused forum, making technical support easily available, and setting up particular tasks or items to debate, within a preset, synchronous timeframe, focusing on issues relevant to the project at that time.
