Using Visual Representations as Boundary Objects to Resolve Conflict in Collaborative Model-Building Approaches

Collaborative knowledge building with shared video representations

Online video has become established as a fundamental part of the fabric of the web; widely used by people for information sharing, learning and entertainment. We report results from a design study that explored how people interact to create shared multi-path video representations in a social video environment. The participants created multiple versions of a video by providing alternative and in...

Reconstructing representations of dynamic visual objects in early visual cortex.

As raw sensory data are partial, our visual system extensively fills in missing details, creating enriched percepts based on incomplete bottom-up information. Despite evidence for internally generated representations at early stages of cortical processing, it is not known whether these representations include missing information of dynamically transforming objects. Long-range apparent motion (A...

Local Understandings: Boundary Objects in High Conflict Settings

This study explores the processes and characteristics that comprise successful boundary objects. Through a longitudinal exploration of an extensive qualitative database, we identify characteristics of both successful boundary objects and the processes by which they are created. It further discusses the life cycle of a boundary object, and the challenges associated with the use of boundary objec...

Using single-cell multiple omics approaches to resolve tumor heterogeneity

It has become increasingly clear that both normal and cancer tissues are composed of heterogeneous populations. Genetic variation can be attributed to the downstream effects of inherited mutations, environmental factors, or inaccurately resolved errors in transcription and replication. When lesions occur in regions that confer a proliferative advantage, it can support clonal expansion, subclona...
