Can people come to remember an event as being more traumatic than they initially experienced? Participants watched a highly structured and emotionally disturbing film depicting a car accident in which five people, including a baby, are killed. We broke the film down into a series of short clips; some of which we removed. Later, we tested participants' memory for what they had and had not seen. ...

This paper reports on a UK ESRC-funded project studying representations of practice, in video clips and voice annotations, for professional collaborative learning in distributed online environments. The project ran two main studies with learning technology professionals. The key results emerging from this work are that different kinds of video clips were found to offer support for professional ...

This paper presents a system called MusicCommentator that suggests possible comments on appropriate temporal positions in a musical audio clip. In an online video sharing service, many users can provide free-form text comments for temporal events occurring in clips not for entire clips. To emulate the commenting behavior of users, we propose a joint probabilistic model of audio signals and comm...

In this thesis, I designed a system for augmenting a space with linked audio. Using this system, individuals can associate audio clips with a location in real-world space. When an individual using the system passes through this augmented space, he or she can hear the audio clips that have been left by traveling through the associated locations. Furthermore, audio clips in the environment can be...

Axon formation is a hallmark of initial neuronal polarization. This process is thought to be regulated by enhanced microtubule stability in the subsequent axon and changes in actin dynamics in the future axonal growth cone. Here, we show that the microtubule end-binding proteins cytoplasmic linker protein (CLIP)-115 and CLIP-170 were enriched in the axonal growth cone and extended into the acti...

Scissoring of the cerebral aneurysm clip blades is a rare but potentially devastating complication of clipping surgery and results in aneurysm neck injury inducing rupture and/or cerebral infarction. Scissoring has been reported using titanium straight clips. Here we present two unusual cases of crossing of the blades of titanium bayonet clips by a scissors-like mechanism during surgery. The pr...

Virtual environments have been frequently used for training and skill improvement. However, do real and virtual worlds engage the same brain states in human perceivers? We measured brain activity using functional magnetic resonance imaging (fMRI) while adults watched movie and cartoon clips, simulating real and virtual visual worlds, respectively. Relative to baselines using random static image...
