Contemporary in its style and preoccupations, 'Radio Inside' expresses a particular kind of
Meaning of the Interval
'Meaning of the Interval' is a reflection on openings or intervals that the Japanese call 'ma,' and how they apply to any number of activities in Japan.

Images from Japanese public life, ceremonies, and performances are juxtaposed and layered. Sometimes a split-screen approach is used. Scenes include a Butoh dance performance,
'Hart Island' tells the story of the uses of Hart Island, which has served as an internment locale for homeless men, drug addicts, and prisoners, and as a defense training ground. The work alternates images of Hart Island and the activity there with visual text describing its history. Close-up views of men unloading boxes and digging holes are seen. As the text gradually makes clear, these men are inmates from Rikers Island prison on a work crew. Their job is to bury the unclaimed dead (includin

Assessing the Biological Weapons and Bioterrorism Threat
BIOSECURITY FOR A NEW ERA Lecture Series Biological weapons (BW) have been a significant national security preoccupation for nearly 15 years. The events of September 11 and the anthrax attacks that followed have magnified these concerns by orders of magnitude while shifting the context almost entirely to "bioterrorism." Over the past four years, the federal government has spent nearly $30 billion to counter the anticipated threat. Strangely, these responses took place in the absence of virtuall
