Observing briefly trained, non-certified interpreters at work: Risk Analysis

Observing a quantum Maxwell demon at work.

In apparent contradiction to the laws of thermodynamics, Maxwell's demon is able to cyclically extract work from a system in contact with a thermal bath, exploiting the information about its microstate. The resolution of this paradox required the insight that an intimate relationship exists between information and thermodynamics. Here, we realize a Maxwell demon experiment that tracks the state...

Observing Cognitive Work in Offices

The information revolution has a deep impact on office work. To create better environments for cognitive workers, we designed two observation tools recording office activity. The Subcam (subjective camera) is a miniature, wearable, wide angle video camera, clipped on a pair of glasses ; it records individual activity from a subjective point of view, wherever the user goes. The Offsat (office sa...

Non-work at Work, Unemployment and Labor Productivity

We use the American Time Use Survey (ATUS) 2003-2012 to estimate time spent in non-work on the job. Non-work is substantial and varies positively with local unemployment. Time spent in non-work conditional on any positive amount rises, while the fraction of workers reporting positive values declines with unemployment. Both effects are economically important, and are consistent with a model in w...

Cultural Capital at Work: How Cognitive and Non-Cognitive Skills Are Taught, Trained and Rewarded in a Chinese Technical College

Certified Memory Usage Analysis

We present a certified algorithm for resource usage analysis, applicable to languages in the style of Java byte code. The algorithm verifies that a program executes in bounded memory. The algorithm is destined to be used in the development process of applets and for enhanced byte code verification on embedded devices. We have therefore aimed at a low-complexity algorithm derived from a loop det...
