The exact structure of large, biologically
interesting molecules such as proteins is very
important for the functions these molecules fulfill.
To increase our understanding of the relationship
between structure and function, and to enhance the
predictive power of theoretical models, the
structures of a few small model systems have been
determined very precisely. Each of these model
systems is closely related to important structural
elements in proteins or DNA. The structure
determination itself takes place by irradiating the
molecules with UV laserlight and detecting which
colors are absorbed...

Frontline crisis response is challenging. Emergency responders, soldiers, and humanitarian aid workers all operate at the frontlines of threatening, uncertain crisis situations on a daily basis. Under intense pressure, they need to make a range of difficult decisions: to follow preexisting plans or improvise; to abide by top-down instructions or take discretionary actions; to get emotionally involved or keep a rational distance? These dilemmas define their work but, until now, have not been subjected to systematic investigation. This book conducts in-depth studies of eleven such dilemmas by...
