This is a brief review, in relatively nontechnical terms, of recent rather technical advances in the theory of random field geometry. These advances have provided a collection of explicit new formulae describing mean values of a variety of geometric characteristics of excursion sets of random fields, such as their volume, surface area and Euler characteristics. What is particularly important in...

actors working in global health often portray it as an enterprise grounded in principled concerns, advanced by individuals and organizations who draw on scientific evidence to pursue health equity. this portrait is incomplete. it is also a field of power relations—a social arena in which actors claim and draw on expertise and moral authority to gain influence and pursue career, organizational a...
