problems generated by these pollutants to be more and more acute as time goes by. This book, edited by Miller and Berg, is a compilation of the proceedings of a conference held at the University of Rochester to collect and consider such scattered accumulated data. The chapters represent individual contributions by the authors at the conference. Each chapter contains references and a summarized ...

We study a discrete-time resource flow in Zd, where wealthier vertices attract the resources of their less rich neighbors. For any translation-invariant probability distribution of initial resource quantities, we prove that the flow at each vertex terminates after finitely many steps. This answers (a generalized version of) a question posed by Van den Berg and Meester in 1991. The proof uses th...

Abstract: Two concepts of symmetry for the distributions of positive random variables Y are log-symmetry (symmetry of the distribution of log Y ) and R-symmetry ([7]). In this paper, we characterise the distributions that have both properties, which we call doubly symmetric. It turns out that doubly symmetric distributions constitute a subset of those distributions that are moment-equivalent to...

Diversity, evolution, and epidemiology of HIV are directly relevant to HIV transmission and pathogenesis; hence, they play a key role in antiretroviral treatment and vaccine design. Global HIV whole-genome sequencing would provide a treasure chest of data to answer many questions still open in these fields. An article by Berg et al. in this issue of theJournal of Clinical Microbiologydescribes ...

A little more than a decade ago, Nathan Berg asked the question why behavioral economics had not yet inspired a reorientation of normative economics. Given the ever rising interest in the new, psychologically informed economics, the present paper will outline the way reasoning about the normative implications of behavioral economics has developed since Berg raised the issue. We argue that behav...
