The Memoirs of the AMS is devoted to the publication of new research in all areas of pure and applied mathematics. The Memoirs is designed particularly to publish long papers of groups of cognate papers in book form, and is under the supervision of the Editorial Committee of the AMS journal Transactions of the American Mathematical Society. All papers are peer-reviewed.

This SpringerBriefs employs a novel approach to obtain the precise asymptotic behavior at infinity of a large class of permanental sequences related to birth and death processes and autoregressive Gaussian sequences using techniques from the theory of Gaussian processes and Markov chains. The authors study alpha-permanental processes that are positive infinitely divisible processes determined by the potential density of a transient Markov process. When the Markov process is symmetric, a 1/2-permanental process is the square of a Gaussian process. Permanental processes are related by the Dynkin isomorphism theorem to the total accumulated local time of the Markov process when the potential density is symmetric, and by a generalization of the Dynkin theorem by Eisenbaum and Kaspi without requiring symmetry. Permanental processes are also related to chi square processes and loop soups. The book appeals to researchers and advanced graduate students interested in stochastic processes, infinitely divisible processes and Markov chains.

This book was first published in 2006. Written by two of the foremost researchers in the field, this book studies the local times of Markov processes by employing isomorphism theorems that relate them to certain associated Gaussian processes. It builds to this material through self-contained but harmonized 'mini-courses' on the relevant ingredients, which assume only knowledge of measure-theoretic probability. The streamlined selection of topics creates an easy entrance for students and experts in related fields. The book starts by developing the fundamentals of Markov process theory and then of Gaussian process theory, including sample path properties. It then proceeds to more advanced results, bringing the reader to the heart of contemporary research. It presents the remarkable isomorphism theorems of Dynkin and Eisenbaum and then shows how they can be applied to obtain new properties of Markov processes by using well-established techniques in Gaussian process theory. This original, readable book will appeal to both researchers and advanced graduate students.

American journalists in the 1990s confronted disturbing trends—an erosion of trust in the news media, weakening demand for serious news, flagging interest in politics and civic affairs, and a discouraging public climate that seemed to be getting worse. In response, some news professionals sought to breach the growing gap between press and public with an experimental approach—public journalism. This book is an account of the movement for public journalism, or civic journalism, told by Jay Rosen, one of its leading developers and defenders. Rosen recalls the events that led to the movement’s founding and gives a range of examples of how public journalism is practiced in American newsrooms. He traces the intellectual roots of the movement and shows how journalism can be made vital again by rethinking exactly what journalists are for.Those who have supported the cause of public journalism have focused on first principles: democracy as something we do, citizens as the ones who do it, politics as public problem-solving, and deliberation as a means to that end. Rosen tells what happened as the movement gained momentum in newsrooms around the country and in the professional culture of the press. He reviews the flood of criticism and commentary aimed at public journalism and responds to those who express alarm at the experiment. Examining the mark that the movement has made on the field, Rosen upholds public journalism not only as a way for journalists to find a renewed sense of civic purpose for their craft, but also as a way to improve civic life and strengthen democracy.
