This commemorative book contains the 28 major articles that appeared in the 2008 Twentieth Anniversary Issue of the journal Discrete & Computational Geometry, and presents a comprehensive picture of the current state of the field. The articles in this volume, a number of which solve long-outstanding problems in the field, were chosen by the editors of DCG for the importance of their results, for the breadth of their scope, and to show the intimate connections that have arisen between discrete and computational geometry and other areas of both computer science and mathematics. Apart from the articles, the editors present an expanded preface, along with a set of photographs of groups and individuals who have played a major role in the history of the field during the past twenty years.

Gender and women’s studies have formed part of the academic landscape for many years, but while the field is now established enough to have developed in depth and perspectives, there remain many areas of significance yet to be explored–most significantly, much of the work carried out has remained rooted in the Anglo-American context. Those working outside this context are increasingly aware of the need to understand women in different cultural contexts in order to determine whether, to what extent and how representations of women and cultural contexts are interactive and dynamic concepts. The current volume contributes to the growing interest in the field of women and culture in the Hispanic and Lusophone worlds and shows how women writers, researchers, teachers and students have always made waves to counteract the complacency, prejudice and tradition that threatens to ignore or subsume them. The volume draws on literary study–the starting point for much of the early work on gender in Spain, the Lusophone world and Latin America–but also goes beyond it, to discuss women’s interaction not only with literature but also with art, and language itself, in the Hispanic and Lusophone contexts. It acts as a showcase for contemporary scholarship undertaken in Hispanic and Lusophone gender studies, developing earlier insights and forging new ones, to refine the debate continuing in the subject. The contributors include both established scholars with a proven track record and promising newcomers to the field. The volume arises from the individual research projects and sustained discussions of Women in Spanish, Portuguese and Latin American Studies (WiSPs), an organisation that exists to promote scholarship by and about women in the field of Iberian, Lusophone and Latin American Studies. This volume celebrates the first seven years of WiSPs's life and presents some of the research presented under its auspices at annual conferences and study days.

The journal Boundary-Layer Meteorology was started in 1970 and has become the premier vehicle for the publication of research papers in its field. Dr R.E. Munn served as Editor-in-Chief until recently. The special 25th Anniversary volume, on which this book is based, was compiled from review and other articles solicited and selected as a `Festschrift' to honour Ted Munn's achievement as editor of the journal over that time. Articles by leading contributors to the field include reviews of field studies (Askervein, HEXOS, Cabauw) and their impacts; numerical modelling (large-eddy simulation of the surface layer, frontal structures); analyses and critical discussions (of the von Karman constant, bulk aerodynamic formulations, air-sea interaction, vegetation canopies); and reviews or previews of progress in our understanding of the atmospheric boundary layer, turbulence simulation, Lagrangian descriptions of turbulent diffusion and remote sensing of the boundary layer. The collection provides an excellent perspective on the state of the subject and where it is headed. It should provide fascinating and stimulating reading for researchers and students of boundary-layer meteorology and related areas.

This book is a volume in the Penn Press Anniversary Collection. To mark its 125th anniversary in 2015, the University of Pennsylvania Press rereleased more than 1,100 titles from Penn Press's distinguished backlist from 1899-1999 that had fallen out of print. Spanning an entire century, the Anniversary Collection offers peer-reviewed scholarship in a wide range of subject areas.
