During the last 20 years, ``localization'' has been one of the dominant themes in the area of equivariant differential geometry. Typical results are the Duistermaat-Heckman theory, the Berline-Vergne-Atiyah-Bott localization theorem in equivariant de Rham theory, and the ``quantization commutes with reduction'' theorem and its various corollaries. To formulate the idea that these theorems are all consequences of a single result involving equivariant cobordisms, the authors have developed a cobordism theory that allows the objects to be non-compact manifolds. A key ingredient in this non-compact cobordism is an equivariant-geometrical object which they call an ``abstract moment map''. This is a natural and important generalization of the notion of a moment map occurring in the theory of Hamiltonian dynamics. The book contains a number of appendices that include introductions to proper group-actions on manifolds, equivariant cohomology, Spin${^\mathrm{c}}$-structures, and stable complex structures. It is geared toward graduate students and research mathematicians interested in differential geometry. It is also suitable for topologists, Lie theorists, combinatorists, and theoretical physicists. Prerequisite is some expertise in calculus on manifolds and basic graduate-level differential geometry.

"Mapmaker expertly brings the paranoid thriller into the age of surveillance, and the result is both moving and chilling." —D.B. Weiss, co-creator, writer, and producer of Game of Thrones When Tanya Barrett takes an internship at MapOut, she expects emotional landmines. Her father cofounded the digital mapping company, and he died for it—on a cartographic expedition. Her father’s business partner welcomes her with open arms, as does his son, Connor, an old childhood friend. To Tanya’s surprise being with Connor turns out to be the only thing that makes her feel happy. But when the two of them accidentally stumble across a deadly secret, Connor disappears. Alone again—and on the run—Tanya must rely on her wits and innate gifts to find out what happened to him and to evade MapOut. In the world their fathers helped create, no one stays lost for long.

The Laurence and Lynne Brown Democracy Medal is an initiative of the McCourtney Institute for Democracy at Pennsylvania State University. It annually recognizes outstanding individuals, groups, and organizations that produce exceptional innovations to further democracy in the United States or around the world. Micah Altman and Michael P. McDonald unveil the Public Mapping Project, which developed DistrictBuilder, an open-source software redistricting application designed to give the public transparent, accessible, and easy-to-use online mapping tools. As they show, the goal is for all citizens to have access to the same information that legislators use when drawing congressional maps—and use that data to create maps of their own. Thanks to generous funding from The Pennsylvania State University, the ebook editions of this book are available as Open Access volumes from Cornell Open (cornellpress.cornell.edu/cornell-open) and other repositories.

Conversations About Group Concept Mapping: Applications, Examples, and Enhancements takes a concise, practice-based approach to group concept mapping. After defining the method, demonstrating how to design a project, and providing guidelines to analyze the results, this book then dives into real research exemplars. Conversations with the researchers are based on in depth interviews that connected method, practice and results. The conversations are from a wide variety of research settings, that include mapping the needs of at-risk African American youth, creating dialogue within a local business community, considering learning needs in the 21st century, and identifying the best ways to support teens receiving Supplemental Social Security Income. The authors reflect on the commonalities between the cases and draw out insights into the overall group concept mapping method from each case.

The Sit Room brings you inside the secretive Situation Room of the White House, the most important deliberative room in the world, during the early 1990s when the author was one of the policymakers who framed the Clinton Administration's policy towards the bloody Balkans War. Drawing upon newly declassified documents and his own notes, David Scheffer, who later became America's first Ambassador-at-Large for War Crimes Issues, weaves the true story of how policy options were debated in the Sit Room among the highest national security officials. The road to a final peace deal in late 1995 came at the high price of the murderous siege of Sarajevo and ethnic cleansing of mostly Bosnian Muslims from their homes and towns, including the genocide of Srebrenica's men and teenage boys. The Sit Room reveals the behind-the-scenes story about how American policy evolved--often futilely--to try to stop an intractable war and its shocking atrocities. Main actors in the Sit Room include: the assertive Ambassador to the United Nations, Madeleine Albright; the State Department's ace negotiator, Richard Holbrooke; the cerebral National Security Adviser, Tony Lake; the immigrant Chairman of the Joint Chiefs of Staff, John Shalikashvili; the bulldog Deputy National Security Adviser, Sandy Berger; and White House moralist, David Gergen. For almost three years, the Sit Room was littered with shattered proposals to end the war-until armed force backed up diplomacy to compel a fragile peace deal. The Sit Room reveals authentic policy-making at the highest levels, with a unique journey into the arena of war and peace where spirited debate guided America's foreign policy.

Health care systems are complex and, as a result, it is often unclear what the effects of changes in policy or service provision might be. At the same time, resources for health care tend to be in short supply, which means that public health practitioners have to make difficult decisions. This book describes the quantitative and qualitative methods that can help decision-makers to structure and clarify difficult problems and to explore the implications of pursuing different options. The accompanying CD ROM provides the opportunity to try out some of the proposed solutions. The book examines: Models and decision-making in health care Methods for clarifying complex decisions Models for service planning and resource allocation Modelling for evaluating changes in systems Series Editors: Rosalind Plowman and Nicki Thorogood.
