Which cultural values, beliefs, and attitudes best promote democracy, social justice, and prosperity? How can we use the forces that shape cultural change, such as religion, education, and political leadership, to promote these values in the Third World--and for underachieving minorities in the First World? In this book, Lawrence E. Harrison offers intriguing answers to these questions, in a valuable follow-up to his acclaimed Culture Matters. Drawing on a three-year research project that explored the cultural values of dozens of nations--from Botswana, Sweden, and India to China, Egypt, and Chile--Harrison offers a provocative look at values around the globe, revealing how each nation's cul...
The study of Euclidean distance matrices (EDMs) fundamentally asks what can be known geometrically given onlydistance information between points in Euclidean space. Each point may represent simply locationor, abstractly, any entity expressible as a vector in finite-dimensional Euclidean space.The answer to the question posed is that very much can be known about the points;the mathematics of this combined study of geometry and optimization is rich and deep.Throughout we cite beacons of historical accomplishment.The application of EDMs has already proven invaluable in discerning biological molecular conformation.The emerging practice of localization in wireless sensor networks, the global posi...
The late Albert Elsen was the first American scholar to study seriously the work of the French sculptor Auguste Rodin, and the person most responsible for a revival of interest in the artist as a modern innovator--after years during which the sculpture had been dismissed as so much Victorian bathos. After a fortuitous meeting with the financier, philanthropist, and art collector B. Gerald Cantor, Elsen helped Cantor to build up a major collection of Rodin's work. A large part of this collection, consisting of more than 200 pieces, was donated to the Stanford Museum by Mr. Cantor, who died recently. In size it is surpassed only the by the Musée Rodin in Paris and rivaled only by the collecti...
This volume presents refereed papers presented at the workshop Semidefinite Programming and Interior-Point Approaches for Combinatorial Problems: held at The Fields Institute in May 1996. Semidefinite programming (SDP) is a generalization of linear programming (LP) in that the non-negativity constraints on the variables is replaced by a positive semidefinite constraint on matrix variables. Many of the elegant theoretical properties and powerful solution techniques follow through from LP to SDP. In particular, the primal-dual interior-point methods, which are currently so successful for LP, can be used to efficiently solve SDP problems. In addition to the theoretical and algorithmic questions, SDP has found many important applications in combinatorial optimization, control theory and other areas of mathematical programming. The papers in this volume cover a wide spectrum of recent developments in SDP. The volume would be suitable as a textbook for advanced courses in optimization. It is intended for graduate students and researchers in mathematics, computer science, engineering and operations.
This book constitutes the refereed proceedings of the 11th International Conference on Integer Programming and Combinatorial Optimization, IPCO 2005, held in Berlin, Germany in June 2005. The 34 revised full papers presented were carefully reviewed and selected from 119 submissions. Among the topics addressed are mixed-integer programming, graph theory, graph algorithms, approximation, linear programming, approximability, packing, scheduling, computational geometry, randomization, network algorithms, sequencing, TSP, and travelling salesman problem.
This title is written in honor of Manfred Padberg, who has made fundamental contributions to both the theoretical and computational sides of integer programming and combinatorial optimization. This outstanding collection presents recent results in these areas that are closely connected to Padberg's research. His deep commitment to the geometrical approach to combinatorial optimization can be felt throughout this volume; his search for increasingly better and computationally efficient cutting planes gave rise to its title. The peer-reviewed papers contained here are based on invited lectures given at a workshop held in October 2001 to celebrate Padberg's 60th birthday. Grouped by topic (packing, stable sets, and perfect graphs; polyhedral combinatorics; general polytopes; semidefinite programming; computation), many of the papers set out to solve challenges set forth in Padberg's work. The book also shows how Padberg's ideas on cutting planes have influenced modern commercial optimization software.

This book constitutes the refereed proceedings of the 7th International Conference on Integer Programming and Combinatorial Optimization, IPCO'99, held in Graz, Austria, in June 1999. The 33 revised full papers presented were carefully reviewed and selected from a total of 99 submissions. Among the topics addressed are theoretical, computational, and application-oriented aspects of approximation algorithms, branch and bound algorithms, computational biology, computational complexity, computational geometry, cutting plane algorithms, diaphantine equations, geometry of numbers, graph and network algorithms, online algorithms, polyhedral combinatorics, scheduling, and semidefinite programs.
This article investigates structural, geometrical, and topological characteri-zations and properties of weakly modular graphs and of cell complexes derived from them. The unifying themes of our investigation are various “nonpositive cur-vature” and “local-to-global” properties and characterizations of weakly modular graphs and their subclasses. Weakly modular graphs have been introduced as a far-reaching common generalization of median graphs (and more generally, of mod-ular and orientable modular graphs), Helly graphs, bridged graphs, and dual polar graphs occurring under different disguises (1–skeletons, collinearity graphs, covering graphs, domains, etc.) in several seemingly-u...
The Third Republic, known as the ‘belle époque’, was a period of lively, articulate and surprisingly radical feminist activity in France, borne out of the contradiction between the Republican ideals of liberty, equality and fraternity and the reality of intense and systematic gender discrimination. Yet, it also was a period of intense and varied artistic production, with women disproving the critical nearconsensus that art was a masculine activity by writing, painting, performing, sculpting, and even displaying an interest in the new "seventh art" of cinema. This book explores all these facets of the period, weaving them into a complex, multi-stranded argument about the importance of this rich period of French women’s history.
