Aimed toward graduate students and research mathematicians, with minimal prerequisites this book provides a fresh take on Alexandrov geometry and explains the importance of CAT(0) geometry in geometric group theory. Beginning with an overview of fundamentals, definitions, and conventions, this book quickly moves forward to discuss the Reshetnyak gluing theorem and applies it to the billiards problems. The Hadamard–Cartan globalization theorem is explored and applied to construct exotic aspherical manifolds.

This book expands anthropological studies of business enterprise to include comparative and interdisciplinary perspectives. A number of books on business anthropology have been published, but most of them are written by anthropologists alone. By contrast, this book engages interdisciplinary studies, e.g., not only by anthropologists but also management scholars and other social scientists. It is the second volume of studies forwarding anthropological approaches to business administration, Keiei Jinruigaku.

Il Maggiore, un veterano della Seconda guerra mondiale, esala in ospedale il suo ultimo respiro. A vegliarlo, sua moglie e il cane Tassen. La macchia sul naso gli ha impedito di sfilare nelle mostre canine, ma gli ha fatto scoprire in casa Thorkildsen l'affetto di una vera famiglia. Purtroppo, ora, le cose non vanno granché bene: Tassen e la signora Thorkildsen devono ricominciare una nuova vita, loro due soli, e non è semplice, per Tassen, che è un cane da un solo padrone, e per la donna, sempre più evanescente e smarrita. Beve troppa «acqua del drago» e non uscirebbe più di casa, se non ci fosse lui. Ma Tassen non sarebbe un cane speciale se non sapesse cosa fare per risolvere la situazione: a suo modo, naturalmente. La storia della corsa al Polo Sud, la gara che vide protagonisti, nel 1911, l'esploratore norvegese Roald Amundsen e il suo rivale, il capitano inglese Robert Scott, diventa la loro passione..

"Euler as Physicist" analyzes the exceptional role of Leonhard Euler (1707 - 1783) in the history of science and emphasizes especially his fundamental contributions to physics. Although Euler is famous as the leading mathematician of the 18th century, his contributions to physics are as important for their innovative methods and solutions. Several books are devoted to Euler as mathematician, but none to Euler as physicist, like in this book.

Healthcare service systems are of profound importance in promoting the public health and wellness of people. This book introduces a data-driven complex systems modeling approach (D2CSM) to systematically understand and improve the essence of healthcare service systems. In particular, this data-driven approach provides new perspectives on health service performance by unveiling the causes for service disparity, such as spatio-temporal variations in wait times across different hospitals.
