In her elective home country of Mexico, the artist Olga Costa (1913-1993), a native of Leipzig, has long been established as an important female voice of Mexican Modernism. This volume presents impressively her autonomous artistic work between Mexican and European Modernism, and follows the traces of her life from Germany out into the world and back again. As the daughter of a Jewish-Ukrainian musician, the autodidact Olga Costa emigrated to Mexico in the 1920s, where she explored her new surroundings in her painting. Throughout her life she was not only inspired by people's everyday lives and the intensive colours of the landscape, but also by the dialogue with other artistic positions. It was not least Costa's examination of questions of cultural identity and feminism as well as her broad cultural-political commitment that made her one of the most important women artists in the circle surrounding Frida Kahlo.

The Soviet forces in Europe have dramatically modernized their equipment and are the most heavily armed in the world. The United States tactical air force has responded with increased emphasis on readiness and realistic training. In particular, Red Flag and the aggressor squadrons are two of the most innovative and productive programs that have been developed for the fighter force. This thesis addresses the relevancy of the training by focusing on the Soviet threat and current fighter force training doctrine. A very limited "first battle" scenario in the European theater is presented to analyze the training versus the threat. The general conclusion of this study is that the current combat training of United States tactical fighter forces is excellent. The recent emphasis on readiness has definitely made the training relevant to the threat. There are, however, several areas that require additional emphasis and improvement. This thesis proposes specific recommendations in the areas of air superiority, the fighter/forward air controller/strike control and reconnaissance concept, combat deployments, and night operations.
