Arising from the legacies of the twentieth century - unprecedented worldwide migration, unrelenting global conflict and warring, unchecked materialist consumption, and unconscionable environmental degradation - are important questions about the toll of loss such changes exact, individually and collectively. As large-scale and ubiquitous as these changes are, their deep specificity re-inscribes the importance of place as a critical construct. Attending to such specificity emphasizes the interconnections between contexts and broader movements and remains a prudent route to articulating critical interconnections among places and peoples in complex times. This book of essays turns to such specificity as a means to examine the inflections of migration on identity- displacement, disorientation, loss, and difference- as sites of both regression and possibility. Fusing autobiography and cultural analysis, it provides a framework for a critical education attuned to such concerns.

This new collection highlights the experiences of an international group of educators as they explore the art of teaching, the philosophy of learning, and the tensions of working across socially constructed borders.

Current research by the US Air Force and Navy is concentrating on obtaining detonations in a pulse detonation engine (PDE) with low vapor pressure, kerosene based jet fuels. These fuels have a low vapor pressure and the performance of a liquid hydrocarbon fueled PDE is significantly hindered by the presence of fuel droplets. A high pressure, fuel flash vaporization system (FVS) has been designed and built to reduce and eliminate the time required to evaporate the fuel droplets. Four fuels are tested: n-heptane, isooctane, aviation gasoline, and JP-8. The fuels vary in volatility and octane number and present a clear picture on the benefits of flash vaporization. Results show the FVS quickly provided a detonable mixture for all of the fuels tested without coking or clogging the fuel lines. Combustion results validated the model used to predict the fuel and air temperatures required to achieve gaseous mixtures with each fuel. The most significant achievement of the research was the detonation of flash vaporized JP-8 and air. The results show that the flash vaporized JP-8 used 20 percent less fuel to ignite the fuel air mixture twice as fast (8 ms from 16 ms) when compared to the unheated JP-8 combustion data.
