This book details the heraldry of the Stealth Fighter beginning 10 years prior to its history-making flights over Baghdad during Operations Desert Shield and Desert Storm. It includes actual photos of many rare F-117A patches produced only for those intimately involved in the F-117A Program. Information dealing with the development of these patches and explaining their symbology are provided. It's also about the people and comaraderie involved. As a bonus, this book contains history and lineage of patches produced during the Lockheed Product Excellence Program's existence for the Engineering and Manufacturing organizations concealed deep within the walls of the highly secretive Skunk Works.

By assuming it is possible to understand regression analysis without fully comprehending all its underlying proofs and theories, this introduction to the widely used statistical technique is accessible to readers who may have only a rudimentary knowledge of mathematics. Chapters discuss:

-descriptive statistics using vector notation and the components of a simple regression model;
-the logic of sampling distributions and simple hypothesis testing;
-the basic operations of matrix algebra and the properties of the multiple regression model; -testing compound hypotheses and the application of the regression model to the analyses of variance and covariance, and
-structural equation models and influence statistics.

Pushed by the Covid-19 crisis, the UK government has borrowed massively to save jobs, businesses and the economy from collapse, making a mockery of the austerity policies that it had championed for a decade. As a result, the role of the state is now in sharp focus. The contributors to this volume assess what that role should be and how it should be harnessed for the good of the British people in all four of its nations. Together they present policy proposals capable of generating a new social settlement and a long-term, equitable economic recovery post-pandemic. It offers both a vision of a future Britain and a roadmap to getting there.

The statues of Savannah's Monument Square are silent. The status of the solemn girl in Bonaventure Cemetery -- made famous in John Berendt's now legendary book, "Midnight in the Garden of Good and Evil" -- cannot speak. Only Savannah's literary monuments can give voice to the rich and diverse history of one of America's greatest and most visited cities. Many have written about Savannah, but few have captured the true spirit of Southern grace most often associated with her history, as well as the mysteries and humor that await behind the walled gardens and gated homes. Whether born there or simply passing through, writers have been inspired by Savannah for centuries, and, in "Literary Savannah, " her stories are finally told.

This study presents the findings of a major investigation of second language proficiency in various groups of school-aged learners, and invites a frank appraisal of the research from an outside panel of experts. The theoretical and practical implications of the study are the subject of a lively debate focused on three main research issues: the nature of second language proficiency, the impact of classroom treatment on second language learning, and the role of social and individual factors in bilingual development. This original collection of articles will be of interest to all those concerned with policy and practice in second language education.

This book provides a practical guide to molecular dynamics and Monte Carlo simulation techniques used in the modelling of simple and complex liquids. Computer simulation is an essential tool in studying the chemistry and physics of condensed matter, complementing and reinforcing both experiment and theory. Simulations provide detailed information about structure and dynamics, essential to understand the many fluid systems that play a key role in our daily lives: polymers, gels, colloidal suspensions, liquid crystals, biological membranes, and glasses. The second edition of this pioneering book aims to explain how simulation programs work, how to use them, and how to interpret the results, with examples of the latest research in this rapidly evolving field. Accompanying programs in Fortran and Python provide practical, hands-on, illustrations of the ideas in the text.
