  “Football’s massive popularity is undeniable, as are the many reasons players and fans are drawn to the game. But what is also undeniable is the game’s brutality and the troubling aspects of football culture at all levels. To whatever extent the reader shares Irv Muchnick’s perspective and conclusions, the evidence and arguments he presents deserve thoughtful attention.” — Bob Costas, Emmy Award–winning sportscaster 
  		 
  “Muchnick’s jeremiad digs deeper than ever into the greed and hypocrisy of high school and college football, and the trail of broken bodies left in their wake. His information on the perils of conditioning is essential reading and might save your kid’s life.” — Robert Lipsyte, author of The Contender and SportsWorld
  		 
  Football’s concussion crisis is well known, with our Hall of Fame heroes behaving erratically and dying young. But did you know that kid players across the continent die every year before a single ball is snapped — just from extreme conditioning drills directed by all-powerful coaches? And then, when the unimaginable happens, the football world simply buries the evidence, pays off victims’ families, and moves on …
  		 
  Without Helmets or Shoulder Pads presents the shocking stories of young men struck down by exertional heatstroke and other, often unacknowledged, causes. Taking the conversation about football and public health to a new level with investigations of the sport’s underreported worst tragedies and cover-ups it makes the case that no matter how much we enjoy America’s most popular sport at elite levels it belongs out of our public schools and off our public fields.

  England & Wales Island Bagging by Lisa Drewe is a stunning and informative guide to the islands of England, Wales, the Channel Islands and the Isle of Man. It is ideal for swimmers, kayakers, adventure travellers, wildlife spotters and ice cream connoisseurs.
  Go on an inspirational and fascinating coastline journey – familiar islands are visited, such as Lundy and the Isle of Wight; others are less well known, such as Gewni in Pembrokeshire and Coquet Island in Northumberland. Almost 300 islands are included, from larger, populated islands to remote, uninhabited islets – some can be reached by foot at low tide, others have ferry services, and some you will need your own transport, or be content to view them from the mainland.
  Once you've found your island this book introduces you to the best sites on the island to appreciate: hidden beaches and coves, the tastiest local food and the wildlife that can be seen in the locality. Watch the Cemlyn Bay terns on Anglesey, go paddleboarding around Mersea Island in Essex, walk in the footsteps of pilgrims on Lindisfarne in Northumberland, or enjoy ice cream from one of the smallest dairy herds in the country on St Agnes in the Isles of Scilly … it's all there to be enjoyed in England & Wales Island Bagging.

  What can fossilized teeth tell us about our ancient life expectancy? What can big data on fossils reveal about farming's problematic role in human evolution? How can simple geometric comparisons of skull and pelvic fossils suggest an origin to our social nature?In Close Encounters with Humankind, paleoanthropologist Sang-Hee Lee explores some of our biggest evolutionary questions from unexpected new angles. Through a series of entertaining, bite-sized chapters, we gain new perspectives into our first hominin ancestors, our first steps on two feet, our first forays into toolmaking and hunting, and of course our continuing evolution.

  Fast Fourier Transforms

  C. Sidney Burrus

  This book focuses on the discrete Fourier transform (DFT), discrete convolution, and, particularly, the fast algorithms to calculate them. These topics have been at the center of digital signal processing since its beginning, and new results in hardware, theory and applications continue to keep them important and exciting.
  
   
  As far as we can tell, Gauss was the first to propose the techniques that we now call the fast Fourier transform (FFT) for calculating the coefficients in a trigonometric expansion of an asteroid's orbit in 1805. However, it was the seminal paper by Cooley and Tukey in 1965 that caught the attention of the science and engineering community and, in a way, founded the discipline of digital signal processing (DSP).
  
   
  The impact of the Cooley-Tukey FFT was enormous. Problems could be solved quickly that were not even considered a few years earlier. A flurry of research expanded the theory and developed excellent practical programs as well as opening new applications. In 1976, Winograd published a short paper that set a second flurry of research in motion. This was another type of algorithm that expanded the data lengths that could be transformed efficiently and reduced the number of multiplications required. The ground work for this algorithm had be set earlier by Good and by Rader. In 1997 Frigo and Johnson developed a program they called the FFTW (fastest Fourier transform in the west) which is a composite of many of ideas in other algorithms as well as new results to give a robust, very fast system for general data lengths on a variety of computer and DSP architectures. This work won the 1999 Wilkinson Prize for Numerical Software.
  
   
  It is hard to overemphasis the importance of the DFT, convolution, and fast algorithms. With a history that goes back to Gauss and a compilation of references on these topics that in 1995 resulted in over 2400 entries, the FFT may be the most important numerical algorithm in science, engineering, and applied mathematics. New theoretical results still are appearing, advances in computers and hardware continually restate the basic questions, and new applications open new areas for research. It is hoped that this book will provide the background, references, programs and incentive to encourage further research and results in this area as well as provide tools for practical applications.
  
   
  Studying the FFT is not only valuable in understanding a powerful tool, it is also a prototype or example of how algorithms can be made efficient and how a theory can be developed to define optimality. The history of this development also gives insight into the process of research where timing and serendipity play interesting roles.
  
   
  Several chapters or sections are written by authors who have extensive experience and depth working on the particular topics. Ivan Selesnick had written several papers on the design of short FFTs to be used in the prime factor algorithm (PFA) FFT and on automatic design of these short FFTs. Markus Püschel has developed a theoretical framework for “Algebraic Signal Processing" which allows a structured generation of FFT programs and a system called “Spiral" for automatically generating algorithms specifically for an architicture. Steven Johnson along with his colleague Matteo Frigo created, developed, and now maintains the powerful FFTW system: the Fastest Fourier Transform in the West. I sincerely thank these authors for their significant contributions.

  The Development of Unmanned Aerial Conflict will examine the development and use of aerial drones, a topical subject that has not been written on to date.An unmanned aerial vehicle, commonly known as a drone, is an aircraft without a human pilot on board. Its flight is either controlled autonomously by computers in the vehicle, or under the remote control of a navigator or pilot on the ground or in another vehicle.Blending history with current and recent operations, Dr Sloggett will set out to put the record straight. In some quarters of the press drones get a bad press and there has been much controversy over their deployment, some of which is not deserved.The book reveals the history of unmanned aircraft, their recent development and why they have emerged onto the scene. Why did the US, for example, really invest highly in drone technology? When did all that start? What barriers had to be overcome? What was there before drones arrived?The book also analyses their operations in Iraq in Gulf War Two and more recently Afghanistan. What roles did drones play? Where they successful? What new developments emerged during operations? Did they save lives? Further to this is a detailed look at case studies where they have been used trying to remove some of the incorrect reporting – putting the record straight based on evidence. How many have been shot down and where?The book then looks at strategic uses of drones at present: Iran is being monitored; they are already in action over parts of Africa; what are other countries doing – China, Iran? Turkey?The RAF's use of drones, their deployment and operations is considered along with important questions such as where this goes for the future. What are the issues? Will all air forces be drone based in the future? What other applications may arise in the civilian market?
