Clearing houses, or CCPs, were among the very few organisations to emerge from the global financial crisis with their standing enhanced. In the chaotic aftermath of the bankruptcy of Lehman Brothers, they successfully completed trades worth trillions of dollars in a multitude of financial instruments across listed and over-the-counter markets, and so helped avert financial Armageddon. That success transformed the business of clearing. Governments and regulators around the world gave CCPs and the clearing services they provide a front-line role in protecting the global economy from future excesses of finance. CCPs, which mitigate risk in financial markets, responded by greatly expanding their activities, notably in markets for over-the-counter derivatives, and often in fierce competition with one another. In The Risk Controllers, journalist and author Peter Norman describes how CCPs operate, how they handled the Lehman default, and the challenges they now face. Because central counterparty clearing is a complex business with a long history that continues to influence decisions and structures even in today’s fast changing world, The Risk Controllers explores the development of CCPs and clearing from the earliest times to the present. It draws on the experiences of the people who helped to shape the business of clearing today. It sets the development of CCPs and clearing in the broader context of changes in society, politics and regulation. The book examines turning points, such as the 1987 stock market crash, that set clearing on a new path and the impact of long running trends, including the exponential growth of computer power and the ebb and flow of globalisation. Written in non-technical language, The Risk Controllers provides a unique and accessible guide to CCPs and clearing. It is essential reading for clearing professionals, legislators and regulators whose job it is to take this vitally important business into the future. “The recent crisis has, thankfully, renewed interest in the importance of central counterparties: how they can help preserve stability or, as Hong Kong showed in 1987, undermine stability if they are not super sound. Peter Norman’s book places the role of clearing houses in a historical context, and explains why the financial system’s plumbing matters so much. It should be read by anyone interested in building safer capital markets.” Paul Tucker, Deputy Governor Financial Stability, Bank of England

This book covers the principles of modeling and simulation of nonlinear distortion in wireless communication systems with MATLAB simulations and techniques In this book, the author describes the principles of modeling and simulation of nonlinear distortion in single and multichannel wireless communication systems using both deterministic and stochastic signals. Models and simulation methods of nonlinear amplifiers explain in detail how to analyze and evaluate the performance of data communication links under nonlinear amplification. The book addresses the analysis of nonlinear systems with stochastic inputs and establishes the performance metrics of communication systems with regard to nonlinearity. In addition, the author also discusses the problem of how to embed models of distortion in system-level simulators such as MATLAB and MATLAB Simulink and provides practical techniques that professionals can use on their own projects. Finally, the book explores simulation and programming issues and provides a comprehensive reference of simulation tools for nonlinearity in wireless communication systems. Key Features: Covers the theory, models and simulation tools needed for understanding nonlinearity and nonlinear distortion in wireless systems Presents simulation and modeling techniques for nonlinear distortion in wireless channels using MATLAB Uses random process theory to develop simulation tools for predicting nonlinear system performance with real-world wireless communication signals Focuses on simulation examples of real-world communication systems under nonlinearity Includes an accompanying website containing MATLAB code This book will be an invaluable reference for researchers, RF engineers, and communication system engineers working in the field. Graduate students and professors undertaking related courses will also find the book of interest.

A game-changing approach to management Too often discussions of management practice focus exclusively on managing people and organizational issues. Rarely, however, do they incorporate a discussion about technology or address all three dimensions in a balanced way. When they do, the result is game changing. In our hypercompetitive environment, those managers who are outstanding at being plugged into their people, technology, and organizational processes simultaneously excel at coming up with effective business solutions. The Plugged-In Manager makes the case that being plugged-in—the ability to see choices across each of an organization's dimensions of people, technology, and organizational processes and then to mix them together into new and powerful organizational strategies, structures, and practices—may be the most important capability a manager can develop to succeed in the 21st century. Step by step Griffith shows you how to acquire this ability. Shows what it takes for business managers to succeed as technology and organizations become more and more complex Profiles exceptional leaders and organizations who are plugged-in, such as Tony Hsieh, CEO of Zappos.com Offers a fresh look at management issues Filled with compelling case studies and drawing on first-hand interviews, The Plugged-In Manager highlights this often neglected managerial capability and the costs of only focusing on one dimension rather than all three.

Real life insights on what it takes to make it in a relationship with an entrepreneur Entrepreneurs are always on the go, looking for the next «startup» challenge. And while they lead very intensely rewarding lives, time is always short and relationships are often long-distant and stressed because of extended periods apart. Coping with these, and other obstacles, are critical if an entrepreneur and their partner intend on staying together—and staying happy. In Startup Life, Brad Feld—a Boulder, Colorado-based entrepreneur turned-venture capitalist—shares his own personal experiences with his wife Amy, offering a series of rich insights into successfully leading a balanced life as a human being who wants to play as hard as he works and who wants to be as fulfilled in life and in work. With this book, Feld distills his twenty years of experience in this field to addresses how the village of startup people can put aside their workaholic ways and lead rewarding lives in all respects. Includes real-life examples of entrepreneurial couples who have had successful relationships and what works for them Provides practical advice for adapting to change and overcoming the inevitable ups and downs associated with the entrepreneurial lifestyle Written by Brad Feld, a thought-leader in this field who has been an early-stage investor and successful entrepreneur for more than twenty years While there's no «secret formula» to relationship success in the world of the entrepreneur, there are ways to making navigation of this territory easier. Startup Life is a well-rounded guide that has the insights and advice you need to succeed in both your personal and business life.
