Observing Acceleration

This book summarizes five years of learning from data collected as part of the Global Accelerator Learning Initiative. The authors present data describing impact-oriented ventures and accelerators that operate in both high-income countries and in emerging markets. Blending survey data with insights from sector experts, their various analyses shed light on the basic structure of accelerators, showing where they are having their most promising results. Unlike previous studies, this book does not focus on a few high-profile accelerators (like TechStars and Y Combinator) and startups (like AirBnB and Uber). Instead, it compares a range of accelerator programs that target specific impact areas, challenging regions, and marginalized entrepreneurs. Therefore, it serves as a valuable tool for scholars, policymakers, and practitioners interested in the effectiveness of accelerator programs as tools that unleash the economic potential currently trapped in entrepreneurial dead spaces.

This is a collection of review articles and more specialized papers on the main issues of early universe physics. Both theoretical and experimental fields of research are dealt with.

The conversion of energy generated in the Sun's interior creates its hot corona and a wealth of dynamical phenomena such as flares and mass ejections. Based on recent significant progress in understanding magnetic reconnection and a wealth of new observations of energetic particle signatures from the sun, the present volume reviews the current theoretical and experimental status in the field. Paying attention to both the details and the broader picture, this book addresses both the experienced researcher as well as non-specialist researchers from related areas and postgraduate students.

How did electrons in the high atmosphere and space around the Earth come to acquire their speeds and energies? This intriguing question lies at the heart of understanding how high-energy electrons create the spectacular displays of the ^IAurora Borealis and ^IAurora Australis. Electron Acceleration in the Aurora and Beyond explores the mysteries of these phenomena and others involving the acceleration of electrons in the magnetosphere, in the solar wind, at the Sun and in the Cosmos. This book presents a new approach to understanding this fascinating subject by treating the acceleration medium as a plasma. Using this new insight we can see that electron acceleration may well be caused by waves rather than steady potential differences. This unique approach is clearly explained in a lively and engaging style. Quantitative formulae, experiments, practical demonstrations and computer programs enable us to investigate for ourselves how the model works. The theory is further illustrated by comparing acceleration in space with particle accelerators in the nuclear physics laboratory (and even on the sports field!) Questions and exercises with answers are supplied to stimulate further thinking. ^IElectron Acceleration in the Aurora and Beyond is a thought-provoking book for graduate and post-doctoral space scientists.

11 Secrets to Selling Your Business explains in straightforward language and helpful examples how to succeed in profitably valuing and selling your business by avoiding the many mistakes that plague business sellers. Costly mistakes often rob sellers of thousands or, worse yet, hundreds of thousands of dollars of profits when selling or merging their business. Mistakes like breaching confidentiality without agreements in place which allows a competitor to steal valuable customer lists or valuable leases on key locations. Mistakes such as negotiating a great deal without securing buyer financing causing the transaction to crash the day before settlement. Finally, a very misunderstood area, failing to negotiate earn-outs and other price kickers that could add 15% or more to your bottom line with no additional risk. You will see how to create the most valuable business possible at the time you intend to sell. You will be shown all the steps in the business sale process allowing you to structure and negotiate a transaction that will solve your concerns and produce the highest profit when selling your business.

As enjoyable as it is important, this classic encompasses 30 years of highly original experiments and theories. Its lively, readable expositions discuss dynamics, elasticity, sound, strength of materials, more. 126 diagrams.
