This book highlights the reasons for an urgently needed revision of the current global healthcare setup, discusses the needed mindset for a future of health, and provides a comprehensive development toolset for disruption (and for the needed incremental innovations towards disruption).Today’s biomedical and health innovation related research in universities encourages activities that lead to incremental innovations with a relatively low risk of failure. The healthcare industry on the other hand provides tools and devices for established healthcare providers to improve the diagnosis and therapy/ treatment of the patients’ health problems. The patient is not in the center of healthcare provision however, and prevention and prediction are not core goals. The current health setup needs to be challenged and disrupted.Disruptions are coming from technologies or processes that lead to a significant (>10x) reduction in cost or price/ performance and that also come with new business models. The need for change, effects of exponential technologies, and the needed shift to prevention and to homecare for health democratization and patient empowerment will be discussed in detail in the first parts of the book. The subsequent sections address several innovation methods with a focus on a novel meta methodology named Purpose Launchpad Health. This is followed by a comprehensive discussion on health entrepreneurship activities and needs. The final section of the book addresses how to train students to become entrepreneurial health innovators, presenting successful curricula and examples of health incubation and accelerator setups. All of the innovation tools presented and used in this book are summarized in the final chapter to help the reader get started planning an entrepreneurial venture.Written by experts from academia and industry, the book covers important basics and best practices, as well as recent developments. Chapters are concise and enriched with key messages, learning objectives and real innovation examples to bridge theory and practice. This book aims to serve as a teaching base for health innovation design and to prepare for health-related entrepreneurial ventures.Readers with medical, biomedical, biotechnology, and health economics backgrounds - and anyone who wants to become a future oriented health innovator or who believes in disruptive approaches - will find this book a useful resource and teaching tool for developing validated products/ services and processes for the future of health.

This book stands at the intersection of two topics: the decidability and computational complexity of hybrid logics, and the deductive systems designed for them. Hybrid logics are here divided into two groups: standard hybrid logics involving nominals as expressions of a separate sort, and non-standard hybrid logics, which do not involve nominals but whose expressive power matches the expressive power of binder-free standard hybrid logics.The original results of this book are split into two parts. This division reflects the division of the book itself. The first type of results concern model-theoretic and complexity properties of hybrid logics. Since hybrid logics which we call standard are quite well investigated, the efforts focused on hybrid logics referred to as non-standard in this book. Non-standard hybrid logics are understood as modal logics with global counting operators (M(En)) whose expressive power matches the expressive power of binder-free standard hybrid logics. The relevant results comprise: 1. Establishing a sound and complete axiomatization for the modal logic K with global counting operators (MK(En)), which can be easily extended onto other frame classes, 2. Establishing tight complexity bounds, namely NExpTime-completeness for the modal logic with global counting operators defined over the classes of arbitrary, reflexive, symmetric, serial and transitive frames (MK(En)), MT(En)), MD(En)), MB(En)), MK4(En)) with numerical subscripts coded in binary. Establishing the exponential-size model property for this logic defined over the classes of Euclidean and equivalential frames (MK5(En)), MS5(En)).Results of the second type consist of designing concrete deductive (tableau and sequent) systems for standard and non-standard hybrid logics. More precisely, they include: 1. Devising a prefixed and an internalized tableau calculi which are sound, complete and terminating for a rich class of binder-free standard hybrid logics. An interesting feature of indicated calculi is the nonbranching character of the rule (¬D), 2. Devising a prefixed and an internalized tableau calculi which are sound, complete and terminating for non-standard hybrid logics. The internalization technique applied to a tableau calculus for the modal logic with global counting operators is novel in the literature, 3. Devising the first hybrid algorithm involving an inequality solver for modal logics with global counting operators. Transferring the arithmetical part of reasoning to an inequality solver turned out to be sufficient in ensuring termination.The book is directed to philosophers and logicians working with modal and hybrid logics, as well as to computer scientists interested in deductive systems and decision procedures for logics. Extensive fragments of the first part of the book can also serve as an introduction to hybrid logics for wider audience interested in logic.The content of the book is situated in the areas of formal logic and theoretical computer science with some elements of the theory of computational complexity.

Basic Fundamentals in Hearing Science is a practical textbook written primarily for college undergraduates preparing for graduate programs in speech-language pathology or audiology. Using Newtonian physics, the authors present a novel approach to the subject of hearing science enabling students to develop their understanding of the subject while building their knowledge of scientific concepts as they move through the text. Students progress from the basics to more difficult concepts in a graduated process. The text encourages thinking and problem solving rather than learning by rote memorization and clarifies obscure concepts in a writing style that promotes greater understanding and comprehension. Pedagogical elements include key terms listed for each chapter, bulleted chapter summaries, and review questions at the end of each chapter. For undergraduate hearing science students without hard science backgrounds, this text aims to decompress and facilitate the comprehension of difficult and often cumbersome concepts in order to master the basic concepts in hearing science.This textbook is also a useful supplemental or recommended reference for speech and hearing combined courses that require more coverage of hearing science than currently available in speech-oriented textbooks. "'Key features of "Basic Fundamentals in Hearing Science" include:"' * An extensive number of figures and illustrations for improved overall comprehension of the subject matter * Clear descriptions of the many and various forms of sound wave phenomenon, and of auditory anatomy and physiology--from the outer ear to the auditory cortex * An overview of scientific measurement scales and notation including the use of logarithms, exponential and scientific notation, and the metric system * An opening chapter that defines and elucidates the meaning, practice, and philosophy of science--with an emphasis on theory-driven research--including a practical guide for the writing of a scientific manuscript * Chapters devoted to the basic terminology used in hearing science and the application of those basic principles and terms, as well as a chapter that addresses basic nervous system terminology and describes the structure and function of the twelve pairs of cranial nerves * A chapter that deals exclusively with the structure and function of the auditory system ================================================================== "The text is written with meticulous and thorough attention to detail and accuracy.This is especially apparent with regard to the formulas and tables provided for the computations of the Bel, decibel, and RMS amplitude. An additional feature that adds to the attractiveness and flair of the book is the frequent reference to historic discoveries and to those who made them. Concepts presented in the text are beautifully complemented by illustrations, graphs, and equations. This is a book I wish I had had when I was a student, and I believe it will become a first choice textbook among undergraduate and graduate students. It will provide quick answers to questions, both simple and complex, and will provide ever-deepening insights into hearing science when knowledge of details is the goal." -- From the Foreword by James A. Kaltenbach, PhD, Director of Otology Research, The Cleveland Clinic

This revised second edition presents 15 years of data on Virtual Distance metrics and their predictive impact on organizational success factors shedding new light on how to correct for communication challenges that often show up as a foggy set of digital disconnects where the vitality of the virtual workforce often gets lost in transmission. This still-evolving Digital Age conundrum continues to present new complications. The rise of remote work which rests on an increasing reliance on electronic communication and the overall growth of virtual interactions has led to the escalation of a phenomenon called Virtual Distance. Virtual Distance, which influences our behavior through three components Physical Distance, Operational Distance, and Affinity Distance affects not only how we relate to others thousands of miles away but even to co-workers sitting right next to each other! Perhaps even more problematic, Virtual Distance causes measureable malfunctions in teamwork, innovation, leader effectiveness and overall performance. But it doesn’t have to be this way. The Power of Virtual Distance offers specific, proven and predictable solutions that can reverse these trends and turn Virtual Distance into a unification strategy to capture untapped competitive advantage. Surprised? The Power of Virtual Distance, 2nd Edition is a must-read for leadership who want to understand the true and quantifiable costs of the virtual workplace. For the first time ever, readers can take the guesswork out of managing the virtual workforce by applying a mathematical approach derived from the extensive Virtual Distance data set: The Virtual Distance Ratio. The Virtual Distance Ratio can precisely pinpoint the particular impacts of Virtual Distance on the organization’s critical success factors. Beyond business metrics, Virtual Distance solutions also detail ways to restore meaningfulness and well-being into people’s experience of work, enhancing life lived in the Digital Age. The Power of Virtual Distance reveals an updated set of data, including the first award-winning analysis, collected from an extended range of executives to individual contributors, that represent situations and solutions in more than 36 industries in 55 countries across the globe. Readers will get a “first look” at the data and its revelations on how to be less isolated and more integrated. Helping managers globally, this book: Offers new, real-world case studies and a chance for readers to participate in thought experiments to help with personal performance, group synergy and by extension, relationship dynamics of all kinds Demonstrates (with statistically significant trend analyses) that Virtual Distance is growing at exponential rates in every corner of communities worldwide Offers expert advice on how to manage the “unintended human consequences” of today’s digital technologies Companies that successfully harness the power of Virtual Distance demonstrate better performance. The second edition of The Power of Virtual Distance is a valuable, one-of-a-kind resource for everyone – from the C-suite to human resource professionals; from divisional leaders to project managers. Everyone in the organization can benefit by discovering how to improve financials, innovation, trust, employee engagement, satisfaction, organizational citizenship and other key performance indicators. And perhaps best of all, by following the prescriptions on how to reduce Virtual Distance, the entire workforce will have the tools they need to bring about a revival of meaning, purpose and an enlivened sense of “humanhood” back into everyday work and everyday life.

In this colorful and consistently engaging work, law and economics professor Gillian Hadfield picks up where New York Times columnist Thomas Friedman left off in his influential 2005 book, The World is Flat. Friedman was focused on the infrastructure of communications and technology-the new web-based platform that allows business to follow the hunt for lower costs, higher value and greater efficiency around the planet seemingly oblivious to the boundaries of nation states. Hadfield peels back this technological platform to look at the 'structure that lies beneath'--our legal infrastructure, the platform of rules about who can do what, when and how. Often taken for granted, economic growth throughout human history has depended at least as much on the evolution of new systems of rules to support ever-more complex modes of cooperation and trade as it has on technological innovation. When Google rolled out YouTube in over one hundred countries around the globe simultaneously, for example, it faced not only the challenges of technology but also the staggering problem of how to build success in the context of a bewildering and often conflicting patchwork of nation-state-based laws and legal systems affecting every aspect of the business-contract, copyright, encryption, censorship, advertising and more. Google is not alone. A study presented at the World Economic Forum in Davos in 2011 found that for global firms, the number one challenge of the modern economy is increasing complexity, and the number one source of complexity is law. Today, even our startups, the engines of economic growth, are global from Day One. Put simply, the law and legal methods on which we currently rely have failed to evolve along with technology. They are increasingly unable to cope with the speed, complexity, and constant border-crossing of our new globally inter-connected environment. Our current legal systems are still rooted in the politics-based nation state platform on which the industrial revolution was built. Hadfield argues that even though these systems supported fantastic growth over the past two centuries, today they are too slow, costly, cumbersome and localized to support the exponential rise in economic complexity they fostered. While everything else in the economy strives to become cheaper, sleeker and faster, our outdated approach to law hampers the invention of new products, the development of new business models, the structuring of global supply chains, the management of the risks posed by complex technologies, the evolution of financial, ecological, and other systems, as well as the protection of people and businesses as they and their products travel around the globe. They also fail to address looming challenges such as global warming and the reduction of poverty and oppression in the developing countries that are the backyard of global business. The answer to our troubles with law, however, is not the one critics usually reach for--to have less of it. Recognizing that law provides critical infrastructure for the cooperation and collaboration on which economic growth is built is the first step, Hadfield argues, to building a legal environment that does more of what we need it to do and less of what we don't. Through a sweeping review of first the invention and then the evolution of law over thousands of years of human development and the ways in which rule systems have consistently adapted to higher levels of complexity, Hadfield stresses that the state-based legal systems governing us today are not the only way to build the planks of a legal platform. Going back to fundamentals, she shows how historically, law's primary purpose has been to help societies to cope with the essential issues of trust, commitment, risk-allocation, and distribution that we face in coordinating cooperative ventures. While nation-state laws will never disappear, the time has come for us to supplement our legal infrastructure with rules developed on the same global platform as our economy. Hadfield offers a model for a more market- and globally-oriented legal system that fosters greater participation of end-users, market actors, and other non-governmental entities. Combining an impressive grasp of the empirical details of economic globalization with an ambitious re-envisioning of our global legal system, Rules for a Flat World promises to be a crucial and influential intervention into the debates surrounding how best to manage the evolving global economy.

‘Essential reading.’ – ESQUIRE ‘Both absorbing and highly illuminating’ – THE BOOKSELLER ‘No one understands the intricacies of YouTube like Chris Stokel-Walker’ – THE ATLANTIC Two billion people watch YouTube and it reaches deep into everyday lives. Its creators start new trends, popularise new songs and games and make and break new products. Yet while they are famous to billions of mostly young people, they mostly remain a mystery to the general public and mainstream media. What is the secret of their appeal? How do they cope with being in front of the lens – and who is behind their success? More than 100 insiders spoke candidly to teach journalist Chris Stokel-Walker for this first in-depth independent book on YouTube. YouTubers is the only book you need to understand YouTube, its ownership by Google, its deal for stars and its ecosystem of talent managers, advertisers and marketers. It is a richly-layered deep dive into YouTube brimming with lively characters, engaging facts, and influencer case studies. It is an ideal guide for any media studies students, advertisers, brand managers and business people who need to understand YouTube professionally. And for any non-fiction reader interested in a gripping business and technology saga dripping with big money, ruthlessness, determination and ambition. YouTubers starts by charting the platform's launch in a boring 19-second video of the elephant enclosure at San Diego Zoo – which has now had 242 million views. YouTubers then moves onto the first oddball videos before the site found success by showing comedy clips from the TV show Saturday Night Live. YouTubers reveals how YouTube saw off its emerging rivals in the online video battle of the 2000s and was bought by the search engine specialist Google. With Google's billions and boosted by smartphones, YouTube became the dominant video platform. Bloggers started to create engaging, fast-cut videos that capitalised on the intimate relationship between creator and user – a 'parasocial' relationship stronger than the bond between TV presenter and viewer. By ceaselessly urging their followers to tap the like, comment and subscribe buttons, these creators helped YouTube's rise to global domination. YouTubers speaks to YouTube stars KSI, Hank and John Green and delves into the lives of child star MattyB, the training camp for aspiring teenage bloggers, the YouTube stunts that go wrong and the increasing efforts of creators to earn money from Patreon. And it tackles the platform's Muslim extremism, red-pilling, and its content guidelines and censorship. YouTubers asks how YouTube can take on the threat from other big platforms such as Instagram and Facebook. In short, YouTubers tells the riveting story of the exponential growth of YouTube from single home video to global tech phenomenon. It is the best and only book you need to read on YouTube. Extract Introduction One spring afternoon Casey Neistat uploaded a video lasting five minutes and twenty-two seconds to YouTube. In the style of so many YouTubers, he looked straight into the camera and aired his opinion on a matter of importance. As the elder statesman on the platform, Neistat’s words carry weight. He can make or break products and careers — and this video was no different. Seconds after he uploaded his video to YouTube via his superfast broadband at his creative headquarters in New York, it was available worldwide to four billion people: everyone on Earth with an internet connection. Millions of Neistat’s subscribers instantly received a notification telling them that one of YouTube’s most influential stars was again speaking directly to them. Across the world in apartment blocks, restaurants, bedrooms and bathrooms, phones pinged, buzzed and beeped. Hundreds of thousands of people instantly watched what Neistat had to say. Wearing dark glasses, his hair streaked blond, Neistat vented his frustration at the way the media was second-guessing the motivations of YouTubers; and he wanted to single out one journalist in particular. In the comments section underneath his video his fans began discussing the question he posed: did people post videos on YouTube for the fame and fortune — or just to express themselves? YouTube is a kaleidoscope of visual and audio content that mimics the richness, quirkiness, beauty and madness of human life. Every day its users upload videos on everything from pop music to politics, fashion to plumbing, and cars to fishing. The topics are as diverse (and as random) as the world itself. Want to watch racing pigeons, cut a perfect bob, discuss Che Guevara, speak Mandarin, or play guitar? YouTube can offer that, instantly. Want to relax while seeing boiled sweets made the old-fashioned way? Load up Lofty Pursuits. Have a hankering to watch a man meticulously scratch away the foil on 200 lottery playing cards to see if he can win back his outlay? Type ‘moorsey scratchcards’ into your search bar and reap the rewards. Whether giving sex advice, posting football clips or simply splicing together footage to create an action-packed vlog, video makers want to communicate with and be seen by YouTube’s 1.9 billion registered users. Some hope that, like Casey Neistat, they too will one day set off pings across the world. For a few, notifications mean that millions of fans are watching them and their view counters are whirring upwards, along with their bank balances. Elite influencers are creative and dynamic and get to do what they want all day long. Unsurprisingly, becoming a YouTuber is the job children most covet. They understand the platform’s extraordinary growth. YouTube is expanding so fast that outsiders can’t accurately measure its size. An estimated 576,000 hours of video are added daily to YouTube – vastly more than the new releases on Netflix. In October, November and December 2018, Netflix added 781 hours of original content, while 53 million hours of footage likely went onto YouTube. It would take you 35 days to watch the new Netflix content non-stop. You’d still be watching the YouTube uploads in the year 8069. YouTube’s rise has been swift. In little more than a decade, it has moved from an oddity broadcast on bulky grey computer monitors to mass media entertainment viewed on ultra-thin, wall-mounted 55-inch televisions. In the past five years, YouTube viewing has rocketed from 100 million hours a day to one billion hours a day. Buy the book and carry one reading
