| engenius durafon pro manual: Where the Jobs Are John Dearie, Courtney Geduldig, 2013-08-28 A guide to ending America's jobs emergency by accelerating the true engine of job creation—start-ups Four years after the end of the Great Recession, 23 million Americans remain unemployed, underemployed, or have left the workforce discouraged. Even worse, Washington policymakers seem out of ideas. Where the Jobs Are: Entrepreneurship and the Soul of the American Economy shows how America can restore its great job-creation machine. Recent research has demonstrated that virtually all net new job creation in the United States over the past thirty years has come from businesses less than a year old—true start-ups. Start-up businesses create an average of three million new jobs each year, while existing businesses of any size or age shed a net average of about one million jobs annually. Unfortunately, the vital signs of America's job-creating entrepreneurial economy are flashing red alert. After remaining remarkably consistent for decades, the rate of new business formation has declined significant in recent years, and the number of new jobs created by new firms is also falling. In Where the Jobs Are, the authors recount the findings of a remarkable summer they spent traveling the country to meet and conduct roundtables with entrepreneurs in a dozen cities. More than 200 entrepreneurs participated—explaining in specific and vividly personal terms the issues, frustrations, and obstacles that are undermining their efforts to launch new businesses, expand existing young firms, and create jobs. Those obstacles include a dangerously underperforming education system, self-defeating immigration policies that thwart the attraction and retention of the world's best talent, access to capital difficulties, a mounting regulatory burden, unnecessary tax complexity, and severe Washington-produced economic uncertainty. Explains how start-ups are different from existing businesses, large or small, and why they represent the engine of job creation Reveals how policymakers' failure to understand the unique nature and needs of start-ups has undermined efforts to stimulate the economy following the Great Recession Presents a detailed, innovative, and uniquely credible 30-point policy agenda based on what America's job creators said they urgently need Engaging and informative, Where the Jobs Are reveals with unprecedented precision and clarity the major obstacles undermining the fragile economic recovery, and provides a vitally important game plan to unleash the job-creating capacity of the entrepreneurial economy and put a beleaguered nation back to work. |
| engenius durafon pro manual: The U.S. Technology Skills Gap Gary J. Beach, 2013-07-10 Is a widening “skills gap” in science and math education threatening America’s future? That is the seminal question addressed in The U.S. Technology Skills Gap, a comprehensive 104-year review of math and science education in America. Some claim this “skills gap” is “equivalent to a permanent national recession” while others cite how the gap threatens America’s future economic, workforce employability and national security. This much is sure: America’s math and science skills gap is, or should be, an issue of concern for every business and information technology executive in the United States and The U.S Technology Skills Gap is the how-to-get involved guidebook for those executives laying out in a compelling chronologic format: The history of the science and math skills gap in America Explanation of why decades of astute warnings were ignored Inspiring examples of private company efforts to supplement public education A pragmatic 10-step action plan designed to solve the problem And a tantalizing theory of an obscure Japanese physicist that suggests America’s days as the global scientific leader are numbered Engaging and indispensable, The U.S. Technology Skills Gap is essential reading for those eager to see America remain a relevant global power in innovation and invention in the years ahead. |
| engenius durafon pro manual: Ninja Innovation Gary Shapiro, 2013-01-08 Innovate or die For thirty years, Gary Shapiro has observed the world's most innovative businesses from his front-row seat as leader of the Consumer Electronics Association. Now he reveals the ten secrets of ninja innovators like Apple, Amazon, Google, Microsoft, and many others. What does it take to succeed? Discipline. Mission-oriented strategy. Adaptability. Decisiveness. And a will for victory. In short, today's most successful businesses are ninja innovators. Drawn from Gary Shapiro's three decades of experience leading the consumer electronics industry, Ninja Innovation takes readers behind the scenes of today's top enterprises, uncovering their ten essential strategies for success. As head of the Consumer Electronics Association and its influential annual trade show, the International CES, Shapiro has worked with the most innovative companies in history—Intel, IBM, and Samsung, to name a few—focusing on creating policies and events that produce revolutionary products year after year. He has learned the key strategies that have guided these businesses to record-breaking profits, as well as the traps that have led so many others to crushing failure. In order to stay in front of the pace of innovation, Shapiro observes, top companies must operate as an elite strike force—just like the legendary medieval warriors known as ninjas. Ninjas weren't called upon to do the ordinary; they had to perform truly extraordinary tasks, while risking everything. As a highly trained martial-arts black belt himself, Shapiro mines the valuable insights of these centuries-old warriors to spotlight the secrets of agility, creativity, decisiveness, and reinvention that are essential for twenty-first-century leaders seeking breakthrough success. Taking readers inside the most cutting-edge businesses, Ninja Innovation is the ultimate guide to achieving victory in today's innovate-or-die economy. |
| engenius durafon pro manual: Big Bang Disruption Larry Downes, Paul Nunes, 2014-01-07 It used to take years or even decades for disruptive innovations to dethrone dominant products and services. But now any business can be devastated virtually overnight by something better and cheaper. How can executives protect themselves and harness the power of Big Bang Disruption? Just a few years ago, drivers happily spent more than $200 for a GPS unit. But as smartphones exploded in popularity, free navigation apps exceeded the performance of stand-alone devices. Eighteen months after the debut of the navigation apps, leading GPS manufacturers had lost 85 percent of their market value. Consumer electronics and computer makers have long struggled in a world of exponential technology improvements and short product life spans. But until recently, hotels, taxi services, doctors, and energy companies had little to fear from the information revolution. Those days are gone forever. Software-based products are replacing physical goods. And every service provider must compete with cloud-based tools that offer customers a better way to interact. Today, start-ups with minimal experience and no capital can unravel your strategy before you even begin to grasp what’s happening. Never mind the “innovator’s dilemma”—this is the innovator’s disaster. And it’s happening in nearly every industry. Worse, Big Bang Disruptors may not even see you as competition. They don’t share your approach to customer service, and they’re not sizing up your product line to offer better prices. You may simply be collateral damage in their efforts to win completely different markets. The good news is that any business can master the strategy of the start-ups. Larry Downes and Paul Nunes analyze the origins, economics, and anatomy of Big Bang Disruption. They identify four key stages of the new innovation life cycle, helping you spot potential disruptors in time. And they offer twelve rules for defending your markets, launching disruptors of your own, and getting out while there’s still time. Based on extensive research by the Accenture Institute for High Performance and in-depth interviews with entrepreneurs, investors, and executives from more than thirty industries, Big Bang Disruption will arm you with strategies and insights to thrive in this brave new world. |
| engenius durafon pro manual: Finding the Next Steve Jobs Nolan Bushnell, Gene Stone, 2013-07-16 From the legendary founder of Atari and Chuck E. Cheese’s and Steve Jobs’s first boss, the secrets to finding, hiring, keeping, and nurturing creative talent. The business world is changing faster than ever, and every day your company faces new complications and difficulties. The only way to resolve these issues is to have a staff of wildly creative people who live as much in the future as the present, who thrive on being different, and whose ideas will guarantee that your company will prosper when other companies fail. A celebrated visionary and iconoclast, Nolan Bushnell founded the groundbreaking gaming company Atari before he went on to found Chuck E. Cheese’s and two dozen other companies. He also happened to launch the career of the late Steve Jobs, along with those of many other brilliant creatives over the course of his five decades in business. With refreshing candor, keen psychological insight, and robust humor, Bushnell explains in Finding the Next Steve Jobs how to think boldly and differently about companies and organizations—and specifically the people who work within them. For anyone trying to turn a company into the next Atari or Apple, build a more creative workforce, or fashion a career in a changing world, this book will enlighten, challenge, surprise, and amuse. |
| engenius durafon pro manual: Age of Context Robert Scoble, Shel Israel, 2014 In 2006, co-authors Robert Scoble and Shel Israel wrote Naked Conversations, a book that persuaded businesses to embrace what we now call social media. Six years later they have teamed up again to report that social media is but one of five converging forces that promise to change virtually every aspect of our lives. You know these other forces already: mobile, data, sensors and location-based technology. Combined with social media they form a new generation of personalized technology that knows us better than our closest friends. Armed with that knowledge our personal devices can anticipate what we'll need next and serve us better than a butler or an executive assistant. The resulting convergent superforce is so powerful that it is ushering in a era the authors call the Age of Context. In this new era, our devices know when to wake us up early because it snowed last night; they contact the people we are supposed to meet with to warn them we're running late. They even find content worth watching on television. They also promise to cure cancer and make it harder for terrorists to do their damage. Astoundingly, in the coming age you may only receive ads you want to see. Scoble and Israel have spent more than a year researching this book. They report what they have learned from interviewing more than a hundred pioneers of the new technology and by examining hundreds of contextual products. What does it all mean? How will it change society in the future? The authors are unabashed tech enthusiasts, but as they write, an elephant sits in the living room of our book and it is called privacy. We are entering a time when our technology serves us best because it watches us; collecting data on what we do, who we speak with, what we look at. There is no doubt about it: Big Data is watching you. The time to lament the loss of privacy is over. The authors argue that the time is right to demand options that enable people to reclaim some portions of that privacy. |
| engenius durafon pro manual: Open Source Geospatial Science for Urban Studies Amin Mobasheri, 2020-09-07 This book is mainly focused on two themes: transportation and smart city applications. Open geospatial science and technology is an increasingly important paradigm that offers the opportunity to promote the democratization of geographical information, the transparency of governments and institutions, as well as social, economic and urban opportunities. During the past decade, developments in the area of open geospatial data have greatly increased. The open source GIS research community believes that combining free and open software, open data, as well as open standards, leads to the creation of a sustainable ecosystem for accelerating new discoveries to help solve global cross-disciplinary urban challenges. The vision of this book is to enrich the existing literature on this topic, and act one step towards more sustainable cities through employment of open source GIS solutions that are reproducible. Various contributions are provided and practically implemented in several urban use cases. Therefore, apart from researchers, lecturers and students in the geography/urbanism domain, crowdsourcing and VGI domain, as well as open source GIS domain, it is believed the specialists and mentors in municipalities and urban planning departments as well as professionals in private companies would be interested to read this book. |
| engenius durafon pro manual: How Open Source Ate Software Gordon Haff, 2018-08-21 Learn how free software became open source and how you can sell open source software. This book provides a historical context of how open source has thoroughly transformed how we write software, how we cooperate, how we communicate, how we organize, and, ultimately, how we think about business values. You’ll look at project and community examples including Linux, BSD, Apache, and Kubernetes, understand the open source development model, and how open source has influenced approaches more broadly, even proprietary software, such as open betas. You'll also examine the flipside, the Second Machine Age, and the challenges of open source-based business models. Today, open source serves as shorthand for much broader trends and behaviors. It’s not just about a free (in all senses of the word) alternative to commercial software. It increasingly is the new commercial software. How Open Source Ate Software reveals how open source has much in common, and is often closely allied, with many other trends in business and society. You'll see how it enables projects that go beyond any individual company. That makes open source not just a story about software, but a story about almost everything. What You'll Learn Understand open source opportunities and challenges Sell software if you’re giving it away Apply open source principles more broadly to openorg, devops, etc. Review which organizational incentives you can implement Who This Book Is For Anyone who has an interest in what is happening in open source and the open source community, and anyone who is contemplating making a business that involves open source. |
