Wireless Technology Prospects and Policy Options
by National Research Council of the National AcademiesThe use of radio-frequency communication--commonly referred to as wireless communication--is becoming more pervasive as well as more economically and socially important. Technological progress over many decades has enabled the deployment of several successive generations of cellular telephone technology, which is now used by many billions of people worldwide; the near-universal addition of wireless local area networking to personal computers; and a proliferation of actual and proposed uses of wireless communications. The flood of new technologies, applications, and markets has also opened up opportunities for examining and adjusting the policy framework that currently governs the management and use of the spectrum and the institutions involved in it, and models for allocating spectrum and charging for it have come under increasing scrutiny. Yet even as many agree that further change to the policy framework is needed, there is debate about precisely how the overall framework should be changed, what trajectory its evolution should follow, and how dramatic or rapid the change should be. Many groups have opinions, positions, demands, and desires related to these questions--reflecting multiple commercial, social, and political agendas and a mix of technical, economic, and social perspectives. The development of technologies and associated policy and regulatory regimes are often closely coupled, an interplay apparent as early as the 1910s, when spectrum policy emerged in response to the growth of radio communications. As outlined in this report, current and ongoing technological advances suggest the need for a careful reassessment of the assumptions that inform spectrum policy in the United States today. This book seeks to shine a spotlight on 21st-century technology trends and to outline the implications of emerging technologies for spectrum management in ways that the committee hopes will be useful to those setting future spectrum policy.

The Wires of War: Technology and the Global Struggle for Power
by Jacob HelbergFrom the former news policy lead at Google, an urgent and groundbreaking account of the high-stakes global cyberwar brewing between Western democracies and the autocracies of China and Russia that could potentially crush democracy.From 2016 to 2020, Jacob Helberg led Google&’s global internal product policy efforts to combat disinformation and foreign interference. During this time, he found himself in the midst of what can only be described as a quickly escalating two-front technology cold war between democracy and autocracy. On the front-end, we&’re fighting to control the software—applications, news information, social media platforms, and more—of what we see on the screens of our computers, tablets, and phones, a clash which started out primarily with Russia but now increasingly includes China and Iran. Even more ominously, we&’re also engaged in a hidden back-end battle—largely with China—to control the Internet&’s hardware, which includes devices like cellular phones, satellites, fiber-optic cables, and 5G networks. This tech-fueled war will shape the world&’s balance of power for the coming century as autocracies exploit twenty-first-century methods to re-divide the world into twentieth century-style spheres of influence. Helberg cautions that the spoils of this fight are power over every meaningful aspect of our lives, including our economy, our infrastructure, our national security, and ultimately, our national sovereignty. Without a firm partnership with the government, Silicon Valley is unable to protect democracy from the autocrats looking to sabotage it from Beijing to Moscow and Tehran. The stakes of the ongoing cyberwar are no less than our nation&’s capacity to chart its own future, the freedom of our democratic allies, and even the ability of each of us to control our own fates, Helberg says. And time is quickly running out.

Wise Guy: Lessons from a Life
by Guy KawasakiSilicon Valley icon and bestselling author Guy Kawasaki shares the unlikely stories of his life and the lessons we can draw from them.Guy Kawasaki has been a fixture in the tech world since he was part of Apple's original Macintosh team in the 1980s. He's widely respected as a source of wisdom about entrepreneurship, venture capital, marketing, and business evangelism, which he's shared in bestselling books such as The Art of the Start and Enchantment. But before all that, he was just a middle-class kid in Hawaii, a grandson of Japanese immigrants, who loved football and got a C+ in 9th grade English. Wise Guy, his most personal book, is about his surprising journey. It's not a traditional memoir but a series of vignettes. He toyed with calling it Miso Soup for the Soul, because these stories (like those in the Chicken Soup series) reflect a wide range of experiences that have enlightened and inspired him. For instance, you'll follow Guy as he . . . * Gets his first real job in the jewelry business--which turned out to be surprisingly useful training for the tech world. * Disparages one of Apple's potential partners in front of that company's CEO, at the sneaky instigation of Steve Jobs. * Blows up his Apple career with a single sentence, after Jobs withholds a pre-release copy of the Think Different ad campaign: "That's okay, Steve, I don't trust you either." * Reevaluates his self-importance after being mistaken for Jackie Chan by four young women. * Takes up surfing at age 62--which teaches him that you can discover a new passion at any age, but younger is easier!Guy covers everything from moral values to business skills to parenting. As he writes, "I hope my stories help you live a more joyous, productive, and meaningful life. If Wise Guy succeeds at this, then that's the best story of all."
Wissen als Handlungsoption: Zum Zusammenspiel von menschlicher und künstlicher Intelligenz in der Rechtsindustrie (essentials)

Nur, wer den Markt kennt und weiß, welche Probleme Kunden haben und wie diese sich mit neuen Produkten und Services lösen lassen, kann erfolgreich agieren. Dieses Buch untersucht die Auswirkungen der Digitalisierung auf die Rolle des Wissens in der Rechtsbranche. In Rechtsabteilungen und Kanzleien wandelt sich Wissen zunehmend von einem statischen Vorrats-Wissen zu einem dynamischen Ad-Hoc-Wissen, das durch den Einsatz von Software-Anwendungen bedarfsgerecht erzeugt wird und dem Erreichen eines bestimmten Zwecks dient. Dabei ist immer der jeweilige Geschäftskontext entscheidend für die Einsicht, was wie zu tun ist. Für Anwälte und alle, die an juristischen Transaktionen in Unternehmen beteiligt sind, bedeutet dies nicht nur, dass sie die allgemeinen Chancen und Risiken der digitalen Transformation kennen müssen. Sie müssen auch verstehen, wie sie neue Technologien dafür nutzen können, ihre eigene Kreativität zu stärken, informierte Entscheidungen zu treffen und im Team kooperativ zu einem gemeinsamen Ziel zu gelangen.

Wissenschaft kommuniziert: Eine wissenssoziologische Gattungsanalyse des akademischen Group-Talks am Beispiel der Computational Neuroscience (Wissen, Kommunikation und Gesellschaft)
by René WilkeIn diesem Open-Access-Buch steht der akademische Group-Talk als Format der wissenschaftsinternen Wissenskommunikation im Fokus. Group-Talk ist die Feldbezeichnung für das wöchentliche Arbeitstreffen einer teilnehmend beobachteten Forschungsgruppe in der Computational Neuroscience (CNS). Dass (soziale) Wirklichkeit in Interaktionsprozessen erzeugt und institutionalisiert wird, ist eine aus der Wissenssoziologie bzw. dem Sozialkonstruktivismus bereits wohlbekannte Erkenntnis. Dass diese Erzeugung maßgeblich durch kommunikatives Handeln prozessiert wird, ist spätestens seit dem Kommunikativen Konstruktivismus bekannt. Zentral in vorliegender Analyse ist daher die spezifische Form des kommunikativen Handelns, das besondere Format, in dem die CNS, als relativ junger und interdisziplinärer Forschungskontext, von den disziplinär heterogenen Wissenschaftler/-innen im Feld, kommunikativ (re-)konstruiert wird. Die wissenssoziologische Gattungsanalyse dient dabei dazu, den reinen Situationalismus zu überschreiten und die soziologische Mikroanalyse (Handeln), vor dem Hintergrund einer fokussiert-ethnographischen Feldstudie, mit gesellschaftlichen Emergenzphänomenen auf Meso- und Makroebene zu verknüpfen. Erst diese systematische Verbindung des direkt beobachtbaren Wie der Kommunikation mit dem durch ethnographisches Wissen rekonstruierten Warum, überschreitet den Horizont reiner Beschreibung und führt in die Bereiche des soziologischen Verstehens und Erklärens.
