Book Description
We depend on information and information technology (IT) to make many of our day-to-day tasks easier and more convenient. Computers play key roles in transportation, health care, banking, and energy. Businesses use IT for payroll and accounting, inventory and sales, and research and development. Modern military forces use weapons that are increasingly coordinated through computer-based networks. Cybersecurity is vital to protecting all of these functions. Cyberspace is vulnerable to a broad spectrum of hackers, criminals, terrorists, and state actors. Working in cyberspace, these malevolent actors can steal money, intellectual property, or classified information; impersonate law-abiding parties for their own purposes; damage important data; or deny the availability of normally accessible services. Cybersecurity issues arise because of three factors taken together - the presence of malevolent actors in cyberspace, societal reliance on IT for many important functions, and the presence of vulnerabilities in IT systems. What steps can policy makers take to protect our government, businesses, and the public from those would take advantage of system vulnerabilities? At the Nexus of Cybersecurity and Public Policy offers a wealth of information on practical measures, technical and nontechnical challenges, and potential policy responses. According to this report, cybersecurity is a never-ending battle; threats will evolve as adversaries adopt new tools and techniques to compromise security. Cybersecurity is therefore an ongoing process that needs to evolve as new threats are identified. At the Nexus of Cybersecurity and Public Policy is a call for action to make cybersecurity a public safety priority. For a number of years, the cybersecurity issue has received increasing public attention; however, most policy focus has been on the short-term costs of improving systems. In its explanation of the fundamentals of cybersecurity and the discussion of potential policy responses, this book will be a resource for policy makers, cybersecurity and IT professionals, and anyone who wants to understand threats to cyberspace.

Book Description
A new way of understanding the essence of moral obligation The Moral Nexus develops and defends a new interpretation of morality—namely, as a set of requirements that connect agents normatively to other persons in a nexus of moral relations. According to this relational interpretation, moral demands are directed to other individuals, who have claims that the agent comply with these demands. Interpersonal morality, so conceived, is the domain of what we owe to each other, insofar as we are each persons with equal moral standing. The book offers an interpretative argument for the relational approach. Specifically, it highlights neglected advantages of this way of understanding the moral domain; explores important theoretical and practical presuppositions of relational moral duties; and considers the normative implications of understanding morality in relational terms. The book features a novel defense of the relational approach to morality, which emphasizes the special significance that moral requirements have, both for agents who are deliberating about what to do and for those who stand to be affected by their actions. The book argues that relational moral requirements can be understood to link us to all individuals whose interests render them vulnerable to our agency, regardless of whether they stand in any prior relationship to us. It also offers fresh accounts of some of the moral phenomena that have seemed to resist treatment in relational terms, showing that the relational interpretation is a viable framework for understanding our specific moral obligations to other people.

Book Description
The stunning sequel to NEXUS Six months have passed since the release of Nexus 5. The world is a different, more dangerous place. In the United States, the terrorists - or freedom fighters - of the Post-Human Liberation Front use Nexus to turn men and women into human time bombs aimed at the President and his allies. In Washington DC, a government scientist, secretly addicted to Nexus, uncovers more than he wants to know about the forces behind the assassinations, and finds himself in a maze with no way out. In Thailand, Samantha Cataranes has found peace and contentment with a group of children born with Nexus in their brains. But when forces threaten to tear her new family apart, Sam will stop at absolutely nothing to protect the ones she holds dear. In Vietnam, Kade and Feng are on the run from bounty hunters seeking the price on Kade's head, from the CIA, and from forces that want to use the back door Kade has built into Nexus 5. Kade knows he must stop the terrorists misusing Nexus before they ignite a global war between human and posthuman. But to do so, he'll need to stay alive and ahead of his pursuers. And in Shanghai, a posthuman child named Ling Shu will go to dangerous and explosive lengths to free her uploaded mother from the grip of Chinese authorities. The first blows in the war between human and posthuman have been struck. The world will never be the same. File Under: Science Fiction [ Upgraded | Closer Than You Think | Upload | Civil War ] Praise for Book 1: NEXUS:"The only serious successor to Michael Crichton." - Scott Harrison, author of Archangel "Good. Scary Good." - Wired "One of the Best Books of 2013"- NPR "Provocative. A double-edged vision of the post-human." - The Wall Street Journal "Starred Review. Naam turns in a stellar performance in his debut SF novel. What matters here is the remarkable scope and narrative power of the story." - Booklist "A gripping piece of near future speculation... all the grit and pace of the Bourne films." - Alastair Reynolds, author of Revelation Space "A lightning bolt of a novel, with a sense of awe missing from a lot of current fiction." -Ars Technica "A rich cast of characters...the action scenes are crisp, the glimpses of future tech and culture are mesmerizing." - Publishers Weekly "Read it before everyone's talking about it." - John Barnes Praise for Book 2: CRUX: "A blisteringly paced technothriller that dives deeper and even better into the chunky questions raised by Nexus. This is a fabulous book, and it ends in a way that promises at least one more. Count me in." - Cory Doctorow, author of Little Brother "Nexus and Crux are a devastating look into the political consequences of transhumanism; a sharp, chilling look at our likely future." - Charles Stross "Smart, thoughtful, and hard to drop, this richly nuanced sequel outshines its predecessor." - Publishers Weekly "A heady cocktail of ideas and page-turning prose. It left my brain buzzing for days afterwards." - Hannu Rajaniemi, author of The Quantum Thief "Highly recommended for preparation of the future revolution." - Harper Reed, Former CTO, Obama for America

Book Description
In 2005, Americans paid about $2.1 trillion in combined federal taxes, including income, payroll, and excise taxes, or about 16.8 percent of the Gross Domestic Product (GDP). These taxes fund the services provided by government. As taxpayers, we balance the costs of taxes with the benefits of government. The goal of tax policy is to design a tax system that produces the desired amount of revenue and balances the minimisation of compliance and efficiency costs with other objectives, such as equity, transparency, and administrability. This book examines the detail which is where vested interests do their damage.

Book Description
How the West sleepwalked into another Cold War A native of Yalta, Constantine Pleshakov is intimately familiar with Crimea s ethnic tensions and complex political history. Now, he offers a much-needed look at one of the most urgent flash points in current international relations: the first occupation and annexation of one European nation s territory by another since World War II. Pleshakov illustrates how the proxy war unfolding in Ukraine is a clash of incompatible world views. To the U.S. and Europe, Ukraine is a country struggling for self-determination in the face of Russia s imperial nostalgia. To Russia, Ukraine is a sister nation, where NATO expansionism threatens its own borders. In Crimea itself, the native Tatars are Muslims who are vehemently opposed to Russian rule. Engagingly written and bracingly nonpartisan, Pleshakov s book explains the missteps made on all sides to provide a clear, even-handed account of a major international crisis.
