Reports on a new generation of Internet controls that establish a new normative terrain in which surveillance and censorship are routine. Internet filtering, censorship of Web content, and online surveillance are increasing in scale, scope, and sophistication around the world, in democratic countries as well as in authoritarian states. The first generation of Internet controls consisted largely of building firewalls at key Internet gateways; China's famous “Great Firewall of China” is one of the first national Internet filtering systems. Today the new tools for Internet controls that are emerging go beyond mere denial of information. These new techniques, which aim to normalize (or even legalize) Internet control, include targeted viruses and the strategically timed deployment of distributed denial-of-service (DDoS) attacks, surveillance at key points of the Internet's infrastructure, take-down notices, stringent terms of usage policies, and national information shaping strategies. Access Controlled reports on this new normative terrain. The book, a project from the OpenNet Initiative (ONI), a collaboration of the Citizen Lab at the University of Toronto's Munk Centre for International Studies, Harvard's Berkman Center for Internet and Society, and the SecDev Group, offers six substantial chapters that analyze Internet control in both Western and Eastern Europe and a section of shorter regional reports and country profiles drawn from material gathered by the ONI around the world through a combination of technical interrogation and field research methods.

Experts examine censorship, surveillance, and resistance across Asia, from China and India to Malaysia and the Philippines. A daily battle for rights and freedoms in cyberspace is being waged in Asia. At the epicenter of this contest is China—home to the world's largest Internet population and what is perhaps the world's most advanced Internet censorship and surveillance regime in cyberspace. Resistance to China's Internet controls comes from both grassroots activists and corporate giants such as Google. Meanwhile, similar struggles play out across the rest of the region, from India and Singapore to Thailand and Burma, although each national dynamic is unique. Access Contested, the third volume from the OpenNet Initiative (a collaborative partnership of the Citizen Lab at the University of Toronto's Munk School of Global Affairs, the Berkman Center for Internet and Society at Harvard University, and the SecDev Group in Ottawa), examines the interplay of national security, social and ethnic identity, and resistance in Asian cyberspace, offering in-depth accounts of national struggles against Internet controls as well as updated country reports by ONI researchers. The contributors examine such topics as Internet censorship in Thailand, the Malaysian blogosphere, surveillance and censorship around gender and sexuality in Malaysia, Internet governance in China, corporate social responsibility and freedom of expression in South Korea and India, cyber attacks on independent Burmese media, and distributed-denial-of-service attacks and other digital control measures across Asia.

A study of Internet blocking and filtering around the world: analyses by leading researchers and survey results that document filtering practices in dozens of countries. Many countries around the world block or filter Internet content, denying access to information that they deem too sensitive for ordinary citizens—most often about politics, but sometimes relating to sexuality, culture, or religion. Access Denied documents and analyzes Internet filtering practices in more than three dozen countries, offering the first rigorously conducted study of an accelerating trend. Internet filtering takes place in more than three dozen states worldwide, including many countries in Asia, the Middle East, and North Africa. Related Internet content-control mechanisms are also in place in Canada, the United States and a cluster of countries in Europe. Drawing on a just-completed survey of global Internet filtering undertaken by the OpenNet Initiative (a collaboration of the Berkman Center for Internet and Society at Harvard Law School, the Citizen Lab at the University of Toronto, the Oxford Internet Institute at Oxford University, and the University of Cambridge) and relying on work by regional experts and an extensive network of researchers, Access Denied examines the political, legal, social, and cultural contexts of Internet filtering in these states from a variety of perspectives. Chapters discuss the mechanisms and politics of Internet filtering, the strengths and limitations of the technology that powers it, the relevance of international law, ethical considerations for corporations that supply states with the tools for blocking and filtering, and the implications of Internet filtering for activist communities that increasingly rely on Internet technologies for communicating their missions. Reports on Internet content regulation in forty different countries follow, with each two-page country profile outlining the types of content blocked by category and documenting key findings.

Media scholars, artists, activists, and journalists discuss how the uses of the emerging “Social Web” redefine the public sphere and influence mainstream journalism. In an age of proliferating media and news sources, who has the power to define reality? When the dominant media declared the existence of WMDs in Iraq, did that make it a fact? Today, the “Social Web” (sometimes known as Web 2.0, groupware, or the participatory web)—epitomized by blogs, viral videos, and YouTube—creates new pathways for truths to emerge and makes possible new tactics for media activism. In Digital Media and Democracy , leading scholars in media and communication studies, media activists, journalists, and artists explore the contradiction at the heart of the relationship between truth and power today: the fact that the radical democratization of knowledge and multiplication of sources and voices made possible by digital media coexists with the blatant falsification of information by political and corporate powers. The book maps a new digital media landscape that features citizen journalism, The Daily Show, blogging, and alternative media. The contributors discuss broad questions of media and politics, offer nuanced analyses of change in journalism, and undertake detailed examinations of the use of web-based media in shaping political and social movements. The chapters include not only essays by noted media scholars but also interviews with such journalists and media activists as Amy Goodman of Democracy Now!, Media Matters host Robert McChesney, and Hassan Ibrahim of Al Jazeera. Contributors and Interviewees Shaina Anand, Chris Atton, Megan Boler, Axel Bruns, Jodi Dean, Ron Deibert, Deepa Fernandes, Amy Goodman, Brian Holmes, Hassan Ibrahim, Geert Lovink, Nathalie Magnan, Robert McChesney, Graham Meikle, Susan Moeller, Alessandra Renzi, Ricardo Rosas, Trebor Scholz, D.

An examination of the ways cyberspace is changing both the theory and the practice of international relations. Cyberspace is widely acknowledged as a fundamental fact of daily life in today's world. Until recently, its political impact was thought to be a matter of low politics—background conditions and routine processes and decisions. Now, however, experts have begun to recognize its effect on high politics—national security, core institutions, and critical decision processes. In this book, Nazli Choucri investigates the implications of this new cyberpolitical reality for international relations theory, policy, and practice. The ubiquity, fluidity, and anonymity of cyberspace have already challenged such concepts as leverage and influence, national security and diplomacy, and borders and boundaries in the traditionally state-centric arena of international relations. Choucri grapples with fundamental questions of how we can take explicit account of cyberspace in the analysis of world politics and how we can integrate the traditional international system with its cyber venues. After establishing the theoretical and empirical terrain, Choucri examines modes of cyber conflict and cyber cooperation in international relations; the potential for the gradual convergence of cyberspace and sustainability, in both substantive and policy terms; and the emergent synergy of cyberspace and international efforts toward sustainable development. Choucri's discussion is theoretically driven and empirically grounded, drawing on recent data and analyzing the dynamics of cyberpolitics at individual, state, international, and global levels.

An argument that the movement for network neutrality was of a piece with its neoliberal environment, solidifying the continued existence of a commercially driven internet. Media reform activists rejoiced in 2015 when the FCC codified network neutrality, approving a set of Open Internet rules that prohibitedproviders from favoring some content and applications over others—only to have their hopes dashed two years later when the agency reversed itself. In this book, Russell Newman offers a unique perspective on these events, arguing that the movement for network neutrality was of a piece with its neoliberal environment rather than counter to it; perversely, it served to solidify the continued existence of a commercially dominant internet and even emergent modes of surveillance and platform capitalism. Going beyond the usual policy narrative of open versus closed networks, or public interest versus corporate power, Newman uses network neutrality as a lens through which to examine the ways that neoliberalism renews and reconstitutes itself, the limits of particular forms of activism, and the shaping of future regulatory processes and policies. Newman explores the debate's roots in the 1990s movement for open access, the transition to network neutrality battles in the 2000s, and the terms in which these battles were fought. By 2017, the debate had become unmoored from its own origins, and an emerging struggle against “neoliberal sincerity” points to a need to rethink activism surrounding media policy reform itself.

The case for a smarter “prosumer law” approach to Internet regulation that would better protect online innovation, public safety, and fundamental democratic rights. Internet use has become ubiquitous in the past two decades, but governments, legislators, and their regulatory agencies have struggled to keep up with the rapidly changing Internet technologies and uses. In this groundbreaking collaboration, regulatory lawyer Christopher Marsden and computer scientist Ian Brown analyze the regulatory shaping of “code”—the technological environment of the Internet—to achieve more economically efficient and socially just regulation. They examine five “hard cases” that illustrate the regulatory crisis: privacy and data protection; copyright and creativity incentives; censorship; social networks and user-generated content; and net neutrality. The authors describe the increasing “multistakeholderization” of Internet governance, in which user groups argue for representation in the closed business-government dialogue, seeking to bring in both rights-based and technologically expert perspectives. Brown and Marsden draw out lessons for better future regulation from the regulatory and interoperability failures illustrated by the five cases. They conclude that governments, users, and better functioning markets need a smarter “prosumer law” approach. Prosumer law would be designed to enhance the competitive production of public goods, including innovation, public safety, and fundamental democratic rights.

A biography of Tor—a cultural and technological history of power, privacy, and global politics at the internet's core. Tor, one of the most important and misunderstood technologies of the digital age, is best known as the infrastructure underpinning the so-called Dark Web. But the real “dark web,” when it comes to Tor, is the hidden history brought to light in this book: where this complex and contested infrastructure came from, why it exists, and how it connects with global power in intricate and intimate ways. In Tor: From the Dark Web to the Future of Privacy , Ben Collier has written, in essence, a biography of Tor—a cultural and technological history of power, privacy, politics, and empire in the deepest reaches of the internet. The story of Tor begins in the 1990s with its creation by the US Navy's Naval Research Lab, from a convergence of different cultural worlds. Drawing on in-depth interviews with designers, developers, activists, and users, along with twenty years of mailing lists, design documents, reporting, and legal papers, Collier traces Tor's evolution from those early days to its current operation on the frontlines of global digital power—including the strange collaboration between US military scientists and a group of freewheeling hackers called the Cypherpunks. As Collier charts the rise and fall of three different cultures in Tor's diverse community—the engineers, the maintainers, and the activists, each with a distinct understanding of and vision for Tor—he reckons with Tor's complicated, changing relationship with contemporary US empire. Ultimately, the book reveals how different groups of users have repurposed Tor and built new technologies and worlds of their own around it, with profound implications for the future of the Internet.

Scholars from across law and internet and media studies examine the human rights implications of today's platform society. Today such companies as Apple, Facebook, Google, Microsoft, and Twitter play an increasingly important role in how users form and express opinions, encounter information, debate, disagree, mobilize, and maintain their privacy. What are the human rights implications of an online domain managed by privately owned platforms? According to the Guiding Principles on Business and Human Rights, adopted by the UN Human Right Council in 2011, businesses have a responsibility to respect human rights and to carry out human rights due diligence. But this goal is dependent on the willingness of states to encode such norms into business regulations and of companies to comply. In this volume, contributors from across law and internet and media studies examine the state of human rights in today's platform society. The contributors consider the “datafication” of society, including the economic model of data extraction and the conceptualization of privacy. They examine online advertising, content moderation, corporate storytelling around human rights, and other platform practices. Finally, they discuss the relationship between human rights law and private actors, addressing such issues as private companies' human rights responsibilities and content regulation.

A detailed examination of how the underlying technical structure of the Internet affects the economic environment for innovation and the implications for public policy. Today—following housing bubbles, bank collapses, and high unemployment—the Internet remains the most reliable mechanism for fostering innovation and creating new wealth. The Internet's remarkable growth has been fueled by innovation. In this pathbreaking book, Barbara van Schewick argues that this explosion of innovation is not an accident, but a consequence of the Internet's architecture—a consequence of technical choices regarding the Internet's inner structure that were made early in its history. The Internet's original architecture was based on four design principles: modularity, layering, and two versions of the celebrated but often misunderstood end-to-end arguments. But today, the Internet's architecture is changing in ways that deviate from the Internet's original design principles, removing the features that have fostered innovation and threatening the Internet's ability to spur economic growth, to improve democratic discourse, and to provide a decentralized environment for social and cultural interaction in which anyone can participate. If no one intervenes, network providers' interests will drive networks further away from the original design principles. If the Internet's value for society is to be preserved, van Schewick argues, policymakers will have to intervene and protect the features that were at the core of the Internet's success.

International organizations, governments, academia, industry, and the media have all begun to grapple with the information society as a global policy issue. The first United Nations World Summit on the Information Society (WSIS), held in December 2003, recognized the connections between information technology and human rights with a Declaration of Principles—in effect, the first "constitution" for cyberspace—that called for the development of the information society to conform to recognized standards of human rights. Critical issues in the policy debates around WSIS have been the so-called digital divide, which reflects a knowledge divide, a social divide, and an economic divide; and the need for a nondiscriminatory information society to provide universal access to information technology in local languages throughout the developing world. Other crucial issues include the regulatory frameworks for information access and ownership and such basic freedoms as the right to privacy. The contributors to this timely volume examine the links between information technology and human rights from a range of disciplinary perspectives. Scholars, human rights activists, and practitioners discuss such topics as freedom of expression, access to information, privacy, discrimination, gender equality, intellectual property, political participation, and freedom of assembly in the context of the revolution in information and communication technology, exploring the ways in which the information society can either advance human rights around the world or threaten them. An afterword reports on the November 2005 WSIS, held in Tunis, and its reaffirmation of the fundamental role of human rights in the global information society.

How social networks, the personalized Internet, and always-on mobile connectivity are transforming—and expanding—social life. Daily life is connected life, its rhythms driven by endless email pings and responses, the chimes and beeps of continually arriving text messages, tweets and retweets, Facebook updates, pictures and videos to post and discuss. Our perpetual connectedness gives us endless opportunities to be part of the give-and-take of networking. Some worry that this new environment makes us isolated and lonely. But in Networked , Lee Rainie and Barry Wellman show how the large, loosely knit social circles of networked individuals expand opportunities for learning, problem solving, decision making, and personal interaction. The new social operating system of “networked individualism” liberates us from the restrictions of tightly knit groups; it also requires us to develop networking skills and strategies, work on maintaining ties, and balance multiple overlapping networks. Rainie and Wellman outline the “triple revolution” that has brought on this transformation: the rise of social networking, the capacity of the Internet to empower individuals, and the always-on connectivity of mobile devices. Drawing on extensive evidence, they examine how the move to networked individualism has expanded personal relationships beyond households and neighborhoods; transformed work into less hierarchical, more team-driven enterprises; encouraged individuals to create and share content; and changed the way people obtain information. Rainie and Wellman guide us through the challenges and opportunities of living in the evolving world of networked individuals.

Experts explore current theory and practice in the application of digitally enabled open networked social models to international development. The emergence of open networked models made possible by digital technology has the potential to transform international development. Open network structures allow people to come together to share information, organize, and collaborate. Open development harnesses this power, to create new organizational forms and improve people's lives; it is not only an agenda for research and practice but also a statement about how to approach international development. In this volume, experts explore a variety of applications of openness, addressing challenges as well as opportunities. Open development requires new theoretical tools that focus on real world problems, consider a variety of solutions, and recognize the complexity of local contexts. After exploring the new theoretical terrain, the book describes a range of cases in which open models address such specific development issues as biotechnology research, improving education, and access to scholarly publications. Contributors then examine tensions between open models and existing structures, including struggles over privacy, intellectual property, and implementation. Finally, contributors offer broader conceptual perspectives, considering processes of social construction, knowledge management, and the role of individual intent in the development and outcomes of social models.

Net criticism that establishes the principles and foundation for a collaborative, global new media culture. According to media critic Geert Lovink, the Internet is being closed off by corporations and governments intent on creating a business and information environment free of dissent. Calling himself a radical media pragmatist, Lovink envisions an Internet culture that goes beyond the engineering culture that spawned it to bring humanities, user groups, social movements, nongovernmental organizations (NGOs), artists, and cultural critics into the core of Internet development. In Dark Fiber , Lovink combines aesthetic and ethical concerns and issues of navigation and usability without ever losing sight of the cultural and economic agendas of those who control hardware, software, content, design, and delivery. He examines the unwarranted faith of the cyber-libertarians in the ability of market forces to create a decentralized, accessible communication system. He studies the inner dynamics of hackers' groups, Internet activists, and artists, seeking to understand the social laws of online life. Finally, he calls for the injection of political and economic competence into the community of freedom-loving cyber-citizens, to wrest the Internet from corporate and state control. The topics include the erosion of email, bandwidth for all, the rise and fall of dot-com mania, techno-mysticism, sustainable social networks, the fight for a public Internet time standard, the strategies of Internet activists, mailing list culture, and collaborative text filtering. Stressing the importance of intercultural collaboration, Lovink includes reports from Albania, where NGOs and artists use new media to combat the country's poverty and isolation; from Taiwan, where the September 1999 earthquake highlighted the cultural politics of the Internet; and from Delhi, where a new media center explores free software, public access, and Hindi interfaces.

Making the case that we can use nuclear power to combat climate change even as we reduce the risks of nuclear terror. Humanity faces two existential threats: nuclear annihilation and catastrophic climate change. Both have human origins, and both are linked to the use of nuclear energy. Inherent in the use of atomic fission is the risk that the technology and materials can be diverted to terrorists or hostile nations and used to make nuclear weapons. The key question is whether we can use nuclear energy to reduce the threat of climate change without increasing the risk that nuclear weapons will be used. In Double Jeopardy , Daniel Poneman argues that the world needs an “all-of-the-above” energy policy, one that advances the goal of decarbonizing the environment through all available means—including nuclear power. Poneman makes a compelling case that we can enhance the ability of nuclear power to combat climate change even as we reduce the risks of nuclear terror. Doing so will require well-crafted laws and policies, implemented with an ethos of constant vigilance and embedded in a culture that weaves safety and security goals into the fabric of our nuclear programs. This will enable government and industry to work together to maximize energy and climate benefits while minimizing safety and security risks.

How computer professionals and communities can work together to shape sociotechnical systems that will meet society's challenges. Information and computer technologies are used every day by real people with real needs. The authors contributing to Shaping the Network Society describe how technology can be used effectively by communities, activists, and citizens to meet society's challenges. In their vision, computer professionals are concerned less with bits, bytes, and algorithms and more with productive partnerships that engage both researchers and community activists. These collaborations are producing important sociotechnical work that will affect the future of the network society. Traditionally, academic research on real-world users of technology has been neglected or even discouraged. The authors contributing to this book are working to fill this gap; their theoretical and practical discussions illustrate a new orientation—research that works with people in their natural social environments, uses common language rather than rarefied academic discourse, and takes a pragmatic perspective. The topics they consider are key to democratization and social change. They include human rights in the "global billboard society"; public computing in Toledo, Ohio; public digital culture in Amsterdam; "civil networking" in the former Yugoslavia; information technology and the international public sphere; "historical archaeologies" of community networks; "technobiographical" reflections on the future; libraries as information commons; and globalization and media democracy, as illustrated by Indymedia, a global collective of independent media organizations.

A new approach to nuclear disarmament, nonproliferation, and the prevention of nuclear terrorism that focuses on controlling the production and stockpiling of nuclear materials. Achieving nuclear disarmament, stopping nuclear proliferation, and preventing nuclear terrorism are among the most critical challenges facing the world today. Unmaking the Bomb proposes a new approach to reaching these long-held goals. Rather than considering them as separate issues, the authors—physicists and experts on nuclear security—argue that all three of these goals can be understood and realized together if we focus on the production, stockpiling, and disposal of plutonium and highly enriched uranium—the fissile materials that are the key ingredients used to make nuclear weapons. The authors describe the history, production, national stockpiles, and current military and civilian uses of plutonium and highly enriched uranium, and propose policies aimed at reducing and eventually eliminating these fissile materials worldwide. These include an end to the production of highly enriched uranium and plutonium for weapons, an end to their use as reactor fuels, and the verified elimination of all national stockpiles.

Investigations of how the global Cold War shaped national scientific and technological practices in fields from biomedicine to rocket science. The Cold War period saw a dramatic expansion of state-funded science and technology research. Government and military patronage shaped Cold War technoscientific practices, imposing methods that were project oriented, team based, and subject to national-security restrictions. These changes affected not just the arms race and the space race but also research in agriculture, biomedicine, computer science, ecology, meteorology, and other fields. This volume examines science and technology in the context of the Cold War, considering whether the new institutions and institutional arrangements that emerged globally constrained technoscientific inquiry or offered greater opportunities for it. The contributors find that whatever the particular science, and whatever the political system in which that science was operating, the knowledge that was produced bore some relation to the goals of the nation-state. These goals varied from nation to nation; weapons research was emphasized in the United States and the Soviet Union, for example, but in France and China scientific independence and self-reliance dominated. The contributors also consider to what extent the changes to science and technology practices in this era were produced by the specific politics, anxieties, and aspirations of the Cold War.

Examinations of civic engagement in digital culture—the technologies, designs, and practices that support connection through common purpose in civic, political, and social life. Countless people around the world harness the affordances of digital media to enable democratic participation, coordinate disaster relief, campaign for policy change, and strengthen local advocacy groups. The world watched as activists used social media to organize protests during the Arab Spring, Occupy Wall Street, and Hong Kong's Umbrella Revolution. Many governmental and community organizations changed their mission and function as they adopted new digital tools and practices. This book examines the use of “civic media”—the technologies, designs, and practices that support connection through common purpose in civic, political, and social life. Scholars from a range of disciplines and practitioners from a variety of organizations offer analyses and case studies that explore the theory and practice of civic media. The contributors set out the conceptual context for the intersection of civic and media; examine the pressure to innovate and the sustainability of innovation; explore play as a template for resistance; look at civic education; discuss media-enabled activism in communities; and consider methods and funding for civic media research. The case studies that round out each section range from a “debt resistance” movement to government service delivery ratings to the “It Gets Better” campaign aimed at combating suicide among lesbian, gay, bisexual, transgender, and queer youth. The book offers a valuable interdisciplinary dialogue on the challenges and opportunities of the increasingly influential space of civic media.

An exploration of the scientific mindset—such character virtues as curiosity, veracity, attentiveness, and humility to evidence—and its importance for science, democracy, and human flourishing. Exemplary scientists have a characteristic way of viewing the world and their work: their mindset and methods all aim at discovering truths about nature. In An Instinct for Truth , Robert Pennock explores this scientific mindset and argues that what Charles Darwin called “an instinct for truth, knowledge, and discovery” has a tacit moral structure—that it is important not only for scientific excellence and integrity but also for democracy and human flourishing. In an era of “post-truth,” the scientific drive to discover empirical truths has a special value. Taking a virtue-theoretic perspective, Pennock explores curiosity, veracity, skepticism, humility to evidence, and other scientific virtues and vices. He explains that curiosity is the most distinctive element of the scientific character, by which other norms are shaped; discusses the passionate nature of scientific attentiveness; and calls for science education not only to teach scientific findings and methods but also to nurture the scientific mindset and its core values. Drawing on historical sources as well as a sociological study of more than a thousand scientists, Pennock's philosophical account is grounded in values that scientists themselves recognize they should aspire to. Pennock argues that epistemic and ethical values are normatively interconnected, and that for science and society to flourish, we need not just a philosophy of science, but a philosophy of the scientist.
