Book excerpt: The term "peer-to-peer" has come to be applied to networks that expect end users to contribute their own files, computing time, or other resources to some shared project. Even more interesting than the systems' technical underpinnings are their socially disruptive potential: in various ways they return content, choice, and control to ordinary users. While this book is mostly about the technical promise of peer-to-peer, we also talk about its exciting social promise. Communities have been forming on the Internet for a long time, but they have been limited by the flat interactive qualities of email and Network newsgroups. People can exchange recommendations and ideas over these media, but have great difficulty commenting on each other's postings, structuring information, performing searches, or creating summaries. If tools provided ways to organize information intelligently, and if each person could serve up his or her own data and retrieve others' data, the possibilities for collaboration would take off. Peer-to-peer technologies along with metadata could enhance almost any group of people who share an interest--technical, cultural, political, medical, you name it. This book presents the goals that drive the developers of the best-known peer-to-peer systems, the problems they've faced, and the technical solutions they've found. Learn here the essentials of peer-to-peer from leaders of the field: Nelson Minar and Marc Hedlund of target="new">Popular Power, on a history of peer-to-peer Clay Shirky of acceleratorgroup, on where peer-to-peer is likely to be headed Tim O'Reilly of O'Reilly & Associates, on redefining the public's perceptions Dan Bricklin, cocreator of Visicalc, on harvesting information from end-users David Anderson of SETI@home, on how SETI@Home created the world's largest computer Jeremie Miller of Jabber, on the Internet as a collection of conversations Gene Kan of Gnutella and GoneSilent.com, on lessons from Gnutella for peer-to-peer technologies Adam Langley of Freenet, on Freenet's present and upcoming architecture Alan Brown of Red Rover, on a deliberately low-tech content distribution system Marc Waldman, Lorrie Cranor, and Avi Rubin of AT&T Labs, on the Publius project and trust in distributed systems Roger Dingledine, Michael J.

Available in PDF, EPUB and Kindle. Book excerpt: Argues that ordinary people exercise extraordinary political courage and power in American politics when, frustrated by politics as usual, they rise up in anger and hope, and defy the authorities and the status quo rules that ordinarily govern their daily lives. By doing so, they disrupt the workings of important institutions and become a force in American politics. Drawing on critical episodes in U.S. history, Piven shows that it is in fact precisely at those seismic moments when people act outside of political norms that they become empowered to their full democratic potential.

Book excerpt: Thinkers50 Management Thinker of 2015 Whitney Johnson wants you to consider this simple, yet powerful, idea: disruptive companies and ideas upend markets by doing something truly different--they see a need, an empty space waiting to be filled, and they dare to create something for which a market may not yet exist. As president and cofounder of Rose Park Advisors' Disruptive Innovation Fund with Clayton Christensen, Johnson used the theory of disruptive innovation to invest in publicly traded stocks and private early-stage companies. In Disrupt Yourself, she helps you understand how the frameworks of disruptive innovation can apply to your particular path, whether you are: a self-starter ready to make a disruptive pivot in your business a high-potential individual charting your career trajectory a manager looking to instill innovative thinking amongst your team a leader facing industry changes that make for an uncertain future We are living in an era of accelerating disruption; no one is immune. Johnson makes the compelling case that managing the S-curve waves of learning and mastery is a requisite skill for the future. If you want to be successful in unexpected ways, follow your own disruptive path. Dare to innovate. Do something astonishing. Disrupt yourself.

Available in PDF, EPUB and Kindle. Book excerpt: The histories of the Dirty Wars in Mexico and Argentina (1960s–1980s) have largely erased how women experienced and remember the gendered violence during this traumatic time. Viviana Beatriz MacManus restores women to the revolutionary struggle at the heart of the era by rejecting both state projects and the leftist accounts focused on men. Using a compelling archival blend of oral histories, interviews, human rights reports, literature, and film, MacManus illuminates complex narratives of loss, violence, and trauma. The accounts upend dominant histories by creating a feminist-centered body of knowledge that challenges the twinned legacies of oblivion for the victims and state-sanctioned immunity for the perpetrators. A new Latin American feminist theory of justice emerges—one that acknowledges women's strength, resistance, and survival during and after a horrific time in their nations' histories. Haunting and methodologically innovative, Disruptive Archives attests to the power of women's storytelling and memory in the struggle to reclaim history.

This book was released on 2020 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: In October 2019, Abhijit Banerjee, Esther Duflo, and Michael Kremer jointly won the 51st Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for their experimental approach to alleviating global poverty. But what is the exact scope of their experimental method, known as randomized control trials (RCTs)? Which sorts of questions are RCTs able to address and which do they fail to answer? The first of its kind, Randomized Control Trials in the Field of Development: A Critical Perspective provides answers to these questions, explaining how RCTs work, what they can achieve, why they sometimes fail, how they can be improved and why other methods are both useful and necessary. Bringing together leading specialists in the field from a range of backgrounds and disciplines (economics, econometrics, mathematics, statistics, political economy, socioeconomics, anthropology, philosophy, global health, epidemiology, and medicine), it presents a full and coherent picture of the main strengths and weaknesses of RCTs in the field of development. Looking beyond the epistemological, political, and ethical differences underlying many of the disagreements surrounding RCTs, it explores the implementation of RCTs on the ground, outside of their ideal theoretical conditions and reveals some unsuspected uses and effects, their disruptive potential, but also their political uses. The contributions uncover the implicit worldview that many RCTs draw on and disseminate, and probe the gap between the method's narrow scope and its success, while also proposing improvements and alternatives. Without disputing the contribution of RCTs to scientific knowledge, Randomized Control Trials in the Field of Development warns against the potential dangers of their excessive use, arguing that the best use for RCTs is not necessarily that which immediately springs to mind. Written in plain language, this book offers experts and laypeople alike a unique opportunity to come to an informed and reasoned judgement on RCTs and what they can bring to development.

Available in PDF, EPUB and Kindle. Book excerpt: In a time when organisations simultaneously run multiple corporate initiatives and large change programmes, Disruptive Ideas tells us that - contrary to the collective mindset that says that big problems need big solutions - all you need is a small set of powerful rules to create big impact. In his previous book, Viral ChangeTM, Leandro Herrero described how a small set of behaviours, spread by a small number of people could create sustainable change. In this follow-up book, the author suggests a menu of 10 'structures', 10 'processes' and 10 'behaviours' that have the power to transform an organisation. These 30 disruptive ideas can be implemented at any time and at almost no cost; and what's more...you don't even need them all. But their compound effect - the 10+10+10 maths - will be more powerful than vast corporate programmes with dozens of objectives and efficiency targets... This book will appeal to people at different levels of management or leadership, who want to reshape their culture by enhancing working practices and in general aiming at greater organisational effectiveness. Its practical nature will appeal to all who want to implement key ideas that have the power to transform any organisation, without having to embark upon a massive change management programme.

Book excerpt: Disruptive Play: The Trickster in Politics and Culture journeys from ancient folkloric appearances of Tricksters such as Raven and ṣ -Elegba, to their confined role in Western civilization, and then on to Trickster's 20th century jailbreak as led by dada and the hippies. Disruptive Play bears witness to how this spirit informs social progress today, whether by Anonymous, Banksy, Bugs Bunny, or unrevealed mischief-makers and culture jammers. Such play is revolutionary and lights the path to a transformed society. Original Play is the frolic and noncompetitive play that animals and human babies do in order to have fun and to keep on playing...not to win or to lose. It is a substance of the universe that occurs in all life. It is the behavior by which love and belonging are expressed, given, and received. When play moves into contest or other roles and rules, with winners and losers, it becomes Cultural Play. Issues of ego and narcissism are issues for Cultural Play, not for Original Play. Disruptive Play occurs in the rare times when the rhythms of Original Play suddenly appear in a political or cultural setting, settings conventionally fraught with Cultural Play. Like driving a clown car across the field during an official NFL game. Or Raven tricking Chief into releasing the sun, the moon, and the stars into the sky. Or a surreptitious Banksy graffiti that invades a museum or the public commons. Tricking power into performing an act of love. Disruptive Play: The Trickster In Politics and Culture connects knowledge from mythology, folklore, popular culture, art, politics, and play theory to make its casethatto be playful means not taking power seriously. At critical mass, power collapses and leaves us swimming about in the waters of the amoral Trickster.New values emerge and could lead to some version of the dystopia that currently drenches popular culture. Or, if people can discern between the authentic contact and exhilaration of play, and branded, mediated, alienated pleasure, then we just might stumble and frolic our way to the Play Society. Disurptive Play is ideal for enthusiasts of the human condition and those who hold out for the vision, however slim, of the Play Society.

Book excerpt: Many people need help planning for retirement, saving, investing, and decumulating their assets, yet financial advice is often complex, potentially conflicted, and expensive. The advent of computerized financial advice offers huge promise to make accessible a more coherent approach to financial management, one that takes into account not only clients' financial assets but also human capital, home values, and retirement pensions. Robo-advisors, or automated on-line services that use computer algorithms to provide financial advice and manage customers' investment portfolios, have the potential to transform retirement systems and peoples' approach to retirement planning. This volume offers cutting-edge research and recommendations regarding the impact of financial technology, or FinTech, to disrupt retirement planning and retirement system design.

Available in PDF, EPUB and Kindle. Book excerpt: In New York City in 2009, a new kind of public school opened its doors to its inaugural class of middle schoolers. Conceived by a team of game designers and progressive educational reformers and backed by prominent philanthropic foundations, it promised to reinvent the classroom for the digital age. Ethnographer Christo Sims documented the life of the school from its planning stages to the graduation of its first eighth-grade class. Disruptive Fixation is his account of how this "school for digital kids," heralded as a model of tech-driven educational reform, reverted to a more conventional type of schooling with rote learning, an emphasis on discipline, and traditional hierarchies of authority. Troubling gender and racialized class divisions also emerged. Sims shows how the philanthropic possibilities of new media technologies are repeatedly idealized even though actual interventions routinely fall short of the desired outcomes—often dramatically so. He traces the complex processes by which idealistic tech-reform perennially takes root, unsettles the worlds into which it intervenes, and eventually stabilizes in ways that remake and extend many of the social predicaments reformers hope to fix. Sims offers a nuanced look at the roles that powerful elites, experts, the media, and the intended beneficiaries of reform—in this case, the students and their parents—play in perpetuating the cycle. Disruptive Fixation offers a timely examination of techno-philanthropism and the yearnings and dilemmas it seeks to address, revealing what failed interventions do manage to accomplish—and for whom.

It specifically discusses the four main trends that will shape tomorrow's world: - Demographics-by 2040, 1.4 billion people will be added mostly in Africa and South Asia. - Economics-increased government debt and concentrated economic power will escalate problems for the poor and middleclass. - Climate-a hotter world will increase water, food, and health insecurity. - Technology-the emergence of new technologies could both solve and cause problems for human life. Students of trends, policymakers, entrepreneurs, academics, journalists and anyone eager for a glimpse into the next decades, will find this report, with colored graphs, essential reading.

Book excerpt: There is a craft to uprising -- and this craft can change the world From protests around climate change and immigrant rights, to Occupy, the Arab Spring, and #BlackLivesMatter, a new generation is unleashing strategic nonviolent action to shape public debate and force political change. When mass movements erupt onto our television screens, the media consistently portrays them as being spontaneous and unpredictable. Yet, in this book, Mark and Paul Engler look at the hidden art behind such outbursts of protest, examining core principles that have been used to spark and guide moments of transformative unrest. With incisive insights from contemporary activists, as well as fresh revelations about the work of groundbreaking figures such as Gandhi, Martin Luther King Jr., Gene Sharp, and Frances Fox Piven, the Englers show how people with few resources and little conventional influence are engineering the upheavals that are reshaping contemporary politics. Nonviolence is usually seen simply as a philosophy or moral code. This Is an Uprising shows how it can instead be deployed as a method of political conflict, disruption, and escalation. It argues that if we are always taken by surprise by dramatic outbreaks of revolt, we pass up the chance to truly understand how social transformation happens.

Book excerpt: Your invitation to move beyond pity, helplessness, and outrage, and your playbook for making a difference right where you are. As the daily newsfeed full of suffering and injustice scrolls by, it's all too easy to question what one person can really do to enact the profound change the world needs. Like moviegoers, we often watch and witness with care, but assume the script has already been written. Disruptive Compassion dares to make a bold counter: you possess the power to provoke real and meaningful change. Why? Because God has empowered you to rewrite the story of tomorrow. Over 2,000 years ago, Jesus created a model for revolutionaries that has been followed ever since. These principles are just as powerful to guide our journey today. With raw and inspiring stories from the world's most desperate places and his own journey to find meaning, Convoy of Hope founder and CEO Hal Donaldson will take you on a tour along the frontlines of courage and compassion. Let this book be your crash course in what it means to become a revolutionary, as you learn how to: Evaluate the resources you already have Navigate real concerns and risks Check your motives And ultimately become equipped as an agitator with purpose With principles and insights gleaned from two decades of relief work, Hal reveals what he's learned from the journey and what we can take with us as we join the revolution.
