Book Description
America is one killer organism away from a living nightmare that threatens all we hold dear.... A deadly cloud of powdered anthrax spores settles unnoticed over a crowded football stadium.... A school cafeteria lunch is infected with a drug-resistant strain of E. coli.... Thousands in a bustling shopping mall inhale a lethal mist of smallpox, turning each individual into a highly infectious agent of suffering and death.... Dr. Michael Osterholm knows all too well the horrifying scenarios he describes. In this eye-opening account, the nation’s leading expert on bioterrorism sounds a wake-up call to the terrifying threat of biological attack — and America’s startling lack of preparedness. He demonstrates the havoc these silent killers can wreak, exposes the startling ease with which they can be deployed, and asks probing questions about America’s ability to respond to such attacks. Are most doctors and emergency rooms able to diagnose correctly and treat anthrax, smallpox, and other potential tools in the bioterrorist’s arsenal? Is the government developing the appropriate vaccines and treatments? The answers are here in riveting detail — what America has and hasn’t done to prevent the coming bioterrorist catastrophe. Impeccably researched, grippingly told, Living Terrors presents the unsettling truth about the magnitude of the threat. And more important, it presents the ultimate insider’s prescription for change: what we must do as a nation to secure our freedom, our future, our lives.

Living Through Terror
Author: Suvendrini Perera
Publisher: Routledge
ISBN: 1317982347
Category : Social Science
Languages : en
Pages : 171
Book Description
In the era of war on terror, the term terror has tended to be applied to its sudden eruptions in the metropolises of the global north. This volume directs its attention to terror’s manifestations in other locations and lives. The title Living Through Terror refers both to the pervasiveness of terror in societies where extreme violence and war constitute the everyday processes of life as well as to the experience of surviving terror and living into the future. The contributions consider terror’s effects in those ignored and silenced locations where terror is either naturalised (the Philippines, South Africa, Timor Leste, Sri Lanka) or made invisible (the neo-liberal democracies of Australia and Italy). The stories of ruined places, displaced bodies and identities shattered and remade that emerge from these pages bring into view the socio-political systems, cultural geographies and regimes of territoriality through which terror is engendered and naturalised, and the institutions and imaginaries that continue to underpin them. The essays, literary writings and images collected here attend, in their different ways, to subjects living in and with terror as an element incorporated in their everyday, and to the processes by which terror exercises itself in their lives, whether it is perpetrated by state or non-state actors. Simultaneously, the contributions attest to the tactics subjects deploy to confront and negotiate conditions of terror, their attempts to live with and through terror and, ultimately, their strategies to recover through the everyday and the ordinary the seeds of life and hope.

Living with Terror, Working with Trauma
Author: Danielle Knafo
Publisher: Jason Aronson
ISBN: 9780765703781
Category : History
Languages : en
Pages : 622
Book Description
Terrorism and war have engendered a special set of people with distinctive and uniquely contemporary therapeutic needs. How do we cope with the personal experience of political violence? Living with Terror, Working with Trauma addresses the ways that mental health practitioners can assist survivors of terrorism. Drawing upon the experience of leading practitioners and renowned experts throughout the world, this edited volume explores the most innovative methods currently employed to help people heal--and even grow--from traumatic experiences. It argues for a multi-dimensional approach to understanding and treating the effects of terror-related trauma. Comprehensive in scope, Living with Terror, Working with Trauma covers psychodynamic, cognitive-behavioral, existential, and neuro-physiological techniques for working with individuals and groups, children and adults, both in the clinic and in the field. The contributors share their personal and clinical experiences in Hiroshima, Cambodia, the Middle East, Vietnam, and other sites of mass violence and terror, including the Holocaust. A special section is devoted to the September 11th. As it addresses the basic existential challenge of finding meaning and creatively transforming one's experience of terror and trauma, this volume explores the territory, identifies the key problems, and presents effective therapeutic solutions.

Lone Wolf Terror and the Rise of Leaderless Resistance
Author: George Michael
Publisher: Vanderbilt University Press
ISBN: 0826503373
Category : Political Science
Languages : en
Pages : 426
Book Description
On July 22, 2011, Anders Behring Breivik detonated a car bomb in downtown Oslo, Norway. He didn't stop there, traveling several hours from the city to ambush a youth camp while the rest of Norway was distracted by his earlier attack. That's where the facts end. But what motivated him? Did he have help staging the attacks? The evidence suggests a startling truth: that this was the work of one man, pursuing a mission he was convinced was just. If Breivik did indeed act alone, he wouldn't be the first. Timothy McVeigh bombed a federal building in Oklahoma City based essentially on his own motivations. Eric Robert Rudolph embarked on a campaign of terror over several years, including the Centennial Park bombing at the 1996 Olympics. Ted Kaczynski was revealed to be the Unabomber that same year. And these are only the most notable examples. As George Michael demonstrates in Lone Wolf Terror and the Rise of Leaderless Resistance, they are not isolated cases. Rather, they represent the new way warfare will be conducted in the twenty-first century. Lone Wolf Terror investigates the motivations of numerous political and ideological elements, such as right-wing individuals, ecoextremists, foreign jihadists, and even quasi-governmental entities. In all these cases, those carrying out destructive acts operate as "lone wolves" and small cells, with little or no connection to formal organizations. Ultimately, Michael suggests that leaderless resistance has become the most common tactical approach of political terrorists in the West and elsewhere.

Book Description
Infectious disease has the terrifying power to disrupt everyday life on a global scale, overwhelming public and private resources and bringing trade and transportation to a halt. In today's world, it's easier than ever to move people, animals, and materials around the planet, but the same advances that make modern infrastructure so efficient have made epidemics and even pandemics nearly inevitable. So what can -- and must -- we do in order to protect ourselves? Drawing on the latest medical science, case studies, and policy research, Deadliest enemy explores the resources and programs we need to develop if we are to keep ourselves safe from infectious disease.--

Book Description
The essays in this collection are a testimony to Milton's claim that books doe contain a potencie of life in them to be as active as that soule was whose progeny they are. They are proof that Milton's progeny, whether poetry or prose, continue to inspire readers to investigate and interpret, and that even the poet himself is at times the subject of scrutiny. Although these essays examine issues as widely diverse as the reliability of Adam's narration to Raphael and the portrayal of chaos in Paradise Lost to the poet's role as an object of erotic attention in the nineteenth century, all suggest that Milton's are still living texts.

Terrors of the Table
Author: Walter Gratzer
Publisher: OUP Oxford
ISBN: 0191578622
Category : Health & Fitness
Languages : en
Pages : 306
Book Description
Terrors of the Table is an absorbing account of the struggle to find the necessary ingredients of a healthy diet, and the fads and quackery that have always waylaid the unwary and the foolish when it comes to the matter of food and health. Walter Gratzer tells the tale of nutrition's heroes, heroines and charlatans with characteristic crispness and verve. We find an array of colourful personalities, from the distinguished but quarrelsome Liebig, to the enterprising Lydia Pinkham. But we also find the slow recognition that the lack of vital ingredients can cause terrible illnesses - scurvy, rickets, beriberi. These diseases stalked the poor in the West even into the 20th century, and scandalously remain in poorer parts of the world today. The narrative stretches from classical times to the modern day and gives a valuable historical perspective to our current understanding. It also highlights some of the problems faced by the developed world regarding health today - in particular diabetes and obesity. And despite our far greater understanding of what our body needs, there are still many who would fall for fads and fancy diets - some dangerous, others just daft. Of course, the story of nutrition does not end there. We have discovered the key vitamins and minerals our body needs, but research continues on the connections between diet, health and disease. The body's biochemistry is complex, and there are no easy answers, no magic formula, that applies to all individuals. The safest and most rational course would seem to be a sensible, moderate, and varied diet, not forgetting that 'a little of what you fancy does you good'.

Science and Technology of Terrorism and Counterterrorism, Second Edition
Author: Mark A. Prelas
Publisher: CRC Press
ISBN: 1420071823
Category : Social Science
Languages : en
Pages : 606
Book Description
Traditionally, resources on terrorism and counterterrorism tend to focus on the social, behavioral, and legal aspects of the subject, with minimal emphasis on the scientific and technological aspects. Taking into account these practical considerations, the second edition of Science and Technology of Terrorism and Counterterrorism discusses the nature of terrorism and the materials used by terrorists. It describes how intelligence professionals and law enforcement personnel can detect and destroy these materials, and how they can deal with terrorist groups. This volume begins by introducing the shift in analysis of terrorist attacks after September 11, 2001 and summarizes selected case studies. It discusses the origin and nature of terrorism and the factors involved in diplomacy. Covering a broad range of topics, the book examines: Aerosol dispersion of toxic materials Bioterrorism and the manufacture, detection, and delivery of biological agents Agricultural terrorism Nuclear terrorism and nuclear weapons systems, threats, and safeguards Chemical terrorism, including manufacture, detection, delivery, and decontamination Cyber-terrorism Personal protective equipment The role of government at federal, state, and local levels The role of international agencies and their resources, capabilities, and responsibilities The National Infrastructure Protection Plan As terrorist activities increase globally, it is critical that those charged with protecting the public understand the myriad of ways in which terrorists operate. While we cannot predict where, when, and how terrorists will strike, our vigilance in staying abreast of the terrorist threat is the only way to have a fighting chance against those who seek to destroy our world.

Arts of Living on a Damaged Planet
Author: Anna Lowenhaupt Tsing
Publisher: U of Minnesota Press
ISBN: 1452954496
Category : Science
Languages : en
Pages : 734
Book Description
Living on a damaged planet challenges who we are and where we live. This timely anthology calls on twenty eminent humanists and scientists to revitalize curiosity, observation, and transdisciplinary conversation about life on earth. As human-induced environmental change threatens multispecies livability, Arts of Living on a Damaged Planet puts forward a bold proposal: entangled histories, situated narratives, and thick descriptions offer urgent “arts of living.” Included are essays by scholars in anthropology, ecology, science studies, art, literature, and bioinformatics who posit critical and creative tools for collaborative survival in a more-than-human Anthropocene. The essays are organized around two key figures that also serve as the publication’s two openings: Ghosts, or landscapes haunted by the violences of modernity; and Monsters, or interspecies and intraspecies sociality. Ghosts and Monsters are tentacular, windy, and arboreal arts that invite readers to encounter ants, lichen, rocks, electrons, flying foxes, salmon, chestnut trees, mud volcanoes, border zones, graves, radioactive waste—in short, the wonders and terrors of an unintended epoch. Contributors: Karen Barad, U of California, Santa Cruz; Kate Brown, U of Maryland, Baltimore; Carla Freccero, U of California, Santa Cruz; Peter Funch, Aarhus U; Scott F. Gilbert, Swarthmore College; Deborah M. Gordon, Stanford U; Donna J. Haraway, U of California, Santa Cruz; Andreas Hejnol, U of Bergen, Norway; Ursula K.
