| evac chair training video: Pedestrian and Evacuation Dynamics Richard D. Peacock, Kuligowski Erica D., Jason D. Averill, 2011-06-29 An aging population, increasing obesity and more people with mobility impairments are bringing new challenges to the management of routine and emergency people movement in many countries. These population challenges, coupled with the innovative designs being suggested for both the built environment and other commonly used structures (e.g., transportation systems) and the increasingly complex incident scenarios of fire, terrorism, and large-scale community disasters, provide even greater challenges to population management and safety. Pedestrian and Evacuation Dynamics, an edited volume, is based on the Pedestrian and Evacuation Dynamics (PED) 5th International 2010 conference, March 8th-10th 2010, located at the National Institute of Standards and Technology, Gaithersburg, MD, USA. This volume addresses both pedestrian and evacuation dynamics and associated human behavior to provide answers for policy makers, designers, and emergency management to help solve real world problems in this rapidly developing field. Data collection, analysis, and model development of people movement and behavior during nonemergency and emergency situations will be covered as well. |

| evac chair training video: City of Inmates Kelly Lytle Hernández, 2017-02-15 Los Angeles incarcerates more people than any other city in the United States, which imprisons more people than any other nation on Earth. This book explains how the City of Angels became the capital city of the world's leading incarcerator. Marshaling more than two centuries of evidence, historian Kelly Lytle Hernandez unmasks how histories of native elimination, immigrant exclusion, and black disappearance drove the rise of incarceration in Los Angeles. In this telling, which spans from the Spanish colonial era to the outbreak of the 1965 Watts Rebellion, Hernandez documents the persistent historical bond between the racial fantasies of conquest, namely its settler colonial form, and the eliminatory capacities of incarceration. But City of Inmates is also a chronicle of resilience and rebellion, documenting how targeted peoples and communities have always fought back. They busted out of jail, forced Supreme Court rulings, advanced revolution across bars and borders, and, as in the summer of 1965, set fire to the belly of the city. With these acts those who fought the rise of incarceration in Los Angeles altered the course of history in the city, the borderlands, and beyond. This book recounts how the dynamics of conquest met deep reservoirs of rebellion as Los Angeles became the City of Inmates, the nation's carceral core. It is a story that is far from over. |

| evac chair training video: Safest Place in Iraq Colonel Paul Linzey, 2020-03-10 Safest Place in Iraq tells the stories of men and women who experienced God during the war in Iraq, demonstrating the truth that Christian military chaplains are still allowed to openly share Christ and provide pastoral ministry, if they do it right. Even on good days, living for Christ is a challenging, risk-laden endeavor. One way to make the task a bit easier is to see how other Christians have successfully navigated their temptations and struggles. Safest Place in Iraq aims to do just that, by peering behind the curtain and showing how one military chaplain handled the various dangers, people, and circumstances he encountered during his war-time deployment in South Central Iraq. The result is a story that ranges from death and destruction to friendship and faith, and from temptation and torment to redemption and revival. Colonel Paul Linzey US Army Chaplain (Ret.) identifies the broad themes that everyone—both Christian and non-Christian—has to deal with when the going gets tough. He also shows by example what it takes to overcome life’s obstacles, whether dodging mortars in the desert, or fighting fear, loneliness, and temptation at home or at work. And in the process, Safest Place in Iraq shows that it is possible to remain true to one’s values and calling as a person of faith in a hostile world. |
| evac chair training video: Death on Hold Burton Folsom, Anita Folsom, 2015-08-11 In January 1983 Burt Folsom read a story in Time about Mitch Rutledge, a man on death row with an IQ of 84 who said he was sorry for what he did. Forget him, the last line of the story read. But Burt wrote Mitch a letter and discovered a man more interesting and intelligent than the article revealed. Burt and his wife, Anita, began a friendship with Mitch and saw him become a leader and role model for others in prison, teaching himself to read and write (starting with copying down the spelling of items he knew from TV commercials) and becoming a national spokesman on prison life. Death on Hold is the amazing story of their friendship, and of grace, reconciliation, and redemption for a man without hope who was given a future. |

| evac chair training video: Facing Hazards and Disasters National Research Council, Division on Earth and Life Studies, Committee on Disaster Research in the Social Sciences: Future Challenges and Opportunities, 2006-09-10 Social science research conducted since the late 1970's has contributed greatly to society's ability to mitigate and adapt to natural, technological, and willful disasters. However, as evidenced by Hurricane Katrina, the Indian Ocean tsunami, the September 11, 2001 terrorist attacks on the United States, and other recent events, hazards and disaster research and its application could be improved greatly. In particular, more studies should be pursued that compare how the characteristics of different types of events-including predictability, forewarning, magnitude, and duration of impact-affect societal vulnerability and response. This book includes more than thirty recommendations for the hazards and disaster community. |

| evac chair training video: Women Vietnam Veterans Donna A. Lowery, 2015-09-24 Women Vietnam Veterans: Our Untold Stories, by Donna Lowery, a Vietnam veteran, chronicles the participation of American military women during the Vietnam War. This little-known group of an estimated 1,000 women from the Army, Marine Corps, Navy and Air Force left its mark in Vietnam from 1962 to 1973. They served in a myriad of duties from intelligence analysts, flight controllers, clerk-typists, translators, physical therapists, dietitians and communications specialists among many others. Our Untold Stories allows the women to speak for themselves about their experiences, and, for the first time ever, brings names, facts and figures together in one literary work. The purpose of the book is to be historically significant to future researchers. The history of the military women in Vietnam began in 1962 with Army Major Anne Marie Doering. She was born in what became North Vietnam. Her father was a French officer, her mother a German citizen. When her father died, her mother married an American businessman. Her service in Vietnam as a Combat Intelligence Officer is a compelling story of the US military women in a war zone. It was not until 1965 that the US Women’s Army Corps (WAC) sent two women as advisors to assist the newly formed Vietnam Women’s Armed Forces Corps. The following year, the Army authorized the establishment of a WAC Detachment in Vietnam. Soon, thereafter, the Air Force, Marine Corps and Navy also sent women to serve in various capacities. In March 1973, under the Paris Peace Accords, the last women left Vietnam along with the remaining men. The impact they had in Vietnam set the stage for the expansion and integration of women into additional roles in the military. Today, women serve in areas of active combat, demonstrating their abilities and dedication to the mission. |
| evac chair training video: The Hunt for Zero Point Nick Cook, 2007-12-18 This riveting work of investigative reporting and history exposes classified government projects to build gravity-defying aircraft--which have an uncanny resemblance to flying saucers. The atomic bomb was not the only project to occupy government scientists in the 1940s. Antigravity technology, originally spearheaded by scientists in Nazi Germany, was another high priority, one that still may be in effect today. Now for the first time, a reporter with an unprecedented access to key sources in the intelligence and military communities reveals suppressed evidence that tells the story of a quest for a discovery that could prove as powerful as the A-bomb. The Hunt for Zero Point explores the scientific speculation that a zero point of gravity exists in the universe and can be replicated here on Earth. The pressure to be the first nation to harness gravity is immense, as it means having the ability to build military planes of unlimited speed and range, along with the most deadly weaponry the world has ever seen. The ideal shape for a gravity-defying vehicle happens to be a perfect disk, making antigravity tests a possible explanation for the numerous UFO sightings of the past 50 years. Chronicling the origins of antigravity research in the world's most advanced research facility, which was operated by the Third Reich during World War II, The Hunt for Zero Point traces U.S. involvement in the project, beginning with the recruitment of former Nazi scientists after the war. Drawn from interviews with those involved with the research and who visited labs in Europe and the United States, The Hunt for Zero Point journeys to the heart of the twentieth century's most puzzling unexplained phenomena. |
| evac chair training video: Khobar Towers: Tragedy and Response Perry D. Jamieson, 2008 This account of the Khobar Towers bombing tells the story of the horrific attack and the magnificent response of airmen doing their duty under nearly impossible circumstances. None of them view their actions as heroic, yet the reader will marvel at their calm professionalism. All of them say it was just their job, but the reader will wonder how they could be so well trained to act almost instinctively to do the right thing at the right time. None of them would see their actions as selfless, yet countless numbers refused medical attention until the more seriously injured got treatment. Throughout this book, the themes of duty, commitment, and devotion to comrades resoundingly underscore the notion that America's brightest, bravest, and best wear her uniforms in service to the nation. This book is more than heroic actions, though, for there is also controversy. Were commanders responsible for not adequately protecting their people? What should one make of the several conflicting investigations following the attack? Dr. Jamieson has not shied away from these difficult questions, and others, but has discussed them and other controversial judgments in a straightforward and dispassionate way that will bring them into focus for everyone. It is clear from this book that there is a larger issue than just the response to the bombing. It is the issue of the example set by America's airmen. Future airmen who read this book will be stronger and will stand on the shoulders of those who suffered and those who made the ultimate sacrifice. |

| evac chair training video: Learning from Megadisasters Federica Ranghieri, Mikio Ishiwatari, 2014-06-26 While not all natural disasters can be avoided, their impact on a population can be mitigated through effective planning and preparedness. These are the lessons to be learned from Japan's own megadisaster: the Great East Japan Earthquake of 2011, the fi rst disaster ever recorded that included an earthquake, a tsunami, a nuclear power plant accident, a power supply failure, and a large-scale disruption of supply chains. It is a sad fact that poor communities are often hardest hit and take the longest to recover from disaster. Disaster risk management (DRM) should therefore be taken into account as a major development challenge, and countries must shift from a tradition of response to a culture of prevention and resilience. Learning from Megadisasters: Lessons from the Great East Japan Earthquake consolidates a set of 36 Knowledge Notes, research results of a joint study undertaken by the Government of Japan and the World Bank. These notes highlight key lessons learned in seven DRM thematic clusters—structural measures; nonstructural measures; emergency response; reconstruction planning; hazard and risk information and decision making; the economics of disaster risk, risk management, and risk fi nancing; and recovery and relocation. Aimed at sharing Japanese cutting-edge knowledge with practitioners and decision makers, this book provides valuable guidance to other disaster-prone countries for mainstreaming DRM in their development policies and weathering their own natural disasters. |

| evac chair training video: Defending Air Bases in an Age of Insurgency Shannon Caudill, Air University Press, 2014-08 This anthology discusses the converging operational issues of air base defense and counterinsurgency. It explores the diverse challenges associated with defending air assets and joint personnel in a counterinsurgency environment. The authors are primarily Air Force officers from security forces, intelligence, and the office of special investigations, but works are included from a US Air Force pilot and a Canadian air force officer. The authors examine lessons from Vietnam, Iraq, Afghanistan, and other conflicts as they relate to securing air bases and sustaining air operations in a high-threat counterinsurgency environment. The essays review the capabilities, doctrine, tactics, and training needed in base defense operations and recommend ways in which to build a strong, synchronized ground defense partnership with joint and combined forces. The authors offer recommendations on the development of combat leaders with the depth of knowledge, tactical and operational skill sets, and counterinsurgency mind set necessary to be effective in the modern asymmetric battlefield. |

There’s a reason Alison Green has been called “the Dear Abby of the work world.” Ten years as a workplace-advice columnist have taught her that people avoid awkward conversations in the office because they simply don’t know what to say.

Ideal for anyone new to the job market or new to management, or anyone hoping to improve their work experience.”—Library Journal (starred review) “I am a huge fan of Alison Green’s Ask a Manager column. This book is even better. It teaches us how to deal with many of the most vexing big and little problems in our workplaces—and to do so with grace, confidence, and a sense of humor.”—Robert Sutton, Stanford professor and author of The No Asshole Rule and The Asshole Survival Guide “Ask a Manager is the ultimate playbook for navigating the traditional workforce in a diplomatic but firm way.”—Erin Lowry, author of Broke Millennial: Stop Scraping By and Get Your Financial Life Together |
