This book approaches the prevention of fatal incidents in outdoor education and related fields through detailed study of past tragedies. Although safety in many fields is built on accumulated lessons from past incidents, tragedies on school or youth group camps and excursions are so infrequent and so widely scattered that knowledge from previous incidents can elude those who would benefit. Nevertheless, the emergence of unlearned lessons from the past weighs heavily when those affected by a tragedy judge whether an incident should have been prevented. This book provides a foundation for a detailed and comprehensive understanding of fatality prevention in outdoor education, and in youth camps and excursions. It compiles, examines, and analyses information on fatal incidents that have occurred over many decades, involving many kinds of groups and endeavours, from around the globe. No previous work has attempted this task.
During World War II, the air over the continental United States was a virtual third front. The little-known statistics are alarming: the Army Air Forces lost more than 4,500 aircraft in combat against Japanese army and naval air forces in the war. During the same time, the AAF lost more than 7,100 aircraft in the United States to accidents in training and transportation. Such accidents claimed the lives of more than 15,530 pilots, crewmembers and ground personnel, and the stories of their deaths are largely forgotten. This work chronicles the 6,350 known fatal AAF aircraft accidents that occurred in the continental United States from January 1941 through December 1945. Each crash summary, based on official records, provides details such as crash location and cause, the people involved and the type and number of aircraft. An aircraft serial number index, a record of AAF aircraft still listed as missing, crash statistics and a directory of AAF stations in the United States are included.
Significant changes have taken place in the policy landscape surrounding cannabis legalization, production, and use. During the past 20 years, 25 states and the District of Columbia have legalized cannabis and/or cannabidiol (a component of cannabis) for medical conditions or retail sales at the state level and 4 states have legalized both the medical and recreational use of cannabis. These landmark changes in policy have impacted cannabis use patterns and perceived levels of risk. However, despite this changing landscape, evidence regarding the short- and long-term health effects of cannabis use remains elusive. While a myriad of studies have examined cannabis use in all its various forms, often these research conclusions are not appropriately synthesized, translated for, or communicated to policy makers, health care providers, state health officials, or other stakeholders who have been charged with influencing and enacting policies, procedures, and laws related to cannabis use. Unlike other controlled substances such as alcohol or tobacco, no accepted standards for safe use or appropriate dose are available to help guide individuals as they make choices regarding the issues of if, when, where, and how to use cannabis safely and, in regard to therapeutic uses, effectively. Shifting public sentiment, conflicting and impeded scientific research, and legislative battles have fueled the debate about what, if any, harms or benefits can be attributed to the use of cannabis or its derivatives, and this lack of aggregated knowledge has broad public health implications. The Health Effects of Cannabis and Cannabinoids provides a comprehensive review of scientific evidence related to the health effects and potential therapeutic benefits of cannabis. This report provides a research agendaâ€"outlining gaps in current knowledge and opportunities for providing additional insight into these issuesâ€"that summarizes and prioritizes pressing research needs.
Vaccines have saved more lives than any other single medical advance. Yet today only four companies make vaccines, and there is a growing crisis in vaccine availability. Why has this happened? This remarkable book recounts for the first time a devastating episode in 1955 at Cutter Laboratories in Berkeley, California, thathas led many pharmaceutical companies to abandon vaccine manufacture. Drawing on interviews with public health officials, pharmaceutical company executives, attorneys, Cutter employees, and victims of the vaccine, as well as on previously unavailable archives, Dr. Paul Offit offers a full account of the Cutter disaster. He describes the nation's relief when the polio vaccine was developed by Jonas Salk in 1955, the production of the vaccine at industrial facilities such as the one operated by Cutter, and the tragedy that occurred when 200,000 people were inadvertently injected with live virulent polio virus: 70,000 became ill, 200 were permanently paralyzed, and 10 died. Dr. Offit also explores how, as a consequence of the tragedy, one jury's verdict set in motion events that eventually suppressed the production of vaccines already licensed and deterred the development of new vaccines that hold the promise of preventing other fatal diseases.
