TRB Special Report 282: Does the Built Environment Influence Physical Activity? Examining the Evidence reviews the broad trends affecting the relationships among physical activity, health, transportation, and land use; summarizes what is known about these relationships, including the strength and magnitude of any causal connections; examines implications for policy; and recommends priorities for future research.
Includes more than 40 maps, plans and illustrations. This volume in the official History of the Marine Corps chronicles the part played by United States Marines in the Chosin Reservoir Campaign. The race to the Yalu was on. General of the Army Douglas MacArthur’s strategic triumph at Inchon and the subsequent breakout of the U.S. Eighth Army from the Pusan Perimeter and the recapture of Seoul had changed the direction of the war. Only the finishing touches needed to be done to complete the destruction of the North Korean People’s Army. Moving up the east coast was the independent X Corps, commanded by Major General Edward M. Almond, USA. The 1st Marine Division, under Major General Oliver P. Smith, was part of X Corps and had been so since the 15 September 1950 landing at Inchon. After Seoul the 1st Marine Division had reloaded into its amphibious ships and had swung around the Korean peninsula to land at Wonsan on the east coast. The landing on 26 October 1950 met no opposition; the port had been taken from the land side by the resurgent South Korean army. The date was General Smith’s 57th birthday, but he let it pass unnoticed. Two days later he ordered Colonel Homer L. Litzenberg, Jr., 47, to move his 7th Marine Regimental Combat Team north from Wonsan to Hamhung. Smith was then to prepare for an advance to the Manchurian border, 135 miles distant. And so began one of the Marine Corps’ greatest battles—or, as the Corps would call it, the “Chosin Reservoir Campaign.” The Marines called it the “Chosin” Reservoir because that is what their Japanese-based maps called it. The South Koreans, nationalistic sensibilities disturbed, preferred—and, indeed, would come to insist—that it be called the “Changjin” Reservoir.
In August 1964, thousands of Simba rebels attacked and captured the city of Stanleyville in the newly independent Republic of the Congo and took more than 1,600 European and American residents as hostages, threatening to kill them if any attempt was made to recapture the city. In November of that year, after months of increasingly tense and complex discussions among the governments whose nationals were being held, an airborne assault by Belgian paracommandos dropped by American Air Force planes, combined with a CIA-piloted air strike against the Stanleyville airport, liberated most of the hostages, but only after a Simba-initiated massacre. "Dragon Operations: Hostage Rescues in the Congo, 1964-1965" provides both the political background to these events and a detailed account of the actual operations: Dragon Rouge, the operations in Stanleyville, and Dragon Noir, focused on the city of Paulis, several hundred miles away. The book highlights the difficulties in organizing an international rescue effort with insufficient joint planning and inadequate command and control among the Belgian and American forces, as well as their differing political ideas and goals. The ad hoc nature of the planning was exemplified by an initial American Special Forces plan to air drop its forces east of Stanleyville and float down the river to Stanleyville. This plan was aborted when it was pointed out that the existence of Stanley Falls between the drop zone and the city was an insuperable obstacle. The operation also suffered from the Belgian commander's colonial-era contempt for the numerical strength of the Simbas and American fears of what was in reality a non-existent Communist element in the rebel movement."Dragon Operations" demonstrates that, despite the slapdash nature of their planning and communications aspects, as well as the distance involved, the austere support, the large number of hostages, and a lack of intelligence data, they were remarkably successful in rescuing most of the hostages. Although less than ideal, the operations worked better than expected, given the conditions under which they were conducted. This important study of an almost forgotten episode of the Cold War has much to offer to military strategists and tacticians, political scientists and students of contemporary history alike.

In the past decade, few subjects at the intersection of medicine and sports have generated as much public interest as sports-related concussions - especially among youth. Despite growing awareness of sports-related concussions and campaigns to educate athletes, coaches, physicians, and parents of young athletes about concussion recognition and management, confusion and controversy persist in many areas. Currently, diagnosis is based primarily on the symptoms reported by the individual rather than on objective diagnostic markers, and there is little empirical evidence for the optimal degree and duration of physical rest needed to promote recovery or the best timing and approach for returning to full physical activity. Sports-Related Concussions in Youth: Improving the Science, Changing the Culture reviews the science of sports-related concussions in youth from elementary school through young adulthood, as well as in military personnel and their dependents. This report recommends actions that can be taken by a range of audiences - including research funding agencies, legislatures, state and school superintendents and athletic directors, military organizations, and equipment manufacturers, as well as youth who participate in sports and their parents - to improve what is known about concussions and to reduce their occurrence. Sports-Related Concussions in Youth finds that while some studies provide useful information, much remains unknown about the extent of concussions in youth; how to diagnose, manage, and prevent concussions; and the short- and long-term consequences of concussions as well as repetitive head impacts that do not result in concussion symptoms. The culture of sports negatively influences athletes' self-reporting of concussion symptoms and their adherence to return-to-play guidance. Athletes, their teammates, and, in some cases, coaches and parents may not fully appreciate the health threats posed by concussions. Similarly, military recruits are immersed in a culture that includes devotion to duty and service before self, and the critical nature of concussions may often go unheeded. According to Sports-Related Concussions in Youth, if the youth sports community can adopt the belief that concussions are serious injuries and emphasize care for players with concussions until they are fully recovered, then the culture in which these athletes perform and compete will become much safer. Improving understanding of the extent, causes, effects, and prevention of sports-related concussions is vitally important for the health and well-being of youth athletes. The findings and recommendations in this report set a direction for research to reach this goal.
"Scouring the history of Native American boarding schools, nineteenth-century reformatories, and programs to Americanize immigrants, Glenn brilliantly reveals the role of coercion in caregiving. An important read for us all."---Arlie Hochschild, author of The Time Bind --
