These models are constructed by three-dimensionally scanning two national- team ski jumpers taking flight postures. The drag and lift forces on each component of a ski jumper and skis (head with helmet and goggle, body, arms, legs and skis) and their lift-to-drag ratios are Keywords: obtained. For the two posture models, the drag forces on the body, legs and skis are larger than those Ski jumping on the arms and head with helmet and goggle, but the lift forces on the body and skis are larger than their Flight posture drag forces, resulting in high lift-to-drag ratios on the body and skis and low lift-to-drag ratio on the legs. -
US Barefoot History
USA BAREFOOT HISTORY Keith St Onge, World and national champion The first man reported to meet the challenge of barefoot skiing was Dick Pope Jr, on March 6, 1947. In fact, for the first time, barefooting was recorded in pictures. According to sources at Water Ski Hall of Fame and witnesses of the event, it was actually the then 17-year-old A.G. Hancock, who made the initial attempts earlier in the year, driven by pioneer Chuck Sligh in Winter Haven, Florida. Charlene Wellborn Then the first woman to ski on bare feet was Charlene Dick Pope Jr Wellborn in 1951 at Cypress Gardens. The first barefoot competition was held at the 1950 Cypress Gardens Dixie Championships. As the tournament began, the first participants ended up with nothing but headaches, until Dave Craig of Miami successfully stepped of the ski. Then Stew Mc Donald of Tampa managed a short ride without skis. Pope, unaccustomed to the rough water of the tournament area had a difficult time, but was able to move into the first place with the longest ride. Finally, a young skier from Mexico named Emilio Zamudio was up. He kicked off his ski, stood up high, and waved joyously at the crowd, winning the competition. Ken Tibado Stew Mc Donald Ken Tibado As the story goes, Ken Tibado of Lake Wales introduced the two-ski jump out in 1953 and the beach start in 1956. Barefooting’s first significant public exposure came at 1956 tournament nationals in Laport, Indiana. A young skier named Mike Osborn thrilled the crowds with one of the first major barefoot exhibition in the World. -

SELF, OTHER, AND JUMP ROPE COMMUNITY: THE TRIUMPHS OF AFRICAN AMERICAN WOMEN by WYNNETTA SCOTT-SIMMONS (Under the Direction of Ming Fang He) ABSTRACT Using Critical Race Theory, Critical Literacy, Black Feminist Thought as a theoretical framework and Oral History as research methodology, the lives of four young African American women are explored as they leave their culturally insular surroundings, “Jump Rope Communities”, to seek access to the codes of power and registers of language in all-White, all-girl, elite private schools during the late 1960’s and early 1970’s. In capturing the memories, perceptions, and lived experiences of these women over thirty years later, the journey into a world of divergences was explored--divergent language codes, divergent social, cultural, and economic stratifications, and divergent linguistic expectations, behaviors, and dispositions. -

Glenn Killinger, Service Football, and the Birth
The Pennsylvania State University The Graduate School School of Humanities WAR SEASONS: GLENN KILLINGER, SERVICE FOOTBALL, AND THE BIRTH OF THE AMERICAN HERO IN POSTWAR AMERICAN CULTURE A Dissertation in American Studies by Todd M. Mealy © 2018 Todd M. Mealy Submitted in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy May 2018 ii This dissertation of Todd M. Mealy was reviewed and approved by the following: Charles P. Kupfer Associate Professor of American Studies Dissertation Adviser Chair of Committee Simon Bronner Distinguished Professor Emeritus of American Studies and Folklore Raffy Luquis Associate Professor of Health Education, Behavioral Science and Educaiton Program Peter Kareithi Special Member, Associate Professor of Communications, The Pennsylvania State University John Haddad Professor of American Studies and Chair, American Studies Program *Signatures are on file in the Graduate School iii ABSTRACT This dissertation examines Glenn Killinger’s career as a three-sport star at Penn State. The thrills and fascinations of his athletic exploits were chronicled by the mass media beginning in 1917 through the 1920s in a way that addressed the central themes of the mythic Great American Novel. Killinger’s personal and public life matched the cultural medley that defined the nation in the first quarter of the twentieth-century. His life plays outs as if it were a Horatio Alger novel, as the anxieties over turn-of-the- century immigration and urbanization, the uncertainty of commercializing formerly amateur sports, social unrest that challenged the status quo, and the resiliency of the individual confronting challenges of World War I, sport, and social alienation. -

Evidence from Professional Ski Jumping
Nationalistic bias among international experts: Evidence from professional ski jumping Alex Krumer a,*, Felix Otto b, Tim Pawlowski b, c a Faculty of Business Administration and Social Sciences, Molde University College, Britvegen 2, Molde, 6402, Norway b University of Tübingen, Wilhelmstraße 124, DE 72074 Tübingen, Germany c Tim Pawlowski is also affiliated with the LEAD Graduate School and Research Network as well as the Interfaculty Research Institute for Sports and Physical Activity in Tuebingen. Email: [email protected]*, [email protected], [email protected] *Corresponding author This version: October 2020 Date this version was printed: 17 October 2020 Abstract: Ski jumping competitions involve subjective evaluations by judges from different countries. This may lead to nationalistic bias, according to which judges assign higher scores to their compatriots. In order to test this claim empirically, we exploit within-performance variation of scores from all World Cup, World Championship, and Olympic Games competitions between seasons 2010/11 and 2016/17. Our findings confirm that judges assign significantly higher scores to their compatriots. Further analysis reveals that the magnitude of the nationalistic bias is significantly higher in more corrupt countries, according to the Corruption Perceptions Index. Moreover, out of the 12 most observed countries in our data, only Norway and Finland had negligible estimates of the nationalistic bias both statistically and economically. However, in contrast to previous studies, we do not find that judges assign significantly different scores to jumpers whose compatriots are present on the judging panel. We discuss our findings in the context of the growing debates about the importance of replication studies and crowdsourced research. -

The primary Administration, Flight Standards purpose of thls AC is to assist pilots Service, Technical Programs Division, involved in aviation operations to 800 Independence Avenue, S.W. diagnose the potential for severe wind Washington, DC 20591. events in the vicinity of mountainous areas and to provide information on pre-flight planning techniques and in-flight evaluation strategies for avoiding destructive turbulence and loss of aircraft control. Additionally, pilots and others who must deal with weather phenomena in aviation operations also will benefit from the information contained in this AC. Pilots can review the photographs and section summaries to learn about and recognize common indicators of wind motion in the atmosphere. The photographs show physical processes and provide visual clues. The summaries cover the technical and "wonder" aspects of why certain things occur what caused it? How does it affect pre-flight and in-flight decisions? The physical aspects are covered more in-depth through the text. v Acknowledgments Thomas Q.
