Sculptures of athletes that immortalize heroic feats have long been part of the sporting world. More recently, statues of sports fans have appeared, particularly at baseball stadiums across North America. Whilst athlete statues usually represent specific subjects, fan statues typically depict anonymous figures, giving commissioners and sculptors broader license to incorporate particular ideals. This paper investigates how the fan statuary's form reflects commissioners' motivations, values, and views of fandom, and whether fan statues promote a preferred (but often imaginary) narrative regarding the fan experience. A tripartite fan statue design typology is proposed: hero worship, family experiences, and the crowd. By examining an example of each type, with context provided by a unique database of baseball statuary, the fan statuary's predominant themes and tensions are illustrated. Fan statues are concentrated at Minor League ballparks, and all feature children. The majority are alloys of both real and imagined components of the idealized fan experience of the baseball organization's ‘ideal fan’, projecting inclusive, family-friendly, and timeless game day experiences, and evoking nostalgia for childhood. Crowd-type statues offer a more free-spirited and spontaneous aesthetic, with the crowd creating and becoming part of the spectacle – a reality that sports organizations may be less comfortable with.  相似文献

The aims of this study were to examine whether batters hit stationary balls at the time of peak speed of the bat head and whether the impact occurs at the lowest point of the bat trajectory. Eight university baseball players hit three balls, each hung with a string; each ball was made of a different material and was different in weight. Bat movement was captured by four 240-Hz infrared cameras and analysed three-dimensionally. Time for peak speed of the bat head varied according to the conditions. When stationary balls of standard weight were used, the bat head was at maximum speed at impact with the ball; then, it decelerated drastically owing to the impact. In contrast, maximum speed was obtained after impact when lightweight stationary balls were used. The time–speed profile of the bat head before impact in the lightweight ball condition was identical with that in the standard weight ball condition. Regardless of conditions, the timing of the lowest point of the bat head was nearly identical for each batter and most participants hit the stationary balls at about the lowest point of the bat trajectory  相似文献

Softballs     
There is currently much debate about the safety of the sport of softball. Batted‐ball speed and average pitcher reaction time are factors often used to determine safe performance. Batted‐ball speed is shown to be the most important factor to consider when determining safe play. Average pitcher reaction time is explained and directly correlated to batted‐ball speed. Eleven aluminum multi‐wall, three aluminum single‐wall and two composite softball bats were tested with mid‐compression polyurethane softballs averaging 1721 ±62 N/6.4 mm to represent the relative bat‐ball performance for the sport of slow‐pitch softball. Nine men and six women were chosen for this study out of a test group of over three hundred slowpitch softball players. On average, aluminum bat performance results were within the recommended safety limits established by the national softball associations. However, when composite bats were used, their performance results exceeded the recommended safety limits which can pose a significant safety risk. Using aluminum softball bats, batted‐ball speeds ranged from 80 to 145 km.h‐1. Using composite softball bats, batted‐ball speeds ranged from 146 to 161 km.h‐1. The scientific relevance of this study is to provide performance information that can lead to injury prevention in the sport of softball.  相似文献

语言是交际中的重要工具。外交中,语言的使用,话语的选择直接影响到国家形象和利益。外交发言人们首先要用认知工具理解说话人的话语含义,然后结合语境做出相应的回答或回应。本文欲从认知语用学关联理论的角度分析我国外交发言人对提问者做出的回答,认为外交对话策略可以建立在解构性对话的棒球模型之上。  相似文献
