错位与救赎:晚清小说的慕史观念     

贺根民 《华侨大学学报(哲学社会科学版)》2006,1(4):103-108

小说的慕史观念,是一种无奈的追寻,它既是小说作茧自缚的文学理念,又是其冲出围城的希望。尴尬的社会身份和错位的批评心态,长期滞阻了小说理论的正常发展。异域文化的移植,给近代小说指明了一条崭新的发展途径,回归于对普通人生的体察。小说立足于世俗人情的维度,突破慕史的既定途辙,把捉寻常家庭的生活场景,获就文体独立的存在价值。  相似文献   

网络诗歌与传统诗歌审美错位研究     

张翠 《襄阳职业技术学院学报》2021,(1):127-131

作为诗歌新形式,网络诗歌的内在诗性也发生了一定变化,其审美取向与传统诗歌审美偏好出现错位与偏离.网络诗歌审美表现出的拒绝抒情传统、削平诗意表达深度、异化诗歌传统功能等新表征导致网络诗歌与传统诗歌审美之间出现抒情错位、表达错位和功能错位等现象.促使错位弥合的构想之一是大力倡导网络现代禅诗的创作与研究,这不仅有助于规范网络...  相似文献

The effects of localised fatigue on upper extremity jump shot kinematics and kinetics in team handball     

Hillary A. Plummer 《Journal of sports sciences》2017,35(2):182-188

Team handball is a popular sport worldwide that requires numerous throws to be made throughout the course of a game. Because of the upper extremity demands of repetitive throwing, it is possible that fatigue can alter the mechanics of a shot. The purpose of this study was to determine the influence of localised fatigue on jump shot kinematics and kinetics. Eleven male team handball players (23.1 ± 3.1 years; 185.1 ± 8.3 cm; 89.7 ± 12.2 kg) volunteered. An electromagnetic tracking system was used to examine the jump shot prior to and following localised fatigue. The fatiguing protocol consisted of throwing a 2.2 kg medicine ball into a rebounder until volitional fatigue. No significant kinematic or kinetic differences were observed following fatigue. Shoulder external rotation was ?74.8 ± 14.9° prior to and ?79.0 ± 14.7° following fatigue at MER. Scapula, external rotation at ball release (BR) prior to fatigue was ?2.2 ± 7.0° and ?3.2 ± 11.1° following fatigue. Scapular internal rotation, at maximum shoulder internal rotation (MIR), changed from 18.4 ± 11.2° to 20.4 ± 11.8°. Ball velocity decreased from19.8 m · s^–1 to 18.8 m · s^–1 (P = 0.12). Accuracy percentage in the pre-fatigue trials was 60.8 ± 14.1% and 52.8 ± 12.7% following fatigue (P = 0.20). While no significant changes were observed, it is possible that other fatiguing protocols that more closely represent the aerobic and throwing demands of the sport may have a greater effect on the kinematics and kinetics of the jump shot.  相似文献

Upper limb joint muscle/tendon injury and anthropometric adaptations in French competitive tennis players     

Isabelle Rogowski  Thomas Creveaux  Cyril Genevois  Shahnaz Klouche  Michel Rahme  Philippe Hardy 《European Journal of Sport Science》2016,16(4):483-489

The purpose of this study was to examine the relationship between the upper limb anthropometric dimensions and a history of dominant upper limb injury in tennis players. Dominant and non-dominant wrist, forearm, elbow and arm circumferences, along with a history of dominant upper limb injuries, were assessed in 147 male and female players, assigned to four groups based on location of injury: wrist (n = 9), elbow (n = 25), shoulder (n = 14) and healthy players (n = 99). From anthropometric dimensions, bilateral differences in circumferences and in proportions were calculated. The wrist group presented a significant bilateral difference in arm circumference, and asymmetrical bilateral proportions between wrist and forearm, as well as between elbow and arm, compared to the healthy group (6.6 ± 3.1% vs. 4.9 ± 4.0%, P < 0.01; ?3.6 ± 3.0% vs. ?0.9 ± 2.9%, P < 0.05; and ?2.2 ± 2.2% vs. 0.1 ± 3.4%, P < 0.05, respectively). The elbow group displayed asymmetrical bilateral proportions between forearm and arm compared to the healthy group (?0.4 ± 4.3% vs. 1.5 ± 4.0%, P < 0.01). The shoulder group showed significant bilateral difference in elbow circumference, and asymmetrical bilateral proportions between forearm and elbow when compared to the healthy group (5.8 ± 4.7% vs. 3.1 ± 4.8%, P < 0.05 and ?1.7 ± 4.5% vs. 1.4 ± 4.3%, P < 0.01, respectively). These findings suggest that players with a history of injury at the upper limb joint present altered dominant upper limb proportions in comparison with the non-dominant side, and such asymmetrical proportions would appear to be specific to the location of injury. Further studies are needed to confirm the link between location of tennis injury and asymmetry in upper limb proportions using high-tech measurements in symptomatic tennis players.  相似文献   

Differences among fastball,curveball, and change-up pitching biomechanics across various levels of baseball     

Glenn S. Fleisig  Walter A. Laughlin  Kyle T. Aune  E. Lyle Cain  Jeffrey R. Dugas  James R. Andrews 《Sports biomechanics / International Society of Biomechanics in Sports》2016,15(2):128-138

Controversy continues whether curveballs are stressful for young baseball pitchers. Furthermore, it is unproven whether professional baseball pitchers have fewer kinematic differences between fastballs and off-speed pitches than lower level pitchers. Kinematic and kinetic data were measured for 111 healthy baseball pitchers (26 youth, 21 high school, 20 collegiate, 26 minor league, and 18 major league level) throwing fastballs, curveballs, and change-ups in an indoor biomechanics laboratory with a high-speed, automated digitising system. Differences between pitch types and between competition levels were analysed with repeated measures ANOVA. Shoulder and elbow kinetics were greater in fastballs than in change-ups, while curveball kinetics were not different from the other two types of pitches. Kinematic angles at the instant of ball release varied between pitch types, while kinematic angles at the instant of lead foot contact varied between competition levels. There were no significant interactions between pitch type and competition level, meaning that kinetic and kinematic differences between pitch types did not vary by competition level. Like previous investigations, this study did not support the theory that curveballs are relatively more stressful for young pitchers. Although pitchers desire consistent kinematics, there were differences between pitch types, independent of competition level.  相似文献

The interplay between resentment,motivation, and performance     

Myisha Cherry 《体育哲学杂志》2019,46(2):147-161

ABSTRACT

While anger in sports has been explored in philosophy, the phenomenon known as having a ‘chipped shoulder’ (or CSP) has not. In this paper I explore the nature, causes, and effects of playing with a ‘chip on your shoulder’ in order to highlight the interplay between resentment, motivation, and performance. CSP, on my account, involves a lasting grudge, controlled anger, and desire for non-moral payback at being overlooked, slighted, or underestimated in sports presently or at one point in one’s career. I argue that CSP can motivate and thus enhance athletic performance. I also show how athletes can and should have a chipped shoulder forever.  相似文献
