大众冰雪运动参与休闲限制对变通策略的影响研究

通过探讨冰雪运动参与者休闲限制与变通策略的关系,分析个人、人际、结构3种限制对变通策略的影响,旨在为提高大众冰雪运动参与提供合理化路径。研究主要运用问卷调查法和数理统计法,通过回归分析发现:个人限制对变通策略有显著的负向影响,结构限制对变通策略有显著的正向影响,人际限制对变通策略影响不显著。由于个人限制对变通策略的运用具有很强抑制作用,因此提高大众冰雪运动参与最重要的途径是降低个人限制。

试析定语从句与分裂句中that属性之区别

英语定语从句和分裂句中that属性问题语言学界一直存有争议。本文通过对上述不同结构中that的结构来源、回指功能与句法约束等方面进行比较分析后得出结论为,that在定语从句中为关系词,在分裂句中为结构词。     

非典范序话语的右边界限制

SDRT只关注典范序话语,考虑到辅助先于核心的非典范序话语,右边界被重新定义：它包含最后原子节点,主导这个原子节点的任何节点和这个原子节点主导的任何节点.有了这个新定义,对于典范和非典范序话语,作为连接限制和代词前指确认限制,右边界限制有效.     

Experiential knowledge of expert coaches can help identify informational constraints on performance of dynamic interceptive actions

Abstract

Coordination of dynamic interceptive movements is predicated on cyclical relations between an individual’s actions and information sources from the performance environment. To identify dynamic informational constraints, which are interwoven with individual and task constraints, coaches’ experiential knowledge provides a complementary source to support empirical understanding of performance in sport. In this study, 15 expert coaches from 3 sports (track and field, gymnastics and cricket) participated in a semi-structured interview process to identify potential informational constraints which they perceived to regulate action during run-up performance. Expert coaches’ experiential knowledge revealed multiple information sources which may constrain performance adaptations in such locomotor pointing tasks. In addition to the locomotor pointing target, coaches’ knowledge highlighted two other key informational constraints: vertical reference points located near the locomotor pointing target and a check mark located prior to the locomotor pointing target. This study highlights opportunities for broadening the understanding of perception and action coupling processes, and the identified information sources warrant further empirical investigation as potential constraints on athletic performance. Integration of experiential knowledge of expert coaches with theoretically driven empirical knowledge represents a promising avenue to drive future applied science research and pedagogical practice.     

An improvement index to quantify the evolution of performance in running

Abstract

Improvements in track and field sports have been attributed to factors such as population increase, drugs and new technologies, but previous research has found it difficult to distinguish the contributions from specific influences. Here it is shown how this is possible by means of a performance improvement index based on useful work done combined with modelling of the annual top 25 performances. The index was set to 100 in 1948 and showed that, by 2012, it had increased in running events to between 110.5 and 146.7 (men’s 100 m and marathon). Underlying global effects accounted for the majority of all improvements (16.2 to 46.7) with smaller influences attributable to an influx of African runners (3.6 to 9.3), and a 4 -year oscillation that arose from staging of the Olympic Games (±0.2 to ±0.6). Performance decreased with the introduction of compulsory random drug testing (?0.9 to ?3.9) the World Anti-Doping Agency (WADA; ?0.5 to ?2.5) and fully automated timing (?0.6 to ?2.5). Changes in elite sporting performance since the 1890s are attributable to societal changes caused by the industrial revolution and globalisation superimposed on millennia of human evolution.
