特征性主位指的是些出现在句首、仅具有主位特性但却不能穷尽主位潜势的主位成分。章根据Halliday的系统功能语法的有关理论,从构成及其构成成分的功能意义以及结构特征等方面讨论特征性主位的有关情况,彰显其“形式是意义的体现”的语言观。  相似文献

作为第一个被引入中国,继而在不同时期形成两个“言必称奈达”现象的西方译论,奈达译论有其自身魅力。通过回顾其理论形成过程,探究在中国形成“奈达现象”的原因,进而对当前中国译者引进西方译论以及建立翻译学问题提出自己的见解。  相似文献

当前,哲学思考已开始成为教学设计的前提假设,而功能语境论是新近出现于心理学中的一种哲学观点,对教学设计具有多方面潜在贡献。通过对功能语境论的语境论世界观基础和行为分析表现形式的简要介绍,分别阐述了功能语境论对教学设计理论基础、教学设计实践取向和教学设计研究方法等方面的影响,并在此基础上进行了分析和讨论,从而明晰了功能语境论对教学设计价值取向等方面的哲学关照和反思。  相似文献

Our analysis of Anglo American, Native American, and Hispanic adolescents confirms several predictions derived from a cognitive‐functional theory of television's socialization effects. The major predictions that learning and functionality evaluations of observed values lead to acceptance were supported for each of the three ethnic groups. As the theory predicts, adolescents accepted values observed in television when they recognized them (a measure of learning) and when they evaluated the values to be important in “being successful” in the United States (a measure of functionality). Perceived realism of television and total television exposure did not predict value acceptance.  相似文献

BackgroundPostural control has been associated with the functional impairment in persons with multiple sclerosis (pwMS). However, there is a need for reliable methods to assess postural control in early stages of the disease, when subtle changes can be difficult to detect. The aims of this study were to assess the absolute and relative reliability of a standing and a sitting posturographic protocol in minimally (Expanded Disability Status Scale ≤ 2) and moderately (2.5 ≤ Expanded Disability Status Scale ≤ 4) impaired pwMS, and to analyze relationships among postural control and functional mobility and gait performance.MethodsTo assess postural control in an upright stance, 14 minimally and 16 moderately impaired pwMS performed six 70 s trials in tandem stance, 3 with their weaker leg behind (TSWL) and 3 with their stronger leg behind (TSSL). Additionally, participants completed five 70 s trials using an unstable sitting protocol (US) to assess trunk stability. The mean radial errors of TSWL, TSSL, and US trials were calculated as postural control indexes. Furthermore, participants performed the Timed Up and Go test (TUG) and the Timed 25-foot Walk test (T25FW) to measure their functional mobility and gait speed, respectively. Reliability was evaluated using the intraclass correlation coefficient (ICC3,1) and the standard error of measurement (SEM). Analyses of variances were carried out to assess between-group differences. Hedges’ g index (dg) was used to estimate the effect size of differences. Pearson correlation analyses (r) were performed to examine the relationships among the postural control and the functional tests.ResultsPosturographic tests showed a high reliability in both minimally (0.87 ≤ ICC ≤ 0.92; 9.32% ≤ SEM ≤ 11.76%) and moderately (0.80 ≤ ICC ≤ 0.92; 10.33% ≤ SEM ≤ 15.33%) impaired pwMS. Similarly, T25FW and TUG displayed a high consistency in minimally (0.89 ≤ ICC ≤ 0.94; 3.43% ≤ SEM ≤ 5.17%) and moderately (0.85 ≤ ICC ≤ 0.93; 5.57% ≤ SEM ≤ 6.56%) impaired individuals. Minimally impaired pwMS showed a better performance on the TUG, T25FW, and TSWL than moderately impaired individuals (p < 0.05; dg ≥ 0.8). The TSWL, TSSL, and US variables correlated with TUG scores (0.419 ≤ r ≤ 0.604; p < 0.05), but TSWL also correlated with T25FW scores (r = 0.53; p < 0.01). Furthermore, US scores correlated with both tandem stance parameters (TSWL: r = 0.54, p < 0.01; TSSL: r = 0.43, p < 0.05).ConclusionTandem and sitting posturographic tests provide reliable measures of postural control in pwMS, even in individuals with a homogeneous disease profile. Gait speed, functional mobility, and weaker leg status seem decisive in assessing the degree of physical activity limitation in pwMS. Finally, although trunk stability does not seem to be so affected by the course of the disease, it remains relevant for postural control and functional capacity.  相似文献

Sports injuries are common among baseball players and may result in abnormal movement patterns, increased risks of future injury, and unsatisfactory performance. The Functional Movement Screen (FMS?) has been developed to detect abnormal functional movement patterns and can be used for predicting risks of sports injury. However, whether FMS? scores are associated with athletic performance remains unclear. The goal of this study was to determine the association between functional movements and athletic performance in elite baseball players. Core stability, muscular strength and flexibility of the lower extremities, and FMS?, as well as athletic performance in sprinting, agility, and balance tests were assessed in 52 male collegiate Division I baseball players placed into two groups based on FMS? scores. The high-scoring group demonstrated better athletic performance than the low-scoring group, with a shorter duration of the agility test. No group differences were found in core stability, muscular strength, or muscle flexibility, except for rectus femoris flexibility. Thus, the FMS? score is associated with sprinting and agility performance in elite baseball players. These findings indicate that the FMS? may have a role in predicting athletic performance and thereby help determine the goals of training regimens or return-to-play strategies.  相似文献
