Pre-service teachers' implicit and explicit beliefs about English language learners: An implicit association test study

Pre-service teachers' attitudes and beliefs about English Learners (ELs) are especially critical as they enter their professions among an increasingly diverse student population. This study uses an Implicit Association Test to explore implicit and explicit beliefs and attitudes of pre-service teachers about ELs. Pre-service teachers from a Southeastern U.S. university hold generally positive implicit beliefs about ELs and express positive expectations for working with ELs and school support. Implicit association test measures have potential as tools for preparing pre-service teachers and evaluating the impact of interventions that seek to improve teachers’ readiness to serve this population.     

Difference score reliabilities within the RIAS-2 and WISC-V

Many prominent intelligence tests (e.g., Wechsler Intelligence Scale for Children, Fifth Edition [WISC-V] and Reynolds Intellectual Abilities Scale, Second Edition [RIAS-2]) offer methods for computing subtest- and composite-level difference scores. This study uses data provided in the technical manual of the WISC-V and RIAS-2 to calculate reliability coefficients for difference scores. Subtest-level difference score reliabilities range from 0.59 to 0.99 for the RIAS-2 and from 0.53 to 0.87 for the WISC-V. Composite-level difference score reliabilities generally range from 0.23 to 0.95 for the RIAS-2 and from 0.36 to 0.87 for the WISC-V. Emphasis is placed on comparisons recommended by test publishers and a discussion of minimum requirements for interpretation of differences scores is provided.     

社会赞许能否调节内隐认知与外显认知的关系

自Greenwald(1995)[1]提出内隐联结测验以来,内隐认知成为社会认知研究的热点。在已往研究中,内隐认知(含内隐态度和内隐自尊)和外显认知(含外显态度和外显自尊)存在低相关,但是这个相关系数在一定范围内存在波动。本文将通过两个研究来探究这一波动背后的原因,即寻找影响两者关系的第三变量——社会赞许。研究一:探测了34名在校大学生的社会赞许倾向、内隐自尊和外显自尊。结果显示受社会赞许影响不同的人,内隐自尊和外显自尊相关系数存在数值上的高低差异,但这个差异没有达到显著效果。另外,受社会赞许影响不同的两组被试在外显自尊维度上存在显著差异。研究二:探测了45名体育大学优秀运动员对兴奋剂和普通饮料的内隐、外显态度。结果显示对服用兴奋剂和服用普通饮料这两种受社会赞许影响不同的行为,被试的内隐和外显态度的相关有细微差异,但这个差异也没有达到显著效果。另外,这两种行为态度,在外显态度的维度上存在显著差异。上述两个研究的结果显示社会赞许对内隐认知和外显认知的关系的调节作用不显著,文中讨论了这一结果产生的原因。     

Circadian rhythm effect on physical tennis performance in trained male players

To determine the effect of circadian rhythm on neuromuscular responses and kinematics related to physical tennis performance, after a standardised warm-up, 13 highly competitive male tennis players were tested twice for serve velocity/accuracy (SVA), countermovement vertical jump (CMJ), isometric handgrip strength (IS), agility T-test (AGIL) and a 10-m sprint (10-m RUN). In a randomised, counter-balance order, tennis players underwent the test battery twice, either in the morning (i.e., AM; 9:00 h) and in the afternoon (i.e., PM; 16:30 h). Paired t-tests were used to analyse differences due to time-of-day in performance variables. Comparison of morning versus afternoon testing revealed that SVA (168.5 ± 6.5 vs. 175.2 ± 6.1 km · h^?1; P = 0.003; effect size [ES] = 1.07), CMJ (32.2 ± 0.9 vs. 33.7 ± 1.1 cm; P = 0.018; ES = 1.46), AGIL (10.14 ± 0.1 vs. 9.91 ± 0.2 s; P = 0.007; ES = 1.23) and 10-m RUN time (1.74 ± 0.1 vs. 1.69 ± 0.1 s; P = 0.021; ES = 0.67) were significantly blunted during the morning testing. However, IS was not affected by time-of-day (P = 0.891). Thus, tennis performance may be reduced when competing in the morning in comparison to early evening. Therefore, coaches and tennis players should focus on schedule the SVA, power, speed and agility training sessions in the afternoon.

Automatic measurement of key ski jumping phases and temporal events with a wearable system

We propose a new method, based on inertial sensors, to automatically measure at high frequency the durations of the main phases of ski jumping (i.e. take-off release, take-off, and early flight). The kinematics of the ski jumping movement were recorded by four inertial sensors, attached to the thigh and shank of junior athletes, for 40 jumps performed during indoor conditions and 36 jumps in field conditions. An algorithm was designed to detect temporal events from the recorded signals and to estimate the duration of each phase. These durations were evaluated against a reference camera-based motion capture system and by trainers conducting video observations. The precision for the take-off release and take-off durations (indoor < 39 ms, outdoor = 27 ms) can be considered technically valid for performance assessment. The errors for early flight duration (indoor = 22 ms, outdoor = 119 ms) were comparable to the trainers' variability and should be interpreted with caution. No significant changes in the error were noted between indoor and outdoor conditions, and individual jumping technique did not influence the error of take-off release and take-off. Therefore, the proposed system can provide valuable information for performance evaluation of ski jumpers during training sessions.     

女子链球运动员冬季准备期前后的等速测试

通过对两名高水平女子链球运动员双侧的髋关节和膝关节进行等速测试,探究运动员髋关节和膝关节周围肌群的生物力学特性,为运动训练和运动康复等提供理论依据。利用等速肌力测试系统对两名运动员的髋关节和膝关节屈伸肌群以及髋关节的旋内旋外肌群进行等速测试。结果发现:两名运动员双侧髋关节和膝关节屈伸肌群以及髋关节的旋内旋外肌群的峰力矩随测试速度的增加呈递减趋势,髋膝关节峰力矩屈伸比和髋关节旋内旋外比随既定测试速度的增加呈递增趋势;同一测试速度下,伸肌肌群的峰力矩大于屈肌肌群,髋关节旋外肌群的峰力矩大于旋内肌群。

全国健美操青少年测试赛身体形态测试分析

对全国健美操联赛青少年测试赛中形态测试结果及测试出现的问题进行分析,并对运动员各身体形态指标做了描述统计和分析。结果显示:从测试赛对形态指标的评分来看,竞技健美操运动员的身材比例要求特点是四肢较长、肩宽、胸厚、腰细、髋窄。运用皮尔逊相关系数的分析计算形态、体能、技能及成套测试得分的相关性,结果显示形态指标与体能、技能、成套测试成绩均无显著相关性,甚至呈一定的负相关性。形态评分标准不符合身体形态促进各项身体素质能力的规律,测试结果不能准确反映运动员竞技能力高低,评分标准不太合理。
