Drawing from social identity theory and its categorization process, the present study crossexamines Japanese students’ contrastively
different attitudes toward Asians and European (-looking) people in two different contexts: (1) Japanese students in the overseas
English language school context who perceive a sense of solidarity with other Asian, particularly Korean, students in the
presence of European students and (2) Japanese students’ yearning for ‘white English’ speakers in Japan and their disregard
for Asian and African-looking students on campus. Based on primary data and literature knowledge base, the present study argues
that Japanese students’ inclination to make friends with other Asian friends in English speaking countries is context-bound
and once they return to their less multicultural home country, their intact yearning for the Imagined West is rekindled. Further
discussions are provided for those involved in international education and foreign language education as well as English-as-a-world-language
education in postsecondary education. 相似文献

This study examined the influence of three personal factors, namely, prior knowledge about the text topic, external strategy use during reading, and experience in college, on students' comprehension of the relations among controversial texts. Eighty-six 1-year and 80 3-year undergraduate students answered a questionnaire assessing topic knowledge. One week later, they read two controversial texts and then completed two tasks assessing their comprehension of intertextual relations and recall of intratextual arguments respectively. The results indicated that topic knowledge influenced the comprehension of intertextual relations through enhancing the processing of intratextual arguments. The production of summary notes during reading had indirect and direct positive effects. Longer experience in college led to a better understanding of intertextual relations. 相似文献

Validity and reliability of body composition assessed by the sulphur hexafluoride dilution method 总被引：1，自引：0，他引：1
The aims of this study were to assess the validity and reliability of body volume and percent body fat determined by sulphur hexafluoride dilution, using underwater weighing as the criterion method, and to determine the influence of the magnitude of body volume. Thirty-one healthy Japanese individuals aged 18-27 years (16 males: height 1.70 +/- 0.06 m, mass 64.8 +/- 7.7 kg; 15 females: height 1.60 +/- 0.05 m, mass 55.2 +/- 6.2 kg; mean +/- s) participated in the study. Sulphur hexafluoride dilution measures the concentration of sulphur hexafluoride gas in the chamber (BSF-200, Shimazu Corp.). Underwater weighing was performed five times using a weight scale (AD-6204, A&D) after residual volume had been determined (System9, Minato Medical Corp.). There were no significant differences in the mean between two trials for body volume, body density or percent body fat determined by sulphur hexafluoride dilution. The intra-class correlation coefficient of these variables ranged from 0.985 to 0.999. The results suggest that sulphur hexafluoride dilution is a reliable method for assessing body composition. There was no significant difference in body volume or percent body fat between sulphur hexafluoride dilution (males: 61.3 +/- 7.6 litres, 18.4 +/- 6.7%; females: 52.8 +/- 6.9 litres, 21.0 +/- 8.9%) and underwater weighing (males: 60.6 +/- 7.0 litres, 15.6 +/- 3.5%; females: 53.0 +/- 6.5 litres, 23.7 +/- 6.1%) and there was a high correlation between the two (r = 0.997, P < 0.05). A Bland-Altman plot of the difference between percent body fat estimated by underwater weighing and sulphur hexafluoride dilution versus average percent body fat by the two methods showed no systematic difference (mean difference = -0.12 +/- 6.6 kg). The upper and lower limits of agreement were 13.2% and -13.4%, respectively. Determination by sulphur hexafluoride dilution resulted in both over- and underestimations in body volume and the difference between the two body volumes (determined by underwater weighing and by sulphur hexafluoride dilution) was inversely proportional to the mean body volume by the two methods. This suggests that improvements need to be made to the device or to the technique to maintain a constant volume of sulphur hexafluoride in the chamber. 相似文献

The purpose of this study was to investigate joint kinetics of the throwing arms and role of trunk motion in skilled elementary school boys during an overarm distance throw. Throwing motions of 42 boys from second, fourth, and sixth grade were videotaped with three high-speed cameras operating at 300 fps. Seven skilled boys from each grade were selected on the basis of throwing distance for three-dimensional kinetic analysis. Joint forces, torques, and torque powers of the throwing arm joints were calculated from reconstructed three-dimensional coordinate data smoothed at cut-off frequencies of 10.5–15 Hz and by the inverse dynamics method. Throwing distance and ball velocity significantly increased with school grade. The angular velocity of elbow extension before ball release increased with school grade, although no significant increase between the grades was observed in peak extension torque of elbow joint. The joint torque power of shoulder internal/external rotation tended to increase with school grade. When teaching the overarm throw, elementary school teachers should observe large backward twisting of trunk during the striding phase and should keep in mind that young children, such as second graders (age 8 years), will be unable to effectively utilise shoulder external/internal rotation during the throwing phase. 相似文献

清真慢词的网状框架及其解读 总被引：1，自引：0，他引：1
小林春代 《天津师范大学学报(社会科学版)》2001,(6):67-71
周邦彦的慢词框架呈网状。每片是一组网块，皆有一纲数目；全词又有统帅各网块的总纲。此种框架富有立体感、流动感，充满活力。它不同于复杂结构。复式是由线到面的平面结构；网状由纲、目构筑框架，是立体结构。分析复式结构宜用线索解读法，审察网状框架应试用网状解读法。前者依赖线索，后者依赖纲目，虽不丢弃线索，但对它绝非依赖，而是立于框架之颠，居高临下地俯瞰线索。 相似文献

Originating from a large-scale questionnaire-based study on Japanese high school students' attitudes towards current and long-term English learning, this study attempts to account for one of the findings, female students' superiority in attitudes to English learning over male students. This study problematises the common practice found in questionnaire-based research ending with the statistical identification of gender differences in attitudes without exploring factors influencing those differences. By utilising multidisciplinary extant data and research findings, this study argues that Japanese social elements, such as the status of English as feminised academic and professional choices and women's marginalised status in Japanese mainstream society, underlie many women's positive attitudes towards English learning. This study provides pedagogical implications for those in charge of English-related programmes either in Japan or in English-speaking countries who deal with a significant number of young Japanese female students in the programmes. 相似文献

This study evaluated baseball pitching accuracy using a variety of parameters to quantify pitching errors and analysed the validity of the accuracy measurements by comparing the outcomes of two small groups of pitchers. Several professional (n = 5) and high school (n = 8) pitchers threw 30 pitches each, including 20 fastballs and 10 breaking balls. To assess pitching accuracy, pitch locations relative to the catcher’s mitt (as the target) were evaluated with various parameters, including major/minor radius, an area of 95% confidence ellipse, absolute error, constant error and pitch location trajectory. Compared to the high school pitchers, the professional pitchers exhibited shorter major and minor radii in their 20 fastball pitches (p < 0.05), more accurate control in the lateral direction (p < 0.05), and shorter pitch location trajectories (p < 0.05). The evaluation methods presented in this study can objectively assess pitching accuracy and may thus provide useful coaching feedback with visual information. 相似文献

This paper describes the use of Pareto-optimal solutions for the screw kick in rugby. We attempted to optimise the initial
conditions for a screw kick. The optimisation was carried out using an elitist non-dominated sorting genetic algorithm. Distance
achieved in flight is considered as an objective function, as well as the lateral deviation between the ball and the touchline,
or the flight time. Six initial conditions were defined as control parameters: the magnitude of the velocity vector, the flight
path angle, the azimuth angle, the spin rate, the pitch angle and the yaw angle. The results are summarised as follows: it
is impossible for both objective functions to be satisfied simultaneously, although the greatest distance achieved in flight
and the smallest value of the lateral deviation between the ball and the touchline, or the least flight time, is the ideal
situation. This kind of conflicting solution is called a ‘Pareto-optimal solution’. The optimal kick in Pareto-optimal solutions
made by the leg nearest the touchline produces a greater flight distance than the optimal kick in Pareto-optimal solutions
made using the leg furthest from the touchline. The initial pitch angle, which is the angle between the longitudinal axis
of the ball and the horizontal plane, should be comparable to or slightly greater than the initial flight path angle in order
to satisfy the Pareto-optimal solutions. 相似文献
