Abstract This paper discusses the political and theoretical implications of the various performances of queer self‐naming (or the refusal of which) in the face of the ongoing backlash against unconventional or non‐normative genders and sexualities. It argues that, instead of a hasty call for the discarding of identity terms or naïve recourse to them, we could keep (re)using the signs without endorsing their normative meanings and line of demarcation. Through analysing some of the feminist counter‐discourses against the backlash, arguments for indigenous Japanese queerness, and a performance by a Japanese lesbian artist, Ito Tari, it shows that the queer gesture of equivocally assuming the scandalous ‘name’ may be one of the few effective survival strategies for those who have already been scandalously (mis)named. 相似文献

Social contexts shape the development of attention; however, little is known about joint attention beyond infancy. This study employed behavioral and eye-tracking measurements to investigate cultural variations in how caregivers direct 3- to 4-year-old children's attention and subsequent changes in children's attention to objects and contextual backgrounds in the United States (predominantly non-Hispanic Whites) and Japan (N = 60 mother-child dyads, 29 girls, 31 boys). The findings revealed that caregivers directed children's attention to culturally sensitive information, and significant cross-cultural differences in attention emerged after caregiver–child interaction, with Japanese children shifting their attention to the backgrounds. Results provide new insights into the role of social interaction and cultural diversity in the development of attention. 相似文献

The aim of the present study was to examine elbow joint extension power-load characteristics with and without a countermovement. Eight male participants performed maximal elbow extensions with and without a countermovement against different loads (0, 2.5, 5.0, 7.5, 10.0, 12.5, and 15.0 kg). Electromyographic activity of the lateral and long heads of the triceps brachii and the biceps brachii muscles was recorded. The average joint power in the concentric phase was significantly enhanced in the countermovement condition at all loads except for 0 kg. The optimal load for the maximal joint power was greater in the countermovement (7.5 kg) than in the no countermovement condition (5.0 kg). Electromyographic activity was unchanged over the intensities and conditions. Our results suggest that the optimal load for the maximal joint power depends on the type of action (i.e. with or without a counter-movement), and that the enhanced joint power in the countermovement condition is due primarily to the storage and utilization of elastic energy. 相似文献

近30年以来,日本、韩国和中国先后走上了相似的教育改革道路。本文通过对比三国的有关指导文件和教科书,对义务教育阶段世界地理教育的现状进行反思。一方面了解三国正在进行的教育课程改革中世界地理教育可能存在的问题,另一方面,试图以日本和韩国的经验与教训,为正在课程改革的道路上急行的中国提供有益的借鉴。 相似文献

The aim of the present study was to examine the effects of viscoelastic properties of human tendon structures during stretch?–?shortening cycle exercise. The elongation of tendon and aponeurosis of the medial gastrocnemius muscle of 26 participants was measured by ultrasonography while they performed ramp isometric plantar flexion up to the voluntary maximum, followed by a ramp relaxation. The relationship between estimated muscle force and tendon elongation during the ascending phase was fitted to a linear regression, the slope of which was defined as stiffness. The percentage of the area within the muscle force?–?tendon elongation loop relative to the area beneath the curve during the ascending phase was defined as hysteresis. In addition, maximal voluntary concentric contractions at 2.09 and 3.14 rad?·?s?1 with and without prior eccentric contractions were performed. The difference in the concentric torque at equivalent joint angles with and without prior eccentric contractions (i.e. pre-stretch augmentation) was negatively correlated with stiffness (P <?0.05) and hysteresis (P <?0.05). Furthermore, there was a higher correlation between the pre-stretch augmentation and the viscoelastic properties index – that is, the sum of normalized score values of stiffness and hysteresis (P <?0.01) – than with either stiffness or hysteresis alone. The results of this study suggest that performance during stretch?–?shortening cycle exercise is significantly affected by the viscoelastic properties of the tendon structures. 相似文献

The purpose of this paper is to sketch thecontexts, nature and actual impacts of currenteducational reforms in Japan. A brief overviewis provided of the basic characteristics of theJapanese education system and trends ineducational reforms since the 1990s. Focusingon curriculum and teaching in primary andsecondary education, the actual impact of theseeducational reforms upon schools is examined. The basic character of present day educationalreforms in Japan may be referred to as educational disarmament, since the emphasisis on considerably loosening up the system interms of reducing curriculum content and thenumber of weekly hours of schooling. This iscontributing to making the educational climateof Japanese schools much milder than before,and is said to have contributed to a loweringof pupil's educational achievement and toeducational opportunities among differentsocial groups becoming more polarized. TheJapanese situation has implications for thefuture orientation of educational reforms inother countries, particularly in theAsia-Pacific region. 相似文献

The aim of the present study was to examine the effects of viscoelastic properties of human tendon structures during stretch - shortening cycle exercise. The elongation of tendon and aponeurosis of the medial gastrocnemius muscle of 26 participants was measured by ultrasonography while they performed ramp isometric plantar flexion up to the voluntary maximum, followed by a ramp relaxation. The relationship between estimated muscle force and tendon elongation during the ascending phase was fitted to a linear regression, the slope of which was defined as stiffness. The percentage of the area within the muscle force-tendon elongation loop relative to the area beneath the curve during the ascending phase was defined as hysteresis. In addition, maximal voluntary concentric contractions at 2.09 and 3.14 rad x s(-1) with and without prior eccentric contractions were performed. The difference in the concentric torque at equivalent joint angles with and without prior eccentric contractions (i.e. pre-stretch augmentation) was negatively correlated with stiffness (P < 0.05) and hysteresis (P < 0.05). Furthermore, there was a higher correlation between the pre-stretch augmentation and the viscoelastic properties index--that is, the sum of normalized score values of stiffness and hysteresis (P < 0.01)--than with either stiffness or hysteresis alone. The results of this study suggest that performance during stretch-shortening cycle exercise is significantly affected by the viscoelastic properties of the tendon structures. 相似文献
