意象历来是诗学研究中的重要课题。在20世纪40年代,九叶诗派诗人、诗学家唐浞通过对诗歌历史与现状的考察,对意象及其特征进行了自己的独特描述,认为意象就是诗歌本身而不只是传达手段,意象是灵魂与意志的凝合,是潜意识与意识之间的桥梁,并认为凝定的“姿”是诗歌意象的形态特征。 相似文献

人们阅读语符文本会产生辨味审美,就因为语符具有一种生成味象的机制,这种机制源于饮食生活。饮食生活作为味象生成的根基,其通过交感、第二信号系统及联觉通感等多种途径实现语符的味象生成,从而达成辨味审美。 相似文献

In this article, the authors borrow from anti-oppressive education theory for its potential to disrupt how students visually conceive sporting bodies and to problematize the teaching and learning of these bodies within undergraduate physical education (PE) programs. Fourteen photo stories produced by students enrolled in PE programs at two universities were analysed using a semiotic approach to excavate the emergent themes of sporting bodies from the narratives. Relying on Kumashiro's anti-oppressive educational theoretical framework, the authors found that most of stories reified discursive practices that (re)produce gender oppression in sport. Despite these findings, the authors also discovered anti-oppressive pedagogies are useful for teaching against the body oppressions conveyed in the photo stories. How anti-oppressive education informs other areas of PE should be examined in the future. 相似文献

This paper explores how a group of undergraduate Human Movement Studies (HMS) students learnt to know about the body during their four-year academic programme at an Australian university. When students begin an undergraduate programme in HMS they bring with them particular constructions, ideas and beliefs about their own bodies and about the body in general. Those ideas and beliefs are often challenged, disrupted or reinforced according to discourses and practices to which students are exposed and which they experience throughout their programme of study. The courses that these students take in their in HMS degree programme present to them different perspectives about health and the body. Some perspectives take the status of taken-for-granted truths and others are dismissed or ignored. Taking a Foucauldian perspective, this paper explores the dominant discourses and practices to which this group of students was exposed during their four years of academic formation, and the influences that this exposure might have upon their construction of the body and their formation as pre-service Health and Physical Education (HPE) teachers. The participants in this study were 14 students, 11 females and 3 males, aged between 18 and 26 at the time of the first interview. The data used for this paper were taken from a larger study and were analysed using a content analysis approach. Results suggest that some students may be heavily influenced by certain practices and discourses during their programme of studies, and that they embody dominant discourses of health. Furthermore, a possible change of thinking may occur across their academic programme, as a consequence of their engagement with a few alternative discourses presented during their academic programme, disrupting some of their previous beliefs and knowledge. 相似文献

The aims of this study were to describe normative values and seasonal variation of body composition in female cyclists comparing female road and track endurance cyclists, and to validate the use of anthropometry to monitor lean mass changes. Anthropometric profiles (seven site skinfolds) were measured over 16 years from 126 female cyclists. Lean mass index (LMI) was calculated as body weight?×?skinfolds?x. The exponent (x) was calculated as the slope of the natural logarithm of body weight and skinfolds. Percentage changes in LMI were compared to lean mass changes measured using dual-energy X-ray absorptiometry (DXA) in a subset of 25 road cyclists. Compared to sub-elite and elite cyclists, world class cyclists were (mean [95% CI]) 1.18?kg [0.46, 1.90] and 0.60?kg [0.05, 1.15] lighter and had skinfolds that were 7.4?mm [3.8, 11.0] and 4.6?mm [1.8, 7.4] lower, respectively. Body weight (0.41?kg [0.04, 0.77]) and skinfolds (4.0?mm [2.1, 6.0]) were higher in the off-season compared to the early-season. World class female road cyclists had lower body weight (6.04?kg [2.73, 9.35]) and skinfolds (11.5?mm [1.1, 21.9]) than track endurance cyclists. LMI (mean exponent 0.15 [0.13, 0.18]) explained 87% of the variance in DXA lean mass. In conclusion, higher performing female cyclists were lighter and leaner than their less successful peers, road cyclists were lighter and leaner than track endurance cyclists, and weight and skinfolds were lowest early in the season. LMI appears to be a reasonably valid tool for monitoring lean mass changes. 相似文献

曹禺戏剧中常常运用意象并置的诗化手段将看似散乱的材料进行“聚”与“收”的处理,以达到对材料深层寓意的充分挖掘。其意象并置的运用普遍而又多样;既有相似意象的对等,又有对比性意象的“跳跃衔接”,还有相同意象的多角度重复,它们与剧中浓郁的叙事性相互对抗,形成戏剧的内在结构张力。 相似文献
