1928年,鲁迅与创造社、太阳社发生了革命文学论争,这场论争给双方乃至整个左翼文艺界留下了深刻的教训,但“异中求同”使双方实现了“人和”。使左翼文艺界内部的原动力被激活,使左翼文艺界实现了“优胜劣汰”,使进步知识界明确、认同了无产阶级文艺和文化的存在合理性,进而为中国左翼文学的发生奠定了坚实的理论基础和相应的舆论准备。 相似文献

Bridging western and First Nations thought: Balanced education in Whitehead's philosophy of organism and the sacred circle 总被引:1,自引:0,他引:1
Robert Regnier 《Interchange》1995,26(4):383-415
The sacred circle offers a perspective for interpreting and theorizing about human development valuable in shaping the education of First Nations and non-First Nations students. For those of us in a western materialist culture who are interested in coming to understand what the sacred circle might offer, it is necessary to address assumptions in our own culture. This paper proceeds in four parts to facilitate such an understanding. Part One formulates the importance of a culturally self-critical approach to understanding education based in the sacred circle. Part Two presents the sacred circle as a pattern used to interpret meaning in First Nations education. Part Three examinesinterconnectedness through (a) whitehead's criticism of western scientific epistemology and his idea of education for balanced development, and (b) through the creator, mother earth and the Four Directions reflected in the sacred circle. Part Four interprets aholistic apprehension approach to education based in (a) Whitehead's notion's of intuition and imagination for balanced development from the sacred circle perspective, and (b) through the sacred circle in the vision quest ceremony. 相似文献

鉴于矮塔斜拉桥受力性能的特殊性,引入增量动力分析(IDA)和拉丁超立方体抽样(LHS)评估该结构在地震激励下发生损伤的风险概率。首先采用LHS考虑桥梁构件材料的随机性,与事先选取的地震波相结合形成桥梁-地震动样本集合;其次在确定桥梁有限元模型主要构件损伤指标的基础上采用基于蒙特卡罗(MC)抽样的IDA进行地震易损性分析和地震风险概率评估。为验证方法的正确性和有效性,对一预应力混凝土独塔双索面矮塔斜拉桥结构模型进行地震风险概率评估,结果表明:该方法既充分考虑了材料和地震输入双重随机性又避免了繁琐的积分过程,同时也提高了工程计算的效率及精度。 相似文献

The aim of this study was to investigate, for typical shoes and surfaces used in tennis, the relative role of the shoe and
surface in providing cushioning during running. Five test surfaces ranging from concrete to artificial turf were selected,
together with two shoe models. Impact absorbing ability was assessed mechanically using drop test procedures and biomechanically
using peak magnitude and rate of loading of impact force and peak in-shoe pressure data at the lateral heel. Differences in
biomechanical variables between shoe-surface combinations were identified using a two-way ANOVA (p < 0.05). Mechanical test results were found to rank the surfaces in the same order regardless of the shoe model, suggesting
that the surface is influential in providing cushioning. However, for all mechanical and biomechanical (p < 0.05) variables representing impact absorbing ability, it was found that the difference between shoes was markedly greater
than the differences between surfaces. The peak heel pressure data were found to rank the surfaces in the same order as the
mechanical tests, while impact force data were not as sensitive to the changes in surface. Correlations between mechanical
and biomechanical impact absorption highlighted the importance of testing the shoe-surface combination in mechanical tests,
rather than the surface alone. In conclusion, mechanical testing of the shoe-surface combination was found to provide a strong
predictor of the impact absorbing ability during running if pressure data were used. In addition, for typical shoe-surface
combinations in tennis, the shoe was found to have more potential than the surface to influence impact loading during running.
Finally, in-shoe pressure data were found to be more sensitive than force plate data to changes in material cushioning. 相似文献

在电子技术教学中,分析运算放大器系统时,应根据运算放大器系统的反馈情况,判断它的工作状态;分析工作状态时,要充分考虑运放系统是处于线性区还是饱和区。线性区可按虚短或虚地原则处理,饱和时不能按虚短原则处理,应用“虚短”和“虚地”时应注意“虚短”是“虚地”的特殊形式。 相似文献
