生态美学的“反现代性”研究

生态美学作为一门新兴的学科领域,在我国的文化传统中,存在着大量的反映、描绘大自然之美以及人与自然关系“反现代”的经典艺术作品,为人们提供了摆脱生存环境困扰的宝贵的生态智慧,但生态美学强调自然信仰的“生态整体主义”,并不是对人类自身的否定,而是以生命为基点,重建人与世界的生态审美关系。     

Bridging western and First Nations thought: Balanced education in Whitehead's philosophy of organism and the sacred circle

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.     

大学生篮球运动负荷的定量

运动训练负荷是影响机体免疫功能的重要因素之一.教师、教练员进行篮球训练应遵循动作技能形成的规律、人体生理机能活动能力变化的规律和人体机能适应性规律,依据外部负荷指标和内部负荷指标,通过对身体形态、身体机能、身体素质水平测定确定运动负荷量和负荷强度.     

《文心雕龙》中的作品有机论

作品有机构成论是中外文论中的重要内容,中国古代文论中的作品有机构成理论更是独具特色。刘勰在其《文心雕龙》中把文学作品比作人体构成,认为文学作品自身形成一个如人体一般的有机体,即它在内容上是统一完善的,在形式上是完整和谐的。这一比喻不仅能深刻地揭示出文学作品所具有的特点,而且显示了中国古代文论中的人学资源,对于发展和建设中国特色的文艺学具有重要的借鉴意义。

Ciona intestinalis as an emerging model organism： its regeneration under controlled conditions and methodology for egg dechorionation

The ascidian Ciona intestinalis is a model organism of developmental and evolutionary biology and may provide orucial clues concerning two fundamental matters, namely, how chordates originated from the putative deuterostome ancestor and how advanced chordates originated from the simplest chordates. In this paper, a whole-life-span culture of C. intestinalis was conducted. Fed with the diet combination of dry Spirulina, egg yolk, Dicrateria sp., edible yeast and weaning diet for shrimp, C. intestinalis grew up to average 59 mm and matured after 60 d cultivation. This culture process could be repeated using the artificially cultured mature ascidians as material. When the fertilized eggs were maintained under 10, 15, 20, 25 ℃, they hatched within 30 h, 22 h, 16 h and 12 h 50 min respectively experiencing cleavage, blastulation, gastrulation, neurulation, tailbud stage and tadpole stage, The tadpole larvae were characterized as typical but simplified chordates because of their dorsal nerve cord, notochord and primordial brain. After 8-24 h freely swimming, the tadpole larvae settled on the substrates and metamorphosized within 1-2 d into filter feeding sessile juvenile ascidians. In addition, unfertilized eggs were successfully dechorionated in filtered seawater containing 1% Tripsin, 0.25% EDTA at pH of 10.5 within 40 min. After fertilization, the dechorionated eggs developed well and hatched at normal hatching rate. In conclusion, this paper presented feasible methodology for rearing the tadpole larvae of C. intestinalis into sexual maturity under controlled conditions and detailed observations on the embryogenesis of the laboratory cultured ascidians, which will facilitate developmental and genetic research using this model system.     

Whitehead and the Implications of the Process Metaphor for Mathematics

In Principia Mathematica Whitehead and Russell erected one of the cornerstones of modernist philosophy of mathematics. However, as an epistemological project seeking to secure the foundations of mathematics, this attempt failed, as Whitehead acknowledged. His later work in process philosophy represented a new direction. Although not explicitly a philosophy of mathematics, it provides a suggested metaphor for philosophy of mathematics. This paper explores the possible implications of organismic and process philosophy, both for the philosophy of mathematics, and for mathematics education and teaching.
