从《喜福会》看中美文化差异

生活在不同文化背景下的人们,由于不同的思维方式和价值观念,在交往过程中难免会产生矛盾。本文以此为切入点,借助爱德华.霍尔关于高背景文化和低背景文化的研究成果,对大量存在于《喜福会》中的文化隔阂和冲突现象进行解析。事实说明,不同文化间的交往需要相互尊重和理解。爱和真诚永远是沟通心灵的桥梁、连接世界的纽带,是全世界不同文化背景下人们的共同心声。     

Selective protection of cells against X-irradiation. Isoproterenol protects only those cells that possesβ-adrenoreceptors

Summary In mixed culture of Chinese hamster fibroblatst, clone 431, and transformed murine L fibroblasts, clone B-82, isoproterenol was found to protect only 431 cells against ionizing radiation. It was shown that 431 cells, in contrast to B-82 cells, possess-adrenoreceptors, and the radioprotective effect of isoproterenol can be realized only if this agent interacts with-adrenoreceptors coupled with the cAMP system. Since malignization often causes the disappearance of-adrenergic and other hormone receptors, the combined culturing and irradiation of the cells studied can be regarded as a model of the growth of malignant cells (B-82) among normal tissue cells (431 cells) under conditions of radiation therapy. A possibility of selective protection against radiation damage of normal tissue cells, with retention of the former radiosensitivity of tumor cells, is discussed.     

论中西管理文化融合创新的趋同

中西管理文化的融合创新，应立足各自传统管理文化原创中的现代价值，结合世界经济一体化发展的需要，进行现代管理文化理念的创新，并且在管理实践融合创新的基础上实现理念与认识的趋同。     

论唐代诗人的多维人学价值观与创作多样性

唐代诗歌从题材内容到风格特点呈现多元化色彩，既有政治、经济等社会因素。也与诗人特定生活环境有关，但最重要的原因，还在于其思想化的相对开放、明、活跃，建构了诗人多元化的人学价值观。他们受多维人学价值取向影响，常常在特定条件下，对其思想化心理加以调节、反思甚至重构，并把其复杂内涵真实反映到诗歌创作中，从而形成作品从题材内容到风格的多样性。     

中西文化交融的澳门文化

澳门文化的最大特点是中西文化交融.历史是文化的源头,澳门文化的特点在澳门四百余年历史发展中自然形成,是历史演进的必然结果.澳门中西文化交融的特点反映在诸多方面:宗教方面、语言方面、建筑艺术方面、风俗方面,等等.     

少数民族文化英语教学中女教师的角色优势

宋词创作观念矛盾与词文学美学体征的变化

作为一代文学之胜的宋词发展流变是一个充满矛盾同时也是充满了活力的进程:在审美观念上,虽然雅化潮流成为一种强势往前推进,但是,俗词的创作传播作为一种源于市井民间的活力涵养着词的生命肌体;理性上的拒斥与实践的热衷这一心理矛盾使宋词从政治教化的重负中逃逸出来,保持一种感性鲜活的审美品质;执着悲哀与超越悲哀两极的情感趋向冲撞对流衍化出宋词丰富多采的审美形态;在性别上,一种整合了双性特点的的抒情范式使宋词具有了更为隽永的滋味;文体上虽有尊体与破体之辩,但在创作实践中,词的破体而行却为词带来了多元多姿的审美风貌;风格上婉约与豪放的消长变化这组过去探讨的最多的矛盾则更多的和以上五组矛盾有着密切的关联。

红豆草抗赖氨酸加苏氨酸愈伤组织变异系的选择和分析

利用红豆草不胚轴诱导的胚性愈伤组织，经过化学诱变和筛选，得到一个抗赖氨酸加苏氨酸（ＬＴ）的愈伤组织变异系，ＬＴ抗性愈伤组织在脱离选择压６个月后，仍表现出１．５倍于野生型的抗性。ＬＴ抗性可通过再生植株传递到次级愈伤组织，抗性细胞中游 离赖氨酸、苏氨酸、蛋氨酸及异氨酸都有较大提高，分别为野生型细胞的５３、５４、１．３９和４．０７倍。抗性细胞和野生型细胞中天冬氨酸激酶的总活性相近，但前者对赖氨酸的反馈抑     

Synergistic effect of acute hypoxia on flow-induced release of ATP from cultured endothelial cells

Human umbilical vein endothelial cells (HUVECs) in primary cultures were perfused under normoxic or hypoxic conditions. These cells were stimulated twice for 3 min by increased flow (from 0.5 to 3.0 ml/min). Under hypoxic conditions the basal release of ATP was the same as under normoxic conditions, but during increased flow the release was greater (0.58±0.07>0.32±0.04 pmoles/ml/10⁶ cells (+78%), for the first period of stimulation; 0.39±0.05>0.22±0.03 pmoles/ml/10⁶ cells (+79%) for the second period). Further experiments with sequential increments in flow rate showed that under both normoxic and hypoxic conditions, a positive correlation existed between ATP release and the rate of flow but there was always more ATP released under hypoxic conditions regardless of the flow rate.HUVECs in secondary culture (second passage) were similarly stimulated. No differences were observed between normoxic and hypoxic conditions. In both cases, the quantity of ATP released during high flow (0.050±0.004 pmoles/ml/10⁶ cells) was significantly smaller than the quantity of ATP released during low flow (0.09±0.01 pmoles/ml/10⁶ cells).To conclude, since hypoxia alone did not affect ATP release, there appears to be a synergistic relationship between increased shear stress and hypoxia in the stimulation of ATP release from HUVECs. Moreover, the release of ATP under these conditions seems to be a property of highly differentiated endothelial cells.
