Rapid visual processing by college students in reading irregular words and phonologically regular pseudowords presented singly and in contiguity

Using normal adult readers, this study examined the relative involvement of magnocellular and parvocellular processes in reading English phonologically regular pseudowords and irregular words presented in isolation and in contiguity from left to right. The data showed that a low temporal frequency visual measure that implied more parvocellular involvement was active in processing irregular words presented singly and pseudowords presented in contiguity. However, the results failed to show the involvement of the magnocellular pathway (as implicated by low spatial and/or high temporal frequency visual measures) in reading words presented in contiguity from left to right. The discrepancy was discussed in terms of the sensitivity of the tasks used in testing the two pathways.     

浅论民族院校校园文化存在的问题及对策

民族院校的校园文化应有鲜明特色。但在当前各民族院校校园文化建设中，普遍存在发展的封闭性、无突出的民族特性、文化冲突性、校园文化活动不丰富、物质文化建设的投入不足等问题。要解决这些问题，应从提升学校形象，贯彻价值观念，弘扬民族精神，突出民族特色，合理整合文化冲突，丰富校园文化活动，改善物质文化等方面着手，构建和提升富有特色的民族院校的校园文化。

不合事体情理是当代小说难出经典名著的重要症结——以著名作家路遥刘庆邦欧阳黔森的三部中篇小说为例（下）

当代小说创作的表面繁荣主要体现在数量的庞大上,但在质量方面却很难产生经典名著。仅以路遥的《人生》、刘庆邦的《到城里去》、欧阳黔森的《白多黑少》三部中篇获奖小说为例,其间悖情悖理的虚假失真之处俯拾皆是,大有滥用“戏不够,神仙凑”之胡编乱造的拙劣平庸手法之嫌。从个人方面来说,古典文化功底浅薄限定了往高精尖处发展的空间,在作品中便裸露出捉襟见肘之窘和山穷水尽之憾。从社会因素衡定,则与转型期所普遍存在的浮躁心态挚密相关。急功近利,多写快出,是假冒伪劣顽疾在小说创作领域的真实体现,致使作品情节虚假问题变成了一种习以为常、司空见惯的集体无意识。此项流弊应及早引起文学界领导层和作家们自身的高度重视和认真反思,以便对症下药,制订出切实可行的改革措施,呼唤并敦促新时期文学巨人的早日脱颖而出。     

3D thermoelasticity solutions for functionally graded thick plates

Thermal-mechanical behavior of functionally graded thick plates, with one pair of opposite edges simply supported, is investigated based on 3D thermoelasticity. As for the arbitrary boundary conditions, a semi-analytical solution is presented via a hybrid approach combining the state space method and the technique of differential quadrature. The temperature field in the plate is determined according to the steady-state 3D thermal conduction. The Mori-Tanaka method with a power-law volume fraction profile is used to predict the effective material properties including the bulk and shear moduli, while the effective coefficient of thermal expansion and the thermal conductivity are estimated using other micromechanics-based models. To facilitate the implementation of state space analysis through the thickness direction, the approximate laminate model is employed to reduce the inhomogeneous plate into a homogeneous laminate that delivers a state equation with constant coefficients. The present solutions are validated by comparisons with the exact ones for both thin and thick plates. Effects of gradient indices, volume fraction of ceramics, and boundary conditions on the thermomechanical behavior of functionally graded plates are discussed.
