思维模式差异与英文写作

东西方思维模式存在差异。西方人遵循单向式思维模式,而东方人则遵循多向式思维模式。表现在写作上,西方人倾向借助线性发展模式,而东方人则常使用螺旋型模式展开语段。思维模式的差异导致了许多中国学生在英文写作中缺乏连贯性和逻辑性。为改变这一现状,教师可引导学生运用写作图式,尝试将"支架"理论引入写作教学,加强写作连贯性和逻辑性的训练。     

在存在性与个人性之间:课程本质的再思考

在新课程改革推进的过程中还存在一些问题,反映出一些教师对课程本质和新课程要求的理解仍然存在偏差.从人们认识课程的思维方式上去深究产生这些偏差的原因,我们认为是认识课程的方式在"存在性"到"个人性"两端上摇摆导致了教师对新课程的疑惑,只有在存在性与个人性之间来思考课程,才可能接近课程的本质,更好地实现新课程改革的要求.

英德国家科研实验室机构的体制机制比较分析及借鉴

合理的管理体制与运行机制对保障国家科研实验室机构的建设和运行具有重要作用。该文从英德两国的国家科技体制简况、科研机构管理体制、运行机制等方面进行比较分析,着重于科研组织结构、人事管理制度、开放和流动机制、评估机制等方面。在大力倡导自主创新的形势下,新建国立和公立科研机构应大胆借鉴吸收外国先进经验,探索适合我国国情的科研机构管理体制和运行机制创新之路。     

用拉压不同模量理论计算支座移动引起的超静定结构内力

For statically indeterminate structure, the internal force will be changed with the translation of the supports, because the internal force is related to the absolute value of the stiffness EI. When the tension is different with the compression modulus, EI is the function of internal force and is not constant any more that is different from classic mechanics. In the other words, it is a nonlinear problem to calculate the internal force. The expression for neutral axis of the statically indeterminate structure was derived in the paper. The iterative program for nonlinear internal force was compiled. One case study was presented to illustrate the difference between the results using the different modulus theory and the single modulus theory as in classical mechanics. Finally, some reasonable suggestions were made for the different modulus structures.     

Predicting transition and adjustment to college: biomedical and behavioral science aspirants’ and minority students’ first year of college

The purpose of this study is to explore key factors that impact the college transition of aspiring underrepresented minority students in the biomedical and behavioral sciences, in comparison with White, Asian students and non-science minority students. We examined successful management of the academic environment and sense of belonging during the first college year. Longitudinal data were derived from the Higher Education Research Institute’s (HERI) 2004 Cooperative Institutional Research Program (CIRP) Freshman Survey and the 2005 Your First College Year (YFCY) Survey. Using a reformulation of the integration model (Nora, Barlow, and Crisp, 2005), we find concerns about college financing, negotiating family support and responsibility, and campus racial dynamics (perceived and behavioral) affect student adjustment and sense of integration in the first year. This study was made possible by the support of the National Institute of General Medical Sciences, NIH Grant Number 1 RO1 GMO71968-01.

Tandem Biocatalysis by CotA-TJ102@UIO-66-NH2 and Novozym 435 for Highly Selective Transformation of HMF into FDCA

2,5-Furandicarboxylic acid(FDCA) is a potential biorenewable chemical for applications including plastics, polyamides, drugs, etc. The selective biosynthesis of FDCA from 5-hydroxymethylfurfural(HMF) by a specific enzyme poses a great challenge. In this study, we reported an efficient strategy to produce FDCA from HMF by the tandem biocatalysis of laccase(Cot A-TJ102@UIO-66-NH_2) and Novozym 435. For the first step, a nanoparticle metal–organic framework was synthesized as a carrier to immobilize Cot A-TJ102@UIO-66-NH_2, which was assigned for the production of 5-formyl-2-furancarboxylic acid(FFCA) and featured an enzyme loading of 255.54 mg/g, specific activity of 135.90 U/mg, and solid loading ratio of 99.65%. Under optimal conditions, an ideal FFCA yield of 98.5% was achieved, and the Cot A-TJ102@UIO-66-NH_2 presented a high recycling capacity after 10 cycles. For the second step, Novozym 435 was applied for the further conversion of FFCA into FDCA, presenting a high FDCA yield of 95.5% under the optimized conditions. Novozym 435 also exhibited a high recyclability after eight cycles. As a result, the tandem biocatalysis strategy provided a 94.2% FDCA yield from HMF, indicating its excellence as a method for FDCA production.     

Degradation of chlorophenol by in-situ electrochemically generated oxidant

INTRODUCTION With the development of industry, more and more pollutants are discharged into environment, among them, phenolic wastes are typical contami-nants considered to be hazardous and top priority toxic pollutants listed by the USEPA. They are toxic even at low concentration. Due to their biorefractory, bioaccumulation and carcinogenic potential, the treatment of these contaminants is very important in environmental protection. Various technologies and processes have been tried …     

试论吴宓的孔教观

在新文化运动后期,吴宓受西方新人文主义的影响,针对新文化运动和孔教活动,站在与新文化运动反孔批儒相对立的立场,通过学理辩析,凸现孔子在中国文化的中心地位,阐明孔教是一种具有宗教性的人文道德学说,并站在中西古今文化比较的高度,提出了以孔教为基础,融合世界上其他宗教和哲学的中国文化重建构想,这对于我们今天正确理解孔子儒学以及儒教的本质有重要参考价值和思想启迪.
