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。

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.

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.     

招生规模核定方法评析

本文对各主要规模核定方法逐一作了评述并分析其适用条件。研究发现,不存在公认完善的教育规划方法论,教育规划仍处于艺术的状态而没有成为精确科学。任何核定方法都是为一定的发展目标服务的,目标的确定及其轻重缓急的安排,反映了具体条件下招生规模对高等教育在社会经济发展过程中作用的期待。

论“二冯”“比兴”说的内涵及影响

作为“虞山诗派”“疑丞”的海虞“二冯”,创造性地阐释“比兴”之义,并将其与“温柔敦厚”的“诗教”传统融为一体,概括了诗歌“以比兴寄美刺”的体用本质。其“比兴”说虽有狭隘之嫌,却也深合我国古代的论诗传统,对清代诗词的创作和理论发展都产生了重要影响。
