我国大学排行研究与实践的进展及评析

大学排行在传统上属于社会评估范畴。近年来,由于多主体的参与与高校改革,大学排行的传统概念与实践逐渐发生着变化。大学排行应该围绕“大学发展”的核心指标展开,构建大学发展性排行指标与评估体系。因为只有大学发展了,才能满足多方需求,更好地实现大学排行多种功能。

口外翼下颌阻滞麻醉的应用解剖学研究

在40侧头预部正中矢状切开标本和60侧下颌骨标本上,按口外翼下颌阻滞麻醉的设计要求,解剖观察了下牙槽神经、舌神经在翼下颌间隙的位置。测量了从下颌管下缘点和下颌角行口外翼下颌阻滞麻醉时的进针深度和角度。测得从下颌骨下缘点的进针深度为37mm;下颌角点的深度为30mm,穿刺针与下颌支后缘之间的角度为31°。对采用该法行口外阻滞麻醉的解剖学要点,优缺点进行了讨论。     

Chinese and Canadian Children's Evaluations of Lying and Truth Telling: Similarities and Dfferences in the Context of pro-and Antisocial Behaviors

The present study compared Chinese and Canadian children's moral evaluations of lie and truth telling in situations involving pro- and antisocial behaviors. Seven-, 9-, and 11-year-old Chinese and canadian children were presented 4 brief stories. Two stories involved a child who intentionally carried out a good deed, and the other2 stories involved a child who intentionally carried out a bad deed. When story characters were questioned by a teacher as to who had committed the deed, they either lied or told the truth. Children were asked to evaluate the story characters' deeds and their verbal statements. Overall, Chinese children rated truth telling less positively and lie telling more positively in prosocial settings than Canadian children, indicating that the emphasis on self-effacement and modesty in Chinese culture overrides Chinese children's evaluations of lying in some situations. Both Chinese and canadian children rated trugh telling positively and lie telling negatively in antisocial situations, reflecting the emphasis in both cultures on the distinction between misdeed and truth/lie telling. The findings of the present study suggest that, in the realm of lying and truth telling, a close relation between sociocultural practices and moral judgment exists. Specific social and cultural norms have an impact on children's developing moral judgments, which in turn, are modified by age and experience in a particular culture.     

完善企业境外投资的财政金融政策支持体系

随着经济全球化的发展,企业跨国投资的步伐愈来愈快。在跨国投资过程中,企业也会面临各种困难与风险。发达国家在企业跨国投资过程中,运用税收、信贷、保险等金融手段对境外投资给予促进和必要的制约,从而分散企业的经营风险。我国企业在跨国投资过程中,也应该借鉴国际经验,建立和完善企业境外投资的税收制度,加大企业信贷优惠政策扶持力度,完善企业境外投资保险制度、企业境外投资准备金制度、中小企业境外投资的融资政策等,以分散企业的经营风险。

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.     

Ecological Mural as Community Reconnection

Murals are particularly visually captivating forms of public art due to their size and accessibility. Mural images also capture public attention and provoke viewers to explore layers of meaning and find hidden stories. They are often in places that people come to visit, study, play, congregate and discuss matters that may relate to the content of the mural. To this end, murals can be effective tools for helping communities think about their environmental issues. This article discusses the Mystic River mural project in Somerville, Massachusetts, USA. It addresses how the local art councils, mural artists, local students, community members and non‐profit organisations collaborated to carry out this ongoing mural project. The purpose of this research is to examine how Mystic River eco‐murals were created, what challenges and benefits the eco‐murals provided, how local social concerns were represented through the eco‐murals, how eco‐murals can continue to promote environmental awareness and inspire youth about their community and the local environment, and how the mural can continue to reflect or affect the meaning of the place. This process can serve as an example for other communities that seek to address their environmental concerns through public art.
