关于牛顿“碑文”翻译的一个争论     

隆寅 《河池学院学报》2011,31(6):10-12

诗人蒲柏曾给牛顿拟过一个碑文,后来虽未予采用,但该诗却流传甚广,很多关于牛顿的文章都引用过它。其后,另一个英国诗人J．C．斯奎尔,按同样的形式又续了一首诗。对于后一首诗准确的理解和翻译,曾经引起了一场很热烈的争论。  相似文献

“5C”语篇分析模式在大学英语阅读教学中的应用     

吴军俐 《昆明师范高等专科学校学报》2015,(1)

将“5C”语篇分析模式运用于大学英语课堂教学,可以从微观和宏观两个方面进行分析。微观结构分析有助于学生对篇章的理解由词、句层面向语篇层面拓展,培养学生理解句与句、段与段之间的衔接及逻辑关系,注重对篇章的整体理解;宏观结构分析则从篇章结构、文化及语境等方面引导学生理解主题思想和作者意图,发掘深层内涵。  相似文献   

Open access to data: An ideal professed but not practised     

Patrick Andreoli-Versbach  Frank Mueller-Langer 《Research Policy》2014

Data-sharing is an essential tool for replication, validation and extension of empirical results. Using a hand-collected data set describing the data-sharing behaviour of 488 randomly selected empirical researchers, we provide evidence that most researchers in economics and management do not share their data voluntarily. We derive testable hypotheses based on the theoretical literature on information-sharing and relate data-sharing to observable characteristics of researchers. We find empirical support for the hypotheses that voluntary data-sharing significantly increases with (a) academic tenure, (b) the quality of researchers, (c) the share of published articles subject to a mandatory data-disclosure policy of journals, and (d) personal attitudes towards “open science” principles. On the basis of our empirical evidence, we discuss a set of policy recommendations.  相似文献   

(International) R&D collaboration and SMEs: The effectiveness of targeted public R&D support schemes     

Hanna Hottenrott  Cindy Lopes-Bento 《Research Policy》2014

This study analyses the impact and effectiveness of targeted public support for R&D investment at the firm level. We test whether the policy design aiming at incentivizing (international) collaboration and R&D in SMEs achieves input as well as output additionality. Our results show that the targeted public subsidies trigger R&D spending, especially so in internationally collaborating SMEs. We further evaluate the different impact of privately financed and publicly induced R&D investment on innovation performance. The results confirm that the publicly induced R&D is productive as it translates into marketable product innovations. While both types of R&D investments trigger significant output effects, the effect of policy-induced R&D investment on sales from market novelties is highest for international collaborators as well as for SMEs.  相似文献   

“P53 Codon 72 Single Base Substitution in Viral Hepatitis C and Hepatocarcinoma Incidences”     

Emad F. Eskander  Ahmed A. Abd-Rabou  Shaymaa M. M. Yahya  Ashraf El Sherbini  Mervat S. Mohamed  Olfat G. Shaker 《Indian journal of clinical biochemistry : IJCB》2014,29(1):3-7

Viral infection with hepatitis C virus (HCV) has a high propensity in becoming chronic and it is the major cause of hepatocellular carcinoma (HCC) worldwide. This review was basically established to illustrate the putative role of the P53 gene Arg72Pro polymorphism on various cancer models and viral infections, focusing on HCV and HCC incidences. Authors studied the 72 G/C single base substitution of P53 gene at codon 72 using various polymorphic techniques. Intriguingly, authors investigated that the P53 codon 72 plays a crucial role as risk factor in several cancer models. Others found that there is no association between codon 72 genotypes and HCV disease severity or liver cancer. Moreover, the lack of a significant relationship between this polymorphism and risk of HCC shows that it does not predispose towards hepatocarcinogenesis and the frequent loss of the proline allele in HCV-associated carcinogenesis of the liver plays some critical role in hepatocarcinogenesis. Amazingly, there is a significant correlation between male homozygotes for P53 72Pro with HCV type 1b infection. However, there was no significant difference between the P53 polymorphism and HCV genotypes 2a and 2b. It was concluded that the P53 gene polymorphism at codon 72 has been investigated as potential risk factor in several cancer models and HCV infections.  相似文献
