翻译过程思维模式的理性探索

研究翻译过程就是探讨双语转换的认知心理过程,以揭示其思维规律。拟建的翻译模式整合Van Dijk的话语宏观结构理论和Neubert与Shreve的“虚构译本”观点,将七个语篇特征视为译者在解码与构码过程中作调整和变通的参数,旨在动态描述翻译过程。     

谈图书馆文献信息资源建设

文献信息资源的建设与管理是高校图书馆的重要任务,加强图书馆文献信息资源的建设与管理是高校图书馆面临的重要课题。高校图书馆应根据重点学科建设的要求,在加大对藏书建设力度的基础上,加强对期刊、电子文献和虚拟馆藏的建设,同时要加强与院(系)资料室之间的协作。     

我国股改中权证的价格泡沫及影响因素

本文针对我国股改中的百慕大权证提出了新的“模拟树-市场情绪”定价模型。该模型的实证研究结果表明中国权证市场价格存在严重高估;加入市场情绪指标后,通过建立多元回归模型得到了对于实际价格的显著的拟合结果,有力地解释了超出权证理论价格的实际价格所包含的情绪因素。本文最后对权证价格高估的原因及权证未来的走势进行了分析。     

Does the social security fund help non-financial enterprises to transform from the virtual to the real?

At its 19th National Congress, the Communist Party of China vowed to “strengthen the financial sector’s ability to serve the real economy.” However, many studies provide evidence of the opposite trend, a problematic “transition from the real to the virtual,” among Chinese enterprises. Meanwhile, the investment efficiency of China’s Social Security Fund (SSF), a public fund, attracts much attention. In this context, we use A-share listed companies in China from 2009 to 2018 to study the relationship between holding by the SSF and enterprise financialization. We find that SSF holding significantly inhibits financialization and that this effect is non-linear. Mechanism analysis indicates that SSF holding suppresses enterprises’ financialization mainly by improving their governance. Moreover, SSF holding more strongly inhibits small-scale (vs. large-scale), state-owned (vs. non-state-owned), and non-eastern (vs. eastern) enterprises in China. Furthermore, SSF holding can alleviate corporate value impairment caused by financialization. The conclusions enrich theoretical research and provide empirical evidence that may help regulatory authorities to guide investment by enterprises and prevent financial risks.     

Carbon Trading with Imperfectly Observable Emissions

The Kyoto Protocol foresees emission trading but does not yet specify verification of (uncertain) emissions. This paper analyses a setting in which parties can meet their emission targets by reducing emissions, by investing in monitoring (reducing uncertainty of emissions) or by (bilaterally) trading permits. We derive the optimality conditions and carry out various numerical simulations. Our applications suggest that including uncertainty could increase compliance costs for the USA, Japan and the European Union. Central Europe and the Former Soviet Union might be able to gain from trading due to higher permit prices. Emissions trading could also lower aggregate uncertainty on emissions.
