文化差异视角下的英汉颜色词的联想

不同的民族由于地理、民俗、宗教及价值观念等方面的差异,在表达同一概念时,词汇被赋予了许多的联想意义。掌握汉英颜色词不同的文化联想意蕴,并且了解产生这些不同联想意义的原因不仅有利于提高英语学习水平,还能促进和加强中西文化之间的交流。     

用工业CT技术测量储层岩芯饱和度分布

认识储层岩石中含油饱和度及饱和度分布,对驱替机理的深入研究是非常重要的。为了搞清储层岩石在驱替过程中的饱和度分布情况,应用工业CT技术,提出了一种储层含油岩芯被驱替后的饱和度分布的CT密度差测量方法。在岩样的同一断面,分别对干岩样、饱和岩样及在驱替后的岩样进行CT扫描,重建相应的断层图象,测量所建图象的灰度值,计算出相应的密度值,用密度差法计算出饱和度及其分布值。在γ射线工业CT机“CD-300BG”上对某油田岩样进行了实际测量,获得的结果说明,采用CT密度差法测量饱和度分布是有效的。该方法与常规驱替法相比较,具有快速、精度高、无损岩样和能模拟地层状态测量等特点,是油田开发、油藏描述和地层评价的一种新的有效方法。     

非期望产出下我国能源消耗产出效率差异研究

提高能源消耗产出效率是新常态下经济发展的必然趋势，随机扰动和外部环境是研究能源消耗产出效率不可回避的问题，而传统的DEA模型无法剔除非期望产出对效率值的影响。本文通过构建四阶段Bootstrap-DEA-Malmquist模型，采用1990~2014年的省际面板数据作为样本数据，通过松弛指标调整能源投入，剔除外部环境和随机因素对能源效率和能源全要素生产率的扰动，并借助Bootstrap随机抽样法进一步减小由于样本差异造成的影响，从静态和动态两个维度测算了中国能源消耗产出效率和全要素生产率。研究发现，外部环境和随机扰动对能源效率的估算具有显著影响，剔除外部环境影响因素后得到的能源效率值、技术效率变化以及全要素生产率变动均有不同程度的下降，而调整初始投入后的技术进步值有所上升。此外，考虑环境因素时，能源效率值下降，但是进一步运用Bootstrap随机抽样法消除随机因素的影响后，能源效率值有所上升。本文的主要贡献在于将环境因素和随机因素从能源效率与能源全要素生产率的测算中剥离，获得更为准确的能源效率值和能源全要素生产率值。     

From the Digital Divide to the Connectivity Dividend Difference: A Connectivity Capital Perspective*

The access divide was once the basic form of the digital divide. The development of Internet infrastructure has narrowed the access divide and increased application coverage, but it has also touched off a connectivity dividend difference. Taking the online market as an example, we examine the sources of the dividend difference and the factors influencing it with in a connectivity framework. We found that the narrowing of the access divide has resulted in enhanced connectivity and platform development, giving people the chance to benefit from transforming the various assets in which they have previously invested into differentiated compound connectivity capital. In the course, the scale and rate of the conversion are affected by two multiplier effects and especially by online platforms. The process is ultimately expressed in the dividend difference.     

A New Feature Selection Method for Text Categorization of Customer Reviews

With the rapid development of e-commerce, online consumer review plays an increasingly important role in consumers’ purchase decisions. Most research papers use the quantitative measures of consumer reviews for statistical analysis. Here we focus on analyzing the texts of customer reviews with text mining tools. We propose a new feature selection method called maximizing the difference. Various classification methods such as boosting, random forest and SVM are used to test the performance of the new method along with different evaluation criteria. Both simulation and empirical results show that it improves the effectiveness of the classifier over the existing methods.     

Decency and the Liberal International (Dis)Order: Moral Limits and the Possibilities of a Global Pluralist Politics

This article analyzes the tension between the liberal ideals of freedom and equality and cultural difference. It argues that decency has become intertwined with the fragility of the liberal international order by providing a problematic threshold of international justice. The idea is that as global pressures mount for protecting the human dignity of persons/peoples, they also congeal or harden decency’s political and social constraints (impartiality, neutrality, and basic rights enforcement) on engaging others. Decency as a moral threshold of international justice, the article claims, has become static or a self-reinforcing limitation. This contradictory decency/dignity dynamic of the liberal international order not only explains how states have aggressively asserted their interests by absorbing these constraints, but also how politics can limit the pragmatic potential to bridge the various social gaps in values and belief systems. This article seeks to conceptualize a pluralist ethos that shows how such constraints can be reimagined as, or turned into, the conditions of possibility/freedom that transition us to a global pluralist politics. It concludes with a discussion of the refugee crisis and Islamism, showing how both cases resonate the felt stigmatization and alienation within the liberal international order.

探析俄汉礼节语言的民族文化差异

俄汉礼节语言的民族差异是两种文化价值观差异的反映。在汉文化中,独特的中华传统和民族文化形成了中国特色的复杂的礼节语言体系。在俄文化中,礼节语言明显带有简单化、模式化和抽象化的特点,这同俄罗斯民族的思维方式密切相关。
