俄罗斯文化视角下的《多余的话》

瞿秋白的《多余的话》是在俄罗斯文化思想影响下完成的,蕴涵着多余人心态和忏悔意识等异质文化特征。但是,瞿秋白的政治身份和当时的政治氛围导致人们对《多余的话》的误读。只有深刻揭示出这种异质文化特征与单一政治视角的矛盾性和复杂性,才能真正理解《多余的话》及其文学思想。

Adapting to change in the higher education system: international student mobility as a migration industry

ABSTRACT

Of late there has been considerable interest in understanding international student mobility, and this has tended to focus on the perspective of the students who take part in this mobility. However, international students are part of a considerable migration industry comprised of international student recruitment teams, international education agents and other institutions selling an education overseas (such as the British Council in a UK context) and as yet there is little research which analyses these relationships. This paper investigates a series of interviews with international office staff to examine the methods they use to recruit international students, and in particular the relationship that they have with international education agents who work with them on a commission basis. It focuses on recent changes to the UK visa system which have led to a decline in the numbers of Indian students choosing to study towards a UK higher education. However, it also reveals that some universities have managed to avoid this trend. This paper investigates why this is the case, demonstrating that there is a need to think about the intersections between migration industries, visa regulations and international student mobility.     

异质间性:当代设计审美价值透视

异质间性指系统中矛盾要素之间的互动与张力。异质间性的交融视域,构成了当代设计及其审美的核心价值,并折射出当代社会多元文化共生共融的理念和方法。从异质间性视角解析与透视审美价值,有助于把握人类造物、社会生活、审美文化等当代性特质。     

对科技效用的反思——兼谈科技主体的责任

添加助剂的负载型双金属簇催化剂的CO加氢反应性能研究

利用助剂Ｋ２Ｃｏ３、Ｃ（５２）ＣＯ３、Ｃｕ（ＮＯ３）２和Ｍｎ（Ｎｏ３）２对担体γ－Ａｌ２Ｏ３表面进行修饰以及ＫＣｌ助剂对γ－Ａｌ２Ｏ３和ＳｉＯ２相体表面修饰，制成负载型Ｆｅ－Ｃｏ双金属簇催化剂。考察其ＣＯ加氢反应催化活性和选择性，比较催化刑中添加助刑对ＣＯ转化率和低碳烯烃选择性的影响，为制备高活性和选择性的ＣＯ加氢催化剂探索新的途径。     

基于改进信息交易概率模型的信息风险测度研究

准确测度信息不对称是研究金融市场信息不对称问题的基础。在详细考察经典的信息交易概率模型的建模过程和假设条件的基础上,针对信息交易者和非信息交易者在不同信息状态下的订单提交状况,提出考虑外生信息状态概率、异质期望和交易活跃度的改进的信息交易概率模型;通过带机制转换的向量自回归模型估计外生信息状态概率,综合考虑多方面的市场交易信息,提高模型估计的准确性。实证结果表明,改进的信息交易概率模型可以较好地刻画证券市场的信息不对称程度。从截面上看,信息交易概率与标的资产的垄断优势和话题性相关,垄断优势越强的股票信息交易概率越低,话题性越强的股票信息交易概率越高;从时间上看,信息交易概率的变化受公告信息的影响,公告信息发布前的信息交易概率较高,公告信息发布后的信息交易概率较低。因此,在防范信息风险时,应重点关注话题性较强的版块,特别是股价比较容易受舆论影响波动的个股;同时,在公告信息发布之前的时段,应对市场波动和信息动向给予更多关注。     

试论《红楼梦》俄译本中异质文化的翻译策略

对《红楼梦》俄译本中反映汉俄思想观念、文化内涵差异词语的翻译研究,分析面对异质文化译者所采取的翻译策略,进而指出异化与归化这两种翻译策略并不是绝对对立的,二者应相互借鉴与结合,才更有利于全球化背景之下的文化交流。     

投资者异质信念与证券市场盈余公告效应研究

盈余公告效应异象在各国资本市场普遍存在,行为金融理论中的投资者异质信念视角能较好地解释该异象。实证结果表明：投资者异质信念与盈余公告前后短期内累积超额收益率显著正相关,与盈余公告后长期累积超额收益率显著负相关;其中,低盈余质量强化了这种负向影响。投资者异质信念程度越大、盈余质量越低,长期累积超额收益率越小。     

The Emergence of Reactive Strategies in Simulated Heterogeneous Populations

The computer simulation study explores the impact of the duration of social impact on the generation and stabilization of cooperative strategies. Rather than seeding the simulations with a finite set of strategies, a continuous distribution of strategies is being defined. Members of heterogeneous populations were characterized by a pair of probabilistic reactive strategies: the probability to respond to cooperation by cooperation and the probability to respond to defection by cooperation. This generalized reactive strategy yields the standard TFT mechanism, the All-Cooperate, All-Defect and Bully strategies as special cases. Pairs of strategies interacted through a Prisoner's Dilemma game and exerted social influence on all other members. Manipulating: (i) the initial distribution of populations' strategies, and (ii) the duration of social influence, we monitored the conditions leading to the emergence and stabilization of cooperative strategies. Results show that: (1) The duration of interactions between pairs of strategies constitutes a crucial factor for the emergence and stabilization of cooperative strategies, (2) Unless sufficient learning intervals are provided, initializing the simulations with cooperative populations does not guarantee that cooperation will sustain.
