二语动机自我系统与大学英语四级成绩的关系

本文基于问卷调查的数据,分析了二语动机自我系统与全国大学英语四级(以下简称CET4)成绩的关系。研究结果表明:不同CET4成绩的学生,理想二语自我和二语学习经历之间有显著差异,然而这些学生的应该二语自我却没有显著性差异;理想二语自我和二语学习经历与CET4成绩呈显著正相关,应该二语自我与CET4成绩之间相关性不显著;理想二语自我、二语学习经历与CET4成绩之间有显著回归关系,理想二语自我的影响力高于二语学习经历,应该二语自我与CET4成绩没有显著回归关系。鉴于二语动机自我系统与CET4之间的关系,在教学过程中,教师要引导学生正确对待CET4成绩,建构积极的理想二语自我,丰富学生的学习体验,提高英语水平。       

Organization communication regarding ISO 26000 practices in South Korea: focusing on the enlarged scope

ISO 26000, issued on November 1, 2010, has enlarged the scope of social responsibility (SR) from corporations to all types of organizations. This article examines how organizations that traditionally have not been concerned with this term, such as public or governmental institutions and nonprofit organizations, interpret this new standard and the notion of SR, especially in the South Korean context. For this research, we observed the SR-related reports and media activity of seven Korean organizations: Korean Standards Association (KSA), the Ministry of Knowledge Economy (MKE), Gangdong-gu Office (GDG), Christian Ethics Movement of Korea (CEMK), LG Electronics Union (LGEU), Collective Action (CA), and Working Together Corporation (WTCO). We also carried out interviews with experts in these organizations, who largely work on the subject. Using the organizing theory frame (enactment–selection–retention) of Karl E. Weick, we analyzed three elements of the organizational communication of these institutions: strategy, ISO 26000 messaging, and receivers of the information. ISO 26000 was first actively used in public organizations (e.g., KSA, MKE, and GDG) as a policy tool to expand the concept to all aspects of Korean society, and was later used in certain nonprofit organizations (e.g., LGEU and CEMK) as a new paradigm, creating new concepts such as union SR and churches’ SR that partially accept the international standard in different contexts. Some civil societies, such as CA and WTCO, observe the phenomenon in a passive way to see if it could promote the social values of their organizations. Lastly, in spite of the scope enlargement, we note that SR is still in the range of corporate SR, and the application process in South Korea shows that the social aspect is more easily ignored than the economic and environmental aspects.     

Random Weighting Estimation for Quantile Processes and Negatively Associated Samples

This article presents new theories of random weighting estimation for quantile processes and negatively associated samples. Under the condition that X ₁, X ₂,…, X _n are independent random variables with a common distribution, the consistency for random weighting estimation of quantile processes is rigorously proved. When X ₁, X ₂,…, X _n are not independent of each other, random weighting estimation of sample mean is established for negatively associated samples.     

Bayes Factor Consistency for One-way Random Effects Model

In this article, we consider Bayesian hypothesis testing for the balanced one-way random effects model. A special choice of the prior formulation for the ratio of variance components is shown to yield an explicit closed-form Bayes factor without integral representation. Furthermore, we study the consistency issue of the resulting Bayes factor under three asymptotic scenarios: either the number of units goes to infinity, the number of observations per unit goes to infinity, or both go to infinity. Finally, the behavior of the proposed approach is illustrated by simulation studies.     

中国技能偏态性技术变迁的实证检验:兼论大学教育溢价

本文利用中国2002-2010年地区面板数据,实施空间面板估计技术实证检验了我国技能偏态性技术进步的存在性。研究表明：我国现阶段技术呈现技能偏态特征,技术水平呈现东-中-西梯度发展格局;地区间的经济发展、要素投入以及人力资本水平呈现发散效应;相对于以往研究,本文规模报酬可变的总量生产函数设计可以更合理地逼近中国经济增长过程,空间相关性的诊断使我们能更好地评价中国不同地区、不同发展阶段是否存在技术异质性特征;最后考虑到现阶段大学生平均就业难的事实,提出应充分考虑到劳动力市场的多元分割特征,实现技能偏态技术与大学生供给有效对接的政策建议。     

中国省际GDP强影响性特征及其形成机制研究

本文采用最新前沿的宏观经济数据诊断和空间面板模型理论和方法,对我国30个省（西藏除外）1999-2011年的省际GDP强影响性特征进行了实证分析,在此基础上,进一步进行B-N分解深入研究了其形成机制。主要结论表明：我国省际GDP不仅空间关联,而且存在着显著的强影响性特征,每一年样本信息对于样本期内全部信息的影响程度和大小存在着差异。同时,我国省际GDP强影响性特征具有极其显著的形成机制,随机性成分是造成强影响性的主要根源,周期成分也产生较为重要的影响。以上结论对于我国省际GDP强影响性特征判断具有十分重要的政策含义,进一步对于我国政府熨平经济波动、实现宏观经济的平稳较快增长的政策制订和完善等具有十分重要的现实借鉴意义。     

Why do American Indians vote Democratic?

We examine the relationship between a relatively large population of American Indians in eastern Oklahoma and the slow pace of that region's partisan realignment. With a 2012 exit poll, we empirically examine whether American Indians’ cultural ties and their socio-economic characteristics affected their vote choices. Because of their greater poverty, American Indians are more economically progressive and vote more Democratic than their white counterparts.     

Conditional correlation in asset return and GARCH intensity model

In an asset return series, there is a conditional asymmetric dependence between current return and past volatility depending on the current return’s sign. To take into account the conditional asymmetry, we introduce new models for asset return dynamics in which frequencies of the up and down movements of asset price have conditionally independent Poisson distributions with stochastic intensities. The intensities are assumed to be stochastic recurrence equations of the GARCH type to capture the volatility clustering and the leverage effect. We provide an important linkage between our model and existing GARCH, explain how to apply maximum likelihood estimation to determine the parameters in the intensity model and show empirical results with the S&P 500 index return series.     

管窥英、汉语交际中的歧义现象

本文把交际过程中出现的歧义现象分为无意歧义和蓄意歧义。前者是语言结构矛盾的自然显露;后者是说话人对于语言结构矛盾的积极利用以达到特定的交际目的。这样的分类,能显示语言消极的一面和积极的一面,在交流中区别对待,定会得到事半功倍的效果。本文还从语音、词、句法、语感、情理诸方面论述英语和汉语歧义现象,说明其对交流的关键作用。     

中国历史小说研究的突破与创新--评《中国历史小说的艺术流变》

中国的历史小说发端于敦煌演史类变文 ,扬波于宋元讲史平话 ,至明清历史演义 ,则洪波涌起 ,逐渐汇聚成为中国小说史的一股巨流。对于这一股巨流 ,探其源 ,溯其流 ,弄清它在不同历史阶段的艺术特征及其演化动因 ,进而评述它在中国小说史上的地位 ,总结中国历史小说创作的民族特色 ,这可以说是历史小说研究的主要任务之一。可是由于历史小说“流品至杂 ,至宋元以至于清 ,作者如林。以体例言之 ,有演一代史事而近于断代为史者 ,有以一人一家事为主而近于外传别传及家人传者 ;有以一事为主而近于纪事本末者 ;亦有通演古今事与通史同者。其作者有…
