中外上市公司独立董事机制之比较——从功能定位及权责的角度

独立董事制度产生后对美国公司治理起到了很大作用，并在其他国家迅速推广发展。该制度的引入本是我国上市公司解决内部人控制、一股独大问题的有利契机，但由于各种原因，独立董事在上市公司大股东侵害中小股东利益时未能发挥其应有的效用。文章通过对比研究我国与英美国家在独立董事功能定位、职权和责任上的不同之处，对完善我国独立董事机制提出一些建议。     

功能语境视域的《论语》歧义句语内翻译模式研究

语内翻译是典籍翻译过程中一个重要步骤,其对典籍歧义句的处理直接影响最终的翻译质量。在功能语境理论框架内,采用宏观功能语境分析和自下而上的具体分析相结合的方法,以《论语·学而篇》第8章“学则不固”的“固”字为例,对《论语》歧义句语内翻译进行研究,探讨可操作的翻译模式。研究发现在歧义句语内翻译过程中进行语境还原,有助消除词汇歧义;研究认为“学则不固”的“固”字应作“固陋”解译。      

Uncertainty Analysis for Functional Computer Output: A Simulation Study in Inverse Problems

Computer models with functional output are omnipresent throughout science and engineering. Most often the computer model is treated as a black-box and information about the underlying mathematical model is not exploited in statistical analyses. Consequently, general-purpose bases such as wavelets are typically used to describe the main characteristics of the functional output. In this article we advocate for using information about the underlying mathematical model in order to choose a better basis for the functional output. To validate this choice, a simulation study is presented in the context of uncertainty analysis for a computer model from inverse Sturm-Liouville problems.     

Conditional VAR and Expected Shortfall: A New Functional Approach

We estimate two well-known risk measures, the value-at-risk (VAR) and the expected shortfall, conditionally to a functional variable (i.e., a random variable valued in some semi(pseudo)-metric space). We use nonparametric kernel estimation for constructing estimators of these quantities, under general dependence conditions. Theoretical properties are stated whereas practical aspects are illustrated on simulated data: nonlinear functional and GARCH(1,1) models. Some ideas on bandwidth selection using bootstrap are introduced. Finally, an empirical example is given through data of the S&P 500 time series.     

翻译转喻的理据:从现象到人类认知

转喻机制具有普遍性,也存在于翻译过程中。在回顾前人研究的基础上,对翻译转喻现象进行了基本的分类,并从范畴化和认知语法角度分别对存在于词汇和句子层面的翻译转喻现象进行了分析。翻译转喻涉及音、形、意三个方面,研究发现：1）其主要实现途径包括整体代部分、部分代整体以及部分代部分;2）翻译转喻依托范畴化结构,尤其是当两种文化存在通用图式的情况下,翻译转喻就是对原语范畴之外其他级别范畴或同一级别其他范畴成员的凸显及在译语中的映射;3）增译、减译、转换等技巧是翻译转喻思维的具体方法论,其使用会导致译语概念结构出现不同程度的调整。研究成果对认知语言学、翻译学研究具有一定的启示意义。     

Inferences for a Partially Varying Coefficient Model With Endogenous Regressors

In this article, we propose a new class of semiparametric instrumental variable models with partially varying coefficients, in which the structural function has a partially linear form and the impact of endogenous structural variables can vary over different levels of some exogenous variables. We propose a three-step estimation procedure to estimate both functional and constant coefficients. The consistency and asymptotic normality of these proposed estimators are established. Moreover, a generalized F-test is developed to test whether the functional coefficients are of particular parametric forms with some underlying economic intuitions, and furthermore, the limiting distribution of the proposed generalized F-test statistic under the null hypothesis is established. Finally, we illustrate the finite sample performance of our approach with simulations and two real data examples in economics.     

Functional and emotional traits of corporate social media message strategies: Behavioral insights from S&P 500 Facebook data

Drawing from literature regarding public engagement, the Elaboration Likelihood Model (ELM), computer-mediated communication research, and emotion psychology, this study examines the effects of companies’ social media communication strategies on public engagement behaviors as indexed by post likes, shares, and comments. Specifically, it investigates how corporate Facebook posts’ functional traits (functional interactivity and vividness) and emotional traits (emotion presence, valence, and strength) impact public engagement online. Through data mining and computer-assisted sentiment analysis of 33,379 posts from 106 Standard & Poor 500 companies’ Facebook accounts, this study finds a negative effect of functional interactivity but a positive effect of vividness on engagement. It also shows that emotional traits overall yield stronger public engagement outcomes. Two-way interactions between emotional and functional features are also detected. Theoretical and practical implications are discussed.     

角色参照语法的分析框架及其解释能力探析

角色参照语法是20世纪70年代以来发展起来的一种结构功能语法。论文尝试评述其主要的语法分析框架,并以英语和汉语为例探究其对不同语言的解释能力。角色参照语法成功地将语篇、语用因素融入到句法结构的分析之中,因此,它不仅能够较好地解释英语等形合语言的结构特征,也适用于具有意合特征的汉语等语言的结构分析。角色参照语法比传统的形式语法具有更大的灵活性和适用性。     

Uniform in bandwidth consistency for various kernel estimators involving functional data

The paper investigates various nonparametric models including regression, conditional distribution, conditional density and conditional hazard function, when the covariates are infinite dimensional. The main contribution is to prove uniform in bandwidth asymptotic results for kernel estimators of these functional operators. Then, the application issues, involving data-driven bandwidth selection, are discussed.
