The Effect of Family Control on Stakeholders Investment: A Study from Chinese Listed Companies

随着关于家族企业研究的不断深入，学术界逐渐积累了家族企业与社会责任的相关研究成果。研究成果表明，家族企业是家族参与企业而形成的复杂系统，家族作为特殊的社会组织在此扮演最终控制人的角色，对各相关利益者的投入可能产生重要的影响。那么，家族企业与非家族企业对于整体相关利益者的投入是否存在明显差异？目前，国内大部分的研究仅限于直接探讨家族控制与社会责任的相关性，未从相关利益者的角度进行深入剖析。从相关利益者的角度加以研究，不仅可以揭示不同相关利益者群体对于公司决策的相应影响，还能为公司进行社会责任投入的行为提供内在逻辑。如果进一步细分相关利益者，家族控制对于各相关利益主体投入是否有所偏好？这是本文试图...Family firm is a complex system with the family involvement. Family plays the role of the ultimate controller in enterprise organization resulting from its unique social characteristics. Thus, the family involvement may have an important impact for investment of each stakeholder. As for all stakeholders, is there a significant difference between family firm and nonfamily firm?

我国旅游上市公司多元化经营绩效分析

根据"多元化—效率—绩效"的研究思路,经过对2000-2009年沪深两市三种不同类型的旅游上市公司多元化经营绩效进行实证分析。发现饭店类上市公司的相关多元化和绩效有显著的正相关关系;资源类旅游上市公司的相关多元化和绩效有显著的正相关关系,但是这种正相关关系并不是通过效率联结的;综合类旅游上市公司的相关多元化和绩效呈不显著负偏相关,通过效率也和绩效不显著偏相关,但是两者效果叠加则显著负相关

A Study of De-noising Methods in Face Recognition System

人脸识别是近几年来非常受关注的研究课题之一,这一研究领域包括:图像处理、模式识别、计算机视觉、神经网络,心理学等多个交叉学科。人脸识别系统非常复杂,其中处理的对象都是人脸图像数据。从现实中获取的图像包含各种噪声信号,使图像数据和现实差距太大。为了快速有效的去除这些噪声信号,本文详细研究了各种去除噪声的方法和原理,通过试验以直观的方式研究几种去噪效果,指出各种方法的优缺点。提出了将小波去除噪声和特征提取相结合以及PCA在噪声去除和特征提取相结合的方法。Machine recognition of human face still and video im- ages is emerging an active research area including several disci- plines, such as: image processing, pattern recognition, computer vision, neural networks, psychology and so forth. The human face recognition system is complex which processes a large of image data. Obtained from reality environment, the images con- tain a lot of noise. In order to de- noise more effectively and quickly, several general de - noising methods and theories are carefully studied in the paper. Compared the methods through the experiences and got results, then, the advantage and disad- vantage of each method are pointed out. The novel methods are suggested, for example, combining wavelet de- noising with fea- ture extraction, combining de- noising with PCA.福建省自然基金(A0310005);; 国家留学回国人员基金资助(K13003

First-Principles Study of Effect of Strain on the Band Structure of ZnO Monolayer

采用基于密度泛函理论的第一性原理计算对单层znO薄膜能带结构的应变调控进行了研究.计算结果表明:沿着之字形方向的压缩应变和扶椅形方向的拉伸应变对薄膜带隙的调控都是线性的,而且带隙调控的范围最大;相反地,在沿着之字形方向的拉伸应变和扶椅形方向的压缩应变的调控下,带隙则呈现出非线性的变化.对于双轴应变的拉伸与压缩,带隙的变化都是非线性的.这种通过不同的应变加载方式来实现对带隙不同程度的调控,对znO薄膜在光学和催化等领域的应用具有重要的指导意义.The effect of strain on the band structure of the ZnO monolayer has been investigated by firstprinciples calculations based on density functional theory.The results reveal that the band structure of the ZnO monolayer presents different dependences on three types of strain.The band gap linearly and steeply varies under uniaxial zigzag compressive strain and armchair tensile strain, while it shows nonlinear dependence on the other types of strain.Therefore, uniaxial zigzag compressive strain and armchair tensile strain should be the most effective to tune the band gap.This work has significant implications for application of strain to tune the optical and catalytic properties of ZnO nanofilms.国家自然科学基金(10702056;11204252); 四川省教育厅(12ZA072)资助项目~
