This study examines how the effect of CEO duality on firm performance is affected by two internal governance forces – namely other executives in the top management team and blockholding outside directors. Results based on a longitudinal dataset from the U.S. computer industry were consistent with my hypotheses. Specifically, I found that the effect of CEO duality was negative when the CEO had dominant power relative to other executives and when the board had a blockholding outside director, but was nonsignificant otherwise. This study enriches our understanding of the effect of CEO duality, and helps reinforce the call for the nonduality structure as the default choice and put the burden of proof on those who wish to justify otherwise on special grounds. 相似文献

罗尔斯的正义论不只是对传统正义观的继承,更是对其的创新和发展。它较为深刻地论述了个人与社会关系这一带有普遍意义的社会基本问题。分配正义是转型期中国社会遇到的核心问题,是诱发各种社会矛盾的根源之一。罗尔斯所提出的解决分配不正义的基本原则和设想,给我们勾画了一个自由又平等的社会愿景。其《正义论》可以说给我们提供了一个解决社会不正义的极其优化的解决方案。 相似文献

This tutorial focuses on how to produce reliable and generalizable data from random‐digit‐dialing (RDD) landline and cell phone surveys. The article notes that RDD response rates have declined and explores the impact of this pronounced decline. The tutorial addresses order, response mode, and many other biases, sample size, cooperation and response rates, weighting, and hybrid designs‐all using examples from risk analysis to illustrate the key points. The article ends with a brief review of the advantages and disadvantages of major Internet and paper surveys tools, and how these can be molded and sometimes combined in repeated, longitudinal, and other designs to answer questions about risk preferences and perceptions. 相似文献

“信息”一词在不同的语境中具有不同的含义。作为知识产权对象的信息不应是信息论意义上的信息,而应是控制论意义上的信息,即具有“同型结构+意义”双重结构。这有其法学上的规范意义。具备“源于人、有价值、法定性”条件的信息即可成为知识产权的对象。 相似文献

在大面阵数字航测相机的使用过程中,存在影像光照不均匀的问题.由于硬件设计很难达到预想的效果,在光照过于强烈的情况下,还会产生CCD过饱和的现象,通过增加遮光片可以解决这一问题,但全色波段的影像会产生黑斑.而通过马斯克匀光的方法去除中心的黑斑,提高影像的质量.并且将图像中心的反差增大,加大对比度,增大图像灰度的动态范围. 相似文献

We study the reliability estimates of the non-standard mixture of degenerate (degenerated at zero) and exponential distributions. The Uniformly Minimum Variance Unbiased Estimator (UMVUE) and Bayes estimator of the reliability for some selective prior when the mixing proportion is known and unknown are derived. The Bayes risk is computed for each Bayes estimator of the reliability. A simulated study is carried out to assess the performance of the estimators alongwith the true and Maximum Likelihood Estimate (MLE) of the reliability. An example from Vannman (1991) is also discussed at the end of the paper. 相似文献

口译是翻译活动中的一项极其具有挑战性的工作,对译员的要求也非常高。论文在阐述了口译中翻译笔记的必要性和重要性之后,主要探讨了在连续传译中译员对翻译笔记所应该掌握的尺度:即既要认识到笔记的重要性,记好笔记;又要认识到笔记只是辅助,在翻译过程中,更应该注意在激活图式结构的帮助下开发大脑对讲话内容的整体把握和理解记忆。只有这样,在笔记的帮助下,口译员才更加有可能做到在理解之后更加准确、全面地翻译。 相似文献

Although women influence nearly 85 percent of new car sales, their experience at automotive dealerships differs significantly from that of men. Not only are women subject to sexist and patronizing behavior from automotive personnel, but they also often wind up paying considerably more for a vehicle than a male customer. In the past two decades, the Internet has evolved as a significant source of automotive information and advice. While the majority of car advice websites offer guidance to the general public, a handful address the automotive concerns of the female driver. These sites are significant not only for the information they make accessible to female visitors, but for what women gain—as drivers, consumers, and political actors—by reading them. This paper examines four popular websites that cater specifically to the woman driver. Calling upon feminist epistemologies, it demonstrates how such online locations empower women to become more informed drivers and consumers through the accumulation and distribution of women's automotive knowledge. Not only does this automotive knowledge aid women as negotiators, but it also provides them with the tools necessary to radically transform the hostile auto dealership culture, ultimately benefiting all in the market for an automobile. 相似文献
