The challenge of inferior Q waves

The presence of unexpected Q waves in an applicant's electrocardiogram poses a diagnostic dilemma for the medical director. On the one hand, the Q waves may be the remnants of a previously unsuspected "silent" myocardial infarction. Conversely, unexpected Q waves may represent a normal or positional variant, or an important noncoronary type of heart disease. This case study illustrates some of the pitfalls in interpreting applicants' electrocardiograms containing Q waves in the inferior leads.     

Richard Abel. Americanizing the Movies and "Movie-Mad" Audiences, 1910-1914

Richard Abel argues that in the period from 1910, when the motionpicture "revolution" succeeded and the American film marketwas emancipated from French domination, to 1914, when foreignfilms were nearly eliminated from the U.S. market, the Americanfilm industry was characterized by widespread experimentationand innovation, especially in the areas of promotion practices,distribution strategies, content refinement, and audience development.Six chapters of Abel's Americanizing the Movies bring to theforeground the battle of

基于VR技术的油井压裂仿真系统的研制

目前对油井压裂技术培训主要是通过文字、图片等资料。油井压裂属于地下工作,员工无法真实地感受到地下工具的工作状况和状态。该系统采用虚拟现实技术将管柱压裂的整个过程以及压裂过程中各种工具的受力和变形情况进行计算机模拟,从而大大增加员工学习的兴趣和效率,进而提高管柱压裂过程的管理水平和实践水平。

Simultaneous versus sequential information processing

Subjects update prior information simultaneously versus sequentially. The mean prediction is remarkably close to the correct Bayesian estimate with simultaneous information, but differs significantly conditional on whether good news precedes bad news or vice versa.     

Who votes for public environmental goods in California?: Evidence from a spatial analysis of voting for environmental ballot measures

Voting referenda provide direct evidence of the demand for public goods. A number of previous studies have used referenda to analyze the support for public environmental goods. These studies have used aggregate data from large jurisdictional units (usually counties) and summary income measures such as the mean or median, and have usually found that higher income areas offer greater support for environmental propositions. We examine environmental referenda voting in California using census block group data, spatial dependence controls, and detailed income distribution data. We find that household income has a negative marginal effect on environmental referenda voting for most of the income range when using census block data. In addition, controls for spatial dependence significantly reduce the magnitude of most coefficients. This suggests that OLS estimates of referenda determinants are biased. We also show that county level data may be subject to severe aggregation bias and might not be appropriate for referenda studies.

股权分置改革对价方案解析

本文从经济学基本原理出发,重申股权分王改革的最终目的是从根本上解决我国股市存在的资源配王效率低下和主体缺失的制度性缺陷问题,认为合理对价支付比例的确定应该遵循政策中性原理,并根据套利理论推导出市场均衡条件下的对价公式,对46家试点公司和进入全面股改后推出的前两批72家公司的对价方案进行剖析,认为部分公司对价支付比例存在不合理的原因是方案确定的原则存在片面性。     

制造企业组织柔性、动态服务创新能力与服务创新绩效

随着制造业服务化转型的逐渐深入,服务成为价值交换的核心要素,企业研发工作的重心从产品创新延伸到服务创新。在服务创新背景下,市场需求、关键资源和创新模式的内涵都发生了根本改变,促使企业不断提高自身适应性以应对挑战。然而,目前关于该主题的研究尚不充分。分析并验证了制造企业组织柔性对动态服务创新能力和服务创新绩效的影响。从支撑服务创新的角度出发,将组织柔性划分为组织文化柔性、组织结构柔性和人力资源柔性,分析了组织柔性通过增强企业动态服务创新能力（服务需求感知能力、服务方案开发能力和服务系统重构能力）提升服务创新绩效的作用机制,构建了反映上述概念之间关系的理论模型。以组织市场（B2B）作为研究背景,面向制造企业管理者收集数据,通过实证分析对理论模型进行检验。研究结果表明：组织柔性对服务创新绩效具有积极影响,动态服务创新能力和市场动态性分别在二者间关系中起中介作用和调节作用。最后,就企业如何提高组织柔性,增强动态服务创新能力,进而改善服务创新绩效提出若干建议和对策。
