What Plato Knew About Enron

This paper applies Plato’s cave allegory to Enron’s success and downfall. Plato’s famous tale of cave dwellers illustrates the different levels of truth and understanding. These levels include images, the sources of images, and the ultimate reality behind both. The paper first describes these levels of perception as they apply to Plato’s cave dwellers and then provides a brief history of the rise of Enron. Then we apply Plato’s levels of understanding to Enron, showing how the company created its image and presented information to support that image, and how the public eventually emerged from the cave to realize the truth about Enron’s actual accounting practices and financial state, which led to the corporation’s downfall. We find Plato’s allegory both useful in analyzing the relationship between Enron and the public and instructive about the power and moral responsibility of Enron’s executives.

菲涅耳非相干全息术3D全息成像探讨

全息成像提供了一种从单一观察点捕捉具有完整三维信息画面的可靠、快捷的方法。本文回顾了近期提出的单通道菲涅耳数字全息光学系统,该系统能获得由非相干光照射的三维实物体的全息图。在这一静态全息技术中,由三维物体反射或发射光,在通过空间光调制器（SLM）后,用数码相机记录。SLM被用作单通道非相干干涉仪的分束器,使来自物体上各点的球面波被分成两束具有不同曲率半径的球面波。所有球面波干涉结果的非相干总和,即可生成被观测物体的三维菲涅耳全息图。在计算机中可再现该全息图,使其三维特征得以呈现。     

PI背景下的TDI结构方程模型

态度理论为地区形象(PI)和旅游目的地形象(TDI)的联合研究提供了一个平台。本文构建了一个理论上的地区形象背景下的旅游目的地形象结构方程模型。模型是一个具有因果关系的结构方程模型,包括8个潜变量和28个观测变量。以徐州为例,在运用SPSS15.0软件对数据进行信度检验的基础上,利用LISREL8.70软件对模型进行了验证性因子分析和路径分析。研究发现:(1)结构模型中各潜变量之间的路径与假定基本符合,模型的整体拟合性能良好;(2)旅游资源认知和旅游服务认知会对旅游意愿产生作用,这符合我们的传统理念;(3)地区特征和居民素质对旅游服务感知、目的地评价和旅游意愿三者均有效应,而地区竞争力和居民竞争力仅对旅游服务感知产生影响。     

智能监控中图像预处理与去噪方法

在序列图像中进行图像预处理。在传统图像差分的基础上，提出了将数学形态学的膨胀腐蚀算子用于运动物体的连接填充；在此基础上进行去噪，得到运动物体。     

边缘检测应用问题研究

工业CT是一种先进的无损检测技术,近年来,从定性向定量测量发展是其的一个重要研究方向,且已取得了很大进展。然而,目前国内外工业CT图像测量大都还依赖于手工进行,这样不仅在可重复性和精确度上存在着很大问题,而且越来越无法适应于大批量的图像处理工作。因此,笔者针对手工测量存在的某些问题,结合工业CT图像的自身特点提出了一种基于边缘提取的自动测量方法。     

Sponsorship effects on brand image: The role of exposure and activity involvement

Sponsorships capture a significant proportion of marketing budgets. In firm evaluations of the effectiveness of sponsorship engagements, image improvements represent the most important company objective. This study develops and tests a framework for explaining how exposure and activity involvement moderate the effects of event image, event–sponsor fit, and event commercialization on sponsor image. Using empirical data collected at a large sporting event with multiple sponsors, the authors show that increased sponsorship exposure reduces sponsor image if respondents perceive a low fit between the event and sponsor or high levels of event commercialization. Involvement in the sponsored activity improves the sponsor's image, in that the effect of event commercialization is positive for highly involved persons. This paper concludes with some reasons for the findings, implications for the choice and design of sponsorships, and further areas for research.     

Google Earth在成都市功能分区研究中的应用

在历经了20余年的改革发展后,成都市在基础设施建设、产业结构调整和生态环境保护等方面都取得了长足的进步,在政治经济文化发展的同时,城市的用地规模日益扩大,城市功能分区日趋复杂,人地矛盾、功能与形态分区矛盾日渐凸现,城市功能分区已经成为制约城市发展的重要因素之一.为此开展成都市功能分区的研究也愈加重要,利用Google Earth软件提供的在线浏览的高分辨率遥感图像,结合其特有的空间分析和查询功能,探讨成都市的功能区的分区及成因,并对城市功能分区的发展趋势做出预测.     

To Trust or Not to Trust? Consumer Responses to Cause-Related Marketing

Abstract

The purpose of this study is to understand if company trustworthiness and the type of cause-related marketing (CRM) campaigns (strategic vs. tactical) affect purchase intention and company image of a yogurt producer, under the control of socially responsible consumer behavior, general trust, income, attitude toward the CRM campaign, and initial company image. The study applies a quantitative (experimentation) research to test the proposed model. MANCOVA was applied with data obtained from 600 respondents who were selected by a two-stage cluster sampling method. The research model is partially supported. Company trustworthiness and CRM type are found to affect only company image and without any interaction effect. Being a highly trustworthy company applying a CRM campaign has more positive influence on company image than a less trustworthy one. Additionally, a strategic CRM campaign creates more positive influence on company image than a tactical one. The findings are further deliberated with the managers of the two selected companies with focus group discussions.
