上市国企高管薪酬业绩敏感性结构化解析
Research on Executive Pay Performance Sensitivity Structure of Chinese State-Owned Listed Companies
 [PDF]

Finance (FIN) , 2016, DOI: 10.12677/FIN.2016.62008
Abstract:
本文以2006~2013年1001家国有上市公司为样本,通过动态面板数据构建多元回归模型对国有企业薪酬业绩敏感性结构化差异进行实证检验,比较了中央控股国有企业和地方控股国有企业在薪酬业绩上的不同表现,及国企高管业绩敏感性在行业上的差异。研究发现:(1) 我国国有上市公司高管薪酬与业绩存在相关性,但其薪酬业绩敏感性显著低于非国有上市公司;(2) 国有上市公司中,央企高管薪酬业绩敏感性显著低于地方国企;(3) 金融行业国有上市公司管理层的薪酬业绩敏感性显著低于其他行业。实证结果有助于明确未来国企薪酬改革政策的指向性,本文据此提出了多层次治理建议,对国企薪酬制度的进一步完善具有参考意义。
In this paper, the sample of the models includes 2561 China’s state-owned listed companies from 2006 to 2013 (including the 1001 state-owned listed companies). By constructing the panel data regression models, this research compares the difference between the executive pay performance sensitivity of central state-owned enterprise and that of local state-owned enterprises, as well as the difference of executive pay performance sensitivity of state-owned financial institutions and state-owned non-financial institutions. The study result shows that: (1) there is a significant cor-relation between the executive pay and company performance of China’s state-owned listed com-panies, but the executive PPS of state-owned listed companies is evidently lower than that of non- state-owned listed companies. (2) Executive PPS of central state-owned companies was significantly lower than that of local state-owned companies. (3) Executive pay performance sensitivity of state-owned financial enterprises was significantly lower than that of state-owned non-financial enterprises. When it comes to policy on executive compensation regulation of state-owned enter-prises, items should also be more targeted. This study offers reference for further optimization for executive performance appraisal system in state-owned companies.

How to parse and inquire the ontology is the key technique for the semantic web to achieve intelligent semantic retrieval. The paper gives a deeply research of the ontology parse and inquire method based on Jena, and be used in the compiler principle course ontology.
食物图像的色彩增强算法研究与实现
Research and Implementation of Color Enhancement Algorithm in Food Image

Abstract:
针对拍摄的食物照片的后处理需求,现有方法不适用的问题,提出了一种食物图像的色彩增强算法。该算法采用HSI和HSV两种颜色空间联合处理,利用设计的饱和度矫正曲线和符合食物色彩特征的色调参数曲线做加权矫正,以及设计的亮度矫正曲线处理。该算法针对于食物图像的色彩增强,弥补了食物色彩增强算法方面的空缺。实验结果表明,该方法可以大大提高食物图像的主客观质量。本文提出的食物图像的色彩增强算法,针对食物色彩特征进行设计,采用两种颜色空间联合处理,得到适用于食物图像的增强效果。
Because the conventional methods are not suitable for the post-processing of food image, we pro-pose a color enhancement algorithm in food image. The algorithm is processed in HSI and HSV color space, using designed correction curve of color saturation with parameter curve of hue, which corresponds to the feature of food image, and uses designed correction curve of brightness. This algorithm is targeted at color enhancement of food image and fills the blank of color enhancement algorithms in food image. Experimental results show that the algorithm can greatly improve the subjective and objective quality of food image. The color enhancement algorithm in food image that we proposed is designed with the characteristics of food image, combined with the use of two color spaces, to get an enhancement result which is suitable for food image.
煤矿汽运智能定量装车系统

煤炭工程 , 2012,
Abstract: 由于放煤过程均为人为控制,装车亏载和过载现象严重,且速度慢、劳动强度大、劳动环境差,不但给企业管理带来了很大的困难,而且给企业带来了巨大的经济损失。因此,有必要对此过程进行全自动定量控制,在操作室设置监控和报警装置,对整个装车过程、各给煤机的运行状态及其他故障和意外情况进行实时监控,提高装车精度和速度,为煤矿企业减少不必要的经济损失。

技术创新对产业演进的影响――基于模块化系统的产品创新阶段分析

科技进步与对策 , 2008,
Abstract: 在以模块化为特征的产业中,产品创新引导产业演进,创新影响企业的进入与退出。在产品创新中,对在位者的分析应考虑代际范围经济和资源转换成本。新厂商可采取产品创新、模仿创新以及利用分裂技术等方式进入。创新技能、模块化程度、沉没成本和市场环境等将影响新厂商的进入。创新竞争的结果,使核心模块市场结构趋于竞争性垄断,一般模块和系统的装配市场则日趋竞争,企业间网络得以大力发展。以模块化为特征的产业资源转换成本代际范围经济

冠心病血脂蛋白相关磷脂酶a2水平与冠脉病变的相关性研究

天津医药 , 2011,
Abstract: ?目的:探讨冠心病患者血脂蛋白相关磷脂酶a2(lp-pla2)水平与冠状动脉病变程度及斑块稳定性的关系。方法:将299例拟诊冠心病患者根据冠脉造影结果分为冠心病组(232例)和对照组(67例),冠心病患者再根据临床类型分为ami组(46例)、uap组(114例)、sap组(72例)并计算冠脉gensini积分,检测其血浆lp-pla2水平及总胆固醇(tc)、三酰甘油(tg)、低密度脂蛋白胆固醇(ldl-c)、高密度脂蛋白胆固醇(hdl-c)、脂蛋白a[lp(a)]、纤维蛋白原(fib)和c反应蛋白(crp)水平并进行比较,分析lp-pla2与冠心病及gensini积分的关系。结果:冠心病组血浆lp-pla2水平高于对照组(p<0.01);ami组和uap组患者lp-pla2水平高于sap组(p<0.05),ami组和uap组之间差异无统计学意义;lp-pla2水平与ldl-c、crp、gensini积分呈正相关,lp-pla2、高血压、ldl-c和lp-a是冠心病的独立危险因素,hdl-c为保护因素,gensini积分受年龄、lp-pla2、hdl-c和ldl-c的影响。结论:血lp-pla2升高是冠心病的独立危险因素之一,lp-pla2水平与冠脉病变严重程度及动脉粥样硬化斑块的稳定性相关。
