    高级管理人员激励是现代企业理论研究中的一个非常重要的问题,绩效激励则是高管激励问题中最为核心的问题之一。西方国家近20年来的理论研究与经济实践丰富了管理者的监督和激励,并带来了对高管人员绩效激励的提升。 但是,实证研究中同时也发现高管报酬业绩敏感性并不如代理理论预测的那么高,这一结果至今是个谜。代理理论是否能够解决现实中的委托代理关系,哪些因素弱化了报酬与业绩之间的关系。澄清这些问题,对高管激励具有非常重要指导意义。虽然,已有的研究成果在一定程度上都能解释部分的偏差,但是不同流派的出发点各异,导致研究结论零散化,甚至出现前后矛盾,对报酬业绩敏感性的变化缺乏系统性的理论解释,致使难于为实务界提...As for the research background of this paper, top management incentive is one of the key problems among modern firm theories.

    目的:研究大气细颗粒物(fine particulate; matter,PM_(2.5))对人支气管上皮细胞活性的影响及其炎性作用。方法:用PM_(2.5)采样器采集上海地区大气PM_(2.5)样本,扫; 描电镜观察PM_(2.5)形态特征。将人支气管上皮细胞BEAS-2B暴露于不同浓度(0,50,100,200,400,800; mug/mL)的PM_(2.5) 12,24,48 h,细胞活力检测试剂盒(cell counting kit-8,; CCK-8)法检测PM_(2.5)暴露对细胞活性的影响。实时定量PCR(quantitative real-time; PCR,qRT-PCR)检测细胞粒细胞-巨噬细胞集落刺激因子(granulocyte-macrophage colony stimulating; factor,GM-CSF)和TNF-alpha mRNA的表达,Western印迹检测; GM-CSF和TNF-alpha蛋白的表达。结果:扫描电镜观察发现,PM_(2.5)形态多样,大小不一,直径大多等于或小于2.5; mum。与同时间点未暴露组比较,各暴露组(50~800; mug/mL)细胞活性呈不同程度的下降,差异具有统计学意义(P<0.05)。与未暴露组比较,暴露于100,400或800 mug/mL; PM_(2.5) 24 h后,GM-CSF和TNF-alpha; mRNA和蛋白表达水平明显升高(P<0.05),且PM_(2.5)暴露浓度越高,GM-CSF和TNF-alpha的mRNA和蛋白升高水平越显著。; 结论:大气PM_(2.5)可引起人支气管上皮细胞的炎症反应,降低细胞活性,这可能与PM_(2.5)促发和加重支气管肺部炎性疾病有关。Objective: To investigate the effects of airborne fine particle on cell; viability and inflammation in human bronchial epithelial cells. Methods:; Atmospheric PM_(2.5) samples were collected by PM_(2.5) sampler.; PM_(2.5) morphology was observed by scanning electron microscope (SEM).; Human bronchial epithelial cells (BEAS- 2B) were treated with PM_(2.5); at different concentrations (0, 50, 100, 200, 400, 800 mug/mL) for 12,; 24 or 48 hours, and the cell activity were evaluated by cell counting; kit-8 (CCK-8). The mRNA expression levels of (granulocyte-macrophage; colony stimulating factor,GM-CSF) and TNF-alpha were detected by; quantitative real-time PCR (qRT-PCR). Western blot was used to detect; the protein expressions of GM-CSF and TNF-alpha. Results: According to; SEM, the shape of PM_(2.5) varied, and the diameter was different and; mostly equal to or less than 2.5 mum. CCK-8 assay showed that different; concentrations of PM_(2.5) exposure for 12 hours, 24 hours and 48 hours; resulted in loss of cell viability of BEAS-2B cells (P<0.05). Different; concentrations of PM_(2.5) increased the mRNA and protein expression of; GM-CSF and TNF-alpha, and the higher concentration of PM_(2.5) induced; higher expression, which have statistical significant difference between; the groups (P<0.05). Conclusion: Atmospheric PM_(2.5) can cause; inflammatory response in human bronchial epithelial cells. They can; reduce cell viability, which may be related to the PM_(2.5) trigger and; aggravation of bronchopulmonary inflammatory diseases

    截球策略是决定机器人足球队比赛能力的重要因素。由于信息噪音、命令执行误差、多异构类型和随机异构参数等因素的影响,单纯基于个体技术的截球决策并不一定可靠。首先采用数学解析方法建立截球个体技术模型,利用牛顿迭代法求解最快截球周期、截球点和基本命令队列;然后基于bP神经网络描述两个截球周期相比的截球成功概率;最后机器人基于自己和同伴的角色关系、截球成功概率和截球点所在球场区域进行协作截球决策。实验结果显示基于角色的协作截球效果明显改善。基于此策略的机器人足球队在比赛中取得不错的成绩。Interception strategy is an important factor for the competitive ability of robot soccer team.Due to the effect of the information noise,command implementation error,multi-heterogeneous types and random heterogeneous parameters,the interception strategy simply based on individual skill is not necessarily reliable.Firstly,mathematical analysis method is adopted to establish the interception individual skill model,and Newton iteration method is used to get the fastest interception cycle,interception point and the basic command queue.Then BP neural network is adopted to describe the interception success probability comparing two interception cycles.Finally the robot makes the interception decision collaboratively considering the allocation of roles,the interception success probability and the playfield interception point locates.The experiment results show the improvement of the rolebased collaboration interception.The robot soccer team with such strategy gets good results in the competitions.国家自然科学基金(No.60704042);航空科学基金(No.20080768004);厦门大学985二期信息创新平台项目---
