股票流动性与股价崩盘风险:公司治理和短期行为视角
流动性究竟能够稳定市场还是给市场带来危机?文章从股价崩盘风险的视角,探讨了股票流动性与股价崩盘风险的关系,研究发现:股票流动性促进了股价崩盘风险,因而并没有起到稳定市场的作用。随后,从\"治理理论\"和\"短期行为理论\"两个角度对影响机制进行探讨,研究发现:在二职合一、独立董事比例较低、短期机构投资者持股比例较高时,股票流动性对股价崩盘风险的正向影响更加显著。研究结论既丰富了股票流动性及股价崩盘风险的相关文献,也给管理层及上市公司从微观视角认识股价崩盘风险提供新思路及借鉴。国家自然科学基金重点项目“制度环境、公司财务政策选择和动态演化研究”(71232004);;福建省中青年教师教育科研项目“基于企业创新视角的股权结构优化对策研究”(JAS170348);;厦门理工学院社会科学研究项目“产品市场竞争的治理效应实证研究——大股东掏空视角”(YSK13013R
Application of EaR in Risk Management of Petroleum Market in China
石油是具有不可再生性和稀缺性的资源,是关系着国民经济振兴和国家经济安全的战略物资。近年来,随着我国经济的快速增长,国内石油产量已很难满足日益增长的石油需求,我国石油的进口依存度大幅提高,2003年我国的石油净进口量首次超过日本,成为仅次于美国的世界第二大石油净进口国。与此同时,国际石油价格近年来波动频繁,尤其是在刚刚过去的2008年,国际油价一度疯涨至历史最高水平,随后又跌至近五年新低。因此,深入研究石油市场的风险管理,对于企业规避石油价格风险,保证我国经济持续健康、快速、稳定增长具有重要的理论和现实意义。 本文首次将EaR风险管理理论引入石油市场,并以中国石油天然气股份有百万元限公司为例进...Petroleum, which is a non-renewable and scarce resource, is very important to the development and security of the national economy. As the economy grew rapidly in China in recent years, the domestic oil production can’t meet the growing oil demand any more and the oil dependency on other countries increased substantially. China became the second largest oil net import country from 2003 after it su...学位:经济学硕士院系专业:经济学院计划统计系_统计学学号:1542006115082

A Translation of Mo Yan's "Three Essays about Eating" and Its Strategies: The Textual Perspective
作家莫言于2012年荣获诺贝尔文学奖,成为诺贝尔文学奖第一位中国籍作家。莫言散文《吃事三篇》由《吃的耻辱》、《吃相凶恶》、《忘不了吃》三篇文章构成,一并收录于莫言散文集《会唱歌的墙》中。《吃事三篇》是莫言对吃的记忆,他在其中毫不忌讳地叙述了记忆中经历的种种关于吃的“丑事”,并采用虚构夸大的写法将吃的经历写得触目惊心。其语言直白、简单、自嘲调侃又不失辛辣讽刺。 本论文在对《吃事三篇》进行英译的基础上,从语篇翻译的角度对译文进行了翻译策略的分析。语篇翻译把翻译看成是一个自上而下的过程。其研究对象不仅包括语言系统和言内因素,也包括言外因素,能较为全面地研究并指导翻译过程。论文从语篇的连贯性、语篇的...The Chinese author Mo Yan has been awarded the 2012 Nobel Prize for literature, making him the first ever Chinese literature Nobel laureate. The "Three Essays about Eating", i.e. "Eating Invites Humiliation", "Piggish Eating Manners" and "All about Eating" are included in his collection of essays A Wall That Can Sing. In the three essays he incisively and vividly depicts his hideous eating experie...学位:翻译硕士院系专业:外文学院_翻译硕士学号:1202011115259
Electronic integrated marketing communication model construction and case study based on AISAS pattern
网络媒体的发展,特别是web2.0的运用和发展,对人们的信息获取模式和消费模式产生了巨大的影响。在网络时代,大众对信息消费的行为模式发生了明显的变化,目前消费者的信息行为模式正从传统的AIDMA法则(Attention注意Interest兴趣Desire欲望Memory记忆Action行动)逐渐向具有鲜明网络特质的AISAS模式(Attention注意Interest兴趣Search搜索Action行动Share分享)转变。 在AISAS模式中,受众在引起注意、产生兴趣之后,接着执行的就是搜索。在网络时代,企业的信息相对公开,而且网络平台为品牌消费者进行品牌体验分享提供了一个良好的渠道。因为...The development of cyber media, especially the application and development of web2.0, has made the great effect on people's information acquisition pattern and consumption pattern. During the computer age, the behavior pattern of masses’ information consumption changed a lot, currently, consumer’s information behavior pattern is gradually transforming from the traditional AIDMA rule (Attention, In...学位:文学硕士院系专业:新闻传播学院广告学系_传播学学号:1052006115024
最大后验贝叶斯估算法制定华法林个体化给药案例探讨
目的:探讨临床药师在华法林个体化给药方案制定及实施监护过程中发挥的作用。方法:临床药师采用最大后验贝叶斯估算法制定华法林患者的给药方案,并对方案实施过程进行了监护,及时识别了药物相互作用导致的INR升高,避免了出血不良反应的发生,同时也及时发现了患者漏服药物导致的国际标准化比值(INR)降低,避免了患者再次发生血栓。结果:最大后验贝叶斯估算法可以较好地估算和指导临床用药,对于个体化给药方案具有极大的参考价值。结论:根据基因检测结果选择合适的算法为华法林患者制定了个体化给药方案后,临床药师还需要对整个给药方案实施过程提供全程化的监护,以便及时发现疾病、药物相互作用、依从性不佳等导致的INR异常波动,从而提供抗凝效果,减少出血和栓塞等不良反应。福建省科技计划引导性项目(编号:2015Y0020
Transition to turbulence in the floating half zone convection
The transition process to turbulence is studied experimentally in thermocapillary convection of floating half zone. The onset of temperature oscillations in the liquid bridge of floating half zone and further transitions of the temporal convective behaviour are detected by temperature measurements in the liquid bridge. The fast Fourier transform (FFT) reveals the frequency and amplitude characteristics of the flow transition. The experimental results indicate the existence of a sequence of period-doubling bifurcations that culminates in turbulence. The measured Feigenbaum numbers are δ2 = 4.69 and δ4 = 4.6. Both results can be compared with the theoretical asymptotic value δ = 4.669
Whether therapeutic drug monitoring is necessary for linezolid?
利奈唑胺非肝药酶代谢,约35%以原型经肾排泄,说明书提示其浓度受其他药物影响轻微,肾功能不全患者无需调整剂量,但临床研究表明肾功能不全患者利奈唑胺所致血小板减少症或贫血发生率增高与利奈唑胺高暴露相关,且利奈唑胺与某些药物存在的相互作用可显著影响其血药浓度、利奈唑胺的血药浓度在危重症患者中个体差异大,应进行血药浓度监测。Linezolid is not metabolized by CYP450 s and only approximately 35% of the prototype was excreted via the kidney, and its label suggests that its concentration is affected by other drugs slightly and no dose adjustment is recommended to patients with renal impairment. Nevertheless, clinic studies showed that the development of linezolid- induced thrombocytopenia and anemia was related to the high linezolid exposure in patients with impaired renal function, and the interaction between linezolid and other drugs may significantly affect its concentration. Considering these factors and the significant variability of linezolid concentration in critically ill patients, the therapeutic drug monitoring is necessary for linezolid to ensure its efficiency and safety
