    随着老龄化进程的加快,我国老年人口数量已于2014年底突破两亿,并以年均3.4%的速度递增。我国老年人的养老问题日益严峻,传统的家庭养老模式已无法适应日益增长的养老需求。目前,全国各地养老服务的供需矛盾依旧非常严重,养老机构在档次上分布不均,市场需求量最大的中档养老机构各地普遍供给不足。为此,近年来,国家加大了对养老服务产业的政策和资金扶持,并鼓励和开放民间资本参与养老服务业发展,为社会力量投资兴办养老服务机构提供了有利保障。 厦门老年人口处于快速增长期,养老服务需求市场巨大,但养老服务业的发展整体上仍不成熟,养老机构少、床位供应不足、服务内容单一、管理不规范、人员不专业等问题制约着厦门养老...The elderly population has reached two hundred million at the end of 2014 in our country as the speeding up of aging, and is increasing at average rate of 3.4% per year.

    股票市场中的知情交易水平及其性质是投资者非常关心的话题。知情交易 水平不仅影响投资者所面临的逆向选择风险,而且也会影响到市场的有效性。 知情交易率作为信息不对称的指标,在研究资产价格的形成、市场的波动率方 面有着不可替代的作用。信息定性的性质和无形的形式决定了估计这个变量需 要特别的方式,因此建立一种模型来估计知情交易率使其更加真实地模拟信息 不对称的性质显得日益重要。 本文将不知情交易者的交易行为引入到Tayetal.(2009)模型中来估计知情交 易概率;并且发现知情交易者的交易密度下降,知情交易率下降。同时发现, 当久期的变化在整个样本区间中变化比较平缓时,各消息状态存在...The level and feature of the probability of informed trading(PIN) are of great concern to investors in the stock market. Informed trading not only affects the adverse selection that the investors face with, but also the market efficiency. As a proxy of asymmetry information, PIN plays an important role in the evolution of the price as well as the variation of the volatility.

    Discussing Some Questions on Conceptual Framwork of Accounting Standards

    Get PDF
    本文认为,一方面会计准则的制定需要会计理论进行指导(这一会计理论主要是指财务会计概念框架);另一方面,我国新修订的《企业会计准则——基本准则》还不能称为财务会计概念框架,由此得出我国需要构建会计准则理论结构。第一章:建立会计准则理论结构的重要性。首先界定了会计理论的涵义及研究意义,指出会计理论对会计实践活动具有指导作用,会计准则制定这一实践活动同样需要会计理论的指导,西方会计准则制定史也证明了这一观点。第二章:会计准则理论结构的发展历程。本章首先简单介绍了会计准则理论的分类,然后从会计学术界和准则制定机构两个方向回顾了美国会计准则理论结构的发展史,并对其进行了简单的评析。第三章:西方财务会计概...Since the announcement of America statements of Financial Accounting Concepts in 1978, the research on Conceptual Framework (CF) has been the core of financial accounting theory. Some countries and international organizations are learning from it in succession. It is broadly accepted that the CF with strict and consistent logic has been considered as the theoretic base of establishing accounting s...学位:管理学硕士院系专业:管理学院会计系_会计学学号:20031103

    此研究结果表明这类激光器的小信号增益分布与气体流速有关。在静止气体或非常慢速流动下,小信号增益分布取决于气体温度的分布;而当气体流速增加到一定数值后,小信号增益分布则取决于气体速度在放电管内的分布The distribution of small signal gain in a planar,large area discharge,RF excited CO 2 laser was measured and analyzed.The results show that the small signal gain distribution of such laser is closely related to gas flow rate.Under static or very slow gas flow,small signal gain distribution depends on temperature distribution in the discharge channel.Whereas when the flow rate increases to a higher level,small signal gain distribution depends on gas velocity distribution

    大跨度斜拉桥Benchmark问题的振动控制研究是当前国际结构控制研讨会的重要议题之一。以美国Bill Emerson Memorial斜拉桥第二阶段Benchmark模型为研究对象,在非线性随机动力学与控制的拟哈密顿理论体系框架下,运用基于随机平均法和随机动态规划原理的非线性随机最优(NSO)控制策略,对地震作用下的Benchmark模型进行MATLAB仿真分析。将最优控制力和性能评价指标与线性二次型Gauss(LQG)控制的计算结果进行对比,得出非线性随机最优控制策略能够更加有效地抑制斜拉桥的地震响应,提高结构的动力稳定性和抗震能力,具有更好的控制效果,对实际桥梁工程的振动控制具有较强的指导意义和适用价值。Investigation of vibration control for benchmark problems on large-span,cable-stayed bridge is one of the most important research topics in the current International Symposium on Structural Control. This paper studied secondstage benchmark problems on the Bill Emerson Memorial cable-stayed bridge. In terms of Hamiltonian theory for nonlinear stochastic dynamics and control, the benchmark model under seismic excitations was investigated using MATLAB simulation analysis,based on the stochastic averaging method and stochastic dynamic-programming principle. Comparison of analysis results for optimal forces and performance-evaluation indices between the nonlinear stochastic optimal( NSO)control strategy and the linear quadratic Gaussian( LQG) control strategy revealed that the former control strategy mitigates the seismic response of the cable-stayed bridge more effectively than the latter,thereby enhancing structural dynamic stability and earthquake resistance. In conclusion,the NSO control strategy demonstrates better control effect and presents instructive references and practical significance for vibration control of bridge-engineering applications.福建省青年人才项目(2008F3100
