摘要写作与篇章图式的培养

语言的输入和输出是二语习得中经常讨论的话题。要使语言能够自然地习得,就必须给学习者提供大量的可理解性输入,并能把这些可理解性知识输入转化为有效的输出。在读写过程中,篇章图式是理解和生成文章的一个关键的因素,因此,要从篇章语法、语义和语用三个方面培养学生的篇章图式。我们可将阅读形式作为输入,摘要写作形式作为输出,从而有效地提高学生的读写水平。     

Estimation of parameters in incomplete data models defined by dynamical systems

Parametric incomplete data models defined by ordinary differential equations (ODEs) are widely used in biostatistics to describe biological processes accurately. Their parameters are estimated on approximate models, whose regression functions are evaluated by a numerical integration method. Accurate and efficient estimations of these parameters are critical issues. This paper proposes parameter estimation methods involving either a stochastic approximation EM algorithm (SAEM) in the maximum likelihood estimation, or a Gibbs sampler in the Bayesian approach. Both algorithms involve the simulation of non-observed data with conditional distributions using Hastings–Metropolis (H–M) algorithms. A modified H–M algorithm, including an original local linearization scheme to solve the ODEs, is proposed to reduce the computational time significantly. The convergence on the approximate model of all these algorithms is proved. The errors induced by the numerical solving method on the conditional distribution, the likelihood and the posterior distribution are bounded. The Bayesian and maximum likelihood estimation methods are illustrated on a simulated pharmacokinetic nonlinear mixed-effects model defined by an ODE. Simulation results illustrate the ability of these algorithms to provide accurate estimates.

Computation of the percentage points and the power for the two-sided Kolmogorov-Smirnov one sample test

Two recursive schemes are presented for the calculation of the probabilityP(g(x)≤S _n (x)≤h(x) for allx∈®), whereS _n is the empirical distribution function of a sample from a continuous distribution andh, g are continuous and isotone functions. The results are specialized for the calculation of the distribution and the corresponding percentage points of the test statistic of the two-sided Kolmogorov-Smirnov one sample test. The schemes allow the calculation of the power of the test too. Finally an extensive tabulation of percentage points for the Kolmogorov-Smirnov test is given.     

CHARACTERIZATION OF EFFICIENT SEQUENTIAL SCHEMES FOR POPULATION GROWTH MODELS1

For population growth models, which include standard processes like Poisson, birth, birth-death, immigration-death, simple epidemic and M/M/1 queue as particular cases, we obtain efficient sequential schemes and characterize all efficiently estimable functions of the parameters by first deriving a sequential version of the information inequality.     

国有股减持方案设计研究

为防止由于国有股减持导致流通股扩容,股市下跌,引起流通股股东集体抛股,进而引发金融危机的严重后果,在国有股减持时必须对流通股股东进行足额补偿。为维持股市的稳定,减持定价时采用“竞价配售”方案更加合理。为了使方案能顺利推进,应从国有股流通的组织制度建立、行业结构安排和公司治理结构的完善三方面创造国有股流通减持的基础条件。     

明清讽刺小说之流变及艺术图式

本文廓清了人们对传统讽刺小说的理论误区,并对明清讽刺小说的发展轨迹作了清晰的勾勒。在叙述的过程中,本文阐述了中国传统讽刺艺术对讽刺小说的浸淫与渗透,并从古代讽刺小说文体的演变中归纳出明清讽刺小说的艺术规律。本文还对明清讽刺小说的叙述模式与艺术图式作了简要的总结,并试图通过与西方讽刺艺术的比较研究抽绎出明清讽刺小说的核心价值。     

国际碳市场价格驱动力研究——以欧盟排放交易体系为例

探索碳市场价格驱动力是能源经济领域关注的焦点问题之一。基于欧盟排放交易体系（EU ETS）碳期货价格,综合运用结构性断点检验、协整技术和岭回归方法分析碳市场价格驱动因素和驱动模式。结果表明:2007年巴厘行动计划、2008年全球金融危机和2011年欧债危机,均对碳市场价格走势产生了显著影响,导致了碳市场价格发生结构性变化;碳市场价格与能源价格、工业生产、气温条件等因素间存在协整关系;自2009年10月以来,碳市场价格观测值低于均衡值,未来碳市场价格仍将倾向于贬值。
