价值管理:会计的一场革命

由于会计环境的巨大变化 ,现有会计体系呈现出固有的缺陷 ,会计变革已迫在眉睫。传统会计是一个经济信息系统的观点 ,已束缚了会计学科的发展。价值管理已成为当今企业管理的核心内容。从价值管理角度诠释会计新概念 ,可以克服现有会计体系的固有缺陷 ,极大地扩展了会计学科的视野。新会计体系将包括价值信息管理(财务会计、管理会计和审计等 )、价值活动管理 (财务管理、内部控制制度等 )

On the Convergence of the Monte Carlo Maximum Likelihood Method for Latent Variable Models

While much used in practice, latent variable models raise challenging estimation problems due to the intractability of their likelihood. Monte Carlo maximum likelihood (MCML), as proposed by Geyer & Thompson (1992 ), is a simulation-based approach to maximum likelihood approximation applicable to general latent variable models. MCML can be described as an importance sampling method in which the likelihood ratio is approximated by Monte Carlo averages of importance ratios simulated from the complete data model corresponding to an arbitrary value of the unknown parameter. This paper studies the asymptotic (in the number of observations) performance of the MCML method in the case of latent variable models with independent observations. This is in contrast with previous works on the same topic which only considered conditional convergence to the maximum likelihood estimator, for a fixed set of observations. A first important result is that when is fixed, the MCML method can only be consistent if the number of simulations grows exponentially fast with the number of observations. If on the other hand, is obtained from a consistent sequence of estimates of the unknown parameter, then the requirements on the number of simulations are shown to be much weaker.     

植物液泡膜H+-ATPase及其在胁迫中的响应

V-ATPase存在于所有已知的真核生物中,在植物的生长、发育、信号转导和胁迫适应过程中发挥着重要的作用.近年来对V-ATPase的结构、功能和调节机制的研究进展较快,V-ATPase主要亚基已经完成序列测定及分析,并对各亚基生理功能、V-ATPase全酶复合体的组装、调控也有了较为深入的研究.该文在阐述植物细胞液泡膜H -ATPase的基本结构的基础上,介绍V-ATPase亚基组成、编码基因及在胁迫应答中的响应.

This document presents a survey of the statistical and combinatorial aspects of four areas of comparative genomics: gene order based measures of evolutionary distances between species, construction of phylogenetic trees, detection of horizontal transfer of genes, and detection of ancient whole genome duplications.     

An analysis of other countries’ international public relations in the U.S.

The purpose of this study was to examine the various aspects of international public relations by other countries in the U.S. Based on the Foreign Agency Registration Act (FARA) report in 2002, this study analyzed client, activity types, purpose of activity, and key U.S. partners for activity. This study found that (1) business organizations and central governments were major clients of international public relations in the U.S., (2) meeting with governmental officials and congressional leaders was the primary type of activity followed by information dissemination, and (3) economic purpose led by trade promotion was the primary motive for these activities.
