会计信息失真现象与社会环境、经济环境、市场经济的发育程度等企业的外部环境息息相关,但单位内部控制系统弱化是一个更重要、更直接的内部因素。因此,建立和加强单位的内部控制,使内部控制合理设计并有效实施,才能最大可能地防止会计造假等错弊行为的发生,保证会计信息的真实、完整、相关、透明,才能促使企业价值的增值。本文以中小企业作为研究对象,对中小企业如何加强与完善内部控制系统作了一些探讨,提出了一些具体的措施。 相似文献

在一个发育不完善、组织效率较低的商品或资本市场中,不同的市场主体拥有不同信息并产生预期模式的差异,由于交易者之间的信息屏障在短期内无法有效消除,导致预期的异质化长期存在并使市场仅具有局部理性.局部理性市场价格的稳定性取决于理性投机与非理性交易行为的力量对比,而不成熟市场经常显现的过度波动性则往往是理性投机处于弱势的表现. 相似文献

Modeling for Risk Assessment of Neurotoxic Effects 总被引:2,自引:0,他引:2
The regulation of noncancer toxicants, including neurotoxicants, has usually been based upon a reference dose (allowable daily intake). A reference dose is obtained by dividing a no-observed-effect level by uncertainty (safety) factors to account for intraspecies and interspecies sensitivities to a chemical. It is assumed that the risk at the reference dose is negligible, but no attempt generally is made to estimate the risk at the reference dose. A procedure is outlined that provides estimates of risk as a function of dose. The first step is to establish a mathematical relationship between a biological effect and the dose of a chemical. Knowledge of biological mechanisms and/or pharmacokinetics can assist in the choice of plausible mathematical models. The mathematical model provides estimates of average responses as a function of dose. Secondly, estimates of risk require selection of a distribution of individual responses about the average response given by the mathematical model. In the case of a normal or lognormal distribution, only an estimate of the standard deviation is needed. The third step is to define an adverse level for a response so that the probability (risk) of exceeding that level can be estimated as a function of dose. Because a firm response level often cannot be established at which adverse biological effects occur, it may be necessary to at least establish an abnormal response level that only a small proportion of individuals would exceed in an unexposed group. That is, if a normal range of responses can be established, then the probability (risk) of abnormal responses can be estimated. In order to illustrate this process, measures of the neurotransmitter serotonin and its metabolite 5-hydroxyindoleacetic acid in specific areas of the brain of rats and monkeys are analyzed after exposure to the neurotoxicant methylene-dioxymethamphetamine. These risk estimates are compared with risk estimates from the quantal approach in which animals are classified as either abnormal or not depending upon abnormal serotonin levels. 相似文献

目前民事检察监督存在监督范围狭窄、监督方法过于单一、监督流于形式等诸多问题;针对这些问题,有必要采取一系列对策,如转变观念、完善立法、建立检察人员和审判人员轮换机制,以完善我国民事诉讼检察监督制度,实现司法公正。 相似文献

技术和消费的“双升”加快了新零售服务供应链的形成和产生,同时也通过驱动其质量系统的协同改进及动态演化实现持续的发展。本文从创新驱动质量的动态视角,分析创新驱动下新零售服务供应链中多主体协同质量改进的运行机制和动态演化过程,运用演化博弈方法分析构建多主体协同的动态演化博弈模型,以此分析新零售服务供应链协同质量改进中各参与主体的博弈策略选择,并利用雅克比矩阵判断其策略稳定性。研究表明:在多元参与主体利益诉求得到满足的前提下,多主体协同质量改进能够保持系统稳定状态;多主体间的质量势差与协同质量改进稳定性呈现出反比关系;良好的质量协同效应、独立的内部监督机制等能有效的促进协同质量改进系统稳定。 相似文献

Estimation for Continuous Branching Processes 总被引:1,自引:0,他引:1
Ludger Overbeck 《Scandinavian Journal of Statistics》1998,25(1):111-126
The maximum-likelihood estimator for the curved exponential family given by continuous branching processes with immigration is investigated. These processes originated from population biology but also model the dynamics of interest rates and development of the state of technology in economics. It is proved that in contrast to branching processes with discrete space and/or time the MLE gives a unified approach to the inference. In order to include singular subdomains of the parameter space we modify the MLE slightly. Consistency and asymptotic normality for the MLE are considered. Concerning the asymptotic theory of the experiments, all three properties LAQ, LAN, and LAMN occur for different submodels 相似文献

Data envelopment analysis (DEA) is the most commonly used approach for evaluating healthcare efficiency [B. Hollingsworth, The measurement of efficiency and productivity of health care delivery. Health Economics 17(10) (2008), pp. 1107–1128], but a long-standing concern is that DEA assumes that data are measured without error. This is quite unlikely, and DEA and other efficiency analysis techniques may yield biased efficiency estimates if it is not realized [B.J. Gajewski, R. Lee, M. Bott, U. Piamjariyakul, and R.L. Taunton, On estimating the distribution of data envelopment analysis efficiency scores: an application to nursing homes’ care planning process. Journal of Applied Statistics 36(9) (2009), pp. 933–944; J. Ruggiero, Data envelopment analysis with stochastic data. Journal of the Operational Research Society 55 (2004), pp. 1008–1012]. We propose to address measurement error systematically using a Bayesian method (Bayesian DEA). We will apply Bayesian DEA to data from the National Database of Nursing Quality Indicators® to estimate nursing units’ efficiency. Several external reliability studies inform the posterior distribution of the measurement error on the DEA variables. We will discuss the case of generalizing the approach to situations where an external reliability study is not feasible. 相似文献
