上市公司会计信息失真的现象在我国证券市场存在较为普遍,其对投资者的利益造成严重损害,以致使企业失信于广大投资者,并直接使企业的持续经营受到影响,严重危害我国经济秩序和社会稳定,对会计信息失真的治理迫在眉睫。本文首先较为客观、全面地界定了会计信息失真的含义,介绍了我国上市公司会计信息失真的现状及危害,然后从经济学角度入手着重分析了会计信息造假的成本效益,并结合统计学、决策学等相关知识,对我国上市公司会计信息失真的根源展开讨论,得出会计信息的原因,据此总结出防范的对策。文章最后笔者提出了关于构建会计信息造假风险成本模型的初步设想,为我国上市公司会计信息规范工作表达了自己的愿望。  相似文献

上市公司是证券市场的基石,其行为的规范与否及其财务状况的好坏将直接影响到证券市场的发展和投资者的利益。而在市场经济条件下,每个企业绝对地防止财务失败是不现实的,在特定的条件下,总会有一些企业陷入财务失败的困境,然而人们面对这样的困境不是无能为力的,企业财务失败是可以提前预测的。本论文正是基于这样的思想,在总结国内外有关企业财务失败研究成果的基础上,论述了企业财务失败与破产、企业财务失败与ST的关系。在对企业财务失败预警的含义、功能及特征等进行了必的简单介绍之后便进入实证研究部分。实证研究部分主以我国深、沪两市96年前上市的260家A股公司为研究样本,采用2005年至2007年三年的实际财务数据的均值,运用支持向量机(SVM)方法,随机抽取其中的200家企业的数据建立判别模型,运用自身验证法对模型的稳定性加以分析,又运用外部数据法,使用剩余60家上市公司的数据对模型的预测能力进行了验证。结果表明:通过对21个变量指标进行分析,SVM的准确率很高,其预测的准确率为94%。而后对模型的可行性和有效性进行了验证,正确的判别率达到了91.6667%,结果表明模型是可行的。从而建立了判断上市公司财务危机的数学模型。  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  相似文献

Wuthering Heights, Emily Bronte's only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.  相似文献

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that  相似文献
