实行巴塞尔委员会96协定的正态性检验

对实行巴塞尔委员会关于银行（金融）业风险监管的１９９６协定的基本假定之一。即证券资产回报服从条件正态分布进行了实证分析。证券资产包括股票和债券，分析采用了常规的偏度、峰度检验、直观的分位图（Ｑ－Ｑ图）和对应的Ｑ－Ｑ图相关系数检验。分析结果显示，Ｊ．Ｐ．Ｍｏｇａｎ关于预测波动率σｔ的模型和标准在我国证券市场有一定的实用性，我国的金融机构可以考虑试行巴塞尔委员会关于风险监管的９６协定。     

我国高科技概念股市场定价的实证分析

本文基于沪深两市 1 997、1 998两年的数据 ,对以电子信息行业和生物制药行业为代表的高科技概念股的股价行为进行了回归分析 ,建立了一个高科技概念股市盈率估价模型 .模型表明我国高科技概念股的市盈率仅仅与它的总风险相关 ,而与系统风险无关 .这与经典资本资产定价模型相冲突 ,对资本资产定价模型的进一步回归检验表明 ,证券资产平均收益率也仅与总风险相关 .对上述结果的可能解释是 :我国证券市场不符合资本资产定价模型的市场有效性假设 .     

当前资产证券化发展的风险监管及其模式选择

资产证券化作为一项金融创新和金融工具,在各国金融发展和改革中都发挥了重要作用。国际实践证明,资产证券化有助于增强金融资产流动性、优化融资结构以及提高货币政策效率。而在我国,资产证券化逐步从理论探索走向实证检验。现从资产证券化的监管原则出发,对证券化流程中的各风险点监管进行阐述,探讨我国进行资产证券化操作模式的选择,提出构建以市场和法规为导向的风险型监管,以及有效的分业监管的协调机制。     

银行业的“国际警察”——巴塞尔委员会

为加强风险监管而建本世纪70年代初,国际金融市场发生了一系列严重危机,为了加强国际银行业的风险监管,规范国际银行业行为,1974年12月,西方10国集团中央银行行长会议决定建立巴塞尔委员会,作为国际银行业风险监管的常设机构。1975年2月,巴塞尔委员会第一次会议召开,此后每年定期举行3至4次会议。目前,巴塞尔委员会的正式成员是比利时、加拿大、法国、德国、意大利、日本、卢森堡、荷兰、瑞典、瑞士、英国、美国的中央银行或银行监管机构的代表,其日常工作由国际

一.巴塞尔体系与内部控制制度 国际清算银行关于实施银行管理和监管协调委员会（简称巴塞尔委员会）成立于1975年,主要任务是：研究影响国际银行业务的问题;改善对国际银行监管的技术和效能;帮助改善全世界银行监管水平;与各国银行监管部门交换信息。巴塞尔体系是指巴塞尔委员会为了完成任务而编制的一系列关于银行监管的文件（也称为巴塞尔协议）。     

效用最大化投资模型的进一步分析

在考虑限制卖空风险证券的基础上,借助用函数,对无风险资产存在时证券投资组合优化模型进行研究,给出了期望效用最大化时无风险资产和风险证券投资权重的解析表达式.     

巴塞尔新协议与操作风险管理

操作风险管理已成为银行风险管理的重要内容。巴塞尔委员会首次将操作风险纳入第一支柱,并要求对操作风险配置资本。巴塞尔委员会关于操作风险的定义、分类、特征、量化模型和最佳管理实践为我国银行业强化操作风险管理提供了新的思路,国内商业银行应借鉴巴塞尔新资本协议的最佳实践,结合自身实际,建立完善操作风险管理体系。     

推动资产证券化市场建设的策略分析

资产证券化是以证券形式出售资产的结构性融资活动.资产证券化对于深化我国的金融体制改革、推动经济的发展具有重要意义.但是从目前的试点到资产证券化市场的深化,需要充分发挥政府的作用、完善相关法律法规、培育发行和流通市场、强化监管、构建社会信用体系.     

对市场上N种投资组合的分析

一、问题的提出在我国深化市场经济体制改革的进程中,短短几年,便在祖国大地出现了一个初具规模的新兴资本市场,掀起了一股又一股的投资热潮.市场也向投资者提供了很多种资产(如股票,证券……)供选择、投资.现市场上有n种资产S_i供投资者选择,某公司有数额为M的一笔相当大的资金可用作一个时期的投资.公司财务分析人员对这n种资产进行了评估,估算出在这一时期内购买S_i的平均收益率为r_i,并预测出购买S_i的风险损失率为q_i.考虑到投资越分散,总的风险越小,公司确定,当用这笔资金购买若干种资产时,总体风险可用所投资的S_i中最大的一个风险来度量.

Markedness and its Interpretation in Language Use

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.     

Features of Women's language

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.     

An Analysis of Catherine＇s Character——Wuthering Heights

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.     

Lower Paleozoic oil relationships within Williston Basin, Canada

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.     

低渗透非均质砂岩油藏启动压力梯度研究

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。     

On Tragic Consciousness In The Works By Ernest Hemingway

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.

Achieving Unusual States of Matter Under High Pressure

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-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

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-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

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
