正据NASA报告,2013年5月31日,一颗直径1.7英里的小行星与地球擦肩而过。若击中地球,产生的撞击很可能会带来毁灭性的影响,包括地壳破裂,频繁地震,火山喷发,烟尘铺天盖地,苍生不见天日,物种成批灭绝。还好,仅仅是擦肩而过。但是,就这么轻描淡写转瞬即逝的一擦肩,对人类何尝不是一个提醒?虽然人类拥有光辉的历史与先进的科技,但宇宙无垠,地球不过是荒漠的一粒沙,在万丈的黑暗中沿轨迹飘动,于疾行的星雨里凭机遇存亡。璀璨银河,我们人类可有可无,兴许轻轻的一阵太阳风,世界各地几千年的文化,每个灯火通明的城乡,所有纠结于爱恨中的男女,都会顷刻间化 相似文献

你知道,梵高在阿尔勒的画,几乎都有麦田的气味,看着看着,好像把一束麦穗放在齿间咀嚼,麦粒上还带着夏天的日光曝晒过的气味。有些画是没有气味的,画海没有海的气味,画花没有花的气味,徒具形式,很难有深刻的印象。我觉得,元朝的王蒙,他的画里就有牛毛的气味。有一次,在上海美术馆看他的《青卞隐居图》,我闭着眼睛,那些停留在视觉上的毛茸茸、卷曲躁动的细线,忽然变成 相似文献

我站在荷塘边,欣赏荷花美景。抬头望去,一潭绿水倒映着远山的倩影,像一幅隽永的山水画。静水那边,由近而远,一片迷人的荷花盛开了。在晨光的照射下,一株株高高低低的花箭,升起一只只含苞欲放的花蕾,充满生机勃勃的生命气息。这些粉红色的小精灵,经过严冬的煎熬,春日的孕育,才将绷得很紧的花骨朵悄悄张开。荷花散发清香,梦想,张开翅膀,在荷塘之上划出一道道优美的弧线。翅,在一静立的花蕾上停留,姿态优雅。我架起相机,成为蜻蜒的爱物,一只只飞来飞去的蜻蜒,带着荷花的这时,一只不知从哪里飞来的蜻蜒,踮着细脚,轻展双目光透过长焦镜头,把这至美的景色永远定格。自古以 相似文献

I.F. Clarke 《Futures》1985,17(2):170-184
With this survey of developments in the futures field since 1945, I.F. Clarke completes his present series for Futures. He makes two major points: that forecasting techniques have become essential tools in the management of change; and that nuclear weapons and ecological problems have added a moral dimension to the study of the future. In the next issue of Futures he will start a new series on the range of future-thinking in the USA, from the expectations of the first settlers to the Star Wars programme. 相似文献

银监会分设后,人民银行将专司货币政策、金融稳定、金融服务三大职能。作为人民银行的分支机构,基层人民银行的工作重心也将从金融监管调整到这三大职能上来。人民银行的科技部门,就要积极运用科技手段,为人民银行履行新的职能发挥“服务、支持、促进、发展”的作用。一、围绕三大职能搭建五大平台经过“六五打基础、七五作准备、八五大发展”几个阶段后,人民银行相继实现了核算电算化、清算网络化和办公信息化。特别是近一两年来,陆续开通了大额支付系统、信贷登记咨询系统、会计四集中系统、金融信息服务网站等系统,人民银行信息化水平又… 相似文献

Abstract: Prior research has shown the prevalence of measurement error in models used to estimate aggregate discretionary accruals. In these models, the incremental information content of the various components of accruals is ignored. Limited prior research and data gathered from firms under Securities and Exchange Commission (SEC) litigation indicate that managers use either one or more than one component of accruals simultaneously, in a consistent way to manipulate bottom-line earnings in a given direction. I propose two measures that capture the consistency between the discretionary components of accruals and test their significance in earnings management (EM) detection in firms that have artificially added accrual manipulation and firms that were targeted by the SEC for accrual manipulation. There is evidence that this information is incrementally useful in detecting EM. This finding paves the way for improvements in the discretionary accruals measure by including consistency information from the components of aggregate accruals. 相似文献

Abstract The Society of Actuaries undertook a three-phase research project on mortality improvement in the three NAFTA countries: Canada, Mexico, and the U.S. Phase 1 consisted of a literature review of papers on projecting mortality levels in the future and a study of the trend in mortality improvement during this century. Phase 2 consisted of a discussion of different facets of modeling mortality rates at a seminar attended by 79 experts (actuaries, demographers, economists, and medical researchers) representing different countries. The last session of the seminar consisted of the completion of a survey by the attendees to obtain input for Phase 3, which would analyze the impact of mortality improvement on the social security system of each country. This paper summarizes the results of the survey. The survey results illustrate the difficulty in forecasting mortality levels, because the effects of many factors that could have significant impact on mortality rates are unknown. This suggests the need for dynamic forecasting, which allows for the possibility of random shocks. A majority of the survey respondents believe that stochastic forecasting models, despite their complexity, have significant potential to add value. Respondents also believe that both historical data and cause-specific mortality forecasts are useful as input and also in validating forecasts of the aggregate levels of mortality. The challenge is to develop more sophisticated forecasting models to produce results that are relatively easy to interpret and to communicate these results to the desired audiences, including the public and policymakers. The survey results suggest that the aggregate effect of lifestyle changes, medical advances, diseases, catastrophe, and physical environmental changes is an increase in life span. However, there is much uncertainty about the future. Respondents expect that beyond the year 2020 the mean annual rate of reduction in mortality for males age 65 and over will average about 0.58% for Canada, 0.76% for Mexico, and 0.67% for the U.S. The results for the female age 65 and over population are 0.64%, 0.83%, and 0.70%, respectively. The age 65 and over population is expected to see larger percentage reductions in mortality than the 0–14 and 15–64 populations. The reductions in male and female mortality will be ultimately the same, and the mortality levels in the three countries will ultimately converge, although differences may persist for decades. 相似文献

The separation of a unit of account (UoA) from a medium of exchange (MoE) in the commodity–money system is investigated by considering explicitly a seller's choice of UoA in terms of either an MoE or a unit of metal weight. If the likelihood of debasement of an MoE and its rate are high enough, the price is posted in terms of a unit of metal weight rather than an MoE. Interestingly, this MoE–UoA separated equilibrium yields the flexible nominal price, whereas an MoE–UoA integrated equilibrium yields the sticky one. This implies the nominal price rigidity in the fiat‐money system where MoE and UoA are integrated. 相似文献

一、引言随着国民经济的不断发展,银行业务与外部企业的联系越来越密切。银行正逐步成为现代经济活动的中心,作为数据处理核心的银行业务应用也越来越大型化、越来越复杂化,因此许多银行也把软件项目逐步由原来的自主开发转变为与公司合作的方式,或直接外包开发的方式,银行本身的技术人员也逐步由开发转向项目管理。二、项目外包的分类银行项目的外包有以下几种情况:①部分子系统外包,有时由于银行的软件项目太大,单靠银行自身的开发力量基本无法在预定的时间内完成项目,只好把相对独立的部分外包;②直接购买软件公司的成熟产品,有些金融软… 相似文献

银行管理信息平台建设发展的思考 总被引:4,自引:0,他引:4
一、目前国内银行IT发展现状及面临的问题 银行数据集中工作的完成,标志着银行的业务由电子化建设阶段转入信息化建设阶段.一方面银行数据的集中提供了丰富全面的基础数据,面对日益庞大的数据源,如何将数字转化为对银行有用的信息,并从中发现知识,为银行的经营决策提供支持,是摆在银行IT人员面前的一个亟待解决的问题.另一方面用户对银行信息的需求日益增长,如果银行没有一套完整、实用的信息管理系统,将对业务发展非常不利.南京爱立信公司倒戈花旗银行事件曾经轰动一时,其中一个重要原因就是中国本地银行不能满足爱立信全球总部对南京爱立信公司的要求:每周财务上报和每天贷款限额管理.这一事件为中国商业银行的未来发展敲响了警钟,如果不加快管理信息系统的开发,迅速提升业务管理水平,类似的事件还会接连不断地发生,并最终导致国内商业银行在同国外商业银行的竞争中全面溃败. 相似文献

Empirical studies suggest that time-series regression estimates of the degrees of operating and financial leverage have a tendency to produce measures less than one. According to ex ante theory, these measures should be greater than one for firms operating above the breakeven point. There have also been suggestions that the biases in these estimates may be attributable to an underlying increase in unit sales. This work presents evidence that these counter-intuitive measures are produced by changes in the firm's operating parameters (unit price, variable cost, fixed cost and interest payments). It further suggests that attempts to control for the underlying change in unit sales substantially increase the volatility of predicted estimates. 相似文献
