实现银行信息系统高效运维的探讨

随着银行信息化水平的提升,IT系统越来越复杂,如何维护好这些庞大的系统,保障稳定运行成为IT部门最重要的任务。虽然各银行都投入了巨大的人力物力建设运维机构,但从近几年发生的重大生产事件来看,运维效率不高是引发业务长时间中断的罪魁祸首。要解决这一问题,必须从运维体制和流程入手,在各个环节同步提升IT运维效率。     

端到端的IT性能管理

IT的价值体现在对业务的支撑上,为了确保IT系统7×24的连续运行以满足业务的经营发展需求,我们需要有一个完整的运维管理体系来优化IT运维管理服务流程,持续提升管理水平。当前运维管理的最佳实践ITIL和ISO20000运维管理框架都定义了事件管理和服务级别管理等关键流程,但并没有指定具体的实现方法。本文简单介绍了面向业务的IT性能管理的几种思路,可以用于量化IT部门提供的服务级别水平,实现IT事故的快速定位和恢复,为事件管理和服务级剐管理流程的实施提供基础。     

日本灾后重建的辐射力

日本东北部海域发生的地震以及海啸因其所引发的核泄漏危机而持续发酵,由于其是世界第三大经济体,这必然会对全球经济产生重大的辐射作用。虽然目前福岛核电站的危机还没有得到有效控制,但我们倾向于相信事件不会最终走向导致日本经济大面积瘫痪的极端状态。核泄漏事件的进一步发展将主要影响日本灾后重建的进度。因此我们认为,短期来看,本次灾难对资本市场所引发的直接冲击和恐慌应该已近尾声。     

如何有效提升基层央行科技独立运维能力

一、提升基层央行科技独立运维能力的背景 在2007年人民银行科技工作会议上,科技司司长文四立在主题报告中强调指出:"随着信息化发展的不断深入,人民银行科技部门负责运维的系统越来越多,工作难度逐渐加大,特别是国库信息处理系统全国横向联网推广工作的快速启动,成为人民银行第一个面向全社会公众服务的7×24小时运行的业务系统,这对系统的持续安全稳定运行提出了更高的要求,对科技人员的运维技术水平提出了更高的要求."     

事件树分析法在应对淘宝网促销交易高峰期间的应用及思考

随着银行应用系统不断创新发展,信息系统生产运维中心环境越来越复杂,如何有效控制重大生产事件的发生,及时发现生产运行过程中存在的隐患,提前做好防范措施;如何有效控制重大生产事件发生后对业务的影响,使信息系统在第一时间内恢复正常运行等,已成为数据大集中下生产运行应急管理的重点研究课题。     

银行业IT运维管理监控指标体系的研究

正从信息系统生命周期理论出发,银行信息系统大致分为规划与设计、开发与测试(或购买)、实施、运维管理与持续改进五个阶段。而前三个阶段从时间角度看,只占整个周期的20%,其余时间基本上是对其进行运行维护。这就决定了IT运维服务在银行信息化建设和运行中的核心地位,而定量、实时地交易数据、事件和性能指标成为判断信息系统安全运行状态的主要依据。一、研究的背景和意义1.业务发展的客观需要。为了充分发挥运维监控的预     

气候变化对经济金融系统性冲击的物理风险研究

中国作为全球最大的发展中国家,其综合实力伴随着经济、科技的快速发展而不断增强。但我国的极端气候事件趋多趋强,气候风险水平呈上升趋势,影响我国经济社会的发展。金融作为经济运行的核心,在宏观经济中有着举足轻重的作用。为了研究气候变化与经济金融稳定之间的关系,本文对极端气候事件损失体系和区域经济金融稳定性综合体系进行指数合成并构建面板模型探讨气候变化中气温和降水量因素的变动和极端气候事件对区域金融稳定的影响,得出气候变化的物理风险通过极端气候事件对经济发展和金融稳定有负面影响,并根据实证结果提出完善绿色金融市场和优化信息披露制度的政策建议。     

银行业集中式数据中心信息系统运维管理的形势分析与应对策略

按照系统规划、建设、运维管理、持续改进的信息系统生命周期模型理论,国内金融业信息系统的重点,逐渐从基础设施建设和应用升级换代转向数据中心生产运维和IT服务管理。正如国内一些信息化专家所言,目前国内信息系统正处于从基础设施建设向IT服务管理能力建设转变的关键时期。     

Debt and Taxes and Uncertainty

With a graduated personal tax schedule, Miller showed that there could be an equilibrium debt supply for the corporate sector as a whole. In the presence of uncertainty there is also a unique debt/equity ratio for each individual firm, and this ratio is related to the firm's operational risk characteristics. However, if firms merge and spin off in response to tax incentives, the identity of firms is ambiguous and only the corporate sector is a meaningful construct. These arguments are developed in both discrete and continuous models that employ extensions of the arbitrage-free pricing theory.     

教育与资本怎样的前景怎样的现实

来自政府的声音: "动员各种社会资源,发展教育" 此次论坛上财政部长助理张少春的发言是最受关注的发言之一.他的演讲传达出的信息有这样几方面:第一,谈到现实,他认为全社会对教育的巨大需求与我国公共投入不足已成为我国教育事业发展的突出矛盾.近年来,以公共部门投入为主,多渠道筹措教育经费的教育投入机制成为解决这一问题的重要途径,也使得公共部门与私营部门在教育领域的合作日益密切.第二,谈到前景,他认为,1.中国经济持续、快速的增长对高技能人才产生巨大的需求,这为私营部门的参与提供了广阔空间.2.随着公共财政职能的不断完善,财政资金将在各项教育事业中重新进行分配,进一步优化财政支出结构,提高资金的使用效率.在"十一五"期间,我国将把公共支出的重点转移到农村.我们将逐步把全体农村适龄儿童的义务教育全部纳入公共财政体制.     

Director gender and mergers and acquisitions

Does director gender influence CEO empire building? Does it affect the bid premium paid for target firms? Less overconfident female directors less overestimate merger gains. As a result, firms with female directors are less likely to make acquisitions and if they do, pay lower bid premia. Using acquisition bids by S&P 1500 companies during 1997–2009 we find that each additional female director is associated with 7.6% fewer bids, and each additional female director on a bidder board reduces the bid premium paid by 15.4%. Our findings support the notion that female directors help create shareholder value through their influence on acquisition decisions. We also discuss other possible interpretations of our findings.     

Political corruption and mergers and acquisitions

This research examines the relation between political corruption and mergers and acquisitions (M&As). We find that local corruption increases firm acquisitiveness but decreases firm targetiveness. The levels of corruption in acquirer areas relate positively to the bid premiums and negatively to the likelihood of deal completion. Corruption motivates acquiring firms to use excess cash for payment, which mitigates the negative effect of corruption on acquirer shareholder value. The evidence indicates that acquisitions help acquiring firms convert cash into hard-to-extract assets and relocate assets from the high to low corruption areas, thereby shielding their liquid assets from expropriation by local officials.     

Trust and cross-border mergers and acquisitions

A number of studies suggest that social trust matters for investment. Using different measures of trust from World Values Survey, we show that countries where people display higher levels of trust engage in more cross-border M&A activities. When they do, these acquirers pay lower premiums. To the extent that these acquirers also tend to engage in larger acquisitions as well, our findings suggest that a larger selection pool of potential targets and higher value targets enable these acquirers to negotiate for lower premiums. We do not find evidence of the significant effect for target country trust levels. Hence, trust may benefit those acquiring firms in cross-border transactions.     

Tournament-based incentives and mergers and acquisitions

This research examines the relation between tournament-based incentives, which are proxied by the difference between a firm's CEO pay and the median pay of the senior managers, and mergers and acquisitions (M&As). We find that tournament-based incentives are positively related to firm acquisitiveness and acquiring firms' stock and operating performance. Further analysis indicates that positive acquisition performance increases the likelihood of the CEO being promoted from inside the acquiring firm. Our evidence is consistent with the view that tournament-based incentives motivate acquiring firms' managers to make greater efforts and take more risk that result in superior acquisition performance.     

Corporate Innovations and Mergers and Acquisitions

Using a large and unique patent‐merger data set over the period 1984 to 2006, we show that companies with large patent portfolios and low R&D expenses are acquirers, while companies with high R&D expenses and slow growth in patent output are targets. Further, technological overlap between firm pairs has a positive effect on transaction incidence, and this effect is reduced for firm pairs that overlap in product markets. We also show that acquirers with prior technological linkage to their target firms produce more patents afterwards. We conclude that synergies obtained from combining innovation capabilities are important drivers of acquisitions.     

East and west and north and south : A preliminary model

The Brandt report and other proposals for a new North-South world order continue to be the focus of lively debate, yet it is often argued that little concrete has emerged from their recommendations. A major reason for this, the author argues, is that the East-West conflict component is not sufficiently taken into consideration-East-West tensions are a severe constraint on and a determining factor of North-South relations. Using influence diagrams, the author develops a flexible framework for discussion and assessment of N/S-E/W relations.
