Design and Implementation of Examination System Based on .NET Structure [PDF]
, 2015 随着医疗体制的深入改革和发展，计算机网络技术的不断普及，以及信息化在全市各大医院的深度应用，很多医院正在逐步向规模化、集团化和网络化方向发展。由于集团化医院具有院区分散，职工数量多，职工层次不均等显著的特点，如何对集团医院的职工进行理论和业务能力考核，是我们现在必须面临的新课题。传统的考试方式需要把分散在集团医院的各分院的职工集中到一起再考试，效率低下，成本高昂，显然已经不适应现代化医院管理的需求，因此设计开发基于网络的医院考试管理系统是当前各医院各部门的迫切要求，同时在一定程度上改善医院行政管理的效率，

Research on the Volatility Spillover Effects of RMB Exchange Rate toward Domestic and Foreign Stock Markets----Based on Three-element BEKK-GARCH Model [PDF]
, 2016 经历持续数年的单边升值后，人民币走势在2015年发生逆转，8月份和年末的剧烈波动两度掀起了全球风险资产的抛售浪潮。在中国央行紧急干预之后，海外空头把香港作为替代选项，试图以抛售港币和卖空股指期货的投机策略押注内地经济硬着陆和香港联系汇率制崩溃。 这些最新例证表明，随着信息流动便利化和交易系统电子化的普及，原本孤立隔绝的单一市场变得越来越彼此依赖，信息的跨市场、跨资产传导诱发了许多前所未有的联动效应，波动的强度和深度日益加剧。在人民币国际化进程日益提速、国内金融体制改革渐趋深化的大背景下 ...
