电子结算作为一种新兴的在线资金交换方式,解决了人们跨地域经济活动的关键问题。由于其在大额与小额结算方面的应用,提高了金额系统资金的周转速度和使用效率,节省了服务成本。相比于发达国家,我国实现电子结算的业务比重仍然偏低,但成长势头良好,如果能解决目前在认证、安全、法律等几个方面存在的漏洞,会有助于其更广泛的应用。 相似文献

In the aftermath of Enron and the collapse of Arthur Andersen, new “independent” institutions were created to oversee financial auditing. Based on a modified version of Lukes’ multidimensional model of power, we first investigate how the creation of the Canadian Public Accountability Board (CPAB) has affected the dynamics of power among the main players enlisted in Canada’s regulation of public accounting. Our findings strengthen the view that a “form of allegiance” was, at the time of data collection, developing between CPAB and the largest Canadian accounting firms. Through a second analytical movement, we extend the boundaries of our argument, showing that patterns of resistance against the logic of arm’s length regulation operate in a variety of audit regulatory sites. Our conclusion points, in particular, to the spatial gap - and incidentally the limitations - of any attempt to control and supervise a globalized industry from a national or regional perspective. 相似文献

探讨心电向量图诊断心房肥大、心室肥厚的临床价值。应用心电工作站对收集的病例进行观察检测。对比心电图和心电向量图诊断心房肥大、心室肥厚的敏感性、特异性、准确性。结果为心电向量图对心房肥大、心室肥厚诊断的敏感性及准确性较心电图高,且具有一定的特异性。心电向量图在心房肥大、心室肥厚的诊断中可弥补心电图的不足,是值得推广应用的。 相似文献

ABSTRACTIn recent years, due to the popularity of wearable and implantable devices, the application of electrocardiogram (ECG) recognition for human identification has become more and more feasible. ECG is an important biological signal, which can be used for the diagnosis of cardiovascular diseases. After more than 20 years of research, it has been established that the ECG signal is unique to individual. This article intends to summarize the previous algorithms and applications in ECG recognition for human identification, while introducing the concept, history, algorithm summary, hardware platform etc. In addition, we also discuss some important issues in order to provide a helpful guideline for future research. 相似文献

现今社会竞争日益激烈,青年人的精神压力不断增
加。现有研究表明,自然环境对人们的身心健康有着积极的影
响,但目前与人们生活密切相关的城市中的自然环境对健康
的促进作用研究较为缺乏。通过采集参与者在2段差异性高的
滨河实景环境中行走的生理信号和眼动数据,探究不同滨河步
道景观下青年人的压力缓解情况和视觉特征。研究结果表明:
1)以SDNN、RMSSD和Lorenz散点图为代表的心率变异性
特征(HRV)在不同区段的滨河步道下呈现明显差异,绿化程
度高的场景对压力的缓解作用更强;2)不同场景下的视线特征
与压力缓解有一定的关联性,行人的视线多偏向于步道滨水侧
开敞度高的空间,经过绿化程度高或有休憩空间的滨河步道场
景时,行人的视线更分散,压力缓解效果更佳。将缓解压力作
为滨河步道的景观功能之一,通过主动干预有针对性地进行滨
河景观类型与植物种植的改造,以期达到更好的滨河步道环境
提升效果。 相似文献
