长江三角洲城市群洪涝灾害脆弱性评估及影响因素分析

长江三角洲城市群人口、财产、基础设施高度密集,暴雨洪涝灾害带来的影响越来越大,对该区域城市洪涝灾害脆弱性进行评估是保障长江三角洲区域一体化、可持续发展的基础。以长江三角洲城市群中心区27个城市为研究对象,基于超效率DEA模型,将洪涝灾害脆弱性看作一个负面“生产活动”,构建城市洪涝灾害脆弱性评估模型,在分析脆弱性空间分异特征的基础上确定该地区城市洪涝灾害脆弱性的主要影响因素。结果显示：从整体上看,长江三角洲城市群洪涝灾害脆弱性水平差异较大,安徽及浙江远高于江苏和上海,其中,上海的洪灾脆弱性最低;从空间上看,脆弱性分布有明显的地域集聚特征,脆弱性高的城市分布在浙江东南沿海和安徽南部丘陵地区;降雨量、城市发展水平及基础设施的完善性等因素对城市洪涝灾害脆弱性影响显著。     

信息技术对审计的影响研究

随着信息技术在社会经济生活中的全方位渗透,适用于传统经济环境的审计理论、方法与技术需要变革以适应现代组织的各类日常运营和活动,通过调研信息技术在审计中的具体应用,从12个方面对信息技术进步与审计发展面临的问题和趋势进行系统性研究。研究认为,信息技术促使审计职能从审计为主变为审计与管控并重,审计范围从经济安全变为经济与信息安全并重,审计内容从财务为主变为财务与业务并重,审计对象从账本变为数据库,审计模式从事后变为事前事中事后全包含,审计方式从现场勘察为主变为远程分析为主,审计介质从纸质变为电子,审计证据从有形变为无形,数据来源从抽样变为全样本,测试内容从人工系统变为信息系统,工作形式从审计合作变为审计协同,风险计算从依赖审计人员经验变为依据系统模型,这些变革极大地推进了审计向现代化方向发展。     

Camera-Related Behaviors during Video Recorded Medical Interactions

Video recording provides an objective record of the content of medical interactions. However, there is concern that cameras may be reactive measurement devices that alter what normally transpires during interactions. This study addressed potential reactivity of cameras in medical interactions. Interactions between 45 patients and 14 medical oncologists were video recorded and coded for camera-related behaviors. Eleven of 45 patients performed none of the behaviors. Among the other patients, camera-related behaviors were infrequent and, on average, constituted about 0.1% (one-tenth of one percent) of total interaction time. Behaviors occurred most often in very early stages of interactions, and when physicians were absent from the room. Seven physicians showed camera-related behaviors, comprising less than 0.1% of the time they were in the interaction. Results suggest video recording can provide nonreactive means of studying medical interactions.

State transition modeling of complex monitored health data

This article considers the analysis of complex monitored health data, where often one or several signals are reflecting the current health status that can be represented by a finite number of states, in addition to a set of covariates. In particular, we consider a novel application of a non-parametric state intensity regression method in order to study time-dependent effects of covariates on the state transition intensities. The method can handle baseline, time varying as well as dynamic covariates. Because of the non-parametric nature, the method can handle different data types and challenges under minimal assumptions. If the signal that is reflecting the current health status is of continuous nature, we propose the application of a weighted median and a hysteresis filter as data pre-processing steps in order to facilitate robust analysis. In intensity regression, covariates can be aggregated by a suitable functional form over a time history window. We propose to study the estimated cumulative regression parameters for different choices of the time history window in order to investigate short- and long-term effects of the given covariates. The proposed framework is discussed and applied to resuscitation data of newborns collected in Tanzania.

我国区域金融发展与经济增长的关系研究——基于面板数据的实证研究

运用1980—2004年间相应经济指标的面板数据对我国东、中、西部经济增长与金融发展进行了实证分析,结果表明,中西部地区更多的依靠信贷规模扩张来推动经济增长,而东部地区更多的依赖于金融效率的提升。     

信息化环境下审计内容与技术方法探讨

随着被审计单位各种信息系统的应用和会计信息化环境的逐渐形成,审计的内容与技术方法也发生了巨大的变化,审计内容转变为会计信息系统安全性审计和电子财务数据准确性审计两个方面。对会计系统安全性审计主要包括物理安全、技术安全和组织与管理安全几个方面;对电子财务数据准确性的审计一般分为数据采集、转换、清理与分析四个阶段。这些技术方法既有传统审计技术方法在信息化环境下的延伸,也有各种特定的IT审计技术。从长远上看,以智能审计专家知识库等IT审计技术将成为信息化环境下审计技术方法的未来发展趋势,对其方法进行研究具有很大的理论价值和现实意义。

中国高龄老人生活自理能力纵向动态研究

利用"中国老年健康长寿跟踪调查"1998年、2000年、2002年的跟踪数据分析中国高龄老人ADL的变动趋势及其影响因素。个体增长模型结果显示,高龄老人ADL状况随年龄增长出现了明显的下降趋势,ADL个体差异十分显著。个体之间的差异解释了ADL总差异的31.13%。经历三次追踪调查的高龄老人ADL均值较高,状况较好,下降速度较慢;基期具有3-4项残障的高龄老人,未来ADL下降最为迅速;基期ADL水平高的高龄老人,ADL下降较慢。从ADL的个体影响因素来看,对于基期ADL水平影响最大的变量是"年龄"、"疾病状况"以及"居住安排"等,而对观测期ADL变动速度影响最大的变量是"年龄"以及"过去是否经常从事体力劳动"等。
