联机分析挖掘(OLAM)方法在银行信用风险评估中的应用     

方洪全  曾勇 《中国软科学》2004,(10):126-130,139

现有文献多从某一具体方法讨论信用风险评估模型，受样本数量的约束，所建模型并不足以反映金融机构所处的信用风险水平。本文以1333笔实际贷款记录建立数据方，运用数据挖掘方法揭示了信用风险基本特征，建立起两阶段的信用风险评估体系，实证结果表明本模型是有效的，为金融机构建立风险评价体系提供有力的支持。  相似文献

Compelled Disclosure of Scientific Research Data     

William Gardner 《The Information Society》2004,20(2):141-146

Federal legislation requires that research produced with federal funding be available to the public under the Freedom of Information Act. I raise a concern that this power might be used to harass scientists. The goal of data sharing, however, is important, and should be facilitated through electronic data archiving.  相似文献

Awkwardness of becoming a boundary object: Mangle and materialities of reports,documentation data,and the archaeological work     

Isto Huvila 《The Information Society》2016,32(4):280-297

Information about an archaeological investigation is documented in an archaeological report, which makes it the boundary object par excellence for archaeological information work across stakeholder communities such as field archaeologists, heritage managers, and land developers. The quality of reports has been a subject of debate, and recently it has been argued that more emphasis should be placed on making primary research data at least similarly available. This study explores the changing materialities and reciprocal formation of documents and their users with the advent of digitization, and how documents form and lose their status as boundary objects in these processes. The study posits that in order to be functional, a boundary object needs to provide a disclosure that makes it accessible to cognate communities. Further, it shows how assumptions about the functioning of the human and nonhuman (material artifacts) influence the ways in which archaeologists conceptualize the preservation and archiving of archaeological information and the role and potential of different types of digital and paper-based documents. This article is based on an interview study of Swedish archaeology professionals (N = 16) with theoretical underpinnings in the notions of boundary objects, mangle of practice, and disclosure.  相似文献

中国月平均地表反照率的估算及其时空分布   总被引：12，自引：1，他引：12  

蔡福  祝青林  何洪林  刘新安  于贵瑞 《资源科学》2005,27(1):114-120

本文利用1948年～2003年55年平均的NCEP/NCAR(National Center for Environmental Prediction/National Center for Atmospheric Research,美国国家环境预报中心/美国国家大气研究中心)再分析辐射资料和中国10km×10km土地利用类型图,借助GIS、GrADS(Grid Analysis and Display System,网格分析与展示系统)等空间化技术,采用图形回归处理等方法建立了国家尺度的10km×10km的中国地表月平均反照率栅格图.研究表明,估算的地表反照率的季节变化十分明显:冬季(1月)最大,夏季(7月)最小,春秋季(4月和10月)次之,且秋季比春季稍大;空间分布与地理纬度、地势高低和距海远近关系很大,西部地区大于东部地区,北部地区大于南部地区,高海拔地区大于丘陵和平原地区.几种土地覆被类型反照率的估计值如下:林地、水稻和小麦地为0.17～0.23;草地为0.20～0.32;雪被为0.44～0.76;沙漠为0.35左右.总的来说,估算结果比较合理,能够较好地反映出中国地表反照率的时间、空间变化特征,也能反映多年气候平均值的特点.因此,在目前气候要素之一的多年平均的地表反照率研究较少的情况下,利用多年平均NCEP/NCAR再分析资料与土地利用类型图进行回归处理不失为是一种相对合理的方法.  相似文献   

Privacy Rights and Protection: Foreign Values in Modern Thai Context     

Krisana?KitiyadisaiEmail author 《Ethics and Information Technology》2005,7(1):17-26

The concept of privacy as a basic human right which has to be protected by law is a recently adopted concept in Thailand, as the protection of human rights was only legally recognized by the National Human Rights Act in 1999. Moreover, along with other drafted legislation on computer crime, the law on privacy protection has not yet been enacted. The political reform and the influences of globalization have speeded up the process of westernization of the urban, educated middle-class professionals. However, the strength of traditional Thai culture means that a mass awareness of the concept of privacy rights remains scarce. This paper explicates the Thai cultural perspective on privacy and discusses the influence of Buddhism on privacy rights, including the impacts of globalization and the influence of Western values on the country’s political and legal developments. The paper also discusses the legal provisions regarding privacy protection, and the debates on the smart ID cards policy and SIM cards registration for national security.  相似文献
