公允价值会计的反思

公允价值与历史成本之间的孰优孰劣一直就伴随着争议。我们不应该忽视公允价值固有的内涵缺陷及其与财务会计概念框架的冲突,以及在金融危机中的顺周期效应。文章将从会计决策有用目标和会计信息质量以及准则的经济后果角度重新反思公允价值会计。     

供应链管理影响因素及评价指标分析

本文认为,供应链凝聚、信息获取能力、区位优势以及信息共享是影响供应链管理成功的四个主要因素,对这四个变量难以直接进行测量。供应链管理成功影响因素测评指标体系是一个多指标的结构,运用层次化结构设定测评指标,从而清晰地表述供应链管理成功影响因素测评指标体系的内涵。供应链管理成功影响因素是总的测评目标,为一级指标,即第一层次;供应链管理成功影响因素中的供应链凝聚、区位优势、信息获取能力、信息共享等四大要素为二级指标,即第二层次;根据各要素的含义和内容,将四大要素(二级指标)展开为具体的三级指标,即第三层次。     

Consumer Believability of Information in Direct-to-Consumer (DTC) Advertising of Prescription Drugs

Direct to consumer (DTC) advertising has attracted significant research attention, yet none has focused on empirical assessments of its overall impact on U.S. consumers nationally, and tying assessment to relevant behavioral outcomes. This paper addresses the ethical issue of DTC advertising providing a balance of product and risk information that is both understandable and believable, and contributes direction to those exploring this phenomenon. Richard F. Beltramini is currently Professor of Marketing in the School of Business Administration at Wayne State University. He received his Ph.D. from the University of Texas at Austin, and served on the faculty of Arizona State University for fifteen years. His teaching interests include advertising and marketing management, research, and strategy. His primary research focus is on the believability of marketing communications information, and he has published in the Journal of Advertising, Journal of Advertising Research, Journal of Consumer Research, Journal of Marketing, and a variety of other journals, conference proceedings, and books as well as co-editing Gift Giving: A Research Anthology. Dr. Beltramini has served on the Editorial Review Boards of a number of academic journals, as guest editor of special issues of the Journal of Business Ethics and the International Journal of Internet Marketing and Advertising, as international president of the American Academy of Advertising, as a member of the American Advertising Federation's National Academic Committee and several other professional and business organizations, and is active as a consultant to several international organizations.

Context-Sensitive Access Control Model for Government Services

During the past two decades, e-government information systems have become less paper-based and more computer-based. Those information systems usually take the form of workflow systems. Due to the large social impact of e-government systems, computer security plays a pivotal role in ensuring its efficiency and effectiveness. Access control is one of the key aspects of computer security. Current access control models do not take into account the context of the system and its environment. In this article, we argue that a formal context-sensitive access control model can improve the development of e-government workflow systems and present a particular context-sensitive access control model. The subject of the article is a specification of the context-sensitive access control model for business processes (COBAC). By using a context-sensitive access control, it is possible to define more sophisticated access control policies that cannot be implemented by existing access control models. The COBAC's context is modeled using Web Ontology Language (OWL) in order to provide formal representation of context, rich representation of diverse contextual information, semantic interoperability between various context-aware systems, and a high degree of inference making. The presented model is applicable in different e-government systems, and supports the definition of access control policies for both simple and complex business processes. The model's prototype is verified by a case study on a real e-government business process—the national petty offense trial proceedings.     

The Benefits of IT-Based Supply Chains-Strategic or Operational?

ABSTRACT

Business relationships are being revolutionized by the use of inter-organizational information systems (IOSs) that connect together separate companies' business processes through the application of Information Technology (IT). The physical value chain is now paralleled by the virtual information chain. Detailed case studies from earlier research suggest that there are huge benefits to be gained from concepts such as Electronic Data Interchange (EDI), shared product design databases and shared production scheduling systems. However, there is little empirical evidence of the overall usage and outcomes of IOS implementation. In this survey, IOS benefits are evaluated using marketing derived frameworks. Evidence from 89 United Kingdom (UK)-based organizations, a large proportion of which are trading internationally, suggests that IOSs are becoming pervasive across different business processes and across different types of industry. The analysis reveals that marketing activities are now dominated by the management of the information along the supply chain and that significant benefits can be realized. However, the time-scale for implementing such systems is of the order of 5 to 10 years and there are significant barriers to successful implementation.     

GIS属性信息可视化及其有效性分析

专题地图是GIS属性信息可视化表达的一种重要方式,但存在一个缺陷就是地区面积大小与属性信息的数量差别太大影响读图者的视觉。面域拓扑图是对面状区域分布的专题属性定位表达,对空间区域的形状进行几何变换,使得面积大小与表达的属性信息数量成一定比率关系,将区域内的属性信息映射为面积大小来表达其间的数量差异。通过调查分析,面域拓扑图在表达GIS数量信息时比专题地图具有较好有效性。     

土地督察信息公开的风险影响评价——以专项督察制度为例

研究目的:以专项督察为例,剖析国家土地督察信息公开所带来的社会风险,并借此为优化其公开方式提供借鉴。研究方法:对《国家土地总督察公告》中专项督察公开的案例进行梳理和分析,运用logistic模型分别从土地管理官员和群众的角度分析导致案件公开风险的因素。研究结果:土地督察信息公开的及时性、多样性、互动性和广泛性有待加强,土地专项督察中重大土地违法信息公开的需求与风险并存,且信息公开风险受到公开时间、内容和方式的影响。研究结论:要充分掌握信息公开主动权,加大投入进行土地督察信息公开建设,信息公开前的保密审查机制以及公开后的舆情监测机制亟待建立。     

Assessing the Reliability of Self‐reported Income Information in Informal Small Business Lending through a Bogus Pipeline Experiment

Coping with asymmetric information plays a major role in successful small business lending. Our purpose is to determine if small business applicants report their income information correctly when requesting a loan. We use a randomised controlled trial bogus pipeline experiment, established during a typical cash‐flow analysis of a bank for small businesses in the Philippines. The bogus pipeline approach is commonly applied in social science and aims to increase the rate of truth telling by informing participants that answers will be verified by a lie detector. The experimental data, which include 243 observations of credit clients that are mainly from the agricultural and food value chain, served to identify asymmetric information. Additionally, debtors’ repayment behaviour for approved loans was observed by the bank. Our results indicate that loan applicants of the treatment group report lower incomes, an effect which is most pronounced in lower income quantile. Our analyses also reveal higher loan delinquencies in the control group.     

Knowledge diffusion and agricultural development

Low agricultural productivity remains the primary source of poverty in the developing regions and yet little is known about the influence on agricultural productivity of domestic and international accumulated R&D knowledge and the channels through which this knowledge is transmitted internationally. Following a large scientific literature, this article argues that R&D and R&D knowledge spillover are ecozone‐specific and, therefore, are transmitted internationally through ecozones, where ecozones are the broadest biogeographic division of the earth's land surface. Using data for a panel of 88 countries, it is shown that international knowledge spillovers are ecozone‐specific and have been an important contributing factor behind the marked widening of the income gap between developed and developing countries since 1983.
