Design and evaluation of road pricing: state-of-the-art and methodological advances

This article provides an in-depth review of the state-of-the-art and describes methodological advances in the design and evaluation of road network pricing schemes. A number of paradigm shifts from the two polar cases of the marginal social cost pricing of road traffic congestion and revenue-maximizing road toll pricing are analyzed, as induced by the need to address realistic design complexities and constraints. The crucial role of the joint consideration of pricing strategies with optimal capacity provision and several network management measures is manifested and an integrated evaluation framework is suggested to incorporate a wide range of road pricing impacts into the scheme design process.

浅议现阶段财务人员绩效考核

财务人员是每个企业、事业单位的重要成员,是不可缺失的岗位,在每个单位中起到核心地位.现阶段各个企业、事业对本单位内部的员工进行绩效管理,财务人员的绩效考核便随之诞生.企业要正确认识对财务人员现阶段的绩效考核指标是否正确、是否适应公司的现状,企业要重视公司财务人员的绩效考核.     

工程建设项目评标方法综述

目前国内工程建设项目中关于编制评标方法需要遵循的法律、法令较多,除了招标投标法之外,国家各部委、地方也分别颁布了许多关于详细操作的具体文件规定.如何在不违反各项法律、法规、法令的前提下顺利按时完成招标采购任务,是摆在所有工程建设招标采购人员面前的一项难题.     

SYSMIN: An evaluation

The Third Lomé Trade and Co-operation Convention between the European Community and the African, Caribbean and Pacific (ACP) countries was signed on 8th December 1984. It is valid for the period from 1.3. 1985 to 28.2. 1990 and incorporates an extension of SYSMIN, the special financing facility for mining products created five years earlier under Lomé II. Now that Lomé III has passed its mid-term it is time to take stock of what SYSMIN has achieved and to begin thinking about improvements to be negotiated for Lomé IV.

The evaluation of time-dependent attributes

This study investigated time-dependent attributes; that is, those not known during use but where the passage of time reveals information about the attribute. In a lab experiment, subjects were asked to try out a new home banking system. Two independent variables were manipulated: (a) the accuracy (or inaccuracy) of a bank transaction, and (b) whether the information about accuracy was revealed immediately or after a delay. An unknown time-dependent attribute (i.e., accuracy of fee charges) was evaluated more favorably when a highly correlated attribute, transaction accuracy, was also evaluated positively. When the attributes were not highly correlated, there was an interactive effect of information about transaction accuracy and the time when this information was revealed on evaluations of time-dependent attributes. Generally, information that was received with delay influenced the evaluation of time-dependent attributes, but information received immediately did not. © 1996 John Wiley & Sons, Inc.     

Consumer evaluation of recycled products

Despite the tremendous growth of recycled and recyclable products in recent years, there exists very little research on how consumers evaluate such products. An experiment was conducted to examine whether consumers' reactions to recycled products is product specific and cognitive or affective and not product specific. Results indicated that consumers are favorably influenced by the presence of recycled material regardless of the type of product, thus supporting an affective evaluation process. Results also indicated that the positive effects of recycling held only for established brands and not for new brands. © 1995 John Wiley & Sons, Inc.

Further evaluation of conglomerate performance

In the early years conglomerates were seen as the financial concept of the future. More recently their economic advantages have been seriously questioned. This article reviews the existing literature on conglomerate performance and extends the investigation through the early seventies. While conglomerates provide investors with less variability from market movements than do nonconglomerate firms, they provide less diversification than closed-end investment companies and mutual funds. Furthermore, risk adjusted performance measures of conglomerates did not differ significantly from those of other firms of portfolios. Thus, conglomerates should be viewed simply as another category of investments that plot along the security market line.
