Speed reduction measures rank among the most common schemes to improve traffic safety. Recently many urban streets or entire districts were converted into 30 kph zones and in many European countries the maximum permissible speed of trucks on motorways is under discussion. However, besides contributing to traffic safety, reducing the maximum speed is also seen as beneficial to the environment due to the associated reduced fuel consumption and lower emissions. These claims however are often unsubstantiated.To gain greater insight into the impact of speed management policies on emissions, this paper examines the impact on different traffic types (urban versus highway traffic) with different modelling approaches (microscopic versus macroscopic). Emissions were calculated for specific types of vehicles with the microscopic VeTESS-tool using real-world driving cycles and compared with the results obtained using generalized Copert-like macroscopic methodologies. We analyzed the relative change in pollutants emitted before and after the implementation of a speed reduction measure for passenger cars on local roads (50–30 kph) and trucks on motorways (90–80 kph). Results indicate that emissions of most classic pollutants for the research undertaken do not rise or fall dramatically. For the passenger cars both methods indicate only minor changes to the emissions of NOx and CO2. For PM, the macroscopic approach predicts a moderate increase in emissions whereas microscopic results indicate a significant decrease. The effects of specific speed reduction schemes on PM emissions from trucks are ambiguous but lower maximums speed for trucks consistently result in lower emissions of CO2 and lower fuel consumption. These results illustrate the scientific uncertainties that policy makers face when considering the implementation of speed management policies. 相似文献

This study indicates that schools of business influence the personal values of their students. Current management education produces individuals who have ego-centered rather than society or other-centered values. Given this framework the authors raise the question, “Do business schools produce the type of manager that is needed in the future?” 相似文献

Vulnerable consumers are at particular risk of financial detriment due to, for example, low financial literacy or numeracy, high debt, low income, or impactful changes in personal circumstances. We introduce a comprehensive and formative measure of financial vulnerability that integrates these risk factors and is grounded in definitions of vulnerability from financial regulation bodies and government agencies such as the Consumer Financial Protection Bureau. Across three studies of US individuals, we assess the nomological validity of this measure of financial vulnerability through its relationship with positive and negative financial outcomes (e.g., savings levels, paying credit card balances in full each month, being in arrears) as well as relevant psychological characteristics (e.g., personal savings orientation [PSO], money management skills, financial self‐efficacy). Moreover, we examine whether and how these psychological characteristics mediate the relationship between financial vulnerability and financial outcomes. We conclude with an overview of implications for policy makers and business practitioners. 相似文献

Innovation in financial markets, spurred to a significant extentby developments in finance theory and financial econometrics,has played a critical role in spurring economic growth. However,the current turmoil in financial markets raises fundamentalquestions about the nature of financial innovation and the roleof policymakers in maintaining financial stability. This paperexplores these questions, focusing on the complexities of modelingfinancial risk and the potential trade-off between policiesaimed at combating short-run financial instability on the onehand and the potential financial market distortions and moralhazard that can result from such policies on the other. 相似文献

We argue that the computerized information system should not look like a system on its own. Rather, it should be conceived as an inherent part of the work of its users. We therefore introduce the concept of an embedded system, which describes work tasks and organization. Computer‐supported information tasks are embedded in this environment: They are not parts of a system separated from other activities. This concept is based on the experiences gained during the development of a user‐interface prototype, derived from a theoretical frame of reference, called act orientation, to information systems, in which all computerized tasks are interpreted as acts performed by the actual user. Our suggestion continues the tradition of on‐line help and support, reaching radically deeper than usual in related approaches. We expect that our suggestion will, when applied, improve the control, productivity, quality of the outcome of work, and quality of working life, assessed from the user's point of view. 相似文献
