“I live with terror inside me”: Exploring customers’ instinctive reactions to terror

Terrorist attacks occur mostly at public service-oriented sites. Consequently, their victims are likely to be customers. The present study explores how customers instinctively react toward the reality of terror in a matrix of 2 × 2 aspects concerning terror circumstances: temporal proximity (brief or long) and physical proximity (close or remote) from the terror event. In qualitative in-depth interviews, customers from France and Israel were requested to share their instinctive reactions and coping strategies when approaching hospitality (hedonistic) and transportation (utilitarian) services. Participants (N = 47) comprised customers having a protracted acquaintance with persistent terror threats. The analysis identified differences in reactions, subject to temporal and physical proximities. When terror attacks are physically close, customers’ emotions, cognitions, and behaviors undergo modification with time. However, when terror attacks occur at a location remote from the customer, customers’ emotions and cognitions, but not their behavior, change with time. These reactions were comparable for the two service contexts. Practical implications were elaborated to enable service establishments (i.e., hospitality and transportation) to design and manage their operations for the short and long term to assist customers in the difficult era of terror.     

Are USDA reports still news to changing crop markets?

This study investigates whether major USDA reports still provide important news to changing crop markets. The news component of each report, or market “surprise,” is measured as a difference between the USDA estimate and its private expectation in corn, soybeans, and wheat markets. Changes in the relevance of USDA information are assessed by examining changes in the magnitude of market surprises and shifts in the futures price reaction to these surprises, which isolates the impact of each report. The stable size of market surprises over time suggests that competition from alternative data sources has not reduced the news component of USDA crop reports. Increasing price reaction to most reports, including those facing competition from alternative information sources, suggests that value of public information may be enhanced in uncertain markets affected by structural changes.     

The equity impacts of bus rapid transit: A review of the evidence and implications for sustainable transport

The paper offers an analysis of empirical evidence on the equity impacts of operational Bus Rapid Transit (BRT) systems in the Global South. The focus is on vertical equity, i.e. whether BRT systems achieve progressive benefits for poorer segments of the population. Findings from Africa, Asia, and Latin America all suggest that BRT does offer significant benefits to low-income groups, in terms of travel time and cost savings, access enhancement, and safety and health benefits. However benefits are often skewed toward medium-income users and thus less progressive than they might be. Two primary reasons for this are insufficient spatial coverage and inappropriate fare policies. While many features of BRT potentially allow it to deliver pro-poor outcomes, such outcomes only materialize if BRT implementers pay specific and sustained attention to equity. The paper identifies key issues that need to be addressed to steer BRT implementation toward more socially sustainable outcomes—including better integration with other transit, paratransit, and nonmotorized transport services, and with the housing sector.

活性污泥法降解苯酚模拟废水的动力学研究

研究了活性污泥法降解苯酚模拟废水的动力学规律。实验结果表明，活性污泥法对苯酚废水具有良好的降解性能，正常状态下，3h内COD去除率迭90％以上。降解过程符合一级反应动力学方程。不同污泥浓度时反应速率常数K1相差不大，提高苯酚初始浓度K1亦增大。pH值在4．8-9．1范围内，活性污泥保持良好的降解性能，pH值过大或过小时，微生物均受到抑制。在15-35℃，K-随温度的升高而增大，求得温度系数θ为1．054。

基金业绩、基金经理更换与投资者财富效应——一项基于我国资本市场的实证研究

从基金管理公司内部的委托—代理关系出发,以封闭式基金为研究对象,从基金经理调整现状、基金业绩与基金经理调整的关系、基金经理调整公告的市场反应三个方面,对基金经理变动进行了实证分析。研究发现:基金业绩确实对基金经理更换及更换后的去向具有一定的参考价值,但基金经理更换并没有使更换经理后的基金业绩显著改善;基金经理公告确实引起了基金市场价格的变动,但没有使基金投资者的财富显著增加。     

中部省份在国家经济发展战略西移中崛起的若干思考

国家经济发展战略西移将对我国区域经济发展格局产生非常显著的影响。对中部省份而言，机遇与挑战并存。中部省份在全国经济发展中所处的地位、全国性的经济技术转移、地区产业结构调整与升级要求等，使得中部省份有条件在国家经济发展战略西移过程中迅速崛起。中部省份必须营造良好的发展环境，加快基础设施建设，积极调整产业结构，选择培育经济发展极，调整与完善各项政策，积极探索区域经济合作的新模式等，以实现中部与西部地区的共同发展。
