工频电磁场对公众健康及风险感受影响调查

为调查工频电磁场对附近居民健康及风险感受的影响,对16条已投运110~500kV输电线两侧居民(n=615)开展问卷调查,根据输电线运行参数计算工频电磁场相对曝露强度,分析了工频电磁场对距线路中心50m内、外受调查者产生的健康影响差异,以及不同工频电磁场曝露强度、电压等级、塔型附近受调查者风险感受和负面情绪的均值差异,并通过多元线性逐步回归分析分别建立了工频电磁场公众风险感受、负面情绪与影响因素之间的最优回归模型.结果表明,工频电磁场对50m内和50m外受调查者产生健康影响的相对风险值为0.87;在本次调查的工频电磁场范围内(E<0.35kV/m,B<0.80 μT),公众风险感受和负面情绪受工频电磁场曝露强度影响很小,受输电线架线塔外观大小、塔型、既有身体状况等因素影响显著.     

A critique on neuroscientific methodologies in organizational behavior and management studies

Organizational neuroscience continues to flourish in organizational behavior and management studies as indicated by the growing number of publications. However, with a few exceptions, substantive critiques of organizational neuroscience are conspicuous by their absence. In this point–counterpoint article, we aim to redress this imbalance. We do so by asking two significant yet neglected questions: (i) how strong is the science behind this domain, and (ii) why are we doing this type of research (the so what? question)? Our analysis shows that the science behind organizational neuroscience is far less rigorous than currently advocated (due to low statistical power of some neuroimaging studies plus an inability to locate mental phenomena precisely in the brain). In terms of the so what? question, we encourage researchers to move away from general statements and become more specific about the phenomena they research. We contend that the practical implications of this research, as well as inferences of the link to behavioral changes, are currently overstated. We also underscore the importance for these studies to become contextually sensitive in order for the researchers to capture important events in the workplace. Finally, we offer some suggestions for future research. Copyright © 2014 John Wiley & Sons, Ltd.     

A system design framework for the integration of public preferences into the design of large infrastructure projects

Large infrastructure projects such as new roads, railways and nuclear plants have often suffered from public opposition, causing significant delays and costs. In many cases poor engagement between the supporters of construction and the public have contributed to this. Therefore, this paper proposes a novel design framework with the aim of improving public engagement at an early design stage. Following a modified quality function deployment (QFD) process, it enables incorporation of public preferences into the design process, thus helping to improve the social acceptability of large infrastructure projects and reduce costs related to opposition and delays. The application of the framework is illustrated by a case study related to design of nuclear power plants.
