Proximity (Mis)perception: Public Awareness of Nuclear,Refinery, and Fracking Sites

Whether on grounds of perceived safety, aesthetics, or overall quality of life, residents may wish to be aware of nearby energy sites such as nuclear reactors, refineries, and fracking wells. Yet people are not always accurate in their impressions of proximity. Indeed, our data show that only 54% of Americans living within 25 miles of a nuclear site say they do, and even fewer fracking-proximal (30%) and refinery-proximal (24%) residents respond accurately. In this article, we analyze factors that could either help people form more accurate perceptions or distort their impressions of proximity. We evaluate these hypotheses using a large national survey sample and corresponding geographic information system (GIS) data. Results show that among those living in close proximity to energy sites, those who perceive greater risk are less likely to report living nearby. Conversely, social contact with employees of these industries increases perceived proximity regardless of actual distance. These relationships are consistent across each site type we examine. Other potential factors—such as local news use—may play a role in proximity perception on a case-by-case basis. Our findings are an important step toward a more generalizable understanding of how the public forms perceptions of proximity to risk sites, showing multiple potential mechanisms of bias.

基于农用地分等成果的大庆市基本农田保护规划研究

以大庆市为例,探讨将农用地分等成果应用于基本农田建设规划设计,为新一轮土地利用总体规划修编提供依据。本文结合大庆市区农用地分等自然等指数、农用地的区位条件和农用地的连片程度,建立逼近于“理想点”的加权排序模型对耕地进行综合排序,按耕地的综合排序顺序应用末级淘汰制遴选基本农田。充分考虑到大庆市区石油产业发展的不确定性特点,结合市区城市发展趋势对初步确定的基本农田保护区进行了两次调整,最终确定基本农田保护率为80．14％,保护规模为112642．2hm2,并应用GIS软件绘制最终的基本农田保护区图。

Is “Walkability” A Useful Concept for Gerontology?

The study tested two hypotheses: that in a walkable neighborhood, residents will exercise more, eat healthier, and suffer from less obesity and that relation between environment and health outcomes will be stronger for the elderly. Health was measured by physical activity, the number of portions of fruits and vegetables eaten daily, and body mass index. Walkability was measured by three distinct environmental factors—distress, amenities, and residential. The three health outcomes were related to the three environmental factors. Age was not a significant predictor of health outcomes. Although the environment does contribute to health outcomes, the ways that contribution is expressed and its relation to age is complex.
