How does the American public assess risk when it comes to national security issues? This paper addresses this question by analyzing variation in citizen probability assessments of the terrorism risk of nuclear power plants. Drawing on the literature on how motivated reasoning, selective information processing, and domain‐specific knowledge influence public opinion, we argue that heterogeneous issue preferences and knowledge of nuclear energy and homeland security have important explanatory power. Using original data from a unique 2009 national survey in the United States, we show that Americans are divided in their probability assessments of the terrorism risk of nuclear power plants. Consistent with our theoretical expectations, individuals who support using nuclear power to meet rising energy demands, who are generally less concerned with terrorism, or who are more knowledgeable about terrorism and nuclear security tend to provide lower assessments of the likelihood that nuclear power plants increase terrorist attacks, and vice versa. The findings have implications for the literature on public opinion, risk assessment, energy policy and planning, and homeland security.  相似文献

Germany and Russia have agreed to build the Nord Stream gas pipeline. The 1,200 kilometers-long structure will run from Vyborg, Russia to Greifswald, Germany traversing the Baltic Sea. The Baltic countries, Finland, Poland and Sweden, have expressed concerns about the project. At issue is the environmental impact of the project as well as the energy, political, and socioeconomic implications.  相似文献

我国从国外引进的合同能源管理是一种推广节省能源新技术的模式,在实际运行中需要协调与整合技术、资金、设施建设与项目管理等多方面的关系,因而,我国对合同能源管理、能源管理合同属性的认识比较模糊,并存在多种看法。为此,必须厘清合同能源管理所涉及的法律关系,充分解析能源管理合同的法律属性,分析把握合同能源管理运营中资产等所有权归属问题,在我国现有法律体系框架范围内,正确、有效地调整合同能源管理关系,积极促进节能新技术在全社会的推广、普及。  相似文献

Bismuth oxychloride (BiOCl) was the first viable synthetic pearl pigment developed 50 years ago. It was only used for a limited time period in automotive paint (model years 1998–2000), serving to produce luster for a single Chrysler black metallic color. Identification of this pigment in an unknown automotive paint can thus facilitate determination of the vehicle of origin. Bismuth oxychloride imparts effects similar to those produced by silver/white mica pearlescent pigments, and such a pigment was used together with bismuth oxychloride in at least one original equipment manufacturer (OEM) basecoat. Silver/white micas are now used primarily in white pearl tricoat systems. This article describes the identification of bismuth oxychloride and silver/white mica pearlescent pigments in automotive finishes using FT‐IR spectroscopy, X‐ray fluorescence (XRF) spectrometry, and SEM/EDS analysis. Data for some cadmium pigments, which were used in automotive paint several decades ago, are also presented as they produce infrared absorptions similar to that of bismuth oxychloride.  相似文献

The study of policy narratives is challenged by inconsistencies and a need for more precise definitions and measurements. The goals of this article are to build precision and clarity in the study of policy narratives by developing a network‐based approach—the ego‐alter dyad—for coding characters and their interactions around a policy issue and then to illustrate this approach in the analysis of air and climate issues in Delhi, India. The empirical results show that (1) the same actors are often heroes and villains, (2) heroes and villains are associated with different actions but with similar victims or beneficiaries, (3) narrators differ in their propensity to tell hero‐heavy or villain‐heavy policy narratives, and (4) the proportion of hero‐heavy or villain‐heavy policy narratives changes over time and differs across subtopics. The article concludes with a research agenda for further theoretical and methodological advancement in studying policy narratives.  相似文献

Debates abound regarding the link between trade and industrial policy and the adoption of sustainable energy technologies in developing countries. Some purport that open trade regimes support technology diffusion, while others indicate that more interventionist regimes are more conducive. This paper uses empirical evidence from Mexico City and São Paulo to argue that sustainable energy technology uptake can be more prevalent in settings with partially open trade policy regimes. These regimes have afforded countries more opportunities to develop local capabilities, which, in turn, has had knock‐on effects on sustainable energy technology uptake. Specifically, having more local technology sources (equipment, expertise) brought quicker access to these technologies, created more perceptions of technology “ownership,” fostered more effective mobilization, and helped create well‐established standards, which in turn contributed positively to sustainable energy technology uptake, while taxes and tariffs were less influential.  相似文献

Concerns over the toxic by‐products produced by traditional ammunition have led to an increase in popularity of nontoxic ammunition. In this work, the chemical composition of six brands of nontoxic ammunition was investigated and compared to that of a road flare, which served as an environmental source with similar composition. Five rounds of each brand were fired while a further five were disassembled and the primer alone was fired. Particles collected from all samples, including the road flare, were analyzed by scanning electron microscopy with energy dispersive X‐ray analysis. Common elements among the different ammunition brands included aluminum, potassium, silicon, calcium, and strontium. Spectra were then subjected to principal components analysis in which association of the primer to the intact ammunition sample was generally possible, with distinction among brands and from the road flare sample. Further, PCA loadings plots indicated the elements responsible for the association and discrimination observed.  相似文献

目的探讨致命室性快速型心律失常(LVTA)能量代谢相关变化及氧化损伤。方法建立以乌头碱(ACO)注射和冠脉结扎(CAL)心肌缺血诱导的LVTA-心脏性猝死(SCD)SD大鼠模型,以过度麻醉(PI)及冠脉结扎心衰致死(CAL-B)为各自对照,检测心室肌线粒体膜电位(MMP)、活性氧(ROS)、丙二醛(MDA)、磷酸肌酸(PCr)及血清肌钙蛋白I(cTnI)含量,并进行比较。结果成功制备ACO-LVTA及CAL-LVTA大鼠14只及6只。与各自的同行对照比较,ACO-LVTA组及CAL-LVTA组心室肌的ROS及MDA呈升高的趋势,PCr呈下降的趋势,其中CAL-LTVA的MDA显著高于其同行对照(P0.05)。ACO-LVTA组心室肌的MMP低于对照组,但高于CAL处理的两组。CAL-LVTA组血清cTnI高于对照组,且显著高于ACO-LVTA组及其对照与处理前(P0.01),ACO-LVTA组血清cTnI高于对照组与处理前。心肌ROS水平与VT及VF持续时间相关(P0.05),相关系数分别为0.44、0.46。结论发生LVTA后,心室肌MMP及PCr下降、ROS、MDA升高,血清cTnI升高,表明LVTA可导致能量代谢改变及氧化损伤,可能与线粒体功能异常相关。  相似文献
