Modern printing toners represent a prime example of subvisible particles that can be easily transferred to hands, clothing, and other surfaces. To explore the potential evidentiary value of toner particles, toner samples were collected from known printer cartridges and characterized by various microanalytical techniques to establish the properties most useful for recognition, identification, and comparison. Environmental samples (i.e., dust) were then collected from various locations at varying distances from toner-based printers, using both tape lifts and carbon adhesive stubs, to assess the possibility of detecting toner. By light microscopy, toner can be recognized on the basis of particle size and shape, as well as color. Further examination of the micromorphology in the field emission scanning electron microscope reveals characteristic morphologies and differences in surface texture and shape among toner sources. Raman spectroscopy provides chemical identification of the pigment (or pigment class) and, in some cases, also permits identification of the polymer component. While black and blue pigment chemistry remained constant among toner varieties that were studied (copper phthalocyanine and carbon black), variation in yellow and magenta pigments was observed. Analysis of dust samples collected from various environments demonstrated that while toner is consistently detectable in close proximity to printers (within 2 feet), it also can be detected in dust collected in nearby rooms. This research demonstrates that toner particles can be located, characterized, and discriminated, using a suite of microanalytical methods that are applicable to forensic casework.  相似文献

Our article explores the contribution of local initiatives to the creation of path dependencies for energy transition in Germany and Japan in the face of resistance from entrenched incumbents at the national level. We use a process‐tracing methodology based partly on interviews with local participants. In particular, we explore the role of local initiatives in securing “socio‐political space” for the expansion of renewable energy (RE) and in embedding themselves in “ecosystems” of public and private institutions. German energy activists were more successful than their Japanese counterparts in expanding this space and creating positive feedback in part because they were able to build horizontal networks that anchored the energy transition firmly in local communities. Although problems with grid technology have led to retrenchment in both cases, Japanese activists' reliance on vertical networks has limited their ability to weather a backlash from national government and utility actors. Our study demonstrates the interaction of political, economic/technological, and legitimation paths to energy transition and highlights the importance of the latter two.  相似文献

古典经济学认为,能源大规模出口的财富效应有助于推动出口国的经济增长,然而20世纪70年代以来世界主要能源出口国经济增长普遍放缓甚至停滞的残酷现实表明,丰富的能源很可能并非推动经济增长的"祝福",而是拖累经济的"诅咒"。为了探讨诱使能源出口国陷入"能源诅咒"的原因及其作用机制,本文基于产业联盟理论建立了涵盖能源出口国现代化起点、政体类型、出口条件的分析框架,重点分析上述三个因素对能源产业联盟实力强弱的影响。通过对能源出口国主要政治与经济数据的定量分析以及对委内瑞拉和俄罗斯陷入"能源诅咒"的案例研究,本文发现,能源出口国的现代化起点较晚、实行威权政体、出口条件改善催生了强大的能源产业联盟,并巩固和扩大了其相较于其他产业联盟的实力差距。强大的能源产业联盟贡献了巨额税汇、提供了畸形补贴、左右了选举结果,由此诱使政府与政治家对其形成了病态的依赖,限制了其他产业的发展并最终拖累了经济增长。  相似文献

Energy transitions are fiercely contested. The incumbents of the fossil‐ and nuclear‐based energy systems have much to lose from a transition to a sustainable and decentralized energy system. They therefore employ their material and political resources to reverse, halt, or slow down this transition. They also attempt to stop and reverse the decentralization of energy production. This article provides a framework that can be used to analyze the contestation that surrounds energy transitions. The analytical framework breaks apart the macro paths of energy transitions, and differentiates between three meso‐paths (political, economic‐technological, and legitimation), emphasizes the feedback processes between these paths, and acknowledges the crucial role that actors play in engendering these feedback processes. It uses Germany as a case study to illustrate the analytical model. It also provides hypotheses that will be tested in the subsequent contributions to this special issue.  相似文献

Today, Northeast Asia’s security situation is changing rapidly. North Korea is reviving and China’s power is growing at an alarming rate. While the U.S. continues to suffer diplomatically and militarily in the Middle East and from international terrorism, China’s and North Korea’s power is likely to futher increase, polarizing the Northeast Asian security structure, with South Korea, Japan (and Taiwan) all allied with the U.S. versus North Korea allied with China. The liberal democracies should pursue peace with North Korea and China to preclude the situation from aggravating, but should be ready in the longer term to meet, in diverse ways including strengthening their alliances, the challenges posed by rising powers.

Over the past three decades, various power sector reforms have overhauled the governance of electricity generation, transmission, and distribution in almost a hundred countries. Have these reforms produced benefits? Using instrumental variables, we improve upon earlier studies and demonstrate that power sector reforms enacted between 1982 and 2008 have both had large positive effects on the availability of generation capacity and reduced transmission and distribution losses. We also show that the positive effects on generation capacity are pronounced in developing countries and that hybrid reforms falling short of privatization and free competition are effective in improving generation capacity in particular. Overall, the results show that these reforms are an effective tool to remove an important constraint on economic growth.  相似文献

New York municipalities passed more than 60 measures promoting high‐volume hydraulic fracturing (HVHF), 2008–12. These policies and resolutions signaled to state officials that municipalities desired HVHF's promised economic benefits and were anxious for an end to the state's HVHF moratorium. They also may be evidence of municipalities proactively preparing for a drilling boom. Why did some jurisdictions adopt these measures while others did not? While scholarship suggests that policy adoption is facilitated when jurisdictions and citizens possess more resources, capacity appears to have a negative or negligible impact on pro‐HVHF action. Such action appears more likely when local actors anticipate HVHF's potential gains but have not previously experienced substantial drilling, perceive that the industry could be viable locally, and can access relevant policy examples. Some lessons from conventional adoption scholarship may not apply when policies are symbolic, advocacy may be elite‐driven, and mimicry is an important diffusion mechanism.  相似文献

In the UK, local authorities (LAs) have been placed at the forefront of domestic energy-reduction strategies as the responsible actors for coordinating policy in this sector. Yet, there has been little research regarding the role of LAs in this policy agenda, and their abilities to bring together stakeholders in the successful design and implementation of strategies to reduce energy demands. The paper aims to fill this gap by highlighting the relevance and importance of the energy policy sphere to local government studies, building on the idea of resilient LAs within the context of tensions between the localism agenda and the actual implementation of energy efficiency polices. This is achieved through multiple rounds of semi-structured interviews with LA officers. Our findings reveal that LAs, operating under a localism agenda, lack the freedoms and resources from central government to meet the needs of multiple stakeholders, resorting to short-term policies.  相似文献
