This paper analyzes the determinants of Chinese government support for methanol automobile fuel development. At the national level, a preference for low carbon alternatives, ongoing bureaucratic restructuring, and profitability concerns of the national oil companies (NOCs) help to explain a lack of support for methanol fuel. At the local level, a short-term and localized view of industry development explains why some governments actively promote methanol fuel through local standardization, subsidies, and management of NOC opposition. The case of methanol fuel illustrates how local governments with strong, embedded interests have filled in the national-level policy vacuum on this issue. These findings contribute to the ongoing debate on the evolving central–local relations in China and hold lessons for alternative fuel adoption efforts underway in many parts of the world.  相似文献

The conflicting interests that underlie globalization can be difficult to grasp in a traditional classroom setting. The simulation presented here challenges students to examine the many different actors operating in the international system today. The focus is the Chad–Cameroon oil pipeline—a landmark example of cooperation and conflict between international institutions, non-governmental organizations and business interests. Given a scenario, students assume these roles and negotiate for the continued success of the pipeline. All the materials to run this exercise are included and if utilized, can provide a positive active learning experience.  相似文献

This study involved the comparative analysis and discrimination of 964 architectural paint samples collected in the United States and Canada. The samples were evaluated to determine the extent to which randomly collected architectural finishes can be discriminated following standard operating protocols for paint analysis. The study also provides a basis for assessing the significance of a result in which a pair or group are undifferentiated. The techniques utilized were stereomicroscopy, Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) with both backscatter electron imaging (BSI) and energy dispersive spectroscopy (EDS), and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). To assess the layer characteristics (e.g., number, color, sequence, thickness), stereomicroscopy was used with FTIR and/or SEM as needed. The use of visual and microscopic evaluations in concert with FTIR resulted in 42 undifferentiated pairs, a discrimination of 99.99%. Adding SEM and Py-GC/MS analysis resulted in further discrimination of 31 pairs, resulting in eleven undiscriminated pairs of samples. At the conclusion of the study, samples that remained undifferentiated proved to originate from the same source. Therefore, no random pairs were indistinguishable at the conclusion of all examinations.  相似文献

Past research suggests that spouses influence one another to vote, but it relies almost exclusively on correlation in turnout. It is therefore difficult to establish whether spouses mobilize each other or tend to marry similar others. Here, we test the dependency hypothesis by examining voting behavior before and after the death of a spouse. We link nearly six million California voter records to Social Security death records and use both coarsened exact matching and multiple cohort comparison to estimate the effects of spousal loss. The results show that after turnout rates stabilize, widowed individuals vote nine percentage points fewer than they would had their spouse still been living; the results also suggest that this change may persist indefinitely. Variations in this “widowhood effect” on voting support a social‐isolation explanation for the drop in turnout.  相似文献

The past year has seen a steady rise in tensions with regard to Iran's nuclear programme. Iran's economy is being crippled by far-ranging sanctions and the threat of an Israeli attack on Iranian nuclear facilities looms large on the horizon. Yet the country's nuclear programme marches on, stoking fears that Iran may indeed be seeking to cross the nuclear weapons threshold. In this context, it is timely to consider how key regional players would respond to a nuclear-armed Iran. Many argue that an Iranian bomb would prompt a proliferation cascade in the Middle East. However, a closer examination of the drivers for key regional players shows that this is not necessarily the case. There is a range of non-proliferation tools that could be applied by the West and others to offset this risk.  相似文献
