State legislative decision making on natural gas policy has become a balancing act, as legislators are forced to grapple with tensions between economically beneficial policies and environmental impacts. Despite increased public attention to the benefits and costs related to hydraulic fracturing, there has been little scholarly attention paid to how policy framing affects legislator behavior on this issue. We analyze recorded votes on bills relating to natural gas policy in Wyoming, Colorado, and New Mexico between 1999 and 2008; a time period spanning the recent boom. Using a novel database of bill frames, we create a ratio measure that accounts for the proportion of environmental to economic arguments within each piece of legislation. We find status quo–challenging, anti‐development policies can receive bipartisan support, as long as economic frames balance or are greater than environmental frames. Framing natural gas as a win‐win scenario where economic benefit and environmental protection can be achieved simultaneously is an effective legislative strategy. Using the case of natural gas policy, this study demonstrates bill framing substantively affects state legislator vote choice and implies bipartisan compromise is possible given the right balance of frames.  相似文献

The adsorption onto other minerals of charged gold nanoparticles, carried by gas ascending from the Earth’s interior, is an important component of their transport and deposition in surficial cover such as alluvial, aeolian, and glacial sediments. To simulate the adsorption of these particles, an experiment was conducted in which a flow of air that contained gold nanoparticles was passed upward through a sample of alluvium from the middle–lower reaches of the Yangtze River. These experiments showed that gold nanoparticles are adsorbed on kaolinite, halloysite, goethite, and hematite in the alluvial cover. Both the gold nanoparticles and minerals (i.e., kaolinite, halloysite, goethite, and hematite) carry surface charges that provide them with excellent adsorption properties. This study showed that the specific mineral composition of surficial alluvial cover affects the concentration of gold nanoparticles in the ascending gas. This phenomenon may plausibly be used in exploration for concealed gold, copper–gold, and silver–gold deposits in areas of thick alluvial cover. Geofluids (2010) 10 , 438–446  相似文献

Continuous mud gas loggings during drilling as well as offline mud gas sampling are standard procedures in oil and gas operations, where they are used to test reservoir rocks for hydrocarbons while drilling. Our research group has developed real‐time mud gas monitoring techniques for scientific drilling in non‐hydrocarbon formations mainly to sample and study the composition of crustal gases. We describe in detail this technique and provide examples for the evaluation of the continuous gas logs, which are not always easy to interpret. Hydrocarbons, helium, radon and with limitations carbon dioxide and hydrogen are the most suitable gases for the detection of fluid‐bearing horizons, shear zones, open fractures, sections of enhanced permeability and permafrost methane hydrate occurrences. Off‐site isotope studies on mud gas samples helped reveal the origin and evolution of deep‐seated crustal fluids.  相似文献

At Ocean Drilling Program Site 997 in Blake Ridge gas‐hydrate field in West Atlantic, pore‐water studies revealed a pronounced downward depletion of the heavy chlorine isotope to nearly ?4‰δ37Cl at approximately 750 m below sea floor (mbsf) associated with a 10% downward chlorinity decrease. This is one of the stronger 37Cl depletions hitherto reported for marine pore waters. Chlorinity reductions in hydrate‐bearing sediments commonly result from fresh‐water release by hydrate melting. However, in situ measurements at Site 997 suggest that >50% of the chlorinity reduction occurred prior to hydrate dissociation. Modeling the chlorinity profile shows that advection of a strongly 37Cl‐depleted, low‐chlorinity water (506 mm ) from below the drilled sequence can explain the reduction prior to sampling. Fitting the model to the δ37Cl curve yielded an advection rate of 0.18 mm year?1. Diffusive mixing with near‐0‰‐δ37Cl paleo‐seawater with maximum chlorinity at shallow subsurface depths (561 mm at approximately 20 mbsf) produced the smooth, steady trend. Separating that part of the freshening caused by advection and diffusion from that due to hydrate dissociation allowed estimation of average hydrate concentrations of 3.8% of the pore space (up to 24.5% in hydrate‐rich layers; near‐100% in rare massive hydrate layers). The deep‐seated source of the 37Cl‐depleted, low‐chlorinity water remains unknown and might be located below the sedimentary section in the oceanic basement.  相似文献

?Exotic Bodies”?: Russian Anthropology and Medicine in the Colonial Discours of Late Imperial Russia. In the nineteenth century Russian anthropologists adopted Western theories on the biological superiority of the white man in order to justify Russian colonization at the Asiatic periphery. After the Great Reforms the imperial process of acculturation was discussed in the context of modernization that also touched the institutionalization of colonial medicine. Whereas Russian armchair anthropologists were operating with racial idioms, physicians as practitioners on the colonial spot were not receptive to the ideology of “white man's burden”. From experience with the socioeconomic backwardness of Russia's Asiatic periphery physicians stood up for the vital rights of the indigenous population in the colonial Public Health. With deep respect for indigenous medicine Russian physicians were not advocates of Russian colonial expansion and racial discrimination that made them different to their Western colleagues. On the basis of Russian nineteenth century medical literature and Siberian archival sources this paper outlines the critical reflections of Russian physicians on Tsarist colonialism  相似文献

Written sources and iconographic evidence suggest that honey and beehive products, used in culinary, medicinal, and technological functions since pre-Neolithic times, were likely known and used in Phoenician and Punic Sardinia. The role of these resources is nonetheless poorly understood because no direct evidence survives on a macroscopic level. Significant advances in the knowledge about beeswax and beehive products processing in the past have been offered in recent decades by organic residue analyses (ORA), an approach that enables the characterisation of surviving chemical compounds or suites of compounds that provide information relating to human activity in the past. The relatively recalcitrant nature of lipid compounds comprising beeswax means that this commodity is among the products that can be unambiguously identified through ORA. Here we present and discuss the results of analyses undertaken on 368 pottery sherds from Phoenician and Punic Sardinia (eighth to third century BCE). These analyses offer direct evidence for the presence of beehive products on the island, suggesting the use of honey for culinary purposes in pots, and possibly connecting one specific vessel category with beeswax decanting during beekeeping and honey production processes. Our results also now clearly illustrate the widespread use of beehive products in pre-Roman Sardinia.  相似文献

The roots of Russia's invasion of Ukraine are to be found in two areas. The first is the revival of Tsarist imperial nationalist and White Russian émigré nationalist denials of the existence of Ukraine and Ukrainians. Russian imperial nationalists believe the eastern Slavs constitute a pan Russian nation of Great Russians, Little Russians and White Russian branches of one Russian nation. The second is the cult of the Great Patriotic War and Joseph Stalin and the revival of Soviet era discourse on Ukrainian Nazis (i.e., nationalists). A Ukrainian nationalist in the Soviet Union and Vladimir Putin's Russia is any Ukrainian who seeks a future for his/her country outside the Union of Soviet Socialist Republics and Russian World and who upholds an ethnic Ukrainian (rather than a Little Russian) identity. The Russian World is the new core of the Eurasian Economic Union, Russian President Vladimir Putin's alternative to the EU's Eastern Partnership. In the contemporary domain, Ukrainian nationalists are Nazi's irrespective of their language preference or political beliefs and if they do not accept they are Little Russians. Putin's invasion goal of denazification is a genocidal goal to eradicate the ‘anti-Russia’ that has allegedly been nurtured by Ukrainian nationalists and the West.  相似文献

A review of zooarchaeological research is presented for one of the best-studied areas of the Russian Far East, Primorye (Maritime) Province. The faunal remains, including mammals, birds and fish, were derived from archaeological contexts ranging from the Upper Palaeolithic, ca. 33 000 years ago, to the Middle Ages, twelfth to thirteenth centuries AD . Among the wild species, hoofed animals, wild boar, and bears are the most common. Domesticated animals are represented mostly by pig and dog. At the Pleistocene–Holocene boundary, ca. 10 000–12 000 years ago, some species, such as mammoth, woolly rhinoceros and bison, became extinct. Since the Middle Holocene, ca. 7000 years ago, the faunal complexes became of modern composition. The finding of bones of domesticated animals in the Bronze Age, dated ca. 2800–3200 years ago, allows the correlation of the emergence of livestock in Primorye with cultural influences from northern China. © 1997 by John Wiley & Sons, Ltd.

This article examines the global travels and anti-colonial thought of the Indian revolutionary Manabendra Nath Roy. It focuses particularly on his little explored stay in revolutionary Mexico, where he became a founder of the Mexican Communist Party in 1919. Drawing on archival sources from various countries and Roy's own writings, the article situates Roy's exploits somewhere between a global anti-colonialism, transnational solidarity and diasporic nationalism. It explores particularly the possibilities and the limits of an image of Asia and Latin America as regions united in their oppression by imperialism, and warranting shared anti-colonial strategies in the framework of international Communism.  相似文献

This article explains the crystallisation of a new Russian national discourse, shaped by a challenge posed to Putin's statist non‐ethnic national model by a popularly formed ethno‐cultural alternative, constructed through negation of the ‘Muslim other’. The article describes this new and previously overlooked phenomenon of Russian nationalism and explicates the social mechanism behind its formation. The article concludes that when rampant corruption exists, generating a breakdown of legal order, the ‘other’ is defined through behaviour that deviates from accepted local norms, while the contrasting normative ‘general public’ is defined as ‘Russian’. Such group definitions mean that the current process of Russian grass‐roots exclusive national consolidation is based predominantly on culturally based behavioural codes, rather than on mere ethnic or religious affiliation, as is widely believed. Additionally, a conceptual landmark discourse shift from the question of Russia's mere plausibility as a nation‐state to a focus on its ongoing definition is demonstrated.  相似文献
