Stable carbon (δ13C) and nitrogen (δ15N) isotope analyses of dog (Canis familiaris), island fox (Urocyon littoralis), and human bone collagen from CA-SRI-2 (AD 130–1830) on Santa Rosa Island, California provide a proxy of diet and the relationships between humans and these animals. Carbon isotopic signatures indicate that Native Americans and their dogs at CA-SRI-2 subsisted almost exclusively on marine resources, while the island fox ate primarily terrestrial foods. Nitrogen isotopes and archaeofaunal remains indicate that humans and dogs also ate higher trophic level foods, including finfishes, marine mammals, and seabirds with smaller amounts of shellfish. The CA-SRI-2 island foxes appear to have eaten higher amounts of terrestrial foods, similar to the diets observed in modern fox populations. These data generally confirm the commensal relationship assumed to exist between domesticated dogs and people, but the carbon isotopic composition of dogs is enriched ∼2‰ compared to humans. We hypothesize that the difference in carbon isotopes between dogs and humans may have resulted from a higher consumption of C3 plants with lower δ13C values by humans, or less likely from the ingestion by dogs of significant amounts of bone collagen, which is enriched by ∼4‰ over associated muscle.  相似文献

This review article documents and analyzes trends within the environmental policy literature published between 2014 and 2017. We find that environmental policy scholarship has recently shifted its focus from more traditional topics, such as watershed and ecosystem management, to other modern issues, such as climate change and energy. The environmental policy literature has increased in complexity and become more interdisciplinary in nature, which we illustrate with a discussion of the energy justice literature. The methodological approaches used by environmental policy scholars have also become increasingly diverse, with a notable uptick in statistical and modeling approaches. We find that some topics, such as policy failure, gender issues, and energy welfare policies are under‐explored, and certain regions within the world, such as developing countries, are less frequently studied. We encourage scholars to consider these gaps in the literature when developing future research.  相似文献

This article explores the use made of Christianity during the Second World War and the dilemmas created for the Allies by Stalin's religious record. It is particularly concerned with the way in which Christianity appeared for a while to become a bridge between East and West, with the explicit promise of continued post-war co-operation. However, in the immediate aftermath of the war, Anglo-American policies in particular switched from using Christianity to rehabilitate the adverse image of the Soviet regime to what had been the inter-war policy of using religion to demonise it. Inter-war demonisation held up the Soviet Union as a model not to be emulated. Post-war demonisation pointed to the Soviet Union as an expansionist threat bent on world domination. The article examines Stalin's responses, and Allied perceptions of those responses, to the changes in Western religious policy and propaganda from the Second World War to the emergence of the cold war. The article seeks to show how both sides used religion for political purposes, but that in the final analysis Western reluctance to relinquish what was perhaps its most emotive means of indicting and containing Communism meant that Christianity, instead of becoming a bridge, became a divisive factor that contributed to both the onset of the cold war and public acceptance of it.  相似文献

ABSTRACT

Shellfish remains excavated from an early agricultural village on the Pacific Coast of Mexico (Guerrero) indicate a dietary shift from locally obtained estuarine shellfish (1400–1100 BC) to a greater diversity of mollusks collected from more distant marine environments (900–500 BC). The timing of this shift suggests that it occurred as human populations increased and impacted the availability of local estuarine resources. We argue that this prompted the incorporation of a more diverse array of shellfish species harvested at greater distances or obtained via trade, possibly with the use of boats to transport shellfish and other resources back to the village.  相似文献

Renewable energy policy has far‐reaching implications for national and international economic, environmental, and political sustainability, but thus far within the United States it has been almost entirely the province of state governments. This article examines the factors motivating state‐level policymakers to adopt different forms of a renewable portfolio standard (RPS), highlighting the distinction between degrees of policy stringency, ranging from entirely voluntary participation to rigorous and strictly enforced targets. In the process we introduce a new metric for assessing stringency, more precise and reliable than the various proxies used previously, and analyze its relationship to drivers of policy adoption. We find that policies of different stringencies are motivated by systematically different underlying factors. State‐level citizen political ideology is a significant predictor of RPS policy adoption, particularly for “voluntary” and “weak” policy designs. “Strong” policy designs, on the other hand, are best predicted by ideology at the government level, i.e., the degree of institutional liberalism. These findings may inform current implementation and program evaluation efforts, and potentially point the way toward more effective policy choices if and when an RPS moves forward on the national policy agenda, while the stringency metric central to this analysis can be of use to other policy scholars concerned with topics both within and beyond the realm of energy policy.  相似文献

This article is about the Anglo-Franco-Soviet negotiations in 1939 for an alliance against Nazi Germany and about how the British government later tried to represent those negotiations to public opinion. The first part of the essay presents the Soviet point of view on the negotiations and how the British and French governments, though mainly the British, reacted to Soviet alliance proposals. It is a fresh representation of the Soviet perspective from published and unpublished Russian language sources.

The second part of the essay focuses on how the British sought to represent the abortive negotiations through a white paper, placing the blame for failure on the Soviet Union. France opposed publication because, however carefully prepared, the white paper showed that the Soviet side had made serious alliance proposals with precise, reciprocal undertakings which the British government was reticent to entertain. The French were all the more annoyed because the white paper omitted to underline that they had been more receptive to Soviet proposals.

The trilingual, multi-archival evidence presented in the first part of the essay effectively supports the French perception of the white paper and more generally of the failed tripartite negotiations.  相似文献
