Livestock was often released onto remote Southern Ocean islands as a food source for shipwreck survivors during the industrial whaling and sealing era. Although animals were put ashore at nearby Isles Kerguelen and Crozet, the historical records make no mention of domesticated livestock ever being set ashore at Heard Island between 1855 and 1882. Here we report a pig (Sus scrofa) mandible discovered amongst other bones and artefacts in an ??elephanters?? midden found at Spit Bay, Heard Island. The find provides very strong evidence a live pig was shipped ashore and eaten as part of the sealers meagre provisions. Archaeological investigations of middens at other sealing locations could produce new insights into the dietary habits of these men. 相似文献

ABSTRACT A belief that EU integration is incomplete is often predicated on a comparison to U.S. states. Yet, with low barriers to trade and factor mobility between EU countries, is this belief correct? To address this question, we develop three theoretical predictions regarding the distribution of output and factors across members of an integrated economic area with harmonized policies and free movement of goods and factors. Empirical tests strongly support these predictions for U.S. states and 14 EU countries. Constructing a measure of integration, we find that EU integration rose from the 1960s to equal that of U.S. states by 2000. 相似文献

Previous aDNA research in the Southwest provides a framework to understand the Mimbres population which maintains a unique identity in the archeology of the desert Southwest of North America. Both the mitochondrial DNA (mtDNA) haplogroups and haplotypes of a sample of 46 Mimbres individuals were identified from skeletal remains and compared to those of other ancient and modern populations in the American Southwest and Mexico. The haplogroup frequency distribution of the Mimbres resembles that of other Southwestern populations, suggesting a close relationship between the Mimbres and the neighboring populations and population continuity for a long period of time. However, their relatively low frequency of haplogroup A (11% n = 5) is consistent with a clinal distribution of haplogroup A from Mesoamerica to the Southwest. Moreover, unlike other Southwestern populations, the Mimbres share haplotypes with populations to the south, such as the Cora, Huichol, and Nahua, suggesting gene-flow from Mesoamerica. Here we discuss this data in light of the origin of the Mimbres population and their relationship to other Southwestern and Mexican populations. 相似文献

Abstract Two great movie directors were both born in 1930. One of them, Jean-Luc Godard, revolutionized filmmaking during his 30s and declined in creativity thereafter. In contrast, Clint Eastwood did not direct his first movie until he had passed the age of 40 and did not emerge as an important director until after he was 60. This dramatic difference in life cycles was not accidental, but was a characteristic example of a pattern that has been identified across the arts: Godard was a conceptual innovator who peaked early, whereas Eastwood was an experimental innovator who improved with experience. This article examines the goals, methods, and creative life cycles of Godard, Eastwood, and eight other directors who were the most important filmmakers of the second half of the twentieth century. Francis Ford Coppola, Stanley Kubrick, Stephen Spielberg, and François Truffaut join Godard in the category of conceptual young geniuses, while Woody Allen, Robert Altman, John Cassavetes, and Martin Scorsese are classed with Eastwood as experimental old masters. In an era in which conceptual innovators have dominated a number of artistic activities, the strong representation of experimental innovators among the greatest film directors is an interesting phenomenon. 相似文献

ABSTRACT Spatial models whose weighting matrices have blocks of equal elements might be considered if units are viewed as equally distant within certain neighborhoods, but unrelated between neighborhoods. We give exact small sample results for such models that contain a spatially lagged‐dependent variable. We consider cases in which the data relate to one or more panels, for example, villages, schools, etc. Our results are consistent with large sample results given in Kelejian and Prucha (2002) but indicate a variety of issues they did not consider. 相似文献

Understanding the nature of the physical properties of lithic raw materials is a pre-requisite for developing more reliable interpretations of use-wear evidence and tool function. We use nanoindentation and use-wear experimentation as a way to measure differences in raw material surface hardness and roughness in order to show that differences in lithic material properties have implications for rates of use-wear accrual. 相似文献
