As I write this, Little Rock is gearing up for the fiftiethanniversary of the desegregation of Central High School, thatnigh archetypal event which seemed to pitch the forces of progressagainst those of ignorance and Southern intransigence. Preciselybecause it is often viewed in such starkly Manichaean terms,the Central High crisis has become the focal point in yet anotherbattle for memory, with some former students—white students—disparagingthe attention paid to the Little Rock Nine, insisting that they,too, suffered during that tumultuous school year. Further, theonly statewide newspaper in Arkansas is headed up by a formerplayer in the crisis who routinely recasts Governor Orval Faubusas a  相似文献

Since 1999, there has been much debate within the international community on what the future status of the autonomous province of Kosovo should be. However, there seems to have been little consideration as to why the Ottoman vilayet of Kosovo and the other majority Albanian-speaking areas (now parts of Montenegro, western Macedonia and north-western Greece) did not become either independent or part of an independent Albanian state, despite the legacy of these decisions. Focussing on British policy and perceptions, this article explores the role of the great powers in the delimitation of Albanian boundaries, particularly in two boundary commissions in 1913 and 1914: one determining the southern Albanian boundary with Greece and the other concerning the northern and north-eastern boundary with Serbia and Montenegro. The first part of the article considers the influences and interactions of two sets of factors in the boundary deliberations: the declared rationale of creating nation-states in south-eastern Europe based upon ethnographic criteria (linguistic boundaries) and the competing role of geopolitical interests in their decision-making, focussing particularly upon British interests. It illustrates that the decisions made to delimit the newly independent Albanian state primarily reflected the resulting great power conflicts and compensations, rather than the professed ethnographic rationale. The second part of the article explores some of the consequences of the decisions made to delimit Albanian boundaries, especially in ‘ethnic’ or national terms.  相似文献

We studied the faunal remains from the Early and Middle PPNB site of Motza, Judean Mts., Israel, in order to gain insight into the economic basis prior to livestock husbandry, with a focus on gazelle hunting. Taphonomic analysis showed that bone preservation at the site was excellent. The subsistence economy in Motza was based on a broad spectrum of hunted species, with mountain gazelle (Gazella gazella) as the dominant prey, similar to many Epipalaeolithic and Pre-Pottery Neolithic sites in the southern Levant. We studied gazelle exploitation patterns, in order to learn about the interaction of humans with this species prior to ungulate domestication. Analysis of the demography of the gazelle herd, which included aging and sexing, revealed no age preferences and no selective culling. Moreover, the PPNB gazelle population of Motza does not exhibit allometric changes in morphology, that are allegedly correlated to increased hunting pressure on gazelle populations prior to livestock domestication.  相似文献

The comparison of survivorship curves derived from seven different models aiming to reconstruct ancient sheep and goat herd maintenance strategies (e.g. optimization of wool, meat, and milk production) shows that many of these models cannot be distinguished statistically. This observation renders the current theoretical framework for reconstructing ancient herd maintenance strategies problematic, due to the possible indeterminacy of model data analysis. In order to assign empirically observed age-at-death data to a model of herd maintenance strategy, it is suggested that a direct fit of observed data to survivorship curves be forgone in favor of a binning procedure highlighting the differences between fewer and more distinguishable models. The incorporation of high-resolution sexing and taxonomic determination to coarse-grained age-at-death models may go a long way towards solving the current problem of indeterminacy.  相似文献

HOUNDTOR, HUTHOLES AND DINNA CLERKS are three deserted medieval settlements on the granite uplands towards the eastern side of Dartmoor Forest, Devon. Houndtor and Hutholes were small villages comprising eleven and six buildings respectively; Dinna Clerks was an isolated homestead. Extensive excavation at these sites by the late Mrs E. Marie Minter revealed a long sequence o f superimposed houses, divisible into two periods. Those of the first were built of turf. Although their remains were few, and in some places confusing, they provided much information on the construction of this type of building in the South- West of England. During the second period commencing in the middle of the 11th century, the houses of turf were gradually replaced by those of stone. The excavation of the well-preserved remains of the long-houses and their associated barns and corn-driers and the recording of the gardens and some of the open fields have given a clear insight into the ecology of a community dependent upon mixed farming at altitudes between 1100 and 1300 ft above sea level. The excavation of these settlements has also demonstrated how the deterioration of the climate in the late 14th and early 14th centuries led to their eventual desertion.  相似文献

In his novel The Adventures of Telemachus, François de la Mothe-Fénelon (1651–1715) presents a utopian society, Boetica, in which the role of luxury, war and trade is extremely limited. In unreformed Salentum, on the other hand, Fénelon shows the opposite image, one in which the three elements reinforce each other in a fatal feedback-loop. I analyse the relationship between luxury, war and trade in the Telemachus and I sketch the background to Fénelon's views, with special attention to the military expansion and the mercantilism of Louis XIV, Fénelon's quietist spirituality, and the development of the concept of self-interest in seventeenth-century philosophy by mechanicist philosophers and economic thinkers.  相似文献
