The problem of how to describe and account for the present can be identified as a particular preoccupation of poets of the so-called Northern Irish renaissance. This article examines how the temporal deictic ‘now’ functions in some well-known poems by Seamus Heaney, Michael Longley and Derek Mahon. All three poets explore how to combine the plausibility of lyric derived from an individual consciousness with the authority of narrative derived from social interactions. This article will do three related things. First, it will argue that discussing ‘now’ as a temporal deictic enables us to appreciate the full ambiguity and complexity of some poems written at the height of the Northern Irish Troubles. Second, the article will argue that these poems reveal that ‘now’ actually functions in poetry more complexly than some theorists of deixis have allowed. Finally, the article will suggest newly fruitful ways of combining literary stylistics with more conventional close reading.  相似文献

An archaeological GIS is used to examine the late eighteenth-century cultural landscape of St. John, US Virgin Islands. Land use patterns are reconstructed using a combination of historic maps, tax records, and survey reconnaissance. The study demonstrates significant, heretofore undocumented, transitions taking place that reflect dynamic cultural and economic change within Danish West Indian plantation society that includes a significant trend towards land ownership by free-colored St. Johnians more than a half a century before emancipation. These venues of freedom are discussed in relation to broader patterns of estate consolidation and economic shifts.  相似文献

Archaeologists generally agree that Paleoindian residential groups moved regularly over extremely large ranges. However, on the Great Plains, this argument depends substantially on datasets derived largely or entirely from projectile points rather than from systematic analysis of a wide range of artifacts. This paper argues that projectile points differ from most Paleoindian tools in ways that make such datasets unlikely to be reliable sources of information on range sizes. Furthermore, evidence from Paleoindian tool caches and the condition of discarded points suggest strongly that the raw material used to produce projectile points at least sometimes moved across the Plains independently of material used to make most other kinds of flaked stone tools. This, in turn, implies that not all stone used during Paleoindian times was procured by visits of whole residential groups to raw material sources, raising serious questions about the validity of widespread views of Paleoindian mobility.  相似文献

Seasonality determination using stable oxygen isotope (δ18O) analyses in archaeological mollusk shell has been largely limited to aquatic settings where one of the two factors that control shell δ18O – water δ18O (or salinity) and temperature – is assumed to be constant. Open coastal marine environments reflect the former situation, and tropical estuaries constitute the latter. In an effort to expand stable isotope seasonality to an ecological setting where neither variable remains constant, we present a model of annual shell δ18O cycle of aragonite deposition derived from instrumental data on salinity and temperature from San Francisco Bay, California. The predicted range of modeled shell δ18O is consistent with observed δ18O values in prehistoric and modern shells when local conditions are considered. Measurements of δ18O taken at 0 mm and 2 mm from the terminal growth margin were made on 36 archaeological specimens of Macoma nasuta from a late Holocene hunter-gatherer site CA-ALA-17, and season of collection was inferred using the shell δ18O model. We conclude that shellfish exploitation occurred through the year with the exception of fall, which may indicate scheduling conflicts with acorn harvesting or other seasonally abundant resources elsewhere. The model supports the feasibility of stable isotope seasonality studies in temperate estuaries, provided that instrumental records are available to quantify the relevant water conditions at appropriate spatial and temporal scales.  相似文献

Biometry is useful for a suite of analyses relevant to zooarchaeology, which include analysis of mortality profiles, taphonomy, paleoecology, among other purposes. Here, size-age prediction models are developed for 10 freshwater mussel species found in north Texas to develop a method for studying paleoenvironmental conditions. Shell length is often used to evaluate the structures of modern mussel populations, but its use on paleozoological specimens is not feasible because complete shells rarely preserve. Instead, pallial line-to-lateral teeth length (PLL) and pseudocardinal teeth-to-pallial line length (PSP) are evaluated as proxy measures for shell length. Linear regression models based on PLL and PSP using modern mussels demonstrate that they are accurate proxies of shell length for multiple species from a variety of habitats. In addition, ontogenetic-age structures for a modern sample and for two late Holocene assemblages from north Texas are developed using PLL and PSP. These techniques are useful tools for evaluating past ecological conditions of freshwater mussel populations when large samples are available for study, which expands analytical potential of zooarchaeological studies of prehistoric unionid remains.  相似文献

Islam came to China via the Silk Road, the great trading route beginning in the ancient Chinese capital of Xian. Islam flourished during the brutal but religiously tolerant Mongol Yuan dynasty. Harsh repressive measures were employed against the rebellious Muslims of the Qing dynasty. Islam has survived the tumultuous 20th century and has experienced a revival in the new millennium. Following a brief historical overview, including some of China's relevant history of insurrection, rebellion and reforms, the nature of the Muslim community in China, along with pressing contemporary issues, will be outlined and discussed.  相似文献
