Starch granules are being successfully recovered from an increasing range of artefacts. Here we present the recovery of starches from carbonised ceramic ‘foodcrusts’ from late Mesolithic–early Neolithic residues at the site of Neustadt in northern Germany. A method for investigating background loading of residues with contaminant starches is proposed by comparing interior ‘foodcrusts’ versus exterior ‘sooting’, for the purposes of eliminating samples with insignificant quantities of grains from subsequent identification procedures. The classification of starches to plant taxon is traditionally achieved by manual observations and measurement of nominal and ratio morphological variables. Here, we present a method for the automated classification of granules, using software developed in-house. The results show that when multiple granules are considered, the species selected as modern reference examples can be classified to high levels of specificity. When applied to the archaeological samples we show that wild plant resources persist in importance across the transition to agriculture, with high proportions of granule forms consistent with acorn (Quercus sp.) occurring in all samples. Hazelnut (Corylus avellana) types are less well-represented suggesting it was not an important food in the context of pottery, and may have been over-represented in the repertoire of hunter–gatherer resources. Cereals are not represented in any of the samples, supporting the notion that their adoption may have been a slow process, occurring more gradually than for other domesticated foods, or that they were not initially processed in ceramic vessels. 相似文献

Immediately after the Civil War, the Plains Border in central Kansas offered the westering peasant a set of new challenges. In an almost treeless environment, a suitable building material was a prominent prerequisite for permanent settlement. Its almost universal availability together with its conveniently uniform thickness and initial softness made the Fencepost limestone a suitable substitute for wood. Its dimensions, color and texture impart to the entire cultural landscape an element of uniformity anda unique folk character. Houses and barns, churches and stores, even curbstones and fences display the character of this important building stone. Quarrying and building were accomplished by laymen and their methods, employing uncomplicated tools, resulted in a straightforward vernacular architecture. While several design types appeared, ethnic affinity was expressed in the treatment of appurtenances rather than by any overt distinction of design. The use of stone represents the influence of material availability rather than ethnic experience. Rail service brought lumber into competition with stone and after the 1920s the use of stone was discontinued. The veneration of old things, current in the country, has placed the stone forms remaining on the threshold of a new popularity and appears to assure their survival 相似文献

Plato and Xenophon ‐ contrary to Dover's interpretation of the Clouds ‐ provide the background to Aristophanes’ caricature of Socrates: viewed against that background, Aristophanes’ jokes in the Clouds lose their obscurity, his comedy gains on poignancy and artistic unity; Plato's and Xenophon's Socrates regains historicity. 相似文献

Archaeological work in advance of construction at a site on the edge of York, UK, yielded human remains of prehistoric to Romano-British date. Amongst these was a mandible and cranium, the intra-cranial space of which contained shrunken but macroscopically recognizable remains of a brain. Although the distinctive surface morphology of the organ is preserved, little recognizable brain histology survives. Though rare, the survival of brain tissue in otherwise skeletalised human remains from wet burial environments is not unique. A survey of the literature shows that similar brain masses have been previously reported in diverse circumstances. We argue for a greater awareness of these brain masses and for more attention to be paid to their detection and identification in order to improve the reporting rate and to allow a more comprehensive study of this rare archaeological survival. 相似文献

The 2011 British referendum on the electoral system offered voters a change within the majoritarian family from single-member plurality to the alternative vote. The alternative vote is not proportional, but the ‘yes’ campaign in the United Kingdom included small parties and ‘democracy sector’ organisations previously associated with advocating proportional representation. This anomalous behaviour can be explained by applying social movement theory, especially interpretations related to political opportunity structures and frame analysis. The Liberal Democrats, Electoral Reform Society and others had previously criticised the alternative vote, yet decided to campaign in favour of it. This led to an unclear framing of their objectives and, ultimately, their failure.
2011年英国就选举制进行的公投为这个多数决体系的选民提供了一种从简单多数到排序复选的变革。排序复选并非比例制,但英国的“yes”运动包括先前主张比例代表制的小党和“民主部门”的组织。这样的缺少一贯之道可以用社会运动的理论特别是政治—机会的结构和框架分析来解释。自由民主派、选举改革学会及其他先前批评排序复选制的组织又决定声援它。这造成其目标的模糊和最终的失败。 相似文献
