The term avian osteopetrosis is used to describe alterations to the skeletal elements of several species of domestic bird, most typically the chicken, Gallus gallus domesticus (L. 1758). Such lesions are routinely identified in animal bones from archaeological sites due to their distinctive appearance, which is characterised by proliferative diaphyseal thickening. These lesions are relatively uncomplicated for specialists to differentially diagnose and are caused by a range of avian leucosis viruses in a series of subgroups. Only some avian leucosis viruses cause the development of such characteristic lesions in osteological tissue. Viraemia is necessary for the formation of skeletal pathology, and avian osteopetrosis lesions affect skeletal elements at different rates. Lesion expression differs by the age and sex of the infected individual, and environmental conditions have an impact on the prevalence of avian leucosis viruses in poultry flocks. These factors have implications for the ways in which diagnosed instances of avian osteopetrosis in archaeological assemblages are interpreted. By integrating veterinary research with archaeological evidence for the presence of avian leucosis viruses across Western Europe, this paper discusses the nature of these pathogens, outlines criteria for differential diagnosis, and offers a fresh perspective on the human‐aided movement of animal disease in the past through investigation of the incidence and geographic distribution of avian osteopetrosis lesions from the first century BC to the post‐medieval period. © 2017 The Authors International Journal of Osteoarchaeology Published by John Wiley & Sons Ltd. 相似文献

The Arch of Augustus in Susa (north‐western Italy) was built in 9–8 bc by King Cottius, to celebrate the treaty between the Romans and the Gauls. It is made of white marble, which was considered for a long time to be locally extracted, but no archaeometric studies have been performed up to now. Therefore, a multi‐analytical study based on petrographic (optical and scanning electron microscopy), electron microprobe and stable isotope analyses was carried out on the marble from the arch and from reference samples, with the aim of defining the provenance. All the data confirmed that white marble belonging to the metamorphosed carbonate cover of the Dora Maira Massif, known as Foresto marble, was used for the Susa Arch. This choice was probably made for economic reasons, but also due to the relative independence of the ruling family of the Alpes Cottiae, which was obviously interested in promoting a local marble. 相似文献

10世纪前的中国西北边疆经历了开拓、稳定和演变等过程,构成了一个相对完整的发展阶段,边疆发展的各种形态与主要特点尽皆呈现。南农北牧既是西北边疆的基本经济形态,也是历史上中原农业王朝与北方游牧民族角逐态势延伸的主要依据;在作为边疆主体的中原或内地王朝、客体的西域地区和旁体的北方游牧民族等三个主要因素的共同作用下,西北边疆的政治地理范围时有伸缩,而多种统治体制并存、边疆问题与民族问题一体化等特点也贯穿于这一时期西北边疆发展的整个过程。 相似文献

西方传教士来华后,科举制度就成了他们关注的焦点。传教士对科举制度的审视,进一步暴露了科举制度的内在弊端,增强了科举改革的紧迫性;传教士对科举改革的设想,丰富了科举改革的思想,指明了科举改革的方向;传教士的宣传活动,促进了国人思想观念的解放,推动了科举改革的进程。然而,传教士毕竟不是科举改革的主角,其作用与影响终究是有限的。 相似文献

Yan Sun 《International Journal of Historical Archaeology》2006,10(2):159-177
The establishment of the Yan state by the Zhou court during late eleventh century BCE had fulfilled the attempt by the dynastic
power to colonize and control the local population of northern Hebei. The Yan and the two local groups, one active in the
Yan mountainous region and the other in the Jing, Jin, and Tang area, developed a cooperative relationship during the early
Western Zhou period. The cooperation between Yan and local elites was mutually beneficial. While local elite culture was heavily
influenced by that of the Shang and Zhou, local traditions continued to be present. 相似文献

章太炎、刘师培等人在清末“保存国粹”、“复兴古学”的过程中,开始对中国古代学术进行初步整理,肇始了对中国学术遗产进行发掘、梳理、研究和整合之工作。以西方新知、新理、新法整理中国传统旧籍,发明中国旧学之新义,是晚清学术演进之必然趋势。以新知阐释旧学,以中学比附西学,以近代学科体系界定中国旧学,是晚清学者整理中国旧学之基本思路。正是在对中国传统学术不断进行整理和整合的过程中,中国传统学术开始转变其固有形态,逐步融入近代西学新知体系之中。 相似文献

马士是西方公认的汉学先驱之一。在中国海关任职长达30余年的时间里,撰写了一系列有关中国问题的著作,它们对20世纪前半期西方的中国历史学著作产生了深刻的影响。他的许多有关中国近代对外关系的著作,不仅开启了国外中国近代史研究的先声,为国外中国近代史研究奠定了坚实的基础,而且拓宽了西方汉学的研究领域,对西方现代汉学的发展起了重要的推逐作用。 相似文献
