A reference sample of dental and oral nonmetric traits should represent its biological population from which it stems. The presence of individuals born at different times, different regions, and separate countries in the Coimbra-identified cranial collections provides the test of whether this sample reflects the biological continuity of this Portuguese sample among the late modern (early industrialization, nineteenth century) to early contemporary (early demographic transition, first half of the twentieth century) population of this region of central Portugal. The Coimbra collections were scored for 61 traits using methodology by Hauser and De Stefano (1989), Turner et al. (1991), Scott and Turner (1997), Irish (1998), and Marado and Silva (2016). The 600 individuals in the sample were divided by generation, region, and nationality. Their phenetic diversity was tested with principal component analysis and with the mean measure of divergence statistic. The proximity between the subsamples was generalized, and it mimicked previous genetic marker results. Some small subsamples hindered conclusions; nevertheless, this Coimbra sample is considered a reliable dental reference sample for the Portuguese late modern/early contemporary population.  相似文献

As the criterion used by archaeologists for determining early white porcelain is quite ambiguous, the origin of Chinese white porcelain remains a point of disagreement. In this study, we systematically investigate 61 typical Xing porcelains of the late Northern dynasties to the early Sui dynasty (550–600 CE) using spectrophotometer, X-ray fluorescence (XRF), scanning electron microscopy (SEM), and X-ray powder diffraction (XRD), and analyze the differences between early white porcelain and celadon of Xing kiln in terms of their whiteness and raw materials characteristic. The results show that early white porcelain is a new type of ware that differs from celadon, which can be distinguished by whiteness, with a whiteness greater than 8% being early white porcelain and a whiteness less than 8% being celadon. It is assumed that the ancient potters created the whiter wares based on celadon by improving the glaze and selecting new raw materials for the body, but the production of this type of ware was short lived and subsequently refined in the Sui dynasty (581–618 CE) owing to the limited improvement in whiteness.  相似文献

After the Second World War, there were estimated to be around 20 million half-orphans in Europe. In Germany alone, 5.3 million soldiers killed in action left behind approximately 1.2 million widows, nearly 2.5 million half-orphans and about 100,000 complete orphans. This article examines how men and women from various social strata in western and eastern Germany remember their fathers who died in the war and in what way he has been stored in the family's collective memory. The analysis focuses on 30 life-history interviews with men and women from eastern and western Germany with various social and religious backgrounds, all of whom were born between 1935 and 1945 and had little or no memory of their fathers. The following questions are relevant: what memories did children have of their fathers, and what images of them were related by mothers and relatives? What individual, political, social and memory-cultural factors characterise a child's memory of her or his father? The article also analyses trans-generational transmissions and conflicts of how the father's past is remembered.  相似文献

Lu, J.-F., November 2015. Morphological analysis of Ozarkodina prolata Mawson and Ozarkodina midundenta (Wang & Ziegler) (Emsian conodonts) from South China. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

Investigations of conodonts from Emsian (Lower Devonian) strata at Bahe, Liujing and Daliantang in Guangxi and Yunnan, South China, provide new data on the morphological variability and phylogenetic affinity of Ozarkodina midundenta, a species initially assigned to Pandorinellina but transferred to Ozarkodina herein. Morphological analysis suggests that O. midundenta probably developed from O. prolata by progressive fusion of denticles in the middle third of the blade above the basal cavity in the Pa element.

通过考察多元场对钧瓷文化创意产业知识创造、流动及学习创新的影响发现:①场为主体的地理、社会及文化认知等临近等提供了条件,有助于经验意会及符号知识的获得、共享与传播,有利于思想的交流碰撞及创意萌生;②生产现场、地方关系场、地方社会场与临时性场在钧瓷的学习创新中发挥着不同而又相互补充的作用。生产场推动着集群知识积累和增进,地方关系场促进了行业知识、生产经验及家族核心知识的传播传承,地方社会场形成了地方共享知识信息,而临时场建立起外部通道联系,发挥着更新地方知识库的作用;③地方性的历史文化资源与传统以及地理-社会-文化等临近造就了外围地区文化创意经济的动力,但若未来本地知识更新的机制不够强大,则易产生发展锁定,这是需要未来引起关注的问题。  相似文献

本文旨在考察日本的国际战略在联接中日战争和太平洋战争中所起到的关键作用。分析的重点包括这个国际战略所包含的五个方面:对中国问题的解决方针;对第三国的政策;对九国公约与既有世界秩序的态度;对国际形势的判断;对"中国问题"与"世界问题"相互关系的应对。文章提示:日本最初在国际战略上采取了不刺激第三国的方针,以期将战争限定在中日两国的范围内单独解决。但是,它的实际行为同它的主观意图背道而驰,不自觉地步步推动美国和国际力量走向援华抑日。在深陷困境之后,面对欧洲局势的变化,在对"东亚新秩序"的执着情结和对包括东南亚在内的"大东亚新秩序"的期待心理的推动下,日本决策层在国际战略上与中国殊途同归,确定了"国际性解决"中日战争的方向。随之,其不仅拒绝退出中国,且进一步结盟德意,刻意通过南进收一举多得之效,从而把战争从中国扩大到东南亚和太平洋。在这一过程中,日本的文职官员在很多场合冲到了军人的前面,反映出日本决策背后的深刻背景。  相似文献
