In luminescence dating, the potassium concentration significantly contributes to the dose rate value in the age estimation. Within this study, fine-grain thermoluminescence dating has been applied on sherds of calcareous pottery of known age, excavated at a Roman site in Mallorca, Spain. For those of the samples that showed signs of severe potassium leaching, according to chemical and mineralogical examination, the thermoluminescence analysis provided overestimated dates. By using the known archaeological age of the samples, a corrected dose rate value can be estimated which provides the potassium concentration averaged for the burial period. Finally, a step-like model can then be used to estimate the fraction of the burial period after which most of the alteration effects took place.  相似文献

This article addresses the problem of specification uncertainty in modeling spatial economic theories in stochastic form. It is ascertained that the traditional approach to spatial econometric modeling does not adequately deal with the type and extent of specification uncertainty commonly encountered in spatial economic analyses. Two alternative spatial econometric modeling procedures proposed in the literature are reviewed and shown to be suitable for analyzing systematically two sources of specification uncertainty, viz., the level of aggregation and the spatio-temporal dynamic structure in multiregional econometric models. The usefulness of one of these specification procedures is illustrated by the construction of a simple multiregional model for The Netherlands.  相似文献

Between March and May 2010 a series of school killings took place in mainland China. This article explores media discourses on the school killings and examines three cases in detail. It connects the search for underlying reasons and responsible authorities in relation to the murders with the wider search for ‘society’ in contemporary China, and concludes by emphasizing the gap between the official promotion of the idea of ‘society’ as a cohesive moral community and a parallel popular understanding of the contemporary Chinese social world as a savage wilderness.  相似文献

Microcephaly, characterized by crania with an abnormally small occipitofrontal circumference (OFC), is only sporadically described in paleopathological literature. Accurate identification of individuals suffering from microcephaly is challenging when performed in an archeological context, especially in mild cases, as appropriate reference data are often not available. This study aimed to describe the craniometric characteristics of the Meerenberg (MeB) skeletal collection and to identify microcephalic individuals while focusing on the diagnostic criteria and the influence of reference data on the prevalence of the condition. The value of virtual endocasts as a diagnostic tool was also assessed. Forty-eight adults (1891–1936) excavated from the cemetery of the MeB psychiatric hospital (Bloemendaal, The Netherlands) were investigated. Microcephalic individuals were identified by using the craniometric characteristics of a contemporary Dutch archeological population as reference. In order to investigate the usefulness of modern clinical head circumference reference data on the diagnostic process, cranial OFCs of the MeB individuals were converted to head OFCs. Virtual endocasts were created from the identified microcephalics and three normocephalics. Three MeB females (all <−3 SD) were identified as microcephalic when compared with a sex-matched contemporary archeological reference sample. The same three MeB females were classified as microcephalic when using sex-matched modern clinical reference data and when applying −3 SD of the pooled sex archeological craniometric reference data as cut-off point. No individuals were classified as microcephalic based on the metric characteristics of the virtual endocasts. Microcephaly can only be accurately identified when using sex-matched contemporary population reference data, or in its absence, modern clinical data after soft tissue correction. Should sex estimation be unreliable, a –3 SD cut-off point generated using pooled sex reference data seems suitable as diagnostic tool. Virtual endocast did not support the identification of microcephaly in this study.  相似文献

ABSTRACT

This article suggests that the study of the War of Resistance against Japanese aggression should pay due attention to the effect of the war on the wartime everyday, that is, on Chinese culture, politics, society, and the economy away from the battlefield. Not only was the impact deep and enduring, but evolving, regionally and socially divergent responses to the war also shaped the war’s military. In modern war, as Karl von Clausewitz pointed out, public morale is a key factor in deciding the outcome of the fighting. The article first sketches the war’s impact on the Chinese economy, suggesting that the main consequences were “demodernization” and the revival of traditional trading patterns. It then discusses the reading lives of a young woman who grew up during the war and a senior Nationalist official to delineate contrasting emotional private responses, with one person finding in literature an inspirational alternative and the other becoming increasingly disillusioned. The article concludes with an examination of three popular history textbooks. They all stressed the importance of an awareness of Chinese civilization but narrated its nature and its prospects in contrasting ways. Such textbooks were used in required Chinese history courses at universities. The article makes no attempt to be comprehensive but instead uses a few examples as illustrations of the potential of researching wartime everydayness.  相似文献
