Achieving an accurate perception of time and context remains a major challenge in archaeology. This paper highlights the potential benefits of microstratigraphic study to address this goal, drawing on case studies from Lower, Middle, and Upper Paleolithic, Neolithic, and Iron Age archaeological sites. First, we discuss the importance of site formation reconstruction and the ways in which current field methods approach the sedimentary record. Then, we focus on both field identification and high-resolution study of stratigraphic contacts, which are ubiquitous in archaeological deposits. Examples are presented to highlight the role of microstratigraphy in characterizing the nature of contacts and their significance for archaeological interpretation. A microstratigraphic approach is especially useful for distinguishing between contacts that originate from changes in depositional processes and contacts that form as a result of post-depositional processes such as pedogenesis, diagenesis, or burning. Further examples show how “invisible” anthropogenic surfaces and different kinds of occupation deposits can come to light at a microscopic scale of observation. Finally, we illustrate cases in which what appeared to be sterile layers in the field yielded anthropogenic elements. In the end, we discuss how archaeological projects might incorporate microstratigraphic analyses and their results within broader research frameworks that prioritize site formation process reconstruction.  相似文献

The prevalence, distribution, and location of dental caries were studied in complete and partial human dentitions dating from the Viking Age dating (900–1050 AD) excavated in Kopparsvik on island of Gotland, Sweden. 18 individuals and a total of 370 teeth were examined, using a strong light source and dental probe. Carious lesions were found in a large number of the individuals, 14 out of 18. The percentage of teeth affected by caries (11,9%) corresponds well with studied skull materials from the same period. The surface most susceptible to caries was the occlusal surface, whereas only a few proximal lesions and one single carious root surface was found. The tooth most commonly affected by caries was the mandibular first molar. The tooth most commonly missing ante‐mortem was also the mandibular molar, and the tooth most commonly missing post mortem was the mandibular incisor. Other findings included apical infections, which were detected clinically in 3% of the teeth.  相似文献

ABSTRACT

This paper will examine settlement location during the Iron Age in the northeast part of the Netherlands, an area shaped by Pleistocene geology. In recent years, a number of Late Iron Age/Early Roman settlements situated on the low lying slopes of sand ridges and nearby stream ridges revealed traces of an earlier Iron Age occupation. Palynological data revealed that this part of the landscape was used by humans before it was transformed into an area of settlement. An analysis of excavation data from two key sites at Denekamp-De Borchert and Groningen-Helpermaar, as well as other known sites, lead to the conclusion that the transformation of ‘peripheral landscapes’ into permanent settlement locations was preceded by a phase of arable cultivation which left no trace of permanent habitation. It is also suggested that the impact of human behaviour on the natural landscape in the Early and Middle Iron Age was much bigger than previously anticipated. When excavating this type of settlement areas dating to the Late Iron Age, archaeologists must be aware that only of a small group of archaeological features exist. The proposed model for the choice of settlement location may be more widespread, because of similarities in landscape between the study area presented here and other landscapes in Northwest-Europe (e.g. parts of Germany and Denmark).  相似文献

The essay shows that the axiomatics of the systemic‐cybernetic‐biological theory of self‐organization by Humberto Maturana and Francisco Varela have their roots in the philosophy of German Idealism. Especially the completely subject‐centered philosophy of Johann Gottlieb Fichte already contains the central axiomatics of Maturana and Varela.  相似文献

This article analyses how neoliberal restructuring encouraged the use of participatory methods in agricultural research in Bolivia and how, at a later stage, participatory development initiatives had to be adapted to prevent conflicts with the post‐neoliberal views of farmer organizations. The article contributes to the debate on the normalization of participatory methods in agrarian development. Engaging with Foucault's work on governmentality and neoliberalism, our analysis goes beyond interpretations of participation which conceptualize it exclusively as a technology of power to discipline subjects. Drawing on a distinction between a liberal and a neoliberal moment in the restructuring of agricultural research, we study the case of PROINPA (Foundation for the Promotion and Research of Andean Products), a national NGO that was once part of the state system for agricultural research but was then privatized. Although PROINPA employed participation mainly to enhance managerial effectiveness, it also facilitated moments of participation from below. We argue that participation designed by this type of NGO is not just ‘technical’ as PROINPA professionals would like to perceive it, nor is it simply ‘political’ as critical views on participation hold. Instead it is malleable in the sense that each actor is involved in finding a new balance between technical, economic and political considerations.  相似文献

Under Bishop Rodrigo Cascante (1147–90), the northern Iberian diocese of Calahorra made its first significant administrative inroads into Alava and Vizcaya since its nominal assimilation of those Basque provinces around 1090. An examination into the fluctuating history of Calahorra's administrative penetration of its Basque provinces during this period highlights the extreme difficulty of this undertaking, which was severely hampered by the opposition of a strong Basque regional nobility. It also reveals a close connection between the fluctuations that characterized Calahorra's administrative fortunes north of the Ebro and the see's turbulent political context, defined by its position straddling a volatile frontier between Castile, Navarre and Aragon. Finally, it provides a useful opportunity to analyse Rodrigo Cascante's changing relationships with the secular powers that competed for the territory of his Riojan see. This analysis leads to the conclusion that the bishop of Calahorra was not a passive partner in these relationships, but actively adjusted his stance with respect to the crowns of Castile and Aragon, primarily in function of how well they did, or might, contribute to the realization of his Basque agenda.  相似文献
