Despite the existence of long-lived tree species with excellent tree-ring characteristics, the use of dendrochronological techniques for dating archaeological contexts has been very limited in South America. Recent research in the Bolivian Altiplano of the Central Andes has yielded a network of Polylepis tarapacana chronologies that goes back to the 13th century. This species was regularly used by local populations since pre-Columbian times as raw material for beams, lintels, hooks and other architectural features in houses, storage chambers, and sepulchers. The aim of this study is to argue in favor of the potential of P. tarapacana for providing high resolution dates of significant archaeological events during the pre-Columbian era. The chronology of chullpas (burial towers and storage chambers) in the southern Andean Altiplano is used as a case study. Growth rings from P. tarapacana have provided several centennial-length dendrochronological records including a reference regional chronology covering the last 786 years in the Central Andean highlands. Based on this long reference chronology calendar years were assigned to woody pieces from pre-Hispanic chullpas. Dendroarchaeological results are consistent with contextual evidence and most radiocarbon dates from woody samples and related archaeological items. Our results indicate that P. tarapacana has a high potential for providing annually-resolved tree-ring dates for archaeological contexts in the Altiplano since the early 13th century. 相似文献

>This paper compares and contrasts the policy initiatives and the likely policy fortunes of two older, and heavily polluted, industrial regions — Upper Silesia in Poland and the Leipzig‐Halle district of the former East Germany. The involvement of local communities in the self‐regulation of structural planning is advocated in favour of state‐regulated planning, a version of which degraded these areas. 相似文献

Between the first and the sixth century a single theological and several medical authors reported on the consumption of gladiator's blood or liver to cure epileptics. The origins of the sacred or apoplectic properties of blood of a slain gladiator, likely lie in Etruscan funeral rites. Although the influence of this religious background faded during the Roman Republic, the magical use of gladiators' blood continued for centuries. After the prohibition of gladiatorial combat in about 400 AD, an executed individual (particularly had he been beheaded) became the "legitimate" successor to the gladiator. Occasional indications in early modern textbooks on medicine as well as reports in the popular literature of the 19th and early 20th century document the existence of this ancient magical practice until modern times. Spontaneous recovery of some forms of epilepsy may be responsible for the illusion of therapeutic effectiveness and for the confirming statements by physicians who have commented on this cure. 相似文献

Knowledge has long been a motor for societal development. However, the way knowledge is produced, distributed and applied has changed considerably and is regionally differentiated. In this paper, it is argued that different types of spatial profiles are discernable at the broader, national level: (i) Prominent hubs emerge, influenced by the knowledge society. (ii) The knowledge society expands to rural areas, being located between metropolitan regions, forming corridors of development. (iii) Regions with a knowledge society deficit, which might be perceived as a sort of “novel periphery”, remain. Drawing on examples from Germany, this paper examines rural regions which can be seen to fit with these profiles, revealing how planning paradigms change in the knowledge society and how spatially sensitive stakeholders can and do use knowledge as a strategic resource. 相似文献
