The chemical compositions of 14 glass beads from two Early Sarmatian-period burials were determined. Al, Ca, Fe, Mg, K, Na, and Si were measured by electron probe microbeam analysis, while the Co, Cu, Ga, Mn, Ni, Pb, Rb, Sr, Th, Ti, Y, Zn, and Zr contents were measured using energy dispersive X-ray fluorescence. All the beads can be classed as low-magnesia soda-lime-silica glasses. The blue glass beads examined in this study were coloured with Co and Cu containing minerals. Cluster analysis and principal components analysis suggest that two distinct glass recipes were used to manufacture these beads. 相似文献

In an effort to make measurements readily available as soon as possible, dates from the Oxford Radiocarbon Accelerator will now be published regularly in Archaeometry. These datelists will not be a substitute for final publication in Radiocarbon, which is desirable for all dates, but are intended to serve as a formal interim publication of dates, so that they can be cited. 相似文献

Place branding in heritage tourism development is presented as a strategy that opens up new possibilities for attracting investors and visitors by distilling, capturing and shaping what is distinctive about a place. This representational fix is an efficient marketing device in the sense that it represents places through widely intelligible symbols. Branding is also a limiting activity that locks places in time and class relations. While place branding has always had this dual effect, we argue that it has particularly insidious and limiting consequences for local development under current conditions of roll‐out neoliberalism. Beginning in the 1960s, several prominent residents and outsiders initiated efforts to transform the Town of Cobalt, Ontario, into a mining heritage tourism destination. In 2001, the town entered and won a contest to be named Ontario's Most Historic Town. The following year it persuaded Parks Canada to designate it as a national historic site. These two events provided renewed external validation for the efforts to brand Cobalt as a heritage site and began a new cycle of mining heritage tourism development. However, instead of breaking the dependency relationships that characterize resource regions, the current round of place branding has acted to circumscribe the range of possible economic development options. 相似文献

It has been 10 years since the Indian Ocean Tsunami caused serious damage to the coastal areas in South and Southeast Asia. The effects on vegetation and human settlements in the affected areas were enormous. This study presents the results of an analysis estimating the long‐term recovery using two longitudinal remotely sensed dataset: 1. Moderate Resolution Imaging Spectroradiometer enhanced vegetation index (MODIS EVI), a dataset accounting for change in the landscape and vegetation; and 2. Defense Meteorological Satellite Program‐Optical Line Scanner (DMSP‐OLS) night‐time light data in order to estimate the effects on human and economic activities. It is evident from the results of this study that the night‐time light and vegetation index datasets can both be beneficial in identifying changes caused by natural disasters and can be used to track recovery. The results using night‐time light indicates a large loss of lighted area but also a rapid recovery of night‐time light after the tsunami. Already in year 2005–2006, the levels of lighted area and sum of the lighting (SOL) intensity reached the same levels as pre‐tsunami. For MODIS vegetation index, a drop can be observed in 2005/2006 on locations close to the coastline using 1 year temporal resolution; however, when utilizing the 16 day temporal resolution, the impact of the tsunami is illustrated as a dramatic drop, mostly in pixels located within 3km from the coast. Following the drop in vegetation index due to the tsunami, it was observed that most pixels exhibited at least some level of recovery in 2 years after the event. 相似文献
