A new accessible and easy method for studying past fire events using ‘dry sediments’ is presented. The method was developed for analysing samples from 17 locations in the Ambato Valley, NW Argentina, to study fire regimes in the area. Based on earlier researchers’ methods, guidelines to use microcharcoals in ‘dry’ sediments as a palaeoenvironmental proxy are provided. The procedures outlined include sampling/extraction in the field, preparations of the samples, laboratory analysis and quantification of the samples. The new approach was useful to meet the objectives and answer the questions initially proposed in our research about past fire regimes affecting the past Aguada society.  相似文献

Understanding how archaeological sites are abandoned is a vital part of archaeology. This paper explores abandonment as a phenomenon in a worldwide context, particularly in relation to sites with evidence of fire, and with a special focus on the South-Central Andes. I evaluate the patterns from an area of the Argentinian Andes and discuss the disappearance of the Aguada Culture, one of the central cultures in Argentinian prehistory, using evidence from the core area the Ambato Valley. I conclude that environmental factors were not the sole or determining source of stress, but rather part of a social–environmental dimension in which several factors combined to push a society into a vulnerable situation. In terms of the abandonment of the Aguada settlements in the Ambato Valley, the study shows that frequent forest fires might have played a role, but based upon the regularity of such events as seen in the sediment history, it is unlikely that these were the only factor in the process of abandonment of the valley.  相似文献

It has been noted that innovation seems to take place to a higher degree in clusters than elsewhere and we have lately seen a worldwide wave of emerging cluster initiatives and similar innovation policy projects. Some of these are realistic efforts based on existing regional strengths and partly existing cluster structures. Most, however, are grasping at straws. The latter is especially true when it comes to technologies such as IT and biotech. We could subsequently add a new label—“pathetic clusters”—to the already existing list of embryonic, emerging, world-class or stagnating clusters. But what do we make of such “pathetic clusters” (are they really pathetic)? Although economic geographers often tend to explain innovation (competitiveness) by looking at cluster dynamics, in such accounts, the cluster concept itself can actually function as an innovation, imposing similar effects on the economy as more familiar types of innovation would, i.e. by creating a local competitive edge. It is reasonable to believe that if “pathetic clusters” play important roles in regional economies, then they do so in the form of social and organizational innovations rather than as Porterian drivers of innovation and industrial dynamics on a large scale. This function of the cluster concept—as a local innovation—is the focus of the paper at hand.  相似文献

The success of radiocarbon dating of burned or cremated bones depends on the exposed temperature during burning and the degree of re-crystallisation of the inorganic bone matrix. We present a method for characterisation of likely cremated bones by employing visual inspection, infrared spectrometry and carbon stable isotope analysis on the bio-apatite fraction. The method of radiocarbon dating of cremated bones was tested by dating paired samples of bone and associated context materials such as pitch, charcoal and a dendrochronologically dated oak coffin. The dating of these paired test samples were largely performed as blind tests and showed excellent agreement between pitch and bone. The weighted mean age difference of all test samples is observed to −9 ± 60 14C yr. To test the indicators and the effects of the degree of burning, a Late-Neolithic human individual has been studied, as this individual exhibits the full spectrum from low temperature burning (charred) to high temperature (“cremated”) from one end of a single bone to the other. This is reflected as a marked step in numerous parameters as well as in a significant difference in 14C age between the charred and the cremated bone samples.  相似文献

Abstract

Rural areas are facing prospects of marginalization and peripherality in an age of globalization where the attention of governments and media focuses increasingly on the (lack of) competitiveness of urban and metropolitan regions in Europe. Many rural areas have, therefore, searched for ways to improve their position vis-à-vis other localities by mobilizing local resources and employing policy tools that are believed to foster indigenous social and economic development, including place branding. Unsurprisingly, using food as a means to profile rural localities has become widespread, with branding efforts revolving around local food festivals that commodify local cultural resources. The article attempts to illuminate the challenges faced by branding processes in rural areas through a case study of Løgstør, a small rural town in North Jutland, Denmark, which builds its branding efforts around an annual mussel festival. The analysis focuses on the relationship between stakeholders and branding strategies, and in particular aims to uncover the role of the food festival in aggravating or alleviating inherent tensions between different stakeholders and target groups. It is argued that in the case of Løgstør making a food festival pivotal, a signature event for the place branding efforts has been created, which appeals to both external and internal audiences, and that this may hold wider lessons for place-branding initiatives in other small towns across Europe.  相似文献
