AbstractThis paper presents ethnographic, historic and archaeological data from the western Mediterranean in order to explore the variability of storage methods and the various strategies that may have existed in the past in this region. The paper includes ethnographic information on traditional storage methods collected in farming communities in northern Morocco (Rif area). We record the use of plant fibres such as canes (Arundo donax), dwarf palm (Chamaerops humilis), esparto grass (Stipa tenacissima) and dis (Ampelodesmos mauritanica) to make containers. Recipients made of cow dung and unfired clay, as well as underground silos, have been also used in this region to store food. In addition, we explore historical and ethnohistorical data on the use of large storage structures, including the study of communal granaries, a particular type of granary located at inaccessible places, such as cliff faces or mountain tops, or within fortified buildings, from which harvests can be easily protected and defended. We also examine the archaeological evidence of storage strategies in the Iberian Peninsula during prehistoric times. The paper informs of the large variety of systems and materials used, the functioning of storage structures, and more generally, provides a framework for reflecting on the enormous diversity of solutions that could have existed in the past and that may have left little or none archeological traces. 相似文献

The recovery of ancient DNA from archaeological wheat samples under different preservation conditions was assessed using a number of genetic markers. It was possible to amplify nuclear DNA from desiccated grains but not from charred. The desiccated grain was from a pre-Hispanic grain silo in Gran Canaria and showed excellent DNA preservation, enabling the amplification of the ribosomal DNA markers IGS and ITS, the upstream region of the HMW-glutenin locus and single-locus nuclear microsatellites. Our results demonstrated the presence of both durum and bread wheat in an assemblage of naked grain. We were also able to identify different genotypes in durum wheat and compare these with extant landraces, providing insights into the agrarian practices of the ancient Canarians and the origin of their crops. 相似文献

Memories are crucial to our construction of place. They simultaneously offer an anchor for identity and different temporalities to encounters with landscapes. Memory allows different spaces, pasts, and futures to become embedded in particular locales. Yet the spontaneous assemblages of meaning that memory enables are not apolitical. Thus the mechanisms and processes by which meaning is articulated in these encounters are fundamental to our understandings of place. This paper, therefore, brings together the work of Henri Bergson on memory and Paul Ricoeur on narrative, to examine the stories individuals produce which define the self. By drawing on research into the lives of young people in the countryside, the paper does three things: it discusses the role of memory in creating identity; it examines the political process of narrative by which memories become woven into understandings of place and create a bricolage of the here; and finally, it offers the ‘storied-self’ as a resolution of the competing constructions and experiences of personal continuity and the inconsistencies and constant change in the project of the individual. 相似文献

Robustness of econometrically estimated local multipliers across different methods and data 下载免费PDF全文

Local traded‐goods employment multiplier estimates play an important role in the decision making of local policy makers. Therefore, it is important to understand the robustness of the approaches and quality of the data used in empirical studies. The local employment multiplier estimates by Moretti (AER; 2010) are a good benchmark for departure. In this paper, I find the traded‐goods multiplier falls within the range of 1.17 to 1.93, which is substantially lower than the estimate of 2.6 obtained by Moretti. I use multiple estimators in combination with two data sets, a range of controls and different ways of classifying traded industries to show the robustness and variability of local employment multiplier estimates. Finally, I demonstrate the sensitivity of Moretti's results. The most notable result being that Moretti's multiplier for separate skilled or unskilled workers in the nontraded sector is overestimated by a factor of 2. 相似文献

Cities raise major challenges and opportunities for achieving sustainability. Much literature on urban sustainability focuses on specific aspects such as planning practices, urban policy or the diffusion of more sustainable technologies or practices. However, attempts at understanding the mechanisms of structural change towards sustainability have resulted in the emergence of an interdisciplinary field of sustainability transitions research. Transitions research has developed a phase model of transitions in which predevelopment, take-off, acceleration and stabilization phases are distinguished. However, the acceleration phase has received limited attention so far. This is a crucial gap as policy-makers are keen to accelerate transitions. This paper aims to enhance our understanding of how local actions contribute towards accelerating urban sustainability transitions. It does so by testing an acceleration mechanisms framework through exploring the collective agency of local initiatives in urban sustainability transitions. Drawing on a case study of the city of Brighton and Hove (UK), the paper finds that despite favourable local political conditions, there is a lack of evidence of acceleration apart from in individual domains such as food or mobility. Progress is found to depend on the agency of initiatives to both scale up sustainable practices and embed these practices into local governance arrangements. 相似文献
