The central role of grinding activities in the dietary practices of traditional agricultural populations can be approached from an ethnoarchaeological point of view. The comparison of ethnographic references raises the question whether the function and the socioeconomic context in which grinding slabs are used allow to assess issues related to conclusions drawn from archaeological contexts. Our discussion is based on the analysis of the manufacturing of grinding slabs, their use cycles and their social status in several Minyanka villages (Mali), providing useful references when examining the way in which archaeologists explain and interpret technological, functional and spatial observations. The typological and technical evolution and variability of querns results from a combination of several factors determined by the available raw materials, the skill of shaping techniques, the organisation of manufacturing and the transference of the function of grinding tools. But these factors alone cannot explain the encountered range of variation. Our study thus emphasises the very role of cultural aspects within these temporal and regional developments, and the impossibility of dissociating the use of a quern from its socio-economic context. 相似文献

Vibrational spectroscopy (Raman and FTIR) has played an important role in identifying pigments, substrata and deterioration products in rock art studies worldwide: in the laboratory and on-site. However, the detection of organic binders and carrying agents has so far been scarce and the quality of many spectra recorded on-site inadequate. In this study, possible pigments (charcoal, ochre, raptor faeces, thermally treated ostrich egg shell, etc.), binders (fat, egg, blood) and carrying agents (saliva, gall, egg, water) were selected based on artistic considerations and analysed with FTIR and Raman (514.6 and 785 nm excitation, both available in mobile instruments) spectroscopy in order to determine usable marker bands for each ingredient. The resultant marker bands were then used to analyse five ten year old San replica paints. It was found that FTIR spectroscopy is very efficient to identify organic compounds as there is no fluorescence but the broadness of the bands inhibits the exact assignment of many ingredients. A high fluorescence background experienced for many natural products prevented the recording of Raman spectra for all ingredients, in many instances though the sharp peaks usually associated with Raman spectra make identification easier than with FTIR spectroscopy. Most of the ingredients in the paints could be identified, but it is clear that better results are obtained when more that one technique is used. 相似文献

反映西晋前期政区全貌的《晋书·地理志》中记载了58个县级封国,包括公国、侯国两类。虽然西晋朝廷已设置公、侯、伯、子、男五等爵,但这些封国所对应的爵位,却是位在五等爵之下的一般县公、县侯。各家县公主要是由曹魏宗王降封而来。为县侯者,有功臣、敌国降将、曹魏宗室,还有不少是曹魏时即已受封而入晋后仍保留爵位者。 相似文献

The political economy literature on post-disaster reconstruction tends to contrast ‘disaster capitalism’ narratives denouncing the predatory character of neoliberal rebuilding, and ‘building back better’ policies supporting market-driven reconstruction. This article seeks to provide a more nuanced account, developing the concept of ‘disaster financialization’ through a case study of household-level changes experienced through processes of post-earthquake reconstruction in Nepal. The concept of disaster financialization describes not only the integration of disaster-affected households into the cash-based logic of reconstruction instituted by donors and government authorities, but also the financialization of their lives, social relations and subjectivities. It is a transitive process involving a shift into financialized mechanisms of disaster prevention, adaptation and recovery. Analysing contrasting experiences across three earthquake-affected districts in Nepal, this study proposes disaster financialization as an integrative term through which to understand the simultaneous acceleration of monetization, the leveraging of cash incentives by donors and government to ‘build back better’, and the flurry of financial transactions associated with reconstruction processes. While some aspects of disaster financialization have had negative social impacts, such as debt-related anxieties and a breakdown of voluntary labour exchanges hurting the most vulnerable, the process has taken on variegated forms, with equally variegated effects, reflecting household characteristics and interactions with financial institutions. 相似文献

This article focuses on the various actors in the urban setting who contribute to the increase in the forced mobility of homeless injection drug users and crack smokers in Montréal, Canada. The objective is to analyze who these actors are and how they contribute to increasing this forced mobility from the perspective of homeless injection drug users and crack smokers in relation to three needs : basic needs, acquisition of financial resources, and drug use. One hundred and six semi-structured interviews were conducted among this population. The results indicate that various actors—police officers, community organization, peers, municipal administration, storekeepers, and residents—contribute to the forced mobility of this population in their daily activities. As for their needs, it is when they use drugs, sleep, or loiter that they are more likely to experience events of forced mobility. Police officers are by far the actors who contribute the most to this, often in a repressive way. The role of the municipality is also a determining factor in the daily activities of homeless injection drug users and crack smokers. 相似文献
