Abstract: Our goal in this paper is to identify how recent escalations in immigration enforcement and changes in migration practices affect the ability of the state to continue to serve two of its key “productive” functions: protecting capital accumulation within industry and ensuring the state's own political legitimacy in the eyes of the public. We draw on our ethnographic research on Latino migrant dairy farm workers in Wisconsin to examine the ways in which a group of migrant workers experiences the process of being enforced as “illegal” bodies. We find that migrant dairy workers’ palpable sense of “deportability” articulates with the specific structure of dairy work in ways that make the economically and politically “ideal” migrant: compliant at work and invisible otherwise.  相似文献

Results of analyses of the photoperiod response gene (PPD-H1) and simple sequence repeats (SSRs) in modern landraces of cultivated barley were used as evidence for the mechanism of agricultural spread in Neolithic Europe. In particular, we explored the usefulness of considering adaptive genes as indicators of past selective pressures acting on crops, during their spread through Europe. In some areas, such as the Alpine region, Britain and Scandinavia, we have evidence to suggest that the adaptation of crops to certain climatic conditions may have contributed to the timing of agricultural spread. At the northern fringes of Europe, and in higher altitude locations in central Europe, the introduction of more suitably adapted cereals may have facilitated successful agriculture to trigger agricultural expansion. This research opens up the possibility of investigating other genetic adaptations to climate, which would permit a fuller evaluation of the relative contributions of climate/crop and forager/farmer interactions in the process of agricultural spread.  相似文献

Flemish 15–17th century tapestries are among the most precious testimonies of European cultural heritage. Even in their deteriorated condition, they are still highly valued and exhibited in many museums all over the world. The present state of degradation evidenced by visual assessment in conservation practice, and confirmed with macro-scaled tensile strength tests, reveals the vulnerability of the wool and silk fibres to light exposure.  相似文献

Maxillary and frontal sinusitis, cribra orbitalia and linear enamel hypoplasia were recorded as indicators of nutritional and environmentally related stress in an Early Iron Age (0–260 AD ) population from Sweden. The material comprised the skeletal remains of 99 adults and 45 subadults (aged 20 years and under). Maxillary sinusitis and cribra orbitalia were recorded in the majority of subadults and adults. In contrast, linear enamel hypoplasia was uncommon and occurred mainly in the subadults. In seven cases (12.7%) there was a clear co‐occurrence of periapical lesions and maxillary sinusitis. A significant co‐occurrence of maxillary sinusitis and frontal sinusitis was found in the adults. The least common combination in sex‐determined adults was cribra orbitalia and enamel hypoplasia, only 7.7% exhibiting both lesions. The significantly higher incidence of this combination among subadults suggests an association with life‐threatening conditions. Overall, the results showed that the Early Iron Age community studied suffered foremost from upper respiratory diseases. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

由于"左"的错误和自然灾害,中国在1959~1961年出现了三年经济困难,当时最突出的问题是农业生产遭遇严重挫折,粮食极度短缺。为加快农业生产的恢复,20世纪60年代初,国家制定了"吃饭第一"的方针,要求各行各业支援农业。利用财政手段增加对农业的投入是贯彻这一方针的重要举措。国家财政支援农业的措施主要有两方面:一是减少提取农业剩余;二是直接增加对农业和农村的财政投入。  相似文献

Foraging ranges, migrations, and travel among Middle Holocene hunter–gatherers in the Baikal region of Siberia are examined based on carbon and nitrogen stable isotope signatures obtained from 350 human and 203 faunal bone samples. The human materials represent Early Neolithic (8000–6800 cal BP), Late Neolithic (6000–5000 cal BP), and Early Bronze Age periods (∼5000–4000 cal BP) and come from the following four smaller areas of the broader region: the Angara and upper Lena valleys, Little Sea of Baikal’s northwest coast, and southwest Baikal. Forager diets from each area occupy their own distinct position within the stable isotope spectrum. This suggests that foraging ranges were not as large as expected given the distances involved and the lack of geographic obstacles between the micro-regions. All examined individuals followed a similar subsistence strategy: harvesting game and local fishes, and on Lake Baikal also the seal, and to a more limited extent, plant foods. Although well established in their home areas, exchange networks with the other micro-regions appear asymmetrical both in time and direction: more travel and contacts between some micro-regions and less between others. The Angara valley seems to be the only area with the possibility of a temporal change in the foraging strategy from more fishing during the Early Neolithic to more ungulate hunting during the Late Neolithic–Early Bronze Age. However, the shift in stable isotope values suggesting this change can be viewed also as evidence of climate change affecting primary productivity of the Baikal–Angara freshwater system.  相似文献

湖北郧县直立人遗址研究新进展   总被引:1,自引:0,他引:1  
郧县人Ⅰ号头骨、郧县人Ⅱ号头骨分别于1989年5月和1990年6月出土于中国湖北省郧县直立人遗址。2000年以来中法两国学者对遗址进行了深入研究,在考古学、古人类学、沉积学、微观形态学、地球化学、磁性地层学、地球年代学和孢粉学研究方面取得了一些新成果。研究成果显示遗址的年代在距今984000~780000年之间,两具头骨化石的年代在距今936000年左右,是世界上更新世早期重要的直立人化石之一;郧县人遗址石制品面貌比较古老,是中国南方典型的砾石石器文化传统。  相似文献
