Linear enamel hypoplasia is a physical deficiency occurring during the process of enamel formation and it is visible on the crowns of mammal teeth. It can be used to trace physical stresses during life. In this study, linear enamel hypoplasia in samples of pigs from three Neolithic sites in the Wei River valley (China) were recorded and analysed, to investigate the status of pigs at these sites, their living conditions, and furthermore to explore husbandry strategies for pigs during the Neolithic in the valley. The results suggest a domesticated status for pigs in the Neolithic and early Bronze Age. Also the frequency of LEH occurrence for the pigs corroborates a presumed intensification processes of pig husbandry, and the presence of environmental fluctuations during the period are considered. Some evidence also points to the fact that for pig, spring farrowing was the most common reproductive strategy in the Neolithic and early Bronze Age in this region. 相似文献

Sidney Tarrow has identified a ‘cycle of contention’ taking place in Italy between 1966 and 1972; Tarrow characterises the left-wing terrorism of the late 1970s as an after-effect of this cycle. However, there was a second cycle of contention between 1972 and 1979, incorporating the left-wing ‘armed struggle’ milieu alongside a group of related mass movements (notably the ‘area of Autonomia’, the ‘movement of 1977’ and the ‘proletarian youth movement’). The second cycle, unlike the first, was met with repression, and with the exclusion of its ideological and tactical innovations from the political mainstream. The difference between the two cycles relates to the role played by the Italian Communist Party, which functioned as a ‘gatekeeper’ in each case; the party's engagement with the first cycle can be characterised as inclusive, while its engagement with the second cycle was unremittingly exclusive. 相似文献

This paper examines some problematic methodological and ethical issues associated with in‐depth qualitative research with children. The discussion has wider resonance for qualitative studies of young people in ‘rural’ contexts. Particular ethical issues arise when researching with children, which are underpinned by children's relative powerlessness in society. With this in mind, the paper considers substantive strategies to promote ‘empowering research relations’, drawing upon an empirical study with children in primary school spaces. Re‐theorisations of identities and power as fractured, dynamic and contextual, suggest that research is comprised of specific moments or ‘research performances’. It is argued that developing empowering research relations involves negotiating such performances in ways that contest, or transform, dominant societal relations between children and adults. In this paper, I consider some of the specific, embodied performances involved in my research, to expose some of the complexities of power relations and negotiations within space. Bringing to light particular moments emphasises that power relations between children and adults are not reducible to the powerless and the powerful. It is also demonstrated that research performances are influenced and constrained by expectations placed upon adult and child practices in society and institutional spaces, and by researchers' own unconscious reproduction of dominant identities. 相似文献

This study examines the potential socio-spatial impacts of a new series of marine protected areas (MPAs) on fishers in Moorea, French Polynesia. The establishment of the MPAs is contextualized within recent and historical processes of economic development and theories of women in development and gender, culture and development. Seventy adults from three neighborhoods in Moorea were interviewed. Analysis of the data provides new information about the characteristics of fishing in Moorea. Unlike most fishing cultures and communities throughout the Pacific Islands, men and women in Moorea have similar, as opposed to segregated, spatial patterns of fishing activities and fishing methods. The study also points out the potential negative impacts of the MPAs on both men and women, particularly younger and lower-income fishers. 相似文献

The Loch of Clickimin, Shetland, is well known for its broch and associated monuments supposedly of the Bronze and Iron Ages, although the former date is disputed. Pollen, diatom and sedimentological investigations permit fresh insights into the landscape and economic impacts of those who constructed the monuments, reveal that the environs of the site experienced environmental change from Neolithic times onward and provide the first Holocene radiocarbon dates from the immediate locality. The broch-building period witnessed a continuation of pre-existing pastoral husbandry for which heather burning may have exacerbated the natural spread of blanket peat. Initially, no evidence was adduced for local arable activity in the present investigation, and this was thought to be consistent possibly with the low numbers of excavated querns and the absence of cereal macrofossil finds when compared with other Shetland broch sites. The application of ‘rapid scanning’ techniques, however, led to the discovery of a consistent cereal-type pollen representation from Bronze Age times onwards. The discrepancies between the palaeoenvironmental evidence and the environmental and palaeoeconomic inferences made by the excavator of the site are explored. Evidence is presented that both supports and contradicts previous assumptions surrounding an important archaeological site. 相似文献

In this article, we explore the way men and women used the idea of violence to transform their broader political roles in
their desired new Republic. We argue that the espousal of violence, whether or not actually undertaken, became an important
part of the accoutrements of progressive political forces in China at this time. Violent action was perceived as virtuous
rather than villainous among reformers and radicals in the late Qing and early Republic. We demonstrate that the impact and
significance of this turn to violence differed for men and for women. For men, the ability and willingness to take violent
action symbolized a break with the effete literati of the imperial past by their envisaging of a muscular Confucianism; for
women, it provided a platform on which their claims to equal citizenship with men could be performed. The gendered nature
of the virtue of violence within this rapidly changing political context produced unexpected results for both male and female
political aspirants. 相似文献
