Urban green space is a key subject of actual urban negotiation processes on how the city shall develop. Visions of the ideal city are reflected in the meanings currently ascribed to urban gardening. Thereby the relation between human and nature as well as between build and natural environment in the city plays a central role. Results from different Swiss cities show that allotment gardens as well as newer forms of urban gardening are oscillating between a compensatory and a complementary understanding of nature, and they equally combine the desire for pristine nature with the demand for functional green space in the city. 相似文献

Mapungubwe (AD 1220–1290) is generally regarded as the first urban centre in southern Africa, functioning as the seat of power for an extensive but short-lived polity. More than 80 years of excavations here, and at its nearby predecessor K2 (c. AD 1000–1220), resulted in a substantial assemblage of material remains from elite and commoner contexts. This assemblage includes a large collection of worked bone objects, such as needles, awls, tubes and objects of personal adornment. Of particular interest are the bone arrowheads and link-shafts, of which a significant number of specimens were found complete and intact. Such quantities of well-preserved worked bone objects are unique in the archaeological record of the region. The worked bone assemblages from these two sites provide a rare opportunity to study multiple components of the production process as well as the use context of bone objects. In this paper, we characterise the K2 and Mapungubwe worked bone industries through various morphological, technological, use-trace and contextual approaches and discuss the significance of these aspects in terms of raw material selection and manufacture and archaeological use context. In particular, this study shows the complexity of these worked bone industries over time. 相似文献

Located in northeastern South Africa in the Kruger National Park, the wild-dominated faunal assemblages at Le6 and Le7 allow for a site-level examination of the treatment of wild species within the highly variable spectra of Early Iron Age animal use. Looking at hunting beyond pure subsistence choices, this paper couples traditional morphological analysis with taphonomic analysis and theoretical frameworks of intensification to ask new socially focussed zooarchaeological questions of these assemblages. Through this, both the procurement and processing methods utilized at Le6 and Le7 are identified and the significance of these choices is discussed. In so doing, the paper addresses possible specialization in both the hunting and the processing of large wild mammals. The socio-economic implications and potential drivers of these faunal choices are then considered within the broader context of the southern African Early Iron Age, and a potentially new faunal use strategy and site type are introduced. 相似文献

Research projects undertaken in the Cantabrian region since 1980 have produced new, high-quality information about the neolithisation process(es) in this area. It is now necessary to review this archaeological information and test the main hypotheses put forward to explain it. This paper presents an update on the archaeological evidence (sites, chronological dates, archaeozoological, archaeobotanical and technological information) for the early Neolithic in the Cantabrian region. It summarizes recent research on neolithisation in the region, and assesses the impact of this process during the early Neolithic, and its later consolidation. Although the available information is still incomplete, it is now possible to identify the focal point of the introduction of elements characteristic of the Neolithic way of life in the region. Current evidence suggests that it is in the eastern sector, where the earliest arrival of domesticates and new technologies such as pottery has been attested. The existence of continuities—such as sustained reliance on hunting and gathering and the coexistence of old and new funerary rites—suggests the persistence of native populations, which gradually participated in the neolithisation process after an ‘availability phase’. 相似文献

Methodological advancements in geoarchaeology and spatial and chronological modeling are opening new avenues to interpreting large coastal shell-bearing sites. We document the developmental histories of two such sites around Prince Rupert Harbour, Canada, using systematic percussion coring, intensive radiocarbon dating, and 3D surface mapping with Total Station and LiDAR. We also re-analyze a third site (Boardwalk/GbTo-31) excavated and radiocarbon dated in the 1960s, 1970s, and early 2000s using archival field notes, site maps, and stratigraphic profiles georectified using LiDAR. We map the natural landform beneath the sites and document the degree to which people physically modified landforms through the deposition of massive shell accumulations. We model site development through time and space and use accumulation rates and OxCal modeling to test for intentional deposition events. All three sites demonstrate complex and heterogeneous occupation histories. At each we identify instances of very rapid deposition that effectively terraced and extended parts of the natural landform to create places for constructing houses, though these episodes take place within longer histories of slower quotidian deposition. The anthropogenic modifications to the coastline in this area are the result of these mixed processes associated with long histories of occupation. 相似文献

This article explores the linguistic experiences of transnational soldiers, using the Spanish Civil War as a case study. It argues that communication difficulties provoked by linguistic diversity within the Republican war effort and particularly within the International Brigades, caused the high command to move from a utopian, internationalist policy to a more pragmatic approach. The article evaluates the role played by language intermediaries in this evolving policy and in the wider Republican war effort. Finally, it argues that soldiers grassroots experiences of language contact forged new linguistic forms which underlined a strong sense of shared purpose and identity. 相似文献

In 1940, Gretchen Cutter and a WPA crew conducted excavations in the Mound Wio5 at the Fisher site in Will County, Illinois. We examined those materials as part of our reanalysis of the Fisher site excavations by George Langford and the University of Chicago. The mound’s material culture correlates with the Des Plaines phase but contains strong connections to the east, especially with Albee phase mortuary practices. Calibrated 14C dates and Bayesian modeling place the Des Plaines phase as contemporary with the Mound Wio5 mortuary’s primary use during the ninth to eleventh centuries. There is isotopic evidence of a mixed C3/C4 diet with some maize consumption. Mound Wio5 represents the only Terminal Late Woodland collective mortuary facility currently known in northeastern Illinois. The identification of such multigenerational communal Terminal Late Woodland mortuary practices lends support to the contention that they provided the cultural base for the emergence of the distinctive Langford Tradition accretional mortuary mounds. 相似文献
