This examination of the planning structure within the Canton of Zürich has indicated that many of the problems, such as adequate public transportation, the provision of land for industry, and the preservation of land for recreational use overlap existing political boundaries. The solutions, to be effective, must be carried out in a co-ordinated and integrated fashion among the city, the regional, and the cantonal planning groups. Much is being done at all levels to ensure that the future growth of Zürich and its surrounding region will take place in an orderly, aesthetically satisfying fashion. Certainly many serious problems remain to be solved. Nevertheless, the development of Zürich from a Roman settlement to one of the world's most important industrial, financial, commercial, and cultural centres has been accomplished with a minimum of destruction to the city's beautiful site. The preservation of the natural environment is a blessing for the city's inhabitants, having economic  相似文献

High-resolution stable oxygen isotope analysis of the bivalve Saxidomus gigantea from shell midden sites was applied to identify seasonal patterns of resource procurement on the central coast of British Columbia, Canada. A total of 90 archaeological shells were examined from eight distinct sites spanning a 4500-year period. Combining micro-growth pattern analysis with high-resolution stable oxygen isotope sampling allows for a precise season of collection to be determined in estuarine bivalves recovered from archaeological sites. The results of the stable oxygen isotope analysis provide insights into seasonally structured harvest of S. gigantea (butter clam), which is associated with different types of sites. The results show a variety of patterns, including multi-seasonal collection, intensive seasonal harvesting and casual, supplemental use of butter clams at different locations.  相似文献

Techniques are described for extracting circular rock features from landscapes dominated by clasts of the same type from which cultural features are composed, using as a test case a large stone circle residential site in western Wyoming, USA. Methods consist of point plotting all relevantly-sized culturally and naturally-deposited clasts in the field and identifying potential cultural features using point density analyses tools in ArcGIS. Potential rings are either accepted or rejected as cultural features by comparing clast frequency, density and distribution in internal, feature-ring, and external spatial buffers to ethnoarchaeological data recording stone circle size and morphology and to similar data generated from a control sample of off-site, naturally-occurring clasts. The results of the analysis are used to discuss group size, mobility type, and duration of site occupation and to explore problems of assessing such at surface archaeological sites resulting from palimpsest-type site formation processes.  相似文献

Secondary refuse disposal behavior is structured by three major concerns in the Maya Highlands: economy of effort, potential value of refuse, and potential hindrance by refuse. According to the needs of each household and the nature of the refuse, material slated for discard may be sorted and dumped in separate locations, within or outside compounds. Archaeologists should be aware of this refuse structure in seeking specific types of refuse as well as in comparing refuse from households, or other types of excavational units. At the household level, recognition of the toft area (the area immediately surrounding the household and related outbuildings) is especially important in acquiring representative samples of “hard” types of refuse. Analysis of neighborhood dumps is strongly advocated as one of the more economical, meaningful, and representative ways of dealing with refuse accumulations. Because of several randomizing and dispersive processes operating at the household level, as well as sample size considerations, simple diversity measures are recommended for comparing household assemblages.  相似文献

Innovation in judicial administration has proceeded slowly for many reasons. The attitudes of judges not-inclined by training toward management, the tradition of Judicial independence, and the separation of powers are examined as contributing factors inhibiting judicial modernization. Federal Judicial reform has defended historically upon the leadership of a Chief Justine of the United State? willing to use the office to dramatize and promote the issues. The most recent period of dramatic change in judicial administration, from 1969-1981, is reviewed with a focus upon the strategies for change employed by Chief Justice Warren E, Burger.  相似文献

Recent archaeological excavations on San Nicolas Island, located off the coast of southern California, revealed the remains of a double dog burial interred sometime during the 13th and 14th centuries. Two carefully laid to rest and possibly sacrificed juvenile, female domestic dogs (Canis familiaris) between the ages of 1 and 6 months were found within a Native American village. Digestive tract residues include burned and unburned fish and marine mammal bone that suggest scavenging behavior or direct feeding by humans. Breed classifications place it between the Short-Nosed Indian dog and the Plains-Indian dog, likely representing a cross between those and other varieties of North American dogs. Comparisons with other dog burials from archaeological sites across southern California suggest commonalities and possible cultural linkages.  相似文献

Evolutionary ecology is a theoretical framework that has been widely applied to problems in human evolution and prehistory. Because the approach often focuses on how behavioral adjustments to changing socio-ecological conditions create novel selective pressures that in turn drive other changes in morphology and behavior, it draws on the same evolutionary logic that underlies niche construction theory. We illustrate here the important role that niche construction has played in archaeological applications of evolutionary ecology with two detailed case studies: one from Late Holocene hunter-gatherer populations in Central California and one from Mimbres-Mogollon agriculturalists in New Mexico. These examples illustrate that evolutionary ecology-based approaches, with an emphasis on formal predictive modeling, allow for the incorporation of niche construction as it affects model parameters with reference to specific problems involving past behavior. Further modeling and empirical applications will expand the synergies between these complementary approaches and advance our understanding of the human past.  相似文献
