The calcareous skeletal remains of various microscopic organisms such as foraminifera and ostracods are a striking feature of thin sections of many archaeological ceramics from the Aegean Bronze Age. While the presence of these calcareous microfossils in pottery has been noted for some time, attempts to utilize them to further the aims of ceramic compositional analysis have been few in number. In the following paper, we take a first detailed look at the occurrence and utility of calcareous microfossils in archaeological ceramics. By presenting selected case studies from the Bronze Age of Crete, we demonstrate the potential of calcareous microfossils, especially the extremely small ‘nannofossils’ and the highly contextual geological information that they contain, in terms of the characterization and grouping of ceramics, the determination of their provenance and the reconstruction of ancient technology.  相似文献

The scientific analysis of ceramics often has the aim of identifying groups of similar artefacts. Much published work focuses on analysis of data derived from geochemical or mineralogical techniques. The former is more likely to be subjected to quantitative statistical analysis. This paper examines some approaches to the statistical analysis of data arising from both kinds of techniques, including ‘mixed‐mode’ methods where both types of data are incorporated into analysis. The approaches are illustrated using data derived from 88 Late Bronze Age transport jars from Kommos, Crete. Results suggest that the mixed‐mode approach can provide additional insight into the data.  相似文献

Given the large impact that domestic violence has on many women's lives, it is surprising that research in this area has largely neglected the ways in which women respond to this problem in different cultural contexts. This article examines variations in Western Samoan women's responses to domestic violence in three different contexts, in rural and urban Western Samoa and in Christchurch, New Zealand. The authors find that processes relating to the individualisation of social relations, changes in women's economic independence, and political mechanisms that provide formal support for battered women go some way to explaining variations in women's responses to abuse in the three contexts. However, the findings rule out any simple link between context and responses to physical abuse and caution us against the naive hope that changes in a single variable will reduce women's vulnerability to violence.  相似文献

When the U.S. Supreme Court Justices took their seats at the beginning of the 2009 Term, the Bench looked different. Gone from the Bench, after nineteen years, was David H. Souter. He returned to his home in New Hampshire, a state he likes enormously. Justice Souter will be missed by his former colleagues and by advocates before the Court, by legal scholars nationwide and by all who follow the Court's work and activities.  相似文献

The effect of quartz temper on the physical and mechanical properties of clay ceramics and the elucidation of the underlying mechanisms that are responsible for these effects are presented here. Characteristics studied included bulk density, open and closed porosity, density of impervious portion and fracture morphology. Mechanical behaviour was studied by measuring energy dissipation during fracture, Young's modulus, initial fracture toughness and strength in flexure. The significant increase in toughness with quartz volume fraction is explained by the development of a model that accounts for the crack distribution around the grains. The archaeological implications of the work are discussed on the basis of all the parameters that might affect the potter's choices of raw materials.  相似文献

This paper presents an integrated passive-active (i.e. hybrid) system for seismic response control of a cable-stayed bridge. Since multiple control devices are operating, a hybrid control system could alleviate some of the restrictions and limitations that exist when each system is acting alone. Lead rubber bearings are used as passive control devices to reduce the earthquake-induced forces in the bridge and hydraulic actuators are used as active control devices to further reduce the bridge responses, especially deck displacements. In the proposed hybrid control system, a linear quadratic Gaussian control algorithm is adopted as a primary controller. In addition, a secondary bang-bang type (i.e. on-off type) controller according to the responses of lead rubber bearings is considered to increase the controller robustness. Numerical simulation results show that control performances of the integrated passive-active control system are superior to those of the passive control system and are slightly better than those of the fully active control system. Furthermore, it is verified that the hybrid control system with a bang-bang type controller is more robust for stiffness perturbation than the active controller with a μ-synthesis method, and there are no signs of instability in the over-all system whereas the active control system with linear quadratic Gaussian algorithm shows instabilities in the perturbed system. Therefore, the proposed hybrid protective system could effectively be used for seismically excited cable-stayed bridges.  相似文献

This review examines the development of research on gender within the broad arena of rural studies. It does so through four main themes: community, work, environment and sexuality. Drawing on work from a range of Western countries, the review shows how an early reluctance to engage with feminist research and work on gender more broadly has given way to a highly active, diverse and rich research direction in rural studies. The review selectively charts key phases in the development of rural gender studies and shows how research has moved from conceptualising rurality as 'container' for the creation, performance and contestation of gender roles to seeing the rural as integral to the actual construction of gender identities and to the ways they are performed and negotiated. As well as highlighting past research areas, the review suggests some directions for the future development of rural gender studies.  相似文献

William Hubbs Rehnquist spent the last thirty-three years of his life as a member of the U.S. Supreme Court, fifteen as an Associate Justice and eighteen as Chief Justice. I met Bill when I was a freshman at Stanford in 1946. He was attending Stanford and working part time as a "hasher" at my dormitory during the evening meal. He amazed all of the young women by carrying such heavy loads of dishes on his tray. Perhaps that is how he learned to carry all those heavy loads in all of the years that followed. He was tall and good-looking, and he had a sharp sense of humor.  相似文献
