This paper reports the results of excavation at Mugharat al-Kahf (WTN01) in Wādī Tanūf, North-central Oman. It also provides information on the nonmortuary and nonsedentary activities in central Oman during the Wādī Sūq period (2000–1600 BCE), as the subsistence and social arrangements of this period are the subject of much debate. Previous surveys had discovered a substantial amount of Wādī Sūq pottery at the site. This project took forward the excavation for further exploration. The excavation at Test Pit 1 identified Layers Ia and Ib, wherein pottery sherds, charred date stones and other samples for radiocarbon dating were discovered. These prove the cave's occupation during the early third millennium BCE, early second millennium BCE and the Islamic period. The analysis of artefacts and floral remains provided insights into the sojourn, storage and consumption of dates in the cave, and the mobile lifestyle in central Oman.  相似文献

This article offers an interpretation of Kenji Miyazawa’s fairy tales using the theory of material imagination proposed by Gaston Bachelard. Putting Bachelard’s theoretical framework to the test in a totally different culture, the article focuses on the way Japanese fairy tales make use of the four elements of Empedocles. These four elements in turn help to uncover an unconscious source of creative inspiration for Miyazawa, revealing the predominant role of earth in his work.  相似文献

The process and timing of skull removal remains poorly understood by researchers. New archaeological and skeletal analysis from two skeletons from the early Pre‐Pottery Neolithic site of Tell Qaramel, northern Syria, highlights that Neolithic villagers used stone tools to physically decapitate the dead. Drawing upon cutmarks on the axis and the mandible from primary and secondary burials, we employed a scanning electron microscope to document how Neolithic people cut the ligament and its surrounding connecting tissues that bind the cranium with the bones of the axis and the mandible. The position of the cutmarks, especially at the top of the odontoid process of the axis, illustrates the complexities of intentional skull removal. From these and associated burial data, we illustrate that Levantine Neolithic people had specific practical codes for the sequence of skull removal, but given variation in the decomposition of the human body, at times, villagers had to use flint tools for skull removal. This study provides evidence of some of the world's earliest examples of intentional decapitation within human communities. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

As a rule, data to be used in locational analysis are either rounded up or rounded down. Therefore, error is incurred if such location data are used. The objective of this paper is to examine location error and cost error due to rounding in unweighted minisum and minimax problems in one-dimensional continuous space. Several conclusions on rounding effects are obtained by examining the respective mean-squared errors. First, rounding tends to exert more serious influence on the minisum problem than on the minimax problem. Second, in both location problems, the location error shows a pattern that is the inverse of that of the cost error.  相似文献

A human skeleton of the Okhotsk Culture from the Hamanaka-2 site of Rebun Island, northern part of Hokkaido, was found with abnormally large deposits of dental calculus, especially on the right upper 2nd and 3rd molars. This may relate to the early loss of the corresponding right lower molars. Root apex cementum hyperplasia and resorption of alveolar bone due to periodontal disease were also observed; these may have been associated with the calculus. The severe dental calculus and other diseases observed appear to have nothing to do with the subsistence pattern and ethnological background of the Okhotsk Culture, but rather with the individual's poor oral hygiene and digestive dysfunction.  相似文献

A Dingo-type dog skeleton was excavated in Pukapuka Island of the Cook Islands with an estimated age of about 350 years. Luomala (1960) suggested that an investigation of the breed of Polynesian dogs would provide clues to the history of migration of the Polynesians, who domesticated the dogs. The Pukapuka dog skeleton is morphologically similar to the dingo and suggests some racial or economical interchange among Australia and Polynesian islands before contact with western civilization.  相似文献

We develop a variant of the flow interception problem (FIP) in which it is more desirable for travelers to be intercepted as early as possible in their trips. In addition, we consider flows being intercepted probabilistically instead of the deterministic view of coverage assumed in the FIP literature. We call the proposed model the probabilistic minisum FIP (PMFIP); it involves minimizing the sum of the expected distance that each flow travels until intercepted at a facility among placed facilities. This extension allows us to evaluate the effect of facility location under any given value of the interception probability and to apply the model to a variety of situations. We apply the proposed model to an example network by assuming a hypothetical situation in which people gather at a stadium from various nodes on the network, and receive some goods or services on the way to the stadium. We analyze optimal solutions obtained by varying the number of facilities and interception probability. It is shown that the expected travel distance until intercept is greatly reduced by means of a few optimally located facilities under a moderate interception probability.  相似文献
