Until relatively recently, studies of bird remains have been regarded as peripheral to mainstream research on early archaeological and palaeontological sites, rather than a potentially crucial factor in the reconstruction of the past environments in which hominids and other larger mammals were present This paper sets out to define the range of ecological information for a site which can be gained through study of the bird bones, using as an example the bones recovered in the excavations at Gorham's Cave, Gibraltar. © 1997 John Wiley & Sons, Ltd.  相似文献

Scientists from the National Institute of Standards and Technology (NIST) worked in a collaborative partnership with archaeologists from the National Park Service's (NPS) Submerged Resources Center (SRC) to develop a finite element model (FEM) of the battleship USS Arizona. An FEM is a computer-based engineering model that calculates theoretical stresses, propagation of force, and shape changes to a structure under loads using thousands or even millions of individual elements whose individual responses are well understood. NIST researchers created an FEM of an 80 ft. (25 m) midships section of the Arizona site to analyze archaeological site formation processes on the sunken battleship, in particular to determine the current condition of the wreck and predict its future strength and structural integrity as it continues to corrode. The NIST's FEM study is one aspect of a larger project under the direction of the NPS, the USS Arizona Preservation Project, whose goal is to determine the nature and rate of corrosion affecting USS Arizona, and to model its long-term structural deterioration. The FEM incorporates findings from other key components of the USS Arizona Preservation Project, such as steel hull corrosion rates, structural surveys of the vessel, sediment compaction studies, and analysis of the concretion that covers the ship's hull, into a single tool that is being used to predict how the wreck will degrade in the future.  相似文献

Multiple osteochondromas is an inherited autosomal dominant condition of enchondral bone growth. The paper undertakes the first synthesis study of the 16 known cases of the condition that have been identified in the international palaeopathological record. It also includes information derived from two newly discovered cases of the disease in two adult male individuals recovered from the Medieval cemetery at Ballyhanna, Co. Donegal, Ireland. The formation of multiple osteochondromas is the best known characteristic of the disease but it also involves the development of a suite of orthopaedic deformities. These deformities, which include disproportionate short stature, inequality of bone length, forearm deformities, tibiofibular diastasis, coxa valga of the hip and valgus deformity of the knee and ankle, are discussed in relation to the archaeological cases. Numerous synonyms for the disease have been used within the various publications produced by palaeopathologists, and this can generate confusion among readers. As such, the paper recommends that in future palaeopathologists should follow the guidance of the World Health Organization and use the term multiple osteochondromas when discussing the disease.  相似文献

Smallpox inoculation was one of the great discoveries of the 18th century and has been written into the grand narrative of medical progress, describing the taming of epidemic disease. Setting the perspective of progress aside, the article explores how this medical innovation was situated in 18th-century society and culture. The aim is to investigate how medical practice was intertwined with social structure and cultural patterns. The article takes its case from a book published in Copenhagen in 1766 by Professor C. F. Rottb?ll, former Head Physician of the Royal Inoculation House in Copenhagen. Being the first medical treatise on inoculation in Denmark-Norway, the book also has a historical section followed by a collection of reports and letters written by a number of other authors from various parts of the kingdom. Through close reading, the article explores how the introduction of the new technique was described in the texts. The reports were written to present practice and discuss cases. In doing so, they also presented a variety of other concerns so that a diversity of aims and intentions are added to the medical ones. The social and rhetorical strategies employed illuminate social ambition and systems of patronage, as well as understandings of history and of truth.  相似文献

This article considers why and how locality influenced feminists' perceptions of colonised women. It does so through an analysis of how militants and novelists linked with the Union Française pour le Suffrage des Femmes (French Union for Women's Suffrage, UFSF) perceived the Arab and Berber women of colonial North Africa. The organisation had branches in North Africa, and thus feminists in Algeria, Morocco and Tunisia are compared to those in France. Where these women lived shaped their understanding of French women's roles in the colonies, along with their opinions regarding the rights to which colonised women could lay claim. Tensions among UFSF members are traced here through the literary figure Elissa Rhaïs, articles in the feminist newspaper  La Française  and correspondence among UFSF members. These sources indicate that while all these French women positioned themselves as mediators of colonialism and women's rights, their precise interpretations of that mediation were consistently influenced by local concerns.  相似文献
