The range of stones cast by slings used in the past is debated. In the Central Andes, slings are asserted to be important weapons of prehispanic war, and have been recovered archaeologically. Rolled river cobbles and stones presumed to be slingstones found at fortified hilltop archaeological sites are presented as evidence that slings were used at these fortifications. Yet sling use has not been adequately tested at hillforts. Experiments conducted in Europe by a novice slinger have attempted to illuminate the range of sling cast stones at ancient hillforts. Data acquired from native slingers is necessary to more accurately assess distances achieved by projectiles launched by slings. We present data from sling experiments carried out in Puno, Perú among Quechua-speaking herders who are experienced slingers. The results demonstrate that a prior model of the maximum theoretical distance of sling cast stones underestimates their range. Results also show significant differences in the use of slings by men and women, and by different age groups. These new data permit a better approximation of warfare that has bearing on our interpretation of fortified sites. 相似文献

This article examines gendered discourses of shell shock inBritain during the First World War. Located within the contextof the ideas about shell shock as a form of male hysteria putforward by Elaine Showalter, it examines the ways in which thecontemporary discourses of soldiers, medical professionals andpopular novelists used ideas of maturity and self-control tounderstand a condition that appeared to undermine both the wareffort and national masculinity. It argues that contemporaryunderstandings of authority and maturity helped to normalizeshell shock as a medical condition, thereby lessening its perceivedthreat to society. 相似文献

The thermoluminescence phenomenon has been used for pottery dating and radiation dosimetry for sixty years and for forty years
has been applied to the study of meteorites, being successful in quantifying metamorphic histories and providing new insights
into terrestrial age and orbits. Here we review some of the fundamental properties of thermoluminescence with particular focus
on the study of small extraterrestrial particles. We suggest that natural TL data can be used to identify the burial and release
history of cometary particles and that induced TL measurements can provide in-sights into the mineralogy of particles (even
when largely amorphous) and the metamorphic history of those particles. We illustrate the use of TL to study small particles
by describing recent studies on micrometeorites and 10–100 μm fragments taken from the matrix of a meteorite Semarkona which
is type 3.0 ordinary chondrite. 相似文献

The Germans from Russia are a prominent settlement group in the rural landscape of Saskatchewan. Perhaps because they came incrementally, by chain migration, rather than by organized group colonization, they compose an ethnic group little noticed by historians. Also, their immediate origins are divided, inasmuch as earlier German-Russian immigrants came directly from Russia, whereas many twentieth-century German-Russian immigrants came to Canada from the United States, mainly from North Dakota and South Dakota. This article offers the first focused, scholarly historical treatment of German-Russian immigration and life in Saskatchewan. Drawing on oral histories collected with the support of the Faculty Research Program of the Canadian Embassy, it focuses particularly on growing up German-Russian on the prairies, positing a German-Russian ethnic identity distinct both from neighbor immigrant groups in Saskatchewan and from origin communities in the United States. 相似文献

Leonardo Bufalini's plan of Rome (1551) was the first printed map of the Eternal City and a landmark in the history of city plans. This article fills several lacunae in the scholarship on the map by reconsidering its intended function and audience and by situating it at the intersection of technical and antiquarian endeavour in sixteenth‐century Rome. At issue are Bufalini's methods for making the map, along with the distinctive combination of practical and scholarly interests that motivated him. The anomalous status of Bufalini's plan in the realm of popular printed imagery of the city signals, moreover, that the Renaissance audience had a marked preference for pictorial city views over maps. 相似文献
