A methodology is described by which spatial patterns of land use were reconstructed from pollen analyses on anthropogenic sediments at a recently excavated early Neolithic timber ‘hall’ in north east Scotland. The anthropogenic sediments were from a deep, small diameter pit within the building. They present numerous taphonomic and interpretative challenges to the analyst, but from this type of deposit, the power to estimate quantitatively the vegetation structure around the archaeological site makes such difficult deposits very significant. A rigorous methodology is firstly described, therefore, by which confidence in ecological interpretation can be established. Secondly, the source of pollen in the deposit is evaluated. Thirdly, the possible pollen source area and structure of the surrounding vegetation are estimated by quantitative simulation modelling. Finally, these analyses are compared with region-scale pollen analyses from nearby conventional wetland deposits with much larger pollen source areas. The pollen assemblages recovered probably reflect land uses adjacent to the ‘hall’ and up to 2.5 km around. Cereal cultivation was the most important land use immediately around the ‘hall’, possibly grown between stands of scrub Corylus (hazel) woodland. These intensive but local-scale land uses cannot be discerned in region-scale pollen analyses. 相似文献

This study presents the results of multi-element analysis of weak-acid extractions of 953 soil samples collected by coring on and around pre-historic village sites on two islands, Sanak and Amaknak, in the eastern Aleutians. Concentrations of aluminum (Al), barium (Ba), calcium (Ca), iron (Fe), potassium (K), magnesium (Mg), manganese (Mn), phosphorus (P), strontium (Sr), titanium (Ti), and zinc (Zn) were determined using an inductively coupled plasma-mass spectrometer (ICP-MS). Resultant elemental signatures allow the identification of site features and organization in the absence of large-scale excavation. All the archeological sites showed similar and distinct chemical signatures regardless of the several thousand year date range of the sites or the length of time a site was occupied. However, intensity of occupation does appear to affect concentrations of elements. Site features such as houses, house berms, house floors and middens had distinct anthropogenic signatures and could be distinguished from one another. This approach may be used to identify sites that do not have distinct surface features and to target areas for excavation. 相似文献

This essay examines the work of the Joint Committee on the Conduct of the War, a joint select committee of investigation formed by Congress during the American Civil War. During its tenure in the 37th and 38th sessions of Congress, the Committee investigated almost every aspect of Union military operations; however, its principal concern was the examination of Union military defeats. Members of the Committee on the Conduct of the War were influenced by the notion of inevitable Union victory. As self‐made men who had achieved a degree of success in the emerging market economy of nineteenth‐century America, Committee members exemplified the period's predominate concept of masculinity. Also skeptical of military science and distrustful of the United States military academy at West Point, the Committee showed a marked preference for volunteer soldiers and officers throughout the war. Believing that West Point generals who endorsed strategic maneuver were cowardly and disloyal, Committee members were frequently critical of regular army officers in their investigations. Confusing the rhetoric of ‘hard war’ with military competence, the Committee's disdain for military education caused it to endorse incompetent military leadership and advocate mediocre generals for high command. 相似文献
