Bison bison mandibular molars from the Late Plains Archaic kill/butchery sites of Buffalo Creek (Wyoming) and Kaplan-Hoover (Colorado) exhibit significant frequencies of dental enamel hypoplasia (DEH), a defect believed to reflect information about physiological status of individual animals. This study provides a methodology to estimate the ontogenetic and seasonal timing of DEH formation in bison dentition. Integration of these estimates with data from bison life history and grassland ecology allows inferences on age- and season-specific factors exacerbating periodic physiological declines that were recorded in the form of enamel hypoplasias. Differences between assemblages indicate regional variability in grassland conditions, with data from Buffalo Creek pointing to recurrent drought that reduced forage capacity and contributed to physiological stress in bison over two consecutive years. Seasons of physiological stress reflected in the DEH correspond to each of the three kill events at the locality, suggesting that predictability of bison behavior in this location was a critical factor in influencing the seasonal timing and location of repeated hunting episodes. Unlike Buffalo Creek, timings of stress episodes are not consistent with season of death in the Kaplan-Hoover bison assemblage, suggesting that favorable grassland conditions were the primary factor influencing timing of this large single-kill event in order to provision for the upcoming winter. DEH analysis represents a developing approach in the construction of models addressing key aspects of local grassland and bison ecology as well as offers unique insights into the hunting strategies and subsistence decisions of Late Plains Archaic foragers. 相似文献

在新石器时代和青铜时代早期,长城沿线的内蒙古中南部、陕北、内蒙古东南部、辽西等地分布有若干石城带,这些石城带基本上都位于当时农业、半农业文化区的北缘,受到气候环境变迁的影响而南北略有移动,其重要功能之一是为了防御北方民族的南侵。由于这些特点与长城有可比之处,故可称其为长城的"原型"。 相似文献

中国国民党早期军队政工制度的演变:1924-1928 总被引:3,自引:0,他引:3
在孙中山的“党治”理念及苏联“党军”体制影响下,中国国民党于1924年改组后积极倡行“党在国上”、“党在军上”的政治制度,在黄埔军校教导团时代,即仿效苏联红军实施以党代表为中心、以政治部为具体实践单位、辅以自上而下建立党部的三位一体的政工制度。1925年7月改编为国民革命军后,这一体制在黄埔军校生为主体的军队内基本保留。因国共间的猜忌,国民革命军政工制度随着“清党”运动而产生重大变异,党代表制废除,政治训练部地位下降,军队党部更是形同虚设。试图控制军队的国民党,却被以蒋介石为首的军人反控,形成了事实上的“以军干政”、“军强党弱”现象,成为此后影响民国政治走向的一大因素。 相似文献

Monitoring the degree of asymmetry in different parts of the human body can contribute to population studies, as it may be connected indirectly with the social structure, living conditions, and also with biomechanical stress affecting the person. Analysis of asymmetry may also assess preferential use of the right or left of the body during specific activities. This study is based on the measurements of bones of the upper and lower limbs of skeletons derived from the remarkable medieval cemeteries of Mikulčice‐Kostelisko (78 male, 132 female) and Prušánky (66 male, 69 female) (9th–12th centuries AD), and a series of skeletons representing a recent population from Bohemia (143 male, 157 female). The objective was to assess directional asymmetry (DA), fluctuating asymmetry (FA) and antisymmetry (AS) of the dimensions of the evaluated bones, and to use these data to compare the characteristics of the medieval and recent populations. DA was recorded in most dimensions. In the upper limb, the humerus exhibited the greatest expression of asymmetry, and, with the exception of the clavicle, DA was always more pronounced on the right side. Conversely, DA was less prevalent in the lower limb bones. It was more pronounced on the transverse, sagittal and circumferential dimensions of the diaphyses and epiphyses than on the length, and in most cases it was on the left side. The FA values were very low, and almost negligible in relation to the size. Nevertheless, FA was markedly more frequent on the lower than on the upper limb. In contrast to the medieval population, the recent population had higher FA and DA values. Thus, we propose that people from this medieval population were subjected to lower developmental stress than the recent sample. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Managing Heritage in a War Zone 总被引:1,自引:0,他引:1

Threats to the rich Palestinian cultural heritage are many and diverse. They are quite serious and hard to deal with. Some
of them, such as illegal digging and the antiquities trade, are the result of a mixture of past colonial history and internal
and self-inflicted problems, while the Israeli Separation Wall, direct military and settlement activities are present-day
external threats. Up to this very day, they are devastating the country’s heritage, and nothing has thus far been done to
confront them. The present paper intends to discuss those threats and suggests ways to confront them.
Résumé Les menaces mettant en péril le riche héritage culturel Palestinien sont nombreuses et variées. Elles sont très sérieuses et d’un abord difficile. Certaines d’entre-elles, comme l’excavation illégale et le commerce des antiquités, sont le résultat d’un amalgame entre l’histoire post-colonialiste et de problèmes issus des Palestiniens eux-mêmes. Le mur dressé par les Israélien, les interventions militaires et les activités d’implantation dans les territoires occupés constituent actuellement des menaces. Jusqu’à ce jour, ils sont entrain de dévaster l’héritage du pays, et rien n’a été fait pour les confronter. Cet article a pour objectif de discuter de ces menaces et suggère des moyens de les confronter.
Resumen Las amenazas que acechan al rico patrimonio cultural de Palestina son muchas y muy variadas. Son, además, bastante graves y difíciles de combatir. Algunas de ellas, como la excavación ilegal y el comercio de antigüedades, se deben en parte a la historia colonial y a problemas autoinflingidos, mientras que el muro de separación israelí y las actividades militares y coloniales directas son las amenazas externas de la actualidad. Hasta hoy, han estado destruyendo el patrimonio del país y nada se ha hecho para evitarlo. En este trabajo se pretende analizar estas amenazas y sugerir medios para combatirlas.相似文献

Majority of contemporary Chinese historians have been employing a conceptual framework focusing on the difficulty of capitalistic
development in China to analyze the historical trend and potentials of late imperial China. This approach based upon the presupposition
of viewing the pattern of Chinese history as abnormal reflects with the remaining influence of the Western-centric methodology.
Further, based upon a “normal” point of view, seven fundamental, irreversible, and systematical changes to the Ming society
could be identified. By conclusion, China in the Ming period was transforming into an imperial agric-mercantile society. This
process proves that late imperial China was not stagnate society without “history,” meanwhile, its pattern of development
was clearly not identical to the Western style modernization progress.

京军本为守御京师(畿)而设,但随着政局的稳定和社会经济的发展,皇亲贵戚的生活越来越奢华,京城内的工程修建越来越多,大批京军被抽调借拨到建筑工地,一部分京军竟然演变成职业建筑工人。京军参与修筑的建筑物主要是宫殿庙宇。京军修筑虽然组织方便、节省费用,却严重影响到军队的战斗力,加速了军队的衰败,这也是明朝灭亡的一个重要因素。 相似文献
