Primary sources from the end of the Bronze Age have long been read as suggesting a time of chaotic transition, particularly with regard to threats from the sea that the established powers had no means of combatting. While the scale and severity of seaborne attacks seems to have increased in the late 13th century, these were not in themselves new phenomena, as a state of maritime threat seems to have been a constant for coastal polities and mariners in the Late Bronze Age eastern Mediterranean. However, a combination of internal and external factors in the late 13th and early 12th centuries combined to make these attacks more effective than they had been in the past, and polities more vulnerable to them. These included the rapid spread of improvements in maritime technology, particularly from the Aegean and the Levant, via high–intensity ‘zones of transference’, as well as an increase in the scale of ship–based combat operations, due in part to the displacement of people during the Late Bronze Age collapse. This paper addresses this in two parts, beginning with the ‘background’ evidence for a constant state of maritime threat in the centuries leading up to the end of the Bronze Age, and concluding with the ‘foreground’ evidence for zones of transference and the transmission of groundbreaking elements of naval technology in the years surrounding the Late Bronze–Early Iron Age transition. 相似文献

AbstractThis article examines advanced ages at death in a historical population in northern Sweden between 1780 and 1900. The source material used is a set of data files from the Demographic Data Base at Umeå University supplemented with the search tool Indiko. The belief that the Sami died at very old ages was tested, and life tables and values of remaining life expectancies at older ages were calculated. The information of the age at death was analysed using a model containing four levels of certainty. The analysis reveals that the Sami did not live to extreme ages. The analysis also reveals large differences between the parishes concerning extreme longevity and correctness of age at death. 相似文献

While some geographical surveys on marriage behaviour concern general marriage patterns and family systems, there are other discussions on regional variations in marriage within specific countries. This article belongs to the latter tradition, charting the regional differences in ages at marriage in Sweden from 1870 to 1900, and exploring potential determinants of the regional variation. The study builds on Sundbärg's division of Sweden into three main demographic regions, the subsequent Swedish research, and the historical-demographic studies on the determinants of marriage. The results do not fit perfectly into Sundbärg's geography but find a basic divide between the west and east/north of Sweden, mean ages at first marriage being one to one-and-a-half years higher in the west. Social norms and socioeconomic structure seem to have influenced the timing of marriage. At county level, family farming and crowding/competition over land and tenure were typically associated with later marriages, while commercial agriculture and a more diverse economy were correlated with a lower average marriage age. Also, in counties where real wages were higher, marriages usually took place earlier. Finally, results indicate that counties characterized by more secular and tolerant values were on average associated with earlier marriages. 相似文献

西部地区农户经济的空间差异及其发展对策 总被引:2,自引:0,他引:2
西部不同地带生态条件的优劣差异决定了西部地区农户经济的空间差异,劣等、中等、优等三类生态条件相应地发育出贫困、温饱、富裕三类群落的农户经济。西部各类农户经济的发展有着不同困难,贫困群落农户脱贫面临人口压力大与生态环境脆弱矛盾突出,及农户人均财政负担重,财政支农能力差的困难,已得温饱的农户面临收入与文化素质低、可带动农户从事产业化经营的企业少的困难,富裕农户面临生产要素流失严重,制度创新滞后的困难。由政府主导,以多种手段、方式带动贫困农户脱贫致富;扶持建立农业合作经营组织,促进已得温饱农户发展农业产业化经营;以制度创新推动富裕农户经济的进一步发展,是应采取的针对性对策。 相似文献

Comparing methods for analysing mortality profiles in zooarchaeological and palaeontological samples
T. E. Steele 《International Journal of Osteoarchaeology》2005,15(6):404-420
In this study, I examine three methods that are currently used for comparing mortality profiles from zooarchaeological and palaeontological samples: (1) histograms with 10% of life‐span age classes; (2) boxplots showing tooth crown height medians; and (3) triangular plots of the proportions of young, prime and old animals. I assess the advantages and disadvantages of each method using data collected on two samples of Northern Yellowstone elk (Cervus elaphus nelsoni) with known, or cementum annuli‐determined, ages at death. One sample was hunted by wolves (n = 96), and the other was hunted by recent humans using rifles (n = 226). I tested each method with the known or cementum annuli age distributions and with age estimation techniques appropriate for archaeological assemblages. Histograms are best used when the relationship between dental eruption/attrition and age is well established so that individuals can be confidently assigned into 10% of life‐span groups, and when more than 30 or 40 individuals are present in the assemblage. Boxplots employ raw crown heights, thus removing the error introduced by assigning specimens to age classes, and therefore they allow the analysis of species where the relationship between dental eruption/attrition and age is unknown. Confidence intervals around the medians allow samples to be statistically compared. Triangular plots are easy to use and allow multiple samples and species to be considered simultaneously, but samples cannot be statistically compared. Modified triangular plots bootstrap samples to provide 95% confidence ellipses, allowing for statistical comparisons between samples. When possible, samples should be examined using multiple methods to increase confidence in the results. Copyright © 2005 John Wiley & Sons, Ltd. 相似文献

传承与变异——传统文化对旅游开发的应答 总被引:17,自引:0,他引:17
地方性的传统文化是旅游开发的重要资源,是传统地区旅游业赖以发展的源泉,传统文化的开发、利用促进了传统地区经济和社会的发展。但发展旅游又往往使传统地区过快地抛弃传统,在经济利益的牵动下传统文化发生非正态变异。本文结合案例研究对传统文化如何应答旅游开发所带来的影响进行了探讨,试图对传统文化在旅游开发和现代化过程中的传承、保护问题提出一个解决的途径。 相似文献

本文经类型学研究,将辽东地区两周时期流行的双房式陶壶分为三期,并对年代进行了讨论.在此基础上,通过对其内涵与外延的把握提出三点认识:1.双房式陶壶的祖型可追溯到庙后山文化,在以后的发展过程中逐渐形成以太子河、浑河为中心,分布范围遍及辽东地区具有显著时段特征的一种考古遗存.2.将双房式陶壶分为A、B两系,认为它们是同源陶壶谱系的两个发展序列.3.所谓"美松里"陶壶,是双房式陶壶自西周中晚期发生分野以后,向东流入西北朝鲜地区发展的一支.同时这种陶壶的北传,还对西团山文化产生了较大影响. 相似文献
