Using incremental patterns in tooth cementum is a powerful tool for age assessment. Recent developments have shown that the method has a large potential as an indicator of the season of death of the individual in question. In this paper, the results of a study comparing thin sections of teeth of the modern Hardangervidda reindeer population to those of Iron Age, eleventh, and thirteenth century reindeer hunting stations from the same area are presented. The tooth wear stages were compared to the actual age of the individual (based on the number of incremental lines and the age at eruption). It was established that in the studied reindeer populations wear stages sometimes result in too low an age estimate. Having identified the start of the period of deposition for rest lines in the modern reindeer population as early autumn and winter, analysis of the outermost layer in the tooth cementum at the archaeological sites points to a prolonged hunting season in the thirteenth century, while in the earlier phases hunters were probably present on fewer and shorter visits.  相似文献

This article seeks a queering of research and policy in relation to natural disasters, their human impacts, management and response. The human impacts of natural disasters vary across different social groups. We contend that one group largely absent from scholarly and policy agendas is sexual and gender minorities, or lesbian, gay, bisexual, transgender/transsexual and intersex (LGBTI) populations. To demonstrate that these minorities have particular experiences that need to be addressed, we critically review five case studies that comprise the limited scholarly and policy research on LGBTI populations in disasters to date. Building on this, we offer some specific ways forward for queer disaster research that accounts for the vulnerabilities, needs and resilient capacities of LGBTI populations. In doing so, we recognise and urge researchers, policy-makers and aid agencies to acknowledge that LGBTI populations are not homogeneous and have different needs wrought by intersections of socio-economic resources, gender, race/ethnicity, age and regional or national location.  相似文献

The extent to which North Atlantic Holocene climatic perturbations influenced past human societies is an area of considerable uncertainty and fierce debate. Ireland is ideally placed to help resolve this issue, being occupied for over 9000 yr and located on the eastern Atlantic seaboard, a region dominated by westerly airflow. Irish bog and lake tree populations provide unambiguous evidence of major shifts in surface moisture through the Holocene similar to cycles recorded in the marine realm of the North Atlantic, indicating significant changes in the latitude and intensity of zonal atmospheric circulation across the region. To test for human response to these cycles we summed the probabilities of 465 radiocarbon ages obtained from Irish archaeological contexts and observe enhanced archaeological visibility during periods of sustained wet conditions. These results suggest either increasing density of human populations in key, often defensive locations, and/or the development of subsistence strategies to overcome changing conditions, the latter recently proposed as a significant factor in avoiding societal collapse. Regardless, we demonstrate environmental change is a significantly more important factor in influencing human activity in the landscape than has hitherto been acknowledged.  相似文献

This study examines possible morphological variation in the knee joint of Homo sapiens with increasing age in ostensively healthy and non‐pathological distal femora and proximal tibiae. Throughout the lifetime of each individual, the hard tissue of the knee undergoes considerable remodelling as a response to biomechanical stresses, changes in bone microarchitecture and reduction of bone mineral content as a concomitant of ageing. The knee is also subject to greater levels of degenerative joint disease than any other joint. If death occurs whilst such diseases are in the earliest stages, initial bone changes may not be visually obvious in museum specimens. If such specimens are used for comparative analyses, it is hypothesised that changes might render it problematic if all ages are conglomerated into discrete samples. This study therefore investigates the degree to which the distal femur and proximal tibia change shape during ageing and, if changes are present, whether they are expressed similarly in males and females. It also examines whether changes are of greater magnitude than those morphological differences which might exist between populations. In an example population of African‐Americans, results indicate that there is a statistically significant difference in shape between age groups and those differences become progressively greater between the youngest and oldest adults. Results also show that although morphological variation caused by ageing is apparent, those shape differences attributable to sexual dimorphism are more powerful. When two additional populations are analysed jointly with the African‐Americans (Caucasian Americans and the European Spitalfields sample), results indicate that inter‐population shape differences are considerably greater than differences caused by increasing age. Results imply that it is justifiable to combine specimens of all ages into discrete samples for comparative purposes. Copyright © 2007 John Wiley & Sons, Ltd.  相似文献

Pots as tools is a concept that has been widely accepted and developed since Braun’s classic 1983 publication. However, in northeastern North America archaeologists continue to use pottery primarily as an aid to culture history and research problems based thereon. In central New York State it has been postulated that a change in pottery forming technique heralds the onset of Iroquoian pottery traditions at around AD 1000. Empirical data on pottery forming and two other pottery traits do not support this postulation. Rather the trends in these traits are consistent with social learning theory and changes in mobility and population aggregation. Following Engelbrecht (1999, 2003) we suggest that a more fruitful approach to understanding the evolution of northern Iroquoian groups is to be found in ethnogenesis theory as described by Moore (1994, 2001).  相似文献

The aim of this paper is to present and discuss empirical evidence on the dynamics of occupation and site formation processes from contemporary mobile campsites in Northwest Siberia. The questions posed are derived generally from archaeological studies of Upper Paleolithic record in Europe. We document the active Nenets summer camps at lakes and the abandoned winter and spring camps in the open tundra and the forest tundra. Analysis of the floral and zoological resources shows that plant resources and fish are available predominantly in the summer while reindeer are abundant in these regions in fall and winter when they return from summer pastures further north. When natural resources are not available, groups supplement with food purchased at shops. Within these living camps, “structures évidentes” and “structures latentes” of classical French paleoethnology cannot be distinguished as clearly as at Upper Paleolithic sites: and architectural remains, ash from hearths, and other objects may be removed from the central areas towards the site peripheries. However the investigated camps preserve a discrete structure with interior living areas (including children’s playgrounds), exterior areas with evidence of reindeer carcass processing, woodworking, and other activities, peripheral toss zones, and dispersed activity remains in the surrounding landscape.  相似文献

ABSTRACT

Thailand’s population is aging rapidly and the number of older adults suffering from health limitations is expected to increase. Making use of several rounds of the Survey of Older Persons, we look at the education-specific prevalences of three health indicators over time and find a positive education gradient for difficulties with ADLs and poor self-rated health, but not for functional limitations. Combining these age-, sex- and education-specific prevalences for each indicator with population projections up to 2050, we see a lower projected number of persons with difficulties with ADLs or bad health as compared to an approach when we only account for differences by age and sex. Still, irrespective of the approach taken, we project a significant increase in the number of persons 50+ that have at least one ADL difficulty, at least one functional limitation or suffer from poor health. Our results provide estimates for future care needs and illustrate the possibly preventive effect of education.  相似文献

构造了一个由数量老龄化、结构老龄化和密度老龄化三个指标所组成的综合老龄化指数(CAI),并建立了一套人口老龄化空间类型划分方案,运用多尺度空间自相关分析对长春市人口老龄化空间的时空演变及空间类型进行研究。结果表明:①长春市近10年出现了老年人口郊区化的趋势,人口老龄化空间的“中心-边缘”分布格局在10年内没有发生显著改变,但空间扩散趋势十分明显,东部和南部近郊区出现了明显的人口老化趋势。②长春市形成了残留老化、集聚老化、自然老化和集聚稀释四种不同的人口老龄化类型区。城市核心区和远郊区形成以非老年人口大量流失为基本特征的残留老化型地区,而近郊区则形成以年轻人口大量涌入为特征的集聚稀释型地区,人口老龄化空间整体上呈现出一种城市中心区和远郊区的老化程度高于近郊区的夹层结构。  相似文献
