Primary questions regarding the foraging behaviour of the first hunter–gatherers who colonized the New World are how they found, procured and utilized high‐quality raw materials for manufacturing stone tools. In this paper, we present evidence from the late Pleistocene site of Cueva Bautista in the highlands of south‐western Bolivia, which demonstrates that a substantial portion of the recovered stone tool assemblage originated in Cerro Kaskio, a recently discovered obsidian source located 15 km south‐west of the site. In addition to describing the geological and geochronological setting, we provide the first geochemical characterization of the Cerro Kaskio source by means of instrumental neutron activation analysis and energy‐dispersive X‐ray fluorescence. Supported on the technological analysis and archaeometric sourcing of the obsidian lithics found in Cueva Bautista, we discuss the nature of the procurement strategies practised by the earliest mobile hunter–gatherers who explored and colonized the Andean highlands. We conclude that opportunistic lithic resource procurement was probably an important component of the first foraging societies that explored the highland Andes. 相似文献

Expanded border enforcement has made unauthorised migration to the US more risky, costly, and prone to failure. Research on the material consequences of border enforcement for migrant‐sending households in Central America reveals that the economic hardships enforcement exacts on migrants at times diminishes enforcement's desired deterrent power. Heightened risks have driven up the cost of migration and pushed many to fund their trips through loans. Consequently, migrant detention, deportation, or death can result in poverty and privation for indebted households and the seizure of loan collateral, typically homes and land, in turn prompting crises in household reproduction. With a US wage the most viable means to ameliorate economic hardships, enforcement outcomes push some to return migration. Our findings suggest that US border enforcement efforts at times perpetuate the very unauthorised migration they seek to impede, while also helping to reproduce the border itself by deepening the marginalisation that drives migration decisions. 相似文献

中共中央和共产国际在开除陈独秀的原因和如何开除陈独秀的问题上发生分歧和冲突,主要表现在共产国际远东局想给予尽量多的机会和时间,要求陈独秀承认错误,希望他继续保留在党内;共产国际远东局最后同意开除陈独秀,主要是因为陈独秀在中东路事件上否定了"保卫苏联"的立场,不能容忍.而中共中央政治局则更看重于陈独秀转向托派对本国革命和共产党的影响以及他反对中共六大路线. 相似文献

Early Bronze Age society in Central Europe is often depicted as a society dominated by males. It is suggested that archaeological evidence is not always in agreement with this view. This study reports the analysis of mortuary variability at the Early Bronze cemetery Rebešovice in Moravia (Czech Republic) that uses computer-intensive resampling techniques. The results indicate that there are only minor differences in the mortuary treatment of females and males. There is neither a qualitative restriction of body treatment and objects buried with males, nor a quantitative emphasis on burials of males. In fact, burials of females are equipped with a higher number of bronze artifacts. Funerals of females were at least as significant social events as the funerals of males. We argue that the model of a male dominated community that used this cemetery is unwarranted. These findings do not refute the existence of gender-specific activities and roles that may be valued differently, but instead suggest that both females and males had access to resources from which they could draw power. 相似文献

We use the built environment of residential sites (house form and community layout) to investigate the effects of increasing regional integration at the level of the community in middle-range societies. We consider spatial data on house form, arrangement of residences within settlements, site location, and organization of non-residential spaces to reveal specific social phenomena linked with pan-regional political organization and ethnic identity formation, and evaluate how macro-scale processes affect micro-scale phenomena. Specifically, we argue that architecture reflects different community patterns of ritual, integration, and inequality. As a case study, we employ a diachronic perspective for two periods in Peruvian south coastal prehistory to assess the magnitude of changes implied by the genesis of Nasca society out of the preceding Paracas. Survey and excavation data from residential sites in the southern Nasca region indicate that important modifications in local community organization accompanied the regional, wide-ranging effects of Nasca society and its innovative form of regional integration. Comparison of the residential built environment from both periods suggests important changes in ritual and patterns of status acquisition and maintenance. In addition, house form indicates that a greater level of household autonomy accompanied increasing regional integration and a decrease in conflict. 相似文献

This ethno-geoarchaeological study considers the formation of archaeological deposits through a study of abandoned contemporary mudbrick structures on the Taraco Peninsula, Bolivia. The study site was a domestic compound with rooms for different functions that had been abandoned for over 50 years. Structures were in variable states of decay in terms of roof cover, walling integrity and abandonment fills. Geoarchaeological samples were collected from intact and weathered adobes, earthen hearths, mud plaster, and flooring. Adobes and mud plaster were locally derived from topsoil containing archaeological sediments with added gravel and plant temper. This study found a relatively light anthropogenic signature for decayed earthen houses.Rising damp exfoliated mud plaster despite un-mortared cobble wall foundations. Organic matter from roof fall attracted thriving soil faunal populations, which furthered site destruction through bioturbation, particularly packed earth floors. Sediments derived from weathered mudbrick retained little evidence of prior use as construction materials unless exposed to heat. Sediments exposed to high-temperatures produced the most distinctive rubified features but were structurally compromised. Isolated thermal features from decomposed adobe would not be distinguishable from other hearth types. Adobes exposed to low or moderate heat had few distinctive features in thin section. Intact adobes and floors that were not exposed to heat have fewer pores than natural sediments and distinctive grass inclusions. These adobes disarticulated into loose sediments when exposed to weathering. Adobe fall outside the crumbling structures blended into topsoil.This study sheds light on functional attributes of pre-Columbian construction practices. Thick, fine-textured sterile flooring is commonly encountered in the study region. This would control bioturbation from roof fall in a previous occupation enabling reconstruction in abandoned dwellings. In contrast to the contemporary dwelling, prehistoric mortared cobble foundations would resist rising damp. Cobbles without mortar may relate more to design and construction than durability. These contrasts between contemporary and prehistory construction practices reflect differences in the design, construction costs and functional use-life of adobe structures. 相似文献

Tirana, the Balkan capital examined in this study, displays patterns of gendered job search behavior and access, which are unique within contemporary Europe and even within post-socialist Central and Eastern Europe. Here, it is a rather spatially constricted job search range rather than transport poverty that prevents women living in first-ring suburbs from attaining satisfactory employment. Female commutes are extraordinarily short and most often on foot. While the city now has nearly one million inhabitants and a high car ownership rate, and is located in Europe, the employment and mobility choices and behaviors of its female residents resemble those in developing rather than developed countries, and in small rather than large cities. The reasons underpinning this situation have more to do with socio-cultural gender barriers and less with transport poverty or labor market weaknesses. This finding might apply to other Balkan capitals or cities outside Europe, which have recently experienced large waves of internal migration and where both existing residents and newcomers have not yet adjusted to ‘big city’ life. 相似文献

中原北方宋辽金时期涅槃图像考察 总被引:1,自引:0,他引:1

中原北方宋辽金时期涅槃图像,具有时代共通性的一面,同时呈现东部地区与西部地区的地域差异。在图像表现方面,两地区涅槃图像不同程度地继承了唐代因素,相对来说,东部地区沿用的唐代因素较多;西部地区在唐代基础上又部分地吸收了东部地区宋代因素,并获得新发展。在图像内涵方面,东部地区表现为涅槃与弥勒佛组合,延续了传统图像的做法,着意表述佛法传承的意图。涅檗与三身佛组合是这一时期的新现象,反映了大乘佛教权道、化现思想。西部地区表现为涅槃、罗汉、横三世佛(释迦·弥勒·阿弥陀)组合,一方面强调了罗汉守护和传承佛法的作用,另一方面凸显信徒向往并期望将来往生净土世界的心态。东西两地区有关摩耶夫人画面的流行,与当时社会大力倡导孝行的情况密切关联。涅槃升仙图像则是佛教进一步世俗化的表现。 相似文献
