During recent reinvestigations in the Great Cave of Niah in Borneo, the ‘Hell Trench’ sedimentary sequence seen by earlier excavators was re-exposed. Early excavations here yielded the earliest anatomically-modern human remains in island Southeast Asia. Calibrated radiocarbon dates, pollen, algal microfossils, palynofacies, granulometry and geochemistry of the ‘Hell Trench’ sequence provide information about environmental and vegetational changes, elements of geomorphic history and information about human activity. The ‘Hell’ sediments were laid down episodically in an ephemeral stream or pool. The pollen suggests cyclically changing vegetation with forest habitats alternating with more open environments; indicating that phases with both temperatures and precipitation reduced compared with the present. These events can be correlated with global climate change sequences to produce a provisional dating framework. During some forest phases, high counts of Justicia, a plant which today colonises recently burnt forest areas, point to fire in the landscape. This may be evidence for biomass burning by humans, presumably to maintain forest-edge habitats. There is evidence from palynofacies for fire on the cave floor in the ‘Hell’ area. Since the area sampled is beyond the limit of plant growth, this is evidence for human activity. The first such evidence is during an episode with significant grassland indicators, suggesting that people may have reached the site during a climatic phase characterised by relatively open habitats ∼50 ka. Thereafter, people were able to maintain a relatively consistent presence at Niah. The human use of the ‘Hell’ area seems to have intensified through time, probably because changes in the local hydrological regime made the area dryer and more suitable for human use. 相似文献

In Turkey, poverty has been a main subject of debates since 1960s. It used to be a serious problem for both rural areas and the big cities that gained migration. In Turkey and world-wide since the 1980s, however, there have been more research interests in the concentrated urban poverty, especially along with the increase in levels of impoverishment around the world. With the help of a case study in Izmir (Turkey), this paper aims to examine the process of concentrated urban poverty from different points of view in the literature. This is a case study developed at the peripheries of the traditional city centre—or inner areas—of the city of Izmir, Turkey. The paper, first, discusses the parameters of concentrated poverty according to the literature. Then it introduces the study findings of the author, which point out the macro-scale, micro-scale and ecological dynamics that are important in the development of concentrated urban poverty. The macro-scale dynamics suggest that poverty in inner areas of the city are related to the unbalanced development trends within the country, such as the overgrowth of metropolitan cities, economic restructuring processes, migration trends and the development of informal economy. The ecological dynamics address to the housing and job location preferences and invasion-succession processes in the city, which emphasize that socio-economic characteristics of inner areas of the city are different from those of other city parts. Micro-scale dynamics are related to poors' ability of developing solidarity relations among themselves, which is also related to the spatial characteristics of inner areas of the city, according to this study's findings. 相似文献

In Guatemala local perspectives on heritage often remain unheard. In this paper a case study is presented to show the complex relationship between the highland site of Iximche’ and Tecpán, an Indigenous community nearby. Although Iximche’ is of little importance to the local economy, its significance is derived from its role as a field for different kinds of social and religious interactions. Traces of a spiritual relationship to this place can be dated back to the colonial period and today Maya from all over Guatemala go there to perform ceremonies. The place has also become a focal point of identity constructions for locals, Pan Mayan activists and the nation itself. The ruins of Iximche’ play an important role in the construction of collective memory which also includes ideas coming from external players such as Christian churches, the national government, Mayan activists, and archaeologists as well. 相似文献
