Walled sites attributed to the Xiongnu steppe empire (2nd century b.c.–1st century a.d.) constitute the earliest investments in explicitly non-mortuary built environments among pastoralists of the Mongolian Steppe. These permanent constructions are important precedents to the medieval towns of subsequent steppe empires, yet very little of the complete layouts and surrounding remains of the large enclosures are understood. Our investigations of the walled site at Kherlen-Bars in eastern Mongolia are among the first surveys to fully document all aspects above and below ground across an entire Iron Age walled site area. In addition to detailed documentation of the large structures, our geomagnetic prospections and digital elevation modeling brought to light numerous small sub-surface and subtle-surface features that show such early walled sites, often deemed virtually empty, to be far more complex and diachronic in their formation processes and possible functions. 相似文献

Comparing degrees of religiosity, Canada and the US have been moving along divergent trajectories for the past several decades. Regional variations are evident in both societies, but, taken as a whole, the divergence holds up even when these intrasocietal differences are accounted for. Neither the classic secularization thesis nor the more popular religious economy model in the sociology of religion adequately explain the contemporary disparities in religious practice and belief in the two societies. More compelling explanations lie in human security and welfare state models. Canadian and US demographic patterns, particularly internal differences among recent immigrants, are additional explanatory factors. Levels of existential security and immigration trends in the two societies are likely to sustain the divergence in religiosity. 相似文献

The expansion of primary breeding companies for layer hens has reached a global scale. Two groups of companies, the Dutch Hendrix Genetics BV and the German EW Group GmbH, dominate the trade with layer hens for industrial egg production in most countries of the world. This article aims to identify the main actors of industrial egg production and to analyse the structure of the global layer hen production network. Furthermore, this paper examines the importance of brands and quality within the production network. While the primary breeding level is discussed on a global scale, the secondary breeding level and the egg production is analysed at a national level for Germany. Since the importance of brands is strongly related to the quality of the products and the trust therein, the structure of the layer hen production network in regard to the role of brands and trust is evaluated. For this evaluation, the authors combined the global production network approach with elements of the convention theory. 相似文献

The eastern Mediterranean, with its long archaeological and historical records, provides a unique opportunity to study human responses to climate variability. We review paleoclimate data and reconstructions from the region with a focus on the last 6000 years. We aim to provide an up-to-date source of information on climate variability and to outline present limitations and future opportunities. The review work is threefold: (1) literature review, (2) spatial and temporal analysis of proxy records, and (3) statistical estimation of uncertainties in present paleoclimate reconstructions (temperature, °C). On a regional scale the review reveals a wetter situation from 6000 to 5400 yrs BP (note: all ages in this paper are in calibrated years before present (i.e. before 1950), abbreviated yrs BP, unless otherwise stated). This is followed by a less wet period leading up to one of fully-developed aridity from c. 4600 yrs BP. There is a need for more high-resolution paleoclimate records, in order to (i) better understand regional patterns and trends versus local climate variability and to (ii) fill the gap of data from some regions, such as the Near East, Greece and Egypt. Further, we evaluate the regional occurrence of a proposed widespread climate event at 4200 yrs BP. This proposed climate anomaly has been used to explain profound changes in human societies at different locations in the region around this time. We suggest that although aridity was widespread around 4200 yrs BP in the eastern Mediterranean region, there is not enough evidence to support the notion of a climate event with rapidly drying conditions in this region. 相似文献
