In this paper we show the results of a study concerning 42 axes, mainly discovered in the Copper Age pile dwellings of Ljubljansko barje (central Slovenia) and in the neighbouring areas of Caput Adriae. The studied shaft‐hole axes, characterized by homogeneous typology but slightly different raw materials, have been called ‘Ljubljana‐type’ axes (Lt). The raw materials show a common OIB‐like signature and metamorphic and spilitization features that recall oceanic conditions. The typological and geochemical characteristics and the very high percentage of Lt axes among the polished stone axe assemblages of Ljubljansko barje suggest that the raw material was probably gathered from one or more relatively small outcrops close to Ljubljansko barje. Similar igneous rock types outcrop in the presumably Palaeozoic diabase/shale complex (Eisenkappler Diabaszug), intruded by the northern Karawanken plutonic belt. A probable provenance from this area, particularly rich in copper ore deposit, would confirm the important role of Ljubljansko barje as a metallurgical district, as well as a strong relation between lithic raw materials and Cu cultivation districts during the Copper age. 相似文献
Is North Korea ready and willing to give up its nuclear weapons? Proponents of arms control and sustained engagement with North Korea maintain that Pyongyang's desire to acquire nuclear weapons stemmed from ingrained insecurity vis-à-vis the United States or more specifically, the threat that the US poses to fundamental regime security.
However, the primordial source of Kim Jong Il's existential insecurity stems largely from the abnormal, structural idiosyncracies of his regime and not, as many naively believe, the hardline policies of the Bush administration. Accordingly, the Kim Jong Il regime's fundamental dilemma boils down to the fact that the domestic political costs of giving up its nuclear capabilities are just as high as the costs of retaining them.
Debunking the myth that the US, rather than North Korea, poses the greater challenge to South Korean security is as important as ensuring that North Korea dismantles its nuclear arsenal. 相似文献
Economic growth in China in recent decades has largely rested on the dynamism of its cities. High economic growth has coincided with measures aimed at improving the efficiency of local governments and with a mounting political drive to curb corruption. Yet the connection between government institutions and urban growth in China remains poorly understood. This paper is the first to look into the link between government efficiency and corruption, on the one hand, and urban growth in China, on the other hand and to assess what is the role of institutions relative to more traditional factors for economic growth in Chinese cities. Using panel data for 283 cities over the period between 2003 and 2014, the results show that the urban growth in China is a consequence of a combination of favorable human capital, innovation, density, local conditions, foreign direct investment, and city‐level government institutions. Both government quality—especially for those cities with the best governments—and the fight against corruption at the city level have a direct effect on urban growth. Measures to tackle corruption at the provincial level matter in a more indirect way, by raising or lowering the returns of other growth‐inducing factors. 相似文献
