The Role of Cultural Clustering in Attracting New Immigrants 总被引:2,自引:0,他引:2
Abstract This paper argues that new immigrants cluster in culturally homogeneous groups in the host country because of imperfect information. However, a pulling effect exists provided that the cultural communities are not too large. With a panel of migration flows to the major O.E.C.D. countries from the mid 1980s to the mid 1990s, it is shown that the existence of similar cultural communities attracts new immigrants. However, the effect is not homogeneous for all types of source and destination countries. Furthermore, the pulling effect is shown to fall to zero for cultural communities above a certain threshold size. 相似文献

Tools are developed to predict damage to archaeological remains caused by the construction of line infrastructure on soft soil. They are based on numerical modelling and laboratory testing supported by X-ray microcomputed tomographic observations, and micromorphological analyses of thin sections. They have been validated for one-dimensional (1D) loading at two sites in the Netherlands where soil has been placed on top of organic layers rich in ecofacts and overlaying Pleistocene sands.Numerical prediction of the deformation of soft layers underneath an embankment remains a challenge for geo-technical engineers. Errors on surface settlement prediction reach ±15% of the measured total settlement.Laboratory observations show that vulnerable artefacts can get crushed when packed loosely in pure assemblies under 1D loading equivalent to less than 5 m of sand. Fragmentation is assimilated to loss of archaeological value as it compromises recovery during sieving. Embedment in a sandy or a very compressible organic matrix has a beneficial effect on the resistance of ecofacts. Embedded ecofacts can resist a load of more than 12 m of sand. Flattening and re-orientation of soft plant remains occur during 1D loading without microscopic damage of tissues. 相似文献

Unlike L'Illustration, with which it competed under the Second Empire, the weekly Le Monde illustré, which first appeared in 1857 and which was protected by the imperial government, did not count among the political newspapers overtaxed under Napoléon the Third's repressive regime. For this reason, it made great strides thanks to its blind allegiance to a French imperialism that had asserted its authority during the Crimean war, but which spent itself during the war against Juárez and his republican partisans in Mexico. While the French liberal press criticized the Second Empire foreign policy, Le Monde illustré persisted in turning the Mexican war into an antijuarist pacification favorable to a new Latin colonial empire, as well as to an application of the Saint-Simonian doctrine on Mexican industry and economy. In order to achieve this, the illustrated reports on the expeditionary force, military operations, and French victories were a warmongering that aimed to place this campaign in the afterglow of the conquistadors' era, as well as to idealize the imperial army as a symbol of the French nation. 相似文献
