German reunification provides a unique quasi-natural experiment to study the integration of two economies with perfect factor mobility. The reallocation of capital and labor is the most striking characteristic of German unification and may affect the macroeconomic development in East and West Germany in the long run. Therefore, a baseline two-region open economy model is set up to study the int...

Cultures of brucella-sensitized mouse spleen cells exposed to Brucella abortus antigens in vitro release macrophage migration inhibition factor (MIF) and macrophage spreading factor. Subjecting the supernatants from such cultures to preparative scale electrophoresis in acrylamide gel yields several fractions, one of which contains both MIF and macrophage spreading factor. This material has prop...

Migrant housing and mobility patterns are affected by both the unique institutional factors related to migration and a common set of socio-economic characteristics shared by urban residents. China’s unprecedented waves of internal migration are accompanied by long-standing rural–urban and local–nonlocal divides that have been institutionalized through the household registration system. This pap...

Realistic mobility models can demonstrate more precise evaluation results because their parameters are closer to the reality. In this paper a realistic Fuzzy Mobility Model has been proposed. This model has rules which are changeable depending on nodes and environmental conditions. It seems that this model is more complete than other mobility models.After simulation, it was found out that not o...
