THEORETICAL BASIS OF STUDYING MIGRATION AND MIGRATION PROCESSES

The Internal Dynamics of Migration Processes: A Theoretical Inquiry

The migration literature has identified various feedback mechanisms which explain why, once started, migration processes tend to become partly self‐perpetuating, leading to the formation of migrant networks and migration systems. However, existing theories on the internal dynamics of migration processes are characterised by three fundamental weaknesses. First, their focus on migrant networks co...

Migration processes

Neighboring group’s effect in sigmatropic migration on indol rings. A theoretical study and NBO analysis

Structural properties, energies behavior and NBO analysis was performed for1-5 prototrophic shift endinelboran where substitutions like H, CH3 and CF3 that were placed on Benzene were investigated by usingDFT-B3LYP/6-311+G** level of theory. The Results show that, -BH2 shift doesn’t take place and a kind of[1,3] shift for borotrophic occured. In prototrophic shift, however, [1,5] transition eas...

Elderly Migration and Its Correlates in Iran

Objectives: When it comes to migration, the migration of young people comes to mind and the migration of the older adults is ignored. While, migration after retirement is an important and increasing phenomenon. The reasons and destinations of migration of the older persons are different from those of the young. Young people usually migrate to urban destinations and further distances with more ...

Data migration: A theoretical perspective

Article history: Accepted 25 September 2012 Available online 23 December 2012 In this paper we investigate data migration fundamentals from a theoretical perspective. Following the framework of abstract interpretation, we first discuss models and schemata at different levels of abstraction to establish a Galois connection between abstract and concrete models. A legacy kernel is discovered at a ...
