Polarization and optimal allocation of migrants
This is a collection of scientific papers on migration studies.
The interaction of short single-component vector solitons in the frame of the coupled third–order nonlinear Schrodinger equations taking into account third–order linear dispersion, self–stepping, self–stimulated Ramanscattering, cross–stepping and cross–stimulated Raman-scattering terms is considered. Conditions of reflection and propagation of the solitons through each other and also the condition of oscillator interaction (vector breather) are obtained.
The subject matter of the article is the EU immigration policy applied to third country nationals (TCN). The main aspects of the policy are considered: humanitarian policy, national security policy, and various legal tools of its implementation. In particular the author considers the 1951 Geneva Convention and 1967 New York Protocol relating to the status of refugees, the clauses of the Treaty on the Functioning of the EU regulating «area of freedom, security and justice» (title V), Schengen Conventions, the related acts of the EU secondary law. As to the humanitarian aspect of the EU immigration policy, its moral essence - the respect for human dignity is emphasized. The national security measures are directed mainly against illegal immigration. Finally the author comes to the conclusion that EU humanitarian efforts in the immigration policy proved to be more effective than the security one.
The chapter analyzes the specifics of the migration of population exchange Russia and former Soviet countries for the 1990-2000's.
The twenty-seven volume of the series "International Migration of Population: Russia and Contemporary World" is a collection of papers submitted to the Session 06-03 "The effects of migration on areas of destination" of the XXVII IUSSP International Population Conference *26031 August 2013, South Korea, Busan). The session deals with major international migration trends, increasing role of international migration in the demographic development of receiving countries.
The authors are responsible for the reliability of data and other materials used. The series is both of scientific and educational character and can be accordingly used in teaching process.
In the article authors use the vital birh and death registration data on 10 regions exctracted from the Rosstat database to evaluate an input of international migrant into Russian fertility and mortality levels.
In the frame of the third-order nonlinear wave dispersion theory the equation of motion of a vector wave packets mass center taken in to account arbitrary inhomogeneity profile is obtained. As short vector wave packets localized motion as infinite motion is shown. Short vector wave packets localizations area can be as bigger as smaller in comparison with long vector wave packets localizations area. The effect depend from third-order linear dispersion parameter.
