This is because widening health inequalities may be the result of selective migration processes whereby healthy individuals migrate to healthy areas and away from areas of relatively higher deprivation and poorer health [ 19, 20].
Rather, evidence of health selective migration was found whereby individuals of poorer health migrated to areas that displayed poorer health and social characteristics (and vice versa).
The first option is related to selective migration.
This suggests that composition bias due to selective migration is not likely to be a problem for this analysis.
We find that the area suffers from population decline and an ageing population due to selective migration processes.
This natural experiment design solves the major problem of extant approaches to the theory, i.e., the selective migration of minorities to areas with high concentrations of jobs.
This study developed a bioactive knitted silk-collagen sponge scaffold by incorporation of exogenous SDF-1 alpha, to enable selective migration and homing of cells for in situ tendon regeneration.
Some countries do exhibit changes in literacy along cohort lines that cannot be easily attributed to selective migration or mortality and may indicate 'true" gains or losses in individual literacy.
In the case of skill mismatch, instead, the policy options are more complex and may range from selective migration for immigrants whose characteristics are more compatible with the host country's needs to labor market policies aimed at educating and training workers to help them become more suited to local labor market requirements.
This should promote selective migration of CII-specific Th2 cells to the diseased tissue where they can exert their effect.
Increased proportion of Treg cells in melanoma tumors than in peripheral blood and peritumoral tissue was also reported in melanoma patients and was attributed to selective migration and/or expansion of Treg cells in tumors [42].
