The phrase "a model of migration" is correct and usable in written English.
It can be used when discussing a theoretical framework or representation that explains or illustrates the process of migration.
Example: "The researchers developed a model of migration to better understand the factors influencing population movement across borders."
Alternatives: "a framework for migration" or "a representation of migration".
In the first part of their empirical analysis, they estimate a model of migration with household resources (non-durable consumption) and networks (migration prevalence) as determinants.
Following McKenzie and Rapoport (2007), we use a model of migration decision, which includes a measure of households' wealth level in polynomial form (degree 2), interacted with a measure of the local migration prevalence, capturing network effects facilitating migration.5 In addition, we will consider labor market outcomes and their interaction with wealth, as determinants of migration.
Taken together, our data support a model of DC migration where chemotactic factors trigger cell polarisation and initiation of podosomes to sustain the leading edge for migration.
Next, we will develop and discuss a model of temporary migration.
This study was designed to develop a model of the migration experience beginning before migrants leave their country of origin and continuing through the acculturation process.
We therefore sought to measure the effect of Ir-LBP on the diapedesis aspect of this process by using a model of transendothelial migration described in 1997 by Nohgawa and co-workers [39].
Numerous genetic studies have been conducted to determine the mechanisms underlying influenza A virus seasonality among humans; most results support a model of global migration (6 – 11 ).
Distances from Africa were derived from a previous work (Handley et al. 2007) and refer to a model of human migration from East Africa along landmasses and avoiding mountain regions with altitude over 2,000 m.
Consistent with a model of neuronal migration defect as the cause of molecular layer heterotopia (MLH), Bergmann glia in heterotopia exhibit morphological abnormalities with radial fibers that fail to reach the pial surface [ 11] or with fibers that inappropriately cross into the adjacent molecular layer [ 13].
This type of distribution is expected from a founder event matching a leptokurtic model of migration (with a greater number of long distance migrants) where the populations behind the initial migration front do not advance as readily [ 15, 67].
We extended the algorithm from Birkner and Blath (Birkner and Blath 2008) – which generates samples under a beta-coalescent at equilibrium – to include an island model of migration (each lineage migrates to another population at rate M) and an isolation period.
