BACKGROUND Public health researchers are increasingly encouraged to establish international collaborations and to undertake cross-national comparative studies. To-date relatively few such studies have addressed migration, ethnicity and health, but their number is growing. While it is clear that divergent approaches to such comparative research are emerging, public health researchers have not so...

Discordance between mitochondrial and nuclear DNA has been noted in many systems. Asymmetric introgression of mitochondria is a common cause of such discordances, although in most cases the drivers of introgression are unknown. In the yellow-rumped warbler, evidence suggests that mtDNA from the eastern, myrtle warbler, has introgressed across much of the range of the western form, the Audubon's...

This article presents a unique framework for analyzing the politics of immigration control in developed countries and reviews related political theories. The author describes distinctive patterns of immigration in selected OECD countries and standard explanations. The author argues that the costs and benefits of immigration are spatially unevenly distributed and explains how spatial concentra...

Do economic considerations shape attitudes toward immigration? In this article, we consider the relationship between economic interests and immigration preferences by examining how developments in individuals’ sectors of employment affect these views. Using survey data across European countries from 2002 to 2009 and employing new measures of industry-level exposure to immigration, we find that ...

BACKGROUND Knowledge of immigration and emigration rates is crucial for understanding of population dynamics, yet little is known about these vital rates, especially for arctic songbirds. We estimated immigration in an Arctic population of northern wheatears on Baffin Island, Canada, by the use of stable hydrogen isotopes in tail feathers (δ(2)HK). We assumed that δ(2)HK values of juvenile (hat...

Immigration and Labor Productivity: New Empirical Evidence for Spain The purpose of this paper of this paper is to explore the immigration and productivity in Spain. We estimate the effect of immigration on labor productivity from 2004 until 2008 for Spain. Using firms (SABI) and individuals data (Social Security Records) we calculate the effect by sector and municipality for the two big Spanis...

Public discourse concerning immigration and immigration policy often relies on the characterization and universalization of the threats that are posed by increasing immigration. It is the specification and reference to these threats that allows one to consider immigration as ―moral panic.‖ It is through this lens, that I undertake a content analysis of letters to the editor that appeared in a l...

We investigate the effect of immigration on the labor supply of skilled women, using data on Spain’s large recent immigration wave. We adopt a spatial correlations approach and instrument for current immigration using ethnic networks. We find that female immigration increases the local availability of household services and reduces their price. It also increases the labor supply of skilled nati...

Australian immigration detention centres are in secluded locations, some on offshore islands, and are subject to extreme secrecy, comparable with 'black sites' elsewhere. There are parallels between healthcare professionals working in immigration detention centres and healthcare professionals involved with or complicit in torture. In both cases, healthcare professionals are conflicted between a...
