This study investigates the effects of the macroeconomic context on attitudes to immigration. Earlier studies do in some cases not provide significant empirical support for the existence of important such effects. In this article it is argued that this lack of consistent evidence is mainly due to the cross-national setup of these studies being vulnerable to estimation bias caused by country-spe...

BACKGROUND Immigrant studies offer insights into the relative importance of environment and genes in disease etiology. There is considerable variation in testicular cancer incidence worldwide. We investigated testicular cancer risk in first- and second-generation immigrants to Denmark, a high-incidence country, to evaluate the relative influence of genes and environment and the potential timing...

Special relativity is most naturally formulated as a theory of spacetime geometry, but within the spacetime framework probability appears to be a purely epistemic notion. It is possible that progress can be made with rather di¤erent approaches covariant stochastic equations, in particular but the results to date are not encouraging. However, it seems a non-epistemic notion of probability can be...

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...

Education usually shows a relationship with self-rated health such that those with highest education have the best health and those with lowest education have the worst health. We examine these educational gradients among Asian immigrants and whether they differ by country of origin, duration in the United States, and generational status. Migration theories suggest that recent immigrants from p...

We consider a mathematical model for the group size determination by the intra-reactions, self-growth, ostracism and fission within a group, and by the inter-reactions, immigration and fusion between two groups. In some group reactions, a conflict between two groups occurs about the reaction to change the group size. We construct a mathematical model to consider such conflict, taking into accou...

Abstract The European Union (EU) faces challenges that affect its persistence, including the revival of national populism in many EU member states. Studies have shown individuals with immigration histories identify less strongly Europe than without histories. Therefore, fostering a strong identification is more relevant ever. This paper will explore possible historical roots different levels an...

Citizenship tests are designed to ensure that new citizens have the knowledge required for successful 'integration'. This article explores what those who have taken the test thought about its content. It argues that new citizens had high levels of awareness of debates about immigration and anti-immigration sentiment. Considering new citizens' views of the test, the article shows how many of the...

Migration is an important event in the life history of many animals, but there is considerable variation within populations in the timing and final destination. Such differential migration at the population level can be strongly determined by individuals showing different consistencies in migratory traits. By tagging individual cyprinid fish with uniquely coded electronic tags, and recording th...
