STRUCTURE AND FUNCTION OF THE NEMATOSOME

The ultrastructural morphology of human placental and mouse placental nematosomes has been investigated. The description includes a three-dimensional analysis of the shape of the organelles based on serial sectioning, measurements of the repeat distance of the subunit fibre of the organelle derived by optical diffraction analysis and the results of an ultrastructural cytochemical study designed to test whether the organelle contains nucleic acid

Contexts of exit in the migration of Russian speakers from the Baltic countries to Ireland

Recently, Ireland has become a major destination for migrants from Estonia, Latvia, and Lithuania. Many of these migrants are members of Russian-speaking minorities leaving a context of restrictive citizenship and language laws and varying degrees of ethnic tension. This paper draws on interviews collected in Ireland to examine the role played by the contexts of exit in decisions to migrate among Russian-speaking minorities from the Baltics. The results suggest that Russian speakers from Estonia migrate because of their experiences as minorities, while those from Latvia and Lithuania migrate to escape low wages and irregular employment. This is so despite equally restrictive language and citizenship laws in Estonia and Latvia. I argue that the effect of state policy as a push factor for minority emigration is mediated by other contextual aspects, such as levels of contact, timbre of ethnic relations, and the degree of intersection between economic stratification and ethnicity
