Family-policy regimes unfavourable to combining employment with motherhood have been claimed to increase socio-economic differentials in fertility as combining employment and motherhood has become more normative. This claim has to date been explored mainly in reference to 'liberal' AngloAmerican regimes. Comparing education differentials in age at first birth among native-born women of 1950s and 1960s birth cohorts in seven countries representing three regime types, we find persistence in early first births among low-educated women not only in Britain and the United States but also in Greece, Italy, and Spain. Shifts towards later first births, however, were more extreme in Southern Europe and involved to some extent women at all education levels. The educationallyheterogeneous changes in age patterns of first births seen in the Southern European and AngloAmerican family-policy regimes contrast with educationally-homogeneous changes across birth cohorts seen in the study's two 'universalistic' countries, Norway and France.
Se analizan, desde el punto de vista sedimentológico, unos materiales correspondientes a las facies Keuper entre la Cordillera Ibérica y el Sistema Central. Dos aspectos resaltan tras este análisis: -Desplazamiento de la línea de costa (que durante la sedimentación del Rot y del Muschelkalk estaba situada en esta zona) hacia el Este. -Marcado cambio lateral de facies desde el Oeste hacia el Este, pasando de unas facies proximales-medias de abanico aluvial a unas facies distales y ambiente de sabkha continental. ABSTRACf This paper deals witb the sedimentological analysis of tbe materials tbat correspond to tbe Keuper facies in the area situated between tbe Iberian Ranges and tbe Central System. Acording to the obtained data, two main aspects are empbasized: -During the Upper Triassic, a c1ear retreat of tbe roast line towards the East took place, since tbis area constituted tbe litoral zone during tbe sedimentation of tbe Rot and Muschelkalk. -Facies change lateraly from West to East as proximal alluvial Can sediments pass into facies interpreted as distal alluvial fans and continental sabkha environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
