Children seem to present a barrier to the gender revolution in that parents are more likely to divide paid and domestic work along traditional gender lines than childless couples are. However, the extent to which this is so varies between countries and over time. We used data on 35 countries from the 2012 International Social Survey Programme to identify the contexts in which parents and non-parents differ the most in their division of labour. In Central/South America, Eastern Europe, Southern Europe, Asia, and South Africa, labour sharing configurations did not vary as much with the presence of children as in Australia, Western Europe, North America, and Northern Europe. Our multilevel models helped explain this pattern by showing that children seem to present a greater barrier to the gender revolution in richer and, surprisingly, more gender equal countries. However, the relationship between children and couples' division of labour can be thought of as curvilinear, first increasing as societies progress, but then weakening if societies respond with policies that promote men's involvement at home. In particular, having a portion of parental leave reserved for fathers reduces the extent to which children are associated with traditional labour sharing in the domestic sphere.

Efforts to improve child survival in lower-income countries typically focus on fundamental factors such as economic resources and infrastructure provision, even though research from post-industrial countries confirms that family instability has important health consequences. We tested the association between maternal union instability and children's mortality risk in Africa, Latin America and the Caribbean, and Asia using children's actual experience of mortality (discrete-time probit hazard models) as well as their experience of untreated morbidity (probit regression). Children of divorced/separated mothers experience compromised survival chances, but children of mothers who have never been in a union generally do not. Among children of partnered women, those whose mothers have experienced prior union transitions have a higher mortality risk. Targeting children of mothers who have experienced union instability-regardless of current union status-may augment ongoing efforts to reduce childhood mortality, especially in Africa and Latin America where union transitions are common.

Tras el Concilio Vaticano II, un amplio sector de la doctrina canónica ha prestado particular atención al tema de la sacramentalidad del matrimonio y a su relevancia jurídica. Diversos factores parecen haber movido a los autores a reflexionar sobre este aspecto. Por una parte, el proceso de secularización de la sociedad, ha llevado a la difusión de una visión terrena del matrimonio, negando su carácter sobrenatural (sacramental), y a una progresiva desvinculación de esta realidad respecto de
