According to the national Demographic and Health Surveys (DHS), between 10% and 90% of women in poorer countries agree that domestic violence against women is justified. Such wide variation in women’s responses raises concerns about the comparability of the underlying attitudinal question, and the validity of comparative research that assumes comparability. Using 67 DHS conducted in 48 countrie...
Premarital fertility, defined as birth before first marriage, is investigated in Madagascar, using two Demographic and Health Surveys (DHS) conducted in 1992 and 1997. About 8 per cent of all births and 23 per cent of first births take place before marriage, despite a low underlying mean age at first marriage, estimated to be 18.6 years in the absence of a previous birth. A premarital first bir...
Surveys conducted in the context of the Demographic and Health Surveys (DHS) programme are an important source of data on health of families in developing countries. Both at the national and international level, DHS surveys provide much-needed data on fertility and family planning, on mortality and nutrition, and on health services utilization. The use of uniform survey instruments allows detai...
Turkey has been experiencing significant fertility decline since the 1950s. Increasing mean ages at childbearing have accompanied this decline, thus studies regarding tempo effects are necessary for Turkey. The main aim of this study is to reveal the tempo distortions in recent period fertility in Turkey as a whole and for different sub-groups by using an adjustment procedure. A procedure by Bo...
In Nigeria, decades of protracted military rule deepened poverty and created a situation in which many children are undernourished.

Today Nigeria is among the ten countries in the world with the largest number of underweight children, with an estimated...
Evolutionary toxicology is a young field that has grown rapidly in the past two decades. The potential of this field comes from the ability to link chemical contamination to multigenerational and population-wide effects in various species. The advancements and rapidly decreasing costs of -omic tools are improving the power and resolution of evolutionary toxicology studies. In this manuscript, w...
The field of predictive toxicology requires the development of open, public, computable, standardized toxicology vocabularies and ontologies to support the applications required by in silico, in vitro, and in vivo toxicology methods and related analysis and reporting activities. In this article we review ontology developments based on a set of perspectives showing how ontologies are being used ...
