A bivariate competing risks problem is considered for a rather general class of survival models. The lifetime distribution of each component is indexed by a frailty parameter. Under the assumption of conditional independence of components the correlated frailty model is considered. The explicit...

In the second part of these reflections, we use the connection between marriage and first childbearing to demonstrate further issues involved in anticipatory analysis. We show that an anticipatory approach cannot be used to represent intentionality: People may marry with the intention of having...

This paper is the latest in a series initiated in 1999 which investigates childbearing in low fertility countries from a cohort perspective. Principal conclusions: Major changes in childbearing patterns are continuously taking place in almost all countries. Large families with four and more...

Our research objective was to systematise the existing literature on the relation between fertility and women’s employment at the micro-level. Instead of carrying out a traditional literature review, we conducted a meta-analysis. This allowed us to compare estimates from different studies...

Objectives - We examine the relationship between sleep duration and health in the high mortality context of Russia. Methods - Night and daytime sleep durations are based on self-reports and 24-hour heart rate trends (Holter monitoring). The sample of 201 individuals (Holter data for 185) is...

Inverse problems play important role in science and engineering. Estimation of boundary conditions on the temperature distribution inside a metallurgical furnace, reconstruction of tissue density inside body on plane projections obtained with x-rays are examples. The similar problems exist in...

Procedures that seek to explain current behavior by future outcomes (anticipatory analysis) constitute a widespread but problematic approach in life-course analysis because they disturb the role of time and the temporal order of events. Nevertheless the practice is often used, not least because...

Background: Epigenetic inheritance is a potentially important determinant of health in several mammals. For humans, the existing evidence is weak. We investigate whether disease exposure triggers functional epigenetic inheritance among humans by analyzing siblings who were conceived under...
