The impact of union formation dynamics on first births in West Germany and Italy: are there signs of convergence?
In this paper we investigate the changing impact of union formation on the transition to parenthood in West Germany and Italy using FFS data. We first draw attention to overall cohort patterns in union formation and first births and then describe the mutual relationships between union formation, first marriage, and first births. On the basis of event-history models, we then evaluate the impact of union formation behaviour on the transition to motherhood. In particular, we test whether the impact of union status has been changing for younger and older cohorts, thereby investigating whether the heterogeneous spread of non-marital childbearing is gaining relevance as we would expect from the perspective of the Second Demographic Transition. The findings from these analyses allow us to conclude that demographic behaviour is not converging from a cohort perspective. (AUTHORS)Germany/FRG, Italy

Phase-matched coherent hard x-rays from relativistic high-order harmonic generation
High-order harmonic generation (HHG) with relativistically strong laser
pulses is considered employing electron ionization-recollisions from multiply
charged ions in counterpropagating, linearly polarized attosecond pulse trains.
The propagation of the harmonics through the medium and the scaling of HHG into
the multi-kilo-electronvolt regime are investigated. We show that the phase
mismatch caused by the free electron background can be compensated by an
additional phase of the emitted harmonics specific to the considered setup
which depends on the delay time between the pulse trains. This renders feasible
the phase-matched emission of harmonics with photon energies of several tens of
kilo-electronvolt from an underdense plasma
