Gender, turning points, and boomerangs: returning home in young adulthood in Great Britain

The idea of a generation of young adults “boomeranging” back to the parental home has gained widespread currency in the British popular press. However, there is little empirical research identifying either increasing rates of returning home or the factors associated with this trend. This article addresses this gap in the literature using data from a long-running household panel survey to examine the occurrence and determinants of returning to the parental home. We take advantage of the longitudinal design of the British Household Panel Survey (1991–2008) and situate returning home in the context of other life-course transitions. We demonstrate how turning points in an individual’s life course—such as leaving full-time education, unemployment, or partnership dissolution—are key determinants of returning home. An increasingly unpredictable labor market means that graduate employment cannot be taken for granted following university graduation, and returning home upon completion of higher education is becoming normative. We also find that gender moderates the relationship among partnership dissolution, parenthood, and returning to the parental home, reflecting the differential welfare support in Great Britain for single parents compared with nonresident fathers and childless young adults

Embryonic diapause in the elasmobranchs

Embryonic diapause is a temporary suspension of development at any stage of embryogenesis, which prolongs the gestation period, allowing parturition to occur in conditions that are more suitable for newborns. This reproductive trait is widespread among all vertebrates, including elasmobranchs. Although it has only been confirmed in two elasmobranchs (Rhizoprionodon taylori and Dasyatis say), evidence indicates that at least 14 species of rays and two sharks undergo diapause, suggesting that this form of reproduction exists within a wide range of elasmobranch reproductive modes, including lecithotrophs and matrotrophs. Where it has been studied, embryogenesis is arrested at the blastodisc stage and preserved in the uterus for periods from four to 10 months. There are still many questions that remain unanswered concerning the knowledge on the biology of most diapausing species but it is clear that species benefit differently from this reproductive trait. As in other vertebrates, it is likely that environmental cues and hormones (especially progesterone and prolactin) are involved in the control of diapause in elasmobranchs, however rigorous testing of current hypothesis remains to be carried out
