Publishing habits and perceptions of open access publishing and public access amongst clinical and research fellows.

Introduction: Open access (OA) publishing rates have risen dramatically in the biomedical sciences in the past decade. However, few studies have focused on the publishing activities and attitudes of early career researchers. The aim of this study was to examine current publishing activities of clinical and research fellows and their perceptions of OA publishing and public access.

Intensive Parenting: Fertility and Breastfeeding Duration in the United States.

Using 30 years of longitudinal data from a nationally representative cohort of women, we study the association between breastfeeding duration and completed fertility, fertility expectations, and birth spacing. We find that women who breastfeed their first child for five months or longer are a distinct group. They have more children overall and higher odds of having three or more children rather than two, compared with women who breastfeed for shorter durations or not at all.
